This paper presents several case studies of asian colleges's co-op program for successful operation of KOREATECH IPP(Industry Professional Practice) program. The IPP program is a new educational model that combines academic study and industrial work through university-industry cooperation. The IPP experience will lead the university graduates to improve their employment competencies and will be a key to solve the problems of the labor mismatch between university and industry. We will discuss and analyze the strengths and the weaknesses of the Co-op programs of the Kyoto sangyo university, the Hong Kong polytechnic university and the suranaree university in thailand. Based on these case studies, we summarized several benchmarking points for the successful operation of IPP program.

This is a report of successful conversion arterial switch operation for failed Sunning procedure in transposition of the great arteries(TGA) with ventricular septal defect(VSD). A 15 month-male patient was admitted due to intractable congestive heart failure after Sunning operation was done at the age of 8 months. Angiography revealed marked dysfunction of the morphologic right ventricle with tricuspid regurgitation and residual VSD. The pulmonary ventricle 1 systemic ventricle pressure ratio' of 75/85 at catheter study enabled us to do the take down of denning repair, patch closure of VSD and arterial switch without pulmonary artery banding. After the operation, the baby showed good growth with normal ventricular function.

Communication Ocean Meteorological Satellite (COMS) has the hybrid mission of meteorological observation, ocean monitoring, and telecommunication service. The COMS is located at $128.2^{\circ}$ East longitude on the geostationary orbit and currently under normal operation service since April 2011. For the sake of the executions of the meteorological and the ocean mission as well as the satellite control and management, the satellite mission planning is daily performed. The satellite mission plans are sent to the satellite by the real-time operation and the satellite executes the missions as per the mission plans. In this paper the mission planning for COMS normal operation is discussed in terms of the ground station configuration and the characteristics of daily, weekly, monthly, and seasonal mission planning activities. The successful mission planning is also confirmed with the first one-year normal operation results.

This study introduces the new role of science museums. The practitioners from seven domestic science museums and four overseas ones participated in this study and responded the questionnaires. I identified what kind of science culture programs there are, if those programs were successful or not, and if unsuccessful, what kind of improvements can be made to be successful. The participating practitioners in science museums also developed an ideal and realistic community cooperation-based science culture programs and I explored the role of a new science museum for this purpose. In the case of current science culture programs, the most successful or not was the participation of visitors according to public relations, and the importance of public relations were mentioned as improvements. For a successful community cooperation-based science and culture program, active promotion, pre-operation team, dedicated personnel, open mind, and same purpose of other institutions, the will of both institutions, and economic support sponsors are important variables. In the case of the domestic science museums, the actual development and operation of the program showed that a successful community based program must have cooperation with other institutions in the same region, win-win connections, the dedicated human resources, and that each science museum's strengths were maximized. The science culture programs in the 21st century will enhance the innovative role of science museums making the use of local human and physical infrastructure, reflecting the needs of citizens, taking the initiative in the community, fostering cooperation-based professional human resources, and communicating smoothly with the government or local governments.

The meaning of innovative products pursued by pluralized societies is transforming. In the past, the markets were opened up after the products were released through various development strategies based on the needs of development. Recently, however, even the launching process of innovative products is differently operated and strategies with directions completely different from the past are used. In this regard, the paper aims to predict successful markets of innovative products in the future by analyzing the successful strategic cases of innovative products from both the past and the present. The following are the methodology and results of this study. - Conduct a case study and an analysis on which strategies were implemented after the release of successful innovative products in the past. - Conduct a case study and an analysis on the markets and launching trends of innovative products that were successful fairly recently. By reviewing the operation system of innovative products for each time period, it is assumed that startup companies releasing innovative products in the future will engage in the mass production of products through a pre-approval and post-production system, via overseas crowd funding. Moreover, we can expect that systems for partnerships between startups and conglomerates will be prepared in Korea within the near future. If we accurately perceive the operation trends related to the release of innovative products that come into existence by experiencing extreme changes, shortcuts to success will be available for startup companies preparing for such future.

In this paper, an operation algorithm for the fuel cell-battery hybrid power system is proposed. As the output current slope of the fuel cell is normally limited to protect the fuel cells' defection, efficient power distribution algorithm between the fuel cell and battery is very important for the successful hybrid control operation. For the experimentation, a 1kW dc-dc converter with 500W fuel cell stack and 1kWh Li-polymer battery is implemented.

This is a report of a case in which a left atrial myxoma was successfully removed by total cardiopulmonary bypass with total hemodilution and moderate hypothermia. The patient was a 17 old girl with mitral valvular symptoms that occured suddenly three months prior to operation. After the onset of symptoms. it was progressively aggravated to serious general condition. The preoperative diagnosis of left atrial tumor was made from echocardiography. and the tumor was confirmed as myxoma by the histopathological examination of the tumor tissue removed during operation. The myxoma was unusually originated from posterior wall of the left atrium. which was located between drainage orifices of right and left pulmonary veins, The tumor developed in the left atrial cavity and one of the polypoid processes of the myxoma was prolapsed into the the left ventricle through the mitral orifice. Following operation. there was no evidence for peripheral vascular embolism, and all valvular symptoms disappeared. The postoperative course was uneventful.
