정현희,최경순 동의대학교 생활과학연구소 2000 生活科學論集 Vol.4 No.-

This study was to investigate the following research questions. (1) Are there any gender differences in the mother's socialization-patterns and child's self-concept? (2) Is there any relationship between mother's socialization-patterns and child's self-concept? (3) Is child's self-concept influenced by the mother's socialization-patterns and child's gender? The subjects of this study were 235 boys and 207 girls attending elementary schools in Busan. Lee, Kyung-Hee's questionnaires(1993) on mother's socialization patterns and Kim, Ki-Jung's questionnaires(1984) on child's academic self-concept and Kim, Hee-Kyung's questionnaires(1990) on child's physical, home, social self-concept were used. The results were as follows: 1)The mother's imperative mode for boys differed significantly from that for girls. Boys perceived mother's socialization-patterns as more imperative. And boy's physical self-concept and academic self-concept differed significantly from girl's. Boy had higher scores than girl in physical self-concept and academic self-concept. 2)There were significantly correlations between mother's position-oriented mode and boy's self-concept, between mother's poison-oriented mode and boy's self-concept. 3)The mother's poison-oriented mode was the predictor variable influencing on child's academic self-concept. And the mother's position-oriented mode and the mother's person-oriented mode were the predictor variables influencing on child's home self-concept.

이경옥,Kanaoka, Chikao,황우현,박영옥 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.6

고온에서 집진 성능이 우수하고 저렴하게 사용할 수 있는 합성섬유 여과포의 코팅기술을 개발하기 위한 내열성 코팅 실험을 수행하였다. 코팅된 여과포의 내열실험을 300℃ 및 400℃에서 수행한 후, 여파포의 무게변화, 두께변화, 수축률을 측정하여, 내열 특성을 측정하였다. 가열 전후의 무게 변화를 측정한 결과 ARABON 여과포는 300℃에서 36.3% 감소하였고, CARBON 여과포는 38.9%로 감소하였으며, 수축현상은 ARABON이 13.7%로 약간 변화되었지만 CARBON 여과포는 21.7%로 조금 더 변화되었다. 고온에서 합성섬유 여과포의 내열성능을 나타내기 위하여 변화지수, CI를 정의하여 사용하였다. 300℃와 400℃에서 CARBON 여과포의 가장 우수한 코팅물질은 Al(NO₂)₃이었다. This study has been accomplished by the coating experiments to develope the synthetic fabrics with thermal resistance, which are the economic and efficient filter at high temperature. The thermal resistance of the fabric filter was experimentally determined by the changes of the weight, thickness, and contraction of the coated and non-coated filters. The tested temperatures were 300℃ and 400℃. The weight losses of the ARABON and CARBON fabrics are 36.3% and 38.9%, and the contractions are 13.7% and 21.7% at 300℃ compared to 400℃ respectively. The change index, Cl, was defined and used for providing the thermal resistant information of the tested fabrics. The most coating material is Al(NO₂)₃ for CARBON fabrics at 300℃ and 400℃.

The purpose of this research is to provide the fundamental information about mathematics classes based on activism by analyzing mathematical thinking and mathematical creativity students display while solving tasks based on activism. A case study was conducted with two male middle school 2nd graders and two female middle school 2nd graders as subjects, and was composed of a total 8 experimental teaching sessions, each lasting 120 minutes. As result of analyzing mathematical thinking and mathematical creativity students display based on Polya's four Phase of problem solving process/ the type of mathematical thinking were intuitive insight, systematization of information, spatialization/ visualization, mathematical abstraction, inductive reasoning, deductive reasoning, generalization/application, reflective thinking and they were usually displayed collectively, but also independently. 8 types of mathematical thinking at the question understanding phase were displayed, 19 ones at the question understanding phase, 24 ons at the plan-execution phase, 9 ons at the reflection phase. The type of mathematical creativity were fluency, fluency, originality, ingenuity, and they were displayed collectively, but also independently. At the question understanding phase, the type of mathematical creativity were not displayed, 2 types of mathematical creativity at the plan-execution phase were displayed, 3 ones at the plan-execution phase, 4 ones at the reflection phase.

This study aimed to find out the method of rational arrangement of kitchen utensils and appliances and the capacity of them. Questionnair was distributed to families of 469 of middle school students. We studied the quantity and the kinds of kitchen utensils and its places for storage. The results were as follows. 1.Storage places: 1) The storage places of utensils for preparing, serving, and cooking were relatively appropriate. 2) Being daily using home set placed in the showcase outside of kitchen work centers, houswives had to walk extra distance. 3) Precious dishes for guests and electric appliances were exbited in the showcase for decoration. 2.The capacity of kitchen cabinets: 1) The capacity of upper cabinets was 0.450m3 (0.047m3 for preparing center, 0.085m3 for sink center, 0.104m3 for cooking center, 0.028m3 for serving center and 0.182m3 for using space). 2) That of base cabinets was 1.08m3 (the length of base cabinets 2.30m× depth of them 0.55m× height of them 0.85m). So, 1.53m3 capacity is suggested for 5 middle-class family.

Among the radiographs for temporomandibular joint, transcranial radiograph is widely used for screening and diagnosing temporomandibular disorder because it has sharp image and it is easy to take. This study was performed to compare condylar position and image sarpness in standard and individually corrected transcranial radiographs using Accurad-200 headholder. Submentovertex view, Reverse-Towne view, Standard and individually corrected transcranial radiographs of 45 university students who were randomly selected were traced, measured and analyzed. The results were as follows : 1. The means of condylar axes and lateral slopes were 16.8˚ and 22.5˚ respectively. There were no differences between male and female or right and left side. 2. Individually corrected radiographs showed smaller posterior joint space and larger anterior joint space than standard radiographs, but superior joint space did not show a statistical difference between standard and individually corrected radiographs. 3. While a large number(42.2% ) of the standard radiographs showed concentric condylar position, lots of(57.8) condylar positions were retropositioned in the individually corrected radiographs. 4. The image sharpness was inferior in the individually corrected radiographs to that of the standard radiographs.

급속응고된 N-type Bi₂Te_(2.75)Se_(0.15) 열전재료의 미세조직과 열전특성에 미치는 압출비의 영향

김태경,이상일,임종호,손현택,김택수,천병선 대한금속재료학회 2005 대한금속·재료학회지 Vol.43 No.1

The n-Type thermoelectric compounds of Bi₂Te_(2.75)Se_(0.15) doped with 0.1 wt% SbI₃ were fabricated by gas atomization process and extruded under ratio of 16:1 and 28:1 at 450℃. The effect of extrusion ratio on the microstructures and thermoelectric properties were investigated by a combination of microscopy, XRD and thermoelectric properties. Grains of extruded bars are smaller than those of heated powder at extrusion temperature (450℃) due to the dynamic recrystallization but with increasing the amount of plastic deformation, grains of specimen extruded with 28:1 were slightly coarse. The compressive strength of hot extruded bar under 28:1 is 160 MPa and with decreasing the extrusion ratio to 16:1, the value is 250 MPa. The Seebeck coefficient a and electrical resistivity p were decreased with increasing ratio, while thermal conductivity x was increased. this results from decrease of carrier scattering and increase of carrier mobility. Extruded bar under ratio of 16:1 shows the higher value of figure of merit (Z=2.50x10^(-3)/K) than that of 28:1 (Z=2.07x10^(-3)/K). (Received June 24, 2004)
