In this study, we classified and analyzed the type and cause of resident conflicts and made a solution at side of resident through resident survey study for research subjects located at photovoltaic system will be installed or not. The factors of resident conflicts based on news media release from 2006 to 2018 were classified to four types such as economic, environmental, technological and procedural factors. According to the news analysis, the types and proportion of resident conflicts in the photovoltaic system projects showed 33% of economic factors, 32% of environmental factor, 21% of technological factor and 14% of procedural factor. This news analysis may suggest that it is very important residents to share the economic benefits as well as to ensure the fairness of the procedures for carrying out the project based on transparent information disclosure during the business promotion and profit distribution stages. We conducted the poll survey in the rural towns where photovoltaic system will be installed or not. The poll survey results showed that (i) there is quite difference in agreement rate and other recognition for sensitive matters such as profit distribution, environmental and technological factors whether photovoltaic system will be installed or not, (ii) the resident conflict regarding the photovoltaic system installation can reduce through direct involvement of residents process. To solve these resident conflicts, the local governments should mainly effort and consider the supporting technologies and consults to solve clearly resident conflicts. In addition, it has to advertise the safety of photovoltaic systems regarding electromagnetic wave which were within the range of scientifically harmless to the human body.

In this study, several experiments were designed to test the effectiveness of social media in export marketing. In particular, the experiments were made using Twitter and Facebook. The results showed that users' interest were able to increase the effects combined with B2B and B2C marketing events. The B2C marketing events could be made by personal target Event, Poll event, guest comments and social commerce. The B2B marketing was performed using Page Manager, Affiliate page, building and affiliate marketing group. Special features of Facebook such as social plug-in, Twitter integration, and Photo Tagging were found effective. A couple of implications were found in this study. First, the link between social media channel system was key success factor in effective export marketing. Second, the corporate marketing mix and social media consistent with the marketing mix strategy, communication between the managers and the managers' competencies were obtained for the key success factors.

Communication between Bluetooth devices is based on TDD by a master unit. In this discipline, the transmission of slave packets can be made only when the master transmits a packet to the slave. Thus, some slots may be wasted when there is no user data in the master's or slave's queue due to the transmission of a POLL or NULL packet. Therefore a scheduling scheme which can minimize the slot waste is required in Bluetooth intra-piconet communication. However, since the master is responsible for the intra-piconet scheduling, it must be provided with an information on each slave's queue length to apply traditional scheduling schemes. which is impossible in Bluetooth. This paper presents a new Bluetooth intra-piconet scheduling scheme that is efficient and does not require the information on each slave's queue length. The scheduling is done based on the information about the existence of data in the master and slave queues which is derived by the master identifying the type of packets transmitted. The master schedules to communicate with the slaves according to the priorities determined based on this information. We Presents simulation results which indicate a significant improvement in the performance when our proposed scheme is used.

The Common Criteria can be used as a guideline for one CCRA member to avoid re-evaluating IT security products which were already evaluated by other CCRA members. In this paper, we have analyzed the evaluated IT security products under CC scheme in several nations, such as Unite States, Great Britain and Australia. and defined new category of the IT security products for the domestic CC evaluation. And we have analyzed the domestic and international market on the information security products, have conducted a poll to receive opinions and demands of the Korean industries for Korea policy decision maker to select the possible IT security products which will be evaluated in Korea under CC scheme. As a conclusion, we have selected 15 IT products based on the response to a poll by the industries, the market size, the evaluation amount demanded by the user, manufacturer, and evaluator, to select the possible IT security product under CC schemes in Korea during next 5 years. Moreover, the characteristics, the benefit, and the demerit of the selected IT products were analyzed. This paper can be used as a guideline document for Korea policy decision maker to select the IT products to be evaluated under CC scheme in Korea for next 5 years.

In the customer-centered era, financial institutions have understood the importance of Customer Relationship Management(CRM), and heavily invested into building the required technology infrastructure more than ever. In a competitive environment that are changing fast, knowledge management is necessary. To know customers' needs and desire, we have to approach their environment and mind, and the method by estimating in terms of supposing or imitating. Applying customers' knowledge is effective and will come up with a stepping-stone to get rid of threatening factors by having competitiveness in a competitive environment and extending and changing the corporation. This purpose, the study has identified knowledge-oriented infra that corporations know and customer relations by conducting a poll of local corporations and have presented motives that can effectively carry out knowledge-based customer relations. To gain competitive advantage, these Institutions need to understand their customers' potential value to find out more and to recognize the significant changes of customer. Then the CRM implementation will help Financial Institutions move to more of a sales culture away from product and closer to the customer.

We compared and analyzed the relationship between vote intention, vote expectation, and party approval rate using the 19th Presidential Election and the 7th Nationwide Simultaneous Local Election (Regional Local Government Election) poll data. The case study provides an alternative method of predicting the winner using vote expectation and a party approval rate that can improve the accuracy of election forecasting.

IEEf 802.11 Point Coordination Function (PCF) mode is defined to support time bounded traffic, such as VoIP in wireless LANs. The poll scheduling plays an important role in IEEE 802.11 PCF mode operation. This paper proposed a Multicast Polling Scheme to increase the performance of wireless LANs. Moreover, we proposed a polling schedule scheme for our proposed multipoll to serve real-time traffic. The results show that the proposed mechanism is more efficient than the original IEEE 802.11 PCF.
