The goal of this study is to find out the main trends in the transition of the traditional townscape of the two major provincial cities of Korea, Jeonju and Taegu, from 'The Port Opening Treaty' with the foreign countries (1876), down to the present, and to find out the specific characteristics of the townscapes maintained scince then, in spite of many historical transitions, for the purpose of preparing the concept which can strengthen the identity of the contemporary Korean Townscapes. The methods of this study depend largely upon analyzing the city maps produced in each period and investgating the common literatures about the cities. The main finding of the study are as follws; 1) During the period of 'The Port Opening Treaty' and 'The Japanese Colonial Era', the most part of the pre-industrial Korean townscape began to change into the modern one(e.g. demolition of the city wall and straightening of the existing organic road form, etc.). 2) During Japanese colonial era, the townscapes ultimately showed a dual structure presenting a contrast between the the traditional and modern art. 3) After the liberation from the colonial governing, up to the present, the major trends in the city development mostly have succeeded the former age's urban plan and have overlapped the new dual structure upon the pre-existing one, to be the multiple structure in a larger scale. 4) Although, these townscapes have changes greatly from the modern age up to now, they also have retained the historical inertia, especially in terms of the street pattern and the land use pattern. According to the survey about the public cognitions toward the townscapes, it is confirmed that public cognitions tend to concentrate on the townscape elements or areas which retain this historical inertia. And these elements or areas seemed to be such the most important ones as to be preserved and interconnected carefully, in order to strengthen the identity of the Korean townscapes.

The effects of high temperature on the style elongation and the pollen fertility were investigated in different ecotypes of tomato. 'Moneymaker' and the two breeding lines named 'CL 1131' seemed to be heat-tolerant cultivar with appearance of abnormally elongated style and the pollen fertility to abnormally elongated style and the pollen fertility to high temperature. To investigate the germination ability and fertility of pollen, anthers were detached and pollens were incubated under the different temperature(15~35℃) on the agar medium. The optimal temperature for pollen fertility was 25 to 35℃. 'Moneymaker' was the highest and 'Ogata Zuiko' was the lowest rates of pollen fertility in all the treatments. For the pollen germination, the optimal temperature was 25℃ in all the cultivars, but at 35℃ they lost the ability of pollen germination. 'Moneymaker' also had a high ability than the other cultivars. Under the serious conditions in the growth chamber, all the three cultivars showed the high temperature injuries in vegetative and reproductive growth. But 'Moneymaker' is superior in fruit set than the other two cultivars under high temperature conditions.

길항균 Streptomyces sp. A 171 균주의 항균효과 및 배양적 특성

The powerful antagonistic actinomycetes, strain A 171, to powdery mildew(Erysiphe graminis DC f.sp. hordei Marchal) was identified to be Streptomyces species. The cultural filtrate of the Streptomyces sp. A 171 showed antifungal effect against the tested six soilbrone plant pathogenic fungi. Distinct antifungal activity was showed in tryptic soy broth medium at pH 6.5 and 30℃ during 72 hrs culture. The antifungal activity was stable in the pH range of 4 to 12 and high temperature(121℃).

This research was conducted to comparison of capacitation time of spermatozoa and insemination time on in vitro fertilization using out-bred ICR mice. The results obtained are as folows, 1) Optimum capacitation time of spermatozoa was 2 hours, when in vitro fertilization rate was 81%. 2) Optimum insemination time of sperm and oocyte was 6 hours, when in vitro fertilization rates were 81% and 76% in T6 and TYH media.

당근 Brown anther type과 Petaloid type의 雄性不稔系統間의 採種量 比較

This experiment was carried out to check the difference of the seed production ability between the brown anther type and the petaloid type male sterile lines in carrot. The seed production per a seedling stock of the brown anther type male sterile lines was higher than that of the petaloid type at every experiment. The mean seed production per a seedling stock of the brown anther type was high about 60% as compared with that of the petaloid type at Experiment House-1, 40% at Experiment House-2 and 20% at Experiment House-5. And at the remaining two experimental houses the seed production per a seedling stock of the brown anther type male sterile lines was higher thatn that of the petaloid type but there were no significant differences between the two types of male sterile lines. The seed production per a second umbel of the brown anther type male sterile lines was higher than that of the petaloid type but the number of second umbels per a seedling stock did not show consistant relationship between the two types of male sterile lines. As a result it seemed that the difference of the seed production per a seedling stock between the brown anther type and the petaloid type male sterile lines was due to the difference of the seed production per a second umbel between the two types of male sterile lines.

This study was executed to investigate the avifauna in Kyongsan campus of Taegu University. 40 species and 618 individuals of wildbird were observed in campus and those consis of 18 species for resident. 18 species for summer visitor, 3 species for winter visitor and 1 species for passage migrant. The living density was averagely 4.79 birds per hectare and the dominant species were Passer montanus(24.27%), Hirundo rustica(12.62%), Paradoxomis webbiana(10.68%), Parus major(7.93%), Pica pica(5.66%), Streptopelia orientalis(4.69%) in order. Number of species and individuals and species diversities were higher in survey route II(light-used area) than in survey route I(heavy-used area). Also species diversity was the highest in June for 1.2265 and the lowest in September for 0.9076. Similarity index between two areas according to difference of use intensity was 68.85% and those indices by month represented seasonal migrations of wildbirds considerably.

In order to facilitate deinking and to obtain an improved brightness of the deinked stock, soaking tower systems was performed on korean old newspaper. In soaking system, alkaline hydrogen peoxide as a bleaching chemical was used. The test results with soaking tower systems showed a sharp increase in deinkability. This good deinkability mainly depended on soaking time and deinking chemicals. In soaking system, good brightness response on KONP was obtained with up to 1% peroxide applied, however, increasing the application level further gave only incremental improvement. Soaking time must be longer than 4 hours to obtain the sufficient effect, and 8 hours of soaking is of no practical value.
