Although there have been systemic efforts of the government to solve the metropolitan transportation problems, demand and supply for transportation facilities are not matched, yet. Scenario analysis by integrating land use and transportation has been popular in developed countries as a tool of metropolitan transportation policy making, and it can be adaptable in the metropolitan areas. Purpose of the study is to develope a model to help policy decision making for metropolitan transportation by setting policy scenarios of land use and transportation integration.

This study examines the urban characteristics and decision of urban planning facilities analyzes independent variables having correlation with population size with metrical approach and then obtains the following results. First, In correlation analysis, major urban planning facilities invested in the analysis had high correlation to population size and in particular, school and sewerage showed very high correlations and consistent results between population size and variables related to urban planning facilities were drawn. Second, Urban planning facilities having higher discrimination affecting urban scale obtained by means of standardized discrimination function coefficient include sewerage, school, square and market in order. Third, Urban planning facility having the greatest influence on urban population among six urban planning facilities in multiple regression coefficients was sewerage, decision area of urban planning facilities in proportion to population size tended to wide and park and amusement park showed inverse proportion to decision area of urban planning facilities.

Bigger in the size, more diverse in the style, recently, the interest and necessity of effective safety consciousness during construction has been increased in the construction field. Through the literature reviews and questionnaire survey, this study proposes a realities of the effective safety consciousness in the construction field. The cause of safety supervision which influence safety prevention are diverse, among them, especially, the safety consciousness have great impact on the safety accident. According to, safety accidents can be protected through safety education and safety awareness of each employee. Ultimately, prevention and recognition against safety accident are changed depending on employed category of construction field, it is necessary to educate and confidence considering each employed category of construction work for safety supervision rather than to uniform education about safety consciousness.

The purpose of this research is to compare and to analyze eight different science textbooks Ⅱ (the last volume) that are presently in use at the high school. The items that were compared and analrzed are as follows: The construction of each textbook in quantity. The construction of experimentation contents. The construction of contents in textbooks. This study will provide the basic data that is needed to effectively accomplish aims of science education and to enable a guidance teacher to reconstruct the textbook properly to the real condition exiting in each school. The findings of the research are as follows: 1. There is little difference in quantity of materials. But there is difference in quantity of each unit. 2. The number of Gothic-type terms used in each textbook is not unified. The sort of Gothic-type terms used in each textbook is also varied. 3. Photographs and pictures are presented in black and white. They are used for only explaining. 4. Material and method used in experimentation are showed in many ways. But some units are given too much importance. 5. Contents are consisted variously according to authors under the basic frame of education curriculum.

Korea that included in the global capital division has accomplished the rapid economic development under the state-led since 1960s. Korean industrialization, based on light industry using women`s labor of the low wage, resulted in feminization of labor` with the beginning of economic development. Women`s labor market relates closely the process of industrialization under the project of economic growth. The purpose of this article is to examine the aspects of such changes in the employment structure of women`s labor. In particular, this article is focused on the changes of women`s labor market, based on the process of the industrial restructuring under the state-led and the global economy. As well, this paper perceives the composition of women`s labor, gendered hierarchies, patriarchy with the capitalism, and the stratified arrangement of women`s labor. In addition, this paper examines how the state has formulated the national labor policy, particularly the labor policy for women, to mobilize women labor for the project of the economic development, and how women workers have coped with difficulties.

The Land Suitability Assessment System is a newly introduced system that provides criteria for land use classification. It is introduced by the 「Act on Planning and Utilization of the National Territory」 in order to prevent unplanned development of the nation. It classifies land use types into 5 grades according to soil, location, and usability of the land. Most of the land assessed as first and second grade, tend to be planned as conservation area, while the land assessed as fourth and fifth planned as development area. This study aims at analyzing problems in applying the Land Suitability Assessment System into practice, seeking solutions for the expected problems, and suggesting the ways of improving assesment methods. This study examines possible problems in implementing the Land Suitability Assessment System and suggests proper solutions for successful performance of the system. It will be a useful reference for local municipalities to carry out the system. And suggests solutions for The Land Suitability Assessment System. The solutions for the Assessment System are suggested as follows: enhancing the status of Assessment System by revising its institutional system, strengthening linkage between Assessment System and planning system, establishing basic DB for the whole undeveloped land, improving assessment standards, facilitate training program for relevant government officers, etc.

This study was carried out to nvestigate- the effects of T-P concentrations in irrigation water on the growth, yield, and grain quality of rice. It acquire fundamental knowledges to set up irrigation water quality standards. The pot experiment was conducted with 5 treatments using irrigation water. It consisted of various total phosphorus concentrations (control, 1, 2, 5, 10 mg/L) and replicated four times with randomized block design. the results of this study showed that as t-P concentrations in irrigation water increases, plant height tended to increase. Dry weight of rice plant at t-P 10 mg/L was significantly higher than the control. However, t-P in irrigation water did not affect plant height, tiller number, plant; dry weight, yield, and quality of rice.

Objective: This study was performed to examine the relationship between community-based social support and psychosocial distress in workers. Methods: The study subjects were 596 workers recruited from 11 companies in Chungju city. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, job stress, work-based social support, community-based social support and level of psychosocial distress. Results: Hierarchical multiple regression analysis showed that workers with no chronic disease, exercise and sufficient sleep had a higher score of psychosocial distress than those with chronic disease, no exercise, and not enough sleep. Coworker's work-based social support and community-based social support were negatively associated with psychosocial distress. The R square value of total independent variables on psychosocial distress was 0.409, and that of community-based social support on psychosocial distress was 0.052. Conclusion: This study showed that community-based social support served as a protective factor against psychosocial distress in some workers. We recommend the establishment of a worksite stress reduction program in occupational level as well as community-based social support.
