This paper is about the local volatility for the price of a European quanto call option. We derive the explicit formula of the local volatility with constant foreign and domestic interest rates by adapting the methods of Dupire and Derman & Kani. Furthermore, we obtain the Dupire equation for the local volatility with stochastic interest rates.

This study was intended to provide basic data for increasing the interest in health projects for the public servants and local residents in the period ahead by examining the difference in the degree of interest in health projects among the public servants at resident centers and the residents. For that, 46 public servants at resident centers and 107 local residents were sampled, and their degree of interest in specific health projects was analyzed based on Chi-Square and independent sample t-test. Based on comprehensive consideration of the results of analysis, public servants at resident centers were found to have lower interest in health projects than local residents. The results of this study showed that the public servants at resident centers had lower interest in health projects than local residents. That arises from the consideration that specialization is important for implementation of special works. Thus, this study needs to focus on expanding the role of public servants to ensure that resident centers can take on integrated role related to public health. Therefore, the results of this study can provide basic data for expanding the role of public servants at resident centers. Moreover, the results of this study suggested that various ways need to be explored to increase the interest in health projects for local residents.

This study aims to analyze and compare environmental attitudes of interest groups, including visitors, local residents, Buddhist monks, and staff of the Korea National Park Service in Gayasan National Park. To achieve this purpose, five hypotheses were formulated and tested. While three hypotheses were statistically rejected, two were accepted. In every interest group, the environmental attitude level of women was higher than that of men. Local residents particularly showed statistically significant differences in accordance with occupation. The difference in environmental attitude between visitors and local residents was not statistically significant. Finally, the environmental attitude level between interest groups was divided into three groups. The staff of the Korea National Park Service showed the highest level of environmental attitude, followed by Buddhist monks, and a group of visitors and residents recorded the lowest. However, the average level of environmental attitude of every interest group scored above the mid-point of 3. Therefore, it can be concluded that there exists no difference between or conflicts among interest groups related to strengthening conservation and management policies regarding the protection of Gayasan National Park.

The influence of observations in the equicorrelation model is investigated using the local influence approach when all parameters or subsets of parameters are of interest. When a parameter of interest is scalar, an analytical form of the local influence measure can be found. We will derive a measure for identifying observations that have a large influence on the test of fitting the equicorrelation model. An example is given for illustration.

This paper is focused on the desirable improvement schemes of the local network of information and telecommunication network. In this study, we examined whether polices of information and telecommunication of government have been carried out a desirable programme to meet the public interest, found out several problems in the these policies. Such problems as follows : (1) a system of local information & telecommunication is developing by a Model of Top-Down. In the present management system, an interest of the public of local society about the local telecommunication network is a much lower level, (2) there is no general controlling roll of the local information & telecommunication, (3) there is no service controlling system of local telecommuni-cation, and (4) there is no organic coordinating system of inter-departments in the central government level. In order to resolve these problems, this study suggests a few desirable sxhemes for the local telecommunication : (1) an establishment of middle-long range planning for the integrated future network of info-telecommunication, (2) an organizing of telecommunication network being suitable for the local characteristics toward B-ISDN.

This study aims to analyze and compare the environmental attitude level and characteristics of interest groups, including visitors, local residents, and local public servants (Cheongsong-gun), in Juwangsan National Park. A statistical analysis of 418 questionnaires concluded that there was no statistically significant gender difference in the level of environmental attitude between the visitors, local residents, and local public servants. In the case of visitors, no significant difference was found in the level of environmental attitude according to age and occupation, but the level of environmental attitude of local residents showed a significant difference according to age and occupation. In general visitors, local residents, and local public servants all scored above the mid point on average, but no statistically significant difference in environmental attitude was observed between these groups. Therefore, it is concluded that mutual consensus can be derived from these interest groups to strengthen the protection of Juwangsan National Park.

This study explores the attributes of local readers based on a discriminant analysis. Local readers are divided into three groups national newspaper reader, local newspaper reader, and national & local newspaper reader. A nationwide telephone survey was conducted in june, 2004 and gathered 2,063 cases. News subject and advertising appeared to play less important role in distinguishing among the three group examined. The most powerful discriminating variables were residence area and period of residence area. Education, interest of capital city news, job were found to be moderately important variables on Function 1, which distinguished between local newspaper reader and national & local newspaper reader. Generally, local newspaper reader showed higher interest on capital area news and lower interest on metropolitan area news. However, the result of a discriminant analysis indicated local newspaper reader was distinguished from national newspaper reader in terms of higher interest of metropolitan area news. Simultaneously, local newspaper reader was distinguished from national & local newspaper in terms of lower interest of capital area news.

As recently too many local museums have been built in the whole country, most of them cannot attract enough spectators. In order to resolve this problem, it is needed for local museums to differentiate their spaces and programs related to their exhibition. Thus, the purpose of this study was to analyze the characteristics of spaces and programs of local museums from the perspective of spatial marketing to activate them, and contribute to development of local cultures. This study targeted historical public museums located in Seoul and Incheon. Through preceding research, an analysis frame was established based on the keywords related to spatial marketing, and then the characteristics of spaces and programs of local museums were analyzed based on the frame. The study results are as follows. 1) Access convenience refers to openness that public museums located in Seoul and Incheon can embrace accessible locations, points of interest, and convenient facilities easily recognized by pedestrians. 2) Symbolic formativeness is to express symbolic historical contents in the museum lobby or exhibition to show the identity of local museums. 3) Visibility is needed for direct guidance signs or spaces to let spectators know directions and locations. 4) Public concern is for spectators and local residents to participate in local museums to share and utilize their partial spaces. 5) Interactivity is to induce activation of local museums by utilizing experience exhibition contents and having spectators directly contact exhibits. 6) Interest is related to cultural festival programs of exhibition to arouse spectators' and local residents' curiosity. 7) Participation is to activate spaces and spectators by providing educational programs. 8) Usefulness is to induce spectators' interest in local museums by providing historical, social, and cultural information. These results are expected to be used as baseline data to suggest a new direction for activation of local museums from the perspective of spatial marketing.
