허만규,이송진,허홍욱 한국환경과학회 2003 한국환경과학회지 Vol.12 No.3

This study was attempted to analyze sophomores' consciousness for environmental problems. In order to achieve this purpose, a method of questionnaire was administered to total 387 students selected from four universities in Busan. There were surveyed questions as follows, the conception of environmental problems, the condition of dwelling place and surrounding of home, the problems of environmental pollution, knowledge and concern for environmental problems, necessity of environmental education of school, and the environmental policy in Korea. Most students responded that the most serious environmental problem is water pollution. Most respondents have recognition the necessity of schooling for environmental education, whereas current-contents of environmental education are not enough to modify students' attitude and behavior.

허홍욱,허경혜 釜山大學校 師範大學 1993 교사교육연구 Vol.27 No.-

The genetic variation in the Korean populations of Everning Primrose, Oenothera odorata L., was examined to check out the frequency of allozyme variation. The allozyme variation of ADH, MDH, 6-PGDH, PGM, and IDH were assayed by means of starh gel electrophoresis. The ADH, 6-PGDH and PGM loci were almost monomorphic which was under control of one locus. Only Seol-ag population shows slow allele(3.0%) at the ADH-locus. At the MDH-2 locus, the frequency of slow and fast allele were 5.9% and 4.5% on the average, this represented a single locus with two alleles for a dimeric enzyme. And also IDH-locus were 0.7% and 3.6% respectively. Fatty acid comosition were investigated by means of capillary column gas-chromatography. The fatty acid of Everning Primrose oil was composed of palmitic(5.79-7.48), stearic (1.51-1.79%), oleic(4.15-7.81%), and linoleic(71.37-76.38%) acid. Particularly, GLA which is a precursor of prostaglandin was 10.15-12.51% among total fatty acid.

Enzyme electrophoresis was used to estimate genetic diversity and population structure of Robinia psudoacia L. in southern part of Korea. The percent of loci polymorphic per population was 77.8%. Genetic diversity at the species level was high (Hes = 0.346; Hep = 0.336), whereas the extent of the population divergence was relatively low ( = 0.04). F, a measure of the deviation from random mating within the 7 populations, was 0.332. Indirect estimate of the number of migrants per generation (Nm = 6.03) indicates that gene flow is high among Korean populations of the species. In addition, analysis of fixation indices revealed a substantial homozygosity deficiency in some populations and at some loci. This indicates that some populations sampled may have been substructured largely due to outcrossing mating system and widespread gene flow coupled with Wahlund effects and low genetic drift.

The study is to analyze the middle school-science parts among the products of nation-wide science exhibition for eleven years recently and the results of compared to the content of science-textbooks of middle school. The number of observation in the student parts among the products of nation-textbooks of middle school. The number of observations in the student parts among the products of nation-wide science exhibition was the highest in all methods studied, whereas, most teachers surveyed experiments in their products. The mean Shannon's diversity index (DI) was same trend for students and teachers. There was a non-significant difference of the methods in students and teacher groups according to years and the association between students and teachers were closely connected with methods. The correlation between the content of students' products and texts of middle-school was highly positive for earth science, chemistry, and biology, whereas physics showed negative correlation.

The genetic variation in the Korean populations of common buckwheat, Fagopyrum esculentum Moench, was examined for the frequency of detrimental genes and allozyme variation. The frequency of detrimental genes per gamete was estimated by performing sull-sib matings and subsequent observation of F_2 segregation. The frequency of sib lines which segregated chlorophyll-deficient mutants was 18.4% at the cotyledon stage, and 7.1% at the foliage leaf stage. Following types of abnormalities were observed in the cotyledons; yellow (3.6%), pale yellow(5.2%), pale green (6.4%), variegated (1.4%) and morphological (1.8%). Each type was also found in the foliage leaves at about half of the frequencies in the cotyledons. The frequency of mutants affecting the cotyledons and foliage leaves does not vary among the Hong-cheon, Jeon-gok and Che-ju populations. By estimating the frequency of mutant allele at each locus, it was concluded that the equilibrium frequency at each locus is very low simlar regardless of locality, and that the chlorophyll-deficient mutants are maintained by mutation-selection balance. This may be expected if the Korean populations without systematic breeding. The frequency of recessive male and female sterility mutants was also investigated by examining the segregation of such mutants in the same full-sib families, as used for the detection of chorphyll-deficient mutants. The aberage frequency of male sterility mutant was 14.1% per gamete and that of female sterility was much lower than male sterility, and it was the same among the three populations. By the sta tistical analysis, it was revealed that male and female sterilities were mostly caused by different genes, and no geographical variation was found in the Korean populations. The allozyme variation for alcohol dehydrogenase (ADH), NAD dependent malate dehydrogenase (MDH), phosphoglucomutase(PGM) and 6-phosphogluconate dehydrogenase (6-PGDH) was assayed by mans of starch gel electrophoresis. ADH was monomorphic in all of the the Korean populations examined, but several seeds were apparently heterozygous for rare mutant alleles. The MDH-1 locus was shown polymorphic and the frequency of minor fast allele was 25.5% on the aberage. However, the Dun-nae population showed a low frequency of the minor allele(14.7%). The genetic distances between the Dun-nae population and the other Korean populations are slightly larger than others reflecting the significantly lower frequency of the fast allele at the MDH-1 locus in Dun-nae. At the 6-PGDH locus, the frequency of minor slow allele is only 1.5%. Furthermore, another minor fast allele was occasionally observed in three populations, but its frequency is extremely low, ranging from 0.3 to 0.8%. For the PGM locus, all of the six populations showed triallelic polymorphism. The frequencies of fast and slow minor alleles were approximately equal, being 4.7% and 6.0%, respectively. As the result of the allozyme variation, the gene frequency of the Korean populations was similar to that of the western population of Japan. This may lead to the conclusion that the Korean populations are closely related to the western populations of Japan.

For a long time, levee-burning in Korea have been conducted to kill the fauna of insect pests. We conducted to find out whether the levee-burning could justifiable for the suppression of insect pests, partially the spider. Density of both pest and enemies grew higher in burned areas than in unburned from about 90 days after the levee-burning. Density surveys on pests and their enemies(mostly spiders) was carried out unto the mid May at an experimental paddy field located in Kimhae. Wingless spiders could requires even larger time than winged pest species to re-establish in the center region of the widely burned field. However, according to the present point of view, the opinion that levee-burning is helpful for controling pests which over winter on levee areas could not be justifiable.
