Authors: Nurohman Dede , Sari Nadia Roosmalita , Himmati Risdiana , Mas'ud Riduan
Published: February 2023

Religious tourism has become a trend nowadays. In Indonesia, religious tourism is dominated by Hajj and Umrah departures. Every year, the increasing demand for Hajj and Umrah services makes Hajj and Umrah travel agents emerge, both legal and illegal, and compete. Several strategies are implemented to capture this huge market opportunity. This has implications for the blurring of the spiritual dimension of worship itself. This paper reveals how the religious travel industry influences society and its impact on people's religious attitude. This study explores data through in-depth interviews with travel agency managers, KBIHU (Hajj & Umrah Guidance Group), and pilgrims and conducting document studies from these institutions in direct written form or through electronic media. This study finds that the travel agents’ ways of business in attracting the pilgrims are through internal strategies such as package and price variations, and also by external methods to establish partnerships with KBIHU, individual agents, and public figures. Practical implications and Originality/value-These ways of business impact the religious attitude of Muslims, which are consumptive and profane. This research results can be used as material for evaluating the implementation of Hajj and Umrah trips, both by the government, travel agencies, and prospective pilgrims. This is a pioneer empirical study that focuses on religious tourism and religious attitude of Indonesian muslims.

Published: February 2023

El presente artículo tiene como objetivo visualizar la importancia de uno de los elementos que influyen en la internalización de las organizaciones, es decir, de la cultura como un elemento general. Mediante la interculturalidad, se realiza una interacción entre diversas culturas que influyen de manera externa en el entorno de las empresas, pero que también guardan relación con el entorno interno a través de la cultura organizacional; el conocimiento y manejo de los elementos como es la cultura, permite a las organizaciones contar con capacidades interculturales que se convierten en ventajas competitivas las cuales beneficia la estrategia y gestión de las mismas. Se parte de la pregunta ¿Por qué se puede considerar una ventaja competitiva el control y manejo de elemento cultural en la internalización de las organizaciones?, se analizará de manera cualitativa las tres posturas más representativas de la relación entre la interculturalidad y la organización. Esta investigación tiene como limitante el panorama general y no aborda las particularidades de otros elementos que pudieran llegar a converger.

Published: February 2023

En comparación con otros rubros de la economía, el desarrollo de la industria aeroespacial en México es prácticamente reciente, de ahí que su estudio y análisis es muy necesario para comprobar la evolución que ha tenido, así como las propuestas que siguen surgiendo para aprovechar el dinamismo y crecimiento que ha presentado desde inicios del siglo XXI. Por otro lado, las condiciones económicas en México han impulsado la creación de micro, pequeñas y medianas empresas (mipymes) en todas las áreas productivas, una de las cuales es la industria aeroespacial. Debido a ello, ha sido imperativo para el gobierno mexicano establecer la normatividad necesaria para la conformación, regulación y perfeccionamiento de las estrategias comerciales en materia aeroespacial, con el fin de asegurar su funcionamiento conforme lo exigen las normas internacionales. A través de un cuadro de generador de valor sustentable, se emplea un análisis para establecer un plan de acción con base en los lineamientos nacionales e internacional en relación con la situación de las mipymes mexicanas en el sector aeroespacial. Este trabajo describe un enfoque para que las mipymes mexicanas de este sector económico tengan una mayor visión de las características sobre estrategias sustentables para una mayor competitividad y generar valor sustentable. De esta manera, se establece una ponderación basada en TOPSIS Fuzzy para establecer las estrategias sustentables adecuadas para alcanzar los objetivos esperados en los lineamientos de la industria aeroespacial en México.

 

Compared to other areas of the economy, the development of the aerospace industry in Mexico is recent, hence its study and analysis is very necessary to verify the evolution it has had, as well as the proposals that continue to emerge to take advantage of the dynamism and growth that it has presented since the beginning of the 21st century. On the other hand, economic conditions in Mexico have promoted the creation of micro, small and medium-sized enterprises (MSMEs) in all productive areas, one of which is the aerospace industry, which is why it has been imperative for the Mexican government to establish regulations necessary for the conformation, regulation, and improvement of commercial strategies in aerospace, in order to ensure its operation as required by international standards. Through a sustainable value generator chart, an analysis is used to establish an action plan based on national and international guidelines concerning the situation of Mexican MSMEs in the aerospace sector. This work describes an approach for Mexican MSMEs in this economic sector to have a more excellent vision of the characteristics of sustainable strategies for greater competitiveness. In this way, a weighting based on TOPSIS Fuzzy is established to establish the appropriate sustainable strategies to achieve the objectives expected in the guidelines of the aerospace industry in Mexico.

Authors: AKER Yusuf , KARAVARDAR Alper
Published: February 2023

Financial distress has become one of the main topics on which lots of research has been done in the recent finance literature. This paper aims to predict the financial distress of Turkish small and medium firms using Logistic Regression, Decision Tree, Random Forest, Support Vector Machines, K-Nearest Neighbor and Naive Bayes model. Empirical results indicate that decision tree model is the best classifier with overall accuracy of %90 and %97 respectively for 1 and 2 years prior to financial distress. Three years prior to financial distress, Naive Bayes outperform other models with an overall accuracy of 92.86%. Furthermore, this study finds that distressed firms have more bank loans and lower equity. In the Turkish economy, where cyclical fluctuations are high in the last decade, distressed firms grew rapidly with high bank loans and gained higher operating profits than non-distressed firms. After a while, distressed firms that cannot manage their financial expenses get into financial trouble and go bankrupt. This article can be useful for managers, investors and creditors as well as its contribution to academic research.
Relativity Approach to the Strategic Cyber Conflict Management in Businesses
Authors: ÖZSUNGUR Fahri
Published: February 2023

Purpose: The study aims to form a theoretical basis for the development of strategies needed by businesses and establish strategic principles. The starting point of this research is that cyber conflict is an operational, managerial, relational, and strategic problem of businesses rather than a cross-country administrative problem.

Design/methodology/approach: This research was carried out by adopting grounded theory, known as theorizing-based theory. The study was carried out with 593 limited liability and joint-stock companies operating in Turkey.

Findings: The research results revealed a new theory named "relativity of strategic cyber conflict management". According to the research findings, the five orbital forces (negotiation, managerial, infrastructure, defense, competition) were determined in cyber conflict management. Four principles were determined as a business within the system (location in space), the business within cyber cosmos (relativity of time), warping spacetime due to cyber conflict (Curvature of strategy), and illusions due to cyber conflict (Gravitational lenses).

Originality: This study introduces a new theory of the cyber conflict management with the inspiration of the principles of relativity theory.

Published: February 2023

Energy is an important input for production, growth, and development. A sustainable energy sector, where energy production and consumption balance is ensured, constitutes a key point for nature and humanity. In this study, a multidimensional framework is presented to measure corporate sustainability in the energy sector. Based on this framework, the sustainability performance of energy companies operating in the Asia and Europe regions is measured by hybrid multiple-criteria decision-making (MCDM) methods, taking into account the economic, environmental, and social dimensions of sustainability. The Entropy method is used to determine the weights of the criteria, the Proximity Indexed Value (PIV) - Range of Value (ROV) - Grey relational analysis (GRA) - Measurement Alternatives and Ranking according to Compromise Solution (MARCOS) methods are used to rank the alternatives. The Copeland method is used to obtain a single rational ranking from different rankings. Based on the obtained results, it is concluded that energy companies in the Asian region are more sustainable than in the European region. Moreover, Thailand is the most sustainable country in the Asian region. The proposed framework can be contribute to the development of the energy sector.

Published: February 2023

The energy system is one of the foundations of a modern state, so, the need for its successful development and functioning is beyond doubt. In this regard, an objective assessment based on a set of indicators (viz. economic, energy and thermodynamic) is relevant. However, the traditional assessment of the operation of the energy system is carried out on the basis of such characteristics as the specific consumption of conventional fuel for electricity generation and heat release, which does not provide a comprehensive picture and is not always applied correctly. In this article, for the first time on the basis of the exergetic method, the calculation of the exergetic efficiency is considered. The use of this indicator makes it possible to obtain an objective assessment of the thermodynamic efficiency of such a complex formation as the energy system of a modern country in the easiest way. As an example, the unified energy system of Belarus in general and condensing power plants in particular have been analyzed for a fairly long period (2000–2021) and in various characteristic time periods. The method of calculating the exergetic efficiency is described. The results obtained are presented graphically. Attention is paid to the issue of the acceptability of the error when generalizing data on the initial flows of primary energy resources and product flows of centralized generating sources of the energy system. The contribution of condensing power plants to the total volume of electricity generation is analyzed, the most advanced of them are determined from a thermodynamic point of view. The calculation of their energy and exergetic indicators was carried out; the changes associated with the commissioning of the Belarusian NPP were considered. The conclusion is made that further reconstruction of energy sources of the power system in order to reduce the relative weight of natural gas in the incoming part of the energy balance to 50 % is expedient. This can be achieved by increasing the thermodynamic efficiency.

Introduction: Colombia has 50,912,429 inhabitants. Only 50–70% of the population could effectively access healthcare services. The Emergency Room (ER) is a main contributor to the in-hospital care system, since up to half of the admissions comes through. Telemedicine becomes a tool to facilitate effective access to healthcare services, improve the opportunity of care, reduce diagnostic variability, and reduce costs associated with health. The aim of this study is to describe the experience of a Distance Emergency Care Program through Telemedicine (TelEmergency), to improve specialist access for patients at the Emergency Room (ER) in low- and medium-level care hospitals in Colombia.Methods: Observational descriptive study of a cohort including 1,544 patients during the program’s first two years. Descriptive statistics were used to analyze the available data. The data is presented with summarized statistics of sociodemographic, clinical, and patient-care variables.Results: The study included a total of 1,544 patients, the majority were adults between 60 and 79 years of age (n = 491, 32%). More than half were men (n = 832, 54%), and 68% (n = 1,057) belonged to the contributory healthcare regime. The service was requested from 346 municipalities, 70% (n = 1,076) from intermediate and rural settings. The most common diagnoses were related to COVID-19 (n = 356, 22%), respiratory diseases (n = 217, 14%) and cardiovascular diseases (n = 162, 10%). We observed 47% (n = 721) of local admissions either under observation (n = 58, 4%) or hospitalization (n = 403, 26%), limiting the need for hospital transfers. Program operation data revealed that 50% (n = 799) of the requests were answered within two hours by the medical staff. The initial diagnosis was modified in 7% (n = 119) of the patients after being evaluated by specialists at the TelEmergency program.Conclusions: This study shows the operational data collected during the first two years after implementation of the TelEmergency program in Colombia, the first of its kind in the country. Its implementation offered specialized timely management of patients at the ER in low- and medium-level care hospitals, where there is no availability of specialized doctors.

Current guidelines prioritize the use of the Azvudine in coronavirus disease 2019 (COVID-19) patients. However, the clinical effectiveness of Azvudine in real-world studies was lacking, despite the clinical trials showed shorter time of nucleic acid negative conversion. To evaluate the clinical effectiveness following Azvudine treatment in hospitalized COVID-19 patients, we identified 1505 hospitalized COVID-19 patients during the study period, with a follow-up of up to 29 days. After exclusions and propensity score matching, we included 226 Azvudine recipients and 226 matched controls. The lower crude incidence rate of composite disease progression outcome (4.21 vs. 10.39 per 1000 person-days, P=0.041) and all-cause mortality (1.57 vs. 6.00 per 1000 person-days, P=0.027) were observed among Azvudine recipients compared with matched controls. The incidence rates of initiation of invasive mechanical ventilation were also statistically different between the groups according to the log-rank tests (P=0.020). Azvudine treatment was associated with significantly lower risks of composite disease progression outcome (hazard ratio [HR]: 0.43; 95% confidence interval [CI]: 0.18 to 0.99) and all-cause death (HR: 0.26; 95% CI: 0.07 to 0.94) compared with matched controls. Subgroup analyses indicated robustness of the point estimates of HRs (ranged from 0.14 to 0.84). Notably, male Azvudine recipients had a stronger effectiveness than female recipients with respect to both composite outcome and all-cause death. These findings suggest that Azvudine treatment showed substantial clinical benefits in hospitalized COVID-19 patients, and should be considered for use in this population of patients.

Authors: Liu Bin , wang yumei , Zhu Sheng , Theodorakis Panagiotis , Song Fei , Rachid Bennacer , Chen Kun
Published: February 2023

Owing to its high efficiency and specific refrigeration power, elastocaloric refrigeration is a promising technology that is potentially endowed with replacing the conventional steam compression refrigeration. Here, we report on experimental results of the elastocaloric refrigeration process of natural rubber, achieving a maximum temperature drop during unloading of the natural rubber of 41.30 K with a temperature difference of 68 K between hot and cold ends at an ambient temperature of 253.13 K. Moreover, we provide analytical temperature variation equations for cooling and heating natural convections as a function of the Fourier (Fo) and Biot (Bi) numbers, which are fitted to the experimental data and can be used to provide predictions for future elastocaloric refrigeration equipment. Thus, our study unravels the potential of natural rubber as a promising elastocaloric material and its key properties for refrigeration technology.
Prognostic analysis of cuproptosis-related ferroptosis genes in lung adenocarcinoma
Authors: Sun Hongna , Dai Shuang , Xu Junnan , Sun Tao
Published: February 2023

Purpose
Lung adenocarcinoma is the most popular histological type of lung cancer. The 5-year survival rate of lung adenocarcinoma is low. Curpotopsis is a new-found regulated cell death mechanism. Copper binding to lipoylated proteins directly leads to iron-sulfur cluster protein loss, proteotoxic stress, and finally cell death. Similarly, ferroptosis is still a research hotspot. Our goal is to predict the survival of lung adenocarcinoma employing the cuproptosis-related ferroptosis genes (CRFGs).
Methods
First, we conducted the correlation analysis of ferroptosis- and cuproptosis-related genes to identify the most valuable CRFGs. And we illuminated the prognostic value and expression of the four CRFGs. Then, we examined the relevance between CRFGs and the immune microenvironment by ssGSEA analysis and the CIBERSORT algorithm. Lung adenocarcinoma patients in the training set were divided into high- and low-risk groups according to the result of the Lasso-cox analysis. We established a new risk score predictive model according to the CRFGs risk score and critical clinical characteristics, containing N stage and radiation. Finally, we applied receiver operator characteristics (ROC) and calibration curves to verify the prediction ability of the model.
Results
We identified four CRFGs (PANX1, AURKA, EIF2S1, and ACSL3) and successfully created a risk score dividing patients into the low- and high-risk groups. The area under the curve (AUC) of this risk score model displayed good clinical application value in predicting the survival of lung adenocarcinoma. KEGG enrichment analysis indicated that the CRFGs were primarily enriched in autophagy, PI3K-Akt, mTOR, and ErbB signaling pathways. High-risk score groups were featured by much more infiltration, a high expression of immune checkpoints except TGFB1, and shorter overall survival time, while low-risk score groups were featured by immunosuppression. In addition, this study further proved that CRFGs score might predict prognosis, drug treatment response to chemotherapy, target therapy, and immunotherapy among lung adenocarcinoma cancer patients.
Conclusion
These results of CRFGs provide new insight into lung adenocarcinoma and might encourage new methods for predicting the survival of lung adenocarcinoma and treating these patients.
Green or blue bodies to mitigate the urban heat island? The case of a compact European city

Published: February 2023

An understanding of the complex contributions of several factors to an urban heat island is crucial for the assessment of the impacts of planning on the thermal conditions within cities. This paper investigates the effects of various factors on the land surface temperature (LST) in three zones of Prague, the capital of the Czech Republic. The investigated factors include the normalized diﬀerence vegetation index (NDVI), proximity to lakes larger than 1000 m2 (Lakes), proximity to the river (River), building coverage (BC), and building height (BH). Their interrelationships are explored in a square grid of 30 × 30 m using Landsat-8 data on LST measurements and multiple regression models. The results imply that NDVI significantly reduces LST, followed by the River if within 200 m of it, while the effect of Lakes is negligible. The effect of BH is generally low, though it often also reduces the LST in the outer compact city. BC is a predominant factor in the city, generating a warming effect, which increases with the city’s compactness. The main planning implications are to base urban heat island mitigation strategies on compensating for building coverage with live and dense green bodies in the compact city, promoting vertical development.

Current care in multiple sclerosis (MS) primarily relies on infrequently obtained data such as magnetic resonance imaging (MRI), clinical laboratory tests or clinical history, resulting in subtle changes that may occur between visits being missed. Mobile technology enables continual collection of data and can pave the path for predicting complex aspects of MS such as symptoms and disease courses. To this end, we conducted a first-of-its-kind observational study called MS Mosaic. First, we developed and publicly launched a mobile app for collecting longitudinal data from MS subjects in the United States. Second, we ran the study across 3 years in order to capture complex patterns for this slow progressing disease. Finally, we retrospectively developed three classical ML methods and two deep learning models to accurately and continually predict the incidence of five high-severity symptoms (fatigue, sensory disturbance, walking instability, depression or anxiety and cramps) three months in advance.

Many attempts for developing the BiVO4 photocatalysts by coupling with other metal oxide semiconductors with appropriate band potentials have been performed by many researchers to improve the separation of photogenerated electron-hole pairs and increase the charge carrier lifetimes. In the present work, the OH radical formation of the nanocomposite photocatalysts of visible light responsive BiVO4 with other semiconductor photocatalysts such as particulate TiO2, SnO2, and ZnO was investigated. The OH radical formation by the photocatalytic reduction reaction of H2O2 on the TiO2 surface has already been proposed by several researchers. Here, the possible roles of OH radical formation by the reduction reaction of H2O2 on the photocatalytic surfaces of the BiVO4 – X (X =TiO2, SnO2, and ZnO) nanocomposite photocatalysts were also examined by investigating the effects of H2O2 on the amount of the OH radicals formed by the photocatalytic reactions. Finally, experiments of degassing oxygen in the visible light irradiated BiVO4 -TiO2, BiVO4 -SnO2, and UV-irradiated BiVO4 -ZnO nanocomposite photocatalysts were performed to investigate the relative roles of reaction channels of OH radical formation of (a) the direct reduction of H2O2 and (b) indirect reduction reaction of H2O2 via superoxide radical anion (･O2-). It was found that there were differences in the relative roles of OH radical formation by the reaction channels of (a) and (b) for the visible light irradiated BiVO4 and in the visible light irradiated BiVO4 -TiO2, BiVO4 -SnO2, and UV-irradiated BiVO4 -ZnO nanocomposite photocatalysts.

Published: February 2023

This article investigates the dynamical effect of the dissipation forces, namely the Poynting-Robertson (PR) drag and nebular gas (Stokes) drag on the photogravitational magnetic-binary problem (PMBP) where the smaller primary is an oblate body and the bigger primary is the source of radiation. We have settled the equations of motion. The parametric evolution of the position and existence of equilibrium points and their linear stability are presented. Further, Newton-Raphson (N-R) basins of attraction have been plotted with the effect of Poynting-Robertson (PR) drag and nebular gas (Stokes) drag by Mathematica Software. Numerical results indicate that the ratio of magnetic moment λ has a significant impact on the location, stability of the equilibrium points, and the Newton-Raphson (N-R) basins of attraction of the problem. It is observed that there exist either nine or eleven equilibrium points for different values of mass parameter µ and the ratio of magnetic moment λ. Further, we observed that all equilibrium points are unstable in the Lyapunov sense. It is identified that in every case, the basins of convergence corresponding to the collinear equilibrium points L1 and L3 have infinite extents. Our numerical study suggests that the progression of the attracting domains in this dynamical system is very complicated. It is found that spacecraft is drifted from equilibrium points as a function of time due to instability of equilibrium points and drift is most for L7 point.
Aktives Integrieren von Repräsentationen bei interaktiven Augmented Reality-Anwendungen

Augmented Reality (AR) bietet viele Möglichkeiten, mit Lernmaterialien zu interagieren. Dabei ist es wichtig, dass diese zielgerichtet eingesetzt werden, um Lernende nicht zu überlasten, jedoch relevante Verarbeitungsprozesse anzuregen. Unterschiedliche Repräsentationsformen selbst extern zuzuordnen (Aktives Integrieren) kann relevante Organisations- und Integrationsprozesse anregen und wird hier auf eine AR-Lernanwendung übertragen, die virtuelle und reale Komponenten verknüpft. In einem experimentellen Vergleich zu einer vorintegrierten Version (N = 94), werden Variablen zur kognitiven Belastung, Aufgabenbelastung und dem Lernerfolg erfasst. Die Hypothesen, dass das Aktive Integrieren zu höherem Germane Cognitive Load und besserem Lernerfolg führt, wurden nicht bestätigt und die deskriptiven Daten zeigten sogar einen gegenteiligen Unterschied. Auch die meisten weiteren Hypothesen mussten verworfen werden, da sich keine signifikanten Unterschiede zeigten. Nur die wahrgenommene Leistung war mit Aktivem Integrieren signifikant höher. In der explorativen Betrachtung von Bildschirmaufnahmen in der Lernphase zeigte sich, dass beim Aktiven Integrieren die virtuellen Elemente in der AR-Anwendung weniger stabil und insgesamt weniger häufig sichtbar waren. Die Ergebnisse werden hinsichtlich dieser Besonderheit und der hohen Komplexität bei der AR-Nutzung diskutiert, weitere Forschung und der Einsatz interaktiver AR in der Praxis werden empfohlen.
Und was kommt nach der Zeitreise?

Published: February 2023

Viele Virtual Reality-Anwendungen (VR), die sich historischen Themen widmen, eint ein Ziel: Zeitreisen wirklich werden lassen. Über die Technologie soll es den Rezipierenden möglich gemacht werden, in Simulationen vergangener Zeiten und Orte einzutauchen und diese zu erleben. Aber was passiert nach diesem «Zeitreiseerlebnis»? Da auf das vermeintliche «Eintauchen» in die Vergangenheit ein «Auftauchen» in der Gegenwart folgt, wird in diesem Beitrag die Frage untersucht, wie das «Auftauchen» aus einer virtuellen Umgebung didaktisch begleitet werden kann. Basierend auf medienpsychologischer und geschichtsdidaktischer Forschung wurden Materialien für die Begleitung des «Auftauchens» aus der VR entwickelt und in einer Laborstudie (N = 70) eingesetzt. Genutzt wurde ein 2x2 Between-Subjects-Design, in dessen Rahmen die Auswirkungen der Materialien und des emotionalen Inhalts der VR auf Präsenzerleben, Emotionen und Geschichtsbewusstsein qualitativ untersucht wurden. Die Ergebnisse zeigen, dass die didaktische Begleitung des «Auftauchens» durch die Rezeption weniger emotionalisierender Inhalte und Materialien positive Effekte auf die Äusserungen von Geschichtsbewusstsein hat.
