- Background: Current evidence shows inequality in the outcomes of rural and urban patients treated at their place of residence. This study compared in-hospital mortality between rural and urban patients with acute coronary syndrome (ACS) to find whether there were differences in the outcome and received treatment.Methods: Between May 2007 and January 2018, patients admitted with ACS were included. The patients’ demographic, clinical, and laboratory data, as well as their in-hospital medical courses, were recorded. The association between place of residence (rural/urban) and in-hospital mortality due to ACS was evaluated using logistic regression adjusted for potential confounders.Results: Of 9088 recruited patients (mean age =61.30±12.25 y; 5557 men [61.1%]), 838 were rural residents. A positive family history of coronary artery disease (P=0.003), smoking (P=0.002), and hyperlipidemia (P=0.026), as well as a higher body mass index (P=0.013), was seen more frequently in the urban patients, while the rural patients had lower education levels (P<0.001) and higher unemployment rates (P=0.009). In-hospital mortality occurred in 135 patients (1.5%): 10 rural (1.2%) and 125 urban (1.5%) patients (P=0.465). The Firth regression model, used to adjust the effects of possible confounders, showed no significant difference concerning in-hospital mortality between the rural and urban patients (OR, 1.57; 95% CI, 0.376 to 7.450; P=0.585).Conclusion: This study found no significant differences in receiving proper treatment and in-hospital mortality between rural and urban patients with ACS.

- Background: Socioeconomic status (SES) can greatly affect the clinical outcome of medical problems. We sought to assess the in‑hospital mortality of patients with the acute coronarysyndrome (ACS) according to their SES.Methods: All patients admitted to Tehran Heart Center due to 1st‑time ACS between March 2004 and August 2011 were assessed. The patients who were illiterate/lowly educated (≤5 years attained education) and were unemployed were considered low‑SES patients and those who were employed and had high educational levels (>5 years attained education) were regarded as high‑SES patients. Demographic, clinical, paraclinical, and in‑hospital medical progress data were recorded. Death during the course of hospitalization was considered the end point, and the impact of SES on in‑hospital mortality was evaluated.Results: A total of 6246 hospitalized patients (3290 low SES and 2956 high SES) were included (mean age = 60.3 ± 12.1 years, male = 2772 [44.4%]). Among them, 79 (1.26%) patients died. Univariable analysis showed a significantly higher mortality rate in the low‑SES group (1.9% vs. 0.6%; P < 0.001). After adjustment for possible cofounders, SES still showed a significant effect on the in‑hospital mortality of the ACS patients in that the high‑SES patients had a lower in‑hospital mortality rate (odds ratio: 0.304, 95% confidence interval: 0.094–0.980; P = 0.046).Conclusions: This study found that patients with low SES were at a higher risk of in‑hospital mortality due to the ACS. Furthermore, the results suggest the need for increased availability of jobs as well as improved levels of education as preventive measures to curb the unfolding deaths owing to coronary artery syndrome.

- Objective:Sedentary behavior in children is positively associated with an increased risk of both obesity and insulin resistance. Children spend a considerable portion of their awake time in sedentary behavior; however, the pattern of accumulation is not known. Thus the objective of this study was to describe the patterning of sedentary behavior of children at and away from school.Design and Methods:The patterns of sedentary time in a sample of 53 children (28 girls) aged 10-12 years during school-term time were examined. Children wore an accelerometer for 1 week. Total sedentary time, prolonged sequences (bouts) of sedentary time, and frequency of active interruptions to sedentary were examined on school days and weekends and within school time and non-school time on school days.Results:The data did not support our hypothesis that children accumulated more sedentary time on school days when compared with weekend days (mean [SD]: 64.4% [5.3] vs. 64.9% [9.0], P = 0.686). However, when comparing school time with non-school time on school days, children accumulated more sedentary time at school (66.8% [7.3] vs. 62.4% [5.2], P < 0.001) and spent more time at school in sustained sedentary sequences, that is, uninterrupted sedentary time for 30 min or more (75.6 min [45.8] vs. 45.0 min [26.8], P < 0.002). The children also recorded less breaks per sedentary hour within school time when compared with non-school time (8.9 h−1 vs. 10.2 h−1, P < 0.001).Conclusion:Reducing total sedentary time spent both in and out of school remains an important challenge. Interrupting sedentary time more often in the “working” (school) day could also reap important musculoskeletal and metabolic health rewards for children.

- Ontologies have been proposed as a means towards making data FAIR (Findable, Accessible, Interoperable, Reusable). This has attracted much interest in several communities and ontologies are being developed. However, to obtain good results when using ontologies in semantically-enabled applications, the ontologies need to be of high quality. One of the quality aspects is that the ontologies should be as complete as possible. In this paper we propose a first version of a tool that supports users in extending ontologies using a phrase-based approach. To demonstrate the usefulness of our proposed tool, we exemplify the use by extending the Materials Design Ontology.

- Due to importance of data FAIRness (Findable, Accessible, Interoperable, Reusable), ontologies as a means to make data FAIR have attracted more and more attention in different communities and are being used in semantically-enabled applications. However, to obtain good results while using ontologies in these applications, high quality ontologies are needed of which completeness is one of the important aspects. An ontology lacking information can lead to missing results. In this paper we present a tool, Phrase2Onto, that supports users in extending ontologies to make the ontologies more complete. It is particularly suited for ontology extension using a phrase-based topic model approach, but the tool can support any extension approach where a user needs to make decisions regarding the appropriateness of using phrases to define new concepts. We describe the functionality of the tool and a user study using Pizza Ontology. The user study showed a good usability of the system and high task completion. Further, we report on a real application where we extend the Materials Design Ontology.

- Aim To study the leadership and management skills of first-line managers (FLMs) of elderly care and their work environment in Egypt and Sweden. Background FLMs in Egypt and Sweden are directly responsible for staff and quality of care. However, FLMs in Sweden, in elderly care, have smaller units/organizations to manage than do their colleagues in Egypt. Furthermore, family care of the elderly has been the norm in Egypt, but in recent years institutional care has increased, whereas in Sweden, residential living homes have existed for a longer period. Methods A convenience sample of FLMs, 49 from Egypt and 49 from Sweden, answered a questionnaire measuring leadership and management skills, structural and psychological empowerment, job satisfaction and psychosomatic health. Results In both countries, FLMs' perceptions of their leadership and management skills and psychological empowerment were quite high, whereas scores for job satisfaction and psychosomatic health were lower. FLMs had higher values in several factors/study variables in Egypt compared with in Sweden. Conclusion and implications The work environment, both in Egypt and Sweden, needs to be improved to increase FLMs' job satisfaction and decrease stress. The cultural differences and levels of management have an effect on the differences between the two countries.

TE-Polarized Electromagnetic Wave Diffraction by a Circular Slotted Cylinder
- 2023
-
Ingår i: Mathematics. - : MDPI. - 2227-7390. ; 11:9

Tidskriftsartikel (refereegranskat)abstract
- The problem of diffraction of a TE-polarized electromagnetic wave by a circular slotted cylinder is investigated. The boundary value problem in question for the Helmholtz equation is reduced to an infinite system of linear algebraic equations of the second kind (SLAE-II) using integral summation identities (ISI). A detailed study of the matrix operator of the problem is performed and its Fredholm property in the weighted Hilbert space of infinite sequences is proven. The convergence of the truncation method constructed in the paper for the numerical solution of SLAE-II is justified and the results of computations are presented and discussed, specifically considering the determination of resonance modes.

- Human–computer interface was utilized to amplify the power of a hybrid algorithm that combines fuzzy logic, regression analysis, and non-linear optimization to extract knowledge from a roll pass design database. This strategy is applied to grooves with vertical and horizontal symmetry which are employed in initial passes to roll a broad range of steel products. The results presented here from the case study are both statistically significant and valid from the viewpoint of roll pass design theory. © 2015, Springer-Verlag London.
