As XML is becoming a de facto standard for distribution and sharing of information, the need for an efficient yet secure access of XML data has become very important. To enforce the fine-level granularity requirement, authorization models for regulating access to XML documents use XPath which is a standard for specifying parts of XML data and a suitable language for both query processing. An access control environment for XML documents and some techniques to deal with authorization priorities and conflict resolution issues are proposed. Despite this, relatively little work has been done to enforce access controls particularly for XML databases in the case of query access. Developing an efficient mechanism for XML databases to control query-based access is therefore the central theme of this paper. This work is a proposal for an efficient yet secure XML access control system. The basic idea utilized is that a user query interaction with only necessary access control rules is modified to an alternative form which is guaranteed to have no access violations using tree-aware metadata of XML schemes and set operators supported by XPath 2.0. The scheme can be applied to any XML database management system and has several advantages over other suggested schemes. These include implementation easiness, small execution time overhead, fine-grained controls, and safe and correct query modification. The experimental results clearly demonstrate the efficiency of the approach.

This paper examined some problems of media coverage of religion by analyzing a television documentary. The SBS-TV documentary "God's way Man's way" aired in 2008, critically presented the basic Christian doctrine. The producers of the program estimate that protestant churches in Korea have become an established power, which has influence on a societal and political level. Therefore the producers believe that they have the right to criticize that power, especially because its doctrine about salvation leads to serious conflict with other religions, for example, Islam. This program portrayed the doctrine of Jesus as a story borrowed from ancient myths. Consequently, there were harsh protests from the Korean Christian milieu, especially protestants. The author agrees that it is important for the media to critically cover the activities of religious institutions and the behaviors of religious people in the civil society. However, if producers of a documentary want to introduce controversial doctrines of one religion to an audience, they should present the orthodox ones with alternatives or opposing ones, according to the principle of objectivity and fairness of journalism. Since every religion has its mysterious doctrine that cannot be proven by science and reason, journalists should not criticize the sacred part of religion. This paper suggested some ethical points to the media, children of Enlightenment Age, when they cover the religion including its doctrine and mysterious parts.

Manufacturing facilities of the pharmaceuticals must meet certain level of the cleanness required so that foreign substances such as dust, moisture, heat, microorganism, or virus do not contaminate the product. In case of radiopharmaceuticals for medical treatment and diagnosis, not only should the operators and environment be protected from radiation but also need to be isolated from the foreign contaminant. Therefore, manufacturing facilities for radiopharmaceuticals must satisfy the design standards of both hot cell and clean room which are specified by GMP. However, standards of maintaining negative pressure for preventing spread of radioactive contaminant in isolated facilities conflict with the standards of maintaining positive pressure for keeping cleanness. To solve this problem, air pressure of hot cell was designed lower than in the adjacent area to meet standards of the radiation safety. To keep higher cleanness in certain part of the hot cell for filling, minimal relative positive pressure allows. In order to effectively maintain the cleanness that is required for production of Tc-99m generator, which takes 70% of whole demand of radiopharmaceuticals, the rooms placed in each side of production room are used as a buffer area and three lead hot cells are installed in production room. In this research, we established the appropriate engineered design concept for Tc-99m generator manufacturing facility, which satisfies both GMP cleanness standard for preventing particles, bacteria, other contaminants and the regulations of radiation safety for supervising and controlling the amount of radiation exposure and exhausted radioactivity. And the concept of multi-barrier buffer zones is introduced to apply negative air pressure for hot cell with first priority and to continue relative positive air pressure for clean room.

This paper analyzes the two cases of labor disputes (Hyundai Motor in 1998 and Power Generation Companies in 2002) in the period of restructuring, by applying the behavioral theory of labor negotiations as a comparative framework. The paper compares th backgrounds of the labor disputes, core issues, bargaining processes, and evolutionary patterns and consequences of the labor disputes at the two cases. The common features, found in the two dispute cases, are strong mistrust and exclusive bargaining attitude between labor unions and management, little feasibility of contract zone in bargaining proposals by the two parties, heteronomous dispute resolution by the intervention of the government, and the lack of learning effect gained from the experience of labor disputes. This comparative case study identifies that the confrontational labor-management relations at the firm level is re-produced by a regressive process of the following circulation: labor-management distrust $\rightarrow$ interest conflict in bargaining demand $\rightarrow$ exclusive bargaining attitude $\rightarrow$ the experience of antagonistic dispute $\rightarrow$ deepened distrust. In conclusion, four parties-labor unions, management, the government, and public press - are required to make much effort to replace the vicious circle of labor-management confrontation by a virtueous cycle of labor-management cooperation.

This study explained about the different motive of partner homicide and this homicide's elements which are feature of human sociology, home environment, school life and partner's trouble causes. After analyzed these element which affect to the motive of partner homicide, we couldn't find statistical differences of partner homicide motive by sex, having a job. However, there are small gap in an age group. Almost the homicide by expressive motive was a primary factor in the whole mass but, in the age of 40's, 11.1% is by the homicide of instrumental motive in the partner homicide. We need some more detail analysis and the partner murderer who growed up in very poor home circumstances commit Homicide by 100% expressive motive. This result suggested that murderer who was in the inferior home environment can do murder more easier than normal because of their emotional reason which are urgent, impulsive and contingent. On the other hand, their school life behavior during a growth process was useless for explain the motive of partner homicide. On one side, we could confirm that partner's trouble cause is a very useful element for explain the partner homicide, that is, if the if the level of conflict with partner's were high, the murder by expressive motive will grow up. But we must see the fact that the partner homicide's rate is 13.3% by instrumental motive in the low trouble causes very carefully for understand the partner homicide.

The purpose of this study is to develop the U-turn accident model at signalized intersections in urban areas. The characteristics of the accidents which are associated with U-turn operation at 3 and 4-legged signalized intersections was analyzed and the U-turn accident model was developed by regression analysis in Changwon city. First, in order to analyze the effectiveness on traffic accidents by U-turn installation, the difference of mean of traffic accident number are measured between two groups which are composed by whether or not U-turn installation the groups by Mann-Whitney U test. The result of significance test showed that intergroup comparison on mean by accident types made difference except rear-end accident type and by accident locations exit section only showed difference in significance level at 4-legged intersections, so the accident number have more where the U-turn is permitted than not. Response measures about the number of accidents were classified by whether accidents occurred and accident model were constructed using binomial logistic regression analysis method. The developed models show that the variables of conflict traffic, number of opposing lane are adopted as independent variable for both intersections. The variables of longitudinal grade for 3-legged signalized intersection and number of crosswalk for 4-legged signalized intersection at which the U-turn is permitted is adopted as independent variable only. These study results suggest that U-turn would be permitted at the intersection where the number of opposing lane is more than 3.5 each, the longitudinal grade of opposing road is upward flow and there is need to establish the U-turn traffic sign at signalized intersections.

Femvertising campaigns are more easily observed in oversea rather than in Korea. Most recently, not only global companies but local consumer goods companies launched several femvertising campaigns. However, no research was done on effects of femvertising in Korea. Thus, this study will explore Korean college students' understanding of, attitude toward, and effects of femvertising through focus group interviews. Study results found that college students have low level of understanding on the concept of femvertising. However, they are somewhat familiar with contents of femvertising. Femvertising is believed to have positive impacts on gender equality and female empowerment whereas there are growing concerns over commercializing feminism. Study participants, regardless of gender, suggest that femvertising could influence consumers' attitude toward advertising and brand, but they are skeptical of purchase intention. Lastly, female participants suggest that femvertising, compared to traditional advertising, will enhance attitude toward ads and brand, and even have a positive impact on feminism. However, male participants suggest that femvertising may exacerbate the gender conflict between males and females which is called as 'misandry' or 'misogyny'.

This study examined the relationship between the experience of stressful life events and somatic symptoms of urban women. Data were collected by interviewing 200 women from June to July 1, 1991. Vsable data work obtained from 162 of the women. Modified version of a stressful life events measurement tool developed p.5. Lee (1984) and the Somatic Discomfort Inventory by Wittenborn were used to measure the variables. Data were processed by an 5.p.5.5. program and analyzed. statistically for percentage, T-test, ANOYA and Pearson Correlation coefficient. Result of the Study are as follows : 1) The group total mean score of stressful life events was 92.66 $\pm$ 10.41. The higher scores in the $\boxDr$Test and school$\boxUl$ of the Extrapersonal factor, in the $\boxDr$Health problems$\boxUl$ of the Intrapersonal factor and $\boxDr$Conflict and differences within the family$\boxUl$ of the Interpersonal factor, factors. which a suggested by Neuman's model. 2) The group total mean score for somatic symptoms was 100.41$\pm$9.74. The higher scores were for the factors of $\boxDr$Fatigue (1.94)$\boxUl$, $\boxDr$Menopause (1.74)$\boxUl$, $\boxDr$Muscular system(1.67)$\boxUl$ and $\boxDr$Sleeping (1.67)$\boxUl$ 3) The mean scores of stressful life events were higher in the 40~60 age group, for middle school graduates(P＜.05), career women and those in nuclear families (P＞.05). 4) The mean scores of somatic symptoms were higher in the 45~60 age group, for middle school graduates, non career women and women with 5 or more children(P＜.05). 5) There was a positive correlation between the scores of stressful life events and somatic symptoms (r＝.585 P＜.05). The higher the level of stressful life events the higher the score of somatic symptoms, the results were consistent with the Extrapersonal, Intrapersonal and Interpersonal stress factors of Neuman's Health Care Systems. This research assessed the stressful life events of women, who play the most important role in the family for illness prevention and health promotion and suggested the importance of programs in the Primary Health Services to build basic coping resources.

The aim of this study is to demonstrate how Self-Sufficiency Promotion Centers (SSP Centers) run by social movement groups have struggled to defend their voluntary identities in conflict with SSP Centers operated by professional social welfare centers. Since political democratization, social movement groups have been increasing invited to run frontline public welfare agencies in South Korea, and Self-Sufficiency Program is one of the representative policies in which social movement groups have actively partaked. But many critical scholars have warned that such institutionalization of social movements into social welfare system is likely to dampen their voluntary nature and force them to render their hegemonic power to professional social welfare institutions. In contrast to the critical viewpoint, however, this study unveils how social movement-based SSP Centers have strived to tackle the professionalization pressure by deploying various survival strategies at the micro level. Through a historical discourse analysis on the frontline conflicts between social movement-based and social welfare-based SSP Centers, this study contends that social movement groups in Self-Sufficiency Program can still maintain their traditional spirit despite the obvious professionalization phenomenon.

Changes in a drug's availability from prescription only to over-the-counter (OTC) status is of concern to physicians from both public health and individual patient perspectives. Government has generally been supportive of changes in medications from prescription(Rx) to over-the-counter (OTC) status in Korea, however, recognizing that there are both benefits and risks to any health care intervention, health care professionals are conservative in implementing changes to either the process or structure of health care. Changes in status of a drug from Rx to OTC can represent a change in both structure and process. Cost and convenience seem to be major factors in determining whether, given the choice, patients purchase a medicine over the counter or obtain it on prescription. With current arrangements, exemption from prescription charges provides an incentive to continue to obtain products on NHS prescription even when they are available over the counter. There is therefore no simple relation between the availability of over the counter medicines and the level of prescribing of deregulated products. The appropriate use of over the counter medicines-particularly those that have only recently been deregulated-places a burden of care on community pharmacists and calls for closer working relationships with general practitioners. In particular, systems for referral and for recording details of both prescribed and over the counter medicines need to be developed, and a direct route needs to be established for community pharmacists to report adverse drug reactions to over the counter products. Reclassification of prescription medicines-by making them available through pharmacies without a prescription-provides the opportunity for consumers to purchase a wider range of medicinal products without making a demand on NHS resources. There is, however, no simple relation between availability of over the counter medicines and demand for NHS prescriptions. In the late 1980s the UK government fuelled the over the counter market by making it easier to reclassify certain medicines from prescription only status to allow over the counter sale in pharmacies. To explore the influence of deregulation of medicines on NHS prescribing, this article presents analyses of consumer behaviour in using medicines and prescribers' attitudes to over the counter medication and collates findings from research. Policy makers should be aware that patients' expectations in relation to OTC medicines may be in conflict with evidence-based practice.
