The main purpose of the study was to clarify the properties of individual particles collected at each behavior space of a factory worker. The samplings of size-segregated ($PM_{2.1-1.1}$ and $PM_{4.7-3.3}$) indoor particles were conducted at three different behavior spaces of a factory worker who is engaged in an auto parts manufacturing plant (i.e., his home, his work place in factory, and his favorite restaurant). Elemental specification (i.e., relative elemental content and distribution in and/or on individual particles) was performed by a micro-PIXE system. Every element detected from the coarse particulate matters of home was classified into three groups, i.e., a group of high net-counts (Na, Al, and Si), a group of intermediate net-counts (Mg, S, Cl, K, and Ca), and a group of minor trace elements (P, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, and Pb). The results of EF for $PM_{4.7-3.3}$ in home indicated that several heavy metals were generated from the sources within the house itself. An exceptional feature shown in the individual particles in workplace is that Cr, Mn, and Co were clearly detected in both fine and coarse particles. Cluster analysis suggested that the individual coarse particles ($PM_{4.7-3.3}$) collected at the indoor of factory were chemically heterogeneous and they modified with sea-salt, mineral, and artificially derived elements. The principal components in individual coarse particles collected at restaurant were sea-salt and mineral without mixing with harmful trace elements like chromium and manganese. Compared to the indoor fine particles of home and restaurant, many elements, especially, Cl, Na, Cr, Mn, Pb, and Zn showed overwhelmingly high net-counts in those of factory.

In order to find out perception of group home for the people with disabilities worker on sexual behavior of adults with developmental disabilities in a holistic way, This study conducted in-depth interviews with six research participants using Giorgi's phenomenological study method to understand the meaning of perception of sexual behavior of adults with developmental disabilities. According to data analysis, these experiences appeared as two thematic themes: 'sexual trouble behavior' and 'perception of sexuality'. Two sub-themes of 'Excessive expression of sexual desire', 'Improper sexual behavior that can lead to sexual offenses' were derived from the essence theme of 'sexually problematic behavior' and 'perception of sexuality' were derived from the essence theme of 'lack of suitable solution', 'conditions that are not enough to have sex appeal', 'frustrated sexuality', 'some dilemma problem', 'sexuality that is not different from non-disabled', and 'love and sex are ok, pregnancy and marriage are no'. Based on this, group home caregivers contribute to their role as the main agents who reinforce and reproduce the sexual norms of adults with intellectual disabilities, while at the same time they experience confusion in their values about sexual norms of people with intellectual disabilities. Based on the results, We discusses the major intervention plan for education programs to enhance the competences of group home caregivers in order to form a holistic perspective of group home caregivers in sexuality of people with intellectual disabilities, and provide rational solutions.

This study examined the effects of household head’s worker status change type on household income and household head’s income using a total combined sample of 2,578 households from Korea surveyed in 1998 and 2002 KLIPS(Korean Labor and Income Panel Study). Binary logit regression results showed that household incomes were likely to decrease significantly when household head’s changed worker status from a regular employee, a temporary employee or a daily worker, or an employer or a self-employed to no job status, or from a regular employee to a temporary employee or a daily worker, an employer or a self-employed, or from an employer or a self-employed to a regular employee compared to a regular employee status maintenance. In contrast, household head’s incomes were likely to increase significantly when household head’s changed worker status from a temporary to a regular employee compared to a regular employee status maintenance. Women household heads were significantly associated with the likelihood of the decrease of household head’s income compared to men household heads. Household heads beyond their forties were significantly associated with the likelihood of the decrease of household head’s income compared to household heads in their thirties age-group counterparts. Household heads with education level beyond high school graduation were significantly associated with the likelihood of the increase of household head’s income compared to household heads with the education level of high school graduation. This study shows that a more comprehesive labor policy is needed for achieving sustainable household income inflow.

The purpose of this study was to understand the effect of job stress of female caregivers working in home-based elderly welfare centers on turnover intentions and to understand the moderating effect of self-elasticity in these relationships. The subject of the study was a self-written questionnaire survey of 170 nursing care workers at 28 home-based elderly welfare centers in Seoul, and 150 copies were collected and 133 people were finally analyzed excluding 17 unscrupulous responses. As a result of the study, first, the average value of turnover intention was high in the group with low experience of female caregivers at home-based elderly welfare centers and the group without religion. Second, the higher the job stress of nursing care workers, the higher the intention of turnover. Third, there was a moderating effect of self-elasticity between the job stress and the of turnover of nursing care workers. Therefore, it was necessary to consider measures to prevent job stress of nursing caregivers and improve self-resilience.

In this study we examined the greenhouse worker's work load to test the efficiency of the developed vehicles (hand operated vehicle (HV), simple battery-powered autonomous vehicle (AV)). The subject of this study were healthy adult females who had experience in growing crops. We measured workers' heart rate, blood Pressure. rectal temperature, mean skin temperature, oxygen consumption and blood lactate level as a physiological index of work load. The results of this study are as follows : The test group using experimental vehicle showed the lower heart rate (mean$\pm$S.D. for HV, AV respectively 74$\pm$5, 75$\pm$3 beats/min, p＜0.01) than the control group (84$\pm$8beat/min) not using experimental vehicle and the lower systolic blood Pressure (HV, AV respectively 109$\pm$8, 109$\pm$9 mmHg, p＜0.01) than the control group (121$\pm$11 mmHg), and lower rectal temperature(HV, AV respectively 37.0$\pm$0.1, 36.8$\pm$0.2$^{\circ}C$, p＜0.01) than the control group (37.0$\pm$0.2$^{\circ}C$), and the less oxygen consumption (HV, AV respectively 2.13$\pm$0.09, 1.66$\pm$0.52$m\ell$/kg/min, p＜0.01) than the control group(2.43$\pm$0.12$m\ell$/kg/min), and the lower blood lactate level (HV, AV respectively 2.03$\pm$1.00, 1.66$\pm$0.52mmol, p＜0.01) than the control group (2.43$\pm$0.12mmol). Judging from these results, these experimental vehicles for greenhouse workers can be confirmed as a useful tool. It is suggested that these vehicles would alleviate the peasant's syndrome including muscle fatigue and musculoskeletal disease usually caused by working in an uncomfortable posture.

This study was undertaken to investigate protein effects on the adaptation of shift work. Since biorhythms differ according to the time of day, an investigation of the change of metabolism during day-shift and night-shift was undertaken by dividing twenty 3-shift worker into two groups: dormitory diet group and milk & egg supplemented group. Between the two groups, estimations were made on the concentrations of serum protain, albumin, cholesterol and cortisol and the excretion of vanilymandelic acid(VMA), creatinine and nitrogen in urine. The results are summarized as follows: 1. Serum ingredients were gathered from workers at 6:00-7:00h and 14:00-15:00h on the day of their change from morning shift(6:00-14:00h) to night shift(22:00-6:00h). On examnation of the serum ingredient it was found that, in dormitory diet group only the concentrarion level of serum albumin showed a change of rhythm adapted to night work, and in the milk & egg supplemented group the concentration levels of serum protein, albumin and cholesterol all showed a change of rhythm adapted to night work. Serum cortisol of both groups showed the same rhythm as during morining shfits, which implied nonadatation to night work, but the concentration was observed to be lower. 2. Excretion of urinary VMA and nitrogen were higher during night work than during morning work: they were also higher on the 6th day than on the 1st, in comparing the two groups, excretion of VMA was higher among the dormitory diet group, whereas the opposite was ture for excretion of nitrogen among the milk & egg supplemented group. There was no sign of difference in excretion of cretinine among the two experiment groups.

This study was conducted to investigate the weaning practice of 198 infants in Taejon city in October, 1998. Information on infant feeding and weaning practices were obtained by interviewing mothers in gynecologist and pediatric clinics located in Taejon. The results obtained were as follows : In the survey 37.4% of the infants were breast-feeding, while 31.3% of them were bottle-feeding and 29.3% of them were mixed-feeding. The reason for bottled-feeding was due either to the lack of breast-milk secretion or motner’s job. The educational level of the mother and maternal job affected the feeding methods before weaning. Lower rates of breast-feeding were found among mothers witn a lover level of education. The breast-feeding rate was lower in full-time and part-time job worker groups than in housewife. There was no significant difference in the feeding methods according to family income. Among the subjects, 71.5% of infants began to be weaned within 7 months. The onset of weaning was delayed in the full-time worker group. There was no significant difference in the onset time of weaning according to feeding method, the educational level of the mother, and family income. 60.6% of infants received fruit juice and 29.6% of them received cereals for first-given-supplementary food. ‘For baby’s nutritional status’ was the most common motivation for the onset of weaning. Commercially prepared foods were used more than home-made food for supplementary food.

Purpose: This study set out to use a one-group pretest-posttest experimental design to develop a highly motivating CPR program for help care workers who lack CPR education, and to evaluate its effects on their knowledge about program application, attitude, and self-efficacy. Methods: For this purpose, 140 questionnaires were administered to subjects who underwent training at an educational institution for care workers in S city and G province. The program was developed from April, 25 to May, 15 in 2016, and the evaluation period was from May to July, 15. The collected data were analyzed through SPSS version 23, and a paired t-test was conducted. Results: The program spanned 240 minutes, including 80 minutes on theoretical education and 160 minutes on practical education. Knowledge of CPR in the post-test proved to be higher than that in the pre-test, from 6.4 to 9.2 (t=-15.72, p<.001),; the score on attitude increased from 38.4 to 41.7 (t=-5.89, p<.001),; and self-efficacy increased from 41.0 to 66.7 (t=-21.83, p<.001). Conclusion: The basic CPR education program emphasizing motivation was effective for the care worker trainees and could be used for other curriculum by expanding the scope of the subject.
