Historiography of industrial technology transfer in the first third of the XX century.
Authors: Ganin Maksim Alekseevich
Published: August 2022

The article examines the historiography of the transfer of industrial technologies in the first third of the XX century. This historical period is of particular interest to researchers. It was at this time that the Soviet model of forced industrial modernization was taking shape. In order to achieve the set goals in the shortest possible time, the Soviet state most actively used the mechanisms of scientific and technical cooperation with foreign countries. Thanks to the scientific and technical policy pursued by him, this cooperation soon acquired a complex, systematic character and, ultimately, took a stable form of technology transfer. The work is based on the provisions of modernization theory, according to which technology transfer is considered as one of the key mechanisms of technological modernization of production. The scientific novelty of the study lies in the fact that no detailed research of historiography on the topic has been conducted to date. The author attempts to eliminate this obvious gap. In addition, one of the goals of this study is to promote the further development of the concept of technological transfer, which involves the transition to a systematic analysis of certain facts of scientific and technical cooperation of the USSR with foreign countries. The paper concludes that despite the extensive historiography on the topic, there are still numerous gaps that have yet to be filled by scientists. At the same time, at the current stage, of particular importance is not the search for factual material itself, which is already very extensive, but the reinterpretation of existing facts from the point of view of the provisions of the theory of modernization and the concept of technological transfer. This will make it possible to bring a systematic approach to the ongoing research on the topic and to make a comprehensive study of the state's scientific and technical policy in the first third of the XX century.
Radiative and Hydromagnetic Heat Transfer Analysis of a Reiner–Philippoff Fluid
Authors: Kumar Mahesh , Mondal Pranab Kumar
Published: August 2022

The aim of this work is to characterize the buoyancy-driven flow of a Reiner–Philippoff fluid over a vertical plate under the combined influences of a sinusoidal hydromagnetic effect and thermal radiation. This study focuses on the prediction of the conveyance of heat in the gravity-induced regime both qualitatively and quantitatively. Pertaining to this investigation, the governing transport equations, which are coupled, nonlinear, and time dependent, are solved numerically using a well-organized Crank–Nicolson scheme, consistent with the finite difference method. By demonstrating the graphical representations of flow velocity, temperature, drag coefficient, and heat transfer rate, obtained for a set of physical parameters, namely, magnetic parameter ([Formula: see text], 1.0, 1.5, and 2.0), rheological parameter ([Formula: see text], 1.0, 1.5, and 2.52), and radiation parameter ([Formula: see text], 1.5, 2.5, and 3.5) relevant to this analysis, this paper establishes their influence on the underlying thermohydrodynamics. The results of this analysis show that the impact of periodic magnetic field remarkably enhances the flowfield variables, while the evolution of flow contours deviates periodically with a higher amplitude when the magnitude of the periodic magnetic and thermal radiation parameters is increased. The results of this analysis seem to provide a basis for the design of a modern electromagnetic pump, largely used in applications of traditional energy resources.

Published: August 2022

Acute uterine emergencies constitute both obstetric and gynecologic conditions. The superior image resolution, superior soft-tissue characterization, and lack of ionizing radiation make magnetic resonance imaging (MRI) preferable over ultrasonography (USG) and computed tomography (CT) in investigating uterine emergencies. Although USG is the first-line imaging modality and is easily accessible, it has limitations. USG is an operator dependent and limited by patient factors such as obesity and muscle atrophy. CT is limited by its risk of teratogenicity in pregnant females, poor tissue differentiation, and radiation effect. The non-specific findings on CT may lead to misinterpretation of the pathology. MRI overcomes all these limitations and is emerging as the most crucial imaging modality in the emergency room (ER). The evolving 3D MR sequences further reduce the acquisition times, expanding its ER role. Although MRI is not the first-line imaging modality, it is a problem-solving tool when the ultrasound and CT are inconclusive. This pictorial review discusses the various MRI techniques used in uterine imaging and the appearances of distinct etiologies of uterine emergencies across different MRI sequences.
A Modular Polymer for Nanoparticle Supports

Published: August 2022

Nanoparticles are key to a range of applications, due to the properties that emerge as a result of their small size. However, their size also presents challenges to their processing and use, especially in relation to their immobilization on solid supports without losing their favourable functionalities. Here, we present a multifunctional polymer-bridge-based approach to attach a range of pre-synthesised nanoparticles onto microparticle supports. We demonstrate the attachment of mixtures of different types of metal-oxide nanoparticles, as well as metal-oxide nanoparticles modified with standard wet chemistry approaches. We then show that our method can also create composite films of metal and metal-oxide nanoparticles by exploiting different chemistries simultaneously. We finally apply our approach to the synthesis of designer microswimmers with decoupled mechanisms of steering (magnetic) and propulsion (light) via asymmetric nanoparticle binding, aka Toposelective Nanoparticle Attachment. We envision that the ability to freely mix available nanoparticles to produce composite films will help bridge the fields of catalysis, nanochemistry, and active matter towards new materials and applications.
Substrate Conformation Masquerades Two different Oxidants in Aromatic C-H and C-F bond activation by Heme-dependent Tyrosine Hydroxylase

Published: August 2022

A recently discovered heme-dependent enzyme TyrH offers a green approach for functionalizing the high-strength C-H and C-F bonds in aromatic compounds. However, there is ambiguity regarding the nature of intermediates (Cpd 0 or Cpd I) involved in activating these bonds. Herein, using comprehensive MD Simulations and hybrid QM/MM calculations, we reveal that it is Compound I (Cpd I) that acts as the primary oxidant involved in the functionalization of both the C-F and C-H bonds. Our study shows that the His88 close to the catalytic site acts as a modulator of aromaticity and is essential to initiate the C-H and C-F bond activation. The reaction proceeds via the proton abstraction from the 4-OH group of the substrate by His88, which is coupled with an electron transfer to form a single-electron reduced Cpd I-like intermediate. This species then inserts the oxygen atom into the sp3 hybridized C-H and C-F bond of the substrate. Interestingly, our mechanistic study shows that the two different conformations of the substrate are actually responsible for the C-F and C-H functionalization, which masquerades as two different characters of oxidants involved in the reaction.

Efficient methods for searching the chemical space of molecular compounds are needed to automate and accelerate the design of new functional molecules such as pharmaceuticals. Given the high cost in both resources and time for experimental efforts, computational approaches play a key role in guiding the selection of promising molecules for further investigation. Here, we construct a workflow to accelerate design by combining approximate quantum chemical methods [i.e. density-functional tight-binding (DFTB)], a graph convolutional neural network (GCNN) surrogate model for chemical property prediction, and a masked language model (MLM) for molecule generation. Property data from the DFTB calculations are used to train the surrogate model; the surrogate model is used to score candidates generated by the MLM. The surrogate reduces computation time by orders of magnitude compared to the DFTB calculations, enabling an increased search of chemical space. Furthermore, the MLM generates a diverse set of chemical modifications based on pre-training from a large compound library. We utilize the workflow to search for near-infrared photoactive molecules by minimizing the predicted HOMO-LUMO gap as the target property. Our results show that the workflow can generate optimized molecules outside of the original training set, which suggests that iterations of the workflow could be useful for searching vast chemical spaces in a wide range of design problems.

Published: August 2022

There is widespread interest in reaching the practical efficiency of cadmium telluride (CdTe) thin-film solar cells, which suffer from significant open-circuit voltage loss due to high surface recombination velocity and Schottky barrier at the back contact. Here, we focus on back contacts in the superstrate configuration with the goal of finding new materials, that can provide improved passivation, electron reflection and hole transport properties compared to the commonly used material, ZnTe. We performed a computational search among 229 binary and ternary tetrahedrally-bonded structures using first-principles methods and transport models to evaluate critical materials design criteria, including phase stability, electronic structure, hole transport, band alignments, and p-type dopability. Through this search, we have identified several candidate materials and their alloys (AlAs, AgAlTe2, ZnGeP2, ZnSiAs2, CuAlTe2) that exhibit promising properties for back contacts. We hope these new material recommendations and associated guidelines will inspire new directions in hole transport layer design for CdTe solar cells.

4-Membered ring heterocycles oxetanes and azetidines offer exciting potential as small polar molecular motifs in medicinal chemistry but require further methods for their incorporation. Photoredox catalysis has emerged as a powerful method for the mild generation of alkyl radicals for C–C bond-forming reactions. However, the reactivity of radicals on strained rings is not well understood and there are few studies that address this question systematically. Furthermore, examples that use tertiary and benzylic radicals are rare, and their reactivity is challenging to harness and direct towards productive reaction pathways. This work develops a radical functionalization of benzylic oxetanes and azetidines using visible light photoredox catalysis to prepare 3-aryl-3-alkyl substituted derivatives and assesses the influence of ring strain on the reactivity of medicinally important small-ring radicals. 3-Aryl-3-carboxylic acid oxetanes and azetidines are suitable precur- sors for the formation of tertiary benzylic oxetane/azetidine radicals with loss of CO2 and subsequent conjugate addition into activated alkenes. The process is shown to be tolerant of polar functional groups and heterocycles to generate medicinally relevant compounds bearing oxetane or azetidine motifs. We compare the reactivity of the oxetane radicals with that of other common benzylic systems. Computational studies indicate the Giese addition of benzylic radicals into acrylates to be generally reversible, resulting in lower yields and radical dimerization. However, the oxetane structure provides an overall exergonic process for the Giese addition step of the benzylic radical. Furthermore, strained ring structures benefit from lower spin density at the benzylic position, which is crucial to minimize radical dimerization. The lower spin density results from more extensive radical delocalization into the aromatic system which is rationalized on the basis of hybridization. The effect of radical acceptor on the distribution of products is investigated and a mechanism for the formation of side products of reduction is proposed based on experimental and computational evidence.
Visualizing Formation of High Entropy Alloy Nanoparticles by Aggregation of Amorphous Metal Cluster Intermediates

Published: August 2022

High entropy alloy (HEA) nanoparticles hold promise as active and durable (electro)catalysts. Understanding their formation mechanism will enable rational control over the atomic arrangement of multimetallic catalytic surface sites. While prior reports have attributed HEA nanoparticle formation to nucleation and growth, there is a dearth of detailed mechanistic investigations. Here we utilize transmission electron microscopy (TEM), systematic synthesis, and mass spectrometry (MS) to demonstrate that HEA nanoparticles form by aggregation of non-crystalline multimetallic cluster intermediates. AuAgCuPtPd HEA nanoparticles were synthesized by aqueous co-reduction of metal salts with sodium borohydride in the presence of thiolated polymer ligands. Varying the metal:ligand ratio during synthesis showed that alloyed HEA nanoparticles formed only above a threshold ligand concentration. Alloyed sub-nanometer clusters were observed with the final HEA nanoparticles while few clusters were observed when phase-separated nanoparticles formed. Increasing supersaturation ratio increased particle size, which together with the observations of stable single atoms smaller than the critical nuclei size was inconsistent with a burst nucleation mechanism. Direct real-time observations with liquid phase TEM imaging showed that HEA nanoparticles formed by aggregation of sub-nanometer clusters. Taken together, these results are consistent with a reaction mechanism involving rapid reduction of metal ions into sub-nanometer alloyed clusters, followed by cluster aggregation driven by borohydride ion induced thiol ligand desorption. This work suggests intermediate cluster species as potential synthetic handles for rational control over HEA nanoparticle atomic structure.

Published: August 2022

La formación por competencias implica un cambio en los modelos de educación tradicional, en donde se daba más importancia a la cantidad de temáticas abordadas en un plan de estudios que a su pertinencia y relación con la formación integral. Formar por competencias implica darle significado a los contenidos curriculares, entendiendo que el conocimiento no se debe quedar exclusivamente en las aulas de clases, sino que debe trascender para que sirva como herramienta en el planteamiento de soluciones en las organizaciones y la sociedad en general. Lo anterior se hace más evidente en los momentos actuales, cuando se habla de la Industria 4.0 no solo como una revolución de los sistemas productivos, sino además como una nueva manera de entender las relaciones laborales, los procesos de desarrollo económico y la forma como la educación superior tiene que adaptarse para formar profesionales acordes con la realidad. En el presente trabajo se pretende hacer una breve revisión teórica del concepto de competencia y la manera como la formación por competencias debiera se implementada en programas académicos como la Ingeniería Industrial, de forma que dicho proceso formativo genere como resultados profesionales idóneos para competir en un mundo globalizado y marcado por la velocidad de los avances tecnológicos. Para tal efecto se lleva a cabo una revisión de los conceptos de competencia y aprendizaje por competencias y su relación con la Industria 4.0. La metodología empleada tiene un enfoque mixto, de tipo descriptiva. Para la obtención de información secundaria se recurrió a bases de datos académicas y se construyó una matriz de revisión sistemática de literatura; para la información primaria se empleó como herramienta la encuesta aplicada a 22 empresas y 9 universidades de la ciudad de Medellín Los resultados parciales obtenidos muestran un comparativo entre la oferta educativa y las necesidades del sector productivo y social.
CARACTERIZACIÓN DE TIPOS DE PERSONALIDAD EN CURSOS DE INGENIERÍA QUE EVALÚAN TRABAJO EN EQUIPO EN LA JAVERIANA CALI

Published: August 2022

El trabajo en equipo es una característica inseparable de la práctica profesional de la ingeniería. En el contexto de la acreditación de ABET, el trabajo en equipo es una habilidad que deben desarrollar los estudiantes en su programa académico. En ese sentido, la evaluación de esta habilidad debe hacerse observando la forma como trabajan los equipos, cómo asignan roles, cumplen tareas y cronogramas, y cómo ejercen liderazgo y resuelven conflictos. Así, la formación de los equipos es fundamental para su funcionamiento. En los programas de Ingeniería Industrial e Ingeniería Civil de la Javeriana Cali se viene aplicando el Indicador de Tipos de Myers-Briggs (MBTI) para formar los equipos en los cursos que evalúan esa habilidad para ABET. Este trabajo reporta los hallazgos encontrados con este ejercicio en los años 2018 y 2019 en siete cursos de estos dos programas. Se encontró que en Ingeniería Industrial el tipo de personalidad prevalente fue extrovertido-observador-emocional-juzgador mientras que en Ingeniería Civil fue extrovertido-observador-pensador-juzgador. Esto sugiere que los métodos de enseñanza en estos programas deberían favorecer las actividades grupales, orientadas a lo práctico y concreto, con consideración por los demás y por la toma de decisiones lógicas, y desarrolladas en una estructura ordenada. Aunque el MBTI es reconocido en ingeniería, se recomienda el uso de otros indicadores como el KOLB que considera los estilos de aprendizaje.

Published: August 2022

The effect of various efficiency calibration approaches on the value and source of the HRGS measurement uncertainty of 234U/238U, 235U/238U, 234U/235U isotopic ratios for the purposes of technological control, nuclear forensics, and environmental monitoring has been studied. The Canberra Broad Energy Germanium detector BEGe3830 and five samples of uranium certified reference materials CRM 969 and CRM 146 with a content of 235U/U ranging from 0.7 to 20.0 wt. % have been used. To calculate the uranium isotope ratios, the acquired gamma spectra were processed using: commercial MGAU (LLNL), FRAM (LANL), ISOCS software (Canberra/Mirion Technologies), based on intrinsic and absolute efficiency calibration approaches. It has been found that maximum relative biases, for the 234U/238U and 234U/235U isotopic ratios determined using the MGAU \ FRAM \ ISOCS software, are ~ 25 % \ ~ 10 % \ ~ 10 %, and the random uncertainty is varied within ± [18-25 % \ 2-15 % \ <=3 %], respectively. In the case of 234U/238U isotopic ratio determination using the MGAU \ FRAM \ ISOCS software, maximum relative biases come to ~ 3 % \ ~ 4 % \ ~ 1 %, and the random uncertainty values decrease to ± [1 % \ 1 % \ 1 %], respectively. In the present paper, we propose a combined intrinsic efficiency calibration approach with the use of the polynomial functions for the analytical description of the relation εrel.i(Ei). In this approach maximum relative biases, in the determination of the 234U/238U and 234U/235U isotopic ratios is 2.7 % at a random uncertainty of <= 1 %, and in the case of the 234U/238U ratio a maximum relative deviation is 0.5 % at a random uncertainty of <= 0.7 %.
The effect of different types of nasal tamponades in patients with nasal bleeding on mucociliary transport of the mucous membrane
Authors: Bychkova Nataliia
Published: August 2022

Introduction. The number of patients with nasal bleedings (NB) remains quite high (14.7–20.5 %) among all patients in need of emergency ENT care. When using anticoagulants and disaggregants, the risk of developing hemorrhagic complications is always higher. Otorhinolaryngologists have been improving the methods of stopping NC for many years. Objective: a comparative study of the effect of different types of nasal tamponade on mucociliary transport (MCT) of the nasal mucosa in patients with NB on the background of antithrombotic therapy. Materials and methods. The effect of different types of nasal tamponade on MCT of the nasal mucosa in 156 patients with NC who developed on the background of antithrombotic therapy was studied. All patients were divided into two groups: the main (104 patients), in which NB cessation was performed by the combined method, which includes the use of a two-chamber hydraulic tampon of our own design in combination with Nosochem gel and thermal exposure, and the control group (52 patients), where the classic gauze tamponade was used. The criterion for assessing the functional state of the nasal mucosa was the time of MCT when performing the saccharin test. Results. Immediately after removal of tampons, a significant acceleration of the MCT rate was observed in patients of both groups in comparison with the conditional norm. On day 3 after tampon removal, a significant decrease in the rate of MCT was observed in both study groups, which was more significantly (p <0.001) expressed in patients with traditional gauze tamponade. The MCT time indicator in the patients of the main group exceeded the level of the conditional norm by 36.9 %, and the similar indicator of the control group by 55.1 %. On day 7 after hydrotampon removal, time recovery was observed in patients of the main group. In patients of the control group on day 7 of gauze tampon removal there was a tendency to increase the rate of MCT. On day 14 after removal of tampons, the MCT rate in patients of the main group remained within the conditional norm, and the level of MCT rate in patients of the control group approached the conditional norm. Conclusions. Mechanical tamponade causes a violation of the functional state of the ciliated epithelium of the nasal mucosa, causing significant activation of MCT after removal of tampons, followed by a slowing of the MCT rate. Hydroballoon tamponade causes less expressed changes in MCT with a faster recovery period of the transport function of the ciliated epithelium compared to traditional gauze tamponade, what indicates a more gentle effect on the mucous membrane of the nasal cavity.

Published: August 2022

Objetivo.

Estudiar la repercusión de la pandemia de COVID-19 en el acceso a la atención del cáncer en Chile, analizando los efectos diferenciales por tipo de seguro, sexo y edad.

Métodos.

Se llevó a cabo un estudio cuasiexperimental mediante análisis de series temporales interrumpidas. Se recurrió a fuentes de datos múltiples con el fin de lograr una evaluación amplia de la utilización de la atención del cáncer de enero del 2017 a diciembre del 2020. Se ajustaron modelos binomiales negativos en función de los grupos de población para una diversidad de servicios y diagnósticos.

Resultados.

Tras una disminución considerable de la utilización de la atención oncológica en marzo, se observó una recuperación lenta e incompleta durante el 2020. Los servicios de atención del cáncer, las confirmaciones diagnósticas y las licencias por enfermedad acumulados se redujeron en un tercio en el 2020; la disminución fue más pronunciada en las mujeres y las personas afiliadas al seguro de enfermedad público. No se hizo un diagnóstico temprano en 5132 personas con cuatro tipos frecuentes de cáncer.

Conclusiones.

La pandemia sobrecargó el sistema de salud chileno y provocó una disminución del acceso a los servicios básicos, con una repercusión profunda en la atención del cáncer. La reducción de los servicios de oncología precedió los confinamientos a gran escala y las interrupciones por parte de los prestadores. Cabe destacar que no todos los grupos de la población se vieron afectados por igual y se observaron pautas que indican un agravamiento de las desigualdades por situación socioeconómica y sexo.

Las afecciones de salud mental tienen una prevalencia sumamente alta en los trabajadores de salud de Guatemala.
"Each Council shall appoint a competent person for the borough, hereinafter called "Inspector of Buildings"": The development of building controls in the second decade of the twentieth century
Authors: Isaacs Nigel
Published: August 2022

In 1903 the first edition of the Municipal Handbook of New Zealand was released by the Census and Statistics Office. From then on published biennially, it provided detailed statistical and administrative information on each borough, city, independent town district, and harbour board. This included a brief statistical summary with details of the various activities as well as the names of "Chief Officials," including those responsible for buildings. These included engineers (e.g. Borough Engineer), inspectors (e.g. Building Inspector) and surveyors (e.g. Building Surveyor). From 1910 the numbers of these officials increased, suggesting a growing interest in building controls. The 1915 edition of the Handbook listed 176 municipalities, of which 44 (25%) listed a chief official with a role related to buildings. These included 35 engineers, eight inspectors and one surveyor. The paper explores, based on the Municipal Handbook series, the changing interest of New Zealand local government in the buildings constructed within their boundaries in the second decade of the twentieth century.
Rethinking Te Aro in the 1910s
Authors: Jacob James
Published: August 2022

Wellington's Te Aro neighbourhood is particularly notable for both its broad expanse of relatively flat land and for its rectilinear grid of streets and associated superblocks in a city otherwise known for its hills and irregular road system. Over the course of the nineteenth-century after the start of European settlement in 1840, the town acres within the superblocks of Te Aro were more intensively developed in myriad ways, resulting in a haphazard arrangement of worker dwellings, commercial premises, and industrial outfits aligned along largely private lanes and alleys. With the notable exception of the street grid, nearly all vestiges of this initial, Victorian-era development were progressively destroyed during the twentieth century.

Although most of the architectural and urban reinvention of Te Aro did not occur until the decades following World War II, acknowledgment of the major factors that would ultimately contribute to this process - traffic congestion, the low quality of the existing building stock, and a strong shift away from residential functions - became more and more emphasised during the 1910s. A writer for the Evening Post in 1913 imagined the neighbourhood just seven years in the future: "the dingy wooden boxes on Te Aro Flat will have given place to handsome warehouses and shops and factories …The problem of traffic, already threatening trouble … is certainly a task for the ablest engineer nowadays to suggest a way out" (Autos "The Future" p 3). This degree of optimism for rapid change was quickly tempered by the realities of world war and, in retrospect, the 1910s can be interpreted as a period of incubation for ideas about architecture urban planning in Te Aro that would only come to fruition later in the century.
Noel Bamford: the first director of the Auckland School of Architecture
Authors: Tyler Linda
Published: August 2022

Auckland's keenest advocate of the Arts and Crafts movement was Frederick Noel Bamford (1881-1952) who was the first director of the Auckland School of Architecture from 1917-19. Apprenticed to carpenter and architect Edward Bartley (1839-1919) during the years that St Matthews-in-the-city was being designed, Bamford excelled at drawing and travelled to London to become a student at the Royal Institute of British Architects' School in 1904. Along with fellow expatriate architectural student Arthur Patrick Hector Pierce (1879-1918), Bamford found work in the office of Edwin Lutyens (1869-1919), famed for his romantic English country houses. Bamford returned to Auckland in 1906, and was elected an Associate of the RIBA the following year. Pierce followed, and they formed an architectural partnership which became renowned for its houses in the English Domestic Revival style adapted for New Zealand conditions. Bamford and Pierce are best known for designing the glamourous Coolangatta, 464 Remuera Road (1911, demolished in 2006) for Canadian-born Alfred Foster, a surveyor and his wife Jessie, which Peter Shaw observes is almost an exact copy of a Lutyens house at Fulbrook, Elstead, Surrey, built in 1897. As well as indicating the rapid transmission the Lutyens country house typology to New Zealand, the story of the Bamford and Pierce partnership offers an intriguing insight into the social relationships of Edwardian Auckland. Pierce's father George was prominent in the Anglican Diocese, and one of the earliest commissions that Bamford and Pierce secured was for Bishopscourt, a home for the Anglican Bishop of Auckland, known as Neligan House (1909-10). Connections to the law firm of Hesketh Richmond (Bamford's father was Edwin Bamford, (1846-1928), Registrar-General of Lands) resulted in the commission for Waione (1910), a single storey house at 22 Domett Avenue, Epsom as well as two houses for wealthy heiress Jeannie Stirling Richmond (1854-1917) for construction on her Rockwood estate. Ngahere at 74 Mountain Road (1907-8) was designed for Richmond's newly married daughter Margaret MacCormick (1884-1972) is renowned for its butterfly floor plan. Woodend at Gilgit Road (circa 1914-15) was designed as the home of Noel Bamford's brother, lawyer Dr Harry Dean Bamford, who lectured in law at Auckland University College. In 1912, the year that his Remuera house went up in flames destroying £2000 worth of Arts and Crafts furniture, Bamford founded the Arts and Crafts Club in Auckland, becoming its inaugural president. The Club was to have a key role in promoting the adaptation of the ideology of William Morris, and incorporated Māori arts into its definition of craft.
High-Performance Homes In New Zealand A Survey On The Influence Of The User Behaviour And Its Effects
Authors:   , Brougham-Romney Paolina
Published: August 2022

The number of High-Performance houses in New Zealand has been increasing since the first Homestar rated home was built in 2012. Certified High-Performance Homes can be certified as either Passive House, Homestar, Superhome, or built to a higher standard than what the New Zealand Building Code requires, but not rated under a scheme. Passive House seeks for the house to be thermally comfortable all year round. Homestar seeks an overall sustainable approach, including construction waste and water use, but other factors can help the rating. Finally, the Superhome Movement focuses on a healthy home and design quality. Historically, New Zealand homes built to earlier versions of the New Zealand Building Code were typically cold, draughty and damp. Household Energy End-use Project (HEEP) by Isaacs et al. in 2010 found that the average temperatures in homes were typically around 14°C, consistent with how New Zealand homes are heated, by heating the living room a few hours every evening. The households who participated in this research are not consistent with the New Zealand housing stock as they have exceeded the minimum requirements of the New Zealand Building Code. This paper aimed to explore what the designers and users expected from their High-Performance houses and if their understanding of it influenced the performance of the house. Designers and house occupiers of 9 High-Performance houses were interviewed and asked questions regarding their house's functionality and behaviour. All the participating houses have a mechanical ventilation unit, double or triple glazed windows, as well as higher insulation in walls, roofs and subfloor than required in the New Zealand Building Code. Photovoltaic Panels were present in 4 of the participating houses, 2 of these houses had energy storage systems that allowed the users to store excess harvested energy from the panels. 46% of the participants installed additional building services after occupancy, with a space heater being the most common addition. The results where positive; most of the occupiers where able to maximise their house performance potentials and all the participants understood the systems their house had. The primary motivation of the participants was to build a healthy and thermally comfortable house. All the participants would build a High-Performance house again if given the opportunity. A Design Guide was formulated for future build commissioners and designers to recommend specification solutions to achieve a High-Performance house. Currently, all the participating homeowners have the knowledge to potentialize their house efficiency, as they were the commissioners. In the future, this might shift once more High-Performance houses get introduced into the New Zealand housing stock.

The placebo effect can be explained as a response other than the specific influence of a treatment which comes from the psychosocial forces surrounding the treatment. This effect can be observed all over the world when people use healing stones. In this study, the perception of healing stones was investigated using the questionnaire technique. A popular online site helped reach 415 volunteers who participated in an online survey. Evaluation of the results revealed that gemstones, which are promoted as healing tools and give hope for getting better, have a positive ef-fect on people. On the other hand, even if gemstones are preferred only for use as ornamental stones, jewelry and accessories, then no positive effect is expected from their healing power.
AN ANALYSIS OF ABSTRACT USING MOVE MODEL ON HYLAND’S THEORY IN PROJECT JOURNAL ARTICLE
Authors: Mu'man Mu'man
Published: August 2022

An abstract is one of the important parts in a research paper. It must give detail information to the readers. This research aimed to analyze abstracts’ content by using Move model proposed by Hyland (2003). It consists of introduction, purpose, method, result or product, and conclusion.  This research used a qualitative method which specifically used content analysis design. Content analysis design was used because the researcher analyzed the content of abstracts taken from PROJECT Journal article which meant whether the writers presented the detail information as Move model or not. Evidently, from 15 articles analyzed, it was only one person who displayed detail information which was appropriate with Move model and the others were still not what the researcher expected except in informing the methods used. From the result of analysis, the understanding of writers about giving detail information in an abstract still lacks. It proves that the data finding presented in the result showed the weakness of abstracts which were not suitable yet with Move model.

What are the students' news writing challenges in the fourth semester of Grade E, according to this study's major issue? And what are the cognitive process-based characteristics that affect the students' difficulty with news writing in the fourth semester of grade E? The goal was to determine the students' news writing challenges in the fourth semester of Grade E and the factors affecting those challenges based on the students' cognitive processes at that time. The focus of the study was the fourth semester's twenty-two student population. The Qualitative Research Method was employed in this study. The information was acquired through observation, document (news articles written by students), and interview. The results demonstrated that there are two categories of students who have trouble pre-writing and pre-drafting a news article. The outcome showed there are nine students.
The Design of Multimedia in Storytelling

Published: August 2022

Learning and teaching a foreign language needs a lot of patience, energy, time, creativity, and competence. The success of the teaching and learning of foreign language skills including English is determined by several factors such as students, teachers, teaching methods, techniques, and instructional Multimedia. English teaching Multimedia is very important for the teacher to help students acquire a new concept of the skills and language competencies. This study made use of the qualitative method. The researcher used Educational Research and Development cycle from Borg and Gall (2007) which is adjusted into five steps, namely (1) research and information gathering, (2) planning, (3) preliminary product development, (4) preliminary field testing, and (5) primary product revision. There are still many fascinating discussions that might be interesting to find out the real situation in the implementation of Multimedia in English language teaching, especially in storytelling. This study which was conducted by the students of SMK Mitra Karya Mandiri Ketanggungan-Brebes is intended to figure out how the use of Multimedia in English language teaching to the first levels. The study employed a case study research design. The researcher collected the literature review, distributed questionnaires to the students, and interviewed one of the English teachers. After collecting the literature review, the researcher first distributed the questionnaires to the students. The respondents to the questionnaires were 30 students. The result of the research shows that digital storytelling can be built up to teach narrative. The purpose of the medium must be communicative and attractive to the students. Equally, for the students, they are interested in using digital storytelling to learn about narrative. Hence, digital storytelling is designed to help students in all competencies, such as reading, speaking, listening, writing, and the vocabulary teaching-learning process.

Published: August 2022

Conventional transbronchial needle aspiration (cTBNA) biopsy is a diagnostic minimally invasive technique applied using fibreoptic bronchoscopy (FOB) in the evaluation of mediastinal/hilar lymph nodes. With the development of endobronchial ultrasound (EBUS) devices, transbronchial aspiration needles have been revised for use according to the EBUS guidelines. The main aim of this research was to evaluate the diagnostic success of transbronchial aspiration needles that was produced for EBUS when it was applied with FOB instead of conventional TBNA. A retrospective examination was made with the data of 35 patients applied with FOB TBNA, using needles specifically designed for EBUS and 36 patients with conventional TBNA (cTBNA group), for lung cancer staging or the diagnosis of mediastinal lymphadenopathy between November 2018 and November 2019. Seventy-two and sixty procedures performed on 71 patients were included in the study. Diagnostic efficiency for TBNA and cTBNA groups were 91.4% and 83.3%, respectively. Conventional TBNA is still acceptable when the low cost and ease of application are taken into consideration. In conclusion, improvement of current conventional TBNA needles similar to EBUS-TBNA needles for more efficient aspiration capacity could be the first stepto increasing the TBNA diagnostic yield. Nevertheless, further studies are needed to confirm our results.

Published: August 2022

Emotion recognition systems (ERS) have become a popular research field to contribute to human-machine interaction in different areas. Different kinds of applications on ERS can serve different purposes. Artificial intelligence (AI) and the internet of things (IoT) are the technologies behind such applications. The main objective of this study is to enable researchers and developers to search for the most suitable options to develop an emotional state recognition system. More specifically, this paper presents work on ERS, which is built using physiological signals extracted from biosensors. It also presents details of how the extracted physiological signals are used to identify the user's emotional state. In this review, the sensors are categorized based on their modality: contact-based sensors and contactless sensors. Next, the ERS process is presented together with the reported results for each described technique. Articles from four different research databases were reviewed, of which 147 articles from 2009 to 2021 were referred to that are related to ERS using physiological signals. This paper should be significant for researchers developing systems that integrate human emotion recognition capability. The findings reported here can guide them in choosing suitable methods for their systems. Doi: 10.28991/ESJ-2022-06-05-017 Full Text: PDF
