Since the advent of digital games with hardware development a key component of the game characters are changed to retard the rate at which types of users based on their favorite theory of human proportion. Many popular to gamers in the game according to the change in the retard rate in a unique image of the character. Studies on the head and body proportion are thought that up to now been insufficient. The purpose of this study is to examine a fundamental human proportion that has importance as a molding factor in the game character development, it investigated the characteristics of the game character, and classifying the retard rate of the game character, through the research method of analyzing the results, into the retard rate look for and investigate studying the effect on future game images. Five types of game characters that make up the analysis were analyzed with a unique image, and the more specialized users prefer retard rate, the figurative exaggeration to retard rate than the actual main body. Utilizing a bit exaggerated the difficulties of the character looks relatively small proportion character in the graphic wallpaper increased visibility. The proportion of a game character through the study is considered as a very important factor as the game image in the game development.

The spin states of asteroids is regarded as an important clue to understand not only the physical property of an individual object but also the dynamical evolution of the of the population as a whole. Single asteroids can be broadly classified into two separate groups according to their rotational states; Principal Axis (PA) and Non-Principal Axis (NPA) rotators. To date, lightcurve observations have been carried out mostly for PA asteroids. However, discovery of NPA objects has recently been increased due to new observing techniques, and this is the reason why rotational properties of NPA rotators became an issue. As a DEEP-South pilot study for NPA, we selected two targets, 5247 Krolv (1982 UP6) and 14764 Kilauea (7072 P-L) considering their Principal Axis Rotation (PAR) code and visibility. Observations were made between Jan. and Feb. 2016 for 17 nights employing Korea Microlensing Telescope Network (KMTNet) 1.6 m telescopes installed at SSO and SAAO using DEEP-South TO (Target of Opportunity) mode. To obtain lightcurves, we conducted time-series photometry using Johnson-Cousins R-filter. Multi-band photometry was also made with BVRI filters at the same time, for taxonomy. Their preliminary lightcurves and approximate mineralogy will be presented.

The multilateral attempt for present applications of art school of thought and expression is leading modern fashion as a chapter of various artistic expression. In fashion, historic art thinking which predominated the period are source of optional inspiration not simply being generated, culminated and disappear but layout principles which can reemerge as periodical needs. In other words, the past styles are the source of inspiration of new trend of the present time and will serve as the text that give birth to yet another trend. In this study, I conducted the research on the layout principles of Modernism Architecture in aspects of pure visibility and the layout characteristics. And I analyzed cases of modern fashion which were appling architectural layout principles in the view point of formal construction dimension. As the result, the layout principles of Modernism Architecture have the characteristics of diagram linearity, geometric planarity and exclusive closing. And I was applying the architectural layout principles of Modernism to fashion. The layout principles of Modernism Architecture have the tendency of lacking history types, abstract plane partition and reductionism purity in fashion. The meaning of this study is follows: The characteristics of art school of thought are given shape by appling & analysing the architectural layout principles of historical art school of thought to modern fashion in the view point of formal construction dimension. The applied possibility of historical art school of thought as the source of inspiration about the fashion design is extended.

This study conducted a questionnaire survey on the real condition of clothing with focus on related to general motorcycle wear and motorcycle jacket targeting a quick service carrier affiliated with a quick service business in Seoul. In addition, this study is aimed at providing basic data on developing the motorcycle jacket, whose motional flexibility, safety and functionality are excellent, exclusively for a quick service carrier by grasping inconveniences and problems and deducting improvements on the basis of the questionnaire survey. This study, on the basis of the questionnaire survey results, grasped the general part related to quick service and motorcycle wear, such as their general matters, whether they were having on the motorcycle wear in the middle of doing business, whether it's necessary to wear the motorcycle wear, where they had a driving accident, and kinds of external injuries, etc. From the gathered results of analysis of the collected questionnaires, the item which got the lowest satisfaction was the inconvenience from the chafed front neck when driving. Besides, the results showed carriers' complaints like the elbow part felt tight, discomfort in the horizontal movement of the shoulders or back, and wind admission in between zippers. In addition, the respondents showed complaints in the item about hygroscopic property and air permeability at the armpits and back part, and 5 items about material flexibility, wind shielding property, living water repellency, weighty sensation, and night visibility were found to be low in respondents' satisfaction.

This study is to improve the design of bus transfer information that can be substantially used. This study has been processed using the following steps. First, I tried to define the information design and way-finding information design. Secondly, I have researched several case studies, and considered solutions. Finally, I evaluated way-finding maps through pair-wise comparisons, and drew needs through an interview. As the result of this research, there were some problems in font size, improper space between letters and non-consistent information. To solve these problems, the information has to be clear using easy symbols to be well-recognized by citizens. Also, the font size needs to be decided by a calculation of minimum legible size of letters. Lastly, a value contrast between a background color and a letter color needs to be applied more than 70 percent for better visibility. The study is expected to be used as a reference which helps informational design to be developed.

This report summarizes the results of MODTRAN model that are used for the calculation of input radiance of the KOMPSAT-2 Multispectral Camera (MSC). We have calculated the input radiances for four months: January 15, April 15, July 15 and October 15. Annual averages are the arithmetic mean of results from four months. We used the mid-latitude winter and summer for the month of January and July, respectively, while US standard atmospheres are used for April and October. The orbital characteristics of KOMPSAT-2 and the seasonal variations of solar zenith angle over the Korean peninsula were incorporated as inputs to the model. The tropospheric aerosol extinction (visibility = 50 km) was assumed. The surface albedo used in the model calculation represents the global annual mean clear-sky albedo. MSC contract values are found to be considerably greater in the MSC spectral range than the total radiances calculated with the above general conditions. From these results, it can be inferred that the forthcoming MSC images would be somewhat dark. We certainly need a countermeasure for this issue.

The research made a study of the spatial characteristics of $m\'{e}diath\'{e}ques$ based on the twelve case studies of the BMVRs constructed with the financial support of the government since 1992 in France. The $m\'{e}diath\'{e}que$ is the community center for local residents to collect information, to have relationship with others and to shape public opinions. Thus it should have easy accessibility, liberal flow plan and the diversity of the newest information. The architectural elements to offer these faculties are summarized as follows. Firstly, the $m\'{e}diath\'{e}que$ as the public facility should have the easy flow plan and the high recognition for visitors. Second, it should be the efficient space for both managers and visitors. thus, it should not need more managers or have the difficulty to move. Third, it should be planed to support the change of the form of information and the needs of the visitors. It, therefore, should have the wide space with no wall and divide the space by movable furnitures. Lastly, it should be the space with the natural light, and it does not need the special artificial lights like museums. It is considered that the planning of the $m\'{e}diath\'{e}que$ should be from the four principles. Additionally, the program of the $M\'{e}diath\'{e}que$ should reflect the each local traits.

In case of a fire in road or railway tunnel it is always necessary to keep the escape condition as good as possible. Most of the victims of major fires in tunnels are because they couldn't leave the tunnel in time and were trapped by smoke, or rescue teams couldn't reach the place of the accident due to low visibility and high temperature. In spring 2003 a comprehensive field experiment was undertaken in a large scaled tunnel in Youngin City to test the effectiveness of a new water spray curtain system, designed to the air qualify inside of a tunnel in case of fire during passenger's escape to safe routes, In order to control the smoke propagation, fixed water sprayed nozzles were used to make water curtain system, which can be installed or hanging water piping line below ceiling. The experiment was accompanied by an extensive measurement campaign in order to measure temperature dropping effect and flow conditions as well as CO concentration for various water sprayed curtains produced by sprinkler heads or water spray nozzle. Eventually comparison analysis were undertaken to investigate the performance of water curtains under fixed water pressure. Therefore most effective water curtain system was presented on the basis of water droplet size in long tunnel.

A wiper is a safety device removing rain and debris from windshield and ensuring visibility of drivers. If contact pressure distribution between rubber of the blade and the windshield is unbalanced, unwanted noise, vibration, and abrasion of the blade can occur and sometimes fatal accidents could occur. To improve the safety of the wiper, there have been many researches on the contact pressure analysis of the wiper, but the analysis results were not converged or require much computational time due to material nonlinearity of the rubber and contact conditions between the blade rubber and the windshield. In this research, a simple model with 1D beam and 2D shell elements was used for the contact pressure analysis instead of the 3D blade model. The simplified model saved computational time of the analysis and resolved convergence problems. The accuracy of the analysis results was verified by comparing them with experimental results for different rail spring curvatures.
