In Korea's point of view the ASEAN is geographically located near to Korea's peninsula and can supply Korea with IT products safely, it is also a significant market that we can effectively export IT products. This study analyzes ASEAN as a. strategic market, by enlarging the IT export and import, Korea's IT market excessively leaning upon the United States and Japan's market, so ASEAN is the proper market to which we can drive multilateral trade of IT market and multikinded trade of goods. In order to enhance exports of various IT products, we have to retain a good reputation and to remove revolting factors. Also, the marketing of Korea's IT export against ASEAN have to reinforce and to activate the direct investment, plant exports, and loan credit. Therefore, this study reviews Korea's IT Industry analysis to ASEAN, and finally we suggest the way to solve the main problems.

This ethnographic case-study explores the interpretation and behavior in job considering among full-time housewives. The participants of this study are eleven middle class full-time housewives in their thirties and forties. In-depth interviews based on an unstructured Questionnaire were conducted for this study. Findings are as follows: Six full-time housewives tend to think their full-time housewife-lives more convenient, something unable to substitute and more profitable compared to the counter partner's lives. But they are classified into two groups according to the satisfaction for full-time housewife life. One group has found out more positive meaning in their life but the other group has not yet and they are doubtful about real life and other opportunity. In Contrast, other five full-time housewives tend to interpret employment as a more productive source to secure family resource for their children's education and repay the loan used to buy larger apartment. And the job is considered to confirm her own individuality and the feeling for the social entity as a competent social entity. But two of them who have never been employed do not try to get a job as a new identity alternative. And the various elements like household income, job experience, health, children's age and husband's attitude to his wife's employment etc. are defined to influence the interpretation and the job considering behavior among full-time housewives.

This study is on the forecasting performance analysis of range volatility estimators(Parkinson, Garman and Klass, and Rogers and Satchell) relative to historical one using two-scale realized volatility estimator as a benchmark. American sub-prime mortgage loan shock to Korean stock markets happened in sample period(January 2, 2006~March 10, 2008), so the structural change somewhere within this period can make a huge influence on the results. Therefore sample was divided into two sub-samples by May 30, 2007 according to Zivot and Andrews unit root test results. As expected, the second sub-sample was much more volatile than the first sub-sample. As a result of forecasting performance analysis, Rogers and Satchell volatility estimator showed the best forecasting performance in the full sample and relatively better forecasting performance than other estimators in sub-samples. Range volatility estimators showed better forecasting performance than historical volatility estimator during the period before the outbreak of structural change(the first sub-sample). On the contrary, the forecasting performance of range volatility estimators couldn't beat that of historical volatility estimator during the period after this event(the second sub-sample). The main culprit of this result seems to be the increment of range volatility caused by that of intraday volatility after structural change.

The purpose of this study was to analyze the factors negatively affecting college life, to investigate the perception gap between housing types, and to generate preliminary data for increasing residential satisfaction of students who live in temporary housing(e.g., dormitory or one-room). The utilized research methods included a questionnaire survey and an in-depth interview. The college students, especially from other regions, experienced more financial difficulties than others. They managed their tuition and living expense/allowance by parents supports and other sources(e.g., scholarship, arbeit, work in college, loan etc.). The reasons to choose dormitory, as temporary housing, were short distance to college and low costs. In case of one room, independent life was main reason to choose. Gender differences affected to the decision, moving away from present temporary housing. For example, male students preferred an independent life and a short commuting distance, while female students preferred an independent life and a safe life. Thus, considering the origin and gender differences of residents, dormitory planning needed to develop plans allowing independent life and to choose appropriate site for the purpose. In case of planning one room apartment, concerns for safety and landscape were more important than other factors.

In this study, collapse test of thin-walled structure is performed under axially quasi-static and impact load in collapse characteristic to develop the optimum structural member for a light-oriented automobile. Furthermore, the energy-absorbing capacity is observed according to the variety of configuration(circular, square), aspect ratio in aluminum specimen to obtain basic data for the improved member of vehicle. In both quasi-static and impact collapse test, Al circular specimens collapse, in general, with axisymmetric mode in case of thin thickness while collapse with non-axisynmetric mode according to the thickness increase. For Al rectangular specimens, they collapse with axisymmetric mode in case of thin thickness, with mixed collapse mode according to the increase of thickness. In terms of initial max. load, Al square specimen turns out the best member among specimens, and then Al square, circular and circular with large scaling ratio, respectively. In case of quasi-static compression test, the absorbed energy per unit volume and mass shows higher in Al circular specimen, and then Al square, circular with large scaling ratio, respectively, according to shape ratio the absorbed energy per unit volume and mass in case of max. impact compression load is higher than that of static load. But the absorbed energy per unit volume and mass shows that Al circular specimen is the best member. Especially, unlike max. compression loan, the absorbed energy per unit volume and mass in impact test turns out the low value.

How does social interaction among investors affect decision-making in the online social lending platform? And what is the reason? In this study, in order to obtain the answer, we carried out case study research of Moneyauction and Popfunding, which are domestic online social lending platforms. We conducted interviews with managements of both social lending platforms and investors and analyzed statistical data including investment records, social interaction history between investors and lenders from both platforms. In addition, researchers performed direct participation and observation through the platforms as real investment members. As a result, we revealed that social interaction among investors has a material impact on the investment decision-making. Also we found that investors build trust by socially interacting with each other and this trust building leads to the investment decision making. Our findings confirm that social lending investors's decision-making process comply with the social embeddedness theory and imply that loan applicants must do their best efforts to display sincerity and truthfulness through their posting.

This study analyzes the locution of television home shopping show hosts for apparel products with a focus on the selling points and vocabulary use. A qualitative content analysis was conducted for 15 recorded home shopping shows selling women's overcoats and jackets. The results are as follows. First, 8 dimensions of selling points were revealed: Promotions, brand popularities, the experiences of shopping hosts, fashion trend information, conformity motivation and suggestion, intangible attributes, tangible attributes, and compared/leading differences. The most frequent selling point was tangible attributes. Following this were, promotions, conformity motivation and suggestion, compared/leading differences, intangible attributes, brand popularity, the experiences of the shopping hosts, and fashion trend information in order. The selling points were almost proper to decrease the perceived risks of home shopping consumers. Second, shopping hosts frequently used the clothing terms without any expatiations and used loan words (foreign language terms) instead of the direct Korean translations. In the conclusion, the development of a marketing strategy focusing on shopping host management is suggested.

Recently, support vector machines (SVMs) are being recognized as competitive tools as compared with other data mining techniques for solving pattern recognition or classification decision problems. Furthermore, many researches, in particular, have proved it more powerful than traditional artificial neural networks (ANNs)(Amendolia et al., 2003; Huang et al., 2004, Huang et al., 2005; Tay and Cao, 2001; Min and Lee, 2005; Shin et al, 2005; Kim, 2003). The classification decision, such as a binary or multi-class decision problem, used by any classifier, i.e. data mining techniques is cost-sensitive. Therefore, it is necessary to convert the output of the classifier into well-calibrated posterior probabilities. However, SVMs basically do not provide such probabilities. So it required to use any method to create probabilities (Platt, 1999; Drish, 2001). This study applies a method to estimate the probability of outputs of SVM to bankruptcy prediction and then suggests credit scoring methods using the estimated probability for bank's loan decision making.

In Korea, rural village improvement has mainly been led by goverment investment. This approach, however, has its own limit since there are so many village to be improved while the budgetary sources are restricted, As an alternative, inducement of private investments to these area is considered in order to promote rural village improvement. The possibility of inducing private investments to the rural village improvement depends on the location of the village. The possibility may be highest in the sub-urban area since expected benefits from land development is usually high. One desirable approach to induce private investment to these area is the cooperative development system. Residents, private investors and governments plays its own role, independently and cooperatively, But benifits from the investment to improve rural village in general plain area are so low that it is difficult to induce the private investments to these area. In that case, indirect development system will be a proper strategy which maintaining government-led development method as usual, expanding the participation of private developers such as the construction companies. In general, rate of returns from investment to the rural sectors is lower than that to the other sectors, therefore financial support such as the long- term, low loan rate and a partial value-added tax exemption should be given to the investors to the rural village improvement projects.
