  • To select potent probiotics from lactic acid bacteria in Yulmoo Kimchi, an in vitro and stimulated human intestinal model system (SHIMS) test were performed. One Leuconostoc mesenteroides strain from five strains of Yulmoo Kimchi and one Lactobacillus plantarum from 12 strains of KCTC and KCCM were selected according to survival in acidic and bile salts conditions. Between the two species, Leu. mesentroides displayed higher survival activity in a SHIMS test. The strain was identified as Leu. mesentroides by 16S rRNA sequencing and was designated as Leu. mesentroides K01.

  • In this study, nonhierarchical K-mean cluster analysis is used to classify the types of 230 local governments and the Mann-Whitney U test and Kruskal-Wallis analysis are used to analyze the characteristics of pedestrian accidents by region types. With empirical analysis of pedestrian accidents, this study suggests improvements of walking environments reflecting local characteristics. Type 1-A (relatively dominant urban commercial areas), Type 1-B (predominantly urban residence) and Type 2 (rural areas) have been classified using nonhierarchical K-mean cluster analysis. According to the results, pedestrian accident rate on community roads was more than 60% for all types and incidence rate in rural areas was higher than that in urban areas. In addition, pedestrian accidents of Type 1-B have been found to occur more frequently than Type 2 in intersections and crossings, while the number of roadside casualties for Type 2 was highest.

  • Object : This is a study of acute stage stroke patients designed for comparison of combined Eastern and Western medical treatments and Oriental treatments alone. Methods : 51 patients were diagnosed by Brain-CT and Brain-MRI scan as having suffered stroke. They had entered Dong-eui hospital within seven days of attack, and remained over seven days, all between November 2002 and August 2003. Patients were divided into two groups: a group treated with both Eastern and Western medical treatments, and a group treated only with Oriental medical treatments (but examinations were done and medications were given in hypertension, Diabetes Mellitus and so on). Results : The Eastern-Western medical treatment group showed significant changes in NIHSS. A rate of improvement figure of 24.94% was obtained for the Eastern-Western medical treatment group, and for the Oriental medical group a figure of 7.84% was obtained. Conclusion : The East-West medical treatment group had significant rate of development that measure for NIHSS by treated comparatively dependent patients. And oriental medical treatment group had significant rate of development that measure for NIHSS by treated comparatively independent patients. The NIHSS measure for the Eastern-Western medical treatment group shows a significant rate of improvement for relatively dependent patients, and the NIHSS measure for the Oriental medical treatment group shows a significant rate of development for relatively independent patients.

  • Allium hookeri, a member of the onion family, has long been mainly cultivated for food and medicinal use in Southeast Asian countries, owing to its various biological properties. However, no studies of the anti-oxidative effects of fermented A. hookeri root extracts have been conducted to date. Therefore, this study investigated the effect of different starter cultures on the antioxidant activities of hot water extract of A. hookeri root by using the following five strains: Lactobacillus acidophilus, Bifidobacterum longum, Enterococcus faecium, Streptococcus thermophilus, and Saccharomyces cerevisiae. DPPH and ABTS radical scavenging activity, total phenolic acid contents, and total antioxidant capacity were higher in the hot water extract of A. hookeri root fermented with starter cultures than those of A. hookeri root. Among hot water extract of A. hookeri root fermented with starter cultures, fementing with S. cerevisiae showed the highest antioxidant activities. The results of this study provide new evidence of the anti-oxidative properties of A. hookeri root with starter cultures, indicating that it may be highly valuable as a natural product owing to its high-quality functional components.

  • The variations of the anther and pistil length of some rice cultivars at the different planting density and fertility levels were tested and their inheritance mode was studied. The anther length of a spikelet on a secondary panicle branch was longer than the one of a spikelet on a primary panicle branch. In the cultivar Z97B, both the anther and the pistil length were increased slightly along the increased plant-ing spacings, But, in the cultivar IR43 no general tendency was observed. The fertilizer levels applied n the field did not affect both the anther and pistil length of a given cultivar. In a cross of IR56/IR8, the anther length showed continuous variation with longer anther being recessive in the F2 population. While, the pistil length showed a continuous variation with longer pistil being over-dominance. In all of the crosses which IR56 involved, the general and specific combining abilities were high for both the anther and pistil length. The broad sense heritability for anther length was 0.46, and for pistil length was 0.88. The correlation coefficients of anther length and pistil length were 0.33 for phenotypic and 0.44 for geno-typic.

  • Liver is generally known as an organ which is most commonly involved by the metastic tumors. According to the tendency of using fine needle aspiration in the diagnosis of hepatic tumors, the differentital diagnosis between hepatocellular carcinoma and metastatic carcinoma frequently has been a main issue in the poorly differentitated cases, especially to the pathologists of Korea, an endemic area of hepatocellular carcinoma. Until now the problem has been usually solved by the comparison of cytologic characteristics of their tumor cells but not by background cytologic features which rarely have been studied. We observed the background cytologic features helpful for the differential diagnosis through the analysis of 20 cases who had confirmed primary cancer and were diagnosed as metastatic carcinomas in the liver by fine needle aspiration cytology. Twenty cases included 9 adenocarcinomas, 7 spuamous cell carcinomas, 1 small cell carcinoma, 1 carcinoid, 1 adenoid cystic carcinoma, and 1 renal cell cacinoma. Analysis of background cytologic features revealed that 77% of adenocacinoma cases showed benign mesenchymal components and hepatocytes and spuamous cell carcinoma cases disclosed benign mesenchymal tissue (71%) and necrosis (57%), Remaining cases showed variable combinations of benign mesenchymal component, necrosis, hepatocytes, and bile duct epithelial cells. No case revealed atypical hepatocytic naked nuclei, a useful cytologic finding of hepatocellular carcinoma. In summary, the background cytologic features more commonly observed in metastatic carcinomas than in the hepatocellular carcinoma were benign mesenchymal components, hepatocytes, necrosis, and bile duct epithelium. The endothelial cells and hepatocytic naked nuclei, two relatively specific findings of hepatocellular carcinoma were not observed except for renal ceil carcinoma. Above background cytologic features are thought to be helpful for the differential diagnosis between the hepatocellular carcinoma and various metastatic carcinomas in the poorly differentiated cases.

  • A case of poorly differentiated "insular" carcinoma of the thyroid is presented and discussed with references to the literature. Un fine needle aspiration cytology of our case, the aspirates were highly cellular with tumor cells appearing as dispersed isolated cells as well as in dense clusters and syncytial formations. Occasional microfollicles containing colloid were evident. Most of nuclei were fairly uniform with considerable variability and a few showed definite atypical features. Nuclear grooving was additional features. Necrotic debris was not seen. Our cytologic findings were correlated well with histology, confirming typical insular pattern of tumor cells with the presence of occasional pleomorphic cells and papillary carcinoma-like features. With much attention to cytological features of insular carcinoma, it would be possible to diagnose a preoperative suggestive diagnosis, even though not definitive.

  • Donghae City - Ulleung Island Line (DC-UI Line) is a representative line for underwater and geoacoustic modeling in the middle western East Sea. In this line, an integrated model of P-wave velocity is proposed for a low-frequency range target (<200 Hz), based on high-resolution seismic profiles (2 - 7 kHz sonar and air-gun), shallow and deep cores (grab, piston, and Portable Remote Operated Drilling), and outcrop geology (Tertiary rocks and the basement on land). The basement comprises 3 geoacoustic layers of P-wave velocity ranging from 3750 to 5550 m/s. The overlying sediments consist of 7 layers of P-wave velocities ranging from 1500 to 1900 m/s. The bottom model shows that the structure is very irregular and the velocity is also variable with both vertical and lateral extension. In this area, seabed and underwater acousticians should consider that low-frequency acoustic modeling is very range-dependent and a detailed geoacoustic model is necessary for better modeling of acoustic propagation such as long-range surveillance of submarines and monitoring of currents.

  • For a systematic research of the history of Chinese roadside trees, this study analyzed various ancient writings of China according to following topics; the philosophical backgrounds and diverse species of Chinese roadside trees in different periods, as well as the management systems and existent remains of ancient Chinese roadside trees. The analyses draw the following conclusion. First, the thoughts from Lao-tzu, Chuang-tzu, Mo-tzu, Mencius and Guan-tzu from Hundred Schools of Thought of Warring States Period had laid certain impact on the fundamental attitude of the Chinese roadside tree management system. Secondly, various and different species of Roadside Trees were planted from each time period: amongst all, Willow trees were the most common, and Pine trees to be the next common. Besides, fruit trees such as peach trees and plum trees had been largely selected as roadside trees from the Zhou dynasty to the Ming dynasty. Thirdly, the names of roadside trees and the government officials who managed the roadside trees were different in each era. Fourthly, the oldest existent remain of roadside trees in China, which dates back over 2000 years, is located in Jiange Cuiyun Corridor of Sichuan province.
