Cycling has become a popular leisure activity, and many cycling enthusiasts have used cycling clothes as a form of expression, which often comes in wide range of colors. The study shows the importance of color in cycling clothing to meet the emotional needs of consumers. Furthermore, this study aims to provide comparative analysis between color of domestic and overseas cycling clothing brands, and color preference of Korean consumers in order to provide data, which can be used in satisfying consumers' needs for personal expression and emotional demands. Thus, the study expects to identify consumers' satisfaction for cycling clothing. The consumers were categorized by the frequency of cycling and their interest in fashion, and the following categories were made:potential consumers, casual cyclists with low fashion involvement, casual cyclists with high fashion involvement and frequent cyclists with high fashion involvement. Consumers preferred dark colors for their cycling clothing including jacket, top and pants, while 'frequent cyclists with high fashion involvement' preferred more diverse colors and tones. In the cycling clothing market, white and black were major colors, while red, orange and blue were major colors of chromatic color. In terms of shade, dark shade dominated the market. Comparing between preferred color and preferred product color, black was preferred for both, but no other colors showed such tendency. This study is based on empirical analysis and verification of color, which is the emotional element appealing to specific and segmented sports-apparel market. The study revealed that the data could be applicable to the design of future products.

A social phenomenon that occurs in a physical space is said to be a complex system. However, space syntax, which is commonly employed by researchers to identify such social phenomena, has various limitations in interpreting their complexity. On the other hand, agent-based modeling considers a variety of factors including the personality of the agent, objective-oriented work flows, estimation according to time flows and better prediction of space use through diverse parameters depending the situation, as well as the characteristics of the space. The agent-based method thus has the potentials to be developed as an alternative to space syntax techniques. In particular, discrete event driven simulation(DEVS), which is part of the agent-based modeling method, embraces the concept of networks just like space syntax, which allows a possible theoretical linkage in the future. This study suggests a procedural model of agent-based DEVS reflecting two different connection methods, i.e. connections between adjacent areas and those of the entire space, and attempts to identify the relationship between the local and regional indices of space syntax. A number of spaces were selected as examples-one for a preliminary experiment and eight modified for the main experiment-and space syntax and DEVS were applied to each of them. The comparative analysis of the results led to the conclusions as follows: 1) Adjacent connections were closely related to local indices, while the whole-space approach to regional indices. Local integration shows both characteristics. 2) Observation of the time flow model indicated a faster convergence with the range of 1 to 3-fold of the total time of one lap, with the error of less than 10%. 3) The heat map analysis showed more obvious characteristics of using the space for the entire space rather than adjacent connections. 4) Space syntax shows higher eligibility than ABM.

본 논문에서는 지반 하이브리드-온라인 시뮬레이션의 방법을 압밀 해석에 적용하기 위한 시도를 수행하였다. 일반적인 수치해석법이 실내시험을 통해 얻어진 흙의 구성모델을 이상화시켜 사용하는 것과 달리, 이 방법에서는 흙의 거동을 요소시험체로부터 직접 도입해가면서 해석을 수행한다. 그러므로 복잡한 파라미터의 평가과정이 생략될 수 있게 되며 인위적 이상화에 의한 해석 오차를 경감할 수 있게 된다. 본 논문에서는 실험장치의 물리적 성능을 검증하기 위하여 단계압밀시험과 투수시험(CONPERM test)을 수행하여 제어와 계측의 결과를 고찰하였으며, 시스템으로부터 얻은 데이터의 건전성을 평가하기 위하여 검증해석을 수행하였다. 결과적으로, 본 연구를 통해 개발된 하이브리드-온라인 압밀해석 시스템은 재성형된 카오리나이트의 압밀거동을 모순없이 재현하고 있음을 알 수 있었다.

Objectives : Sweet bee venom is made by removing allergen from the bee venom through gel filtration chromatography and propionic acid/urea polyacrylamide gel electrophoresis. The aim of this study was to verify allergy inhibitory action in Sweet Bee Venom in which the allergy causing enzyme is removed. Methods : 95 healthy adult men and women were selected through a survey whom had never received the bee venom therapy in the past. The concentration of bee venom pharmacopuncture and Sweet BV pharmacopuncture was equally at 0.1mg/ml and the experiment was conducted as the double blind test. Experiment groups were classified into low dosage groups(0.1ml for both bee venom pharmacopuncture and Sweet BV) and high dosage groups where 0.4ml of respective administrations were rendered made observations for allergic responses. Results : Participants of the study was comprised of 71 men and 24 women with the average age of 29.0 years. According to results of the low dosage groups, Sweet BV group showed significant reduction in pain after 4 hours and 24 hours compared to the bee venom pharmacopuncture group. Other allergic responses were insignificant between the groups. For the high dosage groups, Sweet bee venom group showed reduction in pain after 30 minutes and 4 hours. Other allergic responses such as edema, itchiness, dizziness from hypersensitivity, and fatigue were significantly lower in the Sweet bee venom administered group after 30 minutes. Conclusions : As a result of removed allergen, Sweet bee venom significantly inhibits allergic responses both locally and throughout the body. This indicates wider and easier application of Sweet bee venom for the symptoms applicable to the bee venom pharmacopuncture. Further comparative studies should be conducted to yield more objective verification.

The purpose of this study is to examine green consumer behavior (green product purchasing behavior and green consumption life) affected by demographical characteristics, and cognition degree of green life (cognition of a green indicator, a green life catalyst system, and environmental problems). It's also to promote strategy and suggest effective activation plans for the vitalization of green consumer behavior. To carry out the task, verification of credibility, multiple regression analysis, two-step cluster analysis, and multinomial logistic analysis were used. The results are as follows: First, the factors that effect green product purchasing behavior were gender, age, cognitive of a green indicator, carbon points system, electricity peak hour system, and seriousness of environmental damage due to lifestyle. Second, the factors that effect green lifestyle were gender, age, carbon grade indicator system, cognition of a green system, and the seriousness of environmental damage due to lifestyle. Third, the comparative group characteristic analysis showed low rates for careless green consumer behavior groups compared to the passive green consumer behavior groups in cognition of a green indicator, green system, and environmental problems. For active green consumer behavior groups, the analysis showed high rates in cognition of carbon grades, eco-labeling, electricity peak hour system, and environmental damage due to lifestyle. In order to encourage green consumer behavior, it's evident that cognition of a green indicator, a green life catalyst system, and environmental problems need to be improved through strategic education and continuous encouragement.

In order to improve the functions of libraries in each region, it is necessary to establish the guideline of area of space size according to size and region. Therefore, this study aims to present the guideline of area of space size of public libraries for the revision of the manual of 2013. The study findings are as follows. First, the theoretical and preceding studies have raised a need to present the guidelines on the areas of public libraries nationwide since the guidelines of areas presented in Gyeonggi Province have been derived from the provincial libraries of Gyeonggi only. It is also necessary to analyze and verify the guidelines of areas of public libraries nationwide in Korea based on the guidelines of areas for Gyeonggi Province. Second, I have analyzed the areas of public libraries nationwide. I have conducted comparative analysis and verification in comparison with the areas in Gyeonggi Province through the ${\pm}5%$ error range presented in the existing manual, which has led to the conclusion that the guidelines of areas in Gyeonggi Province are within the error range and thus are applicable to public libraries nationwide. Third, I have presented the five different types of guidelines of areas. This study is expected to facilitate accelerating the decision-making and policy establishment as part of the construction and remodeling plans. In the future, however, more detailed studies on libraries bigger than $5,000m^2$ is needed.

Even though fiber reinforced polymer (FRP) has been widely used as a retrofitting material, the FRP behavior and effect in FRP retrofitted structure under blast loading, impulsive loading with instantaneous time duration, has not been accurately examined. The past studies have focused on the performance of FRP retrofitted structures by making simplifications in modeling, without incorporating accurate failure mechanisms of FRP. Therefore, it is critical to establish an analytical model that can properly consider the specific features of FRP material in evaluating the response of retrofitted concrete structures under blast loading. In this study, debonding failure analysis technique for FRP retrofitted concrete structure under blast loading is suggested by considering FRP material characteristics and debonding failure mechanisms as well as rate dependent failure mechanism based on a blast resisting design concept. In addition, blast simulation of FRP retrofitted RC panel is performed to validate the proposed model and analysis method. For validation of the proposed model and analysis method, the reported experimental results are compared with the debonding failure analysis results. From the comparative verification, it is confirmed that the proposed analytical model considering debonding failure of FRP is able to reasonably predict the behavior of FRP retrofitted concrete panel under blast loading.
