The objective of this research is to develop education and training systems for IS department and user department personnel, which is essential to effective implementation IT(information technology) strategies in most of organizations. In order to achieve this research objective, first this study theoretically derives six categories of education and training based on comprehensive review of the previous research, and explicates concrete items for each category. And then, with respect to each of these items, we empirically investigate the degree of necessity measured by the gap between the required level of knowledge and skills which staff members should have for effective implementation of IT strategies and the present level of them which they really have. Field survey is employed for the data collection: 270 questionnaires are distributed to the companies in private and public sectors, and 196 questionnaires are collected in useful condition and are analyzed. The findings of this research shows that six dimensions of education and training are empirically derived by factor analysis as following: (1) general knowledge for organizational overview, (2) management knowledge and skills, (3) knowledge and skills of the specific information system which IS department and user department personnel are directly involved in developing and operating, (4) knowledge and skills for strategic use of IT, (5) general knowledge and skills for IT and (6) advanced expert knowledge and skills for specific IT. And the degree of necessity turns out to be statistically significantly different among six dimensions of education and training needed by IS department and user department personnel respectively. Also for each dimension, the degree of necessity is shown to be statistically significantly different between IS department and user department personnel The results of this study can provide the theoretical basis for constructing the IT education and training system for effective implementation of IT strategies, Also they can be used as a practical guideline in developing and promoting specific IT education and training programs in real organizations.

Background: The program aims to enable the participants to receive oral health care with sustainability and give them the choice and prior autonomy of dental practitioners while enhancing the benefits of sustainability. The purpose of this study is to investigate the necessity, awareness, and satisfaction of the implementation of the registered dentist program for children and adolescents, and to promote the introduction of RDPCA. Methods: The survey targeted adult residents in their 20s or older who live in Seoul, an area that continuously implements the RDPCA system, especially in the cities of Cheonan and Asan Results: 79.7% were the most unaware. However, RDPCA participants were significantly more aware than non-participants. When surveying the desire to participate in RDPCA, 96.6% of the respondents said they would 'participate' in the non-RDPCA participate group. The analysis of the satisfaction level of the RDPCA received by their children indicated that 48.6% expressed their satisfaction, and 47.3% said they were healthy. There was a high percentage of people who said they would recommend RDPCA to others as well as a high rate of those who said they would continue to use RDPCA. Conclusions: The reality is that the awareness and implementation of RDPCA are low. For the development of oral health care programs for all children and adolescents in Korea, and the improvement of the satisfaction level of the dental care system, there should be an active consideration of high-quality programs and.

This research is intended to develop oral health education program that can improve quality of oral health of infants by investigating the actual condition of oral health education provided to students major in early childhood education and contents and method of oral health education that they needed. A questionnaire survey was conducted for 427 students enrolled in related departments such as the Early Childhood Education Division and the Early Childhood Education Department at five universities in Gyeongsangnam-do. Questionnaires consisted of general characteristics, awareness of oral health, presence of experience in oral health education, necessity of oral health education, preference for oral health education method, oral health education contents. The collected data were analyzed by SPSS(Statistical Package for the Social Science) Ver 20.0. 1. Presence of experience in oral health education based on the general characteristics showed statistically significant differences only concerning the 'school system' and the 'school year' (p<0.05), and subjective awareness of oral health based on the presence of oral health education experiences showed statistically significant differences concerning the 'interest in oral health' and the 'importance of oral health' (p<0.05). 2. Necessity of oral health education based on the subjective awareness of oral health showed statistically significant differences concerning the 'interest in oral health' and the 'importance of oral health' (p<0.05). 3. Necessity of oral health education based on the preference for oral health education method showed statistically significant differences concerning the 'intention to participate in oral health education' and the 'oral health education cycle' (p<0.05). 4. The most necessary information for oral health education is proper toothbrushing method 4.24, cause of tooth decay and prevention method 4.13, helpful food and poor food for tooth 3.97, toothbrush selection and storage method 3.85. Fluoride application and fissure sealant were lowest 3.38. As a result of this research, necessity of oral health education was large regardless of general characteristics, experience in oral health education, subjective awareness of oral health, and preference for oral health education. Also the more the 'interest in oral health' in 'subjective awareness of oral health', the more the 'necessity of oral health education' and 'intention to participate in oral health education'. Therefore it is necessary to develop systematic and repetitive oral health education for students major in early childhood education.

Bridge displacement measurement system using image processing is developed to overcome the contact type system inefficiencies such as heavy, expensive property and temporary construction necessity. The system is composed of tablet PC with IEEE1394 digital camera, telescope lens and a designed target mark. The key is projection algorithm where all pixels are added up for each row(column) to find out the center line. The experimental results are shown compared with a contact type system.

Ship system is very complicated. Machine in ship system are in close connection with each other, so one is affected by others. Thus, person who want to be a marine engineer have to study not only each machine but also their relationship. For this, intelligent diagnosis system for advanced education is necessity. In this paper, AMS and failure diagnosis system is developed by using LabVIEW, G programming language.

이 연구의 목적은 마이스터고의 교육 경쟁력을 강화하기 위한 학제 개편 방향을 탐색해 보는 것이다. 구체적으로는 첫째, 중등단계 직업교육의 학제 개편과 관련한 기존의 논의를 검토하여 마이스터고의 교육 경쟁력 강화에 초점을 맞춘 학제 개편안을 제시하고, 둘째, 이에 대한 관계자 인식 분석을 실시하여 마이스터고 학제 개편 방향 설정과 관련한 주요 시사점을 도출하고자 하였다. 이를 위해 먼저 중등단계 직업교육 학제 개편 관련 선행연구 분석을 토대로 (1) 학점제 도입, (2) 3학기제 도입, (3) 수업 연한 확대를 기본 틀로 하는 마이스터고 학제 개편안을 마련하였다. 다음으로 이러한 마이스터고 학제 개편안에 대한 관계자 인식 분석을 위해 마이스터고 교원 138명 및 마이스터고졸 취업자 185명을 설문조사를 실시하였다. 또한 산업체 현장의 의견 수렴을 위해 마이스터고에 대한 이해도가 높은 산업체 인사 4명을 선정하여 FGI를 실시하였다. 조사 내용은 '학제 개편의 필요성', '학제 개편안에 대한 인식', '학제 개편안 적용에 따른 기대효과' 등으로 구성하였으며, 설문조사 분석 결과 제시를 위해 빈도, 백분율, 평균 및 표준편차 등의 기초통계 분석을 실시하였다. 분석 결과, 첫째, 마이스터고 교원 및 마이스터고졸 취업자 모두 마이스터고 학제 개편의 필요성에 대해 동의한다는 응답이 비중이 더 높은 것으로 나타났다. 둘째, 제시된 마이스터고 학제 개편안의 도입 필요성에 대해 전반적으로 일정 수준 이상 필요한 것으로 나타난 반면, 적용 가능성에 대해서는 도입 필요성에 비해 전반적으로 다소 낮게 인식하고 있는 것으로 나타났다. 셋째, 산업체 인사들의 경우, 특히 수업 연한 확대에 따른 전공심화과정의 운영에 대해 긍정적인 반응을 보였다. 이러한 분석 결과를 토대로 '보다 체계적인 학제 개편 운영 모형 설계 및 이에 따른 정책적 지원 방안 마련', '추후 학제 개편안 적용 시, 시범 적용을 통한 전면적 확대 검토', '학제 개편안에 대한 산업현장 전문가 대상 체계적인 의견 수렴' 등을 제언하였다.
