Rapid and accurate industrial inspection to ensure the highest quality standards at a competitive price is one of the biggest challenges in the manufacturing industry. This paper shows an application of how a Deep Learning soft sensor application can be combined with a high-resolution optical quality control camera to increase the accuracy and reduce the cost of an industrial visual inspection process in the Printing Industry 4.0. During the process of producing gravure cylinders, mistakes like holes in the printing cylinder are inevitable. In order to improve the defect detection performance and reduce quality inspection costs by process automation, this paper proposes a deep neural network (DNN) soft sensor that compares the scanned surface to the used engraving file and performs an automatic quality control process by learning features through exposure to training data. The DNN sensor developed achieved a fully automated classification accuracy rate of 98.4%. Further research aims to use these results to three ends. Firstly, to predict the amount of errors a cylinder has, to further support the human operation by showing the error probability to the operator, and finally to decide autonomously about product quality without human involvement.

The construction industry has embraced digitisation and industrialisation in response to the need to increase its productivity, optimise material consumption and improve workmanship. Additive manufacturing (AM), more widely known as 3D printing, has driven substantial progress in these respects in other industries, and a number of national and international projects have helped to introduce the technique to the construction industry. As with other innovative processes not covered by uniform standards, appropriate assessments and testing methodologies to control the quality of the 3D-printed end products, while not obligatory, are advisable. This article shows that regulation is not an obstacle to the use of an innovative product, such as 3D printing, by proposing quality-control tests and an assessment methodology, in the understanding that standardisation ensures the viability of a technology. The information, including the methods and results, is based on the authors’ experiences in the development of three research projects pertaining to 3D printing. This paper also discusses whether the performance of the materials used in 3D printing could be superior to traditional ones.

Full textAbstract:
The aim of this review is to present the factors influencing the mechanical properties of 3D-printed oral dosage forms. It also explores how it is possible to use specific excipients and printing parameters to maintain the structural integrity of printed drug products while meeting the needs of patients. Three-dimensional (3D) printing is an emerging manufacturing technology that is gaining acceptance in the pharmaceutical industry to overcome traditional mass production and move toward personalized pharmacotherapy. After continuous research over the last thirty years, 3D printing now offers numerous opportunities to personalize oral dosage forms in terms of size, shape, release profile, or dose modification. However, there is still a long way to go before 3D printing is integrated into clinical practice. 3D printing techniques follow a different process than traditional oral dosage from manufacturing methods. Currently, there are no specific guidelines for the hardness and friability of 3D printed solid oral dosage forms. Therefore, new regulatory frameworks for 3D-printed oral dosage forms should be established to ensure that they meet all appropriate quality standards. The evaluation of mechanical properties of solid dosage forms is an integral part of quality control, as tablets must withstand mechanical stresses during manufacturing processes, transportation, and drug distribution as well as rough handling by the end user. Until now, this has been achieved through extensive pre- and post-processing testing, which is often time-consuming. However, computational methods combined with 3D printing technology can open up a new avenue for the design and construction of 3D tablets, enabling the fabrication of structures with complex microstructures and desired mechanical properties. In this context, the emerging role of computational methods and artificial intelligence techniques is highlighted.

Full textAbstract:
Additive manufacturing (3D Printing) has become a promising manufacturing method as it can produce parts in a flexible and efficient way, especially for very irregular parts. However, during the printing process, the material experiences a great temperature change from the melting temperature to room temperature; this causes high thermal strains and induces distinct deformations which degrade the quality of the printed parts, especially in metal 3D printing. In order to reduce possible problems and find possible solutions, a prior evaluation by simulation is often adopted. Nevertheless, since the 3D printing process generates parts in a layer-by-layer way, the analysis model should also be layer-by-layer arranged and used with a layer-by-layer based analysis process to simulate the layer-by-layer additive printing; otherwise, the simulation may not match the real behavior. In order to meet these requirements, a new meshless method is proposed to match the situations and handle these problems. As a meshless method, the modeling is not constrained by the element distribution. In addition, the analysis model generated with the proposed method can be arranged in a layer-by-layer way and combined with the proposed layer-by-layer analysis scheme, so it can then match and simulate the printing processes. Furthermore, the layer-by-layer arranged models can be automatically created, directly based on the STL (STereo-Lithography) geometry model, which is a de facto standard in the 3D printing industry. This makes the proposed approach more straightforward and efficient. To validate the proposed method, two parts with holes inside have been printed and simulated for comparison. The results show a good agreement. In addition, a highly irregular part has also been simulated to demonstrate the effectiveness and efficiency of this proposed method.

Проблема повышения точности контроля в процессе производства различных печатных изделий не теряет своей актуальности в связи с совершенствованием как технологий изготовления самих изделий, так контрольно-измерительной техники и методов контроля. Поскольку нанесение красочного изображения, выполняющего информационную функцию, на печатное изделие способами печатания осуществляется на достаточно высокой скорости, то широко используемый метод визуального контроля малоэффективен, применим выборочно, не позволяет обеспечить требуемую точность. Следствием этого является брак или ухудшение качества напечатанных изображений на печатных изделиях. Показано, что действующие методы контроля, регламентированные стандартами, не отвечают требованиям для выпуска конкурентоспособной на современном рынке продукции В работе проанализированы стандартные и запатентованные методы контроля показателей качества, нанесенного на печатное изделие изображения способами печатания. Отмечены направления их модернизации и разработки новых объективных методов контроля, что возможно осуществлять только за счет использования современных систем с применением программых продуктов, разработанных под конкретный объект контроля, способствующих интеграции процессов измерения и анализа информации для стабилизации технологического процесса печати. Предложен метод контролякрасковосприятия, который основан на методах математического и гармонического анализа. Ввиду отсутствия стандарта, разработан алгоритм контроля показателя укрывистость. Оценка и контроль укрывистости в данном алгоритме базируется на методах математической статистики. Определение и контроль показателей красковосприятия, укрывистость осуществляется с помощью разработанных программ для ЭВМ, что позволяет не только существенно сократить время контроля, но и повысить его точность. Providing that both current processing techniques and supervisory instruments is updating, the problem of the accuracy quality parameters continues to be relevant for printing industry. Due to high-speed processes of the printed items manufacturing the current visual-based monitoring techniques can be thought of as low informative, selective applied resulted in accuracy decreasing at lot inspections. The most current monitoring methods regulated by standards are low-efficient at the moment. Both standard and patented quality monitoring techniques for printed images monitoring were analyzed. The listed techniques upgrading trends and points of the novel objective ones developing based on specified software hardware integration of measurement and information analysis procedures aimed at the operational process stabilization are noted. The ink trapping monitoring technique based on both mathematical and Fourier analysis is proposed. As long as the standard procedure is deficient, the algorithm of covering power control based used mathematical statistics approaches was developed. The monitoring is carried out by the developed software.

To expend the printed color gamut is the most important area for today’s print quality. Conventional wide gamut printing technologies utilize six or seven colors. However, these processes increase the complexity and the cost. Therefore, the four-color wide gamut inks are becoming the major development in Taiwan’s printing industry. This study is focused on the print performance study of the four-color wide gamut inks in the domestic market that are complied with the RoHS regulations. In this study Tung-Ming and K+E wide gamut process inks were tested for their print performance. The press control was to comply ISO12647-2 specifications. The test forms were printed on both type 1 and type 2 papers that specified in ISO12647-2. The normal process ink set was also printed to compare with those wide-gamut color ink sets. The result shows that the both wide-gamut ink sets have reached color gamut larger than the ISO12647-2. In this study shows that the domestic normal process ink set can comply the international standard, and the developing wide gamut ink also reach the standard. However, the color characteristics and printability have to test before using these wide gamut color ink sets. With the optimized process control and color management system, the four-color wide gamut inks can produce the best color result on paper.

Managing a business such as a garment must have clear organizational structure, financial management, and production implementation so that company goals can be achieved according to the targets set by a company. The purpose of this research is to describe the business studies in "Vandev" Garments, especially in the production implementation section, which includes the manufacturing process of 3 products, namely jackets, jersey products, and shirt products. In this study, researchers used a descriptive research design with a qualitative approach. Checking the validity of the findings using source triangulation and triangulation techniques Based on the results of the researcher's findings that, all implementation of the production section is in accordance with the Indonesian National Work Competency Standards starting from the process of preparing product samples, the pattern making process, the process of spreading cloth, the process of cutting cloth, the process of numbering the materials, grouping the materials that have been given number, screen printing / embroidery, sewing process, finishing, cleaning clothes from thread remnants (trimming), packaging ironing process. The production implementation process is carried out in each worker's home, so that quality control is carried out every 2 days. Even though production is carried out in each worker's house, it does not change the quality of the product. When the trimming process uses the manual method instead of using a metal detector machine, you must be more careful in checking the product. The product marketing process is not only from within the country but has reached abroad. Suggestions for Garments "Vandev" regarding production management as input to further improve the skills of production employees. The last suggestion is for other researchers that this research can be an input and a reference for similar research but with a more detailed and more detailed discussion of the garment business study, so that it can add new insights for other researchers.
Mengelola suatu usaha seperti garmen harus jelas struktur organisasinya, pengelolaan keuangan, serta pelaksanaan produksinya agar tujuan perusahaan bisa tercapai sesuai target yang ditentukan suatu perusahaan tersebut. Tujuan dari penelitian ini untuk mendeskripsikan studi usaha yang ada di Garmen “Vandev” terutama pada bagian pelaksanaan produksi meliputi proses pembuatan 3 produk yaitu jaket, produk jersey, dan produk kemeja. Pada penelitian ini peneliti menggunakan rancangan penelitian deskriptif dengan pendekatan kualitatif. Pengumpulan data yang diperoleh peneliti mulai dari proses wawancara 2 karyawan dan 1 pemilik garmen, observasi saat proses produksi berlangsung, serta dokumentasi saat proses produksi. Pengecekan keabsahan temuan menggunakan triangulasi sumber dan triangulasi teknik. Berdasarkan hasil temuan penelti bahwa, semua pelaksanaan bagian produksi telah sesuai dengan Standar Kompetensi Kerja Nasional Indonesia mulai dari proses menyiapkan contoh produk (sample), proses pembuatan pola, proses mengelar kain, proses memotong kain, proses penomeran pada bahan, pengelompokkan bahan yang sudah diberi nomer, sablon/bordir, proses menjahit, finishing, membersihkan pakaian dari sisa-sisa benang (trimming), proses penyetrikaan pengemasan. Proses pelaksanan produksi dilakukan di rumah masing-masing pekerja, sehingga quality control dilakukan setiap 2 hari sekali. Meskipun produksi dilakukan di masing-masing rumah pekerja tidak merubah kualitas produk tersebut. Saat proses trimming menggunakan cara manual bukan menggunakan mesin metal detector sehingga harus lebih teliti dalam memeriksa produknya. Proses pemasaran produk bukan hanya dari dalam negeri melainkan sudah sampai ke luar negeri. Saran bagi Garmen “Vandev” mengenai pengelolaan produksi sebagai masukan untuk lebih meningkatkan keterampilan para karyawan bagian produksi. Saran yang terakhir yaitu bagi peneliti lain bahwa penelitian ini bisa menjadi masukan serta menjadi referensi untuk penelitian sejenisnya namun dengan pembahasan yang lebih diperinci dan lebih detail mengenai studi usaha garmen, sehingga dapat menambah wawasan baru bagi peneliti lainnya.

This study aimed to determine the role of quality control in the printing process of packaging products printed by PT XYZ. The reason why quality should be emphasized was because a good quality will encourage the business progress and decrease the defect or damage. This study used descriptive qualitative method. The data collection methods were collected through interview, literature study and direct observation by the writer. PT XYZ had set specifications and quality control procedures, but the results of printing packaging product were still unmatched with the specifications. There were 3 stages of XYZ quality control starting from quality control of incoming raw materials, quality control in the production process, and quality control of finishing. The inspections carried out during the printing process aimed to ensure that the printing results met the standards and specifications set by the company as a proof from the customer. Thus, it could reduce the risk of products that did not meet the printing quality standards which later continued to the next process and sent to the customer.

As a result of miniaturization new avenues were open toward customizing, improving and rendering separation science more affordable and available to any laboratory worldwide. One of the best resolving liquid separation techniques that still benefits from miniaturization is capillary electrophoresis (CE), where analytes are separated by their hydrodynamic volume to charge ratio. The theory of CE was introduced almost one hundred years ago, but became popular in the 1970s, yielding by 2010 over 1000 papers produced yearly. This progress triggered sample preparation optimization efforts, which led to significant reduction of required chemicals for analysis and the decrease of overall sample processing times. Consequently, CE can be considered as a sustainable technique in the field of liquid phase separation science. In this paper a custom made, cheap capillary electrophoresis unit with LED induced fluorescent (LedIF) imaging detection was used to demonstrate applicability of modern electronics, consumer products, and 3D printing in generating scientific results, while keeping sustainability in mind. Samples were chosen according to the observed trends of the past decade, namely from biotherapeutics industry. Its golden standard, immunoglobulin G N-glycans were enzymatically digested and the released complex type oligosaccharides were labeled with charged fluorophore, according to one of the most advanced and optimized protocols. Results were compared to separation runs performed on a high quality commercially available instrument, used as the control. Results disclosed in this paper should not be subjected to direct quantitative comparison, but should be rather taken as a technical demonstration of the capabilities of current and future technology, which can be implemented and merged with existing solutions in a sustainable manner.

Color difference used to test the quality of printing products is one of the most important factors in the printing industry. Many new color difference formulae such as CIEDE2000, CIEDE94, CMC(l:c) etc were developed to improve the uniformity. In this paper the color difference formulae have been compared throughout their weighting functions SL, SC, and SH to the CIELAB components , , . In order to test which color difference formula has the better performance in the printing industry they are evaluated by our own data sets. First of all, we developed a printing data set for evaluating color difference with psychophysical methods. And the visual color differences of every pairs were obtained. After that the color difference formula mentioned before were evaluated using the data set with the standardized residual sum of squares (STRESS) methods which has better mathematical properties to evaluate the performance of color difference formulae using ΔV and ΔE than PF/3 that cannot indicate the statistical significance of the difference between two color-difference formulae. The result shows that CIEDE2000 and CIE94 color difference formulae are better than CIELAB and CMC. Finally we recommend that the national standards and occupation standards should be updated and CIEDE2000 should be popularized in the printing industry.

Fifty years have passed since the first commercial inoculants were manufactured in Australia. Before 1953, various Government Agencies supplied mostly agar cultures with New South Wales Department of Agriculture issuing the first peat-based inoculants. There are no data to indicate the quality of these inoculants, but in the early commercial cultures rhizobia were often outnumbered by contaminants and field failures were widespread. A comprehensive system of quality control was developed from discussions between CSIRO and the University of Sydney. Succeeding quality control bodies have continued on the basis of the original scheme. It set inoculant standards, approved and supplied mother cultures to manufacturers annually, tested all batches of peat inoculants before sale and sampled inoculants at the point of sale. In this paper we describe the history of Australian legume inoculants, list the commercial firms and key people involved and the period during which they were active. We tabulate the strains involved, indicate the period of their use and highlight some of the problems encountered with them and with inoculant production. We indicate the personnel who have been particularly active in the quality control of inoculants, the funding bodies who have supported the work and stress the reliance of the control laboratories on the help of many agricultural scientists in Australia. An important part of the control scheme has been the implementing of standards without resort to legislation. This has depended on the cooperation of the manufacturers involved and has allowed flexibility in applying the standards.

Quality control is important in the church and in industry. Two methods for maintaining quality control in the church are membership criteria and external persecution. Traditional societies, Hellenistic Judaism, and the post-apostolic church exercised quality control through the monitoring of minimum standards maintained during the transition phase in rites of passage. Candidates during the transition phase lose their former status and so seek new identities and acquire new skills to qualify for new statuses. Few other occasions in life provide a more significant pedagogical opportunity for promoting personal development and spiritual growth. It is the universal method par excellence for maintaining quality control in societies.

Full textAbstract:
Color management has been applied in the printing industry since 1993. Press papers as one of traditional substrates, its properties impact the quality of color reproductions. At present, almost all kinds of papers contain OBA. OBA works by absorbing ultraviolet wavelengths of the illuminant, emitting fluorescence at blue wavelengths, increasing the amount of light, and making the paper brighter. This effect of OBA is difficult to measure with common spectrophotometers accurately, which creates a mismatch between color proofing and printing. Furthermore, both the printing standards, as ISO 12647-2 defined substrate without fluorescence. It results in some problems in printing conformance using paper with OBA. This research discovered influence of OBA to color samples, derived colorimetric conversion method to correct and compensate the effects of OBA in papers, and demonstrated the efficient of the colorimetric conversion method in color management workflow with soft proofing.

Full textAbstract:
HACCP (Hazard Analysis and Critical Control Points) is an indispensable contemporary system of process control in the food processing industry. In its original meaning this control procedure includes hazard analysis and identification of the points in the production process where the product contamination is reasonably likely to occur resulting in an unsafe product. At the critical points the control of the production process should be severer in order to eliminate or reduce the product safety risks. The aim of implementing a quality management system being quality management, according to the standards of the ISO 9000 series, the formulation of a product that meets "the requirements stated or implied", where the implied requirements refer to the prescribed quality requirements, which, in the food industry above all, comprises safety, it is necessary to build HACCP into the quality system. The application of HACCP principles when introducing a quality system should be extended to those parts of the production process in which the required quality of the product may be at risk.

As comparative data on the precision of 3D-printed anatomical models are sparse, the aim of this study was to evaluate the accuracy of 3D-printed models of vascular anatomy generated by two commonly used printing technologies. Thirty-five 3D models of large (aortic, wall thickness of 2 mm, n = 30) and small (coronary, wall thickness of 1.25 mm, n = 5) vessels printed with fused deposition modeling (FDM) (rigid, n = 20) and PolyJet (flexible, n = 15) technology were subjected to high-resolution CT scans. From the resulting DICOM (Digital Imaging and Communications in Medicine) dataset, an STL file was generated and wall thickness as well as surface congruency were compared with the original STL file using dedicated 3D engineering software. The mean wall thickness for the large-scale aortic models was 2.11 µm (+5%), and 1.26 µm (+0.8%) for the coronary models, resulting in an overall mean wall thickness of +5% for all 35 3D models when compared to the original STL file. The mean surface deviation was found to be +120 µm for all models, with +100 µm for the aortic and +180 µm for the coronary 3D models, respectively. Both printing technologies were found to conform with the currently set standards of accuracy (<1 mm), demonstrating that accurate 3D models of large and small vessel anatomy can be generated by both FDM and PolyJet printing technology using rigid and flexible polymers.

Full textAbstract:
Meat industry generates various wastes such as effluent, emissions and solid wastes that pose environmental and health problems. The effluent released from the meat industries finds its way into the natural water resources and degrade the water quality. The solid wastes of meat industry create a public nuisance by way of foul smell if it is not handled properly. The effluents, as well as solid wastes of meat industries, are possible sources of pathogens that are hazardous to human health. Waste minimization, segregation of wastes and treatment, processing of wastes to make possible recoveries of by-products and the final disposal are the basic steps for containment of pollution from the meat industry. The effluent treatment technologies include primary treatment, secondary treatment and tertiary treatment. Composting, biomehtanation, rendering, incineration and burial are the processes for disposing of the solid wastes generated by meat industries. Appropriate treatment process is selected considering the level of pollution, mode of disposal and the environmental standards. The treatment and processing of meat industry wastes minimize the pollution problems and also give scope for the recovery of by-products such as bone and meat meal, tallow, methane and manure that have commercial values. The meat industries also generate odours that are required to be contained using suitable control devices. The paper seeks to give an overview of the pollution control technologies currently in use for the treatment of effluents and solid wastes, and possible recovery of by-products.

3D printing has been getting increasing attention from both industry and academy in recent years. Unlike traditional construction processes, 3D cementitious material printing requires more accurate control on the pumping flow rate, which is known to be affected by the material rheology. In this paper, the effect of fresh rheology on the flow rate of cementitious material was studied experimentally in 3D cementitious material printing process. The material viscosity was measured via a large gap vane viscometer at different time points after mixing, and printing tests were conducted at the same time period to measure the flow rate based on volume conservation principle. Experiments showed that the flow rate was significantly affected by rheology change with respect to time. An open loop control method was then implemented to harmonize the flow volume per unit length during printing processes to improve printing quality.

Full textAbstract:
Additive manufacturing (AM) is currently one of the most promising and advanced tools to make high-end components. For industrial acceptance of these components, there is a demand for the delivery of high quality parts, certified under recognized standards. Pre-requisites for such certified parts are the certification of the powder feed-stock and the use of qualified facilities. Such a certification and qualification project encompasses different challenges regarding both powder testing and print process stability. Today there are insufficient quantitative acceptance criteria for AM metal powders in the standards. The main challenge is determining which properties to test and how to define some key indicators that can guarantee consistent quality of the end product. To face this challenge several relevant powder properties were tested in order to link powder performance to the properties of the printed material. To guarantee process stability and repeatability, a good knowledge and control of the different process parameters and their influence on the material quality is needed. Hence, an extensive study on the homogeneity of properties over the 3D printer platform was performed. A qualification testing platform was designed to guarantee and periodically check the quality of the printed AM316L material. The proper procedures and parameter settings were determined and fixed. This methodology finally lead to the qualification of the ENGIE Laborelec Powder Lab and the ENGIE Fabricom AM printing facility and the certification of AM 316L material through a recognized external qualification body. This initiative paves the way to ensure industrial acceptance of the selective laser melting process for high quality applications.

Abstract : Quality control of production is an important thing that must be done by manufacturing companies to be able to produce products in accordance with customer orders. Quality Control (QC) is the department that is responsible for maintaining the quality of the products produced in accordance with predetermined standards. This research was conducted at PT Megah Mas Prima, currently the company still uses conventional methods in the process of creating reports on the results of printing and embossed production. The process of entering the recapitulation data of QC results using Microsoft Excel application, this is very difficult for QC staff because there are many criteria and material codes that must be entered so that the process of making reports requires quite a long time and the level of human error is also high. This research has produced an information system that can assist quality control staff in entering QC data, create QC reporting and accelerate the process of delivering data to QC managers and to other parties who need it.

Full textAbstract:
AbstractAdditive Manufacturing (AM) has a large potential to revolutionize the manufacturing industry, yet the printing parameters and part design have a profound impact on the robustness of the printing process as well as the resulting quality of the manufactured components. To control the printing process, a substantial number of parameters is measured while printing and used primarily to control and adjust the printing process in-situ. The question raised in this paper is how to benefit from these data being gathered to gain insight into the print process stability. The case study performed included the analysis of data gathered during printing 22 components. The analysis was performed with a widely used Random Forest Classifier. The study revealed that the data did contain some detectable patterns that can be used further in assessing the quality of the printed component, however, they were distinct enough so that in case the test and train sets were comprised of separate components the predictions’ result was very poor. The study gives a good understanding of what is necessary to do a meaningful analytics study of manufacturing data from a design perspective.

Full textAbstract:
Printing is not a new media technology, but it is continuously being renewed. In this sense, it is an example of novelty going largely unnoticed, woven into the quotidian and ordinary in unassuming ways. One reason for this is the incomplete way we tell the story of printed paper, which privileges narratives of readings, access, and dissemination. To complicate the way media scholars think printing, this article turns to the case of security printing, which produces objects like banknotes and passports that circulate with trust and authority. Here, printing emerges through the specific need to print securely, offering a narrative based on the need for order and protection. The work of security printing, always straddling between art and science, produces artefacts understood as authentic copies. Such a transformation of paper into valuable object relies on the technical artistry of the security printer, who sets the aesthetic and material standards of authenticity through physical features like watermarks, engravings, holographs, special substrates, threads, or inks. Drawing on a close reading of informational materials produced by the major actors of today’s security printing industry, this article explains how the need to print better than the (counterfeiting) competition fuels the need for novelty in the how of printing. It expands on three guiding principles that work in unison to keep printing on paper new: printing as material science, as complex composition, and as the display of matchless quality. Ultimately, this material quality of securely printed papers helps us think about the new in a way that is not tied up to the digital, so that security printing both complicates the way media scholars engage with printing and offers a reconsideration of the ways we categorize and theorize the differences between media ‘old’ and ‘new’.

Full textAbstract:
This study seeks to understand the origins and reasons behind the grammar and style guidelines elaborated by Brazilian broadcasters and video producers and applied to the translated subtitles of cable television shows. The language of the translation is often controlled, and coarse or scatological vocabulary tends to be curbed or avoided, among other restrictions. Brazil was under a military regime from 1964 to 1985, when the media was subjected to strict censorship. Could it be that this heritage still casts a shadow over current policies applied to audiovisual translation (AVT)? To approach this issue, this study outlines the history of censorship applied to content and language during the Brazilian military regime, describes the evolution of the AVT industry in the context of cable television in Brazil, and finally conveys first-hand insights and experiences on language control by quality control professionals. The ultimate goal is to bring these rulemaking processes to light, in an attempt to help improve the dialogue between end clients and service providers, for the benefit of the viewers.

Purpose The usage of additive manufacturing (AM) technology in industries has reached up to 50 per cent as prototype or end-product. However, for AM products to be directly used as final products, AM product should be produced through advanced quality control process, which has a capability to be able to prove and reach their desire repeatability, reproducibility, reliability and preciseness. Therefore, there is a need to review quality-related research in terms of AM technology and guide AM industry in the future direction of AM development. Design/methodology/approach This paper overviews research progress regarding the QC in AM technology. The focus of the study is on manufacturing quality issues and needs that are to be developed and optimized, and further suggests ideas and directions toward the quality improvement for future AM technology. This paper is organized as follows. Section 2 starts by conducting a comprehensive review of the literature studies on progress of quality control, issues and challenges regarding quality improvement in seven different AM techniques. Next, Section 3 provides classification of the research findings, and lastly, Section 4 discusses the challenges and future trends. Findings This paper presents a review on quality control in seven different techniques in AM technology and provides detailed discussions in each quality process stage. Most of the AM techniques have a trend using in-situ sensors and cameras to acquire process data for real-time monitoring and quality analysis. Procedures such as extrusion-based processes (EBP) have further advanced in data analytics and predictive algorithms-based research regarding mechanical properties and optimal printing parameters. Moreover, compared to others, the material jetting progresses technique has advanced in a system integrated with closed-feedback loop, machine vision and image processing to minimize quality issues during printing process. Research limitations/implications This paper is limited to reviewing of only seven techniques of AM technology, which includes photopolymer vat processes, material jetting processes, binder jetting processes, extrusion-based processes, powder bed fusion processes, directed energy deposition processes and sheet lamination processes. This paper would impact on the improvement of quality control in AM industries such as industrial, automotive, medical, aerospace and military production. Originality/value Additive manufacturing technology, in terms of quality control has yet to be reviewed.

AbstractRecent media and consumer interest in the quality of food purchased in supermarkets and other outlets, is placing pressure on the agricultural industry to improve the quality of the product produced. The farmer has in the past been encouraged to produce quantity irrespective of quality, whereas today the emphasis is very much on the latter, with pressure to reduce quantity. Companies supplying the farming community must react to this changed situation, particularly if they are to be able to administer due diligence under the Food Safety Act.Dalgety Agriculture has thus embarked upon a quality initiative throughout the company involving training of staff on total quality management, registration of premises with the British Standards Institute under BS 5750 scheme and the adoption of the hazard analysis using critical control points (HACCP) technique to evaluate the areas of the company's operations where faults could most easily occur. The company has concluded that an approach to quality must be all-embracing involving all facets of our operations. The aim is to aid the company's farming customers in the attainment of a quality product for the customer of that farm.

Rapid globalization of the agrifood industry has important impacts on international trade and quality management (QM). Likewise, the European Union has negotiated a series of bilateral free trade agreements. Of note was the Transatlantic Trade and Investment Partnership (TTIP) with the United States of America, where the debate focused on the mutual recognition and harmonization of quality standards, especially for agricultural and food products. This topic offered the mainstream media excellent substances for coverage. This paper explores German print media, television, and radio on the importance of international quality standards in the agrifood sectors in light of the TTIP. A quantitative and qualitative empirical content analysis was performed to investigate media reporting regarding (a) it is scientific character, (b) the use of the term “quality standards” of the agrifood industry, and (c) the reporting on the agrifood industry and QM linked with TTIP, focused on harmonization. The results showed that interrelations between QM and global trade were not presented to recipients in-depth. A trend toward information asymmetries in recipient’s knowledge is indicated. The study addresses recommendations for future collaborations between media, policy-makers, and further cooperation in the mutual recognition and harmonization of quality standards and control procedures within global trade.

The movement to ensure Ukraine's integration into the EU is a modern direction of the current state reform. A positive reflection of this process is the official adoption of a number of legislative documents in accordance with international requirements, the standards of which regulate the production of safe and quality products, including poultry. Thus, the implementation of the necessary HACCP (Hazard Analysis and Critical Control Point) requirements for product safety and quality at the level of European standards was able to introduce in the country only a small number of large enterprises in the poultry industry. Most medium and small poultry farms in Ukraine have not implemented the requirements of the HACCP standard and international ISO quality standards, which limited their ability to control product safety in accordance with international requirements and became an obstacle to selling their products in foreign markets. A positive and necessary point of implementation of the European biosafety requirements of the HACCP principles is the expanded possibility in carrying out effective and detailed control of safety and quality indicators of food products in the poultry industry. This control should be established by clearly defined components that are interconnected in interconnected technological processes. Such components in poultry hatcheries are: a detailed analysis of critical control points of hazards of each stage of the production process; use of components and raw materials in general; application of timely monitoring, preventive anti-epizootic and corrective measures to prevent danger at all production sites of poultry hatcheries. Thanks to the constant control of all critical control points of dangers in poultry hatcheries, it is possible to achieve the production of safe and high-quality products obtained from healthy poultry in the poultry industry.

Several adverse reports on quality performance drive the need to assess quality management practice in the Nigerian construction industry. Incidences of building failures and in extreme cases, building collapse have been attributed to poor quality management among other factors. This paper assesses the quality management practices of Nigerian construction firms intending to suggest appropriate courses of action for improving quality performance. Data were collected through questionnaires administered to management staff in 20 construction firms in Abuja, Nigeria. Findings from the study show that inspections and statistical quality control techniques are the most widely used quality management tools by construction firms in Nigeria. However, the study found that the preparation of quality management plans (QMP) and quality auditing (a measure of quality assurance in building production), is not popular among Nigerian construction firms. Inadequate planning arrangements for quality, poor communication of quality requirements and lack of awareness of the benefits of quality management were identified as the most significant issues affecting quality management practice. Therefore there is a low uptake of quality management practice principles within construction organizations in Nigeria. Hence, the need to create awareness for implementing quality management principles and concepts in its construction industry.

Full textAbstract:
Ergonomics problems experienced by workers at quality control and screen printing department at Adhi Fashion garment industry are the use of muscle power, work posture, and work time that still not in accordance to ergonomic principle. The workers carry out static and monotonous work for a long time and got 60 minutes pause per day for 6 working days. They were observed often take disguised pause while doing their jobs. They had musculoskeletal disorder with moderate to high scale complaints and low to moderate workload. There are exercises they can do by applicating of dynamic stretching exercise and active rest that can affect whole body muscles as an efforts to improve work posture and minimize taking of disguised pause. This study used treatment by subject design. The number of samples were 13 respondents consist of 8 workers from the quality control and 5 workers from the screen printing. At Period 1 the subject was working without intervention and Period 2 was working with intervention by applicating dynamic stretching exercise and active rest. The musculoskeletal disorder measured by the Nordic Body Map on Period 1 and Period 2. The normality of the data are tested using the Shapiro-Wilk Test. The intervention effect are tested using Paired-Sample T Test and Wilcoxon Sigend-Rank Test. Dynamic stretching exercise and active rest significantly affected to musculoskeletal complaints (p<0.05). There were reduction of musculoskeletal disorder (7.72%). Dynamic stretching exercise and active rest reduced of musculoskeletal disorder of workers at the quality control and screen printing in Adhi Fashion garment industry.

The subject of research is standardization as one of the forms of technical regulation in the food industry of Ukraine, in particular in the production of milk and milk products, meat and meat products, determination of safety and quality parameters of the specified food raw materials and finished products made from those, as well as installations and equipment for the food industry. The purpose of the study is to analyze the state of standardization in the production of dairy and meat products, highlight the existing problems and possible ways to solve them, as well as outline the role that the Technical Committee for Standardization 140 “Milk, meat and products of their processing” should play in these processes. Methods. During the research, a systematic approach was used to research factual materials, in particular scientific and scientific-practical literature, regulatory legal acts, regulatory documents and the like, abstract-logical approach to the synthesis of research results and the formulation of conclusions. The results of the study. National standards of Ukraine DSTU is the base of the technical regulation in relation to food products and methods of their control. The above also applies to standardization in the field of milk and meat products, which is within the competence scope of the Technical Committee for Standardization 140 “Milk, meat and products of their processing”. Technical Committee 140 carries out significant work to develop new and update existing national standards in accordance with its area of competence, in particular, it has significant success in harmonizing international and European standards. As of January 15, 2021, according to the classification code 67.100 (Milk and milk products) out of 203 standards of the nationwide force, 103 standards (50.7%) were developed by harmonizing the relevant international standards EN, ISO, etc. According to the classification code 67.120 (Meat, meat products and other animal products) – 202 units, 26 units and 14.1 %, respectively, according to the classification code 67.260 (Installations and equipment for the food industry) – 99 units, 86 units and 86.9%, respectively. The issue of attracting extra-budgetary funds for the harmonization of international standards and the implementation of the entire range of works on standardization is urgent. The issue of proper regulatory support for the production and operation of specialized technological equipment for food and processing industry enterprises is relevant, for which it is advisable to combine the domestic traditions of standardization with the priorities of safety and hygiene of machines, as well as ecology, which are in force in international practice. Scope of research results. The results of the studies performed will be used in the field of technical regulation, in particular, national standardization, of milk and milk products, meat and meat products, determination of safety and quality indicators of the specified food raw materials and finished products made from it, as well as installations and equipment for the food industry.
