Published: August 2022

U radu autorka analizira ugovor o radu na određeno vreme u nemačkom pravu ukazujući na značaj koji taj ugovor ima u fleksibilnom radnopravnom okruženju. Ipak, zaključivanje ugovora o radu na određeno vreme se smatra izuzetkom, zbog čega se u nemačkom pravu izgrađuje princip objektivnog razloga koji opravdava njegovu upotrebu. To znači da se ugovor o radu na određeno vreme smatra poželjnim instrumentom za zasnivanje radnog odnosa samo ako su za to ispunjeni zakonom predviđeni uslovi. Otuda se u radu navode dopušteni slučajevi, ograničenja u korišćenju ugovora o radu kroz limitiranje broja sukcesivnih ugovora i maksimalne dužine ukupnog trajanja ugovora. U radu se prikazuje i „legislativna istorija” ugovora o radu na određeno vreme, nakon njegovog pojmovnog određenja. Na samom kraju se ukazuje na zabranu diskriminacije atipičnih zaposlenih koji ne smeju uživati manje prava u poređenju sa drugim zaposlenima kod poslodavca, posebno onim sa standardnim ugovorom o radu.
Blocked or Broken? Automatically Detecting When Privacy Interventions Break Websites
Authors: Smith Michael , Snyder Peter , Haller Moritz , Livshits Benjamin , Stefan Deian , Haddadi Hamed
Published: August 2022

A core problem in the development and maintenance of crowdsourced filter lists is that their maintainers cannot confidently predict whether (and where) a new filter list rule will break websites. The enormity of the Web prevents filter list authors from broadly understanding the compatibility impact of a new blocking rule before shipping it to millions of users. This severely limits the benefits of filter-list-based content blocking: filter lists are both overly conservative (i.e. rules are tailored narrowly to reduce the risk of breaking things) and error-prone (i.e. blocking tools still break large numbers of sites). To scale to the size and scope of the Web, filter list authors need something better than the current status quo of user reports and manual review, to stop breakage before it has a chance to make it to end users. In this work, we design and implement the first automated system for predicting when a filter list rule breaks a website. We build a classifier, trained on a dataset generated by a combination of compatibility data extracted from the EasyList filter project and novel browser instrumentation, and find that our classifier is accurate to practical levels (AUC 0.88). Our open-source system requires no human interaction when assessing the compatibility risk of a proposed privacy intervention. We also present the 40 page behaviors that most predict breakage in observed websites.
gOTzilla: Efficient Disjunctive Zero-Knowledge Proofs from MPC in the Head, with Application to Proofs of Assets in Cryptocurrencies
Authors: Baldimtsi Foteini , Chatzigiannis Panagiotis , Gordon S. Dov , Le Phi Hung , McVicker Daniel
Published: August 2022

We present gOTzilla, a protocol for interactive zero-knowledge proofs for very large disjunctive statements of the following format: given publicly known circuit C, and set of values Y = {y1 , . . . , yn }, prove knowledge of a witness x such that C(x) = y1 ∨ C(x) = y2 ∨ · · · ∨ C(x) = yn . These type of statements are extremely important for the proof of assets (PoA) problem in cryptocurrencies where a prover wants to prove the knowledge of a secret key sk that associates with the hash of a public key H(pk) posted on the ledger. We note that the size of n in popular cryptocurrencies, such as Bitcoin, is estimated to 80 million. For the construction of gOTzilla, we start by observing that if we restructure the proof statement to an equivalent of proving knowledge of (x, y) such that (C(x) = y) ∧ (y = y1 ∨ · · · ∨ y = yn )), then we can reduce the disjunction of equalities to 1-out-of-N oblivious transfer (OT). Our overall protocol is based on the MPC in the head (MPCitH) paradigm. We additionally provide a concrete, efficient extension of our protocol for the case where C combines algebraic and non-algebraic statements (which is the case in the PoA application). We achieve an asymptotic communication cost of O(log n) plus the proof size of the underlying MPCitH protocol. While related work has similar asymptotic complexity, our approach results in concrete performance improvements. We implement our protocol and provide benchmarks. Concretely, for a set of size 1 million entries, the total run-time of our protocol is 14.89 seconds using 48 threads, with 6.18 MB total communication, which is about 4x faster compared to the state of the art when considering a disjunctive statement with algebraic and non-algebraic elements.
Zswap: zk-SNARK Based Non-Interactive Multi-Asset Swaps
Authors: Engelmann Felix , Kerber Thomas , Kohlweiss Markulf , Volkhov Mikhail
Published: August 2022

Privacy-oriented cryptocurrencies, like Zcash or Monero, provide fair transaction anonymity and confidentiality, but lack important features compared to fully public systems, like Ethereum. Specifically, supporting assets of multiple types and providing a mechanism to atomically exchange them, which is critical for e.g. decentralized finance (DeFi), is challenging in the private setting. By combining insights and security properties from Zcash and SwapCT (PETS 21, an atomic swap system for Monero), we present a simple zk-SNARKs based transaction scheme, called Zswap, which is carefully malleable to allow the merging of transactions, while preserving anonymity. Our protocol enables multiple assets and atomic exchanges by making use of sparse homomorphic commitments with aggregated open randomness, together with Zcash friendly simulation-extractable non-interactive zero-knowledge (NIZK) proofs. This results in a provably secure privacypreserving transaction protocol, with efficient swaps, and overall performance close to that of existing deployed private cryptocurrencies. It is similar to Zcash Sapling and benefits from existing code-bases and implementation expertise.
Formalizing and Estimating Distribution Inference Risks
Authors: Suri Anshuman , Evans David
Published: August 2022

Distribution inference, sometimes called property inference, infers statistical properties about a training set from access to a model trained on that data. Distribution inference attacks can pose serious risks when models are trained on private data, but are difficult to distinguish from the intrinsic purpose of statistical machine learning—namely, to produce models that capture statistical properties about a distribution. Motivated by Yeom et al.’s membership inference framework, we propose a formal definition of distribution inference attacks general enough to describe a broad class of attacks distinguishing between possible training distributions. We show how our definition captures previous ratio-based inference attacks as well as new kinds of attack including revealing the average node degree or clustering coefficient of training graphs. To understand distribution inference risks, we introduce a metric that quantifies observed leakage by relating it to the leakage that would occur if samples from the training distribution were provided directly to the adversary. We report on a series of experiments across a range of different distributions using both novel black-box attacks and improved versions of the state-of-the-art white-box attacks. Our results show that inexpensive attacks are often as effective as expensive meta-classifier attacks, and that there are surprising asymmetries in the effectiveness of attacks.

Published: August 2022

Violence in the home is a major scourge in the society that needs unique attention to combat. There is a general saying that a happy mind gives strength to the whole body which means a happy woman makes a happy home, while a happy home makes a happy society. To this end, violence as a negative condition to the well-being of women is purely devastating to their happiness especially when it occurs within the home. This paper therefore explored survey design method technique in finding out the socio-cultural factors associated with home violence as experienced by women and its effects in Oye Ekiti, a town in Ekiti State of Nigeria. In a convenient sampling technique, data were collected from 200 married women who responded to questionnaire.   . Hypotheses were tested using chi-square. Results showed that factors such as level of education, religion belief and income were mostly among others not associated with violence in the home, which means there are more underlying factors to look out for. It was therefore recommended that government should incite stricter laws in addressing home violence cases Family courts should also be put in place early warning systems to become aware   of the consequences of ill-treatment of women at home. Also, religious organization should be more proactive in the teaching of morals towards curbing home violence.

Published: August 2022

COVID-19 Pandemic has forced the Commission on Higher Education (CHED) to mandate Higher Education Institutions (HEIs) in the Philippines the paradigm shift of teaching-learning to distance learning called Flexible Learning Modality (FLM). Dealing with this, to determine the lived experiences of Bulacan Agricultural State College (BASC) students in the new normal and its implication for instructional effectiveness, this Grounded theory study aimed to describe the students' perception on the use of FLM, to determine the challenges and opportunities that students face in the new normal to determine ways to improve the teaching-learning process through the use of FLM. With the purposive sampling as the technique for acquiring the number of informants, and constructivist design of coding in generating assumptions, themes and core categories, a total of five emerging themes were extracted, namely (1) Work-study balance; (2) engaging, interactive and convenient; (3) less engaging, less effective and less interactive; (4) internet-related issues; and (5) leniency for sanity were the emerging themes extracted from the responses. The researchers developed a theoretical model from the responses of ten student-informants. The generated model describes the challenges and opportunities of students in the use of FLM that are influenced by the teacher factor, connectivity factor, and time factor. These challenges and opportunities led to several implications which will serve as grounds for the instructional effectiveness of FLM in tertiary education.

Transiting from Manual Voting to Electronic Voting System for Enduring Democratic Governance in Nigeria: The Imperative for Digital Remedy
Authors: Paul Chima
Published: August 2022

The paper investigates the enormity of hitches tied to transiting from manual-based electoral systems to the electronic voting system and determine whether hurdles with the electronic voting system could be sufficient enough to prevent Nigeria from adopting it to enhance her democratic governance in the 21st century. This enquiry was prompted on the ground that there are mixed reactions from different individuals, scholars and societies that the Nigerian state is not ripe for electronic voting and as such may not be able to sustain it if it eventually steps into full adoption of electronic voting system. Therefore, they argue that the status quo ante should be maintained. However, available documentary evidence and cases drawn from other climes where electronic voting has been practised across the globe show that the cost-saving potential of electronic voting is limitless, it eliminates electoral frauds, votes are completed and submitted online, thereby saving ample time, it restricts movement, which eventually eliminates voter apathy caused by fear of violence, etc. On the other hand, most scholars are overwhelmingly inclined to the opinion that the electronic voting system is capable of exacerbating the digital divide as it is lopsided in affecting the turnout of certain groups of citizens. This implies that e-voting will favour only well-educated and wealthy people to the detriment of the downtrodden in the society. The paper however concludes that the Achilles’ heel of transiting from manual to the electronic voting system identified are tangential and could be surmounted with the passage of time through sensitization and awareness creation.
Analytical Framework of Cloud Homomorphic Encryption / Cryptographic Logic Obfuscation for Cyber Health Hygiene
Authors: Thursday Ehis Akhigbe-mudu
Published: August 2022

Hacking and the resulting disaster have become so dangerous that developers and organizations are taking extra precautions to reduce their incidence and impact. A drift is any gap between the code and the cloud. Ad hoc adjustments can, of course, result in environment instability, deployment challenges, unpredictably high costs, and security or compliance gaps. The risk of configuration drift becoming a permanent fixture is one of the most important considerations on this study. One such strategic strategy to mitigate these behaviors and render it unavailable to tracking, interpretation, and use by hackers is logic obfuscation. This study presents two strategies for combating piracy and overbuilding attacks. First, the proposed algorithms, then the logic obfuscation develop to hide the functionality and implementation of a design by inserting gates onto the original design. The attackers can use circuit extraction from the gate-level netlist but they won’t be able to deduce the obfuscated logic functions. As a result, the proposed obfuscation technique in this brief not only resists image processing but also incurs low area and power overhead.

In this paper, we will analyze the behaviors of enterprises and customers, and help them make best decision for geting optimal profits. Today small and medium enterprises play an important role in our economy. When enterprises are small or medium, they need to find an effective way to reach decisions. In the paper, we will employ game theory to analyze it. Also, as relationship of the manufacturer and retailers can be taken as Stackelberg behaviors, we will build models based on Stackelberg behaviors. In order to make optimal decisions for the chain members, we use crisp numbers and fuzzy numbers in expressing the market demand. After that, we will analyze which is more accurate to the real situation and which is better to gain more profit for the members on the supply chain. Finally, we can get conclusions for the members on the supply chain. We clarify the advantage and disadvantage about this model of supply chain taken by small and medium enterprises.
A HYBRID FUZZY C-MEDOIDS CLUSTERING USING THE WHALE OPTIMIZATION ALGORITHM
Authors: Nguyen Anh Cuong
Published: August 2022

Although the fuzzy c-means algorithm (FCM) has been widely used in many fields, they are sensitive to noise and outliers. Recently, the Fuzzy C-Medoids (FCMdd) algorithm has been shown to be more effective in dealing with noise data. The difference between FCM and FCMdd is the formation mechanism of clusters. At the same time, FCM builds clusters based on membership function and samples in the cluster. FCMdd selects some of the existing actual samples as cluster medoids. This results in FCMdd being able to handle noise better than FCM. This paper presents a hybrid approach of the whale optimization algorithm WOA with FCMdd (FWCMdd) to optimize the clustering process. This hybridization prevents FWCMdd from falling into the local trap and rapidly converging. This solution has been compared with the Fuzzy k-Medoids (FKM) algorithm and the primitive FCMdd. The results indicate that the proposed method is better than most of the evaluation indicators.

Published: August 2022

The paper presents the issue of improving the efficiency of the radar target recognition by flexibly extending the observation time, giving results of evaluating the quality metrics of “the multi-step recognition algorithm with the ability to meet the reliability of decisions” in the case of recognizing radar targets on Gaussian noise. In the paper, we use the simulation method to determine the probability matrix of conditional true/false recognition and the statistical properties of the required number of observation cycles. The simulation results show that the multi-step algorithm improves the probability of true recognition and allows to meet the reliability of the decisions with the average number of required observation cycles significantly smaller than that in the case of using the conventional one-step algorithm.
A novel digital transceiver module structure for multi-functional active phased array systems
Authors: Pham Cao Dai
Published: August 2022

This paper proposes a transceiver (T/R) module structure for the multi-functional active phased array (APA) systems (including radar and wireless communication systems). The proposed structure uses a full digital interface and applies a GaN supply-modulated power amplifier (SMPA) to improve the power efficiency. In particular, the paper proposes a solution that combines the direct digital synthesis (DDS) with IQ modulation to perform flexibly the functions of phase shifting and amplitude level controlling of the transmitted signals with high resolution for antenna beamforming and scanning. The proposed solution not only eliminates RF attenuator and phase shifter that are commonly used in antenna beamforming but also flexibly configures system functions. The experimental results of designing and manufacturing DDS and IQ modulation parts demonstrate the ability of the proposed structure to generate several common signal types used in radar and communication systems as well as verifies the ability to control the phase and the amplitude level of the transmitted signal.
Pruning-based intrusion detection for maximizing the traffic management in Internet of Things
Authors: Dao Thi-Nga
Published: August 2022

This work considers the problem of maximizing the number of packets to be classified by the network security system in programmable switches in Internet of Things. With the purpose of developing a lightweight security method for programming switches with limited computing resource, we present a neural-network-based intrusion detection model that combines with a neuron pruning method to achieve low model complexity without significant sacrifice in accuracy. Then, we formulate an integer linear programming (ILP) problem that maximizes the amount of monitored traffic by all switches under requirements of classification accuracy and computing resources. The optimization problem is considered in two cases: using and not using the neuron pruning (NP)-based models to show the benefits of the proposed lightweight architecture. The evaluation results show that NP-based models allow switches to manage more data traffic while satisfying given requirements of accuracy and computing resources.
ANALYSIS OF THE STRESS AND DEFORMATION FOR THE ARTILLERY BREECH BLOCK BEFORE AND AFTER REPAIR
Authors: Nguyen Van Hung
Published: August 2022

The mechanical structure of the breech block after repairing is different from the original breech block. It is assembly parts of the new front-end face, the original breech block, and the connecting screws. So analyzing the stress and deformation of the breech block is an important issue in the repair process for the breech block. The paper is focused on analyzing the stress and deformation of the breech block before and after repair using the finite element method (FEM) approach. Besides, the results of the FEM are compared with the analytical method approach. The comparison between the results of the analytical method and FEM results shows a very good agreement (before repair, the difference in maximal stress between the two methods is 2.12%). The study object of this paper is the wedge-type breechblock.

Published: August 2022

Sorting coffee beans is a crucial stage to achieve high quality and raise the value for the product. This work usually takes a short time to conduct with a large number of coffee beans, while sorting by hand is hard to respond to. And in some cases, appearances of bad coffee beans are nearly similar to good ones, this is hard to distinguish by eyes as sorting in bulk. So an efficient algorithm used particular standards to sort coffee is necessary. From existed issues, this paper presents an efficient approach used as a computer vision system to sort coffee beans based on the criteria about shape and color of the product. Geometric properties and a linear graph are used in this paper to analyze the features of the product. Coffee beans are categorized into two major groups: bad beans and good beans, corresponding to quality standards about specific color and shape. Our proposed method detects and covers the majority of types of bad beans, and get high at both the accuracy metric and F1-score metric with fast speed in sorting.
PERFORMANCE IMPROVEMENT OF NONLINEARITY COMPENSATION USING OPTICAL PHASE CONJUGATION FOR METRO DWDM SYSTEMS WITH OPTICAL ADD DROP MULTIPLEXERS
Authors: Nguyen Duc Binh
Published: August 2022

Wavelength Division Multiplexing (WDM) has been widely applied in optical adddrop multiplexing (OADM) fiber metro systems with an increasing number of wavelength channels and sufficiently narrow channel spacing. The problem that appears here is the signal distortion produced by dispersion and nonlinearity effects. To cope with these effects, many compensation solutions have been introduced, such as digital compensation (DC) solutions on technology of digital signal processing (DSP) or optical phase conjugation (OPC) on alloptical domain. In fact, research on using OPC to compensate for dispersion and nonlinearity in metro transmission systems are incomplete, especially with large number multiplexing systems. In this paper, we propose to use OPC for dispersion and nonlinear compensation in DWDM metro systems. Specifically, we focus on two common types of modulation signals: QPSK and 16-QAM; operations in 16- and 32-channel dense WDM system. The simulation results show that the system quality increases significantly when using OPC to compensate for dispersion and nonlinearity, e.g. when transmitting 16-QAM signals in a 32-channel system passing through 20 add/drop nodes, the gain of Q factor is greater than 2 dB.

High blood pressure or hypertension has been called the "silent killer", because it often has no warning signs or symptoms, and many people do not even know they have it. Over time, the constant pressure overload causes accumulating damage that eventually becomes more than your circulatory system can handle, often leading to serious health problems. Method: The present study is conducted to observe its prevalence in the city Faisalabad and its prescription trends by using retrospective method. The objective of this was to evaluate trends in prescription drug use among population living in the Faisalabad. Several hospitals in the area were visited for this article which includes DHQ, Allied Hospital, FIC and National hospitals. Results: The study explores which age group people, which gender is more prone towards this ailment. How lifestyle, diet and other factors affect blood pressure Moreover, it tells us how other diseases are interrelated with hypertension. It also provides information about the prescription trends of anti-hypertensive drugs. It elaborate that almost 47% male and 53% female are affected by this disease. Conclusion: Major cause of hypertension in female patients is angina and depression. Moreover, our data suggested that most of the outpatients with hypertension receive monotherapy and most frequently used class of drugs is the CCBs and ARBs. Studies showed that hypertension mostly coexist with heart diseases and other co-morbidities like diabetes. Any how the incidence of hypertension is dependent upon several factors like age, ethnicity, diet, and life style, environmental and physiological factors.

Objective: The objective of this study was to formulate and optimize a mouth dissolving formulation of levosulpiride. Method: Levosulpiride mouth dissolving tablet having D2-dopamine receptor antagonistic activity were made by direct compression using microcrystalline cellulose, mannitol, povidone and a disintegrant sodium starch glycolate. Thus, formulating levosulpiride into amouth dissolving dosage form would provide fast relief. Results: The tablets were evaluated for weight variation, drug content, content uniformity, hardness, friability, in-vitro disintegration time and in-vitro drug release. The results show that the presence of a superdisintegrant and mannitol is desirable for orodispersion. Conclusion: Formulations satisfied the limits of orodispersion with a dispersion time of less than 60 sec, optimized drug released within 30 min and the formulations followed first order linear kinetics. So, it is feasible to formulate mouth dissolving tablets of levosulpiride with acceptable disintegration time, rapid drug release and good hardness as an alternative to conventional tablet.

Objectives: The present investigation is concerned with formulation and evaluation of mucoadhesive buccal tablets containing antidiabetic drug, glimepiride, to circumvent the first pass effect and to improve its bioavailability with reduction in dosing frequency and dose related side effects. Methods: The tablets were prepared by direct compression method. The tablets were tested for weight variation, hardness, surface pH, drug content uniformity, percentage swelling index, bio adhesive strength, exvivo residence time in-vitro drug dissolution study, in-vitro drug release kinetic study, ex-vivo permeation study and stability study. Results: FTIR studies showed no evidence on interactions between drug, polymers, and excipients. The surface pH, bio adhesive strength, ex-vivo residence timeand swelling index of formulation was found to be 6.80±0.02, 36.3±0.04g, 325min and 289.8±0.52%, respectively. The formulation containing 4 mg of glimepiride exhibited 6 h sustained drug release i.e. 93.98±0.8% with desired therapeutic concentration. The drug permeation from the formulation was slow and steady and 3.56 mg of glimepiride could permeate through sheep buccal membrane with a flux of 0.27 mg hr-1 cm-2 . The in-vitro release kinetics studies reveal that all formulations fits well with zero order kinetics and followed non-Fickian diffusion mechanism. Conclusion: Hence, it was concluded that the best formulation was suitable for all the evaluation parameters and can be permeated through human buccal mucosa.
