  • The purpose of this study is to identify the impacts of the 5 day workweek system on the family resource management. This family resource may be divided into four spheres (family relationship, household economy, household labor, and leisure activity). Data were obtained from 182 husbands and 182 his wives. He is employed in a company which have fully introduced the 5 day workweek system. Descriptive Statistics(frequency and mean) was used for examining a demographic characteristics and a thought of the system, and t-test analysis for the difference by sex and before and after. According th the results of this study, first, after operation of the 5 day workweek system, the couple have more conversation with each other than before. Second, in reality, the income was not decreased beyond expectation. During the new holiday, the couple take out to go on a visit, to do their shopping, and to eat out. Third, the household labor time is different by sex. But the husbands is reported that they are participated more in hanging out the laundry, cleaning, and care for children than before. Forth, the family leisure activity of the husbands in comparison with individual activity and wives increased more than before.

  • This study was conducted to identify the educational need of pregnant women, and to evaluate the effect of the 2-hour childbirth class provided by researchers. The subjects were composed of 183 pregnant women who participated voluntarily in the 2-hour childbirth class, and the data were collected by self reporting structured questionnaire designed by researchers. The data were analyzed with descriptive statistics, paired t test, and McNemar test by SPSS pc program. The results were as follows ; 1. Mean age of th subjects was 27 and most subjects graduated from the high school and the college. 80.3% of the subjects had nuclear family. 82.5% of the subjects were full time housewives. 2. 85.8% of the subjects were ipara. Though 71.6% of the subjects might have antepartal care in the clinic, 67.2% of the subjects had no chance to participate in the childbirth class before this study. 3. Subject's health and lifestyle, especially related to eating habits, were changed in the antepartum period. We found that the pregnancy affected positively on health and lifestyle of the women. Over 75% of the subjects became to understand the progress of labor, breath methods during the labor, and perineal exercise. Most subjects changed to think that they could control their body more actively and positively during the labor after participating in the childbirth class. 93.4% answered that 'childbirth class was necessary and important'. Most subjects wanted to be taught the contents, such as postpartum care, breast feeding, and infant care in the childbirth class. In conclusion, pregnant women to attend the childbirth educational program with their husband, and the 2-hour childbirth class provided by the researchers very effective in many aspects. Therefore we anticipated that the childbirth class on basis of pregnant women's needs will contribute to improvement of pregnant women's health and well-being during the labor.

  • 본 연구는 대구 경북지역 학교급식소 조리종사자들의 감정노동이 직무 소진 및 직무 열의에 미치는 영향을 확인함으로써 이들의 감정노동에 대한 기초자료를 확보하고 조리원의 감정노동에 대한 적절한 대책 및 개입요소를 알아보기 위해 실시되었다. 조사는 2014년 3월 3일부터 2014년 4월 25일까지 총 358명을 대상으로 실시되었으며 350부를 분석에 사용하였다. 조리종사자의 일반적 특성에 따른 표면행동과 내면행동, 직무 소진과 직무 열의의 전체 평균 점수를 살펴보면 표면행동 2.38/5.00점, 내면행동 3.46/5.00점, 직무 소진 2.67/5.00점, 직무 열의 3.41/5.00점으로 나타났다. 표면행동 점수는 일반적 특성 가운데 조리사 자격증의 유무(P<0.001)와 이직 횟수(P<0.001), 연봉(P<0.001), 근무학교(P<0.01) 항목에서 유의적인 차이를 보였고, 다른 항목에서는 유의적인 차이를 보이지 않았다. 내면행동 점수는 학력(P<0.001), 조리사 자격증 유무(P<0.001), 고용형태(P<0.001), 연봉(P<0.001), 근무학교(P<0.01), 1일 급식 횟수(P<0.05) 항목에서 유의적인 차이를 나타냈으나 다른 항목에서는 유의적인 차이가 없었다. 직무 소진 점수는 학력(P<0.01), 조리사 자격증 유무(P<0.05), 고용형태(P<0.001), 근무학교(P<0.001), 1일 급식 횟수(P<0.001) 항목에서 유의적인 차이를 보였고, 다른 항목에서는 유의적인 차이를 보이지 않았다. 직무 열의 점수는 조리사 자격증 유무(P<0.01), 고용형태(P<0.001), 근무학교(P<0.001), 1일 급식 횟수(P<0.001) 항목에서 유의적인 차이를 나타냈으나 다른 항목에서는 유의적인 차이가 없었다. 학교급식 조리종사자의 감정노동이 직무 소진과 직무 열의에 미치는 영향을 살펴 본 결과 그들이 사용하는 감정노동의 두 가지 전략에 따라 매우 상이한 결과를 유발하는 것으로 나타났다. 다시 말해 이들이 표면행동을 사용할수록 직무 소진이 높아졌으나 직무 열의는 변화하지 않았으며, 이들이 내면행동을 사용할수록 직무 열의가 높아졌으나 직무 소진은 변화하지 않았다. 특히 조리원의 감정노동은 표면행동이 내면행동에 비해 강한 영향력을 보여주었는데, 이는 감정노동 상황에서 주로 관심을 기울여야 할 변인은 표면행동으로 인한 직무 소진임을 말해주는 것이라 하겠다. 하지만 표면행동이 직무 열의를 낮추지는 않는다는 점과 내면행동과 표면행동의 상관관계가 매우 높지는 않았다는 점을 통해 표면행동 상황에서도 내면행동이 유발될 수 있으며, 내면행동의 증가로 직무 소진을 낮추지는 못하지만 직무 열의를 증가시킴으로써 긍정적인 직무태도를 유지시킬 수 있다 하겠다. 이상의 결과를 바탕으로 본 연구의 시사점을 살펴보면 먼저 이론적인 측면에서 감정노동의 두 가지 전략, 즉 표면행동과 내면행동을 직무장면의 주요 결과변인인 직무 소진과 직무 열의에 대하여 분석하였으며 그 결과 감정노동 전략의 차별적 영향력을 확인했다는 점이다. 다음으로 실제적인 측면에서 감정노동자의 감정노동 행위가 부정적인 결과로만 나타나는 것이 아니라 긍정적인 결과를 유발할 수 있음을 확인하였다. 따라서 향후 조리원을 대상으로 내면행동의 의미, 필요성, 결과에 대한 교육을 통해 긍정적 감정노동 전략을 학습시킴으로써 감정노동 종사자의 직무태도를 긍정적으로 전환시키는 노력을 수행할 기초자료를 확보하였다. 또한 표면행동이 직무 소진에 강하게 영향을 미치는 결과를 바탕으로 볼 때 주기적인 감정노동 진단을 통해 낮은 내면행동과 높은 표면행동을 주로 사용하는 종업원의 경우 직무 소진으로 진행하지 않도록 사전에 개입할 필요가 있다 하겠다. 본 연구는 몇 가지 제한점을 지니는데 먼저 자기보고식 설문조사 연구가 지닌 공통방법편의(common method bias)의 제한점을 본 연구 역시 지니고 있다. 즉 독립변인과 종속변인을 동일한 설문지에서 측정함으로써 변인의 영향 관계가 역전될 수 있는 가능성이 존재한다. 또한 응답자의 응답환경을 통제하지 못했다. 즉 각 작업장 별로 동일한 시간과 환경 하에서 조사가 이루어지지 못함으로써 그로 인한 오염요소가 존재했을 것으로 판단된다. 따라서 향후 연구에서는 위의 제한점이 보완되어야 할 것이며, 연구주제와 관련해서는 학교급식뿐 아니라 다양한 형태의 단체급식소에서 근무하고 있는 영양사와 조리종사자의 감정노동과 그로 인한 결과에 대한 비교연구가 진행될 필요가 있을 것이며, 감정노동 이외의 직무 소진 및 직무 열의에 영향을 미치는 요인들에 대한 연구가 진행될 수 있을 것이다.

  • Since most people spend a large majority of their time indoors (at least in the industrialized countries), indoor air may affect human health more than outdoor air. This study was carried out to characterize the reference and equivalent methods against the low volume method which was promulgated by the Ministry of Health and Social Affairs. The Laser and Piezo air sampler offer the advantage of real time data and low labor costs. The arithmetic mean concentrations were found to be 102.9% (Laser-2 min method) and 65.9% (Piezo method) against low volume method (100%). The statistical analysis procedure for this comparision is linear regression. The linear regression line of low volume method had slopes of 0.5487 and 0.9697 and Y intercepts of 0.0266 and 0.0110 $\mu$g/m$^3$ about Laser (2 min) and (24 h) method respectively. And the correlation coefficients were 0.7271 and 0.9433.

  • This study examines work and family life of married women employed in a manufacturing industry. Data were gathered from the use of fact-to-face interview method from a sample of 230 married working women. The major findings of this study can be summarized as follows : (1) With high rates of change of job, most of the respondents remain unstable in their working situation. It was shown that the important factors influencing job satisfaction of married women are women's life cycle, degree of contribution of wife's income toward total family income, and husband's attitude toward wife's empolyment. The degree of job satisfaction is also strongly influenced by labor structural factors such as pay, work environment and fringe benefits. (2) The amount of household labor time was limited by job-related factors rather than by family-related factors, because among these working women employment itself is necessarily for their subsistance. (3) It was shown that wives participated more actively in their marital communications than their husbands. Most of the respondents showed the syncratic type of the decision making patterns, but this results does not necessarily mean wives exercised an equal power with their husbands. The economic factors and the emotional instability of the husband are the ones mostly influencing marital conflicts of the employed women. It was found that the respondents easily revealed marital conflicts related to personal problems of their husbands(such as extramarital affairs, gambling and alchoholism). However, they tried to overcome the structural conflicts related to authoritarian attitudes of their husbands or economic problems without any complaints. (4) Mothers have difficulty in controlling their adolescent children, due to the weakening of parental authority. Although most of the respondents perceived their employment as having negative impacts on their children, they still have high expectations toward their children. Inspite of low degree of father role expectations and facther role performance of their husbands, most of the respondents anticipated expressive roles as well as traditionally instrumental role from their husbands. Finally, these findings would help us determine family welfare policies in Korea. Improvements in paid and household labor structure of married women should be accomplished at the national level. Also, the acting programs for parent education, marital councelling services, and law enforcement for equal employment between men and women should be provided in our society.

  • To investigate the affecting factors to the fatigue and subjective symptoms of adult women, the author analyzed the data from 300 women from 3 groups, manufacture workes, clerical workers and service workers, from august 31, 1993 to the September 30, 1993. Followings are the results there from. 1. For the physical symptoms of fatigue, more than 50 % of respondens comiained were "eye strain" with 73.7 %, "malaise" with 67.0 % "went lay down side" with 60.7 %, "yawing" with 60.3 % and "feel sleep" eith 50.3 % in that order. There was no statistically significant difference between labor woker group, but the fatiger rate was highest among office group. For the mental symptoms. There was no symptom over 50 % of responders complained. For the neurotic symptoms, more than 50 % of respondents complained were "backache" with 53.7 %, "headache" with 49.7 % "shoulder pain" with 54.0 % and "unconfortable" with 43.3 %, in that order, "backache" was higest in manufacture group, but the other symptoms were highest among office group. 2. For the most fatigue weekday, most women answered monday with 56.0 % thursday with 16.3 % and friday with 12.0 % in that order, but saturday was 2.0 %, and sunday was 2.05 labor worker group answered monday was the most fatigue day. 3. 37.7 % of respondents answered afternoon was the most fatigue hours, but 22.0 % was answered evening difference among groups. 4. Nothing to do with the general characteristics, such as age, residence, sleep hours, personality, health status, and exercise, and working conditons such as means to attend office, time to attend office, job satisfaction, work hours, and work years, the mean scores of subjective symptoms of fatigue was highest among office group.

  • The purposes of this study were to develop standardized indices of staffing needs in each school, foodservice system through work sampling methodology . Conventional school foodservices were classified into 5 groups depending on size of meals served. Commissary school foodservices were also classified into 5 groups by cluster analysis using number of meals served, number of satellite schools, and time for transportation of food. Work measurement through work sampling methodology was conducted in 15 conventional and 21 commissary foodservices during 3 consecutive days from September to October in 1995. Statistical data analysis was completed using the SAS programs for descriptive analysis, cluster analysis, and simple linear regression. The results were as follows : Average points of leveling factors of conventional and commissary foodservices were 1.066 and 1.061 , respectively. Mean labor hours per work force was 328 minutes and 366 minutes in conventional and commissary foodservice , respectively. Standardized work time was calculated using leveling factor, ILO allowance rate (175) , and observational work time. The model for standardized indices of staffing needs was developed based on simple linear regression in each school foodservice system. In conventional school foodservice systems(for 100-1,900 meals per day) standardized staffing needs=3.2497 +0.005267$\times$number of meals served (F=273.1, R-square 0.9750, p<0.001). In commissary school foodservice systems (for 200-1,600 meals per day ) Standardized staffing needs=3.393384 +0.0063$\times$number of meals served (F=30.78, R-square 0.6580, p<0.001).

  • Climate change has resulted in increased frequency and intensity of heat waves, which poses a significant threat to the health and safety of construction workers, particularly those engaged in labor-intensive and heat-stress vulnerable working environments. To address this challenge, this study aimed to propose an interpretable machine learning approach for forecasting personal heat strain by considering the cumulative effect of heat exposure as a situational variable, which has not been taken into account in the existing approach. As a result, the proposed model, which incorporated the cumulative working time along with environmental and personal variables, was found to have superior forecast performance and explanatory power. Specifically, the proposed Multi-Layer Perceptron (MLP) model achieved a Mean Absolute Error (MAE) of 0.034 (℃) and an R-squared of 99.3% (0.933). Feature importance analysis revealed that the cumulative working time, as a situational variable, had the most significant impact on personal heat strain. These findings highlight the importance of systematic management of personal heat strain at construction sites by comprehensively considering the cumulative working time as a situational variable as well as environmental and personal variables. This study provided a valuable contribution to the construction industry by offering a reliable and accurate heat strain forecasting model, enhancing the health and safety of construction workers.

  • An investigation was made of the effect of carrot variety and harvest time (DAP) on the composition of carotenoids and the Retinol Equivalent value by column chromatography, and of the relation of the total carotenoid content to the Retinol Equivalent by regression analysis. The results are summarized as follows : 1. There were very significant differences of total carotenoid, ${\alpha}-carotene,\;and\;{\beta}-carotene$ contents among carrot varieties and between two harvest times(90 DAP, 99 DAP). Especially, each component of carotenoids in carrots harvested at 99 DAP attained higher concentrations than 90 DAP. 2. Retinol Equivalent value showed the tendency to increase as the numbers of DAP incr The Shindaehyung-Ochon and Hongshim-Ochon varieties had the highest RE. value. 3. In the composition of carotenoids and Retinol Equivalent value, the Shamgae-Ochon variety had the nearest value to the mean of all variety. Therefore, it is most reasonable to use the Shamgae-Ochon variety for the analysis of vitamin A value in carrots. 4. The regression of the totel carotenoid (x) to the Retinol Equivalent (y) was y = 0.074 + 0.12x $(r^2$ = 0.91). So, if total carotenoid content is determined, R.E. value can be predicted by this regression equations, saving time and labor.
