A COMPUTATIONALLY EFFICIENT ENERGY MANAGEMENT STRATEGY FOR A PLUG-IN FUEL-CELL HYBRID ELECTRIC VEHICLE COMPOSED OF A MULTI-INPUT CONVERTER
Authors: Akar Furkan
Published: April 2019

Fuel cell vehicle technology has drawn wide attention because of the environmental and economic issues related to excessive usage of fossil fuels. Fuel cells are known for their unidirectional environmental friendly operation; however, they have low power density and suffer from slow dynamics. Therefore, a sole fuel cell system cannot meet the requirements of an electric vehicle whose power demand is quite dynamic. In a way of hybridizing a fuel cell with energy storage devices, it can be possible to overcome aforementioned problems. A plug-in fuel cell hybrid electric vehicle system, equipped with a battery and an ultra-capacitor, is proposed in this work. In this system, a single multi-input converter is utilized to control source energies. Moreover, this work develops a computationally efficient energy management strategy which is essentially a frequency decoupling method basically taking the advantage of easily applicable low pass filters. In this strategy, a polynomial scales the fuel cell and battery power levels to regulate ultra-capacitor voltage. The whole system is tested via a simulation model after the detailed analysis of the multi-input converter.
Investigation of the interactions between titanium and calcium zirconium oxide (CaZrO3) ceramics modified with alumina
Authors: Lu Ming-Wei , Lin Kun-Lin , Lin Chien-Cheng
Published: April 2019

Powdered mixtures of CaO, ZrO2 and Al2O3 in various ratios were hot pressed.
The mixtures reacted with titanium at 1600?C for 30min in argon to evaluate
the suitable ceramic crucibles for casting of titanium. The interfacial
microstructures between titanium and ceramic composites were characterized
using X-ray diffractometer, scanning and transmission electron microscope.
The produced hot pressed mixtures that were chemically bonded together,
contained calcium aluminate (CaAl2O4), calcium dialuminate (CaAl4O7), cubic
zirconia (c-ZrO2), and calcium zirconium oxide (CaZrO3). The increase in
Al2O3 amount led to the decrease in CaZrO3 amount and an increase in the
amount of CaAl2O4, CaAl4O7 and c-ZrO2 due to the reaction of CaO and Al2O3.
At the end of the reaction of the ceramic mixtures with Ti at 1600?C for
30min, the acicular ?-Ti and ??-Ti were formed at the interface of Ti and
the composites containing up to 10 vol.% Al2O3. In composites containing
more than 20 vol.% Al2O3, Ti3Al5 was found at the interface instead of ?-Ti
and ??-Ti. Furthermore, CaZrO3, ZrO2 and Ca3Al2O6 existed on the sides of
the ceramic far away from the interface. CaZrO3/Al2O3 composites with less
than 20 vol.% Al2O3 could be a potential crucible or mould material for
productive applications in titanium casting.
Femtosecond laser pulse inducing hydrophilicty and hydrophobicity on polycarbonate surfaces
Authors: Wang Z. K. , Zheng H. Y. , Thwe A. M. , Chen Guojie , Lam Y. C.
Published: April 2019

This study investigated the use of ultrashort femtosecond laser pulses to induce either hydrophilic or hydrophobic surfaces on polycarbonate (PC). It has been observed that controlled modification of wettability could be achieved over a wide range of the water contact angle from below 5° to above 150°. It has been shown that the pulse energy fluence and total energy deposition onto PC are the important factors in determining the laser–PC interaction and therefore the different level of wettability on PC surface. X-ray photoelectron spectroscopy-spectra measurement indicates that the modification was caused dominantly by laser induced chemical bond changes. The changes in surface morphology may not noticeably contribute to the surface wettability. The results would be useful in microfluidics chip design and fabrication with controlled surface wetting properties.

Authors: He Zhijian , Xie Xiaozhu , Long Jiangyou
Published: April 2019

Surfaces with efficient photothermal conversion have great value in both science and industry. In this study, large-area hierarchical microstructures and nanostructures with high light absorptance over a wide spectrum range from ultraviolet to the near-infrared region were fabricated on copper surfaces by a low-cost green nanosecond laser system. By optimizing the morphology of laser-induced surface structures, the average light absorptance in the wavelength range of 220–800 nm and 220–2500 nm can be as high as 98.9% and 91.9%, respectively. Moreover, the laser-processed surfaces demonstrated a photothermal conversion efficiency of more than 52% under 15 sun illuminations. The authors also showed that the desalination efficiency was greatly improved when the prepared surfaces were used as the solar energy harvesting surfaces in the solar energy driven desalination system.

Authors: Adedayo Adelowokan Oluwaseyi , Olusegun Оkutimiren Adeteji
Published: April 2019

The situation in Nigeria is rapid population growth with high level of unemployment rate. The theoretical proposition of the Okun’s law suggests an indirect relationship existing between unemployment and output growth. This study tests the validity of Okun’s law by examining the impact of youth employment generation on sustainable growth in the Nigerian economy. We modeled real gross domestic product against unemployment rate, population growth, labour and government expenditure between 1986 and 2017. The empirical findings show that there is short- and long- run relationship existing between unemployment rate, population growth and output growth in Nigeria. Hence, study recommends that the activities by the government in promoting economic growth in the country should be geared towards promoting employment for the people in other sector.
REALIZATION OF EVALUATIVE UTTERANCE IN DIFFERENT TYPES OF CONTEXT
Authors: Prihodko Ganna , Prykhodchenko Oleksandra , Galaidin Andrii
Published: April 2019

The article is focused on the problem of the interconnection of the context and the evaluative utterance. Evaluation of different world’s fragments is, of course, a considerable part of human cognitive activity. Special attention is paid to signals-indicators, which can be linguistic and extralinguistic in nature. The present paper highlights the actualization of evaluative utterance in micrcontext, and macrocontexts of the minimum, average and maximum size. In the process of realization of the evaluative utterance within the frame of micrcontext, the linguistic context is based on signals-indicators, while the structure of the stylistic context consists of various semasiological and syntactic expressive means and stylistic devices. While updating the evaluation in macrocontexts of the minimum and average size, the linguistic context is frequently mixed, and the configuration of the stylistic context in most cases includes different semasiological and syntactic expressive means and stylistic devices; but the macrocontext of the maximum size is linguistic, and the stylistic context is only its background part. The results obtained confirm the idea that the correlation between the evaluative utterance and context helps to understand encoded in the evaluative utterances presuppositions of the communication that is the speaker's communicative intentions associated with his epistemic state.

Published: April 2019

The key symptom of depression is lowering the mood, but this is not the only sign of depression. Depression is a disease in which the symptoms reach various intensities and occur in many configurations. We distinguish the following types of depression: reactive, endogenous, neurotic, anankastic, agitated, large and small, morning (subclinical and subliminal), seasonal, masked, psychotic, postpartum, drug resistant, in children and adolescents, in the elderly, involutional, organic , in bipolar disorder, dysthymia, depression and anxiety, and in somatic diseases. Psychotherapy is now a popular and effective method of treating depression. The effects of treatment after the use of antidepressants appear only after a few weeks from the beginning of therapy. Old-generation medicines: these are tricyclic antidepressants (TLPDs), inhibitors of neuromediator reuptake and monoamine oxidase enzyme (IMAO) inhibitors. The new generation of drugs is distinguished by selective serotonin reuptake inhibitors (SSRIs), selective serotonin and noradrenaline reuptake inhibitors (SNRIs), four-ring drugs, noradrenaline reuptake inhibitors, selective reversible MAO inhibitors, and drugs with other mechanisms of action. Phototherapy (treatment of light) is currently a widely accepted method of winter depression therapy. Other treatments for depression include electroconvulsive therapy and transcranial magnetic stimulation.

Published: April 2019

The transition to alternative energy sources requires a long period, attracting significant investments in the process of creating and developing environmentally friendly fuels. Creating an environmentally safe, energy-efficient economy is a prerequisite for sustainable development of each country. The above-mentioned factors determine the relevance of the study of the problems of the functioning and development of energy, which is mainly due to the economic expediency of renewable energy and the requirements of the country's energy independence. The objective of the article is to determine the features of ensuring the energy efficiency of the Ukrainian economy using alternative energy sources. Research shows that the development of alternative energy will allow us to move away from the use of traditional fuels and create the prerequisites for the energy independence of countries. Taking into account the natural factors and the significant dependence of Ukraine on imported primary energy sources, it is determined that solving the problem of increasing energy efficiency of the economy is possible only with the stimulation of the use of alternative energy sources. The most promising sources of energy are identified, namely: biofuels, wind energy, geothermal energy, solar energy, solar thermal, controlled thermonuclear fusion, energy of tides and effluents. The recommendations for realization of such directions of the policy of the state regulation in the energy sphere as energy security, energy efficiency, energy saving are given.

THE TEXT – THE READER – THE LITERARY WRITING: A COGNITIVE AND NARRATOLOGICAL PARADIGM
Authors: Matsevko-Bekerska Lidiia
Published: April 2019

The article presents the study of some aspects in the specificity of the dialogue between the artistic text and the consciousness of the addressee. This issue is quite actively discussed in the modern literary criticism – both in theoretical approaches to analysis and in applied poetics studies. To a large extent, the methodological and terminological apparatus for examining the cognitive specificity of literature has been formed in classical narratological studies and refined in the latest developments. The article focuses on clarifying the essence of the reader as an important element of representing the consciousness, present in the artistic narrative. The specificity of the reader's presence is determined not only by its mediation status, but also by active participation in the creation and coexistence of several worlds: the intentional modus, its fiction embodiment, as well as the individual personal experience of their synthesis. Possible forms of the addressee’s presence in the space of the literary world are modelled in accordance with narrative coordinates. The specificity of each form of reader’s presence is determined by the conventional status, the narrative contour of the text, the objective intentional premises, as well as the ways of permeating into the artistic world, the ways of discovering the meaning, due to which the reading takes place as a holistic phenomenon. From the standpoint of cognitive narratology, every reader's projection has its own peculiarities that influence its place in the process of literary communication. It has been shown that the receptive significance of the literary work consists in the possibility of multiplying the meanings, implementation of the harmonious reader's understanding, corresponding to the original sense. With the increase of interval between the author and the reader, the content of the work is proportionally schematized, and with refinement of the scheme, every single interpretation acquires reliability.

SOCIAL AND POLITICAL ETHICS ACCORDING TO THE POLISH PRIEST JÓZEF MAJKA
Authors: Mazur Jan , Majkowski Władysław , Blaise Hameni
Published: April 2019

The presented text is an attempt to answer the question: how was understood the social and political ethics by the Priest Professor Józef Majka (1918-1993) - one of the leading minds of Catholic social teaching in Poland? It is, of course, about capturing the specificity of this understanding, comparing it with the perspectives of other outstanding authors.
Views of Priest Majka on this subject were included mainly in His book: Social and Political Ethics (1993). In His opinion, this kind of ethics is not only a group of philosophical considerations, but a real attempt to show Catholic social and political ethics. He wrote: "We do not think that it would be possible at all to develop a sensible system of social ethics, especially political, without referring to Christian principles and focusing on the message of the ultimate goal of a man in the Gospel message" (Majka, 1993:12).
It seems that this unambiguous reference to the values and principles of the Gospel, recognizing them as necessary in the construction of a sensible system of social and political ethics allows us to consider His concept as original, thoroughly Christian, marked by a testimony of faith and penetrated by intellectual depth.
It can be stated  that the social ethics in the sense of Father Majka is not an ideology, but an integral part of Catholic social science, situating above all in the area of  philosophy and theology, where it finds the necessary premises for moral principles and norms.
Mutual Education. Towards a model of educational co-creation around the archaeological heritage of Mexico
Authors: Delgado Rubio Jaime
Published: April 2019

Today, the area surrounding the archaeological city of Teotihuacan is suffering a gradual process of destruction due to factors such as: the uncontrolled urban sprawl of neighbouring communities, the conurbation of Mexico City, and the conflictive relationship between the State Institution which is legally responsible for preserving these remains and these centres of population. This represents a multifactorial and convergent problem requiring coordinated action and participation on the part of the Mexican state, the local authorities, and the local population.This article deals with these problems from a generational perspective, based on the fact that, at the present time, thousands of school children and young people from these urban areas are forming criteria or opinions about the problem and learning from the positions taken by different players in the conflict. It is in this context, and via a post-doctoral study period supported by the Mexican National Council of Science and Technology (Consejo Nacional de Ciencia y Tecnología) (CONACYT) and the Institute of Heritage Sciences (INCIPIT-CSIC) in Spain, that we have built a strategy for scientific dissemination, named ‘Arqueólogos en Apuros’ (Archaeologists in Trouble), which consists of a multimedia children’s news bulletin presented by puppet reporters, with the aim of promoting processes of reflection among school children regarding the destruction of the pre-Columbian city and the problems implied by this fact. However, we wish to go beyond the act of simply providing information and hope to generate co-creation processes, in which these children can make decisions regarding the topics, formats, and representation of the news bulletin and can become capable of researching the news for themselves. In this paper, the theoretical and methodological evolution of this project is analysed, along with its successes, failures, and future challenges, which may enable us to establish the ways in which these young people relate to their heritage, reaching beyond the authorized discourse, and to help them to demand their right to preserve, defend, and enjoy this heritage within the framework of the expression of their creativity and spontaneity.
A Missed Partnership: Russia and the US at the Pacific
Authors: Suslov D. V.
Published: April 2019

Both Russia and the United States consider the Asia-Pacific as the center of the world economy and politics and assume the active presence in the region crucial for their security and economic development. They did not have such sharp contradictions there as in Europe or in the post-Soviet space. Moreover, some of their interests in the Asia-Pacific Region coincide – such as preventing Chinese hegemony. In this regard, the Russian-American dialogue and cooperation in the Asia-Pacific could be an important pillar of the positive agenda of their relations and a factor in their sustainability. Due to foreign policy inertia, the inflexibility of the agenda of Russian-American relations and the inability of the parties to go beyond the usual pattern, such a dialogue has not even begun. Both sides demonstrated strategic myopia. This weakened the resilience of US-Russian relations in the face of new challenges and accelerated their deterioration and disruption to a new confrontation. The Asia-Pacific has become another theater of the US-Russian systemic confrontation. However, it is in the interest of bothRussia and the United States to separate relations in this region from their general confrontation. This will create favorable conditions for Russia to build a balanced partnership system in the Asia-Pacific, which is necessary to consolidate its role as an independent global great power. In addition, the Russian-American dialogue on the Asia-Pacific, or at least the weakening of their confrontation in this region, will reduce its polarization and prevent tensions between the US and its Asian allies and partners.
South East Asia – In the Priorities of Russian Policy “Pivot to Asia”
Authors: Rogozhin A. A. , Rogozhina N. G.
Published: April 2019

The foreign policy course “Turn to Asia”, taken by Russia in the early 2000s, was not accompanied, however, by the expansion of interaction with the countries of South East Asia. Despite creating a certain foundation for the development of bilateral and multilateral cooperation, its potential is far from being fully explored. The presence of objective factors hampered its expansion and limited the active involvement of Russia in regional integration processes. The article assesses the prospects for the development of relations with Southeast Asian countries in the context of Russia’s strategic and economic interests in the region and the emerging conditions for their implementation. The authors note that the region has begun to acquire strategic importance for Russia, firstly, for economic reasons, given the dynamics of its growth and the possibility of its involvement in Russian integration projects,secondly, for geopolitical reasons, based on an assessment of its contribution to the formation of a security architecture in the Asia-Pacific region, the principles of which are generally consistent with Russia’s strategic interests, which are realized within the framework of diplomatic and militarypoliticalrapprochement with the countries of South East Asia. The article notes that in building their relations with them, Russia proceeds from the fact that its more active participation in regional affairs may become a factor hindering the establishment of hegemony by one of the great powers in the region, which generally meets the interests of the Southeast Asian countries themselves. At the same time, the authors come to the conclusion that in search of a force  capable of ensuring stability in the region, the choice of Southeast Asian countries is unlikely to stop only on Russia, whose real level of political influence in the region is still low. As for economic cooperation Russia with the countries of South East Asia, in recent years, the interaction between them in the framework of bilateral relations has strengthened, primarily in trade. Russia has a positive balance in trade with the countries of the region. However, investment cooperation between them is small in scope and does not play a significant role in the economies of the counterparty countries. The article provides a detailed analysis of the problems that complicate Russia’s economic cooperation with the countries of South East Asia and offers recommendations for solving them, taking into account the specifics of Russian business and the particularities of the local market development. The authors come to the conclusion that the success of Russia’s economic relations with the countries of South East Asia will largely depend on whether we recognize them as equally important partners as China or India. No political steps taken by Russia in South East Asia will lead to a strengthening of its position in the region, if they are not accompanied by its economic expansion.

Studi kinerja pengendalian gulma lahan kering (herbiciding) pada berbagai metode pengabutan perlu dilakukan untuk membantu petani dalam menentukan pengabutan herbisida optimum.  Tujuan studi ini adalah menentukan efektivitas pengabutan untuk herbiciding pada berbagai metode pengabutan berdasarkan tekanan cairan dan tekanan udara.  Pengabut, atau sprayer, yang digunakan dalam penelitian ini terdiri atas mist blower TASCO MD-150, electric / battery sprayer JITU HX-D18F, dan air blower BOOSTER, sehingga dapat dilakukan penelitian pengabutan dengan 3 perlakuan, yaitu: (1) pengabutan oleh tekanan udara (mist blower), (2) pengabutan oleh tekanan cairan (electric sprayer), dan (3) pengabutan oleh tekanan cairan dan udara (electric sprayer + air blower).  Pengujian ketiga metode pengabutan dilakukan di dalam Laboratorium Alat dan Mesin Proteksi untuk menentukan debit pengabutan efektif, lebar pengabutan efektif, diameter droplet, dan kerapatan droplet.  Pengujian juga dilakukan di areal lahan kering untuk menentukan kapasitas keluaran dan persentase gulma mati.  Analisis dilakukan guna menentukan efektivitas pengabutan pada berbagai metode pengabutan berdasarkan tekanan udara, tekanan cairan, serta gabungan tekanan udara dan cairan.  Hasil penelitian menunjukkan bahwa besar debit pengabutan efektif, lebar pengabutan efektif, diameter droplet, dan kerapatan droplet pada perlakuan pengabutan oleh tekanan udara, pengabutan oleh tekanan cairan, dan pengabutan oleh tekanan cairan dan udara berturut-turut sebesar [0.679 liter/menit, 64 cm, 357.95 µm, 294.99 droplet/cm2], [1.039 liter/menit, 80 cm, 430.12 µm, 89.42 droplet/cm2], dan [1.616 liter/menit, 56 cm, 292.83 µm, 55.48 droplet/cm2].  Besar kapasitas keluaran dan efektivitas pengabutan pada perlakuan pengabutan oleh tekanan udara, pengabutan oleh tekanan cairan, dan pengabutan oleh tekanan cairan dan udara berturut-turut sebesar [6.40 liter/ha, 90.44%], [4.02 liter/ha, 74.99%], dan [3.84 liter/ha, 91.81%].  Semakin kecil ukuran (diameter) dropletnya, maka akan semakin mudah droplet masuk ke stomata gulma sehingga menghasilkan efektivitas pengabutan yang semakin besar dan pemberian aplikasi larutan herbisidanya paling hemat.
Maximum Oxygen Uptake of Male Soccer Players According to their Competitive Level, Playing Position and Age Group: Implication from a Network Meta-Analysis
Authors: Slimani Maamer , Znazen Hela , Miarka Bianca , Bragazzi Nicola Luigi
Published: April 2019

The aim of the present meta-analysis was to compare the maximum oxygen uptake (VO2max) characteristics of male soccer players relative to their competitive level, playing position and age group and the interaction between them. The meta-analysis was based on 16 studies, employing 2385 soccer players aged 10–39 years. Higher-level soccer players showed greater (ES = 0.58 [95% CI 0.08-1.08], SE = 0.25, var = 0.06, z = 2.29, p = 0.022) VO2max performance with respect to their lower level counterparts. Furthermore, lower VO2max values in goalkeepers than defenders (ES = 1.31 (SE 0.46) [95% CI 0.41-2.21], var = 0.21, z = 2.84, p = 0.004) and midfielders (ES = 1.37 (SE 0.41) [95% CI 0.58 to 2.17], var = 0.16, z = 3.40, p = 0.001) were found. Thus, VO2max increased significantly with age (all, p < 0.01): Under 10 versus Under 11 years, Under 11 versus Under 12 years, Under 12 versus Under 13 years, Under 13 versus Under 14 years, Under 14 versus Under 15 years and Under 16-18 versus Under 20-23 years. VO2max performance is the most powerful discriminator between higher and lower-level soccer players. These findings indicate also the need for sports scientists and conditioning professionals to take the VO2max performance of soccer players into account when designing individualized position specific training programs.
Unilateral Knee and Ankle Joint Fatigue Induce Similar Impairment to Bipedal Balance in Judo Athletes
Authors: Ghram Amine , Young James D , Soori Rahman , Behm David G
Published: April 2019

The purpose of this study was to compare the effects of unilateral ankle fatigue versus the knee muscles with and without vision on bipedal postural control. Elite judo athletes who competed at the national level with at least 10 years of training experience, were randomised into KNEE (n = 10; 20 ± 2 years) and ANKLE (n = 9; 20 ± 3 years) groups, who performed dynamic isokinetic fatiguing contractions (force decreased to 50% of initial peak torque for three consecutive movements) of the knee flexors and extensors or ankle dorsiflexors and plantar flexors, respectively. Static bipedal postural control (French Posturology Association normative standards) with eyes open and eyes closed was examined before and immediately after the fatiguing task. Postural variables examined were the centre of pressure (CoP) sway in the medio-lateral and antero-posterior directions, total CoP area sway and CoP sway velocity. Although unilateral ankle and knee fatigue adversely affected all bipedal postural measures, with greater disturbances with eyes closed, there were no significant main group or interaction effects between KNEE and ANKLE groups. Unilateral lower limb fatigue adversely affected bipedal balance, with knee extension/flexion fatigue affecting bipedal postural control to a similar extent as unilateral ankle dorsiflexion/plantar flexion fatigue. Hence unilateral fatigue can affect subsequent bilateral performance or also have implications for rehabilitation exercise techniques. Our findings may be limited to judo athletes as other populations were not tested.
Integration as a task of municipal policy. The exploration of an emerging field of local politics
Authors: Nuissl Henning , Domann Valentin , Engel Susen
Published: April 2019

Based on three empirical case studies, this paper discusses options of addressing social integration as a task of local authorities. It furthermore aims to provide a conceptual scheme for a systematic exploration of this field of local politics. The argumentation starts from the observation that many communities in Germany have taken promising attempts to establish a genuine integration policy at the local level in the wake of recent refugee immigration. Thereby, they bolster the often-heard catchword of 'social integration occurs at particular places' and, at the same time, support both local civil society and local economy in developing their integrative potential. However, the case studies have also shown that an 'integrative urban development' (policy) must not refrain its efforts to the very field of integration policy but should link this policy to further cross-cutting paradigms – i.e., the principles of recognition, backstopping, and social cohesion. Examples from the case studies illustrate how to pursue local integration policies that allow for these principles. Yet, it will always be a matter of framework conditions, experiences and distinct local discourses, which of the proposed strategies, instruments or measures apply.
Coreference Resolution in Vietnamese Electronic Medical Records
Authors: Nguyen Hung D. , Cao Tru H.
Published: April 2019

Electronic medical records (EMR) have emerged as an important source of data for research in medicine andinformation technology, as they contain much of valuable human medical knowledge in healthcare and patienttreatment. This paper tackles the problem of coreference resolution in Vietnamese EMRs. Unlike in English ones,in Vietnamese clinical texts, verbs are often used to describe disease symptoms. So we first define rules to annotateverbs as mentions and consider coreference between verbs and other noun or adjective mentions possible. Thenwe propose a support vector machine classifier on bag-of-words vector representation of mentions that takes intoaccount the special characteristics of Vietnamese language to resolve their coreference. The achieved F1 scoreon our dataset of real Vietnamese EMRs provided by a hospital in Ho Chi Minh city is 91.4%. To the best of ourknowledge, this is the first research work in coreference resolution on Vietnamese clinical texts.Keywords: Clinical text, support vector machine, bag-of-words vector, lexical similarity, unrestricted coreference
Patient-, Caregiver-, and Eye Care Professional-reported Burden of Geographic Atrophy Secondary to Age-related Macular Degeneration
Authors: Singh Rishi P. , Patel Sunil S. , Nielsen Jared S. , Schmier Jordana K. , Rajput Yamina
Published: April 2019

Objective

Geographic atrophy (GA) is a progressive, irreversible advanced form of age-related macular degeneration. There is limited information on the burden of illness of GA from patient, caregiver, and eye care professional perspectives. This study identifies key factors that should be included for assessment in future studies of patients with GA.

Methods

In this cross-sectional qualitative study, patients with symptomatic GA (n = 8), their caregivers (n = 6), and eye care professionals who treat patients with GA (n = 5) were interviewed at US sites. Interview guides were designed to evaluate the understanding of the disease, costs and burden of illness, use of vision aids or services, and impact on emotional or psychological well-being and on daily activities.

Results

Half of the patients mentioned social, psychological, or helplessness issues. Patients reported the impact of GA on sports and outdoor hobbies, meals or food preparation, religious activities, and long-distance travel. Patients reported having stopped driving or changing driving patterns as a major concern. 38% of all patients reported previously modifying their work schedules due to vision impairment. All patients reported the use of at least one vision aid, with 88% of patients purchasing the aids out of pocket. Caregivers reported modifying their schedules to provide assistance as needed and expressed frustration over their inability to improve patients’ health. Eye care professionals noted the emotional impact of vision loss, accidents, and injuries, and identified mental health as a key topic for patients with GA.

Conclusions

Although limited by size, this study indicates that GA has a major negative impact on patients’ and caregivers’ social functioning and health-related quality of life. This study has identified indirect resource use, including caregiving needs, and direct patient out-of-pocket costs as factors relevant to patients with GA. Future larger studies are needed to further characterize the burden of illness of GA for patients and caregivers.

Published: April 2019

n-Type transparent conductors (TCs) are key materials in the modern optoelectronics industry. Despite years of research, the development of a high performance p-type TC has lagged far behind that of its n-type counterparts delaying the advent of “transparent electronics” based on fully transparent p-n junctions. Here, we propose the layered oxysulfide [Cu2S2][Sr3Sc2O5] as a structural motif for discovering novel p-type TCs. We have used density functional theory to screen the thermodynamic and dynamical stability and electronic structure of 24 compositions based on this motif, predicting 2 new p-type TCs and 8 other stable systems with semiconductor properties. Following our predictions, we have successfully synthesized our best candidate p-type TC, [Cu2S2][Ba3Sc2O5], which displays structural and optical properties that validate our computational models. It is expected that the design principles emanating from this analysis will move the field closer to the realization of a high figure-of-merit p-type TC.
A Triple Layer Model to Manage Romania's Health Risks and Educational Consequences

Published: April 2019

This article explores the relationship between education and health from the perspective of revised literature and suggests an exercise combining the scientific theory with applied knowledge to achieve health progress reflected in health indices improvement for individuals and community. The relation between aggregate health condition, food and nutrition receives, through education, a new shape implying a three-way causality analysis to highlight the role of each entity exerting significant influences in the others’ good functioning.Three important issues are considered for the new and comprehensive definition: a) high level of education implies specific health benefits; b) health affects the level of education of the population; and c) living conditions, especially the childhood, affect both the population’s education and the aggregate health of the whole nation.This paper develops the new model to easier identify health risks, from the individuals’ attitude and their behavior in society, throughout life, within the institutional contexts.The conclusion shows that individuals and their personal traits are built, shaped and solidified within the first social frame (family), being permanently affected by surroundings. Subsequently, the influence of the community - through consolidation or disruptive factors - emphasized by political decisions, public establishments and their policies or other institutions – generates different social and cultural contexts whose aggregate consequences will be lasting and influence the national future.

Published: April 2019

Learning can not only be done in the classroom with direct face-to-face activities but can now be done with the help of IT, for example with learned learning. Although learning with vi-learn or e-learn cannot indeed replace overall face-to-face learning in the classroom. The world of education cannot be separated from technological advances such as this study because sometimes in carrying out classroom learning there are obstacles that cannot be avoided. These obstacles can be administrative in nature such as national holidays which coincide with the schedule of courses and cannot be replaced on another day due to limited space and insufficient time. In this study, learning tools for the English for TEP-based learning program have been developed to learn the verbal communication skills of students majoring in chemistry. From the data from the validation results, it can be concluded that learning devices consisting of enrichment modules and worksheets are feasible to be used in learning lessons. Likewise, from the response data, students showed a positive response from students in using enrichment modules and worksheets.
