차세대 원자로 설계개발에 사용되는 설계전산코드에는 원자로 계통설계, 주요 기기설계등을 포함하여 약 440여개에 달한다. 이들 전산코드에 사용되는 프로그래밍 언어는 FORTRAN, COBOL, C/C++를 비롯하여 BASIC등 그 종류가 다양하다. 특히 개발된 주요 설계코드들이 구동되는 플랫폼은 그 종류가 훨씬 다양하여 같은 유닉스를 기반으로 한 프로그램도 H/W 제작사에 따라 전혀 동작되지 않음은 물론 심지어는 같은 제작사라하더라도 서로 다른 OS를 가지는 경우에는 사용할 수 없게 되어있다. 이들 원전설계전산코드들이 갖는 안정성 및 신뢰성, 유니크한 보안특성을 어느 정도 인정한다. 하더라도 향후 이들을 유지보수하거나 성능향상을 꾀한다든지 이들과 어울리면서 새로운 전산프로그램을 추가 개발하려고 할 경우 여러 가지 예기치 않은 문제가 발생할 수 있다. 최근 인터넷의 확산과 더불어 각광을 받기 시작한 JAVA는 이것이 갖는 특유의 객체지향성, 플랫폼 독립성 및 견고성, 이식성등으로 견주어 볼때 이를 향후 원전 설레코드의 개발에 적용할 경우 매우 이상적일 것으로 예상된다. 더구나 원전설계와 같이 고도의 기술집약적이면서도 여러 설계관련사가 대응되는 다원화된 업무구조를 갖는 경우 다양한 플랫폼을 지원하는 JAVA 프로그래밍이야 말로 최선의 선택이라 할 수 있다.

Purpose: In prior study, we synthesized $^{99m}Tc$-galactosylated chitosan (GC) and performed in vivo biodistribution study, showed specific targeting to hepatocyte. The aim of this study is to evaluate the labeling efficiency and cytotoxicity of modified galactosylated chitosan compounds, galactosyl methylated chitosan (GMC) and HYNIC-galactosylated chitosan (GCH). Materials and Methods: GC, GMC and GCH were synthesized and radiolabeled with $^{99m}Tc$. Then, they were incubated for 6 hours at room temperature and human serum at $37^{\circ}C$. Labeling efficiencies were determined at 15, 30 m, 1, 2, 3 and 6 h after radiolabeling. To evaluate cytotoxicity, MTT assay was performed in HeLa and HepG2 cells. Results: In comparison with them of $^{99m}Tc$-GC labeling efficiencies of $^{99m}Tc$-GMC were significantly improved (100, 97 and 89%) in acetone and 96.3, 95.8 and 75.6% in saline at 15 m, 1 and 6 h, respectively). Moreover, $^{99m}Tc$-GCH showed more improved labeling efficiencies (>95% in acetone and human serum and >90% in saline at 6 h). In MTT assay, cytotoxicity was very low and not different from that of controls. Conclusion: These results represent that these compounds are radiochemically compatible radiopharmaceuticals, can be used in hepatocyte specific imaging study and in vivo gene or drug delivery monitoring.

The advancement of Information and Communication Technology (ICT), along with the expansion of government and private investment in startup discovery and funding, has led to the emergence of startups seeking to generate outstanding results based on innovative ideas. As successful startups serve as role models, the number of aspiring entrepreneurs preparing to launch their own startups continues to increase. However, unlike entrepreneurs who challenge themselves with serial entrepreneurship after experiencing success, early-stage startups face various challenges such as team building, technology development, and fundraising. Accelerators play a dual role of mentor and investor by providing education, mentoring, consulting, network connection, and initial investment activities to help startups overcome various challenges they face and facilitate their growth. This study investigated whether there is a correlation between the characteristics of startups and their entrepreneurial performance, and analyzed whether accelerators mediate the relationship between startup characteristics and entrepreneurial performance. A total of 11 hypotheses were proposed, and a survey was conducted on 302 startup founders and employees located across the country, including the metropolitan area, for empirical research. SPSS 23.0 and Amos 23.0 were used for statistical analysis. Through this study, it was found that factors such as innovation, organizational culture, financial characteristics, and learning orientation among the characteristics of startups, rather than having a direct impact on entrepreneurial performance, are linked to entrepreneurial performance through the role of accelerators. By analyzing the impact factors of startup characteristics on entrepreneurial performance, this study presents research on the role of accelerators and provides institutional improvements. It is expected to contribute to the expansion of investment and differentiated acceleration programs, enabling startups to seize the market and grow stably in the market.

In this paper, we carried out the numerical examination of the initial value setting-up method to extend the range of optimal step parameter in a adaptive system which is controlled by LMS algorithm. For initial value setting-up methods, the general method which select the initial value randomly and the other method which applies the approximate value obtained from the direct method to initial value, were used. And then, we compared to the ranges of step parameter setting, the convergence speeds of mean-square-error, and the stabilities during the convergence process when the initial values were applied to the optimal directivity synthesis problem. According to the numerical simulation results, the initial value setting-up method by means of the direct method provides wider range for the step parameter, more efficient capability for convergence and stability, and more error correction ability than the general method.
