Camping activities were thought as one of educational methods. This study analyzed effects of participation in camping activities on high school students` humanity development variables, which affect humanity development were used for this study and data were collected at high schools in Kwang-ju city. At this site 600 surveys were distributed to a random sample of 300 participant and 30 non participant in camping activities. The results were as follows. 1. Participation in camping activities more positively affected humanity developments of male students` than that of female students`. 2. There was significant relationship between camping activities and sociality, leadership, activity and responsibility development. 3. There is no relationship between frequency of participation in camping activities and humanity development. Since the data were collected only at high schools in Kwang-ju city, further studies on high schools in countrysides would be required.

아스팔트 콘크리트는 아스팔트 바인더와 골재의 혼합물로서 역학적 특성은 골재와 바인더의 특성에 따라 크게 좌우된다. 지금까지 골재의 특성에 따른 혼합물의 특성에 대한 연구는 많이 수행되었지만 아스팔트 바인더의 특성에 따른 혼합물의 특성과의 관계는 잘 알려져 있지 않고 있다. 본 연구에서는 폴리머 개지 아스팔트의 역학적 특성과 PG 등급 결정 및 샌드 아스팔트 혼합물의 역학적 특성시험을 수행하였다. 아스팔트 바인더의 물리적 특성으로 절대점도, 동점도, 침입도 시험을 수행하였고 바인더의 PG등급을 결정하기 위하여 DSR시험과 BBR시험을 수행하였다. 직접인장시험과 간접인장시험으로 아스팔트 혼합물의 역학적 특성을 측정하였고, 회귀분석을 통하여 바인더의 물리적 특성을 근거하여 샌드아스팔트 혼합물의 인장강도를 예측하기 위한 모델을 개발하였다. 이로부터 물리적 특성과 직접인장강도 사이의 밀접한 상광관계가 있음을 구명하였다. Asphalt concrete is a mixed product f asphalt binder and aggregates. Characteristics of asphalt mixture are changed with variation of binder's rheology. Therefore, the asphalt is modified using many polymers to obtain a better rheological properties. mechanical property of asphalt concrete is also a function of binder characteristics. However, the correlation of asphalt property with mixture mechanical property is not well known. This study dealt with evaluation of physical properties and PG grade of polymer modified asphalts, and mechanical properties of sand asphalt mixture. The physical property evaluated included absolute viscosity, kinematic viscosity, penetration. DSR and BBR test was performed to obtain appropriate PG grade. the mechanical property included indirect tensile strength and direct tensile strength. Regression analysis was carried out to obtain a prediction model form tensile strength of sand asphalt mixture based on physical property of binder. A relatively high correlation was sound from each physical property with direct tensile strength.

최근 우리 나라의 여러 작물에서 뿌리혹병(根頭癌腫病, crown gall)의 발생이 증가하고 있음이 보고되고 있으며, 특히 중요한 화훼작물인 장미를 재배하는 시설하우스에서 뿌리혹병의 발생은 매우 심한 피해를 가져오고 있다. 그럼에도 불구하고 이 병에 대한 방제는 거의 이루어지지 않고 있는 실정이다. 본 연구에는 전 세계적으로 매우 성공적으로 뿌리혹병의 생물농약으로 개발된 Agrobacterium radiobacter K84의 장미 뿌리혹병 방제효과를 검정하여 국내에서 장미 뿌리혹병의 방제에 그 사용가능성을 확인하고자 하였다, 장미의 지상부에 인위적인 상처를 주고 병원균을 접종하기 전에 그리고 접종후 A. radiobacter K84 균주 현탁액의 살포는 뿌리혹병의 발병율과 혹의 크기를 크게 감소시켰다. K84균주를 처리한 장미에서 뿌리혹병의 발병율은 5.0 - 6.7%로서 병원균을 단독 접종한 대조구에서의 발병율 85% 비하여 크게 낮았다. K84 균주를 처리한 장미에서 형성된 혹의 크기와 생체중도 병원균만을 접종한 대조구 장미에 형성된 혹은 4-5%로서 K84균주의 처리에 의해 크게 감소하였다. 장미의 뿌리에 인위적인 상처를 주고 병원균의 접종 전 및 후에 K84 현탁액에 침지 처리한 처리에 의해서도 혹의 크기, 생체중, 그리고 병발생율이 크게 감소하였다. 전체적으로 K84균주 처리에 의한 지상부 혹의 생물적방제가는 92-94%이었고, 뿌리에서의 뿌리혹병 생물적방제가는 51-59%이었다. 이상의 결과는 A. radiobacter K84균주의 처리가 매우 효과적으로 장미 뿌리혹병을 방제할 수 있음을 보여주고 있다. Servere crown gall disease was occurred in green house cultivating rose in Jinchen, Chungbuk recently. Although it causes problem on rose cultivation, the growers do not have many choices of control measures for the disease now. A. radiobacter K84 has been known as a strong antagonist against A. tumefaciens, a pathogen causing crown gall disease and used as a biopesticide for crown gall in many countries since it had been introduced in 1972. We tested control ability of A. radiobacter K84 for the crown gall disease on rose. Spray of A. radiobacter K84 suspension on above ground of rose either before of after pathogen spray reduced size and fresh weight of galls significantly. Size and fresh weight of galls on roses inoculated with pathogen either before A. radiobacter K84 spray (pathogen-K84 treatment) or after A. radiobacter K84 spray (K84-pathogen treatment) were 4 to 5% of those of galls on roses inoculated pathogen only. Diseased rate of plants inoculated pathogen only was 85% whereas diseased rates of pathogen-K84 or K84-pathogen treatments were 6.7% and 5.0% respectively. Dipping of roots of rose in suspension of A. radiobacter K84 was also reduced size of galls and diseased rate significantly. These results indicate that A. radiobacter K84 is effective in the prevention of gall formation by A. tumefaciens and it can be used to control of crown gall disease of rose.
박광순 건국대학교 1995 대학원 학술논문집 Vol.42 No.-
Last year, Korea's total trade deficit recorded 6.3 billion dollars. Meanwhile the trade deficit of general machineries, which is called the capital goods in a narrow sense, recorded 9.9 bilion dollars. Therefore it is indispensable to solve the problems not by private company base, but by the Korean government. And it is a structural problem that better economic situations lead to great-er imposrt of capital goods. Meanwhile Japan and Germany's capital goods industries are very competitive and the solid trade structures of the above-mentioned are sources of the national trade black figures. It means that the development of capital goods' industry is indispensable for a nation's competi-tiveness. The establishment of capital goods' development strategy by the Korean government ( 1995. 5. 10 ) was done due to the importance of the above-mentioned industry, and many companies ( 82.2% ) have positive view regarding the strategy. However there are some differences of evaluation according to the detailed policies and the company size. Some problems such as the financing bias of machinery purchasing fund, the ef-fectiveness of newly planned quality mark system, and the excessively wide scope of capital goods should be solved in advance. From this point of view, the development strategy can be more effective through the following resolutions. 1.Compulsory share of machinery purchasing fund for small and medium sized companies. 2.Increase of machinery development fund 3.Establishment of long term and consistent development strategy. 4.Amendment and establishment of political financing system, which is allowed in the WTO system.

Objectives: Epstein-Barr virus (EBV) has been known to be linked to a spectrum of neoplastic conditions, including nasopharyngeal carcinoma, Burkitt's lymphoma, peripheral T-cell lymphoma and Hodgkin's disease. This study aims to investigate the association of EBV with gastric carcinoma in Korea. Methods: Fifty-three cases of gastric adenocarcinoma were studied for evidence of EBV infection by EBV-encoded small RNA (EBER) in situ hybridization (ISH) on the paraffin sections and amplifying the EBV genome encoding envelop glycoprotein (gp220) with polymerase chain reaction (PCR) in fresh gastric cancer specimens. Results: EBER was detected in 7 (13.2%) of 53 gastric carcinomas and all cases were male. In 6 (85.7%) of 7 EBER-positive cases, the tumors were located in the upper and middle part of the stomach. EBER ISH study showed strong positivity in all the tumor cells, but negativity in surrouning lymphocytes, stromal cells and normal gastric mucosa. DNA PCR was positive in 23 (43.4%) of 53 gastric carcinomas, including all of 7 EBER-positive cases. Conclusion: We could observe some association of EBV with gastric carcinoma, and our findings about the charateristics of EBV-positive gastric cancers involving sex, site and histological type are similar to those in Japan. However, EBV-positive rate of gastric cancer is higher than in Japan and lower than in Western countries. Further studies to elucidate oncogenic mechanism of EBV in gastric cancer should be performed.
金光淳 慶北大學校 東洋文化硏究所 1977 東洋文化硏究 Vol.4 No.-
Pojulkoonjun(抱節君傳) is a novel of Chinese writing style and the bamboo is personified in it. The writer of this novel is Jung Soo-kang(丁壽崗), his courtesy name Boolboong(不崩), his pen name Wolhun(月軒). He was born in Baik chun-kun(白川郡) on August 26 of the 2nd year of King Dan-jong(端宗), lived through those kings of Seijo(世祖), Yeajong(睿宗), Sungjong(成宗), Yeonsankun(燕山君) and died in the 22nd Year of Joongjong(中宗) at the age of 74. His Characteristics of personality were diligence and gentleness and from early childhood he was outstanding in literary talent. His career is divided into five periods. It is revealed that this division is consistent with the development of Pojulkoonjun when we compare these two. Therefore Pojulkoonjun is a latent allegory of the life history of Jung Soo-kang himself. Here I clarified this novel is the chronic record of the events which happened in Kojookkun's(孤竹君) life who is a proxy of Wolhun. Pojulkoonjun is a personification novel of the former Josun Period which followed the literary form of personification novel and it is evaluated as very important. In this thesis I pointed out the present prevailing view that the literary form of personification during the later period of Koryu declined into trivial thing is quite wrong. Also I proved it clear that the literaly form of personification in Josun Dynasty Pojulkoonjun, Hyunjukjun(硯滴博), Sisejun(施賽傳) belongs to that literary form. Another point I asserted here is the literary form developed to an advanced form of the novel under the influence of the novel of that period and Chunkunyeoney(天君演義), Chunkunbonki(天君本記), Soosungyi(愁城誌) belong to this advanced form. Like this, in the history of Korean novel development, Pojulkoonjun has the great significance that in Josun Dynasty played the medium role to follow and develop the literary form personification during the later Koryu period.

Leakage studies have been performed frequently, since a fluid-tight seal provided by various dental filling materials has been considered clinically important. The leakage of the various root-end filling materials has been widely investigated mostly dye penetration method. These dye studies cannot offer any information about the quality of the seal of a test material over a long period of time The purpose of this study was to evaluate the microleakage of root end cavities in blood contamination filled amalgam, intermediate restorative material(IRM), light cured glass ionomer cement(GI) and mineral trioxide aggregate(MTA) by means of a modified fluid transport model. Fifty standard human root sections, each 5mm high and with a central pulp lumen of 3mm in diameter, were and filled with our commonly used or potential root end filling materials after they were contaminated with blood. At 24h, 72h, 1, 2, 4, 8, and 12 weeks after filling, leakage along these filling materials was determined under a low pressure of 10KPa(0.1atm) using a fluid transport model. The results were as follows: 1. MTA group showed a tendency of decreasing percent of gross leakage(20ml/day) in process of time, whereas the other materials showed a tendency of increasing in the process time. 2. At the all time interval. GI group leaked significantly less than amalgam group and IRM group (p<0.05). 3. At the 4 weeks, the percentage of gross leakage in MTA group decreased to 0% thereafter, the low percentage of gross leakage was maintained in MTA group until the end of the experiment, whereas the percentage in IRM group increased to 100%. 4. At the 12 weeks, percentage of gross leakage was significantly low in MTA group(0%), comparison with GI group(40%), amalgam group(90%) and IRM group(100%), but there was no significant difference between latter two materials.
