The purpose of this study was to evaluate the health condition and nutritional status in female university students in Masan. The 285 subjects aged 20.1 years (18~26 years) were assessed with a set of questionnaire composed of general information, food, smoking, drinking and exercise habits, anthropometric measurements, blood pressure measurements, 24-hour recall and food frequency questionnaire. The rates of smoking and alcohol drinking habits were 1.8% and 82.5%, respectively. All the subjects had the experience of passive smoking. The 11% of the students exercised regularly and 11.6% ate meal regularly. The average height and weight of subjects were 161.0 ㎝ and 53.9 ㎏, respectively and the BMI was calculated as 20.8${\pm}$2.6 ㎏/$m^2$:The 13.3% of subjects were underweight, while 6.7% of them were overweight. The mean value for body fat was 26.4% and subscapular and tricep skinfolds thickness were 14.2 ㎜ and 16.9 ㎜, and waist-hip ratio was 0.72. The systolic/diastolic blood pressure of the subjects was 115.9 ㎜Hg/70.9 ㎜Hg. Except protein, phosphorous, vitamin E, B_6 and C, the average intakes of energy and nutrients were below the Korea recom-mended dietary allowance (RDA). Especially, intakes of calcium, iron and zinc were the lowest, as <70% of RDA. The proportion of energy derived from carbohydrates : protein : fat was 58.0 : 15.8 : 26.2. The 10 frequently consumed food were ssalbap (47.2/mon), kimchi (35.6/mon), onion (16.8/mon), japgokbap (15.1/mon), sesame oil (14.1/mon), carbonated drink (13.3/mon), grapes (12.7/mon), ice cream (12.4/mon), milk (11.9/mon) and water-melon (10.6/mon). Results of this study could be useful for planning nutrition education programs for female university students in this area to improve their dietary habit and health status.

Industrial wastes from pulp and food plants were treated with microorganisms to clarify organic waste-water and to produce cells as animal feed, and results were summarized as follows. (1) Waste-water from pulp, beer, bread yeast, and ethanol distillation plants contained $1.4{\sim}1.5%$ of total sugar, $0.25{\sim}0.35%$ nitrogen, and biological oxygen demand (BOD) was $400{\sim}25,000$, chemical oxygen demand (COD), $500{\sim}28,000$, and pH, $3.8{\sim}7.0$. The BOD and COD were highest in waste-water from ethanol distillation plants among others. (2) Bacterial and yeast counts were $4{\times}10^4-1{\times}10^9,\;2{\times}10^2-7{\times}10^4/ml$ in waste-water. (3) Bacteria grew better in pulp waste and yeasts in beer, bread yeast, and ethanol distillation waste. (4) Saccharomyces cerevisiae SAFM 1008 and Candida curvata SAFM 70 were the most suitable microorganisms for clarification of ethanol distillation waste. (5) When liquid and solid waste from ethanol distillation were treated with microbial cellulase, xylanase, and pectinase, solid waste was reduced by 36%, soluble waste was increased, and recuding sugar content was increased by 1.3 times which provided better medium than untreated waste for cultivation of yeasts. (6) Optimum growth conditions of the two species of yeast in ethanol distillation waste were pH 5.0, $30^{\circ}C$, and addition of 0.2% of urea, 0.1% of $KH_2PO_4$ and 0.02% of $MgSO_4$. (7) Minimum number of yeast for proper propagation was $1.8{\times}10^5/ml$. (8) C. curvata70 was better than cerevisae for the production of yeast cells from ethanol distillation waste treated with microbial enzymes. (9) S. cerevisiae produced 16 g of dried cell per 1,000ml of ethanol distillation waste and reduced BOD by 46%. C. curvata produced 17.6g of dried cell and reduced BOD by 52% at the same condition. (10) Yeast cells produced from the ethanol distillation waste contained 46-52% protein indicating suitability as a protein source for animal feed.

Climate change has been regarded as one of main factors to change Korean insect pest fauna. Especially, a global warming model predicts to expand habitat for insect pests originated from tropical or subtropical regions. Two insect pests, the beet armyworm (Spodoptera exigua) and the diamondback moth (Plutella xylostella), are known to overwinter in some greenhouse conditions without diapause induction in Korea. There was a clear difference between these two insects in seasonal occurrence. P. xylostella occurred only at early spring and fall seasons, but did not occur during summer. In contrast, S. exigua maintained their occurrence from late spring to fall seasons. This study set up a hypothesis that the difference in the seasonal occurrence may be resulted from variation in susceptibility to high temperature. To test the hypothesis, heat tolerance was compared between these two insects. Exposure to $42^{\circ}C$ for 40 min killed 100% individuals of P. xylostella larvae. However, most larvae of S. exigua survived in response to $42^{\circ}C$ even for 80 min. Heat tolerance varied among developmental stages in both insects. Highest tolerant stages were $4^{th}$ instar larvae and adults for P. xylostella, but $1^{st}$ instar larvae for S. exigua. Pre-exposure to $37^{\circ}C$ for 30 min significantly increased heat tolerance in both insects. Induction of heat tolerance accompanied with significant increase of glycerol contents in the hemolymph in both insects and up-regulation of three heat shock protein expressions in S. exigua. These results suggest that the differential susceptibility to high temperature explains the disappearance of P. xylostella during summer, at which S. exigua maintains its occurrence.

Purpose : Corticosteroid has been used as the mainstay therapy of childhood NS. But SIO is one of the serious complications of long-term steroid therapy, especially in growing children. Recently calcium, calcitonin, PTH, vitamin D and bisphosphonate has been used to treat or prevent SIO in adult, which is rare in children with NS. We studied the effect of $1{\alpha}-(OH)D_3$ and Pamidronate on SIO using dual energy X-ray absorptiometry (DEXA). Patients and methods : We studied thirty patients who admitted in the Dept. of Pediatrics of Kyung Hee Medical Hospital with NS. All patients was received longterm steroid therapy. There was no history of bone, liver, or endocrine disease. The samples, serum protein, albumin, BUN, creatinine, calcium, phosphorus, and BMD were obtained before and the six months after the dose of $1{\alpha}-(OH)D_3$ and Pamidronate, respectively Results : The mean age was $6.9{\pm}3.3\;and\;6.5{\pm}2.5$ years old. The mean duration of steroid therapy was $28.8{\pm}1.8\;and\;27.6{\pm}1.0$ months. The changes of serum protein, albumin, BUN, creatinine, calcium and phosphorus level between pre-treatment and post-treatment did not show statistical significance in both $1{\alpha}-(OH)D_3$ and Pamidronate treatment group. However, BMD was increased in both from $0.472{\pm}0.12\;and\;0.457{\pm}0.10\;g/cm^2\;to\;0.533{\pm}0.12$ and $0.529{\pm}0.09\;g/cm^2$ after treatment. (P<0.05) Conclusion : Both $1{\alpha}-(OH)D_3$ and Pamidronate appears to be effective in treating and preventing SIO in children with nephrotic syndrome requiring long-term steroid therapy.

The experiment was carried out from January through December in 2008 at Chungnam National University and the Unbong Animal Genetic Resources Station, NIAS. The experimental animals were twelve dairy goats (female, $30{\pm}1.8kg$), twelve Korean native Boats(female, $24{\pm}2.4kg$) and five sika deer(female, $92{\pm}5.2kg$). A total of 11 different types of hay and straw were tested in this study: such straw imported from USA in 2006 as annual ryegrass, perennial ryegrass, tall fescue and Kentucky bluegrass, and such hay imported from USA in 2007 as alfatfa, bermudagrass, timothy, kleingrass, oat and orchardgrass, and such domestic hay as mixed hay There were significant differences in chemical composition and in vitro dry matter digestibility (IVDMD) among the various types of imported hay and straw (p<0.05). Besides alfalfa hay and orchardpass hay all of the imported hay contained lower crude protein (CP) and IVDMD but contained higher neutral detergent fiber(NDF) and acid detergent fiber (ADF) than the domestic hay. According to the kinds of the imported hay, relative feed value (RFV) made the difference and the hay grades were ranged from 4 to 5, based on the RFV. According to the kinds of the imported hay, there were markedly differences in dry matte. (DM) intake and palatability ranking among dairy goats, Korean native goats, and sika deer. DM intake and palatability ranking were high in common between orchardgrass hay and bermudagrass hay, but Kentucky bluegrass straw, tall fescue straw, perennial ryegrass straw and annual ryegrass straw were proved to be very low in DM intake and palatability ranking. In conclusion, the quality and palatability among the imported hay that was tested in the study were quite variable and lower than expected. It is required to establish a better feed evaluation system for the imported hay.

This experiment aims to observe the nutritive value of blood sausages by manufacturing three kinds of them in order to utilize various by-products of swine when it is processed. In attempt to do so, five different diets were made: one control diet and four diets in which three kinds of blood sausages(blood sausage-1 was made with sausage meat 10%, fat 40%, blood 20%, skin 20% and liver 2%. blood sausage-2 was made with ham meat 30%, fat 20%, blood 20%, liver 2% and skin 20%. blood sausage-3 was made with smoked ham patch 30%, fat 20%, blood 20%, liver 2% and skin 20%) and mixed sausage(sausage meat 20%, fat 10% and fish meat 35%) were mixed with control diet at the rates of 10% respectively. These diets were fed to growing male and female albino rats for 6 weeks. The results obtained through this study are summarized as follows. In body weight gain of male rats, blood sausage-1 and 2 groups were significantly higher than mixed sausage group during the experimental period, and in that of female rats, control group and blood sausage-1 group were similar, but the other groups were lower than control group. Food intake was different in each group every week, but the amount of that was similar to each one throughout all experimental period. Food efficiency ratio and protein efficiency ratio in male were similar in each group, but slightly different in female during the feeding period. Liver weights of male in mixed sausage group and blood sausage-3 group were lower than those in control group and blood sausage-2 group, but liver weight of female in blood sausage-2 group was lower than that in control group. And all groups were similar in liver weight per 100 g of body weight. Mixed sausage group and blood sausage-1 group were lower than control group in kidney weight of male, and blood sausage-1 group was lower than control group in kidney weight of female. Kidney weight per 100 g of body weight of male showed that blood sausage-1 group was lower than the other groups. Spleen weight was similar in all groups. Hematocrit and hemoglobin contents in blood, total protein, albumin, albumin/globulin ratio, total lipid and total cholesterol contents in serum were showed almost similar in all groups.

In order to obtain the basic informations on the production of single cell protein from ethanol, 145 yeast strains utilizing ethanol as a sole carbon source were isolated from 32 soil samples in Korea. A yeast strain showing the highest cell yield among the isolated strains was selected and identified. The optimum culture condition, utilization of other carbon sources and the cultural characteristics for the selected yeast, and the chemical analysis of the yeast cell composition, and utilization of ethanol by the selected yeast were investigated. All the culture was carried out in the shaking flasks. The results obtained were as follows: 1. The selected yeast strain was identified as Debaryomyces nicotianae-SNU 72. 2. The optimum composition of the medium for the selected yeast is : Ethanol 40 ml, Urea 0.5 g, Potassium phosphate (dibasic) 0.5 g, Ammoium phosphate (monobasic) 0.15 g, Magnesium sulfate 0.05 g, Calcium chloride 0.01g, Yeast extract 0.005 g, Tap water 1000 ml. 3. The optimum pH was 5.0-5.5, the optimum temperature $30-33^{\circ}C$ and the aerobic state was unimportant. 4. Utilization of methanol, n-propanol, iso-propanol, n-butanol, iso-butanol, tert-amyl alcohol and acetic acid by the selected yeast was very weak. So substitution of the subtrate was thought to be impossible. 5. Studies on the propagation of the yeast cells showed that the lag phase of the yeast cells lasted 16 hours, and the logarithmic growth phase extended 16 to 28 hours. The specific growth rate was about $0.19\;hr^{-1}$ and the doubling time was 3.6 hours during the logarithmic growth phase. 6. As the result of the chemical analysis of the dry yeast cells, the content rate of the crude protein was 55.19 %, the content of others was similar to the average content of the yeast component. 7. After 34 hours cultivation, under the optimum culture condition investigated, the dry cell yield against the amount of the added ethanol was 53.4 % (W/V%), the dry cell yield against the amount of the utilized ethanol was 73.6 % (W/V%), the evaporation rate of ethanol was about 19.1 %.

The sensitivity and specificity of crude and affinity-purified antigens of Clcnorchis sinensis obtained from the infected rabbits were studied. Stage-specific antigenic proteins from the eggs, metacercariae and adult worms were characterized by SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and enzyme-linked immunosorbent astray (ELISA). The results were as follows: 1. The antibody.binding antigen (ABA) purified from whole worm crude antigen (IVWA) by CNBr-activated Sepharose 4B affinity chromatography made :l specific bands against rabbit antisera on Ouchterlony gel diffusion plate, while WWA made 7 bands. Major WWA protein bands by SDS-PAGE were found at 16, 300~18, 500 and 28, 000~29, 000 daltons, while major ABA protein bands were at 18, 000~21, 000 and 29, 000~31, 000 daltons. The reactivity of ABA with rabbit anti-sera in ELISA was remarkably less sensitive than that of WWA. 2. Molecular weights of egg antigen (EGA), metacercarial antigen (MEA) and adult worm antigen (WWA) of C. sinensis ranged from 15, 000-200, 000 daltons, 15, 000-100, 000 daltons and 11, 000~80, 000 daltons, respectively. Major WWA proteins consisted mainly of polypeptide bands of low molecular weight, less than 31, 000 daltons, while those of EGA and MEA consisted of higher molecular T.eights than 30, 000 daltons. 3. The ELISA reactivities of WWA to rabbit anti.sera were remarkably greater than those of MEA. EGA showed negative reaction throughout the experiments. WWA showed higher optical density (O.D.) than 1.0, when reacted with rabbit anti-sera obtained at 4~6 weeks after the infection. In the rabbit anti-sera later than 12 weeks after the infection, the O.D. reacting witll WWA showed a plateau without variation. MEA shoT.ed relatively low O.D. values (<0.6), when reacted with anti-sera from lightly in(ected groups throughout the experiments, althougll there were some wealth positive cases (O.D.>0.6) ill heavily infected groups. MEA reacted with rabbit anti-sera showed negative results on Ouchterlony gel diffusion plates. Summarizing the above results, it is suggested that the whole worm antigen prepared from the adult worms of C. sinensis is most highly antigenic. However, this antigen might reveal cross reactions with other trematodes such as Paragonimus westermani, therefore, purification of antigenic proteins from the crude antigen is essential 18 increase the sensitivity and specificity for the immuncdiagnosis of clonorchiasis.
