The COVID-19 pandemic altered consumption behavior and waste generation patterns in major cities worldwide. Quantitative studies in Bangkok remain limited. This study aims to assess the impact of COVID-19 on per-capita waste generation in Bangkok using Interrupted Time Series (ITS) analysis, comparing pre-, during-, and post-pandemic periods. Monthly waste data from 50 Bangkok districts (October 2010–September 2024, n = 175 months) were analyzed using segmented linear regression with Newey-West HAC standard errors (maxlags = 12). Three intervention points were specified: plastic bag ban (January 2020), COVID-19 onset (February 2020), and 4-plastic ban (January 2022). Analysis was performed in Python 3.12. Mean per-capita waste declined from 1.874 kg/person/day pre-COVID to 1.537 kg/person/day during the pandemic (−18.0%). ITS analysis revealed an immediate level decrease of −0.230 kg/person/day attributable to COVID-19 (p = 0.078), with a subsequent increasing trend of +0.105 kg/person/month (p = 0.104). COVID-19 significantly altered Bangkok's waste generation patterns with an initial decline followed by recovery. These findings have implications for public health emergency preparedness and waste management planning.

DIGITAL HEALTH KNOWLEDGE AND ITS ASSOCIATED FACTORS AMONG PRE-ELDERLY PERSONNEL AT A UNIVERSITY IN NORTHEASTERN THAILAND: A CROSS-SECTIONAL STUDY

Tue, 30 Jun 2026 00:00:00 +0700

The rapid growth of the aging population has increased the importance of digital health knowledge in supporting effective health management, particularly among pre-elderly individuals. This study aimed to assess the level of digital health knowledge and examine its association with personal factors and digital health–related technology use behaviors among pre-elderly personnel at a university in northeastern Thailand.

A cross-sectional survey was conducted among 50 personnel aged 45–59 years, selected using a stratified random sampling method. Data were collected using a structured questionnaire covering personal characteristics, digital health–related technology use behaviors, and digital health knowledge. Descriptive statistics were used to summarize the data, and Chi-square test or Fisher’s exact test was applied to examine associations.

The results showed that most participants had a moderate level of digital health knowledge (46.0%), followed by low (34.0%) and high levels (20.0%). Age and job category were significantly associated with digital health knowledge (p<0.05), with younger participants and academic staff demonstrating higher levels of knowledge. In contrast, digital health–related technology use behaviors were not significantly associated with knowledge level.

These findings suggest that digital health knowledge is influenced by demographic factors rather than the frequency of technology use. Therefore, targeted interventions focusing on older age groups and support staff, as well as enhancing the ability to critically evaluate digital health information, are essential to improve digital health knowledge among pre-elderly populations.

Ekkachai Sribunrueang — Tue, 30 Jun 2026 00:00:00 +0700

The Development of a Krabi Krabong Learning Model Using Cooperative Active Learning to Enhance Academic Achievement of Mathayom 1 Students The objectives of this research were: 1) to develop a Krabi Krabong (Thai martial art) learning model using Cooperative Active Learning for Mathayom 1 (Grade 7) students; 2) to compare the academic achievement in Krabi Krabong using the developed model; 3) to compare the students' agility level before and after the Cooperative Active Learning; and 4) to study the students' satisfaction with the developed learning model. The target group consisted of 80 Mathayom 1 students at Sriboonyanon School during the first semester of the 2024 academic year, selected by purposive sampling. The research instruments included: 1) developed lesson plans based on the model; 2) an academic achievement test; and 3) a satisfaction evaluation form. Data were analyzed using content analysis, mean (), percentage, standard deviation (S.D.) and t-test statistics. The findings were as follows:The developed Krabi Krabong learning model using Cooperative Active Learning for Mathayom 1 students achieved an efficiency of 82.67/84.63, which was higher than the pre-set criterion of 80/80.The experimental group's mean academic achievement score was 16.95, while the control group's mean score was 16.63. The mean score of the experimental group was significantly higher than the control group at the .05 level. For agility, the post-test mean of the experimental group was 12.27 seconds, and the control group's mean was 12.95 seconds. The mean agility of the experimental group was significantly higher (better) than the control group at the .05 level. However, the mean agility of the experimental group between the pre-test (13.16 seconds) and post-test (12.27 seconds) was not significantly different at the .05 level. The overall satisfaction of the students with the Krabi Krabong learning management using the Cooperative Active Learning model was at a high level.

EFFECTS OF STATIC STRETCHING AND PASSIVE STRETCHING WITH ASSISTANCE ON FLEXIBILITY IN HIGH SCHOOL BASKETBALL PLAYERS

Tue, 30 Jun 2026 00:00:00 +0700

The purpose of this study was to investigate and compare the effects of static stretching and passive stretching on flexibility in high school basketball players following a six-week training program. The participants were 26 male basketball players aged 16–18 years from a secondary school in Udon Thani Province, Thailand. Participants were purposively selected and assigned into two groups: a static stretching group (n = 13) and a passive stretching group assisted by a partner (n = 13).

Flexibility was assessed using the sit-and-reach test to evaluate hamstring and lower back flexibility and the back extension test to assess trunk flexibility. Both groups participated in supervised stretching sessions three times per week for six weeks, with each session lasting approximately 45 minutes. Paired samples t-tests were used to analyze within-group changes, and independent samples t-tests were used to compare post-test differences between groups. Statistical significance was set at p < .05.

The results showed that both static stretching and passive stretching significantly improved flexibility within groups after the intervention (p < .001). However, between-group comparisons revealed that the passive stretching group demonstrated significantly greater improvements than the static stretching group in both sit-and-reach and back extension performance (p < .001).

This study aims to determine the relationships among social support, self-concept, and self-efficacy, and the motivation to learn physical education among boarding and regular school students. Specifically, this study analyzes: (1) the correlation of social support with motivation to learn physical education, (2) the correlation of self-concept with motivation to learn physical education, (3) the correlation of self-efficacy with motivation to learn physical education, and (4) the correlation of social support, self-concept, and self-efficacy simultaneously with motivation to learn physical education in both groups of students. This study uses a quantitative, cross-sectional method. The study population comprised 1,408 students from two schools: SMA Negeri 1 Comal and MAN Pemalang. The sampling technique used was purposive sampling, yielding a sample of 228 students. The research instruments included the Physical Self-Description Questionnaire–Short to measure self-concept, the General Self-Efficacy Scale to measure self-efficacy, and a questionnaire on motivation to learn physical education. Data analysis was carried out using descriptive statistics, normality tests, Pearson correlation tests, and multiple regression analyses with the JASP software. The results of this study indicate that social support, self-concept, and self-efficacy are related to physical education learning motivation in both boarding and regular students, both partially and simultaneously. However, the strength of the relationship and the contribution of these variables tend to be better in the regular student group than in the boarding student group. This study concludes that psychological and social factors play an important role in shaping motivation for physical education learning. These findings extend previous studies by emphasizing differences in characteristics between student groups and recommend that physical education practitioners pay attention to social support, strengthening self-concept, and increasing self-efficacy in the learning process.
