In this paper, we describe our vision of a "Just-in-time" initiative to solve the Data Interoperability Problem (a.k.a. INTEROP.) We provide an architectural overview of our initiative which draws upon existing technologies to develop an immersive and collaborative approach which aims at empowering data stakeholders (e.g., data producers and data consumers) with integrated tools to interact and collaborate with each other while directly manipulating visual representations of their data in an immersive environment (e.g., implemented via Second Life.) The semantics of these visual representations and the operations associated with the data are supported by ontologies defined using the Common Logic Framework (CL). Data operations gestured by the stakeholders, through their avatars, are translated to a variety of generated resources such as multi-language source code, visualizations, web pages, and web services. The generality of the approach is supported by a plug-in architecture which allows expert users to customize tasks such as data admission, data manipulation in the immersive world, and automatic generation of resources. This approach is designed with a mindset aimed at enabling stakeholders from diverse domains to exchange data and generate new knowledge.

The work-man's Uniform should be coincident with the image of his firm and accounted of the function according s its purpose. We made questions to 404 workers at 8firm in our country through the questionnaire papers to know about a work-man's uniform and researched whether the satisfactory in wearing his uniform had relation with his type of business, grade, carrier, age, marriage, and monthly income. The results of this study is as follows; 1. In the case of wearing the uniform many workers answered they always wore their uniform in the firm. It was shown that the office workers wore their uniform much more than workers in the production department. The longer the time working, the older age, the lower grade of school career are, he more workers wear. the order of the importance for he uniform was the function, the symbol, the originality, and the fashion. The longer their career in the firm was, the more important the function of their uniform was. 2. The order of dirty pat in taking care of the uniform was cuffs, color, the front of part in an upper garment and below the knee, the hip in pants It was very easy for the workers in the experts, or administrators and office workers than others to be dirty in the cuffs part of the uniform. Worn part of the uniform showed highest cuffs in an upper garment and a zipper in pants. The order of cleaning the uniform was washing by water, no ironing, and cleaning in their house.

A male baby with intrauterine growth retardation had a short neck, small hands and feet, hypospadia, both grade I hydronephrosis, type II atrial septal defect, and moderate valvular pulmonary stenosis. The routine chromosome and banding analyses revealed a 46,XY,rec(8)del(8)(p21)dup(8) (q24.1)inv(8)(p21q24.1)pat chromosome constitution. His mother has normal chromosomes, but the father had 46,XY,inv(8)(p21q24.n Also his uncle had an inv(8) chromosome constitution. We used lymphocytes and examined 40 mitotic cells. All mitotic cells showed deletion of 8p21-->pter and duplication of 8q24.1 -->qter. Because Sp21 involves secretion of macrophage and lymphocyte against cancer cells, long-term follow-up for cancer will be needed.

NSSS Control Systems automatically mitigate transient conditions and leads to a stable plant condition without operator actions when a transient occurs during normal power operation. In this paper, the function and performance of NSSS control systems were examined and evaluated by comparing the predicted results with the measured data for the selected events. Loss of a Main Feedwater Pump and Load Rejection to House Load Operation events were selected for the evaluation among the transient tests peformed during the Power Ascension Test (PAT) of UCN unit 4. The overall schematic control actions of NSSS control systems can be evaluated easily through the observation of these two typical events. The selected events were analyzed by the KISPAC computer code[l] which had been used in developing the control logic and determining the control setpoints during the plant design. Additionally, the performance of FWCS during low power operation was evaluated. The result of evaluation showed that the NSSS control systems were designed properly and the performance of the NSSS control systems was excellent and also the computer code had a good prediction capability.

This research was attempted to seek for a positive approach within the framework of physical therapy instead of the drug treatment in the past, with regard to the ischemic brain injury in the early stage. Accordingly, the aim of this research is to observe the change of HSP27 and HSP70, the genes that are expressed in the early stage of brain injury and to investigate the effects of needle electrode electrical stimulation(NEES), upon applying NEES after ischemia. The experimental method is to give rise to global ischemia and apply NEES to 27 SD-Pat rats with the particulars of being eight-week-old, male, around 300g, and adapted to laboratory environment for more than a week, and divide them into three groups, that is, GV20 NEES group(n=9), L14 NEES group(n=9), no applied NEES global ischemia(GI) group(n=9), and then observe their changes of HSP27 and HSP70 at the time lapse of 6, 9 hr and 12 hr after ischemia, using immunohistochemistry methods. Upon observing through the immunohistochemistry method, it was noticed that there was a significant difference between the GV20 NEES group and the L14 NEES group as for HSP27 and there were significant differences among all groups as for HSP70(p<.05). Accordingly, it is supposed that the application of NEES after the outbreak of cerebral ischemia delay the apoptosis in the early ischemic part of forebrain or protect neurons against apoptosis.

In the present study, it was found that the susceptible variety Khao-tah-haeng 17, at all four predisposing temperature regimes, produced more typical lesions than hypersensitive lesions when inoculated with most of the blast fungus isolates. Tetep, Carreon, IR36 and Sensho produced more hypersensitive lesions than typical lesions at all four predisposing temperature regimes. Highly significant differences among predisposing temperature regimes and rice varieties for number of hypersensitive lesions and number of typical lesions were found. Symptom occurrence on a specific variety, as measured by the number of typical lesions, was more affected by predisposition temperature or blast isolate than by temperature and isolate combined. Symptom occurrence on a specific variety, as measured by the number of hypersensitive lesions, was more affected by blast isolate than by predisposition temperature.

Delay, delay variation and packet loss rate are principal QoS(Quality of Service) elements of packet communication. This paper proposes a new buffer allocation mechanism to improve the packet loss performance in such a situation that multiple logical buffers share a single physical memory buffer. In the proposed buffer allocation mechanism, the movement of dynamic threshold follows a curved track instead of a straight line which is used in the DT(dynamic threshold) mechanism. In order evaluate the effectiveness of the proposed mechanism, it is compared with the existing previously proposed mechanisms in several aspects including NC(no control), ST(Static Threshold) and DT mechanisms.

YGN 3 and 4 are the nuclear power plants having System 80 characteristics with a rated thermal output of 2815 MWth and a nominal net electrical output of 1040 MWe. YGN 3 achieved commercial operation on March 31, 1995 and YGN 4 completed Power Ascension Test (PAT) at 20%, 50%, 80% and 100% power by September 23, 1995. YGN 3 and 4 design incorporates the Reactor Power Cutback System (RPCS) which reduces plant trips caused by Loss of Load (LOL)/Turbine Trip and Loss of One Main Feedwater Pump (LOMFWP). The key design objective of the RPCS is to improve overall plant availability and performance, while minimizing challenges to the plant safety systems. The RPCS is designed to rapidly reduce reactor power by dropping preselected Control Element Assemblies (CEAs) while other NSSS control systems maintain process parameters within acceptable ranges. Extensive RPCS related tests performed during the initial startup of YGN 4 demonstrated that the RPCS can maintain the reactor on-line without opening primary or secondary safety valves and without actuating the Engineered Safety Features Actuation System (ESFAS). It is expected that use of the RPCS at YGN will increase the overall availability of the units and reduce the number of challenges to plant safety systems.
