In recent years, reductions in infant mortality have mainly been accomplished by improving the survival of premature and low birth weight infants, however premature infants still remain at great risk. The purpose of this study was to review the maternal child health service related to premature infants and to provide a future direction for improving maternal child health (MCH) in Korea. We reviewed two MCH services which are directly related to premature infants: 1) a registry and financial support program for families with a premature infant, and 2) financial support to build neonatal intensive care units in rural public hospitals. Suggestions are made for the development of a national vital signs record system to identify high risk infants and to monitor the trends in infant mortality due to prematurity. Prevention efforts and preconception care for childbearing women is also an important strategy to reduce the rate of preterm births. Finally, we need consider long-term follow-up plans for premature infants for a successful transit to the special education system. Developing MCH policy related to premature infants that decreases the occurrence of premature may decrease infant mortality, and also improve maternal and child health services.

City Train Technology that is large and complex system and consists of mechanical, electronic, electric, materials, computer, communication, civil/track etc. is very important area of railway industry, national fundamental industry. The standardization of city train system as a public transportation method and foundation of national economy is very important in order to do effective operation and to get fundamental technology, and the information system of the standards is required to operate the city train system effectively. By building data base of city train system design knowledge using computer-aided system engineering tool-Cradle, the system development issues and the design solutions are used by all engaged persons, and are managed by modeling and documentation. And this system will support architecture design consistently and effectively by applying this system to formalize early development process, to system requirements and configuration management, to system interface analysis and management and to system behavior analysis etc.. This study is for construction of data base of system design knowledge through making data base of many kinds of standards using CASE tool based on System Engineering Process, and introduces a model to support concurrent engineering for all engineers involved in system development allowing access to standard DB through Web from anywhere and at anytime.

Recently inside nano liposome particles or nano-emulsions which contain tough-melting physiology activity materials or the coefficient of low organism utilization promote the coefficient of organism utilization, so this part has been studied a lot because they can absorb selectly cosmetics, specially physiology activity materials, into the skin. Also, in particle size, cells interstitial lipid interval are 30~50nm, so nano-emulsions that the size is similar to 30~50 nm are made to study for absorbing quickly into the skin. And transparent skin which contains oils in common skin lotion dosage form has become the center of public interest. The used nano-emulsions in this study were unsaturated lecithin/co-surfactant! ethanol/ oil / water. And polysorbate 20/ polysorbate 80/ Dicetyl phosphate/hydrogenated .caster oil/ isoceteth-20/SLS were used in co-surfactant. The used oils were cyclomethicone and caprylic/capric triglyceride. The manufacturing process was that microfluidizer was fixed in 1000bar and transit times were changed from 1 to 10 times. From transparency and particle size, the transparency sequence was SLS> polysorbate 20= polysorbate 80> isoceteth-20> dicetyl phosphate >hydrogenated caster oil and the particle size was small. Specially cyclomethicone nano-emulsions, when we made unsaturated lecithin /SLS /ethanol/water/cyclomethicone, cyclomethicone 5％ was good for transparency. And 20％ of this was used for making transparent skin toner in common skin dosage form.

PURPOSES : This study presents a specific methodology for air dispersion analysis of urban areas methodology in accordance with urban planning and transport policy. METHODS : This study performed three alternatives including development density and public transit applying integrated urban model for the Delft city on Netherlands. Based on this result, the two types of air pollutant emissions($PM_{10}$, NOx) were calculated and analyzed the emission dispersion on that City. RESULTS : As a result, the quality of air near the City is better than that of current conditions showed that approximately from 2.1 to 7.9% according to alternatives. CONCLUSIONS : Air quality assessment in urban areas can be reasonably performed by applying a methodology when urban development and transport policy are considered.

This paper examines government-supported university programs in South Korea over the last decade. To do this, we review the current status and issues of recent programs supported by the Ministry of Education. Thereafter, we draw some lessons and suggest policy implications for improving the effectiveness of government-supported university programs. The issues addressed include 1) low consensus amongst stakeholders in the higher education sector and top-down goal setting led by the government, 2) frequent reshuffling of the structures and contents of programs, 3) ineffectiveness due to redundancy of projects, 4) disparity between 'haves' and 'have-nots' in the higher education system, and 5) an inadequate evaluation system and assessment indicators. We suggest that government-supported programs should be realigned to stimulate the reform of higher education aimed at strengthening its publicness. The role of government needs to transit from 'leading' to 'supporting', while the universities should take initiatives in reforming the higher education system.

본 연구는 철도 네트워크에서의 통행배정 모형에 관한 것이다. 기존의 통행배정모형은 주로 도로 혹은 도시 대중교통 네트워크에 초점을 둔 연구로서, 최적전략 기반 통행배정 모형을 비롯한 대부분의 통행배정 모형 이 지역간 철도 네트워크에 대해서는 비현실적인 수요를 생성한다고 알려져 있다. 특히 KTX개통 이후, KTX가 포함된 환승경로를 이용하는 승객이 점차 증가하는 추세이며, 이러한 KTX가 포함된 환승 경로 및 스케줄이 지속적으로 개선되고 있다. 본 연구는 환승을 고려한 새로운 다항로짓 기반 통행배정 모형을 제시한다. 특히 본 연구에서 제시하는 모형은, 통행 시간, 경로의 최소 운행횟수, 환승 저항 등 다양한 변수가 포함된 효용함수가 주어져 있을 때, K개의 최대 효용을 갖는 경로를 탐색하는 알고리즘을 포함하고 있다.

우리나라는 남북간 거리가 약 1,200km, 동서간 거리가 약 840km인 반도국가이다. 이 국토의 철도교통 인프라로 고속열차 KTX와 장거리용 일반열차, 그리고 대도시 지하철이 있을 뿐이다. 전 국토의75%가 산악지역에 분포된 우리나라에 관광 및 지역간 교통 수송을 담당하는 산악열차가 아직 운행되지 않고 있다는 것은 아쉬운 점이다. 국토 균형 발전 정책과 철도 인프라 구축 우선 정책의 원칙을 고려하여, 우선 3호선 구파발 역에서 북한산을 경유하고 4호선 쌍문 역 구간을 운행하는 산악열차를 건설한다면 관광 측면은 물론 서울의 서북지역과 동북지역을 관통하는 지선 역할 측면에서 모범이 될 수 있다고 본다. 설계, 건설, 운영의 친환 경성도 확보될 수 있음은 물론이다.

GTX(Great Train Express), the wide area express train of a big city center of metropolitan area, is the best new transportation method able to realize 'Low Carbon Green Growth' for solving traffic congestion of the metropolitan area with the connection the metropolitan area into 40-minute life zone by speeding up the standardized velocity, making the route straight and reducing the compensation of land using the space of 40~50m below the ground. In the transportation sector all over the world, if it turned into the public transportation system focusing on the train at a point of time that low carbon green revolution takes the initiative, national competitiveness would be enhanced by reducing the emission of carbon from cars by 1/6. Accordingly, this study is to look into the efficient operation in accordance with GTX construction superintended by currently Gyeonggi province and to consider the optimum operation plan of GTX that are proper for the actual circumstances of the country by comparatively analyzing overseas cases that took their positions as new transportation by curtailment of transit time through highspeed such as London area, Paris area, and Tokyo area etc that are similar to Korean metropolitan area.
