Kondo, K. Tungpimolrut","doi":"10.48048/WJST.2021.10573","DOIUrl":"https://doi.org/10.48048/WJST.2021.10573","url":null,"abstract":"Lung diseases are now the third leading cause of death worldwide because of the many risk factors we are exposed to daily, such as air pollution, tobacco use, viruses (such as COVID-19), and bacteria. This work introduces a new approach of the 3D Active Contour Model (3D ACM) to estimate an inhomogeneous motion of lungs, which can be used to analyze lung disease patterns using a hierarchical predictive model. The biophysical model of lungs consists of End Expiratory (EE) and End Inspiratory (EI) models, generated by high-resolution computed tomography images (HRCT). A proposed technique uses the 3D ACM to estimate the velocity vector by using the corresponding points on the parametric surface model of the EE model to the EI model. The external energy from the EI models is the external force that pushes the 3D parametric surface to reach the boundary. The external forces, such as the balloon force and Gradient Vector Flow (GVF), were adjusted adaptively based on the Zaratio which was calculated from the ratio of the maximum value of EI to EE on the Z axis. Next, the feature representation is studied and evaluated based on the lung structure, separated into five lobes. The stepwise regression, Support Vector Machine (SVM), and Artificial Neural Network (ANN) techniques are applied to classify the lung diseases into normal, obstructive lung, and restrictive lung diseases. In conclusion, the inhomogeneous motion pattern of lungs integrated with medical-based knowledge can be used to analyze lung diseases by differentiating normal and abnormal motion patterns and separating restrictive and obstructive lung diseases.

The classes have been suspended since 16 March 2020 to slow down the COVID-19 disease spread, and the students are suggested to study online at home. The present study intends to understand the at-home activities and well-being of foreign students. A web-based survey was conducted from 22 through 23 March 2020 to record the activities and well-being of the students on 20 and 21 March 2020. Happiness and stress levels with the seven-points Likert scales were considered as the two output variables (1 = lowest and 7 = highest). The ordered probit model was applied to develop the subjective well-being models, taking into account at-home activities. The results highlighted that students who were happier were more likely to study for longer at home, but that studying for longer increases stress levels. Students who were less happy and more stressed were more likely to speak on the phone for longer, while doing exercise at home for longer increased the likelihood of happiness. This paper contributes to a better understanding of at-home activities associated with well-being of foreign students in Thailand during the COVID-19 outbreak.","PeriodicalId":38275,"journal":{"name":"Walailak Journal of Science and Technology","volume":"17 1","pages":"1024-1033"},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44884850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It also emphasizes parameters like data variety and velocity data. Big data will play a most significant role in our daily life regarding applications like healthcare electronic commerce, agriculture, telecommunication, government, and financial trading. In the agriculture domain, big data is an optimal method to increase the productivity of farming by gathering and processing information like plant growth, farmland monitoring, greenhouse gases monitoring, climate change, soil monitoring and so forth. Virtualization is an emerging technique that can be combined with big data in agriculture. Virtualization has been used extensively in research for a long time, the term “virtual” entities affecting a real-life form. In agriculture, it has many more physical objects, sensors, and devices. This physical object is virtualized and has digital representation to store, communicate and process via the internet. The information from the virtual object has a large volume of data which helps meaningful data analysis or aspects to make application services like decision making, problem notification, and information handling. This paper provides a comprehensive review of big data virtualization in the agriculture domain. The virtualization methodology, and tools used by many researchers is surveyed.","PeriodicalId":38275,"journal":{"name":"Walailak Journal of Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66681026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that employees and their clients mostly communicate via email. Therefore, crucial business data are conveyed in email contents. Whenever employees need to find information, the first place they look for such data is email. The owners of businesses are concerned about this issue, so they proposed to buy a new workflow management system to help in managing their business transactions. The difficulty of implementing the new workflow management system is in migrating existing emails into the system. A new workflow management system should also be able to classify any incoming emails into categories. The researchers noticed that there were some keywords that frequently occurred in email contents in the same categories. Therefore, the researchers implemented a program to categorize the emails based on the words found in email messages. There are 2 parameters which affect the accuracy of the program. The first parameter is the number of words in a database compared to the sample emails. The second parameter is an acceptable percentage to classify emails. The results of this research demonstrated that the number of words in a database compared to the sample emails should be 9, and the acceptable percentage to categorize emails should be 30 %. When this rule was applied to categorize 8,751 emails, the accuracy of this experiment was approximately 73.6 %. The next phase is to order emails in each category based on their characteristics. Finally, the program extracts essential data from structured emails and prepares them for the new workflow management system.","PeriodicalId":38275,"journal":{"name":"Walailak Journal of Science and Technology","volume":"14 1","pages":"783-790"},"PeriodicalIF":0.0,"publicationDate":"2017-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66681005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
