We describe a microscopic setup implementing phase imaging by digital holographic microscopy (DHM) and transport of intensity equation (TIE) methods, which allows the results of both measurements to be quantitatively compared for either live cell or static samples. Digital holographic microscopy is a well-established method that provides robust phase reconstructions, but requires a sophisticated interferometric imaging system. TIE, on the other hand, is directly compatible with bright-field microscopy, but is more susceptible to noise artifacts. We present results comparing DHM and TIE on a custom-built microscope system that allows both techniques to be used on the same cells in rapid succession, thus permitting the comparison of the accuracy of both methods.

Coherent-wake plasma emission induced by ultrashort mid-infrared laser pulses on a solid target is shown to give rise to high-brightness, high-order harmonic radiation, offering a promising source of attosecond pulses and a probe for ultrafast subrelativistic plasma dynamics. With 80-fs, 0.2-TW pulses of 3.9-μm radiation used as a driver, optical harmonics up to the 34th order are detected, with their spectra stretching from the mid-infrared region to the extreme ultraviolet region. The harmonic spectrum is found to be highly sensitive to the chirp of the driver. Particle-in-cell analysis of this effect suggests, in agreement with the generic scenario of coherent-wake emission, that optical harmonics are radiated as trains of extremely short, attosecond ultraviolet pulses with a pulse-to-pulse interval varying over the pulse train. A positive chirp of the driver pulse can partially compensate for this variation in the interpulse separation, allowing harmonics of the highest orders to be generated in the plasma emission spectrum.
Temporal Expression and Cellular Localization of PAPPA2 in the Developing Kidney of Rat
Authors: Kumar Vikash , Yang Chun , Cowley Allen W.
Published: January 2020

PAPPA2 is a metalloproteinase which cleaves insulin-like growth factor binding protein (IGFBP)-3 and IGFBP-5, and its role in pregnancy and postnatal growth is primarily studied. Using exclusion mapping, we reported a subcongenic (26-P) rat where a 0.71-Mbp region containing the pregnancy-associated plasma protein a2 ( Pappa2) allele of salt-insensitive Brown Norway (BN) was introgressed into Dahl saltsensitive (SS) genetic background, resulting in the reduction of salt sensitivity. Pappa2 was differentially expressed in the adult kidney of 26-P and SS rats. Here, the expression and cellular localization of Pappa2 in embryonic and postnatal kidneys of 26-P and SS rats were examined. Pappa2 mRNA expression was 5-fold higher in the embryonic kidney (day 20.5) of the 26-P rat compared with the SS rat. Pappa2 mRNA expression progressively increased with the development of kidney, reaching a peak at postnatal day 5 before trending downward in subsequent stages of development in both strains. At all tested time points, Pappa2 remained higher in the 26-P compared with the SS rat kidney. Immunohistochemistry studies localized PAPPA2 in the ureteric bud (UB) and distal part of S-shaped body. PAPPA2 was colocalized with IGFBP-5 in the UB and Na+/K+/2Cl− cotransporter–stained tubules, respectively. Future studies are needed to determine the role of Pappa2 in kidney development and mechanistic pathways involved in this process.

Authors: Lenchenko Ekaterina , Blumenkrants Dmitry , Sachivkina Nadezhda , Shadrova Nadezhda , Ibragimova Alfia
Published: January 2020

Background and Aim: The study of biofilm-forming ability of Gram-negative microflora has great practical importance for assessing the effectiveness of antibiotic therapy and finding new ways to diagnose and inhibit the growth of biofilms. This is because poor penetration of antibacterial drugs into the biofilm can lead to the selection of resistant strains and has a consequence evident by the occurrence of relapse of infection in animals. This study aimed to evaluate morphological and densitometric indicators of biofilm formation as well as adhesive properties of Klebsiella pneumoniae.

Materials and Methods: K. pneumoniae was cultured at 37°C for 2-144 h in vitro. The specimens for optical microscopy were prepared by fixation with a 1:1 alcohol-ether mixture for 10 min and stained with a 0.5% solution of gentian violet for 2 min, and the optical density index was evaluated at a wavelength of 490 nm. Further, the adhesive properties of the microorganisms were determined at a concentration of 1 billion/ml and a suspension of ram erythrocytes at a concentration of 100 million/ml when cultured at 37°C for 24 h. Blood smears were prepared and stained with 0.5% gentian violet.

Results: K. pneumonia cultured at 37°C after 24 h on the meat peptone agar formed large, convex, mucous, and white colonies (d=3.0-6.0 mm). With the growth in the meat and peptone broth, uniform turbidity of the medium was observed. Analyzing the optical density indices (density, D), it was found that K. pneumoniae were good producers of biofilms (D=0.528±0.31). Data for indicators of adhesive properties of K. pneumoniae were as follows: Average adhesion index, 4.56±0.14; adhesion coefficient, 1.07±0.52; and adhesion index, 4.26±0.07. The studied bacteria had high adhesive activity. A direct correlation dependence (R=0.94) of the optical density of biofilms (D≥0.514-0.551) and AAI (4.15±0.28-4.76±0.75) was established.

Conclusion: This study has demonstrated that K. pneumoniae had high adhesive activity, was strong producer of biofilms, and the optical density of the sample exceeded the optical density of the control by more than 4 times.
Potret Dakwah Kontroversial Tayangan Televisi
Authors: Zamroni Muhammad
Published: January 2020

Salah satu tayangan Televisi bermuatan dakwah kontroversial adalah program acara Khazanah berdasarkan substansi, sistem pengemasan, dan jam tayang diproduksi oleh stasiun Trans7.Secara substansi dan tema lebih mengedepankan sisi kelompok masyarakat yang tidak suka tanpa memberikan ruang buat kelompok yang senang mengamalkannya. Padahal mereka tentulah juga  memiliki dalil dan argument yang kuat. Ujung-ujungnya bisa menggiring pada pembodohan masyarakat dan menjurus kearah konflik. Dalam pengemasan program acara Khazanah juga dianggap sudah baik, hanya saja gambar-gambar (feature) hanya diambil dari youtube bukan langsung produksi sendiri terkesan hanya dicocok-cocokkan. Durasi yang relatif tidak lama, yakni 30 menit adalah cukup, sehingga tidak membosankan.Respon khalayak NU, Muhammadiyah dan Syi’ah dengan jam tayang program acara Khazanah di Trans7 yang disiarkan mulai jam 05.30 sampai dengan jam 06.00 adalah prime time ditanggapi berbeda-beda. Paling tidak tercatat ada empat (4) episode yang dianggap kontroversial yaitu pertama, edisi 14 November 2012 menyalahkan praktek ziarah kubur yang dilakukan oleh mayoritas umat Islam Indonesia sebagai perbuatan syirik; Kedua, pada edisi 02 April 2013 menyalahkan praktek doa dan tawasul; Ketiga, edisi 04 April 2013 menyalahkan ajaran Ulama dan Kyai aliran (faham) Ahlussunnah wal Jamaah serta menyudutkan sosok seorang kyai sebagai sosok pelaku syirik; dan Keempat, edisi 31 Oktober 2013 berjudul mengenal Syiah.
Metode Pendidikan Anak Berbasis Qishshah AL-Anbiyâ’ dan Kontekstualisasinya di Perguruan Tinggi Islam

Published: January 2020

The purpose of this paper is to make the children's stories of the Prophets in the Koran as a basic method of child education. The background of the lack of studies in children's education that makes the Koran as the basis for the development of education and learning theory. In addition, the College of Religious Islam is supposed to close by the Koran thus many choose Western- secular theory . The theory used in this paper is a story in the Quran and learning methodologies . Using data from the literature and discourse analysis, this paper found that the prophetic method of educating children in the Koran are prenatally using monologues and after birth using the method of dialogue with intuitive engineering - shar'ī , case studies , emotive and scientific debate.Tujuan tulisan ini adalah menjadikan kisah-kisah anak para Nabi dalam Alquran sebagai dasar metode pendidikan anak. Ini dilatarbelakangi dari minimnya kajian dalam pendidikan anak yang menjadikan Alquran sebagai dasar pengembangan teori pendidikan dan pembelajaran. Selain itu, Perguruan Tinggi Keagamaan Islam yang seharusnya dekat dengan Alquran justru banyak memilih teori Barat-sekuler. Teori yang digunakan dalam tulisan ini adalah qashâsh al-qur’ân dan metodologi pembelajaran. Dengan menggunakan data pustaka dan analisis wacana tulisan ini menemukan bahwa metode kenabian dalam mendidik anak dalam Alquran adalah sebelum lahir menggunakan metode monolog dan setelah lahir menggunakan metode dialog dengan teknik intuitif-syar‘i, studi kasus, emotif dan debat ilmiah.

BEHAVIOR OF FULLY ENCASED COLD FORMED STEEL JOISTS WITH/WITHOUT WEB OPENINGS: EXPERIMENTAL INVESTIGATION
Authors: Elkhansa Hanadi , Masri Adnan , Abou Saleh Zaher
Published: January 2020

This paper presents an experimental investigation on the behavior of encased light cold-formed steel joists with/without web openings. The study is carried on two sets of composite beams constructed of cold-formed steel joists using I-beam built-up sections. The first set has no web openings while the second set has circular web openings. Each set consists of three beams with various steel section-concrete reinforcing ratio. The constant parameters included in this study are the cross sectional area of the specimen, distribution of web openings in the encased steel I-joist, and the compressive strength of concrete. The tests have been conducted by applying two concentrated identical loads. Consequently, a comparative study is carried out to compare between the behavior of specimens within one set, and a comparison between the specimens of the two sets. This comparison is related to strength, stiffness, ductility, energy absorption capacity and failure modes. Based on the testing results, it is concluded that, the load capacity of the composite beams without web openings is greater than that with web openings for the same steel ratio. But the existence of web openings in the encased steel joists enhances the ductility and the energy absorption of the composite beams. Also using cold formed steel I-joists in the composite beams allow the failure mode to be ductile flexural failure.

Authors: Vacanas Yiannis , Danezis Chris
Published: January 2020

The main objectives of this paper are to determine the main causes of delays that occur in construction projects in Cyprus and their effects, and suggest measures that can assist in their effective control and reduction. Seeing that no relevant work has been undertaken for the case of Cyprus, a detailed literature review was carried out to identify the most significant causes of delay at the international level. Based on the review, a survey questionnaire was distributed to members of the construction industry of Cyprus. The analysis of the results indicated variations requested by the client, mistakes and missing information from consultants’ drawings, and low productivity and inadequate programming of works from the contractor’s side to be the main causes of delay. By considering the delay causes analysis specific mitigation measures are proposed that are mainly related to the programming of the works, work progress and productivity monitoring, and the appointment process of the parties involved in a construction project.
EFFECT OF GRADATION AND REPLACEMENT LEVEL ON ALKALI-SILICA REACTIVITY OF MINERAL FILLERS
Authors: Sinno Noura , Shehata Medhat
Published: January 2020

Mineral fillers are used in concrete for a number of reasons, which include achieving self-consolidation properties. Different fillers are available depending on the type of the original rock. Alkali-silica reaction might occur if the filler is produced from a reactive rock. The present research focuses on evaluating the applicability of the current accelerated mortar bar test, described in ASTM C1260 and CSA A23.2-25A, in evaluating their reactivity. Three different fillers are used: a calcium-carbonate filler, a carbonate silica filler with 27% SiO2, and a siliceous filler produced from reactive aggregate. Two different gradations of the filler obtained from reactive aggregate are tested: 1) Gradation finer than 75 µm; 2) Gradation with 30% passing 150 µm sieve but is retained on 75 µm sieve and remaining 70% passing 75 µm. Results showed that the calcium-carbonate filler and the carbonate silica filler did not show any expansion higher than the non-reactive sand, while the filler obtained from reactive aggregate did not show expansion higher than the control at 14 days for both gradations, with the expansion showing at later age. This might be due to the high surface area of fillers and the reduced permeability affecting the rate of expansion. Hence, the need to extend the testing period beyond the 14-day specified in the standard to be able to see the expansion.

Published: January 2020

Real-time progress tracking of construction activities is critical for successful project monitoring and control. As such, the application of modern information technologies for progress tracking are proclaimed to overcome the limitations of manual approaches and hence contribute to the automated acquisition of onsite data for the computation of the earned value of progressed work. To this end, this paper presents a thorough review of 111 studies dealing with automated data collection and progress tracking on construction sites. The researched technologies were classified into four categories, namely: information technology, geo-spatial, imaging, and augmented reality (AR). It was found that research dealing with progress tracking using imaging technologies has been speedily growing over the years. The findings also revealed that the highest frequency (57) of reported technologies is found to be related to the AR category, with 74 percent of these studies having been published in the last eight years. Moreover, 63 percent of the studies were concerned with all kinds of project activities, with more specific areas of application reported to include concrete and steel elements, MEP elements, indoor and outdoor elements. The encountered technologies are reported to decrease labor hours and the time needed for progress monitoring, and automated data collection on construction activities progress is said to facilitate the generation of status reports and permit the early detection of deviations from the as-planned status.
INVESTIGATING SITE-RELATED NOTICES IN CONSTRUCTION CONTRACTS
Authors: Khalife Salam , Abdul-Malak Mohamed-Asem
Published: January 2020

Notices issued under the construction contract serve several purposes, the most significant of which is to facilitate the progression of the works. This is done through establishing necessary communications among the project participants by acting in accordance with the callings of the contract conditions. Through an in-depth examination of the notices stipulated under the standard conditions for the construction contract issued by the International Federation of Consulting Engineers (FIDIC), it was found that 43 out of 93 encountered notices deal with issues related to activities taking place on the construction site. The purpose of this paper is to present a detailed analysis of these notices and highlight their operability properties. The analysis focuses on the various characteristics pertaining to this vital group of notices, namely: their types, the participants involved in their administration, their related time bars, and the concerned aspects of the site activities. Results of the performed analysis are twofold: (1) the majority of these notices are found to be of the structured (complex composition) type; and (2) the contractor has the larger share in triggering their associated sub-clauses, and to do so, for the majority of these notices, within numerically stipulated time bars. The main contribution of the presented work is in providing a focused reference that can help contract administration practitioners, dealing with site-related matters, improve the current state of practice.
INVESTIGATING THE CIRCULAR ECONOMY AS A SOLUTION FOR CONSTRUCTION WASTE: CHALLENGES AND OPPORTUNITIES
Authors: El Asmar Lucien , Cho Namho , El Asmar Mounir
Published: January 2020

The construction industry results in a large amount of material waste, most of which currently ends up in landfills. This study aims to find new ways to reuse waste materials captured as outputs of construction projects. First, the circular economy (CE) concept is explored. Second, the application of CE as a potential solution for minimizing material waste on construction projects is investigated. To achieve a healthy industrial metabolism, the paper illustrates how a complex industrial ecosystem is one that produces little or no waste and whose constituents can be interdependent. Output ratios from the construction industry are compared with previous literature on material waste, as a foundation to present a cycle of material reuse. Reformulating the traditional input-output system into a more circular concept presents a set of challenges; however, the opportunities and significant impacts to the material cycles and landfills have proven beneficial and some major cities are starting to employ this concept with great success.
NONLINEAR FINITE ELEMENT ANALYSIS OF TRANSVERSELY PRESTRESSED CONCRETE DECK SLABS
Authors: Amir Sana , van der Veen Cor , de Boer Ane
Published: January 2020

This paper describes the modeling and analysis procedure of a 3D, solid, nonlinear finite element (FE) model of a bridge developed in the finite element analysis software package TNO DIANA to study the structural behavior in punching shear of transversely prestressed concrete deck slabs cast between flanges of long, pretensioned girders, and compressive membrane action. The numerical research was part of a broad project involving laboratory experiments carried out on a 1:2 scale model of such a bridge in Delft University of Technology. Both the experimental and numerical results showed much higher capacities than expected and this was attributed to the development of compressive membrane action in the plane of the slab. The numerical results were then compared with the experimentally found ultimate loads of eight basic test cases and it was discovered that the nonlinear FE models can predict the load carrying capacity quite accurately with a coefficient of variation of only 11%. It was concluded that punching shear failures can be reasonably modeled with non-linear finite element analysis of 3D solid models. Furthermore, using composed elements can lead to the determination of compressive membrane forces developed in a laterally restrained slab, which was previously difficult to determine using analytical techniques.
PRIORITIZING SIDEWALK UPGRADE PROJECTS TO MAXIMIZE COMPLIANCE WITH ACCESSIBILITY REQUIREMENTS
Authors: Halabya Ayman , El-Rayes Khaled
Published: January 2020

People with disabilities form 18.7% of the United States population, as reported by the U.S. Census Bureau in 2012. To avoid discrimination against this significant portion of the population, state and local governments are required by federal and state laws to provide and maintain accessibility for people with disabilities on their sidewalks and pedestrian facilities. To achieve compliance with these laws, state and local governments need to conduct self-evaluations to identify inaccessible pedestrian facilities and develop transition plans to schedule upgrade projects for these inaccessible pedestrian facilities. The federally-mandated transition plan requirements include the development of a schedule that displays, in detail, deadlines for all upgrade projects needed to achieve full compliance with accessibility requirements. To prepare this schedule, public entities are required to rank and prioritize pedestrian facilities upgrade projects. This paper presents the development of a novel methodology to quantify the impact of upgrading inaccessible pedestrian facilities on people with disabilities. The developed methodology considers several factors related to pedestrian facilities’ conditions and location to estimate the number of expected pedestrians with disabilities impacted by upgrading each inaccessible pedestrian facility. This methodology is designed to assist decision makers in state and local governments in the process of ranking and prioritizing inaccessible pedestrian facilities upgrade projects.
RESPONSIBLE DELIVERY OF THE BUILT PROJECT: WHOSE RESPONSIBILITY IS IT?
Authors: Kalach Mayssa , Abdul-Malak Mohamed-Asem , Srour Issam
Published: January 2020

Several procurement approaches have evolved over the years to suit the delivery of the ever increasing complexity and size of construction projects, coupled with the increasing pressure to embrace green methodologies as part of any such approach. Many of these available approaches reflect various levels of integration that may be desired to achieve in respect of critical project aspects, including: design, construction, operation, and finance. Decisions as to the most suitable delivery approach are to be made by project owners/developers, while being often assisted by market analysts, project management professionals, and other specialty consultants. While it is established that such a decision-making process does not follow an exact science, this paper tackles the issue of where responsibility truly rests for ensuring that the preferred or adopted project procurement strategy is consciously argued for with the interests of all involved stakeholders in mind. It touches on (1) the roles of the public and development policies and regulations prevailing in the locality of the intended project as well as (2) the capabilities and readiness of concerned project participants in enforcing, or at least, promoting more environmental, social, and economic consciousness into the procurement approach decision-making process.

Authors: Al Rawi Youmn , Temsah Yehya , Ghanem Hassan , Jahami Ali , Elani Mohamad
Published: January 2020

Many research studies have been conducted on the effect of impact loading on structures, and design procedures were proposed for reinforced concrete (RC) slabs; however the availability of these studies and procedures are limited for prestressed slabs. The proposed research will examine, using numerical analysis, the impact of rock fall on prestressed concrete slabs with equivalent moment capacity reinforced concrete slabs. It is expected that prestressed concrete slabs will have different behavior to resist impact loading compared with traditional reinforced concrete slabs. The thickness of the prestressed concrete slab will be 25cm whereas that of the reinforced concrete slab will be 30cm. The impact loading consists of 500Kg drop weight. The drop height will be 10m, 15m and 20m.The structural analysis is performed using a Finite Element program "ABAQUS". A comparison will be done between both slab types in terms of failure mode, damage, and deflection. It has been found that both slabs failed in punching. However, the RC slab performed better than the prestressed concrete slab with respect to the value of the deflection at mid-span, while both showed punching shear mode of failure.
THE IMPACT OF POSTS ON INTEREST IN A DEPARTMENT OF CONSTRUCTION MANAGEMENT FACEBOOK PAGE
Authors: Smallwood John
Published: January 2020

Universities, and units within, use social media to communicate with their respective publics, for varying reasons, namely to promote interest in a page and the related 'owner', to promote events and opportunities, to 'educate', and create awareness. Experience and anecdotal evidence indicate that visitors to Facebook pages find certain posts more interesting than others, which reality administrators of Facebook pages must contend with. The purpose of the study reported on is to determine the impact of a series of posts to determine, which attract the most interest. The research method can best be described as experimental in that posts pertaining to different subjects were undertaken periodically. Posts were constrained to construction, tertiary construction management education, and related issues such as conferences. The salient findings include that graduation publicity in the form of photos, predominates, followed by project related photos, and events in the form of conferences, presentations, and summits in terms of interest. Based upon the findings it can be concluded that certain posts are of greater interest than others. It is recommended that Facebook page statistics be regularly reviewed to determine the impact and relevance of posts. Facebook page administrators must evolve a 'cocktail' of posts to optimize the impact of their pages, which includes promoting interest in a page and the related 'owner'.

THE EFFECT OF DIFFERENT MOTOR ACTIVITIES AT PE LESSONS ON MYOPIA PROGRESSION
Authors: Kodaneva L , Ratkina N
Published: January 2020

Aim. The article deals with assessing the effect of different types of motor activity performed during physical education classes on myopia development. Materials and methods. 42 female university students aged 18 years participated in the study. All participants are characterized by acquired uncomplicated myopia. Three homogenous groups of fourteen were formed. The first group performed Nordic walking at PE classes, the second group used a fitness game (Just Dance), the third group was exempted from attending practical PE classes. All female students underwent an ophthalmic examination at the beginning and at the end of the study. The level of physical development and functional abilities of the body was established in all participants. The assessment was conducted based on the dynamics of indicators. Results. It was established that Nordic walking and lessons with a fitness game (Just Dance) did not influence significantly myopia development (р > 0.05). In the first group, myopia development was registered at the level of 0.34 diopter/year, and in the second group – 0.31 diopter/year. However, the comparison of the data obtained with those of the third group revealed a statistically significant difference (р < 0.01). Myopia development in the group exempted from attending practical PE classes was 0.75 diopter/year. Positive dynamics in motor coordination was registered in 57.1% of the first group and 64.3% of the second group. The majority of people from these groups demonstrated an increase in the indicators of the muscular strength of the leading arm and chest excursion. Moreover, more significant changes were registered for the group with a fitness game (Just Dance). The indicators of the third group remained at the same level or even worsened. Conclusion. Different types of motor activity at PE classes reduce  myopia development approximately in the same way. A negative dynamics reveled for certain indicators in the third group can be probably determined by the deficit of motor activity due to huge academic load.
PHYSICAL ACTIVITY ATTENUATES THE EFFECT OF THE FTO T/A POLYMORPHISM ON OBESITY-RELATED PHENOTYPES IN ADULT RUSSIAN MALES
Authors: Bondareva E , Popova E , Ketlerova E , Kodaneva L , Otgon G
Published: January 2020

Introduction. Although the effect of the fat mass and obesity-associated (FTO) gene on adiposity is well established, there is a lack of evidence whether physical activity (PA) modifies the effect of FTO variants on obesity in Russians. Therefore, the purpose of this study was to examine PA influences and interactive effects between FTO variants and PA on measures of adiposity in Russians. Materials and methods. 110 Russian males aged 22–52 years old were examined. Anthropometry: height and weight, waist and hip circumferences were taken. The whole-body impedance was measured on the right-hand side of the body using the bio­impedance meter ABC-01 ‘Medas’ (SRC Medas, Russia) according to a conventional tetrapolar scheme at a frequency of 50 kHz. For each subject participating in the study, the genotype was determined by the polymorphic systems of the T/A (rs9939609) polymorphism of the FTO gene (Lytekh, Moscow). Results. Participants who did not engage in regular PA exhibited higher BMI, fat mass, HC, and WC with statistical significance (P ≤ 0.01). Although significant asso­ciations between the three FTO genotypes and adiposity measures were found in the sedentary group. There were no significant associations between FTO genotypes and obesity-related phenotypes in the PA group. Conclusion. Comparison of morphological parameters in carriers of alternative genotypes in two subgroups with different lifestyles makes it possible to conclude that the A allele determines a greater tendency to accumulate fat in cases where there is no regular physical activity.
DEPENDENCE OF HUMAN RESILIENCE ON THE FEATURES OF TEMPERAMENT AND CONTROL OF BEHAVIOR
Authors: Laktionova Anna Igorevna
Published: January 2020

Abstract. The article considers "human resilience" as a meta-ability. The difficulty of comparing research results due to various psychological approaches and methods is noted. The necessity of studying not only the socio-psychological and psychological levels of human resilience, but also its psychophysiological level is substantiated. The author offers a level and component structure of human resilience. The data of an empirical study are presented aimed at studying the conditionality of human resilience by the features of temperament and control of behavior. The control of behavior is considered the ability for voluntary and conscious self-regulation, emotional intelligence and coping mechanisms determined by cognitive, emotional and volitional abilities. Materials and methods. The following methods were used: Self-regulation profile questionnaire, J. Strelau Pavlovian Temperament Survey (PTS), Ways of Coping Questionnaire (OSS – WCQ), EmIn emotional intelligence questionnaire, Resilience Research Center Adult Resilience Measure (RRC-ARM). Results. As a result of multiple regression analysis of the data, crucial individual characteristics of resilience (within the considered components) were identified. These include: “General level of emotional intelligence”, “Balance of nervous processes”, “Search for social support” as a coping strategy and “Planning” as a mechanism of subjective self-regulation. It is shown that emotional intelligence, the ability to seek help from other people and independently set life goals can be developed through education and psychotherapy.

Abstract. Considering research on rehabilitation and rehabilitation potential in modern medical and psychological literature from the leading databases reduces subjectivity when analyzing the relevance of scientific issues. The results obtained will allow predicting the further advancement of scientific knowledge on rehabilitation and rehabilitation potential. Materials and methods. The criterion for inclusion in the review was scientific data published in peer-reviewed scientific journals and lack of repetition of data from the same scientific papers by the same authors. Results. When searching for the word “rehabilitation” over the past 10 years, 3685 works were found in the Web of Science database, and 36332 publications were found in the eLibrary national database. A search for the keyword “rehabilitation potential” in the Web of Science database using inclusion/exclusion criteria revealed 3569 published works while a comparable search query in the domestic database identified 786 works. When comparing the Web of Science and eLibrary databases, similarities and differences were revealed in relation to the use of the concepts of “rehabilitation” and “rehabilitation potential”. The “Neurology” direction occupies a leading position in both databases, “Rehabilitation” as a separate direction is mostly studied abroad, and psychological assistance closes the top three in the Web of Science database. Mental health rehabilitation issues are more commonly presented in eLibrary. Conclusion. The development and publication of studies on rehabilitation potential is more active when it comes to patient-oriented or non-medical models of rehabilitation. Verification of this assumption may be the subject of further research.

Published: January 2020

Abstract. The success of students' adaptation to the educational process depends on individual psychophysiological features, which are manifested in the behavioral strategy. Materials and methods. The study involved 76 young males and 132 females, the average age was 21.6 ± 0.2 years. Evaluation of the behavioral strategy in conflict interaction was carried out using the method of K. Thomas; the structure of aggression was studied with the help of the A. Buss and A. Durkee hostility inventory; the level of reactive and personal anxiety was measured with Spielberger state trait anxiety inventory (Spilberger-Khanin test). The neurodynamic properties were evaluated using the results obtained in the “Simple visual-motor reaction” and “Choice reaction” test. Mathematical processing of the results was carried out using Statistiсa 6.0. The compliance of the data with the normal distribution was checked by the Kolmogorov-Smirnov criterion. Differences were considered significant at p ≤ 0.05. Results. Tuvan students revealed gender differences in behavior in conflict situations: female students mostly demonstrated an effective behavioral strategy, while male students were characterized by an ineffective behavioral strategy. Female students with a neutral behavioral strategy (16.7%) were characterized by high indices of aggressiveness and hostility and low values of reactive anxiety. A high level of personal anxiety was found in all female students regardless of their behavioral strategy. Male students with high values of aggressiveness, reactive and personal anxiety were identified in isolated cases in a group with an effective behavioral strategy. In female students, the latent period of a simple visual-motor reaction was associated with a behavioral strategy. In male students, differences in the latent period of a simple visual-motor reaction were not detected regardless of the strategies of behavior. The functional level of the central nervous system of all the students studied, regardless of the strategy of behavior, was characterized as "slightly reduced." According to the data obtained for the “stability of the nervous reaction” and “level of functionality”, gender differences were revealed. Conclusion. Neurodynamic features, the prevailing effective strategy of behavior in a conflict situation, and the structure of aggression of Tuvan female students indicate an adequate reactivity of the body, which is confirmed by a “slightly reduced” level of performance. This, probably, provides a more successful adaptation to the educational process compared to male students.

Published: January 2020

Bu çalışma gençlerin ileri teknolojiye dayalı ürün ve hizmetleri kullanmalarına etki eden faktörleri belirlemeyi hedeflemektedir. Bilişsel (ileri teknolojiye dair inançlar), psikografık, demografik ve dışsal (olumlu-olumsuz) faktörler test edilmiştir. Bilişsel faktörlerin ölçülmesinde Parasuraman ve Colby’mn (2001) Teknolojiye Uyum îndeksi-TUİ (Technology readiııess index -TRI) baz alınmıştır. Örneklem Ankara Üniversitesi ve Mustafa Kemal Üniversitesinde okuyan 344 işletme bölümü öğrencisini kapsamaktadır. İleri teknolojiye dayalı ürün ve hizmetlerin kullanım düzeyini pozitif etkileyen faktörler “Teknolojiye uyum düzeyi” ve “Yeniliğe açık olmayı ifade eden psikografik eğilimler” olarak saptanmıştır. Ayrıca, gelir düzeyi arttıkça ileri teknolojiye dayalı ürün ve hizmetleri kullanım düzeyi artmaktadır. Erkekler teknolojiyi daha fazla kullanmaktadırlar. İş yaparken zaman sınırının olmaması ve çağı yakalama isteği ürün ve hizmetlerin kullanım düzeyini arttırmaktadır. İşletmenin ürün ile ilgili bilgilendirme yetersizliği ve tüketicilerin alışveriş yaparken gezme olanağının bulunmaması kullanım düzeyini azaltmaktadır. Bulgular ışığında pazarlama yöneticilerinin strateji belirlerken dikkate alması gereken önemli noktalar ve öneriler ortaya konmaktadır.

Published: January 2020

21. yüzyılda yeni dünya düzeni, eski alışkanlıkların yerini almaktadır. Dünya giderek globalleşmekte, bilinen ülke sınırları ekonomik faaliyetler açısından ortadan kalkmakta ve sonuç olarak meydana gelen gelişmeler eskisine oranla çok daha büyük bir boyutta etki yaratmaktadır. İşletmeler ise tüm bu değişim ve gelişim dalgasına ayak uydurmak ve hayatta kalabilmek için mücadele etmek zorundadır. Ancak giderek daha da küçülen dünyada, artan rekabet baskısının da etkisiyle mücadele gücünü bulabilmek ve uzun yıllar hayatta kalabilmek o kadar kolay değildir. İşletmeler mutlak suretle yeni rekabet alanları bulmak ya da sahip oldukları alanda rekabet avantajı yaratmak zorundadır. İşte bu noktada, işletmelere rekabet avantajı sağlayacak en önemli yönetim uygulamalarından biri de marka yönetimidir. Bu çalışmada özellikle son yıllarda artan rekabet yarışında üstünlük sağlayabilmek için gerçekleştirilmesi gereken marka yönetimi uygulamasına değinilmiş ve mobil-telekomünikasyon sektörünün önde gelen işletmelerinden birinde yer alan marka yönetimi uygulaması açıklanmaya çalışılmıştır.
