Relevance The paper proposes an original design of a high-voltage electromechanical two-spiral voltage source based on a magnetic accumulation generator (MAG) and a voltage multiplier with improved characteristics. In the multiplier, with the help of special switches, the addition of all voltages arising from the electrical explosion of conductors in separate inductive energy storage devices connected in parallel to the magnetic accumulation generator is carried out. A mathematical model and the results of mathematical modeling of the operation of the voltage source are presented, the calculated ratios will find application for practical use. In the course of the work, methods of the theory of electric circuits, magnetic field, elements of mathematical analysis and the theory of electrical oscillatory processes (beating, resonance, etc.) in complex circuits were used. As a result, a ratio is obtained that determines the maximum value of the beat frequency between two electrical circuits connected by a weak capacitive coupling, creating a magnetic accumulation generator with high microwave radiation and with the possibility of its regulation. The results of the work will be used in power engineering (an ice control unit, a shunt reactor to increase the power factor, etc.), mechanical engineering, medicine (cardiology), military equipment, etc. In the future, it is planned to use the obtained results of work in the direction of studying the use of a pulsed electromagnetic field for dewatering and desalting oil, which will lead to an increase in the efficiency of existing installations in practice.

Authors: Khan Nazia , Mhlanga Gugulethu
Published: December 2022

We herein present the treatment of an actinomycosis osteomyelitis case. A 71-year-old female with a dental history of multiple tooth extractions two years prior who subsequently developed chronic osteomyelitis. Previous treatment included 10 sessions of hyperbaric oxygen and pentoxifylline tocopherol protocol as well as debridement of the lesion that had resulted in a subsequent midline pathological fracture of the mandible. The fracture was treated by intra-bony wiring. The clinical extra-oral presentation was that of severe pain, recurrent swelling of the submandibular areas bilaterally and draining fistulae. Our treatment included antibiotic therapy: guided by Microscopy Culture and Sensitivity and a segmental mandibulectomy with the placement of a reconstruction plate. The outcome of the therapeutic management was successful. Histopathology results confirmed chronic osteomyelitis with bacterial colonies in keeping with actinomycosis. At the six-week post-operative appointment, the patient was healing well.

Published: December 2022

The establishment of hematological profiles of animals taken from their natural environment or kept in captivity has great importance in determining the health status and biology of these species. Pollution in the habitat of reptiles and the impact of various diseases can be determined by analyzing blood parameters. In this study, the clinical hematology (erythrocyte and leukocyte count, erythrocyte types, differential blood formula, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration) of three Nose-horned Vipers (Vipera ammodytes) captured from Vize (Kırklareli, Türkiye) were examined. We detected the frequency of nuclear abnormalities in this species for the first time. We also provide the first erythrometric measurements of Vipera ammodytes, and found that the erythrocyte sizes of this species were larger compared to other species in Viperidae. Knowledge of the general health status of animals is important in species conservation action plans and monitoring studies.
Inseguridad, violencia y actividad económica

Solo muy recientemente aparecen, en Colombia, estudios que procuran evaluar el significado económico de la inseguridad y la violencia. En ellos se establece que los efectos directos de la criminalidad común y del conflicto armado sobre la economía son de magnitud alarmantes, si bien la opinión pública no parece percatarse de ello. Por otra parte, un mapa del estado del conflicto armado muestra la notable expansión de la guerrilla, su fortalecimiento financiero y el desarrollo acelerado de grupos paramilitares independientes del poder del Estado y de la acción de las fuerzas armadas. Además, las condiciones de una solución política son imposibles bajo las circunstancias actuales.

Published: December 2022

Records of pressure variations on seismographs were historically considered unwanted noise; however, increased deployments of collocated seismic and acoustic instrumentation have driven recent efforts to use this effect induced by both wind and anthropogenic explosions to invert for near-surface Earth structure. These studies have been limited to shallow structure because the pressure signals have relatively short wavelengths (<∼300 m). However, the 2022 eruption of Hunga Tonga–Hunga Ha’apai (also called “Hunga”) volcano in Tonga generated rare, globally observed, high-amplitude infrasound signals with acoustic wavelengths of tens of kilometers. In this study, we examine the acoustic-to-seismic coupling generated by the Hunga eruption across 82 Global Seismographic Network (GSN) stations and show that ground motion amplitudes are related to upper (0 to ∼5 km) crust material properties. We find high (>0.8) correlations between pressure and vertical component ground motion at 83% of the stations, but only 30% of stations show this on the radial component, likely due to complex tilt effects. We use average elastic properties in the upper 5.2 km from the CRUST1.0 model to estimate vertical seismic/acoustic coupling coefficients (SV/A) across the GSN network and compare these to recorded observations. We exclude many island stations from these comparisons because the 1° resolution of the CRUST1.0 model places a water layer below these stations. Our simple modeling can predict observed SV/A within a factor of 2 for 94% of the 51 non-island GSN stations with high correlations between pressure and ground motion. These results indicate that analysis of acoustic-to-seismic coupling from the eruption could be used to place additional constraints on crustal structure models at stations with collocated seismic and pressure sensors. Ultimately, this could improve tomographic imaging models, which rely on methods that are sensitive to local structure.
Rupture dynamics of a planar fault in a 3D elastic medium: Rate- and slip-weakening friction
Authors: Fukuyama Eiichi , Madariaga Raúl
Published: December 2022

We propose a new boundary integral equation method (BIEM) to model the spontaneous propagation of rupture on a planar fault embedded in a homogeneous elastic medium. The BIEM formulation is very compact and fast in computation, so that we are able to study the effect of different slip- and rate-dependent friction laws on dynamic shear fault propagation. We simulated a spontaneous rupture by a sudden break of asperity under two friction laws, rate and/or slip weakening. We examined both long and circular asperities. The long asperity model corresponds to the 2D anti-plane or in-plane problem. The obtained result shows that slip-weakening friction is important at the crack tip, and rate-weakening friction plays an important role in the healing stage. If slip-weakening friction is strong stress drops gradually at the crack tip. On the other hand, if rate-weakening friction is strong stress drops abruptly, but it stops suddenly and sometimes stress recovers. This sudden stop of rupture produces a heterogeneous stress distribution, which will in turn produce aftershocks. Finally, we studied a realistic asperity model in which rupture starts from a small patch and then propagates with finite rupture speed. Depending on the asperity size healing can occur even without rate-weakening friction. This is due to very strong healing waves produced by the edges of the asperity.
Re-evaluation of the 1836 “Hayward fault” and the 1838 San Andreas fault earthquakes
Authors: Toppozada Tousson R. , Borchardt Glenn
Published: December 2022

Current seismic hazard models include two major earthquakes (M ∼ 7) in the San Francisco Bay area that are close in space and time: an 1836 event on the northern Hayward fault and an 1838 event on the peninsula section of the San Andreas fault. Analysis and interpretation of the available historical accounts indicate that the 1836 event occurred east of Monterey Bay, far from the Hayward fault, and was of M ∼ 6¼. Also, the 1838 event was not confined to the 60-km peninsula San Andreas as current models indicate. Instead, faulting probably extended from San Francisco to San Juan Bautista (∼ 140 km), indicating a significantly larger earthquake (M ∼ 7½) than previously thought.

Damaging effects of the 1836 earthquake were reported only from Santa Clara to Carmel, and no contemporary effects were reported to the north of Santa Clara or near the Hayward fault. The illusion of an “1836 Hayward earthquake” evolved from a newspaper reminiscence published following the 1868 Hayward earthquake, stating that the 1868 effects in the East Bay were similar to those of an 1836 event. The article describes various strong effects in the East Bay that differ completely from the effects recorded for the 1836 earthquake but are very similar to those documented for the major 1838 San Andreas earthquake that caused extensive damage on both sides of San Francisco Bay. Based on this and other evidence, we conclude that the reminiscence describes the destructive June 1838 effects, but it erroneously indicates the date as June 1836. There is no evidence for any major historical earthquakes in the San Francisco Bay area before the 1838 earthquake, back to the founding of Mission San Francisco Dolores in 1776.

During the 1838 San Andreas fault earthquake, the shaking intensity in Monterey was as strong as or stronger than during the great 1906 San Andreas fault earthquake. This suggests that the 1838 San Andreas fault rupture may have extended to San Juan Bautista as it did in 1906. Numerous probable aftershocks were felt in the area south of San Juan Bautista. These damaged Carmel and Santa Cruz in 1840, and Alisal, 16 km west of the San Andreas fault, in 1841. The northern end of the 1838 faulting was previously assumed to be 25 km south of San Francisco. However, Mission San Francisco Dolores was damaged in 1838 but not in 1906, suggesting that the 1838 faulting extended to San Francisco. Also, the 1838 aftershocks were felt in Oakland as frequently and violently as those following the major 1868 Hayward earthquake, suggesting that the 1838 faulting on the San Andreas extended to the latitude of Oakland.

The 1838 fault segment ruptured again 68 years later as part of the overlapping 1906 San Andreas fault rupture. This, and similar evidence from southern California, indicates that M ∼ 7½ San Andreas fault earthquakes can recur at intervals of 68 years or less when they are followed by M ∼ 8 earthquakes on overlapping segments of the fault.
Seismicity and stresses in the Brazilian passive margin
Authors: Assumpção Marcelo
Published: December 2022

Seismicity and stresses along the Brazilian continental margin show different patterns between the northeastern and southeastern regions. In the northeastern margin, earthquakes tend to occur onshore under a strike-slip regime with horizontal compression parallel to the northern coast line. In the southeastern margin, higher seismicity is observed offshore, in areas where the continental crust was highly extended during the South Atlantic rifting in the Mesozoic. Three new events in the southeast continental shelf are shown to have reverse-faulting mechanisms, from waveform modeling of short-period teleseismic P waves. Multiple depth phases (reflections from the top and bottom of the water layer and double reflections in the water layer) could be identified and better constrained the hypocenters to middle and upper crustal depths. In South America, models of intraplate stresses caused by plate boundary forces and spreading effects due to the continental/oceanic crustal transition indicate higher compressional stresses in the SE offshore area, as compared with the continental area, in agreement with the observed higher seismicity and reverse-faulting mechanisms. The combination of regional stresses, local flexural effects from thick sedimentary loads, and a presumably weaker crust from Mesozoic thinning explains the main patterns of seismicity in the northeastern and southeastern Brazilian margins.
Estimates of regional and local strong motions during the great 1923 Kanto, Japan, earthquake (Ms8.2). Part 1: Source estimation of a calibration event and modeling of wave propagation paths

Published: December 2022

This article is the first of a pair of articles that estimate regional and local strong motions from the 1923 Kanto, Japan, earthquake. This Ms 8.2 earthquake caused the most devastating damage in the metropolitan area in Tokyo history. In this article, we first calibrate wave propagation path effects with a moderate-sized modern event. This event, the Odawara earthquake of 5 August 1990 (M 5.1), is the first earthquake larger than M 5 in the last 60 years near the hypocenter of the 1923 Kanto earthquake. We estimate the source parameters based on a grid-search technique using body-waveform data bandpass filtered from 1 to 10 sec at four local stations, because accurate source parameters are critical for calibrating the propagation effects. We find that the Odawara earthquake had a depth of 15.3 km, a dip of 35°, a rake of 40°, a strike of 215°, a seismic moment of 3.3 × 1023 dyne-cm, a source duration of 0.65 sec, and a stress drop of 170 bars.

Next, we investigate the effects of the propagation paths to the local and regional stations where seismograms of the 1923 Kanto earthquake were recorded, by comparing recorded waveforms with synthetic seismograms built with the calibration event. Path-specific flat-layered velocity models are estimated along travel paths from the event to stations Hongo (epicentral distance R = 82 km) in Tokyo, Gifu (R = 213 km), and Sendai (R = 374 km) using forward modeling. In constructing the velocity model for the Gifu station, we use STS-1 broadband seismograms recorded at the nearby Inuyama station. Consequently, at periods greater than 3 sec, the velocity models for stations Hongo and Gifu can successfully reproduce both body waves and direct surface waves, and the velocity model for Sendai station can explain the predominant direct surface waves. In the companion article (Sato et al., 1998), these velocity models are used to examine the adequecy of the variable-slip rupture models of the 1923 Kanto earthquake (Wald and Somerville, 1995; Takeo and Kanamori, 1992) to explain recorded seismograms and also to simulate strong motions from that event.
Surface rupture associated with a 5.3-mbearthquake: The 5 April 1986 Cuzco earthquake and kinematics of the Chincheros-Quoricocha faults of the High Andes, Peru
Authors: Cabrera Justo , Sébrier Michel
Published: December 2022

The shallow, mb = 5.3, 1986 earthquake that affected the Cuzco region reactivated the 18-km-long Chincheros-Qoricocha faults in the central part of the Cuzco fault system. Although the event has a moderate magnitude, clear surface ruptures were observed to total 3 km in length, with maximum 10-cm normal displacements. Fault kinematics related to the earthquake, analyzed where the Qoricocha fault had a maximum surface fault displacement, is in agreement with roughly N-S extension. The normal fault mechanism proposed for this earthquake is compatible with the surface kinematic analysis. Seismic activity prior to the 1986 earthquake is deduced from analysis of Holocene scarps. Trench exposures give evidence for at least three fault displacements, suggesting an average recurrence interval of the order of a few thousand years for surface-rupturing seismic events. These fault reactivations, with vertical displacement ranging from 0.6 to 2 m, were related to seismic events of Mw magnitude probably ranging from 5.8 to 6.9. Structural analyses of Holocene faults indicate that the Chincheros-Qoricocha fault activity was related to roughly N-S-trending extension, characterized by a horizontal N-S-trending σ3 axis and a vertical σ1 axis. The N-S extensional tectonics that controlled the Holocene and 1986 Chincheros-Qoricocha fault activity are the typical deformational pattern of the Peruvian High Andes and seem to be in agreement with compensated high topography.
Distribution and Regulation of Fragile X Granules in the Spinal Cord
Authors:   , Mitchell Molly Elizabeth , Akins Michael R , Marenda Daniel
Published: December 2022

Axons are remarkably complex neuronal domains that comprise multiple morphologically and functionally diverse compartments. Whether establishing and maintaining these compartments requires that local protein synthesis is differentially regulated across axonal compartments, and how such regulation might differ among neuron types, is unclear. To address this, we examined axons in the postnatal mouse spinal cord for the presence of Fragile X Granules (FXGs), a class of exclusively axonal ribonucleoprotein particles. FXGs contain Fragile X related RNA-binding proteins FXR2P, FXR1P, and FMRP and associate with ribosomes and mRNA. In brain circuits, FXGs are present in specific axonal subsets and exhibit circuit-dependent RNA-binding protein and mRNA composition. However, whether FXGs are also found in spinal cord axons is unknown. Here, I used a combination of genetic, immunofluorescence, and quantitative colocalization approaches to show that specific subsets of axons in the rodent spinal cord contain FXGs. FXGs are found along the length of the spinal cord but are most abundant in cervical forelimb circuits. As in brain, spinal cord FXGs contain FMRP and associate with rRNA. In cervical circuits, FXGs are present in particular axonal subsets including A-fibers, IB4+ nonpeptidergic C-fibers, [alpha]-motor axons, ascending nociceptive fibers, and propriospinal interneuron axons. In axons that traverse the CNS and PNS, FXGs are enriched within CNS compartments. Analyses of large diameter axons revealed that FXGs localize close to the plasma membrane. Evaluation of Fmr1 null mice showed that, in dorsal root, FMRP regulates FXG abundance in IB4+ C-fibers, but not other examined axon populations. Together, these findings suggest that FXGs regulate local translation in specific axons in spinal circuits in response to signaling at the plasma membrane.
Immunomodulation with Methotrexate Improves Treatment Response to Pegloticase in Uncontrolled Gout
Authors: Peterson Jeff ,   Western Washington Arthritis Clinic, Bothell, WA, USA
Published: December 2022

The combination of methotrexate and pegloticase not only improves response rate by nearly double but also reduces infusion reactions by nearly eightfold. This is significant as a major drawback of using pegloticase monotherapy was the significant infusion reactions that made many practitioners unwilling to use the medication in patients with severe gout who may not have responded to conventional therapies. Those patients now have a chance to live a normal life free from gout.
Can I Prevent Developing a Rheumatic and Musculoskeletal Disease Through Lifestyle Changes? A Focus on Nutrition

Published: December 2022

Accumulating evidence suggests that nutrition can reduce the risk of rheumatic and musculoskeletal disease and especially rheumatoid arthritis (RA) development. This effect may be achieved either directly or indirectly through the consumption of anti-inflammatory nutrients or the reduction of comorbidities, respectively. A pro-inflammatory diet increases RA risk while the Mediterranean diet and oily fish consumption providing anti-inflammatory omega-3 fatty acids both reduce risk. High sugar and salt consumption is also associated with increased RA risk. Therefore, the Mediterranean diet supplemented with dietary omega-3 fatty acids is recommended for individuals genetically susceptible to RA.
The Emergence and Development of Pohang's Polity in the 1st to 3rd Centuries
Authors:   Korean Ancient Historical Society, Kim Daehwan
Published: December 2022

The wooden coffin tomb stage society seems to have formed a loose relationship by forming towns and villages in various districts, but it is believed that the Okseong-ri group and Seonggok-ri group grew up competing together. In Okseong-ri, a group of wooden tombs centered on large wooden tombs of the 3rd century can be said to be the emergence of central towns and villages in this area. Especially around the 3rd century, such integration occurred in various ways by region, and it is thought that the elites of each region grew up competing with each other for a while. In such a process, the Okseong-ri group played an important role in the Pohang area, and it is clear that this area was the center of the small country at that time, or the town center.

Authors: Cerejo Lucas Nakamura , Machado de Mello Bueno Laura
Published: December 2022

This article has the objective to characterize the focal group as a qualitative methodology research technique for approaching the territory, being a tool to produce the necessary data from the perspective of a representative group of participants with common characteristics. This methodological strategy was able to highlight the importance of the perspective of the population about complex themes, valuing different knowledge and readings of the territory, in addition to their participation in the role of agents capable of promoting change, even though it’s not usual in the field of Architecture and Urbanism. The research mainly focused on the vulnerable population in the city of Campinas, in relation to the diseases Dengue and COVID-19, based on primary data mapping in the period between March 2020 and September 2021. Reaching out to civil society entities, it was possible to organize focal groups to discuss their understanding and perception of the pandemic situation. Applying this methodology proved to be essential for the investigation of a complex and unexpected scenario, with the overlapping of diseases and the significant change in the quality of life for these populations, refering to aspects in their residences and their perception of the public management of the pandemic, also depending on the sensibility of the researchers for a coherent development of the discussions. Finally, the methodology proved to be conducive to create a relaxed and safe environment for participants to talk about their problems and reflect on the impacts of both diseases on their day by day.
Conferência Mensajes de los territorios y proyecto
Authors: Fernández Pablo Alfredo Ligrone
Published: December 2022

El tema propuesto gira en torno a tres asuntos principales: las urgencias sociales, las políticas públicas y el proyecto en sus múltiples escalas espaciales y temporales.Elegimos ser muy concisos en el título. El primer componente “mensajes de los territorios” nos vincula con el dueto Teoría y realidad; el segundo, “proyecto”, con el dueto Teoría y práctica. Si bien ambos forman parte de una misma reflexión, tanto para los investigadores como para los profesionales, históricamente se ha exacerbado el quehacer en desmedro de conocer la realidad. Tal es así que, aun en ámbitos teóricos especializados, se da por sentado que “teoría de la arquitectura” es, exclusivamente, teoría del proyecto o del diseño. Esta mirada nos retrotrae medio siglo con autores que marcaron un único rumbo, como lo fuera el influyente Enrico Tedeschi y su “Teoría de la Arquitectura” de la década de los setenta y numerosos otros que, hasta hoy, siguen en ese derrotero buscando el modo óptimo, ideal, de proyectar. ¡¿Nos hemos olvidado de la realidad?! ¡¿Nos hemos olvidado de la gente y de la naturaleza?! Seguramente no… Pero tal vez sí nos olvidamos de buscar denodadamente conocerla, entenderla, interpretarla y, por consiguiente, cambiar nuestro quehacer, nuestras herramientas de investigación, nuestros instrumentos de planificación, nuestro encare del proyecto de un tiempo a otro, de un territorio a otro, de un grupo social a otro. Ello permitiría mejor escuchar los mensajes.

To Walk the Same Road: Convivial Possibilities and Ethical Affordances in Borderlands Schooling
Authors: O'Connor Brendan
Published: December 2022

In this article, I explore how teachers and students in two distinct regions of the US-Mexico borderlands, southern Arizona and south Texas, treated social difference as an ethical affordance (Keane 2014) or a resource for moral stancetaking. Inspired by work in the anthropology of morality and ethnomethodological analyses of “accountable moral choice” (Heritage 1984, 76) in interaction, I examine how the salience of social difference can become an imaginative affordance for probing experiences of and possibilities for living with difference. When axes of social differentiation became relevant to ongoing interaction, participants used them to frame their own actions or others’ actions as morally admirable, justifiable, or questionable. At times, they did so in ways that foreclosed possibilities for conviviality; at other times, their “ordinary” ethical activity (Das 2012) suggested new possibilities for dealing with social difference in diverse contexts. The analysis testifies to the “internally riven” nature of the moral universe (Keane 2011, 173)—the different stances available to be taken up, even in relation to the same people and the same objects of evaluation—and underscores that conviviality is better viewed not as a lasting state of affairs, but as a provisional interactional achievement and a site of struggle and contradiction.

Published: December 2022

Human trafficking criminal act is, until now, a form of human slavery. Human trafficking is one of the worst treatments and a violation of human honor and dignity, and is automatically a violation of human rights. This paper aims at describing factors which cause child trafficking many occurring recently and the efforts to prevent child trafficking. This normative juridical research employs a statute approach and a case approach. The research finds that child victims of trafficking are trafficked for various forms of exploitation from sexual exploitation (organized prostitution), forced labor, slavery and other slavery practices. The efforts to prevent child trafficking are regulated through various laws and regulations, such as Law Number 35 of 2014 concerning the Amendment to Law Number 23 of 2002 concerning Child Protection. The factors to cause child trafficking are lack of awareness, poverty, culture, lack of education and weak law enforcement.
Induction of programmed cell death in lung cancer cells by secondary metabolites of Nocardia carnea UTMC 863 as soil actinomycetes
Authors: Moradi Gardeshi Tohid , Norbakhsh Rahil , Khaksari Soheila , Boroughani Zahra
Published: December 2022

Background: Apoptosis induction is one of the effective mechanisms in cancer therapy. So far, various natural sources have been identified for inducing apoptosis in cancer cells. This study proposed identifying promising active drug pharmacophores of soil actinomycetes with the capability of apoptosis induction in A549 cells, a human alveolar adenocarcinoma cell line.
Methods: The crude extract of Nocardia carnea UTMC 863 was obtained from UTBC (University of Tehran Biocompound Collection). After 48 hours of exposure, cell viability, gene expression, and apoptosis rate were determined using MTT, quantitative real-time-PCR, and flow cytometry.
Results: The MTT assay exhibited that the effective concentrations of UTMC863 and doxorubicin (positive control) were 24 µg/ml and 1 µM, respectively. UTMC 863 with a 24 µg/ml concentration and doxorubicin could induce apoptosis in the A549 cell line. Also, apoptosis-related gene expression increased in the UTMC863 group compared to the untreated group (p<0.01).
Conclusions: The crude extract of Nocardia carnea UTMC 863 can induce apoptosis in A549 cells, and it may be one of the promising pharmacophores for cancer therapy.
The Importance of Early Detection of Ovarian Cancer: Epidemiology and Risk Factors
Authors: Sharath Hardikar Navneetha
Published: December 2022

Background: Although not having a high incidence, ovarian cancer still leads to the most common cancer-related death among women diagnosed with gynecologic malignancies. The present study aims to highlight this disease’s epidemiology, risk factors, and the significance of developing improved early detection strategies.
Methods: Articles were accessed from PubMed and Google Scholar without a time limit. Full-text English studies that mentioned epidemiology and risk factors of ovarian cancer were included in this review.
Results: The highest incidence and mortality rates are observed in Central and Eastern Europe, while rates are relatively low in some parts of Asia and Africa. The risk factors for this disease include family history, hormonal factors, nutrition, diet, and physical activity. We also discussed some protective factors. There are no reliable screening methods for ovarian cancers. The most common diagnostic methods include a pelvic exam, a transvaginal ultrasound, and several imaging tests.
Conclusions: The mortality rate of ovarian cancer is gradually increasing; thus, preventative measures are required to reduce the lifetime risk of ovarian cancers and improve the mortality rate.

This study aimed to examine the occurrence of fear, anxiety and depressive symptoms associated with COVID-19, to assess influencing factors that lead to the development of these mental health conditions and to examine any changes in the mental health patterns of the society since the initial study a year ago in Sarajevo, Bosnia and Herzegovina.
Method: An anonymous online survey based on Fear of COVID-19 Scale (FCV-19S), General Anxiety Disorder-7 (GAD-7) and Patients Health Questionnaires (PHQs) was conducted in the general population of Sarajevo in Bosnia and Herzegovina.
Results: From 1096 subjects, 81.3% were females, 33.8% had a high school degree, 56.4% were married, 53.4% were engaged in intellectual labor, 42.3% experienced fear, 72.9% had anxiety symptoms and 70.3% had depressive symptoms during the COVID-19 pandemic and their mean age was 35.84 ± 10.86. Half (50.1%) of the subjects were COVID-19 positive and 63.8% had COVID-19 symptoms when responding to the questionnaire. Experiencing COVID-19 related fear (OR = 1.972) and having moderate to severe depressive symptoms (OR = 9.514) were associated with the development of mild to severe anxiety symptoms during the COVID-19 pandemic, which were in turn associated with the development of moderate to severe depressive symptoms (OR = 10.203) and COVID-19 related fear (OR = 2.140), respectively, thus creating a potential circulus vicious. COVID-19 positive subjects (OR = 1.454) were also more likely to develop mild to severe anxiety symptoms during the COVID-19 pandemic.
Conclusion: In conclusion, the prevalence of fear, anxiety symptoms and depressive symptoms rose dramatically since the beginning of the COVID-19 pandemic in Bosnia and Herzegovina. They were interconnected and were significantly associated with age, gender, marital status and COVID-19 status. Therefore, an urgent mental health intervention is needed for the prevention of mental health problems.

Objective: The aim is to determine the relationship between academic procrastination, depressive symptoms and suicidal ideation in students of the Faculty of Health Sciences.
Method: It was a non-experimental and cross-sectional study of correlational scope. The non-probabilistic convenience sample, made up of 578 participants between 16 and 30 years old (69% female), completed the Academic Procrastination Scale, the Positive and Negative Suicidal Ideation Inventory (PANSI) and the Beck Depression Inventory (BDI-II). Frequencies and percentages were estimated at a descriptive level, the partial correlation coefficient and multiple linear regression were utilized to examine the associations between academic procrastination and suicidal ideation.
Results: Subjects with a higher score of academic procrastination and BDI-II reported higher scores for suicidal ideation than those with a lower score (P < 0.01). A positive significant relationship was found between total academic procrastination and its subscales and suicidal ideation (P < 0.01). This correlation remained significant after controlling for depression (P < 0.05). Moreover, multiple linear regression revealed that academic procrastination, its subscales and depressive symptoms could explain about 20% of the total suicidal ideation in university students (R2 = 0.198).
Conclusion: Increased levels of academic procrastination increase suicidal ideation in college students during the pandemic. These results suggest the need to create interventions for the prevention of this problem in the fields of educational and public health.

Objective: This study was designed to compare object relations and anger control between MS patients and normal individuals.
Method: The present study was a cross-sectional case-control study with two groups: the case group (patients with MS) and the control group (normal controls without MS). 80 patients and 80 healthy individuals were selected according to the inclusion and exclusion criteria using a simple random sampling method. The research’s data collection tool was a threepart questionnaire consisting of demographic information, the Bell Object Relations and the Reality Testing Inventory (BORRTI) and the State-Trait Anger Expression Inventory 2 (STAXI-2). The data were analyzed by the SPSS software version 26 using descriptive and analytical statistics (stepwise regression).
Results: The results showed that in terms of object relations, there was no significant difference between the two groups except in alienation of relations (P = 0.035). The results also showed that in general, there was no statistically significant difference between the anger index of the group of MS patients and the normal controls. However, 12.8% of MS patients were significantly different in state of anger, trait anger and anger control compared to normal individuals. This difference was especially higher in angry temperament (P = 0.025) and the anger expression-in (P = 0.04).
Conclusion: Although patients with MS were not significantly different from healthy individuals in terms of intrapsychic and interpersonal functions in the context of object relations and anger management, it seems that more complex and multifaceted explanations lie in the results that need further research.

Objective: To determine the status of self-care performance of pregnant women in the prevention of COVID-19 disease and its relationship with perceived stress during the epidemic period of this disease.
Method: This cross-sectional study was performed on 228 pregnant women who referred to the health centers in Tabriz, Iran, for prenatal care. They were selected by cluster sampling. Data collection tools included questionnaires about Demographic-Social Characteristics, the Self-Care Performance Questionnaire and Cohen’s Perceived Stress Scale. Spearman correlation test was used to examine the correlation between self-care performance and perceived stress in bivariate and multivariate analyses. Also, multivariate linear regression was used, with control of demographic-social and obstetric characteristics as possible confounders.
Results: The median (25-75 percentiles) self-care performance score of participants was 0.71 (0.65-0.76), from the achievable range of 20-80, and its mean (± SD) perceived stress score was 25.5 (± 5.6), from the achievable range of 0- 56. The Spearman’s rank correlation test results showed a significant inverse correlation between perceived stress and self-care performance scores (r = -0.13; P = 0.041). According to multivariate linear regression test, the variables of selfcare performance, education, spouse's education and number of family members were the predictors of perceived stress in pregnant women during the COVID-19 epidemic.
Conclusion: According to the results of the present study, self-care performance of pregnant women in prevention of the COVID-19 disease was good and their stress was moderate. There was a significant inverse correlation between selfcare performance and perceived stress that could indicate the high value and importance of the fetus for the mother and her strict adherence to health protocols to prevent COVID-19, which also leads to calming and reduced perceived stress.

Published: December 2022

Objective: Perfectaionism is a common personality trait that can affect various aspects of life, especially sexual relationships. The purpose of this systematic review was to summarize the existing evidence for the relationship between perfectionism and sexual function in studies conducted in Iran and the world.
Method: A comprehensive search of databases such as Scopus, PubMed, Cochrane, Science Direct, ProQuest, PsychINFO, IranPsych, Irandoc, SID, and Google Scholar search engine was performed until December 2021 without a time limit. To find studies, we searched for the keywords perfectionism and sexual function in both Persian and English and combined these words with the AND operator. Studies that scored above 15 according to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) criteria were included. Data analysis was performed qualitatively.
Results: From the total of 878 articles found in databases, six articles met the inclusion criteria and had moderate quality. Reviewing studies corroborated that, notwithstanding the positive association between general/sexual perfectionism and sexual desire, specific dimensions such as socially prescribed perfectionism, partner-prescribed, and socially prescribed sexual perfectionism, have the utmost unfavorable effect on female sexual function, which means that a higher level of perfectionism ultimately decreases the rate of sexual function in women. In addition, studies suggested that by increasing sexual anxiety and distress levels, perfectionism deteriorates sexual function.
Conclusion: Perfectionism may cause a variety of problems regarding sexual function. However, to clarify the precise role of each dimension of perfectionism on different areas of sexual function, more research must be conducted in this area in various communities and on age groups other than females of reproductive ages.
