Abstract:

A study on the biodiversity and isolation of freshwater algae from some reservoirs of Mae Rim Campus, Chiang Mai Rajabhat University, Chiang Mai Province, collected algal samples and assessed the water quality at four reservoirs, including Wiang Bua Reservoir, Ma Lang Por Reservoir, Education Auditorium reservoir, and Kru Noi Garden Reservoir. One hundred and six species of algae belonging to 8 phyla were found. The most prominent species were Cylindrospermopsis philippinensis, Trachelomonas volvocina, Peridiniopsis sp., and Coelastrum astroideum, respectively. The overall water quality was categorized as clean according to some physical and chemical parameters by the National Environmental Board of Thailand. However, high BOD values were detected at some sampling points. The algae isolation included 8 isolates, which could be utilized for various purposes in the future, such as biomass, protein, polysaccharide energy, bioactive compounds, antioxidant substances, wastewater treatment, environmental indicators, algal toxins, and phylogenetic studies. All strains were stored at the Centre of Excellence of Biodiversity Research and Implementation for Community, Chiang Mai Rajabhat University, for conservation and future development purposes.

Abstract:

Background: Depression is significant mental health issue among university students and can decrease their ability to succeed academically. While various factors associated with mental health problems have been identified, researchers are increasingly exploring the role of positive mental health, such as character strengths and inner strengths, in relation to mental health problems. Objective: This study aims to build upon previous research by examining the influence of positive mental health on the mediation model of depression among students enrolled at Chiang Mai University. Method/Design: This study will employ an observational and longitudinal study that collects data from undergraduate students at Chiang Mai University during the 2023–2024 academic year. The primary outcome of this study will be depression. In the mediation models, insecure attachment and negative family climate will serve as predictors, while borderline personality symptoms will be the mediator. Positive mental health, including character strengths, inner strengths, and resilience, will be tested for moderation effects on the mediation models. Data will be collected at three intervals, with a three-month gap between each collection period. Discussion and Conclusion: This study will provide insights into the positive and negative mental health outcomes of university students in Chiang Mai. Through comprehensive analysis, this study intends to offer valuable insights into both positive and negative mental health outcomes among university students in Chiang Mai. Moreover, by employing a longitudinal approach, it aims to establish a more robust understanding of the causal relationships between positive mental health, predictors, mediators, and depression. The study’s limitations will also be discussed.

Abstract:

Stress is the problem that is often found in students due to their higher expectations and the changes happening at the personal, social and environmental levels. The main objective of the present study was to develop and analyze the results of a stress management programme conducted for students at Chiang Mai University, Chiang Mai, Thailand. This was quasi-experimental research, conducted according to the one-group plan. The student initiatives included five Chiang Mai University students, selected through purposive sampling after passing the initial screening. They were evaluated by completing the basic information questionnaire of the Suanprung Stress Test-20 (SPST-20) and the Suanprung Stress Test-60 (SPST-60) before and after the programme. The tools used in this study were developed from the conceptual framework according to the Canadian Model of Occupational Performance and Engagement (CMOP-E) model. The researcher used the breathing technique using the diaphragm, and muscle relaxing technique. The concept of emotional awareness was conducted according to the four foundations of mindfulness, and cognitive behavioral therapy (CBT) with group process in occupational therapy. The results of the study revealed that the sample population had significantly lower stress levels after joining the stress management programme. However, it was observed that there was no difference in the susceptibility to stress levels before or after joining the programme. In general, this stress management programme can be undertaken by other students of Chiang Mai University to monitor their stress levels.

Abstract:

Background: Global awareness of ambient air pollution has heightened due to its detrimental impact on health, particularly in regions with elevated PM2.5 levels. Chiang Mai has emerged as an area experiencing the highest PM2.5 levels in Thailand. Objectives: to examine the prevalence of respiratory allergies and assess the impact of air pollution on the health-related quality of life (QoL) among university students in Chiang Mai. Methods: Chiang Mai University (CMU) and Maejo University (MJU) students were recruited. The Global Asthma Network (GAN) questionnaire screened for respiratory allergies (RAs). The disease-specific QoL questionnaire (Rcq-36) was administered twice during low-PM2.5 and high-PM2.5 seasons to evaluate air pollution’s impact on health-related QoL. Those showing potential RAs underwent a skin prick test (SPT) to investigate allergic sensitization. Results: Out of 406 participants, 131 (32%) reported respiratory allergies. Among those undergoing SPT, a high rate (82.54%) had positive results. Across both universities, students reported significantly lower QoL in multiple domains, particularly respiratory, eye, sleep, and emotional well-being, during the high-PM2.5 season. This aligned with their poorer self-reported health on a visual analog scale (VAS; p-value < 0.01). PM2.5 levels significantly impacted social functioning for CMU students (p-value = 0.001) and role limitations for MJU students (p-value < 0.001). Notably, participants without respiratory allergies (non-RAs) were more significantly affected by PM2.5 than RA participants in almost all parameters, despite experiencing fewer baseline symptoms. Conclusions: Respiratory allergies, particularly allergic rhinitis, are prevalent among university students in Chiang Mai. This study underscores the substantial negative impact of ambient air pollution on QoL for both allergic and non-allergic students.

Abstract:

The study was carried out at the Germplasm Centre of Fruit Tree Improvement Programme (GPC-FTIP), Bangladesh Agricultural University, Mymensingh during the period February, 2011 to March, 2012 to find out the effect of shoot bending and fruit thinning on productivity of guava. The treatments of the experiment were four varieties of guava viz., Swarupkathi, BAU piyara-5, Chiang Mai (round) and Chiang Mai (long) and six different management practices viz., (i) control (no shoot bending + no fruit thinning); (ii) shoot bending; (iii) 25% fruit thinning; (iv) 50% fruit thinning; (v) 75% fruit thinning and (vi) 100% fruit thinning. The ages of the plants were 4-5 years. Results revealed that the variety Chiang Mai (round) showed superiority over BAU piyara-5, Chiang Mai (long) and Swarupkathi in respect of fruit yield (15.63 kg/plant) and fruit retention (72.92%) during on-season but during off-season, Swarupkathi showed superiority over Chiang Mai (round), BAU piyara-5 and Chiang Mai (long) in case of number of flowers set per plant (127.44), number of fruits set per plant (75.28), fruit retention (88.66%) and yield (11.78 kg/plant). Different management practices had significant effect on all studied parameters in both seasons. Fifty percent fruit thinning treatment showed the highest fruit yield (20.46 kg/plant) and 75% fruit thinning treatment performed lowest fruit yield (10.06 kg/plant) during on-season but during off-season shoot bending performed highest fruit yield (13.50 kg/plant). Highest fruit retention in both seasons (on-season 89.28% and off-season 90.47%) was observed in 50% fruit thinning treatment. In case of combined effect of variety and different management practices, 50% fruit thinning treatment combined with Chiang Mai (round) produced highest yield (23.15 kg/plant) and fruit retention (92.72%) during on-season, but shoot bending treatment combined with Swarupkathi gave the highest yield (16.06 kg/plant) and 50% fruit thinning combined with Swarupkathi showed highest fruit retention (94.12%) during off-season.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14808 J.

Abstract:

This paper describes an early example of Forest Landscape Restoration (FLR), which resulted from collaboration between a university, local community, and national park authority in the upper Mae Sa Valley, near Chiang Mai City, northern Thailand. Working together, the Hmong community of Ban Mae Sa Mai, Doi Suthep National Park Authority and Chiang Mai University’s Forest Restoration Research Unit (FORRU-CMU) established a chronosequence of trial restoration plots from 1996 to 2013, to test the framework-species method of forest restoration. The project developed successful restoration techniques and gained insights into the factors that influence villagers’ participation in forest restoration. Recovery of forest biomass, carbon storage, structure, biodiversity and ecological functioning exceeded expectations. Villagers appreciated the improved water security resulting from the project, as well as a better relationship with the park authority and increased land security. Recently, however, tree chopping and a breakdown in fire-prevention measures (perhaps symptoms of “project fatigue”) have threatened the sustainability of the plot system. The project demonstrates the importance of a sound scientific basis for forest restoration projects, long-term institutional support, and appropriate funding mechanisms, to achieve sustainability.

Abstract:

For the success of efficient socioeconomic development, it is crucial that budget allocation in higher education is effectively managed, with a clear focus on targeting SDG 4 (Quality Education), which is vital for every country and should be prioritized globally. This research article attempts to assess the socio-economic impact of Chiang Mai University based on the impact of both its expenditure and teaching and training programs on the Northern Thailand economy. Moreover, it also aims to develop the best model to predict the SROI for academic projects before investing the budget for efficient financial management. All the data utilized in this research article come from official organizations such as Chiang Mai University, the Office of the National Economic and Social Development Council (NESDC), and the Provincial Comptroller’s Office of each province in Northern Thailand, with the data collection covering the study period from 2023 to 2025. The key finding is that Chiang Mai University played a significant role in creating a socioeconomic impact on Northern Thailand’s economy, both in the industry sector and the service sector, totaling more than an average of THB 3 billion per year for direct and indirect effects. In addition, every THB 1 million that this university spends can create more than 703 jobs in the agribusiness sector, and, for the same budget spending, it can create 241 jobs in the service sector and 113 jobs in the industry sector, respectively. Technically, for the prediction model to predict the SROI value, it was found that the best model is the Decision Tree model. If the findings of this research can be applied to other universities in Thailand or globally, it would represent a significant initiative in optimizing budget allocation, with a particular emphasis on supporting SDG 4 (Quality Education) as a priority.

Abstract:

Transit-oriented development (TOD) was organized as policies to promote the development of public transportation infrastructure in many countries, including the Thai government. Presently, Thailand is aiming for the growth of the city spreads in each region along with economic growth by stimulating sustainable development, especially in Chiang Mai Province. The purpose of this study was to implement the application of the TOD standard as an analytical tool in the context of Thailand. We adapted TOD standard as an instrument and indicator for physical data collection on areas that have the potential to be developed into TOD stations in Chiang Mai. The TOD standard as a selection tool will be used to score the selected three stations located on the Chiang Mai Red Line Mass Transit System Project that has the potential to develop into TOD. Data collection covers a radius from the stations of 500 meters and 500 – 1000 meters for commercial and residential land use, respectively. The scoring shows that the Airport station is the most potential area, followed by the Chiang Mai Rajabhat University and Nakornping hospital station. The results show that TOD standards had the potential to be used in the context of Thailand to enhance assessment, help in planning and drawing TOD policy for the upcoming station project, and identify specific TOD characteristics that need improvement.

Abstract:

AbstractHeat stress, a regular risk to wheat in the subtropics, is a growing threat in other wheat producing regions as the global temperature rises. This paper reports on three experiments evaluating 49 entries of the 13th High Temperature Wheat Yield Trial (13HTWYT) from the International Centre for Maize and Wheat Improvement (distributed in 2014), with Fang 60 as the local check, at two locations at Chiang Mai, Thailand, a designated representative of the wheat mega-environment 5, in which temperature for the coolest month averages &gt;17.5 °C and the crop is subjected to high temperature for the entire growing season. The wheat was grown in the lowland (elevation 330 m) at Chiang Mai University in (i) sand culture to simulate the condition of non-limiting nutrient and water supply and (ii) in the field and (iii) as an on-farm trial in the highlands (elevation 800 m) at Mae Wang district of Chiang Mai province. Heat tolerance in the wheat germplasm, recently developed for adaptation to high temperature, was indicated by longer pre-heading duration, and the positive correlation between days to heading and grain yield all three experiments. The longer time before heading enabled development of larger spikes that produced more seeds from more and larger spikelets and more competent florets. However, with the number of spikes that was either lower than or similar to Fang 60, none of the recently developed 13HTWYT entries out-yielded the local check from the 1970s.

Abstract:

Thailand has main four dialects spoken as the mother tongue in each region. This article will explore how the Northern dialect is used in Chiang Mai. The data was collected from the daily conversation at four public places: local markets, shopping malls, public transportation, and university cafeterias. The mixed method is the sample's non-participation observation and unstructured interview in the four research areas. The research concept is sociocultural linguistics. The research findings disclose that the local people still speak the Northern dialect in public places in the Chiang Mai centre. It is also found that they use the Northern dialect interspersed with the Bangkok language. The topics of conversation were food, travel, costume, study, entertainment, and sports. These issues were related to the place. All places found a large number of Bangkok language speakers. The findings also imply that the Northern dialect has less used than Bangkok in shopping malls and universities. Chiang Mai is an important tourist city, so people all over the country visit or move to this city with their different languages. It would appear in linguistic phenomena of code-mixing or code-switching between the Northern and Bangkok languages in this area, which should be a different research topic.

Abstract:

This study aimed to validate the “Chiang Mai University Intussusception Failed Score (CMUI)” for intussusception non-operative reduction. Both a 2-year retrospective and a 5-year prospective consecutive review of patients with intussusception were conducted. Data were collected from January 2013 to December 2020. Related retrospective data of a developmental set from two centers from January 2006 to December 2012 were used. Ten prespecified prognostic factors for failed reduction were collected and from these a predictive score was calculated. The actual results of non-operative reduction were collected and set as a reference standard. Altogether, 195 episodes of intussusception were found. Twenty-two patients were excluded due to contraindications; therefore, a total of 173 episodes were included in the validation dataset. The development data set comprised 170 episodes. We found that no statistical significance was found from comparing the areas under the ROC of two datasets (p-value = 0.31), while specificity of the validation set was 93.8% (88.1–97.3). This temporal validation showed a high specificity and a high affinity for prediction of failed reduction as the development dataset despite being in an era of a higher successful reduction rate. The intensive reduction protocols might be introduced among patients with high-risk scores.

Abstract:

Conventional stormwater management may cause long term environmental issues. Fortunately, Water Sensitive Urban Design (WSUD) can manage stormwater more sustainably. However, the design examples of WSUD elements, such as rain gardens within the geographical and cultural context of Thailand are lacking. This study investigated the patterns of rain garden design suitable for urban areas in Chiang Mai and developed examples of rain garden design processes and prototypes in an urban context for Chiang Mai.  This research used the Research by design Method (RDM), which has great potential in bridging the gap between research and application. The researchers selected the site at the Faculty of Agriculture, Chiang Mai University. They designed 2 schematics of rain gardens with local Lanna plants. Then, they compared stormwater capacity with the existing site via the Natural Resources and Conservation Service (NRCS) Curve Number Method. The design results were evaluated by stakeholders and design experts to bridge the gaps between international standards and local contexts.  We found that 1) the west side of the site was most appropriate to develop the pilot project. 2) Both design schematics performed better than the original site. 3) Stakeholders and design experts see the potential of the site, but had concerns regarding its actual performance, maintenance, scale, and safety. This paper offers and provides an example of the rain garden design process which can be used as a baseline for future designs of rain garden and water sensitive urban designs.

Abstract:

Objective The aim of this study was to assess the seroconversion rate and percent inhibition of neutralizing antibodies against the wild-type and Omicron variants of SARS-CoV-2 in patients with solid cancer who received two COVID-19 vaccine doses by comparing chemotherapy and nonchemotherapy groups. Methods This prospective cohort study enrolled 115 cancer patients from Maharaj Nakorn Chiang Mai Hospital, Sriphat Medical Center, Faculty of Medicine, Chiang Mai University, and Chiang Mai Klaimor Hospital, Chiang Mai, Thailand, between August 2021 and February 2022, with data from 91 patients who received two COVID-19 vaccine doses analyzed. Participants received vaccines as part of their personal vaccination programs, including various mRNA and non-mRNA vaccine combinations. Blood samples were collected at baseline, on day 28, and at 6 months post-second dose to assess neutralizing antibodies. The primary outcome was the seroconversion rate against the wild-type and Omicron variants on day 28. Secondary outcomes included seroconversion at 6 months, factors associated with seroconversion, and safety. Results Among the participants, 45% were receiving chemotherapy. On day 28, seroconversion rates were 77% and 62% for the wild-type and Omicron variants, respectively. Chemotherapy did not significantly affect seroconversion rates (p = 0.789 for wild type, p = 0.597 for Omicron). The vaccine type administered was positively correlated with seroconversion, with an adjusted odds ratio (95% confidence interval) of 25.86 (1.39–478.06) for the wild type and 17.38 (3.65–82.66) for the Omicron variant with the primary heterologous vaccine regimen. Grades 1 and 2 adverse events were observed in 34.0% and 19.7% of participants, respectively. Conclusions Despite the lower seroconversion rate against the Omicron variant, no significant difference was observed between the chemotherapy and nonchemotherapy groups. COVID-19 vaccinations demonstrated good tolerability in this cohort. These findings highlight the importance of vaccine safety and immunogenicity in cancer patients and can inform tailored vaccination strategies for this vulnerable population.

Abstract:

Abstract This study aimed to measure tritium (3H) concentrations in Thailand. Nationwide tap water samples were collected in July 2021. Rainwater samples were collected monthly during May–October 2020, April–October 2021, and February–March 2022 in Chonburi province and in Chiang Mai province during July–November 2021, January 2022, and March–June 2022. The measurements of 3H activity concentrations were conducted by Osaka Sangyo University (OSU) and were compared with measurements by the Thailand Institute of Nuclear Technology (TINT). The results from OSU and TINT showed that 3H concentrations in tap water were matched in the ranged from 0.08 ± 0.03 to 0.28 ± 0.04 Bq L−1, while those in rainwater samples collected from Chonburi province and Chiang Mai province are also matched in the ranged from 0.11 ± 0.02 to 0.21 ± 0.03 Bq L−1 and 0.19 ± 0.02 to 0.57 ± 0.04 Bq L−1, respectively. Our measured result suggests that 3H concentration in tap water and rainwater shows a similar relation depending on latitude.

Abstract:

Acinetobacter baumannii has emerged as a significant concern worldwide. The mortality rate of carbapenem-resistant A. baumannii (CRAB) is increasing, especially in the intensive care unit (ICU). Thus, the objective of this study is to compare the efficacy and safety of colistin plus vancomycin for the treatment of critically ill patients with CRAB in Chiang Mai University Hospital. We conducted a retrospective cohort study of critically ill patients in the ICU with CRAB infection who received colistin alone or colistin-vancomycin combination therapy at Chiang Mai University Hospital. A total of 365 critically ill patients met the inclusion criteria. The results in this study showed that after propensity score matching, colistin plus vancomycin showed no significant differences in the 30-day mortality compared to colistin alone. Likewise, for colistin plus vancomycin, compared with colistin therapy alone, there were no significant differences in the clinical response, microbiological response and nephrotoxicity. In conclusion, colistin plus vancomycin was no significant differences in 30-day mortality, clinical response, microbiological response compared to colistin alone for infections due to CRAB. The nephrotoxicity rates were similar for both groups, so colistin combination with vancomycin was not necessary for the management of infection caused by CRAB.

Abstract:

This research aims to investigate motivation that influences Chiang Mai University students’ decision to learn the Korean language. A questionnaire is conducted on the students’ motivation behind their decision to learn the Korean language and their expectations for Korean language learning after graduation. Respondents are 102 students studying Korean as elective courses or minor subjects. The results reveal that the type of motivation that has the highest influence over their Korean language learning is self-motivation, and they are also motivated by curriculum and institutes, the ‘Korean Wave’ and the society, defined as social motivation, respectively. Their highest post-graduation expectation for Korean language learning is the ability to converse fluently with Korean people, while the ability to understand Korean songs/dramas/variety programs, the ability to understand Korean society and culture, the ability to get a job using the Korean language, the opportunity to study in South Korea and the opportunity to have new friends are the next highest expectations successively.

Abstract:

Introduction: Global medical and healthcare education systems are increasingly adopting team-based learning (TBL). TBL is an interactive teaching programme for improving the performance, clinical knowledge, and communication skills of students. The aim of this study is to report the learning experience and satisfaction of participants with the TBL programme in the preclinical years of the Faculty of Medicine, Chiang Mai University. Methods: Following the implementation of TBL in the academic year 2022, we asked 387 preclinical medical students, consisting of 222 Year 2 and 165 Year 3 medical students who attended the TBL class to voluntarily complete a self-assessment survey. Results: Overall, 95.35% of the students were satisfied with the structure of the TBL course and agreed to attend the next TBL class. The overall satisfaction score was also high (4.44 ± 0.627). In addition, the students strongly agreed that the TBL programme improved their communication skills (4.50 ± 0.796), learning improvement (4.41 ± 0.781), and enthusiasm for learning (4.46 ± 0.795). Conclusion: The survey findings indicated that students valued TBL-based learning since it enabled them to collaborate and embrace learning while perhaps enhancing their study abilities. However, since this is a pilot study, further investigations are warranted. Keywords: Team-based learning, Small group interaction, Medical education, Implementation

Abstract:

This study conducted a project to assess carbon sequestration in the forest area of Chiang Mai Rajabhat University, Mae Rim Campus, covering a total area of approximately 5,600 rai, with about 75% consisting of dry dipterocarp forest. The Sentinel-2 satellite data from 2019 to 2023 were used to analyze and classify forest density using the Normalized Difference Vegetation Index (NDVI). It was classified into four NDVI levels: highest, high, moderate, and low. Then, eight sample plots were distributed across all density levels to collect field data on tree species, number of trees, height, and diameter. The biomass and carbon sequestration in the sample plots showed a strong correlation with vegetation density, with the highest average correlation in February, particularly on February 13, 2023, showing the highest correlation coefficient of 0.817. This relationship is described by the equation y=78.601x‒25.726, indicating that this model is effective for estimating carbon sequestration. The analysis revealed that the area with the highest NDVI level of dry dipterocarp forest had the highest above-ground carbon sequestration rate of 16.25 tons per rai, whereas the forest with the lowest NDVI level had an above-ground carbon sequestration rate of 0.21 tons per rai. In total, the above-ground carbon sequestration for the trees amounted to 50,907.35 tons. This preliminary assessment serves as a promising foundation for future efforts the conservation and restoration of the university’s forest area, contributing to sustainable strategies for mitigating global warming.

Abstract:

Introduction: Pulmonary hypertension (PHT) is an emerging complication of myeloproliferative neoplasms (MPNs). The aim of this study was to determine the prevalence and risk factors of high echocardiographic probability of PHT according to 2015 The Joint Task Force for the Diagnosis and Treatment of Pulmonary Hypertension of the European Society of Cardiology (ESC) and the European Respiratory Society (ERS) Guideline. The echocardiographic probability of PHT was assessed by peak tricuspid regurgitation velocity (TRV max) and echocardiographic signs suggesting PHT. Methods: This was a cross-sectional study conducted in Chiang-Mai University Hospital during January 2019 and July 2019. Patients aged 18 years or older with Philadelphia chromosome negative MPNs including polycythemia vera (PV), essential thrombocythemia (ET), and myelofibrosis (MF) were eligible after obtaining informed consents. Patients who were known to have a preexisting PHT from any causes were excluded. All enrolled patients had an echocardiography performed by a cardiologist for evaluating the probability of PHT according to 2015 ESC/ERS guideline. Primary outcome of the study was the prevalence of MPNs patients who had high echocardiographic probability of PHT. Secondary outcomes were risk factor of high echocardiographic probability of PHT. Results: A total of 23 patients with a median age of 64 years (range 45-87) were enrolled. There were 14 PV (60.9%), 8 ET (34.8%), 1 MF (4.3%) patients included. There were13 male patients (56.5%). The most common driver mutation was JAK2V617F mutation (19 patients, 82.6%). Common co-morbid diseases were hypertension (26.1%), combined hypertension and dyslipidemia (13%), and combined hypertension and diabetes (8.7%), respectively. The majority of patients (73.9%) did not have history of thrombosis. However, 57.2% and 62.5% of PV and ET patients were classified as high risk of thrombosis. Twenty two patients (95.6%) received both antiplatelets and cytoreductive agents with 9 patients (39.1%) also underwent phlebotomy. Hydroxyurea was only cytoreductive drug prescribed in this study. The median time from diagnosis to echocardiogram evaluation was 66 months (range 9-6,242 months). Median (range) hemoglobin was 11.7 g/dl (9.7-16.8), median white blood cells count was 7.5x109/L (4.0-24.1), and median platelet count was 374x109/L (171-931). No patient with high echocardiographic probability of PHT was detected. One patient (4.3%) patient had intermediate probability and 22 (95.7%) patients had low probability. The median value of TRV max was 2.42 m/s (range 1.93-2.90). Conclusions: No MPNs patients (0/23) with high echocardiographic probability of PHT detected in this study. Further study with higher number of patients is warrant for determine the prevalence of PHT in Thai MPN patients. Table Disclosures No relevant conflicts of interest to declare.

Abstract:

The linear accelerator system of the PBP-CMU Electron Linac Laboratory has been designed with the aim of generating free-electron lasers (FELs) in the mid-infrared (MIR) and terahertz (THz) regions. The quality of the radiation is strongly dependent on the properties of the electron beam. Among the important beam parameters, the electron beam energy and energy spread are particularly important. To accurately measure the electron beam energy, the first dipole magnet in the bunch compressor system and the downstream screen station are employed as an energy spectrometer. The A Space Charge Tracking Algorithm (ASTRA) software is used for the design and optimization of this system. Simulation results demonstrate that the developed spectrometer is capable of accurately measuring the energy within the 5–25 MeV range. The screen station system is designed and constructed to have the ability to capture a beam size with a resolution of 0.1 mm per pixel. This resolution is achieved with a screen-to-camera distance of 1.2 m, which proves sufficient for precise energy measurement. The systematic error in energy measurement is found to be less than 10%, with a minimum energy spread of 0.4% achievable when the horizontal beam size remains below 3 mm.

Abstract:

Objectives: This study aims to explore the levels of overall and occupational stress, correlation between overall and occupational stress, factors affecting overall and occupational stress, and stress management strategies among dentists who graduated from Chiang Mai University. Methods: 2,650 dentists who graduated from Chiang Mai University between 1983 and 2020 and are now working in Thailand were the subject of this study. Between May and September 2021, 2,466 dentists were provided online surveys that included the Suanprung Stress Test-20, Work Stress Inventory for Dentists, and Stress-coping strategy checklist. 588 respondents filled out the surveys (response rate was 23.8%). With the level of significance set at 0.05, descriptive and analytical statistics were used to examine the data using SPSS. Results: 78% of respondents had moderate to high level of overall stress, 84.9% had low to normal level of occupational stress. There was a positive correlation between overall and occupational stress (rs=0.686, p<0.001). ‘age’, ‘having underlying disease’, and ‘financial status’ were the factors which significantly resulted in different overall stress scores (p<0.05). ‘hobbies’ had the highest rating for stress coping (87.6%), followed by ‘resting’ (79.7%) and ‘eating’ (68.4%). Conclusions: The majority of dentists had normal levels of occupational stress, moderate to high levels of overall stress, and occupational stress significantly correlated with overall stress. There were a few factors that affect overall stress after adjusting for influences of the confounding variables. And there were a variety of stress coping strategies that dentists used for stress management. The findings of this study could be useful for strategic planning to prevent and resolve dentists' stress issues in the future.

Objectives: This study aims to explore the levels of overall and occupational stress, correlation between overall and occupational stress, factors affecting overall and occupational stress, and stress management strategies among dentists who graduated from Chiang Mai University. Methods: 2,650 dentists who graduated from Chiang Mai University between 1983 and 2020 and are now working in Thailand were the subject of this study. Between May and September 2021, 2,466 dentists were provided online surveys that included the Suanprung Stress Test-20, Work Stress Inventory for Dentists, and Stress-coping strategy checklist. 588 respondents filled out the surveys (response rate was 23.8%). With the level of significance set at 0.05, descriptive and analytical statistics were used to examine the data using SPSS. Results: 78% of respondents had moderate to high level of overall stress, 84.9% had low to normal level of occupational stress. There was a positive correlation between overall and occupational stress (rs=0.686, p<0.001). ‘age’, ‘having underlying disease’, and ‘financial status’ were the factors which significantly resulted in different overall stress scores (p<0.05). ‘hobbies’ had the highest rating for stress coping (87.6%), followed by ‘resting’ (79.7%) and ‘eating’ (68.4%). Conclusions: The majority of dentists had normal levels of occupational stress, moderate to high levels of overall stress, and occupational stress significantly correlated with overall stress. There were a few factors that affect overall stress after adjusting for influences of the confounding variables. And there were a variety of stress coping strategies that dentists used for stress management. The findings of this study could be useful for strategic planning to prevent and resolve dentists' stress issues in the future.

Abstract:

Chiang Mai, an important City in the northern part of Thailand, has been changed rapidly because ofurban development. This causes the increase of population and changes in land use, especially the rapiddecrease of agricultural lands which, as a result, affects on the environment and quality of life of people in thecity. The objectives of this research study were to investigate the potential of agricultural lands, the attitude ofthe agriculturist in the area on agricultural lands, and to give suggestions on how to conserve the agriculturallands sustainably by means of field survey, collected secondary data and interview 1,000 agriculturist withการศึกษาศักยภาพแหล่งเกษตรกรรม เพื่อการอนุรักษ์ให้เป็นพื้นที่สีเขียวของเมืองเชียงใหม่The Potential of Agricultural Lands for Conservation of Green Areain Chiang Mai Cityปรัชมาศ ลัญชานนท์Pradchamas Lanchanonคณะสถาปัตยกรรมศาสตร์และการออกแบบสิ่งแวดล้อม มหาวิทยาลัยแม่โจ้ เชียงใหม่ 50290Faculty of Architecture and Environmental Design, Maejo University, Chiang Mai 50290, ThailandE-mail: lanchanon@gmail.com116 JARS 10(2). 2013questionnaires. The potential of agricultural lands was then analyzed by Potential Surface Analysis (PSA) andquantitative data was analyzed in terms of percentage and mean. It was found that the northern and easternplains were appropriate for farming, and the southern plain for horticulture. As for economics and social aspects,it revealed that there were sufficient supporting market for farm products, but the problems was high productioncost and low production price. However, the agriculturists want to conserve their agricultural lands, but they didnot have younger generations to do farming. To conserve the farm lands sustainably, it consisted of the landuse control for conservation of agricultural lands, tax measures, investment funds or cooperative, producttransformed promotion, the development of central markets for agricultural products, the implantation ofland-use awareness to the people and younger generations, the knowledge and information dissimilation tothe agriculturists and agricultural grouping.

Abstract:

    This research aims to perform the techno-economic feasibility of the applied hybrid biomass stove to produce hot water for serving Child Development Center (CDC) in Omkoi District, Chiang Mai, Thailand. The hot water generated from the stove could help to decrease LPG usage and enhance household economics. Many activities in CDC (i.e., children showering during the winter season, cloth washing, and utensils cleaning among others) require hot water to prevent the contamination of harmful germs which could cause many diseases such as diarrhea in young children. Presently, Asian Development College for Community Economy and Technology, Chiang Mai Rajabhat University (adiCET) has installed the hybrid stove to the in Omkoi district. The biomass stove could generate 90 °C hot water using plant/agriculture waste as the fuel. However, the economical parameters (i.e., Payback Period, Net Present Value and Internal Rate of Return) could strengthen the technology. The results from this study could be used as one of the guidelines for policymakers to design the appropriate programs for enhancing the CDC using the waste-to-energy concept.
