Authors: Abu Bakar Aisyah , Mohamed Osman Mariana , Hitam Mizan
Published: April 2020

Sustainability in well-being embodies the interconnecting course of how various systems influence each other. The more strongly individuals subscribe to values beyond their immediate interests, that is, prosocial, collectivistic and biospheric values, the more likely they are to engage in environmental behaviour. Issue: Existing research has limited evidence on specific values of Malaysian’s personality and lifestyle (PL) that have significant impact on attitude and proenvironmental behaviour (AP). Purpose: This paper aims to verify the statistical predictability of AP based on PL. Approach: Multiple Correlation and Multiple Linear Regression were carried out to assess linear associations and parameters of linear equations to predict AP components based on PL items. Findings: AP components were moderately predictable by some of the PL items. Specifically, ‘ Urging media to raise environmental awareness ’ and ‘being mindful about environmental destruction’ were the two strongest predictors of AP.

Published: April 2020

Around 2.5 billion individuals will be living in urban areas by 2050. Two out of three individuals are going to live in urban communities or other urban focuses, featuring sustainable urban planning and public services. A biophilic city concept which is a sister term of the green city innately affiliates human being to other living organisms. Apart from adhering to human needs, the concept is the economical among other green city concepts. However, biophilic city concept is still an alien term to construction players and the public. The paper aims to propose and evaluate the critical strategies for construction players in the adoption of the biophilic city concept in Malaysia. 173 respondents consisting of government agencies, developers, consultants and contractors were involved in a questionnaire survey. 81 out of 107 strategies were accepted as the critical strategies in adopting the biophilic city concept. Among the strongest strategies are (1) effective water conservation in biophilic city project; (2) acknowledging biophilic city concept adoption publicly; and (3) adequate material resource availability for the biophilic city project. These strategies fall under three different items, namely; (1) sustainability in the biophilic city project; (2) awards and recognition for biophilic city concept adoption; and (3) organisation in the biophilic city project, respectively. Commitment of all construction players are crucial crucial towards inclusive, sustainable urban planning and public services.

Authors: Slightam Cindie , Gregory Amy J , Hu Jiaqi , Jacobs Josephine , Gurmessa Tolessa , Kimerling Rachel , Blonigen Daniel , Zulman Donna M
Published: April 2020

Background

Video-based health care can help address access gaps for patients and is rapidly being offered by health care organizations. However, patients who lack access to technology may be left behind in these initiatives. In 2016, the US Department of Veterans Affairs (VA) began distributing video-enabled tablets to provide video visits to veterans with health care access barriers.

Objective

This study aimed to evaluate veterans’ experiences with VA-issued tablets and identify patient characteristics associated with preferences for video visits vs in-person care.

Methods

A baseline survey was sent to the tablet recipients, and a follow-up survey was sent to the respondents 3 to 6 months later. Multivariate logistic regression was used to identify patient characteristics associated with preferences for care, and we examined qualitative themes around care preferences using standard content analysis methods for coding the data collected in the open-ended questions.

Results

Patient-reported access barriers centered around transportation and health-related challenges, outside commitments, and feeling uncomfortable or uneasy at the VA. Satisfaction with the tablet program was high, and in the follow-up survey, approximately two-thirds of tablet recipients preferred care via a tablet (194/604, 32.1%) or expressed that video-based and in-person care were “about the same” (216/604, 35.7%), whereas one-third (192/604, 31.7%) indicated a preference for in-person care. Patients were significantly more likely to report a preference for video visits (vs a preference for in-person visits or rating them “about the same”) if they felt uncomfortable in a VA setting, reported a collaborative communication style with their doctor, had a substance use disorder diagnosis, or lived in a place with better broadband coverage. Patients were less likely to report a preference for video visits if they had more chronic conditions. Qualitative analyses identified four themes related to preferences for video-based care: perceived improvements in access to care, perceived differential quality of care, feasibility of obtaining necessary care, and technology-related challenges.

Conclusions

Many recipients of VA-issued tablets report that video care is equivalent to or preferred to in-person care. Results may inform efforts to identify good candidates for virtual care and interventions to support individuals who experience technical challenges.
The French eHealth Acceptability Scale Using the Unified Theory of Acceptance and Use of Technology 2 Model: Instrument Validation Study
Authors: Hayotte Meggy , Thérouanne Pierre , Gray Laura , Corrion Karine , d'Arripe-Longueville Fabienne
Published: April 2020

Background

Technology-based physical activity suggests new opportunities for public health initiatives. Yet only 45% of technology interventions are theoretically based, and the acceptability mechanisms have been insufficiently studied. Acceptability and acceptance theories have provided interesting insights, particularly the unified theory of acceptance and use of technology 2 (UTAUT2). In several studies, the psychometric qualities of acceptability scales have not been well demonstrated.

Objective

The aim of this study was to adapt the UTAUT2 to the electronic health (eHealth) context and provide a preliminary validation of the eHealth acceptability scale in a French sample.

Methods

In line with the reference validation methodologies, we carried out the following stages of validating the scale with a total of 576 volunteers: translation and adaptation, dimensionality tests, reliability tests, and construct validity tests. We used confirmatory factor analysis to validate a 22-item instrument with 7 subscales: Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions, Hedonic Motivation, Price Value, and Habit.

Results

The dimensionality tests showed that the bifactor confirmatory model presented the best fit indexes: χ2173=434.86 (P<.001), χ2/df=2.51, comparative fit index=.97, Tucker-Lewis index=.95, and root mean square error of approximation=.053 (90% CI .047-.059). The invariance tests of the eHealth acceptability factor structure by sex demonstrated no significant differences between models, except for the strict model. The partial strict model demonstrated no difference from the strong model. Cronbach alphas ranged from .77 to .95 for the 7 factors. We measured the internal reliability with a 4-week interval. The intraclass correlation coefficients for each subscale ranged from .62 to .88, and there were no significant differences in the t tests from time 1 to time 2. Assessments for convergent validity demonstrated that the eHealth acceptability constructs were significantly and positively related to behavioral intention, usage, and constructs from the technology acceptance model and the theory of planned behavior.

Conclusions

The 22-item French-language eHealth acceptability scale, divided into 7 subscales, showed good psychometric qualities. This scale is thus a valid and reliable tool to assess the acceptability of eHealth technology in French-speaking samples and offers promising avenues in research, clinical practice, and marketing.
Age-Associated Capacity to Progress When Playing Cognitive Mobile Games: Ecological Retrospective Observational Study
Authors: Bonnechère Bruno , Bier Jean-Christophe , Van Hove Olivier , Sheldon Sally , Samadoulougou Sékou , Kirakoya-Samadoulougou Fati , Klass Malgorzata
Published: April 2020

Background

The decline of cognitive function is an important issue related to aging. Over the last few years, numerous mobile apps have been developed to challenge the brain with cognitive exercises; however, little is currently known about how age influences capacity for performance improvement when playing cognitive mobile games.

Objective

The objective of this study was to analyze the score data of cognitive mobile games over a period of 100 gaming sessions to determine age-related learning ability for new cognitive tasks by measuring the level of score improvement achieved by participants of different ages.

Methods

Scores from 9000 individuals of different ages for 7 cognitive mobile games over 100 gaming sessions were analyzed. Scores from the first session were compared between age groups using one-way analysis of variance. Mixed models were subsequently used to investigate the progression of scores over 100 sessions.

Results

Statistically significant differences were found between age groups for the initial scores of 6 of the 7 games (linear trend, P<.001). Cognitive mobile game scores increased for all participants (P<.001) suggesting that all participants were able to improve their performance. The rate of improvement was, however, strongly influenced by the age of the participant with slower progression for older participants (P<.001).

Conclusions

This study provides evidence to support two interesting insights—cognitive mobile game scores appear to be sensitive to the changes in cognitive ability that occur with advancing age; therefore, these games could be a convenient way to monitor cognitive function over long-term follow-up, and users who train with the cognitive mobile games improve regardless of age.
Quality of Information Regarding Repair Restorations on Dentist Websites: Systematic Search and Analysis
Authors: Kanzow Philipp , Büttcher Amelie Friederike , Wiegand Annette , Schwendicke Falk
Published: April 2020

Background

Repairing instead of replacing partially defective dental restorations represents a minimally invasive treatment concept, and repairs are associated with advantages over complete restoration replacement. To participate in the shared decision-making process when facing partially defective restorations, patients need to be aware of the indications, limitations, and advantages or disadvantages of repairs. Patients are increasingly using the internet to gain health information like this online.

Objective

We aimed to assess the quality of German-speaking dentist websites on repairs of partially defective restorations.

Methods

Three electronic search engines were used to identify German-speaking websites of dental practices mentioning repairs. Regarding information on repairs, websites were assessed for (1) technical and functional aspects, (2) comprehensiveness of information, and (3) generic quality and risk of bias. Domains 1 and 3 were scored using validated tools (LIDA and DISCERN). Comprehensiveness was assessed using a criterion checklist related to evidence, advantages and disadvantages, restorations and defects suitable for repairs, and information regarding technical implementation. Generalized linear modeling was used to assess the impact of practice-specific parameters (practice location, practice setting, dental society membership, and year of examination or license to practice dentistry) on the quality of information. An overall quality score was calculated by averaging the quality scores of all three domains and used as primary outcome parameter. Quality scores of all three domains were also assessed individually and used as secondary outcomes.

Results

Fifty websites were included. The median score of quality of information was 23.2% (interquartile range [IQR] 21.7%-26.2%). Technical and functional aspects (55.2% [IQR 51.7%-58.6%]) showed significantly higher quality than comprehensiveness of information (8.3% [IQR 8.3%-16.7%]) and generic quality and risk of bias (3.6% [IQR 0.0%-7.1%]; P<.001/Wilcoxon). Quality scores were not related to practice-specific parameters (P>.05/generalized linear modeling).

Conclusions

The quality of German-speaking dentist websites on repairs was limited. Despite sufficient technical and functional quality, the provided information was neither comprehensive nor trustworthy. There is great need to improve the quality of information to fully and reliably inform patients, thereby allowing shared decision making.

Authors: Punatar Shil U. , Khan Basharath A. , Charnetski Matthew , Rajnarayanan Rajendram
Published: April 2020

UNSTRUCTURED

Intro and Objective: In the presence of COVID-19, telemedicine is being utilized to limit person-to-person spread while increasing healthcare access. While telemedicine use is increasing, a mismatch exists with the amount of training to deliver care. For this, the American Medical Association has called for an increase in formalized training for telemedicine. This literature review provides recent examples of telemedicine education techniques to provide guidance for telemedicine training in this time of immediate need.

Methods: The authors conducted a literature review by searching the PubMed (MEDLINE) database for publications pertaining to telemedicine education and training. After review, 12 pieces of literature were analyzed for methods and skills taught in telemedicine, means to assess competency, and future directions.

Results: This study identified a broad scope of skills to be taught from orientation to technology, to patient interaction methods, as well as the current medico-legal guidelines. Using standardized assessments and being supervised by trained physicians, there is a role of telemedicine incorporation into formal curricula. As the field of telemedicine continues to adapt, so should the mechanisms by which training is delivered.

Conclusions/Discussion: While accepted that telemedicine provides access to care, especially in the time of COVID-19, this is not synonymous with quality of care if telemedicine training is lacking. The results of this work provide many current examples of telemedicine teaching to be incorporated across all healthcare disciplines. With this, we emphasize the need for growth in the area of telemedicine education and published data in the field.

AbstractThe Republic of Indonesia has ratified the United Nations Convention on the Law of the Sea 1982 (UNCLOS 82) through the Indonesian Law No. 17 of 1985 dated 13 December 1985, which was in force on 16 November 1994. As a result, Indonesia has established three archipelagic sea lanes, or otherwise known as ALKI (North-South), namely ALKI I, ALKI II and ALKI III. ALKI III has a three-pronged Southern points IIIA, IIIB and IIIC. With this establishment, Indonesia as the archipelagic state must be capable of ensuring safe passage of shipping through these lanes, while at the same time capable of enforcing its sovereignty over the related waters. The purpose of this study is to analyze the various determinant factors which affects the Indonesian Navy’s Second Fleet Command’s success in implementing sea control strategy within ALKI II which falls into its area of operations. These factors are tactics and procedures, weaponry capability, sensors capability, exercise and operational effectiveness. The research was conducted using mixed research methods. The determinant factor will be established in a statistic model which named Structural Equation Modeling which uses the Linear Structural Relationship (Lisrel) software version 8,70.  Qualitative analysis was conducted using the Soft System Methodology (SSM). The end results of this research concluded that all of the determinant factors would affect the Second Fleet Command’s ability to implement and execute the sea control strategy successfully. AbstrakIndonesia telah meratifikasi United Nation Convention on The Law of The Sea 1982 (UNCLOS 1982) melalui Undang-undang Nomor 17 Tahun 1985 tanggal 13 Desember 1985 dan mulai berlaku pada tanggal 16 November 1994.

KNOWLEDGE TRANSFER, INNOVATION AND SOCIAL NETWORKS APPROACH
Authors: Đorić Žarko
Published: April 2020

Modern society is dealing with a multitude of data, with predictions that by 2025 the produced data will amount to 160 zettabytes. A generation of useful information and derivation of knowledge from this data is becoming a laborious task, while transfer of relevant knowledge through social networks is becoming even more important. Although there are different definitions of social capital, there is a high level of compliance so that, unlike other concepts related to socio-economic development, social capital is unique because it is relational. It is obvious that the fundamental idea expressed in the concept of social capital is simple: social networks are important, they have value for people and organizations that are involved in this network. The aim of this paper is to analyze the role of social networks in the diffusion of knowledge and information and its contribution to the strengthening of innovative capacities. One of the main reasons for the growing interest in the role of social networks in the creation and transfer of knowledge is that most of the relevant knowledge today has an implicit character and cannot be easily transferred. The compilation method will be used in the paper for the purpose of reviewing existing theoretical and empirical research in this field. The method of description, as a procedure for simple description or reading of facts and processes, will be related to explanations of the notion of more important features of the described facts, their legality and causal connections and relationship.
LATENT STRUCTURE OF BELIEFS ABOUT MEN’S AND WOMEN’S EMOTIONAL BEHAVIOUR IN A SAMPLE OF SERBIAN STUDENTS
Authors: Pejičić Marija , Ćirović Nikola
Published: April 2020

Rules regarding emotional display (and hence, regulation) are provided by society in order to guide gender-specific or gender appropriate behaviour of the individual. The purpose of this research was the adaptation of the Questionnaire of gender specific beliefs about emotional behaviour (Timmers, Fischer, & Manstead, 2003), supplemented with additional items, on a sample of 247 Serbian students. A large set of observed beliefs about actual or desired emotional conduct in the context of separate male and female gender roles was subjected to sequential-factors analysis (Goldberg’s “bass-ackwards” method). The aim was to elucidate specific homogenous clusters of beliefs (factors) and their larger contexts (higher-level factors), therefore providing information on the societal views of gender roles and also on the potentially differing cross-cultural manifestations of the constructs in question. Finally, two measurement instruments were evaluated and suggested for future research. The psychometric properties of these instruments, the Beliefs about men’s emotional behaviour (BEB-M) and the Beliefs about women’s emotional behaviour (BEB-W), were assessed. Based on interpretability, as well as on the results of a parallel analysis and the MAP procedure, we made the decision to use a four-factor solution for the BEB-M instrument, and a five-factor solution for the BEB-W instrument.
EUROPEAN CULTURAL POLICY: PRIORITIES AND PRACTICES IN THE FIELD OF CULTURAL HERITAGE
Authors: Petković Jelena
Published: April 2020

By applying a comparative method and analysis of documents, this paper studies the altered position and role of culture as a delicate field of intervention in the field of European integration policies. From that standpoint we approach the socio-cultural and anthropological analysis of the basic directions of development in European policy in the fields of culture from the beginning of the process of EU integrations to this day. The aim of the research is to indicate the causes and consequences of increased interest of the European political agenda for the concept of cultural heritage, in particular from the 1970s, with the intention to critically analyze the conceptual interpretations and strategic uses of cultural heritage as part of European cultural policy. For that purpose, the paper provides insight into the basic research findings on the priorities and practices in the field of affirmation of the cultural heritage of Europe, obtained by analyzing and interpreting secondary sources (research papers, numerous internationally accepted documents, various European programs and projects). Conclusions are drawn on the unique contradictoriness in the rhetoric of European political actors, which in the field of cultural heritage balances between European particularism and universalism, as well as the unique strategic shift in European cultural activities from the primary affirmation of the symbolic and social potential of cultural heritage towards the increasingly emphasized use and abuse of its economic dimension.
SOCIAL MEDIA – “THE CLASSROOM” OF THE DIGITAL AGE
Authors: Vulić Tatjana
Published: April 2020

The goal of this research paper is to examine the frequency of use of social media by high school students in Serbia, as well as whether they use the social media to keep themselves informed and adopt informal knowledge, that is, to educate themselves. With regards to this topic, several research goals were set. The respondents were 155 students from “Prva kragujevačka gimnazija” (transl.: The First High School of Kragujevac) and “Prva tehnička škola” (transl.: The First Technical School) in Kragujevac, from 1st to 4th grade. The sample included 86 boys (55.5%) and 69 girls (44.5%). The questionnaire with 13 items was created specifically for this survey and it included the answer choices for the specific phenomena we investigated. Descriptive statistics was used during this research. Research findings suggest that high school students in Serbia spend more and more time on social media, primarily on Facebook (133 out of 155 respondents) which they also see as a source of information. Moreover, 49% of the respondents claimed that they trust this type of information and find it significant in peer-to-peer communication. Although more than a half of the respondents do not adopt role models and idols through social media, 45% of them still said that they have this tendency. Furthermore, this research has also shown that the largest number of respondents express their personal views on social media, two to three times a week.

Authors: Ćirić Marina , Pavićević Mirjana , Ćirić Nataša
Published: April 2020

Conflicts are present in every aspect of the child’s process of growing up– in school, family, with friends, and sports clubs. Nowadays, kids are often surrounded by peer violence which manifests in verbal, mental, and physical form. Attempts to solve such conflicts often result in making things even worse. The root cause of those issues is a different perspective on the problems at hand. The main goal of this research is to understand students’ perspective on conflicts they come across at school. We used descriptive statistics methods (frequency) and Х² tеst for measuring the significance of differences among crossed variable segments. Results of this research showed that the number of conflicts increases with age, meaning that there are more conflicts in higher grades. When it comes to solving these conflicts, students are prone to turning to teachers and professional associates at school, regardless of the fact that their parents show the desire to engage in solving peer conflicts.

Published: April 2020

The development of speech and language culture of pre-school children is one of important (if not the most important) tasks of preschool education. The paper contains the results of research on pronunciation of preschool children realized on a sample of 119 children of pre-school preparatory program. We have presented a standardized test of articulation. Research has highlighted the particular importance of early treatment of disorders in sound pronunciation of preschool children. Early identification of difficulties in pronunciation of children provides more adequate help and support from teachers, which help children with difficulties in articulating to get better achievements, not only in pre-school, but also later in school. This emphasizes the need for training teachers to determine the speech-language status of children, to use the articulation exercises of critical sounds in Serbian language sound system, and thus to correct the articulation disorders which do not belong to the etiology of speech pathology. For this purpose it is specially emphasized that children's literature is the basis for the realization of activities in the area of discrimination and articulation of sounds and speech in general, and in the later stages of the formation of children's vocabulary, logically connected and cultivated speech, expressive speech and a number of other targeted activities. Accordingly, in this paper we analyzed the role of the so-called "nonsense", "playful" children’s literature and practically presented papers that can be used in order to develop the speech of preschool children.

Authors: Jović Milica , Laković Mirjana , Jovčevski Marjan
Published: April 2020

Daily emissions of greenhouse gasses have a negative impact on the quality of the atmosphere. In almost every sector there is a certain emission of these gasses. This means that every sector, whether it is the energy, industry, transport sector or the household has a part in the degradation of the environment. In this connection, many models have been developed, whose task is to reduce greenhouse gas emissions and carbon dioxide as well to improve the environmental quality. This paper will discuss the carbon footprint model. A carbon footprint is the set of greenhouse gas emissions caused by something. It can be calculated for a product, service, person or even a country, and is used to understand the impact of human activity on the earth’s climate. Also, an analysis of carbon footprint using different types of fuel for heating households will be presented.
THE INFLUENCE OF AMBIENT CONDITIONS ON THE PERFORMANCE OF THE THERMOELECTRIC WIRELESS SENSOR NETWORK NODE
Authors: Milić Dejan , Prijić Aneta Predrag , Vračar Ljubomir , Prijić Zoran
Published: April 2020

This paper considers the effects of the ambient temperature and unducted air flow on the voltage generated by a thermoelectric generator used to power wireless sensor network node. Structure of the node is simulated using a fully coupled numerical electro--thermal model with convective correlations. Results show that the effect of the ambient temperature is negligible as long as the temperature difference between the hot surface of the node and the ambient is maintained. For natural convection, voltage dependence on the temperature difference can be determined from the open circuit conditions and this can be used to approximate the load conditions. For forced convection, an increase rate of the generated voltage is governed by the thermal resistance of the heatsink and characteristic parameters of the thermoelectric generator.
EMMISION OF POLLUTANTS ORIGINATING FROM MOBILE SOURCES ON THE EXAMPLE OF THE CITY OF KRAGUJEVAC
Authors: Marjanović Zoran , Raos Miomir , Jovanovic Milena , Randjelović Jovana
Published: April 2020

Traffic jam makes cities less pleasant for living and it also decreases traffic efficiency whereas travel time, fuel consumption and drivers’ stress are increased. A special problem is its influence on people’s health caused by emission of exhaust gases. Emission of pollutants originating from mobile sources is primarily conditioned by a level of technologies applied to the vehicle, vehicle’s technical state, traffic intensity, traffic density, local climate conditions, etc. Air pollution due to use of motor vehicles is becoming one of the major problems in urban areas across the world. With the increase of the number of motor vehicles and traffic intensification, the influence of exhaust gases on human environment also has increased. Considering the average age of the vehicles participating in traffic in the city of Kragujevac and the traffic capacity of traffic arteries, most frequently not designed for such a large number of vehicles concentrated at the core of the city, it is to be expected that the air pollution coming from mobile sources will become a problem that requires detailed analysis. For that purpose, a detailed statistical analysis of the vehicle fleet of the city of Kragujevac is conducted. An estimation of the influence of the vehicles on the air pollution in the city of Kragujevac, has been given in the paper.

THE ROLE OF STATE ADMINISTRATION AND LOCAL SELF-GOVERNMENT IN ENVIRONMENTAL PROTECTION
Authors: Ilić Mile , Ilić Petković Aleksandra
Published: April 2020

State administration and local self-government have numerous competences, which, according to the Constitution of the Republic of Serbia, have been elaborated through special laws. One of the specific competencies is the protection of the environment. There are many legal documents regulating this matter - from the Constitution to by-laws and acts at the level of local self-government units, so it can be said that the legal regulation in this area is extensive but not yet complete. In addition, the state administration, as a part of the state authority, plays a significant role in environmental protection policy, and local self-government authorities enable the implementation of this policy directly in immediate communication with citizens.
THE SELECTION OF A SMALL HYDRO POWER PLANT (SHPP) SOLUTION IN LINE WITH THE ECOSYSTEM
Authors: Stamenkovic Zivojin , Svrkota Dragan
Published: April 2020

Population growth and new forms of energy use have the effect that the energy demand grows year after year. The harmful influence of the use of fossil and nuclear fuels has influenced the intensive development of renewable energy sources (solar energy, small hydro power plants, wind energy, bio-renewable sources - biomass, geothermal energy). This paper gives an overview of the choice of design solution, technical parameters and the efficiency of small hydro power plants (SHPP) on small watercourses. Special attention in these considerations is dedicated to harmonization of selected solutions with natural resources and protection of ecosystems. In order to define the technical solution of one small HPP on a small watercourse, the following analyzes and studies need to be done: Hydrological study; Analysis of the available hydro potential; Pre-feasibility study of the chosen technical solution; Study on Environmental Impact Assessment; Analysis of the investment value of the elements of the system and the system as a whole; Analysis of annual fees and expenses. In analyzing the available hydro potential, it is necessary to examine in detail the influence of the minimum sustainable flow rate in the watercourse (biological minimum) both from the aspect of environmental protection and from the aspect of the techno-economic justification for SHPP construction. On the basis of the "cross-cutting" of the results of these analyzes, one can see the techno-economically justified solution for the construction of SHPP in line with the ecosystem. The goal of all previous analyzes is to select a technical solution that maximizes the use of hydro power potential and ensures optimum use of renewable energy sources, while paying special attention to ecology, environmental protection and sustainable development.

This study assessed the radioactivity levels and transfer factor of natural radionuclides around iron and steel smelting company located in Fashina village, Ile-Ife, Osun State, Nigeria. This was with a view to evaluate the exposure rate of the study area, determine the radionuclides present and activity concentration (238U and 232Th and 40K) in the samples and evaluate the soil-to-food transfer ratio of the radionuclides. A portable survey meter with a Global Positioning System (GPS) were used for in-situ investigation and a well-calibrated NaI(Tl) detector system was used for the radioactivity measurement of the samples. A total of 38 samples comprising soil, food and water were collected at the study area (Fashina) and control area (Opa) in Osun state, Nigeria for spectrometry analysis. The soil and food samples were oven dried, pulverized and sieved while water samples were acidified with 10 mL of 11 M HCl per litre to prevent adsorption of radionuclides with the wall of the container. All the samples were then sealed and kept for at least 28 days in radon impermeable cylindrical container so as to reach secular equilibrium. The mean exposure rates in the study area were 0.14 µSv hr-1 and 0.12 µSv hr-1 for the control environment. The mean radioactivity content obtained for 238U, 232Th and 40K were 12.14 ± 4.17 Bq kg-1, 23.23 ± 7.67 Bq kg-1 and 270.14 ± 61.79 Bq kg-1 respectively in soil samples and 8.56 ± 2.80 Bq kg-1, 13.17 ± 4.48 Bq kg-1 and 89.41 ± 24.15 Bq kg-1 respectively in food samples. Similarly it was 7.64 ± 2.95 Bq L-1, 10.04 ± 3.43 Bq L-1 and 69.04 ± 15.49 Bq L-1 respectively for 238U, 232Th and 40K in water samples. The transfer factor from soil to food for 238U, 232Th and 40K were calculated from the activity concentrations of soil and food, while the means were 0.73, 0.61, and 0.39 respectively in the study area.

En el presente trabajo presentamos los resultados de un estudio estratigráfico y paleontológico de nuevas localidades fosilíferas encontradas en el sustrato de las calderas La Reforma y El Aguajito, ubicadas aproximadamente a 30 km al norte de la población de Santa Rosalía, Baja California Sur, México. La sucesión sedimentaria estudiada se correlaciona con la Formación Tirabuzón del Plioceno de la cuenca de Santa Rosalía y forma parte del sustrato sedimentario de las calderas pleistocénicas. Una de las secciones más completas se encuentra expuesta en el cañón El Álamo y consiste en una sucesión de arenisca limosa de color naranja, conglomerado con abundantes fósiles de dientes de tiburón y rayas, un depósito volcánico basal y limolita de color amarillo ocre, las cuales en este trabajo se agruparon en tres unidades: 1) arenisca-limolita naranja, 2) depósito volcánico basal y 3) limolita Cimarrón. El material fósil estudiado consiste en 500 ejemplares de dientes individuales de elasmobranquios (macrodientes) que se extrajeron in situ. Para la localidad de El Álamo reportamos 19 taxa de tiburones y siete de rayas, siendo así el primer reporte de una fauna de Batoideos para la Formación Tirabuzón. La misma sucesión litológica y fósil fue encontrada en otras cinco localidades: Corkscrew Hill, Santa María, Cueva Amarilla, El Morro Prieto y El Gringo, en donde reportamos la presencia de Hemipristis Serra, así como Otodus megalodon y Parotodus benedeni para la localidad de Corkscrew Hill. Sobreyaciendo discordantemente a la unidad limolita Cimarrón se encuentra la ignimbrita Cueva Amarilla de la Formación Infierno fechada en 2.4 Ma. Estas nuevas localidades son una herramienta para poder correlacionar la Formación Tirabuzón hasta la porción noroccidental de la Caldera El Aguajito. El ensamblaje faunístico reportado corresponde a un ambiente marino somero de plataforma continental de aguas tropicales de edad Plioceno medio-superior.

Este trabajo presenta una caracterización del enfoque de enseñanza seguido por los profesores de Química en el municipio de Soacha. Con el fin de identificar el enfoque de enseñanza seguido por el grupo de estudio del profesorado, se aplicó el Enfoque de Enfoque Docente, TAQ. El estudio también implicó la determinación de variables sociodemográficas tales como: género, tiempo de estudio, tipo de institución, clasificación de docentes y calificaciones académicas.

El análisis e interpretación de los resultados condujo a las siguientes conclusiones: una alta presencia del enfoque de cambio conceptual centrado en los estudiantes enfatizado en las maestras de undécimo grado; correlaciones significativas entre el enfoque de enseñanza y las variables sociodemográficas como comuna y edad. También se concluyó una notable alta correlación entre el enfoque de enseñanza, la formación académica y la clasificación de los profesores de química. Sin embargo, no se encontró correlación entre el enfoque de enseñanza y el tiempo de estudio.

Palabras clave: Enfoques de Enseñanza; Cuestionario de enfoques de enseñanza; enfoque en el cambio conceptual centrado en los estudiantes; enfoque en la transmisión de información centrado en el profesor; variables sociodemográficas.

Authors: Trinidad Velasco Rufino
Published: April 2020

Se realizó un estudio sobre las creencias acerca de la enseñanza que tienen profesores de química de bachillerato. De acuerdo con un enfoque fenomenográfico, se utilizaron un par de instrumentos de investigación que permitieron describir y categorizar las creencias encontradas, las cuales pudieron clasificarse como tradicionales, transicionales y actualizadas. Básicamente se encontró que los profesores que cuentan con posgrados en educación centran su enseñanza en el estudiante, mientras que los que únicamente tienen una formación disciplinar en química, centran su enseñanza en ellos mismos.

El inicio de la década de los 20 no fue normal. Nos sorprendió con una noticia grande, de interés para todos, de fuera de México y posteriormente también aquí. El año 2020 inició con la noticia de que en la ciudad de Wuhan en China, había un brote de neumonías virales que provocaba que la gente buscara atención médica y cuya evolución no era igual a las infecciones respiratorias agudas conocidas. Uno de los primeros médicos, el oftalmólogo Li Wenliang notó el alto número de pacientes con síntomas parecidos y en diciembre del 2019 comentó que la enfermedad podría ser causada por un virus nuevo. El 7 de febrero del 2020 el Dr. Wenliang había muerto por la constante exposición a tal virus. Diez días después siguieron las muertes de otros médicos, el Dr. Liu Zhiming y el Dr. Xu Depu quien fuera director del hospital médico de la ciudad Ezhou en Hubei, además de muchos pacientes. Desde entonces, y hasta el 24 de marzo hay casi 400,000 infecciones y cerca de 20,000 muertos en todo el mundo, sin que parezca que los contagios comiencen a disminuir.
Pero ¿qué es lo que ocurre cuando el virus infecta? ¿Por qué es importante saber si alguien está infectado? ¿En qué consiste la prueba clínica? ¿Qué tipo de vigilancia epidemiológica se lleva a cabo en México? En este artículo se contestamos estas preguntas.
