Given the dramatic increase in the percentage of married women working in clercial occupations and the inflexibility of work commitments for employees working in this domain, this paper investigates the division of household labor between married female clerical workers and their husbands, and their sources of external help. The total housework time of couples, the percent of total housework done by husbands, and a scale measuring the wife’s perception of the frequency with which her husband does specific household tasks are all used to measure the division of household labor between couples. Data for 143 couples were gathered from using structured questionares and the time dairies that included one weekday and one weekend day. The findings of this study are as follows; 1) The couples receive substantial support in housework from their mothers. 2) Wives spend an average of 23 hours and 26 minutes per week on household labor, whereas husbands spend an average 7 hours and 7 minutes per week. Husbands do an average of 20.9% of all housework done by the couples. Wives typically perceive that their husbands are not frequently participating in a variety of household tasks(mean = 2.88 on a 5-point Likert scale where 1=never and 5=always). 3) Multivariate analysis reveal that working hours is negatively related to while the presence of child under 6 years old is positively related to total housework. Time availability variables(e.g. working hours and the presence of child under 6 years old) and relative resource variables(e.g. the rate of wife’s income on that of husband) are related to the percent of total housework done by husbands. The sex-role attitude variables are related to the wife’s perceptions of the frequency with which her husband does specific household tasks.

본 연구에서는 패스트푸드점 아르바이트생 118명과 패스트푸드점 외의 음식 관련 서비스업에서 일하는 아르바이트생 115명을 대상으로 설문조사를 실시하여 식습관과 패스트푸드에 대한 인식 및 패스트푸드 섭취 빈도 등을 비교하여 두 집단 간에 차이가 있는지를 남녀별로 나누어 파악하고자 하였다. 남자의 경우 패스트푸드점 아르바이트생과 그 외 아르바이트생에 있어서 연령, 신분, 주거형태, 용돈, 음주, 흡연, 일하는 시간 및 시급에는 차이가 없었으며, 음주횟수에 차이가 있었다. 여자의 경우 패스트푸드점 아르바이트생은 그 외 아르바이트생에 비해 20세 이상의 대학생이 더 많았고, 6시간 이상으로 일하는 학생이 많았으며, 시간당 급여가 더 높았다. 여자의 경우 패스트푸드점 아르바이트생이 그 외 아르바이트생에 비해 식사 횟수는 적고, 간식으로는 패스트푸드를 먹는다고 한 사람이 더 많았으며, 남녀 모두 야식을 더 자주 먹는 것으로 나타나 식습관이 더 나쁜 경향이 있었다. 또한 패스트푸드점 아르바이트생은 그 외 아르바이트생에 비해 남자의 경우 과일류의 섭취빈도, 여자의 경우 콩 및 콩제품의 섭취빈도가 유의적으로 낮았다. 또한 패스트푸드점 남자 아르바이트생은 패스트푸드의 장점에 대한 인식 점수가 더 낮았다. 패스트푸드점 아르바이트생은 남자의 경우 햄버거류, 피자류, 탄산음료, 여자의 경우 햄버거류, 감자튀김, 도넛, 탄산음료에서 그 외 아르바이트생보다 유의적으로 섭취빈도가 높았으며, 연령, 신분, 주거형태, 용돈, 음주, 흡연, 일하는 시간, 시급 등으로 보정한 후에는 남녀 모두 햄버거류, 피자류의 섭취빈도가 유의적으로 높았다. 총 섭취빈도도 패스트푸드 아르바이트생의 섭취빈도가 더 높았으며, 연령, 신분 등으로 보정한 후에도 여전히 유의적인 차이를 나타냈다. 이와 같이 패스트푸드점에서 일하는 아르바이트생은 그 외아르바이트생보다 식습관이 더 나쁘고, 패스트푸드를 더 자주 섭취하고 있었다. 따라서 패스트푸드 아르바이트생은 결식하지 않고, 다양한 식품을 충분히 섭취하도록 노력하는 등의 좋은 식습관을 갖도록 더 노력해야 할 것이며 이를 도울 수 있는 영양교육이 요구된다.

This study cheked on the general tendency of the value consciousness of working teenagers about family life and how it was affected by demographic and psycho-social variables. In that way modern korean family life making trouble with the traditional family relationship can comprefhensively be understood. And this study 500 copies of the questionnare were given to them and 478 copies were for use in the final information of analysis. Data was analyzed by frequency distribution percentage mean Pearson's product-moment correlation analysis and stepwise multiple regression analysis. The results are summarized as follows. 1) The value consciousness of working teenagers about family life shows a modern tendency on the whole 2) The value consciousness about family relationship comparatively shows a traditional tendency.

The number of people working in their own home has been increasing, and this will change the form of house. Therefore, it is necessary to plan the new house for the people working at home, and to offer business related working area. This study was designed to know the office workers preference for spatial characteristics of home office. Data were collected through a questionnaire survey. The subject were 257 office workers living in Seoul area. Frequency, percentage, and MM2 : $\textrm{X}^2$-test were used. The results showed that the place for home-office should be located independently inside house. The desirable size for the home-office might be 3-4 pyung. If the place for home-office share with other places, livingroom of bedroom, it is necessary to develop furniture and partition matching with residential furniture and atmosphere. Office workers prefer U-shaped workstation and coner-shaped workstation.

According to the results of analyzing the formation enterprise of beautiful public latrines, which Chungcheongnamdo is promoting, the conclusions of this study are as follows. The design for construction form should be suitable well for the surrounding environment according to the installation place of public latrines. Construction scales and sanitary appliances should be decided according to the location, use personnel, use frequency, and user type of latrines. It is not desirable to decide working expenses on the basis of pyeong irrespective of construction scale. In the purchase of building sites, because the building sites owned by the nation or the public bodies are difficult to apply the related laws, it is difficult to construct public latrines as eternal facilities. Because the building sites owned by individuals are very expensive, the execution of enterprises is difficult. Therefore, it is necessary to simplify the administrative procedures and increase the working expenses.

High frequency signal injection (HFI) is an alternative method for estimating rotor position of interior permanent magnet synchronous motor (IPMSM). The general method of frequency and amplitude selection is based on error tolerance and experiments, and is usually set with only one group of HF parameters, which is not efficient for different working modes. This paper proposes a novel rotor position estimation scheme by HFI with optimized frequency and amplitude, based on the mathematic model of IPMSM. The requirements for standstill and low-speed operational modes are met by applying this novel scheme. Additionally, the effects of the frequency and amplitude of the injected HF signal on the position estimation results under different operating conditions are analyzed. Furthermore, an optimization method for HF parameter selection is proposed to make the estimation process more efficient under different working conditions according to error tolerance. The effectiveness of the propose scheme is verified by the experiments on an IPMSM motor prototype.

본 연구에서는 카메라 생산 시스템의 모터가 Z축 방향으로 작업할 때 시스템에 발생하는 위험진동수를 해석하였다. 모달해석을 통하여 얻어진 결과를 보면 두 가지 모델에 발생한 고유진동들에 있어서의 각 모드의 형상을 조사할 수 있다. 본 연구 시스템에서 고유진동수 범위는 100Hz부터 500Hz로 나왔다. 모터의 무게가 20kg인 경우에 모델의 최대 등가응력이 6.2335MPa로 발생하는 것을 확인할 수 있고 이 값은 모터가 10kg인 경우의 최대 등가응력 값보다 50배 큰 것으로 나타났다. 본 카메라 생산 시스템의 고유진동과 하모닉 응답해석을 통하여 시스템의 작업 안전성을 고찰할 수 있었다.

The purpose of this study is to analyze the charging gas effect on the resonance and performance characteristics of the linear compressor for small scale FPFD Stirling refrigerator. To ensure high performance of FPFD type Stirling refrigerator, the operating frequency of the refrigerator should be around the natural frequency of compressor. The gas spring effect which is induced from Pressure change in cylinder due to motion of pistons has significant effect on the natural frequency of the compressor. The numerical results show the linear compressor has high natural frequency when the charging pressure of working fluid is high and the stroke of compressor, current, input power and efficiency of compressor were shown with different operating conditions.
