Background: Vector-borne diseases are a widespread and serious issue that affects populations all over the world and represent a global health challenge. These diseases, like malaria, dengue and chikungunya pose immense challenges due to their rapid transmission and leading to major public health crises during outbreaks. Effective management strategies, including vector control, public health interventions are crucial to curb their impact. The burden of VBDs extends beyond public health, impacting society and economies. These diseases can strain healthcare systems, reduce workforce productivity, and impose significant financial costs. Annually, alarming 700,000 deaths are attributed to vector-borne diseases, underscoring the urgency of addressing this issue. Aim was to assess and evaluate knowledge, attitude and practice towards vector borne diseases in urban area of Bagalkote.
Methods: This is an educational interventional study. This study will be conducted among the urban area of Bagalkote. The study was carried out for 6 months.
Results: In this study among 165 participant’s knowledge of vector borne diseases was quite good. Majority of study subjects were aware about VBD causes death if untreated. Regarding the most frequent mosquito biting period maximum participants 99.39% responded with evening/night time. Almost 95.75% resonance had knowledge, that mosquito bite is the cause of dengue, malaria, chikungunya. The study revealed that majority participants considered dengue, malaria, chikungunya is serious health problem and their attitude vector control measures were positive in almost all study subjects.
Conclusions: The results are very positive and we suggest that people should continue to strengthen their knowledge, attitude and practice towards vector borne diseases. Participants showed adequate awareness towards vector borne diseases.

Authors: Phalswal Uma , Dixit Priyanshi , Verma Ranjana , Rathee Anjali
Published: December 2023

Background: Career by choice means that a student chooses a career of their own choice according to their interests and the demands of time. The present study aimed to investigate the preferences of pursuing government jobs or higher education among final-year nursing undergraduates and perceived barriers to pursuing higher education in nursing.
Methods: A descriptive cross-sectional web-based study was conducted among 207 final-year B.Sc. nursing students from May 2021 to June 2021 at the various All India Institutes of Medical Sciences of India. Data collection was done using total enumerative sampling techniques by self-structured questionnaire. A descriptive statistic was applied to prepare the results.
Results: Findings suggested that the government job after graduation was the priority among students (63.3%), and only (30.4%) of students were highly motivated to pursue higher education in nursing. The majority (42.9%) of respondents given a reason to choose a nursing course were not selected in NEET-UG. Further data revealed that the reason for choosing the job over higher education was financial independence. Findings also reported that the student's perspectives towards the nursing profession were a lack of respect as compared to other medical professions, stigma in society, socially less accepted professions, fewer opportunities in research and education, and gender discrimination in the profession.
Conclusions: The findings necessitate the need for a sensitization program to develop awareness of the benefits of pursuing higher education. This may change the stigma and improve the social image of the profession.

Authors: Gali Kasi V. , Choudhary Anupam , Singh Anshuman , Shah Abhijit
Published: December 2023

Retrieval of high-volume renal stone fragments in percutaneous nephrolithotomy (PCNL) using graspers and baskets can lead to inadvertent renal mucosal trauma and prolonged operative times. We report a case of large right renal pelvic calculus measuring approximately 5.6×4.2×4 cm, which after fragmentation posed a challenge for fragment retrieval to ensure complete stone clearance. We used flush irrigation and suction through a 17 Fr cystoscope sheath inserted into the 30 Fr Amplatz for successful retrieval of the high volume of tiny stone fragments. To our surprise, just after two cycles of flush-irrigation and suction in a duration of approximately 30 seconds, we could achieve complete stone clearance. This technique of utilizing a small caliber cystoscope sheath through a large caliber Amplatz in PCNL could help in selected cases for efficient and safe retrieval of high-volume tiny stone fragments by minimizing renal mucosal trauma, operative times and ensuring complete stone clearance.

Authors: Shamsudeen Faris K.
Published: December 2023

A 61-year-old female patient, presented with complaints of dry cough and gradually worsening dyspnea of 3 months duration, associated with significant weight loss of >14 kg. At presentation, patient was sick, hypoxemic, and tachypneic and system examination revealed fine basal crepitations on auscultation. CT chest showed random pulmonary nodules with bronchiectatic changes. In view of respiratory distress and elevated d-dimer, CT pulmonary angiogram was done and was normal. A contrast echocardiography study hinted towards a significant right to left extracardiac shunt. There was radiological evidence of chronic liver disease with portal hypertension and numerous poorly defined nodular opacities scattered in hepatic and splenic parenchyma in post contrast images. ANA profile was positive for ribosomal-p protein along with elevated serum ACE levels. An ultrasound guided liver biopsy was ultimately performed and histopathology revealed granulomatous lesion in liver compatible with sarcoidosis.
A comparison of mid-upper arm circumference and weight-for-height Z score of world health organization growth standards in detecting moderate and severe acute malnutrition in children aged 6-60 months
Authors: Kanani Siddharth M. , Bharani Sheela N.
Published: December 2023

Background: World health organization (WHO) had defined severe acute malnutrition (SAM) and moderate acute malnutrition (MAM) by weight for height Z score (WHZ) and mid upper arm circumference (MUAC) criteria. Several studies indicate discrepancies in the prevalence of malnutrition on using either WHZ or MUAC. The prevalence of SAM was nearly same when using either criterion and only 40% children showed overlapping by using both the criteria. Present study was taken to identify the overlapping of cases by applying both the WHO criteria in children aged 6-60 months. It also identifies the optimal screening cut off values of MUAC if used as a sole criterion.
Method: It was a hospital based descriptive cross-sectional study done on 640 cases who were assessed for MAM /SAM by using anthropometric WHO criteria.
Results: From 67 SAM cases who were identified by WHZ, only17 cases had SAM on using MUAC too. The sensitivity of MUAC was 25.4% and specificity of 92.0%. From 94 MAM cases, 19 cases showed overlapping by using both the WHO criteria. At MUAC of <13.5 cm, the sensitivity increased to 86.6% for SAM and 81.6% for MAM cases at the cost of decreased specificity which was at around 36% for both the types of malnutrition.
Conclusions: The number of malnourished cases, identified by using either of WHO criteria were nearly same but both these criteria detect different subgroups of malnourished children in most cases. A MUAC of <13.5 cm may be used as a sole-criteria in the community by the health workers to detect acute malnutrition.

Published: December 2023

To evaluate the surgical outcome of use of autologous blood as an adhesive agent in pterygium excision with conjunctival auto-grafting.

To observe the effectiveness of autologous blood adherence on the scleral bed and to know whether autologous blood technique can be made as a standard procedure in pterygium surgery or not.

The present study is a retrospective observational study. The records of 94 cases of primary pterygium surgery done during August 2022- January 2023 were taken. All patients underwent comprehensive ocular examination pertinent to the disease. Pterygium was dissected and remaining subconjunctival pterygium tissue was separated and excised. The conjunctival limbal auto-graft was taken secured in place by autologous blood and dressing done. Follow-up was done on second post operative day,1st week and 1 month.

The study displayed excellent surgical outcome with minimal post operative complications, which too resolved in a week. The most common complication was subconjunctival hemorrhage in 38 cases followed by graft edema in 32 cases. Though graft displacement was observed in 4 cases, they were later rearranged successfully. We did not observe even a single graft loss in our study.

Pterygium excision with conjunctival auto-grafting with autologous blood is very safe, less time consuming, easy to perform with less learning curve, economical with excellent postoperative outcome and most importantly more patient satisfaction, thus, making it equivalent to or rather superior to other comparable procedures.

Published: December 2023

Persistently raised blood pressure not only leads to retinal vascular damage but also leads to systemic diseases. The retinal vasculature observation by fundoscopy offers a great opportunity to explore the association of systemic microvascular disease caused by hypertension. Hypertensive retinopathy (HR) is considered to be a marker for vascular disease and death.

The aim of the present study was to find out the prevalence of hypertensive retinopathy among hypertensive subjects and assess the pattern of retinopathy and associated risk factors.

This was a hospital based cross-sectional study conducted among hypertensive patients at a teaching hospital, for a period of 3 months.

A total of 300 hypertensive patients formed the study population. The prevalence of the hypertensive retinopathy in the present study was 49.33%. Hypertensive retinopathy was more prevalent in men 62% than women 38%. The prevalence of grade 1 and grade 2 hypertensive retinopathies was 43.24% and 33.11% respectively and 20.95% and 2.7% had grade 3 and 4 respectively. The prevalence of retinopathy was found to be statistically higher in patients who had h/o hypertension for more than 5 years. The prevalence of hypertensive retinopathy was more common in age group >60yrs. The prevalence of target organ damage was higher in those having retinopathy.

The prevalence of hypertensive retinopathy is high in the present study which reflects lack of awareness, patient compliance, sub optimal measures to control blood pressure and even lack of prompt follow up with ophthalmologists. There is need to spread awareness and take adequate measures to reduce the burden of hypertensive retinopathy.

Published: December 2023

: Plexiform neurofibroma with neurofibromatosis 1 is a autosomal dominant condition and a relatively rare condition. It is also termed as Von Recklinghausen disease. PN involving the structures like eyelid, orbit, periorbital and facial structures are labelled as orbital-periorbital PN(OPPN). These are slowly progressing lesions and are present since birth but increase in size during childhood and are locally infiltrating in nature.

: To describe a lid incision to simultaneously debulk both upper and lower eyelid, preserving the vascularity in a case of Orbital Periorbital Plexiform Neurofibroma (OPPN).

: We report a case of 22 year male who presented with a disfiguring swelling of right side of face since childhood. After thorough clinical and radiological evaluation it was diagnosed to be a OPPN. Staged debulking was planned and after stage 1 debulking, tissue was sent for HPE which revealed overgrowth of peripheral nerve components and connective tissue dermis showing infiltrating tumour composed of oval to spindle cells with pleomorphic nuclei and moderate cytoplasm. Staged debulking with lid reduction surgery was performed.

: Neurofibroma is a rare entity with plexiform neurofibroma occurring in 5-15% of patients. OPPN infiltrates locally without respecting the anatomical planes but follows the trigeminal nerve distribution usually. Indications for debulking procedure are usually the disfigurement and optimal timing is also not certain because the extent and rate of growth cannot be predicted.

: The facial appearance and outcome in patients with OPPN can be significantly improved through lid reduction surgery.
Sonnet in Stitches: – Patchwork Variations of Modern Religious Sonnets in English
Authors: Wącior Sławomir
Published: December 2023

Across time and geography, the sonnet has served as a vehicle for poets to explore a diverse range of subjects, from personal love and loss, to political and social issues, and to meditate on the human condition itself. This paper will explore the patchwork variations of some modern religious sonnets in English, examining how contemporary poets are using the sonnet form to explore faith, doubt, and spirituality in new and innovative ways. Through an analysis of several representative works, we will demonstrate how these poets are breathing new life into this versatile form, creating works that are both timeless and timely. While many contemporary sonnets depart from the traditional structure of rhyme and meter, they still adhere to a set of self-imposed rules and limitations. This allows poets to experiment with new forms of expression and to explore religious themes in a more relatable and accessible way. Humour, colloquialism, and self-irony are all common features of contemporary religious sonnets, which often depict the sacred in the context of everyday life. Contemporary sonnets attempt to convey the ineffable mystery of religious experience through language, but they are more self-aware of their own structure and the ways in which they depart from tradition. This systematic deconstruction is a significant element of the contemporary sonnet, reflecting the fragmented and chaotic nature of modern existence.

This study aims to describe the status of soil fertility and corn yield on different slopes of agricultural land in UPT SP3 Saritani Village, Boalemo Regency. The study used survey methods at 3 land slope locations (20--30%, 30–40%, and 50–60%), determined purposively. Soil samples and maize yields were analyzed quantitatively and descriptively. Corn yields were collected and compared over 3 harvesting seasons based on the parameters of agronomic components. Soil fertility was analyzed at BSIP PALMA Manado laboratory, with parameters including macronutrient components. An essential finding of this study is that there is a difference in corn yield and nutrients on the sloping lands. The fertility status of farmers' land on the average sloped land of the three stations is very low levels of nitrogen and carbon nutrients and high levels of phosphate and potassium. The agronomic components of Stations 1 and 2 were relatively similar compared to the yield of components at Station 3. In the 3 harvest seasons, Station 1's yield decreased every season; from Station 2 it also decreased, but only at the time of the third harvest, although it was insignificant. The yield from Station 3, the steepest field, decreased significantly.   Keywords: bisi 18 hybrida, maize, sloping land, soil fertility

The use of relatively high doses of inorganic fertilizers to increase yields in plantation-scale pineapple (Ananas comosus) cultivation can lead to new problems, such as being toxic to plants, polluting the environment, and increasing production costs. The utilization of rhizosphere microbes, such as potassium solubilizing bacteria (KSB) is expected can reduce the dose of inorganic K fertilizer application because it can dissolve potassium-fixed Al and Fe soil so that it is available to plants. This study aims to assess and characterize the potential of BPK in pineapple plantation areas. KSB evaluation was carried out based on the Potassium Solubility Index (IKK), besides that, it also carried out the characterization of bacteria that have the potential as CPC isolates. CPC was isolated from planting blocks with low and high production levels in the vegetative (V) and generative (G) phases with 5 replications. As many as 20 isolates from the CPC population on pineapple plantations were successfully isolated in this study. The lowest K solubility index of 0.6 was obtained in isolate RV1 and the highest, namely 1.2 in isolate RG1. Among these isolates, RG1 is Gram-positive and grows optimally at pH 5, temperature 30°C. Based on the results of the phylogenetic analysis, it is known that this potassium solubilizing isolate has the same level of similarity with the bacterium Bacillus subtilis.

The Quiddity of the Imam's Knowledge from Shaikh Mufid and Sayyid Murtaza's Viewpoints
Authors: Chaharborj Mazahir Ahmadian , Chaharborj Mohammad Shokri
Published: December 2023

Imam's knowledge is an important topic in Islamic theology. The knowledge meant by theologians is not the acquired one, rather it is an inner knowledge gained by the Imam in different ways. This knowledge is Ilm-i Ladunni (Inspired Knowledge) and the one that "comes from Allah". Moreover, the Imams' knowledge is Isha'i (intentional knowledge) and is obtained through God's teaching. The content of the hadith "whenever they want, they know" also implies that whenever the Imams intended, they gained knowledge of various affair. They were aware of the affairs. According to hadiths, the Imams obtained some knowledge at once and some gradually. All this knowledge and awareness were related to the Imam's desire and will. In other words, whenever God willed, he would gain knowledge. Of course, this is not in conflict with their knowledge of the time of their own martyrdom; in this case, the Imam was bound to do his duty and had to act according to the Divine will.

Authors: Dmitrikov Vladimir F. , Frid Lev E. , Petrochenko Alexandr Y. , Shushpanov Dmitry V.
Published: December 2023

Background. The use of methods for researching and designing stable nonlinear dynamic systems by constructing the frequency characteristics of the loop gain of the negative feedback of a pulsed voltage converter through time characteristics obtained by numerical methods for solving nonlinear differential equations that describe electromagnetic processes in the converter takes a lot of time and has low accuracy in calculating optimal modes, when you need to calculate hundreds of options.
Aim. Therefore, it seems necessary to further develop the theory of stability of modulation-type pulse voltage converters using frequency stability criteria, Lyapunov functions, amplitude and phase frequency characteristics of the converter loop gain.
Methods. Stability in the «small» is solved using linearized models, which are constructed using the so-called first Lyapunov method - the «first approximation» method. The second method for studying the stability of nonlinear dynamic systems is the harmonic linearization method, when the nonlinear element is replaced by a harmonically linearized link with a transmission coefficient only for the first harmonic.
Results. The Lyapunov function for a pulse voltage converter with nonlinear relay-type elements was found. Conclusion. The results obtained in the work make it possible to simplify the design of Lyapunov-stable pulse voltage converters through the use of the method of amplitude-frequency characteristics used for stationary linear systems.

Published: December 2023

Background. Antenna arrays are widely used in various fields of radio engineering, such as radio and telecommunications, satellite communication systems, etc. One of the important characteristics of an antenna array is its radiation pattern. The estimation of impedance matrices, scattering matrices, and partial radiation patterns is usually performed based on the results of numerical electrodynamic modelling. In the case of a large number of antenna elements, such modelling and optimization of the array requires significant time.
Aim. To investigate the mutual coupling between dual- polarised antenna elements included in a linear antenna array.
Methods. Modelling of antenna arrays based on cross-dipole elements was performed using methods of electrodynamic modelling software. The study of the mutual coupling of antenna elements in the antenna array and verification of the developed mathematical model were carried out by numerical methods.
Results. A physical interpretation of that there is no almost interaction between the elements operating in orthogonal polarizations, and the coefficients of mutual coupling decrease with increasing distance between antenna elements is given. Proposed a simplified model of mutual coupling, which reduces the computational complexity of the problem of determining the mutual coupling matrices.
Conclusion. It is developed a mathematical technique that allows to calculate the characteristics of antenna arrays with a large number of antenna elements, meanwhile electrodynamic modelling is carried out only for an isolated antenna element and a two-element array.
Application of complex-valued convolutional neural networks for equalization and detection of SEFDM systems
Authors: Averina Larisa I. , Kamentsev Oleg K.
Published: December 2023

Background. The disadvantage of spectrally efficient signals with frequency multiplexing is the occurrence of intersymbol interference, which is further aggravated when these signals propagate in frequency selective channels.
Aim. The possibility and effectiveness of using neural network approaches for channel equalization and signal detection in communication systems using SEFDM signals has been assessed.
Methods. A receiver structure for SEFDM systems based on a deep complex-valued convolutional neural network is proposed, which allows recovering bits from the temporal representation of the signal without using the fractional Fourier transform and inverting the cross-correlation matrix between frequency subcarriers. A two-stage network training scheme has been developed. Based on simulation modeling, a comparative analysis of the noise immunity of SEFDM systems was carried out both in a channel with white Gaussian noise and in a channel with Rayleigh fading, using classical and neural network receivers.
Results. It is shown that there is no loss of noise immunity in channels with additive white Gaussian noise and an increase in noise immunity of the system up to 2 dB in the channel specified by the extended automotive model (3GPP-EVA).
Conclusion. The effectiveness of using deep neural complex-valued convolutional networks as receivers for spectrally efficient communication systems, as well as their advantage over classical ones, is shown.
Keywords – SEFDM; deep complex-valued convolutional neural network; turbocoding.
El concepto del enemigo en la guerra de Ucrania

Published: December 2023

El objetivo de esta investigación es analizar cómo medios de la prensa internacional (El País, CNN, Los Ángeles Times, DW y Euro News) reproducen las estrategias lingüístico-discursivas que las elites estadounidenses y sus aliados usan para deslegitimar las acciones y los discursos de sus enemigos como la identidad, las acciones y su discurso. El marco teórico establece que las estrategias lingüístico-discursivas empleadas por las elites gubernamentales y mediáticas en la representación del enemigo son la recontextualización y revalorización del enemigo en sus prácticas y como actor social (VAN LEEUWEN, 1993, 1999). La metodología incluye 60 noticias en orden sincrónico. Las conclusiones demuestran que estos textos son un constructo ideológico articulado para evaluar la legitimidad de las acciones del enemigo-ruso.
THE REINDUSTRIALIZATION OF BRAZIL FROM THE PERSPECTIVE OF FACILITIES MANAGEMENT: CRITICAL REFLECTIONS
Authors: Quinello Robson
Published: December 2023

A free and critical reflection on the process of reindustrialization in Brazil is presented, viewed through the lens of physical infrastructures managed by Facilities Management (FM). Initially, a historical synthesis of the discipline is provided in both academic and practical contexts, illustrating the application of this concept in an industrial setting. The essay is grounded in FM theory, with its roots traced back to Alexander's work from the 1980s, and it aims to discuss its role in artifacts that symbolize industrialization, specifically industrial plants. The discussion unfolds utilizing the life cycle of built spaces as a framework, highlighting the role of FM, which is seldom discussed in the literature, in their location, construction, use, and decommissioning. The objective of the work was to demonstrate the significant and active role of FM in supporting the industrial sector, rather than merely serving as a support area—a stance advocated by Porter in the 1980s.

Grasping for Intraorganizational Power: A Multi-Case Study Analysis of Dysfunctional Functional Behaviours by Information Technology Personnel
Authors: J. Setterstrom Andrew
Published: December 2023

Power plays an important role in organizations. It helps to explain why certain decisions are made and how those decisions are executed. While intraorganizational power is critical in facilitating the execution of the activities by information technology (IT) departments, it can be expected that some self-interested individuals will act in bad faith in its pursuit. Using resource dependency theory for guidance, a multi-case study of three mid-western universities was carried out to identify dysfunctional behaviours by IT personnel aimed at gaining intraorganizational power or avoiding its erosion. These behaviours are compared to the literature and strategies for mitigating these activities are offered to practitioners.

Published: December 2023

This study examines the relationship between entrepreneurial risk-taking perception and sustainable entrepreneurship intention among SMEs in Algeria, in addition to the precise content of such interventions. It was determined by quantitative research methods using structural equation modeling (SEM) that there is a statistically significant and positive correlation between SMEs’ aim to be sustainable in business and their views of financial, social, and personal risks. The mediation analysis results revealed an even greater association for attitude toward risk. This finding demonstrates the significance of the SME’s risk-taking attitude as a mediating component in the sustainable entrepreneurial aim model of SMEs in Algeria. The results highlight the importance of attitude toward risk in moderating the impacts of entrepreneurial risk-taking views on intentions for sustainable entrepreneurship.

Considerando o compromisso da União Europeia de aumentar substancialmente o envolvimento da população adulta em processos de Aprendizagem ao Longo da Vida, proporcionando, assim, o aumento do nível de qualificação através do desenvolvimento de competências-chave como a competência digital, o estudo em foco neste artigo envolveu duas prisões portuguesas e teve como objetivos identificar potencialidades e limitações da formação com recursos tecnológicos para o desenvolvimento de competências digitais e de cidadania e perceber quais as motivações dos/as reclusos/as em participar em formações apoiadas por tecnologias digitais e com que expectativas o fazem. Do ponto de vista empírico, o estudo recorreu a questionários e entrevistas a adultos/as reclusos/as que frequentaram ações de formação no âmbito de dois projetos em curso em Portugal. O estudo identificou vantagens na frequência de cursos de formação híbridos, com componente à distância, como a superação de barreiras geográficas e temporais, a flexibilidade de horários e a responsabilidade na construção do conhecimento, contribuindo ainda para o desenvolvimento de competências digitais, comunicação, interatividade, partilha, autonomia e ocupação do tempo. No entanto, foram também identificadas limitações relacionadas com a falta de acesso à Internet, as rotinas estabelecidas nas prisões e a desmotivação.
EXAMINING THE SYMBOLIC MEANING OF AL JABBAR GRAND MOSQUE IN BANDUNG
Authors: Jamaludin J. , Santosa Imam , Anita Juarni
Published: December 2023

This paper discusses the formal and symbolic aesthetic meaning of the Al Jabbar Grand Mosque, a new mosque in Bandung, Indonesia, designed by Ridwan Kamil. Like Ridwan Kamil's previous works, the Al Jabbar mosque in Bandung has a contemporary design. The general concept of the architect in designing this mosque has been published in the mass media, and the public already knows the design idea of the mosque. However, there are still features within the mosque that need to be described and analyzed so that the general public can understand the architect's intention. This paper proposes answers through interpretation methods with a descriptive analysis approach to understand the symbolic meaning of the new features of the mosque. The symbolic aesthetic used in the analysis uses symbolic aesthetics from the culture of the Sundanese people, one of the ethnic groups in Indonesia, which is geographically the cultural background where the mosque was built. The analysis found that the meaning the mosque forms, apart from having a bond of meaning with the mosque, also has a bond of meaning with the local culture. The architect made it differently with the spirit of novelty to enrich Islamic architecture and design treasures.

Published: December 2023

This article is aimed at explaining how the political behavior of Towani Tolotang, a minority religious group in Indonesia, unfolds by using fiqh al-‘aqaliyyāt (Islamic jurisprudence of the minority) perspective. Accordingly, the current article discusses three aspects. First, the Towani Tolotang’s political activities. This correlates with the group’s position, which in terms of quantity is far fewer than the Muslim majority. Second, the national constitution’s provision ensures the rights of each citizen to participate in various aspects of life, including political freedom regardless of their position and status. Third, the Muslim majority group’s acceptance of the Towani Tolotang’s political activities. The data analyzed in the research were collected by observing the daily life of the Towani Tolotang, interviewing some informants, and studying document as well as literature studies on relevant documents and literary sources. According to the data analyses, it was found that there are apparent changes in the political behavior of this particular minority group, which not only include the distribution of support given to various political parties but also the active engagement of the group’s elites and followers in the general election wherein some of them have even become a member of the local level legislative body.  The present article asserts that the Towani Tolotang is one of the minority groups in Indonesia that has acquired space to actively participate in politics, although occurring at the local level. This is not only due to the Muslim majority’s acceptance, but the Towani Tolotang group’s fraternization with Muslims as well.
