Published: March 2023

Incommensurability plays a critical role in many strongly correlated
systems. In some cases, the origin of such exotic order can be
theoretically understood in the framework of 1d line-like topological
excitations known as “quantum strings”. Here we study an extended
transverse field Ising model on a triangular lattice. Using large-scale
quantum Monte Carlo simulations, we find that the spatial anisotropy can
stabilize an incommensurate phase out of the commensurate clock order.
Our results for the structure factor and the string density exhibit a
linear relationship between incommensurate ordering wave vector and the
density of quantum strings, which is reminiscent of hole density in
under-doped cuprate superconductors. When introducing the
next-nearest-neighbor interaction, we observe a quantum tricritical
point out of the incommensurate phase. After carefully analyzing the
ground state energies within different string topological sectors, we
conclude that this tricriticality is non-trivially caused by effective
long-range inter-string interactions with two competing terms following
different decaying behaviors.

How well mental health workers are motivated: A case study from Croatia
Authors: Goncharuk Anatoliy , Knezevic Bojana , Marcinko Darko
Published: March 2023

Like the other medical professions, mental health workers need appropriate motivation for effective treatment work. This study aims to determine the motivators and assess working conditions of mental health workers and how they differ from the motivators and working conditions of other health workers on the example of one of the largest hospital institutions in Croatia – University Hospital Centre Zagreb. The study chose a survey method and distributed a questionnaire among 124 Zagreb University Hospital Centre health workers. The sample covers about 16% of the entire medical staff of the observed departments (psychiatry, emergency, microbiology, gynecology, anesthesiology, COVID-19 unit, and orthopedic surgery). The ANOVA method was used to detect differences in data groups. The results show that Croatian mental health workers are mainly motivated extrinsically. However, compared to other medical professions, e.g., gynecologists, orthopedists, or anesthesiologists, they are upper-middle motivated and leaders in several motivators. Observed Croatian mental health workers are more satisfied with their patient interactions than their colleagues. Female mental health workers are more motivated but less satisfied with the working conditions than males. The study showed that even in one medical institution, there are significant differences in the needs of representatives of different professions. The paper concludes that mental health workers have different motivations, which can be satisfied by creating appropriate working conditions.

TÜRKİYE’DE ÇALIŞAN KADINLARIN KÜÇÜK ÇOCUKLARINA KİM BAKIYOR?
Authors: UGUR Zeynep , YILDIZ Emre , YÜKSEL DOĞAN Raziye
Published: March 2023

Türkiye’nin kalkınma planlarında ve çeşitli uluslararası kuruluşlar tarafından küçük çocukların erken çocukluk döneminde kayıtlı bakım hizmeti almasının gerekliliği; kadın istihdamının arttırılması, ebeveynlerin iş-yaşam dengesinin sağlanması ve çocukların daha nitelikli erken çocukluk eğitimi alması gibi amaçlarla vurgulanmaktadır. Bu araştırmanın amacı Türkiye’deki çocuk bakım alternatiflerinin ebeveynler tarafından tercihini etkileyen faktörlerin belirlenmesi, özellikle kurumsal bakım ve evde çocuk bakım hizmetleri yoluyla bakılan çocukların oranlarının zaman içinde nasıl bir değişim gösterdiğinin incelenmesidir. Bu amaçla, çalışmada Türkiye’de yaşayan kadınları temsil eden bir örnekleme sahip olan Türkiye Nüfus ve Sağlık araştırmasının 2003-2018 yılları arasında yapılmış 4 dalgasının fert düzeyindeki verileri kullanılmıştır. Çocuk bakım tercihlerini açıklamak için çok kategorili lojit regresyon modeli kullanılmıştır. Araştırma sonuçları çalışan annelerin çocuk bakımını kabaca (~%60) 3 kadının sağladığını göstermektedir. Bunlar; anne, anneanne ve babaannedir. Mevcut çalışmanın sonuçları kreşler ve anaokullarında sağlanan kurumsal bakımın, çalışan kadınların çoğunluğu tarafından tercih edilmediği veya edilemediğini göstermektedir. 2018 yılı itibariyle 0-5 yaş arası çocuğa sahip olan çalışan kadınların sadece %12’sinin kurumsal bakımı tercih ettikleri görülmektedir. Bununla birlikte zaman içinde kurumsal bakımın tercih edilme oranlarında artış olduğu da dikkat çekmektedir. Kurumsal bakım tercih olasılığını artıran faktörler çocuğun yaşı, ailenin ekonomik durumu ve annenin eğitim düzeyidir. Annenin ücretsiz aile işçisi olarak çalışması ve hanedeki toplam birey sayısı kurumsal bakım tercihini olumsuz yönde etkilemektedir. Bu faktörler regresyon modelinde hesaba katıldığında bölgelerin katsayıları büyük ölçüde istatistiksel olarak anlamsız hale gelmiştir. Bu sonuç kurumsal bakım tercihlerinin bölgeler arasındaki kültürel farklılıklar ile açıklanamayacağını; bakım tercihini belirleyen unsurların annenin ekonomik kaynakları ve eğitimi ile ilişkilendirilebileceğini düşündürmektedir
Interactive Medical Calendar as a Genre of Internet Communication: Russian as a Foreign Language
Authors: Dreyfel'd Oksana
Published: March 2023

This paper describes the linguo-didactic prospects of using the method of interactive medical calendar to develop an artificial language environment for students who study Russian as a foreign language. It features classifications of medical calendars, their receptive properties, and experience of using them as a linguo-didactic genre in teaching Russian. The authors designed an interactive medical calendar that develops a professional medical jargon in non-Russian speakers at medical institutes. The method proved to be an efficient multimedia tool that unites the realities of medicine and language learning in a new context. It promotes learning by doing and out-of-class practice. The calendar allows non-Russian speakers to use professional terms and activates theoretical knowledge while developing digital skills. It also improves the skill of cross-cultural contacts, encourages informal communication, individualizes the learning process, and increases motivation in mastering both the medical profession and the Russian language. The method of medical calendar is a simple genre that facilitates the academic process of learning Russian as a foreign language by adding new activities and information.

Authors: Chepkasov Artur
Published: March 2023

The cross-media interaction between the Kemerovo State University and the regional authorities in social networks can be analyzed as a method of PR-promotion. A content analysis of Telegram channels proved that the PR-structure of the Kemerovo State University applies this method quite successfully. According to Gary Hayes, this method works at two levels of Crossmedia 1.0 – Pushed and Crossmedia 3.0 – Bridges. The analysis revealed a direct communication between the university Telegram channel and the channel sponsored by the Ministry of Science and Higher Education that covers all Russian universities. Such content creates and promotes the image and brand of the Kemerovo State University, as well as increases its publicity capital and that of the regional authorities represented by Governor Sergei Tsivilev.

Published: March 2023

Background:

Concurrent or definitive chemoradiotherapy is the standard treatment of locally
advanced esophageal squamous cell carcinoma (ESCC). Elderly patients could not tolerate the
standard concurrent chemotherapy and were treated with radiotherapy because of weak physical status
and multiple comorbidities.

Objective:

The efficacy and safety profile of concurrent (chemo) radiotherapy combined with
nimotuzumab in elderly patients with ESCC were investigated.

Methods:

Eligible elderly (≥70 years) patients with locally advanced ESCC were enrolled in this prospective,
real-world pragmatic study and received concurrent chemoradiotherapy or radiotherapy
combined with nimotuzumab. The primary endpoint was overall survival (OS). Secondary endpoints
were objective response rate, disease control rate, progression-free survival (PFS), and adverse drug
reactions.

Results:

Fifty-three elderly patients were enrolled. Thirty-two (60.4%) were treated with radiotherapy
combined with nimotuzumab (RT+N), and 21 (39.6%) with concurrent chemoradiotherapy combined
with nimotuzumab (CRT+N). The median age was 75.8 years. Fourteen (56.0%) patients achieved a
partial response, and 11 (44.0%) patients achieved stable disease at 3 months. The median follow-up
duration was 24.4 (95%CI, 21.6-26.7) months. Median OS (mOS) was 27.0 (95%CI, 14.8-48.4)
months. Median PFS (mPFS) was 22.6 (95%CI, 12.4-not reached) months. Higher mPFS (not reached
vs. 12.0 months; p=0.022) and mOS (48.4 vs. 15.3 months; p=0.009) were observed in the CRT+N
group compared with the RT+N group. Most adverse reactions were grade 1-2 (46, 86.8%).

Conclusions:

Concurrent chemoradiotherapy or radiotherapy combined with nimotuzumab was safe
and well-tolerated in elderly patients with locally advanced ESCC. ESCC patients treated with
CRT+N could live longer.

Authors: Fekri Mitra Samareh , Bajgani Seyed Mehdi Hashemi , Shafiepour Mohsen , Yazdani Reza , Dalfardi Behnam
Published: March 2023

Introduction::

Bronchial asthma is a chronic disorder with high prevalence among wom-en. Visfatin as a pro-inflammatory adipokine has been linked to inflammatory lung diseases such as asthma and can be used as a forthcoming biomarker target to diagnose and treat asthmatic patients.

Aim::

The aim of this study is to evaluate plasma visfatin level and its correlation with pulmonary function of female asthmatic patients.

Methods:

This cross-sectional study was conducted on all female asthmatic patients referred to the Be'sat Pulmonary Clinic of Kerman from 1 November 2019 to 20 February 2020. Patients with con-firmed diagnosis of asthma were included. The data were collected through a checklist and the cor-responding author conducted all face-to-face interviews in the physician’s office of the pulmonary clinic. Then, blood samples (5 cc) were taken from the patients to determine the plasma level of visfatin. Data was analyzed by SPSS Software.

Results:

113 women with asthma were studied. The mean ± SD age of patients was 46.71 ± 13.91 years (range: 13 to 75). The mean ± SD of visfatin plasma levels was 26.30 ± 6.98 mg/dl (range: 8.50 to 46.88). The forced expiratory volume in the first second (FEV1) had a significant and negative correlation with plasma visfatin concentrations (P-value = 0.03).

Conclusion:

The results of this study indicated that plasma visfatin levels were correlated inversely with FEV1 among asthmatic women. Further studies with large samples are recommended to evaluate the role of visfatin in asthma pathogenesis.
Clinical and Radiographic Evaluation of Combined Acemannan and Periodontal Surgery Induced-Periodontal Regeneration: 5-Year Follow-up Case Report
Authors: Chansamart Rutchanoo , Sangvanich Polkit , Thunyakitpisal Pasutha
Published: March 2023

Background and Objective:

Acemannan, a polysaccharide extracted from aloe vera gel, accelerates oral wound healing, reparative dentin formation, and bone formation in extraction sockets. In this report, we evaluated the efficacy of combined acemannan and periodontal surgery on periodontal regeneration in severe periodontitis cases requiring periodontal surgery.

Case Presentation and Discussion:

Three chronic periodontitis patients with probing pocket depths of at least 6 mm and two- or three-walled vertical bone defects after initial periodontal therapy were included. The patients underwent minimally invasive periodontal surgery with acemannan sponges placed in the defect. Maintenance recall was scheduled every 6 months for 5 years. Clinical and radiographic evaluations were performed to assess the effects of the combined acemannan and periodontal surgery on periodontal regeneration. The patients demonstrated improved clinical parameters and increased radiographic bone fill at the 5-year follow-ups. The percentage bone fill in the three-walled defect, combined two- and three-walled defect, and two-walled defect cases were 70%, 60%, and 20%, respectively. The underlying mechanism of action of acemannan in periodontal regeneration was also discussed.

Conclusion:

Acemannan sponges can be used as an adjunct to periodontal surgery for periodontal regeneration.

Published: March 2023

The purpose of this research is to learn about the attitudes of the academic staff of the medical, business, humanities, and science and engineering disciplines concerning online education during the COVID-19 pandemic at Umm Al-Qura University (UQU), Saudi Arabia. While research in online education focuses on learning experiences such as facilities, learning materials, and learning interests, several elements of online education in this research were investigated, including advantages, features, and cybersecurity. The research data were gathered through a survey containing three demographic items, four items on perceptions of online education, and seven questions on perceptions of cybersecurity. Responses obtained from 238 academic staff were used for statistical analysis. After the routine descriptive analysis analyses, the response data were subjected to unsupervised k-means centroid cluster analysis. Two clusters of academic staff differing in teaching disciplines, and pre-COVID experience in online education were identified. Cluster 1 had medical and business and humanities academic staff, predominated by those without pre-COVID experience in online education, and perceived online education and cybersecurity at neutral to a slightly low level. Cluster 2 consisted of science and engineering discipline academic staff predominated by those with pre-COVID online education experience and perceived online education and cybersecurity in the range of neutral to slightly high levels. The result of this study shows that academic staff in the medical, business, and humanities disciplines have less expertise with online education software and a low level of awareness about online education security. On the other hand, academic staff of science and engineering disciplines fields has more expertise with online educational technologies and a better level of understanding of online education security.

The first results of the electrons drift velocity study in inverted AlGaAs/InGaAs/GaAs pseudomorphic heterostructures with donor-acceptor doping and short-period AlAs/GaAs superlattices are presented. It is theoretically shown that the introduction of superlattices significantly, up to one and a half times, increases the electrons drift velocity overshot when they enter the region of a strong field. Localized states in the superlattice between the quantum well and the substrate have been found. It is shown that this effect leads to an additional increase in the electrons drift velocity overshot up to the theoretical limit for the model used, i. e., a drift velocity overshot in the bulk material of the quantum well. Keywords: inverted heterostructure, digital barriers, field-effect transistor, gain.

Comparison of Household Environmental Factors among Children with Reported Asthma and Controls
Authors: Sousa Joana
Published: March 2023

The present research was part of a cross-sectional project involving children aged 8 to 10 years in Porto, Portugal. The project involved a first research part at primary schools where the health tests and a questionnaire were performed and a second research part concerning environmental conditions. Two groups emerged from the health questionnaire answers: one group that reported “asthma diagnosed by a doctor” and/or “wheezing or whistling in the chest during last 12 months” and another that answered negatively to both questions. After performing the health questionnaire based on ISAAC, the children responsible were invited to participate in the environmental part of the study. The outdoor and indoor potential risk factors were extensively evaluated in children's homes. This research aimed to compare housing characteristics and indoor behaviours as environmental risk factors in the two children group and investigate whether the risks found are common. The results indicate that windows open during cleaning, standard window frame material, animals at present, dog presence, cat presence, sweep, and vacuumed floor cleaning were associated with both groups. This demonstrates that home characteristics influence some risks and may be exacerbated by certain occupants' behaviours.

Susceptibility of Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) Collected from Central Java Province to Emamectin Benzoate, Chlorantraniliprole, and Spinetoram
Authors: Suryani Julia Nanda , Trisyono Y. Andi , Martono Edhi
Published: March 2023

Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is a new pest on maize that has successfully spread to various regions in Indonesia. This pest can cause severe damage to the affected plants. Most farmers have relied on synthetic insecticides for control. This research was conducted to determine susceptibility level of S. frugiperda larvae to emamectin benzoate, chlorantraniliprole, and spinetoram insecticides by using the diet-dipping method. There is no registered insecticide to control S. frugiperda, so the three types of insecticides used were based on the recommendation of the Ministry of Agriculture of the Republic of Indonesia. Five field-collected population from Central Java and a laboratory populations of S. frugiperda were used to develop a baseline susceptibility for each insecticide. First instar larvae of S. frugiperda were placed in vials containing artificial diet treated with insecticides and an untreated control (treated with water only), observed for mortality on the seventh day and data was analyzed using probit. S. frugiperda from Tegowanu was the most susceptible to emamectin benzoate (LC50 = 0.11 mg/L), while the least susceptible population was from Wedi (LC50 = 0.39 mg/L) with the resistance ratio (RR) values of 0.45-folds and 1.60-folds compared to the laboratory population, respectively. S. frugiperda from Ngombol was the most susceptible population to chlorantraniliprole (LC50 = 12.63 mg/L), while the least susceptible population was from Tegowanu (LC50 = 30.29 mg/L) with RR values of 0.90- and 2.15-fold compared to the laboratory population, respectively. Meanwhile, S. frugiperda from Jogonalan was the most susceptible to spinetoram (LC50 = 2.75 mg/L), while the population from Wedi was the least susceptible (LC50 = 5.94 mg/L) with the RR values of 0.52- and 1.12-fold compared to the laboratory population. Field-collected S. frugiperda populations were still susceptible to the three tested insecticides tested and emamectin benzoate being the most toxic compared to spinetoram and chlorantraniliprole.

Published: March 2023

Heritage trees are long-lived trees or notable trees with great historical significance, scientific value, or commemorative importance. Many heritage trees have been preserved in Weifang City, Shandong Province, Northern China. In this paper, the origin, species diversity, age structure, health, surrounding habitats, distribution, genera floristic composition, and challenges of protecting the heritage trees were investigated using literature analysis, field survey, and interview. There are 864 heritage trees in the city, composed of 49 species, 41 genera, and 25 families. The heritage trees are divided into three original types: religious trees, naturally dispersed and preserved wild trees, and trees with agricultural backgrounds or used as offerings. Particularly, Sophora japonica, Ziziphus jujube, Ginkgo biloba, Sabina chinensis, Platycladus orientalis, and Osmanthus fragrans are the six most common species. There are 208 individuals of 500 years or elder, 293 individuals of 300–499 years old, 359 individuals of 100–299 years old, and 4 individuals of notable trees. Most of them are distributed in low-urbanized areas of the 4 county-level cities and Linqu county, and few are distributed in high-urbanized areas of the 4 districts of Weifang City. There are 14, 12, and 6 genera belonging to the areal-types of Temperate, Cosmopolitan, and Tropic, respectively, similar to that of wild seed plants in Yishan Mountain. There are some challenges in protecting heritage trees, such as urbanization, habitat deterioration, natural disasters, anthropic activities, health decline, and inadequate management. Some protection measures that have been taken previously are summarized, and some measures that should be taken in the future are proposed.

Abstract: Crypto currency is the latest and the most significant development in the financial industry. It has brought a revolution in the Indian financial markets and created a challenge for the banking industry by presenting it as investment opportunity. Bit coin, the first and the most popular crypto currency launched in the year 2009. It has given the other option to the long standing and unchanged financial payment system which is existing for many decades. It is a decentralized digital currency that can be sent from user to user on the peer-to-peer. In the bitcoin network it can be sent without the need for intermediaries, where transactions are done through a public ledger called block chain, where user data is stored anonymously. It has created a robust digital trade markets where there is free flowing trading system without fees. They are not going to replace the traditional system of payments but they have changed the way of making payments through internet and interaction of global markets. In addition to this has given an investment option too. In the light of above facts current research has been conducted to know the status of cryptocurrency in India, various types of crypto currencies existing in India its problems and prospects. It was found that there is no legal regulation to control their operation only current announcement in the budget gains arising from the trading of these currencies has brought under taxation. But till date RBI has not given any recognition to it and the user /investor is responsible for their risk.
A mathematical framework for operational fine tunings
Authors: Catani Lorenzo , Leifer Matthew
Published: March 2023

In the framework of ontological models, the inherently nonclassical features of quantum theory always seem to involve properties that are fine tuned, i.e. properties that hold at the operational level but break at the ontological level. Their appearance at the operational level is due to unexplained special choices of the ontological parameters, which is what we mean by a fine tuning. Famous examples of such features are contextuality and nonlocality. In this article, we develop a theory-independent mathematical framework for characterizing operational fine tunings. These are distinct from causal fine tunings – already introduced by Wood and Spekkens in [NJP,17 033002(2015)] – as the definition of an operational fine tuning does not involve any assumptions about the underlying causal structure. We show how known examples of operational fine tunings, such as Spekkens' generalized contextuality, violation of parameter independence in Bell experiment, and ontological time asymmetry, fit into our framework. We discuss the possibility of finding new fine tunings and we use the framework to shed new light on the relation between nonlocality and generalized contextuality. Although nonlocality has often been argued to be a form of contextuality, this is only true when nonlocality consists of a violation of parameter independence. We formulate our framework also in the language of category theory using the concept of functors.
Gender issues in Confucian ethics in contemporary Vietnam
Authors: Nizhnikov S. A. , Pham Tien Bac
Published: March 2023

Confucianism like Taoism is a part of the treasury of the world spiritual culture as created by the “axial age” (K. Jaspers); however, time affects even the most humanistic teachings, many of the provisions of which can be formalized, become obsolete, requiring both a “return to the origins” and clarification or reinterpretation and renewal. These processes of both positive and negative nature affected the norms of Confucian ethics in Vietnam. The article aims at examining the gender content of the Vietnamese Confucian ideals and their impact on the contemporary Vietnamese society. Confucian ethics was introduced in Vietnam during the Chinese colonization and had a great influence on both feudalism in general and on the social perception of the woman and her position in the family, determining gender roles and corresponding gender stereotypes for a millennium. The article identifies both general and special features of the gender issues in the Chinese and Vietnamese traditional Confucian ethics. In addition to many negative aspects (such as restraining women’s personal development and limiting their participation in feudal ceremonies), the Vietnamese Confucian ethics regarding women was changed for the better, contributing to the humanization of gender relations. Confucian gender principles continue to have both beneficial and detrimental influence on the Vietnamese society today. The study of the distribution and dynamics of changes in gender roles in the traditional and contemporary Vietnamese society can provide empirical data for gender sociology, as it is hard to analyze gender relations without considering national traditions and culture in general.
Social reality in the perspective of temporalism: In search of methodology
Authors: Yarskaya-Smirnova V. N.
Published: March 2023

The article aims at linking social reality with the category of temporality in the conceptual perspective based on some modifications of modernity as culture. The author explains and applies the epistemological means of the temporal turn and presents the agent-subject interpretation of social reality in a new way. The article focuses on the potential of the temporal discourse which is poorly articulated in contemporary works but is immanently inherent in the sociological science. The survey methodology provides variables related to the past and making demands on memory and the ability to reconstruct events, and also projective questions implying the respondent’s ability to extrapolate patterns from the present to the future. The author summarizes the issues of time in her early and recent works and concludes that there is the temporal turn in the studies of social problems, social policy and social reality. The idea of integrating temporality and sociality results in the new components of the proposed analytical approach which emphasizes the agency of the scientific intelligentsia and updates the intellectual-educational and temporal content of the concept and thesaurus of social reality. The relevance and fundamental nature of the proposed approach are determined by the intersection of the temporality of the social life of individuals and groups with the sociological reflection of the fundamental categories and concepts of time in the academic discourse. Post-non-classical reality allows to conceptually explicate the temporality of inclusive-bifurcation sociality which explains institutional and microsocial problems of communities as non-linear worlds. The scientific-practical meaning of the proposed approach is that the concept of temporal social reality results in the study of modifications of value-symbolic and institutional characteristics of the discourse of the scientists’ role as agents of post-non-classical reality.
Our traumatized society: Causes, consequences, and solutions
Authors: Dobrokhotov L. N.
Published: March 2023

The article is a reflection on the monograph by Zh.T. Toshchenko Trauma Society: Between Evolution and Revolution (Theoretical-Empirical Analysis) (Moscow: Ves Mir, 2020. 352 p.). The book analyzes the huge trauma of the Russian state and people after the collapse of the USSR. At the same time, the book identifies those traumas of the past and present that other countries experience under political, economic, social, and often military cataclysms.
The categorical dichotomy Gemeinschaft/Gesellschaft in sociological classics: Tonnies - Weber - Freyer - Parsons
Authors: Kildyushov O. V.
Published: March 2023

The article considers the history of the conceptual pair Gemeinschaft/Gesellschaft (community/society) used by classics of sociology to explain the fundamental difference of modern society from the previous forms of social life. The author emphasizes the popularity of these categories as identifying the temporally successive types of sociality: Gemeinschaft refers to the original form of traditional organic community, and Gesellschaft - to the mass urbanized society of the modern age. The article shows the structural relationship between the early sociological concepts and the philosophy of modern history as an analytical (self)description of modern societies. The article reconstructs the development of Ferdinand Tönnies’ views, who introduced the pair Gemeinschaft/Gesellschaft as an analytical tool for social theory and challenged the opposition of these two types of social integration by emphasizing their presence in every social interaction. The author briefly outlines Max Weber’s perception of this conceptual pair in the form of Vergemeinschaftung/Vergesellschaftung social relations as ideally-typically value-oriented and instrumentally rational. The article explains the drastic politicization of the Gemeinschaft semantics in inter-war Germany - the term became a marker of the social-political polarization. Then the author focuses on the differentiated theory of Gemeinschaft developed in Hans Freyer’s sociology and on the Nazis’ attempt to make this term a basis of their theory of homogeneous society. The article considers the reception of Tönnies’ categories in American sociology, especially by Talcott Parsons, and highlights his contribution to the theory of socialization and integration of large societies with small solidarity groups. The last part of the article emphasizes the significance of the conceptual pair for the theory of late modernity - its structure of social action consists of elements of both community and society.
Efficacy of Ayurveda Interventions in Protein Energy Malnutrition in Children: A Systematic Review and Meta-Analysis

Published: March 2023

According to United Nations International Children's Emergency Fund (UNICEF), in India, around 46 percent of all children below the age of three are too small, and 35.7% are underweight and come under MAM (Moderate Acute Malnutrition). Protein Energy Malnutrition (PEM) can be correlated with Karshya, Balashosha, Phakka, Parigarbhika, Sushka Revati, and Apatarpanjanya Vyadhi based on similar clinical features. Multiple evidencebased clinical studies are conducted in this sector, but no comparative conclusion of results or systemic review is accomplished. The study aims to evaluate and compare Ayurveda interventions' efficacy in managing children's protein energy malnutrition and to assess the effect of Ayurveda Interventions on weight gain and serum protein values in children suffering from PEM. This systemic review was conducted according to the guidelines of the Cochrane Handbook of Systemic review of interventions and is reported following the Preferred Reporting Guideline for Systemic review and meta-analysis guidelines (PRISMA). All study groups showed significant p values within the group and insignificant p values in the fixed random effect model. Though the p-value is insignificant between the groups, one group among the four shows better results in the fixed effect model. In the primary outcome of weight, group 3, i.e., the category of drugs having Bruhana and Pachana combination, shows better results than other groups in the fixed effect model. In the outcome of serum protein values, BMI, and Head circumference, group 4, i.e., drugs with only Bruhana properties, show better results than other groups. Based on this review, few policies or treatment protocols can be hypothesized for managing PEM at the national level. The Ayurveda intervention combinations have worked better because they work on multiple aetiological factors and biological variations in PEM in Children.

The reality is that social welfare services in Nigeria exclude more people than they cover, resulting in the deprivation of basic human needs such as water, sanitation, shelter, healthcare, and education that have hindered the betterment of the living conditions of the citizens (Nkpoyen et al., 2021; Okpa, 2022). This study explored factors affecting the government delivery of social welfare services in Nigeria. Five hundred and seventy (570) respondents’ opinions were purposively sampled using the 36-item Social Welfare Service Delivery Questionnaire (SWSDQ) and an in-depth interview guide. Data were analysed using descriptive statistics, Chi-square statistical technique, and Statistical Package for Social Science (SPSS) software, version 20. As a supplement to the quantitative data, the qualitative data were analysed in themes. Findings from this study revealed that although all the respondents reported knowing about available social welfare services, 44.3% reported not accessing the existing social services because of such factors as political expediency, transparency, accountability, corruption, and perception of social service providers. A key policy issue, therefore, is the need to look into the eradication or mitigation of these factors ascribed to be hindering the delivery of social welfare services. This will expedite the blanket spread of the delivery, accessibility, and utilisation of social welfare services for residents, not just in the study area but across the country
