Background: In this study, we aimed to investigate the recent trends for health care indicators including maternal mortality ratio, infant mortality rate, under-five mortality rate, life expectancy, years of life lost, and healthcare resources in South Korea, North Korea, Germany, Russian Federation, Mongolia, Vietnam, China, Czech Republic, Poland, and Hungary. Methods: We used data from five sources: World Health Organization, Federal Institute for Population Research, World Bank, Organization for Economic Cooperation and Development health statistics, and national statistics. Results: In the early 1990s, health indicators continued to improve in countries that switched to the health insurance system, but the gap widened in North Korea as health indicators worsened. Conclusion: The establishment of a sustainable health care system after unification of the Korean peninsula requires substantial changes in the health care system and efforts to improve the health of North Koreans.

The Edwards-Vilgis slip-link theory and the Kaliske-Heinrich extended tube theory were tested experimentally using published experimental data on networks of natural and isoprene rubber and on polysiloxane networks. All parameters were adjusted to achieve an optimum fit. The data description obtained with the EV theory is not satisfactory and the parameter values tend to lie outside their reasonably expected range. But for the region of low strains, the Kaliske-Heinrich theory offers a satisfactorily accurate data description which is able to serve for practical purposes. Its crosslink term, however, is based on approximations which lead to a questionable prediction and values determined for the exponent in the entanglement term lie outside the range expected by the KH model. Thus, the title question cannot be given a positive answer. Conclusions published earlier that the trapped entanglements contribute both to the crosslink and constraint (entanglement) term are supported by the present data analysis. Experimental equibiaxial data on hydrocarbon networks do not show any maximum on their stretch ratio dependence, contrary to the predictions of molecular theories. The stretch ratio dependences of relative reduced stresses do not sensitively reflect differences in the chemical nature of the chain backbone (hydrocarbon vs. siloxane) and in the crosslinking method (end-linking vs. random crosslinking).

An experimental loop operating with water at supercritical conditions(25MPa, $600^{\circ}C$ in the test section) is designed for operation in the research reactor LVR-15 in UJV Rez, Czech Republic. The loop should serve as an experimental facility for corrosion tests of materials for in-core as well as out-of-core structures, for testing and optimization of suitable water chemistry for a future HPLWR and for studies of radiolysis of water at supercritical conditions, which remains the domain where very few experimental data are available. At present, final necessary calculations(thermalhydraulic, neutronic, strength) are being performed on the irradiation channel, which is the most challenging part of the loop. The concept of the primary and auxiliary circuits has been completed. The design of the loop shall be finished in the course of the year 2007 to start the construction, out-of-pile testing to verify proper functioning of all systems and as such to be ready for in-pile tests by the end of the HPLWR Phase 2 European project by the end of 2009.

Due to the large scale of Antarctic science, scientific collaboration is required for conducting scientific research. In this study, we attempted to investigate collaboration network and the role of research station in Antarctic science based on bibliometric data from 1995 to 2014. We confirmed that geographical proximity tends to be important for scientific collaboration by employing community detection in the network. This result raises the question about what the role of research station in Antarctica is. We tried to reveal its role by focusing on five countries, Belgium, China, Czech Republic, India, and Korea that constructed new research stations during the last decade. Relative growth rate, a value to measure the growth of publications, didn't differ much around the construction period compared to those in other periods for these countries except Belgium. However, we found geographical keywords emerged around the construction for all five countries. These keywords were utilized to observe national research activities in Antarctica. They show where countries started to be concerned about after the construction.

The criticality analysis of VVER-1000 mock-up benchmark experiments from the LR-0 research reactor operated by the Research Center Rez in the Czech Republic has been conducted with the MCS Monte Carlo code developed at the Computational Reactor Physics and Experiment laboratory of the Ulsan National Institute of Science and Technology. The main purpose of this work is to evaluate the newest ENDF/B-VIII.0 nuclear data library against the VVER-1000 mock-up integral experiments and to validate the criticality analysis capability of MCS for light water reactors with hexagonal fuel lattices. A preliminary code/code comparison between MCS and MCNP6 is first conducted to verify the suitability of MCS for the benchmark interpretation, then the validation against experimental data is performed with both ENDF/B-VII.1 and ENDF/B-VIII.0 libraries. The investigated experimental data comprises six experimental critical configurations and four experimental pin-by-pin power maps. The MCS and MCNP6 inputs used for the criticality analysis of the VVER-1000 mock-up are available as supplementary material of this article.

신 기후변화협약에 따라 전 세계적으로 온실가스를 저감하는 기술개발이 활발하게 이뤄지고 있으며, 발전·송배전 분야에서 에너지효율향상에 대한 연구가 진행되고 있다. 에너지저장장치를 이용해 잉여전기를 저장하고 전기를 공급하는 운영방식에 대한 경제성 분석, 지역단위 열 병합 발전소에서 주파수조정예비력으로 에너지저장장치를 활용하는 것이 가장 수익이 높은 운영방안으로 보고되었다. 이에 본연구에서는 체코의 열병합발전소를 대상으로 에너지저장장치 설치를 위한 경제성 분석을 실시하였다. 배터리에너지저장장치의 경제성 평가에 있어 가장 중요한 요소는 수명으로 일반적으로 1일 1회 충·방전을 기준으로 보증수명은 10~15년으로 알려져 있다. 시뮬레이션을 위해 배터리와 PCS의 비율은 1:1, 1:2로 설계하였다. 일반적으로 Primary 주파수조절용의 경우 1:4로 설계를 하지만, 열병합발전소의 특성을 고려하여 최대 1:2의 비율로 설정하였으며, 각각의 비율에 맞게 용량을 1MW~10MW, 2MWh~20MWh로 시뮬레이션을 실시하여 연간 사이클 횟수를 기준으로 수명을 평가하였다. 체코의 열병합 발전소에 배터리에너지저장장치를 설치하는 사업은 현지 인프라와 전력시장을 고려할 경우 투자 회수 기간은 3MW/3MWh가 5MW/5MWh보다 유리하다. 보조금 없이 예상 구매 가격을 고려한 간단한 투자회수기간에서 약 3년, 약 5년으로 산정되었으며, 구입비용이 전체 평생 동안 비용의 중요한 부분이기 때문에 구매가격을 50 % 낮추면 약 절반 정도의 회수 기간이 단축 될 수 있지만, 3MWh와 5MWh의 규모에 경제를 통해 수익성 확보는 불가능하다. 전력시장의 가격이 50% 하락하면 투자 회수기간은 P1 모드에서는 3년, P2 및 P3 모드에서는 2년 더 길어진다. 배터리에너지저장시스템과 발전기의 결합으로 인한 절감액의 변화에 대한 민감도 분석은 전제 범위 내에서 회수 기간에 큰 영향을 미치지 않으며, 보조금 15%를 받는 기준에서 3MW 시스템의 총 비용은 66,923,000 CZK이며, 편익은 모드에 따라 244,210,000 ~ 294,795,000 CZK이며, 비용회수기간은 3~4년이다. 동일한 기준에서 5MW 시스템의 경우 총 비용은 101,320,000 CZK이며, 편익은 모드에 따라 253,010 ~ 281,411,000 CZK로 나타나며, 비용회수기간은 5~6년이다. 체코에서 배터리에너지저장시스템은 MWh당 1년에서 1.2년의 투자회수기간이 발생하는 것을 알 수 있다.

본 연구는 비영어권 OECD 21개 국가들을 대상으로 영어능력과 경제활동(국가별 무역량, R&D투자 등), 그리고 경제 성장률과의 관계 분석을 통하여 영어능력이 국가의 경제성장에 미치는 영향을 실증적으로 규명하고자 하였다. 단순회귀분석(OLS)과 표면상무관회귀분석(Seemingly Unrelated Regression Estimation: SURE)의 기법을 사용하여 추정한 결과 체코, 핀란드, 그리고 폴란드를 제외한 여타 국가들에서는 영어능력이 직접적으로 경제성장에 정(+)의 효과를 미친다는 통계학적 유의성이 발견되지 않았다. 그러나 영어 능력은 무역량 증진의 기여를 통하여 간접적으로 경제성장에 영향을 끼치는 것으로 나타났다. 따라서 영어 능력은 경제성장에 있어서 하나의 필요조건이지 충분조건은 아닌 것으로 결론 지울 수 있다. 더불어 영어 능력은 최소한의 물적 자본과, 기술축적, 정치적 안정, 그리고 훌륭한 통치를 보완하는 충분한 보완재 역할을 담당한다면 경제성장에 긍정적인 영향을 끼칠 것이 예상된다.

The focus of this paper is to critically evaluate the contemporary health promotion policy of g Korea and Japan. The primary purpose of this comparative research project is to stimulate policy debate and to strengthen the design and implementation of evidence-based policies that improve population health and reduce health related disparities. For the purpose of the research object we adopted analysis of health promotion(HP) sources. The HP Source which is still under development in Europe, is a potentially valuable tool for global use. This European Commission funded project lead by the London School of Hygiene and Tropical Medicine has brought together organisations from all of the European Union Member States, plus Norway, Iceland, Latvia, Switzerland and the Czech Republic to contribute their data. The findings of this research will be conclude by making recommendations for further comparative studies and in particular how EUHPID and the HP Source tool and database can be expanded for use at global level through the IUHPE. The result as follows: 1. The Health Promotion Act enacted 1995 in Korea and 2000 in Japan. The government has a national document on HP titled Health Plan 2010 and Healthy Korea 2010 in Korea and Healthy Japan 21 in Japan. 2. The Health Plan 2010 of Korea contains 14 goals, i.e. life expectancy, smoking, nutrition, mental health, dental health, reproductive health, hypertension, cerebrovascular diseases, arthritis, diabetes mellitus, cardiovascular diseases, and cancer. It should be emphasized that the Korean HP national document adds 3 goals of health expectancy, reproductive health, and arthritis to its Japanese counterpart. Health Plan 2010 of Korea specifies 37 objectives in 14 goals, and Healthy Japan 21 proposes 48 objectives and 80 targets in 9 goals. 3. Health Plan 2010 and Healthy Japan 21 have not been evaluated yet, and no regular systematic monitoring reporting of HP policies is available in Korea and Japan yet. 4. National Health Promotion Fund is a financial source of HP programs at the national level in Korea. Its annual amount is 736 billion Won(equivalent to approximately 640 million US$), otherwise no specific Health Promotion Fund in Japan.
