During the coronavirus desease 2019 (COVID-19) pandemic, athletes must be able to adapt to new habits, such as: social restriction, change of competition schedule, and sending back home. This situation has led to an 18.2% increase in sleep disturbances. This study aimed to look at the sleep duration of adolescent athletes during the COVID-19 pandemic and its impact on athlete’s health conditions. A total of 126 adolescent athletes from 15 sports were recruited in this cross-sectional study. Adequate sleep duration was assessed according to the American Academy of Sleep Medicine criteria. Data on health conditions, medical history, injury history, were taken using a questionnaire. Behavioral assessment was assessed through the strengths and difficulties questionnaire. About 80.2% of adolescent athletes had insufficient sleep, and there was a significant relationship between sleep duration and disease incidence with a relative risk (RR) of 3.31 (1.32-8.28) 95% convidence interval (CI). There was no significant relationship between adequate sleep duration and health conditions (p>0.05). Things that may be the cause of sleep disturbances; use of electronic devices (37.6%), environmental conditions (53.4%), and worry (9%). In the end, this indicates adolescent athletes face difficulties in achieving adequate sleep duration during this pandemic and a continuous surveillance system is needed to monitor athletes outside the dormitory.

Scholars used multiple variables in measuring innovation leadership due to the differences in concept and understanding of this leadership in different fields. We develop the instrument to fill in the gaps in academicians’ and scholars’ assessments pertaining to the concept of innovation leadership, especially in the sense of education. This paper aims to explain the instrument development and validation process of the face and content validity for the purposed dimensions and items. All the constructs were generated through a rigorous review of the literature. There were six experts involved in validating the face and content validity of this instrument. Content validity index (CVI) and Modified Kappa statistics were used. The cut-off point of all items was 0.8 which retained as a final instrument. Therefore, from the 58 items, four were deleted as it is not reached the level of agreement between all the experts. The final instruments for further validation consisted of 54 items which fell under eight dimensions, namely: i) Creative behavior; ii) Ideal influence; iii) Effective communication; iv) Empowerment and mentoring; v) Technical skills; vi) Entrepreneurship; vii) Opening behavior; and viii) Closing behavior were identified. Therefore, this instrument could be utilized for further validation.

COVID-19 paediatric cavity telecare system: a novel chain key generation and encryption scheme

10.11591/ijres.v11.i1.pp13-24
Joydeep Dey
In this unprecedented coronavirus crisis, telehealth had emerged as a substitute way of treatment. More specifically, paediatric children are at high risk of outside exposure now. Non critical children must be treated remotely through the tableware system. A key based secured online transmission of an intraoral image of the paediatric cavity has been proposed in this manuscript. A cavity is a dental disease occurring in children. It is mainly caused due to prolonged bacterial infections. Secured online transmission with respect to medical transactions is immensely required in telecare information systems (TIS). Data confidentiality factor is preserved with preference in this proposed technique. A parity based novel chain key (NCK) has been generated and diffused inside the intraoral paediatric cavity image. NCK generation scheme is so highly robust that it gives different combinations after each bit altering. Initial seeds are kept at the dentist and patients, to resist myriad attacks inside the wireless channel, especially during this COVID-19 period. Histogram, floating frequency, and autocorrelation were obtained with accuracy using the proposed technique. Effects were observed by flipping simultaneous bits of the initial key and results were highly acceptable. The time for the proposed key generation has been found to be 514.61 ms. The total cryptographic time has been noted as 3.5983 ms in this technique.

Hameed Pasha Mohammad , H. C. Hadimani , Udara Yedukondalu , Srinivasa Rao Udara
Growing endless demand for digital processing technology, to perform high speed computations with low power utilization and minimum propagation delay, the metal-oxide-semiconductor (MOS) technology is implemented in the areas of very large scale integrated (VLSI) circuit technology. But MOS technology is facing the challenges in linear scaling the transistors with different channel modelling for the present day microelectronic regime. Linear scaling of MOSFET is restricted through short-channel-effects (SCEs). Use of silicon N-channel double gate MOSFETs (DG MOSFETs) in present day microelectronic regime features the short channel effect of MOSFET through a reasaonable forward transfer admittance with the characteristics of varying input capacitance values ratio. In this research paper, a distinct ρ-based model is designed to simulate SCEs through the designed silicon N-channel double gate MOSFETs with the varying front and back gate doping level and surface regions to estimate the varying junction capacitances can limit the intrusion detection systems (IDS) usage in VLSI applications. Analytical model for channel length and simulated model for total internal device capacitance through distinct ρ-based model are presented. The proposed distinct ρ-based model is suitable for silicon nanowire transistors and the effectiveness of the proposed model is validated through comparative results.

An internet of things (IoT) irrigation system is challenged by several issues, such as cost, energy consumption, and data storage. This paper proposes a novel energy-efficient, cost-effective IoT system called "NewAgriCom" to monitor agricultural field water flow. NewAgriCom works with an embedded energy harvesting system, is an autonomous remote supervisory control and data acquisition (SCADA) based on a general packet radio service (GPRS) cellular network that effectively communicates irrigation field data to the Node.js server using SIM808 EVBV3.2 modem. In javascript object notation (JSON) format, data is transmitted over the hypertext transfer protocol (HTTP) protocol to the MySQL database. Then data are transferred to the proposed IoT platform, which gives us a hand to control actuators, visualise, store and download the data. NewAgriCom can significantly reduce water consumption. It can set a schedule to control water automatically at specific times in various modes, including normal, light, and deep sleep modes. It regularly provides the location, time, signal strength, and the state of actuators with the identifier of every device remotely on the IoT Platform.

Quality of life (QOL) is an individualized measure that reflects a person’s subjective feelings towards the different aspects of his or her life and incorporates them into his overall health evaluation. The WHOQOL-BREF is a QOL measurement tool that has been validated in worldwide and local studies, with good reliability and sensitivity. WHOQOL-BREF questionnaire was used to evaluate the QOL of 89 workers at a plastic factory in Selangor, Malaysia. These were compared using t-test and Spearman’s bivariate correlation test to assess for significant correlations and predictors of performance in the different domains. The performance of the sample, both overall and for individual domains, was significantly lower than reported in previous studies. Local workers, highly educated workers, workers with shorter employment, and workers who did not take overtime performed significantly better than their respective counterparts. Also, lower education, foreign nationality, longer employment at the factory, overtime, and crushing jobs were associated with lower QOL scores. Studies evaluating QOL in industrial workers in Malaysia are scarce. Our sample is more diverse than the previous similar studies from Malaysia, and hence it offers new insights into the QOL of plastic industrial workers in the country.

Office automation is the process using machines with the help of embedded computing perform the office activities and its tools and applications. The office automated using computer-aided processing stored, visual and audio data to simplify, improve, and automate the power saving and time management of the organization. A very important component of office automation concerns the automation of employee centred activities such as authentication, automatic alerting of appointments and automatic powering on/off personal computer. The employee image is captured using Java media framework, attendance records for all employees is gathered and processed automatically, and they can be accessed from the database on a monthly or weekly basis. The various software and hardware components of the system were developed and integrated to form the Exypnos Office System and validated on real life scenarios. Java proved to be a versatile platform for implementing a project of this nature with diverse requirements. Web camera interfacing and image capturing are implemented in the Java environment with the help of Java media framework (JMF). Java short message service (SMS) application programming interface (API) and Bluetooth technology is used for sending schedules through SMS. Radio frequency identification (RFID) systems use many different frequencies, but the most common and widely used and supported by our reader is 125 kHz. Office automation systems have more benefits to an organization. The project is implemented on MS Windows platform and in future can be implemented in Linux platform.

Gollangi Raju , Nagamalleswara Rao Kanidarapu
Exergy, one of the handed-down energy conservation techniques, which can obtain from thermodynamic laws (first and second), will disclose the work presented within the system, the amount of irreversibility as well as what are the possible ways to reduce inefficiencies in the system. This discourse mainly highlighted various techniques and possible methods for efficiency improvement in the organic Rankine cycle (ORC). That means mainly concentrated on following key parameters like the selection of working fluid, suitable expander, the different heat sources of an evaporator, and modifications in heat exchanger based on the application of ORC system through an exergy approach for better performance, decrease energy losses, and destruction rate. This review can help to pontificate for better-summarized results that were done before and suggest some ideas for how to select an optimized parameter for better efficiency and to decrease the destruction rate in the ORC system.

An efficient multi-level cache system for geometrically interconnected many-core chip multiprocessor

10.11591/ijres.v11.i1.pp93-102
Tirumale Ramesh , Khalid H Abed
Many-core chip multiprocessor offers high parallel processing power for big data analytics; however, they require efficient multi-level cache and interconnection to achieve high system throughput. Using on-chip first level L1 and second level L2 per core fast private caches is expensive for large number of cores. In this paper, for moderate number of cores from 16 to 64, we present a cost and performance efficient multi-level cache system with per core L1 and last level shared bus cache on each bus line of a cost-efficient geometrically bus-based interconnection. In our approach, we extracted cache hit and miss concurrencies and applied concurrent average memory access time to more accurately determine the cache system performance. We conducted least recently used cache policy-based simulation for cache system with L1, with L1/L2, and with L1/shared bus cache. Our simulation results show that an average system throughput improvement of 2.5x can be achieved by using system with L1/shared bus cache system compared to using only first level L1 or L1/L2. Further, we show that the throughput degradation for the proposed cache system is only within 5% for a single bus fault, suggesting a good bus fault tolerance.

Customization of GPRS, and Wi-Fi device drivers for PXA270 of Linux OS based barcode scanner

10.11591/ijres.v11.i1.pp84-92
Prabhakar Pujeri , Sanket S. Naik Dessai
To access any device, it is necessary to have an access point. A device driver is an entry point to access a device. This project is aimed to customize the Wi-Fi and general packet radio service (GPRS) device drivers in Linux OS for PXA270 (Intel Xscale ARM processor). Customizing a device driver is a special way of designing software that can be more easily ported from one architecture to another without rewriting it from scratch. The paper is discussing about the customisation of Wi-Fi and GPRS device driver in Linux OS for PXA270 (Intel Xscale ARM processor). To develop a device driver, it is necessary to understand the processor architecture and Linux kernel internals and other design constraints. Since dynamically loaded driver module is attached to the existing kernel, and any error in the driver will crash the entire system. Resource allocation and implementation for a device is one of the main concerns for device driver developers. The device resources are input/output, memory, IRQs and ports. The required toolchain to build the cross-complier for the Intel Xscale ARM processor was built on Linux platform. The customised device drivers of Wi-Fi, and GPRS was customised, and the customised images are made to port for PXA270 processor architecture on EMX-270 board. With all the supporting parameters the kernel images with drivers are build and ported efficiently. Also, a successful verification and testing had been performed for their functionalities.

10.11591/ijeecs.v25.i3.pp1712-1722
Hossam Elzayady , Mohamed S. Mohamed , Khaled M. Badran , Gouda I. Salama
Recent studies show that social media has become an integral part of everyone's daily routine. People often use it to convey their ideas, opinions, and critiques. Consequently, the increasing use of social media has motivated malicious users to misuse online social media anonymity. Thus, these users can exploit this advantage and engage in socially unacceptable behavior. The use of inappropriate language on social media is one of the greatest societal dangers that exist today. Therefore, there is a need to monitor and evaluate social media postings using automated methods and techniques. The majority of studies that deal with offensive language classification in texts have used English datasets. However, the enhancement of offensive language detection in Arabic has gotten less consideration. The Arabic language has different rules and structures. This article provides a thorough review of research studies that have made use of artificial intelligence (AI) for the identification of Arabic offensive language in various contexts.

This paper presents the characteristic of the positive attempted leaders preceded by positive narrow bipolar pulses (NPBPs). Attempted leaders are the preliminary breakdown process with no subsequent event (return stroke). On the other hand, narrow bipolar pulse is the lightning event commonly isolated and produces a strong electromagnetic field (in a short period). Attempted leaders hardly occurred in the tropics, and the preceding of the NBP (the combination) should be considered unique. In this present study, we found four samples in which the arithmetic means of duration of NPBPs pulse was 32.19 µs, with separation between the positive attempted leader was 1.86 ms apart. For the positive attempted leader, the arithmetic means of the whole pulse train, individual pulse and interval pulse of positive attempted leaders were 3.47 ms, 29.66 µs and 486.53 µs, respectively. The pulse train in this study seems to fade out fast compared to the isolated positive attempted leader pulse train. Next, the NPBP's pulse duration in this study shows well in agreement with the type of isolated NPBPs indicates that the association does not affect its pulse duration characteristic already present in the title.
