Kwon,Byung-Sun,Shin,Jeong-Sik,Park,Hee-Jin,Shin,Jong-Sup,Choi,Seong-Yu 한국자원식물학회 2003 Plant Resources Vol.6 No.1

To determine as optimal sowing time of forage rape in spring time in southern areas of Korea, forage rape cv. Velox, the highest yielding variety among introduced varieties of forage rape, was grown under five different sowing times. Yield components such as plant length, number of branches and number of leaves etc. were higher at the sowing time of Mar. 15 and Mar. 25. The plants sown at Mar. 15 and Mar. 25 also showed highest fresh and dry matter yield. When plants were grown under later sowing time, they showed higher values in content of crude protein and lower values in contents of crude fiber such as Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), cellulose and lignin. There was no relationship between variation of In Vitro Dry matter Digestibility (IVDMD) and sowing time. The plants sown at Mar. 15 and Mar. 25 showed highest digestible dry matter yields.

With its rapid modernization and unparalleled speed of aging, South Korea faces the need for dramatic increase in its supply of nursing homes. Among the spacial components of nursing homes, residential units are considered as an essential part because the older person in nursing homes usually spend most of their time in residential units and the nursing homes are mainly composed of various residential units. It is necessary, therefore, to prepare a guideline for the plan of residential units in order to design the healthy and efficient nursing homes. This paper has first identified the concept of residential unit and analyzed 66 cases in the 62 nursing homes from 4 countries. And 4 nursing homes in Korea have been surveyed for the in-depth study. On the basis of this analysis, architectural prototypes of residential units have been proposed and the architectural characteristics of them have been compared analytically.

This study was conducted to investigate the relationships between yearly variations of meteorological elements and yearly variations of productivity in rice. In addition, correlation coefficients among yield and yield components were used to find out the relationships between meteorological elements and productivity. Yearly variation of the mean air temperature in May was large with coefficients of variation(C.V.) of 25.0%, but the variation of the duration of sunshine in May were relative small. No. of panicles per hill and 1,000 grains wt. of brown rice were great with C.V. of 21.1, 19.7%, respectively, brown rice yield show more or less C.V. of 5.5% and milled rice show still less variation. Correlation coefficients between temperatures in period of cultivation from May and yield were positive correlations. Correlation Coefficients between precipitation in period of cultivation from Sep. to Oct. and yield are positive correlations. Correlation coefficients amount the panicle length, no. of panicles, no. of spikelets, ratio of ripened grains, 1,000 grains wt. of brown rice, milled rice yield, brown rice yield and milled rice yield were positively significant at the level of 1 %, respectively.

Kwon,Byung-Sun,Shin,Jeong-Sik,Shin,Dong-Young,Hyun,Kyu-Hwan,Park,Hee-Jin,Sin,Jong-Sup,Seong-Kyu 한국자원식물학회 2003 Plant Resources Vol.6 No.2

To find out the optimum fertilizer level for high yielding variety, Velox, experiment was conducted with 15 compositions of fertilizer levels at the experiment field of forage crop in Sunchon National University from Mar. 2000 to Aug. 2000. The effects of nitrogen fertilizer on plant growth were significant but increasing rate of application in potassium and phosphate fertilizers above 6 kg/a had negligible effects on plant growth. The optimum nitrogen application level of fertilizers turned out to be 16-6-6 kg/l0a of N-P2O5-K5O. Content of crude protein was highest and that of crude fiber such as NDF, ADF, cellulose and lignin were lowest at this rate of fertilizer application. Furthermore, IVDMD was high and dry matter yield were highest at the optimum raterate

Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

The cytotoxic T lymphocyte(CTL) are an important component in host defense mechanism against viral infection. They can recongnize virus-derived peptides presented by the ClassⅠ MHC molecule at the cell surface of the infected cells. On searching for effective CTL epitopes of hepatitis B virus(HBV), we synthesized a distinct set of 9-10 mer peptide containing amino acid sequence of hepatitis B virus surface proteion that are selected on the basis of a computer modeling and the previously described HLA-A2 specific motifs. Binding assay of the synthetic peptides to HLA-A2 molecules using human antigen processing defectantn T2 cells showed what 3 out of 4 synthetic peptides enhaced the expression of HLA-A2 molemule on T2 cell surface. Two anchor positions, namely P2 and P9(or P10) appeared to play a decisive role for binding. Structural chacteristics of the peptides addressed by molecular dynamics simulation was analysed and compared. These peptides also parially triggerd CTL isolatied frmo human peripheral blood mononuclear cells of HBV positive patients, and the response was peptide-specific. These results showed that negatively-charged amino acid residue at P2 hampered binding affinity of the peptides to HLA-A2 molecules, and that binding affinity of the peptides are not always reflected by thier immunogenicity among natural T cell repertoire.

The authors analyzed 53 cases with spontaneous intracerebellar hemorrhage diagnosed by brain CT scan and assessed the correlation between the mental status at admission, the outcome and the CT findings. The location of hematoma volume of hematoma quadrigeminal cistern obliteration intraventricular hemorrhage and hydrocephalus were correlated to the mental status assessed by GCS at admission. The GCS score at admission. location of hematoma volume of hematoma quadrigeminal cistern obliteration intraventricular hemorrhage and hydrocephalus were correlated to the outcome. We conclude that decreased GCS score at admission, large volume of hematoma, quadrigeminal cistern obliteration presence of intraventricular hemorrhage and hydrocephalus could be considered as surgical indications and contributing factors for poor prognosis in the patients with spontaneous intracerebellar hemorrhage.

The magnetic polishing is the usefiil method to finish using magnetic power of magnet. This method is one of precision polishing techniques and has an aim of the clean technology using for the pure of gas and inside of the clean pipe for transportation. The magnetic abrasive polishing method is not so common for machine that it is not spreaded widely. There are rarely researcher in this field because of non-effectiveness of magnetic abrasive. Therefore, in this paper deals with development of the magnetic abrasive using sludge. In this development, abrasive grain WA and GC used to resin bond fabricated low temperature. And magnetic material was fabricated from the sludge which were crused into 200 mesh and average diameter 01.2mm ball type. The XRD analysis result show that only WA and GC abrasive and sludge crystal peaks detected which explains resin bond was not any more chemical reaction. From SEM analysis it is found that WA and GC abrasive and sludge were strong bonding with each other by bond.

Many formal description techniques have been developed to specify remote communication services which play a role of bridge in a highly developed information society. The transformation tools turn up to specify communication services more efficiently by connecting various formal description techniques. In this paper, we propose an EFSM (extended finite state machine), which is simple and easy to understand, instead of SDL/GR (specification and description language/graphical representation) which the more detailed, the less readable. We propose twelve transformation rules to transform EFSM into SDL/GR, a language-oriented model, and then we can increase productivity by using the automatic transformation tool executing twelve transformation rules.
