The freshwater fish fauna of Yongsan River stream and the change of fish fauna in Yongsan Lake were investigated from October, 1987, to August, 1988. total collected fishes were 20 families, 44 genera, 64 species and subspecies, 17,728 individuals including 31 species of Cyprinidae, 7 species of Gobiidae, 4 species of Cobitidae and 3 species of Bagridae, and among them 15 species were known as Korean endemic species. Squalidus chankaensis tsuchigae, Liobagrus obesus, Oncorhynchus masou, Hemiramphus kurumens, Gasteroteus aculeatus, Mugil cephalus, M. haematocheila, Rhinogobius giurinus, Acanthogobius flavimanus, A. hasta, Chaenogobius annularis, Tridentiger obscurus were observed in the present studied areas for the first time. In Yongsan River system and the total number of species including primary freshwater fishes and peripheral fishes increased as the water quality of Yongsan Lake changed into feshwater.

Allylphenyl ether의 합성 및 oxymercuration-demercuration 반응

권태우,김재곤 慶星大學校 1996 論文集 Vol.17 No.2

Treatments of 2,4,6-trimethylphenol with allyl bromide, 4-bromo-2-methyl-2-butene in K₂CO₃/acetone lead to the corresponding allyl phenyl ether derivatives. Two allylphenyl ethers were compared with their splitting patterns in the HNMR spectrum. Additionally, allyl phenyl ether, 3, can react with Hg(OAc)₂/NaBH₄/NaOH(aq) to give the oxymercuration-demercuration product, 5 in good yield.

宋泰坤,李完玉,朴炅洋 木浦大學校基礎科學硏究所 1988 基礎科學硏究誌 Vol.6 No.-

The freshwater fish fauna was investigated from April, 1987 to August, 1988 in Watan chon, Pulgap chon, Ch'ong chon and Ch'onggye chon of Chol-lanamdo. The collected fish were 6 families, 19 genera, 22 species in Watan chon 9 families, 20 genera, 25 species in Pulgap chon, 7 families, 17 genera, 17 species in Ch'ong chon and 7 families, 13 genera, 15 species in Ch'onggye chon. It was remarkable point in the distributional study of freshwater fishes of Korea that two individuals of Cobitis koreensis were collected in Pulgap chon for the first time and the morphology of them was very similar to the Tongjin River population. This indicated that Pulgap chon was found to be the southern limit of distribution of C. koreensis koreensis. Growth rate and age composition were analyzed by total length of 6 species such as Squalidus gracilis majimae, Abbottina springeri, A. rivularis, Moroco oxycephalus, Cobitis lutheri and Zacco temmincki.

Total fishes collected from them were 9 families, 18 genera, 20 species, 1,992 individuals. Among them, 20 species were Cyprinidae, and 2 species were known as Korean endemic species. In this investigation, the abundant species were Pseudorasbora parva, Oryzias latipes, Zacco platypus, Hemicultur eigenmanni, and Zacco temmincki. The taxa of benthic invertebrates was composed of 42 species, 34 genera, 27 families,13 orders, 7 classes in 4 phyla. Among them, aquatic insects containing 20 species were the major group. On comparing individual numbers in this survey, Mollusca were the highest(60.7%), and Annelida and Diptera were 13.0% and 11.0%, respectively.

한국산 족부 백선균의 항진균제 감수성에 관한 연구

김승곤,김태전,이태수 서울保健大學 1997 論文集 Vol.17 No.1

Minimum inhibitory concentration(MIC) of griseofulvin, imidazole derivatives such as ketoconazole, econazole, miconazole and itraconazole on 52 strains of Trichophyton ruhrum, 22 strains of T. mentagraphytes, 10 strains of Microsporum spp. and 1 strain of Epidermophyton floccosum were determined after one week of incubation at 25C on Sabouraud dextrose broth. The results were summarized as followes : 1. The MICs of griseofulvin against 4 different tinea pedis fungi were ranged from 10-100mcg/ml. This values indicated that effectiveness of antifungal activity were relatively lower than those of three other imidazole derivatives such as ketoconazole, econazole, miconazole and one itraconazole. 2. Out of three imidazole derivatives, econazole had relatively higher inhibitory concentrations with 0.1-10mcg/ml against all tinea pedis isolated. 3. Out of 5 antifungal agents, itraconazole which is trizole derivatives showed the highest inhibitory activity with 0.1-10mcg/ml against all tinea pedis tested. 4. These results indicated that inhibitory activity of griseofulvin against tinea pedis were lower than those of four other antifungal agents tested. But these four antifungal agents such as ketoconazole, econazole, miconazole and. itraconazole were effective against tinea pedis tested.

Guinea pig 단일 심실근 세포의 칼슘전류에 대한 아드레날린성 약물의 효과

백승곤,심태섭,방효원 중앙대학교 의과대학 의과학연구소 1991 中央醫大誌 Vol.16 No.4

In order to investigate the effects of sympathomimetic drugs on the calcium currents, whole cell patch clamp technique was used in ventricular cells of the guinea-pig. Single ventricular cells were isolated by Langedorff perfusion method with collagenase. T-type and L-type Ca-currents were recorded in different holding potentials. T-type Ca-current was activated from more negative membrane potentials(around -50 mV) and was inactivated very rapidly, whereas L-type Ca-current was activated from -30 mV and inactivated with two time constants(fast and slow components). Replacement of calcium with barium increased the activation magnitude of L-type Ca-current and delayed inactivation time course, but did not affect T-type Ca-current significantly. Nifedipine blocked and Bay K 8644 increased L-type Ca-current with voltage-dependent manner. T-type Ca-current, however, was relatively insentive to dihydropyridine compuonds. Isoproterenol which is known to have mainly beta-agonist increased L-and T-type Ca-currents and propranolol reversed the effect of isoproterenol. Phenylephrine(alpha-agonist) and phentolamine(alpha-blocker) have no significant effects on the Ca-currents. From the above results it is suggested that L-type and T-type Ca-currents are present in guineapig ventricular myocytes and very sensitive to beta-agonist or-antagonist, but relatively insensitive to drugs acting on alpha-receptors.

特定産業 支援政策이 生産要素 投入과 生産性에 미치는 영향에 관한 硏究 : 한국의 중화학공업 육성정책을 중심으로

신태곤 釜山大學校 商科大學 1993 釜山商大論集 Vol.64 No.-

The industrial policy can be divided into two categories ; the general policy and the industry specific policy. The former deals with the traditional macroeconomic policies such as the fiscal and monetary policies, anti-trust issues, and the international trade policies. Recently, the industry specific policies, once disregarded by the main stream economics but favored by the practioners for a long time, become a main issue in the academic community, especially, in the U. S. A. While Japan, Korea, Taiwan and other NIEs in Asia, which armed with the industry specific policies, have been enjoying the rapid economic growth for many years, the advanced countries, especially, the United States went through the slow productivity growth, the huge trade deficits, and the loss of competitiveness in the last two decades. The made the U. S. policy makers and academic community reevaluate the effectiveness of the active industrial policies. This paper studied the issue of the effectiveness of a finance cum tax subsidize industry specific policies. We provide a theoretical ground that the above-mentioned policy can lead an excessive capital consumption and the deterioration of the total factor productivity. This theory was empirically tested to the heavy and chemical industry support programs for 1973-79 in Korea. We found that the industry specific policy speeded up the targeted industries' capital growth and lowered the total factor productivity growth relative to those of the unsupported industries. We also found that the anomaly disappeared when the subsidization completely stopped in 1984. Policy implications are evident that finance cum tax subsidized industry specific policies should be accompanies with other measures which can improve the total factor productivity such programs that enhance capital quality and or labor quality enhancing program.
