One aspect of the globalization of the financial market after the 1980s is represented by the concurrent monetarization of the national stock markets. As the IR activity is regarded as a new financial productivity measure, the IR activity in the stock market is being emphasized domestically and internationally. This study analyzes domestic IR activities and compares them with foreign IR activities. Specifically the "road show", a typical IR activity, which is known to resolve the information asymmetry between the firm and the investors is analyzed to see the extent of the their value increase impact on the firm. The study employs domestic and international firms that publicly announced "road shows" after April 2004. Event studies are done to see the existence of abnormal return after the public announcement of road shows. Domestic firms were found to have positive IR impacts on the stock prices, but international firms were found to have negative IR impacts on the stock prices. Also it was found that international public announcement of the road show have stronger positive impact on the stock price than domestic public announcement. The investigation of the statistically significant difference of CAR before and after the fair public announcement enforcement rule showed that the positive CAR impact is strengthened after the adoption of the rule. The conclusion is that increase of the firm value after the road show implies that the information asymmetry is reduced by the active IR actions on the firm side. The policy implication is that we have to reassure the understanding of the role of the IR activities. Specifically Korean firms may have to encourage IR activities to share the information of the firms with the investors, which may result in the trustworthy relationship between the firms and investors.

The aim of this study is to compare open space planning between Australia and Korea by Local Governments Areas. Open space planning is carried out at the state and municipal level in Australia, but by metropolitan city government in Korea. This study is structured by reviewing the presemt phenomena of provision of open space in Sydney and Seoul, By measuring disparity in terms of open spaces by L. G. A. s an by comparing planning approaches between two cities, for example policy, government standards, government administration system in open space management. In this paper, the provision of parks in Sydney and Seoul are comparatively examined and geographically mapped, and multiple repression analysis is applied to measure the residuals from the line of equality. The results of this study show that, 1) During the last 1 dacade from '80 and '90. Sydney has increased the quantity of open spaces from ratio of 19.11ha/1000 to 22.33ha/1000 of parks, however Seoul decreased it by the ratio of 12.21$m^2$/person to 1012$m^2$ per person. 2) Sydney has more programs, such as Greenspace program, Metropolitan open space program etc. to increase and to distribute open spaces equally rather than Seoul which has less open spaces. 3) There exists patterned inequality in terms of open space provision in inner city and suburb between Sydney and Seoul. 4) Seoul requires more active polices to increase open spaces like Greenacre Program of New Jerrsey State, Double Open Space Pland of Tokyo or Green Space Program of Sydney.

The agricultural reservoir watershed plan suggests three specific indices or ways to measure the potential for maintaining reservoir quality in balance with existing or proposed uses: an index of the reservoir's vulnerability to accelerated eutrophication, an index of the degree of land use intensity in reservoir watersheds, and an index of present water quality. Three items that contribute to reservoir eutrophication are included in the vulnerability index: the ratio of reservoir volume to drainage-basin area, shoreline configuration, and mean depth. The watershed land-use intensity index is based on road proximity and upland watershed land-use intensity. Water quality can be given a COD level. All six indicators are considered separately and then rated as follow: low (1), medium (2), or high (3). Five out of 30survey sites were less than 8points, 17sites were less than 11points and 8sites were less than 14points. This study suggests that the sites in the first ranking were potential areas for preservation, sites in the second ranking were potential areas for environmental friendly planning and sites in the third ranking were potential areas for residential need oriented planning. The advantage of this study is the low cost of gathering data for the development of local policy for the planning, management and protection of reservoir basin.

The focus of this paper falls on assessing how well rule of crafting government R&D institution spin-off companies(GRSCs), legitimatized to boost up technology commercialization of government research institutions(GRIs) at Daedeok Innopolis in 2006, affect the better business performance of GRSCs, but also delivering alternatives of driving up their better business. First of all, this paper evaluate a management performance of GRSCs at the financial aspect by taking 5 different GRSCs cases among 16 to measure the overall performance of GRSCS's Technology commercialization. Second, this paper assess the effectiveness of GRSCs to bring the better performance of technology commercialization. Third, this paper suggest soft program-centered technology commercialization model, rather institution and ceremonial-oriented one, for GRIs. Overall, the outcomes of this paper will contribute to accommodate the rule of GRSCs attaining goals set in the initial policy domain.

The purpose of this research is to take a look at what are research autonomy's factors of the government-supported research institutes with a new angle and how these factors influence on organizational effectiveness at the same time. ultimately, this research will suggest what government should guarantee and support researcher of the government-supported research institutes. In the groundwork, this research divides the level of research autonomy individual and organizational level, and divides the type of research autonomy intrinsic and extrinsic autonomy and also organizational commitment, and measure job satisfaction for organizational effectiveness. consequently, intrinsic autonomy which is associated with 'selection of research project', 'freely and lively traffic in ideas', 'choice of research methodology', 'utilization of research's result' is much more important than extrinsic autonomy for researchers to improve organizational effectiveness.

The purpose of this study was to analyze the correlation between psychosocial factors and therapeutic flow in stroke patients and identify the factors influencing therapeutic flow. Total 168 stroke patients from 15 hospitals were measure for depression, stress, self-efficacy, rehabilitation motivation and therapeutic flow. Factors that affect the therapeutic flow correlation as s result of negatively correlated with depression(r=-.349, p<.001), stress(r=-.290, p<.001), self-efficacy(r=.528, p<.001), rehabilitation motivation(r=.186, p<.05) was found in the positively correlated. Finally the effect on therapeutic flow in stroke patients variables affecting self-efficacy(${\beta}=.443$, p<.001) and depression(${\beta}=-.155$, p<.05) were the order of analysis. These result demonstrate that the therapeutic flow of storke patients was a significant correlation on psychosocial factors, future study will continue to be needed.

This is a user experience study of factors that should be considered in designing home appliances experience service. Untact services are emerging, but the development of home appliances sector is in early stage. Based on the six factors of Stephen P. Anderson's Creating Pleasurable Interface Model, this study conducted surveys, 1:1 in-depth interviews, and participation observations to measure and analyze user experience. In this study, I compared 4060s and 2030s's user experience in that the untact services raise the digital alienation among middle-senior-aged. As a result, there were significant differences between the two, including the opposite satisfaction in terms of reliable, usable and pleasurable factors. I hope that this study will be of strategic help in designing future home appliance experience services.

This study aims to analyse the spatial characteristics and to draw the declining areas from the whole area of Chung-Cheong Province. For this purpose, the temporal and spatial conditions by the urban decline diagnosis indexes are utilized. Additionally, the spatial autocorrelation method was applied for extraction of those areas. The spatial autocorrelation method is one of the methods on exploring spatial characteristics and considering the spatial factors. We also adopted the concepts of economics and then discovered the characteristics of deprivation areas. In applying this method, the positively valued areas were classified as the complementary areas, and the negatively valued areas as the substitutional areas. The findings show the declining areas and the growing areas caused by the growth of periphery. This study supports the regeneration plan of Chung-Cheong Province in extracting depressed or activated areas and explaining the characteristics of those areas.

The purpose of this study is to analyze service quality factors that affect user satisfaction of Open Access Korea(OAK) services and to draw strategic assignments for activating open access activities in Korea through a user satisfaction survey. User satisfaction indexes were developed to measure all aspects of the OAK services. The quality index, satisfaction index, and performance index were identified in this survey. According to the survey findings, the levels of social quality and social satisfaction are relatively high, this shows the positive evaluation and expectation of researchers for OAK services. However, relatively low level is identified in the area of service process quality, and many opinions about OA contents shortage in Korea represent the importance of the national level contents development strategy. Sustainable policy support, publishing of open access journals, management of institutional repository, OA governance system, expansion of researchers' participation, construction of global collaboration system are suggested as major implications to promote open access activities in Korea.
