In order to cultivate the talents needed in the 4th industrial revolution era, it is necessary to select gifted students and train them systematically. The affective characteristics of the gifted are self-concept, personality, sociality, motivation, morality, attitude and interest, and these are important factors that affect science achievement. In particular, computer scientific attitude is an important variable affecting computer science achievement. This study developed a computer scientific attitude test based on TOSRA developed by Fraser to measure the affective characteristics of information-gifted students. The computer scientific attitude test is composed of 7 areas: social implications of computer science, attitude to computer scientific inquiry, adoption of computer scientific attitudes, adoption of computer scientific attitudes, leisure interest in computer science, career interest in computer science, and normality of computer scientists. The relationship between computer scientific attitude and academic achievement of gifted students was analyzed using the developed test. To determine find out whether computer scientific attitude significantly predicts academic achievement, the results of a regression analysis showed that t = 2.543 and p = 0.025, indicating that the average of computer science attitude significantly predicted academic achievement.

Building information modeling (BIM) has been receiving attention as an integrated information model instead of CAD since the 2000s. BIM technology was first used in the architectural field and was later introduced to the civil engineering field. However, the government announced a plan for the application of BIM to 20% of all SOC projects from 2020, so the adoption of BIM technology is expected to accelerate. In order to successfully adopt BIM, a systematic structure should be supported for integrated design information and implementation technology. Also, it is important to establish the relationship between information systems because many complicated factors are intertwined in the construction industry. In this study, we propose a framework for constructing integrated information through identifying the information relations for introducing BIM in the civil engineering industry. We applied this framework to a bridge project to confirm its effectiveness. This study can be applied to the integrated management of the construction process and costs by introduction of a work breakdown structure (WBS) to BIM. In addition, this study is expected to contribute to the adoption of BIM in the civil engineering field through the proposal of information system standardization in this field.

This study investigates the effects of individual and group level factors on the use of GSS (Group Support System) and task performance from GSS use. GSS facilitates the group work, so that GSS adoption is not necessarily influenced only by individual perceptions on information systems. Adaptive Structuration Theory (AST) in our study to explain the adoption and success from GSS use. AST contends that the success of IS is not necessarily the technical fit between tasks and technology, instead the political outcome among user socializations. We have the following two research inquires: Are the IS use and performance maximized when information technologies are provided properly?; and, Does TTF always influence positively on IS use (or performance)? To research these issues, we investigate the influence of TTF (Task-Technology Fit) on use and performance of GSS, which is introduced to foster collaboration among organizational members. Drawing insights from the AST, we examine if COA (Consensus on Appropriation) among group members and FOA (Faithfulness of Appropriation) between those who use technology and who design it show any moderating effect. A questionnaire survey was conducted on firms using the GSS for one month from June 2 to June 27 2005 and a sample of 303 responses was used for a statistical analysis. The result demonstrates that TTF exerts a positive influence on use and performance of GSS. We find that the stronger the COA, the greater the effect of W on use of GSS and performance. FOA likewise has a positive effect on both use of GSS and performance. The TTF model has been widely applied to studies on individual performance of information system, whereas the AST theory specifically explains members' adaptation process to information system. By integrating the AST theory with the TTF model, the study contributes to heightening our understanding on if and how individual performance varies with the use of GSS.

For a social venture in early stage, it is very difficult to set up a strategy as it has to pursue two contradictory goals; economic value and social value. The platform strategy can be good alternative solution for social ventures as it seeks building-up connections with other businesses to co-create value despite of limited resources. A Korean social venture, JUMP! which adopted platform strategy in the early stage, and successfully applied 4 key factors of platform strategy; core competency, value creation ability, efficiency and network effect, has been able to develop sustainable growth for itself and induce innovation and growth among the participants within the platform. This study was intended to research effect of adoption and successful application of platform strategy for social ventures in the early stage of start-up and draw conclusion through case study that platform strategy works for sustainable growth of social ventures.

Cloud computing is getting a lot of attention by many people and businesses due to IT environmental changes such as the proliferation of smart devices, the increase of digital data, and the cost of IT resources. More individuals use personal cloud computing services for storing and managing information and data. Therefore, this study proposed determinants that are expected to have an influence on evaluating the value of cloud computing based on the value-based adoption model, examining the relationship between the continuous use intention of cloud computing. Results of the study show that usefulness, convenience of information access, extensibility had a positive impact on perceived value while privacy concerns and costs had a negative impact on perceived value. In addition, perceived value was found to have a significant effect on the intention to continue use of cloud computing. Finally, trust was found to have a significant effect on the perceived value and the intention to continue use of cloud computing. The findings are expected to provide useful information for understanding the factors that individual users consider important in the steadily growing cloud computing market.

In contemporary society, the importance of 'Citizen Participation' has been recognized and actively used in various fields. Archives are also planning citizen participation activities according to the trend, but there is a limit to taking the form of passive participation activities such as participation in contests and donation of records. The ultimate purpose of this study is to prepare issues and specific action plans to induce more active citizen participation in domestic archives. To this end, first, previous studies related to citizen participation in the field of records management were reviewed, and terms and concepts were established. Next, advanced cases that are stably operating overseas were selected and analyzed from various aspects, and through this, specific program operation elements and pros and cons were identified. After that, the current status of domestic archives that have or are planning to engage in citizen participation activities was investigated to derive factors to be considered from a practical point of view when introducing the actual program. Based on this study, it is hoped that it will contribute to the establishment of a participating recording culture by designing and operating Citizen-Participating Programs suitable for individual archives.

This study is to investigate the factors affecting the usage intentions of 5G service between 5G service subscribers and non-subscribers based on the Integratively Extended Technology Acceptance Model in the initial B2C 5G service market. We designed the integratively extended technology acceptance model to find the more specific factors to affect the usage intentions by integrating the exogenous factors including the technical factors, the social factors, and the personal factors with the ETAM(Extended Technology Acceptance Model). Referring to the previous studies, we constructed the hypotheses of structural influence relationship from the exogenous factors to the dependent usage intentions factors through the mediating belief factors. We designed the 5G service usage intentions model based on these hypotheses and operational definitions of the factors. Using the analysis of SEM(Structural Equation Model), the proposed model and the hypotheses were empirically tested by the data collected from 245 subscribed respondents and 245 non-subscribed respondents. As a result, the perceived ease of use has an effect on the perceived usefulness and enjoyment, and the perceived usefulness/enjoyment and the personal innovativeness have positive effects on the usage intentions of both groups.

Many companies have recently become interested in using social networking sites such as Twitter and Facebook as a new channel to communicate with their customers. For example, companies often offer "special deals" (e.g., coupons, discounts, free samples, etc.) to their customers who participate in promotions or events on social networking sites. Companies often make important announcements on their products or services on social networking sites. By doing so, customers are encouraged to continue to have relationships with companies on social networking sites and to recommend the companies' presence on social networking sites to other potential customers. Moreover, customers who keep close relationships with companies on social networking sites often provide the companies with valuable suggestions and feedback. For instance, Starbucks has more than 2 million followers on Twitter, and often receive suggestions and feedback for their product offerings and services from the followers on Twitter. Although companies realize potential benefits of using social networking sites as a channel to communicate with their customers, it appears that many companies have difficulty forging long-lasting relationships with customers on social networking sites. It is often reported that many customers who had followed companies on Twitter later stopped following them for various reasons. Therefore, it is an important issue to understand what motivates customers to continue to keep relationships with companies on social networking sites. Nonetheless, due attention has yet paid to this issue until recently. This study intends to contribute to our understanding on customers' intention to continue to follow companies on Twitter and to spread positive word-of-mouth about companies on Twitter. Specifically, we identify seven potential factors that customers perceive as important in evaluating their experience with companies on Twitter. The seven factors include similarity, receptivity, interactivity, ubiquitous connectivity, enjoyment, usefulness and transparency. We posit that the seven perception factors can affect the two types of satisfaction, emotional and cognitive, which can in turn influence on customers' intention to follow companies on Twitter and to spread positive word-of-mouth about companies on Twitter. Research hypotheses formulated in this study were tested with data collected from a questionnaire survey administered to customers who had been following companies on Twitter. The data was analyzed with the partial least square (PLS) approach to structural equation modeling. The results of data analysis based on 177 usable responses were generally supportive of our predictions for the effects of the seven factors identified and the two types of satisfaction. In particular, out results suggest that emotional satisfaction was strongly influenced by perceived similarity, perceived receptivity, perceived enjoyment, and perceived transparency. Cognitive satisfaction was significantly influenced by perceived similarity, perceived interactivity, perceived enjoyment, and perceived transparency. While cognitive satisfaction was found to have significant and positive effects on both continued following and word-of-mouth intentions, emotional satisfaction had a significant and positive effect only on word-of-mouth intention.

Twenty years have passed since the adoption of natural recreation forests and each forest has its own characteristics. However, there is hardly any classification among the natural recreation forests. The purpose of this study is to classify the forests by considering the supplier's perspective as well as the user's perspective in order to provide fundamental materials for the operation of the natural recreation forests. A factor analysis was conducted to identify the common characteristics of the selected twelve variables by pre-selection and survey of experts. K-means cluster analysis was conducted among those factors to classify the natural recreation forests in Korea. Four factors were drawn after the factor analysis and the factors were named according to the variables and sizes as 'The use performance and visiting condition factor', 'Education and settlement factor', 'Internal activation factor' and 'Potential factor' In addition, the cluster analysis of an $85{\times}4$ matrix was conducted for the points of the drawn factors and the final classification consists of five groups. The results of this study may contribute to providing fundamental materials for the operation and management of natural recreation forests. Also, it may act as a reference when investigating the natural recreation forests of Korea. Proposing the classification natural recreation forests could be helpful in selecting the proper recreation forest in the future. Based on the established model, fundamental materials could be provided to improve the profitability of the natural recreation forests by effectively expanding the number of tourists, creating new natural recreation forests and proper maintenance and management.
