Authors: Dhilip P. , Niththiyanandam M. , Sethupathi N. , Mahalingam P.
Published: February 2020

Composites consist of layers of cobalt doped tungsten oxide and reduced graphitic oxide was prepared using jet nebulized spray pyrolysis technique. A mixture of ammonium tungstate and cobalt acetate solution was coated on glass substrate at 380 °C using jet nebulized spray pyrolysis technique. Spray technique is used to form the reduced graphene oxide (rGO) layer over the first layer and again ammonium tungstate and cobalt acetate solution coated over the surface of rGO and then calcined in nitrogen atmosphere at 450 °C for 2 h. The composite were characterized using XRD, SEM, PL, CV and EIS studies. The SEM and XRD reveal the layered structure. Cyclic voltammetry reveals the high specific capacitance 500 Fg-1 at 5 mV s-1 scan rate for 2 M Na2SO4 as electrolyte. Layered structure of CoWO4/rGO/CoWO4 composite enhances the specific capacitance. EIS gives the electrical series resistance of 7.9 Ω. The layered CoWO4/rGO/CoWO4 composite can be suitable electrode materials for supercapacitor.

Authors: Karwadi  , Daimah
Published: February 2020

The involvement of women in acts of intolerance and radicalism disturbs religious harmony in Indonesia. The phenomenon of the Surabaya bombing involving women as the main perpetrators of acts of terrorism proves that acts of terrorism, which initially had a patriarchal masculine face, later made use of women with their feminine approaches. In such anxiety arises the Srikandi Lintas Iman Community in Yogyakarta, Indonesia. This community is an alternative for women in sowing the values ​​of diversity, tolerance, and peace among the people. For this reason, it is important to research this community. This study aims to determine the construction and implementation of inclusive religious education built by the interfaith heroine community and the role of women in the development of inclusive religious education. This type of research is qualitative research. The research approach used is the educational sociology approach. The results of the study show that the construction of inclusive religious education in the Srikandi Lintas Iman Community in Yogyakarta stands on the principles and implementation of humanism and democratic values ​​, which include pluralism, justice, equality, doing good to others, and honesty which is manifested in community activities. The implementation of inclusive religious education is classified into several activity groups; religious studies, interfaith dialogue, and interfaith cooperation while the role of women in the development of inclusive religious education in the Srikandi Lintas Iman Community includes the domestic role of the family and the transition role of social and religious communities.
HOW CAN WE STOP THE SEWAGE?

Published: February 2020

In Ecuador 46.4% of households lack access to sewerage systems, and then much wastewater is discharged from sewerage into the environment untreated. On the one hand dry toilet systems present themselves as an optimal solution against this backdrop; they mitigate the production of black water, whilst having fertilizer as the end product. On the other hand, they tend to have a low acceptance level by potential end users. This problem of social acceptance is then further exacerbated in urban areas. In order to overcome this, the design of an ecological dry/semi-dry toilet was carried out in two phases. The first phase consisted of purely sociological research, where the aim was to determine the basic design parameters that should be used for ecological toilet prototype. The second phase is the development of ecological toilet prototypes, which are then tested in terms of their level of acceptance/rejection by potential end users. The overall aim is to develop toilet prototypes that on the one hand mitigate the production of black water, whilst on the other are accepted with open arms by end users, and even preferred over the conventional toilet common to urban areas.

Published: February 2020

Leadership in Environmental and Energy Design, LEED, is one of the most recognized green building certification systems in the world. Turkey is also one of the countries, where it is widely used. It offers different rating groups to address varying requirements of building and project types. LEED-v3 NC, the rating group for new construction, includes seven categories of credits: sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor air quality, innovation, and regional priority. The maximum achievable point is 110. Local conditions significantly affect the achievement of some of the credits, as LEED is originated in the USA. This study focuses on the assessment of 122 LEED-v3 NC certified buildings in Turkey, considering the points achieved in each category. The aim is to understand which categories are successfully fulfilled and more challenging for implementation. Analysis results show that buildings receive higher points from water efficiency, sustainable sites, innovation and regional priorities, when compared to indoor environmental quality, energy and atmosphere and material and resources categories in Turkey. The lowest category is identified as material and resources. This situation should lead the new projects taking precautions to this individual area especially at the beginning of “planning step” in construction process. Recognizing the successful implementations for earning points and the challenging issues in Turkish construction industry regarding green buildings can be of benefit for professionals in this area.
SUSTAINABLE BUILDING DELIVERY PRACTICES
Authors: Gunhan Suat
Published: February 2020

Today’s clients both public and private have additional expectations from builders. Full cycle services capability that includes financing, planning, building, and facilities management started to be pronounced in larger projects. These expectations are mainly driven by sustainability requirements of clients. These projects necessitate a comprehensive planning approach. The comprehensive planning scope includes all project activities from design to post-construction services (facilities management) with collaboration of project stakeholders. There is no defined method of project delivery for sustainable projects yet. The majority of top green building contractors in the United States are experienced in Construction Management at Risk (CMR) and DesignBuild (DB) delivery methods. This research study aims to explore the project delivery processes currently practiced in the United States’ building construction industry. The survey questionnaire was conducted with the selected Top Green Building Contractors (the list of contractors is published in the Engineering News Record Magazine annually). The original list is composed of 100 national construction firms. The San Antonio and Austin firms were invited to participate to the survey questionnaire. The findings reveal the major green building providers’ methods and procedures that are used during sustainable projects’ delivery. The results indicate that the sustainability is seen as more of a common practice for all projects by most survey participants. There is no specific method for sustainable projects yet. A well-defined sustainable building delivery method should ideally originate from DB and/or CMR.

Published: February 2020

Despite the common belief, there is a considerable amount of innovation that occurs in the construction industry. However, the construction industry has been relatively slow to embrace the full potential of many new technologies. Evidence suggests that there is a lag in the uptake and effective implementation of several new technologies such as mechanical rebar splicing system. The objective of this study is to identify the impediments or barriers to the implementation of innovative technologies such as mechanical rebar splicing systems in the construction industry. A comprehensive literature review is conducted to identify and classify the barriers to new technologies dissemination. The findings of this literature review are validated using interviews with the construction industry experts. This study contributes to the state of knowledge by identifying and classifying the barriers that generally hinder the dissemination of new technologies in the construction industry. The practitioners can utilize the findings of this study to design appropriate strategies to overcome the barriers for implementation of new construction technologies. As part of this study, the extent to which the identified barriers have hindered the adoption of rebar splices, a technology that has not been adapted to its full potential. A questionnaire was designed, which was categorized the identified barrier in five major categories of cost, society and regulation, knowledge, marketing, and technical matters. The findings of the survey it was concluded that the lack of knowledge has the highest level of impact.

In order to achieve the results mentioned, a method of proximity to an ideal point was used.
PERFORMANCE ANALYSIS OF EARTHQUAKE RESISTANT BASED URBAN TRANSFORMATION PROJECTS
Authors: Sarsilmaz Tugba , Güney Deniz
Published: February 2020

Earthquakes have often produced economic and social disaster. The last destructive earthquake on west side of the NAFZ is 1999 İzmit (Mw = 7.4). On August 17, 1999, a major earthquake occurred in the Marmara region, western Turkey, with a magnitude Mw = 7.4. The total observable length of the rupture was about 100km. The number of condemned buildings after the earthquakes amounted 23,400. There were 18,373 accounted deaths. First reason of this damage is inadequate design and low construction quality of buildings without control and supervision. The second important result is wrong urbanization policies of local and central government. Among the cities of the well developed and developing countries, it is possible to create urban surroundings resistant to earthquakes by comprehensive mitigation activities. Turkish Government has decided to perform many urban transformation projects in Istanbul in order prevent future seismic damages. However these projects have been started without detailed design and analysis. The aim of this study is to analysis performance of urban transformation projects in Istanbul. The feedbacks are collected from the sides of urban transformation projects such as landowners, constructors, officials, non governal organizations (NGO). Especially Fikirtepe Urban Transformation Projects are analyzed with details. Based on studies on site and later analysis, the performances of urban transformation projects in Istanbul are evaluated.
A COMPARATIVE STUDY BETWEEN CHINA AND USA ON THE INFLUENCING PATH OF TRANSACTION COSTS IN CONSTRUCTION PROJECTS
Authors: Li Huimin , Zhang Chengyi
Published: February 2020

The actual cost of a construction project is composed of not only production costs, but also transaction costs. The presented model includes the uncertainty of the owner’s behavior, the uncertainty of the contractor’s behavior, the uncertainty in the transaction environment and mechanism, and project management efficiency, to illustrate the influence path of the transaction costs borne by the owner. The model is tested by the structural equation modeling (SEM) using the data collected from construction project owners. The finding indicate that uncertainty in the transaction environment and mechanism appears to be the core construct of the model due to its strong linkages with transaction costs and the owner’s behavior, the contractor’s behavior, and project management efficiency. The uncertainty of the contractor’s behavior is also found to affect project management efficiency positively. A certainty behavior on the part of the owner reduces the uncertainty in the transaction environment and mechanism, increases the efficiency of project management, and reduces the transaction costs of construction project.
IMPACT OF BIDDING ENVIRONMENT ON CHANGE ORDERS
Authors: Barbarosoglu Bahadir V. , Arditi David
Published: February 2020

Change orders occur during construction, and usually increase both construction cost and project duration. This paper investigates how change orders are related to the bidding environment. The data used in this study were collected from 74 public building construction projects awarded by the Public Building Commission of Chicago in the seven-year period 2008-2015. The contract values range between $0.3-$70 million, and the total worth of the projects is a little over $1.1 billion. While delay may result in liquidated damages for contractors, increase in project cost can cause financial problems for owners. It is in the interest of owners and contractors to study similar past projects, and to observe how change orders are affected by the level of competition in bidding. Owners must budget for contingencies, and contractors must adjust their resources in anticipation of change orders. It would therefore be quite desirable for owners and contractors to be able to predict the dollar amount and duration implications of potential change orders by making use of past historical data. The prediction of the dollar amount and duration implications of potential change orders before the construction starts can alert construction owners and contractors to potential delays in total project completion time and potential overruns in total project cost. Knowledge about potential change orders creates a predictable environment and improves the relationship between owners and contractors. The results of this study indicate that contractor-driven change orders are positively related to the difference between the lowest and the second lowest bids.

Once a student asked me before class: what are we going to do tomorrow? I said: I don’t know, we will see tomorrow how it goes. The objective of this paper is to confront two different ways of learning, the class versus on site. We usually think that planning for planning might be the solution, but what happens when planning leaves so little chance to chance? Sometimes approaching design problems without a plan, but with tools and scenarios, works better for a student and community. We will confront these two systems for the same design problem to see which deliver better results for the community and the student’s learning process. Which system will make us ready for the unexpected, for the un-planned, for a future scenario where resources will be limited and non-expected, global warming, oil production decrease?
INNOVATIVE SOFT SOIL IMPROVEMENT BY VACUUM DE-WATERING AND DYNAMIC COMPACTION
Authors: Edil Tuncer B.
Published: February 2020

Recently, an innovative soft soil improvement method was advanced in China by integrating and modifying vacuum consolidation and dynamic compaction ground improvement techniques in an intelligent and controlled manner. This innovative soft soil improvement method is referred to as “High Vacuum Densification Method (HVDM)” to reflect its combined use of vacuum de-watering and dynamic compaction techniques in cycles. Over the past ten years, this innovative soft soil improvement technique has been successfully used in China and Asia for numerous large-scale soft soil improvement projects, from which enormous time and cost savings have been achieved. In this presentation, the working principles of the HVDM will be described. A discussion of the range of fine-grained, cohesive soil properties that would make them ideal for applying HVDM as an efficient ground improvement method will be discussed. The economic benefits and environmental benefits of HVDM are elucidated.
UNDERSTANDING THE ENGINEER’S ROLE IN ADMINISTERING THE CONSTRUCTION CONTRACT
Authors: Abdul-Malak Mohamed-Asem U. , El Masri Farah Y.
Published: February 2020

The role of the Engineer has been carried out by the design consulting firm, traditionally in charge of not just designing and providing technical supervision for the construction work, but also of administrating the construction contract and further assisting in adjudication and arbitration processes in the case of disputes arising along the way. However, due to the increase of the projects’ size and complexity, employers nowadays tend to assign other entities for handling the managerial and administrative tasks normally required of the Engineer. Using the FIDIC's 1999 Red Book as a platform, the Engineer's roles have been systematically identified on a clause-by-clause basis, and various statistics as to the roles’ frequency are offered. A method has been devised to properly classify these identified roles. The proposed classification is based on parameters and attributes which include: the exact deduced role; the role’s timing and frequency of application; the time-barring stipulated for its application; the role’s nature, being reactive, proactive, or passive; the role fulfillment capacity; and the role fulfillment exclusivity. The outcome of this work offers employers with a profound understanding of the roles expected of the Engineer in administrating the construction contract, particularly assisting in the apportionment of these roles between or among multiple employer-appointed entities, when such a split in role-assignment is deemed desirable by employers.
REEVALUATION OF THE EFFECT OF COVERING SHEETS FOR REDUCING BUGHOLES ON TUNNEL LINING CONCRETE
Authors: Maeda Tomoyuki , Harada Sari , Moriuchi Mai , Yoshitake Isamu
Published: February 2020

Most tunnel lining concretes have sidewall of negative angle, so bugholes on the concrete surface frequently appear. The bugholes are caused from entrapped air in concrete placing; the part of bugholes remains on concrete surface even after adequate vibrating for consolidation. In the previous investigation, the authors have studied on the generation mechanism of bugholes in a visible test and examined the reducing effects by covering sheet for concrete forms. According to the investigation, it was found that the water-permeable sheet causes color irregularity of concrete surface while the sheet is effective to decrease the bugholes. Hence, the present study also focuses on the effect of sheets reducing bugholes. The foci of this study are to develop an effective sheet for aesthetic of concrete surface and to reevaluate the effectiveness for reduction of bugholes. Fundamental test using a model form and various covering sheets was performed by referring to the previous investigation. The test confirms that the developed sheet adequately contributes on decrease of bugholes without the color irregularity of concrete. The observations may be useful for most concrete construction as well as tunnel lining concrete.
FLEXIBLE SYSTEMS DESIGN
Authors: Cellucci Cristiana , Di Sivo Michele
Published: February 2020

The research explores the relationship between uncertainty, flexibility and Life Cycle Design in the design of complex systems, in general, and in the particular case of the design of building systems. In the architectural-engineering works, conceived as activities aimed at generating new systems, the comparison with the uncertainty is inevitable. There is a wide range of types of uncertainty; a possible simplification is to consider two types of causes of uncertainty, the presence of the internal or external uncertainties to the system. That is the variability of demand (unknowns about the social and economic context) or the variability of technological market (unknowns about the performance of the system), in other words the functional obsolescence and the technological obsolescence. If flexibility is the ability of a system to be easily modified and to respond to changes in the environment in a timely and convenient, then the flexibility can be considered the antidote to obsolescence, or the characteristic of the system that guarantees slippage over time. It’s that property that makes the system resilient able to absorb the shock and/or disturbance without undergoing major alterations in its functional organization, in its structure and in its identity characteristics. In the paper, the flexibility is therefore seen as a fundamental property for designing a generally complex system, and particularly in architectural design, through the identification of design criteria for the implementation of this requirement, that influence on architecture (form more technology) of the system.

Published: February 2020

This research study investigates the effect of fly ash and silica fume on the cement paste hydration. A total of 350 samples of different percentages of each additive were tested and compared with the controlled cement paste without additives. Testing method includes water curing and vacuum curing conditions and involves the use of Forney Universal Testing Machine and MTS Landmark Servohydraulic Testing System (MTS) for compressive strength; Fourier Transfer Infrared Spectroscopy (FTIR) monitored the hydration with spectra; and Scanning Electron Microscope (SEM) generated images for regional analysis. Compressive strength testing demonstrated that silica fume replacement had the highest overall strength under water curing. Replacement of fly ash exhibited the highest overall strength under vacuum curing. The hydration process was monitored with the use of FTIR and SEM. Signatures of CSH which produce most of the concretes’ strength, has been determined and examined from 3 to 56 days. FTIR and SEM testing showed an increase in the change of CSH area with age. SEM testing revealed the formation of pores, CSH, and CH in images at all ages. The area of CSH grows most in early ages and diminishes over time. It is clear that the method of curing makes a difference in hydration. Results indicated that the area at which the possible formation of CSH was determined from each sample, has increased with respect to time; signifying the increase in strength over the course of testing days.
FINANCIAL ISSUES IN PUBLIC PRIVATE PARTNERSHIPS

Published: February 2020

Public-Private Partnerships (PPPs) have gained significant importance in academia, government, and the construction industry over the last three decades. As a result, numerous studies have been published on the topic. These studies investigate various issues associated with PPP projects such as the length of the concession period, the selection of the private consortium, and the laws, rules and regulations that govern PPP implementation. However, there is a lack of systematic overview about issues with particular attention to financial aspects. This paper presents the outcome of a literature review that has been conducted to collect information about financial issues encountered in PPP implementation. This review included a total of 33 papers published in major journals and conference proceedings in the construction field in the last 25 years. At the end of the review, it was possible to identify a set of 19 financial issues that were grouped into five categories, namely (1) financing system, (2) financial market, (3) transaction costs and delays, (4) the public agency, and (5) the private consortium. The choice of focusing on this theme was prompted by the fact that the other issues (i.e., social, legal, and political) are all linked to financial issues. The identification of the salient issues related to financial aspects in PPPs is expected to contribute to the state-of-art in PPP research and implementation as it can pave the way to an empirical investigation that can in turn lead to a streamlining of the PPP processes throughout the world.
EFFECTS OF FOUNDATION SETTLEMENT ON IN-PLANE BUCKLING OF SHALLOW ARCHES
Authors: Fan Xiaochun , Yu Yu , Pi Yong-Lin , Bradford Mark Andrew
Published: February 2020

Foundation settlement of structures may take place and it may influence the structural behavior of structures. Shallow arches are used in engineering structures such as large span roofs and bridges. This paper is concerned with the effects of the foundation settlement on the in-plane buckling of shallow circular arches under a uniform radial load. Because the deformations of a shallow arch prior to buckling become nonlinear, their effects on the buckling also need to be considered. Differential equations of equilibrium for the nonlinear analysis are derived using the principle of virtual work. Analytical solutions for the nonlinear behavior and for the nonlinear buckling load are obtained. It is found that the foundation settlement plays an important role in the nonlinear structural response of the arch to the external load and that significantly influence the nonlinear buckling load of the arch.
SKEW PLACEMENT OF ARCHES FOR ROAD BRIDGES
Authors: De Backer Hans , Outtier Amelie , Schotte Ken , Nagy Wim , Diversi Marco
Published: February 2020

This article describes a parametric study using a detailed finite element model of an arch bridge consisting out of a single arch with varying arch and hanger arrangement. The objective is to investigate the influence of overall arch dimensions, these different hanger arrangements and a variation of the skewness angle between the arch axis and the longitudinal bridge deck axis. The influence on the stresses, normal forces and bending moments in the main girders, hangers and arch cross-section is examined. Finally, a buckling analysis is performed for all variations of the base model and the change in critical buckling load is discussed. The displacements in the bridge deck are found to be the same for small angles of skewness. Starting from an angle of ± 13°, the location of the maximum deflection in the bridge deck shifts towards the ends of the bridge deck instead of being in the middle. This can be explained by the influence of the wind load acting on the arch structure combined with the direction of the horizontal resultants of the hanger forces. This can cause partial relaxation, thus ensuring a small uplift at the longitudinal girders of the bridge deck. This is also the cause for the higher displacements in the arch. The torsion effect in the arch results in a counter clockwise rotation of the arch. When performing a buckling analysis on the changing angle of skewness, it is found that this initially has only a small impact on the critical load factor.

The increase and spread of population between regions always have an impact on settlements, whereby settlements require a land while land in a city has many activities, and it is limited. This limited potential settlement lands greatly influence the direction of the population in finding a place to settle. This study aims to study on potential settlement land in Semarang City. The methods used are quantitative descriptive and spatial descriptive that consist of settlement land suitability analysis (overlaying and weighting), potential settlement land analysis (buffering, overlaying and weighting), population growth analysis, settlement carrying capacity analysis, and distribution of population analysis. The results showed that the most available sub-district of potential settlement land is Mijen Subdistrict, and the total potential land area in Semarang City is 7,006 Ha. The results of the potential land are the destination for the direction of population distribution for sub-districts that do not have potential settlement land. Among others, are spread in West Semarang District, Tugu District, Ngaliyan District, Mijen District, Gunung Pati District, Tembalang District, and Pedurungan District.

Published: February 2020

The extreme right hate speech propagated currently in Brazil addresses a broad social spectrum, from feminist movements to traditional communities. The academic community and higher education institutions are also targets, as they are identified as poles of democratic resistance. Specific hate speech towards academy in Brazil is the subject of this paper. The persecution of academic community and knowledge itself occurs through the discursive dispute especially on social networks, and thus in this analytical exercise, we looked up at Facebook’s largest bolsonarista’s group – the “Jair Bolsonaro Presidency Support Group”, which brings together 317,000 members. We analyzed the memetic discourse on the page, focusing memes that were published between April and June 2019, thematizing higher public education, and presenting a bimodal verb-visual composition. These criteria led to the collection of 115 memes analyzed with the support of a QDA package. Analysis reveals the disqualification of university institutions and their actors through ironies, negative associations including stereotypes, simplification of debate to the shallower. Students are often associated with nudity as immorality, professors of indoctrination and ridicule, protesters of ignorance, or bad character. Political debate is reduced to extreme left-right polarization, with the criminalization of the left.

Authors: KULETA KLEMENTYNA
Published: February 2020

A restrictive anti-abortion law is in force in Poland. However, many people terminate pregnancy in cases other than those specified in the Act. Public discourse on this subject is dominated by philosophical and legal issues, and it lacks the voices of those who terminated the pregnancy. Abortion is often presented as a sad necessity, as always difficult or traumatic. I conducted research on describing own abortion experiences by people from Facebook pro-choice groups. 99 respondents who had 102 abortions completed an anonymous online questionnaire. From the material of answers, I selected categories that were used to analyze the results of the study: positive emotions, negative emotions, pregnancy as a burden, good experience, difficulty experience, stigmatization, support. It turned out that the experiences of termination of pregnancy were diverse. Respondents, describing their experiences, discussed topics rarely present in the discourse, such as the fact that abortion can be a good experience.

Published: February 2020

In industrial automation, adaptability is a key feature that can enhance the degree of autonomy in a plant sparing engineering months and costs. With the introduction of the service oriented architecture in control automation, a topology model is required to identify the vicinity relationships between the devices. Nowadays, due to the absence of the coupling between logistic aspects and control logic, the topology models are manually constructed which consequently affects the autonomy of the procedures generation. In this contribution, we introduce a concept to couple the logistics model with the devices abilities to generate product flow paths and procedures considering adaptable conditions.
Lessons Learned from an ACT-Based Physician-Delivered Weight Loss Intervention: A Pilot RCT Demonstrates Limits to Feasibility
Authors: Frayn Mallory , Carrière Kimberly , Knäuper Bärbel
Published: February 2020

Background: Acceptance and Commitment Therapy (ACT) interventions have shown to be effective in facilitating weight loss for emotional eaters, however, the lack of accessibility of these interventions limits their impact. The present study aimed to increase the accessibility of an ACT intervention for emotional eaters through delivery by physicians.

Methods: This two-arm pilot randomized controlled trial tested the effectiveness and feasibility of a brief ACT intervention for emotional eaters compared with standard care at a weight loss clinic in Toronto, Canada. Primary outcomes were changes in weight and emotional eating. Treatment satisfaction was also assessed.

Results: Participants in neither condition lost weight. Both conditions displayed decreases in emotional eating, but no condition interaction was found. Both patients and physicians reported high treatment satisfaction with the ACT intervention. However, there were high attrition rates and variability in intervention completion times.

Conclusion: The ACT intervention led to reductions in emotional eating and was well received by patients and physicians alike. However, the present study identified high attrition as a limitation to the feasibility of this mode of intervention delivery. Future interventions may be more effectively delivered in primary care settings by encouraging further brevity and exploring delivery by other health professionals. Trial registration: ClinicalTrials.gov NCT03611829. Registered 26 July 2018. Retrospectively registered.

Published: February 2020

The multitude of neuronal subtypes and extensive interconnectivity of the mammalian brain presents a substantial challenge to those seeking to decipher its functions. While the molecular mechanisms of several neuronal functions remain poorly characterized, advances in next-generation sequencing (NGS) and gene-editing technology have begun to close this gap. The clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein (CRISPR-Cas) system has emerged as a powerful genetic tool capable of manipulating the genome of essentially any organism and cell type. This technology has advanced our understanding of complex neurologic diseases by enabling the rapid generation of novel, disease-relevantin vitroand transgenic animal models. In this review, we discuss recent developments in the rapidly accelerating field of CRISPR-mediated genome engineering. We begin with an overview of the canonical function of the CRISPR platform, followed by a functional review of its many adaptations, with an emphasis on its applications for genetic interrogation of the normal and diseased nervous system. Additionally, we discuss limitations of the CRISPR editing system and suggest how future modifications to existing platforms may advance our understanding of the brain.

Published: February 2020

Objectives: The aim of this study was to perform morphometric analysis of arterial conduits harvested by harmonic scalpel in coronary artery bypass grafting (CABG) patients.
Methods: From 100 CABG patients, 200 arterial conduits—100 radial arteries (RAs) and 100 left internal thoracic artery (LITAs)—were harvested. The patients had similar characteristics (mean age, sex ratio, comorbidities, etc.). We divided the patients into 2 groups according to harvesting technique. In group 1, a harmonic scalpel was used in 50 patients for harvesting arterial conduits (50 LITA and 50 RA). In group 2, conduits were harvested using low-voltage electrocautery. To prevent side effects of clipping, all conduits in both groups remained in perfused condition until anastomosis. A 10-mm length of conduit was cut for transmission electron microscopy investigation. We calculated duration of harvesting, blood flow changes, and histopathologic changes of the conduits according to a vessel scoring system.
Results: In the harmonic scalpel group, we detected pathologic findings—corruption of endothelial integrity, subendothelial damage, and endothelial pathology—in 5 specimens (10%) (3 LITA  [6%] and 2 RA [4%]). In group 2, pathologic findings were detected in 16 conduits (32%; 11 LITA, 22%, and 5 RA, 10%). Endothelial dissection, subendothelial disarrangement, cellular separation due to intercellular edema, and subadventitial hematoma were the main pathologic changes in the classic harvesting method. There was a significant difference between the groups (P = .001). Harvesting time of LITA was nearly similar in both groups: 26.9 ± 11.1 min (range 25-38) in group 1 and 21.3 ± 8.6 min (range 21-25) in group 2 (P = .049). RA harvesting time was significantly shorter with the harmonic scalpel technique (20.3 ± 3.9 versus 27.6 ± 5.4 min, P = .022). The blood flow of the conduits was similar, with no statistical difference for the 2 arterial conduits (LITA, P = .76; RA, P = .55).
Conclusion: In the learning curve period, the use of a harmonic scalpel is time consuming and presents some difficulties during the harvesting of conduits. According to our study results, however, the harmonic scalpel technique may be useful because of decreased pathology, including spasm. In our opinion, graft occlusion or thrombus as a life-threatening condition and endothelial dysfunction may decrease with the use of this alternative harvesting technique.
Assessment of Culprit Lesion of Optical Coherence Tomography in Patients With Acute Myocardial Infarction: a Case Report
Authors: Bae Han Joon
Published: February 2020

In general, patients with acute myocardial infarction (AMI) have severe stenosis secondary to a superimposed thrombus at the event. Optical coherence tomography (OCT) is a useful imaging tool for patients with AMI. This allows us to identify the site of ruptured plaque, erosion of fibrous cap, and characteristics of stenotic lesion. In this case, we present the difference of the ruptured cavity and obstructed lesion.

Objective: The role of glucose-insulin-potassium (GIK) infusion during cardiac surgery has held interest for so many years without a clear answer. The aim of this meta-analysis was to evaluate the effect of GIK therapy on outcomes in patients undergoing on-pump cardiac surgery.
Methods: A comprehensive online review was performed in The Web of Science, Embase, Medline, PubMed, and The Cochrane Library databases from 2000 to 2019. Eligible studies included randomized controlled trials (RCTs) that compared GIK treatment with placebo or standard care during on-pump cardiac surgery. Risk ratios (RR) were used for binary outcomes and mean difference (MD) was used for continuous variables; both with their 95% confidence intervals (CI).
Results: A total of 18 RCTs involving 2,131 patients met the inclusion criteria. Compared with the control group, the GIK treatment significantly reduced in-hospital mortality (RR = 0.56, 95% CI: 0.32–0.97; P = .04), postoperative myocardial infarctions (MI) (RR = 0.71, 95% CI: 0.56–0.91; P = .006), the use of inotropic support (RR = 0.53, 95% CI: 0.45–0.63; P < .00001), and length of stay in the intensive care unit (ICU) (MD = -0.33, 95% CI: -0.52–-0.14; P = .0007). Moreover, GIK treatment seemed to be associated with fewer postoperative atrial fibrillation (AF) (RR = 0.81, 95% CI: 0.64–1.03; P = .09).
Conclusions: In patients undergoing on-pump cardiac surgery, GIK infusion has a beneficial role in mortality during hospital stay and demonstrates superior efficacy versus standard care for reduction in postoperative MI, AF, ICU length of stay as well as inotropic agent requirements.

Published: February 2020

Оновлення змісту дошкільної освіти в умовах демократизації та духовного відро-дження українського суспільства актуалізує необхідність забезпечення сприятливих умов для соціального розвитку та самовдосконалення особистості, починаючи з дошкільного віку. Результати аналізу психолого-педагогічних досліджень дозволяють визначити напря¬ми соціалізації дитини дошкільного віку провідне місце, серед яких належить: 1) забез¬печенню адаптації дитини до соціального середовища, введення дитини в світ людських взаємин, формування у дітей відкритості до суспільства; 2) сприянню динаміці і розвитку самоусвідомлення, що дозволить дитині змінювати уявлення про себе і ставлення до себе у процесі життєдіяльності, формування готовності до сприймання соціальної інформації, виховання навичок соціальної поведінки; 3) формуванню в дитини життєвої позиції, допомога у самореалізації в суспільстві. Передусім це стосується виховання усвідомленого ставлення до себе як вільної самостійної особистості та до своїх обов’язків, що визначається зв’язками з іншими людьми, бажання пізнавати людей, робити добрі вчинки.
Суспільно-гуманітарні дисципліни у морських навчальних закладах як засіб реалізації соціокультурної складової освіти (1991-2019 рр.)

У статті проаналізовано суспільно-гуманітарні дисципліни у морських навчальних закладах як засіб реалізації соціокультурної складової освіти у 1991-2019 рр. Розглянуто нормативно-правову базу відповідно до якої регулювався перелік дисциплін та їх належність до нормативних чи вибіркових. З’ясовано, що у незалежній Україні важливим завданням була гуманітаризація освіти тому кількість суспільно-гуманітарних дисциплін почала збільшуватись. Так, у відповідності до Інструктивного листа міністерства освіти України №1/9-64 від 19.05.1993 р. “Про викладання соціально-гуманітарних дисциплін” у навчальні плани додавався ряд соціально-гуманітарних дисциплін. Охарактеризовано дані дисципліни на основі збережених у архіві навчальних програм Херсонської державної морської академії та Морського коледжу.

Published: February 2020

Стаття присвячена проблемам формування універсальних компетентностей майбутніх лікарів – патологоанатомів засобами художньої літератури. Автори наголошують на актуальності формування як спеціальних (специфічних, предметно-професійних) компетентностей, так і базових (провідних, ключових, універсальних). Універсальні компетентності студентів-майбутніх патологоанатомів включають особистісні якості й здібності, зокрема, ініціативність, здатність до налагодження професійної комунікації на засадах толерантності, уміння адаптуватись у нових нестандартних ситуаціях, готовність критично аналізувати та адекватно оцінювати результати професійної діяльності, вміння аргументувати особисту точку зору тощо. Наголошується, що завдяки ознайомленню майбутніх патологоанатомів із медичною проблематикою в різних жанрах художньої літератури, насамперед, сформованому образу лікаря, а також вивченню творчого доробку письменників-медиків відбувається формування уявлення про медичну професію, яка потребує усвідомлення максимальної відповідальності за свої дії, систематичного психологічного й фізичного навантаження, готовності вирішувати неординарні, нестандарті завдання. Художній опис хвороби та смерті в літературних творах яскраво доповнюють їх сюжетну лінію. Проаналізувавши твори М. Булгакова, В. Стефаника, М. Коцюбинського, О. Кобилянської, автори статті наголошують на необхідності використання творів художньої літератури в формуванні універсальних компетентностей студентів-майбутніх патологоанатомів.
