Published: April 2023

Abstract. Since the major tsunami that occurred in 2004, many studies have dealt with the evacuations, hazard mapping and awareness-actions, rather than on the perceived tsunami risk nor on alert perceptions declared locally by the population. In this study, we analyzed a sample of 750 answers to a face-to-face questionnaire, gathered from residents or workers in 5 densely-urbanized municipalities (e.g., Bandol, Bastia, Cannes, Six-Fours-Les-Plages, Sanary-sur-Mer), likely to be hit by a tsunami and bordering the French Mediterranean basin. Results first confirmed the tendency to underestimate the tsunami risk, as only 15.6 % identify tsunami as a risk. However, 48.7 % declare they should take protective actions if they feel ground-shaking on the seafront, and even 65.3 % if they also see a anormal sea movement. In contrast, the efficacy of alerting tools and the actors who can alert them are overestimated, as 44.7 % of the respondents think they should be alerted by sirens and 11.7 % by SMS, while such tools are not systematically present and rarely cover tsunami evacuation zones. And only 29.4 % correctly identify the official alert senders: mayors or prefectures. In contrast, 55.7 % declare they go high ground if they receive such instructions in one Alert SMS. The age, gender, residency status or location of the respondents explain a few differences in the collected data. However, relationships between tsunami risk and alert perceptions appear statistically not corelated. All the knowledge produced in this study finally might help the municipalities further develop awareness-actions and information on the tsunami, and inform what strategy they may apply in a short future to better increase the tsunami preparedness.

Abstract. The oxygen (𝛥17O) and nitrogen (𝛿15N) isotopic compositions of atmospheric nitrate (NO3-) are widely used as tracers of its formation pathways, precursor (nitrogen oxides NOx = nitric oxide NO + nitrogen NO2) emission sources, and physico-chemical processing. However, the critical lack of observations on the multi-isotopic composition of NO2 maintains significant uncertainties regarding the links between the isotopic composition of NOx and NO3-, which may bias estimates of the NO3- formation processes and the distribution of sources. We report here on the first simultaneous atmospheric observations of 𝛥17O and 𝛿15N in NO2 and NO3-. The measurements were carried out at sub-daily (ca. 3 h) resolution over two non-consecutive days in an Alpine city in February 2021. Important diurnal variabilities are observed in both NO2 and NO3- multi-isotopic composition. 𝛥17O of NO2 and NO3- range from 19.6 to 40.8 ‰ and 18.7 to 26 ‰, respectively. During both daytime and nighttime, the variability of 𝛥17O(NO2) is mainly driven by the oxidation of NO by ozone, with a substantial contribution from peroxy radicals in the morning. NO3- local mass balance equations, constrained by observed 𝛥17O(NO2), suggest that during the first day of sampling NO3- was formed locally from the oxidation of NO2 by hydroxyl radicals during the day, and via heterogeneous hydrolysis of dinitrogen pentoxide during the night. For the second day, calculated and observed 𝛥17O(NO3-) do not match, particularly daytime values. The effects on 𝛥17O(NO3-) of a Saharan dust event that occurred during the second day and winter boundary layer dynamics are discussed. 𝛿15N of NO2 and NO3- ranged from -10.0 to 19.7 ‰ and -4.2 to 14.8 ‰, respectively. Consistent with theoretical predictions of N isotope fractionation, the important variability of 𝛿15N(NO2) is explained by significant post-emission equilibrium N fractionation. After accounting for this effect, vehicle exhaust is found to be the primary source of NOx emissions at the sampling site. 𝛿15N(NO3-) is closely linked to 𝛿15N(NO2) variability, which bring further evidence of fast and local processing, but uncertainties on current N fractionation factors during NO2 to NO3- conversion are underscored. Overall, this detailed investigation highlights the potential and the necessity to use 𝛥17O and 𝛿15N in NO2 and NO3- to trace quantitatively the sources and formation chemistry of NO3-, particularly in urban environments in winter.
Modeling saline fluid flow through subglacial ice-walled channels and the impact of density on fluid flux

Published: April 2023

Abstract. Subglacial hydrological systems have impacts on ice dynamics, as well as, nutrient and sediment transport. There has been extensive effort to understand the dynamics of subglacial drainage through numerical modeling. These models, however, have focused on freshwater in warm ice and neglected the consideration of fluid chemistry such as salts. Saline fluid can exist in cold-based glacier systems where freshwater cannot and understanding the routing of saline fluid is important for understanding geochemical and microbiological processes in these saline cryospheric habitats. A better characterization of such terrestrial environments may provide insight to analogous systems on other planetary bodies. We present a model of channelized drainage from a hypersaline subglacial lake and highlight the impact of salinity on melt rates in an ice-walled channel. The model results show that channel walls grow more quickly when fluid contains higher salt concentrations which lead to higher discharge rates. We show this is due to a higher density fluid moving through a gravitational potential. This model provides a framework to assess the impact of fluid chemistry and properties on the spatial and temporal variation of fluid flux.

Abstract. The south-central interior of Andalusia experiences intricate precipitation patterns as a result of its semi-arid Mediterranean climate and the impact of Saharan dust and human-made pollutants. The primary aim of this study is to monitor the inter-relations between various factors, such as aerosols, clouds, and meteorological variables, and precipitation systems in Granada using ground-based remote sensing and in situ instruments including microwave radiometer, ceilometer, cloud radar, nephelometer, and weather station. The objective is to identify potential properties of precipitation in the region and in that way improve precipitation forecasting. Over an 11-year period, we detected rain events using a physical retrieval method that employed microwave radiometer measurements. A composite analysis was applied to them to construct a climatology of the temporal evolution of precipitation. It was found that convective rain is the dominant precipitation type in Granada, accounting for 68 % of the rain events. The height of the cloud base is mainly distributed at an altitude of 2 to 7 km. Integrated water vapor (IWV) and integrated cloud liquid water (ILW) increase rapidly before the onset of rain. Aerosol scattering at surface level and hence the aerosol concentration is reduced during rain, and the predominant mean size distribution of aerosol particles before, during, and after rain is almost the same. A meteorological environment favorable for virga formation is observed in Granada. The surface weather station detected rainfall later than the microwave radiometer, indicating virga according to ceilometer and cloud radar data. We used rain-day events identified by weather station data to determine precipitation intensity classes and found that light rain is the main precipitation intensity class in Granada, accounting for 72 % of the rain-day events. This can be a result of the high tropospheric temperature induced by the Andalusian climate and the reduction of cloud droplet size by the high availability of aerosol particles in the urban atmosphere. This study provides evidence that aerosols, clouds, and meteorological variables have a combined impact on precipitation which can be considered for water resource management and improving rain forecasting accuracy.
Spatiotemporal snow water storage uncertainty in the midlatitude American Cordillera

Published: April 2023

Abstract. This work quantifies the uncertainty of accumulation-season peak snow water storage in the portions of the midlatitude American Cordillera where snow is a dominant driver of hydrology. This is accomplished through intercomparison of commonly used global and regional products over the Western U.S. (WUS) and Andes domains, which have similar hydrometeorology but are disparate with respect to the amount of available in situ information. The recently developed WUS Snow Reanalysis (WUS-SR) and Andes Snow Reanalysis (Andes-SR) datasets, which have been extensively verified against in situ measurements, are used as baseline reference datasets in the intercomparison. Relative to WUS-SR climatological peak SWE storage (269 km3), high- and moderate-resolution products (i.e. those with resolutions less than ~10 km) are in much better agreement (284 ± 14 km3; overestimated by 6 %) compared to low-resolution products (127 km3 ± 54 km3; underestimated by 53 %). In comparison to the Andes-SR peak snow storage (29 km3), all other products show large uncertainty and bias (19 km3 ± 16 km3; underestimated by 34 %). Examination of spatial patterns related to orographic effects, showed that only the high- to moderate-resolution SNODAS and UA products show comparable estimates of windward-leeward SWE patterns over a subdomain (Sierra Nevada) of the WUS. Coarser products distribute too much snow on the leeward side in both the Sierra Nevada and Andes, missing orographic-rainshadow patterns that have important hydrological implications. The uncertainty of peak seasonal snow storage is primarily explained by precipitation uncertainty in both the WUS (R2 = 0.55) and Andes (R2 = 0.84). Despite using similar forcing inputs, snow storage diverges significantly within the ERA5 (i.e. ERA5 vs. ERA5-Land) products and the GLDAS (modeled with Noah, VIC, and Catchment model) products due to resolution-induced elevation differences and/or differing model process representation related to rain–snow partitioning and accumulation-season snowmelt generation. The availability and use of in situ precipitation and snow measurements (i.e., in WUS) in some products adds value by reducing snow storage uncertainty, however where such data are limited, i.e. in the Andes, significant biases and uncertainty exist.

Abstract. The inflow of warm and saline Atlantic water to the Arctic Mediterranean (Nordic Seas and Arctic Ocean) between Iceland and the Faroes (IF-inflow) is the strongest Atlantic inflow branch, in terms of volume transport, and associated with a large transport of heat towards the Arctic. The IF-inflow is monitored on a section east of the Iceland-Faroe Ridge (IFR) by use of Sea Level Anomaly (SLA) data from satellite altimetry, a method that has been calibrated by in situ observations gathered over two decades. Monthly averaged surface velocity anomalies calculated from SLA data were strongly correlated with anomalies measured by moored Acoustic Doppler Current Profilers (ADCPs) with consistently higher correlations when using the reprocessed SLA data released in December 2021 rather than the earlier version. In contrast to the earlier version, the reprocessed data also had the correct conversion factor required by geostrophy. Our results show that the IF-inflow crosses the IFR in two separate branches. The Icelandic branch is a jet over the Icelandic slope with average surface speed exceeding 20 cm s−1, but it is narrow and shallow with an average volume transport less than 1 Sv (106 m3 s−1). Most of the Atlantic water crosses the IFR close to its southernmost end in the Faroese branch. Between these two branches, water from the Icelandic branch turns back onto the ridge in a retroflection with a recirculation over the northernmost bank on the IFR. Combining multi-sensor in situ observations with satellite SLA data, monthly mean volume transport of the IF-inflow has been determined from January 1993 to December 2021. The IF-inflow is part of the Atlantic Meridional Overturning Circulation (AMOC), which is expected to weaken under continued global warming. Our results show no weakening of the IF-inflow. Annually averaged volume transport of Atlantic water through the monitoring section had a statistically significant (95 % confidence level) increasing trend of (0.12 ± 0.10) Sv per decade. Combined with increasing temperature, this caused an increase of 13 % in the heat transport, relative to 0 °C, towards the Arctic of the IF-inflow over the 29 years of monitoring. The near-bottom layer over most of the IFR is dominated by cold water of Arctic origin that may contribute to the overflow across the ridge. Our observations confirm a dynamic link between the overflow and the Atlantic water flow above. The results also provide support for a previously posed hypothesis that this link may explain the difficulties in reproducing observed transport variations of the IF-inflow in numerical ocean models, with consequences for its predictability under climate change.
A control volume finite-element model for predicting the morphology of cohesive-frictional debris flow deposits

Published: April 2023

Abstract. To predict the morphology of debris flow deposits, a control volume finite-element model (CVFEM) is proposed, balancing material fluxes over irregular control volumes. Locally, the magnitude of these fluxes is taken proportional to the difference between the surface slope and a critical slope, dependent on the thickness of the flow layer. For the critical slope, a Mohr–Coulomb (cohesive-frictional) constitutive relation is assumed, combining a yield stress with a friction angle. To verify the proposed framework, the CVFEM numerical algorithm is first applied to idealized geometries, for which analytical solutions are available. The Mohr–Coulomb constitutive relation is then checked against debris flow deposit profiles measured in the field. Finally, CVFEM simulations are compared with laboratory experiments for various complex geometries, including canyon–plain and canyon–valley transitions. The results demonstrate the capability of the proposed model and clarify the influence of friction angle and yield stress on deposit morphology. Features shared by the field, laboratory, and simulation results include the formation of steep snouts along lobe margins.
Probabilistic projections and past trends of sea level rise in Finland

Published: April 2023

Abstract. We explore past trends and future projections of mean sea level (MSL) at the Finnish coast, in the northeastern Baltic Sea, during the period 1901–2100. We decompose the relative MSL change into three components: regional sea level rise (SLR), postglacial land uplift, and the effect of changes in wind climate. Past trends of regional SLR can be calculated after subtracting the other two components from the MSL trends observed by tide gauges, as the land uplift rates obtained from the semi-empirical model NKG2016LU are independent of tide gauge observations. According to the results, local absolute SLR trends are close to global mean rates. To construct future projections, we combine an ensemble of global SLR projections in a probabilistic framework. In addition, we use climate model results to estimate future changes in wind climate and their effect on MSL in the semi-enclosed Baltic Sea. This yields probability distributions of MSL change for three scenarios representing different future emission pathways. Spatial variations in the MSL projections result primarily from different local land uplift rates: under the medium-emission scenario RCP4.5/SSP2-4.5, for example, the projected MSL change (5 % to 95 % range) over the 21st century varies from −28 (−54 to 24) cm in the Bothnian Bay to 31 (5 to 83) cm in the eastern Gulf of Finland.

Published: April 2023

Aggregate gradation is measured by determining the percentage of various particle sizes in an aggregate sample using a standard sieve arrangement. Gradation is usually expressed as a curve showing the percentage of each particle size on a logarithmic scale. This curve can then be used to determine the optimum mix design for a given concrete grade. The purpose of this research is to determine the effect of adjusting the gradation of the coarse aggregate of crushed clinker bricks on the strength of concrete. Clinkers bricks are bricks that have been burned at temperatures that are excessively high. The coarse aggregate grading is adjusted according to aggregate grading limits based on SNI 7656-2012, which are divided into three types of grading limits, namely upper, middle, and lower limits. A total of 60 cylindrical 150mm x 300mm concrete specimens were used for the compressive strength tests. The findings showed that adjusting the lower limit gradation produced optimum compressive strengths of 29.09 MPa, 35.08 MPa, 39.96 MPa, and 38.82 MPa, respectively, for the specified target concrete strengths of 20 MPa, 25 MPa, 30 MPa, and 35 MPa, which were higher than those of the middle and upper limit gradations. The compressive strength and density of the concrete can be significantly improved by modification of the coarse aggregate grading of the clinker bricks

Autism Spectrum Disorder and Face Identity Recognition Deficit across Ages
Authors: Song Ye
Published: April 2023

The purpose of this review was to assess the face identity recognition deficit and the developmental difference that manifested in autism spectrum disorder (ASD) compared to their typically developing (TD) peers. Based on the meta-analysis using a random-effect model of 94 studies, with 144 effect sizes, for both adult and pediatric subjects with simultaneous and delayed face identity recognition paradigms, the underperformance in ASD was significant and persistent across ages. In addition, a higher level of deficit was found in adult ASD when performing simultaneous face-matching tasks while other subgroups showed homogenous effect sizes. This suggested a dissociation between the difficulties of the two mechanisms of face recognition: face perception (perceiving identity from the face with minimal memory load required) and face memory (recall of identity from the face that requires memory load), which was only shown in adults but not in children. The result indicated the possibility of using face identity recognition deficit as a diagnostic trait for ASD.

As a promising solid-state sensor at room temperature, diamond magnetometers based on nitrogen-vacancy (NV) centers have been developed tremendously in recent years. Many studies have demonstrated its potential for achieving high spatial resolution and sensitivity. However, the temperature dependence of the zero-field splitting D of NV centers poses an enormous challenge for the application of diamond magnetometry, since it is difficult to avoid temperature drift in most application scenarios. Here, we demonstrate a type of temperature-robust diamond magnetometry based on the double-transition method. By utilizing both transitions between \begin{document}$|m_{\rm{s}}=0\rangle$\end{document} and \begin{document}$|m_{\rm{s}}=\pm1\rangle$\end{document} sublevels with incomplete degeneracy of the \begin{document}$|m_{\rm{s}}=\pm1\rangle$\end{document}states, the impacts of D variations induced by temperature drift can be counteracted. The drift of magnetic field measurement result has been reduced by approximately 7-fold. With further improvements, the temperature-robust diamond magnetometry has the potential to be applied in biomagnetism and space science research.

In China, ESG funds are still in the early stage of development, and how to improve their performance level has become an urgent problem. Based on 26 ESG funds in 2018–2021, we use the DEA-Malmquist productivity index method to evaluate the performance of ESG funds at two levels, static and dynamic, and apply the fsQCA approach to explore the performance improvement path of ESG funds. Overall, ESG funds perform well, but there are significant differences among them. The total factor productivity of ESG funds shows a decreasing trend during the study period. There are three paths to improve the performance of ESG funds. The 1st path is to maintain a low concentration of holdings and reduce the frequency of fund position adjustments based on increasing fund size. The 2nd path is to diversify into stocks with high ESG scores based on increasing fund size. The 3rd path is to hold stocks with high ESG scores for a long time based on increasing fund size. Concerning the results of the empirical analysis, it proposes to improve the ESG rating system, broaden the market scale of ESG funds at a steady gait, and gradually optimize fund managers’ investment strategies.

O Brasil está em franco processo de envelhecimento, tendo já atravessado as etapas iniciais do processo de transição epidemiológica ou demográfica e, no caso de algumas áreas localizadas de regiões metropolitanas mais desenvolvidas, atingido seu estágio final. A Constituição Federal de 1988 instituiu a dignidade da pessoa humana como um dos fundamentos da República Federativa do Brasil e, ao tratá-la desse modo, o constituinte, além de atribuir dignidade às pessoas, impôs ao poder público o dever de respeito, proteção e promoção dos meios necessários à realização de uma vida digna, incluindo-se as pessoas idosas. Diante desse novo cenário de inversão da pirâmide etária, e em um contexto de predominância dos direitos humanos, a promoção da dignidade da pessoa humana do idoso se afigura indispensável. Nessa perspectiva, através da utilização do método de abordagem hipotético dedutivo, dos métodos de procedimentos tipológico, funcionalista e sistêmico, e de uma interpelação teórico-descritiva, com a realização de pesquisa bibliográfica, análise da normatização brasileira e consulta a diplomas internacionais, buscar-se-á, de forma geral, analisar a gestão da proteção integral do idoso no município de São José do Egito/PE e, de forma específica, verificar de que forma a proteção integral do idoso funciona como um instrumento de garantia da dignidade da pessoa humana, e investigar as políticas públicas de atenção ao idoso no município de São José do Egito/PE.

Probability Logics for Reasoning About Quantum Observations
Authors: Stepic Angelina Ilic
Published: April 2023

In this paper, we present two families of probability logics (denoted QLP and QLPORT ) suitable for reasoning about quantum observations. Assume that a means “O = a”. The notion of measuring of an observable O can be expressed using formulas of the form ??a which intuitively means “if we measure O we obtain a”. In that way, instead of non-distributive structures (i.e., non-distributive lattices), it is possible to relay on classical logic extended with the corresponding modal laws for the modal logic B.

We consider probability formulas of the form CSz1,?1;...;zm,?m??a related to an observable O and a possible world (vector) w: if a is an eigenvalue of O, w1, . . . , wm form a base of a closed subspace of the considered Hilbert space which corresponds to eigenvalue a, and if w is a linear combination of the basis vectors such that w = c1·w1+. . .+cm·wm for some ci ? C, then ?c1 - z1? = ?1, . . . , ?cm - zm? = ?m, and the probability of obtaining a while measuring O in the state w is equal to Sm i=1?ci?2.

Formulas are interpreted in reflexive and symmetric Kripke models equipped with probability distributions over families of subsets of possible worlds that are orthocomplemented lattices, while for QLPORT also satisfy ortomodularity. We give infinitary axiomatizations, prove the corresponding soundness and strong completeness theorems, and also decidability for QLP-logics.

Published: April 2023

The encounter between people of Ethnic Chinese with the church and Christianity has been going on for a long time. However, this long-standing encounter did not accommodate the good values contained in Chinese tradition and culture into the Church. Chinese community-based Christian churches only accommodate Mandarin. Traditions such as respect for parents and ancestors are not accommodated in Christian practice. This is due to the concern that such a tradition will contaminate the faith of the congregation. This study aims to examine the Chinese-Christian relationship and try to find opportunities to harmonize the two. This study uses a qualitative descriptive method with a literature study technique. As for the results of his research: 1) The finding of conformity to a certain degree of the practice of respecting parents and ancestors with the texts in the Old and New Testaments. This conformity can be found by finding the good side of Chinese tradition and culture; 2) Such conformity and respect can be an entry point for the Gospel of Christ.AbstrakPerjumpaan antara orang-orang dari Etnis Tionghoa dengan gereja dan Kristen telah berlangsung sejak lama. Namun perjumpaan yang telah berlangsung lama tersebut tidak membuat terakomodasinya nilai-nilai baik yang terdapat dalam tradisi dan budaya Tionghoa ke dalam Gereja. Gereja-gereja Kristen berbasis masyarakat Tionghoa hanya mengakomodasi Bahasa Mandarin. Tradisi seperti penghormatan terhadap orang tua dan leluhur tidak terakomodasi dalam praktik Kekristenan. Hal ini disebabkan oleh kekhawatiran bahwa tradisi semacam itu akan mengontaminasi iman jemaat. Penelitian ini bertujuan untuk menelaah hubungan Tionghoa-Kristen dan berusaha menemukan peluang mengharmoniskan keduanya. Penelitian ini menggunakan metode deskriptif kualitatif dengan teknik studi literatur. Ada pun hasil penelitiannya: 1) Ditemukannya kesesuaian dalam derajat tertentu praktik penghormatan orang tua dan leluhur dengan teks-teks dalam Perjanjian Lama dan Perjanjian Baru. Kesesuaian itu dapat dijumpai dengan menemukan sisi baik dari tradisi dan budaya Tionghoa; 2) Kesesuaian  dan penghormatan tersebut dapat menjadi celah masuknya Injil Kristus.

Published: April 2023

Growing changes increase the complexity of managing the development of Russian regions and require the refinement of strategic planning tools. Therefore, it is important to study the spatial development within the boundaries of a certain set of regions and discuss the results of obtained assessments. The present research presents the analysis of the topological characteristics of the district’s spatial development on the example of the NWFD regions. The obtained results and the conclusions formed on their basis allow us to determine the limitations in the development of the NWFD regions and suggest possible ways to solve discovered problems. The results of the study indicate that the NWFD is characterized by a large differentiation in the level of social and economic development, reduction in economic activity, accompanied by negative trends in the social sector. Nevertheless, there are foundations for the formation of development prospects and overcoming the negative factors.
BALANCING THE FACTORS OF COMPETITIVE ATTRACTIVENESS OF THE REGIONS FOR HARMONIZATION OF SOCIAL AND ECONOMIC SPHERES AND THE ACTIVATION OF DEVELOPMENT SYNERGY
Authors:   Institute for Regional Economic Studies Russian Academy of Sciences, Grinchel Boris M.
Published: April 2023

The paper considers the methodology and indicators for balancing the socio-economic development of regions. It is proposed to consider the balance in the context of generalizing indicators of the competitive attractiveness of the territorial space for residents, enterprises and business structures, tourists and other active and attracted consumers of the territory. Balance means the minimization of imbalances of the region between the assessments of competitive attractiveness by four factors: economy, innovation, quality of life and human potential. The proposed method and indicators are tested on real calculations for the regions of Russia and in-depth for eleven regions of the North-Western Federal District based on statistical data of the 2020. The analysis of the balance of development is carried out in two aspects: between the competitive attractiveness of individual factors and their integral assessment and between the level of development of relevant factors in their interrelation. The second aspect of the analysis is considered in detail for the regions of the North-Western Federal District. The possibilities and informativeness of assessments of the balance of competitive attractiveness factors for the analysis of the features of territorial space and strategic management are shown.

A SYSTEM FOR REGULATING THE COMMON COMPONENT OF THE INPUT VOLTAGE IN A RECEIVER
Authors: GRIGORYAN M.T. , SAHAKYAN A.S.
Published: April 2023

A method of building a system for adjusting the common mode variation of the input signal of the receiver in SERDES systems is presented. A negative feedback connection between the current source with constant conductivity and the matrix of series resistors is introduced, which allows to decrease the variation of common mode voltage level of the continious time linear equalizer circuit. By providing a high voltage level, the current source transistors operate in the saturation mode and provide a low gain in the low
frequency range. The simulation results show that in the case of using the proposed method, the amplification of the system at low frequencies decrease by approximately 76% due to the reduction of the amplification factor at working frequencies by about 4.8%.
Ebeveynlerin Çocukluk Dönemi Aşıları İle İlgili Bilgi, Tutum Ve Davranışlarının İncelenmesi
Authors: ÇAY Betül , GÖL İlknur
Published: April 2023

Amaç: Bu çalışmada, ebeveynlerin çocukluk dönemi aşılarıyla ilgili bilgi, tutum ve davranışlarını belirlemek amaçlanmıştır.

Yöntem: Kesitsel tipte tanımlayıcı çalışmanın örneklemini; Batı Karadeniz'de bir ilçe merkezinde bulunan iki aile sağlığı merkezine Kasım 2020-Şubat 2021 tarihleri arasında başvuran 0-6 yaş çocuğu bulunan 110 ebeveyn oluşturmuştur. Verilerin toplanmasında, ebeveynlerin sosyodemografik özelliklerini, aşılar ile ilgili bilgi, tutum ve davranışlarını belirleyen bir anket formu ve Aşıya ilişkin Tutumlar Ölçeği kullanılmıştır. Verilerin değerlendirilmesinde, tanımlayıcı istatistiklerin yanı sıra gruplar arası karşılaştırmada t testi ve tek yönlü varyans analizi kullanılmıştır.

Bulgular: Ebeveynlerin %85.5’inin aşıların gerekli olduğunu düşündüğü, % 90.9’unun çocuklarının aşılarını düzenli olarak yaptırdığı ve %29.1’inin en az bir özel aşı yaptırdığı belirlenmiştir. Rutin aşı takviminde yer alan herhangi bir aşı hakkında bilgi sahibi olmayan ebeveynlerin oranı %10.9’dur. Ebeveynlerin %74.5’i aşıların yan etkisi olduğunu ve %8.5’i otizmi, %6.1’i de kısırlığı aşı yan etkisi olarak düşünmektedir. Ebeveynlerin, Aşıya İlişkin Tutumlar Ölçeği puan ortalamaları 50.43±9.00 olup aşılara ilişkin tutumları orta düzeydedir. İl merkezinde yaşayan, gelirinin giderinden fazla olduğunu ifade eden, aşıların gerekli olduğunu düşünen ve aşılar hakkındaki bilgiyi sağlık profesyonelinden alan ebeveynlerin Aşıya ilişkin tutumlar ölçeği puan ortalamalarının daha yüksek olduğu belirlenmiştir (p≤0.05).

Sonuç: Çalışmada ebeveynlerin önemli bir bölümünün çocuklarının aşılarını düzenli olarak yaptırdığı belirlenmekle birlikte aşının gerekli olmadığını düşünen, aşıların yan etkileri konusunda yanlış bilgiye sahip olan ve rutin uygulanan aşılar hakkında bilgi sahibi olmayan ebeveynlerinde olduğu görülmüştür. Ebeveynlerin aşılara yönelik tutumlarının olumlu yönde değişmesi için aşılar hakkındaki bilgi gereksinimlerinin belirlenmesi, aşılar ve aşılama programları hakkında doğru ve güvenilir bilgilerin sağlanması önerilebilir.

Authors: MOUSTAFİD Amine
Published: April 2023

In this paper we set-valued analyze the problem of asymptotic stabilizing the tumor size. A mathematical model of exponential tumor growing caused by carcinogenic substance is considered, with chemotherapy, immunotherapy, and radiotherapy effects. We control the model to be viable in therapeutic domains, and reverse the exponential growing of the tumor size. The obtained controls derive from the derivative cone of therapeutic domains as solution of minimizing problem.
