The emergence of post-human beings in the 4th Industrial Revolution era led to an epistemological shift in the need for reflection on new relationships with non-human beings, away from human-centered modern humanism. For this reflection, post-human sensibility to empathize and understand the surrounding world is required. In order to cultivate this sensibility, we analyzed the case of art works that can think about and experience the post-human era based on the criteria of 'animal-becoming', 'earth-becoming', and 'machine-being' presented by post-humanist researcher Bridotti. Since the work of art reflects the spirit of the era, we confirmed the positive aspect of the text that can reflect and experience the post-human era. This study is meaningful as a basic study by presenting art works that can be used in art education to improve post-human sensitivity.

In the contemporary American cinematic landscape, there is a distinctive tendency to depict the disturbing ways in which characters with brain damages perceive, remember, and think about the world. Despite its attempts to examine the socio-political implications of these characters' subjectivities, the previous scholarship on this trend of film was limited in being either too pessimistically deterministic or too euphorically optimistic. Critically reading neuroscientific discourses on the brain-damaged subject from the perspective of Giorgio Agamben's critique of biopolitics, this paper explores how the contemporary American cinema of the impaired brain attempts to mediate the neurologically inexplicable affects of those subjects who are in the neurological state of exception and to express their experiences of a becoming-nonhuman. By closely reading Darren Aronofsky's Black Swan and Alejandro $Gonz{\acute{a}}lez$ $I{\tilde{n}}{\acute{a}}rritu^{\prime}s$ Birdman in this regard, I show how the two films, by employing different sets of cinematic free indirect techniques, express the neurologically impaired subject's affective experience of a becoming-nonhuman animal in different ways, and thereby to a more or less extent act as 'profaned' neuro-biopolitical apparatuses.

Based on Deleuze's body aesthetics and from the perspective of 'deterritoraliazation', this study makes an in-depth discussion on the modern fashion design modeling by four visual characteristics: hysteria, visualization, body segmentation and becoming animals. First, hysteria embodies the strong visual effect brought by the deformation and exaggeration of clothing. Second, visualization in fashion shows the elimination or ambiguity of faces, representing the weakening of identity and the prominence of clothing and body. Third, body segmentation represents the deconstruction and reorganization of clothing, and a new way of thinking, as well. Fourth, becoming-animals are manifested in the physical mutation caused by the heterogeneous connection between humans and animals, which brings about the possibility of rethinking the body.

효소는 생물이 만드는 단백질로서 화학반응을 촉진시키는 촉매이다. 현재까지 알려진 효소의 종류는 약 3,000종이 되며 그 숫자는 해마다 증가하는 경향을 보이고 있다. 이 가운데 산업적 응용 가능효소는 150여종이며 상업적으로 생산되고 있는 효소는 60여종이 된다. 효소의 산업적인 이용은 1894년 소화제인 takaamylase가 Aspergillus oryzae의 배양에 의하여 생산된 이래 $\alpha$-amylase와 동물에서 pancreatin, trypsin, chymotrypsin, 사람의 소변에서 urokinase와 식물체에서 protease등이 공업적으로 생산되고 있다. 효소는 화학촉매보다 많은 장점을 가지고 있는데 온건한 반응조건에서 촉매력과 기질특이성(specificity)이 높고 부산물(by-product)이 적다. 그러나 효소의 폭넓은 산업적인 이용은 아직 많이 제한되어 있는데 대체적으로 열, 화학물질, protease, 반응환경등에 의해 쉽게 불활성화되기 때문이다. 이러한 한계를 극복하기 위해 많은 노력을 기울여 왔고 산업적인 필요성에 부응하여 1993년말 이래 미국, New Zealand, Ireland 등지에서 별도의 학술적인 모임이 열렸다. 본 고에서는 현재 식품산업에서 사용되고 있는 효소와 그의 특성, 효소 개발기술 및 국내외 효소시장 현황을 중심으로 개술하고자 한다.

어류는 엷은 피부를 경계로 하여 체액과 삼투압의 차가 있는 수중에서 생활하고 있다. 다른 척추동물과 달리 표피의 살아있는 세포가 직접 외부 환경과 접촉하고 있으며(Hawkes, 1974), 그로 인해 겪게 되는 삼투압의 불균형과 환경적인 유해성분 등에 직면하게 되기 때문에 여러 가지 형태의 특이한 구조를 갖고 있다. 어류 피부계의 미세구조에 대한 연구로는 Brown and Wetting(1970), Zaccone(1983), Jeong and Moon(1994), Lee and Kim(1999) 등의 보고를 들 수 있다. 본 연구는 저서 정착성 어류인 넙치 피부 상피층의 조직학적 관찰을 통하여 추후 이들 어류의 생활환경 및 생리적 변화와 관련된 피부계의 변화양상에 관한 연구의 기초자료를 제공하고자 하였다.

The synthesis of myosin, actin, tropomyosin and troponin in the cultured muscle cells of chick embryo during the differentiation were analyzed. The synthesis of myosin and actin were very active prior to the myoblast fusion while the troponin synthesis became active after the fusion. Tropomyosin was synthesized practically constantly throughout the culture period. Several proteins were detected in the muscle-conditioned medium strongly suggesting that the cells in culture released polypeptides which might act on the membrane of neighboring cells cells to initiate the fusion.

The spermiogenesis of Cipangopaludina chinensis malleata began with the changes of nucleus and cytoplasm. The chromatin in the nucleus began to stack and condense around perinuclear envelope. Axonema (doublet microtubules of 9+2) appeared in the cytoplasm. After this process, the cytoplasm was protruded and the bell-shaped nucleus was located on protruding part of it. The electron dense masses were distributed throughout cytoplasm and lysed or secreted by exocytosis of lysosomal vacuoles. Especially, some mitochondria were migrated by the doublet microtubules of axonema toward nucleus. The axoneme was enclosed by electron dense materials after exocytosis of unnecessary materials for the tail formation. The electron dense masses were released and migrated into the each part through microtubules or axonemal doublet microtubules as the granular particles. These granular particles were containing glycogen. Ultimately, the condensed head developed into helical and neck region into cylindrical shape respectively. The mitochondria which have regular lamellar layers at cross axis became to middle piece, and then spermatozoon was completely matured. Thus, these phenomena showed special processes in spermiogenesis, those were as follows; chromatin in the head was condensed, the head was changed into helical shape, and cytoplasmic materials are migrated and transferred into the each part in the tail by mitochondria and microtubules.

The effects of caffeine on the ATPase activity and Ca uptake of the fragmented sarcoplasmic reticulum isolated from rabbit skeletal muscle were studied. The ATPase activity of the heavy fraction (2,000-8,000xG) was stimulated by caffeine while that of other lighter fractions was not. It is suggested that the enhancement of the ATPase by the caffeine treatment. The Ca uptake of the heavy and middle (10,000-20,000xG) fractions was inhibited by caffeine when measured at the medium Ca concentration higher than 200 nmoles/mg protein, while only that of the heavy fraction was inhibited when measured at the Ca concentration below 200 nmoles/mg protein. Experiments with dicumarol suggested that caffeine inhibits the Ca uptake of the mitochondria as well as that of the sarcoplasmic reticulum and that the inhibition of the Ca uptake by caffeine in the low Ca concentration in the heavy fraction is due to the inhibition of the mitochondrial Ca uptake by caffeine. It appeared highly probable that the potentiation of muscle contraction caused by caffeine is solely due to the inhibition of the Ca uptake by and to the release of the accumulated Ca from the sarcoplasmic reticulum.

If we, as educators, want to put students at the center of learning in science classroom, we must let students express their voices and exercise authority. To do this, we developed a classroom activity about 'Making a pet poster', and then we explored how elementary school students perceived their roles and expressed their authority during this activity. Fourth grade students from an elementary school in the city of Seoul participated in the activity, which was videotaped and recorded. We found that students expressed their epistemic authority differently in small group activities and in whole group discussions. In small group activities, they desired to show their authority as "pet experts" by using and selecting various resources from their everyday lives and transforming those resources into suitable forms in public spaces. Meanwhile, in whole group discussions, participants were classified as either presenters or audience members to verify their authority in regard to the pet poster activity; presenters desired to achieve recognition as "pet experts," and audience members assessed the presenters as "testers." In addition, they expressed authority as teachers by leading the whole group discussions. Based on these findings, this paper suggests the implications for new educational strategies to foster a student-centered learning environment.
