A HOLISTIC DROP OUT PREVENTION PROGRAM FOR VOCATIONAL AND TECHNICAL SECONDARY EDUCATION INSTITUTIONS
Authors: GÜNGÖR Gündüz
Published: December 2022

The purpose of this study is to determine suggestions for the prevention of dropping out according to the opinions of administrators and teachers of vocational high schools and to apply the Holistic School Drop Out Prevention Program
(HSDP) to the ninth-grade students who repeat the class and to determine the success rate (effectiveness) of reducing the school drop rate in the vocational high school where the study is conducted. This research is a mixed-method
case study designed with an Exploratory Sequential Design. The ninth-grade students who had repeated their grades in two vocational high schools which were supposed to have similar properties in Mersin were determined as experimental
and control groups. There were 46 students in the control group and 71 students in the experimental group. HSDP was applied to the experimental group students and there was not conducted any research on the control group students.
After the HSDP was applied in the 2017-2018 academic year, the ratio test, which is a quantitative method, was used to compare the school dropout rates of the experimental and control groups and a significant difference was found
in favor of the experimental group. Then, the semi-structured interview technique, which is a qualitative method, was used to get the opinions of the administrators, school counselors and experimental group students about the effectiveness
of HSDP. The results obtained from qualitative data indicate that HSDP is successful.

Authors: BULUT Ayhan , KABAN Abdullatif , BİLEN Ömer , KUZEY Memet
Published: December 2022

The aim of this study is to describe the perceptions of teacher candidates attending various programs of education faculties regarding the concept of "Pedagogical Formation", which directly makes the appointment and employment conditions
even more difficult. In this study, the phenomenology design, one of the qualitative research methods, was employed. The study group of the research consists of 150 teacher candidates who study in various departments of the Faculty
of Education of Bayburt University in the 2021-2022 academic year and voluntarily supported the research. The data were analyzed using the content analysis method. The metaphors developed by the teacher candidates for the concept
of pedagogical formation were classified into 9 different categories. When the distribution of the metaphors developed by the teacher candidates regarding the concept of "pedagogical formation" into categories is examined, the
first three categories are as follows: “Pedagogical formation as an element dependent on effort and time (29.93%), Pedagogical formation as a useless phenomenon that can be reached without effort (27.00%), Pedagogical formation
as direction and guide (13.86%). As a result, the teacher candidates likened the concept of pedagogical formation to a long marathon that requires effort with full of deep secrets, and they also stated that they see it as a lifelong
process, as a richness that adds value to people, and as a mandatory need in the life of the individual. In addition, it was concluded that some teacher candidates who continue on to the education faculty have a negative attitude
toward the concept of pedagogical formation, as they do toward the pedagogical formation certificate program that grants the right to teach to candidates who have completed various undergraduate programs other than education faculty
programs.

Authors: Rahmawati Yustika , Kismiyati Kismiyati , Lamid Mirni
Published: December 2022

Ikan mas (Cyprinus carpio) merupakan ikan konsumsi air tawar memiliki beberapa keunggulan dimana pertumbuhannya cepat, mudah dipelihara, memiliki nilai gizi yang baik dan bernilai ekonomis. Permintaan terhadap produk ikan mas cukup tinggi. Total produksi Ikan mas nasional pada tahun 2019 mendekati 536 ribu ton (KKP, 2021). Peningkatan produksi ikan mas berakibat pada penyediaan ikan mas yang cukup dan berkualitas pada proses budidaya. Menurut Faroq (2020), pemberian pakan yang dicampur enzim bonggol nanas dapat meningkatkan laju pertumbuhan harian tertinggi dan efisiensi pakan. Pakan yang lebih efisien diharapkan ikan dapat lebih bertahan ketika terinfeksi parasit Argulus japonicus. Penelitian ini bertujuan untuk mengetahui efek enzim bromelin pada bonggol nanas terhadap efesiensi pakan dan patologi anatomi pada ikan mas (Cyprinus carpio) yang diinfestasi Argulus japonicus. Pada penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola faktorial yang terdiri dari 2 faktor dengan 4x2 perlakuan yaitu faktor pertama dosis enzim bromelin 2,25% dan tanpa penambahan enzim bromelin. Faktor kedua yaitu derajat infestasi argulus ringan, sedang, dan berat. Hasil penelitian menunjukkan efesiensi pakan dan patologi anatomi yang tidak berbeda nyata terhadap pemberian enzim bromelin pada ikan mas yang diinfestasi Argulus japonicus. Namun perlakuan dengan penambahan enzim bromelin yang diinfestasi Argulus japonicus memberikan nilai efesiensi pakan lebih tinggi dan nilai patologi anatomi lebih rendah dibandingkan dengan perlakuan tanpa pemberian enzim bromelin yang diinfestasi Argulus japonicus.

Sosiaalinen media kotimaisissa realistisissa nuortenromaaneissa
Authors: Huhtinen Hanna
Published: December 2022

Mistä kumpuaa pakonomainen tarve olla jatkuvasti läsnä sosiaalisen median kanavilla ja miten nuoret internetissä toimivat? Problematiikkaa käsitellään parasta aikaa suomalaisessa nuortenkirjallisuudessa. Länsimaiden digitalisoitumisen seurauksena 2000-luvun kahden ensimmäisen vuosikymmenen suomalaisessa nuorten proosassa esiintyy tuon tuostakin intermediaalisia digitaaliteknologian kuvauksia ja enenevästi myös sosiaalisen median alustojen ja niiden käytön kuvausta.
Artikkelissa tarkastellaan sellaisia kotimaisia, nuorille suunnattuja proosateoksia, jotka sivuavat tai tematisoivat sosiaalista mediaa. Laajan kirjallisuuskatsauksen avulla muodostuu kuva siitä, millaisia funktioita sosiaalisen median representaatioilla nuortenkirjallisuudessa on ja miten fiktiossa suhtaudutaan teknologiseen determinismiin. Deterministinen lähestymistapa hahmottuu monessa tapauksessa teknologiapessimismiksi. Erityisesti näin tapahtuu Jukka Behmin Pehmolelutyttö-romaanissa (2017), joka käsittelee sosiaalista mediaa groomingin näkökulmasta. Grooming tarkoittaa internetin välityksellä tapahtuvaa rikollista lasten ja nuorten houkuttelua ja valmistelua seksuaalista riistoa varten.
Kaunokirjallisuus osallistuu keskusteluun sosiaaliseen mediaan liittyvistä kulttuurisista merkityksistä. Nuortenproosan sosiaalisen median representaatiot heijastavat digitalisoitunutta suomalaista yhteiskuntaa. Teknologiaa käsitellään kuitenkin kriittisestä, sen aiheuttamiin lieveilmiöihin keskittyvästä näkökulmasta, joka ei ole yhtä selkeästi vallalla muussa institutionaalisessa keskustelussa. Nuoret kohtaavat fiktiossa konflikteja, jotka korostavat teknologiapessimismiä nuorten suojelutarpeeseen liittyvänä esitystapana. Toisaalta sosiaalisen median aiheuttamiin ongelmiin suhtaudutaan myös huumorilla, ja nuoria pyritään voimauttamaan.
Comparison of security arguments of promising key encapsulation mechanisms
Authors: Gorbenko Yu.I. , Kandii S.O.
Published: December 2022

The study of key encapsulation mechanisms on algebraic lattices is one of the important directions in modern post-quantum cryptography, since many mechanisms are already either standardized (ANSI X.9.98, DSTU 8961:2019 "Skelya") or are promising candidates for standardization (CRYSTALS-Kyber, FrodoKEM). The purpose of this work is to compare the security arguments of DSTU 8961:2019 "Skelya", CRYSTALS-Kyber, FrodoKEM key encapsulation mechanisms. The paper provides a comparison of theoretical evidence in the idealized random oracle (ROM) and quantum random oracle (QROM) models, as well as a comparison of specific values ​of security parameters in the core-SVP model, which is, in fact, a standard for lattice cryptography. Since all three key encapsulation mechanisms are based on different complex problems (NTRU, Module-LWE, LWE), a comparison of complex lattice theory problems and a comparison of their security arguments are additionally given. The strengths and weaknesses of the considered key encapsulation mechanisms are shown, and areas of research that require more detailed attention are highlighted.
FALCON signature vulnerability to special attacks and its protection
Authors: Derevianko Ya.A. , Gorbenko I.D.
Published: December 2022

It is well known that quantum algorithms offer exponential speedup in solving the integer factorization and discrete logarithm problems that existing public-key systems rely on. Thus, post-quantum cryptography seeks alternative classical algorithms that can withstand quantum cryptanalysis. Growing concern about the quantum threat has prompted the National Institute of Standards and Technology (NIST) to invite and evaluate applications for a post-quantum cryptography standard, an ongoing process scheduled to be completed by 2023.

Falcon is an electronic signature algorithm based on the mathematics of algebraic lattices. The disadvantage of this algorithm is the small number of studies of resistance against special attacks, as well as attacks through side channels.

This material examines existing attacks on the implementation, and also analyzes the speed with applying countermeasures that would prevent such attacks. Although the Falcon scheme sampler, as well as certain mathematical transformations, are still vulnerable to attacks (which in turn allow the private key to be obtained), the efficiency of the components and mathematics of this signature algorithm make it competitive with other schemes, even with countermeasures against these attacks.

The work will also consider the attack by side channels on the Falcon. Such an attack is a known-plaintext attack that uses the device's electromagnetic radiation to derive secret signature keys, which can then be used to forge signatures in arbitrary messages. The obtained results show that Falcon is quite vulnerable to side-channel attacks and does not yet have protection against such attacks in the proposed implementation. Because of this, standardization or implementation should consider the possibility of physical attacks, as well as options for countering such attacks.
Status report on the third round of the NIST post-quantum cryptography standardization process
Authors: Yesina M.V. , Ostrianska Ye.V. , Gorbenko I.D.
Published: December 2022

In recent years, there has been steady progress in the creation of quantum computers. If large-scale quantum computers are implemented, they will threaten the security of many widely used public-key cryptosystems. Key-establishment schemes and digital signatures based on factorization, discrete logarithms, and elliptic curve cryptography will be most affected. Symmetric cryptographic primitives such as block ciphers and hash functions will be broken only slightly. As a result, there has been an intensification of research on finding public-key cryptosystems that would be secure against cryptanalysts with both quantum and classical computers. This area is often called post-quantum cryptography (PQC), or sometimes quantum-resistant cryptography. The goal is to design schemes that can be deployed in existing communication networks and protocols without significant changes. The National Institute of Standards and Technology is in the process of selecting one or more public-key cryptographic algorithms through an open competition. New public-key cryptography standards will define one or more additional digital signatures, public-key encryption, and key-establishment algorithms. It is assumed that these algorithms will be able to protect confidential information well in the near future, including after the advent of quantum computers. After three rounds of evaluation and analysis, NIST has selected the first algorithms that will be standardized as a result of the PQC standardization process. The purpose of this article is to review and analyze the state of NIST's post-quantum cryptography standardization evaluation and selection process. The article summarizes each of the 15 candidate algorithms from the third round and identifies the algorithms selected for standardization, as well as those that will continue to be evaluated in the fourth round of analysis. Although the third round is coming to an end and NIST will begin developing the first PQC standards, standardization efforts in this area will continue for some time. This should not be interpreted as meaning that users should wait to adopt post-quantum algorithms. NIST looks forward to the rapid implementation of these first standardized algorithms and will issue future guidance on the transition. The transition will undoubtedly have many complexities, and there will be challenges for some use cases such as IoT devices or certificate transparency.
Analysis of views of the European Union on quantum-post-quantum limitations
Authors: Ostrianska Ye.V. , Yesina M.V. , Gorbenko I.D.
Published: December 2022

Virtually all asymmetric cryptographic schemes currently in use are threatened by the potential development of powerful quantum computers. Although there is currently no definite answer and it is very unclear when or even if CRQC will ever be built and the gap between modern quantum computers and the envisioned CRQC is huge, the risk of creating CRQC means that currently deployed public key cryptography must be replaced by quantum-resistant ones alternatives. For example, information encrypted using modern public key cryptography can be recorded by cryptanalysts and then attacked if a QRQC can be created. The potential harm that CRQC could cause is the basis of the motivation to seek countermeasures, even though we have uncertainties about when and if these computers can be built. Deployed systems that use public key cryptography can also take years to update. Post-quantum cryptography is one way to combat quantum computer threats. Its security is based on the complexity of mathematical problems that are currently considered unsolvable efficiently – even with the help of quantum computers. Post-quantum cryptography deals with the development and research of asymmetric cryptosystems, which, according to current knowledge, cannot be broken even by powerful quantum computers. These methods are based on mathematical problems for the solution of which neither efficient classical algorithms nor efficient quantum algorithms are known today. Various approaches to the implementation of post-quantum cryptography are used in modern research, including: code-based cryptography, lattice-based cryptography, hashing-based cryptography, isogeny-based cryptography, and multidimensional cryptography. The purpose of this work is to review the computational model of quantum computers; quantum algorithms, which have the greatest impact on modern cryptography; the risk of creating cryptographically relevant quantum computers (CRQC); security of symmetric cryptography and public key cryptography in the presence of CRQC; NIST PQC standardization efforts; transition to quantum-resistant public-key cryptography; relevance, views and current state of development of quantum-resistant cryptography in the European Union. It also highlights the progress of the most important effort in the field: NIST's standardization of post-quantum cryptography.

This review is devoted to analysis of works in the field of creating electrically insulating heat-conducting polyimide composite films based on powders of micro-, submicro- or nano-sized fillers with high dielectric and heat-conducting properties for use as effective thermal interface materials in various electronic devices in instrument making. Particular attention is paid to studies on the influence of the size of nano- and microparticles of inorganic fillers on the heat-nducting, dielectric, and physical-mechanical properties of nanocomposite polyimide materials. The analysis of the results of work on the study of the dependence of thermal conductivity on the ratios of micron and nanosized particles in mixtures and their number in polyimides and on the conditions of their polymerization was carried out to confirm the possibility of increasing the thermal conductivity values of promising polyimide materials from 0.12 W/(m•K) up to 5¸10 W/ (m•K). It is noted that the highest thermal conductivity of industrially produced modern polyimide films on market does not exceed 0.75¸0.8 W/(m•K). The task of creating inexpensive, but high-quality heat-conductive polyimide composite materials with sufficiently high thermal conductivity without deteriorating their strength and ductility characteristics is currently relevant and technically in demand.

Published: December 2022

Objective: Breast-conserving surgery (BCS) experienced a significant surge during the last decades due to the increase of early breast cancer detection. Central to the discussion is margin adequacy which represents one of the most significant predictive factors for local relapse. This paper aims to shed light on the problem of margins in breast surgery. Mechanism: We performed a systematic narrative review of the literature by conducting a search using Medline/PubMed, Scopus, and Embase. The following keywords were considered: “breast-conserving surgery” AND “margins”/“margin”. Findings in Brief: In the case of invasive breast cancer, “no ink on tumor” can be considered an adequate margin, while for ductal carcinoma in situ (DCIS), a distance of 2 mm from tumor should be obtained. Many novel tools have been developed based both on the latest radiological imaging techniques and on the tissue expression of certain markers, with the aim of precise navigation of tumor excision and intraoperative evaluation of cavity excision margins. Oncoplastic surgery can be considered oncologically safe while improving the cosmetic outcome and patients’ quality of life. The appropriate use of adjuvant treatments in the context of a multidisciplinary and personalized management of breast cancer is the only means to omit a second intervention in some carefully selected cases. Conclusions: Debate still exists concerning the definition of adequate clear margin following BCS for DCIS. Further studies are required to better assess multimodal treatment approaches in this condition.

Published: December 2022

Background: We analyzed both early and late (persistent) phases of each cytomegalovirus (CMV) antibody in mothers with primary CMV infection during pregnancy and subsequent congenital CMV infection for a long period from late pregnancy to after delivery using our stored serum samples. Methods: We used stored serum samples obtained during pregnancy to after delivery from mothers with CMV immunoglobulin (Ig) G seroconversion and subsequent infant congenital CMV infection. CMV antibodies, including CMV IgG titer, IgM titer, and IgG avidity, were assessed using the Denka IgG assay, Denka IgM assay Ver.1 and Ver.2, and Enzygnost IgG assay and Denka IgG avidity assay, respectively. We analyzed the dynamics of each CMV antibody for a long period from late pregnancy to after delivery and correlations of each antibody, calculating Pearson’s correlation coefficients (R2). Results: We used 67 serum samples obtained from 12 included participants between 2013 and 2018. CMV IgG increased until 61 weeks and did not change significantly after. CMV IgM decreased until 52 weeks and did not change significantly after that in both assays. CMV IgG avidity increased until 64 weeks and did not change significantly after that in both assays. In CMV IgM, a strong positive correlation was found (R2 = 0.9326) between the two different IgM assays. Serum results of the late phase (after 60 weeks) were subsumed into the area of high CMV IgG avidity and low CMV IgM titer, which probably was equivalent to the persistent IgM. Conclusions: CMV antibodies in mothers during the late phase of primary infection were in high IgG avidity and low IgM titer, which probably was equivalent to the persistent IgM.
Comparison of Myocardial Injury and Inflammation Biomarkers and Their Impact on Recurrence after Cryoballoon and Radiofrequency Ablation for Atrial Fibrillation: A Systematic Review and Meta-Analysis
Authors: Zhou Xinbin , Xue Hong , Chen Qian , Lv Zhengtian , Mao Wei , Wang Xiao
Published: December 2022

Background: Biomarkers of myocardial injury and inflammation were found to be different after radiofrequency catheter ablation (RFCA) and cryoballoon ablation (CBA) for atrial fibrillation (AF); however, the results are currently controversial. This study was aimed to systematically compare the differences in myocardial injury and inflammation biomarkers after RFCA and CBA procedures and to investigate their impact on AF recurrence. Methods: Databases, including PubMed, Embase, the Cochrane Library, ClinicalTrials.gov, China National Knowledge Infrastructure (CNKI) and China Biology Medicine (CBM), were systematically searched from their date of inception to May 2022. The primary outcomes of interest were the differences in myocardial injury and inflammation biomarkers after CBA and RFCA procedures for AF patients, and the impact of the biomarkers on AF recurrence. Secondary outcomes included the total ablation time, the procedure duration and the freedom from atrial tachycardia (AT). Results: Eighteen studies with a total of 1807 patients were finally enrolled. CBA treatment was associated with significantly greater increases in troponin I (TNI) levels (weighted mean difference [WMD] = 3.13 ug/L, 95% confidence interval [CI] 2.43–3.64) both at 4–6 h (WMD = 3.94 ug/L), 24 h (WMD = 4.23 ug/L), 48 h (WMD = 2.14 ug/L) and 72 h (WMD = 0.56 ug/L), and also creatine kinade MB fraction (CK-MB) levels at 4–6 h (WMD = 33.21 U/L), 24 h (WMD = 35.84 U/L) and 48 h (WMD = 4.62 U/L), while RFCA treatment was associated with greater increases in postablation C-reactive protein (CRP) levels both at 48 h (WMD = –9.32 mg/L) and 72 h (WMD = –10.90 mg/L). The CBA and RFCA treatments had comparable rates of freedom from AT (74.5% vs. 75.2%, RR = 1.08). The CRP levels were significantly higher in patients with early recurrence of AF (ERAF) than in those without ERAF after RFCA treatment (WMD = 3.415 mg/L). Conclusions: The time-course patterns of postablation myocardial injury and inflammation biomarkers are different between RFCA and CBA procedures. The lower postprocedural elevation of myocardial injury biomarkers and the increased CRP levels may be predictive factors for ERAF. PROSPERO Registration Number: CRD42021278564.
NHHR: An Important Independent Risk Factor for Patients with STEMI
Authors: Gao Po , Zhang Jing , Fan Xizhen
Published: December 2022

Background: In this study, we investigated whether the ratio of non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol (NHHR) is associated with the development of acute ST-segment elevation myocardial infarction (STEMI). Methods: 889 STEMI patients who had not previously received lipid-lowering therapy were selected as the test group and 120 patients with less than 50% coronary stenosis were selected as the control group. All patients completed the related blood tests the morning after admission, and Gensini scores were based on coronary angiography results. The differences were compared using a t-test, rank sum test, chi-square test and logistic regression analysis. Linear regression analysis was used to study the correlation between variables. Receiver Operating Characteristic (ROC) curves were used to validate the predictive value of NHHR for STEMI. Results: NHHR was shown to be a significant independent risk factor for STEMI according to binary logistic regression analysis (OR = 0.163, 95% CI: 0.065–0.411, p < 0.05). There were shown to be differences in the NHHR depending on the gender of the STEMI patients (z = –1.663, p < 0.1). Linear regression analysis revealed a stronger correlation between NHHR and Gensini score (r = 0.394, p < 0.05) in the test group. Finally, we demonstrated that NHHR has a good predictive effect on STEMI, using an ROC curve (Area Under Curve (AUC): 0.818, 95% CI: 0.777–0.859, p < 0.05). Conclusions: NHHR is a good predictor of coronary artery disease severity in STEMI patients and an important independent risk factor for STEMI, especially for patients who have not received lipid-lowering treatment in the past, and male STEMI patients need more stringent lipids management than female STEMI patients.

Published: December 2022

Background: The triglyceride/glucose index (TyG) reflects insulin resistance and predicts the risk of acute ischemic stroke (aIS). However, it is uncertain if this index predicts the severity and outcome of aIS because studies that addressed this question are few and all were performed in Asian subjects. Moreover, there are no studies that focused on patients with hypercholesterolemia. Methods: We studied 997 Caucasian patients who were hospitalized for aIS and had hypercholesterolemia. aIS severity was assessed at admission with the National Institutes of Health Stroke Scale (NIHSS) and severe aIS was defined as NIHSS ≥21. The outcome was assessed with the functional outcome at discharge and with in-hospital mortality. An unfavorable functional outcome was defined as modified Rank in scale (mRs) at discharge between 3 and 6. Results: The TyG index did not correlate with the NIHSS at admission (r = 0.032, p = NS) and was similar in patients with severe and non-severe aIS (8.7 ± 0.6 and 8.6 ± 0.6, respectively; p = NS). Risk factors for severe aIS were age, female gender, atrial fibrillation (AF) and diastolic blood pressure (DBP) at admission. The TyG index also did not correlate with the mRs(r = 0.037, p = NS) and was similar in patients who had unfavorable and favorable functional outcome (8.7 ± 0.6 and 8.6 ± 0.5, respectively; p = NS). Risk factors for unfavorable functional outcome were age, previous ischemic stroke, body mass index and the NIHSS at admission. The TyG index was similar in patients who died during hospitalization and patients who were discharged (8.7 ± 0.6 and 8.7 ± 0.6, respectively; p = NS). Risk factors for in-hospital mortality were AF and DBP and NIHSS at admission. Conclusions: The TyG index does not appear to be associated with the severity or the outcome of aIS. Nevertheless, since there are few relevant data in Caucasians and the TyG index is an inexpensive and widely available biomarker, more studies in this ethnic group are required to determine the predictive role of this index in patients with aIS.

Authors: Urbanowicz Tomasz , Olasińska-Wiśniewska Anna , Gładki Marcin , Jemielity Marek
Published: December 2022

The inflammatory background of coronary artery disease is gaining more attention in recent times. Off pump surgery is minimally invasive type of surgical revascularization with relatively low number of applications in cardiac surgery centers worldwide that allows for perioperative inflammatory reactions minimalization. The simple inflammatory markers (neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), platelets to lymphocyte ratio (PLR), systemic inflammatory index (SII), systemic inflammatory response index (SIRI), aggregate index of systemic inflammation (AISI)) possess a clinically significant impact on patients’ prognosis and may help to improve patients’ long-term results. The review presents the current knowledge regarding their utility in clinical practice. Assessment of inflammatory indices obtained from whole blood count analysis allows to indicate those patients who need scrupulous follow-up due to predicted worse long-term survival. Perioperative measurement and analysis of simple whole blood counts is inexpensive and easily available and may improve the results of surgical revascularization by better identification of patients at higher risk of worse outcomes.

Excimer Laser coronary atherectomy as adjunctive treatment of severe stent underexpansion with bulky calcification
Authors: Kanhouche Gabriel , Marchi Maurício , Ribeiro Marcelo , Campos Carlos , Nunes Filho Antonio , Ribeiro Henrique
Published: December 2022

Excimer Laser coronary atherectomy has improved significantly in recent years, emitting high-energy ultraviolet and short wavelength with less penetration and heat emission, ultimately leading to less tissue damage and fewer complications. We described a case of a 66-year-old male patient, former smoker and suffering from hypertension, diabetes mellitus, and dyslipidemia. He underwent multiple percutaneous coronary interventions in the left anterior descending artery with bare metal and drug-eluting stents. In the last percutaneous coronary intervention, the stent was underexpanded and the patient presented acute stent thrombosis and recurrent stent restenosis. New percutaneous coronary interventions with adjunctive Excimer Laser coronary atherectomy were undertaken due to refractory angina, using progressive load and saline injection, followed by subsequent high-pressure balloon inflation and drug-eluting stent implantation with an excellent result. At 8-month follow-up, the patient was asymptomatic.
Exploratory Factor Analysis (EFA) in Quantitative Researches and Practical Considerations

Published: December 2022

Explanatory factor analysis (EFA) is a multivariate statistical method frequently used in quantitative research and has begun to be used in many fields such as social sciences, health sciences and economics. With EFA, researchers focus on fewer items that explain the structure, instead of considering too many items that may be unimportant and carry out their studies by placing these items into meaningful categories (factors). However, for over sixty years, many researchers have made different recommendations about when and how to use EFA. Differences in these recommendations confuse the use of EFA. The main topics of discussion are sample size, number of items, item extraction methods, factor retention criteria, rotation methods and general applicability of the applied procedures. The abundance of these discussions and opinions in the literature makes it difficult for researchers to decide which procedures to follow in EFA. For this reason, it would be beneficial for researchers to gather different information about the general procedures (sample number, rotation methods, etc.) in the use of EFA. This paper aims to provide readers with an overview of what procedures to follow when implementing EFA and share practical information about the latest developments in methodological decisions in the EFA process. It is considered that the study will be an important guide for the researchers in the development of clear decision paths in the use of EFA, with the aspect of presenting the most up-to-date information collectively.

Prior literature reviews of study abroad outcomes (Miller & Perrin-Thompson, 2014; Twombly et al., 2012; Varela, 2017) have provided important direction for the field, yet they either were conducted without clear inclusion criteria or excluded qualitative research. In the current scoping review, we extend their work through conducting a systematic literature search inclusive of qualitative research and map the knowledge base of study abroad for students enrolled at universities in the United States who received academic credit for study abroad from fall 2001 (post-9/11) to spring 2020 (COVID-19 pandemic onset). We identified 373 articles meeting inclusion criteria and created a database of filterable information (e.g., participant characteristics, program duration) for the included articles. In the current study, we organize and visually display findings, identify gaps in the knowledge base, and recommend future directions for research and research reporting.

Optimization of column layouts in buildings considering structural and architectural constraints
Authors: Zelickman Yakov , Amir Oded
Published: December 2022

Reducing concrete consumption is important as part of the global effort of fighting the climate change, and specifically in concrete flat slabs as these are among the largest cement consumers. In this study we formulate an efficient gradient-based optimization of column locations, that minimizes the slabs’ thickness with constraints on the deflections, bending moments and shear stresses while accounting for architectural considerations. The results show that the columns’ optimal locations are not trivial and that the slab thickness is very sensitive to the columns’ exact locations. Thus, concrete savings in slabs of up to 20% are possible with minor modification to traditional layouts of columns, and up to 50% with more pronounced updates, which emphasizes the importance of early collaboration between architects and engineers. The results indicate the critical trade-off between structural efficiency and architectural freedom and demonstrate the potential of formal optimization in structural design.
