SG-365 steel is an important material and used for manufacturing a pressure vessel which the gas piping. In this investigation, the elastic plastic fracture toughness of this material is evaluated by the an unloading compliance method according to the ATM E813-97 method on the smooth and side groove 1CT specimens. The effect of smooth and side groove is studied on the elastic plastic fracture toughness. The side grooved specimen is very useful in estimation of the $J_IC. Because it is much easier than the smooth specimen to the onset of the ductile tearing by the R curve method. Besides, it improves the accuracy of toughness values, decreases the scattering of them and tunneling and shear lip by the side groove.

Gastrointestinal side effects including nausea and vomiting, diarrhea, constipation, oral mucositis and colitis, and hepatotoxicity are common occurrence during chemotherapy. Often they result in unplanned admission and interruption of scheduled therapy. Additionally they have a negative influence on patient's therapeutic outcome and quality of life. The assessment of gastrointestinal side effects is dependent on clinician assignment of a grade established by the National Cancer Institute Common Terminology Criteria for Adverse Events. Continued interest of gastrointestinal side effects has allowed identifying patients at higher risk and providing effective treatments to relieve painful symptom. Finally, proper prevention and management of chemotherapy-induced gastrointestinal side effects will be needed to improve patient's survival and quality of life.

The purpose of this study was to investigate the effect of proprioceptive neuromuscular facilitation (PNF) approach on the spasticity of affected side in patients with hemiplegia. Three subjects with hemiplegia participated in this study. In single-subject research design (a multiple baseline across individuals) was employed in this study. The intervention program including PNF to the unaffected side was introduced for 30 minutes each day during each intervention phase. Muscle tone of affected side was measured with Tone Assessment Scale, and active hip abduction distance of affected side was taken with the subject supine. And then the muscle tone and the hip abduction distance were measured again 30 minutes later following the intervention. The results showed that the PNF application had some beneficial effects on both muscle tone and active hip abduction. This result suggest that PNF application to non-paretic limb can be effective in reducing muscle tone and improving hip abduction range on paretic limb in persons with hemiplegia. However, further research is needed to prove the effect of PNF application on functional improvement.

The purpose of this study is to invesigate the effect of Yook-Gun-ja-Tang on the side effect of cyclophosphamide to splenical tissue in the rat. The experimental animal were divided into normal group, control group, sample group by way of method treatment of the drug. Each group was sacrificed and stained in accordance with the schedule and observed under light microscope. The results of this study were as follow : 1. After treatment of Yook-Gun-Ja-Tang, rat's weight and volume were more increased than normal group and control group. 2. The decrease of the numbers of the splenical tissue after administration of cyclophosphamide were recovered with prescription of the Yook-Gun-la-Tang ; The decreases of white pulp, red pulp, marginal zone, central artery were recovered. 3. Increased macrophages in red pulp of splenical tissue of rats with administration of cyclophosphamide were decreased after treatment of Yook-Gun-Ja-Tang. These results appeared to suggest that Yook-Gun-Ja-Tang might be effective on the: side effect of cyclophosphamide to splenical tissue of rat's and applied to the prescription for the recovery of the side effect of drug.

In this paper, the generation of high pretilt angle in nematic liquid crystal (NLC) by dipping effect on three kinds of the rubbed polyimide (PI) surface was investigated. The generated pretilt angle of NLC increases due to dipping effect before rubbing treatment on two kinds of the rubbed PI surface with side chain. The generated pretit angle in NLC by using dipping effect after rubbing treatment on PI surface with short side chain is high compared to the PI surface with long side chain. The generated pretit angle of the positive type NLC $(\Delta{\varepsilon}>0)$ is higher as than that of the negative type NLC $({\Delta}{\varepsilon}<0)$ by using dipping effect before rubbing treatment on homeotropic layer. The generated pretilt angle of NLC is attributed to perpendicular component of permittivity ${\varepsilon}_{\perp}$ of NLC on rubbed PI surface.

Purpose : The purpose of this study was to investigate the effect of side planks on the muscle thickness of the core muscles, external oblique, internal oblique, and transverse abdominis, and this study was conducted to compare whether side plank exercise according to the application of various unstable support surfaces increases the thickness by activating the action of the muscles. Methods : The subjects of this study were 30 healthy adults and were randomly and equally assigned to three groups by a random number table. All subjects were divided into three groups according to the application of an unstable support surface during the side plank(Group A = stable support, Group B = one unstable support, Group C = two unstable supports). The side plank exercise was performed 30 minutes a day, 3 times a week for a total of 4 weeks. The muscle thickness of the core muscle was measured before the intervention, 2 weeks, 4 weeks, and 3 times in total. All measured data were comparatively analyzed by repeated measures ANOVA and one-way ANOVA. The statistical significance level was set to .05. Results : The results of this study were as follows : 1. All muscles showed an interaction between training period and group. 2. There was a significant difference between the groups at the 2 weeks and 4 weeks of the internal oblique and transverse abdominis muscle measurements. Conclusion : The thickness of the abdominal muscle increased during the side plank exercise according to the support surface, and the thickness of the abdominal muscle increased the most during the side plank exercise on the unstable support surface. Therefore, it is thought that the addition of an unstable support surface will provide a more effective therapeutic effect on the thickness change of the abdominal muscle during side plank exercise.

이 논문은 CC 프로세스의 movable side trowel 효과를 연구하기 위한 실험과 모델링을 제시한다. FEA simulation을 이용하여 우리는 movable side trowel의 효과와 움직임에 대한 기초적인 이해를 얻어냈다. 단면의 side trowel 보다 양면의 side trowel이 실제의 3D 형상을 만드는 동안에 층간의 최적의 결합을 만들어 준다는 면에서 가장 적합하다는 것을 알아냈다. 우리의 실험이 위의 결과를 입증하였다.

Behavior of the side force generated at high angles of attack by two ogive-cylinder bodies of revolution with nose fineness ratio of 2.3 (B1) and 3.5 (B2) and the effect of a strip placed close the nose tip of each body (B1S and B2S) are analyzed through the wind tunnel test at ReD=200,000 and a=42~60 deg. The side force generated by B1 is increased by placing a strip. The side force generated by B2 is in the starboard direction and its magnitude is higher than that of the B1S. The effect of the strips with various dimensions placed on B2 is investigated. It is found that the 4-layer strip placed on the starboard reversed the direction of the side force into port direction. It is confirmed by numerical simulations that the strip promotes the flow separation and increases the average pressure on the side where it is placed and consequently produces the side force in the corresponding direction.

The purpose of this study was to investigate the effect of wearing a soft knee brace during balance training on paretic side foot pressure and knee joint muscle strength in stroke patients. The recruited 20 stroke patients were randomized into 10 experimental group and 10 control group. All subjects were subjected to balance training, and only the experimental group was trained in balance while wearing a soft knee brace. Experimental group and the control group before and after the intervention showed significant increases in foot pressure and knee joint muscle strength on the paralyzed side (p<0.05), experimental group showed a significant increase in foot pressure and knee joint muscle strength compared to the control group (p<0.05). This study confirmed that wearing a soft knee brace had a positive effect on paretic side foot pressure and knee joint muscle strength in stroke patients.
