  • The precision and reliability of the Computer Image Analysis technique using a desk top computer for extracting information from carcass cross section scans was evaluated by the repeatability (R) and coefficient of variation (CV) for error variance. The 6th and 7th ribs cross section of carcasses from 55 fattened Japanese Black steers were used. The image analysis was conducted using a desk top computer (Macintosh-Apple Vision 1710 Display) connected to a scanner and an image capture camera. Two software applications, Adobe Photoshop and Mac Scope were used interchangeably. The information extracted and measured were individual muscle area, circumference length, long and short axes lengths, muscle direction; distance between any two muscle centers of gravity; cross section total area, lean, fat, and bone. The information was extracted after the processes of scanning, digitization, masking, muscle separation, and binarization. When using the Computer Image Analysis technique by desk top computer, proper digitization and selection of scanning resolution are very important in order to obtain accurate information. The R-values for muscle area, circumference, long and axes lengths, and direction ranged from 0.95 to 0.99, whereas those of the distance between any two muscle centers of gravity ranged from 0.96 to 0.99, respectively. For the cross section total area, lean, fat, and bone it ranged from 0.83 to 0.99. Excellent repeatability measurements were observed for muscle direction and distance between any two muscle centers of gravity. The results indicate that the Computer Image Analysis technique using a desk top computer for extracting information from carcass cross section is reliable and has high precision.

  • With rapidly changing modem information technology, the structure of our lifestyle has underwent much changes in our society. One of these changes is an immense distribution of computer desks, which became necessities of life in various organizations, companies and public offices as well as at home. Therefore, many companies are faced with the necessity of bringing about a new product with esthetic needs and new functions and come to have opportunities to make profits from top-quality products based on competitive design development. The academic design support program in collaboration with industry can provide design-related industry with a design assistance for a new product development, in addition, it can give to the professional faculty of the college the chances to contribute to advancement of design industry of the nation. To accomplish the need and purpose of this research, the design development of unified computer desks was carried out with the introduction of life-long Universal design concept named ‘Design For All.’ The theoretical background of this study researched all the literature on the terms definition of a computer desk, the concept and definition of Universal design and design support program in collaboration with industry and performed data analyses for a product development through an analysis of domestic products and a benchmarking of foreign products. On the basis of these theoretical background and analysis results, this research brought out a new product through designing processes and the information of this production could be utilized via the feedback of a new product. That is, this research was done for a practical use.

  • Recently, electronic systems including computers have been rapidly shrinking in size while at the same time the complexity and the capability of these systems continue to grow/sup [1]/. Thus, system volumes have decreased as system power has increased, resulting in dramatic increases in system heat density. The high temperature of the computer system is considered as the major reason for low performance and shortening life of the product. It is necessary to solve this problem due to the heat density increased and to develop the design skill of the computer cabinet according to miniaturization. M4500 desk-top computer was selected for analyzing the thermal management inside cabinet. The cabinet volume, the configuration of the heating devices, the size and location of air ventilation, and the fan selection have been investigated as the important parameters to find out an optimal cabinet design. The objectives of this project were to analyze which design parameters would affect cooling performance by thermal strategy, to design an optimal model, and to measure the temperatures of the main parts to confirm the effect of the thermal design. The temperatures of each part of the optimal model were compared with those of the existing model. As a result. the volume of this miniaturized model was about 16% smaller than that of M4500 without any change in operating performance.

  • 기존의 가상화 시스템에서 사용되던 스케줄러는 기존 서버 환경을 기반으로 구현되었다. 즉, 기존 데스크톱 운영체계와는 달리 선점형 멀티테스킹 작업방식에 대한 고려가 부족하다. 때문에 본 논문에서는 데스크톱 환경에서 XEN 가상화 시스템을 사용할 경우 사용자 작업을 우선적으로 선점하는 Credit 스케줄러를 제시한다. Credit 스케줄러의 I/O 도메인 Boost 기능의 수정을 통해 데스크톱 사용자가 작업하는 가상 머신에 대한 성능을 향상시키는 Credit 스케줄러를 제안하였다. 또한 시뮬레이션을 통해 본 논문에서 제안한 스케줄러가 목적에 맞게 동작하는지 확인할 수 있었다.

  • With installation of the computerized data acquisition system on the towing carriage of KRIS towing tank, the testing techniques of resistance test, propeller open-water test, self-propulsion test and wake survey at propeller disk were remarkably improved and automated. For the self-propulsion test a new method was developed with aid of a digital desk-top computer. This method is based on extracting advantages both from British method and Continental method, that is, the accuracy from the constant speed method and the effciency from the constant load method. The KRIS method has been successfully practized with the improved accuracy, stability and efficiency. Details of the new method are described in this paper.

  • The treatment of chronic digital pain and cold intolerance due to Raynaud's phenomenon is quite difficult especially it is combined with scleroderma. Several surgical trial such as cervicothoracic sympathectomy have been attempted for the medically unresponsible Raynaud's phenomenon, but their results were unsatisfactory. We have tried peripheral periarterial sympathectomy for the 44 years old female patient who had medically unresponsible severe Raynaud's phenomenon with scleroderma. Periarterial adventitial stripping was performed at the level of wrist, superficial palmar arch, common digital artery and proper digital artery about 1.5-2 cm in length. Preoperative angiography and radioactive angiography were done and preoperatively and postoperatively the blood flow was measured by the desk top computer-aided histogram. Both hands digital pain were markedly reduced after operation and blood flow increased as compaired with the preoperative measure.
