In the modernization process of the city, urbanization raised a variety of social issues. Urbanization brought noticeable changes in dwelling patterns, such as drastic changes in the housing lifestyle, that revolved around the metropolitan areas of Seoul and Busan etc. before and after the expansion of economic growth. Especially in 1985, when 23.8% of the country's population was concentrated in Seoul, the imbalance of housing supply and demand caused a vast range of housing shortage. The shortage, that resulted from public sector mishandling of natural housing demand, lead to the occurrence of private sector rental housing. The occurrence of this abnormal rental housing supply, became a major cause of Korea's typical lease system called 'Co-dwelling', where the leaseholder and tenant physically lives in the same residence. The leaseholder and tenant's 'Co-dwelling' started from partial renting of traditional Korean-style housing and transformed with the transition of dwelling form and time. However, after 1985, legalization of multi-family housing, Korean rental housing started to be planned in the beginning of it's housing construction and to be produced as an independent space with separate circulation. Also in terms of facility, it changed from partial renting of a space within the residence to an assembly of small individual spaces. However, the background of this deep-rooted 'Co-dwelling' lease system, in different forms and periods of residence, is still based on the lack of public sector rental housing supply and private sector supply of rental space to utilize extra space, 'Jeonsei' payment.

In order to evaluate the anti-tumor and synergic effect of BoJungIkKeeHapDaeChilKi-Tang on doxorubicin, the inhibitory concentration(IC), IC50 and IC90 of single use of doxorubicin and BoJungIkKeeHapDaeChilKi-Tang with their concomitant treatment against MKN-45(Human stomach carcinoma) was observed using MTT(Microculture Tetrazolium test) assay. In addition, their anti-tumor effects were also observed in the xenograft nude mice models agianst MKN-45 cell lines. BoJungIkKeeHapDaeChilKi-Tang has only mimic direct anti-tumor effect against to MKN-45 cell lines but they were decreased general depressed signs induced by implantation of tumor cell lines and increased the total WBC and lymphocyte numbers. So, it is considered or expected that BoJungIkKeeHapDaeChilKi-Tang extracts were reduced by the critical toxicity of doxorubicin and shows favorable synergic effect with doxorubicin and BoJungIkKeeHapDaeChilKi-Tang extracts.

이윤희,김홍기,Lee, Yun-Hee,Kim, Hong-Gie 한국통계학회 2008 Communications for statistical applications and me Vol.15 No.4

본 논문에서는 변이계수에 대한 영향함수를 유도한다. 경험적 영향함수와 표본영향함수를 이용하여 유도된 영향함수의 타당성을 입증하고 이를 위하여 정규분포 $N(20,1^2)$와 $N(20,5^2)$에서 각각 확률표본을 추출하여 시뮬레이션을 수행한다. 시뮬레이션 결과로부터, 유도된 변이계수에 대한 영향함수가 한 개의 관찰치가 제거되었을 때 변이계수의 변화량을 매우 정확히 추정하는 것을 확인하였다. We derive the influence function on the coefficient of variation. Empirical influence function and Sample influence function are used to verify the validity of the derived influence function. To show the validity of the influence function, we carry out simulations with random samples from normal distribution $N(20,1^2)$ and $N(20,5^2)$, respectively. The simulation result proves that the derived influence function is very accurate in estimating changes in the coefficient of variation when an observation is deleted.

In this paper a computer program was developed, which simulates the Li reduction process of PWR spent fuel, and the amount of a produced metal or chloride compound was calculated at the various amount of Li with the program. It establishes a database, which is composed of some characteristics related to a chemical reaction equation and thermodynamic data, and it calculates the transformed rate of PWR spent fuel oxide at the certain amount of Li by using the database as input data. As the results of the performance test of the program, it was validated that the transformed values of oxides, except for $Eu_2O_3$ and $Sm_2O_3$, were almost the same to within about a 6 % error with those calculated by the previous code and that the calculated amount of Li was also exactly consistent with the theoretical one, which is used for a complete reaction of each oxide in a single chemical reaction. A relationship between Li and the transformed metal of each oxide was analyzed on the basis of the quantities calculated with the verified development program. Of the results, when the amount of Li was given to be 250 mole, the 83.73 percentage of $UO_2$ was transformed into U while the remainder was still to be $UO_2$. In addition, it was appeared that the 297 mole of Li was needed to completely convert $UO_2$ into U.

Objectives : 'Pi Wei Lun' is the principal medical work of Li Dongyuan's writings, which contains most of his medical theories. There are sixty-three prescriptions in 'Pi Wei Lun', and fifty-two of them were originated from him. This study was planned to present assistance to those who apply Dongyuan's theory clinically. Methods : We investigated those fifty-two prescriptions literary, and studied them from a viewpoint of the principle and method of treatment. Results : Dongyuan's fifty-two prescriptions can be classified into eight groups from the viewpoint of the principles and methods of treatment which are composed of 'tonify the spleen and stomach & elevate the spleen Yang', 'elevate the spleen Yang & expel fire', 'elevate the spleen Yang & relieve dampness', 'promote blood flow to eliminate blood stasis', 'invigorate the spleen', 'replenish Ki & and dispel phlegm', 'purgation with drugs warm in nature', and 'the other' eight methods. Conclusions : From above, we concluded that Dongyuan considered 'the primordial energy of the spleen and stomach' as the most important when making up prescriptions, but, at the same time, he used diverse methods of treatment on the ground of differentiation of syndromes.

Residual stress is a dominant obstacle to efficient production and safe usage of device by deteriorating the mechanical strength and failure properties. Therefore, we proposed a new thin film stress-analyzing technique using a nanoindentation method. For this aim, the shape change in the indentation load-depth curve during the stress-relief in film was theoretically modeled. The change in indentation depth by load-controlled stress relaxation process was related to the increase or decrease in the applied load using the elastic flat punch theory. Finally, the residual stress in thin film was calculated from the changed applied load based on the equivalent stress interaction model. The evaluated stresses for diamond-like carbon films from this nanoindentation analysis were consistent with the results from the conventional curvature method.

‘즐거움’에 기반한 친환경 디자인 인터벤션 전략 제안

이윤희(Lee, Yun Hee),정의철(Jung, Eui Chul) 한국디지털디자인협의회 2015 디지털디자인학연구 Vol.15 No.1

미래 인류 생존의 최대 위기인 환경문제 해결을 위해 디자인 분야에서도 다양한 시도들이 있어왔다. 관련 활동을 아울러 ‘친환경 디자인’이라 하는데 동향을 살펴보면 공급 중심 접근인 친환경제품 개발과 소비 중심 접근인 디자인을 통한 행동 유도 및 인식 변화 관련 연구로 나뉘어 진행되었다. 그러나 양 측면에서 다양한 시도가 이루어졌음에도 불구하고 한계와 문제점은 여전히 남아있다. 따라서 본 연구에서는 친환경 디자인의 동향분석 및 현 시점에서의 한계점을 제시하고, 이를 타개할 수 있는 디자인 전략 방향을 제안하고자 한다. 우선 ‘친환경 디자인 인터벤션(Pro-environmental Design Intervention)’이라는 용어를 채택하고, 개념 및 범위를 정리하여 타 학문 및 디자인 내 기존 연구와의 차별점을 제시하였다. 그리고 문헌고찰 및 사례연구를 통해 감성적 디자인 인터벤션의 중요성을 강조하고, 특히 기존사례에서 주로 적용된 ‘죄책감’이 아닌 ‘즐거움’을 향후 친환경 디자인 인터벤션의 핵심 전략으로 채택하였다. 또한 디자인 단계에서의 실질적인 적용을 위해 ‘즐거움’ 감성의 유형을 분류하고 단계별로 정리한 후 제품과 서비스, 사용자 특성별로 우선적으로 적용해야 하는 전략방향을 제안하였다. 본 연구는 친환경 디자인 동향을 체계적으로 정리하고, 각 흐름의 의의와 한계점 논의를 통해 향후 친환경 디자인의 전략 방향을 제시하였다는 점에서 그 의의가 있다고 할 수 있다. There have been many attempts to resolve the environmental problems which are considered as the biggest challenges to both current and future generation. Researches on Eco-friendly Design which includes all these attempts have had two approaches in the aspects of production and consumption; Development of Eco-friendly products which focus on the production-aspect; and Research on design for cognitive change and sustainable behavior which focus on consumption-aspect. Although several attempts have been made in both sides, limitations and problems of current approach still remain. This study analyzes the trends of Eco-friendly Design, shows the limitations in current conditions, and suggests the strategy direction to resolve the limitations. In this study, the term ‘Pro-environmental Design Intervention’ is adopted and suggested the refined concept and range. It shows distinctive characteristics different from other existing design research or other fields. Also, from the literature reviews and case studies, this study emphasizes the importance of Emotional Design Intervention and considers “pleasure” a strategic point, not ‘guilt’ which is usually applied to the previous studies. It is significant that this research systematically organizes the Eco-friendly Design trends and provides a strategy direction by argument on the meanings and limitations of each trend.
