Nowadays worldwide leading companies try to establish more efficient and comprehensive management system for getting high quality, reliability and safety. In this paper, we investigate standards for quality management, dependability management and risk management. We also suggest an integrated and comprehensive system of quality(ISO/TS16949), dependability (IEC60300)and risk(JIS Q2001). The evaluation method on the performance of dependability management systems are developed and applied for the semiconductor equipment company.

For high performance Grid environments, an efficient GIS(Grid Information Service is required In the Metacomputing Directory Service(MDS) of the Glogus middleware, the Lightweight Directory Access Protocol(LDAP), which is a distributed directory service protocol, is used. The LDAP GIS differs from general purpose LDAP directories in that most of the LDAP operations are write in Grid environments. To get an efficient design of the GIS, it is thus required to analyze the performance of the LDAP system in the context of Grid environments. This paper presents the result of a performance analysis of LDAP systems. The main objective of the evaluation is to see the performance scalability of the LDAP system in the Grid environment where the write operations prevails. Based on these results, we suggest directions of an efficient LDAP-based GIS for a high performance Grid.

This study was conducted to test the effect of Burns' cognitive-behavioral group counseling on depression and anxiety of industrial high school students. For this purpose, an experimental group and comparative group which was composed of 15 students respectively were assigned. The independent sample t-test between experimental group and comparative group about the degree of pre-test and after-test and the opposition sample t-test within each experimental group and comparative group were conducted. Analysis of Covariance was also applied. Results of the analyses showed that Burns' cognitive-behavioral group counseling program was effective in decreasing depression and anxiety. Implications of these results on student guidance and counseling were discussed. Suggestions for future research were presented and limitations were indicated.

The primary objective of this study is to firstly survey and analyze the working environment and actual condition, secondly know their problems, and then provide the basic data about how to improve their working conditions. The specific study items for getting the goal above is as follows: 1. How does the industrial company connect with highschool vocational education well? 2. How does the mechanical technical highschool graduate apply with industrial field? The result of study is as follows: 1. In case of employment's information and the industrial educationed cooperation, the workers who has the working history in less than 5 years takes short to find the job. National high school graduates and those who get the job through the school and the teacher changed their job at short period compared to other. 2. There was no benefit about the same major's worker at industrial field. The workers admitted that there is the exemption fo military service and the certification's allowance, only for which is related to their job. The longer the workers stay their job, the more they had the chance to get the exemption of military service. National highschool were carried out the curriculum well as planed especially for their major subjects. Whereas, the public and private highschools weren't. The seniors of their job and the coworkers are very helpful for learning the actual knowledge. The workers said that the school's curriculum and club activity weren't effective applying with their working field. 3. The study says that the important things of their job is the knowledge of their major. Those who 80% answered that the worker must improve the knowledge of their major to be a good engineer. Learning from their senior in working field was very helpful. The question above was ranked as the first. 4. The answer says that the new changed job's pay is more than the previous job. That is, the reason of leaving the job is the pay gap. The most dissatisfaction and problems in present job was the environment of working and the working condition. 5. Regarding to asking next year's plan, the answer says that keeping the job was ranked as the first. That answer means that they conservative.

Purpose: The purpose of the study was to develop educational materials on field practice safety based on existing field practice data and accident cases regarding vocational high schools and apply them to identify their impact. Methods: The existing data, accumulated since 2010, on field practices of vocational high schools were analyzed, and educational materials regarding field practices were developed by six experts. 195 students in three vocational high schools were surveyed before and after being taught with the materials. The survey asked about their knowledge of industrial safety and health and attitudes toward industrial safety and health. Results: As a result of the study, harmful environments for field practices of vocational high schools were physical, chemical, ergonomic, and emotional labor, and the consequences were accidents, death by overwork, musculoskeletal diseases, etc. The materials covered students' rights and how to respond to workplace accidents in the 1st round, how to organize a workshop in the 2nd round, workplace safety and health signs in the 3rd round, prevention of musculoskeletal diseases in the 4th round, management of physical risk factors in 5th round, management of hazardous chemicals in 6th round, wearing and managing protective equipment in 7th round, first aid depending on the situation in the 8th round, CPR and defibrillator in the 9th round, sexual harassment in the 10th round, and prevention of sexual violence in the 11th round. After completing the education, their knowledge of industrial safety and health increased significantly from 6.52 points to 7.01 points. Conclusion: The results of this study suggest: first, to statistically organize the data on accidents that have occurred during field practices of vocational high schools; second, to develop a systematic curriculum for high school 1st to 3rd graders on accidents that may happen during field practices of vocational high schools.

The growing interest in the application of arachidonic acid (ARA) in various fields of health and dietary requirements has elicited much attention on the industrial production of ARA-containing oil by the cultivation of Mortierella fungi. For the industrial production of ARA, various studies, such as isolation of a high-potential strain and optimization of culture conditions, have been conducted. Studies including the investigation of morphology are important because ARA is accumulated in the mycelia, and thus cultivation with high biomass concentration is essential for obtaining a high ARA yield. Combining the results derived from various studies, a high ARA yield was attained in an industrial fermentor. These ARA production techniques are applicable to the production of other polyunsaturated fatty acids (PUFAs), and will contribute to the improvement of fermentation technology especially in the field of fungal cultivation.

이 연구의 목적은 창의적 체험활동의 하위 영역인 동아리활동에 대한 공업계 고등학교 교사들의 인식을 조사하여, 향후 공업계 고등학교의 특성에 맞는 창의적 체험활동을 할 수 있도록 바람직한 방향을 제시하는데 필요한 기초 자료를 제공하는 것이다. 이 연구의 응답자는 전국의 공업계 고등학교에 재직 중인 교사 393명이고, 동아리활동에 대한 5개 영역 32개 분야의 문항(중요도, 반영도)으로 구성된 설문지를 활용하였다. 연구의 결과는 다음과 같다. 첫째, 동아리활동 영역에서 중요도 분석 결과, '학술 활동'은 '발명', '문화 예술 활 동'은 '영상예술', '스포츠 활동'은 '도전활동', '실습 노작 활동'은 '학교 특성화 전공', '청소년 단체 활동'은 '스카우트연맹'과 '청소년적십자'가 가장 높게 나타났다. 둘째, 동아리활동의 영역에서 반영도 분석 결과 '학술 활동', '문화 예술 활동' 및 '스포츠 활동' 영역은 대체적으로 공업계 고등학교 교사들이 생각하는 중요도에 비슷하게 반영되고 있었다. 하지만 '학교 특성화 전공'을 제외한 '실습 노작 활동'과 '청소년 단체 활동'의 경우는 중요도와는 별개로 모든 분야가 잘 반영되지 않고 있는 것으로 나타났다. '실습 노작 활동'은 중요도 분석과 반영도 분석이 비슷하게 나타났지만 '청소년 단체 활동'은 중요도에 비해 반영도 값이 현저히 낮게 나타나 중요도와 반영도에 큰 차이가 있었다.

The vector wave equation is widely used in electromagnetic wave analysis. This paper solves the vector wave equation using curl-conforming finite elements. The variational problem is established from Riesz functional based on vector wave equation and the unique existence of weak solution is explored. The edge elements are used in computation and the simulation results are compared with those obtained from a commercial simulator, ANSYS HFSS (high-frequency structure simulator).
