대부분의 근대예술영역에서 시도된 자본주의적 저항운동은 예술과 기술의 융합, 즉 상징적 경계의 새로운 형성을 통해 진행되었다. 러스킨과 모리스로 대표되는 이러한 저항운동은 수공예 장인의 부활을 통한 장인적 예술의 복원이 목표였지만 결과적으로 예술의 계급화를 초래하게 되었고 자율적인 노동을 배제하게 되는 탈장인적인 예술이 되었다. 이에 본 연구는 장인적 노동의 복원을 위한 노력으로서 유일하게 기계제대공업이 가져온 조건을 적극 활용하는, 즉 '기술과 예술 그리고 기계와 산업의 융합'을 통해 상징적 경계의 해체와 새로운 융합을 시도하였던 바우하우스에 주목하여 그것의 '행위자들actors'을 중점적으로 살펴보고자 한다. 본 연구에서는 16세기 르네상스 예술부흥운동, 19세기 미술공예운동, 그리고 바우하우스의 예술적 사조가 역사적으로 연계되어 있다는 것을 전제로 <생산으로서의 장인적 예술, 예술소비로서의 민중의 권리, 표현방식으로서의 근대기술>의 교량역할을 수행했던 바우하우스 실천가들과 그들 사이의 협력과 갈등에 대한 고찰을 통해 바우하우스가 디자인 민주주의 이념을 구현하려 하였다는 점을 주장하고 있다. 더 나아가 현대 메타기술의 시대가 디자인과 기술의 융합을 통한 민주주의로의 이행을 추동하고 있어 바우하우스의 '협력과 갈등'그리고 '위기와 해체'로부터 반면교사해야 함을 보여주고 있다.

We studied the effects of soy isoflavones supplementation with exercise on bone mineral density and the urinary excretion of deoxypyridinoline as an index of bone resorption rates in postmenopausal women. A total of 67 postmen-opausal women were assigned to Isoflavone (90 mg/day) or placebo groups. These group were further divided into groups that undergone a regular exercise or a rather sedentary state performing daily activity only. Four groups were Placebo-control group (n = 16), Placebo-exercise group (n = 16), Isoflavone-sedentary group (n = 19) and Isofla-vone-exercise group (n = 16). After the intervention, we compared anthropometric mesurement, dietary recall, bone mineral density (femoral neck, lumbar spine), urinary deoxypyridinoline between the groups and between the pre and post studies. There were no significant differences between the four groups in terms of average age, height, weight, period after menopause at the baseline. The average age of the subjects were 55.2 yrs, average height, weight, period after menopause were 154.7 cm, 59.3 kg, 5.58 yrs, respectively. After eight week intervention period, there were no significant differences between the four groups in bone mineral density, but urinary deoxypyridinoline excretion was significantly decreased both in Isoflavone-sedentary and Isoflavone-Exercise groups. These results suggest that Isofla-vone supplementation alone or with exercise may be preventive measures through the decrease of bone reabsorption rate in post-menopausal subjects. Whereas exercise alone did not appear to be an effective measure in bone loss with these subjects.

This study was done to determine a new qualitative base for educating and evaluating patients by comparing a 60 or over age group with a 20-30 age group when rising from supine to erect stance. Sixty normal adults were devided into 60 or over and 20-30 aged groups. Each persons was asked to standing from the supine position. This process was recorded by two video cameras. The results was classified into the three existing movement categories. And then they were analyzed by percent rate. The results showed that each group had its own different and special characteristics. This means that physical therapists need to select the best motor patterns according to age in teaching functional tasks such as rising from supine to erect stance.

The purpose of this study is to find out a flow characteristics when a crossflow-fan is installed inside the computer case and to provide information about the preliminary data of cooling efficiency of CPU and a flow inside and outside of a computer case. Under the condition of operating the fan inside the experimental duct we changed the position of a installation of the slot, and the experiment measured with PIV and the results are as follows. Under the influence of the crossflow-fan installed to the air discharging side, mean velocity between 35 to 45 on the point 80 of the Slot 0.2.3 of the case increased and it influences discharging the air inside of the computer case. On the left-upper end. which isn't directly influenced by the suction-discharging fan installed inside the PC, a flow occurs caused by vortex due to the Sirocco-Fan and Slot installed on the center of the right side. We can see that a flow distribution increases when the Sirocco-Fan operates and a whirl appears stronger between the slot and the suction fan. It is thought that this phenomenon is influenced by a flow while it is on the way of entering from the suction-fan and going out to the discharging-fan.

Purpose: The purpose of this study was to investigate the effects of a cardiac rehabilitation program for patients with myocardial infarction. Method: The subjects were 45 myocardial infarction patients(22 for experimental group and 23 for the control group). Data were collected through questionnaire survey, blood test, and the treadmill test, between October 1, 1999 and December 31, 2000. As for data analyses, paired and unpaired t-test and $\chi^2$ test were adopted using the SAS program. Result: 1. The post-test revealed that increase in compliance score of health behavior was significantly higher in the experimental group than in the control group. 2. The increase in HDL cholesterol was significantly higher in the experimental group than in the control group, in the post-test. 3. The experimental group showed significantly higher duration of exercise time and maximal METs than the control group after the program. Conclusion: The above findings indicate that a cardiac rehabilitation program was effective in increasing compliance of health behaviors, serum HDL cholesterol level, duration of exercise time, and maximal METs in patients with myocardial infarction. Accordingly, we can adopt the individualized cardiac rehabilitation programs as a nursing intervention.

본 연구에서는 Argyres-Sigel의 투영 연산자 방법을 단일 벽 탄소 나노튜브(SWNT)의 zigzag(10,0)에 직접 적용하여 이를 운동방정식의 형태로 만들어 선모양 함수를 구하는 방법을 사용하였다. 선모양 함수의 실수 부분인 선 너비는 저온 영역(T < 200K)에서 온도의 영향에 거의 무관한 것으로 조사되었다. 이는 온도에 관여하는 페르미-디랙 분포함수가 선모양 함수에 거의 영향을 작용하지 않기 때문인 것으로 생각된다. 고온 영역(T > 200K)에서는 선 너비가 다소 단조롭게 증가하는 것으로 나타났으며, 이는 음향 포논의 영향에 기인하는 것으로 보인다. 그리고 SWNT의 전자스핀이완 시간은 $1.4{\times}10^{-6}\;s$으로 계산되었다.

Objective : The purpose of this study was to conduct biomechanical analysis of varying backpack loads on the lower limb movements during downhill walking over $-20^{\circ}$ ramp. Method : Thirteen male university students (age: $23.5{\pm}2.1yrs$, height: $175.7{\pm}4.6cm$, weight: $651.9{\pm}55.5N$) who have no musculoskeletal disorder were recruited as the subjects. Each subject walked over $20^{\circ}$ ramp with four different backpack weights (0%, 10%, 20% and 30% of body weight) in random order at a speed of $1.0{\pm}0.1m/s$. Five digital camcorders and two force plates were used to obtain 3-d data and kinetics of the lower extremity. For each trial being analyzed, five critical instants were identified from the video recordings. Ground reaction force, loading rate, decay rate, and resultant joint moment of the ankle and the knee were determined by the inverse dynamics analysis. For each dependent variable, one-way ANOVA with repeated measures was used to determine whether there were significant differences among four different backpack weight conditions (p<.05). When a significant difference was found, post hoc analyses were performed using the contrast procedure. Results : The results of this study showed that the medio-lateral GRFs at RHC in 20% and 30% body weight were significantly greater than the corresponding value in 0% of body weight. A consistent increase in the vertical GRFs as backpack loads increased was observed. The valgus joint movement of the knee at RTO in 30% body weight was significantly greater than the corresponding values in 0% and 10% body weight. The increased valgus moment of 30% body weight observed in this phase was associated with decelerating and stabilizing effects on the knee joint. The results also showed that the extension and valgus joint moments of the knee were systematically affected by the backpack load during downhill walking. Conclusion : Since downhill walking while carrying heavy external loads in a backpack may lead to excessive knee joint moment, damage can occur to the joint structures such as joint capsule and ligaments. Therefore, excessive repetitions of downhill walking should be avoided if the lower extremity is subjected to abnormally high levels of load over an extended period of time.
