본 논문은 고주파 절연형 소프트 스위칭 PWM DC-DC 컨버터의 효율을 높일 수 있는 새로운 회로를 제안하였다. 제안한 DC-DC 컨버터는 고주파 변압기의 여자전류를 이용하지 않고 인덕턴스를 이용하였다. 그리고 고주파 절연 변압기 2차측에 동기 정류용 전력용 MOSFET에 새로운 기능을 부가한 온-오프 제어 방식을 이용하여 넓은 부하 범위에 걸쳐 안정된 영전압 스위칭(ZVS)동작을 실현하였다. 그 결과 제안한 DC-DC 컨버터의 실험 장치에 의해서 효율을 97[%]이상 달성하였다.

Purpose - The purpose of this study is to provide a formalized process of decision making for companies or organizations that need to make various decisions in the age of uncertainty. Therefore, this study aimed to proposes a strategic decision-making approach citing the relatively easily accessible using IPA(important-performance analysis) and SWOT/AHP analysis. Research design, data, and methodology - To be specific, the first step is to derive necessary attributes and conduct IPA. The second step is to subdivide the IPA results into internal strength and weakness factors and the external opportunity and threat factors, hierarchize those factors, and weight them accordingly. The third step is to build a causality model to propose a method of supporting a rational decision making. Results - The foregoing approach seems to facilitate the diversification of decision-making strategies by helping businesses or organizations to measure and analyze the attributes needed for certain decisions. Additionally, the perceived importance and satisfaction (or achievement) usage of those derived attributes can be used as the reference data for SWOT/AHP analysis. Conclusions - The proposed stepwise approach is applicable to businesses or organizations in need of making stepwise decisions in line with their retained competencies in comparison to conventional or intuitive decision-making practices.

Objective: Clinical and Experimental Reproductive Medicine (CERM) converted its language to English only beginning with the first issue of 2011. From that point in time, one of the goals of the journal has been to become a truly international journal. This paper aims to identify the position of CERM in its scholarly journal network based on the journal's metrics. Methods: The journal's metrics, including citations, countries of author affiliation, and countries of citing authors, Hirsch index, and proportion of funded articles, were gathered from Web of Science and analyzed. Results: The two-year impact factor of 2013 was calculated at 0.971 excluding self-citation, which corresponds to a Journal Citation Reports ranking of 85.9% in the category of obstetrics and gynecology. In 2012, 2013, and 2014, the total citations were 17, 68, and 85, respectively. Authors from nine countries contributed to CERM. Researchers from 25 countries cited CERM in their articles. The Hirsch index was six. Out of 88 original articles, 35 studies received funds (39.8%). Conclusion: Based on the journal metrics, changing the journal language to English was found to be successful in promoting CERM to international journal status.

본 연구에서는 한국과학기술정보연구원에서 구축중인 한국과학기술인용색인을 바탕으로 국내 주요 과학기술계 학술지에 수록된 연구 논문을 중심으로 연구자들의 인용현황을 분석하였다. 또한 기계공학 분야를 실험 대상으로 선정하여 현재 SCI의 기계공학 분야의 인용 순위와 비교한 결과 SCI의 JCR과는 실질적인 차이가 있음을 발견하였다. 본 연구는 국내 연구자에게 분야별 필수적인 연구 정보원의 제공과 국내 기관별, 분야별 과학기술 수준을 파악하고 평가하기 위한 도구로서 활용이 가능한 한국인용색인데이터베이스의 효율적인 구축방안 및 서비스모델을 제안한다.

인용분석은 원문헌에서 선행문헌들을 인용하는 현상에 근거하는 정보분석 방법이다. 인용분석과 그 응용에 대해서는 여러가지 잘 알려진 연구가 많이 있다. 이 논문은 이러한 광범위한 응용영역에 대한 검토보다, 인용분석의 사회학적 측면을 설명하고자 한다. 특히, 이 논문은 지식사회학을 연구하는 계량적 방법으로서 인용분석의 유용성을 검토하게 된다. 이를 위해, 인용행태, 인용계수, 영향요인, 인용관계 둥을 파악하는 기본방법들을 기술하였다. 그런 다음 지식사회학의 네가지 응용영역을 구분하여 제시하고 있다: (1) 지식자원의 유통, (2) 지식자원의 평가, (3) 지식공동체의 평가, (4) 지식정책적 활용. 마지막으로 이 논문은 인용분석의 한계와 결점을 인용과 인용분석 그 자체로 나누어 설명하고 있다.

영화는 이른바 집단작업을 통해 제작되는 것이 일반적이다. 그러나 디지털 시대에 들어와서는 누구나 간편하게 촬영하고 손쉽게 편집할 수 있게 되었다. 이에 따라 혼자서 제작하는 1인 제작시스템이 활성화되면서 제작 주체의 단위가 집단에서 개인으로 변화하는 경향이 생겨났다. 특히 디지털 시대가 본격화되는 90년대에 일본을 중심으로 다큐멘터리에서 무거운 정치적, 사회적 주제에서 벗어나 지극히 개인적인 소재에 눈을 돌리기 시작하면서 제작 주체와 양식의 변화, 그리고 주제도 매우 다양화되었다. 본 논문에서는 90년대 이후 본격적인 디지털 시대의 도래에 따른 다큐멘터리의 새로운 양식으로 대두된 사적 다큐멘터리의 개념과 유형, 표현양식의 특성에 대해 일본의 90년대 이후 대표적인 사적 다큐멘터리 작품을 구체적으로 예를 들며 살펴보고자 한다.

Decision Science or Decision Analysis can be described as a scientific methodolog to provide suitable quantitative information for the decision maker to be able to selected the best feasible alternative on the given decision environment and thus we can say that where there are decision problems, there needs the decision analysis to be applied to them. International shipping is generally said to be the cheapest and most widely used means of transport in international trade and each of the hundreds of seaport. So far as the decision makings in the shipping and port transportation are concerned, of real importance is to understand what the decision problems in each of shipping and port transportation really are and to recognize the meaning of relevance between shipping and seaport in the outworn phrase, that is to say, "The chain is as strong as its weakest link." This paper is intended to present a literature survey on the applied decision analysis to shipping and port transportation problems which have actually been involved in the wide variety of decision environment. At first, the author suggests four divisional framework such as decision analysis in each field of Shipping Economics, Management and Operations of Shipping, Port Economics, and Port Operation and Management, according to the main concern of the decision environment, and then the literature surveys on those four major divisions are described including the problems and solution approaches in each case. The author concludes the paper with the comment on the need of joint research around this area by citing the phrase of "a process of updating the decision makers' intuitions."s' intuitions."quot;

Purpose - The purpose of this paper is to review, analyze, and learn from the most recent cases of plagiarism and to identify and promote ethical practices in research and publication. Research design, data, and methodology - This is a case study, an analytical approach, which focuses on analyzing the most recent cases of plagiarism to identify ethical issues and concerns in journal publication practices. Results - Despite the availability of many software and web-based applications and programs to detect plagiarism, there is no universal or perfect plagiarism detection application available to ease the editorial responsibility. Lack of understanding the concept and ignorance of plagiarism were the main reasons for the cases of plagiarism. Conclusions - Some of the plagiarism cases reveal a lack of knowledge in proper application of in-text citations and references, including quoting, requiting, paraphrasing, and citing sources, etc. Furthermore, the need for recognizing and considering the distorted and falsified primary and secondary research data as plagiarism is essential to enhance ethical practices in journal publication.

This study elucidates the extra-medical citing relationship of DongUiBoGam (東醫寶鑑)'s Acupuncture&Moxibustion Chapter(ChimGu鍼灸 篇) and Acupuncture&Moxibustion Methods Chapter(ChimGu鍼灸法 篇), and based on this, tried to clarify the characteristics of the intra-medical DongUiBoGam(東醫寶鑑)'s Acupuncture&Moxibustion treatment methods. This paper is the second research result on this kind of study, and it historically investigated the original text related to Acupuncture&Moxibustion treatments in DongUiBoGam(東醫寶鑑)'s OeHyeong Chapter(外形 篇). Through this, we can see that at the time DongUiBoGam(東醫寶鑑) was compiled, UiHakGangMok(醫學綱目)'s Acupuncture&Moxibustion treatments were considered the most complete.

This study was designed to identify the purchasing practice on the bakery products by the female university students in Seoul and Kyunggi area. Total 262 questionnaires were used for the analysis among 285 responses. The results showed that 50.76% of the respondents bought the bakery products 1∼3 times a month mainly for supper or snacks. The most favored bakery products were bread, danguaja bbang, cake, pie and jori bbang, and there was a signigicant difference in the preference of bakery products by the type of dwelling (p<0.001). Students with non-food science major significantly preferred bakeries as light meals (p＜0.01). Students with food science major liked bread, jori bbang, cake and pie, but the non-food science majors liked bread, sweat red-bean bread and sandwich (p＜0.05). Depending upon the housing status and the major of the respondents, there was a signifcant difference in the purchase factor like nutrition, taste, size and sanitation of the store (p<0.05), while the purchasing frequency was not affected by those factors (p＜0.05). As to the question if there is a room for improvement, different housing status influenced significantly the respondents in citing the factors like business hours and service, and the shape of product and service(p＜0.05).
