Parental and peer influence on adolescent smoking in Vietnam
Authors:   , Yen Duong 
Published: September 2023

To estimate the magnitude of the association between parent and peer influences on adolescent smoking as non-; light-; and heavy current smokers. By using data from 18,912 adolescents, ages from 13 to 15 years, from two years 2007 and 2014 of the Global Youth Tobacco Survey in Vietnam, were selected for these analyses. Data collected included measures for the smoking status of the adolescent and their parents and friends. Descriptive analysis was used to describe the characteristics of each individual variable. After that, the ordered logistic regression was applied to estimate the relationship between smoking behaviour of parents and peer, with the level of addiction of current smoking among school-going students. I also added up other variables in the regression model as control variables to further examine the association between the dependent and independent variables. Then, examine this association by some subsample to observe the gender and age trends of these relationships. This analysis confirmed that young people were more likely to use cigarettes when their parents and friends smoked, the status of current smoking here was at a light- and heavy- level as well. Especially, the probability of smoking from the effect of friends’ cigarette use was generally higher compared to the effect of smoking of parents. In addition, there were differences in influence from the smoking of parent and peer by groups of age and gender of adolescents. The influence of parent and peer were increased when students became older from 13 to 15 years old. While gender-specific influences were identified in the peer impacts on adolescent smoking for both boy and girl; parental smoking only significantly associated with boy.
Determinants of healthcare utilization and out-of-pocket expenditure in Thailand
Authors:   , Saichol Piraya 
Published: September 2023

Thailand launched the Universal Coverage Scheme (UCS) in 2001 and most studies are focusing on the impact of the UCS on healthcare utilization and out-of-pocket (OOP) expenditure. None of the studies, however, examines healthcare utilization and OOP expenditure across the three main public health insurance schemes, i.e. UCS, Social Security Scheme (SSS), and Civil Servant Medical Benefit Scheme (CSMBS). Therefore, this study aims to examine the impact of health insurance status and use of health insurance on outpatient service utilization and healthcare OOP expenditure by using the 2017 Health and Welfare Survey data. Given large income and other disparities across Thailand’s regions, regional differences are also explored. The study employed a multinomial logit model for the analysis of healthcare utilization and a two–part model for the analysis of healthcare OOP expenditure. The results reveal that the SSS beneficiaries are more likely to seek care at healthcare facilities than the UCS beneficiaries, but this is only observed in the Bangkok and central region. The use of public health insurance is found to decrease the amount of OOP expenditure, conditional on incurring OOP, in case of total healthcare cost and direct medical cost, while it increases the amount of OOP expenditure in case of transportation cost. Individuals who use the UCS incur the lowest amount of OOP spending in terms of total healthcare cost, direct medical cost and transportation cost. In addition, people who live outside of Bangkok incur lower OOP for total healthcare cost and transportation cost than those living in Bangkok. Overall, the results suggest that the UCS is very successful in creating financial protection for the majority of Thai citizens. The area of residence is found to have an impact on both healthcare utilization, as well as probability of incurring OOP and amount of OOP expenditure. These findings raise some concerns about the inequality across the three public health insurance schemes and the regional disparities in Thailand, which should be solved in order to increase equality in healthcare utilization across the Thai population.

Published: September 2023

This study examined the relationship between social participation and smoking among middle-aged and elderly persons. This study used a secondary dataset drawn from the China Health and Retirement Longitudinal Study (CHARLS,2015). In this nationally survey, the number of observations was 9,876. The dependent variable used in this study is smoking and non-smoking. Smoking includes light smoking, moderate, and heavy smoking. The explanatory variables are family factors, demographic characteristics, and socioeconomic factors. Factors associated with smoking were examined with logistic regression model.

The results showed that gender, marital status, health self-assessment, pension, chronic disease, playing Mahjong, playing chess, playing cards, or going to the community club, going to a sport, social, or other kinds of the club, using the Internet are the influencing factors of middle-aged and elderly smoking. Middle-aged and elderly who played Mahjong, played chess, played cards, or went to community club are risk factors for smoking (p<0.001). Middle-aged and elderly people who played Mahjong, played chess, played cards, or went to community club are 1.34 times more likely to smoke than non-smokers. (OR=1.342316). Middle-aged and elderly people who went to a sport, social or other kinds of clubs are protective factors for smoking(p=0.022). Middle-aged and elderly people who went to a sport, social or other kinds of clubs are 0.79 times more likely to smoke than non-smokers (OR=0.7941856). Middle-aged and elderly who used the Internet are risk factors for smoking(p=0.024). Middle-aged and elderly people who used the Internet are 1.31 times more likely to smoke than non-smokers. (OR=1.314805). The impact of other social participation on smoking among middle-aged and elderly people are not statistically significant at 5% significance level. The results altogether indicated a clear relationship between social participation and smoking.

It is necessary to distinguish which social participation is beneficial to middle-aged and older people's physical and mental health, in which social participation is a risk factor for a healthy lifestyle for middle-aged and elderly people. The community should promote a healthy lifestyle for middle-aged and older people. Post signs of smoking hazards in the community, for example. Increase investment in community cultural facilities to provide more suitable places for middle-aged and older people. Health departments and government departments should actively cooperate in the tobacco control plan and implementation.

The situation directly affects Thai tourism industry which is one of the significant industries in Thailand that generates large amount of income each year. This is because Thailand is very popular among international tourists, especially Korean tourists, Korea is ranked one of the top five countries base on the number of tourists entering Thailand with more than a year annd Korean tourists spend more than 80,000 million baht each year. There is a variety of services in Thailand for Korean tourists, so during the spread of COVID-19, many businesses in tourism industry faces with severe impact. Thus, this research aims to study the effects of COVID-19 towards Thai tourism businesses which aim at Korean tourists. The research uses an in-depth interview on the related business groups in order to find the effects on and problems faced by, their businesses, and the strategies they use during the crisis. Additionally, the research aims to find the solutions to restore Thai tourism industry after the crisis. The result illustrates that there are different effects toward each type of business, but most of them face with an insufficient income to run the business due to the disease prevention and control measures. Each business has different strategies to cope with the problems, most businesses decide to decrease their cost, such as employees' salary, while trying to increase their income. The tourism industry needs help and support from both government and private sectors on finance and policies which will help them to compete with other countries by increasing public relations and stability in order to accelerate confidence and encourage tourists to return quickly.

Published: September 2023

Three-dimensional printing has been a widespread solution of fabricating geometrical customized products. Any 3D printed product is normally fabricated at a position defined with respect to the coordinate system of the corresponding 3D printer. So, the 3D printing cannot be conveniently implemented in some fabricating applications in which fabricating positions are commonly constrained to some physical references, e.g., architecture construction, surface restoration, food decoration, etc. This research aimed to integrate the 3D printing with machine vision, which is vastly used for guiding robotic systems to operate at desirable positions constrained to physical objects. Hence, the 3D printing can be conveniently and affordably implemented at any position constrained to any physical reference. The proposed machine vision integrated 3D printing system comprises a 3D printer, which is originally constructed in this research, a commercial web camera, and a commercial computer. The web camera was equipped to the printhead of the 3D printer, and necessary computer programs were developed. Then, evaluating products were fabricated on evaluating physical reference, in order to evaluate the machine vision integrated 3D printing system. From the successfully fabricated results of the evaluating products, the machine vision integrated 3D printing system gives promise of conveniently, affordably, and accurately, implementing the 3D printing in the mentioned applications.
Effects of rhinacanthin-C in multidrug-resistance breast cancer cells
Authors:   , Chaisit Suwichak 
Published: September 2023

Rhinacanthin-C (RN-C) is a major bioactive naphthoquinone ester found in Rhinacanthus nasutus Kurz (Acanthaceae). This compound has potential therapeutic value as an anticancer agent. Rhinacanthin-C was reported to enhance doxorubicin cytotoxicity in breast cancer cells through direct inhibition of P-gp activity. However, its ability in reversing multidrug resistance (MDR) in cancer cells through the down-regulation of P-gp expression, alteration of detoxification system, and increase in apoptosis proteins remains unreported. Thus, this study was to investigate the potential MDR reversal effect of rhinacanthin-C and its underlying mechanisms in MCF-7/DOX. In this study, rhinacanthin-C (1 µM, 48 h) significantly enhanced cytotoxicity of camptothecin, doxorubicin, and etoposide. Apparently, the loss of P-gp function in the rhinacanthin-C-treated for 24- h in MCF-7/DOX cells was associated with the reduction of MDR1 mRNA expression and P-gp protein levels. In addition, the down-regulation effect of rhinacanthin-C on P-gp expression involved with suppressions of the Akt/NF-kB signaling pathway and YB-1 expression, but not the MAPK/ERK1/2 signaling pathway. The result also demonstrated that rhinacanthin-C (up to 3 µM, 24-h) was able to produce intracellular ROS and potentiate H2O2 toxicity, leading to increased apoptosis in MCF-7/DOX cells. Moreover, this compound inhibited the MAPKs signaling, resulting in changes in the Bax/Bcl-2 ratios and a decrease in the expression of PARP protein. In addition, rhinacanthin-C might increase cellular stress and promote apoptosis via inhibition of the Akt/GSK-3β/Nrf2 pathway, leading to the down-regulation of antioxidant and detoxifying enzymes such as NQO1 and HO-1. Taken together, rhinacanthin-C displayed its MDR reversal effect in MCF-7/DOX cells through down-regulation of MDR1 and P-gp expression by inhibiting Akt/NF-kB signaling pathway and YB-1 expression. In addition, rhincanthin-C was able to induce apoptosis through ROS production and suppression of the cell survival systems mediated by the MAPKs and Akt/GSK-3β/Nrf2 signaling pathways.
Responsiveness of the Thai version of the Patient Reported Outcomes Measurement Information System-29 (PROMIS-29) in patients with chronic low back pain
Authors:   , Khutok Kornkanok 
Published: September 2023

Background: The Patient-Reported Outcomes Measurement Information System-29 (PROMIS-29) questionnaire assesses 7 health related quality of life domains. However, research to evaluate the responsiveness and minimal clinically important differences (MCIDs) of the PROMIS-29 scores in patients with chronic low back pain (cLBP) is limited. Purpose: To evaluate responsiveness and estimate the MCIDs for PROMIS-29 scales in patients with cLBP. Method: One hundred and eighty-three participants with cLBP took part in the study. They completed the PROMIS-29 scales at baseline, 4 weeks, and 8 weeks of the study. Responsiveness of the PROMIS-29 scale scores was evaluated by examining the mean change scores, effect sizes (ESs), standardized response means (SRMs) based on the global perceived effect (GPE) over time, including correlations with GPE. MCIDs were estimated by computing optimal cut point on the receiver operating characteristic curve and standard error of measurement (SEM) statistics for each scale. Results: The mean change scores, ESs, and SRMs increased as a function of the GPE ratings. At 4-week follow-up, the ESs and SRMs showed large magnitudes (ESs and SRMs ≥ 0.80) for Pain Intensity, Physical Function, and Anxiety scales in very much improved group. The correlations between change scores and GPE ratings were mostly weak in magnitude at 4 and 8 weeks. The MCID estimates computed as Pain Intensity 1.50 points; Physical function 3.60 points; Anxiety 5.88 points; Depression 5.25 points; Fatigue 7.75 points; Sleep Interference 3.90 points; Ability to Participate in Social Roles and Activities 4.58 points; and Pain Interference 4.85 points. Conclusion: The PROMIS-29 scale scores assessing pain intensity, physical function, and anxiety evidenced the most responsivity in the study sample.
Effects of polyaniline thickness on photovoltaic properties of PANI/tio2 photovoltaic cells
Authors:   , Auisakul Akkharaphak 
Published: September 2023

Polyaniline (PANI) is a cheap conducting polymer that exhibits p-type properties with high conductivity and unique redox properties. In this work, PANI was synthesized directly on TiO2/FTO substrates by electropolymerisation from acidic aqueous solutions of aniline to form PANI/TiO2 p-n junctions with photovoltaic properties. The thickness of the PANI layer was varied by varying electrodeposition time: 15, 30, and 45 min at the same current density of 2 mA cm-2. The thicknesses of the deposited PANI layers were examined with Scanning Electron Microscope (SEM). Short-circuit currents (ISC) and open-circuit voltages (VOC) of fabricated Pt/PANI/TiO2/FTO cells are investigated. It was found that the PANI electrodeposition time at least 30 min corresponding to a PANI thickness of 399 nm was required for the cell to exhibit significant photovoltaic properties. Furthermore, the TiO2 nanorods that is a remarkable morphology of the n-type TiO2 was synthesized by electrochemical anodization of titanium in a fluoride-based electrolyte with varying anodization times: 45 and 60 min at the constant potential of 60 V. It was found that the anodization time at 60 min is the sufficient condition for the PANI electrodeposition at 45 min to exhibit photovoltaic properties.
