본 연구는 한국청소년정책연구원에서 제공하는 한국아동 청소년 패널조사(Korean Children and Youth Panel Survey) 3차년도(2012) 자료를 이용하여, 중학교 3학년 2,040명의 자아존중감이 삶의 만족도에 미치는 영향을 분석하였다. 생태학적 관점에서 삶의 만족도에 대한 영향요인으로 환경특성(부모친밀도, 친구친밀도, 교사친밀도, 학습적응도)과 개인특성을 고려하였다. 개인특성으로서 자아존중감을 긍정적 자아와 부정적 자아에 대한 평가라는 별개의 두 차원으로 구분하였을 때, 삶의 만족도에 대한 영향요인으로서 두 평가 수준의 상호작용 효과가 존재했다. 즉 부정적 자아평가가 삶의 만족도에 미치는 영향은 긍정적 자아평가 수준에 따라 달랐는데, 긍정적 자아를 높이 평가할수록 부정적 자아가 삶의 만족도에 미치는 음(-)의 영향은 감소했다. 또한 부정적 자아평가 수준이 낮을수록 삶의 만족도가 높았지만, 긍정적 자아평가가 상대적으로 낮은 수준에서는 삶의 만족도가 높지 않았다. 이러한 결과는 청소년의 부정적 자아 형성의 문제를 해결하는 것이 긍정적 자아 형성으로 이어지지 않을 수 있으며, 삶의 만족도를 증진시키기 위해서는 부정적 자아 형성의 문제해결을 넘어 긍정적 자아 형성을 위한 방안과 정책들이 모색되어야 한다는 것을 제시한다.

본 연구에서는 <인생나눔교실> 사업 평가를 시행하기 위해 본 사업의 특성을 고려하여 평가지표를 설계하고 이를 사업평가 모형으로 제시하고자 하였다. 이를 위해 평가지표를 개발하고 AHP 분석을 통해 가중치를 설정하였고, 개발한 평가지표를 토대로 현장 평가를 진행하여 <인생나눔교실> 사업을 평가하였다. 그 결과 참여자 영향과 사업 내용의 적정성 지표가 20개의 지표 중에서 가장 높게 나타났다. 그리고 17년 5개 지역주관처의 현장평가를 실시한 결과, 탁월 및 우수 등급이 4개 기관, 보통 등급이 1개 기관으로 나타났다. 본 연구는 <인생나눔교실>의 사업평가 모형을 개발하여 평가를 체계적으로 시행할 수 있는 기반을 구축했다는 점에서 의의가 있다. 그러나 아직 피평가자의 수용성과 효용성에 대해서는 평가지표에 충분하게 담아내지 못했기 때문에 앞으로 이에 대한 보완이 필요하다. 또한 매년 평가 영역과 평가 지표의 가중치를 재설정하여 평가모형을 지속적으로 보완할 필요가 있다.

For the comfortable housing life, comfortable and pleasant urban environment should be created for the people living in house and in city. There are lots of environmental conditions in city affecting house and life. Also most of all the noise pollution have been become major factor that makes people's life uncomfortable. Recently soundscape researches have been performed to create comfortable urban environment and various studies on the evaluation of urban environmental sounds are now undergoing. This study aimed to analyse the subjective characteristics through the subjective evaluation to the sounds measured with physical parameters and eventually to find out alternative evaluation method for urban environmental sounds. Adjectives applied to previous studies were used for the subjective evaluation and sound sources recorded in specific places were presented with picture at the same time. As a result, new physical parameters such as Lmax, Unbiased Annoyance, G, N and EmT have a feasibility to evaluation of urban environment sounds in terms of acoustic comfort.

Evaluation of fatigue strength on the spot welded part is very important for strength design of spot welded steel structures. In this paper, we could get the life cycle of the spot welded part using the lethargy coefficient obtained through the quasi-static tensile shear test for the specimen welded by current 10kA. The reliability evaluation of the life cycle is completed by comparing the life cycle calculated under the constant loading rate with the life cycle obtained by dynamic fatigue test. And then the result calculated by the lethargy coefficient is verified through the lift cycle calculated using the dynamic final tensile stress formula under the increased loading speed. This way can make save the time and cost in processing of predicting the life cycle of a structure.

Hybrid laminated Al/carbon-fiber-reinforced plastic (CFRP) composites are attracting considerable attention from industries such as aerospace and automobiles owing to their excellent specific strength and specific rigidity. However, when this material is used to fabricate high-pressure fuel storage containers subjected to repeated fatigue loads, fatigue life evaluation for the working load is regulated as an important criterion for operational safety and ease of maintenance. Among the existing evaluation methods for these vessels, the burst test and the hydraulic repeat test require expensive facilities. Thus, the present study aims to develop an improved fatigue life test for Al/CFRP laminated hybrid composites. The test specimen was manufactured using a curved mold considering the shape of a type III high-pressure storage container. The strain-life method was used for fatigue life evaluation, and the life was predicted based on the transition life. The results indicate that the more complex the CFRP stacking sequence, the longer is the transition life. This test method is expected to be useful for ensuring the fatigue safety and economy of hybrid laminate composites.

To apply an analysis method of life cycle cost when assessing economics of equipment system, we should basically set up preconditions such as useful life, price escalation rate, interest rate, etc. as well as consider a calculation algorism of source energy and heat source system, which is a complex process for life cycle costing. For this reason, equipment designers tend to plan heat source systems, without a thorough investigation on economics of alternative systems at the pre-design phase. In this process, architectural designers should adopt a proper heat source system, which is one of the most important factors for planning an appropriate architectural design, through a discussion with equipment designers in a short time. In order to offer an evaluation method for equipment designers to analyze economics of an alternative heat source system easily at the pre-design phase, this research would define the simplified economics, evaluation method through analysis of existing papers for economics evaluation, and examine validity through comparison of simplified method values ($LCC_{EC}$) and life cycle costing values ($LCC_{15}$) for six alternative heat source systems.
