The electrical circuit of a simulator of pulse high voltage overvoltages with an amplitude of up to 10 kV DC, which is intended for testing the stability of solid-state power converters to emergency conditions according to item 4.9.3.5 of State Standard GOST 33726-2016, is proposed. By using the developed simulator, a high voltage pulse with the required values of amplitude, duration, and rising and falling rates can be obtained. Analytical expressions are derived that describe, with sufficient accuracy, the transients in the electrical circuits of the proposed pulse high voltage overvoltage simulator, which is confirmed by computer simulation carried out in the MATLAB Simulink environment. Based on the obtained theoretical results, a mockup simulator for testing the stability of a high-voltage power converter to overvoltage of a given shape and amplitude has been developed. The results of practical use of the developed simulator on the example of testing the PSN110 U1 auxiliary converter are given. The article may be of interest to specialists who design equipment for carrying out overvoltage tests of solid-state high-voltage converters for both railway transport and industrial applications.

Authors:   All-Russian Electrotechnical Institute – Branch of FSUE ”RFNC – VNIITF named after academ. E.I. Zababakhin”, LARIN Vasily S.
Published: December 2021

In the first part of the article, the results from theoretical studies of frequency responses in a homogeneous chain circuit containing two PI sections were presented, and conclusions about the voltage resonance occurrence conditions were drawn. A circuit with two PI sections has a single independent node and one natural frequency, whereas transformer windings are more complex oscillatory circuits and have a much larger number of natural oscillation frequencies. The second part of the article presents the results from studies of frequency responses in a homogeneous chain circuit containing four PI sections, three independent nodes, and three natural oscillation frequencies. Analytical expressions for the admittances of the equivalent circuit individual parts and the voltages at the intermediate nodes, as well as expressions for the natural frequencies are obtained. Using an analysis of the frequency dependences of the admittances of the equivalent circuit parts, the conditions and frequency ranges under which voltage resonance may occur at the first, second, and third natural frequencies, are shown. It has been demonstrated that for the considered resonant circuits there is a critical frequency above which the conditions for voltage resonance are not satisfied. Formulas for impedances and voltages at intermediate nodes of a chain circuit with an arbitrary number of PI sections are given.

In calculating traction network impedances, the greatest difficulties arise due to the need to take into account mutual inductive couplings between different wires of the multiwire contact system, between the rails, between the wires and rails, and between the contact systems of different tracks. However, no matter how accurate the methods of accounting these couplings are, numerous assumptions and uncertainties result in impossibility to guarantee the calculation of these impedances with an error of less than 5-10%. In taking into account mutual inductive couplings, it is convenient to use a simplified method, in which, instead of considering each pair of conductors, an average dependence for each multiwire network as a whole or an average dependence between two networks are considered. This approach produces virtually no effect on the accuracy of determining the resulting traction network impedances, yet it dramatically simplifies the calculations. A multiwire network can be represented as a set of "conductor-ground" loops. Equations for determining the impedance of the resulting loops are given, in which multiwire contact or rail networks behave as a conductor. On the basis of such loops, it is possible to determine the inductively decoupled impedances of the contact and rail networks for single-track and double-track sections, which are used for drawing up a traction network equivalent circuit. In doing so, the current leak from rails to ground must be taken into account for a rail network, which can be performed by introducing a special coefficient for inductively decoupled rail network impedance. A methodology for calculating this coefficient is presented.

This study examined the extent of fraud prevention mechanisms that influence the awareness of curbing the occurrence of fraudulent activities in public sector organisations, particularly the Federal Ministries in Malaysia. The key factors in this study thereby attributed as the fraud prevention mechanisms that influenced by ethical leadership, internal control system, and fraud prevention programmes. Following this, the Agency Theory was employed to guide the study. A survey was conducted among the officers of various Federal Ministries who were sampled via the purposive sampling method and yielded 210 total responses. The results showed that ethical leadership and the implementation of a virtuous internal control system ranked as the most effective fraud prevention mechanism that influenced their awareness towards curbing the occurrence of fraud. A regression analysis further revealed that the fraud prevention programmes were not statistically significant in influencing awareness of fraud. The main value of this paper is the effect of fraud prevention mechanisms; namely, ethical leadership, internal control systems, and fraud prevention programmes, on awareness of fraud amongst officers in the Federal Ministries in Malaysia. The findings of this study provide useful insights for the Federal government to improve and reconsider current fraud prevention mechanisms, especially fraud prevention programmes to improve awareness of fraud and recover public trust. Keywords: fraud awareness, ethical leadership, internal control system, prevention programme, Malaysian federal ministries
A reflexive exploration of transposing comparative paradigms into scholarly and practical approaches in teacher education
Authors:   North Dakota State University, USA, Salajan Florin D.
Published: December 2021

This article examines the place of comparative and international education (CIE) scholarship and practice in teacher education (T.Ed.). In this regard, CIE scholarship is instrumental in revealing the functioning, organization, importance and interconnectedness of teaching, as a profession, and teacher education, as the conduit to that profession, across national and cultural settings. As teacher education programs and teacher educators continue their work in imparting robust and sound pedagogical knowledge, they also need to acknowledge the enriching nature of a comparative perspective in the scholarship and practice on teacher education. Thus, including comparative methods in examining teacher education both within and across a program’s national borders offers teachers-to-be a window into an array of teaching practices in a global setting. Developing an awareness, interest and inclination toward a comparative perspective-taking in teacher education is paramount in forming the new generations of teachers and researchers on teacher education. At the same time, teacher education programs benefit from research collaborations across national and cultural settings, allowing them the possibility to co-learn what approaches may work in meaningfully adjusting their curricular organization to prepare teachers for an interconnected world in which their students truly become global citizens.

Published: December 2021

Mobile learning (m-learning) has the potential to vastly change and improve education as we know it. Its main advantage is in extending the educational contexts to any place and any time. This leads to possibilities of more active and experiential learning. Furthermore, it greatly improves the potential for communication and access to information. All of these improvements, if utilized properly, can lead to more meaningful learning and more internal motivation for learning. However, these changes are not easy to implement and require the overcoming of several obstacles. This study aimed to investigate the attitudes towards m-learning and its relationships with ubiquitous learning, experiential and active learning, meaningful learning, cooperative learning, internal motivation for learning, and demographic variables. In order to measure these constructs, questionnaires were completed by 200 participants. The results suggest that the youngest generations (15-17 years old) and those who used their mobile phones the most have the highest attitudes towards m-learning. There were no differences amongst genders or people with various levels of education. Furthermore, the effects of mobile and ubiquitous learning on meaningful learning were mediated by collaborative and experiential and active learning. Lastly, the effects of mobile and ubiquitous learning on internal motivation for learning were direct. The findings indicate the importance of utilization of mobile learning and its positive consequences on both academic and personal aspects of the students’ lives.
Using students' reflection in the university educational process - a qualitative approach
Authors:   West University of Timișoara, Romania., Țîru Carmen Maria
Published: December 2021

The university learning process must be self-planned, self-directed, self-initiated, and frequently individually completed. To be able to achieve these goals, the students must have certain knowledge and skills. One of these is the reflective ability, developed through different modalities and using different tools. This article presents a qualitative interpretation of the students' responses written in a reflective journal, at the end of a semester, as a tool for self-assessment and self-reflection and feedback on the educational activities in which they were involved. We present, anonymously, the dominant answers for each item grouped in reflective dimensions about the teaching and learning process. Based on these responses, we tried to identify characteristics and/or difficulties in the teaching and learning process, not only to summarize and analyze but to value and/or optimize them in the future university educational process.

Working in a challenging academic environment as mathematics professors for the Technical University of Civil Engineering Bucharest, we thought to find a teaching strategy that, in addition to the required standard, but also has the standard of attractiveness and accessibility. Why? This is due to the fact that our students have a very nonhomogeneous level of knowledge and logical-mathematical skills. That's how we came up with the idea of organizing each lesson in our courses in a gradual way, and completing them with an informal part. On the other hand, we set out to collaborate with professors working in the departments of other natural sciences or in engineering departments, enriching the mathematics courses with technical applications. This has led to write several didactic works, which also include such applications. Proving the usefulness of this courses, our new work offers two such technical applications for the mathematical analysis course, taught in the first semester and dedicated to the differential calculus of functions having one or several variables. More precisely, we present in a gradual way, two applications solved by using the mathematical modelling: a problem belonging to electricity and then, the cruising speed problem. The gradual presentation begins, for each of these problems, with the necessary notions (organized in the form of two dictionaries, for Math and for Physics, respectively), continues with the statement of the problem, with the solution methodology, and finally, with the solution itself. Our presentation will provide students with a model of logical (mathematical) approach, useful to them in the courses of other natural sciences and of engineering disciplines that they will study later. In addition, it will prove them why mathematics is a fundamental discipline for the engineering education.

Communication in the online environment represents a real evolution for the whole society, hence for the educational system but because the whole change took place in a short span of time, the education has faced an unencountered challenge up to now. Component of the informational society, the educational dynamic and open system promotes nowadays ways of achieving the instructional educational process, offering to the teacher a multitude of organisational and functional variants. However, in the case of children with special educational needs, there are many barriers in the way of achieving their right to education in the virtual space. The present study consisted of achieving an inquiry-based questionnaire, applied to the teaching staff who works in inclusive education centres and to those who have students with different deficiencies and special educational needs in their class. The results of the study highlight both the difficulties and the opportunities of achieving a didactic activity in the online environment for students with special educational needs.
Social-Emotional Development - Highlights in the Romanian Curriculum for Early Education
Authors:   Babes-Bolyai University Cluj-Napoca, Oltean Alexandra Ioana
Published: December 2021

Social-emotional development represents a main developmental domain proposed by the current curriculum for early education in Romania. The main aspects related to this domain are the proper initiation and maintenance of social interactions, the ability to identify and express emotions, to react adequately to the emotions expressed by others, and the self-concept development. Thus, in kindergarten, children learn what solidarity and responsibility for their own actions and for their own behavior mean and that they can control their behavior towards others. All these are essential for the individual wellbeing and learning outcomes, as well as for his future social integration. The Romanian curriculum for early education describes behavioral indicators related to the social-emotional development of children, which can be followed by educators within daily didactic activities. The current study describes the main highlights related to this developmental field found in the main document of the regulatory framework for the Romanian preschool education system. Taking the pandemic context into consideration, we can affirm that educators are required to reconsider the implications of the proper development of social-emotional skills more than before.

Authors: Catenaci Giovanni Felipe
Published: December 2021

Este texto, tem por objetivo demonstrar a repetição como uma potência do esquecimento, tomando como objeto de sua análise o caso da mulher-urso. Para tanto, articularemos referenciais oriundos da Antropologia e da Filosofia. Especificamente, nos referimos ao texto de Nastassja Martin – antropóloga francesa, estudiosa do Grande Norte subártico, atacada por um urso selvagem no ano de 2015 –, publicado recentemente no Brasil sob o título: “Escute as feras” e “Diferença e Repetição”, tese doutoral de Gilles Deleuze. Metodologicamente seguiremos o seguinte percurso: (i) Destacando a noção de perspectivismo, tal como pensada por Eduardo Viveiros de Castro, daremos início às nossas reflexões apontando a imperiosa tarefa xamânica em assumir o ponto de vista dos outros seres. Assim, julgamos ser capazes de introduzir a experiência realizada por Nastassja junto às populações even, nas florestas congeladas da Rússia. Na sequência, (ii) passaremos aos conceitos de repetição, diferença, síntese disjuntiva e devir de Gilles Deleuze, junto a quem buscaremos lançar as bases teóricas para compreensão dos sonhos de Nastassja. Finalmente, (iii) em mãos de tais conceitos, arriscaremos um diagnóstico acerca do acontecimento efetuado no corpo da antropóloga.

Feksofenadyna – przegląd literatury w kontekście skuteczności i bezpieczeństwa
Authors: Sybilski Adam J.
Published: December 2021

Lekami pierwszego rzutu w alergicznym nieżycie nosa (sezonowym i całorocznym) oraz przewlekłych pokrzywkach są leki blokujące receptory H1 (leki przeciwhistaminowe). Jednym z lepiej poznanych i przebadanych leków przeciwhistaminowych nowej, II generacji, jest feksofenadyna. To doustny, długo działający dwubiegunowo, niesedatywny, odwrotny agonista receptora H1 (przyłącza się do tej samej części receptora co agonista, ale wywołuje odwrotny efekt), wykazujący powinowactwo do receptorów histaminowych sprzężonych z białkiem G. Feksofenadynę cechuje minimalny metabolizm w wątrobie i jest wydalana głównie z kałem po aktywnym transporcie do jelita. Skuteczność kliniczna feksofenadyny: poprawa w złagodzeniu objawów alergicznego nieżytu nosa i pokrzywki była oceniana w wieloośrodkowych badaniach, które wykazały jej działanie przeciwhistaminowe, przeciwalergiczne i przeciwzapalne. Feksofenadyna znacznie bardziej hamowała wystąpienie bąbla i rumienia wywołanego histaminą w porównaniu z placebo i lekami I generacji. Liczne badania dowiodły, że feksofenadyna jest bezpiecznym lekiem niepowodującym sedacji, powikłań sercowo-naczyniowych, a jej działania niepożądane (głównie biegunka) są łagodne i szybko ustępują.

Telemedycynę coraz częściej wykorzystuje się do poprawy wyników zdrowotnych w astmie. Nadal nie zostało ustalone, czy ta forma opieki jest skuteczna, zwłaszcza podczas zaostrzenia, jednak pandemia COVID-19 doprowadziła do rozpowszechnienia telemedycyny. Ma ona niezaprzeczalne zalety, jak np. możliwość objęcia opieką pacjentów w miejscach oddalonych od ośrodków miejskich, o dużym rozproszeniu ludności, pacjentów z utrudnieniami w poruszaniu się; oszczędność czasu i kosztów transportu oraz możliwość zastosowania w czasie ograniczeń epidemicznych. W niniejszym artykule przedstawiono możliwości i cele telemedycyny u chorych z rozpoznaniem astmy, uwzględniając okres zaostrzenia. Zaproponowano podstawowe schematy badania przedmiotowego i podmiotowego, ze szczególnym podkreśleniem oznak pomagających w selekcji pacjentów wymagających oceny stacjonarnej.
Possibilities of Preparing Pupils for Proof Problems of Synthetic Plane Geometry Solvable by Deductive Methods
Authors: Zlámal Vojtěch
Published: December 2021

Proof problems, especially the ones of the synthetic plane geometry solvable by deductive methods, play a significant role in mathematical education and due to their demanding principle also in the above-standard education including mathematical competitions. Therefore, the issue of preparing pupils for solving the proof problems is very important. This study aimed to find out if the contemporary state of the system of pupils’ preparation for synthetic plane geometry proof problems is sufficient enough for the mentioned purpose. From the full set of schools of the Czech Republic, there were 14 schools identified as the successful ones based on the results of the national round of the Mathematical Olympiad. These schools were asked questions about literature used for pupils’ preparation and the publications named in the answers were then deeply inspected. The results showed a narrow range of the literature used by the schools and the didactic-methodical inspection of stated literature detected considerable space for improvements which led the author to the main theme of his dissertation.
Grassland bird species in mountain pastures Zaprikraj and Zapleč in the southern Julian Alps, Slovenia
Authors: Bordjan Dejan
Published: December 2021

Grassland birds were surveyed in two mountain pastures (Zaprikraj and Zapleč) in the southern part of the Julian Alps, Slovenia. The survey was carried out during the mornings between 26 and 30 June 2005. Due to the incomplete survey (only one visit, no nocturnal or targeted surveys and late season survey), the surveyed birds’ breeding density is only a rough estimate. 167 pairs belonging to 12 species were counted, with Tree (average density of 1.64 p/10 ha) and Water Pipit (average density of 1.60 p / 10 ha) being the most abundant. Both were observed in all altitudinal belts. The highest density in individual altitudinal belt was calculated for Red-backed Shrike Lanius collurio (3.78 p/10 ha) and Water Pipit (3.61 p/10 ha). In well preserved grasslands in the study area, most species reached high breeding densities compared to other parts of Slovenia and all were recorded higher than during the 1992 survey, although still mostly within limits of the elevations elsewhere in Slovenia. Breeding density of Skylark Alauda arvensis decreased with the elevation. Whinchat Saxicola rubetra, Skylark and Red-backed Shrike used significantly gentler slopes, while Pipits showed no preference for particular slopes.

Authors: Wojciechowska Katarzyna , Walczak Adrianna , Rostowska Ewelina , Poleszak Ewa
Published: December 2021

The objective of this paper was to evaluate and compare the rheological and sensory properties of six natural cosmetic creams that use ECOCERT certificated emulsifying bases: Beautyderm, Dub Base Expert, Simulgreen™ 18-2, Olivem 1000, Montanov L and Emulgin Succro against two synthetics: Granthix APP and Lanette W.

The use of emulsifying bases in formulas helps to stabilize the product and improve its rheological and sensory attributes. In this study, the physical and chemical properties of several prepared cosmetic creams were determined. Apparent viscosity and thixotropy were evaluated by viscosimeter, while spreadability was ascertained by extensometer. Moreover, a group of 10 trained members evaluated the sensory properties of the formulas. The obtained formulas based upon natural emulsifiers are characterized by very good physical and chemical properties, high stabilization and good usage quality. The results were confirmed by sensory analysis. The cosmetic creams made with synthetic emulsifying bases were rated the worst by the study participants, which correlated with the physical tests.

Published: December 2021

Infrared Radiofluorescence (IR-RF) is a relatively new method for dosimetric dating of the depositional timing of sediments. This contribution presents an interlaboratory comparison of IR-RF measurements of sedimentary feldspar from eight laboratories. A comparison of the variability of instrumental background, bleaching, saturation, and initial rise behaviour of the IR-RF signal was carried out. Two endmember samples, a naturally bleached modern dune sand sample with a zero dose and a naturally saturated sample from a Triassic sandstone (~250 Ma), were used for this interlaboratory comparison. The major findings of this study are that (1) the observed IR-RF signal keeps decreasing beyond 4000 Gy, (2) the saturated sample gives an apparent palaeodose of 1265 ± 329 Gy and (3) in most cases, the natural IR-RF signal of the modern analogue sample (resulting from natural bleaching) is higher than the signal from laboratory-induced bleaching of 6 h, using a solar simulator (SLS). In other words, the laboratory sample bleaching was unable to achieve the level of natural bleaching. The results of the investigations are discussed in detail, along with possible explanations.

Published: December 2021

The quality of the financial aplication is highly dependent on the organizational environment in which the information system is used. This concept is in line with the facts found in the field that until now the quality of accounting information system applications used by various companies is still relatively low because they often experience errors and are not well integrated which have an impact on the low quality of accounting information. This study aims to determine whether organizational environmental factors in this case represented by organizational structure and culture still have an influence on the quality of accounting information systems. This research uses descriptive verification method. The sample size in this study was 30 employees of operational units who use accounting information system applications at state-owned banks with branch offices in Bandung, this study uses primary data collected by distributing questionnaires. Statistical testing used is PLS SEM and hypothesis testing using PLS 3.0 smart software. The results of this study indicate that there is consistency with the results of previous studies that the increasing implementation of organizational culture has an impact on increasing the quality of accounting information systems, and the more effective organizational structure has an impact on the quality of accounting information systems.

Published: December 2021

Self-perception is the level of competency at which individuals evaluate themselves in certain areas or domains (Marsh & Shavelson, 1985). An individual’s self-perceptions contribute to their global self-worth and even predicts performance (Cuellar, 2014; Harter & Neemann, 2012). This study measures self-perception scores, as well as experiences with racial discrimination, of 306 NCAA Division I college athletes using the Self-Perception Profile for College Students (Harter & Neemann, 2012). Scores are compared across race. Findings suggest that White college athletes have significantly higher self-perception scores than college athletes of color - with recent discrimination (within the last year) as a significant predictor of multiple areas of self-perception. The implications of this study suggest that faculty and other campus stakeholders should pursue positive relationships with the college athletes they encounter. Positive relationships between college athletes and faculty may help raise college athlete self-perceptions, and in turn, performance in a variety of areas.

Concussions have recently become an area of concern among the general public, but a clear understanding of their total consequence is still being developed. Symptoms of concussions are wide-ranging, encapsulating a plethora of cognitive and emotional abilities that could be affected. Concussions transiently disrupt neural activation as well as behavioral responses across multiple categories. Skills pertaining to various aspects of emotions are often affected yet have rarely been studied after concussions. We present two case studies of collegiate athletes with a history of multiple concussions. This paper highlights the case of a collegiate athlete who had obtained two previous concussions with the most recent being sustained sixteen days prior to neuroimaging. A second athlete with two lifetime concussions was tested one year after the most recent injury. The current study utilized a novel emotional recognition task to assess the behavioral and neural effects of this injury. A group of five controls responded with high accuracy rates and quick response times to the task. They showed activation in regions of the frontal lobe as well as facial recognition areas of the occipital lobe. The 16-day case subject was impaired in recognizing emotions relative to controls and showed little to no overlap in brain activity for regions involved in emotional face processing. The athlete with a longer post-concussion period also showed residual effects of neural activity alteration when compared to controls with few overlapping active regions. Specific brain regions were activated in this group but not in controls including the sensorimotor cortex, supramarginal gyrus, and lateral occipital cortex. By taking a more individual approach in examination of neural activity post-concussion, we may be able to gain a better understanding of this heterogeneous injury.
A Comparison of Treatment Options for Carpal Boss: A Critically Appraised Topic
Authors: Collins Megan , Rivera Matthew
Published: December 2021

Context: Carpal bossing is a bony growth or mass that typically occurs at the 2nd or 3rd carpometacarpal joint. Carpal bossing is often overlooked placing the patient at an increased risk for pain or injury, such as osteoarthritis or inflammatory joint disease if left untreated. Individuals such as combat sport athletes who experience repetitive trauma to this area are at a high risk to develop carpal bossing. The literature suggests conservative or surgical interventions to manage symptoms. The goal of this systematic review is to synthesize the current literature for clinical knowledge and intervention outcomes for carpal bossing. Methods: A systematic search of the literature was performed across 3 electronic databases (Science Direct, PubMed, and EBSCOhost) to identify articles that investigated the effects of surgical intervention or conservative management for carpal bossing. A combination of the keywords and Boolean operators (Carpal Bossing, Carpal Boss, Surgical Intervention, Wedge Resection, Excision, Conservative Treatment, and Intervention) related to the research question were used. The search was restricted to full text, human studies (including cadaveric studies) research, and manuscripts available in English. Articles were included if they examined the effect of either conservative or surgical interventions for the treatment of carpal bossing. Articles were excluded from the review if the study did not examine carpal bossing treatment options or did not include pain, range of motion, strength, or functional measures of the hand and wrist. Two independent reviewers used the Joanna Briggs Institute Checklist for Case Reports and the Checklist for Case Studies to appraise the quality of the articles. A score of 50% was used to remove low-quality studies. The Strength of Recommendation Taxonomy (SORT) method was used to grade the evidence for the articles included. Results: After the initial search, 10 articles met the inclusion criteria, while 3 were eliminated due to low quality appraisal scores. The average scores for case reports and case studies were 5.5/7 or 7.5/9 respectively. There was a total of 58 participants across the 7 studies. Generally speaking, conservative treatment reduced average daily pain and patients were able to return to full participation within 2 weeks. Conversely, patients undergoing surgical intervention experienced episodic pain, including over the surgical incision, typically averaging 2/10 on the visual analog scale. Findings from the surgical intervention showed inconsistent measurements for wrist/hand strength and range of motion. There is level C evidence on the treatment for carpal bossing. Conclusion: The limited evidence suggests conservative management may reduce pain and improve clinical outcomes. However, clinicians should consider the level C evidence with skepticism as the quality of evidence on this topic is low. Further investigations should be performed with more rigor.

Purpose: Reserve Officers’ Training Corps (ROTC) programs prepare student-civilians to become leaders through strenuous physical and leadership training. Unlike their student-athlete counterparts who have direct access to athletic training services, ROTC cadets may or may not have a healthcare provider available. The purpose of this study was to examine the access to care and reporting behaviors of ROTC cadets with a secondary aim exploring the quality of healthcare service interactions relative to patient-centered care. Methods: An online survey assessed access to care using a self-report tool on the type of medical providers available to the ROTC cadets (n=132, age=20±3 y) dispersed between the Army, Navy, Air Force, and Marines, and their illness/injury history and reporting behaviors. The participants who sought care for an injury/illness also completed the Consultation and Relational Empathy tool to measure the level of patient-centered care by the healthcare provider with follow-up analysis using the Consultation Care Measure tool for all athletic training service interactions. Data were analyzed using descriptive statistics. Results: ROTC cadets reported access to 2±1 healthcare providers including a designated civilian physician (26.5%), athletic trainer (23.5%), and ROTC peer first responder (14.4%). However, 50.8% of respondents stated they were unsure what healthcare providers were available. In total, 22.7% of cadets reported being injured and 26.5% reported being sick/ill while participating in ROTC activities. Of those who stated they had sustained an injury during ROTC, 59.9% seldomly or never reported their injury. The ROTC cadets who sought healthcare expressed they were satisfied with their injury (35.96±10.60) and illness (35.48±13.10) treatment from a patient-centered viewpoint. Conclusions: The ROTC cadets reported a general unfamiliarity with the healthcare providers available to them. Despite the reporting behaviors, the cadets reported being satisfied with the care they received.

This article aims to explain the role of dual agents in bringing about changes in agricultural practices.  Starting from the phenomenon of changing plant species that occurred in Parbotihan Village, Onan Ganjang District, Humbang Hasundutan Regency.  Changes in these types of crops often occur in a short period of time and are followed by most farmers.  These changes sometimes occur without considering the adequacy of land, cultivation knowledge, and capital capacity.  So, often the changes that occur are not profitable for them.  On the other hand, these changes also change the cultivation pattern which requires farmers to learn from the beginning as a consequence of changing the types of plants.  This research was conducted during the research period of my thesis by collecting data through observation and interviews. The selected informants are farmers who are involved in changing practices. The author found that the role of multiple agents such as relatives, friends, skippers, and group leaders with different capacities had a role in influencing farmers' actions. Multiple agents act as initiators, motivators, introductors, educators, and interventors. This research also shows that the social arena as public space becomes an effective arena in exchanging information and influences that encourage practice change.
