본 연구에서는 아산시의 풍기처리구역을 대상으로 건기시 하수발생량 및 농도의 시간적, 공간적 변화를 조사하였다. 또한 주중과 주말의 하수발생 특성을 알아보기 위해 조사기간내 연속측정된 하수발생량을 요일별로 나누어 각각의 하수발생특성을 조사하였다. 조사 결과 주거지역인 풍기처리구역은 상업지역과는 다르게 직장인의 퇴근 후인 저녁시간대에 하수량이 증가하였다가 점차로 감소하여 새벽녘 4시경에 최소가 되는 것으로 조사되었다. 수질농도는 하수의 피크유량이 발생하였을 때 상대적으로 높았고, 최소유량이 발생하는 새벽시간대에 가장 낮은 농도를 나타내는 것으로 조사되었다. 주중과 주말의 하수발생 특성을 보면, 상업지역의 하수발생량은 주중과 주말의 차이가 뚜렷하게 나타나지 않는 반면 주거지역의 하수발생량은 주말에 직장인들이 가정에 머무르는 시간이 많아지면서 하수량이 증가하는 것으로 조사되었다.

In order to identify and understand the crucial factors to induce traffic accident, causal relationships between diverse factors and traffic accident occurrence have been investigated continuously. It is one of most important issues all over the world to reduce the number of traffic accidents and deaths by them. Korea government is also stepping up their effort to reduce the number of traffic accidents and mitigate the severity of the accidents by establishing various traffic safety strategies. By introducing the five-day work week and increasing concern of leisure activities, the differences of trip characteristics between weekday and weekend is getting greater. According to this, the patterns and crucial factors of traffic accident occurrence in weekend appear differently from those in weekday. This study aims to understand major different factors affecting accident severity between weekday and weekend using 12,042 incident data occurred on freeways of Korea from 2006 to 2011. The model developed in this study estimated relationships among various exogenous factors of traffic accident by each type using SEM(Structural Equation Model). The result provides that road factors are related to the accident severity for weekday model, while environment factors affects on accident severity for weekend.

This article aims to reveal the ways in which a "space of difference" is produced and interpret the space as a heterotopic space, drawing the case of Filipino elderly care-givers in Israel. The in-betweens and temporariness of the migrants'experiences in the Israeli society lead to the creation of a heterotopic space. Paying attention to their particular life rhythm as live-in care-givers, namely weekdays-workplace and weekend-flat, this article explores how the migrant care-givers build their own society through a variety of spatial practices and multiple social relations based on the flat. In making the flat a perfect form of a lifestyle for their own, the migrants inscribe their presence in the flat in unique ways for different purposes, in a way different to that which surrounds it. However, the structure of flat not only signifies the migrants' marginality but also reflects the challenging position. The flat has functions in relation to all other space that remains, even if such connection often creates effects of contrast and difference. In this light, the flat is not merely an alienated and circumscibed exotic migrant enclave but a heterotopic space which is dynamically constructed in relation to other sites in the wider societal order.

This study conducted five day school week as seeking direction for programs and policies that meet the needs of weekend activities want the satisfaction of youth to find out what to investigate. For purpose, actually a lot since five day school week and weekend programs whether or not to participate, hope to weekend programs, weekend activities operating in the way were examined. Findings, for the first five day schol week of youth satisfaction than girls, boys lower was, since five day school week and weekend program participation rates were lower. Most since five day school week in activities with friends, sleep, games or Internet, hobby alone, watching TV, family and activities in order appeared. Young people can study their aptitude to live autonomously in a student-centered curriculum of education is required, arising from a rapidly changing society and human relationships, social problems, to respond to a variety of leisure time, and to participate in the program will be provided an opportunity. Lessons five day school week, increased leisure time of youth, school, and community for the desired program, you will need to plan and operate with local conditions.

The national capacity of electricity of Korea was 81,737 MW and the peak demand was renewed by the record of 71,230 MW in 2012 which has been increasing since the first lighting ceremony had taken place in the Royal Palace(Kyung-Bok Goong) in 1887. Aa the counteract on the rapid increasing of the demand, Korean government is constructing and operating the high capacity nuclear and thermal power plants, however, the operating reserve on weekdays is small while those of weekends are more than 40% of capacity, so they are providing the pumped-storage power plants with the surplus electricity during weekends and operating the power plants which cost higher production price and located in the capital area with WSS (Weekly Start and Stop) mode including the Seoul Thermal Power Plant. Since the Seoul Thermal Power Plant is spending huge amount of expenses for more than 30 times of the WSS annually due to the high production cost even though it is in Seoul, the core of the demand, I chose the power plant unit #5 which was on the grid in 1969 for the case to confirm reducing 23% of the warm start-up time by applying the "Start-up time management program", and that reducing 35% of the water temperature increasing time by accelerate the increasing rate of the inlet temperature of the water circulating pump.

도시화, 산업화로 인해 도시는 그 주변지역보다 기온이 높은 도시열섬 현상이 발생하고 있으며 이는 인간 활동에 의한 인공폐열 배출량의 증가에 기인한다. 이러한 인간 활동에 의한 도시기온의 변화는 도심과 농촌지역의 차이로 인한 공간적 변이와 아울러 주중과 주간에 기온 차이가 발생하는 시간적 변이를 포함하고 있으나 도시열섬현상의 공간적 변이에 의한 연구에 비해 시간적 변이에 의한 연구는 많이 수행되고 있지 않다. 본 연구에서는 서울 도심의 주중과 주말의 기온차이를 다년간 관측을 통하여 주중과 주말의 주간 변동의 특성을 파악하여 도시 기온의 시간적 변이를 파악하기 위하여 서울시 강남구를 사례로 2007년 10월 31일부터 2010년 12월 11일까지 약 3년간 관측한 자료를 이용하여 분석한 결과 5개 관측지점 모두 주중(weekday)이 주말보다 $1.6{\sim}1.7^{\circ}C$ 기온이 더 높았으며 이는 주중에 도시 내에서 방출하는 인공폐열의 양이 더 많음을 의미하며 고밀도지역은 냉난방수요가 많아 토지이용에 따라 기온의 차가 크므로 이를 저감시키기 위한 도시 및 조경계획이 필요하다.

This study examines the impact of sleep duration on Korean adolescents' suicidal impulse. A gender-based analysis was conducted using binary logistic regression method. The major findings are as follows. First, weekday sleep duration had a significant effect only on male adolescents. Male adolescents who sleep less than seven hours on a weekday are likely to experience suicidal impulse by 1.9 times higher than the others. This effect remained significant even when other relevant variables were controlled. On the other hand, female adolescents who have less than seven hours of sleep on a weekday have about 1.3 times higher chances to experience suicidal impulse. However, this effect became insignificant when other variables such as stress were controlled. Meanwhile, weekend sleep duration did not have any significant effect on both male and female adolescents. By demonstrating the different effects between weekday/weekend sleep duration and male/female adolescents, this study supports the claim that it is necessary to take a social approach in studying sleep duration.

The aim of this study was to evaluate the nutritional status of elementary and middle school students by gender with an emphasis on comparison of nutritional intake between weekday and weekend. Survey construct included one 24-hour diet recall and two diet records, short food frequency questionnaire, and anthropometry. Eating behaviors and nutritional intake were largely different for four groups divided by age and gender: ME, FE, MM, and FM. Frequency of consumption of healthful foods was significantly higher in the ME and FE groups. The highest and lowest scores for frequency of eating with parents were observed in the FE and FM groups, respectively. The amount of consumption of food groups was lower on weekends than on weekdays and this trend was more prominent in elementary schoolers compared with middle schoolers. In terms of food group consumption as well as energy and nutrient intake, the ME group showed the greatest differences between weekday and weekend, followed by FE, MM, and FM, in descending order. A significantly higher amount of potassium, phosphorus, and calcium was consumed on weekdays than on the weekend in the ME and FE groups. The amount of energy and nutrient intake was smallest in the FM group; however, the difference between weekday and weekend was minimal as well. In comparison of the subjects' energy and nutrient intake with their Korean Dietary Reference Intakes values (%KDRI), the MM group showed the most undesirable results for energy, protein, dietary fiber, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, vitamin $B_6$, calcium, and zinc. Overall, findings indicated that nutritional intake status may differ between weekday and weekend for elementary and middle schoolers by gender, suggesting that youth may benefit from nutritional education programs that stress the impact of gender and weekend effect on their dietary intake.
