The study is for tracing the mutational process, considering the transformational process of wooden chamber tombs in Gyoungju region during 2~6 century. In addition, class features and the meaning of tombs were studied. First of all, the wooden chamber tombs were classified into 10 different styles(1A~IVC), based on the filling materials, the ways of structure, and the structure of burial chamber. There were only one or two tombs that belongs to the highest classes 'Ga'~'Da' in each period, which has the numeral features. Furthermore, the styles of the central wooden chamber tombs according to the period and the region have distinctive features and have changed so far. It shows that there are the rank among the tombs in the regions. In other words, regarding the ranks of the class 'Ga'~'Cha', there were strict rules and the limitations on the size of the tombs and the number and the quality of the burial relics. It means that the inner-outer size or the structure of the tombs and the number, quality of the burial goods depended on the buried person's birth or social classes, or achievements. Based on Shila social classes, the class 'Ga' tombs were for the highest classes when considered the size, burial relics, and the quality. The class 'Na' and 'Da' tombs were for the higher classes, 'Ma' for middle classes, 'Ba', 'Sa' for lower classes. In addition, 'Ah', 'Ja' tombs were for higher commoner, 'Cha' for lower commoner. Thus, class 'Ga'~'Sa' is the leading class of Shila.

As a method to increase the scalability and efficiency of wireless sensor networks, a scheme to construct networks hierarchically has received considerable attention among researchers. Researches on the methods to construct wireless networks hierarchically have been conducted focusing on how to select nodes such that they constitute a backbone network of wireless network. Nodes comprising the backbone network should be connected themselves and can cover other remaining nodes. A problem to find the minimum number of nodes which satisfy these conditions is known as the minimum connected dominating set (MCDS) problem. The MCDS problem is NP-hard, therefore there is no efficient algorithm which guarantee the optimal solutions for this problem at present. In this paper, we propose a novel multi-start local search algorithm to solve the MCDS problem efficiently. For the performance evaluation of the proposed method, we conduct extensive experiments and report the results.

Entani and Tanaka (2007) presented a new approach for obtaining interval evaluations suitable for handling uncertain data. Above all, their approach is characterized by the normalization of interval data and thus the elimination of redundant bounds. Further, interval global weights in AHP are derived by using such normalized interval data. In this paper, we present a heuristic method for finding extreme points of interval data, which basically extends the method by Entani and Tanaka (2007), and also helps to obtain normalized interval data. In the second part of this paper, we show that the solutions to the linear program for interval global weights can be obtained by a simple inspection. In the meantime, the absolute dominance proposed by the authors is extended to pairwise dominance which makes it possible to identify at least more dominated alternatives under the same information.

The purpose of this study is to analyze the spatial structure of laboring classes in Manchester in the 19th century. Manchester had districts where laboring classes lived in destitution. Elizabeth Gaskell's Mary Barton demonstrates the miserable state of laboring classes by depicting their small, dirty living residential spaces. Engels's The Condition of the Working Class in England analyzes the laboring classes in industrial areas in England, especially Manchester. The laboring classes' districts formed in a set pattern were separated from the area for bourgeois. It lied in the old district near commercial areas, while upper classes were outside areas. It was the dominant ideology that drove the transformation of Manchester as an industrial city characterized by separation.

The research focused on the return of class analysis of the media soctor. It is told that class is a determining factor of media industry. This article is divided in to four sections that represent class analysis of media. In this study, I claimed that class analysis is necessary of understanding the nature of media industrial capital and its nature. With their domination of the media, big corporations seek to control political power and information. This article has demonstrated that the media power of corporations should be curved.

이 논문은 대한민국의 주식시장에 상장한 기업의 지배구조 분석을 위해 대주주가 어떠한 형태로 주식을 보유하고 있는지에 대한 네트워크 분석이다. 분석대상은 주식시장에 상장한 기업과 그 기업의 주식의 대주주 데이터를 모두 수집하였다. 이를 기업과 대주주 행위자 간에 주식을 보유하고 있는 네트워크를 분석하여 그 보유형태의 의미를 파악하였다. 분석결과 네트워크 형태는 크게 '전체분석, 산업분석, 군집분석, 상장기업분석, 대주주분석, 계열사 분석' 여섯 가지이다. 네트워크 분석결과 주식시장은 전형적인 척도 없는 네트워크 형태를 나타내었으며 반면 그룹간의 계열사 네트워크는 전형적인 계층구조로써 좁은 세상 네트워크의 사례를 나타내었다. 따라서 투자 성향이 갖거나 대주주 간의 이해관계가 있거나 투자상품들이 포트폴리오로 조합원 경우 대주주 간의 네트워크가 밀집된 것을 확인할 수 있었다.

Relying on the interaction indices - dominance index, relative strength index and entropy index, this paper analyzes the structural features of urban network in the Seoul metropolitan area with the flows of commuting, business, and freight. Analytical results show that the Seoul metropolitan urban system is vertical, size-dependent, one-way, and the highest city-dominant network rather than horizontal, size-neutral, two-way, complementary one. The network of freight flow is a little bit more symmetrical than the networks of commuting and business. However, the interaction with Seoul is still determinant in all aspects of hierarchical structure, relative strength, and symmetry of flow.

The study aims to investigate women's clothes described in Gilsang-Cheonyeo-Sang in Nara period of Japan to gain a clear understanding of the clothes of the ruling class women at that time. Gilsang-Cheonyeo-Sang was made in Nara period of Japan when Japan sent envoys and students to Tang, a dynasty of China, to acquire advanced civilization. At that time, Japan also fostered a strong international culture through the exchanges with neighboring nations. With this inflow of continental culture, Japan was dramatically advanced politically, socially, and culturally. The analysis of the clothes of Gilsang-Cheonyeo-Sang showed that she had her hair decorated with Bogye. She wore Ungyeon, Baeja, Daesui, and Tongsui as for her upper garment and Gun, Seub, and Peseul as for her lower garment. She also wore Bidae and Youngeon and put on Geummal and Seok on her feet. Overall, these results suggested that she wore Chinese style clothes. The clothes of Gilsang-Cheonyeo-Sangwere very similar to formal dresses of high class women described in Yangroryeong. Some of her clothes were not shown in Yangroryeong because those clothes were added after Yangroryeong. Another reason may be due to the fact that generalized clothes could be worn even though those clothes were not described in the dress code. In conclusion, the clothes described in Gilsang-Cheonyeo-Sang suggest that they were based on the dress code of Nara Period of Japan while there were also some variations due to the cultural circumstances at that time.
