Authors: Deng Zhigang , Fan Xiwei , Chen Jian
Published: January 2023

Building height information is essential for many applications such as urban planning and population density estimation. The building shadow length varies according to seasons, which is shown as different digital number values in multi-temporal images. Thus, the bi-temporal satellite
remote sensing images of Sentinel-2 are used to estimate the buildings height in this study. An area of 15 km × 15 km in Beijing, China is taken as the study area. By preprocessing the data, the remaining pixels are split into two parts: 70% as the training data set and the rest as the
testing data set. Then, one classification model and three regression models are proposed with using Random Forest (RF) method. Based on the testing data, it shows that the accuracy rate of the classification model has reached 98.4% with the kappa coefficient of 0.93. And the regression models'
root-mean-square error (RMSE) is 0.61 floor for 1–6 floors group, 0.41 floor for 7–12 floor group, and 0.98 floor for above 12 floor group. The final RMSE is 1.62 floor with RF models. In general, this study shows the feasibility of using satellite mid-resolution optical image
to estimate the building height and provides an important reference for regional building height estimation in the future.

This paper presents the optimization of a 10 MW solar/wind/diesel power generation system with a battery energy storage system (BESS) for one feeder of the distribution system in Koh Samui, an island in southern Thailand.  The main objectives are to maximize the deployment of renewable energy-based power generation and to minimize the levelized cost of energy (LCOE).  A hybrid renewable energy-based power generation system, consisting of solar PV, wind turbine generators, diesel generator (DiG), bi-directional grid-tied charging inverter (CONV) and BESS, was simulated using HOMER Pro®. This study accessed the database of the National Aeronautics and Space Administration (NASA) for the Surface meteorology and Solar Energy (SSE) for the global solar radiation and temperature, along with the Modern-Era Retrospective analysis for Research and Applications (MERRA-2) wind database. The simulations show that Scenario 1 (PV/Wind/DiG/BESS/CONV) and Scenario 3 (PV/DiG/BESS/CONV) are the optimal configurations regarding the economic indicators (i.e. minimum net present costs (NPC) of 438 M$ and LCOE of 0.20 $/kWh) and the environmental indicators (i.e. lowest greenhouse gases (GHG) emission avoidances of 6,339 tonnes/year and highest renewable fraction (RF) of 89.4%). Furthermore, the sensitivity analysis illustrates that Scenario 3 offers the optimal system type with the largest annual energy production (AEP). Besides contributing to the body of knowledge of optimization methodologies for microgrid hybrid power systems, the outcome of this work will assist the regional energy practitioners and policy makers regarding optimal configurations of microgrid hybrid systems in the development of a Green Island concept for Koh Samui.
Mine void identification using Object-based Image Analysis (OBIA) of satellite imagery Sentinel 2 data

Published: January 2023

Open pit mining is an extensively-used method in Indonesian coal mining. This method is characterized by the formation of mine void at the end of life-of-mine (LOM) due to insufficient material to backfill the mine-out areas. Mine voids are legally accepted as one of mine closure options and categorized as “Reklamasi Bentuk Lain” - a miscellaneous reclamation option (Decree of Minister of Energy and Mineral Resources/KepMen ESDM No.1827, 2018), However, unmanageable voids will exert negative impacts. The identification and mapping of mine voids spatially are imperative to give stakeholders ample information to construct viable mine voids management and benefit all stakeholders. In this research, Sentinel 2 satellite image data is used for land monitoring so that void can be mapped based on land cover classification. The land cover classification was carried out based on the Object-based Image Analysis (OBIA) method. This method has a good level of accuracy, ranging from 86.1 to 96.4%. Based on the land cover classification, potential voids are analyzed based on their shape, where potential voids have elongation values of 0.2-1.0 and circularity of 0.1-0.8. In addition, potential voids are analyzed based on the location where they are found (referred to as the Mining License Area/WIUP data). In 2018 there were 40 potential voids inside WIUP and 5 potential voids outside WIUP, while in 2020, 62 potential voids inside WIUP and 8 potential voids outside WIUP were identified in the study area. The final result of potential mine void, i.e. mine void-1 could not further be distinguished between mine sumps, voids, or mine ponds without additional data and analysis. On the other hand, mine void-2 could not be further assigned as natural water bodies or mine void from illegal activities. Subsequent studies using more elaborated data, processes, and analysis are important, to enhance the accuracy of void mapping using satellite images.
Morphological characteristics of top soiling in the reclamation areas of post-coal mining at Kutai Kartanegara and Kutai Timur Regencies
Authors: Mulyadi Mulyadi , Makhrawie Makhrawie
Published: January 2023

This study aimed to obtain information about the impact of different morphological characteristics and genesis at some reclamation sites after coal-mining activities. Two coal sites were chosen as study areas, i.e. the Separi site, which is located in Kutai Kartanegara regency and the Bengalon site, located in Kutai Timur Regency. A descriptive research method was used to identify the morphological characteristics of reclamation sites at different times (chronosequence). The results showed that in-situ weathering, indicated by soil leaching caused by rainwater infiltration, led to the formation of the Ah horizon more than two years after the reclamation activity. The process of material removal and disposal (cutting, filling, transporting and levelling) from coal mining operations tends to accelerate the decomposition of parent soil material and promote the formation of pre-cambic horizons. The soils used (horizon A, B, and C) for the topsoil of the reclamation site were initially Typic Hapludults and Typic Dystropepts, although Typic Tropaquents and sandy parent materials were also used. Due to the impermeable layers of overburdening where water channels in the soil profile and deeper layers have not yet formed as human-made soil and landscape (artificial) cause rainwater to fail to infiltrate deeper layers so that with less heavy rain, the groundwater level will rise to the surface and the land will become waterlogged/flooded.
Existential threats to pastoralism in an arid environment: the fate of Gujii pastoralists in Southern Ethiopia

Published: January 2023

The pastoralists of Gujii have faced numerous risks, with their pastoralism system facing serious challenges. With the technically inconsistent and timely unmanaged interventions, several pastoral households are facing unreserved challenges. As a result, the future of pastoralists appears to be in great danger. The objective of this study is to investigate the ongoing challenges of Gujii pastoralism, as well as the fate of pastoralists in southern Ethiopia who are suffering from unrelenting drought. Ethiopian Meteorological Agency provided monthly rainfall and temperature data from 1986 to 2016. A household survey was conducted with 340 household heads randomly chosen from the study area to examine the challenges of the pastoralists have been facing. Moreover, a key informant interview and a focus group discussion were employed to collect qualitative data. Each watershed unit held one round of focus group discussions, with an average of 7-10 participants. The coefficient of variation (CV) was used to detect the temporal variability of seasonal rainfall and temperature. To detect trends, the Mann Kendall (MK) and Sen's slope estimator were used to determine the trends and magnitude of the change.  Political and tenure insecurity seriously affected the pastoral system in different ways. Autumn and spring had high variability in rainfall, with CV = 48.76% and 32.43%, respectively. Both winter and spring temperatures show a significant increase at (a = 0.1). Climate variability has made the already fragile pastoral households even more vulnerable. Pastoralist’s future would be difficult with all of these problems, and its resilience would be doubtful. As a result, in order to ensure the pastoral's long-term survivability, the government.

Authors: Matheus Rupa , Kantur Donatus , Salli Maria K
Published: January 2023

This study aimed to evaluate the effects of soil amendment and phosphorus fertilizer application techniques on the chemical properties of dry land Vertisols, P absorption efficiency by maize and maize yield. The study was conducted on farmer's land located in Noelbaki Village, Central Kupang District, Kupang Regency, East Nusa Tenggara, Indonesia. The study was conducted during two planting seasons, namely the rainy season 2020/2021 (PS-1) and the dry season 2021 (PS-2). The soil used in this experiment was included in the degraded Vertisols. This study used a split-plot design with three replications. The main plot was the type of organic soil-amendment material, and the subplot was the technique (dose and stage) of applying phosphorus fertilizer sourced from SP-36. The results showed that organic soil amendment and phosphorus fertilizer application techniques could improve soil chemical properties, P uptake, P absorption efficiency and maize yield in Vertisols until the second planting season. In the long term, the combination of maize stover biochar and the technique of applying phosphorus fertilizer (P3-T2) significantly increased the P uptake by 32.31 kg ha-1 (PS-1) and 31.23 kg ha-1 (PS-2), the P absorption efficiency by 28.65% (PS-1) and 27.75% (PS-2). The P3-T2 treatment gave maize yields of 6.92 t ha-1 (PS-1) and 6.92 t ha-1 (PS-2), which were higher than those of other treatments.

Authors: Rajah Nawin , Amran Azlan , Cheah Jeffrey
Published: January 2023

Social enterprise movement has emerged as a forceful social innovation paths to eliminate or address social problems. Aligned with the 11th Malaysia Plan and Transformasi Nasional 2050, Malaysia is committed to building a sustainable and equitable people-centric economy. To achieve the goal, the Malaysian government had set up Malaysian Global Innovation and Creativity Social Entrepreneurship (MaGIC) Unit in 2013, to propel the social enterprise sector and bring significant societal well-being to the disadvantaged groups. However, it is still at the nascent stage. As most of the social enterprises in Malaysia are still confronted with critical survival and performance challenges, it has become imperative for these entities to formulate strategies to enhance their resilience and performance. Hence, the main research objective is to examine the role of internal capabilities (i.e., management vulnerabilities and situation awareness) and external capabilities (i.e., training and financial support) influencing social enterprise performance in Malaysia. A mediating variable adaptive capacity was adopted to reflect the relationship between the predictors and the level of resilience of social enterprises in Malaysia. Due to the borderless nature of challenges and fluctuating environmental and unpredictable market condition, this research focuses on how Malaysian social enterprises would be able to adapt to the turbulence condition by resilience build, from the lens of Resource Dependence Theory and Resource Based View Theory. This study will employ a quantitative analysis to establish an explanatory model and more comprehensive understanding of this emerging field. The findings would advise the social enterprise's practitioners on their organisation’s strategic direction and offer a guiding model to the social enterprise investors, policymakers and future researchers.

The Health Effects of Video Games in Children and Adolescents
Authors: Alanko Daniel
Published: January 2023

Play has always been an essential part of childhood, but it looks different for modern children, who increasingly engage in virtual play. More than 90% of children older than 2 years play video games, and three-quarters of American households own a video game console. Children 8 to 17 years of age spend an average of 1.5 to 2 hours daily playing video games. Recent developments framed by decades of research have provided insight into how games influence children’s physical health, mental health, social behaviors, and cognitive development. Anticipatory guidance surrounding media use is often centered on screen time, but pediatricians should have some knowledge of the unique benefits and risks associated with this nearly ubiquitous activity. In light of the recent addition of gaming disorder to the International Classification of Diseases, 11th Revision, this review includes a discussion of the epidemiology, clinical features, and diagnosis of gaming disorder, including the use of existing screening tools. As games become more popular while ever-increasing in scope and complexity, this review aims to educate the modern pediatric provider about what is known, what is uncertain, and how to use this knowledge in the management of both healthy and unhealthy video gaming in children.
An initial investigation of improving acute care for hearing-impaired patients through the use of a transparent surgical mask
Authors: Bradbury Karen , Pines Rachyl
Published: January 2023

There is a general assumption that, in the hospital setting, standard surgical masks, unlike transparent masks, prevent effective communication with the hearing-impaired. This study investigates the experience of healthcare professionals (HPs) and hearing-impaired patients using a transparent surgical mask vs. a standard surgical mask in an acute care hospital. Our study design used a cross sectional, mixed-methods survey of 25 adult hearing-impaired patients/visitors and 36 HPs caring for them while wearing a transparent mask. The results demonstrated that 89% of staff and 76% of patients said the mask improved communication. This improvement was due to better ability to interpret nonverbal cues, which led to less need for repetition or volume increase. It was found that 69% of staff said the mask was comfortable and 81% were satisfied; 64% of patients liked being able to see facial expressions of the person wearing the mask; 72% of patients felt more connected to, and 76% understood the speech of, the person using the mask; and 80% of patients and 78% of staff preferred the transparent mask. The findings suggest that hospital staff/providers should use a mask with a clear window around the mouth and face while caring for hearing-impaired patients. This may improve patient satisfaction and prevent errors that are due to miscommunication.
‘The monster in the back seat’
Authors: Creten Silke , Heynderickx Priscilla , Dieltjens Sylvain
Published: January 2023

People living with dementia (PWDs) often experience stigma that is reinforced by negative representations of the condition in discourse. This paper addresses the lack of research into this stigma by analyzing the representation of the condition in naturally occurring texts of people in direct contact with PWDs. Two blogs from Flemish family caregivers and one blog from a Flemish health professional were selected based on word count and keyword relevance, and studied both quantitatively and qualitatively. For the quantitative analysis keywords, n-grams, and collocations were identified in 225 blog posts, using Sketch Engine. For the qualitative analysis, 26 blog posts were analyzed by categorizing conceptual metaphors according to their conceptual mappings. The quantitative analysis indicates that the health professional employs a different approach in reporting, compared to the family caregivers. The qualitative analysis results in five conceptual mappings: PWDs as living dead, PWDs as trees, dementia as concealment, dementia as an acting entity and dementia as an attack. The frequency of these mappings shows that the condition is being dissociated from the PWDs, and described with more negative metaphors than the PWDs themselves.

Objective: To raise the clinicians’ awareness of the rare adverse event of Immune Checkpoint Inhibitor (ICPis)-associated diabetes mellitus and peripheral nerve injury. Methods: We report a case of ICPis-associated diabetes and peripheral nerve injury caused by treatment with pablizumab in a 60-year-old male with lung cancer. Results: We describe a 60-year-old male who presented with “three more and one less” diabetic symptoms and severe numbness in the extremities after treatment with pabrolizumab. Based on the patient’s clinical symptoms, ancillary tests and corresponding follow-up findings, the patient was finally diagnosed with ICPis-associated type 1 diabetes and ICPis-associated peripheral nerve injury. The patient had poor compliance and was not given insulin glucose-lowering therapy at the beginning of the disease, and now the pancreatic islet function was severely impaired, the glycemic control was poor, and the numbness of the extremities did not improve significantly, which seriously affected the quality of life of the patient. Conclusion: ICPis-related diabetes mellitus and peripheral nerve injury is a relatively rare immune-related adverse reaction, which progresses rapidly and is more harmful, and therefore, should be taken seriously by doctors and patients in clinical work.
Personas y personajes en transición etno-sociolingüística en el ámbito románico. Algunos ejemplos de los siglos XVIII y XIX
Authors: Alén Garabato Carmen
Published: January 2023

A partir de finales del siglo XVIII, la instauración de la escolarización obligatoria y el aumento de la movilidad geográfica y social han contribuido a la difusión generalizada de las lenguas oficiales de los Estados, antes solo reservadas a algunos sectores privilegiados. En las comunidades que habían mantenido el uso de otra lengua, esto significa el fin del monolingüismo en un primer momento y luego la aceleración de las dinámicas que en algunos casos llevarán a la desaparición de las lenguas minorizadas.

El cambio de lengua implica un cambio de grupo y de clase social: una transgresión del poder simbólico, que no pasa desapercibida en la literatura de los siglos XVIII y XIX, en la que es frecuente encontrar personajes estereotipados que representan la transición etno-sociolingüística. Se trata de puestas en escena de la diglosia, productos de las ideologías lingüísticas, que no son (solo) simples divertimientos: los autores de las obras que comentaremos, en el ámbito románico, aprovechan el éxito popular de estos personajes para criticar o denunciar determinados comportamientos sociales o políticos.
Quan la lengua nacional desplaça la llengua materna a l’ensenyament: rastres de docència en català a començament del segle XIX
Authors: Ginebra Jordi
Published: January 2023

En aquest estudi es proporcionen dues menes de dades. En primer lloc, dades sobre textos escolars en català que s’imprimeixen entre 1800 i 1833. En segon lloc, dades de declaracions i testimoniatges sobre la perviviència del català com a llengua docent durant aquests anys. A continuació es planteja un debat per interpretar l’existència de les dades adduïdes: la continuïtat del català a l’escola malgrat la repressió practicada per les autoritats polítiques des de l’inici del segle XVIII. Primer s’emmarquen en el context de la situació històrica del segle, és a dir, de l’Antic Règim. Després en el context dels canvis polítics que tenen lloc a començament del segle XIX, amb la implantació del nou estat nacional contemporani. La conclusió és que els rastres de docència en català de començament del segle XIX són el testimoniatge final d’unes condicions històriques i polítiques que s’esvaeixen, ja que en la nova nació espanyola només és possible una llengua nacional: la llengua espanyola.
A propósito de la Gramática histórica de las lenguas castellana y catalana (1884), de Ignasi Ferrer i Carrió
Authors: Massanell i Messalles Mar
Published: January 2023

La historiografía lingüística señala como primera gramática histórica del catalán la Gramática de la lengua catalana, póstuma e inconclusa, de Tomàs Forteza, editada en 1915 con un prólogo de Antoni M. Alcover. A pesar de ello, en 1884 Ignasi Ferrer i Carrió, docente, articulista y autor de diversas obras gramaticales, había publicado una con el título de Gramática histórica de las lenguas castellana y catalana, que tiene la idiosincrasia de tratar en paralelo estas dos lenguas y que también para el castellano es la primera que se presenta como histórica, dos décadas antes que el Manual elemental de gramática histórica española, de Ramón Menéndez Pidal. En el presente artículo nos acercamos a dicha gramática de Ferrer i Carrió a través de lo que de ella se refleja en las publicaciones periódicas coetáneas y mediante los paratextos de la propia Gramática histórica de las lenguas castellana y catalana, una obra que, pese a no resultar muy lograda, presentó la novedad de ser la primera que reclamó para sí el calificativo de histórica.
Logonyms as a part of the linguistic landscape
Authors: Krško Jaromír
Published: January 2023

The paper deals with research into the linguistic landscape in the city of Banská Bystrica. The author focuses on logonyms as a part of the linguistic landscape; they are analysed in terms of formal aspects and the number of languages used. The existing onomastic research focused on logonymy in Polish onomastics in Slovakia abroad is also addressed in terms of the shift brought by the linguistic landscape research. The research of logonymy is more complex from the point of view of the linguistic landscape than from the point of view of onomastics, because the analysis of logonyms not only takes into account its onymic side, but also analyzes logonyms from the point of view of visual semiotics, pragmatics, semantic connotations acting on the recipient, etc.
A Novel Approach to Improve the Performance of the Database Storing Big Data with Time Information
Authors: TAŞYÜREK Murat
Published: January 2023

Big data is defined as data sets that are too large and/or complex to be processed by classical data processing methods. Big data analysis is essential because it enables more competent business movements, more efficient operations, and higher profits by using the data of institutions and organizations. However, large datasets are difficult to analyze because they are produced quickly, require large storage areas in computer systems, and the diversity of their data. In this study, a new approach using the denormalization method is proposed to accelerate the response time of the database in database systems where large volumes of data containing historical information are stored. Denormalization is defined as the process of adding rows or columns that are not needed to increase the reading performance of the database to the database system that has been normalized. In the proposed approach in this study, a large-volume dataset consisting of real spatial data belonging to Kayseri Metropolitan Municipality, containing temporal information and having approximately 96,000,000 row records, was used. In the proposed approach, the response time of the query is accelerated by recording the time information as numbers to increase the query performance of large volumes of data recorded in date format due to the temporal query process. The performance of the proposed method is compared with the performance of the normalization method using actual data on Microsoft SQL Server and Oracle database systems. The method proposed in the experimental evaluations shows that it works approximately eight times faster. In addition, the experimental results showed that the proposed method improves query performance more than the normalization-based method as the data size increases.

The study illustrates the utilization of software routines to implement a soft computing scheme in order to solve a closed loop disturbance rejection FOPID control system design problem for a target gain margin specification. Authors demonstrate that the complex design efforts, which involve a high level of mathematical knowledge, can be easily performed by using basic software routines when soft computing techniques are employed effectively in the computation processes. Illustrative design examples are shown to show effectiveness of the proposed design method.
Robust Modified Flower Pollination Algorithm for Power Quality Enhancement in an Autonomous 31-Level Cascaded H-Bridge Photovoltaic Inverter with Partial Shading Conditions
Authors: Ballav Sahu Jiban , Nayak Byamakesh , Choudhury Subhashree
Published: January 2023

The effect of global warming and the scarcity of fossil fuels has created an enormous problem in today’s era. To overcome such a problem, renewable energy sources, particularly solar energy, play a crucial role in meeting the developing need for power. However, the design of the Solar Photovoltaic (PV) system is interrupted by various factors such as the effect of temperature, isolation, aging, partial shading conditions, etc. Among all the factors mentioned, partial shading results in the significant diminution of power. To address this shading effect and enhance the flexibility of the PV system in terms of better utilization and energy extraction, a 31-Level Cascaded H-Bridge Multilevel Inverter (CHB-MLI) has been implemented to the autonomous PV system comprising of Maximum Power Point Tracking (MPPT) controller, boost converter and variable loads in MATLAB/Simulink architecture. To track maximum power from PV during varying irradiance and temperature and to further improve the system performance in terms of better convergence speed, an MPPT system with a Modified Flower Pollination Algorithm (MFPA) based PID controller has been proposed in this paper. To justify the suggested approach, the is-landed PV system is led to variation in irradiance and load. A detailed comparison of the proposed MFPA technique with classical control techniques has been meticulously discussed. The results obtained indicate that the suggested MFPA tuned PID with MLI outperforms the conventional methods in better system stability, reduced harmonics, and enhanced capacity to track maximum power from the PV system. In addition to this, the Total Harmonic Distortion (THD) using Fast Fourier Transform (FFT) has been found to verify IEEE-1547 power quality constraints. The values are found to be well within limits, thus justifying its real-time applications.

This research presents a method for forecasting the academic presentation of students in Portuguese as well as math subjects, and it is describing with the help of  33 attributes. Forecasting the educationalattainment of students is the most popular field of study in the modern period. Previous research has employed a variety of categorization algorithms to forecast student performance. Educational data mining is a topic that needs a lot of research to improve the precision of the classification technique and predict how well students will do in school. In this study, we made a method to predict how well a student will do that uses a mix of optimization techniques. BFO and ALO-based popular optimization techniques were applied to the data set. Python was used to process all the files and conduct a performance comparison analysis. In this study, we compared our model's performance with various existing baseline models and examined the accuracy with which the hybrid algorithm predicted the student data set. To verify the expected classification accuracy, a calculation was performed. The experiment's findings indicate that the BFO-ALO Based hybrid model, which, out of all the methods, with a 94.5 percent success rate, is the preferred choice.

Published: January 2023

Purpose: The primary aim of this study is to evaluate postural stability by using a static posturography in patients with early Parkinson’s disease (PD). Secondly, this paper addresses the need for illustrating the effect of dual-tasking on postural stability in early PD patients.

Materials and Methods: Twenty-nine early PD patients with maximum 5 years of disease duration were included in this study. The selected group had no clinical PI while their age- and sex-matched healthy controls were carried out. Neurological examination and mini-mental state examination (MMSE) were performed in all subjects. Unified Parkinson Disease Rating Scale (UPDRS) and modified Hoehn and Yahr (H&Y) scores were recorded in PD patients. Postural stability was assessed in all subjects on a static posturography platform under three different conditions: eyes open, eyes closed and a cognitive task of producing words with given letters.

Results: The mean age of the PD was 59.2±10.5 whereas the control groups mean age was 56.3±7.6 (p>0.05). The female-male ratio was 9/20 in the PD and 12/17 in the control group. There was no important difference between the two groups in terms of demographic characteristics. In the PD group, the mean UPDRS was 12.8±4.9. The patients were mostly receiving polytherapy.

Eye closure and cognitive task caused an increase in most sway parameters in both groups.

Conclusion: Early PD patients on medication, postural stability is preserved and cognitive dual-tasking does not affect postural stability in these patients in the early stage.

Purpose: The aim of this study was to compare retinal nerve layer thickness, central macula thickness and ganglion cell layer measurements using optical coherence tomography (OCT) between thyroid patients and age- and sex-matched healthy controls.

Materials and Methods: Eighty eyes of 80 patients in the thyroid patient group and 48 eyes of 48 patients in the control group were included in the study. After evaluating the exclusion criteria, visual acuity, anterior segment biomicroscopy, intraocular pressure, fundoscopy and spectral field optic coherence tomography (SF-OCT) imaging tests were performed on all patients included in the study. These data have been recorded. Central macular thickness (CMT), retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) measurements were evaluated by statistical methods for both groups.

Results: There was no statistically significant difference between the demographic data of the groups included in the study. IOP measurements were found to be statistically significantly higher in the patient group compared to the control group. CMT values were 258.2±16.1 µm in the patient group and 273.1±23.8 µm in the control group, and statistically significant differences were observed between the groups.

Conclusion: The findings supports that changes in the optic nerve and macula develop before vision loss in TO patients compared to the healthy control group. We can follow TO patients more objectively and reliably and make treatment planning more accurately by adding OCT, which is a noninvasive test, to our clinical practice, since structural changes develop before functional deterioration in TO patients.

Authors: DEMİRCİ Burak , COŞKUN Abuzer
Published: January 2023

Purpose: Childhood trauma is often caused by accidental or neglected falls. In this study, we aimed to evaluate demographic and clinical factors to determine the incidence of falls from height in children under two years old.

Materials and Methods: The study included 106 forensic cases who presented to the emergency department after falling from a height of one meter or more as a result of an accident or negligence between January 1, 2016 and December 31, 2021. According to the level of fall height, the cases were divided into two groups as below 3 meters and above. Clinical findings, hospitalization, and mortality status were used to group patients.

Results:Of the 106 cases included in the study, 59(55.7%) were male.The mean age of the patients was 12.89±6.80 months (p=0.002) and the mean height level was 3.67±2.85 m (p=0.001).The mean height of the Low and High groups was 1.78±0.71, 6.92±2.09 meters, respectively.Crainal fracture was present in 21(19.8%) patients in the high group and all traumatic parenchymal brain lesions except contusion were seen in the high group (p=0.001). Four (3.8 %) of the 9(8.5%) dead cases died in emergency department. The average height of emergency department fall victims was 9.75±2.63 meters (p=0.001).

Conclusion: Especially cases of falling from height under the age of two are common and are an important cause of morbidity and mortality. Fall height level is an important marker in terms of clinical and prognosis. Informing and educating caregivers and parents can prevent accidents and neglect in advance.
Diagnostic value of systemic immune-inflammation index and red cell distribution width-lymphocyte ratio in predicting troponin elevation in carbon monoxide poisoning
Authors: DUYAN Murat , VURAL Nafis
Published: January 2023

Purpose: The aim of our study was to assess the significant value of the systemic inflammatory index (SII) and red cell distribution width/lymphocyte ratio (RLR) in patients with carbon monoxide poisoning (COP).

Materials and Methods: Based on a retrospective cross-sectional study design, this study was conducted among patients 18 years and older who presented to the hospital's emergency department with COP. The patients were separated into troponin positive and negative groups as an outcome of serial troponin measurements. Receiver operating characteristic (ROC) analysis was used to determine the cut-off value of neutrophil/lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), RLR, and SII to predict troponin positivity.

Results: This study included 195 patients with CO exposure, 50 of whom had positive troponin tests. It was discovered that the diagnostic power of NLR, RLR, MLR, and SII was acceptable for identifying troponin positivity (AUC: 0.71-0.77). According to ROC curve comparisons, there was no diagnostic difference between these inflammatory biomarkers. Increased NLR, RLR, MLR, and SII were found to be independent predictors of troponin positivity after CO exposure (Odds ratio respectively: 8.65, 4.31, 7.24, 6.31).

Conclusion: SII and RLR, which are simple, inexpensive, and easily accessible parameters, are valuable in predicting troponin positivity in COP cases.

Published: January 2023

Üretral hemanjiomlar çocukluk çağında oldukça nadir olup genellikle anterior üretrada yerleşmekte ya da tüm üretrayı tutmaktadır. Çocuklarda 1977’den bu yana yaklaşık 20 kadar üretral hemanjiom bildirilmiş olup, bunların çoğu erkek olgu ve hemen hemen tamamı distal üretra yerleşimlidir. Özellikle erkeklerde posterior üretrayı tutan polipoid lezyonlar obstruktif üropati ya da enfeksiyon nedeni olabileceğinden ve rabdomyosarkom gibi diğer kitlesel lezyonlarla karışabileceğinden önem taşımaktadır1,2. Oldukça nadir olan proksimal üretra yerleşimli hemanjiom saptanan erkek çocuk olguyu burada sunmak istedik.

Purpose: The objective of this study was to determine the depression, anxiety, and stress levels of operating room workers during the COVID-19 pandemic.

Materials and Methods: The data were collected using the “Personal Information Form” and "Depression Anxiety Stress-21 (DASS-21)" scale. The personal information form consisted of eight questions including age, gender, profession, professional seniority, status of being diagnosed with COVID-19, being afraid of developing COVID-19, presence of chronic diseases and change in weight during the pandemic period. DASS-21 scale is a 4-point Likert type (never=0; always=3) scale and consists of seven questions with each predicting "depression, stress and anxiety dimensions".

Results: A total of 253 volunteers with 161 (63.6%) being female and 92 (36.4%) male were included in this observational screening study. Anxiety score of female participants (5.65±4.44) was found to be statistically significantly higher compared to the male participants (3.94±4.68). Depression (5.97±4.41), anxiety (5.48±4.53) and stress (6.94±4.59) scores were significantly higher in the participants who were afraid of developing COVID-19. Depression, anxiety and stress scores were significantly higher in the participants with chronic diseases than in those without chronic diseases.

Conclusion: The findings of our study indicate that the mean depression, anxiety and stress scores of the operating room personnel were mild.
