Authors: Burkhart Sarah , Verdonck Michele , Ashford Theresa , Maher Judith
Published: February 2020

Opportunities exist for nutrition and dietetic (N&D) professionals to contribute to sustainable development and support actions towards the attainment of the UN’s Sustainable Development Goals (SGD’s). Students undertaking higher education are well-placed to develop skills and capabilities in creative and critical problem solving for sustainability. However, there is limited literature exploring nutrition and dietetic students’ perceptions of sustainability that would help to inform an effective and constructively aligned embedding of sustainability content and active learning opportunities into curriculum. This descriptive cohort study design utilised a 17-question online survey to explore 95 Australian N&D undergraduate students’ self-reported familiarity with and perceived importance of sustainability and related concepts, and view of sustainability for future practice. Participants reported being more familiar with the term environmental sustainability and related concepts than economic or social sustainability. Varying levels of familiarity of 42 sustainability related concepts within economic resilience, environmental integrity, social development and cross-cutting issues were reported. Most participants (82%, n = 78) reported sustainability was very important in general (82%, n = 78), and for professional practice (63%, n = 60). Over half of the participants identified government led initiatives to address the future of society (65%, n = 71). Our study highlights the complexity of sustainability in a discipline specific context and the need for understanding students’ perceptions of sustainability to inform N&D curriculum design.
Historical School Buildings. A Multi-Criteria Approach for Urban Sustainable Projects
Authors: Guarini Maria Rosaria , Morano Pierluigi , Sica Francesco
Published: February 2020

It is recognized, in Europe and elsewhere, that there is a need to implement sustainable urban intervention policies based also on the recovery of existing public real estate assets. In Italy, the schools are a significant part of public property. At this time (2019), many buildings destined for teaching need to be redeveloped, both from a structural and plant engineering point of view, and with regard to the management of the spaces available for teaching and social activities. Although, there have been many attempts by the legislator to regulate the modus operandi in the school construction field, it is clear that there is a lack of a unique regulatory system in which the technical and functional-managerial aspects relating to the same school are considered together. On this basis, with this study a multi-criteria evaluation protocol to support intervention planning for the redevelopment of existing school buildings is proposed. The study defines an evaluation framework with which we can establish the design priorities to be carried out in accordance with the building features and community needs. The evaluation framework is tested on a renewal project regarding a school building located in the historic center of Rome (Italy).

Published: February 2020

Analyzing the driving factors of regional carbon emissions is important for achieving emissions reduction. Based on the Kaya identity and Logarithmic Mean Divisia Index method, we analyzed the effect of population, economic development, energy intensity, renewable energy penetration, and coefficient on carbon emissions during 1990–2016. Afterwards, we analyzed the contribution rate of sectors’ energy intensity effect and sectors’ economic structure effect to the entire energy intensity. The results showed that the influencing factors have different effects on carbon emissions under different stages. During 1990–2000, economic development and population were the main factors contributing to the increase in carbon emissions, and energy intensity was an important factor to curb the carbon emissions increase. The energy intensity of industry and the economic structure of agriculture were the main factors to promote the decline of entire energy intensity. During 2001–2010, economic growth and emission coefficient were the main drivers to escalate the carbon emissions, and energy intensity was the key factor to offset the carbon emissions growth. The economic structure of transportation, and the energy intensity of industry and service were the main factors contributing to the decline of the entire energy intensity. During 2011–2016, economic growth and energy intensity were the main drivers of enhancing carbon emissions, while the coefficient was the key factor in curbing the growth of carbon emissions. The industry’s economic structure and transportation’s energy intensity were the main factors to promote the decline of the entire energy intensity. Finally, the suggestions of emissions reductions are put forward from the aspects of improving energy efficiency, optimizing energy structure and adjusting industrial structure etc.

Published: February 2020

Walking is an important transport mode for sustainable cities, but the usability of pedestrian environments for people with impaired vision is very limited after dark. This study compares the usability of a walkway, operationalized in terms of (i) the pedestrian’s ability to orient themselves and detect infrastructure elements, and (ii) the perceived quality of lighting in the environment (evaluated in terms of the perceived strength quality and perceived comfort quality). The study was performed in a city in southern Sweden, along a pedestrian route where observations and structured interviews had previously been conducted and after an intervention involving installing new lighting systems with LED lights. A mixed method analysis involving participants with impaired vision (N=14) showed that the intervention generally improved the walkway’s usability: observations indicated that the participants’ ability to orientate themselves and detect infrastructure elements increased, and the interviews showed that the intervention increased the perceived strength quality of the lighting along the walkway. However, the effects on the perceived comfort quality were unclear. It is therefore important to carefully evaluate new lighting systems to reduce the risk of creating an inappropriate lighting design that will limit walking after dark by people with impaired vision.
The Economic Effects of Climate Change Adaptation Measures: Evidence from Miami-Dade County and New York City
Authors: Kim Seung Kyum
Published: February 2020

This research examines the economic impact of climate change adaptation measures on the housing markets of two representative coastal cities in the United States located along the Atlantic Ocean. The results shed light on how adaptation measures and investments influence housing values and local real estate markets with respect to their place-based and local forms of implementation. Numerous quantitative approaches, with the use of geospatial data, panel-data hedonic regressions, and difference-in-differences analyses, are used to examine changes in property values associated with climate adaptation measures and the dynamics of risk perception. The results also signal how risk perception and hurricane characteristics are reflected in housing markets, thereby shedding light on the effects of anticipatory and reactive adaptation strategies on property values in these coastal communities. Collectively, the study suggests which adaptation strategies and characteristics can contribute to maximizing both community resilience and economic benefits against the weather extremes caused by climate change.
Analysis of the Indoor Thermal Environment and Passive Energy-Saving Optimization Design of Rural Dwellings in Zhalantun, Inner Mongolia, China
Authors: Shao Teng , Zheng Wuxing , Jin Hong
Published: February 2020

Zhalantun city is located in a severely cold region of China. The cold climate and long winter bring challenges to the energy-saving design of rural dwellings in this area, while the poor economic conditions restrict the application of energy-saving technology. This paper aims to propose an optimal combination of passive design parameters by investigating, testing, and analyzing simulations of Zhalantun rural dwellings, which have a particular architectural pattern. Field measurements during winter show that the indoor temperature of a traditional house is low and fluctuates greatly, and the inner surface is prone to easy condensation. Through thermal comfort surveys, neutral and acceptable temperature ranges were obtained to provide indoor calculation parameters for an energy-saving design. Numerical simulations of heating energy consumption were conducted on the typical building models using DesignBuilder. The influence of different design factors on energy consumption was evaluated. Orthogonal experiments were designed to optimize a series of design parameter combinations to reduce the energy consumption of Zhalantun rural houses and to determine the sequence and significance of the effect of these design factors on energy consumption. Results show that the optimal parameter combination based on orthogonal experiments can obviously reduce energy consumption and have better economic benefits without considering mechanical methods. This can provide a basis for improved energy-saving designs and indoor thermal environments in such rural dwellings.

Published: February 2020

Rapid growth in the food-energy-water (FEW) nexus literature calls for an assessment of the trajectory and impacts of this scholarship to identify key themes and future research directions. In this paper, we report on a bibliometric analysis of this literature that focuses on (1) examining publication trends and geographic focus of research, (2) identifying research hotspots and emerging themes, (3) assessing the integrated nature of research, and (4) reflecting on major developments and ways forward. We used Elsevier’s SCOPUS database to search for publications from January 2011 to May 2018 on the FEW nexus, and analyzed the final sample of 257 publications using BibExcel and Vosviewer software tools. The analysis showed steady growth in publications since 2011 with a sharp upturn in 2015 and 2016, coinciding with major funding calls. Thematic analysis of abstracts revealed a strong focus on quantitative resource interlinkages with limited attention to qualitative institutional capacities and intersectoral governance challenges. Term co-occurrence network map showed the term “investment” connected with a large number of frequently cited terms, while the term “governance” demonstrated much weaker links. We reflect on how these findings may help us better understand and address the enduring challenge of transitioning from nexus thinking to action.

Published: February 2020

The energy sector is undergoing radical changes, and this transition is expected to accelerate all over the world over the coming years. In our recent research, we conducted a questionnaire survey at different levels and asked the experts in the area, the businesses involved in the issue, the operators and maintainers of existing systems, as well as the potential consumers and end users, about their knowledge and intentions related to renewable energy sources. Our empirical research can be divided into three parts. Our exploratory research was based on expert interviews, which show that the growing importance of localization is unquestionable, but the economic, social, and existing infrastructures impose significant barriers to the widespread adoption of certain technologies. Regarding the population survey, we see that the skepticism experienced in previous years has been replaced by a kind of expectation reflecting openness. In addition, it can be stated that in many cases technological development is faster than the possibility of its adaptation. Our gender tests significantly support men’s better knowledge of the subject and the fact that biomass (despite its major importance) is not one of the most known renewable energy sources.

Published: February 2020

The ever-changing external environment and the challenges and signals transmitted by the European Single Market have greatly contributed to the dynamism of SMEs in Europe. From the privileged place held by the entrepreneur in SMEs, the present study aims to investigate the role of managerial skills in the sustainable development of small and medium enterprises, focused on self-awareness, emotional intelligence, and interpersonal skills of entrepreneurs. The investigation method consisted of the distribution of anonymous questionnaires to a representative sample of entrepreneurs, in the Mehedinți County, Romania. The collected data were centralized, processed, and assessed. The results of this analysis revealed, besides the emotional intelligence and interpersonal skills which have reached a suitable level, a low level of self-awareness. Therefore, this has been considered as a potential barrier towards sustainable development of SMEs in the analyzed region. However, the high level of emotional intelligence, accompanied by an increasing trend of interpersonal skills as the manager’s experience in working with people increases, is a strong argument for the sustainable development of SMEs. The study comes to support the public policies concerning small and medium-sized entities by using a model of managerial skills testing for applicants. In this way, an increase of the transparency of financing decision and the effectiveness of financial support are ensured.
RNA Sensing of Mycobacterium tuberculosis and Its Impact on TB Vaccination Strategies
Authors: Burkert Sanne , Schumann Ralf R.
Published: February 2020

Tuberculosis (TB) is still an important global threat and although the causing organism has been discovered long ago, effective prevention strategies are lacking. Mycobacterium tuberculosis (MTB) is a unique pathogen with a complex host interaction. Understanding the immune responses upon infection with MTB is crucial for the development of new vaccination strategies and therapeutic targets for TB. Recently, it has been proposed that sensing bacterial nucleic acid in antigen-presenting cells via intracellular pattern recognition receptors (PRRs) is a central mechanism for initiating an effective host immune response. Here, we summarize key findings of the impact of mycobacterial RNA sensing for innate and adaptive host immunity after MTB infection, with emphasis on endosomal toll-like receptors (TLRs) and cytosolic sensors such as NLRP3 and RLRs, modulating T-cell differentiation through IL-12, IL-21, and type I interferons. Ultimately, these immunological pathways may impact immune memory and TB vaccine efficacy. The novel findings described here may change our current understanding of the host response to MTB and potentially impact clinical research, as well as future vaccination design. In this review, the current state of the art is summarized, and an outlook is given on how progress can be made.

Exploration and optimization on the usage of micro-perforated panels as trim panels in commercial aircrafts
Authors: Chenxi L.I. , Ying H.U. , Liyan H.E.
Published: February 2020

Micro-perforated panels (MPPs), as an alternative to porous materials for sound absorption, have been commonly used in electronic industries and aircraft engines but are barely used in aircraft cabins. The effect of MPPs on the sound insulation and absorption properties of aircraft
cabin panels has been investigated in this article. Theoretical modeling has been conducted on an aircraft cabin panel structure with a trim panel replaced by an MPP trim panel, using the transfer matrix method and the classic MPP theory. It is indicated by the theoretical results that, although
the sound transmission loss (STL) of the cabin panel with an MPP trim panel is lower than that with an un-perforated panel, the MPP trim panel can significantly enhance the sound absorption coefficient of the entire cabin panel structure. Based on the well-developed MPP theory, the sound absorption
coefficient of an aircraft cabin panel with an MPP trim panel can be improved by optimizing the MPP's parameters at a specific frequency. Taking an engine frequency 273 Hz as an example, the optimization can increase the sound absorption coefficient to 1 by using the doublelayered MPPs. When
the thermal acoustic insulation blanket is considered, although the STL of the proposed structure with double-layered MPP trim panels in a diffuse field is lower than those without MPP trim panels, the sound absorption in the cabin is significantly enhanced due to the double-layer MPP trim
panel at the specific engine frequency and across all frequencies. The STL of the structure with double-layered MPP trim panels and TAIB can be higher than 40 dB from 880 Hz in a diffuse field, which implies its effectiveness as sound insulation structure in aviation industry. MPP trim panels
provide a new idea for the design of aircraft cabin panels and areworthy of further research

PRAGMATIC MARKERS “WELL” AND “SO” IN FINDING NEMO AND THEIR VIETNAMESE TRANSLATION EQUIVALENTS IN "ĐI TÌM NEMO"
Authors: Nguyen Nhung Ngoc Thao
Published: February 2020

Pragmatic markers, considered as one of the best-known sources of troubles in translation, have received considerable attention from researchers. This study therefore, offers a contrastive analysis of “well” and “so” occurring in an extract of the film Finding Nemo and their translation in the Vietnamese dubbed and subtitled versions. The occurrences of "well and "so" in the data were analyzed according to a functional classification framework and compared with their translation equivalents by contrastive analysis (CA) to find out the translation strategies applied and to evaluate translation effectiveness. The findings reveal that "well" tendsto be omitted more often than "so" in the Vietnamese translations while "so" appears to be the easier item whose functions are usually well captured by single-word equivalents. The study also shows how carefulanalysis may help the translators achieve effective and natural translation. Implications for EFL teaching and translating tasks as well as suggestions for further research are also discussed.

Authors: Borisov Aleksey , Korabelnikov Daniil , Romanov Vadim
Published: February 2020

Introduction. Hypoparathyroidism after hyroidectomy is treated with oral calcium and vitamin-D supplements. Everyday prolonged use of calcium and vitamin D medications can lead sometimes to hypercalcemia that can cause Akute Kidney Injury (AKI) and Arterial Hypertension. We report on a clinical case of a man patient with postoperative hypoparathyroidism who presented with hypercalcemia, AKI and Chronic Kidney Disease (CKD) as a result of prolonged treatment with Dihydrotachysterol and calcium medications.

Сlinical case. A male patient, 59 y.o., 11 years ago underwent total thyroidectomy, since that time was daily medicated with l-thyroxine 125-150 mcg, dihydrotachysterol 15 drops (approx. 0,62 mg), calcium in different forms without monitoring the blood and urine levels. He had high arterial pressure up to 200/120 mm Hg, treated with amlodipine 10 mg daily. After 5 years he took onemonth treatment with non-steroidal antiinflammatory drugs for pain relief because of a rib fracture. That time he underwent first AKI with full recovery. After 5 years a few AKI recurred with hypercalcemia. Dihydrotachysterol and calcium were cancelled, but since that time patient kept on getting non-prescribed Dihydrotachysterol and calcium in the same doses. After 1 year more in relapse series a puncture biopsy of the kidney showed nephrocalcinosis, chronic interstitial nephritis and CKD (С4А3) was diagnosed. The patient was treated successfully by dis-continuation of the above drugs, intravenous fluid administration and enhancement of calcium renal excretion. The patient is currently free of complaints for about 3 months.

Сonclusion. It is important for clinicians to monitor calcium and 25-OH-D levels in blood serum during the prolonged treatment with calcium and vitamin D medications to prevent a hypercalcemia that can lead to AKI, CKD and other sever complications.

Published: February 2020

This research will focus on the Tourist Destination Areas (DTW) of the museum considering the motives and tourist destinations are more unique, besides recreational motives there is an element of learning. The pattern of tourism in museum objects shows the fact that the number of tourist visits is relatively fixed from year to year. Investment in tourist destinations is very large, especially in artificial destinations. Visitors to tourist destinations, although satisfied, are less likely to visit again. So to foster loyalty it needs to be redefined. So this study aims to prove that high decisions do not necessarily form high loyalty. Therefore loyal tourists are not only willing to come back but are willing to promote the destinations visited either by word of mouth or recommend to others. This research uses a quantitative analysis method with an inferential approach. Theoretically, quantitative analysis in a study can be approached from two approaches, the first using descriptive statistics and the second using inferential statistics. Both types of statistics have different characteristics, both in terms of analytical techniques and the objectives that will result from the analysis. The output of this research is to develop the concept of strategy formulation for the marketing of tourist attraction objects especially museum destinations, and to develop the concept of marketing strategies in increasing tourist visits.

Published: February 2020

We have been employing novel printing technologies in three-dimensional printed electronics applications, to form electronic devices on curved or three-dimensional object surfaces. In this paper, we report on a newly developed printing technology named ‘soft blanket reverse-offset’ (SBR) printing, which was developed to create wide and flat patterned layers with uniform thicknesses on curved surfaces. SBR printing is an extension of conventional reverse-offset printing and uses an extremely thick and soft blanket (referred to as a “soft blanket”) as an offset roller. We also created a new thick stencil printing plate and a two-layered soft blanket construction that avoids the formation of contact-defects. In addition, we have also succeeded in printing wide and flat patterned layers onto curved surfaces using commercially available silver nanoparticle inks. The printed layers are also characterized by uniform thicknesses and low resistivities, equivalent to those of layers printed on planar substrates.

A tanulmány a generátor állórészek belső alakhibájának vizsgálatával foglalkozik, melyet magas és alacsony hőmérsékleten való tesztelési eljárás idéz elő. Ez a fajta meghibásodás befolyásolhatja a generátorok megfelelő működését, mivel a generátor egy másik alkatrészének, a rotornak a forgása során rezgések léphetnek fel. Kijelenthető, hogy ennek a hibának a hatása csökkenti a generátor teljesítményét. A publikáció célja annak vizsgálata, hogy a különböző tesztelési paraméterek úgy, mint hőmérséklet, tesztelési idő, az állórész el van-e látva rezgéscsillapító gyűrűvel vagy sem, milyen hatással bírnak. A kísérlet megtervezéséhez és végrehajtásához a teljes faktoriális kísérlettervezés módszerét alkalmaztuk. Az egyes elemek hengerességének mérése Taylor Hobson Talyrond 365 gyártmányú köralak- és helyzethiba-mérőberendezésen valósult meg. A mért adatokból speciális viszonyszámokat alkottam, annak érdekében, hogy meghatározzam azt a paramétertartományt, mely a legnagyobb mértékű deformációt okozza.

Power ow is basically the ow of active and reactive power. Power ow analysis is used to determine the
steady state operating condition of a power system. In short it is to nd the approximate values of various
bus voltages, their phase angle, active and reactive power ows through different branches, generators and loads under steady
state condition .Heuristic methods are generally referred as experience based techniques for solving problem, learning and
discovery. Heuristics are simple and efcient rules coded by evolutionary processes. In this paper, GA, genetic algorithm, one of
such heuristic algorithms have been used to do the power ow analysis in a simple six, nine, fourteen, twenty six and thirty bus
system.
