Exchange of information is essential to the process of innovation such as product development. However, in many cases innovation fails because of a lack of knowledge sharing among parties concerned, even if parties individually have pieces of useful knowledge and skills. Besides physical factors like communication costs, the possibility of opportunistic behavior by parties like stealing ideas can discourage information exchange. This paper introduces a model to analyze incentives of information exchange. The model is a game by two players who alternately opt to offer information to the partner. It is suggested that information exchange can stop before reaching the efficient level. In order to attain the efficient information exchange, expectation of mutual benefit and absence of opportunistic motives in both players are needed. Methods for promoting information exchange include modifying payoff structure to meet the condition of information exchange. The fluidity of partnership may increase a variety of information exchange partners, but discourage building trust between partners which promotes information exchange.

The standardized and open information model called common language and information exchange format should be firstly defined for the interoperable power system and two-way information exchange among the components of the power system. The information models and information exchange formats for power facilities and power system applications are being defined in power system area, but the information model and information exchange format for the consumer area are not being yet defined besides of metering information model. An architecture and open standard for the information exchange between energy service provider and consumer are required to provide various value added services through the networking with devices in consumer premise. In this paper, an architecture for the two-way communications between energy service provider and consumer is defined and psXML(power system XML) for the information exchange is designed.

Countries around the world have been engaging in automatic exchange of information to tackle tax evasion. The same goal became the basis of the enactment of the Foreign Account Tax Compliance Act (FATCA) by the United States Congress. In order to establish a common approach to counter tax evasion among different countries, the Organization of Economic Cooperation and Development (OECD) released the Standard for Automatic Exchange of Financial Account Information in Tax Matters which consists of the Competent Authority Agreement (CAA) and the Common Reporting Standard (CRS). Specifically, the automatic exchange of information is the exchange of financial account information between Tax Authorities in relevant countries. The law requires this information to be collected by financial institutions around the world for reporting to Tax Authorities. Automatic exchange of Information is made up of two information sharing frameworks: The Foreign Account Tax Compliance Act (FATCA) and The Common Reporting Standard (CRS). Under the automatic exchange of information, all financial institutions must identify accounts held by customers who are foreign tax residents or entities connected to foreign tax residents. Financial institutions must report these to the relevant Tax Authority who will then automatically exchange the account information with the relevant foreign Tax Authorities. Korean government has enacted domestic laws to require financial institutions to collect and report this information and has entered into international agreements to exchange the information with other governments. This paper analyzed the FATCA and CRS rules overall and proposed solutions for the legal and practical issues. This paper contributes to the existing literature on the automatic exchange of information by considering two information sharing frameworks.

In the Korean domestic construction field, there are a lot of problems related to construction information exchange and sharing owing to the absence of construction drawing information exchange standard. To remedy the aforementioned inefficiency effectively, it is necessary to apply the STEP standard which is known as an international standard for achieving the establishment of Construction CALS. This study focus on suggesting a methodology to activate the STEP based construction drawing information exchange standard to the current construction drawing information exchanging and sharing practice. In this paper, the domestic and foreign standardization projects related to the construction drawing information have been investigated and analyzed. In addition, a methodology of applying and activating the STEP standard has been suggested. Finally, a verification and certification methodology for applying the CALS/EC construction drawing information exchange standard(STEP) have been suggested.

For effective battlefield situation awareness and command resolution, information exchange without seams between systems is essential. However, since each system was developed independently for its own purposes, it is necessary to ensure interoperability between systems in order to effectively exchange information. In the case of our military, semantic interoperability is guaranteed by utilizing the common message format for data exchange. However, simply standardizing the data exchange format cannot sufficiently guarantee interoperability between systems. Currently, the U.S. and NATO are developing and utilizing information exchange models to achieve semantic interoperability further than guaranteeing a data exchange format. The information exchange models are the common vocabulary or reference model,which are used to ensure the exchange of information between systems at the content-meaning level. The information exchange models developed and utilized in the United States initially focused on exchanging information directly related to the battlefield situation, but it has developed into the universal form that can be used by whole government departments and related organizations. On the other hand, NATO focused on strictly expressing the concepts necessary to carry out joint military operations among the countries, and the scope of the models was also limited to the concepts related to command and control. In this paper, the background, purpose, and characteristics of the information exchange models developed and used in the United States and NATO were identified, and comparative analysis was performed. Through this, we intend to present implications when developing a Korean information exchange model in the future.

Forecasting exchange rate movements is a challenging task since exchange rates impact world economy and determine value of international investments. In particular, Korean-U.S. exchange rate behavior is very important because of strong Korean and U.S. trading relationship. Neural networks models have been used for short-term prediction of exchange rate movements. Least squares support vector machine (LS-SVM) is used widely in real-world regression tasks. This paper describes the use of LS-SVM for short-term and long-term prediction of Korean-U.S. exchange rate.

The key exchange protocols are very crucial tools to provide the secure communication in the broadband satellite access network. They should be required to satisfy various requirements such as security, key confirmation, and key freshness. In this paper, we present the security functions in ETSI(European Telecommunications Standards Institute), and analyze the specification of the security primitives and the key exchange protocols for the authenticated key agreement between RCST(Return Channel Satellite Terminal) and NCC(Network Control Centre). ETSI key exchange protocols consists of Main Key Exchange, Quick Key Exchange, and Explicit Key Exchange. We analyse the pros and cons of key exchange protocols based on performance analysis and performance evaluation.

In this paper, we propose the effective exchange-method of a user profile for adapted contents services in the contents adaptation system. The profiles continuously exchange among the devices of contents adaption system for providing the adapted contents to a user. The profile should be also exchanged according to periodic, aperiodic, event, request and response. Consequently, a lot of network traffic occur and computing power require. Solving theses problem, the profile exchange research needs. we analyze creation information, exchange information, and exchange form of the profile information in contents adaptation system for effective profile exchange and define exchange procedure of the profile using the analyzed profile information. we also propose providing method of the profile configured information for decreasing profile processing time and user setting method for decreasing the number of profile transmission. As a result of performance evaluation, providing method of the profile configured information reduce 7% processing time and user setting method decrease the number of profile transmission are effective to exchange the profile.
