Learning Design
Opis:
Learning Design is a descriptive framework for activity structures that can describe many different pedagogical methods. It is similar to music notation, which can describe many styles of music using a common format, but Learning Design needs further research to be an effective format for sharing good teaching ideas among educators. Learning Design may also provide benefits for traditional educational research through more precise descriptions of educational innovations, which could allow for better control of confounding factors, and through rich records of student performance. Effective sharing of research-based Learning Designs has great potential for the future of teaching and learning.

Opis:
Dockside cranes must meet the relevant strength requirements that provide usefulness and not endanger the safety of their use. The vibration effect on structural safety hazard results from the impact of horizontal forces caused by the transport of goods for loading and transverse forces caused by wind, which can be dangerous for correct functioning. In addition, there are often serious effects of climate-related impacts of the environment, material fatigue, which actuates the degradation state of the object. Dynamic loads may therefor cause random effects that devastate the structures or lead to their catastrophic destruction. Recognizing the need to improve the testing methods of crane structures in order to assess their condition and assess their safety factors - this paper attempts to develop a methodology for testing the degradation of the selected portion of a construction crane - using experimental modal analysis, realized in simulation tests in the Inventor environment as well as at test stand research.

Opis:
The design of objects requiring human interaction often revolves around methods such as Human Centred Design (HCD). Whilst this is beneficial in many cases, contemporary developments of technology such as the Internet of Things (IoT), which produce assemblages of interactions, lead to the view that human centred approaches can prove problematic leading to the proposal of adopting more-than-human perspectives. This study discusses the creation of a novel board game designed to explore a more-than-human design view for IoT products and services by addressing problematic issues in relation to user data privacy and security within the IoT which arguably arise from the application of traditional HCD approaches. By embracing Object-Oriented Philosophy, The Internet of Things Board Game creates an ontographic mapping of IoT assemblages and illuminates the tiny ontologies of unique interactions occurring within these digital and physical networked spaces. Here the gameplay acts as metaphorism illustrating independent and interdependent relationships between the various ‘things’ in the network. The study illustrates how critical game design can help develop potential new design approaches as well as enabling users to better understand the complex digital/physical assemblages they create when utilising IoT products and services in their everyday lives.

Opis:
Inspired and led by Dr. Gregory E. Kersten, a number of research projects have been conducted at the InterNeg Research Centre. This paper intends to acknowledge Dr. Kersten’s unique role as a pioneer in e-negotiation research, particularly in exploring and integrating various elements in e-negotiations. From the design science research perspective, this paper reviews a series of relevant research works in e-negotiation modeling, system design and development, and experimental studies. This provides an integrative view of interconnected elements in this field, and also helps framing the various studies into different aspects and stages of e-negotiation research. The paper then suggests several guidelines and directions for future design science research in e-negotiations.

Opis:
Riflemen’s trainers are efficiently applied for the training of the armed forces, police, and shooting sportsmen. However, the training quality directly depends on the perfection of trainers as well as on their functional facilities. One of them is the shooting possibility by using various weapons. The new modification of a practise range is created: it’s included three types of weapons imitators for 5.56 mm G-36 assault rifle, 7.62 mm FN MAG machine gun and, 84 mm CARL GUSTAF recoilless gun. The work presents the universal dynamical and mathematical models of the one way operation pneumatic drive for recoil imitation, results of its investigation and description of the new modification of laser range for riflemen.

Opis:
Alongside other disciplines in social sciences, management researchers use mixed methods research more and more in conduct of their scientific investigations. Mixed methods approach can also be used in the field of production engineering. In comparison with traditional quantitative and qualitative research methods, reasons behind increasing popularity of mixed research method in management science can be traced in different factors. First of all, any particular discipline in management can be theoretically related to it. Second is that concurrent approach of mixed research method to inductive and deductive research logic provides researchers with opportunity to generate theory and test hypothesis in one study simultaneously. In addition, it provides a better justification for chosen method of investigation and higher validity for obtained answers to research questions. Despite increasing popularity of mixed research methods among management scholars, there is still need for a comprehensive approach to research design typology and process in mixed research method from the perspective of management science. The authors in this paper try to explain fundamental principles of mixed research method, its typology and different steps in its design process.
Obok innych dyscyplin w naukach społecznych, również w dyscyplinie nauk o zarządzaniu naukowcy coraz częściej korzystają z metod mieszanych w prowadzeniu swoich badań naukowych. Metody mieszane mogę również znaleźć zastosowanie w badaniach z zakresu inżynierii produkcji. W porównaniu z tradycyjnymi ilościowymi i jakościowymi metodami badawczymi, przyczyn zwiększającej się popularności mieszanych metod badawczych w naukach o zarządzaniu jest wiele. Po pierwsze każdy obszar w zarządzaniu może być teoretycznie związany z nimi. Po drugie w mieszanych metodach badawczych jednoczesne podejście indukcyjne i dedukcyjne umożliwia naukowcom generowanie teorii oraz testowanie hipotez w jednym badaniu jednocześnie. Ponadto zapewnia lepsze uzasadnienie wyboru metody badawczej i wyższą wiarygodność uzyskanych odpowiedzi na pytania badawcze. Pomimo coraz większej popularności mieszanych metod badawczych, nadal istnieje potrzeba kompleksowego podejścia do projektowania procesu badawczego z punktu widzenia nauk o zarządzaniu. W niniejszym artykule autorzy starają się wyjaśnić podstawowe zasady leżące u podstaw metod mieszanych, ich typologii i różnych etapów w procesie ich projektowania.

Electrotechnical Institute has been conducting research and design of transformers with nominal frequency greatly exceeding 50 Hz. Over 30 types of transformers were designed and built by the institute. This paper was elaborated basing on acquired experience in and the research results. Basing on the laws of electric machines growth, dependencies of size, mass, losses and efficiency on nominal frequency were derived. It was shown that raising the nominal frequency by multiple factor does not give much benefit. It was shown that, for the transformer mass decrease, the key factor is dissipation of magnetic materials, construction and technology of production of the core. Table 3 contains parameters of nine types of transformers designed and built in the institute. High efficiency was obtained, and in case of nanocrystalline cores, exceptionally small mass of the transformers. This paper contains practical advices and remarks regarding construction and method of production of the transformers. Brief description of the research conducted in the Electrotechnical Institute was presented. Sample results of the dissipation of several types of cores were presented.

Opis:
In this paper, knowledge workers are assumed to actively realize knowledge management tasks. They are involved in the gathering, analysis, storage and dissemination of knowledge in a way that is focused on its improvement. Therefore main goal is to present system architecture models for knowledge management in information science domain. In that domain, Design Science Research (DSR) is discussed as being very useful and adopted in this paper for knowledge management. The author applied the ArchiMate modelling language and supplemented it with the process approach and Business Process Model & Notation (BPMN) for knowledge management process presentation, as well as by the case management approach and Case Management Model & Notation (CMMN). These notations are consistent and complementary, although they have different objectives of usage.
