Published: September 2023

Использование беспилотных транспортных средств, особенно беспилотных авиационных систем, для решения широкого спектра задач коммерческих и государственных организаций в последние годы интенсифицировалось. Преднамеренное или непреднамеренное искажение данных БАС потенциально может привести к опасным инцидентам техногенного характера с угрозой жизни и здоровью людей. Соответственно, возрастает потребность в обеспечении кибербезопасности таких систем в целом и защиты данных, необходимых для их корректного функционирования, в частности. Традиционные методы обеспечения безопасности не всегда подходят для сенсоров и аппаратного обеспечения систем беспилотного транспорта из-за целого ряда ограничений и особенностей функционирования. Настоящая статья открывает цикл публикаций, посвященных информационной безопасности БАС. Целью настоящей статьи является анализ векторов атак на сенсоры и их каналы, а также изучение аппаратного обеспечения БАС. Проведен обзор методов защиты от подобных атак. В работе применялись методы контент-анализа и эксперименты с коммерческими беспилотными авиационными системами, доступными для гражданских пользователей. В результате был разработан систематизированный перечень атак на сенсоры и аппаратное обеспечение, оформленное в виде таблиц в данной статье.
The use of unmanned vehicles, especially unmanned aerial systems (UAS) for a wide range of tasks of commercial and government organizations has intensified in recent years. Intentional or unintentional distortion of UAS data can potentially lead to dangerous man-made incidents with a threat to human life and health. Accordingly, there is an increasing need for ensuring the cybersecurity of such systems in general and protecting the data necessary for their correct functioning, in particular. Traditional security methods are not always suitable for sensors and hardware of unmanned vehicle systems due to a number of limitations and features of operation. With this article, the authors open a series of articles on UAS information security. The purpose of this article is to analyse attack vectors on sensors and their channels, as well as UAS hardware. In addition, the authors reviewed methods of protection against such attacks. In their work, the authors applied content analysis methods and experiments with real commercial unmanned aerial systems available to civilian users. As a result, the authors have developed a systematic list of attacks on sensors and hardware, presented in the form of tables in this article.

Published: September 2023

Рассмотрены два подхода к организации функционирования и обслуживания технической системы, отличающихся порядком использования запасных типовых элементов замены. Показано, что задача определения необходимого их количества для локальной вычислительной сети не может быть сведена к решению классических задач теории управления запасами. Разработаны математические модели функционирования и технического обслуживания системы, позволяющие определить необходимое количество запасных типовых элементов замены.
The article revises two operation and maintenance organization approaches that have different spare elements use order. It is showed that the task of defining the required spare element quantity for local network cannot be derived from classic theory of stock management. The article describes developed math models for operation and maintenance that allow to define the required spare elements quantity.
An EPQ Model for Delayed Deteriorating Items with Reliability Consideration, Quadratic Demand and Shortages
Authors: Sani Dari 
Published: September 2023

In this paper, an EPQ model for items that exhibit delay in deterioration is developed. It is assumed that there is no demand and no deterioration during production buildup period. Demand starts immediately after production but no deterioration. Then a period of deterioration sets in until the stock finishes. It is also supposed that the cost of a unit product is inversely related to the rate of demand and directly related to the process reliability (as assumed by Tripathy et al. (2015) and modified by Dari and Sani (2015)). The demand before deterioration sets in is quadratic time dependent while demand after deterioration sets in is a constant. Shortages are allowed and partially backordered. A numerical model is given to compare the simulation model and the statistical analysis conducted on the model to see the effect of measurement changes in other system parameters.
Fogo e manejo da terra na Amazônia: por um novo arcabouço teórico-metodológico
Authors: Chermont Larissa 
Published: September 2023

O presente artigo tem por objetivo principal apresentar um arcabouço teórico-metodológico alternativo que possibilite a análise do comportamento do camponês na Amazônia brasileira no que diz respeito à adoção do fogo como técnica de manejo da terra. A partir de uma ‘reconstrução teórico-metodológica’, pretende-se: (i) demonstrar a inadequação das formulações amplamente utilizadas (mainstream) de modelos de previsão do comportamento do agricultor familiar provindas da vertente Neoclássica da teoria econômica, fundamentadas nas noções de racionalidade e maximização de utilidade; (ii) apresentar um modelo conceitual alternativo do comportamento do camponês quanto à adoção do fogo como técnica de manejo da terra, demonstrado preliminarmente por uma tipologia do camponês do Corredor da BR-163; (iii) estabelecer ‘diálogos transversais’ queperpassem as diversas disciplinas nas quais o fenômeno em foco se manifesta. O campo da produção camponesa na Amazônia brasileira servirá como empiria para a identificação da dinâmica social e análise do comportamento do camponês como agente desse subcampo econômico. Em suma, este trabalho pretende qualificar o problema do uso do fogo e suas consequências na vida do homem rural amazônico, de forma a contemplar os diversos aspectos da ‘realidade complexa’ em que ele se insere e preencher a lacuna existente na literatura sobre o tema
Life Quality in People Serving Prison Sentences in Romanian Penitentiary Institutions. Premises for Future Socio-Educational Programs
Authors: Mindrescu Veronica 
Published: September 2023

The present paper aims to bring forward the impact that the quality of life has on the detainees of penitentiary institutions and the way they navigate their prison living throughout their sentence. As the parameters have shown herein, the quality of life on prison detainees differs based on their assessments of life within the confined spaces of the penitentiary, including their relationships with other detainees, the support activities they are involved in and whether they have definitely been convicted or they have been in their pretrial detention period. This prerequisite has been quite important in the evaluation of the quality of life for detainees since based on these convictions, if permanent or temporary, and through the help of the survey as method of investigation, one has been able to outline the different needs, activities, opportunities and standard of living per se of the ones placed under the confinement of the law. This assessment has put forward also the relationships that the detainees have with the participation in the socio-educational programs and medical services offered within and with the participation in the sports activities carried out, while highlighting their understanding and judgment of how they are being treated inside, thus the right to humanity and decency.
Using Social Media Resources to Build Young People's Professional Futures
Authors: Drăghici Elisaveta 
Published: September 2023

Young people are exploring alternatives, informing themselves and exchanging impressions among themselves, in order to finalise their career choices. An active means of information is using social media resources, especially by joining social networking groups to discuss issues related to learning, choosing universities, helping by providing study materials or sharing learning practices for baccalaureate or college admission, etc.
I will present, as a case study, an active Facebook group. The investigation will aim to explore a set of dimensions such as: young people's topics of interest, career visions, expectations after graduation from university (where they can work after graduation), forms of support among young people on learning and preparation for the transition from high school to university, etc. We are witnessing a pattern of informal education taking place within generations of young people at the stage of choosing a professional field.
The approach will be both qualitative and the applied research method will be case study. The novelty of the topic is to show that young people use social media to inform themselves and crystallise career options, thus using technological resources constructively. Time spent on the internet is valued for life planning and not just for entertainment.

Nomorhamphus sp. is a freshwater fish that has been traded as an ornamental fish. This fish is unique as an endemic species with a halfbeak-like jaw and orange color on the caudal fin. However, this fish culture information needs a further information. Based on this condition, it is necessary to conduct a study as a basis for ornamental fish breeding and growing-out activities through domestication. A crucial problem in this fish is larval rearing, which can be observed through ontogeny studies. The study was conducted on the newly-born larval behavior, morphological development, andropodium development, growth, and survival rate at the early stages, namely larvae to juvenile. The results showed that the newly-born larvae of Nomorhamphus sp. Lindu had a total length of 1.6-1.8 cm. Larvae could swim four hours 22 minutes after birth and feed artemia nauplii with surface feeding type. The initial juvenile stage occurred 25 days of post-birth period with a total length of 2.0-2.2 cm. The water condition of the rearing during the study could support the larval transformation to juvenile. This study is the first report related to the aquaculture success of the early life stage of Nomorhamphus sp. Lindu at the domestication stage.

A Discrete New Generalized Two Parameter Lindley Distribution: Properties, Estimation and Applications
Authors: Salem Manal M. , Ismail Moshira A. 
Published: September 2023

In this paper, a discrete new generalized two parameter Lindley distribution is proposed. Discrete Lindley and Geometric distributions are sub-models of the proposed distribution. Its probability mass function exhibits different shapes including decreasing, unimodal and decreasing-increasing-decreasing. Our proposed distribution has only two-parameters and its hazard rate function can accommodate increasing, constant, decreasing and bathtub shapes. Moreover, this distribution can describe equi and over dispersed data. Several distributional properties are obtained and several reliability characteristics are derived such as cumulative distribution function, hazard rate function, second hazard rate function, mean residual life function, reverse hazard rate function, accumulated hazard rate function and also its order statistics. In addition, the study of the shapes of the hazard rate function is provided analytically and also by plots. Estimation of the parameters is done using the maximum likelihood method. A simulation study is conducted to assess the performance of the maximum likelihood estimators. Finally, the flexibility of the model is illustrated using three real data sets.
Isomorphism Check for Two-level Multi-Stage Factorial Designs with Randomization Restrictions via an R Package: IsoCheck
Authors: Batra Pratishtha , Spencer Neil , Ranjan Pritam 
Published: September 2023

Factorial designs are often used in various industrial and sociological experiments to identify significant factors and factor combinations that may affect the process re- sponse. In the statistics literature, several studies have investigated the analysis, con- struction, and isomorphism of factorial and fractional factorial designs. When there are multiple choices for a design, it is helpful to have an easy-to-use tool for identifying which are distinct, and which of those can be efficiently analyzed/has good theoretical properties. For this task, we present an R library called IsoCheck that checks the isomorphism of multi-stage 26n factorial experiments with randomization restrictions. Through representing the factors and their combinations as a finite projective geometry, IsoCheck recasts the problem of searching over all possible relabelings as a search over collineations, then exploits projective geometric properties of the space to make the search much more efficient. Furthermore, a bitstring representation of the factorial effects is used to characterize all possible rearrangements of designs, thus facilitating quick comparisons after relabeling.
This paper presents several detailed examples with R codes that illustrate the usage of the main functions in IsoCheck. Besides checking equivalence and isomorphism of 2^n multi-stage factorial designs, we demonstrate how the functions of the package can be used to create a catalog of all non-isomorphic designs, and good designs as per a suitably defined ranking criterion.

The impact of Covid-19 in Indonesia has not ended until November 28 2022 there is 36,057 people were exposed and 4,516,480 people were confirmed since the first Covid-19 declare. The government's anticipation during the January 2022 pandemic closed entry for arrivals from various countries through policy number 14 dated 13 October 2021 and No. 1 of 2022 concerning the behavior of entry points, quarantine places and RT-PCR obligations for Indonesian citizens traveling abroad for 10-14 days. International travelers, according to the Decree, are required to quarantine 5 x 24 hours for those who have been vaccinated and 14 x 24 hours from countries with a high escalation of positive cases. The policy was updated January 1 2022 for a 12x24 hour quarantine period, changing February 2022 to have an impact on the tourism industry, especially hospitality.
The hotel quarantine policy drew criticism after the Task Force issued a list of 66 hotels. Efforts to revive the hospitality industry through political economy. Public policy is the answer to the problem. Often policies conveyed through government communications foster crisis communication as a result of the contents of the message being conveyed there are irregularities. Crisis communication occurs when negative news about the difficulty and lengthy time of getting hotel quarantine colors the media pages.

Aim: Neo-adjuvant chemotherapy is a common approach for the complex treatment of breast cancer (BC) and paclitaxel (PTX) is frequently included in the therapeutic regimen. However, the effect of PTX-based treatment is hard to predict precisely based on routinely used markers. As microRNAs are considered a new promising class of biomarkers, the link between miRNA expression and PTX resistance of BC cells needs to be well investigated. This study aimed at the identification of miRNAs associated with responses of BC cells to PTX.
Methods: Intrinsic PTX sensitivity and miRNA profiling were assayed in five BC cell lines to identify candidate miRNAs. Selected miRNA (n. 15) expressions were analyzed by real-time-quantitative polymerase chain reaction (RT-qPCR) in BC tissue samples (n. 31) obtained from a diagnostic biopsy. Results were analyzed in the context of the effect of two cycles of PTX and the effect of the completed scheme of neoadjuvant therapy. The study’s design facilitated the evaluation of the effect of PTX on cells and the identification of features of the microRNA expression profiles associated exclusively with sensitivity to this drug.
Results: miR-186 and miR-7 expression in BC tissues was higher in patients with better outcomes of PTX-based neoadjuvant therapy.
Conclusion: High expressions of miR-186 and miR-7 are associated with good response to PTX, whereas their low expressions may be associated with resistance to PTX in BC, indicating the possibility of developing innovative test systems for the prediction of the PTX response, which can be used before the start of neo-adjuvant chemotherapy for BC.

Published: September 2023

Abstract
An experimental exploration research and comparison of the residual stress state between micro- and meso-milling processes with a ball-end mill on the Ti-6Al-4V titanium alloy were carried out. The residual stress state was analyzed based on the chip formation process according to the lead and tilt angles of the tool axis in relation to the normal vector to the surface. A novel idea was proposed to study the characteristic kinematics of a five-axis machining process, in a three-axis vertical machining center. When using the up-milling cutting strategy, it was found the defect of smeared/adhered material to the surface occurs in both the micro- and meso-milling levels, associated with the build-up edge and build-up layer phenomenon. The stress tensor of the surface was obtained using the X-ray diffraction technique. The down-milling cutting strategy produced the best surface finish and higher compressive residual stresses. Higher compressive residual stresses were found in the feed direction than in the cross-feed direction. The micro-milling process produced higher compressive residual stresses than those observed in the meso-milling process.

Abstract

Background Nearly 60% of patients with cancer have metabolic syndrome, which increases the risk of mortality, but there is no clear guidance for oncology providers about its management. Here, we report on the qualitative component of a larger mixed methods study that aimed to understand cancer patients’ knowledge, attitudes, and preferences regarding metabolic syndrome. Methods Adult cancer patients with metabolic syndrome were recruited during 2022–2023 in the MD Anderson General Internal Medicine clinic and participated in semistructured interviews focused on metabolic syndrome and lifestyle interventions. Interviews were audio-recorded and transcribed verbatim. Participants’ demographic information was collected. Interviews were analyzed using hybrid thematic analysis and constant comparison involving deductive and inductive coding. Researcher triangulation and debriefing were used to ensure rigor. Results There were 19 participants, 12 female and 12 White. Eighteen had solid tumors, including gynecologic (n = 5), genitourinary (n = 4), colorectal (n = 3), and breast (n = 2). Analysis yielded 5 major themes: 1) patients’ understanding of metabolic syndrome; 2) attitudes about and approaches to managing metabolic syndrome; 3) capacity and limitations regarding managing metabolic syndrome; 4) patient-led care; and 5) tailored intervention plans. Participants had limited knowledge of metabolic syndrome and its cancer-related consequences; most desired additional education. Many participants reported that their cancer or diabetes diagnosis motivated them to prioritize lifestyle modifications. Participants expressed strong interest in personalized care plans focused on healthy lifestyle rather than simply weight loss. As part of their tailored intervention plans, participants desired clear communication with their medical team, coordination of care among team members, and collaboration with providers about treatment decisions. Conclusion Cancer patients with metabolic syndrome want collaborative, patient-centered care. Shared decision-making based on respect for patients’ distinctive needs and preferences is an essential component of the development of such collaborative care. Tailored interventions, practical implementation strategies, and personalized care plans are needed for cancer patients with metabolic syndrome. The study findings contribute to filling the gap in knowledge regarding clear guidance for oncology providers on managing metabolic syndrome and will inform the development of future lifestyle interventions for patients diagnosed with metabolic syndrome.
