This experiment was conducted on the Experimantal Field of Cheju Univ. from November 1996 to June 1997. Object of this study was to clarify the fertilizer responses and to estimate genotypic, phenotypic and environmental correlations, heritabilities and path coefficients for some agronomic characters using 19 hulled oat cultivars including Olgwiri in accordance with different fertilizer levels. The heritabilities estimated for the days to heading, the culm length, the panicle length, culm diameter, the number of kernels per panicle, 1000-kernel weight and the grain yield per plant were high, and those for the days to maturity, the number of fillers and panicles per plant, and the panicle weight were medium, and that for the rate of effective tillering was low. Changes in heritability for the number of kernels per panicle and the 1000-kernel weight were small, and those for the days to maturity, the number of tillers and panicles per plant, panicle weight and the rate of effective tillering varied greatly on different fertilizer levels. With increasing fertilizer level, heritability of grain yield per plant was increased. The gram yield showed highly positive genetic correlations with the number of tillers per plant, with the number of panicles per plant and with the panicle weight, and, showed the negative correlation with the days heading. With increasing fertilizer level, the genotypic correlation coefficient between the panicle weight and the number of kernels per panicle was increased, and the genotypic correlation coefficients between the number of filler and panicles per plant, and between the grain yield and the number of fillers per plant and the rate of effective tillering were decreased. The phenotypic correlation coefficient between the grain yield and the number of tillers per plant and panicles per plant showed highly positive values, and the changes in phenotypic correlation coefficient for different fertilizer levels had no definite tendency. The characters of which direct effect estimates were high versus the grain yield per plant were the number of panicles per plant on non-fertilizer plot, the number of tillers per plant on decreased fertilizer plot, the number of panicles per plant on standard fertilizer plot, and the panicle weight on increased fertilizer plot. Genotypic correlations and direct effects of the panicle weight and the number of panicles per plant versus the grain yield per plant were high in most treatments, that is, these characters had an influence on the grain yield.

Most recently, CP(Cellular phone) has been one of the most important technologies in the IT(Information Tech-nology) fieid,and it is situated in a position of great importance industrially and economically. To produce the best CP in the world, a new technological concept and its advanced implementation technique is required, due to the extreme level of competition in the world market. The RT(Robot Technology) has been developed as the next generation of a future technology. Current robots require advanced technology, such as soft computing, human-friendly interface, interaction technique, speech recognition, object recognition etc.unlike the industrial robots of the past. Therefore, this paper explains conceptual research for development of the RCP(Rpbptic Cellular Phone), a new technological concept, in which a synergy effect is generated by the merging of IT & RT. RCP infra consists of RCP^(Mobility), RCP^(Interaction), RCP^(Integration) technologies. For RCP^(Mobility) human-friendly motion automation and personal service with walking and arming ability are developed. RCP^(Interaction) ability is achieved by modeling an emotion-generating engine and RCP^(Integration) that recognizes environmental and self conditions is developed. By joining intelligent algorithms and CP communication network with the three base modules, a RCP system is constructed. Especially, the RCP mobility system is focused in this paper. RCP^(Mobility) is to apply a mobility technology, which is popular robot technology, to CP and combine human-friendly motion and navigation function to CP. It develops a new technological application system of auto-charging and real-world entertainment function etc. This technology can make a CP companion pet robot. It is an automation of human-friendly motions such as opening and closing of CPs, rotation of antenna, manipulation and wheel-walking. It's target is the implementation of wheel and manipulator functions that can give service to human with human-friendly motion. So, this paper presents the definition, the basic theory and experiment results of the RCP mobility system. We confirm a good performance of the RCP mobility system through the experiment results.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

Chan Hee Park,Hyung Woo Lim,Hyun Woo Kim,Wook Gyo Lee,Jong Yul Roh,Mi Yeoun Park,E-Hyun Shin 한국응용곤충학회 2014 한국응용곤충학회 학술대회논문집 Vol.2014 No.04

The intracellular endosymbiont bacterium Wolbachia is currently considered the most abundant in arthropods and has also been isolated from nematodes, amphipods, isopods, mites and spiders. Recently, Wolbachia-based research was focused on the control of disease vector-population, such as several mosquitoes such as genus Aedes and Anopheles which cause dengue fever and malaria, respectively. For the analysis of regional difference between vector mosquito Aedes albopictus and Wolbachia, we selected different regions and collected Ae. albopictus which were distinguished with mountain chain and waterway. Whole genomic DNA were extracted from collected specimens with 9 regions. PCR analysis and sequencing were accomplished in each specimen for Wolbachia detection and identification using WSP gene. As a results, almost mosquitoes were infected with two strain of Wolbachia both wAlbA and wAlbB. However, regional separation of vector mosquitoes, wAlbA strain of Wolbachia were showed more than 98% sequence similarity. In this study, we first reported that Wolbachia infection and type of Wolbachia in Korea and endosymbiont Wolbachia was showed highly sequence homologies.

<P>In contrast to CD34, vascular endothelial-cadherin (VE-cadherin) is exclusively expressed on the late endothelial progenitor cells (EPC) whereas not on the early or myeloid EPC. Thus, VE-cadherin could be an ideal target surface molecule to capture circulating late EPC. In the present study, we evaluated whether anti-VE-cadherin antibody-coated stents (VE-cad stents) might accelerate endothelial recovery and reduce neointimal formation through the ability of capturing EPC.</P>
