The Integrated - Operational Model of Managerial - Legislative - Sports Training of Specialists in the Field of Physical Culture

Currently, the organization of the interaction of higher education institutions and social partners, responds to the "modern challenges" of the information society and knowledge, determining the development trends of the vocational education system. The analysis, generalization and systematization of the literature, the study of modern pedagogical experience, made possible the determination of conceptual bases and approaches for building a pedagogical integrated - operational model of managerial - legislative - sports training of specialists in the field of physical culture and sports. The model is based on systemic approaches, individual activities and research of specialists, the principles and objectives being focused on inclusive skills training and on the orientation of professional training on motivational, value, cognitive and reflexive components. The pedagogical integrated - operational model of managerial - legislative - sports training involves a certain organization of the educational process and the creation of individual or group pedagogical conditions for professional development focused on ways to solve problems identified in professional context, as well as focusing on creative achievement and innovation of professional activities. The professional training of future specialists in the field is focused on an internal process (because a person can acquire skills or learn through his own activity) and an external process (by creating adequate informational and educational conditions). In order to design the integrated - operational model of managerial - legislative - sports training of future specialists in the field, it was important to determine the essence of professional training, its place in the professional development of the personality of a specialist in the field and to identify factors influencing this process.

Exploring workplace dignity from managerial lens

Purpose Understanding managers’ experiences of workplace dignity (WPD) is critical to working with others in an organization. However, there is limited research available on this subject. This study aims to expand the knowledge of WPD by exploring managers’ understanding of WPD and their experiences of both affirmation and denial of dignity at work. Design/methodology/approach Critical incident technique (CIT) has been used to explore the themes related to managers’ perceptions of WPD through their lived experiences. Affective event theory supports the use of CIT in the current study context. Findings Findings unfolded many new aspects of WPD, which have not been explored in the past. An exploration and analysis of the three research questions related to managers’ understanding, affirmation and denial experiences of WPD have added new insights to the existing literature. These have been further segregated under the following four main factors: internal, external, process and feelings. Finally, the authors conclude that external factors that arrive during exchange relationships play an important role in managers’ understanding and experiences of WPD in India. Originality/value To the best of the knowledge, this is a seminal study to have explored managers’ understanding of WPD in India. It aims to add to the literature by enriching the construct of WPD. Practical implications include a deeper managerial understanding of the affirmational practices and factors which will positively impact WPD.

Karakteristik Perubahan Lingkungan Akhir Plistosen - Holosen di Dataran Rendah Aluvial dan Pantai Wilayah Demak, Kudus, Jepara, Pati dan Sekitaranya

ABSTRAKWilayah dataran aluvial hingga pantai daerah Demak, Kudus, Jepara, Pati dan sekitarnya ditutupi endapan sedimen Holosen yang terdiri atas kerikil, pasir, lempung, lanau, dan bongkah batuan gunungapi. Penelitian dilakukan dengan analisis sedimentologi dan stratigrafi terhadap 37 pemboran berskala 1 : 100 dengan ketebalan sedimen antara 0,8 - 18 meter. Berdasarkan korelasi data hasil pemboran diketahui bahwa sedimen Holosen di wilayah ini dapat dibedakan dalam tiga interval proses pengendapan (IPP A- C). Perubahan sedimen secara vertikal dapat diwakili oleh setiap sub-IPP yang merupakan hasil dari proses eksternal sesuai perubahan iklim, fluktuasi muka laut, tektonik dan aktivitas gunungapi. Dari hasil analisis stratigrafi diketahui bahwa perubahan lingkungan pengendapan pada daerah penelitian berhubungan dengan aktivitas proses eksternal di cekungan ini. Peranan proses eksternal ini diharapkan menjadi variabel dalam perumusan kebijakan pengelolaan lingkungan di wilayah Demak, Kudus, Jepara, Pati, dan sekitarnya.Kata kunci: fluktuasi muka air laut, Holosen, lingkungan, tektonik, perubahan iklimABSTRACTThe alluvial plain to the coast of Demak, Kudus, Jepara, Pati, and its surroundings is covered with sedimentary Holocene deposits consisting of gravel, sand, clay, silt, and volcanic rock boulders. The study used sedimentology and stratigraphic analysis of 37 drilling points with sediment thicknesses between 0.8-18 meters. Based on the correlation of drilling results, the Holocene sediments in the area of research can be distinguished in three deposition process (IPP) intervals. Vertically, sediment changes can be represented by each sub-IPP which are the result of external processes according to climate change, sea-level fluctuations, tectonics, and volcanic activity. From the results of the stratigraphic analysis, the changes in the depositional environment in the study area are related to external process activities in the basin. The effects of this external process are expected to be a recommendation in the future environmental development in the Demak, Kudus, Jepara, Pati, and its surroundings.Keywords: sea-level fluctuation, Holocene, environment, tectonic, climate change

Factors of social orientation on physical activity and methods of their application in the process of formation of motives of physical activity of the person

Social and valuable orientation on health activities is formed and regulated with the help of influence on a person (social group) by certain factors. The overall understanding the word as factor is the main reason; moving force of some process; some relations and relationships; this is that is conditioned objective necessary or subjective desired result. Factors of health activities are connected at overall system which has own construction and functions. Their main elements are two groups of factors: social and natural ones. The action of natural factors is connected with biological nature of a human and dependence from environment. Social factors are economic, social and political, organizational and leading as well as psychological and pedagogical and moral reasons of health activities. So there are three united processes of a magnet of humans to lessons of physical exercises: 1) the process of external influence of a society on a person that is social orientation on health activities; 2) the external process of understanding a person an influence of natural or social environment that is orientation of health activities; 3) the result of orientation as the done motives that is social and valuable orientation on this activities. Abovenamed processes and phenomena are the social orientation on health activities; this activities is an influence of a society or social group on certain subject to appear social and valuable orientation on lessons of physical exercises and further development of physical culture as a whole. At a mechanism of a social orientation the economic and social and political factors have a certain influence on forming given orientation. For providing their certain influence at a structure of social orientation there are special group of factors – factors of orientation on health activities. These factors are special organized actions which are complex reason of certain kind of relation to activities. When magnetizing a subject to lessons of physical exercises with the help of factors of orientation there are such stages: grounding for this subject a necessity at health activities; opening methods and means of its organization; understanding such activities themselves when taking part at it; working and widening results of all previous stages. Such for determinates a structure of factors of orientation according to their content and principle of directed action.

Investigations of the Absorption Front in High-Speed Laser Processing Up to 600 m/min

High processing speeds enormously enlarge the number of possible fields of application for laser processes. For example, material removal for sheet cutting using multiple passes or precise mass corrections can be achieved by means of spatter formation. For a better understanding of spatter formation at processing speeds of several hundred meters per minute, characterizations of the processing zone are required. For this purpose, a 400 W single-mode fiber laser was used in this study to process stainless steel AISI 304 (1.4301/X5CrNi18-10) with speeds of up to 600 m/min. A setup was developed that enabled a lateral high-speed observation of the processing zone by means of a glass plate flanking. This approach allowed for the measurement of several dimensions, such as the penetration depth, spatter formation, and especially, the inclination angle of the absorption front. It was shown that the loss of mass started to significantly increase when the absorption front was inclined at about 60°. In combination with precise weighings, metallographic examinations, and further external process observations, these findings provided an illustration of four empirical process models for different processing speeds.

Comparison of Plug Flow and Multi-Node Stratified Tank Modeling Approaches Regarding Computational Efficiency and Accuracy

Residential water heaters contain water stratified by temperature-driven density differences. This implies that a water tank can reach a state in which the top and bottom sections have different temperatures, unless mixing happens. A high degree of thermal stratification can improve the efficiency of some water heaters, by saving the amount of energy required for the heat-up process. Studies of stratification became popular in the 1970s and it remains an active research topic today. The research has led to the development of different models and techniques to better predict and define a stratified tanks behavior. By comparing these models and techniques used previously to describe thermal stratification, the phenomenon could be better understood, exploited, and used to increase efficiency and thermal energy capacity in modern water tanks. From the existing models, we found the one-dimensional standard plug-flow and a multi node model to be appropriate for analyzing the processes of the heat up and cool-down in a water tank. These two models are based on energy balances. This work involved comparing the accuracy and computational effort needed to implement these models. To assess accuracy, we compared both types of existing models to experimental data (also collected in this work) which included a heat up process using an external heat pump. This external process included a layering process that has an eddy diffusivity at five times the rate of thermal diffusion. For this project, we implemented the models in MATLAB, the multi-paradigm numerical computing environment. We quantified model accuracy using the root mean squared error between modeled data and experimental data for six measured tank temperatures. Comparing the accuracy and the computational time taken to run the simulation provides a method to contrast the performance of each model and a way to rate it. The multi node model was run using from 6 to 96 spatial nodes; the plug flow model was run using 1 to 0.001 °C temperature bin sizes. Additionally, timesteps were varied from 4 to 236 s. The results quantify the tradeoff between accuracy and computational time, providing guidance for simulations to intelligently select the best model type and simulation parameters. This research can be used to validate the pre-existing models and possibly improve the modern water tank.

Perceptions of Kinesiophobia in Relation to Physical Activity and Exercise After Myocardial Infarction: A Qualitative Study

Objective Physical activity and exercise are central components in rehabilitation after a myocardial infarction. Kinesiophobia (fear of movement) is a well-known barrier for a good rehabilitation outcome in these patients; however, there is a lack of studies focusing on the patient perspective. The aim of this study was to explore patients’ perceptions of kinesiophobia in relation to physical activity and exercise 2 to 3 months after an acute myocardial infarction. Methods This qualitative study design used individual semi-structured interviews. Face-to-face interviews were conducted with 21 patients post-myocardial infarction who were screened for kinesiophobia (≥32 on the Tampa Scale for Kinesiophobia Heart). The interviews were transcribed and analyzed according to an inductive content analysis. Results An overarching theme was defined as “coping with fear of movement after a myocardial infarction—a dynamic process over time” comprising 2 subthemes and explaining how coping with kinesiophobia runs in parallel processes integrating the patient’s internal process and a contextual external process. The 2 processes are described in a total of 8 categories. The internal process was an iterative process governed by a combination of factors: ambivalence, hypervigilance, insecurity about progression, and avoidance behavior. The external process contains the categories of relatives’ anxiety, prerequisites for feeling safe, information, and the exercise-based cardiac rehabilitation program. Conclusion Coping with fear of movement after a myocardial infarction is a dynamic process that requires internal and external support. To further improve cardiac rehabilitation programs, person-centered strategies that support the process of each person—as well as new treatment strategies to reduce kinesiophobia—need to be elaborated. Impact Patients with a myocardial infarction were found to be ambivalent about how they expressed their fear of movement; therefore, it is crucial for physical therapists to acknowledge signs of fear by listening carefully to the patient’s full story in addition to using adequate self-reports and tests of physical fitness. These results will inform the design, development, and evaluation of new treatment strategies, with the overall aim of reducing kinesiophobia and increasing physical activity and participation in exercise-based cardiac rehabilitation.

ARCHIVE AND WARTIME AERIAL PHOTOGRAPHS AND PROCEDURES OF THEIR TREATMENT

The article presents with the use of archive aerial photographs. The first task was to search and identify drainage detail from archive aerial photographs. The second task is to create procedures for processing aerial reconnaissance images (from WWII) to identify sites with potential pyrotechnic load. Both of these tasks are connecting by the effort to determine the internal orientation parameters of the cameras for using and easier calculation of exterior parameters by image correlation. Complete automation process searching of fiducial mark (FM) identification was implemented. The coordinates of all FM are calculated automatically from archive aerial photographs. In addition, the edges of the photographs are automatically found and a program was created to minimize of the cropping of the archive aerial photographs. The next part of the paper describes the procedures of averaging the values of the relative position of FM and transforming archive aerial photographs to a uniform dimension from a set of images taken with the same camera. The second part of the paper describes the process of creating a historical ortophoto with the standard calculation of bundle adjustment performed by an external process in the background of the OrthoEngine module using the Celery library installed as a python service. Finding of external image orientation parameters through bundle adjustment calculation are parameters, in the first, defined in the local system and then transformed into the national geodetic system of the Czech Republic. This entire section is available and free to use for on the internet. The third part of the article describes the practical procedure of the interpretation of archive and wartime photographs with aim of identification of the drainage detail and the procedures leading to the interpretation, identification, location and calculation of the position of unexploded air ammunition.

New Indices for Evaluating Vibration Characteristics of Flexible-Joint Robots

Structural vibration is a significant consideration for robotic applications such as machining where the robot is subject to large dynamic loading. Aiming at providing an efficient means to evaluating the vibration characteristics of industrial robots for these applications, this work proposes two new indices to quantify the elastic displacement of the tool mounted on the robot caused by the vibrations induced by external process loading for flexible-joint robots. For this purpose, a structural dynamic model is first developed to derive the frequency responses of the tool displacement. Then, the displacement-force and displacement-torque frequency response ratios are defined, which represent the mapping from the amplitudes of an external harmonic force and torque to the amplitude of tool displacement respectively. The upper bounds of the two ratios are used as evaluation indices for the vibration characteristics of the robot, which represent the worst situation of the tool displacement due to harmonic excitation with amplitude of unit force and unit torque respectively. With these indices, an efficient method is provided to predict whether the tool misalignment caused by periodic loading is acceptable for process quality requirement. Numerical simulation demonstrates the effectiveness of the proposed method for a robotic riveting system being developed for aerospace assembly.
