Purpose: The purpose of this study was to evaluate the impact of a protocol of cryotherapy and Tai Chi on women with Fibrolmyalgia Syndrome. Methods: The study design was a pretest and posttest quasi-experimental, nonrandom assignment. The subjects were 48 outpatients with a diagnosis of fibromyalgia based on the American College of Rheumatology Standards. The setting was a University Medical Center in S city. The protocol was self administered ten times a week, for a two week period resulting in twenty treatments. Results: A protocol of cryotherapy and Tai Chi self-help program showed significant improvement in the fibromyalgia impact as measured by reports of physical impairment, feeing good, number of missed work days, ability to perform work, reports of pain, fatigue, rest, stiffness, anxiety and depression as reported by the comparison group (p<.001). No significant differences between the two regarding in reports of the tender points (p=.062). Conclusion: The results suggested that a protocol of cryotherapy and Tai Chi self-help program may be a promising multidisciplinary strategy for fibromyalgia patients.

In this paper, the performance of a domestic Kim-Chi refrigerator is predicted by using a calculation model & experiment. The objectives of this study are to find out the best design points of a refrigeration system and calculate an adiabatic characteristic to change outdoor temperature. The best design points such as refrigerant charge and capillary length were experimentally investigated. And the calculation model is conducted as a function of calculation parameters and outdoor temperature. According to this study results, the best design points of a refrigeration system are each 95g of a refrigerant charge and 3500/3500mm of capillary lengths. And the power consumption is 13.578 Kwh/month. And a part of the worst heat loss is a front side of a domestic Kim-Chi refrigerator body.

Let $S\;=\;R[\chi_{ij}\mid1\;{\le}\;i\;{\le}\;m,\;1\;{\le}\;j\;{\le}\;n]$ be the polynomial ring over a noetherian commutative ring R and $I_p$ be the determinantal ideal generated by the $p\;\times\;p$ minors of the generic matrix $(\chi_{ij})(1{\le}P{\le}min(m,n))$. We describe a minimal free resolution of $S/I_{p}$, in the case m = n = p + 2 over $\mathbb{Z}$.

In this research, a computer analysis has been developed for predicting the Pipe pressure of the intake and exhaust manifold in a small single cylinder engine. To get the boundary conditions for a numerical analysis one dimensional and unsteady gas dynamic calculation is performed by using the MOC(Method Of Characteristics). The main numerical parameters are engine revolutions. to calculate the Pulsating flow which the intake and exhaust valves are working. The distributions of the exhaust pipe pressures were influenced strongly to the cylinder pressures and the shapes of exhaust pressure variation were similar to the Inside of cylinder pressure As the engine revolutions are increased. the intake pressure was lower than ambient pressure. The amplitude of exhaust pressure had increased and the phase of cylinder pressure $P_c$ is delayed and the amplitude of cylinder pressure were increased.

Purpose: The purpose of the study was to compare the effects of Tai Chi exercise, Tai Chi self help program, and self help management program on arthritic pain, stiffness, fatigue and difficulties in performing daily activities in patients with osteoarthritis. Method: The pre-post experimental design was utilized with convenient sampling at Public Health Centers. Total of 38 subjects agreed to participate in the study with the inclusion criteria of being diagnosed as osteoarthritis and no previous regular exercise. The 12 subjects were assigned to Tai Chi exercise group, 13 subjects to Tai Chi exercise combined with self help management program, and the other 13 to self help management program. Tai Chi exercise group performed exercise twice a week for one hour per each session. Tai Chi self help management group came to the class twice a week, one hour for Tai Chi exercise, and another hour for self help management program. The third group came to the class once a week for one hour to participate self help management program. At the completion of 6 week programs, 10 subjects from Tai Chi exercise, 9 from Tai Chi self help, another 10 from self help management groups completed the post-test measures. The data were analyzed by SPSSWIN 11.0. The homogeneity tests for three experimental groups were conducted by $X^2-test$, Fisher's exact test, Kruskal-Wallis test. The final analysis of the post-test measures was conducted by ANCOVA with fatigue, pain, stiffness, and difficulties in daily activities of the pretest measures as covariates. Results: The results were as follows. There were no significant differences in fatigue, pain, and difficulties of daily activities among three groups for the pretest measures. The score of arthritic stiffness was significantly different among groups after controlled for covariates, but the post-hoc tests showed no group differences. Conclusion: The nursing interventions applied for osteoarthritis patients have been previously tested to show the cost effectiveness of symptoms management of this population.

Successive image contrast enhancement was used to direct digital radiography system. This system was accurately required acquisition signal in each pixel. But, applied high electric field in a-Se thin film for x-ray conversion layer was caused to acquisition signal distortion, then bring low image contrast. The purpose of this study was to reduce the signal distortion, carried out different electrode size.
