Whether a ship is sub-standard or not shall be finally decided by the minimum standards laid down in international conventions or national standards having the same effects. The flag State is primarily responsible for implementing these standards as far as its own ships are concerned. And the port State shall, in the exercise of its rights under international law, take appropriate measures (including detention of ships identified as sub-standard), which are regarded as port State's supplementary role aiming at implementing these standards. The international standards are implemented by the regional co-operation in the form of the MOU(Memorandum of Understanding) on Port State Control in the Asia-Pacific Region on the ground that the PSC enforcement of only one country does not enable the eradication of sub-standard ships. Recently, EQUASIS which is an international database covering the whole world fleet change the regionalism of PSC into the globalization of PSC. However, there are many problems in Tokyo MOV and Korean PSC regime. In order to ensure the implementation of the standards laid down in international conventions and Tokyo MOU, the Korean and other country in Asia-Pacific shall settle the alienation from the actuality of the law, namely the problem of maritime administrative structure of non unifying PSC affairs.

양산단층이 지나는 한국 남동지방 지각의 QP-1 및 QS-1를 한국자원연구소가 설치한 9점의 지진관측소 자료를 바탕으로 확장 Coda 규격화법을 이용하여 구하였다 1994년 12월부터 2000년 2월에 일어난 근지지진에서 707개 지진기록에 대하여 1∼2, 2∼4, 4∼8, 8∼16및 16∼32Hz의 대역필터를 적용하여 분석한 결과, 각 관측점의 QP-1는 (7±2)×10-3에서 (5±4)×10-4으로, QS-1는 5±4)×10-4에서 (5±2)×10-4로 주파수가 1.5Hz에서 24Hz로 늘어남에 따라 줄어드는 주파수 의존성이 보인다. 이들 값의 지수 회귀선은 QP-1가 0.009(±0.003)f-1.05(±0.14), QS-1가 0.004(±0.001)f-0.75(±0.14))이다.

In order to Investigate water tree degradation behavior on XLPE cable, direct voltage of 200 to 800V has been applied to the material at 50℃~100℃, and the water tree property has been correlated with voltage and temperature. The leakage current was increase as temperature increased and the Ohm's law was generally satisfied in this experiment though some experimental errors were found. The leakage current was decreased and reached to the stable state with time. It was also shown that the time for the stabilization of leakage current was lessened as voltage increased

Since the introduction of product liability law from America in 1960s, product liability has been on the rise as an important problem to the quality management of company and consumer's safety. Together with this, before the legislation of product liability system in Korea, the sense and level of company and consumer about product safety are rapidly changing, In times like the present, ensuring more systematic product safety and consumer safety, and the buildup need of competitive power in accordance with product liability prevention of company grows raising. Therefore, this study presents the most effectively manageable ways of product liability the side of safety management of consumers and companies through the ensuring ways and activity models of product safety and certification system in company.

For long times I, the author, wanted to find the materials of language and literal policy during the American military administrative era, but it would not go easy. Then in 1999 Mr. Son, WonIl, my acquaintance found and send me 『Report of the United States Educational Mission to Japans』. This working is written for analyzing our country`s language policy right after Liberation, and its background, focusing on 『Report of the United States Educational Mission to Japan』, and for trying to find out alternative policy. Now over half a century have passed since the Liberation, but where we stand on the great wave of world history? Our language & literal policy have repeated twisted walking tending to the emotional surroundings that based on Hangul-only ism since the enactment of Hangul-only-law in October, 9, 1948. Language & literal policy does not, reveal visible result to our eyes immediately as industrial one. But the result of language policy make enormous influence enough to tremble the identity of a nation. Nevertheless I could not find any traces of policy authorities that took attention on this problem, at any successive governments. The two voices that proclaim Hanja-education and Hangul-only-education have too acutely confronted, so each have run parallel way with no yielding. The scholars and policy authorities that do not join any of the two sides have disregarded the two voices as obstinate egoistic quarrel of some scholars that have nothing to do with them. The proclamations of scholars whether in Hanja-education or Hangul-only-education also in fact flowed mainly as a matter of course that `must educate Hanja` or `must use Hangul-only`, not by rational analyzing of the cause and proposal of logical alternatives. But the causeless and emotional matter of course will not be persuasive. There were exceptional excellent work such as quot;Collection of Lectures on National Language and National Alphabetsquot; of Dr. Nam, GwangWoo and quot;The Significant Misunderstanding about National Languagequot; of Mr. O, JiHo. But the works that mainly on analyzing and alternatives are very uneasy to find out. During last several years I, the author, writing works concerning language & literal police become to observe Korean language at linguistic side. The more I investigate Korean language, the more I perceive that Hangul and Hanja are undividable linguistic features. Of course since I am not a linguistics specialist I feel sorry for the specialized scholars. But the books of Mizura Sdomu, who not a scholar of linguistics, that studied linguistic features of Japanese language more deeply than any other and left distinct footsteps on that field, gave me many stimuli. The keen analyze of Mr. Park KyungBeom, a natural scientist graduated the department of computer science and statistics of Seoul National University, also be a great help to compare and analyzing the linguistic features of Korean language and English language. Recently many people says quot;The crisis of human sciencesquot;, but few accurately point the cause of that. Boldly I think the cause is at the wrong Hangul-only language & literal policy. Although language & literal policy is a significant and great affair that holds the destiny of national people, it have been disregarded as out of consideration. Hangul-only policy of the character media such as newspapers and editions have made the thinking of readers dull, voluntarily result in shackle themselves in competition with television media. This rough work is not a pure academic one that comments the linguistic feature of Korean language. Only I will be satisfied if throughout this work, we can reflect the problems of our history of language and literal policy and can find out even a small motive for studying linguistics of Korean language.

귤응애의 예찰방법을 개발하기 위하여 제주지역의 온주밀감원에서 귤응애 분산형태에 대해 2개년(1999~2000년)에 걸쳐 잎 표본에 대하여 각 조사일에 평균밀도를 조사하였다. Taylor's power law와 Iwao's patchiness regression을 이용하여 분산지수를 비교하였으며, 잎 표본 조사에서는 일반적으로 Taylor's power law가 Iwao's patchiness regression보다 평균-분산 관계를 더 잘 나타내었다. Taylor's power law의 기울기와 절편은 조사한 포장 간에 차이가 없었으며, 여기에서 얻어진 상수값을 이용하여 잎 표본 조사에 의한 귤응애 약 .성충에 대한 고정정확도수준에서의 표본조사법을 개발하였다. 이 조사법에 대해 resampling 기법을 이용하여 독립된 4개의 조사자료를 이용하여 분석한 결과 실질 고정정확도(D)값이 요구되는 D값보다 항상 낮았으며, 나무당 귤응애 밀도가 8마리 이상에서 필요한 조사 나무수는 18주보다 작았다.
