The study aims to find a way to guarantee high school students choose science subjects by exploring its necessity as a prerequisite for admission to university science and engineering major courses. For this purpose, a survey was administered to 516 science & engineering college students to investigate their cognition and completion of the prerequisite science subjects related to their major, department adjustment, and influence on their major of study. Among nine major clusters, Physics was identified as a science domain with a high relevance to majors in five major clusters, and Chemistry in three. The students who completed both science I and II subjects related to their majors responded most positively to the usefulness of prerequisite subjects to their studies. Suggestions include conditions for the opening of science II subjects, strengthening the connection between science subjects and IT, promotion of linkage between the prerequisite subject and major studies to assert students' choice of science subjects in high school.

The purpose of this study is to explore ways to secure highschool students' choice of courses in order to improve highschool - university linkage. For this purpose, we conducted in-depth focus group interviews with a total of 10 students in the second or the third year or graduate student at the science and engineering college, and these interviewees were recommended by their professors. Through interviews, the necessity to complete highschool science prerequisite courses, reason for not completing highschool science prerequisite courses necessary for college major, their intention to recommend highschool juniors to complete science prerequisite courses, and ways to guarantee prerequisite course completion for college major studies. Based on the results, we suggested ways to link highschool - university curriculum for science & engineering majors. Discussed in the conclusion are ways to stabilize highschool curriculum organization and implementation such as opening elective courses with a few students without disadvantage in the school record, improving the grading system for Science II courses in the school record as well as the College Scholastic Ability Test, providing career guidance about prerequisite courses by science & engineering majors, improving the science teacher's professionalism on teaching and career guidance, and developing college entrance systems to guarantee the completion of prerequisite courses for science & engineering college studies.

HACCP system application has been expanded to livestock products chain from farm to table in Korea. However, it requires flexible application with modified simple model in order to activate its application in small businesses such as butcher shop. We calculated non-compliance rates to identify weak points of prerequisite requirements and choosed main contents to be controlled as a simplified prerequisite program in butcher shops. The data used for the analysis of non-compliance rates were based on the HACCP accreditation evaluation inspection reports conducted by Korea Livestock Products HACCP Accreditation Service. Among the existing 51 evaluation items, we suggested 28 items of prerequisite requirements for the butcher shops.

The purpose of this study was to determine food safety practices and procedures based on Hazard Analysis Critical Control Point (HACCP) system and to suggest more effective method of HACCP implementation in meat packaging industry in Korea. We used the non-compliance rate of each evaluation item to compare the weak points of prerequisite requirements and HACCP. The prerequisite items related to facility, equipment, and tools showed inadequate level of requirements or unsanitary conditions for proper HACCP operation. A lack of understanding of sanitation standard operation procedures was identified as a fundamental barrier to HACCP implementation. High rate of non-compliance in HACCP items compared to prerequisite requirements signify that small businesses have potential difficulties of applying HACCP due to lack of technical expertise, financial resources for prerequisite requirements, and available personnel to prepare and operate HACCP plan. Also we suggest to revise and minimize current critical control points (CCPs). Time-temperature control of cold-storage rooms for carcasses and final products could be performed by control points of prerequisite requirements. As the occurrence frequency getting lower, metal detector should be replaced by intensified training of sanitary handling and safety procedure. This will be more effective and preventive measures against physical contaminants including metal particles. In conclusion, control point of prerequisite requirement may replace CCP in the plant with simple processing line and no heating process such as meat packaging industry.

The purpose of the study was to investigate the HACCP systems of contract foodservice establishments by surveying HACCP plans and prerequisite programs from the twelve HACCP-implemented contract foodservice establishments appointed by KFDA. All the subjects (100%) appeared to develop HACCP plans with their own hazard analysis. Except the two giving no response, it turned out that two establishments had 2 CCPs (20%), four had 4∼5 CCPs (40%) and another four had 9 CCPs (40%). Especially, 'cleaning and sanitizing of raw vegetables and fruits (90%)' and 'cooking (temperature) (100%)' were monitored as CCPs by all the subjects. Only one subject (8.3%) answered that continuous monitoring was not conducted. But the verification, record keeping and internal audits were maintained by all the subjects (100%). Most of the surveyed foodservice establishments maintained various prerequisite programs enough to back up HACCP system.

We analyze the HACCP Prerequisites of National Veterinary Research and Quarantine Service (NVRQS), Korea Food and Drug Administration(KFDA), and US Food Safety and Inspection Service (FSIS) and recommend contents and ranges to be complemented and used for the preparation of guidelines. We used the HACCP Notice of the Processing Livestock Act, the HACCP Application Manual for Livestock Processing Plants, the HACCP Notice of the Food Sanitation Act, US GPO 9 CFR and 21 CFR, US FSIS Directive 11,000.1, and HACCP-based Inspection reference guide of Consumer Services, North Carolina Department of Agriculture. The Prerequisites of NVRQS and KFDA are composed of 66 and 84 items respectively, without detailed guidelines for their application. This may decisively affect the application in the field and the evaluation activities. Water supplies, washing and disinfection monitoring tools, and examining and correcting plan are required to be improved. If the standards of compliance of each Prerequisite item as well as performance guidelines are given, the application and evaluation will be performed more effectively. The evaluation items should be associated with Prerequisite operations such as non-compliance complement, self-evaluation, and record keeping. Hazards found during official inspection should be promptly controlled not to contaminate the work places and processing items. As the HACCP is expected to spread from farms to tables, the standardized Prerequisite program among the official governments should be prepared.

Gifted education, receiving private tutoring and prerequisite learning, is emerging as a remarkable phenomenon currently in Korea. Hence, we need to find out that whether prerequisite math learning influences academic achievement in any aspect after they enter the center. In this paper, we investigate the effect of mathematics prerequisite learning of gifted students focused on the their self-efficacy, achievement motivation and academic achievement. As a result, the period of mathematics prerequisite learning did not influence academic achievement of gifted students. However, the correlation between self-efficacy and achievement motivation was positive.

This study is to develop a new scoring system for rating Hazard analysis and critical control points prerequisite evaluation items for meat shops to provide a more objective and accurate evaluation of food safety compliance. The importance of each item was measured by looking at the hazard severity level and the rate of non-compliance associated with it. It was found that the new scoring system is more stringent and gives a clearer picture of compliance with the most critical safety standards, and therefore is expected to have a positive effect on the hygiene and safety of livestock products.

The purpose of this study was to analyze factors that influence prerequisite program (PRP) performance of hospital foodservice operation. Data was collected through surveys given to 65 dietitians working in general hospital with ${\geq}100beds$. Importance score of sanitary management for the self-operated establishments was significantly higher than that of contract-managed in the areas of working environment management (p<0.01), waste management (p<0.05), clean disinfection management (p<0.05). Performance score of hospitals with ${\leq}300beds$ was significantly lower than that of hospitals with ${\geq}300beds$ in personal hygiene management (p<0.05). Moreover, importance score of dietitians spending ${\geq}3hours$ on inspection time was significantly higher than that of dieticians spending ${\leq}3hr$ in waste management area. According to the results of Pearson correlation analysis, PRP performance score was positively related with dietitian's career (p<0.05), number of submitted beds (p<0.05), cooking process inspection time (p<0.05), dietitian's job satisfaction (p<0.01), and holding rate of utensil and equipment (p<0.05). In addition, the results of multiple regression analysis showed that dietitian's job satisfaction (p<0.001) and holding rate of utensil and equipment (p<0.05) had a significant positive effect on prerequisite program performance. In conclusion, improvement of working condition to increase dietitian's job satisfaction and securing of utensils and equipments are high priorities for improvement of PRP performance.

This study was conducted to estimate the shelf-life of Kimbab manufactured using a Hazard Analysis and Critical Control Point (HACCP). We performed a microbiological verification after applying the HACCP plan to Kimbab. Additionally, the shelf-life of Kimbab at each holding temperature was calculated as a regression equation between the aerobic plate counts and holding time during the storage period. The critical control points of the HACCP plan, that were applied to Kimbab, included: cold-holding of refrigerated foods, checking the endpoint cooking temperature of heated food, and cold-holding of cooked foods. As a result of the microbiological verification of Kimbab, the aerobic plate counts averaged 3.46 log CFU/g. In contrast, the coliforms, E. coli, Staphylococcus aureus, and Salmonella spp. were not detected in any of the samples. The estimated shelf-life of Kimbab was calculated to be 45 hours at $10^{\circ}C$, 29 hours at $15^{\circ}C$, 6 hours at $25^{\circ}C$ and 3 hours at $35^{\circ}C$. In conclusion, manufacturers should apply a prerequisite program and a HACCP system for a safe consumption of ready-to-eat foods and label products with a proper shelf-life. Distributors should control the proper holding time-temperature until sale and consumers should eat immediately after purchasing ready-to-eat foods.
