Published: January 2021

Objective. The aim of this work was to obtain the primary cell lines of brain malignant tumors using the explant method.

Materials and methods. Thirteen patients of both sexes, aged 22 to 66, were recruited. The tumor material of the patients was fragmented and placed in flasks with complete nutrient medium for glial tumor cells. Subsequently, the material was photographed at various stages of cultivation, the cell morphology was determined, and the rate of monolayer formation at the zero and first passages was assessed.

Results. As a result, thirteen primary human cell lines of glial tumors were obtained: six glioblastoma lines, two glioblastoma lines with anaplastic astrocytoma, one anaplastic oligodendroglioma line, one diffuse astrocytoma line, one oligoastrocytoma line and one diffuse protoplasmic astrocytoma line, one anaplastic astrocytoma line. In the culture of diffuse astrocytoma, there were observed the cells forming a network at the bottom of the flask. In the culture of anaplastic astrocytoma at a confluence of 3050 %, fibroblast-like cells were presented, and at a confluence of 100 %, a monolayer was formed with cells intimately adjacent to each other. In the culture of oligoastrocytoma, both fibroblast-like cells and islets of closely intertwined fusiform cells were observed. The same was typical for the cells of diffuse protoplasmic astrocytoma. Anaplastic oligodendroglioma during the first week of cultivation was represented mainly by round cells with a contrast agent, which subsequently attached and actively proliferated. At a confluence of 3080 %, fibroblast-like cells were observed, and at 100 %, spindle-shaped cells closely adjacent to each other. In cultures of glioblastomas, no specific character of cell growth was revealed: spindle-shaped, fibroblast-like cells and cells with long processes forming a network were encountered. Glioblastoma cultures against the background of anaplastic astrocytoma were represented by a network of cells with long processes.

At the zero passage, the rate of formation of a 100 % confluence monolayer ranged from 22 to 85 days. At the first passage, the cells reached a full monolayer within 4 to 25 days. At the zero passage, the longest time among all the samples to form the monolayer with a 100 % confluence needed glioblastoma lines on average 59 days. The shortest time to reach a 100 % confluence was required for cells of diffuse astrocytoma, anaplastic oligodendroglioma and glioblastoma against the background of anaplastic astrocytoma 2224 days.

Conclusions. In our work, it was shown that the explant method ensures the production of viable cells of glial tumors and the possibility of their further cultivation.

Purpose: We here aimed to examine the epidemiologic features and treatment outcomes of pediatric pulmonary tuberculosis cases who were registered to the Adana Tuberculosis Dispensaries.

Materials and Methods: Fifty-six pediatric patients aged 0-18 years with the diagnosis of pulmonary tuberculosis were examined retrospectively in terms of demographic data, clinical characteristics and drug susceptibility test results, as well as treatment outcomes. Data were collected through medical record review.

Results: The mean age of the patients was 12.84 ± 5.62 years and 46.4% were female. Nine patients (16%) were aged 0-5 years, 4 (7.1%) were aged 5-10 years, 17 (30.3%) were aged 10-15 years and 26 patients (46.4%) were aged 15-18 years. Fourty-eight children was only pulmonary tuberculosis whereas eight possessed characteristics of both pulmonary and extrapulmonary tuberculosis. The most frequent symptoms were prolonged cough (80.3%) and weight loss (73.2%). Drug susceptibility test was performed only 22 patients. Multidrug resistance was determined in one patient. Among the 56 children for whom treatment outcome was documented, 39 (69.6%) were completed treatment, 16 (28.5%) were cured and 1 (1.7%) had treatment failure.

Conclusion: It was observed that the signs and symptoms of our patients were compatible with the literature. The epidemiological characterization of pediatric patients with pulmonary tuberculosis helps to provide a better diagnostic approach in this population.

An Experimental Approach to Transdisciplinary Methodology in Housing
Authors: Özdamar Esen Gökçe
Published: January 2021

This article explores a transdisciplinary research method derived from the need to determine the tacit knowledge in the re-reading of contemporary housing patterns in Narcity in Ä°stanbul, Donau City in Vienna, and the Eastern Docklands in Amsterdam. The need for the development of such a method derives from two main problems: first, the necessity of re-reading the new dynamics of contemporary housing within the context of changing urban narratives in a globalised world; second, the consideration of the need for a dynamic view that engages both the subject and object in housing research. The residential areas are simultaneously evaluated at three levels defined by Basarab Nicolescu through an experimental and three-dimensional surface and inquiry space. It is projected that this methodology can help transgress the boundaries between fixed forms of policies and production and help bridge fact and fiction in re-reading and mapping controversies among researchers at different levels of comprehension.

Authors: ZEHTAB NAYEBİ Masoumeh , TURGUT Zeynep
Published: January 2021

Identification systems have become biometric-based, especially with the increase in the performance rates of machine learning methods. Biometric identification systems offer a high level of security by using reliable, difficult-to-change parameters. In this thesis, a biometric identification system is proposed using dorsal hand vein patterns. The relevant system has been tested on the sample dataset in the literature. The number of data were increased by adding noisy data to the data set used. The classification was made on the preprocessed images using SVM, ANN, LDA + KNN, and CNN methods. It has been determined that the highest identification accuracy is achieved when CNN is used, and CNN method provides higher performance compared to other methods. With the proposed identification system, after multiple runs, an average accuracy of 99.64% is achieved with the CNN machine learning method.

Authors: Debbarma Swapan
Published: January 2021

Burn injuries are the second major cause of trauma-related deaths only exceeded by motor vehicular accidents, both in the developing and developed world. Burn due to flame or fire is common in this region.

To find out epidemiological patterns and cause of death in the flame burn as data on it is not available even though the most common cause of burn in this region.

This cross-sectional observational study was carried out at the Department of Forensic Medicine, Assam Medical College, Dibrugarh from 1st July 2014 to 30th June 2015.

A total of 224 cases died of flame burn brought for autopsy were taken for study. A thorough post-mortem examination was done on every case following standard procedure. Data were recorded in the proforma especially prepared for this purpose.

Out of 1436 medico-legal deaths, 224 (15.60%) was due to flame burn. The majority of victims were female 186 (83.03%), married, and belong to 21-30 years of age group. Victims were mostly from rural areas, unemployed, and literates. Kitchen 129 (57.60%) was the main place of occurrence. The majority suffered more than 80% burns of TBSA and died within 24 hours 92 (41.07%). The hypovolemic shock was the most common cause of death.

Until the economic condition is improved and lifestyle changes among the people, the fire-related problem must rise in countries like India.

Young age groups and unemployed were most among victims. Burn incidents decrease with increasing education level. Economic improvement and change of lifestyles will help in reducing burn-related problems.
relationship between international trade and immigration policies

This paper concerned is how the Trump administration treats Mexico as Testing Ground in term of trade and immigration two major subjects on which the US president promised a radical policy shift. The main objective of this paper is to demonstrate that the announcement of the new immigration law known as the Reforming American Immigration for Strong Employment (RAISE) and the immigration policy as a whole are the reflection of racism and white supremacy of the Trump administration. the current account deficit between Mexico and the United States has been used as an anchor for the immigration policy. We will also analyze the realistic theory of international relations, according to which, power is at the center of all types of freed trade agreements.
We point to these following structural problems (i); the racism and white-nationalism in the Trump administration, (ii) the causes and consequences of power and the degree of exploitation in the trade relationship between Unites States and Mexico, (iii); the Trade deficit reduction of US with NAFTA partners is not a reflect of Fair Play in a World Trade and therefore is unsustainable in the long term, and (iv); The Gross Domestic Product (GDP) growth in the first quarter of 2019 (3.2 percent) of the United States is not the measure of the economy or import tariff, it is a result of a big corporate tax cut which necessarily mean a higher corporate benefits.

H-Rotation: Secure Storage and Retrieval of Passphrases on the Authentication Process
Authors: Touil Hamza , El Akkad Nabil , Satori Khalid
Published: January 2021

Passwords/passphrases can be either system generated or user-selected. A combination of both approaches is also possible—encryption created by the system and assigned to the user by the information system meeting the policy requirements. Policy rules can be designed to increase security and usability factors, such as information storage and retrieval. This paper proposes an algorithm dedicated to the security of passphrases in an online authentication, so the passphrase entered will be stored in a remote database. Through an SHA-3 hash function, the system must hash the pass phase. Before storage, the system must apply random rotations on the already generated HASH while eliminating any traceability performed on the different transactions performed. To prevent the hacker from using them recurrently if he wants to attack our database. Then the system must recover the real HASH and then the passphrase based on the data provided by the user in the form of codes.

The results show that: (1) there is a significant positive correlation between social anxiety and cell phone addiction among college students; (2) just world belief plays a regulating role in the relationship between social anxiety and cell phone addiction. with the improvement of just world belief, the relationship between social anxiety and cell phone addiction gradually weakens and eventually disappears.
Factors Supporting or Hindering the Place-based Structure of Commons in Local Productive Systems
Authors: Bellandi Marco
Published: January 2021

Recent results on the relationship between external economies and local public goods may be summarised as follows. Marshallian external economies are at the core of paths of development in vital local productive systems, such as Marshallian industrial districts or similar forms. They are partly external to the resources organized by single specialised firms and largely dependent on the embeddedness of the firm in the system and its various forms of division of labour. Exchanges need to integrate the contributions of the specialised producers, but all sorts of difficulties hinder them if a joint access to ‘local’ public goods does not help producers. Markets do not provide for them easily, nor top-down State planning does. Mechanisms and processes of local governance and place leadership, possibly combined with social customs and conventions, are an important support to local integration. The paper comes back to this kernel in the theories of local development, proposing an extended framework of relevant local public goods, qualified as specific public goods, club goods, and place-based common-pool resources, all sharing “commons”-like features. Factors hindering virtuous circles between external economies and specific commons are considered as well, in particular those related to different structures of interests
IDENTIFYING BEST-PRACTICE STRATEGIES FOR MANAGING RESIDENTIAL CAREGIVERS WORKING WITH CHILDREN AT RISK
Authors: Reznikovsky-Kuras Anna , Gerasimenko Anna
Published: January 2021

Residential caregivers are the central figures responsible for the children in their charge. Their work is physically and emotionally taxing, and carried out under pressure: they are prone to burnout. In addition, their status is lower than that of other staff. This study aimed to identify the strategies to improve caregiver functioning that have been adopted in Israel’s residential social-service facilities, and to examine the extent of their implementation. A two-stage, mixed-methods study design was employed. In the qualitative stage, six successful care facilities were identified; their directors were interviewed in depth using the Learning from Success method. In the quantitative stage, a survey was administered to 95 directors, using open and closed questions. Six best-practice strategies for working with caregivers were identified: careful screening, training, ongoing supervision, personal and professional support mechanisms, flexible schedules, and a clear work plan and procedures. While these strategies were applied to some extent in most facilities, they varied in scope and implementation. Using a regression model, we found a connection between the implementation of these strategies and the directors’ satisfaction with the caregivers’ work. We discuss recommendations that can help directors incorporate the six strategies in residential homes and meet the challenges directors face in their work with caregivers.
SYSTEMIC REFLEXIVITY IN RESIDENTIAL CHILD CARE: A PEDAGOGICAL FRAME TO EMPOWER PROFESSIONAL COMPETENCE
Authors: Formenti Laura , Rigamonti Allessandra
Published: January 2021

This position paper offers a pedagogical frame to empower professional work in residential child care. Jobs in this demanding field are characterized by daily relationships with children of different ages, needs, and cultural backgrounds. There is a need for effective communication and interaction with them, their families, co-workers, other professionals, and care agencies, as well as with the larger community. This complexity brings uncertainty and the necessity of thinking and acting in a sensitive way in order to open possibilities for systemic transformation at the micro, meso, and macro levels. In this framework, we focus on reflexivity as a meta-competence — a set of specific postures, competences, and attitudes that characterize expert professional action. A thorough literature review on reflexivity in social work and child protection is aimed at clarifying the meanings, uses, and features of this concept. We claim that systemic reflexivity can be used as a framework, a methodology, and a set of tools to empower professional work by enhancing emotional, cognitive, and epistemic self-awareness, systemic wisdom, abduction, and active listening. To help workers and teams develop these five competences, a self-directed learning module is currently being designed, based on systemic and narrative perspectives, and transformative learning theory.
Gobierno abierto en México: implantación y contraste con un modelo ideal
Authors: Soria Romo Rigoberto
Published: January 2021

En este artículo se estudia la implementación del gobierno abierto en México en sus cuatro pilares: transparencia, participación ciudadana, colaboración y rendición de cuentas. Se contrastan sus avances con un modelo de inspiración weberiana. La hipótesis plantea que, ante un entorno contradictorio y en ausencia de capacidad institucional, y de condiciones adecuadas en su implementación, el gobierno abierto terminará siendo un “vestido de aparador” o mito racionalizado que dejará intactos los problemas que pretende solucionar. Para probar dicha hipótesis, se propone un marco teórico sobre el tema, y un método que permite generar resultados contrastables y replicables en el futuro.

The objective was to evaluate the effect of two methods of freezing on seminal quality and effect of seminal plasma as an inducer of ovulation in pregnancy percentages in inseminated alpacas. The semen collection was made post copula. After the collection of the ejaculates, motility and volume were assessed. The ejaculates with volume (≥1 ml) and motility (≥ 60%) were mixed (pool), 80 % was used (3 samples/pool) and 20 % (2 samples/pool) during the experiment. Then and diluted in Tris-base with 20% egg yolk. The samples were cooled 1.5 hours at 5 °C. At that temperature it was combined with the basic dilutor plus glycerol, obtaining a final concentration of 5% glycerol, then they were packed in 0.5 mL (13 x 106 spem/straw) straws to be frozen by horizontal and vertical methods. The seminal (semen + vaginal fluid) quality analysis was performed fresh and after cooling and thawing. Insemination was performed in two groups with thawed semen from two straws of the vertical method, the first group 20 females induced to ovulate with GnRH analog, the second group 20 females induced to ovulate with seminal plasma. When comparing, the results obtained of motility, viability, HOST and acrosomal integrity of fresh sperm, after the freezing process, decreased (p<0.05) compared to fresh and refrigerated samples. On the other hand, when comparing the freezing methods, the sperm values frozen by the vertical method were higher than those obtained by the horizontal method, with (p<0.05) in motility and HOST without (p>0.05) in acrosomal integrity and viability. The vertical semen freezing method can replace the horizontal method to obtain pregnancy.

The objective of this study was to investigate the immunocastration using against gonadotropin-releasing factor (GnRF) with Bopriva® (Zoetis) on the performance of production variables, meat quality, docility, and scrotal circumference in young rams, from Sheep production center “Tupac Amaru”, Junin region, Perú. A total of 60 animals were divided into four treatments: T1, T2, and T3 with 0.50 mL, 0.75 mL, and 1.0 mL of doses with Bopriva®, respectively, and T4 (control - 1.0 mL of placebo (distilled water)), with fifteen animals in each. The variables were measured every 15 days for three months (September to November 2018). Datasets were assessed by one-way ANOVA and subsequent posthoc Tukey´s test to detect significant differences among treatments. The results indicated differences found between treatments with the immunocastration compared with non-castrated animals for final weight, carcass weight and performance, scrotal circumference, and docility. Growth performance and meat quality characteristics were not adversely affected by immunocastration. Likewise, immunocastration with Bopriva proved to be effective to stop scrotal development and consequently reduces the sexual and aggressive behavior of young rams. The dose of 0.5 mL seems to be adequate due showed better performance for most variables compared to other treatments

The aim of this study was to determine the morphological and morphometric characteristics of guinea pig sperm (Cavia porcellus), using an image analysis system. Semen from collected from five type 1 guinea pigs, four months old (1.19 ± 0.15 kg) by electroejaculation method, between 3 and 5 times for each animal, making a total of 22 adequate collections. The volume, pH, sperm concentration, total motility and percentage of live sperm were determined. The samples for the analysis of sperm morphology and morphometry were stained with Spermac® and analyzed using the Motic Image Plus® software. The morphology was analyzed according to the dynamics of its acrosomal reaction, distinguishing 4 classes. The length, width, area, perimeter, ellipticity, elongation, regularity and rugosity of the head of the guinea pig sperm were determined, as well as the midpiece length and the tail of the spermatozoa. Guinea pig sperm morphology was analyzed with a complete random design, and the morphometric parameters by random blocks, using Duncan's test to compare means in both cases. In relation to morphology, significant differences (P <0.05) were found in the percentage distribution of classes, the most recurrent being class 2 (41.67%), higher than the other 3 groups. An animal effect (P <0.05) was found in the morphometric variables of head and midpiece of guinea pig spermatozoa. The morphometric measurements of guinea pig spermatozoa were: length (7.45 ± 0.29 µm), width (6.55 ± 0.25 µm), area (43.02 ± 3.03 µm2), perimeter (26.56 ± 1.07 µm), midpiece length (12.02 ± 0.70 µm) and spermatozoa tail length (92.96 ± 3.96 µm).

Ankle sprain is the most common injury in performance sports. Two of the most common residual symptoms of an ankle sprain are: the occurrence of chronic joint instability and agonist-antagonist muscle imbalances, expressed numerically by the values ​​of the muscle coactivation index. The purpose of the research was to demonstrate that the use of proprioceptive exercises leads to the improvement of the degree of chronic joint instability and of the values ​​of the muscle coactivation index. The research had a number of 22 subjects, handball players, whose age was between 15 and 16 years. The degree of joint instability was established by using the “Foot and Ankle Disability Index” Questionnaire, while the values ​​of the muscle coactivation index were calculated following the electromyographic measurements. The obtained results highlight the efficiency of the proposed proprioceptive exercise programme, the statistical significance of the obtained results (by improving the initial and final values), as well as the existence of correlations between all evaluated parameters (muscle coactivation index, number of ankle sprains and degree of joint instability). The conclusions of the research underline the efficiency of proprioceptive exercises in diminishing the degree of chronic joint instability and in improving the values ​​of the muscle coactivation index. Based on the results obtained, the research acquires an important practical value, because the proposed intervention programme has applicability in all sports sectors.

In athletics, strength plays a special role, given that its development is focused on improving the speed of movement. The main form of expressing strength in athletics is speed-strength (explosive strength, take-off), which is representative for sprinting, jumping and throwing. Specialised studies have revealed that one of the most effective training methods used to develop explosive strength, also called explosive power, is the training based on plyometric exercises, but studies regarding the use of this method for the prepubertal age segment in athletic training are scarce. The purpose of this research is to investigate the degree of improvement in explosive strength in preadolescent athletes with the help of weekly plyometric training as compared to the control group. The research was carried out at the School no. 190 between 20 February and 17 June 2017. In order to conduct the experimental research, 42 athlete subjects of both genders, aged 11 to 13 years, were investigated. The experimental group was made up of 20 athletes, members of the Municipal Sports Club in Bucharest. The control group included 22 athlete subjects of both genders, who were trained by other coaches. Both groups performed four training sessions per week for 17 weeks. Analysing the results of the experiment, we can conclude that plyometric workouts contribute to the development of lower body strength in preadolescent athletes.

The objective of this case study is to observe the existence of an anticipation mechanism at the muscle groups level of the upper limbs. We tried to highlighted this anticipation process by measuring the potential of surface electric for some muscle groups representing the kinematic chain on the right side, involved in the motor action of catching a basketball and a 3kg medicine ball with two hands to the chest. We conducted a case study of a 13-year-old child, female gender. As a measurement method, we used surface electromyography signals of the EMG Trigno Delsys wireless system with 16 electrodes. We determined the moment when the muscles come into action by increasing the potential of surface electric and the moment when the action of catching the ball takes place, using the information provided by the accelerometers incorporated in the sensors of the Delsys equipment used. Therefore, we obtained information about how different muscle groups come into action which helped us to get an idea of how the child's movement is structured. Based on results of accelerations and EMG signals acquired we have formulated conclusions regarding the neuromuscular control of the tested subject. We also planned for the future to test a larger group of participants in the study research of anticipation mechanism in children who do not practice any performance sports.

The consolidation of topsin, the most prolific technical & tactical element in the attack’s area, requires, besides the daily training and efficient biomechanics, an optimal health of the osteo-articular and muscular system, due to the fact that the performance of this element requires forceful speed developed throughout the muscle chain. The purpose of the present scientific research is to identify the problems occurred at spine level resulted following to topspin attack and the importance of this technical element in the female junior’s performance. The social enquiry-based survey was conducted on a number of 27 coaches and athletes, using a number of 15 questions. Objectives: optimization of topspin attack in 11-12 years old female juniors. Premises: the knowledge on statistics of spine specific areas generating pain at the time of the attack will allow us to create a postural correction program meant to optimize performance. Research methods: The registration method was based on an opinion poll, on a statistical and mathematical method, on computer graphics method. Conclusion: around 78% of the interviewed specialists consider that the lumbar area is the most affected and predisposed to pain in case of topspin, existing a strong correlation between it and the technical element considered to be the most important in the attack phase (topspin – 66.67%) in female juniors, p = 0.003 < α = 0.05, V = 0.620 and C = 0.659.

The pathology of autism dates back to the 1900s, being framed within the broad sphere of neuropsychological conditions. So far, the autism spectrum disorder (ASD) has passed through various pathologies, from socio-emotional disorders to schizophrenic disorders. The clear distinction between childhood autism and childhood schizophrenia was only made in the early 1980s. ASD is one of the most common invasive developmental disorders; defined as a neurological condition characterised by a distortion in the overall development of a person, it affects 1 in 150 children and 4 to 5 boys per girl. The autistic triad brings together qualitative anomalies in social interactions (in verbal and nonverbal communication), restricted interests and stereotypes. The 1980s and 1990s highlight the role of behavioural therapy and the use of highly controlled learning environments as a primary treatment for the forms of autism and related conditions. Promising studies on the role of oxytocin or certain amino acids involved in neurotransmission, especially in regulating stress and its emotional consequences, are currently in progress. Until now, the two therapies have remained primordial along with physical therapy and speech therapy. The purpose of this paper is to present some of the means that can contribute to the pre-integration of children in mainstream education, being also a starting point for future applied research. At the same time, the paper is helpful for the parents of children with ASD, who are given the opportunity to work themselves in the absence of a specialist or financial possibilities.

In executing aerobic gymnastics technical elements, a high level of explosive power is needed, especially at lower-body muscle groups. In addition, to maintain the specific effort during routine length (1 min 30 s - 1 min 45 s), an optimal development of specific endurance training and a high capacity of focusing is required, in order to execute the technical elements with accuracy. The purpose of this study was to elaborate a testing protocol to evaluate the physical effort capacity necessary to perform specific technical elements in aerobic gymnastics. The proposed testing protocol, is aimed at assessing neuromuscular behavior of lower-body muscle action and the physiological demands, in a maximal vertical jump test (MVJ). The neuromuscular assessment of the of lower-body was achieved by measuring the specific vertical jump parameters, respectively the power in the take-off phase (P) and the height of the jump (JH). The testing protocol consisted of three sets of maximum vertical jumps, lasting 30 s each, with a 15 s rest time between sets. For the physiological demands, as a result of test implementation, heart rate (HR) and the blood lactate concentration (La) were measured. The study was conducted on a group of 13 junior level gymnasts, 7 females and 6 males (aged 14-16 years, average height 163 SD 8.1 cm, average weight 50.69 SD 8.47 kg). The results of this study confirm the proposed methodology reflects an objective view of the physical training status necessary for specific effort accomplishment in aerobic performance gymnastics.

The present research is based on the theory developed in 1983 by the American psychologist Howard Gardner, according to which people possess eight distinct types of intelligence: verbal/ linguistic, mathematical/ logical, visual/ spatial, bodily/ kinesthetic, rhythmic/ musical, interpersonal, intrapersonal, naturalist. The way these multiple intelligences are combined differentiates us as humans, for example, in school, students react differently. Some students are more interested in learning, some are not. This may be due to different types of intelligence. Our research aims to highlight the dominant types of intelligence for second year students, depending on which teachers can adapt their teaching methods. The research was carried out over a period of 3 weeks. The participants in the research are 111 romanian students from National University of Physical Education and Sports, out of which 42 are female and 69 are male. The research methods used are: scientific documentation, questionnaire-based survey (multiple intelligences test was applied), statistical-mathematical method, graphical method. The results of the research provide us important data to see to what extent kinesthetic body intelligence is dominant in students practicing sports and what are the other types of intelligence present in athletes. Finding out the dominant types of student’s intelligence can provide us important information according to which we can adapt our teaching methods. Thus, we can conduct our didactic activity in an attractive manner, in which the potential of students is not wasted and feel motivated to learn and evolve in a traditional classroom.
