This study was conducted to confirm the effect of vibration on muscle activity in IASTM. The subjects were 20 healthy adults. The intervention applied in this study was IASTM applied to the biceps brachii muscle. In the case of the experimental group, unlike the control group, the vibration function was turned on when IASTM was applied. The interventions for each group were applied, and the muscle activity of the biceps brachii muscle was measured before and after the intervention. All measured values were calculated as %MVIC values, dependent t test and independent t test were performed and analyzed for comparisons. As a result of this study, only in the control group, the muscle activity of the biceps brachii muscle after the intervention was significantly decreased compared to before the intervention. When vibration is applied together with IASTM, the relaxation effect is reduced, which is considered to be inappropriate for treatment.

Odontogenic myxoma of the jaws is a rare benign odontogenic tumor. In this case, a 61-year-old male patient had a chief complaint about maxillary anterior gingival mass and excisional biopsy result confirmed odontogenic myxoma. The clear acrylic resin custom tray was designed to minimize displacement of flabby tissue which remained after the surgery. Neutral zone and external impression technique could provide satisfactory result in terms of denture stability and retention during jaw relation record and wax denture try-in procedure. This clinical report describes fabrication of complete dentures for a patient with odontogenic myxoma in regard to flabby tissue and neutral zone.

This study was conducted to observe the difference in muscle activity by IASTM between a tool made of PLA made with a 3D printer and a tool made of ready-made stainless steel. This study was attended by 10 adults in their twenties, and all subjects participated in both the PLA group and the Stainless group, received IASTM. %MVIC was measured by measuring muscle activity after intervention, and this was verified through comparison between groups through the Mann-Whitney U test. The results of this study showed that there was no significant difference between the two groups in the %MVIC value of the biceps brachii after intervention. Therefore, in the application of IASTM, there was no difference in muscle activity depending on the material of the tool, which seems to be that the IASTM tool made of PLA made with a 3D printer produced similar results in the ability to control neuromuscular muscles and the ready-made product made of stainless steel. Therefore, in a future study, the effectiveness of the tool will be verified for the various patient group.

월성1호기 압력관의 수소흡수 관련 자료들을 분석하였으며, 캐나다 발전소들의 결과와도 비교하였다. 압력관의 수소흡수 특성은 압력관내 위치, 사용온도, 가동이력 등에 영향을 받아 Inlet 쪽보다는 Outlet 쪽이, 사용온도가 높을수록, 또한 가동에 따른 조사량이 증가할수록 수소흡수량이 증가하였다. 한편 압력관내로의 수소흡수 거동을 규명하기 위해 Zr-2.5wt%Nb 합금의 열처리 조직 차이에 따른 수소흡수특성을 분석하였다. 수소흡수는$\alpha$-Zr 상에 비해 $\beta$-Zr, $\beta$-Nb 상에 크게 영향을 받는 것으로 보인다. 또한 합금내의 수소량 증가가 압력관 부식특성 자체에 미치는 영향을 분석하기 위하여 열처리 시편에 일정량의 수소를 charging 시킨 후 부식시험을 수행하였다. Zr-2.5wt%Nb 합금의 부식거동은 미세조직에 가장 큰 영향을 받아$\alpha$-Zr과 $\beta$-Zr 상의 시편이$\alpha$-Zr과$\beta$-Nb 상의 시편에 비해 큰 부식속도를 보였다. 또한 시편내 150ppm 이하의 수소함량은 시편의 부식거동에 별다른 영향을 없거나, 부식속도를 약간 감소시키는 것으로 추정된다.

This study investigates the effects of instrument-assisted soft mobilization (IASTM) and manual myofascial release (MFR) on the muscle activity of the biceps brachii. This study was conducted on 10 men and women in their 20s, and all subjects participated in the experiment for 3 days and measured muscle activity of the upper forearm muscles. On the first day, the muscle activity value was measured before the intervention, and the remaining two days were measured for muscle activity after the intervention of each manual therapy in a random order. All muscle activity values were compared and analyzed through the dependent t test and the independent t test. The before and after comparison of muscle activity values before and after each intervention was verified by performing the dependent t test and comparing the values of muscle activity between groups between each intervention after intervention by performing an independent t test. According to the results of this study, both interventions significantly increased muscle activity of the biceps brachii before and after intervention, and there was no significant difference in muscle activity values between groups after intervention. Therefore, both manual therapy (IASTM, MFR) are thought to be effective in improving neuromuscular control ability.

TTH(tension-type headache) is the most common primary headache among adults. Long-term headaches cause chronic headaches and have a better impact on daily life. The purpose of this study is to compare the contributions to TTH through AVE(audio-visual entertainment) and STM(soft tissue mobilization) suitable for management of pathogenic and psychogenic factors of TTH. The participants of this study were from 30 people who complained of intermittent or persistent headaches for more than 6 months, and 10 participants each in the AVE group, STM group, and AVE plus STM group. In the assigned group, a total of 12 sessions were performed three times a week for 4 weeks after the baseline, followed by post-test. Outcome measures measured PPTs(pressure pain thresholds), psychophysiological parameters, and EEG(electroencephalogram). The measured results were analyzed for interaction between time and group through a two way rmANOVA(repeated measurement variance analysis). As a result of the PPTs, interaction was found in the results of the right trapezius (p<.05), and the more improvement was observed in the AVE group. Therefore, through AVE based on psychological factors rather than direct access to the muscles of pathogenic factors, a positive impact on the PPTs was shown, but the average value of the psychophysiological parameters and brain waves that were not statistically significant. The amount of change was observed. Through this, it is suggested that audio-visual stimulation could be considered in the management of TTH.

경쟁 정보(CI)는 다른 기업들에 비해 그들의 IT 하부조직의 상대적인 강점과 약점을 명확히 하는데 도움이 된다. 정보 기술의 변화가 급속하고 때로는 극적이기까지 한 시대에 CI는 그러한 기술이 야기하는 위기와 기회를 확인하는데 도움이 된다. 그러므로 CI는 예산기획과 전략기획을 개발하고, 실행하고, 개선하는 것 뿐만 아니라 알려진 정보기술을 관리하는데도 유용하다.

This study was conducted to investigate the effects of upper thoracic joint mobilization technique using Kaltenborn-Evjenth concept on the range of cervical and thoracic motion and pain in patients with chronic neck pain. The subjects were divided into a thoracic joint mobilization group(n=7) and a conservative physical therapy group(n=7). Each of the groups received thoracic joint mobilization or conservative physical therapy three times a week lasted for four weeks. The measurements were performed for the range of thoracic segmental motion(SpinalMouse), the pain(visual analogue scale) and the range of cervical joint motion(Inclinometer, Dualer IQ). They were made four times: before experiment, at 2weeks, 4weeks, and 4weeks after experiment.
