This paper proposes the use of a design structure matrix/work transformation matrix (DSM/WTM)-based methodology in academic settings to serve engineering educators as a facilitating tool for predetermining the difficulty and feasibility of design engineering projects they assign, given both the time constraints of the academic term and the expected skill level of the respective learners. By using a third-year engineering design project as a case study, engineering students actively participated in this comprehensive use of DSM methodologies. The engineering design process has been thoroughly analyzed to determine convergence characteristics based on the eigenvalues of the system followed by a sensitivity analysis on the originally determined DSM based on data provided by students in terms of task durations and number of iterations for each task. Finally, an investigation of the design process convergence due to unexpected events or random disturbances has been conducted. The obtained predictive model of the design process was compared to the actual dynamics of the project as experienced by the students and the effect of random disturbances at any point in the design process has thereby been evaluated.

The story of the Japanese system, held up as a model for economic prosperity and growth, underplays the role of non-standard labour in the narrative of `success'. Our analysis deconstructs the narrative of the Japanese economic miracle to shed light on this almost invisible pillar by tracing the historical development of non-standard employment among women. We find that this form of work constitutes a larger and faster growing share of total employment than heretofore realised, and that women account for most of the change. Rather than merely a residual dimension of Japanese employment practices, the evidence indicates that non-standard employment represents a key component of work transformation and underscores the salience of gender in the process of Japan's restructuring. We identify three institutional domains which help to explain this gendered pattern of labour market experiences in Japan: the labour market, the family, and the state. These institutional legacies set conditions for the development of the Japanese employment system which favours men as full-time wage earners and women as part-time wage workers and full-time care-givers.

The paper deals with the problem of the torque in the cantilever beam with annular cross section in the elasto-plastic domain, considering the material with elastic-linear hardening model. The cantilever beam is subjected to the alternating load of such frequency that the heat is generated in the beam. The quantity of the generated heat depends on the amplitude of the torque, frequency of the load and mechanical properties of the beam material. Equations which relate the value of the torque to the extent of the plastic region of the cross section and the shearing stresses of the beam in the elasto-plastic domain are given. Furthermore, equations for deformation work, transformation work, energy due to residual stresses and energy transformed into heat are presented. The article compares results concerning the temperature change at characteristic points along the beam, obtained via numerical analysis as well as experimentally.
