박정호,전기일,정창훈 한국환경과학회 2003 한국환경과학회지 Vol.12 No.12

This study was carried out to obtain the optimal ammonia removal efficiency using pyroligenous liquid for the economical and environment-friendly odor removal at a petty livestock farmhouse. The ammonia removal efficiencies were evaluated due to changing dilution rates(× 10, ×20, ×30, ×50 and ×100 times) and different spray amounts(10㎖ and 20㎖) of pyroligenous liquid. The wet scrubber device was used to remove odor in closed-type livestock farmhouse. According to dilution rate of the pyroligenous liquid, the optimum rate was 20 times and the removal efficiency increased by decreasing dilution rates. In the case of spray amounts with the optimum dilution, the amount was 20 me and the removal efficiency increased by increasing spray amount. Also, the removal efficiency by using wet deodorizing device was 83.0~97.0% with 20 times diluted liquid.

박종윤,이상균,한기평,이재욱 성균관대학교 1991 論文集 Vol.42 No.1

n-type Si water(100) 위에 Mo를 1000Å을 증착한 후 400℃에서 120분간 pre-annealing(예비 열처리)하고 기존의 FA(Furnace Annealing) 방법과 본 실험실에서 개발, 제작한 RTA(Rapid Thermal Annealing) 장치로 post-annealing하여 hexagonal MoSi_2와 tetragonal MoSi_2를 형성하였다. 이는 XRD로 phase를 확인하였으며 AES depth profile를 이용하여 Si의 확산 메카니즘을 조사하였다. 기판의 온도가 400℃인 경우 MoSi_2의 형성이 용이하고 표면의 grain의 morphology 또한 FA방법에 비해 RTA방법이 크고 균일하게 형성되고 pre-annealing한 시편이 균일한 grain을 형성함을 알았다. 이는 grain의 morphology가 확산에 커다란 영향을 미치고 있음을 암시하고 있다. Mo films with a thickness of 1000Å were prepared on n-type Si(100) substrates by electron beam evaporation and heated to form the MoSi_2 of the hexagonal-and tetragonal-phase by the FA(Furnace Annealing) and RTA(Rapid Thermal Annealing) methods. The phases of Mo-silicide were confirmed by XRD. AES depth profiles were performed to obtain the Si distribution by the diffusion. Also, the change of MoSi_2 surface morphology was analyzed by SEM and EDX to investigate the mechanism of diffusion. When the substrate temperature was 400℃, well defined MoSi_2 was formed easily, the morphology of grain was distributed largely and uniformly. And it was found that the performance of the pre-annealing before post-annealing lead to lower about 150℃ for the formation temperature of very stable MoSi_2.

朴基琥 仁川敎育大學校 科學敎育硏究所 2000 과학교육논총 Vol.12 No.-

공운동시 시표의 이동속도가 빠르고, 시시각각 변화하는 시표를 잘 보기 위해서는 동체시력이 좋아야 한다. 따라서 본 연구에서는 일반운동에 의해 동체 시력이 향상되는가?, 안구운동에 의해 동체시력이 향상되는가?, 안구운동에 의해 운동수행능력이 향상되는가? 등에 대한 문제에 대해 선행연구를 중심으로 살펴본 바 다음과 같다. 1. 일반운동에 의한 정지시력은 운동초기에는 감소되나, 그 후 직선적으로 증가하며, 운동후에는 운동전의 시력보다 향상됐다. 일반운동이 동체시력에 미치는 영향은, 운동 중에는 감소하였다가 운동 후에는 동체시력이 좋아지는 것으로 나타났다. 2. 운동선수와 비운동선수의 시기능의 차는 여러 가지 시기능 중 정지시력, 동체시력, 초점조절, 운동 반응시간, 도약운동, 주변시야, 시각 반응시간, 지각심도 등 대부분의 시기능이 운동선수가 비운동선수에 비해 우수한 것으로 나타났다. 3. 많은 학자들은 안구운동에 의해 운동수행 능력이 향상된다고 보고하였으나, 그것이 안구운동에 의한 향상인지. 측정기계에 친숙해져 향상된 것인지는 결정적인 증거를 제시하지 못하고 있는 실정이다. 그러나 운동에 의한 근육의 적.백근의 변화와, 안근의 운동단위 수가 일반근육에 비해 아주 작다는 생리적 근거와, 운동선수와 비운동선수 간의 시기능의 차가 뚜렷하게 나타나는 점등을 미루어 볼 때 안구운동에 의해 운동수행 능력이 향상될 수 있다고 생각된다. The purpose of this study is analysis to change of dynamic visual acuity through general exercise, to change of dynamic visual acuity and motor performance through eye exercise. The summary of this study are as follow: 1. Many researchers reported that static visual acuity was reduced on the first stage of general exercise and then increased. Static visual acuity after exercise was better than before exercise. Dynamic visual acuity was reduced during exercise, but dynamic visual acuity after exercise was better than before exercise. 2. Most visual functions(static & dynamic visual acuity, motor reaction time, near point convergence, visual proaction time, visual reaction time, contrast sensitivity facility) of athlete were better than nonathletes. 3. Many researchers reported that motor performance was increased through eye exercise, but it is not scientific evidence. I think that motor performance is increase through eye exercise. That's why muscle fiber type(ST & FT) change through exercise, difference of visual functions between athletes and nonathletes be clear and eye muscle's motor unit is very small.

Passive Sampler를 이용한 진주시 NO_2 농도 분포

박정호,전기일,서정민 진주산업대학교 농업기술연구소 2000 農業技術硏究所報 Vol.13 No.-

In 1996, about 80 % of total emission in Chinju was emitted from mobile source, with about 26.9 % of nitrogen dioxide (NO_2) coming from mobile source. In this study, the distributions of NO_2 concentrations were investigated with Passive Sampler in Chinju. Passive Sampler can be a useful method to evaluate distribution of a detailed concentration in large area. The concentrations of NO_2 in downtown Chinju were appeared in the rage of 0.0046∼0.0285 ppm. And the concentrations of NO_2 in rural areas were appeared in the rage of 0.0018∼0.0176 ppm at the road side and 0.0014∼0.0064 ppm at the green zone. The mean concentration of NO_2 was appeared to be about 0.0043(±0.0020) ppm in Chinju. The NO_2 concentrations at the downtown site were about 21∼98 times higher than in rural areas.

(2)The range of sound level at school area was between 51.8 dB(A) and 70.6 dB(A). And these values were higher in outside compared with that in inside. (3)Mean sound level at business area was not showed road side and normal site variations, but was higher in the daytime compared with that in daytime.

태음인 체질의 비만아동에 대한 운동처방

박기호,정연희 仁川敎育大學校 科學敎育硏究所 2003 과학교육논총 Vol.15 No.-

본 연구는 비만해소 방안과 효과의 검토 및 자료를 제시하기 위하여, 비만도 20% 이상 초등학교 5·6학년 남학생 중 체질진단결과 태음인체질의 10명을 대상으로 10주 동안 주4회, 50∼70% HRmax의 강도로 운동처방프로그램을 실시하여 운동처방 전·후의 신장, 체중, 혈압, 심박수, 체지방량의 신체적 변화와 특수 인성검사A의 심리적 변화를 측정하였으며, 자료분석은 SPSS통계프로그램의 비모수 검정의 Wilcoxon 부호순위 검정을 이용하였다. 신체적 변화에서는 신장은 근사 유의확률이 P < .005, 혈압은 수축기와 이완기에서 P < .011과 P < .026, 체지방량은 P < .028로 유의한 것으로 나타났으나, 신장은 운동처방에 의한 영향이라고 볼 수 없으므로 유의한 차이가 없는 것이 타당하다. 체중과 심박수에서는 유의한 차이가 나타나지 않았다. 심리적 변화에서는 타당도 척도(Validity Scales), 일반 성격척도(General Personality Scales), 특수적응척도(Special Adaptation Scales)에서는 유의한 차이가 나타나지 않았다. 아동비만을 사상의학의 바탕인 체질의학에서 체질적 특징과 비만에 대한 신체적·심리적 특징을 파악하여 체질에 맞는 10주간의 짧은 기간이지만 규칙적으로 꾸준히 운동을 실시한다면 비만을 억제하거나 치료할 수 있고, 나아가 성인비만으로 이환될 가능성을 예방할 수 있을 것이라 생각된다. The purpose of this study was to investigate the effective anti-obesity measures and its effects. The research was conducted to ten boys(the 5th and 6th graders in elementary school) whose obesity degree is over 20 percent. The subjects with Taeeum-In constitution are exposed to exercise programs with 50 to 70 HRmax for 10 weeks. The exercise prescription program was implemented 4 times a week. The physical and psychological changes was measured by the pre & post-program. The analysis of data was relied on Wilcoxon Signed Ranks Test among nonparametric tests(significant level P<.05). The results of this research are as follows: 1) in respect of the physical changes, the blood pressure is significant(P<.011 and P<.026) in the contraction period and the relaxation period respectively. The amount of body fat is significant(P<.028). But heights is not significant(in spite of P<.05) because it was not influenced by the exercise prescription. Weights and heart beats are also not significant; 2) in respect of the psychological changes, the desirability of validity scales and General personality scales and special adaptation scales are not significant. This study suggests that regular exercise in accordance with human constitution may treat obesity and prevent transferability for adult obesity.
