The aim of this article is to study the new searching tool for era of multimedia. Thesaurus is a useful tool but is constituted with noun phrase including the adjective for retrieving the human Sensibility. Therefore, I experimentally construct the Sensibility thesaurus using the color scale which contains the Sensibility meanings. Terms are 261, Relation standards are distance and ratio of reiteration between the terms. I would use an exclusive program of the thesaurus construction for Sensibility adjective.

This study was carried out to investigate the status and development direction of horse riding industry for rural development of Korea. Library research and field survey were conducted to collect relevant data such as number of horse and size of horse farms, facilities for horse riding and educational institutions for youths and farmers and the results obtained were as follows : Only a few institutions among high schools, colleges and universities were observed to deliver horse riding programs. For farmers, no equestrian specialist was available in agricultural extension offices. Horse meat is consumed mostly in Jeju Island in Korea. Relevant institutions should be also strengthened including formal and nonformal education for horse riding and much more schools and universities should adopt horse riding program for the training of youths and farmers. Considering the obesity problem, the nutritional composition of horse meat is better than those of pork or beef, so promotion of horse meat consumption also should be strengthened.

The complexity of newly developed protection algorithm and higher performance requested by the user makes the software embedded in the protective relay much harder to develop and maintain. The versatility of 32bit microprocessor and the availability of cheaper memory semiconductors introduced the fertile developing background for the protective relay developers. The use of component object model(COM) in the software developing process enables the developer to write much complex code in the easy and safe way and to maintain the code easily, too. And the aid of the COM library, the distributed computing environment will be expected to appear by the use of the COM programming model in the protective relay firmware program.

Electric arc furnaces (EAFs) are a main cause of voltage flicker due to the interaction of the high demand currents of the load with the supply system impedance. The stochastic models have described the physical phenomena of EAFs. An alternative approach is to include deterministic chaos in the characterization of the arc currents. In this paper, a chaotic approach to such modeling is described and justified. At the same time, a DLL (Dynamic Link Library) module, which is a FORTRAN interface with TACS (Transient Analysis of Control Systems), is developed to implement the chaotic load model in the Electromagnetic Transients Program (EMTP). The details of the module and the results of tests performed on the module to verify the model and to illustrate its capabilities are presented in this paper.

The paper proposes an implementation architecture of DiffServ-over-MPLS traffic engineering (TE) on Intel IXP2400 network processor using Intel IXA SDK 4.0 Framework. Program architecture and functions are described. Also fast and scalable range-match classification scheme is proposed for DiffServ-over-MPLS TE that has been integrated with functional blocks from Intel Microblocks library. Performance test shows that application can process packets at approximate data rate of 3.5 Gbps. The proposed implementation architecture of DiffServ-over-MPLS TE on Network processor can provide guaranteed QoS on high-speed next generation Internet, while being flexible and easily modifiable.

Studies on daylighting of buildings have been continuously increased due to the recent escalating oil price and low-carbon strategies in developed countries. Daylighting of buildings not only saves electric energy, but provide the occupants with a comfort visual environment. Atrium spaces are adopted by many modern buildings to improve daylight performance of deep interior spaces. Among the various types of atria, the four-sided type atrium is frequently adopted by library buildings, governmental buildings and office buildings. This study aims to suggest daylighting design data for adjacent occupied spaces by conducting dynamic simulations using Daysim program. Daylight Factor(DF), Daylight Autonomy(DA) and Useful Daylight Illuminance(UDI) levels for 12 measurement points in adjacent occupied spaces were calculated for square-shape four-sided atria with different SAR(Section Aspect Ratio) and different canopy transmittance.

Electric arc furnaces (EAFs) use bulk electrical energy to create heat in metal refining industries. The electric arc process is a main cause of the degradation of the electric power quality such as voltage flicker due to the interaction of the high demand currents of the load with the supply system impedance. The stochastic models have described the aperiodic physical phenomena of EAFs. An alternative approach is to include deterministic chaos in the characterization of the arc currents. In this parer, a chaotic approach to such modeling is described and justified. At the same time, a DLL(Dynamic Link Library) module, which is a FORTRAN interface with TACS (Transient Analysis of Control Systems), is developed to implement the chaotic load model in the Electromagnetic Transients Program (EMTP). The details of the module and the results of tests performed on the module to verify the model and to illustrate its capabilities are presented in this paper.

ASC(Avionics System Computer) was developed to control weapon delivery and navigation sensors, and to perform man-machine interface with pilots for XKO-1 aircraft. The data communications between ASC and UFC(Up Front Controller), DC(Data Concentrator) were implemented by RS422 serial data bus. Also, SCIL(Standard Computer Interface Library) was designed to facilitate control and management of the computer hardware resources and is embedded in the ASC. These structures have a merit of noise immunity and a reduction of wire harness for signal lines, and enable OFP(Operational Flight Program) programmers to use the SCIL easily without knowing hardware details. Manufactured system was on installed on XKO-1, and peformed for BIT(Built In Test) and interface test with UFC and DC. The test results show that it meets the system requirements.
