        Background: Studies using Smovey and Vibration foam rollers are mostly conducted with normal adults, breast cancer patients, and athletes. However, there are not many studies applied to stroke patients to date. Objectives: The purpose of this study is to investigate the effect of vibration exercise on the range of motion of the shoulder and knee joints in stroke patients. Design: A randomized controlled trial. Methods: A total of 36 stroke patients, with 12 in the Smovey and Vibration foam roller group (SVG), 12 in the Smovey and Non-Vibration foam roller group (SNVG), and 12 in the control group (CG) were randomly assigned to exercise three times a week for 6 weeks. The range of motion of the shoulder and knee joints was measured for each group before and after 6 weeks of exercise. For joint range of motion, shoulder flexion and extension and knee flexion and extension were measured using BPMpro. Results: In terms of the difference in time, the flexion and extension of the shoulder and the flexion and extension of the knee on the paretic side were significant in the SVG and SNVG. The CG was not significant. Shoulder flexion and extension and knee flexion and extension on the unaffected side were all insignificant. The differences between each group were significant between the SVG and the CG and the SNVG and the CG. SVG and SNVG were not significant. Conclusion: It was found that vibration exercise had a positive effect on the range of motion of the shoulder and knee joints. Therefore, it is thought that vibration exercise can be provided as a clinical intervention method for shoulder and knee range of motion.

        Background: A functional movement screen (FMS) can be used as an intervention method as well as a test method. Compensatory action due to a faulty functional movement result in imbalance of the body, and decrease in proprioceptive sensation and flexibility. However, the benefits of exercise using FMS on proprioceptive sensation and flexibility are unclear. Objectives: This study aimed to investigate the effect of exercise using FMS on the proprioceptive sensation and flexibility. Design: Pretest-posttest control group experimental design. Methods: Fifty-two young adults in their 20s were divided into an FMS exercise group (FEG, n=26) and a control group (CG, n=26). The FEG conducted FMS exercise intervention for 12 days, and CG did not implement any intervention. Each group evaluated proprioceptive sensation and flexibility before and after exercise. To measure proprioceptive sensation, the angles were measured at both shoulder joints, elbow joints, hip joints, and knee joints using the active joint sensory position test method. To measure flexibility, situp forward bending evaluation was performed. Results: In the FEG, bilateral proprioceptive sensation and flexibility improved significantly after intervention (all P<.01). There were no significant differences in the CG (all P>.05). After the intervention, there were significant differences between the groups in both proprioceptive sensation and flexibility (all P<.05). Conclusion: The findings suggest that exercise using FMS can significantly improve proprioceptive sensation and flexibility. Therefore, it is suggested to consider exercise using FMS as an intervention to increase joint proprioceptive sensation and flexibility.

        Background: The weakness of the gluteus medius (GM) is associated with various musculoskeletal disorders. The increasing GM activity without synergistic dominance should be considered when prescribing pelvic drop exercise (PD). Isometric hip extension or flexion of the non-weight bearing leg using thera-band at the ankle during PD may influence hip abductor activities. Objects: To determine how isometric hip extension or flexion of the non-weight bearing leg using thera-band at the ankle during PD influences the activities of three subdivisions of GM (anterior, GMa; middle, GMm; posterior, GMp), tensor fasciae latae (TFL), contralateral quadratus lumborum (QL), and GMp/TFL, GMm/QL activity ratios in patients with GM weakness. Methods: Twenty-three patients with GM weakness were recruited. Three types of PD were performed: PD, PD with an isometric hip extension of the non-weight bearing leg (PDE), and PD with an isometric hip flexion of the non-weight bearing leg (PDF). Surface electromyography (SEMG) was used to measure hip abductor activities. One-way repeated-measures analysis of variance was used to assess the statistical significance of muscle activities and muscle activity ratios. Results: GMa, GMm, and GMp activities were significantly greater during PDF than during PD and PDE (p < 0.001, p = 0.001; p = 0.001, p = 0.005; p = 0.004, p = 0.004; respectively). TFL activity was significantly greater during PDE than during PD and PDF (p < 0.001, p < 0.001, respectively). QL activity was significantly greater during PDF than during PD (p = 0.003). GMp/TFL activity ratio was significantly lower during PDE than during PD and PDF (p = 0.001, p = 0.001, respectively). There were no significant differences in the GMm/QL activity ratio. Conclusion: PDF may be an effective exercise to increase the activities of all three GM subdivisions while minimizing the TFL activity in patients with GM weakness.

        Background: Clinical practice guidelines for patients with chronic low back pain (CLBP) recommend therapeutic exercise, and recently, interventions for pain neuroscience education (PNE) are also recommended. Objectives: To investigate the effects of aquatic exercise combined with PNE on pain, disability, and fear-avoidance beliefs in patients with CLBP. Design: Randomized control trial. Methods: The 27 participants recruited in this study were randomly allocated as pain neuroscience education combined with aquatic exercise group (PAEG, n=14) and aquatic exercise group (AEG, n=13). Both groups performed aquatic exercise for 50 minutes, 3 times a week for 6 weeks, and only PAEG received additional PNE. Numeric pain rating scale (NPRS), modified oswestry disability questionnaire (MODQ), and fear-avoidance beliefs questionnaire (FABQ) were used as evaluation methods before and after intervention. Results: Statistically significant decrease in NPRS, MODQ and FABQ (physical activity and work score) before and after intervention in PAEG. However, there were statistically significant changes in NPRS, MODQ and FABQ (physical activity score) before and after intervention in AEG. PAEG and AEG before and after intervention indicated statistically significant differences in MODQ and FABQ (work score). Conclusion: Aquatic exercise combined with PNE improved disability (MODQ) and fear-avoidance beliefs (FABQ) has been shown to have additional benefits. Therefore, combining PNE as a clinical intervention for CLBP patients will enhance the therapeutic effect.

        Background: Changes in foot sole shape can result in plantar muscle weakness, lack of proprioception, increased ankle instability, and an inability to balance. Objectives: To investigated whether different floor surfaces influenced the effect that short-foot exercises have on the foot core system of healthy individuals. Design: Pretest-posttest control group experimental design. Methods: This exercise shortens the length of the foot by raising the medial longitudinal arch, strengthening the intrinsic muscle of the sole, and maintaining the shape of the medial longitudinal arch. Results: There was a significant difference in the angle of the medial longitudinal arch in the mat exercise group (MEG) and vibration exercise group (VEG) before and after the intervention (P<.05). As the arch angle decreased, the arch height increased. Post hoc analysis showed that there was no difference between the floor exercise group (FEG) and MEG or between the MEG and VEG (P>.05). In terms of the weight distribution index (WDI, there was a significant difference in the MEG and VEG (P<.05) but not in the FEG before and after the intervention (P>.05). The post hoc analysis results showed that there was no difference between the FEG and MEG (P>.05). Conclusion: Various methods to improve the strength of intrinsic muscles of the sole are more effective than no stimulation, and that short-foot exercise combined with sensory stimulation can be recommended for maintaining and increasing the medial longitudinal arch.

        계약외채무의 준거법에 관한 유럽연합 규정(로마Ⅱ) 제18조는 직접청구권을 계약외채무의 준거법과 보험계약의 준거법에 선택적으로 연결함으로써 법원이 직권으로 피해자에게 유리한 법을 선택하도록 정하고 있고, 유럽사법재판소는 위 조항의 해석에 관하여 피해자는 보험계약 당사자들이 보험계약에 적용될 법으로 선택한 준거법의 조항과는 상관없이, 계약외채무의 준거법이 허용하는 한 보험자를 상대로 직접청구를 할 수 있다고 판시하였다. 또한 브렉시트 이후 로 마Ⅱ는 Retained EU-law로서, 로마Ⅱ 제18조에 관한 유럽사법재판소의 판시는 Retained EU case-law로서 각각 영국에서 그 효력이 유지된다. 한편 영국 대법원은 Fanti 및 Padre Island 사건에서 피해자가 보험계약자보 다 더 나은 지위에 설 수는 없다는 기본적인 원칙을 선언하면서 선지급 원칙의 유효성을 밝힌 바 있고, 이후 영국의 하급심 판결들 또한 로마Ⅱ 제18조의 규정 취지 및 그에 관한 유럽사법재판소의 판시와는 달리 피해자 또한 보험자와 피 보험자가 보험계약에서 정한 관할합의 조항에 구속된다는 점을 근거로 하여 피 해자가 다른 국가에서 보험자를 상대로 직접청구권을 행사하는 것을 용인하지 않았다. 그러나 영국 대법원의 Fanti 및 Padre Island 사건은 로마Ⅱ 시행 이전 의 것일 뿐만 아니라 유럽사법재판소는 로마Ⅱ 시행 이후 제18조의 성격에 관 하여 명확하게 판시하였고 그 효력이 여전히 영국에 대하여도 유지되고 있다. 아울러 소위 Brussels I 규정, 위 규정을 적용한 유럽사법재판소의 판시가 더 이상 영국에 대하여 효력이 없는 현재 상황에서는 보험계약에서 정한 배타적 관할합의 조항(가령 영국 법원)이 우선시될 가능성이 높지만, 영국이 추후 Brussels I 규정과 실질적으로 내용이 동일한 2007 Lugano Convention에 가입한 다면 Brussels I 규정에 근거하였던 유럽사법재판소의 판시 취지는 다시 중요하 게 고려될 수 있다. 결국 대한민국 법원에 피해자가 보험자를 상대로 직접청구권을 행사하는 소 가 제기되고, 보험자와 피보험자 사이의 해상책임보험계약에서 영국의 법률과 관습을 준거법으로 정하고 있는 경우에도, 로마Ⅱ(Retained EU-law) 제18조의 규정 및 유럽사법재판소의 판시(Retained EU case-law) 취지대로 불법행위지의 준거법에도 선택적 연결을 허용함으로써 피해자가 두텁게 보호될 수 있도록 관 련 해석이 이루어져야 한다.

        Background: Generally, rounded shoulders may occur when an individual habitually takes a relaxed, slouched posture. Although various studies on the round shoulder exist, studies on the effect of improvement of thoracic mobilization on the round shoulder are insufficient. Objectives: To investigate the effect of thoracic mobilization on round shoulders and pulmonary capacities. Design: Randomized controlled trials. Methods: Twenty subjects were randomly allocated into an exercise group (n=10) and a mobilization group (n=10). To quantify the round shoulder before and after the intervention, the distance between the acromion and the table surface was measured, and the pulmonary capacities were also measured. The intervention program was conducted twice a week for 6 weeks. The exercise group performed corrective exercise, and the mobilization group performed both corrective exercise and thoracic mobilization. Results: The round shoulder in both groups was significantly decreased (P<.05), and the pulmonary capacities were significantly improved (P<.05). However, there was no significant difference between the two groups (P>.05). Conclusion: The combination of corrective exercise with stretching and strengthening exercises led to the improvement of round shoulders and pulmonary capacities, no additional benefits were detected with thoracic mobilization.

        Background: The purpose of this study was to investigate whether the function of stroke patients could be improved by simultaneously performing bridging and masticating exercises. And, this was tested by examining whether the effects of arousal and cognitive improvement due to mastication muscle activity could affect exercise ability. Objectives: To compare the effects, the movement of the center of pressure and the stability limit change were measured using a balance analysis platform (BT4). Design: Randomized controlled trial. Methods: In this study, 36 chronic stroke patients were randomly assigned to either single training group of the bridging exercise or combined training group that performed both the bridging exercise and the mastication exercise. The exercise was performed for thirty minutes a day, three times a week, for eight weeks. Results: In both groups, the static balance ability improved after exercise, but the dual-task training group had a better improving effect on the distance and area of the center of pressure while the eyes was open. The dynamic balance ability also improved after exercise, and the dual-task training was more effective in reducing forward, left, and right movements, but not in backward movement. Conclusion: The importance of mastication was recognized in the rehabilitation of chronic stroke patients, and it can be expected to use mastication to improve balance in stroke patients in the future.

        Background: Shoulder external rotation exercises are commonly used to improve the stabilizing ability of the infraspinatus. However, during exercise, excessive activation of the posterior deltoid compared to the infraspinatus causes the humeral head to move anteriorly in an abnormal position. Many researchers have emphasized selective activation of the infraspinatus during shoulder external rotation exercise. Objects: This study aims to delineate the optimal exercise method for selective activation of infraspinatus by investigating the muscle activities of the infraspinatus and posterior deltoid according to the four shoulder exercise methods and two forearm positions. Methods: Thirty healthy individuals participated in this study. The participants were instructed to perform shoulder external rotation exercises following four exercise methods: sitting external rotation (SIER); standing external rotation at 90° abduction (STER); prone external rotation at 90° abduction (PRER); side-lying external rotation (SLER), and two forearm positions (neutral, supinated). The electromyography (EMG) signal amplitude was measured during each exercise. Surface EMG signals were recorded from the posterior deltoid, infraspinatus, and biceps brachii. Results: EMG results of the infraspinatus and posterior deltoid in PRER, were significantly higher than that of the other exercises (p < 0.01). The EMG ratio (infraspinatus/posterior deltoid) in SIER was significantly higher than that of the other exercises. EMG activation of the posterior deltoid in SIER, PRER, and SLER was significantly higher in neutral than in supinated (p < 0.01). Furthermore, the EMG of the infraspinatus in SIER was significantly higher in neutral than in supinated (p < 0.01). The EMG ratio (infraspinatus/ posterior deltoid) in SIER was significantly higher in neutral than in supinated (p < 0.05.) Contrarily EMG ratios in PRER and SLER were significantly higher in supinated than in neutral (p < 0.05).

        In accordance with the Enforcement Decree of the Act on Physical Protection and Radiological Emergency, operators of Nuclear Power Plants (NPP)s must conduct full cyber security exercise once a year and partial exercise at least once every half year. Nuclear operators need to conduct exercise on systems with high attack attractiveness in order to respond to the unauthorized removal of nuclear or other radioactive material and sabotage of nuclear facilities. Nuclear facilities identify digital assets that perform SSEP (Safety, Security, and Emergency Preparedness) functions as CDA (Critical Digital Assets), and nuclear operators select exercise target systems from the CDA list and perform the exercise. However, digital assets that have an indirect impact (providing access, support, and protection) from cyber attacks are also identified as CDAs, and these CDAs are relatively less attractive to attack. Therefore, guidelines are needed to select the exercise target system in the case of unauthorized removal of nuclear or other radioactive material and sabotage response exercise. In the case of unauthorized removal of nuclear or other radioactive material, these situations cannot occur with cyber attacks and external factors such as terrorists must be taken into consideration. Therefore, it is necessary to identify the list of CDAs that terrorists can use for cyber attacks among CDAs located in the path of stealing and transporting nuclear material and conduct intensive exercise on these CDAs. A typical example is a security system that can delay detection when terrorists attack facilities. In the case of sabotage exercise, a safety-related system that causes an initiating event by a cyber attack or failure to mitigate an accident in a DBA (Design Basis Accident) situation should be selected as an exercise target. It is difficult for sabotage to occur through a single cyber attack because a nuclear facility has several safety concepts such as redundancy, diversity. Therefore, it can be considered to select an exercise target system under the premise of not only a cyber attack but also a physical attack. In the case of NPPs, it is assumed that LOOP (Loss of Offsite Power) has occurred, and CDA relationships to accident mitigation can be selected as an exercise target. Through exercise on the CDA, which is more associated with unauthorized removal of nuclear or other radioactive material and sabotage of nuclear facilities, it is expected to review the continuity plan and check systematic response capabilities in emergencies caused by cyber attacks.

        본 연구의 목적은 정적 플랭크 운동의 동작 차이에 따른 코어근육의 근활성도를 비교하는 것이 었다. 본 연구의 대상자는 “J”대학교 20대 남성 10명을 대상으로 진행하였고(연령, 23.20±0.65 세; 신장, 174.54±1.51 cm; 체중, 70.00±2.24 kg; 신체질량지수, 22.94±0.51 kg/m2), 4가지의 풀, 엘보우, 사이드 및 리버스 정적 플랭크 동작을 수행하였으며, 근전도 분석을 위한 표면전극 부착 부위는 신체 근육의 우측 복직근, 외복사근, 광배근 및 척추기립근으로 설정하였다. 본 실험 결과, 광배근과 척추기립근의 근활성도 는 리버스 플랭크 동작 시 가장 높게 나타났고(p<.001), 복직근과 외복사근의 근활성도는 엘보우 플랭크 동작 시 가장 높게 나타났다(p<.001). 따라서 본 연구의 결과는 추후 정적 플랭크 동작 시 효과적인 운동 프로그램의 자료가 될 것으로 기대된다.
