This study reviews and modifies general IS success models to find success factors of WIS(Web-based Information Systems) and to confirm the relationship between WIS success and user's satisfaction of web use. A WISSM(Web-based Information Success Model extended to include EQ(E-Quality) is developed to anticipate user's intention to use Web-based Agricultural Information System and fit into the survey data from 252 WIS users of RDA(Rural Development Administration). PLS is applied to estimate a structural model based on EQ-WISSM to test hypotheses including 1) users reach a high level of intention to use Web-based Information Systems when they feel a high level of interactivity among an 'E-Quality', 'Decision Making Support Satisfaction' and 'Task Support Satisfaction', and E-Quality boosts intention to use Web-based Information Systems. The results show high path coefficients and $R^2$ values and find followings; First, the EQ-WISSM explains the user's intention to use WAIS quite well. Second, E-Quality can be used well in web-based IS environment to predict IS Success. Finally, this research finds the importance of 'Task Support Satisfaction' as a mediator between 'Decision Making Support Satisfaction', 'E-Quality' and 'Intention to Use'.

The goal of this study is to establish an integrated watershed hydrologic model for the whole Nakdong River basin whose area is an approximately 24,000 km2. Including a number of watershed elements such as rainfall, runoff, water use, and so on, the proposed model is based on SWAT model, and is used to improve the flow duration curve estimation of ungauged watersheds for Korean Total Maximum Daily Load (TMDL). The model is also used to recognize quantitatively the river flow variation due to water use elements and large dam effluents in the whole watershed. The established combined watershed hydrologic model, SWAT-Nakdong, is used to evaluate the quantified influences of artificial water balance elements, such as a dam and water use in the watershed. We apply two water balance scenarios in this study: the dam scenario considering effluent conditions of 4 large multi-purpose dams, Andong dam, Imha dam, Namgang dam, and Habcheon dam, and the water use scenario considering a water use for stream line and the effluent from a treatment plant. The two scenarios are used to investigate the impacts on TMDL design flow and flow duration of particular locations in Nakdong River main stream. The results from this study will provide the basic guideline for the natural flow restoration in Nakdong River.

The purpose of this study is to help operate and manage the new food period system by investigating consumer perception of sell-by-date and use-by-date, and change of purchasing and consumption period by food period label. Although they have opinions that fit the purpose of introducing the system, such as the need to introduce a use by date, extending the food intake period, and reducing food waste, they still lack an accurate understanding of the system, so education or publicity is needed. In addition, no matter what form of use by date is introduced, products with food expiration date are still likely to be returned or discarded. Therefore, it is desirable to adjust the setting criteria or safety factor for each deadline rather than changing the food period labeling method. In order to reduce consumer confusion and food waste, it is judged that the parallel marking of the sell by date and use by date is appropriate.

Objective: There is a growing interest in the safe use of medications in pregnant and breastfeeding women. Therefore, the purpose of this study is to find ways to improve education about safe medication use by investigating the status of medication use of pregnant and breastfeeding women, and by evaluating their knowledge, attitudes, and practices toward safe medication use. Methods: In this study, a self-report questionnaire was conducted on pregnant or breastfeeding women in Seoul and Gyeonggi Province. The questionnaire consisted of the following four sections; 1) sociodemographic characteristics of participants, 2) experience of medication use, 3) experience of being educated on safe medication use, and 4) knowledge, attitudes, and practices about medication use during pregnancy/breastfeeding. Results: A total of 203 participants were included in the analysis. Of these, 38.4% reported to take prescription medications during pregnancy and breastfeeding. Regarding education on safe medication use, nearly 90% of the participants answered that they were not educated or were unsure whether they had it. In the knowledge-attitude-practice evaluation on safe medication use, the knowledge level was the highest (mean, 4.45), followed by the attitude level (mean, 3.58) and the practice level (mean, 3.33). The preferred education method of the participants was online education using a computer or mobile phone application, etc. Conclusions: This study suggests that there is a need for systematic and effective education that can link knowledge of safe medication use with attitudes and practices in pregnant and breastfeeding women.

The purpose of this study is to measure the resource use of the elderly in long-term care services and to examine the effects of patient and facility characteristics on their use of resources. The data were collected from 510 old people over sixty years of age, residing in five long-term care hospitals and two skilled nursing homes during the period between December 1, 2000 and February 28, 2001. For a full sample, when the first level of RUG(Resource Use Group)-III categories were employed as the proxy of patient severity, facility characteristics, such as location, size and ownership, have large effects on the resource use measured by service intensity, whereas patient characteristics such as severity have little or no effect. The resource use is significantly high if the facility: (1) is located in rural areas (gun): (2) has mare than 200 beds; (3) is a long-term care hospital; (4) is private; and (5) has a low percentage of medical aid patients. The analysis of the resource use in each RUG-III categories, for which ADL(Ability of Daily Living) were employed as the prosy of patient severity, shows a similar result. The loose relationship between the needs of residents and the resource use seems to be closely associated with the ineffective reimbursement system for providers. The current reimbursement system has no provision for quality improvement and reimburses facilities simply according to their types: fee-for-service for long-term care hospitals, and monthly-flat-rate or full-coverage-national-aid for skilled nursing facilities. It will be necessary to develop a more reasonable reimbursement system that takes patient's severity into account and gives incentives for long-term care providers to offer cost-effective services.

대부분의 건축규제는 건축물의 용도에 따라 적용되기 때문에 건축물의 용도분류체계는 명확하고 일관성이 있어야 한다. 하지만 현재 건축물 용도분류는 건축법 이외에도 각 개별 법령에서 규정하고 있어 법령적용에 많은 혼선을 야기하고 있다. 특히, 최근 건축물의 초고층화 대형화 복합화 등으로 인해 건축물 화재 및 피난안전성능 확보를 위한 건축규제가 지속적으로 증가하고 있는데, 우선적으로 건축법과 소방시설 설치유지 및 안전관리에 관한 법률간 건축물 용도분류체계의 연계성 확보가 매우 시급한 실정이다. 이에 본 연구에서는 건축법과 소방시설설치유지 및 안전관리에 관한 법률에서 규정하고 있는 건축물의 용도분류 및 용도별 건축물의 종류를 상호 비교하여 상이점을 도출하고 이를 개선할 수 있는 방안을 제시하였다.

Purpose: Internet is one of the essential tools in South Korean adolescent life. Recently, researchers suggest that Internet use is positively associated with teens' mental health problems such as depression and suicide. Thus, this study explored a relationship between Internet use and suicide ideation among South Korean adolescents. Methods:　Secondary data, the three-wave Korean Youth Panel Survey, were analyzed. First, in terms of the levels of Internet use and suicidal ideation, t-test was used for examining a gender difference, and Analysis of Variance were used for examining differences across three points in time(waves 2 - 4). Second, logistic analysis was performed to examine the significant association between Internet use and suicide ideation after controlling for the other factors' effects. In this analysis, Fixed Effect Regression Method(FERM) was incorporated as well. FERM was useful in adjusting for the effects of time-invariant factors even without measuring them. As a result, it was possible to obtain more accurate findings. Results: Adolescent depression was an important factor influencing the association between Internet use and suicide ideation. After controlling for the effect of depression, the relationship between Internet use and suicide ideation was no longer statistically significant. Conclusion:　As a proxy to identify teens who are obsessed with suicide ideation, levels of Internet use do not seem useful. Instead, it is necessary to examine teens' access to websites related to suicide.
