Parent assessment of medical student skills in ambulatory pediatrics
Authors: Persson Erika , Haines Christina , Lang Mia
Published: April 2020

Background: Partnership with parents is a vital part of pediatric medical education, yet few studies have examined parent attitudes towards learners in pediatric settings. Methods: Questionnaires were used to determine parent and student assessment of professional and clinical skills (primary outcome) and parent attitudes towards 3rd year medical students (secondary outcome) at the University of Alberta. Chi Square, Kendall’s Tau and Kappa coefficients were calculated to compare parent and student responses in 8 areas: communication, respect, knowledge, listening, history taking, physical examination, supervision, and overall satisfaction. Results: Overall satisfaction with medical student involvement by parents was high: 56.7% of all parents ranked the encounter as ‘excellent’. Areas of lesser satisfaction included physician supervision of students. Compared to the parent assessment, students tended to underrate many of their skills, including communication, history taking and physical exam. There was no relationship between parent demographics and their attitude to rating any of the students’ skills. Conclusions: Parents were satisfied with medical student involvement in the care of their children. Areas identified for improvement included increased supervision of students in both history taking and physical examination. This is one of the largest studies examining parent attitudes towards pediatric students. The results may enhance undergraduate curriculum development and teaching in pediatric ambulatory clinics and strengthen the ongoing partnership between the community and teaching clinics.

Authors: Mrazek Jan
Published: April 2020

The article focuses on the issue of congested roads in cities. The problems of heavy traffic both large and smaller towns. Some towns in the Czech Republic do not have built bypasses and so there is a heavy traffic congestion at favorite times. Road transport has become one of the most popular forms of transport. This trend is unlikely to change in the near future. The current market offers dynamic traffic management but not with the appropriate effect. Our proposed method belongs to dynamic traffic control based on real traffic control. The proposed method works in real time with the light signaling device behind the monitoring sections. The function of the proposed method is to extend the free passage of the light-signaling device.

Internet of Things (IoT) for Smart Precision Agriculture
Authors: Alhasnawi Bilal , Jasim Basil , Issa Bayadir
Published: April 2020

The scarcity of clean water resources around the globe has generated a need for their optimum utilization. Internet of Things (IoT) solutions, based on the application-specific sensors’ data acquisition and intelligent processing, are bridging the gaps between the cyber and physical worlds. IoT based smart irrigation management systems can help in achieving optimum water-resource utilization in the precision farming landscape. This paper presents an open-source technology-based smart system to predict the irrigation requirements of a field using the sensing of ground parameters like soil moisture, soil temperature, and environmental conditions along with the weather forecast data from the Internet. The sensing nodes, involved in the ground and environmental sensing, consider soil moisture, air temperature, and relative humidity of the crop field. This mainly focused on wastage of water, which is a major concern of the modern era. It is also time-saving, allows a user to monitor environmental data for agriculture using a web browser and Email, cost-effectiveness, environmental protection, low maintenance and operating cost and efficient irrigation service. The proposed system is made up of two parts: hardware and software. The hardware consists of a Base Station Unit (BSU) and several Terminal Nodes (TNs). The software is made up of the programming of the Wi-Fi network and the system protocol. In this paper, an MQTT (Message Queue Telemetry Transportation) broker was built on the BSU and TU board.
IMPACT OF EXCHANGE RATE DERIVATIVES ON STOCKS IN EMERGING MARKETS
Authors: Bernal-Ponce L. Arturo , Castillo-Ramírez Claudia Estrella , Venegas-Martínez Francisco
Published: April 2020

This paper investigates the effect of derivatives on the relationship between the foreign exchange rate and the stock market. A theoretical model is used to extend the understanding of that relationship. Also, the model is tested with an empirical analysis using the GMM strategy for the Mexican and Brazilian stock markets for the period 2007 to 2019. Findings reveal that in addition to the spot exchange rate, exchange rate futures explain the currency exposure, wherein the derivative effect is the most prominent. The result implies that both risk sources should be considered in the implementation of risk management or macroeconomic policy. The theoretical results are extended by applying them to international portfolio management, proposing a strategy to mitigate foreign exchange exposure with derivatives. This study contributes to the literature by explaining why the minimum variance hedge ratio plays an essential role in the foreign exchange rate and stock market nexus.
A Random Forest Approach to Identifying Young Stellar Object Candidates in the Lupus Star-forming Region
Authors: Melton Elizabeth
Published: April 2020

The identification and characterization of stellar members within a star-forming region are critical to many aspects of star formation, including formalization of the initial mass function, circumstellar disk evolution, and star formation history. Previous surveys of the Lupus star-forming region have identified members through infrared excess and accretion signatures. We use machine learning to identify new candidate members of Lupus based on surveys from two space-based observatories: ESA’s Gaia and NASA’s Spitzer. Astrometric measurements from Gaia's Data Release 2 and astrometric and photometric data from the Infrared Array Camera on the Spitzer Space Telescope, as well as from other surveys, are compiled into a catalog for the random forest (RF) classifier. The RF classifiers are tested to find the best features, membership list, non-membership identification scheme, imputation method, training set class weighting, and method of dealing with class imbalance within the data. We list 27 candidate members of the Lupus star-forming region for spectroscopic follow-up. Most of the candidates lie in Clouds V and VI, where only one confirmed member of Lupus was previously known. These clouds likely represent a slightly older population of star formation.

Calanthe sieboldopsis, a new species, is here described and illustrated from Luoxiao Mountains, Jiangxi Province, eastern China. It is morphologically similar to C. sieboldii Decne. ex Regel, but differs from the latter in having smaller flowers, longer spurs, rectangular mid-lobes with emarginate apex (vs. elliptic mid-lobes with mucronate apex), disc with 3 ridges and the proximal ends of the lateral 2 ridges enlarged with light reddish spots and minute white hairs (vs. disc with 5 ridges and 2 rows of white short hairs at base) and pollinia equal in size (vs. unequal in size). A preliminary risk-of-extinction assessment, according to the IUCN Red List Categories and Criteria, is given for the new species.
Adnexal Masses in Adolescents
Authors: Northridge Jennifer L.
Published: April 2020

Adnexal masses in adolescents, such as functional cysts, are often benign and can usually be managed expectantly since they typically regress on their own. The most common ovarian neoplasm in adolescents is a benign cystic teratoma. Both functional cysts and benign cystic teratomas are associated with ovarian torsion. Of concern, ovarian torsion requires a high level of suspicion when adolescents present with acute abdominal pain, as almost one-half of cases have no associated adnexal masses. The most common malignant adnexal masses in this age group include germ cell tumors, followed by epithelial cell tumors. Finally, ectopic pregnancy and tubo-ovarian abscesses must be considered in the differential diagnosis of adnexal mass, as delays in treatment may seriously affect an adolescent's health and future fertility. Obtaining an accurate history, including a sexual history, requires reviewing this history with the adolescent privately. Management of adnexal mases should prioritize fertility preservation.

Published: April 2020

In this chapter, the authors present a new strategy for multi-attribute decision making in interval rough neutrosophic environment. They define Hamming distance and Euclidean distance between interval rough neutrosophic numbers. They also define interval rough neutrosophic relative positive ideal solution (IRNRPIS) and interval rough neutrosophic relative negative ideal solution (IRNRNIS). Then the ranking order of the alternatives is obtained by the technique for order preference by similarity to ideal solution (TOPSIS) strategy. Finally, a numerical example is provided to demonstrate the applicability and effectiveness of the proposed interval rough neutrosophic TOPSIS strategy.
Gender Mainstreaming in Development
Authors: Kurebwa Jeffrey
Published: April 2020

Gender mainstreaming means the consistent use of a gender perspective at all stages of the development and implementation of policies, plans, programmes, and projects. Mainstreaming gender differs from previous efforts to integrate women's concerns into government activities in that, rather than ‘adding on' a women's component to existing policies, plans, programmes, and projects, a gender perspective informs these at all stages and in every aspect of the decision-making process. Gender mainstreaming starts by analyzing the everyday life situation of women and men. It makes their differing needs and problems visible and examines what this means for specific policy areas. In this way, it ensures policies and practices are not based on incorrect assumptions and stereotypes. It recognizes that gender is one of the most fundamental organizing features in society and affects our lives from the moment we are born.

Published: April 2020

Trade unionism is a major part of modern workplaces. It forms the basis for peaceful relations and consensus building to attain mutual goals. At the heart of trade unionism is social justice and equality, which affirms the rights of all employees regardless of gender to enjoy freedom of association and accessibility, etc. Socio-cultural exigencies have made women to face tough challenges and discriminatory treatment at work, resulting in fewer rights and liberties and leading to economic and psychological stress. The World Bank noted that the starting point is the recognition that women are disadvantaged in most indicators at work—earnings, quality of employment, participation. Trade unions are central to protecting the interests of workers, and building strong unions can foster the elimination of discrimination at work. This chapter shall proffer actionable strategies and issue-based outlines that would advance the cause of gender equality, address the lopsided power configuration between the genders at work, and engender women's participation.

Published: April 2020

This research sought to examine whether NGOs working on gender are culturally sensitive in their programming. NGOs working on gender in Zimbabwe presented that they have an understanding of cultural sensitivity, but there is need to be more comprehensive ensuring stakeholder inclusion in programming. There is a need to create a rapport with all stakeholders both the external and internal to ensure programs' effectiveness. NGO programs should not challenge the existing cultural values, norms, and beliefs in rural communities, but instead, they should be catalysts for development, drawing their programs from cultures that exist in communities to foster development. The study recommends that NGOs should make use of the bottom-up approach to promote community participation and people programs to ensure program success and acceptability.
Crime or Human Right?
Authors: Arimoro Augustine Edobor
Published: April 2020

To the Nigerian state, consensual sexual activity among persons of the same sex is against the order of nature and must be punished as a crime. On the other hand, to persons who engage in sexual activity with persons of the same gender and to rights' activists, the act is a right, like any other, which should be respected and protected. This chapter examines the cultural issues, the human rights angle, and the future of the criminalization of same-sex sexual conduct conundrum in Nigeria. Using the doctrinal method of legal research methodology, the chapter reviews laws criminalizing homosexuality in Nigeria in juxtaposition with human rights provisions both in the international and domestic context in search of a solution to the problem. Accordingly, it is recommended that while the law should protect cultural values, human rights are sacrosanct and must not be sacrificed.
The Properties of Concrete Based on Steel Slag as a By-Product of Metallurgical Production
Authors: Martauz Pavel , Václavík Vojtěch , Cvopa Branislav
Published: April 2020

This article presents the results of research on the use of unstable steel slag with a fraction of 0/8 mm as a 100% substitute for natural aggregate in concrete production. Two types of cements were used for the production of concrete: Portland cement CEM I 42.5N and hybrid cement H-CEMENT. Both of these cements were produced by the company Považská cementárna, a.s., Ladce. The main objective of this study was to assess the suitable type of binder to be combined with unstable steel slag in the production of concrete composite. The prepared concrete was used to test the properties of a fresh concrete mix, i.e. its consistency and bulk density. Hardened concrete was used to test the strength and deformation properties, including cube strength after 3, 7, 14, 21, 28 and 90 days, as well as prism strength after 28 days. The static modulus of elasticity was determined using prisms after 28 days of age of the test specimens. Our attention was also focused on determining the class of leachability of the concretes based on steel slag with CEM I 42.5N and H-CEMENT. The durability of concrete prepared on the basis of steel slag was tested in an environment with increased temperature and pressure. The results of the strength characteristics tests show a difference between the 28-day average cube strength of concrete using CEM I 42.5N and H-CEMENT (34.6 MPa and 29.1 MPa), while after 90 days, the average cube strength value stabilized at about 38 MPa. The average values ​​of the static modulus of elasticity when using CEM I 42.5N and H-CEMENT are almost identical, achieving values ​​of 32.5 GPa and 32.8 GPa, respectively. Concrete based on steel slag with CEM I 42.5N and H-CEMENT can be included in leachability class IIb. The results of the durability test of concrete based on steel slag in an environment with increased temperature and pressure confirmed the use of H-CEMENT hybrid cement from the company Považská cementáren, a.s., Ladce, as a suitable binder. .

Published: April 2020

This work studied the potentials of indigenous Micrococcus sp., Bacillus sp., Pseudomonas sp., and Escherichia coli (E. coli) for bioremediation of lead contaminated soils collected from Amita forest in Ebonyi State of Nigeria.The organisms isolated from the soils were conditioned with the predetermined optimum factors in inoculated soil samples. The samples were tested for residual lead concentration at times 8, 16, 24, 32, 40, 48, and 56 days with Atomic Absorption Spectrophotometer.The performances of the organisms were in the decreasing order of Micrococcus sp., Bacillus sp., Pseudomonas sp., and E. coli. Micrococcus sp. and Bacillus sp. performed earlier at time 16 days as against Pseudomonas sp., and E. coli at 24 days. The maximum efficiencies were discovered at time 56 days as 76.68%, 72.24%, 70.11% and 55.47% for Micrococcus sp., Bacillus sp., Pseudomonas sp., and E. coli respectively with respective residual concentrations of 31.55 mg/kg, 37.55 mg/kg, 40.44 mg/kg and 60.24 mg/kg at the respective efficiencies.The rates of removals were in the decreasing order of -0.0524d-1 for Pseudomonas sp., -0.0714 d-1 for Bacillus sp., -0.0743d-1 Micrococcus sp., and 0.113 d-1 E. coli. The fitted models showed diffusion as the rate-limiting step for removals by Pseudomonas sp., Bacillus sp., and Micrococcus sp.; while chemisorption was the rate-limiting step for removal by E. coli. This information will be helpful to researchers and decision makers for the remediation of lead contaminated soils.

Authors: Kováč Marek , Sicakova Alena
Published: April 2020

This study introduces the experiment based on following parameters: kind of aggregate (natural river gravel and air-cooled blast furnace slag), the aggregate gradation and content of binder. Main properties such as compressive strength, void content and hydraulic conductivity of pervious concrete were investigated in the experiment. The experiment showed satisfactory results in the case of pervious concrete made of natural aggregate. Results of pervious concrete made of air-cooled blast furnace slag aggregates are perspective, however needs for some optimizations. Results confirmed the opposite relationship between compressive strength and void content/hydraulic activity. ACBFS performs worse than NA as for compressive strength, while it performs better in the case of hydraulic conductivity and void content.
Comparison of Degradation of Concretes with High Portions of Mineral Additions and Ordinary Portland Cement Based Concretes due to Simulated Acidic Rain
Authors: Eštoková Adriana , Harbuľáková Vlasta Ondrejka , Smolakova Michaela
Published: April 2020

The paper deals with investigation of changes in selected properties of concretes which have been exposed to acid rain. The experiments took place in laboratory under model solution representing acid rain (40 % HNO3, 60% H2SO4) over a period of 7 weeks. The concrete samples investigated were concretes with ordinary Portland cement only as well as concretes of high-portion-mineral-addition-cements as well. Disruptions, cracking and samples' falling apart at the end after 7-week exposure to acid rain were observed by evaluation of visual changes. Based on the determination of the other parameters the results are not so uniform that is why the clear statement of more suitable concrete resistant to acid rain is not given. The assumption that a high-mineral concrete mix would be more suitable for environments exposed to acidic rain was not confirmed in this experiment.
Ethical competence expressed in students’ written texts
Authors: Lilja Annika
Published: April 2020

Teaching ethics in compulsory school regained urgency some years ago in Sweden when National Tests in ethics were introduced. Students were evaluated as having or not having the ethics knowledge required. The aim of this study is to investigate what aspects of ethical competence students express in texts from National Tests, and to investigate what cultural tools 12- and 15-year-old students use in their texts about a given ethical situation. A qualitative content analysis was performed in three steps. In the first step, four aspects of ethical competence were identified: to verbalise, to take a stand, to take responsibility for one’s actions and an understanding of life. In the second step, the identified ethical competence was interpreted through four ethical voices building on the theories of Nussbaum, Løgstrup, Benhabib and Singer, showing that the students’ texts contain varying aspects of ethics. In the third step, cultural tools used by the students were identified. The conclusions were that (1) some ethical perspectives, such as the societal and global perspectives, are disadvantaged in the analysed texts, and accordingly in the tasks; (2), ethics is a difficult subject to assess in a fair way; and (3) since cultural tools are dependent on the social, cultural and historical context, the school has a responsibility to teach ethics in a way that gives all students the power and authority to live good lives.
A Critical Analysis of Medohara, Lekhana, and Karshana Plants from Nighantus
Authors: Kumar Vishal , Bidhuri Yashika , Nesari Tanuja , Sherkhane Rahul , Ghildiyal Shivani
Published: April 2020

Aim:

To compile and critically analyze the Medohara, Lekhana and Karshana drugs mentioned in Nighantus with special reference to the management of obesity with promising results.

Background:

Due to sedentary lifestyle and unwholesome food habits there is an ascending graph of obesity in India and worldwide. Although contemporary science has made efforts to cope up with this alarming rise but the results are not promising. Thus, the world is looking towards ancient healing science of Ayurveda to combat the situation. Ayurvedic classics and Nighantus are the wealth of herbal drugs and dosage forms. The drugs ascribed under the heading of Medohara, Lekhana and Karshana Dravyas in Ayurveda may have anti-obesity activity. The rational use of these time tested herbs may be the answer for the management of obesity. Earlier number of studies were carried out on anti-obesity drugs described in Brihat trayi. However, the data of anti-obesity drugs described in Nighantus is not available till date. Thus, the review was conducted by reviewing the popular available Nighantus i.e. Dhanvantari Nighantu (10th–13th Centuries), Sodhala Nighantu (12th century), Madanapala Nighantu (14th century), Kaiyadeva Nighantu (15th century), Bhavaprakasha Nighantu (16th century), Raj Nighantu (17th century) and Priya Nighantu (20th century).

Review results:

A total of 72 drugs were found having Medohara, Lekhana and Karshaniya effect in the Nighantus database.

Conclusion:

Pharmacodynamic attributes i.e. Rasa, Guna and Veerya have individual effect in obesity. Katu Vipaka is having more significant influence in producing Medohara, Lekhana and Karshana karma which is important for management of obesity.

Clinical significance:

These drugs can be validated for their anti-obesity or anti-hypolipidimic activities on the basis of preclinical and clinical studies. It will also help in selection of drugs for the management of obesity.
Capital Adequacy and Systemic Risk of Banks in India
Authors: Dash Mihir
Published: April 2020

This study examines the role of capital adequacy in systemic risk for banks in India. The moderator variables considered for the study include bank size, non-performing assets, leverage, deposits, loans & advances, and investments. A fixed-effects panel regression model was applied, with bank fixed effects and year fixed effects.The study contributes to the literature by proposing the concept of minimum level of capital adequacy for neutral systemic risk, which is the level of capital adequacy for which the systemic risk is non-positive. The results of the study indicate that bank size, non-performing assets, leverage, and loans & advances have a significant impact on the minimum capital adequacy for neutral systemic risk. Further, the results of the study suggest that the role of capital adequacy in systemic impact was different for public sector and private sector banks.The study suggests that, instead of setting a fixed capital adequacy level for all banks, the model can be used to set capital adequacy targets for individual banks with estimates or projections of the bank’s characteristics. This can be used in conjunction with the Basel III framework in order to rationalise capital adequacy targets.
Online Education as a Solution to Managing and Sustaining Foreign Aid: Comparison Between the European Cases and Others
Authors: Oh Jinhwan
Published: April 2020

Inbound education official development assistance (ODA) has been known to be spread across regions regardless of geographic proximity. This not only negatively impacts effectiveness to manage aid, but also to sustain aid long-term. This study examines aid disbursement pattern of the United Kingdom, Germany, Australia, and South Korea, which are all members of OECD’s Development Assistance Committee that allocates inbound education ODA. With the empirical results confirming Korea’s lack of concentration in education ODA, this study recommends establishing satellite campuses as a more viable, operative solution than the previously suggested solution of establishing a specialized agency focusing on scholarship programs. As validated by Nagoya University’s Asian Satellite Campuses Institute (ASCI), transferring much of work to the online platform reduces time and financial costs. Furthermore, satellite campuses are expected to facilitate various means of partnerships among aid donor countries that are implementing similar programs. International collaborative efforts could help improve the quality of inbound education and play an important role in attracting bright prospective students. Thus, donor countries could utilize online education platform to overcome severe geographic obstacles in distance education and increase effectiveness of its inbound education ODA.
The University as an Educational Institution With Values in the Knowledge Society
Authors: Gómez-Aguilella María-José
Published: April 2020

In this paper, we present a study which analyzes the relation between educational institution with the values of their students, all related with the knowledge society. The specific profile, young university students, help us to determine their prospects in the actual framework and beyond. The research is also focused on a specific country, Spain, although cross-cultural studies are being developed. The surveys were recruited through an online survey, the best way for our target to participate. We conduct a survey in which we elicited the importance of university like an educational institution regarding the knowledge society frame, as well as the values of their students depending on the election of the educational institution. This allows us to determine if the election of the educational institution is related with the values of their students, and if these values determine the election of the university. We try to establish by means of a quantitative study the profile of these students. For this reason, the study reveals knowledge of a new relations in specific variables, determined by the experience lived, which is an area of research that has received little attention to date. The variables to investigate are Knowledge society, educational institution and values (of their students) and its relation.
Transformation of a Grid of Quadrats to Cope With Perspective Artifacts
Authors: Cruz-Orive Luis Manuel , Cruz Marcos
Published: April 2020

The direct superimposition of a standard test grid of congruent quadrats onto an image bearing a population of particles exhibiting perspective artifacts, tends to increase the variance of the population size estimator, because the quadrat contents become unbalanced. If the quadrats are transformed according to the same projection mechanism affecting the particles, however, then the variance is restored into moderate values. Our purpose was to provide exact, easily programmable equations for the relevant transform.
TYPOLOGY OF TOURIST GUIDES AND ITS USE IN TITLES
Authors: Nowotarski Włodzimierz
Published: April 2020

Purpose. Developing the typology of the genre of tourist guides as a tool for adequate, precise publication titulary.

Method. Paging and diagnosing studies revealed the existence of guides without precise titles. To assess the scale of this phenomenon, a collection of 99 pieces of tourist guides from 1989-2009 gathered in a random manner was prepared. Empirical research of this collection was undertaken. Representativeness of the sample was considered sufficient in connection with ensuring territorial, chronological and species-related homogeneity. Statistical methods and techniques were used: statistical average of the occurrence of selected characteristics of the titulary in order to derive qualitative conclusions taken into account during the creation of the typology.

Findings. The concept of multicriterial typology of the genre along with the definition of a tourist guide, as the basis for the new standards of tourist guide titles.

Research and conclusions limitations. The research concerned Polish guides. Defining the guide and typology requires further research of the guide's empirical reception for corrections resulting from new trends in tourism.

Practical implications. Typologies may be used by entities present in the publishing or library classifications. Adequate to the content of the multicriteria, titulary may help authors. The examples of the use of typology in constructing a hypothetical title of the guide are shown.

Originality. A large number of examined guides. It is not without significance that the recipients understand the intentions of the author. So far, no such research topic has been undertaken. No tool was proposed to solve the titulary adequacy in relation to the contents of the guides.

Type of paper. Article discussing the concept of typology supported by empirical research with examples of its application.
Bakterie enteropatogenne w środowisku pracy pracowników oczyszczalni ścieków
Authors: Stobnicka Agata
Published: April 2020

Wody zanieczyszczone ściekami stanowią potencjalne źródło zagrożenia epidemiologicznego, w związku z czym pracownicy oczyszczalni ścieków stanowią grupę zawodową szczególnie narażoną na kontakt z enteropatogenami bakteryjnymi w trakcie wykonywania czynności zawodowych. Źródło wspomnianych czynników biologicznych może stanowić zarówno bioaerozol, emitowany w trakcie procesów technologicznych, jak również kontakt ze ściekami, osadami ściekowymi czy zanieczyszczonymi powierzchniami. Narażenie na enteropatogeny bakteryjne może stać się przyczyną różnych chorób i dolegliwości zdrowotnych, obejmujących zarówno infekcje jelitowe, jak i pozajelitowe. Głównymi elementami prewencji zagrożeń zawodowych w tej grupie pracowników powinna być rzetelna ocena ryzyka oraz stosowanie odpowiednich środków profilaktycznych.

Published: April 2020

W artykule przedstawiono wyniki badań drgań działających w sposób ogólny na 30 stanowiskach pracy związanych z przeróbką surowców mineralnych. Analiza narażenia na drgania ogólne wykazała, że na tego typu stanowiskach pracy mogą wystąpić przekroczenia wartości dopuszczalnych. Na 7 spośród zbadanych stanowisk ryzyko zawodowe ze względu na drgania ogólne oszacowano jako duże. Na 6 stanowiskach pracy wyznaczone wartości dziennych ekspozycji przekraczały 0,5 NDN (ryzyko średnie), także na 6 stanowiskach nie przekraczały 0,5 NDN (ryzyko małe). Na 11 stanowiskach ryzyko zawodowe oszacowano jako pomijalnie małe (wartości dziennych ekspozycji nie przekraczają 0,2 NDN). Uzyskane wyniki badań wskazują na potrzebę przeprowadzania pomiarów kontrolnych i oceny drgań ogólnych na stanowiskach pracy związanych z przeróbką surowców mineralnych.
Free Cross-Border Movement, Lucifer’s Effect and National Security of the Visegrad Countries

Published: April 2020

Since 2015, the migration crisis continues with varying intensity, and international security crisis as well as debt, institutional, and personnel crises are worsening, not only in the Eurozone. Probably war, economic and climate immigrants will continue to move into the Schengen area, showing how helpless the European Union is. Angela Merkel said there was no upper limit for the number of people admitted to escape political persecution. Germany leaves the Dublin system inconsistently, runs counter to European cohesion and stops differentiating between immigrants and refugees. Migration is shared by the EU Member States. Between “old” and “new” EU countries, scissors are opened. Moreover, in some European regions (France, Belgium, Germany, Sweden, the United Kingdom, Spain, Greece) there are closed communities where majority law is not valid. Our current socio-political and economic existence is based on a traditional understanding of security. However, in the third decade of the 21st century the image of prosperity and security is to be seen from a different perspective than in previous years. Dramatic development has led to the mass migration of African and Asian people and to the division of the European Union, especially regarding the mechanism of redistribution of asylum seekers.
Research on the Concrete Mixture Stability and Sliding on the Inclined Plane

Published: April 2020

The stability of conventional concrete mixture was investigated using an inclined plane method. The experiment consisted of two steps: first, the research was made to determine the influence of coarse aggregate content in aggregates mixture on the stability and sliding of concrete mixture, when the specimens of mixture are on the inclined plane without additional roughening of surface; second, the research was made to determine the influence of inclined plane surface roughening on the stability and sliding of concrete mixture. During the research the condition was checked: the concrete mixture on the sloping plane will be stable, if the yield stress τ0 is higher than the shear stress τ in. (τ 0 ≥ τ). The shear stresses and rheological property yield stresses of conventional concrete mixtures were calculated analytically by using an empirical formula. Test results showed that the increase of coarse aggregate (4/16 fraction gravel) content from about 417 to 1175 kg in concrete mixture is enough to achieve the stability of concrete mixture, when plane inclination angles are 25°, 35° and 45°, but not enough to stop sliding process. In this case, additional implements are needed to increase the adhesion of fresh concrete to the base. By using the inclined planes, which were coated with a special dimpled membrane and geotextile, the fresh concrete does not slide downwards by inclined plane.
An Investigation on Post-Disaster Housing Resident Satisfaction in Subaşı After the Marmara Earthquake
Authors: BODUR ALPER
Published: April 2020

Turkey is a nation experiencing disasters, particularly earthquakes, owing to its location. Accidents cause environmental destruction as much as economically. One of the significant bodily damages is that the residences become damaged. Accordingly, the need for housing is indispensable after a collision. To deal with the problem, permanent houses, post-disaster housing, in other words, are produced in numerous regions to afford service for households. Post-disaster housing is essential to helpless families so that all will be capable of returning a fitter living situation ere the disaster.

Nevertheless, as permanent housing is made by building it very fast, it is imperative that the living standard of permanent residence is agreeable with the earlier practice of the users. In that way, post-use evaluations of permanent housing, uniquely constructed after the devastating result of a disaster, are becoming critical to following applications to be more prosperous. In this sense, permanent residences in Subaşı Village, Yalova Province in Turkey have been studied within the context of post-earthquake transformation applications on 17 August 1999. In the research, the planning of the houses built in Subaşı Village, the overall evaluations about the design, the principles of entitlement, the planning method of the permanent houses, the demographic features of the shareholders were evaluated.

As an outcome of the research, it was observed that the permanent residential areas in Subaşı village could not unite with the existing city. Among the socialization processes of families with various features, it was regarded that distinct qualities of contribution were made to living spaces. Neighborhood relationships and concern for free spaces and ownership organizations influence social relations together. Personal solutions to designs and absence of ownership regulation in public areas further block the formation of administrative units in permanent residential zones. Hence, interspersed life in the areas of current housing does not emerge. The situation has led to the result that in the process of combination of permanent residential spaces with existing urban areas, social facilities and non-residential uses, business and shopping centers, mosque and sports halls should be raised within a wider frame.
