Agile methodologies in software development, including the development of artificial intelligence software, have been widespread over the past several years. In spite of the popularity of agile methodologies in practice, there is a lack of empirical evidence to identify determinants of success of software projects in which agile methods are used. To understand the role of clients in software project where agile methods are used, we examine the effect of client-side factors, including lack of user involvement, unrealistic client expectations, and constant changes of requirements on project success from practitioners' perspective. Survey methods are used in this study. Data were collected by means of online survey to IT professionals who have experience with software development methodologies, and ordered logit regression is used to analyze the survey data. Results of our study imply the following managerial findings. First, user involvement is critical to project success to take advantage of agile methods. Second, it is interesting that, with an agile method, constant changes of client's requirements is not a negative factor but a positive factor of project success. Third, unrealistic client expectations do negatively affect project success even with agile methods.

This study focuses on (1) the relationship between the network intensity of top managers and the R&D investment of Korean firms, and (2) the moderating effects of the type (related-division vs. unrelated-division) and system (physical division vs. spin-offs) of corporate division on this relationship. The sample of this study was all type and/or system of corporate division implemented by Korean firms during 18-years (1999-2016) study periods. The results of multiple regression analyses as follow. First, as was expected in hypothesis 1 the network intensity of top managers has a strong positive linear relation with the R&D investment of Korean firms. Second, regarding the moderating effect of division type the results show that related-divisions significantly intensify the positive relationship of the network intensity of top managers with the R&D of Korean firms although unrelated-divisions did not. Third, in the analysis of moderating effect of corporate division system the results present the stronger positive moderating effect of spin-offs rather than physical divisions. The findings of the study implies that strong network intensity of top managers can be beneficial to long-term decision such as R&D investment of Korean firms. They accords to network theory that emphasize the importance of strong network effect among top managers based on their trust. The findings also implies that researchers and practitioners should consider organizational-level factors such as organizational structure, culture, corporate governance, etc as well as individual-level factors such as the characteristics and relationships of organizational members when making the decision for firm.

Blockchain is considered as an innovative technology along with Artificial Intelligence, Big Data, and Internet of Things. However, since the inception of the genesis of blockchain technology, the cryptocurrency Bitcoin, the technology is not utilized widely, not let alone disruptive applications. Most of the blockchain research deals with the cryptocurrency, general descriptions of the technology such as trend, outlook of the technology, explanation of component technology, and so on. There are no killer applications like Facebook or Google, of course. Reflecting on the slow adoption by businesses, we wanted know about the current status of the research on blockchain in Korea. The main purpose of this paper is to help business practitioners to identify the application of blockchain to enhance the competitiveness of their organization. To do that, we first use the framework by Iansiti et al (2017) and categorize the blockchain related articles published in Korea according to the framework. This is to provide a benchmark or cases of other organizations' adoption of blockchain technology. Second, based on the value proposition of blockchain applications, we suggest evolutionary paths for adopting them. Third, from the demand pull perspective of technology adoption for innovation, we propose applicable areas where blockchain applications can be introduced. Fourth, we use the value chain model to find out the appropriate domains of blockchain applications in the corporate value chains. And the five competitive forces models is adopted to find ways of lowering the power of forces by incorporating blockchain technology.

The purpose of this study is to apply the Servicescape, which is used to measure the spatial services in marketing, to the studies on university libraries, in order to identify the influence of the library spaces and facilities on the satisfaction and continuance intention of the users of university libraries. For this purpose, questionnaires and in-depth interviews were conducted for users in ten private universities located in Seoul. Servicescape factors of the libraries showed that cleanliness, comfort, aesthetics, and convenience had a significant influence. Of these, convenience turned out to have the highest level of influence upon satisfaction, followed by cleanliness, aesthetics, and comfort. Descriptive statistical analysis showed whether there were significant differences in satisfaction and continuance intention based on the differences in the characteristics of the samples. Findings show that it would be necessary to provide spaces that can accommodate the various functions of a university library; seek advancement of the services; and develop the spaces of a library in consideration of cleanliness, comfort, aesthetic, and convenience. This study introduced the concept of Servicescape for the first time in the field of library and information science. This study implies that the results assist a more detailed analysis for the Library as Place dimension of LibQUAL+, and provide a new guideline for practitioners who design library spaces.

The purpose of this study is to test the mediating effect of coping plan and action plan in the relation between leisure-time physical activity(LTPA) intention and exercise behavior and to extend the literature in theory of planned behavior. We examined the mediating role of implementation plan-namely coping plan and action plan in the effect of intention to physical activity on exercise behavior. To attain the goal of study, we asked collegiate students (n=253; male=118, female=105) report their intention toward LTPA, coping plan, action plan, and self-reported exercise behavior. Collected data was analyzed using statistical program software (i.e., SPSS, AMOS) for SEM and mediation analyses. The results revealed that intention toward LTPA was positively related to implementation plan (coping plan and action plan) and exercise behavior. Collegiate students' intention toward LTPA positively predicted their exercise behavior mediated by implementation plans. Specifically, LTPA intention among collegiate students predicted their exercise behavior via coping plan and action plan. The findings showed that coping plan and action plan partially mediated in the relation between LTPA intention and exercise behavior. In conclusion, students' intention to be getting physical active in leisure-time physical activity explains lifetime physical activity or the level of recent exercise behavior possibly via coping plan (e.g., how to overcome barriers to exercise) and action plan (e.g., when and where I exercise and get physically active). The conceptualization of coping plan and action plan in implementation plans and test of its model better to explain the intention-behavior gap would help exercise instructors or practitioners effectively develop their plans and strategies toward targeted exercise behavior.
