This Study has attemped to compare the health care systems of South and North Korea. There has been a wide difference in the health care System between the South and North of Korea. In this paper, I have also shown that each health care system has its own unique response to the social, political, and economic conditions of the country. Therefore the author analyzed and summarized the important difference of health care system between the South and the North of Korea as follows. 1. Compared with the Laissez-faire health care system of South Korea, North Korea has the state socialistic health care system which provide health care services to the people free of charge. And the North Korea is marking positive efforts toward the scientification and systemization of Oriental Medicine which is called Dongui-Hak in the North-on the basis of Ju-Che idea. 2. North Korea's health care system appears to be strongly geared toward extensive and preventive treatment and launched the massive sanitary propagation campaign. which have resulted in a great success. North Korea has a system of universal comprehensive care for its population. The government has a central role in planning and regulating health care. 3. The government also employs physicians, nurses, and other professionals to provide health care to patients at public expense. In North Korea, health professionals are government employees. They work for a salary and the system is funded through general taxation. 4. In the North Korea, health services area system of the cities and countre's unit is strictly conducted along with the doctor's area responsibility system. And so without referal card, patients can not use the upper-grade medical facilities. The health care delivery system of North Korea is made up of the fourth level procedue unlike South Korea. 5. General office of Oriental Medicine, Academy of Oriental Medical Science and Guidance Bureau of Oriental Medicine are established in the organization of the Department of Health in the North Korea. And nowadays much emphasis are equally placed on the Oriental Medicine as well as Western Medicine. Both South and North Korea have faced with a critical moment of developing a mutually agreeable and acceptable system of health care for the unified nation.

This study aims to face common threats from the depletion of fish resources, the decline of production and employment as well as the increase of life risk in East Sea Rim countries, North Korea, South Korea, Japan and Russia due to the Chinese fishing fleets entering East Sea. The recent competition in fishing among fishing vessels and fleets of national origin operating in the East Sea has induced a significant change in the ecological landscape of the fishing fleets cluster while having influenced production and employment in the fishing industries of South Korea and Japan as well as life threat on the fishermen in North Korea. It seems that the population organizational ecological theory can be applied to this change. It can be seen as the isomorphism of the selection process over the exclusive economic zone (EEZ) to avoid the environment in which these North Korean fishing vessels are pushed against the Chinese fleet in the North Korean part of the East Sea. To resolve the fishery disputes or conflict in the common waters in East Sea, first of all, Chinese fishing fleets will be required to put international pressure so as to solve the unfairness of the illegal fishing and overfishing by the International Fishery Organization or the UN violations of the sanctions against North Korea selling fishing rights to China. Although it is not easy for South Korea to cooperate with North Korea in the short term, South Korea will be able to support the fishery infrastructure in North Korea in the mid- to the long-term to prevent the loss of innocent lives for their fishermen and to raise their incomes.

Nutria Myocastor coypus is one of a well known invasive riparian mammal found species around world from North America to Eurasia and Africa. In South Korea, feral nutrias inhabit areas from the Nakdonggang and Namgang (River) to their tributaries and Upo Wetland where they have had devastating effects on environment. Nevertheless, there has been little research about nutrias in Korea. This study is to analyze the genetic structure of the nutria population in the Upo Wetland and identify the origin of the source populations. Twenty individuals from the Upo Wetland were genotyped using 25 microsatellite loci. When compared with another introduced population, that of the Blackwater Nation Wildlife Refuge in U.S., the Upo population contains considerable genetic variations. Tests for Hardy-Weinberg equilibrium and Bayesian clustering analysis suggest the Upo population is genetically structured and has at least two source populations. This preliminary study presents the need for further in-depth studies about this species which should combine genetic and ecological studies.

Objective : The purpose of this study was to investigate prevalence and clinical characteristics of Post-traumatic Stress Disorder (PTSD) in North Korean defectors (NKD). Methods : The study population consisted of 300 NKDs registered in the multi-regional adaptation center (Hana Center), within three years of settling in South Korea. We conducted in-person interviews and a survey with each subject, based on the North Korean version of the WHO-Composite International Diagnostic Interview (NK-CIDI) and various clinical scales. Results : Lifetime prevalence of PTSD in NKDs was 15.3%, approximately nine times higher than South Koreans (1.7%). Although experiencing broader type of traumas with higher rate than South Koreans, NKDs revealed lower odds of PTSD in most type of trauma (p<0.05). Conclusion : NKDs are at higher risk of experiencing different types of trauma than the general population in South Korea, and it is further validated that prevalence of PTSD is also higher. Careful evaluation for comorbid psychiatric symptoms and type of traumas prior to PTSD treatment for NKDs is necessary to facilitate more appropriate intervention for each subject, according to personal experience.

Singapore, a city state with less than 6 million population, has continued successful cooperative development and become one of the most successful Asian countries in exporting expertise in urban and real estate development. This research aims to analyze Singapore's cooperative development with socialist countries including China and Vietnam from Singapore's perspective as an investor. For cooperative development projects in China, Singapore adopted Singapore-style physical urban planning concepts as well as its own institutional and administrative systems. Singapore-Vietnam cooperative development managed to acquire profitable land and diversify its portfolio in terms of industry types and rents. This made Singapore's industrial parks more competitive than other parks in Vietnam. By showcasing successful project implementation in China and Vietnam, Singapore has proved that its model for industrial park and urban development is transferable. Singapore's success in cooperative development with socialist countries provides important implications for future cooperative development between South and North Korea. For example, phased development approaches starting from individual industrial parks expanding to mixed-use townships will be very useful to realize sustainable urban planning in North Korea and reduce financial risks. Singapore dominated development opportunities in advance when socialist countries opened their economy. To pattern ourselves after Singapore, we should not only improve our relationship with North Korea but also prepare with practical components such as financing and organizational structure.

1970년 대 식용을 위한 양식을 목적으로 일본에서 도입된 황소개구리는 1990년대 초반까지 국내 하천과 호소 생태계에 큰 피해를 주었으나 최근 급속히 그 개체수가 줄어든 것으로 추정된다. 이번 연구에서는 황소개구리의 개체군 동태에 미치는 유전적 요인을 조사하기 위하여 국내에 서식하는 황소개구리의 유전자 분석을 실시하였다. 황소개구리 출현이 많은 전라남도 5개 지역에서 지역별로 채집한 개체의 미토콘드리아 ND1/tRNA 유전자 1,215 bp의 염기 서열을 결정하고 이를 기존에 발표된 황소개구리의 염기서열과 비교, 분석한 결과 모든 개체의 1개 위치에서 염기 변화가 발견되었다. 또한 조사한 개체 일부에서 유전자 염기 서열의 6개 위치에서의 변이가 발견되었으나 이는 1,215bp에서 극히 일부분이 변화된 것으로 유전적 변이가 일어 났다고 판단하기 어렵다. Kimura-2-parameter distance 분석에서 국내 서식 황소개구리는 $98.7%\sim100%$의 높은 유사도를 보여 종내 유전적 거리의 차이가 거의 없었으며 유전적으로 유사한 개체들이 cluster를 형성하는 Neighbor-Joining 분석 결과에서 원산지 황소개구리가 국내 서식 황소개구리의 일부와 함께 같은 cluster에 속하므로 원산지와 국내 서식 황소개구리는 유전적 차이가 적은 것을 알 수 있었다. 이러한 결과들로부터 국내에 서식하는 황소개구리는 종내 유전적 유사도가 매우 높으며 국내에 도입된 후 지역 특이적으로 유전적 분화가 거의 일어나지 않은 것을 알 수 있다.

Centralized hierarchical routing protocols are often used to solve the problems of uneven energy consumption and short network life in wireless sensor networks (WSNs). Clustering and cluster head election have become the focuses of WSNs. In this paper, an energy balanced clustering routing algorithm optimized by sine cosine algorithm (SCA) is proposed. Firstly, optimal cluster head number per round is determined according to surviving node, and the candidate cluster head set is formed by selecting high-energy node. Secondly, a random population with a certain scale is constructed to represent a group of cluster head selection scheme, and fitness function is designed according to inter-cluster distance. Thirdly, the SCA algorithm is improved by using monotone decreasing convex function, and then a certain number of iterations are carried out to select a group of individuals with the minimum fitness function value. From simulation experiments, the process from the first death node to 80% only needs about 30 rounds. This improved algorithm balances the energy consumption among nodes and avoids premature death of some nodes. And it greatly improves the energy utilization and extends the effective life of the whole network.

A deteriorating North Korean economy, coupled with a devastating natural disaster such as flooding and drought in recent years, brought about a severe food shortage and malnutrition problem which caused a migration of its population including young children to neighboring countries. We conducted a nutritional survey on a total of 436 children, aged 4-19 years old, who migrated to the China side of the border from July to September, 1999. The study subjects were interviewed by Korean-Chinese interviewers who were trained for anthropometric measurements and dietary surveys. Heights, weights, and chest circumference of the subjects were 70-90% of the South Korean reference values for the corresponding age and sex. Dietary intakes of the subjects were found to be extremely poor-the average number of food, mostly of plant origin, consumed in a day was 2.8, and the proportion of the subject who reported to take all three meals in a day while residing in North Korea was as low as 36.2%. Ninety five percent of the subjects had at least one clinical symptom related to malnutrition, 68.6% had 2-4 symptoms, and 15.1% had 5 or more symptoms. The results of this study provided an objective data for the first time on the severity of the food crisis and malnutrition problem that afflicted North Korean older children and adolescents as well as children aged 7 or under as previously reported elsewhere. the wasted and stunted children and youths prevailing in North Korea could exert a negative influence on the country's health and economy. More researches are needed in the future to investigate on the impact of malnutrition in North Korean children on the country's social, economic, and cultural state as well as on the health and nutrition situation.

본 연구에서는 남한과 북한의 자료를 통합하여 한반도 단위로 식량과 에너지 자원 소비량 추이를 살펴보았고, 여러 Case를 생성하여 통합 이후 한반도의 식량과 에너지 자원 소비량을 예측하고 자원 관리 방향을 제시하였다. 1990년대 이후 북한의 일인당 식량 공급량, 열량 공급량, 단백질 공급량은 모두 남한, 동아시아, 세계보다 낮으며, 동물성 식품군 공급 비중도 남한, 동아시아, 세계보다 매우 낮은 상황이다. 통합 이후 북한이 2011년 남한 수준으로 식량을 소비한다면, 2055년까지의 예상 통합 인구가 최대일 때 통합 한반도의 식량 소비량은 2011년 통합 소비량에 비해 약 25% 증가할 것으로 예상된다. 따라서 사전에 통합 이후 안정적인 식량 공급과 환경 영향 최소화를 위해 소비를 줄이고 농업 생산성을 향상시키기 위한 방안을 마련해야 한다. 북한의 에너지 소비량은 남한에 비해 매우 적으며, 지난 15년간 석탄 사용 구성비가 매우 높았다. 북한의 일인당 에너지 소비량이 2011년 남한 수준으로 증가하면, 통합 한반도의 에너지 소비량은 남한에서의 증가분을 제외하더라도 2011년 통합 한반도의 에너지 소비량에 비해 약 45% 증가할 것으로 예상된다. 따라서 에너지 소비에 의한 환경 영향을 최소화하기 위해 북한의 석탄 구성비를 줄여나가는 방향의 에너지 계획을 수립하고 에너지 설비 확충에 선진 기술 적용하는 방안을 마련해야 할 것이다.
