This paper is about the derivations of local volatilities for European quanto call option prices according to various types of payoffs. We derive the explicit formulas of local volatilities with constant foreign and domestic interest rates by adapting the method of Derman-Kani.

We compute the Hausdorff and packing dimensions of the cylindrical lower or upper local dimension set for a self-similar measure having different minimum and maximum of the local dimension on a self-similar set satisfying the open set condition.

We investigate a uniform local asymptotic normality for likelihood ratio processes based on an independent and identically distributed local asymptotic problem. Our tool is an empirical process theory.

We prove local existence and global uniqueness in one dimensional nonlinear hyperbolic inverse problems. The basic key for showing the local existence of inverse solution is the principle of contracted mapping. As an application, we consider a hyperbolic inverse problem with damping term.

This study has focused 302 environmental ordinances enacted from 1974 to 2008 by 16 upper-local governments (7 deignated cities and 9 provinces) and the relationships between them and the development of the Korean local autonomy system. The ordinances have been categorized into three types, the voluntary ones without any obligatory stipulations in laws, the optional ones based on laws, and the law based obligatory ones, which have been examined the enactment years and the contents of them. The local ordinances have been enacted in four periods with a few characteristics, which are "the pre-local-autonomy period (1974-1991)", "the introductory-local-autonomy period (1991-1995)", "the local-autonomy-developing period (1995-1999)", and "the mature-local-autonomy period (after 2000)", along the local autonomy development. 57 ordinances were enacted in the first period, 20 enacted in the second period, 46 enacted in the third period and 179 ordinances in the fourth period. The obligatory ordinances were the most in the first period and in the second period, while the voluntary ordinances were enacted most in the third period. 7 designated cities have pretty more ordinances, 160 in all, than 9 provinces, 142. The tendency to enact earlier in the metropolitan area, SeoulCity, IncheonCity and Gyeonggi province, than the others can be seen. It can be said that the establishment of the local autonomy in Korea had accelerated the development of the local environmental management.

This study was conducted to explain the capacity building policy of local public officials. Especially, it is to derive the policy task that can increase the efficiency within the limit of limited resources. The results of the study are as follows. First, local government officials' job management was the most important policy task in the largest framework to strengthen the capacity of local public officials. Next, the evaluation was in the order of recruitment management of local public officials and personnel management of local public officials. Second, the results of the evaluation of detailed policies. Among the local government officials 'job management, the introduction of the local government officials' rest period was evaluated as the most important. Regarding recruitment management of local public officials, reform of the public official exam courses was evaluated as the most important. In the personnel management of the local public officials, the job training of the elected officials was the most important. The results of this study will help to explain the policy development for strengthening the capacity of local public officials in realistic aspect. In order to strengthen the capacity of local public servants in future, it is necessary to analyze the measurement variables more.

This study investigated the local humanities ecosystem and the application of local humanities. A plan(measures) was suggested to vitalize the humanities ecosystem for local residents through this stduy. First, We looked at the support measures for local humanities. Second, we tried to find a measure to utilize research manpower for the development of local humanities. Third, We study ways to train researchers for the development of the local humanities ecosystem. Fourth, In this study, we analyzed the contents of the job creation plan for the development of local humanities.This analysis aims to establish a support plan for vitalizing research on the regional humanities ecosystem that reflects the local culture and regional specificity.

In Korea, various community investment renewable project models are being implemented to increase community acceptance of renewable energy. An important factor for enhancing local acceptance is that renewable energy projects have a positive effect on revitalizing the local economy such as income increase or job creation for residents and local companies. To maximize the local economic effect of large-scale community investment renewable energy projects, this study developed an evaluation index for local economy activation, whose indicators are the local return on investment, local companies' participation, local job creation, regional cooperation, transparency, and governance. Analysis of existing evaluation indicators and current renewable projects, financial analysis, and expert interviews were used in this research. The pilot evaluation determined that, the local economic effect was high in the following order: a fund investment wind project (Gangwon), benefit-sharing wind project (Jeju), and general wind project. In particular, residents' investment amount, the number of participating residents, and the amount and transparency of the regional cooperation fund were key factors to expand the effect of local economy activation. This evaluation index could be used in public bidding for renewable energy projects such as offshore wind zoning areas of local government.

This paper considers the use of local $\phi$-divergence measures between posterior distributions under classes of perturbations in order to investigate the inherent robustness of certain classes. The smaller value of the limiting local $\phi$-divergence implies more robustness for the prior or the likelihood. We consider the cases when the likelihood comes form the class of weighted distribution. Two kinds of perturbations are considered for the local sensitivity analysis. In addition, some numerical examples are considered which provide measures of robustness.

Let R be a commutative Noetherian ring, I an ideal of R, M and N two R-modules. We characterize the least integer i such that $H^i_I(M,N)$ is not weakly Artinian by using the notion of weakly filter regular sequences. Also, a local-global principle for minimax generalized local cohomology modules is shown and the result generalizes the corresponding result for local cohomology modules.
