Characters of Ancient Architectural Orders and their Mannerist Interpretation in Dietterlin’s Book from 1598
Authors: Mako Vladimir
Published: March 2021

The aim of this paper is to explore a particular metaphorical pictorial language used by German mannerist painter Wendel Dietterlin in his book on architecture at the end of the sixteenth century. It was formed through personal imaginary interpretation of the Vitruvian notion regarding personal characters of the five ancient architectural Orders. In that context it has all aspects of the mannerist approach in inventing metaphorical meanings by combining ancient, mediaeval, and contemporary narratives. However, in that process Dietterlin unavoidably refers to cultural and social aspects of his time, particularly when reflecting on the issue of the invention of the ‘new [German] architecture’. By this, Dietterlin enters the group of the majority of German sixteenth and seventeenth century authors on architecture emphasizing one particular prerogative in their writings: to merge the ancient roots with the longing for a coherent German cultural identity. However, it seems that in the process of narration, used to ‘invent’ new forms of architectural expression, Dietterlin refers also on particularities related to the historical development of mankind in a personal manner.

Published: March 2021

India currently represents 17% of the world’s diabetes burden, with an estimated 77 million cases in 2019, a figure expected to almost double to 134 million by 2025. Currently, one in every four persons under 25 has adult-onset diabetes, a condition more usually seen in 40–50 year old people. A hospital-based cross-sectional study conducted among diabetes type 2 patients in a rural field practice area of the A.J. Institute of Medical Sciences & Research Centre, Mangalore, Karnataka. Medication adherence and factors associated with non-adherence to medication were determined using self-structured validated questionnaire. A total of 206 patients with type 2 diabetes were recruited. In the present study 49% of the patients were found to be having poor medication adherence, while 50.9% were found to be with good adherence. However, none of the patients showed perfect adherence. A significant association was observed between medication adherence and age of patients, their gender, information about the disease, family support, personal motivation, literacy status and cost of treatment. Keywords: medication adherence, type 2 diabetes mellitus, self-care practices, prevalence

A Note on Full and Complete Binary Planar Graphs
Authors: Casinillo Emily L , Casinillo Leomarich F
Published: March 2021

Let G=(V(G), E(G)) be a connected graph where V(G) is a finite nonempty set called vertex-set of G, and  E(G) is a set of unordered pairs {u, v} of distinct elements from  V(G) called the edge-set of G. If  is a connected acyclic graph or a connected graph with no cycles, then it is called a tree graph. A binary tree Tl with l levels is complete if all levels except possibly the last are completely full, and the last level has all its nodes to the left side. If we form a path on each level of a full and complete binary tree, then the graph is now called full and complete binary planar graph and it is denoted as Bn, where n is the level of the graph. This paper introduced a new planar graph which is derived from binary tree graphs. In addition, a combinatorial formula for counting its vertices, faces, and edges that depends on the level of the graph was developed.

Vietnam’s Healthcare System Decentralization: how well does it respond to global health crises such as Covid-19 pandemic?
Authors: AISDL
Published: March 2021

This article discussed Vietnam’s ongoing efforts to decentralize the health system and its fitness to respond to global health crises as presented through the Covid-19 pandemic. We used a general review and expert’s perspective to explore the topic. We found that the healthcare system in Vietnam continued to decentralize from a pyramid to a wheel model. This system shifts away from a stratified technical hierarchy of higher- and lower-level health units (pyramid model) to a system in which quality healthcare is equally expected among all health units (wheel model). This decentralization has delivered more quality healthcare facilities, greater freedom for patients to choose services at any level, a more competitive environment among hospitals to improve quality, and reductions in excess capacity burden at higher levels. It has also enabled the transformation from a patient-based traditional healthcare model into a patient-centered care system. However, this decentralization takes time and requires long-term political, financial commitment, and a working partnership among key stakeholders. This perspective provides Vietnam’s experience of the decentralization of the healthcare system that may be considered as a useful example for other countries to strategically think of and to shape their future system within their own socio-political context.

Policy and communication responses to COVID-19 can benefit from better understanding of people's baseline and resulting beliefs, behaviors, and norms. From July 2020 to March 2021, we fielded a global survey on these topics in 67 countries yielding over 2.0 million responses. This paper provides an overview of the motivation behind the survey design, details the sampling and weighting designed to make the results representative of populations of interest and presents some insights learned from the survey. Several studies have already used the survey data to analyze risk perception, attitudes towards mask wearing and other preventative behaviors, as well as trust in information sources across communities worldwide. This resource can open new areas of inquiry in public health, communication, and economic policy by leveraging one of the first ever large-scale, rich survey data on beliefs, behaviors, and norms during a global pandemic in new and innovative ways.
The Principle of Certainty
Authors: Yasin Muhammad
Published: March 2021

It is possible to prove the principle of certainty in a different way from the theory of relativity, de Broglie particle wave duality, the principle of uncertainty. The principle of certainty is the formula for measuring the position and momentum of a particle at the same time. If the theory of relativity, the principle of uncertainty is correct, then the principle of certainty must be considered correct. Because it is possible to prove the principle of certainty from the principle of uncertainty, it is also possible to prove the principle of certainty from the theory of special relativity. Again the idea of the principle of certainty comes from the de Broglie particle wave duality principle. Max Planck's radiation formula can be proved from the principle of certainty.

Which is known as the principle of certainty
Seven Steps Toward More Transparency in Statistical Practice

We argue that statistical practice in the social and behavioral sciences benefits from transparency, a fair acknowledgement of uncertainty, and openness to alternative interpretations. To promote such a practice, we recommend seven concrete statistical procedures: (1) visualizing data; (2) quantifying inferential uncertainty; (3) assessing data preprocessing choices; (4) reporting multiple models; (5) involving multiple analysts; (6) interpreting results modestly; and (7) sharing data and code. We discuss their benefits and limitations, and provide guidelines for adoption. Each of the seven procedures finds inspiration in Merton's ethos of science as reflected in the norms of communalism, universalism, disinterestedness, and organized skepticism. We believe that these ethical considerations --and their statistical consequences-- establish common ground among data analysts, despite continuing disagreements about the foundations of statistical inference.
Suggestions for improving the investigation of gesture in aphasia
Authors: Stark Brielle C , Clough Sharice , Duff Melissa
Published: March 2021

Purpose: When we speak, we gesture, and indeed, persons living with aphasia gesture more frequently. The reason(s) for this is still being investigated, spurring an increase in the number of studies of gesture usage by persons living with aphasia. As the number of studies increase, so too does the need for a shared set of standards and best practices for gesture research in aphasia. Here, we offer some considerations regarding best practices for future work involving gesture in persons living with aphasia. Methods & Results: First, we briefly review the importance and use of gesture in persons living with aphasia. Then, we explore several different design and methodological considerations for gesture research specific to persons living with aphasia, aiming to develop a transparent and reproducible evaluation of this important multimodal communication resource. Conclusions: We have proposed that it is critical to evaluate multimodal communication in a methodologically robust way in order to facilitate increased knowledge about the relationship of gesture to spoken language, cognition, and to other aspects of living with aphasia and recovery from aphasia. We conclude by postulating future directions for gesture research in aphasia.

In this study, we investigated what social, demographic and cultural factors predict and moderate the relationship between public and self stigma for help seeking. Analyses revealed a positive relationship between public and self-stigma, supporting the theory that self-stigma is internalised public stigma; no factors predicted public stigma suggesting that public stigma does not differ as a function of these different factors; that education and family income both predict self-stigma and moderate the relationship between public and self-stigma, despite personal income not predicting self-stigma or moderating the relationship between public and self-stigma.

Published: March 2021

Background: COVID-19 continues to ravage the world with economies and life significantly and negatively affected. Fortunately, there has been significant progress in the production of vaccines to stem the infection. However, with controversies and myths surrounding vaccinations, it is timely to examine individuals’ willingness to vaccinate. The present study developed and validated the Motors of COVID-19 Vaccination Acceptance Scale (MoVac-COVID19S) and assessed the acceptance of COVID-19 vaccination utilizing the cognitive model of empowerment (CME). Methods: A total of 3145 university students (mean age=20.80 years; SD=2.09) were recruited for the present study between January 5 and 16, 2021. Two MoVac-COVID19S scales (9-item and 12-item) were adapted from the MoVac-Flu Scale, an instrument developed using CME. Psychometric tests were conducted to ascertain reliability and validity properties. Results: The findings indicated that the MoVac-COVID19S had high internal consistency in both the 9-item version (ω=0.921) and 12-item version (ω=0.898). The factor structure of the MoVac-COVID19S (9-item and 12-item versions) corresponded well with CME theory. All the fit indices were satisfactory (CFI=0.984, TLI=0.971, RMSEA=0.088, SRMR=0.058) but the 9-item MoVac-COVID had better fit indices than the 12-item MoVac-COVID due to the negative wording effects existing in the 12-item MoVac-COVID19S. The scale had satisfactory known-group validity in both 9-item and 12-item versions. Conclusions: The MoVac-COVID19S has promising psychometric properties based on internal consistency, factor structure, and known-group validity.
Adaptive empathy: A model for learning empathic responses based on feedback
Authors: Hertz Uri , Shamay-Tsoory Simone
Published: March 2021

Empathy is usually deployed in social interactions. Nevertheless, common measures and examinations of empathy study this construct in isolation from the person in distress. In this paper we seek to extend the field of examination to include both empathizer and target in order to determine whether and how empathic responses are affected by feedback and learned through interaction. Building on computational approaches in feedback-based adaptations (e.g., no feedback, model-free and model-based learning), we propose a framework for understanding how empathic responses are learned based on feedback. In this framework, adaptive empathy, defined as the ability to adapt one’s empathic responses, is a central aspect of empathic skills, and can provide a new dimension to the evaluation and investigation of empathy. By extending existing neural models of empathy, we suggest that adaptive empathy may be mediated by interactions between the neural circuits associated with valuation, shared distress, observation-execution and mentalizing. Finally, we propose that adaptive empathy should be considered as a prominent facet of empathic capabilities with the potential to explain empathic behavior in health and in psychopathology.
Likely stories: Young children favor typical over atypical story events
Authors: Thorburn Rachel , Bowman-Smith Celina , Friedman Ori
Published: March 2021

Across four experiments (total N = 280) we find that children aged 2-4 show a novel bias favoring typical over atypical story events. In Experiment 1, 2-3-year-olds expected animals in a story to eat species-typical foods, even though other animals in the story ate foods atypical for their species. In Experiment 2, 2-3-year-olds successfully remembered atypical events in a story, which suggests the bias does not result from difficulty remembering these events. In Experiment 3, 3-4-year-olds chose atypical events when judging how a story would continue. But when predicting how the experimenter would continue the story, they were as likely to choose typical events. In Experiments 4A&B, children persisted in choosing typical events after having been asked to explain why earlier story events had been atypical. Overall, our findings suggest that children favor typical over atypical story events and may have difficulty disregarding or overriding the bias.
ADHD symptoms predict lower adaptation to the COVID-19 outbreak: financial decline, low adherence to preventive measures, psychological distress, and illness-related negative perceptions
Authors: Pollak Yehuda , Shoham Rachel , Dayan Haym , Seri Ortal Gabrieli , Berger Itai
Published: March 2021

Objective. The COVID-19 outbreak created numerous multidimensional stressors, to which people show different levels of vulnerability. The current paper examines whether ADHD symptoms are associated with poorer adaptation. Method. 2055 adults participated in an online survey after the first quarantine in Israel. Participants completed scales probing adaptation indicators: financial status, adherence to preventive measures, mental health, and COVID-19 related perceptions. Background measures, including the level of ADHD symptoms, were collected.Results. Adaptation indicators negatively correlated with the level of ADHD symptoms. Financial decline explained a small portion of the link between ADHD and decreased mental health; background risk-taking, anti-social, and pro-social behavior partially explained the link between ADHD and non-adherence to preventive measures; COVID-19 related perceptions also partially explained the same link.Conclusion. The current study suggests that people with ADHD are more vulnerable to the challenges created by the COVID-19 pandemic and therefore deserve special attention and care.
Evolving Networks of Human Intelligence
Authors: Savi Alexander Olof , Marsman Maarten , van der Maas Han
Published: March 2021

Twentieth century theory formation in human intelligence was dominated by factor theories; network theories will dominate the twenty first. Network theories answer a broad call for formal theories in psychological science, provide a strong approach to an idiographic science, and create an opportunity to study the developmental mechanisms of human's cognitive dynamics. Although the current century already delivered two formal stationary network theories of human intelligence—mutualism and wired intelligence—integrating dynamic mechanisms remains a serious challenge. This challenge translates into clear priorities: the identification of robust developmental phenomena, the study of the mechanisms that drive these phenomena, the integration of these mechanisms into network theories of growth, the integration of network theories from different explanatory levels, and the empirical characterization of the structure of network theories.

Published: March 2021

Background: Joint developmental trajectories of internalizing and externalizing problems show considerable heterogeneity; however, this can be parsed into a small number of meaningful subgroups. Doing so offered insights into risk factors that lead to different patterns of internalizing/externalizing trajectories. However, despite both domains of problems showing strong heritability, no study has yet considered genetic risks as predictors of joint internalizing/externalizing problem trajectories. Methods: Using parallel process latent class growth analysis, we estimated joint developmental trajectories of internalizing and externalizing difficulties assessed across ages 4 to 16 using the Strengths and Difficulties Questionnaire. Multinomial logistic regression was used to evaluate a range of demographic, perinatal, maternal mental health, and child and maternal polygenic predictors of group membership. Participants included 11049 children taking part in the Avon Longitudinal Study of Parents and Children. Polygenic data was available for 7127 children and 6836 mothers.Results: A five class model was judged optimal: Unaffected, Moderate Externalizing Symptoms, High Externalizing Symptoms, Moderate Internalizing and Externalizing Symptoms and High Internalizing and Externalizing Symptoms. Male sex, lower maternal age, maternal mental health problems, maternal smoking during pregnancy, higher child polygenic risk scores for ADHD as well as lower polygenic scores for IQ distinguished affected classes from the unaffected class.Conclusions: While affected classes could be relatively well separated from the unaffected class, phenotypic and polygenic predictors were limited in their ability to distinguish between different affected classes. Results thus add to existing evidence that internalizing and externalizing problems have mostly shared risk factors.

A Study of the Relationship between Convex Sets and Connected Sets
Authors: Malla Khem Raj
Published: March 2021

The principal objective of this research article is to explore the relationship between convex sets and connected sets. All convex sets are connected but in all cases connected sets are not convex. In the Maly theorem,let X be a Banach space, and let f:X → R be a (Fr´echet-)differentiable function. Then, for any closed convex subset C of X with nonempty interior,the image Df(C) of C by the differential Df of f is a connected subset of X∗ , where X∗ stands for thetopological dual space of X.The result does not hold true if C has an empty interior. There are counterexamples even with functions f of two variables. This article concludes that convexity cannot be replaced with the connectedness of C.
Prey Diversity of Common Leopard and Factors Affecting Human-Common Leopard Conflict in Community Forests of Arghakhanchi District Nepal
Authors: Kunwar Ashra , Koju Narayan Prasad
Published: March 2021

Conflict between human and wildlife is one of the main threats to the continued survival of many species in different parts of the world, and is also a significant threat to local human populations. As human populations expand and natural habitats shrink, people and animals are increasingly coming into conflict over living space and food. People lose their crops, livestock, property, and sometimes even their lives. Initially, with the use of structured interviews and few key informant survey, 120 households were selected for questionnaire in which 25 were from victim’s family and 95 from Sandhikharka village and the city areas using both purposive and random sampling method. Key informant interviews were also taken with officers of Division forest office and active members of community forest. Similarly, to access the prey diversity, a total of 9 infrared cameras were installed. As the objective of the research, the result was obtained based on secondary and primary data with the use of structured interviews to quantify attitudes based on 5 questions with the given scores where the scores were added together. At the end, the ANOVA test was carried outwit the variances among the control variables influencing the attitude toward leopards while assessing the overall attitudes of people with those scores. The result discusses the mean attitude of illiterate people as negative (-1.03±0.14 SE) towards leopard. Also, overall mean attitude of literate people was negative (-1.19±0.17 SE). Total 6750 images were recorded during study period among them only single event of leopard was captured in the camera trap and 72 independent prey images were captured by infrared camera. Mongoose, Wild cat, Rabbit, Porcupine and barking deer were commonly recorded. Rest of photos recorded were human movement, suggesting less prey abundance and higher human activities in study area.PCA analysis regarding factors affecting leopard human conflict suggested that the distance from water source to local people, distance from toilet to home, land use change going on in the study area, scarcity of water source to wildlife inside the forest, distance to graze livestock are major factors having positive impact on human leopard conflict.
Magic Realism as Rewriting Postcolonial Identity: A Study of Rushdie’s Midnight’s Children
Authors: Sharma Khum Prasad
Published: March 2021

Magic realism as a literary narrative mode has been used by different critics and writers in their fictional works. The majority of the magic realist narrative is set in a postcolonial context and written from the perspective of the politically oppressed group. Magic realism, by giving the marginalized and the oppressed a voice, allows them to tell their own story, to reinterpret the established version of history written from the dominant perspective and to create their own version of history. This innovative narrative mode in its opposition of the notion of absolute history emphasizes the possibility of simultaneous existence of many truths at the same time. In this paper, the researcher, in efforts to unfold conditions culturally marginalized, explores the relevance of alternative sense of reality to reinterpret the official version of colonial history in Salman Rushdie’s Midnight’s Children from the perspective of magic realism.  As a methodological approach to respond to the fiction text, magic realism endows reinterpretation and reconsideration of the official colonial history in reaffirmation of identity of the culturally marginalized people with diverse voices.

Published: March 2021

Reportamos un lazo de Costas para demodulación de un campo óptico con modulación de fase binaria (BPSK). El lazo opera en el dominio del procesamiento digital de señales (DSP) como parte de un receptor digital coherente intradino. La implementación práctica de demodulación BPSK en el dominio óptico generalmente no es factible. Por ello, empleamos técnicas basadas en la digitalización a alta velocidad del observable eléctrico post-fotodetección y el lazo de Costas en DSP actúa sobre la señal digitalizada. Elegimos este lazo por ser una estructura óptima tanto de demodulación BPSK como de sincronización de portadora. Normalmente, los lazos de Costas para demodulación BPSK operan con una portadora con frecuencia mayor que la velocidad del bit. Sin embargo, como demostramos en este trabajo, este lazo también puede operar adecuadamente para una velocidad de bit mayor que la frecuencia de portadora (detección intradina). A lo mejor de nuestro conocimiento, el lazo de Costas en DSP para demodulación BPSK intradina es reportado por primera vez en este trabajo. Para el diseño del lazo de Costas intradino nos basamos en el modelo PLL equivalente de un lazo de Costas convencional. Con fines de comparación y evaluación del desempeño, implementamos en simulación, en primer lugar, un lazo de Costas tradicional y posteriormente uno intradino. Para nuestras simulaciones empleamos señales del mundo real (datos binarios y ruido aditivo) adquiridos mediante digitalización. Finalmente, se realizó la caracterización del lazo de Costas intradino empleando una señal eléctrica post-fotodetección digitalizada obtenida a la salida de nuestro receptor digital coherente. Se observó un desempeño muy cercano al obtenido mediante simulación.

Cluster folding optical potential analysis for 6Li+28Si elastic scattering
Authors: Hamada S. , Ibraheem Awad A.
Published: March 2021

Available experimental angular distribution data for 6Li+28Si elastic scattering in the energy range 16 – 318 MeV are re-analyzed phenomenologically on the basis of optical model using Woods-Saxon (WS) potentials for both real and imaginary parts, while the semi microscopic analysis was performed on the basis of cluster folding potential. Cluster folding potential was generated based on the appreciable cluster structure and breakup of 6Li into a deuteron orbiting a core of α-particle. Although several data sets in a wide range of energies are subjected to investigation, the theoretical calculations using the different concerned potentials are fairly reproduced the experimental data in the whole energy range. The extracted real and imaginary volume integrals and reaction cross sections values are compared to the previously reported ones and they found to be in a good agreement
The temporal fluctuation of the inverse participation ratio for localized field modes in three-dimensional percolation system

Published: March 2021

We investigate the structure of the  optical field radiated by the disordered optical nano-emitters randomly incorporated  in three-dimensional cluster of a percolation material. Our numerical studies shown that the temporal variations of the inverse participation ratio (IPR) allow analyzing the extended and localized field structures over a long time range. The properties of IPR and the dynamics of the lasing emitters allow to find the characteristic time scales when the localization of the field in a general three-dimensional disordered system occurs. The studied effect opens new perspectives to control the optical fields localization in modern optical nano-technologies.
The Journey of Self-Defence through Sound in Claudia Rankine’sCitizen
Authors: Lina Ajlani Lana
Published: March 2021

In Citizen: An American Lyric, Claudia Rankine creates a powerful contemporary embodiment of the evolution of sound in African American vernacular tradition. In this close reading, the poem’s oral expression is explored through a sonic lens and linguistics. From the forced sibilant silence of [s] to the vocalized plosive protest of [b], the poem’s sonic journey calls for louder self-defence in the fight against inequality. Rankine is pushing the public to stop, take in the stories of micro- and macroaggressions, and listen to the magnitude of their impact and interruptions in and of African American lives.
Literal and Symbolic: the Language of Asceticism in Two Lives of St Radegund
Authors: Wehlau Ruth
Published: March 2021

Ascesis as practised within the early church combined a variety of qualities and functions: combat with the devil, suffering and mortification of the flesh, separation from the world, and preparation for death. It was also a means by which those saints who were not martyrs demonstrated heroic action; through asceticism saints created and maintained power. Hagiographers, in turn, described the ascetic actions of saints in order to construct a sense of the saint's body as a holy place, a locus of power. And yet, ascetic behaviour is not transparent of interpretation; hagiographers represented ascetic practices, and thus sainthood itself, differently. These differences are readily apparent in the two major lives of St Radegund.

The tigertooth croaker, Otolithes ruber (Bloch and Schneider 1801), was studied to determine its reproductive biology characteristics for 34 months from March 2015 to November 2017. A total of 7,977 individuals were sampled and the measured total lengths (TL) ranged from 8.1 cm to 32.1 cm (16.70 ± 2.53 cm ) and 10.0 cm to 33.5 cm (17.95 ± 2.95 cm) for male and female, respectively. The length-weight relationship can be summarized as W = 0.00521 L3.18 and W = 0.00837 L3.01 for female and male, respectively. The length at first maturity of this species was determined to be 13.95 cm, which is smaller compared to other studies. The overall sex ratio of this species was 1:0.8, with males dominating the female sex (P < 0.05, X2 = 64.3). In addition, synchronized development of male and female gonads was observed. It was also verified that mature individuals were present all throughout the study period indicating that this species spawn continuously and the presence of juveniles during the sampling period indicated continuous recruitment. Mean monthly GSIs indicate July to November as the main spawning season of this species. The in-site occurrence of mature and juvenile stocks in the bay further implicates that San Miguel Bay is a nursery ground for this species. The fecundity varied between 3,420 to 422,100 with an average fecundity of 86,142 eggs. Lastly, the spawning potential ratio is still above the limit reference point (SPR = 0.36), indicating that the stock can still replenish their biomass.

The development of new information and communication technologies increased the volume of information flows within society. For the security forces, this phenomenon presents new opportunities for collecting, processing and analyzing information linked with the opportunity to collect a vast and diverse amount data, and at the same time it requires new organizational and individual competences to deal with the new forms and huge volumes of information. Our study aimed to outline the research areas funded by the US defense and intelligence agencies with respect to social forecasting. Based on bibliometric techniques, we clustered 2688 articles funded by US defense or intelligence agencies in five research areas: a) Complex networks, b) Social networks, c) Human reasoning, d) Optimization algorithms, and e) Neuroscience. After that, we analyzed qualitatively the most cited papers in each area. Our analysis identified that the research areas are compatible with the US intelligence doctrine. Besides that, we considered that the research areas could be incorporated in the work of security forces provided that basic training be offered. The basic training would not only enhance capabilities of law enforcement agencies but also help safeguard against (unwitting) biases and mistakes in the analysis of data.

Ketegangan dan konflik di Laut China Selatan juga tidak hanya terjadi diantara beberapa negara ASEAN yang batas lautnya saling berhimpitan, tetapi juga terjadi dengan China yang turut mengklaim wilayah Laut China Selatan dan Amerika Serikat yang turut memiliki kepentingan ekonomi dan politik atas wilayah ini. Potensi konflik terbuka telah mendorong negara-negara untuk mengoptimalkan hubungan sipil-militer negaranya dalam menjaga kedaulatan laut. Pengumpulan data dan metode yang digunakan dalam penelitian ini adalah menggunakan metode kualitatif dengan studi literatur dari berbagai sumber yang relevan dan berkaitan serta memiliki jangka waktu yang kontemporer dengan penelitian. Hasil penelitian ini melihat bahwa konflik di Laut China Selatan ini tidak lepas dari peran sipil dan juga militer yang masuk terhadap ranah negara-negara Asia Tenggara yang bersengketa, dimana setiap aspek hubungan antara negara khususnya hubungan sipil dan militer menjadi penentu dimana suatu negara dapat menjadikan suatu kebijakan yang dapat mempengaruhi arah dari konflik yang terjadi di Laut China Selatan ini.Kata Kunci: Laut China Selatan, Konflik, Hubungan Sipil-Militer, Asia Tenggara.
Création d’une « Échelle de comportement alimentaire de l’enfant prématuré vers une alimentation au biberon » (ECEPAB)
Authors: Chopin M. , Téton M. , Chauvel J.
Published: March 2021

L’oralité est un axe essentiel de la prise en soin des enfants grands prématurés. Ainsi, la qualité de la tétée des enfants nourris au biberon est une de nos préoccupations dans le cadre de l’autonomisation alimentaire. L’observation des compétences nécessaires à la coordination succion–déglutition– respiration peut être un appui dans le choix de la stratégie d’alimentation adaptée à lamaturation du nouveau-né prématuré. Nous n’avons pas trouvé d’outil clinique permettant cette évaluation. L’objectif de cette étude a été de créer une échelle d’observation comportementale et de prouver sa reproductibilité dans le temps intra- et interobservateur. Nous avons réalisé une étude prospective monocentrique incluant des enfants nés avant 33 semaines d’aménorrhée strictes (n = 65). Les tests de fiabilité interobservateurs ont abouti à un accord excellent entre professionnels soignants (coefficient de Kappa de 97 %). L’échelle semble très reproductible. Elle peut être une aide pour identifier les compétences des nouveau-nés et permettre l’évaluation de la qualité de l’alimentation au biberon.

Introduction : Le taux de mortalité néonatale précoce constitue un bon indicateur de la qualité des soins et du niveau de développement économique et social d’une population. Le but de notre travail est de déterminer la prévalence, le profil étiologique et les facteurs de risque de la mortalité néonatale précoce.

Méthodes : Il s’agit d’une étude rétrospective descriptive réalisée, au service de médecine et de réanimation néonatale du centre de maternité et de néonatologie de Tunis, sur une période de neuf mois de janvier à septembre 2017. Durant cette période, 3 560 nouveau-nés ont été hospitalisés dans ce service de réanimation néonatale. Au sein de cette cohorte, 150 patients sont décédés en période néonatale précoce.

Résultats : L’incidence de la mortalité néonatale précoce est de 15 pour mille naissances vivantes. Le taux de mortalité néonatale très précoce survenant les 24 premières heures de vie est de 15 % ; 60 % sont décédés au-delà de 48 heures de vie. Le taux de prématurité est de 68 %. Les principales causes de ces décès néonatals précoces sont une cause infectieuse dans 38,6 % des cas, soit une infection néonatale bactérienne précoce dans 25 % des cas, soit une infection nosocomiale secondaire dans 14 % des cas, une malformation congénitale (18,7 %) ou une asphyxie périnatale (APN) [12,7 %]. Les principaux facteurs de risque de mortalité néonatale précoce sont le non-suivi des grossesses, le bas niveau socio-économique, la prématurité, le faible poids de naissance, l’APN, les malformations cardiaques et du système nerveux central.

Conclusion : La mortalité néonatale précoce reste encore élevée. Pour essayer de la réduire, on insiste sur l’amélioration du suivi des grossesses, la prévention de la prématurité et l’amélioration des infrastructures néonatales.
Glossophobic Experience Amongst MPSPC Philippines Pre-service Teachers Through Oral Speech Presentations
Authors: Fagsao Jonnelle , Mi-ing Julie Grace
Published: March 2021

Most individuals are not born to be public speakers; they are educated to be developed as one. When they are in front of an audience being the focus of attention, they experience emotions leading to nausea and excessive sweating because of fear and anxiety. Individuals who have a fear of speaking in public suffer from strong fear in social performance situations and social spheres, which is known as glossophobia. This research aims to discover the different factors that cause speaking anxiety among the pre-service teachers of Mountain Province State Polytechnic College - Teacher Education Department (MPSPC-TED) in Philippines and to suggest strategies that could help prevent them from having glossophobia problem. Samples of interview output, coding, and careful analysis and interpretation of the gathered data from the selected 50 undergraduate students who had research oral presentations, oral lesson demonstrations, and oral speaking presentations have been transcribed and found out major themes that cause glossophobia problems, i.e., linguistic obstacles, audience’s manifestation, mastery of the topic and particular motives. Knowing what causes these problems, this study proposed the DISRUPT strategy to reduce students’ public speaking anxiety effectively.
