“As a Native Person,Why Should I Adapt?”:
Authors: Nortio Emma , Renvik Tuuli Anna , Jasinskaja-Lahti Inga 
Published: January 2020

Abstract
Multiculturalism is a controversial concept and a debated topic. To develop scientific analysis and inform political discussions, it is important to study how lay people evaluate it. Previous research has mostly regarded attitudes towards multiculturalism as unidimensional. This research often relies on the operationalisation offered by the Multicultural Ideology Scale (MIS), in which minorities’ cultural maintenance and acceptance of cultural diversity are central. In this multimethod study, we take a critical perspective on such operationalisation and examine majority of Finns’ responses to MIS in a survey and in focus group discussions. By approaching evaluation processes as social interaction, we challenge the unidimensionality assumption of attitudes towards multiculturalism. We show how cultural essentialism and nationalism are used in arguing for and against multiculturalism, and in negotiating its boundaries so that the majority can keep its dominant position. This conflicts with recognition and equality that are widely considered as cornerstones of multiculturalism.

Published: January 2020

Abstract

Introduction. Allergic diseases belong to the most important health problems responsible for the incidence of various types of discomfort. The application of specific allergen therapy (SAI) is becoming a more and more frequent method aimed at treating allergic diseases. However, this approach requires a strict adherence to medical treatment, which may affect patients’ quality of life.

Aim. Assessment of quality of life and everyday functioning in the group of patients who underwent a specific allergen therapy.

Material and methods. The study group consisted of 80 adult patients who decided to undergo SAI treatment and were treated in two health care facilities in Małopolska region. The study included an assessment of life quality and selected aspects of functioning (as well as their retrospective assessment). As far as the applied methods are concerned, the study was based on the authors’ own questionnaire and an abbreviated version of the World Organization Quality of Life-BREF questionnaire.

Results. SAI treatment made it possible to reduce both the incidence (Me=4.00 to 2.00; p<0.001) and intensity (Me=4.00 to 2.00; p<0.001) of allergic symptoms. Also the discomfort caused by the allergy was decreased (Me=4.00 to 2.00; p<0.001). Moreover, some improvement in general well-being (Me=4.00 to 5.00; p<0.001) and life satisfaction (Me=4.00 to 5.00; p<0.001) was observed.

Conclusions. Specific allergen immunotherapy seems to be worth considering as it improves patients’ life satisfaction and reduces discomfort caused by the allergy itself.

Mean-Square Non-Local Stability of Ship in Storm Conditions of Operation
Authors: Nekrasov Valeriy 
Published: January 2020

Abstract
The purpose of the paper is to create a method for studying nonlocal stability in the mean and in the mean square of the ship, positioned on the beam of an intensive wind–waves mode, which is based on the use of the correlation theory of random functions close to continuous Markov processes. With the help of this method and the integral formula of event probability, a method for determining the reliability indicator of the ship in respect of the existing wind–waves excitations of the operating area is formed. An example of investigating the nonlinear motion of the ship, determining its local and nonlocal stability in the first approximation of the theory of considered random functions, is given. Such approximation uses correlation theory with models of acting excitations represented by the generalised derivatives of the Wiener process. Moreover, special attention is paid to reflecting the connection of the proposed methods for investigating the ship stability under constantly acting random excitations with the traditional methods of studying ship stability at small and large inclinations. The established connection defines the proposed methods as a development of the traditional methods of ship stability deterministic theory during the transition to its formation in the class of random functions, with the addition to these methods of the missing link of determining the level of reliability of ships towards the acting wind–waves excitations of the operation area.
Manoeuvring Prediction of KVLCC2 with Hydrodynamic Derivatives Generated by a Virtual Captive Model Test
Authors: Dai Kun , Li Yunbo 
Published: January 2020

Abstract
This paper describes the application of computational fluid dynamics rather than a towing tank test for the prediction of hydrodynamic derivatives using a RANS-based solver. Virtual captive model tests are conducted, including an oblique towing test and circular motion test for a bare model scale KVLCC2 hull, to obtain linear and nonlinear hydrodynamic derivatives in the 3rd-order MMG model. A static drift test is used in a convergence study to verify the numerical accuracy. The computed hydrodynamic forces and derivatives are compared with the available captive model test data, showing good agreement overall. Simulations of standard turning and zigzag manoeuvres are carried out with the computed hydrodynamic derivatives and are compared with available experimental data. The results show an acceptable level of prediction accuracy, indicating that the proposed method is capable of predicting manoeuvring motions.
A Practical Approach to the Assessment of Waterjet Propulsion Performance: The Case of a Waterjet-Propelled Trimaran
Authors: Zhang Lei , Zhang Jia-ning , Shang Yu-chen , Dong Guo-xiang , Chen Wei-min 
Published: January 2020

Abstract
To obtain a reasonable evaluation of the performance of waterjet propulsion at the design stage, a semi-theoretical and semi-empirical method is used to calculate the fundamental parameters of waterjet propulsion performance using an iterative approach. To calculate the ship’s resistance, a boundary element method based on three-dimensional potential flow theory is used to solve the wave-making resistance, and an empirical approach is used to evaluate the viscous resistance. Finally, the velocity and pressure of the capture area of the waterjet propulsion control volume are solved based on turbulent boundary layer theory. The iteration equation is established based on the waterjet-hull force-balance equation, and the change in the ship’s attitude and the local loss of the intake duct are considered. The performance parameters of waterjet propulsion, such as resistance, waterjet thrust, thrust deduction, and the physical quantity of the control volume, are solved by iteration. In addition, a PID-controlled free-running ship model is simulated using the RANS CFD method as a comparison. We apply the proposed approach and the RANS CFD method to a waterjet-propelled trimaran model, and the simulation process and the results are presented and discussed. Although there are some differences between the two methods in terms of the local pressure distribution and thrust deduction, the relative error in the evaluation results for the waterjet propulsion performance is generally reasonable and acceptable. This indicates that the present method can be used at the early stages of ship design without partial information about the waterjet propulsion system, and especially in the absence of a physical model of the pump.
A Method to Determine the Tightening Sequence for Standing Rigging of a Mast
Authors: Samson Leszek , Kahsin Maciej 
Published: January 2020

Abstract
The article proposes an alternative method to determine the sequence of generation of pre-tension forces in standing rigging of a mast. The proposed approach has been verified on both a virtual simulation experiment and laboratory tests. In this method, the desired tension values are obtained using the influence matrix which allows to calculate the effect of tension change in an individual rope on the tension distribution in the remaining ropes in the system. Unlike the presently used method, in which the desired tension distribution is obtained in a long-lasting iterative process burdened with relatively large errors of final values, the proposed method makes it possible to achieve the final tension distribution in a finite number of steps. In the case of FEM analyses, the new method can be a useful tool for determining an arbitrary distribution of tension forces in ropes via solving a system of linear equations.

Aerodynamic Performance of a New Double-Flap Wing Sail
Authors: Li Dongqin , Zhang Yili , Li Peng , Dai Jingjing , Li Guohuan 
Published: January 2020

Abstract
As a type of natural energy resource, wind power is used in the modern implementation of wind-assisted technologies as a method for reducing the fuel consumption and environmental pollution of ocean-going ships. In order to promote the full usage of ocean wind energy for cargo ships, an innovative type of ship propulsion-assisted wing sail is proposed in this paper. The propulsion efficiency of this new wing sail can be increased by enlarging its area in both the transverse and vertical directions in good weather conditions, and it can be folded up automatically in poor weather conditions, improving the sailing safety of the ship. The sail parameters relating to the gaps and rotation angles between different parts of the wing sail are compared, and the values giving the best aerodynamic performance are identified using CFD simulation technology. The results for the lift and drag coefficients for the new wing sail at different attack angles are also compared with those of traditional aerofoil sails, including an arc-shaped rigid sail and a variable-camber sail proposed in 2015. From the viewpoint of the sailing performance of the vessel, our results demonstrate that this new type of wing sail has good aerodynamic performance and can reduce fuel costs for commercial vessels.
Framework of an Evolutionary Multi-Objective Optimisation Method for Planning a Safe Trajectory for a Marine Autonomous Surface Ship
Authors: Szłapczyński Rafał , Ghaemi Hossein 
Published: January 2020

Abstract
This paper represents the first stage of research into a multi-objective method of planning safe trajectories for marine autonomous surface ships (MASSs) involved in encounter situations. Our method applies an evolutionary multi-objective optimisation (EMO) approach to pursue three objectives: minimisation of the risk of collision, minimisation of fuel consumption due to collision avoidance manoeuvres, and minimisation of the extra time spent on collision avoidance manoeuvres. Until now, a fully multi-objective optimisation has not been applied to the real-time problem of planning safe trajectories; instead, this optimisation problem has usually been reduced to a single aggregated cost function covering all objectives. The aim is to develop a method of planning safe trajectories for MASSs that is able to simultaneously pursue the three abovementioned objectives, make decisions in real time and without interaction with a human operator, handle basic types of encounters (in open or restricted waters, and in good or restricted visibility) and guarantee compliance with the International Regulations for Preventing Collisions at Sea. It should also be mentioned that optimisation of the system based on each criterion may occur at the cost of the others, so a reasonable balance is applied here by means of a configurable trade-off. This is done throughout the EMO process by means of modified Pareto dominance rules and by using a multi-criteria decision-making phase to filter the output Pareto set and choose the final solution
Review of Weather Forecast Services for Ship Routing Purposes
Authors: Życzkowski Marcin , Szłapczyńska Joanna , Szłapczyński Rafał 
Published: January 2020

Abstract
Weather data is nowadays used in a variety of navigational and ocean engineering research problems: from the obvious ones like voyage planning and routing of sea-going vessels, through the analysis of stability-related phenomena, to detailed modelling of ships’ manoeuvrability for collision avoidance purposes. Apart from that, weather forecasts are essential for passenger cruises and fishing vessels that want to avoid the risk associated with severe hydro-meteorological conditions. Currently, there is a wide array of services that offer weather predictions. These services include the original sources – services that make use of their own infrastructure and research models – as well as those that further postprocess the data obtained from the original sources. The existing services also differ in their update frequency, area coverage, geographical resolution, natural phenomena taken into account and finally – output file formats. In the course of the ROUTING project, primarily addressing ship weather routing accounting for changeable weather conditions, the necessity arose to prepare a report on the state-of-the-art in numerical weather prediction (NWP) modelling. Based on the report, this paper offers a thorough review of the existing weather services and detailed information on how to access the data offered by these services. While this review has been done with transoceanic ship routing in mind, hopefully it will also be useful for a number of other applications, including the already mentioned collision avoidance solutions.
Hybrid Finite Element Method Development for Offshore Structures’ Calculation with the Implementation of Industry Standards
Authors: Łubiński Jacek , Olszewski Henryk 
Published: January 2020

Abstract
In the design process of offshore steel structures, it is typical to employ commercial calculation codes in which simulation and evaluation of results are performed on the basis of the available standards (e.g. API, DNV, Lloyds). The modeling and solution rely on finite element methods and cover the simulation of the structure’s properties along with the influence of the marine environment – sea currents, wave and wind loading, as well as the influence of vibrations, buoyancy and accompanying mass of water. Both commercial and open source mathematical modeling software which is available nowadays allows for cost effective and flexible implementation of advanced models for offshore industrial structures with high level of credibility and safety. The models can be built to suit task-specific requirements and evaluated on the basis of the selected criterial system best suited to the needs of the customer. Examples of methodology for environmental and structural model development are presented, along with simulation results covering a wide scope of data, ranging from stress and deformation to resonant characteristics and issues of technological feasibility.

Published: January 2020

Abstract
Problems regarding the security of maritime infrastructure, especially harbours and offshore infrastructure, are currently a very hot topic. Due to these problems, there are some research projects in which the main goal is to decrease the gap and improve the methods of observation in the chosen area, for both in-air and underwater areas. The main goal of the paper is to show a new complex system for improving the security of the maritime infrastructure by means of many methods of observation – such as thermovision, optical devices, and radar systems – generally by means of an electromagnetic wave as a carrier of information in the air and acoustical methods in water. The system can be applied to the protection of maritime infrastructure as well as the coastal zone.

Blade Section Profile Array Lifting Surface Design Method for Marine Screw Propeller Blade
Authors: Król Przemysław 
Published: January 2020

Abstract
The lifting surface model is widely used in screw propeller design and analysis applications. It serves as a reliable tool for determination of the propeller blade mean line and pitch distribution. The main idea of this application was to determine the blade shape that would satisfy the kinematic boundary condition on its surface with the prescribed bound circulation distribution over it. In this paper a simplified lifting surface method is presented – in which the 3D task for the entire blade is replaced by a set of 2D tasks for subsequent blade section profiles.

Authors: Cherednichenko Oleksandr , Serbin Serhiy , Dzida Marek 
Published: January 2020

Abstract
In this paper, we consider the issue of thermo-chemical heat recovery of waste heat from gas turbine engines for the steam conversion of associated gas for offshore vessels. Current trends in the development of offshore infrastructure are identified, and the composition of power plants for mobile offshore drilling units and FPSO vessels is analyzed. We present the results of a comparison of power-to-volume ratio, power-to-weight ratio and efficiency for diesel and gas turbine power modules of various capacities. Mathematical modeling methods are used to analyze the parameters of an alternative gas turbine unit based on steam conversion of the associated gas, and the estimated efficiency of the energy module is shown to be 50%. In the modeling of the burning processes, the UGT 25000 serial low emission combustor is considered, and a detailed analysis of the processes in the combustor is presented, based on the application of a 35-reaction chemical mechanism. We confirm the possibility of efficient combustion of associated gas steam conversion products with different compositions, and establish that stable operation of the gas turbine combustor is possible when using fuels with low calorific values in the range 7–8 MJ/kg. It is found that the emissions of NOx and CO during operation of a gas turbine engine on the associated gas conversion products are within acceptable limits.
Design and Operational Innovations in Adapting the Existing Merchant River Fleet to Cost-Effective Shipping
Authors: Abramowicz-Gerigk Teresa , Burciu Zbigniew 
Published: January 2020

Abstract
Modernisation of the existing river fleet adapted for the local conditions of the Middle and Lower Vistula can be considered as a solution to slow down the progressive decrease of river transport in this area. The implementation of technical improvements, smart technologies and enhancement of transport performance may partially solve the problem of growing demand for multimodal transport of containers and oversized loads in a shorter perspective than the expected period of planned revitalisation of the river. The paper presents investigations on the modernisation of river convoys adapted to the current navigational conditions of the Lower Vistula. The different options have been discussed by the authors with river fleet operators and the best recognised solution was agreed to be the use of river convoys combining modernised motor barges and the pushed barges previously used in this area. Improvement of the transport profitability, reduction of fuel consumption, air pollution and noise can be achieved at minimum costs by modernisation of the main power-propulsion systems of outdated motor barges and the implementation of innovative steering systems on pushed barges. The demand for power-propulsion and manoeuvring performance of modernised convoys is discussed in the paper.
Appearance and Existence in Mandarin Chinese
Authors: Zhang Niina Ning 
Published: January 2020

Abstract
In Mandarin Chinese, the string of three overt elements in a row, a locative, a verb, and a nominal, asserts the existence of the entity denoted by the nominal in the location. This paper argues that the verb is contained in an adjunct, whereas the locative in its base position and the nominal establish a matrix predication relation. Thus, instead of the overt verb, the head of the matrix predicate of the construction is null. Moreover, a new analysis is provided to explain the obligatory argument sharing between the verb and the matrix predication of the construction. Furthermore, the paper argues that the agent of a transitive verb in certain types of embedded clauses needs to be Case-licensed by either the v of the selecting verb, as in an ECM construction, or a local c-commanding functional element, such as a complementizer, as in the English infinitive for construction. This Case-licensing explains why the transitive verb in the string has no agent. The research shows that the syntactic strategies to license abstract Cases in Chinese are similar to the ones found in other languages. Finally, the paper argues that the post-verbal -zhe is an adessive marker when it occurs in a non-progressive context.
