康燦金 단국대학교 1985 論文集 Vol.19 No.-

I've reached some conclusions for variation of pulsation, reduction of the time required and the rate of retrieval in the circuit training of the National Representative skiers as the following. 1. As the result of the investigation the level of reduction of the time required of the circuit training has come out to be p<0.01 injurious to both alpine skier and cross-country skier. 2. As for alpine skier, the rate of retrieval for pulsation at ease has got faster even by 6.35% in the second trial than the first during two minutes, likewise it has improved by 4.32%in the second time of the cross-country skier. 3. The rate of recovery for pulsation of the alpine skier before motor has got faster by 7.28%, even as well as the cross-country skier shows 11.64% higher rate in the second trial than the first to turn out to be harmful level p<0.01 in the training effect.

최금찬,정창훈 한국환경과학회 2003 한국환경과학회지 Vol.12 No.12

Plasma-photocatalytic oxidation process was applied in the decomposition of Triethylamine(TEA) and Methyl ethyl ketone(MEK). Plasma reactor was made entirely of pyrex glass and consists of 24 mm inner diameter, 1,800 mm length and discharge electrode of 0.4 mm stainless steel. And initial concentrations of TEA and MEK for plasma-photocatalytic oxidation are 100 ppm. Odor gas samples were taken by gas-tight syringe from a glass sampling bulb which was located at reactor inlet and outlet, and TEA and MEK were determined by GC-FID. For plasma process, the decomposition efficiency of TEA and MEK were evaluated by varying different flowrates and decomposition efficiency of TEA and MEK increased considerably with decreasing treatment flowrates. For photocatalytic oxidation process, also the decomposition efficiency of TEA and MEK increased considerably with decreasing treatment flowrates. The decomposition efficiency of MEK was 57.80/0, 34.2%, 18.8% respectively and the decomposition efficiency of TEA was reached all 100%. This result is higher than that of plasma process only. From this study, the results indicate that plasma-photocatalytic oxidation process is ideal for treatment of TEA and MEK.

Dry and wet deposition were considered for aerosol particles. In wet deposition, aerosol particles are become nuclei to make cloud particles, the generated cloud paticles are removed by settling as rainfalls. Also, gases are absorbed in cloud particles and rainfalls in the atmosphere. In dry deposition, deposition rate is largely depends on the deposited surface areas and its properties. Some dispersion models are able to apply to obtain good results for dry and wet deposition.

Acid Rain has been investigated in Pusan Area. The range of pH indicated at 1st point to 4.05-7.2, 2nd point to 4.87-7.1, 3rd point 5.0-7.0 individually. Average pH value was decreased during small rainfall, the rainfall amount was directly related to pH in every points. Frequency ratio of pH below 5.6 in each point were resulted to 75% at 1st point, 73% at 2nd point, 42% 3rd point.

空氣拳銃 擊發時 心拍數 變化에 관한 硏究

康燦金 단국대학교 1986 論文集 Vol.20 No.-

The result of investigation into the variation of the number of heart beating. The score rate by points and the point of impact by the position at firing an air rifle for the male shooter of B high school in Seoul has come out as the following. 1. The comparison of the score rate by points. In the a group. There were three who scored more than 20% from the total points 600.In the B group, on the other hand, there was only one. The rate of high gore in an average was in the A group that has many long experienced shooter, and of low score was in the B group. 2. The comparison of the point of inpact by the position. The shooters from A group K.K. N.,L.S.S., made 20%, 25.4% in the direction of 6~7o'clock, P.K.H.l8.3% in 4~5 0'clcrk, L.J.Y.21.7% in 7~8. From the B group, on the other hand, in the same direction of 7~8, K.M.H., H.S.W., K.S.K. made the same direction with 18.6,18.3,23.3%.The reason of uneven formation of the point of impact is the work of the individualities of the shooters. 3. The variation of the number of heart-beating at firing by the score, P.K.M. from the A group had faster heart beating while he was gaining in high score, others' heart beating, on the other hand were irregular. The reason can be interpreted as the shooters were selected without consideration for the synthetic aptitude.

The effects of Laminaria japonica fucoidan extract (LJFE) on the biochemical parameters of lipid-related function were investigated in liver and serum of CCl_(4)-treated rats. LJFE of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 14 days. On the day 15, 3.3 ml/kg of CCl_(4) dissolved in olive oil (1:1) was injected 12 hours before anesthetization. We examined the lipid-related functions and enzyme activitys by measuring the levels of total cholesterol (TC), triglyceride (TG), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in serum. The results showed that CCl_(4) treatment increased the high values of TG, LDH and ALP decreased the low values of TC but LJFE pretreatment decreased the high values of TG, LDH and ALP to the low values, increased the TC. It was suggested that LJFE can be used as the potential candidate for the lipid-metabolism natural supplement.

Nowaday, Advanced technology has been applied to organic destruction technologies that are alternatives to incineration. Plasma, photolysis, and Photocatalytic oxidation processes are an emerging advanced technologies for the abatement of volatile organic compounds(VOCs) in atmospheric pressure air streams, so we has been used these technologies for destruction of VOCs. TCE, Benzene, Toluene, and Xylene were selected as objective materials. We have been studied each process and found many types of reaction parameters which effect on treatment efficiency. So combination processes, which are plasma-photocatalytic oxidation process and photolysis-photocatalytic oxidation process, have been used to increase destruction efficiency. Analysis of above materials and byproducts was carried out by GC-FID.

이 연구는 레크리에이션 활동이 발달지체아의 대인관계 및 정서적 행동에 미치는 효과를 분석하는 실험연구이다. 레크리에이션 프로그램은 놀이중심의 20개 주제로 40개 과제를 주 2회 20회 실시하였다. 연구 대상은 지적수준이 IQ 45정도인 발달지체아 20명(비교, 실험집단 각 10명씩)이고, 종속변인은 대인관계 수준과 정서적 행동(7개영역)이다. 연구결과 첫째, 레크리에이션 활동이 발달지체아의 대인관계 행동에 긍정적인 효과를 미친다. 특히, 자기중심적 요구단계인 1수준과 자기중심 우위의 동료입장 고려 2수준에 더 많은 대인관계를 향상시켜주는 것으로 밝혀졌다. 둘째, 레크리에이션 활동이 정서적 행동변화에 긍정적인 효과를 미쳐 특히, 충동성과 불안, 공격성이 감소하고, 사회화와 자아개념에 영향을 미친다. 결국, 다양한 놀이활동이 발달지체아들의 대인관계 및 정서적 행동수정에 효과적임을 미루어 보아, 특별한 교육적 요구를 지닌 발달지체 아들에게 적용할 전문적인 레크리에이션 프로그램이 적극 개발되고 이들에게 적용하여 교수적 함의의 탐색이 계속 이루어져야할 필요가 있다. The purpose of this study was to analyze the influence of applied recreation program on the interpersonal relations and emotional behavior of children with developmental disabilities so that the result of this study could be utilize as an effective information for rehabilitation and education of children with developmental disabilities. The findings of this study were as follows; First, the recreational activities had an effect on enhancing the interpersonal relations of students with mental retardation. By subareas, the experimental group made a greater progress in the levels 1 and 2, which were respectively defined as egoistic demand and putting oneself in another's place, than in the levels 0 and 3, which were respectively characterized by just rudimentary human relations and giving consideration to others. Over, the recreational activities turned out to improve their interpersonal relations. Second, the recreational activities served to develop the emotional behaviors of students with mental retardation. The experimental group became less impulsive, discouraged, anxious and aggressive than before, and their sociability and self-concept improved as well. Accordingly, the recreational activities turned out to bring a positive change to their emotional behaviors.

We get the conclusion of the ionic components of sample and the concentration of metal elements which is collected for acid composition substances using Dry Deposion, Dust Jar method at five points in Pusan. It appears higher ionic concentration from the last of February to the middle of May. It appears higher ionic concentration according to the increasing of collecting period in cation. It is higher ionic concentration according to the passing of the time at all sites in anion. The sum of cation equivalent concentration is higher than the sum of anion equivalent concentration in comparing ionic equivalent concentration. The equivalent concentration of SO₄^(2-), NO^(3-) that is gussed acid density is predominient in anion.
