This study is aimed at investigating and developing the use and sizing system of the apparels listed in on-line and catalog shopping in Korea. This is a basic study for an apparel sizing system to be developed, which could be used to approach consumers more easily and provide improved fitness and accuracy in terms of size and style of apparels for fashion E-commerce. A survey was conducted among the consumers who are more than 18-years-old and purchased more than two times the apparels listed in on-line and catalog shopping of two selected catalog shopping enterprises, and its statistical results are analysed from 281 respondents' questionnaires. The results of the study are as follows: 1. According to the result of the survey on the use and sizing system of the apparels listed in. on-line and catalog shopping, the consumers who purchased once apparels continue doing so in the same manner. A catalog shopping is the most preferred form of shopping. The most dissatisfying part in purchasing apparels is a poor quality of 'texture', and the second biggest problem is about 'size'About 51.2 percent of the apparels were not worn or even returned, while the top reason for that is 'Inappropriate size' and 'color', and 'texture'comes next on the list. 2. According to the survey on the recognition-rate concerning common' body size, most respondents were aware of their height and weight, and So percent of respondents said that they were aware of their waist circumference. But, chest circumference and hip circumference were recognized only by 58.4 percent and 35.6 percent of respondents, respectively. 3. According to the survey on difference between men and women, the male consumers have less aware of hip circumference than the female counterparts. The females have much more dissatisfaction with apparel sizing system and show higher return-rate of purchased apparels than the males.

The dipole-dipol electrical resistivity survey was conducted to investigate the probable contamination of the Han river by leachate from the near-by Nanjido Landfill. The survey line of 3 km was set along the unpaved road toward the Han river. For the convenience of the field work, the survey line was divided into four segments. The complete two-dimensional resistivity section was constructed by connecting the inversion result of each segment. Gravity survey was also carried out along the profile parallel to the resistivity line. Near surface resistivity generally appeared to be of very low value in most part of the survey area and the boundary between the alluvium layer and underlying basement rocks is well discriminated on the resistivity section. These results agree well with those of the preceding Schlumberger depth sounding made at adjacent area by Lee and fun (1995). The variation of thickness of the alluvium layer delineated by gravity anomaly profile also correlates well with the result of the resistivity survey on the qualitative basis. The problem of contamination by leachate from the Nanjido Landfill, where various waste materials have been dumped without any proper treatment facilities, has been remains unsolved yet. Therefore, we present the most probable passages of leachate flow based on the survey results and have briefly discussed about measure for contamination control. Considering the thickness of alluvium and the possible existence of fractured zone, the middle point between 1st and 2nd landfill and the midst of 1st landfill are the most hazardous regions to make leachates flow into the Han river. Since large amounts of leachates are observed from the test wells located on the lines extending from the border between the 1st and 2nd landfill and the middle of the lst landfill, contamination protection barriers are strongly recommended near these regions.

This study aimed to present marketing communication strategy for lifestyle groups. Consumers' preference on advertisement media/information source, advertisement appeal types, and on-line media use were examined by lifestyle groups. This study was executed by web survey and off-line survey. A total of 141 data was obtained and data were analyzed by PASW 18.0. Results were as follows: First, 4 types of lifestyle groups were made up by holistic approach; 'price oriented', 'traditional symbolic', 'positive life', and 'open mind enjoyment'. 'Positive life type' preferred every type of ads media. 'Traditional symbolic type' liked magazine and 'price oriented type' and 'open mind enjoyment type' thought off-line store display more important. For ads appeal types, 'positive life type' preferred social oriented appeal type. Every group except 'price oriented type' preferred emotional appeal type and especially 'open mind enjoyment type' liked the most emotional ads appeal type.

This study investigated the characteristics of on-line auction users with addictive tendencies. A questionnaire survey was conducted on-line between September 9 and 14, 2005 and 1,608 adults who had experience in on-line auctions participated. As a result, 23.5 percent of the subjects in this study were shown to have addictive tendencies in their use of on-line auctions. The socio-demographic factor found was gender difference. That is, men were more likely to show addictive tendencies than women. The subjects who had addictive tendencies showed certain psychological characteristics such as lower self-esteem more symptoms of depression, and a higher sense of alienation compared to those without addictive tendencies. Finally, on-line auction users who had addictive tendencies were shown to visit on-line auction site more frequently and to stay logged on the auction site longer than non-addicts, reflecting that the frequent the use of on-line auction, the higher the possibility of addiction to on-line auction.

We present the statistical properties of a volume-limited sample of 7,429 nearby (z = 0.033-0.044) galaxies from the Sloan Digital Sky Survey Data Release 7. By performing a visual inspection, we classified our sample galaxies according to the Hubble sequence (Hubble 1926, 1936). Then we excluded apparently smaller and flatter galaxies from our database because morphology classification on them turned out to be difficult. Our results cover structural (e.g. concentration index, color, magnitude, stellar mass, etc.), spectroscopic (e.g. velocity dispersion, $H{\beta}$ absorption line, Fe absorption line, Mg absorption line, accretion rate, $H{\alpha}$ emission line, etc.), and environmental (e.g. density, etc.) properties of each morphology type based on morphology distribution. For this analysis, we used the recent re-measurements of spectral line strengths by Oh and collaborators (2011). Our statistics confirm the up-to-date understanding on galaxy populations, e.g., correlations between morphology and line strengths and in turn derived ages and so on.

In this paper, we propose a line composition based searching system which retrieves compositionally similar photo from the DB of the line-compositional photos. To develop the measure of compositional similarity, we carried out a survey to find which feature is discriminative for retrieving. Based on the results of the survey, we developed the measure of compositional similarity and it was applied the proposed searching system. We also show the results of the recall and the precision to evaluate the performance of the proposed system.

The study has been initiated on the background of rapidly changing environment, and from the perspectives that new ecological systems are continuously generated accordingly in various fields. Recently, ICT platform, which is the platform related to information communication, has drawn much attention, and many tools are being made that can design and implement documents in a specific on-line space by utilizing UI/UX authoring tools for on-line contents sharing platforms which are public platforms for industrial and educational uses. Following these trends, actual building environment for 'XElF', a newly developed on-line contents sharing platform, and actual design proposal for UI/UX authoring tools will be described according to the sequences of building the platform. Before this design proposal is actually utilized in the future, opinions have been collected from related persons through an actual survey. Efforts are being made to reduce problems, which can be generated in the future in the actual on-line contents education environment, through the results of the study so that the platform can be produced without errors. The final results for this matter are planned to be posted by papers in the future.

This study is an attempt to provide some answers to question about how characteristics and general recognition regarding internet use in Korea and Japan influence fostering and maintaining on-line social network in each of countries. Survey is used to compare Korean internet users and Japanese internet users in terms of characteristics of on-line social network, individual's propensity for internet use, including their recognition on internet. The study's main findings go as follows. First, Korean internet users tend to be more active in using internet than Japanese internet users do, thus having larger on-line social network and more intensive internet use than Japanese internet users do. However, there is a commonality that majority of internet users in both countries use internet to connect them to person with whom they have private relationship but they cannot meet frequently. Second, for Korean internet users, individual's propensity, characteristics, and recognition regarding internet use is not related to how to contact others. To the contrary, for Japanese internet users, how to contact others in on-line setting seems to vary according to whether or not they have relation-oriented internet use and how they recognize the availability of internet. Third, a commonality regarding the size of on-line social network is found between Korea and Japan that the total numbers of people enrolled as network increases if people use internet in order to get information. This confirms previous finding that relationship based on weak tie is instrumental in fostering on-line social relations and likely produces advantage in getting information. Finally, for Japanese internet users, the degree of risk recognized in on-line setting, that is the degree of interpersonal trust, appears to greatly influence overall relationship -building in on-line.
