돌산도 쇄파대에 사는 쿠마류 Bodotria biplicata 의 조하대 대상분포
서해립(Hae Lip Suh),구영경(Young Kyung Koo) 한국수산과학회 1997 한국수산과학회지 Vol.30 No.1
Subtidal zonation of a cumacean Bodotria biplicata was investigated in the sandy shore surf zone of Dolsando, southern Korea. Three replicate samples were taken with a sledge net at three sites, such as the surface and bottom of 1 m depth and water`s edge, at hourly intervals over the neap and spring tide cycles on January 1993 (n=225). B. biplicata, the most dominant cumacean in this area, exhibited peak density at the bottom while about 0.6% of total catch was collected at the surface. Mean density during the neap tide cycle was slightly higher than that during the spring tide cycle. The depth of subtidal zone influenced the total catch of 8. biplicata. The changes in density were related to the depth of subtidal zone rather than day-night cycle or ebb-flood tide. The results obtained in this study suggest that the diel vertical migration is not distinct. During both neap and spring tide cycles, B. biplicata attained a density maximum at the same level of about 90 ㎝ below lower low water (LLW). It is likely, therefore, that this species performs shore- and seaward horizontal migration fortnightly. The speed and distance of migration may be directly related to the beach slope and tide range. Ontogenetic differences in subtidal distribution were observed. Juveniles and manca larvae tended to occur lower areas than the adults. Such differences may reduce intraspecific competition for diets.

본 연구는 치위생교육을 통해 형성된 치위생(학)과 학생의 전공만족도와 전문직관 정도를 파악하고 상관관계를 분석하여 치위생전문직관 형성교육에 필요한 자료를 제공하기 위해 조사하여 분석한 결과 다음과 같은 결론을 얻었다. 1. 치위생(학)과 학생의 전공만족도는 인식만족이 가장 높았으며, 교과만족이 가장 낮은 것으로 나타났다. 2. 전공만족도는 3.51점으로 나타났으며, 성적이 높은 학생일수록, 종합병원 및 대학병원에 취업을 원하는 학생일수록 전공만족도가 높은 것으로 나타났다(p<0.01, p<0.05). 3. 치위생(학)과 학생의 전문직관은 치위생의 독자성이 가장 높았으며, 사회적 인식이 가장 낮은 것으로 나타났다. 4. 전문직관은 3.48점으로 나타났으며, 성적이 높은 학생일수록 전문직관이 높은 것으로 나타났다(p<0.05). 5. 전공만족도와 전문직관의 관계는 전공만족도가 높을수록 전문직관이 높은 것으로 나타났다(p<0.001). 결론적으로 치위생(학)과 학생들의 긍정적인 전문직관의 확립을 위해 전공만족도를 높일 수 있도록 학생들의 학업성취도 향상과 졸업 후 취업에 대한 비젼을 제시할 수 있는 다양한 노력이 필요하다고 사료된다. The purpose of this study was to examine the satisfaction of dental hygiene students receiving dental hygiene education with their major, their view of profession and the correlation between their satisfaction with major and view of profession in an attempt to provide some information on how to teach students to accept the occupation of dental hygienist as a profession. 1. As for satisfaction with major, the dental hygiene students were most satisfied with awareness of dental hygienist, and they were least satisfied with courses. 2. The major satisfaction score was 3.51. The students whose academic standing was higher and who wanted to work in a general hospital or university hospital expressed more satisfaction with their major(p<0.01, p<0.05). 3. Concerning view of profession, they placed the most significance on the independence of dental hygiene, and put the least value on social awareness. 4. The view of profession score was 3.48. The students whose academic standing was higher regarded the job of dental hygienist as a profession(p<0.05). 5. As to the relationship between satisfaction with major and view of profession, those who were more satisfied with their major gave more weight to the job of dental hygienist as a profession(p<0.001).
