Published: September 2023

By definition, white noise (WN) is a type of sound that consists of a combination of various frequencies. Noise is an important source of environmental stress for humans and other living things and has a strong stimulating effect on light, circadian rhythm, hormonal, and neuro-behavioral levels. When faced with stressful situations, organisms produce a substantial quantity of free radicals, leading to alterations in the oxidative system. The objective of this research is to examine how environmental stressors like WN and light impact the activities of enzymes involved in testicular carbonic anhydrase (CA), catalase (CAT), and glutathione peroxidase (GPx). A total of 18 male Sprague-Dawley rats were divided into three groups. The first was the control group (not exposed to stress, kept at 12/12 light-dark cycle and 24±2°C normal ambient temperature). The second group, known as the WN 60' group, experienced 60 minutes of white noise exposure per day for 14 consecutive days at 90 dB. The third group, referred to as the WN 60' + non daylight group, underwent 60 minutes of white noise exposure at 90 dB combined with 24 hours of continuous light exposure every other day. At the conclusion of the study, the testicular tissues were homogenized and centrifuged, followed by the spectrophotometric measurement of enzyme activities.

As a result, when we compared the control group with both WN and WN + light exposure; A decrease was observed for CA enzyme in both applications, and an increase was observed in CAT and GPx enzymes in both applications.

As a result, when we compared the control group with both BG and BG + light exposure; A decrease was observed for CA enzyme in both applications, and an increase was observed in CAT and GPx enzymes in both applications.

Bu çalışmada gece vardiyalı sistemde çalışan intörn doktorların gece vardiyalı sistem öncesinde ve sonrasındaki mesleki tükenmişlik, uyku kalitesi ve melatonin değerlerinin değişimini incelemeyi amaçladık. Bu çalışma prospektif, tanımlayıcı ve kesitsel bir çalışmadır. Acil servis stajında gece vardiyalı sistemde çalışan intörn doktorlara gece vardiyalı sistem başladığı ve bittiği gün Maslach tükenmişlik ölçeği, Pittsburgh uyku kalite indeksi uygulandı. Ayrıca staj başında ve sonunda melatonin düzeylerinin belirlenmesi için kan örnekleri alındı. Uygulanan ölçek ve indeks uygun şekilde puanlandı. Melatonin değerleri uygun kitlerle çalışıldı. Elde edilen verilerin istatistiksel analizi yapıldı. Çalışmaya 45 gönüllü alındı. Gönüllülerin gece vardiyalı sisteme geçtikten sonraki duygusal tükenmişlik, duyarsızlaşma, kişisel başarısızlık oranları arttı (p değerleri sırası ile p=0,007, p=0,002, p=0,004). Gönüllülerin melatonin değerinde ise gece vardiyalı sisteme geçtikten sonra düşme gözlendi. Anca bu düşüş istatistiksel olarak anlamlı değildi (p=0,286). Gece vardiyalı sistem ile çalışmak mesleki tükenmişliği arttırır, uyku kalitesini bozar ve melatonin değerlerinde az da olsa düşmeye neden olur.

Published: September 2023

The aim of the study is to determine the perceptions and lived experiences of persons with a stoma. The study group of this qualitative study consisted of 14 persons with a stoma (ileostomy and colostomy) determined with the purposive sampling method. The data were collected using a semi-structured interview method and evaluated with the phenomenological analysis method. Three main themes emerged in the study; “unmet information needs”, “I am dependent and anxious”, and “the transition from one life to another”. Most of the persons with a stoma reported that preoperative information was not sufficient, and therefore they encountered difficulties in their later lives. Some participants think that the stoma has ended their independence, negatively affects their self-confidence and is a burden. It is necessary to provide adequate preoperative information to individuals who will have a stoma to ensure success in the process. This study provides comprehensive information about how a stoma and the physiological problems it causes affect persons’ lives and is believed to contribute to the planning and implementation of holistic care.

Blazars exhibit relentless variability across diverse spatial and temporal frequencies. The study of long- and short-term variability properties observed in the X-ray band provides insights into the inner workings of the central engine. In this work, we present timing and spectral analyses of the blazar 3C 273 using the X-ray observations from the XMM-Newton telescope covering the period from 2000 to 2020. The methods of timing analyses include estimation of fractional variability, long- and short-term flux distribution, rms–flux relation, and power spectral density analysis. The spectral analysis include estimating a model-independent flux hardness ratio and fitting the observations with multiplicative and additive spectral models such as power law, log-parabola, broken power law, and blackbody. The blackbody represents the thermal emission from the accretion disk, while the other models represent the possible energy distributions of the particles emitting synchrotron radiation in the jet. During the past two decades, the source flux changed by a factor of three, with a considerable fractional variability of 27%. However, the intraday variation was found to be moderate. Flux distributions of the individual observations were consistent with a normal or log-normal distribution, while the overall flux distribution including all observations appears to be rather multimodal and of a complex shape. The spectral analyses indicate that a log-parabola added to a blackbody gives the best fit for most of the observations. The results indicate a complex scenario in which the variability can be attributed to the intricate interaction between the disk/corona system and the jet.

Published: September 2023

Carbonaceous chondrites are among the most important meteorite types and have played a vital role in deciphering the origin and evolution of our solar system. They have been linked to low-albedo C-type asteroids, but due to subdued absorption bands, definitive asteroid–meteorite linkages remain elusive. A majority of these existing linkages rely on fine-grained (typically < 45 μm) powders across a limited wavelength range in the visible to near-infrared (0.35–2.5 μm). While this is useful in interpreting the fine-grained regolith of larger main-belt objects like Ceres, recent spacecraft missions to smaller near-Earth asteroids (NEAs), such as Bennu and Ryugu, have shown that their surfaces are dominated by larger grain size material. To better interpret the surfaces of these smaller, carbonaceous NEAs, we obtained laboratory reflectance spectra of seven carbonaceous chondrite meteorite groups (CI, CM, CO, CV, CR, CK, C2-ungrouped) over the ultraviolet to mid-infrared range (0.2–14 μm). Each meteorite contained five grain size bins (45–1000 μm) to help constrain spectral grain size effects. We find a correlation between grain size and absolute reflectance, spectral slope, band depth, and the Christiansen feature band center. Principal component analysis of grain size variation illustrates a similar trend to lunar-style space weathering. We also show that the Bus–DeMeo asteroid taxonomic classification of our samples is affected by grain size, specifically shifting CM2 Aguas Zarcas from a Ch-type to B-type with increasing grain size. This has implications for the parent body of the OSIRIS-REx target, Bennu. With Aguas Zarcas, we present results from Hapke modeling.

Published: September 2023

We report on a study of the mounds that dominate the appearance of Kuiper Belt Object (486958) Arrokoth's larger lobe, named Wenu. We compare the geological context of these mounds and measure and intercompare their shapes, sizes/orientations, reflectance, and colors. We find the mounds are broadly self-similar in many respects and interpret them as the original building blocks of Arrokoth. It remains unclear why these building blocks are so similar in size—and this represents a new constraint and challenge for solar system formation models. We then discuss the implications of this interpretation.

Purpose: An optimal once-daily radiotherapy (RT) regimen is under investigation for definitive concurrent chemoradiotherapy (CCRT) in limited disease small cell lung cancer (LD-SCLC). We compared the efficacy and safety of dose escalation with intensity-modulated radiotherapy (IMRT).Materials and Methods: Between January 2016 and March 2021, patients treated with definitive CCRT for LD-SCLC with IMRT were retrospectively reviewed. Patients who received a total dose <50 Gy or those with a history of thoracic RT or surgery were excluded. The patients were divided into two groups (standard and dose-escalated) based on the total biologically effective dose (BED, α/β = 10) of 70 Gy. The chemotherapeutic regimen comprised four cycles of etoposide and cisplatin.Results: One hundred and twenty-two patients were analyzed and the median follow-up was 27.8 months (range, 4.4 to 76.9 months). The median age of the patients was 63 years (range, 35 to 78 years) and the majority had a history of smoking (86.0%). The 1- and 3-year overall survival rates of the escalated dose group were significantly higher than those of the standard group (93.5% and 50.5% vs. 76.7% and 33.3%, respectively; p = 0.008), as were the 1- and 3-year freedom from in-field failure rates (91.4% and 66.5% vs. 73.8% and 46.9%, respectively; p = 0.018). The incidence of grade 2 or higher acute and late pneumonitis was not significantly different between the two groups (p = 0.062, 0.185). Conclusion: Dose-escalated once-daily CCRT with IMRT led to improved locoregional control and survival, with no increase in toxicity.

Published: September 2023

Non-suicidal self-injury (NSSI) is highly prevalent among adolescents. The current study aimed to explore defense mechanisms and parental styles of adolescents with NSSI behaviors. The Egna Minnen Barndoms Uppfostran (EMBU [One's Memories of Upbringing]) and Defense Style Questionnaire (DSQ) were used to evaluate 31 participants with NSSI behaviors in the experimental group and 60 participants with non-NSSI behaviors in the control group. There were significant differences in Father Factors II, V, and VI, and Mother Factors III and IV on the EMBU between the experimental and control groups. On the DSQ, there were significant differences in immature defense mechanism, mature defense mechanism, and camouflage factors between the experimental and control groups. In the experimental group, Father Factors I and IV and Mother Factors I and V were significantly correlated with mature defense mechanism. Father Factor VI and Mother Factors III and IV were significantly correlated with immature defense mechanism. Father Factors II and V were significantly correlated with camouflage factors. Defense mechanisms and parental styles of participants in the experimental group were different than those of the control group, and immature parental styles affect the formation of defense mechanisms.

In this paper, we find solutions and investigate the superstability bounded by a function (Gǎvruta sense) for the $ p $-power-radical functional equation related to sine function equation:

   \begin{document}$ \begin{equation*} f\left(\sqrt[p]{\frac{x^{p}+y^{p}}{2}}\right)^{2} -f\left(\sqrt[p]{\frac{x^{p}-y^{p}}{2}}\right)^{2} = f(x)f(y) \end{equation*} $\end{document}

from an approximation of the $ p $-power-radical functional equation:

   \begin{document}$ \begin{align*} f\left(\sqrt[p]{\frac{x^{p}+y^{p}}{2}}\right)^{2} -f\left(\sqrt[p]{\frac{x^{p}-y^{p}}{2}}\right)^{2} = g(x)h(y), \end{align*} $\end{document}

where $ p $ is a positive odd integer, and $ f, g $ and $ h $ are complex valued functions on $ \mathbb{R} $. Furthermore, the obtained results are extended to Banach algebras.
On a SEIR-type model of COVID-19 using piecewise and stochastic differential operators undertaking management strategies

Published: September 2023

In this work, an epidemic model of a susceptible, exposed, infected and recovered SEIR-type is established for the distinctive dynamic compartments and epidemic characteristics of COVID-19 as it spreads across a population with a heterogeneous rate. The proposed model is investigated using a novel approach of fractional calculus known as piecewise derivatives. The existence theory is demonstrated through the establishment of sufficient conditions. In addition, result related to Hyers-Ulam stability is also derived for the considered model. A numerical method based on modified Euler procedure is also constructed to simulate the approximate solutions of the proposed model by employing various values of fractional orders. We testified the numerical results by using real available data of Japan. In addition, some results for the SEIR-type model are also presented graphically using the stochastic process, and the obtained results are discussed.
A boundary value problem of heat transfer within DBD-based plasma jet setups

Published: September 2023

We claim an analytical solution for the thermal boundary value problem that arises in DBD-based plasma jet systems as a preliminary and consistent approach to a simplified geometry. This approach involves the outline of a coaxial plasma jet reactor and the consideration of the heat transfer to the reactor solids, namely, the dielectric barrier and the grounded electrode. The non-homogeneous initial and boundary value thermal problem is solved analytically, while a simple cut-off technique is applied to deal with the appearance of infinite series relationships, being the outcome of merging dual expressions. The results are also implemented numerically, supporting the analytical solution, while a Finite Integration Technique (FIT) is used for the validation. Both the analytical and numerical data reveal the temperature pattern at the cross-section of the solids in perfect agreement. This analytical approach could be of importance for the optimization of plasma jet systems employed in tailored applications where temperature-sensitive materials are involved, like in plasma biomedicine.

Published: September 2023

Objectives: This study investigated the association between baseline exposures to particulate matter with a diameter < 2.5 microns (PM2.5) and subsequent temporal changes in PM2.5 exposure with the incidence of type 2 diabetes among Royal Thai Army personnel.Methods: A retrospective cohort study was conducted using nationwide health check-up data from 21 325 Thai Army personnel between 2018 and 2021. Multilevel mixed-effects parametric survival statistics were utilized to analyze the relationship between baseline (i.e., PM2.5-baseline) and subsequent changes (i.e., PM2.5-change) in PM2.5 exposure and the occurrence of type 2 diabetes. Hazard ratios (HRs) and 95% confidence intervals (CIs) were employed to assess this association while considering covariates.Results: There was a significant association between both PM2.5 baseline and PM2.5-change and the incidence of type 2 diabetes in a dose-response manner. Compared to quartile 1, the HRs for quartiles 2 to 4 of PM2.5-baseline were 1.11 (95% CI, 0.74 to 1.65), 1.51 (95% CI, 1.00 to 2.28), and 1.77 (95% CI, 1.07 to 2.93), respectively. Similarly, the HRs for quartiles 2 to 4 of PM2.5-change were 1.41 (95% CI, 1.14 to 1.75), 1.43 (95% CI, 1.13 to 1.81) and 2.40 (95% CI, 1.84 to 3.14), respectively.Conclusions: Our findings contribute to existing evidence regarding the association between short-term and long-term exposure to PM2.5 and the incidence of diabetes among personnel in the Royal Thai Army.

Published: September 2023

Objectives: The association between long sleep duration and mortality is frequently attributed to the confounding influence of comorbidities. Nevertheless, past efforts to account for comorbidities have yielded inconsistent outcomes. The objective of this study was to evaluate this relationship using a large prospective cohort in Korea.Methods: The study included 114 205 participants from the Health Examinees Study, who were followed for a median of 9.1 years. A composite comorbidity score was developed to summarize the effects of 21 diseases. Using Cox proportional hazards regression, hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause, cancer, and cardiovascular mortality associated with sleep duration were estimated. These estimates were adjusted for socio-demographic factors, lifestyle factors, body mass index, and comorbidity score. Additionally, a stratified analysis by subgroups with and without comorbidities was conducted.Results: Throughout the follow-up period, 2675 deaths were recorded. After all adjustments, an association was observed between a sleep duration of 8 hours or more and all-cause mortality (HR, 1.10; 95% CI, 1.01 to 1.20). However, no such association was detected in the stratified analysis for the subgroups based on comorbidity status.Conclusions: Long sleep duration was found to be associated with all-cause mortality among Koreans, even after adjusting for comorbidities. Additional studies are required to explore the mechanism underlying the association between sleep duration and major causes of mortality.
La restauration de la fontaine des Innocents à Paris

Published: September 2023

Dans le cadre du programme de mise en valeur de ses fontaines, la Ville de Paris a lancé une campagne de restauration de la fontaine des Innocents, chef-d’œuvre de la Renaissance française. Le but de ce chantier est double : déposer, après 130 ans de débat, les bas-reliefs originaux érodés par les intempéries, les restaurer, les remplacer par des reproductions, puis remettre en eau la fontaine afin de lui restituer sa fonction première.L’évolution des usages liés à l’eau de la fontaine au gré de ses déplacements et mutations sera d’abord abordée grâce à une analyse iconographique. Initialement située à un angle de rue, la fontaine a été utilisée pour la distribution d’eau potable, l’hygiène publique et individuelle, et son usage a drainé des professions spécifiques. Les progrès d’adduction d’eau et son déplacement du centre d’une place à un square aidant, elle se transforme en l’objet patrimonial que l’on connaît aujourd’hui. Seront ensuite traités le programme sculpté de cette fontaine, dont les célèbres bas-reliefs sont sur le thème de l’eau, et le renouvellement récent des connaissances sur le degré d’authenticité du monument dans son ensemble.Enfin, il sera question des enjeux techniques et doctrinaux du chantier de restauration. Il s’agira d’analyser la question de la reproduction des sculptures, des nouvelles technologies qui seront mises à profit pour cela, mais aussi de la mise en lumière du monument.Les enjeux actuels posés par cette fontaine en termes d’hygiène publique et leur impact pour le monument permettront de conclure cet article.

Les bains-douches scolaires
Authors: Rossi Pauline
Published: September 2023

Les services de la Ville de Paris ont découvert en 2020 une installation de bains-douches dans les sous-sols d’une école du 14e arrondissement, équipement qui n’était pas destiné à une population adulte, mais aux élèves. Dans l’historiographie de l’architecture scolaire, sujet largement traité par l’architecte et historienne Anne-Marie Châtelet, il est apparu que la question de l’apprentissage de l’hygiène à l’école était restée parmi les angles morts de la recherche. Une enquête, associant divers services de la Ville, a donc été lancée afin de recenser les équipements existants. Deux seulement ont pu être découverts : le premier dans l’école du 12, rue d’Alésia (14e arr.), le second dans l’école du 5, rue Beauregard (2e arr.).Parallèlement à cette enquête, des recherches en archives ont permis de comprendre le contexte de la création de ces aménagements oubliés, mais aussi d’évaluer l’importance du dispositif à l’échelle de la capitale. Si le travail n’a pu être exhaustif, il a donné lieu à un inventaire indicatif, recensant vingt installations, créées entre les années 1880 et 1930. C’est ainsi qu’a été redécouvert un sujet majeur, tant pour le patrimoine bâti des établissements d’écoliers parisiens, que pour l’histoire de l’apprentissage de l’hygiène à l’école.

Malicious applications can be a security threat to Cyber-physical systems as these systems are composed of heterogeneous distributed systems and mostly depends on the internet, ICT services and products. The usage of ICT products and services gives the opportunity of less expensive data collection, intelligent control and decision systems using automated data mining tools. Cyber-physical systems become exposed to the internet and the public networks as they have integrated to the ICT networks for easy automated options. Cyber-attacks can lead to functional failure, blackouts, energy theft, data theft etc. and this will be a critical security concern for Cyber-physical systems. There have been many instances of cyber-attacks on CPS systems earlier, the most popular being the Stuxnet virus attack. In total there have been 7 instances of such attacks on CPS systems that have the potential to totally cripple critical infrastructures causing huge business impacts including loss of life in some cases. Earlier these CPS or process level systems used to work in an isolated manner with very less intelligence, but as the convergence between CPS and IT is increasing their cyber-attack surface is increasing for threat actors to exploit. Therefore, in this chapter, the authors shall be seeing the technical threats in the form of malware which can exploit the CPS systems and how it can be protected from cyber-attacks.

Published: September 2023

In this cyber world, working from the office to the home, security has never been more challenging. To detect attacks on the host computers and prevent further malicious activities, host intrusion detection systems (HIDS) are often used. Use of open-source SEIM tool Wazuh for monitoring and combines with YARA for file analysis. YARA rules are like those of a programming language that operates by specifying variables that indicate patterns identified in malware, depending on the rule. If any or all the conditions are satisfied, it can be used to effectively identify at least a portion of malware that defines variable parameters. YARA rules help SIEM operators analyse the file tag for malware detection before using it to its full potential. In this chapter, we are going to learn and implement malware analysis using Wazuh, and YARA rules before infecting the system fully. A flexible and effective method for detecting malware in system logs, network traffic, and other data sources is produced by combining WAZUH and YARA rules. By utilising the advantages of YARA rules and the sophisticated features of WAZUH, security teams can quickly identify malware attacks and respond to them. This lessens the effect on their business. A modern cybersecurity strategy must contain WAZUH SIEM and YARA rules. With YARA rules, security teams may spot malware attacks in WAZUH and take appropriate action to maintain the security and integrity of their organization's data and systems.

Authors: Owusu-Agyeman Yaw , Moroeroe Enna
Published: September 2023

As higher education institutions attempt to address issues pertaining to institutional change, very few scholarly studies have examined how transformational leadership processes influence changes to institutional cultures and structures. To address this gap, the current study explores how leadership processes contribute to changes in the institutional culture and structure of a university in South Africa by gathering interview data from 69 academic and professional staff. The findings revealed that for the university to achieve its transformation objectives, leaders should challenge the cognitive abilities of their staff, scaffold strategies for meeting high work standards, negotiating the attainment of staff personal and career goals, engender staff motivation and assist their staff to understand the institutional culture and structure. These findings among others lead the author to propose ways that future studies could examine how the leadership processes could enhance institutional transformation.
Investigating the Effects of SHRM on Operational and Financial Performance in Educational Institutions
Authors: Kumah Peace
Published: September 2023

Strategic human resource management (SHRM) seeks to create alignment between human resource management (HRM) practices and business strategy (strategy fit); linking HR strategies, policies, and practices within the functional units of the HR department (intra-functional fit); maintaining the status of the HRM department within corporate strategic plan (HR-roles-position fit); and alignment of HRM functions with all other departments (cross-functional fit). This study investigates the effects of SHRM on organizational performance. Data was collected from 314 employees in tertiary educational institutions in Ghana. A conceptual model was developed and a set of hypotheses were proposed. The results found that cross-functional fit has a significant effect on both financial and operational performance. However, the results found no significant effect of strategy fit, role-position fit, and intra-functional fit on financial and operational performance. Therefore, tertiary educational institutions should develop cross-functional fit to improve their financial and operational performance.
