PURPOSES: Regional offices of the Ministry of Land, Transport and Maritime Affairs use a computerized system called KAMIS so as to manage road equipment systematically. Road agencies can record number of operating days by equipment, actual working hours, accumulated operating hours (or distance) by equipment, and operating cost. However, KAMIS does not provide critical information, although it is strongly related to efficient road management equipment operation. In other words, road agencies do not know whether they have sufficient equipment to handle their actual work. METHODS: Therefore, this study suggests a methodology to evaluate for operational efficiency of road management equipment using analytical hierarchy process(AHP). First of all, estimated weights related criteria can be produced by AHP, and then use operational history by pieces of equipment. RESULTS: Results show that importance of management work can differ from weather conditions through five areas. CONCLUSIONS: Commonly, this results can imply to help save money for the purchase and maintenance of road management equipment, and they would improve the functional performance of KAMIS.

It is not stipulated concretely in the Food Sanitation Act what the standardized school food service dieticians indices and the dietician's duties and task elements should be. Therefore, this study was required. The specific purposes of this study were : a) to define the school food service dietician's duties and task elements, b) to estimate the performance frequency and work hours of the dietician's duties and task elements c) to investigate the job specification of the dietician over school food services, d) to develop the standardized indices of the dietician needed in school food service operation. For this study, school food service dietician's work functions were defined in 10 duties and 60 task elements based on the studies precedented and literature review and pilot test process. This study was conducted in school food service systems nationwide using written questionnaire and interview with the official in charge and delphi technique. The questionnaires were mailed to the dieticians of three types of school food service systems. Of the 660 schools that participated in this study, the 624 responses were selected for analysis. Statistical analyses were performed with SAS/Win 6.12 program so as to provide a descriptive statistics, T-test, ANOVA. The main results of this study could be summarized as follows: A characteristic common to all the school food service systems was that 'cooking and distribution management' took the longest hours of work, while 'nutrition education' took the shortest hours of work. The standardized index of dietician over school food service was one person in conventional system independently of the number of meals per day. In the commissary system, according to the numbers of meals served per day, it was 0.95-1.38 persons and 1.27-1.55 persons and 1.40-1.91 persons. In joint management system, the standardized index was 1.03-1.42 persons in case of serving less than 700 meals per day.

purpose of this study was to compare the direction of work-family balance policy with the family support of Chosun Dynasty by reviewing the literature of the period, including diaries of "Soemilok" and "Miamilki" and letters written by Yangban. The major findings drawn from the literature were as follows: The husbands in Chosen, especially as public officials, were under strong obligation to support their family like working wives in modern society. They were able to care for and support their families and maintain their careers due to flexibility in their office hours. They had dual burdens of home management and outside labor but their requests for the necessities of life were resolved promptly in public offices. From this result, it was argued that the policy for dual burden for women would benefit from a consideration for flexibility and reduction of working hours. Especially it was emphasized that the border between home and work place should be more open and the relationship of family should be supported by work-family balance policy.

Background: As social distancing persists and interest in work-life balance grows, more companies are adopting flexible work policies. While there have been studies on sleep disorders associated with different types of work, such as shift work, research exploring the relationship between flexible work schedules and sleep disorders is still limited, particularly among Korean workers. Methods: We performed a secondary analysis of the 6th Korean Working Conditions Survey, focusing on 31,243 paid workers out of a total of 50,538 participants. We defined flexible workers as those who set their own working hours. Sleep disorders were divided into three categories: 'difficulty falling asleep,' 'frequent waking during sleep,' and 'waking up feeling exhausted and fatigued.' Using scores derived from three specific symptoms, the Minimal Insomnia Symptoms Scale (MISS) was calculated to assess the prevalence of insomnia. We used chi-square tests to analyze demographic and job-related differences. A multivariate logistic regression analysis was employed to identify any relationship between flexible work schedules and sleep disorders. Results: Significant differences were found between flexible and non-flexible workers regarding age, income level, education level, and job type. Flexible workers reported sleep-related symptoms significantly more often. The odds ratio for insomnia was 1.40 (95% CI 1.21-1.61). For males, the odds ratio was 1.68 (1.36-2.08). Conclusion: This study establishes a correlation between flexible work schedules and sleep disorders among Korean salaried workers. Potential causes could include changes in circadian rhythm, increased work demands, and extended working hours. To precisely determine causality and associated diseases, further research is required.

현대의 산업자본주의는 근로의 제공과 임금의 수령이라는 관계가 사회를 규율하는 중요한 원리로 자리 잡고 있다. 근로계약에 따라 자신의 노동력에 대한 처분권을 사용자에게 맡기고 제공받는 임금은 직접적인 보상이 되고 있으며, 적절한 휴식의 보장으로 인간다운 삶의 보장과 재생산을 할 수 있어야 한다. 자유계약에 의한 근로관계의 구축은 근로자 보호에 문제점을 나타내고 있으며, 이에 따라 근로자에 대한 최소한의 권리로 근로시간의 최대치를 정하고 최소휴식의 기준을 설정·부여하고 있다. 근로시간의 단축은 근로자의 삶의 질이라는 측면에서 매우 중요하지만 효율적인 기업활동에 있어서도 중요한 문제이다. 우리나라는 2020년 기준 연간 근로시간이 1,908시간으로 장시간 근로를 하고 있으며, UN산하 자문기구인 지속가능발전해법네트워크(SDSN)가 조사한 행복지수에서 OECD 37개국 중에서 하위 3번째로 나타나고 있다. 이에 따라 근로시간 단축의 필요성은 인정되어, 2018년부터 1주의 최대 근로시간이 52시간으로 제한하고 있다. 이러한 상황에서 기업의 부가가치 창출력을 유지하고, 근로자의 다양한 니즈에 부응하기 위한 방안으로 법적으로 다양한 근로시간의 예외를 두고 있으며, 우리나라 근로기준법은 3개월 이내의 탄력적 근로시간제와 3개월을 초과하는 탄력적 근로시간제, 선택적 근로시간제와 근로시간의 연장을 허용하는 연장근로의 제한을 두어 이를 허용하고 있다. 하지만 2021년 개정된 탄력적 근로시간제를 적용하는 것과 최근 논의되고 있는 정산 단위기간의 확대에 대한 논의에서 탄력적 근로시간제의 문제점이 있어 이에 대한 개선이 필요하다. 따라서 본 논문은 탄력적 근로시간제의 문제점과 이에 때한 개선방안을 살펴보고자 한다. 탄력적 근로시간제는 미리정한 기준에 따라 특정일 또는 특정주에 법정근로시간을 초과하더라도 근로기준법에서 정하고 있는 근로시간에 위배되는 것이 아님과 동시에 초과한 연장근로에 대한 가산임금을 지급하지 않아도 되는 제도로 주로 계절별 시기별 업무량 편차가 심한 제조업, 판매서비스업, 연속사업이나 장기간 조업을 위한 전기·가스·수도, 운수업 등에 있어 교대근무형태로 유용하게 활용되고 있으며, 운용에 따라 보다 짧은 근무일 설정을 통한 휴일 확대 등 근로시간 단축의 방편으로 활용되기도 한다. 하지만 정산 단위기간을 확대할 경우 근로자가 수령할 수 있는 가산임금을 수령하지 못하게 되어 근로자에게 불리하다. 따라서 첫째, 현재 논의되고 있는 정산 단위기간 확대를 하려면 현행 기준에서 확대되는 기간에 대하여 추가임금 지급을 하도록 하여야 한다. 둘째, 탄력적 근로시간제의 개별근로자에 대한 적용을 개선하여 근로자대표와의 서면합의에 있어 개별근로자와 충분한 협의를 하도록 하는 조치가 필요하고, 셋째, 정산 단위기간 동안 연장 근로의 허용시간을 명확히 하여야 하며, 넷째, 1일 최대근로시간이 정해지지 않고 있어 근로시간의 한도를 최대 근로시간으로 제한하거나 연속휴식에 대한 적용이 필요하며, 추가적으로 근로자대표의 서면합의가 탄력적 근로시간제의 적용에 있어 중요한 문제이므로 근로자대표의 대표성을 확보하여야 할 것이다.

Background: Osteoarthritis of the knee is considered to be related to knee straining activities at work. The objective of this review is to assess the exposure dose-response relation between kneeling or squatting, lifting, and climbing stairs at work, and knee osteoarthritis. Methods: We included cohort and case-control studies. For each study that reported enough data, we calculated the odds ratio (OR) per 5,000 hours of cumulative kneeling and per 100,000 kg of cumulative lifting. We pooled these incremental ORs in a random effects meta-analysis. Results: We included 15 studies (2 cohort and 13 case-control studies) of which nine assessed risks in more than two exposure categories. We considered all but one study at high risk of bias. The incremental OR per 5,000 hours of kneeling was 1.26 (95% confidence interval 1.17-1.35, 5 studies, moderate quality evidence) for a log-linear exposure dose-response model. For lifting, there was no exposure dose-response per 100,000 kg of lifetime lifting (OR 1.00, 95% confidence interval 1.00-1.01). For climbing, an exposure dose-response could not be calculated. Conclusion: There is moderate quality evidence that longer cumulative exposure to kneeling or squatting at work leads to a higher risk of osteoarthritis of the knee. For other exposure, there was no exposure dose-response or there were insufficient data to establish this. More reliable exposure measurements would increase the quality of the evidence.

Purpose: This study was conducted to provide baseline data to develop work patterns for nurses that are suitable to Korean hospitals. Shift work patterns and nurses' preferences for working condition were examined. Methods: Questionnaires for nurse departments and nurses were mailed to 478 hospitals from June 1 to July 30, 2012. Nurse departments of 174 hospitals and 1,409 nurses responded to the questionnaire. Data were analyzed using SPSS statistical program. Results: Of the nurses, 89.4% were working three shifts. Of the hospitals, 17.3% had implemented fixed night work. Although 80% of nurses preferred fixed time work, only 24.9% of hospitals had fixed working hours. Of the nurses, 57% agreed with night work as fixed but potential night nurses accounted for only 17% of the respondents. Sixty-three percent of the nurses agreed on short time work during busy hours. There were preference differences according to age, marital status and clinical career. Conclusion: As many nurses reported a preference for various flexible working patterns rather than three shift work, there is a need for new decisions on hospital policy to ensure improved working conditions for nurses and enhanced job security. Legal requirements also need to be considered for various work patterns.
