Purpose : To evaluate the effects joint mobilization and McKenzie exercise on the cervical range of motion and tenderness through cervical range of motion(CROM), algometer. Methods : The subjects consisted of thirty five patients. Eighteen underwent McKenzie exercise, seventeen did Joint Mobilization. The joint mobilization group received joint mobilization exercise for about 15 minutes, and McKenzie exercise group received extension, side-flexion, flexion, elevation, exercise for 15 minutes respectively. The test period of each group took place three times a week during 6 weeks. All measurements for each the subject took the following treatment: pre-treatment, treatment in 2 weeks, treatment in 6 weeks, post-treatment in 2 weeks. Results : The flexion, extension and side-flexion CROM of both groups were statistically significant increase within treatment period(p<.05), and also a significant difference within pre-treatment and post-treatment in a 2 week period(p<.05), within treatment in 2 weeks and post-treatment in 2 weeks by checking the extent of effect in the treatment period(p<.05). The trapezius tenderness threshold of both groups were statistically significant increase within treatment period(p<.05), and also significant difference within pre-treatment and post-treatment, within treatment in 2 weeks and post-treatment by checking the extent of effect in the treatment period. Conclusion : Joint mobilization and Mckenzie exercise improved cervical range of motion and tenderness threshold.

The effect of Panax ginseng administration in muscle inflammatory process induced after eccentric exercise, that causes myofibrillar disruption, was studied. Changes in lipid peroxidation, inflammation, glycogen levels in muscle and release of myocellular proteins to blood were measured. The analyses were performed immediately after eccentric exercise and over week since this period are necessary for the muscle damage-repair cycle. The ginseng extract (100 mg kg$^{-1}$ ) was orally administered to rats for three months, before the eccentric exercise performance. The results showed the protective role of ginseng against skeletal muscle damage. This effect could be associated with their membrane stabilising capacity since creatine kinase (CK) activity was significantly decreased 96 h post-exercise from 523$\pm$70 to 381$\pm$53 and 120 h post-exercise from 443$\pm$85 to 327$\pm$75 in treated animals. $\beta$-glucuronidase activity, as indicator of inflammation, showed a significant reduction of about 15-25% in soleus, vastus and triceps in these post-exercise times. The lipid peroxidation, measured by malondyaldehyde levels, was significantly decreased in the 24 h post-exercise period in soleus and vastus intermedius muscles and on the recovery period. Finally ginseng administration reduced significantly the decrease of the glycogen levels immediately after exercise and when the regenerative process took place (72-168 h post exercise). Collectively, the results have showed that ginseng did not inhibit the vital inflammatory response process associated with the muscle damage-repair cycle but presumably ameliorate the injury.

Objectives: Hydrogen peroxide ($H_2O_2$) surface treatment of fiber posts has been reported to increase bond strength of fiber posts to resin cements. However, residual oxygen radicals might jeopardize the bonding procedure. This study examined the effect of three antioxidant agents on the bond strength of fiber posts to conventional and self-adhesive resin cements. Materials and Methods: Post spaces were prepared in forty human maxillary second premolars. Posts were divided into five groups of 8 each: G1 (control), no pre-treatment; G2, 10% $H_2O_2$ pre-treatment; G3, G4 and G5. After $H_2O_2$ application, Hesperidin (HES), Sodium Ascorbate (SA) or Rosmarinic acid (RA) was applied on each group respectively. In each group four posts were cemented with Duo-Link conventional resin cement and the others with self-adhesive BisCem cement. Push-out test was performed and data were analyzed using 2-way ANOVA and tukey's post-hoc test (${\alpha}=0.05$). Results: There was a statistically significant interaction between the cement type and post surface treatment on push-out bond strength of fiber posts (p < 0.001, F = 16). Also it was shown that different posts' surface treatments significantly affect the push-out bond strength of fiber posts (p = 0.001). $H_2O_2$ treated posts (G2) and control posts (G1) cemented with Duo-link showed the highest ($15.96{\pm}5.07MPa$) and lowest bond strengths ($6.79{\pm}3.94$) respectively. Conclusions: It was concluded that $H_2O_2$ surface treatment might enhance the bond strength of fiber posts cemented with conventional resin cements. The effect of antioxidants as post's surface treatment agents depends on the characteristics of resin cements used for bonding procedure.

디지털 몰핑은 영화의 내러티브를 효과적으로 표현하면서 현실 넘어서는 상상을 사실로 구현한다. <블랙 스완>(2013)에서 디지털적으로 구현된 몰핑 이미지는 포스트 시네마로서 오늘날 영화의 특징을 잘 보여주고 있는데, 컴퓨터 기술을 적극적으로 활용해 마술 같은 환각적 이미지를 제공한다. 디지털 몰핑 기술은 주인공이 발레를 추는 동안 기괴하게 변형되어 가는 신체를 현실과 환영이 구분되지 않게 제시함으로써 충격을 준다. 이러한 이미지는 어트랙션 효과로 그치지 않고 신자유주의 시대의 강도를 정동의 흐름으로 가시화해 낸다. 신체 변형의 기이한 효과는 신자유주의 현실의 징후인 것이다. 또한 이러한 몰핑 이미지는 파트리샤 피스터스가 말한 신경-이미지 체제의 부상을 말해준다. 디지털 스크린에 나타난 신경 병리학적인 양상들은 신경-이미지에 해당되는 것으로, 들뢰즈의 시간-이미지 체제를 넘어서 미래의 시간성을 띤다. <블랙 스완>의 몰핑의 경우 니나의 신체가 흑조와 혼종화 되어서 계속적으로 변화하는 동안 신경-이미지적인 특성이 두드러지게 나타난다. 신경 이미지로서 이 영화의 디지털 몰핑은 주체가 겪는 현실의 충격을 조절하는 효과를 지닌다. 이 영화의 몰핑은 디지털 시대의 사회적 통제의 효과이자 그 통제를 조절하는 포스트 시네마의 역량을 보여주고 있다.

The response of a reinforced concrete element under cyclic shear is characterized by the hysteretic loops of the shear stress-strain curves. These hysteretic loops can exhibit strength deterioration, stiffness degradation, and a pinched shape. Recent tests have shown that the orientation of steel grids in RC shear elements has a strong effect on the "pinching effect" in the post-yield hysteretic loops. When the steel grid was set at a 45 degree angle to the shear plane, there was no pinching effect and no strength deterioration. However, when the steel grid was set parallel to the shear plane, there was a severe pinching effect and severe strength deterioration with increasing shear strain magnitude. In this paper, two RC elements subjected to revered cyclic shear stresses are considered to study the effect of the steel grid orientation. The presence and absence of the pinching mechanism in the post-yield shear hysteretic loops is studied using the Rotating Angle Softened Truss Model (RA-STM) theory.

This study tried to find the effect to the representation patterns of science concepts upon the momentum effect. The previous studies showed that the momentum effect is influenced by students' cognitive levels and the abstractness of test items. The representation patterns of science concepts are divided into 4 different types: quantitative and qualitative, verbal and image. The research method used in this study is time series design. The period is 50 days. The period is divided into "pre-lest", "intervention-test", "post-test". Pre-test period is 5 days and in this period class instruction does not exist. Intervention-lest period is 30 days and in this period class instruction exist. Post-test period is 15 days and in this period class instruction does not exist. The results showed longer momentum effect on the image-qualitative representation pattern than the other representation patterns. Qualitative concepts is formed better than quantitative. Momentum effects is not artifact but the essential characteristics of science study.

In this paper resistance projection weldability of Zn coated steels with post treatment has been discussed. Projection welding was performed by a condenser discharge type power source which was equipped with welding parameter monitoring system. Mechanical test results indicated that the effect of post coatings on the projection front changed showing very small very small spattering at the weld strength was negligible. However, contamination rate of the block electrode varied depending on the post treatment coatings. Test results also showed that projection height before welding should be kept to be 80-100% of the specimen thickness as far as the surface quality was taken into consideration. Based on the high speed photography, discharge condition at the beginning stage of the welding process. It was considered that the spattering reduced the weld strength slightly at the optimum heat input range.
