The experiments were carried out during a total of nine sessions, that is, 3 sessions over 3 days. The CK levels decreased depending on the experiment session ($P{\leq}0.05$), but there was no significant difference ($P{\leq}0.05$) between the experimental group and the control group. Pressure threshold levels significantly decreased depending on the experiment session and the treatments had higher effects in the experimental group. VAS figures significantly decreased depending on the experiment session ($P{\leq}0.005$) and the treatments had higher effects in the experimental group. The results of this study verified the contention that applying vibration treatment immediately after inducing DOMS is more effective in terms of pressure pain threshold (PPT) and VAS, but not CK levels, than applying the treatment 24 hours after inducing DOMS. In addition, the experimental group showed a statistically significant difference compared to the control group. Therefore, it was concluded that applying vibration treatment immediately after inducing DOMS can be used as a DOMS treatment method.

Cervical disc herniation is one of the most common causes of neck, shoulder and arm pain. There are many treatments for a cervical disc herniation, such as rest, physical therapy, medication, epidural steroid injection and surgery. However, conservative treatments sometimes have limited effectiveness, and a surgical discectomy is often associated with numerous complications. Nowadays, a percutaneous discectomy, using a $Dekompressor^{(R)}$, has been used in herniated disc patients, but a posterolateral extruded disc is not an indication. Herein, our experience using a 19 G $Dekompressor^{(R)}$, on a 52 year-old male patient with a left C6-⁣7 posterolateral extruded disc, is reported. Decompression was successfully performed, and the pain and range of motion was immediately improved.

Hardened layer and compressive residual stress created by carburized treatment effect on bending fatigue strength of gear massively. Also, shot peening treatment improves the strength of carburized gear as it does the hardness and residual stress of surface layer. In these days shot peening techniques are welcomed as one of physical improvement ways around the surface of materials. It is used widely because qualitative analysis of shot peening has become possible and surface treatment can be done with very little costs compared to other surface improvement methods. Therefore this study investigates the effect of shot peening in surface shape and bending fatigue strength after doing many kinds of shot peening treatments, then doing fatigue test and also explained characteristics of shot peening gear.

Physical metallurgy aspects of gaseous ferritic nitrocarburising are reviewed in the light of basic studies undertaken since 1975 which have illustrated inconsistencies between the iron-carbon-nitrogen ternary phase diagram at $570^{\circ}C$ and the experimental observation of the co-existence of the ${\varepsilon}$ carbonitride phase and ferrite. Thermodynamic investigations by Xu and Li together with those by Slycke et al are reviewed to illustrate compatability between a modified isothermal section of the Fe-C-N system and the formation and growth of a monophased ${\varepsilon}$ structure under a variety of processing conditions. The implications of the modified diagram in terms of innovations in industrial ferritic nitrocarburising practice are discussed, together with limitations on the control of the process. The importance of the developing technology of black nitrocarburising for enhanced wear, fatigue, and corrosion resistance is emphasised. Basic studies and industrial status of austenitic nitrocarburising treatments are also reviewed, which highlight the importance of substrate strengthening for high load bearing applications of anti-scuff thermochemical treatments.

Objectives: The purpose of this study is to report the effect of Korean medicine treatments on Postoperative symptoms. Methods: The patient was treated with herbal medicine, acupuncture and electronic moxibustion. The efficacy of treatment was evaluated with visual analogue scale (VAS), the degree of symptom relief and presence or absence of symptoms. Results: After hospital care with korean medicine treatments, symptoms such as fatigue, lower abdominal pain, thirst, hot flush, cold hypersensitivity of hands and feet and tinnitus were disappeared. Conclusions: To promote physical strength and reduction of fatigue, intensive hospital care with korean medicine treatment seems to be effective. After discharge, continued outpatient treatment for complications of surgery and menopausal disorder seems to contribute to quality of life and satisfaction for patient who undergoing hysterectomy.

Purpose: Many studies have reported increased muscle activities in treatments using kinesio tape. However, most studies have focused on only muscles, so the effects of kinesio tape on structures other than the muscles are unknown. The purpose of this study is to explore the effect of kinesio tape for the fascia on trunk muscle activity during plank. Methods: Eighteen healthy participants took part in this study. The participants were asked to perform the plank in two conditions: on stable surface and unstable surface. Two kinesio tapes were attached along the spiral line introduced in the anatomy train. EMG was measured in each condition. EMG data were collected before and after attaching kinesio tape in each condition. Repeated analysis of variance (repeated ANOVA) was conducted to compare EMG activities levels between conditions. Results: EMG activities levels of trunk muscles, especially rectus abdominis and erector spinae activities were significantly increased during the plank with KT on both stable and unstable surfaces. Conclusion: KT applying on the fascia of targeted muscle increases the muscle activity. Therefore, we can also focus on the fascia to increase muscle activities not only on muscles.

The purpose of this study is to compare the outcomes of manual stretching treatment with those of motor development and positioning physical therapy (MDPPT) for congenital muscular torticollis (CMT). This study was designed to be randomized controlled trials and to evaluate the outcomes of 43 consecutive patients with CMT who were first seen when they were average 26 days old. Before treatments, the patients were unintentionallv classified into two clinical groups along with the treatment methods. Among the 43 patients, 22 were classified to the manual stretching group and 21 to the MDPPT group. By means of independent t-test on the result. the duration of treatment according to methods was not significantly different in two groups (p>.05). The duration of treatment in accordance with head tilt level was not significantly different in two groups (p>.05). There was change of mass diameter, between at the beginning day of treatment and after treatment in manual stretching group with a strong positive linear correlation (p=.000, r=.734), but slightly positive linear correlation in MDPPT group. The result of this study indicates that two therapeutic methods make little difference in effectiveness.
