For the past few years, the video surveillance market has shown a rapid growth due to the increasing demand for Closed Circuit Television(CCTV) by the public sector and the private security industry. While the overall utilization of CCTV in the public and private sectors is expanding, its usage in the field of disaster management is less than sufficient. Therefore, the authors of this study, in an effort to revisit the role of CCTV in disaster situations, have carried out a case analysis in the vicinity of the Gangnam Station which has been designated as a natural disaster-prone area. First, the CCTV images around the target location are collected and the time and depth of inundation are measured through field surveys and image analyses. Next, a rainfall analysis was conducted using the Automatic Weather Station(AWS) data and the past inundation records. Lastly, the authors provide an estimate of rainfall for the areas around the station and suggest viable warning systems and countermeasures. The results from this study are expected to make positive contributions towards a significant reduction of the damages caused by the floods around the Gangnam Station.

Geo-spatial information system covers a wide range of applications and technologies and is of great potential interest to many users in government, industry and science. In many civil engineering problems it is necessary to model a landform in order to be able to removed or to be brought in to make the site ready for the proposed developed. The earthwork volume, could be calculated by the trapezoidal formula, Simpson's 1/3 and 3/8 rules. And slope is defined by a plane tangent to the surface as modelled by the digital terrain model at any given point and comprises two components namely, gradient, the maximum rate of change altitude, and aspect, the compass direction of this maximum rate of change. The thesis is the earthwork volume could be counted, readjustment height, slope and aspect analysis of various derived products can be obtained form geo-spatial informations.

As the map paradigm shifts from analog to digital, the LOD (Level Of Detail) of spatial information needs to be redefined. In this study, we propose 4- dimensional indoor LOD model which can be used in digital map environment. For this purpose, the limitation of the previous research is derived through study of related works, and based on this, four different LODs are defined such PLOD (Position accuracy LOD) based on position accuracy, GLOD (Geometric LOD) based on shape representation, CLOD (Complete LOD) based on generalization, and SLOD (Semantic LOD) based on theme accuracy. In addition, we describe the relationships among the four different LODs, and explain how to express the indoor LOD using the four different LODs and show examples. In the future, the case studies of indoor LOD adoption for various indoor services and the study of method for applying CLOD and SLOD to each feature should be performed to verify the feasibility and validity of proposed indoor LOD.

Game industry demands for talented workers from game scenario writing, graphic design and computer game programming areas, which are the three heterogeneous parts of computer game making. This paper deals with the analysis on the college convergence education, surveying the curriculums of game departments in Korean universities and with how to proceed for game programmers to the direction of convergence education for computer game making. Most of the game departments are focusing on game programming area, whereas only 2 departments among 14 surveyed are teaching the game graphic design topics. Observing the curriculum changes for sampled game departments reveals that around 30% of the majoring classes are directly game related. Game programmers are to be advised to fulfill their programming skill first and later expand their ability to game graphic design skill.

The research of the current situation of made-to-measure production by ready-made men's suit companies was done by interviewing and surveying the made-to-measure specialists. It was apparent that most frequently purchased items in Mass Customization were jackets of formal dress. The results of the research on the current situation of Mass Customization by ready-made clothes companies were as follows. The Mass Customization accounted for 3∼10%. The advantages of Mass Customization were more acceptable sizes, designs and details while the initial reasons for it were unusual physical figures and designs. The posture of a customer during measuring turned out to be critical enough to influence fitness after production. The companies in the research were found out to have materials for Mass Customization in storage and the sizes and other data of fixed circle of customers who would want Mass Customization saved in computer in most of the cases.
