Published: January 2021

The use 802.11 wireless-based network services have become one of the most widely used network services, this will be directly proportional to the security holes that are in the wireless network. The rise of access rights theft in wireless networks is due to the large number of software and tools available on the internet to read encryption in wireless security. To minimize the occurrence of theft of access rights in wireless networks can use a layered security system by implementing security Hotspot login and MAC Address Filtering. This layered wireless network security is able to block users who try to access the network. This is because the wireless network security system has verified access rights 2 (two) times by matching the username and password in the hotspot login with the physical address or MAC address of the client. From the research results obtained by clients who use a username and password with different devices can not access the computer network. So every client who wants to connect to the internet network must use a device that has registered its MAC Address and in accordance with user access rights and passwords in the Hotspot login

Forest fire detection system is one of important tools in preventing and mitigating forest and land fires. In Indonesia, the detection of forest and land fires relies on hotspot information captured from satellites. However, the location obtained by the satellite has a horizontal error of 2 km from the ground check data. Therefore, these information are less relevant to the actual location.
In this research, an android app is proposed to extract Exchangeable Image Format (EXIF) photo metadata. The metadata has image information such as latitude and longitude, to obtain the location of forest fires reported by the application user. In addition, this research implemented one of the image processing methods to classify fire and smoke in images of fires. Color filtering method is used based on the color space of Red Green Blue (RGB), Hue Saturation Value (HSV) and YCbCr. This classification process aims to ease the burden on the admin in confirming user reports.

The results of the fire and smoke classification process are described using a confusion matrix. This matrix  produces an accuracy rate of 75%, a precision of 80% and a recall of 80% for a fire classification and an accuracy of 70%, a precision of 92% and a recall of 87% for smoke classification. There are 25% and 30% of misclassified data of fire and smoke. This is because the color filtering method classifies each color pixel from the image, therefore many pixels that are not classified as fire or smoke images are classified because there are other objects that have a range of colors to classify fire and smoke

Published: January 2021

In this article analyzes aspects of religion and state relations in Iran and Turkey. In order to open relations between the state and religion, analyzed the features of the manifestation of religious elements in the power system of these countries, including the country's Constitution and legislation regulating the sphere of religion, the activities of religious parties and religious communities. In addition, special attention was paid to the geographical location of the two countries, ethnic and religious composition, and cultural history. Among Islamic countries, Iran and Turkey have a number of differences in religious and state relations compared to other Muslim countries. Therefore, it is important to focus on the models of these two countries when studying the world experience of relations between religion and the state in a comprehensive way. This is especially important for Kazakhstan, which is moving in a secular direction. In the structure of the state administration of Iran, the influence of the religious corps «Valiyat Faqih» is predominant. In Turkey, on the other hand, the religious administration of Dianet is subordinate to the presidential administration. In Iran, religious parties are politically active, while in Turkey, political parties are not allowed to use any religious elements. However, despite these features, both countries are recognized in the world as States that give priority to the Muslim religion. Since the article is aimed at uncovering the specifics of state-confessional relations in Iran and Turkey, structural and functional and comparative analysis methods have been used in the study.

The article deals with the problem of professional training specialists in tourism. The relevance of the research is that recently the role of knowledge in the process of training future specialists in the sphere of tourism has changed. In the current socio-economic context, in order to fulfill the order of society for high-level future specialists in the sphere of tourism, graduates of higher educational institutions are forced to possess not only an extensive theoretical base in their specific specialty, but also certain meta-subject knowledge. However, mere knowledge ownership is no longer sufficient in the context of the development of the international labor market. The problem of the need for the formation and development of a new quality of education appears, the updated content of which will be based on key competencies. In this case, the key competence is defined as a mandatory competence, because it corresponds to the conditions of implementation, which are not limited, not too specific, but are universal within certain limits. In this regard, a survey of future tourism experts was conducted on the subject of their perception of the importance of forming competencies. The results of the survey are described in this article.

Since the middle of the XIX century, ancient inscriptions written on silver bowls, bracelets, and bronze mirrors have been found in large numbers on the territory of Kazakhstan from the surface of the earth and archaeological excavations. Currently, the number of such Turkic runic inscriptions is increasing every year. The first Kazakh scientist who found and tried to reveal their meanings was A. Amanzholov. He named such inscriptions found from Kazakhstan, summarizing them by local values as Irtysh, ili, Syrdarya and Ural. The most valuable was the inscription on the silver bowl, found as a result of archaeological excavations from the Issyk mound. Linguists who came from the Academy of Sciences of the former Soviet Union made a categorical conclusion, without presenting any arguments, that the Issyk inscription is in the Iranian language, and cannot be read in the Turkic languages. But Kazakh researchers, not agreeing with this conclusion, began to read this inscription in the ancient Turkic language. Comparing and analyzing these studies, we published our reading in 1993. After that, until 2009, we updated and supplemented our readings three times. One of the Irtysh inscriptions tells about the danger of vodka and wine for human life. And the second tells about the coolness inside the mountain gorge. In the inscriptions found in the Zhetysu area, special attention was paid to hunting. They describe the sensitivity and extreme caution of the mountain goat. The Talgar inscription speaks of yarn and the spinning profession. In one of the aulieatinsky inscriptions, on the seal is written the phrase «my word», and on a large stone about the immensity of the country of the Karakhanids. And the Syrdarya inscription mentions the greatness of the Syrdarya river.

We propose a plausible conjecture about what goes on inside the black box of the Leontief-Liebig production function. The approach is based on an idea that the conversion of resources into a final product in an industrial supply chain occurs in much the same manner as does the conversion of substrates into different molecules in an enzyme-catalyzed biochemical reaction. A bottleneck principle is derived according to which at any moment the steady-state output of a supply chain is completely controlled by a single factor of production. The reduction of complexity is made possible owing to the sigmoid inputresponse of an individual node in the chain.

This study aims to explore how the role of an accountant who migrates to interpret and apply the Makassar version of the Pappasang Tu Riolo values. The research was motivated by the presence of nomads with an educational background of accountants who came from the Makassar tribe which researchers called Green Winged Accountants with the cultural approach of Pappasang Tu Riolo. The approach used in this research uses interviewing techniques that cannot be separated from the eight codes of ethics for accountants in Indonesia. The findings of this study, when linked with the Makassar version of the accountant's code of ethics and culture of Pappasang Tu Riolo, have three main points, namely, first, responsibility to God, meaning that everything that is done must be done based on his orders and stay away from prohibitions. Second, accountability to others ensures that they do not differentiate as social beings who are still in a productive work and cultural order, but must maintain harmony and dignity in society. Third, responsibility to oneself, which means ensuring that every time someone does a job, he fulfills his obligations or keeps a predetermined commitment.

QUEM SÃO OS SEM-TERRA? UMA QUESTÃO RELEVANTE PARA A COMPREENSÃO DA LUTA PELA TERRA NO BRASIL
Authors: Ramalho Cristiane Barbosa
Published: January 2021

Propomos, neste trabalho, um tema que versa sobre a questão da identidade dos semterra. Estamos desenvolvendo esse projeto de pesquisa desde agosto de 1997, tendo como parâmetros: bibliografia selecionada, colóquios no qual foram debatidos temas pertinentes ao projeto e realização de pesquisa de campo. É com base nesses procedimentos que procuramos os subsídios que nos auxiliassem na compreensão de quem são os sem-terra: personagens que conquistam frações de territórios no campo brasileiro, lutam contra a expropriação territorial efetuada por grandes proprietários, grileiros e empresários; contra a exploração econômica que se concretiza na ação das grandes empresas capitalistas que subjugam o fruto do seu trabalho, e na política econômica do Estado que cria e garante as condições dessa sujeição. É no tocante à essa consideração que o texto estrutura-se: num primeiro momento realizamos uma reflexão atinente ao processo de luta pela terra que expressa a condição em que o trabalhador encontra-se no movimento contraditório da relação capital x trabalho. Numa segunda parte, explicitamos o processo de grilagem das terras do Pontal do Paranapanema; a espacialização e a territorialização do MST na região do Pontal, para que possamos compreender os conflitos por terra que envolvem o Estado e os latifundiários-grileiros. Na terceira parte discutimos quem são os sem-terra organizados no MST, que representam os expropriados do modo de produção capitalista, e que reivindicam o uso social da terra, a reforma agrária e a cidadania. Dessa maneira, é nosso objetivo praticar o exercício da leitura geográfica, vislumbrando refletir o tema e contribuir para o seu desenvolvimento.

Objectives: In 2013, the World Health Organization (WHO) recommended new criteria for diagnosing gestational diabetes mellitus (GDM). Our study aimed to compare the incidence of GDM and its complications among Omani pregnant women using the new diagnostic criteria compared to previous criteria published in 1999. Methods: This retrospective cohort study was conducted between January and December 2016 at the Bawshar Specialized Polyclinic in Muscat, Oman. A total of 613 Omani women were included in the study. Baseline maternal characteristics such as age, body mass index, parity, and socioeconomic status were recorded in addition to maternal and neonatal outcomes. Results: Based on the current diagnostic criteria, the incidence of GDM was 48.5% (n = 297); however, this dropped to 26.4% (n = 162) when applying the old criteria. Moreover, rates of maternal complications including polyhydramnios (5.6% vs. 4.6%), pregnancy-induced hypertension (3.2% vs. 1.5%), and preterm delivery (3.2% vs. 1.5%) were slightly higher among women with GDM diagnosed using the latest criteria. However, these differences were not statistically significant. Neonatal complications were also slightly more frequent among the first group, without any significant differences. Conclusions: The incidence of GDM among Omani women rose dramatically when utilizing the latest WHO diagnostic criteria, owing to a lower fasting blood glucose cut-off value. In addition, a comparison of the frequencies of maternal and neonatal complications supports the validity of the new criteria. These findings should be taken into consideration by decision-makers in Oman when planning antenatal and postnatal services.

Este texto apresenta os resultados de uma pesquisa acerca da contratação da Falconi Consultores de Resultado por parte da Prefeitura de um município do estado do Rio Grande do Sul para atuar na área educacional. A investigação teve como objetivo analisar os possíveis impactos da consultoria na gestão das escolas da rede. Para tanto, realizou-se a análise de documentos orientadores dessa consultoria; identificou-se a configuração da empresa contratada e suas relações com outras entidades; e conduziram-se entrevistas com gestores de escolas da rede municipal. Como estratégia de coleta de dados, optou-se pela metodologia de etnografia de rede (BALL, 2014) e para o tratamento dos dados se utilizou a abordagem de análise de conteúdo (BARDIN, 2011). As análises mostraram que a realização da consultoria está vinculada às mudanças no papel do Estado, seguindo a lógica da Nova Gestão Pública (NGP), por meio da adoção de princípios gerenciais, evidenciados pelas ações da Falconi nas escolas, voltadas para a maximização de resultados.

Authors: Pan Wen , Liu Qing-Jun
Published: January 2021

Introduction

The aim of this study was to evaluate diagnostic performance of wireless fractional flow reserve (FFR) used in patients with coronary artery disease (CAD).

Material and methods

PubMed, Cochrane Library, Embase and Clinical trial.gov databases were searched by computer search and manual retrieval. The search terms included fractional flow reserve, quantitative coronary angiography, computational fluid dynamics and coronary artery disease. The meta-analysis was conducted with Stata12.0. Clinical outcomes included accuracy, sensitivity, specificity, positive likelihood ratio (+LR), negative likelihood ratio (–LR), diagnostic odds ratio (DOR) and area under the receiver operating curve.

Results

Nine studies comprising 2052 vessels were included in the present meta-analysis. The sensitivity, specificity, +LR, –LR, DOC and accuracy were 87% (95% CI: 83–94%), 88% (95% CI: 82–92%), 7.28 (95% CI: 4.78–11.08), 0.14 (95% CI: 0.10–0.21), 50.69 (95% CI: 25.22–101.88) and 0.94 (95% CI: 0.91–0.96) respectively. No significant publication bias was detected.

Conclusions

This meta-analysis suggests that the clinical performance such as accuracy, sensitivity and specificity of wireless FFR is good to detect stenotic lesions with pressure-wire measured FFR as a reference.

Introduction

The aim of the study was to investigate the changes in serum concentrations of nine vitamins in patients undergoing chemotherapy for lung cancer and explore their clinical values and influencing factors.

Material and methods

Patients receiving chemotherapy for lung cancer in our centre from February 2018 to May 2020 were enrolled in this study. Serum concentrations of the nine vitamins including vitamins A, D, E, B9, B12, B1, C, B2, and B6 were measured in all subjects, and the changes in the concentrations of these vitamins were compared before and after 2 cycles of chemotherapy. In addition, the potential correlations of serum vitamin levels with age, gender, pathological type, and disease status were analysed.

Results

In the 178 patients with lung cancer, there were different degrees of vitamin A, vitamin D, vitamin C, and in particular, vitamin B2 deficiencies. Before chemotherapy, the concentrations of vitamin A and vitamin C were significantly different between males and females and among patients in different clinical stages (both p < 0.05), the concentrations of vitamin C and vitamin B2 significantly differed among different pathological types of lung cancer (p < 0.05), and vitamin D level was significantly related to the disease status (p < 0.05). In addition, the proportion of vitamin B2 deficiency differed significantly among different pathological types (p < 0.05). There were significant differences in the concentrations of vitamins D, C, and B2 before and after chemotherapy (all p < 0.05). There was a correlation between the change of serum vitamin B1 concentration before and after chemotherapy and the change of body mass index (p < 0.05).

Conclusions

During chemotherapy, lung cancer patients are more likely to develop vitamins A, D, C, and B2 deficiencies. Different vitamin deficiencies are related to gender, clinical stage, pathological type, and disease status. Vitamin determination and reasonable supplementation of nutrients in patients undergoing chemotherapy for lung cancer can help improve the nutritional status and increase chemotherapy tolerance.

Introduction

Introduction: Helicobacter pylori infection is accepted as the leading cause of chronic gastritis, ulcer disease and gastric cancer, with an important impact on health care burden, especially in countries with a high prevalence of infection. The aim of the study was to investigate the influence of H. pylori infection, medication, associated medical conditions or social habits on endoscopic ulcer occurrence in the compensated type 2 diabetic population.

Material and methods

Two hundred and sixty type 2 diabetic patients investigated on endoscopy (57 patients with peptic ulcer and 203 controls) with a complete set of biopsies, demographic and medical data were enrolled.

Results

On univariate regression analysis, H. pylori infection (42.1% vs. 35.5%, p = 0.359) or a history of peptic ulcer (61.4% vs. 61.6%, p = 0.981) was not a predictor for ulcer on endoscopy in the diabetic population, and heartburn was more frequent in diabetics without ulcer (21.2% vs. 8.8%, p = 0.033). Anemia was the best predictor for ulcer on endoscopy in both diabetics with (p < 0.001, OR: 4.77, 95% CI: 2.02–11.28) and without (p = 0.027, OR: 2.76, 95% CI: 1.10–6.91) chronic proton pump inhibitor (PPI) therapy. In diabetic patients on PPI more than 1 month anticoagulants – acenocoumarol or low-weight molecular heparin (p = 0.038, OR: 2.37, 95% CI: 1.04–5.40), low-dose aspirin 75–125 mg/day (p = 0.029, OR: 2.61, 95% CI: 1.08–6.28) and alcohol consumption (p = 0.015, OR: 2.70, 95% CI: 1.19–6.13) were predictors for ulcer on endoscopy.

Conclusions

In diabetic patients, anemia is the most important predictor for ulcer on endoscopy, but not H. pylori or digestive symptoms, while low-dose aspirin or anticoagulant therapy and alcohol consumption are the most important predictors for ulcer in diabetics on chronic proton pump inhibitor therapy.
