Abstract:

My students and I have developed a LOTUS 1-2-3 spreadsheet to aid in data reduction tasks associated with preparing powder diffraction data for publication in the Powder Diffraction File (PDF) (1987) and this journal. Portions of a sample spreadsheet and the formulae in each of the computational cells are given in the Table 1. The concept of this spreadsheet should apply to any of the available computer spreadsheet programs, although the specific codes for the mathematical functions may differ.The user enters data only into columns C, D and F-H. All other entries will be calculated from the input data. Observed 2θ angles are entered into column D. The corresponding d-spacing is calculated in column A. The Miller indices of these peaks are entered into column C. Prior to use of the spreadsheet, the observed 2θ angles and hkl's had been used to refine unit cell parameters using the Appleman and Evans (1973) least squares unit cell parameter refinement computer program implemented for the IBM PC by Garvey (1986).

Abstract:

The significance of indirect costs in the cost price calculation of clinical chemistry laboratory tests by way of the production centres method has been investigated. A cost structure model based on the ‘production centres’ method, the Academisch Ziekenhuis Groningen (AZG) 1-2-3 model, is used for the calculation of cost and cost prices as an add-in tool to the spreadsheet program Lotus 1-2-3. The system specifications of the AZG 1-2-3 cost structure model have been extended with facilities to impute all relevant indirect costs to cost centres by aid of allocation rules, which can be chosen freely. The inference is made that as indirect costs play a more important part in decision-making processes concerning planning and control, the specification of the relation to the cost centres should be determined in a more detailed way. The AZG 1-2-3 cost structure model has therefore been extended in order to increase the significance as a management tool for laboratory management.

Full text

Abstract:

Spreadsheet programs, such as Microsoft Excel, Informix WINGZ, and Lotus 123, provide a framework for very fast and easy development of simple engineering models. The present paper describes a model of the continuous casting process that has been developed using a spreadsheet program, Microsoft Excel, running on a Macintosh II personal computer. The model consists of two-dimensional (2-D) steady-state finite-difference heat conduction calculations within a continuous casting mold coupled to a one-dimensional (1-D) transient solidification heat transfer model of the solidifying shell. The model structure and equations are described and the model predictions are compared with previous solutions. Practical examples using the model are discussed and sample results are provided. Spreadsheet programs running on personal computers are capable of relatively complex calculations that would require extensive effort using conventional programming languages.

Full text

Abstract:

A “user friendly” microcomputer-generated data management system designed for on-site documentation and immediate analysis of patient parameters during cardiopulmonary bypass is presented. The program is a macro-driven template for use with Lotus 1-2-3 (ver. 2.0) on IBM PC-XT or compatible such as the Zenith Z-183 Laptop computer used in this report. Automatic calculation of data requiring minimal input includes kilos, centimeters, body surface area, blood flow, fluid balance, heparin, protamine and mannitol dose and systemic vascular resistance. Also included is autocomputation of documented minimum, maximum and average pressure, blood flow, oxygen flow/percent, temperature, activated clotting time and SVR. Basic file functions are easily performed as saving, retrieving, deleting and report generation. Database management capabilities include sorting by contents of fields, searching for specific records and graphing of selected parameters. The use of a computer-generated perfusion record has become a valuable tool in the tracking and evaluation of important patient parameters during cardiopulmonary bypass.

Abstract:

Abstract. INTRODUCTIONBy far the most widely available computer programs for recording, manipulating, and displaying numerical data are spreadsheets, such as Microsoft Excel™ and Lotus 1-2-3™. These are powerful and flexible tools and for most workers this is an obvious way of recording micropalaeontological data. However, they have been primarily produced for business users and have limited abilities when it comes to plotting scientific graphs. This note describes some indirect but rapid methods, for using the standard graphing tools in such packages, to produce additional types of graphs of value to micropalaeontologists.STACKED HISTOGRAM CHARTSFigure 1 is a stacked histogram chart, produced in Microsoft Excel™. This type of diagram is useful, for instance, in displaying variations in size of a species between samples through a section. Stacked histogram charts are not directly supported by any spreadsheets that I have seen. As a result, they can usually only be produced by rather inefficient techniques. For example, making a separate chart for each sample and then combining them in a graphics program. The indirect approach used here is to separate each true data series with a mirror image padding data series, which is not displayed. The entire diagram is then plotted as a single chart. The steps for doing this are:(1) Enter the data (specimens per size class) in a spreadsheet (samples v. size classes).(2) Between each pair of data columns insert a column with equations which will calculate mirror image padding data. These will have the form C3 = . . .

Abstract:

The lack of knowledge about parenting has led to several cases of violence against children. Providing training on parenting skills is a possible solution. This study was presented with the aim of knowing the effectiveness of a mobile parenting training program based on ubiquitous learning to improve parenting skills moderated by parental locus of control. This study used a quasi-experimental design with control and experimental groups. Sampling in this study used purposive sampling with the following criteria for parents: 1) Having children aged 3-6 years, 2) Parents experiencing parenting problems, 3) Children experiencing developmental delays, 4) Willing to participate in the training program to completion. The tests used in this study include testing the validity and reliability of the instrument, classical assumption test, homogeneity test, and hypothesis testing using Two Way Anova parametric statistics. The results of this study can be concluded that a mobile parenting training program based on unbiquitous learning moderated by a good parental locus of control can improve parenting skills in parents.

Abstract:

The impact of grouping, learning handicap, locus of control, and self esteem on students' performance on a math problem-solving program was assessed in two studies. Outcome measures included: 1) the level of difficulty at which students selected to work, 2) use of a program help command, and 3) response accuracy with and without help. Despite indication from the non-computer instructional literature that grouping would facilitate problem-solving skills for some students, neither problem selections nor performance accuracy varied as a function of group configuration. Personal characteristics influenced problem selections, help seeking, and accuracy in anticipated directions but not consistently. More consistent patterns were noted as a function of initial student competency in math.

Abstract:

Napier (Pennisetum purpureum) fodder is an important fodder supporting livestock systems in Bangladesh. Using gamma irradiation we developed 48 Napier fodder mutants which were analyzed through morpho-molecular characterization. Among 48 Napier fodder mutants, 41 mutants were originated by applying radiation (20Gy, 30Gy, 40Gy and 50 Gy) on them. The Napier mutants showed variations in survival rate and fresh weight. The survival rate (0-75%) was observed, 20Gy treated plants produced higher fresh weight in Napier-2, Napier-3, Rokona, Markiron grasses; whereas, 30Gy treated plants produced higher fresh weight in Napier-1, Napier-4 and Pakchong. The total of the alleles found in molecular characterization were 17 and the mean number of allele per locus was 3.4. The PIC value ranged from 0.3047 to 0.6587 having an average of 0.4704 per locus. The highest gene diversity (0.7101) was observed in primer Xipes0093 and the lowest gene diversity (0.3750) was observed in primer PSMP2255, having an average diversity of 0.5286. Pair wise genetic distance values ranged (0.0-1.0) with highest between Napier-2 40 Gy vs (Napier-1control, Napier-2 20Gy Napier-2 30Gy), Napier -3 control, vs (Napier-1control, Napier-2 20Gy Napier-2 30Gy), Napier- 3 20Gy vs (Napier-1control, Napier-2 20Gy Napier-2 30Gy) ,(Napier-3 20Gy, Napier-3 30Gy Napier-1 20Gy, Napier-3 50Gy) vs (Napier -2 20Gy, Napier-3 control, Napier-3 20Gy) etc. The UPGMA displayed five major clusters including sub-clusters. Cluster 5 included the highest number of genotypes (21) and cluster 3 included the lowest number of genotypes (2). The results may be useful for future breeding program for Napier fodder development.

Abstract:

Traditional urban design is time-consuming and laborious. We propose a computer-generated architecture (CGA)-based workflow in this work, with the goal of allowing designers to take advantage of a high level of automation. This workflow is based on procedural modeling. A three-step CGA rule was applied to implement 3D urban procedural modeling, (1) parcel subdivision and clustering, (2) building extrusion, and (3) texture mapping. Parcel subdivision and clustering is the key step of layout modeling, giving the modeler flexibility to adjust the placement and size of the inner building lots. Subsequently, a land-use-based combination of eight common building types and layouts was used to generate various urban forms for different urban functional zones. Finally, individual buildings were decorated by creating texture maps of a planar section of the building facade or, alternatively, decomposing facades into sets of repeating elements and texture maps. We employed the proposed workflow in the H-village urban redevelopment program and an air–rail integration zone development program in Guangzhou. Three design proposals were generated for each project. The results demonstrated that this workflow could generate multiple layout proposals and alternative facade textures quickly and, therefore, address most of the collaborative issues with its analysis functions, including a flexible adjustment mechanism and real-time visualization.

Abstract:

The genetic mechanisms of resistance, clonal composition, and the occurrence of pili were analyzed in 39 pneumococcal strains isolated from healthy children in the southeastern region of Poland. Strains with resistance to combinations of erythromycin, clindamycin, and tetracycline were found in clonal groups (CGs) related to Tennessee 23F-4 and Taiwan 19F-14 clones. Capsular switching possibly occurred in the Spain 9V-3 clone and its variants to serotypes 35B and 6A, as well as DLVs of Tennessee 23F-4 to serotype 23A. The double-locus variants of Colombia 23F-26 presented serotype 23B. The major transposons carrying the erythromycin and tetracycline resistance genes were Tn6002 (66.6%), followed by Tn916 (22.2%) and Tn2009 (11.1%). The macrolide efflux genetic assembly (MEGA) element was found in 41.7% of all erythromycin-resistant isolates. The majority of the isolates carrying the PI-1 gene belonged to the CGs related to the Spain 9V-3 clone expressing serotypes 35B and 6A, and the presence of both PI-1 and PI-2 was identified in CG4 consisting of the isolates related to the Taiwan 19F-14 clone expressing serotypes 19F and 19A. Importantly, in the nearest future, the piliated strains of serogroups 23B, 23A, and 35B may be of concern, being a possible origin of the emerging clones of piliated non-vaccine pneumococcal serotypes in Poland. This study reveals that nasopharyngeal carriage in children is an important reservoir for the selection and spreading of new drug-resistant pneumococcal clones in the community after the elimination of vaccine serotypes.

Abstract:

With the mass introduction of computers in the workplace researchers have spent considerable time, over the last two decades, investigating methods to effectively integrate this technology into the daily routines of employees at all levels within the organization [1–3]. An exogenous variable, and precursor to introduction of computers, is computer anxiety [4–6]. Computer anxiety is generally defined as an anxious response by the individual to the anticipated or actual contact with computers [7]. This article examined the relationship of cognitive appraisal, locus of control, prior exposure, and computer anxiety. It was hypothesized that an individual's appraisal of a computing situation, whether the person was internally or externally focused, and their prior experience with computers would affect their level of computer anxiety as measured by the Computer Concerns Questionnaire. A stepwise multiple regression was performed and the results indicated that cognitive appraisal and exposure were significant predictors of computer anxiety. The authors conclude that early assessments of a novice user's appraisal of the situation should be used to tailor training programs to the specific individual's needs.

Abstract:

Introduction. Today we observed of tendency to reduction of honey bee population in the world what according to honey gathering. For example, in Ukraine, according to statistical data for 7 inhabitants of Poltava region accounts for 1 bee familie, compared with that of 300 years ago, it reached within 3 bee families per citizen. Science and practice open many secrets according biology of bees, allowing bee efficient manage vital functions for humans. But despite the opening of beekeeping is the only farm animal that over 100 years has not been the intervention of human hands to create a new breeds of honeybees. Genetic intensify the search in the field of beekeeping conditions in Ukraine needs to initiate breeding program as planned waste zoning and aspects of reproduction of bees. The aime of research: determining the characteristics of four intrapedigrees types in the Carpathian bee breed using the methods of population and molecular genetics. Materials and Methods: Sampling was performed from top five lines: Sinevir, Rakhiv, Vuchkivskyy and Hoverla bee colonies were taken 10 bee worker. For molecular genetic analysis used 20 insects of each Carpathian bees breed type with observance of the principle of representativeness. DNA extraction performed from homogenate tissues using the standard commercial kit «DNA Sorb B», «Amplisense», this some modifications [1] during sample preparation. Reaction mix purification from bees wax leading this octane. The structure of the primers used for genotyping of bees and their code designations are: OPA-1(3’- CAG GCC CTT C -5’); OPA-4 (3’- AAT CGG GCT G -5’); B15 (3’- GGA GGG TGT T -5’); S1 (3’-AGC AGC AGC AGC AGC AGC C-5’). The program amplification of RAPD - primers: 1 cycle: 940 - 3min .; 2-35 cycle: 940 - 1 min., 360 - 30s., 720 - 1hv.36 cycle (final elongation): 720 - 10 min. The program amplification with primers S1: 1 cycle of 94 ° C - 4min 2 - 31 cycle: 57 ° C - 2 minutes; 72 ° C - 4min; 94 ° C - 1 minute, 32 cycle: 57 ° C - 3 minutes; 72 ° C - 7 minutes. Electrophoretic separation of amplified sections performed in 2% agarose gel in Tris borate buffer conditions. Size of amplification products control was carried out using molecular weight marker 1 kb - Ledder plus ( «Fermentas», Vilnius, Latvia). Processing of the profiles was performed in a standard computer program GELSTAT [4]. Genetic distances were calculated in terms of genetic similarity indices obtained GELSTAT program as follows: Dxy = - lnI Building a kladohramm performed according to the values of genetic distances TREE program and MEGA 4 [5; 6]. Statistical analysis of amplicon frequencies, heterozygosity, linage similarity, etc., performed by Fisher's algorithm [7]. Results and discussion. Molecular genetic studies on four primers made it possible to analyze 95 DNA fragments of different lengths, matching the same number of anonymous genetic loci of the genome of bees. Apply primer in RAPD - 15 made it possible to identify 18 amplification products in a range of molecular sizes from 410 to 1000 b. p. It noted that the DNA fragment size 410 b.p. 100% met all the members of Carpathian bees breed and described one genetic monomorfic locus. DNA size band 445 b. p. elektrophoregramme was found in only 20% of bees Vuchkivskiy type in the absence of individuals in other populations. Statistical comparisons (Fisher's criterion) frequency distribution of DNA fragments obtained with primer in -15 revealed a significant number of types of identification markers intrapedigrees of Carpathian bees. The largest number of DNA - fragments set for Vuchkivsksy type whose size is reached within the following limits: 1000, 630, 580 and 485b.p. DNA fragment of 1000 b.p. general was absent in bees Rakhiv type and Synevir, and its frequency in the population of Representatives Hoverla was 0.600 (p <0.001). As individuals, the members of such Synevir, observed no amplicon size 630 b. p. A fragment of a molecular weight of 710 b. p. observed with a frequency of 0.600 to 0.400 bees and type Rahiv, Goverla and 0,100 individuals in such Vuchkivskyy (p <0,05; p <0,01), respectively. Bees type Rahiv, Goverla and can be identified among other types of Carpathian breed presence significantly higher frequency amplification product whose size is 655, 515 b. p., 830 b. p, 530 b. p., respectively. Statistical analysis of the frequency distribution of the products of amplification bees four types derived from molecular genetic analysis of four primers in PCR was performed to identify the most characteristic identification of DNA fragments bees each of type [8]. Based on these characteristics were constructed genetic formula intrapedigrys types of Carpathian breed. According genetic formulas the highest number of specific DNA - fragments characterized by bees for types of Sinevir and Vuchkivskyy, that the overwhelming number of such markers has been found Sinevir system ISSR-S1 (four amplicons) and for the type of system was Vuchkivskyy informative method of RAPD B-15 primer (six DNA fragments). Type Rahiv different from the others by the presence of six DNA markers, such as bees of Hoverla characterized only four specific genetic loci. For the main parameters of population parameters highest level of genetic diversity characterized types Goverla and Rahiv because in terms of total heterozygosity significantly different from the type of bees from Sinevir and Vuchkivskyy values of 0.362 and 0.354, respectively (p <0,01; p <0,001). Moreover, the type of bees Hoverla observed the largest number of polymorphic loci - 54.9%, with a minimum of meaning in a population of individuals Sinevir type, and the lowest value of intrapedigrys similarity (number of DNA fragments in the same study group) were observed for a sample of bees type Rakhiv (0.665, p <0.001). Determining the genetic distances between breeds in genealogical structure can be used as a methodical approach predicting the effectiveness of a combination of lines and types for heterosis effect on purebred descendants basis.The maximum value of genetic distance algorithm M. Ney was established between the types Synevir and Rakhiv (0.435), slightly less than this value typical of the combination VUChK - Synevir (0.426) and VUChK - Rakhiv (0.423). The smallest genetic distance calculated between individuals and types Hoverla ‒ Vuchkivskyy, which indicates their high genetic relationship and the undesirability of crossing the representatives of these types together. Application of unweighted pair-group clustering based on the calculated distances made it possible to analyze the nature of the genetic relationships between intrapedigrys types of Carpathian breed in graphic terms. According dendrogram representatives Synevir types and Rahiv presented by individual branches, indicating their genetic identity. The Goverla and Vuchkivskyy type of bees and united in a common underklaster, due not only to the minimum calculated measure of genetic distance between data types, but confirmed the historical part of the establishment pedigree group Hoverla, based line mares are exactly the type Vuchkivskyy and lost insect genealogical group of Kolochavskiy type. Conclusion Determining genetic specificity linage types of Carpathian breed bees allowed to obtain the following results: 1) chosen for the study of molecular genetic markers is sufficiently informative for determining the unique, specific features of each breed group and the identification of any sample Carpathian bees with the opportunity to consider linage certain type; 2) received genetic formula of Carpathian bees linage types are proof of the impact of breeding activities and can form the basis the protection of intellectual property of their authors; 3) used molecular genetic markers may serve as a forecasting tool optimal compatibility of linage types to obtain heterosis effect in their offspring. The prospect of the research of this area is to select as a methodological tool for measuring genetic polymorphism Carpathian breed more accurate, reproducible and standardized markers, locus-specific micro satellite analysis, STR, research of structural genes single nucleotide polymorphism, SNP analysis, accumulation and formation the databases to assess the state of development, management and preservation unique of Carpathian bees gene pool.

Abstract:

A simple Lotus 1-2-3 model of the flow of golfers through a high-demand championship golf course was developed to help course managers understand the course’s queuing problems better. The nature of the queuing problem, the Lotus 1-2-3 model, and its use in golf course management are discussed. The key to understanding the dynamics of golf is to recognize the similarities (and differences) between golf and assembly lines. Extension of this idea and computer simulation modeling to other recreational services is proposed.

Abstract:

Recent research advocating the educational value of engaging primary students in authentic integrated STEM inquiry projects also identifies challenges for teachers aspiring to high-quality student-learning experiences. Teachers require support to integrate disciplines, prioritise processes and reasoning over curriculum content, and increase student autonomy in purposeful STEM projects. Within the context of a year-long professional learning program in Australia, an innovative tri-level approach to skill-building for teachers and their students has been developed. The three levels of ‘STEM Skills’, ‘Design Process’ and ‘Integrated STEM Projects’ are intended to successively escalate demands on time, resources and pedagogical change while promoting the development of the dispositions and skills needed to engage in sustained inquiry projects. The teacher participants (n = 11) came from five schools who had just concluded the STEM Academy professional learning program. Semi-structured interviews guided teacher reflection. Data analysis combined inductive and deductive processes to thematize meaning and revealed ways in which the tri-level approach to STEM education supported the development of STEM integration practices. The findings suggest the efficacy of the tri-level approach and its potential value beyond the context in which it was developed.

Abstract:

Coumarin-based compounds containing a chalcone moiety exhibit antimicrobial activity. These substances are potential drugs and it is important to determine their pKa values. However, they are almost insoluble in water. The dissociation constant was experimentally determined by potentiometric titration for 3-[3-(2-nitrophenyl)prop-2-enoyl]-2H-1-benzopyran-2-one because this compound shows good activity and solubility. A number of different computer programs for the calculation of the dissociation constant of chemical compounds have been developed. The pKa value of the target compound was calculated using three different computer programs, i.e., the ACD/pKa, CSpKaPredictor and ADME/ToxWEB programs, which are based on different theoretical approaches. The analysis demonstrated good agreement between the experimentally observed pKa value of 3-[3-(2-nitrophenyl)prop-2-enoyl]-2H-1-benzopyran- 2-one and the value calculated using the computer program CSpKa.

Abstract:

Internode starch biosynthesis is one of the most important traits in lotus rhizome because of its relation to crop productivity. Understanding the microRNA (miRNA) and mRNA expression profiles related to lotus internode starch biosynthesis would help develop molecular improvement strategies, but they are not yet well-investigated. To identify genes and miRNAs involved in internode starch biosynthesis, the cDNA and small RNA libraries of Z6-1, Z6-2, and Z6-3 were sequenced, and their expression were further studied. Through combined analyses of transcriptome data and small RNA sequencing data, a complex co-expression regulatory network was constructed, in which 20 miRNAs could modulate starch biosynthesis in different internodes by tuning the expression of 10 target genes. QRT-PCR analysis, transient co-expression experiment and dual luciferase assay comprehensively confirmed that NnumiR396a down-regulated the expression of NnSS2 and ultimately prevents the synthesis of amylopectin, and NnumiR396b down-regulated the expression of NnPGM2 and ultimately prevents the synthesis of total starch. Our results suggest that miRNAs play a critical role in starch biosynthesis in lotus rhizome, and that miRNA-mediated networks could modulate starch biosynthesis in this tissue. These results have provided important insights into the molecular mechanism of starch biosynthesis in developing lotus rhizome.

Abstract:

Objectives The purpose of this study is to analyze the perception level of university students regarding ChatGPT using the Borich Needs and The Locus for Focus model. Methods For this purpose, a total of 199 undergraduate students from University A in the metropolitan area were selected as participants, and the research was conducted using SPSS 25.0 and Excel software programs. Statistical significance was analyzed using t-tests to examine the differences between the current level and im-portance in IPA analysis.Borich'sNeeds and The Locus for Focus Model were examined in a 2x2 matrix, divided into four quadrants. Results The key findings of this study are as follows: First, in the IPA analysis, the reinforcement and maintenance area(HH) revealed 2 items related to understanding ChatGPT, 5items related to ChatGPT principles and applica-tions, and 1 item related to data and machine learning. The concentration management area(HL) included 1 item related to ChatGPT principles and applications, and 3 items related to data and machine learning. The low priority area(LL) consisted of 1 item related to understanding ChatGPT, 2 items related to ChatGPT principles and applica-tions, and 4 items related to social impact. The excessive area(LH) was characterized bybiaseddata in the social impact category. Second, it was found that the differences between importance and current level were higher in terms of importance for all items, except for those related to data bias. This difference was statistically significant. The priority order according to Borich's needs includes 'structuredand unstructured data', 'sensorsand perception', 'computer vision', 'concepts of AI agents' and 'conceptsand application learning of machines'. Third, The Locus for Focus model analysis revealed that the HH area consisted of 9 items, including 'speech recognition and language understanding', 'problem solving and exploration', 'representation and deduction of information', 'concepts and ap-plication learning of machines', 'concepts and application of artificial neural networks', 'data attributes', 'structured and unstructured data', 'classification models', and 'machine learning model implementation'. Fourth, a total of 6 items, including 'speech recognition and language understanding', 'representation and deduction of information', 'concepts and application learning of machines', 'concepts and application of artificial neural networks', 'structured and unstructured data', and 'classification models' were consistently rated as high priority and demanded the high-est attention. Conclusions The findings of this study indicate the need to explore ways to apply ChatGPT in education. Furthermore, it proposes a long-term education plan to enhance awareness of the social impact of ChatGPT and provide practical strategies for learning and applying it.

Molecular characterization of 26 modern rice varieties of Bangladesh was performed using 52 simple sequence repeat markers (SSRs) to estimate the genetic diversity and to reveal genetic relationships among rice cultivars. A total of 156 alleles were detected where the number of alleles per locus generated by each marker varied from 2 to 7, with an average of 3. The band size for a given microsatellite locus ranged from 79 to 278 bp. The polymorphism information content (PIC) for the SSR loci ranged from 0.08 to 0.79, with an average of 0.35. RM566 was the best marker for identification and variability assessment of varieties as revealed by PIC values. A UPGMA dendrogram generated using the NTSYS-pc revealed four clusters with a similarity coefficient of 0.55, whereas phylogenetic cluster analysis of the SSR data based on Nei-genetic distance divided the varieties into three groups. Two- and three-dimensional graphical views of principal coordinate analysis showed the spatial distribution of the varieties and revealed that BRRI dhan56, BRRI dhan51, BRRI dhan52, BRRI dhan61, BRRI dhan62 and BRRI dhan66 were found far away from the centroid of the cluster. The findings of this study are helpful for varietal identification, background selection during backcross breeding and for selecting the suitable genetically diverse parents for crossing programs.

Program komputer yang dikembangkan dapat menentukan skor tes siswa menurut teori tes modern dengan baik. DEVELOPING OF COMPUTERIZED NATURAL SCIENCE TESTAbstractThis study is aimed at: (1) describing the caracteristics of Natural Science test developed, and (2) describing a computer program which had been developed to determine the test scores of students with modern test theory. Natural Science test consists of 600 items and had been tested in junior high school throughout Solo Raya with 1,800 respondents. Data analysis technique which was used is R programming. The computer program had been developed and tested in SMP Negeri 4 Polokarto (Polokarto 4 Junior High School). The results of the analysis of Natural Science program test with R programming show that: (1) item difficulty is in the range of -2.001-1.713, (2) discriminatory power of items is in the range of 0.553-2.394, and (3) the supposition of items is in the range of 0.000-0.379. The computer program developed can determine students’ test scores according to the modern test theory well.
