If we followed to be based on the result of survey for researching on the actual condition about e-Learning of the MOE(2004), the critical problem has been suggested managing the quality of teaching and learning materials(37.68%(1775/4717)). If we also reviewed the research of the KICE(2002), the superior material's rate of 70,000 teaching and learning materials of the web site, the educational organization, and teachers was 8.7%. There was some suggestions about the quality problem of the teaching and learning material, but there wasn't the alternative policy: there wasn't the systemic program for managing the message quality of teaching and learning materials. The purpose of this study was to develop the alternative system for managing the message quality of teaching and learning materials. The alternative system of this study's result will be the basic to build the system for managing the message quality of teaching and learning materials. I expect that my system will be the useful tool for managing the message quality of teaching and learning materials.

Damage caused by private information breach causes serious problems and huge social losses. In order to make a better policy that prevents society from suffering from the damage, we have to know about the actual size of damage. So it is needed to develop a quantitative model of private information breach that helps catching the more accurate size of damage. In our study, we suggest a method which calculate not only the costs of damage from firms' perspective but also those from individual and social perspectives. In this process, we refer to methods adopted by JNSA(Japan Network Security Association) and Ponemon Research Institue and modify it with considering our current situation. Also we try to make a new model by using new methods(web traffic analysis, survey, indirect comparison, etc.) and verify it with theories and methods from econometrics, cost accounting and theory of producer.

In this paper, we draw upon Task-Technology Fit theory to investigate the fit attributes which impacted on customer preference over three virtual shopping channels which included TV home shopping, Internet shopping, and broadband applications, i.e. IPTV. The fit attributes also reflected the product category contingency, which is classified based on the degree of quality assessing difficulty on the web, such as quasi-commodity, look and feel goods, and look and feel with variable quality goods. Using the collected survey data, we employed stepwise regression analysis to validate the fit attributes in the context of performing virtual shopping task via those three distinctive media technologies. Furthermore, through ANOVA test with Duncan statistics, we reported comparative intensity of the valid fit attributes across the product categories and distinct media technologies. The results validated four critical fit attributes and significant distinctions among product categories and three virtual shopping channels. The findings provide practical insights in distribution channel design exploiting digital convergence technologies.

Objectives: This study was performed to examine the relationship between health behaviors, living environment, and asthma in adolescents in Korea. Methods: Information on adolescents' characteristics, including demographic factors, health behaviors, and doctor's diagnosis of asthma was obtained from the Korean Youth Risk Behavior Web-based Survey (2015). In total, 68,043 middle and high school students participated. Environmental characteristics, including city park area and outdoor PM₁₀ concentrations in 2015 were obtained from the Korean Statistical Information Service. The adolescents' and environmental characteristics were merged by local information. Multiple logistic regression models were used to investigate the risk factors affecting asthma in adolescents. Results: The prevalence of asthma in adolescents in 2015 was 8.8%. In the multiple logistic regression analysis, adolescents who were male, attended middle school, suffered obesity, experienced tobacco smoking, had physical activity levels of 2 to 4 days, had higher stress levels, and lived in areas with outdoor PM₁₀ concentrations more than 47 ㎍/㎥ were more likely to have asthma, while adolescents who had middle levels of family economic status were less likely to do so. Conclusions: The fact that PM₁₀ concentration can affect asthma is an important point in this study. Risk factors identified in this study could be used as basic data for the prevention and management of asthma in Korea.

Since the cohousing idea, originated in Northern Europe, was introduced in the U.S. by architects Kathryn McCamant and Charles Durrett in the early 1980s, there are recently the largest number of cohousing communities and rapidly expanded in the U.S. So, it is necessary to appreciate the cohousing communities developed in U.S. In this study, we investigated the physical characteristics of cohousing and the methods of its residents' participation by means of a case study on cohousing communities in U.S. and suggested the future direction of the cohousing community. Also, this work could be exploited when the cohousing is introduced to Korea. At first, the general status and characteristics of U.S cohousing was explored using diverse sources such as literature, paper and Web site. And then, the direct visit survey was used to obtain the more exact and specific data about physical aspects and residents' participation in each community. We found that cohousing communities were mostly located in the urban and Rural area, which was founded in the 1990s, and new communities continue to be created in the U.S. Typically, the number of households is from 20 to 30 in one community. The land is generally owned by the community itself and its size is within 10 acres. Communities usually serve optional group meals in the common house at least two or five times a week. Each member's income is separated and the community members should take care of their common properties. The leader of community does not exist and most communities don't have the organization of community members. All cohousing communities use consensus as the basis for group decision-making.

Objectives: This study identified how personal characteristics, family environment, governmental policy for the prevention and cessation of smoking might influence on adolescent smoking. Methods: This study used data from the 2006 Korea Youth Risk Behavior Web-based Survey of 71,404 middle school and high school students, giving a response rate of 90.9%. We selected 61,508 adolescents subjects of the final analysis without missing data on independent variables and dependent variables which are used in this study. This study used $\chi^2$ tests and logistic regression models. Variables were added to the regression model in three groups using a hierarchical approach.Results: Adolescents were significantly more likely to become current smokers if they were boys, were in a higher grade, and had lower academic achievement. Adolescents experiencing stress and depression were associated with increased risk of current smoking. Adolescents with single parents or students of non-living with parents comparing with students of living with parents showed the high possibility of smoking. Lower father's education was associated with increased likelihood of current smoking. Adolescents who were exposed to smoking at home were more likely to smoke. Adolescents without contacting with the antismoking media campaign was associated with increased likelihood of current smoking. Conclusion: Promoting antismoking media campaigns targeted at adolescent is required, and the smoking prevention education which are proper for subjects are required. Proper plans which could decrease the exposure of secondhand smoking should be established.

As modern society leads to distinguished, sensuous, and diversity styles, a woman who enjoys putting on Garu makeup appeared on a popular TV talk show in winter 2010, which aroused public interest in the method of Garu makeup. However, as interest in Garu makeup and individuals who put on Garu makeup spread, some began to consider Garu makeup as the imitation of indiscreet Japanese culture or a vulgar culture. Thus the purposes of this study is to understand the characteristics of Garu makeup and its forms of expression by considering its type, origin and style. In turn, this study will provide basic data for the makeup trend and act as an aid to improve the image of Garu makeup through investigating its image and preference. To accomplish this purpose, this study reviewed relevant literatures and web resources, conducted a survey of students who study beauty art at two-year junior colleges in Seoul, and analyzed 195 answers by using SPSS 18.0. The results are as follows: It was proved that in the preliminary inspection of comprehension, 98.3% of college students majoring in beauty art had known Garu makeup, 53% understood somewhat the characteristic and concept of Garu makeup, 36.8% gave preference to Garu makeup. It was proved that in the investigation by the image of Garu makeup, as over 70% of students thought that Ogaru and Yamamba makeup were detestable, but other Garus were lovely and sexy, students perceived as a diversity of images by their own preferences and tastes, and 73% of respondents selected Onegaru as Garu makeup that they gave preference to and wanted to put on. The result of this study represents that mass consumers in the existing culture, who are college students majoring in beauty art and selected as a sample group in this study, reflect the stream of culture and trend, but also demassification, mass customization by their areas of interests and preferences and connective massification of individuals with similar interests.

The A low-cost carriers(LCC)' website represents their public face to the world. Futhermore, distribution through their own websites is generally regarded as the being most cost effective for airlines The Internet website has become an effective marketing vehicle for low-cost carriers(LCC). The objective of this study was to examine theoretical relationship of website quality, e-satisfaction, e-trust, and e-loyalty to the low-cost carriers' website. The study sample included respondents who had visited any LCC websites in the last 12 months. Data were collected by conducting a web-based survey to maintain respondents' anonymity and overcome time and place constraints. From the 334 usable data obtained, hypotheses are tested using structural equation modeling. The results indicate that website quality, e-satisfaction, and e-trust are antecedents of e-loyalty in loyalty relationships between passengers and low-cost carriers' websites. Website quality positively influences e-satisfaction, e-trust while e-satisfaction. However, contrary to our expectation, e-satisfaction has a negative effect on e-trust. Managerial implications are provided following presentation of the findings.
