It is also a major cause of premature death. However, previous studies inconclusively found that several factors were still unrelated particularly among female individuals. The objective of this unmatched case-control study was to investigate the factors that are correlated with high blood pressure of the female students in Sirindhorn College of Public Health, Khon Kaen.</p> <p><strong> Method:</strong> The samples of 102 female students were selected using a stratified randomization and divided into 2 groups. The ratio of cases to controls was 1:2 as follows. The case group and control group were 34 enrolled individuals with blood pressure ≥ 130/85 mmHg and 68 enrolled individuals with blood pressure &lt; 130/85 mmHg, respectively. Data were collected by a questionnaire (Cronbach’s alpha coefficient = 0.94), and the record of annual health checkup. Descriptive statistics and inferential statistics (multiple logistic regression analysis) were used to describe results of this study.</p> <p><strong> Results:</strong> After adjusted for the covariate, the results revealed that factors correlated with high blood pressure of the female students were monthly expenses ≥5,000 baht (OR<sub>adj</sub> = 3.19, 95% CI: 1.20 to 8.50 ; p-value = 0.020), high body mass index (OR<sub>adj</sub> = 6.20, 95% CI : 2.02 to 19.00 ; p-value = 0.001), and low level of exercise behavior (OR<sub>adj</sub> = 2.66, 95% CI : 1.01 to 7.06 ; p-value = 0.049).</p> <p> Therefore, there should be health promotion activities for female students by promoting physical exercise to prevent future occurrence of high blood pressure.</p> Wanasri Wawngam Sudarat Roenthaisong Lampung Vonok Supat Assana Kritkantorn Suwannaphant Copyright (c) 2022 Wanasri Wawngam, Sudarat Roenthaisong, Lampung Vonok, Supat Assana, Kritkantorn Suwannaphant 2022-06-10 2022-06-10 35 1 29 44 Immediate Effect of Facial Massage and Lymphatic Drainage Massage on Intraocular Pressure <p><strong>Abstract</strong></p> <p><strong> Objective</strong>: High intraocular pressure is one of the major causes leading to glaucoma and visual loss. Thus, maintaining normal intraocular pressure is very important to delay visual loss, so lowering the intraocular pressure is the main treatment. Relaxed muscles help increase lymph outflow around the face and head. It is possible to increase the aqueous humor outflow and reduce the congestion from facial muscles spasm, increase outflow of aqueous humor to vascular and lymphatic systems which result in a reduction of intraocular pressure. The objective of this study was to investigate the effect of muscle relaxing massage and facial lymphatic drainage on intraocular pressure.</p> <p><strong> Methods: </strong>Twenty two healthy volunteers aged 37.18+11.58 years who regularly work with computer display more than 4 hours per day were recruited. Each of them received the muscle relaxing massage and facial lymphatic drainage for 15 minute.</p> <p><strong><strong> Results</strong></strong>: The study results showed a significantly decrease in the mean difference of intraocular. In addition, the mean average of the reduction of intraocular pressure was significantly decreased 0.87+1.43 mmHg (p=0.01) for the right eyes. Nevertheless, no significant difference in the left eyes after receiving the intervention with mean 0.63<u>+</u>1.74 mmHg (p=0.105). These findings may conclude that the effect of massage to relax muscles and lymphatic drainage of muscle around the head and face might reduce intraocular pressure.</p> Pattrawan Pattaranit Tanapat Ratanapakorn Jirawat Limphatcharaporn Pairaya Sitthiracha Copyright (c) 2022 Pattrawan Pattaranit,,MD, Jirawat Limphatcharaporn , Dr. 2022-06-10 2022-06-10 35 1 45 59 Surveying and Analyzing Green Environmental Context in Nakhon Ratchasima City via Urban Forestry Approach <p><strong>Abstract</strong></p> <p><strong>&nbsp; &nbsp; &nbsp;Objective:</strong> This study purpose was to develop mechanisms for storing perennial data and green spaces. The study area is Nakhon Ratchasima Old Town, which spans 1,167 Rai, 1 Ngan, and 32 square wah.</p> <p><strong>&nbsp; &nbsp; &nbsp;Methods:</strong> The researchers created 4Rester, a mobile phone application that can used to collect data, perennial coordinates, species, size, quality, leaf photos, stems, blossoms, and fruits in order to establish an open data database. Data can be stored and accessed by all users via mobile phones.</p> <p><strong>&nbsp; &nbsp; &nbsp;Findings</strong>: The study region has 2,166 perennials, 29 types of 1.85 trees per acre, and 9.54 square meters of green space per person. Each species represents less than 12% of the total number of species. The carbon dioxide gazelle can reduce CO2 emissions by 0.34 tons per acre each year, which equates to one perennial for every 11.38 people.</p> <p>&nbsp; &nbsp; &nbsp;According to the Office of Natural Resources and Environmental Policy and Planning's recommendations, carbon dioxide gazelles should be reduced. The Ministry of Natural Resources and Environment estimates that service green spaces and urban environmental green spaces in Nakhon Ratchasima Old Town should reduce carbon dioxide emissions by at least 1.2 tons per acre, implying that more perennial plants are required. Plants number 3,169.</p> Siriwat Sarakhet Nithi Lisnund Nithi Lisnund Copyright (c) 2022 2022-06-10 2022-06-10 35 1 60 75 Reduction of Water Hammer Impact with Surge Tank <p><strong>Abstract</strong></p> <p><strong> Objective:</strong> To evaluate the difference in reducing the impact of water hammer with the surge tank application with and without a flexible diaphragm.</p> <p><strong> Methods:</strong> The water hammer were simulated from 0.5 HP water pump, head maximum to 20 meters and control valve to adjust the flow rate. The water flowed through the PVC main pipes with ½ inch, ¾ inch, and 1 inch pipe sizes. The length of the PVC main pipe was 4 meters each. The study results were collected from pressure values at the surge tanks. The surge tanks were made out of PVC pipes. The pressure reduction values were compared in with and without the flexible diaphragm. The surge tanks studied were available in ½-inch, ¾-inch, 1-inch, 1.5-inch, and 2-inch sizes. The lengths of the surge tanks were 50, 75, 100 centimeters and were tested at each size of the surge tanks.</p> <p><strong> Results:</strong> The water hammer pressure reduction efficiencies were 2%-5%, 7%-15%, and 20%-40% for ½ inch, ¾ inch, and 1 inch pipe sizes, respectively. These efficiencies were directly proportional to the diameters and lengths of the surge tanks, both without and with flexible diaphragm. The flexible diaphragm could reduce the pressure with the higher efficiency of 2%-7% than the without flexible diaphragm. Because of the water supply pipe sizes were inversely proportional to the pressure generated in the pipe system. Therefore, the sizes of the main water supply pipes affect the efficiency of reducing pressure. The water pressure reduction efficiencies were 20%-55%, 7%-29%, and 2%-10% for 1 inch, ¾ inch, and ½ inch of the main water supply pipe sizes, respectively. In addition, the design of the surge tanks length that took into account the energy loss due to friction in the pipelines could achieves the less maximum length of the surge tank than to ignore the loss of energy due to friction in the pipe.</p> Prayong Keeratiurai Cheevin Limsiri Patiparn Promdee Puriprapat Wijitrpattamawong Copyright (c) 2022 Prayong Keeratiurai, Cheevin Limsiri, Patiparn Promdee, Puriprapat Wijitrpattamawong 2022-06-10 2022-06-10 35 1 76 90 Automatic Fuel Dispenser Machine <p><strong>Abstract </strong></p> <p> <strong>Objective: </strong>To develop an automatic fuel dispenser machine using a microcontroller and display the payment system through the LCD screen for fuel demand in rural areas.</p> <p><strong> Methods:</strong> Designed and constructed the automatic fuel dispenser machine using a microcontroller for the fuel distribution system and the payment system are displayed through the LCD screen.
