In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Korea was released from the Japanese colony by the help outside. So, we experienced the tragedy of fractricidal was called 6.25. This war which brocked out in our country is extraordinary as compared with orther wars in the history of the world, accordingly the war is different in many sides. For this reason, a rigid experience of 6.25 war became a literary proposition in our literary stage. The cardinal point of Korean literature in divided situations adopted two intensive propositions; the first proposition is to pursue the same nature of our people and the other is to overcome the problem of a divided situation in our country. But postwar generation present a marked contrast to the prewar generation in their sence. The former idiologically objectifies the situation of society, while the latter subjectifies the situation of cruel historic experience. Consequently, on the ground of the fusion of both sides, we must develope the quality of Korean literature considering divided situations. That must be neither a simple arrangement of the experience of war, nor an impatiently integrated argument. Korean literature considering the divided situation must be a literature illustration of the future which contains the Korean unification of spirit and nationalism.

辛 夕汀 詩의 位相 : 初期詩를 中心으로 Centered on His Early Poems

許衡錫 群山大學校 1984 論文集 Vol.9 No.-

This is a study on Shin Sok-Jong's early poetry. While some researches have been made about Shin Sok-Jong's early poetry, most of them concluded that in evaded the real life as a pastoral poet. However, a closer observation shows us that the trend depends on the general human mind craving for Utopia. In other word, this is a kind of libidinal mind to try to transcend. His early poems unfold the idealistic world free from any interference, with the result that they win the effects of raising the resistance to the real life suffering from the environment. Therefore, his Utopian world is not the one for only his own comfort without any relationship to the real life, but it is the world where his Utopia can join the cammon life in the joint consciousness. The errors which result from misunderstanding Sok-Jong's early poems interfere with the discussion of the latter poems. In this paper I don't place Sok-Jong's early poems within the limit of the pastoral life, but I try to pay attention to the point that the early poems had the strong history consciousness of the latter poems made. To conclude, it is emphasized that Sok-Jong was not a poet who avoided the dark historical situation under the rule of the Japanese, but he was a poet poured out his sad mind through lyrics. Consequently, he is thought to remain a rarely indigenous poet in the history of the contemporary Korean Poetry.

쌀, 옥수수에 대한 솔잎 Polyphenols 처리가 Aflatoxin 생성 저해에 미치는 영향

김형열,윤원호,구본순 한국식품저장유통학회(구 한국농산물저장유통학회) 2002 한국식품저장유통학회지 Vol.9 No.1

쌀과 옥수수를 온습도의 조절 없이 상온에서 90일간 장기저장하며 aflatoxin 생성 정도를 측정해 본 결과 쌀과 옥수수에서 공통적으로 저장 30일 이후 각각 0.1, 0.3 ppb의 aflatoxin이 검출되었다. 그러나 저장 온도 및 습도가 상승할수록 aflatoxin 생성 정도는 비례적으로 급속한 증가추세를 나타내어 이들 시료에서 aflatoxin 생성 최적 온습도는 각각 25∼30℃, 80% 내외인 것으로 밝혀졌으며, 동일한 조건하에서 상대적으로 쌀보다는 옥수수에서 그 생성 정도가 심각함을 확인할 수 있었다. 한편, aflatoxin 생성 최적조건인 온도 30℃, 습도 80%의 조건하에서 쌀과 옥수수에 대하여 MeOH 추출물과 polyphenol성 물질들을 각각 0∼0.05% (w/w) 단독처리하여 저장기간에 다른 aflatoxin의 생성량을 측정한 결과는 다음과 같았다. 즉, 전체적으로 그 처리량이 증가할수록 상대적으로 aflatoxin 억제능은 상승하는 것으로 나타났으며, 종류별로는 catechin (CT) < MeOH extract <polyphenol(PP) < flavonoid (FN)의 순으로 나타났다. While rice and corn were stored at room temperature for 90 days the degree of aflatoxin production was measured without humidity and temperature control. The amount of aflatoxin production of rice and corn after 30 days was 0.1 and 0.3 ppb, respectively. The degree of aflatoxin production increased rapidly with increasing storage temperature and humidity. The optimum conditions of aflatoxin production were 25∼30℃ and 80% humidity. The degree of aflatoxin production in corn was higher than in rice under the same conditions. Rice and corn were treated with 0∼0.05%(w/w) of methyl alcohol (MeOH) extract and polyphenol (PP) group materials individualy respectively under the optimum conditions. As the result, the inhibition effect of aflatoxin production increased with increasing the amount of treatment. It appeared as follows: catechin (CT) < MeOH extract < PP < flavonoid (FN).

All ships require to be controllable in directional in the horizontal plane so that they can proceed on a straight path, turn or take other avoding action as may be dictate by the operation situation. So it is very important for a navigator on bridge to know the manoeuvrability of ship sufficiently at sea. It is not easy to define ship's manoeuvring chracterities perfectly because the manoeuvrability is connected with hydrostatic forces over ship's body. But, as a number of manoeuvres are commonly carried out by ship's steering, it is necessary for a ship to hold how about the ship's trial measurement of manoeuvrability by steering. The results obtained are summaried as follows; 1. The turning circle trial test is not only a standard maneuver test carried out all ships as indication of the efficiency of the rudder, but also the datas of pivoting point, drift angle and steady turning radius have been used to gain room inter-ships. 2. As the Zig-Zag manoeuvre trial test is carried out to study more closely the initial response of a ship to rudder movements, the values of manoeuvring indices, K and T, give an information for preventing collisions at close quarters situation. 3. According the spiral manoeuvre trial test provides an indication of a ship's directional stability or instability for all rudder angle, the steady rate of change of heading by it's trial test can be used to alter or maintain course.

開發途上國에 있어서의 多國籍企業에 관한 硏究

朴炯昊 全南大學校企業經營硏究所 1974 産業經濟硏究 Vol.1 No.1

The term “Multinational Coporation, ”a product of the 20th century, has been popularized in recent years, but that type of enterprise was already begun in the 1870s. In general, the developing countries want to develop their economy, but they are lacking in capital, technology, management skills, etc. On the other hand, the MC seeks for the maximization of profits with sufficient capital, advanced technology and management skills. Under the circumstances, the DCs and the MC can help each other for the mutual advantages. If so, the MC is bound to transfer its capital, technology, and management skills to the DCs and helps to make them develop the undeveloped economy. The MC engages in various international activities and operates plant in a number of countries with different political, economic, and cultural environments; it has a substantial financial commitment overseas and derives considerable profits from this business; and it has a worldwide perspective in marketing, investments, and other opportunies. It is natural that the investment effects of the MC should depend on the policies of host country and, in the end, upon all the negotiation abilities of both sides. Taking into consideration the investment motives and the nature of capital, the disadvantages of the MC on the DCs may be inevitable. Nevertheless, the host country should try to take measures in order to reduce those harms as far as possible. The first thing to be considered is to fortify its ability to absorb the foreign direct investment. And then, the MC ought to be advised to take self-restriction. In case this self-control is not effective, the host country can take the following restrictions; the determination of specific investment scope and definite investment ratios, management participation, the adoption of shrinking tariff system and “Calvo” clause, and so forth. Thirdly,, it is quite desirable that the host country makes an agreement, like GATT or IMF, with the investing country on a national basis. The agreement is related to the restriction of the MC activities which might hurt the economic and political sovereignty of the host country. In addition, we can consider the transnational international institution. But, in the near future, it seems to be difficult to expect its establishment. That is the reason why the world economy has not yet become a perfect economic community and each nation-state has not yet developed into a simple international nation institution. Those various restrictions might make the MC inactive temporarily and, in the long run, it will play the greater part in the world economy and, especially, in the DCs owing to its necessity and growth tendency. The MC will ultimately evolve into the “Transnational Enterprise” and, futhermore, the 21th century will be called “the century of the MC.”

해를 거듭할수록 심각성이 더해가는 어업자원의 고갈과 이에 따른 어업자원 관리대책의 수립은 잠재 어족생물 자원량 분포의 정확한 평가가 선행되어져야 함은 주지의 사실이다. 이러한 관점에서 어족자원 정도개선을 위한 연구의 일환으로, 개량어탐시스템의 계측알고리즘을 바탕으로 최근 활용단계에 이르고 있는 2단계 적분방식과 기존 적분방식을 비교 검토한 결과 2단계 적분방식의 장점을 요약하면 다음과 같다. (1) 파라메타 설정이 용이하여 THRESHOLD처리에 따른 오차를 줄일 수 있다. (2) 자원량 추정에 필요한 어족생물만의 선별처리가 가능하므로 오차를 줄일 수 있다. (3) 평균SN비가 양호하다 (4) 선별에 의한 어족 생물의 상세한 정보를 얻을 수 있다. (5) 1단계 적분결과에 대한 후처리가 가능하다. 이상의 결과에서 2단계 적분방식이 어족자원의 정도 개선면에서 뿐만아니라 상세한 정보처리의 능력면에서 기존의 적분방식보다 양호함을 나타내고 있음을 알 수 있는데, 아직 미진한 부분도 없지않다. 즉, 2단계 적분방식에서는 일단계 적분이 되어진 Main windows상에서 선별에 의한 2단계 적분을 행함으로서 기존의 적분방식보다 복잡한 양상을 보임에 따라 고도의 전자기술 응용과 자동처리에 적합한 소프트웨어의 개발에 대한 지속적인 연구가 요망 되어진다. Echo integration if indispensable in an acoustic survey for assessing fish abundance. The reason is that it is required for computing integrator measurement of fish density in terms of numbers. Two-step integration method is offered as a new way for the accurate estimation of fish abundance. The conventional echo integration method is examined theoretically and practically to reveal the problems inherent in the method. It is shown that the errors caused by noise and unamied scatterers are apt to be large and selection of aimed fish echoes is difficult. These shortcomings are resolved by appling the two-step echo integration method, which first integrates echoes in small cells and then integration weighted results of the first integration in a large cell. Two-step integration method represents a great improvement compared with former method used in fisheries research. The results obtained can be summarized as follows: 1. It is reduce errors by processing the threshold because two-step integration method has processed to alternative parameter setting. 2. Two-step integration method integrates based on the selected fish echoes so that the noise and unamied scatters can be removed from fish abundance. 3. Two-step integration method could be improved the lower signal to noise ration that appears in the echo integration. 4. By selection of only the need part. One can be observe detailed information on fishes. 5. It sould be capable of dealing with the postprocessing on the results of first intergation.
