Published: October 2022

Com o aumento significativo de usuários móveis, a busca pelo gerenciamento de recursos tornou-se essencial. Essa gerência deve visar atender à cobertura do sinal, mas, principalmente, manter o Acordo de Nível de Serviço desejado, independentemente do número de usuários conectados. Assim, propomos a utilização de quatro modelos de predição aplicado ao número de usuários conectados em uma rede sem fio. A partir dessas previsões, os recursos de rede podem ser alocados adequadamente. Investigamos o uso de Otimização de Enxame de Partículas e Algoritmo Genético para hiperparametrizar um Perceptron Multicamadas e uma Árvore de Decisão. Avaliamos nossa proposta utilizando dados reais de rede sem fio com mais de 20 mil usuários. Como resultado, obtivemos uma precisão média de 94,80%, melhorando consideravelmente a utilização de recursos da rede e atendendo um nível de acordo de serviço de 95%.

Authors: Silva Fernando D. M. , Cruz Pedro , Costa Luís Henrique M. K.
Published: October 2022

Em cidades inteligentes, aplicações de monitoramento de frotas veiculares encontram problemas de classificação de trajetórias, devido a problemas variados como limitações dos dispositivos e falhas de comunicação ou de configuração. Uma solução frequentemente usada é a classificação em nuvem dos dados de trajetória coletados, feita com o uso algoritmos de similaridade de trajetórias. Porém, algoritmos como o Dynamic Time Warping (DTW) e o Longest Common Subsequence (LCSS) podem se tornar custosos em cenários com grande volumes de dados. Assim, neste artigo é proposto o Unordered and Vectorized Common Segment Ratio Classifier (UV-CSRC), que propõe classificar segmentos de trajetórias com o uso de aceleração de hardware. Através de testes com dados reais e sintéticos demonstra-se que o algoritmo, em cenários reais, obtém uma acurácia semelhante ao do DTW e do LCSS, com tempo de processamento ao menos 28 vezes mais rápido.

Rumo à Concepção de Diretrizes para Design da Gamificação sob a ótica da IHC feminista
Authors: Cordova Karine Alessandra , Klock Ana Carolina Tomé , Gasparini Isabela
Published: October 2022

A gamificação é uso de elementos de jogos em contextos não lúdicos visando engajar um público específico e motivar comportamentos. Ao considerar a diversidade do desenvolvimento de soluções tecnológicas, percebe-se que a grande maioria das pessoas que se desenvolvem na área de gamificação são homens, o que torna a gamificação um objeto de estudo interessante. Assim, este trabalho visa estabelecer um conjunto de diretrizes para auxiliar o design da gamificação sob a perspectiva da IHC feminista. Como resultado, espera-se que as soluções tenham maior diversidade criativa e que as pessoas se sintam mais incluídas no processo.

Published: October 2022

Um dos principais eventos que envolve a economia mundial em 2022 é o conflito entre Rússia e Ucrânia. Esse evento oferece uma oportunidade ímpar para analisar como acontecimentos dessa magnitude podem refletir no uso de criptomoedas. Este trabalho busca investigar o comportamento de contas e suas transações na rede de criptoativos Ethereum durante esse evento. Para tal fim, coletamos todas as transações realizadas duas semanas antes e duas semanas após o início do conflito, organizadas em dois grupos: o conjunto das contas envolvidas nessas transações e o subconjunto dessas contas que interagiram com um serviço dentro do Ethereum, chamado Flashbots Auction. Então, modelamos grafos temporais em que cada vértice representa uma conta e cada aresta representa uma transação realizada entre duas contas. Analisamos o comportamento dessas contas via métricas de grafos para ambos os grupos durante cada semana observada. Os resultados mostram mudanças no comportamento e atividade de contas, bem como variações no volume diário de transações.
Sobre-aprovisionamento de capacidade baseado no modelo de tráfego de Erlang
Authors: Waldman Helio , Bortoletto Rodrigo Campos , Troyano Michel Scassiotte
Published: October 2022

Durante o século passado, o modelo de Erlang foi amplamente aceito para representar a dinâmica de alocação de recursos (canais) em redes de comutação. Entretanto, ele é um modelo assintótico, cuja validade pressupõe um número infinito de fontes, cada uma das quais produzindo uma quantidade infinitesimal de tráfego. Embora essa condição fosse bem aproximada nas antigas redes públicas de telefonia, ela é questionável nas modernas redes ópticas que constituem a espinha dorsal da infraestrutura da Internet. Esse artigo procura quantificar o erro causado pelo uso do modelo de Erlang no dimensionamento de um enlace avulso. Para isso, ele usa como referência o modelo de Engset, que é baseado num número finito de fontes, cada uma com tráfego finito, sendo assim mais realista, ainda que mais complexo. O artigo discute a necessidade de usar fórmulas recursivas encontradas na literatura para expressar as probabilidades de bloqueio, e coloca essa fórmulas em função do tráfego oferecido nos dois modelos para propiciar a comparação entre os dimensionamentos preconizados. É então constatada e avaliada a existência do sobredimensionamento causado pela adoção do modelo de Erlang em função do número de fontes.
Virtual Resource Allocation for URLLC in MEC-enabled UAVs: A Reliability and Availability Analysis
Authors: Falcão Marcos , Souza Caio , Balieiro Andson , Dias Kelvin
Published: October 2022

Unmanned Aerial Vehicle (UAV) communication networks and Multiaccess Edge Computing (MEC) will occupy an important position in the future wireless communication system. Unlike regular datacenter environments, MEC can help mobile devices improve computing and communication capabilities, and its combination with UAVs helps to deal with the Line of Sight (LoS) issues, besides allowing node mobility. This work addresses the dynamic resource provisioning in a UAV equipped with MEC resources (MEC-enabled UAV) that provides on demand communication capabilities to Ultra-reliable and Low-latency Communication (URLLC) services. We adopt a Continuous Time Markov Chain (CTMC) to analyze the overall node availability and reliability, while taking into account virtual host setup (repair) delays and failure events for Virtual Network Functions (VNFs) hosted on MEC-enabled UAVs. Our results show that the containerized VNF setup delays critically impact the admission process, whereas reliability is more prone towards VNF failures.
Análise do RED e sua Influência na Autossimilaridade do Tráfego de Rede
Authors: Moraes Jorge Magno Lopes , Callado Arthur de Castro
Published: October 2022

Com a descoberta de que o tráfego da rede possui a característica de autossimilaridade, alguns estudos buscaram diminuí-la, pois essa característica causa alguns efeitos negativos, como maior atraso na fila e congestionamento do tráfego. Entre os fatores trabalhados nas últimas décadas estão algoritmos de gerenciamento de filas, como Random Early Detection (RED). No entanto, os pesquisadores não estudaram a influência do RED na auto-similaridade mais profundamente. Afinal, esse algoritmo possui quatro parâmetros configuráveis (o peso da fila, a probabilidade máxima de queda e os limiares mínimo e máximo), que, quando modificados, podem levar a uma alteração no desempenho e, consequentemente, na autossimilaridade. Portanto, este artigo pretende verificar a influência do RED na auto-similaridade. Para isso, desenvolvemos um padrão para auxiliar na configuração dos limiares de RED. Também, mostramos o impacto de diferentes arranjos de limite na autossimilaridade e no desempenho do tráfego de rede. Além disso, comparamos algumas das melhores configurações de RED com Droptail.

Authors: Beltran Rafael D. , Oleques Kayuã P. , Kreutz Diego , Mansilha Rodrigo B. , Cordeiro Weverton
Published: October 2022

Após anos de pesquisa e desenvolvimento baseadas principalmente em metodologias analíticas e simulacional, a comunidade da área de ICN tem investido esforços em avaliações experimentais em direção a implantação da tecnologia. Porém, essa metodologia envolve desafios relacionados ao ambiente de testes, como heterogeneidade e falhas de nós e enlaces. Neste trabalho propomos um arcabouço denominado ICN-Stage para facilitar a execução de experimentos ICN distribuídos reprodutíveis e tolerantes a falhas. No ICN-Stage, os experimentos são realizados como uma peça teatral com processos (papéis) interpretados por nós (atores) em um testbed (palco). Um controlador (diretor) instrumenta os atores, garante a coordenação global, detecta as falhas dos atores e os substitui conforme necessário. Resultados obtidos em Minikube e no FIBRE evidenciam a viabilidade e potencialidades do ICN-Stage.

Authors: Pimentel Marlon , Abelém Antônio
Published: October 2022

A rede MetroBel foi uma rede pioneira no contexto nacional, lançada em 2007, conecta diversas instituições de ensino e pesquisa na região metropolitana de Belém/PA. Projetada há 15 anos, continua em produção, mas precisa evoluir para atender as novas demandas das instituições usuárias. Um dos entraves à essa evolução é a dificuldade para realizar testes para verificar novas configurações e adoção de novas tecnologias. Uma abordagem inovadora para superar esses desafios é o uso de cópias digitais (Digital Shadow) para tratar problemas do mundo real. Essa abordagem usa o meio digital para representar objeto do mundo real, vem ganhando popularidade na indústria e começa a ser empregada em cenários diversos. Este artigo propõe uma estratégia dividida em quatro etapas para criar uma Cópia Digital como uma alternativa para planejar e avaliar redes de computadores. Um estudo de caso da rede MetroBel é realizado para validar a proposta.
Optimization of a Polarization-Encoding System for Practical Quantum Key Distribution
Authors: Costa Hugo F. , Muga Nelson J. , Silva Nuno A. , Pinto Armando N.
Published: October 2022

We present a method for optimizing the waveplate’s voltage range of an electro-optic based electrical polarization controller for qubit encoding in discrete-variable quantum key distribution (QKD). By increasing the number of used waveplates, the maximum voltage range to generate each of the states-of-polarization required by a QKD protocol can be reduced. The proposed machine learning algorithm, particle swarm optimization, was validated through numerical and experimental results. Results show that transitions between six states of polarization used in QKD systems can be generated using a maximum voltage range of 10V in each waveplate.

Der Aufsichtsrat der Aktiengesellschaft
Authors: Oidtmann Julia
Published: October 2022

In the past, the supervisory board of the AG has undergone a transformation involving a professionalization of the body and its members. The author concludes that this has led to a significant change in the role and characteristics of the supervisory board, towards an active role as a "co-deciding control body". As a result of this development, the supervisory board is now perceived by institutional investors as an attractive interlocutor. The subsequent question of the permissibility of investor relations by the supervisory board ("whether") is located at the interface between corporate constitution under stock corporation law and capital market communication and is examined in the paper.
Integrative Wahlsysteme
Authors: Benken Björn
Published: October 2022

Ranked-choice voting systems, such as the spare vote, are particularly well suited to ensuring the integrative character of elections in Germany. So far, however, these electoral systems have been difficult to fit into existing German constitutional jurisprudence. This book provides suggestions on how to succeed in this task by redefining important concepts of electoral law from scratch. In doing so, it shows that integrated runoff elections and spare votes can not only be designed in accordance with the German constitution but are even constitutionally required. These new election procedures make it possible to implement the principles of political participation and democratic legitimacy contained in the principle of democracy in the best possible way.

Transdisciplinary Art-Science Identities and the Artification of Learning
Authors: Grushka Kathryn
Published: October 2022

Transdisciplinary art-science learning is linked to semiosis and the performative nature of learning. At the core of contemporary learning is sensemaking through images. We learn through how we perceive, remember, and imagine the world. An ethics-approved inquiry looked at the artmaking practices of gifted secondary school students between the ages of 15 and 17 years (n = 108) with a focus on their art-science performative learning. The study applies Deleuzoguattarian thinking and other post-structural perspectives on contemporary representational practices for learning and communication in art-science spaces. One of the research key findings is that artified visual pedagogies can both transverse and/or facilitate meaning-making across art-science spaces and brings forth the creation of science-linked identities. Educators must now engage with the idea that visual reasoning as performative action is now the connecting pedagogy in all epistemic fields.
MELT INCLUSIONS IN OLIVINE AS A SOURCE OF INFORMATION ON THE COMPOSITION AND EVOLUTION OF DEEP MELTS OF AILLIKITES (ULTRAMAFIC LAMPROPHYRES) OF THE ILBOKICHI UPLIFT, THE SW SIBERIAN PLATFORM
Authors: Starikova A. Е. , Prokopyev I. R. , Doroshkevich A. G. , Kargin A. V. , Nosova A. A. , Kovalev S. A.
Published: October 2022

Aillikites are kimberlite-like rocks, important for understanding the composition and processes occurring in the mantle. Melt inclusions represent a reliable source of information. The paper provides the first results of studies (Raman, EDS) on primary and secondary melt inclusions in olivine from the Ilbokich uplift aillikites. The composition of primary inclusions is close to that of parent melt of aillikites. It was significantly enriched in CO2, H2O, phosphorus and titanium. Phlogopite, diopside, dolomite, calcite, apatite, Ti-containing phases (brookite, perovskite, Ti-magnetite) and lizardite were identified in these inclusions. The similarity of the composition and ratios of the daughter phases with the aillikite matrix indicates a slight change in the parent melt when it is rising to the surface. As to the secondary inclusions, there are wide variations in compositions and a smaller amount of silicates, as compared to the primary ones. The main daughter phases are carbonates, e.g. dolomite, calcite, magnesite and alkaline carbonates. In addition, phlogopite, clinopyroxene, apatite, halite, pyrrhotite and magnetite, graphite and CO2 were discovered. The variability of the compositions of the secondary inclusions might be due to the silicate-carbonate immiscibility that appeared during the rising of the aillikite melt at pressures <4 GPa.
Experiência distópica nas narrativas Animal Farm, de George Orwell (1945) e Fazenda Modelo – Novela Pecuária (1974), de Chico Buarque
Authors: Silva Agnaldo Rodrigues da , Oliveira Thainá Aparecida Ramos de
Published: October 2022

O presente artigo, pensado teoricamente pelo viés da distopia, objetiva analisar as narrativas Animal Farm, de George Orwell (1945) e Fazenda Modelo – Novela Pecuária (1974), de Chico Buarque, produções que articulam representações sociais complexas, geradas em contextos históricos de distintas motivações culturais e políticas. A escolha do corpus deu-se porque os enredos apresentam a configuração do autoritarismo e também de governos totalitários e ditatoriais, fatores esses que possibilitam um debate sobre o conceito de distopia e sobre a função da literatura, que não se fixa apenas na ideia de fruição estética, mas se torna um elemento capaz de questionar as várias esferas sociais, culturais, políticas e humanas que promovem os movimentos de imanência e transcendência entre a ficção e a história.
Is the Time Right for a Paradigm Shift? Where we have been and where we Might be Going
Authors: Verrecchia P.J.
Published: October 2022

Over the years there have been a number of paradigms and concomitant shifts in criminal justice. Each paradigm shift follows a general discontentment with the existing paradigm. This is crucial because with change comes a new operating system designed to, at the least, protect society. When the paradigm is not doing its job, crisis can ensue. Current attitudes towards the criminal justice system raise the question, are we in a moment of crisis? This article explores the history of shifts in the criminal justice system, where we are now, and were we might be going.
Toenail Dust as a Potential Occupational Hazard in Podiatric Medicine: A Comprehensive Literature Review
Authors: Saini Komal , Tran Tiffany , Khosravi Melody , Krishnan Jannani , Tower Dyane E. , Shih Chia-Ding
Published: October 2022

Background: Debridement of toenails is a common procedure that leads to the production of nail dust aerosols in the work environment. Previous studies indicate that inhaled nail dust can cause respiratory distress and eye irritation. This comprehensive review aimed to assess the available literature on the effect of nail dust exposure and to evaluate nail dust as a potential occupational hazard for podiatric physicians.

Methods: A comprehensive literature search was conducted via PubMed, Google Scholar, CINAHL, Cochrane Library, and ClinicalTrials.gov. Risks of bias of the collected studies were evaluated using various assessment tools to match the type of study design. A qualitative analysis of the included studies was performed, from which primary and secondary outcome measures were extracted: prevalence of symptoms and specific microorganisms in nail dust.

Results: Of 403 articles screened, eight met the inclusion criteria. The primary outcome measure resulted in a pooled prevalence of eye-related symptoms being the most consistent symptom reported (41%–48%). The secondary outcome measure resulted in a pooled prevalence of Trichophyton rubrum (9.52%–38%) and Aspergillus (11.11%–35.48%) as the most common microorganisms present in nail dust.

Conclusions: From the included eight articles, we found that nail dust is a potential occupational hazard, especially for those exposed more often. Aspergillus and T rubrum are most commonly associated with nail dust leading to development of respiratory illness. It is important to take preventive measures in podiatric medical clinics by using improved and efficient personal protective equipment for workers exposed to nail dust. Detailed health safety guidelines can be developed to decrease respiratory symptoms and diseases from nail dust exposure.
A 30-Year-Old Man with an Unusually Large Untreated Plantar Fibrolipoma That Disrupted Ambulation and Required Operative Excision
Authors: Positano Rock CJay , Trepal Michael J. , Ciaramella Michael , Positano Rock G.
Published: October 2022

A 30-year-old man working as a waiter presented with a progressively enlarging and symptomatic soft-tissue mass on the plantar medial aspect of his left foot. The mass was painful and disrupting ambulation, despite footwear modifications. He ultimately underwent excision of what was a determined to be a fibrolipoma, returning to his regular shoes and all activities. Plantar neoplasms, even when benign, can grow to sizes that can result in significant disability. If left untreated, particularly in individuals engaged in occupations requiring frequent standing or walking, excision of the mass will often require a more aggressive operative approach.

Authors: Hiramitsu Takahisa , Tomosugi Toshihide , Futamura Kenta , Okada Manabu , Goto Norihiko , Ichimori Toshihiro , Narumi Shunji , Uchida Kazuharu , Watarai Yoshihiko
Published: October 2022

Background

Hand-assisted laparoscopic donor nephrectomy (HALDN) is widely performed to minimize burden on living kidney donors. However, hand port-site infections after HALDN may occur. This study aimed to assess the impact of donor characteristics including preoperative comorbidities and operative factors on hand port-site infection after HALDN.

Methods

In this single-center, retrospective cohort study, 1,260 consecutive HALDNs for living-donor kidney transplantation performed between January 2008 and December 2021 were evaluated. All living donors met the living kidney donor guidelines in Japan. Hand port-site infections were identified in 88 HALDN cases (7.0%). To investigate risk factors for hand port-site infection, donor characteristics including preoperative comorbidities such as hypertension, glucose intolerance, dyslipidemia, obesity, and operative factors such as operative duration, blood loss, preoperative antibiotic prophylaxis, and prophylactic subcutaneous suction drain placement at the hand port-site were analyzed using logistic regression analysis.

Results

In the multivariate analysis, significant differences were identified regarding sex (P = 0.021; odds ratio [OR], 1.971; 95% confidence interval [CI], 1.108–3.507), preoperative antibiotic prophylaxis (P < 0.001; OR, 0.037; 95% CI [0.011–0.127]), and prophylactic subcutaneous suction drain placement at the hand port-site (P = 0.041; OR, 2.005; 95% CI [1.029–3.907]). However, a significant difference was not identified regarding glucose intolerance (P = 0.572; OR, 1.148; 95% CI [0.711–1.856]). Preoperative comorbidities may not cause hand port-site infections within the donors who meet the living kidney donor guidelines. Preoperative antibiotic prophylaxis is crucial in preventing hand port-site infection, whereas prophylactic subcutaneous suction drain placement may increase the risk of hand port-site infection.

Authors: Basany Laxman , Aepalapala Roja
Published: October 2022

Organophosphorus Compounds (OPC) are widely used as pesticides, and poisoning due to OPC is very rare in neonates. A 12-day- old female neonate was admitted with gasping respiration, excessive oral secretions and cold extremities. She had frothing from mouth and nose with an offensive odour, was hypothermic, hypotonic, cyanosed and was in mild stupor. Pupils were pin pointed, capillary refill time was 4-5 sec and had bilateral crepitations of lungs on auscultation. The baby was intubated, given 0.1 mg of atropine followed by 0.9% saline bolus and gastric lavage. She was treated with empirical antibiotics, atropine, Pralidoxime (PAM) and respiratory support. The baby responded well to treatment and was discharged on 10th day of admission. This could be the second case of Organophosphorus (OP) poisoning with homicidal intention reported in neonates.

Synthesized composites were characterized through UV-spectrophotometer, XRD, SEM, EDX and FTIR analysis. SEM and EDX images confirmed surface morphology of ordinary mesoporous nano silica (mNs) and Fe & Zn embedded mNs. In XRD pattern of mNs peaks absence indicate that nano silica synthesized by sol-gel method was amorphous whereas reduced graphene oxide (rGO) synthesized in crystalline form. FTIR spectra of Zn and Fe loaded mNs and rGO showed that encapsulation of zinc and iron by mNS and rGO was successful. Results of experiment indicate, twice foliar application of 60 ppm Zn+ 30 ppm Fe through mNs (T6) and 40 ppm Zn+20 ppm Fe through rGO (T8) exhibited significantly higher economic and biological yields of both crops over conventional and Control. With increasing doses of nano zinc and iron through mNs composite capsules, significant increase in nutrients content and uptake by cabbage and cauliflower was observed in comparison to control. Whereas, increasing doses of nano zinc and iron application through rGO lead to a considerable reduction in nutrient content and thus hamper their uptake. Thus, T6 and T8 treatments were best pronounced in terms of yields, nutrients uptake and enriching biomass by iron and zinc content in cabbage and cauliflower, respectively. Compared to control, quality of cabbage head and cauliflower curd biomass in terms of Fe and Zn content, protein and phenol content were significantly more with  40 ppm Zn+20 ppm Fe (T8) and 60 ppm Zn+30 ppm Fe (T6) through  rGO and mNs , respectively. Available zinc and iron in soil was unaffected  by application of zinc and Fe through mNs and rGO in crops.

This dissertation attempts to assess assessed common factors contributing to divorce among couples in Zanzibar. The study employed a qualitative research approach where by interview and documentary reviews were used as a method of data collection. A total of 35 participants involved in this study, where by 30 participants were divorced men and women who were obtained through snowball sampling and five Kadhis who were purposely selected from both Unguja and Pemba districts. Thematic analysis procedure was applied to analyze data. The study found that there is a high prevalence of divorce among Zanzibar couples. The interviewees were particularly concerned about the overwhelming number of divorces which was on a steady uptrend. The study identifies factors which lead to the rate of divorce in Zanzibar and found that lack of tolerance among the couples, family interference of their children marriage, psychological and emotional abuse were the major common factors contributing to divorce among couples in Zanzibar. The study concluded that divorce problem is at larger extent and participants are aware of the magnitude of the divorce and it occurs every day and everywhere in Zanzibar. Thus this is a serious problem among young couples and children. In addition, family interference of children marriage and social networking, immaturity, sexual dissatisfaction, psychological and emotional abuse, drug abuse, poverty, belief on financial expenditure, financial stress contributes more to divorce among Zanzibar people. This leads to majority of young couples to face frequently fights in their marriages hence influencing divorce.

An experiment was laid out with six wheat genotypes K-9162, K910-30, DBW-16, AAI-16, K-911, and NW-1014. This study was conducted during winter season 2020-2021 at the Student Instructional Farm and in the laboratory of Plant Molecular Biology and Genetic Engineering at Acharya Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhya –224 229 (U.P.) in Randomized Block Design (R.B.D.) The wheat genotypes were exposed to heat stress by delayed sowing of 60 days from the normal date of sowing (15 January 2021) so that reproductive stage of wheat can experience heat stress. The field preparation and normal agronomic practices were followed as per need of the crop. The wheat genotypes K-9162, K910-30 and K-911 showed less reduction in yield and yield components over the DBW-16, AAI-16 and NW-1014 wheat genotypes. Therefore, on the basis of less reduction in yield and yield components under heat stress, K-910-30, K-911 and K-9162 were showed the significant tolerant while the other genotypes like DBW-16, NW-1014 and AAI-16 were found high yielding under normal condition but also showed high reduction in yield under heat stress condition.

The evaluation of varieties for a particular region is an important process in order to screen the potential cultivars for any specific region or climate. Although the varieties may express a unique behaviour under certain area, but it may fail or sustain that peculiar character when grown under different location. Along with varieties, planting time significantly affect the crop production. Therefore, standardization of planting time is very important to get a good growth and excellent quality of cut flowers. By using staggered planting, the flowering period may also be extended for  fetching  a  good  price during different occasions. The present investigation comprised five oriental lily varieties along with three planting time (1st fortnight of October, 2nd fortnight of October and 1st fortnight of November) and observations were recorded for various vegetative  parameters.  Out  of  the  three-planting  time,  the varieties planted during 1st  fortnight of October performed better resulting in terms of maximum plant height,  number  of  leaves,  leaf  length,  leaf  width  etc. Among the varieties, St. Andrews performed overall best with respect to highest percentage of bulb sprouting, plant height, leaf length, leaf width etc.

Background: Maternal health indicators vary with the dynamics of care delivery and utilization. Active paternal support remains a key driving force towards efficient management of maternal health

Objective: To assess male partners involvement in maternal health in Anambra State Nigeria.

Materials and Methods: Multistage sampling technique were used in enrolling a cross- section of 372 male partners in urban and rural communities in Anambra Nigeria, into this survey. Semi- structured questionnaires were designed from relevant literatures, and administered by face to face interviews on consenting enrollees. Statistical analysis of data was done using Statistical Package for Social Sciences version 22, tests of association, by chi square at p<0.05.

Results: Majority, 307 (82.5%) of respondents reported awareness of paternal role in maternal health, with the commonest sources of information as television, 145 (39%); radio 125 (33.4%); social media 115 (30.9%). Also, 301 (97%) respondents knew about paternal role, with financial support as the commonest form reported, 330(58.7%). They reported positive attitude to, and 302 (88%) high practice of male partners role in maternal health. Statistically significant associations were found between practices and age (p=<0.001) as well as occupation (p=<0.001).

Conclusions: This study finds apparently high awareness of, high knowledge of, positive attitude to, and high practice of paternal role in maternal health, which is associated with age and occupation. There is need to sustain the reported levels of awareness, knowledge, attitude and practice of paternal role via quality assured need- targeted education on maternal health.

In hilly places, constructing and building forest roads requires a variety of economic and environmental criteria. To develop a solution that minimize construction, maintenance, and adverse environmental effects, road management must take into account as many alternative alignment options as they can. The idea of this research was to plan the network of forest roads in the Periyar Tiger Reserve's mountainous region using Geographic Information Systems (GIS) based on Multi-Criteria Decision Analysis (MCDA). These techniques were applied using the study area's slope, aspect, Elevation, NDVI, drainage and susceptibility to landslides datasets. In addition, the road network created using the GIS-MCDA approach was contrasted with the existing road networks. The key elements that affect the road network in the research area were found, and the necessary maps were produced and categorized. The maps were graded using MCDA to determine the weight of both useful aspects as the next step in determining the significance and role of the aforementioned elements in the cost of road building. Second, using the Arc GIS 10.4 weighted overlay analysis tool, a forest potential map for road building was created by overlaying the weighted maps of the influencing elements. Thirdly, the competence of a map was divided into Six categories: very high, high, moderate, low, very low and Restricted roading Suitability. Finally, using a weighted overlay method to combine the road network and road planning potential map, the existing road network was analyzed. The findings of this study indicated that the majority of existing roads were located in high and moderate road Suitability. A small percentage was located in low road Suitability, which can be taken into account for alignment. These results suggested that the design of forest road planning in hilly areas can be more precisely accomplished using the multi-criteria evaluation method. Similar method as used in this study can be applied to other forested sites.

Importance

Understanding of the economic burden of recurrent vestibular causes of vertigo and areas contributing to the cost is needed.

Objective

To analyze and identify the factors contributing to the direct medical costs associated with Ménière disease (MD), vestibular migraine (VM), and benign paroxysmal positional vertigo (BPPV).

Design, Setting, and Participants

This economic evaluation used MarketScan Commercial Database claims data from 2018 to identify the non-Medicare patient population with the diagnoses of MD, VM, or BPPV. Data were analyzed January 1 to December 31, 2018.

Main Outcomes and Measures

The total direct medical costs associated with MD, VM, and BPPV.

Results

A total of 53 210 patients (mean [SD] age, 47.8 [11.8] years; 67.6% female) were included in this study, with 34 738 normal comparisons. There were 5783 (10.9%) patients with MD, 3526 (6.6%) patients with VM, and 43 901 (82.5%) patients with BPPV in the data set. Mean age and sex were different across the different vestibular disorders. Across the different groups, patients with no comorbidities or with a Charlson Comorbidity Index score of zero ranged from 98.4% to 98.8%. Around 5% of patients were hospitalized with inpatient stay lasting between 4.6 and 5.2 days. After adjusting for age, sex, and comorbidities, there were large differences in mean adjusted annual payments/direct costs across the different groups (MD, $9579; VM, $11 371; and BPPV, $8247). This equated to a total incremental estimated cost of $60 billion compared with the normal population. The number of outpatient brain magnetic resonance imaging or computed tomography scans per patient ranged anywhere from 1 to 20, while the number of inpatient brain magnetic resonance imaging or computed tomography scans per patient ranged anywhere from 1 to 6. A heat map of the total cost expenditure indicated that the costs were concentrated around the Midwest, Lake Michigan, and the East Coast.

Conclusions and Relevance

In this economic evaluation, the 3 most common causes of recurrent vertigo—MD, VM, and BPPV—had considerable medical costs associated with them. Extraneous imaging orders and vestibular testing are factors to consider for cost reduction. However, further research and widespread education is needed to optimize the diagnosis, treatment, and care of patients presenting with vestibular disorders or dizziness.
