This study investigated the effect of social support (MOS-SSS), and physical (ADL, IADL) and mental (CES-D, MMSE-K) function on the quality of life (WHOQOL- BREF) among the elderly at care facilities. The survey respondents were 524 elderly aged 65 and older living in 15 care facilities located in D city. Data were collected through a personal interview conducted by interviewers who visited each care facility from November 2015 to January 2016. As a result, the quality of life was significantly lower in the elderly group with lower social support, with dysfunction in ADL and IADL than in the normal range group, with depression and cognitive impairment group than in the normal range group. The quality of life had a significant positive correlation with social support, ADL, IADL and cognitive impairment, but a significant negative correlation with depression. According to the results of covariance structure analysis, physical function had a greater impact on the quality of life than mental function or social support. Lower quality of life was associated with lower physical and mental function and lower social support. Therefore, concrete measures need to be devised to enhance physical function in order to improve the quality of life among the elderly in care facilities.

This study is aimed to evaluate the effects of community-based prehabilitation program developed to prevent functional decline in the frail elderly and to provide a basis to practically operate this program in the public health care service. From March to August 2009, 110 frail elderly people were recruited among the registered participants of the home visit program in Korea to perform a prospective randomized community trial. We randomly assigned these people into two groups. One group (n=50) participated in the visiting prehabilitation program for 3 months focusing on improving their muscle strength of upper and lower limbs, walking ability, and balancing. The other group (n=60) underwent our visiting fall prevention program for control. To assess the effectiveness of prehabilitation program, physical functioning (PF) and short physical performance battery (SPPB) were measured for the primary outcomes and also some other indicators: exercise performance, nutritional status, emotional functioning, experience of admission, and events of fall. As a result, significant improvements of geriatric functional status were noticed among the participants. After 3 months, PF increased by 1.3 ± 3.8 points in prehabilitation group and decreased by 1.1 ± 5.4 points in controls (p=.020). SPPB improved by 2.4 ± 2.0 points in prehabilitation group and increased only 0.3 ± 1.5 points in controls (p<.001). Significant effects were also shown in their exercise performance tests and emotional status, the number of multiple falls, and the experience of functional decline after the fall (p .002-.038). Visiting prehabilitation program is safe and effective program for frail older adults. Thus, it is strongly recommended to universally adopt this program to prevent functional decline in the frail elderly.

This study was conducted to investigate the relationship between physical function (ADL, IADL) and mental function (depression, cognitive dysfunction) and quality of life in the elderly. The subjects of this study were 524 elderly people aged 65 or older who were admitted to 15 care facilities located in D metropolitan city. Data were collected through a personal interview conducted by interviewers that visited each care facility from November 2015 to January 2016. T-tests and ANOVA were used to compare the quality of life score for each independent variable, while multiple regression was used to determine the explanatory power of independent variables that affected quality of life. Quality of life was significantly lower among those of older age, lower educational level, living alone, with lower relationships with children, lower subjective health status, disability, lower ability for mastication, without regular eating habits, without regular exercise, and without regular health checkups. In addition, quality of life was significantly lower in the ADL and IADL, as well as among those with a higher depression level and lower cognitive impairment scores than their respective counterparts. The results of this study suggest that the quality of life among elderly that have been admitted to care facilities is significantly related to physical and mental functions as well as demographic characteristics, health status and health related behavioral characteristics.

인간의 사고 기능과 학습기능이 '뇌'를 바탕으로 이루어진다고 할 때, 뇌의 긴장을 풀어 원래의 건강하고 창조적인 이완 상태에서의 학습 상태가 유효하게 된다. 즉, 뇌파가 " $\alpha$" 상태 가 되었을 때 긴장된 신체의 각 부분이 충분히 이완되고 두뇌는 맑고 건강한 상태를 유지하여 활발하고 창조적인 상태가 된다. 뇌파의 측정 및 분석된 기존 연구에 의하면, 인간의 심리상태와 신체 상태, 행동 패턴에도 직, 간접적인 영향을 주어 뇌파의 조절이 인간 잠재능력 개발의 첩경이라는 결과가 보고되어진다. 이러한 관점에서 본 연구에서는 뇌의 특성을 고려하여 뇌를 이완시킴으로써 학생들의 학습능력을 향상시키 기 위한 새로운 접근 방법을 시도한다. 뇌파 조절이 가해지는 환경하에 학습 효율의 변화 정도를 정성적( 심리적, 학습적, 신체적) 및 정량적(영어 단어 암기력 TEST, 뇌파 특정 등)으로 평가 및 분석을 통해 뇌파 조절 효과가 학생들의 학습 효율을 더욱 향상 시킬 수 있는 지의 타당성을 검증하고 그 결과를 바탕으로 새로운 학습 방법을 모색하고자 한다. 한편, 본 연구에서는 실험 대상을 본 대학 임의의 2학년 학생 13 명 을 대상으로 하고 실험기간은 약 4개월에 걸쳐 실험 하였다. 뇌파 측정은 13명중 임의의 학생 7명을 선정 하여 각 40분씩 측정 분석하였다. 또한 영어 단어 암기력 TEST를 실시하여 그 결과를 뇌파 조절 전,후로 나누어 비교 분석하였다. 정성적 분석으로서 종합 설문지를 이용한 15 개 항목의 5점 척도를 사용하여 분석하였으며 가가 통계 이론을 이용하여 검증하였다. 뇌파 측정은 수행 전후 비교 결과 " .alpha. " 노출 비율이 수행 전보다 수행 후가 다소 높은 비유로 나타났으며, 특히 영어 단어 암기력은 평균적으로 크게 상승되는 것으로 나타났다. 정성적 분석 결과에서는 많은 심리적 변화 상태가 나타나고 있지만 전체적으로 마음의 안정감, 몸의 긴장 이완에 따른 건강 상태 유지, 수업 집중도 향상 등이 나타났다. 위와 같은 종합 적 분석 결과에 따라, 본 연구는 제조 현장의 생산성 향상 및 품질 향상과 연계하여 작업자의 작업 집중도 향상, 작업자의 육체적, 심리적 변화에 따른 생산성 및 품질 향상 변화 정도 등의 산업공학(인간공학) 제 분야의 여러 측면에서 연구 및 적용이 가능하리라 사료된다.

The aim of this study was to examine the quality of life (QOL) and its related factors in veterans with physical dysfunction. The survey data was collected from 412 patients with physical dysfunction managed at five veterans' hospitals in Seoul, Pusan, Daegu, Gwangju, and Daejeon city. The baseline for the quality of life was measured using the SF-36 (Short-Form 36), activities of daily living was measured using a Modified Barthel Index (MBI), pain level was determined using Quadruple Visual Analogue Scale (QVAS), and the depression level was assessed using Korean version of the Geriatric Depression Scale: Short-Form (SGDS-K). The SF-36 scores showed a significant correlation with age (r=-0.132), self-rated current health status (r=-0.545), active daily living (r=0.514), pain level (r=-0.243), and depression level (r=-0.565) (p<0.05). The most influential variables on the QOL were the depression level (B=-.969, p<0.001), QVAS (B=-0.163, p<0.001), and MBI (B=0.140, p<0.001). The results of this study showed that that depression, pain and activities of daily living are significant predictors of the QOL in veterans with a physical dysfunction. Therefore, healthcare providers need to consider these parameters for interventions to improve the QOL in veterans with a physical dysfunction.

In this study, we examined the impact on balance ability and jump performance of soccer players with functional ankle instability using virtual reality based neuromuscular posture control fusion training. Soccer players were divided into 15 people of virtual reality-based neuromuscular posture control fusion training group and 15 people of common treadmill training group and performed for 30 minutes three times a week for 8 weeks. In order to evaluate the balance of ability, using biorescue, it measured surface area, whole path length, limit of stability. In order to measure jump performance, it measured counter movement jump with arm swing and standing long jump. The results showed the statistically significant difference in the balance comparison of surface area, whole path length, limited of stability and the jump performance comparison of counter movement jump with arm swing, standing long jump. As a result, virtual reality-based neuromuscular posture control fusion training was found to be more effective to improve its balance ability and jump performance than common treadmill training.

Objective: This study aimed to examine the factors affecting bodily pain in women in their middle to older age who are caregivers of stroke patients. Methods: This study selected 75 stroke inpatients and 75 female caregivers in their middle to older age from five hospitals in Daegu and Gyeongbuk. Measurements included general characteristics, cognitive function, upper limb function, and activities of daily living of stroke patients, and general characteristics and bodily pain for the caregivers. We used stepwise multiple regression analysis to determine the factors affecting the bodily pain and Pearson's correlation analysis to confirm the correlation. Results: The factors affecting bodily pain in women in their middle to older age caregivers were the activities of daily living(${\beta}=-.489$, p<.001) and caregiver duration(${\beta}=-.309$, p=.003)($R^2=.276$). Correlation analysis showed that the activities of daily living, upper limb function, and cognitive function of stroke patients were significantly correlated (r=.434~.751, p<.001). Conclusions: The results of this study demonstrate that the functional level of stroke patients being cared for and the caregiver duration are important variables for reducing bodily pain in women in their middle to older age.

As people age and their physical functions are declined, they stay longer in the home, thus being more affected by the home environment. Many studies have shown the association between the home environment and health. However, little is known about the effect of the home environment on disability and depression of older people with functional limitation. This study, therefore, aimed to examine the moderating effect of the home environment on the pathway between walking limitation and instrumental activity of daily living(IADL) disability, and the relationship between IADL disability and depression. We performed logistic regression and multiple linear regression analyses with data on 3,027 participants from the 2018 Seoul Aging Survey. As results, first, older people who lived home with poor conditions showed a higher risk of walking limitation(OR=1.487, 95% CI: 1.250 - 1.770), IADL disability(OR=1.594, 95% CI: 1.303 - 1.949), and depression(OR=1.943, 95% CI: 1.553 - 2.430). Second, the home environment moderated the relationship between walking limitation and IADL disability. Older people with walking limitation who lived in poor housing condition experienced more IADL disability than others. Third, after controlling for walking limitation, the home environment had significant moderating effect on the relationship between IADL disability and depression. Elderly with IADL disability living in poor home experienced higher risk of depression. Based on these results, the study suggests the necessity of home modification intervention targeting functional limitation of older adults as strategy for preventing disability and depression, and enabling aging in place.
