Most recent E-mail systems, that are serviced in Korea, are supporting Hangul in many fields of E-mail(For example, contents, subject, attachment, etc.). However, these systems do not support Hangul in the address field of E-mail. In 2003, IDNA built the international standard in order to support multi-lingual besides the alphabetic character, a number, and '-'. So, Hangul cab be used in the domain part where is the right of '@' mark among the compositional element of the E-mail address. But, the local-part, where is the left of '@' mark, doesn't still support multi-lingual. So Hangul cannot be used in the local-part. In order to support multi-lingual including Hangul in the local-part, this paper designs and implements the E-mail system according to the EAI standardization research that it is progressed in IETF.

We have investigated coarse wind sectors in Busan metropolitan area and simulated detailed wind field using local atmospheric circulation model, RAMS in preceding studies (Part I, Part II). In this study, we divided and analyzed local wind sector in Busan according to the preceding results. We found that Busan metropolitan area is divided into 2 or 3 local wind sector in each coarse wind sector. The 9 coarse wind sectors were classified into 20 local wind sectors in total. But three local wind sectors were finally excluded because of these sectors were located on the complex hill area and the sea. Local wind sectors, therefore, in Busan metropolitan area were defined as 17 regimes. We assessed the location of air qualify monitoring sites at Busan metropolitan area using the information of these wind sectors. Most of these were located at proper points, but 6 sites were placed at 3 local wind sectors as a couple and no site was set up at 3 other sectors. Hence the location of these sites was in need of rearrange.

In this paper, a hysteretic model of rectangular hollow section (RHS) columns that includes the deteriorating range caused by local buckling is proposed. The proposed model consists of the skeleton curve, the Bauschinger part that appears before reaching the maximum strength, the strength increasing part of the deteriorating range, and the unloading part. Of these, the skeleton curve, including the deterioration range caused by local buckling, which is considered to be equivalent to the load-deformation relationship under monotonic loading, is obtained through an analytical method. Bi-linear hysteretic models based on experimental results are applied to the Bauschinger part and the strength increasing part. The elastic stiffness is applied to the unloading part. The proposed model is verified by comparing with experimental results of RHS columns under monotonic and cyclic loading.

The performance of face recognition methods using subspace projection is directly related to the characteristics of their basis images, especially in the cases of local distortion or partial occlusion. In order for a subspace projection method to be robust to local distortion and partial occlusion, the basis images generated by the method should exhibit a part-based local representation. We propose an effective part-based local representation method named locally salient ICA (LS-ICA) method for face recognition that is robust to local distortion and partial occlusion. The LS-ICA method only employs locally salient information from important facial parts in order to maximize the benefit of applying the idea of 'recognition by parts.' It creates part-based local basis images by imposing additional localization constraint in the process of computing ICA architecture I basis images. We have contrasted the LS-ICA method with other part-based representations such as LNMF (Localized Non-negative Matrix Factorization)and LFA (Local Feature Analysis). Experimental results show that the LS-ICA method performs better than PCA, ICA architecture I, ICA architecture II, LFA, and LNMF methods, especially in the cases of partial occlusions and local distortion

The purpose of this study has two folds. For the local government it gives a guide to establish the housing information system, which provides various housing information in order to promote service to the public on Internet. It also gives a guide for the local government to collect the fundamental data from local housing market and provide them to the policy makers as well as the housing producers (landlords, builders and owner-occupiers). Contents of housing information system website for the local government consist of three main parts. The first part provides housing policy and local housing market information to the upper level local government as well as housing producers. The second part provides housing information for the people who are looking for houses to move the own. Final part provides the procedures of building construction and development plan for landlords to the public. In case of Pyongtaek-City, this study makes them by cluster analysis of houses and households moving pattern as the Internet contents. Housing markets of Pyongtaek-City divide 3 sectors by housing type, tenure type and housing supply ratio etc. And populations prefer to move intra sectors. According to this information, policy-makers should define local housing problems and find solutions and housing producers can supply the house just in sites and in time. In conclusion, local government should provide valuable housing information based on local housing market research to the public for the effective housing policy. As local housing market is formed by various factors it is needed for local government to research housing sub-markets due to apply these research results to the local government for the future.

This paper mainly studies two films created by Huo Jianqi, Nuan and Postman in the Mountains, and analyzes the aesthetic style of Huo Jianqi's local movies in three parts. The first part deals with the characteristics of Huo Jianqi's local movies and discusses the theme selection, theme performance, character creation and emotional expression of the film. The second part elaborates Huo Jianqi's film and television works from three aspects: picture language, voice language and color language, which further reflects Huo Jianqi's aesthetic style. The third part analyses the puzzlement in the development of local films and how to develop them. With its unique oriental aesthetics, unique perspectives, unique rural scenery and characteristics, Chinese local movies have become the most representative of the overall level and style of Chinese movies. Chinese local film is the reflection and care of Chinese local culture, showing strong regional local culture, regionality is its distinct feature. Since the reform and opening up, with the changes of the times and the renewal of film directors, local films have shown distinct characteristics of the times. Through the analysis of Huo Jianqi's aesthetic style of local movies, this paper hopes to provide some valuable reference and inspiration for the development of Chinese local movies.

Some industrial steel structures are composed by components linked by several welding joints to constitute an assembly. The main interest of assembly simulation is to evaluate the global distortion of welded structure. The general method, thermo-elasto-plastic analysis, leads to excessive model size and computation time. In this study, a simplified method called "Local and Global approach" was developed to break down this limit and to provide a accurate solution for distortion. Local and global approach is composed of 3 steps; 1) Local simulation of each welding joint on a dedicated mesh (usually very fine due to high thermal gradients), taking into account for the non linearity of the material properties and the moving heat source. 2) Transfer to the global model of the effects of the welding joints by projection of the plastic strain tensors. 3) Elastic simulation to determine final distortions in global model. The welding deformation test for mock-up structure was performed to verify this approach. The predicted welding distortion by this approach had a good agreement with experiment results.

We calculate moment magnitudes of earthquakes occurred in the southern part of the Korean Peninsula from January, 2001 to February, 2004 and compare them with local magnitudes published by KMA(Korea Meteorological Administration) and KIGAM(Korea Institute of Geoscience and Mineral Resources). From this study, we find that local magnitudes of KIGAM have higher correlation with moment magnitudes than local magnitudes of KMA have. We induce a proper conversion formula by analyzing relation between published local magnitudes and calculated moment magnitudes. The induced formula can be used to unify kinds of magnitudes in earthquake catalogues and unified earthquake catalogues can be applied as necessary factors for analyzing earthquake characteristics, seismic hazards or attenuation formulas in the southern part of the Korean Peninsula.

In conventional approaches such as a functinal approach or a parametric approach to online signature verification, which could not deal with the local shape of signature, much various important informations inherent in the local part of signature shape have been overlooked. In this paper, we try a structural approach in which a signature is represented as a structural form of handwriting primitives and the local parts along a signature handwriting can be selectively compared according to their discrimination power in the process of signature verification, As a result, the error rate is diminished in the case that the weights of subpattern units is applied into comparing process, which is the degree of discrimination power of local part. And also, the global variation and complexity of each signature extracted from the analysis of local shape is found useful in determining the decision threshold more precisely.
