Purpose: The purpose of this study was to evaluate the effects of a Tai-Chi exercise program on subjective health and physiological function index. Methods: This study was designed as non-equivalent control group pretestposttest research. Eighteen women in each group completed the posttest with an attendance rate of 78.3 % after 12 weeks. The Tai Chi exercise program was provided two times a week over three months for the experimental group, but no program for the control group. A questionnaire was used for subjective health index, which consisted of Korean-WOMAC Index for joint stiffness, K-HAQ for physical disability, EQ-5D for quality of life and perceived health status, and CES-D for depression. To measure the effect on the physiological function index, femoral muscle strength, shoulder joint and back flexibility were measured. Results: All variables except left anterior femoral muscle strength had significant homogeneity between the two groups. There were statistically significant differences between the experimental group and the control group in joint stiffness (t=-2.165, p=.03), physical disability (t=-2.231, p=.038), EQ-5D index (t=3.783, p=.001), perceived health status (t=-2.349, p=.025) and femoral posterior muscle strength (t=2.487, p=.038). Conclusion: The Tai-Chi exercise program was beneficial for women with arthritis in rural communities.

A prefabricated composite hollow slab with perforated I-beams was suggested for the replacement of deteriorated concrete decks or the construction of new composite bridges with long-span slabs. Composite slabs with embedded I-beams have considerably higher stiffness and strength. For the application of prefabricated composite slabs to bridges, joints between slabs should satisfy the requirements of the ultimate limit state and the serviceability limit state. In this paper, three types of the detail for loop joints were selected and their structural performance in terms of strength and crack control was investigated through static tests on continuous composite slabs. A main parameter was the detail of the joint, such as an ordinary loop joint and loop joint with additional reinforcements. Even though there was no connection of the steel beams at the joints, the loop joints showed good performance in ultimate strength. In terms of crack control, the loop joint with additional reinforcements showed better performance. In ultimate limit state, the continuous composite slabs showed good moment redistribution and ductility.

Purpose: This study was conducted to determine the effects of Tai-Chi exercise and self-help management program applying laughter therapy in patients with osteoarthritis. Methods: This quasi-experimental study recruited a sample of 61 patients with osteoarthritis (experimental group: 30, control group: 31) through the community healthcare centers located in Seoul and Kyung Gi area. The primary outcome measures included symptoms of osteoarthritis, basic physical performance, fatigue, and depression assessed before and after the study. The data were analyzed using SPSSWIN V. 12.0. Results: At the end of the six-week intervention, left shoulder flexibility (t=2.011, p=.049), 6m walking speed (t=3.639, p=.001), and right balance (t=-2.30, p=.025) were significantly improved in the control group. Fatigue (t=3.012, p=.004), stiffness (t=2,093, p=.041), right shoulder flexibility (t=2.138, p=.037), right balance (t=-2.065, p=.043), and 6m walking speed (t=2.683, p=.009) were significantly improved in the experimental group. Conclusion: A twice a week, 6-week tai-chi exercise self-help management program applying laughter therapy is effective in decreasing fatigue and stiffness. Osteoarthritis is one of common chronic diseases that the patients should be required to continue self management for the rest of their life. Therefore, there is a need to develop the more effective self-help management program and nursing intervention to motivate them to maintain their own self-help management.

This paper introduces a new hybrid structural connection joint that combines shear walls with section steel beams, fundamentally resolving the construction complexity issue of requiring pre-embedded connectors in the connection between shear walls and steel beams. Initially, a quasi-static loading scheme with load-deformation dual control was employed to conduct low-cycle repeated loading experiments on five new connection joints. Data was acquired using displacement and strain gauges to compare the energy dissipation coefficients of each specimen. The destruction process of the new connection joints was meticulously observed and recorded, delineating it into three stages. Hysteresis curves and skeleton curves of the joint specimens were plotted based on experimental results, summarizing the energy dissipation performance of the joints. It's noteworthy that the addition of shear walls led to an approximate 17% increase in the energy dissipation coefficient. The energy dissipation coefficients of dog-bone-shaped connection joints with shear walls and cover plates reached 2.043 and 2.059, respectively, exhibiting the most comprehensive hysteresis curves. Additionally, the impact of laminated steel plates covering composite concrete floors on the stiffness of semi-rigid joint ends under excessive stretching should not be disregarded. A comparison with finite element analysis results yielded an error of merely 2.2%, offering substantial evidence for the wide-ranging application prospects of this innovative joint in seismic performance.

This study aimed to investigate the relationship between dietary acidity load and clinical symptoms in the patients with rheumatoid arthritis (RA). This case-control study examined 55 patients with RA and 215 healthy individuals in a Ravansar non-communicable diseases (RaNCDs) cohort study, Iran. Participants' food intakes were assessed using a validated food frequency questionnaire. The dietary acidity was calculated using potential renal acid load (PRAL), net endogenous acid production (NEAP), and dietary acid load (DAL) scores. The patients with RA were identified based on the self-reporting, medications history, and the approval of the cohort center physician following patients' examination. The odds ratio (OR) of joint stiffness in fully adjusted model was greater in the upper median of dietary acidity than in the lower median (PRAL: odds ratio [OR], 1.18; 95% confidence interval [CI], 0.59-2.36), but there was no statistically significant difference. The OR of joint pain in the upper median of dietary acidity was less than in the lower median in fully adjusted model (PRAL: OR, 0.70; 95% CI, 0.46-1.29), but the difference was not statistically significant. After adjusting potential confounders, people in the upper median of dietary acidity had a higher OR of developing RA than those in the lower median (PRAL: OR, 1.39; 95% CI, 0.70-2.76); however, it was not statistically significant. There was not any statistically significant relationship among dietary acidity and the odds of joint pain, joint stiffness, and developing RA.
