Published: August 2019

The need to maintain proper work life balance is becoming increasingly important; it has motivated several academic research efforts. In the quest for Lagos transformation from a mega city to a smart city, work life balance issues as it has to do with housing, work and urban liveability remains a contemporary issue that calls for keen attention. The rate of population increase in Lagos is not commensurate with the availability and development of social infrastructure, which has caused a number of the workers gainfully employed in Lagos to seek such in nearby state - Ogun State, specifically border towns which includes Ota, Ifo, Mowe, Magboro, Ibafo, Agbara etc. Consequently, such employees face job stress and work-life conflict caused by long working hours, unrelenting traffic, early resumption and late closure at work. This research examined the plausible consequence of work life imbalance measured by job stress and work-life conflict on the social life measured by job satisfaction and wellbeing of such people. A sample of 242 respondents was selected for survey using Yaro Yamane random sampling method & Rao Soft sample estimation method. Primary method of data collection was used. A well-structured questionnaire was administered and interviews were conducted while responses were analysed using product moment correlation and linear regression. Results proved that work life balance has profound impacts on the social life of workers in Lagos Metropolitan borders. This paper recommends that individuals should take active roles in ensuring work life balance; organisations must proactively identify and understand demographic & work related factors; create supportive workplace policies; adopt & implement flexible work strategies and assume the responsibility of reducing/eliminating job stress. In addition, Government should intervene and initiate measures to tackle transportation inadequacies with legislations on provision of work life balance incentives for workers.

Published: August 2019

Tuberculosis is an infectious disease affecting mostly lungs, that is still considered a health global problem as it causes millions of deaths worldwide. Current treatment is effective but associated with severe adverse effects due to the high doses of each anti-tuberculosis drug daily administrated by oral therapy. For the first time, a pyrazinoic acid (PA) biodegradable nanoconjugate was synthesized and developed for pulmonary administration in an attempt to reduce the administered doses by achieving a high drug payload and controlled release at the target site. The conjugate was synthesized by coupling pyrazinoic acid on carboxylic groups of poly(malic acid), which is a biodegradable and biocompatible polymer, and posteriorly self-assembled into nanoconjugates. Characterization confirmed the formation of nanometric, spherical and negatively charged pyrazinoic acid nanoconjugate (NC-PA). NC-PA was stable for 60 days at 4 and 37°C and able to deliver PA in a sustained release manner over time. On macrophages, they exhibited no cell toxicity for a wide range of concentrations (from 1 to 100 µg/mL), demonstrating the safety of NC-PA. In addition, the nanoconjugate was efficiently taken up by RAW 264.7 cells over 6 hours reaching a maximum value after 3 hours of incubation. In conclusion, innovative nanoconjugates are a promising alternative to deliver drugs directly to the lungs and contributing to improving tuberculosis therapy.

Authors: Heinz David , Saavedra Casilda
Published: August 2019

Anthropogenic activity has long been labeled as the leading cause of soil destabilization. However, natural factors including soil erosion and excess rainfall have also been some of the main causes of landslides. Panama is a country with a tropical climate and has a variety of soils that are susceptible to weakening by rainfall. Some contain a considerable amount of clay (Acrisols, Nitisols) while others do not (Andosols). Either kinds of soil are structurally weakened by large amounts of rain. The landslides produced by the destabilization of these soils have caused much damage in Panama. Chiriqui is a province that has seen an increase in landslides. This study, using historical meteorological and disaster data from 1985 until 2010, was focused on determining the relationship between the amount of average rainfall and the frequency of landslides in Chiriqui. The study found that Bugaba experienced the highest number of landslides during the study period and received considerable rainfall.

Authors: Setiyorini Tyas , Asmono Rizky Tri
Published: August 2019

Education is a very important problem in the development of a country. One way to reach the level of quality of education is to predict student academic performance. The method used is still using an ineffective way because evaluation is based solely on the educator's assessment of information on the progress of student learning. Information on the progress of student learning is not enough to form indicators in evaluating student performance and helping students and educators to make improvements in learning and teaching. K-Nearest Neighbor is an effective method for classifying student performance, but K-Nearest Neighbor has problems in terms of large vector dimensions. This study aims to predict the academic performance of students using the K-Nearest Neighbor algorithm with the Information Gain feature selection method to reduce vector dimensions. Several experiments were conducted to obtain an optimal architecture and produce accurate classifications. The results of 10 experiments with k values ​​(1 to 10) in the student performance dataset with the K-Nearest Neighbor method showed the largest average accuracy of 74.068 while the K-Nearest Neighbor and Information Gain methods obtained the highest average accuracy of 76.553. From the results of these tests it can be concluded that Information Gain can reduce vector dimensions, so that the application of K-Nearest Neighbor and Information Gain can improve the accuracy of the classification of student performance better than using the K-Nearest Neighbor method.

Construction of estimates of spectral densities with a given accuracy over intersecting intervals of observations
Authors: Semenchuk Natalia V.
Published: August 2019

The article proposes a new method for determining the number of splitting intervals and the number of observations in them when building estimates of the spectral densities of stationary random processes with a given accuracy over intersecting observation intervals based on asymptotic results, obtained for the first moment of convergence rate under the assumption that the spectral density satisfies the Lipschitz condition. Two cases are considered: with a single and arbitrary data taper. As a result, an algorithm is proposed for constructing estimates for intersecting intervals of observations with a given accuracy. This algorithm was tested on model examples for random AR(4) processes, using data taper of Riesz, Bochner, Parzen. The proposed method will be useful to the researcher in analyzing data in the form of stationary random processes using non­parametric methods of spectral analysis in an automated mode.
Elastic guide rail oscillation due to moving concentrated load
Authors: Savchuk Vladimir P. , Savenkov Pavel A.
Published: August 2019

This article illustrates the solution of a differential equation describing oscillations of an elastic tensioned guide rail, which consist of string bundle enclosed in an elastic cylindrical shell, while concentrated load, simulated by a material point, moves along it. The oscillatory system is considered in such way that the guide rail supports freely. The existing external and internal forces of resistance to movement of the guide rail are also taken into account. Initial and boundary conditions are zero. In article «A string bend under a moving load», published in the journal «Vestnik BGU. Seriya 1, Fizika. Matematika. Informatika» (2004, No. 1), the deflection of a flexible guide rail under load was obtained by solving an equation with deviating argument. In this article, an algorithm is constructed for finding deflection of an elastic tensioned guide rail in the form of a cubic splines. All the results of calculations are presented in a dimensionless form.

Published: August 2019

Objective: In recent years, cardiovascular disease (CVD) and CVD-related deaths have been increasing in the young population in Turkey. Nursing students should be informed about CVD and should reduce their own risk of this disease. This study was conducted to determine the impact of the knowledge of CVD risk factors among nursing students on the results of risk assessments.Methods: The population of study, which had a cross-sectional design, was composed of 587 students in nursing school at one university. The sample comprised 351 students who volunteered to take part in this study. The data were collected using the Cardiovascular Disease Risk Factors Knowledge Level (CARRF-KL) Scale, The Students’ CVD Risk Factors Information Form, a physician scale, a tape measure, a digital blood pressure monitor, a glucometer and cholesterol and triglyceride measuring devices.Results: The majority of the students (77.2%) were female, and the mean age was 20.77 years. The CARRF-KL Scale scores of the participants were low. In a significant majority of the sample, the anthropometric measurement results, blood pressure, respiration rate, pulse rate, blood glucose level, cholesterol level, and triglyceride level were within normal limits. As the knowledge level of CVD risk factors increased among the students, the blood glucose and cholesterol levels decreased.Conclusion: Although they were in the minority, some of the nursing students in the sample had an increased risk of CVD. Health screening programs should be performed more often at institutions that educate health professionals. Strategies for reducing the CVD risk in the risk students should be conducted, and these students should be monitored closely.

Published: August 2019

The consumption of food and its safety are important for human security. In this paper, we reviewed the literature on future possibilities for transforming the food system through digital solutions in the Barents region. Such digital solutions will make food business operators more efficient, sustainable, and transparent. Developing cross-border infrastructures for digitalization in the region will break the isolation of the local food system, thus simplifying the availability of processed, novel and safe traditional food products. It is necessary for food growers and processors to respond to the trends driven by consumers’ demand while ensuring their safety. Our review highlights the opportunities provided by digital technology to ensure safety and help food business operators predict consumer trends in the future. In addition, digitalization can create conditions that are necessary for the diversification of organizational schemes and the effective monitoring of food processing operations that will help to promote food and nutrition security in the Barents region.

Although compost and biochar received high attention as growing media, little information is available on the potential of vineyard by-products for the production and use of composted solid digestate (CSD) and biochar (BC). In the present study, two experiments are reported on CSD and BC mixed with commercial peat (CP) for grapevine planting material production. Four doses (0, 10%, 20%, 40% vol.) of CSD and BC were assessed in the first and second experiment, respectively. CSD mixed at a dose of 10% recorded the highest values of shoot dry weight (SDW) and a fraction of total dry biomass allocated to shoot (FTS), both cropping bench-graft and bare-rooted vine. On the other hand, CSD mixed at a dose of 40% displayed the highest values of SDW and FTS, cropping two-year-old vine. BC used at a dose of 10% improved SDW, root dry weight, total dry weight, FTS, shoot diameter, and height on bare-rooted vine. The present study shows that CSD and BC, coming from the valorization of vineyard by-products, can be used in the production of innovative growing media suitable for nursery grapevine production. Further studies are needed to assess the combined applications of CSD and BC in the same growing media.

Decreased ability to control posture is correlated with the risk of falls among older individuals. In particular, reactive postural control ability response to even small perturbations is important for fall prevention of older individuals. The current study sought to design a new wearable assistive device for improving balance function by generating small perturbations using pneumatic gel muscle (PGM). Furthermore, we investigated the effects of using the proposed device for balance training. The proposed wearable balance exercise device utilized PGMs possessing various features, such as a lightweight design and the ability to generate small perturbations with a small power source. We investigated the effects of the device on reactive postural control exercises. Seven healthy participants participated in this study. Three-dimensional acceleration data (Ax, Ay, and Az) were measured from participants during a single leg stance in each session. The peak Ax value generated by perturbations and responses significantly differed from baseline peak acceleration. The peak Ay value caused by perturbations was significantly decreased compared with baseline peak acceleration. In addition, the root mean square Ax value of the post-test significantly decreased compared with the pre-test value. Our results revealed that the proposed wearable balance exercise device was able to create small perturbations for assessing reactive postural balance control. Furthermore, the device was able to improve users’ stability.

The current success rate of CubeSat missions, particularly for first-time developers, may discourage non-profit organizations to start new projects. CubeSat development teams may not be able to dedicate the resources that are necessary to maintain Quality Assurance as it is performed for the reliable conventional satellite projects. This paper discusses the structured life-cycle of a CubeSat project, using as a reference the authors’ recent experience of developing and operating a 2U CubeSat, called qbee50-LTU-OC, as part of the QB50 mission. This paper also provides a critique of some of the current poor practices and methodologies while carrying out CubeSat projects.
Research on the Damage Evolution Process of Steel Wire with Pre-Corroded Defects in Cable-Stayed Bridges
Authors: Wang Ying , Zheng Yuqian
Published: August 2019

A numerical simulation method is presented in this paper to study the damage evolution and failure process of high-strength steel wires with pre-corrosion defects in cable-stayed bridges under fatigue loads. This method was based on the mechanism of crack nucleation accelerated by corrosion pits, in which cellular automata (CA) and finite element (FE) simulation methods were used. First, based on the continuum damage mechanics (CDM) theory, a fatigue damage model suitable for steel wire with pre-corroded defects was established to describe the evolution process of the microscopic damage of steel wires, and a user-defined material subroutine (UMAT) was written using formula translator (FORTRAN) language. Then, in MATLAB, the shape and position of random pitting defects on the steel wire surface were generated using 3D CA technology. Afterwards, a pitting defect model was successively inputted into AutoCAD, Rhino and ABAQUS software to obtain the FE model of steel wire with initial pitting defects or initial damage. Finally, the life-and-death element method and the UMAT program were used to simulate the fatigue damage evolution process of the steel wire with initial defects in ABAQUS software, and the fatigue life of the steel wire was obtained. The results show that the proposed strategy and algorithm can effectively describe the fatigue damage evolution process of the steel wire with initial pitting defects under the action of a fatigue load, and the simulated fatigue life is in good agreement with the experimental results. The obtained stress-life (S-N) curves of the steel wire with different corrosion degrees show that the influence of pit corrosion on fatigue life is much greater than that of the mass loss caused by corrosion. By comparing the irregular pit model with regular pit models, it can be found that the irregular shape angle is the main reason for the smaller fatigue life and the larger stress concentration in the irregular pit model than in the regular pit model.

The aim of the study was to analyze the relationship between the angle of spinal curvature and surface electromyography (SEMG) amplitude of the erector spinae in young school-children. A total of 251 children aged 7–8 participated in the study. The analysis involved 103 (41%) children with scoliosis, 141 (56.17%) with scoliotic posture, and seven (3.0%) with normal posture. Body posture was evaluated using the Diers formetric III 4D optoelectronic method. Analysis of SEMG amplitude of the erector spinae was performed with the Noraxon TeleMyo DTS apparatus. A significant correlation was found between the angle of spinal curvature and the SEMG amplitude of the erector spinae. The most important and statistically significant predictor of the SEMG amplitude and scoliosis angle in the scoliosis group was the standing position, chest segment, right side. The largest generalized SEMG amplitude of the erector spinae occurred in both boys and girls with scoliosis. Impaired balance of muscle tension in the erector spinae can trigger a set of changes that create a clinical and anatomopathological image of spinal curvature.

The increased industrial application potentials of peroxidase have led to high market demand, which has outweighed the commercially available peroxidases. Hence, the need for alternative and efficient peroxidase-producers is imperative. This study reported the process parameters for enhanced exoperoxidase production by Ensifer adhaerens NWODO-2 (accession number: KX640918) for the first time, and characterized the enzyme using molecular methods. Peroxidase production by the bacteria was optimal at 48 h, with specific productivity of 12.76 U mg−1 at pH 7, 30 °C and 100 rpm in an alkali lignin fermentation medium supplemented with guaiacol as the most effective inducer and ammonium sulphate as the best inorganic nitrogen source. Upon assessment of some agricultural residues as sources of carbon for the enzyme production, sawdust gave the highest peroxidase productivity (37.50 U mg−1) under solid-state fermentation. A search of the polymerase chain reaction (PCR)-amplified peroxidase gene in UniProtKB using blastx showed 70.5% similarity to an uncharacterized protein in Ensifer adhaerens but phylogenetic analysis suggests that the gene may encode a catalase-peroxidase with an estimated molecular weight of approximately 31 kDa and isoelectric point of about 11. The nucleotide sequence of the detected gene was deposited in the GenBank under the accession number MF374336. In conclusion, the ability of the strain to utilize lignocellulosic materials for peroxidase production augurs well for biotechnological application as this would greatly reduce cost, which is a major challenge in industrial enzyme production.

Published: August 2019

Automated tongue segmentation is a critical component of tongue diagnosis, especially in Traditional Chinese Medicine (TCM), where it has been practiced for thousands of years and is generally considered pain-free and non-invasive. Therefore, a more precise, fast, and robust tongue segmentation system to automatically segment tongue images from its raw format is necessary. Previous algorithms segmented the tongue in different ways, where the results are either inaccurate or time-consuming. Furthermore, none of them developed a dedicated, automatic segmentation system. In this paper, we proposed TongueNet, which is a precise and fast automatic tongue segmentation system. U-net is utilized as the segmentation backbone applying a small-scale image dataset. Besides this, a morphological layer is proposed in the latter stages of the architecture. The proposed system when applied to a tongue image dataset with 1000 images, achieved the highest Pixel Accuracy of 98.45% and consumed 0.267 s per picture on average, which outperformed conventional state-of-the-art tongue segmentation methods in both accuracy and speed. Extensive qualitative and quantitative experiments showed the robustness of the proposed system concerning different positions, poses, and shapes. The results indicate a promising step in achieving a fully automated tongue diagnosis system.
