An inducer is forward-attached to an impeller to improve the suction performance. This paper described the experimental and numerical investigations on the concept of NPSH similarity about the inducer scale. As Reynolds number decreased for the same scale inducer, the hydraulic performance is slightly reduced because of the viscosity. The suction performance similarity is in good agreement. For different scale inducers, the NPSH similarity did not follow the conventional rule which is proportional to the square of the inducer diameter. A cavity of two times scale inducer grows faster under cavitation inception, and the head is more drop as the fluid passes blades. Because of the simplified cavitation model and vapor pressure, the NPSH similarity dose not have an accuracy. This study suggested an empirical formula for the NPSH similarity.

수준 높은 공공서비스를 제공받고자 하는 국민의 권리의식이 향상되고 정보기술의 급속한 발전에 따라 고객의 요구사항이 다양하다. 신속하고 정확한 상담의 서비스를 제공하기 위한 수단으로서 콜센터에 대한 필요성이 높아지고 있다. 공공기관의 고객접점인 콜센터에서 근무하는 상담원들의 직무특성과 직무태도를 통하여 직무만족과 이직의도에 대한 상관관계를 분석하고자 한다. 이직의도를 낮추기 위해서는 상사의 관심과 지원이 중요한 요소로 나타났다. 본 연구의 의의는 고객접점을 운영함에 있어서 직무상 발생하는 스트레스를 효율적으로 관리하여 상담원의 직무만족을 증대시켜 이직의도를 낮추는데 기여하고자 한다.

보성군에서 수집한 민요들의 의식·노동·유희요(謠) 별(別)로 정리하였다. 의식요(儀式謠)로는 걸메당·상여·독경(讀經)소리가 실렸다. 전래(傳來) 혼인식(式)에 있어서의 가마소리인 걸메당소리는 전국의 몇 곳에서만이 가창자가 남아 있는 희요(稀謠)이다. 상여소리(처음에 운구 들어 울릴때의 긴소리, 길 갈 때의 가난보살과 어가리넘자, 비탈길 오를 때의 나무아미타불, 달구소리)는 전남지방에 널리 전파되어 있는 것과 동계(同系)이다. 노동요(謠)는 주로 농요(農謠)<광의(廣義)>가 수집되었다. 소동패전갈을 수록하였다. 모심기곡(曲)은 공(共)히 일반 농부가 쪼임에 비하여 모찌기와 논매기곡(曲)(<표2>참조)은 다양성을 띄웠다. 산아지로고나곡(曲)은 전(全) 면(面)에 두루 퍼져 있으며 논맬 때, 장원질소리, 소동패노래에도 쓰인다. 산떨이(올라간다)는 고흥군의 것과 같다. 터 다지는 노래로는 얼럴럴 상사도야를, 상량노래로는 어유아 상량이야를 부른다. 줄메고 나가는 노래의 받음구는 위야허허 또는 상사뒤여뒤여(회촌면)이다. 유희요(謠)는 남사당의 덜미 (꼭두각시극)노래인 떼루와 제나난실을 싣고 그 위에 치마·줌치·사위·강도령·이노래 등을 실었다.

The Employment Permit System (EPS), a system of bringing in low-skilled foreign workers, has been implemented since 2004 to relieve labor shortages in SMEs. Despite the increasing number of foreign workers under this system, due to lack of research we have very limited managerial understanding. Moreover, previous studies focused on economic or legal perspectives, which calls for a different perspective of business and management. In this study, we examined how to foster organizational citizenship behaviors (OCB) of low-skilled immigrant workers at the workplace by integrating two analytical frames-social support from management studies and cultural adjustment from immigrant literature. We tested our model using a sample of 661 immigrant workers from 11 countries working in Korea. Our results indicated that, social support perception triggered not only a direct effect on organizational citizenship behaviors of immigrant workers but also indirect effects via the level of cultural adaptation. Our findings indicated that two views are all meaningful in explaining OCB of immigrants, and provided practical implications to SMEs using EPS.

The purpose of this study is to examine the effects of the perception of compensation equity on the organizational commitment, and the potential mediating roles of trust in that process. The results were as follows; First, the perception of compensation equity(pay and promotion equity) has a positive influence on organizational commitment. Second, hierarchical regression showed that promotion equity added to pay equity in expanding the variance of the organizational commitment. Third, according to results of regression analysis was found for mediating role of trust in their leaders in the relationships between compensation equity and organizational commitment. The result of the study implies that trust is a crucial factor in the explanation of organizational commitment and hotel managers are able to motivate organizational commitment by paying more attentions to trust in their leaders.
