Opis:
Last decades the contextual approach became an important methodology of analysing information processes in the dynamic environment. In this paper we propose a context management framework suitable for secure network services. The framework allows tracking the contextual information from its origin, through all stages of its processing up to application in security services protecting the secure network application. Besides the framework's description, an example of its application in constructing secure voice call network service is given.

Opis:
Data collected through an online survey and through a number of detailed company assessments throw light on the relative strengths and weaknesses of different elements of Knowledge Management (KM) frameworks as applied globally. The online survey –a quick self-administered test, shows the strongest elements within the framework to be Technology and Behaviors and Culture. The weakest elements are KM Governance and KM Roles. The assessment – a detailed diagnostic process based on in-depth interviews, shows the strongest elements within the framework to be Technology and the Discussion of Knowledge. The weakest elements are KM Governance and KM Roles. A comparison of the results from the two sources is reassuringly close. More data may allow a more detailed analysis. Preliminary results suggest that national culture may influence the development of Knowledge Management Frameworks, with a correlation between strong Individuality and weak KM Governance and Roles.

Opis:
The purpose of the analysis was to determine the degree of use of renewable energy sources in Poland in comparison to other EU countries. The article presents the degree of use of renewable energy sources in Poland against a background of European Union countries together with the quantitative use of renewable energy sources in Poland, since 2010. Poland, like other EU countries, aims at meeting its obligations towards the energy union policy and achieving the target for energy from renewable sources by 2020, in accordance with the adopted EU strategy “Europe 2020”. The results and ways of achieving the goal by Poland were presented, as well as the breakdown of Member State contributions, which are the sum of EU-level goals by 2030. Research was based on secondary data obtained from the EU statistical agency Eurostat. The publication uses, among others: analysis of domestic and foreign literature sources and analysis of secondary data expressed in real values, the results of which are presented in tabular form. For the purposes of this publication, a method of targeted selection of quantitative parameters was used, which will allow an analysis and comparison of the degree of renewable energy development in Poland and the EU. The analyzes covered the years 2010-2017. The analyzes carried out indicate that the slowdown or growth in achieving the goal is largely influenced by current economic development or slowdown, expenditure on supporting renewable energy policy, administrative procedures and current country policy. Trends in the use of renewable energy depend on, among others the above factors.
Celem analizy było określenie stopnia wykorzystania odnawialnych źródeł energii w Polsce na tle pozostałych krajów Unii Europejskiej. W artykule zaprezentowano stopień wykorzystania odnawialnych źródeł energii w Polsce na tle krajów Unii Europejskiej wraz z ilościowym wykorzystaniem OZE w Polsce od 2010 roku. Polska, jak i pozostałe kraje UE, wypełnia zobowiązania względem polityki unii energetycznej oraz realizuje cel w zakresie energii ze źródeł odnawialnych do roku 2020, zgodnie z przyjętą strategią UE „Europa 2020”. Przedstawiono wyniki i sposoby osiągania celu przez Polskę, a także omówiono podziały wkładów państw członkowskich, które stanowią sumę celów na poziomie UE do 2030 roku. Badania zostały przeprowadzone na podstawie danych wtórnych pozyskanych z unijnej agencji statystycznej Eurostat. Wykorzystano m.in. analizę źródeł literatury krajowej i zagranicznej oraz analizę danych wtórnych wyrażonych w wartościach realnych, której wyniki zaprezentowano w formie tabelarycznej. Na potrzeby publikacji wykorzystano metodę doboru celowego parametrów ilościowych, które umożliwią dokonania analizy i porównania stopnia rozwoju OZE w Polsce i UE. Analizy objęły lata 2010-2017. Dokonane analizy wskazują, że na spowolnienie lub wzrost w osiąganiu celu wpływ mają w dużym stopniu: aktualny rozwój lub spowolnienie gospodarcze, nakłady na wspieranie polityki OZE, procedury administracyjne oraz aktualna polityka kraju. Tendencje w wykorzystaniu OZE zależą bowiem m.in. od ww. czynników.

Celem artykułu jest omówienie publikacji Międzynarodowej Agencji Energetyki Atomowej, pt. „Zarządzanie projektami elektrowni jądrowych”, która przedstawia ważne aspekty w zarządzaniu projektami w energetyce jądrowej. Ponadto została omówiona specyfika zarządzania projektami w energetyce jądrowej. W artykule przedstawiono również dedukcyjną metodę wnioskowania naukowego. Publikacja zawiera informacje na temat wdrożenia ram zarządzania projektami w ramach projektów jądrowych. Jest ukierunkowana na zwiększenie zdolności państw do planowania i wdrażania programów energetyki jądrowej. Tworzenie ram związanych z zarządzaniem projektami może doprowadzić do wspólnego pozyskiwania doświadczenia z wybranymi procesami, efektywniejszego ich wykorzystywania oraz wprowadzania na bieżąco usprawnień. Wprowadzenie odpowiedniego systemu zarządzania musi być zintegrowane z systemem zarządzania korporacyjnego organizacji, środowiskiem, w którym zachodzą wszystkie procesy i procedury projektowe. Kluczowe jest dobranie odpowiedniej metodyki i korzystanie z właściwych wytycznych, które pokazują, jak powinno się zarządzać projektami. Specyfika technologii jądrowej i zarządzania projektami jądrowymi to dostarczenie nie tylko gotowego obiektu, lecz także zrównoważonego rozwiązania, które może być zarządzane przez cały cykl życia projektu przy zaangażowaniu innych interesariuszy.
The paper aims to discuss the publication by the International Atomic Energy Agency titled ‘Management of Nuclear Power Plant Projects’. The publication provides information on how the project management framework for nuclear projects should be put in place. It is intended to enhance the capabilities of individual countries to plan and implement nuclear power programmes. By creating the framework for project management, the stakeholders may together acquire experience in selected processes, use it more effectively and improve the outcomes. The implementation of an adequate management system must be integrated with the corporate management system of an organization. Project management system is integrated with the environment hosting all project processes and procedures. The selection of adequate methodology and using adequate guidelines for project management are crucial. The specificity of nuclear technology and nuclear project management consists not only in delivering a finished product but in delivering a sustainable solution that can be managed throughout the life-cycle of the project and is able to engage other stakeholders.

Opis:
The main purpose of this study is to examine the relationship between organisational culture (OC) and Total Quality Management (TQM), and the influence of TQM implementation on organisational performance improvement within the context of the Vietnamese construction industry. A survey was conducted with 104 respondents from Vietnamese construction firms, using validated survey instruments developed in past research. Analysis techniques include cluster analysis and Structural Equation Modelling. Findings showed that Vietnamese construction firms are dominated by clan and hierarchy cultures rather than adhocracy and market cultures according to Competing Value Framework (CVF) of OC classification. urthermore, it was found that organisations dominated by either clan or adhocracy cultures could provide a favourable environment for successful TQM implementation, whereas this is not the case for those dominated by both market and hierarchy cultures. This study also confirmed the significant and positive relationship between TQM implementation and organisational performance improvement.

Opis:
Aim: As part of the recent economic and financial crisis management in the EU new regulatory measures have been adopted which are of relevance for company law and corporate governance. Although the modalities of corporate governance are primarily determined by companies themselves, the establishment of basic national and EU level rules is required so that minimum standards are respected in the public interest. With regard to EU competences, they pertain to full implementation of and safeguarding proper functioning of the EU internal market (Article 3(3) TEU and Articles 26-27 TFEU). The purpose of this paper is to analyse EU regulatory measures in the field of corporate governance with a view to their potential positive impact on sustainable functioning of European companies, notably in the financial sector, and thus also the stability of the financial system at large. Design/research methods: The applied research methodology includes a combination of theoretical and analytical methods. The paper is based on a review of relevant literature and an analysis of EU regulatory measures pertaining to inter alia new capital requirements for financial institutions, shareholder’s involvement and risk management. Conclusions/ Findings: It is submitted that, at least in theoretical terms, the analysed regulatory measures have a potential of improving sustainability of single companies, thereby translating into improved reliability of the whole financial system, also by way of reducing the risk of moral hazard of failing banks counting on public money injections.Implications/ Limitations of the research: The real impact on sustainability may, however, only be assessed once the discussed EU measures have been fully implemented or, as the case may be, where and on condition that they are fully endorsed by the companies themselves. In that regard, the theoretical and analytical methods applied in this research prove insufficient to provide a fully satisfactory answer to the research question, with the real impact of the discussed measures on sustainability being a potentially interesting field of study on the basis of a sample of system relevant financial institutions in the years to come.

Opis:
This paper presents an original information system supporting the management of an agricultural holding codenamed AGMS (Agro-Management System). This system was created in C# language, using ASP. NET MVC programming technology. The application database layer was supported by SQL Server and Entity Framework technology. The creation of the program's views enabled such languages as HTML 5, CSS3 along with Bootstrap library and Javascript with dedicated Knockout.js library. The development of the system was preceded by an analysis of requirements, in accordance with software engineering procedures. The documentation created at this stage in the form of UML diagrams was prepared in Microsoft Visio. The AGMS program presented in this article is a developmental version, so all its functionalities are not yet fully implemented. The user can use the current version of the software to map fields, manage events related to individual fields and, among other things, obtain information on pests and weeds. The article also describes the concept of the final version of the program, which should include modules implementing simple methods of artificial intelligence in the field of image recognition and decision support.
Zaprezentowano autorski system informatyczny wspomagający zarządzanie gospodarstwem rolnym o nazwie kodowej AGMS (Agro-Management System). System ten został wytworzony w języku C#, w technologii programistycznej ASP.NET MVC. Warstwa bazodanowa aplikacji została obsłużona przez SQL Server oraz technologię Entity Framework. Wytworzenie widoków programu umożliwiły takie języki jak HTML5, CSS3 wraz z biblioteką Bootstrap a także Javascript z dedykowaną biblioteką Knockout.js. Opracowanie systemu zostało poprzedzone analizą wymagań, zgodnie z procedurami inżynierii oprogramowania. Powstała na tym etapie dokumentacja w postaci diagramów UML została przygotowania w programie Microsoft Visio. Program AGMS prezentowany w niniejszym artykule jest wersją rozwojową, a zatem jego wszystkie jego funkcjonalności nie są jeszcze w pełni zaimplementowane. Użytkownik korzystając z aktualnej wersji oprogramowania ma możliwość mapowania pola, zarządzania zdarzeniami dotyczącymi poszczególnych pól, a także m.in. może zasięgać informacji o szkodnikach czy chwastach. W pracy opisano także koncepcję finalnej wersji programu, w której powinny znaleźć się moduły implementujące proste metody sztucznej inteligencji w zakresie rozpoznawania obrazów i wspomagania podejmowania decyzji.

It will be a new approach that BIM’s capital project lifecycle management (CPLM) applied to the yacht industry. This paper explored the feasibility of applying the principles and rationales of BIM for capital project lifecycle management in luxury yacht design, engineering, fabrication, construction and operation. The paper examined the premises and backbone technology of BIM. It then evaluated leading naval engineering and shipbuilding software applications and their development trends from the functional lens of BIM. To systematically investigate a BIM-based approach for capital project lifecycle management (CPLM) in the luxury yacht industry, the paper proposed and outlined an implementation framework. A case study and a student competition use case were discussed to delineate the core constituents and processes of the proposed framework. The case of BIM was reviewed. Through the domestic custom luxury yacht design and prototyping student competition, the application of this framework in educational research is demonstrated and the initial quantitative assessment of the framework is carried out. Conclusions: a BIM-based CPLM implementation framework can help the luxury yacht industry capitalize on the global transformation to an information-centric and data-driven new business paradigm in shipbuilding with integrated design, manufacturing and production.

Opis:
Safety is generally characterised as the state of being “safe”, the condition of being protected from harm or other non-desirable consequences. One effective way of achieving it is to implement a safety management system (SMS). SMS should be seen as an aggregate strategic aspect of standard business management, understanding its high priority to safety. This article describes and illustrates SMS in aviation, focusing on the similarities and differences in the system approaches adopted by selected Civil Aviation Authorities (CAAs) with the primary focus on the safety level. The main goal is to provide a structural comparison of the system framework within individual CAAs and its explanation in safety-related documents. This article also dealt with the chosen safety approach (reactive, proactive and predictive) and safety performance indicators (SPIs), forming a quality and effective safety system that maintains an acceptable safety level. Finally, this article is mainly based on datasets publicly available through the International Civil Aviation Organisation, Transport Canada, Civil Aviation Safety Authority Australia, Federal Aviation Administration, UK Civil Aviation Authority, Civil Aviation Administration of China and Civil Aviation Authority of New Zealand websites and documentation related to safety.

Opis:
The European Union’s Water Framework Directive introduced a new approach to the system of water management in Europe by nominating the river basin district as the basic unit in water management. While its transboundary character aims to better manage natural resources, its design and implementation carries several challenges due to its weak integration of various bordering effects related to administrative boundaries that strongly affect the directives’ implementation. Based on a comparative document based case study of two river basin districts – the International Oder River Basin District (IORBD) and the International Torne River Basin District (ITRBD) – the paper scrutinizes the effects on the implementation processes of the directive and aims to draw attention to identify the differences that derive from various socio-spatial settings during the first cycles of water management plans from 2009 to 2015. By thematically comparing biophysical characteristics, cross-border cooperation, cultural and administrative borderingprocesses the study displays a mismatch between the directives aims for transboundary governance and the actual governance processes which are hampered by a variety of conflicting bordering processes.

The article is devoted to the analysis of the experience of the European Union countries and the development of recommendations for improving the centralized model of public procurement management in Ukraine. The article is focused on clarification of the basic provisions of normative acts, which are the basis for the functioning of a centralized procurement organization, the State Institution «Professional Procurement». This applies to the Law of Ukraine «On Public Procurement», the Resolution of the Cabinet of Ministers of Ukraine «On the Implementation of a Pilot Project on the Organization of the Activities of a Centralized Procurement Organization» and the Order of the Ministry of Economic Development and Trade of Ukraine, ac-cording to which the functions of the Centralized Procurement Organization (herein-after referred to as the Central Depository) are entrusted to the State institution «Professional purchases». It has been established that centralized procurement is not necessarily carried out through a specialized organization. For these purposes, both, state limited liability companies and independent agencies (the structure of which is very similar to the structure of private companies) can be formed. Based on the experience gained, recommendations for the improvement of the Ukrainian centralized procurement organization were developed by the State Institution «Professional Procurement». In particular, it is proposed to legislate this institution with certain powers to monitor the market, to finance the work to use the customer's payment of a fixed advance payment for each procurement procedure and to use open framework agreements when conducting procurement procedures.

Opis:
The paper is focused on nonmonotonicity in trust management models which provide access control mechanisms for distributed systems. The work explains what decentralised systems are, defines a notion of security model nonmonotonicity, presents its types and points out factors that causes trust management model to become nonmonotonic. A result of this analysis is a model for credential revocation in the RT Framework trust management model. When security model allows for credential revocation, it becomes nonmonotonic. Presented model allows to turn it to be temporally monotonic. It allows policy authors to define constraints for roles, and applies those values to credentials. When credential does not comply to defined requirements, it is disregarded. A model is evaluated against sample scenario, which demonstrates how it can be applied to real-life use cases.

Long-term observations of Upper Vistula tributaries, made by the author, showed that the narrowing and straightening of rivers and their floodplains resulted in accelerated riverbed erosion and the increase of flood risks. River floodplains are widely acknowledged as being very important for biodiversity, therefore by their narrowing they lose their natural patterns and, as a consequence, decline in habitat and species diversity. In the last years a new approach in river management and engineering appeared: the EU Water Framework Directive constitutes an important step for more ecological river training. In consequence an increasing number of restoration projects have been initiated in the last years. In the present paper the author tried to study and check the possibilities of flood plain widening upstream of the town of Nowy Sącz situated along the Dunajec River (km: 111.900 – 107.500), where devastated lands occurred. In the urban area of Nowy Sącz the levees distance was left unchanged. For the new conditions the numerical simulation by 1D mathematical model Rubarbe was carried out. The obtained results showed a significant decrease in the flood peaks upstream of Nowy Sącz and lesser decrease in the town.
