Published: June 2022

For a future hydrogen economy, non precious metal catalysts for the water splitting reactions are needed that can be implemented on a global scale. MNC catalysts with MN4 active sites show promising performance, but an optimization rooted in structure property relationships has been hampered by their low structural definition. Porphyrin model complexes are studied to transfer insights from well-defined molecules to MNC systems. This work combines experiment and theory to evaluate the influence of porphin substituents on the electronic and electrocatalytic properties of MN4 centers with respect to the hydrogen evolution reaction (HER) in aqueous electrolyte. We found that the choice of substituent affects their utilization on the carbon support and their electrocatalytic performance. We propose an HER mechanism for supported iron porphyrin complexes involving a [FeII(P▪)]- radical anion intermediate, in which a porphinic nitrogen atom acts as an internal base. While this work focuses on the HER, the limited influence of a simultaneous interaction with the support and an aqueous electrolyte will likely be transferrable to other catalytic applications.

Review of training-free event-related potential classification approaches in the World Robot Contest 2021
Authors: Wu Huanyu , Wu Dongrui
Published: June 2022

Recently, rapid serial visual presentation (RSVP), as a new event- related potential (ERP) paradigm, has become one of the most popular forms in electroencephalogram signal processing technologies. Several improvement approaches have been proposed to improve the performance of RSVP analysis. In brain–computer interface systems based on RSVP, the family of approaches that do not depend on training specific parameters is essential. The participating teams proposed several effective training-free frameworks of algorithms in the ERP competition of the BCI Controlled Robot Contest in World Robot Contest 2021. This paper discusses the effectiveness of various approaches in improving the performance of the system without requiring training and suggests how to apply these approaches in a practical system. First, appropriate preprocessing techniques will greatly improve the results. Then, the non-deep learning algorithm may be more stable than the deep learning approach. Furthermore, ensemble learning can make the model more stable and robust.

Published: June 2022

Electroencephalogram (EEG) data depict various emotional states and reflect brain activity. There has been increasing interest in EEG emotion recognition in brain–computer interface systems (BCIs). In the World Robot Contest (WRC), the BCI Controlled Robot Contest successfully staged an emotion recognition technology competition. Three types of emotions (happy, sad, and neutral) are modeled using EEG signals. In this study, 5 methods employed by different teams are compared. The results reveal that classical machine learning approaches and deep learning methods perform similarly in offline recognition, whereas deep learning methods perform better in online cross-subject decoding.
Modified PSO Based Channel Allocation Scheme for Interference Management in 5G Wireless Mesh Networks
Authors: Benni Nirmalkumar S. , Manvi Sunilkumar S.
Published: June 2022

Efficient channel management is a challenge that next-generation wireless networks need to meet in order to satisfy increasing bandwidth demand and transmission rate requirements. Non-orthogonal multiple access (NOMA) is one of such efficient channel allocation methods used in 5G backhaul wireless mesh networks. In this paper, we propose a power demand-based channel allocation method for 5G backhaul wireless mesh networks by employing NOMA and considering traffic demands in small cells, thereby improving channel utility. In this scheme, we work with physical layer transmission. The foremost aim is to mutually optimize the uplink/downlink NOMA channel assignment in order to increase user fairness. The approach concerned may be divided into two steps. First, initial channel allocation is performed by employing the traveling salesman problem (TSP), due to its similarity to many-to-many double-side user-channel allocation. Second, the modified particle swarm optimization (PSO) method is applied for allocation updates, by introducing a decreasing coefficient which may have the form of a standard stochastic estimate algorithm. To enhance exploration capacity of modified the PSO, a random velocity is included to optimize the convergence rate and exploration behavior. The performance of the designed scheme is estimated through simulation, taking into account such parameters as through put, spectral efficiency, sum-rate, outage probability, signal to-interference plus noise ratio (SINR), and fairness. The proposed scheme maximizes network capacity and improves fairness between the individual stations. Experimental results show that the proposed technique performs better than existing solutions.
Telecom Operator’s Approach to QoE
Authors: Kowalik Karol , Andruloniw Paweł , Partyka Bartosz , Zwierzykowski Piotr
Published: June 2022

Telecommunication networks are ever more frequently relying on artificial intelligence and machine learning techniques to detect specific use patterns or potential errors and to take automated decisions when these are encountered. This concept requires that methods be employed to measure the level of quality of a given telecommunication service, i.e. to verify quality of service (QoS) metrics. In a broader context, methods assessing the entire user experience (quality of experience – QoE) are required as well. In this article, various approaches to assessing QoS, QoE and the related metrics are presented, with a view to implement these at an FTTH network operator in Poland. Since this article presents the architecture of the system used to analyze QoE performance based on a number of QoS metrics collected by the operator, we also provide a comprehensive introduction to the QoS and QoE metrics used herein.
RED-LE: A Revised Algorithm for Active Queue Management
Authors: Hassan Samuel O.
Published: June 2022

The random early detection (RED) algorithm was developed in 1993. Nearly three decades later, several improved variants have been proposed by scientists. The use of a (pure) linear function for computing packet drop probability has turned out to be a disadvantage, leading to the problem of large delays. Such a problem may be addressed by using linear and non-linear (i.e. as exponential) packet drop probability functions. This paper proposes a revised RED active queue management algorithm named RED-linear exponential (RED-LE). This variant involves an interplay of linear and exponential drop functions, in order to improve the performance of the original RED algorithm. More importantly, at low and moderate network traffic loads, the RED-LE algorithm employs the linear drop action. However, for high traffic loads, RED-LE employs the exponential function for computing the packet drop probability rate. Experimental results have shown that RED-LE effectively controls congestion and offers an improved network performance under different traffic loads.

Authors: Kong Xiangqiang
Published: June 2022

In this paper, based on the concept of dual generalized quaternions, the study of dual generalized quaternions is transformed into a study of the matrix representation of dual generalized quaternions. With the aid of a polar representation for dual generalized quaternions, De Moivre’s theorem is obtained for the matrix representation of dual generalized quaternions, and Euler’s formula is extended. The relations between the powers of matrices associated with dual generalized quaternions are determined, and the n-th root of the matrix representation equation of dual generalized quaternions is found.

Authors: Rusli Herman , Safhida Maya , Erdiana Nira , Wildan Wildan
Published: June 2022

This article is a study of the thoughts of Indonesian female writers towards Acehnese women as reflected in the literary works they produce. The objects used are the novel Perempuan Keumala by Endang Moerdopo (2008) and the novel Seulusoh by D. Kemalawati (2006). These two manuscripts were chosen because the background story used is about Aceh, the characters in the novel are Acehnese women. So far, it is difficult to find female Indonesian writers who highlight the social life of the female Acehnese in their stories. Thus, this study can be used as the basis for literary criticism in the field of Acehnese gynocritic feminism. This study uses a qualitative approach with descriptive text analysis. The theory that is used as the rationale for this study is Showalter's gynocritic literary criticism (1981 and 2000), which is now as a theory of contemporary literary criticism. The results of the analysis reflect the thoughts of Acehnese women writers on the figures of Acehnese women and Acehnese women in the view of women authors outside Aceh. The focus of the analysis includes (1) female biological elements; (2) female psychological elements; (3) female language; and (4) female culture. The results of the study show that Acehnese women in Acehnese women's literary works tend to appear as feminine figures, but are also brave, responsible, and have high social sensitivity. As for Acehnese women, in the eyes of women outside Aceh, they are described as brave, hard, responsible, and have a heroic spirit.

Authors: N. E. Fouda Mohammed , Almaged Ahlam
Published: June 2022

The main purpose of Airbags installed in automotives is to protect drivers as well as accompanying passengers during an accident. Despite their safety benefits, a considerable number of airbag-associated injuries are reported in the literature. Airbags are designed to open in head-on collisions when vehicle deceleration exceeds a specified threshold. Defective airbags deployment with metal projectiles launching and hitting passenger’s head or neck have been reported.
Deaths from defective airbags are rarely reported in the Middle East. This article presents a case in the Kingdom of Bahrain of a driver whose car was in a head-on collision with another car resulting in in severe head trauma and death at the scene. Death scene investigation revealed that a fire has originated from the airbag compartment with a cylindrical metallic object found missing a part of it. Autopsy of the deceased showed an injury to the right side of the head similar to a firearm inlet. Examination of the head revealed a cylindrical metal object that did not resemble firearm projectiles. The object appeared to have come from the interior of the car upon impact. Laboratory analysis confirmed that the two metallic objects recovered from the deceased’s body were actually the broken pieces of airbag compartment. each other.
Although airbags have greatly reduced morbidity and mortality in road traffic accidents, defective airbags highlight the need to increase awareness of their hazards and the importance of their regular inspection and replacement if found defective

Authors: Oghenemavwe Loveday Ese , D. Orupabo Clinton
Published: June 2022

Estimation of the sex of unknown skeletal remains is a daunting challenge, when only fragmented bones are available. For this reason, there is a need to study population specific histomorphometric features of bones to provide useful data for the process of identification. The purpose of this study was to estimate sex from six histomorphometric parameters of cortical bones in a cohort of Nigerian patients.
The samples comprised non-pathologic bones collected from 29 patients (12 females and 17 males) between the ages of 35 to 85 years during orthopaedic procedures. The modified Frost’s manual method was used to prepare the histological sections of the cortical bones. The parameters evaluated were number of primary osteons (Os-p), number of secondary osteons (Os-s), osteon fragments (Os-f), non-Haversian canal (N-Hc), area of Haversian canal (Area Hc), and Haversian canal diameter (HCD). The data obtained were analyzed using SPSS version 23.0. Tests for sex differences were done using student t-test and stepwise discriminant function was used to formulate a predictive model for sex estimation.
The mean Os-p, Os-s, Os-f, N-hc, Area HC, and HCD were 2.85 ± 0.86,3.92 ± 1.26,6.08 ± 1.37, 2.23 ± 0.66, 53.43 ± 5.55, and 7.85 ± 0.41 for males and 1.11 ± 0.56, 0.33 ± 0.17, 2.44 ± 0.67, 54.37 ± 6.04 and 7.426 ± 0.35 for females, respectively. The mean value of Os-s was significantly different in males and females (p=0.04). Stepwise discriminant function analysis showed Os-s could be used to estimate sex. 71.4% of our samples were correctly predicted based on sex. Discriminant function values of 0.418 and -0.626 were predictive values for males and females, respectively, using the DFA predictive model.
Our study shows that the number of secondary osteons (Os-s) could be used to estimate sex in Nigerian patients.

Authors: Byukusenge Céline , Nsanganwimana Florien , Tarmo Albert Paulo
Published: June 2022

Scholars have debated whether virtual laboratories are educationally effective tools and if they should be continuously developed. In this paper, we comprehensively review literature about the effectiveness of virtual labs in teaching and learning biology to identify the topics often taught and the linked learning outcomes. We used Google Scholar, ERIC, and Web of Science electronic databases to access journal articles and conference proceeding papers. Through a systematic analysis, we obtained 26 articles solely related to virtual lab use in biology education. The overall findings from the reviewed literature indicated that virtual laboratories are often used on topics that seem abstract. These include cell and molecular biology topics, followed by microbiology, genetics, and other practical topics such as dissection and biotechnology. This review study revealed that virtual labs are effective as they improve students’ conceptual understanding, laboratory or practical skills, and motivation and attitudes towards biology. We recommend the use of virtual labs in teaching as a means of actively involving students in safer and more cost-effective scientific inquiry.
Exploring the Teacher Professional Development Activities: Perspectives of Nigerian High School Teachers
Authors: Ajani Oluwatoyin Ayodele
Published: June 2022

The quality of education is central to the Sustainable National Development that can be attained by any country. Hence, the professional development of teachers is critical to classroom practices in the education system. Teachers attend various professional development activities every year to improve their classroom practices. The aim of the study was to establish teachers’ perspectives on professional development activities. The study adopted an interpretive qualitative approach to explore teachers' views on the phenomenon. The study engaged three heads of departments in semi-structured interviews and five teachers in a focus group interview to explore teachers’ lived experiences of professional development. The study employed andragogy as the theoretical framework to understand teachers' views on workshops, subject association meetings, conferences and other professional development activities they attended. Thematic analysis of the data was carried out systematically to generate themes from the findings. Teachers did not regularly attend annual professional development activities. The contents of the professional development activities did not adequately address teachers’ needs for dynamics in the classroom. It is therefore recommended that teachers’ classroom practices be assessed by their heads of departments, vice principals/principals or subject specialists to determine how their classroom practices could be enhanced. The frequency of professional development activities for teachers should be increased every year, to improve their classroom practices.

Assessment of disease activity with simplified joint ultrasonography method in rheumatoid arthritis patients
Authors: Orucoglu Nurdan , Alp Alev , Yurtkuran Deniz Merih
Published: June 2022

Background/Aim: Ultrasound (US) is a highly useful tool for assessing the disease activity of rheumatoid arthritis (RA). On the other hand, examining all joints could be time-consuming and unfeasible. Defining the number of joints and which joints should be tested is essential to accurately measuring RA activity. Several simplified US methods are undergoing development for this purpose. The aim of this study was to assess the correlation between simplified 12-joint US findings and physical examination findings/disease activity in RA patients.

Methods: This cohort study included 62 RA patients who had been undergoing treatment for at least three months. Multiplanar grayscale images and power Doppler (PD) of the 12 joints (bilateral elbow, wrist, second and third metacarpophalangeal [MCP] joints, knee, and ankle) were acquired and compared with clinical assessments. Disease activity was assessed using the clinical disease activity and simplified disease activity indices and disease activity score-28 (CDAI, SDAI, and DAS28, respectively). Synovial effusion, synovial proliferation, and PD US scores were calculated for 12 joints. Correlations between US scores and disease activity, clinical examination, and acute phase reactants were assessed.

Results: The number of joints with PD activity and US total and US synovial proliferation scores showed weak correlations with clinical activity scores (r = 0.25, r = 0.26, and r = 0.28 for SDAI and r = 0.23, r = 0.26, and r = 0.28 for DAS28, respectively). The CDAI did not present any statistically significant correlations. The agreement between US findings and clinical joint examination was generally weak. PD activities of the second MCP joints (r = 0.84, P < 0.01) and knees (r = 0.42, P < 0.01) mostly correlated with clinical examination although it was weakly correlated at the third MCP (r = 0.152) and wrist (r = 0.148), and not correlated at the elbow (r = 0.125).

Conclusion: The weak correlation between US findings and clinical examination/disease activity suggests that clinical examination alone may not be sufficient to determine joint inflammation and disease activity. US could provide a more accurate assessment of RA patients and aid in medication selection.

Authors: Türkmen Ayşe Sonay , Şahiner Nejla Canbulat , Ateş Beşirik Selda , Uysal Mehmet
Published: June 2022

Background/Aim: Circumcision is an invasive operation that male children undergo in our country and some others. During this process, the child can experience fear, anxiety, and pain simultaneously. As a randomized controlled VR study, this research was conducted to determine the effect of virtual reality (VR) glasses on reducing fear/anxiety and pain during circumcision in children.

Methods: The study was conducted on 125 children (6-11 years old). The same healthcare team performed the circumcision of the children in both groups. The children were randomly split into VR and control groups. The children in the VR group, just before the circumcision, watched their preferred cartoon film via VR glasses. No additional procedure was applied to the children in the control group except for ordinary procedures in the hospital. The fear and pain status measured by Wong-Baker Faces Pain Rating Scale and Children Fair Scale of all the children were evaluated before and after the operation by the child, parents, and the observer. Descriptive statistics, chi-square, and t-tests analyzed the data.

Results: There was no significant difference between the groups regarding demographic characteristics such as age, BMI, previous hospitalization, and anesthetic drug used before the procedure of the children included in the study. Preoperative (VR = 1.03 (0.18), control = 1.05 (0.22)) and pre-procedural (VR = 2.61 (1.02), control = 2.33 (1.22)) fear levels were also similar (P > 0.05). After the procedure, it was determined that the mean duration of the procedure (365.36 (64.73) sec), crying time (21.31 (41.74) sec), and fear scores (0.36 (0.68)) of the children in the VR group were lower (P < 0.001). However, pain mean scores were similar (P > 0.05).

Conclusion: It is thought that watching a cartoon with VR glasses during the circumcision operation may be effective in reducing the child's fear level, crying, and operation time.

Published: June 2022

International tourists’ perceptions of the destination’s image, travel satisfaction and revisit intentions are crucial to effective destination marketing and overall destination competitiveness. Tourist destinations often compete through their image in potential tourists’ minds. Therefore, a destination image is central due to its influence on tourists’ decision-making and destination selection. Successful destination marketing depends on the in-depth understanding of the destination image held by tourists. This study investigates the destination image changes of Mongolia for specific periods of time. The research examines the attributes of destination images through a longitudinal comparison of data sets from 2004 to 2019 to determine if any change in destination images existed over time. The research model was developed on the attributes of cognitive and affective images, tourist satisfaction, and revisit intentions. The first set of data was obtained from the 280 international tourists who travelled to Mongolia in 2004. The second set of data was obtained from 310 international tourists who travelled to Mongolia in 2019. The research model was validated using structural equation modelling. Independent sample t-tests were performed using two data sets to examine changes in the destination image over the years. The result shows that there are positive changes in the cognitive and affective image of the destination in a given period of time, which influenced tourist satisfaction and their revisit intentions. The implications of the research findings for the travel intermediaries, destination marketing organizations, and potential future research are also discussed.

Cynthia Ozick is an emphatic voice of new Jewish American novels who reveals various issues that a Jew has to face while living in a mainstream American culture. She advocates ethnicity and chooses the comic mode to reveal the truth. The present paper aims at the in-depth study of the second collection of short stories "Bloodshed and three Novellas'. In these stories Ozick which focuses on the betrayal of tradition by Jews. She brings out the hilarious situations and ideas by focusing on various flaws and blemishes in the personalities of her characters. She also mocks at their defective physical appearances. In fact the comic elements in her fiction have a much higher purpose than only evoking laughter. The present paper also attempts to study how Ozick's comedy is a mirror of human reality and focuses on humanity. The present paper is an endeavour to show how Ozick's comedy has a fair share of flippancy, folly and jest and how it manifests itself in forms like irony, satire, grotesque and farce.

Empty fruit bunch (EFB) is one of the abundant biomass waste from oil palm and it is an issue that it can be used as renewable energy in the form of Bio-oil. Bio-oil is produced by a thermal cracking process. This research aims to identify the potential environmental impact of Bio-oil production from EFB as fuel. Life Cycle Assessment (LCA) with gate to gate approach is used in data processing applications for networks in Simapro V.9 and the database used is similar to the characteristics of the eco invent database. Functional units are used to show environmental references in impact categories, such as energy used and global warming potency. The results show that the stage of the bio-oil production cycle in the pretreatment process has a greater global warming impact than the others, amounting to 131.10013 kg CO2 eq. The results of the analysis using the networking graph on the Simapri, show that the environmental hotspot of the thermal cracking process for Bio-oil production is caused by the use of electricity from the State Electricity Company (PLN) and the release of chemical substances from the process. From the results of the LCA, environmental performance improvement or continuous improvement can be done is by managing energy use and installing equipment.

Vannamei shrimp entered Indonesia to replace tiger prawns (Penaeus monodon), which then experienced disease attacks and decreased quality. However, with various advantages, the cultivation of vaname shrimp still has problems during the cultivation period. Therefore, this study will determine the effect of adding white turmeric extract (Curcuma zedoaria) on the immune system of vannamei shrimp (Litopenaeus vannamei). This research was carried out for 60 days using experimental research methods, and the research design used was a completely randomized design (CRD) consisting of 4 treatments with 3 replications were P1: Artificial feed infection, P2: Artificial feed +0, 5% white turmeric extract, P3: Artificial Feed+1% white turmeric extract, P4: Artificial Feed+2% white turmeric extract. The results showed that administration of white turmeric extract (Curcuma zedoaria) with a dose of 1% gave the best results and natural effect on the survival rate of 83.3%, Total Haemocyte Count of 1.4x107 cells/mL, and Differential Haemocyte Count (hyaline cells). In addition, by 23%, semi-granulocytes by 18.3%, and granulocytes by 58.7%, which play a role in the immune system of white vaname shrimp. In addition, the value of phagocytic activity was 68.8%.

Coffee production in Sidomulyo Village, located at the foot of Mount Gumitir, Silo District, Jember Regency, is famous for being very abundant. This condition is very supportive of the increasing needs of coffee drink lovers. However, the taste of ready-to-brewed ground coffee produced by the Sidomulyo Koperasi WANITA is still unable to compete with coffee on the market. This activity aimed to provide training on civet coffee production through the dry coffee bean fermentation method as a primary ingredient. The fermentation process was carried out using a Magnetic Fermentation machine which was the result of research in 2020. The fermentation process training activity was attended by 15 members of the Koperasi WANITA. 50 kg of dry coffee was fermented using a Magnetic Fermenter machine. Dry coffee was soaked first in warm water (temperature around 30 - 400C) for 5 hours. Then it was drained and put in a fermenter box by adjusting the intensity of the ELF magnetic field to around 300 T for 90 minutes. The coffee beans were transferred to buckets and ripened for up to 5 days, then washed and sun-dried for three days, after drying in Roasting and continue grinding. The targeted outputs of this activity included scientific publications in the National Journal of Abdimas with ISSN. The results of this activity had produced fermented coffee beans that had been roasted in the form of roasted coffee beans and ground coffee. Based on the results of the evaluation, the members of the Ketakasi Koperasi already had skills in producing artificial Luwak coffee. This had the potential to develop superior products for Sidomulyo civet coffee.

Authors: Hani Tri Muhammad
Published: June 2022

The Circular Letter of the Minister of Health Number 303 of 2020 concerning the Implementation of Health Services through the Use of Information and Communication Technology in the Context of Preventing the Spread of Covid-19 has created a new norm that is contrary to the Regulation of the Minister of Health Number 20 of 2019 concerning Telemedicine Services between Health Service Facilities. The purpose of this research is to study the position of the circular letter legally-formally and also to examine the material substance of the circular letter through comparison with several related regulations. The research method used is normative juridical by researching legal principles, legal systematics, level of legal synchronization, legal history, and legal comparison. The result of this research indicates that the position of the circular in the positive legal system in Indonesia is not a regulation (regeling) or a state administrative decision (beschikking). There was disharmony of regulations between this Circular of the Minister of Health and several related laws and regulations above. Disharmony occurs because this circular has become a new norm that contradicts the Regulation of the Minister of Health as well as the Regulation of the Indonesian Medical Council which regulates telemedicine services between health facilities. Conflicts also occur with the law on medical practice, health law, the law on information and electronic transactions, .and the Civil Code
