The World Association for Sexology (WAS) will adopt a Declaration of Sexual Rights as basic and fundamental human rights August this year in Hong Kong. Two years ago WAS has been developing a Declaration of Sexual Rights in order to further promote sexual health and protect the sexual rights of everyone. Undoubtedly sexuality is one of the most intriguing subjects in the area of human behavior and psychology, and has been so since antiquity. The influence of sexual factors of human on all aspects of the society has been immense. The varieties of marriage, from traditional to the open marriage model are presented in front of our sight. The influences of women's movement in Korea, which has produced sexual, psychological, economic, political, familial and social changes look so small and the changes are not that much in America. But the profound effects of the women's movement affect on Korean society being realized as man's view of woman and woman's view of herself undergo constant change and reevaluation. With increased sexual awareness on the part of the public owing to mass media, for example AH-U-SEONG aired in TV and with increased emphasis on sexual matters in daily life, more and more physicians are being asked to deal with and manage sex-related problems in their daily practice. Yet, despite the obvious need for informed sexual counseling, doctors are often uncomfortable about sexual matters and many physicians have no special expertise in this area. So physicians concerned in sexology especially such as gynecologists, urologists, psychiatrists and endocrinologists must realize well about sex-related knowledge which is needed for counseling the patient as medical consumer and gap between reality and ideality in sexual diagnosis and treatment. Establishment of management system for the people who have sexual problems is strongly needed to promote sexual health and protect the sexual rights of everyone and for the Sexual Rights as basic and fundamental human rights.

The widespread pursuit of a thin physique may have a detrimental impact on the wellbeing of preadolescents. The influence of body image distortions on the lifestyles, dieting behaviors, and psychological factors was investigated in 631 fifth and sixth grade children in Kyeonggi-do, Korea. Children were classified into three weight groups (underweight, normal, and overweight) and three perception groups (underestimation, normal, and overestimation). Necessary information was obtained by questionnaire, and each subject's weight status was determined by the Rohrer index calculated from the annual measurement records, which were obtained from the school. According to their current weights, 57.4% of children were normal and 32.2% were overweight or obese, 16.6% of the children overestimated their body weight, and 55.2% had an undistorted body image. Overweight children had desirable lifestyles and dietary habits and presented reasonable weight control behaviors. Compared to those without distortion, the overestimated group had greater interest in weight control ($P$ = 0.003) and dissatisfaction with their body weights ($P$ = 0.011), presented unhealthy reasons to lose weight ($P$ = 0.026), and had higher scores for "feeling sad when comparing own body with others" ($P$ = 0.000) and for "easily getting annoyed and tired" ($P$ = 0.037), even though they had similar obesity indices. More subjects from the overestimation group ($P$ = 0.006) chose drama/movies as their favorite TV programs, suggesting a possible role for the media in body image distortion. These findings suggest that body image distortion can lead preadolescents to develop stress about obesity and unhealthy dieting practices, despite similar obesity indices to those without distorted body images. These results emphasize the importance of having an undistorted body image.

The purpose of this study was to investigate the rural housewives' recognition and practice on environmental preservation. The subjects of this study were 300 rural housewives living in Chung-buk province. Questionaires were distributed to them during a week from August $25^{th}$ to August $31^{th}$ in 1995. Major findings were as follows: 1. The saved water quite well in washing their faces and the dishes compared with urban housewives, but they did not save water so well in using the lavatory. They used synthetic detergent, one of water pollutants, more often than natural soaps in shampooing and laundering. In addition, they did not use a measuring cup. It resulted in the waste of detergent and aggravation of water pollution. 2. Food waste was disposed of properly, but used batteries were not collected separately. A disposable vinyl bag was more commonly used than a reusable shopping basket. The reason for not using a shopping basket was bothering or uncustomary. Since most of them did not know refillable products of goods with environmental mark, they did not use those. Therefore, housewives should be educated in order to prevent soil pollution. 3. The use of spry-type pesticide and hair treatment, one of air pollutants, was wide-spread among them. They hardly recognized and practiced saving of electric power when they used household electric appliances. 4. The major source of environmental knowledge was mass media like TV of radio. Many of them did not know the practical ways to solve the environmental education program. In conclusion, low level of recognition and practice of rural housewives on environmental preservation indicated that a systematic environmental education program should be developed and implemented.

The study was carried out to investigate housewive's consumption pattern and preference of mayonnaise for the development of egg-white mayonnaise. Data was collected from 515 housewives in Ulsan by self-administered questionnaire. The collected data were analyzed by SPSS package program. The results were as follows: 1. Most(98.1%) of housewives were concerned about nutrition and health and they considered that nutrition was the most important factor when purchasing food related items. 2. The frequency of using processed foods was two to three times a week and the reason for use it was the convenience. Usually the housewives obtained nutrition related information through mass media such as TV, radio(37.5%) , and newspaper, magazine(32.1%). 3. 75.9% of the subjects thought mayonnaise is a high calorie food and 57.5% of them knew the basic ingredients of mayonnaise. Most(79.3% ) of housewives perceived that cholesterol which is rich in egg yolk is related to cardiovascular disease and arteriosclerosis. Among family members, children showed high degree in the preference for mayonnaise. 4. Comparison of the low cholesterol mayonnaise which was made by egg white for egg yolk with commercial product was made by sensory evaluation and mechanical test. The viscosity and turbidity did not show any difference. Overall taste of low cholesterol mayonnaise was better than of commercial product. Based on these results of this study provided useful information for development of egg-white mayonnaise (low-cholesterol mayonnaise) and expected the possibility of using low cholesterol mayonnaise will be high.

The purpose of this study is to figure out the urban low-income consumers' present possesion condition of electric appliances, the way of purchasing, shopping scope of groceries and electric appliances, and the shopping scope and information seeking behavior of groceries and electric appliances according to the socioeconomic variables, and the shopping scope of electric appliances according to the way of paying price. For this purpose 129 low-income consumers living in Inchon were interviewed through questionnares. Finally 100 questionnares were analyzed. The first major of this study is that the possesion rates of color television set and refrigerator are comparativelyl high, while those of washing machine, record player and camera are low. In case of electric appliances, consumers usually purchase things on credit and as a shopping place, they usually go to a commercial agent. In case of groceries, they usually buy things for cash, and in case of one price labeled groceries they usually buy things at a supermarket. Second, according to the way of paying price, the shopping scope of some electric appliances is broader in case of purchase for cach than in case of purchase on credit. Third, the shopping scope and information seeking behavior classified by the socioeconomic variables according to the income, age and education. That is as the income and education become higher and the age becomes lower, the shopping scope becomes broader, mass media information source is much more uaed and the frequency of seeking becomes higher. Through this study, I would like to suggest the followings. (1) The problem of low-income consumers is closely connected with the low education level, so it can be solved a bit through consumer education. (2) Especially the consumers' problem is more serious in case of those who are aged and get very low income and education. Therefore special attention is needed to those consumers.

This study explores how the COVID-19 pandemic has changed family life and relationships as well as how these changes affect perceived stress among married men and women. This study investigated changes in family time use, household work, child care, leisure activities, income and expenditures along with relationships between spouses and children using a sample of 627 married persons surveyed online from May 19 to 25, 2020. The results showed that the amount of time spent on household work, child care, and family leisure have increased and that the perceived burden of household work and child care has also increased. Gender differences were found in time use, household work, and child care. Leisure activities have changed toward more time watching TV or online media and playing online games and less time on outdoor activities, shopping, and meeting friends. About 38% of respondents reported a reduction in household income and 22% reported an increase in household debt. The majority experienced no change in the quality of relationships with spouses and children, approximately 20% of the sample reported a positive change in relationships with spouses and children. The findings of multivariate regression indicated that change in work time, negative change in household economy, negative change in household work and negative change in relationships with spouses were associated with marital stress. However, this study found that negative changes in child care and in relationships with children did not affect stress among married parents with children in elementary or secondary school.
