월성 원자력 발전소 주변해역에 대한 장기간 수온관측을 실시하여, 수온의 장기간 변화양상, 수평 수온분포 및 연직 수온분포 특성을 분석하였다. 관측기간은 1996년 11월 10일부터 1997년 8월 22일까지 약 280 일간이며, 발전소 인근 10 개 정점에 표층 수온관측기를 설치하고 10 분 간격으로 표층수온의 연속관측을 실시하였다. 또한, 수온의 연직구조를 파악하기 위하여 배수구 인근 2 개 정점에 수심별 수온관측기를 계류하여 20 분 간격으로 표층으로부터 수심 10 m까지 1 m 간격으로 수온을 측정하였다. 관측정점들에 대한 월평균수온의 최저치는 2월의 $12.8^{\circ}C$ 였으며, 최고치는 8월의 $19.6^{\circ}C$였다. 6월~8월에는 냉수가 관측해역에 수시로 출현하는 것으로 관측되었다. 표층수온의 일평균 분포에 따르면, 발전소 미가동 시기였던 1996년 11월과 대조적으로, 발전소 가동이 재개된 1996년 12월 이후에는 발전소 배수구를 중심으로 고수온 영역이 항상 존재했다. 매 시간별 수평 수온분포를 분석한 결과, 고온의 해수가 발전소 배수구를 중심으로 반일주기의 남북이동을 하는 것으로 관측되었으며, 매 시간별 연직 수온분포에서도 표층에 반일주기의 고온수가 나타나는 것으로 조사되었다. 스펙트럼 분석결과, 1997년 2~4월의 경우 발전소 배수구에 가까운 정점들에서 반일주기 성분이 우세하게 관측되었으며, 이는 반일주기 조류에 의해 온배수가 이동, 확산된 결과로 해석된다. 1997년 8원에는 발전소 배수구에 가정 가까운 정점 12를 제외한 모든 정점에서 일주기 성분이 우세하게 나타났는데, 이는 온배수에 비해 대양복사에너지가 훨씬 우세하게 작용한 때문으로 사료된다. The long-term observation of temperature in the coastal waters adjacent to the Wolsung Nuclear Power Plant has been carried out from November 10, 1996 to August 22, 1997, for approximately 280 days using a real-time temperature measurement buoy system. The sea-surface temperature was measured at every 10 minute using 10 buoys. The vertical structure of temperature was investigated near the outlet of the plant with two thermistor chains equipped with 10 sensors at 1 m interval The monthly averaged temperature was the lowest with spatial average of $12.8^{\circ}C$ in February and was the highest in August with spatial average of $19.6^{\circ}C$. The extremely low temperature was frequently observed between June and August, which seems to be the consequence of the intrusion of cold water near the southeastern coast of Korea. Distributions of the daily and hourly averaged temperature show that the highest temperature always occurred near the outlet of the plant and the warm-water patch moved along the north-south direction with the semidiurnal period. The semidiurnal fluctuation of temperature was also observed near the surface of the vertical profiles. The spectral analysis of temperature between February and April 1997 shows that the semidiurnal components prevailed near the outlet. It is likely that the semidiurnal components were due to the prevailing semidiurnal tide in this region. In August 1997, the diurnal components were dominant at the surface water of all stations except Station 12, which suggests that the warm water from the outlet of the plant has less effects in summer on the surrounding waters than the strong solar radiation.

Horizontal scale and movement of tidal front zone, front in the western regions of Korea in summer are studied in conjunction with numerical model and NOAH-11 satellite data analysis(AVHRR multi -channel sea surface temperature). In numerical model result, tidal mixing is dominant in the southeast region of Hwanghae, near field of Taean, Kyunggi bay, near field of Jangsan cape, Seoan bay, mid-east Chinese coast. But the results of the NOAH infra-red image analysis show that low surface temperature by tidal mixing is clear in the southeast region of Hwanghae, near field of Taean, near field of Jangsan cape but not in the Kyunggi bay, Seoan bay and mid- east Chinese coast in August and September, temperature gradient of frontal zone in the southwest region of Hwanghae is 0.05°∼0.1℃/㎞ and tidal mixing is dominant in the near field of Maenggal kundo and Hajodo and low surface temperature extends southwesrward. Early in August, west-east front(0.2°∼0.6℃/㎞) on the south region of Jindo moves northward and persists at east half on the joining line of Jindo and Sohuksando late September. The axis of front on the west region of Jindo is northeast~sorthwest early in August and moves westward until late September The tidal mixing in the near field of Jangsan cape is dominant in the region between Jangsan cape and Baengyougdo early in August and between Baengyougdo and Daechungkundo in late September. The axis of front on the west region of Jangsan cape is south-north and its temperature gradient is 0.2°∼0.4℃/㎞.

Sign Method를 이용한 쯔나미파의 모의실험 - 동해에서의 적용 -

정종률,김성대 한국해양학회 1993 韓國海洋學會誌 Vol.28 No.3

To reduce tsunami hazards, it is necessary to develope the methods which can simulate tsunami wave signals of coastal areas. In the present paper, it is attempted t use Sign Method for analyzing and simulating recorded tsunami signals. A tsunami record Y(t) can be represented as the convolution integral of a source evolution function E(t') and a wave propagation function K(t-t') Y(t)=.int. E(t')K(t-t')dt' A source function contains the peculiarities of a tsunami generator. A wave function is a kind of transfer function which contains the characteristics of a wave propagation path. The source functions and the wave function and the wave functions of 9 Korean coast points and 6 Japan coast points are estimated, and the tsunami wave signals are simulated by the convolution integrals of the source functions and the wave functions. According to the results of analysis, the Sign Method is an effective method for simulating tsunami wave signals of Korean coast points which are located far from tsunami source areas. Furthermore, if the source function of a neighboring point ad the wave function of an another tsunami are given, unrecorded tsunami wave also can be estimated.

This research was conducted by the request of the Ministry of Education as a part of $quot;The investigation of the priority (of Oceangraphy field) of the long term education loan project$quot;, which is promoted in order to find the ways) to reinforce the Oceanography education. The first Oceanography department in Korea was established in 1968 at Seoul National University. During the last 20 years, 10 Oceanography departments, 5 ocean engineering departments and 1 ocean development department were established at 8 universities and 4 colleges. However, the education facilities and the quality of education were not sufficiently improved. Furthermore, an Oceanography research vessel was not built for those ocean related departments up to now. The authority of the Ministry of Education, which foresaw the fast-changing marine policy of each nation and the rapid technological advances of ocean development, prepared a plan to search a way to reinforce the college level Oceanography education so as to secure the future survival of this nation. Therefore, through this investigation a reinforce plan of Oceanography education in Korea was formalized.

ESCP 硏究 : 韓國에서의 貢獻 可能性을 中心으로

鄭鍾律 서울대학교 교육대학원 학술연구회 1967 論文集 - 서울대학교 교육대학원 Vol.4 No.-

本 硏究는 이제까지 體系的인 地球科學 敎科書가 없었던 關係로 本人 自身이 ESCP를 읽고 地球科學 內容을 理解함과 同時에 이를 實際授業을 通해 檢討하여 우리의 實情에 알맞게 適應시키려는 데 그 目的이 있다. 特히 우리나라에 맞는 敎育資料를 蒐集하고 國産材料로 實驗器具를 製作하여 使用해 봄으로써 適合한 形態의 內容과 方法을 發展시켜 보려는 데 重點을 두었다. 또한 앞으로 改正될 地球科學敎育課程과 敎材의 製作 및 敎師 再敎育을 爲한 基礎資料를 蒐集 作成하려는 것이 本 硏究의 또 하나의 目的이다. The earth science courses have been included in high school curriculum seen in many countries. The Ministry of Eduation of the Korean Government has decided to adapt it as a compulsory course in high school science from the academic year of 1968. Now it is very urgent to prepare better curriculum, good text books, teacher's guides and well designed laboratory equipment of reaonable price with well-written laboratory mannuals and so on for the new earth science education. I have investigated the best texts and related materials of the earth science education in that of E.S.C.P in the United State to prepare reference materials for the revision of the earth science curriculum in Korean high school and to test the possibility of contribution of ESCP materials to Korean high school. I have also studied the leading philosophy, the course contents, the method of approach and the laboratory experients of the ESCP earth science curriculum. I have established ESCP pilot course at the attached high school of College education, Seoul National University., to explore the possibility of contribution of ESCP materials to Korean high school. As a result I have discovered: 1) The ESCP materials are very good reference to improve our country's earth science education. 2) If we revise only the 12% of ESCP text contents, it will be good to improve our country's earth science education. 3) If we replace the 11% of the photos and figures, it will adapt to our country. 4) If we prepare 20% of Laboratory kits with reasonable price, it will contribute to our country's earth science education.
