In the midst of dynamic industrial changes, companies need data analysis considering the effects of integration of various technologies in order to establish innovative R & D strategies. However, the existing technology forecasting model evaluates individual technologies without considering relationship among them. To improve this problem, this study suggests a new methodology reflecting the integration of technologies. In the study, a technology forecasting indicator was developed using the technology integration index based on social network analysis. In order to verify the validity of the proposed methodology, 'drone task performance technology' based on patent data was applied to the research model. This study aimed to establish a theoretical basis to design a research model that reflects the degree of integration of technologies when conducting technology forecasting research. In addition, this study is meaningful in that it quantitatively verified the proposed methodology using actual patent data.

Cyberbullying has been an emerging issue in recent years where research has revealed that users generally spend an increasing amount of time in social networks and forums to keep connected with each other. However, issue arises when cyberbullies are able to reach their victims through these social media platforms. There are different types of cyberbullying and like traditional bullying; it causes victims to feel overly selfconscious, increases their tendency to self-harm and generally affects their mental state negatively. Such situations occur due to security issues such as user anonymity and the lack of content restrictions in some social networks or web forums. In this paper, we highlight the existing solutions, which are Intrusion Prevention System and Intrusion Detection System from a number of researchers. However, even with such solutions, cyberbullying acts still occurs at an alarming rate. As such, we proposed an alternative solution that aims to prevent cyberbullying activities at a younger age, e.g., young children. The application would provide an alternative method to preventing cyberbullying activities among the younger generations in the future.

In this digital age, all organizational environments force businesses to adopt Information and Communication Technologies (ICT) since these technologies have immense impact on such businesses' competitiveness and productivity. Nonetheless, the productivity and the competitiveness enjoyed by such firms vary depending on the size or the organizations, context of the country; developing or developed, and what kinds of technologies are adopted. This investigation focused on small- and medium-sized enterprises (SMEs) of Eastern province of Sri Lanka where such studies are scanty. The adoption of social media (SM) by SMEs is inclined to change how organizations operate, this calls for an investigation of the elements that impact SMEs to adopt SM and such investigation. Technology-Organization-Environment (TOE) framework was based to understand the factors. Research approach was quantitative approach using questionnaire survey. Data were collected using online form to see 285 valid responses. Structural Equation Modelling was deployed to evaluate the proposed model. Results revealed that Relative Advantage, Compatibility, Complexity, Observability, Competitive Intensity, Bandwagon Pressure, and Competitive Pressure were influencing, while Trialability, Top Management Support, CEO's Innovativeness did not show statistically significant influence on SMEs' social media adoption.

Purpose This study collects data of the recently activated online black market and analyzes it to present a specific method for preparing for a hacking attack. This study aims to make safe from the cyber attacks, including hacking, from the perspective of individuals and businesses by closely analyzing hacking methods and tools in a situation where they are easily shared. Design/methodology/approach To prepare for the hacking attack through the online black market, this study uses the routine activity theory to identify the opportunity factors of the hacking attack. Based on this, text mining and social network techniques are applied to reveal the most dangerous areas of security. It finds out suitable targets in routine activity theory through text mining techniques and motivated offenders through social network analysis. Lastly, the absence of guardians and the parts required by guardians are extracted using both analysis techniques simultaneously. Findings As a result of text mining, there was a large supply of hacking gift cards, and the demand to attack sites such as Amazon and Netflix was very high. In addition, interest in accounts and combos was in high demand and supply. As a result of social network analysis, users who actively share hacking information and tools can be identified. When these two analyzes were synthesized, it was found that specialized managers are required in the areas of proxy, maker and many managers are required for the buyer network, and skilled managers are required for the seller network.

There have been many requests for development of senior housing in Korea. Therefore it was very important to review how senior houses are established and managed in other countries. In this point, this research compared the actual conditions of the homes for the elderly in the U.K, U.S.A and Japan. Through the process, this research aimed to find the implications for Korea. The research was conducted by the literature review on senior congregate housing with Franklin's(1998) social constructionism perspective. This kind of research might be utilized as a theoretical framework for performance of any systems of housing for the aged. In this study, the researchers suggested the implications of senior congregate housing as follows. Firstly, in terms of structural context, government in the U.K, U.S.A., and Japan were positively concerned with solving the housing problems for senior citizens despite some differences. Secondly, from an institutional context, institutions related with provision, construction, and management of senior congregate housing were systematically consolidated and they all adapted the housing and welfare policy. Thirdly, in organizational context, there was an organization in charge of provision and management that exclusively oversaw the housing for the elderly in both the public and private sectors. Fourthly, in operational context, standards regarding space were clearly set both for individual units and common spaces as well as for facilities and services for the residents. Finally in terms of intersubjective context, the competency of housing manager and ways to involve the families which were important for residents' independent life were under study.

The task network which is formed of different individuals can be recognized as a social network. Therefore, the way to communicate with people inside or outside the network has considerable influence on their outcome. Moreover, the position on which a member stands in a network shows the different effects of the information systems supporting communication with others. In this paper, it is to be studied how personal CMC (computer-mediated communication) tools affect the mission that those who work for a network perform through diverse task networks. Especially, we focused on synchronicity of CMC. On this score, the perspective of Media Synchronicity Theory was taken that had been suggested by criticizing Media Richness Theory. It is the objective, from this perspective, to find which characteristics of networks make the value of IT supporting synchronicity high. In the research trends of social networks, there have been two traditional perspectives to explain the effect of network: embeddedness and diversity ones. These differ from the aspect which type of social network can provide much more economic benefits. As similar studies have been reported by various researchers, these are also divided into the bonding and bridging views which are based on internal and external tie, respectively, Size, density, and centrality were measured as the characteristics of personal task networks. Size means the level of relationship between members. It is the total number of other colleagues who work with a specific member for a certain project. It means, the larger the size of task network, the more the number of coworkers who interact each other through the job. Density is the ratio of the number of relationships arranged actually to the total number of available ones. In an ego-centered network, it is defined as the ratio of the number of relationship made really to the total number of possible ones between members who are actually involved each other. The higher the level of density, the larger the number of projects on which the members collaborate. Centrality means that his/her position is on the exact center of whole network. There are several methods to measure it. In this research, betweenness centrality was adopted among them. It is measured by the position on which one member stands between others in a network. The determinant to raise its level is the shortest geodesic that represents the shortest distance between members. Centrality also indicates the level of role as a broker among others. To verify the hypotheses, we interviewed and surveyed a group of employees of a nationwide financial organization in which a groupware system is used. They were questioned about two CMC applications: MSN with a higher level of synchronicity and email with a lower one. As a result, the larger the size of his/her own task network, the smaller its density and the higher the level of his/her centrality, the higher the level of the effect using the task network with CMC tools. Above all, this positive effect is verified to be much more produced while using CMC applications with higher-level synchronicity. Among the a variety of situations under which the use of CMC gives more benefits, this research is considered as one of rare cases regarding the characteristics of task network as moderators by focusing ITs for the operation of his/her own task network. It is another contribution of this research to prove empirically that the values of information system depend on the social, or comparative, characteristic of time. Though the same amount of time is shared, the social characteristics of users change its value. In addition, it is significant to examine empirically that the ITs with higher-level synchronicity have the positive effect on productivity. Many businesses are worried about the negative effect of synchronous ITs, for their employees are likely to use them for personal social activities. However. this research can help to dismiss the concern against CMC tools.

본 두 편의 연속논문은 수도권과 비수도권의 갈등관계를 조절하고 상생전략을 구체적으로 실현하기 위한 수단으로서 수평적 지방재정조정제도 이용방법을 제시한다. 본 논문에서는 먼저 수도권 정책을 둘러싼 선행연구를 비판적으로 검토한다. 수도권의 경제적 이점, 정책방향 및 대도시권의 역할 등을 둘러싸고 양극단의 대립적 견해가 구조적으로 고착화 되고 있지만 상생발전에 대해서는 수사적 제시만 있을 뿐 구체적인 실천수단을 제시하지 못하고 있다. 하나의 대안으로서 한국에서 아직 도입하지 않고 있지만 동일 수준의 지방정부간 재정이전을 동반하는 수평적 지방재정조정제도는 효과적인 상생발전 구현수단이 될 수 있다. 독일, 영국, 프랑스, 스웨덴을 중심으로 외국의 수평적 지방재정조정제도의 기본이념과 논리적 준거 및 조정방법을 살펴보고, 한국 지역정책에 갖는 시사점을 제시한다.

본 연구는 소셜 미디어 상 다양한 행위 중에서 '좋아요'를 누르는 행위가 의미하는 바를 감정적, 사회적으로 분석하여 그것이 소셜 미디어에 대한 전반적 태도에 어떠한 영향을 미치는 지, 또한 그 영향력이 성별에 따라 어떻게 달라지는 지 살펴보았다. 구체적으로, '좋아요'라는 행위에 담긴 의미를 감정적인 동감 측면과 사회적인 지지 측면으로 구분한 후, 그 의미를 지각하는 강도가 '좋아요'를 통해 이루고자 하는 단기적 목표 두 가지-관계의 강화 및 정보의 공유-와 소셜 미디어 사용에 대한 전반적 태도에 어떠한 방식으로 영향을 미치는 지 살펴보았다. 또한 여성의 경우 감정적 동감에서 관계 강화로 진화하는 과정이 더 강한 연관성을 보이며 남성의 경우 사회적 지지에서 정보 공유로 이어지는 과정이 더 강할 것이라 가정하였다. 285명의 소셜 미디어 사용자들을 대상으로 설문을 실시한 결과, 행위 관련 총 16개의 가설 중 10개가 채택되어 '좋아요'를 누르는 행위에 부여하는 의미의 강도에 따라 소셜 미디어 사용 태도가 어느 정도 달라지는 것이 확인되었으며 성별 차이의 경우 16개의 가설 중 의미에서 목적으로 이어지는 과정에서만 4개가 부분적으로 채택되어 성별 차이는 존재하지만 크지는 않은 것으로 나타났다. 본 연구는 '좋아요'를 단순히 양적으로만 이해하고 분석하는 것이 아니라 그 행위 안에 담긴 다양한 감정 및 기대를 규명하였다는 점에서 의의가 있다.

This research purposed to analyse the diversity of the long-term care system based on the dependency/independency of the aged. For this purpose, we divided the long-term care systems to three components; form of benefit, generosity of benefit and delivery system. Form of benefit is whether the benefit is cash or in-kind, and the generosity of benefit is related to the level and coverage of benefit. The last concerned to focus on provider and user selection. According to this, we tried to make an ideal type of long-term care in the perspective of citizenship and consumerism. As a result, we established four types of long-term care system; active citizen type, passive citizen type, latent citizen type, and family dependent type. And we investigated Austria, Sweden, Germany and Korea for each type empirically.
