      • 2015 과학과 교육과정에 따른 초등 5~6학년군 과학과 교과용 도서 중 생명 영역의 특징

        임채성,배진호,박지환,신원섭,신연옥,박형민 한국초등과학교육학회 2019 한국초등과학교육학회 학술대회 Vol.76 No.-

        2015 과학과 교육과정에 따른 5~6학년 과학 교과용 도서에서 생명 영역에 해당되는 단원은 ‘다양한 생물과 우리 생활’, ‘생물과 환경’, ‘식물의 구조와 기능’, ‘우리 몸의 구조와 기능’이다. 2009 교육과정과 달리 2015 교육과정에서는 ‘식물의 구조와 기능’과 ‘우리 몸의 구조와 기능’ 단원은 6학년으로, ‘다양한 생물과 우리생활’과 ‘생물과 환경’ 단원은 5학년으로 이동하였다. 5학년 1학기 ‘다양한 생물과 우리생활’ 단원은 11차시로 구성하였다. 2009 교육과정에 비해 2015 교육과정에서는 다양한 도구를 사용하여 균류와 원생생물을 직접 관찰하는 활동을 강조하고, 특히 ‘현미경 사용법 익히기’를 탐구활동으로 제시하였다. 그리고 다양한 생물이 우리 생활에 미치는 영향과 첨단 생명과학의 이용된 사례의 조사 탐구활동을 강조하였다. 따라서 학생들이 돋보기, 실체현미경, 광학현미경 등 생물을 더 심층적으로 탐구하는 데 필요한 도구 사용 능력을 향상시킬 수 있도록 교과서를 구성하였다. 또한 학생들이 직접 스마트기기를 이용하여 조사 탐구활동을 할 수 있게 구성하였다. ‘생활과 과학’ 차시에서는 학습한 내용을 실생활과 연계하여 과학적 문제해결력을 기르도록 구성하였다. 5학년 2학기 ‘생물과 환경’ 단원은 11차시로 구성하였다. 2009 교육과정에 따른 교과서에서는 주로 육상 생태계 구성요소 중심으로 삽화를 제시했으나, 2015 교육과정에 따른 교과서에서는 육상 생태계와 수중 생태계의 균형을 고려하여 삽화를 제시하였다. 또한, 기존의 ‘오염 물질이 무씨 발아에 미치는 영향 관찰하기’ 탐구 활동은 학생들에게 오개념을 심어줄 가능성이 높아 삭제하였고, 대신 2015 교육과정에서 성취기준 해설에서 제시된 바에 따라 환경 오염으로 인한 생물의 피해 사례 중심의 조사하기 활동으로 변경하였다. 6학년 1학기 ‘식물의 구조와’ 기능 단원은 11차시로 구성하였다. 2009 교육과정과 비교하여 달라진 점은 뿌리의 기능을 알아보는 실험에서 양파에 새 뿌리를 자라게 하여 실험을 하도록 하였으며, 광합성 산물을 확인하는 실험에서 알코올램프를 이용한 중탕 가열로 알코올의 온도를 올리는 대신 뜨거운 물을 사용하여 알코올의 온도를 올리는 것으로 바꾸었다. 잎에 도달한 물의 이동을 알아보는 차시는 탐구학습모형을 적용하여 스스로 가설을 세우고, 실험을 설계해 보는 활동으로 바꾸어 과학적 문제해결력을 기르도록 하였다. 6학년 2학기 ‘우리 몸의 구조와 기능’ 단원은 11차시로 구성하였다. 기존의 뼈와 근육 모형만들기와 호흡 모형 부분은 학생들에게 오개념을 심어줄 가능성이 높아 삭제하였고, 배설 원리를 알아볼 수 있는 역할놀이를 추가하였다. 또한 생활과 과학 차시에서는 학습한 내용을 실생활과 연계하여 문제를 해결하는 방식으로 과제를 제시하였다.

      • 과학 학습 유형에 따른 초등학생의 과학 수업에 대한 감성 상태와 기억 유형에 관한 연구

        임채성,김분숙 부산교육대학교 과학교육연구소 2001 科學敎育硏究 Vol.26 No.-

        To investigate the relationship between emotional states of the 6th grade children and types of memories, we analyzed the memories on school science with regard to the emotional states of them, then classified them according to the instructional modes used: experimental, observation, discussion, and lecture. The results are as follows. First, the children displayed much more positive emotional states for the instructional mode of observation that they could actively participate through hands-on activities rather than teacher-directed instruction. Children had more memories when they perceived the instruction positively than they did negatively. Second, the amount of memories on the instructional modes of discussion, experiment, observation which primarily let learners participate actively was much higher than that of lecture which was teacher-directed. Especially, in the modes of observation and experiment which emphasized hands-on activity of children, higher amount of semantic, episodic, emotional memories appeared. Finally, for the degree of persistence of memories on each instructional mode, those of semantic, episodic, and emotional memories were decreased from immediate to seven days of the instruction implemented. These findings provide a basis for understanding the roles of emotion in learning science. The results also highlight the need for teachers to provide experiences and to create environments which encourage the positive emotional states of learners when teach science subjects.

        Knowledge Transfer between Users and Producers in the Accumulation of Technological Capability

        임채성 기술경영경제학회 2005 Journal of Technology Innovation Vol.13 No.2

        This study reveals that the user industry has a limited role in being a source of technological capability in the case of the machine tool industry in Korea where the user industry is relatively more advanced than other capital goods industries. This study examines the sources of technological capability in terms of migration of workforces and flow of product development knowledge. Although the capital goods sector is generally regarded as being the sector where user-producer interaction is important, the user industry is not the seed-bed of technological capability for machine development. Users and producers interact in terms of expressing “needs”, mainly in the form of specifications. As a result of receiving unique specifications from users, the producer learns to react by making specific customised special purpose machines. The user’s specification could include information on the imported machine originally used.When confronted with technical problems in developing a new machine, the producer accesses foreign sources of knowledge. This study’s finding reveals that users of special purpose machines have a significantly clearer role in providing specifications than do users of general purpose machine tools. Most intensive interactive learning between users and producers in the production process is found in special purpose machine tools. From the empirical findings, policy implications are discussed.

        The difference in the dose of vasoactive drugs and rocuronium according to the general anesthesia method during open gastrectomy

        임채성,신용섭,윤석화,이정언,윤희석,오민혜 대한마취통증의학회 2013 Anesthesia and pain medicine Vol.8 No.2

        Background: Recently, balanced anesthesia (BA: halogenated volatile anesthetics + remifentanil) has been useful for abdominal surgery. The authors therefore performed a retrospective study about the difference in the dose of vasoactive drugs and rocuronium according to the general anesthesia type. Methods: BA was compared with inhalational anesthesia (IA:halogenated volatile anesthetics + N2O) and total intravenous anesthesia (TIVA: propofol + remifentanil). The records of a total of 415 patients (IA : TIVA : BA = 126 : 157 : 132) who received open gastrectomy between 2004 to 2010 were analyzed. The types of vasoactive drugs and dosage as well as infusion time were calculated. The total amounts of vasoactive drugs were scored by two different methods. Infusion drugs were scored as 30 points,whereas bolus drugs were scored as 5 points. Drug score is the total sum of each score, where each drug score point split either into Plus or Minus. Plus means raising the blood pressure whereas Minus means the opposite. For rocuronium dosage, a total of 286patients (IA : TIVA : BA = 89 : 78 : 119) who met the criteria were enrolled, and this formula was used (total rocuronium/weight/time,μg/kg/hr). Results: The BA group showed a lower (P = 0.01) Minus score (1.8 ± 4.0) compared to the IA group (3.6 ± 5.2). Less amount of rocuronium (P = 0.001) was administered in the BA (327 ± 72μg/kg/hr), compared to the IA (368 ± 93 μg/kg/hr) and TIVA (356± 81 μg/kg/hr). Conclusions: BA seems to require less hypotensive agent and rocuronium compared with IA and TIVA for open gastrectomy. But,well-designed prospective studies are required.

        말채나무 추출물의 α-amylase 저해 활성

        임채성,이해익,김용무,이춘영,이위영 한국응용생명화학회 2005 Journal of Applied Biological Chemistry (J. Appl. Vol.48 No.1

        α-Amylase inhibitor is used to control blood glucose level by inhibiting starch digestion in the small intestine and delaying the absorption of glucose. In this study, we investigated the inhibitory effect of the ethanol extracts from more than 1400 species of plants against α-amylase with the aim of developing a new α-amylase inhibitor. In the results, Cornus walteri extracts showed the highest inhibition activity. The inhibitory effect of Cornus walteri extract on the carbohydrate hydrolysis enzymes has different sensitivities against α-amylase from salivary and pancreatin and against α-glucosidase from yeast and porcine small intestine. In the study of inhibition kinetics of α-amylase and α-glucosidase, Cornus walteri extract showed competitive inhibition against salivary and pancreatin while showing the combination of uncompetitive and noncompetitive inhibition against α-glucosidase. The Cornus walteri extract was stable at acidic and thermal conditions. As for the blood glucose and body weight levels of Cornus walteri extract, we confirmed anti-hyperglycemic and anti-obesity effects. Also, in the investigation of the mRNA lever, Cornus walteri extract upregulated the level of GLUT4 mRNA in the quadriceps muscle.

        韓日兩國의 鐵道經營과 構造改革

        임채성 한일경상학회 2004 韓日經商論集 Vol.29 No.-

        Although National Railroad in Korea and Japan played roles of the basic means of transportation during the rapid economic growth era. However, after a highways were opened for traffic, the predominancy of National Railroads in traffic markets was lost for the intense competition with other means of transportation. In order to stop the fall of such competitive power, management improvement efforts were carried out repeatedly. But, it was only that a management actual result got worse. Unless structural reform was carried out resolutely any longer as a result, it became impossible to establish black-figures management. In the concrete method, the railroad structural reforms of Korea-Japan both countries showed different patterns. As the result of the Japanese government's advancing privatization in 1987, new JR 7 companies could attain management stability. On the other hand, Korean railroad reform passed through trial and error over 20 years with the policy authorities' non-consistency. Promotion of structural reform stirred up the sense of impending crisis of labor union, and made capital-and-labor conflict amplify rather. The management view of Korean Railroad Corporation(KRC) is also by no means bright. The instability of management became large by opening of traffic of KTX. From now on, according to aging of population, it is predicted that railroad demand will stagnate in the long run. At such a point, KRC has to advance diversification positively like JR, and to develop the new source of an income. As first-thing-to-do conditions, KNC must build the management organization by professional manager and stabilize management labor relation urgently.

        Paenibacillus donghaensis JH8에서 세포외 Xylanase의 특성

        임채성,오용식,노동현,Lim, Chae-Sung,Oh, Yong-Sik,Roh, Dong-Hyun 한국미생물학회 2011 미생물학회지 Vol.47 No.1

        Xylanase is a class of enzymes that hydrolyze the linear polysaccharide ${\beta}$-1,4-xylan into xylose. This enzyme is applied in the process of paper making and may be used for the process of biofuel production in the future. The Paenibacillus donghaensis JH8, isolated from Donghae deepsea sediment and reported as a novel bacterium, was known to degrade xylan and its xylanase was characterized in this study. The enzyme was maximally induced in the presence of 0.1% xylan. The production of xylanase was started at early logarithmic phase and reached about 55 miliunit at stationary phase of growth. The optimal temperature and pH of extracellular xylanase were found to be $40^{\circ}C$ and pH 6.0, respectively. The activity of xylanase was inhibited by the presence of $Ca^{2+}$, $Mn^{2+}$, $Fe^{2+}$, $Cu^{2+}$, $Al^{3+}$ or EDTA, and activated by $K^+$, $Ag^+$ or DTT. This xylanase was stable at $40^{\circ}C$ for 120 min, but lost almost their activity in 30 min at $60^{\circ}C$. Zymography analysis of concentrated culture supernatant revealed one major band at 42 kDa and two faint bands at 68 and 120 kDa. Xylanase는 선형복합다당인 ${\beta}$-1,4-xylan을 xylose로 가수분해하는 효소의 한 종류이며, 종이제조공정에 응용되고 미래에 바이오 연료의 생산에 사용 될 수 있다. 동해 심층 퇴적물로부터 신종세균으로 보고된 Paenibacillus donghaensis JH8은 배지중의 xylan을 분해한다고 알려져 있으며, 여기에서는 이 효소의 특성을 조사하였다. 효소는 0.1% xylan 존재에서 최고로 유도되었으며, xylanase의 생산은 초기 대수성장기에 효소를 생산하기 시작하여, 정지기에서 약 55 miliunit에 도달하였다. 세포외성 xylanase의 최적온도와 pH는 각각 $40^{\circ}C$와 pH 6.0이였다. Xylanase의 활성은 $Ca^{2+}$ 및 $Mn^{2+}$, $Fe^{2+}$, $Cu^{2+}$, $Al^{3+}$, EDTA의 존재에 의해 억제되었고, $K^+$, $Ag^+$, DTT에 의해 활성화되었다. 이 xylanase는 $40^{\circ}C$에서 120분간 활성을 유지하며 안정하였지만, $60^{\circ}C$에서는 30분에서 거의 모든 활성을 잃어버리는 특성을 보여주었다. 농축된 배양 상등액의 zymography 분석시 42 kDa의 주 밴드와 68과 120 kDa에 두 개의 아주 희미한 밴드를 나타내었다.
