Accentuated Eccentric Load Training: Traditional Set Versus Cluster Set
(Iermakov S S, 2022) Ersoz, Mehmet; Pinar, Salih; Kaya, Selman
Background and Study Aim Material and MethodsThis study aims to comparatively analyse the effects of cluster set (CS) and traditional set (TS) applications on strength and power outputs in accentuated eccentric load (AEL) training. Thirty-two amateur male football players with at least 2 years of strength training history participated in the study (Xage: 18,78 +/- 0,83 years, Xheight:166,73 +/- 8,61 cm., Xbody weight: 69,59 +/- 6,03 kg.). Participants were randomly divided into two groups: CS (n=16) and TS (n=16). In both groups, the same "AEL Training" was applied and different set models were used. Augmented eccentric load (AEL) training was performed with 3 sets of 8 repetitions, 50% concentric and 80% eccentric of 1 Repetition Maximum (1-RM) and with a fast lifting tempo. The sets were completed with 20 seconds of rest after every two repetitions in the AEL-CS group and without any rest between repetitions in the AEL-TS group, and the training sessions were performed twice a week for 4 weeks. Countermovement jump (CMJ), 50cm drop jump-reactive strenght index (DJ-RSI) test, 1-RM strenght test, 10-20-30m sprint test and Illinois Agility Test (IAT) were performed on the athletes before and after the training.ResultsWhen analysing the data obtained in this study, Skewness and Kurtosis values and Kolmogorov-Smirnov values were examined to determine homogeneity. In order to compare the pre-test and post-test averages between groups, ANOVA was used for Repeated Measures, and Sample T Test was used to compare the pre-test and post-test averages within groups. The statistical significance level was determined as p<0.05. When the groups were compared, the difference in the improvement rate averages was tested. At the end of the four-week study, drop jump-reactive strength index (DJ-RSI), countermovement jump (CMJ), Illinois Agility Test (IAT) 10-20-30m sprint values and 1-RM values were improved percentage-wise in both AEL-CS and AEL-TS groups. Between the groups, a significant difference was observed between DJ-RSI, CMJ, and 10-20-m Sprint Test results (p<0.05). When we compare the results within groups, it can be concluded that the AEL-CS group showed more improvement in terms of strength, change of direction (COD) skills and Sprint compared to the AEL-TS group.ConclusionsIn conclusion, it can be advised to use cluster set in accentuated eccentric load training in order to improve strength, Sprint and COD skills.

(Springer, 2026) Aminizadeh, Selva; Alizadeh, Gita; Alizadeh, Zahra; Khalilzadeh, Balal; Abidin, Zurina Zainal; Marzi, Mahdi; Rafiei-Sefiddashti, Raheleh
Parasitic diseases are among the most widespread infections worldwide, causing millions of deaths and illnesses each year. So rapid and accurate diagnosis is essential, requiring highly sensitive and specific tests. Biosensors can provide significant advantages over traditional diagnostic methods because of their specificity, sensitivity, speed, simplicity, ease of use, repeatability, and capacity for early-stage disease detection. Recent advances in modern diagnostic tools for detecting parasitic infections use nanomaterials such as gold nanoparticles, carbon nanofibers, and carbon nanotubes. These developments have significantly lowered detection limits to the picogram and femtogram levels. This review will cover recent advancements in biosensor-based diagnostic techniques in parasitology.

(Ankara Univ, 2025) Saçan, Ozlem; Şener, Göksel; Yanardag, Refıye; Tunali-Akbay, Tugba; Sivas, Guzin Goksun; Karaoğlu, Sümeyye Yılmaz; Dursun, Ercan
Methotrexate (MTX) is a widely used antiarthritic and chemotherapeutic agent known to cause damage to various tissues. This study investigated the potential protective effects of parsley extract against MTX-induced brain and intestinal tissue damage. Sprague-Dawley rats were divided into control, control + parsley, MTX, and MTX + parsley. MTX (20 mg/kg, i.p.) was administered to the MTX and MTX + parsley groups. The control + parsley, and MTX + parsley groups were administered 2 g/kg parsley extract by oral gavage for five consecutive days. After the fifth day, brain and small intestinal tissues were taken. Total protein, nitric oxide, lipid peroxidation, glutathione levels, tissue factor, superoxide dismutase, and glutathione S-transferase activities were determined in these tissues. The protein profiles of the tissues were evaluated using SDS polyacrylamide gel electrophoresis. Parsley administration caused a decrease in lipid peroxidation levels in both tissues of the MTX group. On the other hand, glutathione level, glutathione-S-transferase, and superoxide dismutase activities were found to be increased. On the other hand, parsley decreased the nitric oxide level which was increased in the intestinal tissues of the MTX group. There was no significant change in brain nitric oxide level and tissue factor activity between groups. MTX and parsley administration altered protein expression, leading to the appearance or disappearance of specific bands in intestinal and brain tissues. In conclusion, parsley alleviated MTX-induced damage in brain and intestinal tissues by reducing lipid peroxidation and modulating antioxidant defenses.
Assessment of Artificial Lighting Conditions in Sunlight-Deprived Classrooms
(Gazi Univ, Fac Engineering Architecture, 2025) Duyan, Fazila; Kaplan, Elif
Numerous studies on classroom lighting emphasize a close and significant relationship between students' concentration, comprehension of course content, and the efficiency of activities such as drawing, writing, and practices, with the lighting conditions. In this context, it is particularly important to properly design both the physical and psychological effects of artificial lighting, especially in sunlight-deprived classrooms. This study examines the artificial lighting conditions of a classroom located in the basement of a university building, which has no visual connection to the outdoors. The classroom is utilized by students from the departments of Architecture, Interior Architecture, and Industrial Design. The study investigates the effects of current artificial lighting on students, focusing on aspects such as visual perception satisfaction, light colour, illuminance level, glare, and the temporal light modulation effect. To assess students' perception of the existing lighting conditions, an online questionnaire was administered, and a total of 104 students (65 female, 39 male) who had previous experience with the classroom participated in the study. Technical measurements of the existing luminaires were conducted, and the classroom was digitally modelled using the DIALux Evo lighting software. The collected data were analysed using the SPSS statistical analysis program. The findings of the study indicate that students perceived the artificial lighting conditions as inadequate in terms of visual comfort. Moreover, based on technical measurements, simulations, and user evaluations, it was determined that the existing luminaires caused glare and temporal light modulation effects, negatively affecting the classroom environment.

Balance Training in Modern Dancers Proprioceptive-Neuromuscular Training Vs Kinesio Taping
(Science & Medicine inc, 2018) Tekin, Demet; Agopyan, Ani; Baltaci, Gul
Kinesio tape and proprioceptive exercises are both used for increasing balance in dancers. The purposes of this study were to: a) determine the acute effect of kinesio tape (KT) application on the ankle joint on balance performance, b) investigate the effects of an 8-week proprioceptive-neuromuscular (PN) training program on balance performance, and c) compare their effects vs modern dance technique classes alone. Thirty-three trained, university-level modern dance students (9 male, 24 female) were divided randomly into three groups: kinesio tape (KT, n=11), proprioceptive-neuromuscular (PN, n=11), or control (n=11). Static (turn-out passe-opened eyes/releve and turn-out passe-closed eyes/flat foot), semi-dynamic (airplane), and dynamic balance (monopodalic-straight and -transverse in a turn-out passe-eyes opened/flat foot) tests were performed before and after the intervention. One day after pre-tests, KT mechanical correction technique was applied to the left ankle joint (supporting leg) in the KT group, and tests were repeated to determine the acute effect of KT. The PN group participated in an 8-week balance training program (2 days/wk, 60 min/day) involving exercises using stable and unstable surfaces. Significant improvements were observed for all static and dynamic balance tests in the PN group; semi-dynamic airplane and dynamic monopodalic-straight and transverse tests improved in the KT group; and only semi-dynamic airplane test scores changed significantly for the control group (p<0.05). Our findings suggest that with the exception of the semi-dynamic airplane test, both PN training and KT application were more effective at improving balance performance for modern dancers than modern dance technique classes alone.

Comparison of Motorcyclists' Hand Grip Strength and Reaction Time
(Asoc Didactica Andalucia, 2022) Tekin, D.; Agopyan, A.
The purpose of this study was to compare hand grip strength and reaction times in male motorcycle racers grouped according to different ages and the classes of motorcycle used and determine the relation between these characteristics. Sixty-five healthy male motorcycle racers were divided into four groups according to their age and the power of the motorcycles' engine: (Group-1 [G1] = 600CC/23-34 years; Group-2 [G2] = 600-CC/35-48 years; Group-3 [G3] = 1000-CC/23-34 years; Group-4 [G4] = 1000-CC/35-48 years). Then, Nelson's reaction time and maximal hand grip strength were measured for both hands. There were no significant differences between the groups' grip strength (p>0.05). It was found that G1's right-and left-hand reaction time was faster than that of G2, and G1's left-hand reaction time was faster than that of G3 (p<0.05). The right-hand visual reaction time was found to have a negative weak correlation with the left-hand absolute grip strength (r=-0.247, p=0.047), and there was a weak positive correlation between the left-hand visual reaction time and height (r=0.315, p=0.011). G1's right-hand visual reaction time was better than that of G2 (p < 0.001), and G1's visual left-hand reaction time was better than those of G2 (p < 0.034) and G3 (p < 0.011). Although the absolute and relative hand grip strength values did not differ according to the ages and the engine power of the motorcycle used, it was found that the simple reaction time increased with increasing age.

Comparison of Total Antioxidant Capacities and Phenolic Constituents of Grapes Cultivated in Turkey for Wine Production
(Taylor and Francis Ltd., 2025) Karaman Ersoy, Ş.; Vural, T.; Sözgen Başkan, K.; Tütem, E.
Grapes are renowned for their health-promoting properties due to polyphenols, particularly anthocyanins in red grapes and flavonols in white grapes. This study evaluated the total antioxidant capacities (TAC) of specific grape varieties (Sultaniye, Chardonnay, Shiraz, Carignan, Alicante Bouschet, and Merlot) using the CUPRAC (CUPric Reducing Antioxidant Capacity) and ABTS/HRP (2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)/horseradish peroxidase) methods. Additionally, total phenolic, flavonoid, and anthocyanin contents were determined via Folin Ciocalteu, AlCl3/NaNO2, and pH differential methods. Primary phenolic compounds were identified with High-Performance Liquid Chromatography-Photodiode Array (HPLC-PDA). TAC values of the grape juices (mmol Trolox L−1) ranked as Alicante > Shiraz > Sultaniye > Carignan > Merlot > Chardonnay by CUPRAC, and Shiraz > Alicante > Merlot > Carignan ≥ Sultaniye > Chardonnay by ABTS/HRP and for skin extracts (mmol Trolox g−1), Carignan > Alicante > Shiraz > Merlot > Chardonnay > Sultaniye by CUPRAC, and Carignan > Shiraz > Alicante > Merlot > Chardonnay > Sultaniye by ABTS/HRP. The study demonstrated a strong correlation between phenolic composition and TAC values in grape samples, with anthocyanins as the predominant family contributing significantly to TAC. Varietal and intra-fruit differences in specific phenolic compounds were found to account for variations in observed TAC levels. Specifically, grape skin samples showed a more robust correlation between antioxidant capacity and total phenolic content (r = 0.986) than grape juices (r = 0.777). These findings underscore the considerable variation in antioxidant potential among grape varieties and emphasize the critical role of phenolic composition in the health-related benefits of grape consumption. © 2024 Taylor & Francis Group, LLC.

(Tubitak Scientific & Technological Research Council Turkey, 2022) Kazma, Coskun; Levent, Vecdi Emre; Cardak, Merve; Aydin, Nizamettin
When central nervous system has a problem, somatic area I and II respond to stimulation differently. Therefore, it is possible to identify some of the central nervous diseases when somatosensory on the fingertip is stimulated and responses are recorded and analyzed. We designed a system to stimulate the mechanoreceptors on fingertips. It is composed of a mechanical system for fingertip stimulation, an embedded controller, a control computer, and a software to control overall operation. During test, mechanoreceptors are stimulated according to the test protocols. Individuals' answers are recorded to be evaluated by the developed software. In this study, several design approaches for embedded controller were also examined and an FPGA based controller with the same functionality but higher performance was implemented. A test procedure was performed on 51 individuals at the department of pediatric psychiatry in a hospital, to investigate whether the sex has an effect on attention deficit and hyperactivity disorder.

Design, Synthesis, and in Vitro and in Vivo Anticancer Activity Studies of New (s)-naproxen Thiosemicarbazide/1,2,4-triazole Derivatives
(Royal Soc Chemistry, 2022) Han, M. Ihsan; Tunc, Cansu Umran; Atalay, Pinar; Erdogan, Omer; Unal, Gokhan; Bozkurt, Mehmet; Kucukguzel, S. Guniz
In this study, a series of novel (S)-Naproxen derivatives bearing a thiosemicarbazide/1,2,4-triazole moiety were designed, synthesized, and evaluated for anticancer activity. The structures of these compounds were characterized by spectral (H-1-C-13 NMR, FT-IR, and HR-MS analyses) methods. All of the synthesized compounds (3a-m, 4a-j) were screened for anticancer activity against human breast cancer cell line MDA-MB-231. Among them, (S)-4-(2,4-dichlorophenyl)-5-[1-(6-methoxynaphthalen-2-yl)ethyl]-4H-1,2,4-triazole-3-thione (4b) showed the most potent anticancer activity with a good selectivity (IC50= 9.89 +/- 2.4 mu M). Inhibition of anti-apoptotic protein Bcl-2 was investigated in MDA-MB-231 cells treated with compound 4b using Western Blotting. Apoptosis was also detected by AO/EB and JC-1 staining. Furthermore, activation of caspase-3 enzyme activity demonstrated apoptosis. The flow cytometric analysis results showed that compound 4b decreases the number of cells in the G2/M phase and increases the cells in the S phase in a dose-dependent manner. The anticancer activity of compound 4b was also investigated. In the Ehrlich acid tumor model, a well-validated in vivo ectopic breast cancer model, compound 4b had anticancer activity and reduced the tumor volume at both low (60 mg kg(-1)) and high (120 mg kg(-1)) doses in mice, according to our in vivo results.

Determination of Chemical Composition and Antioxidant, Cytotoxic, Antimicrobial, and Enzyme Inhibition Activities of rumex Acetosella L. Plant Extract
(Springer int Publ Ag, 2024) Kandemir, Sevgi Irtegun; Aktepe, Necmettin; Baran, Ayse; Baran, Mehmet Firat; Atalar, Mehmet Nuri; Keskin, Cumali; Khalilov, Rovshan
Purpose The phenolic composition, antioxidant, antimicrobial activity, enzyme inhibition activity, and cytotoxic activity potentials of the plant Rumex acetosella L. (R. acetosella) were examined in this study. Materials and Methods: The chemical composition of R. acetosella methanol extract was identified by the LC-MS/MS method. The antioxidant activity was tested using beta-carotene/linoleic acid, DPPH free radical scavenging, ABTS cation radical scavenging, CUPRAC reducing power, and metal chelating activity methods. The cytotoxic activity was determined by the MTT assay using human ovarian adenocarcinoma (Skov-3), glioblastoma (U87), human dermal fibroblasts (HDF), and human colorectal adenocarcinoma (CaCo-2) cell lines. The antimicrobial activity of methanolic extracts was tested on gram-negative (Escherichia coli and Pseudomonas aeuriginosa) and gram-positive bacteria (Staphylococcus aureus and Bacillus subtilis) using the in vitro minimum inhibition concentration method (MIC). Enzyme inhibition activity of R. acetosella methanol extract was measured spectrophotometrically against acetylcholinesterase (AChE) and glutathione S-transferase (GST) enzymes. Results: The findings showed that the major components of the methanol extract content were luteolin-7-O-glucoside (1.599 m/L), polydatin (91,024 m/L), and shikimic acid (0.773 m/L). It was determined that the extract and standard antioxidant (a-tocopherol) results in DPPH center dot, and ABTS center dot + tests performed to determine the antioxidant activity were close to each other, and this value was more effective than the standard antioxidant (alpha-tocopherol) in the CUPRAC test. These results suggested that the plant's antioxidant potential was higher when compared with reference antioxidant compounds. It was determined that the methanol extract of R. acetosella had a weaker effect on the growth of the tested microorganisms than the antibiotics used as standard. The activity of the GST and AChE enzymes was found to be severely inhibited by the methanol extract of R. acetosella. Conclusion: Based on these findings, R. acetosella L. is a medicinal and commercially beneficial plant that warrants further investigation.

Determining the Effect of Urbanization on the Vegetation of Gurun District (sivas) Based on Biotope Mapping and Vegetation Analysis
(Istanbul Univ-cerrahapasa, 2020) Bozkurt, Selvinaz Gulcin; Akkemik, Unal; Kose, Nesibe
Urbanization is one of the strongest negative effects on vegetational change within and around a city. In this study, it is aimed to determine the flora and vegetational changes within and around the city based on the identification and mapping of the biotopes which show differences in terms of ecologic factors met in Gurun district center and its vicinity and which are suitable for Corine biotope classification. First, 13 main biotope types are classified. In the biotopes, total 666 plant taxa were identified, 84 of which were endemic. Vegetation of the biotopes was determined, and then similarity levels of main biotopes are calculated according to the similarity coefficient method of Sorensen. Accordingly, while the similar areas are health facilities and agricultural areas the most different ones are parks and sports areas and drainage areas. The results emphasize the similarity levels of vegetation in biotopes and the negative effect of human intervention in the study area. As a result, with its rich natural structure, vegetation covers and endemism rate, the district of Gurun has significant natural biotopes and it is suggested that biotope classification should be considered in determining vegetation change and urban planning.

Digitalization of Memories - an Analysis Relationship Between Autobiographical Memory and Digital Photography
(Univ Ss Cyril & Methodius Trnava, Fac Mass Media Communication, 2020) Keskin, Aysun Eyrek
Photography has been used as a mnemonic since its early years. It has the power to move the past to the present by breaking down the structure of time. Presenting a static image, it records an image of a past time. Looking through family and childhood photo albums, the person embarks on a journey through the past in his/her memory. Following digitalization, the function of photography has been changed in accordance with the transformation of it from analogue to digital. Photography is not only a mnemonic but also contains the function of the enjoyment of individuals, creating self, self-presenting to others. In terms of storage, screening and sharing, digital photography is more convenient and accessible than analogue photography. For these reasons, people's interest in digital photography has been rising and it encourages taking/recording images at the moments that will create their memories in the years ahead. The aim of this paper is to examine the relationship between autobiographical memory (contains information about individual experiences, memories) and forgetting/remembering between digital photography. The nature of the subject required the use of both qualitative and theoretical analysis of the participants' social media usage. The research data was collected conducting semi-structured interviews with participants who shared their images about individual lives and memories on social media. In addition, benefiting from the observation technique, the participants were requested to look at both printed and digital photo albums and asked if they remember the corresponding memories. The theoretical insights are based on critical theory. The studies reveal that memories become digital and affect memory due to rising motivation to take and share pictures on the social media.

(Springer, 2023) Urfa, Osman; Asci, Fevziye Hulya
The aim of this study was to examine the relationship between irrational beliefs and perceived performance and the atemporal mediator role of emotions and automatic thoughts in this relationship. A cross-sectional study design with a convenient sampling method was used in the study. Participants included 395 athletes from basketball, football, handball, and volleyball and consisted of 267 male (Mage = 20.73, SD = 2.37) and 128 female (Mage = 21.33, SD = 2.17) athletes who voluntarily participated in the study. Data was analyzed via a path analysis and irrational beliefs were shown to negatively predict positive emotions and positive automatic thoughts, but these beliefs positively predicted negative emotions and negative automatic thoughts. The direct effect of irrational beliefs on perceived performance was not significant, but its indirect effect on perceived performance through emotions and automatic thoughts was significant. Irrational beliefs negatively predict perceived performance through emotions and automatic thoughts. It is concluded that emotions and automatic thoughts play a significant role in the relationship between irrational beliefs and perceived performance.

Disaster Risk Perception and Sustainable Earthquake Awareness Among Public and Private University Nursing Students
(Wiley, 2024) Kolac, Nurcan; Eroglu, Nermin; Nirgiz, Cansu
Background: This research was conducted in descriptive type to determine the disaster risk perception and sustainable earthquake awareness of nursing students studying at public and private universities. Methods: The study sample consisted of 400 nursing students studying at one public and one private university. The research was conducted between April and May 2023. The data were collected using a Sociodemographic Form, University Students Disaster Risk Perception Scale (USDRPS), and Sustainable Earthquake Awareness Scale (SEAS). Data were collected online using a questionnaire created on Google Forms. Analyses included frequency, percentage, mean, standard deviation values, independent groups t-test, post-hoc Tukey test, LSD, and ANOVA test. Results: Of the students, 61.8% had a disaster experience, 17.4% had lost a relative in the disaster, and 76.8% did not consider themselves prepared for a possible disaster. In the study, the exposure sub-dimension score of the disaster risk perception scale was found to be higher in students who had disaster experience than in those who did not (p = 0.032). Nursing students from the private university had higher sustainable earthquake awareness scores than those studying at the state university (p = 0.001). The mean scores of female students on the earthquake preparedness and preparation application sub-dimensions showed a significant difference compared to the scores of male students (p = 0.016). In the study, sustainable earthquake awareness total and earthquake preparedness sub-dimension scores were higher in second-year nursing students than in students of other years (p = 0.042; 0.015). Those who had received disaster training had low scores on the uncontrollable sub-dimension of the disaster risk perception scale, and high scores on the total SEAS and earthquake-structure relationship, earthquake preparedness, and earthquake preparation application sub-dimensions (p < 0.05). Conclusions: In the study, three out of four students did not find themselves prepared for disasters. Those who had disaster experience had higher disaster risk perceptions. Students who had received disaster-related training had more positive earthquake preparedness, earthquake-structure relationship, and earthquake preparation applications than those who had not. Students who were female and were in the second year had higher earthquake awareness. Studies can be carried out to inform people about the pre-disaster and preparation stages to raise awareness about disasters at universities. Education on disaster management can be integrated into courses from the first years of university.

(Kare Publ, 2024) Cevik, Ozge; Sen, Ali; Şener, Göksel; Ercan, Feriha; Doğan, Ahmet; Özbeyli, Dilek; Hatipoğlu, Bilge Nur
OBJECTIVE: In our study, the protective effect of dodder plant extract against encephalopathy induced by cholestatic liver disease model was investigated. METHODS: Spraque Dawley rats were used in the study. For the cholestatic liver disease model, the bile duct ligation (BDL) was applied. The groups were determined as control, Cuscuta sp. (CUS), BDL and BDL + CUS. Double ligation was performed in the bile duct in the BDL groups. For the applications, saline (SF) was administered to the control and BDL groups for 28 days while 250 mg/ kg of Cuscuta sp. extract was given by oral gavage to the CUS and BDL + CUS groups. At the end of the experiment, cognitive eval- uations were made by applying new object recognition and Morris water maze tests. After these tests, blood-brain barrier (BBB) measurements were made in half of the groups. In the other half of the groups, brain tissue samples were taken by decapitation and transforming growth factor-beta (TGF-β), 8-hydroxydeoxyguanosine (8-OHdG) and sodium-potassium adenosine triphospha- tase (Na+/K+-ATPase) measurements were made in the tissues. Histological examinations of the tissues were also performed. RESULTS: Cognitive performance was low, and BBB permeability was found to be increased in the group with bile duct liga- tion. In addition, TGF-β and 8-OHdG levels were increased in tissues, while Na+/K+-ATPase enzyme activity was suppressed. Treatment with Cuscuta sp. increased cognitive performance and decreased BBB permeability. Other biochemical parameters examined were significantly (p<0.05–0.001) reversed and supported by histological findings. CONCLUSION: Our findings in the study suggest that dodder plant may be beneficial for the protection of cognitive perfor- mance and brain tissue in encephalopathy caused by cholestasis. Keywords: Cuscuta sp.; cholestasis; encephalopathy; fibrosis.

(Ios Press, 2024) Degerli, Medine Nur Ozata; Aydoner, Selen; Altuntas, Onur; Bumin, Gonca
BACKGROUND: The coronavirus outbreak (COVID-19) has caused various effects, changing people's lives and work styles. During this period, workplaces decided to work remotely, so people spent more time at home. Therefore, workers' personal and work lives were negatively affected. OBJECTIVE: This study planned to compare traditional and remote office workers' occupational balance and life satisfaction in Turkey during COVID-19. METHODS: Google Survey was used for data collection. Three hundred office workers (18-65 years old) from Turkey participated in the study. The occupational balance and life satisfaction levels of participants were assessed using the Occupational Balance Questionnaire (QB-Quest) and Personal Well-being Index-Adult (PWI-A). RESULTS: Data collected were analyzed statistically by the Independent Sample t-test. It was found that the remote office workers had lower levels of occupational balance (p = 0.02; r = -3.317) and life satisfaction (p = 0.01; r = -2.199) compared to the traditional office workers. CONCLUSION: Remote office workers were found to have lower occupational balance and life satisfaction than traditional office workers. In this period, when the way of working changes like COVID-19, it is crucial to determine office workers' occupational balance and life satisfaction and take precautions for their job performance and satisfaction.

Dual-Phase Malicious User Detection Scheme for IM-OFDMA Systems Using IQ Imbalance
(Wiley, 2025) Alaca, Ozgur; Althunibat, Saud; Riza Ekti, Ali; Yarkan, Serhan; Miller, Scott L.; Qaraqe, Khalid A.
Physical-layer security techniques have contributed to the achievement of various security objectives in an efficient and lightweight manner. Thus, these techniques have been widely considered for limited-resource networks such as Internet of Things networks. Among the different security objectives, malicious user detection by exploiting physical-layer parameters has demonstrated efficient performance. In this work, malicious user detection in the recently proposed index modulation-based orthogonal frequency division multiple access (IM-OFDMA) is addressed. The proposed malicious user detection scheme exploits the hardware impairments, especially the in-phase and quadrature imbalance parameters, for both legitimate and malicious users to design a dual-phase efficient detection scheme. The proposed scheme accounts for the special characteristics of IM-OFDMA transmission that are different from other multiple-access techniques. The performance of the proposed scheme was evaluated considering detection probability and false alarm probability performance metrics. Moreover, closed-form expressions of these metrics were derived for both phases and were validated by Monte Carlo simulation results under different configurations of IM-OFDMA systems.

Background: This research aims to compare e-health literacy of technology users and nonusers in people with multiple sclerosis (MS) and to investigate whether there are correlations between age, duration of MS, gender, marital status, and e-health total scores.Methods: This descriptive study was carried out with a web-based questionnaire. The questionnaire was sent to 300 patients with MS who were registered at Istanbul University-Cerrahpasa Medical Faculty Neurology Department.Results: A total of 156 people (mean age: 35.33 +/- 10.47 years) participated in the survey. Smartphone 98.1% (n = 153) was the mostly used device. Rate of using Google and recommended websites about MS was 94.25% (n = 145) and 73.9% (n = 113), respectively. e-Health literacy of both the tablet and recommended websites users significantly differed from that of nonusers (p = 0.007 for both). Participants' e-health literacy total score was found to weakly, but significantly, correlate with their age, marital status, and education level (rho: -0.161, p = 0.044; rho: 0.172, p = 0.032; rho: -0.192, p = 0.016, respectively).Conclusions: With developments in digital technologies, it is important to identify the access status of people with MS to improve daily clinical management and implement further motor and cognitive rehabilitation. Therefore, determining the health literacy of individuals with MS and providing education on this subject will reduce the information pollution.
