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.

In our study, we present a new LOGIT-based traffic assignment model applicable to intercity railway network. Most traffic assignment models have been developed for public transit assignment in urban area, so that they are known to produce unrealistic results in intercity railway demand analysis. Especially, since the introduction of KTX, more passengers are using a route including KTX service and the schedule becomes more compatible with transfer. Our study presents a new LOGIT-based traffic assignment model considering passenger transfer. To do so, we suggest a new route search algorithm to find K paths with non increasing order in the utility value.

Korea, a peninsular country with distances of approximate 840 kms south-north and 1,200 kms east-west, currently has only three types of rail transport mode in operation; high-speed KTX, regional railway and urban rapid rail transit. It is very unfortunate that there exists no mountain train system across the country yet, which could be able to contribute both to the promotion of tourism and to a higher affordability of public transport means in the city. This type of rail mode system is more desiring when taking account the fact that 75% of the land topographically belongs to mountainous area. With this background in mind, among others, it is suggested that a mountain train system be laid over the scenic Bukhan Mountain in Seoul linking Gupabal station in line 3 and Ssangmun station line 4. This project would surely require an advancing review on its feasibility and approving result.

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.
