최근에 넓은 공간이 요구되는 건축물에서는 칸막이 벽과 같은 비구조재의 사용이 감소됨으로써 감쇠효과가 크게 줄어들고 있으며 고강도재료의 사용으로 바닥판 구조물이 유연화, 장경간화 되어가고 있다. 대형집회공간, 쇼핑몰, 사무실 등과 같이 장경간 건축물에서는 사람의 움직임에 의하여 과도한 진동이 발생할 수 있으며 이러한 진동은 건축물의 사용성을 크게 저하시키는 원인이 되고 있다. 바닥판 진동의 주요 진동원 중의 하나가 보행하중이다. 보행하중을 받는 구조물의 진동해석에 있어서 보행하중을 적용하는 일반적인 방법은 한 절점에 보행하중을 연속적으로 가하거나 주기하중으로 이상화된 동적하중을 가하는 것이다. 그러나 이러한 방법은 보행의 이동효과를 고려할 수 없다. 본 논문에서는 실제 바닥판 구조물의 고유진동수와 감쇠비를 평가하였으며 예제 구조물의 효율적인 진동해석을 위하여 보행하중을 적용하였다.

Purpose This study aims to propose a framework for safety in domestic walking tourism, which defines the scope and type of safety information for tourists. Also, the framework provides a systematic classification for safety information in walking tourism. As the importance of safety in walking tourism due to the frequent occurrence of crimes and unexpected accidents increases, it is necessary to provide tourists with safety information on walking courses rapidly and systematically. However, most administrators (e.g., local governments) have mainly focused on providing tour information on walking courses through Internet websites or mobile apps, overlooking the safety issue. Besides, there is a lack of understanding of safety not only in walking tourism but also in the whole tourism industry. Design/methodology/approach This study proposes the framework that covers all possible safety-related information in walking tourism. Furthermore, to validate its availability, this study analyzes eight major platforms which offer tour information to tourists by applying the framework. Findings The major findings of this study are as follows. First, all platforms considered in this study do not provide any information on tourism safety, focusing on the provision of tour information. Second, three platforms currently provide an SOS function which means post-safety information. That is, no safety information is provided to prevent safety issues in advance. Finally, despite the increase of social concerns, all platforms do not provide safety information on public order and diseases in the social disaster classification as well as environmental pollution in the natural disaster classification. The details and implications of the findings are presented.

PURPOSE: The purpose of this study was to investigate which treadmill walking training mode is more effective strategy for improving pulmonary function of persons with chronic stroke. METHODS: Twenty-one chronic stroke patients were allocated and randomly to an experimental group (treadmill training with randomized speed control, n=11) and a control group (treadmill training without speed change, n=10). All participants received 30 minutes of neurodevelopmental treatment. In addition, the two groups performed treadmill training for 20 minutes each time with or without speed change. Speed change was applied 40%, 50%, 60%, 70% of Heart Rate Reserve. All the exercise programs lasted six weeks, with five times per week. Pulmonary function was assessed before and after exercise program by using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV). RESULTS: In the both groups, FEV1 was significantly increased after training (p<.05). Compared to the control group, the experimental group showed 11.9% larger amount of change (p<.05). In the experimental group, FVC and MVV were significantly increased after training (9.9%, 7.6%, respectively) (p<.05). But in the control group, there was no significant difference in the FVC and MVV after training. CONCLUSION: Treadmill training with randomized speed control will be a better positive rehabilitation program than treadmill training without speed change to improve pulmonary function in persons with chronic stroke.

Objective : The purpose of this study was to investigate the theta on the components of ground reaction force according to the ground conditions during gait. Method : Six healthy women(mean age: 22 yrs, mean height: $166.14{\pm}2.51cm$, mean body weights: $56.61{\pm}4.58kg$) participated in this study. The medial-lateral GRF(Fx 1), anterior-posterior GRF(Fy 1, Fy 2), vertical GRF(Fz 1, Fz 2, Fz 3), and impact loading rate were determined from time function and frequency domain. Also, GRF theta were time function and forces. Results : Fx 1, Fy 1 and Fy 2 of stair descending showed significant statistically higher forces than that of level walking, and ascending. Fz 1 of stairs descending showed significant statistically higher forces than that of level walking and stairs ascending(theta $88.62^{\circ}$). Also, Fz 2 of level walking showed significant statistically higher forces than that of stairs ascending and descending(theta $65.78^{\circ}$). Fz 3 of stairs ascending showed significant statistically higher forces than that of level walking and stairs descending($65.26^{\circ}$). Impact loading rate of stairs descending showed significant statistically higher forces than that of level and ascending walking. The GRF showed similar correlation with GRF theta(r=.603) according to the ground conditions during gait. Conclusion : These results suggest that the GRF theta can be used in conjunction with a gait characteristics, prediction of loading rate and dynamic stability.

PURPOSE: This study aimed to investigate the effects of pressure sense perception training (PSPT) on various surfaces on the somatosensory system, balance, and walking ability in chronic stroke patients. METHODS: Thirty patients with stroke participated in this study and were randomly assigned to one of three groups; group 1 received the general physical therapy and the PSPT on a stable surface, group 2 received the general physical therapy and the PSPT on an unstable surface, and group 3 received the general physical therapy alone. Participants in group 1 and group 2 underwent 30 min/session, 3 days per week, for 4 weeks. Pressure error (PE) was used to evaluate changes of proprioception. The Balancia, Functional reach test (FRT), and Timed Up and Go (TUG) were used to assess the balance ability, and the 10m Walking Test (10-MWT) was used to assess walking ability. RESULTS: Experimental groups (group 1 and group 2) showed significant differences in PE, FRT, TUG, and 10-MWT compared to the control group (p <0.05). Group 2 (PSPT on an unstable surface) was significantly different in PE, FRT, and 10-MWT from group 1 (p <0.05). No significant differences were observed for other measures. CONCLUSION: Pressure sense perception training on an unstable surface might be a significantly more effective method for improving somatosensory function, balance, and walking ability, than PSPT on a stable surface.

PURPOSE: The purpose of this study was to determine the effects of arm training in standing position on balance and walking ability in chronic stroke patients. METHODS: Sixteen chronic stroke patients were allocated equally and randomly to an experimental group (n=8) or a control group (n=8). All participants received 60 minutes of comprehensive rehabilitation treatment, the experimental group additionally received an arm training in standing position for 30 minutes, while the control group additionally performed a treadmill training for 30 minutes. These 30-minute training sessions were held three times per week for six weeks. Upper extremity function was assessed using Fugle-Meyer motor assessment function upper extremity (FMA-UE), balance was assessed using Berg balance scale (BBS), and walking ability (gait speed, cadence, step length, and double limb support period) was assessed using the GAITRite system. RESULTS: Improvement on all outcome measures was identified from pre-to-post intervention for both groups (p<.05). Post-intervention, there was a significant between-group difference on BBS, gait speed, cadence, step length, and double limp support period (p<.05). The experimental group exhibited greater improvement in the BBS (p=.01; z=-2.48), gait speed (p=.01; z=-3.26), cadence (p=.02; z=-2.31), step length (p=.01; z=-3.36), and double limb support period (p=.03; z=-2.84) compared to the control group. CONCLUSION: The findings of this study suggest that arm training in standing position may be beneficial for improving balance and walking ability of patients with chronic stroke.

Purpose: The purpose of this study was to demonstrate the effects of a stepwise proprioceptive neuromuscular facilitation (PNF) pattern therapy in weightbearing positions on the balance and walking functions of a patient with subacute stroke. Methods: The patient was a 78-year-old man with right post-stroke hemiparesis who had decreased balance and gait function. During the baseline and withdrawal phases, no intervention was applied; however, in the intervention phase, the patient received a stepwise PNF pattern therapy in weight-bearing positions. Results: During the intervention phase, the LOS improved by 296.51% (from $2482.13mm^2$ to $626mm^2$), and walking speed improved by 18.70% (from 0.75 m/s to 0.64 m/s). The LOS and 10MWT values appeared to be clinically significantly improved after the intervention. In addition, the scores of the BBS and ABC scales improved by 100% (from 36 points to 18 points) and 56.52% (from 720 points to 460 points), respectively. Conclusion: These findings suggest that a stepwise PNF pattern therapy may be helpful in enhancing the balance and walking function of a patient with subacute stroke. Further studies are required to validate the results of this study.

Objectives: Physical inactivity is the fourth leading global risk factor for mortality, followed by obesity. The combination of these risk factors is associated with non-communicable diseases, impaired physical function, and declining mental function. The World Health Organization recommends physical activity to reduce the mortality rate. Thus, this study examined the effects on anthropometric measurements of a 12-week walking program for elderly people in Samarahan, Sarawak, Malaysia with a 7000-step goal and weekly group walking activities. Methods: A quasi-experimental study was conducted involving 109 elderly people with a body mass index (BMI) ≥25.0 kg/m². BMI, body composition, and average daily steps were measured at baseline, 6 weeks, and 12 weeks. Data were analyzed using SPSS version 26.0, and repeated-measures analysis of variance with the paired t-test for post-hoc analysis was conducted. Results: In total, 48 participants in the intervention group and 61 participants in the control group completed the study. A significant interaction was found between time and group. The post-hoc analysis showed a significant difference between pre-intervention and post-intervention (within the intervention group). The post-intervention analysis revealed an increase in the mean number of daily steps by 3571.59, with decreases in body weight (-2.20 kg), BMI (-0.94 kg/m²), body fat percentage (-3.52%), visceral fat percentage (-1.29%) and waist circumference (-2.91 cm). Skeletal muscle percentage also showed a significant increase (1.67%). Conclusions: A 12-week walking program combining a 7000-step goals with weekly group walking activities had a significant effect on the anthropometric measurements of previously inactive and overweight/obese elderly people.
