The purpose of the present study was to investigate the relationship between isokinetic muscle function and muscle cross-sectional area (CSA). Twelve women participated in the present study, divided young (n=6, 23.7±1.9 year) and elderly women (n=6, 60.3±6.8 year). Isokinetic strength (power, strength, endurance) and CSA (psoas major and thigh muscles) measured with dynamometer and computerized tomograph, respectively. Cross-sectional area of psoas major muscle in elderly group revealed markedly smaller than in young group, but thigh muscle was not the case. Muscle CSA in young women correlated between power and endurance and psoas major muscle, as well as between muscle strength and CSA of thigh muscle. But no correlation occurred between strength and cross sectional area, except endurance which was highly correlated between CSA and endurance. In conclusion, aging decreases muscle function and CSA. Partially muscle strength correlated with muscle CSA in young women, but no correlation occurred in elderly women. Further study needed to elucidate the exact mechanism related to aging muscle with muscle density and neuromuscular function.

Structures, Nanomechanics, and Disintegration of Single-Wall GaN Nanotubes: Atomistic Simulations

Jeong Won Kang,황호정,Jun-Ha Lee,Ki OH Song,Ki Ryang Byun,Oh-Keun Kwon,Won Young Choi 한국물리학회 2003 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.43 No.I

We have investigated the structural, mechanical, and thermal properties of single-walled GaN nanotubes by using atomistic simulations and a Tersoff-type potential. The Tersoff potential for GaN eectively describes the properties of GaN nanotubes. The nanomechanics of GaN nanotubes under tensile and compressive loadings have also been investigated, and Young's modulus has been calculated. The caloric curves of single-walled GaN nanotubes can be divided into three regions corresponding to nanotubes, the disintegrating range, and vapor. Since the stability or the stiness of a tube decreases with increasing curving sheet-to-tube strain energy, the disintegration temperatures of GaN nanotubes are closely related to the curving sheet-to-tube strain energy.

In this paper. the Γ type eqivalent circuit is used to analyze the steady state characteristics of induction motor driven by inverter source. The base tests for equivalent circuit parameters of induction motor are a no-load test by rated frequency (60Hz) and a blocked rotor test by 25% of rated frequency (15Hz) which are perfomed with inverter source. and measurement of the de resistance of the stator winding. To determine more accurate parameters, four simultaneous equations obtained from equivalent circuit of the no-load test and blocked rotor test are solved by using initial values which are evaluated from simplifed equivalent circuits. The induction motor performances are computed by using these parameters and compared with measured values of the tested motor. Then it is found that the compared results show good agreement between them.

김영빈,박병근,정동혁 圓光大學校 附設 體力科學硏究所 2004 體力科學硏究 Vol.27 No.-

According to the classification criteria proposed by the American College of Rheumatology, fibromyalgia is a long-standing multifocal pain condition combined with generalised allodynia/hyperalgesia. It is the generalised allodynia/hyperalgesia that distinguishes fibromyalgia from other conditions with chronic musculoskeletal pain. Central sensitisation of nociceptive neurons in the dorsal horn due to activation of N-methyl-D-aspartic acid receptors and disinhibition of pain due to deficient function of the descending inhibitory system are probable pathogenic factors for allodynia/hyperalgesia. Furthermore, chronic pain is a chronic emotional and physical stressor. Chronic stress and chronic sleep disturbance are not specific for fibromyalgia but could be the causes of symptoms like fatigue, cognitive difficulties and other stress-related symptoms. They may also cause neuroendocrinological and immunological aberrations. The purpose of this study is to find out the effects of pain rating scale in the therapeutic massage program applied to the patients with Fibromyalgia Syndrome by measuring, assessing and analyzing the changes in intensity and unpleasantness of muscle pains before and after therapeutic massage program. Surveyed from Mar. 2003 to Feb. 2004 were 83 patients suffering from Fibromyalgia Syndrome. In the massage program, such methods as effleurage, petrissage and deep transverse friction were selected as traditional massage treatments frequently used for muscles with pain and spasm. Massage treatments were applied for 20 minutes in total before and after stretching in total program 30 minutes. After therapeutic massage program, the McGill pain questionnaire word list(MPQWL), verbal rating scale(VRS), visual analogue scale(VAS) were used to measure the degree of the pain on the patients. The major findings from this study are as follows; 1. The surveyed patients range from 19 to 62 in age, with highest numbers of 35(42.17%) registered in the thirties and next ones of 20(24.10%) in the forties. Divided by sex, 19 are men and 64 are women totalling 83 with average age of 36.5. 2. There was significant decrease in the numerical values of VAS & VRS and MPQWL after therapeutic massage program(p<.05). 3. There was significant decrease in the intensity of pains after therapeutic massage program(p<.05). 4. There was significant decrease in the unpleasantness of pains after therapeutic massage program(p<.05). 5. From the analysis into chronological changes in the intensity and unpleasantness of pains before and after therapeutic massage program with ANOVA, it became evident that the longer the period of treatment was, the higher the pains decreases drastically, while significant difference was shown in the intensity and unpleasantness of pains(p<.05). Summed up, it can be generally concluded that therapeutic massage program is an effective treatment to rid the patients with Fibromyalgia Syndrome of pains safely and promptly.

Background : Atherosclerosis is the chief underlying cause of ischemic heart disease and there is increasing evidence that inflammation is an important determinant of the development of atherosclerosis. We assessed the levels of inflammatory markers in patients with ischemic heart disease and normal group who has normal coronary angiograms. Materials and Methods : Coronary angiography was performed in 142 patients. 107 patients of ischemic heart disease(stable angina pectoris 58, unstable angina pectoris 30, Acute myocardial infarction 19) and 38 normal control subjects. We assessed the level of inflammatory markers, such as CRP, ESR, fibrinogen and leukocyte. Results : CRP, ESR and fibrinogen values of the patients with stable angina pectoris and unstable angina pectoris were higher than that of normal control group, but there were no statistical significance. Leukocyte value of the patients with unstable angina pectoris(9003.3±701.5/mm^(3)) was significantly higher than that of the patients with stable angina pectoris(6685.5±245.8/mm^(3)) and normal control subjects(6394.3±235.1/mm^(3)). CRP, ESR and fibrinogen values of the patients with acute myocardial infarction were also higher than that of normal control subjects. CRP was 3.88±2.05 mg/dL in acute mocardial infarction group, and 0.29±0.15 mg/dL in normal control subject group(p<0.05). Fibrinogen was 541.6±45.1 mg/dL in acute myocardial infarction group, 321.4±25.6 mg/dL in normal control subject group(p<0.05). Leukocyte was 10942.1±737.6/mm^(3) in acute myocardial infarction group, 6394.3±235.1/mm^(3) in normal control subject group(p<0.05). Conclusions : This study demonstrate that CRP, fibrinogen and leukocyte values of acute myocardial infarction group were significantly higher than that of control group and stable, unstable argina pectoris group. Leucokyte values were significantly elevated in unstable angina group, but CRP values were not in unstable angina group.

Berkshire를 이용하여 70일간 산삼 배양액 급여 시 육의 이화학적 특성에 미치는 영향은 다음과 같다. 산삼 배양액의 급여에 의해 육의 수분, 조단백, 조지방, 회분, pH, 가열감량, 콜레스테롤 함량, 육색, 조직감의 응집성과 검성, 포화지방산 및 불포화지방산의 비율은 차이를 보이지 않았다. 보수력, 지방색 L^(*)값, 지방산 중 linoleic acid(18:2), arachidonic acid(20:4), 필수지방산의 함량, 아미노산 중 threonine, glutamic acid, valine, isoleucine, leucine, histidine, lysine 및 총아미노산 함량은 산삼 배양액의 급여에 의해 감소하였다. 전단가, 조직감의 표면경도, 경도, 씹힘성, 지방산 중 stearic acid(18:0), oleic acid(18:1) 함량, 아미노산 중 serine, glycine, cystine, methionine, tyrosine 및 phenylalanine의 함량은 산삼 배양액의 급여에 의해 증가하였다. 본 연구결과를 종합하면 산삼 배양액의 급여는 돈육의 경도를 증가시키는 효과 외에 뚜렷한 이화학적인 차이를 나타내지 않았다. 이러한 이유는 급여된 산삼 배양액 내에 함유된 생리활성 물질의 함량이 낮고, 급여수준이 낮은 결과로 사료되어진다. A total of 60 pigs (Berkshire) were used to investigate the effect of dietary artificial culture medium of wild ginsengs (CMG) on physico-chemical characteristics of pork. About 60 kg pigs were randomly alloted into one of two experimental diet groups (C:commercial diet feed; T:commercial diet + 1 L CMG per day for 70days). Pigs were slaughtered at approximately 110 kg live weight, and chemical composition and physico-chemical characteristics were measured in pork loin. Moisture, crude protein, crude fat and ash were not significantly different by dietary artificial culture medium of wild ginsengs. Water-holding capacity was decreased by dietary artificial culture medium of wild ginsengs, while shear force was increased. However, pH, cooking loss and cholesterol contents were not significantly different between two different treatments. In color, L^(*) of fat was decreased by dietary artificial culture medium of wild ginsengs. Brittleness, hardness and chewiness were increased in dietary artificial culture medium of wild ginsengs group. In fatty acid, stearic acid (18:0) and oleic acid (18:1) were higher in dietary artificial culture medium of wild ginsengs group, whereas linoleic acid (18:2) and arachidonic acid (20:4) were higher in control group. In amino acid, serine, glycine, cystine, methionine, tyrosine and phenylalanine were higher in dietary artificial culture medium of wild ginsengs group, whereas threonine, glutamic acid, valine, isoleucine, leucine, histidine and lysine were higher in control group.
