An Estimated Search and Matching Model of the Croatian Labor Market: Post-crisis Analysis
Authors:   Osaka University, Graduate School of Economics, Rkman Jelena
Published: December 2020

The paper specifies a simple search and matching model of the labor market and studies how well the model can describe aggregate Croatian labor market dynamics. The model developed is a discrete-time search and matching model with convex vacancy posting costs and two types of shocks: productivity and separation shocks. The model is estimated on unemployment and vacancy data during the period from 2012 to 2020 by using Bayesian methods. The model fits the data well and the estimation shows that productivity shocks are the main driving force of the fluctuations in the labor market, especially for the case of vacancies and output, while the separation shock process accounts for a large percentage of unemployment fluctuations.
Scaling the Necropolitical Anthropocene
Authors: Rife Tyler S.
Published: December 2020

In this essay, I demonstrate how the ecological concept of “scaling” carries potential to animate critical logics in the Anthropocene. I argue that scaling can expose unexpected linkages across space and time that help to denaturalize particular ecological formations as entangled, rather than separate. I demonstrate the critical ecological potential of scaling by performing it rhizomatically, weaving across scales of space and time while juxtaposing theoretical concepts with my experiences of life as a resident in the urban desert landscape of Phoenix, AZ. This ecology ultimately reveals how climate change acts as a complex necropolitic of the Anthropocene.
Contemporary Cli-Fi and Indigenous Futurisms
Authors: Pierrot Briggetta , Seymour Nicole
Published: December 2020

In this essay, we survey recent prominent works of climate fiction, or cli-fi, through the lens of Indigenous futurism, arguing that several of these works pointedly absent or even appropriate Indigenous perspectives and traditions. We conclude that this genre potentially works to justify settler colonialism.
SUPPLIER MANAGEMENT PRACTICE AND SERVICE QUALITY: CRITICAL REVIEW ON MEDIATING ROLE OF OUTSOURCING SERVICE PROVIDER CAPABILITIES
Authors: Conny Wang Man Wah , Tan Cheng Ling , Abdul Wahid Nabsiah
Published: December 2020

The increased demand for properties become part of the investment assets in Hong Kong. Facilities management practitioners need to face the challenges of proper maintenance and services to maintain the value of the property assets.  Based on the literature, facilities management companies can benefit from the share of market strength through their service providers. Hence, with the increasing demand for quality services, facilities management companies need to strive for survival and maintain their business power in the industry.  Nonetheless, literature shows that the service quality in facilities management is lacking.  Past research put less attention in conducting a critical review of research articles related to supplier management practice in the facilities management industry.  Additionally, the review identified a missing link of supplier management practice and service quality with the presence of outsourcing service provider capabilities as a mediator.  The critical review outcome assists the development of a framework to link the relationships among supplier management practice, outsourcing service provider capabilities and service quality.  This paper attempts to provide important supports for facilities management companies to capture the disposition of the company.  For having better leverage organizational context by exploiting relationships with outsourcing service providers, this paper extends Resource-based View Theory into outsourcing and service quality context.  Thus, this paper attempts to fill important gaps in the above contexts.  Finally, this paper suggests several recommendations for future study directions in the area of service quality in the facilities management industry.
Los retratos de la autora: el caso de Ángela Figuera Aymerich
Authors: Fernández-Menéndez Raquel
Published: December 2020

La proliferación en los últimos años de los estudios autoriales, de la mano de especialistas como Nathalie Heinich, Dominique Maingueueau, José-Luis Diaz o Jérôme Meizoz, ha posibilitado un nuevo análisis de la iconografía del escritor que permite comprenderla como uno de los elementos fundamentales que el régimen mediático pone a disposición del autor para garantizar su visibilidad. Sin embargo, a pesar del aumento de trabajos en torno a esta iconografía, aún no se ha avanzado en estudiar las tensiones entre género y autoría a través de los retratos de las escritoras. En este artículo se recurre a este nuevo paradigma crítico y a la teoría literaria feminista para analizar algunas de las fotografías de la poeta Ángela Figuera Aymerich (Bilbao 1902-Madrid 1984) como parte de un proceso de representación como mujer y autora en el campo cultural de los años cincuenta en España. El estudio de tres retratos representativos de su imagen mediática demuestra que el significado de cada imagen no es unívoco, sino que varía según el espacio editorial en el que el elemento fotográfico se localice (la prensa, los libros propios o las antologías poéticas) y de los discursos que rodean al paratexto.
Manuscritos e incunables en el entorno de los Reyes Católicos: el cancionero EM6
Authors: Martos Josep-Lluís
Published: December 2020

Este trabajo estudia los datos externos e internos del cancionero EM6, lo que supone una importante novedad, al haber recibido muy poca atención codicológica. Este es, sin embargo, el punto de partida para una metodología que combina las técnicas historiográficas con las filológicas: la llamada filología material. Así, se analizan las diferentes secciones de este cancionero con criterios ecdóticos y filológicos, de lo que se concluye lo siguiente: a) el estadio textual de las Coplas de la vita Christi es inmediatamente anterior a su versión impresa y debe singularizarse frente al testimonio del cancionero SA4a; b) las obras que se copian a continuación presentan diferencias de orden, de duplicidad y de mutilaciones respecto del impreso de Centenera de 1483, pero son indudablemente un codex descriptus de este; c) se delimita y confirma la materialidad de los tres impresos cosidos tras el cancionero de Íñigo de Mendoza, cuya datación coincide con el periodo de Isabel como reina de Portugal; d) se determina que, como los tres impresos incorporados a este manuscrito, la copia del Repertorio de los tiempos proviene del incunable impreso por Fadrique de Basilea en 1493 y no del producido por Juan de Burgos en 1495. Como conclusión principal, se enmarca este cancionero en el entorno de los Reyes Católicos y se atribuye a Martín de Mendieta, un hombre de cámara de la reina y de la princesa Isabel, de cuyos libros personales custodia una parte unos años después de su muerte.
Risks and Threats in Russian Regional Strategies
Authors:   Leontief Centre, Zhikharevich Boris
Published: December 2020

The article presents the results of the Russian experience of the inclusion of risks and threats in regional strategies of social and economic development. The official documents of 85 strategies were analyzed, the quality of risks and risk assessment was expertly assessed at a five-point scale. A ranked number of strategies was made taking into account an additional parameter, i.e. the number of references to the word “risk”. A list of the best strategies was made. They are the strategies of Sakhalin, Kurgan, Novosibirsk, Ivanovo regions, Zabaykalsky krai, and Republic of Crimea. The author notes that in most strategies of the Russian regions, attention is paid to risks and threats, but only in a third of strategies they are analyzed relatively well, and measures to deal with risks have been developed in no more than 10% of strategies. An abnormally large number of references to the word “risk” were identified when they are described in relation to all projects (Arkhangelsk region) or events (Zabaykalsky krai). The methodological problems associated with the analysis of risks and threats were systematized. They are a mixture of the concepts of problem, weakness, threat, risk, negative factor; lack of assessments of the likelihood and strength of the impact of risks; lack of description of measures to reduce the consequences of risks. The absence of a correlation between the quality of work with risks and threats and the regional resilience index characterizing the region’s resistance to economic and financial crises was found. The author notes that the regions that are aware of their vulnerability work better than other ones which mentioned threats and risks in their strategies, but this circumstance has little effect on their shock resistance against economic crises. The recommendations concerning the improvement of strategic planning are suggested. They are a thorough analysis of threats and weaknesses at the stage of a SWOT analysis, identification of a separate section on strategic risks, and development of an appropriate set of adaptive scenarios, creation of a regional risk management system.

Dr. R. considers in this article the question of: 1) in what cases it is necessary to operate with suppuration in the pelvis by the abdominal route, and besides, 2) in which of these cases is it possible to simultaneously cut out the uterus? The author excludes from his analysis abscesses of puerperal origin with an acute course, without participation in the process of the Fallopian tubes or ovaries, and is limited to examining purulent or cheese-like accumulations in the pelvis with or without the participation of the Fallopian tubes and ovaries.
Twisting of the uterus, especially of the pregnant uterus
Authors: Weber F.
Published: December 2020

One of the most common reasons for the rotation of the uterus around its axis is the old peri- and parametric exudates, which, wrinkling, can lead to significant displacements of the uterus. The twists, however, rarely reach a significant degree. The latter occurs when large tumors develop in close proximity to the uterus, most often ovarian cysts or subserous fibroids.

Testing an Empirical Green’s Function Method for Determining the Rupture Parameters of the 24 April 2014 Vancouver Island Earthquake
Authors: Paul Collin , Cassidy John F. , Dosso Stan E. , Hutchinson Jesse
Published: December 2020

In this article, we examine the 24 April 2014 Mw 6.4 earthquake offshore Vancouver Island using a surface-wave empirical Green’s function (EGF) deconvolution method and compare the results with SeaJade II double-difference aftershock locations. The 24 April event was well recorded and provides the first opportunity to evaluate the suitability of surface-wave EGF deconvolution to constrain rupture details for moderate-sized earthquakes in areas lacking dense seismic arrays. Our surface-wave EGF deconvolution results agree with the aftershock distribution and previously determined centroid moment tensor results. This agreement suggests that this technique is valid for events of this magnitude in a sparsely networked region. We used an Mw 5.3 earthquake about 21 km from the 24 April epicenter as the primary EGF source event and applied stacking to improve the signal-to-noise ratio. Our analysis used broadband seismic data from 105 regional and teleseismic stations. Given the small magnitudes of these events, an aftershock (Mw 4.8) was considered a secondary EGF source to verify key observations. The relative source time functions obtained from this study reveal an overall rupture direction of 143°±6°, extent of 28±2  km, and duration of 16.7±0.3  s. We also determined that the rupture occurred in multiple, distinct subevents, but the deconvolution was unable to determine the subevent parameters. Double-difference aftershock relocations using both onshore and offshore seismometers indicate a 32±2  km unilateral rupture with strike of 146°±2°. These independently determined rupture parameters agree with previously determined centroid moment tensor results with a nodal plane striking 150°±6°.

Published: December 2020

Aim: The objective of the present study was to compare the amplitude of the electromyographic (EMG) signal of the quadriceps muscle portions vastus medialis (VM), vastus lateralis (VL) and rectus femoris (RF) and the activation ratio (VM/VL, VM/RF and VL/RF) in protocols with different durations of concentric and eccentric muscular actions. Material and method: Twelve female volunteers performed the knee extensor exercise with two different protocols [1s for concentric muscle action and 5s for eccentric muscle action (1:5); 5s of concentric muscle action and 1s of eccentric muscle action (5:1)] and 3 sets of 6 repetitions, 180s of pause between each sets and a intensity of 50% of 1RM. The root mean square of the amplitude of the normalized EMG signal was calculated for each repetition in each series. Results: it was observed an increase in the activation of the VM and VL portions in equivalent repetitions of each series and for the VL portion, the 1: 5 protocol provided greater activation compared to the other protocol. No differences were found for muscles activation ratios VM/RF and VL/RF, being that for the VM/VL ratio there was only change at one repetition. Conclusion: The results suggest that the portions of the quadriceps muscle may present different EMG responses in similar protocols, but this fact may not interfere in the synergism between them. The reduced degrees of freedom of the knee extension exercise and the characteristics of the protocols adopted may be the elements that contributed to the limited alterations that occurred in the present study.
Clinical profile of ultrasonographic features and visual evoked potential changes in patients of ocular trauma with opaque media – A prospective study
Authors: Sajid Noorjahan , Sen Priyangee , Das Jayanta
Published: December 2020

To study the ultrasonographic features and VEP changes in eyes with ocular trauma having opaque media and the effect of such changes on the visual prognosis of these patients.

A prospective study of total 80 patients with ocular trauma attending the eye outpatient department in a tertiary care hospital was conducted. Their USG B scan and VEP examination was done in the Radiology department and Neuromedicine department respectively.

Blunt trauma was the cause of ocular injury in 60% of the patients, penetrating trauma in 25% and rest 15% had non-mechanical injury caused by acid burns, firecrackers.

Complications of ocular trauma e.g. cataract, vitreous haemorrhage and retinal detachment etc. could be detected to the extent of 93.12% accuracy by ultrasonography alone as compared to only 70.22% by clinical examination when both clinical examination and ultrasonography were combined together, 100% accuracy in diagnosis was reached. 96.25% of control eyes had a visual evoked potential latency, ranging between 81-110 msec and 88.75% had a VEP amplitude ranging from 6-15 µv. 66.25% of injured eyes had delayed visual evoked potential latency with the mean latency at 123 msec and about 41.25% had reduced VEP amplitude with the mean amplitude at 6.125 µv. Thus both the latency and amplitude were decreased significantly in injured eyes as compared to control eyes. Good post-treatment visual acuity was achieved in only 27.5% of patients.

: UBM is a very useful primary investigation to detect the posterior segment pathology in case of opaque media in traumatic eye. The VEP is affected in case of sight threatening findings. Thus VEP studies were more accurate than USG in predicting vision threatening ocular damage and the final visual outcome in this study.

Published: December 2020

BACKGROUND The prevalence of type 2 diabetes mellitus (T2DM) is increasing quickly all over the world. In spite of effective treatment guidelines for type 2 diabetes, in majority of the people, the disease is poorly controlled with existing therapies. Glycaemic control is considered as the most important step for prevention of organ damage and other complications of diabetes. A study on the prevalence and determinants of poor glycaemic control can assist in understanding the expanse of this problems and the ways to address it. We wanted to study the prevalence and determinants of poor glycaemic control among adult patients with type II diabetes mellitus attending a primary health care setting. METHODS The cross-sectional study was conducted in the outpatient department of NCD clinic in a Primary health centre of Kerala for a period of six months. Two hundred and fifty individuals diagnosed with Type II DM for a year were recruited as study participants. The study participants were interviewed using a semi-structured questionnaire. Adherence to medication was assessed using The Morisky Medication Adherence Scale. Anthropometric measurements and blood pressures were recorded. HbA1c and RBS was measured using semi quantitative technique. Any patient with an HbA1c of more than 7 was defined as having poor glycaemic control. RESULTS 64.4 % of the participants had poor glycaemic control. Poor adherence to medication, fewer visits to doctor, lack of diet modification, frequent junk food consumption, higher body mass index and lack of exercise were found to be significantly associated with poor glycaemic control. CONCLUSIONS A focused approach targeting these modifiable risk factors, especially in primary care setting, has the potential to bring about better glycaemic control which can prevent and minimize the occurrence of diabetes complications. KEYWORDS Poor Glycaemic Control, Uncontrolled Diabetes, Diabetes Mellitus, HbA1c, Diabetes Complications
Intravenous Ketamine for the Prevention of Post Anesthetic Shivering in Spinal Anesthesia: A Randomized Double-Blind Placebo-Controlled Trial
Authors: Sarshivi Farzad , Ghaderi Ebrahim , Sarshivi Arman , Shami Shoaleh , Nasseri Karim
Published: December 2020

Spinal anesthesia (SA) may impair thermoregulatory control, which may result in shivering, which is a potentially harassing complication. The aim of the current study was to evaluate the prophylactic effects of intravenous ketamine on the prevention of shivering in patients who underwent elective cesarean section (CSs) under SA. In this double-blind, randomized placebo controlled trial, a total of 90 parturients under SA using hyperbaric bupivacaine 12.5 mg were allocated in two groups to receive ketamine 0.3 mg/kg or 0.9% saline following delivery. After induction of SA, patients were observed for the incidence and intensity of shivering using a four-point scale. Shivering was observed in 24 patients (53.3%) in the saline group and 15 patients (33.3%) in the ketamine group. Median (quartiles 1 and 3) of the intensity of shivering was 1 (0-2) and 0 (0-2) in saline and ketamine groups, respectively. Time from spinal anesthesia to the beginning of shivering was 33.1±11.7 min in saline versus 41.6±20.7 min in the ketamine group. The incidence of nausea, vomiting, hypotension, and bradycardia was not different between the groups. A significantly higher incidence of nystagmus and sedation was observed in the ketamine group when compared with the saline group administration of low dose i.v. Ketamine (0.3 mg/kg) was effective in lowering shivering intensity during CSS under spinal anesthesia, though side effects such as nystagmus and sedation may restrict its effectiveness.

Published: December 2020

We aimed to determine the bone mineral status in patients with spondyloarthritis (SA), and to assess the impact of parameters associated with bone loss on bone mineral density (BMD). Seventy-five patients (62 men) with SA fulfilling the modified New York criteria were included in a cross-sectional study during one year. BMD was assessed in all patients using dual-energy X-ray absorptiometry. The patient’s average age was 36.8 years. Sixty-five patients (86.6%) had bone loss. The lumbar spine was the site most affected by osteoporosis (37%). Bone loss was significantly associated with low BMI, peripheral joint involvement, active disease (high ASDASESR and BASDAI), vitamin D insufficiency, elevated erythrocyte sedimentation rate (ESR) and c-reactive protein, as well as high BASRI, high BASMI, and with the use of csDMARDs or anti-TNF alpha therapy. The disease activity, biologic inflammation, low vitamin D level, peripheral joint involvement, and structural damage were the major factors that induce bone loss in SA patients. Multivariate analysis showed that only high ESR level (AOR 19.9, 95% CI) and peripheral arthritis (AOR 14.5, 95% IC) were independent risk factors of bone loss. Our study shows that bone loss was a multifactorial complication of SA.

Published: December 2020

Osteoporosis is defined as a reduction in bone density up to 2.5 standard deviations less than the maximum mean bone density in humans. It is estimated that 50% to 80% of the differences in the bone mass of the individuals are related to their genetic and heredity. The prevalence of osteoporosis is 6% in Iran, in which it is more than Japanese and less than in the United States. In this cross-sectional descriptive-analytical study, patients with a history of recurrent kidney stones (those who had referred to the stone clinic more than one time) undergoing bone density measurement using the DEXA method to determine the presence or absence of osteoporosis (Reduction of bone density up to 2.5 standard deviations less than the maximum mean bone density) were enrolled. Exclusion criteria were patients with metabolic diseases, corticosteroid intake, renal failure, hyperparathyroidism, and age >60 years. According to the results of this study, there were 61 patients with a history of recurrent kidney stones, which 34 of them (55.74%) were male and 27 (44.26%) were female; the mean age was 42.41±9.8 years (ranging from 18 to 60 years). Evaluation of frequency distribution of patients showed that 18% of patients had osteoporosis. In this study, 52.5% of patients were without osteoporosis and osteopenia. It should be noted that 29.5% of patients had only osteopenia. The frequency distribution of osteoporosis in patients with a history of recurrent kidney stones by gender showed that four males (36.4%) and seven females (63.6%) had osteoporosis. There was no significant relationship between gender and osteoporosis in patients with a history of recurrent kidney stones (P=0.153). There was also no significant relationship between gender and osteopenia in these patients (P=0.380). There was no significant relationship between age and osteoporosis in patients with a history of recurrent kidney stones (P=0.203). There was no significant relationship between BMI and osteoporosis in patients with a history of recurrent kidney stones (P=0.344). There was no significant relationship between osteoporosis with age and BMI in patients with a history of recurrent kidney stones, and the highest percentage of osteoporosis was in the spine region, which consisted of 8.2% of all patients. There was no significant relationship between osteopenia with gender and BMI in patients with a history of recurrent kidney stones, but there was a significant relationship between age and osteopenia in patients with recurrent kidney stones.

Published: December 2020

Background: Headache is among the most common disabling neurologic disorders. We measured quality of life in chronic migraine (CM) and episodic migraine (EM), stratified by medication overuse headache (MOH) and presence of aura.
Methods: In this observational study, conducted from January 2016 to December 2018, adult patients referred to the tertiary headache clinic of Sina Hospital in Tehran, Iran, who met International Classification of Headache Disorders,
3rd Edition-beta (ICHD-3 β) criteria for migraine were classified to EM and CM subtyped based on presence of aura and MOH. Validated Farsi versions of Migraine Disability Assessment Scale (MIDAS) and 6-item Headache Impact Test (HIT-6) questionnaires were used.
Results: A total of 2454 patients (1907 women) were enrolled from which 1261 (51.4%) patients had EM and 1193 (48.6%) had CM, while 908 subjects (37.0%) had MOH, of whom 890 (98.0%) had CM. Median scores of MIDAS and HIT-6 were significantly higher in patients with CM compared to EM sufferers. Chronic migraineurs with MOH had a significantly higher median score of MIDAS and HIT-6 compared to patients with non-MOH CM. Also, there was a moderate positive correlation between MIDAS (disability) and HIT-6 scores (impact on patients’ life) and a moderate correlation between HIT-6 and pain severity.
Conclusion: The results of this study confirm that CM and MOH are associated with a higher headache-related disability and impact on life compared to EM. Therefore, treatment goals in prevention of MOH and migraine transformation warrant higher quality of life in patients with migraine.

Published: December 2020

The potential role of microRNAs (miRNA) as therapeutic molecules has moved them from basic research to the field of cancer therapy. High expression of miR-93 and low expression of miR-34a have previously been indicated in prostate cancer (PC), which is the second leading cause of cancer-related death in men. Androgen receptor (AR) and prostate-specific antigen (PSA) play key roles in the initiation and progression of this cancer. Therefore, this study aimed to investigate the effects of the transfection and co-transfection of miR-34a mimic and miR-93 inhibitor with or without epigallocatechin-3-gallate (EGCG) on prostate cancer cell line and also to evaluate their effects on the expression of AR, PSA.
Human lymph node carcinoma of the prostate (LNCaP) cells were treated with miR-34a mimic or/and miR-93 inhibitor with or without EGCG. Gene or protein expressions were assessed by real-time PCR or western blotting of lysates.
The transfection with miR-34a mimics significantly reduced the mRNA expression of AR (p=0.0016), and PSA (p=0.038) compared to the control. Also, the miR-93 inhibitor led to a decrease in the mRNA expression of AR (p=0.0057) and PSA (p>0.05) compared to the control group. Furthermore, the co-transfection, along with EGCG, caused more decrease in both the AR (p<0.001) and the PSA (p=0.003) expression compared with the co-transfection without EGCG.
Our study indicates that the reduced expression of AR and PSA in PC cells followed by treatment with miR-34a mimic and miR-93 inhibitor and their combination with EGCG as a natural substance may be a promising therapeutic way for controlling the growth of these malignant cells.

The presence of ambient particulate matter (PM) poses more dangers to human health than that of other common air pollutants such as Carbon dioxide (Co2) and ozone.  Epidemiologic studies show a direct correlation between PM and the risk of respiratory and cardiovascular diseases. The immune system seems to play a critical role in the process of these diseases. The main goal of this study was to investigate the effect of Tehran particulate matter in two aerodynamic diameters (PM2.5 and PM10) on alveolar macrophages (AM) from C57/BL6 mice.
To evaluate the inflammatory effects of PMs, cultured alveolar, and peritoneal macrophages were treated with PM2.5 & PM10 (concentrations of 5 µg/mL and 10 µg/mL). Tumor necrosis factor-alpha (TNF-α) and IL-10 (representatives of inflammatory and anti-inflammatory cytokines, respectively) were assessed in the culture supernatant by ELISA. Expression of arginase and inducible nitric oxide synthase (iNOS) genes was carried out by quantitative real-time PCR. Different functional types of cultured alveolar macrophages (M1, M2) were also determined in this study.
Our results suggest that PM2.5 induces M1 inflammatory phenotype in comparison with PM10. We found Also, an increase in TNF-α and M1-related gene expression (iNOS), as well as a decrease in both IL-10 and M2 phenotype genes (Arginase). Moreover, a reduction in phagocytic capacity and increased apoptosis function of macrophage cells were detected.
PM2.5 as a major component in hydrocarbons has a considerable effect on polarizing the alveolar macrophages to an inflammatory phenotype and eliciting lung inflammation in mice.

Asthma is the most common chronic inflammatory respiratory disorder in children. This study was designed to assess the prevalence of asthma in 13-14-year-old adolescents in Karaj, Alborz province in Iran, using the international study of asthma and allergies in childhood (ISAAC) questionnaire. 
Totally 950 adolescents attending 40 schools located in 4 regions of Karaj city were enrolled in the survey. The Persian version of the ISAAC questionnaire was filled by 13-14-year-old students. Multi-stage clustered random sampling was used to divide the city of Karaj into four educational districts.
Ever wheezing was reported in 22% of the individuals; 10.52% claimed to have wheeze in the last 12 months and 22.73% had during or after exercise. The experience of wheezing in the last 12 months was more prevalent among males (11.73% vs. 9.38%; p<0.05). However, having a history of asthma was higher among males (7.55% vs. 3.47%; p<0.05). History of hospitalization (60.8%), family history of asthma (49.4%), and history of food allergy (42.3%) were found to be the most frequent characteristics significantly associated with" ever wheezing" (p<0.05).
The prevalence of wheezing in the last 12 months, as a major index of current asthma, was 10% which was close to the national average. However, nocturnal cough and exercise-induced wheezing were higher in Karaj compared to other cities of Iran; which could be related to the high level of air pollution in this industrial area.

Nurses face several challenges in providing care for patients with coronavirus disease in 2019 (COVID-19). The study aimed to explain the nurses' perception of ethical challenges in this regard. The qualitative study was carried out using a content analysis method. Individual and semi-structured interviews were conducted with 24 nurses. Inductive content analysis was used to categorize the data. Nurses' narratives indicated that ethical challenges in caring for patients with COVID-19 included threats to professional values ​​and the absence of a holistic COVID-19 care approach. The first category was subcategorized into the risk of declining quality of patient care and a stigmatized public image about COVID-19 care. The second category was divided into poor spiritual care, poor compassionate care, and lack of family-centered care. Health care managers must develop protocols for nurses that address these issues to alleviate the ethical challenges of COVID-19 care.

With the aim of improving the quality and expanding the functions of digital terrestrial television broadcasting services, we have been developing an advanced transmission system that inherits key features of the current Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) system, which employs hierarchical transmission based on frequency division multiplexing (FDM) and a segment structure. The advanced ISDB-T system has a new signal frame structure that enables bandwidth to be flexibly allocated to multiple services for different reception scenarios, such as fixed reception and mobile reception, compared with ISDB-T. By introducing transmission technologies such as the latest forward error correction and modulation scheme, this specification has high spectral efficiency and transmission robustness, i.e., the transmission capacity increases by about 10 Mbps for the same required carrier to noise ratio (CNR) in comparison with the current ISDB-T system, or the required CNR can be reduced by about 7 dB for the same transmission capacity. We describe the channel coding scheme and evaluated the performance of bit-interleaved coded modulation (BICM) in simulations. This paper provides a BICM selection guideline based on the simulation results for fixed reception scenarios toward the practical application of advanced ISDB-T.
