This study developed functional leggings to guide correct posture for women not trained in the squat exercise technique. Through in-depth interviews, we developed four types of functional leggings that prevent unskilled women from rotating their legs inward or outward, both improper squat forms. These functional leggings include two types of design variables: MD(medial direction design), which turns the lower extremities inward; LD(lateral direction design), which turns the lower extremities outward; and two types of variables according to material. The angles of each part of leggings during the squat movement were measured, and subjective sensations by women were evaluated, including control leggings CD(control design) without rotation function. There was no difference in the adduction and abduction angles depending on the type of functional leggings. However, at the rotation angles of the hip joint (p=0.005), femur (p=0.016), and tibia (p=0.000), the MD leggings rotated inward regardless of the material. Further, the LD leggings rotated outward regardless of the material. The developed functional leggings had an excellent subjective sense of ease of movement, pressure, and preference, thus the developed functional leggings were appropriate while guiding squat posture.

Objectives: We evaluated the physical and mental health problems of waged workers in Korea who had different classes of occupation. Methods: We used data from the Korean National Health and Nutrition Examination Survey (2007-2017) to examine 22,788 workers who were waged employees and categorized these workers into 5 occupational classes. Results: "Unskilled manual workers" were more likely to be older, less educated, have lower monthly income, and work fewer hours per week. Among men and relative to "managers and professionals" (reference group), "skilled manual workers" were more likely to have physician-diagnosed osteoarthritis, "clerks" were less likely to report suicidal ideation, and "unskilled manual workers" were more likely to report suicidal ideation. Among women and relative to "managers and professionals" (reference group), "service and sales workers" and "unskilled manual workers" were more likely to report physician-diagnosed osteoarthritis, depressive feelings, and suicidal ideation. However, hypertension, hyperlipidemia, diabetes, and cardiovascular diseases did not differ among the occupational classes for men and women. Conclusion: We identified differences between men and women and among those in different occupational classes regarding employment status, physical health, and mental health. "Unskilled manual workers" of both genders were more likely to be older, less educated, have less monthly income, work fewer hours per week, and have suicidal ideation. Female "service and sales workers" were more likely to have osteoarthritis, depressive feelings, and suicidal ideation.

We analysed the determinants of part-timer labor demand and supply in Kwangju. The findings of the paper are as follows; First, firms employ part-timer workers in the unskilled or skilled jobs not demanding much training cost. There are two reasons for firms to employ part-time workers: labor cost cut and flexible employment adjustment. Estimated wage differential is 40% not including fringe benefits differential. Second, we find lots of married women to want part-time jobs. The more probably married women choose part-time work, the younger and the less educated they are, and the less kids and the less other income they have.

Purpose: The purpose of this study was to develop a scale to evaluate parenting stress of international marriage immigrant women from Vietnam and the Philippines. Methods: The concept of parenting stress of international marriage immigrant women was analysed with a hybrid model. Data were collected from 273 international marriage immigrant women from Vietnam and the Philippines who were raising their children aged 1 to 6 years. These collected data were subjected to exploratory factor analysis, multitrait/multi-item matrix assessment, Pearson correlation coefficient analysis, and Cronbach's alpha internal consistency measurement. Results: The final instrument consisted of 28 items. The following six factors were extracted by exploratory factor analysis: 'insufficiency of parenting support system', 'role burden of mothers', 'maladjustment of children', 'confusion of parenting methods due to cultural differences', 'unskilled Korean communication', and 'ordinary difficulties'. Construct validity (factor analysis, convergent validity, and discriminant validity) and criterion-related validity were confirmed. Cronbach's ${\alpha}$ value of total items was .92(95% CI .91-.94). Cronbach's ${\alpha}$ of values for these factors ranged from .76 to .85. Conclusion: The parenting stress scale for international marriage immigrant women is a valid and reliable tool.

This study was conducted to help develop women's human resources and promote married women's return to workforce. Using various data, we examined the patterns of Korean women's economic activities over the lifecycle, career discontinuation and return to the workforce. We also interviewed twenty full-time housewives who wanted to return to workforce. The interview questions included reasons for seeking employment, desired working conditions, and difficulties in finding a job. Major findings are as follows: First, there were two groups with respect to reasons why they want employment One was an economic need such as earning basic living expenses and supporting the family. The other was self-realization and social participation. Second most women wanted to do unskilled labor such as housekeeping work, whereas some young or well-educated women looked for a professional job. Third, married women preferred part-time jobs, which were compatible with their family care demands. Most of them wanted a workplace located close to home. The women with child-care responsibility preferred working at home. Fourth, regarding difficulties of returning to workforce, they pointed out vocational ability problems due to their career discontinuation, social prejudice such as gender discrimination and psychological pressure in maintaining work and family at the same time. In order to promote employment of married women, it is required not only to change social prejudices but also to increase effectiveness in policy implementation. In addition, counseling for job-search and vocational ability training programs should be provide.

In the conventional computing environment, users use only a small number of software systems intensively. So it had been enough to check and guarantee the functional correctness and safety of a small number of giant systems in order to protect the user systems and their information inside the systems from outside attacks. However, checking the correctness and safety of giant systems is not enough anymore, since users are using various software systems or web services provided by unskilled developers. To prove or guarantee the safety of software system, a lot of research has been conducted in diverse areas of computer science. We will discuss the on-going approaches for guaranteeing or verifying the safety of software systems in this paper. We also discuss the future research challenge which must be solved with better solutions in the near future.

Koreans are one of the fastest growing immigrant groups in America. Stress responses and stressors among this large cultural minority has been rarely been studied by nursing researchers. Adjusting to life in foreign country produces a great deal of stress. Differences in culture, language, expectations and social behavior can lead to misunderstandings between health care providers and clients. These misunderstandings are not well accounted for in health assessment. This study investigated the relationship between life events or / and daily activities as a stressor and the symptoms of stress among a sample of Korean immigrants in America. The symptoms of stress scale (SOS) was used to identify stress responses and open-ended questions were used to identify life events and daily activities considered by the respondents to be stressful. A simple random sample of 283 subjects was selected from the Directory of the Korean Society of Chicago, New York, Los Angeles, Philadelphia and Seattle. Demographically, the subjects ranged in age from 20 to 69 years, and the percentage of women and men was approximately 50% each. Almost ninety percent of the subjects were highly educated, 17% owners of business, 19% white collar professionals, 14% employed in sales or as skilled /unskilled labor, 27% as housewives and students and 3％ had no occupation. The total group SOS mean was 0.8042 ; the SOS men for man was 0.7371, and for women was 0.8713. The stress response of this subject group was high, -the stress response of women higher than that for men. In an earlier study(June, 1992) with another sample, the total mean SOS score was similar to this one. The main stressful life events or / and daily activities were, in order, economic problems (N=97), interpersonal problems (N=68), children care problems (N=258), health problems (N=49), communication problems (N=42), family problems (N=38), worry about future career (N=36), and religious problems (N=25). There was a significant difference in the SOS means between the group that expressed life events or / and daily activities to be stressful and the group that did not. Interpersonal relationships and economic and family problems were stressors for those who complained about peripheral manifestations. cardiopulmonary symptoms, central-neurological symptoms, gastrointestinal symptoms, muscle ten-sion, habitual patterns, depression, anxiety, emotional irritability and cognitive disorganization. In summary, interpersonal relationships and economic and family problems influenced stress response manifestations. Income, the number of people in the family, the year of immigration. the level of education, and marital status were related to physiological and psychosocial stress responses.

458 female workers working in the small and medium scaled industries in Inchon area were surveyed to study their general characteristics, health behavior, working and environmental conditions, awareness of exposure at hazardous materials, current health status, and degree of working satisfaction. Self-administered questionnaire was distributed to the female workers with the explanation by trained interviewer on the purpose of survey and the method how to answer. The results were as follows : (1) 75.5% of the respondents are living with their families and others are living in domitary or rent house for herself. Age distribution ranges from teenagers to warren in their forties. In marital status 69.0% of workers are single and 31.0% of them have ever married. 69.4% of workers are high school graduate. The size of factory is 48.3% with less than 300 workers, 42.1% with 300~500 workers. (2) Most of the workers(86.7%) are full time workers, 52% of the respondents have working experiences in other factories. More than 65% have fewer than 5 years working experience. (3) The awareness of exposure at noise was 33% of respondents, it was significantly different by skilled status. The awareness of exposure at dust, other hazardous material was each 13.3%, 12.4% of respondents. (4) 26% of them are unsatisfied with their working cognitions and 43.7% of them are unsatisfied with their welfare in occupational system unsatisfactory rate of promotion is higher in the unmarried workers(45.6%), skilled workers(47.2%), full time workers(47.4%), long term workers(50%), and awareness group of exposure hazardous material(51.3%), compared to married women workers, unskilled workers, part-time workers, short term workers and unawareness group of exposure at hazardous materials. (5) The index of working satisfaction is rated on a scale of 1 to 10 with the higher point indicating higher satisfaction. Among the selected variables, marital status, working status, the awareness of exposure at hazardous materials, were statistically significant with the index of working satisfaction. (6) By multiple regression analysis showed that the determinant factors of index of working condition were health index, the awareness of exposure at dust, the awareness of exposure other hazardous materials, marital status and working period. In conclusion, there is a significant relationship between the awareness of exposure at hazardous material the index of working satisfaction. Therefore if the workers are less exposed to the hazardous material and are educated properly they will be more satisfied with their work thus improving their health and productivity. Finally, with the result of this study, there is a great need for the development of a health promotion program and a welfare policy for small-scale factories.
