The purpose of this paper id to study the factors influencing MIS user satisfaction. For this purpose. I have reviewed the results of past studies on the performance factor of MIS, and introduced a new model associated with small & Medium Business. On the basis of this model, I have hypothesized that the following variables influence user satisfaction : (gender, age), individual characteristics(user attitude, training for user), managerial characteristic(top management involvement, organizational support) and task characteristics(task structure). There were 195 participants surveyed using questionnaires from 25 different small & medium Business in Pusan. The research model and associated hypotheses were tested by following statistical techniques: reliability test, regression, t-test and ANOVA. The findings of this study are follows; 1. It was found that gender and age are not correlated user satisfaction. 2. Among individual characteristics, only user attitude influence user satisfaction significantly. 3. While organizational supports influence positively user satisfaction, top management involvement do not influence it. 4. Task structure is highly correlated with user satisfaction. In spite of many factors affecting MIS success, this study did not consider all variables affect on user satisfaction. We need integrated model including more various factors.

산학일체형 도제학교 제도의 의사결정체계 개편 방향 탐색

안재영(Jae-Yeong Ahn),김인엽(In-Yeop Kim),김지영(Ji-Young Kim) 한국직업교육학회 2021 職業 敎育 硏究 Vol.40 No.5

산학일체형 도제학교는 고용노동부의 일학습병행을 특성화고에 적용한 것으로 고용노동부와 교육부의 협력 제도이다. 산학일체형 도제학교의 운영과 관리는 고용노동부와 산하 기관인 한국산업인력공단, 한국기술교육대학교 도제허브사업단 그리고 교육부, 시･도교육청과 한국직업능력연구원 등에서 주관하고 있다. 이러한 산학일체형 도제학교는 학생의 만족도, 학습기업의 유지율 등에서 성과를 나타내고 있다. 그러나 여러 기관에서 도제학교의 운영과 관리를 나누어 담당하여 업무 내용이 즉시 공유되지 않고 의사결정이 지연될 때가 있어 도제학교 담당자의 업무 부담이 가중되는 사례가 발생하고 있다. 이 연구에서는 산학일체형 도제학교 제도의 의사결정체계를 ‘운영･관리 체계’, ‘의사결정 절차’와 ‘관련 법과 규정’으로 구분해 문헌분석과 서면조사를 실시하였다. 연구의 주요 결과는 다음과 같다. 첫째, 산학일체형 도제학교의 운영과 관리를 위한 관계 기관들의 업무가 학생과 교사 등을 효과적으로 지원할 수 있도록 설계되기보다 이해관계에 따라 다소 복잡하게 분절되어 소통과 협력이 어려운 구조라고 볼 수 있다. 둘째, 고용노동부와 교육부를 비롯한 다양한 관계 기관들 사이에 합의와 의사결정을 위한 절차가 공식화되고 체계화되지 않은 부분이 있다. 셋째, 일학습병행법에서 산학일체형 도제학교의 운영 전반을 고용노동부 장관과 산하 기관에서 주관하도록 되어 있으나, 정부조직법에서는 학교교육에 관한 사무를 교육부 장관이 관장하도록 되어 있어 상응하지 않는 부분이 있다. 이러한 논의를 토대로 산학일체형 도제학교의 효과적인 운영과 관리를 위해 각 조직의 일부 기능 조정, 의사결정 절차의 보완과 일학습병행법의 일부 개정 등이 검토될 필요가 있음을 제안하였다. As a system applying the apprenticeship of the Ministry of Employment and Labor(MOEL) to vocational high schools of the Ministry of Education(MOE), the industry-academia partnership apprenticeship school is the cooperation system between the MOE and the MOEL. In the operation of the industry-academia partnership apprenticeship school system, many institutions are participating such as the MOEL and its affiliated organizations like Human Resources Development Service of Korea and Apprenticeship Hub Project Group of Korea University of Technology and Education, the MOE, metropolitan and provincial offices of education, and Korea Research Institute for Vocational Education & Training. However, the discussion and decision-making are not sufficiently performed between the MOE and the MOEL, which is pointed out as a problem with the industry-academia partnership apprenticeship school system. Thus, this study analyzed the decision-making system and relevant laws and regulations of the industry-academia partnership apprenticeship school system, and conducted a survey targeting the personnel related to the industry-academia partnership apprenticeship school. And the results of this study are as follows. The Act on Apprenticeship is prescribing that all the operation matters of industry-academia partnership apprenticeship school except for designation and cancellation are supervised by the Minister of Employment and Labor and its affiliated organizations. Therefore, in order to establish the decision-making system for the efficient operation of industry-academia partnership apprenticeship school, and also to reflect the participation of government agencies that need to cooperate for the operation of apprenticeship school such as the MOE and metropolitan and provincial offices of education, it would be necessary to review the partial revision of the Act on Apprenticeship.

This paper describes the optimal sizing of each component using computer simulation and presents the efficient operating scheme of series HEV using hardware simulator, the equivalent system. As the sizing method of components have been experimental and empirical, it is needed to spend much time and development cost. however, the results of computer simulation will set the optimal sizing of components in short time. There are two type of driving control, power-tracking mode and load-levelling mode, ill series HEV. This paper presents that series HEV be operated ill the load-levelling mode which is more efficient than power-tracking mode.

Ahn Jae-young(安宰永),Jo Hak-jun(趙學俊),Kim Ho-hyun(金昊顯) 대한한의학원전학회 2009 대한한의학원전학회지 Vol.22 No.2

The 『Naegyeongseupyubangron(內經拾遺方論)』, written by Nakyonggil(駱龍吉), is an ancient book of Bangron(方論). The exact time period of this book is unknown. To estimate its written time, we compared the contents of this book to other sources on the cause of diseases, the description of symptoms, the transmission of diseases, and treatments. In addition, we analyzed the features of the book by comparing it to other books of Bangron(方論). As a result, we estimated the approximate time period that it was written and gained a better understanding of the ancient medicine. We reached several conclusions through this study. 1. The approximate time period of『Naegyeongseupyubangron(內經拾遺方論)』is that of the Southern Song(南宋) dynasty of China, probably after『Saminbang(三因方)』between 1174 and 1279. 2. Nakyonggil(駱龍吉) was influenced by Wangbing(王冰), Sonsamak(孫思邈), Yuhagan(劉河間), Jinmutaek(陳無擇). and he influenced 『Uibanggo(醫方考)』. 3. The 『Naegyeongseupyubangron(內經拾遺方論)』 is the most comprehensive book among the books of Bangron(方論) because of its analysis of the 『Hwangjenaegyeong(黃帝內經)』 and its connection to the treatment of ancient diseases in Oriental Medical History.

『증보내경습유방론(增補內經拾遺方論)』에 대한 문헌(文獻) 연구(硏究)

안재영 ( Jae Young Ahn ),조학준 ( Hak Jun Jo ) 대한한의학원전학회 ( 구 대한원전의사학회 ) 2012 대한한의학원전학회지 Vol.25 No.2

Objective: Neijingshiyifanglun with additions and emendations was written by Liu Yude, a doctor who lived during Ming period. I researched the origin of the book, and analyzed the features of it as well. I also approximated his birth date and death date. In doing this, I gained a better understanding the practice of medicine in ancient China. Method: I researched the book by comparing its contents, including the causes of diseases, the descriptions of symptoms, the transmissions of diseases, and treatments, with other sources that he had referenced. Result: In understanding Hwangdineijing, Liu Yude was influenced by many medical scholars such as, Wang Bing, Ma Shi, and Wu Kun, but his opinion is most similar to that of Zhang Jiebin. In the field of the Chinese Medical Theory, he was deeply influenced by ``JinYuan-Sidaijia``s theories, particularly Li Gao and Zhu Zhenheng. In fanglun, he was greatly influenced by Yifangkao. He concluded that ``aggregationaccumulation`` was a disease of stuffiness, and suggested its cure in through ``yangjingzezichu`` and ``treatment of blood aspect``. He recognized the disease of ``reversal of qi`` as the disease of ``jiaoqi``. He also indicated that the word of ``qi`` is not ``rough`` but ``tears`` or ``yingfengliulei``. Conclusion: 1. He was an excellent medical practitioner and scholar in the history of oriental medicine. 2. He found and corrected errors in the opinions of Wang Bing, Ma Shi, and Wu Kun. 3. He frequently practiced Taipinghuiminhejijufang, and considered Spleen-Stomach, yin-blood, and fire-heat important. 4. He captured the spirit of Huangdisuwenxuanminglunfang , Neijingshiyifanglun, Yifangkao in views of remedy and theory. 5. Neijingshiyifanglun with additions and emendations is the most comprehensive book about fanglun because of its thorough analysis of the Hwangdineijing and its connection to the treatment of ancient diseases in Oriental Medical History.

공석 시 측정값을 활용한 만석 시 강의실의 음향상태 예측법

This work proposes a simple method to use the added absorption per person values to predict the expected values of the acoustical conditions in occupied classrooms. This method is based on the effects of the values of added absorption per person on the unoccupied total absorption values of the classrooms and on other room acoustical parameters. The total sound absorption in an unoccupied classroom can be calculated from measured reverberation times in the classroom. The expected occupied absorption can be calculated using equation which was obtained in a previous study (Choi, 2017) by fitting a linear regression line to a plot of total occupied absorption versus the corresponding unoccupied total absorption values measured in 12 university classrooms. The ratios of occupied-to-unoccupied sound absorption are used to predict increments in the values of acoustical parameters that result when occupants are added to the rooms.
