Public Amenities in Rural Suburban Settlements in Bratislava’s Hinterland
Authors: Sopirová Alžbeta , Bradová Ivana 
Published: April 2019

Abstract
The present paper examines selected urbanistic parameters of public amenities in rural residential areas in the suburban hinterland of Bratislava, which has undergone a rapid development in the past 20 years. In an overall perception of a residential area in terms of its attractivity and vitality, the location, type, structural and technical condition of buildings have a significant influence, together with related public spaces that are indicative of the place’s continuity of development, identity, specificity and standard of living. A quantitative comparison of public amenities presents the differences between selected municipalities on the Danube development axis and their causal relationships. This paper suggests the minimum standards of public amenities necessary for a positive identification with a residential area on both the locals’ and the visitors’ part.
Investment Strategies that Beat the Market. What Can We Squeeze from the Market?

Published: April 2019

Abstract
The paper presents a new approach to optimizing automatic transactional systems. We propose a multi-stage technique which enables us to find investment strategies beating the market. Additionally, new measures of combined risk and returns are applied in the process of optimization. Moreover, we define new elements of a risk control system based on volatility measures and consecutive signal confirmation. As a result, we formulate three complex investment systems which maximize returns and simultaneously minimize risk in comparison to all other alternative investments (IR=2, Maximum Drawdown<21%, Maximum Loss Duration=0.75 year). Our analysis is based on historical daily data (1998-2010, in- and out-of-sample period) for index and commodity futures. Afterwards, the systems are reoptimized and reallocated each half a year in order to include the most recent financial data. Finally, we show the results for a joint model consisting of our three systems.

Abstract

Introduction: Canine transmissible venereal tumour (CTVT) is a sexually transmitted tumour affecting dogs worldwide, imposing a financial burden on dog owners. A stable culture cell line in continuous passages for >18 months has only been achieved once. The present study investigated a stable CTVT cell line isolated from a bitch and its potential as a vaccine. Material and Methods: A biopsy from a 2-year-old mongrel bitch with CTVT was obtained for histopathological confirmation and isolation of tumour cells. The isolated cells were cultured to passage 55 and characterised by flow cytometry, with karyotyping by GTG-banding and by PCR detection of myc S-2 and LINE AS1. The isolated CTVT cell line was also used as a preventive vaccine in a canine model. Results: Histopathological analysis of the isolated tumour cells revealed typical CTVT characteristics. Constant proliferation and stable morphological characteristics were observed during culture. Phenotypic analysis determined the expression of HLA-DR+, CD5.1+, CD14+, CD45+, CD83+, CD163+, and Ly-6G-Ly-6C+. GTG-banding revealed a mean of 57 chromosomes in the karyotype with several complex chromosomal rearrangements. LINE-c-myc insertion in the isolated CTVT cell line at 550 bp was not detected. However, a 340-bp band was amplified. Isolated CTVT cell line inoculation at a concentration of 1×108 did not induce tumour growth in bitches, nor did a challenge with primary CTVT cells. Conclusion: The present study successfully identified and isolated a stable CTVT cell line that may be useful in CTVT prevention.
The delimitation of planning regions on the basis of functional regions: An algorithm and its implementation in Turkey
Authors: Beyhan Burak 
Published: April 2019

Abstract
The proper delimitation of planning regions is a critical issue in the success of regional plans, and it constitutes a rich domain of research. In this paper, it is argued that planning regions should be based on functional regions– if the main intention is to increase the driving power of the people behind the planning process. Within this context, the aims of this paper are twofold: (1) to develop an algorithm (FRGIS) for the delimitation of planning regions on the bases of functional regions, and to implement it by using the scripting facilities available in Free and Open Source Software for Geographic Information Systems (GIS); and (2) to delimit the planning regions in Turkey by using FRGIS and the script developed for this purpose, by employing the commuting flows occurring between districts in the case country (Turkey) in 2010. The results show that FRGIS is successful in terms of the formation of spatially-balanced regions having higher levels of self-containment compared to those of existing regions. Nevertheless, it is also evident from this study that a combination of the nomothetic and ideographic methods of science is inevitable if functional regions are to be employed as planning regions.
The Application of Phenomenological Methodology for Designing Pile Foundation in Port Structures
Authors: Więcławski Paweł 
Published: April 2019

Abstract
It is of utmost importance in the design process that a suitable, safe and concurrently economic solution be chosen. Issues connected with foundations require adopting a special approach. Soil is a composite medium, and it is essential to describe as precisely as possible the interaction taking place between the subgrade and the structure. There are many design methods of pile foundation that are based on in-situ test of soils. As a result of incessant development of the pile installation technology, the results obtained with design methods used to date do not assure the required accuracy, and consequently the values of pile load capacity are not sufficiently accurate. A partial solution to this problem may be applying the observation method. Based on assumptions of phenomenology as a science that enable cognition of natural and mathematical phenomena, a procedure has been developed for projecting loading-settlement dependencies for Vibro piles installed in port areas in Poland. Those areas are characterised by similar soil and water conditions, as well as soil genesis and parameters. This procedure enables estimating the limit of load capacity values with much better accuracy than the hitherto used direct methods. The full range of the s(Q) function also enables the possibility of designing structures allowing for stringent criteria of admissible settlements having a specified value.

Published: April 2019

Abstract
In the paper, the measurement and simulation results of the VDES (VHF Data Exchange System) terrestrial component are discussed. It is anticipated that VDES will be one of the major solutions for maritime communications in the VHF band and its performance will be sufficient to fulfill the requirements of the e-navigation applications. The process of the VDES standardization (ITU R, IALA) has not been officially completed yet, but substantial amount of technical information about the future system’s terrestrial component (VDE-TER) is already available. The paper is divided into three general parts: (a) theoretical presentation of the system’s physical layer and the radio channels applicable to VDES, (b) simulation results (BER, BLER, channel delay between two propagation paths and its influence on bit rates) and (c) measurement results (useful ranges, BER). It turned out that in real maritime conditions, the VDES system can offer ranges between 25 and 38 km for the configurations assumed during the measurement campaign. Those results are generally compliant with the theoretical data in the line-of-sight conditions. In the NLOS scenarios, where fading becomes the dominant phenomenon, the discrepancies between the measurements and the theoretical results were more significant. The obtained results confirmed that VDES provides a large coding gain, which significantly improves the performance of data transmission and increases the bit rate compared to the existing maritime radiocommunication solutions. It should be noted that the results presented in the article were used by the IALA while developing the current version of the VDES specification.
Consensus for Multiple Unmanned Surface Vehicle (Musv) Systems with Markov Switching Topologies
Authors: Wang Liyuan , Yue Wei , Zhang Rubo 
Published: April 2019

Abstract
This paper is concerned with sampled-data leader following consensus of multiple unmanned surface vehicle (MUSV) systems with random switching network topologies and wave-induced disturbance. By modelling the switching of network topologies with the use of a Markov process and considering the effect of wave-induced disturbance, a new sampled-data consensus control protocol is proposed. By employing an appropriate Lyapunov-Krosovskii function method and the weak infinitesimal operation, a novel stability criterion is derived, which ensures that the MUSV system can reach robustly leader-following consensus with H∞ performance satisfied. Based on this criterion, the Markov dependent switching consensus controller gains are obtained by solving a set of linear matrix inequalities. Finally, an illustrative example is given to verify the effectiveness of the proposed control scheme for MUSV systems.
Hydraulic Analysis of Causes of Washout of Gdynia-Orłowo Sea-Shore During the Flood in the Kacza River Estuary
Authors: Szydłowski Michał 
Published: April 2019

Abstract
In July 2016 in the Three-city agglomeration a rainfall episode of over a day duration and 150 mm summary rainfall height, occurred. This situation, extreme as for Polish conditions, caused significant freshets in rivers and streams running into Gdansk Bay, the Baltic Sea, and serving as collectors of rainfall waters for the sea-coast towns. In many areas of the Three-city flood phenomena and overflows took place. The flood also occurred in the catchment area of the Kacza river in Gdynia. The passing of flood water rise caused damage of many infrastructure objects located along the river valley. The estuary section of the river suffered most, especially sea-shore belt together with beach around the estuary which were significantly washed out. In this paper an approach was made to answer to the question on direct causes of the situation which occurred at the estuary of the Kacza river. To this end, there was worked out a hydrodynamic model of the considered section of the river, based on the solving of two-dimensional differential motion equations of free-surface liquid, and simulations of water flow propagation along the river’s valley were performed for a few variants of hydraulic engineering infrastructure of river bed. Numerical hydraulic analysis made it possible to determine a role of the hydraulic engineering objects in forming the flood water rise as well as their impact on location and range of washout zones of sea-shore belt.
Individual Capacities of Hellwig’s Information Carriers and the Impact of Attributes in the Szczecin Algorithm of Real Estate Mass Appraisal
Authors: Doszyń Mariusz 
Published: April 2019

Abstract
A statistical method of defining the impact of real estate attributes based on individual capacities of Hellwig’s information carriers was proposed in the paper. The method may be used for defining the impact of attributes in the Szczecin algorithm of real estate mass appraisal. The proposed procedure refers to the so-called Hellwig’s method, used for the selection of explanatory variables in an econometric model. In the case of real estate attributes, we typically deal with variables measured on an ordinal scale. Therefore, Kendall’s tau coefficients (tau a, tau b, tau c) will be applied in order to determine the strength and direction of a relation between variables. These coefficients enable the measuring of the strength and direction of a relation between variables measured on an ordinal scale. After valuating proper matrices of Kendall’s tau coefficients, individual capacities of Hellwig’s information carriers were determined, on the basis of which the impact of attributes in the Szczecin algorithm of real estate mass appraisal was defined. The proposed procedure was supported with an empirical example using a real data base that comprises 99 undeveloped land properties of industrial designation, including depots, storehouses, warehouses, and yards. After determining the impact of each attribute, the Szczecin mass appraisal algorithm was used to evaluate values. The obtained real estate values were very close to the values obtained by real estate experts.

Authors: Serocka Izabela 
Published: April 2019

Abstract
Conditions underlying the undertaking and developing of a business enterprise in a specific location are strictly connected to the state and any possible modifications of the spatial management in a given area, and the local government of every municipality is obliged to ensure spatial order and to manage the land resources so as to take into account their economic assets.
The main purpose of this study was to identify the role of a variety of relevant factors as well as the activities performed by local governments in eastern Poland that arise from with the local policy of a municipality, the smallest unit in Poland’s administrative division, in connection with the location of business enterprises.
The research enabled us to determine what activities in the domain of spatial policy are implemented by local governments and what role they play in the enhancement of economic values of a municipality. The results also helped to indicate which spatial policy factors lose and which gain importance in the context of conducting a business activity. The most important factor in terms of the location a business investment in a given area is the active implementation of the municipality’s spatial policy. The factor that gains the highest importance in the eyes of entrepreneurs is the condition of technical infrastructure.

Bullying in a form of intimidation that junior peers receive from their seniors are still happening in several high schools in Jakarta area, namely XYZ High School. The immediate effect of intimidation include fear of being near any place in that specific school that is considered as the senior turf. This in turn affects negatively on the students' sense of security and feeling of peace, thus possesses threats on their academic as well as non-academic achievements. This research aims to empower students to become bystanders who are willing to intervene thus prevent the occurrence of bullying. The students' willingness to be able to intervene requires certain skills in empathy, thus this intervention program provides training to increase empathy aimed at a group of student council members in order for them to be able to intervene properly. Literatures in empathetical skills used in the design of this program will increase prosocial behaviour so that bullying will decrease on its own after its delivery. The program includes: recognizing others' perspectives, recognizing others' needs, and increasing the sense within self to help others in need. This research used an action research design that focuses on explorative narratives. Analysis used a Wilcoxon signed-ranks that showed students' empathetical skills increased after intervention of program was delivered (pretest-post test score on empathetical skills IRI Z = 2,836, p <0,005). The increased empathetical skills in students are expected to decrease bullying behaviour within XYZ High School in Jakarta.

Published: April 2019

Pembelajaran tematik merupakan pembelajaran yang menggunakan tema untuk memadukan beberapa mata pelajaran atau bahan ajar, agar pembelajaran lebih bermakna bagi siswa. Meskipun pembelajaran tematik sudah diterapkan sejak Kurikulum Berbasis Kompetensi (2004) namun sampai saat ini (2017/2018) masih ada kepala sekolah dan guru SD yang mengalami kendala dalam mengimplemen-tasikan pembelajaran tematik. Penelitian ini merupakan penelitian deskriptif kualitatif yang bersifat kolaboratif dengan membandingkan implementasi (persiapan, pelaksanaan, dan penilaian) pembelajaran tematik di lima SD swasta di DKI Jakarta yaitu SD Santa Maria (JakPus), SD Strada Santo Ignatius (JakUt), SD Tarakanita 5 (JakTim), SD Kartika X-2 (JakSel), dan SD Bintang Kejora (JakBar). Perencanaan dalam bentuk Prota, Promes, dan Silabus sudah mengikuti panduan, hanya perlu disesuaikan dengan kalender sekolah, sedangkan penyusunan RPP dan perangkatnya dibuat guru pararel seminggu sekali. Pelaksanaan di kelas 1 sudah menerapkan tematik terpadu, sedangkan di kelas 4 masih tematik terjaring, menggunakan model dan metode pembelajaran cukup bervariasi dan mengaktifkan siswa, dan melaksanakan langkah pembelajaran saintifik walaupun belum optimal. Penilaian dalam bentuk penilaian autentik masih dirasakan sulit sehingga perlu dicari cara yang lebih memudahkan guru dalam mempersiapkan dan melakukan penilaian.
