This study was aimed to determine the effect of high molecular weight chitosan treatment on the decay incidence and fruit quality in strawberries. Preharvest spray of chitosan (0.2%) effectively reduced the incidence of grey mould and increased fruit firmness. Chitosan application was also effective on remaining of surface gloss. This is probably due to coating effect. Physiological disorders were not found in treatment of 4 sprays. Internal quality such as soluble solid content and acidity seemed not to be affected by chitosan application. The effect of chitosan on keeping freshness was clear in fruit without physical damage at harvest, but muck less effective in injured fruit. Postharvest application of chitosan did not affect fruit quality. Above results indicated that chitosan is an alternative to keep strawberry quality through delaying decay and keeping firmness.

This study was performed to analyze general components such as, organic acids, alcohols and minerals in persimmon vinegar made with quick fermented using deteriorated sweet persimmon and four commercial vinegars(rice vinegar, apple vinegar, brewed vinegar, traditional persimmon vinegar) purchased in local markets for quality evaluation. The pH and total acidity of all vinegars were in the range of 2.02~3.02 and 4.62~9.78%, respectively. The pH of quick fermented persimmon vinegar(A) was relatively higher than that of others. Acidity was the highest in brewed vinegar. Total sugar content was in the range of 0.45~6.43%. These contents were high in were high in traditional persimmon vinegar wherase low in brewed vinegar. Total nitrogen and amino-nitrogen were in the range of 0.025~0.046% and 0.015~0.029%. Organic acids were identified as acetic acid, citric acid, tartaric acid, malic acid, succinic acid, formic acid and oxalic acid. While major minerals of all vinegars were Mg, Ca, and Na, minor minerals were Zn, Cu, Mn and Fe.

목적 : 기능성 소화불량증은 소화, 흡수등 장관의 기능적인 이상과 관련되어 있을 것으로 생각되며 복합소화효소제(Winstal®)를 투여하여 그 임상효과를 평가하고자 본 연구를 실시하였다. 대상 및 방법 : 1994년 3월 부터 6월까지 경북대학교병원 내과를 방문한 기능성 소화불량증을 호소하는 환자 20명을 대상으로 Winstal®을 1회 1정씩, 1일 3회 식후 30분내에 경구로 2주간 투여하였다. 결과 : 소화불량증의 증상은 복부불쾌감, 복부팽만감, 식욕부진 및 오심, 복부동통, 공기연하증, 고창 및 구토순이었으며, 증상의 개선은 복부불쾌감이 76.4%(13/17)로 가장 높았으며, 그 다음으로 복부팽만감 및 공기연하증이 66.5%(10/15, 6/9)이었고, 오심 61.5%(8/13), 식욕부진 53.8%(7/13), 복부동통 41.6%(5/12), 고창 37.5%(3/8)이었다. 각 환자별 종합적인 증상의 개선도는 현저한 개선이 2예(10%), 중등도 개선이 3예(15%), 약간개선이 11예(55%), 불변이 4예(20%)이었으며 종합적인 유효율은 80%(16/20)이었다. 부작용은 한 예에서도 관찰되지 않았다. 결론 : 본 제제는 기능성 소화불량증 환자의 증상개선에 추천할 만한 유효한 약제로 생각된다. Dyspepsia is a common symptom in gastroenterologic practice and trigger for numerous consultations with physician. The treatment of chronic functional dyspesia is unsatisfactory. This study was performed to evaluate the efficacy of the digestive compound (Winstal®) on 20 functional dyspepsia patients. On open trial, all patients were given 6 tablets daily for 2 weeks and we evaluated the efficacy of this preparation according to the degree of the improvement. The improvement of symptoms was 76.4%(13/17) in abdominal discomfort, 66.5%(10/15, 6/9) in abdominal distension and aerophagia, 61.5%(8/13) in nausea, 53.8%(7/13) in abdominal pain, and 37.5% (5/12) in flatulence, respectively. Overall effectiveness of subjective symptoms was 80% (16/20) and there were no untoward effects of the preparations during this study. As a result, We think that this preparation is an effective one to relieve symptoms of functional dyspepsia.

This study was carried out to evaluate the feasibility of current lead indicators used in screening lead who were sspeted to have been exposed to lead were selected as 'case'and 207 female workers from non-lead industry were selected for 'control'. The results obtained were as follows: 1. The mean values of blood lead for case and control were 31.4㎍/dl, 22.2㎍/dl,respectively. The difference observed in the mean concentration between case and control was statistically signifi-ant(P<0.01) 2. The mean values for blood ZPP by hematofluorometer for case and control were 31.3㎍/dl, 25.4㎍/dl,respectiely. And difference between two groups was statistically significant(P<0.01). 3. No statistically significant correlation was found between working duation and blood lead, blood ZPPlovel. 4. According to the simple correlation analysis,ZPPand urine lead were found to be statistically correlated with blood lead(P<0.01) 5. According to the discriminant analysis using blood lead as a dependent variable, it showed 89.1% predictability when using 40㎍/dl as a cutting value which is used as a screenig cutting value for industry workers health examination, while 81.8% for 30㎍/dl,77.54% for 20㎍/dl, respectively. 6. Lead related simptons which is used for screening the lead ntoxicated patients were used as a dependent variables in multiple regression analysis to find useful lead indicator. And significant independent variables were found to be ZPP, Age, and Hct. 7. Above results suggest that objective evalution of feasibbility of several lead indicators should be developed to correct the disutility of current lead screeng system in Korea.

To utilize abundant poor persimmon fruits effectively, it was studied on alcohol fermentation strains which were isolated and indentified from poor persimmon fruits. The strains which had exellent alcohol production ability were analysized morphogical, cultural characteristics and identified Saccharomyces cerevisiae YJK 20, Sacahroimyces kluveri DJ 97. Alcohol production ability between the isolated strains and industrial alcohol yeasts was compared in the YPD medium, persimmon extract medium. Isolated strains had high alcohol production ability in both of two medium, respectively. So it was expected that the strains, YKJ 20 and DJ 97 had good alcohol fermentation ability of persimmon fruits.

This study was designed to compare the understanding of ordinary elementary school students and scientifically gifted students about scientists. 473 fourth, fifth, and sixth graders in ordinary elementary schools and 40 students attending scientific educational institutions for the gifted were studied with the help of questionnaires and interviews. The survey showed that there were no significant differences between the two subject groups in relation to the external images of scientists. The subjects turned out to have four fixed external images. The scientifically gifted students had a better understanding of the internal images of scientists than ordinary elementary school students. Both the subject groups turned out to be influenced by the press media and off-campus education, thinking that scientists served as inventors producing something useful in daily life rather than as researchers studying natural phenomena or laws. It was found out that both groups admired Edison. The ordinary students respected Einstein and Jang Yeong-Sil whereas the scientifically gifted students respected Curie, Jang Yeong-Sil, and Nobel. The subjects admired them because of their achievements instead of their backgrounds or individual characteristics.
