Introducción: La salud mental, además de ser un fenómeno complejo y multifactorial, ha aumentado a la par del incremento de la densidad poblacional, observándose cada vez más en población adolescente y en adultos jóvenes. Dentro de los factores que favorecen la prevalencia o la desencadenan están el estrés y el ambiente donde se desenvuelve el individuo. La residencia médica es considerada un reto cada vez mayor para nuestra población de médicos residentes y un desencadenante de situaciones de estrés y por ende favorecer la ansiedad.Objetivo: Identificar la relación entre el tipo de personalidad con el nivel de ansiedad en residentes de las especialidades en medicina familiar (MF) y en traumatología y ortopedia (TyO).Método: Se lleva un estudio observacional en médicos residentes de las especialidades de traumatología y ortopedia y de medicina familiar. Se les aplica el test 16PF5 para valorar las cinco dimensiones de la personalidad y el test de ansiedad de Hamilton.Resultados: Se obtuvo una muestra de 116 residentes. Presentaron ansiedad leve 29.4% de MF, mientras que TyO fue observado en el 70.5%. Ansiedad moderada/grave lo presentaron el 60.7% de MF, y el 39.2% de TyO. En cuanto al análisis de las cinco dimensiones globales de la personalidad (test 16PF5), la extraversión los resultados se concentraron en el polo negativo. En la dimensión ansiedad, los resultados fueron diferentes para ambas especialidades. En la dimensión de dureza se concentra la mayoría en el extremo negativo. En las dimensiones de autocontrol y de individualidad se encontró resultados similares entre ambas especialidades.Conclusiones: Hay ciertas similitudes en el tipo de personalidad en ambas especialidades, pero con claras diferencias en el nivel de ansiedad con tendencia a algún tipo de ansiedad en residentes de TyO, mientras que la mayoría de residentes de MF no presenta ansiedad.

Glowing Plants Can Light Up the Night Sky? A Review
Authors: Li Bolong , Chen Ru , Zhu Chenba , Kong Fantao
Published: April 2021

Luminescence, a physical phenomenon that producing cool light in vivo,
has been found in bacteria, fungi and anminals but not yet in
terrestrial higher plants. Through genetic engineering, it is feasible
to introduce luminescence system into living plant cells as biomarkers.
Recently, some plants transformed with luminescent systems can glimmer
in darkness, which can be observed by our naked eyes and provide a novel
lighting resource. In this review, we summarized the development of
luminescence in plant cells, followed by exampling the successful cases
of glowing plants transformed with diverse luminescent systems. The
potential key factors to optimize a glowing plant are also discussed.
Our review is useful for the creation of the optimized glowing plants,
which can be used not only in scientific research, but also as promising
substitutes of artificial light sources in the future.
Four key challenges in the era of big data: Ecology must move beyond Noah's ark
Authors: Salguero-Gómez Roberto
Published: April 2021

Long-term, individual-level records are of great importance in
biological sciences. By understanding how individuals contribute to
their populations during representative temporal scales, we can answer
pressing questions in ecology, evolution, and conservation biology.
These questions include identifying which, how, and where species’
populations will go extinct or become invasive. Calls for the
collection, curation, and release of these kinds of ecological data have
contributed to the open data revolution in ecology. Birds, particularly,
have been the focus of much citizen science and international research
for decades, resulting in a number of uniquely longterm studies.
However, accessing some of these individual-based, long-term datasets
can be challenging. Culina et al. (2021) introduce an online repository
of individual level, long-term bird records with ancillary data (e.g.
genetics). Similar efforts have also been undertaken for mammals, fish,
and even more recently for corals and insects. By releasing these
ecological data open-access, the research community is starting to fill
“Noah’s ecological ark”. However, important challenges still lay ahead
to address the most pressing research questions. Here, I briefly
overview the open access landscape of long-term animal ecological
studies, provide suggestions for how to most efficiently expedite our
knowledge of long-term animal population dynamics, and highlight four
key challenges in the use (and misuse) of these large volumes of animal
ecological data.
La valoración docente como mecanismo de mejoramiento del proceso de enseñanza-aprendizaje en la carrera de Administración de Empresas
Authors: Morales Gamarra Said Rodrigo
Published: April 2021

La importancia de la tasación del desempeño docente en el proceso de formación, que permite describir las características desde una perspectiva del proceso enseñanza-aprendizaje, ya que la problemática hace mención de que no se conocen de manera objetiva y pertinente los aspectos inherentes a la labor formativa, lo que limita a la retroalimentación oportuna de la mejora continua en el proceso formativo. Es por esta razón por lo que se transversaliza la función formativa desde un enfoque integral docente-estudiante centrado en el problema de cómo evaluar el proceso de enseñanza universitaria, que pueda sustentar el perfeccionamiento del desempeño docente. El estudio tiene como objetivo describir la tasación docente dentro de la carrera de Administración perteneciente a la facultad de Ciencias Económicas y Financieras de la UAJMS, ubicada en la provincia Cercado del estado plurinacional de Bolivia.
El tipo de investigación utilizada fue descriptiva y se estudiaron los aspectos inherentes al proceso de formación. Se trabajó con 460 estudiantes como referencia poblacional y 20 estudiantes como muestra aleatoria, a los que se les realizó un cuestionario con énfasis en los componentes del proceso de enseñanza. Luego se presentaron los resultados primarios, que permitieron llevar a cabo la discusión de los componentes observados en el estudio, como ser la organización y planificación de la labor formativa, la utilización de recursos tecnológicos y la formación integral de los futuros profesionales. Finalmente, se presentaron las conclusiones más relevantes del estudio, en las cuales se puede mencionar que la planificación y la organización de la cátedra en las diferentes asignaturas se realizó con base en el programa docente presentado. Se aplicaron sistemas de evaluación clásicos, que carecen de aspectos de retroalimentación, lo que limitó las instrucciones académicas respectivas, para lo cual también se utilizaron datos de estudios previos, que son parte de una investigación complementaria.

A system for impro­ving control of at­ten­ti­on of transport me­ans dri­vers has be­en de­ve­lo­ped. An analysis of li­te­rary so­ur­ces on the exis­ting met­hods and systems instal­led on mo­dern cars for es­ti­ma­ting dri­ver's ti­red­ness has be­en con­duc­ted. No­wa­days the­re are se­ve­ral ways to ob­ta­in da­ta abo­ut dri­ver's ti­red­ness. The da­ta are ba­sed on the dri­ver's physi­olo­gi­cal sta­te at the whe­el analyzing his physi­olo­gi­cal re­ac­ti­on. On the ba­sis of the con­duc­ted analysis the ad­van­ta­ges and di­sad­van­ta­ges of the exis­ting system ha­ve be­en re­ve­aled. An al­go­rithm of the system's functi­oning and a struc­tu­re for fo­cu­sing at­ten­ti­on of dri­vers of transport me­ans ha­ve be­en de­ve­lo­ped and a lo­gic mo­del has be­en bu­ilt. The system's struc­tu­re is ba­sed on mo­du­lar prin­cip­le which ma­kes it pos­sib­le to impro­ve and mo­der­ni­ze the de­sig­ned de­vi­ce. A struc­tu­ral mo­del of the system, de­ve­lo­ped on the ba­sis of Pet­ri net the­ory, ma­kes it pos­sib­le to re­se­arch dyna­mics of the system functi­oning on the system le­vel of de­sign.

Published: April 2021

The peculiarities of neural network training for forecasting taxi passenger demand using graphics processing units are considered, which allowed to speed up the training procedure for different sets of input data, hardware configurations, and its power. It has been found that taxi services are becoming more accessible to a wide range of people. The most important task for any transportation company and taxi driver is to minimize the waiting time for new orders and to minimize the distance from drivers to passengers on order receiving. Understanding and assessing the geographical passenger demand that depends on many factors is crucial to achieve this goal. This paper describes an example of neural network training for predicting taxi passenger demand. It shows the importance of a large input dataset for the accuracy of the neural network. Since the training of a neural network is a lengthy process, parallel training was used to speed up the training. The neural network for forecasting taxi passenger demand was trained using different hardware configurations, such as one CPU, one GPU, and two GPUs. The training times of one epoch were compared along with these configurations. The impact of different hardware configurations on training time was analyzed in this work. The network was trained using a dataset containing 4.5 million trips within one city. The results of this study show that the training with GPU accelerators doesn't necessarily improve the training time. The training time depends on many factors, such as input dataset size, splitting of the entire dataset into smaller subsets, as well as hardware and power characteristics.
METHODS OF BUILDING A MODEL OF USER BEHAVIOR

Published: April 2021

The number of clustering methods and algorithms were analysed and the peculiarities of their application were singled out. The main advantages of density based clustering methods are the ability to detect free-form clusters of different sizes and resistance to noise and emissions, and the disadvantages include high sensitivity to input parameters, poor class description and unsuitability for large data. The analysis showed that the main problem of all clustering algorithms is their scalability with increasing amount of processed data. The main problems of most of them are the difficulty of setting the optimal input parameters (for density, grid or model algorithms), identification of clusters of different shapes and densities (distribution algorithms, grid-based algorithms), fuzzy completion criteria (hierarchical, partition and model-based). Since the clustering procedure is only one of the stages of data processing of the system as a whole, the chosen algorithm should be easy to use and easy to configure the input parameters. Results of researches show that hierarchical clustering methods include a number of algorithms suitable for both small-scale data processing and large-scale data analysis, which is relevant in the field of social networks. Based on the data analysis, information was collected within fill a smart user profile. Much attention is paid to the study of associative rules, based on which an algorithm for extracting associative rules is proposed, which allows to find statistically significant rules and to look only for dependencies defined by a common set of input data, and has high computational complexity if there are many classification rules. An approach has been developed that focuses on creating and understanding models of user behaviour, predicting future behaviour using the created template. Methods of modelling pre-processing of data (clustering) are investigated and regularities of planning of meetings of friends on the basis of the analysis of daily movement of people and their friends are revealed. Methods of creating and understanding models of user behaviour were presented. The k-means algorithm was used to group users to determine how well each object lay in its own cluster. The concept of association rules was introduced; the method of search of dependences is developed. The accuracy of the model was evaluated.

Раскрывается процесс расширения профессионально-личностного развития студентов, обучающихся в магистратуре, что обеспечивает высокий уровень профессиональной продуктивности в будущем. На основе эмпирического исследования определены субъективные мотивы поступления и трудности, встречающиеся на пути магистрантов. Именно магистерская подготовка должна быть ориентирована не только на формирование готовности магистрантов технического вуза к профессиональной деятельности, но и на подготовку высококвалифицированного специалиста с развитыми личностными качествами. Оказалось, что успешное обучение требует продуктивных отношений и конструктивного общения между преподавателем и студентом. Преподаватель должен уделять больше внимания магистрантам, прибывшим из других направлений подготовки, организовывать для них дополнительные консультации как индивидуализированную форму приобретения знаний и опыта, а также конструктивно использовать часы, отведенные на самостоятельную работу, для организации сотрудничества со студентами.

In the work briefly deals with the concept of “professional development», which involves a professional choice, a line of career, features of professional behaviour at work, professional achievements, satisfaction from the process and results of labor, efficiency of educational behavior of personality change or stability of the workplace, the profession. The article reveals the process of expanding the professional and personal development of students studying for a master’s degree, which ensures a high level of professional productivity in the future. On the basis of empirical research, the subjective motives of admission and difficulties encountered on the way of undergraduates were determined. Therefore, master’s degree training should be focused not only on the formation of the readiness of undergraduates of a technical University for professional activity, but also on the training of a highly qualified specialist with developed personal qualities. As a result, it turned out that successful learning requires a productive relationship and constructive communication between the teacher and the student. For undergraduates, the teacher should pay more attention to undergraduates who come from other areas of training, organize additional consultations for them as an individualized form of acquiring knowledge and experience, and constructively use the hours allocated for independent work to organize cooperation with students.

Authors: Telli Sahure Gonca , Aydın Samet
Published: April 2021

Apart from the threat it poses for human health all over the world, Covid-19 pandemic has had a devastating effect on the economies of all countries due to the measures taken by governments to restrict human mobility and social life driven by the concerns that health systems would collapse. In this period, radical changes in business relations, working style, and consumer behaviors have forced businesses to seek different management strategies. Based on the idea that the changes that occur will leave permanent marks in many ways, it is expected that all functions of businesses will be digitalized due to the digital transformation required by the post-pandemic period defined as the "new normal". Business Administration departments and business education at universities play an important role in making students ready for this new era, and in making them become a part and even pioneers of this transformation after graduation. Accordingly, the curricula of the Business Departments where future manager candidates are trained should be revised and converted into new systems, in the process of adaptation to the digital society. Thus, the main purpose of this study is to determine the extent the courses are included for digitalization in the Business Administration departments' curricula which are traditionally a subdivision of the Faculty of Economics and Administrative Sciences. The curricula, and the core and elective courses of all Business Administration departments in Turkish universities that were active in 2020 were reviewed, and a descriptive research was conducted on the courses regarding their digitalization through the departmental websites. It was found out that although inclusion of digital transformation courses has begun in the Business Administration programs in Turkey, this inclusion has not been widespread. This study will contribute to the literature with the awareness it creates regarding the future of business education by taking into account the permanent effects of Covid-19.

University years can be perceived by a young adult as a complex time involving many changes. In this period, the individual encounters various problems that s/he needs to overcome. Since young people are not always able to solve their problems on their own in this critical period, they seek professional help. There are many individual and environmental variables that affect university students' attitudes of seeking professional psychological help. The present study investigated the relationships between university students' attitudes towards seeking professional psychological help, their attachment styles, and personality traits. The study group consisted of 786 university students, of whom 441 were female, 320 were male, and 25 declined to state gender. Demographic Information Form, Attitudes Towards Seeking Psychological Help Scale-S, Relationship Scales Questionnaire and Adjective-Based Personality Test were administered to the participants. The obtained data were analyzed by using the Pearson product moment correlation coefficient and multiple linear regression analysis techniques. The results of the analyses showed that the attitudes towards seeking professional psychological help positively and significantly correlated with the secure attachment style, while it significantly but negatively correlated with the preoccupied attachment style. The attitudes towards seeking professional psychological help also showed a significant correlation with the traits of extraversion, openness, good-temper, and responsibility.

To this end, a deep and comprehensive investigation was performed using the phenomenological approach, which is a qualitative method, with 36 academic staff who had experienced silence within the relevant formal structure. The findings revealed that silence in the context produced by structural and cultural characteristics of formal group settings of academic organizations was caused by psychological, socio-cultural, individual, situational, and managerial factors, and factors attributed to the organizational context, besides the system. On the other hand, the synthesis of textural and structural descriptions showed that silence reflects a form of political behavior in formal group settings of academic organizations. The study identified different definitions and insights related to the phenomenon of silence in organizational life.

De veghe în turpitudinea nedemnului. Prolegomene ale posibilei invocări
Authors:   Facultatea de Drept, Universitatea „Alexandru Ioan Cuza” din Iași, Macovei Codrin
Published: April 2021

This article examines a particular aspect of invoking succession unworthiness. Regarding the sphere of persons who would have active procedural capacity in an action to ascertain/stating the indignity, we include in this category: legal or testamentary co-heirs (whose inheritance rights would have been restricted by the coming of the unworthy to inherit); subsequent legal heirs (whom the presence of the unworthy would have removed from the inheritance); donees or legatees (whose liberalities could have been reduced if they had infringed the succession reserve quota of the unworthy); the creditors of the legal co-heirs, of the subsequent legal heirs, of the donees or legatees (the exercise of the oblique action is allowed, not being an exclusive personal right); the unworthy heir. However, there are some dilemmas regarding unworthy heir. Until we can discern a different regime of invocation depending on the type of indignity, legal or judicial, we must answer the fundamental question of its interest. Could the principle nemo auditur turpitudinem allegans be applied in this case? Before finding a definitive answer to this question, this article aims to determine the legal nature of this institution and its history.
Gheorghe Mârzescu și vocația libertății. Despre un profesor uitat al Facultății de Drept din Iași
Authors:   Facultatea de Drept, Universitatea „Alexandru Ioan Cuza” din Iași, Mâță Dan Constantin
Published: April 2021

Professor Gheorghe Mârzescu's contribution to the development of legal education at the University of Iași is essential. A French legal expert, he was actively involved in the institutional and didactic consolidation of the Faculty of Law in its first years of operation. The fact that for a long time he did not have the status of professor shows us the difficult context in which the foundations of the university education from Iasi were laid. Through his works Gheorghe Mârzescu is the founder of the scientific study on civil law at the University of Iași. He was a follower of liberal values and a constant promoter of the principle of laicization, which is why he openly came into conflict with the representatives of the Church. Despite this complexity, the life and work of Professor Gheorghe Mârzescu are less well known today, often being mistaken for his son, an important politician at the beginning of the interwar period. This article aims to bring back to life some of the complex valences of this personality, emphasizing its founding role and the vocation of freedom that he has permanently promoted.
Asupra existenței și utilității dreptului natural: evoluția unui concept
Authors:   Facultatea de Drept, Universitatea Babeș-Bolyai, Tomuleț Cristina
Published: April 2021

In this article, I approached the concept of natural law, starting with the analysis of some of its first definitions developed by Cicero. Moving toward recent history, I demonstrated the usefulness of this concept in the context of dealing with legal systems specific to dictatorial regimes. Next, I presented arguments proving the existence of natural law and I determined its content, referring to the general principles included in it, which underpin positive law, and to its importance in terms of ensuring respect for fundamental rights. In the final part of this article, I analyzed the confrontation between jusnaturalism and legal positivism in order to highlight even more clearly the features of natural law. Last but not least, I stressed the importance of choosing a jusnaturalistic legal mindset in order to prevent and fight against legal systems that are manifestly contrary to natural law.

EPR TESTING OF ORGANIC VERSUS CONVENTIONAL MUSACEAE FRUITS
Authors: PETRIŞOR D.M. , DAMIAN G. , SIMON S.
Published: April 2021

In the present study, the EPR spectroscopy was used to evidence differences in fruits of organically and conventionally grown bananas belonging to musaceae family. If in the investigated samples would be detected specific changes related to paramagnetic resonant centers, these could be regarded as a spectroscopic fingerprint in the differentiation of the organic and conventional fruits and vegetables. The EPR spectra were recorded from freeze-dried shell and pulp samples. The main paramagnetic species (iron, manganese and native semiquinone free radical) delivered for the investigated samples slight different EPR signals. In this stage, the results obtained by EPR testing put in evidence sensible differences between the two classes of samples, and draw the attention on differences in EPR signals recorded from banana pulp and shell.

El retrato político en la época de su reproductibilidad digital: análisis visual y mediológico de un caso
Authors: Luna Diego
Published: April 2021

La digitalización ha revolucionado la manera en que las imágenes son producidas y puestas en circulación. Los signos visuales son añadidos instantáneamente a la órbita de Internet, donde son alterados y reproducidos hasta la saciedad, perdiendo en muchas ocasiones su significado original y generando nuevas formas e interpretaciones indeseadas. Como muestra el análisis visual y mediológico de un célebre caso, la imagen del matrimonio Obama con Rodríguez Zapatero y familia en el Metropolitan Museum of Art de Nueva York, el género del retrato político no ha permanecido ni mucho menos ajeno a esta situación. El conflicto sociocultural derivado de la confluencia de diferentes regímenes representacionales dentro de aquella instantánea continúa alimentando hoy, diez años después de su aparición, la reflexión sobre las múltiples y estrechas conexiones existentes entre estética y política.
