This study was conducted in order to find out the attitude of housewives toward the home attendants system, the type of institute managing home attendants, the education for home attendants, the basic requisites for home attendants, and home nursing education, and identify the factors influencing on the housewives's attitude. The data were collected through questionnaires obtained from 401 housewives from March 1 to March 31, 1988. The results summarized were as follows; 1) 90.2 percent of total housewives favored the home attendants system, and housewives who had have their family member with health problem especially showed favorable response. 2) The favored types of institution managing home attendants appeared to be private social work agency(33.0%), half-private and half-public agency(32.2%), government agency(19.9%) and profit agency (2.2%). In particular, housewives who had experienced nursing favored half-private and half-public ageney (37.6%). 3) As the basic requisites for home attendants, housewives wanted service attitude(37.2%), nursing education(34.4%) and nursing experience(28.4%). But, housewives with nursing experience favored nursing education rather than service attitude. 4) 91.1% of total housewives favored the home nursing education. In particular, housewives of high education level and nursing experience showed more favorable response to the home nursing education.

This study explored a typology (or time allocation), investigated personal and work characteristic differences among time allocation types, and identified determinants of time allocation types of married working women with a preschool child. The data source for this research was the 2014 Time Use Survey conducted by Statistics Korea. We analyzed 368 time diaries (184 for weekdays and 184 for weekends) using frequency, mean, cluster analysis, chisquare, analysis of variance (ANOVA), Duncan's test, and multinomial logistic analysis. The results of this research are as follows. Time allocation of married working women with a preschool child was classified into three different types of 'work-centered,' 'work-family balanced,' and 'family-centered.' The work-centered type accounted for 14.7% of total respondents, and compared with other types, this type of people spent more time working, and less time doing house-work, caring for family, and having leisure. The work-family balanced type represents more than half of the total, and spend more time working on weekdays and house-working, having leisure on weekends. The family-centered type represents 28.8%, and spends most of the time doing house-work and caring for family on both weekdays and weekends. Occupation, employment status, monthly income, and weekly hours of work were different for each type. Occupation, employment status, perception of lack of time, health condition, and weekly hours of work were identified as determinants for each type.

Purpose: The purpose of this study was to identify the psychosocial working environment and mental health of financial workers, and analyze the impact of the former on the latter. Methods: Data of 257 financial clerks were extracted from the 2017 5th Korean Working Conditions Survey. Psychosocial working environment was divided into five fields: demands at work, work organizations, interpersonal relations, workplace violence, and working hour quality. Mental health included sleeping problems, psychological well-being, and job stress. Results: A total of 6.1% subjects reported sleep problems, 28.2% experienced poor psychological well-being, and 39.6% had job stress. More than half the subjects were exposed to tight deadlines, complex tasks, hiding feelings at work, fair treatment, fair distribution of work, colleagues' support, and managers' support. Tight deadlines, workplace violence, long working hours, hiding feelings at work, and managers' support had a significant impact on the mental health of financial clerks. Conclusion: Based on the results of this study, we propose that employers, workers, and health managers in the financial industry should work together to establish a respectful organizational culture, prevent long working hours through recruitment, and conduct programs to protect emotional health.

The purpose of this study was to investigate the human body effect according to micro bubble and LED lighting in half body bathing. This study was conducted on 6 elderly male and 7 female in 70's, and the subjects were classified into half body bathing with the micro bubble group (3 male, 4 female) and without the micro bubble group (3 male, 3 female) to proceed to the experiment. Experiments were performed 4 times by changing the LED lighting colors. As a result, parasympathetic nerves were activated than sympathetic nerves (micro bubble stimulation : 21.41%) and the temperature of the body were increased by $5.93^{\circ}C$ with micro bubble and red lighting stimulation. It is considered that this work will help to utilize the half body bathing system for the micro bubble and LED lighting.

This paper is concerned with an analysis of a surface edge crack emanated from a sharp contact edge. For a geometrical model, a square wedge is in contact with a half plane whose materials are identical, and a surface perpendicular crack initiated from the contact edge exists in the half plane. To analyze this crack problem, it is necessary to evaluate the stress field on the crack line which are induced by the contact tractions and pseudo-dislocations that simulate the crack, using the Bueckner principle. In this Part I, the stress filed in the half plane due to the contact is re-summarized using an asymptotic analysis method, which has been published before by the author. Further focus is given to the stress field in the half plane due to a pseudo-edge dislocation, which will provide a stress solution due to a crack (i.e. a continuous distribution of edge dislocations) later, using the Burgers vector. Essential result of the present work is the corrective functions which modify the stress field of an infinite domain to apply for the present one which has free surfaces, and thus the infiniteness is no longer preserved. Numerical methods and coordinate normalization are used, which was developed for an edge crack problem, using the Gauss-Jacobi integration formula. The convergence of the corrective functions are investigated here. Features of the corrective functions and their application to a crack problem will be given in Part II.

The purpose of this research was to find out attitudes toward work and leisure in later life and intention to move to senior community available to work among 50's in Pusan, Daegu, and Daejeon. The survey had been conducted in 414 respondents with questionnaire during May to June, 2003. Frequency, Crosstabs, T-test and ANOVA were obtained from the collected data using SPSS/WIN program. The results of this study were as follows. First, most respondents were preparing toward work in later life somewhat actively and the level of preparation differed by individual characteristics. Those who have higher level of education and subjective economic power were more active. The most preferred work item in later life were raising animals and plants, managing institution and training center and running shop. Those who have higher level of education and asset preferred managing institution and training center. Second, nearly three fourths of middle-aged have chosen leisure activities in consideration of later life and two thirds were preparing economically for leisure in later life. They have strong intention to participate in the leisure activity in later life and they also wanted to take part in various kinds of leisure activities. Those who have higher levels of education, subjective economic power, health and asset were more active in preparing leisure in later life. Third, over two thirds preferred to live and work in later life together with others rather than to live and work alone. Nearly half had intention to move to the senior community where work was available. The intention to move were differed by attitudes to work and leisure in later life. Those who were active in work and leisure in later life presented higher intention to move to senior community available work.

The purposes of this study were to identify the needs for the employer-supported day care service and to analyze the factors related to the needs for the day care service of the married employees. KLFI(1995)'s National data were used and three Logistic models and one Catmod model were employed to analyse the effects of the independent variables on the needs for the day care service. The results of this study were as follows: First, half of employed workers needed the employer-supported child care service. Second, they preferred the day care center near their residential area than in their work site. Third, according to their age, type of occupation, and their difficulties for the childcare and household work, employed men and women needs on site day care differently. Finally, their needs for the expenditure of duty care service differed by their age, sex, and occupation, and their levels of difficulties for the childcare and household work. These findings suggest that duty care service for the employed man and woman are supported diversely according to their needs and preferences.

In construction sites, small-scale construction quantities or limited work hours below the daily work volume may occur due to on-site conditions. For small-scale quantities, the input of equipment and labor is designed based on an hourly basis in the invoice, resulting in a difference from the actual cost. In this study, we aim to explore solutions from the perspective of construction cost standards to secure appropriate construction costs for small-scale and time-limited construction sites. Firstly, to preserve the basic construction costs on-site, we established standards where half the cost would be charged for construction quantities below four hours and a full day's cost would be designed for construction quantities between four to eight hours. Additionally, realistic construction cost calculation standards are expected to be provided by realizing a surcharge rate for work hour limitations to secure appropriate construction costs.

The purpose of this study is to examine the change of full width half maximum(FWHM) and residual stress during fatigue process in S45C Steel, by X-ray diffraction. For S45C Steel, the relationship between the change in fatigue damage of the specimen and the FWHM, and residual stress of X-ray diffraction profiles during the fatigue processes has been investigated. The FWHM decreases in the early period of fatigue cycle. The change of FWHM is associated with cyclic work hardening. The change of the FWHM is not significant in $10{\sim}20%$ of ratio of fatigue life. The residual stress is changed with fatigue cycle increasing during the fatigue pro process.
