As the population of persons and automobiles rapidly grows, parking problems also grow in large cities of Korea. The purpose of this paper is to first grasp the status of parking facilities and characteristics in large cities of Korea; and introduce new directions of CBD parking policies in north America cities: and finally recommend the adequate parking management strategies and tactics for improving parking problems in Korea. For this purpose, field survey for parking inventories, patrol survey for parking usage as observed demand and drive interview survey for parking behavior were conducted. Compared with the parking characteristics and polices of foreign cities, many differences of characteristics were found, and existing parking management policies, which should be improved, were identified. Five categories of parking management strategies were set on; a) Reasonable control of CBD parking demand, b) securing of the public parking facilities c) Promotion of privately operated parking facilities d) expansion of financial resources for parking facilities construction and e) Improvement of existing parking management system. And actural seventeen tactics to attain the above strategies were recommended.

We are faced with water pollutions on a population explosion. Considering the importance, we research European rivers based on OECD reports. Observations in the reports have defects that make evaluation of environmental situations be difficult. By using interpolations in the compensation quantitative structure-activity relation ships (CQSAR), we complement the defects in the water quality of rivers through big cities. Thus, we get complete data set for dissolved oxygen, biochemical oxygen demand, and total phosphorus. Using the data set, we examine re-naturalization of the Rhein and the Donau in Germany. We investigate the effect of dams between Slovakia and Hungary, by using reconstructions of neural networks in CQSAR. The reconstructions have functions to extract a principal relation. On the investigation, we examine assertions of conservation groups. As the result, we confirm the re-naturalization is effective, and find a negative effect of the dam construction on changes of dissolved oxygens in the Hungary Donau. We investigate the Seine and the Thames, too.

The purpose of this study is to review the trend in international marriage of Koreans based on Census data from 2001 to 2007 and to analyse socio-demographic characteristics of the married couples. This study remarks that as the primary causes underlying the recent increase in international marriages of Koreans, the change of worldwide condition such as globalization and localization, the condition of countries to leave immigrants, the change of sex/age ratio in population, and the change of value systems are addressed. Census data from the marriage and divorce registration for the period 2001-2007 are analysed. This study covers analysis of foreign partners' nationalities, remarriage, age gap between partners, education levels, male partners' occupation, region of residence and divorce in international marriage of Koreans.

In recent years, the change of urban function and the decrease in birth rate have given rise to merge, abolition and relocation of the existing building in cities. This study explores the possibilities for various land utilizations of relocated urban sites. In doing so, it compares the development methods and the utilization pattern between home and abroad. It analyses the land use categories and the development methodologies of 4 relocated urban sites happened in Seoul and 4 foreign sites. In addition, it analyzes the land utilization after relocation, development principals, area, building usage and changes in land use regulation. Finally, it proposes the directions for developing relocated site and each of roles among the parties concerned. This study concludes that it is available to exploit the relocated urban sites by the variety of development methodologies, especially in a metropolis like Seoul.

The purpose of this study is to explore the research and development(R&D) programs for effectively response of population aging. We analyzed of aging-related R&D support status by National Science and Technology Information Services(NTIS) and reviewed of foreign aging-related R&D programs. It was found that the overall lack of support systems, the R&D support status for Korea's aging society is very low performance and the difference appears in the annual support status, etc. It is very important to enhance the effectiveness of R&D programs in order to effectively prepare for aging society. I suggested support measures of the R&D for aging society by survey research. The result of this study will help in planning of the R&D for aging society and contribute to increasing of welfare for the aged.

With the increase in population, the area of human activities has expanded, resulting in the dramatic increase in the need for transportation system. Various infrastructures necessary for efficient logistics, however, have not been supplied enough and the logistics efficiency in Korea is in a bad situation now. As a result of the situation, the demand for the railroad transportation system that can provide large volume transportation has increased dramatically. An electric railway system is composed of high-tech subsystems, among which main electric equipment such as motors and converter are critical components determining the performance of electric vehicle. Among the on-board equipments, traction equipment is important part that has influence on safety and performances of vehicles. We is studied for high-speed train of foreign countries. From this research, we knows that axle weight of HEMU-400x is reasonable within 13ton.

In recent years, due to the continuous concentration of population and sharp increment of commuters around Seoul metropolitan area, traffic jam has become one of severe problems along with housing in this area. In oder to solve the problem like the one mentioned above, several countries such as Japan, France and so on gradually operate double deck trains as efficient, reliable and comfortable mass transportation systems. However, the double deck train has weak points such as big cross sectional area and high mass center that cause unsafe vehicle running performances and interface problems between the vehicles and infrastructures. Therefore, prior to operate double deck trains on the existing lines, careful investigations should be performed. For these reasons, we have investigated foreign double deck trains and studied the technologies for a double deck train as an alternative way to carry heavy transportation efficiently and comfortably.

At present, agriculture in Korea is experiencing difficulties, such as a stagnation in farm income, an increase in imported agricultural products, a decrease in arable land, a decrease in the self-sufficiency rate of grain, a decrease in rural population, and aging. To solve these problems and vitalize the rural economy, our government is promoting its 6th industrialization policy, which links agriculture with primary industry, secondary, industry and tertiary industry, and as well as smart agriculture based on information and communication technology. Smart agriculture is an agriculture form used to improve the quality of life in rural areas through making greater efficiency and intelligence by applying ICT convergence technology to the whole entire process of agricultural production, distribution, and consumption in the areas of outdoor agriculture, facility horticulture, and livestock. Therefore, in this paper, we analyze the policy, technology, and standardization trends of domestic and foreign smart agriculture, and suggest ways to apply them to domestic smart agriculture during the in the introduction stage.

The main question addressed in this research was whether an adaptation of a standard exercise Physiology Procedure would be sensitive enough to record excess oxygen uptake associated with speech activity. Oxygen consumption was recorded for a single subject during 7-minute rest periods and an automatic speech task, also 7-minutes long and performed at three different vocal efforts. The data show measurable and systematic speech-induced modifications of breathing and oxygen uptake patterns. The subject was found to use less power for normal than for soft and loud speech. This result is similar to findings reported by experimental biologists on the energetics of locomotion. However, more comprehensive feasibility studies need to be undertaken on a larger population before solid and detailed conclusions about speech energy costs are possible. However, it appears clear that, for experimental tasks like the present one, i.e., variations in vocal effort, standard exercise physiology methods may indeed offer a viable approach to recording excess oxygen uptake associated with speech movements.
