According to the dynamic changes in the business environment, the structural transformation of firms has had an observable trend. An increasingly large number of firms have been transforming into either project-based organizations or project expert groups. This study aims to investigate the antecedents required for the optimal level of empowerment with consideration of the project-based team environmental nature and job characteristic. Three factors are applied to measure the significant effects on psychological empowerment as the result variables. To determine the antecedents and consequent factors of psychological empowerment, employees' interviews and precedent studies are used. For the empirical study, four determinants of empowerment variables are modeled into a second-order reflective construct. This study finds that psychological empowerment significantly affects performance. Therefore, this study can serve as a guideline for development and operating methods for project success.

Smart grid (SG) software platforms and communication networks that run and manage the entire grid are increasingly concerned about cyber security. Characteristics of the smart grid networks, including heterogeneity, time restrictions, bandwidth, scalability, and other factors make it difficult to secure. The age-old strategy of "building bigger walls" is no longer sufficient given the rise in the quantity and size of cyberattacks as well as the sophisticated methods threat actor uses to hide their actions. Cyber security experts utilize technologies and procedures to defend IT systems and data from intruders. The primary objective of every organization's cybersecurity team is to safeguard data and information technology (IT) infrastructure. Consequently, further research is required to create guidelines and methods that are compatible with smart grid security. In this study, we have discussed objectives of of smart grid security, challenges of smart grid security, defensive cybersecurity techniques, offensive cybersecurity techniques and open research challenges of cybersecurity.

The Korea Augmentation Satellite System (KASS), which is under development in Korea as a Satellite Based Augmentation System (SBAS) is expected to broadcast SBAS messages to air space in Korea according to the international standards defined by the International Civil Aviation Organization (ICAO) and the Radio Technical Commission for Aeronautics (RTCA). Around 13 SBAS messages are broadcast in every second to transmit augmentation information which can be applicable to a wide area in common. Each of the messages requires a different update interval and time-out according to the characteristics, purpose, and importance of transmitted information, and users should receive and combine multiple SBAS messages to calculate SBAS augmented information. Thus, a time to take acquiring first SBAS position by users differs depending on broadcasting various SBAS messages with which order and intervals. The present paper analyzes the considerations on message scheduling for broadcasting of KASS augmentation information and proposes a design of KASS message scheduler using the considerations. Compared to existing SBAS systems, which have a wide range of service area, a service area of the KASS is limited to Korea only. Thus, the numbers of ionosphere grid points and satellites to be augmented are expected to be smaller than those of existing SBAS. By reflecting this characteristic to the proposed design, shortening of broadcast interval of KASS message is verified compared to existing SBAS and a measure to increase a speed of acquisition of user navigation solution is proposed utilizing remaining message slots. The simulation result according to the proposed measure showed that the maximum broadcast interval can be reduced by up to 20% compared to that of existing SBAS, and users can acquire KASS position solution faster than existing SBAS.

This study provided implications for applying learner-centered teaching methods in the field of management education by adopting flipped learning and team-based learning to Business Communication classes and operating the classes according to its characteristics. Business communication capability, especially related to drawing up a document or a written report, is considered one of the crucial factors for making individuals valuable in an organization. For the identification of the subject outputs, a total of 64 students from the first and second semesters in 2018 were sampled, and the Wilcoxon signed rank test and paired t-tests were carried out. The results show that all types of communication capabilities have significantly increased at the end of each of the semesters. Also, the overall satisfaction level proved to be higher at the end rather than at the beginning of each semester. This study is especially meaningful because the results suggest concrete ways to apply learner-centered teaching methods for business education.

Pumasi and Cooperative Child Care Sharing have had positive results among participants and show possibilities of spreading out to the community in general. However, performance was not proved where it is clarified, and the experience of 23 local Healthy Family Support Centers have that ran the demonstration project were unable to be collected. It is the point of time when the initial backing up is important but the centers do not have the systematic support. Therefore, this research presents an effective management plan through qualitative research involving Pumasi participants and person in charge. The operation strategies by the stage of the project were as follows: First, in the beginning stage, the person in charge establishes the target and vision of the project. Second, when comprising the Pumasi team, it was necessary to consider their characteristics according to the team organization subjects. Third, it is necessary to extend the turn-off time and provide many programs so that the various populations can participate. Fourth, in the advertising step, word of mouth and individual contact needs to be utilized. Fifth, in a medium or small city or an urban-rural complex area, the person in charge should support the participants' Pumasi activities. Sixth, various programs such as a passive and active parent education program and Pumasi education program for the leader needs to be provided for the activation of Pumasi activities. Lastly, a cooperative child care sharing location needs to be constructed by the duality system of the base space and outer space. In this location, the inside play space for the children is essential.

Faultline theery, introduced by Lau and Murnighan in 1998, adds valuable explanations in addition to what previous demographic studies have explored. However, previous research has not been able to fully integrate the characteristics embedded in the workplace environments, and the influence of faultlines in IT industries has yet to be explored. In this study, IT related influence is given considerable weight into traditional faultline theory and the impact of IT-based faultlines is revealed. Our study indicates that IT-based faultlines have a negative impact on task conflict and process conflict, and these two effectively also effectively mediate the influence of IT-based faultlines to group performance. Two potential moderators are studied and the Tesults indicate that commitment has no moderating effect between IT-based faultlines and group performance while open communication has strong moderating effect. Our empirical study reconfirmed that faultlines are important indicators in group work and also that faultlines are intimately related to various conflicts and group outcomes. We hope our research findings will be beneficial to organizations concerned with effective and efficient group work.

Decision effectiveness depends on type of knowledge within team members generated by decision making process. Thus, organization in accordance with teams' experience and capability ultimately achieve their desired outcome. However, previous research has not addressed a mediating role between different knowledge type in decision making and product competitive advantages(pioneering advantage and product quality superiority). Based on the knowledge-based view, we model how different knowledge characteristics in decision making affect to acquire each of knowledge in decision making effectively and then to apply acquired knowledge in decision making. Anchored in a source-position-performance (SPP) framework (Day and Wensley's, 1988), we shed light on the effects of three knowledge characteristics dimensions in decision making process on knowledge management competences in decision making for a new product project. We also examine the relationship between two dimensions of NPD knowledge management competences, and product competitive advantages which consist of market pioneering advantage and product quality superiority. To test the relationships, the empirical analyses are conducted using a sample of team managers who participated in NPD projects. This study suggest that managers should increase their acquirability and applicability of knowledge by integrating complexity of diverse and new knowledge, developing codifiability of well-documented knowledge, and creating the sharing common knowledge among NPD team members. Thus, they are able to outrun major competitors in terms of pioneering advantage and product quality superiority perspective.
