노인인구의 급증에 따라 노인 건강에 대한 관심이 증가하였고 노인 낙상을 발견하는 방법에 대한 관심도 함께 대두되기 시작하였다. 낙상 사고의 경우 낙상을 일으킨 원인보다 낙상이 제때 감지되지 않아 발생하는 이후의 상황이 더욱 심각한 결과를 초래한다. 따라서 낙상이 발생했을 때, 바로 낙상을 감지할 수 있는 시스템 구축이 필요하다. 다양한 낙상 검출을 위한 방법이 존재하지만 그 중 착용이 쉽고 원격지에서 관찰 및 관리가 가능한 웨어러블(Wearable) 기기의 센서 데이터를 사용한 낙상 검출을 진행하였다. 본 논문에서는 머신 러닝 모델들을 사용해서 낙상 검출 성능 비교 및 적절한 모델을 제안한다. 기계 학습 기반의 모델인 결정 트리(Decision Tree), 랜덤 포래스트(Random Forest), SVM(Support Vector Machine)을 사용하여 실제 측정된 데이터에 낙상 검출 학습 능력을 정량화하였다. 또한, 모델의 입력 값에 적용한 데이터 분할, 전처리 및 특징 추출 방법을 통해서 효율적인 낙상 검출을 위한 기계학습 관점에서의 타당성을 판단하고자 한다.

본 논문에서는 낙상과 비낙상 구별을 위한 분류 모델을 제안한다. 일상생활과 낙상을 구분해 내는 것은 낙상이 발생하기 이전에 감지하고 사고를 예방할 수 있다. 낙상은 일상생활 중 일어나기 쉬우며, 노인들에게는 골절 및 기관 파열 등과 같은 심각한 부상을 초래할 수 있기 때문에 낙상 방지를 위한 낙상과 비낙상 행동의 구분은 중요한 문제이다. 따라서 실시간으로 수집되는 다양한 활동에서의 센서 데이터를 활용하여 낙상과 비낙상의 행동을 구분하였다.

The purpose of the study was to examine the effects of the Fall Prevention Education Program (FPEP) on those providing direct care in elderly care facilities regarding fall-related knowledge, fall-related burden, and caring behaviors for fall prevention. The FPEP developed in the study was implemented for 80 minutes per session and four sessions in total. Participants included a total of 47 subjects, 24 in the experimental group and 23 in the control group. The program was implemented from July 16 through August 31, 2012. Data were analyzed using ${\chi}^2$-tests, Fisher's exact probability tests, independent t-tests, and analyses of covariance using the SPSS/Win 19.0 program. According to the pre-and post-test, the experimental group participated in the program showed an increase in fall -related knowledge (t=6.71, p<.001), a decrease in fall-related burden (t=-2.31, p=.026), and an increase in caring behaviors for fall prevention (F=49.50, p<.001) as compared to the control group. The results of the study demonstrated that the FPEP developed for those providing direct care in elderly care facilities was an effective intervention for decreasing fall-related burden and increasing fall-related knowledge and caring behaviors for fall prevention.

The aim of this study was to investigate the effects of an one-to-one fall prevention education on the falls and fall factors of adults who have had a stroke. 17 adults who have had a stroke were recruited and a total of four sessions of weekly one-to-one fall prevention educational program was developed considering the stroke population's cognitive abilities. Each sessions were composed of different fall-related subjects of introduction of fall, fall prevention exercise, fall prevention assistive device, and fall prevention environment modification. Dependent variables were the number of fall and fall danger in the recent month, balance ability, fear of falls, fall efficacy and depression. After four sessions of one-to-one fall prevention education, participants showed significantly positive changes in all dependent variables except for the balance ability(p<.05). An one-to-one fall prevention education to adults with stroke could decrease the number of fall and fall danger, fear of falls, depressive symptoms and fall efficacy. In order for the stroke adults to remain safely in their community and hospital, an one-to-one fall preventive education considering their cognitive level is needed.

Objectives: This study was to investigate fear of falling and related factors in elderly living alone based on fall experience. Methods: Participants were 404 elderly women(faller=148, non-faller=256) over 65 years who were homebound living alone in Jeollanam-do Province. Face-to-face interviews were conducted using questionnaires from April $23^{th}$ to June $9^{th}$ 2013. The questionnaires consisted of demographic variables, fall experience, Fear of falling questionnaire(FOFQ), Falls Efficacy Scale(FES) and Center for Epidemiologic Studies Depression(CES-D). The collected data were analyzed using the SPSS version 14.0. Results: The fear of falling and the influential factors were different according to fall experience. Regression model for fear of falling in fallers significantly accounted for 46.1%(F=6.71, p<0.001); difficulty of performing activity, depression, fall-efficacy, static balance and assistive devices. Regression model for fear of falling in non-fallers significantly accounted for 55.2%(F=15.16, p<0.001); fall-efficacy, environmental hazards, difficulty of performing activity, risk of nutrition, housing type, dizziness and assistive devices. Conclusion: Results demonstrate that fall is an important health problem for elderly women living alone, and show fall experience for factors influencing fear of falling. These results could be used in the developing fall prevention programs.

This study is to design an effective fall-prevention nursing program. Researchers investigated the current condition and risk factors for falls in the small-medium sized rehabilitation hospital with descriptive research. We conducted integrative literature review to reflect the current approach of fall-prevention nursing program. We found that the risk factors for falls are related to the characteristics of clinical setting of the hospital. We suggested the nursing intervention with applying fall risk assessment scale that is sensitive to the elderly population and the intervention that shows maximum effect. In conclusion, this study proposed the way of selecting an effective fall-prevention nursing program based on a clinical setting and prospective of its application. This will contribute to the improvement in nursing practice with the critical view in hospital fall.

Automatic fall-detection algorithms using video-data are proposed. Six types of fall-feature parameters are defined applying the optical flows extracted from differential images to principal component analysis(PCA). One fall-detection algorithm is the simple threshold method that a fall is detected when a fall-feature parameter is over a threshold, another is to use the HMM, and the other is to combine the simple threshold and HMM. Comparing the performances of three types of fall-detection algorithm, the algorithm combining the simple threshold and HMM requires less computational resources than HMM and exhibits a higher accuracy than the simple threshold method.
