attitudes on TQM implementation and job satisfaction in public health sector
Authors: Škarica Ivana , Vrtodušić Hrgović Ana-Marija
Published: May 2021

The quality of service in the public health sector is an essential aspect that influences patient satisfaction. Providing quality in public
health sector means delivering health service in an affordable, safe and effective manner, with minimal risk and harm for patients. In other words, it means fulfilling patients’ needs and surpassing their expectations. In order to provide patients with good-quality and satisfactory service, many public health organizations implement quality
standards that contribute with many benefits and advantages, among which employee satisfaction stands out. The objective of the research was to evaluate the attitude of employees in public health institutes towards the dimensions of job satisfaction and their perception of the level of TQM implementation, with regard to the employees’ sociodemographic characteristics. In order to achieve this objective, ANOVA was used to test the hypotheses and determine the difference between observed sociodemographic characteristics with regard to the dimensions of job satisfaction and the application of TQM principles in research. Beside that, correlation coefficient was used to test the connection between overall job satisfaction and the level of TQM implementation (overall TQM principles). The findings suggest that level
of education and the length of service have a significant effect on the
differences in assessments among employees, while position in the workplace affects within certain dimensions of job satisfaction, as well
as within their perception of the TQM implementation. Results have also
shown that there is a statistically significant relationship between job satisfaction and the level of implementation of TQM principles. The present study provides valuable guidelines for public health sector managers since the results of the research indicate the level of perception of the implementation of TQM principles and job satisfaction dimensions with which employees are the most and the least satisfied, thus pointing out to management in public health sector institutions the
areas in which certain improvement measures should be implemented. As this study focuses specifically on Institutes of Public Health, future research could be expanded to encompass other public health institutions
such as hospitals and private clinics as well as other sectors.

Trong bài báo này, hai mẫu kết cấu sàn liên hợp thép-bê tông sơ đồ dầm đơn giản với tỷ lệ 1:1 có các kích thước thực tế 2800 × 615 × 145 mm được chế tạo trong phòng thí nghiệm và tiến hành thí nghiệm uốn bốn điểm để đánh giá sự làm việc theo trạng thái giới hạn cực hạn và trạng thái giới hạn sử dụng. Thí nghiệm được thực hiện theo tiêu chuẩn EN 1994-1-1:2004. Kết quả thí nghiệm cho thấy giá trị tải trọng thí nghiệm trung bình tương ứng với độ võng cho phép 13,5 mm là 28,74 kN. Giá trị này bằng 85,2% so với kết quả xác định theo lý thuyết (33,73 kN) và bằng 63,0% so với tải trọng thí nghiệm trung bình cực hạn gây phá hoại mẫu (45,59 kN). Khi tải trọng thí nghiệm đạt đến 25 kN, sự trượt dọc giữa bê tông với tôn sóng được ghi nhận và tăng nhanh đến 3 mm. Sau khi xảy ra hiện tượng trượt dọc giữa bê tông với tôn sóng, tải trọng và độ võng cũng đồng thời tăng cho đến khi sàn bị phá hoại. Điều này đồng nghĩa với việc ứng xử của sàn là phá hoại dẻo

Published: May 2021

The use of MKJP in Indonesia has decreased every year from 13.7% in 1991 to 10.6% in 2012 (Ministry of Health, 2013). In 2013, based on a mini survey of the Population and Family Planning Agency (BKKBN), the coverage of MKJP in Indonesia was only 12.4% with a percentage based on the type of method, namely KB implants (5.2%), IUD (Contraceptive Devices in the Womb) / Intrauterine Device (IUD) (4.7%), and Women's Operations Method (MOW) (2.2%), whereas the expected MKJP target is 26.7%. This research is descriptive analytic, conducted to determine factors related to the interest in using MKJP (IUD Implants) in Perigi Mekar Village in 2016. The number of samples in this study were 104 people. Data were collected using a questionnaire. Of the 9 variables studied, 2 variables showed a significant relationship with the interest in using the MKJP is income with a p value of 0.018, and discussions with a partner with a p value of 0.024. From the above statement it can be concluded that the amount of income and the frequency of discussions with partners influences the interest in using the MKJP. It is expected that community leaders can work together with local health workers so that they can provide counseling to the community regarding long-term contraceptive methods. Keyword : Contraception, MKJP, IUD, Implant

Myasthenia gravis is an autoimmune neuromuscular disease with a multifactorial etiology. A major part of the genetic susceptibility belongs to the HLA encoding genes. In this study, we investigated the role of HLA class II polymorphism in disease severity, and treatment response. In our 146 patients, 15 DRB1, 7 DQA1, and 9 DQB1 alleles, and 19 haplotypes were found. Adjusted p-values did not show any significant associations between these loci, disease severity and treatment outcome. Further studies in different populations with a larger number of patients are needed to determine the exact contribution of HLA class II alleles to MG prognosis.

Authors: Mishchenko Vladimir I. , Kravtsov Alexander N. , Mamleev Timur F.
Published: May 2021

The problem of modeling the process of functioning of redundant measuring instruments is considered. On the basis of the developed model, the determination of the frequency of verification of complex duplicated measuring instruments based on the semi-Markov model of the process of their functioning is justified. The relevance of the application of the theory of semi-Markov processes for modeling the functioning of redundant technical systems, including measuring instruments, is shown. A semi-Markov model of the process of functioning of measuring instruments has been developed, which allows us to take into account the influence of the frequency of verification, the provision of measuring instruments with spare elements, as well as the level of reliability and maintainability on the reliability of measuring instruments. A method is found for defining a semi-Markov process that correctly and adequately approximates the real process. The indicator of the effectiveness of the functioning of the measuring instruments and the corresponding model is the availability factor of the measuring instruments.

Electronic and electrical wastes (EEW) have increased exponentially in recent years due to technological progress. The uncontrolled incineration of these wastes causes pollution of air, soil, and water that has dangerous effects on health of human beings and other living organisms. This work isolated fungi that are capable of degrading some of these electronic wastes. In this study, fungi isolated from soil polluted by EEW were grown on potatoes dextrose agar (PDA) medium. The estimation of the biodegradation was achieved by inoculation of both rechargeable batteries and printed circuit boards on a minimum solid and liquid medium with selected fungal strains. During the process of biodegradation on solid medium, microscopic observation was done, and on liquid medium the production of keratinolytic enzymes was evaluated using a colorimetric method after incubation with keratine powder. After 30 days, the obtained results showed that Geotrichum candidum is capable of degrading battery and circuit boards with rates of 23% and 71%, respectively, while Rhizopus stolonifer reduced battery weight by 7% and printed circuit boards by 60%. Microscopic observations showed no morphological modification in Geotrichum candidum, while there was sporocyst formation in Rhizopus stolonifer. The detection of enzymatic production indicated that there is a relation between the biodegradation process of electronic wastes and keratinolytic enzymes in Geotrichum candidum.

Imaginarios y narrativas cinematográficas sobre el fin del mundo
Authors: Brito-Alvarado Leonardo Xavier , Guamán Guadalima Nelly , Capito Alvarez Paola
Published: May 2021

El cine de ficción ha reflexionado sobre el fin del mundo desde diversas miradas: invasión alienígena, desastres naturales, pandemias, la llegada de objetos del espacio exterior, entre otros. Cualquiera que sea la amenaza, existe un patrón común, la salvación de la humanidad se debe a la intervención de Occidente. Este ensayo debate los imaginarios y narrativas del cine de ficción desde una mirada antropológica, comunicacional y sociológica que asume las siguientes premisas: (a) las situaciones siempre parten de posibles supuestos y (b) las ideologías expuestas son invisibilizadas por el despliegue audiovisual de efectos especiales. Metodológicamente, se ha procedido al análisis de películas producidas en Hollywood de 1990 a 2019. El criterio de selección está determinado de acuerdo con el tipo de amenazas (objetos espaciales, virus, cambios climáticos, alienígenas) y las taquillas alanzadas por las películas.

Published: May 2021

In improving the quality of school education and learning in the future, it is necessary to change the mindset that will be used as the basis for implementing a learning program. What's more in the co-19 pandemic period that requires students to be able to study at home without interacting in class for a while. In the past the learning process was conventional, namely face-to-face in class. But even then, most teaching processes are still dominated by teachers. As a result, teaching and learning activities place more emphasis on teaching and not on learning. Learning activities favor the interests of those who teach. Efforts for learning to be focused on students, it is necessary to apply a cooperative learning model which is a form of change in mindset in learning activities at school. However, during this pandemic, the next challenge is how the cooperative process can take place in the online learning process. The absence of a physical meetup becomes an obstacle that can be minimized by the adaptation of the teacher in the distance learning process. In this case the teacher no longer dominates the learning activities, but rather becomes the facilitator and mediator of the process. The cooperative learning model is designed by giving opportunities to students together to build their own knowledge.

Authors: Nur Ayesha Najma , Bhowmik Juthi , Chowdhury Shiuly , Begum Shirin Akter
Published: May 2021

Background: The uterine cervix is the commonest site for female genital cancer. In developing countries, carcinoma cervix is the most common malignancy in females and a major public health problem. It is reported In Bangladesh that the prevalence of carcinoma cervix is 20% among all types of cancer affecting females. To determine the level of knowledge, attitude and practice among Bangladeshi women about screening of cervical carcinoma

Materials and methods: A cross-sectional study was conducted on married women above the age of 20 years, attending OPD of Obstetrics & Gynecology, Medicine and Surgery of BSMMU from January 2013 to June 2013. By using purposive sampling technique 225 respondents were enrolled in the study.

Results: Mean age of the respondents was 43.34 years with a standard deviation of ± 12.49 years. Most of the respondents (96%) were Muslim and from urban areas. More than two-thirds of the respondents (71.1%) were educated up to secondary level. More than 80% respondents were housewives. About three-fourth of the respondents were form middle class families. Only 20% could mention cervical cancer as the leading cancer among women. About 20% respondents knew that early and multiple marriages were the two risk factors for cervical cancer. Most of the respondents (93.3%) believed that cervical cancer is dangerous disease and was able to mention smoking as one of the important risk factors. About one-third respondents knew that terms Pap’s smear and VIA. But most of the respondents did not undergo any screening procedure under the assumption that the screening was not necessary. It was found that respondents with higher education level possessed good knowledge regarding cervical cancer. It was also true for respondents whose husbands were more educated. Higher education level was positively correlated with good attitude/practices. The respondents who had good knowledge about cervical cancer showed good attitude/practice regarding the same.

Conclusion: The knowledge regarding cervical cancer among the participants was not satisfactory. Although most of the participants believed that cervical cancer is dangerous disease few really knew that it is preventable. Higher education level was positively correlated with good knowledge and good attitude/practices regarding cervical cancer. Long term education for women should be started to provide the needed information regarding cervical cancer screening.

Preoperative Radiological Parameters to Predict Clinical and Radiological Outcomes after Laminoplasty
Authors: Lee Su Hun , Son Dong Wuk , Shin Jun Jae , Ha Yoon , Song Geun Sung , Lee Jun Seok , Lee Sang Weon
Published: May 2021

Many studies have focused on pre-operative sagittal alignment parameters which could predict poor clinical or radiological outcomes after laminoplasty. However, the influx of too many new factors causes confusion. This study reviewed sagittal alignment parameters, predictive of clinical or radiological outcomes, in the literature. Preoperative kyphotic alignment was initially proposed as a predictor of clinical outcomes. The clinical significance of the K-line and K-line variants also has been studied. Sagittal vertical axis, T1 slope (T1s), T1s-cervical lordosis (CL), anterolisthesis, local kyphosis, the longitudinal distance index, and range of motion were proposed to have relationships with clinical outcomes. The relationship between loss of cervical lordosis (LCL) and T1s has been widely studied, but controversy remains. Extension function, the ratio of CL to T1s (CL/T1s), and Sharma classification were recently proposed as LCL predictors. In predicting postoperative kyphosis, T1s cannot predict postoperative kyphosis, but a low CL/T1s ratio was associated with postoperative kyphosis.

Objective : Through our previous clinical trials, the demonstrated therapeutic effects of MSC in chronic spinal cord injury (SCI) were found to be not sufficient. Therefore, the need to develop stem cell agent with enhanced efficacy is increased. We transplanted enhanced Wnt3asecreting human mesenchymal stem cells (hMSC) into injured spines at 6 weeks after SCI to improve axonal regeneration in a rat model of chronic SCI. We hypothesized that enhanced Wnt3a protein expression could augment neuro-regeneration after SCI.Methods : Thirty-six Sprague-Dawley rats were injured using an Infinite Horizon (IH) impactor at the T9–10 vertebrae and separated into five groups : 1) phosphate-buffered saline injection (injury only group, n=7); 2) hMSC transplantation (MSC, n=7); 3) hMSC transfected with pLenti vector (without Wnt3a gene) transplantation (pLenti-MSC, n=7); 4) hMSC transfected with Wnt3a gene transplantation (Wnt3a-MSC, n=7); and 5) hMSC transfected with enhanced Wnt3a gene (1.7 fold Wnt3a mRNA expression) transplantation (1.7 Wnt3a-MSC, n=8). Six weeks after SCI, each 5×105 cells/15 µL at 2 points were injected using stereotactic and microsyringe pump. To evaluate functional recovery from SCI, rats underwent Basso-Beattie-Bresnahan (BBB) locomotor test on the first, second, and third days post-injury and then weekly for 14 weeks. Axonal regeneration was assessed using growth-associated protein 43 (GAP43), microtubule-associated protein 2 (MAP2), and neurofilament (NF) immunostaining.Results : Fourteen weeks after injury (8 weeks after transplantation), BBB score of the 1.7 Wnt3a-MSC group (15.0±0.28) was significantly higher than that of the injury only (10.0±0.48), MSC (12.57±0.48), pLenti-MSC (12.42±0.48), and Wnt3a-MSC (13.71±0.61) groups (p<0.05). Immunostaining revealed increased expression of axonal regeneration markers GAP43, MAP2, and NF in the Wnt3a-MSC and 1.7 Wnt3a-MSC groups.Conclusion : Our results showed that enhanced gene expression of Wnt3a in hMSC can potentiate axonal regeneration and improve functional recovery in a rat model of chronic SCI.

This study is aimed to develop the anxiety scale toward novel corona virus in Turkish public. The online questionnaire surveyed 1075 individuals from the general population of 70 provinces of Turkey who completed the questionnaire via social networks from May 1 to June 15, 2020. Two different samples were used in this study. In first step, 415 data were collected in second step 649 data was obtained for confirmatory factor analysis. A series of exploratory factor analyses were conducted on data obtained from the first sample. As a result of the exploratory factor analysis, 9 items were removed from the scale consisting of 17 items. The final COVID-19 Anxiety Scale consisting of two factors, which are Overreaction and Overprotection- Hygiene, and eight items, have been found as capable to measure the anxiety towards COVID-19. The construct validity of the COVID-19 Anxiety Scale, revealed by exploratory factor analysis, was tested with the confirmatory factor analysis applied to the second sample data. Accordingly, it has been revealed that the two-factor construct of the COVID-19 Anxiety Scale ensures a perfectly model-data fit. Another validity study is the determination of measurement invariance in gender groups of the Covid-19 Anxiety Scale. The results show that metric invariance was provided. Thus, factor variances and structural relationships between groups are comparable. The convergent validity of the scale was examined through item loadings, composite reliability, and average variance extracted values. All of them provide critical values for convergent validity. Since the correlation between the factors was lower than the average variance extracted by the factors, the discriminate validity of the scale was also provided. The reliability of the scale was examined with Cronbach's alpha and composite reliability. Both reliability coefficients show that the COVID-19 Anxiety Scale is reliable at a good level.
Slavic languages in contact: Turkish -ı- > Serbian, Croatian -r-
Authors: Stachowski Marek
Published: May 2021

Even though there is no sonantic r̥ in Turkish, some Croatian and Serbian reflexes of Turkish loanwords display an r̥. Such examples form two typologically different groups. One of them can be explained by a purely Slavic phonological proportion. The other group, however, can only be characterised in terms of Turkish phonetics, but its full explanation escapes our analyses.
Explaining Code-Switching. Matrix Language Models vs. Bilingual Construction Grammar
Authors: Wasserscheidt Philipp
Published: May 2021

This paper challenges the concept of matrix, base or basic language used in many descriptions and models of insertional code-switching. It proposes an account based on Construction Grammar and usage-based principles. At the heart of the paper is a discussion of four problematic issues of matrix-language approaches: the unitary conception of the notion of language, the generalization that syntactic frames mirror languages, the missing independent evidence for a matrix language and the narrow scope of the models that employ this term. The proposed approach of Bilingual Construction Grammar instead operates with a more complex, usage-based concept of language affiliation and places constructions in the centre of speech production. It thus avoids too coarse global predictions in favour of construction-specific predictions. This way, the matrix-language effect can be reinterpreted as by-product of constructional processing. Instead of using the term matrix language it is thus more appropriate to speak of matrix constructions.

50 Years of Pollen Monitoring in Basel (Switzerland) Demonstrate the Influence of Climate Change on Airborne Pollen
Authors: Gehrig Regula , Clot Bernard
Published: May 2021

Climate change and human impact on vegetation modify the timing and the intensity of the pollen season. The 50 years of pollen monitoring in Basel, Switzerland provide a unique opportunity to study long-term changes in pollen data. Since 1969, pollen monitoring has been carried out in Basel with a Hirst-type pollen trap. Pollen season parameters for start dates, end dates and duration were calculated with different pollen season definitions, which are commonly used in aerobiology. Intensity was analyzed by the annual pollen integral (APIn), peak value and the number of days above specific thresholds. Linear trends were calculated with the non-parametric Mann Kendall method with a Theil-Sen linear trend slope. During the last 50 years, linear increase of the monthly mean temperatures in Basel was 0.95–1.95°C in the 3 winter months, 2–3.7°C in spring months and 2.75–3.85°C in summer months. Due to this temperature increase, the start dates of the pollen season for most of the spring pollen species have advanced, from 7 days for Poaceae to 29 days for Taxus/Cupressaceae. End dates of the pollen season depend on the chosen pollen season definition. Negative trends predominate, i.e., the pollen season mostly ends earlier. Trends in the length of the pollen season depend even more on the season definitions and results are contradictory and often not significant. The intensity of the pollen season of almost all tree pollen taxa increased significantly, while the Poaceae pollen season did not change and the pollen season of herbs decreased, except for Urticaceae pollen. Climate change has a particular impact on the pollen season, but the definitions used for the pollen season parameters are crucial for the calculation of the trends. The most stable results were achieved with threshold definitions that indicate regular occurrence above certain concentrations. Percentage definitions are not recommended for trend studies when the annual pollen integral changed significantly.
Simulation of Nonstationary and Nonhomogeneous Wind Velocity Field by Using Frequency–Wavenumber Spectrum
Authors: Hong P. , Hong H. P.
Published: May 2021

The time history analysis is used to estimate the peak responses of structures subjected to stationary and nonstationary winds. The time histories of the fluctuating wind processes at multiple points can be simulated based on the spectral representation method for given target auto and cross power spectral density (PSD) functions. As the number of the processes of interest increases, the computation time for the simulation increases drastically. For the stationary homogeneous or nonhomogeneous wind fields, this problem can be overcome by using the frequency-wavenumber PSD function to simulate the stochastic propagating waves or fields. In the present study, a technique to simulate the amplitude modulated and frequency modulated nonstationary and nonhomogeneous stochastic propagating wind fields is presented. The technique relies on representing the nonstationary wind velocity by amplitude modulating a process that is time transformed from a stationary process. It is based on the established relations between the PSD functions of the nonstationary and of the stationary wind velocity. Simple to use and implement equations to carry out the simulation for one-dimensional line wind velocity field and two-dimensional nonstationary and nonhomogeneous wind velocity field are presented. The use of the developed technique and its adequacy is illustrated through numerical examples.

Dental stem cells (DSCs) holds the ability to differentiate into numerous cell types. This property makes these cells particularly appropriate for therapeutic use in regenerative medicine. We report evidence that when DSCs undergo osteogenic differentiation, the osteoblast-like cells can be reverted back to a stem-like state and then further differentiated toward the osteogenic phenotype again, without gene manipulation. We have investigated two different MSCs types, both from dental tissues: dental follicle progenitor stem cells (DFPCs) and dental pulp stem cells (DPSCs). After osteogenic differentiation, both DFPCs and DPSCs can be reverted to a naïve stem cell-like status; importantly, dedifferentiated DSCs showed a greater potential to further differentiate toward the osteogenic phenotype. Our report aims to demonstrate for the first time that it is possible, under physiological conditions, to control the dedifferentiation of DSCs and that the rerouting of cell fate could potentially be used to enhance their osteogenic therapeutic potential. Significantly, this study first validates the use of dedifferentiated DSCs as an alternative source for bone tissue engineering.

Background

CD8+ T cells work as a key effector of adaptive immunity and are closely associated with immune response for killing tumor cells. It is crucial to understand the role of tumor-infiltrating CD8+ T cells in uveal melanoma (UM) to predict the prognosis and response to immunotherapy.

Materials and Methods

Single-cell transcriptomes of UM with immune-related genes were combined to screen the CD8+ T-cell-associated immune-related genes (CDIRGs) for subsequent analysis. Next, a prognostic gene signature referred to tumor-infiltrating CD8+ T cells was constructed and validated in several UM bulk RNA sequencing datasets. The risk score of UM patients was calculated and classified into high- or low-risk subgroup. The prognostic value of risk score was estimated by using multivariate Cox analysis and Kaplan–Meier survival analysis. Moreover, the potential ability of gene signature for predicting immunotherapy response was further explored.

Results

In total, 202 CDIRGs were screened out from the single-cell RNA sequencing of GSE139829. Next, a gene signature containing three CDIRGs (IFNGR1, ANXA6, and TANK) was identified, which was considered as an independent prognostic indicator to robustly predict overall survival (OS) and metastasis-free survival (MFS) of UM. In addition, the UM patients were classified into high- and low-risk subgroups with different clinical characteristics, distinct CD8+ T-cell immune infiltration, and immunotherapy response. Gene set enrichment analysis (GSEA) showed that immune pathways such as allograft rejection, inflammatory response, interferon alpha and gamma response, and antigen processing and presentation were all positively activated in low-risk phenotype.

Conclusion

Our work gives an inspiration to explain the limited response for the current immune checkpoint inhibitors to UM. Besides, we constructed a novel gene signature to predict prognosis and immunotherapy responses, which may be regarded as a promising therapeutic target.
