    (Research and Development Institute Suan Dusit University, 2019) Sirikorn Rochanasak; Wassana Chakkaew; S. Rochanasak; Faculty of Management Science, Suan Dusit University Lampang Center, Lampang, 52100, Thailand; email: sirikornbiloxi@yahoo.com
    The research was carried out to fulfill the main objectives to help 27 second-year students of second semester of academic year of 2016�s Culinary Technology & Services program to develop core English communicative skills. Regarding the tools used, relevant useful tests were conducted in which the tests processes were comprised of: 1) Pre-test: 20 questions of aptitude test related to job interviews. 2) Post-test: which comprised of resume� writing, oral/Q/A tests given at the end of the semester to test the students� speaking and responding abilities to the questions related to job interviews with an aim to test and to improve their understanding of parts of speech and correct usage of vocabulary, and 3) Questionnaires to measure their satisfaction (5-level Likert scale) which ranges from 1 as least satisfaction to 5 as most satisfaction and was analyzed by using descriptive statistics. Hence, the Pre-test result indicates the average score of 45%. Regarding Post-test, the result shows the average of 64%. In addition, the questionnaires� results relevant to satisfaction towards conducted English training activities to improve the 4-core skills and better understanding of job interviews and resume� writing indicate the score of 4.00 (high satisfaction) with the highest aspect towards resume� writing enhancement at 4.33 (high satisfaction). For the low aspect consistings of, unable to comprehensively read and analyze job classified ads, and unable to fully grasp and understand the whole job interview conversational contexts score at 3.33. To make the process more credible, conversational test (mock-up interviews) was also applied with the moderate score of 68%. In conclusion, the end result of the questionnaires shows a high satisfactory level at 4.05. � 2019, Research and Development Institute Suan Dusit University. All rights reserved.

    Disclosure of information accompanying financial report, especially information that represents the educational institutionsÕ sustainability for stakeholders and users of financial reports to have confidence in the educational institutionÕs learning management and its quality. Therefore, it is imperative that education administrators understand, respond to and meet the expectations and needs of stakeholders by disclosing financial reports information in accordance with sustainability reporting guidelines. Furthermore, the report can be served as an assessment tool when evaluating the institutionÕs performance. Other than financial report, stakeholders and related parties can also access to other needed information. The reportÕs important areas comprise of Environmental Dimension which applies to the impact of the organization have on living and non-living things, including ecosystems, soil, air and water; Social Dimension refers to the impact on social system caused by the organization's operation, and Governance and Economic Dimensions are the impact of the organization has on the overall economic system of stakeholders at the local, national and global levels. © 2022, Research and Development Institute Suan Dusit University.

    Effect of Drying Temperature on Physicochemical Properties, Bioactive Compounds, Antioxidant, and Antibacterial Activities of Three Sweet Potato Cultivars
    (Journal of Food Health and Bioeviromental Science. 17(3). 1-10, 2024-12-12) Phuriwat CheeKham; Utsaphong Uprarawanna; Sirikorn Rochanasak
    This study investigates the impact of drying temperature (60-100°C) on the physicochemical properties, bioactive compounds, antioxidant, and antibacterial activities of three sweet potato cultivars: yellow (HRDI Sp-74), orange (HRDI Sp-72), and purple (HRDI Sp-61). Using a completely randomized design, the results revealed that while drying temperature did not affect yields, it reduced the lightness (L*) of the cultivars. Among them, HRDI Sp-61 exhibited the highest protein content (6.35 g/100g, p ≤ 0.05), whereas HRDI Sp-72 showed the highest phenolic compound content (409.88 mg GAE/100 g powder), which was in line with DPPH antioxidant activity. All dried sweet potato extracts displayed antibacterial activity against Escherichia coli, with HRDI Sp-61 demonstrating the most significant inhibitory effects (10.50 and 10.07 mm zones of inhibition).
