This empirical study focused on examining the relationship between transactional transformational leadership style and power of construction project manager and the organizational effectiveness, respectively, and the moderating role of power between leadership and the organizational effectiveness. A 790 numbers useful questionnaires were obtained from the stuffs working at the construction sites excluding project managers. Internal consistency test using Cronbach's ${\alpha}$ and confirmatory factor analysis were conducted for the reliability and validity of the scales respectively. And cluster analysis and multivariate analysis of variance (MANOVA) were conducted to test the hypotheses. The results and implications are as follows. First, the leadership styles of project managers influence positively the subordinates' job satisfaction but not organizational commitment in construction project. Second, the power styles of project managers influence positively the subordinates' job satisfaction and organizational commitment. Third, the leadership styles of the project managers influence positively the subordinates' job satisfaction and organizational commitment by the power moderating role. The implication of this result is important because of the fact that the transformational leadership can be useful even in the construction projects. And the moderating role of the project manage's power suggests.

This study, with reference to data on economic conditions in Shandong Province, China, looked into trade and investment activities in Korea and major cities of Shandong - Qingdao, Yantai, Weihai and Jinan - and investigated claim cases between the two countries by type. In addition, we investigated the matter empirically by conducting a survey administered to 300 Korean companies investing in Shandong Province and, based on the data, tested hypotheses for inferential analysis. The findings are as follows: i) while hypotheses in which the size of a firm, represented by import and export volume, has a positive relation with the frequency of trade claim filings (H1) and with the financial value of the trade claims (H2) were quoted, company size proved to have a significantly negative relation with the time required to obtain a claim decision, which rejects the third hypothesis (H3) in which the relation was thought to be positive: ii) while products, as represented by the type of business, showed a clearly significant difference with the frequency of trade claim filings (H4) and with methods of preventing and responding to claims (H6), they did not show a significant link to the type of trade claim (H5). This study is a theoretical and empirical overview of Korean companies based in Shandong Province of China, and can be used to address the practical needs of the Korean companies looking to start business in Shandong Province.

The purpose of this study was to investigate the brain activities by 4-types of Generating Process of Scientific Emotion (GPSE) in the hypothesis-generating biological phenomena by using fMRI. Four-types of GPSE were involved in the Basic Generating Process (BGP), Retrospective Generating Process (RGP), Cognitive Generating Process (CGP) and Attributive Generating Process (AGP). For this study, we made an experimental design capable of validating the 4-types of generating process (e.g. BGP, RGP, CGP and AGP), and then measured BOLD signals of 10 pre-service teachers' brain activities by 3.0T fMRI system. Subjects were 10 healthy females majoring in biology education. As a result, there were clear differences among 4-types of GPSE. Brain areas activated by BGP were at right occipital lobe (BA 17), at left thalamus and left parahippocampal gyrus, while in the case of RGP, at left superior parietal lobe (BA 8, 9), at left pulvinar and left globus pallidus were activated. Brain areas activated by CGP were the right posterior cingulate and left medial frontal gyrus (BA 6). In the case of AGP, the most distinctively activated brain areas were the right medial frontal gyrus (BA 8) and left inferior parietal lobule (BA 40). These results would mean that each of the 4-types of GPSE has a specific neural networks in the brain, respectively. Furthermore, it would provide the basis of brain-based learning in science education.

주거환경에서 거주자의 '시각만족(residents' satisfaction with visual appearance)은 더 큰 추상적 개념인 '주거만족'(residents' housing satisfaction)과의 밀접한 인과적 관련(Francescato et. al., 1979) 때문뿐만 아니라 인간 기본 욕구 중의 하나인 미적 욕구의 충족과 관련되어 있다는 점(Chin, 1991)에서도 중요시 되어야 할 이론적 개념이다. 본 연구에서는 거주자의 시각만족을 종속지표로 보고, 다양한 영향 가설변수들과의 인과 적 관련도를 경로분석(path analysis)을 통해 검증하고 있으며, 어떤 변수 가 어떤 이유(경로)로 또는 얼마만한 크기로 거주자의 시각만족에 영향을 주는 가가 중점적으로 토의된다. 한국의 6개 대단위 주거단지로부터 다단 계표집 방법과 설문면담 방법을 통해 646명의 응답이 수거되었다. 분석의 첫 단계로써, 다수의 설문문항을 본 연구의 가설 변수로 집약하기 위한 요 인분석(factor analysis)이 사용되었고, 요인 분석으로부터 추출된 변수들간 의 인과적 관련도를 검증하기 위해 최종적으로 경로분석이 사용되었다. 본 연구의 결과를 요약해 볼 때, 본 연구의 가설 변수 대부분이 최종 종속변 수인 거주자의 '시각만족'에 유의한 인과 영향을 보이는 것으로 나타났으 며, 구체적으로 '시각적 무질서'(visual disorder), '시각적 단조로움'(visual monotony), '단지 과밀감'(development crowding) 등이 부정적 영향을, '시 각적 매력'(visual attractiveness)과 '인근 자연녹지의 존재'(presence of nearby natural environment)등이 긍정적 영향을 미치는 것으로 파악되었 다. 그 외에도 '옥외공간이용 편리'(outdoor or recreation convenience)와 ' 이웃만족'(satisfaction with neighbors), 그리고 '주거환경 유형'(building type, building arrangement type)등도 유의한 인과적 관련을 보이므로써, 기존 문헌들이 제시하고 있는 것보다 훨씬 다양한 변수들이 다양한 경로를 통해 거주자 시각만족의 영향인자가 될 수 있는 가능성을 제시하고 있다. 가설 변수의 하나인 '길찾기의 난이 정도'(difficulty of way-finding)와 종 속변수간에 유의한 관련도가 나타나지 않은 이유로 길찾기 변수가 '시각만 족'보다는 거주자의 '안전만족'(safety)과 관련된 변수일 가능성도 아울러 지적되었다. 본 연구의 결과로부터, 주거 계획 및 설계분야 그리고 추후 관 련 연구 분야를 위한 여러 제안들이 제시되었다.

Customers are not merely responders but rather active value creators. As a result most researches related to customer value creation behavior focus on customer participation behavior and interaction between service provider and customer. This study set the research model to examine the correlation between customer to customer interaction, brand attachment and customer value creation behavior. For this study, the relationship among social support, C-to-C social interaction, similarity, brand attachment, and customer value creation behavior were modelled and used to validate our hypotheses. A path model was verified with structural equation modeling using dataset from survey. Results of this study are summarized as follows. First, this study show the C-to-C social interaction, such as social support, C-to-C social interaction, similarity have effects on brand attachment. Thus, this was statistically significant although dismissed from hypothesis verification. Second, the structural correlation shows brand attachment has positive effect on customer value creation behavior The findings suggest that managers need to identify and pay attention to positive customer to customer interaction in the service encounter so that it influence customer brand attachment and customer value creation behavior which is the competitive advantages of service brand.

Information technology (IT) outsourcing is considered an effective strategy to manage and maintain organizational technologies in a rapidly changing business environment. In particular, to meet diverse market needs, many organizations that outsource their IT functions practice a multi-vendor approach as their main outsourcing strategy. Although a few studies have been conducted about the multi-vendor approach, most previous works primarily emphasized conceptual arguments and normative prescriptions. In addition, scant attention has been directed toward the relational structure between the client and multiple vendors in the multi-vendor approach and its implications for outsourcing success. This study proposes a model from the transaction cost perspective by conceptualizing two dominant relational structures of the multi-vendor approach, namely, single-vendor dominant model and the multi-vendor dominant model, and hypothesizing their relationships with two outsourcing outcomes, project success and user satisfaction. The proposed model is examined using the data collected from 246 companies that have implemented multi-vendor outsourcing. As expected, results indicate that the single-vendor dominant model has a more significant impact on project success, whereas the multi-vendor dominant model has a more significant impact on user satisfaction. The study concludes with the theoretical implications and directions for future research.

The purpose of this research is to confirm that how the support type of the assistant teacher changes the students' creativity and self-efficacy in the Robot Education, particularly Robot Edu-Camp. The study objects are 72 elementary students for 8 groups; each group has 9 students, and 4 groups of them have the assistant teachers and others are supported by giving some feedbacks for their questions or some information if they need. The assumption of this study sets up as in the following; there are no differences for the students' creativity and self-efficacy between the supporting of the assistant teachers with making robots and programing together and the giving feedbacks and information if students need. To verify this assumption, we use the nonequivalent control group in the pretest-posttest designs. The result is as in the following. There's no meaningful differences of the students' creativity by the support type of the assistant teachers. But in the self-efficacy, the groups which are giving feedbacks and information if they need have more higher level of achievement than others. The result shows that if the assistant teachers help the students directly, the students' levels of the self-direction, and control are low because they lean on the teachers. This will give you some implications to the follow-up studies about the support type of the assistant teachers in the Robot Education.

The purpose of this empirical study is to examine and explore the relationships between three variables; shipping companies' service quality, customer satisfaction and customer loyalty. Special features of this study could be summarized as following. First, this is empirical study based on market research according to the definition of 'customer' as freight forwarders and actual exporter/importer together contrary to previous studies. Second, to evaluate shipping companies' service quality, 5 components of SERVPERF model was used. Third, to test correlations between 3 variables; service quality, customer satisfactions and customer loyalty, statistical analysis was used with tools of SPSSWIN ver 15.0 and AMOS ver 7.0. For effective study, many thesis have been obtained through literature survey. However, major results were compiled from directly structured questionnaire, which were collected from Korean import/ export companies and freight forwarders.
