A fuzzy query language, called FSQL, in the relational databases is introduced in this paper. In general, database systems have query systems which are able to retrieve and manipulate precise data. However, such queries are hard to operate on the real world applications since their queries are often imprecise or incomplete. Recently, considerable attention has been given to research dealing with vagueness of the query in relational database systems. In this paper we have suggested an effective method of accepting vagueness of the query in data processing. The syntax of FSQL is formally defined with EBNF, and an interpreter of FSQL has been implemented as a prototype.

Objectives : This study aims to report current trend of Mibyeong health policy and service in China from interview of China Technology Research Group. Methods : China Technology Research Group visited Guanganmen hospital, Yanhuang Dongfang Company, Xinjingzhen health center, and Shanghai Shuguang hospital. With an interpreter, We had interviews about Mibyeong health service and policy trend, medical instrument, and research issue. Results :Mibyeong health service was performed based on KY3H system and collaboration with traditional Chinese medicine hospital. Mibyeong health service consists of diagnosis with nine constitutional type, health guide and preventive treatment. Community health center also provide Mibyeong health service, with cooperative treatment of traditional Chinese medicine and western medicine. China's Mibyeong health policy is established by Top-down decision, even though there is not enough evidence for providing health service to consumer. Through constitutional diagnosis, examinations, and treatment, huge data have been stacked; however, assessment and research based on these data are not processed well. Cooperative treatment of traditional Chinese medicine and western medicine is widely provided to patients, and their works are relatively well classified. Conclusions : China plays leading role in Mibyeong service and it seems to be developed more than Korea's. Further study is necessary to establish Mibyeong policy and health service in Korea.

Dual-gate PCRAM which unify capacitor-less DRAM and NVM using a PCM instead of a typical SONOS flash memory is proposed as 1 transistor. $VO_2$ changes its phase between insulator and metal states by temperature and field. The front-gate and back-gate control NVM and DRAM, respectively. The feasibility of URAM is investigated through simulation using c-interpreter and finite element analysis. Threshold voltage of NVM is 0.5 V that is based on measured results from previous fabricated 1TPCM with $VO_2$. Current sensing margin of DRAM is 3 ${\mu}A$. PCM does not interfere with DRAM in the memory characteristics unlike SONOS NVM. This novel unified dual-gate PCRAM reported in this work has 1 transistor, a low RESET/SET voltage, a fast write/erase time and a small cell so that it could be suitable for future production of URAM.

This paper introduces the basic concepts and requirements of database system based on the object-oriented paradigm,and presents the overview of the design of an object-oriented data base system which refects those conceprs and requirements . The system imolemented on C++,consists of three structure layers.The inner layer, which is in fact a storage system,performs file I/O,while the inermediate layer is responisible for most of the functions except the ones rerated to the user interface, such as the transaction management,the schema manage-ment,and the management of buffers in main memory etc.The outer layer,designed mainly for the uwerunteface,mot only privides the functions for graphical user interface,preprocessor,and interpreter etc,but also supports extended SQL for object-oriented features.

We discuss development of a simulator for automated manufacturing systems (AMSs) which have sophisticated automated material handling equipments and complicated work flows. The simulator is designed to satisfy the following requirements. A user should be able to easily configure or specify an AMS through a graphical user interface (GUI) and minimal data input. The user should be able to model diverse and complied control logic for automated material handling systems like automated guided vehicle (AGV) systems, robot workcell systems and conveyor systems as well as complicated job flow program. Real time animation is desired. Finally, the simulator should be easily maintained and extended. To satisfy the requirements, we use an object-oriented paradigm for modeling, designing, and programming of the simulator. We use an object-oriented modeling framework to design the modeling elements library, and take the process interaction approach for scheduling processes and events. To model a user-defined diverse control logic, we also develop a script language and its interpreter. We explain design and implementation strategies. We implement the simulator using Visual C++ 4.2 and Open GL on Windows NT and the Windows95. Some modeling examples will be demonstrated.

Globally, medical tourism draws attention as a national growth engine industry, and is actively expanding. Current medical tourism leans towards large hospitals making it difficult to attract new users. Users collect the information for medical tourism through various paths in order to receive medical consultations and customized tour services. To expand medical tourism to small and medium sized hospitals, it is necessary to have customized medical consultations, tours and interpreter services, which are the key elements of medical tourism. This paper suggests services that users can use to match medical consultations and find tours and interpreters they want at the same time. This paper suggests ways to provide integrated services based on the information experienced by users, combining the required items from the perspectives of each user, hospital and guide. To match the content provided by hospitals and guides with experience information from users systematically, this study suggests the convergence plan for a service model that can match the experience information between users and hospitals, between users and guides and between hospitals and guides systematically by operating the data in the universal container.

The previous research has been mainly focused on individual technology of voice recognition, voice synthesis, translation, and bone transmission technical. Recently, commercial models have been produced using aforementioned technologies. In this research, a new automated translation support system concept has been proposed by combining established technology of bone transmission and wireless system. The proposed system has following three major components. First, the hybrid system consist of headset, bone transmission and other technologies will recognize user's voice. Second, computer recognized voice (using small server attached to the user) of the user will be converted into digital signal. Then it will be translated into other user's language by translation algorithm. Third, the translated language will be wirelessly transmitted to the other party. The transmitted signal will be converted into voice in the other party's computer using the hybrid system. This hybrid system will transmit the clear message regardless of the noise level in the environment or user's hearing ability. By using the network technology, communication between users can also be clearly transmitted despite the distance.

Pyomindaehwa is a study book written in Korean and it takes a form of an investigation document made up of a conversation between Chosen's castaways and an interpreter taking place in Naesirogawa and Satsuma on the south end of Kyushu, Japan in the 19th century. This book is in three volumes. Many terminologies such as timber parts, sail, rigging and equipment have been shown in the last volume, which is mainly about a repairing process of drifting ship. Especially, timber parts' terminologies including hull's term were schematized in Kumamoto Text(1854b). This study have attempted to find out Naval architectural clues helping estimate actual drifting ship's type and bulk on the evidence of the contents. Based on the studies, it is possible to presume the type of Korean boats and ships, which are similar with the ones from database of 21 traditional fishing boats in the report on Investigation of Korean fishing boats studied previously. This paper has shown the logical process of presumption of types of boats.

In this paper we propose a method to analyze user's motion as a game command, and implement a sports serious game applied the motion analysis method as a command interpreter. Recently, various contents platforms appear in industrial market, the computer game contents plays an important role in these emerging platforms as a killer contents. The computer game has enough values as an independent major cultural product, moreover it has the potential to be applied in various other fields such as education, healthcare, training, and so on. It could motivate users to do something continuously, and it could also support an immersive environment in a certain special game contents such as VR game. The Serious game 'ChoDeungGangHo', implemented in this paper, is the sensory healthcare serious game based on 3D run game and fitness game. It is designed for user to train the various exercise element by just playing the game, and it also supports the user management system and the linkage of social media. We proposes the sensory serious game 'ChoDeungGangHo' as a model of commercial serious game.
