Impact of Cyber Relational Addiction on Undergraduates’ Interpersonal Relationship in Nigeria

Abstract: The upsurge in the use of cyberspace in recent years has led to pathological use for some individuals especially in the area of cyber relational addiction. This study aimed to investigate the influence of cyber relational addiction on interpersonal relationships and how variables of age, religion, levels of study, and gender of respondents moderate the influence of cyber relational addiction on their interpersonal relationships. This study employed a descriptive survey research design and administered a self-designed questionnaire on 420 randomly selected undergraduates from seven faculties at the University of Ilorin. A research question was answered in this study, while the hypotheses were also tested at 0.05 levels of significance. The varying collected data were analyzed using t-test and Analysis of Variance (ANOVA) statistical methods. Undergraduate students’ sources of information were mostly from the Internet than interacting with people, and they believed gaining more academically online than interacting with people. Meanwhile, the results were not varied based on the respondents’ age, levels of study, religion, and gender. It is necessary to develop a sound and wide range of activities that will reduce cyber relation addiction, which in turn promote psychological wellbeing among undergraduates. Interpersonal relationship skills training should be conducted for cyber-addicted adolescents to observe its impacts on cyber relational addiction.

Sehingga kita perlu mengembangkan berbagai kegiatan untuk mengurangi kecanduan berinteraksi menggunakan ruang siber, yang nantinya akan meningkatkan kondisi psikologis para mahasiswa. Selain itu, pelatihan keterampilan yang berhubungan dengan hubungan interpersonal harus juga diselenggarakan untuk mengetahui dampaknya pada para remaja dengan kecanduan untuk berinteraksi di ruang siber.
Low-cost, Light-weight Scalable Soft Data Glove for VR Applications

In the new coming era of metaverse, natural and continuous interactions between human beings and XR devices is vital. Yet, the current rigid wearable devices come with bulky occupation, heavy weight, and high cost. Herein, based on thermal transfer printing techniques, we proposed a more skin-compatible soft electronic glove with low cost ($\sim {\$}13.5$ per unit), light weight (~25.5g), and scalability for mass production. Through monitoring bending states of five fingers, the electronic glove can recognize hand gesture, and, as a demonstration, control a customized VR shooting game.
Phytosynthesis and Characterization of TiO2 Nanoparticles using Diospyros ebenum Leaf Extract and their Antibacterial and Photocatalytic Degradation of Crystal Violet

Abstract Crystalline anatase titanium dioxide (TiO2) nanoparticles (NPs) were prepared by eco friendly, facile and green synthesis of Diospyros ebenum leaf extract as reducing agent and were reported for the first time. The crystallization nature, morphology of the particles, and stability of the nanoparticles were investigated at different calcinations temperatures. The synthesized TiO2 NPs were investigated for the performance of photodegradation of crystal violet (CV) dye under UV light irradiation. Effects of temperatures on structural properties, photocatalytic activity, and the antibacterial activity of TiO2 NP were evaluated. This study revealed that TiO2 NP synthesized at 600 °C exhibited high photocatalytic efficiency and dye adsorption capacity when compared to other synthesized TiO2 NP and exhibited excellent antibacterial activity.
Main Line Fault Localization Methodology in Smart Grid – Part 2: Extended TM2 Method, Measurement Differences and L1 Piecewise Monotonic Data Approximation for the Overhead Medium-Voltage Broadband over Power Lines Networks Case

Enriching the fault identification methodology of the first paper, this second paper investigates the performance of the identification of main distribution line faults when broadband over power lines (BPL) networks are deployed. The main issue that is concerned in this paper is the impact of measurement differences on the fault identification process performance. The main contribution of this paper, which is focused on the identification of the main distribution line faults when measurement differences occur, is the application of the L1 piecewise monotonic data approximation (l1PMA) in order to cope with the measurement differences that influence the reflection coefficients derived from the extended TM2 method. Through the L1PMA application, measurement differences are confronted in order to prevent the trigger of a false alarm about the existence of a main distribution line fault. The combined operation of the extended TM2 method and L1PMA concludes the introductory phase (fault identification) of the main line fault localization methodology (MLFLM).
Hydrodynamic Behavior of Self-Propelled Particles in a Simple Shear Flow

The hydrodynamic properties of a squirmer type of self-propelled particle in a simple shear flow are investigated using the immersed boundary-lattice Boltzmann method in the range of swimming Reynolds number 0.05 ≤ Res ≤ 2.0, flow Reynolds number 40 ≤ Rep ≤ 160, blocking rate 0.2 ≤ κ ≤ 0.5. Some results are validated by comparing with available other results. The effects of Res, Rep and κ on the hydrodynamic properties of squirmer are discussed. The results show that there exist four distinct motion modes for the squirmer, i.e., horizontal mode, attractive oscillation mode, oscillation mode, and chaotic mode. Increasing Res causes the motion mode of the squirmer to change from a constant tumbling near the centerline to a stable horizontal mode, even an oscillatory or appealing oscillatory mode near the wall. Increasing the swimming intensity of squirmer under the definite Res will induce the squirmer to make periodic and stable motion at a specific distance from the wall. Increasing Rep will cause the squirmer to change from a stable swimming state to a spiral motion or continuous rotation. Increasing κ will strengthen the wall’s attraction to the squirmer. Increasing swimming intensity of squirmer will modify the strength and direction of the wall’s attraction to the squirmer if κ remains constant.
WIDE-ANGLE FREQUENCY SELECTIVE SURFACE WITH ULTRA-WIDEBAND RESPONSE FOR AIRCRAFT STEALTH DESIGNS

An ultra-wideband frequency selective surface (FSS) for wide incident angles is proposed. Its −3 dB bandwidth is from 3.49 GHz to 12.13 GHz, and the fractional bandwidth exceeds 110%. Some parasitic patches are appended to reduce the deviation of resonant frequency under wide-angle incidence. The proposed FSS exhibits an improved stability when the incident angles are in the range from 0◦ to 60◦. The relative simulated and measured results are provided to validate its effectiveness.
Research on Discourse Reconstruction Effect of Animated Film Cross-Cultural Communication Based on Machine Learning

Animated films are an important carrier of cultural dissemination, a way of conveying national culture and displaying regional culture in film and television, and an important medium for constructing national image and cultural form in the process of cross-cultural dissemination. The special film language expression of emotion in animated films also highlights its unique charm, status, and cultural communication role in the field of communication and at the same time reflects the unique value of the flash point in the ever-changing modern society. This paper starts with the related concepts of machine learning models, analyzes machine learning characteristics and model quality factors, and builds a model evaluation index system based on this and then proposes machine learning model evaluation implementation and index data processing methods. In building the corresponding evaluation experiment, the training model and animation film sentiment classification analysis need big data animation film culture data; the existing open source experimental data is very small and not suitable for the experiment of this paper. The principle of support vector machine is mainly introduced. And an improved machine learning model for animated film cultural sentiment classification is built. Experiments show that the performance of each index of the improved machine learning model is better than that of the support vector machine classifier.
Degradation by Electron Beam Irradiation of Some Composites Based on Natural Rubber Reinforced with Mineral and Organic Fillers

Composites based on natural rubber reinforced with mineral (precipitated silica and chalk) and organic (sawdust and hemp) fillers in amount of 50 phr were obtained by peroxide cross-linking in the presence of trimethylolpropane trimethacrylate and irradiated by electron beam in the dose range of 150 and 450 kGy with the purpose of degradation. The composites mechanical characteristics, gel fraction, cross-linking degree, water uptake and weight loss in water and toluene were evaluated by specific analysis. The changes in structure and morphology were also studied by Fourier Transform Infrared Spectroscopy and Scanning Electron Microscopy. Based on the results obtained in the structural analysis, possible mechanisms specific to degradation are proposed. The increasing of irradiation dose to 450 kGy produced larger agglomerated structures, cracks and micro voids on the surface, as a result of the degradation process. This is consistent with that the increasing of irradiation dose to 450 kGy leads to a decrease in crosslinking and gel fraction but also drastic changes in mechanical properties specific to the composites’ degradation processes. The irradiation of composites reinforced with organic fillers lead to the formation of specific degradation compounds of both natural rubber and cellulose (aldehydes, ketones, carboxylic acids, compounds with small macromolecules). In the case of the composites reinforced with mineral fillers the degradation can occur by the cleavage of hydrogen bonds formed between precipitated silica or chalk particles and polymeric matrix also.
The Role of Mitochondrial Metabolism, AMPK-SIRT Mediated Pathway, LncRNA and MicroRNA in Osteoarthritis

Osteoarthritis (OA) is the most common joint disease characterized by degeneration of articular cartilage and causes severe joint pain, physical disability, and impaired quality of life. Recently, it was found that mitochondria not only act as a powerhouse of cells that provide energy for cellular metabolism, but are also involved in crucial pathways responsible for maintaining chondrocyte physiology. Therefore, a growing amount of evidence emphasizes that impairment of mitochondrial function is associated with OA pathogenesis; however, the exact mechanism is not well known. Moreover, the AMP-activated protein kinase (AMPK)–Sirtuin (SIRT) signaling pathway, long non-coding RNA (lncRNA), and microRNA (miRNA) are important for regulating the physiological and pathological processes of chondrocytes, indicating that these may be targets for OA treatment. In this review, we first focus on the importance of mitochondria metabolic dysregulation related to OA. Then, we show recent evidence on the AMPK-SIRT mediated pathway associated with OA pathogenesis and potential treatment options. Finally, we discuss current research into the effects of lncRNA and miRNA on OA progression or inhibition.

1Human Nutrition Unit, School of Public Health, Dilla University, Dilla, Ethiopia; 2Department of Population and Family Health, College of Health Sciences, Jimma University, Jimma, Ethiopia Purpose: Treatment at a stabilization center is an important intervention to avert the huge burden of mortality for children with complicated severe acute malnutrition (SAM). Despite the improvement in hospital coverage and the development of standardized WHO treatment guidelines, recent reviews indicated a wide range in recovery rate (34–88%) due to several contextspecific factors. This study aimed to estimate time to recovery and to determine predictors of time to recovery among children aged 6–59 months with severe acute malnutrition. Patients and Methods: An institution-based retrospective cohort study design was used among 375 children aged 6–59 months admitted to Jimma University Medical Center, Jimma, Ethiopia from September 2015 to September 2017. All eligible children were enrolled and assessed using a pretested questionnaire. Kaplan–Meir estimates and survival curves were used to compare the time to recovery using log rank test among different characteristics. Cox proportional hazard model was used to identify significant predictors of time to recovery. A p-value less than 0.05 was declared statistically significant. Results: The rate of recovery was 4.06 per 100 person days. Median time of recovery for our cohort of SAM children’s was 19 days (95% CI: 17.95–20.05). Independent predictors of time to recovery were play stimulation (AHR=1.93, 95% CI: 1.23–3.03), vaccination status (AHR=2.26, 95% CI: 1.12–4.57), tuberculosis (AHR= 0.48, 95% CI: 0.27–0.87), malaria (AHR=0.34,95% CI:0.13–0.88), use of amoxicillin (AHR=1.54, 95% CI: 0.008–2.34), deworming (AHR=1.8, 95% CI: 1.18–2.73), and shock (AHR=0.18, 95% CI: 0.05–0.59). Conclusion: The findings of this study showed that the average length of stay on treatment and median time for recovery are within the sphere standard. Psychosocial stimulation, appropriate provision of routine medication and management of medical co-morbidity are needed to promote fast recovery.
An Efficient Non-Inverting Buck-Boost Converter with Improved Step Up/Down Ability

In this article, a new non-inverting buck-boost converter with superior characteristics in both bucking and boosting is presented. The proposed converter has some distinct features, such as high step-up/-down ability and low voltage/current stress on its switching devices. The voltage gain of the proposed converter is double the reported value for the traditional buck-boost converter. Although it has three switches, the three switches operate simultaneously, hence no dead-time is required. Two out of the three switches are under voltage stress equal to half of the output voltage. The overall efficiency of the system is promising because of the ability to select devices with low voltage drops. Converter analysis and steady-state performance in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) are presented in detail. A 1 kW hardware prototype of the converter was implemented in the laboratory; with a step-up ratio of 3.5 and 1 kW power, the measured efficiency is above 95.4%, and with step-up ratio 8, it is around 91.5%.
Development and Evaluation of Chinese Version Vision-related Quality of Life Questionnaire-25

Objective To develop and test a Chinese version vision-relatde quality of life questionnaire-25. Methods In this investigtion study, the National Eye Institute Visual Function Questionnaire (NEI VFQ-25) was translated and adapted into the Chinese version vision-related quality of life questionnaire (CVRQoL-25). The questionnaire items were completed by 113 patients with age-related cataract, hypermyopia, glaucoma, diabetic retinopathy and by a reference group (n=38). The rates of missing data, Cronbach' alpha coefficient, content validity, construct validity and discriminant validity of CVRQoL-25 were computed. The results were compared with patient demographics multivariate analysis of variance, factor analysis and Pearson correlation were used for statistical analysis. Results Based on the information from the participants, one item-"Driving" was changed to conclude driving cars and riding bicycles. At scale "Driving" , the rate of missing data was very high both in patient and control groups, while all the other scales were responded to each member in the research. Cronbach' alpha coefficient for the ten scales and the total CVRQoL-25 scale were above 0.6. There was significant difference between the two groups. The content validity of all scales were above 0.4 and each scale was included in one of the major factors. The scores of CVRQoL-25 were highly correlated with visual acuity of the better eye, both eye, and with education. Conclusion With minor modifications from the English version, CVRQoL-25 can be used as one measure instrument to evaluate the vision-related quality of life of patients with eye disease. The scores of CVRQoL-25 had no significant relations with sex, and had negtive relations with age. Subjects who with higher education degree had higher scores of CVRQoL-25. Key words: Vision; Quality of life; Questionnaire
Executive function and episodic memory composite scores in older adults: relations with sex, mood, and subjective sleep quality

ABSTRACT Executive function and episodic memory processes are particularly vulnerable to aging. We sought to learn the degree to which sex, mood, and subjective sleep quality might be related to executive function and episodic memory composite scores in community-dwelling older adults. We replicated Glisky and colleagues’ two-factor (i.e., executive function [N=263] versus episodic memory [N=151]) structure, and found that it did not significantly differ between males and females. Moderation analyses revealed no interactions between sex, mood, and sleep in predicting either composite score. However, females significantly outperformed males on the episodic memory composite, and on all the individual tests comprising it. Ours is the first study to look at sex differences in this battery’s factor structure and its potential relations with mood and sleep. Future longitudinal studies in both healthy and clinical populations will help us further probe the possible influence of these variables on executive function and episodic memory in aging.
Protective Abilities of an Inhaled DPI Formulation Based on Sodium Hyaluronate against Environmental Hazards Targeting the Upper Respiratory Tract

The exposure of lung epithelium to environmental hazards is linked to several chronic respiratory diseases. We assessed the ability of an inhaled dry powder (DPI) medical device product (PolmonYDEFENCE/DYFESATM, SOFAR SpA, Trezzano Rosa, Italy), using a formulation of sodium hyaluronate (Na-Hya) as the key ingredient as a defensive barrier to protect the upper respiratory tract. Specifically, it was evaluated if the presence of the barrier formed by sodium hyaluronate present on the cells, reducing direct contact of the urban dust (UD) with the surface of cells can protect them in an indirect manner by the inflammatory and oxidative process started in the presence of the UD. Cytotoxicity and the protection capability against the oxidative stress of the product were tested in vitro using Calu-3 cells exposure to UD as a trigger for oxidative stress. Inflammation and wound healing were assessed using an air-liquid interface (ALI) culture model of the Calu-3 cells. Deposition studies of the formulation were conducted using a modified Anderson cascade impactor (ACI) and the monodose PillHaler® dry powder inhaler (DPI) device, Na-Hya was detected and quantified using high-performance-liquid-chromatography (HPLC). Solubilised PolmonYDEFENCE/DYFESATM gives protection against oxidative stress in Calu-3 cells in the short term (2 h) without any cytotoxic effects. ALI culture experiments, testing the barrier-forming (non-solubilised) capabilities of PolmonYDEFENCE/DYFESATM, showed that the barrier layer reduced inflammation triggered by UD and the time for wound closure compared to Na-Hya alone. Deposition experiments using the ACI and the PillHaler® DPI device showed that the majority of the product was deposited in the upper part of the respiratory tract. Finally, the protective effect of the product was efficacious for up to 24 h without affecting mucus production. We demonstrated the potential of PolmonYDEFENCE/DYFESATM as a preventative barrier against UD, which may aid in protecting the upper respiratory tract against environmental hazards and help with chronic respiratory diseases.
Wireless resonant energy link for pulse generators implanted in the chest

This study investigates the feasibility of using the MedRadio band for wirelessly transmitting power to a rechargeable medical device implanted in the chest. In particular, a wireless energy link operating at 403 MHz and based on an inductive coupling between two planar resonators is considered, and its performance is assessed through simulations and experimental tests. Results show that a maximum value of the measured power transfer efficiency of ∼23% is achieved. Furthermore, the possibility of using the link for recharging a lithium-ion battery of a pulse generator implanted in the chest at a depth of 5 mm is discussed, and the compliance with safety regulations is verified. Reported results demonstrate that the proposed link can be used to charge a lithium-ion battery with a capacity up to 7.2 mAh, while inducing a peak of the specific absorption rate averaged over 1 g of tissue <1.6 W/kg.
Autonomous Minibus Service With Semi-on-Demand Routes in Grid Networks

This paper investigates the potential of autonomous minibuses which take on-demand directional routes for pick-up and drop-off in a grid network of wider area with low density, followed by fixed routes in areas with greater demand. Mathematical formulation for generalized costs demonstrates its benefits, with indicators proposed to select existing bus routes for conversion with the options of zonal express and parallel routes. Simulations on modeled scenarios and case studies with bus routes in Chicago show reductions in both passenger costs and generalized costs compared with existing fixed-route bus services between suburban areas and the central business district.
Pharmaceutical Supply Chain in China: Pricing and Production Decisions with Price-Sensitive and Uncertain Demand

In this paper, we apply game theory to study the price competition between drugstores and hospitals in China’s pharmaceutical supply chain. Motivated by drug shortages and price disparity problems, we build a simplified model with one supplier, one hospital, and one drugstore in which the sellers sell one kind of drug and compete on price. The hospital receives a discount from the government when ordering the drug and both sellers face a price-sensitive and uncertain demand. The existence and uniqueness of a Nash equilibrium are proved and closed-form solutions are found for linear demand cases. We characterize the pricing and ordering decisions of the hospital and drugstore. The analysis shows that high ex-factory price, high price sensitivity, and a small discount are three factors contributing to drug shortages. We consider two special kinds of linear demand to obtain insights into the drug price disparity problem.
