Body fluid Lactate dehydrogenase and its isoenzyme measurement was performed in 132 patients: 8 cases with peritonitis, 21 cases with malignant ascites, 43 cases with liver cirrhosis, 48 cases with tuberculous pleuritis, 12 cases with malignant pleural effusion respectively. Body fluid protein and glucose contents, red blood cell counts, white blood cell counts, cytologic examination were also performed as a comparative study. The results were as follows: 1. Measurement of total LD and protein amount could differentiate between transudate and exudate in the ascitic fluids. 2. In the malignant exudate of ascites and pleural fluid, the activity of LD2 isoenzyme was statistically increased compared with that of inflammatory exudate and the activity of LD4 isoenzyme was also increased compared with that of serum(P<0.05). 3. The inflammatory exudate of pleural fluid and ascites demonstrated the increase of LD5 isoenzyme activity stastistically compared with that of serum and malignant exudate(P<0.05). 4. A difference of total LD activity between malignant ascites and inflammatory ascites was significant statistically, while this was not observed in the pleural exudate. 5. Total LD and LD5 isoenzyme activity didn't correlated with the number of white blood cells in the exudate.

This study was carried out to investigate functional quality characteristics of extract obtained after sugar-leaching for 12 weeks (SLE) and extract obtained after lactic acid fermentation for 8 weeks (LFE) of mulberry leaves. The yield, sugar content, pH, and total acidity of SLE were 27%, 43 $^{\circ}Brix$, 4.6, and 0.45%. The yield, sugar content, pH, and total acidity of LFE were 166%, 33 $^{\circ}Brix$, 3.6, and 1.17% respectively. The lactic acid bacteria viable numbers ($1.2{\times}10^{10}$ CFU/ml) of LFE were more than those of SLE ($2.8{\times}10^2$ CFU/ml). The LFE expressed activities of hydrolytic enzymes (amylase, cellulase, pectinase, protease), but SLE did not express. The contents of acetic acid, citric acid, and malic acid of SLE were higher than those of LFE, but lactic acid content of LFE was higher than that of SLE. The main free sugars of SLE were glucose (200.93 mg/g), fructose (236.32 mg/g), and sucrose (18.41 mg/g), but LFE did not detect all free sugars. The contents of polyphenol, anthocyanin, and piperidine alkaloid of LFE were higher than those of SLE. ${\alpha}$-Glycosidase activities were inhibited 3.4% and 16.2% by SLE and LFE. These results suggest that lactic acid fermentation extraction is an effective method to increase the yield and contents of functional quality of mulberry leaves extract.

The effect of sodium metabisulfite and adipic acid on the color changes of garlic juice was evaluated. The garlic(Uisung variety) juice was extracted and 1% sodium metabisulfite and 1% adipic arid were added to the garlic juice before or after concentration. Garlic juice was concentrated by heating at 90$\^{C}$, by heating using a rotary vacuum evaporator at 45$\^{C}$, or by freeze-drying at -50$\^{C}$ until the volume was reduced to 70% of the original volume. The garlic juice concentrate was kept at 4$\^{C}$ and 25$\^{C}$ for 60 days and evaluated for the color change and the relation between the additives and browning. Browning of the garlic juice concentrate containing adipic acid and sodium metabisulfite was effectively inhibited compared with the control. Inhibition effect of sodium metabisulfite on the browning of the concentrate was stronger than that of adipic acid. The addition of sodium metabisulfite afrer concentration of garlic juice was the most effective on browning inhibition in the 9$\^{C}$-heated concentrate, but the addition of sodium metabisulfite before concentration was the most effective in the 45$\^{C}$-heated concentrate and the -50$\^{C}$-freeze-dried concentrate. In the color change of the garlic juice concentrate during the storage, a and b values of the concentrate with sodium metabisulfite were lower than those of the control, which means that sodium metabisulfite inhibited the browning of the garlic juice concentrate.

Fresh bamboo was charred in the mechanical steel kiln and traditional earth kiln, and then its smoke was condensed to produce bamboo smoke distillates (BSD). BSD made by mechanical steel kiln (MBSD) was purified by distillation. There is significant difference (p<0.05) in total phenol content among them, 663.40 ppm in MBSD, 571.62 ppm in PMBSD, and 485.16 ppm in TBSD. The nitrite scavenging activity and electron donation ability of BSDs were measured and the content of total phenol content was determined. The nitrite scavenging activity of BSD increased with increasing concentration of BSD at the same pH and decreased with increasing pH. There is significant difference (p<0.05) in nitrite scavenging activity among MBSD, purified MBSD (PMBSD), and BSD made by traditional earth kiln (TBSD) and the activity was the highest in MBSD and the lowest in TBSD. The electron donationg ability of BSDs increased with increasing the concentration of BSD and the reaction time. There is significant difference in the electron donation ability of BSDs at the same period and different concentration among the BSDs, the highest in MBSD and the lowest in TBSD.

Crude extracts from 20 species of plants 16 families were evaluated for their antifungal activities against Colletotrichum gloeosporioides, and three plant extracts of them were applied to Ginseng in order to investigate the usefulness for Ginseng anthracnose control. Among the crude extracts from 20 species being tested, it of A. cepa, R. undulatum and C. japonica showed considerably antifungal activity against mycelial growth and conidial germination of C. gloeosporioides.. Ginseng anthranose was controlled at 2% concentration of A. cepa and R. undulatum and 1% C. japonica extract, but control value of three plant extracts was inferior to Mancozeb WP. Phytotoxic symptoms were observed in the leaves of ginseng with exogenous foliage application of 10% concentration of three plant extracts and 2% concentration C. japonica extract but not observed at 1% concentration.

Reusing of electroless Ni-Cu-P waste solution was investigated in the plating time, plating rate, solution composion and deposit. Plating time of nickel-catalytic surface took longer than that of zincated-catalytic surface. Initial solution with 50f) waste solution additive at batch type was possible to reusing of waste solution. Plating time of initial solution at continuous type took longer 10 times over than that of batch type. Plating time of 50% waste solution additive at continuous type took longer 3.7 times over than that of batch type. Component change of nickel-copper for electroless deposition was greatly affected by depolited inferiority and larger decreased plating rate.

여포액이 여포안에서는 난자의 성숙을 억제하지만 여포액을 일단 여포 밖으로 내어 배양액을 섞거나 혹은 여포액만으로 난자를 배양할 때 난자는 성숙분열을 일으키는 것을 보아 왔다. 저자들은 소의 여포액 내의 성분중 어떤 것 들이 난자 성숙에 유효한 가를 밝히기 위하여 본 실험을 행하였다. 그 결과는 다음과 같다. 첫째, 여포액을 투석하여 얻은 dialysable fraction을 이용하여 난자를 배양하였을 때 높은 성숙율을 얻었다. 반대로 non-dialysable fraction를 포함하는 기본배양액 내에서는 난자의 성숙율은 극히 낮았으며 퇴화하는 경향이 있었다. 둘째, paper chromatography 의 방법으로 dialysable fraction이 포함하는 free amino acid를 조사한 결과 8가지의 amino acid가 동정되었다. 이 amino acid를 기본배양액에 섞어 배양액으로 만들어 난자를 배양했을 때 난자성숙율이 90%이상이었고 제 2차 중기까지 도달한 난자는 30시간 이내에 10% 정도였다. 셋째, 상기의 amino acid가 들어있는 배양액에 다시 biotin를 첨가하여 배양하면 48시간내에 제 2차 분열 중기까지 도달하는 난자가 60%에 이르렀다. 위 결과로 보아 여포액은 in vitro인 경우 난자의 성숙을 유발하며 성숙을 유발하는 주요 성분은 여포액내에 포함되어 있는 몇가지 amino acid와 biotin과 같은 vitamine B가 될 것이라는 결론을 얻었다.

재해가 발생하기 전에 피해규모와 이에 따른 영향 및 피해액을 신속하게 추정하는 것은 효율적인 재난 관리를 하는데 있어 중요하고, 더불어 정책결정자들이 의사결정을 할 때 도움이 될 수 있다. 하지만 기존의 연구는 단순 재해 피해발생 후에 그 피해액 혹은 복구액을 산정하는 수준이며, 현재 피해액 추정에 대한 연구는 전무 하며 그 기술개발에 또한 초기단계에 있다. 이에 피해액 추정에 대한 연구가 시급한 실정이다. 실질적으로 자연재해 정보에 대한 수요가 급증하고 있는 반면에 체계적이고 일관된 통계기반의 정보체계는 미흡하다. 이에 국가에서도 재해에 대한 피해액 및 복구비 산정 등 예산편성에 있어 큰 어려움을 겪고 있다. 기존통계 방식에 대한 개선의 필요성 인식과 더불어 본 연구의 목적은 재해 발생 전에 그 피해규모와 영향을 고려하여 이에 따른 피해액을 신속하게 추정하기 위함에 있다. 본 연구에서는 비선형 회귀식을 이용하여 강우-홍수피해액에 대한 함수를 제시하고자 한다.
