This study is aimed at investigating the changes in core temperature and skin temperature of human body affected by moderate intensity aerobic exercise training. Subjects were 20 male university students to trace the change in skin temperature and rectal temperature when they undergo exercises 30 minutes a day, five days a week for 12 weeks at anaerobic threshold. In order to process the collected data, the mean and standard deviation values were calculated from the results of each item measured for two groups. One way repeated measure ANOVA was applied to find out the change with the lapse of time, while Student's t-test was used to ascertain the average difference between the two groups and Newman-Keuls test as the post-hoc. The significance level was set at 5%. The followings are the conclusion of the study conducted to examine the effects of long-term moderate intensity aerobic exercise on skin temperature and rectal temperature; First, the local skin temperature decreases generally on all body parts except on feet in the non-exercise group, whereas, it maintains the usual state on all except on hands, thighs and feet in the exercise group. Second, the non-exercise group shows decrease in skin temperature lower than average of normal state during the time from the start of excercise to recovery, while the mean skin temperature of exercise group increases generally compared to normal state. Summed up, the long-term moderate intensity aerobic exercise is believed to activate the sweat-secreting mechanism of human body and to induce to push up the skin temperature by means of rising heart rate thanks to the improved blood circulatory function, local blood flow gain and improved thermo-regulatory vascular expansion function. It comes, therefore, true that the moderate intensity aerobic exercise might affect the skin temperatures and that the moderate intensity aerobic exercise is directly connected with the thermo-regulatory function of our body.

주수현,이동철 한국중소기업학회 2003 中小企業硏究 Vol.25 No.1

본 고에서는 소기업의 국민경제적 역할과 중요성 그리고 지역경제에서 차지하는 비중은 부산을 중심으로 살펴보았다 츠뭡로그비용함수를 설정하여 추정한 결과 규모의 경제가 존재하였다. 알렌편대체탄력성은 1보다 낮아 비탄력적이었으며 소기업이 대기업보다 탄력성이 높아 요소간의 대응이 더 신속한 것으로 나타났다 한편 가격탄력성의 경우도 비탄력적이었으며 소기업이 대기업보다 민감하게 반응하는 것으로 나타났다. 싫증분석의 결과 요소간 상호관계와 가격에 대한 요소간 대체정도가 기업규모별로 상이하게 나타나 기업규모에 따라 차별적인 정책이 필요함을 보여 주었다. The economic roles and importance of small businesses in a nation, and proportional importance of the regional economy were examined in this paper, specially focused on Busan area, The effects of economies of scale in all sized companies were also appeared as a result of the inference based on the translog cost function in this paper. The Allen's Partial Elasticities of Substitution, less than 1, was inelastic, And adaptations among factors of small businesses were more fast than those of big companies by the higher coefficient of the Allen's Partial Elasticities of Substitution. The Price elasticities of factor demand was also inelastic, and small businesses were more sensitively responsible to the substitution among production factors than that of big companies As the results of substantial analyses, the difference of relatedness in production factors and the level of substitutions among factors at the price were differently appeared by the size of company. Therefore it is suggested that administrative policies were executed differently according to the company's size.

편타손상(Whiplash Injury) 환자에게 적용된 재활마사지 프로그램의 유용성

주동엽,김수근,정동혁 한국스포츠리서치 2004 한국 스포츠 리서치 Vol.15 No.2

Whiplash describes the manner in which a head is moved suddenly to produce a sprain in the neck and typically occurs after rear-end automobile collisions. It is one of the most common mechanisms of injury to the cervical spine. Although considered by some to be a form of compensation neurosis, evidence suggests that whiplash injuries are real and that they are a potential cause of significant impairment. Symptoms of cervical whiplash injury include neck pain and stiffness, interscapular pain, arm pain and/or occipital headache, and many whiplash patients have persistent complaints. The purpose of this study is to find out the effectiveness of the rehabilitation massage program applied to the patients with whiplash injury by measuring, assessing and analyzing the changes in intensity and unpleasantness of muscle pains before and after program. Surveyed from January 2003 to December 2003 were 92 patients suffering from whiplash injury. In the rehabilitation massage program, such methods as effleurage, petrissage and deep transverse friction were selected as traditional massage treatments frequently used for muscles with pain and stiffness. After 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 17 to 64 in age, with highest numbers of 29 (31.52%) registered in the twenties and next ones of 26(28.26%) in the thirties. 2. There was significant decrease in the numerical values of MPQWL, VRS and VAS after rehabilitation massage program(p<.05). 3. There was significant decrease in the intensity of pain and unpleasantness of pain after rehabilitation massage program{p<.Q5). 4. From the analysis into chronological changes in the intensity and unpleasantness of pains before and after rehabilitation 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 rehabilitation massage program is an effective treatment to rid the patients with whiplash injury of pains safely and promptly.

The purpose of our study was to evaluate whether the combined use of serum tumor markers, CA 15-3 and TAG 72 could improve the efficacy for discriminating malignant from benign ovarian masses in patients with elevated serum CA 125 levels. Serum CA 15-3 and TAG 72 were preoperatively measured by immunoradiometric assay in 78 patients with pelvic masses who had elevated serum CA 125 levels above 35 U/ml. In 32 patients with epithelial ovarian cancers, serum CA 125 levels were elevated above 65 U/ml in 97% and serum CA 15-3(>30U/ml) and TAG 72(>10 u/ml) levels were elevated in 59% and 50%, respectively, suggesting relatively low sensitivity of CA 15-3 and TAG 72. However, in 41 patients with benign ovarian tumors, elevations of these two markers were detected only in 7% and 5%, respectively, and particularly, both markers were not elevated among all the aptients over 50 years of age. Coordinate elevations of CA 125(>35U/ml) and CA 15-3(>30U/ml) or TAG 72(>10 U/ml) could discriminate epithelial ovarian cancers from benign masses with a sensitivity of 72% and specificity of 90%. Among patients over 50 years of age, sensitivity and specificity were increased to 79% and 100%, respectively. It is concluded that the combined use of CA 15-3 and TAG 72 with CA 125 could obtain an improved efficacy for discrimination of epithelial ovarian cancer, especially among patients over 50 years of age.

The completely mixing activated sludge process is generally recognized as the most effective option for a secondary treatment of wastewater. Growth dynamics of the activated sludge are sensitive to substrate availability and composition. This study was conducted to evaluate the biological treatability of the wastewaters generated from the production of poly styrene and expanded poly styrene by the CMAS process. The following results are obtained: 1) From the view of the effluent criteria of industrial wastewater for the environment, pH, BOD5,CODcr, and CODMn were considered to be the main pollutants. The values of those items were 4.50, 660㎎/ℓ, 1204㎎/ℓ and 180㎎/ℓ, respectively. 2) Even though the BODult/CODcr ratio of the composited wastewater appeared to be 0.8, the rate of biodegradation was more or less slow due to the low k value, 0.46/day. 3) Organic removal efficiencies were 86, 90, 92 and 93% at the HRT of 0.58, 0.87, 1.25 and 1.74, respectively.
