Currently, safety accidents in construction area are managed regardless of the size. Therefore, the objective of this study is to conduct for developing the quantitative risk assessment according to large and small and medium-sized construction sites. The scope of this study is limited to the fall accidents which is the biggest accidents in the construction sites. the regression analysis was conducted based on the collected data. As a result, it was confirmed that there was a statistically significant difference between larce and small and medium-sized construction sites. This study is expected to be used as basic data for research on the development of a risk quantitative model for small and medium-sized construction sites in the future.

Purpose: The study investigated pain and falls as psychological factors in Total Knee Replacement patients and examined the relationship between these factors. Methods: Ninety-six total knee replacement patients aged 69.31±7.01 (male: 21, female: 75) participated in the study. Post-surgery pain was assessed on a visual analog scale, and fall risk scores were evaluated on fall fear and fall efficacy scales. Other psychological factors assessed included national anxiety and trail anxiety, fear prevention, Beck depression score, and psychological health measures. The data were analyzed using SPSS version 22.0. Results: A statistically significant correlation was found between pain before surgery and FES fall fear score before surgery (p < 0.05). A statistically significant correlation was found between pain after surgery and PWBS fall fear score after surgery (p < 0.05). A statistically significant correlation was found between state anxiety and PWBS, Trail anxiety (p < 0.05). A statistically significant correlation was also found between trail anxiety and BDI, PWBS (p < 0.05). State anxiety and fear avoidance before surgery were found to affect trail anxiety, and pain before surgery and fall fear score before surgery were found to affect FES. In addition, PWBS was found to affect BDI. Conclusion: The study confirms that increased pain in Total Knee Replacement patients can be a risk factor for falls. In addition, fall fears increase fear avoidance and cause psychological deterioration. This suggests that efforts should be made to reduce pain and to manage psychological factors.

Purpose: We analyzed the incidence of falls and the related factors, circumstances, and consequences associated with falls in stroke patients. Methods: We recruited 127 stroke patients and used a self-reported questionnaire to measure fall prevalence rates and the related factors, circumstances, and consequences of falls. The chi-square test was used to establish associations between related factors. Results: The prevalence of falls in stroke patients was 69.3%, and was associated with gender and time since the stroke. Falls occurred 2-5 times (55.4%) poststroke and most subjects first fall in the 2$\sim$6 month (46.5%) after the stroke. Most (55%) falls occurred at the hospital. Walking was the most frequent circumstance for falls (38.5%). Most (54.4%) falls led to consequences such as fractures, ligament strains, bruises, or abrasions. Conclusion: Fall-prevention strategies decrease the number of falls and the severity of fall-related injuries. These data support the concept of preventive strategies for falls in stroke patients who are at risk.

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.

This research aims to identify risk factors for fall accidents at small and medium-sized construction sites through a comprehensive regression analysis. Initially, the study involved collecting a decade's worth of fall accident data from these sites. A t-test confirmed a significant variation in the treatment duration following fall accidents between two distinct groups: small and medium-sized versus large construction sites. Subsequently, a regression analysis was conducted to establish a model highlighting the risk factors associated with safety accidents. The factors influencing fall accidents were determined to be, in descending order of impact, the time of the accident, the day of the accident, and the occupational classification. The findings from this study are expected to serve as foundational data for enhancing policies and conducting statistical analyses tailored to construction site sizes. They also provide crucial information for future research on risk quantification at small and medium-sized construction sites.

Background: The Berg Balance Scale (BBS) and the Fullerton Advanced Balance (FAB) scale have been used to assess balance function in patients with chronic stroke. These clinical balance scales provide information about potential risk factors for falls. Objects: The purpose of this study was to investigate the incidence of and risk factors of falls and compare the predictive values of the BBS and FAB scale relative to fall risk in patients with stroke through receiver operating characteristic analysis. Methods: Sixty-three patients with stroke (faller=34, non-faller=29) who could walk independently for 10 meters participated in this study. The BBS and FAB scale were administered. Then, we verified the cut-off score, sensitivity, specificity, and the area of under the curve. Results: In this study, the BBS and FAB scale did not predict fall risk in patients with stroke in the receiver operator characteristic curve analysis. A cut-off score of 37.5 points provided sensitivity of .47 and specificity of .35 on the BBS, and a cut-off score of 20.5 points provided sensitivity of .44 and specificity of .45 on the FAB scale. Conclusion: The BBS and FAB scale were not useful screening tools for predicting fall risk in patients with stroke in this study, but those who scored 37.5 or lower on the BBS and 20.5 or lower on the FAB scale had a high risk for falls.

Purpose: The purpose of this study was to validate the Edmonson psychiatric fall risk assessment tool (EPFRAT) for psychiatric inpatients. Methods: Data from retrospective study were collected from 670 adult inpatients in two departments of mental health medicine of a tertiary general hospital by reviewing their electronic medical records. There were 41 patients who experienced falls and 629 patients who did not experience falls during the period from January to December 2019. Data were analyzed by sensitivity, specificity, positive predictive value, negative predictive value, and a receiver-operating characteristic curve (ROC) for validity assessment using the IBM SPSS/WIN 26.0 program. Results: Factors affecting falls were the participant's age, guardian's residence, high-risk determination at the time of admission, and comorbidity. At the 85 points where the point of sum of the sensitivity and specificity was largest, the sensitivity, specificity, positive predictive value, and negative predictive value of EPFRAT were 92.7%, 79.7%, 22.9%, and 99.4%, respectively. The area under the ROC to assess the overall validity of the tool was .92 (95% CI 0.89~0.94). Conclusion: The EPFRAT was proved to be valid and reasonable for predicting falls in psychiatric inpatients. Based on the results of this study, it could be used for the assessment of high-risk patients for falls in psychiatric units.

PURPOSE: The purpose of this study was to investigate the quality of life related to fall experiences in chronic stroke patients. METHODS: This cross-sectional study included 117 patients with stroke from 3 hospitals in D metropolitan city. General characteristics, including fall experiences and quality of life, were assessed through a face-to-face interviews conducted in a quiet place using a questionnaire. Measurement of quality of life in stroke patients was conducted using the Korean Stroke Specific Quality of Life Scale (SS-QOL). To identify the SS-QOL items related to fall experiences, the items of the SS-QOL were considered as independent variables, and the variables that were significantly different according to fall experiences were identified using a univariate analysis. A binary logistic regression was then performed using fall experiences as the independent variable. RESULTS: According to the univariate analysis, self help activities, social role, and upper extremity function were significantly lower in the fall group than that in the non-fall group (p<.05). The findings of the binary logistic regression confirmed that social roles and upper extremity function were the SS-QOL items that were related to fall experience in chronic stroke patients. CONCLUSION: These findings suggest that social roles and upper extremity function may be risk factors for fall experience in patients with chronic stroke.

Purpose: The purposes of this study were to examine 1) functional status at 2 months after hip fracture surgery 2) health care utilization after a fall episode and 3) fear of falling experienced during first 2 months after a fall episode. Method: With a convenient sample of 99 elderly from six university or general hospitals with hip fracture from a fall, data were collected at 2-3 days before discharge and at 2 months after hip fracture surgery. Result: 1) At 2 months after hip fracture from a fall, significant proportion (25.3%) of elderly was not able to walk indoors. 2) Average length of hospital stay was 27.6 days with a range of 8 to 86 days. About 51% subjects received physical therapy during hospital stay, and only 6.1% subjects received physical therapy following discharge from the hospital. 3) Significant proportion (72.7%) had fear of falling after the fall episode. About 51% reported that they restricted their activities because they had fear of falling. Conclusion: Fall is a dreaded event which result in loss of independence and restriction of activity. Development and application of fall prevention program is critical especially for those with risk factors of fall.

Community-based centres were surveyed to determine the frequency of and risk factors for falls among elderly Koreans. We examined fall-related risk factors, including physiological and physical health, psychosocial functions, self-reported physical capacity and activity, vision, and the use of medication, among 351 elderly people aged 65 years or older, with ambulatory. Forty-two per cent of elderly Korean subjects reported at least one episode of falling in the previous 12 months, $38\%$ of whom had consequences that required either the attention of a physician or hospitalization. Factors significantly associated with an increased risk of falling were a restricted activity during the previous five years (adjusted OR 1.3), use of alternative therapy (adjusted OR 2.7), low knee flexor and extensor-muscle strength (adjusted OR 1.21 and 1.20), and poor balance with closed eyes (adjusted OR 8.32). We conclude that falls among older persons living in the community are common in Korea and that indicator of bad health and frailty or variables directly related to neuromuscular impairment are significant predictors of the risk of falling.
