There is a growing awareness about the role of the board of directors in decision making, which is crucial to vitalize board activities in Korean firms. Given the academic and social needs, the current study is designed to identify the relationship between board independence and the board involvement of directors, highlighting the important aspects of information provision from diverse channels and information sharing among external directors. In this study, I include not only traditional variables to address the structural independence of the board but also the information provision and information sharing variables to explain how external directors, on average, are involved in board decisions. The research results from 136 Korean business samples show positive relationships between board independence and board involvement, but the influence of information provision and sharing proves to be significant in increasing the level of the board involvement of external directors. These findings suggest that active communication and information sharing among external directors, as well as an independent structural design for the board of directors, are important factors to improve the level of board involvement. Based on these results, the current paper provides theoretical and practical implications for corporate governance and knowledge management. Future research directions and limitations are also discussed.

Smart City is gaining attention with the advancement of Information and Communication Technology (ICT). ICT provides the basis for smart city foundation; enables us to interconnect all the actors of a smart city by supporting the provision of seamless ubiquitous services and Internet of Things. On the other hand, Crowdsourcing has the ability to enable citizens to participate in social and economic development of the city and share their contribution and knowledge while increasing their socio-economic welfare. This paper proposed a hybrid model which is a compound of human computation, machine computation and citizen crowds. This proposed hybrid model uses knowledge-based crowdsourcing that captures collaborative and collective intelligence from the citizen crowds to form democratic knowledge space, which provision solutions in areas of civic innovations. This paper also proposed knowledge-based crowdsourcing framework which manages knowledge activities in the form of human computation tasks and eliminates the complexity of human computation task creation, execution, refinement, quality control and manage knowledge space. The knowledge activities in the form of human computation tasks provide support to existing crowdsourcing system to align their task execution order optimally.

PURPOSE: The purpose of this study is to assess the difference in the effect of provision of feedback on knowledge of performance and knowledge of result in the training using somesthetic video game aimed at enhancement of balance of hemiparalysis patients due to stroke. METHODS: 20 stroke patients participated in the study. The participants were randomly divided into 2 groups, namely, the knowledge of performance feedback group (KP group, n=10) and the knowledge of result feedback group (KR group, n=10). Both groups received somesthetic video game training 5 times (30 minutes each) a week for total of 4 weeks. The KP group received feedback on the patterns of movement in execution of somesthetic video game. The KR group received feedback on the scores acquired following execution of somesthetic video game. Verification of the significance of the data was performed through paired t-test and independent t-test. RESULTS: Both groups displayed significant reduction in the movement of center of pressure (COP) and Timed up and Go (TUG), and significant increase in the Berg Balance Scale (BBS) following the training. Although the movement of COP was reduced for the KP group in comparison to the KR group, it was not statistically significant, and there was significant reduction in TUG and significant increase in BBS. CONCLUSION: The above results illustrate that provision of feedback on knowledge of performance is more effective than feedback on knowledge of result in somesthetic video game training for the purpose of enhancement of balance in stroke patients. Therefore, provision of feedback on knowledge of performance is necessary in somesthetic video game training for stroke patients.

In the future society, a means to verify the identity of the information owner is required at the beginning of most services that the information owner encounters, and the emergence and gradual spread of digital identification that proves the identity of the information owner is essential. In addition, as the utilization value of personal information increases, discussions on how to provide personal information are active. Therefore, there is a need for a personal information management method necessary for building a hyper-connected society that is safe from various hacking, forgery, alteration, and theft by allowing the owner to directly manage and provide personal information management. In this study, a decentralized identity information management model that overcomes the problems and limitations of the centralized identity management method of personal information and manages and selectively provides personal information by the information owner himself and implemented a smart personal information provision system(SPIPS: Smart Personal Information Provision System) using a smartphone.

Risk information may be one of the most important factor for worker's safe behavior because that safe behavior can be oriented by attitude based on risk information. Traditionally KAP(knowledge, attitude and practice) model was useful frame for the change of human behavior. Knowledge is formed by information through experience and education. Worker's health may be prevented by his or her own active safe behavior based on risk information. This paper is to investigate the effect of labor union on the provirion of risk information by labor union. Data for analysis is the third Korean Working Conditions Survey done by Occupational Safety and Health Research Institute in 2011. The sample size is 50,032 economic active person surveyed by household interview survey with structure questionnaire by trained interviewer. The difference of risk information provision among employees was tested by mean difference test. The level of risk information of employees of companies with labor union is higher than that with non labour union. This paper has some implication for the promotion of safe behavior of employees through risk information provision mediated by labor union. Some limitation of this study may be considered because of using the cross sectional survey data.

Listening has been a neglected research area despite the crucial role it plays. The present investigation was aimed at examining how the provision of topical knowledge and learners' listening proficiency level affect learners' listening performance under four different preparatory activity conditions: topical knowledge, vocabulary list, language structure, and no activity. A total of 134 participants, assigned to the four different activity groups, took part in the study. The results revealed that the learners who were provided with topical knowledge before listening performed significantly better than the other learners, followed by the vocabulary list group and language structure group, which might be attributed to the activation of their content schemata. The learners who did not perform any preparatory activities achieved the lowest scores. When it comes to the impact of listening proficiency, it was revealed that learners' proficiency level had a significant influence on learners' listening performance, and there was a significant interaction between the learners' level of listening proficiency and preparatory activity. Providing relevant knowledge was effective for both higher level and lower level learners, whereas teaching vocabulary before listening was effective for higher level learners but was not for lower level ones. Based on the results, some pedagogical implications and suggestions for future research were discussed.
