Opis:
The main reason, to take this subject was self-perception of the problems arising from the perception and definition of the operating factors in the art of war, to potential military operations against the so-called Islamic State. Operational factors do not have a clear source of their definition and perception of the art of war. Their importance in the art of war was and is treated in many cases instrumentally, their aspect of the phenomenon described operations or attributed to them only part of the description of environmental assessment to guide future actions. Analysis of the importance of operational factors indicating their wider range and finds its justification in the development of operational thinking in the art of war. It should be stressed that the ability to think of operating a psychological category entity associated with the development of thinking and mutual understanding. While the combination of thought process entity with its subject provides a reasonable basis for the use of the concept of thinking operating in the art of war. The thinking process operating relates to compounds and the relationship between perceived material objects of art of war and the influence of these relations on the preparation and organization of effective action. Therefore operational factors are the basis for the development of operational thinking in the art of war. Identification of the material objects of art of war is essential to perceive the relationship produced. You must have the awareness that in practice this means the correct identification of the area of operations and precise description of the parties, fighting. The study formulates assumptions of contemporary perception and interpretation of operational factors as the process of initiating any military action. It must be concluded that the accepted scope and structure (structure) of the work was determined the nature of the problems under consideration.

Opis:
The paper provides a comprehensive presentation of the influence of operating parameters on the tribological properties of the wheel-rail couple. Apart from wear and a friction coefficient, the tribological properties also comprise stereological parameters of flaky wear products. The tribological tests were carried out according to an experimental plan, which took account of the complex influence of operational factors on the size and shape of flaky wear products. This enabled defining the type and intensity of wear, depending on the variable operational parameters. In order to explain the wear mechanism, quantitative, qualitative, and profilographometric metallographic examinations were made.

Opis:
This paper presents human and operational factors related to risk assessment during the operations of crude oil, petroleum products, and liquefied gas transfer between ships, called Ship to Ship (STS) operations. The lessons learned from accidents during STS when both ships are underway show that the most frequent accidents occur due to ship handling errors. Several influencing factors have already been identified, however there is still a need to investigate the human factor. Both human and operational factors are interrelated as the operational factors influence the human stress level. This paper identifies the stressors related to the external pressures imposed on the ship’s staff, which can be limited to improve safety. The preliminary study of the influence of particular elements of human factors, e.g., personality traits and stress levels, on the probability of ship handling error is presented.

Opis:
Diagnostyka obiektów mostowych ma szczególne znaczenie w odniesieniu do przepraw sieci ciepłowniczej, gdzie stabilność konstrukcji nośnej jest głównym gwarantem bezawaryjnego transferu energii cieplnej przez rzekę. Jednym ze szczególnie wrażliwych elementów tego typu mostów jest nierównomierne przemieszczanie się ich elementów składowych spowodowane czynnikami eksploatacyjnymi i atmosferycznymi. W tym zakresie nieocenione wydają się okresowe pomiary geodezyjne przepraw mostowych dające obraz występujących na nich przemieszczeń. Artykuł obejmuje ocenę tachimetrycznych pomiarów przemieszczeń ciepłowniczej przeprawy mostowej, w oparciu o kilka serii obserwacji mostu wiszącego, zlokalizowanego w północno-wschodniej części Poznania. Pomiary poprzedzono wstępną analizą dokładności. Do oceny odkształceń mostu przyjęto 64 punkty kontrolowane, zlokalizowane parami na konstrukcji i odciągach oraz 3 punkty odniesienia znajdujące się poza badanym obiektem. Wykonano trzy serie pomiarowe i każdą z nich porównano z pomiarem odniesienia z 2010 roku. Wyniki analizy przedstawiono w postaci tabelarycznej, jako przemieszczenia poziome i pionowe od stanu bazowego. Wykazano, że uzyskane parametry dokładnościowe pozwalają na wiarygodną ocenę stanu geometrycznego tej klasy konstrukcji.
Diagnostics of bridge structures are of particular importance with regard to heating network crossings, where the stability of the supporting structure is the main guarantor of failure-free thermal energy transfer across the river. One of the particularly sensitive elements of this type of bridges is the uneven movement of their components caused by operational and atmospheric factors. In this respect, periodic trigonometric surveys of bridges seem to be invaluable giving an image of the displacements occurring on them. The article focuses on the estimation of displacement surveys of the heating bridge crossing, based on several series of observations of the suspension bridge, located in the north-eastern part of Poznań. The measurements were preceded by a preliminary analysis of accuracy. To assess the deformation of the bridge, 64 natural controlled points were selected, located on both sides of the structure and supporting ropes, and 3 reference points located outside the tested object. Three measuring series were made and each was compared with the reference measurement from 2010. The results of the analysis are presented in tabular form as horizontal and vertical displacements from the base state. It was shown that the obtained accuracy parameters allow for a reliable assessment of the geometrical state of this class of construction.

Opis:
Marine transportation is a critical component of global trade and commerce, with ports serving as key nodes for the movement of goods and people. However, navigating these ports can be hazardous, with the potential for accidents and incidents that can lead to loss of life, environmental damage, and economic disruption. This study investigates the impact of socioeconomic factors on the operational risk assessments and adoption of innovative navigational aids for better safety among marine pilots in Lagos ports. A mixed-methods approach is employed, combining surveys and interviews to collect data from a sample of marine pilots operating in Lagos ports. The study focuses on the decision-making process of marine pilots in high-risk environments, exploring how factors such as education level, income, and experience might influence their risk assessments and willingness to adopt new technologies. The study's findings have important implications for policies and programs aimed at promoting safer navigation practices in Lagos ports and improving the overall safety of marine operations. The results can also inform the design of training and education programs for marine pilots, as well as the development of new technologies and tools to support safe navigation.

Opis:
Kaizen has long been known as an improvement philosophy that starts with small frequent changes to make larger changes in production. These changes come from the ideas and creative thinking of employees to ensure that the production conditions and processes are continuously improved. However, Kaizen not only helps motivate employees to think creatively with effective methods and skills, but it also helps them develop their capabilities, personality, and good work habits. The purpose of this paper is to show a new approach to human resources quality improvement through the Kaizen philosophy as a sustainable and active strategy to improve work performance. With analytical research on the relationship between Kaizen implementation, human resources quality improvement, and production efficiency and exploratory research on particular cases in manufacturing enterprises in Vietnam, the authors point out changes in production efficiency and human capacity before and after implementing improvement (Kaizen) projects. The paper finds significant changes of employee capability (Kaizen practitioners) after evaluating the human resource development process on the basis of six indicators of two groups (namely capacity development, personality development) and a set of criteria using a 5-point scale. In addition, the paper proposes a PDCA based framework with 12 contents corresponding to stages of the human resource development. This paper extends theories related to Lean Manufacturing or Kaizen, highlighting how philosophy of Kaizen has hard and soft impacts on the improvement of performance and human resources.

Opis:
The IMO has adopted Energy Efficiency Design Index (EEDI), Ship Energy Efficiency Management Plan (SEEMP) and Energy Efficiency Operational Indicator (EEOI) in order to reduce GHG emissions from international shipping. And, the shipping industry is required to develop and improve the energy saving ship operation technologies to meet the above IMO guideline. The weather routing is one of the energy saving navigation technologies and widely adopted by oceangoing merchant ships. The effectiveness of the weather routing mainly depends on the accuracy of weather forecast data and the ship’s propulsion performance prediction. The propulsion performance in the actual sea is usually predicted using the Self Propulsion Factors obtained by model tests. It is necessary to understand the propulsion performance characteristics in the actual sea conditions for the improvement of propulsion performance prediction. From the above points of view, the authors performed full‐scale experiments using a training ship in order to investigate the propulsion performance characteristics in the actual sea. This paper describes the analysis results on the characteristics of Power Curves and Self Propulsion Factors under various weather and sea conditions.
