This research is to review various theories on leadership and to apply the transformational leadership that is suitable for military organization to captains of small naval vessels. The research comprehends types and adaptability of the leadership of captains, analyzes problems of them, and suggests the more desirable ways to develop leadership. In order to achieve these objects of the research, positive analyses were conducted through research on various documentations and survey. The first procedure was to survey the status of leadership on mine sweeper prior to the education on transformational leadership. The second procedure is to survey the result of the education on transformational leadership. Also, in order to understand the difference among the controlling groups, random vessels were selected for surveying the effectiveness of the application of transformational leadership on the same period of time.

This study explore how framing affects the consumer's attitude toward the bundle products. On the basis of the framing theory, response compatibility hypothesis and regulatory focus theory, this study examine the impact of framing on the consumer's choice in multi-alternative set and analyzes the manner in which he/she selects or rejects an alternative. The data obtained from experiment shows that : 1. Consumers focus on the positive attributes of in selection task, however, in rejection task he/she will focus on negative attributes. 2. Consumers are not influenced by prevention framing when he/she selects an alternative however, he/she is not influenced by promotion framing when reject an alternative. Understanding the underlying cognitive process of choosing abd rejecting in multiple alernatives can help marketers to create effective framing strategies for the bundle product.

The purpose of this study was to explore a support model for domestic ICT companies to advance into overseas markets suitable for the post-corona era along with the rapidly changing global economic situation. As a result of the analysis, first, by analyzing the internationalization cases of domestic ICT companies through the realization theory, in the COVID-19 situation, domestic ICT companies organically respond to crisis situations through ad hoc responses, use of international networks, use of external organizations, and resource-based practices. Through qualitative analysis, we were able to confirm that we are growing overseas while achieving our goals. In addition, strategies for domestic ICT companies to grow through internationalization were derived. Ultimately, it was interpreted as a part that required advancement of government policy according to the government's overseas expansion support system.

The purpose of this study is to investigate a decision making support system for the effective information management. Decision making theory is reviewed and problems are discussed. A model is suggested through the computing of expected monetary value in decision tree technique. The expected monetary value is computed by 1 inking the probability theory with chance node. The selection of right expected monetary value and expected value of perfect information will make great advance the present system. It is concluded that expected monetary value and expected value of perfect information in decision tree techniques will make great aids to advance information management system.

Recently, a new infectious disease, COVID-19, has been spreading not only in Korea but around the world. As a result, the Korean government raised the level of infectious disease crisis alerts to a serious level on February 23, 2020. The purpose of this study is to apply the situational theory of publics to publics segmentation according to the issuance of a crisis alert and to suggest ways to improve the crisis alert system. To this end, the level of public perception on crisis alerts was checked. The verification confirmed that the situational theory of publics is a suitable theoretical framework for analyzing the communication behaviors of the public toward crisis alerts. As a result of the public segmentation, 42.7% were classified as active publics. Based on this, it was suggested to reorganize the crisis alert system as a system for communicating with the public.

The purpose of this study is to identify the types for open innovation of SMEs considering strategic- culture mixed typology and environmental dynamism. The analysis results of 182 SMEs classified into 4 groups are as follows. First, type PD had a positive effect on innovation performance in both in-bound and out-bound innovation and had improved performance through in-bound innovation in a dynamic technical environment. While DH had no significant effect on both innovations. Second, PH and DD, strategy-culture mismatched types, had a single effect of innovation that affected performance. No moderating effects of environmental dynamism had been shown in types PH, DD, DH. SMEs that aim for open innovation should strive to improve performance by aligning change-oriented strategy with creative and challenging culture.

While the importance of information security policies is heightened, numerous empirical studies have been conducted to investigate the factors that influence employee's willingness to comply organizational security policies. Some of those studies, however, were not consistent and even contradictory each other. Synthesizing research outcomes has been resulted as qualitative literature reviews or quantitative analysis on individual effect sizes, which leads to meta-analyze on whole research model. This study investigated 28 empirical research based on the deterrence theory with sanction certainty, severity and celerity. The analysis with random effect model resulted in well-fitted research model as well as all of significant paths in the model. Future research can include informal deterrent factors and contextual factors as moderator variables.

This paper presents a cal center which is a subsystem of a web-based real time monitoring system of intensive care units. Based on Computer-Telephony Integration (CTI) technology, the call center attempts to efficiently and automatically send messages to patients\` families, doctors, and other staffs in hospital via communication media suitable to the occasion. The problem of determining appropriate media can be very complicated by the urgency of a message, calling time, and communication media available to the target person. We use the Dempster-Shafer theory, one of the uncertainty handling methods, to determine the most suitable communication media that will transmit a message rapidly and safely. In addition, we use agent technology to perform the calling process without requiring the intervention of the user of the call center. this call center enables message transfer through various communication media in an integrated environment, and relieves medical staff from the calling process, which in turn will make a contribution toward enhancing medical service.

This study aims to introduce a basic principle to improve the incident detection algorithm using traffic flow diagrams that can classify traffic states with a high reliability on the basis of the analysis of traffic flow characteristics under the recurrent or incident congestions. It is tried to newly classify the traffic states with the speed-flow and speed-occupancy diagrams. This is because McMaster algorithm has a tendancy on not identifying the traffic states exactly using the flow-occupancy diagram. In this study it shows that the classification of traffic states is applicable to use speed-occupancy relationship Therefore, it is necessary to determine some parameters to correctly classify the areas representing the traffic states and it may be possible to develop a new algorithm to detect the incident with a high reliability.
