Using deep learning to detecting abnormal behavior in internet of things

<span lang="EN-US">The development of the internet of things (IoT) has increased exponentially, creating a rapid pace of changes and enabling it to become more and more embedded in daily life. This is often achieved through integration: IoT is being integrated into billions of intelligent objects, commonly labeled “things,” from which the service collects various forms of data regarding both these “things” themselves as well as their environment. While IoT and IoT-powered decices can provide invaluable services in various fields, unauthorized access and inadvertent modification are potential issues of tremendous concern. In this paper, we present a process for resolving such IoT issues using adapted long short-term memory (LSTM) recurrent neural networks (RNN). With this method, we utilize specialized deep learning (DL) methods to detect abnormal and/or suspect behavior in IoT systems. LSTM RNNs are adopted in order to construct a high-accuracy model capable of detecting suspicious behavior based on a dataset of IoT sensors readings. The model is evaluated using the Intel Labs dataset as a test domain, performing four different tests, and using three criteria: F1, Accuracy, and time. The results obtained here demonstrate that the LSTM RNN model we create is capable of detecting abnormal behavior in IoT systems with high accuracy.</span>

A Survey on Imminent Effects of the COVID-19 on Chinese Students' Willingness of Studying Abroad

Since its outbreak in late 2019, the COVID-19 (the new coronavirus pandemic disease) has spread throughout the globe at an unexpectedly rapid pace. It brought severe negative effects to all walks of life, and this paper analyzes especially its impacts on Chinese students studying or planning to study abroad by sending out a survey. As the United States has become the country with most confirmed cases as well as most related deaths since May 27th, 2020, the survey mainly focused on the Chinese students planning to study in the U.S. It asked the respondents about their decisions regarding their plan of studying abroad, and the reasons behind them by different scales of significance. Considering that the questions of the survey are relatively detailed and that the number of respondents (269) is limited, this paper applied qualitative analysis to the study. The hypothesis is that students making different decisions (generally either choosing in-person study or virtual/online study) are impacted by different considerations, which is generally tested as effective. However, the epidemic-related elements are the most influential among all options for those who decide not to go abroad for their studies. The result of the study is partially consistent with the hypothesis that the number of students staying home exceeds that of students going abroad. There are also unexpected outcomes, including that the deteriorating U.S.-China relationship plays an overwhelming part in the avoidance of going to the States.

Potential Therapeutic Role of Pituitary Adenylate Cyclase-Activating Polypeptide for Dry Eye Disease

Dry eye disease (DED) is caused by a reduction in the volume or quality of tears. The prevalence of DED is estimated to be 100 million in the developed world. As aging is a risk factor for DED, the prevalence of DED is expected to grow at a rapid pace in aging populations, thus creating an increased need for new therapies. This review summarizes DED medications currently in clinical use. Most current medications for DED focus on stimulating tear secretion, mucin secretion, or suppressing inflammation, rather than simply replenishing the ocular surface with moisture to improve symptoms. We recently reported that the neuropeptide PACAP (pituitary adenylate cyclase-activating polypeptide) induces tear secretion and suppresses corneal injury caused by a reduction in tears. Moreover, it has been reported that a PACAP in water and a 0.9% saline solution at +4 °C showed high stability and achieved 80–90% effectiveness after 2 weeks of treatment. These results reveal PACAP as a candidate DED medication. Further research on the clinical applications of PACAP in DED is necessary.

Challenges for ethics committees in biomedical research governance: Illustrations from China and Australia

In this paper, the evolution of the ethics committees for health research, their history, membership, and function in China and Australia is described. Investigators in each country compared the history and governance of their ethical systems based on the published evidence rather than personal opinions. Similarly, examples of challenges were selected from the literature. In both countries, the aim was to maximize the social benefits of research and minimize the risk imposed on the participants. Common challenges include maintaining independence, funding and delivering timely ethical reviews of the research projects. These challenges can be difficult where research ethics committees rely on voluntary contributions and lack a strong resource base. They must adapt to the increasingly rapid pace of research as well as the technological sophistication. Population health research can challenge the conventional views of consent and privacy. The principles of the sound ethical review are common in both countries; governance arrangements and operational procedures, however, can differ, reflecting the cultural values and norms of their host countries and in respect of legal environments. By studying the evolution and function of ethics committees in the two countries, we established the differences in the governance and health systems, while similar ethical objectives helped sustain collaborative research.

Ecosystem Valuation of Agricultural Land Use Change

With the rapid pace of urbanization, land-use change is essential for economic and social progress; however, it does not come without costs. With such rapid urbanization, there comes pressure on the land and its resources, like that of food and timber production with a significant impact on the livelihood of millions of people. With the loss of agricultural land due to developmental activities, future agriculture would be very intensive. Therefore, it is likely with the existing pattern of allocating land uses for future development that we may lose the ecosystem services and highly productive agricultural lands. The value of these ecosystem services to agriculture is enormous and often underappreciated. The study focuses on identifying underlying causes of the land-use change, ecosystem services affected due to land-use change in peri-urban areas of Chandigarh using spatial mapping of affected ecosystem services and suggesting proposals for promoting agricultural ecosystem values using economically-informed policy instruments.

B Corp Certification Effects

Compliance with the Sustainable Development Goals (SDGs) and the 2030 Agenda represents a large investment that cannot be obtained solely through public resources. Therefore, it is necessary for the private sector to align itself with the SDGs and integrate them into its business model. In an attempt to align private interests with the SDGs, various impact measurement initiatives have emerged in recent years. However, none of them have been universally accepted, in part, because they still have weaknesses. As an alternative, some companies have chosen to become certified. The figures show that the B Corp certification is one of the most important ones internationally, since it has been growing at a rapid pace since its creation. In fact, there are currently almost 4,000 certified companies throughout the world. Despite this fact, there are very few studies which analyze the main effects of this certification yet. Therefore, the objective of this chapter is to validate a questionnaire that collects these effects through a Delphi study, formed by a panel of experts in the B Corp movement.

GIS and Geo-Positioning Developments in Coping With the Pandemic

This chapter deals with some technical aspects of the spatial strategy for overcoming the huge challenges posed by the pandemic. The focus of this chapter is to highlight the use of GIS tools and positioning technologies in diverse contexts to manage the threat of COVID-19. For this task, three stages of analysis are proposed. In a first preventive stage, some governments applied socioeconomic criteria drawn from existent statistical information to spatially identify the areas with a clear predisposition toward the accelerated spread of the contagion. In a second stage, when the pandemic fully reached a rapid pace of expansion and lockdown measures became necessary, the technologies helped to monitor the most affected areas and to establish a dashboard deployment for visualizing the severity of the catastrophe. In the third stage, after the establishment of control and mobility protocols, different governments resorted to mobile phone positioning as a resource for monitoring quarantine compliance and recognizing if social group behavior entailed any evident risk or spread.

e-HRM in a Cloud Environment

As the digitization of HR processes in companies continues to increase, at the same time, the underlying technical basis is also developing at a rapid pace. Electronic human resources (e-HRM) solutions are used to map a variety of HR processes. However, the introduction of such systems has various consequences, which are not only technical but also imply organizational and functional changes within the organization. Additionally, the cloud environment contributes to enhancing e-HRM capabilities and introduces new factors in its adoption. A systematic review of the available literature on the different dimensions of electronic resources management was conducted to assess the current state of research in this field. This review includes topics such as the evolution of e-HRM, its practical application, use of technology, implementation as well as HR analytics. By identifying and reviewing articles under e-HRM, IT technology, and HR journals, it was possible to identify relevant controversial themes and gaps as well as limitations.

KAJIAN SOSIAL KARYA SENI KRIYA KAYU DI DESA MULYOHARJO KABUPATEN JEPARA

The development of handicrafts in Indonesia is now experiencing such a rapid pace, especially those oriented to various modern technological facilities lately. Accompanying all human needs that are passive and have an active function, furniture or household furniture products are the main choice in various worlds of property today, both domestically and abroad. The relationship between craft art and several aspects that must be met shows the existence of a problematic in its embodiment. This is probably not realized by the kriyawan who appear instantly and oriented to a market. It's the same with craftsmen in Mulyoharjo Village, although there are those who have the idea of working through an artistic instinct and become unconventional craft craftsmen in their social community.
