학교도서관에 대한 초·중등 학생의 장소성 형성구조에 관한 연구

이병기,Lee, Byeong-Kee 한국도서관정보학회 2017 한국도서관정보학회지 Vol.48 No.2

학교도서관은 공간임과 동시에 장소이다. 가정과 집의 개념이 다르듯이 공간은 물리적 형태를 말하고, 장소는 각 개개인의 경험에 의한 주관적 개념이다. 초 중 고 학생은 사회적, 인지적 발달단계가 다르기 때문에 학교도서관에 대한 느낌 즉, 장소성이 다를 수 있다. 이에 본 연구는 초 중 고 학생 간에 장소성 형성요인에 대한 차이를 규명하고, 이 장소성이 장소애착과 장소가치인식을 매개로 하여 학교도서관을 이용하고자 하는 행동의도로 이어지는지 그 과정을 검증하였다. 590명의 초 중 고 학생들로부터 수집한 설문 데이터는 SPSS 19와 AMOS 19를 사용하여 분석하였다. 연구 결과, 물리적 요소, 활동 행태적 요소, 심리적 요소 모두 초 중 고 학생의 학교도서관에 대한 장소성 형성에 영향을 미치고 있음을 확인하였다. 초등학생은 중학생과 고등학생에 비해 물리적 요소, 활동 행태적 요소에 의한 영향을 크게 받고 있으며, 이는 통계적으로 유의미한 차이를 보였다. 또한 장소성은 장소애착, 장소가치인식을 매개로 하여 학교도서관을 이용하려는 행동의도로 연결되고 있음을 확인하였다. School Library is both a space and a place. The difference between space and place is the same as in the difference between house and home. Space may be described in terms of physical shape. Place is concept that formulated by personal experience. The social and cognitive developmental stages of elementary, middle and high school students are different, so the placeness or sense of place may be different. The purpose of this study is to figure out the differences in elementary and secondary school student's formative factors of placeness and examine the process that those factors are connected to the results of the user behavioral intentions through the medium of place attachment, place value perception. The data are collected from 590 students and analyzed by SPSS 19 and AMOS 19. The results of this study are as follows. The physical, active behavioral and psychological factors affect on placeness formation of elementary and secondary school students in school libraries. Elementary school students are significantly affected more by physical factors, active behavioral factors than middle and high school students. This study confirmed the process that those factors are connected to the results of the user behavior through the medium of place attachment, place value perception.

백워드 설계 모형을 적용한 "도서관과 정보생활" 교과의 교수설계에 관한 연구

이병기,Lee, Byeong-Ki 한국비블리아학회 2011 한국비블리아학회지 Vol.22 No.3

각 교과의 교사들이 효과적으로 수업을 전개하기 위해서는 사전에 수업 전개 과정을 설계할 필요가 있다. 전통적으로 교수설계에 널리 적용되고 있는 모형으로는 딕과 케리, ADDIE, ASSURE 등이 있다. 그러나 전통적인 교수설계 모형은 교과 내용이 소규모 단원으로 분절되어 있어서 학생들이 교과의 본질적인 이해에 이르기 어렵다는 한계가 있다. 이러한 문제를 해결하기 위해서 위깅스와 멕타이는 백워드 설계 모형을 제안하였다. 백워드 설계 모형은 가르쳐야 할 내용과 활동을 결정하기 전에 먼저 평가를 고려하는 교수설계 방법이다. 이에 본 연구에서는 백워드 모형의 구조를 분석하고, 정보활용교육을 위한 '도서관과 정보생활' 교과에 백워드 설계 모형을 적용함으로써 정보활용교육의 효과적인 교수-학습 방법을 모색하고자한다. 본 연구에서는 '도서관 과 정보생활' 교과의 백워드 교수설계를 위해서 위깅스와 메타이가 고안한 템플릿을 적용하였다. Teachers must design instruction to meet effective teaching and learning before teaching implementation. The traditional models of instructional design such as Dick and Carey, ADDIE and ASSURE have been widely applied. However, the traditional models of instructional design have limitation in that students fail in deep understanding of subject content because of break down essential goal of the unit small pieces of contents. To solve this problem, Wiggins and McTighe have suggested backward design. Backward design is a method of designing instruction by setting evaluation before choosing activities or content to teach. Therefore, this study explores the effective teaching and learning by analyzing structure of backward design and appling backward design to 'Library and Information Life' subject for information literacy education. Backward design for 'Library and Information Life' subject applies the template which Wiggins and McTighe devised for instructional design.

기선기현강의 연구 1, 재래식 어구의 유구저황과 그물꼴에 관하여

이병기,양룡림,서영태,손부일,LEE Byoung-gee,YANG Yong-rim,SU Young-tae,SON Boo-il 한국수산과학회 1971 한국수산과학회지 Vol.4 No.3,4

자루 입구의 둘레가 력자망지 150골(75m)되는 권현망어구의 $\frac{1}{10}$ 크기의 모형을 제작하여, 어구의 유분저항과 린망중의 그물꼴에 관하여 실험한 결과 다음과 같은 결론을 얻었다. 1. 모형 어구로부터 환산된 실물어구의 유분저항은 (R은 kg, v는 m/sec) 전저항 $$R_1=30,000\;v^{1.2}\;(0.2{\leqq}v{\leqq}1.0)$$ 자루 저항 $$R_2=16,000\;v^2\;(0.2{\leqq}v{\leqq}0.6)$$ 2. 예망중의 그물꼴은 (1) 오비기(extension wing) 발줄의 전 길이 중, 앞 끝부터 약 $70\%$ 까지는 직선상으로 깊어지며, 해저에 나란한 부분은 안쪽 약 $30\%$ 정도이다. (2) 수비(inside-wing)의 마깥 언저리는 예망속도가 0.2 m/sec이상 되면, 자루와 수비의 연결부 보다 더 뒤로 쏠려서, 어군을 자루로 유도하는 데 합리적인 형상이 아니다. 이것을 시정하기 위해서는, 수비의 깊이 방향의 코스를 $\frac{1}{2}\~\frac{2}{3}$ 정도로 줄이거나, 또는 그물코의 크기를 그런 정로로 줄임과 동시에, 자루 입구에서 오비기 발줄로 가는 힘줄을 넣어서 수비에는 예망장력이 적게 미치도록 하는 것이 좋다고 생각된다. (3) 앞치마(lower bosom)는 예망속도가 0.2m/sec이상 되면, 뒤끝치 들어 올려져서 수심이 깊은 어장에서는 수비에까지 유도된 어군도 이리로 해서 도피할 우려가 있다. (4) 문턱(upper bosom)의 계관 상의 경사 각도는 $35\~40^{\circ}$이다. 이것은 어군을 자루그물로 유도하게 유도하기에는 너무 크다고 보아진다. 따라서, 문턱은 좀 더길게 해서 경사 각도를 작게 하는 것이 좋다고 생각된다. (5) 자루(bag net)의 모양은 예망속도가 0.2m/sec 이상 되면, 뒤쪽이 앞쪽보다 좁아져서, 구성상 앞쪽보다 뒤쪽을 넓게한 의도가 나타나지 않는다. 따라서 자루 그물은 전체 모양이 길다란 원통형이 되게 구성하는 것이 합리적이라고 생각된다. A boat seine has been used as a major fishing gear for catching anchovy (Engraulis japonica) in the southern coastal waters of Korea since 1920s. The original seine was operated by two rowing boats as the haul seine. The rowing boats were, in recent, replaced by powered boats. The net size was enlarged by more than three times the original nit as they began to by operated in the deeper waters of approximately sixty meters. However, there are many problems in the efficiency of the fishing gear to be improved. The authors studied on the hydrodynamic resistance and performance of the boat seine net of the 1/10 scale model in tow. The results are summaried as follows. 1. The hydrodynamic resistance converted from model experiment into the full scale is: $$R_1=30,000\;v^{1.2}\;(0.2{\leqq}v{\leqq}1.0)$$ $$R_2=16,000\;v^2\;(0.2{\leqq}v{\leqq}0.6)$$ where $R_1$ and $R_2$ denote the resistance of whole gear and of bag net in kg respectively, and v the speed of flow in m/sec. 2. In the extension wing, approximately seventy percent of the length of the ground rope from the towing end to the inside-wing slopes down from sea level toward the sea bottom, while the thirty percent of the inside of it remains parallel with th: 5:a level. The performance is regarded to b: inefficient for driving fish shoal into the inside-wing, especially for the shoal diving suddenly. 3. At the towing speed higher than 0.2 m/sec, the trailing edge of the inside-wing is blown backward beyond the seaming line connecting the inside-wing and the mouth of the bag net. It is regarded as an unreasonable performance to drive the fish shoal smoothly into the bag net. 4. At the towing speed higher than 0.2 m/sec, the posterior end of the lower bosom is lifted up above the level of the ground rope of the inside-wing. It is considered that the fish shoal diving suddenly can escape through the discrepancy between the lower bosom and the sea bottom, even if the ground rope of the inside-wing sweeps the sea bottom. 5. The angle of inclination of the upper bosom is estimated as $35\~40^{\circ}$. It seems that the inclination is too steep to drive smoothly the fish shoal diving toward the sea bottom into the bag net. 6. In structure, circumference of the posterior section of the bag net is wider by 1.3 times that of the anterior section. Actually in towing at a speed higher than 0.2m/sec, however, the circumference of the posterior section becomes smaller than that of the anterior section. It is recommended to be designed in a long cylindrical form.

활멸치의 집약적 생산수단에 관한 연구 -II 권현망을 일부 개조한 어구에 의한 어호 및 그 어호물의 축양시험

이병기,서영태,이주희,Lee, Byoung-Gee,Young, Tae-Su,Lee, Ju-Hee 한국수산해양기술학회 1979 수산해양기술연구 Vol.15 No.1

재래식 권현망의 천장망을 제거하고 옆판 위 언저리에 뜸을 장치한 어구에 의하여 활멸치의 어획을 시험하고, 동시에 이렇게 어획한 멸치를 버팀대를 써서 축양조를 예인하는 방법으로 축양 시험을 실시한 결과 대략 다음과 같은 결론을 얻었다. 축양개시 15일후의 생잔률은 최고 약 71%여서 다른 어구. 어법에 의한 생잔률 보다는 낮지마는, 권현먕 어구 자체가 한국의 멸치 어업에서는 가장 보편화된 어구이므로, 2차적으로 활멸치를 어획하는데는 충분한 실용성이 있다고 보아진다. To catch live anchovies which will be used as bait for skipjack fishing, set net, lift net and purse seine net were tried in Korean coastal waters by the authors. Among them the former two methods showed unsuitable to catch in bulk even though the catch showed good survival. The last showed unsuitable result because of the lack of exclusive fishing boat and skilled fishermen. From the viewpoint of practical use, the authors regarded it may be suitable to improve the traditional boat seine net which are used as major fishing gear to catch anchovies in Korea, so far as Korea is concerned. So we tried to catch live anchovies with partially reconstructed boat seine net and to hold the catch in the creel improved by the authors. Even though the result showed less than 70 percent of survival, slightly worse than other fishing methods, the experimented method showed to be practical in catching the live anchovies intensively.
