Background: The benefits of epicardial ultrasound scanning (EUS) in coronary artery bypass grafting (CABG) have not yet been established. The aim of this study was to evaluate the usefulness of EUS in CABG, including in the assessment of the quality of distal anastomoses, the identification of epicardial target vessels, and the evaluation of any graft issues other than the distal anastomoses. Methods: Fifty-three patients undergoing CABG were enrolled between March 2018 and February 2019. Intraoperative EUS was performed along with transit-time flow measurement (TTFM). Graft evaluations were performed early (shortly after surgery) and 1 year after surgery for 53 (100%) and 47 (88.7%) patients, respectively. Results: EUS was applied to assess the quality of all distal anastomoses, 32 target vessels, and 2 conduit trunks. Insufficient TTFM findings were obtained for 18 grafts. However, graft revision was performed for only 3 distal anastomoses; based on the EUS findings, the remaining 15 sites were not revised. The early and 1-year overall graft patency rates were 100% (141 anastomoses) and 96.1% (122 of 127 anastomoses), respectively. All 15 of the distal anastomoses that were not revised despite insufficient TTFM results were patent at the 1-year mark. Conclusion: The routine application of EUS in CABG could be beneficial by confirming the quality of surgery and reducing unnecessary procedures.

For a long time, most of advanced countries have supported the innovative firms with various support methods such as tax credit, subsidy, human resource education, and so on. Tax credit for innovation is the most popular industrial policy in these countries including Korea. However, in Korea, the effect of tax credit policy has been rarely analyzed. On the other hand, a considerable number of studies discover that tax credit policy in other countries influences positively on invest of R&D expenditure. This paper shows that tax credit policy positively influences on firm's innovation performances in Korea. The evaluated innovative effect of tax credit policy in this paper is more persuasive because it introduces various innovation performance variables including patent application with Propensity score matching method(PSM).

Nowadays, we make an attempt for media conversion from old to new media, carrying out to information society. These changes to new media are considered as new threat to printing media. New means such as CAD(Computer Aided Publishing), on-line novel and webzine can be regarded as new media and we are confronted with need of new changes in the field of printing media because of the trend of the present. It suggests that the origin of commodity competitiveness depends on the ability of cultural Contents using design. Cultural commodity is considered as strategy concepts in the more specific and realistic aspect than in the aspect of industrialization. This study introduce the case of Cellpark Co.,Ltd. which has successfully developed commodity design of World-cup cultural contents as a creating tools of innovative value connecting existed design method based on printing media with new method. This study gave the case which created Blue Ocean market through new expression method of design, products protection of contents design by patent registration, and licensing which many design firms often overlook.

Recently several hospitals have established a new nursing position so called, 'the nurse in charge of education (NCE).' The job description of NCE is to give a detail explanation on examination or test introduced to patients or a guide for those who are not familiar to hospital facilities at the out-patients level. The motivation of NCE position is the quality improvement in patient education on the sophisticated procedures or the follow up care for medical purposes to improve their compliances, as well in delivering services for outpatients or visitors in more informative and efficient way. The application of NCEA has been turned out positive and effective in patient satisfaction and unit management. However, special attention is brought to the scope and depth of the contents of education delivered by NCE which might overlap with the duty of physicians by the Medical Act. It is needed to clarify the role and job description of NCE in the context of Medical Act. The engagement of NCE to the Advanced Nursing Practitioner (ANP) is one of the possible solutions for a duty charge on patient education since ANP is a legislatively official position with higher license of RN at master level. Further discussion is needed to elaborate and arrange the details on the scope and content of patent education among health science professionals including RN, ANP and physicians.

Recording of the research procedure and results is the compulsory virtue to scientists. This ensures the objectivity and integrity of research and has become a cornerstone for a junior scholar. Furthermore, we can save time and efforts by avoiding duplication study. Recently on its patent application, the value of laboratory notebook is going to increase. However, there is a limitation to record a voluminous work in a traditional writing laboratory notebook. So, it could be an alternative proposal to convert that into an electronic work or develop an electronic laboratory notebook. Our journal has continuously pursued globalization. Laboratory notebook could be one of the key factors for that goal. In the present study, the authors reviewed the needs for laboratory notebook and tried developing a proto-type electronic laboratory notebook.
