  • Cooperation is an essential element in mathematics education with independence. We observe cooperative learning and apply it to the education spot. We conducted cooperative learning experiment with students who were not ready for the prerequisite learning of college mathematics. We try to make up the prerequisite learning through collaborative learning to them. We discuss how cooperative learning affects the students who were not ready for the prerequisite learning of college mathematics.

  • 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.

  • We analyzed the HACCP prerequisite of National Veterinary Research and Quarantine Service (NVRQS) and the Food Establishment Inspection Report of US Food and Drug Administration (FDA) to recommend contents and ranges to be complemented and used for preparation of guidelines for more effective application of HACCP prerequisites. We used the HACCP inspection reports implemented by Korea Livestock Products HACCP Accreditation Service from 2007 to 2009, FDA Food Code 2009 Guide 3-B Instructions for Marking the Food Establishment Inspection Report, and Retail Food Establishment Sanitation Requirements of 410 Indiana Administrative Code. Major non-compliance items were open doors and windows, insanitary cleaning of in-use utensil, inadequate record of warehousing, and improper storage, transportation, and labelling. Hot water supply, personal hygiene, and regular product testing were additional week points which should be more strongly controlled by detailed operating guidelines. Also, current prerequisite items were required revision into more precise contents to enhanced the effective evaluation and practical application in meat markets.

  • 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.

  • 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.

  • 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.

  • There has been a need for establishing operational curriculum for chinese characters and chinese writing used by traditional korean medicine (TKM), but it was not carefully recognized so far. We analysed the frequency of unicode chinese characters from five medical textbooks and showed prerequisite chinese characters for TKM beginners. It was found that 之, 者, 不, 也, 而, 氣, 陽, 陰, 下, 其, 病, 爲, 人, 以, 中, 則, 於, 脈, 上, 故 are the most frequently used 20 chinese characters. We also showed that adequate prerequisite chinese character should be designated for the more efficient education of TKM. This study was the first systematic approach to get essential and prerequisite chinese characters for the education of TKM. The prerequisite characters by this study will be used for the development of KEET (Korean Medicine Education Eligibility Test), entrance exam to the Colleges of Oriental Medicine and textbooks, and educational curriculum of premed students.

  • 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.
