This study aims to analyze illustrations in Wise Life textbooks for the 6th and the 7th elementary school curricula. The 7th textbook has been decreased in the number of illustrations comparing with the 6th one. But illustrations per each page in the textbook and each lesson have been increased in number. In the ratios to a page face, these illustrations for the 6th and 7the textbooks are mostly below 1/4 up to now. Meanwhile, the illustrations of two, 2/3 and 1/3 ratios to a page face have been increased in the 7th textbook, relatively. So, it is considered that the stupid arrangements of these illustrations for 6th textbook have been improved for 7th one. Photos of above illustrations are mostly quadrangular and circular in the 6the and the 7th textbooks. Of above photos, the quadrangular ones in the 7th textbook have been decreased about 10% comparing with ones of the 6th textbook. Although the role of motivation inducement for the illustrations of the 7th textbook is more or less improved, those ones keep below 10% so far. The illustrations of the present textbooks possess backgrounds showing urban and farming lives, in general. On the other hand, it is suggested that the contents of several life styles which are exampled as a fishery village or developing field of oceanic resource would be included in the illustrations of Wise Life textbook, in future.

Polymer-modified paste-applied membrane waterproofing materials has been used as waterproofing materials, e.g. for basement and water tank due to both simple handling and excellent workability. However, as for the polymer-modified paste-applied membrane waterproofing materials, the durability is easy to be degraded by the occurrence and propagation of crack. An aim of this study is to make clear performance of the polymer-modified paste-applied membrane waterproofing materials of which performances are improved through this study. PAE and EVA show the result to be markedly dependent on the condition and period of deterioration. Presence of reinforcement causes the influence to the physical properties of waterproofing materials. In addition, a reinforcement effect of non-woven fabric on cracking can be expected.

Two subjects, Science teaching method and Study of the subject matters, are established to let students have the ability to teach the elementary science. It is an overwthelming view that Science teaching method course are merely divided into the above-mentioned two subjects by the elevation from the junior college to the senior one. But the authors discussed this theme on the junior college to the senior one. But the authors discussed this theme on the viewpoint that Study of the subject matters, newly established, is the result reflecting the significance of the elevation, not just the division of Science teaching method course inaugurated in the junior college period. The subject matters in the elementary school should include the fundamental concepts to attain the goal of the subject. That is, the subject matters should include the learning contents with the educational significance. Therefore, Study of the subject matters is defined as studying what these contents may signify educationally. From these points of view, Study of the subject matters is: 1) the study intended for the subject matters of the elementary school. That is ① what the fundamental concepts are, ② how they are related each other, ③ what their educational significance is. 2) to study the educational significance of the other subject contents. 3) a study for establishing the pertinent goal and selecting the subject matters to attain this goal when the educational conditions, such as the actual state and environment of children, are given. The authors discussed about article 1) in this paper.

This study was investigated the effects of various system parameters on the absorption of carbon dioxide into absorption solution. An aqueous potassium carbonate solution was used as a chemical absorbent in order to figure out the effect of chemical reaction. For this purpose, the chemical analysis of potassium carbonate solution was performed. The changes of pressure, temperature, K₂CO₃solution flow/feed gas ratio and solution concentration in the absorber and the changes of pressure and temperature in the stripper were also analyzed. The analysis result shows that K₂CO₃ concentration in potassium carbonate solution was 99.6%. The optimum pressure was found to be 27.0㎏/㎠ and the optimum temperature was to be 68℃, the optimum concentration of potassium carbonate solution was to be 26.0wt% in the absorber. The CO₂ leakage decreased with the increment of the K₂CO₃ solution flow/feed gas ratio. But the H₂ leakage in the CO₂ product increased at or above the K₂CO₃ solution flow/feed gas ratio of 1.10. This H₂ leakage induced by the loss of ammonia production. The effects of the changes of the operation condition of the CO₂ stripper to the K₂CO₃ conversion are as follows. The K₂CO₃ conversion decreased as the pressure decreased. The K₂CO₃ conversion increased as the temperature increased. However, increasing the temperature without decreasing the pressure did not bring positive effect. The optimum pressure was found to be 0.45㎏/㎠.

Background and Objectives: Transforming growth factor-α (TGF-α) and epidermal growth factor (EGF) are polypeptides which interact with the epidermal growth factor receptor (EGFR) to produce their biological effects. The aim of the present investigation was to elucidate the immunolocalization of TGF-α and EGF in normal human skin, hypertrophic scar with skin graft on soft tissue defect, and postburn hypertrophic scar without graft. Methods: The data presented in this paper focused attention on differences of expression between two kinds of hypertrophic scars in relation to skin graft using immunohistochemistry. Formalin-fixed and paraffin-embedded tissues from 3 normal skin tissues, 3 hypertrophic scars after skin graft and 8 postburn hypertrophic scars without graft were immunolabelled with antibodies directed against TGF-α and EGF. Results: In normal epidermis of skin, strong TGF-α immunoreactivity (IR) was observed in all epidermal layers except the stratum (S.) basale, whereas EGF was immunopositive in a few cells over all epidermal layers. The staining for TGF-α was found in cell membrane, and EGF was seen either diffuse cytoplasmic or peripheral part of cells in normal epidermis. In hypertrophic scar after six months postoperation, TGF-α IR was observed in the upper part of S. spinosum and S. corneum, whereas EGF was diffusely expressed in the S. spinosum, also its intensity was slightly increased compared to normal skin. In hypertrophic scar without skin graft, very strong expression of EGF was detected in the S. spinosum and S. corneum, and intensity of EGF was increased when compared to normal skin and postoperative hypertrophic scar. EGF and TGF-α coexisted in the cells of S. spinosum in normal skin as well as hypertrophic scars. Double-labeled cells were increased in postburn hypertrophic scar compared to normal skin and postoperative hypertrophic scar. In addition, intensity of EGF and TGF-α double IR was the strongest in postburn hypertrophic scar. Conclusion: These results indicate that EGF may have a more complex regulatory role not only in the early stages of wound healing but also in hypertrophic scar.

Over the past 20 years, research on students' conceptual development of science concepts has begun to inform educators about the roles that prior knowledge and experiences play in the development of conceptual understandings. Whereas many initial studies focused on identifying and cataloging naive of misconceptions, more recent research has focused on how student concept development research can inform teaching practice and curriculum design. In this study, we investigated children's (ages 11∼12) spontaneously constructed or naive understanding of the particulate nature of matter prior to any formal instruction in the domain. Thirty students were interviewed concerning their understanding of the macroscopic and microscopic properties of the states of matter(solid, liquid, and gas), as well as their macro/microscopic understanding of phase changes and dissolving. Children expressed ideas about states of matter which were categorized as macrocontinuous, macroparticulate, or microparticulate. Furthermore, a substantial number of the children provided explanations of properties and processes which were consistent with those beliefs. These children's beliefs about matter were not fully and consistently developed across the spectrum of substances from continuous solids to particulate solids to liquids to gases. We speculate that children first develop local frameworks particular to different classes of substances and then slowly expand these frameworks to include a wide range of substances and their properties as well as such processes as melting and freezing.

연구배경 : 흡연이 폐기종. 만성 기관지염등의 만성 폐쇄성 폐질환을 유발한다는 사실은 잘 알려져 있으며 이러한 호흡기 질환의 초기에는 직경이 2㎜ 이하인 소기도에 폐쇄성 병변이 선행하는 것으로 추정되고 있다. 이러한 소기도 폐쇄를 나타내는 폐기능 검사소견의 이상 에 호중구에서 분비하는 산화물(oxidant)이 관여하는가를 알아보고자 호흡기에서의 폐기능검사와 말초혈액의 호중구에서 분비하는 산화물을 측정하여 양자간의 관련성 여부를 조사하였다. 방법 : 소기도의 폐쇄지표로는 폐기능검사상 Vmax 50/FVC, Vmax 75/FVC, FEF_(25~75%)를 이용하였고 호중구에서 분비하는 산화물은 분리한 호중구에 luminol을 섞어 phorbol myristate acetate (PMA)로 자극하거나 PMA 대신 media를 대신 넣어 자극했을때와 안했을때의 luminol enhanced cheiluminescence(LECL)을 luminometer를 이용하여 측정하였다. 결과 : 1) 말초혈액 호중구를 분리하여 LECL을 측정한 결과 호중구의 PMA자극여부에 관계없이 흡연군에서의 LECL은 비흡연군에 비하여 유의하게 증가되어 있었다.(p<0.05). 2) 폐기능 검사에서는FVC가 흡연군에서 오히려 비흡연군보다 높았고(p<0.05) 소기도 폐쇄의 지표중의 하나 Vmax 75/FVC는 흡연군에서 유의하게 낮았다(p<0.05). 3) 흡연자들에서 각각의 폐기능 검사와 그들의 나이, 흡연력(pack-years, cigars per day), 호중구의 LECL등과의 상관관계는 없었다. 4) 그러나 폐기능검사 항목중 예측치의 85% 이하인 것이 3개 이상인 4명의 흡연자에서는 이들의 FEF_(25~75%), Vmax 50/FVC, Vmax 75/FVC와 호중구를 PMA로 자극시 LECL과는 유의한 역상관관계가 있었다. 결론 : 이상의 결과로 흡연자의 호중구는 감작되어 있다가 어떠한 자극에 의해서 oxidant를 많이 분비하여 본실험에서와 같이 PMA 자극시 LECL이 증가되며, 증가된 LECL이 어떤 경우에는 소기도 폐쇄의 원인이 될 수도 있을 것으로 생각된다. 앞으로 흡연자의 혈중에 호중구를 감작시키는 물질이 무엇인지에 대한 연구가 진행되어야 할 것으로 사료된다. Background : Cigarette smoking is firmly established as the primary environmental risk factor associated with chronic obstructive pulmonary disease (COPD) including pulmonary emphysema and chronic bronchitis. The development of COPD is known to be preceeded by small airway obstructive discase. Cigarette smoking induces lung phagocyte (macrophage and neutrophils) recruitment, and that neutrophil and macrophage have increased oxidative function in cigarette smokers. So we have investigated the possible relationship between neutrophil activation and spirometric parameters in asymptomatic young smokers. Methods : Oxidant generation by circulating neutrophils were measured by luminol enhanced chemilumines-cence(LECL) and lung function test were performed at the same day in 24 asymptomatic young smokers and 24 non-smokers. Results : 1) LECL of the peripheral blood neutrophils were significantly increased in smokers during both in non-stimulated cases and in stimulated cases with phorbol myristate acetate (PMA) than in non-smokers. 2) In pulmonary function test. Vmax_(75)/FVC was significantly lower and FVC was higher in smokers than in non-smokers. 3) In 4 smokers of those whose more than three spirometric parameters were below 85% predicted, there was a inverse relationship between PMA-activated neutrophil LECL and FEF_(25∼75%), Vmx 50/FVC, Vmax 75/FVC. Conclusion : Our findings indicate that cigarette smoking can increase the reactive oxidants from both non-stimulated and PMA stimulated peripheral blood neutrophils and this increased LECL appears to be associated with amall airway obstruction in some cases.
