It is necessary to study effect of those activities on the environment and biological qualities in this area. The relationships between aquatic environment parameters (AEP) and phytoplankton density in this estuary were investigated using the canonical correspondence analysis (CCA) method. The AEP was classified for two main seasons, monsoon (July-October) and summer seasons (November-April) by the unweighted pair group method with arithmetic mean analysis with similarity scores of 98.79% and 98.18%. The inter-change period was May classified by CCA score at 99.54%. Two divisions, 11 families, 14 genera, and 17 species of phytoplankton were recorded in this study. The division Chromophyta showed the highest density (74.96%) followed by Cyanophyta (26.04%). Similar to AEP analysis, phytoplankton was classified as monsoon or summer species with CCA similarity scores of 74.28% and 55.00%, respectively. Phosphate, conductivity, silicates, pH, and temperature showed correlations to phytoplankton density with CCA variable scores of 0.84, 0.75, 0.74, 0.72, and 0.71, respectively. This study reveals that the density of <em>Triceratium</em> sp., <em>Rhizosolenia</em> sp., <em>Odontella</em> sp., and <em>Cyclotella stylorum</em> diatoms might be used as bio-indicators for the fluctuations of salinity and pH in this estuary. </p> Kieattisak Yokseng Patchara Pedpradab Copyright (c) 2022 Life Sciences and Environment Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2022-09-08 2022-09-08 23 2 271 282 10.14456/lsej.2022.21 OPTIMUM CONDITIONS OF USING BIO-EXTRACT FROM URINE WITH VINASSE AND MANURE AFFECTING YIELDS OF MARIGOLD https://ph01.tci-thaijo.org/index.php/psru/article/view/245836 <p>Factors affecting yields of marigold using fermented bio-extract from urine with vinasse and animal manure were analyzed by response surface methodology with a central composite design. The various concentrations of each bio-extract concentration and volume of bio-extract were investigated. The results revealed that the optimum conditions were bio-extract of 16.38 %v/v and volume of bio-extract of 40.13 mL/plant. Under the optimal conditions, the maximum flower number, flower size and flower fresh weight were found at 7.84 flowers/plant, <br />5.90 cm and 7.34 g/flower, respectively. The confirmation experiment under the optimal condition showed the flower number of 8.00 flowers/plant, flower size of 5.98 cm and flower fresh weight of 7.38 g/flower. The result was close to the predicted values by linear regression.</p> Chakkrit Sreela-or Punnada Tharungsri Supawadee Yamkong Patthanun Kotam Prapasiri Jaipong Copyright (c) 2022 Life Sciences and Environment Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2022-09-08 2022-09-08 23 2 283 296 10.14456/lsej.2022.22 EFFECTS OF CASSAVA BASED INTERCROPS WITH THAI-MELON ON WEED CONTROL AND LAND USE EFFICIENCY https://ph01.tci-thaijo.org/index.php/psru/article/view/246834 <p>The purpose of this study was to study the effect of cassava monoculture and cassava-Thai melon intercrop and land use efficiency. The experimental plan was randomized complete block design (RCBD) three treatments, with three replications: mono cassava, cassava-Thai melon intercrop and mono Thai melon. The results showed that the cassava-Thai melon intercrop had no effect on height, leaf weight and fresh root weight. In addition, it was found that in all treatments, there were nine types of weeds. The densities of weeds in monoculture were significantly higher than that of intercrops. The results of Thai melon found that intercrops had a longer stem length than that of mono Thai melon, but the number of branches per plant in intercrops was less than mono Thai melonIn the intercropping, fruit weight was not statistically different from that of monoculture. However, cassava-Thai melon intercrop had higher land equivalent ratio (LER) than monoculture. In conclusion, Thai melons can be intercrop ped in cassava without affecting cassava yield and Thai melon yield. It also helps to mulch the soil in the early stages of cassava growth and reduce the number of weeds.</p> Wimonsiri Sehawong Sayan Subepang Copyright (c) 2022 Life Sciences and Environment Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2022-09-09 2022-09-09 23 2 297 305 10.14456/lsej.2022.23 BINARY LOGISTIC REGRESSION ANALYSIS FOR THE RELATIONSHIP OF AN UNDERGRADUATE STUDY CHOICE AT PHIBUNSONGKHRAM RAJABHAT UNIVERSITY WITH VARIOUS FACTORS https://ph01.tci-thaijo.org/index.php/psru/article/view/246648 <p>Currently, the relationship studying of various factors affecting the choice of bachelor's degree in the university is a matter of interest from universities because of the continually rising competition in the higher education market.

MERRILL) IN PHO PRATHAP CHANG SUB-DISTRICT, PHO PRATHAP CHANG DISTRICT, PHICHIT PROVINCE https://ph01.tci-thaijo.org/index.php/psru/article/view/248483 <p>This study analyzed and assessed the heavy metal contaminations and bioaccumulation factors including lead, copper and zinc in soil and three citrus maxima varieties, namely Khaw-Taengkwa, Tha-Khoi and Thong-Dee in Pho Prathap Chang Sub-district, Pho Prathap Chang District, Phichit Province. Soil and Citrus maxima samples were collected in the same garden by random sampling of 10 gardens of each variety, with a total of 30 gardens (Three soil samplings under canopy were collected from 15 citrus maxima trees per garden and citrus maxima samplings were collected 2 samples per garden). Lead, copper and zinc contents in soil and citrus maxima samples were analyzed by using the Atomic Absorption Spectrophotometer (AAS). The results showed that the averages of lead copper and zinc contents in garden’s soils of all citrus maxima varieties were within the soil quality standards set by the Department of Land Development. For heavy metal contaminations in citrus maximaes, lead contents in Khaw-Taengkwa, Tha-Khoi and Thong-Dee varieties were averaged 5.83±0.94, 6.40±3.56 and 9.95±2.84 mg/kg, exceeding the WHO permissible limits with 65%, 55% and 75%, respectively. <br />The copper contents exceeded the standard limit only in Tha-Khoi variety with 25%. The amount of zinc contamination was within the standard limit in all citrus maxima varieties. The bio-accumulation factor (BAF) of lead, copper and zinc in all three citrus maxima varieties were less than 1, which were considered these citrus maximaes have a low ability to transport these heavy metals from the soil to accumulate in citrus maxima fruits.</p> Suphinya Phiromchom Suphinya Junrak Piyada Wachirawongsakorn Copyright (c) 2022 Life Sciences and Environment Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2022-09-09 2022-09-09 23 2 393 408 10.14456/lsej.2022.30 THE EFFECT OF WEATHER ON PM2.5 IN BANGKOK AREA AND BANGKOK METROPOLITAN REGION USING MACHINE LEARNING https://ph01.tci-thaijo.org/index.php/psru/article/view/248189 <p>The purpose of this study was to investigate the effects of five weather variables (temperature, precipitation, relative humidity, wind speed, and STP) on the particulate matter 2.5 (PM2.5) concentrations and to apply a long short-term memory model (LSTM) in order to predict PM2.5 concentrations from these weather variables. We used the PM2.5 data from the Pollution Control Department (Thai Ministry of Natural Resources and the Environment) and weather variables data from the Global Surface Summary of the Day (GSOD) in the area of study (Bangkok area and Bangkok Metropolitan Region). We hypothesized that weather variables relate to PM2.5 concentrations and could be used to predict the concentrations of PM2.5. The results showed that temperature and precipitation could be used to predict PM2.5 concentrations. We also found that a more accurate model can be obtained by using data of predictor variations over the same period.</p> Chanidapa Winalai Satawat Nanthasen Sudarat Chadsuthi Copyright (c) 2022 Life Sciences and Environment Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2022-09-09 2022-09-09 23 2 409 421 10.14456/lsej.2022.31 STUDENTS' SATISFACTION ON HYBRID LEARNING OF ANIMATION MAJOR UNDERGRADUATE STUDENTS IN CHENGDU, CHINA https://ph01.tci-thaijo.org/index.php/psru/article/view/247844 <p>The study was designed to explore factors influencing the satisfaction of animation undergraduates from Chengdu universities with hybrid learning. First, the conceptual framework in the study was based on three-tier use the model (3-TUM) and the information systems (IS) success model, including Self-efficacy (SE), System quality (SYQ), Information quality (IQ), Service quality (SQ), Perceived value (PV) and Satisfaction (SAT). It also presented relationships between influencing factors in the model. The researcher took an approach of judgement and quota samplings to verify the model by drawing 497 animation undergraduates from three public universities in Chengdu for quantitative research, with questionnaires to collect data. Second, confirmatory factor analysis (CFA) and structural equation model (SEM) were employed for data analysis, including goodness of fit, validity and reliability of structure. The criterion for model fit index was CMIN/DF&lt;3.00, GFI≥0.90, AGFI≥0.80, RMSEA&lt;0.05, CFI≥0.90, NFI≥0.90, TLI≥0.90. Model fit indexes of the adjusted CFA and SEM are within such standards. The above analysis contributed to the extent of influencing relations between various factors: service quality had the biggest positive effect on animation undergraduates’ satisfaction with hybrid learning with standardized path coefficient value of 0.429 (t=9.058***) and had the minimal impact on perceived value as marked by standardized path coefficient being 0.182 (t=3.962***). Perceived value has a direct implication for satisfaction, as evidenced by the standardized path coefficient of 0.275 (t=6.357***). Self-efficacy had a positively strong implication for students’ satisfaction with hybrid learning, which served as the second-leading factor influencing satisfaction with a standardized path coefficient of 0.379 (t=9.398***). Meanwhile, students’ satisfaction with hybrid learning was influenced by information quality and system quality, with the standardized path coefficient of 0.316 (t=8.128***) and 0.264 (t=6.053***) respectively. The study revealed that we need to take into account factors influencing students’ satisfaction with hybrid learning in ways that make their learning more enjoyable. Learning atmosphere for hybrid learning must be refined for better effect and satisfaction.</p> Limei Niu Athipat Cleesuntorn Copyright (c) 2022 Life Sciences and Environment Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2022-09-09 2022-09-09 23 2 422 436 10.14456/lsej.2022.32 CHINESE-ENGLISH MOBILE APPLICATIONS FOR COMMUNICATION OF HEAL MASSAGE PERSONNEL TO ENHANCE EMPLOYMENT OPPORTUNITIES: CASE STUDY OF CHA-AM AND HUA-HIN AREAS https://ph01.tci-thaijo.org/index.php/psru/article/view/247968 <p>The purposes of this research were 1) to gather a body of knowledge on health massage, 2) to survey the needs for application development in various aspects of health massage personnel, 3) to design and develop mobile applications and 4) to evaluate Chinese and English for communication in health massage after using the mobile application.

Two sequential quantitative studies were employed to achieve the aim. Chinese counselors were recruited from several universities in Guangzhou city by using convenience and snowball sampling techniques. Data were collected using the online questionnaire approach. In study 1, a self-assessing counseling performance tool, the Counselor Evaluation Rating Scale (CERS), was translated into Chinese by following a series translation procedure. The reliability and validity were evaluated in two different groups of samples. Specifically, an exploratory factor analysis (EFA) was conducted on 217 Chinese counselors (28.11%men). A confirmatory factor analysis (CFA) was then conducted on another sample of 244 Chinese counselors (27.46% men) to evaluate construct validity. Study 2 investigated the structural relationship and mediation effect among Chinese counsellors (n = 244) using SEM approach. The results are: 1. The 20-item Chinese CERS exhibited excellent internal consistency (α= .90) and adequate three-first-order construct validity among Chinese counselors (χ2/<em>df</em> = 1.63; p &lt; .001; CFI = .90; TLI = .92; RMSEA = .05). 2. The model evaluation and comparison results supported all the hypotheses in the current study. The findings revealed a positive and significant relationship between counselor empathy and counselor performance. Counselor self-efficacy has been implicated in this study as a crucial mediator between counselor empathy and performance.</p> Lijuan Yang Yanbin Jia Copyright (c) 2022 Life Sciences and Environment Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2022-09-09 2022-09-09 23 2 505 520 10.14456/lsej.2022.38 THE RECOMMENDATION OF HEALTHY TOURISM ROUTES FOR ELDERLY IN KHAOKHO DISTRICT, PHETCHABUN PROVINCE BY USING ANALYTIC HIERARCHY PROCESS https://ph01.tci-thaijo.org/index.php/psru/article/view/248748 <p>This research aimed 1) to survey information on routes and deciding factors of health tourism attractions in Khaokho District, Phetchabun Province 2) to develop a health tourism guidance system for the elderly in Khaokho District, Phetchabun Province by using an analytical hierarchical process method and 3) to assess the effectiveness of the system. The samples for collecting data were 10 health tourism specialists and elderly tourists selected by the purposive sampling method for collecting knowledge and assessing AHP application and 50 elderly tourists for assessing satisfaction with the AHP application. The research instruments for collecting data were the questionnaire for surveying the route data and decision factors, the questionnaire for assessing the tourism route selection by the system and the specialists, and the questionnaire for assessing the users’ satisfaction with the system. The statistics for analyzing data used frequency, percentage, mean, standard deviation and content analysis. The results showed 7 destinations for the health tourism route. AHP model for decision making was divided into 3 levels based on the 5ASM concept as 7 criteria. The system development consisted of 3 functions; inserting and calculating the weights, ranking the suitable tour places for the elderly, and showing the tour places information. The system showed that the ranking of tourism routes/ places has accuracy by the specialists for the 3 rankings at 75% and the 5 rankings at 71.43%. The users have satisfaction with the system in overview at a high level. </p> Yupa Kumtapol Thinaphan Nithiyuwith Tassanan Treenuntharath Copyright (c) 2022 Life Sciences and Environment Journal https://creativecommons.org/licenses/by-nc-nd/4.0 2022-09-09 2022-09-09 23 2 521 538 10.14456/lsej.2022.39
