A Ciência da Informação e a Relação com a Ciência da Administração à Luz de uma Possível Interdisciplinaridade
Authors: Lima Leandro Cearenço , Campos Andréa Fraga Dias , Gosling Marlusa de Sevilha , Ferreira Eric de Paula , Corrêa Fábio
Published: October 2022

De domínio vasto e complexo, a relação entre campos distintos é um tema marcante nas ciências, difícil de ser estabelecida objetivamente, se dá por aproximações e características comuns. O objetivo da pesquisa consiste em analisar as origens, características e principais concepções que possibilitem a interdisciplinaridade entre os campos da Ciência da Informação e da Ciência da Administração.  A pesquisa tem natureza exploratória com abordagem qualitativa e se caracteriza como revisão bibliográfica que foi dividida em duas etapas, sendo que, a primeira foi de conscientização e levantamento do problema teórico inicial e a segunda na busca sistematizada de artefatos. A rigor, foi possível identificar as origens históricas e concepções em comum, bem como, traçar em linhas gerais as principais características que permitiram a possibilidade de interdisciplinaridade. Evidencia-se que a natureza interdisciplinar entre os dois campos ocorre por um processo de troca de saberes e de interação que navega por problemas básicos comuns do comportamento informativo humano. Também, pode-se inferir que os campos apresentam aproximações claras, e embora o rol de autores elencados apontem de forma uníssona para uma forte relação interdisciplinar baseada na “informação”, ao que parece, quando se trata da aplicação prática, não há consenso que essa interdisciplinaridade seja completa.

Authors: Dlamini Khanyile , Grace Jeanne
Published: October 2022

Noncommunicable diseases (NCDs) continue to be a global public health challenge for both developed and low and middle-income countries, with inactivity, overweight and obesity contributing to mortality. The study aimed to determine the body mass index (BMI), objectively measured physical activity (PA) levels, and socio-economic status (SES) of Zimbabwean adolescents and to establish the associations between their BMI and their PA and SES, and between their PA and their SES. Participants (N=126) aged 12−19 years were included in the study. BMI was classified according to the WHO BMI z-scores. Participants’ PA levels were measured with a pedometer. SES was determined with the Family Affluence Scale III. The groups’ mean BMI was 20.45 kg/m2, with 18.9% of the females and 11.5% of the males being overweight. The groups’ mean average number of steps taken per day for seven days was 9 459, and their SES was classified as low. The association between the males, females and groups’ BMI with their PA levels was insignificant, negative and weak. There was a significant positive, weak association between BMI and SES for the males (r = 0.289; p < 0.05) and the group (r = 0.227; p < 0.05). The association between the females' PA and their SES was significant, negative and weak (r = -0.338; p < 0.05) with a significant, negative and moderate association between the males’ PA and their SES (r = -0.448; p < 0.05). The higher the participants' BMI, the higher their SES, and the higher their PA levels, the lower their SES.

En la bimilenaria historia de la Iglesia, las mujeres han ocupado un puesto marginal. Sin embargo, algunas de ellas han destacado sobremanera y han sido ejemplos y testimonios de vida en los siglos que les tocó vivir. En el mundo de la catequesis, la mujer ha sido la gran protagonista y lo sigue siendo. Las madres, las abuelas, las catequistas han transmitido y siguen transmitiendo la fe a las nuevas generaciones. Sin embargo, la reflexión catequética ha sido “cosa de hombres”. Pocas mujeres catequetas se encuentran en los libros especializados de catequética o historia de la catequesis. El autor del artículo presenta a tres mujeres que, a pesar de las dificultades, fueron pioneras en un mundo muy masculino. Conoceremos su interesante biografía y las aportaciones catequéticas que realizaron.

Heterogēnas svešvalodu klases – universāla problēma Latvijas vidusskolās: izaicinājumi un risinājumi
Authors:   Majoru vidusskola, Gaugere Kristīne , Rektiņa Andra ,   Rīgas Angļu ģimnāzija
Published: October 2022

According to data from the National Educational Content Centre, in the school year 2019/2020, only about 30 % of the students completing the centralised exam in English reached level B2, which is set as a goal in the educational standard. When analysing the results of the examinations in different schools and applying statistical deviance calculations, the authors concluded that there is a significant difference in the level of knowledge within the same class in all Latvian secondary schools, apart from state gymnasiums. The difference between the levels of knowledge is so vast, that effective learning is rendered virtually useless. In the second part of the article, the authors study how to ensure meaningful learning in heterogeneous classes, and when analysing the benefits of internal and external differentiation, as well as the different aspects of motivation, it is concluded that external differentiation, as well as setting an attainable goal that is personalized to each individual students existing level of knowledge, are optimal methods for effective learning in highly heterogeneous classes. In conclusion, the authors offer recommendations to foreign-language teachers and highlight topics for further discussion. 1. Evaluation of students’ knowledge level has to become the first step in the planning of foreign-language teaching. 2. Once the students’ level of knowledge has been evaluated, the teacher can effectively produce realistic goals for the students. 3. The teacher chooses the appropriate mode of differentiation (inner or outer) based on the students outlined goal. 4. The teacher assesses the students; both in regard to summative and formative assessments, purely based on the students’ outlined goals, regardless of their compliance with the educational standard. Two important topics can be brought to contention and further discussion, the first one being a more practical one, linked to the wider use of external differentiation in classrooms with students representing significant variances in their knowledge level, and the other a more philosophical point, linked to our students’ potential vision of themselves as language users and the compatibility of this vision with the language learning objectives expressed in the educational standard.

Authors:   Siauliai Academy of Vilnius University, Būdvytytė Aina
Published: October 2022

In diesem Beitrag geht es um Herausforderungen und Realisierungsmöglichkeiten der fächerübergreifenden Integration im aktualisierten allgemeinen Curriculum für die zweite Fremdsprache an litauischen Schulen. Die Analyse unterschiedlicher Teile des Curriculums zeigt, dass es verschiedene Möglichkeiten für fächerübergreifende Integration bietet und so die Grenzen des üblichen Fremdsprachenunterrichts erweitert bzw. aufhebt. Die fächerübergreifende Integration umfasst vielfältige Kombinationen von Themenbereichen, Methoden und Fächern, die durch ein themenzentriertes Problem bedingt sind. Dies heißt aber nicht, dass die Lehrkraft jedes Mal das Rad neu erfinden muss. Die Lehrwerke für DaF sind kontextuell und integrieren zahlreiche Fachtexte, die dem Sprachniveau der Lernenden entsprechen. Der CLIL Unterricht bietet im Fall der themenzentrierten Integration die Möglichkeit, das Sprach- und Fachlernen gegenseitig zu ergänzen, und verändert die Kultur des Lehrens und Lernens in der Schule.
Spāņu valodas apguve Latvijā: pašreizējās situācijas raksturojums
Authors:   University of Latvia, Liepa Zenta
Published: October 2022

With its ever increasing number of speakers, Spanish, being one of the so-called major languages of the world, has overtaken English in terms of native speakers in recent years, now ranking second behind Chinese, and its growing popularity and expansion can be felt in Latvia as well. In recent years it is evidenced by an increase in translations of original works into Latvian, cinema and theatre performances, rapid growth of various Spanish companies and, undoubtedly, the interest of the residents of Latvia, particularly young people, in learning Spanish. In Latvia, Spanish can be learned in general education schools, starting from Form 6; it is more popular among secondary school pupils, as evidenced by the number of general education schools: in academic year 2018/19 Spanish could be learned in 18 general education schools, while in academic year 2019/20 there were 16 education institutions offering the language. Moreover, the capital of Latvia is not the only place where Spanish is taught as a second or third foreign language: everything depends on the opportunities provided by each individual school. In total, there were 32 schools in Latvia where Spanish was taught as the third or even the fourth foreign language during last academic year. To obtain secondary education in Latvia, one of the centralised exams has to be taken in a foreign language; English is the most popular choice among schools. Those who wish to obtain a certificate in Spanish can do so at the Instituto Cervantes DELE examination centre, which has been operating at the Latvian Academy of Culture since 2004. The centre offers an opportunity to take exams at 6 levels and obtain the internationally recognised DELE diploma, certifying the examinee’s Spanish knowledge and skills. Spanish can also be learned in courses and at language centres irrespective of the students’ age and previous knowledge. Picasso and Seneca, two private Spanish language centres, have been successfully operating in Latvia for more than 10 years, and their students range from pupils to seniors. Bachelor students learn Spanish at the Latvian Academy of Culture in the Latvia-Spain Cross-Cultural Communication programme; however, they do not obtain a qualification in philology. Master students can learn Spanish as part of the Romance Language and Culture Studies study programme at the University of Latvia, and the language is also offered as an elective course at other higher education institutions in Latvia. Unfortunately, systemic Spanish acquisition and programme continuity is hindered by the lack of a Spanish philology bachelor study programme at the University of Latvia. The paper focuses on Spanish learning traditions, issues, and future opportunities in Latvia, drawing upon data available in the state education system and interviews with industry experts: officials, educators, and translators.

Published: October 2022

Each generation has its own significant contribution, Adolf Ferrier (1879–1960) and his contemporaries, prominent personalities have left the influence on teaching-learning process. The issues of individualized learning, how to work with gifted students, how to organize project work are still relevant, so the article pays in-depth attention to these three aspects. The purpose of this article is to update the ideas and tasks of the active school, which gained wide international recognition in the 1920s of XX century. Generations are formed, firstly, by educational beliefs and, secondly, by technologies that influence attitudes, perceptions, as well as collaborative skills and lead to find a suitable form of communication. Understanding of different personality types provides clarity, allows to accept different attitudes, behaviours, helps to improve communication and mutual understanding, provides the opportunity to apply appropriate learning content with the opportunity to express their talents, develop strengths and work on weaknesses. An active school promotes to go deeper, to see the potential of student, setting a specific goal at work, creates a habit of proper work performance, demands the completion of the work started, leading to the result. A retrospective view of history gives impetus to the methods for creative learning content, calling for the unconscious to be made conscious, emphasizing the importance of forming habits.

APPLICATION OF LINE SURGE ARRESTERS IN THE PROTECTION OF THE 110 kV STON – KOMOLAC TRANSMISSION LINE FROM ATMOSPHERIC DISCHARGES
Authors: Miroslav Mesić  , Milan Puharić  , Dalibor Škarica
Published: October 2022

The reliability of the operation of a transmission network largely infl uences the reliability of the power system and the security of the electricity supply to consumers. During the past 10 years, there have been a large number of outages of the 110 kV Ston – Komolac Transmission Line due to its specifi c location in a zone where the intensity of atmospheric discharge is high, which has thereby signifi cantly reduced the reliability and security of the operation of that section of the transmission network. As the most technically and economically desirable solution for improving the protection of the transmission line from atmospheric discharges, it was decided to equip the transmission line with line surge arresters. Their installation signifi cantly reduced the number and duration of forced outages and increased the reliability of the transmission network in the greater Dubrovnik region. Equipping the transmission line with line surge arresters was the basis for a pilot project of monitoring the operation of the transmission line during atmospheric discharges. The experiences and results regarding the effi ciency of the protection of the 110 kV Ston – Komolac Transmission Line from atmospheric discharges will provide the basis for further applications on transmission lines of higher voltage levels.
DETERMINATION OF THE MUTUAL GROUND RESISTANCE OF ADJACENT GROUNDING GRIDS
Authors: Ivan Sarajčev  , Petar Sarajčev  , Slavko Vujević
Published: October 2022

The article discusses the determination of the mutual ground resistance of two adjacent metallically connected grounding grids. For this purpose, an original analytical expression for calculating the corresponding mutual ground resistance of two adjacent grounding grids has been developed. There is a complex electromagnetic coupling between adjacent grounding grids. The conductive component of this coupling is particularly evident. During a ground fault, this component markedly increases the ground resistance of the corresponding grounding system. It is essential to establish the aforementioned mutual ground resistance correctly in order to determine the distribution of the partial ground fault currents in a system of adjacent grounding grids. The determination of mutual ground resistance is presented using two specifi c grounding grids buried in poorly conductive soil.
REACTIVE POWER MARKET MODEL BASED ON THE DIVISION OF THE ELECTRIC POWER SYSTEM INTO VOLTAGE ZONES AND ON THE TWOLEVEL OPTIMIZATION ALGORITHM
Authors: Tomislav Plavšić  , Igor Kuzle
Published: October 2022

The article presents a reactive power evaluation methodology which in terms of time comprises the action of the reactive power market in the stage of short-term planning. The methodology is based on the division the electric power system (EPS) into voltage zones by using the electrical distance method, whereby local reactive power markets are established. Within each local market a separate TSO cost optimization is performed by means of the optimal power flow applying the criterion of minimal required payment for reactive power. The said optimization is the first step within a developed methodology, the purpose of which is to determine the share of each of the available control systems in reactive power generation within each of the established zones. Based on optimal reactive power generation, an auction procedure is conducted by which a uniform price of reactive power generation within a zone is defined. In the second optimization step the optimization of the whole network is carried out by the criterion of minimal energy procurement costs to cover the network losses and simultaneously by the criterion of minimal reactive energy procurement costs, using the optimal power flow. The methodology has been tested on the Croatian EPS model for the maximum network load scenario. The proposed approach is warranted by the results, whereas the detected problems can at once serve as guidelines for future development and potential improvements in the proposed methodology.
THE CRITERIA AND METHOD OF DEFINING PRIORITIES FOR THE REVITALIZATION OF THE TRANSMISSION NETWORK
Authors: Davor Bajs  , Matislav Majstrović
Published: October 2022

The work examines the problem of the aging of transmission network units and the impact of it on the reliability of the electric power system (EPS). The criteria and methodology are defined for compiling a priority list for the revitalization of lines and transformers in transmission networks. The criteria are based on the real condition of a unit and the role and relevancy of the unit within the EPS. Through a probabilistic simulation and a multi-scenario analysis the expected annual operating costs of the system are calculated. Based on the difference of these costs at different unavailability levels of the observed units, the individual criteria, which are dependent on the role and relevance of the observed unit, are quantified and the significance index of the revitalization candidates is calculated. Based on that index, and the condition index of individual revitalization candidates, a single priority list of lines and transformers for revitalization is compiled.
REGULATION OF ELECTRICITY SUPPLY QUALITY AS A NECESSARY FUNCTION IN THE REGULATION OF MONOPOLY SERVICES
Authors: Ivona Štritof  , Slavko Krajcar
Published: October 2022

The article analyzes the shortcomings of price regulation as a function in the regulation of the monopoly activity of electricity distribution that does not include the quality regulation of electricity supply. Also analyzed is a conceptual model for launching an electricity supply quality regulation system with special emphasis on the reliability of supply as the crucial aspect of supply quality regulation. Developing the continuity of supply regulation will ultimately facilitate the introduction of an integrated regulation model comprising electricity price and electricity supply quality. The article also describes the experiences of the Hungarian regulatory authority in stepby- step introduction of price regulation and in integration of supply quality into the price regulation model.

Published: October 2022

The Andromeda galaxy (M31) is an object of ongoing study with the Ultraviolet Imaging Telescope (UVIT) on AstroSat. UVIT far-UV (FUV) and near-UV (NUV) photometry is carried out here for a set of 239 clusters in the NE disk and bulge of M31 that overlap with the HST/PHAT survey. Padova stellar models were applied to derive ages, masses, metallicities, and extinctions for 170 clusters. The ages show a narrow peak at ∼4 Myr and a broad peak around 100 Myr. log(Z/Z
⊙) values are mostly between −0.3 and +0.3. The 7 clusters in the bulge have a low metallicity and high mass. Most clusters are in the spiral arms and have metallicities in the range noted above. The youngest clusters mostly have high metallicity and are concentrated along the brightest parts of the spiral arms. The UVIT FUV and NUV data are sensitive to young stars and detect a new metal-rich peak in star formation in the disk at age ∼4 Myr.

Additionally, lectotypification of three names, R. davidianus Kuntze, R. malifolius Focke and R. viburnifolius Franch., are designated here after examination of previous works.
Clinical Implication of Molecular Tumor Board
Authors: Lee Soohyeon
Published: October 2022

Due to rapid technical advances, steeply declining sequencing costs, and the ever-increasing number of targeted therapies, it is expected that extensive tumor DNA or RNA sequencing will be applied in standard of care. Clinicians will thus be confronted with increasingly complex genetic information and multiple test-platforms to choose from. General medical training, meanwhile, can hardly keep up with the pace of innovation. Consequently, there is a rapidly growing gap between clinical knowledge and genetic potential in cancer care. Multidisciplinary Molecular Tumor Boards (MTBs) have been suggested as a means to address this disparity, as a multidisciplinary approach to keep pace with the growing knowledge of complex molecular alterations in patients with advanced solid cancer. MTBs are designated to interpret these data and provide clinical recommendations. Not all patients with cancer have access to advice of an MTB. We aimed to determine the current status, opportunities, and challenges of the organization of MTBs in the Korea.

IMPROVING HUMAN-CENTRED DESIGN APPLICATION IN THE MARITIME INDUSTRY – CHALLENGES AND OPPORTUNITIES
Authors: Vu V D , Lützhöft M H
Published: October 2022

Ergonomic issues with the design of ships and on-board equipment have been reported to hinder the crew’s performance, increase the chance of erroneous actions and, consequently, lead to negative outcomes of maritime operations. One solution to such issues is following a human-centred approach in system design and evaluation, which helps improve usability. While being widely applied in other sectors such as in designing aviation systems, medical equipment, or consumer electronics, HCD practice is still limited within the maritime field.
Acknowledging this issue, the Nautical Institute organised a focus group with the participation of 78 people representing various maritime stakeholders. The participants jointly discussed and proposed solutions to improve HCD adoption in the maritime industry. Proposed solutions were aimed toward promoting awareness of usability and HCD among all stakeholders, increase HCD practices through regulatory documents, provide means to support designers in adopting HCD, and introducing a sector-based strategy to adopt HCD.

Shock and vibration exposures in fast boats at sea can be more severe than in any other mode of transport. Shock mitigation seating plays a key part in reducing the possibility of injury, but seats must be suitable for the boat and for the way the boat will be used.
The RNLI recently conducted an innovative sea trial programme to assess the performance of eight seats, from three manufacturers, for use in the Severn Class all-weather lifeboat. The trials were designed to maximise data capture while minimising crew exposure. Seat performance was measured with a range of occupants and operating conditions and the final seat selection was based on analysis of over 2,500 wave impacts. These “wave by wave” trials involved normal boat operation and were much more efficient to carry out than the more conventional, but often impractical, approach of attempting to carry out controlled, timed runs at specific speeds in specific sea states.
Ahead of the trial, the seat manufacturer used information on RNLI crew demographics and craft operating conditions to optimise the seat. The seat configuration was determined from laboratory drop-tests at their in-house facility, with parameters chosen that were most likely to perform well in the Severn. The laboratory test procedure followed the methods defined by the UK's Ministry of Defence Protocol 1&2 and the US Navy's NSW/CCD-080-TR-2015/010 seat
testing requirement.
This paper describes the sea trials approach and seat design optimisation that led to the selection of the seat for use in the Severn Class.
ANOTHER SERIES OF UNFORTUNATE EVENTS: A FAILURE OF SITUATIONAL AWARENESS
Authors: Cook M J
Published: October 2022

In the Human Factors literature there is now a very sophisticated understanding of human factors engineering and how control teams function. In particular the differentiation of technical and non-technical skills and their role in supporting
effective control team performance has been outlined. Many of the significant changes have come from the aviation industry and other application domains, like maritime, are attempting to catch up. However, there is a dearth of detailed information in maritime because unlike aviation the use of cockpit voice recorders and other detailed recording of platform behaviour is not necessarily mandated or recorded. Training simulators offer a good opportunity to explore these issues but in the absence of an adequate quality of training evidence, accident reports provide an insight into the contribution of human factors issues, technical and non-technical, to incident development and accident sequences. As pointed out in earlier papers commercial shipping is not immune to these issues associated with human performance and technology interactions, with incidents such as the Viking Sky and Savannah express indicating analogous issues. To categorise events such as those with the USS Fitzgerald, USS McCain and HNoMS Helge Insgtad as a failureof human operations is a statement of the obvious and not a guide to future improvements required to prevent recurrence.
Experimentation and Approval Mechanisms
Authors: McClellan Andrew
Published: October 2022

We study the design of approval rules when costly experimentation must be delegated to an agent with misaligned preferences. When the agent has the option to end experimentation, we show that in contrast to standard stopping problems, the optimal approval rule must be history‐dependent. We characterize the optimal rule and show the approval threshold moves downward over the course of experimentation. We find that private information may qualitatively change the optimal mechanism: an agent can choose a fast‐track option in the form of an initially depressed approval threshold. On expiry of the fast track, the threshold jumps up, introducing more stringent standards. Our results provide a theoretical foundation for both the loosening of approval standards on longer experimentation paths and fast‐track mechanisms.
Optimal Taxation of Income‐Generating Choice
Authors: Ales Laurence , Sleet Christopher
Published: October 2022

Discrete location, occupation, skill, and hours choices of workers underpin their incomes. This paper analyzes the optimal taxation of discrete income‐generating choice. It derives optimal tax equations and Pareto test inequalities for mixed logit choice environments that can accommodate discrete and unstructured choice sets, rich preference heterogeneity, and complex aggregate cross‐substitution patterns between choices. These equations explicitly connect optimal taxes to societal redistributive goals and private substitution behavior, with the latter encoded as a substitution matrix that describes cross‐sensitivities of choice distributions to tax‐induced utility variation. In repeated mixed logit settings, the substitution matrix is exactly the Markov matrix of shock‐induced agent transitions across choices. We describe implications of this equivalence for evaluation of prevailing tax designs and the structural estimation of optimal policy mixed logit models. We apply our results to two salient examples: spatial taxation and taxation of couples.
Information Hierarchies
Authors: Brooks Benjamin , Frankel Alexander , Kamenica Emir
Published: October 2022

If experiment
A is Blackwell more informative than experiment
B, it is always possible that
A and
B are induced by signals A′ and B′ such that A′ is a refinement of B′, that is, A′ entails observing B′ plus some additional information. We first show that this result does not extend beyond pairs of experiments: There exist collections of experiments that cannot be induced by a collection of signals so that whenever two experiments are Blackwell ordered, the associated signals are refinement ordered. In other words, sometimes it is impossible for more informed agents to know everything that less informed agents know. More broadly, define an
information hierarchy to be a partially ordered set that ranks experiments in terms of informativeness. Is it the case that for any choice of experiments indexed on the hierarchy such that higher experiments are Blackwell more informative, there are signals that induce these experiments with higher signals being refinements of lower signals? We show that the answer is affirmative if and only if the undirected graph of the information hierarchy is a forest.
(Auto)biografies lingüístiques en el debat públic de la transició espanyola: quins models per afrontar moments de canvi?
Authors: Iglésias Narcís
Published: October 2022

Les (auto)biographies langagières sont devenues un genre en voie d'éclosion lors de la transition espagnole, en grande partie grâce à la diffusion de différentes œuvres de Francesc Candel. Durant ces années-là, des citoyens anonymes et des représentants politiques de la quasi-totalité de l'échiquier parlementaire ont raconté leur propre autobiographie linguistique ou la biographie d'un proche pour se positionner dans le débat public et si possible, conditionner le débat politique de la période constituante (1978). Il était généralement accepté que le monolinguisme qui avait caractérisé le franquisme ne pouvait pas faire partie de l’Espagne démocratique. La transition espagnole a été une période de débats longs et variés sur les langues, produits principalement dans le domaine du journalisme et de la politique.
Uf, quin dissabte, rateta Arbequina!: una reescriptura feminista del conte tradicional català La rateta que escombrava l’escaleta per Maria-Mercè Marçal
Authors: Frayssinhes Ribes Sandrine
Published: October 2022

L'œuvre de Maria-Mercè Marçal (1952-1998) est devenue une référence incontournable dans l'histoire de la poésie catalane du XXe siècle, notamment pour son engagement féministe et sa rébellion. Dans cet article, mon objectif est de présenter l'un de ses récits intitulé Uf, quin dissabte, rateta Arbequina, écrit en 1988, que l'auteure elle-même a défini comme une adaptation du conte traditionnel catalan La rateta que escombrava l'escaleta. Tout en conservant les structures du conte populaire catalan, Marçal écrit une nouvelle histoire du célèbre personnage du petit rat, un récit moderne, dont la définition se situe entre le conte merveilleux et le témoignage. Suivant le mouvement de tension entre tradition et subversion qui est constant dans son œuvre, la poétesse subvertit le conte traditionnel pour en faire un témoignage féministe du XXe siècle, fidèle à son engagement.
DHM2-TS Framework for Evaluation of Tele-Health Platforms and Solutions

Published: October 2022

The global surge in teleconsultations in response to the COVID-19 pandemic resulted in flooding of the market with multiple telemedicine solutions. This placed healthcare providers and seekers in a dilemma, as they lacked benchmarks and assessing tools to identify the appropriate solution that would satisfy their individual demands. After reviewing the existing frameworks for evaluating telemedicine solutions and platforms, both scholarly and widely known, the authors realized that they all focused on either the commercial perspective or the information management competencies of telehealth delivery systems. After establishing this research gap, a new unified integrative model suitable for assessing telehealth solutions has been proposed, which is described in this chapter. They first summarize the methodology used to develop the framework, and then the framework's various components. This framework can be used by all stakeholders of the telehealth ecosystem: healthcare providers, patients, solution providers, and policy makers.

A technology that can guarantee to help improve potency and security within the healthcare industry is blockchain. The term ‘blockchain' denotes a shared changeless record, of a sequence of transactions, each comprising one block, with the blocks being controlled along by cryptological keys. Within the simplest terms, blockchain is going to be represented as a data structure that holds transactional records and guarantees security, transparency, and decentralization. It has the potential to rework healthcare, putting the patient at the center of the healthcare system and increasing the protection, privacy, and ability of health information. Due to the reasons that are mentioned above, blockchain has gained a lot of attention from several sectors such as government, energy, finance, health, etc. This chapter attempts to provide a deeper insight by discovering the scope of blockchain in healthcare and identifying the challenges of blockchain technology in the healthcare industry.
