Wide pressure range condensation modeling on pure steam/steam-air mixture inside vertical tube

The elimination of active systems and their replacement with passive systems are emphasized to improve a system reliability in advanced nuclear power plants such as SMART. For accident situations, a condensate heat exchanger having vertical tubes is an ultimate heat sink to remove residual heat generated in the core. To adequately analyze the system behaviors, a realistic condensation model with pure steam or a steam-air mixture in the condensate heat exchanger is important for the various thermal hydraulic conditions.Improved correlations are proposed to analyze the thermal hydraulic behaviors for wide pressure conditions of up to 6 MPa. For a validation of the condensation heat transfer for the condensate heat exchanger tube side, simulations of the UCB (University of California at Berkeley) and POSTECH (Pohang University of Science and Technology) condensation experiment are carried out, and the results are compared with the experimental data. For pure steam conditions, the correlations predict well or under-predict slightly the UCB experimental results and predict the POSTECH experimental results within 25%. The improved correlation predicts that the condensation heat transfer coefficient decreases as the system pressure increases as shown the POSTECH experiment.

Technological catch-up and the role of universities: South Korea’s innovation-based growth explained through the Corporate Helix model

Linkages between industry and university have become crucial for knowledge discovery and driving industrialization within fast-paced global competition and technological evolution. This study offers a pair-wise cross-case analysis of the transitioning of Pohang University of Science and Technology (POSTECH) and Sungkyunkwan University (SKKU) to become entrepreneurial universities through the Corporate Helix model. POSTECH and SKKU demonstrated divergent routes but convergent outcomes in technological catch-up during the double helix formation stage. Through the relationship triad POSTECH shares with the Industry and Government after being established by Pohang Steel Company, it has been committed to launching Korea into the forefront of innovative science and technology in the twenty-first century. As a result of its acquisition and intensive investment from Samsung for almost over two decades, SKKU has become one of the top schools in South Korea while interacting closely with the industry and government to cultivate the efficacy of South Korea’s national innovation system. The Corporate Helix model takes into account the university which lacks the resources and capability to become entrepreneurial and to participate in a nation’s technological catch-up to innovation-based growth. The cases of POSTECH and SKKU offer key propositions that a university can be established or acquired by the industry and through this partnership undergo transformation to become entrepreneurial.

KIAA1114, a full-length protein encoded by the trophinin gene, is a novel surface marker for isolating tumor-initiating cells of multiple hepatocellular carcinoma subtypes

Identification of novel biomarkers for tumor-initiating cells (TICs) is of critical importance for developing diagnostic and therapeutic strategies against cancers. Here we identified the role of KIAA1114, a full-length translational product of the trophinin gene, as a distinctive marker for TICs in human liver cancer by developing a DNA vaccine-induced monoclonal antibody targeting the putative extracellular domain of KIAA1114. Compared with other established markers of liver TICs, KIAA1114 was unique in that its expression was detected in both alpha fetoprotein (AFP)-positive and AFP-negative hepatocellular carcinoma (HCC) cell lines with the expression levels of KIAA1114 being positively correlated to their tumorigenic potentials. Notably, KIAA1114 expression was strongly detected in primary hepatic tumor, but neither in the adjacent non-tumorous tissue from the same patient nor normal liver tissue. KIAA1114high cells isolated from HCC cell lines displayed TIC-like features with superior functional and phenotypic traits compared to their KIAA1114low counterparts, including tumorigenic abilities in xenotransplantation model, in vitro colony- and spheroid-forming capabilities, expression of stemness-associated genes, and migratory capacity. Our findings not only address the value of a novel antigen, KIAA1114, as a potential diagnostic factor of human liver cancer, but also as an independent biomarker for identifying TIC populations that could be broadly applied to the heterogeneous HCC subtypes.

Campus in English or campus in shock?

With the acceleration of globalization, universities in East Asia are increasingly under pressure to compete internationally, and ‘internationalization’ of tertiary education in the region has topped the education reform agenda of each government (Mok &amp; James, 2005). In an effort to join the league of world-class universities and attract international students, East Asian universities have expanded the number of English-medium lectures (EMLs) offered as part of their internationalization strategy, and no country has embraced the move more than Korea (Newsweek, February 26, 2007). As of 2010, all the classes at the Korean Advanced Institute of Science and Technology (KAIST) are conducted in English only and 93 percent of classes at the Pohang University of Science and Technology (POSTECH), the nation's two best science and engineering universities, with rates of EML averaging around 10 to 30 percent among the top 7 universities in Korea as of the first half of 2008 (Chosun Ilbo, March 10, 2008). Reforms of Korean universities characterized by the introduction of EMLs have been praised by many local as well as top international media such as theNew York Timesand theScience Magazine. Often lost amid the hype, however, are the challenges facing local students in learning complex material in English, a language which most have learned only as a foreign language and to limited levels of proficiency. This article compares opinions expressed in the mainstream media with those from university presses run by student organizations that have been most active in expanding English-medium programs by analyzing articles related to EMLs. The aim of this comparative research is to find out if there are any observable differences in views presented by these two types of print media, in an attempt to shed light on the move to EMLs in this exclusively monolingual country.

Yongmin Kim: Setting the Pace for Bioengineers

Early in his career, Yongmin Kim adopted an interdisciplinary approach to research that a more ego-driven researcher would have shied away from. He teamed with statisticians, electrical engineers, medical doctors, computer scientists, and industry executives to produce a steady stream of around 450 publications and a slew of innovations to medical imaging equipment that he has often had the pleasure of seeing put to use in hospitals in as short as two years. But Kim did not sit back and bask in his accomplishments. The moment he reached a goal, he set his sights on the next one. Having helped build the University of Washington's Bioengineering Department, where he led students and faculty for 29 years, the IEEE Fellow and former Engineering in Medicine and Biology Society (EMBS) president resigned his tenured faculty position and set out to meet another challenge: serving as president of South Korea's Pohang University of Science and Technology (POSTECH).

Corporate helix model: the industry and triple helix networks

A different type of university-industry-government relations took place in South Korea. In the triple helix model the entrepreneurial university becomes a key element of the innovation system. However, most universities in the world would not be autonomous in this network relationship. This paper proposes "The Corporate Helix Model", in which the university is established or acquired and transformed into the corporate/entrepreneurial university by the corporation prior to playing as an independent player in the triple network relationship. The model is postulated by a case study of establishment of Pohang University of Science and Technology (POSTECH) by Pohang Steel Company (POSCO).
