La ciencia no hace más que avanzar y llevarnos a sitios nuevos e inexplorados. Pero la ciencia no avanza sola, hay que empujarla; acompañarla; trabajar días, meses, años o incluso más, hasta conseguir lo que se busca. Porque es así como todo empieza: buscando algo. En algún momento, alguien se da cuenta de que tiene una necesidad concreta para la cual no existe solución; o simplemente se le ocurre una idea de algo nuevo que le gustaría que existiera. Esa primera chispa puede venir de cualquier fuente y en cualquier circunstancia. Muchas no pasarán de ese punto, del comentario entre amigos sobre lo útil que podría ser cierta aplicación; pero otras encontrarán en esa primera idea el nacimiento de una parte del futuro. Así empezará un proyecto de investigación, con una idea transformada con los días en un objetivo más definido. De esta manera empezaron todos los grandes y pequeños descubrimientos. Y este proyecto no será solo una idea; será una planificación, será un estudio de lo que existe ...

Published: August 2021

The impoundment of dams can significantly alter shorelines, hydrological
regime, sediment and nutrient cycle. With the completion of Chushandian
reservoir dam, land use types around the reservoir have been profoundly
affected by flooding. As yet, the characteristics of soil properties on
different land use types in new built reservoir have not been fully
elaborated. In this work, we investigated the variation of soil physical
and chemical properties at distance scale for different land use types
after short-term inundating. Soil physical properties, chemical
properties, soil particle structure were determined. This study reported
that short-term inundating had impacts on soil physical and chemical
properties of different land use types. Our results indicated that the
soil physical and chemical properties at 0 m site of each land use types
may be mainly affected by the nutrient status of overlying water. The
soil TN, TC of all land use types decreased gradually with the increase
of distance from river bank, among which the contents of TN and TC at W2
were significantly higher than those at other sites. Compared with
woodland, both abandoned cropland and grass land showed the phenomenon
of soil particle loss and nutrient leaching. The characteristics of low
NH4-N and high NO3-N were observed in the woodland after flooding, which
may be related to denitrification. The main influencing factor is soil
microbial activity at W20. The main influencing factor is soil nutrient
status At W2. And at abandoned cropland and grassland, the main
influencing factor is soil physical properties. The response of
different land use types to short-term flooding may be mainly related to
the degree of vegetation coverage. Abandoned cropland showed stronger
resilience, while grassland showed stronger tolerance. The present study
suggested that early and timing restoration will be an effective way to
repair the riparian habitat.

Authors: Savic Nikola , Mirkovic Andrea , Bogdanovic-Vasic Slobodanka
Published: August 2021

Introduction. Emergency or postcoital contraception is a method of
contraception that is used within 72 hours after unprotected intercourse. It
is very important that adolescents consider emergency contraception with
awareness. It is not a regular method of contraception. The aim of this
study was to examine the knowledge and attitudes of adolescents towards the
use of emergency contraception. Material and Methods. The research was a
cross-sectional study that used a specially designed questionnaire for
adolescents intended to assess their knowledge about emergency contraception
methods. The study included an intentional sample of 108 students attending
the Medical High School ?Dr. Misa Pantic? in Valjevo. Participation in the
study was voluntary and anonymous. Results. The largest number of students
was informed about the indications for emergency contraception (80%, c2 =
0.004); the respondents agreed that emergency contraception is not a regular
method of contraception and should be used in cases of sexual abuse (c2 =
0.019). Most of the respondents believe that they need additional education
(N = 95, c2 = 0.032) regarding emergency contraception methods. Conclusion.
The analysis of the results showed that the adolescents who participated in
the study need additional education about the methods of emergency
contraception. It is necessary to improve the strategies of health education
of adolescents on this topic.

Published: August 2021

Introduction. Obstetric cholestasis is the most common liver disease during
pregnancy, which is predominantly associated with fetal complications.
Material and Methods. This retrospective study included a total of 44
pregnant women with obstetric cholestasis who gave birth at the Clinic of
Obstetrics and Gynecology, Clinical Center of Vojvodina, Novi Sad, from
January 1, 2014 to December 31, 2018. Results. The average maternal age was
34 years. The mean gestational age at diagnosis of obstetric cholestasis was
31 weeks, and at the time of delivery 35 weeks of gestation. Abdominal
pruritus was the main symptom of the disease affecting 72.72% of patients.
The mean bile acid level in the blood at the time of diagnosis was 25.26
?mol/L. Twenty nine patients (65.90%) gave birth vaginally, while 15
(34.09%) underwent cesarean section. The main maternal complication was
postpartum hemorrhage. The average blood loss was 567 ml. There were no
maternal deaths or stillbirths. The average newborn birth weight was 2830 g.
Respiratory distress syndrome was diagnosed in 8 newborns (15.09%). The mean
Apgar score at 1minute was 7, while at 5 minutes it was 9. Conclusion.
Individual approach, continuous clinical and laboratory monitoring with
adequate therapeutic treatment are necessary in patients with obstetric
cholestasis.

Authors: Djozic Isidora , Stokic Edita , Nikolic Jelena
Published: August 2021

Introduction. In recent decades, obesity has taken on epidemic proportions
and is becoming one of the most significant public health problems today.
The results of clinical and epidemiological studies show that obese pregnant
women can be considered a high risk group, given the increased risk of
maternal and fetal complications. The aim of this study was to examine the
relationship between pregnant women?s nutritional status and the development
of arterial hypertension, gestational diabetes and obstetric cholestasis
during pregnancy, as well as the impact of pregnant women?s nutritional
status on newborn birth weight and vital parameters at birth, assessed by
Apgar score. Material and Methods. This retrospective study included 71
pregnant women who were divided into two groups, depending on the
nutritional status. The first group included 28 pregnant women with a body
mass index < 25 kg/m? or less, whereas the second group included obese
pregnant women with a body mass index > 30 kg/m? or more. Birth protocol
data were used for the newborns. Results. In obese pregnant women, the
termination of pregnancy by cesarean section was statistically significant
more frequent (p < 0.05). Newborns of obese mothers had a statistically
lower Apgar score at 5 minutes, while higher body weight of newborns and a
lower Apgar score at 1 minute were at the limit of statistical significance
(p = 0.068). Arterial hypertension was more common in obese pregnant women
(p = 0.014), while gestational diabetes (p = 0.42) and obstetric cholestasis
(p = 0.51) were more common in obese pregnant women, but without statistical
significance. Conclusion. Obesity in pregnancy is a risk factor for the
development of hypertension, a higher incidence of cesarean section, and a
lower Apgar score of newborns.
Association between infant and young child feeding patterns and speech and language disorders
Authors: Milankov Vesela , Ognjenovic Nada , Veselinovic Mila , Velickovic Vanja
Published: August 2021

Introduction. Feeding patterns include manners in which a child is fed during
infancy and early childhood in order to provide him with appropriate
nutrients that will enable his proper growth and development. The purpose of
the present study was to determine the association between the dominant
feeding patterns in early childhood and the manifestation of speech and
language disorders in children aged 3 to 6 years. Material and Methods. A
crosssectional study was conducted during 2020 - 2021 and it included 100
children of typical development, aged 3 to 6 years. The research used the
Child Development Inventory, as a developmental screening instrument. The
questionnaire on feeding patterns was designed for the purpose of this
research. For data entry and processing, the Statistical Package for the
Social Sciences 20.0 software was used. Results. There were no significant
differences between the age categories of children in terms of deviations in
the development of expressive and receptive speech. Most of the examined
children (55%) were bottle-fed, whereas the remaining 45% were breastfed. A
significantly higher percentage of bottle-fed children showed a deviation in
the development of expressive and receptive speech compared to children who
were breastfed for at least the first 6 months (74.5% versus 8.9%).
Conclusion. Bottle-fed children showed a greater number of deviations in the
development of both expressive and receptive speech, compared to breastfed
children. Deviations in speech and language development were registered at
each examined age, which means that speech and language disorders are not
detected and treated in a timely manner.
Ultrasonographic findings of epididymal torsion in adults - a rare cause of acute scrotum
Authors: Donat Daniela , Torbica Slobodan , Trivunic-Dajko Sandra , Till Viktor
Published: August 2021

Introduction. Epididymal torsion is a rare cause of acute scrotum. Only a few
cases have been described in the literature, and preoperative ultrasound
diagnosis was done only in two cases. So far, according to our data, cases
of epididymal torsion in adults have not previously been reported in the
literature. Case Report. We report the case of a 39-year-old man, who was
admitted to the hospital for pain in the left hemiscrotum lasting for three
days. The physical examination revealed a swelling limited to the left
hemiscrotum, so the patient was referred for an ultrasound examination with
the diagnosis of epididymitis. The ultrasonography showed that the left
epididymis was significantly enlarged in the head area with and
heterogeneous structure of the parenchyma on a grayscale, without a
significant Color Doppler signal. At the level of the neck and the body of
the epididymis, there was a ?whirlpool sign? with a reactive hydrocele and
edema of the left scrotum soft tissue that was highly suspicious for torsion
of the epididymis. The patient underwent emergency surgery and epididymal
torsion of about 540 degrees was confirmed intraoperatively. Conclusion. The
torsion of the epididymis should be kept in mind in the differential
diagnosis of acute scrotal pain in adults.
Effects of positive end-expiratory pressure, carbon dioxide and body position on intracranial pressure measured by ultrasound assessment of optic nerve sheath diameter
Authors: Bojicic Adrijana , Jovanovic Gordana , Pajicic Filip , Tatic Milanka
Published: August 2021

Introduction. The optic nerve is surrounded by layers of meninges and
cerebrospinal fluid, which is why intracranial pressure affects the optic
nerve sheath. Noninvasive measurement of the optic nerve sheath diameter is
simple, accurate, repeatable and with minimal side effects. Effects of
positive end-expiratory pressure on intracranial pressure. The application
of positive end-expiratory pressure plays a significant role in improving
gas exchange, but it leads to an increase in intrathoracic and central
venous pressure, cerebral blood volume, reduces arterial and cerebral
perfusion pressure and thus futher increases intracranial pressure. The
effect of positive end-expiratory pressure depends on basal intracranial
pressure and respiratory system compliance. Effects of carbon dioxide on
intracranial pressure. Hypercapnia leads to cerebral vasodilatation and
increases cerebral blood flow and intracranial pressure. Hypocapnia reduces
intracranial pressure, but its prolonged effect may lead to cerebral
ischemia. Effects of body position on intracranial pressure. Body position
affects intracranial pressure, primarily by affecting cerebral venous
drainage. Conclusion. Body position, application of positive end-expiratory
pressure, and changes in carbon dioxide can affect intracranial pressure,
which is why its monitoring is of importance. Numerous studies show that
their effects on intracranial pressure can be easily monitored by ultrasound
assessment of optic nerve sheath diameter.

Video coding and constant quality evaluation using 4k aomenc-AV1 and rav1e-AV1 formats
Authors: Milivojevic Milan , Dujkovic Dragi , Gavrovska Ana
Published: August 2021

It is much expected from the relatively novel, open, royalty-free AV1
(Alliance for Open Media (AOMedia) Video 1) standard. At this moment, there
are many new variants of AV1 format. It is designed for efficient video
internet delivery and high-quality video transmission. AV1 is recognized as
Google?s VP9 format successor. One of the reference tools used so far for
testing AV1 is libaom- AV1. Nevertheless, due to its time-consuming
performance, there are now different available standalone solutions for
experimental analysis. Here, one such solution AOMedia?s standalone aomenc
(aomenc-AV1) is tested in order to analyze quality assessment based on
constant quality constraint factor. Three different metrics are calculated
for various 4k video content of the same frame rate. Moreover, rav1e
implementation was tested for the same visual data, where rav1e-AV1 also
represents an AV1 video encoder, which is considered reliable and suitable
in most cases, where libaom is not applicable. In this paper, the comparison
results between aomenc-AV1 and rav1e-AV1 are shown.
Modelling and optimising a new hybrid ad-hoc network cooperation strategy performance using genetic algorithm
Authors: Jumaa Noor , Allawy Abbas , Shubbar Mustafa
Published: August 2021

The lifetime of an ad-hoc network depends on a mobile device?s limited
battery capacity. In ad-hoc multi-hop communication, source nodes use
intermediate nodes as a relay to communicate with remote destinations. As
cooperation between nodes is restrained by their battery resources, it might
not be in their best interests to always accept relay requests. Therefore,
if all nodes decide how much energy to spend for relaying, selfish or
non-cooperative nodes reduce cooperation by rejecting to forward packets to
others, thereby leading to a dramatic drop in the network?s throughput.
Three strategies have been founded to solve this problem: tit-for-tat,
live-and-let-live, and selective drop. This research explored a new strategy
in ad-hoc cooperation which resulted from the combination of the
live-and-let-live and selective drop strategies. This new strategy is based
on the suggestion to select fewer hops with a low drop percentage and
sufficient power to stay alive after forwarding the data packets towards the
destination or other relays at the route path. We used a genetic algorithm
(GA) to optimise the cooperative problem. Moreover, the fitness equation of
the GA population was designed according to the mixing of the two
strategies, which resulted in a new optimized hybrid dynamic-static
cooperation.

Authors: Jiménez Sánchez Doniel , Arzola Ruiz José
Published: August 2021

Las mejores opciones de destino de hornadas de los semiproductos para la producción terminada de los talleres de la industria siderúrgica son aquellas en las que se minimiza el exceso de propiedades mecánicas con respecto a sus valores normados y se aseguran, por tanto, los valores requeridos de éstas. En este proceso se hace necesaria la estimación de las propiedades mecánicas de las hornadas a partir de su composición química y superficie transversal del producto terminado. En este trabajo la estimación se hizo mediante las redes neuronales de base radial regularizada, a partir de los datos acumulados de ensayos mecánicos en los talleres adoptados como caso de estudio. La utilización de estas redes permite disminuir los errores en la estimación de las propiedades mecánicas de los perfiles ligeros de acero. Se obtienen resultados satisfactorios en la generación de opciones de destino en un caso de estudio.
Bloody Disgusting! Abjection, Excess & Absurdity: The Carnivalesque Cohesion Between Horror & Comedy in Film & Television
Authors:   , Crowther Sarah
Published: August 2021

Horror and comedy. Screaming and laughing. Two genres and the visceral responses which they provoke, broadly considered to be polarised, apparently juxtaposed. This thesis argues that horror and comedy can be significantly more cohesive in their thematic traits, visual presentation and narrative events, than might initially be considered. Expanding a relatively underexplored academic field and building on the work of Paul (1994), the doctorate explores gross-out cinema and television in both theory and praxis. Part One opens with scholarly exploration of core theories of genre, horror and comedy. Semiotic and historical analysis and close reading of key texts in the horror, comedy, and hybrid horror comedy genre identifies and considers shared representation across the genres. Analysed texts include The Evil Dead series (1981-1992), Grimsby (2016), Nighty Night (2004-2005) and Braindead (1992). The core shared themes and representations across the genres are posited as abjection, excess and absurdity. Each of these elements is then explored in context of the tension of horror and humour co-present in the grotesque (Thomson, 1972). The paradoxical pleasure in reception (often in the disgust response) is found to align to the transgressions of the carnivalesque, and moreover, the carnivalesque grotesque (Danow, 1995, Bakhtin, 1974 et al.). These findings are then uniquely applied in praxis in Part Two in the original feature length film script Knitters! in which the women of the Potter’s Bluff Townswomen’s Guild must face an indestructible supernatural foe in an isolated Lake District resort. In the Lake District no-one can hear you scream! The Part Three exegesis reflects rigorously on the application of thesis findings in praxis, alongside detailed gnosis of the practical construction of a feature length script including close consideration of plotting, narrative pacing and characterisation.

El presente trabajo tiene el objetivo de reflexionar sobre el papel de los especialistas del campo del currículo en México (desde sus inicios en la década de los 70 hasta la actualidad) a partir de la perspectiva de quienes que se consideran como tales y de quienes han vivido el desarrollo de la disciplina. El método de estudio para este trabajo fue cualitativo, inductivo y exploratorio. La técnica de indagación fue la entrevista en profundidad, la cual se aplicó a cuatro especialistas curriculares para obtener datos sobre el significado de su actividad. El proceso de análisis se dividió en tres fases: reducción de datos cualitativos, análisis descriptivo e interpretación. Las perspectivas señalan que el campo del currículo necesita de nuevos investigadores que se consoliden como autoridades dentro de la disciplina, pues no se puede entrever un relevo generacional. En términos generales, los resultados confirman que pocos investigadores se pueden circunscribir dentro de la categoría de especialista en currículo.
Social cultural environment and public administration management based on the change of main social contradictions
Authors:   Heilongjiang Bayi Agricultural University, DaQing Heilongjiang, 163319, China, Li Xiao
Published: August 2021

The main contents of the ethical norms of public administration are the supremacy of public welfare, harmful inaction, and careful use of power, social responsibility, equal competition and enhancement of trust. Contradiction is a philosophical category reflecting the unity of opposites within and between things, and is the core content of materialist dialectics. The main social contradiction is the one that occupies the core position and dominates the society. Administration itself is not the ultimate goal, it is a series of communication channels to convey people's needs and wishes, and to ensure that these needs and wishes can be reflected and considered through state control. Similarly, these channels also play the role of the government in conveying policies and implementing tasks to the people. Therefore, if these channels are to make positive and significant contributions to people-centered development, the role of administration must adapt to the social-cultural environment and tradition.

Often, the employers allocate funds for occupational safety on the residual principle without considering the real needs in creating safe working conditions for the employees. This is especially topical for the small and medium-sized enterprises, whose budget, as a rule, does not allow to allocate sufficient funds for occupational safety. The substantiation is given concerning the need to improve modern systems for assessing the state of working conditions by integrating the missing elements, which are part of similar systems, selected during the analysis of domestic and foreign studies. In the critical review of foreign publications in the field of assessing the state of working conditions, the tools developed over the past 15 years are considered. The lines of business are selected related to the improvement of system for assessing the state of working conditions at the small and medium-sized Russian enterprises. To determine the most optimal methods, an algorithm is proposed for selecting the tools to assess the state of working conditions based on determining the efficiency parameter corresponding to each tool. Modern Russian methods are assessed in a similar way. As a result of the study, two tools for assessing the state of working conditions that are most optimal for small and medium-sized enterprises are selected. The analysis showed that the first selected method allows to assess the state of the personnel working conditions, i.e., gives a subjective assessment. The second method serves for an objective study of the estimated parameters, as well as for assessing the level of occupational hazard. Combined use of both tools can become the basis for the formation of a methodology for a comprehensive assessment of the state of working conditions at the small and medium-sized enterprises.

Fiber cement finishing materials are widely used in the construction of industrial buildings and structures due to the complex of valuable operational properties. In the Russian market there are fiber-cement panels with a variety of design solutions for their coloring and application of protective coatings. Fiber cement board is a strong and moisture-resistant composite material made from a cement-sand mixture, reinforcing cellulose fibers and special additives. Not being a non-combustible material, the fiber cement boards in accordance with the current mandatory requirements, as a decorative, finishing and facing material for walls and ceilings have restrictions on their use. Existing domestic requirements regarding the methodology for assessing the combustibility of fiber cement products largely narrow the field of using these materials. Therefore, it is advisable to develop the proposals for amending the test methods and the regulatory framework governing their fire-safe extended scope. In the course of this work execution, the main provisions of the regulatory and methodological framework that establish the requirements for the fire-safe use of fiber cement materials are analyzed. Experimental complex studies of fire hazard properties of various types of samples of the fiber cement finishing panels and slabs were carried out. It is established that fiber-cement materials belong to the class of the least fire-hazardous materials. Advisability is determined concerning the introduction to the national regulatory practice of GOST R «Building materials. Test method for fire hazard under thermal exposure with a single burner (SBI)». Classification parameters of the group of non-combustible materials NG2 were established to amend GOST R 57270—2016 (method 1). Classification parameters of the group of non-combustible materials NG2 for making changes in GOST R 57270—2016 (method 1) are established. Proposals were developed to expand the scope of application of the materials and products made of fiber cement as enclosing structures, partitions, and decorative finishes (cladding) in the buildings and structures.
Design-Basis Justification for the Application of Large Diameter Hose Complexes in the Hydraulic Submersible Pump Systems during Emergency Management

Pumping and hose complexes are one of the most efficient technical means used for supplying large volumes of water (up to 200 l/s or more) or drainage over significant (hundreds of meters) distances. Transportation of water and other technical fluids is carried out by hoses of large (over 150 mm) diameters. Operational experience showed that the use of hoses with a diameter of over 250 mm causes small losses of water pressure during transportation along the hoses, but negatively affects the operational and tactical capabilities of the complexes. Due to the large mass of the transported hoses and the significant load on the chassis, the off-road passability of the complexes is reduced; deploying a hose line in a complex natural and urban landscape and cleaning it after an emergency is time-consuming with the involvement of the great number of the uniformed force. The problem of creating new generation pumping and hose complexes required optimization of the diameter of the pressure hoses for ensuring transportation of the maximum possible amount of water over the required distances without critical pressure losses. The performed calculations show that the optimal pressure hose diameter is 225 mm considering technical characteristics of the applied pumping units. Using them it is possible to deploy the hose line at distances from 450 to 1000 m and more depending on the amount of the transported fluid and its pressure at the end of the hose line. Due to the lower mass of the linear meter of the hose and connecting heads, the load on the chassis and on the device for mechanical unfolding and cleaning of the hoses is reduced by more than 29 %, the reliability of chassis units and assemblies and the superstructure of the pumping and hose complexes increases. Correctness of the performed calculations is confirmed by their practical application at the development of the work execution plan on pumping a water-diesel mixture from the emergency zone in the Norilsk region.

The issues are considered related to providing mining enterprises with the engineering personnel capable of managing mining and blasting operations. At present, not all the mining enterprises have a full staff of specialists and managers who are legally entitled to manage mining and blasting operations. Some employees who previously had such a right, after changes in the legal framework, ceased to meet the new requirements. The analysis is presented concerning the competencies required to perform these production functions, as well as educational programs that allow acquiring these competencies. The importance of professional retraining programs for solving these problems and the imperfection of the modern regulatory framework, which practically excludes the possibility of obtaining the right to manage mining and blasting operations, even after professional retraining for persons with a higher technical education in a non-mining profile, are shown in the article. An integrated approach is proposed for resolving the issues of the admissibility of obtaining the right to manage mining and blasting operations by these persons considering a number of factors: basic education, work experience and positions held at a mining enterprise, completed training in programs of additional education and professional retraining. Such programs should be developed and implemented by the organizations with experience in training mining engineers and having a license from Rosobrnadzor for the right to implement programs not only for additional professional education, but also for higher professional mining education. The need is substantiated in developing professional standards for managers of mining and blasting operations at the enterprises for the extraction of solid minerals. Recommendations were developed for amending the federal rules and regulations in the field of industrial safety in order to ensure the possibility of using professional retraining programs for training and final certification of the managers of mining and blasting operations.

Liver mineral concentrations of 232 samples from slaughtered animals, including  lamb, yearling, sheep, and cattle, checkin, and fish were detrmined, using X-ray fluorescence spectrometer, to provide data regarding to the liver mineral concentrations (mg/kg dry weight). The mean liver Zn and Co liver conentrations of lambs (286, 1.9), yearling (233, 1.7), sheep (254, 1.8), and cattle (276, 1.8) in majority samples were adequate, while liver Pb concentrations of mentioned animals (45.3, 48.1, 46.4, 39.6) mg/kg respectively were high and exceeded toxic levels. In checkin, the mean liver Cu, Zn, and Co were also adequate, with the mean values of (26.4), (298.8), and (1.8) mg/kg respectively. Though, the mean liver Fe concentration (2257.0 mg/kg) was high, and liver Pb concentration (6.2 mg/kg) was reched toxic level. In fish, for majority liver samples, the mean concentration of Cu (191.8), Fe (6800.0), Zn (202.8), Co (3.3), Pb (8.6), and Ni (6.3) were high and toxic. In conclusion, liver Pb (and Ni only in fish) concentration in all studied animals for the majority of examined sample were higher than normal and toxic. Wherese, other studied minerals in majority of liver samples were adequate. Therefore, it can be concluded that there are problems on animal and human health (due to high concentration of Pb and Ni) would be raised at present from the consumption of ovine, bovine, checkin, and fish slaughtered from the city of Erbil.

Authors: Condori Gutiérrez Juan Luis
Published: August 2021

El artículo se propone describir las competencias socioemocionales que se perfilan en los directivos, enmarcadas desde un enfoque del liderazgo positivo, que es una perspectiva orientada hacia el aprendizaje continuo y que influye de manera directa en el equilibrio de las relaciones entre los miembros de la comunidad educativa. Los directivos que resuelven situaciones en las cuales se involucran los estados emocionales tanto de docentes, estudiantes y padres de familia, impactan de manera favorable, influyendo en la mejora del clima organizacional, aumentando la calidad de las relaciones entre los miembros de la institución educativa. El desarrollo temático del artículo se inicia con las aproximaciones conceptuales sobre competencias socioemocionales y clima organizacional. Luego, se presentan dos propuestas de organización de las competencias socioemocionales del directivo; la primera toma como punto de partida el Marco de Buen Desempeño del Directivo, documento elaborado por el Ministerio de Educación, en el cual se identifica la competencia y los desempeños relacionados con rasgos socioemocionales. La segunda propuesta, es de carácter sintético y se orienta a las dimensiones intrapersonales e interpersonales, con resultados para la toma de decisiones. Finalmente, se realiza la reflexión de ambas propuestas, orientando sus avances en la realidad de las instituciones educativas, así como su relevancia en el desarrollo del clima organizacional y su relación con el liderazgo educativo.
