권오용 (Oh Yong Kwon) 한국식물학회 1962 Journal of Plant Biology Vol.5 No.3

KWON, Oh Yong (Dept. of Botany, S. N. U.) Studies on the identification of Pleioblastus Simoni in Korean Bamboos. Kor. Jour. Bot. V(3): 5-10, 1962 Studies on the anatomical observation of Bamboos distributed in East-South Asia for systematic botany were sccrecely reported except for the morphological studies on Bamboos, which was investigated by Dr. Hiroshi Usui.^(3)4)) present author^(5)) and others. Recently it has been certain that it could be hardly classify some species of bamboo family without this work. For this reason the author reported the anatomical studies on Korean bamboos in 1959. and furthermore the author intended to identify the two species of Pletoblastus Simoni Nakai in Korean bamboos by studying the characteristics of internal structure and qualitative assay of free amino acid containg in Pleioblastus Simoni Nakai (1), (2). In view of fact that there is some diferences between two species, it is likely to be identifiable completely different species one another. Futhermore, a lot of characteristics surveyed by the author were as follow: It was reassumed that two species cultivated under same conditions for three years were different alternately in the species of Pleiblastus Simoni Nakai. At the same time, these studiecs could clarify some evolutional processes of bamboo familly. On the other hand, it was found that two species had not only the obvious difference in aerenchyma, the size of thitkwallecd parenchyma and bulliform cell, but also the internode of Pleloblastus Simoni Nakai(1) is longer than the other, the speed of growing is more rapid, the leaf of former is narrow and that of latter is wide. The free amino acids containg in each species were found as 18 kinds, especially Pleiobkastu ilmonl Nakai (2) had not Histidine in spite of containg in Pleioblastus Simoni Nakai (1). From the characteristics and the experiments described above, it seemed to the author that Pleiblasus Simoni Nakai(2), which was growing at the region of Pohang in Korea, was a variety of Pleioblastus Simoni Nakai (1) which was growing at the region of Ulsan in Korea.

When germination beds of carrot seeds were treated with either 0.01M or 0.05M concentrations of Ca(No_3)_2, CaSO_4, MgSO_4, K_2SO_4 and KH_2PO_4, an acceleraion in the germination rate was observed in the groups treated with 0.01M KH_2PO_4 and 0.05M MgSO_4, and 0.05M Ca(NO_2)_3. In earlier work by the author with acetone a similar result was observed and reported. The pH range in these experiments was maintained between 5.0 and 6.0. It was found that the groups treated with 0.05.M K_2SO_4, 0.05M Ca(NO_3)_2, 0.05M MgSO_4, 0.01M KH_2PO_4, 0.01M Ca(NO_3)_2 germinated earlier than the control group. The acceleration of the germination rate varied with the inorganic compounds used in the following descending order; 0.01M KH_2PO_4, 0.05M Ca(NO_3)_2, 0.05M K_2SO_4, 0.05M CaSO_4 and 0.05M KH_2PO_4. As a result of these expriments, it occurs to the author that in the germination of carrot seeds some inorganic compounds appear to activate the osmotic function of carrot seeds causing acceleration in the germination rate.

The treatment of X-ray was manipulated with the large focus of X-ray which was produced the capacity of 90 kilovoltage and 30 milliamphere in the distance of 50 centimeter. The germination of each group irradiated with X-ray for 5, 6, and 7 seconds was more delayed in the growth of carrot seed than those of the control group. However the germination of each group irradiated with X-ray for 2,3, and 4 seconds was rather accelerated than those of the control group. The irradiation of ultraviolet light was carried out in the distance of 20 centimeter by Toshiba germidicial lamp which appeared the wavelength of 2537 A˚. The germination of each group irradiated with ultraviolet light for 9, 15, 20, and 40 minutes was more delayed than those of the control group, but the germination of carrot seed was accelerated by adequate dosage of ultraviolet light. Consuquently it was suggested for the author that the inhibited substance contained in carrot seed would be certain fatty substance, because the germination of carrot seed was more accelerated by the treatment of acetone than those of X-ray and ultraviolet light.

종자발아에 있어서 Protein Profile 과 Isozyme 에 관한 연구

권오용 (Oh Yong Kwon) 한국식물학회 1974 Journal of Plant Biology Vol.17 No.4

The purpose of this experiment was to study one side of germination physiology based on that protein profiles and pretease relating to protein metabolism, that peroxidase, catalase, α-amylase, β-amylase, and malate dehydrogenase involved in the carbohydrate metabolism of seed germination. All these experiments were divided into the two groups with and without acetone treatment, and were carried out. The protein bands of each germinating stage between the groups treated with and without acetone showed certain basic pattern in polyacrylamide gel disc electrophoresis. However, there was a little difference in the number of protein band, optical density, and migration velocity between two eroups. The isozyme bands of peroxidase, and catalase between two groups in polyacrylamide get disc electrophoresis did not show the numeral difference, but the optical density of certain germinating stage treated with acetone was higher than the group untreated with it and it showed their enzyme activity. The α-amylase and β-amylase activities which involved in starch metabolism of seed germination were higher in the treated group than the other. On one hand, the protease activity of hydrolase occurred in the seeds for germination was also higher, more or less in the treated group than in the other. The isozyme band pattern of malate dehydrogenase in TCA cycle of energy metabolism pathway was very different between two groups growing for 72 hours with and without acetone treatment in cellulose acetate electrophoresis. It indicated that two isozyme bands of malate dehydrogenase was high. Consequently these experimental results mentioned above indicated that acetone treatment before sowing had an effect on dissolving certain complexed lipid substance involved in the seed coats, the activity of carbohydrate hydrolase increased with water absorption which was most comfortable in its germination, dissolved glycerin and fatty acid became certain energy source, and they stimulated the acceleration of respiration metabolism.

KWON, Oh Yong (Chunju Teacher`s coll.) Pattern of the acids influenced on nitrogen metabolism of edible bamboo sprouts. Kor. Jour. Bot. Ⅵ (4):5-10, 1963. It had been scarcely reported by any worker that the essential amino acids to be indispensable in our daily life contained in edible bamboo sprouts and that they had various pattern of free amino acids. For this reason, especially two speries of Korean bamboo sprouts collected from the surburb of Chunju, in April, 1963 were used for researching the essential amino acids and free amino acids sppeared on paper chromatography. The most suitable part for our edibles was investigated as a part of bio-chemical studies on Korean bamboo sprouts. The free amino acids contained in two species were found as 5-15 kinds and there were a few of difference according to it`s growing parts. Many kinds of free amino acids were found in the end parts more than the tip parts and mid parts of bamboo sprouta. Besides, the essential amino acids in each species were found to 3-9 kinds. From the characteristics and the experiments marked above, it was suggested to the author that many kinds of free amino acids in the end part accelerated the formation of nitrogen compounds more than the other parts.

The statistics of recent accidents in warehouses show that a heavy toll of lives were produced by various accidents, e.g. collision,overturn, fall, slip, exposure to harmful substances or environments, etc. Of significant concern amongst them is the collision, especially the collision between forklift and storage rack structure. Accordingly, this study focuses on behavioral characteristics of rack structure subjected to dynamic impact loading of a forklift. For this purpose, time-domain response analysis has been performed on a standard 2-bay six-story rack structure consisting of columns, beams and bracing members with perforated open section. In order to investigate the most critical scenario, the impact loads are applied in both down-aisle and cross-aisle directions, and the impact locations are also varied along the shelves of the palettes. In order to deal with storage distributions, three types of rack structures are further taken into account: original empty rack structure with no storage, half-loaded rack structure and fully-loaded rack structure. The numerical simulation results demonstrate that the dynamic characteristics of the rack structure are significantly dependent on the distribution of the storage goods and its natural period varies from 0.24sec to 1.06sec, approximately 4.4 times. Further, the parametric studies show that the forklift impact is most critical to the safety of the rack structure when it collides either at the base or at the top of the rack structure.

Lee, Min Jai (Dept. of Botany, Seoul National Univ.) and Kwon, Oh Yong (Andong Teacher`s College) Effects of neutron radiation on the metabolism of Saccharomyces cerevisiae. Kor. Jour. Bot. Ⅶ(4) : 9-14. 1964. According to the results measured the respiratory quotient of Saccharomyces cerevisiae with neutron radiation by manometric direct method, the respiratory quotient of them was stimulated at the dose (7×10 exp (6) N/㎠/sec) of neutron radiation for 60 seconds, and was inhibited in each group irraaiated at the high dose (7×10 exp (3)N/㎠/sec) of neutron. Its physioiogical effects influenced on neutron had relations with respiratory quotient, reproductive rate and fermentation in the curve of normal logarithmic phase. The multiple reartions which appeared in yeast, indicated that a great deal of physiological function were closely correlated with the irradiated dosage of neutron. The kinds of free amino acid in yeast irradiated with neutron were different from those of unirradiated yeast. The activity of dehydrogenase system accelerated the metabolic function of yeast irradiated at some low dose of neutron. By this results, it may demonstrate that the fact which the phenomena obtained in the stimulation of neutron possess its character for several generation, is dependent on the theory of mutation. Subsequently, it seemed reasonable certain dominant type of microorganisms.
