Recently the countries breeding bears such as China and Vietnam are promoting a policy that gives relief to wild animals through agreement with AAF and WSPA. Currently our country has lacking breeding space for the increased number of bred bears due to the prohibition of bear import and export from joining the CITES in 1992. There needs to be a place that treats, protects accepts breed bears in the terms of animal welfare. The bear park was hoped to be designed as a means to give relief to bears and promote harmony with the local society, and is made of parking area, waiting area, visitors center, treatment research management facilities, restaurants, food warehouse, food store, bear museum, sanitation facilities, gondola, plaza, rehabilitation area for wild animals, outdoor exhibition center, direct indirect experience area of wild animals, resting facilities and areas, photo zones, bear playground, bear experiencing facilities, fences, information facilities, tree protection facilities and more. The design can be used as a reference in examining alternative measures following the future change in breeding policy as a bear park example which reflected the ecology of a bear in the term of animal welfare.

Having observed the restriction of the current Web technology, the semantic Web has been developed, and it now has grown up with the core help of the W3C to a level where it recommends the OWL Web ontology language. Besides, in order to deduce the information out of OWL data, several inference systems have been developed such as Jena, Jess, and JTP. Unfortunately, however, quite few systems can effectively handle recently developed OWL data, and further, due to the limitation of file-based operation, the current inference systems cannot meet the requirements for handing huge OWL data. An efficient method for storing and searching ontology data is essential for ensuring stable information inference processes. In this study, firstly, we proposed a model based on the database management system to transform and store OWL data and to enable deduction process from the database. Secondly, we designed and implemented an effective OWL storing system based on our model. Finally, we compare our system with the previous inference systems through experimental performance analysis.

After large-scale flooding damage occurred along the Imjin river in 1996, 1998, and 1999, the Hantan river flood control dam was planned, and it has since been under construction. Unlike existing dams in Korea, the Hantan river flood control dam will remain fully open except during high floods, when the dam will store flood water temporarily to reduce flood peaks and flood water volume downstream. During past flooding seasons, floating debris has caused difficulties in the management of large-scale dams. Most of the existing multipurpose dams in Korea have installed nets to collect floating debris based on many years of experience with and data about inflow and distribution of floating debris in the dams. For the Hantan river flood control dam, however, collection of data about inflow and distribution of floating debris is not possible as the dam is located near the border area between North and South Korea. In order to devise a preliminary plan to collect floating debris in the Hantan river flood control dam, an EFDC hydrodynamic model was used to analyze the behavior of floating debris during high floods. The Lagrangian particle tracking method was utilized to simulate the behavior of floating debris in the dam. Based on the analysis of paths and final destinations of the particles, seven collection points were selected where it seemed to be effective to collect floating debris, as debris is likely to accumulate there in high density.

This study was to propose a basic model of specialization in home economics for vocational high school development in JellaNamdo. The results were summarized as follows. First. based on the changes in economic environment into service industry and national educational policy and local vocational educational Policy, it may be good time to socially discuss special vocational high school in home economics in JellaNamdo in the light of meeting local students' demand. Secondly, considering local students' preference and the conditions of local economy and industry. Thirdly, the system for specialization in home economics of vacational high school may be suggested. The basic model was organized plans of system reformation by stages, a substantial plans, and academic or employment course development. System reformation plans was that the high school-concentrated district should be first selected by area and department and one high school should be selected as special high school in home economics. Then specific method should proceed school name, the measure to recruit students, specific method for reorganizing department. and curriculum. Finally, the annual plan to establish new department and to recruit students should be Prepared. Substantial plans were to actually forward such methods to reorganize system and to enhance the qualify of vocational high school education. the method for making substantial should be studied further It may include: the methods to ensure special teachers, training room, and facilities. the prospect and direction of career development, employment, or initiation, special research, and the application to educational environment. Employment courses were developed SOHO establishment in small capital and special store management. And academic courses was to enter a collage or university in conjunction with major departments.

Association Rule Mining has been successfully used for mining knowledge in static environment but it provides limited features to discovery time-dependent knowledge from multi-point data set. The aim of this paper is to develop a methodology which detects changes of customer behavior automatically from customer profiles and sales data at different multi-point snapshots. This paper proposes a procedure named 'Recursive Change Mining' for detecting continuous change of customer purchase behavior. The Recursive Change Mining Procedure is basically extended association rule mining and it assures to discover continuous and repetitive changes from data sets which collected at multi-periods. A case study on L department store is also provided.

Purpose Consumption behaviors of consumers have changed with the widespread use of the Internet and smart phones, and accordingly online marketing activities are becoming ever more prevalent. Yet, the domestic food-service industry has yet to offer an Omni-Channel order system that encompasses a online, offline, and mobile interface. Also, a multilingual menu ordering service for foreign tourists is not yet available. Therefore, if an order service system accessible online and offline which could provide multi-language services were implemented, the satisfaction of the service provider and domestic and foreign customers would be maximized. Design/methodology/approach By designing an electronic menu based on open an OS and providing electronic menus in offline stores, we have completed the design of a linked order system which would be available everywhere (online, offline, and mobile). The CMS was developed to integrate these three mediums and the entire operator was designed to receive basic information and statistical information about the merchants, or store operators. Also, a multilingual term dictionary containing menu information for foreign tourists was made into a database so that foreign tourists who are having difficulty in communication can use it more easily. Findings We have made it possible for customers to use the order service without distinction between online, offline, and mobile platforms, and have proved that it is a more efficient and convenient service for customers as well as operators. Nevertheless, as an initial model, the implemented system has limitations on the execution of the payment support method in the electronic menu board and in the management division of the CMS. In case of commercialization, it is necessary to make an alliance of efforts to attract initial franchises. Through further supplementation, we expect the online and offline connection-types martservice system will maximize the satisfaction of both operators and customers alike.

In this paper, we designed the authentication system for home network service and applied it to actual sensor nodes. The pair-wise pre-distribution key skim is applied for prevention of authentication key from sniffing on the wireless sensor networks. The authentication key and data are encrypted by using the CBC mode RC5 algorithm based on the SPINS. The experimental environment consists of a base station (BS)and sensor nodes and each sensor node sends both sensing data and the encrypted authentication key to the BS. For simulations we set up some what-if scenarios of security menaces in home network service.Slightly modified the TOS_Msg data arrays of TinyOS is suggested to store 8-byte authentication key which can enable data encryption and authentication at the each sensor node. As a result, malfunction caused by communication between BS and nodes of other groups of added nodes having malicious purpose can be protected. Also, we confirmed that a critical data of home networking service like vital signal can be transmitted securely through this system by encryption technique.

This research is an empirical research that surveys the influence factors of franchisee's compliance and precedence, which have a direct effect on the success of franchisor, from the view of relation exchange theory. The results herein show that the trust of franchisees towards franchisor has a complete mediating effect between conflict and compliance. This means that in a franchise system, it is important to build trust in order to successfully manage franchisees. Trust built between franchisor and the franchisee has a dominating effect based on relationship even on domains not specified on the contract. Also, it is very important in that it decreases frequently occurring conflicts caused by disagreement of interests and unfair relationship of power, and effectuates compliance of franchisees. Such result is a meaningful theoretical and practical contribution in that it has for the first time domestically investigated the mechanism of relationship leading from conflict and trust to compliance of franchisees by methods of theoretical discussion and empirical analysis.

Since XML is emerging as the de facto standard for exchanging and representation of data on the web, the amount of XML data has rapidly increased. Thus, the need for effective store and retrieval of U data has arisen. Since the existing techniques such as XRel which is an XML storage and management technique using RDBMS simply record the existing all label paths, diverse classes of label path expressions could not be efficiently supported. In this paper, we present a technique which supports storage and retrieval for XML data using RDBMS efficiently compared with the existing approaches. Since the proposed technique keeps the XML path index on the relational database and replace label paths with path identifiers, diverse XML queries can be evaluated compared with existing approaches. Also, the proposed technique does not require the modification of the relational database engine and consumes the disk space less. Our experimental result demonstrates the better query performance compared with existing techniques.
