The Purpose of this study is the applicaion of social network analysis for expanding the use of spatial data in local government. Spatial data generated from UIS projects play very important roles as a means of supporting decision making and solving complicated urban problems, but the utilization of the spatial data has not reach the expected level, considering to the huge amount of investment. Accordingly, there should be efforts in efficient management of spatial data, establishment of a sharing system, and expanded utilization of spatial data. Social network analysis applied to this research is a theory that explains the behaviors and patterns of units forming the system and measures distances between nodes, strength, etc. based on relations among nodes forming the network and the structural characteristics of the network. According to the results of surveying civil servants who were using spatial data on Busan Metropolitan City, obstacles to the sharing of spatial data were mostly non technical factors related to data users' attitude and their relations with circumstances. In order to expand the use of spatial data, this study performed social network analysis that applied the theory of planned behavior and examined the flow of spatial data, and by doing so, we analyzed related personnel's perception, identified obstacles to data sharing, and suggested a framework for promoting the expanded utilization of spatial data.

This main purpose of this study was to assess the effects of two different types of ethics education on the moral judgement of clinical nurses. One type was free discussions among nurses with given specific moral issues and the other type was discussions guided by experts on specific moral issues. The study employed a quasi-experimental, nonequivalent pre test-post test design using two different control groups. The conceptual framework of the study was derived from the Kohlberg′s Moral Development Theory (1969) and the Greipp′s Ethical Decision-Making Model (1992). The data was collected during the period of October 14 through December 15, 1998. Sample consists of 32 nurses working in the ICU who met research criteria. 16 nurses were assigned to the free discussion group and 16 nurses to the group for the guided discussion with experts group. For the pre-test, the DIT which was developed by Rest (1984) and JAND by Ketefian (1998) were used with some modification by the author. After the education, only JAND was used to assess the changes in moral judgement. The collected data was analysed using SPSS PC program. The findings are as follows: 1. There was no significant difference between two groups in their general characteristics. Only difference which was statistically significant between two groups was that realistic score on Case 3/Medical Research and Autopsy was higher in the free discussion group. 2. Hypothesis 1: "There will be a difference on the moral judgement of nurses before and after they receive an ethics education". This hypothesis was supported partially. Those who had low scores on moral judgement before the education tended to have higher scores after the education on the same issues. And, after the education, the nurses tend to give lower scores on the dilemmas they had experienced frequently at work; while giving higher scores on those dilemmas they had no prior experience. 3. Hypothesis 2: "The effect of education may differ depended upon the moral development index [P(%)] score of nurses". The effect of education was different depend on moral development level. The group who′s P(%) scores was low at the pretest has higher scores in realistic moral judgement after the education, while the groups with middle or high P(%) scores went down after the education. These changes were statistically significant in some cases, thus, the Hypothesis 2 was partially supported 4. Hypothesis 3: "The method of ethics education will have different effects on the moral judgement of nurses". Even though several nurses attended the guided discussion stated that the education program broadend their perspectives the difference between two groups was not significant and this hypothesis was not supported. In conclusion, both types of ethics education had helped the nurses to acquire the skills to deal some nursing dilemmas. The effects of ethics education may differ according to the moral development index - P(%) score. However, because of some of the limitations of this study, mainly small sample size, short term education, unable to control other variables which may affect moral judgement of nurses, further research is warranted.er research is warranted.

The agency relationship between managers and shareholders has the potential to influence decision-making in the firm which in turn potentially impacts on firm characteristics such as value and leverage. Using an agency framework, we examine the relation between ownership structure and capital structure during post-IMF period. We used the balanced panel data for 378 korean listed companies during the 1999-2005. The panel data sets consist of time-series observation on each of 378 cross-sectional units. The results indicate a non-linear U-shaped relation between the level of managerial share ownership and leverage with the relation reaching a minimum at 58.48 per cent of management share ownership. As managerial share ownership increase from a low level, managers have incentive to reduce the debt level for decreasing the financial risk, resulting in a lower lever of debt. However, when corporate managers hold a significant proportion of a firm's shares, managers have incentive to increase the debt level for leverage effects, resulting in a higher lever of debt.

DAS(Driver Assistance Systems) support the driver's decision making to increase safety and comfort by issuing the naming signals or even exert the active control in case of dangerous conditions. Most previous research and products intend to offer only a single warning service like the lane departure warning, collision warning, lane change assistance, etc. Although these functions elevate the driving safety and convenience to a certain degree, New type of DAS will be developed to integrate all the important functions with an efficient HMI (Human-Machine Interface) framework for various driving conditions. We propose an all-around sensing based on the integrated DAS that can also remove the blind spots using 2 cameras and 8 sonars, recognize the driving environment by lane and vehicle detection, construct a novel birds-eye HMI for easy comprehension. it can give proper warning in case of imminent danger.

This paper's purpose is three-folded: modeling the self-regulating fire prevention system, developing a packet of practical fire prevention measures and regulations, and reviewing the applicability of fire insurance system in Korea as a main components of the self-regulating fore prevention system. The so called self-regulating fire prevention system is defined as a grand national fire prevention framework based on and promoted by the vitality and creativeness of the market (or private sector). This drastically contrasts with the existing government-led fire prevention system in Korea. The self-regulating fire prevention system has three grounds: the principle of self-responsibility, the redefinition of the fire service as a public goods, and the principle of self-selection. It seems natural that the self-regulating fire prevention system requires the function of fire insurance institution as a pivoting mechanism providing individual decision makers with a system of incentives, resulting in rational behaviors in the part of each individuals and in the well-balanced fire prevention network in the part of the overall public. In this regard, this pilfer examines the institutions and performance of the fire insurance industry in Korea and reviews the limitation of the industry as an instant replacement mechanism of the current government-led fire prevention system in Korea.

With the emergence of world wide web, in particular web 2.0 the rapidly growing amount of news articles has created a problem for users in selection of news articles according to their requirements. To overcome this problem different clustering mechanism has been proposed to broadly categorize news articles. However these techniques are totally machine oriented techniques and lack users' participation in the process of decision making for membership of clustering. In order to overcome the issue of zero-participation in the process of clustering news articles in this paper we have proposed a framework for clustering news articles by combining users' judgments that they post on twitter with the news articles to cluster the objects. We have employed twitter hash-tags for this purpose. Furthermore we have computed the credibility of users' based on frequency of retweets for their tweets in order to enhance the accuracy of the clustering membership function. In order to test performance of proposed methodology, we performed experiments on tweets messages tweeted during general election 2013 in Pakistan. Our results proved over claim that using users' output better outcome can be achieved then ordinary clustering algorithms.

The purpose of this study is to investigate women's radio talk program and evaluate its possibilities and limitation from the point of feminist perspective. The theoretical framework is based on feminist studies and text analysis of talk show. Existing studies regarding talk show are mainly focused on television. But radio talk show is one of general entertainment and it's influences on minorities are still significant. is the most representative women's radio talk program in Korea. It has been broadcasted over 10 years and very popular among Korean housewives. The audience of this program call themselves schoolfellow, and call the program 'school of women'. The media text of is mainly consisted of letters from women audiences, and they are selected by producers. So the text is made by both audiences and producers. The unique combination of this process produces complicated discourses which contain women's experiences in letters and station's considerations through safekeeping. The problems investigated in this study are as follows: First, What discourses are produced in this program? Second, Alternative possibilities can be seen in this program in feminist perspectives? Text analysis of 1week(2000.9.18-9.24) and interview with producers are accomplished to this purposes. In the text analysis, subject matters, inscribed women's position, values of the letters are revealed. Most of the subject matters are family affairs. Some are socially oriented but family and home are the predominant category of women's letters. And the position of women subject is defined in the domestic network. They are nameless but the mother, wife, daughter, daughter-in-law of other people. In value, family-oriented value and small happiness in everyday life are generally appeared. But these values are essentially coincide with the values of status quo. The answers of the conflict are not public but individualized. And acception the status quo is presented as the wisest decision, But ` has many implications in relation to women's sharing of their experience, and construction of imagined community in media. Women continuously interact each other revealing and discussing their experiences and sometimes their social practices are stirred through this media sphere. So we see the 'emotional union' among women are formed through radio. The limitation of this program is very apparent: it's patriarchic values, acception of status quo, and individualization of the women's problems. But in the same time we can read coexisting it's latent possibilities: the possibilities of women's public sphere. But it is completely alternative women's sphere in feminist perspectives. It renders women opportunities to participate public media and share with other women, and collaborate with their problem.

This study investigated the factors affecting the procedures of becoming a scientist. Interview was used as a research method for deep understanding of individual career choice procedures. Interviews for individual scientists were conducted for about 60 minutes in their offices and all the interviews were tape-recorded. A total of 34 scientists who received some representative science awards in Korea during 1990 - 2001 were sampled. They were all men. But the interview was conducted with 30 scientists. The investigation was based on the framework that was composed of the following four categories: personal ability, home environment, school environment, and sociocultural environment. And each category had several factors as follows: personal ability consisted of the meta-ability to figure out the aptitude and the self-ability and the achievement; home environment consisted of parents, brothers and sisters, relatives, and hobby; school environment consisted of teachers, friends, club activity; sociocultural environment consisted of event, mass media, social recognition and social prospect. From the analysis of the career choice procedure of the scientists it was appeared that the meta-ability for personal ability, the parental influence particularly by father for home environment, science teacher and professor for school environment, and social prospect for sociocultural environment were important. In conclusion, most of the scientists made an important decision for their future career when they were the 12th grade and 1st year in university, and they considered intrinsic factor such as self-interest and aptitude and extrinsic factor such as social prospect. However intrinsic factor related to science teacher and professor and extrinsic factor related to fathers' advice.

One of the major causes of morbidity and mortality in breast cancer patients is delay in seeking help. Leventhal's self-regulation model provides an appropriate framework to assess delay in seeking help. The aim of this study was to investigate the relationship between "illness perception" and "help seeking delay" in breast cancer patients based on Leventhal's self-regulation model. In this correlational descriptive study with convenience sampling conducted in 2013, participants were 120 women with breast cancer who were diagnosed in the last year and referred to chemotherapy and radiotherapy centers in Rasht, Iran. Data collection scales included demographic data, Revised Illness Perception Questionnaire (IPQ-R)and a researcher made questionnaire to measure the delay in seeking help. Pre-hospital delay (help seeking delay) was evaluated in 3 phases (assessment, disease, behavior). The data were analyzed using SPSS-19. The mean (SD) age calculated for the patients was $47.3{\pm}10.2$. Some 43% of the patients had a high school or higher education level and 82% were married. The "pre-hospital delay" was reported ${\geq}3months$. Logistic regression analysis showed that none of the illness perception components were correlated with appraisal and behavioral delay phases. In the illness delay phase, "time line" (p-value =0.04) and "risk factors"(p-value=0.03) had significant effects on reducing and "psychological attributions" had significant effects on increasing the delay (p-value =0.01). "Illness coherence" was correlated with decreased pre-hospital patient delay (p-value<0.01). Women's perceptions of breast cancer influences delay in seeking help. In addition to verifying the validity of Leventhal's self-regulation model in explaining delay in seeking help, the results signify the importance of the "illness delay phase" (decision to seek help) and educational interventions-counseling for women in the community.

The purpose of this study was to develop Intensive Care Unit (ICU) admission and discharge criteria that would lead to the appropriate utilization of ICU resources and nursing services. For this study, a conceptual framework was developed through a review of the literature. Then in order to identify the overall health condition of patients in the ICU, and to draw up preliminary criteria, the medical records of 58 patients who were admitted to the ICU of Y Medical Center in Seoul between March, 1999 to February, 2000 of were analyzed. Two expert validity tests were done for the preliminary criteria for admission and discharge with 21 patients over 18 years of age who were admitted patients and for 12 patients who were discharged between May 30, 2000 and June 5, 2000 a clinical validity test was also done. After this process, the final admission and discharge criteria were developed. The results of this study are summarized as follows: 1. After a review of the literature, there were 9 categories for admission criteria cardiologic, gastrointestinal, neurologic, endocrine, post-op care of major surgery, vital signs, laboratory values, and a category of miscellaneous items. Discharge criteria had 3 categories which were vital signs, laboratory values, and a category of miscellaneous items. 2. From the medical records of the 58 patients who were admitted to the ICU, 45 items for preliminary criteria for admission and 17 for discharge were identified. 3. The two expert validity tests showed that of the 45 items 29 admission items received over 75 percent agreement. The 16 admission items which received less than 75 percent agreement were revised or deleted from the admission criteria. Of the 17 discharge items, 11 had over 75 percent agreement and 6 less then 75 percent agreement. These were revised or deleted from the discharge criteria. 4. In the clinical validity test, 14 admission items showed more than 75 percent agreement and 11 discharge items more than 83 percent agreement. 5. The final criteria consisted of 29 items for admission and 11 items for discharge. Since patients being considered for admission to the ICU have complex problems, there is a need to make the decision based on more than a single issue. This tool will insure that the ICU nursing care and treatment resources are appropriately used by allowing a multi-professional health team to make admission and discharge decisions.
