Vatcharaporn Chunsandee — 2026-06-17

In 2022, Tak Province has the 5^th highest number of dengue fever patients in Thailand. Quantitative methods are an important tool in planning surveillance for determining appropriate measures. This study forecasts the number of monthly dengue fever cases in 2023 in Tak Province using the SARIMA or ARIMA(p, d, q)(P, D, Q)₁₂ model compared with the Gray System Theory model to forecast total dengue fever cases in 2023 and then distribute the number of monthly cases with a seasonal index according to the pattern of the data shown. The results showed that the number of annual and monthly patients tends to decrease. The seasonality index shows the number of monthly cases spikes in May and peaks in July then decreased until March and April. Therefore, the annual forecasting method was used with the Gray system model. The GM(1,1) EPC model has an average percentage of The lowest absolute error (MAPE) is 2.51, so it is distributed with the seasonal index, which is called the Gray hybrid forecast. The ARIMA(2, 1, 2)(0, 1, 0)₁₂ model has a MAPE value of 13.25. When validating with the number of patients January to October 2023, according to the Disease Surveillance Reporting System 506, it was found that the Gray hybrid forecast and ARIMA(2, 1, 2)(0, 1, 0)₁₂ had MAPE values of 66.11 percent and 124.05, respectively, which were not very good at forecasting. However, quantitative predictions of seasonal indices have been shown to indicate periods of disease severity.

This research aimed to investigate the use of cold shock treatment (CST) combine with 0 50 and 100% of aloe vera gel coating which effect on postharvest quality of lime compares with non–cold shock treatment (NCST). All samples were packed in foam trays covered with polyvinyl chloride (PVC) film and storage at 12.5 degree Celsius, 78 percent relative humidity. A factorial in completely randomized design for this experiment. The result shown that both concentrations of coated lime with aloe vera gel had less fresh weight loss than uncoated lime during the storage life at 12-24 days with the highest mean 2.36% 2.34% and 3.13% respectively, and were able to decrease the yellowing of the skin. The hue angle of coated lime was significantly higher than that of uncoated lime (p≤0.05). On the last day of the experiment, with values of 111.97, 111.98 and 107.66, respectively. The change in chlorophyll and carotenoids content, total soluble solids, titratable acidity and firmness was no significant difference (p>0.05). However, the lime coating with both concentrations of Aloe vera gel was able to extend the storage in the range of 21.5-22.0 days which is about 1 week longer than the uncoated produce. In case to the cold shock treatment, it was found that there was no significant effect on the delay in quality change and shelf life of lime (p>0.05).

This single group quasi-experimental research study measuring before and after the experiment aimed to understand reasons and factors of not coming to receive cervical cancer screening services among women, to develop an incentive model of changing cervical cancer screening behaviors and to evaluate the incentive model. The concept of Information-Motivation-Behavior skill: IMB Model was applied for creating motivational activities. Research samples were 395 women aged 30-60 years in the responsible areas of Nonthaburi Municipality Public Health Service Center 2, Suan Yai. Simple random sampling method was utilized. Research instruments were as follows: 1) Questionnaire 2) Motivational activities to change cervical cancer screening behavior with a 4-week period, 3) Pre-posttest knowledge assessment and 4) satisfaction of the activities. Data were analyzed by percentages, means, standard deviations, and paired t-test. The findings illustrated that most of the participants had never been screened for cervical cancer (58.23%), with the main reason of having no abnormal symptoms. The overall levels of health perception including the perception of risk opportunities ( =2.33, S.D.=0.49) and perception of obstacles ( =1.78, S.D.=0.68), were at a moderate level. The perception of disease severity ( =2.39, S.D.=0.45) and the perception of benefits ( =2.76, S.D.=0.38) were at a high level. The results of creating motivation using the IMB Model concept found that the participants had a significantly higher average knowledge score of cervical cancer after participating in the activities compared with before participating (t=43.366, p<.001) The results presented that the motivational model supports women to gain knowledge about cervical cancer and help create incentives for increased cervical cancer screening. Public health personnel should apply this model for creating women’s motivation to change cervical cancer screening behavior in the community.

Sensor for Homocysteine Measurement in the Indicate Cardiovascular Disease

Suparerk Oonchit — 2026-06-17

Cardiovascular diseases are top-mortal chronic disease. The indicator of cardiac diseases that can show myocarditis is homocysteine (Hcy) because of its specificity and susceptibility. Currently, the method for quantity analysis of homocysteine uses a high-performance liquid chromatography system that uses fluorescence as a detector or an analysis by immune system using antibodies to homocysteine. These methods acceptable exact homocysteine analysis results but the disadvantage is that it takes time to analyze, the tool is expensive, and cannot be used in the field or at medical service points. Thus, in this research, an artificial bioreceptor has been synthesized for binding homocysteine by the surface modification of the electrode with composite material of multi-wall carbon nanotubes at the amount of 0.25, 0.5, 0.75 and 1 gram together with chitosan at the amount of 0.2 gram in every ratio. The SEM has been confirm the surface modification with nanocomposite and the analysis of electrochemical properties with Cyclic voltammetry (CV). Results revealed that the surface modification with nanocomposite is capable of effective homocysteine detection, stability and fast analysis time. This sensor design will be employed as a new bioreceptor for detect complex protein structures on serum samples.
