Generally, there are two methods which generates the base map of Geo-Spatial Information System(GSIS). one is the digitizing of existing map, and the other is the analytical plotting method editing data acquired by sensors using computers. But the analytical plotting method and method of the digitizing of existing map is technically complex and has the disadvantages in the costs and time. The subject region of study(the Kwangyang province), was photographed by aircraft, and photographing scale was 1/6,000. Then this area was divided into two specific regions, the residential area, and the agricultural area. In this study, we developed the algorithm that generated base map of database in GSIS from the aerial photo. This algorithm is as followed. First, the digital aerial photos were generated using these aerial photos. Second, these digital aerial photos were enhanced by implementing the histogram equalization. Third, the objects of the enhanced images were extracted by implementing thresholding and edged detection techiques of image segmentation. Finally, these images could be used to updated the base map of database in GSIS. The result obtained from this study showed that method used by this study were more efficient than existing method in costs and time.

The analysis on the characteristics of the signification system of Japanese feature-length animations that this essay centrally deals with eventually examines the characteristics of representation and communication in Japanese feature-length animations. In general, most animation works focusing on characters and stories contain the signification systems related to 'denotation' and connotation.' However, tendency of the aesthetic representation and communication that appears differently, depending on the characteristics of the signification system that each animation work pursues. From this point of view, Japanese feature-length animation emphasizes connotative signification system and aesthetic representation, unlike Disney animation that strongly shows the tendency that makes the audience directly immersed in the theme and message of the work conveyed further in the myths by pursuing denotative signification system. And, in the case of Japanese feature-length animation, the 'dissenting and arbitrary interpretation' of the theme, the message that the animation work intends to convey and myths pursued is bound to appear diversely, depending on the audience's experiences and cultural and social backgrounds.

Semiotic theory plays a vital role in the cognition of realistic films. Realistic films aim to reflect events and situations in real life, and arouse the audience's thinking about real problems through realistic depiction. In this process, the theory of semiotics helps to reveal the symbolic elements in the film and the profound meaning behind them. This study focused on the realism movie 도 가 니 "(Silenced), on the basis of the theory of saussure's semiotics, combined with its proposed the concept of "signifier" and "mean", through the study of arbitrariness and secondary film symbol sign system, designed to dig deeper into the symbolic meanings in the movie, and their cultural significance and social evaluation. By analyzing the implied narrative structure, meaning structure and ideology in the film, this paper probes into the influence and effect of mass culture on society and reveals the potential information conveyed by symbols in the film. This study aims to provide creative insights and explanations to provide useful references for research in related fields.

노면배수 시설의 설계를 위하여 부등류 해석을 기반으로 한 설계모형을 수립하고 등류 해석을 기반으로 한 설계결과와 비교하였다. 노면배수시설을 설계하기 위해서는 지속시간을 가정하여 설계강우를 결정하고 설계변수인 유출구 간격을 가정하여, 호우에 응답하여 발생하는 홍수의 도달시간이 가정된 지속시간과 유사할 때까지 계산을 반복하여 유출구 간격을 결정한다. 부등류 해석에 의한 수로 흐름 해석은 수로 양단에 유출구를 갖는 수로의 분수계의 위치를 결정하는 과정과 발생하는 최대수심이 허용수심을 초과하지 않도록 수로길이를 산정하는 과정을 포함하므로 등류 해석에 비해 계산과정이 복잡하게 된다. 가상의 노면배수 체계를 설정하고 다양한 수로경사에 대해 노면배수 설계모형을 적용한 결과, 등류해석의 경우 유출구 간격은 수로경사가 증가할수록 증가하였지만, 부등류 해석의 경우 수로경사가 증가할수록 감소하였다가 다시 증가하는 경향을 보였다. 수로경사가 작은 경우 등류 해석보다 부등류 해석을 기반으로 노면배수 시설을 설계하는 것이 합리적인 것으로 판단되었다.

This study is intended to propose a system reliability analysis model for R.C. bridge superstructures based on the systems reliability theory. Approximately assuming that the ultimate capacity of the superstructures is reached, when two adjacent girders fail subsequently, a practical system reliability model is proposed, which is based on a point estimate for Level II parallel-series system modelling. The sensitivity analysis of system reliabilities for the variation of the coefficients of correlations between the failure modes is performed by applying the proposed model for R.C. T beam bridges. It is observed that the point estimate method for the proposed model corresponds to the average value of the Ditlevsen's bound, and the system reliability index, ${\beta}_s$, varies quite sensitively according to the variation of the cofficients of correlations. Systems reliabilities of a few existing T beam bridges are analyzed by applying the proposed practical system reliability method of this study, and, in addition, the preferable direction of the development of the reliability-based code calibration using the system target reliability index concept are suggested.

This study aims to find out the construction process and planning characteristics of Suwon and Hwa-sung in 18th century from the point of water system. This study has an explanatory approach. The planning intents in the water system was driven out by analyzing various planning elements in relation to water system in the process of constructing Hwa-sung in 18th century. Using Entire Map of Hwa-sung, land registration map made in 1911 and topographic map of 1/10,000 scale made in 1917, water system and interpretation of spatial structure in Hwa-sung were analyzed. The results are as follows(Planning characteristics of the water system in Haw-sung in 18th century are as follows). Firstly, in determining the spatial structure and location of Hwa-sung, water system had an important role. Secondly, integrated drainage system was planned by the organization of natural and artificial water stream. Thirdly, the main street system and land use structure were planned in relation with water system. Fourthly, territoriality of main area was planned with water stream. Fifthly, ponds were constructed for flood control and they had important role as landscape elements. Sixthly, water stream was used as intentional BiBo element. As a result of the study, the weater system of Hwa-sung in 18th century was planned by the organization of natural and artificial water stream in relation with the location of new town and wide area's spatial structure, street system, land use structure, territoriality of main area, terriflood control, water quality protection, landscape, 비보 and urban daily life.
