This paper examines the interplay among changes in socioeconomic conditions, population policies, and fertility decline during $1960{\sim}2000$ in South Korea. Period-parity-progression-ratios (PPPR) are calculated using 2% samples of Population Census with the implied distribution of completed family size. The total fertility rate based on PPPR declined from 5.21 in 1960 to 2.76 in 1980, and 1.69 in 2000. The family planning programs were successful in meeting the needs of families that wanted to prevent further childbearing after having achieved the desired family size during $1960{\sim}1970$. The 1980s mark two important landmarks: achievement of replacement fertility and emergence of high sex ratio at birth. In the 1990s the "quality and welfare" approach was emphasized. In 2000s, South Korea's fertility is one of the lowest in the world. In response to this, in 2005, the Government adopted a new population policy with the goal of increasing the total fertility level to 1.6 by 2010. The results of this study indicate that proportion of women who would have no children at all throughout their reproductive life span increased substantially from 10% in 1995 to 16% in 2000, with a sharp increase since 1997. Thus, pro-natal programs need to address the problems associated with marriage and having the first child. Towards that, it is important that work and family life become more compatible.

Objective: This study aimed to report the level of extremely low frequency-magnetic field (ELF-MF) emitted by portable hand-held fans (HHF) and to discuss the methodologies for determining the health risk of ELF-MF for HHF products. Method: ELF-MF was monitored at eight locations by distances in the vicinity of HHFs. A total of 13 HHF brands on the market were randomly selected. A portable ELF-MF monitor MDEX II was used to measure the ELF-MF level in the range of 40-800 Hz with a resolution of $0.01{\mu}T$. This study also examined the frequency results of a total of 45 HHF products investigated by the Korean Ministry of Science and ICT (KMSICT). Results: ELF-MF higher than $0.3{\mu}T$ was found to be emitted at a distance of less than 20 cm from 12 HHF. ELF-MF emitted from four products was found to exceed the reference level ($83.3{\mu}T$ based on 60 Hz) recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). KMSIT reported that the principle frequency emitted from the HHFs ranged from 54 Hz to 284 kHz, without the level of LEF-MF. Unscientifically, the KMSICT used the reference level by ICNIRP as the chronic level and concluded that all HHFs are safe with a basis of 1.2-36.0% less than the reference level. Conclusion: The HHF emitted much higher levels of ELF-MF than $0.3-0.4{\mu}T$, which is regarded as the reference level for childhood leukemia. The risk of HHF should be examined in terms of whether they can be used by the general public, including children and pregnant woman.

This study was conducted to abbess dietary intake and eating habits of low-income persons aged 60 years or elder. 212 persons were surveyed between July 10 and August 17, 1978 ; 105 from the farming village of Yang-ju, Kyunggi province; and 107 from Karakdong, an area of redevlopment in the suburbs of Seoul. Results were as follows : 1 ) Family environment 84% of elderly persons surveyed, lived with their children; 13.2%, together as a couple; and 1.9%, widowed, lived alone. More than half on the households had an average monthly income of \50,000 to \30,000. The average Engel index was 61.2%. As for pocket money, 56.4% of male subjects had \l,000 to \7,000 per month, whereas 74% of female had less than \1,000. 2) Anthropometric measurements 59.9% of subjects were $70{\sim}90%$ of standard weight, 93% had an arm circumference only $60{\sim}80%$ of the standard. 3) Food and nutrient intake Carbohydrate provided 73.4 to 79.4% of total energy intake, whereas protein and fat accounted for 10.4 to 10.5% and 8.3 to 7.8%, respectively. Those over 65 years of age showed a somewhat greater dependence on carbohydrates for energy, than those under 65. Protein intake was only $42{\sim}52%$ of the recommended allowance. and the proportion of animal protein to total protein was only $2.1{\sim}9.3%$ far below the recommended allowance. Thus the protein nutrition of the subjects was proven to be inadequate qualitatively as well as quantitatively. Intake of energy and of all nutrients except vitamin A and ascorbic acid, were lower than recommended. 4) Correlational assessment The correlation coefficient between poor dental health, clinical sign score, appetite index, dietary balance and nutrient intake, was significant (0<0.01). Poor teeth, illness, and poor appetite were always associated with inadequate intake of energy and nutrients. The results of this survey reveal that many of elderly of the rural and urban poor show evidence of general malnutrition, The authours hope that this study will provide a back. ground and indicate the direction that community health and welfare programs may take to assure proper nutrition for the elderly.

With the rapid progress of the aging society in Korea, the silver generation is emerging as another class of users in the new population structure. This is a social issue to be dealt with, and the effect of such a change is being observed dearly in the design area. In addition, there are increasing demands for consideration of minor groups of users including the elderly, the disabled, the left-handed, children and pregnant women and nursing mothers, who have been treated as the weak. Such a human-centered idea may be the manifestation of the recovery of humanity and the self-realization of human beings through experiences and reflections of the industrial society of the past. The present study examined the tendency of design standardization centering on universal design, which has emerged in response to user-centered social needs, and suggested general considerations for the necessity of introducing such standards. These days the meanings of standardization are not limited to quality, performance, safety and economic aspect. Standardization is required to consider the diversity and the welfare of human beings. In addition, one of the important functions of standardization is to provide designers with important clues and guidelines for designing. In reality, however, standardization has been rejected by the circle of design for the reason that it deters free creation, so research on the introduction of standardization has been at standstill. As ISO/IEC Guide71 was published in November 2001, based on which, the Korea Standards Association established KS A ISO/IEC Guide71 without changing its contents. In companies' manufacturing activities, the progress of standardization in connection to universal design is growing more important. However, usefulness and interchangeability for the absolute majority resulting from standardization are incomparable. Lastly, the realization of universal design requires human-centered design mind, based on users' experiences and needs, the characteristics of the human bodies and inconvenient elements rather than standards for the sake of standardization.

Purpose:Epilepsy of child may cause high level of psychosocial difficulties for parents including stigmatization and stress and therefore worsen their quality of life (QOL). The purpose of this study was to evaluate the mediating effect of perceived stigma against epilepsy on QOL among parents with epileptic child. Methods:Two hundred and sixty parents of epileptic child recruited from five separated university hospital child neurology clinics specializing in epilepsy completed a demographic questionnaire, a medical questionnaire, a perceived stigma questionnaire and the Ro's Quality of Life Inventory, a popular tool for evaluating QOL of adults in Korea which is composed of 6 domains and 47 questions. Data was analyzed with SPSS 14.0 program using frequency analysis and descriptive analysis and with AMOS 7.0 program using Structural Equation Model (SEM) analysis. Results:The level of parents' QOL was relatively fair. SEM analysis on the quality of life level of parents showed that all variables (especially having religion, the monthly income, employment state, age of child, the leisure time, the perceived stigma level against epilepsy, and seizure frequency) directly affect the quality of life level of parents and that disease-related variables also affect the quality of life level of parents indirectly through the mediating factor (the perceived stigma), where the indirect effect is large with the existence of combined disabilities. The total effect on the quality of life level of parents is large with the existence of combined disabilities, the perceived stigma level, the leisure time, having religion, and the monthly income. Conclusion:The results of this study indicated that many factors including parents' perceived stigma may affect the quality of life of parents with epileptic children directly, and that some disease-related factors may affect indirectly through a mediating factor, the perceived stigma. Multidisciplinary collaboration would be imperative for their welfare.

This study aims to investigate both general dietary behaviors and clinical symptoms of diet related effects among fifth grade students at an elementary school in Ulsan Metropolitan City, and to categorize those relationships in terms of their comparative differences. The findings of this study are as follows. 1. Out of 694 students polled, 53.7% were of boys and 46.2% were girls with average age of $11.9{\pm}0.3$, average height of $145.1{\pm}6.8cm$, and average weight of $39.7{\pm}9.7kg$. Obesity in boys (5.5%) exceeded girls (3.9%) whereas children categorized as underweight showed girls (14.6%) slightly exceeded boys (10.4%). 2. Dietary behaviors were largely the result of four factors - unbalanced diet, balanced diet, protein and fruits and healthy dietary habits. Of these factors, protein and fruits ($4.04{\pm}1.03$) ranked first, balanced diet ($3.38{\pm}1.04$) second, healthy dietary habits ($3.04{\pm}1.01$) third and unbalanced diet ($2.23{\pm}0.6$) ranked last. 3. When Dietary behaviors were classified with four low ranking factors, they were divided into four types such as convenience (22.4%), good diet (24.7%), busy contemporary modern man (24.3%) and healthy dietary habits (26%). 4. Clinical symptoms include colds ($2.27{\pm}1.15$) followed by headaches ($2.17{\pm}1.19$), stomachaches ($2.16{\pm}1.15$), dizziness ($2.02{\pm}1.15$), atopic allergy ($1.95{\pm}1.30$), prevalence for cold sores ($1.86{\pm}1.07$), allergy ($1.65{\pm}1.05$), and constipation ($1.54{\pm}0.87$). 5. According to the results, clinical symptoms were divided into two groups - unhealthy (40.1%) and healthy (59.9%). 6. By analyzing the relationship between dietary behavior types and clinical symptom types, the convenience factor included slightly more of the unhealthy group (56.3%), whereas the good diet (71.1%), busy contemporary modern person (55.8%) and healthy dietary habits (69.7%) included more of healthy group (p<.001). Since the majority of students belonging to the unhealthy group had convenience dietary behavior, education about desirable dietary activities is needed for these students. In addition, nutrition information and information on possible clinical symptoms caused by nutritional imbalance should be provided for students and their households.

Through our entire life, oral care products such as toothpaste are used. Thus the safety of oral care products used every day to our mouth is very important. As the previous study in animal tests or clinical trials, surfactant in toothpaste may cause the oral irritation. However, EU cosmetics legislation prohibits animal testing of cosmetics and its ingredient for animal welfare. Therefore the development of alternative in vitro test has been actively performed to replace or reduce using the animal in many areas. However, the way to evaluate oral mucosal toxicity has been done using animal models or clinical trials from now on. Even more, the experiment with human oral 3D tissue or human oral cell line is used recently. The aim of this study is the development of oral mucosal irritation method without using animal for the safety of the oral care product. We developed in vitro test method for oral irritation by using human oral cell line (YD-38 cell) acceptable to toothpaste which contains insoluble material. By the results of this assay, we could discriminate toothpaste with or without irritating substance as same manner in animal studies reported previously. In addition, we confirmed that toothpaste for babies and children toothpaste irritated oral musoca lower than the general adult toothpaste. The present study suggest that this new in vitro method by using human oral cell line (YD-38 cell) could be used for evaluation of oral irritation without using animal.

In the present, since a five-year plan for economic development which was started in the early 60's has been successfully promoted for a quarter century, with consolidation in a department of social welfare in our country the participation. in economic society for women is more required than any other times. As a professional occupation for women is incereaing through a high-standard specialization, I think the upbringing for productive woman expert who has a strong motive of accomplishment as a developed person as well as a technical and skilful capacity which can be contributed to the growth of organization is very important. So in this study, I am evaluating the technical disposition of character of professional nurses working with hospital and also trying to supply the basic data being served to th extension of a skillful ability as a nurse, understanding the important factor related to it. The research method applied here is that we used 527 of formed questionnaires which were distributed to 7 University and General Hospitals, somewhat large in a scale, located in Seoul as an analytical material. It was performed between October 11, 1988 and October 18, 1988. An implement which was invented by Cho Moo-Sung is used after being amended and supplemented, which can measure the disposition of professional character. The formation of questionnaires of the disposition of character is 26 totally, 10 for Open-disposition, 11 for Active-disposition, 5 for wise-disposition, and it was measured. 'Ye', or 'No' through an one-half-standard and the environment of hospital organization is composed 12 questions from one point of 'Very Good' to 5 points of 'Very Bad.' Collected materials were analysed through an electronic calculation into the average value, the standard deflection, percentage, person correlative number, $X^2-test, m$ stepwise multiple regression. Summarizing the result from this research is as follows; 1. The average age of the subjective person of this investigation is 28.6 and the average career as a nurse is 6.0 years. 2. The Open-disposition that technical nurses showed is mostly half and half. 3. The Active-disposition of professional nurses was discovered affirmative largely and what they said in their questionnaires describes that they are very active answering $88.2\%$ for the disposition of self-control, $87.3\%$ for the people who think the training more seriously. 4. It was found out that the wise·disposition of technical nurse showed $90.7\%$ of 'Yes' about a new alternative of inquisitive question and we can see a progressive and profound aspect here. 5. As technical character of nurses, mutual relations between Active-disposition, Active-disposition, and wise­disposition were very profitably revealed as 0.42 in justice relations and also suggested that relations between Open-disposition, Active-disposition, and wise-disposition are 0.27 and 0.20 respectively. 6. What nurses recognize about the environment of hospital organization is reasonably acceptable while they feel very bad about rewards and punishments showing average 3.1 comparing to average 2.2 about time­control each other. Considering the prosperity of Active-disposition upon the result what I mentioned above, th possibility which is contributed to the productive improvement of hospital organization is very great and I think it can be more developed as a professional woman who has a strong motive of accomplishment, in advance.

The current employment status among young home economists and perspectives in occupations for prospective Home Economics graduates were explored in this study which utilized information from 17 to 21 colleges in Korea and colleges in the United States during the five years of 1977∼1981. The Home Economics content areas covered in this study were Clothing and Textiles, Foods and Nutrition, Housing and Interior Design, and Child Development and Family Life. The highest percentage of Korean graduates in Clothing and Textiles was employed either as teachers at the junior high school level or as designers in the clothing and textile industries. Quite a number of the graduates were engaged in further studies at the graduate level. Korean graduates with a master's degree were teaching at the college level and some had furthered their studies at the doctorate level either here or abroad. Koreans with a bachelor's degree in Foods and Nutrition held jobs as teachers in junior high school, dieticians at mass feeding institutions and hospitals, food scientists in food industries, and researchers in institutions. Those with a master's degree were teaching at the college level. Americans with a bachelor's degree worked as dieticians, supervisors in restaurants and institutions, extension workers, researchers at various facilities, teachers and clerks. Americans with a master's or doctorate degree were engaged in teaching at colleges or supervising at research or working as extension specialists. In general, Korean graduates were found to hold positions in less varied areas than their American counter-parts. Among forty-nine graduates those working in their professional field reported less sex discrimination that those working in other fields. The major area of employment in Housing and Interior Design or Home Management graduates in Korea was teaching while in the United States it was extension work, business, governmental work and teaching. It was suggested that in the future, career development in Korea be further explored to include extension service, research, social welfare, financial planning, business, free-lancing, funeral home, home-call, and correctional education. Interviews with executives from 6 business enterprises indicated that most of them were aware of the potential contribution home economists could make for their companies but they expressed a negative attitude towards women in general due to their short stay on the job. Jobs held by Child Development and Family Life majors with a bachelor's degree in Korea were mostly teaching positions in public, junior and senior high school. However, jobs such as nursery school teaching, working in clinical setting, business, and teaching at public, junior and senior high school predominated in the United states. Most Korean graduates with a master's degree were teaching in professional colleges while in the United Stated the job variation among the graduates was rather evenly distributed among teaching at college level, public and high school, nursery school and administration areas. Reports from 7 child development majors on the job indicated that they were paid less that secretarial workers. Only half of them were working in their major area and these expressed satisfaction with their work. Two thirds of the respondents indicated no sex discrimination. It was suggested that in the future Child Development and Family Life majors pursue employment in counseling, guidance, recreation, mass media, administration and outreach work as well as education, research and parent education in services for children, teen-agers, adults and families.

American Psychiatric Association defined hwa-byung as a unique mental illness of Korea, a kind of anger syndrome. This illness caused by the Korean culture is more often found on women than men, especially middle-aged women. The cause of hwa-byung mainly depends on the traditional family structure of Korea formed by Confucianism. Other causes that many middle-aged women suffer from hwa-byung are that their low education level originated in their wrong-recognized position in society and poverty in the past makes them not to be able to control their minds effectively(social psychological factor), and that they get stressed and depressed because of loss of their position in the family after their children leave home and the menopause which hurts their feminine beauty (physiological factor). So, this program aims at letting them to; 1) experience catharsis of the negative feelings which causes hwa-byung by expressing in psychodrama, 2) ease the symptoms of hwa-byung by relaxing their mind, 3) understand themselves through sharing their feelings and thinking at the group level, 4) acquire the opportunities to stabilize and expand their role in their real lives through the role playing.
