A redução da renda do brasileiro após a pandemia, o aumento da demanda das defensorias públicas e a necessidade de fortalecimento da instituição
Authors: Ribeiro Cauê Bouzon Machado Freire , Zanetti Rodrigo Alves
Published: July 2022

Partindo de uma análise de dados que apontam para uma significativa queda na renda média do brasileiro, sobretudo da população mais pobre, este artigo analisa o cenário atual e futuro da instituição pública responsável por, entre outras diversas funções, exercer o mandamento constitucional de prestar assistência jurídica aos mais necessitados. Observando e explanando sobre o pífio número de defensores públicos estaduais e federais no país, o texto percebe, de forma crítica, o não fortalecimento da instituição, um projeto antidemocrático muito bem articulado. Buscando revelar a curiosidade e a dúvida, que levam à discussão e ao diálogo, o artigo, em sua conclusão, deixa implicitamente em aberto duas questões, a primeira deles levantada pela Ministra Carmen Lúcia: a quem interessa enfraquecer a Defensoria Pública? A segunda, que parece já contar com uma infeliz resposta negativa: a promessa constitucional de presença de defensorias em todas as unidades jurisdicionais se concretizará, fazendo com que o natural aumento da demanda pós-pandemia seja suportado?

Authors: KURT ELIF , GÜLER FATMA
Published: July 2022

The parallel curves are especially used in numerically controlled machining where a biaxial machine defines the shape of the cut made with a round cutting tool. In this study, trajectory ruled surfaces are investigated whose base curve is the parallel curve of a prescribed curve. Some results related with their developability and minimality are obtained. In addition, the conditions are investigated for the base curve to be a special curve. Parallel trajectory ruled surfaces are illustrated with examples.
NUMERICAL SOLUTIONS OF DIFFERENTIAL-ALGEBRAIC EQUATIONS (DAEs) USING LEGENDRE POLYNOMIALS APPROXIMATIONS
Authors: AKAR MUTLU
Published: July 2022

In this paper, the Legendre polynomials approximations are studied for the numerical solutions of differential-algebraic equations (DAEs). An algorithm of the method constructed using Legendre polynomials approximations is developed to solve DAE systems. Two test problems are answered to illustrate the Legendre polynomials approximations, and then the obtained solutions are confronted with the exact solutions of the problems. As a first step, the power series of an allowed equation system is determined, in second step it is converted into Legendre polynomials approximations structure which allows an arbitrary order. Furthermore, to get numerical solution of DAEs with Legendre polynomials approximations, a Maple algorithm is implemented. Graphs of obtained solutions are sketched, and are created tables to compare the exact solutions by using Maple programming.

Authors: DRAGOMIR OTILIA ELENA
Published: July 2022

Among the challenges in the field of the paper we have identified the necessity of control methods and tools of mobile robots (MRS) equipped with robot manipulator (RM) serving assembly/ disassembly mechatronic lines (A/DML).The framework of the work reported here is represented by SMART&ASTI A/DML served by two MRs with RM, working collaboratively and the goal is development of a multi-agent system able control interactively trajectories of MRs, working collaboratively to serve the A/DML, by avoiding the collisions between them. The advantage offered by the proposed solution consists in graphical representation of the trajectory of MRs working collaboratively, as well as the current status of them, while the users are able to interact intuitively with the MRs trough the proposed GUI The added value of the paper consists in the implementation of multi-agents systems in a complex A/DML served by two MRs equipped with RM, working collaboratively, the increased autonomy in communication between the entities of entire system, and the adaptive control of MRs trajectories.

Authors: Herrera Lorena Paola , Von Below Jonathan , De Rito Mara
Published: July 2022

A lo largo de su historia, el ser humano ha experimentado una profunda desconexión con la naturaleza de la cual forma parte. Como consecuencia, los problemas ambientales y la falta de cuidado hacia la vida han ido en aumento. La forma en que las personas se perciben en relación a la naturaleza puede influir en su comportamiento ambiental. El objetivo de este trabajo fue explorar la percepción que las personas de una ciudad costera de Argentina tienen de conexión naturaleza y su vinculación con el comportamiento proambiental. En esta investigación predominó la perspectiva metodológica cualitativa y se utilizó la encuesta autogestionada como método de recolección de datos. Los resultados de 220 encuestas identificaron que las personas, en general, se percibieron a sí mismas en conexión con la naturaleza. Se encontraron respuestas positivas en relación con el comportamiento proambiental hacia algunas actitudes (por ej., reciclaje, uso eficiente del agua), y menos positivas hacia otras (por ej., realización de compostaje, participación en ONGa). Este trabajo permitió identificar puntos clave para comprender parte del accionar cotidiano de las personas en el cuidado del ambiente, y aportar a las normativas locales para fomentar el cuidado de espacios verdes y la gestión de residuos domiciliarios.

Abstract

Throughout history, human beings have experienced a profound disconnection with nature of which they are a part. As a consequence, environmental problems and lack of care for life have been increasing. The way people perceive themselves in relation to nature can influence their environmental behavior. The aim of this work was to explore the perception that people in a coastal city in Argentina have of nature and its link with proenvironmental behavior. This research was dominated by a qualitative methodological perspective and used self-managed surveys for data collection. The results of 220 surveys identified that people, in general, perceived themselves in connection with nature. Positive responses were found in relation to proenvironmental behavior towards some attitudes (e.g., recycling, efficient water use), and less positive towards others (e.g., composting, NGO participation). This work allowed us to identify key points to understand part of the daily actions of people in caring for the environment, and to contribute to local regulations to promote the care of green spaces and the management of household waste.

In the agronomic management of maize (Zea mays L.), chemical fertilizers can be substituted for fertilizing techniques that reduce the pollutant effect of the excessive use of commercial fertilizers. The hypothesis was the green manure of legumes with or without the inoculation of microorganisms are capable of promoting agronomic characteristics of X’mejen Naal maize, comparable to conventional fertilization. In order to measure the effect in the agronomic characteristics of X´mejen Naal maize, an experiment was designed in complete randomized blocks in a bifactorial arrangement with four repetitions, in which three green manures were tested, with or without the inoculation of Fosfonat (endomycorrhizas, EM, plus nitrogen fixating bacteria, NFB). Treatments were Mucuna (Mucuna pruriens, T1=MUC), Xpelón (Vigna unguiculata, T2=PEL), Ibes (Phaseolus lunatus, T3=IBE), inoculated Mucuna (T4=MUCEM), inoculated Xpelón (T5=PELEM), inoculated Ibes (T6= IBEEM) and the control with the incorporated biomass of weeds plus the addition of 200 kg ha-1 of diammonium phosphate (T7=ARDAP). Results showed that there were only differences caused by the types of green manure and their interaction with the inoculated symbionts in the fresh weight or biomass in X´mejen Naal maize. IBE and ARDAP stood out in fresh weight (1162 and 1251 g), dry weight (168.6 and 163.6 g), 7.3 Mg ha-1 (Megagrams per hectare) in the dry aerial biomass in the maize plants, respectively. Despite the grain yield of maize was similar among treatments, it was noticeable that the higher average yields were also observed in IBE and ARDAP with 3.5 and 3.3 Mg ha-1 respectively. All yields (fodder and grain) managed to express the potential of the X´mejen Naal, which is relevant to recommend the use of green manures as an agro-environmental alternative to conventional fertilization in the Luvisol soils of Campeche.

Background. Achatina fulica (A. fulica) snail slime was well known having many advantages especially as moisturizer and antimicrobial, but enzymatic antioxidant properties have not been studied yet. Objective. This study aimed to find the enzymatic antioxidant properties of snail slime extract and to find photoprotective potency in sunburn. Method. This research was an experimental test using randomized post-test only control group design using 75 male BALB/c mice were divided into 15 groups. There were an untreated group, 4 groups were given various doses of snail slime extract topically, 5 groups were irradiated with UVA 30J/cm2 and 5 groups were irradiated with UVB 200mJ/cm2. Skin biopsy were performed 24 hours after irradiated to be analyzed for enzymatic antioxidants properties of SOD, CAT and GPX, and also histologic changes. Data analysis were conducted with one-way ANOVA and followed by post hoc LSD with SPSS 26. Results. A. fulica snail slime contained enzymatic antioxidant properties of SOD, CAT and GPX respectively 40,59 + 5,79U/mL; 13,73 + 6,13 U/mL and 17,64 + 3,84 mmol/L. These antioxidant properties showed role of photoprotector compared to groups that had been radiated with UVA nor UVB. Topical use of snail slime extract significantly increased the level of SOD, CAT and GPX in sunburn model mice (p<0,05). This study also showed snail slime extract could prevent skin damage caused by UVA nor UVB histologically. Conclusion. Enzymatic antioxidants of A. fulica might have a photoprotector potency.
Application of ARIMA-GARCH Model to Estimating Expected Shortfall in BMRI Stocks
Authors: Simanjuntak Alberto
Published: July 2022

Stocks are one of the best-known forms of investment and are still used today. In stock investment, it is necessary to know the movement and risk of loss that may be obtained from the stock investment so that investors can consider the possibility of profit. One way of calculating risk is to use the Expected Shortfall (ES). Because the stock movement is in the form of a time series, a model can be formed to predict the movement of the stock which can then be used for ES calculations using time series analysis. The purpose of the study was to determine the expected shortfall value of BMRI shares using time series analysis. The data used for this research is the daily closing price of shares for three years. In the time series analysis stage, the models used in predicting stock movements are Autoregressive Integrated Moving Average (ARIMA) for the mean model and Generalized Autoregressive Conditional Heteroscedasticity (GARCH) for the volatility model. The average value and variance obtained from the model are then used in calculating the ES on BMRI stock. Based on the results of the study, it was obtained that BMRI's stock had an ES of 0.008116. This means if an investment is made for BMRI shares of IDR 1,000,000.00 for 37 days (5% of 751 days) for an investment period with a 95% confidence level, the expected loss to be borne by the investor is IDR 8,116.00.

POTRET DAKWAH DALAM MENGAKOMODASI NILAI-NILAI KEARIFAN LOKAL MENUJU ASIMILASI BUDAYA
Authors: Wahib Abdul
Published: July 2022

Pada tulisan ini memuat tentang potret dakwah dalam mengakomodasi nilai-nilai kearifan lokal menuju asimilasi budaya. Sejak awal kehadiran agama ke muka bumi telah terjadi interaksi dan dialog  dengan budaya yang telah ada di tengah masyarakat khususnya masyarakat Arab Jahiliyah, hal inilah kemudian Nabi saw. diperintahkan oleh berdakwah harus dengan bijaksana (hikmah), menggunakan pesan nasihat yang baik (mu’idzhatul hasanah), dan berupaya berdialog dengan cara yang terbaik (wajadilhum billati hiya ahsan),dialog ini penting dilakukan agar menghindari jarak yang terlalu jauh antara da’i dan masyarakat sebagai objek dakwah. Dalam perjalanannya ajaran agama yang suci ini sering kali dinodai oleh hal-hal yang justru kontra produktif dengan esensi ajaran agama itu sendiri, misalnya memahami teks-teks agama secara sempit dan subjektif. Akibat yang ditimbulkan dari pemahaman ini ada segelintir oknum dari umat Islam yang gemar saling membid’ahkan amal sesama muslim bahkan hingga menuduh kafir sesama muslim, model pemahaman dan pengamalan ajaran agama seperti secara prinsip bertentangan dengan misi Islam yang rahmah terhadap semua elemen mahluk Allah swt. yang hidup di alam semesta di setiap tempat dan keadaan.

Objective Micro-ultrasound is an imaging modality used to visualize and target prostate cancer during transrectal or transperineal biopsy. We evaluated the effectiveness of a micro-ultrasound training program and estimated the learning curve for prostate biopsy. Methods A training program registry was assessed for the rate of clinically significant prostate cancer (csPCa, grade group ≥ 2), negative predictive value, and specificity at each stage of the program. Nine metrics of biopsy quality were evaluated in 4 stages for each practitioner. Non-linear fitting and logistic regression models were used to evaluate the time-course of these metrics over training. Results Thirteen practitioners from 8 institutions completed stages 1 to 3 of the program, and 9 completed all 4 stages. Over 1190 micro-ultrasound biopsy procedures were performed. Detection of csPCa increased from 40% to 57% from stage 1 to stage 4 (P < 0.01). Stage 4 “expert” level was independently associated with higher detection of csPCa when correcting for overall risk factors (OR 1.95; P = 0.03). Limitations include the retrospective analysis and variation in biopsy protocols. Conclusion The micro-ultrasound training program was effective in improving biopsy quality and rate of csPCa detection. The presented learning curve provides an initial guide for acquiring expertise with real-time micro ultrasound image-guided biopsy.

Rodolfo Walsh: o jornalista-militante que “derrotou” Kennedy e a CIA na Baía dos Porcos
Authors: Figueira João
Published: July 2022

O jornalista argentino Rodolfo Walsh contribuiu decisivamente para a derrota das forças que, com apoio militar dos Estados Unidos, tentaram, em abril de 1961, invadir Cuba e depor Fidel Castro. Fruto dos conhecimentos em criptografia, decifrou uma mensagem do governo da Guatemala para Washington, interceptada nos escritórios da Prensa Latina, onde trabalhou por dois anos. A mensagem dava todos os detalhes sobre a hora, data e local do desembarque e ataque à ilha. No contexto da Guerra Fria, o trabalho do jornalista e da Agência, totalmente comprometidos com o processo revolucionário, filiam-se no conceito do jornalismo-militante, ou seja, na ideia da informação ao serviço dos objetivos políticos. Porém, a questão da Baía dos Porcos também teve a sua repercussão no The New York Times, que foi sensível à perspetiva da CIA sobre o modo como o jornal deveria tratar o assunto. O que releva a importância e a atualidade de se discutirem as relações entre jornalismo e política.

Authors: Abdelrahman Ahmed S. , Madkour Sherihan S. , Ekladious Mena E.Y.
Published: July 2022

Introduction

The liver imaging reporting and data system (LI-RADS) is a structured reporting system that categorizes hepatic observations according to major imaging features and lesion size, with an optional ancillary features contribution. This study aimed to evaluate inter-reader agreement of dynamic magnetic resonance imaging (MRI) using LI-RADS v2018 lexicon.

Material and methods

Forty-nine patients with 69 hepatic observations were included in our study. The major and ancillary features of each hepatic observation were evaluated by 2 radiologists using LI-RADS v2018, and the inter-reader agreement was allocated.

Results

The inter-reader agreement of major LI-RADS features was substantial; κ of non-rim arterial hyperenhancement, non-peripheral washout appearance, and enhancing capsule was 0.796, 0.799, and 0.772 (p < 0.001), respectively. The agreement of the final LI-RADS category was substantial with κ = 0.651 (p < 0.001), and weighted κ = 0.786 (p < 0.001). The inter-reader agreement of the ancillary features was substantial to almost perfect (κ range from 0.718 to 1; p < 0.001). An almost perfect correlation was noted for the hepatic lesion size measurement with ICC = 0.977 (p < 0.001).

Conclusions

The major and ancillary features of the LI-RADS v2018, as well as the final category and lesions size, have substantial to almost perfect inter-reader agreement.

Laporan keuangan adalah kunci untuk memantau kinerja bisnis. Pelaku Usaha Mikro Kecil Menengah (UMKM) masih banyak yang belum menyadari pentingnya membuat laporan keuangan. Salah satu alasan pelaku UMKM tidak membuat laporan keuangan karena dipandang sulit, menyita waktu, merepotkan dan tidak penting. Pencatatan akuntansi berbasis teknologi masih sangat jarang ditemukan terutama pada UMKM. Di era saat ini, teknologi dapat membantu para pelaku UMKM dalam pencatatan akuntansi usahanya. Pelaku usaha UMKM Pondok Petir Sejahtera berasal dari berbagai macam kalangan dari kelompok usaha yang berbeda- beda. Para anggota UMKM masih menggunakan pembukuan manual untuk mencatat keuangan usahanya bahkan ada yang tidak melaksanakan pencatatan transaksi usaha yang dijalankan. Beberapa pelaku UMKM berpendapat bahwa tanpa pembukuan, usaha akan berjalan lancar dan selalu menghasilkan keuntungan. Hal tersebut menyebabkan arus keuangan tidak diketahui dan akan menimbulkan kerugian serta sulit bagi UMKM dalam mendapatkan akses permodalan dari lembaga keuangan formal. Berdasarkan permasalahan tersebut, diperlukan sosialisasi dan pelatihan penggunaan aplikasi berbasis Android “Buku Warung” bagi pelaku usaha di UMKM Pondok Petir Sejahtera. Tujuan dari pengabdian ini yaitu agar anggota UMKM Pondok Petir Sejahtera paham pentingnya laporan keuangan serta mudah dalam pencatatan transaksi bisnis menggunakan aplikasi akuntansi berbasis android.

Introduction and Aim: Head and neck is affected in 11-33% of extra-nodal Non-Hodgkin Lymphomas with the Waldeyer’s ring comprising 50% and among which palatine tonsils are most commonly involved.
 
Materials and Methods: A retrospective analysis was performed using medical case files to study the demographic and clinical details of 13 patients diagnosed with primary lymphoma of palatine tonsil between 2011 and 2020 at a tertiary care hospital in coastal India.
 
Results: Mean age was 49.7 years with a male preponderance. The usual presentation was either as a unilateral palatine mass or neck swelling with dysphagia, odynophagia and otalgia. All patients had high-grade lymphoma, diffuse large B-cell lymphoma was the commonest type. B-symptoms were seen more often in B-cell lymphoma; stage I was the most frequent. Stage at diagnosis was statistically significant when compared with B-symptoms, bulky disease and International Prognostic Index (IPI) (p-values of 0.02, 0.02 and 0.035 respectively). Overall survival (OS) rate was 44.44%, being higher in females than in males. Higher OS rate was noted for IPI of 1 & 2, and early stage lymphoma, unilateral tonsillar enlargement, normal lactate dehydrogenase, and European Cooperative Oncology Group score of 0. Combined chemoradiation proved to be better (50% OS) than chemotherapy (33.33% OS) alone.
 
Conclusion: Lymphoma must be suspected in unilateral or bilateral asymmetrical tonsillar enlargement, especially in the older age group. Histopathology with immunohistochemistry plays a crucial role in diagnosis and typing of lymphoma, for proper and early institution of treatment with chemoradiation.
Nutraceutical properties of Vinca rosea
Authors: - Prabhavathi , Mal Anuradha
Published: July 2022

Vinca rosea (C. roseus), a member of the Apocynaceae family, is a popular medicinal plant found in many countries. It's gaining popularity because it's been discovered to have a variety of phytochemicals having a wide range of biological actions, such as free radicle scavenging, hypoglycemic, antibacterial, antifungal, and cancer-fighting properties. The most important alkaloids isolated from vinca plant is vincristine and vinblastine. These were the first anticancer medicines obtained from plants to be tested in clinical trials. New indole alkaloids have recently been identified from this plant, including human cancer cell lines which were efficiently suppressed in vitro by 14', 15'-didehydrocyclovinblastine, 17-deacetoxyvinamidine, and 17-deacetoxycyclovinblastine. This plant is high in alkaloids and other secondary metabolites. Vindoline, vindolidine, vindolicine, and vindolinine are some of the important alkaloids found in the leaf extracts of V. rosea which showed anti-diabetic activity in vitro. These findings imply that C. rosea remains a potential bioactive chemical source that warrants more investigation. This study gives a summary of the plant's botanical features, its traditional and current medical uses and phytochemical profiles. In addition, the extracts and bioactive components generated from this plant's supposed health advantages were investigated in order to establish its potential as medicinal agents.
Reducing conflicts within rural women's self help groups in Hwange District, Zimbabwe
Authors:   , Nyathi Cresencia
Published: July 2022

The thesis examines the operations and outcomes of the Self Help Groups (SHGs) in Matetsi ward. It examines the causes of conflicts and consequences of the conflicts in the SHGs. This is achieved by adopting the conflict transformation approach. Succinctly, the theory views conflict as not necessarily destructive, but as a vehicle for change. This therefore, has implications for one’s understanding of the causes of conflicts. SHGs have been adopted by rural women so that they can work collectively to address their socio-economic problems. The study was conducted in Matetsi ward, Hwange District where conflicts within the groups were broadly detected. The information used in the study were produced from face-to-face interviews, focus group discussions, minute books and testimonials throughout field work in the designated ward. The study exposed that conflicts in the study location emanated from delays in loan repayments by SHG members. Individuals’ failure to fulfil their obligations of saving and returning loans on time created tensions which in turn resulted in conflict among the group members. The conflicts became complex and recurred due to unaddressed animosity, fear and anger, resulting in frustrations in the groups. Conflicts in the groups also led to the collapse of some of the groups. The research findings indicated that SHGs were not only sources of income for rural women, but also represented a yearning for self-sufficiency among rural women in spite of the socio-economic strife in Hwange District.
An investigation into entrepreneurial intent amongst final year commerce students at the Durban University of Technology
Authors:   , Ndovela Symentheus Mfundo
Published: July 2022

This study investigated the concept of entrepreneurial intent within a South African Higher Education (HE) context using a sample of final year commerce students at the Durban University of Technology (DUT). The backdrop of this is within growing calls for universities to be located more within the ideal and agenda of generating future entrepreneurs for the economy. Further, arguments are made that graduates within South African Higher Education (HE) may possess the necessary theoretical knowledge but fall short concerning coming up with innovations that are responsive to the changing and diverse labour market. Entrepreneurship, thus, emerges as a possible panacea to the challenges affecting HE in South Africa. The aim of the research was to investigate factors that influence a student’s entrepreneurial intent within a South African HE context. A quantitative survey design was implemented amongst a sample of 250 respondents studying at the DUT. Correlation and regression analysis were used to test relationships between variables. The findings show a positive relationship to exist between individual risk taking propensity and variables such as a) subjective norms; b) perceived behavioural control; c) proactive personality; d) entrepreneurial education and e) student attitude towards entrepreneurial education and intentions. The findings provide a useful precursor to encouraging entrepreneurial efforts within HE in South Africa. Practitioners can use the findings of this work to come up with interventions that promote the development of an entrepreneurial culture within the South African context, especially using a vulnerable yet important cohort within the youth of the country.
The influence of service quality on the post-dining behavioural intentions of customers at Cargo Hold, Ushaka Marine World

The purpose of this research study was to investigate the influence of service quality on the post-dining behavioural intentions of customers in a fine dining setting. The National Restaurant Association (2014 as cited in Ruggless 2014: 20 stated that the fine dining restaurant segment is constantly losing out on the restaurant industry market share. In order to remain competitive, restaurants need to tender service that meets the expectations of customers, as perceived service quality affects post-dining behavioural intentions (Prayag, Khoo-Lattimore and Sitruk 2015: 27). In an attempt to devise strategies to rescue the sinking fine dining restaurant segment, this research study developed a conceptual framework model and tested its paths through path analysis, using structural equation modelling. The research study modified a DINESERV scale to obtain primary data from respondents. The modified DINESERV attained a high reliability and validity score. It was further subjected to confirmatory factor analyses and all the KMO and Bartlett’s requirements for factor analysis were satisfied. Data was collected by means of self-administered questionnaires at Cargo Hold restaurant after agreement was reached with the management team. The convenience sampling method of data collection was applied. Diners were only given the questionnaire upon receipt of their consent to participate in this study. A total of 400 survey questionnaires were distributed. However, only 361 were deemed suitable for analysis. These 361 usable survey questionnaires represent a 90.25% response rate for this research study. Hypotheses were tested on a hybrid of structural equation modelling path analysis and Spearman’s correlation coefficients. The results showed a positive correlation between service quality and behavioural intentions, with customer satisfaction indirectly exerting a significant effect between these constructs. The research study concludes with implications and direction for future research.
