Portugal 굴(Crassostrea angulata) 및 Olympia 굴(Ostrea lurida) 의 이식 성장에 관한 연구
배경만,배평암 한국수산학회 1972 한국수산과학회지 Vol.5 No.1
본 시험은 일본 Miyagi Ken(宮城縣) 굴 연구소에서 1969년 채묘된 O. lurida 및 C. angulata를 항공편으로 우송하여 1977년 1훨 20일부터 12월까지 경남 거제군 하청면 연구리 옥계지선에서 수하식으로 성육시켜 조사한 것이며 그 결과는 다음과 같다. 1. O. lurida는 평균 각고 36.4㎜ 각장 29.5㎜인 둥근모양으로서 소형굴로 자랐고, C. angulata는 각고 87.4㎜, 각장 52.3㎜인 타원형으로서 대형굴 형태로 성장했다. 2. O.lurida, C.angulata는 다같이 수온이 16℃ 이상일 때 6,7월시에 성장도가 좋았으며, 이때의 비중은 1.01717∼1.02368 사이였다. 3. 각고 각장간의 상대적인 변화는 O. lurida는 년간 큰 차가 없었으나, C. angulata는 7월에서 부터 현저한 차를 이루어 11월에 35.8㎜로 그 차가 가장 컸다. 4. 폐사율은 O.lurida는 35.2%였으며, C. angulata는 21.7%를 나타냈다. This results concerning the growth of transplanting of the oyster seed, Crassostrea angulata and Ostrea lurida, which were transplanted from Japan by air, and cultivated by the raft suspended method at the coast of Yeongoo-Ri, Koje-Goon, located on the southern coast of Korea from January to December 1970, are as follows. 1. The mean shell height of O. lurida was 36. 4㎜, and the shape of the shell was round and small, On the other hand, the mean shell height of C. angulata was 87.4㎜ and the shell length was 52.3㎜, and the shape of the shell was oval and large. 2. O. lurida and C. angulata oysters grew well when the water temperature was above 16℃ and the specific gravity ranged from 1.0171 to 1.0236 from June to July. 3. There was a little difference in relative variance between shell length and height of O.lurida but significant difference was shown in C. angulata from July to November. 4. The mortality rate of O, luria was 35.2% and that of C. angulata was 21.7% respectively,

The purpose of this study is to suggest healthcare facilities as ecological architecture. The physical environmental health of human mainly depends on the quality of architectural natural environment. so it is very important to prepare rehabilitation landscape environment on the healthcare setting. this study proceeds to search planning factors of healthcare facilities in ecological architecture through study of Ecological Theory of Perception. It also explain the important of ecological planning methods, and suggest a way of architectural planning oh healthcare facilities in future, through the study of the feature and analysis of application methods. The future rehabilitation hospital should provide reduction of the effect on environments, increasing amenity, rehabilitation landscape. To create healthcare facilities ecological is essential not only to human but also human survival.
Named entity recognition using transfer learning and small human- and metapseudo- labeled datasets
배경만,임준호 한국전자통신연구원 2024 ETRI Journal Vol.46 No.1
We introduce a high-performance named entity recognition (NER) model for written and spoken language. To overcome challenges related to labeled data scarcity and domain shifts, we use transfer learning to leverage our previously developed KorBERT as the base model. We also adopt a meta-pseudo-label method using a teacher/student framework with labeled and unlabeled data. Our model presents two modifications. First, the student model is updated with an average loss from both human- and pseudo-labeled data. Second, the influence of noisy pseudo-labeled data is mitigated by considering feedback scores and updating the teacher model only when below a threshold (0.0005). We achieve the target NER performance in the spoken language domain and improve that in the written language domain by proposing a straightforward rollback method that reverts to the best model based on scarce human-labeled data. Further improvement is achieved by adjusting the label vector weights in the named entity dictionary.
