양광규,송치현,김찬호,Yang, Gwang-Gyu,Song, Chi-Hyeon,Kim, Chan-Ho 한국연초학회 1980 한국연초학회지 Vol.2 No.1

Zeolite의 일종인 clinoptilolite를 담배필터 첨가제로 활용하는 연구를 하였다. 입자크기 30 $\pm$ 5 A.S.T.M. mesh의 clinoptilolite와 charcoal 1 : 1 (V/V)로 혼합하여 삼중필터의 cavity부분에 충진했을 때, 1. Cellulose acetate필터에 비하여 nicotine 35%, T.P..M.22%를 감소시켰으며, 2. Gas phase중 n-amyl alcohol등 aliphatic compound와 furan등 cyclic compound를 cellulose acetate filter에 비하여 60$\pm$ 5%를 감소시켰다. 3. Charcoal의 removal efficiency는 40-50% clinoptilolite의 10-20%에 비하여 큰 값이였지만 charcoal은 분자량이 큰 aromatic compound의 removal efficiency가 50$\pm$5%로서 aliphatic compound의 removal efficiency 40: 5%보다 큰 값이였음에 비하여 clinoptilolite는 alcohol과 ketone계열의 분자갹이 작은 화합물의 removal efficiency가 15-20%로 cyclic compounds의 removal efficiency 10-15%에 비하여 보다 큰 값이었다. 이 두물질의 gas phase성분의 흡착기능은 상호 보완적임을 알 수 있었다. The cavity of triple filter was filled with the mixture of clinoptilolite and charcoal(1:1, V/V). The particle size of clinoptilolite was 30$\pm$5 A.S.T.M mesh. The reduction effects of the important gaseous components by this mixture were obtained as follows: 1) In comparison with the normal cellulose acetate niter, the contents of nicotine and T.P.M. were reduced about 35% and 22% respectively. 2) Many aliphatic and cyclic compounds were also substantially reduced in an average of 60%. 3) In contrast with the charcoal, the removal efficiency of clinoptilolite was revealed as higher (15-20%) in case of aliphatic compounds than the one (10-15%) of cyclic compounds. The above results showed us that the removal function of gaseous components was quite complementary each other (charcoal and clinoptilolite).

Clinoptilolite의 Menthol보유성에 관한 연구

양광규,조성희 한국연초학회 1984 한국연초학회지 Vol.6 No.2

In this study, clinoptilolites were subjected to an array of experimental conditions, such as variations in heating temperature, reaction time, and molarity of acid and bass, and their responses measured. The activation levels were measured by adsorption indexes of toluene and ethyl alcohol and the X-ray spectra of clinoptilolites treated with acid and base. The effect of clinoptilolites on the menthol fuation was estimated by the amount of menthol produced after a given time of storage. The results were as follows: The optimum conditions for the clinoptilolites treatment were found to be IM HCI, IM NaOH, IMHCl-lM NaOH, and IM NaOH-lM HCl at $100^{\circ}C$ for 2 hours. 2. It was noted that clinoptilolites, untreated or treated with HCl, could not be used for the menthol fixation since the catalytic crating of menthol occurred with them. 3. The results from the residual menthol measurement in clinoptilolites after a specific period of storage showed that the best menthol fixation occurred in those treated with IM NaOH. 4. The menthol fuation by cigarettes with mentholated clinoptilolites was far better than that obtained by the use of mentholated tobacco column. 5. Most components in cigrettes smoke were generally reduced by the adsorption to clinoptilolites treated with IM NaOH.

납심의 온도상승효과를 고려한 납-고무받침(LRB)의 비탄성응답 평가

양광규,송종걸 한국지진공학회 2016 한국지진공학회논문집 Vol.20 No.5

The lead-rubber bearing (LRB) dissipates seismic energy through plastic deformation of lead core. Under large-displacement cyclic motion, the temperature increases in the lead core. The shear strength of a lead–rubber bearing is reduced due to the heating effect of the lead core. In this study, the seismic responses such as displacement increasing, shear strength and vertical stiffness degradations of LRB due to the heating effect are evaluated for design basis earthquake (DBE) and beyond design basis earthquake (150% DBE, 167% DBE, 200% DBE).

운동 중 체온변화에 관한 연구

김기봉,양광규 경성대학교 1998 論文集 Vol.19 No.1

The purpose of this study was designed to examine the changes of the body temperature reaction during exercise. The measurements were made in oral, skin and rectum temperature and at three times in early morning, mid-day and evening on the bicycle ergometer in the intensity of 60% VO?? for 40 minutes each time. The subjects were selected 6 women volley ball players at B Universiy. The results of the study were as follows; 1. The temperatures of skin and rectum between early morning, mid-day and evening before exercise were different but not significant in the end of exercise. 2. The increases of the rectum temperature in accordance with differences of the body temperature before exercise were shown differently. The increasing temperature were about 1.18±0.30℃ in early morning, 0.91±0.27℃ in mid-day and 0.81±0.16℃ in evening. 3. The increases of the skin temperature in accordance with differences of the body temperature before exercise were shown differently. The increasing temperature were about 0.67‘0.14℃ in early morning, 0.50±0.19℃ in mid-day 0.41±0.18℃ in evening.

국부세굴을 고려한 교량의 지진 응답 평가

김나연,송종걸,김민기,양광규 한국방재학회 2015 한국방재학회 학술발표대회논문집 Vol.14 No.-

세계적으로 이상기후 현상으로 인해 자연재해 피해사례가 증가하고 있는 추세이며, 그 규모도 증대하고 있다. 국내의 경우 지리적인 영향으로 인해 여름철 집중호우 및 태풍의 발생이 빈번하다. 홍수시 급격히 증가한 유속으로 인해 교각 기초부의 국부세굴 발생은 교량 구조물에 심각한 손상을 일으킬 수 있다. 이러한 피해는 대부분이 중소하천 교량에서 발생하고 있다. 또한 최근 세계적으로 지진의 발생 빈도수가 증가하고 있는 추세이다. 우리나라의 경우 대륙판 내부에 위치하고 있어 지진으로부터 안전하다는 인식이 강했지만 최근 국내 지진 발생 빈도수의 증가로 더 이상 지진에 안전한 지역이 아니라고 판단할 수 있다. 지진은 발생 시기나 강도 등을 예측하기 어렵고 피해지역 또한 광범위하여 대규모의 재산 및 인명 피해를 초래할 수 있다. 따라서 본 연구에서는 홍수로 인한 교량피해의 직접적인 원인인 교각 기초부의 국부세굴과 지진하중의 복합적인 영향을 받는 교량 구조물의 지진 응답 평가를 위해 강원권 하천의 수리 및 지반 자료를 이용하여 발생 가능한 국부세굴 심도를 고려하고 PEER Strong Motion Database에서 실제지진기록을 사용하였다. 설계기준에 의거하여 설계한 모의분석용 교량 구조물에 대해 OpenSEES 프로그램을 사용하여 비선형 시간 이력 해석을 수행하였으며, 해석 결과를 이용하여 교각의 지진취약도를 분석하였다.

Some or the parameters affecting the thermal analysis of different types of ground tobacco have been discussed. The sample, Korean flue- cured and burley and Greek orient tobacco leaves were run in air at heating rate of $10^{\circ}$ and 20^{\circ}C$ per minute. The thermograms obtained were divided into four temperature zones. The effect of different heating rates on thermal degradation has been discussed At the lower heating rate the maxima of DTA curves in zone 3 and 4 were 25-$40^{\circ}C$ lower than that of the higher heating rate.
