저 SiO2 저 FeO 소결광의 성장에 관한 연구

양철기,조룡환,배석환 대한금속재료학회(대한금속학회) 1984 대한금속·재료학회지 Vol.22 No.10

For the purpose of low energy and stable operation in the blast furnace, physical and chemical properties on iron ore sinter of low SiO₂ and FeO were investigated. The results obtained are summarized as follows: 1) With the decrease of FeO content in sinter under the same basicity, reduction degradation rate at 550℃ and reduction rate at 900℃ were improved. 2) The more quantity of skeletal hematite shows the worse effect on degradation of sinter under the reduction atmosphere at 550℃. 3) With the decrease of SiO₂ content in sinter under constant basicity and FeO, reduction rate at 900℃ and shatter strength are improved, while reduction degradation rate at 550℃ are not improved.

楊澈基 嶺南大學校 工業技術硏究所 1980 연구보고 Vol.8 No.1

The chemical compositions of calcium-ferrites in plant sinters have been investigated using Electron Microprobe X-Ray Analysis (EPMA). Except for the small amount of MgO and TiO, calcium-ferrite solid solution have following formula, 10CaO·XAl₂O₃·YSiO2·ZFe₂O₃where (X+Y+Z) is between 22.5 and 26.9. The chemical formula of these calcium-ferrites in plant sinters is very similar to that of synthesized quaternary calcium-ferrite solid solution. Microhardness of the calcium-ferrites in plant sinters also shows a very similar to that of the synthesized quaternary calcium-ferrites, and there is a tendency that the more Al₂O₃is contained in the calcium-ferrite, the greater is the Vicker's microhardness number of the calcium-ferrite.

This study aimed to design hair pieces and ornaments which symbolize good luck using Yeonhwamun (lotus pattern) from Buddhist Bomun (traditional motif), Bomun, Wajammun, Jeonbumun, Bounmun, Bojumun and Manjamun from Jap-bomun (eight treasures) among traditional Bomun patterns and create diverse updos for short hair for a party or wedding. It also attempted to develop hairpieces and ornaments by examining their feasibility as cosmetology products through image factor analysis. First, this paper intended to express outward beauty and auspicious meaning of the patterns by using hairpieces symbolizing Obangsaek (the color scheme of the five traditional Korean colors) from traditional Bomun in creating updos for short hair. Second, traditional Bomun-patterned hairpieces and ornaments were used in creating updos for short hair for special events such as a party and wedding. It was possible to create diverse hairstyles depending on hair length, using updos’ design techniques, C-curl and S-save. Third, according to a sensory test on updos for short hair using hairpieces and ornaments, the first factor was design, and the second factor was practicality. Analysis of hairpiece and ornament images by age has found that ‘50-60s’ revealed higher scores than ‘30-40s’ in both Yeonhwamun and Jap-bomun. In addition, satisfaction was higher when updos were created by attaching hairpieces and ornaments.

The traditional bomun symbol doesn't have only an aesthetic meaning but also a meaning of lucky. By adding the meaning of Korean traditional color, obangsaek, to use the meaning of lucky and grafting hair up style which can be displayed in variety of weddings, awards ceremonies and hair shows, to develop creative hair-up style that attracts hair artists and customers's attention, we develop a new design which can be useful in a salon. In this study, a total of nine pieces of the traditional bomun symbols including a piece of Buddhist bomun, a piece of Taoist bomun and seven pieces of Japbo bomun are applied and manufactured. There are Cintamani, Bounmun, Ruyi, Bo, Wajam, Jeon and Swastika symbols for Japbo bomun, a lotus flower symbol for Buddhist bomun and Seonja symbol for Taoist bomun symbol. This researcher uses it to design as creative up style by using the symbolism, obangsaek and plate of the traditional bomun symbol. For the hair up style design, there were traditional hair colors such as purple, light purple, pink, black, blue, green, orange and yellow the hair expresses bomun symbol by using bang, loop and braid tying up in front and on the T.P, G.P, B.P and N.P.

Cordierite 合成에 관한 硏究(I)

楊澈基,金圭鎬 嶺南大學校 工業技術硏究所 1982 연구보고 Vol.10 No.1

In order to obtain the superior refractory mineral having lower thermal expansion, cordierite was synthesized from pure reagents Al₂O₃,MgO, SiO₂. Mixtures were fired between 1,270℃ and 1,320℃ and qualitative determenation of cordierite formation was investigated X-ray diffraction analysis and polarization microscope. For the effects of impurities on the synthesis of cordierite, adding 1.5wt% Fe₂O₃and 0.5wt% K₂O₃, Na₂O to the cordierite formation. Adding 0.5wt% CaO does harmful upon the thermal expansion. In the variation of cordierite composition, Al₂O₃rich bodies approaching the theoretical composition of cordierite is superior to SiO₂MgO rich bodies on the low thermal expansion property. The bodies resintered three times are superior to bodies sintered on the low thermal expansion property.

A traditional bomun (treasure motif) pattern has the meaning of ‘good omen’ as well as aesthetic beauty. Based on the meaning of this good omen, hair jewelry and accessories were developed using traditional patterns that can be applied to hairstyles at various events such as weddings and hair shows. Then, the designs that could be made available in hair salons were developed. In this study, a total 17 different bomuns including Japbo Bomun, Buddhist Bomun, and Taoist Bomun were used to develop fascinating hair jewelry and accessories. First, Japbo patterns include Ruyi, Bounmun, Bo, Wajam, Jeon, and Manja pattern. In Buddhist Bomun and Taoist Bomun, there are lotus and Seonja, patterns, respectively. In this study, hair jewelry and accessories were developed based on the symbolism of traditional bomun patterns. In terms of detail design, ‘S’ wave and ‘C’ curl were created using eco-friendly glue ‘polyvinyl acetate emulsion,’ Woodlok adhesive, alcohol, pearls, beads, and pins. With a hardening time of about two hours, a design that goes with the pattern was developed using beads and pearls. This study attempted to develop traditional bomun-based hair jewelry and accessories using elegant oriental lines. Using the traditional bomun-based hair jewelry and accessories, this study aimed to develop creative hairstyles. In addition, there was an attempt to use common jewelry and accessories in the creation of ‘good omen’-themed hairstyles. After all, this study targeted the development of diverse creative hairstyles and to make hair jewelry and accessories that can meet hairdressers’ needs.

아동의 스트레스수준과 상담자의 상담양식이 상담성과에 미치는 영향에 관한 모의연구

강진령(姜鎭靈),양철기(梁哲基) 한국교육학회 1997 敎育學硏究 Vol.35 No.1

오늘 아동들은 갖가지 스트레스 상황에 처해 있으면서도 적절한 심리적 조력을 받지 못하고 있다. 따라서 본 연구는 학교장면에서 아동의 스트레스수준에 따른 상담자의 상담양식이 상담성과에 미치는 영향을 알아보고자 하였다. 총 260명의 6학년 아동을 대상으로 지시적 상담사례와 비지시적 상담사례가 녹음된 모의상담사례 테이프를 듣게 한 후 결과를 평가하였다. 연구결과 전체적으로 지시적인 상담방법에 다 만족스러워 했으며, 스트레스를 많이 받는 아동이 더 만족스러워 했다. 그러나 스트레스를 많이 받는 아동인 경우 비지시적인 상담방법을 스트레스를 적게 받는 아동인 경우 지시적 상담에 더 만족스러워 했다. 본 연구는 특정학생을 대상으로 모의연구인 만큼 전체아동에게 일반화시키기에는 다소 무리가 있겠으나, 아동을 상담할 경우 상담자는 아동의 스트레스수준을 고려하여 그에 적절한 상담양식을 사용한다면 더 좋은 상담결과를 거둘 수 있음을 시사하고 있다.
