Objective: The purpose of this study was to evaluate comfort levels of functional and non-functional chairs using subjective comfort rating, interface pressure measurement, muscle activity measurement, and skin temperature measurement. Background: Chairs are used for a prolonged period of time for sitting in many places such as the office, at university, at school, in industry, and so on. Almost all people use chairs in their everyday life. The functional properties of the chair are associated with comfort. Method: The subjective evaluation contains questions regarding chair comfort which can be rated with five point scale. The body-seat interface pressure was measured using a pressure mat system. The symmetry of sitting was measured using electromyography. The change in body part (thigh and buttock) temperature before and after sitting on a chair was measured with an infrared camera. Results: Participants rated significantly (p < 0.05) higher comfort scores for the functional chair in relation to the buttock and thigh region. Also, the participants felt a better cushion effect in the functional chair. When using the functional chair, lower interface pressure, better thermal comfort, and better symmetry of erector spinae muscle activity were observed. Conclusion: Overall, interface pressure measurement, muscle activity measurement, thermal imaging and subjective comfort score results showed that the functional chair was more comfortable than the non-functional chair. Application: The adopted methodologies could be used to measure the seating comfort of train seats.

The purpose of this research is to prepare basic data necessary to develop uniform design by examining the uniforms of Korean and Chinese airline crew. Advanced research, various literature materials related to uniform, as well as a survey on the images portrayed by the different uniforms of the airlines were used as research method, and this was used to investigate its functions and components. The survey was conducted in Incheon International Airport and Gwangju airport from September 1st to 30th of 2013, - targeting 350 people consisting of Koreans, Chinese, and other nationalities who have the experience of using Korean and Chinese aircraft. The research findings are summarized as follows. First, the images of the uniforms were classified into 5 elements: attractiveness, activity, noticeability, femininity, and traditionality. The analysis showed that Korean uniforms, except for Jin Air, received high marks overall, while the Chinese uniforms received lower marks compared to their Korean counterparts. Second, the results were analyzed based on the nationality of the respondents. In regards to Korean airline crews, attractiveness, activity, noticeability, femininity, and traditionality showed statistical significance with Korean respondents, while the significance was seen in attractiveness, activity, femininity, and traditionality for the Chinese respondents. Femininity was the only feature with any significance for the third nation respondents. On the other hand, with regard to Chinese airline crew's uniform, Korean respondents showed statistical significance in the following features: attractiveness and traditionality, while the Chinese and the third nation respondents did not show any statistical significance in any of the elements.

An antiproliferative agent, streptochlorin, was isolated from the fermentation broth of a marine actinomycete isolated from marine sediment. Phylogenetic analysis of the 16S rRNA gene sequence indicated that the strain belongs to the genus Streptomyces. Bioactivity guided fractionation of the culture extract by solvent partitioning, ODS open flash chromatography, and reversed-phase HPLC gave a pure compound, streptochlorin. Its structure was elucidated by extensive 2D NMR and mass spectral analyses. Streptochlorin exhibited significant antiproliferative activity against human cultured cell lines.

The purpose of this study is to propose the design elements useful to give place identity to street space. The theory for place identity is studied and the components-Physical element, Sense, Program, Activity, Context-for identity of place is created. In the case study of SamcheongdongGil, the qualitative research method of Free Picturing Technique and Cognitive Mapping is executed and the samples gathered from the research are analyzed. In the process of analysis, the contents of qualitative evaluation by users is put in order as components for identity of place. Moreover, the design elements for street space are extracted from the case study and theories of urban design. The design elements are summarized as the followings: street pattern with high permeability, various streetscapes, greenscapes, semi public(private) spaces, the third places, public arts, transparent facades, and outdoor activities. Finally, the fruits and boundary of this study are described and the importance of place identity is.

As the interest in internet business increases, effective web site evaluation is in order. While web site evaluation is supposed to be based on feasible applicability and trust-worthy criteria. many researches on web site evaluation fails to rover the various business models and consider corporate-activity-related features. Besides, dealing with the limited aspects such as design and cognitive science is something to be desired on the previous researches. Therefore, This paper presents internet web site evaluation framework not only based on existing researches and analysis but also reflecting corporate strategies. The framework includes web sites contents, design, operation and management-related factors, and it is applied to companies to validate its applicability.

The purpose of this study was to analyze the characteristics of the factor structure in Clothing Silhouette Image and the differences of Image Evaluation related to Grouping of Line and Grouping of Body Emphasis using Silhouette Image Factor and Life Space as variables. Clothing Silhouette Image was estimated by the photographs of 9 Life Spaces ${\times}$ 23 Clothing Silhouettes with 15 semantic differentiated by-polar scales. The major finding were : The factor structure of Clothing Silhouette Image were found to include 4 factor dimensions-Capability Evaluation, Function, Activity. It was clear that Silhouette Image were affected by Life Spaces. There were the differences of Image Evaluation related to Grouping of Line and Grouping of Body Emphasis. There were the differences of Life Space Evaluation related to Grouping of Line and Grouping of Body Emphasis. Therefore it is important to considerate Life Space for selecting Clothing Silhouette.

This study was conducted to identify the Colletotrichum species causing anthracnose disease of strawberry in Balgladesh and to evaluate in vitro activity of commercial fungicides it. Based on morphological and cultural characteristics, all 22 isolates were identified as Colletotrichum gloeosporioides. They developed white or glittery colonies with grey to dark grey reverse colony colors and they produced cylindrical conidia. The efficacy of five commercial fungicides, Bavistin DF, Dithane M-45, Sulcox 50 WP, Corzim 50 WP and Rovral 50 WP, were tested against the fungus. Bavistin inhibited radial growth completely and was followed in efficacy by Dithane M-45. In Bavistin DF treated media, the fungus did not produce conidia. The percent inhibition of radial growth of the fungus was increased with the increasing concentrations of fungicide.
