The MICE(Meeting, Incentive travel, Convention, and Exhibition) industry grows steadily. Especially, exhibition industry plays an important role as the effective sales and marketing tools. However, lots of studies have focused on the flow analysis of audience traffic, booth recommendation or formulaic interactions between audiences and contents in the exhibition hall. In this study, we proposed an intelligent Interactive system considering audience's response for providing personalized exhibition service. First, we extracted components of the system architecture through the previous studies. Second, we suggested the system architecture and scenarios for intelligent interactions between audiences and contents. We hope that the proposed system will strengthen the basis for implementing interactive system in the exhibition industry.

Because energy consumption of the construction part is very high, there is a growing need to introduce environment-friendly buildings. Therefore Green Building Rating System is enacted in Korea. Though environment-friendly factors such as green area affect the apartment housing price, there's no saying whether Green Building Rating System directly affect the apartment housing price. The purpose of this paper is to estimate the impact of Green Building Rating System on an apartment housing price. The analysis result demonstrated that Green Building Rating System don't affect the apartment housing price. This result means that there is a problem with the effectiveness of Green Building Rating System. The government ought to institute incentive program to ctivate the market of environment-friendly building.

It is very necessary to find how to develop international government procurement by analyzing functions and roles of information providing circumstance and existing total international government procurement information system. In addition, it would require to draw up a way of improving current international government procurement information system based on the problems of existing system. In this study, we analyze the current status of Korean international government procurement information system and give an idea of mutual cooperating with DGMARKET, a good example of international government procurement information system. As a practical method, cooperating with DGMARKET by building each countries' gateway will be very helpful in cost saving and providing information. It will also complement the limitation of Korean system's one way service. But supplying only international government procurement information is insufficient in realization of e-trade in international goverment procurement market. To settle these problems, treating international government procurement as a same field of trade and giving political support and incentive to company which hopes to participate international goverment procurement are absolutely needed.

Export controls on strategic items has been an international standard of trade. We should understand the global trend of this and perform clean policies in the international community. This article examines the Improvement of Competitiveness and International Export Control System of Strategic Items for focusing to Internal Compliance Program(ICP). Therefore, this study would like to suggest for build to ICP. Each member of company have to convert their perception for controling strategic items. Also, they have to build controling system in ERP system and extend Incentive for CPs. the support to the trustworthy controling system. Korea is actively trying to control strategic items export for world peace and national security. So the related enterprise needs to manage voluntary export system.

At present, European railways in U.K., Sweden, and Belgium have taken serious efforts to improve railway services by implementing a service evaluation system. Not only do they measure the service-related performance of a railway system, but also operate an incentive system according to the results of service-related performance. This performance evaluation system can be also used to provide basic data for other policies such as fares, subsidies and track user charges etc. After the restructuring process of Korean national railways, therefore, although it is expected to face many difficulties in the future, it is desirable to implement a performance evaluation system for securing the long-term growth of Korean railway industry.

The Myanmar rice cycle's existing system is still relying on a third party to manage every rice data information from several organizations. It is inconvenient to supervise simultaneously due to the unreliability of information provided by organizations. Thus, the rice cycle's original data is challenging to be utterly trusted since irresponsible parties can manipulate the current state of information. Moreover, the applied system does not preserve a proper incentive for the involved parties. In this paper, we leverage the Ethereum blockchain to be adopted to tackle the aforementioned issues. The main objective is to build trust between parties in the Myanmar rice cycle system. Our proposed scheme allows customers to check and trace information about the rice cycle information without worrying about the integrity of the data. Furthermore, the authorized parties are also rewarded by the government through Ethereum smart contract features. Eventually, our scheme achieves traceability in the rice chain system and leads to the complete digitization and automation of the rice cycle information.

Biogasification is a technology that produces environmentally friendly fuel using methane gas generated in the process of stably decomposing and processing organic waste. Biogasification is the most used method for energy conversion of organic waste with high moisture content, and is a useful method for organic waste treatment following the prohibition of direct landfill (2005) and marine dumping (2013). Due to African Swine Fever (ASF), which recently occurred in Korea, recycling of wet feed is prohibited, and consumers such as dry feed and compost are negatively recognized, making it difficult to treat food waste. Accordingly, biogasification is attracting more attention for the treatment and recycling of food waste. Korea's energy consumption amounted to 268.41 106toe, ranking 9th in the world. However, it is an energy-poor country that depends on foreign imports for about 95.8% of its energy supply. Therefore, in Korea, the Renewable Energy Portfolio Standard (RPS) is being introduced. The domestic RPS system sets the weight of the new and renewable energy certificate (REC, Renewable energy certificate) of waste energy lower than that of other renewable energy. Therefore, an additional incentive system is required for the activation of waste-to-energy. In this study, the operation of an anaerobic digester that treats food waste, food waste Leachate and various organic wastes was confirmed. It was intended to be used as basic data for preparing the waste-to-energy incentive system through precise monitoring for a certain period of time. Four sites that produce biogas from organic waste and use them for power generation and heavy gas were selected as target facilities, and field surveys and sampling were conducted. Basic properties analysis was performed on the influent sample of organic waste and the effluent sample according to the treatment process. As a result of the analysis of the properties, the total solids of the digester influent was an average of 12.11%, and the volatile solids of the total solids were confirmed to be 85.86%. BOD and CODcr removal rates were 60.8% and 64.8%. The volatile fatty acids in the influent averaged 55,716 mg/L. It can be confirmed that most of the volatile fatty acids were decomposed and removed with an average reduction rate of 92.3% after anaerobic digestion.

In this paper, we analyze an M / M / 1 queueing system where there are incentive conflicts among customers. Self-interested customers' decisions whether to join the system or not may not necessarily induce a socially optimal congestion level. As a way to alleviate the over-congestion, toll imposition was used in Naor's paper [3]. Instead of using a toll mechanism, we study the usefulness of imperfect information on system state (queue size, for example) as a way to reduce the over-congestion by self-interested customers. The main conclusion of this paper is that by purposefully giving fuzzy or imperfect information on the current queue size we can improve the congestion in the system. This result might look contradictory to rough intuition since perfect information should give better performance than imperfect information. We show how this idea is verified. In deriving this result, we use the concept of Nash equilibrium (pure and mixed strategy) as introduced in game theory. In some real situations, using imperfect information is easier to apply than imposing a toll, and thus the result of this paper has practical implications.
