This study is the analysis based on Prospect Theory for the North Korea’s mechanism of policy choices on the USS Pueblo Incident happened in 1968. The Kim’s reference points at the time of the USS Pueblo incident are externally to protect North Korea’s sovereignty, to strengthen the alliance with the U.S.S.R. and China in addition to maintaining the autonomy for national security, internally to consolidate the Kim’s autocratic power and to reinforce the revolutional power against the South Korea The USS Pueblo incident can be divided into two stages. The first stage is to seize of the USS Pueblo and the first response stage of the U.S.A. and North Korea. (from Jan. 16 to Feb. 1) At this stage, Kim estimated that the U.S.A. would not drive the situations to war because of her domestic and international political difficulties. In early January 1968, North Korea faced the difficult political situations due to her contradictory relationships with U.S.S.R. and China, the increase of consciousness to be encircled because of the establishment of the diplomatic relationship between South Korea and Japan, and the failure of the raid on Blue House by the North Korea’s guerrillas. In these situations, the information collection of the USS Pueblo on North Korea was a threat against North Korea’s security and a violation of North Korea’s sovereignty, and it was also a challenge against Kim. So Kim perceived the situations were in loss-domain on the basis of his 4 reference points and chose the risk-taking collision policy to seize of the USS Pueblo and to deny negotiation. The second stage is the negotiations between the U.S.A. and North Korea. (from Feb. 2 to Dec. 23). As all efforts were failed, the leadership of the U.S.A. could not help stopping the armed demonstration and sitting down on the table for the individual negotiations with North Korea. As the negotiations had been going on, the U.S.A. had somewhat conceded ‘3A’(Admit, Apologize, Assure) and North Korea could get the result to be admitted the North Korea’s sovereignty by the U.S.A. Kim had got the result to strengthen the alliance with the U.S.S.R. and to acquire her additional economical and military support, to improve the relationship with China, to enhance his internal & external prestige, to support the North Vietnam indirectly and to succeed in resulting in conflict between Korea and the U.S.A. These situations almost satisfied Kim’s 4 reference points. So Kim perceived the situations as gain-domain and decided to choose the risk-avoiding selection to conclude the negotiations. This study shows the effectiveness of Prospect Theory. It will be the short cut to grasp the reference points of North Korea’s leadership and the mechanism of policy choice and to cut or change its links in order to prevent and oppose the continuing North Korea’s provocation effectively. This study expects to contribute to this.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

The purpose of this study is to investigate the propriety of TMA clathrate as a cold storage medium. Particularly, this is to examine the extent of subcooling improvement when the additives are added to the TMA clathrate, because water used cold storage material has low phase change temperature and subcooling. This study has been analyzed and compared with TMA 30 wt% clathrate how phase change temperature, subcooling and specific heat in the various concentrations are changed. This results view to be improved phase change temperature and subcooling of TMA 30wt% as a cold storage medium, when it had some additive. Additionally, it is found that the additive must be controlled under available solution limit and study for new additive must be lasted to know its effect.

Background: Subclinical hypothyroidism(SCH) is a common biochemical abnormality which can be found in routine screening tests of thyroid function. We are increasingly faced with the question of whether its an indication for thyroxine replacement therapy. The effect of thyroxine replacement on lipid profile in SCH has aroused a great interest because of an association of overt hypothyroidism(OVH) with hyperlipidemia and increased risk of coronary artery disease. Method: We prospectively evaluated the changes in lipids and apoproteins before and after thyroxine replacement therapy in 23 patients with SCH and in 37 patients with OVH. We measured serum total cholesterol and triglyceride using autoanalyzer, high density lipoprotein(HDL) chole-sterol by dextran sulfate method, Apo A1 and Apo B by immunonephelometric assay. Results: Thyroxine replacement therapy significantly decreased total cholesterol, low density lipoprotein(LDL) cholesterol and apo B levels, but did not affect the level of triglyceride, HDL cholesterol or apo AI in patients with OVH. In SCH, thyroxine replacement therapy with the doses to normalize serum TSH concentrations also decreased significantly the level of cholesterol and LDL cholesterol albeit apo B levels did not change. Moreover, in most of patients with OVH (11 of 12) and in all of patients with SCH(5 of 5) who had had hyperchlesterolemia before treatment, thyroxine replament normalized their cholesterol and LDL cholesterol levels. Conclusion: In regard to the beneficial changes in blood lipid levels, patients with SCH should be treated, especially in cases who have other risk factors for the development of atherosclerosis. If thyroxine replacement only will reduce the incidence of coronary artery disease in SCH remains to be elucidated by long-term prospective studies(J Kor Soc Endocrinol 11:41-51, 1996).

Rice takes up phosphorous (P) as major nutrient source for its growth and development when grown under anaerobic water-logged soil conditions. To better understand the underlying mechanisms and to develop potential protein biomarkers of P-starvation, hydroponically-grown rice seedlings in the complete media and phosphorus absence (P-starvation) of phosphorous nutrient solutions were investigated for physiological and proteome changes. The P-starvation manifested significant reduction in root growth in three-week-old seedlings compared to respective complete media. Furthermore, P-starvation also showed increased activity of acid phosphatase in roots of one- and three-week-old seedlings, suggesting that experimental design is suitable for proteomics survey of P-starvation responsive proteins. Two-dimensional gel electrophoresis coupled with matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry analysis of total root protein from three-week-old seedlings identified 10 P-starvation responsive protein spots out of 140 high-quality protein spots. Identified 10 proteins were involved in metabolism and defense/stress response. Out of 10, 2 and 8 protein spots were found to be up- and down-regulated, respectively. Semi-quantitative reverse transcription polymerase chain reaction (RT-PCR) analysis of corresponding genes of four randomly selected proteins, including putative glyceraldehydes-3-phophate dehydrogenase (G3PDH, spot R1), S-adenosyl-L-methionine synthetase (SAMS, spot R4), ATP synthase subunit alpha (spot R6), and root-specific pathogenesis-related protein 10 (PR-10, spot R8), showed that just as protein abundance, these proteins are also regulated at the transcript level. Results suggest identified P-starvation responsive proteins are involved in maintaining nutrient homeostasis and/or associated with changes in root physiology under the absence of P.

To evaluate the in-vivo effects of mitomycin-C-polyglycolic acid composite(MMC-PGA) the disk: shaped composite were implanted into the peritoneal cavity of the Sprague-Dawley rats. The pathologic changes were examined at various time points up to 12 weeks. Initially the soft tissue around the inserted disks showed capillary congestion at 3 days. Inflammatory infiltrates with foreign body giant cells appeared from the 2nd week and reached peak response at 6-8 weeks. These reaction diminished prominently at 12 weeks. No specific pathologic change was found in the liver, the kidneys, and the heart. The above results suggest that the MMC-PGA composite can serve as a new device for intraperitoneal chemotherapy of various types of cancers.
