A reliability approach to evaluate structural performance has gained increased acceptability and usage over the past two decades. Most reliability analyses are based on the reliability of an individual component without examining the entire structural system. These analyses often result in either unnecessary repairs or unsafe structures. This study uses examples of series, parallel, and series-parallel models of structural systems to illustrate how the component reliabilities affect the reliability of the entire system. The component-system reliability interaction can be used to develop optimum lifetime inspection and repair strategies for structural systems. These examples demonstrate that such strategies must be based on the reliability of the entire structural system. They also demonstrate that the location of an individual component in the system has a profound effect on the acceptable reliability of that component. Furthermore, when a structure is deteriorating over time, the reliability importance of various components is a1so changing with time. For this reason, the most critical component in the early life of the structure may not tie the most critical later.

After UNECD(United Nations Conference of Environment and Development) in 1992, ESSD (Environmental Sound and Sustainable Development) is an important concept of urban planning in Korea. The introducing environmental assessment system of urban planning and the district unit planning system were representative cases. In this process, Landchaftplanung(ecological landscape planning) was introduced from Germany. This study was executed for applying ecological landscape planning to Eunpyung New Town in Seoul city, and analyzing the problem to apply this system. The process of ecological landscape planning was followed to (1) the site survey, (2) the analysis and assessment of survey data, (3) the establishing ecological landscape planning. Three master architects participated in all investigations. The major fields of them were landscape architecture, architecture, and urban planning. Master Architects helped many aspects. In conclusion, ecological landscape planning was feasible to be applied to develop other New Town in Korea. However the mediation system is very weak, if different situations are confronted with ecological landscape plan and land use plan in the operative legal framework of Korea. Thus, the legislation of mediation system is necessary for an establishment of ecological landscape planning.

In this paper, we propose an automatic cosmetic foundation recommendation system that suggests a good foundation product based on the user's skin color. The proposed system receives and preprocesses user images and detects skin color with OpenCV and machine learning algorithms. The system then compares the performance of the training model using XGBoost, Gradient Boost, Random Forest, and Adaptive Boost (AdaBoost), based on 550 datasets collected as essential bestsellers in the United States. Based on the comparison results, this paper implements a recommendation system using the highest performing machine learning model. As a result of the experiment, our system can effectively recommend a suitable skin color foundation. Thus, our system model is 98% accurate. Furthermore, our system can reduce the selection trials of foundations against the user's skin color. It can also save time in selecting foundations.

We investigated the major trends in health aid financing in the Democratic People's Republic of Korea (DPRK) by identifying the primary donor organizations and examining several data sources to track overall health aid trends. We collected gross disbursements from bilateral donor countries and international organizations toward the DPRK according to specific health sectors by using the Organization for Economic Cooperation and Development creditor reporting system database and the United Nations Office for the Coordination of Humanitarian Affairs financial tracking service database. We analyzed sources of health aid to the DPRK from the Republic of Korea (ROK) using the official records from the ROK's Ministry of Unification. We identified the ROK, United Nations Children's Fund (UNICEF), World Health Organization (WHO), United Nations Population Fund (UNFPA), and The Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM) as the major donor entities not only according to their level of health aid expenditures but also their growing roles within the health sector of the DPRK. We found that health aid from the ROK is comprised of funding from the Inter-Korean Cooperation Fund, private organizations, local governments, and South Korean branches of international organizations such as WHO and UNICEF. We also distinguished medical equipment aid from developmental aid to show that the majority of health aid from the ROK was developmental aid. This study highlights the valuable role of the ROK in the flow of health aid to the DPRK, especially in light of the DPRK's precarious international status. Although global health aid from many international organizations has decreased, organizations such as GFATM and UNFPA continue to maintain their focus on reproductive health and infectious diseases.

본 연구는 선진복지국가 중 독일, 스웨덴, 영국의 사회보험제도의 통합사례를 분석하였다. 제도통합과 조직통합이라는 두 가지 차원으로 나누어 세 나라의 사회보험 통합을 역사적 맥락에서 분석하였다. 독일은 여전히 제도와 조직이 분리되어 있고, 사회보험의 적용 징수업무를 질병보험조합이 담당하고 있다. 영국은 제도와 조직 모두 통합되어 있고, 적용 징수업무를 국세청이 담당하고 있다. 스웨덴은 사회보험체계가 각각의 제도별로 구분되어 있지만 운영기관은 통일되어 있고, 적용 징수업무를 국세청이 담당하고 있다. 본 연구는 이러한 선진국 사회보험 통합의 역사적 발전경로에 대한 고려를 바탕으로 한국 사회보험제도가 이제까지 걸어온 과정에 비추어 2011년부터 시행되고 있는 사회보험료 징수업무 건강보험공단 이관이 적절한 선택이었는지를 평가하였다.

UAE(United Arab Emirates) 원전(원자력발전소)의 수출을 목적으로 UAE, 미국, 일본, 한국의 원전 화재방호규정을 상호 비교 검토하였다. UAE를 포함하여 미국, 일본의 원전 화재방호규정은 화재하중에 따른 화재위험도 분석결과에 따라 소화설비를 설치하도록 규정하고 있다. 반면, 우리나라는 소방관계법에서 원전을 발전시설로 구분하고 있으나, 원자력법에서는 원자로 및 관계시설로 분류하고 있고, 각 법률간 화재방호 설계기준도 상이하다. 앞으로 우리나라가 원전 수출국의 지위를 계속적인 유지하기 위해서는 화재 위험도분석의 결과가 설계에 반영될 수 있어야 한다. 결론으로, 국내 소방관계법이 원전의 특수성을 반영하기 위해서는 소방시설공사업법 시행령 제2조 2항의 성능위주설계를 해야 할 특정소방대상물에 원전이 추가되어야 함을 제안하였다.

본 논문에서는 스프링클러설비가 설치된 대상물에서의 화재발생 시 인명피해 발생통계를 통하여 화재안전기준 요소의 성능을 분석하고 국내 화재안전기준 요소와 미국의 NFPA 13의 기준과의 비교를 통하여 성능을 분석함으로써 합리적이고 공학적인 화재안전기준 제정으로 인명 및 재산피해를 감소시킬 수 있는 개선방안에 대하여 연구하였다. 미국의 경우 스프링클러설비가 설치된 경우가 설치되지 않은 경우에 비하여 화재 당 사망률이 83 % 정도 낮았으나 국내의 경우 280 % 정도로 미국의 경우보다 3.37 배 높았다. 이와 같은 소화성능의 결여는 일률적인 용도분류, 화재하중을 고려하지 않은 수원의 양, 살수밀도를 고려하지 않은 기준개수 및 수평거리에 따른 스프링클러설비의 설치가 그 원인으로 분석되었다.

In this thesis. I have first introduced and studied Chubb & Son. Inc. v. Asiana Airlines. 214 F.3d 301 (2nd Cir. 2000). which held that at the time that the dispute in this case arose. there was no treaty relationship between the United States and South Korea under the Original Warsaw convention. the Hague Protocol. or a treaty consisting of those provisions of the Original Convention that were not amended by the Protocol. And I have analyzed U.S. government s position that was expressed in Brief for the United States as Amicus Curiae on petition for a writ certiorari to the 2nd Circuit on Chubb & Son case and 2nd Circuit s Fujitsu Limited v. Federal Express Corporation. 247 F.3d 423 (2001) which was held in a related question afterwards but was somewhat inconsistent with Chubb & Son s holding. Furthermore. I also examined U.S. government s measures which have been considered and taken to cope with consequences of Chubb & Son case's ruling. Lastly. I have examined several effects which Chubb & Son s ruling would give our nation s airlines and suggested our government's countermeasures.

Many biobanks were established as biorepositories for biomedical research, and a number of biobanks were founded in the 1990s. The main aim of the biobank is to store and to maintain biomaterials for studying chronic disease, identifying risk factors of specific diseases, and applying personalized drug therapies. This report provides a review of biobanks, including Korean biobanks and an analysis of sample volumes, regulations, policies, and ethical issues of the biobank. Until now, the top 6 countries according to the number of large-scale biobanks are the United Kingdom, United States, Sweden, France, the Netherlands, and Italy, and there is one major National Biobank of Korea (NBK) and 17 regional biobanks in Korea. Many countries have regulations and guidelines for the biobanks, and the importance of good management of biobanks is increasing. Meanwhile, according to a first survey of 456 biobank managers in the United States, biobankers are concerned with the underuse of the samples in their repositories, which need to be advertised for researchers. Korea Biobank Network (KBN) project phase II (2013-2015) was also planned for the promotion to use biospecimens in the KBN. The KBN is continuously introducing for researchers to use biospecimens in the biobank. An accreditation process can also be introduced for biobanks to harmonize collections and encourage use of biospecimens in the biobanks. KBN is preparing an on-line application system for the distribution of biospecimens and a biobank accreditation program and is trying to harmonize the biobanks.
