Although various approaches have been implemented globally for indoor and outdoor agricultural (agri-) working sites, there is room for improvement. In this study, we aim to adapt these approaches particularly for real agri-directors, leaders and managers to improve the quality of tasks and their security levels. Thus, we apply a deep learning-based method and qualitatively demonstrate the classification of physical timeline datasets. To create our dataset, our subjects were six experienced agri-manual workers and six completely inexperienced men. The targeted task was cultivating the semi-crunching position using a simple, Japanese-style hoe. We captured the subjects’ acceleration and angular velocity data from an integrated multi-sensor module mounted on a wood lilt 15 cm from the gripping position of the dominant hand. We used Python code and recent distributed libraries for computation. For data classification, we successively executed a Recurrent Neural Network (RNN), which we evaluated using wavelet analyses such as the Fast Fourier Transform (FFT). These methods of analyzing digital data could be of practical use for providing key suggestions to improve daily tasks.","PeriodicalId":13816,"journal":{"name":"International Journal of Bioscience, Biochemistry and Bioinformatics","volume":"30 1","pages":"84-93"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82774303","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}

Still, better algorithms and methodologies can achieve even greater success with implication across a diverse range of biological and medicinal fields such as protein function inference. Accurate prediction methods rely heavily on sequence similarity, however structure is more evolutionary conserved, i.e. structure is an alternate characteristic for ancestral relationships between proteins. The premise of this work is that similar structural features will be clustered together, which may show a unique amino acid and secondary structure (SS) distribution, which can be, incorporated into HMMs for SS prediction and protein function inference algorithms. With structural-evolutionary relationship in mind, I propose a methodology for ‘structure’ based SS prediction methods using HMM and k-mean and fuzzy k -means fragmented protein clusters. When fragment distributions were incorporated into HMMs, the average accuracy increased by 1 percent but showed an increase in accuracy of up to 13 percent for particular sequences. The HMM results were not so promising, however the clustering of protein structure fragments by C-alphas bond angles shows to be a useful length-independent metric for inferring functional relationships between proteins.","PeriodicalId":13816,"journal":{"name":"International Journal of Bioscience, Biochemistry and Bioinformatics","volume":"10 1","pages":"74-83"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89564584","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}

Kitam.) is an Assam tea which is mainly found in northern Thailand. Fermented Miang is made from young and semi-mature Miang leaves by the local wisdom. Briefly, Miang leaves are harvested and steamed for approximately 2 hours prior to cooling down and subsequently packed into a container with close lid. Fermentation process will take place and run for 1-3 months normally. Steaming step renders a high quantity of steamed Miang juices (SMJ) which will be discarded afterwards. Evaluation of this biological waste will bring about ways of making value-added products. The purpose of this study aims to investigate the effects of steaming time and ages of Miang leaves on biological activities of SMJ obtained. Fresh, young and semi-mature, Miang leaves were collected and steamed for 30 minutes, 1, 2 and 3 hours. Meanwhile, young and old Miang leaves were steamed for 2 hours as compared with the conventional method. All SMJ were further evaporated and lyophilized to obtain SMJ crude extracts (CE). The 3-hour SMJ-CE had the highest antioxidant activity and total phenolic content (p<0.05), 548.4±13 μg GAE/ g extract and 460.24±11.8 μg GAE/g extract, respectively. Comparing between SMJ-CE of young and old Miang leaves, the antioxidant activity and total phenolic content of the young leaves SMJ-CE was significantly higher than the old leaves SMJ-CE (p<0.05). Moreover, all SMJ-CE had antibacterial activities to inhibit growth of some gastrointestinal pathogenic bacteria including Bacillus cereus, Escherichia coli, Escherichia coli O157:H7, Salmonella Typhi, Shigella dysenteriae, Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA) and Vibrio cholerae with the young leaves SMJ-CE showed the highest activities. The information obtained will be further used as a guideline in food and cosmetic application using SMJ-CE as a raw material.","PeriodicalId":13816,"journal":{"name":"International Journal of Bioscience, Biochemistry and Bioinformatics","volume":"1 1","pages":"66-73"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88969214","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}
