  • Territorial sea baseline is a borderline, with the effectuation of the United Nations Convention on the Law of the Sea of 1982, for the related sea zone negotiations with neighboring countries. Its position must be determined to international standard like WGS84 coordinate system. In this study, GPS survey for territorial sea points was performed to determine territorial baseline around five islands in the yellow sea, and the results of them were compared with previous coordinates. Territorial sea point, outermost spot of a nation's realm, tend to be placed in end up low-tide elevations or precipice. Therefore traditional surveying methods are hard to take accurate observations, so that GPS survey is most effective. Through the study, the scientific and reasonable methods for GPS surveying procedure is presented. The results of coordinate comparison show that there are wide difference between the old and new coordinates, and it is necessary for the whole area of islands to calculate displacements by GPS surveying.

  • The road safety depend on many road factors like vertical alignment, horizontal alignment and road cross section angle. These data are hardly to get with drawings, and the real data are differ from drawings because of road pavement overlay, etc. To get these data, so many time and cost are needed, moreover it is dangerous work in heavy traffic road. In this study we obtained the road safety data with RoSSAV(Road Safety Survey & Analysis Vehicle) of Korea Institute of Construction Technology in accordance with traffic flow, and make analysis of road safety with the vertical alignment, horizontal alignment and road cross section angle data. We derived the safety improvement method in Young-dong accident prone spot and described detail method in this paper.

  • The purpose of this study is to investigate the factors that affect the discrimination of low-income children among children in the community children's centers. The subjects of the survey were 6th grade elementary school students who were the third respondents of the second Child Panel Survey of the community children's center, among them, 355 children whose family economy level corresponds to basic living allowance, next level, and blind spot. SPSS Statistics 25.0 was used to analyze exploratory factors, reliability analysis, frequency analysis, descriptive statistics, correlation analysis, and multiple regression analysis. The results of this study showed that single parent family, parent social capital, parental abuse, and happiness had a significant effect on the discrimination damage of low-income children in community children's centers. The more one parent's family, the less the parent's role as a counterpart to the discussion, and the more the parental abuse, the higher the child's discrimination damage. In general, parents-related factors were affecting the discrimination damage of low-income children. Community children's centers and related institutions should focus on developing and implementing programs that can improve the quality of family relations of children.

  • The Korean economic crisis hit badly the local construction industry, especially during the year of the 1998 when the country took the IMF bailout proframme. Under the poor business environment, such as reduction of construction investment, financial difficulty from high interest rate, and increasing bankruptcies, restructuring measures were repuired for survival of the industry. It is obvious the restructuring process is essential for the future business success. regardless of the financial crisis. With this background, this research aims the contribute to improved construction management structure and strengthened international competitiveness of the industry through the cost reduction and productivity enhancement, by analysising and proposing and optimal level of the manpower structure of construction management organization With the subject of 24 construction fields of apartment houses in the capital region as of January 1, 1999, constructed by OO company having leaded the construction industry of the country so far now, the researcher performed the on the spot survey regarding the organization/manpower structure and construction contract amount.

  • Traditional methods for the extraction of the environmental factors of waters in which environmental change is severer than in the land can not examine closely the changed phenomena because of the lack of equipments, manpower, time and cost, etc. Therefore, new practical and efficient methods are required. The research for the method to manage environment of the waters with remote sensing technology was needed. This study examined the interrelations between the data by an on-the-spot survey and Landsat TM data and presented the model for extracting factors of water quality with regression analysis and experimental formula.

  • The purpose of this study is to develop an educational model based on the capacity analysis of college students. In order to measure the learning ability of female science and engineering students, we used various tools to derive core competencies. The competency element of human resources implementation, the element of learning achievement area in the undergraduate education actual condition survey, and the analysis of the learning achievement elements of the engineering certification program were analyzed and the development of teaching method was searched to find ways to increase the competence of female students. In addition, we developed a model that can apply the development of pedagogy in the curriculum to the liberal arts, majors, and comparative courses, and presented the internship in field experience area, the improvement of on the spot learning, and teaching method and guidance to enhance the female students' competence. Also, as a case study of the proposed teaching method, new curriculum of 'Understanding of Big Data' which is the basis of the fourth industrial revolution technology in the second semester of 2016 was developed and applied to the education model. The results of this study are very positive, and we can expect the effectiveness of the new education model to enhance the learning ability and capacity of female students.

  • This research aimed at measuring Park and Green Satisfaction (PGS) using subjective indicators of 'surface, line and spot' green evaluated by citizens. Also frequency of visits to park and green measured using objective indicators (number of visits) to find the relationship with PGS. A conceptual model of PGS was developed to relate evaluation to satisfaction and finally to utilization of open spaces. A sample of 500 questionnaire survey was employed for Uijeongbu City in Korea. A Structual Equation Modeling (AMOS) techniques was used to test the hypothesized relationship among factors (construct). As a result, first, PGS was explained by three latent factors of 'urban park' (${\gamma}=0.54$), 'linear facilities' (${\gamma}=0.25$), and 'surface green' (${\gamma}=0.15$) respectively. These three exogenous construct was found very useful classification system for open spaces of cities. Second, PGS (${\gamma}=0.34$) was found as a mediating variable to utilization of open spaces and also PGS was closely related to citizens Environmental Quality Satisfaction (EQS), such concept as, 'livability' and 'aesthetic quality'. The more satisfied with park and green the more people use the space. The PGS was an important QOL indicator together with the subjective indicator of 'livability'. Third, jogging and walking trails and bike ways along the river corridor was the most important green facilities contribute to the PGS and EQS. The near the distance (within 500m) the more number of visit to river corridor (green way). The river corridor promote accessibility to nature and other parks.

  • This study is to explore the housing problems and environment conditions perceived by residents in traditional houses in Suzhou, China. The empirical data is based on a questionnaire survey, which were from 100 residents in traditional area in Gusu area of Suzhou. In order to understand the traditional houses, on-the-spot investigation and literature review methods are adapted in this study. The main findings are as follows. Firstly, most of residents are middle-aged or older people, and their income is not high. Secondly, there are almost no cases of organizing independent workroom and storage room in their housing. Moreover, the main problems are mildew, theft, rats and cockroaches, etc. Finally, the satisfaction with the internal housing environment was appeared reasonable, but the external environment is unsatisfactory. Therefore, the external environment should be more considered in the Chinese traditional housing policy.
