Nivel freático, recarga y caudal básico en la cuenca del arroyo Del Azul
Authors: Zeme Sofía , Varni Marcelo
Published: July 2022

Se analizan registros freatimétricos continuos de 2007 a 2014 en seis perforaciones ubicadas en la cuenca del arroyo del Azul. Las perforaciones son de poca profundidad (menores a 6 m) porque su objetivo es monitorear el nivel freático, y se distribuyen tanto en la zona de cabeceras como en el sector llano. Se identifican períodos más secos, con niveles más profundos, y períodos húmedos, con niveles que llegan a alcanzar 0,5 m de profundidad. La recarga se calcula mediante el método de fluctuación del nivel freático, para lo cual es necesario estimar el almacenamiento específico en la ubicación de cada pozo. Ello se hace mediante un procedimiento gráfico donde se vuelcan los eventos precipitación-ascenso de nivel. Se calculan las recargas totales mensuales medias y las variaciones de almacenamiento para cada pozo en el período analizado. Finalmente, se analiza la relación entre el nivel freático en cada perforación y el caudal base en una sección del arroyo del Azul.

 

Abstract

Groundwater continuous records from 2007 to 2014 in six wells located on the Azul Creek watershed are analyzed. The wells are shallow (less than 6 m) because its objective is to monitor the water table, and are distributed both in the headers and in the plain sector. Drier periods, with deeper levels, and wet periods, with levels that can reach only 0.5 m depth are identified. Recharge is calculated by the water table fluctuation method, for which is necessary to estimate the specific yield for the location of each well. This is done through a graphical procedure where precipitation-level rise events are included. Total mean monthly recharge and storage variations for each well in the period under analysis are calculated. Finally, the relationship between the groundwater level in each well and base flow in a section of the Azul Creek is analyzed.

Valoración del potencial recreativo de los ríos en base a las características geográficas observables
Authors: Salinas Chávez Eros , Teixeira dos Santos Eva , Ribeiro Ayach Lucy
Published: July 2022

Desde tiempos inmemoriales los ríos han jugado un rol importante en el desarrollo de la humanidad y han sido utilizados para diferentes fines socio económicos, entre ellos para el esparcimiento. En la actualidad, los ríos constituyen un atractivo natural de interés para la práctica de diferentes actividades recreativas y deportivas al aire libre. Sin embargo, no todos los ríos, ni los diferentes tramos o sectores de un mismo río, presentan iguales características, ni tienen las mismas posibilidades y/o limitaciones para el uso recreativo y el ocio de la población residente y visitantes. El objetivo de este trabajo es describir y proponer un procedimiento de valoración del potencial recreativo de los ríos y sectores de los mismos, -para el baño y la natación- en base a características observables, en su mayoría a simple vista, geográfico-paisajísticas (naturales y antrópicas), estéticas, patrimoniales. y otras relacionadas con las instalaciones de servicios existentes. En total 31 variables independientes son valoradas a través de la observación in situ. Los resultados de estas valoraciones pueden facilitar la planificación de las actividades e inversiones necesarias para el uso recreativo y conservación de nuevos sitios o lugares de interés; además, en aquellos ríos actualmente explotados, contribuye a establecer las medidas adecuadas para reducir los impactos negativos derivados de su uso y favorecer su recuperación.

 

Abstract

From time immemorial, rivers have played an important role in the development of humanity and have been use for different socio-economic purposes, including for recreation. At present, rivers constitute a natural attraction for the practice of different recreational and sports and outdoors activities. However, not all rivers, nor the different sections or sectors of the same river, present  the  same  characteristics, nor  do  they  have  the  same  possibilities  and / or limitations  for the recreation and leisure of the resident population and visitors. The purpose of this paper is to describe and propose a procedure for assessing the recreational potential of rivers or sections of the same, -for bathing and swimming- based on observable characteristics, mostly from naked eye. We refer mainly to geographic characteristics, those of the landscape (natural and anthropic), as well as aesthetic, patrimonial and other characteristics related to existing service facilities. In total 31 independent variables are assessed through on-site observation. The results of these assessments can facilitate planning the activities and investment necessary both for the recreational use and for the conservation of new sites or places of interest. Furthermore, with regards those rivers currently exploited, it contributes to establishing adequate measures to reduce the negative impact derived from its use and facilitate its recovery.

Authors: Hartanto Selamet , Sup Devid Frastiawan Amir
Published: July 2022

AbstractThe application of a hybrid contract is a necessity that cannot be avoided and its application is supported by the principle of muamalah which applies the principle of permissibility as long as there are no prohibitions from the nash. This research aims to describe the concept of a hybrid contract and its implementation in Islamic financial products in Indonesia. The methodology used is descriptive qualitative literature. The results obtained, a hybrid contract is an agreement between two parties to carry out a muamalah which includes two or more contracts. The permissibility of a hybrid contract is based on the legal principle that the origin of muamalah is permissible. In general, the limits agreed upon by the scholars regarding several criteria for hybrid contracts to be allowed by sharia, namely not what is prohibited from the nash, not being a means to something that is forbidden, not being used as a hilah (strategy) to take usury in other ways, and is not included in the contract to the contrary. Fatwa DSN-MUI according to hybrid contracts on Islamic financial products in Indonesia, namely mudharabah musytarakah, musyarakah mutanaqisah, musyarakah muntahiyah bi al-tamlik, and al-ijarah al-muntahiyah bi al-tamlik. AbstrakPenerapan hybrid contract merupakan sebuah kebutuhan yang tidak dapat dihindari dan penerapannya didukung oleh prinsip muamalah yang memberlakukan asas kebolehan sejauh tidak ada larangan nash. Penelitian ini bertujuan untuk mendeskripsikan hybrid contract dalam konsep dan Fatwa DSN-MUI pada produk keuangan syariah di Indonesia. Metodologi yang digunakan adalah kualitatif deskriptif kepustakaan. Hasil yang didapat, hybrid contract merupakan kesepakatan dua pihak untuk melaksanakan suatu muamalah yang meliputi dua akad atau lebih. Kebolehan hybrid contract didasarkan atas prinsip hukum asal dari muamalah adalah boleh. Secara umum batasan yang disepakati oleh para ulama mengenai beberapa kriteria bagi hybrid contract agar diperbolehkan secara syar’i, yaitu bukan yang dilarang dalam nash, tidak menjadi sarana ke suatu yang diharamkan, tidak dijadikan sebagai hilah (siasat) untuk mengambil riba dengan jalan lain, dan tidak termasuk ke dalam akad-akad yang berlawanan. Fatwa DSN-MUI mengenai hybrid contract pada produk keuangan syariah di Indonesia, yaitu mudharabah musytarakah, musyarakah mutanaqisah, musyarakah muntahiyah bi al-tamlik, dan al-ijarah al-muntahiyah bi al-tamlik.

Published: July 2022

AbstractRisk is something that cannot be predicted when it occurs and can cause a loss. Efforts to protect yourself become a necessary action to minimize the losses incurred. The millennial generation's concern for insurance is still lacking and tends to be more concerned with lifestyle than efforts to protect themselves by having insurance. This study aims to analyze the effect of insurance literacy, religiosity, and service quality on the millennial generation's interest in using sharia insurance. This study uses a quantitative approach, by collecting primary data taken through a questionnaire instrument with a total sample of 148 respondents. The data analysis technique used regression analysis with SPSS analysis test tool. The findings of this study indicate that the variables of insurance literacy, religiosity and service quality have a significant effect on the millennial generation's interest in using sharia insurance. Furthermore, partially found in this research that the religiosity variable has no effect on the millennial generation's interest in using sharia insurance. This research is expected to contribute to providing an overview of the relationship between insurance literacy, religiosity and views on service quality in the sharia insurance industry in increasing the sharia insurance market, especially among millennials. AbstrakRisiko merupakan hal yang tidak dapat diprediksi kapan terjadi dan dapat menimbulkan sebuah kerugian. Upaya memproteksi diri menjadi sebuah tindakan yang diperlukan guna meminimalisir kerugian yang ditimbulkan.

Published: July 2022

COVID-19 is a disease that was first discovered in Wuhan, China and caused the 2019-2020 coronavirus pandemic. This virus can cause respiratory tract infections such as flu when infecting humans. According to Ministry of Health of the Republic of Indonesia, the number of confirmed cases of COVID-19 in Indonesia at March 2021 is 1,511,712 with 40,858 deaths and 1,348,330 recovered. For that, Indonesia is declared to have the highest confirmed cases in ASEAN. Several studies have been carried out to handle some cases by using the data mining techniques such as Decision Tree or Linear Regression algorithm, as example to classify the respiratory diseases and predict pregnancy hypertension. In this study, we tried to analyze COVID-19 cases in Indonesia and conducted an experiment of predicting COVID-19 new cases with the Decision Tree (CART) and Linear Regression algorithms. Then we will compare the values of these two algorithms by using R2 Score to evaluate the prediction performance. The results of this analysis state that DKI Jakarta province has the highest number of positive cases, cures and deaths in Indonesia. The value of the comparison results from the R2 Score obtained in the Decision Tree algorithm reached 95.69% (training) and 92.15% (testing) while the Linear Regression algorithm reached 79.93% (training) and 77.25% (testing).

Published: July 2022

Data security issues are an important aspect of data and information communication over networks. In addition, it is also necessary to look at the security side of the software. In addition to software, computers have an internet protocol in the form of HTTP which is commonly used to access websites. On the LMS website, students have access to lecture materials, discussion forums with lecturers and access to assignments given by lecturers. Wireshark is used to analyze network protocols, can log all packets going through and display detailed data. The purpose of this study is to use a Wireshark application to sniff LMS and pinpoint vulnerabilities in the system. The results of the sniffing process carried out using Wireshark on an LMS that uses the HTTP protocol clearly indicate the absence of encryption and expose the risk of vulnerabilities to the system. Recommendations given to LMS are the use of HTTPS protocol, implementation of Multi Factor Authentication, website log monitoring and password management. Recommended password management are periodic password changes, standardization policies for the use of characters in passwords and password hashing. It is hoped that when the recommendations are implemented it will improve security on the LMS website and reduce risks in data communications

Published: July 2022

Esta pesquisa propõe investigar e compreender as formas de participação do público no fotojornalismo em portais de notícia, no contexto da cultura da convergência, em especial da cultura participativa. Adotou-se o método da observação direta e da análise de conteúdo (BARDIN, 1977) para analisar os portais DOL, UOL e Clarín, respectivamente de esferas local, nacional e internacional. Partindo de um estudo exploratório-descritivo para selecionar os portais e analisá-los, seguiu-se para a natureza explicativa da pesquisa, identificando dois tipos de uso da produção fotográfica do público na construção da notícia: indução e apropriação. Realizando-se a análise em três momentos (2017, 2019 e 2020), os resultados indicam que os portais vêm incorporando a participação do público, porém, com certas restrições, a exemplo da ausência de autoria.

A pandemia da covid-19 nas capas de Veja e Época: uma cobertura contaminada por Bolsonaro
Authors: Amarante Erivelto
Published: July 2022

O artigo analisa as capas das revistas semanais Veja e Época durante a cobertura da pandemia de Covid-19. O objetivo é verificar como os dois semanários enquadraram em suas manchetes a crise sanitária vivida pelo país e o tratamento dispensado ao presidente Jair Bolsonaro, cuja atuação foi alvo de críticas no período. O corpus é constituído de 53 edições, perfazendo todos os números publicados em 2020 entre março, mês dos primeiros casos, e agosto, quando o país chegou à marca de 100 mil mortes. Trabalhamos com duas hipóteses. A primeira considera que as duas revistas exploraram mais as editorias de política e economia do que a de saúde. A segunda faz menção à polêmica atuação de Bolsonaro na gestão da crise e acredita que o presidente tenha recebido uma cobertura mais negativa da Época, editada pelo grupo de mídia que o presidente considerou como sua “inimiga". O resultado mostrou que as capas sobre a pandemia oscilaram no período, mas tiveram mais evidência que as de economia. Além disso, as notícias foram mais desfavoráveis ao presidente na Veja.
Além da “bolha”: o papel das plataformas digitais na formação da opinião pública
Authors: Winques Kérley
Published: July 2022

O principal objetivo deste artigo é discutir as transformações na formação de opiniões a partir das mediações algorítmicas presentes nas plataformas digitais. Com a intenção de não abandonar as questões sociais e analisar sentidos e tecnologias de forma separada, os resultados apresentados foram construídos a partir de um estudo de recepção de matriz sociocultural com oito professores sindicalizados e oito evangélicos neopentecostais residentes em Curitiba (PR). Considera-se que há uma lógica mercadológica que orienta a manutenção de poder das plataformas ao mesmo tempo em que os filtros ditam o que será consumido e ignorado, porém, as dimensões estruturantes — igreja, família, trabalho etc. — seguem relevantes no processo de formação das opiniões.

Authors: Minami Yoshiyuki , Ogawa Ruri , Ogura Ichiro
Published: July 2022

Introduction

This study was designed to investigate mandibular lesions using volumetric analysis with bone single-photon emission computed tomography/computed tomography (SPECT/CT).

Material and methods

Eight patients with mandibular lesions underwent SPECT/CT scan acquisition 4 hours after injection of Tc-99m hydroxymethylene diphosphonate (HMDP). Regarding volumetric analysis, maximum standar­dized uptake value (SUV) was obtained using software and a workstation (Q.Volumetrix MI and GEniE-Xeleris 4 DR, respectively). The localization and size of the volume of interest (VOI) can be drawn over the lesion, mesial, distal, and opposite side as normal using the CT, SPECT, and SPECT/CT transaxials, coronals, and sagittals as the anatomical reference. Q.Volumetrix MI can analyse SUV of lesions by organ segmentation using optional pan and zoom imaging. Then, the dosimetry software provided multiple quantitative data for a given VOI. Statistical analyses for the maximum SUV were performed by Mann-Whitney U test. A p-value lower than 0.05 was considered as statistically significant.

Results

Maximum SUVs for medication-related osteonecrosis of the jaw (n = 4, 25.4 ± 4.9), chronic osteomyelitis (n = 3, 14.6 ± 3.1), and squamous cell carcinoma (n = 1, 31.7) were significantly higher than those of the opposite side as normal mandible (3.8 ± 0.7, 4.6 ± 1.8, and 7.4, respectively; p = 0.000).

Conclusions

Volumetric analysis with SPECT/CT could be useful for the evaluation of mandibular lesions, such as detecting and surgical planning.

Introduction

The goal of the study was an assessment of the diagnostic performance of diffusion-weighted images (DWI) and apparent diffusion coefficient (ADC) of magnetic resonance imaging (MRI) in distinguishing local recurrence (LR) of renal cell carcinoma (RCC) from benign conditions after partial nephrectomy.

Material and methods

Thirty-nine patients after partial nephrectomy for solid RCC were enrolled in the study. Patients were followed up using MRI, which included DWI sequence (b = 800 s/mm2). All patients with MRI features of LR were included in the main group (n = 14) and patients without such features – into the group of comparison (n = 25). Apparent diffusion coefficient (ADC) values of suspicious lesions were recorded. In all patients with signs of locally recurrent RCC, surgical treatment was performed followed by pathologic analysis.

Results

The mean ADC values of recurrent RCC demonstrated significantly higher numbers compared to benign fibrous tissues and were 1.64 ± 0.15 × 10-3 mm2/s vs. 1.02 ± 0.26 × 10-3 mm2/s (p < 0.001). The mean ADC values of RCCs’ LR and benign post-op changes in renal scar substantially differed from mean ADC values of healthy kidneys’ parenchyma; the latter was 2.58 ± 0.05 × 10-3 mm2/s (p < 0.001). In ROC analysis, the use of ADC with a threshold value of 1.28 × 10-3 mm2/s allowed us to differentiate local recurrence of RCC from benign postoperative changes with 100% sensitivity, 80% specificity, and accuracy: AUC = 0.980 (p < 0.001).

Conclusions

The apparent diffusion coefficient of DWI of MRI can be used as a potential imaging marker for the diagnosis of local recurrence of RCC.

Introduction and Aim: The bone marrow is responsible for the supply of oxygen and restores the cells that form the blood of a tissue. The objective is to study the cadaveric bone marrow cells from dead children of different regions of Kyrgyzstan.
 
Materials and Methods: Bone marrow examination was performed on 38 cadavers (Bishkek–11, Kara-Balta–9, Cholpon-Ata–10, and Naryn–8) of children dead due to causes unrelated to immunodeficiency.  The cadaveric bone marrow cells from dead children were collected within a day after death.
 
Results: Studies of cadaveric bone marrow cells from dead children in Kara-Balta showed an increase in basophils, eosinophils, lymphocytes, leukoerythroblastosis, and a decrease in myelocytes. Erythroid growth according to the normoblast hematopoiesis was slightly decreased. Megakaryocytes were single or absent (no function) and contained small number of platelets.
 
Conclusion: Cadaveric bone marrow cells taken from dead children who lived near the uranium tailings dump of Kara-Balta, demonstrated an anomaly with the hematopoietic function of the bone marrow, the state of the stroma, the ratio of hematopoietic and adipose tissue, cellular composition, different pathological processes as indicated by myelocytes in comparison to dead children from other regions (Bishkek, Cholpon-Ata, and Naryn).

Momentum of the creation of partnerships between higher education institutions (HEIs) and communities is strong. As their significance intensifies, the question of how to judge their value is garnering increasing attention. In this perspective article, we develop a framework for comprehensively appraising HEI-community partnerships. Constituent parts of the framework are unpacked, and application of the framework is then discussed. The appraisal framework provides a mechanism to document evidence of worth, and most importantly contributes to the continuous improvement and learning imperative of HEI-community partnerships.

This anatomical program for high-school biology teachers, a university-driven capacity- building exercise, achieved its aims of: (1) determining the participants’ profiles; (2) increasing the anatomical knowledge of participants; and (3) evaluating the online program. The webinar program comprised 4 lectures, including discussion, preceded and followed by a test consisting of 19 anatomy questions. Of 867 high-school biology teachers who registered an interest, 222 completed the post-program test and feedback questionnaire; however, only 153 (111 females, 42 males) completed both pre-program and post-program tests and the feedback questionnaire. A significant (P<0.001) increase in the overall post-program scores (88.9%: male 89.5±16.52%; female 88.7±17.38%) compared to the pre-program test scores (56.3%: male 56.1±15.66%; female 56.5±16.82%) was observed, the increase being irrespective of age, level of education or teaching experience. The program attracted participants from throughout Indonesia rather than just those close to the university. There was an overall improvement in test scores, supporting the effectiveness and efficiency of the online anatomy program. More than 60% of participants stated that the program met their needs in terms of the level of anatomy knowledge, and that the topics were of interest, well presented and relevant to their teaching. This study may provide useful information for future community-university studies in this area.
Developing peacebuilding skills among civil society organisations in Zimbabwe
Authors:   , Makwerere David
Published: July 2022

Local peacebuilding practices require a systematic and reflective analysis in order for them to bring an impact. Successful peacebuilding pivots on the development of a set of skills to attend to the challenges presented by the conflict. The study was inspired by an observation that the emergence of CSOs working on peacebuilding in Zimbabwe was happening in a context where there was no proper training and organisational capacity development. Using an action-research design, and a case study of two CSOs operating in Bindura and Mazowe Districts in Mashonaland Central Province in Zimbabwe, the study involved a sample group of fifty-seven participants, and included a core Action Research Team (ART) of twelve participants to initiate the process of capacity development related to peacebuilding in Zimbabwe. Interviews, Focus Group Discussions, Document studies were used in a triangulation approach to enhance validity and reliability of the process. The preliminary assessment revealed that the peacebuilding environment in the two districts is highly polarised. There is a combination of both direct and indirect violence in the area. The state as well as traditional institutions are active perpetrators of both direct and indirect violence in the two district. The use of Local Peace Committees and the workshop method has not reaped the desired outcomes owing to the polarization. After a preliminary assessment of the peacebuilding environment in the area as well as a critique of the peacebuilding models being used by the two organisations, we then set out on a process of identifying strengths and weaknesses in both the programming as well as the delivery of the projects in the communities. A series of focus group discussions and organisational document analysis of the two organisations, we eventually agreed on the development of a training module for the Action Research Team. Five thematic issues were identified as forming the basis of the intervention programme. The five thematic issues were on the conceptual issues of conflict, violence and peace in a local context, conflict analysis skills, conflict sensitive programming, culture, conflict and change and lastly basic counselling skills for peacebuilders. A three-day training workshop was then held in order to develop capacity relating to the thematic issues. The short term evaluation of the intervention showed that the training was successful as the participants had already started implementing some of the new knowledge and skills.

Partindo da suposição de que há favorecimento do fator visual e consequente distorção perceptiva em cenas de divulgação de marcos turísticos e suas respectivas cidades, objetiva-se identificar a aproximação conceitual de definição de variáveis analíticas para enfrentamento dessas dificuldades. Com abordagem qualiquantitativa, foram utilizadas técnicas de revisão sistemática de fontes secundárias a partir de levantamento bibliométrico, associando assuntos centrais (fotografia, arquitetura e cidade), secundários (imagem, monumento, urbano e cenário) e transversais (turismo e sustentabilidade). Os resultados contemplam 30 artigos selecionados por critérios específicos para interpretação detalhada, consubstanciada em painéis de variáveis de análise, que subsidiam, além de ponderações sobre a temática, a corroboração da hipótese formulada, demonstrando a capacidade de indução de cenários pela fotografia, dissociada de percepções sensoriais e de experiências pessoais. Conclui-se, todavia, que as imagens de fenômenos turísticos nas áreas da arquitetura e do urbanismo são de relevante importância para a gestão sustentável das cidades.
