최승윤,배상희,송유한,Choi Seung Yoon,Bae Sang Hee,Song Yoo Han 한국응용곤충학회 1970 한국식물보호학회지 Vol.9 No.1

본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

Lymphangioma는 림프관에 나타나는 양성종양으로 림프관의 증식을 특징으로 한다. 이 종양의 대부분은 출생 시에 나타나며 종양의 95%정도가 10세 이전에 나타난다. 구강 내에 발생하는 경우에는 혀에서 가장 호발하며 거설증을 야기한다. 대개 양측성으로 혀의 전방 2/3부위에 나타나며 불규칙한 회색과 핑크빛을 띤 소절형태를 보인다. 본 증례 모두에서 환아들은 출생당시 혀에 lymphangioma를 지니고 태어나 거설증을 보였으며 이로 인해 개교합과 하악과성장 양상을 나타내었다. Lymphangioma에 의한 비정상적인 혀의 비대에 의해 환아의 구강과 두개안면부의 주위조직에 대한 적응 결과로 나타난 소견을 관찰하고 관련문헌을 고찰하여 다소의 지견을 얻었기에 보고하는 바이다. Lymphangioma is a benign tumor of lymphatic vessels. The majority of cases are present at birth and 95% of the tumors aroused before the age of 10 years. Oral lymphangioma may occur at various sites but are most frequent on the anterior two thirds of the tongue, where they often result in macroglossia. The lesions present nodularity with gray and pink projections. In the present cases, all the patients who had the macroglossia combined with lymphangioma showed openbite and mandibular prognathism. The purpose of this paper was to report the dental and craniofacial findings of macroglossia combined with lymphangioma and review the pertinent literature through the cases.

Folk-songs are the songs which are sung by farmers. Thus, the aim of this study is to observe the social characters of Korean peasantry through folk-songs, and tried to approach with the method of socio-linguistical study. Characters are formed through the process of life in family formation and village structure. The society of Lee Dynasty which is the object of this study was feudalistic one, and the order of social position was regarded as important, and the possession of the lands was concentrated on the aristocrat. In such seciety as Lee Dynasty, formed by power-structure of progressive and class-consciousness, the peasantry was forced to be subordinate to the aristocrat in social position and possession of the lands as the tenants. Besides these situation, the peasantry had strains in econcmical and social life due to the weather conditons such as floods and drought. In such natural and social circumstances, the following characters of peasant were formed; (1) abandonment, (2) epicrism, (3) humor, (4) dependence, (5) conservatism(traditionalism), (6) eroticism, etc. Such characters are regarded as those of peasantry, and these characters are able to be found in the many phases of the folk-songs.

To obtain basic data for water quality management and improvement of A-stream located at changwon city, this study was carried out to investigate and estimate flowrates and the characteristics of water pollutants such as organics and nutrients etc, discharging into main A stream where located to flow at commercial and residential areas. A stream was divided five section and field studies have been from June 1997 to May 1998 for one year. The results obtained from this research were follows. The flowrates at the lower site(A-5) of A stream were varied from 19,967 ㎥/day in winter to 29.074㎥/day in summer season. And BOD and COD concentrations at the same sampling site were yearly mean values 45.4㎎/L and 21.38㎎/L, and loading rates 1042.7㎏/d and 548.1㎏/d, respectively. The ratio of BOD loading in A-3 to A-5 to total section were occupied 0.90. T-N and T-P concentrations were obseved average values 27.79㎎/L and 1.47 ㎎/L yearly, loading rates 477.04 ㎏/d and 29.75 ㎏/d, respectively. The value for ratio of T-N loading in A-3 to A-5 to total section were 0.86. similar to the above value, 0.90 for BOD loading ratio. It is consequently necessary to take into account that the policy and master plan must firstly be to reduce pollutants loading rates inputing into A-3 to A-5 at A stream.

Effect of p-Phenylenediamine Application to Rat Skin on the Liver Oxygen Free Radical Systems

윤종국,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2003 Journal of biomedical laboratory sciences Vol.9 No.2

To evaluate the influence of hepatic oxygen free radical systems on liver injury by topical p-phenylenediamine (PPD) application on rat skin. PPD (25mg/16.5㎠) was topically applied to the abdominal region 5 times every other day and sacrificed. By PPD treatment, increasing rate of liver weight/body weight(%), serum activities of alanine aminotransferase and aspartate aminotransferase and decreasing rate of microsomal glucose-6-phosphatase activity were higher in the rats fed tungstate supplemented diet than those fed a standard diet. These findings indicate that group fed tungstate supplemented diet have more severe liver injury compared with group fed standard diet on topical PPD application. However, the activities of oxygen free radical generating enzymes such as xanthine oxidase (XO) and cytochrome P450 dependent aniline hydroxylase and those of oxygen free radical scavenging enzymes were not found to be different between these two animal groups. In the present study, a novel monitoring method to detect the generating of oxygen free radicals in liver extract was devised. Throughout this method, the oxidized PPD produced by oxygen free radicals was determined colorimetrically. The increasing rate of PPD oxidation by liver homogenate was higher in tungstate fed animals than in standard diet fed ones. Among the fractionations of liver extract, the mitochondria1 and postmitochondrial fractions in the liver extract of tungstate fed animals led to a higher availability of PPD oxidation by PPD treatment compared with standard diet fed ones. In conclusion, these results suggest that an enhanced liver injury in tungstate fed animals treated with PPD may be due to oxygen free radicals produced in other systems except oxygen free radicals generating from cytosolic XO system. Especially, oxidative availability by PPD can be used for oxygen free radical detection in some tissue.

The purpose of this inquiry is to understand the changing process of Tae-Kwon Do uniform by After thorough examination, they could be summarized as below. Tae-Kwon Do training uniforms are divided into two different types. One is a spread extended type which originally came form Japan and the other is an Korean traditional martial arts uniform. As the development of Tae-Kwon Do occurred, the uniform changed into a basic clothing form from the three countries period which included a black collar and a half black and red collar for grade holders. The differences in the length of sleeves and pants come from which material it is made of and a statement regulated by the Korea Tae-Kwon Do Federation. The uniform currently using is not the Korean traditional type which has to be worn over the head. This has a major disadvantage when putting it on and taking it off, it ruins the hair especially after sweating a lot through training. As a result, the uniform we are currently wearing has a slight problem in practicality and the historical background but the uniform itself is rogarded more as a sport uniform rather than a training uniform.

The social trouble to the durability of concrete rises recently because the embedded rebar corrosion influences concrete structures to deteriorate structural capacity. And also, the rebar corrosion causes crack of concrete, decrease of steel section and separation of covering concrete. In the result, the bond strength of concrete and embedded rebar decreases, which causes deterioration of the structure behavior in reinforced concrete. In this study, the relation of bond strength and bond-slip was understood to evaluate capacity deterioration of reinforced concrete, and experiments were carried out by compressive strength and embedded rebar condition in the rebar corrosion rate.

This study was to provide the fundamental data for vegetation recovery and efficient management of fire-burned forest area. For the purpose of this study, natural and artificial forests reproduced after fire burning were selected, including 7 sites of natural forests consisted of various fire-burned dates and 4 sites of artificial forests of 4 dominant tree species, Larix leptolepis, Pinus rigida, Chamaecyparis obtusa, Robinia pseudo acacia, and were investigated about species compositions and diversities. Obatained results are as follows : 1. By the community differential table the plant communities of this area are classified by Quercus acutissima - Lespedeza bicolor - Pteridium acquilinum community, Q. dentata - Pinus densiflora community, and Q. mongolica - Rododendron mucronulatum -Miscantus sinensis community centering around Quercus spp. in natural forests, and each Larix leptolepis, Pinus rigida, Chamaecyparis obtusa, Robinia pseudoacasia community consisting of species planted for the afforestation in artificial forests. 2. Natural forests are appeared to possess abundant species as the mean no. of species occured in the area are 49 species of natural forests and 39 species of artificial forests, and No. of species occured only in the natural forests and the artificial forests are 37 species and 31 species, respectively. 3. In natural forests Quercus acutissima, Quercus mongolica, and Rhododendron mucronulatum had the most high importance value in canopy layer, under layer, and shrub layer, respectively. Quercus mongolica and Rhododendron mucronulatum showed increased importance values with passing time after the fire. 4. In artificial forest, tree species that showed the most high importance value in each canopy - subtree - shrub layer were Chamaecyparis obtusa - Celtis sinensis - Deutzia parviflora in Chamaecyparis forest, Pinus rigida - Quercus acutissima - Quercus mongolica in Pinus rigica forest, Robinia pseudoacasia - Robinia pseudoacasia - Quercus serrata ini Robinia pseudoacasia forest, and Chmaecyparis obtusa - Callicarpa japonica without subtree layer in Chamaecyparis otusa forest. 5. Species diversity (H′) of natural forests was the most low value in Siljun area having the shortiest passing time after the fire, on the other hand Yumboksa area having the longgest one was the most high value and in artificial forests Larix leptolepis forest showed the most high value and Robinia pseudoacasia the most low one with the highest dominance. For species diversity of each crown layer, subtree layer in natural forests and shrub layer in artificial forest showed the most high value.
