Wybrane zagadnienia dotyczące budowy tuneli z wykorzystaniem zmechanizowanych tarcz zawiesinowych
Authors: Michalczuk K. , Lipinski M. , Wdowska M.
Published: October 2019

Głównym kryterium determinującym wybór technologii tunelowania z wykorzystaniem tarczy zmechanizowanej, tzw. TBM (ang. tunnel boring machine), są warunki geologiczne i hydrogeologiczne w obszarze planowanej inwestycji. W przypadku gruntów nieskalistych można je podzielić na dwie kategorie: spoiste i niespoiste. Określenie parametrów geotechnicznych istotnych przy tunelowaniu wymaga indywidualnego podejścia. Jednym z podstawowych kryteriów określenia parametrów gruntu jest właściwy dobór metody ich wyznaczania. W przypadku prowadzania robót tunelowych z wykorzystaniem tarcz zawiesinowych TBM i wykonywania obliczeń związanych ze statecznością przodka wyznaczanie i analiza parametrów geotechnicznych powinna odnosić się do warunków bez odpływu. W artykule przedstawiono zasady schematyzacji warstw geotechnicznych w pakiety o zbliżonych parametrach wytrzymałościowych. Prawidłowa schematyzacja jest ważna, gdyż interpretacje profili geologiczno-inżynierskich, które zawierają zbyt dużo wydzielonych warstw geotechnicznych o podobnych własnościach, w zasadzie uniemożliwiają wykorzystanie ich w obliczeniach i analizach MES. Należy również zwrócić uwagę, że nadmiernie drobiazgowy i niecelowy podział na warstwy geotechniczne nie wynika z żadnych zapisów aktów prawnych, norm oraz instrukcji, ale jest efektem często spotykanej nieprawidłowej praktyki. W artykule przedstawiono przykłady prawidłowych rozwiązań oraz zasad w zakresie podziału podłoża na jednorodne warstwy w odniesieniu do budowy tuneli z wykorzystaniem zawiesinowych tarcz zmechanizowanych.

Authors: Tahan Mohammad , Kalantari Masume
Published: October 2019

Considering the physical, psychological and social preparation of the child in pre-primary school for advancement in various aspects of development and the certificate of various researches, the positive effect of this course's education on the social adjustment of primary school children requires more attention to pre-school education. The elementary school is useful and necessary in terms of quantitative and qualitative and conducting appropriate studies to evaluate the effects and improve the content and conduct of the training. The purpose of this study was to investigate the effectiveness of preschool education on social adjustment of primary school students.The method of this research is post-event (causal-comparative), in which a 320-person elementary school students (160 of whom had pre-primary education and 160 without pre-school education) had adaptive behavior questionnaires. Randomized sampling was performed and the results were analyzed. . Findings of this study showed that there is  no significant effect on pre-school education on social adjustment of elementary students. The results of this study confirm the view that children can not be sent to preschool centers in the hope that they will only have the effect of preschool experience on the development of their social adjustment, but also the quality of the programs of these centers, the personality and the way of communication. The teacher is the center of space and the amount of pre-school experience that matters in this area.Keywords: preschool education, social adjustment.
Kuvajournalismi ja eettisen kuluttamisen haaste
Authors: Niemelä-Nyrhinen Jenni , Seppänen Janne
Published: October 2019

Artikkelissa tarkastelemme Aamulehdessä julkaistuja eettistä kuluttamista representoivia kuvajournalistisia valokuvia. Keskeinen kysymyksemme on: Millaista eettisen kuluttamisen todellisuutta kuvajournalistiset valokuvat rakentavat? Pohdimme myös, millainen kuvajournalismi voisi edesauttaa ihmisten sitoutumista ympäristön kannalta kestävään arkeen. Tutkimuksessa hyödynnämme muun muassa aiempaa kuluttajakäyttäytymisen tutkimusta, jonka pohjalta rakennamme moniulotteisen kuvan eettisestä kuluttamisesta. Analysoimme aineistoa määrälliseen sisällönanalyysiin nojautuvan kehysanalyysin keinoin. Eettinen kuluttaminen on Aamulehdessä kehystetty kapeaksi ilmiöksi, jossa yksittäisen kuluttajan vaikutusmahdollisuudet painottuvat lähinnä ruokaan liittyviin valintoihin. Kuvia hallitsevat iloiset kuluttajat ja ruokaan liittyvät ammattihenkilöt. Lisäksi kuvissa on ruokaa, ruokapakkauksia ja teknologiaa. Kuvien ihmiset esittelevät ratkaisuja tai poseeraavat. Toimintaa on siis rajallisesti ja yhteys ihmisten arkeen ja kokemuksiin jää pinnalliseksi. Lisäksi ratkaisujen ja ongelmien välinen kytkös on usein jutuissa niin kuvallisesti kuin sanallisestikin löyhä, jolloin on lukijan vastuulla hahmottaa, mihin ongelmaan jutussa esiteltyä eettisen kuluttamisen ratkaisua tarjotaan. Aikaisemman tutkimuskirjallisuuden valossa tarkasteltuna Aamulehden kuvasto ei herättele lukijoita eettiseen kuluttajuuteen.

Data envelopment analysis models for the assessment of efficiency of sustainable forest management in Poland
Authors: Masternak-Janus Aneta , Masternak Katarzyna
Published: October 2019

The aim of the presented research was to analyse the efficiency of forest management as an approach to promote sustainable multifunctional forestry. A total of 17 Regional Directorates of State Forests (RDSFs) in Poland were studied with the use of data envelopment analysis (DEA). This method has been proposed and tested using criteria and indicators (C&Is) as inputs and outputs of the created models. The research process was divided into two stages: first, we analysed the efficiency of simple DEA models and models with additional variables, which allowed us to determine the major models providing the best combination of efficiency evaluation criteria. Second, we used these models to assess the efficiency of sustainable management of forests by RDSFs. According to our results, RDSFs were found to be highly efficient in converting resources into production and nonmarket results. Nevertheless, the implementation of sustainable development principles requires further actions, in order to fulfil all ecological, economic, and social functions in a more effective way. They are connected with the necessity to increase the areas of both protective forests and promotional forest complexes. Thus, the results of this study might be a valuable source of information for the planning process of forestry services at the strategic and operational levels.
How can we attract and keep young talents in the science sector? Work satisfaction and the inclination to change your workplace
Authors: Feldy Marzena
Published: October 2019

Gradually dropping number of working age people, dropping rate of unemployment and continuously growing number of job vacancies, which remain open for a longer time, lead to a situation in which more and more often in the context of Poland people say the market belongs to the employee. What doesn’t alleviate the situation is the arrival of a new generation, the so-called millennials, on the market. Millennials differ from earlier generations both in terms of their characteristics and expectations with regard to their workplace.

The fact that over a half of scientists below the age of 35 employed in national scientific institutions consider changing their work, makes it necessary to focus more on employees’ needs. The goal of this article is highlighting the aspects of work which make it possible to young scientists to achieve satisfaction from professional sphere of life and thus could prevent their outflow from the sector of science.

In 2017 OPI PIB carried out a survey on a representative sample of scientific employees, which included 264 respondents born after 1981. The collected empirical materials allowed the author to analyze the expectations of young people from the sector of science with regard to their workplace. The assessments of scientists who consider changing their employer with the assessments of people who don’t have such plans have been compared.

The conducted survey leads to the conclusion that young people should above all be given the opportunity to develop and work towards achieving their own scientific aspirations. It is also necessary to guarantee the feeling of stability of employment and satisfactory remuneration. What also turns out to be significant is the organization of space, as well as providing flexible work conditions and recognition from the superiors.

Satisfying at least some of the highlighted proposals won’t be possible without introducing systemic changes. Failure to intervene in such a way will lead to a situation in which the national sector of science will in the nearest years be gradually losing valuable employees, which will be migrating to the company sector and foreign scientific institutions.
On the Minimal Adequate Sampling Frequency of the Photoplethysmogram for Pulse Rate Monitoring and Heart Rate Variability Analysis in Mobile and Wearable Technology
Authors: Béres Szabolcs , Holczer Lőrinc , Hejjel László
Published: October 2019

Recently there has been great interest in photoplethysmogram signal processing. However, its minimally necessary sampling frequency for accurate heart rate variability parameters is ambiguous. In the present paper frequency-modulated 1.067 Hz cosine wave modelled the variable PPG in silico. The five-minute-long, 1 ms resolution master-signals were decimated (D) at 2-500 ms, then cubic spline interpolated (I) back to 1 ms resolution. The mean pulse rate, standard deviation, root mean square of successive pulse rate differences (RMSSD), and spectral components were computed by Varian 2.3 and compared to the master-series via relative accuracy error. Also Poincaré-plot morphology was assessed. Mean pulse rate is accurate down to 303 ms (D) and 400 ms (I). In low-variability series standard deviation required at least 5 ms (D) and 100 ms (I). RMSSD needed 10 ms (D), and 303 ms (I) in normal, whereas 2 ms (D) and 100 ms (I) in low- variability series. In the frequency domain 5 ms (D) and 100 ms (I) are required. 2 ms (D) and 100 ms (I) preserved the Poincaré-plot morphology. The minimal sampling frequency of PPG for accurate HRV analysis is higher than expected from the signal bandwidth and sampling theorem. Interpolation improves accuracy. The ratio of sampling error and expected variability should be considered besides the inherent sensitivity of the given parameter, the interpolation technique, and the pulse rate detection method.
Student Discussion from an Evolutionary Perspective
Authors: Metzgar Matthew
Published: October 2019

Student discussion has been identified as a key ingredient in overall student learning (Flynn & Klein 2001; Safari et al 2006). However, in many classrooms, there is little to no discussion between teachers and students or among students themselves. This may result from high student-teacher ratios, or from the chosen pedagogy of the instructor.A variety of ideas to increase class discussion have been proposed over time. A number of these ideas have been shown to increase student learning (Freeman et al 2014 for a recent meta-analysis). This paper attempts to analyze student discussion from a human evolutionary standpoint. Such a view may add new insights into how discussion can be effectively used in the classroom.While looking at discussion from such an evolutionary view, several key questions arise: how and why did humans utilize discussion in the past? What are “natural conditions” for human discussion? How can these ideas help increase the use and effectiveness of discussion within an educational framework? This paper hopes to answer these questions and expound upon the evolutionary origins of productive discussion.

Strategies for Nurses in Antiretroviral Clinics to Mitigate Symptoms of Compassion Fatigue
Authors: Tellie Mercia Jane , Leech Ronell , Van Wyk Neltjie
Published: October 2019

Compassion fatigue has a negative impact on the well-being of healthcare professionals. Compassion fatigue affects nurses physically, emotionally and psychologically, as well as their behaviour towards others. Factors that increase nurses’ risk to develop compassion fatigue include an overwhelming workload, being a secondary witness to their patients’ traumatic experiences, emotional involvement with patients, especially children, lack of managerial support, and dealing with the deaths of their patients. The purpose of this paper is to describe strategies that nurses who work in antiretroviral (ARV) clinics use to mitigate the symptoms of compassion fatigue. A qualitative single embedded case study, utilising semi-structured interviews to collect data in ARV clinics in a tertiary hospital in the Gauteng province of South Africa was used. The process of content analysis as described by Elo and Kyngäs was utilised to analyse the data. The knowledge gained from the research findings contributed towards the identification of strategies that nurses use to prevent and manage compassion fatigue ? strategies such as debriefing, management support, psychological support, self-care, collegial support, and celebrating patients’ lives. If compassion fatigue is not recognised early and managed properly, it will have a negative impact on the quality of care and can result in an increase in the turnover rate of staff ? therefore the need for strategies that will mitigate the symptoms of compassion fatigue.

Authors: Khoiriyah Khoiriyah , Ardiananto Hendi
Published: October 2019

Head injury is one of the main causes of death and disability in the productive age group and most occur due to traffic accidents. Patients with a head injury can experience permanent damage to brain tissue or secondary injuries such as brain ischemia due to hypoxia, hypercapnia, hyperglycemia or electrolyte imbalance, even respiratory failure and heart failure. The head injury patients are initially examined using a standardized scoring system to assess the consciousness level of patients with impaired consciousness, namely the Glasgow coma scale (GCS). One of the possible treatments for decreasing intracranial pressure (ICP) and cerebral perfusion managements to position the patients with a head elevation of 15˚-30˚. This treatment aimed  to increase venous drainage from the head and to reduce systemic blood pressure that may be compromised by cerebral perfusion pressure. This study aimed to determine the effect of giving oxygen through a simple mask and the 30˚ head elevation position to the changes of the consciousness level for the patients witha head injury in the emergency department at Dr. Kariadi Hospital, Semarang. This study was quasi-experimental research without control with pre-test and post-test one-group design with used a sample of 23 respondents. The instrument used an observation sheet containing the GCS examination results and analyzed using the Wilcoxon test. Based on the results of the bivariate analysis using the Wilcoxon correlation test, a p-value of 0,000 <0,05 was obtained so it could be concluded that the H0 is accepted. Therefore, giving oxygen through simple masks and patient positioning with 30˚ head elevation affect the consciousness level of head injury patients at Dr. Kariadi Hospital, Semarang.

MIXED TRIPLE TWO-POINT CORRELATIONS OF VELOCITY AND VELOCITY GRADIENTS IN HOMOGENEOUS ISOTROPIC TURBULENCE
Authors: Kopyev A.V. , Zybin K.P.
Published: October 2019

On the basis of Kolmogorov’s 4/5 law (Kolmogorov, 1941; Landau, Lifschitz 1975) analytical relations for triple two-point correlations of velocity and velocity gradients in homogeneous isotropic incompressible turbulence are derived (Kopyev, Zybin, 2018). The corresponding correlation tensor can be expressed in terms of the dissipation rate, the second-order correlation function for the longitudinal velocity increment, and the new scalar function of distance between the points. However, some components of the tensor do not depend on the new function. The derived analytical results are in agreement with the data obtained from direct numerical simulations. The function can be well approximated in the inertial range by a constant value that depends on the dissipation only. The application of the obtained correlators in the turbulent transport theory is discussed (Il’yn, Sirota, Zybin, 2016; Kazantsev, 1968).
The study was performed in Central Aerohydrodynamic Institute (TsAGI) with the funding of Russian Science Foundation (project No. 17-11-01271).
COMPACT FINITE-DIFFERENCE SCHEMES FOR WEAKLY NON-LINEAR PROBLEMS AND BOUNDARY CONDITIONS IMITATING CAUCHY PROBLEM
Authors: Gordin V.A.
Published: October 2019

Compact finite-difference schemes are well known and provide high accuracy order for differential equation with constant coefficients.
Algorithms for constructing compact schemes of the 4-th order for boundary value problems with variable (smooth or jump) coefficient are developed. For the diffusion equations with a smooth variable coefficient and the Levin – Leontovich equation, compact finite-difference schemes are also constructed and their 4-th order is experimentally confirmed. The method of constructing compact schemes of the 4-th order can be generalized to partial differential equations and systems with weak nonlinearity, for example, for the Fisher – Kolmogorov – Petrovsky – Piskunov equation, for the nonlinear Schrödinger equation or for the Fitzhugh – Nagumo system. For such nonlinear problems, a combination of simple explicit schemes and relaxation is used. Richardson’s extrapolation increases the order of the circuits to the 6-th.
To approximate multidimensional problems with discontinuous coefficients, for example, the two-dimensional stationary diffusion equation in inhomogeneous media, it is necessary to estimate the possible asymptotics of solutions in the vicinity of the boundary line’s breaks. To do this, we use generalized eigen-functions in the angle, which can be used as a set of test functions and build compact difference schemes approximating the problem on triangular grids with high order of accuracy. The asymptotics along the radius of these generalized eigen-functions (in polar coordinates in the vicinity of the vertex of the angle) have irrational indices which can be found from a special dispersion equation and which determine the indices of the corresponding Bessel functions along the radius.
For a number of difference schemes approximating the most important evolutionary equations of mathematical physics, it is possible to construct special boundary conditions imitating the Cauchy problem (ICP) on the whole space. These conditions depend not only on the original equation, but also on the type of the difference scheme, and even on the coefficients of the corresponding differential equation. The ICP conditions are determined with accuracy to a gauge. But the choice of this gauge turns out to be essential with numerical implementation. The role of rational approximations of the Pade – Hermite type of the symbol of the corresponding pseudo-differential operator is important. Examples of movie solutions of problems with ICP conditions for various finite-difference schemes approximating the basic mathematical physics equations, see https://cs.hse.ru/mmsg/transbounds.
The study was realized within the framework of the Academic Fund Program at the National Research University – Higher School of Economics (HSE) in 2016–2017 (grant No. 16-05-0069) and by the Russian Academic Excellence Project «5–100».

Blkr) is a potential fish species for aquaculture in Indonesia. However, the growth and survival rate performance can be improved by developing cultivation containers. The research objective was to determine the optimal type of cultivation container to produce high growth and survival rate. The ponds treatments used in this experiment were soil pond, hapa pond and tarpaulin pond with measuring 3 m x 2 m x 1 m. The initial fish length average was 15±1.39 cm, with the initial body weight average of 250.04±1.70 g with the stocking density of 25 individual/pond. During 120 days of the rearing period, the fish were fed with trash fish with a proportion of 30% of body weight with the frequency of feeding 2x a day. The results showed differences in the type of container significantly affected weight gain and specific growth rates but did not significantly affect survival rate. The best weight gain was found in the treatment of soil pond containers at 53.86 ± 1.10 g with a specific growth rate of 0.45 ± 0.010% body weight/day and survival rate of 85.33 ± 6.11%. Water quality in all containers still supports growth and survival rate. The results of this study can be used as necessary information in the selection of effective and efficient aquaculture containers to produce optimal sand goby culture.Keywords: sand goby; growth; survival rate; container

This study aims to determine purchasing decisions among young people who need their daily life is still filled by the lord yes. Android smartphones among young people are still included in the category of expensive items. The sample used is young people who are still learning and have no income. Consumers in determining the decision to purchase products are influenced by including price perceptions, product features, and word of mouth. Consumer complaints about price perceptions are caused by Android smartphones perceived to be more expensive. Price perception is related to how price information is understood entirely by consumers and gives a deep meaning to them, three indicators namely: Price conformity to product quality, Price conformity to benefits and Competitive prices. Product features are elements of a product that are considered important by consumers and are used as the basis for making a purchasing decision, researchers use four indicators, namely: Diversity of Features, Quality of Features, Importance of Features and Completeness of Features. Word of Mouth or WOM is the act of providing any information related to the product by consumers to other consumers. there are three indicators of Word of Mouth, namely: Word of Mouth Organic, Word of Mouth Amplified and Word of Mouth Marketing. The purchase decision is a decision as the choice of an action of two or more alternative choices, there are six indicators namely: Product choice, Brand choice, Time choice, Store choice, Choice of amount and Choice of payment. From the results of this study it was found that the influence of Price Perception (X₁), Product Features (X₂) and Word of Mouth (X₃) on Purchasing Decisions (Y) had a very strong and positive effect because when young people whose financial needs were still met from his parents or young people who have not worked is largely determined by the variable Price Perception (X ₁), Product Features (X ₂) and Word of Mouth (X ₃) together or simultaneously affect the Purchase Decision (Y) of an android smartphone.

Fahmil Qur'an is one of the branches of the Musabaqah Tilawatil Qur'an (MTQ) race. In the Fahmil Quran race, the participants will be given a package of questions - questions that will be tested by the participants' ability to work together when answering questions given by the jury. And the package of questions that are available is printed poorly, allowing the jury to misrepresent the participants. To avoid repetition in giving questions to participants, a system will be built that is able to randomize the questions automatically. Randomizing the question uses a linear congruent method algorithm. In this research there is a system flowchart and manual calculation of the linear congruent method algorithm.
