  • The purpose of this study is to analyze the correlation between the stature and the muscle performance ratings and the subjective discomfort rations at performing lower arm's pronation and supination according to change sin the height of working table for more efficient performance at designing a working table and performing a work. For the purpose, this study conducted an experiment targeting 40 people in their 20s, who were classified into 4 groups each group composing 10 people at intervals of 5cm from the standard stature of 166.5cm. The experiment measured the maximum isometric pronation and the supination muscular power, and at measuring the factors, the heights of working tables were set as 800mm, 850mm, and 900mm. From the measurement results, it was found that the stature and the maximum muscular power was correlated. That is, as the experiment groups's average stature is higher, the maximum muscular power was higher. For the correlation between the motion patterns(pronation and supination) and the maximum muscular power, it was seen that the maximum muscular power was higher at performing the pronation than the supination. In the correlation between motion patterns and the subjective discomfort ratings, it was seen that the subjective discomfort rating was higher at performing the supination than the pronation. For the correlation between height adjustment and the subjective discomfort ratings, as the height of working table was lower, the subject discomfort rating was lower. Therefore there was no difference in the maximum muscular power according to the height changes of working table, but it was found that as the working table was higher, the user felt more comfortable.

  • Marking is a process that engraves letters or a pattern onto the surface of sheet metal. During marking, it is important to set the proper working conditions for clarity of the letters. In this study a simple case for forming circular protrusions by half-piercing and embossing was initially attempted to determine the working conditions which gave good results with respect to shape accuracy. Corner-radius and flatness of circular protrusions made under several experimental conditions were measured and compared. It is shown that the precision of protrusions by half-piercing is superior to that of embossing, and the clearance between punch and die exerts a strong influence on the shape accuracy rather than the penetration percentage into the thickness of the sheet metal. The marking dies for "SNUT" letters, as an example, by applying the above results were manufactured with four different clearances. The working variables for the experiment were clearance and marking depth. For the very shallow depth of 0.1mm the letters were not clearly read. Letters marked under other conditions were easily distinguished with increasing marking depth. It was confirmed that the half-piercing technique with proper values of the working variables gives good quality for the marking of sheet metal.

  • Between 1920 and 1996, a total of 39 Conventions, 29 Recommendations and one Protocol were adopted by the International Labour conference. But Many ILO Instruments were outdated, deficient and not reflective of modern practice, many contained technical detail which discouraged ratification and were thus ineffective. However, many issues which had become relevant were not covered by existing instruments. Therefore, the Governing Body of ILO, at its 262nd Session(March-April 1995), decided to set up a Working Party on Policy regarding the Revision of Standards. It was decided that the Working Party would examine the need for revision of all maritime Conventions and Recommendations adopted before 1985 with a view to rejuvenating and strengthening the standard-setting system. The Working Party initiated its examination of maritime instruments during 273rd Session(November 1998) of the Governing Body. The review made by the Working Party has concluded that of the maritime Conventions examined, seven of them are obsolete and should be revised, 13 should be denounced and six were considered either up to date or were identified for promotion, most of which were approved by the Governing Body. The consolidated maritime labour convention will be adopted in February 2006.

  • Purpose: The purpose of this study was to investigate the relationships between psychosocial working conditions and psychological well-being depending on the gender among Korean interactive service workers. Methods: This study was a secondary analysis of the data extracted from the 2011 Korean Working Conditions Survey. For the present analysis, 15,669 workers who interact with others at work were selected. Based on the existing literature, a set of variables was chosen from the KWCS. Psychological well-being was measured using the WHO-5 well-being index. Results: The prevalence of poor psychological well-being was significantly higher among men (43.1%) than women (39.6%). Women were more likely to be exposed to demands for hiding emotions, bullying, and discrimination, whereas men were more likely to be exposed to psychological job demands, cognitive demands, demands for responsibility, role conflict and long working hours. Most factors were associated with poor well-being among women and men except demands for hiding emotions, skill discretion and development, physical violence, and sexual harassment. Conclusion: Based on these results, some practical suggestions are offered to help interactive service workers adjust to their duties.

  • 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.
