The operator of the acid workshop S., 40 years old, 19 / V 1967, during a major overhaul, was cleaning the collector from under oleum (98% sulfuric acid): being in the collector, for 1.5 hours she shoveled the sludge into an iron bucket with a wooden shovel. The victim was wearing a gas mask, but she took it off twice for 5-10 minutes. When sludge containing sulfuric acid interacts with iron, free hydrogen was released. The latter combined with arsenic in the sludge, forming arsenous hydrogen, which caused acute intoxication in the apparatus operator.
The use of barium sulfate for surgical tattooing of flat hemangiomas
Authors: Safin G. G.
Published: March 2022

Flat hemangiomas are the most common congenital pathology. In the overwhelming majority, they are localized on the face [1-3] in the form of pink, red, burgundy spots of various sizes, sometimes occupying a large half of the face. The problem of treating flat hemangiomas continues to be relevant, since there is no universal method that allows in all cases to eliminate the cosmetic defect of facial skin coloring. One of the ways to treat the color discrepancy of the facial skin in this pathology is surgical tattooing with neutral dyes, which must meet the following requirements: 1) do not be toxic to the body and do not cause changes in the cellular elements of the skin, 2) be resistant to external factors, 3) do not dissolve, firmly located at the site of initial administration, and do not stain the underlying tissues.

Objective. To conduct a comparative analysis of mental disorders in dermatological and gastroenterological patients.

Materials and methods. The study involved 84 persons who formed two groups: group I included 42 patients with dermatoses without concomitant diseases of internal organs; group II consisted of 42 gastroenterological patients without a history of skin pathology. The groups were comparable by age, gender and social status; all were residents of Perm. The examination, in addition to general clinical and standard laboratory techniques, included a psychological study using special scales to determine personal characteristics, cognitive functions, and emotional disorders. Methods of parametric and nonparametric statistics were used to account for and analyze the results.

Results. Mental changes were found in the majority of dermatological and gastroenterological patients, mainly emotional disorders were observed. According to the indications of the hospital anxiety and depression scale HADS, Hamilton scale, Tsung self-assessment scale, anxiety was more often detected in dermatological patients, and depression in gastroenterological patients.

Conclusions. The majority of dermatological and gastroenterological patients have mental disorders, which are characterized by disorders of the emotional sphere. A significant difference was revealed in the structure of emotional disorders in dermatological and gastroenterological patients: anxiety was mainly determined in dermatological patients, and depressive symptoms prevailed in gastroenterological patients. The data obtained will help to use a comprehensive approach to the treatment of comorbid mental disorders, which will improve the quality of medical care.

Accidental opportunities? Women in family businesses taking the lead in a new market economy
Authors: Boateng Doris A.
Published: February 2022

Social workers have been working to empower women of diverse backgrounds across several practice settings. However, for women entrepreneurs in Ghana generally and those in family businesses specifically, some socio-cultural factors have persisted to hinder their abilities to promote and sustain their businesses. This paper describes the ways in which women in family businesses in Accra, Ghana have identified and leveraged opportunities presented by structural, cultural, socio-economic, and technological changes to ensure the success of their businesses. The study employed a qualitative research approach with purposive and snowball sampling used to identify and interview 15 women in family businesses. Findings indicate that women in family businesses in Accra, Ghana have creatively made use of the changing socio-cultural and economic landscape of the country to promote their businesses through three main trends which are significant in business growth: the advent and increasing use of social media, innovative business practices, and weakening patriarchy. We recommend that social workers apprise themselves of contexts which have unequal consequences for women and mobilize around these changes to help women entrepreneurs to take full advantage of the opportunities that are being offered in Ghana’s emerging economy.
Incorporating Photovoice Into a Community-Based Intervention With Latinx Families
Authors: Lechuga-Peña Stephanie , Mitchell Felicia M. , Poola Charlene , Gutiérrez Mónica , Rivera Lizette A.
Published: February 2022

Photovoice is a qualitative community-based participatory research (CBPR) method used by researchers and communities to inform policy and advocate for community change. Photovoice was piloted within an established community-based intervention, Your Family, Your Neighborhood (YFYN), within a predominantly Latinx community. YFYN is a dual-generation, evidence-based, manualized curriculum supporting and strengthening bonds between parents and their children while fostering neighborhood social cohesion among families living in low-income communities. The photovoice project was conducted with five families (n=20 participants) in English and Spanish. Participants guided the photovoice process to uncover complex community issues from their direct perspectives to accurately capture the challenges and strengths they encounter in their community. Community challenges identified by participants included the dumping of trash in their neighborhood, inadequate space for their children to play, and heavy traffic that impedes their ability to walk their children to school safely. Participants identified three main community strengths: the local park, the Boys & Girls Club, and personal connections with other YFYN family participants. When participants guide the photovoice process, it helps stakeholders understand and uncover complex issues from community members’ direct perspectives to capture the meaning of the issues accurately. Production of knowledge from the community rooted in their lived experience can help reshape the narrative of Latinx families living in low-income communities and allows for social workers to more adequately respond to their specific needs.
Ending Our Silence
Authors: McElderry Cathy , Jones V. Nikki
Published: February 2022

The U.S. has never fully addressed the legacy of chattel slavery and institutionalized racism. H.R. 40 – Commission to Study and Develop Reparation Proposals/Processes for African Americans Act presents an opportunity to engage in a national discourse on the topic of federal reparations for the injustices of slavery and the present-day impact. The intent of the bill is to establish a commission to examine remedies for slavery and institutionalized discrimination. Enacting this bill is an important step in acknowledging the fundamental injustices of slavery. Social work, as a profession, has yet to acknowledge a position on this important issue. The historical context of reparations and institutionalized discrimination are presented to initiate a dialogue and call to action among social workers. Social workers are in a unique position to play an integral role in addressing the issues challenging passage of H.R. 40. The advocacy expertise of social workers situates them to support reparations as a policy priority that aligns with the cardinal values of the profession. Through capacity-building, the social work profession can dispel the myths and fears associated with reparations and move H.R. 40 forward.
Advancing Child Trauma Screening Practices
Authors: Evans Kylie E. , Jennifer A. King  , Megan R. Holmes
Published: February 2022

Child trauma screening practices have advanced considerably as child-serving systems have increasingly incorporated early identification and intervention into trauma-informed models of care. While research points to the necessity of screening practices that attend to a child’s developmental capacities, cultural background, relational strengths, contextual details surrounding the traumatic experience, and complex trauma considerations, many of these features remain absent in common brief screening measures used in practice. Pictorial screening measures may offer an innovative opportunity to address attentional concerns and developmental capacities of young and complexly traumatized children, yet are understudied in this area. The purpose of this paper is threefold: 1) highlight areas for expansion within current brief trauma screening models, 2) propose an evidence-informed framework for a pictorial complex trauma screening tool for children, and 3) offer implementation considerations for piloting the proposed screening tool. Piloting and implementation considerations address the importance of cognitive interviewing, cultural sensitivity, development of a companion response and referral protocol, and embedding principles of trauma-informed care in the training and implementation process.
Pandemic Road Map
Authors: Reay Susan
Published: February 2022

During the unprecedented early stages of COVID-19, few protocols were established to support overall student wellness in social work field placements. In response to the overwhelming need for a contextual framework to promote wellness and determine the next steps in mitigating health risks, faculty developed a unique solution in a dynamic situation. Rooted in the university-sponsored dimensions of wellness, BSW and MSW students developed wellness plans that were integrated into the field placement course. These plans were intended to enhance students' ability to evaluate their well-being and encourage them to plan wellness activities. The wellness plan was critical in determining a student's ability to continue their planned learning activities amidst broad systemic factors, which impacted their social work field placement experiences. Developing the wellness plan encouraged students to articulate unmet needs and provided a mechanism for faculty to offer relevant university-sponsored resources. This model provides a framework with implications for social work education. The prioritization of student wellness during field placement creates a road map for the future. Given that wellness is an essential component of social work practice, social work students must have the tools to evaluate and implement wellness strategies, which can be applied throughout the student's social work career.
Creating SPACE
Authors: Popescu Marciana L. , Alonzo Dana
Published: February 2022

Escalating conflicts, climate change, rising inequality, a global pandemic: Complex emergencies are leading to a reconfiguration of the world as we know it. Rapid flow of information allows increased visibility and understanding of the impact of these crises on the most vulnerable. Yet at the same time, marginalized communities are rendered invisible, and their fundamental human rights are being erased. In such contexts, providing a framework that engages communities and ensures that they are at the core of any capacity building endeavor is an important professional mandate for international social work and social development. This paper introduces the Strengths and Participation to Accomplish Capacity and Empowerment (SPACE) conceptual framework for capacity building and community engagement in international social work practice. This conceptual framework builds on both the strengths perspective and empowerment theories, and promotes a rights-based approach for international social work and social development. SPACE was first used to design and implement a training-of-trainers program in two communities in Guatemala. The training’s effectiveness in building capacity was evidenced by the impactful networks strengthened or developed as a result of the training in developing COVID-related responses. Further applications of this framework can improve international social work practice and advance rights-based approaches to sustainable development.
Fall 2021

Published: February 2022

In the Fall 2021 issue of Advances in Social Work, we are pleased to present 16 full-length papers written by 30 authors from different regions of the U.S. including Puerto Rico as well as from Ghana. An underlying theme of many of these contributions is the opportunity brought about through various struggles:  patriarchal systems leading to innovative women entrepreneurs, social distancing measures spawning new ways of learning virtually and new ways of practicing social work, and mental health challenges exposed among elite athletes leading to new frontiers of practice.  The variety of social work contributions to wellness, advocacy, and social justice seem to be ever-expanding.
Interestingly, despite the trend toward multiple-authored papers over time, 7 of the papers in this issue are solo-authored--perhaps an artifact of the pandemic. Each paper is introduced briefly below, followed by our annual recognition of reviewers for Advances in Social Work.

AIM: To demonstrate the outcomes of endoscopic endonasal dacryocystorhinostomy (En-DCR) with an novel lacrimal ostium stent (LOS) which was performed in patients with recurrent epiphora after failed external dacryocystorhinostomy (Ex-DCR) and analyze the causes of failed Ex-DCR.
METHODS: From September 2015 and December 2017, the clinic data of 29 cases suffered from recurrent epiphora after failed Ex-DCR was reviewed. The LOS were implanted into the ostium at the end of the revisional surgery. The causes of failed Ex-DCR were analyzed before revisional surgeries. Outcome of revisional surgeries with the new device were evaluated as well.
RESULTS: The major causes of failure of the external approach were synechiae formation in the nasal ostium (29/29), followed by inadequate removal of the bony wall (21/29), nasal synechiae formation between lateral wall of nose and middle turbinate (11/29), and the bone opening was not in good location (7/29). The rate of success after revisional surgery was 82.76%. Re-obstruction of the ostiums were found in 5 failed cases.
CONCLUSION: Endoscopic approach with a novel LOS may be an effective procedure to manage recurrent epiphora after previous failed Ex-DCR surgery. Synechiae formation in the nasal ostium and inadequate removal of the bony wall were the major causes of failure of Ex-DCR.

AIM: To evaluate the long-term anatomical and visual outcomes of drusenoid pigment epithelial detachment (D-PED) in intermediate age-related macular degeneration (AMD) eyes treated with 577 nm yellow subthreshold micropulse laser (SML).
METHODS: In this retrospective study, 21 eyes of 16 patients with D-PED in intermediate AMD were consecutively included and assessed. All the eyes were treated with 577 nm SML in several sessions according to D-PED growth status. The logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) were assessed at the initial visit and after treatment. Spectral-domain optical coherence tomography (SD-OCT) was performed to evaluate the D-PED lifecycle by volumetric calculations. Regression analysis was used to determine the breakpoint, growth, and collapse rate of the D-PED lesions. The progression to advanced AMD was also documented.
RESULTS: All the eyes were treated with SML for 2.9±1.0 sessions. The mean follow-up period was 25.3±12.6mo. The BCVA was stable from the baseline to final visit. All the eyes were categorized into two groups according to the anatomical changes of the D-PED lesion: the collapse group (n=6, 28.6%) and non-collapse group (n=15, 71.4%). The change in logMAR BCVA did not differ significantly between the collapse group 0.00 (-0.31, 0.85) and non-collapse group 0.00 (0.00, 0.00; P=1). Regression analysis showed that the growth rate was significantly higher in the collapse group (0.090±0.095 mm3/mo) than in the non-collapse group (0.025±0.035 mm3/mo; P<0.001). One eye (4.8%) developed macular neovascularization at 11mo after SML treatment in the non-collapse group. Three eyes (14.3%) developed geographic atrophy (GA) in the collapse group.
CONCLUSION: Compared to the natural course of D-PED reported by previous studies, our results preliminarily show that SML can alleviate visual loss and possibility of progression to advanced AMD in eyes with D-PED in intermediate AMD. A controlled clinical trial needs to further verify the benefit of the intervention.
Reading Together
Authors: Perkins Tanya
Published: March 2022

This teaching reflection examines how “reading together” was fostered in synchronous and asynchronous online environments in two undergraduate creative writing courses through participation in a virtual book club. In the first course, prior to the pandemic, students had the option of meeting in person or via Zoom while we read Daisy Johnson’s Oedipus Rex retelling, Everything Under, for the book club. In the second course, during the pandemic, students had virtual synchronous and written participation choices while we read together Jessica Anthony’s political satire, Enter the Aardvark, with the author visiting in two sessions. In both cases, the goals were consistent: to get students reading as writers; to foster intrinsic motivation through personal choice; and to satisfy students’ desire for community connection while still accommodating personal schedules and geographical location. A virtual book club lets students read on their own schedule and in their own space, but still share their experience and observations with peers over greater distances (and time zones) than would otherwise be possible.

Diagnostics of the State of Safety-Oriented Enterprise Management System Using Neural Networks
Authors: Havlovska Nataliia , Koptieva Hanna , Babchynska Olena , Rudnichenko Yevhenii , Lopatovskyi Viktor , Prytys Vadym
Published: February 2022

Enterprise management is based on the need to make and justify management decisions that contribute to its development. It is almost impossible to determine the risk of a particular managerial decision, and excessive risk in the implementation of individual projects can lead to loss of business. Therefore, management faces the need to find a balance between benefits and risks, at which, on the one hand, it will be possible to develop a company and, on the other hand, adhere to postulates of safetyoriented management. Since management decisions cannot be foreseen for all possible situations and combinations of risk-benefit ratios, a universal model is proposed. It implies a golden ratio, depending on the limited number of current conditions, that would satisfy an enterprise management from the standpoint of sufficient justification on a decision. The article proposes a probabilistic neural network architecture and Matlab parameters of a probabilistic neural network for diagnosing the states of a safety-oriented control system. The proposed model in the form of a probabilistic neural network generates a response to input data on previous month under estimation, and forms an optimal state for a next month.

Published: February 2022

Sentiment analysis of Twitter data is quite valuable for determining the market opinion. Twitter sentiment analysis is more challenging than generic sentiment analysis owing to slang and misspellings. The techniques utilized for evaluating the sentiment of tweets that have the greatest importance for the success of an Initial Coin Offering (ICO) are machine learning approaches. In this study, we examined market sentiment and used Expert Ratings to predict the success of ICOs in the Australian and Singapore markets. Based on 68,281 tweets from 57 ICOs across four industries: business services, cryptocurrency, entertainment, and platform. Several classification methods were investigated, including Support Vector Machines (SVMs), Logistic Regression (LR), Random Forest (RF), and Naïve Bayes (NB). The outcomes indicated that sentiment analysis of tweets and expert ratings may be used to forecast the success of an initial coin offering. The results indicate that the suggested model is capable of accurately assessing the tweets of the ICO Successful with a maximum accuracy of about 94.7 % when implementing the Support Vector Machines (SVMs) classifier.

Calculation of Electric Circuits Using the Fast Kirchhoff Method
Authors: Ďuriš Viliam , G. Chertanovskiy Aleksey , G. Chumarov Sergey , V. Kartuzov Aleksandеr
Published: February 2022

The Laws of Ohm (1826) and Kirchhoff's laws (1847) are the basis for the theory of electric circuits. Using them when calculating electrical circuits, we need to create and solve a system of equations for circuit currents and nodal voltages. Kirchhoff's Theorem (1847) on finding currents of branches does not require the compilation and solution of this system of equations. Belov G. A. and Zakharov V. G. (2003) re-proved the Kirchhoff's Theorem (1847) and supplemented it with eight rules for calculating electric circuits. With the help of these rules, the currents of branches and nodal voltages are formed from a loop or nodal determinant and an electric circuit. At the same time, duplicate operations occur in the process of forming expressions of currents and voltages according to these rules. In this paper, we prove the theorems of the Fast Kirchhoff method about a complete and truncated tree, about a unique branch and loop, about common branches and loops, as well as the formulas of the Fast Kirchhoff method for generating currents of branches and nodal voltages.In the Fast Kirchhoff method, when calculating an electric circuit, there are no duplicate operations when generating currents of branches and node voltages, and this reduces the calculation time.

The aim of this research is the analysis of the length-weight relationships and the condition factor of chub (Squalius cephalus L.) from certain rivers in northeastern Bosnia and Herzegovina that belong to the Black Sea basin. The research was conducted on 200 specimens of chub (Squalius cephalus L.) during 2019. The estimated values of the total body length ranged from 10.06 cm to 29.33 cm, with the mean body length of 15.97 cm in the total sample. The fish weight ranged from 8.0 g to 264.5 g, with the mean value of 46.8 g. The length-weight relationships of chub were determined in relation to their age classes. The fish in age classes 1+, 4+ and 5+ indicate a positive allometric growth (b > 3), while the fish in age classes 2+ and 3+ have a negative allometric growth (b < 3). The analysis of the coefficient of determination, R2, shows that the fish in age classes 1+ i 4+ have the highest values of this coefficient (> 0,9). ANOVA analysis of the condition factor of chub based on age classes indicates that there are no statistically significant differences in the distribution of this factor between the fish of the same age classes from different localities (P < 0.05).

IRT is more sensitive to item characteristics that can estimate students’ ability. This study implements IRT in a quiz assessment system, compares the results of the CTT and IRT, then analyses the functionality and usability of the built system. The system was tested by 50 respondents using 30 question items with 5 answer choices. The collected data is automatically assessed by the system using CTT and IRT calculations. The results showed differences in ranking between CTT and IRT methods. Using the IRT method, there were 14 respondents who experienced an increase in rank, 19 respondents experienced a decrease in rank, and the remaining 17 respondents did not experience a change in ranking. The functionality of built system was tested with the Blackbox Testing method and it has passed all the test functions. The usability of the system was also tested by involving 23 respondents using the System Usability Scale (SUS) questionnaire and the SUS score showed that the system can be accepted by users.
