    Container-Based Virtualization for Bluetooth Low Energy Sensor Devices in Internet of Things Applications
    (Univ Osijek, Tech Fac, 2021) Taskin, Deniz; Taskin, Cem; Yazar, Selcuk
    Internet of Things (IoT) has become a continuously growing concept with the developments of ubiquitous computing, wireless sensor networks (WSN). With the industry 4.0 revolution, all production activities such as logistics, finance, agriculture, energy and almost all the service and infrastructure applications used by people in the cities we live in will undergo a major change within the IoT paradigm. In this study, a prototype model has been developed and its performance is investigated. Our prototype model can reach the advertisement data of Bluetooth Low Energy sensor devices by using container-based virtualization technology and directly working at layer 2 (L2) of Transmission Control Protocol/Internet Protocol (TCP/IP). Virtualization mechanism for the sensor devices could help to exchange context-aware information with Internet Protocol Version 6 (IPv6) structure. Also with virtualization may emerge interoperable sensor node platforms of heterogeneous environments from different vendors.

    Developing a bluetooth low energy sensor node for greenhouse in precision agriculture as internet of things application
    (Lublin Univ Technology, 2018) Taskin, Deniz; Taskin, Cem; Yazar, Selcuk
    The Internet of Things (IoT) paradigm is referring to the underlying constituents of the 4th Industrial Revolution that will also affect the use of the Internet in industrial production in the future. More than 50 billion smart devices will be able to communicate with each other and internet services over the increasing network capabilities of wireless sensor networks nodes on IoT applications in the next ten years. One of the leading production areas using IoT within wireless sensor networks is precision agricultural practices. In this study, a new sensor node design, which includes ambient light and temperature sensors employing Bluetooth Low Energy (BLE) communication protocol, is used as an IoT application. Subsequent to this, sensor node power consumption and management cost was investigated. The experimental results show that the developed sensor node lifetime is about 8 years and the total cost of nodes and gateway model is under $50 per year per 0.1 hectare.

    The effect of using an interactive mobile application for the management of chemotherapy-induced nausea and vomiting in children: Randomized controlled study
    (Elsevier Sci Ltd, 2022) Semerci, Remziye; Kostak, Melahat Akgun; Taskin, Cem
    Purpose: This study was conducted to develop an interactive mobile application called 5inD, and investigate the effect of 5inD on the management of chemotherapy-induced nausea and vomiting (CINV) in pediatric oncology patients.Methods: The prospective, parallel-group and randomized controlled study was conducted in a university hospital between October 2019 and January 2021 with 57 children aged 8-18 years who were treated with chemotherapy and their mothers. In this study, a mobile application called 5inD was developed, which includes five distraction methods to reduce CINV. Data were collected about CINV through the Adapted Rhodes Index for Nausea & Vomiting child version (ARINVc), and parent version (ARINVp). CINV of the children was evaluated for seven days starting from the first day of chemotherapy.Results: In the study, Child ARINVc and Parent ARINVp mean scores of the intervention groups were lower than the control group during the seven days (p < 0.05). There was a statistically significant difference between the group's Adapted Rhodes Index of Nausea and Vomiting for Pediatrics by Child (ARINVc) and by Parent (ARINVp) mean scores in terms of the group, time, and group*time interaction. While a statistically significant difference was found between the intervention group's and control group's mean scores in terms of the group, time, and group*time for the acute CINV (p < 0.05), there was no statistically significant difference for delayed CINV between groups scores in terms of the time, and group*time interaction (p > 0.05).Conclusion: This study supports the findings that the interactive mobile application was found effective in reducing CINV in children. Additionally, it can be said 5inD is more effective for the management of acute CINV than delayed CINV.
