The purpose of this study is to monitor genetically modified bean sprouts at traditional markets in Seoul and to investigate perception of traditional market merchants and high school students on genetically modified organisms (GMOs). We analyzed 30 bean sprouts that were selected at 11 traditional markets in Seoul using the method of polymerase chain reaction (PCR). Also, we compared perception of GMOs between merchants (n = 30) and students (n = 126). Knowledge test about GMOs was performed by students. The result of PCR, 16.7% of bean sprouts were confirmed as GM bean sprouts (n = 5). Students had significantly more exposure to information about GMOs than merchants (p < 0.05). Major information sources about GMOs were from mass media (television, newspaper and radio). About half of subjects were not aware that they eat GMOs and GMOs are sold to consumers. Only 17.3% of subjects had constant eating intent for GMOs after perceiving foods that he/she usually eats are GMOs. 51.3% of subjects had willingness to purchase GMOs if GMOs have same quality and lower cost than natural foods. 37.2% of subjects thought that GMOs would be harmful to humans. Students had more positive perception of GMOs' side effects than merchants (p < 0.01). There was no merchant who knew labeling of GMOs. 19.1% of students knew labeling of GMOs. Students' mean percentage of correct answers of six questions about GMOs was 45.2%. Therefore, providing adequate information about GMOs is needed for consumer's choice whether to purchase GMOs or not.

This study aims to analyze why South Korea has not used audit system but examination system and suggest policy reform for the system on the institutional context perspective. Institutional context is structured down to institutional legacy, motives, institutional constraints, actors' roles, and changed institution. I researched the literature on the subject and collected research materials from the Department of the Treasury and Audit Office website of New Zealand, Australia, United Kingdom, United States and South Korea. These were analyzed using for suggesting realistic and effective policy. Analysis showed that South Korea has used examination system due to institutional constraints and tried to increase reliability of financial statements by enlarging the meaning of examination, strengthening the ability of the Board of Audit and Inspection, enacting government examination standards, and making a comprehensive public announcement. Comparing with other countries where government audit systems are applied, there are still some vulnerable points in South Korea. In order to make up for the shortcomings, this study suggests several points: strengthening the ability of actors; systemizing internal control; expressing opinion; making a more comprehensive public announcement. It would be desirable for making further detailed studies of the points.

The channel improvement plan has contributed to the flood damage reduction studies and the plan has mainly performed by the levee construction which creates the cut river. The cut river has mainly used as the agricultural and housing purposes. Recently, however, it is considered as a natural wetland for the purposes of a flood control and preservation of nature. So, this study compares the economical benefits according to the purposes of the cut river utilizations such as an agricultural, levee construction for flood damage reduction, and wetland. The study area is the downstream part of Kok-Neung stream which is a main tributary of Han river. The agricultural and levee construction benefits are estimated based on the 'Agricultural and Forestry Statistical Year' (2000) and the 'Standard for River Design' (2001). The benefit or value for the wetland utilization of the cut river is estimated by the enquete using questionnaire. As a results, for the case of which the cut river is used as an agricultural land, the present net benefit is estimated as 195.81 million won, for the levee construction, as 20853.00 million won and for the wetland, as 24692.89 million won. Therefore, the wetland is the best choice for the cut river utilization.

This study aims to explore the characteristics of platform for social service delivery and the electronic voucher system as an instrument for the delivery. The paper discusses the concept and characteristics of platform and reviews the factors by which firms migrate to platform. Social service e-vouchers are an example of a government platform that pays e-vouchers to consumers and gives them the choice of services. Then it analyzes the case of platform establishment to deliver social services. The demand on welfare services has changed with demographic structure. The change in demand requires innovation in the social service delivery system and adoption of strategies to move to the platform. Factors that enabled the social service delivery platform to build both demand and supply sides include access to employment policies, industrial connection, workforce training, and requirements for social service eligibilities.

Today, people are becoming more conscious regarding environmental-friendliness, and the society as a whole is becoming more aware of it. With such phenomenon, the purpose of this research is to examine how comfort and pleasantness of indoor environment influences when selecting a place for multi-cultural complex. To demonstrate the stated hypothesis, I have preceded the experiment by selecting the C multi-cultural complex of closed-type structure and T multi-cultural complex of open-type structure. The next step I took, in order to validate the public's awareness of environmental-friendliness, was conducting a survey. I then deducted a conclusion through comparison and analysis of experiment measures with survey result. As a result of the research, the experiment measures of each air, light, heat condition of the T multi-cultural complex of open-type structure had a higher measurement for the comfort and pleasantness than the C multi-cultural complex of closed-type structure. Moreover, after validating the consciousness of the public through the survey, they had a tendency preferring T multi-cultural complex of open-type structure over C multi-cultural complex of closed-type structure in terms of comfort and pleasantness. To summarize, it is proper to conclude that the criteria - comfort and pleasantness of indoor environment - has influenced significantly when it comes to selecting a multi-cultural complex through both the experiment and the survey result.

This study presents a sensitivity analysis method for stochastic user equilibrium of multi-modal network flows. We consider a multi-modal network consisting of a road network for passenger cars physically separated from a transit network for public transport. We first establish a sensitivity analysis method with respect to arbitrary link parameters and perform a sensitivity analysis with respect to link capacity and transit line frequency as practical link parameters. Next, We establish a sensitivity analysis method and perform the sensitivity analysis with respect to modal split by passenger car and public transit. As with the elasticity of economics, these results can be important information for analyzing changes in travel behavior due to the changes in operation and policy of transportation facilities, as well as for analyzing the effects of these operational changes and policies. These results also can be utilized as a tool to constitute a multi-modal network design problem by using cooperative game theory.
