Authors: Ramezani Amirhossein , Parastouei Karim , Delkhosh Marjan , Rostami Hossein
Published: June 2021

Background:Military forces can be considered in the group of active people or athletes due to their high activity and exercises. The aim of this study was to determine the relationship between dietary inflammatory index (DII) with physical function and anthropometric indices in the marine.Methods:This cross-sectional study was performed on 200 male aged 18 to 45 years in the Navy. Individual data were collected using a general questionnaire, exercise tests and anthropometric assessments. Food intake over the past year was assessed using a 147-item semi-quantitative food frequency questionnaire, and then the DII score was calculated for each subject. Aerobic performance was assessed using the 12 minutes cooper test. Also, the repetitions of sit up, pull up and push up in 1 minute were recorded to assess physical strength. Linear regression was used to investigate the relationship between DII with anthropometric indices and athletic performance.Results:The present study showed that the increase in DII is directly related to body mass index (P = 0.04) and body fat percentage (P = 0.03), and inversely related to VO2max (P = 0.001). However, after adjusting for the effect of energy intake in regression model, only the association between DII and VO2max was statistically significant (β= -1.69, SE=0.67, P=0.01). Conclusion:In general, with the increase of dietary potential in causing inflammation, it may lead to an increase in BMI and body fat percentage and a decrease in aerobic capacity in military personnel. However, the observed relationship between DII and anthropometric indices seems to be influenced by the energy intake. Further well-designed studies with a prospective method are warranted to find a definitive result.
Probabilistic demand assessment of bridges considering the effect of corrosion and seismic loading over time
Authors: Tolentino Dante , Herrera Daniel , Flores Ricardo B.
Published: June 2021

This paper proposes an approach to calculate demand hazard curves considering the effect of both corrosion and seismic loadings over time. The corrosion is defined as the reduction of the cross-sectional area in the reinforced bars of concrete, induced by chloride ions. Three corrosion phases are considered: starting time of corrosion, cracking, and evolution time. Seismic loads are characterized as a stochastic Poisson process. Uncertainties related to the randomness of geometric properties, mechanical properties, and seismic loadings are considered. The approach is illustrated in a continuous bridge designed to comply with a drift of 0.002. The structure is located in Acapulco, Guerrero, Mexico. Fragility curves and demand hazard curves are obtained at 0, 45, 57, 75, 100, and 125 years, based on the global drift. The effect of both corrosion and seismic loadings over time increase the annual rate of demand up to 308% between 0 years (without damage) and 125 years after the bridge construction.
Are New Zealand podiatrists satisfied with mandatory continuing professional development?
Authors: Carroll Matthew , Brenton-Rule Angela , Jepson Hannah , Molyneux Prue
Published: June 2021

Background

New Zealand (NZ) registered podiatrists are required to participate in continuing professional development (CPD). This study investigated podiatrist’s perceptions and satisfaction surrounding mandatory CPD requirements following the implementation of a new CPD programme.
Methods

A cross-sectional study of NZ registered podiatrists was conducted between October 9th and December 9th, 2020. Data was collected using a web-based survey. The 39-item survey included questions to elicit participant characteristics, perceptions of CPD, difficulties undertaking CPD, and satisfaction with the new CPD programme. A mixed quantitative and qualitative methodology was used to report the survey findings.
Results

One hundred and thirty-four podiatrists completed the survey. Most respondents worked in private practice (n = 107, 80%), and were in full-time employment (n = 83, 62%), and had greater than 16 years of work experience (n = 73, 54%). Respondents agreed it was important to engage in CPD (n = 126, 94%) and reported that knowledge gained from CPD contributed to their daily work (n = 78, 58%). Forty-four percent (n = 58) reported difficulties keeping up to date with CPD. The main barriers to CPD participation reported were workload (n = 90, 67%) and lack of time (n = 84, 63%). Three categories (understanding the CPD programme; access to CPD; and time to complete CPD) were identified from the qualitative analysis to describe why it was difficult to meet CPD requirements.
Conclusion

Overall, NZ podiatrists value CPD and are satisfied with most aspects of the mandatory CPD programme. Facilitation of CPD activities that are flexible, relevant to practitioner’s scope of practice and conducted in the workplace environment may address barriers to CPD access.
Experimental Estimation of the Longitudinal Component of a Highly Focused Electromagnetic Field
Authors: Maluenda David , Aviñoá Marcos , Ahmadi Kavan , Martínez-Herrero Rosario , Carnicer Artur
Published: June 2021

The detection of the longitudinal component of a highly focused electromagnetic beam is not a simple task. Although in recent years several methods have been reported in the literature, this measure is still not routinely performed. This paper describes a method that allows us to estimate and visualize the longitudinal component of the field in a relatively simple way. First, we measure the transverse components of the focused field in several planes normal to the optical axis. Then, we determine the complex amplitude of the two transverse field components: the phase is obtained using a phase recovery algorithm, while the phase difference between the two components is determined from the Stokes parameters. Finally, the longitudinal component is estimated using the Gauss’s theorem. Experimental results show an excellent agreement with theoretical predictions.

Most current medical imaging Artificial Intelligence (AI) relies upon transfer learning using convolutional neural networks (CNNs) created using ImageNet, a large database of natural world images, including cats, dogs, and vehicles. Size, diversity, and similarity of the source data determine the success of the transfer learning on the target data. ImageNet is large and diverse, but there is a significant dissimilarity between its natural world images and medical images, leading Cheplygina to pose the question, “Why do we still use images of cats to help Artificial Intelligence interpret CAT scans?”. We present an equally large and diversified database, RadImageNet, consisting of 5 million annotated medical images consisting of CT, MRI, and ultrasound of musculoskeletal, neurologic, oncologic, gastrointestinal, endocrine, and pulmonary pathologies over 450,000 patients. The database is unprecedented in scale and breadth in the medical imaging field, constituting a more appropriate basis for medical imaging transfer learning applications. We found that RadImageNet transfer learning outperformed ImageNet in multiple independent applications, including improvements for bone age prediction from hand and wrist x-rays by 1.75 months (p<0.0001), pneumonia detection in ICU chest x-rays by 0.85% (p<0.0001), ACL tear detection on MRI by 10.72% (p<0.0001), SARS-CoV-2 detection on chest CT by 0.25% (p<0.0001) and hemorrhage detection on head CT by 0.13% (p<0.0001). The results indicate that our pre-trained models that are open-sourced on public domains will be a better starting point for transfer learning in radiologic imaging AI applications, including applications involving medical imaging modalities or anatomies not included in the RadImageNet database.
Impact of COVID-19 on brain and psychological health, its possible mechanisms, and coping strategies
Authors: Simnani Faizan Zarreen , Singh Dibyangshee , Choudhury Anmol , Akhtar Ansab
Published: June 2021

COVID-19 pandemic has been depicted to possess a robust association with psychological disorders. SARS-CoV-2 is the most recent virus of the coronavirus family and has the potential to bind angiotensin-converting enzyme (ACE) receptor. The receptor is majorly present peripherally, and up to some extent in the brain. Different psychological and neurodegenerative disorders can arise due to peripheral origin of destruction. These triggers could be inflammatory pathways releasing pro-inflammatory cytokines reaching the brain and causing neuroinflammation. In continuation with traditional viruses, SARS-CoV-2 too might lead to brain diseases like meningitis, encephalitis, etc. Besides, several peripheral hormonal changes like cortisol can influence the neurochemical alterations, thereby inflicting mood-related activities and psychological phenomenon. In this regard, health care workers, frontline line worriers, family and relatives of COVID-19 patients can be the secondary victims; however, patients with COVID-19 themselves remain the primary ones prone to neurological health problems. Several strategies like socialization, engagement, physical activity, etc. are well-opted measures to get relief from and check the psychiatric disturbances.

Целью исследования являлось изучение естественного лесовозобновления в условиях средней тайги таежной лесорастительной зоны РФ на основе массовых данных лесоустройства, в которых отражена информация о ходе естественного лесовозобновления. Поставленная задача была решена с помощью электронной повыдельной базы данных объекта исследования, включающая в себя информацию, необходимую для общей оценки подроста хозяйственно ценных пород. Оценка естественного лесовозобновления была проведена по шкале оценки возобновления. Из общей электронной базы были отобраны все выделы естественного происхождения в возрасте преобладающей породы основного яруса старше 4-го класса возраста, т. е. хвойные старше 80 лет и мягколиственные старше 40 лет. Общий объем выборки составил 6533 выдела площадью 16814,2 га. В целом на 32,7% площади таксационных выделов, наблюдается полное отсутствие подроста хозяйственно
ценных пород. Структура породного состава подроста характеризуется практически полным доминированием елового подроста. Оптимальные условия для естественного лесовозобновления ели создаются в черничниках (встречаемость 99,8%) и в кисличниках – встречаемость 98,4%. Максимальный процент подроста с оценкой хорошо по преобладающей на выделе древесной породе (35% от всех выделов с подростом) оказался в сосняках кисличного типа леса в свежих суборях.

The aim of the study was to study natural reforestation in the middle taiga of the taiga forest zone of the Russian Federation on the basis of mass forest management data, which reflects information about the progress of preliminary reforestation. The task was solved with the help of an electronic database of the research object, which includes the information necessary for the overall assessment of the undergrowth of economically valuable breeds. The assessment of natural reforestation was carried out on the basis of the renewal assessment scale. From the general electronic database of data, all natural-origin selections were selected at the age of the predominant breed of the main tier older than the 4th age class, i.e. coniferous over 80 years old and softleaved over 40 years old. The total sample size was 6,533 allotments with an area of 16,814. 2 hectares. In general, on 32.7% of the area of taxation allotments, there is a complete absence of undergrowth of economically valuable breeds. The structure of the breed composition of the undergrowth is characterized by almost complete dominance of spruce undergrowth. Optimal conditions for the natural reforestation of spruce are created in blueberry forests (99.8% occurrence) and in acid forests-98.4% occurrence. The maximum percentage of undergrowth with a rating of good for the wood species prevailing in the allotment (35% of all allotments with the adolescent) was found in the pine forests of the acidic forest type in fresh sub-forests.

CT-negative Subarachnoid Hemorrhage Caused by Telangiectasia: A Case Report
Authors: Zhang Xin , Mang Jing , Shi Xiaohua , Xu Lei , Xu Zhongxin
Published: June 2021

Introduction:

At present, the mechanism of telangiectasia is unknown, but some evidence
suggests that it may be related to genetic abnormalities. Telangiectasia may lead to bleeding
of multiple sites. CT-negative subarachnoid hemorrhage is rare, which is mostly related to hemorrhage
with a little amount of bleeding. CT-negative subarachnoid hemorrhage due to telangiectasia
has not been reported.

Case Report:

In this case report, the patient experienced severe headache with nausea, vomiting,
and blurred vision for 12 days, and had a history of hypertension. Physical examination revealed a
clear state of mind, normal speech, normal limb muscle strength, 2 transverse fingers of neck stiffness,
and negative bilateral Babinski signs. Brain CT, MRI, MRA, and MRV showed no obvious
abnormalities. SWI suggested the possibility of capillary dilation. The cerebrospinal fluid was pale
yellow in appearance after lumbar puncture.

Diagnosis:

The patient was diagnosed with subarachnoid hemorrhage (SAH) and capillary dilatation.

Interventions:

Therapeutic management of blood pressure and brain edema was started.

Conclusion:

Lumbar puncture should be performed when subarachnoid hemorrhage is clinically
suspected and CT is negative. While searching for the cause of subarachnoid hemorrhage, the presence
of telangiectasia should be ascertained.
The Hidden Danger of Environmental Chemicals during the “Windows of Susceptibility” in a Woman’s Life – How can we use Intermediate Biomarkers to Improve Breast Cancer Prevention?
Authors: Rygiel Katarzyna
Published: June 2021

Introduction:

It has been observed that many toxic environmental agents increase risk, accelerate development, or deteriorate the course of breast cancer (BC). In particular, endocrine-disrupting chemicals (EDC) are harmful to endocrine receptor actions and signaling in the breast tissue.

Usually, there is a long interval of time between the exposure to EDC and BC incidence, and this often represents a serious obstacle for effective BC prophylaxis. Notably, during certain periods of a woman’s life cycle, the BC risk is particularly elevated due to increased susceptibility to some EDC. These windows of susceptibility (WOS) include prenatal, puberty, pregnancy, and menopausal transition stages of a female’s life course.

Four WOS have been considered as the most vulnerable periods for BC since the mammary gland undergoes the main anatomical and physiological transformations at those intervals. This means that during specific WOS, the EDC from the environment can have the most dangerous impact on BC risk and possible BC development later in a woman’s life. However, most clinical BC studies related to toxic environmental exposures have not been connected to the specific WOS.

Therefore, the goal of this article is to briefly describe some important research results, focused on the links between EDC and BC, within four critical WOS. In addition, this mini-review outlines some useful biomarkers for further research and prophylaxis of BC and also for both the research community and the medical professionals.

Conclusion:

To bridge the gap in BC prevention, it is essential to recognize the links between EDC and BC within the critical WOS. Moreover, an integrative model of BC research, applying intermediate biomarkers, is necessary to determine the mechanisms of action of various EDC during critical periods in a woman’s lifespan. Hopefully, this will lead to progress in BC prevention.
Diagnostic Value of MicroRNA 21 in Endometrial Cancer and Benign Lesions and its Differential Expression with Clinicopathological Parameters
Authors: Bouziyane Amal , Lamsisi Maryame , Benaguida Hicham , Benhessou Mustapha , El Kerroumi Mohamed , Ennaji Moulay Mustapha
Published: June 2021

Background:

Endometrial cancer is one of the most common malignancies among women
worldwide. Although this cancer is often diagnosed at early stages, the need for biomarkers of
diagnosis remains a necessity to overcome conventional invasive procedures of diagnosis.

Objective:

In our study, we aim to investigate the diagnostic value of microRNA-21 in endometrial
cancer and its relation to clinicopathological features.

Methods:

We used RT-qPCR to measure the expression of microRNA-21 in 71 tumor tissues, 53
adjacent tissues, and 54 benign lesions.

Results:

Our results show that microRNA-21 is a potential biomarker for endometrial cancer with
an area under the receiver operating characteristic curve of 0.925 (95% CI = 0.863 - 0.964,
P<0.0001). The sensitivity was 84.51% (95% CI = 74.0 - 92.0) and specificity was 86.79% (95%
CI = 74.7 - 94.5). For discrimination between benign lesions and controls the AUC was 0,881 with
a sensitivity of 100% (95% CI = 93.4 - 100.0) and specificity of 66.04% (95% CI = 51.7 - 78.5),
and for discriminating benign lesions from tumors the AUC was 0,750 with a sensitivity of 54.93%
(95% CI = 42.7 - 66.8) and specificity of 90.74% (95% CI = 79.7 - 96.9). We also found that tumors
with elevated microRNA-21 expression are of advanced FIGO stage, high histological
grades, and have cervical invasion, myometrial invasion and distant metastasis.

Conclusion:

Our findings support the important role of miR-21 as a biomarker to diagnose endometrial
cancer. Further studies on minimally invasive/noninvasive samples such as serum,
blood, and urine are necessary to provide a better alternative to current diagnosis methods.
Establishment of histopathological diagnosis based on bladder cancer-specific microRNA and gene expression mechanism
Authors: Fujii Tomomi
Published: June 2021

Cancer treatment tends to be more effective if cancer is diagnosed early on. Improved means of identification and diagnosis are therefore crucial. As many existing methods of diagnosing cancers don't facilitate early diagnosis, a team of researchers in the Department of Diagnostic Pathology,
Nara Medical University, Japan, is developing improved methods of diagnosing cancers such as bladder cancer and prostate cancer. Associate Professor Tomomi Fujii and the team hope their work will lead to earlier diagnosis and more effective treatment, improving patient outcomes and the resources
available to healthcare professionals. The researchers are focused on the use of microRNA and gene expression mechanisms to heighten the effectiveness of histopathological diagnoses. The team believes that if it can understand more about the mechanisms associated with microRNAs and cancer,
this will assist in the development of improved diagnostic methods. In particular, Fujii and the team want to clarify the functions of target molecules of specific microRNAs and molecules expressed in conjunction with microRNAs and believe this could be key to developing advanced drug therapies
for cancer in the form of molecular-targeted therapies. When it comes to urinary tumours such as bladder cancer and prostate cancer, the researchers are interested in analysing microRNAs as a trigger through which they can search for important molecules in urinary tumours and potentially act
directly on the cancer to stop it from growing or to prevent it from metastasising to other organs.
Elucidation of the pathophysiology of cancer immunotherapy resistance focusing on tryptophan metabolism
Authors: Ninomiya Soranobu
Published: June 2021

Associate Professor Soranobu Ninomiya, Graduate School of Medicine, Gifu University, Japan, is investigating the potential for IDO, a tryptophan-metabolising enzyme that is highly expressed in tumours, to be used in cancer treatment. He is building on existing knowledge that intratumor
IDO expression and serum kynurenine levels are useful as prognostic factors in cancer patients. The treatment that Ninomiya and the team are developing blocks the action of IDO in cancer cells, thereby enhancing the effect of cancer immunotherapy as IDO weakens the power of immunocytes. Advances
in cancer immunotherapy and specifically immune checkpoint inhibitors have led to new cancer treatments, with their effectiveness confirmed by CART therapy. Using a mouse model, Ninomiya and the team elucidated the usefulness of CD19-CART therapy, which is a novel cancer immunotherapy for
the treatment of diffuse large B-cell lymphoma (DLBCL), and IDO inhibitor combination therapy. The researchers also clarified that tryptophan deficiency in the serum can cause skeletal muscle atrophy, by using myoblasts and skeletal muscles of a mouse and, in addition, examined muscular atrophy
using CT images of cancer patients. Ninomiya and the team are confident that IDO has great potential to be a candidate therapeutic target for patients with DLBCL, especially those who have been found to be resistant to chemotherapy.
Application of human iPS cell-derived vascular cell differentiation induction method to elucidation of vascular pathology
Authors: Taura Daisuke
Published: June 2021

Cardiovascular diseases such as arteriosclerosis are a leading cause of death in developed countries. Various factors, including diet, exercise and genetics, can play a role in the onset of such conditions and the development of treatment options is complex and often involves the use
of animal models. However, there are limitations with the use of animal models due to their inherent differences to humans, meaning that research results aren't always translatable. Associate Professor Daisuke Taura, Department of Diabetes, Endocrinology and Nutrition, Kyoto University, Japan,
is interested in the use of in vitro techniques for investigating cardiovascular conditions. He is conducting vascular cell differentiation induction research using human embryonic stem cells (ES) cells and induced pluripotent cells (iPS), which can be induced to differentiate into any type
of human cell, provided the right culturing conditions are present. In a world first, Taura successfully induced vascular constituent cells from human iPS cells, which led to important results in the establishment of vascular cells with autosomal dominant polycystic kidney disease (ADPKD)
and moyamoya disease. Ultimately, Taura and his team are working towards a radical treatment for atherosclerotic diseases, and are also seeking to induce differentiation of vascular constituent cells using human ES/ iPS cells and explore their development and differentiation processes. Taura
has been successful in improving on culture methods and, in doing so, achieved the differentiation of human ES cells into vascular endothelial cells and mural cells, and the differentiation of human iPS cells into vascular endothelial cells and mural cells.
Clarifying the mechanism of complement activation in sepsis patients
Authors: Sueyoshi Koichiro
Published: June 2021

Sepsis occurs when the body has an extreme reaction to infection and the patient's condition worsens. Most types of infection can lead to sepsis but, commonly, infections start in the lung, urinary tract, skin or gastrointestinal tract. Sepsis can lead to multiple organ failure, complications
and death. There remains uncertainty surrounding the actual causes of multiple organ failure from sepsis and greater clarity is required in order to develop treatments and improve patient outcomes. Associate Professor Koichiro Sueyoshi, Emergency and Critical Care Center, Juntendo University
Urayasu Hospital, Japan, is working to better understand the reasons for multiple organ failure in sepsis patients. He is collaborating with Professor Hiroshi Tanaka, Professor of Emergency and Disaster Medicine, Juntendo University, and the researchers have developed a hypothesis that one
of the main causes for multiple organ failure in sepsis patients is complement activation. Now, the team is working to prove this hypothesis. The researchers are working to determine whether uncontrolled complement activation occurs during biological infection and whether thrombotic microangiopathy
(TMA) is triggered, leading to multiple organ failure. If Sueyoshi and the team succeed in clarifying the mechanism of complement activation in the process of developing multiple organ failure and the involvement of TMA pathology this could pave the way for new treatment strategies for multiple
organ failure. In addition, the work could fundamentally change existing thought surrounding infection reactions.

In this work, atomically clean and structurally ordered surface of CdTe epitaxial layer after storage in air by treatment in isopropyl alcohol saturated with vapors of hydrochloric acid, and further temperature heating in an ultrahigh vacuum, was obtained. CdTe surface chemical treatment results in the removal of native oxides and surface enrichment with elemental tellurium. Heating in vacuum leads to the tellurium desorption and the appearance of a Te-stabilized CdTe surface. During heating in vacuum, two stages of surface state change are observed (~125°С and ≤250°С). At Т>250°С, elemental tellurium is desorbed and a Te-stabilized structure (1x1) CdTe(013) is formed.

Установлено, что при выращивании нитевидных нанокристаллов Si в потоке Н2, не подвергшемся дополнительной очистке от остатков О2 и паров воды, на поверхности кристаллов и на ростовой подложке образуются слои SiO2. Из-за присутствия оксидного поверхностного слоя рост нитевидных нанокристаллов Si заторможен, кристаллы характеризуются сильной морфологической неустойчивостью. Определены термодинамические условия образования поверхностного оксидного слоя и его влияния на рост нитевидных нанокристаллов Si. При температурах синтеза 750-1400 K нитевидные кристаллы Si термодинамически неустойчивы в газовой фазе, содержащей любые ощутимо малые концентрации O2, и при благоприятных кинетических условиях Si должен всецело превращаться в оксид. Термическая диссоциация и водородное восстановление SiO2 в условиях роста кристаллов Si практически неосуществимы. Ключевые слова: нитевидные нанокристаллы, кремний, рост, оксидный слой.

Authors: Martinengo Laura , Lo Nicholas Y W , Goh Westin I W T , Tudor Car Lorainne
Published: June 2021

Background

Conversational agents or chatbots are computer programs that simulate conversations with users. Conversational agents are increasingly used for delivery of behavior change interventions in health care. Behavior change is complex and comprises the use of one or several components collectively known as behavioral change techniques (BCTs).

Objective

The objective of this scoping review is to identify the BCTs that are used in behavior change–focused interventions delivered via conversational agents in health care.

Methods

This scoping review will be performed in line with the Joanna Briggs Institute methodology and will be reported according to the PRISMA extension for scoping reviews guidelines. We will perform a comprehensive search of electronic databases and grey literature sources, and will check the reference lists of included studies for additional relevant studies. The screening and data extraction will be performed independently and in parallel by two review authors. Discrepancies will be resolved through consensus or discussion with a third review author. We will use a data extraction form congruent with the key themes and aims of this scoping review. BCTs employed in the included studies will be coded in line with BCT Taxonomy v1. We will analyze the data qualitatively and present it in diagrammatic or tabular form, alongside a narrative summary.

Results

To date, we have designed the search strategy and performed the search on April 26, 2021. The first round of screening of retrieved articles is planned to begin soon.

Conclusions

Using appropriate BCTs in the design and delivery of health care interventions via conversational agents is essential to improve long-term outcomes. Our findings will serve to inform the development of future interventions in this area.

Identifying smart healthscape quality criteria for geriatric long-term care private hospitals in South Korea: Analytic Hierarchy Process (Preprint)
Authors: Nam Kyungsook , Chun Sookyung
Published: June 2021

BACKGROUND

In the field of healthcare services, intelligent technology is deeply merged in the healthcare services and many general hospitals tried to build smart hospitals for providing smart healthcare services to the patients. However, geriatric long-term care private hospitals (GHs), where providing the elderly patient-suited care services implemented by multiple service providers, should be considered differently than a general hospital. The purpose of this study is to identifying Smart Healthscape Quality (SHQ), to provide the evaluation criteria that can be applied to the context of private sector GHs in South Korea, and to select the priorities for service improvement. In order to specify healthcare services for geriatric patients, this study was based on two rationales: (1) Geriatric long-term care private hospitals (GHs) should be considered differently than a general hospital. (2) patients are perceived service from environments not only includes physical elements but also includes intangible elements such as intelligent system technologies.

OBJECTIVE

The purpose of this study is to identifying Smart Healthscape Quality (SHQ), to provide the evaluation criteria that can be applied to the context of private sector GHs in South Korea, and to select the priorities for service improvement.

METHODS

Previous studies and reviews of existing, well-regarded healthcare-related guidelines that focus predominantly on general hospitals were first reviewed and relevant points were extracted. Next, a group of academics was enlisted to review the proposed criteria and sub-criteria. Then, an analytic hierarchy process (AHP) was employed in which healthcare professionals evaluated the importance (weighting) of each criterion and sub-criterion.

RESULTS

The author identifies and describes 7 criteria (safety, accessibility and layout, ambiance, appealing decorations and facilities, sociality, service, and intelligent system) and 43 sub-criteria. Also, the author provides importance of each criterion and sub-criterion.

CONCLUSIONS

The result of this study provides not only the foundation of the service framework for GHs in South Korea from a healthscape perspective, but also suggests a basis for smart healthscape concerns in private hospital service environments. The main contributions of this study include. 1) a comprehensive framework of SHQ for GHs in South Korea, 2) SHQ that extended the existing healthscape concept, and 3) the strongest-weighted SHQ offer practical support for decision-makers to identify common requirements and areas of improvement when planning GHs services.
THE CERAMIC MODULAR HEAD IMPROVEMENT IN THE DESIGN OF A TOTAL HIP REPLACEMENT
Authors: Pakhaliuk Vladimir , Poliakov Aleksandr , Fedotov Ivan
Published: June 2021

For the first time, a design of a modular ceramic ball head of a total hip joint replacement (THR) friction pair has been developed, which has the properties of a metal in conjunction with the stem neck and the properties of a ceramics on bearing surface of the pair. This is achieved by creating a low-cost, low-toxic, durable fixed connection of the head made of alumina or zirconia ceramics and the titanium-based alloy sleeve to obtain a brazed joint that is efficient in human synovial fluid. With the help of finite element analysis, a quantitative assessment of the strength and rigidity of the proposed head design was performed and its use in modern hip arthroplasty was indicated. The approbation of the proposed design solutions for creating a THR ceramic head with a titanium-based alloy sleeve brazed was carried out.
PERFECTIONISM IN THE CONTEXT OF THE REVISED REINFORCEMENT SENSITIVITY THEORY
Authors: Ranđelovic Kristina , Stojiljković Snežana
Published: June 2021

The main goal of this research was to examine the role of personality traits in predicting the two aspects of perfectionism – maladaptive evaluation concerns and positive strivings. Personality traits were postulated by the Revised Reinforcement Sensitivity Theory, while the dimensions of perfectionism were defined by the Model of Perfectionism developed by Frost et al. The sample consisted of 299 students of the Faculty of Philosophy in Niš (79.3% were female), aged 19 to 29 years (M = 20.34; SD = 1.83). The instruments used were: the Reinforcement Sensitivity Questionnaire (RSQ), and the Multidimensional Perfectionism Scale (MPS). The main takeaways of this research indicate that the Behavioural Inhibition System (BIS) is the strongest and positive correlate of maladaptive evaluation concerns, followed by Freeze and Fight. Unlike personality defence systems, the Behavioural Approach System (BAS) shows a negative correlation with the abovementioned criterion. The total percentage of explained variance for maladaptive evaluation concerns is 23%. When positive strivings are used as the criterion, BAS is seen as a positive correlate only in the first step of the hierarchical regression analysis. However, Flight and Fight represent consistent and positive correlates of this criterion. The total percentage of explained variance for positive strivings is 6.9%. The findings are consistent with the Revised Reinforcement Sensitivity Theory and available empirical findings from previous studies. Moreover, the results indicate that in the context of the abovementioned personality theory, maladaptive evaluation concerns and positive strivings can be understood as maladaptive forms of perfectionism, which deviates from previous understandings of perfectionism.
FACTORS CONTRIBUTING TO BETTER ADAPTATION TO INFERTILITY

Published: June 2021

Ever since the importance of the psychological aspects of infertility was recognized, researchers have been trying to define adaptation to this non-developmental crisis. Lately, more popular research has been concerned with the question of which factors contribute to better adaptation, rather than what that adaptation is. The majority of these studies are carried out with women who still face infertility, while the women who became parents after facing this crisis are included in just a few studies. Accordingly, the main aim of this research was to examine the opinion on the factors contributing to better adaptation to infertility, as well as the differences in opinion between women who took on the parental role after coping with infertility and those who did not. For that purpose, the Infertility Adaptation Factors Questionnaire was applied on a sample of 192 respondents. The questionnaire consists of 23 items, with four different factors. In their opinion, among the examined factors, the most important is togetherness and intimacy between partners, which is statistically more important than resources, social support and importance of the parental role, the least important factor in this study. There are no significant differences between those who became parents and those who are still dealing with infertility.

Published: June 2021

This study tackles the role of the ESP teacher, course design, teaching techniques, and evaluation procedures. It further focuses on evaluating teaching techniques which should improve student reading comprehension, which operates at multiple levels, by applying Bloom’s six levels to in-class reading tasks. To accomplish this, twelve B2 level students engaged in activities that revolve around their reading of a text for specific purposes. Through these activities, teaching techniques were assessed and student comprehension was evaluated on each of the six levels. The activities used for research at level 1 were done in person in the classroom. The research activities for levels 2-6 were arranged through an eLearning platform, and students worked independently to complete them and return them to the teacher via the Internet. The research method used was action research. Based on the findings, it is aimed to offer answers and suggestions that may be useful for EAP and ESP teachers. The research has shown that using reading comprehension strategies at all levels of Bloom’s taxonomy in achieving comprehension is beneficial not only in language education, but also for development of the higher order thinking skills of adolescents. It equips them with the ability to think critically and creatively, and provides them with vital tools that they will use during their whole life.
