Published: December 2022

This paper presents an advanced borehole heat exchanger that has been developed in order to apply a ground source heat pump to a volcanic island where the existing borehole heat exchangers are inapplicable by local ordinance. The advanced borehole heat exchanger was fabricated and installed at a verification-test site to evaluate its heat capacity in terms of refrigeration ton (RT). The proposed heat exchanger was also compared with the conventional heat exchanger that was made of high-density polyethylene (HDPE) heat exchanger. The thermal response test was carried out by flowing water at various temperatures into the heat exchangers at the fixed flow rate of 180 L/min. The results revealed that the maximum heat capacity for the developed heat exchanger was measured at 63.9 kW, which is 160% higher than that of the high-density polyethylene heat exchanger (39.9 kW). It was also found that the developed HX has the highest heat gain achieving 94 kW as compare to 21 kW for high-density polyethylene-Hx.

IntroductionTo develop and validate a radiogenomics model for predicting axillary lymph node metastasis (ALNM) in breast cancer compared to a genomics and radiomics model.MethodsThis retrospective study integrated transcriptomic data from The Cancer Genome Atlas with matched MRI data from The Cancer Imaging Archive for the same set of 111 patients with breast cancer, which were used as the training and testing groups. Fifteen patients from one hospital were enrolled as the external validation group. Radiomics features were extracted from dynamic contrast-enhanced (DCE)-MRI of breast cancer, and genomics features were derived from differentially expressed gene analysis of transcriptome data. Boruta was used for genomics and radiomics data dimension reduction and feature selection. Logistic regression was applied to develop genomics, radiomics, and radiogenomics models to predict ALNM. The performance of the three models was assessed by receiver operating characteristic curves and compared by the Delong test.ResultsThe genomics model was established by nine genomics features, and the radiomics model was established by three radiomics features. The two models showed good discrimination performance in predicting ALNM in breast cancer, with areas under the curves (AUCs) of 0.80, 0.67, and 0.52 for the genomics model and 0.72, 0.68, and 0.71 for the radiomics model in the training, testing and external validation groups, respectively. The radiogenomics model integrated with five genomics features and three radiomics features had a better performance, with AUCs of 0.84, 0.75, and 0.82 in the three groups, respectively, which was higher than the AUC of the radiomics model in the training group and the genomics model in the external validation group (both P &lt; 0.05).ConclusionThe radiogenomics model combining radiomics features and genomics features improved the performance to predict ALNM in breast cancer.

Published: December 2022

CP fandom behaviors or shipping, a growing popular phenomenon among Chinese young adults, refers to the activities of fans who take great satisfaction from the romantic relationships and interactions of their preferred pairings of idols or virtual characters. CP fans are regarded as a special group of fans with unique identities and interaction styles. This grounded theory study was conducted to explore the mechanism of CP fandom behaviors. Semi-structured in-depth interviews were conducted with thirty-one Chinese CP fans (twenty-eight females and three males). The antecedents, development, behavioral patterns, and consequences of shipping were identified in a comprehensive model. The reasons for CP fandom behaviors include individual factors (e.g., psychological projection, compensation, and social needs) and external factors (e.g., pop culture and internet environment). The consequences include positive emotional experiences, changed love values, and improved social interaction. CP fandom behaviors can be different in terms of the fans’ degrees of engagement, and the development of shipping can be divided into three stages: exploratory stage, formation and stability stage, and rupture stage. This study contributes to the literature of CP fandom behaviors among young adults in China and proposes the directions of future studies on such topics.

This study determined the influences of Bacillus sphaericus Laboratorium voor Microbiologie Gent (LMG) 22257 bacteria activity on mortar samples cured in various media regarding compressive strength, porosity, water absorption, and water permeability. Three types of curing media were utilized, namely distilled water (D.W.), deposition water (D.M.), and run-off water (R.W.). The compressive strength was measured using 100 mm mortar cubes. The water porosity, water absorption, and water permeability were analyzed using the Leeds permeability cell with dimensions of the mortar cylindrical specimens of 55 mm diameter and 40 mm thickness. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectrometry (EDX) were utilized, respectively, for microstructure analysis and quantifying the elements with atomic numbers. The results indicated the presence of calcium carbonate and more calcium silicate hydrate (CSH) depositions on bacterial mortars. The inclusion of Bacillus sphaericus LMG 22257 bacteria activity and curing media type affected mortar properties through compressive strength and durability improvements, as well as the reduction in water porosity, water absorption, and water permeability of mortar. The comparison of CaCO3 precipitation, such as a sufficient growth nutrient requirement and hostile bacteria environment, was observed. Curing in R.W. produced the most significant bio-based cement (BBC) mortar improvement, followed by D.M. BBC curing in runoff water had a 40% improvement in strength compared to normal curing. As a conclusion, runoff water is a highly promising sufficient nutrient to bacteria for the biomineralization process to produce CaCO3. This work also aims to apply this approach in the field, especially in sewerage and drainage systems.

Este artículo analiza la contribución de las universidades y escuelas de negocios católicas dentro del contexto latinoamericano, a través de lo que estas consideran relevante sobre el desarrollo de competencias de sus estudiantes. Por medio del estudio de casos, se analizaron las visiones y misiones de estas instituciones y se identificaron y compararon las competencias de conocimientos, habilidades y actitudes que más desarrollan las universidades y escuelas de negocios, tanto católicas como no católicas. Se observó que en las instituciones no católicas las competencias más relevantes son el conocimiento y las habilidades, mientras que en las católicas se fomenta igualmente el conocimiento, pero más que las habilidades, se enfatiza en las actitudes. En el estudio realizado no se encontraron diferencias mayores entre Perú y el resto de países latinoamericanos.
El desarrollo de las actitudes es fundamental para generar un cambio, que implique una disposición continua de la persona; estableciendo relaciones con otras, que no necesariamente piensen igual. El rol de las universidades y escuelas de negocios católicas consiste en enfatizar aquellas competencias que permitan que los líderes que forman puedan generar esos cambios que el panorama actual y futuro requieren.

La crisis sanitaria por el covid-19 dejó un gran desafío en relación con el bienestar emocional de los niños, tanto para padres de familia como para las escuelas. En este sentido, se busca integrarlos nuevamente a un contexto real, recuperando lo que se había suspendido: el derecho a la salud, educación, contacto con la naturaleza, el juego espontáneo, libre de miedo por el contagio y la experimentación de emociones positivas; propias del afecto y la socialización.
La inteligencia emocional es fundamental en el ser humano porque le garantiza un estilo de vida pleno y saludable por eso el objetivo de esta investigación es analizar el impacto de los ambientes naturales en la educación emocional de los niños, sobre todo después de un contexto de pandemia. El resultado obtenido comprueba que, a lo largo de la historia, el medio natural contribuye al desarrollo cognitivo y emocional; por tal motivo en la actualidad se ha elaborado el modelo psicopedagógico de las cinco competencias socioemocionales que promueve la educación emocional desde las escuelas a través de actividades lúdicas en ambientes naturales, lo que favorece al desarrollo de estas competencias y de vínculos interpersonales favorables en los niños.
ПИТАЛЬНІ РЕЧЕННЯ ЯК ЗАСІБ ВПЛИВУ НА АДРЕСАТА В ПРОПОВІДЯХ ПОЛЬСЬКОГО БАРОКОВОГО ПРОПОВІДНИКА ТОМАША МЛОДЗЯНОВСЬКОГО
Authors: Зелінська Оксана 
Published: December 2022

У статті проаналізовано специфіку використання питальних речень у проповідях Томаша Млодзяновського, видатного польського проповідника епохи Бароко.
Проаналізовані тексти проповідей Т. Млодзяновського засвідчують, що автор використовував питальні конструкції як засіб впливу на адресатів. Питальні речення в монологічному мовленні проповідника виконують вторинні функції, спрямовані не на отримання, а на передачу інформації.
Незважаючи на те, що формально вони є запитаннями, комунікативною метою їх є не запит інформації та спонукання адресата до відповіді, а залучення його уваги до інформації, яку передає мовець. Конструкції, побудовані як питання-відповідь, є засобом діалогізації авторського мовлення. Діалогізація тексту сприяє встановленню контакту, змушує адресатів брати участь у пошуках відповідей, що створює атмосферу співпраці під час проповідування, створює ілюзію двобічної комунікації. Передусім питальні конструкції в проповідях сприяють активізації уваги аудиторії. Т. Млодзяновський продуктивно вживає катехетичні питання, які є основним засобом тлумачення правд віри, богословських понять, за їхньою допомогою розкриває символічні значення євангельських образів; комплекс питання – відповідь активно використовує для викриття неправдивості чужої віри та обстоювання правдивості віри католицької.
Питання слугують засобом логічної аргументації, шо посилює переконувальний вплив. Значна частина таких речень є засобом вираження волевиявлення проповідника: відповідь, котру автор проповіді дає на питання, є зазвичай прикладом, який треба наслідувати, чимало питальних речень мають мету запобігти грішним учинкам, уникнути небажаних для християнина ситуацій.

The purpose of the study was to analyze the website of a selected university in terms of usability and accessibility of user interfaces with particular attention to the guidelines of the Web Content Accessibility Guidelines (WCAG) standard. After taking into account all the guidelines, an improved version of the site was created that was free of the diagnosed errors and incompatibilities. Both sites were surveyed using the questionnaire method with the LUT checklist. A survey was also conducted using an eyetracker. Twenty participants took part in this study. The third method of evaluation was to analyze the sites using an automated tool - the WAVE plugin attached to a web browser. The data obtained from the research experiment were analyzed qualitatively and quantitatively. In case of the survey and the WAVE tool, only quantitative analysis was carried out. The results of the analyses carried out using the three methods show unequivocally that the author's website prepared by the authors is clearly better in terms of usability and accessibility than the website of the selected university.
Metaphorization of Emotions in German Football Fans’ Discourse
Authors: Belyutin Roman 
Published: December 2022

The article considers peculiarities of verbalization of emotions in German football fans’ discourse. Social, psychological, biological relevance of emotions in a person’s world view provides vivid interest of specialists, including linguists, in studying language means to objectify emotional concepts. Despite the fact that
the range of the studied aspects is urgent and is thoroughly examined, certain communicative domains organized by sports fans remain insufficiently explored, although according to some scientists, it is their subculture that is characterized by distinctive emotional background, «emotionally tense» attitude to events, phenomena, facts, people being under their magnifying glass.
The article provides cases of verbalization of emotions through metaphoric descriptions. The most active source domains are determined that represent emotional concepts (war, colour, nature, equipment, space, etc.), their direc-
tion vectors are identified, as well s objects and situations inducing emotions in a fans’ community. It can be considered productive for the futher study to analyze
linguistic (metaphoric) conceptualization of emotions in football fans’ discourse in different ethnic and language cultures to elicit national character in building metaphoric patterns of people’s emotional sphere. The article makes use of discourse, component and conceptual analysis, building metaphoric patterns, clas-
sification, lexicographical and comparative methods.
Reports of the Authorized Council for the Affairs of the Russian Orthodox Church in Moscow and the Moscow Region as a Source of Information about Parish Life in the Moscow Diocese in the 1944–1946
Authors: Nikonov Vadim 
Published: December 2022

The article analyzes information about the parish life of Moscow and the Moscow region churches in the 1944–1946 contained in the reports of the Commissioner for Moscow and the Moscow region of the Council for the Affairs of the Russian Orthodox Church made by A.A. Trushin according to the funds of the
Central State Archive of the Moscow region. The paper provides data on the number of churches operating in the first post-war years, as well as on how many churches closed in the 1920s and 1930s were used for economic and cultural
needs, which, according to the author, in most cases, contributed to their preservation until the period of mass transfer to the Church. To analyze the changes in the manifestations of popular religiosity in the mid-1940s, information on the attendance of Easter services is taken as a basis,
participation in which is considered as an open manifestation by believers of their attitude to the Church. These materials record a steady increase in the number of parishioners during the period under review, not only in Moscow, but also in cit-
ies near Moscow and rural parishes of remote areas – Taldomsky, Lukhovitsky, etc. The main reasons for the rise of popular religiosity, according to the author,
were the victory in the Great Patriotic War, as well as the expectations of changes in anti-church policy on the part of the state in the USSR that appeared after the
meeting of I.V. Stalin with the metropolitans of the Russian Orthodox Church in September 1943. The great interest in the array of documents under consideration
is represented by the data on the percentage of young people in the total number of believers and military personnel in the temples
