Recent research has been actively carried out on systems that want to optimize resource utilization by analyzing the intended behavior and pattern of behavior of objects (users, consumers). A service system that applies information about an object's location or behavior must include a location trigger processing system for tracking an object's real-time location. In this paper, we analyze design problems for the implementation of a context-awareness based location trigger system, and present system models based on analysis details. For this purpose, this paper introduces the concept of location trigger for intelligent location tracking techniques about moving situations of objects, and suggests a mobile agent system with active rules that can perform monitoring and appropriate actions based on sensing information and location context information, and uses them to design and implement the location trigger system for context-awareness based location services. The proposed system is verified by implementing location trigger processing scenarios and trigger service and action service protocols. In addition, through experiments on mobile agents with active rules, it is suggested that the proposed system can optimize the role and function of the application system by using rules appropriate to the service characteristics and that it is scalable and effective for location-based service systems. This paper is a preliminary study for the establishment of an optimization system for utilizing resources (equipment, power, manpower, etc.) through the active characteristics of systems such as real-time remote autonomous control and exception handling over consumption patterns and behavior changes of power users. The proposed system can be used in system configurations that induce optimization of resource utilization through intelligent warning and action based on location of objects, and can be effectively applied to the development of various location service systems.

INCOTERMS 2010 apply to the International Trade Contract for the last 5 years. The export trade condition and the document type for last 10 years was researched to analysis of the practical problems of INCOTERMS 2010 application. The result of the research; First, several rules which are against the official INCOTERMS 2010 rules are used. Second, the conventional rules like FAS FOB, CIF and CFR which are used for the ocean and inland transportation are applied without any changes. Third, the issue of the time of delivery(transfer of ownership) at the CPT and CIP affects not to activate these two rules. Fourth, the frequency of the DAT use is low. Because, the terminal designate is hard at the point of the contract and the terminal is changeable during the transport. According to these issues, the active publicity campaign is needed for the INCOTERMS 2010. And, the analysis of the terms and the solution of conflict are also needed.

After more than 15 years of negotiations, China was finally able to achieve the WTO membership, opening up new trade opportunities for China as well as existing WTO members. China accepted a special safeguard mechanism as one of its WTO- plus commitments. And in response, Korea has since introduced China special safeguard rules, which in simple terms, allows an invocation of safeguard measures against Chinese product imports under more lapse conditions than would normally be allowed under the existing general safeguard rules. China also introduced new safeguard rules in November 2001 in an effort to increase transparency in its operation of safeguard measures. However, the current article contends that the new rules pose a serious threat to free trade in the form of the retaliation provision, which enables China to take unilateral retaliatory actions against safeguard measures on Chinese product imports, It indicates that the provision could be operated in an arbitrary manner as the US Super 301, and lead to infringements of WTO disciplines. This paper indicates that the foregoing elements could lead to mort trade disputes between Korea China regarding safeguard measures and subsequent retaliations on the hills of the so called the Garlic War. The current article goes on to offer policy recommendations toward deterring such disputes. First, it recommends a more active invocation of Korea's own retaliatory provision against China's unilateral actions at least to gain negotiating leverage. Second, it sites problems involving China's still conspicuous state-trading practices, and proposes to raise issues again China to induce more faithful implementation of WTO disciplines Final, it stresses the importance of preventing disputes before they arise, and suggests several specific preventive measures.

An active control for the swing of crane systems is very important for increasing the productivity. This article introduces the control for the position and the swing of a crane using the fuzzy learning method. Because the crane is a multi-variable system, learning is done to control both position and swing of the crane. Also the fuzzy control rules are separately acquired with the loading and unloading situation of the crane for more accurate control. The result of simulations shows that the crane is just controlled for a very large swing angle of 1 radian within nearly one cycle.

지금까지의 지리정보시스템에서는 시스템 구축관점에서의 공간 객체의 모델링, 공간 객체의 효율적인 저장방법, 인덱싱 방법 등이 중요한 연구 과제였으나 지리정보 시스템 관련 기술의 발달과 활용분야가 다양해짐에 따라 공간 데이터의 정확성에 대한 연구가 더욱더 중요시되고 있다. 본 논문에서는 지리 정보 시스템에서 위상 객체들간에 만족해야 하는 위상적 무결성 제약조건의 정의 과정을 보이고, 이러한 위상적 무결성 제약조건을 관리하기 위한 시스템을 설계한다.

In this paper, a control algorithm suitable for multi-objective control problems is proposed based on the orthogonal array which is normally used in statistics and industrial engineering. And a newly defined Nth-certainty factor is suggested, which can effectively exclude the less confident rules. The Nth-certainty factor is defined by the F-values of the ANOVA(analysis of variance) table. It is shown that the algorithm can be successfully adopted to the design of controller for an active magnetic bearing system.

In order to create and utilize experiential equipment that can be effectively used in school safety education, this paper uses the Korean Safety Education Association's CPR simulator to utilize the elements of educational games: goals, rules, competition, challenge, fantasy, safety, and fun. When the content that combines game elements with general educational equipment was utilized in school education sites, significant results were obtained on the effectiveness of education with active participation of students.

A new fuzzy control algorithm for the control of active magnetic bearing (AMB) systems is proposed in this paper. It combines PDC design of Joh et al. [8][9] and Namdani-gype control rules using fuzzy singletons to handle the nonlinear characteristics of AMB systems efficiently. They are named fine mode control and rough mode control , respectively. The rough mode control yields the fastest response for large deviation of the rotor and the fine mode control fives desired transient response for small deviation of the rotor. The proposed algorithm is applied a AMB systems to verify the performance of the method, The comparison of the proposed method to a linear controller using a linearized model about the equilibrium point and PDC algorithm in [7] show the superiority of the proposed algorithm.
