How do Partners Benefit from IT Use in Supply-Chain Management: An Empirical Study of Taiwan’s Bicycle Industry
Authors: Li Jing , Chen Chien-Wen , Wu Chi-Hui , Hung Hsing-Chun , Lin Ching-Torng
Published: April 2020

To be sustainable and growing amongst uncertain environments and intensive global competition, supply-chain network leaders have established supply-chain management systems (SCMS) to leverage the resources and knowledge of their partners to achieve greater supply-chain capabilities (SCC) to respond to market changes and complexity. Although several studies have investigated the benefits to network leaders from these systems in various industries, little attention has been paid to the delivery of substantial benefits and advantages to its partners. Based on information technology (IT) applications and SCC literature, this paper proposes a model relating partners use of SCMS to benefits. Data from 168 partners using an SCMS implemented by a leading bicycle supply chain in Taiwan to test the hypotheses that SCC and operational performance has a mediating role linking SCMS use in order to affect a partner’s performance. The results indicate that SCMS implementation has a significant impact on SCC, which in turn create a significant positive effect on operational (sustainable) performance, ultimately leading to improved growth rate and profitability in partners. Another interesting finding of the research is that SCMS cannot directly affect financial performance. In addition, from sustainable performance aspects, it is revealed that IT enables supply chain management (SCM) to achieve environmental value through information sharing (up and down), process integration (vertical and horizontal) and automation (i.e., planning, operation and control). This finding highlights the importance for maximizing benefits and sustainability for the whole supply-chain partners, the IT implementation must be integrated with the sustainable development goals and inserted in the eco-operation supply-chain platform process. The results also contribute to the debate in prior studies by disclosing why so many partners could not find to gain benefit from these IT implementations. Furthermore, this study represents the first attempt to examine how partners benefit from IT use in SCC for traditional industry.

Authors: Porru Mario , Serpi Alessandro , Mureddu Mario , Damiano Alfonso
Published: April 2020

Presented in this paper is a Multistage Design Procedure (MSDP) for planning and implementing Public Charging Infrastructures (PCIs) to satisfy intracity charging demand of Electric Vehicles (EVs). The proposed MSDP splits planning and design processes into multiple stages, from macroscale to fine-scale levels. Consequently, the preliminary results achieved at each stage can be refined at the subsequent stages, leading to determine the accurate number and precise geographical location of each charging point. The main advantage of the proposed approach is that it splits a very complicated procedure into multiple and simpler stages, at each of which appropriate goals, targets and constraints can be included. As a result, the iterative interactions among all the stakeholders involved in the PCI design process are significantly simplified. The proposed MSDP has been employed in the planning and design of the PCI of the Italian island of Sardinia, accordingly to all the public bodies.
The Behavioral Pattern of Chinese Public Cultural Participation in Museums
Authors: Wang Wende , Fu Mozhuang , Hu Qingwu
Published: April 2020

Studying the cultural participation model of the public and its influencing factors is important for the sustainable development of regional culture. Therefore, in this study, we determined which factors influence the cultural participation of the Chinese public. Firstly, we extracted the key features of the motivation and timing for a museum visit with multiple correspondence analysis (MCA), and explored the relationship of the features of different motivations with the frequency and duration of the public’s visits to the museum. Secondly, we determined the monotonicity of the influence of ordinal variables on cultural participation behavior and identified the mechanism through which the independent variable influences public cultural participation with categorical regression (CATREG). Finally, we analyzed the research data from the museum audience survey in the Hubei Provincial Museum and a national public culture participation survey. We found that education, occupation, academic discipline, income, distance, age, and sex affect the public’s museum participation. This indicates that to guarantee the public’s cultural rights and promote sustainable development, education, planning, and other aspects must be coordinated in cultural management to increase public cultural participation, rather than removing the economic threshold for public cultural participation through public finances alone.

Authors: Zhang Hao , He Jie , Shi Xiaomeng , Hong Qiong , Bao Jie , Xue Shuqi
Published: April 2020

Over the past decade, the rapid development of e-commerce and express industries in China has resulted in huge environmental costs. Compared with manufacturing industries, the values of green innovation are less recognized in logistics industries. To promote the green practices in logistic enterprises, it is imperative to have a thorough understanding of the determinants of green innovation adoption. To this end, this paper performs an empirical investigation into the intentions to adopt green innovation from 196 Chinese express companies. The determinant variables were constructed from the perspective of technology characteristics (perceived green usefulness and perceived integration ease of use), stakeholder pressure (government, customer, and platform pressures), and social influence. Then, a 20-item scale was designed based on the literature review and expert opinions. The results revealed the significant positive effects of technology characteristics and social influence on the intentions to adopt green innovation. Meanwhile, only the platform pressure was significant with the adopting intentions among the variables from stakeholder pressure. Moreover, variables from technology characteristics were found to have meditation effects between social influence and adopting intentions. Based on the findings, theoretical and practical implications are proposed to promote the green and sustainable development of express companies in China.

Authors: Huang Ching-Hsu , Liu Shih-Min , Hsu Nai-Yun
Published: April 2020

Although food surplus and food waste issues are extremely important, the amount of literature published on these topics is astonishingly low by our observation. The relationships between food surplus/food waste and economic/environmental sustainability have not yet been holistically assessed and discussed. The main purpose of this study is to understand global food surplus and food waste issues in order to tackle the economic sustainability and environmental sustainability crisis. Content analysis was used to analyze 500 relevant materials and was conducted by NVivo 12 Plus software. The results contain seven countries, six organizations, and six continents, providing a framework to recognize the economic and environmental sustainability crisis. In addition, six major organizations and regions were identified and were found to be relevant to the important issues of food surplus, food waste, the sharing economy, economic sustainability, and environmental sustainability. With the trend of globalization, this study highlights some preliminary evidence for reducing food waste, for conflicts of the sharing economy, and for regulated sustainability. Further research and regulations in terms of economic and environmental sustainability are strongly suggested.
A Conceptual Framework to Understand the Dynamics of Rural–Urban Linkages for Rural Flood Vulnerability
Authors: Jamshed Ali , Birkmann Joern , Feldmeyer Daniel , Rana Irfan Ahmad
Published: April 2020

Rural areas are highly vulnerable to floods due to limited social, economic, and physical resources. Understanding rural vulnerability is vital for developing effective disaster risk reduction strategies. Even though rural areas and cities are intrinsically linked, rural vulnerability was assessed without considering its relation to cities. Numerous theoretical frameworks on systemizing and assessing vulnerability were developed with varying level of scope and depth in terms of scale, dimensions, and components. Nevertheless, these frameworks did not explicitly mention the impact of flood or other hazards on the linkages between spatial units i.e., rural and urban. This study aims to understand and conceptualize the rural vulnerability with respect to the dynamics of rural–urban linkages in the case of flood events. To do so, current literature on rural–urban linkages, vulnerability, as well as factors that influence them were critically reviewed. Taking into account the main elements of rural–urban linkages (flow of people, information, finances, goods and services), components of vulnerability (exposure, susceptibility, and capacity), and factors (social, economic, institutional, infrastructural, spatial, and environmental), a unified framework is proposed. The framework underscores that the role of rural–urban linkages is essential to fully understand rural flood vulnerability. Moreover, the framework highlights the role of spatial factors—city size and proximity to the city—as crucial to comprehend rural vulnerability. This framework can be used as a tool for understanding multifaceted rural vulnerability for climate change adaptation and disaster risk reduction considering spatial development perspective. In this context, empirical investigations can be made to validate the proposed framework and policies can be introduced accordingly. Overall, the proposed framework can help recognize concepts and links of vulnerability, rural–urban dependencies, and rural development dynamics.

Authors: Kang Jun , Lee Hyun Jun , Jeong Seung Hwan , Lee Hee Soo , Oh Kyong Joo
Published: April 2020

The real estate auction market has become increasingly important in the financial, economic and investment fields, but few artificial intelligence-based studies have attempted to forecast the auction prices of real estate. The purpose of this study is to develop forecasting models of real estate auction prices using artificial intelligence and statistical methodologies. The forecasting models are developed through a regression model, an artificial neural network and a genetic algorithm. For empirical analysis, we use Seoul apartment auction data from 2013 to 2017 to predict the auction prices and compare the forecasting accuracy of the models. The genetic algorithm model has the best performance, and effective regional segmentation based on the auction appraisal price improves the predictive accuracy.

Authors: Salizzoni Emma , Pérez-Campaña Rocío , Alcalde-Rodríguez Fernando , Talavera-Garcia Ruben
Published: April 2020

Although widely, as well as recently explored, the concept of urban resilience still poses important issues in terms of its operationalization. For this reason, best practices that show how the resilience concept has been turned into planning practice are much needed. This article presents and discusses the case study of the Charca de Suárez Nature Concerted Reserve, an urban wetland situated along the Andalusian coast (Spain), to contribute to filling the gap on the operationalization of urban resilience at the local planning level. In the Charca, an adaptive co-management and design approach has been successfully put into practice to foster local urban resilience. Starting from some recent key studies on planning and management policies for urban resilience, we propose a framework to read, understand and evaluate the Charca experience, and more generally, resilience-based projects. The analysis highlighted the following crucial key aspects for urban resilience in the Charca case study: A collaborative governance model; and the building of community-capitals. The Charca de Suárez Nature Concerted Reserve can actually be acknowledged as an innovative planning practice, a source of inspiration for visions and experiments oriented to urban resilience.
Modeling the Adoption and Diffusion of Mobile Telecommunications Technologies in Iran: A Computational Approach Based on Agent-Based Modeling and Social Network Theory
Authors: Sabzian Hossein , Shafia Mohammad Ali , Ghazanfari Mehdi , Bonyadi Naeini Ali
Published: April 2020

Understanding the mechanism underlying the mobile telecommunications technologies (MTTs) diffusion in a country is crucial for telecom planners to know how to accelerate their diffusion by designing appropriate scenarios. Considering the technology diffusion as a bottom-up process, this study is aimed at exploring this mechanism, drawing on insights from diffusion of innovation theory and social network theory. Accordingly, an agent-based model is proposed to investigate how MTTs are diffused in Iran over time. The results of this study show, (1) social network of Iranian society seems more similar to a Watts–Strogatz small-world network than a Barabási–Albert preferential attachment network, where the clustering coefficient is high and average path length is low, (2) compared to the compatibility parameter, the advertisement parameter not only is less influential on diffusion of a targeted MTT (i.e., 4G) but also is not necessary for it, and (3) scenarios having the least number of steps and turning points are more appropriate for continuous diffusion of 4G. The proposed study is empirically validated against real-world data ranging from 7/1/2017 to 12/31/2017. We believe it provides telecom planners insights regarding MTTs diffusion mechanism in a social complex structure and the how of scenario designing for increasing their diffusion.
Utilizing Bivariate Climate Forecasts to Update the Probabilities of Ensemble Streamflow Prediction
Authors: Sung Jang Hyun , Ryu Young , Seo Seung Beom
Published: April 2020

In order to enhance the streamflow forecast skill, seasonal/sub-seasonal streamflow forecasts can be post-processed by incorporating new information, such as climate signals. This study proposed a simple yet efficient approach, the “Bivar_update” model that utilizes bivariate climate forecast to update individual probabilities of the ensemble streamflow prediction. The Bayesian updating scheme is used to update the joint probability mass function derived from historic precipitation and temperature data sets. Thirty-five dam basins were used for the case study, and the modified Tank model was embedded into the ensemble streamflow prediction framework. The performance of the proposed approach was evaluated through a comparison with a reference streamflow forecast model, the “Univar_update” model, that reflects only precipitation forecast, in terms of deterministic and categorical streamflow forecast accuracy. For this purpose, multiple cases of probabilistic precipitation and temperature forecasts were synthetically generated. As a result, the Bivar_update model was able to decrease the errors in forecast under below-normal conditions. The improvements in forecasting skills were found for both measures; deterministic and categorical streamflow forecasts. Since the proposed Bivar_update model reflects both precipitation and temperature information, it can compensate low predictability especially under dry conditions in which the streamflow’s dependency on temperature increases.

Published: April 2020

This study analyzes the relationship between agricultural foreign direct investment (FDI) and food security on Belt and Road Initiative (BRI) countries in a panel framework over the period 2006–2015 using correlation analysis, the specific-effect model, and the 2SLS technique. The study aims to: first, analyze the correlation between agricultural FDI and food security for each country, individually; then, investigate whether there is a direct relationship, using the specific-effect model. Finally, by taking one step further, this study uses the 2SLS method to determine whether there is an indirect relationship through agricultural productivity. Our results show that the sampled countries have clear differences in the direction of the relationship between food security and agricultural FDI. But, in general, the agricultural FDI has a positive direct and indirect effect on food security; this effect is seen clearly when the country attracts agricultural FDIs steadily.
Does Institutional Embeddedness Promote Regional Enterprises’ Migration? An Empirical Analysis Based on the “Double Transfer” Strategy in Guangdong, China
Authors: Long Rongjun , Lang Wei , Li Xun
Published: April 2020

Against the background of globalization, institutional embeddedness has become an important theoretical tool to understand the changes in regional economic patterns. This paper starts by discussing the theory of location choice of enterprises and then uses the statistical method of negative binomial regression to analyze the impact factors of enterprises’ transfer from the perspective of institutional embeddedness by taking Guangdong Province, China, as a case study area. It was found that informal institutional factors such as the same language, the same industry, and geographical proximity have significant positive effects on the transfer of regional enterprises. Formal institutions such as counterpart assistance are the core driving force of enterprise transfer, while traditional economic factors such as cost comparative advantage have no significant impact on the transfer of regional enterprises. This research shows that the transfer of regional enterprises is greatly influenced by the current regional institutional environment. Therefore, it is important for future policy makers to consider the regional institutional environment and to deepen regional institutional embeddedness to advance urban and regional development.
Relationships between Renewable Energy Consumption, Social Factors, and Health: A Panel Vector Auto Regression Analysis of a Cluster of 12 EU Countries
Authors: Caruso Giulia , Colantonio Emiliano , Gattone Stefano Antonio
Published: April 2020

One of the key indicators of a population’s well-being and the economic development of a country is represented by health, the main proxy for which is life expectancy at birth. Some factors, such as industrialization and modernization, have allowed this to improve considerably. On the other hand, along with high global population growth, the factor which may jeopardize human health the most is environmental degradation, which can be tackled through the transition to renewable energy. The main purpose of our study is to investigate the relationship between renewable energy consumption, social factors, and health, using a Panel Vector Auto Regression (PVAR) technique. We explore the link between some proxy variables for renewable energy consumption, government policy, general public awareness, the market, lobbying activity, the energy dependence on third countries, and health, spanning the period from 1990 to 2015, for a cluster of 12 European countries characterized by common features. Specifically, our analysis shows the importance of having a stringent policy for the development of renewable energy consumption and its influence over other social factors, rather than the existence of causal relationships between health and renewable energy consumption for the analyzed countries. This kind of analysis has a great potential for policy-makers. Further, a deeper understanding of these relationships can create a more effective decision-making process.

Published: April 2020

Rabies, caused by rabies virus (RABV), is a fatal neurological disease that still causes more than 59,000 human deaths each year. Type III interferon IFN-λs are cytokines with type I IFN-like antiviral activities. Although IFN-λ can restrict the infection for some viruses, especially intestinal viruses, the inhibitory effect against RABV infection remains undefined. In this study, the function of type III IFN against RABV infection was investigated. Initially, we found that IFN-λ2 and IFN-λ3 could inhibit RABV replication in cells. To characterize the role of IFN-λ in RABV infection in a mouse model, recombinant RABVs expressing murine IFN-λ2 or IFN-λ3, termed as rB2c-IFNλ2 or rB2c-IFNλ3, respectively, were constructed and rescued. It was found that expression of IFN-λ could reduce the pathogenicity of RABV and limit viral spread in the brains by different infection routes. Furthermore, expression of IFN-λ could induce the activation of the JAK-STAT pathway, resulting in the production of interferon-stimulated genes (ISGs). It was also found that rRABVs expressing IFN-λ could reduce the production of inflammatory cytokines in primary astrocytes and microgila cells, restrict the opening of the blood-brain barrier (BBB), and prevent excessive infiltration of inflammatory cells into the brain, which could be responsible for the neuronal damage caused by RABV. Consistently, IFN-λ was found to maintain the integrity of tight junction (TJ) protein ZO-1 of BBB to alleviate neuroinflammation in a transwell model. Our study underscores the role of IFN-λ in inhibiting RABV infection, which potentiates IFN-λ as a possible therapeutic agent for the treatment of RABV infection.

Assessment of Intra- and Inter-observer Measurement Variability in a Radiographic Metacarpophalangeal Joint Osteophytosis Scoring System for the Horse
Authors: Lacitignola Luca , Imperante Annarita , Staffieri Francesco , De Siena Rocco , De Luca Pasquale , Muci Arianna , Crovace Antonio
Published: April 2020

The study evaluated the intra- and inter-observer measurement variability of an osteophytosis metacarpophalangeal joint scoring system. Ten (n = 10) dorso/palmar, latero/medial, and oblique views of equine metacarpophalangeal joints affected by osteoarthritis were examined. Nine assessment points were graded (scale: 0–3) twice by five veterinary students (inexperienced group, I) and four equine veterinary surgeons (expert group, E). The grades for each of the nine factors were summed to obtain the osteophytosis score. The variability between the two measurements was −2.04 ± 3.5, 95% CI −3.04 to −1.03 for the I group. For the E group, they were 0 ± 1.43, 95% CI −0.45 to 0.45. In the evaluation of the same radiographs, the I group had a coefficient of variability (CV) of 37.29%. The correlation was r = 0.90%. The CV between groups was 28.85%. The mean difference between the two observations was -0.03 ± 0.29 in the E group and 0.22 ± 0.77 in the I group. The I group showed a greater CV when the score was low (r = −0.78) compared to the E group, where the CV was independent of severity of osteophytosis (r = −0.47). The osteophytosis scoring system is an easily applicable and feasible system to be used by observers with different levels of experience, but inexpert observers may need additional training or may need to be helped by reference images. These data are validated by the low inter- and intra-observer measurement variability results in the E group. Therefore, the scoring system proposed seems to be a repeatable instrument applicable to the radiographic score of the severity of metacarpophalangeal joint osteoarthritis.

Highly conductive topological semimetals with exotic electronic structures offer fertile ground for the investigation of the electrical and thermal transport behavior of quasiparticles. Here, we find that the layer-structured Dirac semimetal PtSn

This work provides a paradigm for the decoupling of the electron and hole transport behavior of highly conductive topological semimetals and is helpful for developing topological semimetals for thermoelectric energy conversion.
Codifying Game‑Based Learning: Development and Application of
LEAGUÊ Framework for Learning Games
Authors: Tahir Rabail , Wang Alf Inge
Published: April 2020

Educational games are now seen as effective learning tools.
However, there is a gap in the literature regarding the core
dimensions of Game‑based learning (GBL) for comprehensive design,
analysis, and evaluation due to inconsistent use of elements. The
literature on GBL reports an extensive diversity of elements used
for the design and evaluation of GBL without any categorization of
micro and macro‑level elements. Hardly any studies systematically
decompose these aspects to derivate factors/sub‑factors, obstructing
identification of any clear pattern. The problem is not the scarcity
of GBL research but inconsistency in terminology, scope, definition,
and usage of elements leading to the absence of a holistic view of
GBL for effective design and evaluation. This study bridges the gap
by outlining terminology and scope with four conceptual levels and
then systematically categorizing GBL elements by scope, definition,
and usage. The methodology used is directed content analysis of GBL
literature collected through a previous systematic literature
review. Dimensionalization of GBL and further decomposition into
factor/sub‑factors based on theoretical constructs, has resulted in
a consistent and clear pattern delineating the structure of the
educational game design, analysis, and evaluation. Further codifying
metrics and mapping the relationship among GBL dimensions deduce
into a conceptual framework (called LEAGUÊ) that facilitates greater
insight into the process of learning with educational games, where
to focus and what to evaluate. The LEAGUÊ framework can be applied
for the analysis, design and evaluation of learning games. The
framework is put in practice by utilizing the framework components
(dimensions, factors/sub‑factors and relations) to develop three
items: 1) an analysis instrument, 2)a card‑based ideation and design
toolkit, and 3) an evaluation guide that can assist educational game
designers, researchers, educators and evaluators for the analysis,
design and evaluation of learning games respectively. This paper
exemplifies the application of framework for the analysis of
learning games using the analysis instrument (developed using LEAGUÊ
framework) with one case study as an example.
‘Sasanian’ silver plate from al-Ṣabāḥ Collection in light of aesthetic features of Sasanian toreutics
Authors: Skupniewicz Patryk
Published: April 2020

Recently published silver plate from al-Sabah Collection, of unknown provenance, has been firmly attributed as Sasanian. In fact, technically, it is related to the Sasanian silverwork however aesthetic examination allows to raise the doubts whether it is genuine. The plate must be compared not only with central-Sasanian artworks but all ancient ‘Oriental silver’, including pieces attributed as Hephtalite or Sogdian. The design of the plate does not have any relation with any of the known examples of late antique oriental toreutics. Central scene of heroic combat with powerful beast or beasts has never been surrounded with the ring containing other hunting scenes is unknown as well. The disbalanced decorum is even more clear when we remind that the central scene shows hunting on foot and the marginal ones – mounted. The details of fixed aesthetic elements – position of personages, beasts, weapons do not belong to Sasanian canon. The unique nature of the plate might result from many factors but the combination of unknown provenance and lack of relation to legitimate Sasanian canon require utmost cautiousness towards the object.

Authors: Wang Hao , Chen Jingjun , Do James , Rashtian Hooman , Liu Xiaoguang
Published: April 2020

This paper reports an approach to designing compact high efficiency millimeter-wave fundamental oscillators operating above the fmax=2 of the active device. The approach takes full consideration of the nonlinearity of the active device and the finite quality factor of the passive devices to provide an accurate and optimal oscillator design in terms of the output power and efficiency. The 213-GHz single-ended and differential fundamental oscillators in 65-nm CMOS technology are presented to demonstrate the effectiveness of the proposed method. Using a compact capacitive transformer design, the single-ended oscillator achieves 0.79-mW output power per transistor (16 μm) at 1.0-V supply and a peak dc-to-RF efficiency of 8.02% (VDD=0.80 V) within a core area of 0.0101mm2, and the measured phase noise is -93:4 dBc/Hz at 1-MHz offset. The differential oscillator exhibits approximately the same performance. A 213-GHz fundamental voltage-controlled oscillator (VCO) with bulk tuning method is also developed in this work. The measured peak efficiency of the VCO is 6.02% with a tuning rang of 2.3% at 0.6-V supply.

Published: April 2020

Permintaan bahan bakar fosil semakin meningkat sementara pasokannya kian berkurang dari waktu ke waktu. Hal ini mendorong untuk mengembangkan sumber energy alternative seperti biomassa sebagai energy baru terbarukan. Biomassa dapat dikonversi menjadi energy alternative dalam bentuk bio-oil melalui proses pirolisis. Komposisi biomassa seperti lignoselulosa (lignin, selulosa dan hemiselulosa) didekomposisi dengan proses pirolisis menjadi komponen organic seperti fenol, alkohol, keton, aldehid dan ester. Bio-oil merupakan bahan bakar terbarukan dan lebih ramah lingkungan dari pada bahan bakar fosil (minyak bumi). Bio-oil dapat disebut sebagai "green energy" dalam banyak aplikasi untuk menggantikan minyak bumi dan juga dapat digunakan sebagai "green chemical". Dalam aplikasinya, bio-oil dapat digunakan sebagai energy ramah lingkungan karena memiliki emisi lebih rendah dari pada bahan bakar fosil. Senyawa fenolik memiliki komposisi paling dominan dalam bio-oil di mana fenol memiliki banyak kegunaan untuk resin, antiseptik, pengawet dan desinfektan. Produksi bio-oil dalam penelitian ini dilakukan dengan proses pirolisis lambat pada reactor dengan kisaran suhu 250-400oC selama 30 menit. Eksperimen ini dilakukan denganbahan baku kulit durian pada ukuran10 mesh dan 20 mesh. Analisia GC-MS digunakan untuk mengetahui komponen bio-oil. Produk bio-oil memiliki viskositas 1,189 cP, dan densitas 1,031 g/cm3 dan pH 6. Bio-oil mengandung beberapak omponen seperti senyawa fenolik (66,37%), metil ester (2,71%), siklridridana (3,66%), benzocycloheptariene (3,39), indole (5,19%), glisin (3,01%), pentadekana (4,07%), 5-tert-butylpyrogallol (3,07%), asam bromoacetic (3,40%) dan asamtetradecanoic (5,16%).
EXPERIMENTAL RESEARCH OF DUST POWER OF FILTERING MATERIALS FOR ANTI-DUST RESPIRATORS
Authors: Cheberiachko S. , Cheberiachko Y. , Radchuk D. , Pustovoi D.
Published: April 2020

The purpose is to carry out experimental investigations of the physicochemical properties of filtering materials for the manufacture of two-layer filters of high dust capacity of dust respirators for operating conditions of coal mines. The dust capacity of filter materials for the manufacture of two-layer filters was determined at a dust concentration of about 400 mg/m3, with a final pressure drop of 500 Pa (according to the requirements of DSTU EN 143 for filters of the 2nd class of protection). "AFA VP-10" filters with a diameter of 36 mm were used; "VLO 200" laboratory scales; "HS43" electronic stopwatch; the pressure drop on the filter boxes was monitored using an "MKV 250" compensation micro manometer. It is established that in order to increase the dust capacity of dust filter respirators, their filter should be combined with filter materials with different physicochemical properties to ensure a uniform distribution of dust sediment over the thickness of the filter layer. It is proved that the increase in the duration of the protective action of dust suppressors is possible due to the effect of aftofiltration, when the settled dust layer on the filter surface independently delays aerosol particles. The dependence of the differential pressure on the filter of the dust respirator on the change in the density of packing of fibres with dust is obtained, which allows determining the rational physicochemical properties of the materials of the filter layers of the filter for maximum dust intensity. It was found that the smallest increase in the air flow resistance of the multilayer filter was recorded by combining the filter layers with the fibre packing density of 30 and 60 g/cm3, respectively. The experimental dependences are established that will allow finding a rational combination of filter layers to ensure maximum dust capacity of the filter.

Validating RDF data becomes necessary in order to ensure data compliance against the conceptualization model it follows, e.g., schema or ontology behind the data, and improve data consistency and completeness. There are different approaches to validate RDF data, for instance, JSON schema, particularly for data in JSONLD format, as well as Shape Expression and Shapes Constraint Language, which can be used with other serialization as well, e.g., RDF/XML or Turtle. Currently, no validation approach is prevalent regarding others, selection commonly depends on data characteristics, background knowledge and personal preferences . In some cases, the approaches are interchangeable; however, that is not always the case, making it necessary to identify a subset among them that can be seamlessly translated from one to another. During the NBDC/DBCLS 2019 BioHackathon, we worked on a variety of topics related to RDF data validation, including (i) development of ShEx shapes for a number of datasets, (ii) development of a tool to semi-automatically create ShEx shapes, (iii) improvements to the RDFShape tool, and (iv) enabling validation schema conversion from one format to the other. Here we report on our BioHackathon achievements.

The functional optimization of the composition of radiopharmaceutical pairs based on the prostatespecific membrane antigen (PSMA) for the radionuclide theranostics of castration-resistant prostate cancer was carried out. The analysis of radiation-physical and dosimetric characteristics of 9 radionuclides for diagnostic components of theranostic pairs and 6 radionuclides for therapeutic components is carried out. It was shown that positron-emitting radionuclides 18F and 68Ga should be considered optimal for the diagnosis and monitoring of the effectiveness of theranostics, and 177Lu beta-emitting radionuclide and 225Ac alphabeta-emitting radionuclide should be considered as the radionuclide therapy. The values of the total and organ radiation risks of secondary radiation-induced cancers in patients who have completed several courses of theranostics are calculated. It is shown that for 2 teranostic pairs based on 177Lu‑PSMA the radiation risk is higher than significant, while for 2 teranostic pairs based on 225Ac the risk falls within the range of a significant level. The calculated radiological criteria for discharge of patients after a course of theranostics from nuclear medicine departments show the fundamental possibility of performing an outpatient treatment regimen using any of the 4 considered theranostic pairs.

A survey was conducted to assess the flora affected by mistletoe species and the identification of chlorophyll pigments in Sokoto State University. The study was aimed at surveying the flora affected by mistletoe species and identifies their chlorophyll pigments within the Sokoto State University campus. The study site was divided into three sampling areas, based on the studied species and infestation of trees by mistletoes. The species of mistletoe, Tapinanthus globiferus, was common to all the three types of trees (Azadirachta indica, Psidium guajava, and Acacia nilotica). A. nilotica had the highest rate of infestation by mistletoe (T. globiferus) with the percentage of 85.7% in area A, 91.7% in area B, and 82.3% in area C. The estimation of pigment content of chlorophyll in mistletoe leaves showed that all the mistletoe found on the three different types of trees had the same pigment content of chlorophyll-a, chlorophyll-b, and carotene.
Ozone Gas: Scientific Justification and Practical Guidelines for Improvised Disinfection using Consumer-Grade Ozone Generators and Plastic Storage Boxes.

Published: April 2020

We describe direct measurements of ozone concentration achievable in small enclosed containers (plastic storage boxes) for use as improvised decontamination systems for small articles such as disposable PPE (N95 masks, nitrile gloves, etc.), clothing, mail and small packages, food, and other miscellaneous articles. The emphasis is on the reliable and sustained generation of ozone gas concentrations of sufficient concentration and duration to create an effective virucidal environment to achieve more than 95% to 99% viral inactivation, based upon the data already published in the peer-review literature on this topic.

The suggestion that ozone be used to inactivate virus is certainly not a new idea. Our objective in this report is to make clear that the necessary levels of ozone can be improvised using simple, easy-to-use, inexpensive, and widely available supplies, and that there is every theoretical and experimental reason to believe that this approach is as highly effective in viral inactivation by ozone as are the far more expensive, complex, cumbersome, and less available equivalent ozone (and other) disinfectant systems that have themselves become unavailable during times of pandemic crisis.

Using multiple types of readily available commercial ozone generators, concentration in the tested improvised enclosure is tracked over time to assess ozone charging and decay rates, and the ozone quenching effects of items placed in the box. Generator performance is compared against published ozone dosage values for virucidal and antimicrobial activity. Bubbler and box-fan-type ozone generators were found to be effective at achieving and maintaining target concentrations of 10ppm ozone or higher, whereas automotive cigarette lighter and universal serial bus type plug in “air freshener” ozone generators could not achieve the target concentrations in these experiments. Calculations and practical guidelines for assembly and effective use of an ozone box for improvised decontamination are offered.

The majority of this report is directed toward the scientific justification and rationale for this approach. The end of the document summarizes the findings and offers simplified designs for the construction and use of ozone boxes as an improvised method of disinfection.

Published: April 2020

A Teoria de van Hiele para o Desenvolvimento do Pensamento Geométrico tem sido considerada como guia ao ensino e à aprendizagem de Geometria. Este modelo consiste em dois grandes princípios: descrição da estrutura cognitiva, caracterizada por níveis mentais hierárquicos a serem atingidos pelos alunos e pela metodologia de ensino para que estes níveis sejam alcançados, orientando professores quanto à tomada de decisão relacionada ao ensino. A partir de um estudo sobre os modelos de desenvolvimento do pensamento sobre a linguagem de funções, este trabalho tem o objetivo de relatar o processo de testagem e validação de um modelo de níveis de desenvolvimento para a aquisição do conceito de função, baseado no modelo de Van Hiele.  Para isso, foram aplicadas atividades variadas a alunos do Ensino Médio. Os resultados comprovam a validade da escala proposta, já que a classificação dos alunos da amostra se distribuiu por todos os níveis, obedecendo a hierarquia.

DID TECHNOLOGY IMPROVE SAFETY? AN EMPIRICAL STUDY OF CONTROLLED FLIGHT INTO TERRAIN ACCIDENTS
Authors: Yang Cheng-Hua , Alex
Published: April 2020

Aviation safety has been affected greatly by technological improvements. A series of Ground Proximity Warning Systems (GPWSs) were developed to prevent accidents during Controlled Flight into Terrain (CFIT). This study analyzed the role of GPWS (or Enhanced GPWS, EGPWS) in flight safety history to determine how effective GPWS/EGPWS was in terms of preventing CFIT. The result showed a substantial increase in CFIT accidents due to the rapid growth of aviation development. This situation improved after the mandatory installation of GPWSs in commercial aircraft. However, the legal requirement did not apply to all general aviation. Most CFIT accidents have involved general aviation aircraft that do not have GPWS/EGPWS installed on board. Thus, the mandatory requirement should apply to all civil aircraft. CFIT accidents have also been reduced considerably in developed countries whereas they remain a major issue in developing countries.
TRENDS IN AIRPORT SURFACE ACCESS IN THE LONDON MULTI-AIRPORT SYSTEM
Authors: Moxon Richard
Published: April 2020

The London multi-airport system is described and changes in ownership from state organisations to competing private enterprises are assessed. A taxonomy of United Kingdom government action related to airport planning policy is presented with critical analysis in relation to airport surface access strategy. Changes in public transport use by passengers and employees at London airports are quantified to illustrate the success or otherwise of government policy. Passenger groups (defined by nationality and trip purpose) driving the increase in public transport are identified. Current London airport surface access strategic targets for passengers and employees are compared with the early versions suggested by the government to highlight the changed airport approach. Emerging surface airport access issues at London’s airports are discussed.
