  • 40 specimens of higher fungi were collected at the bamboo forest of Damyang, Jyunranam-Do, and Kyungju, Kyungsangnam-Do during May 6, August 17, 29 and October 29, 1976. These fungi were identified. They were composed of 3 orders, 10 families, 19 geaera and 23 species. Among them, Clitocybe catancifloccosa S. Ito et Imal, Collybia matris S. Ito et Imal, Mcrasiellus lactea (Pers. ex Fr.), Lepiota hetieri Boud. and Paxillus atrotomentosus (Fr.) Fr. var. bambusinus Baker et Dale were found to be new in Korea.

  • A new ternary strontium germanium nitride, ${\beta}-Sr_2GeN_2$, was obtained as single crystal from constituent elements in molten Na. It crystallizes in space group Cmca (No. 64) with a = 5.441(1) $\AA$, b = 11.377(2) $\AA$, c = 12.229(2) $\AA$, and Z = 8. Its crystal structure is closely related to that of polymorphic companion, ${\alpha}-Sr_2GeN_2$, both of which contain isolated bent anions of ${GeN_2}^{4-}$.

  • Glutamine production from glutamate was carried out using glutamine synthetase from E. coli K-12 pgln 6 and baker's yeast, which supplies ATP into the reaction system through alcohol fermentation, simultaneously. With whole cells of E. coli K-12 pgln 6 as an enzyme source of glutamine synthetase, 11.8 g/ι of glutamine produced after 18-h incubation (60% yield based on a substrate, glutamate). Using the partially purified glutamine synthetase, 19.8 git of glutamine was produced after 5-h incubation. This amount of glutamine was correspond to 90% yield, based on substrate, glutamate.

  • In a study of the aerobic growth of Baker's yeast (Saccharomyces cerevisiae) on Maxon-Johnson medium (with glucose as substrate) solidified with kudzu root starch, it was observed that between 8 and 24 hour incubation. 10 and 12% solids stimulated greater cell production than did 6 and 8% solids. The concentration of solids also affected thd secretion of protein from the yeast cells with the highest content of extracellular protein at 10-24 hour incubation stimulated by 10% starch solids.

  • One of the most defining characteristics of arbitration is that an arbitral tribunal's jurisdiction is established by parties' mutual agreement. If a party to the arbitral proceedings believes that a tribunal constituted lacks jurisdiction to conduct the arbitral proceedings, it may challenge the jurisdiction of the tribunal in different ways. Although the concept of kompetenz-kompetenz and the grounds to challenge the Tribunal's jurisdiction are readily accepted in the arbitration community, what parties often fail to observe is the time limit imposed by the relevant laws in bringing such objections. This article aims to examine several main ways of challenging the tribunal's jurisdiction and the applicable time limits in each scenario. The article will then focus on the consequences of a party's failure to adhere to the strict time limits and its effect at the post-award stage. These issues will be considered in the light of case law from different Model law jurisdictions with particular illustrations from the arbitration law of Singapore.

  • Automatic counting of yeast cells in baker's yeast culture was tried using a conventional light microscope equipped with a pc camera. Relatively good binary image was obtained by using white LED as microscope light source, but uneven brightness distribution in original image hindered counting accuracy. A block binarization method using local thresholds proportional to local brightnesses was used to get improved binary images. The brightnesses of the blocks were expressed as the value component in HSV color model. Good quality binary images were obtained by binarization on $8{\times}6$ blocks of original images and connected-component labelling of the binarized images produced reliable counting results in the concentration range $1.4{\times}10^5/mL{\sim}1.4{\times}10^7\;cells/mL$.

  • Empirical equations for the oxide thickness and the weight gain of Zircaloy-4 cladding during the oxidation in high temperature, high pressure steam have been developed. Firstly, the empirical equations for oxide thickness in 1 atm steam in 700~100$0^{\circ}C$ were made, then, the enhancement factor for the steam pressure effects on Zircaloy-4 cladding oxidation in high temperature steam was added. Based on the analysis of the weight fraction of dissolved oxygen in metal layer, empirical equations for the weight gain of Zircaloy-4 in high pressure, high temperature steam were developed. We compare the developed empirical equations with the Baker-Just correlation. The Baker-Just correlation can give a non-conservative estimation of oxidation of Zircaloy-4, depending on the steam pressure. These developed empirical equations can be used for the correct estimation of oxidation of Zircaloy-4 during accident analysis.

  • In General, popliteal cyst found in children does not present a symptom and also it rarely causes a complication. The researcher observed an entrapment of tibial nerve and popliteal artery in a child with popliteal cyst without intra-articular lesion, and treated it by using early decompression and prolotherapy, which is presented in this study with literature review.

  • Six species of false spider mites were collected and ciassifled in South Korea. Among them, a taxonomic description was carried out on the following four species new to Korea: 1. Aegyptobia nothus Pritchard and Baker, 2. Pentomerismus taxi (Hailer), 3. P. oregonensis McGregor, 4. Brevipalpus lewisi McGregor. And also esterase and alkaline phosphatase patterns obtained by polyacrylamide slab gel electrophoresis were compared on some spades. Esterase rymogram showed difference among species in band number and mobility.
