In recent years,under the influence of multiple factors such as traditional ideas and living economic conditions,the aging population in China continues to increase.Most of the elderly are more inclined to aged at home,and the first places for elderly activities are communities and the surrounding environment,which greatly affects the convenience of life and happiness of the elderly.In this paper,Changxindian area in Fengtai District of Beijing was as the research object,and detailed calculation and analysis were carried out by using POI data and arcGIS software.The relative location of residential areas and surrounding public toilets was explored,and the best location of public toilets in the daily walking area under the model of community home-based care for the elderly was further studied.

Home-based nursing for improvement of quality of life and depression in patients with postpartum depression

BACKGROUND Postpartum depression is a common mental illness in puerpera,with an incidence of approximately 3.5%-33.0%abroad,and the incidence of postpartum depression in China is higher than the international level,reaching 10.0%-38.0%.Providing effective nursing care in clinical nursing activities is one of the key points of obstetrical care.However,little research has been designed to investigate the positive role of home-based nursing in the prevention of postpartum depression.AIM To study the effect of home-based nursing for postpartum depression patients on their quality of life and depression.METHODS The clinical data of 92 patients with postpartum depression treated at our hospital were retrospectively analyzed.The patients were grouped according to the nursing methods used;40 patients receiving basic nursing were included in a basic nursing group,and 52 receiving home-based nursing were included in a home-based nursing group.Depression and anxiety were evaluated and compared between the two groups.The estradiol(E2),serotonin(5-hydroxytryptamine,5-HT),and progesterone(PRGE)levels were measured.RESULTS The SAS and SDS scores of the home-based nursing group were significantly lower than those of the basic nursing group(P<0.05).The E2 and 5-HT levels of the home-based nursing group were significantly higher than those of the basic nursing group,but the PRGE level was significantly lower than that of the basic nursing group.The GQOLI-74 scores(material,social,somatic,and psychological)and nursing satisfaction were significantly higher in the home-based nursing group(P<0.05).CONCLUSION Postpartum depression through home-based nursing can effectively alleviate depression and improve the quality of life of patients,help modulate their serum E2,5-HT,and PRGE levels,and improve their satisfaction with nursing care.

Evaluation of the intervention of home-based pulmonary rehabilitation in patients with chronic obstructive pulmonary disease

Objective:Chronic obstructive pulmonary disease(COPD)can be prevented and treated,although presenting with persistent airflow restriction;the airflow restriction caused by COPD is mostly progressive.In recent years,more attention has been paid to the home-based pulmonary rehabilitation(PR)and its influence on COPD.Exercise training is the basic constituent of PR.However,it is not clear which exercise trainings are the ideal ways to deliver home-based PR.Methods:In this review,we focus on the effect of home-based exercise training on patients with COPD.We searched literature,which was necessarily required to be randomized controlled trails(RCTs)from the establishment of the four respective databases(Medline,PubMed,Web of Science,and China National Knowledge Infrastructure)from January 2008 to January 2018.We used the Cochrane collaborative“risk of bias”tool to assess the quality of evidence.A total of 21 trials(1694 participants)were included.Through the analysis of the literature,we find that a simple,low-cost,and low-intensity family-based lung-rehabilitation plan to adapt to the real life may lead to the improvement of the ability to exercise,the reduction of the difficulty in breathing,and the improvement of carrying out daily activities.Results:In the exercise training of home-based PR,lower limb exercise(LLE)training demonstrated a more perceptible effect in improving the quality of life of patients with COPD.At the same time,the combination of LLE training,breathing training,and upper limb exercise training is more obvious than the simple LLE training.In addition,home-based low-intensity aerobic training may sometimes be no less than the outpatient or center intervention to improve dyspnea,health status,and exercise tolerance.In conclusion,the simple and easy home-based PR exercise program is useful.Long-term home-based PR may require an enhanced need for maintenance.Conclusions:A simple,low-cost,and low-intensity high blood pressure response(HBPR)plan to adapt to the real life may lead to an augmentation in the ability to exercise,a reduction of the difficulty in breathing,and an improvement in carrying out day-to-day activities.HBPR strategies can benefit patients(elderly patients with COPD at home)in the long term.

A Review of Device-Free Indoor Positioning for Home-Based Care of the Aged:Techniques and Technologies

With the development of urbanization,the problem of neurological diseases brought about by population aging has gradually become a social problem of worldwide concern.Aging leads to gradual degeneration of the central nervous system,shrinkage of brain tissue,and decline in physical function in many elderlies,making them susceptible to neurological diseases such as Alzheimer’s disease(AD),stroke,Parkinson’s and major depressive disorder(MDD).Due to the influence of these neurological diseases,the elderly have troubles such as memory loss,inability to move,falling,and getting lost,which seriously affect their quality of life.Tracking and positioning of elderly with neurological diseases and keeping track of their location in real-time are necessary and crucial in order to detect and treat dangerous and unexpected situations in time.Considering that the elderly with neurological diseases forget to wear a positioning device or have mobility problems due to carrying a positioning device,device-free positioning as a passive positioning technology that detects device-free individuals is more suitable than traditional active positioning for the home-based care of the elderly with neurological diseases.This paper provides an extensive and in-depth survey of device-free indoor positioning technology for home-based care and an in-depth analysis of the main features of current positioning systems,as well as the techniques,technologies andmethods they employ,fromthe perspective of the needs of the elderly with neurological conditions.Moreover,evaluation criteria and possible solutions of positioning techniques for the home-based care of the elderly with neurological conditions are proposed.Finally,the opportunities and challenges for the development of indoor positioning technology in 6G mobile networks for home-based care of the elderly with neurological diseases are discussed.This review has provided comprehensive and effective tracking and positioning techniques,technologies and methods for the elderly,by which we can obtain the location information of the elderly in real-time and make home-based care more comfortable and safer for the elderly with neurological diseases.

Feasibility and acceptability of wrist actigraph in assessing sleep quality and sleep quantity: A home-based pilot study in healthy volunteers

Purpose: This study aimed to determine the feasibility and acceptability of actigraphy to monitor sleep quality and quantity in healthy self-rated good sleeper adults at home-based settings. Method: Sixteen healthy volunteers (age > 18) were invited to participate. Each participant was provided with a wrist actigraph device to be worn for 24-hour/day for seven consecutive days to monitor their sleep-wake patterns. Actigraphy data were downloaded using-proprietary software to generate an individual-sleep report. Participants also completed a set of self-reported Health Related Quality of Life (HRQOL) using WHO (five) Well Being Index (WBI) questionnaires. Results: Actigraphy was well accepted by all participants. Only 43.8% of the participants achieved normal total sleep time (TST) and 62.5% had a mean sleep efficiency value below the normal range. Despite a reduced quality of sleep among the participants, the self-reported HRQOL scores produced by the WHO-5 WBI showed a “fair” to “good” among the participants. Conclusions: To maintain healthy well-being, it is vital to have efficient and quality sleep. Insufficient and poor sleep may contribute to various health problems and hazardous outcomes. People often believe they have normal and efficient sleep, not realising they may be developing poor sleep habits. This study found that actigraphy can be easily utilized to monitor sleep-wake patterns at home-based settings. We proposed that actigraphy could be adapted for use in the primary care settings (e.g. community pharmacy) to improve the sleep health management in the community.

Self-management A concept analysis of self-management for cancer patients’ home-based rehabilitation

Objective： To explore and clarify the concept of self-management in the context of cancer patients’ home-basedrehabilitation. This concept analysis will provide a theoretical lens for nurses to help cancer patients to developself-management strategies and enables them to improve their ability in symptom self-management of home-basedrehabilitation. Method： Walker and Avant’s framework （2011） was used to analyse the concept of self-management.Results： Self-management is defined as a dynamic process that involves perception of one’s needs, resource utilisation,problem solving and active participation. Antecedents of self-management include self-efficacy, disease knowledge andsocial support. Improving cancer patients’ ability in symptom self-management can improve their health outcomes andquality of life and reduce healthcare expenditures. Although Strategy and Effectiveness of Symptom Self-Managementscale is perceived as an ideal instrument to measure self-management and thus it is used worldwide, whether thisinstrument fits to measure this concept for cancer patients in Chinese context has still not yet been verified and thusfurther research is needed. Conclusion： According to the concept analysis, nurses should encourage cancer patients toinvolve actively in making a home-based rehabilitation plan and promote their ability in symptom self-management ofhome-based rehabilitation so as to improve their health outcomes and reduce healthcare expenditures.

Functional outcomes after home-based rehabilitation for heroin-induced spongiform leukoencephalopathy

A 22-year-old man with a 2-year history of heroin vapor inhalation developed spongiform leukoencephalopathy and underwent clinical and home-based rehabilitative treatments. Activities of daily living were measured using the Functional Independence Measure at discharge and at 6, 12, and 24 months after discharge. His neurological symptoms gradually disappeared with rehabilitative treatment, and the functional scale scores increased from 55 on admission to 105 at 24 months after discharge. These results suggest that home-based rehabilitation was effective in ameliorating the pathology and improving activities of daily living in this patient with heroin-induced spongiform leukoencephalopathy.

Physiotherapist-led home-based physical activity program versus community group exercise for middle-aged adults: Quasi-experimental comparison

Objectives: Program method, program deliverer and participant preference may be important factors in increasing physical activity adherence and program effectiveness. To investigate this, we compared two physical activity interventions in middle-aged adults. Methods: Using a pragmatic quasi-experimental design, sedentary community dwelling 50 - 65 year olds (n = 2105) were recruited to a non-randomized 6-month community group exercise program (n = 93) or a physiotherapist-led home-based physical activity program (n = 65). The primary outcome was physical activity adherence derived from exercise diaries. Secondary outcomes included the Active Australia Survey, aerobic capacity (step- test), quality of life (SF-12v2), blood pressure, waist circumference, waist-to-hip ratio (WHR) and body mass index. Results: Home-based participants were more likely to be younger, working full-time and not in a relationship (p Thirty-three percent of the group participants attended ≥ 70% of group exercise sessions. Ninety percent of home-based participants received ≥ 4 of the planned 6 telephone support calls. Intention-to-treat analysis found adherence to the physical activity sessions prescribed was the same for both interventions (26% ± 28% vs. 28% ± 35%). Both interventions significantly increased the number of participants achieving self-reported “sufficient” physical activity (p ≤ 0.001) and significantly decreased waist circumference (p < 0.001) and WHR (p 0.05). Conclusion: The physiotherapist- led home-based physical activity program, requiring few resources, appears to have increased the adoption of physical activity and adherence to physical activity program requirements for sedentary middle-aged adults. The home-based program, providing equivalent health benefits to the group exercise program, may be particularly suitable for those not interested in or unable to attend a group exercise program.

Reported National Level Stock-Outs of Home-Based Records—A Quiet Problem for Immunization Programmes That Needs Attention

Home-based records (HBRs) are an important tool for recording and communicating within primary healthcare service delivery. Unfortunately, HBRs are currently unable to fulfil their intended purpose in many communities either because the HBR is not functionally well-designed to serve its objectives, not made available, not fully adopted and/or not appropriately utilized by caregivers and/or health workers. This brief report describes the occurrence of nationally reported HBR stock-outs and HBR financing patterns during 2014 and 2015 across 195 countries reporting immunization system performance data to the World Health Organization and United Nations Children’s Fund. National level HBR stock-outs were reported by 19 and 22 countries during 2014 and 2015, respectively, with eleven countries reporting stock-outs during both 2014 and 2015. During 2015, 12 of the 22 countries reporting HBR stock-outs were from the African Region and two-thirds of the countries were Gavi-eligible. Information on HBR stock-outs was either not available or not reported by 66 countries (19 were Gavi-eligible) for 2014 and 53 (11 were Gavi-eligible) countries for 2015. Among the 22 countries reporting HBR stock-outs in 2015, 12 (54%) countries reported a single HBR financing source, and nine (41%) countries reported more than one source for HBR financing. The occurrence of HBR stock-outs remains a concern, particularly in Gavi-eligible countries introducing new vaccines where dedicated funding is received for revising and printing new recording tools, including HBRs. Additional attention is needed to understand the root causes for stock-outs and identify solutions to ensure a well-designed, durable HBR is readily available in the right quantity, in the right place at the right time in all countries.

A PI+R Control Scheme Based on Multi-Agent Systems for Economic Dispatch in Isolated BESSs

Battery energy storage systems(BESSs)are widely used in smart grids.However,power consumed by inner impedance and the capacity degradation of each battery unit become particularly severe,which has resulted in an increase in operating costs.The general economic dispatch(ED)algorithm based on marginal cost(MC)consensus is usually a proportional(P)controller,which encounters the defects of slow convergence speed and low control accuracy.In order to solve the distributed ED problem of the isolated BESS network with excellent dynamic and steady-state performance,we attempt to design a proportional integral(PI)controller with a reset mechanism(PI+R)to asymptotically promote MC consensus and total power mismatch towards 0 in this paper.To be frank,the integral term in the PI controller is reset to 0 at an appropriate time when the proportional term undergoes a zero crossing,which accelerates convergence,improves control accuracy,and avoids overshoot.The eigenvalues of the system under a PI+R controller is well analyzed,ensuring the regularity of the system and enabling the reset mechanism.To ensure supply and demand balance within the isolated BESSs,a centralized reset mechanism is introduced,so that the controller is distributed in a flow set and centralized in a jump set.To cope with Zeno behavior and input delay,a dwell time that the system resides in a flow set is given.Based on this,the system with input delays can be reduced to a time-delay free system.Considering the capacity limitation of the battery,a modified MC scheme with PI+R controller is designed.The correctness of the designed scheme is verified through relevant simulations.

Coordinated voltage regulation strategy of OLTC and BESS considering switching delay

When large-scale distributed renewable energy power generation systems are connected to the power grid,the risk of grid voltage fluctuations and exceeding the limit increases greatly.Fortunately,the on-load tap changer(OLTC)can adjust the transformer winding tap to maintain the secondary side voltage within the normal range.However,the inevitable delay in switching transformer taps makes it difficult to respond quickly to voltage fluctuations.Moreover,switching the transformer taps frequently will decrease the service life of OLTC.In order to solve this critical issue,a cooperative voltage regulation strategy applied between the battery energy storage systems(BESSs)and OLTSs.is proposed By adjusting the charge and discharge power of BESSs,the OLTC can frequently switch the transformer taps to achieve rapid voltage regulation.The effectiveness of the proposed coordinated regulation strategy is verified in the IEEE 33 node distribution systems.The simulation results show that the proposed coordinated regulation strategy can stabilize the voltage of the distribution network within a normal range and reduce the frequency of tap switching,as such elongating the service life of the equipment.
