The region of Southeast Asia had already experienced rapid urbanization and cultural change before the East Asia region did. None the less, nowadays shophouses and rowhouses still form the major portion of streets in Chinese town in Southeast Asia countries. The purpose of this study is to examine the adaptation process of shophouse and rowhouse in the Southeast Asia region and the architectural characteristics between the middle of 18th and the early of 20th, which Chinese people of the region inherit and develop, for more thorough understanding of cultural adaptability and regionalism of Chinese architecture in Southeast Asia. The common fact found in the Southeast Asia region is that Chinese people in countries of this region gradually started to live densely as a group in a certain zone in city area since they got to play important roles in commerce, trade and service works related with cities, due to European countries' advance into Southeast Asia and their construction of colonial cities in the region. Chinese people in the region utilized residential rowhouse and special shophouse, which is a kind of shop adapted from rowhouses' sitting room or storage, for their commercial and industrial activities in urban areas, which had problems of limited space. They also realized high densities through vertical expansion of space in order to adjust to changing urban structure under execution of urban planning in cities of colonial area and rapid urbanization. Even though residence of Chinese in Southeast Asia was influenced by new political, social, economic and cultural rules of European colonies in Southeast Asia, it has continuously succeeded to the cultural tradition of China, their home country, in terms of planning principle which puts air well in the middle and hierarchial spacial construction method. Appearance of the open connected verandah, designed by Stamford Raffles, the founder of Singapore, can be regarded as one of the architectural characters. Hence, Chinese residence in cities of Southeast Asia can be understood as a new regional architectural culture in the context of European countries' urban planning and urbanization of colonial areas, Immigrants from southern China and their role, their adjustment to urban areas by utilizing mixed type houses of residence and business, cultural tradition of Chinese home country.

신용카드는 기능면에서 현금과 유사하게 사용되어지는 지불수단으로서 이를 이용하는 사용자가 지속적으로 증가해 왔다. 인터넷 및 전자상거래의 발전에 따라 신용카드는 지급결제 수단으로서의 역할이 더욱 증대되었다. 그러나 정보의 집중화 및 온라인화로 인하여 발생하는 위험 또한 급격히 증가함에 따라 신용카드의 부정사용 역시 증가하고 있다. 부정사용의 유형별로는 카드사와 금융당국의 대응방안 마련으로 도난 분실은 감소하고 위변조와 명의도용이 증가하고 있다. 최근 개인정보유출과 간편결제 시행에 따른 금융보안규제 완화로 카드 부정사용에 대한 소비자의 불안감이 커지고 있고 카드 부정사용의 증가는 사회적 비용을 초래할 뿐만 아니라 신용시스템에 대한 금융소비자의 신뢰를 떨어뜨리므로 이에 대한 대책이 필요하다. 따라서 본 논문에서는 카드 운영 체계의 보안문제점을 살펴보고 부정사용을 방지할 수 있는 방안으로 IC단말기로의 조속한 전환, 새로운 보안기술의 도입, 당국의 관리 감독 강화 등을 제시하고자 한다.

This study aims at examining the background and development process of Masan city after Koryo Dynasty, making a reconstructive map of Original Masan using the first registration maps made in 1912 and analyzing the urban structure of the Original Masan area. The origin of Masan city went back to Koryo dynasty. Around 1040 Koryo government placed an official shipping facility in Masan to transport the taxed grain to the capital city. After that Masan became an important port covering the southern part of KyungSang-Do. And the urbanization of the Original Masan began to bud after a shipping facility was again established by the Chosun Dynasty in 1760 and strengthened in the 19th century after the social standing system was broken and many peasants moved to cities as daily workers. In 1899 Masan was forced to be opened to foreign powers and they placed an international settlement distanced from the area(Original Masan). After this many Japanese advanced to the international settlement and further to the area. The advancement of Japanese brought a critical change in the urban structure of the area. Land was owned by Japanese and many modern sysytems were introduced such as modern buildings, new roads, railroad and modern factories. According to the reconstructive map of the area, 80.5% of land lots are less than $200m^2$ showing the size of each land lot is comparatively small. And Japanese occupied 31.5% of the land in the area. Their land was located on the stratigic points near the port and the center of commerce. The ratio of the road area to the whole land was around 14%, not so low for urban areas in that time. The reconstructive map reveals the exact coastline of the year 1912 erased now due to filling the sea and extending the land, Present Masan city has been developed having the Original Masan as its nucleus. The area has been always the center of urban activities for Masan city. Making an exact reconstructive map for the area and analyzing the urban structure of the area in 1912 is a very important work to understand Masan city wholy.

The purpose of this study is to research the change of Tibet's commercial district following Tibet's globalization(traditional clothing to modern clothing). Tibet's traditional culture is fastly changing for two major reasons: Chinese government's persistent assimilation policy on minority ethnic groups and globalization, a powerful trend worldwide. Therefore this investigation was conducted on the most preeminent feature of life, clothing culture, at capital city Lhasa where modernization is most prominent and fast in Tibet. For this, the first field investigation was conducted between February 5th and 15th, 2007. and the second investgation was between January 16th and 25th, 2008. As a result, the study on clothing globalization in Lhasa, Tibet, reaches the conclusion as follows: Based on such developments, commerce of Lhasa has been modernized, bringing about great change in composition and formation of its commercial district. Stores have been modernized and their service quality has improved. While the number of traditional clothes shops has decreased, various types of modern clothes shops have emerged. Modern clothes stores mostly consist of quality men's wear shops, casual clothing shops targeting those in their 20s, and sportswear shops reflecting global trend. This composition indicates that it is men and younger generation who first adopt new culture emerged through globalization. Tibet's modernization and social development have become an integral part of globalization and public sentiment. Therefore, its modernization will be driven by power and capability of the public, rather than by policy control of the central government.

The spatial separation of male's and female's area due to the law of 'Naeoei' is one of the trademark features of residence by the building principle of 'Confucianism' in the upper class house in the late of the Chosun Dynasty. Thanks to modernized agriculture and commerce, the residence of 'Sinheung-Yangban' developed. And they were influenced by the economic and living characteristics than traditional custom. So the residence of 'Sinheung-Yangban' is very important in terms of the course of modernizing of the korean traditional residence. Researcher figures out the influences of the law of 'Naeoei' in residence and the characteristics of male's and female's field in terms of daily life with investigating the residence of 'Sinheung-Yangban' as the upper class house in the late of the Chosun Dynasty. Through this, the goal of this study is to find the properties of male's and female's field of upper class houses in the late of the Chosun Dynasty. With this study, the followings are the characteristics of male's and female's spatial composition of upper class houses in Gyong-gi Province in the late of the Chosun Dynasty. First, the traditional law of 'Naeoei' plays a primary role as the principle of building of upper class houses in Gyong-gi Province in the late of the Chosun Dynasty. With a natural result, there is a clear spatial separation as the male's and female's social role. Second, 'An-Chae' and 'Sarang-Chae' as male's and female's living space are separated physically, but real living life tends to be syntagmatically made with 'An-Madang' as the center. Third, spatial integration of 'An-Madang' as the center results in the development of architectural connection factors of 'An-Chae' and 'BaKat-Chae' adjoining 'An-Madang', facing 'Toei-Gan', 'Maru', and 'door'. Forth, the boundary of male's and female's areas is relatively clear between dwellers and visitors, but on the other hand, the separation of male's and female's spaces between family members has little significance.

The structure of noble centered social status of the late Joseon Dynasty collapsed due to the commoner's higher status and increased level of consciousness caused by the growth of commerce and agriculture. In art, the a Korean and ethnical style dominated; however, with a diversity in the depiction of human figures in portraits, Buddhist paintings, genre paintings and folklore paintings. This study examines the diversity in human figures expressed in the paintings of the late Joseon Dynasty by expanding the common aesthetic fixed to the typical Joseon style of renowned painters. The conclusion of this study is as follows. The human figure is categorized into three different types of 'realistic', 'ideal', and 'distortion' based on the aesthetic category. First, the realistic type is defined literally by its realistic and detailed depiction of noble class portraits classified as extreme type and general type. The extreme type's formative element is hypersubtlety which includes a simultaneous aesthetic of aptness and ugliness. The general type shows subtlety with aesthetic of aptness. Second, the ideal type is defined by representing the standard form of time and criteria classified as beautified type, absolute type, and dignified type. Each shows a different character of gender of femininity, androgyny, and masculinity. Third, distortion types are defined by a characteristic expression of humans by transshaping the features in various methods categorized as grotesque, abjection, friendly, rustic, and caricature type. Each shows different formative elements of bizarre, patheticness, voluptuous, inartificial, and immaturity.

Smartphone applications like games, image processing, e-commerce and social networking are gaining exponential growth, with the ubiquity of cellular services. This demands increased computational power and storage from mobile devices with a sufficiently high bandwidth for mobile internet service. But mobile nodes are highly constrained in the processing and storage, along with the battery power, which further restrains their dependability. Adopting the unlimited storage and computing power offered by cloud servers, it is possible to overcome and turn these issues into a favorable opportunity for the growth of mobile cloud computing. As the mobile internet data traffic is predicted to grow at the rate of around 65 percent yearly, even advanced services like 3G and 4G for mobile communication will fail to accommodate such exponential growth of data. On the other hand, developers extend popular applications with high end graphics leading to smart phones, manufactured with multicore processors and graphics processing units making them unaffordable. Therefore, to address the need of resource constrained mobile nodes and bandwidth constrained cellular networks, the computations can be migrated to resourceful servers connected to cloud. The server now acts as a bridge that should enable the participating mobile nodes to offload their computations through Wi-Fi directly to the virtualized server. Our proposed model enables an on-demand service offloading with a decision support system that identifies the capabilities of the client's hardware and software resources in judging the requirements for offloading. Further, the node's location, context and security capabilities are estimated to facilitate adaptive migration.
