The purpose of this study is to compared the length of working hours and its effects on family life for Korean and Japanese full-time working couples. For this study, the survey used structured questionnaires and time diaries(one weekday and holiday), and the data were collected in the fall of 1995. A subsample of full-time working couples, 82 couples from Seoul and 79 couples from Tokyo, was used for the purpose of this study. The major findings are as follows; 1) On average, the weekday working hours of Korean husbands were longer than Japanese husbands(11 hours 31 minute, 10 hours 52 minutes a day, respectively). Wives in both countries worked almost identical lengths of time (9 hours 2 minutes in Korea and 8 hours 42 minutes in Japan). Working hours of husbands were longer than those of wives in both countries. Husbands' overtime. Almost (90%) of our Korea sample worked 6 days or 5 1/2 days per week, however the majority (69%) of our Japanese sample worked only 5 days per eek. 2) More Korean husbands and wives reported that their family life was constrained by wives working hours than their Japanese counterparts did. 3) All wives in both countries reported that the husbands long working hours has effects on quality family time. Korean wives perceived that their working hours had effects on time spent on child care, however Japanese wives perceived that their working hours affected their personal time and housework time. Korean husbands agreed with their wives working hours negatively affected their personal leisure time. Japanese husbands reported that their working hours negatively affected their sleeping time.

As use of construction equipment has been increasing continuingly, the proportion of equipment expense to the total construction cost has become higher. However, there is a difference between the equipment expenses section in 'Poom-Sam' and practical data, because 'Poom-sam' does not consider non-working days due to weather conditions, legal holidays and management conditions. Therefore, 'Poom-Sam' does not present a reasonable standard for estimating construction equipment expenses. In this study, to estimate realistic construction equipment operating hours, firstly, construction equipment was classified according to work, and weather conditions, in which each work could not be executed, were established. Then, weather data on Seoul and Busan($2004{\sim}2006$) and legal holidays were analyzed to suggest annual standard operating hours. The annual standard operating hours of earthmoving & excavating, compaction, and drilling equipment was estimated to be 1,430 hours, and lifting equipment, concrete paving equipment, asphalt paving equipment, concrete equipment, and crushing & conveying equipment were estimated to be 2,124 hours, 1,156hours, 1,188hours, 1,688hours, and 2,152hours respectively.

Purpose: This prospective study was designed to investigate the incidence of acute postoperative pain (APP) ${\geq}4$ and the risk factors of APP${\geq}$ for the first 48 hours after surgery. Methods: Data from 531 surgical patients were collected from November, 2009 to May, 2010. APP was assessed from the time of arrival at the Post Anesthetic Care Unit (PACU) to the end of the post-operative 48 hours. Risk factors of APP${\geq}$ were analyzed by logistic regression analysis. Results: The incidence of APP ${\geq}4$ was 58.8% for the first postoperative 4 hours; 33.5%, 24 hours; 11.1%, 48 hours. The score of pain was 5.55, the highest on arriving at PACU; 5.03 at postoperative 30 minutes; 4.03 at 1 hour; 3.96 at 4 hours; 2.76 at 24 hours; 1.44 at 48 hours Risk factors for APP ${\geq}4$ were females (Odds ratio [OR], 1.94; p=.013), general anesthesia (OR, 4.29; p<.001) and patient controlled analgesia (PCA) (OR, 2.83; p<.001) at 4 hours after operation; body mass index (BMI) ${\geq}25$ (OR, 1.80; p=.009), duration of surgery ${\geq}1$ hour (OR, 2.87; p=.037), general anesthesia (OR, 3.99; p<.001) and PCA (OR, 6.23; p<.001) at 24 hours; general anesthesia (OR, 3.53; p=.003) and PCA (OR, 3.01; p=.013) at 48 hours. Conclusion: Surgical patients with BMI ${\geq}25$, PCA and general anesthesia seem to have a higher incidence of pain ${\geq}4$ through the first postoperative 48 hours.

This study aims to examine the moderating effects of work hours between job stress and quality of life of young farmers. A survey was conducted on 618 young farmers for one month from July 1, 2022. The main analysis results are as follows. First, quality of life and job stress, quality of life and work hours had a negative correlation, and job stress and work hours had a positive correlation. Second, work hours were found to have a moderating effect on the relationship between job stress and quality of life. Third, as a result of identifying the area of significance of work hours, it was found that work hours played a role in moderating the relationship between quality of life and job stress when work hours were longer than 1.327 hours. Fourth, as a result of visualizing the moderating effect by dividing work hours into three groups: high, medium, and low, it was found that even if the level of job stress was the same, the farmers with long work hours perceived their quality of life to be worse than those with shorter work hours. It can be said that in order for young farmers to settle down and live stably in agriculture and rural areas as professionals, it is very important to actively develop and support policies to improve the working environment in the agricultural sector that can secure time to enjoy culture and leisure and relieve job stress.

Purpose: This study analyzed the relationship between working hours and the occurrence of industrial disasters based on manufacturing businesses that are members of Federation of Korean Trade Unions.Methods: Repliers were managers of the safety & health department in the union, and 215 surveys out of 300 businesses that agreed to participate in the research were analyzed. Results: 94 out of 300 companies, which counted for 43.7%, replied to have experienced industrial disasters. 56 of those (59.6%) had less than 52 working hours per week, and 38 companies (40.4%) had more than 52 working hours per week. 109 companies, which counted for 50.7%, did not have an incident of industrial disaster. Companies with an average of more than 52 hours of working hours per week were shown to have a 2.29 times (95% CI 1.08~4.87) higher possibility of having industrial disasters than those with less than 52 hours of working hours. Conclusion: As the study showed that industrial disasters were more likely to occur in businesses with working hours longer than 52 hours, ways to reduce working hours need to be developed and various safety measures need to be taken to prevent industrial disasters in case workers are undergoing long working hours.

South Korea has the highest policy priority for working hour regulations because it has longer annual working hours than other Organization for Economic Development Co-operation and Development countries and has fewer holidays. According to the results of the Working Conditions Surveys between 2006 and 2020, in 2020, 6% of wage earners worked for > 52 hours weekly. The percentage of workers exceeding 52 hours weekly has decreased over time; however, disparities exist based on age, industry, occupation, company type, and company size, particularly in service-, arts-, and culture-related occupations and workplaces with fewer than 5 employees. South Korea's working hours system is greatly influenced by the 52-hour weekly maximum; sometimes, a maximum of 64-69 hours, including overtime, is theoretically possible. To ensure healthy working hours, it is important to actively protect workers who fall through the cracks, such as those in businesses with fewer than 5 employees.

Public Libraries should be open at times when the community can make the most effective and convenient use of library collections and services. In other words, public library must provide adequate open hours for local residents. In this respect, this study analyzed the minimum opening hours per week in public library standards of international organizations(IFLA/UNESCO) and major countries (USA, Canada, UK, France, Australia, China, Taiwan, Japan, Korea) and suggested a desirable minimum standards(under 10,000 population-45 hours ; over 10,000~20,000 population-50 hours ; over 20,000~50,000 population-55 hours ; over 50,000~100,000 population-60 hours ; over 100,000~300,000 population-65 hours ; over 300,000 population-70 hours) for opening hours per week of public library based on population size in Korea.

This dissertation classifies sample patients by a measure of K-DRG to identify the most frequent group. and investigates the differences in the dependency of nursing by patient classification system in the SICU of Seoul National University Hospital in Korea. It also calculates the mean nursing care hours and costs per craniotomy patient, who is shown to be the most frequent patient group. The results of the research can be used as basic data for the development of relevant nursing cost system in the future. The results of the research are as follows: 1. Using data from 97 sample patients, as many as 26 groups are identified when the patients are classified by K-DRG. KDRG-001 (craniotomy) is found to be the most frequent group(43.30%). 2. The result from patient classification system grouping in craniotomy patients shows homogeneity in terms of dependency of nursing with 35 patients in the 4th group, 145 patients(74.36%) are in the 5th group. and 15 patients are in the 6th group among the total 195 sample patients. 3. The direct nursing care hours for the 4th, 5th, and 6th patient classification system groups are found to be 381 minuites. 483 minuites, and 519 minuites, respectively, which shows that the nursing care hours increases as the dependency of nursing is intensified. The indirect nursing care hours are found to be 454 minuites(7.57 hours). The total mean nursing care hours, which is the sum of the direct nursing care hours(467 min.: 7.78 hours) and the indirect nursing care hours (454 min.: 7.57 hours), is 921 minuites(15.35 hours) per patient a day. 4. The nursing care cost is calculated to be 123,297 won per patient a day. Considering the average duration in the ICU, we can find the total nursing care cost is 610,318 won.

This study was designed to adapt the Turkish versions of scales to evaluate fatigue in children with cancer from the perspectives of the children, parents and staff. The objective of this study was to validate "Child Fatigue Scale-24 hours" (CFS-24 hours), "Parent Fatigue Scale-24 hours" (PFS-24 hours) and "Staff Fatigue Scale-24 hours" (SFS-24 hours) for use in Turkish clinical research settings. Translation of the scales into Turkish and validity and reliability tests were performed. The validity of the translated scales was assessed with language validity and content validity. The reliability of the translated scales was assessed with internal consistency. The scales were evaluated by considering the following: calculation of the Cronbach alpha coefficient for parallel form reliability with 52 pediatric cancer patients, 86 parents and 43 nurses. The internal consistency was estimated as 0.88 for the Child Fatigue Scale-24 hours, 0.77 for the Parent Fatigue Scale-24 hours, and 0.72 for the Staff Fatigue Scale-24 hours (Cronbach's ${\alpha}$). The Turkish version of the Child Fatigue Scale -24 hours, the Parent Fatigue Scale -24 hours and the Staff Fatigue Scale -24 hours were judged reliable and valid instruments to assess fatigue in children and showed good psychometric properties. These scales should assist in understanding to what extent initiatives can minimize or eliminate fatigue. Our scales are recommended for further studies and use in pediatric oncology clinics as routine measurements and nursing initiatives should be planned accordingly.
