High serum cholesterol concentration are associated with the coronary heart disease, which is the major cause of death in the world. The consumption of milk products containing lactobacilli or bifidobacteria are known to have a serum cholesterol-lowering effects in human, swine, and rats. Recently, bile salt decongugation has been proposed as the cause of hypocholesterolemic activity of lactic acid bacteria. Since conjugated bile acids are necessary to emulsify cholesterol in small intestine, bile salt deconjugation by lactic acid bacteria could decrease intestinal absorption of cholesterol. Free bile acids as well as cholesterol are less soluble than the conjugated bile acid at intestinal pH(pH 5.5~6.5). Therefore, lesser amount of free bile acids and cholesterol are absorbed through the enterohepatic circulation and lots of them are absorbed through the enterohepatic circulation and lots of them are excreted via feces. Thus, serum cholesterol could be removed from the body's pool. Because L. acidophilus strains tend to exhibit host specificity, the most effective strains as dietary adjuncts for human to aid serum cholesterol control should be originated from human intestinal environment. The fermented milk made by using lactobacilli of higher bile salt deconjugation activity is proved to act as better hypocholesterolemic lactobacilli.

Osteosarcoma is a primary malignant tumor arising most often in the long bone, but rare in jaw bone. Especially osteogenic sarcoma of the mandible is a rare tumor, comprising less than 0.5% of all head and neck tumors. Osteosarcoma occurs cheifly in young persons, and presenting very survival rates. Histopathologically this tumor can be classified three types, osteoblastic, fibroblastic, chondroblastic and classified from low grade to high grade by anaplasia or mitosis of the tumor cells. Sometimes, the exact diagnosis of osteosarcoma is difficult especially in low grade osteosarcoma, even if clinical or radiographical findings suggest to osteosarcoma. So suspcious to malignant bone tumor in clinical or radiological findings, biopsy should be taked from deep portion and multiple area, and sharing the patient history and radiographs with pathologist will assist in the development of the diagnosis. We report a case of low grade osteosarcoma on the mandible initially difficulty in accurate diagnosis. The patient visited our hospital for routine dental treatment but radiographic findings displayed ill-defined radiolucency with osteoid formation on the mandible. Final diagnosis was difficulty in initial biopsy but subsequent biopsy taked from deep portion presented infiltrative growth and mitosis of the tumor cell in some area with small osteoid bone formation, so we could reach final diagnosis as low grade sarcoma. We treated this patient with bloc resection of the mandible and immediate reconstruction with iliac corticocancellous block.

소련의 外交政策事例 硏究 : 「오스트리아」政策을 中心으로 with Special reference to the Austrian Policy

金顯煜 단국대학교 1977 論文集 Vol.11 No.-

The negotiations over the State Treaty had more or less been ata standstill from the end of 1949 to the beginning of 1954. Through constantly new demands that had little or nothing to do with the re-establishment of Austira as an independent state, the Soviet Union sought to delay an agreement by any means. At the Berlin Conference in the beginning of 1954, the Soviet Union had been prepared to sign a State Treaty but at the same time refused to evacuate Austria before the conclusion of a peace treaty with Germany. The Soviet Foreign policy had changed, although not the regime itself. The main reason was that the Soviet Union had been confonted with many complicated problems-exterior as well as interior-which it had been unable to solve. Thr rulers in the Kremlin were now interested in a general relaxation of the pressure to which they had been subjected by the Western powers. They needed peace amd quiet for some time in order to reduce the burden of their armaments and to deal with China, with the shortcomings of their agricultural production, and many other complicated problems. According to John Foster Dulles, this had been the main reason for the final Soviet consent to the State Treaty and the evacuation of Austria. The relaxation was not a goal for the achievement of which the Soviets were willing to pay a price. From their point of view it was only a means by which they hoped ti undermine the resistance of the Western powers to their own demands and thereby pave the way for the attainmennt of their main objectives in Europe: 1) the consolidation of use Soviet territorial gains after World War Ⅱ ; 2) American withdrawal from Europe, thus fatally destroying the Western political and military alliance ; 3) the prevention of a strong united Germany, integrated with the West, a result which in its turn, was a necessary prerequisite for the integration of West Germany in tthe Eastern bloc some time in the future. Soviet expansion after the war had frightened the Western powers and strengtehened and fortified their unity. The North Atlantic Pact had been sighed ; the rearmament of the non-Communist part of Europe accelerated. Finally a West German state had been established which claimed to represent all Germany. As it soon became clear that the defense of the NATO states was almost hopeless without German cooperation, negotiations had been initiated on ways and means to render the rearmament of the Federal Republic of Germany possible. The first indication of a change in Soviet Policy toward Austria did not come until the beginning of February 1955. At the end of the previous year the French National Assembly had approved the Paris agreements on the rearmament of West Germany which had replaced the treaty on the European Defense Community, rejected by the assembly on August 30, 1954. There was a widespread opinion in the West that the main reason the Soviets had finally accepted the State treaty was to create a model for a subsequent solution of the problem of German reunification. Khrushchev held that the strengthening of the Federal Republic by a close political and economic collaboration with Austria ciould, as the Swiss example proved, just as well be effectively prevented by an Austrian declaration of perpetual neutrality. From the Soviet point of view neutrality. Consequently, was a political means by which not only the weakening and final disintegration of NATO and other similar organizations should be hastened, but also, it was hoped Austria should be prevented from a closer political and economic association with the Federal Republic whose influence within the Western bloc, it was feared, would grow more and more as years passed.

The rapid growth of the network-systems with internet’s development overcomes the differences between the time and the distance. Also The development of the Hacking technique is threatening the environment of the network-system severely. In this paper, I grasped the situation of that first, and designed the systems to collect their attack information on the basis of the Linux on the network. It was designed the host system in general and laid out the firewall, router and the Linux-systems not to miss the procedure of the invader’s succeeding in attack and it was described to prevent the abuse from the data-controlling point of view.

고전적 순막 조건화 동안의 해마 뇌전도와 다단위 활동

해마에서만 발견되는 뇌전도는 낮은 주파수, 높은 진폭의 특징을 갖고 동기화가 잘 이루어져 마치 정현파에 가까운 형태를 보인다. 이러한 뇌전도에 대해 서파리듬 또는 θ파라 부르고 전기 생리학적인 연구가 많이 진행되고 있다. θ파의 주파수 특성, 발생기전, 행동과의 관련성 등에 대해 집중적 연구가 이루어졌고, 그러한 연구를 기초로 θ파의 기능에 관한 여러가설이 도출되었다. 본 연구에서는 이러한 해마의 서파리듬이 행동과 어떤 관계를 갖고 있는지를 알아보기 위하여 토끼의 순막반응을 고전적으로 조건화시키는 동안에 미리 해마에 삽입한 전극으로부터 뇌전도와 다단위활동을 기록하였다. 해마 서파리듬에 대해서는 주파수 분석을 실시하고 다단위 활동은 시간단위당 발화 횟수를 측정하여 조건화과정과의 관련성을 살펴보았다. 실험 결과, 해마의 다단위 활동은 순막의 조건 반응과 높은 상관관계를 보여주었다. 해마 서파리듬은 조건화 절차와 관계없이 조건자극, 무조건자극 제시 기간에 제2유형인 4,5㎐의 감소와 제1유형인 7,8㎐의 증가를 보였다. 이는 해마 서파리듬의 기능이 조건화된 반응보다는 조건자극과 무조건자극의 제시와 관련이 있음을 시사하는 것이었다. 이러한 결과를 해마 θ파의 기능에 관한 여러 가설에 비추어 논의하였다. This study was investigated to hippocampal θ rhythm and multiple unit response during classical conditioning of rabbit's nictitating membrane response. Hippocampal θ rhythm usually was classified into type 1 and type 2. According to various electrophysiological researches, type 1 θ rhythm was highly correlated with voluntary behavior and type 2 θ rhythm with automatic behavior, but there were studies which assert that type 1 θ rhythm was correlated with sensory information processing. So, this study was an attempt to investigate those results as compared paired conditioning group with unpaired control group. Paired group was presented 500msec tone CS followed 100msec air puff US after 400msec interstimulus interval. But unpaired group was presented 500msec tone and 100msec air puff independently. There was no difference in distinction of θ rhythm between the two group. Again, there was no correlation between θ rhythm and conditioned response. But, there was high correlation between multiple unit response and conditioned response. The result indicated that type 1 θ rhythm was highly correlated with presentation of tone and air puff in both group, this result suggest that type 1 θ rhythm is correlated with subject's information processing.

日本語의 形容動詞 硏究

宋賢穆,李相旭 대구산업정보대학 1992 논문집 Vol.6 No.-

In Japanese, Attributive Verb that had first been used by Ootsuki in 1897 was to avoid confusion in between it in Japanese and adjective in English. Namely, Dr.Hasimoto acknowledged it to be a independent word class. Attributive Verb that has many questions among Japanese word class has been attacked for a long time. The main cause of attack is that it is received either one word or two word. Particularly, we can say that Dr.Tokieda is representative of negatory theory. We can look upon the stem of a word as one word in that Attributive Verb has a stem which an independent nature is strong and a stem is only found in a dictionary. Therefore, Attributive Verb which we consider as to word in common is correct. In this thesis, I look into Attributive Verb that is in the same manner found in a dictionary and intend to revise a conception through the analysis of a original language. In the result, I think that it should not be independent as a word class.

<千金要方>에 記載된 <傷寒論>의 考察

孔兌旭,嚴賢燮 동의대학교 한의학연구소 1998 동의한의연구 Vol.2 No.-

This study is to compare the text of Sanghan(傷寒)'s section (9 and 10th volume) in Chungumyobang(千金要方) with the text of Sanghanron(傷寒論). The conclusion obtained as follows; 1. Sanghan(傷寒) of Chungumyobang(千金要方) is made up of 201 prescription and 43 symptoms and Sanghanron(傷寒論) is composed of 113 prescription and 398 text. 58 text and 22 prescription in Sanghanron(傷寒論) is found at contents of Chungumyobang(千金要方). 2. The three puts of Sanghanron(傷寒論)-Byunsoyangbyungmaekjungbyungchi(少陽病脈證幷治), Byuntaeeumbyungmaekjungbyungchi(辨太陰病脈證幷治) and Byungwaknan byungmaekjungbyungchi(辨證亂病脈證幷治)- were not found at Chungumyobang(千金要方). 3. Chungumyobang(千金要方) used different name as compared with Sanghanron(傷寒論). For example, Gejitang(桂柱湯) is Yangdantang(陽且湯) at Guemgueyoyak(金??要略), Sosihotang(小柴胡湯) is Hwangryongtang(黃龍湯), Hyunmutang(玄武湯) is Jinmutang(眞武湯). 4. Due to different number of text and content of composition, can infer that Sonsamak(孫思邈), the writer of Chungumyobang(千金要方), didn't read Sanghanron(傷寒論) when he edit his book. 5. With Chungumikbang(千金要方), Chungumyobang(千金要方) is a very important literary work that collect and adjust Sanghanron(傷寒論) or Wangsukhwa(王叔和). Chungumyobang(千金要方), rare material, is help to suppose and make a study of the original of Sanghanron(傷寒論).
