Purpose:?The purpose of this study is to analyze the causal relationship between top management 's leadership and construction quality management activities that affect construction management performance based on construction quality management. Methods:?As its method, the causal relationship between the leadership of top management and the key management factors of construction quality management activities affecting management performance is analyzed by using the structural equation model. The construction companies used in the analysis sample conducted surveys on companies that are conducting ISO, KOSHA, OHSAS, DQC, and so on. Results:?It was revealed that top management's leadership has a great influence on management performance and all management factors of construction quality management activities. However, safety management does not affect the management performance of construction quality management activities. And top management's leadership on management performance are explained by the mediating effect of cost, time, quality and communication among management factors of construction quality management activities. Conclusion:?In the previous study, the quality management activities and the ISO - based integrated total quality management system (TQM) applied in the manufacturing or service industries were presented as empirical results. However, this study presents the results of different studies by presenting empirical study results by selecting time, cost, quality, safety and communication as key management factors of quality management activities of construction companies through reviewing and analyzing previous studies in construction field.

Work delay is the one of facts that make the reliability of construction business decrease. Building a causal classification system of work delay and deducing the managemental item for it gives a great competition to the construction industry. It is, however, so rare to study about work delay so far. Therefore, this research analyzed a questionnaire, which is focussing on the public apartment construction, to look into the causal root factors and deduce the work delay factors. Finally, we suggest a major managing point to remove effectively the work delay factors.

Purpose: This study was to identify the factors influencing turnover intention of nurses in small and medium-sized hospitals. Method: The participants in this descriptive survey on causal relations were 192 nurses who were working at small and medium-sized hospitals in Daegu city. The data were collected by self-reporting questionnaires and analysed by the SPSS Win 14.0 program using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and stepwise multiple regression. Result: The mean for job characteristics scores were 2.90, the job satisfaction scores were 3.00, the organizational commitment scores were 3.00, job stress scores were 2.42, the turnover intentions scores were 3.08. Turnover intention according to general features were shown as following; age, marital status, clinical career, work schedule type, frequency of night duty. The relationship between turnover intention and job stress had positive correlation. But the relationship between turnover and other factors that job satisfaction, organizational commitment had negative correlation. The causal factors of turnover intention were organizational commitment, job satisfaction, job stress, and job characteristics, frequency of night duty. $R^=.39$. The organizational commitment were the highest significant predictors of turnover intention. Conclusions: The findings of study suggest that broad intention program should be provided to prevent problems of turnover.

Purpose: The present study was designed to examine the casual relationships among performance and arts information service quality, initial trust, user satisfaction, reuse intention and prosumer activity in social network service(SNS). Also, we intended to explore significant factors on use performance of SNS through causal model analysis in the viewpoint of total effect. Methods: As a survey tool, questionnaire has obtained validity and reliability through literature survey, exploratory survey and pretest and sample 403 was selected. For statistical treatment of pretest and main analysis, SPSS18.0 and AMOS18.0 were employed and structural equation model was employed as analysis method. Results: Result of this study shows as follows. Two factors (precision and reciprocal action) have an effect on user satisfaction, initial trust, reuse intention and prosumer activity. We found that with an importance of initial trust, prosumer activity can be a useful and significant factor in causal relationship of SNS. Conclusion: The present study shows that two factors(precision and reciprocal action) in via of initial trust, were important factors that related companies have to emphasize to raise performance, And also we confirmed new factor 'prosumer activity' through this study. However, the present study has some limitations to be studied in the future.

With the mounting concerns over environmental issues, green construction is gaining a place in the global construction industry. However, rare research has been conducted to analyze green construction projects, especially in the aspect of project schedule performance. As a result, this study aims to investigate the degree of project delay in green building construction, analyze the factors affecting schedule delay of green building projects, and finally provide recommendations to improve schedule performance of green building project. To achieve the objectives, a comprehensive literature review was carried out, followed by a survey conducted with 30 companies that provided data from 220 traditional and 96 green building projects. The analysis of the responses identified that 15.9% of the traditional building projects were delayed while 32.3% of the green building projects were completed behind schedule. Furthermore, the amount of the delays in green building projects was an average of 4.8% of their planned schedule. The top 5 critical factors that can cause delay in green building projects were identified as: (1) speed of decision-making by clients; (2) speed of decision-making involving all project teams; (3) communication/coordination between key parties; (4) level of experience of consultants; and (5) difficulties in contractors' project financing. Lastly, a list of recommendations was introduced, aiming to reduce schedule delay in green building construction projects based on the observations. This study will serve as s a base for further research on the enhancement of green building project schedule performance.

This study tried to build a structure model for the Korean flatfish aquaculture market by a system dynamics approach. A pool of several factors to influence the market structure was built. In addition, several reasonable factors related to the flatfish aquaculture market were selected to construct the causal loop diagram (CLD). Then the related stock/flow diagrams of the causal loop diagrams were constructed. This study had been forecasting a production price and supply, demand, and consumption volume for the flatfish market by a monthly basis, and then made some validation to the forecasting. Finally, four governmental policies such as import, storage, reduction of input, and demand control were tentatively evaluated by the created model. As a result, the facts that the demand control policy is most effective, and import and storage policies are moderately effective were found.

The Location Based Services (LBS) comprise spatial information and mobile technology allow users to receive various services based on Global Positioning Systems (GPS). Although, spatial information based services are very useful, it has lots of possibility to damage privacy protection. But the contents of the legislation by government have problems conflicted between protection of a person's location information and invigoration LBS. Therefore, in this study suggest a causal model to deal with user satisfaction and factors affecting spatial information based services to customer perspective. The proposed research model is tested empirically with one hundred and forty one usable questionnaires and partial least square (PLS) method. Experimental results showed that the usefulness, playfulness, and service quality play a prominent role in influencing the spatial information services satisfaction compared to other factors. But, easy of use and perceived risk are not significant.

Subjects of this study were 621 children selected from 5th and 6th grades of elementary schools in Pusan. Factors associated with parents and peers varied by type of peer maladjustment(aggressive type and withdrawn type, compared with a control group). Particularly, the level of factors associated with peers varied from the control group by peer maladjusted types(aggressive types and, withdrawn types). Causal relationships of parents' rejection, victimization, negative representation by parents and by peers on child？s maladjustment varied by behavior types. Negative representation of peers had a direct effect only on withdrawal. On the other hand, negative representation of peers had no effect on aggression. Victimization had a first total effect on both withdrawal and aggression.

This paper aims to study regional difference in strawberry farming technology and its causal factors based on the survey of controlled strawberry farmers in three major strawberry cultivating regions, which are Nonsan county of Chungnam Province, Damyang County of Junnam Province and Guchang County of Kyungnam Province. There are differences in variety adoption, packaging and grading method which cause the farming income gap among these regions. Farmers of Guchang County, who adopt new variety Yeobong and packing system, raised highest gross receipts but ranked next to Damyang in terms of net income because of high packing cost. Farmers of Nonsan County earned lowest income because of poor quality and low price in spite of adopting packing cost saving method. Therefore, results of this study shows that successful farming technology depend on whether or not farmers adopt market oriented technology. It is suggested that direction of strawberry farming technology should focus on adopting new varieties which can contribute to increasing farmers' paid price and developing technology of reducing cost such as labor saving and packing machine.
