https://so04.tci-thaijo.org/index.php/jstpcru/article/view/277884
<p>This quasi-experimental research aimed to investigate the effectiveness of a safe sex education program focused on open-minded conversations between adults and their children. The sample comprised 30 adults caring for children aged 11-19 years in Bueng Sam Phan sub-district, Bueng Sam Phan district, Phetchabun province, selected through purposive sampling. The research instrument was the safe sex education program, which included five learning activities: 1) Ice-breaking and introduction, 2) Enhancing parental confidence, 3) Emotional awareness and the "Understanding Each Other" station, 4) Reflecting on the past and life timeline, and 5) Creative communication and evaluation. Data collection instruments included: 1) a questionnaire assessing attitudes, knowledge, and skills in communicating about safe sex, and 2) a mental health assessment form. Data were collected between June and July 2024 and analysed using percentages, means, standard deviations, and Paired t-tests. The findings revealed a statistically significant difference (p<.05) in the mean scores of attitudes, knowledge, safe sex communication skills, and mental health after participation in the program compared to before the intervention. Specifically, significant improvements were observed in: attitudes towards understanding contemporary adolescents (t=2.76), knowledge about reproductive health (t=9.10), knowledge about safe sex (t=11.88), self-emotion management skills (t=12.04), communication skills with adolescents (t=3.26), skills in communicating about sex with adolescents (t=5.75), and mental health (t=6.02)</p> <p><span class="fontstyle0"> </span></p>Rattiya Wonglappanichkhajornwithaya prapalertLaoo SinhachotsukpatKruawan Kamfoo

https://so04.tci-thaijo.org/index.php/jstpcru/article/view/276802
<p>The application of pesticides in agricultural practices, particularly in rice cultivation, has significant impacts on freshwater ecosystems and poses risks to the survival of various aquatic organisms. This study aimed to evaluate the acute toxicity of the pesticide diazinon on juvenile Nile tilapia (<em>Oreochromis niloticus</em>) and freshwater prawns (<em>Macrobrachium lanchesteri</em>). A static bioassay was conducted to determine the concentration causing 50% mortality within 96 hours (96hr-LC<sub>50</sub>), and the data were analyzed using probit analysis. The results revealed that the 96hr-LC<sub>50</sub> values for juvenile Nile tilapia and freshwater prawns were 14.67 and 1.39 ppm, respectively. These findings can be utilized to establish safe concentration thresholds of diazinon in natural water bodies, providing essential data for ecological risk assessment and supporting the formulation of environmentally sustainable pesticide management strategies in agriculture.</p> <p><span class="fontstyle0"> </span></p>Kittichai ChantimaSukanya KantakWichuda Jindatham

https://so04.tci-thaijo.org/index.php/jstpcru/article/view/280155
<p> <span class="fontstyle0">Solid Waste Management is a critical issue that all sectors must urgently address. This study<br />aimed to examine the behaviors and factors related to household solid waste management among residents in Ban Noen Subdistrict Administrative Organization, Lom Kao District, Phetchabun Province. A total of 317 households were selected using stratified random sampling. <br />Data were collected by questionnaires and analyzed using descriptive statistics. Inferential statistics, including the Chi-Square test (<span class="fontstyle2">χ</span>²) and Pearson’s Product Moment Correlation Coefficient (r), were used to test hypotheses, with the significance level set at 0.05. The results showed that the residents in Ban Noen Subdistrict Administrative Organization<br />had a high level of household solid waste management behavior (M = 3.96, SD = .45). Personal<br />factors such as education level and occupation were significantly associated with household solid waste management behavior at the 0. 05 significance level. Attitudes toward household solid waste management and participation in household solid waste management were positively correlated with the waste management behavior at a moderate level, with statistical significance (r = 0. 334, p < 0. 001 and r = 0. 481, p < 0. 001, respectively) . Therefore, continuous public campaigns and information dissemination should be promoted to encourage community<br />participation in waste management for more effective and sustainable outcomes. <br /></span></p>Punnapa WonglakhonSaroj NakjuThavorn Maton

2025-06-242025-06-2451ุ6172Factors Associated with Rabies Prevention Behavior Among Residents in Lom Kao Subdistrict Municipality, Lom Kao District, Phetchabun Province
https://so04.tci-thaijo.org/index.php/jstpcru/article/view/280197
<p> Rabies is a serious zoonotic disease that continues to be a significant public health problem in many areas around the world. It affects lives and causes fear and anxiety in society. This study is a cross-sectional descriptive research aimed at studying behaviors and factors associated with rabies prevention behaviors among the population in Lom Kao Subdistrict Municipality, Lom Kao District, Phetchabun Province. The sample consisted of 135 pet-owning residents selected through simple random sampling. Data were collected using questionnaires and analyzed using descriptive statistics and inferential statistics, including Chi-square analysis and Pearson’s correlation coefficient, with the statistical significance level set at 0.05. The results revealed that the overall rabies prevention behavior among the participants was at a high level ( = 3.87, S.D. = 0.63), while the overall motivation for rabies prevention was at a moderate level ( = 3.64, S.D. = 0.38). Factors found to be significantly associated with rabies prevention behavior included age (r = 0.201, p-value = 0.019), occupation (p-value = 0.033), history of animal bites, scratches, or licks (p-value = 0.011), access to rabies-related information (p-value = 0.026), and motivation for rabies prevention (r = 0.599, p-value < 0.001). The findings of this study will lead to the development of strategies and guidelines to promote rabies prevention behaviors by local administrative organizations, public health agencies, livestock departments, as well as community networks, to effectively and appropriately prevent rabies in accordance with the community context.</p>Thanaporn SrichanSaroj Nakju

2025-06-262025-06-26517384On The Exponential Diophantine Equation (4n-1)^x +63^y =z^2 where (4n-1) is Prime
https://so04.tci-thaijo.org/index.php/jstpcru/article/view/277859
<p>In this paper, we study the exponential Diophantine equation (4n-1)^x +63^y =z^2 where (4n-1) is prime. We found that all non-negative integer solutions are of the following (n,x,y,z)\epsilon \left\{ (1,1,0,2),(1,4,1,12),(8,2,1,32)\right\}\cup \left\{(n,0,1,8)\right\}\cup \left\{ \left ( \frac{63^m+1}{2},1,2m,63^m+1 \right )\right\}, where n,m are positive integers x,y and z are non-negative integers. In the proof, we apply reasonably Catalan's conjecture and various theorems concerning the congruence to obtain the solution.</p>Napatsakorn KasiphanJirapong PuangmalaiWanwisa Puangmalai
