However, relatively little is known about the characteristics of its taste. In this study, the taste compounds including nucleotides and their related compounds, free amino acids, trimethylamine oxide, trimethylamine, betaine and total creatinine were analyzed, and their roles in tasting activity were investigated. The amounts of IMP was 1.9 μmole/g, and the ratio of IMP to the total nucleotides and their related compounds was 39.6%. The great portion of free amino acids in the extractives of yellowfin puffer muscle was occupied by taurine, lysine, alanine and glycine in order, and their content was 79.1% of the total free amino acids. Among the organic bases, total creatinine was abundant, and its nitrogen content was 63.4% of total extractive nitrogen. According to the results of the omission test, the main constituents of the characteristic taste of yellowfin puffer could be assumed as free amino acids and 5'-mononucleotides.

BACKGROUND/OBJECTIVES: This study was designed to investigate the improvement effect of white ginseng extract (GS-KG9) on D-galactosamine (Ga1N)-induced oxidative stress and liver injury. SUBJECTS/METHODS: Sixty Sprague-Dawley rats were divided into 6 groups. Rats were orally administrated with GS-KG9 (300, 500, or 700 mg/kg) or silymarin (25 mg/kg) for 2 weeks. The rats of the GS-KG9- and silymarin-treated groups and a control group were then intraperitoneally injected Ga1N at a concentration of 650 mg/kg for 4 days. To investigate the protective effect of GS-KG9 against GalN-induced liver injury, blood liver function indicators, anti-oxidative stress indicators, and histopathological features were analyzed. RESULTS: Serum biochemical analysis indicated that GS-KG9 ameliorated the elevation of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) in GalN-treated rats. The hepatoprotective effects of GS-KG9 involved enhancing components of the hepatic antioxidant defense system, including glutathione, glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT). In addition, GS-KG9 treatment inhibited reactive oxygen species (ROS) production induced by GalN treatment in hepatocytes and significantly increased the expression levels of nuclear factor erythroid-2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) proteins, which are antioxidant proteins. In particular, by histological analyses bases on hematoxylin and eosin, Masson"s trichrome, α-smooth muscle actin, and transforming growth factor-β1 staining, we determined that the administration of 500 mg/kg GS-KG9 inhibited hepatic inflammation and fibrosis due to the excessive accumulation of collagen. CONCLUSIONS: These findings demonstrate that GS-KG9 improves GalN-induced liver inflammation, necrosis, and fibrosis by attenuating oxidative stress. Therefore, GS-KG9 may be considered a useful candidate in the development of a natural preventive agent against liver injury.

질량분석기로 사용되는 폴 트랩 내에서 보다 실제적인 이온운동을 예측해내기 위하여 약 2천 개의 다중입자의 궤적에 대한 계산을 실시하였다. 보다 정확한 질량 분석스펙트럼을 얻기 위하여 충돌확률에 대한 보다 정확하고 실질적인 함수 값을 도입하였다. 계산된 전산시늉의 결과들로부터 특히 작은 질량의 영역에 대한 분석을 할 경우 본 논문에서 제시된 바와 같이 매우 정확한 충돌확률이 고려되어야 함을 확인할 수 있었다. To predict the practical characteristics of ion motion in the paul trap as a mass spectrometer, the ion trajectories of the multi-particle(over than 2000 particles) were calculated. In order to expect more practical mass spectrum, the exact expressions for the collision probability was adopted. From the simulation result, we found that the exact collision probability has to be considered to analyze the materials existed in the low mass region.

To determine the characteristic double contrast barium enema findings of ileo-cecal and colonic tuberculosis and to make differential diagnosis from other bowel inflammatory disease. Sixty-seven patients confirmed as ileo-cecal and/or colonic-tuberculosis in six hospitals were evaluated retrospectively. The diagnosis was proven by endoscopic biopsy, surgery, and clinical follow up. Nine of 67 patients were excluded because radiologic findings were normal though endocopic biopsy examinations resulted in tuberculosis. Histopathological diagnosis were madein 58 cases as follows: endoscopic biopsy(n=29), operation(n=12), follow up examination(n=14), tissue culture(n=1), laparoscopic biopsy(n=2). There were 30 men and 28 females. The mean age were 36 yrs(range:16-67), 34 patients were in the second and third decade. The distribution of lesions, morphological characteristics, mucosal changes, ulcer shape and depth, associated with other tuberculous lesion, multiplicity were retrospectively analyzed in the findngs of double contrast barim enema. The commonest clinical symptoms were abdominal pain(n=35, 60%) and diarrhea(n=18, 31%). The chest radiography revealed association of pulmonary tuberculosis in 39 cases. Tuberculous lesions of other organs except chest were present in five cases. Double contrast barium enema findings showed a thickening and irregularity of intestinal mucosal fold(n=29, 50%), bowel contraction and/or shortening(n=26, 45%). There were small, nodular, superficial ulcers in the case of ulcer depth less than 2 mm in the depth. As many as 39 cases(67%) in this series had two or more lesions in the intestinal tuberculosis. The involved segment revealed symmetrical feature(n=21, 36%). Inflammatory pseudopolypoid lesions were noted in 30 cases(52%). The ileo-cecal region was involved in 38 cases(66%). The ascending colon(n=25, 43%) was the second commonest site with or without contiguous cecal involvement. Lesions in terminal ileum, ileo-cecal valve, transverse colon, descending colon and appendix were seen in 19, 18, 18, 12 and seven cases, respectively. Among 18 cases of ileo-cecal valve lesions, there were incompetency in nine cases(16%) and wide gapping in four cases(7%). In 14 cases, tuberculous enterocolitis was diagnosed by clinical follow-up and double contrast barium enema study. 12 out of 14 cases, the findings of double contrast barium enema of tuberculous enterocolitis were normalized after anti-tuberculous medication. However, two cases showed more aggravated state than before due to inappropriate treatment. Double contrast barium enema plays an important role in the diagnosis of tuberculous enterocolitis, determines the type, site and extent of the involvement and helps in treatment guide by using sequential studies.

Recently, an important controversal thesis in the Korea is defamation of 'public figure' on the press. The key criterion, defamation, relates to words or pictures which disgrace a person, so as to diminish his or her standing in the community. A defamatory expression tends to expose a person to hatred, redicule or contemt, and civil laws have evolved from the notion that citizens should be protected from this type of wrongful hurt, in order to preserve the essential dignity and worth of every human being. Most of all democratic countries in the world set out an appropriate balance between the human right to freedom of expression. Especially, public bodies of all kinds-including all bodies which form part of the legislative, executive or judicial branches of government or which otherwise perform public funtions-should be prohibited altogether from bringing defamation actions. This is in recognition of the vital importance in a democracy of open criticism of government and public authorites, the limited and public nature of any reputation these bodies have, and the ample means available to public authorities to defend themselves from criticism. But the Korea Supreme Court has not been reflect these principles. It was in 1989 that the notion of the 'public figure' was first cited in libel rulings in the Korea, but it was used only as a minor requisite. More interesting was that many cases in which the plaintiff's status was considered the 'public figure' were mainly referring to entertainers with an exemtion of such powerful elites as public officials and politicans. This case study treats two important concepts in libel litigation, the 'public figure' and the freedom of the press, in accordance with a Constitutional Court of Korea's decision in 1999(Case No.,97-265). This decision was motivated by the U.S. legal convention of considering the status of the plaintiff in libel cases to ensure the maximum press coverage of significant political issues. In conclusion, cognisant of the role of the media in furthering the public's right to know, in providing a forum for public debate on matters of public concern, and in acting as a 'public watchdog' to help promote government accountability; i) desiring to promote a better understanding of the appropriate balance between the right to freedom of expression and the need to protect reputation, ii) recommended that 'public figure' undertake appropriate action in their respective fields of competence to promote the widespread dissemination, acceptance of international law and standards.

실시간 광 BJTC 시스템 구현을 위한 신호 흐름 제어

황수용,차광훈,김호연 서울산업대학교 산업대학원 1993 大學院論文集 Vol.2 No.-

One of the most ridiculous issue of the moving target tracking system is real-time processing of the input scene so as to extract the target features and estirmate the target states but there are no way to solve this problem sensationally in a digital algorithm. Recently an optical approach for this problem is presented; named BJTC tracker. In this paper, we propose a hardware that can the control the JTC signal for the BJTC system and show the timing chart of the hardware system to prove the design method. We use the FPGAs, low-accesstime RAM, and high performance ADC and DAC. And we use NTSC type CCDs and monitors.
