敎職成長을 爲한 敎育大學出身의 勤務配置 條件에 對한 調査硏究

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,박용철,Shim, Jae Hyung,Park Yong Chul 한국해양학회 1984 韓國海洋學會誌 Vol.19 No.1

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.

심재형,신은령,최중기,Shim, Jae Hyung,Shin, Eun-Young,Choi, Joong Ki 한국해양학회 1981 韓國海洋學會誌 Vol.16 No.2

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.

심재형,윤구현,SHIM, JAE HYUNG,YUN, KU HYUN The Korean Society of Oceanography 1990 韓國海洋學會誌 Vol.25 No.4

The zooplankton of Chonsu Bay was collected and analyzed to study the seasonal variation in species composition and abundance, and to estimated the total annual production of Copepoda. With a pronounce seasonal fluctuations in species composition and abundance, Paracalanus indicus and Corycaeus affinis predominated during summer and fall, while larger species such as Centropages abdominalis and Acartia dominated in spring. Zooplankton abundance showed the minimum in March, then increased and reached the maximum in August. It is suggested that seasonal variation of zooplankton as well as temperature. Being productive compared with other areas, the estimated total production of Copepoda was 134 g/100m$^3$/yr (dry weight).

인조기판 위에서 해양 부착생물의 발달 및 천이

심재형,정문섭 한국해양학회 1987 韓國海洋學會誌 Vol.22 No.4

Fouling communities developing in Jinhae Harbor and Masan Bay were studied by slide and panel immersion test during the period from Dec., 1982 to Nov., 1983. The total viable count of bacteria was estimated more than 1.7${\times}$ 10$\^$4/CFU/$\textrm{cm}^2$ after 15 days of immersion and 46 taxa of benthic diatoms were classified in micro-community. Progressional change of fouling communities was clearly shown and dominant diatom species are Licmophora flavellata, Navicula grevillei, and Nitzschia closterium Major macrofouling organisms are Mytilus edulis, Balanus amphitrite amphitrite, Hydroides ezoensis, and Celleporina sp. Wet weight production of macrofouling organisms exceeds 500g/100cm$\^$2/ after 5months of immersion. Regional defferences in community development are clearly shown in two study areas, and mainly due to the disparities of physicochemical stability and nutritional status of ambient water. Seasonality of larvae and the growth rate are the important factors in fouling community development. Overall process of community development is as follow : bacteria and diatoms-multicellular algae-barnacle, mussels and polychaete-sponge, anemone and ascidian.

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 $7{\%}$.

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.
