Recently, social technologies have been created to solve problems from businesses for the establishment of generational solidarity ecosystem in terms of employment, residential space, network and social capital, age, cognitive and environmental aspects. This is senior-friendly healthcare business system aimed at meeting the senior needs for health life to enjoy active consumption culture life even after retirement, becoming a catalyst for minimizing generational conflicts, preventing the cognitive and physical deterioration of seniority in the areas of life healthcare, fitness and well-aging, and expanding into systems necessary for seniority self-reliance. We would like to draw up the development and requirements of the concept of the service platform for the study of collective characteristics for generation solidarity with senior class and the establishment of a customized senior health life system for generation solidarity. This system is characterized by a platform that can prevent the decline of seniors' cognitive and physical functions and enhance emotional stability. It is significant in providing feedback on the risk perception index, fall index, and prevention training index information to the child through the analysis and extraction of the senior health index for risk perception, fall probability, and fall prevention.

Tunnel portals are often located in areas where the risk of rock fall and/or detachement of rock fragments from rocky slopes is high. In this case it is necessary to design the portals so as to protect the road (i.e. using an artificial tunnel) or to instal structures that are able to intercept falling blocks on the slope. This paper deals with the design problems of these structures and includes a special analysis of net fences which have undergone a remarkable technological improvement over recent years.

Balance function is one of the joint factors to determine fall in risk theory. It helps to moderate the progression and riskiness of falls for detecting balance and fall risk factors. Nevertheless, the objective measures for balance function require expensive equipment with the assessment of any expertise. We establish the existence and uniqueness of a multi-order fractional differential equations based on ${\psi}$-Hilfer operator on time scales with balance function. This class describes the dynamic of time scales derivative. Our tool is based on the Schauder fixed point theorem. Here, sufficient conditions for Ulam-stability are given.

Objective: This study aimed to assess the effectiveness of a balance training program in improving balance and functional independence to reduce fall risks among community-dwelling elders. Design: A multi-center randomized controlled trial Methods: A total of 66participants were randomly assigned to a balance training group or a control group. The balance training program, conducted three times a week for 32 weeks, included warm-up exercises, main balance training exercises, and cooldown stretch exercises. Outcome measures included the Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), and Modified Barthel Index (MBI). Results: The balance training group demonstrated significant improvements in all outcome measures, indicating enhanced balance, improved functional mobility, and increased independence in activities of daily living. In contrast, the control group showed only slight improvements in BBS, TUGT and MBI scores. Conclusions: These findings provide evidence supporting the effectiveness of balance training programs in reducing fall risk and promoting health and wellbeing among community-dwelling elders. Future research should aim to refine the design of these programs and assess the sustainability of the observed improvements.

Purpose: This study was done to identify factors influencing falls in inpatients. A comprehensive analysis of individual, disease, and environment related factors and an assessment of being in a risk factor group were included in the data. Method: The medical records of 325 inpatients were reviewed. Data were collected from January to July 2003. Frequencies, 1-test and $X^2-test$ were used to analyze the data and the SPSS program was used. Results: Individual-related factors for inpatients falls were age, drinking and weakness. Disease-related factors for inpatients falls were diagnostic department, admission from ER or OPD, admission by wheelchair or orther method and activity status. Environment-related factors for inpatient falls were re-education and side-rails. Assessment of the risk factor group related factors were age, history of falls, body balance, depression, communication, medication, chronic disease, urinary condition and total score for risk factors. Conclusion: Experienceing a fall among Korean inpatients was associated not only with individual factors, but also with disease and environmental factors. The findings of this study suggest that broad intervention programs should be provided to prevent inpatient falls.

Falls are common after stroke and most frequently related to loss of balance while walking. Consequently, preventing falls is one of the goals of acute, rehabilitative, and chronic stroke care. The purpose of this study was to investigate the incidence and risk factors of falls and to determine how well the Falls Efficacy Scale (FES), Timed Up and Go test (TUG), and Berg Balance Scale (BBS) could distinguish between fallers and non-fallers among stroke patients during inpatient rehabilitation. One hundred and fifteen participants with at least 3 months post-stroke and able to walk at least 3 m with or without a mono cane participated in this study. Fifty-four (47%) participants reported falling, and 15 (27.8%) had a recurrent fall. Logistic regression analysis for predicting falls showed that left hemiplegia [odds ratio (OR)=4.68] and fear of falling (OR=5.99) were strong risk factors for falls. Fallers performed worse than non-fallers on the FES, TUG, and BBS (p<.05, p<.01, respectively). In the receiver operator characteristic curve analysis, the TUG demonstrated the best discriminating ability among the three assessment tools. The cut-off score was 22 seconds on the TUG for discriminating fallers from non-fallers (sensitivity=88.9%, specificity=45.9%) and 27 seconds for discriminating recurrent fallers from single fallers and non-fallers (sensitivity=71.4%, specificity=40.2%). Results suggest that there is a need for providing fall prevention and injury minimization programs for stroke patients who record over 22 seconds on the TUG.

Purpose: We studied the correlation between BBS (Berg Balance Scale), Functional Reach Test (FRT), Timed-Up & Go test (TUG), Stability Index (STI), MBI (Modified Barthel Index), and Fall History. Methods: We recruited 20 stroke patients from the Gang Dong Gu Health Care Center in Seoul, Korea. All subjects could walk with or without an assisting device. Subjects first completed a questionnaire pertaining to their fall history and Activity of Daily Living (MBI), and then were evaluated with BBS, TUG, FRT, and STI. We used the Tetrax posturography system that calculates a STI based on fluctuations in vertical ground reaction forces. The data were analyzed using a Pearson Correlation Coefficient. Results: The BBS and FRT (p<0.05) and MBI (p<0.01) showed a significant positive correlation. BBS negatively correlated with STI and TUG (p<0.01). Fall history and BBS, TUG, MBI, FR, STI did not correlate. Conclusion: The BBS helps predict weight shifting, walking, and ADL, but is not good for predicting fall risk. So, we need to study about factors that affect falling.

In 2015, the number of senior citizens aged 65 and over in Korea was 6,662,400, accounting for 13.1% of the total population. Along with these social phenomena, risk information related to the elderly is increasing every year. In particular, a fall accident caused by a fall can cause serious injury to an elderly person, so special attention is required. Therefore, in this paper, we implemented a system that monitors fall accidents and informs them in real time to minimize damage caused by falls. To this end, beacon-based indoor location positioning was performed and biometric information based on an integrated module was collected using various sensors. In other words, a multi-functional sensor integration module was designed based on Arduino to collect and monitor user's temperature, heart rate, and motion data in real time. Finally, through the analysis and prediction of measurement signals from the integrated module, damage from fall accidents can be reduced and rapid emergency treatment is possible. Through this, it is possible to reduce the damage caused by a fall accident, and rapid emergency treatment will be possible. In addition, it is expected to lead a new paradigm of safety systems through expansion and application to socially vulnerable groups.

본 연구는 전국단위의 패널데이터를 사용하여 한국노인의 인구사회학적요인, 보조기구사용, 신체건강상태, 정신건강상태, 건강행태 중 낙상에 영향을 미치는 요인을 도출하는 것을 목적으로 한다. 이러한 연구목적을 달성하기 위하여 고령화연구패널조사(KLoSA)의 제 1차와 제 2차 조사 자료를 분석에 활용하였다. 연구대상자는 2006년 제 1차 조사시점에서 만 65세 이상의 참여자를 기준으로 제 1차 조사와 제 2차 조사에 모두 참여한 응답자만(N=3,311)을 선택했으며 2008년 제 2차 조사 자료에서 낙상경험을 종속변수로 추출했다. 인구사회학적 요인들, 신체기능 및 질병유무, 건강행태 등에 대한 변수들은 시간의 선행 조건이 충족되어야 하므로 1차 조사로 부터 변수들을 추출했다. 분석방법으로는 변수에 따른 낙상경험 차이가 존재하는지 밝혀내기 위해 x² 혹은 t-test를 실시하였으며 독립변수들이 낙상경험에 유의미한 영향을 미치는지 고찰하기 위하여 로지스틱 회귀분석을 실시하였다. 분석결과로 성, 동거인여부, 거주지역, 보조기구사용, 질병의 수, 우울, 운동 및 흡연 여부에 따라 낙상경험에 통계적으로 유의미한 차이를 보였다. 또한 로지스틱 회귀분석에서 모든 변수를 통제하였을 때 여성, 청각보조기구사용자, 질병수가 2가지, 3가지 이상일 때, 우울이 있는 사람과 운동을 주 5회 이상 하는 응답자의 낙상경험 오즈가 그렇지 않은 사람에 비해 더 증가하였다. 반면 비만, 치매의심, 현재흡연자의 낙상경험 오즈는 준거카테고리에 비해 더 낮아졌다. 결론적으로 질병수 3가지 이상과 우울이 있는 사람의 낙상경험 오즈는 그렇지 않은 사람에 비해 2배 이상 높았기 때문에 낙상예방에 더욱 주의가 요구된다고 할 수 있다. 신체건강상태와 정신건강상태 모두 낙상과 관련이 있으므로 재가노인들의 낙상을 방지하기 위해서는 이러한 요인들을 갖고 있는 노인들을 위한 체계적인 지원이 이루어져야 하겠다.
