Power-saving PC software enables the inexpensive power control, but the installation of the power-saving software in all computers in the organization is not an easy task. Computer users in the organization are usually not cooperative as they do not think the power-saving cost is directly related to themselves. The PC power-saving system provides advantage to driving active participation in which users installs the power saving software by restricting IP address through the power management server. However, the problem with this approach is the security vulnerability to IP spoofing attacks, therefore we need to solve the problem that disrupt the entire network system rather than saving electric power. This paper proposes the security authentication system that can implement the efficiency saving power by providing high security for the members' computer system of the public institutions based on the PC power-saving system. Also, by analyzing it in comparison with other method, it is possible to check that the prospects of safety and efficiency are strengthened.

This research investigates the effect of leisure activities on lifestyle satisfaction of senior citizens. The target of this research is 202 people over 60 years of age who live in Seoul. Collected data was analyzed using frequency, percentage, average, T-test, one-way ANONA, and logistic regression analysis. SPSS and the Excel PC Program were used for the analysis. The following is the summary of the result of this research. First - in terms of participation in leisure activities: more active participation is observed with the elderly who have a spouse than with those who do not in every kind of leisure activity (except for the pastime activities). Second - all of the variables indicating the level of satisfaction from activities of the seniors who have a spouse are by far higher than those of the elderly who have no spouse. Third - the leisure activities and the satisfaction from the activities prove affective variables on whether they have a spouse or not. Notably, the religious leisure activities are enjoyed more by those senior citizens who are married. Comparatively, the unmarried senior citizens participate more actively in recreational and pastime leisure activities. This study suggests various practical means to promote leisure activities to the elderly and to raise the level of satisfaction received from those activities, as well as to help those who are concerned with understanding and improving lifestyle satisfaction of the elderly population. Nonetheless, this analysis is limited due to the restriction on the number of objects and samples studied. Therefore, studies to analyze leisure activities by regions in order to account for a more balanced set of systematical tools should follow.

Objectives : Generally, it seemed that the therapeutic result in diabetic patients was changed by compliance. This study was conducted on the basis of assumption that the therapeutic result id diabetic patients could control according to compliance. This study was conducted to analyze the related factors in association with compliance to drug, diet and exercise therapy. Methods : 224 diabetic patients in Kyungpook National University Hospital were selected through the interviews and HbA1c values from 1 Jan. to 28 Feb.1997. The drug compliance was tested by regularity of drug administration, the diet compliance was tested by restriction of food, exactly allocation, balance of nutrient, measuring food and the exercise compliance was tested by regularity of exercise per day. We assessed compliance by percentage, $x^2-test$ and generalized logit regression model(method:enter). Results : The significant variable was the satisfaction to medical personnels in drug, the knowledge to disease in diet, the participation of the diabetic education in exercise therapy and the satisfaction to medical personnels in HbA1c. Using the generalized logit model(method : enter) in compliance change, the significant variables were the satisfaction to medical personnels and the complication in drug; the significant variables were the age at the first diagnosis, the family history, the concern of health, the knowledge of disease, the self-exertion for therapy and the complication in diet: the only significant variable was the gender in exercise therapy. Conclusions : The degree of glycemic control in diabetic patients was influenced by compliance. In order to improve patient's compliance, we must foster the knowledge on the diseases, lead participation for diabetic education. Because the satisfaction to medical personnels was the important variables, we must build up good relationship between doctors and patients.

The purpose of this study is to investigate the level of perceived self-esteem and maternal caretaking behaviors of college students. Data were collected through self-report questionnaires in which maternal caretaking behaviors and self-esteem were included. This study chose 293 students studying at universities and a college in Busan and a college in Taebaek as subjects. The data were analyzed by the SPSS program. The results were as follows ; 1. The mean score of the subjects on self-esteem was 29.6(Range=10-40). 2. The mean score of the subjects on maternal caretaking behaviors was 82.7(Range=22-110). The mean scores of subsets on the maternal caretaking behaviors were as follows ; achievement(4.03), affection(3.86), rational direction(3.79), active participation (3.60), consistent restriction(3.59), authoritative control(3.49) and over-protection(3.28). 3. The level of maternal caretaking behavior revealed some difference according to the students' gender and their mothers' academic career. 4. The level of self-esteem was positively correlated to the level of maternal caretaking behaviors in subjects. In conclusion, the above findings indicate that mothers' positive pattern of maternal caretaking behaviors are closely related to the students' higher self-esteem.

Despite very good reputation that Korean construction industrial firms had enjoyed until early 1990's in overseas markets, their participation abroad drastically declined after the delivery of two(2) million unit-housing project in the early 1990's and the foreign currency crisis that took place in the late 1990's. The revival of booming construction industry in domestic market is far beyond the expectation due to the long recession of the construction economy and government's severe restriction against real estate development. Under such crucial circumstances, the construction industrial firms' strategy to survive is the more active business promotion in overseas markets. However, the Korean construction industrial firms have to abandon the labor intensive strategy, through that they have enjoyed until the early 1990's, and turn to management oriented strategy which may be a new prosperous horizon and a new challenge as well, because the labor cost of newly developing countries is much more competitive. The aim of this study is to suggest how to cope with current market situations through a chronological survey based on the cost data prevailed during four decades from the 1960's until the 1990's in overseas markets.

This paper presents an advanced load control method in Direct Load Control(DLC) system. It is important to aggregate a various demand side resource which is surely controllable at the peak power time for a successful DLC system. Because the DLC system use simple On/Off control that may cause a harmful effect on a plant to reduce a peak power load, there are some restriction on deriving a voluntary participation of demand side resource. So it needs a new approach to direct load control method, and this paper describes an advanced load control method using control logic which is based on load properties. This method is easy to take account of a various characteristic of load, it can be use as a dynamic control logic which is good for adaptive control. The suggested control logic method is verified by modeling a control logic for a turbo refrigerator which affects on peak power in summer season.

This study was undertaken to determine the degree of quality of life, and factors influencing osteoarthritis in hypertensive elderly 65 years or older patients, using data from the 7th National Health and Nutrition Survey 2018. Totally, 843 subjects were included from a national sample. The SPSS WIN 26.0 program was used to analyze complex samples by applying the Rao-Scott chi-square test, t-test, and multiple regression analysis. Results indicate that quality of life of the hypertensive group with osteoarthritis is significantly lower than the group with only hypertension (t=5.07, p<0.001). Factors affecting the decrease in quality of life of the hypertensive group were age, subjective health status, and activity restrictions, and the explanatory power was 46.1% (F=12.33, p<0.001). In the hypertensive group with osteoarthritis, the effective factors included gender, cohabitation status, economic activity, subjective health status, activity restriction, body mass index, sleep time, stress perception, and depression, and the explanatory power was 44.6% (F=99.82, p<0.001). Subsequent studies showed that in order to improve the quality of life of hypertensive seniors, intervention programs are required to actively accommodate health conditions and minimize activity restrictions. In addition, for the elderly with osteoarthritis and hypertension, it is necessary to include exercise and nutrition education for body mass index management, and the development and intervention of multidisciplinary participation programs to strengthen mental health.
