본 연구의 기본적 취지는 부인과 남편의 가사와 자녀 양육노동시간에 영향을 미치는 결정요인을 조사하는 것이다. 연구목적을 효과적으로 달성하기 위하여, 가사분담 및 육아시간 설명에 유용하게 쓰여온 다양한 관점의 이론을 도입하여, 그 효과를 검증하였다. 본 연구에서 도입된 이론은 경제적 효율가설(Economic Efficiency), 수요 및 실행가능가설 (Demand/Response Capability), 성 역할관념가설(Sex-Role Ideology), 그리고 상대적 자원가설(Relative Resources)이다. 이 가설들로부터 유출된 대용변수들의 부인과 남편의 가사와 육아시간에 미치는 효과가 검증되었는데 이 변수들은 임금률 부부간의 임금률 비율 노동시 장에서의 근로시간 어린자녀 수 성별에 따른 역할에 대한 사고관, 소득, 부부간의 상대적 소 득수준 교육수준 직업 연령 가족형태, 인종이었다. 본 연구에서 사용된 조사는 1988년 미국 위스콘신 대학 (메디슨)내의 인구 및 생태국(Center for Demography and Ecology)에서 실시한 전국 가족 및 가계조시(National Survey of Families and Households)이다. 부인과 남편의 가사 및 육아 시간량을 설명하는 이론의 효과검증에 대한 연구 결과를 요약하면 역할 관념가설을 부인과 남편모두의 가사 및 육아노동 시간을 잘 설명하는 가설로 나타났고 수요 및 실행가능성가설은 남편보다는 부인의 가사와 육아시간에 더 설득력있는 가설임이 밝혀졌다. 대체적으로 경제적 효율가설과 상대적 자원가설의 효과는 크지 않은 것으로 나타났다. 또한 수요 및실행가능가설이 남편의 총가사시간을 설명하는 효과는 크지 않았으나 남편의 여성중심형 과업시간에는 유의마한 변수로 나타난 것은 주목할 만하다.

페이징 시스템의 발달과 시행은 오늘날 특정 영역 내에서의 진보가 다른 영역의 균형있는 발전에 얼마나 많이 의존하고 있는가를 보여주는 전형적인 예이다. 과거의 페이징 시스템은 한 공장의 근로자에게 혜택을 주었다. 위성을 이용하는 미래의 페이징 시스템은 전세계 모든 곳의 모든 사람에게 다양한 혜택을 제공해 줄 수 있게 된다. 점진적으로, 한 쌍의 킬로미터와 점선으로 연결된 전구와 벨은 처음으로 무선시스템으로 대체되어 한 국가라는 지역을 넘어서 서비스를 제공해 왔다. 디지털 기술의 개발을 포함해서, 무선 설비가 소형화 됨에 따라 이러한 일은 점차적으로 이루어져 왔다. 따라서 전기통신에 의한 우주 무선통신과 특히 정지위성 시스템의 엄청난 발전으로 전세계는 가까워지게 되었지만 거의 엄청난 비용과 이용자들이 갖춰야할 것들 때문에 이러한 영역에 접근하는 것은 거의 한정되어 방송용으로만 준비되어 왔다. 오랫동안 LEO 위성은 과학적, 군사적인 용도로만 이용되어 왔는데 그것은 이 위성이 원래 가지고 있는 문제점들로 하루마다 지평선 위의 아주 짧은 통행로와 관계된 것 때문이었다. 그러나 현재는 하나의 시스템을 형성하기 위해 수많은 LEO 위성들의 발사를 감당해 낼 수 있는 장치와 여러 영역에서의 공동작용(synergy) 덕분에, VHF대의 아주 저렴한 시설을 이용한 경제적, 기술적 장점을 인식하고, 혼신을 다하여 다이내믹 채널 활동지점 시스템(denamic channel activity assignment system)을 개발하였고, 마지막으로 말하지만 결코 가볍게 인식해서는 안될 WARC-92가 필요한 주파수대를 지정해야한다는 의도를 밝힌 것 등이 개인간의 통신을 전세계적으로 확대하는데 있어서 디딤돌이 될 것이다.

Switch box is metal box and used for electric wire pipe in building. In manufacturing switch box, we need 5∼6 press machines, 5∼6 dies, 1 tapping machine. and 7∼8 operators. What matters is rise of manufacturing cost and operators' reluctance of working. To solve this problem, we modified the pre-existing die and developed handling mechanism, which leads to improve the manufacturing process. After the research and development, we could reduce the number of machines and workers needed in the process; 2 press machines, 2 dies, 1 tapping machine, and 1 operator. That means we can save labor and the number of operators needed, reduce manufacturing cost, and get the effect of import replacement.

An analysis of the correlation in port-related industries between minimum wage and employment effects, showed that it was very insignificant. However, there are some differences between commercial and temporary workers, those that are self-employed, and other workers in the private sector. Thus, while commercial workers are somewhat stable, they have a somewhat negative effect on temporary workers and self-employed people. At the Minimum Wage Council, the minimum wage hike is seen as stable because of the interaction between income and substitution effects in the labor market. According to the analysis, the port-related industries were affected more by the global economic recession and domestic economic volatility than the variables related to the minimum wage hike.

The purpose of this study is to determine the working conditions and demands of the assistant workforce at childcare centers, and to provide suggestions on policies for childcare teachers. To achieve the purpose of the study, a total of 190 assistant teachers, nursing helpers, alternative teachers and others were surveyed online during the month of August 2017. The survey examined the employment route and working motives, working conditions and environment, job and educational difficulties for analyzing the work conditions and demands of ancillary staff. For the analysis method, SPSS 12.0 was used to analyze frequency and difference. The main findings are as follows. First, childcare center assistants were able to work at their respective times, making it mandatory for them to enter the workforce, and making job openings for ancillary teachers. Second, 73.7% said the daily working hours were '4 hours to 8 hours' under the conditions and 57.9% said 'More than 510,000 won to less than 1 million won.' Average amount of rest time per day was about 30 minutes, and 17% had no rest periods. Third, based on the job and education status, ancillary personnel performed "infant and child guidance and interaction", "Cleaning and cleanliness related tasks" most actively, and "care for cleaning and cleanliness" and "care for morning and night care". Fourth, in the job trouble and difficulty, ancillary staff found it difficult to satisfy with wage related complaints and job insecurity, and the reason for agreeing to the non-regular workforce becoming a regular worker was found to be due to the stability of employment. Lastly, the most urgent tasks to solve the problem of non-regular workers were to fill the wage gap between regular and irregular workers, shorten the working hours and improve the working conditions. The policy implications are presented based on the above findings.

This study was intended to collect the baseline information on health status, nutrient intakes and dietary self-efficacy according to the obesity levels of male workers. Nutrient intakes of 224 male workers were assessed by 24 hr recall method; also, dietary attitude and dietary self-efficacy were investigated by self-administerd questionnaires. Biochemical characteristics such as blood pressure (SBP, DBP), total cholesterol(TC), hemoglobin (Hb), blood glucose (BG), SGOT, SGPT and ${\gamma}-GTP$ were assessed. Subjects were divided into normal, overweight and obese groups by body mass index (BMI). The health status was analyzed as normal group, health concerned group and disease suspected group. Weight, percent ideal body weight (PIBW), BMI and body circumference (waist, hip) and waist-hip ratio were high in the order of obese group, overweight group and normal group. Body fat mass was high also in the order of obese, overweight and normal group. Blood pressure (SBP, DBP) was the highest in obese group. SGOT, SGPT, ${\gamma}-GTP$ were higher in the obese group than normal and overweight groups. It was Proven that the percentage of those evaluated as low nutrient intakes were 71% for Ca, 50.9% for Zn, 70.5% for vitamin B2, 56.3% for vitamin C and 81.3% for folic acid. The dietary attitude scores were high according to the dietary self-efficacy. The age was positively correlated with dietary attitude, and the dietary attitude was positively correlated with dietary self-efficacy and total energy intakes. Dietary attitude showed the greatest total causal effect in relation to dietary self-efficacy. The results of this study showed some health problems and nutritional problems, indicating the need for nutritional management for male workers.

The purpose of this study is to analyze the economic effectiveness of advanced enterprise welfare system utilizing DEA(Data Envelopment Analysis) and contribute to the adoption and implementation of the system conducted by Korea Workers' Compensation & Welfare Service(COMWEL). We classified 48 sample data into 3 categories : A category(basic consulting & intensive consulting, adoption) is 36, B category(basic consulting & intensive consulting, non-adoption) is 5, and C category(only basic consulting, adoption) is 7. A consulting fee is used as input variable, earning per employee and average employee tenure are used as output variables. As a result from DEA, we find out the fact that the economic effectiveness of A category is better than the economic effectiveness of B and C category and it comes to the conclusion that the consulting service provided by COMWEL has a positive effect on the adoption and implementation of advanced enterprise welfare system. Therefore, COMWEL is required to perform consulting service to small & medium business more actively and is needed to look at the reason why some businesses hesitate to accept the relevant system.

In the absence of a male provider the state must decide how far and under what conditions it will provide for the mother and her children. In the case of lone mothers, there are three main possible sources of income: the labour market, the absent father, and the state. However, the relative proportions of these three sources vary significantly from country to country as well as from individual to individual within the group of lone parents. Until very recently the UK has been alone among countries of the EU in allowing lone parents to draw benefits without making themselves available for work so long as they have dependent children. However, in the 1990s, the UK government introduced major changes to his policies regarding lone parents. The UK government attempted to restrict the role of the state as a source of income for lone parent families. At the beginning of the 1990s, the emphasis in the UK was put on securing more money from 'absent fathers' to maintain. However, the policy was unsuccessful and by the mid-1990s attention to the only other possible source of income for lone parent families, the labour market, was stepped up, notwithstanding the ambivalence of politicians about the desirability of women with young children entering employment. From 1998 the Labour government introduced a series of reforms aimed at reducing both worklessness and poverty by raising welfare payments to families both in and out of work, improving financial incentives to work and introducing a more proactive welfare system. The results presented here suggest that these policies have raised the employment rates of lone parents by around 5 percentage points, or 80,000. These employment gains have come from a welfare reform package that does not require lone parents to search for jobs, or uses time limits in welfare programmes. In addition these gains have been achieved despite generous increases in welfare payments for lone parents who do not work. These earnings gains combined with the more generous welfare are making rapid progress in reducing lone parents' poverty.

People generally focus on the supply side when conducting a study on the movie industry. However, to understand the movie industry better, one needs to analyze both sides - the demand and supply of movies. This paper analyzes demand-side factors that have long been taken for granted in Korea's movie industry. The study used data for 1991~2008 on the following demand-factors : the average ticket prices, the number of working days and hours, the average personal income, the number of spectators for the two major professional sports, cable TV, the number of movies released each year and the number of movie screens. This study shows that ticket prices do not conform to the law of demand. According to the law of demand, increasing price leads to a decline in demand. However, in reality, the number of viewers went up along with ticket prices. The study found that demand for movies was correlated to income levels and leisure time. An increase in the number of leisure hours and income levels pushed up demand. Contrary to general belief, a growth in the availability of substitutes, such as professional sports(soccer and baseball), did not result in a fall in demand for movies. The audiences for both sports and movies grew simultaneously as the amount of leisure time increased. Contrary to the general expectations that more diversified genres of movies will draw larger audiences by satisfying different individual tastes, the diversification had little impact, but the number of movie screens was positively correlated with audience size. In sum, changes in ticket prices and the quantity of substitutes had little influence on demand in the movie industry. Rather, it was the supply side of the industry that induced demand.

With the introduction of the maritime safety supervisor system in Korea following the passenger vessel Sewol accident, the safety control system for coastal vessels has been reinforced. A maritime safety supervisor performs marine accident prevention activities by offering periodical or occasional guidance and supervision. When a deficiency is found during guidance or supervision sessions, an order for improvement is issued to rectify the problem by such measures as supplementation or replacement of vessel facilities, improvement of work hours and working conditions for employees, educational and training programs for executives and employees, or the improvement of other affairs relating to maritime safety control. However the present order for navigation suspension by a maritime safety supervisor is limited solely to supplementation or replacement. For this reason, orders for navigation suspension against other facilities is impossible, even if a serious deficiency that could lead to a marine accident such as poor cargo loading conditions or unqualified crew is identified. Therefore, the order for vessel navigation suspension to secure seaworthiness should be expanded to include cargo loading/unloading operations, certificates and documentation, maritime safety management systems, and human elements including emergency drills and working conditions, in addition to the supplementation or replacement of vessel facilities that exists.
