Background: The flexible flatfoot is characterized by a flattening of the foot arch due to excessive bodyweight. The use of shoe insoles or taping methods has been identified as effective in realigning the navicular or calcaneus bones and addressing supination in pronated feet. Objects: This study aimed to analyze the difference between the arch taping attachment method, introduced in a previous study, and a novel taping method designed to provide support to the inner aspect of the heel bone in cases of flexible flatfoot. Methods: A navicular drop test was performed to discriminate flexible flatfoot. To analyze the differences in pressure distribution during walking for each taping method, the subjects underwent testing in the barefoot state with no attachments. The procedure included a sequence of arch taping and heel taping. Subsequent analysis of pressure distribution during walking utilized the GaitRite® system (GAITRite Gold, CIR Systems Inc.). Results: Arch taping and calcaneus taping significantly reduced the integrated pressure over time and peak pressure on the medial side of the midfoot for both feet compared to the barefoot state. Conclusion: The findings of this study suggest that supporting the inside of the heel through calcaneus taping, without direct stimulation to the longitudinal arch and navicular bone, is an effective intervention for flexible flatfoot.

Background: Ankle sprains occur frequently among humans who undertake various body movements. Diverse walking environments and dual tasks, that can affect ankle sprains, have been studied. However, there is a lack of research on inter-trial variability according to the changes in gait speed. Objects: The purpose of this study was to compare the adaptive ability of walking between the subjects with chronic ankle instability and healthy adults while performing a walking task with different walking speeds. Methods: In this study, 24 people in the chronic ankle instability group and 24 people in the healthy ankle group were selected as subjects. The length of the pre-measurement and the actual walking measurement were both set to 4.6 m. Once the subjects entered the measurement section, they changed their gait speed according to the randomly assigned speed change. Gait was measured twice and the average value was used for the analysis. Results: The coefficient of variation (CV) of cycle time in subjects with chronic ankle instability showed a significant difference in all cases except when the subjects changed their speed from preferred to slow and from slow to preferred. The CV of step length demonstrated a significant difference in all cases except for the change from slow to preferred and from preferred to fast. The cycle time and step length differential showed a significant difference only when the subjects changed the speed from slow to fast. Conclusion: The subjects with chronic ankle instability were found to have significantly reduced walking adaptability while performing inter-trial variability tasks with different gait speeds compared to healthy subjects.

Background: It is well known that squat exercises are good for scoliosis patients. Especially wall facing squat (WS) is believed to be more effective than normal squat (NS). Objectives: In order to find out what effect the wall squat has on the rehabilitation exercise of patients with lumbar scoliosis compared to the conventional squat, the force between the lumbar segments was compared using a motion analysis system. Design: Quasi-experimental study. Methods: In this work, an attempt was made to provide a scientific basis for these experiences. Inverse dynamics simulations were performed for each of the 10 subjects with mild scoliosis during NS and WS using subject-specific 3D musculoskeletal models. Exercises with three sets of five cycle for NS or WS were performed. Muscle forces calculated from the simulations were compared with electromyography data for verification. Results: The imbalance of muscle forces between the right and left in erector spinae (ES) decreased with the progress of WS sets. The difference of 14.1% for the 1st set diminished to 1.8% during the 3rd set. Conclusion: The overall level of right and left ES muscle forces also increased from the 1st set to the 3rd set. The results of simulations indicated that WS was more effective than NS for scoliosis correction.

Background: The gluteus maximus (GM) muscle comprise the lumbo-pelvic complex and is an important stabilizing muscle during leg extension. In patients with low back pain (LBP) with weakness of the GM, spine leads to compensatory muscle activities such as instantaneous increase of the erector spinae (ES) muscle activity. Four-point kneeling arm and leg lift (FKALL) is most common types of lumbopelvic and GM muscles strengthening exercise. We assumed that altered hip position during FKALL may increase thoraco-lumbar stabilizer like GM activity more effectively method. Objects: The purpose of this study was investigated that effects of the three exercise postures on the right-sided GM, internal oblique (IO), external oblique (EO), and multifidus (MF) muscle activities and pelvic kinematic during FKALL. Methods: Twenty eight healthy individuals participated in this study. The exercises were performed three conditions of FKALL (pure FKALL, FKALL with 120° hip flexion of the supporting leg, FKALL with 30° hip abduction of the lifted leg). Participants performed FKALL exercises three times each condition, and motion sensor used to measure pelvic tilt and rotation angle. Results: This study demonstrated that no significant change in pelvic angle during hip movement in the FKALL (p > 0.05). However, the MF and GM muscle activities in FKALL with hip flexion and hip abduction is greater than pure FKALL position (p < 0.001). Conclusion: Our finding suggests that change the posture of the hip joint to facilitate GM muscle activation during trunk stabilization exercises such as the FKALL.

Background: People these days use smartphone extensively as a means of diverse social activities, but excessive use of it has also created increasing forward head posture (FHP) with neck pain. To improve this FHP, neck stabilization exercise is necessary. Objectives: This study was to investigate the effects of stabilization exercise using biofeedback on FHP subjects with neck pain. Design: A non-randomized, controlled intervention study. Methods: This study chose 18 college students in their 20s whose neck disability index (NDI) was equal to or higher than 10 and cranio-vertebral angle indicated FHP as experimental group. The control group selected 18 persons with no neck pain and a normal range of cranio-vertebral angle. The stabilization movement was performed by applying three phases of pressure, with low of 20 mmHg, intermediate of 25 mmHg, and high of 30 mmHg, using the Stabilizer. To check the effects of stabilization exercise according to pressure, the circumference of deep neck muscles was measured with ultrasonic waves, and the activity of surface muscle of sternocleidomastoid (SCM) was measured using electromyography (EMG). Results: When the circumference of the deep neck flexor was analyzed according to the pressure change during stabilization exercise, the experimental group showed increase at all pressures. The activity of the SCM of the surface muscle increased in both groups as the pressure increased. Conclusion: The application of stabilization exercise was found to be more effective on forward head posture subjects with neck pain at lower pressures.

Background: Posterior capsule tightness (PCT), commonly seen in overhead athletes, is a soft tissue adaptation that is also noted in non-throwers. PCT is associated with scapular and humeral kinematic alterations, significant restriction of shoulder internal rotation (IR) range of motion (ROM), and significant scapular anterior tilting. Sleeper and cross-body stretches (CBS) are suggested for PCT and IR deficits, and have been modified since introduction. A novel modified sleeper stretch (NMSS) was designed in this study to prevent the risk of anterior translation of the humeral head. Though the effects of posterior shoulder stretching exercise have been widely studies, to the best of our knowledge, no previous studies have investigated the effectiveness of posterior shoulder exercises in decreasing scapular anterior tilting. Objects: To compare the immediate effects of two posterior shoulder stretching exercises (NMSS and CBS) on scapular anterior tilting and shoulder IR ROM. Methods: Thirty-two subjects with anteriorly tilted scapula and IR deficits [mean age: 24.3 ± 2.5 years; 15 males and 17 females] participated in this study. Subjects were randomly assigned to either the NMSS or CBS groups. Scapular anterior tilting (at rest and at shoulder 60° active IR) and shoulder IR ROM were measured before and immediately after intervention. Results: Scapular anterior tilting significantly decreased, while the shoulder IR ROM significantly increased in both groups. However, there was no significant group-by-time interaction effect or significant difference between the groups. Conclusion: Both stretching exercises were effective in restoring shoulder IR ROM and decreasing scapular anterior tilting.

우리나라의 산업안전보건교육은 일반근로자, 사업주, 근로감독관 등을 대상으로 하나, 체계적이지 못하고 산발적으로 이루어지고 있다. 특히, 청 소년들을 위한 산업안전보건육은 법적 근거가 명확하지 않고, 담당기관, 프로그램 등 체계적이지 못하다는 비판이 제기되고 있다. 최근 한국고용 노동교육원이「한국고용노동교육원법」 제3조에 따라 전국 중·고등학생 및 청소년을 대상으로 노동인권교육을 실시한다고 발표하였으나, 주로 일반 적인 노동교육에 집중된 측면이 있어, 산업안전보건교육의 필요성이 제기 된다. 오늘날 산업재해로 인한 사망사고 등이 지속적으로 발생함에 따라 산업재해를 예방하고, 건강하고 안전한 근무환경을 조성하기 위해 산업안 전보건교육이 더욱 중요한 과제가 되었다. 특히, 청소년들은 일을 처음으 로 하거나 시작하기 전, 사업장의 안전보건과 생산적 효율성을 위해 기본 지식, 기술 및 능력을 갖출 필요가 있다. 미국은 우리나라와 달리 산업안 전보건교육의 대상을 분리하여 대상자별로 법적 근거를 달리 규율하고, 담당기관, 교육내용, 교육수준 등을 차별화하여 교육하고 있다. 이에 본 논문은 미국 산업안전보건교육의 법·정책적 제도로부터 도출할 수 있는 시사점을 알아보고자 한다. 첫째, 산업안전교육에 관한 공공부문 은 모범적 사용자 역할로서 근로자 등에게 교육을 제공하고 있으며, 교육 을 강화하고 있다. 둘째, 미국은 산업안전보건교육에 관한 법체계의 정합 성을 확립하고 있다. 산업안전보건교육 관련 「산업안전보건법」,「연방시행 규칙」,「훈련지침」을 마련함으로써 법체계의 정합성을 확립하고 있다는 것 을 알 수 있다. 셋째, 미국은 산업안전보건교육의 근거가 되는 법률과 대 상을 분리하여 교육을 실시하고 있다. 넷째, 미국은 산업안전보건교육 관 련 컨소시엄을 구성하여 운영하고 있다. 이러한 시사점을 바탕으로 본 논 문은 청소년을 위한 산업안전교육을 실시하기 위해서는 「청소년 기본법」 을 근거로 담당기관을 설립 또는 지정하여 교육수준별 전문성을 확보하여 야 하고, 업종별로 필요한 교육훈련과 기준을 상세하게 기술하고 이와 관 련된 과목들을 사업장 또는 사업장 외 훈련장에서 이수할 수 있도록 교육 편제를 변경하는 것도 고려해 볼 만 하다.

Background: For the elderly, masticatory function is one of the most important oral functions and the masticatory ability is related to the wearing of dentures. Many older people wear dentures for their masticatory function, but a significant number of older people who use dentures have found that they feel uncomfortable when performing their daily activities, such as performing masticating functions or talking. Objects: The purpose of this study is to investigate how the forward head posture (FHP), respiratory function and thickness of masseter (MS), and sternocleidomastoid (SCM) are affected by the presence or absence of dentures in the elderly, and what kind of correlation there is between these variables. Methods: The study was conducted on 11 patients in the normal group and 13 in the denture group. The participant’s cognitive ability was evaluated using Mini-Mental State Examination Korean (MMSE-K), and the FHP was evaluated by measuring the craniovertebral angle (CVA). The thickness of the MS and SCM muscles were measured using ultrasound, and respiration was measured with a spirometry. As for the statistical method, the correlation of each variable was investigated using Spearman’s correlation coefficient. Results: In the normal group, there was a significant correlation between forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) (p < 0.001), and in the denture group, FVC and FEV1 (p < 0.001), maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) (p < 0.001), CVA and Lt. MS (p = 0.012). Conclusion: CVA and Lt. MS of the denture group have a high negative correlation, it is related that the thickness of MS may be thick when the elderly wearing dentures are FHP.

Background: The craniocervical flexion test (CCFT) was developed for the activation and endurance of deep cervical flexors. However, the muscle thickness and muscle thickness changing ratio of the sternocleidomastoid (SCM) and deep cervical flexor (DCF) muscles in subjects with and without forward head posture (FHP) have not been reported. Objects: To determine the difference in thickness of the SCM and DCF muscles and the difference in the muscle thickness changing ratio between SCM, DCF, and DCF/SCM 20 mmHg and DCF/SCM 30 mmHg between subjects with and without FHP. Methods: Thirty subjects with and without FHP were enrolled. The muscle thickness of the SCM and DCF was measured when maintained at a baseline pressure of 20 mmHg and a maximum pressure of 30 mmHg using a pressure biofeedback unit during the CCFT. Ultrasonography was used to capture images of SCM and DCF muscle thickness during the CCFT, which was calculated using the picture archiving and communication system (PACS). Results: We observed a significant difference within the pressure main effect between SCM and DCF at a baseline pressure of 20 mmHg and a maximum pressure of 30 mmHg (p < 0.05). However, there was no significant difference in the muscle thickness and muscle thickness changing ratio for SCM and DCF during CCFT between subjects with and without FHP. Conclusion: There was no significant difference in the muscle thickness recruitment pattern during CCFT in posture changes between subjects with and without FHP.

Background: Low back pain (LBP) is a representative disease, and LBP is characterized by muscle dysfunction that provides stability to the lumbar spine. This causes physical functional problems such as decreased posture control ability by reducing the muscular endurance and balance of the lumbar spine. Pelvic compression using instruments, which has been used during recent stabilization exercises, focuses on the anterior superior iliac spine of the pelvis and puts pressure on the sacroiliac joint during exercise, making the pelvis more symmetrical and stable. Currently, research has been actively conducted on the use of pelvic compression belts and non-elastic pelvic belts; however, few studies have conducted research on the application effect of pelvic compression using instruments. Objects: This study aimed to investigate whether there is a difference in trunk muscular endurance and dynamic and static balance ability levels by applying pelvic stabilization through a pelvic compression device between the LBP group and the non-LBP group. Methods: Thirty-nine subjects currently enrolled in Daejeon University were divided into 20 subjects with LBP group and 19 subjects without LBP (NLBP group), and the groups were compared with and without pelvic compression. The trunk muscular endurance test was performed with 4 movements, the dynamic balance test was performed using a Y-balance test, and the static balance test was performed using a Wii balance board. Results: There was a significant difference the LBP group and the NLBP group after pelvic compression was applied to all tests (p < 0.05). In the static and dynamic balance ability test after pelvic compression was applied, there was a significant difference in the LBP group than in the NLBP group (p < 0.05). Conclusion: These results show that pelvic compression using instruments has a positive effect on both those with and without LBP and that it has a greater impact on balance ability when applied to those with LBP.

이 글에서는 현재 우리 사회에서 공정함과 관련해 많은 비판이 가해지고 있 는 위선과 기만이라는 태도를 검토한다. 그러나 이때의 비판은 개인마다 상이한 기준과 수준에 따라 이루어지는 것으로 보인다. 이 명명은 사실 특정한 행위와 모습에 대한 인식, 판단과 평가를 거쳐 일어나기 때문이다. 특히 공정함을 해쳤 다고 평가되는 위선자는 어쩌다 타인을 속이게 된 이가 아니라, 의도를 지니고 공정함을 가장하는 인물로 비난받게 된다. 따라서 실제 위선과 기만은 그 자체 가 독립적인 대상으로 실재한다기보다는 사회구성원 각자의 인식, 판단과 평가 가 집합되는 과정에서 발생한다고 말할 수 있다. 그런 점에서 이러한 위선과 기 만이라는 평가의 발생을 먼저 한 개인의 ‘고백’이라는 행위에서부터 살피려 한 다. 진정성 평가의 대상이 되는 고백 역시 단순히 개인의 양심이나 심정을 드러 내는 것이 아니라, 주체들이 자신들이 처한 상황을 특정하게 주지하는 한에서 이루어지기 때문이다. 그리고 미셸 푸코가 지적했던 것처럼 고백의 과정은 개인 주체들과 사회적 기준과 구조들이 관계를 맺는 과정이기도 하다. 결국 우리는 일괄적인 공정함을 논하지만, 이는 각 구성원들의 입장에 따라 서로 다른 기준 에서의 판단임을 직시하는 것이 필요하다. 이를 위해 고백의 형식으로 진술되는 성 아우구스티누스, 루소 및 근현대 소설 텍스트들을 확인한다. 이는 위선, 기만 과 관련하여 고백이라는 기제가 개인의 내면적 진정성 표출과 그에 관한 규범 화를 동시에 작동시키는 양상들을 함께 보여줄 것이다.

Background: Bird dog exercise (BDE) is one of the lumbar stabilization exercises that rehabilitate low back pain by co-contraction of the local and global muscles. Previous studies have reported the effect of various type of BDEs (for example, practicing the exercises on various surfaces and changing the limb movement) for muscle co-contraction. Objects: This study aimed to investigate the effect of knee joint flexion position of the raised lower limb on abdominal and back muscle activity during BDE in patients with chronic low back pain (CLBP). Methods: Thirteen males participated in this study (age: 32.54 ± 4.48 years, height: 177.38 ± 7.17 cm). Surface electromyographic (SEMG) data of the internal abdominal oblique (IO), external abdominal oblique (EO), lumbar multifidus (MF), and thoracic part of the iliocostalis lumborum (ICLT) were collected in two knee joint flexion positions (90° flexion versus 0° flexion) during BDE. The SEMG data were expressed as a percentage of root mean square mean values obtained in the maximal voluntary isometric contraction. Results: Greater muscle activity of the IO (p = 0.001), MF (p = 0.009), and ICLT (p = 0.021) of the raised lower limb side and the EO (p = 0.001) and MF (p = 0.009) of the contralateral side were demonstrated in the knee joint flexion position compared to the knee joint extension position. Greater local/global activity ratios of the abdominal muscle (i.e., IO and EO) of the raised lower limb (p = 0.002) and the back muscle (i.e., MF and ICLT) of the contralateral side (p = 0.028) were also noted in the knee joint flexion position. Conclusion: BDE with a knee joint flexion position might be recommended as an alternative lumbar stabilization exercise to enhance muscle activity in both the raised lower limb and the contralateral sides of the trunk for individuals with CLBP

본 연구에서는 학습자들의 VR에 대한 의식을 바탕으로 VR을 활용한 피부미용 교과목 개발을 위한 교육환경을 확보하고자, 총 105명의 학습자들의 VR에 대한 인식, VR의 체험요소, VR활용 피부미용 교과목 개발 인식, 일반적 특성에 관한 문항을 온라인 설문지를 이용하여 진행하였다. 빈도분석, 요인분석, 상관관계 분석을 통한 조사결과, VR에 대한 인지도가 높을수록 교육적 성과와 몰입도가 높을 것으로 (p<.01), 학력이 높을수록 VR 활용 피부미용 체험요소인 일탈성, 인지성, 관심도가 높은 것으로 나타났다 (p<.001). 상관관계에서는 VR이용 스킨케어 경험요인이 높을수록 VR 활용 피부미용 교과목 개발 인식이 높은 것으로 나타났다. 따라서 학습자의 기대와 4차 산업혁명 시대에 부합하는 VR을 활용한 피부미용 교 과목 개발과 교육이 빠르게 운영될 필요가 있음을 확인하였다. 이에 후속 연구에서는 VR 활용 피부미용 교과목 개발과 운영 후의 연구 진행이 필요할 것으로 사료된다.

Background: Individuals with scapular winging may have proprioceptive dysfunction which is important for motor control and causes shoulder instability. Reduced serratus anterior (SA) and lower trapezius (LT) muscle activity accompanied by over-active upper trapezius (UT), and pectoralis major (PM) may be contributing factors. Flexi-bar (FB) exercise may be used to increase joint position sense (JPS) and alter the target muscle activities. Objects: This study aimed to investigate the immediate effects of flexi-bar exercise prior to knee push-up plus (FPK) versus knee push-up plus (KPP) on JPS and muscle activity of SA, LT, UT, and PM in subjects with scapular winging. Methods: Eighteen subjects with scapular winging were recruited. JPS was investigated at baseline, after KPP and after FPK. Passive and active JPS errors were calculated by isokinetic equipment. Surface electromyography was used to record muscle activities during KPP and FPK. One-way repeated-measures analysis of variance and post hoc analyses were used to analyze the JPS error measured at baseline, after KPP and after FPK. Paired t-tests were used to compare muscle activities between KPP and FPK. Results: Passive JPS error was significantly decreased after KPP (p = 0.005) and after FPK (p = 0.003) compared to the baseline. Active JPS error was also significantly decreased after KPP (p = 0.016) and after FPK (p = 0.012) compared to the baseline. There was no significant difference in the passive and active JPS errors between KPP and FPK. SA activity during FPK was significantly increased (p = 0.024), and LT activity during FPK was significantly increased (p = 0.006). There were no significant differences in the UT and PM activity. Conclusion: FB might be recommended to immediately improve passive and active JPS and to selectively increase SA and LT muscle activities during KPP in individuals with scapular winging.

Background: Cervical spine mobilization is an effective intervention method to increase cervical range of motion (ROM). However, whether using a sling with cervical spine mobilization can provide a similar positive effect in improving ROM and muscle stiffness as conventional cervical spine mobilization has not yet been proven. Objectives: To investigated the effects of sling with cervical spine lateral mobilization on improving neck ROM and muscle stiffness in healthy subjects. Design: A two-group pre-posttest design. Methods: A total of 20 healthy subjects were allocated to a sling with cervical spine mobilization (SWCM) group (n=10) and a cervical spine mobilization (CM) group (n=10). The mobilization exercise at grade Ⅳ+ amplitude was applied to the left-side and right-side C3-C4 and C4-C5 of each group for three sets. The mobilization exercise was performed for 30 seconds (frequency of two vibrations per second), with a 30-second resting time. The active cervical ROM, muscle tone, and muscle stiffness of the cervical region of each group was measured and compared before and after the intervention. Results: The active cervical ROM of both groups significantly improved after the intervention (p<.05). However, no significant differences in the cervical active ROM, cervical muscle tone, and muscle stiffness were observed between two groups. Conclusion: The application of sling with cervical spine lateral mobilization is an intervention method that can be effectively used to improve the physiological movement of the neck, as well as cervical muscle tone and stiffness.
