우리나라는 에너지자원의 해외의존도가 높고 에너지다소비 산업구조를 가지고 있으며 또한 국제유가 등락에 따라 경제가 큰 영향을 받으므로 이에 대한 대처방안으로 합리적인 에너지 이용효율개선과 범국민적 에너지절약의 중요성 갈수록 높아만 가고 있는 실정이다. 에너지절약을 위하여 고효율 변압기를 채택하는 방법도 전력용변압기의 효율적 이용방안중의 하나이므로, 본 연구는 국내 전력용변암기의 평균연간 부하율을 도출하여 합리적이고 타당성 있는 고효율변압기 기술기준안 작성을 위한 자료제공을 목적으로 수행되었으며, 연구결과 도출된 내용은 국내 전력용변압기의 최저효율제 국내기준 마련 둥 변압기 관련기준안을 검토 보완하는데 활용할 수 있을 것으로 기대된다.

Purpose: This study analyzed the difference in participation motive, expectation for educational institution and educational satisfaction depending on participation level of students of advanced course for bachelor of dental technology. Methods: 81 students of advanced course for bachelor of dental technology from four university were selected by convenience sampling method. To analyzed influence of participation level depending on participation motive, expectation for educational institution and educational satisfaction, regression analysis was carried out. Results: The participation level of the students was found to be influenced by the educational satisfaction, participation motive and expectation for educational institution. Conclusion: Based on the results, it is important to understand the participation motive of the students and to offer satisfaction environment and administrative support for enhancing the expectation for education for educational institution.

A column-switching semi-micro HPLC method with fluorescence detection was developed for the direct analysis of rebamipide in human plasma. Plasma was filtered through a 0.45 $\mu\textrm{m}$ membrane filter and 5 ${\mu}\ell$ of the filtrate was directly injected onto the pre-column. After elution of the plasma proteins to waste, the retained rebamipide and internal standard(ofloxacin) were transferred to a C18 semi-microcolumn (5$\mu\textrm{m}$, 150 ${\times}$2.0mm) where they were separated using acetonitrile-1.4％ acetic acid (40:60, v/v) as mobile phase.

우리 나라의 도시생태계 평가제도는 도시계획법에 의해 시행되는 제도와 환경관련떱에 의해 시행된는 제도로 구분된다. 도시계획법에 의한 평가제도는 개발행위허가기준과 도시계획 환경성검토가 있으며, 환경관련법에 의해 시행되는 제도는 환경영향평가와 사전환경성검토가 있다. 도시생태계 평가제도는 그 동안 개발지향적인 토지이용정책으로 인해 체계적인 발달이 이루어지지 않았으며, 평가기법도 입목본수도 및 녹지자연도 등을 제외하고는 객관적인 평가기법이 개발되지 알았다. 또한 평가 결과 보전가치가 높은 지역에 대한 보전대책 및 계획과정과 사후에 대한 평가가 부족하다는 문제점을 가지고 있다 우리 나라의 도시생태계 평가제도가 활성화되기 위해서는 다음과 같은 개선방안 마련이 필요하다. (1) 비오톱지도와 같은 객관적인 도시생태계 평가기법 개발, (2) 평가결과 보전가치가 높은 지역에 대한 보전지구 지정 및 훼손에 대한 보상 방안 마련, (3) 도시개발계획과 생태계 보전계획 수립의 병행 및 사후평가 시행

Eight marine sediments from Busan port in Korea were annually analyzed to examine the concentration distribution of dioxins from 2006 to 2010. Yearly mean concentration of dioxins ranged from 186.3 to $383.3pg\;g^{-1}$ in real values and 5.087 to 8.541 pg-TEQ (Toxicity equivalency) based on dry weight of samples. The dioxin concentration at the site near fishing market was the highest concentration among all sampling sites. Also the dioxin concentration at the sites with various pollutant sources such as large ships, sewage influx and thermal power station as well as fishing market was higher than that of the sites without specific pollutant sources. Another main factor that affects the dioxin concentration is topography characteristics of the bay. The bay has relatively high dioxin concentration because of the lack of the pollutant diffusion. This study demonstrated that the dioxin concentration in the site with pollutant sources and the lack of the pollutant diffusion was relatively high as compared with the other sites. As a result of contribution ratio of dioxin congeners, OCDD (Octachlorodibenzodioxin) in all sites was major contributor in real value, in contrast, dioxin congeners in TEQ values were dominated by 2,3,4,7,8-PeCDF.

Objectives : A Survey was conducted to find out usages of Korean medicine electronic charts and requirements of clinical decision support functionalities in the charts. Methods : An e-mail was sent to about 12,000 Korean medicine doctors that was affiliated to the Association of Korea Oriental Medicine. 250 doctors answered the questionnaires during one week. Results : Most doctors of 83% answered in use the electronic charts and use it mainly to insurance claims. 46% of them felt that diagnosis functions need to be improved first in the electronic charts. Moreover, 66% of them answered that expert systems to support diagnosis is required if provided. Conclusions : The clinical decision support systems help doctors diagnosis patients in a desirable manner. Many researches have been proposed about them in modern medical science, while a few studies suggested in Korean medicine. In the future, more researches in the field of diagnosis of electronic charts should be proceeded.
