Published: February 2021

Space influences our cognitive-emotional state. In teaching spaces, with a considerable effect on performance. Many design variables are involved. Among them, geometry has been traditionally less explored despite its usual prominence in design, due to the complexity of its modification in existing physical classrooms. However, today this can be addressed through the use of virtual reality. This was the objective of the present study: to contribute to the study of the cognitive effect of different geometry parameters applied in a university classroom. It was tackled through a laboratory field study carried out with 80 university students. The geometry variable was studied through two parameters: ceiling heigh (3 settings) and width (3 settings) of the university classroom. The 9 combinations were implemented in a virtual reality. The cognitive effect was explored through memory and attention performances. Both of them, quantified through auditory psychological tasks: the former, using a list of words to memorize; and the latter, using a computer program to measure reaction times and errors. Analyses indicate that memory and attention can be affected by some of the geometry parameters. This suggests that they may be especially relevant in the design of university classrooms, which is of interest to the different agents involved in the university classroom project and design.

The serious situation caused by the coronavirus has forced Authorities to take drastic decisions that have affected the normal functioning of the entire society. One of the most impactful measures taken has been the self-discipline of the social distancing as the entire society has been obliged to stay at home. At the education level, restrictions ordered by the Authorities have limited the access to all professors and students at the academic centers. In Spain, the state of alarm decreed by the Government has affected the entire Academic course and therefore, in order to be able to preserve the public service, the Polytechnic University of Valencia, in just a week, has been asked to revise the entire programs and settle on-line courses for more than 35.000 students in multiples disciplines. Within this framework, a methodology has been developed for the implementation of on-line learning courses in a period of crisis within a short time. On-line learning has been demonstrated to be effective as face-to-face education, becoming one of the most popular higher education alternatives. However, students engaged in on-line classes result to be less engaged in collaborative learning, student-faculty interactions, and discussions with their classmates if compared to the traditional system. In this context, the barriers of on-line teaching classes have been investigated and tools to overcome them have been proposed. Finally, a real application to the Polytechnic University of Valencia is presented.

Published: February 2021

Microgrids are a group of loads and distributed power generation sources acting as a single entity to provide power to the user or the grid. Since a Microgrid is a system of systems, this leads to an operability problem for local management and an interoperability problem for remote management. Operability and interoperability problems are solved by Data Acquisition and Control Systems (SCADA). There are several commercial platforms for the development of SCADA systems, being most of the time very expensive for the average user and even many universities. Therefore, this paper presents the design and implementation of a SCADA Web based on open-source software for experimental microgrids to allow the management of Microgrids remotely through the web. The Web-based SCADA system was developed for the Renewable Energy Laboratory (LabDER) of the Universitat Politècnica de València. An OMRON CPU CJ2M PLC was linked to a remote MYSQL database. A user interface was programmed using JAVA, and PHP languages perform operations and take data for the web-based SCADA system. The implemented SCADA system allowed monitoring and limited control of the LabdDER microgrid remotely, showing it to be an effective solution for Microgrids remote management.

Authors: Bathla Manish , Pandey Apurva , Chandok Tanujveer S , Sahoonja Chahat
Published: February 2021

Background

Cancer can have a deleterious impact on the well-being of a patient and can affect the mental health. Cancer treatment is influenced by anxiety and depression and thereby recovery, quality of life, and survival may get hampered. Depression is the most common psychiatric syndrome that has received the most attention in individuals with cancer. It has an intense impact on lives of patients and it continues to be underdiagnosed and inadequately treated. Depression most commonly coexists with other syndromes such as panic disorder, generalized anxiety disorder, and post-traumatic stress disorder. Cancer is threatening and understandably many patients get anxious in response to that threat and anxiety appears to increase as the illness progresses. Depression and anxiety have impact on morbidity and mortality leading to worsening of quality of life. In patients with cancer on treatment, there is a greater degree of association between anxiety and depression with worsening of quality of life. In this study, we assessed prevalence of depression, anxiety, and the quality of life in patients undergoing cancer treatment. We tried to find out the correlation between prevalence of depression and anxiety. We also looked at the quality of life in patients undergoing cancer treatment.

Materials and methods

Our study was conducted on 50 patients who were undergoing cancer treatment. We used Hamilton depression rating (HAM-D) and Hamilton anxiety rating (HAM-A) scales, respectively, to assess the symptoms of depression and anxiety. The quality of life was assessed using quality of life-10 (QOL-10) questionnaire.

Results

In this study among subjects on chemotherapy, 46.7% had mild depression, 30% had moderate depression, 16.7% had severe depression, and 6.7% had very severe depression. Among subjects on radiotherapy, 53.3% had mild depression, 13.3% had moderate depression, 33.3% had severe depression, and 0% had very severe depression. Among subjects on chemotherapy along with radiotherapy, 20% had mild depression, 40% had moderate depression, 40% had severe depression, and 0% had very severe depression. In this study, 60% had mild anxiety, 38% had mild to moderate anxiety, and 2% had moderate to severe anxiety. Among those on chemotherapy, 66.7% had mild anxiety; among those on radiotherapy, 53.3% had mild anxiety; and among those on chemotherapy + radiotherapy, 60% had mild to moderate anxiety. In this study, there was positive correlation between HAM-A and HAM-D scores, that is, with an increase in HAM-A score, there was an increase in HAM-D score and vice versa.

Conclusion

In our study, patients with cancer had higher prevalence of anxiety and depression. Anxiety and depression often lead to poor quality of life.

Benign Cystadenofibroma Masquerading Malignant Tumor
Authors: Dubey Sunita , Kaushal Aayushi , Pavithra Haradanahalli N
Published: February 2021

Introduction

Cystadenofibroma of the ovary is a rare benign epithelial tumor of the ovary that impersonates with malignant features like solid nodule and papillae on imaging as well on gross examination of the specimen.

Case description

A 20-year-old unmarried girl visited our outpatient department with a complaint of pain in the lower abdomen for the last 1 year. Transabdominal ultrasonography revealed a well-defined complex cyst of about 9.4 × 7.4 cm size with a small echogenic nodule of 1.74 × 0.8 cm involving the left ovary. On color Doppler, there was an absence of increased internal vascularity. The right ovary was normal. CA 125 was within normal limits. She underwent laparoscopy, multiple solid papillae were seen after removal of a cyst, left salpingo-oophorectomy was done due to suspicion of malignancy. However, the final histopathology report revealed benign cystadenofibroma of the ovary.

Conclusion

Although there are no confirmatory imaging diagnostic tests to differentiate benign cystadenofibroma from malignant pathology, however, absent blood flow is significantly associated with the benign nature of ovarian cystadenofibromas despite solid nodule and papillae within it. An intraoperative frozen section may help in diagnosis and prevent extensive surgery in patients.

Gender differences in completed suicidal hangings from 2013 to 2018 in Muğla, Turkey
Authors: Goceoglu Umit Unuvar , Balci Yasemin
Published: February 2021

BACKGROUND:

Hanging is the most preferred among suicide methods. Although methods vary based on age groups and social and cultural conditions, many studies have reported it as the most common suicide method in Turkey.

OBJECTIVE:

Assess autopsy findings of suicidal hangings according to gender differences.

DESIGN:

Retrospective, cross-sectional.

SETTING:

Local morgue.

SUBJECTS AND METHODS:

The autopsy reports of hanging autopsies between 2013-2018. Data was retrospectively collected from autopsy reports. Sociodemographic features, reasons, suicide notes, the news media, and macroscopic autopsy findings were evaluated. Findings were statistically compared by gender.

MAIN OUTCOME MEASURE:

Gender differences in autopsy findings.

SAMPLE SIZE AND CHARACTERISTICS:

175 autopsy reports of suicide by hanging.

RESULTS:

Among 2534 autopsies, 175 (6.9%) cases involved hanging. Most (76%, n=133) were males; the median (interquartile range) age was 42.0 (29.5), the male/female ratio was 3:1. Suicide notes were found in 42 cases; 81 (24%) were from men. The most common reason for suicide was a mental illness (n=51, 29.2%), followed by family problems (n=26, 14.9%), but the cause was unknown in 42 cases (24.0%). More than half of the events were covered in the news media (58.9%). Rope was most commonly used with women preferring a softer material. Men were more frequently single than women. Men were more frequently single and not actively working than women (
P
=.026 and
P
≤.001, respectively). The incidence of atypical hanging was higher for males than females (
P
<.05).

CONCLUSION:

The findings showed that there were some statistically significant differences in socioeconomic and mental health factors between men and women in hanging suicide. This study may serve as the basis for more comprehensive studies to investigate the causes of suicide.

LIMITATIONS:

Single-center, retrospective.

CONFLICT OF INTEREST:

None.
Traumatic dental injuries in special health care needs children and association with obesity
Authors: Basha Sakeenabi , Mohamed Roshan Noor , Al-Thomali Yousef , Ashour Amal Adnan , Zahrani Fatma Salem Al , Almutair Nada Eid
Published: February 2021

BACKGROUND:

Special needs children are at a higher risk of dental trauma because of neurological, physical, mental, and behavioral impairments. They are also at higher risk of developing obesity due to the side effects of medication.

OBJECTIVE:

Assess the association between traumatic dental injuries (TDIs) and obesity in children with special health care needs.

DESIGN:

Analytical cross-sectional study.

SETTING:

Schools for special needs children.

STUDY POPULATION AND METHODS:

Special needs children with a diagnosis of TDI according to the Andreasen criteria were included in the study. Data on the disability status were obtained from a national demographic survey in 2016. Demographic and dental variables were measured for analysis. Multivariable logistic regression was used to analyse any relationship between TDI prevalence and obesity.

MAIN OUTCOME MEASURE:

Relationship of body mass index (BMI) to TDI prevalence.

SAMPLE SIZE:

350 (131 boys and 219 girls) special needs children with a median (interquartile range) age of 12.0 (2.0) years.

RESULTS:

Eighty-one (23.1%) children presented with TDIs. The mean (standard deviation) BMI for the entire study population was 24.7 (7.8). Children with obesity had a 30.3% TDI prevalence compared normal-weight children (20.6%) (
P
=.035), but BMI category was not statistically significant in the regression analysis (
P
=.541), which showed that children with an overjet of >3 mm were 4.82 times (CI: 2.55–9.09,
P
=.001) more likely to have TDI than children with an overjet of ≤3 mm. Those with inadequate lip coverage were 2.85 times (CI: 1.49–5.44,
P
=.002) more likely to have TDI. Children with cerebral palsy were 3.18 times (CI: 1.89–11.32,
P
=.024) more likely to have TDI than children with other disabilities.

CONCLUSION:

The study showed a significant association between TDI prevalence and increased overjet, inadequate lip coverage, and cerebral palsy. The prevalence of TDI among obese special needs children was statistically significant according to bivariate analysis, but not in a multivariate analysis that adjusted for other variables.

LIMITATIONS:

Causal relationship cannot be established with cross-sectional study.

CONFLICT OF INTEREST:

None.
FPGA-based Dual Core TRNG Design Using Ring and Runge-Kutta-Butcher based on Chaotic Oscillator
Authors: ALÇIN Murat , TUNA Murat , ERDOĞMUŞ Pakize , KOYUNCU İsmail
Published: February 2021

Despite the fact that chaotic systems do not have very complex circuit structures, interest in chaotic systems has increased considerably in recent years due to their interesting dynamic properties. Thanks to the noise-like properties of chaotic oscillators and the ability to mask information signals, great efforts have been made in recent years to develop chaos-based TRNG structures. In this study, a new chaos-based dual entropy core TRNG with high operating frequency and high bit generation rate was realized using 3D Pehlivan-Wei Chaotic Oscillator (PWCO) structure designed utilizing RK-Butcher numerical algorithm on FPGA and ring oscillator structure. In the FPGA-based TRNG model of the system, 32-bit IQ-Math fixed-point number standard is used. The developed model is coded using VHDL. The designed TRNG unit was synthesized for Virtex-7 XC7VX485T-2FFG1761 chip produced by Xilinx. Then, the statistics of the parameters of FPGA chip resource usage and unit clock speed were examined. The data processing time of the TRNG unit was achieved by using the Xilinx ISE Design Tools 14.2 simulation program, with a high bit production rate of 437.043 Mbit/s. In addition, number sequences obtained from FPGA-based TRNG were subjected to the internationally valid statistical NIST 800-22 Test Suite and all the randomness tests of NIST 800-22 Test Suite were successful.

En  la raza humana no existe ningún otro proceso diseñado tan exitosamente como el natural hecho del embarazo. Uno de los riesgos que se presenta en esta etapa es la  Hipertensión arterial, no obstante existen diferentes vías para el cuidado de las embarazadas dispenzarizadas como hipertensas o con riesgos a serlo. Generalmente, estos cuidados se basan en el reposo físico entre otras medidas profilácticas, disminuyendo así la efectividad de las intervenciones físicas, eso proporcionó inquietudes terapéuticas para solucionar un existente, latente y peligroso problema para lograr la prevención del riesgo hipertensivo durante el período de embarazo. Para ello se utilizaron métodos y  técnicas de investigación científica del orden teórico, empírico y procedimientos estadísticos. Estos permitieron diagnosticar, proponer acciones, aplicar las técnicas y ejercicios de relajación, para evaluar los resultados que consistieron en que al prevenir la aparición de esta enfermedad en aquellas embarazadas con predisposición a padecerla o que ya la padecen antes de comenzar el estado de gestación no es un mito. Se  concluye que las embarazadas con riesgos a padecer Hipertensión arterial o que ya sufren esta enfermedad si reciben ejercicios físicos y técnicas de relajación como método de prevención, disfrutarán de un embarazo y parto saludables.

La investigación se inició con un diagnóstico de fincas pertenecientes a la agricultura urbana y suburbana infestadas por Dichrostachys cinerea (L.) Wigth et Arm. Se determinaron en cuatro sistemas de uso (dos sistemas infestados por D. cinerea y dos sistemas agrícolas en explotación por 10 años luego de la deforestación del marabú y puesto en cultivo) en la zona de Becerra, finca Los Téllez del municipio Las Tunas. El objetivo fundamental fue valorar indicadores de calidad de los suelos Fersialíticos pardos rojizos sobre granitoides, que reflejen el grado de estabilidad de los suelos bajo el marabú y los cambios ocurridos por las prácticas de uso y manejo. Para evaluar el efecto de los sistemas de manejo sobre los indicadores de calidad de suelo se midieron indicadores químicos, (pH, P, Materia orgánica), físicos, (densidad aparente, contenido en arena, porosidad total) y biológicos, (densidad y biomasa de lombrices). Los resultados mostraron que los sistemas de D. cinerea resultaron los de mayor índice de calidad de los suelos tomando como indicadores materia orgánica, densidad aparente y biomasa de lombrices. Los sistemas cultivados alcanzaron la menor acumulación de carbono orgánico, densidad y biomasa de oligoquetos y porosidad total.
Economic valuation of paddy fields: Employment services providers for farmers

Agricultural land conversion (ALC) is economically profitable, but what the community does not pay attention to is the losses caused by the ALC. Economic valuation is one way to calculate the multifunctionality of paddy fields that have overall economic value, including the production function, provider of environmental products/services and socio-culture. This study aims at determining the economic value of paddy fields as employment services providers for farmers. The analytical method employed was the economic valuation. Research result: It shows that the conversion of paddy fields in Pasuruan Regency in 2014-2019 is quite high, averaging 777.7 Ha per year. The economic value of rice fields as an employment services provider in 2019 is IDR 1,922,772,319,000. This value tends to decline due to land conversion since 2014.
Perceptions on fisherman’s insurance: A case study in PPN Prigi, Jawa Timur

Published: February 2021

Coastal communities commonly depend on their income on marine resources with fishing produces as the main income. Their work is quite risky, as fishing is inextricable from work accidents, loss of life, loss of boats and equipment, personal health and safety, and safety of ship crews. This study aims to determine the mechanism of insurance implementation and fishermen’s perceptions of the Insurance Assistance Program for Fishermen in Prigi, Trenggalek, Jawa Timur. This present study employed descriptive qualitative. The data was collected through in-depth interviews, observation, and literature study. Results show that the number of insurance participants fluctuated, and even decreased every year from 2018 to 2020. Some of the causing factors were fishermen’s lack of interest in the insurance programs due to bad experiences in the past. They reported that the claim submission process was long and complicated when a work accident occurred. Lack of socialization of the insurance program had also made fishermen less familiar.

Abstract. The impact of emissions of volatile organic compounds (VOCs) to the
atmosphere on the production of secondary pollutants, such as ozone and
secondary organic aerosol (SOA), is mediated by the concentration of nitric
oxide (NO). Polluted urban atmospheres are typically considered to be
“high-NO” environments, while remote regions such as rainforests, with
minimal anthropogenic influences, are considered to be “low NO”. However,
our observations from central Beijing show that this simplistic separation
of regimes is flawed. Despite being in one of the largest megacities in the
world, we observe formation of gas- and aerosol-phase oxidation products
usually associated with low-NO “rainforest-like” atmospheric oxidation
pathways during the afternoon, caused by extreme suppression of NO
concentrations at this time. Box model calculations suggest that during
the morning high-NO chemistry predominates (95 %) but in the afternoon
low-NO chemistry plays a greater role (30 %). Current emissions
inventories are applied in the GEOS-Chem model which shows that such models,
when run at the regional scale, fail to accurately predict such an extreme
diurnal cycle in the NO concentration. With increasing global emphasis on
reducing air pollution, it is crucial for the modelling tools used to
develop urban air quality policy to be able to accurately represent such
extreme diurnal variations in NO to accurately predict the formation of
pollutants such as SOA and ozone.
Why we need radar, lidar, and solar radiance observations to
constrain ice cloud microphysics

Abstract. Ice clouds and their effect on Earth's radiation budget are one of the largest sources of uncertainty in climate change predictions. The uncertainty in predicting ice cloud feedbacks in a warming climate arises due to uncertainties in measuring and explaining their current optical and microphysical properties as well as from insufficient knowledge about their spatial and temporal distribution. This knowledge can be significantly improved by active remote sensing, which can help to explore the vertical profile of ice cloud microphysics, such as ice particle size and ice water content. This study focuses on the well-established variational approach VarCloud to retrieve ice cloud microphysics from radar-lidar measurements. While active backscatter retrieval techniques surpass the information content of most passive, vertically integrated retrieval techniques, their accuracy is limited by essential assumptions about the ice crystal shape. Since most radar-lidar retrieval algorithms rely heavily on universal mass-size relationships to parameterize the prevalent ice particle shape, biases in ice water content and ice water path can be expected in individual cloud regimes. In turn, these biases can lead to an erroneous estimation of the radiative effect of ice clouds. In many cases, these biases could be spotted and corrected by the simultaneous exploitation of measured solar radiances. The agreement with measured solar radiances is a logical prerequisite for an accurate estimation of the radiative effect of ice clouds. To this end, this study exploits simultaneous radar, lidar, and passive measurements made on board the German High Altitude and Long Range Research Aircraft. By using the ice clouds derived with VarCloud as an input to radiative transfer calculations, simulated solar radiances are compared to measured solar radiances made above the actual clouds. This radiative closure study is done using different ice crystal models to improve the knowledge of the prevalent ice crystal shape. While in one case aggregates were capable of reconciling radar, lidar, and solar radiance measurements, this study also analyses a more problematic case for which no radiative closure could be achieved. In this case, simultaneously acquired in-situ measurements could narrow this inability to an unexpected high ice crystal number concentration.
