공기조화기는 건물내에서 일하는 사람의 공기환경을 좋게 하기 위한 시설로서 실내작업자와는 밀접한 관계가 있다. 공기환경에서는 공기의 온도, 습도와 풍속유지 범위를 정하고 탄산가스, 일산화탄소 및 부유먼지 함유량을 규제하고 있다. 더욱 정기적 측정을 하여 그 기록을 보관해야 한다. 이상과 같이 실내환경에 대한 감시가 엄격해짐으로 실내환경에 신경을 써야 할 것이다. 이런 문제 때문에 공기기술자라 할지라도 공기조화기의 기능을 어느정도 이해해 둘 필요가 있다, 그래서 2회에 걸쳐 공기조화기의 기초지식과 실무 주안점을 소개할까 한다.

Some OECD countries are showing signs of decoupling in the transportation sector. In terms of sustainable development, the decoupling of economic activities and greenhouse gas emissions in the transportation sector is very important. This study calculated a decoupling index of greenhouse gas emissions in the transportation sector for 25 OECD countries. Also this study analyzed the impact of energy transition on decoupling regimes. According to the analysis, a considerable number of countries have reached the decoupling phase, and some countries have shown strong decoupling regime in which greenhouse gas emissions are reduced despite economic growth. From ordered panel logit analysis, energy transition had significant impact on achieving decoupling phase. Electrification of transport had a positive effect on the decoupling, while the gasification was not significant. In addition, small traffic, high urbanization rates, strong environmental policies, and high trade opening have had significant effects on achieving decoupling.

Objective: The main purpose of this study was examine the relationships among goodness of fit between mother and child, child's self-esteem and quality of home environment. Also, the moderating effects of quality of home environment among preschoolers were investigated in the relation of interest in this study. Methods: The study subjects were 195 children who attended preschools, located in Seoul. The preschoolers' self-esteem was tested by the trained researcher, and both of levels of goodness of fit between the mother-child and quality of home environment were rated by the mothers of this study. Results: The main results of this study found that levels of preschoolers' self-esteem were positively related to goodness of fit between the mother-child, and quality of home environment. Furthermore, the effects of goodness of fit between mother-child on preschoolers' cognitive, physical, and emotional self-esteem were moderated by the quality of home environment. Conclusion/Implications: Along with those findings, implications for research and practice were discussed.
