The definition of digital poverty has not been changed since it was used at the first digital divide survey in 2000s. The objective of this study is to reexamine and redefine digital poverty targets of digital divide survey. This study examines the present state for the target of the digital divide survey focusing on Disabilities, Low-Income and Elders and then redefines digital poverty for them. The results suggest to reexamine 15 types of disabilities by the revised the Disabled Welfare Law as digital divide targets, rather than limiting to physical, brain, hearing and visual disabilities. For the low-income target, people on the second-to-the bottom income bracket as well as those on basic welfare should be included as the target of low-income people for digital poverty. The age of the elder target for digital poverty should be adjusted to sixty-five or more in the era of aging population.

Internal and external environment changes surrounding our society are pressing our government to solve a lot of difficult problems. These problems are more likely to be solved by a number of ministries and agencies, rather than a single ministry or agency. Thus collaboration is a necessary strategy to increase government's problem-solving skills. This study examines determinants of successful collaboration by analysing cases of local governments that solved uneasy problems covering many ministries after persistent efforts which have been controversial issues in our society. First, theoretical approach for collaboration and its matrix is examined. Second, interviews of government officers are analyzed to study collaboration cases. Finally, Strategic points of view are discussed to promote collaboration within government sectors. The results show that common goal sharing, incentives and supporting systems play important roles in inducing collaboration.

The purpose of this article was to not only review historically the growth and development of dancesport, to but also seek to inform the value and prospect of dancesport in Korea. To achieve the purpose of the paper, the result of this article was framed into four time periods for a historical review of Korean dancesport growth and development: the late 1880s - the mid 1940s, the late 1940s - the late 1980s, 1990s and 2000s onwards. First, the first period was from the late 1880s to the mid 1940s when the nation accepted a social dance and western dance and tradition especially in upper-class Korean society. Second, the second period was from the late 1940s to the late 1980s when social dances (or ballroom dance) were suppressed under the military-based regime. The most likely explanation for this was a tradition that Korea society consider distinction between the sexes as a virtue. Third, third period was the 1990s when the social dance (ballroom dance) was developed officially into dancesport. Actually, the 1990s saw the sport built up a positive image while a negative image was portrayed by the military-based government. Fourth, the fourth period was the 2000s onwards when the sport has been developed as a sport and culture in a sound and systematic manner. Indeed, the sport has come to meet the public tastes.

Nowadays, team members often use mobile messenger service (MMS) in performing team projects. Team members can freely express their ideas or opinions using MMS without any restrictions in terms of place and time. But, in team project, using MMS is pressing them to perform their project more quickly than off-line conference, and assigning a role outside the range of their ability. In other words, team members can recognize work overload by utilizing MMS and this work overload can lead to team conflict. This study examines the effect of work overload through MMS use on team performance. We consider team engagement and team trust as the key drivers of team performance. However, team conflict will obstruct team engagement and team trust. Research model was analyzed by 135 university students who were doing several team projects. The analysis results show that work load through MMS use has a significant effect on team conflict. In other words, when work load is increased by utilizing MMS, it leads to team conflict. This team conflict loses trust between team member and hinders team performance. Lastly, this research provides several implications for right usage of MMS to improve team project performance.

DOI : 10.14400/JDC.2016.14.3.181
With regard to CSR, Proactive CSR has been less researched in small and medium enterprises(SMEs). This study examines empirically the association between SME's organizational capabilities, proactive CSR and performance as well as a moderating role of perceived uncertainty between capabilities and proactive CSR. Using quantitative data collected from sample of 485 SMEs in Korea, we find that all specified capabilities are positively associated with adoption of proactive CSR by SMEs and that proactive CSR is, in turn, associated with an improvement in firm performance. In addition, we also find a mediating role of proactive CSR on the association between capabilities and performance as well as a moderating role of perceived uncertainty between capabilities and performance. The study is likely to contribute to SME's CSR strategy.

The number of multicultural families is on the rise worldwide. In this respect, the central government and municipal governments are also implementing and supporting multicultural-related policies. However, they are in progress, not as services needed for multicultural members but as policy issues. This causes multicultural members to fail to figure out the need of policies supported by the government or local governments, as well as to grasp the desire for what services in need are. In addition to this, many studies regarding multiculture are under way but few studies have been known so far as to multicultural business models. This study has suggested a final business model and strategy methods by designing, comparing and analyzing a business model needed for multicultural members through interviews with professionals and multicultural members with regard to mulcultural policies and examples in Korea.

Knowledge map is widely used to represent knowledge in many domains. This paper presents a method of integrating the national R&D data and assists of users to navigate the integrated data via using a knowledge map service. The knowledge map service is built by using a lightweight ontology modeling method. The national R&D data is integrated with the research project as its center, i.e., the other R&D data such as research papers, patent, and project reports are connected with the research project as its outputs. The lightweight ontology is used to represent the simple relationships between the integrated data such as project-outputs relationships, document-author relationships, and document-topic relationships. Knowledge map enables us to infer the further relationships such as co-author and co-topic relationships. To extract the relationships between the integrated data, a RDB-to-Triples transformer is implemented. Lastly, we show an experiment on R&D data integration using the lightweight ontology, triples generation, and visualization and navigation of the knowledge map.

DOI : 10.14400/JDC.2016.14.3.261
As IoT technology has gained the attention all around the world, the development for various services of healthcare, smart city, agriculture, and defense based on IoT is in progress. However, it is likely that healthcare services based on IoT have a problem of being leaked of patients' biological information by a third party and that risks patients' lives. In this paper, an IoT health care service managing model based on location sensor is proposed, which secures the biological information of a patient and simplifies the procedure to process the treatment and administration steps by using the data resources sensed. Even when an emergency occurs, this proposed model can respond quickly using the location information of the patient, which enables the staff in the hospital to locate the patient in real time. In addition, there is an advantage to minimize the time and the process of care, because the location of the equipment for necessary treatment is possible to be instantaneously located with attached sensors.
