Factors Concerning the Dynamics of Footbridges and Methods for Improving Pedestrians’ Comfort
Authors: Mircea Suciu , Delia Drăgan , Raluca Nerișanu
Published: March 2022

Pedestrian bridges are constructions that are part of the category Bridges, having the particularity that due to much lower loading as compared to that of road or railway bridges, their decks are much slenderer, and can be included in the category of light structures. In this paper several aspects regarding the dynamic behavior of the footbridge structures under the traffic actions correlated with the pedestrians’ comfort are presented. The comfort criteria depend of the frequencies and accelerations of the structure and have to be situated between certain limits. If the frequencies and accelerations of the structure are in the critical domains, measures to modify them have to be taken, some of them being presented in this paper as they are the most usually used.

Published: March 2022

The water quality of a lake is an important factor for human health. Since the pollution level of the Nokoué Lake (Benin) became a concern, the present study was carried out to better understand and manage the quality of the surface water of this lake, to reduce the risks to damage the population health and the ecosystem equilibrium. The objective of the present work is the statistical study of the pollutants concentration data using Principal Component Analysis (PCA) and clustering. The concentration of five pollutants, namely NO3
−, NH4
+, NT (total nitrogen), PO4
3−, and total phosphates (PT) were sampled on thirty-three sites of the Nokoué Lake and analyzed. Three principal components have been selected and the sites have been grouped in three clusters, one of them containing only the sites on Cotonou.
How to Ensure the Quality of Construction Works for Marine Platforms with Reference to Midia Gas Development Project - ANA Platform & Doina Well & Gas Treatment Plant -
Authors: Schiau Roxana Doina
Published: March 2022

The Midia Gas Development Project is a new offshore gas project which has been developed and built in the last 30 year in the maritime territory of Romania. Once completed, it will have the ability to cover around 10% of gas needs of Romanian population.

Currently there is about 10 Bcm of resources to be produced at a rate of about 1 Bcm per annum.

The infrastructure was thought to be used for the production of gas from the reservoirs of Ana and Doina, in the first place. But the long term vision of the project consists in converting the already existent infrastructure to develop green energy projects, such an offshore wind plant, solar panels fields or production of hydrogen, projects that may start time before decommissioning of the gas production platform.
Are iPhones Really Better for Privacy? A Comparative Study of iOS and Android Apps
Authors: Kollnig Konrad , Shuba Anastasia , Binns Reuben , Van Kleek Max , Shadbolt Nigel
Published: March 2022

While many studies have looked at privacy properties of the Android and Google Play app ecosystem, comparatively much less is known about iOS and the Apple App Store, the most widely used ecosystem in the US. At the same time, there is increasing competition around privacy between these smartphone operating system providers. In this paper, we present a study of 24k Android and iOS apps from 2020 along several dimensions relating to user privacy. We find that third-party tracking and the sharing of unique user identifiers was widespread in apps from both ecosystems, even in apps aimed at children. In the children’s category, iOS apps tended to use fewer advertising-related tracking than their Android counterparts, but could more often access children’s location. Across all studied apps, our study highlights widespread potential violations of US, EU and UK privacy law, including 1) the use of third-party tracking without user consent, 2) the lack of parental consent before sharing personally identifiable information (PII) with third-parties in children’s apps, 3) the non-data-minimising configuration of tracking libraries, 4) the sending of personal data to countries without an adequate level of data protection, and 5) the continued absence of transparency around tracking, partly due to design decisions by Apple and Google. Overall, we find that neither platform is clearly better than the other for privacy across the dimensions we studied.
Understanding Privacy-Related Advice on Stack Overflow
Authors: Tahaei Mohammad , Li Tianshi , Vaniea Kami
Published: March 2022

Privacy tasks can be challenging for developers, resulting in privacy frameworks and guidelines from the research community which are designed to assist developers in considering privacy features and applying privacy enhancing technologies in early stages of software development. However, how developers engage with privacy design strategies is not yet well understood. In this work, we look at the types of privacy-related advice developers give each other and how that advice maps to Hoepman’s privacy design strategies.

We qualitatively analyzed 119 privacy-related accepted answers on Stack Overflow from the past five years and extracted 148 pieces of advice from these answers. We find that the advice is mostly around compliance with regulations and ensuring confidentiality with a focus on the inform, hide, control, and minimize of the Hoepman’s privacy design strategies. Other strategies, abstract, separate, enforce, and demonstrate, are rarely advised. Answers often include links to official documentation and online articles, highlighting the value of both official documentation and other informal materials such as blog posts. We make recommendations for promoting the under-stated strategies through tools, and detail the importance of providing better developer support to handle third-party data practices.
SoK: Plausibly Deniable Storage
Authors: Chen Chen , Liang Xiao , Carbunar Bogdan , Sion Radu
Published: March 2022

Data privacy is critical in instilling trust and empowering the societal pacts of modern technology-driven democracies. Unfortunately it is under continuous attack by overreaching or outright oppressive governments, including some of the world’s oldest democracies. Increasingly-intrusive anti-encryption laws severely limit the ability of standard encryption to protect privacy. New defense mechanisms are needed.

Plausible deniability (PD) is a powerful property, enabling users to hide the existence of sensitive information in a system under direct inspection by adversaries. Popular encrypted storage systems such as TrueCrypt and other research efforts have attempted to also provide plausible deniability. Unfortunately, these efforts have often operated under less well-defined assumptions and adversarial models. Careful analyses often uncover not only high overheads but also outright security compromise. Further, our understanding of adversaries, the underlying storage technologies, as well as the available plausible deniable solutions have evolved dramatically in the past two decades. The main goal of this work is to systematize this knowledge. It aims to: (1) identify key PD properties, requirements and approaches; (2) present a direly-needed unified framework for evaluating security and performance; (3) explore the challenges arising from the critical interplay between PD and modern system layered stacks; (4) propose a new “trace-oriented” PD paradigm, able to decouple security guarantees from the underlying systems and thus ensure a higher level of flexibility and security independent of the technology stack.

This work is meant also as a trusted guide for system and security practitioners around the majorchallengesin understanding, designing and implementing plausible deniability into new or existing systems.
User-Level Label Leakage from Gradients in Federated Learning
Authors: Wainakh Aidmar , Ventola Fabrizio , Müßig Till , Keim Jens , Cordero Carlos Garcia , Zimmer Ephraim , Grube Tim , Kersting Kristian , Mühlhäuser Max
Published: March 2022

Federated learning enables multiple users to build a joint model by sharing their model updates (gradients), while their raw data remains local on their devices. In contrast to the common belief that this provides privacy benefits, we here add to the very recent results on privacy risks when sharing gradients. Specifically, we investigate Label Leakage from Gradients (LLG), a novel attack to extract the labels of the users’ training data from their shared gradients. The attack exploits the direction and magnitude of gradients to determine the presence or absence of any label. LLG is simple yet effective, capable of leaking potential sensitive information represented by labels, and scales well to arbitrary batch sizes and multiple classes. We mathematically and empirically demonstrate the validity of the attack under different settings. Moreover, empirical results show that LLG successfully extracts labels with high accuracy at the early stages of model training. We also discuss different defense mechanisms against such leakage. Our findings suggest that gradient compression is a practical technique to mitigate the attack.
Understanding Utility and Privacy of Demographic Data in Education Technology by Causal Analysis and Adversarial-Censoring
Authors: Hasan Rakibul , Fritz Mario
Published: March 2022

Education technologies (EdTech) are becoming pervasive due to their cost-effectiveness, accessibility, and scalability. They also experienced accelerated market growth during the recent pandemic. EdTech collects massive amounts of students’ behavioral and (sensitive) demographic data, often justified by the potential to help students by personalizing education. Researchers voiced concerns regarding privacy and data abuses (e.g., targeted advertising) in the absence of clearly defined data collection and sharing policies. However, technical contributions to alleviating students’ privacy risks have been scarce. In this paper, we argue against collecting demographic data by showing that gender—a widely used demographic feature—does notcausallyaffect students’ course performance: arguably the most popular target of predictive models. Then, we show that gender can be inferred from behavioral data; thus, simply leaving them out does not protect students’ privacy. Combining a feature selection mechanism with an adversarial censoring technique, we propose a novel approach to create a ‘private’ version of a dataset comprising of fewer features that predict the target without revealing the gender, and are interpretive. We conduct comprehensive experiments on a public dataset to demonstrate the robustness and generalizability of our mechanism.
Who Knows I Like Jelly Beans? An Investigation Into Search Privacy
Authors: Kats Daniel , Silva David Luz , Roturier Johann
Published: March 2022

Internal site search is an integral part of how users navigate modern sites, from restaurant reservations to house hunting to searching for medical solutions. Search terms on these sites may contain sensitive information such as location, medical information, or sexual preferences; when further coupled with a user’s IP address or a browser’s user agent string, this information can become very specific, and in some cases possibly identifying.

In this paper, we measure the various ways by which search terms are sent to third parties when a user submits a search query. We developed a methodology for identifying and interacting with search components, which we implemented on top of an instrumented headless browser. We used this crawler to visit the Tranco top one million websites and analyzed search term leakage across three vectors: URL query parameters, payloads, and theRefererHTTP header. Our crawler found that 512,701 of the top 1 million sites had internal site search. We found that 81.3% of websites containing internal site search sent (orleakedfrom a user’s perspective) our search terms to third parties in some form. We then compared our results to the expected results based on a natural language analysis of the privacy policies of those leaking websites (where available) and found that about 87% of those privacy policies do not mention search terms explicitly. However, about 75% of these privacy policies seem to mention the sharing of some information with third-parties in a generic manner. We then present a few countermeasures, including a browser extension to warn users about imminent search term leakage to third parties. We conclude this paper by making recommendations on clarifying the privacy implications of internal site search to end users.
FP-Radar: Longitudinal Measurement and Early Detection of Browser Fingerprinting
Authors: Bahrami Pouneh Nikkhah , Iqbal Umar , Shafiq Zubair
Published: March 2022

Browser fingerprinting is a stateless tracking technique that aims to combine information exposed by multiple different web APIs to create a unique identifier for tracking users across the web. Over the last decade, trackers have abused several existing and newly proposed web APIs to further enhance the browser fingerprint. Existing approaches are limited to detecting a specific fingerprinting technique(s) at a particular point in time. Thus, they are unable to systematically detect novel fingerprinting techniques that abuse different web APIs. In this paper, we propose FP-Radar, a machine learning approach that leverages longitudinal measurements of web API usage on top-100K websites over the last decade for early detection of new and evolving browser fingerprinting techniques. The results show that FP-Radar is able to early detect the abuse of newly introduced properties of already known (e.g., WebGL, Sensor) and as well as previously unknown (e.g., Gamepad, Clipboard) APIs for browser fingerprinting. To the best of our knowledge, FP-Radar is the first to detect the abuse of the Visibility API for ephemeral fingerprinting in the wild.
Analyzing the Feasibility and Generalizability of Fingerprinting Internet of Things Devices
Authors: Ahmed Dilawer , Das Anupam , Zaffar Fareed
Published: March 2022

In recent years, we have seen rapid growth in the use and adoption of Internet of Things (IoT) devices. However, some loT devices are sensitive in nature, and simply knowing what devices a user owns can have security and privacy implications. Researchers have, therefore, looked at fingerprinting loT devices and their activities from encrypted network traffic. In this paper, we analyze the feasibility of fingerprinting IoT devices and evaluate the robustness of such fingerprinting approach across multiple independent datasets — collected under different settings. We show that not only is it possible to effectively fingerprint 188 loT devices (with over 97% accuracy), but also to do so even with multiple instances of the same make-and-model device. We also analyze the extent to which temporal, spatial and data-collection-methodology differences impact fingerprinting accuracy. Our analysis sheds light on features that are more robust against varying conditions. Lastly, we comprehensively analyze the performance of our approach under an open-world setting and propose ways in which an adversary can enhance their odds of inferring additional information about unseen devices (e.g., similar devices manufactured by the same company).

Published: March 2022

Infants experience rapid growth and development during their first year of life. The objective of the study was to investigate the early dietary habits of Latvian infants and their relation to iron metabolism. The study was composed of Study A “Research on eating habits of infants living in Latvia” (n = 344) and Study B “Research on the association between eating habits of infants living in Latvia and iron metabolism” (n = 73). 89% of infants (n = 18) were breastfed (BF) in the first month, and 21% (n =15) were exclusively BF for the first six months. The average age for introducing complementary food was five months. Iron intake was on average 7.4 mg. Iron deficiency (ID) was in 9.6% (n = 7) and iron deficiency anemia (IDA) in 4.1% (n = 3) of infants. The blood iron level was lower in 30% (n = 8) of infants fed with cow’s milk. For infants who obtained iron predominantly from non-animal products, serum ferritin (SF) was within normal range. SF was within the normal range for 93% (n = 26) of infants who did not consume legumes. Dietary habits of infants in Latvia partly correspond to the guidelines. 63% of infants did not consume enough iron from food and ID was observed in 9.6% of infants and IDA in 4.1%. A lower iron level in blood occurred in breastfed infants and in infants for whom cow’s milk was introduced at an early stage; a lower mean corpuscular volume level was observed in infants whose exclusive breast-feeding continued for at least the first four months; lower SF occurred in breastfed infants, in at least the first four months for exclusively breastfed infants, and in infants for whom whose legumes had been introduced in diet. A higher level of soluble transferrin receptors was observed in infants who were not first-born.

Published: March 2022

Nowadays available products for enteral nutrition are supplemented with synthetic ingredients. The effectiveness of these products is undeniable in the medical industry, but there is concern about bioavailability of synthetic vitamin and mineral compounds in comparison to naturally occurring ones. The aim of this study was to create plant-based formulations for enteral tube feed and to determine their bioactive compound and mineral compound concentration in comparison with the values recommended by the European regulations for special medical purpose food that is not meant to satisfy the nutritional requirements of infants. For this study, five enteral tube feed formulas were made from fruit, berry, and vegetable semi-finished products with added whey protein isolate, canola oil, cod liver oil, iodised salt, and ascorbic acid. The samples were thermally processed and concentration of vitamin C, total carotenes, total phenols and mineral compounds: P, K, Na, Ca, Mg, Fe, Mn, Zn, Cu and Se was determined. All samples showed < 20 mg·kg−1 per sample of Se, and also concentration of Zn was under the (EU) 2016/128 requirements. However, concentration of Mg (345.2 to 420 mg·100 kcal−1 of product) and K (29.2 to 39.2 mg·100 kcal−1 of product) exceeded the maximum levels. Also, the concentration of vitamin C exceeded the maximum, by average two times per sample, as L-ascorbic acid was added in response to previous experiments showing unsatisfying levels.

Published: March 2022

In the production of fermented cabbage, cell juice of cabbage is released, which is highly saturated in biologically active compounds, but is considered as a by-product. The aim of this study was to evaluate the quality parameters of dehydrated fermented cabbage juice using maltodextrin as a coating agent at various concentrations. In this experiment, fermented cabbage juice was used — spray dried on a horizontal spray-dryer and maltodextrin, in different concentrations (0; 5; 10%). Physical (water activity, solubility, salt content, and moisture), chemical (total phenolic concentration, antiradical activity, and organic and titratable acid concentration) and microbiological (total plate count and lactic acid bacteria) analyses were carried out. The major acids identified were oxalic, quinic, lactic, and acetic acid. Total phenol concentration was influenced by the concentration of maltodextrin used with higher values in the samples with no coating agent. The total viability of microorganisms and lactic acid bacteria (8.9·103 – 4.2·104 colony forming units (CFU)·g−1) did not reach the probiotic potential according to FAO and WHO. Salt concentration ranged from 8.9% to 14.3%, moisture content was 5.3 % to 7.03%, solubility in water — 81.74% to 82.8%. Horizontal spray drying with maltodextrin as a coating agent proved to be a suitable solution to obtain an innovative product — dehydrated fermented cabbage juice.

Published: March 2022

Honey can easily be adulterated with various cheaper sweeteners for higher commercial profits. Commonly used adulterants include high fructose maize syrup and refined cane sugar, which origin is C4 plants. Isotope ratio mass spectrometry (IRMS) can be used to determine the adulteration of honey with C4 plants. A significant δ13C value difference between honey and its protein provide valuable information of honey authenticity. The IRMS analysis of honey and its proteins and ultra high performance liquid chromatography – evoparative light scattering detection analysis for adulterated honey were performed to assess honey authenticity and origin. Principal component analysis of the obtained IRMS data was performed in order to determine discrimination between groups and for visualisation of observations. The results showed that isotope ratio values in combination with principal component analysis could be useful for determination of adulterant and discrimination of honey of different geographical origins. The chromatography results show ascending increase of the deliberately added sucrose, but do not fully recover the expected value.

Authors: Krumins Andris , Lebedeva Kristina , Tamane Antra , Millers Renars
Published: March 2022

Nowadays national and international directives have focused on improving energy efficiency in the building sector. According to them, energy consumption and emissions of buildings must be reduced. This can be achieved by balancing energy demand in buildings. In this context, this paper proposes a buildings’ energy demand balancing method using the building energy consumption simulation program IDA ICE and real measurements. A 3D model of the building was developed, energy consumption and indoor climate of the building was monitored throughout the year, the behaviour of the occupants (a survey was conducted) was analysed, dynamic change of the weather was studied and all data were integrated into IDA ICE simulation. In order to increase the energy efficiency of buildings, the possibilities of optimization of heat production equipment and heating devices, as well as inspecting and optimization of ventilation and cooling equipment were considered. By adjusting the parameters of the heating system of the researched object, the energy consumption of the auto centre decreased to 39.3 kWh/m2 per year. One of the most popular methods of balancing energy demand in recent years – the creation of smart grids – is also considered.
Complete Uterine Rupture: A Case Report
Authors: Uzel Kemine
Published: March 2022

Background: Uterine rupture during pregnancy is a considerable obstetric complication. The presence of a previous uterine scar is the most significant risk factor. Early clinical diagnosis is paramount to maternal and fetal survival. Case Report: A 36- year-old woman, gravida 2 para 2, presented with sudden acute abdominal pain at 38 weeks of gestation. The patient had a history of cesarean delivery one year ago. Ultrasound scans showed an empty endometrial cavity and fetus outside the uterus. Emergency laparotomy was performed, a live baby boy weighing 3.420 kg was delivered, and the uterine disruption was repaired. Conclusion: Increasing trends in the cesarean section may lead to a higher number of uterine ruptures. The survival of patients after uterine rupture depends on the time interval between rupture and intervention, and the availability of appropriate medical team and equipment. Health professionals caring for pregnant women should be alert for the symptoms and risk factors of uterine rupture.

Metastatic Triple-Positive Breast Cancer: A Case Report Not Response to Standard Protocols and Still Alive
Authors:   Specialist of Clinical Oncology and Nuclear Medicine, National Oncology Center, Aden, Yemen, SA Ahmed Noman
Published: March 2022

Breast cancer is the most common female cancer, the second most common cause of cancer death in women, and the main cause of death in women ages 40 to 49 years. Metastatic breast cancer is breast cancer that has spread beyond the breast and nearby lymph nodes to other parts of the body (most often the bones, lungs, liver or brain). The heterogenicity of Breast Cancer (BC) is determined by the status of human epidermal growth factor receptor 2 (HER2/neu), Estrogen Receptor (ER), and Progesterone Receptor (PR), TriplePositive BC (TPBC). Human Epidermal Growth Factor Receptor 2 (HER2) is overexpressed and/or amplified in approximately 20% of breast cancers, HER2 positivity is commonly associated with a more aggressive tumor phenotype and decreased overall survival and, moreover, with a reduced benefit from endocrine treatment. Our case is a Metastatic breast cancer with Triple positive, not response to standard protocols but she is still alive since seven years with minor complain until now.

We are reporting a case of 47 years old gentleman who was diagnosed with left lower alveolus carcinoma and later on he presented with epidermal inclusion cyst post oncological resection with nasolabial flap reconstruction. Compared to microsurgical free flaps, nasolabial flaps are simple, easy to learn, one staged procedure and provides good cosmetic results. It can be used bilaterally for coverage of both, intra-oral and extra-oral defects. It is highly vascular flap with blood supply from the facial, transverse facial, angular, infraorbital, infratrochlear artery and the free anastomosis between the terminal branches overlying the nasolabial skin. The important thing in harvesting this flap is to avoid implantation of epidermal tissue like hair follicles, sebaceous glands and sweat glands into the deep tissues. Inadequate de-epitheliaslisation results in formation of inclusion cyst during transposition of flap through trans-buccal tunnel into the oral cavity. Formation of inclusion epidermoid cyst is a rarely encountered phenomenon in head and neck cancers.

Since the outbreak of COVID-19 in January 2020, international online courses in universities in China have begun to develop on a large scale. This study explores the related influencing factors of teacher-student interaction on international student satisfaction with online courses in Chinese universities. It reveals which aspects of teacher-student interaction in online classes positively correlate with international students' satisfaction. This study is of a quantitative nature with four (independent variables (IVs) and one dependent variable (DV). The four IVs are the four dimensions of teacher-student interaction, namely interaction strength (IS), interaction time (IT), interaction content (IC), and interaction distance (ID). The DV is international student satisfaction (ISS) with online courses. This study was conducted in a university in Zhejiang Province, China. To answer the questionnaire, one hundred international students who were unable to enter China during COVID-19 were selected by stratified random sampling. The study used SPSS 21 to conduct descriptive and multiple linear regression analysis on the collected quantitative data. A total of 93 valid questionnaire data was collected. The analysis results showed that both IVs (IC & ID) have a positive correlation with the DV (ISS). Therefore, under the condition of limited equal resources, online teachers may give priority to the teacher-student interaction factors that have the greatest impact on the satisfaction of international students, carefully design teacher-student interaction activities, and maximise the satisfaction of international students.
Centralize or Decentralize? - The Question Currently Facing Schools in Qatar
Authors: Huda Al-Kubaisi
Published: March 2022

This study sought to explore the policy implementation issues related to the recent transition from an advanced EFNE decentralization to a strict re-centralization from the perspective of Qatar’s school principals. It focused on understanding the advantages and disadvantages of decentralization and re-centralization to identify the most appropriate model for schools that ensures the stability of the educational policy context. Gender and total service years were also considered in the study. The data was collected from 29 principals in government schools through questionnaires. Gender and total service years were also considered. Based on this, this study reveals there to be a level of satisfaction with the current re-centralization that together with the associated accountability increases the desire to emphasize the centralized structure that previously existed. Furthermore, in terms of answering the question on whether schools should be centralized or decentralized, Qatar's current situation differs significantly from the Western concept from which it was borrowed when it was initially created. Decentralization, in some cases, is not likely to be implemented because it is simply seen of as glamorous. Therefore, it is necessary to understand the internal forces, influences, and expectations of a specific context given its cultural norms and dispositions, and the desired educational outcomes when deciding its educational future. Without evidence-based endeavors supporting any policy change proposals, it is doubtful that a practical policy implementation would succeed.
