The major purpose of this article is to analyze Lee Jema's idea of 'cultivating the self,' and therefore reveal a difference between his idea and 'cultivating and nurturing (the mind)' shown in traditional medicine and Neo-Confucianism. For this purpose, I first analyzed 'cultivating and nurturing (the mind)' of traditional medicine and Neo-Confucianism and showed Lee Jema's originality by studying philosophical foundations of Sasang constitutional Medicine. The idea of 'cultivating and nurturing (the mind)' is transcendental in that it pursues the unity between humans and the principle of natural changes or the Heaven. However, Lee Jema developed his own medical theory by analyzing an ontological structure of human beings and nature and life, and reinterpreting four beginnings on the basis of experience. He reinterpreted humans as a being in the structure of time and space, and relationships with others. In addition, he reinterpreted nature and life and four beginnings as the capability of wisdom and action and the function of mind and body. Therefore, he tried to overcome a transcendental thinking to aim for the unity of humans with the Heaven. Also, he discovered that the most important reason for disease is biased emotions (moral/private) because biased emotions influenced the function of mind and body. The causal relationship is the basis of his medical theory. Therefore, his idea of cultivating the self is focused on being careful not to make emotions biased. This reveals that even though Sasang constitutional theory came from the traditional medical theory and Confucian morality, it developed on a different philosophical foundation. In this regard, I tried to differentiate Lee Jema's idea of cultivating the self from 'cultivating and nurturing (the mind)' which aims for the unity between humans and the principle of changes or the Heaven.

One of the most lasting and influential projects for radical reform of Korean universities is a discourse on networking national and public universities. The discourse, proposed with a level equalization of universities as its ideological basis has raised various discussions and suggestions in the past 20 years. It was proposed as a fundamental solution to the 'disastrous' hierarchical structure of universities and 'hellish' entrance exam competition. This paper aims at reexamining the efficacy of its ideological proposition and its practicability at the present time in reference to such foreign cases, which have worked as model cases for this discourse: the reformation of the University of Paris and the California master plan for higher education in the 1960s. The two different contexts, however, should be considered in applying the cases to Korean university reform. 1) The foreign cases of united universities were formed 'naturally' in the expanding phases of higher education while the Korean project pursued 'artificially' in the midst of reconstructing process. 2) The foreign cases had an overall influence on education in general as most of the universities in those countries were public or national, while the effect of Korean project will be very limited as most of the university students attend private universities. Besides those differences, the new situations surrounding universities such as globalized competitiveness and technological innovation is making the idea of standardization of universities obsolete. Korean university reform should not be centered on the integration of universities but on their characterization and enhance the specific strengths of each group of universities.

Background: Results on the action of antioxidants in extracts of Equisetum hyemale stems and roots have already been reported, but the antioxidant properties have not been analyzed. Purpose: This study was to determine the molecular structure of antioxidants in substances extracted from E. hyemale stems and roots. Methods: Component analysis was analyzed by HPLC and LC-MS after extraction with hot water and ethyl alcohol. Results: The HPLC chromatogram of stem and root extracts showed four significant peaks at a wavelength of 205 nm. Peak 1 at 280 nm is a typical simple phenolic type, and both peaks 2-4 near 280 nm and 370 nm are typical flavonoid glycosides. As for the antioxidant level of the extract by HPLC analysis, the sum of the peaks at 740 nm was the highest at 3,669 mAU in the 100% ethanol extract, 3,096 mAU in the 70% ethanol extract, and 2,868 mAU in the hot water extract. As a result of LC-MS analysis of the antioxidant extract, kaempferol-3-sophoroside-7-glucoside with a molecular weight of 772 da at peak 3, and kaempferol-3-sophoroside-8-glucoside with a molecular weight of 788 and 772 at peak 4 was identified. Conclusions: The above results show that two types of antioxidants were identified in the antioxidant extract of E. hyemale exrtracts. Therefore, the potential as a raw material for functional cosmetics has increased.

상이한 자연현상으로 발생된 자료들은 때때로 통계적으로 다른 특성을 가지는 경우가 있다. 이런 자료들은 다른 두 개 이상의 모집단에서 자료가 발생한 것으로 가정할 수 가 있다. 기존에 널리 사용되어온 분포형 모형의 경우 단일한 모집단으로부터 자료가 발생한다는 가정하에서 개발된 모형들로 위에서 언급한 자료들을 적절히 모의할 수 없다. 이런 상이한 모집단에서 발생된 자료를 모형화 하기 위해서 혼합분포모형(mixture distribution)이 개발되었다. 홍수나 가뭄 등과 같은 극치 사상의 경우 다양한 자연현상들로부터 발생하기에 혼합분포모형을 적용할 경우 보다 정확한 모의가 가능하다. 혼합분포모형은 두 개 이상의 비혼합분포모형들을 가중합하여 만들어진다. 혼합 분포모형의 형태로 인하여 기존의 분포형 모형의 매개변수 추정 모형으로 널리 사용되던 최우도법 (maximum likelihood method), 모멘트법(method of moment), 확률가중모멘트법 (probability weighted moment method) 등을 이용하여 혼합분포모형의 매개변수를 추정하는 것이 용이 하지 않다. 혼합분포모형의 매개변수 추정 방법으로는 Expectation-Maximization (EM) 알고리즘, Meta-Heuristic Maximum Likelihood (MHML) 방법, Markov Chain Monte Carlo (MCMC) 방법 등이 적용되고 있다. 현재까지 수자원 분야에서 사용되는 극치 자료를 혼합분포모형을 이용하여 모의할 때 매개변수 추정방법에 따른 특성에 대한 연구가 진행되지 않았다. 본 연구에서는 우리나라 연최대강우량 자료를 이용하여 혼합분포모형의 매개변수 추정방법 (EM 알고리즘, MHML 방법, MCMC 방법) 들의 특성들을 비교 분석하였다. 혼합분포모형으로는 Gumbel-Gumbel 혼합분포 모형을 적용하였다. 본 연구의 결과는 향후 혼합분포모형을 이용한 연구에 좋은 기초자료로 사용될 수 있을 것으로 판단된다.

A general purpose of 4-node co-rotational resultant shell element is developed for the solution of nonlinear problems of reinforced concrete, steel and fiber-reinforced composite structures. The formulation of the geometrical stiffness presented here is defined on the mid-surface by using the second order kinematic relations and is efficient for analyzing thick plates and shells by incorporating bending moment and transverse shear resultant forces. The present element is free of shear locking behavior by using the ANS (Assumed Natural Strain) method such that the element performs very well as thin shells. Inelastic behaviour of concrete material is based on the plasticity with strain hardening and elasto-plastic fracture model. The plasticity of steel is based on Von-Mises Yield and Ivanov Yield criteria with strain hardening. The transverse shear stiffness of laminate composite is defined by an equilibrium approach instead of using the shear correction factor. The proposed formulation is computationally efficient and versitile for most civil engineering application and the test results showed good agreement.

이 논문은 부산대학교 전자계산학과 인공지능 연구실에서 개발한 정보검색 시스템 "미리내"의 적합성 피드백 방법을 분석하고, 그 방법들의 검색 효율을 비교 분석하였다. "미리내"에서 질의문은 자연언어 질의문을 사용하고 재검색을 위한 적합성 피드백은 원질의문에서 검색된 문서 중 이용자가 직접 선택한 적합 문서에서 추출한다. 적합성 피드백은 크게 단어 확장(Term Expansion)을 위한 단어 선택 방법과 추가될 단어에 가중치를 부여하는 단어 가중치 부여(Term Weighting)의 2가지 요소로 이루어진다. 단어 선택을 위해서는 적합 문서에 나타난 단어 빈도합(tf), 역문헌빈도(idf), 적합 문서 중에서 해당 단어가 있는 적합 문서의 비율(r/R) 등의 정보를 이용한다. 단어 가중치 부여 방법으로는 정규화 또는 코사인 함수를 이용하여 부여하였다. 단어확장에는 tfidf가 tfidf(r/R)보다 정확도 면에서 나은 향상율을 보였으나, 30위 내 검색된 적합문서의 수를 비교해 보았을 때 tfidf(r/R)의 정확도가 높았다. 단어 선택 방법에서 계산된 값을 정규화하여 가중치를 부여하였을 때 보다 코사인 함수를 이용하여 가중치를 부여하였을 때 정확도가 높았다. 실험은 KT-Set 2.0 (4391 건), 동아일보 96 년 신문기사(70459 건)를 대상으로 수행하였다.

Heat transfer characteristics in terms of the tube wall-temperature and the enthalpy have been investigated utilizing ribbed (rifled) tubes in order to enhance heat transfer performance. Considerations were given for the cases of smooth tubes in order to compare with the case of ribbed tubes. The tilt angle of the experimental tubes are from 0.deg. to 90.deg. , in order to simulate the boiler water tubes having 15.deg.-90.deg. inclined angle in boiler nose and studded tubes (burner zones), Natural convection and forced convection (Re=1810) conditions were considered in the experiments. The experimental results for the effect for the tube inclination through a natural convection and forced convection are presented and it is shown that ribbed tubes permit an appreciable increase in heat transfer coefficients and consequently it means substantial reductions in boiler water wall tubes and heat exchanger surface areas.

도시생활과 관련된 교통 주택부문의 온실가스 배출량은 43%를 차지하고 있어 도시에서의 온실가스 저감대책 마련이 시급하며, 저탄소 녹색성장의 시대적 요구에 따라 기후변화 위기에 적극적으로 대응할 수 있는 저탄소 녹색도시 조성이 필요한 실정이다. '저탄소 녹색도시'는 지구온난화 등 기후변화의 주요 원인인 이산화탄소의 배출을 획기적으로 감축하고, 지속가능한 도시기능을 확충하면서 자연과 공생하는 도시를 말한다. 최근의 '저탄소 녹색도시'는 기존의 녹색도시와 또 다른 양상을 보이고 있다. 자원순환과 신재생에너지원의 도입을 주장하고, 탄소상쇄를 위한 에너지 및 자원절감 전략을 중요시 하고 있다. 선진국에서는 이미 주거단지내 소비되는 난방과 전력은 단지내에서 생산되는 신재생에너지를 활용하고 있으며, 모든 주택의 지붕위에 태양광 패널을 설치하고 단지 내 열병합 자가발전소에서 산업폐기물을 소각하여 에너지를 생산함으로써 제로 에너지(Zero Energy)를 실현하고 있다. 선진국 뿐 아니라 전 세계의 이목이 '저탄소 녹색도시'에 집중되고 있으며 저탄소 녹색도시를 조성해야 하는 것은 선택이 아닌 의무가 되고 있다. 우리나라도 2020년 그린홈 100만호 보급을 목표로 주택분야 보급가능 신재생 에너지원을 태양열, 지열, 소형풍력, 연료전지 등으로 다양화하여 안정적 보급 기반을 확보해 가고 있다. 녹색도시를 조성하기 위해서는 저탄소 주택, 저탄소 에너지, 녹색교통, 생태녹지, 물 및 자원순환등 핵심요소들의 적용방안이 검토되어져야 한다. 이에 본지에서는 "저탄소 녹색도시의 해외사례와 국내 적용방향", "그린홈 100만호 보급사업 그간 성과와 발전방향", "온라인 전지자동차의 기술 개발 동향" 내용에 대하여 살펴보고자 한다.
