Exploratory Research on Comparing Breast Pumps: Using Data to Objectively Evaluate Pump Qualities
Authors: Tolman Allison 
Published: November 2023

Objective:By understanding the terminology, functionality, and metrics that matter in breast pumps, both lactation professionals and pump users will be able to better identify, compare, and effectively use breast pumps for efficient milk removal.Methods:A device was created (breast pump vacuum monitoring system) that monitors and logs pressure data with respect to time and generates a pressure/time graph for a visual representation of breast pump performance in addition to providing max/min pressures, average pressure, and periodic cycle time estimations.Results:This exploratory testing showed that breast pumps varied widely in their abilities to maintain effective vacuum suction during simultaneous pumping. Maximum suction data points often refer to single-sided pumping. Cycles per minute (CPM) vary widely as well across breast pumps but can be categorized into two main ranges of 10–70 CPM (expression) and 60–120 CPM (stimulation). We found four major categories of suction patterns in our testing: standard pull and release, microvibration, constant suction, and combination patterns. A combination of these metrics makes up an individual pump’s unique programming.Conclusions:Breast pumps are a complex combination of vacuum strength, cycle speeds, and suction pattern, all of which must be optimized appropriately to function effectively. The lack of available important metrics on individual breast pumps, along with an incomplete understanding of the data presented in popular pump marketing, provides a difficult scenario for evaluating and comparing breast pumps.

Published: November 2023

Objective:Expressing (pumping) human milk is a widespread practice among breastfeeding parents in the United States. However, parents report receiving conflicting information from healthcare providers about pumping. Therefore, the purpose of this qualitative descriptive study was to explore lactation care providers’ (LCPs) training, knowledge, and information needs related to pumping.Methods:Fifteen LCPs enrolled and participated in semistructured interviews that were analyzed by the authors to extract themes.Results:The authors identified three main themes:Gaining Knowledge,Confidence in Basic Principles, andFlange and Pump Uncertainties. These participants felt that they were taught the basic principles about pumping initially but did not feel they were provided enough initial formal training on hands-on skills related to pumping, especially flange fitting.Conclusion:More research and training are needed on flange fitting. New LCPs in the United States may need to seek additional training and mentorship to become competent in pumping support.

Bencana geologi berupa semburan gas dangkal telah terjadi beberapa kali di Balikpapan akibat aktivitas peengeboran yang tinggi. Sebaran titik semburan gas menjadi pembahasan menarik dikarenakan sebagian besar terjadi di daerah pesisir Kota Balikpapan. Belum diketahui dengan jelas penyebab kantung-kantung gas dangkal tersebut tersebar di daerah pesisir Balikpapan. Kajian mengenai kebencanaan ini juga masih sangat minim. Oleh karena itu, penelitian ini bertujuan untuk mengidentifikasi zona kerawanan gas dangkal di wilayah Baikpapan sebagai upaya mitigasi bencana dan studi pendahuluan mengenai bencana geologi ini. Penelitian ini dilakukan dengan memadukan data sekunder dan primer. Data sekunder merupakan laporan mengenai riwayat semburan gas yang telah terjadi. Laporan tersebut digunakan sebagai penentu awal daerah kerawanan gas dangkal. Data primer merupakan data hasil penyelidikan geologi dan geofisika. Penyelidikan geologi dan geofisika dilakukan di sekitar daerah pusat semburan gas dangkal. Penyelidikan geologi dilakukan dengan mengamati struktur, litologi, serta jurus dan kemiringan. Luarannya berupa peta geologi. Di sisi lain, penyelidikan geofisika dilakukan dengan pengukuran geolistrik untuk memperoleh distribusi resistivitas bawah permukaan. Zona rawan gas dangkal diduga berada pada daerah yang memiliki struktur antiklin yang berfungsi sebagai perangkap gas. Keberadaan gas dangkal dikonfirmasi oleh anomali resistivitas tinggi bawah permukaan. Dari penelitian ini diidentifikasi bahwa zona aman gas dangkal yang tersebar di sebelah utara daerah penelitian. Sedangkan daerah selatan penelitian didominasi oleh zona rawan gas dangkal.

Published: November 2023

One of the priority tasks of the energy industry is to ensure the reliable and safe operation of steam turbine units of thermal power plants and nuclear power plants. Given the difficult situation in the country, it is impossible to replace outdated equipment that has exhausted its design resource with new ones. As is known, the safety factor of the material taken into account during the design of steam turbine equipment was very approximate. At that time, there were no data on the operation of power equipment, which would have already worked for 200-220 thousand hours. in difficult operating conditions. The situation has changed now. There are power installations that have exhausted or are close to exhausting their design resource. By conducting experimental studies with metal samples of this equipment, it is possible to significantly clarify the physical and mechanical properties of steels and their damage due to operation. Therefore, the problem of extending the resource is becoming increasingly important. Computer modeling has greatly simplified the task of calculating the resource of the equipment. However, such a complex object as a steam turbine requires significant computing resources, and the calculation of equations in all finite element nodes is quite time-consuming. It is necessary to look for ways to rationalize calculation mathematical models. At the same time, the accuracy of the calculation should remain at a satisfactory level. In this work, were created simplified geometric models of the rotor of the LPC turbine unit К-1000-60/3000. The option is considered of replacing the working blades with equivalent distributed masses and toroidal rings. Verification of the obtained models based on critical rotation frequencies confirmed the possibility of replacing the working blades with distributed masses. On the other hand, the presence of toroidal rings of large radii leads to a significant reduction of critical frequencies in comparison with normalized values.
Боротьба проти безробіття: історичний досвід волині періоду НЕП

Published: November 2023

У статті комплексно проаналізовано підходи радянських органів влади на Волині для боротьби з безробіттям під час періоду Нової економічної політики (НЕП). Виявлено, що встановлення надійного контролю над показниками ринку праці було складним завданням; адміністративно-командні процедури переважали в зусиллях із подолання безробіття, а бюрократична спрямованість на полегшення безперешкодної роботи бірж праці була недостатньою. Проте ініціатива режиму щодо надання фінансової допомоги безробітним щомісяця визнавалася позитивним кроком, що дало змогу спрямувати значні кошти на вирішення дотичних проблем і використання громадських робіт для зменшення кількості безробітних. Попри все, дискусія щодо безробіття серед жінок та підлітків на Волині залишається малодослідженою і потребує глибшого вивчення.

Detection of Unauthorized Actions in Networks Using Wavelet Analysis
Authors: Hrynchenko Pavlo 
Published: November 2023

Signal processing techniques are used to analyze and detect network anomalies because of their ability to detect new and unknown intrusions. The paper proposes a method of modeling network signals for the detection of network anomalies, which combines wavelet approximation and the theory of system identification. To characterize the behavior of network traffic, fifteen functions are provided, which are used as input signals within the system. At the same time, it is assumed that security violations within the network can be detected by checking abnormal patterns of system functioning according to audit data.
Despite the fact that machine learning methods have achieved significant results in detecting network anomalies, they still face the difficulty of using the implemented algorithms, in the presence of differences in the behavior of the training data and test data, which in turn leads to inefficient performance of the algorithms. This effect is exacerbated by the limitation of algorithms to detect previously unknown types of attacks due to the large number of false positives.
The paper develops a new method of modeling network signals for detecting anomalies in networks using wavelet analysis. In particular, the general architecture of the approach consists of three components: feature analysis, modeling of normal network traffic based on wavelet approximation and prediction using ARX model, intrusion or non-intrusion decision making
The result is evaluated using the DARPA intrusion detection dataset, which performs a comprehensive analysis of the intrusions in the dataset. Evaluation results show that this approach provides a high level of detection of both instances and types of attacks.
On Inverse Protocols of Post Quantum Cryptography Based on Pairs of Noncommutative Multivariate Platforms Used in Tandem
Authors: Ustymenko Vasyl 
Published: November 2023

Non-commutative cryptography studies cryptographic primitives and systems which are based on algebraic structures like groups, semigroups and noncommutative rings. We continue to investigate inverse protocols of Non-commutative cryptography defined in terms of subsemigroups of Affine Cremona Semigroups over finite fields or arithmetic rings Zm and homomorphic images of these semigroups as possible instruments of Post Quantum Cryptography. This approach allows to construct cryptosystem which are not public keys, when protocol finish correspondents have mutually inverse transformations on affine space Kn or variety (K*)n where K is the field or arithmetic ring.
The security of such inverse protocol rests on the complexity of word problem to decompose element of Affine Cremona Semigroup given in its standard form into composition of given generators. We discuss the idea of usage combinations of two cryptosystems with cipherspaces(K*)n and Kn to form a new cryptosystem with the plainspace(K*)n, ciphertextKn and nonbijective highly nonlinear encryption map.
