Cook-serve method in mass catering establishments: is it still appropriate to ensure a high level of microbiological quality and safety? Abstract The purpose of this study was to evaluate the hygienic quality of three traditional “cook-serve” catering establishments in Lombardy, Italy (with an output ranging from 800 to 1700 meals a day), by monitoring the microbiological quality and safety of foods ready for consumption (n = 727), tap water (n = 32), microfiltered drinking water (n = 28), food contact surfaces (n = 280), and food handlers (n = 76). The food contact surfaces showed unacceptable contamination in 17.1% of samples. The hygienic level of the washed hands of food workers was very high, since only 1.3% of samples showed unacceptable contamination. Food sample analyses highlighted a percentage of samples that did not conform to microbial reference standards: the presence of Listeria monocytogenes was found in 11.5% of “soft cheese” samples. Staphylococcus aureus non-conforming percentages ranged from 2.2% for “first and second courses” to 34.6% for “soft cheeses”; Escherichia coli, from 2.7% for “raw vegetables” to 7.7% for “soft cheeses”; total coliforms from 6.7% for “first and second courses” to 76.4% for “raw vegetables”. The results of the water analysis indicated a high frequency of contamination with Pseudomonas aeruginosa (21.4% for microfiltered drinking water and 21.9% for tap water samples). In conclusion, the results suggest that more effort should be made in the application of HACCP principles. In addition in order to ensure a higher level of microbiological safety of meals, various changes in the timing of food preparation and holding temperatures are needed. Food safety in commercial catering Abstract The catering industry plays a very important role in public health management, because about 30% of total daily meals are consumed in catering industry establishments (restaurants, cafeterias bars). In this context, food safety was evaluated in 20 catering centres by means of microbiological analyses of different categories of meals. Results demonstrate that there was a significant decrease in microbial contamination between 2006 and 2007; no pathogens were found in 217 samples examined; this result was obtained by improving voluntary controls. Monitoring the bacteriological quality of Italian bottled spring water from dispensers Abstract The bacteriological quality of unprocessed bottled spring water was evaluated, through enumeration of heterotrophic plate count at 22 and 37 °C, total coliforms, Escherichia coli, intestinal enterococci and Pseudomonas aeruginosa. The aims of the research were to monitor the hygiene of bottled spring water and to evaluate the effectiveness of the dispenser sanitation procedure, reproducing field conditions. In total, 120 water samples were analyzed. The results indicated a high contamination frequency with P. aeruginosa (57.5%) and therefore the need to refine hygiene in the bottling plant and in the dispenser sanitation procedures. Microbiological quality and safety of refrigerated precooked lasagna packaged under modified atmosphere for Italian school catering Abstract The aim of this study was to evaluate the microbiological quality and safety of refrigerated precooked lasagna prepared in a traditional “cook-serve” centralized kitchen for up to 28 days of storage. Two preparation methods (hot and cold sauce layering) and two materials (polyethylene and cellulose) for packaging under a modified atmosphere were tested. Microbiological analyses focused on pathogenic and potential-pathogenic microorganism markers (Salmonella spp., Listeria monocytogenes, Bacillus cereus, Escherichia coli, Staphylococcus aureus, and spores of sulphite-reducing clostridia), and on the evolution of spoilage-hygiene markers: mesophilic and psychrotrophic aerobic bacteria, total coliforms and lactic acid bacteria. In total, 81 samples were analysed at intervals of 7 days. No pathogenic microorganisms were detected in all the samples examined for up to 28 days of storage. 37% of samples were positive for S. aureus. After cooking all the samples were in a situation of conformity according to the limits established. In conclusion, the hot sauce layering method associated with polyethylene packaging resulted the most effective productive solution for prolonging the shelf-life of packaged precooked lasagna for up to 21 days.

Many rural communities in South Africa do not have running water or electricity. The fetching and heating of water is therefore a time consuming and expensive daily ritual. The use of energy sources such as wood or coal are not readily available and cause environmental pollution. Although solar water heaters are commonly available in South Africa, they are very seldom used in rural areas. Whilst this can mostly be attributed to a high system cost, current designs also do not cater for specific rural problems such as the transporting or purification of water. A prototype model, designed with such an approach in mind, has already been constructed by TEMM International (Pty.) Ltd. The Solar Heat Barrow (SHB) was developed in the 1992 to 2003 period with the intention of combining a number of functions at low cost. Specific requirements were: low cost, a suitable design and materials for manufacture in large volume, sufficiently durable taking into account the harsh conditions of use. suitability for cases where no in-house piped water supply was available, the use of appropriate technology and the improvement of quality of life. The unit combines the absorption of solar radiation, the heating of a relatively small volume of water, the transport of the water from the point of supply and the storage of the hot water until it is used. Untreated water sources such as surface waters (streams, rivers, lakes, etc.) or unprotected open wells are the vehicles for waterborne bacterial diseases such as cholera and typhoid fevers. In the case where water is collected from these sources, the SHB has a build-in Purification Dispenser that purifies the water in the collector against waterborne bacterial diseases. Certain research questions need to be answered. They will be answered by demonstrating the SHB in two communities where no in-house piped water supply is available and by establishing the socio-economic response of the users. The research questions are as follow: What are the responses of the users concerning the SHB, in comparison to those of a control group, regarding its operation, durability, utility and satisfaction of needs? What is the daily use of hot water and the reduction in energy use and cost? To what extent will the target community purchase the SHB at the full or subsidised commercial price? Is there a business case that can be developed for the large scale production, marketing. financing and Small, Medium and Micro Enterprises (SMME) development of the SHB? It was decided to choose a community in the Valley of Thousand Hills in KwaZulu Natal as the demonstration site. The name of the community is Mabedlane. It is a remote rural area 20 km's north of Botha's Hill and is situated along the Umgeni River. The community is dependent on the river for domestic water. Most families are headed by women. The area has low levels of infrastructure, poor roads, a high unemployment rate and poor health facilities. The first survey, which was conducted before the test period started, showed a very positive response from potential users. From 112 questionnaires that were given to the people of Mabedlane, all indicated that they were interested in a product that can transport and heat water for domestic use. The socio-economic study has shown that the price per unit needs to be adapted as 85% of the people who participated in the survey indicated that they would only pay less than R100 for the product. 15% indicated that they would pay between RlOO and R200. From the second and third questionnaires it was clear that the users were satisfied with the heating performances of the SHB. The community was very interested in purchasing a SHB. They have realised that a SHB will improve their standard of living and regard it as a necessity in their day to day activities. It is apparent that people, who will benefit from a SHB most, are those who will not be able to pay the full retail price. Therefore, new business strategies have to be researched when implementing the SHB to the target market in South Africa. The idea of considering ways to sponsorlfund the SHB must also be investigated.

The rational use of resources is a recurring theme in sustainable development discussions and has stimulated the development of more efficient electrical power consumption appliances. Regulators and Certifiers agencies set standards for the functionality requirements and for the electric power consumption classification of devices in order to formalize the relationship between performance and maintenance of these resources indefinitely. Thus a model based predictive controller was applied to a thermoelectric cooler to attain the international standard ANSI18 specifications for water cooler dispensers and to meet ENERGY STAR$ iny^{ extregistered}$ energy efficiency requirements. A phenomenological linear model was obtained and the respective parameters were identified by using least squares algorithm; experiments were performed to identify the parameters of the discrete transfer functions; a model criterion selection based on simulation capabilities and residue characteristics was developed; a model based predictive controller was designed and applied using one of the models identified; the controller performance was analyzed attending to the ANSI18 standard and according to energy performance certificates; a comparative study between the bistable control and the proposed strategy was made for performance analysis. Simulation and experimental tests have shown compromise between the simulation capability and residue characteristic criterion. The closed loop system behavior allowed energy saving in standby temperature regulating compared to thermostat control mode. The new control strategy achieved ENERGY STAR energy-efficiency criteria certification requirements infeasible for traditional regulation.

Nowadays with the growth of economy, the demand of safe and clean drinking water is rising. The water dispenser with filters which provides clean water has become more popular and a necessary part of modern life. The subject of this research is water dispensers in schools. By collecting maintenance records, we analyzed the reliability to find out the most frequent failed component. People make mistakes. Once involved people, there must be human errors. The studies on reliability usually focused on hardwares, instead of the influence of human factors. Therefore, this research used SHELL model to develop the human factors of the water dispensers, and measured the influence of human factors by the conversion of Fault Tree Analysis into Bayesian Network. We hope that this research may arouse the facility managers’ attention to the relationship between human factors and reliability of water dispensers. At last, this study may be the reference of further researches on reliability analysis and factor revaluation on water dispensers.

Water is crucial thing for human to live. Most important part of water is as a source for human to fulfill the needs of its body by drinking it. However, in Taiwan, water from tap is not safe. Thus many of people in Taiwan use water dispenser to take a drink. Focus on water dispenser, it also consumes a lot of energy by repeating the process such as heating and cooling on its water tank even no one uses it. Having this kind of situation, we take a chance of it by attempting to predict water consumption in water dispenser and utilizing sleep mode feature on water dispenser to save energy from it. Doing prediction with Recurrent Neural Network, we also tried to maintain the service level of water dispenser by putting sleep mode on “right time” since on this mode dispenser does not do any process either heating or cooling Those previous two statements are the main objective of this research. Focusing on water dispenser in university environment surrounded by office and labs, internal data such as water taken from water dispenser and energy usage of water dispenser is collected by attaching sensors on water dispenser that sent data either for each minute or someone takes water from dispenser. Besides internal data, external data is acquired also. We do feature selection to all attributes and Savitzky Golay filtering to water consumption data. Result of feature selection shows: Working and Not Working Hour”, “Temperature”, “Dew Point”, “Clustering Result”, “Consumption Classification”, and “Seasonal Index” are relevant attributes that correlate with water consumption data. For RNN parameters, combination of parameters produces the lowest of error on testing set is: LSTM activation is hard sigmoid, recurrent activation is hard sigmoid, and dense activation is tanH. While on this combination, dataset which utilize filtering water consumption value and related attributes gives the lowest value among other. Based on that parameters combination and dataset. dispenser could save energy about 0.86% of a whole week usage and service level decrease 1.2%

Drinking water is an important way in which humans stay alive and remain healthy. Ensuring a sufficient water intake is particularly important among the elderly, and this is especially true in the morning, when water in the body has evaporated as perspiration during sleep. Because blood pressure rises when water in the body is reduced, it is easy for life-threatening illnesses such as strokes, thrombosis and myocardial infractions to occur in the morning. This study is aimed at issues affecting aging societies in developed countries around the world, and looks at guided morning water dispensers designed for elderly people who live alone and lack sufficient care. The design steps are divided into two stages, each of which includes the design of morning water dispensers and interviews with elderly people about how satisfied they were with the design. Apart from using a guiding system to encourage elderly people to get into the habit of drinking water in the morning, the design concept also incorporates orange technology, which aims to provide care and meet basic human needs, and the Internet of Things, which people around the world are striving to help develop. The aim is for the design of the morning water dispenser to combine reminders, interactivity and care technical functionality. Analysis of the design and interviews with elderly people in the two sections yielded the following discoveries: (1) Elderly people are willing to be guided by the water dispenser in drinking water after they get up in the morning, and acknowledge the health benefits of this; (2) It is safer and more convenient to install the water dispenser in the bathroom as opposed to at the top of the bed; (3) Elderly people’s satisfaction with their quality of life could be increased if the water dispenser also provided reminders and information about important things that needed to be done (such as taking medicine); (4) The water dispenser could send everyday drinking and life information of the elderly to the relatives. This means the elderly can be taken care of on a full scale.

The main purpose of this study is to validate the feasibility of the refrigeration and heating equipment that is a vapor compression refrigeration system driven by a treadmill directly. Furthermore, this equipment not only achieves the goal of maintaining health but also makes the normal temperature water into hot or chiller water bestowing from the kinetic energy during exercising. This kind of equipment taken for drinking purpose is called “Exercise-driven-type Water Dispenser.” The experiment setup has three experiment modes: Motor only driving mode, Motor combined with Manpower driving mode, and Manpower only driving mode. By carrying through threes experiments, the acquiring data would serve as the basis of performance investigation and further analysis. In the mean time, we establish a mathematical model in order to validate the reliability of experiment data and feasibility of this new type refrigeration system transmitted by treadmills. The experiment results of testing on the human indicate that running about 20 minutes drops 15℃ of the average temperature in the 1.3 kg water and releases 96kJ cold energy. In terms of producing hot energy, running about 20 minutes raises the water about 20℃ by absorbing 188kJ heat energy. By analyzing both experiment data and performance investigation results, this innovative refrigeration system transmitted directly by treadmills can actually obtain the goal of producing chiller and hot water and exercising for body fitness at one time. Finally, we take discussion and comparison between the calories consumed by humans and the performance parameters of the system.

Drinking water dispenser has become a basic necessity and has been a common sight in private properties and public places in Taiwan. Typical drinking water dispenser in Taiwan provides 3 levels of water temperature: hot, warm, and cold. Even though it is found to be convenient for user, providing various temperature of water that can be readily available on demand makes drinking water dispenser the 5th most electricity-consuming household appliances in Taiwan. High energy consumption comes from the process of heating and cooling to maintain water temperature in the tank. Repeated processes of cooling and heating may generate energy waste when there is no demand of drinking water at some periods of time. This study proposes data-driven control strategies for drinking water dispenser. Control strategies discussed in this study are constructed based on available data collected from sensors and smart meter installed on the dispenser along with related external data. Based on available data, five predictions model are built: electricity power usage, hot consumption status, cold consumption status, hot water temperature, and cold water temperature. Electricity power usage and water temperature prediction models are constructed using Multi-Layer Perceptron (MLP) method while water consumption status prediction model is built using random forest technique. These five prediction models are used to construct an optimization model to minimize electricity power usage with considering water temperature and water consumption constraints by scheduling heating and cooling processes. The optimization model is solved using Particle Swarm Optimization (PSO) method. A case study has been conducted to evaluate the performance of the proposed model. Data on 14 January 2019 on peak hours used in the case study. The results show 6.3% energy-savings could be achieved while still maintaining satisfaction level of cold water at 100% and hot water satisfaction level at 95.83%. However, this result may not be accurate since prediction models need to be improved.

The goal of the present research is to discover the new energy conservation method and the technique, due to the earth resource has consumed excessively. In order to use the few remaining resources effectively, how to reduce the waste of resources has become the most important topic now-a-days. The present thesis proposed the energy conservation theory based on the heat pump´s principle, imports the application of heat pump system into the traditional water dispenser to enhance the using efficiency of the compressor. The traditional water dispenser emits the condenser heat directly into the atmosphere while making the cool water; the condenser heat was not recovered neither collected for other usage. A heat preservation barrel has been made and installed into the traditional water dispenser to forms a circulator system of heat pump. Fill water into the internal of heat preservation barrel and let the high temperature reefrigerant flows through the surface of the barrel. Because of the heat exchange´s principle the condenser heat was transmitted to the water inside the barrel. Through the heat collected by the heat preservation barrel while making cool water, it can enhance the temperature of the water inside the barrel up to 10℃, and this heat value can reduce the energy consumption of the electric heater at the same time reduce the water heating-up time. The key point of the experiment is how to concentrate and collect the waste heat. The experimental method is installed two open-shut gate valves into the traditional water dispenser. A gate valve controls the refregerant flow into the original un-recovered pipeline, as the comparison group; the other gate valve controls the Freon to flow into the pipeline of heat preservation barrel, as the improved group. Using the water as the medium and record the changes of water temperature, in order to calculate the compressor´s efficiency and the actual hot value recovered by the hot water. The result of this research proved that the traditional water dispenser with heat pump system imported, the compressor´s efficiency has been enhanced about 19.9% concretely. If convert it into the heating efficiency of hot water, it enhanced the power about 13.6%. The greatest value of this thesis is the usage of heat pump´s principal as an important energy conservation technique for the traditional water dispenser manufacturers.

Household daily electricity usage varies due to individual’s chosen life style or family needs. The lack of knowledge in energy consumptions and willingness to learn or understand the utilization of limited energy resources effectively makes it difficult to integrate efficiently usage of energy in day to day life. According to an article related to energy consumptions, household electricity usage can be grouped into lighting, air conditioner and home appliances and it states that family electricity usage is dominated by household appliances. Hence, this research focuses on water dispensers, refrigerators, televisions and desk top computers (CPU & display). The research has been conducted through monitoring three households with electricity usage throughout the two weeks. The features of electricity usage are analyzed and the customized strategies for saving electricity are suggested. There is a significant difference between the result of monitoring four kinds of household appliances in three households and other published papers. There is a difference between each family member’s acknowledgment of energy usage and the monitor result. The accuracy reaches 33.3% only. As a result, household energy consumption should be monitored individually in order to present the real situation. The research exhibits that ten of twelve home appliances under monitoring are used more frequently during weekends than weekdays. Desktop computers, televisions, refrigerators and water dispensers are ranked from the greatest to the littlest in terms of variance. Among them, refrigerators and water dispensers are operated continuously and there’s a basic consumption rate associated. Hence, the energy consumption is less likely to be influenced by the users. On the other hand, televisions and desktop computers are used intermittently; therefore, the intervals and peaks are reflected. This paper proposes saving energy strategies for the three subjects respectively based on monitor results and suggests turning off water dispensers when no one is home. Moreover, when desktop computers and television are not used, the power should be isolated. With this practice, each household is estimated to save 14.7 watts of energy per month. This study presents the effective saving energy strategies for each subject according to the monitor result of electricity usage features. To conclude, monitoring is recommended for future saving energy researches. It is also suggested for air conditioning studies in order to increase the efficiency of saving energy. Last but not the least, power suppliers are encouraged to put efforts in household electricity monitoring and provide saving energy service in the market.
