Stein is an epiphytic orchid native to Thailand, found in restricted areas and classified as near threatened. Therefore, studying the reproductive patterns of this orchid species is essential for supporting conservation efforts and enhancing its population. This study aimed to investigate these reproductive patterns of the orchid within a greenhouse established as part of the Lady's Slipper Orchid Conservation Project at Doi Inthanon, Chiang Mai province. The research was conducted from December 2019 to February 2020. Data on greenhouse environmental conditions, morphological characteristics of <em>P. villosum</em>, and five pollination methods; four hand pollination methods (self-pollination, cross-pollination, emasculation, and spontaneous autogamy) and natural pollination were recorded. Insect pollinators were observed for 160 hours. The results showed that floral morphology was influenced by pollination patterns. Self-pollination (40%) and cross pollination (30%) exhibited higher fruit-setting rates compared to natural pollination (20%). One species each of <em>Stomoxys</em> sp., <em>Episyrphus</em> sp., and <em>Betasyrphus</em> sp. were observed. These findings highlight the need for further research on efficient pollination pattern to increase populations of this endangered orchid species, ultimately contributing to the conservation of the lady’s slipper orchids in Thailand.</p>2024-12-29T00:00:00+07:00Copyright (c) 2024 Journal of Science and Technology Phetchabun Rajabhat Universityhttps://so04.tci-thaijo.org/index.php/jstpcru/article/view/274602Participatory solid waste management in the San Khong Noi community, Chiang Rai Municipality2024-10-09T09:40:26+07:00Satian Chuntachunta7@gmail.comSutthiporn Piamsuwannakitms_sutthiporn@crru.ac.thSuruswadee Nanglaems_sutthiporn@crru.ac.thArunee Inthepms_sutthiporn@crru.ac.thSupattanee Piamsuwannakitms_sutthiporn@crru.ac.thSamran Chuamuangphanms_sutthiporn@crru.ac.thSurin Thongkhamms_sutthiporn@crru.ac.th<p style="margin: 0in; margin-bottom: .0001pt; text-align: justify; text-justify: inter-cluster; text-indent: .5in;"><span style="font-size: 16.0pt; font-family: 'TH SarabunPSK',sans-serif;">The purposes of this research were to study the conditions, factors, and participatory solid waste management in the San Khong Noi community, Chiang Rai Municipality, and distill the lessons of participatory waste management in the community. We conducted the research using a qualitative method, gathering data from household representatives among 50 and 15 community committees. The research tools used were SWOT and TOWS analyses, the CIPP model, guide interview structure, and focus group discussion. We gathered the data using content analysis and synthesis, then composed it into a descriptive research report. The study revealed that San Khong Noi is an urban community with a garbage problem. Garbage from various activities has increased in both households and communities, contributing to the problem. Factors that support success in community solid waste management include community leaders, community committees, village health volunteers, and villagers working together to manage solid waste using the 3R principles: reduce, reuse, recycle, and 5Kor. The 5Kor components, which include a group, fund, rules, activities, and committee, work together to create an efficient community solid waste management model, such as a <span lang="TH">“</span>Recyclable Waste Bank, etc. The Chiang Rai Municipality and the Chiang Rai Provincial Office have come together to support the budget and implement a concrete waste management plan.

The samples were bought from five shops in Muang District, Sakon Nakorn province. The reaction between boric acid and curcumin yielded a rosocyanine compound (red color), absorbing light at a wavelength of 550 nm. From the result, the standard curve between absorbance and boric acid concentration (0.02, 0.04, 0.08, 0.16 and 0.24 µg/mL) was linear, with an R<sup>2</sup> value of 0.9964 and a standard deviation ranging from 0.002-0.005. The results from pickled mangoes (five shops) indicated that the amount of boric acid ranged from 0.572 to 1.15 µg/g. The samples from three shops contained boric acid levels of about 0.5 µg/g, which was lower than the samples from two shops (1.15 and 0.803 µg/g). A comparison of the present results with the criteria from the Ministry of Public Health Issue 391 B.E. 2561 suggested that all pickled mangoes from these five shops were unsafe for consumers because the presence of boric acid (a prohibited substance) exceeded the criteria.</p>2024-12-29T00:00:00+07:00Copyright (c) 2024 Journal of Science and Technology Phetchabun Rajabhat Universityhttps://so04.tci-thaijo.org/index.php/jstpcru/article/view/274992A study of the geometric shapes between players on the passing success of youth Football players2024-10-07T09:54:43+07:00Sarayut Pantiansarayut.p@lawasri.tru.ac.th<p>This study aims to analyze and identify the geometric shapes between players that influence the success of passing among youth football players, utilizing Pearson’s Correlation Coefficient and Linear Regression Analysis. The research employed player tracking technology and video processing with Python to analyze the movements and playing patterns of the athletes. The findings revealed that triangular shapes have a significant positive correlation with passing success (r = 0.67, p = 0.003), with the highest success rate of 72.5%. Additionally, Linear Regression Analysis indicated that each unit increase in the frequency of triangles leads to a 0.45% increase in passing success rate. Quadrilateral and pentagon shapes showed decreasing success rates, with quadrilaterals having a moderate correlation (r = 0.45, p = 0.012) and pentagons <br />a lower correlation (r = 0.30, p = 0.080). The analysis suggests that positioning players in triangular formations is the most effective strategy for enhancing passing success in youth football.</p>2024-12-29T00:00:00+07:00Copyright (c) 2024 Journal of Science and Technology Phetchabun Rajabhat Universityhttps://so04.tci-thaijo.org/index.php/jstpcru/article/view/273248The promotion of child development using Line chatbot and machine learning2024-12-02T04:30:03+07:00Kanokporn ChangruenngamThanayut.cha@crru.ac.thVanichaya WanchaitanawongThanayut.cha@crru.ac.thJumrus KlinhnuThanayut.cha@crru.ac.thNarongsak SrisomThanayut.cha@crru.ac.thSuruswadee NanglaeThanayut.cha@crru.ac.thThanayut changruenngamthanayut.cha@crru.ac.th<p>Promoting the development of children from birth to 5 years is essential because children's brains develop at the fastest rate. The brain creates billions of neural connections every second. Appropriate stimulation such as touching, talking and playing help promote brain cell connections, giving children a strong learning foundation. however, challenges such as overcrowding at hospitals and the COVID-19 pandemic have made it difficult for parents to access child development promotion services. This study utilizes the Early Childhood Development Assessment and Promotion Manual to evaluate the development of young children in five areas: Gross Motor (GM), Fine Motor (FM), Receptive Language (RL), Expressive Language (EL), and Personal and Social (PS). The objective of this research is to develop a chatbot on the LINE platform to facilitate child development promotion, aiming to alleviate the aforementioned challenges. The study employs Random Forest models and Generalized Linear Models (GLMs), trained using child development data collected from 2014 to 2019, with the RapidMiner Studio Educational Version 9.5.001 software. The performance of these models was evaluated based on Accuracy and Area Under the Curve (AUC). The findings indicate that the development of a chatbot for child development promotion significantly enhances the ease, convenience, and speed of parental child development assessments. The chatbot also enables real-time data collection. Furthermore, the results reveal that the Generalized Linear Model outperforms the Random Forest model in predictive efficiency.</p>2024-12-29T00:00:00+07:00Copyright (c) 2024 Journal of Science and Technology Phetchabun Rajabhat Universityhttps://so04.tci-thaijo.org/index.php/jstpcru/article/view/274670 Nutritional Status and Health Behaviors 3E2S of People: A Case Study of Kaeng Hin Village, Wang Prachop Subdistrict, Mueang District, Tak Province2024-11-19T13:53:28+07:00Juthathip Thunkamwasoontara2556@gmail.comWachakorn Nopnarinwasoontara2556@gmail.comWasoontara Ratanopaswasoontara2556@gmail.com<p>This descriptive research aimed to study nutritional status and health behaviors 3E2S of people: a case study of Kaeng Hin Village, Wang Prachop Subdistrict, Mueang District, Tak Province.
