A REVIEW ON STEGANOGRAPHY AND DATA HIDING IN QR CODE
Authors: M P Shreya , R Dr.Anitha
Published: March 2022

In comparison to 1D barcodes, a two-dimensional matrix is regarded as a Quick-Response (QR) code which is a programme that contains a vast quantity of data. QR codes offer quick scanning, omnidirectional reading, and a variety of other benefits, such as error correction. Barcode scanners can readily reveal the content of QR codes. In reality, however, gratified QR apps could contain confidential information, like an electronic-ticket or an electronic-coupon. To safeguard quick response essence from unauthorized users or scanners, it should be password protected. We'll look at QR codes and different sorts of QR barcode steganography mechanisms in this article.

Authors: S Arpitha , H D Dr.Phaneendra
Published: March 2022

NoSQL database management solutions are a departure from standard relational database management systems (RDBMS). Non-tabular NoSQL databases store data in a distinct way when compared to relational database tables. The data model of NoSQL databases is used to classify them. The most popular types are document, key-value, wide-column, and graph. They feature customizable schemas and can easily handle large amounts of data as well as significant user loads. They have adaptable schemas and can handle big amounts of data and high user loads with ease. Furthermore, their data models' flexibility and ease of use, in comparison to the relational model, can faster the development, especially in the field of cloud computing. This paper discusses the benefits of NoSQL databases, such as the ability to handle large volumes of data at high speeds with a scale-out architecture, the ability to store unstructured, semi-structured, or structured data, and the ability to easily update schemas and fields, making them developer friendly. Furthermore, this paper discusses the downsides, such as the lack of reliability features found in Relational Databases.

With the urban and industrial growth, many evolving countries suffer from excessive air pollution. The growing concern about air pollution has been raised by the government and people because it affects individual’s health and sustainable development globally. Several factors influence Air Quality and we must use all of them to interpose and forecast air pollution for the whole city. Thearticle suggested a novel deep learning CBGLSTM model for air quality forecasting based on 1D CNN, Bi-GRU, and Bi-LSTM neural networks. The model has experimented on the PM2.5 dataset taken from UCI Machine Learning Repository. The results demonstrate that compared to other traditional deep learning models, the CBGLSTM model gives better prediction performance and less error.
Sulawesi endemic tubers and perimedular flour properties an initial
consideration for alternative sources for food starch ingredient
Authors: Moko E.M. , Rahardiyan D. , Ngangi J. , Yalindua A.
Published: March 2022

North Sulawesi is located in the North-Eastern regions of the Indonesian Archipelago. As
it is with most parts of Indonesia, North Sulawesi is dependent on rice as their staple food.
Not all islands within the North Sulawesi cluster of islands can grow paddy or corn for
their carbohydrate needs or starch ingredients in their diet and must have them shipped
from other places with the dire consequences of transportation costs. The endemic
biodiversity of these islands also has many plants with the potential as an alternative food
carbohydrate source. This study was to explore these endemic plants for potential food
ingredients for starch replacements for rice and corn. The many diversities available for
these starch ingredients amongst them are tuber sources (Taro – Colocasia esculenta,
Dalugha – Cyrtosperma merkusii, Gembili – Discorea esculenta and Banggai – Discorea
alata) and perimedular sources (Sago Tanah and Sago Baruk). Many studies have
researched these plants individually in various originating from many other parts of the
world, but not many have made a head-to-head comparison and explored the potentials of
these underutilized plants as starch food ingredients. This study extracted starches of these
plants in a standardized manner and compared the properties side-by-side. These plants
were found to be potentially healthy alternatives to rice as functional food starch with
lower digestibility which would lead to lower GI staples, especially for the livelihoods of
North Sulawesi coastal dwellers.

Centrifuge modeling of temperature effects on the pullout capacity of torpedo piles in soft clay
Authors: Ghaaowd Ismaail , McCartney John , Saboya Fernando
Published: March 2022

This study presents the results from centrifuge modeling experiments performed to understand the effects of temperature changes on the vertical pullout capacity of scale-model torpedo piles embedded in soft clay layers. The model torpedo pile is a pointed stainless-steel cylinder with fins at the top, installed by self-weight to the base of a clay layer using a stepper motor. An internal electrical resistance heater was used to control the pile temperature. The torpedo pile was first heated until the temperature and pore water pressure of the surrounding clay layer stabilized (drained conditions), after which the torpedo pile was cooled. Pullout tests performed on torpedo piles indicate that allowing drainage of excess pore water pressures induced by heating to different temperatures followed by cooling leads to an increase in axial pullout capacity with maximum temperature but does not affect the pullout stiffness. Push-pull T-bar penetration tests performed before and after pile heating indicate that an increase in undrained shear strength of the clay occurs near the torpedo pile, and post-test gravimetric water content measurements indicate a greater decrease in void ratio occurred in the soil layers heated to higher temperatures. The pullout capacity of the torpedo pile was found to follow a linear trend with maximum pile temperature change, but with a smaller slope than that observed for end-bearing energy piles tested in previous studies in the same clay.

Reformasi Katalitik Nafta untuk Pembuatan Bensin dan Aromatik dengan Katalisator Reforming Bifungsional
Authors: APU A.S Nasution
Published: March 2022

Meningkatnya kebutuhan bensin berangka oktana tinggi dan hidrokarbon aromatik rendah sebagai salah satu bahan baku utama industri petrokimia telah memacu pengolahan minyak bumi untuk meningkatkan jumlah jenis kedua produk tersebut. Reformasi dari fraksi nafta dengan bantuan katalisator bifungsional adalah salah satu proses katalitik untuk pembuatan reformat yang berangka oktana tinggi dan juga sumber aromatik rendah seperti benzena, toluena dan exylena atau BTX". Schubungan dengan kandungan hidrokarbon paraffin dan naftana yang tinggi dari umpan napta tersebut, maka konversi kedua jenis hidrokarbon tersebut dengan bantuan katalis reformasi bifungsional menjadi hidrokarbon aromatik adalah reaksi utama dari proses reformasi katalitik. Untuk meneliti tỉngkah laku katalisator refomasi bifungsional pada konversi hidrokarbon parafin dan naftana menjadi hidro karbon aromatik, maka suatu percobaan telah dilakukan dari katalik reformasi hidrokarbon murni (n.heksana, n.heptana, n.oktana dan metilisklopentana) dan umpan fraksi nafta dengan memakai dua jenis katalisator reformasi (mono dan bi-metalik) pada kondisi operasi: suhu dari 450'sampai 510 C, tekanan: dari 5 sampai 30 kg/cm2 dan perbandingan H/HC = 6 mol/mol dengan memakai alat catatest unit yang diopersikan secara kontinu. Berdasarkan hasil pengamatan menunjukan bahwa aromatisasi parafin diamati lebih rendah dari pada aromatisasi naftana, dan tingkah laku katalisator re- forming bi-metlik untuk aromatisasi paraffin dan neftana tersebut adalah lebih unggul dari katalisator reforming monometalik.

ABSTRACT
The increasing number of vehicles in Jakarta has the potential to increase air pollution, especially on protocol roads. However, during the COVID-19 pandemic, large-scale social restrictions (PSBB) were imposed in Jakarta, which made work activities and learning processes carried out online. These social restrictions cause a decrease in vehicle activity, including at Universitas Pertamina Areas in Jakarta. The decreasing number of this activity certainly affects the ambient air quality. Therefore, ambient air quality measurements were conducted at Universitas Pertamina Areas during the COVID-19 pandemic. The parameters observed included SO2, NO2, O3, TSP, PM2.5, and NH3. This research showed that during the COVID-19 pandemic, the measured air parameters, namely SO2, NO2, O3, TSP, and PM2.5, met the quality standards based on the Government Regulation of the Republic of Indonesia Number 41 of 1999 concerning air pollution control. Also, NH3 parameters had met the Decree Minister of Environment Number: KEP-50/MENLH/11/1996 concerning odor level standards.

Published: March 2022

The purpose of this research is to develop a portfolio assessment model to increase the self-regulated learning of students. With this product, it is hoped that it can become a reference for transformation from traditional assessments to increase self-regulated learning and achieve good learning outcomes. This research is development research to produce a product portfolio model. The results of the research that has been done, show that teachers at MAN 1 Bandar Lampung have difficulty in assessing the appropriate assessment for students and self-regulated learning students. Teachers have not been able to assess things other than traditional assessments, which only judge from the results and results of the exam so that students can evaluate the learning and assessments that have been done. This condition also affects the low self-regulated learning of students from students who rarely archive what has been given by the teacher. The portfolio assessment model has not been implemented in schools so that teachers and students expect a portfolio model so that it can increase the self-regulated learning of students. This research produces a portfolio assessment model and shows a very well-designed and relevant portfolio assessment model in economics learning.

Published: March 2022

Since Covid-19 was declared a pandemic, educational technology has become trended by playing E-learning. Teachers and students are forced to transform from traditional classes into E-classrooms. However, full e-learning did not give students a massive impact yet, and lately, they have become less motivated since it provided no real communication (Mese & Sevilen 2021).�Integrating face-to-face learning (direct interaction) and technology-based learning (digital communication) becomes promising (Garrison &Vaughan, 2008; Rianto, 2020). This study explored the perspectives of 3 pre-service teachers and 27 students towards the blended learning (BL) practices in the EFL context. The setting was the English education department, Universitas Borneo Tarakan. The data were collected using online interviews to gain in-depth information. The findings uncovered that the teachers and students gave positive perspectives to apply this model to the new normal. In addition, BL could reshape the teachers' roles by applying multiple technology use in the teaching and learning process. BL �was also able to broaden students' learning experience and provide them with a technology-based world. This study highlighted some implications, including the need for pre-service teachers' professional development that ultimately will help teachers assist students in succeeding in blended learning.
Engineering students� English public speaking: Why is it a nerve-wracking experience?
Authors: Nangimah Musrifatun
Published: March 2022

Mastering English public speaking is required for Engineering students to contribute to the Ministry of Education�s internationalization policy that is manifested in the university�s regulation.�However, English public speaking has become a nerve-wracking experience for L2 learners. This research aims to explore Engineering students� English public speaking anxiety and its causes. The explanatory sequential design is applied. The online-based survey was conducted on 197 first-semester students and semi-structured interviews with 8 most anxious participants. The triangulation data analysis of quantitative and qualitative phases was carried out. The results illustrate that students experience moderate to low public speaking anxiety levels. The reasons for public speaking anxiety are linguistics problems, inhibition, lack of speaking practice, the difficulty for sentence construction from L1 into the target language, fear of peer negative feedback and being assessed, and dealing with unfamiliar topics as well as speaking delivery driven thoughts. Furthermore, teachers' reflexive identity and the appointment system used to determine public speakers become additional pressures. These findings can be used as valuable consideration to design appropriate speaking pedagogy, especially in the context of English for non-English major programs. Recommendation for future research is discussed.

Secreted Frizzled – Related Protein 4 y el cáncer de mama
Authors: Ramírez Tortosa María del Carmen , Gálvez-Navas José María , Pérez-Ramírez Cristina
Published: March 2022

Introducción: el correcto funcionamiento y la supervivencia de la célula vienen mediados por multitud de procesos clave. El delicado equilibrio que se requiere entre dichos fenómenos hace que un error en los mecanismos de control desencadene el inicio de la carcinogénesis. Dentro de las rutas metabólicas encargadas de su regulación se encuentran las vías de señalización del Wnt. De esta forma, aquellas moléculas que intervengan en dichas vías presentarán un papel clave para el estudio de la patología, entre las que destaca secreted Frizzled – Related Protein 4 (sFRP4).

Método: se ha llevado a cabo una búsqueda bibliográfica en bases de datos de referencia, como es el caso de Medline, Scopus o Web of Science.

Resultados: a sFRP4 se le ha otorgado el papel de modulador negativo de las vías de Wnt debido a su capacidad de competir por los ligandos Wnt y evitar el inicio de dichas rutas. Por lo tanto, sFRP4 será esencial en el control del inicio y desarrollo del cáncer en aquellos tejidos donde se exprese la proteína, dentro de los que se considera el tejido mamario.

Conclusiones: los recientes estudios acerca de la implicación de sFRP4 en el desarrollo de diversas patologías, justifican que la proteína haya captado la atención en los últimos años. De esta forma, se puede afirmar que sFRP4 presenta un interesante potencial como biomarcador en el tratamiento, diagnóstico y pronóstico del cáncer de mama, entre otras enfermedades.

Regional resilience is typically described as the ability of a region to withstand shocks and recuperate from various crises. Τhis paper examines the quantitative aspect of tourism resilience and focuses on tourism employment. The aim is to highlight the distinct potential of each Greek region to recover from the ongoing pandemic, based on its calculated tourism resilience. This empirical research uses secondary data and calculated indices developed for evaluating regional resilience. Statistical data from official sources provides information regarding regional employment with focus on tourism. Preliminary findings show that important differences are evident between regions regarding their resilience and their subsequent ability to recover from ongoing crises. Estimated resiliency is not always accompanied by a corresponding recovery, especially on the tourism sector. Regions with a strong tourism industry seem to have a stronger resilience than regions that base their development on other industries and this is an indication but at the same time shows the potential of tourism for the development of a region.

Influence of the European Union (EU) on International Maritime Organization (IMO) about the Market-based Measures on Emissions
Authors: Kırval Levent , Çalışkan Ufuk Yakup
Published: March 2022

Market-based Measures (MBM), a catalyst for new and effective technologies, can be highly rewarding for the shipping industry on its way to reach 50% decarbonization by 2050. To regulate emissions and improve energy efficiency in maritime transportation industry, MBMs are in focal point at the decision-taking level both for International Maritime Organization (IMO) and European Commission (EC). EC included shipping into European Union’s (EU) existing Emission Trading Scheme (ETS). However, IMO’s scheme will be functional after 2023 and decision of an MBM is not finalized yet. The motivation of this paper is to analyze viable MBMs under the Initial IMO Greenhouse Gases (GHG) Strategy based on their superiority and evaluate the influence of EU’s policy implementation on global shipping industry. The issues such as economic implications, feasibility, social and environmental responsibilities, and harmony of the policy are included to the manuscript to assess the success of the MBMs. Main concerns and thoughts revolving around EU ETS; such as economic implications of a taxation, the existence of an administrative body for shipping in EU ETS, carbon leakage caused by high taxation, voyage evasion of emissions by not delivering goods to distant areas, emergence of a fraud-proof and more secure system with an administrative body, success factors of EU ETS after 16 years, full certainty of reducing emissions rather than incentives to reduce emissions, monitoring and reporting schemes; are discussed to bridge the issue with EU’s reasonings.
Effects of Mucilage on Safety Navigation in the Turkish Straits
Authors: Usluer Hasan Bora
Published: March 2022

Mucilage, which has surrounded the Marmara Sea and the Turkish Straits in particular for the last few months, is a gel-like and slippery mass of microorganisms that are mostly clumped together and cover large areas, consisting of proteins, carbohydrates, and fatty acids released out of the body by single-celled organisms under stressful environmental conditions. Although the Turkish Straits sea area is the waterway connecting the Caspian Sea and the Mediterranean Sea, it is essential to transition for marine species. The mucilage effect on the filtration of the ship systems is caused by the seawater used by the ship's cooling systems during the passage through the straits. Due to the protection of local and global sea areas, a high level of attention is needed, especially on significant waterways located on the transit route of ships moving to many ports of the world serving global transportation such as the Turkish Straits. The study is trying to describe Mucilage's effects on ships during sailing at the Turkish Straits.

Published: March 2022

The landcover has most essential impact on the climatic condition of any region. The rapid urbanization induces key changes into the climatic condition of any region. This changing pattern of urbanization has induced micro level climatic changes with demographic variation as the key factor. In this study we analyzed the effect of landcover classes on the LST in the Peshawar for 1990. 2000, 2010 and 2019. The results revealed that the builtup area has been increased from 14.20% to 20.22% during 1990 to 2019. The results also show that the LST values are between the ranges of 25°C to 36°C. The air temperature and LST have very compromising correlation. The hype and increase in the UHI zones are resultant to rapid urbanization and expansion of Old Municipal Corporation with initiation of developmental projects in the area. This study will help urban planners and decision makers in landuse planning and management to mitigate the increase in LST with the replacement of possible impervious surfaces with green built and road side plantation for comfortable urban environment.
Defining The Relationship Between The Diameters of The Points Used in 2D Test Platforms and The Parameters Obtained from Camera Calibration

Published: March 2022

With the developing technology in recent years, there has been a significant increase in 3D spatial data needs and data production. 3D spatial data occupy an essential place in almost every field. As a result, there is a need for 3D spatial data production and the produced data's reliability. Like all spatial measuring equipment, cameras, which are data production units used in photogrammetry, must also be calibrated to produce reliable data. Calibration for non-metric cameras is critical to ensure that the measurements made are of high accuracy and at standards acceptable to everyone. In this study, to determine the factors affecting the calibration, terrestrial photogrammetric images were taken with a Canon EOS 600D non-metric camera with different point diameters on the calibration paper. These images were evaluated in the camera calibration software, and the photogrammetric result accuracies were investigated. The effects of the point diameters on the camera calibration paper on the calibration results have been observed. For both calibration papers, A4, A3, A0 sizes were printed and calibrated. As a result of the printouts, as can be predicted, the largest point sizes are A0, which has the largest paper size, and according to the results, it was seen that the highest accuracy was achieved in the A0 dimension. The relationship between the accuracy obtained in the calibration process and the point diameters in the test area was examined in this study. When the 144-point test area presented by the software is printed in A0 size, the point diameters were measured as 1.00 cm. In this study, calibration processes were performed as 1.00 cm, 1.20 cm, 1.40 cm, 1.60 cm, 1.80 cm and 2.00 cm by enlarging the point diameters by 20%, and more accurate results were obtained more easily than other paper sizes and calibration methods. As a result, since the calibration of the device to be used in the studies directly affects the accuracy of the model to be obtained at the end of the study, it is necessary to take the maximum accuracy obtained in the calibration process. In this research, the calibration process's highest accuracy is aimed and how the calibration process can be performed more effortless and more accurately by increasing the size of the point diameter on the test area.

Acomys cilicicus is a narrow range, endemic spiny mouse species of Turkey. Some issues have been uncertain about its distribution and status. In the study, we, therefore, aimed to identify species' spatial distribution and understand the impact of environmental factors on species. We used maximum entropy modeling to fulfill these purposes. The results showed that the distribution of the species is restricted in the coastal part of the study area, the human population is one of the severe threats for the species distribution, and the fluctuations of climatic conditions may adversely affect the species distribution. We hope that these outputs can be valuable for the species' conservation efforts and serve as a guide for both Acomys cilicicus and other narrowly distributed species

A política penitenciária encarcerada: prisão e segurança pública no Brasil
Authors: Vinholes Siqueira Lucas Ana Cláudia
Published: March 2022

The thesis aims at the penitentiary issue-understood as a distance between speeches and official practices of criminal enforcement- at its intersection with Public Security Policies. In the temporal perspective, it was delimited between 2000 and 2016, which includes three different governments: FHC, Lula da Silva and Dilma Rousseff. Such democratic governments were significant in the context of traditional paradigms in relation to Public Security and the four National Plans they produced were constituted in the corpus of the investigation. With support in the specialized national bibliography on Public Security in its recent configurations, this was recognized as an organizational field in tension. On the perspective of the prison issue as pertinent to this field, the approach was developed in terms of an already recognized field and another to be recognized. The relevance of the development of the thesis in a Postgraduate Program in Social Policy and Human Rights is not only due to being linked to the Research Line “Human Rights, Security and Access to Justice”, but above all because of the understanding that the Security is an individual as well as a social right, which requires public and social policies to focus on achieving full citizenship. The thesis contribution is projected in the tension of the Security policy field itself, in which the prison issue needs to be included with another commitment, free of the traps that make up its presence as only the final instrument of repression.
