This study aims to understand health care consumer's information searching behavior according to their presence of chronic diseases. For this purpose, 240 patients' data of university hospital located in Seoul were collected by surveys from 9 February to 11 February 2016. For statistical analysis, we used SPSS Ver. 26.0. The main results of this study are as follows: First, Chi-square test showed that chronic patients used expert information sources and experiential information sources more than those without chronic diseases. Second, chronic patients were found to search nutrition management, exercise management, and patient case. Lastly, in the case of hospital-related searches, patients with chronic diseases searched more waiting time and medical expenses than those without chronic diseases. The significance of this study is to provide basic data for efficient information provision and establishment of marketing strategies reflecting information needs of health care consumers.

Ant Colony System is new meta heuristic for hard combinatorial optimization problem. The original ant colony system accomplishes a pheromone updating about only the global optimal path using global updating rule. But, If the global optimal path is not searched until the end condition is satisfied, only pheromone evaporation happens to no matter how a lot of iteration accomplishment. In this paper, the length of the global optimal path does not improved within the limited iterations, we evaluates this state that fall into the local optimum and selects the next node using changed parameters in the state transition rule. This method has effectiveness of the search for a path through diversifications is enhanced by decreasing the value of parameter of the state transition rules for the select of next node, and escape from the local optima is possible. Finally, the performance of Best and Average_Best of proposed algorithm outperforms original ACS.

With the emergence of smart media and devices which are able to continuous data monitor, the usage patterns of access and acquire health information are changed. Health contents should be provided to promote intrinsic motivation considering the way of cognizing and processing data in human information interaction. For this, planning for prevention centered health contents is required to utilize personal information and medical big data for engagement with the contents. Therefore, this paper reviews previous studies of health communication dealing with users' information literacy like e-health literacy. In addition, the paper classifies ways of communication when mediate IT as immediacy, interaction and data capturing. In conclusion, strategies of health contents for promoting users' intrinsic motivation are explored and its implications are discussed.

본 논문은 국내 소프트웨어 산업에 있어서 기업의 시장 활동과 관련된 특성을 분석하고 정부의 정책 및 역할을 분석하였다. Porter의 국가 경쟁력 모형을 기본 프레임워크로 하여 국내의 소프트웨어 산업에 있어서의 수요조건의 특성과 이에 관련된 관련 정책 방향을 점검하였다. 실증적 자료가 부족한 국내의 소프트웨어 산업을 대상으로 탐색적 성격의 시장 활동 분석용 설문을 작성하여 약 200개의 소프트웨어 사업자를 대상으로 설문을 수행하여 이들 사업자들이 느끼는 시장 활동의 특성을 분석하였으며, 이를 바탕으로 정부의 역할에 대한 정책적 시사점을 도출하고자 하였다.

The objective of this study is to verify the effects of shopping tendencies and information search on the shopping mall satisfaction and repurchase intention of fashion clothing consumers at this point in time when the mobile shopping has been routinized. To verify this, this study selected male and female university students with experiences in purchasing fashion clothing in mobile shopping mall within the last one year as its samples. For the verification of hypotheses, the factor analysis, multiple regression analysis, and simple regression analysis were conducted. The results of this study are as follows. First, the shopping tendencies of consumers who had experiences in mobile shopping included the economic shopping tendency, entertaining shopping tendency, convenient shopping tendency, and trend-pursuit shopping tendency. Second, the convenient shopping tendency, entertaining shopping tendency, and economic shopping tendency of consumers' mobile shopping tendencies had positive effects on the mobile shopping mall satisfaction and repurchase intention. Third, the information search for purchasing fashion clothing in mobile shopping mall had positive effects on the shopping mall satisfaction and repurchase intention.

현재 청강 게임 졸업작품 프로젝트에서 QA팀의 테스트 활동은 명세를 기반으로 진행된다. 하지만 대학의 게임 개발 프로젝트 특성상 체계적인 문서와 같은 테스트 베이시스를 확보하기 어렵다. 이렇게 부족한 명세를 기반으로한 테스트는 테스트할 게임의 전체를 커버하기 어렵다. 따라서 이를 보완하기 위해 리스크 기반의 탐색적 테스팅 접근법을 활용하여 조금 더 효율적인 테스트 전략 및 프로세스를 제시하고자 한다.

The purpose of this study was to investigate how the attributes of YouTube BJs, specifically those dealing in e-sports content, affects information usefulness, information search satisfaction, and behavioral intention. To achieve this purpose, data from 229 students collected by convenient sampling of college students were used for final analysis, and analyzed using SPSS 23.0 and AMOS 23.0 programs. The results of the study are as follows: First, the friendliness of the BJ had a significant positive (+) effect on the information usefulness, the information search satisfaction, and the behavioral intention. Second, it was found that the reliability of the BJ did not significantly affect the information usefulness, the information search satisfaction, and the behavioral intention. Third, the information usefulness had no significant effect on behavioral intention, but Information search satisfaction was found to have a significant positive (+) effect on behavioral intention. Therefore, the results of this study are expected to contribute to establishing a strategy for e-sports content production based on the attributes of BJs.

Network Centric Warfare(NCW) is becoming a prominent concept in the current trend of warfare. To support high quality communication between strategic/tactical units in the concept of NCW, Tactical Airborne Networks are likely to be constructed in the near future to take part in the NCW. In these Tactical Airborne Networks with dynamic topology variations due to very high mobility of participants nodes, more efficient and reliable neighbor discovery protocols are needed. This paper presents the adaptive HELLO message scheduling algorithm for Tactical Airborne Network using directional antennas. The purposed algorithm can reduce the overhead of periodic HELLO message transfer, while guaranteeing successful data transmission. We concluded a mathematical analysis and simulation studies using Qualnet 4.5 for evaluation the performance and efficiency of the proposed scheme.

This study explores the evolution of technical innovation over time. It focuses on sectors of the information technology because this industry can be referred to as one of the most dynamic industries of all times. Following evolutionary theorists, we argue that technological change is gradual and that superior firms and technologies are reward by the' selection' environment. In the initial phase of the industry life cycle, technological change is expected to be radical and uncertainty is high. Over time a product or technology is likely to arise which stands out above all other products or technologies. These so-called 'basic designs' serve as sorts of 'technological guideposts' for further developments in the technology. Once a basic design established, technological progress tends to follow consistent paths or trajectories. The cumulative character of technological progress facilitates a rapid expansion of the boundaries of the technology until the natural limits of the technology are approached and technological progress slows down. Following ecological theories, supply-side developments in the industry are described on the basis of five different organizational types. On the basis of this pattern of market and technological evolution we came up with seven basic propositions.
