The current research develops and tests the theory that beliefs in economic mobility are affected by social capital at the community level, especially for low-income individuals. Integrating concepts from social capital and perceived economic mobility (PEM), this research hypothesizes that members of disadvantaged groups (vs. members of advantaged groups) are more likely to adjust their PEM depending on the social capital at the community level. Using archival data, multilevel analysis is employed to examine whether individual- or community-level social capital increases PEM and the extent to which income moderates this relationship. Consistent with our hypotheses, social capital at the community level is significantly associated with PEM and this relationship is stronger for low-income (vs. high-income) earners. Study 1 shows that individuals in communities with high levels of social relations and participation are more likely to have higher PEM than those in communities with lower levels. Study 2 replicates this finding with a similar dependent variable: negative prospects. Further, the PEM-enhancing and negative prospects-decreasing effects of community-level social capital are consistently stronger for low-income (vs. high-income) earners. This study extends the investigation of PEM and social capital by suggesting social capital as a possible antecedent of PEM.

Objectives: The objective of this study was to demonstrate the effects of community-based social distancing interventions after the first coronavirus disease 2019 (COVID-19) case in Turkey on the course of the pandemic and to determine the number of prevented cases. Methods: In this ecological study, the interventions implemented in response to the first COVID-19 cases in Turkey were evaluated and the effect of the interventions was demonstrated by calculating the effective reproduction number (R_t) of severe acute respiratory syndrome coro navirus 2 (SARS-CoV-2) when people complied with community-based social distancing rules. Results: Google mobility scores decreased by an average of 36.33±22.41 points (range, 2.60 to 84.80) and a median of 43.80 points (interquartile range [IQR], 24.90 to 50.25). The interventions caused the calculated R_t to decrease to 1.88 (95% confidence interval, 1.87 to 1.89). The median growth rate was 19.90% (IQR, 10.90 to 53.90). A positive correlation was found between Google mobility data and R_t (r=0.783; p<0.001). The expected number of cases if the growth rate had not changed was predicted according to Google mobility categories, and it was estimated to be 1 381 922 in total. Thus, community-based interventions were estimated to have prevented 1 299 593 people from being infected. Conclusions: Community-based social distancing interventions significantly decreased the R_t of COVID-19 by reducing human mobility, and thereby prevented many people from becoming infected. Another important result of this study is that it shows health policymakers that data on human mobility in the community obtained via mobile phones can be a guide for measures to be taken.

Mobility models are invaluable for determining the performance of routing protocols in opportunistic networks. The movement of nodes has a significant influence on the topological structure and data transmission in networks. In this paper, we propose a new mobility model called the campus-based community mobility model (CBCNM) that closely reflects the daily life pattern of students on a real campus. Consequent on a discovery that the pause time of nodes in their community follows a power law distribution, instead of a classical exponential distribution, we abstract the semi-Markov model from the movement of the campus nodes and analyze its rationality. Then, using the semi-Markov algorithm to switch the movement of the nodes between communities, we infer the steady-state probability of node distribution at random time points. We verified the proposed CBCNM via numerical simulations and compared all the parameters with real data in several aspects, including the nodes' contact and inter-contact times. The results obtained indicate that the CBCNM is highly adaptive to an actual campus scenario. Further, the model is shown to have better data transmission network performance than conventional models under various routing strategies.

The limited walking ability after a stroke restricts a patient's independent mobility at home and in the community. It also brings about significant social handicaps. Therefore, it is necessary to improve walking ability in community-dwelling persons with stroke. The purpose of this study was to evaluate the effectiveness of gait training and muscle strengthening exercise of lower extremities in persons with chronic stroke. Nineteen community-dwelling individuals with stroke participated in this program. The exercise program lasted for seven weeks, with a 1-hour program twice per week, and it consisted of balance training, gait training, and strengthening of lower extremities. The outcome of the program was assessed by the gait speed, Wisconsin Gait Scale (WGS), Berg Balance Scale (BBS), and Stroke Impact Scale (SIS). Significant effects were found for the WGS, BBS, and mobility and hand function domain of the SIS (p<.05). It was found that short-term gait training exercise could improve quality of gait, balance, and mobility. Therefore, a more effective exercise program is required for community-based persons with stroke.

Objective : This study aimed to systematically examine studies on the life-space mobility in community-dwelling elderly and analyze and summarize the research trends. Methods : The Embase and PubMed databases were searched for articles on the life-space mobility of community-dwelling elderly published between January 2010 and January 2020. Based on the selection and exclusion criteria of the 335 articles, a total of 27 articles were finally selected and analyzed. Results : As a results, 11 (40.7%) cohort studies had evidence level II. This study showed that the participants in the studies were healthy elderly (81.5%), and the University of Alabama Life-Space Assessment (UAB-LSA) used the most participants (88.9%). Of the foci of the 27 finally selected studies, 8 (29.6%) were physical, 8 (29.6%) were psychosocial, 6 (22.2%) were cognitive, and 2 (7.4%) were social, and 3 (11.1%) were others. The life-space mobility of the elderly needs to be analyzed from a multidimensional point of view, and not based on a single factor such as the physical, cognitive, psychosocial, or social. Conclusion : The results of this study are expected to verify causality through the study of life-space mobility for the elderly staying in various communities and provide future directions for the study on the mobility of the elderly's and the development of community-based intervention programs.

Objectives: This study was conducted to develop the Mobility to Participation Assessment Scale for Stroke (MPASS) and assess its content validity, internal consistency, inter-rater and intra-rater reliability, and convergent validity in people with stroke living in the community. Methods: The MPASS was developed using published data on mobility-related activity and participation timing in elderly individuals, and then reviewed by community physical therapists. Content validity was established by reaching a consensus of experienced physical therapists in a focus group. The MPASS was scored for 32 participants with stroke (mean age 61.75±4.92 years) by 3 individual testers. Reliability was examined using the intraclass correlation coefficient (ICC), internal consistency using the Cronbach alpha coefficient (α), and convergent validity using the Pearson correlation coefficient (r) to compare the MPASS to the Modified Rivermead Mobility Index as a referent test of mobility. Results: The MPASS consists of 8 items, and its scoring system provides information on the ability of people with stroke to reach a movement level enabling them to live in society, including interactions with other people and safe living in the community. The interrater and intra-rater reliability were excellent (ICC, 0.948; 95% confidence interval [CI], 0.893 to 0.982 and ICC, 0.967; 95% CI, 0.933 to 0.989, respectively). Internal consistency was good (α=0.877). The convergent validity was moderate (r=0.646; p<0.001). Conclusions: The newly developed MPASS showed acceptable construct validity and high reliability. The MPASS is suitable for use in people with stroke, especially those who have been discharged and live in the community with the ability to initiate sitting.

Objective : The purpose of study is to validate the clinical utility and usability of the Korean version of the Life Space Assessment(K-LSA) which is an assessment tool of community mobility of older adults. Methods : Surveys on the clinical utility and usability of the K-LSA are carried out with a total of aoaa60 occupational and physical therapists. The surveys included the multiple choice questions on the clinical utility and open questions on the usability. Responses to multiple questions are post processed by frequency analysis and technical statistics, and responses to the open questions are categorized by common factors in each questions. Results : Average value of clinical utility ranges from 3.6 to 4.0 with positive responses of 'fair (3 point)', 'agree (4 point)' and 'strongly agree (5 point)' being 95~100%. Average value for clinical usability ranges from 3.6 to 4 with positive answers of 'fair (3 point)', 'easy (4 point)' and 'very easy (5 point)' being 88.3~100%. Additionally out of open-type questions of clinical usability, it was pointed out that the concept of 'neighborhood' for the life space level 3 and 4 is unclear. Conclusion : The current study and research outcomes showed that the K-LSA is a validated tool in Korean health care system for the clinical utility and usability in measuring community mobility, and that it is straightforward in practical use. It will help clinicians and therapists promote the social participation of older adults, and set an intervention goal for enhancing community mobility. It will further help clinicians and researchers in education and research for medical intervention and goal-setting.

Purpose: This study was conducted in order to investigate the effects of an aerobic exercise program on mobility, fall efficacy, balance, and stress in the elderly at senior centers. Methods: This research was conducted as a quasi-experimental pretest and posttest control and experimental comparison study. The subjects were 41 senior residents (Exp.=18, Cont.=23) who aged above 65 at senior centers in S City. The period of time for data collection and intervention was from August 25 to December 5, 2008. Results: Mobility (t=-3.10, p<.01) in the experimental group were significantly higher than those in the control group without an aerobic exercise program. However, fall efficacy (t=1.28, p=.207), balance (t=-.53, p=.602; t=.36, p=.723), stress (t=-1.32, p=.199) in the experimental group was not significantly higher than that in the control group. Conclusion: These findings confirmed that aerobic exercise programs make a contribution to improving mobility in the elderly at senior centers.

PURPOSE: Proprioceptive Neuromuscular Facilitation (PNF) has been shown to improve body function and activity/participation in people with functional dysfunctions. This study evaluates if active exercise using theraband in PNF pattern may induce similar benefits as exercise using manual PNF pattern performed by physiotherapists on promoting mobility, balance and fear of fall in community-dwelling elderly. METHODS: Twenty-three community-dwelling elderly with independent activities of daily living were recruited and randomly allocated into either PNF group - exercise in PNF pattern by trained physiotherapists or Theraband-PNF (T-PNF) group - exercise using theraband in PNF pattern, for an hour, twice weekly for 4 weeks. Functional outcomes such as Timed Up and Go test, Elderly Mobility Scale, Berg balance scale, functional reach and subjective measures including fear of fall (FOF) scale, bodily pain in visual analogue scale were measured pre and post-program. RESULTS: Twenty-one participants completed the program. PNF group demonstrated significant within-group improvements in all subjective measures and objective measures. Similar within-group improvements were demonstrated in all outcome measures except FOFS in T-PNF group. However, no between-group differences were found in any of the outcome measures. CONCLUSION: Comparable improvements in functional outcomes in community dwelling elderly were demonstrated in both groups. As manual PNF exercise traditionally need clinicians' contact and feedback on patient which limit the training to be carried out extensively in community setting. The current findings suggest that exercise using theraband in PNF pattern is feasible to be adopted as self-practice exercise for community-dwelling elderly to induce beneficial effects on functional outcomes.

This study investigated the general characteristics of mobility disadvantaged persons with disabilities, and to suggest implications to ensure personal mobility with the greatest possible independence for the physically disabled in community. The survey questionnaire included the categories as follows: the general characteristics of the participants, the status of outing and mobility, usage of low-floor buses & taxi for the disabled, service improvement, and mobile support center. Data collected from 219 with physical disabilities were analyzed for this purpose by using descriptive statistics. The study results showed that 54.6% of the total tended to go out everyday, and 17.0% rarely. 53.4% could go out without any assistance, and the major obstacles not to go out were stairs and inconvenience of public transportation. 26.9% used low-floor buses, and 71.1% preferred to use taxi for the disabled. The average waiting time for the usage of low-flow buses and taxi was 66.57 minute and 42.65 minute, separately. 78.7% insisted that the function of mobile support center in the community should be expanded, whereas only 49.8% recognized the role of mobile support center. Based on the study results, the researchers suggested to facilitate access by persons with disabilities to mobility aids, and to improve the actual state of pedestrian environment. In addition, the function of mobile support center should be expanded to help the mobility disadvantaged persons live independently in community, thereby contributing to the promotion of their quality of life.
