In this study, we examined the ultrastructural influence of radiation on rats stomach tissue, the difference between NPO and con in the rats stomach was measured after a single irradiation to 15 Gy dose, the results follow ; Widening of intercellular space, and swelling and degeneration of secretory granules in chief cells were observed from NPO rats of a day after irradiation. In mucosal epithelial cells of con rats of 7 days after irradiation, destruction of microvilli was similar to from NPO rats of a day after irradiation but morphology was cuboidal. Parietal cell proliferation and differentiation were active as well as mucous epithelia structures were stable like to control rats from con of 14 days after irradiation. But NPO rats were not until 28 days after irradiation that mucous epithelial structures were stable too. On the basis of this results, we know obviously that NPO will be a factor of stomach abnomalities while hospital patients are treated with high-energy irradiation.

본 연구는 널리 알려져 있으면서도 한편으로는 제대로 인식되지 않은 삶의 한 가지 방식으로서 구조주의적 가정의 관점으로 현재 유아교육현장에서 발생하는 언어현상의 문제들을 해석해 보고 이러한 문제들에 대한 개선방안을 구조주의의 한계를 비판하면서 출현한 후기구조주의적 접근을 통해 논의해 보았다. 연구의 결과 구조주의적인 관점에서 유아 교실의 언어현상은 초월적 기의의 존재, 개체의 존엄과 본질의 외면, 언어와 사고의 경직성이라는 문제점을 가지고 있었고 이에 대한 후기구조주의적 관점에서의 해결 방향은 초월적 기의의 해체, 개체와 본질의 존엄성 찾아가기, 언어의 시적 기능 회복하기라는 세 가지로 제시되었다. The purpose of this study expolres the language phenomena of early childhood classroom from Post-Structualistic perspectives. In order to achieve this purpose, the characteristics of language to generate in early childhood classroom was firstly discussed from structualistic perspectives. The result was that currently language to generate in early childhood classroom is very structualistic and can't reflect children's real life context. Therefore, In this study, to solve the ploblems of currently language to generate in early childhood classroom, researcher suggest that from post-structualistic perspectives the language to generate in early childhood classroom should be rethinked. On post-structualistic perspectives the early children's language should be reflect children's real life context and recover poetic function of language.

Washed rice was coated by spraying aqueous dandelion (Taraxacum officinale) extracts at 20, 30, 40 'Brix and dried at room temperature. The coating procedure was conducted 5 mL/min for 10min. Property changes in the dandelion coated rice and un-coated cooked rice were observed during 2 days of storage. Increasing the coating concentration was associated with lower color values (L, a value) and moisture contents. Sensory and texture properties generally decreased in the cooked rice coated with dandelion more than the control (non-coated rice). But, D-20(20 °Brix of the dandelion concentration) resulted in better textural properties and s ensnry scores for hardness and overall acceptability in cooked rice. Compared to the control, the washed rice roated with 20 °Brix for 0 and 2 days showed better quality in sensory activities, a lower gel consistency and better textural activities. It was concluded that the optimum coating ration of rice and added dandelion extract for cooking were 20 °Brix and 5% respectively, in proportion to the total weight of raw rice.

電子빔勵起 KrF레이저의 出力特性에 대한 시뮤레이숀 解析

李柱熙,崔富淵 慶熙大學校 1985 論文集 Vol.14 No.-

By developing a comprehensive computer simulation code for e-beam excited KrF lasers, we studied mainly the effect of output performance dependence on excitation rate excited by an intense electron beam. Especially for short pulse (<50 ns) and high excitation rate pumping (>2Mw/㎤), and under realizable conditions, it is found to calculated with an intrinsic laser effieiency as a function of excitation rate. The results were compared with some experimental results, and a fairly good agreement was obtained. At an excitation rate of 7 Mw/㎤, and at a total gas pressure of 2 atm, an intrinsic efficiency of up to 10.5% is found to be attainable. We have also calculated the KrF^* production efficiency and the laser extraction efficiency, and explained the output performance in terms of excitation rate.

李柱熙,崔富淵,全商永,鄭在根 慶熙大學校 1989 論文集 Vol.18 No.-

We have developed a KrF excimer laser system with UV preionized charge transfer type and an analysis program of discharge characteristics which oilers calculations of the deposited energy, nonlinear discharge resistance, and electron number density in the laser tube. In addition, we have developed a pulse compression system with MPC type for excitation of excimer laser. From this system, we obtained a maximum output energy of 80 mJ, laser pulse width of 40 ns [FWHM], and overall efficiency of 0.32%. Calculating with analysis program, deposited energy, nonlinear discharge resistance, and electron number density were found to be 200 MW, ∞∼0.17Ω, 1×10 exp (16) ㎝^(-3), respectively. The saturable inductor of pulse compression system made of Metglas 2605 S-2 and Z-11, and the compression characteristics of saturable inductors are compared. With this system, 6.2 us [FWHM], 96 A pulse at the first stage was compressed to 0,4 us [FWHM], 1.61kA pulse at the last stage, and hence the current gain and compression ratio were 16.8 and 17, respectively.

Various kinds of the industrial wastes, when introduced into the environment, can cause many problems, Proper treatment and utilization of the wastes thus are one of the recent environmental concerns. A greenhouse experiment was conducted to investigate the influence of organic sludge from the beer manufacturing process on the growth of the Korean turf (Zoysia japonica, STEUD.) and the chemical properties of the soil. Treatment levels of the experimental organic sludge, which was pre-treated with quicklime, were ranged fom 0 to 20kg/m³. Sowing dates were 5 to 30 days elapsed after the sludge application. Increasing levels of the experimental sludge increased height, root length, number of leaf, and yields of the turf. Planting periods interacted with treatment level of the sludge to show a positive effect on the growth parameters. Uptakes of nitrogen and calcium were also enhanced by treatment. Soil organic matter and exchangeable Ca contents were increased by the sludge treatment. Sludge caused to increase soil pH upto 8.3 and this maintained for over 60 days. A possibility to utilize this organic sludge as a fertilizer could be supported by results of positive effects of this sludge on growth, nutrient uptake and soil fertility parameters, Further researches on the utilization of the industrial wastes, concerning on treatment level, long term effect, and a possible side effect, should be followed.

Background : To exatnine the problems intolved in writing practice of death certificates, we cotnpated the determination of underlying cause of death for wital statistics using recorded underlying cause of death in issued death statistics. Methods : We collected 688 rnortality certificates issue in year of 2,000 from 3 university hospitals. And we also collected vital statistics from ministry of statistics. The causes of death were coded by experienced medical record wpecialists. And causes of death determined at ministry of statistics for national vita statistics were mapped to causes of death recorded at each death certificates. The rate that underlying causes of death for vital statistics were derived from underlying causes of death recorded at issued death certificaties sere analysed. Results : 64.5% of underlying cause of death for could be derived from underlying cause of death recorded at issued death certificates, 8.6% derived from intermediate cause of death, and 3.9% derived from direct cause of death. In 23% of cases, underlying cause of death could not be derived using issued death certificates. The rate that underlying cause of death for vital statistics could be derived from underlying cause of death recorded at death certificates was different between 3 university hospitals. Ane the rate was also different between death certificates and postmortem certificates. We classified the causes of death using 21 major categories. The rate was different between diseases or conditions tha caused death too. Conclusion : When we examined the correctness of death certificate writing practice using abpve methods, cortectness of writing could not be told as satisfactory. There was difference in correctness of writing between hospotals, between death certificates and postmortem certificates, and between diseases and conditions that caused death. With this results, we suggested some strategy to improve the correctness of death certificate writing practice.

Phylogeny and distribution of the genus<i>Pikea</i>(Gigartinales, Rhodophyta) with special reference to<i>P. yoshizakii</i>from Korea

Boo, Ga Hun,Hwang, Il Ki,Ha, Dong Su,Miller, Kathy Ann,Kogame, Kazuhiro,Cho, Ga Youn,Kim, Jung Yeon,Boo, Sung Min Informa UK (TaylorFrancis) 2016 Phycologia Vol.55 No.1

<P>Four species have been described in the genus Pikea (Dumontiaceae, Gigartinales): three species from North America and one species from Japan. However, the phylogeny and species delimitation in Pikea remain poorly resolved. Here we provide both rbcL and cox1 sequences for all species of Pikea, including the type of P. pinnata and a paratype of P. robusta. Our data reveal that P. californica, P. pinnata and P. yoshizakii are distinct in both data sets, but P. robusta is synonymous with the earlier-described P. pinnata. Morphological and molecular data show that Pikea from Korea is identical to P. yoshizakii and that the previous report of P. californica in Korea is a misidentification. The genus Pikea is well resolved in the main clade of the Dumontiaceae. This is the first study on the phylogeny of Pikea using rbcL and cox1 sequence data.</P>
