The objective of this study was to predict land use change based on the land use change scenarios for the Hwangguji river watershed, South Korea. The land use change scenario was derived from the representative concentration pathways (RCP) 4.5 and 8.5 scenarios. The CLUE (conversion of land use and its effects) model was used to simulate the land use change. The CLUE is the modeling framework to simulate land use change considering empirically quantified relations between land use types and socioeconomic and biophysical driving factors through dynamical modeling. The Hwangguji river watershed, South Korea was selected as study area. Future land use changes in 2040, 2070, and 2100 were analyzed relative to baseline (2010) under the RCP4.5 and 8.5 scenarios. Binary logistic regressions were carried out to identify the relation between land uses and its driving factors. CN (Curve number) and impervious area based on the RCP4.5 and 8.5 scenarios were calculated and analyzed using the results of future land use changes. The land use change simulation of the RCP4.5 scenario resulted that the area of urban was forecast to increase by 12% and the area of forest was estimated to decrease by 16% between 2010 and 2100. The land use change simulation of the RCP8.5 scenario resulted that the area of urban was forecast to increase by 16% and the area of forest was estimated to decrease by 18% between 2010 and 2100. The values of Kappa and multiple resolution procedure were calculated as 0.61 and 74.03%. CN (III) and impervious area were increased by 0-1 and 0-8% from 2010 to 2100, respectively. The study findings may provide a useful tool for estimating the future land use change, which is an important factor for the future extreme flood.

This study was conducted to investigate the present situation and problems related to the use of nursing diagnosis in practice. The data were obtained from 332 subjects (27 director of nursing service, 302 staff nurses) who worked in university hospitals in Korea from July through August 1988 using a mailed questionnaire. Data were analyzed by frequency, X$^2$ test and t-test. The findings were as follows ; 1, Clinical use of nursing diagnosis by directors of nursing service and staff nurses. 1) The majority of the nursing departments (88.9%) conducted group education on nursing diagnosis during the last 5 years and 81.5% of them kept a record format for nursing diagnosis : 88.9% of them had had prior experience with the nursing diagnosis. 2) Most of nurses (97.0%) had received education on nursing diagnosis. 2. Factors related to the clinical use of nursing diagnosis in nursing service departments and by staff nurses. 1) The one factor related to the use of nursing diagnosis in the nursing service department was the existence of a record. 2) Factors related to the use of nursing diagnosis by the staff nurses were the organization style of the nursing service department, group education during the last 5 years, existence of a record, the attitude of the director of nursing service, and prior experience of the use of the nursing diagnosis as characteristics of nursing service department and educational experience of nursing diagnosis as a character of nurse. 3. Problems with the use of nursing diagnosis. 1) The primary problem was the lack of time and personnel (mean : 3.757) ; the second problem was the lack of knowledge and will to use nursing diagnosis in practice by the staff nurses(mean : 3.546). 2) There was no significant difference in problems expressed by the director of nursing services and the nurses. The majority of nurses who worked in the university hospitals expressed interest in and concern about the use of nursing diagnosis. Most of the nurses had had education about on nursing diagnosis but use in practice was limited. The primary problem was lack of time and manpower. Strategies for improving use of the nursing diagnosis in practice : 1) Strengthening the education about nursing diagnosis and a holistic approach to understanding human beings. 2) Develop protocols for the use of nursing diagnosis. 3) Eliminate the language barrier regarding nursing diagnosis by translation into in Korean. 4) Decentralization of the nursing service to promote accountability by individual nurses for use of nursing diagnosis.

In the past, the main function of land use categorization was merely used for basic data for taxation purpose, but recently land use categorization is used as important reference data in various ways, including administrative affairs, national land plan, land development, city maintenance as well as private transactions of land, in addition to the provision for assessment data. In the future, it can be expected to broaden its own functions. For expansion of the function of land use, we need to reconsider categories of land use from a perspective of individual laws and regulations actually regulating land use from a perspective of demand. In order to resolve any discrepancy between actual land use and land use on official books, the ultimate method of resolution is to study the current state of actual use of land and reflect them on official books, but it is also necessary to prevent any confusion of national people by unifying various categories of land adopted by the regulatory acts related to land. In addition, if the same administrative regulations are applied to different land use under the current laws, it is necessary to include them in the land of the same category. This study proposes to establish a new category for securing systematic consistency of the current categories of land use under the integrated cadastral act with other land laws and regulations.

With the development of information technology (IT), various information systems (IS) such as Web-based systems and mobile systems have appeared utilizing different technologies. However, recent studies on IS use and user satisfaction rarely account for technological differences among IS and environmental characteristics where IS are intended to be used. The purpose of this research is to investigate the determinants of the use of Web-based ticketing systems for cultural activities and to empirically validate their relationships. Environmental psychology suggests that human beings respond to external stimuli from environments with their emotions, and their emotional states influence human actions, e.g., IS use in this research. Applying environmental psychology to the use of Web-based systems in the culture and entertainment industry, we propose that web site characteristics first influence a user's internal state of mind (i.e., flow) and then the flow state influences the IS use. Studies related to the state of flow collectively affirm the key role played by the flow construct in shaping individual attitudes and behaviors toward IS. Users' flow states are captured by their shopping enjoyment, perceived behavioral control, and the level of concentration on the IS use. Referring to social presence theory, we have included such web site characteristics as content quality, context of web site, and community quality. In our research model, a second order construct is utilized to represent web site quality, because flow theory suggests that holistic experiences with web-based systems (rather than individual characteristics of the web site) are important in explaining the IS use. Further, we have included trust as another important factor influencing the IS use since business transactions on the web encompass higher uncertainty comparing to offline transactions. In order to test our hypotheses, we have conducted an online survey which results in 1,141 valid responses in the final sample. The data were collected from respondents who have experiences in Internet ticketing systems. Although it was a convenient sample, the sample represents a wide variety of user demographics. Validity and reliability of the research instrument were tested and research hypotheses were examined using PLS Graph 3.0. The results indicate that web site characteristics significantly influence the level of user concentration, user's enjoyment in shopping, and perceived behavioral control. Further, the use of Internet ticketing systems is influenced by users' flow states and trust in the web channel. User satisfaction is turned out to be affected by the use of Internet ticketing systems. Unlike extant research on the relationship between web site characteristics and its use, our study has found that, in the culture and entertainment industry, the impact of web site characteristics on IS use is mediated by a user's flow state. This finding has a practical implication that web site design should include as many features that enhance shopping enjoyment and concentration. Other practical implications of these findings and future research implications are also discussed.

Due to the recent development of SNS(Social Network Service) which is represented by Twitter and Facebook, social commerce market which combines on-line shopping mall and SNS is expanding. With increasing speed of its market, this study is to focus on detecting the crucial variables promoting the use intention, which results in the sustainable competitive advantage in social commerce market. This research empirically analyzed the use intention of social commerce. Also, this study explores the moderating effects of gender in explaining intention to use social commerce. A technology acceptance model is applied for pinpointing the antecedents of intention to use social commerce and for revealing cross-gender differences. The results from a survey of 452 participants reveal that the effects of perceived risk, perceived usefulness, ease for use and subjective norm on intentions to use social commerce differ across gender. Findings imply that the risk-free quality and portrayal of in-group or out-group situations of social commerce need to be communicated to female consumers, along with the social norms of using social commerce. When targeting male consumers, the technological features illustrating the usefulness of social commerce should be focused. This study will provide diverse implications companies providing social commerce services.

In order to cope with the demands of the rapidly changing society, advanced countries enrolled in OECD have been establishing corresponding directions as integrating their fields in economy, society, and education as one system. To be a part of the international changes, Korea has presented "Mixed-Use of schools and community facilities." "Mixed-Use of schools and community facilities" enables schools to expand necessary facilities, which were not secured due to insufficient budget, through community funding. Communities could not secure enough convenient facilities because they did not have enough sites for the facilities; however, school sites have made the communities possible to have facilities. As a result, the demand for "Mixed-Use of schools and community facilities" has increased. Therefore, this study redefines the concept of the Mixed-Use of School Facilities in the perspective of the main users, researches the current state of the Mixed-Use of School Facilities through case studies in Korea, and intends to research preferences of the synthesis through surveys. In addition, the study proposes the proper size and the standard of the facilities that are possible to synthesize them with schools. In the future, in running this Mixed-Use of School Facilities business, the data from this study can be utilized.

This study examined the childcare use pattern of the working mothers with preschool children and the factors affecting their use of multiple childcare. The 7th wave data of "Korea Welfare Panel Study" were analyzed for this study. The working mothers with preschool children were selected from the data set and a total of 292 working mothers were included in the analysis. More than 70% of the working mothers were using only one kind of childcare, mostly childcare center and kindergarten and 22.5% of the mothers were using more than two of childcare arrangements. Child factors, maternal factors, household factors, and economic factors were included in the hierarchical logistic regression model in the presented order to predict the use of multiple childcare. The results showed that the child's age and maternal education were positively related to the use of multiple childcare, while whether both parents live with the child, number of children within household, and the poverty status were negatively related to the use of it. Based on these results, we can confer that the main motive for multiple childcare use is to provide various experiences for their children.

The purpose of this study is two-fold: first, to examine the current status of e-dictionary use in Korea and the attitude toward its use by Korean college students; second, to investigate to what degree e-dictionaries may be useful and effective tools in helping to improve learners' overall English skills. The subjects were 84 college students and they were divided into two groups: the experiment group and the control group. The instrument employed was the Preliminary Student Usage Questionnaire, which was developed by the researcher, together with the questionnaire survey developed by Koyama and Takeuchi (2004), which was modified for the study. The findings from this research are as follows: First, a special instruction session on how to use e-dictionaries made a statistically significant difference among users of the dictionaries. Those subjects who had received the instruction displayed a more positive attitude toward the use of e-dictionaries. Second, the experiment group showed a more favorable attitude toward the use of e-dictionaries. On the basis of the above results, the researcher suggests that proper guidance on the use of e-dictionaries and their benefits should have a positive influence on users. The findings from the current research will shed light on the current status of electronic dictionary use among Korean college students.

Purpose: This exploratory study was to identify the use of complementary and alternative medicine(CAM) in women with breast cancer and to analyze which factor influence CAM use. Methods: 114 patients with breast cancer were identified and approached. The instrument used to gather data were the common types, main reasons and effects as well as stress, mood states and fatigue. Results: 42.7% of all participants reported the use of CAM. The most common types of CAM used were Phellinus linteus, elm tree, and vitamin C. The main reasons for CAM use were to boost the immune system and to prevent recurrence. Prayer, massage, Shitake mushroom, and Ganoderma lucidum were, identified as being more effective than others. 93.6% of the respondents informed their physicians of their use of CAM. Logistic regression analysis determined that stress, mood states, and duration after diagnosis were factors significantly associated with CAM use. Conclusion: CAM use is increasing among patients with breast cancer. Health care professionals are in the main position to identify what treatments patients are using and implement CAM therapies that can be helpful to relieve patient symptoms related to treatment and psychological distress.
