The Taegeuk Poomse 1 through 8 of Taekwondo are based upon eight major branches of philosophical theories. The propose of this study was to investigate the nfluence of Taekwondo poomse trainning on heart rate, MVO2, energy metabolism in primary school students. Subjects for this study were eight male the fifth∼sixth grades students who participated in exercise program consist of Taekwondo poomse trainning in dojang which is located in Shinlim-2dong, Kwanak-Gu, Seoul(12.7± 0.5years, 150.8 ±4.6cm, 45.1 ± 9.4kg, 24.9 ± 9trainning length). The results of thet this study are as follows: 1) The average of heart rate was Taegeuk Poomse 1 through 8 of Taekwondo 90.57± 4.gbeats/min in rest and 139.7 ± 17.5beats/min in exercise. The minimum heart rate was 89.0±2.8, peak heart rate was 167.1 ±6.4 in exercise. It was ranged from 42% to 80% 2) of the max heart rate and ranged 42 to 65%HRmax. Taegeuk 1 Jang was differenced with others Jangs significantly(p<0.05), 2) The time of the Taegeuk 1 through 8 Jang of Taekwondo was 5minutes 12seconds. Heart rate was ranged from 90.6 ± 7.85beats/min to 171.8 ±8.Ibeats/min and increased linearly. 3) The average of the MVO2 was 11.1 ±0.78mmHg · bpm-3 in rest and 19.1 ± 1.2mmHg ㆍbpm-3 in exercise. MVO2 was ranged from 10.5mmHg · bpm-3 to 20.3mmHg · bpm-3. There were not difference between Taegeuk Poomses(p<0.05). 4) The energy metabolism was as follows: Mean VO2 Respiratory exchange ratio, energy consumption were 0.51(V02L/min),0.71(RQ),2.32Ckca1/min) in rest respectively. but In exercise Mean VO2 Respiratory exchange ratio, energy consumption were 0.89 ± 0.18( V 02L/min), 0.79±0.08(RQ), 4.26±0.51(kcal/min) respectively . The difference was only between Taegeuk 1 Jang and Taegeuk 3 Jang(p<0.05). This study showed that the Taekwondo Poomse trainning was proper exercise for fitness, body composition and weight control in normal, abnormal(obese) children because the Taekwondo trainning are dynamic and exciting sport.

Natural convection from a horizontal annulus with spacers has been studied on the effects of Rayleigh numbers and position of spacers by experimental method. In case of vertical spacers, the maximum local Nusselt number appears at θ=150° in a conducting tube and θ=30° in a cylinder. The local spacer Nusselt numbers show positive values on the lower spacer, but negative values on the upper spacer. In case of horizontal spacers, the flow over the spacer is more active than that of under the spacer as the Rayleigh number increase. The maximum local Nusselt number appears at θ=180° In a tube and at θ=0° in a cylinder. The local spacer Nusselt number show positive values on the upward surface of spacer, but negative values on the downward surface of spacer. The mean tube Nusselt numbers and mean cylinder Nusselt numbers with vertical spacer are increased 11% And 2.7%, respectively by those of horizontal spacer.

This is the report for 1971 of the third year project among the three years plan on the development of sheep range in Mt. Chiri. To investigate the effect of native grasses in Mt. Chiri on the breeding percentage of sheep this experiment was carried out from March 22, 1971 to March 21, 1972. Numbers of experimental animal used in this experiment were 12. Furthermore, the processing method of wool, marketing, economical analysis in the collective feeding and storage were investigated in cooperation with this experiment. The results obtained here were as follows; 1. For the processing method of wool, there are two ways; one of the processing method of wool is the self-processing method which follows the easy method of wool processing and another of the processing method of wool exchange with the good of wool texture company which follows the charge processing method of wool. 2. For the marketing route of wool, because the wool texture company can buy limitlessly wool, there are two ways to sell wool. The one of the way is the direct sell method of wool to the wool texture company and the other of the way is the sell method of wool via the route of circulation mechanism. 3. In the case of economical analysis for the collective feeding of sheep, if farms could raise 3,000 of sheep in the method of collective feeding it could get net income of 150,000 to 300,000 won for 52 days per farm per year. 4. For the storage of wool, to attach of wool fat must be needed and in the case of short period storage, wool must be placed in the arid place and in the case of long period storage, wool should be prevented from the attack of insect and rat, attachment of spurious article such as dust, decrease of weight and denaturation of wool fat. 5. The breeding percentage of sheep fed only native herbages plant was 60%.

지리산 면양목장 조성에 관한 연구 : Ⅰ보. 면양목장 조성 및 면양사육 단지화 조성을 위한 기초조사 Ⅰ. Fundamental Survey of Resources for the Development of Sheep Range and Sheep Farm Grouping

정현승,강봉태 진주산업대학교 1970 論文集 Vol.4 No.-

This survey reports the availability of the various resources such as geography, meteology, traffic condition, soil property, labor resource, pasture distribution and water resource, for the development of sheep range and sheep-farm group, on the first step to the three-year plan in an area around the Forestry Experiment Station of Chinju Agricultural and Forestry Junior Teachnical College in Mt. Chiri. 1. The geographical conditions of the region found to be fit for the establishment of sheep range were as follows; longitude:127˚44'east,latitude:35˚22'north,elevation:600-900m above marine surface level, slope:5-25˚, total area: 280 ha, and administrative district: from high level flats to Yeo-gok and Dusuk village, Yupyung-ri, Samjang-myun, Sanchungkun, Kyung Sang Nam Do, Korea. Especially, eighty seven farm households and Karangip primary school distriduted around this region were found to be the reasonable resources for the development of sheep farm group in this region. 2. The soil of the area was composed of most of sand-loam with PH 5.3∼5.8, 2-5% of grit and 13.3% of humus (4.6-19.3%) among 30∼50㎝ depth of surface soil. These fertile soil properties were found to be fit for the development of pasture. 3. The meteological records of this region were found as follows: frosty period: from October 16 to April 22, yearly mean air temperature: 9.2℃ , ranging from 26.6℃ in August to (-)12 in January, annual rainfall: 2,346mm, yearly mean wind velocity: 6.2m/sec, direction of the wind: north-west in winter and south-east in summer. According to the above results from only one-year observation, the meteological conditions of this region were similar to those of Dae-Kwan Ryung area and were estimated to be favorable for sheep raising. 4. In this region 35 species of wild grasses were prosperous. The green yield of the grasses averaged 1,584㎏ per 10a and 0.87a was required for grazing a sheep. Therefore, it was estimated that about 3,000 heads of sheep would be well raised in this region. The fact that about 30 percent of Mt. Chiri area is available for sheep pasture suggested that 400,000㎏ of wool, or 250,000,000 won in price(equivalent to 1/10 of the total wool imported in 1967)could be gained from grazing about 100,000 heads of sheep in the whole area of Mt. Chiri, 54,000 ha. 5. Sufficient water resources, conclusive of mooring by the farmers around this region, irrigation water, underground water and especially the pond situated in high level flats were found to be available and the quality of water was satisfactory for watering sheep. 6. Concerning the traffic situation of this region, the construction of 1.5㎞ of road to Dusuk village (with 200m of bridge) and three 2㎞ range path from Dusuk village were required. However, such traffic problems are not serious because the sheep farming requires the road only for disposal of wool produced once a year. 7. From the managment survey for 87 farms around this area, it was found that each farm had 1,019.6 hours of unemployed labour per year, which was sufficient for raising 60 heads of sheep. So it could be estimated. that potential labour enough for raising 5,200 heads of sheep was reserved in this area. Moreover, the Karangip primary school boys are available as a good resource of labour for sheep grazing. The great deal of by-products of sericulture and potato-farming, which were the major industries in this region, was available for sheep raising.

콘택트렌즈 보존 용기 유래 가시아메바 KA/L5주의 세포질 내에 존재하는 bacterial endosymbiont(내공생세균)를 투과전자현미경으로 관찰하여 확인하였다. 숙주인 가시아메바 KA/L5주는 형태학적으로 제2군에 속하였고, rDNA PCR-RFLP 결과 A. lugdunensis로 동정되었다. 미토콘드리아 DNA RFLP와 동위효소 분석상 이 충주는 국내 콘택트렌즈 보존용기에서 가장흔히 분리되는 type인 KA/Ll주, 국내 임상 분리주 중 하나인 KA/E2주, 내공생세균을 가지는 것으로 보고된 병원 냉각수 유래 KA/W4주 및 L3a주와 동일하거나 매우 유사한 성적을 보였다. 내공생세균은 약 1.38× 0.507㎛의 크기였고, 아메바 세포질 내에 불규칙하게 분포하고 있었으며. 그 표면에 아메바의 ribosome이 부착되어 있었다. 내공생세균을 둘러싼 lacunae나 막과 같은 구조는 관찰되지 않았다. Legionella 특이 primer를 이용한 효소중합반응(PCR)에서 내공생세균의 염색체 DNA는 증폭되지 않았다. A. lugdunensis의 우리말 이름을 담수가시아메바로 제안한다. Transmission electron microscopy of an Acanthamieba isolate (KA/L5) from a contact lens case revealed bacterial endosymbionts within cytoplasm of the amoebae, The Acanthamoeba isolate belonged to the morphological group II. Based on the polymerase chain reaction (PCR) - restriction fragment length Polymorphism (RFLP) of 18S ribosomal RNA coding DNA (rDNA), the Isolate was identified as A. lugdunensis. Strain typing by isoenzyme analysis using isoelectric focusing (IEF) and mitochondrial (Mt) DNA RFLP revealed that the isolate was closely related with KA/Ll , the most predominant type of isolates from contact lens storage cases, KA/E2, a clinical isolate, KA/W4, preciously reported to host endosymbionts, and L3a strains of A. lugdunensis. The endosymbionts were similar to those of KA/W4 In aspects that they were randomly distributed in both trophozoites and cysts, and were rod-shaped bacteria measuring approximately 1.38x 0.50㎛. But the number of endosymbionts per amoeba was significantly lower than that of KA/W4. They were neither limited by phagosomal membranes nor included In lacunae- like structure.

Objectives : Recent studies have shown that schizophrenic patients are at increased risk to commit acts of aggression, and aggressive behaviors have severe critical results for the patients and victims. The purpose of the present study is to assess the homicidal behaviors of schizophrenic patients as a extreme case of aggressiveness. Methods : 93 homicidal schizophrenic patients and 93 non-homicidal schizophrenic patients participated in this study. Diagnostic evaluation was made with SCID (Structured Clinical Interview for DSM-IV), and personality trait was evaluated with SIDP (Structured Interview for DSM-IV Personality Disorders). Symptom evaluation was done with PANSS (Positive And Negative Syndrome Scale), and violent behaviors were assessed with LHA (Life History of Aggression) and OAS (Overt Aggression Scale). Results : There were no significant differences in demographic vahables, schizotypal personality trait and antisocial Personality trait between two groups. Mean age at homicidal commitment was 34±8.9 years and 9.8±7.5 years after the onset of illness. The major criminal victims were the parents of the patients (N=49, 53.7%). The aggressiveness was higher in homicidal schizophrenic patients in LHA and OAS scales. There were statistical significances in separate items of the PANSS scale such as excitement (P4), Poor rapport (N3), lack of judgement and insight (G12), disturbance of volition (G13), Poor impulse control (G14) and active social avoidnance (G16), but not in the positive, negative, general subscales and the total scores of the PANSS scale. Conclusion : Excitement and poor impulse control persisted in homicidal schizophrenics, although overt psychotic Symptoms decline after proper treatment. Homicidal behavior can be preventive if proper treatment for excitement and poor impulse control are given.

^(155,156)Gd 동의원소의 keV 영역 중성자 포획단면적 측정

정원정,황정훈,김현,노태익 東亞大學校 2004 東亞論叢 Vol.41 No.-

The Neutron Capture Cross-Section of ^(155,156)Gd were measured in a neutron energy region from 15 to 85 keV using the 3MV Pelletron accelerator of Tokyo Institute of Technology. Pulsed neutrons were produced from the ^(7Li)(p,n)^(7)Be reaction. The incident neutron spectrum on a capture sample was measured by means of a TOF method with a ^(6)Li-glass detector. The capture γ-ray were detected with a large anti-Compton NaI(TI) spectrometer. A pulse-height weighting technique was applied to measured capture γ-ray pulse-height spectra to derive capture yields. The capture cross sections were obtained by using the standard capture cross-section of ^(197)Au. The present results are corrected for isotope impurities of sample because the samples contain various isotope Godolinium. The present results are compared with the previous measurements and the evaluated data of ENDF/B-VI.
