The purpose of this study is to examine the effect of peer attachment on life satisfaction of adolescents and to verify the mediating effects of career identity and smart-phone dependency in the process. For this purpose, the data from the sixth year Korean Child and Youth Panel Survey(2015) on 1,823 middle school students were analyzed by hierarchical regression analysis and path analysis among variables. The results of the analysis are as follows. First, peer attachment of adolescents had a significantly positive effect on their life satisfaction. Second, adolescents' career identity had a partial mediating effect on the relationship between peer attachment and life satisfaction. Third, the effect of peer attachment on life satisfaction of adolescents was partly mediated by their smart-phone dependency. On the basis of above findings, the practical programs to enhance career-identity and life satisfaction and reduce smart-phone dependency were presented.

Big data analysis refers the ability to store, manage and analyze collected data from an existing database management tool. Thus, meta-analysis is a statistical integration method that delivers an opportunity to overview the entire result of integrating and analyzing many quantitative research results. Commonly, factors of metabolic syndrome can be defined as abdominal obesity, systolic blood pressure, diastolic blood pressure, triglycerides, and high density lipoprotein cholesterol. In this meta-analysis, we concluded that the path between pre and post of the fasting blood glucose had the largest effect size of (r = -.324). Therefore, the effect of soybean food intervention showed an explanatory power of 10%. The second biggest effect size (r = .256) was found the path between pre and post in the waist circumference. Unfortunately, soybean food intake showed no improvement on abdominal obesity. Thus, we present the theoretical and practical implications of these results.

The development of the information retrieval field is evolving to the research field searching accurately for the information from thing finding rapidly a large amount of information. Personalization and the semantic web technology is a key technology. The automatic indexing technology about the web document and throughput go beyond the research stage and show up as the practical service. However, there is a lack of research on the document information retrieval field about the attached document type of except the web document. In this paper, we illustrate about the method in which it analyzed the text content of the unstructured documents prepared in the text, word, hwp form and it how to construction OWL ontology. To build TBox of the document ontology and the resources which can be obtained from the document is selected, and we implement with the system in order to utilize as the instant of the constructed document ontology. It is effectually usable in the information retrieval and document management system using the semantic technology of the correspondence document as the ontology automatic construction of this kind of the unstructured documents.

In a world where opportunities and chances are common, the phenomenon referred to as "generation maybe" describes people in their 20s and early 30s who are usually being indecisive. With the increase in breadth of information and choices, the number of people who are hesitant in deciding whether to purchase increases at a fast pace, as does the number of products and services targeting this group. In order to enhance our understanding of the phenomenon of consumer hesitation, this study explores contextual factors and consumer characteristics that affect consumer hesitation in the purchase decision-making process. Specifically, this study examines whether seven contextual factors, self-determination tendencies, and five decision-making styles influence consumer hesitation in the product decision making process. An online survey was administered to test our research questions. A total of 309 Korean consumers (female=48.9%) aged from 20 to 35 were surveyed. A regression analysis revealed that four contextual factors (product involvement, need for information on alternatives, relative price, and uncertain need), two sub-dimensions of self-determination (perceived competence and relatedness), and two decision-making styles (price seeking and advice seeking) have noticeable influences on consumer hesitation. We also found that the degree of consumer hesitation positively influences consumer post-purchase satisfaction. The study concludes with discussions and practical implications.

Although we have faced substantial public interests on the issues of small-business, the lack of effective solutions corresponding to them should be worried. This paper introduces findings from the application of Triple Helix to counseling activities for small-business stores with diagnosing problems and suggesting alternatives. The findings of this paper are based on counseling projects conducted by Gyunggi Small-medium Business Corporation, universities in the region, and multiple small-business stores together from June to November in 2015. The application of Triple Helix was positive for increasing the effectiveness of counseling, and this key finding was obtained from action research cycles. It was also confirmed that cooperation from three different entities including company, university and government institute was beneficial in increasing problem identification capabilities by students and providing opportunities for testing knowledge and skills, which means Triple Helix application to small-business helps management education to be more practical. Contributions of this study supplies substantial insights to academic audience, and practitioners can learn positive effects of Triple Helix and potential issues for implementation in the context of small-business counseling.

OBJECTIVES : This study develops an evaluation method, which is useful to inspect pavement condition of specific boroughs. This is because pavement condition is broadly divided into five grades via visual inspection, which does not consider the types of deteriorations, and is decided by an investigator having a subjective viewpoint. This visual inspection method is not a satisfactory method for accurate maintenance when various deteriorations occur. METHODS : The performance model considers several factors such as crack, rutting, and IRI. This method is also modified from borough SPI based on SPI (Seoul Pavement Index). Considering limited budget of borough, PI (prediction index) is suggested, which is related to the grade of pavement condition evaluation and type of materials. Practical correlation review is also conducted with statistical verification by using the Monte Carlo simulation. RESULTS : The results of the study show that modified criteria are reasonable. First, the comparison between the visual inspection result and the SPI result indicates that the R-square value is sufficiently high. Second, through the common section, each evaluation method could be compared, and the result shows considerable similarity, which increases when the range is modified. Finally, PI for predicting remaining life and the random number SPI have common parts, which means that each indicator would be adequate to be used as an evaluation method. CONCLUSIONS : Comparison and analysis results show that the developed evaluation method is reasonable for specific boroughs where financial support is inadequate for the evaluation process by using the newer equipment. Moreover, for more accurate evaluation method, previous visual inspection data should be utilized, and the database of inspection equipment have to be collected.

The theoretical aspects behind the reactor depletion capability of the Monte Carlo code MCS developed at the Ulsan National Institute of Science and Technology (UNIST) and practical results of this depletion feature for a Material-Testing Reactor (MTR) with plate-type fuel are described in this paper. A verification of MCS results is first performed against MCNP6 to confirm the suitability of MCS for the criticality and depletion analysis of the MTR. Then, the dependence of the effective neutron multiplication factor to the number of axial and radial depletion cells adopted in the fuel plates is performed with MCS in order to determine the minimum spatial segmentation of the fuel plates. Monte Carlo depletion results with 37,800 depletion cells are provided by MCS within acceptable calculation time and memory usage. The results show that at least 7 axial meshes per fuel plate are required to reach the same precision as the reference calculation whereas no significant differences are observed when modeling 1 or 10 radial meshes per fuel plate. This study demonstrates that MCS can address the need for Monte Carlo codes capable of providing reference solutions to complex reactor depletion problems with refined meshes for fuel management and research reactor applications.

The purposes of this study are to analyze the degree of satisfaction on forest experience among children, based on a survey of teachers and parents who lead them, and to make proposals based upon the findings. The survey was performed in forest experience for children at Apsan Park in Daegu. The results are as follows. First, there were 78 respondents comprising 34 teachers, 39 parents, and 5 others. The teachers' age groups were distributed evenly between the 20s and 40s and parents' 51.3% were in their 30s and 46.2% in their 40s. Second, all participants responded that forest experience is necessary for children. 80.8% of respondents required continually additional construction. Specifically, parents insisted that forest experience for children should be built up more than the teachers did. Third, as a result of the management and program satisfaction of forest experience for children, 38.5% of respondents wanted increased access and another 38.5% desired unlimited access. In addition, the older teachers preferred more flexible access. Fourth, the safe facility topped the list of the four facilities ranked by importance with 0.39 points, followed by the learning experience field, the shelter facility, and the discretional facility. This study aims to build up basic data in order to make and practically manage forest experiences for children. Therefore, through continuous research, forest experience for children should be established as a practical experience spaces for children.

Recently, collaborations through MCS use in team projects are frequently conducted. This study developed a research model to examine the impact of collaboration through MCS on project performance. Team commitment and team trust regarded as the key drivers of enhancing project performance. Moreover, we also investigated the effect of usefulness of MCS on project performance. We posit ubiquity, polychronic use, and ease of use as the key antecedents of usefulness of MCS. The proposed theoretical framework was tested by using survey data collected from 116 university students who have rich experience with collaboration through MCS. PLS was employed for the analysis of the data. The analysis results showed that team trust significantly influences team commitment and project performance, respectively. However, usefulness of MCS is not significantly related to team commitment, while it play a prominent role in enhancing project performance. The results reveals that ease of use has a significant effect on usefulness of MCS, whereas ubiquity and polychronic use are not significantly related to it. From theoretical and practical perspective, this paper can provide in-depth knowledge of the effects of collaboration via MCS on project performance.
