The purpose of the present investigation was to compare physique, skeletal maturation and physical fitness in Korean adolescents measured between 1998 and 2007. Subjects participated in the study were a total of 473 Korean adolescents aged 12 to 13 years. In 1998, 349 adolescents were selected from a middle school, located in Sungnam city and 124 middle school students aged 12-13, located in Yongin city were participated in 2007. All measurements were conducted by one of the reseachers (Jong-Kook Song) with two different group of investigators between 1998 and 2007. Anthropometric characteristics were body mass, body height, sitting height, circumferences taken at sites of upper arm, flexed upper arm, chest, waist, hip, thigh, and calf, bone breadth taken at the sites of humerus, and femur, skinfold thicknesses taken at the sites of triceps, subscapular, suprailiac, thigh and medial calf. Skeletal maturity was assessed by TW3 (Tanner et al., 2001). Maturity scores for Radius-Ulna-Short bones (RUS) and bone age were calculated. Physical fitness parameters included flamingo balance, sit and reach, grip strength, sit-ups, standing long jump, bent arm hang, 50m shuttle run and multi-stage shuttle run. All data were analyzed by SAS Enterprise 3.0. Means and standard deviations were calculated by descriptive statistics. Independent t-test was applied to compare dependent variables between measurements. The level of significance was set at p<0.05. Results of the study showed that male adolescents aged 12-13years in 2007 had significantly higher (p<0.0001) femur diameter than adolescents in 1998. Male adolescents in 2007 had higher (p<0.05) chest, waist and calf circumferences than those of adolescents in 1998. Although no difference were found for RUS and bone age in males adolescents between 1998 and 2007 female adolescents in 2007 were significantly delayed for their skeletal maturity level compared to female adolescents in 1998. For physical fitness parameters male adolescents aged 12 years in 2007 performed better for flamingo balance (p<0.01), and 50m shuttle run (p<0.05) than those of adolescents in 1998. However, stand long jump and bent arm hang were significantly decreased in male adolescents in 2007. Female adolescents aged 12-13 years in 2007 had significantly higher flamingo balance, but female adolescents aged 12 years in 2007 performed significantly less for standing long jump (p<0.0001), bent arm hang (p<0.001) and speed (p<0.05) than those of female adolescents in 1998. In conclusions this study suggest that chest circumference for both male and female adolescents in 2007 was significantly higher than those in 1998. Skeletal maturity for female adolescents in 2007 were significantly delayed compared to female adolescents in 1998. Further study is needed to evaluate consistent various.

Despite intensive investigation into paraquat toxicity, neither the final cytotoxic mechanism nor a clinically useful antidote has been discovered. The mechanism of paraquat cytotoxicity is also debatable, but it is generally accepted that a redox reaction occurs between reduced paraquat and molecular oxygen. The intracellular reduction of paraquat occurs by various enzymes, such as DT-diaphorase, xanthine oxidase and glutathione reductase. In present study, we investigated that the effects of allopurinol, a xanthine oxidase inhibitor, and dicumarol, a DT-diaphorase inhibitor, in paraquat-intoxicated rats. The survivals of paraquat-intoxicated rats were increased by allopurinol treatment compared to paraquat-treated control rats , but not effected by dicumarol treatment. The activity of xanthine oxidase in the liver of allopurinol-treated rats was decreased and DT-diaphorase activity in liver of dicumarol treated rats was also decreased compared to normal control rats. The contents of glutathione in liver of paraquat treated rats was decreased but in paraquat+allopurinol treated rats, the decrements of glutathione contents was reduced but in paraquat+dicumarol treated rats, liver glutathione level was not changed compared to paraquat-treated rats. These results suggest that paraquat toxicity maybe reduced by administration of allopurinol but dicumarol did not have such effects .

Experiments were performed on mice to investigate the effects of a polycycic aromatic hydrocatbon, 3-methylcholanthrene (MCA) on Arthus reaction, delayed-type hypersensitivity (DTH) and antibody production to sheep red blood cells (SRBC). Mice were sensitized iv with 0.1㎖ of 1% SRBC suspension were treated with a single ip injection of olive oil alone or with different doses of MCA in oil (0.5∼50㎎/㎏0 at various time before (-) or after (+) sensitization (day 0) and were challenged at 4 days after SRBC. Atrhus reaction was measured at 3 hours after challenge and other responses at 24 hours. Treatment with MCA inhibited Arthus reaction and DTH to SRBC, measured by footpad swelling reaction, and this immunosuppressing effect was dependent on the dose and time of MCA treatment in relation to SRBC sensitization. Humoral immune responses as measured by serum hemagglutinin-and hemolysin-titers to SRBC were significantly depressed when MCA was injected before or at the same time of sensitization. However, the response was slightly depressed when injected after SRBC. These result indicate that MCA suppress the function of the cells involved in immune responses.

Phenolic compounds are toxic and persistent material in the environment, and exhibit objectional tastes and odors. They are commonly found in wastes from the petroleum refining industry, coke-making industry, chemical plants and resin manufactures. The experimental treatment study of phenolic wastewater using immobilized system of Pleurotus cornucopiae and Lentinus edodes was performed under the conditions that the influent phenol concentration 1,000㎎/ℓ, hydraulic retention time 4hr ∼ `0hr, filling rate of immobilized pellets 10∼20%. The treatment system used in this study gives better performance with a shorter hydraulic retention time than the activated sludge process. In the operational condition of influent phenol concentration 1,000㎎/ℓ, 20% of filling rate with immobilized Pleurotus cornucopiae and Lentinus edodes, the national discharge limit of effluent("Na" zone, less than phenol 3㎎/ℓ) was satisfied with less than 10㎏-COD_cr/㎥·day.

Photoelectric property of polyvinylalcohol(PVA)-immobilized chloroplast electrode was studied under aerobic condition. When illuminated the chloroplast/PV A/Pt, photoelectric signals were generated from the electrodes under aerobic condition. There was a good relationships between photoelectric signal intensity and chlorophyll content or photosynthetic electron transport activity of the PVA-chloroplast films over the platinum. The signal induction patterns were different at various pH of the electrolyte. These results suggest a potential use of the immobilized chloroplast films for the biological photosensor.

Cd1_-xZn_xS films were grown by chemical bath deposition (CBD), which is a very attractive method for low-cost and large-area solar cells. To improve the electrical conductivity of Cd1_-xZn_xS films, thin indium films(10-40nm thickness) were evaporated on the surface of Cd1_-xZn_xS films. Experimental parpmeters such as indium film thickness, Zn mole fraction, and the annealing temperature in terms of structural and electrical properties of Cd1_-xZn_xS films were investigated. The diffusion process was carried out by heating the sample in air at 150-550℃ for 20 minute. X-ray diffraction patterns of Cd1_-xZn_xS films indicate that the minimum thickness and annealing temperature for the formation of an In2O3 surface layer, which act as a barrier preventing the outdiffusion of indium, are 20nm and 350℃, respectively. This layer allows indium diffusion into the Cd1_-xZn_xS films and results in an indium-doped Cd1_-xZn_xS films. As the indium film thickness is increased, the resistivity decreases and the lowest value(0.3Ω-㎝) is obtained for Cd1_-xZn_xS films annealed at 450℃ with 40nm of the thickness.

This study was carried out to identify the effects of seaweed extracts(GA14) on growth of two rice cultivars, Junambyo and Donganbyo. Seedling qualities of two cultivars were better in all items including heading dates at early stage treated at seedling plus 2-3 leaf stages than at single treatment of seedling. Ripening ratio of Junambyo in paddy field was increased 0.3% by seaweed extracts(GA14) treatment, but that of Donganbyo decreased 0.5%. 1,000 grain weight of Junambyo and Donanbyo by seaweed extracts(GA14) treatment was two to four grams higher and the yield of two cultivars was also higher by three to four percent. Appearance characters of two rice cultivars was high in head, while damaged, chalky and crack rate were low at seaweed extracts(GA14) treatment. Protein, moisture and amylose characteristics related to table quality of Junambyo were not different by seaweed extracts treatment, but table values was high in only treatment. Donganbyo was also similar to Junambyo, but table quality was slightly high at non-treatment.

Objectives : This study was conducted to evaluate the reliability and the validity of the Korean version of the Scale to Assessment Unawareness of Mental Disorder (SUMD-K). Methods : The subjects were 55 schizophrenic patients between ages of 26 and 58 who were recruited from the psychiatric unit of the university hospital and the out-patient clinic. The SUMD-K and insight scale of PANSS were applied to the patients. Results : The range of inter-rater (Spearman's rho) of the general items of SUMD-K were .97-.98 on the current illness and .58-.98 on the past illness. The correlation coefficient between the sum and the general items of the SUMD-K showed high scores. The concurrent validity between SUMD-K and insight item of PANSS was high (scores between .59-.96). However,the reliability and the validity of the attribution items of symptoms showed low scores compared to the current symptoms. Conclusion : The SUMD-K was confirmed in its reliability and validity. It can be a useful clinician-rating scale for evaluating insight in schizophrenic patients as well as patients with other neuropsychiatric conditions.

The g Ⅲ gene located in U_L region of Yangsan strain, a field isolate of Aujeszky's disease virus (ADV) in Korea, was cloned into pTZ18R and sequenced. The gⅢ gene consisting of 1,437 nucleotides showed 98% sequence homology with that of Becker strain, a reference strain of ADV. The gene encoding gⅢ of Yangsan strain was placed under the control of Autographa californica nucleopolyhedrosis virus (AcNPV) polyhedrin promoter, and expressed by the derived recombinant baculovirus using Spodoptera frugiperda 9 (Sf9) cells. The expressed gⅢ was a protein with molecular weight of 72kd determined by immunoprecipitation and Western blotting assay using anti-ADV polyclonal antibodies and anti-gⅢ monoclonal antibody. The partially purified gⅢ protein was utilized as antigen in the radial immunodiffusion enzyme assay (RIDEA) to detect to specific antibody against ADV in pig sera. The results indicated that the sensitivity of RIDEA with the recombinant gⅢ protein antigen (98%) was as high as that with the conventional glycoprotein antigen extracted from the ADV infected cells. In addition, the false positive and false nagative reactions in gⅢ RIDEA were significantly reduced than the conventional glycoprotein RIDEA as judged from the results of standard serum neutralization test.

In order to enumerate the T lymphocytes in bovine peripheral blood lymphocytes(PBL) by E rosette assay, KGRBC were treated with various concentration of 2-aminoethylisothiouronium bromide hydrobromide(AET) and dextran(Dex), singte or combination. The PBL from 10 clinically normal Korean native cattle were formed as low percentage of spontaneous E rosette(6.7±2.4%) in control group, whereas KGRBC treated with 0.1M AET for 20 minutes and 8%Dex were formed as 37.3±2.7% and 45.1±2.1%, respectively. And the synergistic effects were noted no less than 66.5±5.6% when the KGRBC treated with 0.1M AET and 8% Dex subsequently. These results suggest that the KGRBC would be a useful agent for the enumeration of T tymphocytes by E rosette assay in bovine PBI.
