Revisiting the Period Change and Frequency Analysis of a Variable Star SZ Lyncis

2024-10-25T14:18:20+07:00

This study aims to investigate the period change of the variable star SZ Lyncis. The observations were conducted at the Regional Observatory for the Public, Nakhon Ratchasima (ROP-NMA), operated by the National Astronomical Research Institute of Thailand (NARIT), on January 8^th-9^th and February 19^th-20^th 2024. The data was acquired using the CCD camera with a B-filter mount on the 0.7-m reflecting telescope. We report the period change of 1.37(±0.08)´10^-12 day cycle^-1. Analysis of the O-C diagram revealed the presence of a binary companion with a semi-amplitude of 0.0052(±0.0002) days, the projected semi-major axis of 0.90(±0.04) AU, the eccentricity of 0.25(±0.09), and the orbital period of 1184.1(±1.5) days and the mass function of 0.07(±0.01) M_⨀. We also identified the time-series light curve data using the Discrete Fourier transform (DFT) in the Period04 package and obtained results of four frequencies. The main frequency of 8.29630(±0.00002) cycle day^-1 corresponds to a period of 0.1205357(±0.0000003) days. These results contribute to our understanding of the pulsation properties of SZ Lyncis and its binary system.

The Formaldehyde, TVOCs, PM2.5 and PM10 Concentrations at Outdoor Street Food in Kalasin, Thailand

2024-10-25T14:18:18+07:00

Human health and well-being are directly impacted by air quality. Cardiovascular and respiratory problems have been linked to exposure to pollutants such as formaldehyde, total volatile organic compounds (TVOCs), and particulate matter 2.5 and 10 micrometers (PM2.5 and PM10). This study aimed to quantify formaldehyde, TVOCs, PM2.5, and PM10 levels in the outdoor air at street food vendors in Kalasin, Thailand. The study was conducted at street food vendors in the province of Kalasin. Formaldehyde values at the top five food stalls in Kalasin ranged from 0.58 to 1.41 mg/m³. The PM2.5 values ranged from 2.29 to 9.43 ug/m3, and the TVOC values ranged from 2.91 to 7.02 ug/m3, with PM10 concentrations ranging from 2.86 to 7.29 ug/m3. Drawing on data about these pollutant concentrations across five distinct locations, the following recommendations can be put forth: Elevated levels of formaldehyde, TVOCs, PM2.5, and PM10 in certain areas can have detrimental effects on the environment and human well-being.

Processed Seafood Sustainability Supply Chain Management Practices: A Comparison of Community Enterprises and SMEs

2024-12-09T13:57:26+07:00

The purpose of this study was to empirically examine current manufacturing practices of sustainable supply chain management (SSCM) in processed seafood supply chain management, looking at the size difference between specific manufacturing organizations: community enterprises and SMEs. A survey was undertaken to collect data from processed seafood producers in the Rayong and Chonburi provinces, which are the main areas of processed seafood production in Thailand. The final 32 valid responses provided a response rate of 54.24%. The Wilcoxon Rank-Sum Test, a nonparametric test statistic, was utilized to compare the mean difference between the Rayong and Chonburi groups of processed seafood producers. The results indicated that SMEs have a significantly higher potential than community enterprises in terms of plan, source, make and delivery. Semi-structured interviews highlighted issues regarding SSCM practices, such as a lack of knowledge of how to achieve sustainable benefits, a lack of technology use, and the instability of raw material supply from the sea, related to weather conditions, leading to difficulties in production planning and sourcing. The results of this study can be used to reflect the current status of SSCM practices. Therefore, the findings should assist both community enterprises and SMES implement more efficient processes, leading to higher performance.

The Prevention of Acute Diarrhea in the Elderly in Chachoengsao Province, Thailand

2024-12-19T13:59:26+07:00

Acute diarrhea is a preventable and controllable disease, but it is the number one cause of illness among all surveillance infectious diseases in Thailand, especially among the elderly. Acute diarrhea is the number one disease requiring epidemiological surveillance in Chachoengsao Province. The occurrence of acute diarrhea in the elderly causes complications and has a higher chance of death than in other patients. This research aimed to study the factors related to preventing acute diarrhea in the elderly in Chachoengsao Province. This study was a cross-sectional study. The study examined elderly people's knowledge, attitudes, perceptions, and behaviors related to acute diarrhea. The sample comprised 390 elderly individuals from Mueang District, Chachoengsao Province, selected through stratified random sampling. Data were collected using a questionnaire to assess knowledge, attitudes, perceptions of risk and severity, self-efficacy, and preventive behaviors regarding acute diarrhea. Data were analyzed using descriptive statistics and Pearson’s Product Moment Correlation Coefficient. The results revealed a moderate relationship between self-efficacy, knowledge, perceived severity, attitudes, and the prevention of acute diarrhea in older adults (r=0.662, 0.645, 0.588, 0.543, p<0.01). The perception of risk was a very low negative related to the prevention of acute diarrhea in the elderly (r=0.269, p<0.01). The study found a positive association between the factors of interest and the prevention of acute diarrhea in the elderly, although some variables exhibited a negative relationship. Therefore, it is necessary to encourage the elderly and their family to be aware of the risk of acute diarrhea. Local government organizations, the Subdistrict Health Promoting Hospital, community organizations, and community leaders should participate in setting disease surveillance measures such as washing hands often, eating clean, cooked food, drinking clean water, and disposing of garbage properly, to prevent the spread of the disease.
