Purpose: The purpose of this study was to determine the incidence and influencing factors of falls in the institutionalized elderly. Method: A descriptive survey design was used with a convenience sampling of 430 institutionalized elderly. Data were collected using a structured questionnaire. Results: The falls rate after admission in institution was 8.4%. Types of injury after falls were mostly contusion and fracture. Interventions for fall prevention were environmental management and regular evaluation of risk factors for falls. Fall experience was significantly different according to admission periods. Type of falls was significantly different according to state of ADL. Predictors for falls were longer admission periods and dependent state in ADL. Conclusion: Falls is important health related problem in the institutionalized elderly, so effective fall prevention program is needed for their health promotion.

Purpose: The purpose of this study was to investigate the experience of falls, the fear of falling and fall efficacy and identify the predictors of falls in the elderly at senior citizens' centers. Method: The subjects of this study were 106 elders who used senior citizens' centers in Chungcheongbuk-do, Korea. Data were collected from May to June, 2006 through a survey using a structured questionnaire. Result: Of the elderly sampled, 35.8% experienced falls during the last 1 year. Of falls experienced by the elderly, 53% occurred indoors, 47% outdoors, 15.8% in the bathroom or toilet. In addition, 57.8% of the elderly had injuries on the hip and waist related with falls. The fear of falling was higher in those with experience in falls than in those without. Factors affecting the elders' falls were age (OR=1.113, 95% CI=1.012-1.224), the number of chronic disease (OR=2.342, 95% CI=1.365-4.019) and the fear of falling (OR=4.279, 95% CI=1.901-9.634). The predictor of the frequency of falls was fall efficacy ($R^2=24.9$). Conclusion: As a result, it is essential to develop fall prevention programs based on the fear of falling, fall efficacy, chronic diseases and medication state. And in senior citizens' centers, fall prevention safety education should be activated as a health promotion program.

While institutional matters such as improvement on Basic Guidelines for Construction Safety are greatly concerned to reduce falling accidents at construction sites, there are short of studies on how to practically predict accident signs at construction sites and to preemptively prevent them. As one of existing accident prevention methods, it was attempted to build the early warning system based on standardized accident scenarios to control the situations. However, the investment cost was too high depending on the site situation, and it did not help construction workers directly since it was developed to mainly provide support operational work support to safety managers. In the long run, it would be possible to develop the augmented reality based accident prevention method from the worker perspective by extracting product information from BIM, visually rendering it along with site installation materials term and comparing it with the site situation. However, to make this method effective, the BIM model should be implemented first and the technology that can promptly process site situations should be introduced. Accordingly, it is necessary to identify risk signs through lightweight image processing to promptly respond only with currently available resources. In this study, it was intended to propose the system concept that identified potential risk factors of falling accidents by histogram equalization, which was known as the fastest image processing method presently, used visual words, which could enhance model classification by wording image records, to determine the risk factors and notified them to the work manager.

Objective: The aim of this study is to investigate the effects of whole body vibratory stimulation on muscle strength, balance, and fall efficacy among super-aged women. Design: Randomized controlled trial. Methods: Twenty-eight super-aged women over 80 years of age were assigned to either the experimental group (n=14) and control group (n=14). The experimental group received an exercise program that used the whole body vibratory stimulation with a frequency of 30 Hz and amplitude of 3 mm, and the control group received an exercise program without vibratory stimulation. Intervention was provided for 4 weeks, 3 sessions per week, and 30 minutes per session. In order to measure lower extremity muscle strength the 30-second chair stand test (CST) was used. The Berg Balance Scale (BBS) was used to measure dynamic balance. Static balance was measured by tracking the path length, velocity, and area of the center of pressure (CoP). The Falls Efficacy Scale (FES) was used to measure the subjects' fear of falling. Results: Both the experimental and control group demonstrated statistically significant increase in muscle strength, dynamic balance, and fall efficacy (p<0.05). Only the experimental group showed significant improvements in static balance before and after the intervention (p<0.05). The experimental group showed significantly greater improvements in CST, BBS, and CoP (path length, velocity) than control group (p<0.05). Conclusions: Whole body vibratory stimulation exercise is shown to be a safe and appropriate physical therapy intervention method to enhance muscle strength, balance, and fall efficacy of super-aged women.

Objectives: People who have chronic diseases, as well as gait imbalance or psychiatric drug use, may be susceptible to injuries from falls and slips. The purpose of this study was to evaluate the effect of musculoskeletal diseases on incidental fall-related injuries among adults in Korea. Methods: We analyzed data from the 4th Korea National Health and Nutrition Examination Survey (2007-2009), which are national data obtained by a rolling survey sampling method. The 1-year incidence of fall-related injuries was defined by health service utilization within the last year due to injury occurring after a slip and fall, and musculoskeletal diseases included osteoarthritis, rheumatoid arthritis, osteoporosis, and back pain. To evaluate the effects of preexisting musculoskeletal diseases, adults diagnosed before the last year were considered the exposed group, and adults who had never been diagnosed were the unexposed group. Results: The weighted lifetime prevalence of musculoskeletal disease was 32 540 per 100 000 persons. Musculoskeletal diseases were associated with a higher risk of fall-related injury after adjustment for sex, age, residence, household income, education, occupation, visual disturbance, paralysis due to stroke, and medication for depression (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.03 to 1.93). As the number of comorbid musculoskeletal diseases increased, the risk of fall-induced injuries increased (p-value for trend <0.001). In particular, patients who had any musculoskeletal condition were at much higher risk of recurrent fall-related injuries (OR, 6.20; 95% CI, 1.06 to 36.08). Conclusions: One must take into account the risk of fall-related injuries and provide prevention strategies among adults who have musculoskeletal diseases.

Due to the rapidly aging population, the death rate of elderly people by safety accidents has been increasing. In particular, precautions are needed for falls prevention because they either directly or indirectly cause death. In the case of elderly people, most of the fall accidents occur in dense residential areas, and particularly, the staircase poses a risk of falling. Therefore, a safety assessment should be performed from the design phase. However, in general, staircases are designed using existing stair data or only aims to satisfy the installation criteria. Laws and regulations only define minimum requirements for safety, so it is not possible to prevent fall accidents even if they satisfy the requirements. Therefore, this study proposes a simulation-based method for evaluating the safety of staircases. The behavioral characteristics of the elderly are implemented to an virtual user in a virtual space including staircases, and fall accidents are evaluated by the evaluation logic related to the behavioral characteristics. The result shows that the safety of staircases can be preevaluated and reflected on the design to reduce the possibility of fall accidents of the elderly.

본 연구는 기존 낙석방지울타리의 시험 방법 중 수직 낙하시험을 중심으로 낙석방지울타리의 성능평가에 대한 시험방법을 제시하기 위해 현장시험을 실시하였다. 국내의 낙석방지울타리 지지 능력을 알아보는 시험은 보통 철망, 지주, 와이어로프를 합친 것으로 시험을 실시하며, 낙석의 충돌위치를 철망의 중앙을 중심으로 실시해 왔다. 하지만 실제 현장에서 낙석이 철망이 아닌 지주에 직접 타격했을 경우, 즉 지주에 직접 타격에 관한 국내 시험적 논문 및 데이터가 전무한 것으로 파악되었다. 따라서 낙석방지울타리(고속도로 형식 2호)를 중심으로 100kJ급의 낙석에너지에 대한 충격을 지주에 타격 했을 시 변위량을 분석하고 기존의 낙석방지울타리 시험과 비교·분석하였다.

AHP를 사용하 교통망 사고 예방 처리 기법은 아직 우리나라에서는 처음 시도되어지는 예방법이라 할수 있다. 인공지능을 사용하여 사고처리하는 방법을 시도를 하였보았으나 그 외의 방법은 문외한이라 할수 있을 정도로 우리나라에서는 보기드문 현상이라 할수 있다. 따라서 계층분석기법을 사용하여 요소분석보다 훨씬 나은 처리방법이므로 좀더 나은 기법이 될 것 같고 다음으로 처리되는 방법의 기본 모티브가 될 영향이 크다라고 한다.

Objective: This study aims to draw the characteristics of occupational accidents occurred in cabling work, and assess accident severity based on occupational injury data. Background: Accident factors and accident risk are different by the place of work in cabling work. Field managers require information on accident prevention that can be easily understood by workers. However, there has been a lack of studies that focus on cabling work in Korea. Method: This study classifies 450 injured persons caused in cabling work by process, and analyzes the characteristics of occupational injuries from the aspects of age, work experience and accident type. This study also analyzes accident frequency and severity of injury. Results: Results show that preparing/finishing (33.3%) was the most common type of cabling process in injuries, followed by maintenance (28.4%), routing/income (23.1%) and wiring/installation (15.1%) process. The critical incidents in the level of risk management were falls from height in the routing/incoming process, and falls from height in the maintenance process. And, incidents ranked as 'High' level of risk management were slips and trips, fall from height and vehicle incident in the preparing/finishing process, and fall from height in the wiring/installation process. Conclusion and Application: The relative frequency of accident and its severity by working process serve as important information for accident prevention, and are critical for determining priorities in preventive measures.

Purpose: This study was conducted to construct evidence based clinical guidelines and to develop nursing process based performance measures for prevention and management of pressure ulcers, falls and pain. Method: Clinical guidelines were drafted through a comprehensive review of relevant literature, national guidelines and hospital protocols. The proposed guidelines were reviewed by a panel of experts and 90 hospital nurses, and refined on the basis of their suggestions. Nursing process based performance measures were developed based on the clinical guidelines and content validity was examined by surveys from 90 hospital nurses. Results: All items, except timetable for position change and pressure ulcer nursing record, in the guidelines for prevention and management of pressure ulcer were appropriate. Most items, except fall risk assessment tools, were appropriate for the guidelines of fall prevention. All other items, except the purpose of pain management, were appropriate for the guidelines of pain management. Performance measures developed in this study were acceptable as a tool to evaluate quality of nursing care. Conclusion: Nursing process based performance measures provide important indicators to monitor whether necessary nursing care is implemented and can be used as the primary resources to improve quality of nursing services.
