  • This study was conducted to examine the effect of HACCP implementation on the cost of medicine use, antibiotic utilization, and productivity of swine in Korea. Data were collected from forty-five swine farms before and after implementation of a HACCP system. The cost of medicine used, the number of different antibiotics used and the number of feeds containing antibiotic supplements added at the feed company tended to be lower (p>0.05) after HACCP implementation. Additionally, the number of feeds containing antibiotics supplemented at the farm was significantly lower after HACCP implementation (p<0.05). Moreover, the number of piglets born per sow per year and pigs marketed per sow per year were higher after HACCP implementation (22.0, 20.0) than before HACCP implementation (20.4, 18.9). These results suggest that implementation of HACCP systems on swine farms may provide beneficial effects such as reduction of medical expenses and improved productivity, as well as increased safety of livestock products for consumers.

  • Eyes to the Future (ETF) is a year-long, multi-age mentoring program that supports middle-school girls as they make the transition to high school and make informed choices about the opportunities available to them in high school and beyond, particularly in the field of science and technology. In this study, we explore the tension between fidelity and adaptiveness of an educational innovation by examining how teachers in several different schools used a common set of materials and technology to create "native" implementations of an innovative after-school program, adapted to their local setting. First, we found that the implementation of the program varied across the nine clubs. For example, some clubs put a heavy emphasis on science while others emphasized technology. Then, we identified four different profiles of the variations in implementation based on how close the implementation was to the original program and how much clubs were able to customize the implementation to meet their needs and interests. The results showed that some clubs could be regarded as successful because they were faithful to the original program and others were successful because they could adapt the program for their own context. This implies that the measure for success can be and should be multi dimensional.

  • The purpose of this study was to analyze science teaching models: Cognitive Conflict Teaching Model(CCTM), Generative Learning Model(GLM), Learning Cycle Model(LCM), Hypothesis-Testing Model(HTM), and Discovery Teaching Model(DTM). Using literature review, the models were analyzed and compared in several aspects; philosophical and psychological bases, primary goals and assumptions, syntax, implementation environments, and probable effects. The major finding were as follows; 1. Science teaching models had been diverse features. In the comparisons of science teaching models, some differences and similarities were founded. These were different in the degree of similarity and emphasis. 2. CCTM and GLM resemble each other in philosophical and psychological bases, primary goals and main assumptions, implementation environments, and probable effects. 3. LCM and HTM showed similarities in philosophical bases, syntax, and implementation environments. But differences were founded in other aspects These results showed that the diverse features of science teaching models should be considered in choosing a model for science teaching.

  • The objective of this study was to investigate the problems and benefits associated with the implementation of HACCP on livestock product of plants in Korea. The survey was carried out by randomly selecting 115 HACCP accredited meat processing plants, all across the country. A total of 105 complete responses were selected for analysis. The results were as follows: approximately 60% of the respondents employed less than twenty workers. The average period of operating HACCP system was 3.4 years. The respondents replied that the major incentive to implement the HACCP system was to improve hygiene management ability. More than half of the respondents (59.05%) claimed that the implementation of the HACCP system cost less than 400 million won, and the highest investment in terms of cost was the freezer/refrigerator. In the preparation period taken to implement the HACCP system, the 6-12 mon category had the highest percentage (55.24%). Most respondents replied that there was an increase in the customer satisfaction, plant image and turnover, after HACCP implementation (p<0.05). A total of 98.09% of respondents had the opinion that their plant workers had improved in their understanding of food hygiene by HACCP implementation (p<0.05). Approximately 79% of respondents indicated that customer complaints decreased, as a result of HACCP implementation.

  • Recently ERP(Enterprise Resource Planning) package has been on of important issues in developing information systems in many Korean companies. The main objectives of this study are to analyse the case of implementing ERP system in Samsung Display Devices Co. which is rated to be successful, and to derive significant implications for effective ERP implementation. First, this study focused on showing the detailed roadmap of performing ERP implementation project which largely consists of 5 stages(planning and organizing, visioning. process redesign and mapping, testing and arrangement, and installation and roll-out to overseas subsidiaries), and explaining key activities in each stage. Second, the performance of this project was evaluated on the basis of both process-centered critieria and result-centered ones. Finally, this study intended to discuss and explicate the bottlenecks and the critical success factors in implementing this project. The findings of this case study are thought not only to be useful as a practical guideline in carrying out ERP implementation project but also to provide significant basis for constructing the theoretical framework of effective ERP implementation.

  • The purpose of this study, based on a domestic sample of businesses using EDI systems, is to identify success factors, which affect the implementation of EDI system by Korean business entities. This paper also intends to provide useful guidelines for the establishment and management of EDI systems. This paper, first, develops a conceptual framework based on pervious research to identify factors which affect successful implementation of EDI system. Second, it integrates the constructs from previous research studies into a single survey instrument. Third, it presents the findings regarding the degree to which each factor influences the successful implementation of EDI system. It's revealed in the study that such factors as EDI vendor support, EDI education and training, participation by transactional partners, the size of organization, and the level of decentralization among organizational and environmental characteristics influence successful implementation of EDI systems in Korean business environment.

  • This research has seven factors such as top management leadership, belt system operation, implementation of systematic methods, adequate project performance measurement, customer focus performance, quality performance and business performance. Those are critical to correct implementation of Six Sigma. I set seven hypotheses which represented the relationships among the seven factors, gathered questionnaires and analyzed the data. Top management leadership affected positively the adequate project performance measurement and the belt system operation, The belt system operation affected the implementation of systematic methods positively and it also affected the adequate project performance measurement. It affected positively the customer focus performance, the quality performance and the business performance, respectively.

  • In this paper, we review the lowest order staggered discontinuous Galerkin methods on polygonal meshes in 2D. The proposed method offers many desirable features including easy implementation, geometrical flexibility, robustness with respect to mesh distortion and low degrees of freedom. Discrete function spaces for locally H1 and H(div) spaces are considered. We introduce special properties of a sub-mesh from a given star-shaped polygonal mesh which can be utilized in the construction of discrete spaces and implementation of the staggered discontinuous Galerkin method. For demonstration purposes, we consider the lowest case for the Poisson equation. We emphasize its efficient computational implementation using only geometrical properties of the underlying mesh.
