Yanbian area is a region with great interests to Cultural-Historically Korea as well as China. Cultural-historic study on Yanbian are lots of researches but can find few mapping for sites. This study aimed to make a map and analyze characteristics of distributions in the Cultural-Historic sites of Yanbian using Google Earth. We made a distribution map from stone age to Qing Dynasty. Symbology for mapping made color symbols by time series and categorical symbols. As a research finding, Sites of Balhae and Yuo-Geum age account for large parts in comparison with other ages in Yanbian. Especially, sites of Goguryeo, Balhae and Yuo-Geum age showed spatio-temporal structure of accumulative layers Characteristics of distributions is located in basin and stream area in the early age, and after then historical period moved to hilly sides and mountainous areas. The result of this research is expected to offer information for relevant follow-up studies of Cultural-Historic sites.

This study was designed for a theoretical and methodological discussion on a methodological medium, orality to historicize the 'Civilian Massacre', of countless counter-memories which are inherent in Korean society. In other words, prior to collection of oral sources, it is to produce reliable oral history through a discussion on oral history research methodology and qualitative research methodology of oral history, after theorizing occurrence process of dominant-memory and counter-memory, orality's meanings as a counter-memory and the necessity for historicization of neglected memories, focusing on a 'memory' which is a fundamental background of an 'oral' act. Based on this basic process, oral recording process was performed in Changsoo-myeon, Yeongdeok-gun, Kyung-book Province where was selected as a research target for the civilian massacre that is a case to figure out what kind of high-quality record is produced, with a precise understanding of a particular methodology, oral history.

This study focuses on Korea films of historical communication. Narrative analysis was conducted on the films in 2000s including , and <26 Years> that mainly have dealt with the 'Gwangju Democratization Movement'. As a result of the syntagmatic analysis, these films try to stabilize 'social imbalances' in the aspect of individuals and conceals issues of social structure. In addition, the result of paradigmatic analysis reveals that textual factors of 'active involvement of female characters', 'continuity of history through the survivors' demonstrate its strategies to publicize the historical truth. Consequently these films show its limitations that weakens historical meaning by placing unsolved problems of social structure as well as the love story. But rather than describing it as a history of the past, these films act as a catalyst to bring thins specific historical issue to our present lives and publicize it as a current issue. Therefore, the historical film not only allows current generation to remind to history but also to provide an opportunity to publicize the important issues of social structure in the present society.

It appears that the rapid advance in technology has allowed to broaden the variety of rail systems technology, thereby fostering new business opportunity in rail industry. The direction of rail systems operations is mainly two fold. In one direction, long distance operations between mega cities are pursued with help of high speed trains under development. In the other case, relatively short distance operations for covering intra-city or suburban area are becoming popular. A good example of the latter case is light rail transit (LRT) systems. Due to the short distance operation, it is thus expected that both the development and operation cost for LRT systems be reduced to some extent. The cost reduction desired in there can be gained by scaling down the sizes of both the trains and stations as compared to those of normal rail systems. However, it is not well known how the LRT stations can be scaled down. The objective of this paper is to study on how to slim down the stations (particularly, the functions room) of LRT systems. To achieve the objective, an approach is studied based on a modified method of design structure matrix (DSM). Specifically, using the enhanced DSM method, an integrated architecture is developed for the functions room, in which equipments are housed to perform the functions of electricity, signaling, and communication for LRT stations. The use of the result indicates that the desired reduction can be obtained with the approach taken in the paper.

"한국근대미술의 역사"는 우리 역사에서 자생적으로 근대화 움직임이 일어나던 1800년부터 해방 직후까지 미술에 관한 모든 것을 연대기순으로 정리해놓았다. 이제까지 크고작은 구멍이 많았던 '근대'의 미술은 이 '사전'으로 메울 수 있게 됐다.

In this study, the air quality of underground and overground railway stations was evaluated focusing on the degree of influence of the outside air quality. The measured components were particulate matter ($PM_{10}$), carbon dioxide ($CO_2$), carbon monoxide (CO), nitrogen dioxide ($NO_2$), formaldehyde (HCHO), ozone ($O_3$), total airborne bacteria (TAB), total volatile organic carbon (TVOC), and Radon (Rn), which are included in the maintenance standards and recommended standards of the Indoor Air Quality Management Act. Also, the indoor/outdoor concentration ratios of $PM_{10}$, $NO_2$, and $O_3$ were calculated to estimate the influence of the outdoor air quality. The concentrations of $PM_{10}$ HCHO, TVOC, $NO_2$, and Rn in the underground stations were found to be higher than those in the overground stations. These results indicate that the (present) generation of contaminants are caused by the indoor source of the underground station. The ozone concentration of the overground stations was higher than that of the underground stations, which indicates that the outdoor ozone concentration influenced that of the overground stations directly. Thus, methods of improving the IAQ should take into consideration the types of contamination.

The total number of railroad stations managed in Korea is 322 (including general and wide-area railways), and a considerable number of stations are aging. In terms of the size of the existing railway station and the number of entrances, it has not been possible to secure adequate service capacity, and the demand for station improvement is increasing due to changes in surrounding conditions such as urban development. In the past, railroad stations were focused on the simple function of a connection passage in terms of maintenance or management, but in recent years, railroad stations are also changing to an atmosphere that they should be reborn as a user-centered comfortable, convenient, and safe service provision space. In this study, a case study related to the improvement of the old railway station was conducted to derive an improvement plan that meets the improvement standard of the old station, and the service level evaluation standard was developed. By introducing the concept of service level (LOS) in the development model, station congestion, station movement convenience, and station safety were selected as evaluation indicators. In addition, this development model applied an analytical stratification technique to divide various evaluation elements of each indicator into major and detailed elements and derive the relative importance of the elements by class. Priority for improvement was derived using the ratio of the number of E and F on the LOS for each facility. Based on this study, it is expected to be helpful in using it as an evaluation criterion for improving objective and equitable railway station.
