Now days, heavy storm occur to be continue. It is hard to use before frequency based on flood discharge for decision that design water pocket structure. We need to estimation of frequency based on flood discharge on the important basin likely city or basin that damage caused by flood recurrence. In this paper flood discharge calculated by Clark watershed method and SCS synthetic unit hydrograph method about upside during each minute of among time distribution method of rainfall, Huff method choosing Bocheong Stream basin that is representative basin of International Hydrologic Project (IHP) about time distribution of rainfall that exert big effect at flood discharge estimate to research target basin because of and the result is as following. Relation between probability flood discharge that is calculated through frequency analysis about flood discharge data and rainfall - runoff that is calculated through outward flow model was assumed about $48.1{\sim}95.9%$ in the case of $55.8{\sim}104.0%$, SCS synthetic unit hydrograph method in case of Clark watershed method, and Clark watershed method has big value overly in case of than SCS synthetic unit hydrograph method in case of basin that see, but branch of except appeared little more similarly with frequency flood discharge that calculate using survey data. In the case of Critical duration, could know that change is big area of basin is decrescent. When decide time distribution type of rainfall, apply upside during most Huff 1-ST because heavy rain phenomenon of upsides appears by the most things during result 1-ST about observation recording of target area about Huff method to be method to use most in business, but maximum value of peak flood discharge appeared on Huff 3-RD too in the case of upside, SCS synthetic unit hydrograph method during Huff 3-RD incidental of this research and case of Clark watershed method. That is, in the case of Huff method, latitude is decide that it is decision method of reasonable design floods that calculate applying during all $1-ST{\sim}4-TH$.

Contemporary young people reveal their own personal values through the fashion that creates visual looks. Since 2000s began, young generations who are self-centered, value their own personality and constantly seek for changes form the main axis of fashion. In particular, the lower half of the body that has begun to be exposed outward has become the region that they want to expose as more ideal region than the upper half of the body. Further, young generations always have interest in fashion, and female college students in their early 20s are regarded as the group that values the aspects of pleasure that involve clothes and tends to seek sensibility when purchasing clothes. With this background, this study aims to examine how the styles that apply to modern fashion and recent vogues are evaluated with a focus on skinny jean from jean pants styles preferred by female college students. Materials regarding theoretical background and photos were collected from fashion related magazines at home and abroad and from the Internet websites. Questionnaires were surveyed for 160 female college students aged 20 or 25 who live in Seoul, and the results show as follows: Many female college students enjoy skinny jean and follow the fashion. However there are consumers who cling to their own styles even in the fashion of skinny jen. Ironically, some consumers wear it although they consider it as an item that does not fit Koreans: they tend to consider perspectives from others rather than their own preferences. For example, they wear it in order to show it to their boy friends or because they want themselves to look slim. In addition consumers seem to use Dongdaemun Shopping Mall or Internet shopping malls that provide various and low-priced items rather than to use high-priced famous products. It is considered that this result is shown as above because the scope of the study was restricted to female college students in their 20s. Accordingly, it is suggested that further studies should extend their subjects to wider range of ages.

The purpose of this study is to conduct a questionnaire survey on the actual conditions of the working uniform and protective equipment put on by street cleaners, then to identify their inconvenience and problems and to draw solutions to improve them, and finally to design a spring-and-autumn street cleaner uniform which has enhanced functionalities such as motional flexibility, safety and soil proof. The questionnaire survey of this study was done by street cleaners who were in charge of street cleaning and collecting the recyclable waste. The result of this study, easily worn-out parts of the working clothing were the sleeve hems and the front part on the upper uniform, and the trouser hems and zipper on the lower uniform. Easily soiled parts were the sleeve hems, parts of arm on the upper uniform, and the trouser hems and knee parts on the lower uniform. Based on the results of the questionnaire survey, the sample uniforms were designed in consideration of material, design and pattern. A soil-proof material was used for easily soiled parts such as sleeve hems, knee parts and trouser hems. Reflective material was applied to the parts such as chest, back and the side lines of sleeves and trousers to raise visibility in working and to ensure safety. A crease was given to each side of the back. The height of sleeve cap was lowered to lift the motional flexibility of back and arm parts. Darts were applied to elbow and knee parts for a three-dimensional design. Gussets were inserted in the thigh part to give it activity. Then quantitative evaluation and a sensory evaluation, which was composed of outward appearance, motional flexibility and fitness for field operation, were conducted. According to these evaluations, the sample uniform was found to be more satisfactory than current uniform.

The objective of this study is to predict the minimization effect of the noise and vibration during the construction and the train operation regarding to the design modification of the Taegu Subway Line No. 1. It was suggested optimal control blasting methods to reduce the causing vibration Nuance to the resident in City Taegu and also proposed the better governing method to decrease the environmental hazard to the near buildings and residents during the train operation. When the high-density gaseous reaction of explosion products exerts a high pressure in motion outward, a dynamic stress field will be created in the surrounding buildings. Therefore, in the region close to the charge, permanent damage begins to occur at a great critical level of partial velocity, that is difficult from different structure as working conditions. It is reliable to predict that the damages could be reduced if we know the peak velocity and the exact reasons through the conducting of detail studies of structural analysis of the related buildings with the optimal blasting designs. A blasting technique should be deemed to take advantage of the reduction of damage of the surrounding rocks and structures to improve the in-city blasting. This is a typical in-city blasting operation where success depends on closely controlling the ground vibrations in case of better designed blasting methods. There are techniques that can be applied to prevent large vibrations from damaging the important buildings through the Route Modification of the Taegu Subway Line No. 1.

This study examined the effect of media involvement on appearance evaluation, appearance stress, and appearance management behavior. Data were collected from 315 female university students in Daejeon and Chungnam from May to June 2013. Data were analyzed by descriptive statistics, t-test, path analysis using the SPSS-WIN 20.0, AMOS 20.0 program. The results of this study were as follows. First, media involvement were classified into low and high groups. There were significant differences in appearance evaluation by level of involvement. The low group of media involvement indicated a more positive appearance evaluation than the high group. Second, there were significant differences in the appearance management behavior by level of involvement. Third, media involvement directly affected appearance evaluation and appearance management behavior. Appearance evaluation affected appearance stress and appearance management behavior. This study verified the structural relationship of media involvement, appearance stress, and appearance management behavior as outward behavior variables.

The purpose of this study is to find out understand the resident's subjective responses to physical indoor environment. The questionnaire survey was carried out to measure form Jan. 8th to Feb. 2th in 1996, the typical external climate of winter in Korea. The subjects were four hundred and eleven housewives, living in apartments of RC structure I Ilsan apartment complex. As the result, residents usual ventilate once or twice a day by opening outward windows for about ten minutes. Unpleasant smell producted by cooking and wet garbage made most of them negatively respond to kitchen's air quality. regression analysis of relativeness between sense of air freshness smell, dust and comfort revealed that sense of comfort was the most highly related with the extent of bad smell. Housing factors such as size of apartments and ventilating, smoking and gas usage had significant effects on indoor air quality and the subjective responses in winter. Therefore it is especially important to consider air pollution problem from the beginning stage when planning small apartments. It is required that the government of environment has to emphasize the importance of ventilation to residents, and makes an effort to establish the design criteria on indoor air quality in house.

In many very high density cities in Asia in which there is limited area to expand, growth is forced upward as well as outward. Densely packed detached houses and low-rise buildings are replaced by lower density high-rises, leaving open spaces between high-rise buildings. Through this process, areas that formerly did not have much green space gain valuable green spaces, and new ecological corridors and patches are created. In this study, the demographic and housing-type changes of Wonju City were delineated using land use maps, aerial images, census data, and other administrative data. Green area changes were calculated using land cover data derived from multi-year Landsat TM satellite imagery. The values were then compared against demographic and housing-type changes for each administrative unit. The overall results showed a decrease of forested area in the city and an increase of developed area. Urban sprawl was clearly visible in many of the suburban areas. However, as expected, we also detected areas in which greenness did not decrease when the population greatly increased. These areas were characterized by residential building complexes of ten or more stories. If an equal number of housing units had been built as detached houses, these areas would not have kept as much green space. Our research result showed that high-density and high-rise residential structures can offer an alternative means to protect or create urban green spaces in high-density urban environments.
