아버지의 학력, 자녀양육에 대한 부부 일치도 지각 및 다중지능과 유아의 다중지능과의 관계 연구

장영숙,노운서 한국영유아보육학회 2004 한국영유아보육학 Vol.0 No.39

본 연구는 아버지의 배경변인인 학력과 직업, 아버지의 심리적 변인인 아버지가 지각한 자녀양육에 대한 부부일치도, 그리고 아버지의 다중지능이 유아의 다중지능 발달에 어떠한 영향을 미치는지를 살펴보았다. 연구결과, 아버지의 학력에 따라 음악 지능과 신체 운동 지능 영역을 제외한 여섯 영역의 유아의 다중지능 발달에 차이가 있었으며, 아버지의 직업에 따라서 유아의 다중지능 발달은 차이를 보이지 않았다. 또한 음악지능, 논리수학지능, 언어지능, 대인관계 지능, 개인이해 지능, 자연탐구 지능에서 자녀 교육에 대해 부모간의 의견이 일치한다고 아버지가 지각할 때. 유아의 다중지능이 통계적으로 유의미하게 높게 나타났다. 유아의 다중지능의 여덟 영역과 아버지의 다중지능의 여덟 영역간의 상관관계를 살펴본 결과, 모든 영역에서 아버지의 다중지능과 유아의 다중지능 간에 매우 유의미한 상관이 있는 것으로 나타났다. This research analyzed how young children's multiple intelligences(MI) is related to their fathers' education, perception on couple's agreement for parenting style, and multiple intelligences(MI). Subjects were 259 preschool children and their fathers in Kwangju. Data were analyzed by ANOVA, Pearson's correlation, and multiple regression. The results of the study were as follows: First, young children's multiple intelligences showed significant differences according to father's education in the six areas of multiple intelligences, which is logical-mathematical intelligence, linguistic intelligence, spatial intelligence, interpersonal intelligence, intrapersonal intelligence, naturalist intelligence. Second, young children's multiple intelligences showed significant differences according to fathers' perception on couple's agreement for parenting style in the following five areas: musical intelligence, logical-mathematical intelligence, linguistic intelligence, interpersonal intelligence, intrapersonal intelligence. Third. correlation analysis between children's multiple intelligence and fathers' multiple intelligence showed that eight areas of intelligence were significantly correlated each other. In addition, young children's intelligence in each area of multiple intelligences was associated with their fathers' intelligence in that area.

Naphthoquinone diazide 유도체의 합성과 특성 연구

홍장후,김운겸 서울産業大學校 2002 논문집 Vol.53 No.1

Naphthoquinone diazide derivatives members of quinone diazide compound that are utilizable as photosensitive polymer material were synthesized, and photoresist were prepared by mixing these derivatives with a matrix resin at various weight ratios. Photosensitive characteristics of photoresist were studied by examining UV and IR, relative sensitivity using a Gray scale method, and SEM to analyze if they can be used as photosensitive material in printing process. Experimental results showed that, by UV, NQD derivatives were photo-converted and developer-soluble photoresist were produced. The mixing ratio of 1 : 4(by mass) of NQD+ ballast and m - cresol novolak gave rise to the highest dissolution rate. In addition, photoresist obtained at this condition resulted in the most superior sensitivity and contrast.

천연 Gum의 Rat 피부조직에서의 영향 연구

홍장후,김운겸 서울産業大學校 2002 논문집 Vol.53 No.1

Gum Films were prepared by solution blending in the weight ratio of natural gums(Xanthan, Locust bean and Guar) for the purpose of useful bio-implants. The possibility of bio-implants, which prepared from natural gums as a skin substitute was evaluated by measuring biodegradability. This biodegradable films were inserted in the back of rats and their of biodegradability were investigated by hematological change evaluation as a function of time to the bio-transformation. These values of biodegradable films, which prepared from natural gums measured in this study were some stable results at short period with those of ideal skin bio-implants.

Cu/ZSM-5촉매에 대한 NO 및 NH₃TPD 연구

홍장후,정택서,김운겸 서울産業大學校 1996 논문집 Vol.44 No.1

The effect of catalyst acidity and of its absorption property on the catalytic have examined for caption exchanged ZSM-5. Adsorption property of the NH₃and NO over HZSM-5 and Cu/ZSM-5 catalyst was investigated by NH₃,NO TPD. Also, room temperature adsorption and temperature-programmed desorption(TPD) of NO over a Cu/ZSM-5 catalyst active for NO decomposition were investigated. Even at 25℃ N₂O and N₂ were observed as reaction products during NO adsorption but they ceaced when NO adsorption was completed. During NO TPD N₂O , NO and O₂ desorptionpr peaks were observed. A oxygen desorption peak was detected at Ca360 ℃. No decompositive was detected without copper present. NO TPD was also collected over reduced and oxidized catalysts.

ZSM-5제올라이트 합성에 관한 연구

홍장후,정택서,강경묵,김운겸 서울産業大學校 1998 논문집 Vol.47 No.1

A pentasil zeolite. ZSM-5 was succesfully synthesized at low temperature and atmospheric pressure. The experinments were carried out in four different methods 1, 2 and 3 depending on the concentrations of water, organic template. TPABr (tetrapropy-lammonium bromide) and the presence or absence of seed, the overall molar composition used in this study was 7.83 Na₂O-0.25 Al₂O₃-100SiO₂-xTPABr-yH₂o where x is 1 and 3 mol, and y is 3000mol, 3500mol, and 4000mol. 2³factorial experiments were performed with the results of kinetics studies Na₂O, TPABr and H₂O as main factors, The result showed that the concentration of H₂O is the most important.

Background: It is doubtful that aging causes deteriorated glucose metabolism and insulin resistance of skeletal muscle. Some researchers had different results about it. So we have studied the mechanism responsible for the abnormal glucose tolerance associated with aging in rapidly growing and matured rats. Materials and Methods: Animals were used S.D. rats. Growing rats were 7 weeks old (BW: 160-190 gm) and matured rats were 28 weeks old (BW: 420-525 gm). Results: Fasting blood glucose and plasma insulin levels were significantly elevated in matured rat compared with growing rats. And during oral glucose tolerance test the glucose level was also significantly elevated in matured rats. These results confirmed an insulin resistant state of aging. Insulin levels at 30 minutes of oral glucose tolerance test was significantly elevated in growing rat. But at 120 minutes it was maintained at higher level in matured rats than in growing rats. It suggested the possibility of increased insulin secretion by initial stimulation of beta-cells in growing rats, and increased secretion and decreased catabolic rate of insulin in matured rats. Glucose uptake rate of soleus muscle in matured rats was lower than that of growing rats, but the difference was not statistically significant. The dose(insulin)-responsive(glucose uptake) curve of soleus muscle was only slightly deviated to the right side. Conclusion: Glucose metabolism of rat skeletal muscle was worsened by aging. The data of glucose uptake experiments suggested the possibility of insulin resistance of skeletal muscle in matured rats, but the mechanism of insulin resistance of skeletal muscle need further studies.

混成 回路를 使用한 廣範圍 周波數 分周器에 관한 硏究

金將起,宋洛雲 단국대학교 1980 論文集 Vol.14 No.-

When we use a monostable Multivibrator as a frequency divider, there is always a upper frequency limit due to the recovery time circuit. To solve this problem in this paper, we coupled a chain of bistable flip-flops to the Monostable Multivibrator. Then the frequency division ratio can be increased while maintaining the variability of the Monostable Multivibrator as a frequency divrider.

홍장후,신현진,김운겸,강경묵 서울産業大學校 1999 논문집 Vol.49 No.2

PVA/Algin blend films were prepared by solution blending method for the purpose of useful biodegradable polymer. Characteristics properties of blend films such as DSC, Elongation, Tensile strength and Morphological changes by SEM were determined. Tensile strength and Elongation were rapidly reduced as increasing the blend ratio of Algin. Blend films were found that phase separation was occured as more than 25wt% increasing the blend ratio of Algin. Blend films were observed to be less partially compatibility than 10wt% increasing the blend ratio of Algin by DSC, mechanical properties and SEM Also, Blend films at the laboratory soil test(Pot Test) were completely degraded in months with four kinds of soils by microganisms.
