The study objectives are to verify a path analysis of mental health among Thai elderly with diabetes mellitus. The sampling method used is stratified random sampling. The sample size comprises 2,000 Thai elderly persons over 60 years old with diabetes mellitus. The variables are divided into individual (food, exercise, BMI and drugs), psychological (illness perception) and social factors (family support). Data are analysed using path analysis. The total variables described mental health change by 64.5%. It was found that exercise, illness perception, food and drugs as variables had a direct influence on mental health with standardised regression weights of 0.732, 0.347, 0.243 and 0.050, respectively (p-value<0.01). The exercise variable had a direct effect on mental health the most. The benefits of this study include providing recommendations to guide future mental health policy and to reduce the cost of health maintenance in Thailand. © 2016 Universiti Putra Malaysia Press.

Impure BiFeO3 as a visible light photocatalyst for phenol degradation was synthezied via solid state method. The calcined temperatures of catalysts were studied. The characteristics of the catalysts were determined by XRD, SEM/EDS and BET. The catalysts were mainly composed of rhombohedral distorted perovskite-type BiFeO3 phase with impurity phases (B2Fe4O9, Bi25FeO40 and Bi2O3). Photocatalytic activity of phenol (5 mg/l) was studied in the impure BiFeO3 illuminated with 200 w fluorescence lamps. The catalyst amount and initial pH value of phenol solution on the photocatalytic effiency have been also investigated. In the present experiments, the catalyst calcined at 800°C shows the highest activity. The optimum loading of impure BiFeO3 and pH value were obtained to be 0.5 g/l and 6, respectively. © (2015).

The aims of this research were to study both direct and indirect path analyses of mental health, and to analyse a causal relationship of each variable. A cross-sectional study used stratified random sampling to select Thai immigrant employees in Pranakron Si Ayutthaya Province, Thailand. General data were analysed by number and percentage. The mental health variable was measured by THMHI-15. The latter was analysed by general statistic, and a path analysis. The results found that job conditions and distance travelled between house and workplace had a direct effect on mental health with a standardised regression weight of 0.581, and −0.443, respectively (p value <0.01). It was found that housing conditions had no effect on mental health. The income variable had a direct influence on mental health with a standardised regression weight of 0.68 (p value <0.01). This research indicated that job conditions were an important factor related to mental health. © 2015, Springer Science+Business Media New York.

This work evaluated the effect of high hydrostatic pressure (300-500 MPa/25°C/5-20 min), ultra-sonic (20-60% amplitude/20 kHz/5-20 min) and thermal (50-100°C/1-5 min) processing on phenolic contents and antioxidant capacities of honey from the longan flower. Total phenolic compounds, total flavonoids and antioxidant capacity (DPPH and FRAP assays) were determined. It was found that high pressure, ultra-sonic and thermal treatments had a significant effect on antioxidative properties of honey sample. After pressurization, the quantities of total phenols, flavonoids and antioxidant capacity in honey signi ficantly increased with the increasing pressure levels and processing times, in particular samples pressurized at 500 MPa for 20 min. Similarly, these bioactive compounds in honey samples processed by ultra-sonication were also enhanced when the amplitude levels and treatment times increased. For thermal treatments at 50 and 70°C, all antioxidative constituents had no significant differences when compared to the control, while the sample heated at 100°C contained the lowest levels of phenols and antioxidant capacity. Therefore, both high pressure and ultra-sonic processing are an alternative technique to preserve the antioxidative qualities of longan flower-honey, while also not affecting the nutritional values. © 2015 Elsevier Ltd.

This research aimed to study a history of community bazaars along the Thachin River; to analyze factors affecting the collapse of the bazaars; to examine factors that helped sustain their existence; and to propose a model for restoring them. Data were collected from interviews, observations and questionnaires. Content analysis and descriptive statistics were used to analyze the data. The research findings were as follows: 1) In Suphanburi Province, there were 16 community bazaars along the Thachin River. All of them had been prosperous in the time when the river was used as a main transportation route. At that time the bazaars served as a trading center and a ferry port. The goods were mainly agricultural products, such as rice, dried tamarind, charcoal, dried chilly, coconuts, and sugar, including consuming products such as soap, toothpaste, detergent and fabric carried by boat from Tha Tian Pier in Bangkok. 2) The external factors affecting the collapse of the community bazaars along the Thachin River were the development of road transportation which was faster and more convenient; the construction of the bridges across the Thachin River which made travelling across the river much more easier; the rapid growth of temporary markets; the expansion of foreign superstores and convenient stores; and the neglect of community leaders and local administrators to protect these traditional bazaars. The internal factors were the lack of unity and the migration of the community members. 3. The external factors that helped sustain the existence of some community bazaars along the Thachin River was the collaboration from outside networks while the internal factors were the cooperation among people in the communities; the strengths of individual bazaars in terms of location and distinctive food; and their expostulation against disadvantageous policies of the local administrators. 4. A model for restoring community bazaars along the Thachin River in Suphanburi Province was aimed to stimulate the lively atmosphere of the bazaars, to promote the cooperation and the sustainable incomes of the community members. The designed model consisted of 4 steps: 1) analyzing self potentiality and shared vision, 2) analyzing customers' needs, 3) creating a network for knowledge exchange both inside and outside the community, and 4) designing an action plan with clear implementation and periodically conducting an assessment for improvement. © EuroJournals Publishing, Inc. 2012.
