Migration tests were performed with conservative tracers in a fractured zone that had a single fracture of about 2.5 m distance at the KURT. To interpret the migration of the tracers in the fractured rock, a solute transport model was developed. A two dimensional variable aperture channel model was adopted to describe the fractured path and hydrology, and a particle tracking method was used for solute transport. The simulation tried not only to develop a migration model of solutes for open flow environments but also to produce ideas for a better understanding of solute behaviours in indefinable fracture zones by comparing them to experimental results. The results of our simulations and experiments are described as elution and breakthrough curves, and are quantified by momentum analysis. The main retardation mechanism of nonsorbing tracers, including matrixdiffusion, was investigated.

The main purpose of this study was to analysis of the structural relationship between early adolescents' social relationships, self esteem, life satisfaction, and school adjustment. Data harvested from the Korean Youth Panel Survey 2010 was analyzed by means of Structural Equation Modeling (SEM). The results indicate that the model is appropriate in terms of goodness of fit and significant path based on the validation procedure. According to the model, the social relationships have some degree of influence upon self esteem which then goes on to have a subsequent effect on life satisfaction; which in turn have a further influence on school adjustment. Social relationships also have a direct influence on life satisfaction, school adjustment, and self esteem has a direct influence on school adjustment. The paper concludes with an outline of the implications of the present study for future studies on this subject.

The purpose of this study was to investigate whether attachment to primary caregivers and family interaction affect rural children's social competence through self-regulation ability. To achieve this, a survey was conducted with 345 students aged 11-13 attending elementary schools in a rural area of Gyeongsang Province. Data were analyzed using descriptive statistics, Pearson correlation analysis, and path analysis using the AMOS 23.0 program. The main result was that rural children's self-regulation had an indirect effect on attachment with primary caregivers and family interaction through social competence. The findings of this study will contribute to designing a variety of programs that can promote the positive development of social competence among rural children.

The purpose of this study is to examine the data coverage and citation threshold for analyzing SPLC(Search Path Link Count) as a main path of a historiograph of a certain topic in order to provide 'core' papers of global research trends to a researcher affiliated with a local R&D institution. 5 datasets were constructed by retrieving and collecting 2,318 articles on RGB LED on Web of Science published from 1990-2013 and 20,109 articles which cited these original 2,318. The SPLC analysis was performed on each dataset by increasing the threshold of citation counts, and the changes and resilience of the 28 extraced networks were compared. The results of user feedback on 198 unique core papers from 28 SPLC networks received from LED researchers affiliated with a Korean government-sponsored research institution were also analyzed. As a result, it is found that the nodes in each SPLC network in each dataset were differentiated by the citation counts, while the changes in the structure of SPLC networks were slight after the networks' citation counts were set at 40. Additionally, the user feedback showed that personalized research interest generally matched to the global research trends identified by the SPLC analysis.

As PB market segments into premium market, PBs were drawing attentions in terms of creating profits as well as a means to differentiate building up store identity. The purpose of this study makes a comparative study on the difference of consumer attitude formation process in discount store and home-shopping distribution channel which are recently on the upswing. This paper investigated the consumer's attitude formation on the private apparel brand. Subjects of this study were consumers in their $20s{\sim}40s$ who are main customer groups of PBs. The data were analyzed by Structural Equation Modeling and Multi-Group Analysis of Amos 5.0 to verify the difference of the path between store PB and premium PB. Following are the results of the study. Consumer attitude formation path on PB grades showed statistically noticeable difference. In discount store PB, store evaluation didn't directly influence on consumer attitude formation but showed indirect effect. On the other hand, in home shopping premium PB case, product evaluation directly influenced on consumer attitudes with store evaluation. Hedonic attitude dimension connected with behavioral attitude(purchase intention) revealed difference in path. Also consumer's evaluation on variables in model turned out to be different according to brand grade.

The paper presents the economic analysis of optimized-rehabilitation area method considered as one of the preventive maintenance methods in asphalt concrete pavement. The optimized-rehabilitation area was selected based on the analysis of traffic lane characteristics. The main concept of the selected method was to minimize the maintenance cost. The effective width of traffic lane in this method was 70 cm of each wheel path. According to the traffic survey conducted in this research, more than 95% of vehicles passed within the width of each wheel path. The new preventive optimized-rehabilitation area method showed less maintenance cost than the conventional overlay. In addition, traffic congestions and the user cost can be reduced. The research results revealed that the total maintenance cost was reduced by 35% by using the new method compare to the conventional one.

This study is to investigate the impact of hotel service quality and voluntary behavior upon behavior intentions by the actual analysis of four deluxe hotels in Seoul and Incheon. As a research methodology, a statistical package of SPSS 15.0 for window & Path Analysis 7.0 were used with 124 respondents. The empathy of service quality affects the voluntary behavior of the customers composed of three factors. Cooperation out of the voluntary behavior has an effect on the behavioral intentions and the rest of voluntary behavior only influences revisit. Accordingly it suggests that hotel employees should serve the customers with individual care and concern. In addition, it reveals significantly that the empathy is the main factor resulting in voluntary behavior and behavior intentions of the hotel customers.
