The purpose of this study was to conduct importance and performance analysis of sanitation management in workers at small and medium foodservice industries using HACCP prerequisites. Questionnaires were distributed to 500 small and medium foodservice industry workers in Seoul Gyeonggi province, and a total of 458 responses were used for analysis. Factors with relatively low comparison degree were as follows. 'Handwashing and clean uniform of employee in the workplace', 'regular checking and managing of trapped vermin and rodents', 'checking stocked raw materials', 'recording and filing the results of improved food safety factors', and 'regular cleaning and sterilizing of monitoring tools' factors must be improved along with their performance levels through sanitation education. According to the IPA results, among the 15 HACCP prerequisite factors with high importance but low performance were '2. Regular checking and managing of trapped vermin and rodents', '4. Handwashing and clean uniform of employee in the workplace', '14. Preventing food cross-contamination'. Furthermore, the small and medium foodservice industry IPA with high importance but low performance were 'Regular checking and managing of trapped vermin and rodents', 'Handwashing and clean uniform of employee in the workplace', and 'Preventing food cross-contamination' for the small foodservice industry, along with 'Vermin and rodents control' and 'Recording and filing the results of improved food safety factors' for the medium foodservice industry. Thus, there is a need for reinforced hygiene education through case studies on actual food service establishments to fulfill sanitation guidelines and set amended guides for much-needed items for small and mid-sized food service.

In this paper, we have studied the improvement of operational control for the enhancement of business continuity of information system becoming more important with the development of information technology such as big data, Iot, and artificial intelligence. The operational management and audit guidance of the current information system, which is coming in the fourth industrial age, where various services, data and industries are converged, is based on the existing general information system pattern and needs to be improved. The provision of services at fixed times is linked to the survival of enterprises and countries and serves as a key element. Therefore, it is necessary to study the application of optimized check items of the operation audits to minimize the service interruption damage of the information system and to provide the stable service in terms of business continuity management. To accomplish this, the check items presented in the operational control of the information system were derived by combining the PDCA step contents and 8 resource requirements provided in ISO 22301. From the point of view of increasing the business continuity according to the derivation criteria of the inspection items, the operational inspection check items were derived by exemplifying the improved check items and review items of the information system operation audit and the products to be checked during the operational audit. The check items were divided into management audit improvement check items for service continuity management, and operational audit improvement check items for performance and availability management. The average score of the IT professionals' survey on the suitability of the proposed checklist was 4.63, which was concluded to be appropriate.

The government introduced the comprehensive evaluation bidding system with the goal of pursuing the best value and the global standard in 2016. However, for the evaluation criteria on the construction evaluation reflected to the comprehensive evaluation bidding system, the problems of the objectivity insufficiency, the inclusion of multiple subjective evaluation items, and the irrationality of the weight for each evaluation item are continue to be presented. The central office group, the local government, the relevant industry, and the expert group share recognition, but the solution is not derived. Hence, the major evaluation items to be improved were derived with the characteristics analyzed to secure the objectivity of the construction evaluation. For the analysis method, the standard deviation and the Fleiss Kappa analysis method were used by utilizing the characteristics that the construction evaluation criteria consist of all 4-point measures (good, average, insufficient, and poor). According to the result, the 10 evaluation items of the total 25 construction evaluation items were derived as the evaluation items to be improved. It was found in the analysis on the major characteristics of the derived evaluation items that the qualitative evaluation criteria such as 'Very Suitable' and 'Suitable' were commonly included in the detailed evaluation guidelines. Hence, as far as the future construction evaluation standards are concerned, the qualitative evaluation standards are sublated, and the improvement should be made mainly for the quantitative evaluation criteria enabling the objectivity assurance.

This study was conducted to improve the classification schemes of KDC in the fields of motion picture materials. Classification schemes of the KDC, DDC and LCC for motion picture materials were analyzed and compared. From the results, KDC was found to be the least suitable classification system to handle motion picture materials because it had very poorly detailed subdivisions of items and incomplete subsidiary tables to develop some subject items to represent various aspects of motion picture fields. Some suggestions to cover the deficiencies of KDC for motion picture fields were made in terms of 9 subdivisions and 53 sub-items. Particularly, new subdivisions of ‘types of genre', ’motion picture festival', 'worldwide motion pictures' and ’people related to motion pictures' were added.

This study analyzed faculties' perceptions on the importance and performance of effective teaching behaviors. The effective teaching behaviors scale consisted of 40 items belonging to 8 factors. A survey was conducted with 86 faculties from 2 universities. It was found that the differences between the importance and performance levels of all items except for 'applying emphasis on important contents' were statistically significant. The scores of importance were higher than those of performance. The results of the IPA showed that 'keep up the good work' area included 19 items that those were high the scores of importance and performance. The 'concentrate here' area included 5 items that need to be improved for effective teaching. The first priority items needing to be improved were 1) Establishing instructional methods and strategies suitable for the objectives, 2) establishing clear objectives, appropriate examples and systematic classes, 3) providing questions, opportunities and appropriate feedback. We suggested that a faculty development program needs to be developed for effective teaching.

본 논문은 전체 데이터베이스에서 일부 추출된 샘플 데이터에서 빈발항목 집합을 찾는 연관규칙 마이닝 알고리즘을 기술한다. 샘플링기술을 이용하면 마이닝과정에서 필요한 데이터베이스의 접근 양을 줄이므로써 실행시간을 단축시킬 수 있다는 장점이 있지만, 전체데이터베이스를 이용한 마이닝보다 정확도가 떨어진다는 단점이 함께 존재한다. 이전의 Chen의 FAST알고리즘은 샘플링을 이용한 마이닝과정에서 거리오차함수를 이용한 트리밍과정을 통해 빈발 1항목집합에 대한 정확도를 개선시켰다. 이후 IFAST 알고리즘은 트리밍과정에서 빈발2-항목집합까지 고려하여 빈발2-항목집합 이상의 빈발항목집합에서도 정확도를 개선시켰다. 본 논문에서는 트리밍과정에서 사용될 추정데이터를 여러 개의 샘플데이터를 이용하여 얻으므로써 오류항목집합(false itemset)의 수를 줄이고 전체적인 정확도를 향상시키는 새로운 알고리즘을 소개한다.

The addition and evaluation of health impact items in Environmental Impact Assessment document are written in hygiene and public health items only for specific development projects and are being reviewed. However, after the publication of the evaluation manual on the addition and evaluation of health impact items in 2011, there is a demand for continuous methodology and improvement plans despite partial improvement. Therefore, in order to propose a methodological improvement of the evaluation manual, this technical paper identified detailed improvement requirements based on the consultation opinions on hygiene and public health items, and investigated and suggested ways to solve this problem by reviewing the contents of the research so far. As for the improvement requirements, the contents related to mitigation plan, post management, effect prediction, assessment, and present-condition investigation were presented in Environmental Impact Assessment documents for the entire development project at a frequency of 93%, 85%, 80%, 74%, and 67%, respectively. Particularly, the detailed improvement requirements related to mitigation plan consisted of an establishment direction and a management of development project. Considering the current evaluation manual and the frequency of improvement requirements, this paper proposed concrete methods or improvement plans for major methodologies for each classification of hygiene and public health items. Furthermore, a comprehensive evaluation methodology related to whether a project is implemented was proposed, which is not provided in the current assessment manual.

This paper reports on three Delphi surveys based on draft evaluation items with the aim of deriving evaluation items prior to developing a BF certification index for school facilities in order to make the index safe and convenient. To this end, problems were formulated using content analysis and follow-up evaluation of existing BF certification indicators. Draft BF certification evaluation items for school facilities were proposed. The adequacy of each evaluation item was verified using a Delphi survey. Experts and working-level groups, such as university professors, architects, public officials, certification agencies, and organizations for disabled persons, provided feedback for all evaluation items for school facility BF, which was incorporated in the final evaluation items. As a result of the Delphi surveys, in addition to the existing 8 evaluation items, a total of 75 evaluation items were proposed as maintenance items, 12 as improvement review items, and 15 as new evaluation items.
