논산 대건고등학교 전례(典禮)공간의 음향성능 실태 분석

카톨릭학교는 카톨릭 정신을 기반으로 고등 교육과정이 이루어지고 있는 학교이다. 그러나 대부분의 카톨릭학교는 전례(Liturgy)공간이 따로 마련되어 있지 않고 강당과 같은 다목적 공간에서 미사가 이루어지고 있다. 뿐만 아니라 이러한 전례공간은 시설이 매우 노후화되어 있고 미사 등 종교 활동에 적합한 음향특성이 고려되지 않아 많은 음향적 결함에 노출되어 있다. 이러한 관점에서 본 연구는 논산 대건고등학교 전례공간인 마리아홀을 대상으로 음향성능의 실태를 분석하였다. 이러한 자료는 향후 이와 유사한 카톨릭학교 전례공간의 설계 및 시공 시 음향성능 확보를 위해 중요한 자료로 활용될 수 있을 것으로 사료된다.

Encapsulant curing in terms of convection oven leads to thermal induced stress due to nonuniform thermal conductivity in LED package. We have adopted infrared (IR) light for silicone curing in order to release the stress. The light uniformity irradiated on an encapsulant surface is confirmed to be uniform by optical simulation. Shear strength of die paste using IR compared to convection oven is increased 19.2% at the same curing time, which indicates curing time can be shortened. The indentation depth difference between center and edge of silicone encapsulant in terms of convection oven and IR are 14.8% and 3.4%, respectively. Curing by IR also shows 2.3% better radiant flux persistency rate of LED at $85^{\circ}C$ after 1,000 h reliability test compared to convection curing.

The purpose of this study is to investigate and analyze the learning styles for adult college students in order to better understand the factors that shape the language learning process. I examined the perceptual learning styles of 119 college students, one at ChongUp Technical College, and the second at a university located in ChonBuk Province. The subjects’ English proficiency levels varied as under TOEIC 220 score (55.5%), 220 - 470(39.5%), over 470(5.0%). Research findings are as follows: First, subjects mainly preferred auditory(38.3%) and kinesthetic (36.2%) learning style. It might be influenced by traditional teaching method used by most Korean teachers. Second, on the survey of sociological learning styles, subjects favored group - oriented style. They value group interaction and class work with two or three classmates. Third, Lower level students (under 220 TOEIC) preferred kinesthetic style than higher level. It is different from Rossi-Le’s position(1995) that more language-proficient students preferred learning through interactive methods and direct experiences with the language. However it might be different by cultural backgrounds, subjects, and research focus.

This study empirically examines the effects of the 'Thought Structure Conversion Method(TSCM)'for teaching writing and grammar to academically underprepared college students. The TSCM is an English teaching and learning method to convert the learners' thought structure from the original Korean word order to the English word order. It is one of the two core operational systems which construct the 'Five Dimensional English Learning Method' with the Vocal Structure Conversion Method(VSCM). Tests through 'Test and Retest Method'and questionnaires were administered to fifty subjects to analyze the effects of TSCM. The subjects participating in this experimental study for 15 weeks showed statistically significant improvement of their writing ability. The findings of this study confirm the value of using this method for teaching writing and grammar to college students of low-level English.
