To show the recognition of hand-sanitizer, we studied the answers of research questions where we got from the northern part of Seoul and Kyunggi Province. We had categorized two groups both industry-related people who work in restaurants, hygiene service shops, whole sales, government organizations, PC shops, factory-department stores and non industry-related people who work in schools, general offices for this study. 1. Hand sanitation level: Over 60% people washed hands 6 times a day. The group using water and soap was much bigger than the group using water for washing hands. For drying, people preferred wipe tissue, towels, clothes, non drying in that order. 2. Recognition of hand sanitizer and its usage experience: Most people(66.5%) did not know what hand sanitizer is, but they have positive attitude if they use this machine. 3. Place of hand sanitizer: The proper places to install were such public places as hospitals, restrooms, and restaurants. The fifties-group was the most frequently hand washing generation with over 9 times a day. 4. Comparison of recognition for hand-sanitizer by male and female: There were different results in each evaluation item by either male or female. The frequency and method of hand washing showed high in males, while females observed hand sanitization, installation requirements, installation areas, home installation, etc more than anything else.

Purpose: To investigate the prevalence of smoking behavior among elementary students which may serve as basic data for developing a smoking prevention program. Method: Questionnaires were given to 734 fourth, fifth, and sixth graders in five elementary schools in U county, North Chungcheong Province. Data were collected from 8 to 20 December, 2003; and analyzed using SPSS/PC for descriptive and chi-square statistics. Result: Of these students, 19.9％ reported that they had smoked and 0.8％ answered they are current smokers. They reported that the first smoking started during third grade (26.0％), at their homes (38.4％), and out of curiosity (74.0％). They reported severe coughing when they first smoked (56.2％). Smoking experiences were significantly related to grade, gender, and academic performance. Similarly, environmental characteristics such as residential area, parental status, father's job, parental attention, home atmosphere, and smoking siblings or friends were significantly related to smoking behavior. Among non-smokers, 86.4％ intended not to smoke and 1.4％ would like to smoke in the future. Conclusion: Certain school and environmental characteristics were associated with smoking experimentation. Therefore teachers and parents should use this information to develop and guide smoking prevention programs.

Recently elderly has been recognized as a healthy and active generation because of extended average life span by medical development, interests in health, and achieved economic power while elderly was regarded as a passive and dependant generation before. The primary purpose of this study was to analyze the lifestyle types and housing consciousness of the middle ages around fifty's who will have more inclinations in the future to consider the hosing problems of elderly. To collect the data, LOV survey method was used for 600 middle ages about their lifestyles and future housing types. The data analysis used SPSS PC 12.0 to find the frequency, chi-square, factor analysis, and cluster analysis. The results of analysis are as follows: First, the lifestyle was segmented into five groups and there were differences on demographics such as education and income, also on housing sizes and types of home-ownership types. Second, there were different preferences on the types of senior housing by different lifestyles whereas there were similar on the location and sizes of houses by different clusters.

The paper is to solve the problem of existing audio signal transfer system which has a difficulties of system organization and the increase of additional install cost and unfriendly interior. To solve the existing system, we drew the new audio signal transfer system based on PLC and evaluated it. A transmitter and a receiver were designed using the PLC chip INT5500CS. An audio signal transfer system was configured with a CD player to which audio signals are sent from the transmitter and a speaker connected to the receiver. For performance evaluation of this system, a USBPre external sound card and Smaart Live 5 which is a PC-based sound measuring program were added. As a result of our experiment, the measured signal level is $2{\sim}3$ dB lower than reference signal, latency is 16.69 ms, and the specific character of coherency is bad in high frequency band. Otherwise, this system transmits and receives signals over 90 % in good condition as a result of measuring pink noise, frequency (1 kHz), and phase, magnitude. In view of the result so far achieved, the system designed this study has excellent performance, it resolves defect of existing audio signal transfer system.

This paper presents objective methods which predict perceptual noise levels caused by refrigerators. Eight home refrigerators are chosen and their noises are recorded in an anechoic-chamber and a real-life apartment. In order to obtain perceptual noise levels of the refrigerators, subjective quality assessment tests were performed by 100 evaluators Then, we compute 5 sound quality metrics (SQM) which reflect psychoacoustics characteristics. Finally, objective assessment model for refrigerator noises is developed by linear combination of SQMs.

Purpose: The purpose of this research was to examine the degree of care stress and the quality of life of grandmothers caring for their grandchildren while mother was employed. Method: A convenience sample of 107 grandmothers were measured for grandmother's care stress using a revised for of the PSI/SF and the quality of life tool by Andrew and Weinert. Descriptive statistics, t-test, and Pearson correlation coeffcients were used to analyze the data using SPSS/PC 10.0 Results: The results found that grandmothers' care stress was high according to their age and religion. Their quality of life was low according to their age, their present health status, income and sleep pattern. Their subjective care stress was a sense of social isolation, burden of caring for grandchildren, health problems, and conflict with adult children. Care stress and quality of life were found to be negatively correlated. This result was statistically significant. Conclusion: In conclusion, it was found that the care stress was high and affected quality of life. From this study it is proposed that there is a need to develop programs which consider grandmother' techniques in child care and health care to improve their quality of life. Ultimately, a good care environment for children will be good for the children's growth and development.

The data were obtained by administering a self-reported questionnaire to high students adolescents residing in Seoul and Gyeonggi. A total of 316 questionnaires were used as the final data for this study. Statistical analyses were carried out using SPSS/PC. The main results of the study are as follows: First, the adolescent's self-leadership greatly influenced the student's manners. Second, the relationship between self-leadership, manners and the adjustment to school life showed a significantly positive correlation. Third, a stepwise regression analysis showed that self-leadership competency and implementation of manners made a comparatively high contribution to the adolescents' adjustment to school life. Therefore, the degree of the student's self-leadership and use of manners in order to maintain harmonious relationships with others leads to a healthy and happy scholastic life for the student.
