沈載炯 한국교육학회 1966 敎育學硏究 Vol.4 No.1

人間 生活에서 敎育의 要求가 生活의 必要에서 온 것이라면, 敎育의 目的은 人間의 實際生活을 돕는 데 있어야 할 것이고 따라서 敎育의 成果도 우리 生活이 改善된 實績에서 찾아 보아야 할 것이다. 그럼에도 不狗하고 오늘날 學校가 敎育의 本質이나 學校의 任務를 忘去하고, 生活과는 동떨어진, 지난 文化 遺産의 傳達處로 學理探究의 象牙塔라는 높은 담을 쌓게 되는 世紀的인 危機를 意識하게 되자 이를 克服하기 위한 試圖가 數年前부터 生活中心 교육으로, 勞作中心 교육으로 鄕土開發교육으로, 推進 展開되어 왔음은 敎育本然의 姿勢로 또는 學校 本然의 任務로 돌아오는 믿음직한 現象이요, 必然的인 歸結이라 아니 할 수 없다.

심재형,이원호,Shim, Jae Hyung,Lee, Won, Ho 한국해양학회 1983 韓國海洋學會誌 Vol.18 No.2

Qualitative and quantitative phytoplankton samples collected during a cruise in the southeastern sea of Korea in September 1981, were analysed. A total of 185 species of phytoplankters were identified in the present study. Of the numbers 14 species of diatoms and 56 dinoflagellate forms were found. The rest were 3 silicoslagellate forms, a cryptomonad and a euglenoid each. On the bases of the analyses of the phytoplankton communities, two vegetation areas were recognized. It is demonstrated that the extent of each vegetation area largely depends on hydrographical features. In southeastern coastal waters, the vegetation was fairly rich, and consisted of small celled diatoms and minute flagellates. In the northern part of the area, abundant phytoplanktons were present consisting of various diatoms and dimofalgellates. The size of standing stock of phytoplankton was compared with hydrography and the specific composition of phytoplankton. The importance of mixing between the Tsushima warm current water and North Korean cold water in distributing phytoplankton stocks was stressed.

To characterize community structure and distribution of phytoplankton, cluster analyses are performed on quantitative data of phytoplankton collected from the southwestern sea of Korea in early summer, 1980. The cluster analysis shows that the phytoplankton of the study area consists of three distinct characteristic communities, representing different water masses. The species of the first community, predominant in the southwestern coastal were of the main land, are mostly neritic and cold water diatoms. The second community consists of neritic and oceanic diatoms, a few flagellates and an euglenoid. These species are predominant in the vicinity of Jeju Island with warm and high saline waters which seems to be a branch of the Kuroshio Current. The species of the last community, consisting primarily of small-sized dinoflagellates, are predominant in the rest part of the study area with warm and low saline water. Addition, the vertical distributions of phytoplankton and environmental factors show that high concentration of phytoplankton cells, chlorophyll-a and dissolved oxygen are observed near the seasonal pycnocline in the off-coastal area. Fraction of nanoplankton take the above 90% of the total cell concentration in the surface mixed layer of off-coastal area where the seasonal pycnocline develops in summer.

본 연구에서는, Ohotomo 등이 모음의 학습과 인식을 위해 구성한 BP 구조 신경망의 학습을 위해 사용하였던 입력 패턴의 방법을 보완하여, 포만트 주파수의 대역폭을 고려한 측면값을 학습용 입력패턴에 두어 수렵 속도와 인식율을 높이고자 한다. 본 연구에서 제안한 방법이 오인식율에서는 $30{\%}$정도의 감소와 수렴 속도며에서는 $7{\%}$의 증가를 컴퓨터 시뮬레이션을 통하여 알 수 있었다. In this work Ohotomo et al., neural network model for learning and recognizing vowels is modified in order to reduce the time for learning and the possibility of incorrect recognition. In this modification, the finite bandwidth of formant frequencies of vowels are taken into consider-ations in coding input patterns. Computer simulations show that the modification reduces not only the possibility of incorrect recognition by about $30{\%}$ but also the time for learning by about $7{\%}$.

韓國 群山近海域에서의 植物플랑크톤 群集

심재형,유신재 한국해양학회 1985 韓國海洋學會誌 Vol.20 No.1

Multivariate analyses has been performed on both qualitative and quantitative data of phytoplankton samples collected off the coast of Kunsan in October, 1980, and in March, 1981. The result shows that structure of the phytoplankton cmmunity largely depended on hydrological conditions. Thus the study area can be divided into three phyto-hydrographic zones; the waters under influence of the proper water of the Yellow Sea, the waters where mixing with fresh water occurred, the waters from the south. Biomass was estimated of plasma volume and cell carbon content. The mean value of cell carbon was 30.0$\mu\textrm{g}$/$\ell$ in October and 26.6$\mu\textrm{g}$/$\ell$ in March. Relatively low value of biomass seems to be related to great turbidity of the area. Microflagellates of about 5$\mu\textrm{m}$ were abundant with a density of million cells per liter. Their abundance showed on considerable seasonal variation.

This study deals with the marine dinoflagellates observed in 50 samples collected in the vincinity of Yeosu from August 1979 to May 1980. Forty-nine species were identified and these taxa are attributed to 10 genera, of which 2 are infraspecific taxa. Two families, 3 genera, and 32 species are new records for the Korean coastal waters. Small dinoflagellates recorded in this study are ascribed to the use of volumetric samplers instead of nets. In this area, the armored forms are the most important components of the dinoflagellates (39 taxa). All species are illustrated by photomicroscopy. There are 49 pictures of taxa. An attempt has been made to provide more correct references to each species. There are comparative descriptive information, taxonomic comments, and distributional data for each species.

In order to the species composition and abundance distribution of zooplankton, quantitative samples collected in the Yellow Sea in April 1981 were analyzed. Ranges of temperatures and salinities of the study area were 4.55-9.80$^{\circ}C$ and 32.02-32.88 , respectively. Total 33 taxa were identified from all samples collected. Species composition along the stations showed no remarkable variations. Copepods were the most imporatnt components of zooplankton community in the study area. Dominant species of copepods were Oithona similis, Acartia clause and Centropages mcmurrichi. Appendicularia, Chaetognatha, Amphipod, and Euphausiid were distributed with minor abundance. Average biomass(wet weight) of zooplankton was 107mg/㎥, and the biomasses of zooplankton at offshore stations were greater than those of inshore stations in the study area. Average individual number of zooplankton was 1,915 indiv./㎥, and the variations along stations showed the same trend as in biomass. From the result of clustering with correlation coefficients calculated with the indivecual numbers per cubic meter for 20 zooplankton constituents at each station it was suggested that temperature had far reaching sffect on the distribution of zooplankton in the study area.

해수에 잠긴 인공기질 표면에서 미세조류의 부착과 성장: II. 엽록소와 일차생산력

심재형,강정훈,조병철,김웅서,배세진,Shim, Jae-Hyung,Kang, Jung-Hoon,Cho, Byung-Cheol,Kim, Woong-Seo,Pae, Se-Jin 한국해양학회 1999 바다 Vol.4 No.2

해수에 잠긴 인공기질 표변에서 노출시간에 따른 부착미세조류의 성장과정을 이해하고자 유리슬라이드에 부착한 미세조류의 수도 변화와 엽록소 농도 변화를, 그리고 커버글래스에 부착한 미세조류의 엽록소 농도 변화와 일차생산력 변화를 인천항내에서 1996년 5월과 6월 그리고 1997년 1~2 월에 걸쳐 조사하였다. 유리슬라이드 상의 부착미세조류 군집의 엽록소 농도와 부착규조류의 수도는 연구기간동안 각각 최대 62.5 mg chl a $m^{-2}$와 $144{\times}10^3$ cells $cm^{-2}$를 나타냈다. 엽록소 농도는 노출시간에 따라 증가하였으며, 부착규조류의 수도변화와 유의성 있는 상관관계를 나타냈다. ($r^2=0.79$, p<0.001). 커버글래스 상의 엽록소 농도는 5월, 6월에 노출기간동안 각각 최대 31.1 mg chl $a\;m^{-2}$과 65.4 mg chl $a\;m^{-2}$를 나타낸 뒤 감소하였다. 그러나 1~2 월에는 98.9 mg chl a $m^{-2}$까지 계속 증가하였다. 일차생산력은 5월과 6월 그리고 1~2 월에 각각 최대 63.1 mgC $m^{-2}\;h^{-1}$, 347.0 mgC $m^{-2}\;h^{-1}$ 그리고 78.3 mgC $m^{-2}\;h^{-1}$의 값을 보였다. 5월과 6월의 일차생산력은 엽록소 농도 변화와 같은 양상으로 노출시간에 따라 증가하다가 감소하였다. 그러나 1~2 월의 일차생산력은 노출 26 일 이후 감소하였고, 엽록소 농도는 계속 증가하였다. 증가하던 일차생산력이 현저히 감소한 두 가지 경우는 엽록소 농도와 광량당 $P^B$의 감소가 같이 나타난 경우(5월, 6월)와 광저해로 인한 광량당 $P^B$의 감소에 기인한 것으로 보이는 경우(1~2월)였다. 본 연구결과는 해수에 잠긴 인공기질표변에 부착한 미세조류의 엽록소 농도와 일차생산력 측정을 통해 생물막 형성과정 중에 나타나는 부착미세조류의 생물량과 생리적 상태의 변동을 신속하게 분석할 수 있음을 시사하였다. To understand the growth of attached microalgae to the immersed artificial surfaces in seawater with exposure time, chlorophyll a (chl a) concentration and abundance of attached microalgae to glass slides, and primary productivity and chl a concentration on coverglasses were investigated in Incheon Harbour in May, June 1996 and January-February 1997. Chl a concentrations of microalgae and abundances of diatoms attached to glass slides reached 62.5 mg chl a $m^{-2}$ and $144{\times}10^3$ cells $cm^{-2}$, respectively, during the study period. Chl a concentrations increased with exposure time, and they were significantly correlated with the abundances of attached diatoms ($r^2=0.79$, p<0.001). The chl a concentrations of attached micro algae on coverglass reached the maximum values of 31.1 mg chl a $m^{-2}$ and 65.4 mg chl a $m^{-2}$, and then decreased in May, June 1996. But in January-February 1997, the chl a concentration increased continuously up to 98.9 mg chl a $m^{-2}$. The primary productivity reached the maximum values of 63.1 mgC $m^{-2}\;h^{-1}$, 347.0 mgC $m^{-2}\;h^{-1}$ and 78.3 mgC $m^{-2}\;h^{-1}$, respectively, in May, June and January-February. The primary productivity in May and June varied in accordance with chl a concentrations. But in January-February, the primary productivity decreased from 26 days of exposure while chl a concentration continued to increase. Two cases that primary productivity decreased abruptly seemed to be caused by decrement of chl a and light specific $P^B$ (chl a specific primary productivity) (May and June) and by decrement of light specific $P^B$ due to photoinhibition (January-February). The results of present study indicated that chl a concentrations and the primary productivity of microalgae attached to artifical surfaces immersed in seawater would expedite analysis of dynamics of biomass and physiological status of attached microalgae during biofilm formations.

심재형,배세진 한국해양학회 1985 韓國海洋學會誌 Vol.20 No.2

영일만의 식물플랑크돈의 분포와 수괴의 수리적 특성과의 상호관계에 관한 연 구가 1983년 12월부터 1984년 7월에 걸쳐 이루어졌다. 식물플랑크톤 현존량의 시간 적 변화는 수괴의 수직적 안정도와 영양염의 공급을 수반한 담수의 유입과 밀접한 관계를 보였다. 우점종의 시간적 동태는 일반적인 천이양상과 일치하였고, 특히 Skeletonema costatum은 매 조사시기마다 우점종으로 나타났다. 식물플랑크톤의 색소량과 개체수는 세포의 크기변화에 따른 차이는 있어도 전반적으로 좋은 상관관 계를 보였다. 다변량분석에 따른 조사해역의 구분은 수괴의 수리적 특성과 식물플 랑크톤의 분포양상과의 상호연관성을 잘 반영하고 있다. The interrelationships between distribution of phytoplankton and hydrographical conditions were studied from December 1983 to July 1984 in Yeongil Bay. The temporal variation of phytoplankton abundance seems to be mainly influenced by the vertical stability of water column and the freshwater run-off accompanied with possible nutrient input. The temporal progression of dominant species shows general succession pattern, especially skeletonema costatum was found a dominant species in each month. Although the differences between concentration of chlorophyll a and abundance of phytoplankton may be caused by cell size variation, during the study period they show felatively good linear manner. The phytohydrographic region based on multivariate analysis reflects the relationships between hydrographical condition and distribution pattern of phytoplankton.
