Developing conceptual understanding of angular momentum by hands-on activities |
This study aims to develop learning achievement, to enhance normalized gain and to develop concepts of angular momentum. The study was conducted with grade-11 students ( N= 34) from Buntharikwittayakarn School, Ubonratchathani. This study was a one group pretest-posttest design. Research tools included learning plans , two-tier diagnostic learning achievement test and handson activities. Hands-on activities help to learning by doing , discussion , group comments and construction. Data were analyzed into mean ,percentage ,standard deviation ,t-test ,and the normalized gains . The results show that the students’ average prost-test score was higher than the pretest score with statistical significance at .05 levels. The normalized learning gain was 0.59 which was at the medium gain level. The percentages of the students good conception understanding in pre-test and post-test were 20.29% and 62.94%, respectively. Their percent of the conception understanding was increased 42.65%. |

Developing conceptual understanding on projectile motion by using active learning approach |
The purposes of this research were (1) to develop the students’ learning achievement (2) to develop the students’ conceptual understanding and (3) to study the students’ learning gain on projectile motion by using active learning approach. The samples of this research were 41 grade 10 students from Suratthani School in the second semester of the 2016 academic year. By using one group pretest posttest design. The authors have designed activities to enhance the understanding of projectile concept emphasizing a constant acceleration in vertical and a constant velocity in horizontal. The research tools used in this study were lesson plans on projectile motion by using active learning approach, Two-tier diagnostic learning achievement test and students’satisfaction questionnaire. The data were analyzed into the average, percentage, standard deviation, t-test and normalized gain. The result showed that average achievement score was increased with statistically significant level of .05, the students’ post-instruction was significantly higher than their per-instruction and The students' learning advancement was 0.42 which was in a medium level. The result indicated that active learning activities can be used to develop student conceptual understand about projectile motion because the students can learn and construct knowledge with the active learning approach. |

value='value='Determination of antioxidant activities and total phenolic compound of Germinated brown rice'' |
value='value='In this study, the antioxidant activities and total phenolic compound of germinated brown rice were evaluated. The eight type rice samples were extracted by hexane, ethyl acetate and methanol. Antioxidant activity using DPPH Radical Scavenging Activity (DPPH assay) and Ferric Reducing Antioxidant Power (FRAP assay). Total phenolic compound was measured by Folin-Ciocalteu method. The antioxidant activities obtained from DPPH assay clearly indicate that methanol crude extract of Mali Dang germinated brown rice shows highest antioxidant activity with 95.45 %. For the FRAP assay, methanol crude extract of Mali Dang germinated brown rice shows highest value with 1,111.15 mg. Moreover, the results obtained from total phenolic compound of crudes extract by Folin-Ciocalteu reagent. The results show that the methanol crude extraction of Mali Dang germinated brown rice is highest total phenolic content with 408.85 mg. '' |

A Study of Noise Levels, Frequency Analysis and Noise Induced Hearing Loss In The Garment Factory |
The descriptive study was conducted to describe the noise levels, frequency analysis and noise induced hearing loss in the Garment factory. Data were collected from 10 production line by using sound level meter and 37 workers by using 5-minute hearing test questionnaire of Chicago Hearing Society. The results showed that noise exposure for an 8-hour workday was found to be 70.90 - 76.00 dBA which was lower than the noise level standards, setting at 8 5 dBA by the Department of Labor Protection and Welfare and the noise frequency from 10 production line were in range of 1,000 Hz., 2000 Hz. and 4,000 Hz. The Pearson chi - square test is used for testing relationships between working factors and the questionnaire to assess hearing was determined and found that average working hours per day and a negative history of noise exposure was statistically significant (p-value = 0.004 and 0.028) respectively. The result from questionnaire to assess hearing found that 2 workers had a hearing score at 32 - 42 points and 1 worker had a hearing score at 43 - 60 points. Comparing this score with the criteria of Chicago Hearing Society, it was found that hearing loss of the workers were categorize as severe-to-profound hearing loss. However, hearing test and hearing loss solution were probably needed for those workers. Moreover, those questionnaires were use as screening study. Thus, health check-up for hearing loss testing should be carried out among those workers. From the results of this study, it was suggested that the monitoring of occupational hearing loss, should be promoted and programmed for employees. Prevention of noise exposure and the use of personal protective equipment for reduce the risk of noise induced hearing loss. |

Automatic Matching System For Trading Agricultural Product''' |
This system has been developed which can operate on both the Android and iOS operating systems. They were developed by Vue.JS and MongoDB. Application which can facilitate agriculturists in the trading of 10 types of Agricultural Product. For examples Waxy Corn, Sweet Corn, Garlic, Chili, Pumpkin, Onion, Tomato, Lettuce, Yard Long Beans and Fragrant Flower. The system composed of the automatic Price Matching System that help agriculturists gain proper price and useful information according to customer’s need. This system used many factors such as price, quantity, transportation distance and satisfaction rating for selecting the agricultural product. And the system also provides useful information (ex. price and period) to clarify and notify general product’s price which in turn help the agriculturists make real-time decision when prices meet their need. For experimental result, we divided experimental into two sets: First, we validated the correct of function based technique using Black Box Testing Method. The results have confirmed application can work accurately. Second, we conducted experiment measuring by user satisfaction based on Likert Type Scale and we found that 12 users rated the result score were 4.02 (S.D=0.61) respectively. |

A study of the High Heel Height and the Indication of Varicose Veins in Female Students, Program in Hotel Management, Ubon Ratchathani University |
This cross-sectional survey research purposed to study of the high heel height and the indication of varicose veins in female students, Program in hotel management, Ubon Ratchathani were a 3rd year student of 113 people. The results showed that mean age was 21 years (51.3%). The most of wearing the shoes was moccasins that not more than height equal 1 inches (32.7%) and measure the high heel height 1.50 inches (56.6%). Results of the relative contribution of personal factors and indication of varicose veins were not statistically significant (p-value>0.05). Wearing shoes information consist of leg and ankle swelling, leg and ankle cramp, leg and ankle fatigue, leg and ankle itching or irritation and duration of the activity, stand, walk, in 1 days were statistically related to the level of symptoms and signs (p-value<0.05). Wearing shoes information consist of pain in the leg, pain in the legs or ankles and leg and ankle swelling were statistically related to the level of symptoms and signs (p-value<0.05). Therefore, there should be training and knowledge about ergonomics, the dangers of high heels that affect your health and activities that may create a risk while wearing high heels. |
