The server privilege account must be operated through law and regulation. However, due to regulation non-compliance and inadequate operation on financial company server privilege, an incident that every server data being deleted by hacker occur which is later being named as 'NH Bank Cyber Attack'. In this paper, the current operation status on financial company privilege accounts is being analysed to elicit problems and improvement. From the analysis, important evaluation factors will be also selected and applied generating the decision making model for financial company server privilege account operation. The evaluation factor deducted from privilege account status analysis will be used to present and verify the decision making model and formula through AHP(Analytic Hierarchy process).

BACKGROUND/OBJECTIVES: We investigated the effect of Pycnogenol (Pyc) on survival and immune dysfunction of C57BL/6 mice induced by low micronutrient supplementation. MATERIALS/METHODS: Female C57/BL/6 mice were fed a diet containing 7.5% of the recommended amount of micronutrients for a period of 12 wks (immunological assay) and 18 wks (survival test). For immunological assay, lymphocyte proliferation, cytokine regulation, and hepatic oxidative status were determined. RESLUTS: Pyc supplementation with 50 and $100mg{\cdot}kg^{-1}{\cdot}bw{\cdot}d^{-1}$ resulted in partial extension of the median survival time. Pyc supplementation led to increased T and B cell response against mitogens and recovery of an abnormal shift of cytokine pattern designated by the decreased secretion of Th1 cytokine and increased secretion of Th2 cytokine. Hepatic vitamin E level was significantly decreased by micronutrient deficiency, in accordance with increased hepatic lipid peroxidation level. However, Pyc supplementation resulted in a dose-dependent reduction of hepatic lipid peroxidation, which may result from restoration of hepatic vitamin E level. CONCLUSION: Findings of this study suggest that Pyc supplementation ameliorates premature death by restoring immune dysfunction, such as increasing lymphocyte proliferation and regulation of cytokine release from helper T cells, which may result from the antioxidative ability of Pyc.

Purpose: This study was done to identify the relationship between emotional intelligence (EI) and job stress of clinical nurses in small to medium-sized hospitals. Methods: Data were collected from a convenience sample of 152 nurses working in 4 local public hospitals in one district. EI was measured with the scale developed by Law, Wong, & Song (2004), and job stress with the scale by Choi, Kang, & Woo (2006). Data were analyzed with PASW (SPSS) 18.0, using descriptive statistics, t-test, ANOVA, Scheffe' test, Pearson correlation coefficients, and multiple regression. Results: There were significant differences in EI according to work time, in self-emotional appraisal according to salary, in regulation of emotion according to marital status, age, work time, and salary. There were also significant differences in job stress including somatization, depression and anger according to marital status, work time, and salary. Correlation between EI and job stress was negative. EI explained 17.3% of variance in job stress. Conclusion: The findings indicate that to decrease job stress, nursing managers need to develop EI, especially self-emotional appraisal and regulation of emotion for nurses in their twenties and for unmarried nurses.

Purpose: This study was designed to identify the prediction factors that influence nurses' organizational commitment. Method: The sample of this study consisted of 526 full-time nurses randomly picked at 19 general hospitals in Korea. The data was analyzed by computer using SPSS 15.0 for Pearson's correlation coefficient, and multiple regression analysis. Result: 1) According to general characteristics, nurses' organizational commitment levels among the sample were significantly different in age, religion, social status, marital status, clinical career, and department satisfaction. 2) Level of nurses' organizational commitment was average 2.70, job satisfaction 2.91, burnout 3.03, empowerment 3.36, autonomy 2.93, and self-efficacy 3.51. 3) Nurses' organizational commitment had significant positive correlations with job satisfaction, empowerment, self-regulation, social support, self-efficacy, clinical career, and personnel movement experience. On the other hand, it had significant negative correlations with occupational stress, burnout, and age. 4) The prediction factors which influence Nurses' organizational commitment were job satisfaction($\beta$=.405), burnout($\beta$=-.282), self-regulation($\beta$=.171), clinical career($\beta$=.135). These factors were approximately 49.6% reliable in explaining nurses' organizational commitment. Conclusion: These results can be used to develop hospitals' management strategies for increasing organizational commitment effectiveness and nursing productivity.

This review discusses the status, antimicrobial mechanisms, application, and regulation of natural preservatives in livestock food systems. Conventional preservatives are synthetic chemical substances including nitrates/nitrites, sulfites, sodium benzoate, propyl gallate, and potassium sorbate. The use of artificial preservatives is being reconsidered because of concerns relating to headache, allergies, and cancer. As the demand for biopreservation in food systems has increased, new natural antimicrobial compounds of various origins are being developed, including plant-derived products (polyphenolics, essential oils, plant antimicrobial peptides (pAMPs)), animal-derived products (lysozymes, lactoperoxidase, lactoferrin, ovotransferrin, antimicrobial peptide (AMP), chitosan and others), and microbial metabolites (nisin, natamycin, pullulan, ε-polylysine, organic acid, and others). These natural preservatives act by inhibiting microbial cell walls/membranes, DNA/RNA replication and transcription, protein synthesis, and metabolism. Natural preservatives have been recognized for their safety; however, these substances can influence color, smell, and toxicity in large amounts while being effective as a food preservative. Therefore, to evaluate the safety and toxicity of natural preservatives, various trials including combinations of other substances or different food preservation systems, and capsulation have been performed. Natamycin and nisin are currently the only natural preservatives being regulated, and other natural preservatives will have to be legally regulated before their widespread use.

In this paper we proposed the on line volt/var control schemes of the load Tap Changer (LTC) transformer and shunt capacitor bank for distribution volt/var regulation. In the existing volt/var control of the distribution substation, the voltage of feeders and var of distribution systems is mainly controlled by the LTC transformer tap position and on/off status of the shunt capacitor. The LTC and shunt capacitor bank has discrete operation characteristics and therefore it is very difficult to control volt/var at the distribution networks within the satisfactory levels. Also there is limitation of the operation times of the LTC and shunt capacitor bank because it is affects on their functional lifetime. The proposed volt/var control algorithm determine an optimal tap position of LTC and on/off status of shunt capacitors at a distribution network with the multiple feeders. The mathematical equations of the proposed method are introduced. Simple case study was performed to verify the effectiveness of the proposed method.

Nutrition fortification of processed foods with microelements is a popular practice in many countries to improve nutritional status of target population. In this study the current food fortification in Korea was evaluated and the regulations and guidelines for food fortification in other countries were presented. Most commonly added nutrients were calcium, vit.C, fiber, vit.Bs and iron. The level of fortified nutrients and the vehicle foods were variable. vit.C and fiber appeared to be overfortified in some foods and the necessity of fortification of these nutrients needs to be examined since the intakes of these elements appears to meet the RDA. Most of other nutrients such as vit.A, vit. $B_1$, vit. $B_2$, and iron were added at the level of 10~25% RDA per serving size. The vehicle foods for fortification were snacks, milk, ramyun, breakfast cereal, juices, candies and ready-to-eat retort pouch foods but not rice which is a staple food in Korea. The guideline and regulation for food fortification is required to ensure safe and proper supplementation of needed nutrients in processed foods.

In this paper the consumer protection regulations of 16 wide area self-governments in Korea are studied. Status of consumer protection policy committees and their general policies for consumer protection of these wide area self-governments are also investigated. The data of consumer protection regulation were collected from the internet web-site of each self-government and the status of consumer protection policy committee and the general policy for consumer protection were obtained by requesting each self-government to report administration information during May through October in 200l. 13 of 16 wide area self-governments except Daegu, Inchon, and Jejudo have own consumer protection regulations. Major parts of these regulations conform the standard regulation of ministry of Government Administration and Home Affairs. Many of the consumer protection policy committees reported that they do not have meetings constantly. Moreover since the price of goods and services is the typical subject of meetings, the committees do not seem to properly play the role of a consumer protection policy authority. Contents of the general policy for consumer protection of many self-governments are simple description of detailed practicing plans according to the general consumer protection policy of the national government. By criticizing the problems aroused during the study of consumer protection policy of self-governments, suggestions are given which will help for the development of consumer policy of wide area self-governments.
