The study is designed to introduce a volunteer work program in a special school setting for students without disabilities in middle schools and to investigate the effectiveness of the program. One hundred and sixty six students in middle schools participated in the volunteer work in a special school for children with mental retardation. Pretest and posttest on Disability Factor Scales and Personal and Social Responsibility Scale were administered. The test results on Disability Factor Scales and Personal and Social Responsibility Scale showed that the attitude toward students with disabilities and the interpersonal and social responsibility with others changed after extensive volunteer work with students with disabilities. Changes in interpersonal and social responsibility have shown among levels of academic achievement, while changes in attitude toward students with disabilities have not. The significant changes in the attitude and the interpersonal and social responsibility indicate that intervention program is effective for middle schooler attitudes for disabilities and interpersonal and social responsibilities. Implications for volunteer work setting in a special schools and recommendations for further study are discussed.

In order to show the effect of a vast point pollutant source on air quality of Pusan Thermoeletric Power Plant and its surrounding area, air quality around Pusan Thermoeletric Power Plant was simulated by ISCLT-2 which was supplied by EPA. For this purpose the emission amount of SO_2, NO_2 and TSP was calculated and atmospheric stability was classified for a recent decade(1985~1994) in Pusan. A result of the emission amount showed that much amount of NO_2, NO_2 and TSP are emitted from industrial area. It was clear that NO_2 is much emitted from line source and industrial area. And as a result of classification of atmospheric stability, neutral, stable and unstable state were 58%, 24.1% and 17.9%, respectivly. The result of ai quality simulation by ISCLT-2 showed that Pusan Thermoeletric Power Plant is affecting on the increse of 2.0ppb, 3.0ppb and 5.0㎍/㎥, SO_2, NO_2, and TSP respectively at its surrounding area, site A-3 which was located westward 2.2㎞ distance from Plant

The effect of MTPA was observed in 173 clonorchiasis patients who visited to the department of pharmacology, Kyungpook national university, school of medicine, from Sep., 1969 to Jun,, 1971 and 20, Mar. , 1972. In 173 patients, 162 patients had normal liver function, 10 patients were complicated with acute hepatitis and one of the patients had been inserted T tube into his common bile duct since 7 months after operation for bile stone. MTPA was administered oraly in daily dose of 7∼15㎎/㎏, which was divided into three equal part and given after each meal. To each patient the drug was given for 4 or 5 cures and one cure was composed of 6 days of drug administration and the interval between each cure was 10 days. The effect of drug was estimated with counting the number of eggs of clonorchis in the feces by the MGL method, the results were expressed as "negative", completly disappeared, and "80% diminution", number of the eggs reduced more than 80% than before treatment. Besides egg count, general symptoms and liver function before and after medication, and side effects induced by drug were also observed. The results obtained as follows. 1) In 51 patients treated with 10㎎/Kg/day for 4 or 5 cures, egg-negative rate was 49% and 80% diminution was 37%. 2) In 31 patients treated with 7 ㎎/Kg/day for first cure and than 15㎎/Kg/day for 3 or 4 cures, egg-negative rate was 58.1% and 80% diminution was 35.5%. 3) In 80 patients given in dose of 10㎎/Kg/day for first cure and then 15㎎/Kg/day for 3 cures or 15㎎/Kg/day for 4 cures, the egg-negative rate were 64.7%, and 69.5% and 80% diminution rate were 29.4%, and 23.9% respectively. 4) In the patients administered with MTPA, the gerneral symptoms and signs such as fatigue, anoraxia, indigestion etc. and hepatomegaly were improved. 5) In 10 patients complicated with acute hepatitis and administered with 3㎎/Kg/day for first cure and continued by 7㎎/Kg/day second cure and then 15㎎/Kg/day for 3 cures, 7 of them were egg-negative, 2 of them were 80% diminution. 6) Side effects induced by drug were gastric pain, abdominal pain, diarrhea, dizziness, headache, fatigue and fever, But the side effects were so mild that discontinuance of administration of drug was not necessary in most cases. 7) In the patient inserted with T tube while administered with 7㎎/Kg/day of MTPA, clonorchis sinensis flew out from the T tube in living, but with 15㎎/Kg/day, clonorchis sinensis flew out in dead. From above results we think that MTPA is a useful drug for treatment of clonorchiais, and 15㎎/Kg/day is enough to kill clonorchis sinensis in the body.

원적외선 광조사에 의한 도핑되지 않은 반절연성 GaAs의 광전류 전이와 열자극 전류

김화민,박승환,김종재,고석중,최병두 대구효성가톨릭대학교 자연과학연구소 1994 基礎科學硏究論集 Vol.1994 No.1

도핑되지 않은 반절연성 GaAs의 광전류 급냉과 열적 회복효과를 조사하기 위하여, 성장 방법이 다른 두개의 반절연성 GaAs시료에 대해 원적외선 영역(hv≤1.12eV)의 광조사에 의한 열자극 전류(TSC)스펙트럼들이 측정되었다. LEC방법에 의하여 성장된 As가 풍부한 반절연성 GaAs시료에 대한 50K에서의 광전류의 급냉 과정은 두 단계로 대별된다. 광전류 값이 최소가 되는 시간으로 전이시간 t_T를 정의할 때, (1) IR 광조사 시간 t<t_T이면, EL2(기저상태)→EL2^*(준안정상태) 전이에 의하여 광전류가 감소하고, (2)t>t_T이면, persistent photocurrent (PPC)효과에 의하여 광전류는 다시 증가하였다. 이러한 차이는 성장 방법과 조성비에 따른 잔류불순물의 농도가 광전류 변화에 영향을 준 때문으로 판단된다. 한편, 광조사 시간에 따른 TSC 피크들의 급냉과 급냉된 피크들의 열적 회복에 대한 온도 의존성은 EL2의 기저상태와 준안정 상태 간의 전이 또는 열적 회복과정과 거의 일치하였다. 따라서, 광전류의 급냉 전과 후에 각각 다른 형태로 관측되는 TSC스펙트럼 구조는 EL2 또는 EL2^*와 직접적인 관련을 갖는 트랩들의 분포에 의해 결정되고, 이 트랩들은 EL2-점결함 또는 EL2-잔류불순물로 형성된 complex에 의한 것으로 추론되었다. To study the photoquenching and thermal recovery effects in undoped semi- insulating (Sl) GaAs,the thermally stimulated current (TSCI) spectra, by illuminating infrared light (hv≤ 1.12 eV), are measured with two different Sl-GaAs samples, grown by the liquid-encapsulated Czochraski (LEC) and the horizontal bridgeman (HB) methods. In the As-riched Sl-GaAs sample by LEC method, the photo-current (I_ph) quenching process at 50 K consists of the following two stages: (1) quenching of I_ph due to the transition EL2→EL2^* before a transition time t_T and (2) enhancement of I_ph due to persistent photocurrent (PPC) after t_T, where t_T is defined as the time in which I_ph becomes minimum. However, neither re-enhancement of I_ph nor PPC are observed in the Sl-GaAs sample by HB method. This distinction results from the difference on the concentration of residual impurities, dependent on the growing method and composition rate, in the above two samples. The illumination time dependence of the quenching of TSC peaks and the temperature dependence of their thermal recovery are nearly fitted into those of the ground-to-metastable-state transition or thermal recovery process of EL2. Asa result, it is inferred that the TSC spectral structure, showing different feature before and after IR-quenching, is determined by the distribution of traps associated directly with EL2 or EL2^* and the traps are originated from a complex of EL2-point defect or EL2-residual impurities.

정영화,최성용,윤경구,용석응,김태경 강원대학교 석재복합신소재제품연구센터 1998 석재연 논문집 Vol.3 No.-

한국 대부분의 고속도로는 콘크리트로 포장되고 있으며, 플라이애쉬를 포장용 콘크리트에서 재활용하면 콘크리트의 성능을 향상시킴과 동시에 경제적 이익과 환경보호에 큰 기여를 할 것이다. 본 연구에서는 플라이애쉬를 포장 콘크리트에 재활용하고자, 플라이애쉬 치환율, 물-시멘트비, 굵은골재 최대치수를 주요실험 변수로 하여 이들이 플라이애쉬를 혼입한 포장용 콘크리트의 역학적 특성에 미치는 영향을 살피기 위해서 실험하여 통계처리 분석하였다. 이러한 분석결과를 바탕으로 포장 콘크리트의 적정배합을 제시하였으며 결과는 다음과 같다. 플라이애쉬를 혼입한 포장콘크리트의 휨강도에 영향을 미치는 인자는 플라이애쉬 치환율이 가장 큰 것으로 나타났으며, 다음으로 굵은골재 최대치수와 물-시멘트비 순으로 영향을 미친다. 또한, 플라이애쉬 치환율과 굵은골재 최대치수의 상관관계가 가장 큰 것을 알 수 있었다. 목표압축강도를 목표 휨강도의 6배로 선택하여 적정구간을 결정하였으나, 적정배합구간이 목표압축강도에 의해서 결정되었다. 이는 플라이애쉬의 작은 수화물이 공극을 효과적으로 채움으로써 휨강도의 증진에 크게 기여하기 때문으로 판단된다. 고속도로 포장에 적용할 수 있는 32mm의 굵은골재 최대치수와 45%의 물-시멘트비를 사용하는 목표 휨강도 45kg/㎠의 적정배합에서는 5.0%까지 플라이애쉬를 치환 가능하고, 50kg/㎠의 적정배합에서는 2.5%까지 치환 가능하다. 공항 포장에 적용할 수 있는 40mm의 굵은골재 최대치수와 37%의 물-시멘트비를 사용하는 목표 휨강도 45kg/㎠의 적정배합에서는 4.5%까지 플라이애쉬를 치환 가능하고, 50kg/㎠의 적정배합에서는 2.0%까지 치환 가능하다. The most of highway in Korea have been paved by concrete since last ten years. The recycling of fly ash in pavement concrete may result in economics, the improvement of concrete quality and the reservation of environment. This paper focused on the series of experiment and statistics analysis with experimental variables such as fly ash substitute ratio, water-cement ratio and maximum size of coarse aggregate in order to investigate the feasibility of recycling of fly ash in pavement concrete, to see the strength characteristics and t propose the optimum mix design based on previous results. The results of experiments and analysis were follows; The fly ash substitute ratio affected most seriously to the flexural strength of concrete among main variables, followed by maximum size of coarse aggregate and water-cement ratio. The interaction between fly ash substitute ratio and coarse aggregate size was the biggest. The optimum mix design was determined by target compressive, which was selected as 6 times of flexural strength. This indicated that the small hydrate of fly ash in concrete filled in effectively and resulted in the enhancement of flexural strength. the optimum mix design for highway pavement concrete with 32mm of maximum size of coarse aggregate and 45% of W/C can incorporate up to 5.0% and 2.5% of fly-ash at 45 kg/cm² and 50 kg/cm² of target flexural strength, respectively. The optimum mix design for airport pavement concrete with 40mm of maximum size of coarse aggregate and 37% of W/C can incorporate up to 4.5% and 2.0% of fly ash at 45 kg/cm² and 50 kg/cm² of target flexural strength, respectively.

The surgically created arteriovenous fistula has become the method of choice in achieving vascular access for maintenance hemodialysis. The authors performed 70 arteriovenous fistulas for angioaccess in 65 patients with CRF at the Department of Thoracic and Cardiovascular Surgery in Chungnam National University Hospital during the period form August 1990 to November 1991. There were 4 cases of early obstructions due to inadequate vein in 2 cases, inadequate artery in 1 case and technical failure in 1 case. In 3 cases except 1 case who was transferred to other hospital, re-AVF were tried with successful outcomes. There were 2 cases of minor complications (wound infection and arm swelling due to venous hypertension) which were managed conservatively with successful outcomes. During the mean follow up of 8 months in 59 patients whore are not expired or lost during follow up, 3 cases of late thrombosis were occured with fistula patency rate of 94.9%. The authors consider the 'anatomical snuffbox' arteriovenous fistula as a primary choice and consider another method if it is not possible.
