In this essay the author gives a concise overview of the use of the word transpersonal in the life and writings of the Israeli Jungian analyst, Erich Neumann, who was born in Berlin Germany in 1905 and lived from 1934 until his untimely death, in 1960, in Tel Aviv. The paper provides readers with an overview of the correspondence that took place between Neumann and Jung from 1934-1959 and traces the way in which the word transpersonal was used in their mutual efforts to map out the terrain of the human psyche. What is made clear in the paper is that while Jung remained within the epistemological limits of empirical psychology in his theory of the collective unconscious, Neumann attempted to extend Jung’s epistemology into metaphysical territory, and in so doing he charted out a structural diagram of the psyche that extends beyond the archetypal field, to what he called the Self-field. The Self-field, Neumann argued, is a necessary postulate to include it in any complete inventory of depth-psychology that attempts to reach a new Weltanschauung. His attempts to extend Jung’s hypothesis of the Self into transpersonal territory began in his 1948 Eranos lecture in Ascona, Switzerland, “Mystical Man”. His calling from the Self led Neumann to venture forth a postulate of what he called a “New Ethic” for the field of depth-psychology as a whole. A distinction is made between the personal and archetypal shadow and evil, and the “Voice” Neumann refers to as part of the Transpersonal Self. The essay concludes saying it is tragic Neumann died at so young an age of 55, before he could formulate further how his Ethic related to his metaphysic. Neumann was the first Jungian analyst to present the world with a truly transpersonal theory of the Self that the author sees as essential reading for any transpersonal pedagogue who attempts to place Jungians in the history of the Integral movement.

The paper analyzes the technological preparation of production at the railcar enterprises in terms of developing technological processes and processing sets of technological documents. Factors affecting the quality of technological preparation of production for maintenance and repair of rolling stock are considered. In contrast to the previously performed works, where the assessment of the level of technological training was carried out by experts of a scientific organization, the initial data in the article were the results of a survey of specialists of technical departments of structural divisions of the car industry of the Sverdlovsk and South Ural Railways. Based on the method of expert qualimetry, the weight of factors that have the greatest impact on the quality of technological processes is estimated. As a result of the survey, a low level of automation of design processes was established, which consists mainly in the design of technological documentation. It is shown that the degree of depth of development and detail of technological processes is at the level of the route description

Abstract Maintenance plays an important role in reliability, availability, production quality, risk reduction, efficiency increasing, equipment security, etc. Therefore, maintenance strategies have a special position in industry. Simultaneously, effect of tractor power is considerable in agriculture; therefore, it is necessary to pay attention to the probability of failure, repair time and causes of malfunctioning. Many variables, including cost, depreciation, breakdowns, annual performance, etc., have major impact on tselection of a maintenance strategy. Therefore, these variables were determined with the help of experts. Subsequently, these were clustered into several main criteria groups on the basis of factor analysis using SPSS software. Obtained results were used in a hierarchical structure to suggest the most appropriate maintenance strategy based on pair-wise comparison. According to the regional conditions and available facilities, results showed that the proactive maintenance strategy proved to be the best suggested option from four maintain strategies, namely emergency maintenance, proactive maintenance, preventive maintenance, predictive maintenance.

Railway Rolling Stock

The value of the life cycle of rolling stock wheels is determined by the frequency of maintenance, in the process of which the turning is carried out to restore the profiles of the rolling surfaces, or the replacement of completely worn wheels. Traffic safety depends on the technical condition of the wheels of locomotives and wagons. Maintenance and repair of wheelsets accounts for about 30% of all costs of Ukrzaliznytsia's rolling stock repair units. Wheel repair technologies are based on the complete restoration of wheel profiles by turning, using which, their life cycle is reduced, and costs increase by 20% or more. The railways of Ukraine use an outdated, unreasonable, inefficient system of control over the formation of rolling surfaces in operation. Therefore, there is a need to create a scientifically sound approach to methods of extending the life cycle of the wheels of locomotives and wagons while ensuring the safety of railway rolling stock. According to the proposed scientific approach, the wheel profile is restored to optimal parameters, which provides an extended life cycle of wheelsets. As a result of the developed scientific approach the life cycle of wheel pairs will increase by 15… 25% and the expenses of the railway for their repair will considerably decrease.

Effectiveness Assessment

Based on the example of 6Dg type diesel locomotives, the paper presents a new maintenance strategy concerning periodical checks at the P1 maintenance level. Currently, such locomotives are sent off to service points every 102 hours of operation or every 14 days for a P1 level check. Studies demonstrate that the average distance to be covered by a locomotive to arrive at a service point is in excess of 60.0 km, and the quantity of fuel consumed is more than 88 litres. It is costly and time consuming to have locomotives out of service and considerable resources of the railway carrier are engaged which could be made use of in the transport process. The aim of the newly developed strategy of P1 checks is to eliminate the need for locomotives to exit their routes to reach rolling stock maintenance points. The control/diagnostic and maintenance activities specified in the Maintenance System Documentation will be performed by so-called mobile maintenance points. The development of the new strategy required: identification of the current condition of the maintenance system, development of the concept of a new strategy of P1 maintenance checks, conduct of studies and operational analyses for SM42 series locomotives, performance of a durability, reliability analysis, assessment of safety together with an analysis of the risks involved in the proposed changes. In order to review and assess the efficiency of the new strategy, an observed operation of selected locomotives was conducted together with a railway carrier. During the study, the maintenance activities and processes were monitored and the costs of P1 checks were recorded. The analysis of efficiency of the new strategy of performing P1 checks without the need for a locomotive to exit its route to reach a rolling stock maintenance point demonstrated that depending on the distance covered by the locomotive to reach a maintenance point, the unit costs of a P1 level check are lower by up to 67.1% compared with the currently applied method.

Planning Strategies

The efficiency of commercial automobiles and wheeled military vehicles mainly depends on the choice of maintenance (M) and current repair (CR) concept. In the paper the difficulties of adapting the (M) and (CR) planning strategies to the structural characteristics of modern transport facilities are pointed out. The advantages of using the (M) and (CR) random strategy for transport facilities based on the stochastic nature of failures and malfunctions are substantiated. Considering the failures and malfunctions as random values and identifying the patterns of their distribution based on γ percentage resources, it is proposed to develop a list of regulated maintenance and repair work, periodicity and labor intensity based on a random strategy, which will increase the efficiency of preserving the technical resource of the rolling stock throughout the entire life cycle of the vehicle.
