Objectives This study aims to analyze the effectiveness of manual therapy for the treatment of plantar fasciitis by reviewing existing randomized controlled trials. Specifically, it seeks to identify various manual therapy techniques and evaluate their applicability in clinical settings. Methods The study reviewed literature from six databases (PubMed, the Cochrane Library, China National Knowledge Infrastructure, ScienceON, Research Information Sharing Service, Korean studies Information Service System) up to April 2024. Studies were selected based on criteria including randomized controlled trials involving manual therapy for plantar fasciitis. Results An analysis of ten studies involving 714 patients revealed the use of techniques such as joint mobilization, muscle relaxation, and pressure point techniques. Manual therapy was found to be more effective in reducing pain than both extracorporeal shock wave therapy and routine physical therapy alone. However, caution is needed in generalizing these results due to the limited number of studies analyzed. No significant adverse effects were reported. Conclusions Manual therapy demonstrates potential as an effective treatment for plantar fasciitis, offering benefits in pain management and functional recovery. However, further high-quality randomized controlled trials are necessary to strengthen the clinical evidence and establish standardized treatment protocols.

Purpose: The purpose of this study was to develop a respiratory infection prevention program for the rural elderly in the post-coronavirus disease 2019 (COVID-19) era. Methods: The Delphi method was used to validate the contents of the program. Two rounds of Delphi surveys and one individual interview were conducted on four subjects and 16 categories with nine experts. Content validity was calculated using the content validity ratio (CVR) and coefficient of variation (CV). Results: This study verified the content validity of the existing program components, such as respiratory infection prevention characteristics, cough etiquette, correct hand washing, oral hygiene, correct tooth brushing, and exercise by walking. The study comprised 28 categories covering seven subjects, including the provision of knowledge and information about COVID-19, environmental management for respiratory infection prevention, and exercise training for immunity enhancement. Conclusion: This Delphi study examined the respiratory infection prevention program that was redesigned for the post-COVID-19 era and confirmed the validity of the educational contents. The findings of this study suggest that the program can be used practically for the prevention of respiratory infection among the rural elderly.

Purpose : Stroke patients exhibit abnormal walking patterns such as slow walking speed and asymmetrical walking values. The recovery of symmetrical walking in the stance phase using a treadmill means improvements in walking speed and asymmetrical walking. The purpose of this research was to investigate the effect of unilateral step treadmill training (USTT) on gait speed and the recovery of symmetrical walking in chronic stroke patients. Methods : Fifteen patients (11 men and 4 women) with chronic stroke participated in this study. The 10-meter walk test (10MWT) and GAITRite system were used to determine the intervention-related changes in gait speed and symmetrical walking values such as non-paretic step length (NSL), non-paretic step time (NST), paretic single-support time (PSST), step length asymmetry (SLA), and step time asymmetry (STA) after USTT. All participants completed USTT and underwent measurements at 3 different times: at pretest, posttest, and the follow-up test. Repeated-measures analysis of variance was used to compare walking speed and asymmetrical walking values. The statistical significance level was set at p<.05. Results : Walking speed by 10MWT (p<.05) showed significant improvements after USTT as follows: at pretest and posttest (p<.05), posttest and follow-up test (p<.05), and pretest and follow-up test (p<.05). Recovery of symmetrical walking patterns such as NSL (p<.05), NST (p<.05), and SLA (p<.05) were observed after USTT. However, no significant improvements were found in PSST (p>.05) and STA (p>.05) in symmetrical gait. Conclusion : This study suggests that USTT may have a positive effect on walking speed and symmetrical walking patterns in chronic stroke patients. Thus, this study contributes to the existing knowledge about the usefulness of USTT for the effective management of patients with chronic stroke. Further studies are needed to generalize these findings.

This paper studies VPBL(Various PBL) models, applies them to classes, and analyzes results so that students of various majors can design and implement problems according to the characteristics of their majors in order to improve problem solving in education. VPBL performs the process of designing and implementing problems that reflect the characteristics of the major by applying constraints to the professor's programming language. The professor performs mini_class in the process of solving the designed problem and then shares it throughout. VPBL model apply results, The traditional teaching method was 3.51 points and the application of the VPBL model was 4.52 points, and "interaction, understanding of learning contents, and acquiring knowledge related to curriculum" were improved. In addition, VPBL has the advantage of expanding the learning range in the solving process as it is based on various problem solving, which has the effect of expanding the learning range compared to existing class models. Research on the expanded application of various SW liberal education in the future is required.

The most important identity of public library is local public goods that guarantee access and use of knowledge and information of local residents. To justify this, the library must create an optimal lighting environment. Particularly, since the perception rate of information through vision is over 80%, it is necessary to secure proper illuminance. This study measured the illuminance level of public libraries in Daegu. Based on the results, this study suggested a desirable illuminance level for each space and proposed plans to secure and maintain proper illuminance(prospective revision of the KS A 3011, setting the illuminance range for each space of the local government, replacing the existing lighting fixtures with LED, enhance supervision of lighting management, establishment of basic principles for proper lighting and detailed plans for each space of the library, investigation and reflection on users' complaints and satisfaction, etc.)

Nowadays, the amount of image data increase explosively. To manage the large amount of image data efficiently, high-dimensional index structures are necessary. However, as my knowledge none of existing DBMSs supports high-dimensional index structures as access methods of DBMSs. In this paper, we design and implement CIR-Tree as a access method for retrieving image data effectively on the MiDAS-III that is the storage subsystem of the BADA-III. The implemented CIR-Tree manager shows much better retrieval performance than sequential search in performance evaluation.
