  • Due to the growing activity of online communities recently, its influence is gradually growing. Furthermore, it also has a huge effect on corporations in establishing their marketing strategy. One important aspect that occurs is that there is a high possibility that the interest of online community members, which was first organized because of a common interest, will be similar. Thus, there is a growing desire to share information and knowledge that would be mutually useful among them. Therefore, this study aims at revealing the motivation factors on why such knowledge sharing behavior occurs among online community members that are voluntarily organized. The detailed objectives of this survey is to first conduct qualitative research on online community members, and then to examine what are the motivation factors that cause knowledge sharing behavior among online community members. Second, by developing questionnaires according to the analyzed contents of the qualitative research results, the reliability and feasibility of such questions are to be verified. As a result, new motivation factor of knowledge sharing which was not suggested in the existing studies because of characteristics of online community was revealed. If the results of existing related studies and those of this study are compared, the six factors such as desire of showing off, awareness, perceived benefits, pleasure, challenge and sense of belonging except for motivator such as sense of achievement and compensation, trust are newly discovered motivators of knowledge sharing behavior.

  • As open source can reduce costs and apply to various fields rapidly, many countries have actively adopted open source. However, geo-spatial open source in Korea is not actively promoted yet comparing to other countries having similar infra environments. In this study, we analyzed the perception of geo-spatial open source, utilization status, the development possibility and future direction using questionnaire survey completed by experts dealing with spatial information. The survey result shows that many experts have experiences of using geo-spatial open source but they got a lack of understanding about open source license or regulations and only a few people got professional training. Insufficient references, the difficulty of maintenance, lack of support and low technical reliability have hindered the adoption of geo-spatial open source. Only some part of geo-spatial open source software or libraries in some field have been used in the country. However, many researchers rate highly development potential and plan to use geo-spatial open source soon. If user's convenience, reference materials, technical trust and policy support are improved, open source field for spatial information will be developed greatly in the future.

  • The purpose of this study is to demonstrate, through case studies, the usefulness of utilizing local R&D centers under science and technology ODA programs. For the past few decades, advanced countries have supported ODA projects of developing countries, but there have been negative opinions regarding the results. Through a case study of the black pearl cultivation project between the Korea Institute of Ocean Science & Technology and Micronesia, this study explains the usefulness of actively utilizing Korean R&D centers established and operational in recipient countries. Although black pearl cultivation is not an ODA project, the case study offers valuable insights as it is operated in a similar form and thus highly applicable to future projects. Based on the case study, four implications were derived to ensure the successful operations of science and technology ODA projects in the future. First, there is a need to improve relevance by making use of the technological capacities of local R&D institutes to develop projects that reflect the needs of recipient and donor countries. Second, trust must be established with local communities over the long term in order to enhance the effectiveness and efficiency of project operations. Third, the proportion of science and technology ODA projects must be expanded to acquire sustainability, and more support should be granted to ODA projects involving marine resources, which are an advantage for countries of Micronesia. Lastly, the locals should be offered employment opportunities and regular training programs to allow for the actual transfer of knowledge instead of mere techniques. The implications derived in this study will prove useful in pursuing science and technology ODA projects, especially with Micronesia.

  • This study aimed to assess the rental housing ABS in Korea, and to suggest ways of improving the structure of existing rental housing ABS. Thus, the three major assessment for existing public rental housing ABS case can be summarized as follows : First, when viewed in terms of the accounting treatment, rental housing ABS which use the future receivables as underlying asset, can not enjoy off-balance-sheet effect. Second, when viewed from the point of financing costs, the rental housing ABS interest rate being higher than unsecure bond is very unreasonable nevertheless the ABS being off-balanced. Third, when viewed from the liquidity effect, the originator (LH) use the ABS as a means of diversifying funding in a serious liquidity crisis situation. The Improvement of rental housing ABS based on the evaluation results can be summarized into two broad. First, it is a plan to handle the off-balance-sheet effect in a way of changing the accounting treatment of rental payment. Second, it is a plan to reducing the structuring cost and interest rate in ways of multi-asset securitization structure, self-trust structure, and adopting legal CB structure.

  • The evolution of IT facilitated the communication and knowledge sharing between the social network service (SNS) users. When the more information about SNS users had been posted in SNS site, SNS users had sometimes exposed in the risk of privacy invasion. To remedy this problem, we had introduced the information control mechanisms from the prior studies in data management to the SNS area and empirically validated the effect of these mechanisms in this research. Three information control mechanisms had been elected as access control, reference control and diffusion control. We had conducted a survey to the Facebook users which is the most famous SNS site. 459 data had been gathered and analyzed by PLS algorism. As the results, reference control and diffusion control has significantly increased the trust on SNS providers and decrease the privacy concern. This change could significantly affect on the satisfaction with the SNS site and knowledge sharing intention of SNS users. This study could introduce the new perspective about privacy protection issues in SNS area. Also, the information control mechanisms suggested in this study could contribute to make more robust privacy protection mechanisms in SNS site in practice.

  • The United Nations Climate Change Conference, Durban 2011, ended on December 12, 2011, 36 hours over its schedule, delivering the Durban Package, which consisted of, inter alia, the extension of the period for Kyoto Protocol term and the launch of Ad-hoc working Group on the Durban Platform for Enhanced Action. Despite the positive progress made in Durban, the future of post-2012 climate regime still seems cloudy. Before the Durban conference, some of Annex I countries with emissions reduction commitment under the Kyoto Protocol's first commitment period openly declared their intention not to participate in the second one, reducing the effectiveness of Durban agreement. Parties to the conference have a long list of difficult issues disturbing the materialization of the new legal agreement in 2020 such as level of mitigation targets of individual countries and legal nature of their commitment. Given this uncertainty, the Korean government should reinforce its domestic climate policies rather than settling in the fact that it remains as a non-Annex I county party under the Durban Agreement due to the extension of the Kyoto Protocol period. Domestically, it needs to continue to raise the public awareness for rigorous climate policies to transit its economy to low carbon pathway which reduces the country's dependency on fossil fuel in the long term. It is also important to implement cost effective climate policies to cope with domestic resistance and international competitiveness. Internationally, its priority would be working for trust-building in the on-going negotiation meetings to encourage meaningful participation of all parties.

  • A Volunteer Fire Brigade is a voluntary social services organization that performs various assistance works in fire fighting activities such as fire fighting and rescue of human lives on a part-time basis. Recently, it has also assumed an important role in the creation of security culture of local society. Besides, it provides diverse service activities related to security of local society. However, as this kind of volunteer fire brigade organization is not in a vigorous state, research for an improvement is being carried out in earnest. As part of a vitalization plan of the volunteer fire brigade, an attempt was made in this research to present an activation plan of the volunteer fire brigade through formation of social capital. Accordingly, efforts were made in this research to investigate and analyze an awareness of social capital among the volunteers and to present on this basis a plan for formation of social capital for the volunteer fire brigade of local society. As a result of the research, it turned out that social norm has the major effect on the formation of social capital for volunteer fire brigade. Therefore, it is our belief that an independent statute should be established to nurture and develop volunteer fire brigades. And when strong mutual trust among the volunteers are formed and efforts for devotion to local society are made on this basis, the security level of local society will be enhanced further.

  • The contracting parties must be provided a litigation scheme in order to resolve a dispute. This means taking advantage of effective measures for mediation or arbitration. A lease transaction is likely to occur mainly after a dispute. It is necessary to take the appropriate measures in advance. In general, when a variety of contracts are created, conflicts arise and disputes have to be resolved through mediation and arbitration documents, and adjustment or intervention is called for. Arbitration system is a system that is established based on the trust of the arbitral tribunal. For such system, quality education for enhancing professionalism required of the arbitrator is important. A party responding to an arbitration agreement presents a problem. The current system must ensure that there are no disadvantaged parties. However, a party must depend on an arbitration agreement that is part of the law rescue system. A litigation support by the local Bar Association must be carried out. It should be notified of the contents of the contract to select a strategy that will best resolve the conflict. In the case of lease transactions, there is a need to create a scheme to make a standard agreement that inserts an arbitration clause. Lease sale and purchase agreement or lease agreement is a form of contract that has been frequently used. Here, the arbitration agreement clause for a lawyer that will serve as arbitrator should be inserted. It is a scheme that can be activated for individuals in poor areas. In addition, it is possible to see it taking a scheme to take advantage of the lawyer system for the future of the town. The Attorney System of a town is a system that the Korean Bar Association, Legal Department has put in place since 2013. If a real estate trade dispute occurs, the role of the intermediary attorney should be to carry out his duties efficiently. In the case of real estate transaction conflicts, the lawyer of the village should be registered as the arbitrator. It is important to establish a basis of regulations through this type of real estate transaction accident analysis. Before proceeding with various adjustment systems, it is desirable to expand the arbitration region. Now we need a realtor amendment. It is the part where fragmentation of intermediary qualification is required, along with the eligibility of a subdivision.

  • ZnO has nanostructured material because of unique properties suitable for various applications. Amongst all chemical and physics methods of synthesis of ZnO nanostructure, the hydrothermal method is attractive for its simplicity and environment friendly condition. Nanostructure ZnO thin films have been successfully synthesized on fluorine doped tin oxide (FTO) substrate using hydrothermal method. A possible growth mechanism of the various nanostructures ZnO is discussed in schematics. The prepared materials were characterized by standard analytical techniques, i.e., X-ray diffraction (XRD) and Field-emission scanning electron microscopy (SEM). The XRD study showed that the obtained ZnO nanostructure thin films are in crystalline nature with hexagonal wurtzite phase. The SEM image shows substrate surface covered with nanostructure ZnO nanrod. The UV-vis absorption spectrum of the synthesized nanostructure ZnO shows a strong excitonic absorption band at 365 nm which indicate formation nanostructure ZnO thin film. Photoluminescence spectra illustrated two emission peaks, with the first one at 424 nm due to the band edge emission of ZnO and the second broad peak centered around 500 nm possibly due to oxygen vacancies in nanostructure ZnO. The Raman measurements peaks observed at $325cm^{-1}$, $418cm^{-1}$, $518cm^{-1}$ and $584cm^{-1}$ indicated that nanostrusture ZnO thin film is high crystalline quality. We trust that nanostructure ZnO material can be effectively will be used as a highly active and stable phtocatalysis application.

  • Countries across the globe, including those in Europe, are waging a "war against terrorism" as international terrorist groups such as ISIS and lone-wolf terrorists have unleashed various large-scale attacks on rail infrastructure. Anti-South Korean sentiment exists in Muslim-majority countries because the nation has cooperated with the US for its military interventions in the Middle East, and ISIS has threatened to target South Korea four times since September 9, 2015. In addition, North Korea has been left isolated in the international community with its missile and nuclear tests, while further escalating inter-Korean tension and threatening to strike major facilities and attack important figures in the South. These situations imply that South Korea is no longer immune to terrorist attacks. If the nation fails to prevent or deter such terrorist attacks against rail networks, massive casualties, property damage and social confusion would be unavoidable, deteriorating national and international trust in its counter-terrorism policies. This may lead to a national crisis involving decreases in the number of tourists, dampened interest of foreign investors, and capital flight. This study aims to propose policy measures to enhance railroad security checks, based on the work of railroad police officers, for the sake of protecting citizens and public safety. The suggestions include an incremental expansion of railroad security checks; growth of the railroad police force and adjustment of their policing distribution with other police officers; enhancement of security systems across important rail networks; improvement of the Railroad Safety Act; Southeast Asia, including the corresponding strengthening of the national crackdown illegal immigrants, and plans for pre-emptive and regular cooperation among organizations related to the promotion of security checks and the prevention of terrorist attacks.
