Human reproductive cloning involves making an entire cloned human instead of only cells or organs. This type of cloning may cause ethical problems – how to define their identity between real and cloned human beings; how do human beings treat artificial creatures in real society? Plus, it may also cause societal issues; for instance, whether this technology may be taken advantage of by capitalism for class solidification. Reproductive cloning is strictly prohibited in some countries. In recent years, some scientists have been encouraged to lose the restrictions on this research; however, the public has quite different attitudes toward cloning. This paper justifies that human cloning technology needs development with reasonable government restrictions.","PeriodicalId":309267,"journal":{"name":"International STEAM Communications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124898621","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}

{"title":"Explaining Dementia Using Graph Theory and Machine Learning","authors":"Jaeha Lee","doi":"10.37906/isteamc.2022.4","DOIUrl":"https://doi.org/10.37906/isteamc.2022.4","url":null,"abstract":"Dementia is a central nervous system neurodegenerative disease. Dementia has been discussed around different types. Among all, Alzheimer’s disease (AD) and vascular dementias (VaD) are the commonly caused disease. There is a huge research gap that graph theory has rarely been followed to explain the cognitive systems functioning particularly diseases like dementia. Thus, theoretical models of graphs can be used to interrogate the cognitive systems and the likely presence of dementia to understand the reasonings behind and thus the treatment. In this paper, three studies have been discussed in which dementia is investigated through graph theory and machine learning by using theoretical foundations to support the evidence. The first study discusses the significance of graph theory techniques and its coined ideas. There are fundamental designed parameters; connectivity, diameter vertex centrality, betweenness centrality, clustering coefficient, degree distribution, cluster analysis and graph cores. In addition to this, these are featured to analyze magneto-encephalography data to find out functional network intensity in Alzheimer’s disease affected patients. The second study explores particularly the changed structure of Alzheimer’s disease. The third study coins the significance of machine leaning philosophy that paves the way for the black box and diagnosis.","PeriodicalId":309267,"journal":{"name":"International STEAM Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116154305","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}

People nowadays need effortless services, and recommendation system is one of them. They are present and used everywhere, whether it's advertising, e-commerce or any other domain. Companies such as Netflix, YouTube, Amazon, Spotify rely on recommendation systems to boost their sales. Moreover, it increases the engagement of users with a particular app or website as it tends to show more relevant individualized content. It basically takes the user’s past history as an input and then using filtering techniques it predicts the most suitable item/content for the user as an output. The main objective of this paper is to predict movies most desired by the user with as much accuracy as possible. In this paper, I will provide a brief description of various filtering methods and the particular techniques that I used to achieve the desired result. I have used Tf-Idf to quantify the overview of the movies, then did a pairwise similarity for the Content Based Filtering. This allows the user to watch movies based on their watch history according to the plot of the movies. For Collaborative Filtering, I have used Matrix Factorization to generate real-time recommendations based on user-movie rating matrix. Correlation Coefficient is used to calculate the score. The higher the score, the more likely the movie is liked by the user. I have used the voting system for Hybrid Filtering. Weighted Rating Score is calculated with the help of the votes given to the movies by the users. Then a popularity feature is also used to generate more meaningful movie recommendations. MinMax Scalar is used to normalize the data, and then fifty percent priority is given to both Weighted Rating Score and popularity and a final score is calculated. Using this final score, popular or top movies are generated. The databases used are retrieved from MovieLens and Kaggle. Consequently, my proposed system will generate recommendations based on the plot of the movie using tf-idf and cosine similarity, based on user-movie rating matrix and correlation coefficient, based on voting and popularity basis.","PeriodicalId":309267,"journal":{"name":"International STEAM Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130394146","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}

Exercise has a lot of benefits. It increases your body HDL (good cholesterol), controls your weight, prevents heart attacks and diabetes, regulates blood pressure, strengthens your muscles, and improves mood. However, we have minimal information regarding the effects of parents’ exercise on the genes they pass down. This research paper reviews three different previous studies done on this topic. The first study is about the research done on the mice to analyze the transmission of the exercise effects of the mice fathers to offspring. The second study is the comprehensive analysis of the epigenetic changes at the molecular level in both mammalian and rodent cells. The third study is exclusively about the research on humans.

Depending upon the flex of the sensor, it produces a voltage output. To embed this in a forearm prosthetic, a piezoelectric sensor can be attached to the hinge joint. Hence, the more it moves, the more voltage output is produced. In this paper, a prosthetic limb is modeled as a physical pendulum. The experiment done includes a voltmeter, a physical pendulum, and a piezoelectric sensor attached to the axis. Due to the formula breakdown into a 2-parameter model, the chi-squared analysis on the formula is much simpler. Hence, the author could fit the model to the data and the best fit values were found.","PeriodicalId":309267,"journal":{"name":"International STEAM Communications","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132156764","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}

Additionally, they find that emotions are not limited to mammals, but that birds, reptiles, and fish also have feelings. Studying animal emotions may be the key to understanding creatures’ relationships with each other. In particular, what relationships do animals form when living in small groups? Ethologists observing animals in their natural habitats reveal many answers. First, animals in small groups employ a variety of leadership styles. Second, family relationships between parents and offspring, brother and sister, and elders and adolescents help the group survive and thrive. Third, when animals lose a member of their group, they appear to grieve in ways synonymous to humans. As they examine these relationships, animal behaviorists, including famed ethologist Marc Bekoff, help us dive deeper into the lives of animal communities so we can live with them in harmony with them.","PeriodicalId":309267,"journal":{"name":"International STEAM Communications","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131058031","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}
