    Disruptive technology has globally transformed education, bringing both opportunities and challenges to educational institutions. Existing research primarily addresses technology integration in education; however, there is a significant gap in understanding how elementary school teachers can develop and exercise digital innovative leadership. This gap is especially pronounced in the Thai context, where traditional teaching methods are rapidly being disrupted by digital innovations. This research aimed to identify and analyze factors influencing elementary school teachers' digital innovative leadership in educational management during the disruptive technology era in Thailand. Utilizing a qualitative methodology, the study employed methodological triangulation. This included document analysis of 20 relevant sources and in-depth interviews with five purposively selected key informants, consisting of senior administrators and experienced teachers. Data analysis utilized directed content analysis and frequency analysis. The findings revealed five crucial factors influencing teachers' digital innovative leadership: Digital Innovative Vision, Digital Skills, Creative and Innovative Thinking, Innovative Teamwork and Participation, and Ethics and Accountability. These interconnected factors provide a comprehensive framework for developing teachers' digital leadership capabilities and offer school administrators strategic guidance for implementing effective professional development programs. The results contribute to both theoretical understanding of digital leadership in education and have practical implications for teacher development in Thailand's evolving educational landscape.

    Effects of Exercise on Physical Performances among Frail Older Adults: A Review Study
    (Graphicsite, 2023-09-26) Sattha Prakobchai; Rungnapa Pongkiatchai; Sresuda Wongwiseskul
    Frailty is a crucial concept in determining physiological reverses among older adults. Physical frailty can predict the vulnerability for community- dwelling older adults as the functional performance declines. Recently, nurses and health care professionals have implemented the strategies to enhance physical capacity among frail older adults. Even the clinical guidelines of physical activity and exercise recommendations are widely published, older adults still engage in a low level of physical exercise. It is notable that exercise intervention is effective way to prevent frailty. This review indicates that a combination of aerobic, resistance exercise, and multicomponent exercise can improve physical performance such as increase muscle strength, balance, muscle mass, gait speed and prevent falls. Frailty is a reversible condition. Therefore, encouraging older adults to perform physical exercise is needed to maintain physical functioning as well as promote quality of life. Nurses play a significant role in frailty recovering both in hospitals and in aged care facilities.

    The research objective was to evaluate the antioxidant activity, the allelopathic potential on germination growth of Neptunia javanica Miq. seeds and the total phenolic content (TPC) of crude extracts and fractions from Lippia nodiflora (L.) Michx. In this research, the ethanol crude extracts of leaves (LE), stems (SE) and roots (RE) from L. nodiflora were subjected to study the antioxidant activity by using DPPH free radical scavenging assay and the allelopathic potential on germination seeds of N. javanica. The RE extract had the highest antioxidant activity with IC50 value of 136.87 ppm. The allelopathic effect of LE extract at a concentration of 20 mg/mL completely inhibited the seed germination of N. javanica. The LE fractions were separated by liquid-liquid partition with hexane and ethyl acetate system to afford the leaf hexane fraction (LH), leaf ethyl acetate fraction (LEtOAc) and leaf hydroethanolic fraction (LW). The antioxidant, TPC and allelopathic activities of all fractions were investigated. The antioxidant activity of LW (158.21) and LEtOAc (175.45) fractions were better than those of LE (296.87) extracts, while LH fraction showed the lowest antioxidant activity at 722.08 ppm. The active allelopathic compounds in LEtOAc at a concentration of 10 mg/mL showed complete inhibition of radicle and hypocotyl on germination seed growth and 50% of seed growth inhibition (IC50) was 3.14 mg/mL. Crude extracts and fractions showed more inhibited radicle growth than hypocotyl growth of N. javanica seeds. The TPC of leaves crude extracts and fractions were the highest. Interestingly, the total phenolic content of LEtOAc fraction, was the highest (0.072 mg GAE/g) that was related to the good allelopathic properties, compared with other fractions and crude extracts. Our results indicate that the ethanolic crude extracts and an ethyl acetate fraction of L. nodiflora leaves can be applied to weed control, especially for N. javanica.

    Germinated black glutinous rice (GBGR) drink in a sachet was developed. The effects of roasting time (0, 5, 10 and 15 min) and brewing time (3, 5, 7, 10 and 15 min) on color, chemical compositions and antioxidant capacity were investigated. Prolonged roasting time increased L*, positive b*, C* and h° values, whereas decreased positive a* value, resulting in lighter color. Ash and carbohydrate contents were higher when longer roasting time was applied; however, aw, moisture and protein contents were lower. GABA contents (61.04 mg/kg) retained in GBGR with 5 min-roasting time. Fat, crude fibers, total phenolic (TPC), total anthocyanin (TAC) contents and DPPH scavenging capacity did not significant change according to roasting time. Regarding brewing time with water at 98°C, L* and h° values of GBGR drink decreased. Higher TPC, TAC and DPPH scavenging capacity of GBGR drink were induced by using short brewing time 3-5 min). Therefore, roasting and brewing time of 5 and 3 min, respectively, were recommended for healthy drink production from GBGR. GABA concentration of 0.17 mg/150 mL was detected in finished product. For consumer acceptability test, GBGR drink was liked moderately and 77% of consumers would like to buy the product. Physical, chemical and microbial changes of the product prototype during storage time of 98 days were accepted following the Thai agricultural standard TAS 4404-2012 Good manufacturing practices for germinated brown rice standard.

    This research aimed to study the effect of chitosan concentration in the chitosan-alginate composite on the texture profile analysis and sensory properties, the correlation between instrumental and sensory properties, and the qualitative change of mulberry juice caviar (MJC) during storage. MJC with chitosan-alginate composite containing chitosan concentrations of 0, 0.5, 1.0 and 1.5% by-weight (ALG 1.5, CHI 0.5, CHI 1.0 and CHI 1.5, respectively) were prepared by spherification process. The results showed that the MJC formed with CHI 1.5 had the best sensory acceptance scores, while which of CHI 0.5 was easier consumed with lower texture profile analysis (TPA) parameters. Meanwhile, the high positive correlation (> 0.7) between the instrumental textures and sensory scores implied that most consumers favoured MJCs with high springiness, gumminess, and chewiness. In addition, chitosan-alginate composite prolonged the shelf-life of MJCs better than alginate alone, especially refrigeration temperature. CHI 1.5 was the most effective against changes in MJC size and total phenolic content, while CHI 1.0 was the best for preserving total anthocyanin content, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and microbiological quality. This product gives a special texture during chewing when adding it into jelly or similar products and it can also use to decorate foods.

    Pomelo (Citrus grandis (L.) Osbeck) is the largest citrus fruit in Thailand, which pomelo juice is commercially produced during the pomelo juice extraction process. After extraction of the juice, the number of by-products that was produced could be a potential source of functional dietary fiber.The objective of this study was to evaluate extraction methods of dietary fiber from pomelo juice byproducts for functional foods and particle size distribution (150, 180, 250 and 425 μm) by pomelo pulp powder (PPP) that was prepared by simply air drying, milling, sieving and grinding. For pomelo pulp dietary fiber powder (PPDFP), the PPP was treated with NaOH and ethanol to remove protein and fat, respectively. After that, analysis of physicochemical and functional properties of PPP and PPDFP found that the PPDFP was richer in total dietary fiber (92.04%), especially insoluble dietary fiber (91.93%). Water holding capacity (WHC) and oil holding capacity (OHC) of PPDFP were higher than those of PPP. Components that can contribute to the bitter flavor of the powders, limonin, naringin and naringenin were considerably reduced in PPDFP, particularly limonin was totally eliminated. Also, the porous structure of PPDFP may facilitate its use in food processing compared to the more sheet-like structure of PPP. The optimum particle size was 150 μm that resulted in powders with increased WHC and OHC. From the above data, it was concluded that the PPDFP was a good source for food dietary fibers that could be used as a functional ingredient in fiber rich food products.

    The objective of this research was to study the effects of nutrient supplement and chitosan on microbial change in an up-flow-anaerobic-sludge-blanket (UASB) reactor during biogas production. Three UASB reactors were operational in this study. All reactors were operated by feeding dilute stillage with chemical oxygen demand (COD) concentration at 10,000 mg/L and 9 days of hydraulic retention time (HRT) under anaerobic conditions. Reactor 2 and reactor 3 were supplemented with nutrient supplement and chitosan, respectively. The results of the environment and pH values of all UASB reactors showed similar conditions with total volatile acid/ alkalinity (TVA/Alk) values of 0.27-0.31. The COD removal efficiency of reactor 1 (stillage), 2 (stillage and nutrient supplement) and 3 (stillage and chitosan) showed about 79%, 84% and 87%, respectively. In addition, it was found that the UASB reactors supplemented with nutrient supplement or chitosan produced higher levels of biogas than those without additives. The 16S rRNA technique by PCR reaction showed that the dominant archaea in the final fermentation of all UASB reactors and in inoculum sample were hydrogenotrophic (genus Methanobacterium) and acetotrophic methanogens (genus Methanosaeta). The methanogens population in the reactor supplemented with chitosan (18.11%) produced more biogas than the ones in the reactor supplemented with nutrient supplement (14.44%) and in the control reactor (15.95%).

The optimal microemulsion formulation was selected by visual assessment according to a transparent and thermodynamically system form. The optimal microemulsion obtained from the experiment composed of 10% w/w glyceryl monostearate (GMS, solid lipid), 10% w/w Tween 80 (surfactant), 15% w/w PEG-40 hydrogenated castor oil (surfactant) and 20% w/w ethanol (co-surfactant). Various processing parameters for the preparation of SLN was carried out using three factors including, 1) warm microemulsion (mL) and iced water ratio (mL), 2) homogenization speed (rpm) and 3) homogenization time (min) and two responses assessed were particle size and polydispersity index (PDI) to obtain a SLNs batch with smaller particle size and optimum PDI. The OMC-loaded SLN had 693.07± 0.05 nm mean particle size and 0.56±0.04 PDI, prepared by optimal processing parameters. The surface morphology of the SLNs was assessed by transmission electron microscopy (TEM), the result found that OMC-loaded SLN showed a smooth surface and spherical shape. Entrapment efficiency of OMC-loaded SLN was found to be 99.89±0.020% . The stability testing of the prepared SLN was studied. Result found that OMC-loaded SLN showed slightly lower stable compared with the initial condition. All obtained results indicated that this method and processing parameters can prepare the SLNs which was suitable for cosmetic application.

    The study aimed to study the effect of the health literacy program on self - management related to food consumption among older adults with hypertension in the community. The study design was quasi-experimental study with pre and posttest groups. The participants consisted of 64 older adults with hypertension who were randomly assigned to an experimental and control group. Participants in experimental group received health education and six sessions of health literacy. Each session lasted 20-60 minutes within eight weeks. Control group received usual care and health education from health provider. self-administration questionnaire (nutrition literacy, food consumption pattern and self-management) was used to collect the data. Data were analyzed using independent t-test. Group reflection was analyzed using content analysis. Results showed that mean score of nutritional literacy, food consumption and self-management of the experiment group was significantly higher than the mean score of the control group (p-value <.001). Results from the reflection in the experimental group suggested some issues, including the understanding, access to information and applying knowledge. Participants suggested the methods to enhance health literacy for self-management on food consumption including providing knowledge, communication, sharing experiences and using photographic media. In sum, health literacy program can be used as a tool to enhance knowledge related to health.

    The objective of this research was to produce a biochar from bamboo handicraft waste via pyrolysis process using a modified 200 L steel drum kiln. The temperature outside the kiln-producing biochar appeared around 500-600°C, closely related to the temperature of slow pyrolysis. The physical and chemical properties of bamboo biochar (BB) were characterized by using proximate and ultimate analysis, Brunauer-Emmett-Teller surface area techniques, elemental analysis, scanning electron microscopy coupled with an energy dispersive spectroscopy, Fourier transform infrared spectroscopy, Raman spectroscopy and X-ray diffraction techniques. It was found that 28.76 ± 2.22% of BB yield with 77.07 ± 1.92 % fixed carbon. As the morphology properties, its surface area and total pore were 247.5 ± 7.1 m2 g-1 and 0.16 ± 0.02 cm3 g-1, respectively. Batch test for removal of natural organic matter (NOM) in Nakhon Nayok River, by adsorbed on BB was studied. The results showed that the percentage reduction of dissolve organic matter (DOC) and absorbance at 254 nm at equilibrium were 71.33 ± 1.46 and 76.51 ± 2.01, respectively, while the adsorption capacity was 4.75 mg.g-1 DOC. Pseudo-second order kinetic model was best suited for describing the adsorption of DOC onto BB. This suggests that interaction of NOM on BB were explored in terms of multicomponent adsorption, which the heterogeneous distribution of the adsorptive sites at biochar surfaces. It was found that biochar is suitable for the adsorption of NOM from surface water and is a low-cost effective adsorbent in the treatment of wastewater. Biochar can be applied for a variety of purposes for example: as biofuels, adsorbents and as soil amendments. In addition, the biochar kiln is small and easy to create, creates no smoke, inexpensive, easy to use, does not take much time to produce and has an eco-friendly processing.
