Chrominum(cr) plays an important role in carbohydrate and lipid metabolism and Cr deficiency impairs glucose tolerance and increase serum cholestrol and triglyceride. The relationships of serum Cr with serum glucose and lipids was examined in 79 female college students in Choong-Nam ares. Subjects were devided into underweight. normal and overweight groups according to their BM11. The average age, weight, height and BMI were 21.9yr, 55.89kg, 158.54cm and $22.62kg/m^2$, respectively. Height were not di fferent between groups. Serum Cr and glucose concentrations were not signi ficantly different between groups. However, there were tendency of increasing serum Cr level with increasing body weight. Serum cholesterol and LDL-cholesterol concentrations were significantly lower in underweight group than other groups. BM! had positive corelations wi th LDL-cholesterol, Al and LPH, and negative corelations with HDL-cholesterolltotal cholesterol ratio. Serum Cr concentration had positive corelation with serum glucose concentration and negative corelation with LDL-chloestrol and LPH.nd LPH.

Objectives : The purpose of this study was to show the corelation between age-related muscular mass and the change of exercise, muscle mass and muscular strength by comparison of muscle strength. Methods : 39 volunteers of all the patients who come to Dangjin health center between May and June in 2009 were classified as group A and group B according to age. Demographic data of these two groups have been done a comparative analysis, using the t-test procedure and linear regression analysis. Results : The results and summarized as follows. 1. Demographic data of these two groups have been done a comparative analysis, using the t-test procedure. As a result the average exercise and the average pulse have a statistically significant difference according to age. 2. Each of average fat, muscle and muscular strength in these two groups have been done a omparative analysis, using the t-test procedure. As a result there is no statistically significant according to age. 3. According to the result analyzed by using linear regression analysis, age have a negative effect on muscle but there is no statistically meaningful. Exercising have a positive effect on muscle and there is statistically significant. 4. Age and Protein diet have a negative effect on Grip strength but there is no statistically significant Conclusions : From this result, it can be assumed that the amount of exercise is decreasing with age, which leads to lose some muscle mass.

This paper tried to understand the effects of alcohol-reducing program on drinkings behaviour of workers on works under 5 employees. For these, this paper understood a change of drinkings custom and degree of alcohol-reducing strategy practice by enforcement of alcohol reducing program over 7 times during 3 months Reaults from analyses are as follows 1) A health problems related to drinkings were a chronic fatigue and indigestion, 15.5% was over 5 items among items related to liver disease. 2) The subjector of investigation all was involved over 2 items among items that a drinking custom must be collecred. 3) The change of drinkings custom between before and after on enforcement of alcohol reducing program showed a effective difference. 4) For a degree of the alcohol-reducing strategy practice, "reducing drinkings days" was 82.9%. "bearing drinkings impulse" 70.7%, "exchanging drinkings custom" 56.1%, "avoiding drinkings friends" 51.2%, Yet, "avoiding drinking place" and "preparing leisure activity to exchange drinkings" showed a low practice ratio. 5) For correlation between drinkings drinkings behaviour and degree of alcohol-reducing strategy practice, the more drinkings times before program paticipatance the higher alcohol-reducing strategy practice, alcohol dependency and drinkings times, alcohol-reducing strategy and drinkings times, befere drinking custom had an effective negative corelation, after drinkings custom and alcohol-reducing strategy a strong effective positive corelation. 6) workers writing drinkings paper decreased drinkings times. Implications from results are as follows The alcohol-reducing program is necessary to works under 5 employees, and needs to he operated continously. Especially, in works under 5 emplyees, the alcohol-reducing programt needs to be operated by firm or government.

In this paper, an contemplate the direction for Usable Security in IT security and User Experience. To evaluate how the user interface is convenient to use, we examine the components such as the property, learnable property, memory simplicity, faults and satisfaction level. By considering for the security, we should bring positive effects on the user experience. By emphasizing usability and security at the same time, we should increase the satisfaction level of the user experience and then produce the valuable experience through participation, use and observation. The positive user experience is the important task for the software engineering, business administration and others., and this will result satisfaction of the users, brand trust, and success in the market. On the other hand, for the negative user experience, the users cannot achieve their desired goal and therefore, are unsatisfied due to emotional, rational and economic inconvenience. Due to this, we should try to maintain a certain level of usability and security of the system in IT security and User Experience.

In order to effectively manage the reservoir, reservoir water quality management should be based on physicochemical and configurational characteristics. In this research, correlation between factors affecting the reservoir water quality was examined. Chl-a and COD shows the highest positive correlation. Chl-a and T-P also has a high positive correlation, however Chl-a and T-N show lower correlation relatively. Even though T-N is an important factor for phytoplankton growth which increase Chl-a concentration, corelation of Ch1-a and T-N shows that enough nitrogen in the reservoir isn't no longer limiting factor. The age of reservoir can cause of increasing COD and SS. Embankment height and elevation of reservoirs shows strong negative correlation to water quality. That means reservoir which is higher embankment height and locate in higher elevations is less contaminated. Regression expression was derived with Chl-a and water quality parameters, and height of reservoir. Finally Chl-a was simulated using regression expression and it was a good approach to predict the Chl-a concentration.

Purpose: This study was to identify the levels of functional status, depression, family support and their relationship among those variables in head and neck cancer patients. Method: The subjects were 100 patients with head and neck cancer patients who visited at outpatients clinic in one university hospital in Taegu. The instrument used for this study were Functional Status in Head & Neck Cancer - Self Report Scale developed by Baker(1995), Self-Rating Depression Scale by Zung(1965) and Family support assessment tool by Kang hyun-suk(1984). The data were analysed percentage, mean, t-test, ANOVA and pearson's corelation using SAS program. Result: There was significantly negative correlation between functional status and depression(r=-.71) and between depression and family support(r=-.56). The relationship of functional status and family support was significant as r= .33. Conclusion: It was found that functional status, depression and family support of head and neck cancer patient were closely related each other. Therefore it is necessary to design nursing intervention to enhance family support or decrease depression for improving quality of life in head and neck cancer patient.
