남해 연안 개조개 (Saxidomus purpuratus) 치패 서식지의 퇴적환경
홍서현,김영혜,유준택,김다혜 한국패류학회 2017 The Korean Journal of Malacology Vol.33 No.4
This paper was aimed to sedimentary environment appropriate for survival and inhabit of Saxidomus purpuratus juvenile. The sediment type in Goheung coast was dominated by silt (78.1 ± 0.6%), and followed by clay (20.2 ± 0.7%) and sand (1.7 ± 0.8%), and that in Hwagye coast was similar to that of Goheung coast (Silt 78.5 ± 0.7%, Clay 20.7 ± 0.6% and Sand 0.8 ± 0.4%). Thus the Saxidomus purpuratus juvenile habitat was mainly composed of silt. In case of Saxidomus purpuratus adult habitat, silt (79.6 ± 0.5%), and followed by clay (19.7 ± 0.5%) and sand (0.7 ± 0.3%). But, the research results, sedimentation environment showed the highest response rate (50%) as the environmental factors for juvenile survival. Sandy silty showed the highest response rate (83%) for the most appropriate sedimentation environment.
전라남도에서 주꾸미 (Amphioctopus fangsiao) 유어낚시를 통한 지역별 어획 특성
홍서현,윤병선,김다혜,김성태,문성용 한국패류학회 2019 The Korean Journal of Malacology Vol.35 No.3
We examined the regional catch characteristics of leisure fishing on Amphioctopus fangsiao in Jellanam-do Province from January 2017 to October 2018. The daily catch data of A. fangsiao was examined by korea fisheries cooperative in 8 regions and by leisure fishing in 11 regions of Jeollanam-do province. The population of A. fangsiao by leisure fishing in Jeollanam-do province was estimated to 49,397. In Yeosu, there were estimated to 40,490 population and it accounted for 81.9% of total population of leisure fishing on A. fangsiao. The total catch of A. fangsiao was the highest in Goheung, and the catch per unit effort (CPUE, kg/vessels) was highest in Mokpo in 2017 and Jangheung in 2018. The CPUE of A. fangsiao by leisure fishing was the highest in Yeosu and the lowest in Muan. The CPUE of catch data of korea fisheries cooperative and leisure fishing of A. fangsiao, which accounted for the catch ratio of leisure fishing ranging from 0.4 to 406 times higher than catch data of korea fisheries cooperative. Therefore, the exact catch data of A. fangsiao needed for efficient resource management and protection and also need to catch data of korea fisheries cooperative and by leisure fishing. It is necessary to exact methods to find an uncounted catch data by leisure fishing on A. fangsiao.
남해 연안 개조개 (Saxidomus purpuratus) 의 서식지 퇴적 환경에 따른 개체군 서식밀도
홍서현,김영혜,유준택 한국패류학회 2017 The Korean Journal of Malacology Vol.33 No.3
This paper was aimed to determine the population density of Saxidomus purpuratus according to the habitat environmental conditions of the southern coastal waters in Korea. The sediment type in Yeosu coast was dominated by silt (79.6 ± 0.5%), and followed by clay (19.7 ± 0.5%) and sand (0.7 ± 0.3%), and that in Geoje coast was similar to that of Yeosu coast (Silt 77.6 ± 0.4%, Clay 21.7 ± 0.7% and Sand 0.67 ± 0.4%). Thus the Saxidomus purpuratus habitat was mainly composed of silt. The population density of S. purpuratus in Yeosu coast was in the range of 0.5-2.0 ind./m2 and that in Geoje coast was 0.25-7.25 ind./m2. Among the caught individuals, the`proportion of immature individuals was 7.6% and 13.4% in Yeosu and Geoje coast, respectively.

This study aims to compare and analyze ‘Understanding of Culture and Arts Education Field and Practice’which is one of subjects of curriculum for 2nd grade arts & culture education instructor license designated by the Ministry of Culture, Sports and Tourism as a national license of Korea in accordance with the 「Act on Support for Arts and Culture Education」 and field practice for 2nd grade regular teachers which is the most representative qualification system in Korea for training of teachers. This study is also aiming at suggesting direction for development by heightening the value and efficiency of field practice for 2nd grade arts & culture education instructor license by raising problems with operation system of current field practice and suggesting improvement plans for the problems. For the foregoing, the researcher of this study investigated operation system and syllabus of the subject‘Understanding of Culture and Arts Education Field and Practice’which is the curriculum for 2nd grade arts & culture education instructors, and pointed out problems in both quantitative and qualitative levels after investigating, comparing and analyzing operation system of field practice for 2nd grade regular teachers. As a result of comparative analysis at quantitative level, this study found that field practice for 2nd grade arts & culture education instructors is just an experience and the times are insufficient as compared to 2nd grade regular teachers. As an improvement plan for the aforementioned, this study suggested to operate‘Understanding of Culture and Arts Education Field’and‘Culture and Arts Education Field Practice’subjects by dividing into two categories for expanding times of field practice. Results of comparison and analysis at the qualitative level show that field practice for 2nd grade arts & culture education instructors has ambiguity of operation system, lacks in field practice operation manual, operating and practice agencies. As improvement plans for such problems, this study suggested to systemization of field practice operation system, setting up field practice management system and establishment of field practice support center by regional groups. In addition to the above, continued interest and a lot of researches other than this study for heightening the value and efficiency of arts & culture education instructor license are considered necessary, and various possibilities of development shall also be suggested for arts & culture education instructor system as society, culture and times change.
