목적 : 본 연구는 ADHD 성향의 대학생(이하, ADHD 성인) 3명을 대상으로 Dynavision을 이용하여 시지각과 집중력을 향상시키고자 하였다. 연구방법 : 이 연구는 A-B 개별실험연구를 통해 이루어졌다. 독립변인으로 Dynavision의 visual tracking, self-paced, apparatus-paced, digital flash 프로그램이 사용되었다. 중재는 적응기간(2회기)과 훈련기간으로 구성하였는데, 대상자 A의 훈련기간은 10회기, B와 C는 각각 7회기였다. 종속변인으로 중재 후의 시지각(MVPT-3, TVMS)과 집중력(스트룹, 100칸 계산문제)을 측정하였다. MVPT-3와 TVMS, 스트룹 검사는 중재 전과 후에 측정하였고, 100칸 계산문제는 매회기 측정하였다. 결과 : 중재 전, 후 대상자 모두 MVPT-3, TVMS 점수가 향상되었고 스트룹 검사의 수행 시간은 감소되었다. 또한, 회기 가 진행될수록 100칸 계산문제의 풀이속도가 증가하였고 오답수는 감소되었다. 결론 : 본 연구결과를 통해 ADHD 성인의 시지각과 집중력 향상에 Dynavision 훈련이 효과적임을 확인할 수 있었다. 향후에는 ADHD 아동이나 치매 노인을 대상으로 Dynavision을 인지에 적용한 연구들이 많이 이루어지길 기대해 본다.

Background: Whole body-electromyostimulation (WB-EMS) is widely used for the rehabilitation and recovery of patients with various neuromusculoskeletal disorders. Objects: To objectively measure changes in lower extremity and abdominal muscles after sit-to-stand dynamic movement training using WB-EMS. Methods: A total of 46 healthy adults (23 experimental and 23 control subjects) performed sit-to-stand exercise; the experimental group with WB-EMS, and the control group without WB-EMS. The muscle activity of the lower extremity, and the muscle thickness of the lower extremity and abdominal muscles were measured before and after the intervention. Results: In terms of electromyographic activity, there was a significant interaction effect for the rectus femoris (RF) muscle (F=30.212, p=.000). With regards to ultrasonographic imaging, the muscle thickness of the RF muscle had a significant interaction effect at the muscle contraction ratio (F=8.071, p=.007). The deep abdominal muscles, such as the transverse abdominal (TrA) and internal oblique (IO) muscles, also showed significant interaction effects at the muscle contraction ratio (F=5.474, p=.024, F=24.151, p=.000, respectively) Conclusion: These findings suggest that WB-EMS may help to improve the muscular activity of the RF muscle, and the muscle thickness of the RF muscle and deep muscles such as the TrA and IO muscles.

Background: The importance of postural stabilization and cervical mobilization in subjects with pain from the anterior head posture is drawing more attention. However, studies on head and neck stabilizing intervention after mobilization are lacking. Objective: To examine the effects of Kinesiotaping and posture setting exercise on forward head posture (FHP). Design: Crossover Study Design Methods: The subjects were 17 male and female college students in their 20s with FHP. They were randomized into the Kinesiology taping group (KTG) with 9 subjects and posture stabilizing exercise group (PSEG) with 8 subjects. The intervention was conducted for 4 weeks, and changes in pain, craniovertebral angle (CVA), and proprioception were observed before and after intervention. Results: Pain was significantly reduced in the KTG and PSEG both before and after intervention. CVA and proprioception were significantly increased only in the PSEG. The differences in CVA and proprioception between the two groups were significant. Conclusions: These findings suggest that the application of posture setting exercise could decrease pain, proprioceptive error and increase CVA on FHP

Background : There is lack of studies on the effects of the bag-carrying style on the shoulder muscles and body alignment in adults with rounded shoulder posture (RSP). Objective: The purpose of this study was to investigate the effects of various bag-carrying styles on muscle tone, muscle stiffness and spinal alignment in 20 adults with RSP as they were walking on a treadmill. Design : Crossover Study Design. Methods: A subject performed treadmill walking for 15 minutes at a speed of 4 ㎞/ｈ while carrying three different types of bags: a backpack, a cross bag, and a shoulder bag. Results : The results showed that the main effect of timing was observed in the muscle tone for all the variables and in muscle stiffness only for the upper and lower trapezius muscles. As for the main effect of timing, the muscle tone of the upper trapezius and the pectoralis major significantly increased in all conditions, while the muscle tone of the lower trapezius significantly decreased in all conditions. The muscle stiffness of the upper trapezius significantly increased in all conditions, while the muscle stiffness of the lower trapezius significantly decreased in all conditions. As for the spinal alignment, the dimple distance data values significantly decreased for the cross-bag style. Conclusions : This study demonstrated that walking with a heavy bag, regardless of the bag-carrying style, increased muscle stiffness around the shoulders in adults with rounded shoulder posture, and walking with a crossbag also induced changes in spinal alignment.

Background: It is difficult to assess whether community-dwelling frail older adults may remain pre-frail status or improve into a robust state without being directly checked by health care professionals. The health information perceived by older adults is considered to be one of best sources of potential concerns in older adult population. An online measurement system combined with item response theory (IRT) and computer adaptive testing (CAT) methods is likely to become a realistic approach to remotely monitor physical activity status of frail older adults. Objects: This article suggests an approach to provide a precise and efficient means of measuring physical activity levels of community-dwelling frail older adults. Methods: Article reviews were reviewed and summarized. Results: In comparison to the classical test theory (CTT), the IRT method is empirically aimed to focus on the psychometric properties of individual test items in lieu of the test as a whole. These properties allow creating a large item pool that can capture the broad range of physical activity levels. The CAT method administers test items by an algorithm that select items matched to the physical activity levels of the older adults. Conclusion: An online measurement system combined with these two methods would allow adequate physical activity measurement that may be useful to remotely monitor the activity level of community-dwelling frail older adults.

이 연구는 노년기 인지기능 및 생리적 건강상태와 관련 있는 정량화 뇌파의 Alpha 고유리듬 피크 위치 및 진폭의 출현 유무가 정신적⋅육체적 스트레스, 주의집중 등의 뇌파 지표들과 심박변이도 지표 간에 어떠한 관련성과 임상적 의미가 있는지 알아보고자 하였다. 이를 위하여 평균 73세 남녀 노인 76명을 대상으로 전두엽 2채널 뇌파와 1채널 심전도를 동시에 측정 가능한 장치를 이용하여 폐안시 EEG, HRV를 측정하였다. 의미있는 분석 결과는 다음과 같다. 첫 번째, Alpha 고유리듬피크 위치와 상관없이 고유리듬 진폭이 높게 잘 나타난 집단은 낮은 집단에 비해 정신적 스트레스에 대한 저항도는 높고, 육체적 스트레스는 낮게 나타나는 상관성을 보였다. 두 번째, 심박변이도의 HRV index, SDNN, RMSSD 지표는 집단 구분에 상관없이 공통적으로 서로 간 높은 양의 상관성을 보였다. 세 번째, Alpha 고유리듬 진폭이 잘 나타나지 않은 집단에서 좌․우뇌 Alpha 비대칭이 커질수록 육체적 스트레스를 반영하는 Delta/Alpha 비율과 주의집중 저하를 반영하는 Theta/SMR 비율도 커지는 상관성을 보였다. 네 번째, Alpha 고유리듬피크가 느린 리듬쪽에 위치한 집단은 빠른 리듬 쪽에 위치한 집단에 비해 Theta/SMR 비율이 높게 나타나 주의집중도 저하와 관련이 있음을 의미하였다. 따라서 정량화 뇌파의 Alpha 고유리듬 피크 위치 및 진폭의 출현 유무는 노년기 인지기능 및 생리적 건강상태를 반영하는 지표로 활용 가능성이 있음을 시사하였다.

This study employed the social comparison theory, brand signally theory and the theory of planned behaviour (TPB) to examine the extent to which attributes of a celebrity endorsing a brand and brand values impact on young adults’ cosmetics brand attitude and purchase intention. Data was collected from 301 young adult South Africans. Structural equation modelling results revealed that cosmetics brand attitude was influenced by celebrity attractiveness, credibility, celebrity product expertise and the symbolic brand value enjoyed from the brand. The brand attitude in turn predicted purchase intention.

Unlike slow fashion that takes workers, consumers and environmental welfare into consideration, fast fashion is criticized for neglecting these. This study investigates attitudes and adoption intention of the slow fashion concept among young adults in South Africa, a highly socio-economically unequal emerging market. An extended information adoption model will be adapted and tested through a self-administered survey of 300 respondents. The results will provide marketing professionals, environmental and consumer interest groups and policy makers with valuable insight into barriers and motivators of slow fashion idea adoption among young adults who are a large, influential and profitable consumer segment.

Background: Effect of cervical and lumbar tractions on the reduction in the angle of curvature and the effect of a correction exercise or a general traction method on balance, muscle strength, pain, and body alignment, however insufficient research has been undertaken on self traction exercises targeting patients with scoliosis. Purpose: To determine the effect of cervical and lumbar tractions on the reduction in the angle of curvature and the effect of a correction exercise or a general traction method on balance, muscle strength, pain, and body alignment. Design: Randomized controlled clinical trial (single blinded) Methods: Twelve adults(20s) with scoliosis were included in this study and performed a traction program that was composed of a 5-min warm-up exercise, a 15-min main exercise, and a 5-min cool-down exercise (25 minutes in total), three times a week for four weeks. The Chiro traction machine was used for the self-traction exercise. Vertebral alignment, muscle strength, and flexibility were compared before and after the intervention using the paired T-test. Results: The scoliosis angle, pelvic torsion, and lumbar extensor were significantly changed by intervention; however, there was no significant difference in flexibility. Conclusion: The results revealed that self-traction exercise activated blood flow through the extension and contraction of muscles, effectively increasing the function of the muscles around the vertebrae.

Background: Breathing is the essential step of Pilates exercise and can be used to activate core muscles. Although the effects of breathing exercise on pain, breathing muscles, and cervical posture have been extensively studied, little is known about the impact of Pilates breathing on spinal posture and alignment. Purpose: To determine the effect of 3D-Pilates breathing exercise on spinal curvature and alignment of healthy adults during corrected to normal alignment. Design: One group pre-post test design Methods: Eighteen participants were given a 3D-pilates breathing exercise twice a week (20 minutes per session) for three weeks and warmed up for 10 minutes before each exercise session. To examine spinal curvature and alignment of each subject, this study used radiation free rasterstereography (Formetric Ⅲ, Germany). Paired t-test and Wilcoxon signed rank test were performed to determine the difference between pre and post exercise. Results: There were statistically significant differences in height (p<.001), kyphosis angle (p<.05), trunk imbalance (p<.05), kyphotic apex (p<.01), cervical fleche (p<.05), pelvic tilt (p<.01), and lateral deviation (p<.05) between before and after 3D Pilates breathing exercise. However, there was no significant difference in lordosis angle. Conclusions: The study results indicated that three week 3D-pilates breathing exercise program could be presented as an effective rehabilitation method for improving spinal curvature and alignment.

Background: Functional ankle instability (FAI) indicating a decrease in muscle strength, proprioception, neuromuscular control, balance and postural control function. Objective: To investigate the effect of jumping exercise on the supporting surface on the ankle muscle thickness, proprioceptive sensation, and balance in adults with FAI. Design: Randomized Controlled Trial. Methods: Twenty young people with FAI were randomly assigned to the unstable supporting surface jump group (N=10) and the stable supporting surface jump group (N=10). The intervention was conducted three times a week for eight weeks, and for 30 minutes per session. Trampoline was used as an unstable support surface and the stable support surface was carried out on a regular floor. The thickness of the tibialis anterior muscle and medial gastrocnemius muscle was measured by ultrasonography, and the proprioception of dorsiflexion and plantarflexion was measured using an electrogoniometer. The dynamic balance was also measured with a balance meter. Results: The the muscle thickness of the medial gastrocnemius muscle was significantly higher in the stable supporting surface jump group than in the unstable supporting surface jump group (p<.05). Furthermore, the plantar flexion proprioception and dynamic balance were significantly improved in the unstable supporting surface jump group than in the stable supporting surface jump group in the intergroup comparison (p<.05). Conclusions: The conclusion has been reached in this study that the jumping exercise on the unstable supporting surface could be a more effective in improving FAI than the regular surface.

목적: 멀티포컬 소프트 콘택트렌즈가 시기능에 미치는 영향을 +1.00 D 안경렌즈를 이용한 저교정과 비교하고자 한다. 방법 : 17명의 대상군(평균 23.6±2.1세)이 본 연구에 참여하였다. 대상군의 구면 굴절 이상이 ±1.00 D 범위 이며, 난시가 –0.75 D 미만인 자로 선정하였다. 나안(NC), 근용 +1.00 D 처방의 멀티포컬 콘택트렌즈(CM), +1.00 D 안경렌즈를 사용한 저교정 (UL) 등 3가지 교정 방법에 대해 각각 반복 측정하였다. 원용 시력은 고대비 및 저대비 차트를 이용하여 측정하였으며, 원용 대비 민감도와 근용 시력을 측정하였다. 결과 : 시력 교정의 방법은 고대비와 저대비 차트를 이용한 원거리 시력에 유의한 영향을 끼치는 것으로 나타났으며 (p<0.01), 근거리 시력에는 시력 교정의 방법이 유의한 영향을 끼치지 않았으며 (p=0.34), 원거리 대비 민감도에는 유의한 영향을 끼치는 것으로 나타났다 (p=0.01). 결론 : 멀티포컬 콘택트렌즈는 최대 교정 시력과 대비 감도를 달라지게 하지 않았으며, 완전 교정 안경과 견줄 만한 전체적인 시각적 성능을 유지했다. 따라서, 중심부 근용 멀티포컬 콘택트렌즈는 시각적 성능이 저하될 수 있는 40대 이상과 같이 다른 연령대에 더 많이 처방될 수 있다.

우리나라 성인이 일상생활에 필요한 금융 지식을 충분히 지니고 있는지를 파악하기 위하여 KB금융공익재단이 2016년에 실시한 전 국민 경제 이해력 조사 자료를 활 용하였다. 우리나라 성인의 금융 지식 수준은 평균 66.2점이었다. 측정 문항별로 구분해서 살펴보면 이자율이 인상될 때 이득을 보는 사람을 옳게 구분하는 응답자 가 전체의 4분의 3이었으며, 임금이 소득에서 가장 큰 비중을 차지하고 있다는 사 실을 인지하고 있는 응답자는 84%에 이르렀다. 주식시장이 거래의 효율성을 제고 하는 역할을 한다는 시장의 기능을 이해하고 있는 응답자는 58%에 머물렀으며, 화 폐의 기능을 제대로 이해하고 있는 응답자는 절반에 미치지 못하였다. 개인의 금융 지식 점수를 기준으로 상위 집단과 하위 집단을 구분할 때, 남자, 40∼64세 성인, 서울/인천/경기 지역 거주자, 대학 재학 이상의 고학력자, 중간 이상의 소득자가 그 렇지 않은 사람보다 상위 집단에 해당할 가능성이 훨씬 높은 것으로 추정되었다. 반면에 경제교육 경험, 자신의 재산 상태에 대한 만족 정도 같은 요인은 상위 집단 에 해당할 가능성에 긍정적으로 기여하지 못했다. 금융 지식 수준이 전반적으로 만족스럽지 못하다는 평가 결과, 경제교육 경험이 금융 지식 수준 향상에 기여하지 못하고 있다는 추정 결과 등을 종합할 때 성인 대상 금융교육을 확대하되, 획일화 되고 천편일률적인 공급자 중심의 교육보다는 교육 대상자의 특성과 취약점을 고려 하는 맞춤형, 수요자 중심의 교육을 실시할 필요가 있음을 알 수 있다.

Background: Fall-related injuries in older adults are a major health problem, and the risks and mechanisms of these injuries should be affected by race, culture, living environment, and/or economic status. Objects: Research articles have been systematically reviewed to understand fall-related injuries in older adults in South Korea. Methods: 128 published research papers have been found through the Korea Citation Index and the Korean Studies Information Service System, and reviewed in various perspectives, including incidents, fall death rates, medical costs, causes, injury sites and types, locations where falls occurred, prevention strategies, scholarly fields interested in fall injuries, and the role of physical therapy. Results: Fall-related injuries were found to be more common in women than in men, and the number of incidents increased with age, with the highest rate found in individuals over 85 years old. Risk of fall injury was associated with education level, comorbidities, and fear of falling. Common places where falls occurred included the bathroom, living room, stairs, and hallway. Common types of injury included bruises, fractures, and sprains in the lower extremities. Intervention strategies included exercise programs, education, and protective clothing. Scholarly fields interested in fall-related injuries in older adults included medicine, nursing, physical therapy, occupational therapy, physical education, pharmacology, oriental medicine, biomedical engineering, design, clothing, and textiles. Physical therapy intervention using proprioceptive neuromuscular facilitation has been used to improve one’s balance. Conclusion: Any movement during the activities of daily living can lead to a fall. Physical therapists are highly educated to analyze human movements and should be involved in more research and practices to solve fall-related injuries in older adults.

Background: Improvement of the lumbo-pelvic stability can reduce the compensatory action of the erector spinae (ES) during prone hip extension (PHE). Furthermore, the application of abdominal drawing-in (ADI) maneuver increases the action of gluteus maximus (GM) and decreases the action of ES during PHE by improving the lumbo-pelvic stability. However, the post-ADI exercise effects on PHE, not the real-time application of ADI maneuver, has not been studied. Objects: This study is aimed at investigating the post-ADI exercise effects on the muscle activities of GM and ES during PHE. Methods: A total of 24 female adults participated in the study, and they were divided into two groups: Those with normal abdominal muscles (n1=12) and those with weak abdominal muscles (WA) (n2=12). Before the intervention, the subjects’ GM and ES muscle activities during PHE were measured. Subsequently, the two groups were asked to perform the ADI exercise for 10 minutes. After the ADI exercise, the GM and ES activities were equally measured during PHE. Results: The comparison result of the ES muscle activities before intervention shows a significant difference between the two groups (p<.05); the WA group showed higher muscle activities than the normal group. For the within-group comparison, the muscle activities of the ES in the WA group significantly decreased after the ADI exercise (p<.05). For the GM muscle activity, no significant difference was observed in all comparisons (p>.05). For the changes in muscle activities before and after the ADI exercise, a significant difference exists between the two groups only for the changes in ES activities (p<.05); WA group exhibits higher changes than the normal group. By contrast, no significant difference exists between the two groups for the changes in GM activities (p>.05). Conclusion: After the ADI exercise, the compensatory action of ES in the female adults with WC is implied to decrease during PHE.

이 연구의 목적은 복합운동이 노인여성의 낙상관련 지표 및 마이오카인에 미치는 효과를 보는데 있다. 근감소증은 근력의 손실로 인해 발생하고, 기능적 상태의 감소, 활동력의 저하에 따른 낙상의 위험성이 높아지고 끝내 사망의 위험성이 높아지게 된다. 유산소운동은 대근을 이용한 리듬과 반복적인 동작 으로 특징 지워지고 주로 유산소성 대사를 통한 산소를 에너지 이용으로 심폐체력, 체성분 및 심장과 호흡계 건강에 기여한다. 한편 저항운동은 근육에 스트레스를 가해 노인들의 근력관련 체력과 기능적 수행 개선에 기여한다. 근기능 및 심폐지구력 향상을 꾀하는 복합운동은 노년들의 효과적인 건강증진에 기여하는 것으로 나타내고 있다. 근육에서 분비되는 마이오카인은 운동에 중요한 요인으로 간주되고 있는데 지방세포 감소, 골격, 근육 및 인체 전반에 걸쳐 유익한 효과를 보인다.

To develop a empirical model for predicting the spring flight period of overwintering Ips acuminatus adult, their density were monitored in Korean pine (Pinus koraiensis) forests at Chuncheon in 2015. The monitoring data of the beetles and temperature in the forests were used to develop the empirical predictive model based on degree-day model, and it was validated using the data from Korean pine forest at Wonju in 2018. The lower threshold temperature for flight (LTF) and a thermal requirement for the onset of flight activity of the beetles in spring were estimated. As the result, the LTF was estimated as 1.3 ℃ and 269.96 DD was required for the spring flight. The median flight date estimated by the empirical model was one day earlier than the observed flight date. Therefore, the model is suitable for predicting the spring flight of overwintering I. acuminatus.
