Published: June 2022

Introduction: Gynecomastia or the enlargement of breast tissue in men is one of the most common problems. Surgical management includes surgical excision or liposuction or both based on the grade. Surgical excision by Subcutaneous mastectomy(SM) is the criterion standard for the management of gynecomastia with only glandular hypertrophy without skin excess. We have evaluated the ease, safety and pitfalls of SM with tumescent technique.
Aims and objectives: To describe our technique of tumescent subcutaneous mastectomy (TSM), its operative ease, post-operative analgesia, and complications.
Patients and methods: The study was conducted in the department of plastic surgery of a tertiary care hospital from 2018 August to 2021 July. 53 SM without liposuction were included in the study.
Operative procedure: Infiltration solution consisted of Ringer Lactate - 500ml + 2% Lignocaine (12.5ml) + 1:1000 Adrenaline (0.5ml) + 0.5% Bupivacaine (12.5ml). 200-250 ml of tumescent solution was used per side using four-plane technique (Sub glandular, glandular, supra glandular and subdermal). SM was done using a standard technique. Operative time, ease of surgery, duration of post-operative analgesia and post-operative complications were recorded on a preformed questionnaire.
Results: 80% operating surgeons reported very good visualization of tissue planes and 79.2% reported dissection was very easy. 85% of the excisions were performed using 2 or less gauze pieces. Post-operative analgesia was achieved for 4-6 hours in more than 75%. Complications like seroma (7.5%), epidermal loss (3.8%), contour abnormality (1.9%) and nipple flattening (3.8%) were noted.
Discussion: The effects of tumescent components like hydro-dissection, vasoconstriction and analgesia added to the benefits of this technique. The complications noted were like or less compared to standard SM.
Conclusion: TSM being safe and easy, with an additional benefit of post-operative analgesia, is a worthy option in the management of gynecomastia with glandular hypertrophy without skin excess.

Published: June 2022

Introduction –
In the management of SCC of the Head and Neck (H N) region, lymph node metastases is considered one of the most significant negative prognostic factor. Elective Surgery i.e Elective Neck Dissection (END) is considered standard and optimum management policy in early stage clinically node negative (cN0) oral and oropharyngeal SCC, as even modern imaging modalities are not able to reliably detect or exclude occult micrometastases. Surgical treatment options for cervical lymph node metastases are associated with significant morbidities like impairment of shoulder function and contour changes, lower lip parasthesia, postoperative neck stiffness, nerve injury, and pain. Radiation treatment of the neck is associated with skin reactions, xerostomia, dysphagia, carotid artery stenosis, and hypothyroidism. The objective of our study is to systematically review, published literature regarding the application of the Sentinel Lymph Node Biopsy (SLNB) technique in clinically node negative(cN0) patients of early HN Squamous Cell Cancers (SCC).
Material And Methods –
A thorough Systematic Review of available publications and their references, was done and all relevant articles were included in this review.
Discussion –
Many authors have reported better Overall Survival (OS), Disease Specific Survival (DSS), and Disease Free Survival (DFS), when the SLNB protocol was used. The only disadvantage could be that Free Soft Tissue Disease in the neck in the absence of lymph node involvement, can be missed.
Conclusion –
Recently published results on SLNB by various Trials, Meta analyses and Systematic Reviews have presented, it as a promising alternative to conventional methods of Neck management in cN0 HN cancers. It may decrease morbidity associated with radical surgery or radiotherapy and ensure a better quality of life in a select group of HN cancer patients.

Authors: K Swetha , Singh Shailendar , B Jyothi , R Manasa
Published: June 2022

Background: Pediatric diarrhea is the 3rd foremost cause of childhood mortality all over the world. Although these are self-limiting diseases, irrational antibiotic use and polypharmacy are prevalent in their treatment. Antimicrobial therapy is recommended in bacterial diarrhea and severely malnourished children only. Inappropriate use of drugs for the treatment of acute diarrhea can be minimized by adhering to standard guidelines.

Aims and Objectives: The objectives of this study were as follows: (1) To evaluate the appropriateness of drug treatment in Acute Pediatric Diarrhea and (2) to assess the appropriateness of antibiotic treatment in diarrhea based on modified Kunin’s criteria.

Materials and Methods: A prospective observational study was conducted for 12 months at the pediatric inpatient unit of Bidar Institute of Medical Sciences teaching hospital, Bidar. Prescriptions of 400 cases of acute diarrhea were evaluated for the appropriateness of drug usage using Indian Academy of Pediatrics (IAP) guidelines and modified Kunin’s criteria. Results: Among the 400 acute diarrhea cases, majority were male (54.75%) and below 5 years (58.25%). Oral rehydration solution (ORS) was given to 337 patients and IV fluids to 324 cases. About 55.5% patients were prescribed antibiotics. In 75.67% prescriptions, the antibiotic use was not necessary (modified Kunin’s criteria category V). Only 12.5% prescriptions adhered to IAP guidelines (2006), which included ORS and Zinc. About 54.5% patients were prescribed probiotics and 80% were prescribed antiemetics (ondansetron), which is not appropriate as per guidelines.

Conclusion: Majority of patients were prescribed ORS, but only few were given zinc as an adjunctive therapy. Thus, we found that adherence to IAP 2006 guidelines was very low in our setup. Based on our observations, we suggest that prescribers should make use of standard treatment guidelines and choose appropriate drugs and their formulations so that irrational use of drugs can be minimized.

Authors: Rolando Paola , n Rocio , Montenegro Milena , a Luis
Published: June 2022

Background: Heat stress result in a mild reduction on milk production, while long term heat stress exposure can severely affect the productive and reproductive performance in dairy cattle.
Aim: The objective of this study was to quantify the relationship between reproductive performance and temperature-humidity index in dairy cattle farms in Lima, Peru.
Methods: Monthly service, conception and pregnancy rates were measured on four dairy farms from four different Lima localities as reproductive performance indicators, along with an index of heat stress, maximum daily temperature humidity index (Max THI), during a three-year period. In order to establish the relationship between the max THI and the reproductive performance indicators, a multiple regression analysis was made which considered the variable farm and year as explicative variables.
Results: The regression model showed an adjusted R-squared of 33.5% with an estimated standard error of 5.75% and was highly significant (p<0.001). The regression coefficients for Max THI for the variables pregnancy rate and conception rate were significant (p<0.0001). With every increasing unit of Max THI, a 0.84% drop of the pregnancy rate, and a drop of 1.74% of the conception rate was estimated by the model. The regression coefficient of Max THI for the service rate variable was not significant.
Conclusion: It was concluded that the increase of the Max THI significantly affected the reproductive performance of intensive dairy cattle farms in Lima.

DFT modelling studies of spectroscopic properties and Medium Effects on Molecular Reactivity of Secnidazole in different solvents
Authors: HSSAIN Ala
Published: June 2022

The spectroscopic and optoelectronic investigations of (hydroxyl-2-propyl)-1-methyl-2-nitro-5-imidazole (secnidazole, C_7 H_11 N_3 O_3) molecule were performed using C13 and H1 NMR chemical shifts, FT-IR spectroscopies. Molecular geometric optimizations, HOMO-LUMO properties and molecular electrostatic potential (MPE) were studied using B3LYP functional in DFT method at the cc-pVDZ basis set. UV-Vis spectra of the titled molecule in several solvents (water, dimethyl sulfoxide (DMSO), nitromethane, acetone, and tetrahydrofuran (THF) were investigated theoretically with the aforementioned model method. The solvents have an effective role in the optoelectronic properties of the secnidazole molecule. From non-polar to polar solvents, the (HOMO and LUMO) bandgap energy of secnidazole was found to be decreased except THF solvent. Furthermore, the research aims at investigating the medium effects on solvation free energy, polarizability, dipole moment, first-order hyper-polarizability as well as several molecular properties such as chemical potential, electronegativity, chemical hardness and softness, electrophilicity index of secnidazole (SNZ). The aforementioned method and basis set was used for all kinds of computations in the gas phase and solution. The Solvation Model on Density (SMD) was applied to the aforementioned solvent systems to calculate the solvent polarity effect on dipole moment, free energy, and molecular properties of the (SNZ) molecule. The free energies have gradually increased with a decrease in the solvent dielectric constant i.e. as solvent polarity decreases, the solvation energy increases. From polar to non-polar solvents, the dipole moment of secnidazole was found to be decreased. In various solvents, the dipole moment of secnidazole was greater than that of the gas phase. With the decrease of the solvent dielectric constant, the first-order hyperpolarizability and polarizability have also been decreased. Besides, electronegativity, the chemical potential, and electrophilicity index were decreased continuously from polar to non-polar solvent, except in THF. Secnidazole’s electronegativity, chemical potential, and electrophilicity index were higher in THF than in acetone. However, with increasing solvent polarity, chemical hardness decreased and the inverse relationship was noticed in the case of chemical softness. The obtaining results in this computational investigation may lead to a better understanding of the stability and reactivity of secnidazole and will be helpful for the use of the title compound as reaction intermediates and pharmaceuticals.

This study was synthesized: 1-(4-(3-methyl-3-phenylcyclobutyl)thiazol-2-yl)-3-phenylthiourea and 1-(4-chlorophenyl)-3-(4-(3-methyl-3-phenylcyclobutyl)thiazol-2-yl)thiourea. Fourier-Transform Infrared (FT-IR) spectroscopy and Nuclear Magnetic Resonance (NMR) were used to characterize the molecular formula. Theoretical vibration was computed with Gaussian 09W software, and corrosion inhibiting activity was computed with quantum chemical calculations. Furthermore, the GaussView 5.0 package was used on the B3LYP/6-311G(d,p) method to calculate the energy of the highest occupied molecular orbital (EHOMO), the energy of the lower occupied molecular orbital, energy gap (ΔE = ELUMO - EHOMO), the dipole moment (µ), and the percent of transmitted electrons (ΔN). Other molecular properties such as hardness (ɳ), softness (σ), and electronegativity (χ) were calculated based on the results of inhibitor activity. The corrosion inhibiting activities of the derivatives were predicted using quantum chemical calculations. As a result, the corrosion inhibitor behavior can be predicted without the need for an experimental study. The results show a strong relationship between organic-based corrosion inhibitors and the process's quantum chemical parameters.

Промени в методологията за изследване на съвременното изкуство на Украйна: представяне на женствеността
Authors: Lutsyshyna Dariia
Published: June 2022

The article discusses the shift from the methodology of the Soviet totalitarian period in Ukrainian art history to the modern methods that are more appropriate for the interpretation of contemporary Ukrainian art. The analysis showed that, during the Soviet period, art and art history in Ukraine were under strict ideological and political control. Art history and criticism were widely used as a means of ideological propaganda, and therefore art studies could not fully represent and interpret art. A considerable part of the art phenomena was ignored by researchers due to the hierarchy of trends and genres of art established in the USSR; art historians had to assess the “validity” of an artwork or an artist according to the official ideology. The variety of methods and research instruments was limited and insufficient for the research of contemporary Ukrainian art, including feminist art. The creative work of the Ukrainian female artist Alina Kopytsa is shown as an example in order to demonstrate the expedience of modern approaches, which are still not common for Ukrainian art history. Thus, a wider range of methods and approaches is regarded as the means to develop an effective methodological background, and to provide a better understanding of contemporary Ukrainian art.
A Contemporary Atomistic Model of Art. Part One
Authors: Totlyakov Atanas
Published: June 2022

The article discusses basic theoretical formulations through which the possibility for conceptualizing a new model of art is outlined. The new model is discussed as atomistic or as a model that comes to the active division of the whole into discrete parts, their definition and interactions. The study defines the differences between the modern atomistic model in terms of both holism and classical atomism. The desired model represents an ontogenetic process of creating, communicating and accepting the work of art in the environment that surrounds us and that is within us.
Morphology of the Contemporary Sacred Space. Sacred Spaces During a Pandemic
Authors: Sarbova Adriana
Published: June 2022

The COVID-19 pandemic has undoubtedly been the main theme in the last two years (2020–2021). Different kinds of restrictions affected almost all social processes. But apart from the negative effects, the pandemic was the reason for a slowdown in the lifestyle of most people. The halt in the constant traffic and tourism reduced pollution in the cities, and for the first time in a long period, the blue sky could be seen above cosmopolitan cities. Wild animals appeared in urban places. Nature seemed to recover from the harmful impact of man. My observations also show different kinds of change in people’s life related to rediscovering forgotten values and the need for a new kind of spirituality. The social restrictions shifte people’s attention towards their inner self. This article presents two architectural spaces in the wide frame of the revised term contemporary sacred space. The goal of the study is to reveal specific characteristics of sacred spaces, created during the pandemic, and how this extreme situation outlined the new (or rather well forgotten) values and spiritual searches of society, shaping the model of the contemporary temple.
Public Reprimand in the Context of Bulgarian Criminal Law
Authors: Yordanova Tina
Published: June 2022

The subject of this article is the study of the role, meaning and place of the punishment called “public reprimand” in Bulgarian criminal law, particularly in the Criminal Code. The paper studies the nature and content of public reprimand as a type of punishment, and traces, albeit more generally, its development in Bulgarian criminal law, taking into account its importance relevant to previous periods. The regulation of public reprimand in criminal law, specifically its place in the system of penalties under the Criminal Code, is clarified, mentioning individual criminal cases in which public reprimand is intended to be imposed. In addition, a comparative legal analysis is carried out, on the basis of which separate observations are made regarding the regulation of public reprimand, and examples of foreign criminal laws are summarized. At the same time, the article raises specific questions about the effectiveness of public reprimand as a type of punishment used in the fight against crime, drawing specific conclusions about the extent to which public reprimand actually achieves the objectives of punishment in the Penal Code. The moral character of public reprimand is also touched upon, and the possibility is discussed, respectively the lack of such, when using it as a punishment in order to observe one of the most important criminal law principles which all types of punishment under Bulgarian criminal law rely on – the correspondence between punishment and crime. A new approach to the settlement of public reprimand is proposed, aimed at its elimination as a type of punishment from the system of punishments under the Bulgarian Penal Code.

The climatic dynamics of temperature and humidity in the region of Kazakhstan Altai and its influence on the runoff of the Irtysh (Ertys) river are considered. It is shown that climatic changes in the region generally reflect such changes in the territory of Kazakhstan, however, there are a number of features, consisting in the degree of severity of extremes and some of their delay in relation to central Kazakhstan. Surface runoff follows the dynamics of precipitation and temperature in the area of its formation. The time course of the runoff in the upper and middle reaches of the Irtysh is significantly different, which is the result of the influence of economic activity, as a result of which part of it is irretrievably taken. It has proven difficult to quantify runoff loss. A forecast is made of expected changes in runoff under the influence of climate change.

manage their own learning. The self-regulated learning practices of goal setting, environment structuring, task strategies, self-evaluation, time management, and help seeking are developed through experience and motivation. This study sought to determine the levels of self-regulated learning and identify the motivation constructs that correlated to the levels of self-regulated learning of students in an online agriculture dual enrollment course. Students had the highest self-regulation in the areas of goal setting and environment structuring. The lowest online learning self-regulation was in help seeking. Task value was the motivation construct receiving the highest mean score, while test anxiety received the lowest score. Relationships between online self-regulated learning and the motivation constructs of task value, self-efficacy, intrinsic motivation, extrinsic motivation, control beliefs, and test anxiety were statistically significant. Faculty in online courses are encouraged to aid in the development of help seeking, time management, and meta-analysis strategies. Faculty are also encouraged to incorporate valuable tasks within the online curriculum to increase students’ motivation to learn. Course developers are encouraged to incorporate problem-based learning, authentic assessments, and team-based learning approaches to better engage students. Research should continue to investigate these practices as they relate to increasing student motivation.
Bringing Work-Life Balance to Extension
Authors: Patel Dhruti
Published: June 2022

Throughout its one hundred plus years of history, the Cooperative Extension System has experienced many changes. Since its beginning, the Extension System has revolutionized nonformal educational approaches and outreach methods. However, these changes have also created issues such as role ambiguity, work-life conflict, work-life spillover, burnout, stress, and work-life imbalance among Extension professionals. There are very few currently existing publications that identify present day work-life balance issues in Extension. Most of such information is dated and irrelevant to current workings of Extension. To give more in-depth insights on this subject, a number of well-established theories, such as compensation, spillover, inter-role conflict, and role enhancement theories, are discussed in this publication. These theories are selected based on their relatability with Extension. Hence, this article was created with an intent to encourage a dialogue concerning current work-life balance issues within Extension. The article also illustrates a conceptual theoretical perspective–a three-tier approach to work-life balance in Extension. This approach discusses elements, such as individual awareness, environmental factors, and organizational policies, to inculcate positive work-life balance practices. This proposed approach could be a guide to creating a more positive work culture, improving work-life satisfaction among Extension employees, and boosting organizational competence and productivity.

Published: June 2022

Chronic diseases are strongly associated with premature death and increased health care costs. Nearly half of American adults report they have one or more chronic health conditions. Cooperative Extension is calling for refocus to refine and align with broader efforts to promote public health by supporting the prevention and management of chronic disease. The success of this refocus is dependent on a shared vision between funding agencies, stakeholders, and Extension. As part of developing this shared vision, the Chronic Disease Health Implementation Team surveyed 152 Extension administrators, faculty, and Extension Agents/Educators to determine their perception of the role of Extension in chronic disease prevention and management in the next century. Respondents answered the open-ended question, “What role should Cooperative Extension have in working to reduce chronic diseases in America for the next 10, 25, and 100 years?" Analysis with grounded theory identified three themes. The respondents perceived the role of Extension professionals as educators and collaborators in chronic disease prevention and management who focus on influencing individuals and environments. As educators, Extension should deliver evidence-based programs to communicate, inform, facilitate, and teach. As collaborators, Extension should facilitate and nurture partnerships to effect changes in chronic disease prevention and management.

Published: June 2022

This study examined the six-year bachelor’s degree graduation status of freshmen (N = 1,839) entering the Dale Bumpers College of Agricultural, Food and Life Sciences (AFLS) between 2001 and 2010. The overall graduation rate was 64%, including 23% who had transferred out of AFLS. Multinomial logistic regression was used to determine if student entry data differentiated between graduates and non-graduates and between AFLS and non-AFLS graduates. High school GPA (HSGPA), first-generation status, and year of admission to the university significantly differentiated between graduates and non-graduates. Each standard deviation increase in HSGPA was associated with a 224% increase in the relative odds of graduating. Students entering each subsequent year had a 10% increase in the relative odds of graduating. Being a first-generation student decreased the relative odds of graduating by 52%. Year, major, and composite ACT score (CACT) significantly differentiated between AFLS and non-AFLS graduates. Students entering each subsequent year had a 16% increase in the relative odds of being AFLS graduates, while agriculture majors were about twice as likely to be AFLS graduates. Each standard deviation increase in CACT score was associated with a 26% decrease in the relative odds of being an AFLS graduate.

Bu çalışmanın amacı Osmanlı Devleti’nin son döneminde ve Türkiye Cumhuriyetinde öğretmen yetiştirme ve bu konuda Orta Asya Türk dünyası ile ilişkileri tarihi süreç içinde incelemek ve gelecekte daha yapılandırılmış işbirliği için öneriler geliştirmektir. Osmanlı Devletinin ve Türkiye Cumhıriyetinin Orta Asya ve Rusya’daki Türklerle olan ilişkisi coğrafi uzaklık ve siyasi nedenlerle oldukça sınırlı kaldığı için bu durum eğitim ve öğretmen yetiştirme alanına da yansımıştır. Osmanlının Tanzimat’tan beri Batıya yönelmesi de kültürel bir etmen ve dünya görüşü olarak Osmanlı Devletinin Orta Asya ve Rusya Türklerine olan ilgisini olumsuz etkilemiştir. Bu durum Türkiye Cumhuriyeti Devletinde de 1991’e kadar gözlenmektedir. Osmanlı Devleti ve Türkiye Cumhuriyeti Devletinin Rusya ve Orta Asya Türk Dünyasına eğitim katkıları arasında oralara öğretmen gönderme çalışmaları dikkat çekmektedir. Orta Asya’da 1991’den sonra kurulan yeni Türk Devletleri ile Türkiye Cumhuriyeti Devleti arasında eğitim ve öğretmen konularında her geçen gün ilişkiler gelişmektedir. Bu ilişkilerin daha çok güçlenmesi için; yapılandırılmış, akılcı ve özgün modeller geliştirmek, Türk devletlerinin ve akraba toplulukların geleceği açısından büyük önem arz eden bir konu olarak düşünülmelidir.
