Aluminum alloys have been considered for substantial use in these industries. This ensues from their attractive strength to weight ratio, superb formability, apposite weldability and acceptable corrosion resistance. Depending on the specific application, corrosion behavior is a significant factor of a welded joint. In this study, recent researches in the view of corrosion resistance of friction stir welded aluminum alloys are briefly reviewed.

Ferritic stainless steels are widely used in the construction industry and in exhaust manifolds due to their low cost and relatively superior stress corrosion cracking resistance and pitting corrosion resistance compared to austenite stainless steels. Ferritic stainless steels are currently welded by various welding process including gas tungsten arc welding (GTAW), electron resistance welding (ERW) and laser beam welding. However, when these stainless steels are welded by fusion welding, some problems occur in the fusion zone (FZ) and heat affected zone (HAZ). First, the ductility of the weld is reduced due to the grain growth in the FZ and HAZ. Second, as its HAZ is frequently sensitized during welding, corrosion resistance deteriorates in this region due to the Cr depletion zone. To prevent these problems, it is recommended that ferritic stainless steels be welded with a low heat input. In this study, recent researches in the view of friction stir welded ferritic stainless steels are briefly reviewed.

The purpose of this study is to verify the structural relationships between leisure competence fun factor and leisure satisfaction in marin sports participants. To achieve the objective of this study, 387 surveys were collected from marin sports participants in Seoul, Gyeong-gi, and Chung-cheung areas. Frequency, reliability, correlation, confirmatory factor analysis, and structural equation modeling were using SPSS 18.0 and AMOS 18.0. The significance level of all tests was p<.05. The findings were as follows: First, leisure competence had a positive influence on fun factor. Second, leisure competence had a positive influence on leisure satisfaction. Finally, fun factor had a negative influence on leisure satisfaction. Marin sports offered high satisfaction to participants. However, competence, fun factor, and nature of participants and environment did not influence on satisfaction. Therefore, we need to develop many teaching methods and infra for high satisfaction among marin sport activity.

본 연구의 목적은 여가활동 참여자의 여가태도, 몰입, 만족 및 재 참가 간의 관계를 검증하는 데 있다. 본 연구의 대상자는 서울, 경기, 충청도에서 여가활동에(스포츠, 교양, 관람, 사교, 여행, 오락) 참여하는 성인남녀를 편의표본 표집법을 이용하여 총 332명을 조사하였다. 자료처리로는 SPSS 18.0을 이용하여 빈도분석, 신뢰도분석, 상관관계를 분석하였고, AMOS 18.0을 이용하여 확인적 요인분석, 구조모형방정식(SEM)을 실시하였다. 이상의 연구방법을 진행하여 얻어진 결과는 다음과 같다. 첫째, 여가활동 참여자의 여가태도는 여가몰입에 긍정적인 영향을 미쳤다. 둘째, 여가활동 참여자의 여가태도는 여가만족에 긍정적인 영향을 미쳤다. 셋째, 여가활동 참여자의 여가태도는 재 참가에 부정적인 영향을 미쳤다. 넷째, 레저스포츠 참여자의 여가몰입은 재 참가에 긍정적인 영향을 미쳤다. 다섯째, 여가활동 참여자의 여가만족은 재 참가에 긍정적인 영향을 미쳤다. The purpose of this study was to examine the relationships between leisure attitude, flow, satisfaction, and re-participant in leisure activity. To achieve the goal of this study, a total of 332 surveys collected from sports, hobby, watch, social, tour, game activity participants were utilized for analyzing. Frequency, reliability, confirmatory factor analysis, and structural equation modeling were conducted using SPSS 18.0 and AMOS 18.0. Main findings were as follows; First, leisure attitude had a positive effect on leisure flow, Second, leisure attitude had a positive effect on leisure satisfaction, Third leisure attitude did not have influence on re-participant. Fourth, leisure flow had a positive effect satisfaction. Finally, leisure satisfaction had a positive influence on re-participant.
