One of the main problems is that the elderly being left alone spend their lives to do daily activities difficultly due to physical changes. For example, falls&nbsp;in the&nbsp;elderly are the most common accidents. Therefore the objectives of this research are (1) to develop an alarm and monitoring system for the elderly when the elderly have an accident or injury, and (2) to develop a WiFi network inside residences to bridge data communication between wireless sensing devices and the Raspberry Pi board used as a main controller. The wireless sensing devices used to detect abnormal and emergency situations included a fall detector with an accelerometer, a motion detector with a camera and a distance sensor, and an emergency push button. When emergency situations were detected according to the pre-defined conditions, i.e., falling or pressing an emergency push button, or no motion within some time intervals, the Raspberry Pi board sent an SMS to a caregiver automatically. The experimental results showed that the intended objectives were achieved when the alarm and monitoring system was tested in both simulation scenarios and real-world situations.</p> Kiattisin Kanjanawanishkul, Kanokwan Bunkon, Nawaporn Ladkeaw, Noppachai Khongcharern ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.tci-thaijo.org/index.php/TNIJournal/article/view/198035 Fri, 28 Jun 2019 00:00:00 +0700 Application of Lean Six Sigma in Wine Glass Manufacturing Industry https://www.tci-thaijo.org/index.php/TNIJournal/article/view/182329 <p>&nbsp; &nbsp; &nbsp; &nbsp; Manufacturing in today’s Glass Industry is rapidly changing as the result of the intense competition in the market nowadays.

The purposes of this research are to improve the inventory quantity to be suitable for customers’ demand, to reduce holding cost and to minimize the total inventory cost. In the past, the company operations didn’t have purchasing planning strategy in the case study, the purchasing would be ordered when the inventory level is 0 that result shortage spare parts sometimes and the company had the policy about the spare parts with a limited 5-years lifetime. There were 17 items or 80% of total expired spare parts value that would be taken for forecasting and purchasing planning in this case study. We propose a new strategy about applying a mathematical model for purchasing planning spare parts that minimize the total inventory cost by using a new safety stock (SS) and customers’ demand that is the most accurate forecasting method with the lowest Mean Absolute Deviation (MAD) from 5 forecasting methods: 1) Moving Average, 2) Single Exponential Smoothing, 3) Double Exponential Smoothing, 4) Holt-Winters Smoothing, 5) Monte Carlo Simulation. From experiments, 17 items of the spare parts were the most suitable with Moving Average, Single Exponential Smoothing and Double Exponential Smoothing Method. In addition, this study calculated the new safety stock level at 95% confident level for new purchasing planning next year. Finally, The results of this study were found that the mathematical model for purchasing planning spare parts, could prevent the inventory shortage, reduce holding cost and minimize the total inventory cost from the current purchases of all items by 8,384,223 baht or decrease the average cost of 493,189.59 baht/year that is 17.55%</p> Sasithorn Kitti-udomporn, Suwitchaporn Witchakul ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.tci-thaijo.org/index.php/TNIJournal/article/view/188606 Wed, 26 Jun 2019 00:00:00 +0700 Improving the Performance of an Image Classification with Convolutional Neural Network Model by Using Image Augmentations Technique https://www.tci-thaijo.org/index.php/TNIJournal/article/view/182318 <p>&nbsp; &nbsp; &nbsp; &nbsp; Image classification is one of the challenges for both humans and computers because it is a critical task. Researchers try to solve this task in many ways. In neural networks, Convolutional Neural Network (CNN) has been widely used for images recognition, images classifications, and objects detections. The process of CNN model includes training and testing. This paper aims to improve the performance of an image classification with Convolutional Neural Network model by using image augmentation technique and compare the accuracy of each technique. The dataset that we used in this paper was collected from Canadian Institute for Advanced Research (CIFAR-10) dataset which consists of a total of 60,000 images. The color images are of size 32x32 in 10 different classes. In the first stage, the 10- fold cross validation method is used to divide 50,000 images for training 300 rounds and 10,000 images for testing. In the second stage, in order to create artificial images, 10,000 images were randomly-selected from all categories and applied the image augmentation technique such as color adjustment, rotation, zoom, or flip image to the image. This image augmentations technique were randomly selected only one technique and applied to one image. The training images were 60,000 images in total; 50,000 images from the first stage plus 10,000 new images. Then the computer trained the images for 300 rounds. The evaluation shows that after using image augmentations technique by creating artificial images, the accuracy of Convolutional Neural Network model performs better from 84.79% up to 87.57%</p> Pimpa Cheewaprakobkit ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/4.0 https://www.tci-thaijo.org/index.php/TNIJournal/article/view/182318 Wed, 26 Jun 2019 00:00:00 +0700 Research Kaizen of Standardized Work Analysis with Motion Study by Time Prism Software (Case study: Textile Industry) https://www.tci-thaijo.org/index.php/TNIJournal/article/view/198060 <p>&nbsp; &nbsp; &nbsp; &nbsp; The purposes of this research were to reduce the cycle time by improving the standard work by using Video Analysis Technique and study of Motion study using Time Prism Software Ver.1.9.0. for improvement case study from the textile Industry by the production process of the sewing department.
