Main focus of FPS game's play is securing vantage points in space based on specific theme and removing enemies. It could be more directly interacted with players' game space than other genres. This paper analyzes design patterns on FPS game of nine types consisted of three themes : past war, modern war, near future war, which is based on 10 different patterns of near future theme-oriented by Hullett and Whitehead. As an outcome, an important function of 'element of cover' was found additionally as a main pattern besides the 10 different patterns. And by analyzing its attributes, it is suggested the efficient way to use the 'cover' pattern for level-design. This result can be utilized as an empirical guideline for level-design of FPS games by theme.

The SAR patterns of biological objects contacted with coaxial waveguide antennal has been investigated, in which the biological object was modeled by a homogeneous and four-layered lossy human body. We derived the finite-difference time-domain(FDTD) algorithm and equation of MUR and generalized perfectly matched layer(GPML) ABCs in cylindrical coordination. The coupling between coaxial waveguide antenna and a biological object was analyzed by use of MUR and GPML ABCs in the FDTD method to obtain the absorbed power patterns in the media. The specific absorption rates (SAR) distribution which was corresponding to the temperature distribution was calculated in each region by use of the steady-state response in the FDTD method. The SAR patterns of the FDTD method using MUR absorbing boundary conditions(ABCs) was compared with those of the FDTD method using GPML ABCs. The comparison exhibits that the penetration depth of the SAR patterns using MUR ABCs is deeper than that of the SAR patterns using GPML ABCs because of loss in free space. However, the spread in the lateral directions of the SAR patterns using GPML ABCs is smaller than of the SAR patterns using MUR ABCs.

In this paper, we propose the biomedical spectral pattern classification techniques by the fusion scheme based on the SpPCA and MLP in extended feature space. A conventional PCA technique for the dimension reduction has the problem that it can't find an optimal transformation matrix if the property of input data is nonlinear. To overcome this drawback, we extract features by the SpPCA technique in extended space which use the local patterns rather than whole patterns. In the classification step, individual classifier based on MLP calculates the similarity of each class for local features. Finally, biomedical spectral patterns is classified by the fusion scheme to effectively combine the individual information. As the simulation results to verify the effectiveness, the proposed method showed more improved classification results than conventional methods.

For multivariate datasets with large number of variables, classical dimensional reduction methods such as principal component analysis may not be effective for data visualization. The underlying reason is that the dimensionality of the space of variables is often larger than two or three, while the visualization to the human eye is most effective with two or three dimensions. This paper proposes a working procedure which first partitions the variables into several "latent" clusters, explores individual data subsets, and finally integrates findings. We use R pakacage "ClustOfVar" for partitioning variables around latent dimensions and the principal component biplot method to visualize within-cluster patterns. Additionally, we use the technique for embedding supplementary variables to figure out the relationships between within-cluster variables and outside variables.

The objective of the research is to analyze changing trend of water discharge in precipitation, according to changing land use, through an environment-friendly urban development method called LID. The study chose S1 basin (Separated Sewer districts) in Cheongju region for survey. Among LID methods, relatively more applicable methods of green rooftop space and parking lot with permeable material were selected to construct plausible scenarios. Curve Number (CN) value was calculated due to land use patterns in each scenario, and SWMM model simulation were conducted during 2008 for comparative analysis. For Case 1, only parking lot with permeable material was applied to the scenario. Green rooftop space I and II were applied to Case 2 and 3 respectively. For Case 4 and 5, green rooftop space I and II were applied, in addition to parking lot with permeable material, Calculation of CN value showed that for S1 basin, the value was 88.1 (prior to scenario application), 86.5 (Case 1), 81.9 (Case 2), 68.5 (Case 3), 80.4 (Case 4) and 67.2 (Case 5). Changing pattern of rain water discharge was analyzed for each scenario. For Case 1, the change was not remarkable before and after application of scenario. In Case 2 and 4, the impact of rain water discharge as source of pollutant fell to 20~30%. The rate dropped to 30~50% in Case 3 and 5 respectively. The result demonstrates that the amount of rain water discharge, amount and frequency of sewer overflow, frequency of rain water discharge, and pollution load decreased in accordance with declining CN value in each scenario. In installing green rooftop space, the effect was twice greater when rain water discharge was directly infiltrated into soil.

The purpose of this study is to investigate tendencies on land use in the housing site development district by grasping the characteristics of changes of building use at the borders of single-detached housing area for planning single-detached housing area in the future. It is divided the borders of detached housing areas into three types, educational facility, parks and green spaces, and apartment complex, and then analyzed the characteristics of each location after a field study. It is summarized as follows. First, there were stationery and flour-based meal stores in adjacent borders near educational facilities, suitable for students' interest and motion patterns, and it is required to consider about frequent children's action in the street. Second, there are many facilities for park users and residents, such as educational institutes and restaurants in adjacent to borders near parks. In borders neighboring buffer green belt areas, warehouses and vacant sites were mainly distributed. And the revitalization of streets was lower than others, because a road was used as a parking space. Third, there were realty dealers, food stores, and laundries which provide the dwellers with service in adjacent borders near multi-family housing.

The aims of this study are to establish a mode of housing life style that meet the demands of families living in big cities, and the contribute to the development of a better housing life style pattern by considering metropolitan residents' choice of housing and basic concepts of their behavioral patterns. The results of this study were as follows: 1. Value orientation of family life was divided into value orientation of family and value orientation of housing. Value orientation of family was constituted of four factors such as 'harmony', 'leisure and hobbies', 'individual development and its support' , 'education' . Value orientation of housing is constituted of three factors such as 'physical characteristics of house' , '\`environmental condition', 'socio-economic conditions of housing'. The comprehensive life values were constituted of six factors such as 'the importance of communal family', 'the importance of housing decoration and housing life benefits', 'the importance of security and holding environment' , 'the importance of familial harmony', 'the importance of privacy', 'the importance of convenience and natural environment'. Based on three factors, were found to be fine types of value orientation of family life which were 'pursue healthy of family', 'comfort of family', 'clean environment', 'convenient environment', and 'harmonious relationship among family members'. Variables influencing the value orientation of family life were property and price of housing. 2. Consumption propensity when buying house, furniture and durables were constituted of four factors which were propensity to 'beauty', 'fashion', 'tradition and symbol', and 'pragmatic use'. Based on these factors, there were found to be four types of consumption propensity when buying house, furniture and durables which were 'fashion', 'tradition and symbol', 'beauty', and 'pragmatic use'. Variables influencing spending habits were found to be objective social class (SES), types of residence, wife's educational background, and price of housing. 3. Propensity to using space were constituted of three factors which were 'convenience', 'politeness and social grace', and 'housekeeping'. Based on these factors, there were found to be three types of propensity to using space which were 'individuality', 'convenience', and 'politeness and housekeeping'. Variables influencing propensity to use of space were found to be objective social class (SES), wife's educational background, types of homeownership and price of housing 4. According to this study, there were found to be six patterns of housing life style: 1) family that seeks formalist life, 2) family that seeks harmonious life, 3) family that seeks active healthy life, 4) family that combine various factors, 5) family that seeks convenience, 6) family that stresses environment.

Aprons are popularly used among women for domestic work. They also protect clothes from filth and at the same time become an ornamentation for fashion. Despite their important use at homes and restaurants, beauty parlors, and hotels, little study has been done on aprons. Commercialized aprons do not come in various forms, rather they use the same simple shape with different patterns. There has been no independent study done on aprons, however aprons have been studied as a part of uniform studies in the dining industry by Park and Na(2003) and uniform studies in the airline industry by Lee(2001) and Chung(2001). In this study, the author looked into aprons in accordance to the change of housing space and life style. Not only to be worn in the kitchen, but also to greet guests or for a walk in the neighborhood, the apron needs to have various functions and a trendy fashion. Designs to persue personality and high quality along with functionality and esthetical beauty were developed to present various functions of the apron.

This study attempts to suggest new directions of urban multi-family housing design in the recent era of information, in which the representation of publicity and privacy of the housing reflects new meanings and relationships of the current digital society. The study examines cases of Dutch multi-family housing and investigates the meanings and relationships of publicity and privacy in the building as well as unit design of the housings. Borneo-Sporenburg housing development is a good example that suggests new interpretation and design solution for low-rise, high-density multi-family housing. Thus, this study analyzes street patterns, facade design, and ways of housing unit combination in Borneo-Sporenburg housing and concludes as follows. First, public space in Borneo-Sporenburg housing, which was designed differently from hierarchical and centripetal organization of modern architecture, is divided into small units and spread into the inside, which provides high potential for personal control of space and personal programming of space by space choices. Second, street pattern and facade design of Borneo-Sporenburg housing provide visual publicity and privacy simultaneously as they maintain unity as a whole as well as articulate individual unit in many different ways and provide clues to neighboring. Streets as a public domain have self-controlled boundaries for residents and introduce voluntary use-programs for residents. Third, facades of the housing have no inter-mediate space or common space, and confront streets directly. Space in-between is composed inside the facade and extends into the streets by residents' own choices. Fourth, privacy and individuality of the housing is strengthened. Units of the housing have individual entrances, unique plan type and complicated combination of space that all together emphasize individuality of units, however they are not often notified from the outside.

The purpose of this study is to investigate the environmental value of green space in Seoul. Longitudinal relationships between land use patterns and $SO_2/NO_2$ have been analysed. Then the environmental and economic value of green space were examined. In this study, the following results have been found : Firstly, it was found that the amount of $SO_2$ showed the negative relations with green space but had the positive relationships with the built-up area. Which in turn can be interpreted as securing the green space could improve the $SO_2$ purification capacity. Secondly, Seoul Metropolitan green belt zones absorbed 69,728 tones of $CO_2$, 654 tones of $SO_2$ and produced 51,205 tones of O2 at the year of 1997 standpoint. This results implicate that the Seoul Metropolitan green belt zones resolve 0.2% of $CO_2$ and 2.9% of $SO_2$ production in total. Finally, the occurrence of an additional costs of 6,800 Korean Won per household was expected due to the air conditioning cost increases as the green belt areas decrease. Therefore, it is recommended to establish the alternative plans for the protection and creation of the green space in the urban areas, since those urban green space have the significant meaning as their provision of habitats for the wildlife as well as their contribution to the reduction of energy consumption.
