전력계통에서 차지하는 원자력발전의 비중이 증가함에 따라 앞으로는 전력의 수요가 적은 시기와 시간 등에는 원전의 출력을 조정할 필요가 있다. 따라서 장래를 대비한 원자력발전소의 출력조정시험이 추진되고 있다. 다음은 최근 일본에서 실시된 출력조정시험의 개요와 그 안전성에 관한 소개이다.

This paper examines whether me effects of product demand shocks on employment are different between unionized and non-unionized firms, using new firm-level longitudinal data in Korea over the period 1997~2004. The estimation result shows that the effects of both negative and positive demand shocks on employment are smaller in unionized firms than in non-unionized firms. The result implies that unions appear to provide their members with job stability in response to negative demand shocks, while playing a very limited role in employment determination in response to positive demand shocks leading to employment expansion.

우리나라 신발산업에서 중요한 위치를 차지하고 있는 부산 신발산업의 재구조화 과정을 도입기, 대량생산기지로서의 성장기, 구조 조정기, 네트워크 생산체제의 정착기 등 네시기로 구분하고 시기별 특성을 요약하면 다음과 같다. 첫 번째 시기는 1920년대 신발산업이 부산에 도입된 이후부터 1960년대까지이다. 이 시기의 주요 생산품은 고무신류이며, 소수의 대기업에서 대량의 저임금 남녀노동력을 고용하여 기업조직 내에서 일괄대량생산이 이루어졌다. (중략)

The purpose of this study is to help a recovery of fatigue through the effect of cold immersion treatment after rowing ergometer on blood fatigue substance, MDA and SOD in rowing athletes. For this, 10 subjects participated in this study and we divided them into cold water immersion group (CWI, n=10), non-cold immersion group (NCI, n=10). The exercise program was performed to 2000 m rowing ergometer for maintaining high intensity. The data was collected with regard to the interaction effect of the group and time among the CWI and NCI, ANOVA was used. As the post-hoc test, Bonferroni test was used. The significance was set at .05 and the following conclusions were deduced. For lactic acid, there were the main effect of time (p<.001) and significant difference in the both group (p<.001). Also, LDH were significant difference in the each group (p<.05). For MDA, there were the interaction between group and time (p<.05) and the main effect of group (p<.05) and time (p<.001). SOD were indicated main effect of group and time (p<.05), there was significant difference between each group in the after 30 min recovery (p<.05). Collectively, The results of this study suggest that positive effect on blood fatigue substances, reactive oxygen species and anti-oxidation enzyme through cold water immersion intervention. Therefore, we strongly recommend that performing the cold immersion intervention would be beneficial after high intervention exercise.

A construction project with a total construction cost of over 10 billion KRW should be evaluated whether construction works are appropriately executed. The evaluation is carried out on quality management, process management, construction management, safety management, environmental management. The implementation period is within 60 days after completion of construction of the construction, from the time when the construction rate of the construction work has progressed by more than 90% to the construction cost. However, the participating construction engineers should prepare the evaluation within the period according to the evaluation criteria, but there are difficulties in preparation for the evaluation due to the reasons such as the change of engineers in charge and loss of data. Therefore, this study proposes the procedure of construction evaluation and adjusts timing of construction evaluation.

According to Korean pharmaceutic law, spectacles is a kind of medical device or instrument that is composed of a front and two temples with a pair of lenses. If the spectacle is not worn, it is a kind of optical device, but if it were worn, it will makes a new optical system to correct ametropia. Therefore, spectacles must be carried on by dispensing opticians.
