This nationwide survey was conducted to evaluate the current status of the database system on gastric cancer patients in Korea. The Information Committee of Korean Gastric Cancer Association (KGCA) sent questionnaires about the database management to all 402 KGCA members in 110 institutes. In addition, we asked them to send the gastric cancer sheet and the pathologic report of gastric cancer used in their institutes. Response rates were $18.9\%$ (76/402) for individuals and $51.8\%$ (57/110) for institutes, respectively. Most of the university hospitals responded to the questionnaire (response rate of university hospital: $74.6\%$, 44/59). A regular conference of gastric cancer and a digitalization of the database on gastric cancer patients were performed in 29 ($50.9\%$) and 43 ($75.4\%$) out of 57 institutes, respectively. MS excel was most commonly used for the digitalization of the database, followed by MS access and SPSS. A regularly formed gastric cancer sheet and pathologic report were used in 38 ($66.7\%$) and 49 ($86.0\%$) institutes, respectively. Hospital computerization, such as an Order Communicating System, an Electric Medical Record, and a Picture Archiving/Communicating System had been set up previously or would be set up in the near future in most institutes. In 25 gastric cancer sheets collected, the mean number of total items was 72.9 ($15\∼177$). Identification datafor the patients, surgical data, and pathologic data were included on most of the sheets, but preoperative status, preoperative diagnostic data, and postoperative hospital course were not.

Numerous train operating companies provide training by means of driving simulators. A detailed analysis in the course of the rail research project 2TRAIN has shown that the simulation technology, the purposes of training and the overall concept of simulator-based training are rather diverse (Schmitz & Maag, 2008). A joint factor however are weak assessment capabilities and the fact that the simulator training is often not embedded into the overall competence management. This fact hinders an optimal use of the simulators. Therefore, 2TRAIN aims at the development of enhanced training and assessment tools. Taking into account that several simulators are already in use, the focus lays on the extension of existing simulation technology instead of developing entirely new systems. This extension comprises (1) a common data simulation interface (CDSI), (2) a rule-based expert system (ExSys), (3) a virtual instructor (VI), and (4) an _assessment database (AssDB). The foundation of this technical development is an assessment concept (PERMA concept) that is based on performance markers. The first part of the paper presents this assessment concept and a process model for the two major steps of driver performance assessment, i.e. (1) the specification of exercise and assessment and (2) the assessment algorithm and execution of the assessment. The second part describes the rationale and the functionalities of the simulator add-on tools. Finally, recommendations for further technical improvement and appropriate usage are given. based on the results of a pilot study.

Video-on-demand system in which users can request any video through the network at any time is made possible by rapid increase in network bandwidth and capacity of the media server. However true video-on-demand system cannot support all requests since bandwidth requirement is still too demanding. Therefore efficient bandwidth reduction algorithm is necessary. both the piggybacking method and the batching method are novel solutions that can provide more logical number of streams than the physical system can support. Of course each of them has its pros and cons. hence piggybacking with batching-by-size can take advantage of both the schemes. Some parameters such as the size of batch and the size of the catch-up window should be adjusted and order to maximize the bandwidth reduction for piggybacking with batching-by-size method. One of the most important parameters is decided optimally in this paper. Simulation shows that the optimized parameter can achieve considerable reductionand consequently remarkable enhancement in performance.

This paper analyzes and evaluates the importance of energy saving measures based on qualitative survey. Through literature review and group interviews with specialists, 4 factors, 13 measures for energy savings, and 4 evaluation criteria were selected to carry out an Analytic Hierarchy Process (AHP) analysis. At the first stage of AHP analysis, the importance of factors was derived, and then the importance of 13 measures. Lastly, the cross examination of 4 factors was carried out in order to evaluate the best possible qualitative considerations. The result revealed that 'choosing the best course weather', is the most important factor with the highest value on applicability and operational complexity criteria. These results may imply that operational considerations are regarded as a main factor to be taken into account when considering appropriate energy saving measures.

This study aims to analyze operation status of the professional fire investigation education in Korea and derive improvement measures. Study results showed that professional fire investigation educations are conducted mainly by public sectors (Fire Service, Police, Korea Electrical Safety Corp, Korea Gas Safety Corp, etc.) and the educations conducted by National Fire Service Academy are most systematic. In addition, there was no professional fire investigation educations conducted for private sector (fire accident suffers, common peoples, etc.) In order to improve the problems, this study suggests changing the National Fire Service Academy to lifelong education system in coordinance with the scholar's courses of universities, classifying the fire inspector qualification course (executed by National Emergency Management Agency) in five stages, and opening the fire inspector qualification test to the public.

A sub-structure is uplift if the floating greater than dead load of a structure. When such occasion arise, a structure sustain damage. In general, the measures for floating prevention of structure are a permanent anchor method and a drainage method. The primary construction cost of a permanent anchor method is heavy. And a drainage method is needed maintenance management long term. At this point, the measures for floating prevention of a notion being requires the other days. Therefore, at this study a simple construction and a economic vertical drainage system was developed. The findings be used in the in-situ and gave careful consideration to an application. The result of examination, this system considering a characteristic of coefficient of permeability for the ground controls occurrence of floating despite the water level rise of the ground, which a period of construction get shorter compared with other methods, which understood that measures satisfactory in the financial aspect. Especially, A structure occurring effects of flatting under the course of construction made use of it. As the result of the effect of it was confirmed by construction.
