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.

본 연구는 지역사회 애착도가 지역사회 축제 참여에 미치는 영향을 규명하고자 하였다. 천안지역주민을 연구대상으로 실증분석을 위해 320부를 설문조사하였고 SPSS WIN 12.0과 AMOS 4.0을 이용하여 구조 방정식모형으로 분석하였다. 연구의 결과 첫째, 정체성은 축제참여 관심도, 축제참여 정도 그리고 축제참여의도에 정의 영향을 미치는 것으로 나타났다. 둘째, 의존성은 축제참여 관심도와 축제참여 의도에 정의 영향을 미치는 것으로 나타났다. 그러나 축제참여 정도에는 유의한 영향을 발견하지 못하였다. 셋째, 사회적 친분은 모든 요인에 유의한 영향을 미치지 않는 것으로 나타났다.

본 연구는 주민센터 공무원들과 지역주민들의 보건사업에 대한 관심차이를 조사하여 향후 주민센터 공무원과 지역주민의 보건사업에 대한 관심도를 제고하기 위한 기초자료를 제공하고자 한다. 이를 위해서 주민센터 공무원 집단 46명과 지역주민 107명을 대상으로 하여 세부 보건사업에 대한 관심도를 조사하였고, 자료 분석은 카이검정(Chi-Square)과 독립표본 t-검정을 실시하였다. 분석결과를 종합하면, 주민센터 공무원 담당자들이 지역주민에 비해 보건사업에 대한 관심도는 낮은 것으로 나타났다. 보건사업 관심도 평균 차이에서도 지역주민이 주민센터 공무원 보다 유의미하게 높게 나타났다. 앞으로 주민센터가 보다 보건과 복지의 통합적인 역할을 담당하기 위해서는 공무원들의 역할을 확대시켜 나아가야 한다. 이를 위해서는 주민센터 공무원 및 지역주민들의 보건사업 등에 관한 관심도를 높여 통합적이고 유기적인 서비스가 이루어져야 하고, 지역주민들의 보건사업에 대한 능동적인 참여가 이루어져야 한다. 이는 주민센터 공무원과 지역주민의 보건사업에 대한 관심도를 높이기 위해서 다양한 모색이 필요하다는 것을 시사한다.

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.

본 연구는 지방 독자에 대한 체계적인 접근을 위해 지방 독자를 열독 유형에 따라 세 집단(중앙지 독자, 지방지 독자, 병독자)으로 나누고 각 집단의 속성 구분을 시도하였다. 따라서 지방 독자의 중앙지 지방지 열독 유형을 파악하고 유형별 인구사회학적 속성을 분석한 다음 지방 독자가 관심을 갖는 컨텐츠 및 광고에 대해 알아보았다. 또한 이를 바탕으로 중앙지 독자, 지방지 독자, 병독자 등 세 집단을 구분짓는 변인을 발견하기 위해 판별분석을 시도하였다. 중앙지 독자와 지방지 독자를 구분짓는 변인 중 영향력이 큰 것은 거주지역과 거주기간이었다. 병독자와 지방지 독자를 구분짓는 변인으로 교육수준, 서울 뉴스에 대한 관심도, 농축수산업 종사자 여부 등이 발견되었다. 일반적으로 지방 독자들은 서울 뉴스에 가장 높은 관심도를 보이고 광역시도 뉴스에는 낮은 관심도를 보였지만, 판별분석 결과 지방지 독자들은 광역시도 뉴스에 대한 관심도가 높다는 점에서 중앙지 독자와 구분되며, 반면 서울 뉴스에 대한 관심도가 낮다는 점에서는 병독자와 구분되는 것으로 드러났다. 이러한 결과는 지방 독자에 대한 평면적인 이해에서 탈피하여 신문 열독 유형에 따른 보다 입체적인 접근을 시도하는 데 기여할 것이다.

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.

The local behaviour of the surface formed by the perturbed maximum likelihood estimator of the squared Mahalanobis distance is investigated. The study of the local behaviour allows a simultaneous perturbation on the samples of interest and it is effective in identifying influential observations.
