Authors: Lemes Elisandra , Sanches Camila Garcia Salvador , Mello Adalgisa Loureiro de , Chassot Francieli
Published: December 2021

A sífilis é uma Infecção Sexualmente Transmissível (IST) amplamente conhecida no Brasil e de fácil tratamento, porém com pouco controle nos últimos anos, sendo ainda um importante problema de saúde pública. O objetivo deste estudo foi avaliar as características epidemiológicas e fatores condicionantes de casos notificados de Sífilis adquirida e congênita no município de Palmas – PR. A metodologia baseia-se em estudo epidemiológico, descritivo, do tipo levantamento retrospectivo exploratório de caráter transversal e qualitativo, por meio de base de dados obtidos pela Vigilância de Epidemiologia de Notificações SINAN-NET, referentes aos casos notificados de sífilis congênita e de sífilis adquirida em residentes no município de Palmas – Paraná no período de janeiro de 2015 a dezembro de 2017. Os resultados da pesquisa apresentaram um total de 159 casos de sífilis adquirida registrados entre os anos de 2015 a 2017 no município de Palmas/PR, destacando-se o aumento considerável de 36% dos casos notificados no ano de 2017. O número de casos notificados de sífilis adquirida foi maior para o sexo feminino, havendo uma diferença de oito por cento (8%) entre os gêneros para os três anos. O índice maior de casos notificados de sífilis em gestantes foi de 60% para a faixa etária entre 20 a 29 anos e 35,4% para aquelas com ensino fundamental incompleto. O não tratamento dos parceiros se dá pela falta de comparecimento a unidade de saúde e a falta de pós contato com a gestante. A sífilis congênita apresentou aumento significativo no ano de 2017 (51%) com concentração maior no bairro Lagoão. Os registros de tratamento para todos os anos se apresentaram de forma inadequada pelos pacientes, demonstrando uma carência na sua efetivação, e ainda se apresentando como problema grave de saúde pública. Para pesquisas futuras sugere-se campanhas disseminadas em cada bairro, com maior frequência e atenção redobrada nos bairros que apresentam maiores índices.

Authors: Pabich Marek , Gajowiak Magda
Published: December 2021

The Universal Design aims to improve the functionality and accessibility of urbanized areas for all users, regardless of their physical, perceptual, or intellectual capability. This task is also a priority for the Polish government, however legislations do not provide clear solutions for supporting people with perceptual limitations. Contemporary technologies can support the spatial orientation of people with disabilities, allowing them to get around independently and safely. Bluetooth Low Energy (BLE) technology, unlike to the global positioning system (GPS), allows accurate indoor location and navigation. The purpose of this article is to discuss and benchmark two BLE-based navigation and information systems: The GuideBeacon supported by the IBeaconMap software and Totupoint. The result is a summary of the key functionality and limitations of both solutions and an indication of the prospects for further development.
Lærarstudentar si oppleving av ei mentorordning i norsk grunnskulelærarutdanning
Authors: Opheim Bente , Faye Reidun
Published: December 2021

Mentorordningar, der studentar blir rettleia av ein vidarekommen student eller tilsett, har fått mykje merksemd i høgare utdanning dei siste åra. I norske styringsdokument for sektoren ligg det ei forventning til at slik mentorverksemd skal bli utvikla i større skala og bidra til kvalitetsarbeidet til universitet og høgskular. Samstundes viser oversiktsstudiar at omgrepet blir forstått svært ulikt og famnar om ei rekke forskjellige former for samarbeidslæring og at det finst lite forskingsbasert kunnskap om korleis slike mentorordningar bidrar til å heve kvaliteten ved norske høgare utdannings­institusjonar. I denne artikkelen presenterer vi resultat av eit mentoropplegg gjennom­ført med førsteårsstudentar og masterstudentar ved grunnskulelærarutdanninga ved Høgskulen på Vestlandet. Studentane rapporterte at dei vart meir engasjerte, motiverte og la inn høgare arbeidsinnsats som resultat av mentorordninga. I artikkelen utforskar vi på kva måte sjølve mentorordninga kan ha verka motiverande. Vi tek utgangspunkt i sjølvbestemmingsteori (SDT), som har som premiss at for å oppnå høgare motivasjon og engasjement må tre basale psykologiske behov vere til stades: kompetanse, autonomi og tilhøyrsle. Gjennom spørjeskjema og intervju undersøker vi korleis mentorordningar ser ut til å ha hatt effekt på studentane si oppleving av kompetansen dei har tileigna seg, på kva måte deira autonomi har blitt ivaretatt eller utfordra, og korleis ordninga har verka inn på kjensla av tilhøyrsle og integrasjon. Både førsteårsstudentane og mentorane opplevde styrka kompetanse og positive meistringserfaringar som følgje av mentor­opplegget. Handtering av autonomi syntest å vere ei utfordring for begge student­grupper, medan behovet for tilhøyrsle vart verdsett høgt, men i ulik grad innfridd.
Peer feedback med videoannotering för att främja lärarstudenters reflektion
Authors: Nagel Ilka , Engeness Irina
Published: December 2021

Peer feedback är ett centralt element av bedömning för lärande, och användning av video och videoannotering har potential att främja lärarstudenters kritiska reflektioner kring deras undervisning. I den här designstudien undersökte vi feedback som första­årsstudenter gav med videoannoteringsverktyget Studio på sina medstudenters filmade muntliga presentationer och visar hur verktyget påverkade feedbackprocessen. Data består av den skrivna feedback som studenterna skapade med videoannoterings­verktyget, studenternas svar på en undersökning och två semistrukturerade fokusgrupp­intervjuer. Vi använde kvalitativa metoder för dataanalysen. Resultaten visar att mer än hälften av alla kommentarer var positiva och bekräftande (beröm) och bara ett fåtal erbjöd råd för förbättring. Studenterna tyckte att feedbacken var detaljerad, att video­annoteringsverktyget gjorde det möjligt att kommentera vid konkreta ögonblick i presentationen och drog slutsatsen att processen med att både ge och få denna typ av feedback ökade deras förmåga till självreflektion. Även om studenterna uttryckte oro över att ge feedback till medstudenter, så var de positiva till att använda videoannotering för att ge respons och beskrev att processen bidrog till deras lärande och var relevant för deras framtida verksamhet som lärare. Resultaten visar att det är viktigt att lärarutbildare är medvetna om potentialen och begränsningarna med videoannoteringsverktyg för att förbättra pedagogiska processer och studenters reflektion kring deras eget sätt att under­visa. Resultaten pekar också på att studenternas färdigheter i att ge feedback av hög kvalitet behöver utvecklas mer.
Could COVID-19 Boost Greece’s Village Revival?
Authors:   Metsovion Interdisciplinary Research Centre (MIRC), National Technical University of Athens, DOLOGLOU Natali
Published: December 2021

Abstract: In the last decades, Greek villages, especially in mountainous and remote areas, are gradually depopulated and suffer from youth out-migration, school closures and unemployment. During this COVID-19 outbreak, there is an increasing trend of villages as destinations for domestic tourism for short holidays or longer stays. At the same time, this pandemic leads to a significant increase of remote working practices. This article explores the prospect for the revival of traditional villages via an Albergo Diffuso (AD) model with adjustments for both visitors and temporary distance-working residents. We analyze the AD concept as it has been employed in Italy, make minor adjustments to it, and investigate the applicability of such a model in order to overturn the current depopulation of rural and mountain villages in Greece and improve the wellbeing of the local communities. To this end, we present a comprehensive SWOT analysis and discuss the findings. Our approach lays the groundwork for further research that is required to successfully implement AD in mountainous villages.

This paper demonstrated the fuzzy AHP combined with fuzzy VIKOR technique integrated with essentials of weight in order to overcome the risk evaluation process of the uncertainty in subjective perception and experience of human. Gas turbine has considerably expanded its role in several areas subsequent to the improvement in high efficiency and clean energy such as aviation and marine propulsion systems, electric power stations, and natural gas and petroleum transportation. However, the cost of various industrial plants and their relevant maintenance appear to be extremely expensive to be operated by these gas turbines. This paper aimed to cope with the essential elements of gas turbine including hydraulic-pneumatic equipment, electronic control equipment, and bearing equipment. The results have proved the bearing equipment to have been the most effected alternative, as being ensued by hydraulic-pneumatic equipment and electronic control equipment.
INVESTIGATION OF WELDER SELECTION PARAMETERS BASED ON FUZZY ANALYTIC HIERARCHY PROCESS IN SHIPBUILDING
Authors: Ozkok M
Published: December 2021

Today, it is very significant to select appropriate welders in shipbuilding industry. The fact that there is a really tough competition between shipyards triggers the increasing of welder quality. Higher welder quality means higher quality welding workmanship. If a shipyard has a high quality workmanship, it has bigger competitive power than its rivals. Therefore, shipyard management must take welder selection into more consideration. In this study, the weights of welder selection parameters of shipyards were determined by utilizing Chang’s extent analysis method. In this way, it is aimed to understand the point of view of shipyards in selecting welder. In addition, taking into account the important parameters in welder selection, the welders can improve their weak sides. Consequently, the results obtained from this study are believed to be a guide for the people who want to work as a welder in shipyards.
FAHP FOR SELECTING TRANSPORT MODES OF TAIWAN OFF-SHORE ISLANDS’ MILITARY LOGISTICS
Authors: Wang Y-J , Han T-C , Chung C-C , Fang C-L
Published: December 2021

Three off-shore islands of Taiwan: Penghu, Kinmen and Matsu are critical in tactical position for Taiwan military, but lack of scarcity resource. Therefore, logistics is very important especially for the off-shore islands. Practically, most of the goods and materials are transported to the islands in the way of shipping and air transportation by Taiwan. However, the severe weather of the islands makes the transportation difficult or even to delay, which is a serious problem for the military logistics of the islands. To raise transportation performance, a proper evaluation method is necessary for military logistics to select the best transport mode based on reducing cost and emphasizing efficiency. Generally, analytic hierarchy process (AHP) may be a method in the selection of transport modes for Taiwan off-shore islands’ military logistics. However, some computation procedures in AHP are hard or complicated especially for processing numerous interviewees’ messages. To resolve the above tie, we utilize fuzzy analytic hierarchy process(FAHP) in selecting transport modes for Taiwan off-shore islands’ military logistics in this paper. After integrating interviewees’(i.e., querying soldiers’) opinions into fuzzy pair-wise comparison matrices, FAHP, being different from AHP, simply and efficiently yields priorities of the fuzzy pair-wise comparison matrices to find the best transport mode of Taiwan off-shore islands’ military logistics.
A POLICY-MAKING FRAMEWORK FOR ENHANCING THE KAOHSIUNG PORT’S ECONOMIC RESILIENCE
Authors: Tai H H , Yang C C
Published: December 2021

This paper is a revised and expanded version of a paper entitled ‘Influential indicators for measuring Kaohsiung port resilience’ presented at the International Forum on Shipping, Port, and Airports (IFSPA 2013), Hong Kong Polytechnic University, Hong Kong, 3–5 June 2013.

The analytic hierarchy process (AHP) method commonly used in the issue of decision making was performed in this study to propose a policy-making framework for enhancing the Kaohsiung port’s economic resilience. A three-level hierarchical structure with 19 attributes is proposed and tested. Results indicate that adjusting the shipping policy is perceived as the most critical strategic dimension to enhance container port resilience. This is followed by increasing incentives, adjusting port operational strategy and exploiting market opportunities. Overall, results show that the five most important strategies for enhancing international container ports’ resilience are training of international marketing personnel, economic deregulation of shipping market across the Taiwan-Strait; subsidising the throughput of containers transhipment, subsidising coastal shipping operations and the alteration of dedicated terminals for rent. This study contributes in proposing a policy-making framework to enhance the container port’s economic resilience, and this framework could also be generalised to other ports.
HYDRODYNAMIC INTERACTION BETWEEN SHIPS AND RESTRICTED WATERWAYS
Authors: Lataire E , Vantorre M
Published: December 2021

In open and unrestricted waters the water displaced by a forward sailing vessel can travel without major obstruction underneath and along the ship. In restricted and shallow sailing conditions, the displaced water is squeezed between the hull and the bottom and/or the bank. This results in higher flow velocities and as a consequence a pressure drop around the same hull. In the vicinity of a bank this pressure drop generates a combination of forces and moments on the vessel, known as bank effects. The major achievement of the presented research is the development of a realistic and robust formulation for these bank effects. This knowledge is acquired with an extensive literature study on one hand and with dedicated model tests carried out in different towing tanks on the other. The majority of the utilised model tests were carried out in the shallow water towing tank at Flanders Hydraulics Research in Antwerp, Belgium. The data set on bank effects consists of more than 8 000 unique model test setups (which is by far the most elaborate research ever carried out on this subject). These model tests provide the input for the analysis of bank effects and the creation of the mathematical model.
A VIRTUAL PISTON-TYPE WAVE MAKER BASED ON OPENFOAM
Authors: Yao J
Published: December 2021

OpenFOAM is an open source CFD (Computational Fluid Dynamics) toolbox and recently attracts many researchers to develop codes based on it for their own applications. In order to numerically generate waves based on the wave-maker theory for a piston motion, numerical improvements have been done on the base of OpenFOAM by the author. In gen- eral, the present new tool can be employed to simulate wave generation as long as the piston motion is given. This paper presents the related computational procedure and simulations for generating relatively long finite-amplitude waves ac- cording to Madsen’s second-order wave-maker theory. The sensitivities of the computed incident wave profile to grid density and time step are investigated for the case of generating a wave with permanent form. The simulation accuracy is validated by comparison with the analytical solution and available experimental data.
BACKSTEPPING CONTROL OF NONLINEAR ROLL MOTION FOR A TRAWLER WITH FIN STABILIZER
Authors: Demirel H , Doğrul A , Sezen S , Alarçin F
Published: December 2021

A backstepping control design procedure for nonlinear fin roll control of a trawler is presented in this paper. A roll equation consisting of linear and nonlinear damping and restoring moment on the roll response is expressed. Flow analyses are carried out for a scaled model of trawler type fishing vessel including fin stabilizers on both sides of the hull. The fin stabilizer geometry is chosen as NACA 0015 foil section which is widely used in the literature. The flow analyses are performed by using a commercial computational fluid dynamics (CFD) software based on finite volume method. The flow problem is modeled in a 3-dimensional manner while the flow is considered as steady, incompressible and fully turbulent. The numerical model consists of the ship wetted surface and the fin stabilizer in order to investigate the hull-fin interaction. Non-dimensional lift coefficients of the fin stabilizer for different angles of attack are gained. Both controlled and uncontrolled roll motions are examined and simulated in time domain for the maximum lift coefficient. Backstepping controller for roll motion has given a rapid and precise result.

Published: December 2021

In order to evaluate the ship trajectory more reasonable based on the quantitative information. This paper presents a new approach to evaluate the inward-port single ship trajectory quantitatively based on ship-handling simulator. First, a ship tracking points generating algorithm is proposed to generate sufficient tracking points in order to address the issue that the sample information is not enough on the ship simulator. Second, three reference tracking belts are established based on the sample data and cloud drop contribution degrees for the scenario that the collected samples information are enough. Finally, a quantitative score evaluation method that combines the qualitative information and the quantitative information is proposed, the similarity measurement results verify that the MES algorithm is more reasonable, the evaluation results of inward-port single ship trajectory illustrative that the proposed method is effective when applied to quantitative evaluation problems.
HULLFORM & HYDRODYNAMIC CONSIDERATIONS IN THE DESIGN OF THE UK FUTURE AIRCRAFT CARRIER (CVF)
Authors: Campbell-Roddis M E
Published: December 2021

The author is to be congratulated in producing a paper for the journal on an important aspect (hydrodynamics) of a design, which was taken to a considerable level of definition before not being proceeded with. The fact that we so rarely get visibility of the thinking and effort behind “abortive” designs – so very little was allowed to be preserved of the cancelled CVA01 of the 1960s – and that this can be compared to the separately evolved, subsequently fully design and, now in 2017, about to go into service QUEEN ELIZABETH (QEC) carrier, makes this a very worthwhile document for the Transactions.

Not only can the various detailed conclusions on the hydrodynamically related design choices be read for their input to the BAE Systems alternative to the Thales design, that was finally developed into the QEC (see S Knight’s 2009 RINA Conference paper), the paper also provides general insights into the interaction of one specific topic (hydrodynamics) with wider design developments. This can be instructive to future designers of complex ships – not just aircraft carriers. It could be argued that despite the growing capabilities of CFD tools, that there still appears to be a need for substantial model testing of discrete elements of the hydrodynamic design, as described. Would the author like to comment as to whether he sees this dual need for CFD and physical model testing likely to continue whenever new designs “are just that little bit too different” and how one might judge the latter?

Authors: Mathew J , Sgarioto D , Duffy J , Macfarlane G , Denehy S , Norman J , Cameron A , Eutick N , Van Walree F
Published: December 2021

Hydrodynamic interactions during Replenishment at Sea (RAS) operations can lead to large ship motions and make it difficult for vessels to maintain station during the operation. A research program has been established which aims to validate numerical seakeeping tools to enable the development of enhanced operator guidance for RAS. This paper presents analysis of the first phase of scale model experiments and focuses on the influence that both the lateral and longitudinal separations between two vessels have on the interactions during RAS. The experiments are conducted in regular head seas on a Landing Helicopter Dock (LHD) and a Supply Vessel (SV) in intermediate water depth. The SV is shorter than the LHD by approximately 17%, but due to its larger block coefficient, it displaces almost 16% more than the LHD. Generally, the motions of the SV were larger than the LHD. It was found that hydrodynamic interactions can lead to large SV roll motions in head seas. Directions for future work are provided.
AN OPTIMIZED ENERGY-EFFICIENT PATH FOLLOWING ALGORITHM FOR UNDERACTUATED MARINE SURFACE SHIP MODEL
Authors: Xu Haitong , Guedes Soares C
Published: December 2021

An optimized path following guidance law is proposed for path-following of an underactuated surface ship. The main purpose of the proposed guidance law is to make a marine vessel travel with more energy efficiency. A combined feedback and feedforward controller is used for the heading control. The feedforward term is designed based on the well-known Nomoto model, whose parameters are estimated using least-square support vector regression. In order to achieve optimal operation of a marine vessel, a global optimization algorithm is employed to search the regularization factors, which are the trade-off between the total cross-track errors and total control energy. The simulation studies are carried out to demonstrate the performance of the proposed guidance law. The proposed method is an effective and practical guidance law and provide an optimal option for marine navigator.
Online Estimation of Terminal Airspace Sector Capacity from ATC Workload
Authors: Mohamed Majeed
Published: December 2021

Neural Partial Differentiation (NPD) approach is applied to estimate terminal airspace sector capacity in real-time from the ATC (Air Traffic Controller) dynamical neural model with permissible safe separation and affordable workload. A neural model of a multi-input-single-output (MISO) ATC dynamical system is primarily established and used to estimate parameters from the experimental data using NPD. Since the relative standard deviations of these estimated parameters are lesser, the predicted neural model response is well matched with the intervention of ATC workload. Moreover, the proposed neural network-based approach works well with the experimental data online as it does not require the initial values of model parameters that are unknown in practice.

Authors: Sheleme Tadesse
Published: December 2021

Metformin, the only biguanide oral antidiabetic agent available, was first used clinically in the late 1950s. Metformin remains the first-line pharmacologic treatment for type 2 diabetes patients. It can be used as a single agent or in combination therapy with other antidiabetes agents, including insulin. Metformin is absorbed predominately from the small intestine. It is rapidly distributed following absorption and does not bind to plasma proteins. It is excreted unchanged in urine. The elimination half-life of Metformin during multiple dosages in patients with good renal function is approximately 5 hours.

Authors: Zhou Yue , Wu Jianzhong
Published: December 2021

Peer-to-peer (P2P) energy trading is an innovative approach for managing increasing numbers of Distributed Energy Resources in microgrids or local energy systems. In P2P energy trading, prosumers and consumers directly trade and exchange power and energy with each other. The development of P2P energy trading is described in five key aspects, that is, market design, trading platforms, power and ICT infrastructure, regulation and policy, and from a social science perspective. A general multiagent framework is established to simulate the behaviour of and interaction between multiple entities in P2P energy trading. A general evaluation index hierarchy is proposed to assess various P2P energy trading mechanisms. Finally, a residential community that is set in the context of Great Britain is studied using multiagent simulation and hierarchical evaluation methods. Both the technical and economic benefits of P2P energy trading are demonstrated.

Published: December 2021

Background: The values of biomarkers play a central role in routine clinical decision-making. Whereas the performance of different automated chemical analyzers remains unclear. To determine the performance of different platforms, we compared the consistency and accuracy between Roche Cobas 8000 and Mindray BS2000M. Methods: A total of 1869 remaining serum samples were collected. CK, LDH-1, RBP, Cys-C, IgA, IgM, and IgG were assessed using paired t-test, Passing-Bablok regression analysis, and Bland-Altman analysis according to CLSI EP5-A3. Results: There were significant differences in the average bias of all items between the two machines (P<0.001). Because the 95% confidence interval of intercept A included 0, CK, LDH-1, Cys-C and IgG did not show systematic error in Passing-Bablok regression analysis. The confidence interval of 95% of the slope B in IgM contained 1, and there was no difference in the two measurements in IgM. Except for IgA, the r values and correlation coefficient of all items were higher than 0.91, which showed that the correlation and consistency were good. The Bland-Altman analysis showed that two instruments had more than 95% of the points apart from CK, LDH-1, and IgA. Conclusions: It can be considered that the two instruments have good correlation and consistency in CK, LDH-1, RBP, Cys-C, IgM, and IgG, and the two instruments are interchangeable and can replace each other.

Published: December 2021

Long-term potentiation (LTP) is arguably the most compelling cellular model for learning and memory. While the mechanisms underlying the induction of LTP (‘learning’) are well understood, the maintenance of LTP (‘memory’) has remained contentious over the last 20 years. Here, we find that Ca2+-calmodulin-dependent kinase II (CaMKII) contributes to synaptic transmission and is required LTP maintenance. Acute inhibition of CaMKII erases LTP and transient inhibition of CaMKII enhances subsequent LTP. These findings strongly support the role of CaMKII as a molecular storage device.

CRAC channel regulator 2 A (CRACR2A) is a large Rab GTPase that is expressed abundantly in T cells and acts as a signal transmitter between T cell receptor stimulation and activation of the Ca2+-NFAT and JNK-AP1 pathways. CRACR2A has been linked to human diseases in numerous genome-wide association studies, however, to date no patient with damaging variants in CRACR2A has been identified. In this study, we describe a patient harboring biallelic variants in CRACR2A [paternal allele c.834 gaG> gaT (p.E278D) and maternal alelle c.430 Aga > Gga (p.R144G) c.898 Gag> Tag (p.E300*)], the gene encoding CRACR2A. The 33-year-old patient of East-Asian origin exhibited late onset combined immunodeficiency characterised by recurrent chest infections, panhypogammaglobulinemia and CD4+ T cell lymphopenia. In vitro exposure of patient B cells to a T-dependent stimulus resulted in normal generation of antibody-secreting cells, however the patient’s T cells showed pronounced reduction in CRACR2A protein levels and reduced proximal TCR signaling, including dampened SOCE and reduced JNK phosphorylation, that contributed to a defect in proliferation and cytokine production. Expression of individual allelic mutants in CRACR2A-deleted T cells showed that the CRACR2AE278D mutant did not affect JNK phosphorylation, but impaired SOCE which resulted in reduced cytokine production. The truncated double mutant CRACR2AR144G/E300* showed a pronounced defect in JNK phosphorylation as well as SOCE and strong impairment in cytokine production. Thus, we have identified variants in CRACR2A that led to late-stage combined immunodeficiency characterized by loss of function in T cells.
How the Concept of Performativity Travels: between People and Media / Kuidas performatiivsuse mõiste rändab: inimeste ja meedia vahel

Published: December 2021

Abstract: This article examines how the concepts of performance and performativity can neither be merged nor firmly distinguished. The author calls on her own practice as a video-maker and academic thinker, establishing a dialogue between the two activities. She borrows extensively from the work of a colleague, with examples from photography, considering collegiality also a form of performativity. The conceptualisation helps argue for a shift from activist to activating art.

 

Resümee: Artikkel uurib, kuidas etenduse ja performatiivsuse mõisteid ei saa ühitada ega selgelt eristada. Autor tugineb oma kogemusele videorežissööri ja akadeemilise mõtlejana, luues dialoogi nende kahe tegevuse vahel. Kolleegi fotograafia-alastest töödest lähtudes arutleb ta kolleegiaalsuse kui performatiivsuse ühe vormi üle. See kontseptsioon viib tõdemuseni, et kunsti kui aktivismi juurest tuleks liikuda aktiveeriva kunsti juurde.
The posttraumatic stress interview for children (KID-PIN): development and validation of a semi-structured interview of PTSD symptoms among displaced children in the Middle East
Authors: Ibrahim Hawkar , Catani Claudia , Neuner Frank
Published: December 2021

Background

In populations affected by mass disaster such as armed conflict and displacement, children are at risk of developing mental ill-health, in particular post-traumatic stress disorder (PTSD). Valid and reliable screening instruments are needed to assess the severity of PTSD symptoms among children and to identify individuals in need of treatment.

Method

In the context of an ongoing war in the Middle East, we developed the KID-PIN as a semi-structured interview for PTSD symptoms that can be administered by trained paraprofessionals. To achieve a culturally and contextually appropriate instrument, the development was based on open-ended interviews with affected children and involved both local and international experts. Using the KID-PIN and instruments for constructs associated with PTSD, 332 Iraqi and Syrian displaced children were interviewed. A subset of the sample (n = 86) participated in validation interviews based on experts applying the Clinician-Administered PTSD Scale for DSM-5—Child/Adolescent Version (CAPS-CA-5).

Results

The KID-PIN demonstrated excellent internal consistency (Cronbach’s alpha = 0.94) with good convergent validity. Confirmatory factor analyses of the KID-PIN showed an acceptable fit with the DSM-5 and other common models; the best fit was reached with the Hybrid model. Receiver operating characteristic analyses indicated that the cut-off score of 28 or higher on the KID-PIN is the optimum cut-off for a probable PTSD diagnosis.

Conclusion

The utility of the newly developed KID-PIN as a screening instrument for PTSD in children is supported by the measure’s high internal consistency and good convergent and structural validity, as well as its diagnostic accuracy.
Morpho-physiological effects of environmental stress on yield and quality of sweet corn varieties (Zea mays L.)
Authors: Tas Timucin , Mutlu Arzu
Published: December 2021

Sweet corn is cultivated in different climatic regions of the world, and consumed either fresh or processed. Morpho-physiological effects of environmental stress on yield, yield components and quality of some sweet corn varieties were investigated in field experiments conducted at Southeastern Anatolia Region of Turkey during 2019 and 2020 growing seasons. The experimental lay out was randomized blocks with three replicates. Eight candidates and two control sweet corn varieties classified as moderate maturity (FAO 650–700) were used in field experiment. Mean values of pollen fertility rate (PFR, %), total soluble solids (TSS, °Brix), abscisic acid (ABA, nmol/g DW), ear length (EL, cm), plant height (PH, cm), number of grains per cob (CGN, grain) and fresh cob yield (FCY, t ha−1) were significantly different between years and sweet corn varieties. The PFR, TSS, ABA, EL, PH, CGN and FCY ranged from 40.29–67.65%, 13.24–20.09 °brix, 7.74–21.04 nmol/g DW, 9.69–15.98 cm, 97.80–171.34 cm, 289.15–420.33 grain and 4.15–10.23 t ha−1 respectively. The FCY, yield components and PFR values in the second year that had a higher temperature and lower relative humidity were lower compared to the first year, while ABA and TSS values were higher in the second year. Statistically significant correlations were recorded between the parameters investigated except FCY and TSS. The FCY and other parameters of sweet corn varieties, which produced high ABA phytohormone, were high, and the ABA hormone significantly contributed to plant growth under stress conditions. The results revealed that the PFR physiological parameter and ABA hormone in the plants provide important information about stress level and stress tolerance level of the cultivars, respectively. Despite adverse environmental stress conditions, the FCY of ŞADA-18.7 variety, one of the candidate varieties, was higher than that of the control and the mean value of the experiment.
Variation in global distribution, population structures, and demographic history for fourTrichiuruscutlassfishes

Background

Species-specific information on distribution and demographic patterns provides important implications for conservation and fisheries management. However, such information is often lacking for morphologically-similar species, which may lead to biases in the assessments of these species and even decrease effort towards sustainable management. Here, we aimed to uncover the distribution range, population structure and demographic history for four exploitedTrichiuruscutlassfishes using genetics. These cutlassfishes contribute substantial global fisheries catch, with a high proportion of catch harvested from the NW Pacific.

Methods

We chose the widely available mitochondrial 16S ribosomal RNA (16S) as the genetic marker for cutlassfishes. We compiled the 16S sequence data from both the GenBank and a survey of trawler catch samples along the NW Pacific coasts 22–39°N. Genealogical relationships within each species was visualized with haplotype networks and potential population differentiations were further evaluated with AMOVA. Demographic histories were estimated using neutrality test, mismatch analysis, and the Bayesian skyline plot. The reconstructed phylogenetic trees were used to delimit and estimate the divergence time of species and included populations.

Results

In each of two cosmopolitan species,T. lepturusandT. nanhaiensis, we observed distinct populations along the coasts of warm oceans; such population differentiation might result from historical geographic barriers in the Pleistocene. In the NW Pacific, fourTrichiurusspecies vary in their distribution habitats, which reflect differential ecological niches among these species. The small-sizedT. brevisare primarily found in nearshore habitats; the warm-affiliatedT. nanhaiensisare present along the path of the Kuroshio Current; the cold-affiliatedT. japonicusspatially diverged from the widely-distributedT. lepturus, with the latter mainly occupy in warmer regions. Despite these differences, a single well-mixing fish stock, thus one management unit, was identified in each of the four species, presumably due to expansion of their population sizes predated the Last Glacial Maximum and a lack of distribution barrier. The most dominantT. japonicus, which have at least one magnitude higher effective population size than the others, show a unique abrupt size expansion event at 75 to 50-kilo years ago when the low sea level occurred during the ice age.

Main conclusions

The demographic history revealed by our genetic analyses advances understanding of the current distribution and population structure for these congeneric species. Moreover, the uncovered population structure provides insight into the assessment and management of these species. Such information complements contemporary knowledge about these species and enables us to forecast their ability to resist future environmental and anthropogenic disturbances.

The purpose of the work is to consider the relationship between the current economic situation and the pace of development of coronavirus infection, which has had a direct impact on various spheres of society. Doctors around the world are calling on citizens to be vaccinated, because only the formation of the so-called global immunity will allow to resist the further development of the pandemic.

The situation with the wave-like development of morbidity, which causes the announcement of more and more restrictive measures and, as a result, a decrease in the economic activity of the population, also testifies in favor of universal vaccination. The prospects for future economic development at such rates of infecting the population in various countries are rather vague, so the promotion of vaccination is gaining momentum. However, the choice of a particular vaccine often becomes a difficult issue for most citizens, since all vaccines were developed in a fairly short time, their adaptation took place at an ultra-high pace, and many citizens question the side effects of vaccines.

It seems to us that the problem can be solved by the common "elimination of illiteracy" in the field of vaccination against coronavirus and formation of a collective understanding of the need to join the vaccinated on the basis of explanatory work among potential patients of vaccination offices, based on scientific facts and submitted in a popular scientific form.
