This study was conducted to develop and evaluate the effectiveness of Multifactorial Fall Prevention Program (MFPP) for local low-income elderly people on physical·psychological, and home environmental hazards, and falling frequency. The selected elderly people was provided the MFPP during an eight-week period of time, once a week, 70 to 90 minutes per each section. The design of this study was non-equivalent control-group with repeated measuring by quasi-experimental study. Data were collected before treatment, 8 week after treatment and 4 week after retention from July to October, 2010. Data were analyzed with numbers, percentage, Fisher's exact test, x²-test, repeated measures ANOVA, ANCOVA and Logistic regression. There were significant differences in fall frequency, balance, fear of falling, fall efficacy, home environmental hazards between the experimental group (EG) and control group (CG). This study showed that the multifactorial fall prevention program(MFPP) was useful nursing intervention for strengthening physical·psychological and environmental functions of the low-income elderly people, as well as preventing fall.

This study recognizes it as a social problem that can be prevented by basic research on safety security design for the elderly, and aims to clearly analyze risk factors for injury. For this study, raw data from the 6th Korean National Health and Nutrition Survey were employed and analyzed. Their social characteristics were classified with standards including gender, education, EuroQoL(human locomotion, normal activity and pain uncomfortableness), the quality of life(PHQ-(1)(2)(4)), recognition on stress, activity restriction status and associated causes(bone fracture and joint injury). Their epidemiological traits were chronic diseases, 'diabetes and hip-joint pain', and health-behavioral traits were 'smoking, breakfast frequency and high-level physical activity status.' In conclusion, it can be found that damage risk of elderly rose in case of female, lower education, inconvenience or limitation, pain or discomfort in locomotion and daily activities, higher recognition of stress, lower interest in work, feeling of depression, despair, and weariness, restriction in activity caused by bone fracture and joint injury, having diabetes and hip-joint pain, smoking, low frequency in having breakfast and high-level physical activities. Based on this study, we envision that an effective solution for injury risk factors caused by the organic relation can be reached in the near future.

The obstructive factors of the smoothly running traffic are street improvement, major commercial buildings like department stores, the large markets, the stadiums, the concert buildings, a lot of steady cars for using parking lot. The accident of cost many lives and traffic congestion from these factors cause the result that it enables to pay the enormous expenditure socially and financially. For solving these problems, Japan adopts the Traffic Flagger System in 1972. This task has the effects of improving traffic flow in the traffic jam and mitigating risk of car accidents as leading pedestrians and vehicles thereby the task carries into effect in the area where the accident took place. Moreover, this security task is rapid growth after adopting and 59.6%(5,317) of the whole security company 8,924 in Japan based on December 2009 registered as the traffic leading security business. While South Korea is demanded of the measures about obstructive factors of the smoothly running traffic, it represents the limitation of the system and the safety management. Thus the current study suggests the we will analyze South Korea's actual condition and then discuss the law and education system for a realizable plan reached the public-Private cooperation for adopting Japan's Traffic Leading Security System.

Existing traffic safety studies have focused on identifying the relationship among roadway crashes, highway design and incremental weather condition such as rainy/ice weather. However, it is hard to find researches that studied the effect of sun glare on traffic safety although there are abundant evidences demonstrating that fatal traffic crashes are attributed to the sun glare. Affecting drivers'vision particularly during the morning or the evening time when the sun positions close to the horizon, sun glare directly deteriorate drivers'judgmental capability. In this paper, we numerically analyze the effect of sun glare on the drivers'vision in time and space domains. Applied to the roadways around St Louis area in the United States, the GIS based simulation analysis identifies the time of day in a year and the segments of highways that are potentially influenced by the sun glare. This study evidentially confirms the fact that roadway bounded for West and East directions have longer time influenced by sun glare particularly during Spring and Fall season than other roadways. The computational result provides risky time periods of day at intersections or pedestrian crossings where the sun glare potentially endangers traffic safety, which be utilized to reduce the crashes due to the sun glare.

This study was conducted to identify factors related to the musculoskeletal symptoms of 340 family caregivers who have a patient with brain damage based on self-administered questionnaires. The questionnaires included general characteristics, characteristics of care activities and caregivers' musculoskeletal symptoms. Data were collected from many long-term care hospitals and rehabilitation centers during March 17 to March 21, 2014. The results indicated that complaint rates of work-related musculoskeletal systems of the body sites differed. Factor analysis revealed that neck complaints were related to education (under mid), while shoulder complaints were related to sex (female), age (50-59), education (mid) and duration of care (< 2 years). Arm/elbow complaints were related to age (40-49), education (high) and duration of care (12-24). Complaints regarding the hand/wrist/finger were related to age (50-59) and duration of care (12-24), while those associated with the legs/feet were related to age (50-59) and duration of care (< 6[ED highlight - years? Please specify.]). Back problems were related to education (under mid, mid stage, high) and gait. The complaint rate regarding musculoskeletal symptoms during daily life was not statistically significant. Logistic regression analysis of significant factors related to subjective musculoskeletal symptoms identified ambulation and gait as having the greatest influence and complaint factor among family caregivers. The complaint rate of family caregivers differed among body parts. Being a caregiver for less than one year was found to have a significant impact on pain. Overall, long term family caregivers could be faced with risk factors for musculoskeletal problems, but there are many different factors that affect musculoskeletal symptoms with regards to their activities. Accordingly, comprehensive and systematic prevention plans for family caregivers who have patients with brain damage should be developed.

This study was understood the risk mechanism of falls in the elderly and reviewed previous research data to see if the principle of Pilates rehabilitation exercise could have a positive effect on balance ability and postural stabilization in the elderly, and the purpose of this study is to present literature-based data on the fall prevention effect of rehabilitation Pilates exercise. First, the rehabilitation Pilates exercise makes it available for strengthening the center of the body to stabilize the spine and pelvis and stimulates the nerve root, thereby having an effect on the balance and the joint stabilization. Second, a proprioceptive sensory impairment and a musculoskeletal degenerative disease due to aging increase the loss of balance ability and the instability in posture maintenance, thereby coming to raise the risk of a fall damage caused by the difficulty in performing motor functions and by the gait disturbance. Third, the rehabilitation Pilates exercise leads to improving the core muscle strength in older adults, resulting in being capable of expecting the betterment in the balance and the reaction time motor function. And there is a positive impact on the improvement in body imbalance and on the stability in movement involved in the fall prevention, resulting in being able to suggest the possibility of likely contributing to a reduction in a fall risk rate. In conclusion, the rehabilitation Pilates as the elderly exercise program showed effects on the improvement in the body's muscular strength, on the upgrade in a sense of balance, and on the stabilization of core. Thus, it was considered to diminish the risk factors for a fall damage caused by musculoskeletal degeneration and to be capable of preventing a serious disorder of activity due to a chronic senile disease.

Objective : The purpose of this study was to investigate biomechanical changes of the lower limb including dynamic stability with changes in illumination (300Lx, 150Lx, and 5Lx) and slope (level and $15^{\circ}$ downhill) as risk factors for elderly falls. Method : Fifteen elderly females were selected for this study. Seven infrared cameras (Proreflex MCU 240: Qualisys, Sweden) and an instrumented treadmill (Bertec, USA) surrounded by illumination regulators and lights to change the levels of illumination were used to collect the data. A One-Way ANOVA with repeated measures using SPSS 12.0 was used to analyze statistical differences by the changes in illumination and slope. Statistical significance was set at ${\alpha}=.05$. Results : No differences in the joint movement of the lower limbs were found with changes in illumination (p>.05). The maximum plantar flexion movement of the ankle joints appeared to be greater at 5Lx compared to 300Lx during slope gait (p<.05). Additionally, maximum extension movement of the hip joints appeared to be greater at 5Lx and 150Lx compared to 300Lx during slope gait (p<.05). The maximum COM-COP angular velocity (direction to medial side of the body) of dynamic stability appeared to be smaller at 150Lx and 300Lx compared to 5Lx during level gait (p<.05). The minimum COM-COP angular velocity (direction to lateral side to the body) of dynamic stability appeared smaller at 150Lx compared to 5Lx during level gait (p<.05). Conclusion : In conclusion, elderly people use a stabilization strategy that reduces walk speed and dynamic stability as darkness increases. Therefore, the changes in illumination during gait induce the changes in gait mechanics which may increase the levels of biomechanical risk in elderly falls.

Purpose: This study was a comparative analysis of stroke-related factors between recurrent patients and non-recurrent patients. Methods: A retrospective cohort study design was used, and data were collected from March 2020 to April 2020 using electronic medical records. 244 patients (221 first-timers and 23 recurrent) were included in this study. Results: The stroke recurrence rate in 5 years was 9.4%, the readmission rate was 39.3%, and the mortality rate was 2.0%. The number of patients hospitalized for stroke was greater among men than among women. Of the patients, 60.7% had an underlying disease. With regard to daily life abilities, over 70% of participants needed more than moderate dependence and about 40% of participants had more than mild cognitive impairment. More than 50% were moved to wheelchairs or stretcher cars. The difference in the stroke readmission rate between recurrent and non-recurrent patients was statistically significant. Conclusions: Based on our findings, a program to prevent recurrence of stroke should be developed to considering age, ability of daily living, place of discharge, gait ability at discharge, and place of discharge.

The purpose of this study was to investigate the effect of strength exercise program(60 minutes/day, 3 times/week) on health-related fitness and the factor of metabolic syndrome in the older at senior care facilities during 12 weeks. Twenty-seven volunteers were recruited for the study and divided into two groups: 15 persons(82.6yrs) undertook a continuous 12 weeks strength exercise program(EG), and 12 persons(78.9yrs) served as a control group(CG). The data process of this study calculated as mean(M) and standard Deviation(SD) of all measured value, used repeated measure ANOVA, and paired t-test. The significant level of hypothesis verification is set-up as α=.05. After 12 weeks in EG, health-related fitness increased by an average of 15.2% for right grip strength(p<.05), 26.9% for left grip strength(p<.05), 32.7% for chair stand(p<.05), 92.5% for one leg stand(p<.05), 29.6% for sit and reach(p<.05), and 34.5% for TUG(p<.05); CG showed no difference between pre and post. In the factor of metabolic syndrome, Systolic BP(3.1mmHg) and fasting blood glucose(7.4mg/dl) decreased in the EG group(p<.05). In summary, the strength exercise program leads to a genuine increase in health-related fitness and decrease in the factor of metabolic syndrome in the older adults. The well planned strength exercise seems to be an important intervention to improve function fitness in this population.
