Preventive and Antioxidative Effects of Crude Drug Preparation(E-kong-san) on Cisplatin Induced Nephrotoxicity. Proceedings of International Symposium on East-West Medicine, Seoul. 201-211, 1999. -Nephroprotective effects of a crude drug-prearation (E-kong-san) were determined from cisplatin on rabbit kidney proximal tubule and human renal cortical cells by MTT assays and sustained glucose consumption on ciplatin-induced human renal cortical tissue. Levels of creatinine and blood ure nitrogen(BUN) in serum after administration of cisplatin(0.75mg/kg,i.p.) to E-kong-san(0.75g/kg/day,p.o.)-pretreated rats were markedly lower compared to those of cisplatin-treated rats. Moreover, the administration of E-kong-san significantly inhibited the loss of body weight of cisplatin injected rts. These findings suggest that E-kong-san on the cisplatin induced nephrotoxicity led us to investigate whether the effect of this water extract was a result of anti-oxidation. E-kong-san showed strong free radical scavenger activities on 1,1-dipheny1-2picrylhydrazil(DPPH) radical and xanthine/xanthine oxidase(XOD) generated superoxide anion radical(O2-). We further studied the effects of E-kong-san on lipid peroxidation in rat liver microsomes induced by enzymatic and nonenzymatic methods. E-kong-san exhibited significant inhibition on both ascorbic acid/Fe2+and ADP/NADPH/Fe3+ induced lipid peroxidation in rat liver microsomes. Based on these results, we suggest that-E-kong-san attenuate the cisplatin induced cytotoxicity and its mechanism can be eplained by antioxidant.

Analysis of Insulation Diagnosis for Generator‑Motor Stator Winding in Pumped Storage Power Plant

Soo‑Hoh Lee,Tae‑Sik Kong,Hee‑Dong Kim 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.3

In this study, insulation diagnostic tests were conducted on pumped storage power plant (PSPP) generator-motor stator bars with artifcially simulated defects in order to improve solutions to perform preventive maintenance and track insulation diagnostic data for generator-motors by proving the efectiveness of insulation indices. Moreover, ozone (O3) concentration was estimated in order to relate it to partial discharge (PD) in laboratory to ensure the efectiveness of ozone as another index for insulation deterioration. By performing an ofine PD test and ultraviolet (UV) observation on one of the generator-motors during overhaul, and an ozone concentration measurement for the identical machine after the overhaul, it was concluded that ozone estimation could be a powerful index for insulation diagnosis under actual operational conditions. It was further developed that ozone measurement is useful to detect not only discharges in slots as mentioned in some studies but also discharges at the end-winding as proven in this study. The fndings of this study are expected to contribute to more reliable maintenance of generator-motors in PSPPs by achieving elaborate insulation diagnosis via multiple diagnostic indices.

Voltage transformers (VTs) must be highly reliable as they are essential components of the electric power industry. VT failures can cause a signifcant impact for important facilities such as nuclear power plants. In fact, VTs which passed the international standard, were damaged and sometimes resulted in the shutdown of the nuclear power plants. In order to improve the reliability, VTs with various iron core was studied. The electromagnetic feld simulation, a saturation characteristics test, and an overvoltage breakdown test were conducted. The result shows that the magnetic fux density signifcantly afects the reliability of VTs. To increase the reliability of VTs, it is required to reduce the magnetic fux density by increasing the knee-point and voltage factor. Owing to limited installation space, increasing the size of the iron core is difcult. Instead, VT by decreasing the thickness of the conductor and increasing the number of turns, it was possible to reduce the magnetic fux density without the size change. Therefore, improved VTs were obtained by decreasing the thickness of the conductor and increasing the number of turns, and the improved reliability was verifed through a comparison test with existing VTs. The fabricated VTs shows a signifcantly higher saturation voltage and breakdown time than existing VTs. Thus, by proposed VTs can contribute the stable operation of the nuclear power plant and improve the manufacturer’s quality.

Models in species abundance distribution in presenting community states and environmental impact

Tae‐Soo Chon 한국응용곤충학회 2008 한국응용곤충학회 학술대회논문집 Vol.2008 No.05

Species abundance patterns have been recently one of key issues in ecology regarding determination of the allowable species richness in a determined area (i.e., island biogeography) and elucidation of structural coherence residing in the relationships between species and their corresponding abundance in communities. The topic of relative species abundance or species abundance distribution (SAD) is considered significant in revealing origination of community establishment in theoretical aspect and in presenting ecological states in response to environmental impact in practical aspect. Conventional models used in SADs including geometric series, log series, log normal distribution and broken stick model were introduced along with example cases. Theoretical interpretation of species abundance patterns was additionally outlined covering the neutral model, power law analysis and application of principles in statistical physics. The future of SADs and the species‐abundance related topics was discussed regarding community organization mechanism and ecological monitoring in response to disturbances.

『三國遺事』 효자승전승에 나타난 불교적 효윤리

신태수(Shin, Tae-soo) 한국어문학회 2016 語文學 Vol.0 No.131

When Buddhist monks that perform filial piety are called Buddhist monks of filial piety, the traditions in which Buddhist monks of filial piety appear can be called traditions of Buddhist monks of filial piety. Since all the traditions of Buddhist monks of filial piety present protagonists that were from a lower class and broken home and underwent psychological conflicts with regard to remarriage and entry into Buddhist priesthood, those common features can be regarded as requirements of traditions of Buddhist monks of filial piety. If there are psychological conflicts in the protagonists, there must be close connections between the system of filial piety ethics and their psychological conflicts. It is needed to figure out the composition of filial piety ethics to understand its system. There are two major compositions of filial piety ethics, namely “Jieun-Boeun” and “Odo-Dosaneg,” and the combination of the two compositions leads to the formation of “Hyoseonssangmi” system, in which psychological conflicts are not obstacles to the composition but rather hold a significant part in Buddhist ethics of filial piety. There are Confucian, shamanistic, and Taoist elements in Buddhist ethics of filial piety. It is estimated that Ilyeon must have introduced many different religious elements based on the “universalism-based ideological tolerance” and advocated “Buddhist ethics of filial piety in the system of Hyoseonssangmi.”

The perpose of this paper is examine the incremental information contents of non-accounting information in predicting business failure. Also, This paper investigates inter-industry differences in the predictors of bankruptcy. We analyzed listed firms which were included in the database developed by Korea Information Service(KIS). We estimated the bankruptcy prediction model for the period 1981~1997 using the data of one-years, two-years and three-years before the year of bankruptcy. The major results of this paper can be summarized as follows : First, non-accounting information variables were not useful in predicting the bankruptcy over and above the information contained in financial statements. Second, because there are inter-industry differences in the predictors of bankruptcy. the different predictors need to be used in estimating the bankruptcy prediction model in different industries.

Case Variations in Korean Periphrastic Causative Constructions

Sung, Tae soo 대한언어학회 1999 언어학 Vol.7 No.1

Sung, Tae-Soo. 1999 Case Variations in Korean Periphrastic Causative Constructions. Linguistics, 7-1, 1-31. The case variation of the causee in Korean is argued to be examined under the assumptions of the pragmatic correlations between causer and causes. In some causative situations, the causer affects its causee very strongly: in others, the influence of the causer over its causee is weak, relatively. However, despite this kind of difference, we argue that 1) causative sentences share the same underlying structure whether they involve a NOM causee, a DAT causee, or an ACC causee (case-marked as '-ka', '-eke', or '-lul', respectively); 2) why the causee of Korean periphrastic causative constructions alternates with '-ka', '-eke', and '-lul' is that the seemingly structural cases play a role of delimiters. Among '-ka', '-eke', and '-lul', the latter two are regarded as delimiters. In this article, it is argued that the case-doubling in Korean periphrastic causative construction appears only as a side-effect in uttering a causative construction under a apecific situation.
