  • The Korea Atomic Energy Research Institute has developed a performance assessment model implementing the A-KRS concept, which was constructed with the GoldSim. In the A-KRS concept, spent nuclear fuel produced from pressurized-water-reactor operations would be pyroprocessed to reduce waste volume and radioactivity. The wastes to be disposed of in a geologic repository are comprised of metal and ceramic waste forms. In this study, results of simulations conducted to establish credibility and build confidence for the A-KRS model are presented. Specifically, release rates and breakthrough times simulated using the A-KRS model were compared to corresponding results from the U.S. NRC SOAR model. In addition, the A-KRS model results were compared to published release rates from the SKB repository performance assessment. This comparison of the A-KRS model results to other independent performance assessments is expected to form part of a suite of model verification and validation activities to provide confidence that the A-KRS model has been implemented appropriately.

  • The present study identified the determinants of the behavioral intention to purchase an air purifier. This work further examined the moderating effect of interactivity readiness on the relation between the purchase intention and the word-of-mouth (WOM) intention. Our conceptual model included a second-order construct of SNS WOM richness, consisting of three first-order constucts of SNS WOM relevancy, timeliness and sufficiency. Furthermore, SNS WOM usefulness and credibility were incorporated into the model to predict the purchase intention. A total of 312 respondents participated in the survey study. A series of scale refinement processes were performed and a structural equation model analysis was conducted to verify our research hypotheses. The results indicated that SNS WOM richness was found to be significantly predictive of both SNS WOM usefulness and credibility, which in turn, had significant impacts on purchase intention. In addition, results revealed that purchase intention had a significant and positive influence on WOM intention. However, results failed to verify the moderating effect of interactivity readiness on the influence of behavioral intention on WOM intention.

  • With the development of mobile technology, asset management on the Internet have also developed a lot. Drawing on Technology Acceptance Model, this study examines YUEBAO deployment to model consumers' purchase intention to use financial products offered online. In this study, we hypothesized that the characteristics of online asset management product will affect the purchase intention through perceived usefulness and conduct empirical analysis on Chinese consumers. In the study model, the independent variables were considered to include individual involvement, experience, product protection, corporate credibility, convenience, mobility, and familiarity. In addition, the parameters constitute the usefulness, and the dependent variable is the purchase. The results are as follows. First, YUEBAO's complementarity, corporate credibility, convenience, and familiarity have a significant influence on YUEBAO's usefulness. Second, The YUEBAO's usefulness has a noticeable effect on the purchase intention. To perceive the high usefulness, the practicality strategy of enhancing the protection property, corporate reliability, convenience and familiarity of the online asset management product is needed. The study of consumer purchase behavior and consumer purchase intention of online wealth management products is very valuable for academic and practical work.

  • The purpose of this study is to analyze the effect of characteristics of advertising model on brand personality and the effect of brand personality on brand attitude; and analyze whether the characteristics of the advertising model have a direct effect on the brand attitude or indirectly through the brand personality. A survey was conducted from August 10, 2017 until August 31, 2017, and 400 respondents' survey results were analyzed. For data analysis, SPSS 23.0 was utilized to perform descriptive statistics, factor analysis, t-test, and regression analysis. As a result, five brand personality factors were derived, which are aesthetics, safety/expertise, sophistication, pro-environment, youth, respectively. For advertising model characteristics, seven factors were derived, which are credibility, visibility, attractiveness, expertise, similarity, likeability, and familiarity, respectively. This study investigated the relationship between characteristics of cosmetics advertising model, brand personality, and brand attitude. Brand personality does not play a mediating role between advertising model's characteristics and brand attitude. Advertising model's characteristics have a direct effect on the brand attitude. Consequently, Cosmetics companies should recognize the importance of the characteristics of advertising model and implement the marketing strategy by carefully selecting the advertising model so that consumers can relate the characteristics of advertisement model to the brand attitude which will ultimately lead to positive evaluation of the brand.

  • As most systems get more complicated, system analysis using simulation has been taken notice of. One of the core parts of simulation analysis is validation of a simulation model, and we can identify how well the simulation model represents the real system with this validation process. The difference between input data of two systems has an effect on the comparison between a simulation model and a real system at validation stage, and the result with such difference is not enough to ensure high credibility of the model. Accordingly, in this paper, we construct a model based on Trace-driven simulation which uses identical input data with the real system. On the other hand, to validate a model by each class, not by an unique statistic, we validate the model using a metric transformed from F-measure which estimates performance of a classifier in data mining field. Finally, this procedure enables precise validation process of a model, and it helps modification by offering feedback at the validation phase.

  • Creative performance has been regarded as the key to the success of an organization in recent years, and is considered essential for the survival of an organization. Organizations must find and develop creative solutions to deal with a variety of business issues. How can organizations become more creative? To develop creativity, organizations must make it easier to connect the knowledge and perspectives of its various members, who may be scattered around the world, by developing a virtual team. Drawing from the transactive memory systems (TMS), which include expertise location, credibility, and coordination, this study investigates how the positive affect of team members influences the development of creative performance during virtual collaboration where face-to-face team activities are limited. The proposed structured model was empirically tested with cross-sectional data from 322 individuals. Results indicated that the positive affect of team members was found to moderate the relationship between TMS and creativity. Through this study, we expect to provide an understanding of the mechanisms involved in developing creativity among team members in a virtual work environment.

  • Today the role of information systems directly affects the goals and operations of companies and is being strategic. Most of Information System Departments (ISD), however, have been losing the credibility due to their failure to respond effectively to their counterparts in the rapidly changing environment. The purpose of this research is to propose a theoretical framework which systematically studies the innovation of ISD. It is intended to understand the critical factors which have an effect on each level of ISD innovation process. It is also intended to understand the performance of ISD innovation through the innovation process. Besides, we try to clarify the conceptual difference between IS innovation, Information Technology innovation, and ISD Innovation. As a result, we propose the structural model for ISD innovation research by analyzing the innovation theory and previous IS innovation studies.

  • Recently, the development of sustainable building assessment tools as means to invigorate the dissemination of sustainable buildings has been actively progressed. However, many assessment tools involve various problems in terms of assessment method and system framework, which greatly impede their credibility and applicability. If these problems persist over time, the role of sustainable building assessment tools as decision making measures during the design stage will be greatly limited. The objective of the study is to suggest a systematic model for sus- tainable building assessment tools by establishing a logical system of performance assessment framework. For this purpose, the Environmen- tal Impact Assessment(EIA) framework used in selected and modified to fit the building performance assessment. The analysis of performance assessment tools for sustainable buildings was conducted using the EIA framework. Based on the results of the analysis, a framework for the performance assessment of sustainable buildings was established.
