Abstract
Along with increasingly development of CAD/CAM software and their application in various industries, minimizing of the machining time is found to be more important. In this paper, firstly the concerning subjects are discussed regarding classification of the optimization techniques. These are programming techniques, high speed machining techniques and feed rate optimization techniques. As a case study, an NC code was generated for machining of a plastic die by means of a dedicated software and the die was machined conventionally. Then the workpiece was machined using optimization techniques. Finally times taken for two approaches have been compared. The result shows machining time after optimization has been reduced considerably (64%).

Abstract
This paper is to develop a knowledge management (KM) model in some Iranian academic research centers (ARC) based on KM critical success factors. General KM critical success factors (CSF) were identified through literature review. Then the research procedure led to the identification of KM critical success factors in Iranian ARCs including 16 different factors. It was done through first stage survey by about 300 sample targets. Then, these 16 factors were surveyed separately again by experts through a Delphi panel. The experts suggested their practical solutions for exploiting the 16 factors in ARCs through a KM framework based on a KM cycle. This 2 years research has been done during 2006 to 2008.

Abstract
This paper demonstrates a preliminary investigation of geometry, function and its relation to DFX principles, namely DFM (Design for Manufacturing). This is the starting point for research on the development of an expert system that assesses design goals along DFX principles in a feature-based CAD environment. There is a need for a deeper level of understanding of the relationship between geometry and its effects on function, in order to correct and improve the product concept before large amounts of resources are invested in the product’s development.
This paper is a preliminary investigation into geometry and function involving DFM as part of an early stage of research into geometric effects on function and DFX through the use of CAD/CAE/CAM.In this paper, a concept is chosen to develop a parametric solid model that will be used to investigate a set of defined function attributes using model variants, which are evaluated in terms of the defined function attributes and DFM. The investigation found that for the functions defined, geometric parameters had less of an effect than expected. This is mainly due to the fact that the defined function attributes under investigation were associated with material properties. This paper demonstrates a preliminary investigation at the early stage of research to develop a more detailed relationship structure between geometry and functional attributes and their relationship with DFX. The end goal is to develop an integrated methodology involving geometry, function and DFX principles through the use of CAD/CAE/CAM .

Abstract
This study aims to explore gender differences in occupational stress sources, coping strategies, and emotional well-being among academic staff in Saudi public universities. The leading theory of transactional stress and coping implies the impact of stress and coping strategies on the health and well-being of people. The study surveyed 475 academic staff, 340 females and 137 males employed in Saudi public universities. They were invited to participate in the study by responding to the questionnaire. The study's significant findings reveal distinct variations in occupational stress levels between male and female academic staff. Additionally, it highlights gender-based differences in coping strategies employed by academic staff. Furthermore, the study identifies a prevalent issue of suboptimal levels of emotional well-being among academic staff at public universities in Saudi Arabia. These findings underscore the importance of addressing gender-specific stressors and promoting strategies for enhancing emotional well-being within the academic environment. The presented results consider relevant research, and the practical implications indicate that when Saudi-based universities implement policies and support systems for their staff members, they should consider the gender-based differences emphasized in this study. This could involve providing targeted support programs and policies to address the specific stressors that male and female academics face. Also, encouraging open communication, promoting work-life balance, and fostering a culture of well-being can contribute to creating a more inclusive and supportive academic environment for all faculty members.
