Natha Methabutsayathon, Dussanee Bunpitaksakun — Thu, 07 Aug 2025 00:00:00 +0700

The objectives of this research study were to 1) the level of diabetes prevention among people 2) the correlation between personal factors, social support and health belief with diabetes prevention among people and 3) the factor affecting to diabetes prevention among people. The sample group consisted of 381 people in Bang Len District, Nakhon Pathom Province. Selected by simple random sampling. Data were collected by questionnaires and analyzed by descriptive statistics, Chi-square, Pearson's correlation coefficient, and stepwise multiple regression. The objectives test results showed that 1) the diabetes prevention among people was at the moderate level (x ̅ = 74.76) 2) the social support factor and health belief factor were correlated with diabetes prevention among people and 3) the social support factor and health belief factor can explain variations in diabetes prevention among people 32%. (Adjusted R2 = 0.32, p-value <0.05). Additionally, the development approach is that relevant agencies can use the research results to plan to promote social support and create health beliefs so that people can continue to prevent diabetes, which will result in a decrease in the rate of diabetes and increase the health people.

The Relationship between Working Capital and Debt Service Coverage on Return on Assets of Companies Listed on the Stock Exchange of Thailand: Reflecting the SET50 Index

Tuanta Intakunjenda, Jackraphan Phongpetra — Thu, 07 Aug 2025 00:00:00 +0700

This research aims to 1) study the relationship between working capital and returns asset 2) study the relationship between debt repayment capability and returns on asset of companies listed on the Stock Exchange of Thailand: reflecting the movement of the top 50 stock index. The sample group consists of 30 companies from 2019 to 2023. This is quantitative research that collects secondary data. The statistics used in data analysis include descriptive statistics, Pearson's product momentum analysis, and multiple regression analysis. The results of the research found that working capital has a statistically significant negative relationship with asset returns, reflecting that holding a high level of working capital may negatively affect operational efficiency. In terms of debt repayment capability, the results of the research show that average debt collection period has a statistically significant negative relationship with asset returns, while average payment period has a positive relationship. When considering the level of influence, average debt collection period has the most influence on asset returns, followed by working capital and average payment period, respectively. The results of this research indicate that organizations should focus on managing trade receivables and maintaining an appropriate level of working capital to increase operational efficiency and asset returns.

Effects of Methanol Addition on the Structural, Optical, and Electrical Properties of PEDOT:PSS Films

Thu, 07 Aug 2025 00:00:00 +0700

PEDOT:PSS is a highly potential transparent conductive material for applications in electronic devices and solar cells. This study aims to investigate the effects of methanol on the structural, optical, and electrical properties of PEDOT:PSS films by adding methanol at ratios of 1:1, 1:2, 1:4, and 1:8. The PEDOT:PSS films with methanol addition were coated onto fluorine-doped tin oxide (FTO) conductive glass, and their characteristics were examined using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible (UV-Vis) spectroscopy, and a four-point probe method to analyze crystal structure, functional groups, optical transmittance, and sheet resistance, respectively. The results revealed that the PEDOT:PSS films exhibited no distinct crystallographic peaks, indicating that the structure remained amorphous. The functional group analysis confirmed the presence of key vibrational signals corresponding to C-H, C=O, C-C, C-S, and SO42-, which are characteristic of PEDOT and PSS. Meanwhile, the average optical transmittance in the visible light range remained approximately 75% across all methanol ratios, suggesting that methanol incorporation did not significantly alter the structural and optical properties. However, the total sheet resistance was significantly reduced, with a minimum value of 6.69±0.04 /sq at a PEDOT:PSS-to-methanol ratio of 1:4. Therefore, optimizing the methanol ratio is a crucial factor in enhancing the electrical properties of PEDOT:PSS films.

Internal Communication, Organizational Trust, and Work Effectiveness of Employees in a Telecommunications Service Company

Thu, 07 Aug 2025 00:00:00 +0700

This research aimed to 1) study the factors of internal communication, organizational trust, and work effectiveness, 2) compare the organizational trust categorized by personal factors, 3) investigate the internal communication affecting organizational trust, and 4) investigate the organizational trust affecting work effectiveness. The population used in this research was 93 employees in a telecommunications service company. The research instrument was a questionnaire. Statistics for data analysis were gathered according to frequency, percentage, mean, standard deviation, F - test and stepwise multiple regression analysis. The research findings were as follows: 1) The overall internal communication, organizational trust, and work effectiveness were at a high level. 2) the employees with different of personal factors showed no significant differences on organizational trust. 3) Clarity, source, and continuity significantly affected the organizational trust at the .01 level. 4) Organizational trust significantly affected the work effectiveness at the .01 level.

Factors affecting brand loyalty of furniture customers In Bangkok metropolitan area

Anon Samranphan, Pongsan Tanyong — Thu, 07 Aug 2025 00:00:00 +0700

This research aimed to study: 1) the level of service quality, brand equity, trust, and brand loyalty of furniture customers in Bangkok Metropolitan area; and 2) the factors affecting brand loyalty of furniture customers in Bangkok Metropolitan area. This research applied quantitative methodology. The samples were selected by convenience sampling. The research sample consisted of 205 furniture customers. The research instrument was a questionnaire constructed by the researcher. Statistics used for data analysis included frequency, percentage, mean, standard deviation, and multiple regression analysis. The research results were as follows: 1) All levels of service quality, brand equity, trust, and brand loyalty were at a high level. 2) The factors affecting the brand loyalty of furniture customers in Bangkok Metropolitan area were service quality (X1), brand equity (X2), and trust (X3). These factors together predicted brand loyalty of furniture customers in Bangkok Metropolitan area at a percentage of 63.60. The raw scores equation was presented as follows:
Y ̂_tot = -.137 + .238**(X1) + .263**(X2) + .537**(X3)

Phytochemical content and antioxidant activity of Butterfly Pea extract using different extraction methods

Kittipot Permpul , Phimonphan Teamkratok, Pimchanok Satapoomin, Intira Koodkaew — Thu, 07 Aug 2025 00:00:00 +0700

Butterfly pea (Clitoria ternatea) is a plant known for its diverse bioactive properties. This study aimed to investigate the phytochemical contents—phenolic compounds, flavonoids, vitamin C, and anthocyanins—as well as the antioxidant activities of butterfly pea flower extracts obtained through maceration and Soxhlet extraction methods. The results revealed that the phytochemical content and antioxidant activity of the extracts increased with concentration. Phenolic compounds were found in the highest amounts (up to 156.12±17.98 mg GAE/g extract), followed by flavonoids, vitamin C, and anthocyanins, respectively. Comparatively, Soxhlet extraction yielded higher levels of phenolic compounds, flavonoids, and vitamin C, whereas maceration resulted in greater anthocyanin content and reducing power. However, there was no statistically significant difference in DPPH radical scavenging activity between the two extraction methods, with EC₅₀ values of 1.49 and 1.57 mg/mL for maceration and Soxhlet extraction, respectively. These findings indicate that butterfly pea flowers are a rich source of phytochemicals and antioxidants, and that the extraction method influences the yield of bioactive compounds.
