INTEREST GROUPS AND FOREIGN POLICY IN SOUTH KOREA - A CASE STUDY
SANGHYUN YOON 서울대학교 국제학연구소 1999 Journal of International and Area Studies Vol.6 No.1
This article analyzes the role of interest groups in South Korean foreign policy with a particular reference to ‘Nordpolitik’, the diplomatic initiatives taken by the Roh Tae Woo government to improve the country’s relations with the communist countries north of its borders. More specifically, this work hopes to show that South Korea’s interest groups, such as the political parties, the military, the business circle, the media, and the anti-communist organizations, gained some measure of autonomy in the wake of ‘June 29 Declaration’ of 1987, enough to voice their views on many foreign policy issues including those relative to Nordpolitik, but they had a minimal success in affecting Nordpolitik. It hopes to shed some light on the interacting between interest groups and foreign policy in a typical society undergoing a profound transformation from a authoritarian system to a democracy. It will be a very interesting case study in the barren field of the relationship between interest groups and foreign policy decision-making in South Korea.

<P><B>Abstract</B></P> <P>Electrospun and ethanol-dispersed polystyrene-poly(styrene-co-maleic anhydride) (PS-PSMA) nanofibers (NFs) were used as a platform for the selective capture and three-dimensional culture of EpCAM-positive cells in cell culture medium and whole blood. The NFs were treated with streptavidin to facilitate bond formation between the amino groups of streptavidin and the maleic anhydride groups of the NFs. A biotinylated anti-EpCAM monoclonal antibody (mAb) was attached to the streptavidin-conjugated NFs via the selective binding of streptavidin and biotin. Upon simple mixing and shaking with EpCAM-positive cancer cells in a wide concentration range from 10 to 1000,000 cells per 10mL, the mAb-attached NFs (mAb-NFs) captured the Ep-CAM positive cells in an efficiency of 59%-67% depending on initial cell concentrations, with minor mechanical capture of 14%-36%. Captured cells were directly cultured, forming cell aggregates, in the NF matrix, which ensures the cell proliferation and follow-up analysis. Furthermore, the capture capacity of mAb-NFs was assessed in the presence of whole blood and blood lysates, indicating cluster formation that captured target cells. It is anticipated that the antibody-attached NFs can be employed for the capture and analysis of very rare EpCAM positive circulating cancer cells.</P> <P><B>Graphical Abstract</B></P> <P>Polystyrene-poly(styrene-co-maleic anhydride) (PS-PSMA) electrospun nanofibers (NFs) conjugated by anti-EpCAM monoclonal antibody is presented as an integrative platform for target cell capture and culture. The developed NFs has inter-fiber space for efficient selective cell capturing in wide concentration range of cell containing suspensions. Captured cells could be directly cultured in the NFs matrix, to ensure a cell culture environment.</P> <P>[DISPLAY OMISSION]</P>

Citrus canker caused by Xanthomonas citri is a notorious disease affecting a decrease in fruit productivity and quality. Citrus export to USA is also prohibited by the disease. Therefore, development of citrus canker resistant variety is essential and exploitation of markers for molecular breeding is urgent. To develop DNA molecular markers, we performed whole genome resequencing for 8 varieties: 4 citrus canker resistant varieties including C. hybrid ‘Kioymi’ and 4 citrus canker susceptible varieties including C. iyo ‘Miyauchiiyokan’. In total, 642 polymorphic SNPs were detected between resistant and susceptible varieties. Of the 642 SNPs, 50 SNPs were preferably selected based on integrative genomics viewer. To apply the markers in a broad range of citrus variety, we performed genotyping with 6 other varieties very well known as citrus canker resistant and susceptible varieties in addition to previous mentioned 8 varieties. Three of the 50 SNPs were identified as a marker to distinguish citrus canker resistant varieties from susceptible varieties. Secondly, we developed molecular markers to apply for F1 lines crossed by ‘Kiyomi’ and ‘Miyauchiiyokan’. Of the 50 SNPs, we identified 2 SNP markers to distinguish between F1 resistant and susceptible lines. One of them is a resistance gene that plays a role in plant defense mechanism. In this study, we developed 5 molecular marker candidates possible to apply for molecular breeding to develop citrus canker resistant variety. We are working on development of candidate markers related to citrus canker.

Ramie (Boehmeria nivea L. Gaudich.) is a hardy perennial herbaceous plant of the Urticaceae family and has been grown as a fiber crop in several countries including Korea for many centuries. Ramie leaves also have been traditionally used as a major ingredient of a type of rice cake called ‘Song-pyun’ in the Southwest area of Korea, especially Yeong-Gwang province. Despite its economic importance, the molecular genetics of ramie have not been studied in detail yet. Genetic resources of ramie were widely collected from domestic local sites by Bioenergy Crop Research Center (RDA) and Yeong-Gwang Agricultural Technology Center. For the systematic and efficient management of the genetic resources, we developed microsatellite molecular markers of ramie. To do this, we generated microsatellite-enriched genomic DNA libraries using magnetic bead hybridization selection method. 216 contigs containing microsatellite repeat motif were generated using nucleotide sequences of 376 clones from the libraries. Primer sets were designed from the flanking sequences of the repeat motif. Finally, we selected 26 microsatellite markers, possibly showing polymorphism among the genetic resources. Results on the genotype analysis of the ramie genetic resources using the microsatellite markers will be presented.
POLITICAL OBSTACLES TO GLOBALIZATION - THE DAEWOO-THOMSON AFFAIR
SANGHYUN YOON,HARVERY B,FEIGENBAUM 서울대학교 국제학연구소 1997 Journal of International and Area Studies Vol.4 No.1
This paper examines some political contstraints which limit the process of globalization. While economic theory would predict that firms locate the various stages of production of their products in those countries demonstrating clear comparative advantages. and while intra-firm trade data shows that multinational firms do, by and large, try to globalize their production, there are occasional political obstacles to such strategies. Many Korean firms have expanded into Europe for economic reasons, but the case of Daewoo Electronics ill fated attempt to purchase Thomson shows that analysts must take political. as well as economic conditions into account before the process of globalization can be understood.

Renewable energy systems including piezoelectric, thermoelectric, and photovoltaic devices have been intensively consideredfor the for the internet of things. Small energy sources with sustainable and robust properties for sensors, actuators,and communications were indispensable for the next industrial revolution. In this research, Mn doped PbZrTiO3thick filmspiezoelectric renewable energy harvesters were prepared and employed for the sustainable energy sources for the energyharvesters. Nano sized powders were prepared by the high energy ball milling process. Calcination and sintering processeswere sequentially processed for the device applications. Generated output energies were measured and tested by the impedancematching circuits and applied to the energy sources.
