Electronic Commerce is rapidly expanding with the development of internet and will be very useful for the consumers in the future. However, we could not find many studies on consumers' attitudes and behaviors in the cybermarket. The purpose of this study is to analyze perceptions of college students in Seoul and Chunchon on Electronic Commerce. The main findings are as follows. First, they prefer surfing on the net with search engines like Simmamai or Yahoo to directly looking over the homepages of department stores and advertisement sites. Students in Chunchon, especially, tend to check out banners at E-mail sites. Second, most of the students get information about shopping mall sites and products from their friends, newspapers or magazines. And they want to have information (advertisements) classified by brand names of the products. Third, students in Seoul rely on brand names more than those in Chunchon do. Students in Chunchon, compared with those in Seoul, believe more kinds of products are available in the internet shopping mall. They complain, however, deficiencies of information about the products and high prices. They want the price information compared with those in traditional markets. Fourth, they feel very uncomfortable about informing their credit card numbers, and thus prefer payments with Electronic Money. And finally, they are not satisfied with return and exchange policies and after-sale services. They also complain that the products are not delivered safely when they are not home. They want the delivery-date indicated.

In this study, we considered the clustering analysis for stock return traded in the stock market. Most of financial time-series data, for instance, stock price and exchange rate have conditional heterogeneous variability depending on time, and, hence, are not properly applied to the autoregressive moving-average(ARMA) model with assumption of constant variance. Moreover, the variability is font and center for stock investors as well as academic researchers. So, this paper focuses on the generalized autoregressive conditional heteroscedastic(GARCH) model which is known as a solution for capturing the conditional variance(or volatility). We define the metrics for similarity of unconditional volatility and for homogeneity of model structure, and, then, evaluate the performances of the metrics. In real application, we do clustering analysis in terms of volatility and structure with stock return of the 11 Korean companies measured for the latest three years.

One of the main goals of providing open access is to vitalize the exchange of academic information by allowing access to the scholarly research outputs for everyone without the legal, financial, and technical barriers. We regard the use of the institutional repository as an open access enabler. In this study, we tried to make the factors, which enable the successful deployment of the institutional repository, explicit. We utilized literature review and case studies to generate the potential success factors for the institutional repository deployment. We verified the factors by having in-depth interviews with the subject matter experts. The resulting factors were organized as organizational, political, and technical ones. The organizational factors included the strong open access support by the organization heads. Under the policy factors, a number of issues such as selection of the core contents, minimum quality control, protection of the copyrights, forming supporting groups through active advertising, long-term preservation, incentive, and mandate, were included. The technical factors included easy submission, support for interoperability, and support for the publication activities.

This study examines the optimal fractionation method and conditions for the isolation of endoprotease- and exopeptidase-active fractions from crude extracts of cuttlefish hepatopancreas (HP) using four fractionation methods: ammonium sulfate fractionation (ASF), polyethylene glycol fractionation (PGF), ion exchange chromatography (IEC), and gel filtration chromatography (GFC). Total endoprotease activity highest in the fraction II (concentrate of fractions 34-42; 842.60 U) of GFC, followed by fraction III (40-60% ammonium sulfate fraction; 670.25 U) of ASF, fraction I (concentrate of fractions 8-12; 436.89 U) of IEC, and fraction II (10-20% polyethylene glycol; 307.31 U) of PGF. Total exopeptidase activity of these fractions was highest in fraction II (2,704.70 U) of GFC, fraction III (2,110.50 U) of ASF, fraction III (1,605.60 U) of PGF, and fraction II (concentrate of fractions 38-44; 1,196.22 U) of IEC. These results showed that fraction II of GFC had the highest activity toward both exopeptidase and endoprotease, with exopeptidase activity being 3.21 times higher than of endoprotease. These results suggest cuttlefish HP could be used as a potential source for the extraction of exopeptidase, an enzyme capable of catalyzing the cleavage of N- and C-terminal amino acids in polypeptides, Like endoprotease, the most efficient method for separating exopeptide-active fractions was GFC.

Among the causes of childhood behavioral problems - that is, physiological, psychological, and environmental factors -, the common element of non-organic psychological and environmental factors is influences from the parents. Roles of mother who does the biggest emotional exchange with the child after birth may have substantial association with the childhood behavioral problems. In this connection, the present explanatory study was conducted for the purpose of understanding the causal structural relationship in which mother's child caring behaviors affect child behavioral problems. The data collection period was July 2 - 7, 2001. The subject was 4th, 5th, 6th graders' mothers in 4 elementary schools located in Daejoen city and 299 surveys were used in the analysis. As for the tools used in this study to assess the mother's child caring Behavior Scale by Park, Seong-Yeon and Yi, Sook (1990) was used to measure the mother's behaviors. The child behavioral problems were measured with the Korean-Child Behavior Checklist (K-CBCL), standardized into the Korean version by O, Gyung-Ja, Yi, Hye-Ryon, Hong, Gang-Eui, and Ha, Eun-Hye. For the data processing, the frequency and the percentage were calculated, and the analyses of variance, correlation were carried out. The result of this study is summarized as follows: First, the examination of the effect of mother's general characteristics on the mother's caring behavior shows that significant differences are made by the active participation (p=0.020) in the occupation, affection(p=0.000), authority control(p=0.013), achievement(p=0.030), active participation(p=0.032) in the education level, consistency regulation(p=0.007) in the religion. Second, the examination of the effect of mother's caring behaviors on the child behavioral problems shows that significant differences are made by some child behavioral problems in the affection, achievement, consistency regulation, authority control, over protection caring behaviors. Third, as for the correlation between mother's child caring behavior and child behavioral problems, a significant correlation is revealed between the negative child caring behavior and child behavioral problems.

Writing a CAI program containing Chinese characters requires a common Chinese character code to share information for educational purposes. A Chinese character code setting needs to allow a mixed use of both vowel and stroke order, to represent Chinese characters in simplified Chinese as well as in Japanese version, and to have a conversion process for data exchange among different sets of Chinese codes. Waste in code area is expected when vowel order is used because heteronyms are recognized as different. However, using stroke order facilitates in data recovery preventing duplicate code generation, though it does not comply with the phonetic rule. We claim that the first and second level Chinese code area needs to be expanded as much as academic and industrial circles have demanded. Also, we assert that Unicode can be a temporary measure for an educational code system due to its interoperability, expandability, and expressivity of character sets.

This paper tried to understand the effects of alcohol-reducing program on drinkings behaviour of workers on works under 5 employees. For these, this paper understood a change of drinkings custom and degree of alcohol-reducing strategy practice by enforcement of alcohol reducing program over 7 times during 3 months Reaults from analyses are as follows 1) A health problems related to drinkings were a chronic fatigue and indigestion, 15.5% was over 5 items among items related to liver disease. 2) The subjector of investigation all was involved over 2 items among items that a drinking custom must be collecred. 3) The change of drinkings custom between before and after on enforcement of alcohol reducing program showed a effective difference. 4) For a degree of the alcohol-reducing strategy practice, "reducing drinkings days" was 82.9%. "bearing drinkings impulse" 70.7%, "exchanging drinkings custom" 56.1%, "avoiding drinkings friends" 51.2%, Yet, "avoiding drinking place" and "preparing leisure activity to exchange drinkings" showed a low practice ratio. 5) For correlation between drinkings drinkings behaviour and degree of alcohol-reducing strategy practice, the more drinkings times before program paticipatance the higher alcohol-reducing strategy practice, alcohol dependency and drinkings times, alcohol-reducing strategy and drinkings times, befere drinking custom had an effective negative corelation, after drinkings custom and alcohol-reducing strategy a strong effective positive corelation. 6) workers writing drinkings paper decreased drinkings times. Implications from results are as follows The alcohol-reducing program is necessary to works under 5 employees, and needs to he operated continously. Especially, in works under 5 emplyees, the alcohol-reducing programt needs to be operated by firm or government.

Research on recovering original images from captions has been widely done in a reusability point of view. In usual, dynamic images imported from foreign countries often have captions of foreign languages, so it is necessary to translate them into one's language. For the natural exchange of captions without loss of original images, recovering the images corresponding to captions is necessary. However, though recovering original images is very important, systematic analysis on the characteristics of captions has not been done yet. Therefore, in this paper, we first survey the classification methods of TV programs at academic worlds, broadcasting stations, and broadcasting organizations, and then analyses the frequency of captions, importance of caption contents, and necessity of recovering according to their types. Also, we analyze the characteristics of captions which are significantly recognized to be necessary to recover, and use them as recovering information.
