A Framework of A Ship Domain-Based Near-Miss Detection Method Using Mamdani Neuro-Fuzzy Classification
Authors: Szłapczyński Rafał , Niksa-Rynkiewicz Tacjana
Published: June 2018

Safety analysis of navigation over a given area may cover application of various risk measures for ship collisions. One of them is percentage of the so called near-miss situations (potential collision situations). In this article a method of automatic detection of such situations based on the data from Automatic Identification System (AIS), is proposed. The method utilizes input parameters such as: collision risk measure based on ship’s domain concept, relative speed between ships as well as their course difference. For classification of ships encounters, there is used a neuro-fuzzy network which estimates a degree of collision hazard on the basis of a set of rules. The worked out method makes it possibile to apply an arbitrary ship’s domain as well as to learn the classifier on the basis of opinions of experts interpreting the data from the AIS.
Impact Pressure Distribution on a Monopile Structure Excited by Irregular Breaking Wave
Authors: Veic Duje , Sulisz Wojciech
Published: June 2018

The problem of impact pressure distribution on a monopole structure excited by irregular breaking waves is investigated. The analysis is performed by applying a numerical model that combines potential flow model with a Navier-Stokes/VOF solution. The temporal pressure distribution is analysed for two breaking wave cases characterized by the significant difference in the steepness of the wave front. The peak impact pressures are observed in the region below the overturning wave jet where the pressure increases rapidly resulting in a peak value of the slamming coefficient equal to Cs=2π. The vertical load distribution provided by the derived model is more realistic than a rectangular shape distribution applied in engineering practice. This is because the vertical load distribution strongly depends on breaking wave shape and it is difficult to uniquely approximate such a load distribution by a rectangle.
Vertical Motions Damping Model Test of a Lifeboat Lowered Onto a Flat Sea Surface
Authors: Kniat Aleksander , Dymarski Paweł
Published: June 2018

The article presents the experiment’s results of the lifeboat model lowered with an initial speed and then released to fall onto a flat water surface. The purpose of the research is to determine the trajectory of the vertical boat motion and describe it with a mathematical model. This is closely related to determining the damping factor since the vertical motion is damped and the lifeboat gets balanced and stops moving after some time. The procedure of selecting parameters in the mathematical model to adjust to the results of the experiment was described in details. The summary describes the imperfections of the presented damping model and their probable causes.
Methods of Determination of Frictional Resistance for Prediction of Total Resistance of Inland Waterway Vessels
Authors: Kulczyk Jan
Published: June 2018

In the present paper presented are the results of prediction of total resistance of inland waterway vessels based on model test data. In scaling the resistance from model to full scale the extrapolation with two-dimensional frictional resistance formulation (without form factor) was applied, combined with different methods of determination of frictional (viscous) resistance coefficient. There were used the equations that include the effect of water depth, with and without account for pressure gradient. It was shown that limited depth of water substantially affects the frictional resistance. The results of example calculations are compared to resistance prediction made using the ITTC 1957 model-ship correlation line. Example calculations take into account the limited depth of water. Depending on the applied method of determination of frictional resistance coefficient the resultant total resistance of inland waterway vessel is higher or lower than the resistance based on the ITTC 1957 correlation line. The effect of water depth depends on the ratio of water depth to ship draught (h/T), on ship speed, and on the composition of a convoy. The extrapolation of resistance was made without including the form factor. Computations are made based on model test data for an inland waterway cargo vessel, for a kombi-type convoy of an inland waterway cargo vessel and a dumb barge, and for a convoy of two dumb barges without a pushboat.
Longitudinal Motion Due to Action of Tunnel Thrusters
Authors: Reichel Maciej
Published: June 2018

Tunnel thrusters are propulsion and active control devises that provide a side force, or transverse thrust, to support mooring operations or position keeping. They shorten the time of manoeuvring, reduce the cost of towage and since inception, manoeuvrability specifically in ports has become a lot easier. Tunnel thrusters can either be operated manually or with the help of Dynamic Positioning systems which makes it even more efficient.

Theoretically, the transverse force due to tunnel thruster action should generate only lateral and rotational motion. Therefore, it is typical and a common practice during manoeuvring simulations that the longitudinal motion due to the action of tunnel thrusters is neglected. Nevertheless, the experience of masters and pilots shows that some longitudinal motion due to the action of tunnel thrusters appears.

This paper shows some examples of turning manoeuvres carried out with bow thrusters only, i.e. no additional control devices or tug assistance have been used. The manoeuvres have been carried with minimal possible initial longitudinal nor lateral speed. Model tests have been done with the use of large manned models of VLCS, PCTC and LNG carrier, which differ in hull shape, dimensions and shape coefficients.

Results obtained from the tests confirm that the motion caused by bow thruster besides rotational and lateral motion consists additionally of longitudinal motion. Analysis of the combination of motions due to the action of tunnel thrusters have been done and some rationale for this phenomenon has been presented. Additionally a short analysis of position of pivot point during tunnel thruster test has been carried out.
Numerical Simulation of Cushioning Problem for Blunt Bodies Using Boundary Element Method
Authors: Barjasteh Mojtaba , Zeraatgar Hamid
Published: June 2018

Induced air pressure and resulting free surface profile due to air cushioning layer is studied. The study is mainly focused on 2D blunt circular bodies with constant downward speed. The problem is first solved for the air flow between the body and the free surface of the water. Then the results are employed to solve the problem for the water problem, numerically. Both air and water problem are assumed to be governed by Laplace potential equation. Depending on the induced pressure and velocity of the escaping air flow from cushioning layer, compressibility of the air is also included in the modeling. Gravitational acceleration is also included in the model. An iterative boundary element method is used for numerical solution of both air and water problems. Instantaneous pressure distribution and free surface profile are evaluated for different bodies. The results of calculation for large blunt bodies show that inviscid potential method can fairly approximate the problem for large blunt bodies. Additionally, the behavior of the air pressure for the very blunt body is impulsive and the magnitude of the peak pressure is in order of impact pressure of water entry. The obtained results are compared with analytical method. The comparison shows that as the bluntness of a body increases, the better agreement is concluded.
Parametric Comparison of Rectangular and Circular Pontoons Performance as Floating Breakwater Numerically
Authors: Tabatabaei Seyyed Mohammad Reza , Zeraatgar Hamid
Published: June 2018

Rectangular and circular pontoons are one of the most widely cross-sections used as floating breakwaters (FB). Although, there are several articles on comparison of behavior of rectangular and circular floating breakwaters however, the Authors try to show some details of difference between these two types where they have not been addressed before. To do so, transmission coefficient (Ct), as a measure of merit, of similar rectangular and circular sections is numerically compared. A computer code is developed for two-dimensional hydrodynamic analysis of floating breakwater based on diffraction theory in frequency domain in regular waves with any configuration of mooring line. The numerical method is the finite element method and validated by comparing with experimental and numerical results. Three types of rectangular sections are defined equivalent to circular section and a numerical comparison is made between 100 similar sections. The Ct versus wave frequency has been considered in detail and three new points called LMinF, LMaxF and LMaxCt are introduced. It has been shown that LMinF and LMaxF of circular section are greater and LMaxCt is much smaller than equivalent rectangular section. The LMaxCt of both sections are very dependent to new non-dimensional parameter B/D (Breadth/Draft). Although, rectangular sections are more common for floating breakwater, however the results of this study show that possibility of using circular sections must be also considered.

The Influence of Water and Mineral Oil On Mechanical Losses in the Displacement Pump for Offshore and Marine Applications
Authors: Śliwiński Paweł
Published: June 2018

In this paper mechanical losses in a positive displacement pump supplied with water and mineral oil (two liquids having significantly different viscosity and lubricating properties) are described and compared. The experimental tests were conducted by using a prototype satellite pump of a special design. The design of the satellite pump is presented in the article. The pump features and a non-circular tooth working mechanism was developed to work with both water and mineral oil. The sources of mechanical losses in such pump are also characterized in this paper. On this basis, a mathematical model of the losses has been developed and presented. The results of the calculation of mechanical losses according to the model are compared with the results of the experiment. The experimental studies have shown that the mechanical losses in the water pump are even 2.8 times greater than those in the oil pump. It has been demonstrated that the mathematical model well describes the mechanical losses both in the water pump and the oil pump. It has been found that the results from the loaded pump simulation (at Δp=25MPa) differ from the results of the experiment by no more than 5% both for oil and water.

Authors: Jakowski Damian , Dzida Marek
Published: June 2018

This paper presents characteristics and purposefulness of supporting the renewable energy sources (OZE) by means of energy stores. The main emphasis was placed on analysis of virtual energy stores available for implementation in Polish economy conditions. A role which management of Demand Side Response (DSR) may play in balancing Polish electric power system, is discussed. Implementation of such solutions together with conventional energy stores may significantly influence power supply safety by assuring continuity of electric power supply at an acceptable price. Involvement of electric power consumers (DSR) should be one of the basic solutions for power markets in Poland and Europe.

Authors: Szewczuk-Krypa Natalia , Drosińska-Komor Marta , Głuch Jerzy , Breńkacz Łukasz
Published: June 2018

The article presents results of efficiency calculations for two 560 MW nuclear cycles with high-temperature gas-cooled reactor (HTGR). An assumption was made that systems of this type can be used in so-called marine nuclear power plants. The first analysed system is the nuclear steam power plant. For the steam cycle, the efficiency calculations were performed with the code DIAGAR, which is dedicated for analysing this type of systems. The other system is the power plant with gas turbine, in which the combustion chamber has been replaced with the HTGR. For this system, a number of calculations were also performed to assess its efficiency. Moreover, the article names factors in favour of floating nuclear power plants with HTGRs, which, due to passive safety systems, are exposed to much smaller risk of breakdown than other types of reactors which were in common use in the past. Along with safety aspects, it is also economic and social aspect which make the use of this type of systems advisable.
Ranking of Toxic Compound Concentrations As Diagnostic Parameetrs of Marine Internal Combustion Engine
Authors: Zadrąg Ryszard , Kniaziewicz Tomasz
Published: June 2018

Changing selected engine structure parameters, especially fuel system parameters, affects the emission of harmful compounds in the exhaust gas. Changes in harmful compound emission are frequently ambiguous, as they highly depend on parameters controlling the combustion process. An additional problem is that simple interactions are frequently accompanied with mutual influence of these parameters. Therefore, we can say about different sensitivity of diagnostic parameters to the same excitations coming from the engine structure but executed at different loading states. When the set of diagnostic parameters is numerous and the values of these parameters are similar, there is a real problem with their correct classification, frequently based on subjective assessment by the analyst. In the article, the authors propose a methodology to classify the recorded diagnostic parameters. In earlier works by the authors [4,6,7], the information capacity index method (the Hellwig method) was proposed as the measure of diagnostic parameter sensitivity. Based on this method, a rankling of diagnostic parameters can be created which divides the set of diagnostic variables into stimulators and destimulators. Novel authors’ approach to the presented problem consists in including nominants, i.e. variables with the most favourable value for the analysed aspect of the research, in the set of diagnostic variables. This normalisation of the set is believed to be helpful for making a diagnostic decision free from analyst’s arbitrariness. The zero unitarization method can also be helpful in creating diagnostic tests.
Acquiring Epistemic Modal Auxiliaries: the Role of Theory of Mind
Authors: De Mulder Hannah N. M. , Gautero-Watzema Annette
Published: June 2018

This study considers the acquisition of epistemic modal auxiliaries (EMA) in typically developing (TD) and autistic children and the role that Theory of Mind (ToM) plays in this development. Nineteen Dutch-speaking TD children and ten autistic children received tasks assessing ToM, general linguistic ability and EMA comprehension. Results suggest that both groups have some understanding of the Dutch EMA system, but no significant differences were found between groups. However, once participants were divided into ToM passers and ToM failers irrespective of clinical diagnosis, results showed that passers performed significantly better than failers on EMA understanding. Having a good understanding of others’ mental states, as evidenced by full marks on ToM tasks, thus seems important in the acquisition of EMA.
Exploring into Graduate Research Term Papers: a Quest for Generic Disciplinary Tendencies
Authors: Darani Parviz Ahmadi , Tahririan Mohamad Hassan , Afghary Akbar
Published: June 2018

The purpose of this exploratory analysis was to capture students’ generic tendencies in the organization of original research term papers written by graduate within the same linguistic, cultural, and disciplinary territory. A model proposed by Sheldon (2011) was benchmarked against a corpus of 60 English research term paper introductions to identify the saliency of move schemes along with step and sub-step realizations. At step-level analysis, the proportion of the various steps within Move 2 (indicating a gap, adding to what is known, and presenting positive justification) exhibited a pervasive lack of rhetorical tendency that contradicted the previous genre-based findings. Such an exploration, offers implications for English for research publication purposes instruction and academic literacies based on academic conventions and norms.
Language Challenges in Global and Regional Integration
Authors: Phillipson Robert
Published: June 2018

The article analyses whether the expansion of English is adding to linguistic repertoires, or whether a process of linguistic capital dispossession of national languages is taking place. It explores the role that discourses of ‘global English’ and of English as a ‘lingua franca’ play in processes of global and regional European integration. It considers whether the linguistic capital of all languages can be made productive when in much of Europe there is a marked downgrading of the learning of foreign languages other than English, alongside the continued neglect of many minority languages. Language pedagogy and language policy need to be situated within wider political, social and economic contexts. EU schemes for research collaboration and student mobility are of limited help in maintaining linguistic diversity. The Bologna process furthers European integration but intensifies the hegemony of English. Nordic universities are moving into bilingual education, combining English with a national language. The 2006 Declaration on a Nordic Language Policy aims at ensuring that Nordic languages and English develop in parallel, that all residents can maintain their languages, and that language policy issues should be widely understood. If neoliberalism and linguistic neoimperialism are determining factors, there are challenges in maintaining the vitality of languages, and organizing school and university education so as to educate critical multilingual citizens.
Identity and Multilingualism. An Anthropological Reading of the Representation of Alterity in Literary Katabasis
Authors: Bonda Moreno , Macijauskaitė-Bonda Jurgita
Published: June 2018

In a global and multilingual society, indubitable is the importance of a reflection on the Self and the Other as defined by language. This interdisciplinary study aims at investigating, the narrative reinvention of the theoretical principles involved in the definition of the anthropological identity as expounded by Francesco Remotti. Specifically, we analyse a centenary trend in European literature identifying a peculiar form of multilingualism with the non-human and the lack of identity. From Dante’s Inferno to Joyce’s The cat and the Devil, the netherworld, its inhabitants and captives are characterized by the use of several (usually not intelligible) languages. According to this literary cliché, while the clarity and precision of a single language contributes to define a human identity, the plurality of languages is often a sign of a lost identity and of not being human anymore. It is not by chance that the verses of Dante ‘There sighs and wails and piercing cries of woe/ […] Strange languages, and frightful forms of speech,/ words caused by pain, accents of anger, voices/ both loud and faint’ are echoed in Primo Levi’s If This Is a Man. Multilingualism is the central point in Levi’s memories from the time spent in a concentration camp where ‘languages absolutely not understandable [...], the orders shouted in languages [we] were not able to recognize’ and the ‘endless Babel where everyone is shouting’ symbolize the lost human condition. Both the damned souls and the prisoners of the camp are not human anymore because they have lost their language and, with it, their identity. In our study, the comparative and hermeneutic analysis of the narrative and lexical choices adopted to represent multilingualism in European literature reveals a strong connection between human identity and the purity of language intended as a manifestation of human rationality. On the contrary, a number of recurrent diegetic choices and figures of speech seem to define the non-human as a multilingual world characterized by sighs, wails and strange languages, like the Bellsybable of Joyce’s devil.
Plurilingual Primary School Students and Their Language Use
Authors: Lujić Rea , Deda Silvija Hanžić
Published: June 2018

This case study examines the perspective of plurilingual primary school students on three aspects of their language use: code switching, positive language transfer and translation. In other words, the research question attempted to be answered in this paper is whether plurilingual primary school students use their communicative repertoires purposefully and strategically for their communication, acquisition, and learning of the languages. The research was conducted in a class of eighteen third-graders who attended an international primary school in Zagreb, with the average age of 9. Two questionnaires and a semi-structured interview were used to collect data about the students’ language background, their language use, and their motives for engaging in code-switching, positive language transfer, and translation. In this research, the majority of the participants reported code-switching, the use of positive language transfer and translation. The findings also suggest the students are aware of the benefits that accompany plurilingualism, and that most of the participants possess significant metalinguistic awareness regardless of their young age. To sum up, this case study brings a valuable insight into the plurilingual world of primary school children and the development of their metalinguistic awareness.
Analysis of Refugee Students’ Interest, Attitudes and Learning in Social Sciences Lessons from the Perspectives of Teachers and Students
Authors: Akpinar Mehmet
Published: June 2018

The aim of this study is to examine the interest, attitudes and learning of refugee students living in Turkey towards social sciences lessons from the perspectives of both teachers and students. This phenomenological study was carried out with 20 refugee students in 10 different public schools in Trabzon province, in the 2016–2017 spring term. In addition, 13 social sciences teachers working in these schools participated in the study. The participants were chosen via the purposeful sampling method of criterion sampling. An open-ended interview form was applied in the data collection phase, and the data were analysed through content analysis. The findings revealed that the social sciences teachers had problems in communicating with refugee students due to language barriers, and they were unable to apply individualized instruction with these students due to the limitations of the curriculum. It was further established that the refugee students had a particular difficulty in learning Turkish history and culture-related topics, because they were exposed to these subjects for the first time. On the other hand, it came to light that the students performed better when social sciences teachers taught their lessons using simpler terminology, assisted with visuals. As the results of the study highlight the fact that the social sciences curriculum is too intensive to allow for individualized instruction, it is suggested that additional studies should be carried out with refugee students; moreover, refugee students may be peer-educated with the help of other refugee students who can speak Turkish.
A Comparative Study of Form-Focused and Communicative Methods of Language Teaching in ESP Courses
Authors: Karimnia Amin , Khosravani Mahmood
Published: June 2018

The purpose of this study was to compare the effectiveness of the use of communicative methods and form-focused methods as implemented in English for Specific Purposes (ESP) courses. To accomplish this, two groups of management students were selected for the study. Each group consisted of 30 participants. Their level of proficiency in English and their subject matter knowledge were tested through a sample of IELTS and a pre-test. The two groups were at the same level of proficiency in both general English and English for Students of Management before receiving treatment in 20 sessions within a period of 75 days. Participants in Group A received a form-focused method with some occasional uses of their L1. In Group B, however, the participants were exposed to a communicative ESP course which exclusively relied on English the L2. After the period of treatment, the two groups were examined via a post-test. Results showed that Group B was more successful in the post-test. Moreover, the learners who were proficient in English and the subject matter achieved more from the communicative methods of language teaching in the ESP course. Findings imply that the nature of the subject matter, or whether it is theoretical or applied, could be a factor in deciding a method of language teaching for ESP courses.
Incongruity of Civil Law Terms Under Polish and British Legal Systems: A Study of Translation Methods
Authors: Kizińska Anna , Botwina Renata
Published: June 2018

The present paper introduces seven Polish and British incongruent terms referring to civil law and makes an attempt to determine the translation methods applied while forming English equivalents for the Polish terms (“mienie”, “rzecz”, “nieruchomość rolna”, “część składowa”, “część składowa rzeczy”, “część składowa gruntu”, “przynależność”). The terms under analysis are the terms that appear at the very beginning of the third section of the Polish Civil Code called “Mienie” and constitute “terms” according to Sager (1990, p.19) and “legal terms” according to the division of terms by Morawski (1980, p. 187). The definitions of the Polish civil law terms are presented beginning with the definitions of a “term” and “equivalence”. The equivalents under analysis have been suggested in the IATE database and the most globally recognised forum for translators, “proz.com”. The research involves comparing the definitions of the terms and, if possible, the suggested equivalents, checking whether the equivalents appear in texts of the sources of the law of the United Kingdom. It has been concluded that the occurrence of system-bound terms as well as the phenomenon of the incongruity of terms make the process of translation extremely challenging, and it is difficult to find the single most adequate equivalent. Furthermore, the translation methods applied while forming the English equivalents have been determined.

Published: June 2018

Bungus Bay and surrounding are one of the coastal areas with high rate of tourism activities which visited by many domestic and foreign visitors. The bay morphology that composed by a coast surrounded by hills, a weathering results of volcanic rock as the composing lithology, and a steep to very-steep slope cause this region potential to the landslide occurrence. Information regarding the landslide vulnerability zoning is severe necessary to reduce the landslide impacts in this study area. The vulnerability classification was done by employing Storie Method by which calculated the four major parameters; slope, land use, soil type, and rainfall intensity. The result shows that Bungus Bay and surrounding categorized into five vulnerability criteria, that are very low, low, moderate, high, and very high. The high vulnerability was dominated, covered about 39.33% of the study area, which followed by the moderate vulnerability about 39.20%, respectively.  These two vulnerability categories were in the lithosol soil which very sensitive to erosion. The land use such as land clearing and fields in the hilly areas is one of the major factors in triggering the landslide. In addition, the scope of the high to moderate vulnerability includes the tourism site and the settlements of Bungus Bay and surroundings. Therefore, it is very important to do mitigation actions in form of physical developments and community socialization to reduce the landslide occurrence and impacts in this area.

Graphene with its unique properties combining mechanical resistance 200 times superior to steel, exceptional electrical, thermal, quantum and optical properties apart from an enormous versatility to modify its properties, has become a "technological catalyst" that allows the drastic evolution of a series of devices and systems existing until now limited in their capacities. Its monoatomic thickness and the need for precise control in its composition and structure to exploit its properties are posing a fundamental challenge for its manufacture and application, which is requiring enormous efforts by the scientific community and the industry. Without having yet achieved precise and complete control of the manufacturing chain, there are already small-scale graphene production chains exploiting different production methods and producing graphene worldwide to feed the first generation of graphene-based devices. The energy sector in a fundamental process of transformation towards the generation and massive and sustainable supply of energy to supply an exponentially growing demand is one of the sectors in which a more immediate impact of this first generation of systems based on graphene is foreseen. The imminent commercial appearance of a new generation of storage technologies based on graphene will significantly break the technical-economic viability thresholds that were limiting applications such as mass storage of energy in electricity networks or transport applications. In subsequent waves (2020-2025), new cheaper and more efficient hydrogen and electric generation devices will increase the availability of cheap, sustainable and distributed energy. As can be seen from the increase in the number of patents in recent years in graphene-based technologies and the gradual emergence of commercial publications from the private sector, the market is in the commercial testing phase prior to commercial exploitation.

Collaborative filtering recommender system is one of the most widely used recommender systems, while it is vulnerable to shilling attack because of its openness. In recent years, many shilling attack detection methods have been proposed and achieved some results. However, with the rapid growth of data, the detection efficiency of existing detection methods can not meet the requirements. To solve the above problem, a detection algorithm based on data tracking adapted to Big Data environment is proposed. Based on two new data features, the algorithm uses extended Kalman filter to track and predict the item's rating, and detects the abnormal item in real-time efficiently. Experimental comparison shows that this algorithm has high detection rate and small time overhead.
Поняття людського потенціалу у контексті трансформаційних процесів в Україні
Authors: Yemelianova Yuliia
Published: June 2018

Проаналізовано поняття людського потенціалу в контексті системи понять, які відображають радикальні перетворення в українському суспільстві. Осягнення його концептуально-системних основ запропоновано у контексті соціологічних концепцій Т. Заславської та Н. Паніної, а також філософських доробок С. Дацюка. Доведено, що словосполучення «людській потенціал» (Г. Беккер, Т. Шульц та ін.) як термін, що позначає якість будь-якої зі складових частин руху планетарного соціального простору, отримує нове наповнення у вказаних соціологічних концепціях. На відміну від інших учених, які акцентують увагу на соціально-економічному складнику в змісті поняття людського потенціалу, Т. Заславська, Н. Паніна, С. Дацюк наполягають на універсальності концепту «людській потенціал», що дає змогу визначити напрям соціального руху. Поняття людського потенціалу набуває значення концепту, який розкриває якісну соціально-культурну характеристику суспільства й містить у стислому вигляді програму необхідних і можливих перетворень у всіх сферах життя населення сучасної країни. У цьому факті автор убачає продовження класичної традиції аналізу проблеми людського капіталу (Т. Шульц, Г. Беккер, Е. Денісон, Дж. Кендрик, Дж. Коулман) як проблеми соціокультурного розвитку людини.

У контексті такого розвитку людства стає помітним посилення ролі ціннісно-нормативної системи регуляції та консолідації суспільства в розвинених країнах світу. Україна, яка прагне до фундаментальних змін, має досліджувати швидкість соціальної адаптації особи, соціальних інститутів, ціннісно-нормативної системи, котра зараз народжується в суспільстві. У цій новій системі активний капітал будь-якої людини або спільноти має бути сформований не лише як актуальна, але й потенціальна цінність, або як «трансгуманістичний потенціал».
Соціальна діагностика міста Луцька в рамках розробки стратегічного плану його розвитку

Залучення громади до процесу розвитку міста є першим кроком у діагностиці його проблем, переваг, особливостей тощо. Одним із таких кроків стало соціологічне дослідження «Основні напрями та перспективи розвитку міста Луцька», проведене лабораторією соціологічних досліджень СНУ ім. Лесі Українки (грудень 2016, N=656, помилка не перевищує 5 %). Згідно з результатами опитування, лучани найбільше пишаються комфортністю міста та його чистотою, у розвитку міста зорієнтовані на підтримання порядку, тобто стабільність, стурбовані проблемами демографічного характеру й не переймаються інноваціями. Попри свою традиційність, населення вже відреагувало на відтік молоді та потребу особливого соціального включення людей старшого віку, указавши на ці проблеми як на найбільш важливі. Відтік міської молоді пов’язаний не стільки з освітньою міграцією, скільки з неможливістю реалізувати себе за місцем проживання. Цілком конкретні плани є в наймолодших (16–22) та професійно сформованих (32–41), у лучан з вищою освітою та науковим ступенем. Такі наміри залежать від фінансового стану сім’ї: із його зростанням збільшуються інтенції зміни місця проживання; а от конкретні плани мають ті, у кого полярні фінансові можливості. Цікаво, що наміри полишити місто мають більшою мірою ті, хто проживає в ньому до 10 років; період у 10 років є достатнім для професійної реалізації, тому нестача можливостей для професіоналів сприятиме лише тому, що вони розглядатимуть Луцьк як місце здобуття фахової освіти з подальшою професійною міграцією, як транзитний населений пункт. Лучани дуже люблять своє місто, та лише наймолодші й найстарші відчувають особливу патріотичну настанову. Соціальна діагностика стану міської спільноти є вкрай необхідною задля прийняття рішень в управлінні містом.
