Purpose: This study was done to develop and test a structural model on smoking cessation intention in technical high school men. The conceptual model was based on the theory of reasoned action and health promotion model. Methods: From May 29 to April 13, 2015, 413 technical high school students who smoked completed a structured questionnaire. Data were analyzed to calculate the direct and indirect effects of factors affecting smoking cessation intention. The SPSS WIN 20.0 and AMOS 21.0 programs were used. Results: The hypothetical model was a good fit for the data. The model fit indices were $x^2/df=2.36$, GFI=.95, AGFI=.92, NFI=0.97, and RMSEA=.05. Self-esteem had direct and indirect effects on smoking cessation intention. Attitude, subjective norm, and self-efficacy had direct effects on smoking cessation intention. Smoking knowledge and environmental factor had indirect effects on smoking cessation intention. This model explained 87.0% of the variance in smoking cessation intention. Conclusion: These results indicate that technical high school students' intention to stop smoking can be improved through an increase in self-esteem, negative environmental factors, attitude toward smoking cessation, subjective norm about smoking cessation, and self-efficacy for smoking cessation.

The main propose of this research is to examine the performances in ERP introduced enterprises by utilizing BSC model proposed by Kaplan and Norton [1992], to realize this goals, a theoretical review on ERP, BSC, and other related issues is performed in advance, accordingly, research model was generated. In conceptual model analysis, we focused on casual relationships among four performance measurement indicators after introduction of ERP proposed by Kaplan and Norton [2000]. To test the model, structural equation modeling is employed to analyze data collected from 164 enterprises which have introduced ERP for more than 1 year. Survey respondents were confined within the representatives of each enterprise's ERP. Hypotheses proposed in our research are tested by covariance structure model, results are listed as follow : First, learning and growth performance is significant factors for improving both internal process performance and customer performance; second, process performance has a positive impact on customer performance third, despite that customer performance is positively related to financial performance, no direct relationship is found between internal process performance and financial performance, an indirect relationship is built through intermediate medium of customer performance. Based upon these results, we discuss implications at the latter part of paper. Meanwhile, we also provide research limitations, and future research in the final section.

건축, 토목기술의 발달과 토지의 효율적 이용 요구 증가로 인해 인간의 생활공간은 지표에서 지상, 지하로 확대되었다. 기존의 2차원 지적 시스템으로는 관리의 한계성이 있기에 이런 현실을 효과적으로 반영할 수 있는 3차원 지적 시스템의 필요성이 제기되었다. 이 연구에서는 3차원 지적 시스템의 구성요소와 개념적 데이터 모델들을 소개하고 현 상황을 반영한 효율적인 개념적 데이터 모델을 제시한다.

본 연구에서는 홍수시 다목적댐의 효율적 운영을 위하여 상류로부터 유입되는 홍수유입량을 실시간으로 예측하기 위해 역전파 신경망 모형을 사용하여 댐유입량 예측모형(Neural Dam Inflow Forecasting Model; NDIFM)을 개발하였다. NDIFM은 다목적댐에 의한 하류의 홍수조절 비중이 큰 낙동강의 남강댐 유역에 적용하였으며, 입력자료로는 댐유역 평균강우량, 실측 댐유입량, 예측 댐유입량 통을 사용하여 실시간 댐유입량 예측의 가능성을 검토하였다. 실측치와 예측치를 비교ㆍ검토한 결과 제시한 세 가지 모형 중 NDIFM-I이 가장 우수한 결과를 나타내었으며, NDIFM-II 및 NDIFM-III 또한 다양한 예측가능성을 보여주었다. 따라서, 강우-유출의 비선형시스템 모의를 위하여 물리적 매개변수가 복잡한 개념적 모형보다는 양질의 수문관측 자료만 축적된다면 블랙박스 모형인 신경망 모형이 실시간 홍수예측에 효율적으로 활용될 수 있을 것이다.

Time series of spring discharge data in Jeju island can provide abundant information on the spatial groundwater system. In this study, the classification based on time series of spring discharge was performed with clustering analysis: discharge rate and EC. Peak discharges are mainly observed in august or september. However, double peaks and late peaks of discharge are also observed at a plenty of springs. Based on results of clustering analysis, it can be deduced that GH model is not appropriate for the conceptual model of Groundwater system in Jeju island. EC distributions in dry season are also support the conclusion.

Nowadays, multimedia and Hypermedia become hot topics in information industry. Due to high capacity of media storage and fast communication network, it is possible to exchange text data as well as image, moving picture and voice. Especially to apply hypermedia under CALS standard environment, the relation between international standard and CALS standard needs to be considered. This study introduces conceptual background and processing model of HyTime (Hypermedia Time-based Structuring Language) which is a specification of hypermedia exchange, Hyper ODA (Hyper Open Document Architecture) which is a major multimedia communication basis, MMCF (Multimedia Communication Forum), AHM(Amsterdam Hypermedia Model), and DSRM(DAVIC System Reference Model) reference model which helps determination of hypermedia communication specification Although they are international standard, provisional standard or non-standard, it discusses the Possibility of adopting them as CALS standard. Hence, this paper chooses the best recommend for CALS among these models.

The purpose of this study is to develop a model of adolescent's conspicuous consumption on clothes. For this study, questionnaires were administered to 400 adolescents in Kwang-Ju. Employing a sample of 283, data were analyzed by using the structural equation model of the Lisrel analysis, in addition to cronbach's alpha coefficient for reliability and confirmatory factor analysis for validity. The results of this study was found that a conceptual model for adolescent's conspicuous consumption on clothes was judged to provide acceptable goodness of fit. Specifically, materialism and clothing conformity had a direct effect on conspicuous consumption on clothes, and materialism, hedonic shopping orientation and clothing interests had a indirect effect on conspicuous consumption on clothes. The results indicated that clothing conformity had important influence on conspicuous consumption and its influence on adolescent's conspicuous consumption was mediated by materialism, hedonic shipping orientation and clothing interests.

As the digital economy goes global, firms are trying to find suppliers that can address their managerial goals and strategies. The alternatives are not confined to domestic firms. Firms have been trying to connect to foreign partners worldwide. Although offshore outsourcing grants firms various benefits, they present big cultural challenges. However, there is little research on the impact of cultural or country factors on outsourcing. The goal of this paper is to synthesize the outsourcing success literature and develop propositions for outsourcing success in the context of offshore outsourcing. This paper proposes that cultural effects should be included in evaluating the success of offshore outsourcing. Knowledge sharing and the scope of outsourcing are adopted in the base outsourcing success model from previous literature. In the extended model partnership quality is included as a mediator and organizational capability and outsourcing relationship type are also included as moderator. Finally, the integrated framework of offshore outsourcing success includes cultural factors as moderators of the relationships between outsourcing success antecedents and the success of offshore outsourcing. Reasoning for propositions, managerial implications, and future research directions are discussed.

The purpose of this research is to identify causalities among service quality, service value, customer satisfaction and customer loyalty. A Structural Equation Model is used to test the hypothesis of conceptual model. To test the model, we collect data by conducting a survey with 508 patients. Empirical result indicates that three factors such as tangibles, assurance, and empathy have direct impact on service value and customer satisfaction. Especially, customer loyalty is positively related not with service value but with customer satisfaction.
