Authors: Kim Yumin , Park Sun Kyu , Kim Jong-Ho
Published: October 2022

Heterotopic ossification is defined as the development of mature bone tissue outside normal bone. Osteomyelitis is an infection-related inflammatory disorder of the bones. Although pressure sores accompanied by heterotopic ossification have been reported, there have been no reports of osteomyelitis occurring in proximity to heterotopic ossification. Herein, we report a rare case of osteomyelitis in heterotopic ossification after trochanteric pressure sore reconstruction. We also emphasize the importance of proper diagnosis and surgical approach for this infected heterotopic ossification lesion.
A Systematic Approach to Effectively Treat Chronic Wounds Caused by Self-Harm: Two Case Reports
Authors: Ryoo Hyun Jung , Kim Dong Yeon
Published: October 2022

Non-suicidal self-injury (NSSI) refers to the intentional act of causing physical injury without a clear suicidal intent. Patients in a dissociative state attempt to fulfill an underlying psychological need by inflicting cutaneous wounds on themselves. The mechanisms of NSSI can vary from mild to severe depending on the degree of soft tissue destruction. Self-destructive behavior triggered by psychosis, a different classification of self-injury, may have a variety of drivers, such as hallucination and delusion. Repetitive self-harm often results in chronic wounds and associated infections. As a conventional approach is inadequate for managing self-harm wounds, treating patients who self-injure presents many challenges for physicians. In the presence of hard-to-treat primary disorders, a systematic approach with custom procedures that may deviate from traditional wound management principles should be carried out within an interdisciplinary framework that considers the psychiatric condition. The authors provide several recommendations for appropriate management of chronic wounds caused by self-mutilation. Here, we report the cases of a 47-year-old female patient who presented with NSSI and a 67-year-old male patient with self-injurious behavior of psychosis, respectively.

Authors: Delgado Alejandra Mercedes
Published: October 2022

Este artículo presenta los resultados de una investigación cualitativa en relación al docente orientador en la formación docente inicial en la ciudad de Cruz del Eje. El objetivo fue conocer e interpretar las concepciones de los docentes orientadores y los recorridos pedagógicos que definen el proceso de acompañamiento en el período de residencia. Por las características de este objeto de estudio, se optó por un diseño de investigación cualitativo y de corte descriptivo comprensivo. El conjunto de estrategias metodológicas diseñadas (cuestionarlo con oración incompleta, dibujos, role playing, diagrama) se aplicó en un grupo focal de dieciséis docentes orientadores de nivel inicial y primario con desempeño laboral en escuelas de gestión estatal y privada. Según los resultados, las concepciones de los docentes orientadores que desempeñan su rol en el marco del acompañamiento pedagógico están fuertemente arraigadas a parámetros tradicionales y, con menor fuerza, aparecen concepciones de tendencia constructivista.

Published: October 2022

El presente trabajo propone una lectura analítica de historias de vida, en clave de narrativas, de experiencias de maestrandos y egresados que incursionan durante el período 2020-2021 en la investigación educativa. Se funda en un enfoque interpretativo con herramientas metodológicas biográfico-narrativas de investigación en ciencias sociales. De este modo, la historia de vida se inscribe tanto como perspectiva socioantropológica de registro de diversa información proporcionada por los sujetos cuanto como género documental, aspecto este desde el cual se ponen de manifiesto sus caracteres discursivos.

Los textos ofrecen en primera persona el recorte de un momento vital que -en el marco de la pandemia COVID-19- no solo se hace eco de este suceso de alto valor condicionante de futuras transformaciones, sino que además permite la posibilidad de reflexionar sobre las vivencias, contradicciones, interrogantes y aprendizajes que la experiencia del ingreso al equipo de investigación les permite construir como registro subjetivo.

Published: October 2022

Runoff prediction has a pivotal role in the flood warning system. For
small-sized watersheds, establishing a reliable and efficient model to
forecast flood is multifarious and disorderly work. The ensemble
framework for flash flood forecasting(EF5) provides a new opportunity
for runoff prediction in small basins to model simply and practically.
This paper used the framework to structure a flood forecast model for a
small watershed in Hubei Province, China, where flash floods occur
frequently. Four flood events with unique characteristics were selected
to verify the accuracy and usability of the EF5 model. Evaluation using
real data indicated that the EF5 model performs well in these four flood
cases, with over 0.9 Pearson’s linear correlation coefficient(PCC)
values and over 0.85 Nash-Sutcliffe coefficient of efficiency(NSE)
values during the validation. In addition, the study verify the
influence of the rainfall sources from four distinct interpolation
methods on the model and evaluate the reasons for the significant
differences. Finally, we detected the flood prediction performance of
the EF5 model under various forecast lead time, and further statistical
tests revealed that the EF5 model can maintain PCC of more than 0.9, NSE
of more than 0.7, and flood peak bias(FPB) of more than -0.2 when the
forecast lead time exceeds 3h. Numerous indicators and plots prove the
excellent effect of the model forecast. Considering the convenience and
validity of this framework, the research and verification of the EF5
model in the small-sized basin are of significance to flood prediction.

Authors: Chen Jingsheng
Published: October 2022

In this study, Syzygium aromaticum extract as a stabilizing and reducing
agent was utilized to synthesize copper nanoparticles in the aqueous
medium. Various techniques containing UV-Vis. spectroscopy, FT-IR
spectroscopy, X-ray diffraction (XRD), scanning electron microscopy
(SEM), and Energy Dispersive X-ray Spectrometry (EDS) were used to
characterize the synthesized nanoparticles (CuNPs). On the other hand,
the MTT assay was run to evaluate anti lung cancer activity of CuNPs.
The crystal size of CuNPs, according to the XRD analysis, was 30.73 nm.
Moreover, the uniform spherical morphology ranging from 19.55 to 69.70
nm was detected in the SEM images for the biosynthesized nanoparticles.

Published: October 2022

Introduction: During the early phase of the coronavirus disease 2019
(COVID-19), remdesivir was only approved for hospitalized patients. Our
institution developed hospital-based, outpatient infusion centers for
selected hospitalized patients with COVID-19 who had clinical
improvement to allow for early dismissal. The outcomes of patients who
transitioned to complete remdesivir in the outpatient setting were
examined. Methods: Retrospective study of all hospitalized adult
patients with COVID-19 who received at least one dose of remdesivir from
11/6/2020 to 11/5/2021 at one of the Mayo Clinic hospitals. Results:
Among 3,029 hospitalized patients who received treatment with remdesivir
for COVID-19, the majority (89.5%) completed the recommended the
five-day course. Among them, 2,169 (80%) completed treatment during
hospitalization, while 542 (20.0%) patients were dismissed to complete
remdesivir in outpatient infusion centers. Patients who completed the
treatment in the outpatient setting had lower odds of death within 28
days (aOR 0.14, 95% CI 0.06-0.32, p<0.001). However, their
rate of subsequent hospital encounters within 30 days was higher (aHR
1.88, 95% CI 1.27-2.79, p=0.002). Among patients treated with
remdesivir only in the inpatient setting, the adjusted odds of death
within 28 days were significantly higher among those who did not
complete the 5-day course of remdesivir (aOR 2.07, 95% CI 1.45-2.95,
p<0.001). Conclusions: This study describes the clinical
outcomes of a strategy of transitioning remdesivir therapy from
inpatient to outpatient among selected patients. Mortality was lower
among patients who completed the 5-day course of remdesivir.
FcγRIIIa polymorphism in pediatric immune thrombocytopenia: impact on clinical course and outcome
Authors: Nazir Hanan , Hassanein Nehad
Published: October 2022

Fcγ receptors (FcγRs) is an important family of receptors involved in
the recognition of IgG- coated particles and complexes. Engagement of
activating FcγRs initiates phagocytosis, antibody- dependent cellular
cytotoxicity, and the release of inflammatory mediators. Many systemic
autoimmune diseases are under FcγR control. Immune thrombocytopenic
purpura (ITP) is the most common cause of thrombocytopenia in children.
Multiple pathophysiologic mechanisms contribute to thrombocytopenia in
ITP, including phagocytosis and destruction of autoantibody-coated
platelets. Aim To study the impact of FcγRIIIa polymorphism on
development of ITP in Egyptian children, and its impact on bleeding
severity, response to treatment and disease chronicity. Subjects
and methods: This is a case-control study including 40 patients with
ITP (25 newly diagnosed, 15 chronic ITP) and 20 normal controls. Medical
history and physical examination were performed. Laboratory
investigations included CBC, Coombs test, serum complement and
antinuclear antibody, platelet- associated IgG, ELISA test for H. pylori
antigen in stools, and FcγRIIIa genotyping by PCR. Patients were
followed up for one year to assess severity of the disease and response
to treatment. Results: The high affinity FcγRIIIa genotype (158
V/V) and the heterozygous genotype (V/F) were significantly
overrepresented in ITP patients compared to the control group. There was
no significant difference among ITP patients carrying different FcγRIIIa
genotypes regarding response to therapy with corticosteroids or IVIg,
and FcγRIIIa genotypes were similar in acute and chronic ITP.
Conclusion: FcγRIIIa polymorphism might confer susceptibility
to ITP, however, different FcγRIIIa genotypes did not affect response to
therapy or development of chronic ITP.

Background Most patients undergoing left atrial appendage
closure (LAAC) are elderly individuals with atrial fibrillation (AF) and
many comorbidities, which may elevate the risk for complications
associated with contrast agents with fluoroscopic image-guided
procedure. . Objectives This retrospective study of patients
with AF at high risk for use of contrast agents evaluated the
feasibility and safety of LAAC using Percutaneous and Non-fluoroscopic
procedure with transesophageal echocardiography (TEE) as the only image
guidance relative to those under fluoroscopic image guidance.
Methods From September 2017 to December 2020, a cohort of 126
consecutive eligible patients with AF undergoing LAAC at our center were
retrospectively recruited and divided into 2 groups according to image
guidance modality, namely, a TEE group (n = 32; mean age, 75.4 ± 7.9
years; 25 (78.1%) with stage III chronic kidney disease [preoperative
eGFR, 52.7 ± 8.8 mL/min/1.73m ] and 7 (21.9%)
allergic to contrast agent) and a fluoroscopic group (n = 94; mean age,
65.7 ± 10.0 years). Propensity score matching was used to adjust for
baseline differences. Results Propensity-score matching yielded
25 pairs of patients with similarly distributed age (72.9 ± 6.9 vs. 73.1
± 4.9 years, p = .925), gender (10:15 vs 11:14, p = 1), weight (68.3 ±
11.2 vs. 68.1 ± 12.3 kg, p = .948) and ALT level (20.0 ± 9.8 vs. 22.5 ±
14.2 U/L, p = .482). The LAA was successfully occluded in all patients
with statistically similar success rate (100% vs. 100%, p = 1),
hospitalization duration (5.0 [3.0, 7.0] vs. 5.0 [3.0,
6.0] days, p = .498), and rates of complications: 1 (4.2%)
pericardial effusion and 1 (4.2%) residual shunt in the TEE group, and
5 (20%) residual shunts, 1 (4.2%) pericardial effusion, 1 (4.2%)
myocardial infarction and 1 (4.2%) access-related complications in the
fluoroscopic group. There were no deaths. The overall incidence rate of
all procedure-related complications (6.2% vs . 18.1%, p
= .153) at mean 22.2±4.5 months follow-up was statistically similar.
Conclusion In patients with AF of high risk for use of contrast
agents, LAAC under non-fluoroscopic guidance appears feasible and safe
with similar outcomes to that under fluoroscopic guidance.
DC Traction Power Supply System For Electrified Railway With Ice Melting Function
Authors: Wu Chuanping , Zhu Hongzhang , Wang Wen , Xie Yao
Published: October 2022

This paper proposes a DC traction power supply system for electrified
railroads with ice-melting function, which is used to solve the problems
of power quality and line icing of single-phase AC traction power supply
system. The proposed system consists of a multi-tap regulating
transformer, a DC traction converter, a DC step-down converter, and a
three-phase inverter. The DC traction converter adopts the topology of
input-parallel-output-series (IPOS) uncontrolled rectifier and fully
controlled converter. Its main capacity is assumed by the uncontrolled
rectifier, which has the advantages of low cost, simple structure and
easy to realize engineering applications. In this paper, the voltage
regulating transformer is used for shifting and voltage regulation to
expand the ice melting function, which can be used to solve the icing
problem of the railway traction system. In order to realize the
functions of harmonic compensation, DC-side voltage stabilization and
power distribution in multiple parallel operation of DC traction
converter, this paper proposes a compound control method for traction
converter, which realizes power distribution by droop control with
voltage compensation, voltage stabilization by suppressing voltage
fluctuation by power feedforward control, and harmonic compensation by
harmonic current compensation control. The small-signal model of the
system under this control strategy is also established, and the
stability of the control parameters on the system is analyzed. Finally,
a simulation platform is built to verify the superiority of this
topology and the feasibility of the control method.

Energy needs of the world can be achieved by considering photovoltaic (PV) energy as a large-scale source that has been proved by recent growth in production of PV modules and decrement in their prices. Deserts are in demand for the purpose of energy generation through PV, began utilized by countries too. This article scrutinizes the issue of offbeat energy generation by contrasting the two 100 MW PV power plants analogous in location, environment and installed equipment. Irregularity of performance is conducted and assessed by plane of array (POA), annual deterioration rate, inter row spacing, PV cleaning frequency, equipment losses, temperature and other factors. Actual monthly generation differences of a year are examined considering deterioration rate and vice versa for the two in sight. Inter row spacing and POA are emphasized with sun path plots and eclipse diagrams for maximizing the energy yield.

Authors: Djuric Vanja , Stamenkovic Bojana , Petkovic Ivan , Djuric Luka
Published: October 2022

Background/Aim. Peripheral neuropathy (PN) in systemic connective tissue diseases (SCTDs) represents the apparent disease complications or initial manifestations of clinically undiagnosed conditions. The aim of the study was to identify neuropathies (Ns) and their prevalence, point out the diagnostic significance of some electrophysiological (EP) parameters in patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and systemic sclerosis (SSc), and establish their association with disease activity (DA) and disease duration (DDu). Methods. A prospective study was conducted at the Rheumatology Clinic of the Institute for Treatment and Rehabilitation ?Niska Banja? over a three-year period. The study included 157 patients in total, of whom 61 had R A, 4 0 had SLE, and 56 had SSc. The following parameters were analyzed: age, gender, DDu, course of the disease, and DA index. Moreover, clinical, rheumatological, and neurological examinations, as well as neurology tests, nerve conduction studies (NCS), and laboratory analyses, were also conducted. Results. In the studied population, we were able to identify various forms of Ns (in 28.7% of patients) by NCS. In all three groups, the most prevalent type of Ns was axonal (23.6%), sensorimotor (18.5%), and polyneuropathy (23.6%). There was a significant association between DA and the occurrence of Ns (p < 0.001) in the total population. The most important EP parameter was the sensory nerve action potential amplitude of nervus peroneus superficialis [in 70 (44.6%) patients] and nervus suralis [in 35 (22.3%) patients], and compound muscle action potential amplitude of nervus peroneus [in 32 (20.4%) patients]. DDu in all three groups was longer in the population of patients with Ns. Conclusion. Ns are most common in patients with longer DDu and higher DA. The EP method is important in detecting Ns, especially in the early detection of subclinical forms of Ns and the prevention of disease complications.
Pseudotumor as adverse local tissue reaction due to implant corrosion
Authors: Vukadin Ognjen , Dzudovic Jelena , Repic Aleksandra , Bascarevic Zoran
Published: October 2022

Introduction. The term adverse local tissue reactions (ALTRs) is used to describe pathologic tissue conditions appearing after total joint replacement, and it includes osteolysis, bone necrosis, muscle necrosis, cystic lesions, excessive fluid collections, soft tissue masses, pseudotumors, metal sensitivity, metallosis, and chronic inflammatory lesions. ALTRs are rarely described in the literature after the breakage of the ceramic components of the hip prosthesis. Case report. We present a case of a patient with massive fluid collections filled with metallic and tissue detritus, along with signs of systemic cobalt (Co) and chromium (Cr) intoxication. Symptoms developed after revision of the acetabular component with the application of a metal-on-polyethylene coupling. Previously, several revisions were made due to breakage of the ceramic components of the endoprosthesis and instability of the hip. After removal of pseudotumor masses and revision of all components of the endoprosthesis with implantation of a coupling between the ceramic head and the polyethylene insert, there was a significant drop in the serum values of Co and Cr. Conclusion. Trunnion damage should be assessed during revision procedures, and if present, both prosthetic components should be replaced to prevent disastrous effects of metallic corrosion, ALTRs, and systemic metallic ions intoxication. Measurement of serum levels of Co and Cr in patients after joint replacement could identify patients at risk for the development of ALTRs and metallosis.
Ideal fundaments of the history of education as teaching disciplines in Serbia in the 19th century
Authors: Vujisic-Zivkovic Natasa
Published: October 2022

The subject of this article is the ideological basis on which the study of
the history of pedagogy in Serbia in the 19th century was based. The aim of
the paper was to analyze the scientific and socio-ideological starting
points in the conception of the history of pedagogy in Serbia. As a teaching
discipline, the history of pedagogy in the research period was placed within
the framework of professional education of primary school teachers and
pedagogues. Therefore, the goals and tasks of the history of pedagogy were
adjusted not only to the achievements of this scientific discipline in
Europe at the time, but also to the projected goal of the overall education
in Serbia. Textbooks on the history of pedagogy published in this period
(until 1902) represent the basic source for the anal?ysis of the ideological
foundations on which teaching in the field of the history of education was
based. This analysis shows that the history of pedagogy was understood as a
suitable means of harmonizing the spread of Christian principles with a
?rational educational approach?, so that over time there was an increasingly
professional reflection on the possibilities of using educational theories
in pedagogical practice. At the same time, there was a growing awareness of
the influence of general cultural history on the development of pedagogical
theories, as well as the importance of the national pedagogical heritage.
Deep learning-based penetration depth prediction in Al/Cu laser welding using spectrometer signal and CCD image
Authors: Kang Sanghoon , Kang Minjung , Jang Yong Hoon , Kim Cheolhee
Published: October 2022

In the laser welding of thin Al/Cu sheets, proper penetration depth and wide interface bead width ensure stable joint strength and low electrical conductance. In this study, we proposed deep learning models to predict the penetration depth. The inputs for the prediction models were 500 Hz-sampled low-cost charge-coupled device (CCD) camera images and 100 Hz-sampled spectral signals. The output was the penetration depth estimated from the keyhole depth measured coaxially using optical coherence tomography. A unisensor model using a CCD image and a multisensor model using a CCD image and the spectrometer signal were proposed in this study. The input and output of the data points were resampled at 100 and 500 Hz, respectively. The 500 Hz models showed better performance than the 100 Hz models, and the multisensor models more accurately predicted the penetration depth than the unisensor models. The most accurate model had a coefficient of determination (R2) of 0.999985 and mean absolute error of 0.02035 mm in the model test. It was demonstrated that low-cost sensors can successfully predict the penetration depth during Al/Cu laser welding.

Meet a claim is quite difficult in real production, even in specialized drilling manufacturers. Therefore, the development of reliable criteria for approaches to improving the technology of tricone drill bits is an urgent problem. This is great practical importance for domestic enterprise. The task is set to create rock-destroying insert in the basis of the developed construction. This allows you to increase the reliability of the connection between the cutter insert and the body of the cone. Favourable conditions should be provided for the rational distribution of contact stresses in conjugate surfaces "carbide cutter insert – bush – body of cone". Crucial part here is required rigidity of the carbide cutter insert. Advanced requirements are placed on them regardless of the design and dimension-type of tricone drill bits. They must have higher requirements such as: high reliability, durability of responsible elements of support and rock-destroying equipment, productivity, ability is stand destructive forces and torque are brought through a bit for influence on a face This increases the reliability of its connection with the body of the drill bit. Requirements apply to the design to provide favorable conditions for the rational distribution of contact stresses in conjugate surfaces "carbide cutter – bush – body of the bit cone". The obtained results of stress state modeling indicate that, as expected, with the same forces acting on the insert cutter from 42 kN to 57 kN, the most intense place on the cone will be the "collar" near the cutter. The intensity of stress will be up to 1050 MPa in this place for cones with serial rock-destroying equipment. At the same time, the intensity of stress will be up to 900 MPa for cones with developed destructive equipment, this is 14 % less.

The formalized algorithm of calculation of rectangular matrix of press-form is developed on durability and inflexibility with the purpose of determination of optimum geometrical sizes which would provide it optimum operating capacity. For this purpose CAD and CAE systems were used, in particular Solidwork, Matcad. А three-dimensional model of the mold matrix was designed. Research and analysis of the stress-strain state of the matrix was carried out and its optimal parameters were determined. As a result, it makes it possible to optimize the structure of the matrix in terms of stiffness and stability and ensure its optimal performance.
Notes on Urban Planning, Landscape and Architecture of Nabataean Petra Paradigm
Authors: Haddad Naif Adel
Published: October 2022

Hellenism was a real cultural force in Nabataean Petra's urban planning and architectural products. Petra is a paradigm of our knowledge of how the Nabataeans designed and built their urban settlement. In approaching the city, one immediately notices how they planned the city to maximise and take advantage of the accessible majestic landscape topography. They created an extraordinary metropolis in the city centre and the surrounding sandstone mountains. There are many aspects of the particularity and creativity of Nabataean culture during the Hellenistic and Roman periods. In the Nabataean Petra paradigm, we can observe the following: cultural interaction, cultural interchange, cultural exchange, cultural adaptation, and cultural sharing, which acted as cultural links between the peoples of the east and west. Thus, creating a new expression and direction of the cultural sharing between the East and West. Metropolitan cities, as in the case of the Nabataean Petra, are focal points where these changes and their effects are experienced significantly.This paper attempts to shed light on the functional, structural, typological, and morphological conceptions and aspects of the urban development and architecture of Nabataean Petra, particularly in the public spaces of the city centre and the surrounding tomb architecture. It argues that this development and formation was the expression of the highly developed self-image of the citizens of Petra reflected in its urban planning, landscape, architecture, and cultural significance.
The Impact of Audit Culture and Internal Control Systems on Audit Quality: The Case of Lebanese Banks
Authors: Diya Lama
Published: October 2022

The audit process is a representation of the engagement team's testing procedures. A company's culture and working procedures are two factors that might affect one's performance on the job. Leaders may message that they care about their and their audit firm's reputations by showing appreciation for high standards of audit quality and stressing the necessity of "doing the right thing" in the public interest. The Center for Audit Quality is only one part of the Audit Quality Disclosure Framework. There should be a clear emphasis on audit quality, and leaders should set the tone by doing so themselves. Only 300 employees from the businesses above participated in the research. Those 288 employees work for a wide variety of companies. This study’s findings shed light on the connection between strong internal controls and good governance in Lebanon’s banking sector. Senior management will focus on organizational compliance, the internal control system and monitoring methodologies, effective corporate governance, risk assessment, quality assurance, and independent forensic investigation since these are all prerequisites for an independent audit role. The chance of management undermining internal controls designed to identify and prevent fraud will decrease, and a more positive culture will result. Both managers will check that sufficient internal procedures are in place to safeguard corporate property.

Published: October 2022

DanceSport is a mix between art and sport as it combines an elaborate way of communicating the artistic movement fully synchronized to the character of the melodic line and the competitive character. This special activity is in a continuous transformation through the evolution of technical nature and complexity of dance elements/dance figures, with regulations that constantly adapt to the present time and society, constantly offering an amazing show.
The purpose of the research is to structure the DanceSport judging systems, the problems that have arisen over the years and the changes that took place regarding the evaluation of dancers.
The evolution of the judging systems and the criteria reflect the evolution of dancers over time, an evolution that became vital because of the technical/artistic nature of transformation and also, because of the complexity of the choreographies or dance routines.

Penelitian ini bertujuan untuk menganalisa apakah pelaksanaan pengendalian intern persediaan barang dagang pada Toko Cereal Kota Metro sudah efektif dan sesuai dengan prosedur yang ada. Jenis penelitian ini adalah deskriptif kualitatif, sedangkan untuk pengumpulan data dalam penelitian ini adalah observasi, wawancara, dan kuesioner. Hasil dalam penelitian ini adalah pada Toko Cereal Kota Metro sudah terdapat struktur organisasi yang cukup jelas dalam hal-hal apa saja yang harus dikerjakan. Namun dalam pelaksanaannya memang belum efektif sehingga karyawan terkadang masih mendapatkan rangkap tugas yang dapat membuat karyawan tidak fokus dalam melakukan pekerjaan yang sedang dilakukan dan dapat mengakibatkan kesalahan catat dan kesalahan lainnya. Hal ini mencerminkan belum adanya prinsip pemisahan fungsi yang baik.Pelaksanaan informasi dan komunikasi serta peantauan didominasi oleh pemilik. Sehingga apabila pemilik tidak ada, maka tidak ada lagi yang dapat mengambil keputusan. Adanya kebijakan yang dilakukan secara rutin untuk menjaga ketersedian barang dengan melakukan stock opname. Kurangnya sistem kemananan dalam menjaga kekayaan dan catatan toko sehingga sistem pengendalian intern pada toko dinilai masih kurang efektif.
¿Quiénes somos en los juegos de estrategia? Un análisis de las posiciones encarnadas e imaginadas por los jugadores en Frostpunk
Authors: Moreno Azqueta Carlos
Published: October 2022

“¿Quiénes somos en el mundo del juego?” ha sido una pregunta habitual en los game studies. Diversos estudios al respecto han propuesto tipologías fenomenológicas de nuestra presencia en el mundo del juego, así como potenciales funciones de los avatares y procesos enunciativos que transforman la experiencia y el sentido del juego, todo esto acompañado de una dimensión de agencia de los jugadores para definir en sus propios términos su presencia virtual. Bajo la asunción de que el posicionamiento imaginado de los jugadores es relevante para entender las prácticas de juego y el sentido del texto videolúdico, este trabajo se propone analizar las referencias espontáneas a la posición virtual propia en un videojuego de estrategia sin avatar (Frostpunk), expresadas por varios jugadores voluntarios. Estas referencias se analizarán según la dimensión de cercanía-lejanía con la comunidad política del juego, los roles encarnados, la relación con los ciudadanos, la legitimidad política y gameplay ético.
