Authors: Cho Yong Heui , Lee Haengseon , Byun Woo Jin , Kim Bong Su , Chong Young Jun 
Published: February 2023

<p>A numerically efficient method of shooting and bouncing rays for sparse particles (SBR-SP) is presented to analyze a large two-dimensional (2D) array of magnetodielectric circular cylinders which are distributed with any positions, sizes, and media on the <em>xy</em>-plane. Iterative- and closed-forms of the SBR-SP are used to understand the convergence and accuracy characteristics of a large array of cylinders and we also compare them with the results obtained by a mode-matching technique, thus resulting in favorable agreement. Especially, the closed-form of the SBR-SP with GPU acceleration is fast and accurate enough to obtain various echowidth behaviors of a 80×80 square array within 71.8 s. In addition, a statistical analysis for a randomly distributed array with 6,400 elements is conducted in terms of mean and standard deviation and we obtain that initial shooting rays excited by an incident field are strongly dominant in statistical behaviors of scattering patterns. Our algorithm based on the SBR can be extended to three-dimensional (3D) problems where we model a large array of lossy dielectric spheres for the estimation of rain attenuation and signal variation.</p>

The present study has been made to evaluate the ground water quality of Samba town of Jammu division of J & K state . The solid waste ge nerated in urban areas is i ncreasi ng day-by-day. Many municipalities and corporations are facing the problem of managing large volumes of solid waste generated in their area. One of the alternatives for disposal of solid waste is filling the depressions, drains, nallah, open spaces etc. In the persent study, a big nallah flowing through Samba town carries huge load of pollutants in the form of refuse and waste water opens at many places into self-created garbage pits. Ground water monitoring was carried out at two stations around garbage pit to assess the ground water quality of hand pumps used by the residents of the area for domestic and other uses. The study revealed that the quality of ground water, however, confirm to the drin king water quality standards but th ere is need for periodic evaluation of various water quality parameters as well as adopti on of proper water quali ty management as natural quality of ground wate r is being degradaed near the garbage pit.

Photochemic al reduction of Cr (VI) i nto Cr (III) has been reported earlier in the presence of glycerol (Yurkow et al., 2002). The introduction of EDTA salt in the reagent that is prepared to have an incomplete reaction enhances the rate of reduction as it enhances th e ionic strength considerably. The acid and a carbon source was provided through the reaction of glycerol and concentrated Sulphuric acid. The reagent thus formulated is efficient enough to reduce the hexavalent chromium as evident by its appearance in the solut i on .

A study on the water quality of three freshwater ponds connected in series at Gudavi village near Shimoga is studied for of physico-chemical factors. The DO was 8.81 mg/l in Kallambi, 3.84 mg/l in Vaddekere and 7.78 mg/l in Gudavi pond respectively and such a variation is attributed to the fecal (guano) droppings discharged by about 12,000 resi den t birds which in clu de Egre ts, Cormorants, Ibises, Herons, water fowl s and oth er wetland dependent specie s in the Vaddekere of the sanctu ary. A comparati ve study of nutrients and BOD levels in the three consecutive ponds revealed that the Vaddekere pond is most polluted. Due to this reason th e water qu ality i n the Vaddeke re was altered an d the e mergen t trees on the pond which were use d for roosting and nesting by the birds are affected and evidenced by dying of trees. The death of island trees will lead to loss of roosting and nesting sites for Gudavi birds. Hence an urgent action plan to protect the trees or replanting new trees i n the water bodies by creating islands eve ry year is suggested.

Published: February 2023

Studies on the move analysis in the various sections of research articles have developed rapidly. However, the studies on the communicative moves in the discussion section particularly written by vocational college students are still limited. In fact, those students categorized as the novice writers inevitably need illustrations of how to write the proper discussion related to their findings. Therefore, this study was aimed at exploring the communicative moves and the move cycle series in the discussion sections of the final project reports written by EFL vocational college students in one of the state polytechnics in Indonesia. The method used is a discourse analysis on 15 discussion sections. The results showed that Move II, Move IV, and Move I were used frequently in all students’ discussion sections. Pertaining to the move cycle series, students fulfilled the rhetorical functions of introduction (1) and evaluation (4+2 or 2+4) but the cycle for showing the conclusion was commonly not used. The results provide references and the real applications pertinent to communication moves in the discussion section by EFL students.

Background: Occupational contact dermatitis (OCD) is an inflammatory response caused by contact with allergens or irritants in the work environment, and this disease is most often found as an occupational disease. Personal protective equipment (PPE) is a safety tool that must be used by workers to protect the body from possible potential hazards in the workplace. Construction workers, woodworkers, batik workers, and farmers can take preventive measures to avoid the occurrence of OCD. This study aimed to determine the relationship between the length of work and the use of PPE on the incidence of OCD on the hands of woodworkers in Serenan, Klaten.
Methods: Cross-sectional analytic observational study. A total of 30 research subjects participated in this study. The research subjects were woodworkers in Serenan, Klaten, Indonesia. Univariate and bivariate data analysis was carried out with the help of the SPSS program.
Results: The majority of research subjects with OCD have worked for more than 3 years and do not use PPE. Studies show that there is a relationship between the length of work and the use of PPE with the incidence of OCD.
Conclusion: There is a significant relationship between the length of work and the use of PPE on the incidence of OCD on the hands of woodworkers in Serenan, Klaten, Indonesia.
Re-defining silence in unvoiced dialogues in storying-play: The sound of affects

Published: February 2023

This article chronicles three stories selected from a post-intentional phenomenological study conducted by the first author. The authors aim to investigate affective connections in children’s silent play by addressing three research questions: (a) How do children engage in dialogue with the teacher, their peers, and the material environment without words? (b) What emotions are produced in silent play? and (c) What changes in children’s affective connections occur through silence? We drew on the notion of intentionality in post-intentional phenomenology to illuminate meanings of the phenomenon for individuals about what they felt and experienced. With a focus on intentionality, we delved into the ways children meaningfully communicated with others and connected to the environment in their unspeaking moments. We also took on a posthuman notion of intra-actions to rethink silence as an inaudible yet sensible sound communicated between children and things. The prior studies showed that children’s silence was a mode of expression. Through storying the silent play-stories, we offered two alternative meanings of silence––intra-active communication with people and things and inaudible inner wellbeing, in addition to a mode of nonverbal expression as identified in prior studies. The findings are significant in enriching and renewing our understanding of children’s silence in inclusive ECE environments. Silence is re-defined as a mode of embodied communication and affective connections. This article invites researchers and educators to genuinely “listen” to children’s stories, even in silent play.
Aversion, interpretation and determinability: Three factors of uncertainty that may play a role in psychopathology
Authors: Moul Caroline , Don Hilary J. , Livesey Evan J. 
Published: February 2023

AbstractThis opinion piece considers the construct of tolerance of uncertainty and suggests that it should be viewed in the context of three psychological factors: uncertainty aversion, uncertainty interpretation, and uncertainty determinability. Uncertainty aversion refers to a dislike of situations in which the outcomes are not deterministic and is similar to conventional conceptions of (in)tolerance of uncertainty. Uncertainty interpretation refers to the extent to which variability in an observed outcome is interpreted as random fluctuation around a relatively stable base-rate versus frequent and rapid changes in the base-rate. Uncertainty determinability refers to the (actual or perceived) capacity of the individual to generate any meaningful expectancy of the uncertain outcome, which may be undeterminable if predictions are updated too quickly. We argue that uncertainty interpretation and determinability are psychological responses to the experience of probabilistic events that vary among individuals and can moderate negative affect experienced in response to uncertainty. We describe how individual differences in basic parameters of associative learning (modelled by a simple learning window) could lead to this variation. To explain these hypotheses, we utilise the distinction between aleatory uncertainty (the inherent unpredictability of individual stochastic events) and epistemic uncertainty (obtainable knowledge that the individual lacks or perceives to be lacking). We argue that when expectancies are updated quickly, epistemic uncertainty will dominate the individual’s representation of the events around them, leading to a subjective experience of the world as one that is volatile and unpredictable.

Abstract
Due to their likely tidally synchronized nature, (ultra)hot Jupiter atmospheres should experience strongly spatially heterogeneous instellation. The large irradiation contrast and resulting atmospheric circulation induce temperature and chemical gradients that can produce asymmetries across the eastern and western limbs of these atmospheres during transit. By observing an (ultra)hot Jupiter’s transmission spectrum at high spectral resolution, these asymmetries can be recovered—namely through net Doppler shifts originating from the exoplanet’s atmosphere yielded by cross-correlation analysis. Given the range of mechanisms at play, identifying the underlying cause of observed asymmetry is nontrivial. In this work, we explore sources and diagnostics of asymmetries in high-resolution cross-correlation spectroscopy of hot and ultrahot Jupiters using both parameterized and self-consistent atmospheric models. If an asymmetry is observed, we find that it can be difficult to attribute it to equilibrium chemistry gradients because many other processes can produce asymmetries. Identifying a molecule that is chemically stable over the temperature range of a planetary atmosphere can help establish a baseline to disentangle the various potential causes of limb asymmetries observed in other species. We identify CO as an ideal molecule, given its stability over nearly the entirety of the ultrahot Jupiter temperature range. Furthermore, we find that if limb asymmetry is due to morning terminator clouds, blueshifts for a number of species should decrease during transit. Finally, by comparing our forward models to those of Kesseli et al., we demonstrate that binning high-resolution spectra into two phase bins provides a desirable trade-off between maintaining signal to noise and resolving asymmetries.

Published: February 2023

Abstract
Extended very-high-energy (VHE; 0.1–100 TeV) γ-ray emission has been observed around several middle-aged pulsars and referred to as “TeV halos.” Their formation mechanism remains under debate. It is also unknown whether they are ubiquitous or related to a certain subgroup of pulsars. With 2321 days of observation, the High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory detected VHE γ-ray emission at the location of the radio-quiet pulsar PSR J0359+5414 with >6σ significance. By performing likelihood tests with different spectral and spatial models and comparing the TeV spectrum with multiwavelength observations of nearby sources, we show that this excess is consistent with a TeV halo associated with PSR J0359+5414, though future observation of HAWC and multiwavelength follow-ups are needed to confirm this nature. This new halo candidate is located in a noncrowded region in the outer galaxy. It shares similar properties to the other halos but its pulsar is younger and radio-quiet. Our observation implies that TeV halos could commonly exist around pulsars and their formation does not depend on the configuration of the pulsar magnetosphere.

The purpose of this study is to identify the essentials of corporate MOOCs' application to the leading organizations. This basic research was conducted using a qualitative research synthesis technique. The statistical population includes documents retrieved by searching the Persian and Latin web databases (n=165) using a criterion sampling method (2013- 2020). A total of 73 sources were selected. Theoretical saturation of themes was reached by the 48th sample. In order to collect data, the library research method was used. The collected data were then analyzed using a thematic analysis technique. Finally, to validate the proposed model, a total of 6 experts in different fields were selected using a purposive sampling method, and they approved the final model after modifications. Based on the research findings, the essentials identified include: the main personal, educational, and organizational themes. Clarification of the logic behind and reason for learning is among essentials in designing and formulating any learning from virtual training (e-learning). This is of paramount importance, especially in learning based on corporate MOOCs as an innovation and transformation towards training and improving human resources. This logic prevents the possible resistance of managers and officials, and even the organizations and corporations' staff themselves to learning using corporate MOOCs.
Analysis of Empathic Experiences in Video Games with Microblogging

Published: February 2023

Empathy refers to what people experience and feel. Experts believed that empathy is an emotional intelligence skill that can be trained and taught. Therefore, it is very important to explore ways to experience and teach emotional empathy. Empathy experiences can be stimulated by reading fiction and other narratives, storytelling, watching movies, and also playing computer games. In this work, our objective is to investigate the effect of video gaming on empathy using a microblogging tool designed to collect user experiences related to empathy. The aim of this research is to contribute by providing a tool to teach, experience, and measure empathy. This research applies quantitative and qualitative methods. We conducted two studies: (1) investigating the correlation between empathic experiences and video games, and (2) a laboratory experiment to evaluate microblogs as a tool for interviews and media to express feelings or opinions related to empathy. Quantitative data were obtained from the IRI questionnaire. We developed and implemented a microblogging tool. Study 1 involved 100 participants, and study 2 involved 43 participants. As a result, we find that during the interventions, mean scores increase more for male than for female participants. The impact of playing the video game toward empathy is to raise players' fantasies. The game's story or narrative has the most important role to affect players' feelings. We also explore the potential of a microblogging tool for acquiring qualitative data related to empathy experiences and the effect of playing games.

In the Swiss education system the cantons oversee educational matters, practically meaning there are 26 different school systems. This is also reflected in the graduation exam, which is organized locally in every high school. Based on this assessment and their preference, students are admitted to university without any additional entrance exam. This motivated us to create an online self-assessment. Its two mathematical parts serve a different purpose: one evaluates basic mathematical skills, and the other one deals with abstract reasoning that gives students a flavor of university mathematics. Additionally, the online self-assessment contains a set of metacognition questions regarding motivation, expectations and attitude towards mathematics. Our goal is that students to identify their strengths and help them make a more informed study choice.
The technical tool used for the implementation is STACK, an open-source online assessment system in mathematics. Concerning this use case of STACK, we are currently collecting students’ feedback. We will present our first conclusions on this matter, which serve as a basis for further adjustments of the material.

The aim of current study was to survey genetic variability of PALM gene’s exon 3 and 4 by PCR-SSCP and DNA sequencing in Zel and Lori Bakhtiari sheep breeds. The SIFT (Sorting Intolerant from Tolerant) and PHyre2 program were used to predict the possible impact of amino acid substitutions on performance and structure of the paralemmin protein. A total of 140 animal's from 2 Iranian sheep breeds with different fat metabolisms, Lori-Bakhtiari and Zel sheep breeds were considered. The results showed that there are two polymorphic sites including a nonsynonymous substitution and an insertion mutation (49bp). Non-synonymous mutation deduced Thr20Ala amino acid exchange and ensuing two different structures for paralemmin protein that could be potentially affect protein structure and function during the interaction with glutamate in the cytosolic surface of plasma membrane. PALM gene, according to evolutionary path, is classified into two separate categories. In first covey, Gallus gallus and in second one, other species in several branches, so that the sequence of cow and sheep is placed in a sub-branch which forms a clade beside goat. Comparison of illustrated coding region sequences, PALM gene among different species, is of orthologous which are derived from a common ancestor.
