As local flash flood exceeding planned capacity occurs frequently, localized preparedness and response to flood inundation are increasingly important. Using XP-SWMM model and GIS techniques, this study analyzes inundation areas by local flash flood and develops rainfall standards for evacuation with the case of Sadang-Cheon area, a local stream and its nearby highly populated watershed in the southern part of metropolitan Seoul, Flood inundation areas overflowed from drainage systems are analyzed and mapped by amount of rainfall that is derived from reference levels of stream flow. Rainfall standards for evacuation are comprised of 'watch' (40mm/hr) in preparing for near-future inundation and 'evacuation' (65mm/hr) in responding to realized inundation. The methods suggested by this case study may be applied to other urban areas for sound flood prevention policy measures and thus risk minimization.

Nowadays, digital maps of 1:5,000 scale are used to plan and review far road alignment design. However, the updating and modifying period of digital maps is not so harmonious as topographical changes caused by rapid developments can be reflected in digital maps, the different areas between real surface and digital map can be found easily. This research is aimed to suggest that the use of high resolution satellite image is effective way to get latest topographical information for road alignment design about wide region. IKONOS satellite images were geometrically corrected, and the road alignment data previously designed by traditional procedure were overlapped on the satellite images. As a result, the satellite image maps clearly described wrong road alignment, and modification of road alignment could be accomplished adequately By these procedures, road alignment design was Improved in quality, and could be reasonable and economic design to prevent modification that would be happened in the next step of practical plan. For the geometric correction method of IKONOS images, Thin Plate Spline(TPS) transformation with large number of ground control points, as well as ortho rectification, was effective.

The purpose of this study is to find a reasonable solution that is compatible with the government's policy on calming the overheated housing market and the needs of prospective home buyers. For this purpose, this study analyzed the current state of the housing market and looked at the root cause of the people's desire to purchase housing. And this study suggested the need to introduce a super-long-term mortgage system that can help people choose whether to own or rent a house in accordance with individual preferences. The super-long-term mortgage system would be useful in that the majority of people who currently use mortgages prefer long-term loan products and that it could provide a chance to "get their own homes" by easing the monthly repayment burden for those who want to have homes. If the system is introduced in the future, it is necessary to make efforts for stable operation such as risk-hedge. In particular, the government should apply a limited application to end-users so that they can curb rising housing prices and contribute to stabilizing housing prices.

Under the "Act on Safety Control of Small Public Facilities (enacted in 2015)", each local government selects and conducts annual safety inspections for small public facilities. Among small public facilities, small bridges pose high risks and are heavily utilized by local residents, making them challenging to manage due to their large numbers and limited resources. Therefore, there is a need for a rational selection method that considers the management capacity of local governments, as well as the establishment of objective risk evaluation and maintenance planning for small hazardous facilities. In this study, we propose a selection method based on structural and functional classification of small bridges, considering the management capacity of local governments. Additionally, we present quantitative evaluation indicators for ten risk evaluation criteria, aiming to facilitate objective risk evaluation.

It is necessary to determine the current and future energy consumption by farm households for the rational specification of energy related policy in the Korean agricultural sector. Especially, It is important to identify the consumption by source of energy and by the crops. On the other hand, the world has tried to reduce the production of greenhouse gases and, in line with this, the Korean government established related legislations to contribute to this reduction (30% reduction in emissionsby 2020). The reduction target of the agricultural sector is specified as 5.2% of the national total. This study focuses on sampling design to determine the energy consumption and emission of greenhouse gases, and suggests several alternatives to improve the confidence level and to make a dent survey and estimation errors. The population for the energy consumption survey of the agricultural sector was derived from agricultural census data. In the case of commodities with high skewness, we cut the sample range to within the statistical significant range. The number of samples in each class is specified using the Neyman allocation method and 95% significance level. The estimation results are compared with the population to verify the statistical significance and several management methods of sampling errors are suggested.

The purpose of this study was to investigate the effect of decision-making activities in lesson on improving decision-making ability to meet bioethical issues in everyday situation. Worksheet for decision-making was consisted of six steps: Identification of problem, searching relevant information, generation of alternatives, identification of values for selection criteria, evaluation of alternatives, review of consequence. The results of this study showed that the scores of decision-making were increased by the activities of worksheets. The scores of identification of problem, generation of alternatives, and evaluation of alternatives were increased meaningfully. However, the scores of searching relevant information, identification of values for selection criteria, and review of consequence were not increased. It seems that all steps of decision-making ability could not improve by short-term learning. Low level performance was appeared on the step of searching relevant information and evaluation of alternatives. This result indicated that students could not apply the biological knowledge to decision-making in the face of bioethical issues. In conclusion, the learning experience of decision-making is essential to foster rational decision-making ability. The activity of decision-making should be included in science class and curriculum.

To construct buildings on limited land, the size of the building is important. The development process needs to be minimized because determining the size of a structurally safe building at the planning stage incurs considerable time and cost. This study proposes the Limit Slenderness Ratio Approximation Equation. This study examined an outrigger structure system among several systems proposed for controlling the lateral displacement in tall buildings. This study compared the Limit Slenderness Ratio Approximation Equation with the approximate equation by changing the variables of the building model, and examined the size of the building using the approximate Equation. As an analysis program, the MAIDAS architectural structural analysis program was used to conduct model-specific analysis. The appropriate scale of the building to minimize the error between the approximate value calculated by the Limit Slenderness Ratio Approximation Equation and the analysis result of the structural analysis program is as follows. As the number of outrigger installation increases, the error can be reduced; the ratio of the cores is reasonable, from 20% to 30%, and the arrangement of the column is suitable only for the outer column without an internal column.

The objective of this study is to find out how strategic human resource management(SHRM) of a facility security firm affects its organizational culture and behaviors of its members. This study was executed in June 2010 with facility security officers(FSO) in four private security firms by using a judgment sampling technique. A total of 343 FSOs were used in final analysis. Coefficient of reliability(Cronbach's coefficient alpha) of the survey was 0.691. The conclusion was as follows: First, SHRM of facility security firms exert its influence on organizational culture. That is, promotion of education/training, compensation, making avid followers, and career development may facilitate settlement of hierarchical, development-oriented, agreement -based and rationality-oriented culture. Second, SHRM of security firms would affect organizational citizenship behaviors(OCB), i.e., the promotion of education/training, compensation, making avid followers, and career development would tend to enhance consideration for others and altruistic, participatory, conscientious and gentlemanly behaviors. On the other hand, if proper compensation is not made, above-mentioned behaviors would decrease. Third, organizational culture of security firms tends to affect OCB. That is, when hierarchical, development-oriented, agreement-based and rationality-oriented culture is settled, consideration for others, altruistic, participatory, conscientious and gentlemanly behaviors tends to be enhanced.
