Authors: Mora Forero Jorge Alexander , Nieto Mejía Alvelayis
Published: May 2023

This research allows to know the symbolic value and the representations that tourists give to the traditional utilitarian and artistic handicraft work in pottery and ceramics, to identify the criteria of inclusion and exclusion at the time of purchase in Ráquira Boyacá, considered as the handicraft capital of Colombia. The objective of this research is to identify the potential of creative tourism based on utilitarian and artistic crafts as a strategy for economic revitalization and cultural dissemination in the municipality of Ráquira Boyacá. In addition, it is based on the main categories which identifies having a support or information on a participatory scenario involving artisans, tourists, merchants and the community. Likewise, the type of research handled in this project is qualitative where the analysis is interpretative and reflexive. In this way, ethnographic interviews are carried out to obtain decisive information from the artisans in relation to the techniques, know-how and traditional knowledge associated with their artisan work in which tourism contributes to the dissemination, valuation and conservation of artisan work, privileging the principles of sustainability, quality and responsibility of cultural and creative tourism. Therefore, as a result, relevant information from tourists who visit Ráquira was evidenced, with the purpose of knowing the symbolic value and the representations they give to artisan work. Equally important, concluding this research, there is a great potential to strengthen creative tourism products based on handicrafts in Ráquira.

The comparative study focuses on the resilience of small tourism enterprises in coastal and marine tourism in three Baltic Sea countries - Estonia, Finland and Latvia. The research aim is to explore the response of the micro and small-scale tourism enterprises in Estonia, Finland and Latvia to COVID-19 and their development plans in the context of the pandemic. These countries share common strengths and weaknesses in tourism as well as their main tourism resources (e.g., the significance of natural resources), partially overlapping target markets. Data were collected in coastal regions in all three countries by using semi-structured interviews (Estonia N=12, Latvia N=12, Finland N= 5). Additionally, a quantitative data collection tool - a survey (N=51) was used in Finland. The content analysis generated several themes: (1) The ability of an enterprise to adapt to changes; (2) future expectations; (3) educational needs; (4) mind-set changes of entrepreneurs as a result of corona-pandemic and motivation to learn. Results suggest that more than before, coastal entrepreneurs estimate the rationality of decisions and the feasibility of investments. They report the ability to transform the design of tourism services to move towards touchless, digitized solutions as well as present an ability to produce unique service ideas under the pressure of the pandemic. Future expectations are related to the need for intensified cooperation among public and private sectors and different sectors of the economy to ensure entrepreneurial resilience and/or development. Entrepreneurs also stress their expectations regarding public (e.g. in nature areas) infrastructure development.  COVID-19 pandemic has contributed to the emergence of business shrinkage strategies and vigilance toward development. The pandemic aggravated the deficit of employees and is directly linked to human resource motivation programs and the lack of resources needed to maintain that. Educational needs reveal several categories of topics entrepreneurs would like to learn about such as marketing, tourism product, and service design, management, and cooperation. The results in the three countries show a lot of similarities, the biggest differences can be seen in the various educational needs, also not in all countries the pandemic increased awareness of the role of cooperation or need to improve the quality of service when facing falling demand.
The Influence of the Heath Literacy on Tourist Health and Wellbeing Choices
Authors: Coelho José Rafael , Costa Teresa , Nunes Sandra
Published: May 2023

Currently, there is a growing tendency for tourists to look for new experiences during their leisure or vacation trips. Increasingly, these experiences are echoed in pleasant places of relaxation. However, a classic tourist activity continues to be in high demand – hydrotherapy – which no longer offers only the usual and traditional treatments with water, but also other alternatives, bringing together a complex of proposals for all tastes and all budgets. Travel, stay, gastronomy, enjoy the landscapes and historical and cultural sites are today added to places where health and well-being complement tourists who seek it in a very rewarding way. However, choosing where to sleep, what to eat and what to visit is different from deciding which health and wellness treatments you can and should get and which ones will be beneficial and not harmful to your needs. The research question is, therefore, to understand if the health and wellness tourist influences his choices of health and wellbeing. By carrying out an empirical study, based on a questionnaire survey, some answers were obtained to the questions raised by the work and the conclusion shows that some results in terms of Health Literacy, differ slightly from previous studies.
Co-creating Experiences in Cultural Events: The Case of Three Portuguese Festivals
Authors: Teixeira Costa Paulo , Carvalho Rui , Veríssimo Medéia , Costa Carlos
Published: May 2023

Experience co-creation has received much attention in tourism, events, and festivals literature. Often shared and consumed collectively, those experiences positively affect visitors’ satisfaction, the volume of expenditure, and levels of happiness, being essential for businesses, attractions, and destinations. As add-ons, co-creation experiences can play a significant role in diversifying and differentiating the supply of cultural events while contributing to fostering events and festivals as tools of territorial development. Within this context, this exploratory research aims to analyse the characteristics of co-creation experiences developed in three cultural events. Considering participation and personalisation as two relevant dimensions of experience co-creation, this paper analyses how they can be applied in the context of cultural events. The study follows a comparative approach, describing three cases of cultural events on the central coast of Portugal (Aveiro region). The methodology was based on participant observation and documental analysis of secondary data, namely the events and festivals characteristics, cultural programs, websites, and promotional materials. Major results indicate that two of the three events analysed have better conditions for the participation of visitors and the local communities, mainly due to the considerable number of activities that provide active participation and learning. On the other hand, one of the festivals fosters better conditions for the personalisation of services and experiences compared to the others, mainly due to the venue's characteristics and the way the program is designed. In that sense, the paper highlights the potential for the inclusion of co-creation experiences in events and festivals, providing a set of good practices for events and festival organisers and other tourism agents such as tourism businesses, tourism professionals, and local communities.
Perceptions and Attitudes of Domestic Tourists toward Ecotourism
Authors: Balida Don Anton
Published: May 2023

Although authorities are aware of the economic benefits of ecotourism, domestic tourism in Oman often fails to prioritise environmentally conscious visits to natural areas that incorporate observation and education. Without greater awareness, the preservation of these destinations will remain a mere aspiration. This study aimed to collect data on the perceptions and attitudes of local tourists towards ecotourism in Oman, focusing on three popular nature destinations from different governorates. To address the research problem, a mixed approach, along with the descriptive correlational design, was used. Over a month-long survey, primary data was collected from fifty respondents, revealing an overwhelmingly positive attitude towards ecotourism in Oman. The potential for ecotourism in the country was rated as ‘High,' reflecting optimism about the future of the tourism sector. However, respondents also acknowledged that ecotourism can have a ‘High’ detrimental impact on the ecosystem. Economic and sociocultural implications were considered to be of ‘Very High’ importance. The positive perceptions and attitudes towards ecotourism in Oman were mainly driven by the economic and sociocultural benefits it offers. The results of this study indicate a promising outlook for ecotourism in Oman, as long as sustainable regulations are in place. Planning is crucial for every aspect of ecotourism, particularly regarding management, operation, and development. All goals related to preservation and conservation, as well as marketing and promotion, must be effectively communicated among stakeholders. The way in which Omani visitors perceive ecotourism is heavily influenced by economic considerations. Although ecotourism is viewed positively for its financial advantages for the nation and communities, concerns remain regarding the negative impacts of tourism development on the environment. It is therefore essential to focus on promoting sustainable growth in these areas without compromising the environment.
Increasing the User Experience Research Maturity of a Global Accommodation Comparison Platform
Authors: Pretorius Marco , Penkert Lydia Christine
Published: May 2023

The COVID-19 pandemic drastically impacted the travel industry. Additionally, the recent combination of a sociopolitical crisis, natural disasters and an economic crisis resulted in increased price sensitivity and consciousness in consumer spending. However, the travel industry continues to recover as more countries ease travel restrictions. As travel volumes gradually increase in many parts of the world, product development teams focusing on the User Experience (UX) of travel websites are critical for user satisfaction and business success. User-centric design is the process of building a product or service based on the wants, needs and challenges of the users. However, being truly user-centric requires an active means of listening to users through UX research methods. When implementing such methods, organisations typically transition through different stages of UX research maturity; namely, from the beginning stages where there is a lack of resources and ad-hoc implementation, to a mature state where user research informs business strategy. This case study focuses on practice-based insights of methods used to increase the UX research maturity of an online accommodation comparison platform in the travel industry. The study covers a period of two years, analysing the outcome of the methods introduced to increase the UX research maturity. The case study aimed to achieve the following to increase the maturity: creating awareness of UX Research and the user; exposing UX Research to the wider team; and extending research ownership to product teams. The methods used included: diary study; jobs-to-be-done framework; organisational structural changes; involving product team members in research activities; increasing the frequency of interviews with users; and enabling the product team to conduct small research activities. The results included an increase in the UX Research maturity of the organisation. The product development approach increased its user-centric focus. Non-UX roles within the product team grew closer to the user by doing small research activities. User-centricity was introduced as a company value in the organisation. The results of this study are specifically of value for practitioners and academia in the travel industry and have implications for Product, UX and Research practitioners.

Evaluation of turn-off dV/dt controllability and switching characteristics of 1.2 kV GaN polarisation superjunction heterostructure field-effect transistors
Authors: Sheikhan Alireza , Madathil Sankara Narayanan Ekkanath , Kawai Hiroji , Yagi Shuichi , Narui Hironobu
Published: May 2023

Gallium nitride (GaN) devices inherently offer many advantages over silicon power devices, including a higher operating frequency, lower on-state resistance and higher operating temperature capabilities, which can enable higher power density and more efficient power electronics. Turn-off dV/dt controllability plays a key role in determining common-mode voltage in electrical drives and traction inverter applications. The fast-switching edges of GaN can introduce challenges such as electromagnetic interference, premature insulation failure and high overshoot voltages. In this paper, the device working principle, characteristics and dV/dt controllability of 1.2 kV GaN polarisation superjunction (PSJ) heterostructure FETs (HFETs) are presented. The effect of gate driving parameters and load conditions on turn-off dV/dt are investigated. It is shown that in PSJ HFETs the dV/dt can be effectively controlled to as low as 1 kV μs−1 by controlling the gate, with a minimum increase in switching losses. These results are highly encouraging for the application of the devices in motor drives.

Authors: Kosmacheva N. M. , Cherkasskaya G. V.
Published: May 2023

Aim. To determine the possibility of assessing the energy management of municipalities as an in­dicator of differentiation of municipal districts by quality of management in the Leningrad region.

Tasks. To describe the energy capacity of the Leningrad region; to assess the impact of energy management as a management practice on the differentiation of municipal districts in terms of management quality; to compare the quality of general management and energy management in municipal districts.

Methods. The authors used modern methodology of socio-economic research, including the ap­plication of system and process approaches, the method of comparative analysis.

Results. A mismatch was found between the overall quality of management (in terms of assessed results) and the quality of energy management in municipal districts.

Conclusions. According to the author's position, the uneven quality of management in munici­pal districts is obvious. The necessity of introducing into the practice of municipal management of the Leningrad region of the Russian Federation (RF) a more responsible approach to solving the problem of improving the energy efficiency of the regional socio-economic system as a goal of energy management, which should be seen as a means to improve the system of public pro­duction (goods and services) and improve the quality of environment and life of the population in the region under study.

Published: May 2023

Aim. To develop guidelines and instruments of the stimulating monetary policy of the Russian Federation (RF), contributing in the conditions of the sanctions imposed to increase the rate of economic growth and its efficiency.

Tasks. Analysis of the state of the Russian economy, the main directions of its further de­velopment and regulation mechanisms; study of the financial potential of the Russian econ­omy (savings and investments) in conditions of closing access to financial markets and to in­ternational payment and settlement systems of developed countries; study of the ongoing monetary policy of Russia, its main components — monetary and fiscal policy, their impact on economic growth; analysis of modern monetary theory, existing views of Russian and for­eign economists

Methods. The authors applied the method of analysis in the process of studying the practice of monetary and fiscal regulation in Russia and abroad, carried out economic analysis. The ar­ticle reflects the research data of Russian and foreign specialists. A systematic approach, which provides for the interdependence of monetary, fiscal policy and macroeconomic regulation of the economy, investment and innovation development, was used.

Results. The need to combine the ongoing restraining anti-inflationary monetary policy with a soft budget policy, providing incentives for modernization of enterprises, domestic demand and supply at the expense of targeted budget financing within the adopted state programs of socio-economic, structural and innovative development with reasonable limits of budget deficit and public debt has been established.

Conclusions. In a stagflationary environment, it seems appropriate to pursue a strict anti- inflationary monetary policy of the Bank of Russia, restraining credit issuance and stimulat­ing the growth of savings. Closed access of RF residents to financial markets of developed countries with excessive monetary resources, limited opportunities for growth of domestic savings and savings, insufficient inflow of foreign investments due to high risks of Russian residents to foreign markets increases the importance of targeted budget financing in the context of state programs to expand and modernize production, structural reforms and in­novation development. To justify the limits of the deficit of state and municipal budgets and debts, it is necessary to apply the indicators of fiscal gaps. As the key rate of the Bank of Russia decreases, the financial market stabilizes, and the targets of targeted programs are met, budget financing is replaced by private investment, bank and commercial lending.

Published: May 2023

Aim. To find and argue points of growth of additive manufacturing, as well as to justify the rel­evance and significance of new business models using digital platforms.

Tasks. To consider the features of management of digital additive manufacturing; to analyze the reasons for the low rate of additive technology development; to show the prospects of dig­ital development of additive manufacturing; to justify the importance of digital platforms for additive services as a new business model and prove that digital additive manufacturing can be characterized as a system innovation.

Methods. General scientific methods (analysis, synthesis, monographic, grouping) were used in the research. The best Russian and world practices, fundamental and applied works of na­tional and foreign researchers, scientists, practitioners in the field of management, digital transformation were studied using the search of relevant research in open sources, both in ge­neral purpose search engines, and in specialized search engines and databases.

Results. It is proved that digital additive manufacturing should be regarded as a system in­novation, and its large-scale benefits can be realized if the technology is complemented by va­rious innovations in products, processes and services. From the author's point of view, the po­tential and prospects of a new business model in the online market of additive design and manu­facturing are obvious: a digital platform of additive services for manufacturing parts from various materials.

Conclusions. Additive manufacturing plays a vital role in Industry 4.0 because of the shortened cycle time of the lean process and the high degree of decentralization of production processes. Therefore, a systematic approach using digital platforms is required to unlock their capabilities. Customers who require parts produced using this technology can place their designs on a plat­form and find a manufacturing partner based on available technical resources, geographic loca­tion, and the amount of anticipated cost. Implementing a digital platform design strategy that integrates all stages of the design and production process for different products, facilitates data traceability and product reproducibility on different additive manufacturing machines, greatly increases customer value.

SODIUM CHANNELOPATHIES: A REVIEW
Authors: Usha Rani M. , Revathi Mudduluru , Shanmukh Vemparala Sai
Published: May 2023

Introduction: Sodium channelopathies are a group of genetic disorders characterized by abnormalities in sodium channels that can cause a wide range of cardiac and neurological symptoms. These disorders can be inherited in an autosomal dominant pattern and can be caused by mutations in various genes, including SCN5A, SCN1B, and SCN2B. A comprehensive literature search was conducted using PubMed, MEDLINE, and Google Methodology: Scholar to identify relevant articles published from March 2005 to November 2021. The following keywords were used: "sodium channelopathies", "sodium channels", "sodium channelopathy genetics", "sodium channelopathies-pathophysiology", "sodium channelopathies- their clinical presentations and management". Only articles written in English and reporting on human studies were included. The clinical presentation of these disorders can vary widely, Clinical features and management: ranging from asymptomatic to sudden cardiac death, and can be inuenced by factors such as age, gender, and comorbidities. Genetic testing can aid in the diagnosis and management of these disorders, and there are several treatment options available, including medications, implantable cardioverter-debrillators, and lifestyle modications. Conclusion: While signicant progress has been made in our understanding of sodium channelopathies in recent years, there is still much to learn about these complex disorders. Further research is needed to fully elucidate the underlying mechanisms of these disorders, identify novel therapeutic targets, and improve clinical outcomes for affected individuals. Nonetheless, the knowledge gained so far has provided valuable insights into the pathogenesis and management of these disorders, and has the potential to greatly improve the lives of those affected by sodium channelopathies.
Optimal Querying for Communication-efficient ADMM using Gaussian Process Regression
Authors: Duarte Vera Tudela Aldo , Nghiem Truong , Wei Shuangqing
Published: May 2023

In distributed optimization schemes consisting of a group of agents connected to a central coordinator, the optimization algorithm often involves the agents solving private local proximal minimization sub-problems and exchanging data frequently with the coordinator to solve the global distributed problem. Such schemes usually cause excessive communication costs to the system, leading to the need for communication reduction for scenarios where communication is costly. The integration of Gaussian Processes (GPs) as a learning component to the Alternating Direction Method of Multipliers (ADMM hase been proven successful in learning each agent’s local proximal operators. Consequently, such a learning technique is effective to reduce the communication between the agents and the coordinator. A key element for the integration of GP in the ADMM algorithm is the mechanism upon which the coordinator decides when communication with an agent is required. The decision strategy used in this setting strongly affects the overall communication expenditure reduction and the ADMM’s algorithm performance. For that reason, we construct a general framework presenting a systematic querying mechanism as an optimization problem that balances the ideas ofmaximizinge the communication cost reduction while minimizing the prediction error. Motivated by such a framework, we propose different query strategies using the uncertainty measurement given by GP, to determine if the prediction is reliable enough to skip a communication round. We propose a joint query strategy following a simplification of the general framework that minimizesana L1 norm communication cost constraint by the trace of the joint uncertainty of the ADMM variables which is calculated using all agents’ prediction uncertainty. Additionally, we derive three different decision mechanisms (motivated by a confidence interval analysis) that make their decision by analyzing an uncertainty measurement for each agent individually. We integrate multiple measures to quantify the trade-off between the communication cost reduction and the optimization solution’s accuracy/optimality. The proposed methods can achieve significant communication reduction and good optimization solution accuracy for distributed optimization, as demonstrated by extensive simulations of a distributed sharing problem with quadratic cost functions for the agents. 
Segmentation Effects in the Modular HVDC Offshore Wind Generator and its Impact on Losses
Authors: Karekezi yannick , Zhang Zhaoqiang , Olsen Pål Keim
Published: May 2023

Worldwide wind power capacity jumped from 7.5GW in 1997 to 564GW by 2018, according to IRENA. Many regions of the world have strong wind speeds, but the best locations for generating wind power are often remote, where offshore wind power offers tremendous potential. This paper presents a concept to remove the use of offshore platforms/substations, constituting the energy conditioning element for high voltage direct current (HVDC) transmission. Instead, it connects converters in a series of modules for a segmented HVDC generator, which limits the number of conversion steps. Our work focuses on the impact of segmentation on loss and is validated numerically using finite element analysis (FEA) and analytical solutions. The machine’s geometry, design constraints, design procedure, loss calculations, and numerical analysis are included. Three different methods are presented and used to determine the core losses. The paper highlights the increase in core losses due to airgap segmentation. We show that Zhang’s method yield the largest deviation in the loss calculations, i.e., 15.812%, 16.410% and 15.894% increase in core losses for 10, 20 and 30 mm segment airgaps, respectively.
Small-Signal Stability Enhancement of Power Grids via Optimally Coordinating Inverter-Based Resources
Authors: Yuan Hui , Li Zhiyi , Li Shiyang , Gao Huisheng
Published: May 2023

The growing penetration of inverter-based resources (IBRs) that synchronize with the power grid through phase-lock loops (PLLs) has caused a set of small-signal stability issues. Commonly, these issues can be addressed by refining controllers’ design of IBRs, which however fails to be effective when power grids are operating under critical conditions. To this end, this paper presents a novel optimization model for coordinating active power outputs (i.e., operation adjustment) of IBRs while satisfying small-signal stability constraints (SSSCs). In particular, SSSCs are formulated based on a new metric that quantifies the small-signal stability from the viewpoint of grid strength, which is especially suitable for those “black-boxed” IBRs. To reduce the problem-solving complexity due to the inherent discontinuity and nonlinearity, a sequential solution approach is proposed to decompose the original optimization problem into a sequence of sub-optimization problems (SOPs). Also, a dynamical-region-adjustment method and a convex-relaxing method are integrated to ensure the existence of feasible solutions and further enhance the solution efficiency. Finally, the performance of the proposed method is verified based on a 11-IBR test power system. 
Wie zichzelf privatiseert kan wereldburger zijn: Over burgerschap, integratie en ander fraais: drie problemen
Authors: Blommaert Jan
Published: May 2023

De context van dit stuk is snel geschetst. Gedurende decennia heeft men zowel in onderzoek als in beleid het ‘etnische minderheden-model’ aangehangen, waarbij ‘integratie’ de voornaamste vector was waarlangs de multiculturele samenleving gestalte zou krijgen. In het laatste decennium merkt men een zekere verstrakking van dit integratiemodel, en het model krijgt geleidelijk ook een nieuwe naam: ‘inburgering’. De nieuwe naam verbergt een impliciete theoretische verschuiving van collectieve visies op integratie (integratie was een groepsproces, dat zich bijvoorbeeld via verschillende allochtone ‘generaties’ voltrok) naar meer individuele visies. Inburgering is een individueel ‘gelijke kansen-traject’, en sluit in die zin aan bij andere brede en consensuele verschuivingen in het politieke en sociale vertoog en in de structuren, en vindt zo aanhechtingspunten bij zowel liberale als christen- en sociaal-democratische programma’s.
Meedoen versus zelf doen: Zin en onzin van stads-, buurt- en straatburgerschap
Authors: van der Zwaard Joke
Published: May 2023

Stadsburgers zijn trots op hun stad, kennen hun rechten én plichten, voelen zich verbonden met de stad, uiten dit in participatie en onbetaalde activiteiten en gaan op een respectvolle manier met elkaar om (gemeente Rotterdam 2007). Stadsburgerschap en straatburgerschap zijn door bestuurders, beleidsmakers en wetenschappers om diverse redenen omarmd als pragmatisch alternatief voor het cultureel geladen en beladen staatsburgerschap. Allereerst omdat het beter lijkt te werken: de Erasmusbrug is een effectiever identificatiemiddel dan het Wilhelmus. Immigranten en hun nazaten blijken zich sneller te identificeren met hun woonplaats dan met hun nieuwe land (Phalet et al. 2000). Terwijl op landelijke schaal de wij-zij-tegenstellingen (arm-rijk, hoogopgeleid-laagopgeleid, autochtoon-allochtoon/ islamitisch, de culturele elite-henk&ingrid) onoverbrugbaar lijken, blijken mensen op straatniveau ondanks verschillende afkomst en positie gezamenlijke problemen te kunnen formuleren en oplossen; al of niet met hulp van een opbouwwerker (Duyvendak & Uitermark 2006). Er is zelfs al een woord uitgevonden voor dit productieve burgerschap in wijken en buurten: de ‘doedemocratie’ (Van de Weijdeven & Hendriks 2010). Voormalig minister Donner van Binnenlandse Zaken, waaronder ‘de wijken’ tegenwoordig vallen, kondigde aan dat hij dit ‘moderne burgerschap’ wilde ondersteunen door de ‘bewonersbudgetten in wijken’ te verruimen (Donner 2011).

Authors: Ünal Elif , Öztürk Bilgin , Şimşek Uğur Burak , Sonkaya Ali Rıza , Karadaş Ömer
Published: May 2023

Objective: Coronavirus-2019 (Covid-19) was first observed in December 2019 and recognized as a pandemic by the World Health Organization. Apart from respiratory symptoms, neurological, dermatological, and gastrointestinal symptoms can also occur in humans. Some neurological symptoms may be caused by microembolism. The present study aims to determine the presence of microemboli in patients with Covid-19 using Transcranial Doppler (TCD) ultrasonography and examine its correlation with D-Dimer levels.
Material and Methods: This study involved 20 hospitalized patients diagnosed with Covid-19 using the Polymerase Chain Reaction (PCR) method. D-Dimer results of the patients were recorded and analyzed within two groups (First group: D-Dimer < 1 mg/L, and second group: D-Dimer ≥ 1 mg/L). The middle cerebral arteries were bilaterally examined with TCD to screen for microemboli. Patients were classified into two groups based on the number of MES (first group: 0-3 MES (n=10), second group: ≥ 4 MES).
Results: Cerebral arterial microemboli were observed in patients with Covid-19. The relationship between D-Dimer and emboli was investigated, and the presence of microemboli was found to be statistically significant in both the low D-Dimer value group (p < 0.001) and the high D-Dimer value group (p < 0.003). Furthermore, D-Dimer results were found to be higher in the group with a greater number of microemboli (p < 0.001).
Conclusions: Microemboli were detected in the cerebral arteries of Covid-19 patients, even in the absence of neurological symptoms. Additionally, a positive correlation was observed between high D-Dimer levels and the presence of cerebral microemboli. Therefore, physicians should assess the presence of microemboli in Covid-19 patients and determine appropriate treatment methods accordingly.
