Croatian Tourism Sector and Crisis Management
Authors: Mikac Robert , Kravarščan Karla
Published: November 2021

Tourism
is an extremely important economic sector for the Republic of Croatia and an
important component of certain economic and social activities, such as
transport and business of travel agencies, trade, catering, agriculture, and
numerous service activities. Many Croatian citizens are directly, indirectly, or
partially employed in the said sectors. Many depend on it – from individuals,
through various business entities and tourist destinations, to the state itself
which generates almost 20 percent of the annual state budget revenue from
tourism. Given the multilevel and multifunctional importance of tourism, it is
important to research how it is organized for emergencies that can cause
significant disruptions in the operation and revenue generation. The goal of
this paper is to analyze how and how successfully the tourism sector coped with the COVID-19 pandemic and the resulting crisis, what crisis
management mechanisms were developed and how they were used during 2020.

This article talks about a lot of systems to transform customers into resources proposed for organizations while making faithful customers. The technique that is the focal point in this article is customer Relationship Management (CRM). This is on the grounds that without a CRM system, organizations neglect to reap the advantages of CRM. CRM is fundamentally significant for the organization's future. CRM innovation empowers organizations to all the more likely comprehend customer conduct, foresee their conduct later on, give altered customer encounters, and assemble long haul customer connections. Nonetheless, given that CRM is just restricted by innovation it will be a serious mix-up for the organization. Organizations can't give excellent customer worth, administration and experience just by putting resources into CRM innovation. This article depicts customer life cycle the executives and proposes an all encompassing system for customer life cycle the board. This section finishes by examining methodologies for transforming customers into resources and making satisfied customers.

Learning is said to be good if during the learning process all students are active or participate in answering or asking questions. The learning process is a form of educative interaction, which is an educationally valuable interaction that consciously sets the goal to change a person's behavior and actions. Educational interaction must describe a two-way active relationship between teachers and students with a number of knowledge as the medium. In educative interactions, the elements of teachers and students must be active, it is impossible for an educational interaction process to occur if only one element is active. Active in the sense of attitude, mental, and deed.

Authors: Choi Hoon Sung , Kim Jin Taek , Lee Hong Kyu , Park Wook Ha , Kim Pak Youngmi , Lee Sung Woo
Published: November 2021

Background: Mitochondrial dysfunction is strongly associated with several kidney diseases. However, no studies have evaluated the potential renal hazards of serum mitochondria-inhibiting substance (MIS) and aryl hydrocarbon receptor ligand (AhRL) levels.Methods: We used serum level of MIS and AhRL and clinical renal outcomes from 1,511 participants of a prospective community-based cohort in Ansung. MIS was evaluated based on intracellular adenosine triphosphate (MIS-ATP) or reactive oxygen species (MIS-ROS) generation measured using cell-based assays.Results: During a mean 6.9-year follow-up, 84 participants (5.6%) developed a rapid decline in kidney function. In the lowest quartile group of MIS-ATP, patients were older and had metabolically deleterious parameters. In multivariate logistic regression analysis, higher MIS-ATP was associated with decreased odds for rapid decline: the odds ratio (OR) of 1% increase was 0.977 (95% confidence interval [CI], 0.957 to 0.998; P=0.031), while higher MIS-ROS was marginally associated with increased odds for rapid decline (OR, 1.014; 95% CI, 0.999 to 1.028; P=0.055). However, serum AhRL was not associated with the rapid decline in kidney function. In subgroup analysis, the renal hazard of MIS was particularly evident in people with hypertension and low baseline kidney function.Conclusion: Serum MIS was independently associated with a rapid decline in kidney function, while serum AhRL was not. The clinical implication of renal hazard on serum MIS requires further evaluation in future studies.

Goal. Consider the management of patients with effort thrombosis (Paget-Schretter syndrome).The article presents the modern vision of the problem of effort thrombosis. This review is aimed at describing the epidemiology, pathophysiology, diagnosis and treatment of patients with Paget-Schretter syndrome. SPS occurs spontaneously, as a rule, in young, healthy and active patients aged 20-30 years after strenuous physical activity. The ratio of men and women is 2:1, recently there has been a growing trend among women. The main complaints of patients with SPS include swelling of the affected limb, discomfort when moving the affected arm, pain and heaviness when trying to raise the arm up. When examining these patients, attention is paid to hyperemia of the skin or their cyanotic nature, pasty limbs, as well as an enhanced venous pattern on the shoulder, the so-called Arshel sign. The diagnosis is based on the data of anamnesis, physical examination, the “gold standard of diagnostics” – ultrasound examination of veins, the sensitivity and specificity of which is 70-100%. The first step in the diagnosis can be the evaluation of the D-dimer, with its negative values, the SPSH is rejected. With an obvious clinic and controversial results of serial ultrasound examinations, other imaging methods are used, such as computed contrast tomography, magnetic resonance imaging, the diagnostic value of which is especially significant in occlusive venous thrombosis.SPS differs not only from DVT of the lower extremities, but also from secondary DVT of the upper extremities, which determines the peculiarities of management of this category of patients, including surgical treatment aimed at preventing subclavian vein compression in the future. The article summarizes the experience in the management of patients with blood thrombosis.

Our observation demonstrates a case of a 40-year-old female with idiopathic pulmonary arterial hypertension World Health Organization functional class III, who was admitted to NMRC of Cardiology repeatedly due to disease progression including dyspnea worsening and exercise tolerance decrease after previous COVID-19 infection on riociguat (7.5 mg daily), macitentan (10 mg daily) and selexipag (1600 mcg daily) therapy. Clinical examination demonstrated high-risk status according to the expected 1-year mortality. Due to unreleased treatment goals and high-risk status, we performed transition from selexipag to inhale iloprost. After therapy escalation the patient demonstrated a significant improvement in clinical condition, dyspnea reduction and exercise tolerance increase. The current treatment strategy for pulmonary arterial hypertension is based on regular multiparametric risk stratification approach in PAH patients. The impact of COVID-19 may become an important cause of clinical worsening in PAH patients during COVID-19 pandemic. Directed on vasodilatation and antiproliferation mechanisms of action of PAH-specific drugs are supposed to be protective in COVID-19 patients. However, the probability of clinical worsening in PAH patients despite PAH-specific therapy intake needs to be closely monitored to perform timely treatment correction in order to achieve low-risk status and to improve the prognosis of PAH patients.
Conversion Experience of Akan Christian Royals in Ghana
Authors: Opuni-Frimpong Kwabena , Ntiamoah Michael Kwadwo
Published: November 2021

The study is an examination of the conversion challenges confronting Akan Christian Royals in Ghana. The Western missionaries and missionary established churches demand that as part of their conversion requirements, Akan Royals must reject and disassociate themselves from the Black Stool, ancestors and all ancestral related activities. The Royals who claim that their families have become Christian royal families insist that authority symbols like the Black Stools and ancestral ceremonies like the Adae do not take the place of the sovereignty of God and the Lordship of Christ in their belief system. Moreover, participation in Palace services prepares them for traditional leadership and does not take them away from their faith in Christ. The traditional leadership institutions and the Royals that welcomed the Western missionaries, provided them with hospitality, security and resources for the missionary work have come to be considered as unchristian and an anathema to the Christian faith. The position of the church has created tensions within Akan Christian Royal and put the genuineness of their conversion in doubt. The study which is qualitative in nature uses both primary and secondary methods in its information gathering. Its findings provide responses to some contemporary tensions in gospel and culture studies in African Christianity.

«IMPORTANCE OF THE PNEUMOCOCCUS IN COMMUNITY-ACQUIRED PNEUMONIA IN TENDER-AGE INFANTS ON THE BACKGROUND OF VACCINATION»
The authors of the manuscript provide data demonstrating that una pneumonia against the background of vaccination is accompanied by a change in the etiological structure. The article is a new idea and overall it is well written and structured.
However, simple study design, lack of patient baseline and follow-up data limit the conclusion of withdrawal.
I invite the authors to solve the following questions:
1) There are many spelling, grammatical and punctuation errors. Authors should correct mistakes and rewrite the article in a clear and understandable style. I have visited the authors with the help of a language expert on rewriting.
2) The main problem of the manuscript is poor statistical processing and statistical reporting. The authors stated: “All data were expressed as confidence intervals. Thus, it is unclear whether the etiological structure was normally distributed. Moreover, following normal scientific practice, authors should indicate specific statistical significance values ​​when comparing each test parameter.
3) The cited literature is relevant to the research and meets the requirements of the journal. But mentions of 9/19 were published over 10 years ago. I recommend reading current research on this topic.
In conclusion, the work makes a good impression. On the other hand, it can be published after significant changes with reference to the comments mentioned above, including bug fixes and rewriting of the article in a clear and easily understandable style.

Authors: Ghanam Walaa , Bebars Shaimaa M. M.
Published: November 2021

BACKGROUND: Cluster of differentiation 274 (CD274) antigen has been investigated in tumors to evaluate its regulation and effect as a predictive of targeted therapy. Its expression and effect in lymphoma have raised interest recently. However, results were mixed and showed wide variations.

AIM: This study aims to explore and compare CD274 antigen immunohistochemical expression in tumor and peri-tumor cells of classic Hodgkin lymphoma (HL) and diffuse large B cells non-HL (NHL) and its relation with clinicopathological criteria.

METHODS: This work was carried out on 78 cases of lymph node excision biopsy (48 HL and 30 NHL). Prepared sections were applied for immunohistochemistry using CD274 monoclonal rabbit anti-human (programmed cell death protein 1 [PD-L1] ZR3-ASR, a Sigma Aldrich company). Assessment of CD274 antigen in tumor cells was considered positive if detected in >10% (membranous staining with cytoplasmic accentuation). Peri-tumor cells were scored as: 0, no positive cells/high-power field (HPF); 1, <10 positive cells/HPF; 2, 10–30 positive cells/HPF; 3, >30 positive cells/HPF.

RESULTS: CD274 antigen was expressed in 53.8% of total lymphoma cases with significantly more expression of CD274 antigen in HL than NHL (66.7% vs. 33.3%). Classic HL showed significantly higher expression of CD274 antigen in tumor and peri-tumor cells and significant association with elevated erythrocyte sedimentation rate and lactate dehydrogenase and male gender.

INTERPRETATION AND CONCLUSION: There is a more frequent and significant expression of CD274 antigen in classic HL than NHL cases in tumor and peri-tumor cells and a significant association with bad prognostic criteria in classic HL. High expression of CD274 antigen in classic HL proposes its potential use as a marker, especially for prognostic indication.

Authors: Gondo Harry Kurniawan
Published: November 2021

BACKGROUND: Preeclampsia is a major obstetric problem worldwide, especially in developing countries that can cause maternal and fetal morbidity and mortality that affect 2–10% of pregnancies worldwide. More than 4 million pregnant women each year develop preeclampsia and cause 15–20% of maternal deaths worldwide. There are several high-risk factors associated with preeclampsia. Diabetes mellitus is one of the risk factors for preeclampsia. Preeclampsia has been shown to have higher levels of Th1 (pro-inflammatory) products and lower levels of Th2 (anti-inflammatory) products compared to normal pregnancy in blood serum. Interleukin (IL) 1, IL-2, IL-8, tumor necrosis factor (TNF)-alpha, and interferon gamma are Th1 cytokines or pro-inflammatory cytokines that can induce inflammatory reactions and are associated with pregnancy complications such as repeated abortion, preterm labor, rupture of membranes. preeclampsia, and stunted fetal growth. In contrast, Th2 cytokines such as transforming growth factor-β (TGF-β), IL-4, IL-5, IL6, and IL-10 are associated with normal pregnancy.

AIM: This study aims to prove the effect of giving Moringa leaf powder (M. oleifera) to decrease blood levels, , so this study will answer the effect of Moringa oleifera leaf powder on blood level of IL-6, IL-10, TNF-α and TGF-β

METHODS: A total of 30 rats were checked for sugar levels on day 4 after being induced by alloxan for 18 days to see if the rats were already in a hyperglycemic state. Then, they were divided into six groups, each group contained five pregnant white rats. Group 1 was the negative group (without being given alloxan), Group 2 was positive (given alloxan 150 mg/day/kg BW), and Groups 3, 4, 5, and 6 were given alloxan 150 mg/day/kg BW and each given a dose of 100 Moringa leaf powder; 200, 400, and 800 mg/day/kg body weight. After alloxan was induced and given a dose of Moringa leaf powder according to each group, blood samples were taken to separate the serum and continued with the ELISA method to calculate the levels of IL-6, IL-10, TNF-α, and TGF-β.

RESULTS: The administration of Moringa leaf powder at a dose of 800 mg/day/kg BW was able to increase the levels of IL-10 in the positive control Group 4 by 7.211 mIU/ml and reduced levels of IL-6 in the 8th dose group by giving Moringa leaf powder as much as 800 mg/day/kg body weight by 2.112 mIU/ml, was able to increase TGF-β levels in the dose Group 4 by giving Moringa leaf powder as much as 800 mg/day/kg BW, amounted to 1049.066 mIU/ml, and decreased TNF-α levels in the dose Group 4 by giving Moringa leaf powder as much as 800 mg/day/kg BW mIU/ml.

In this paper, we have established some new Hermite–Hadamard–Mercer type of inequalities by using $ {\kappa} $–Riemann–Liouville fractional integrals. Moreover, we have derived two new integral identities as auxiliary results. From the applied identities as auxiliary results, we have obtained some new variants of Hermite–Hadamard–Mercer type via $ {\kappa} $–Riemann–Liouville fractional integrals. Several special cases are deduced in detail and some know results are recaptured as well. In order to illustrate the efficiency of our main results, some applications regarding special means of positive real numbers and error estimations for the trapezoidal quadrature formula are provided as well.

Published: November 2021

As of August 2021, COVID-19 is still spreading in Japan. Vaccination, one of the key measures to bring COVID-19 under control, began in February 2021. Previous studies have reported that COVID-19 vaccination reduces the number of infections and mortality rates. However, simulations of spreading infection have suggested that vaccination in Japan is insufficient. Therefore, we developed a susceptible–infected–recovered–vaccination1–vaccination2–death model to verify the effect of the first and second vaccination doses on reducing the number of infected individuals in Japan; this includes an infection simulation. The results confirm that appropriate vaccination measures will sufficiently reduce the number of infected individuals and reduce the mortality rate.
Microlearning and computer-supported collaborative learning: An agenda towards a comprehensive online learning system
Authors: Garshasbi Soheila , Yecies Brian , Shen Jun
Published: November 2021

With the rise of the COVID-19 pandemic and its inevitable consequences in education, increased demand for robust online learning frameworks has occurred at all levels of the education system. Given the transformative power of Artificial Intelligence (AI) and machine learning algorithms, there have been determined attempts through the design and application of intelligent tools to overcome existing challenges in online learning platforms. Accordingly, educational providers and researchers are investigating and developing intelligent online learning environments which share greater commonalities with real-world classroom conditions in order to better meet learners' needs. However, short attention spans and the widespread use of smart devices and social media bring about new e-learning systems known as microlearning (ML). While there has been ample research investigating ML and developing micro-content, pedagogical challenges and a general lack of alternative frameworks, theories and practices still exist. The present models have little to say about the connections between social interaction, including learner–content, learner–instructor and learner–learner communication. This has prompted us to investigate the complementary aspects of Computer-supported Collaborative Learning (CSCL) as an interactive learning model, along with an embedded ML module in the design and development of a comprehensive learning platform. The purpose of this study is to explore the pedagogical frameworks and challenges with reference to interaction and retention in online learning environments, as well as the theoretical and pedagogical foundations of ML and its applications. In addition, we delve into the theories and principles behind CSCL, the main elements in CSCL, identifying the issues and challenges to be faced in improving the efficacy of collaboration processes and outcomes. In short, we aim to synthesize how microlearning and CSCL can be applied as effective modules within a comprehensive online learning platform, thereby offering STEM educators a relevant roadmap towards progress that has yet to be offered in previous studies.
Non-routine mathematical problem-solving: Creativity, engagement, and intuition of STEM tertiary students

Published: November 2021

This study set out to evaluate an intervention that introduced a period of non-routine problem-solving into tertiary STEM lectures at four tertiary institutions in New Zealand for 683 students. The aim was twofold: to attempt to increase student engagement and to introduce them to the kind of domain-free abstract reasoning that involves critical, creative, and innovative thinking. This study was conducted using a mixed-methods approach, utilizing different types of instruments to gather data: comprehensive student pre- and post-test questionnaires, a content validation survey for the questionnaires, focus group interviews (student participants), open-ended questionnaire (lecturer participants), and naturalistic class observations. The main findings are as follows. Students' behavioural engagement was significantly greater during the intervention. Perceptions of the utility value of the activity improved at the end of the semester for all students. There were no significant changes in students' convergent thinking (problem-solving), intuition, or creativity (originality, fluency, and elaboration traits of the divergent thinking) during the course, probably due to the relatively short timescale of the intervention. However, overall, the results of the investigation suggest that with a relatively small effort, teachers can improve STEM student engagement by devoting a few minutes per lecture on non-routine problem-solving. This is something that can be easily implemented, even by those who primarily teach in a traditional lecturing style.

Una vez transferida la información es retribuida por medio de la computadora de Adafruit-IO y traducida como base de datos o gráficas lineales. AIOR es de bajo costo y pertenece a los sensores de datos del Internet of Things-(IoT). Los usuarios son guiados visualmente a los sensores correspondientes en Revit. El algoritmo de detección de fallas se basa en los niveles de comodidad establecidos por el ASHRAE-55-2017. El algoritmo localiza los sensores con valores anormales y los marca con diferentes colores en imágenes tridimensionales. El contribuidor clave para es el sensor de datos es visible dentro de un programa de BIM. La información puede ser comparada con los datos establecidos por el ASHRAE-55 y el sistema de alerta es visualizado en Revit cuando estos valores están fuera de los estándares establecidos.

La presente investigación forma parte de una tesis doctoral destinada a caracterizar diferentes sistemas sismorresistentes utilizados en la arquitectura histórica de fábrica. El objetivo es analizar y clasificar en tipos estructurales y constructivos estos sistemas, en gran medida, todavía desconocidos. Contribuir a disipar esta laguna del conocimiento representa un importante avance, no solo para continuar completando la historia del patrimonio histórico construido, sino también en cuanto se refiere a la posibilidad de realizar una racional conservación de este importante legado. La metodología analítica seguida es la misma que se utilizó, hace 17 años, en el caso de la catedrales góticas españolas, que sirven de referencia a la investigación en curso. El artículo pone de manifiesto las diferencias y analogías existentes entre los sistemas sismorresistentes detectados en las construcciones de fábrica histórica sismorresistentes analizadas en España e Irán.
Branding Chinatown and the opposition between national and local politics in the United Kingdom
Authors: Dang Quôc-Dung
Published: November 2021

Despite the rolling back of multiculturalism at government level, the realities of a diverse society remain very much visible at the local level. In the current context of globalisation and cosmopolitanism and as part of a broader effort to globalise London, the English capital still resorts to de facto multiculturalist policies to enhance its diversity in terms of ethnic groups. London’s Chinatown is one representative example of this phenomenon. The neighbourhood presents an important economic opportunity resulting from its cultural landscape. Thus, both public authorities and the corporate world seek to profit from the area’s cultural wealth, hence their attempts to negotiate Chinatown as a product by engaging a narrative that fits Western imagination. London’s Chinatown has thus been marketed and packaged for consumption through different branding strategies that focus on its cultural representation. The study of this ethnic enclave adds to the existing empirical and normative literature of multiculturalism by exploring the contrast in local and national politics in terms of integration and multicultural policies in the United Kingdom, thus participating in the debate on “Living together in the UK”.

The activities that depend on direct interaction with the customers were the most affected by COVID-19's restrictions. These include the activities developed by salespeople. This study aims to analyse the impact of salesmanship skills on sales strategy implementation and salesperson performance during the COVID-19 crisis. To achieve the research objective, the authors collected a set of data through a survey (n=517) to test a proposed conceptual model based on the literature. The findings of the study demonstrate that the salesmanship skills are an important resource in highly disruptive environments and impacts sales strategy implementation and salesperson performance. In addition, the study also reveals the important role of digital skills and intrinsic motivation during COVID-19 times. The results attained can be used as a guide to design an effective strategy for sales activities in adverse times.
A Methodological Approach to Analyzing Digital Game-Based FL Use and Learning
Authors: Ibrahim Karim Hesham Shaker
Published: November 2021

The potential of digital gaming to facilitate foreign language (FL) learning has been established in many empirical investigations; however, the pedagogical implications of these investigations remain rather limited. A potential reason for this limitation is that the FL learning potential of digital games is embedded in the gaming ecology and shaped by different forces in that ecology. However, to date most empirical studies in the field have focused primarily on the linguistic behavior of gamers rather than the gaming ecology. A potential reason for this is the lack of a robust methodological approach to examining game-based language use as an ecological, multidimensional activity. To address this research gap, this chapter proposes the diamond reconstruction model, a dynamic, multidimensional, and ecology-sensitive approach to de- and re-constructing game-based FL use. Grounded in theories of gameplay, and informed by a conceptual model of game-based FL use, the model reconstructs gameplay episodes by gathering detail-rich data on social, cognitive, and virtual dimensions.

The digital games market is around 109 billion dollars. In this scenario, games as tools for mental and educational stimulation have been highlighted. They allow the connection between friends, the narrowing of family ties, artistic expression, improvement of aspects related to health, institute mechanisms for business and advertising, as well as constitute opportunities for differentiated training and simulations. Such artifacts are also mediators for building knowledge, as well as developing or exercising skills and attitudes, since they involve the flow state. For this it is necessary to make use of adaptability that in the educational scope allows the personalization of the experience to extend the immersion and fun. The present chapter presents a review to subsidize the expansion of the mapping of games' uses developed by Klopfer, Osterweil, and Salen, as well as to establish their relation with the deliberate practice to institute immersive and meaningful educational proposals.

Video games are widely and increasingly adopted in the educational field thanks to their inherent engaging, immersive, and adaptive capacities. Yet, one of the greatest problematic in educational games design remains how to create ludic and adaptive experiences without going astray from the targeted learning objectives. In creating adaptive educational games, modeling the learner/player is a prerequisite. This chapter highlights the importance of educational standards in learning content design and proposes an adaptive mechanism “AMEG” based on IMS learning design and artificial intelligence that model learners using game metrics and adapt the gameplay as well as the learning content. As a practical experimentation of the mechanism, MathQuests, an educational game that helps in teaching mathematical operations for first year middle school students was created.

This study aims to investigate the factors that enable or hinder the implementation of game development activity in the instructional process. One instructor and 15 gifted students between the ages of 11 and 15 took part in the study. The students developed computer games related to science topics using MS Kodu game engine within the implementation process. According to the findings, it is seen that instructional practices have great importance, and the instructor plays a key role in the activity. Making and playing games have been the greatest motivation resource for students. In addition, the social environment can be an important tool in sustaining students' motivation levels. The students' negative attitudes toward educational game topics and non-computer activities hinder the successful implementation of the activity. The MS Kodu game engine might be appropriate for novice designers but not be enough for teaching programming concepts. Team-based game development activity is believed to be useful for developing advanced games and increasing the level of interaction between students.
