Product to process lifecycle management in assembly automation systems
Presently, the automotive industry is facing enormous pressure due to global competition and ever
changing legislative, economic and customer demands. Product and process development in the
automotive manufacturing industry is a challenging task for many reasons. Current product life
cycle management (PLM) systems tend to be product-focussed. Though, information about
processes and resources are there but mostly linked to the product. Process is an important aspect,
especially in assembly automation systems that link products to their manufacturing resources. This
paper presents a process-centric approach to improve PLM systems in large-scale manufacturing
companies, especially in the powertrain sector of the automotive industry. The idea is to integrate
the information related to key engineering chains i.e. products, processes and resources based upon
PLM philosophy and shift the trend of product-focussed lifecycle management to process-focussed
lifecycle management, the outcome of which is the Product, Process and Resource Lifecycle
Management not PLM only

The prevalence of recurrent abdominal pain and some relative factors among children beginning primary school in Bushehr port
Recurrent abdominal pain (RAP) is a common problem in children and adolescence. The functional abdominal pain is the most common cause of RAP. The conceptual models of RAP are multivariate and acknowledge the contributions of a variety of biological, psychological, and social factors. Among the 6-7 year-old population of Bushehr port, 485 (50.1% male, 49.9%female) children starting primary school were randomly selected. Questionnaires were completed by direct interview during the National Program of Health Surveillance of Schoolchildren in 2000. According to Apley's criteria, 49 children had RAP (9.1% male and 11.2% female). Abdominal pain pattern such as frequency, duration, location, radiation, associated symptoms was relatively similar to other investigations. The signs of environmental reinforcement of pain behavior such as specific attention and medication at time of pain were commonly observed (32.6% and 71.4%, respectively). Prolonged duration of involvement (73.5%, more than one year) and frequent referral to physician (30.6%, at least three referral) were detected. Some psychosocial stress such as father unemployment and history of irritable bowel syndrome (IBS) in parents were significantly more frequent in RAP group (p values= 0.038 and 0.01, respectively). History of RAP in siblings and appendectomy, peptic disease and migraine were mildly more frequent in RAP group. Separation of one of the parents, change of address, parent education and mother employment, sibling number and order and weight and height had not significant differences between two groups. Among 22 patients, giardia cyst was detected in the stool of 4 patients (18.2 %). In conclusion, RAP is a common problem in Bushehr port and its pattern was relatively similar to other regions. The father unemployment and the history of IBS in parents, two psychosocial stresses, were associated with RAP
Urban development assessment in flood hazard areas using integrated HEC-RAS, SCS, and FAHP models:a case study of Pardisan Settlement, Qom
Alluvial fan surfaces present unique challenges for urban development due to their susceptibility to flooding and other environmental hazards. This study focuses on the Pardisan settlement in Qom, which houses over 200,000 residents and is particularly prone to flood risks due to its geographical characteristics. The primary aim of this research is to identify and manage areas within Pardisan that are optimal for safe and sustainable urban expansion. To address this goal, we utilized a comprehensive methodology that includes flood risk modeling with HEC-RAS 6, using the Soil Conservation Service (SCS) method for a hypothetical 100-year flood event. Additionally, we incorporated 13 development criteria, developed from expert consultations, to assess land suitability for urban development. These criteria were analyzed using the Analytic Hierarchy Process (AHP) combined with Fuzzy logic, facilitating a nuanced comparison of potential sites for expansion. Our findings reveal that, despite existing watershed management and road infrastructure adjustments, current settlement areas in Pardisan remain vulnerable to flooding. The research highlights deficiencies in current flood prevention measures and underscores the need for enhanced strategies and further studies. Flood modeling showed that major infrastructures, such as bridges in the eastern sector of the settlement, are likely to withstand a 100-year flood, whereas smaller railway bridges require ongoing monitoring to manage debris accumulation. Furthermore, the channel within Pardisan is inadequate for managing the water flow and sediment from such a flood event, and upstream dams do not sufficiently address the volume and sedimentation challenges posed by potential floods. The outcomes of the AHP-Fuzzy model identified the southeast section of Pardisan as the most suitable area for future urban development. This recommendation is based on a thorough evaluation of the specified criteria, pointing to significant potential for targeted, optimal urban expansion in this region
Pulmonary Hydatid Cyst and Successful Renal Transplantation
Hydatid cysts are endemic hooknoses in Iran. It may involve various organs of body.Liver is involved in 80% and lung in 10- 15%of cases. 25% of pulmonary hydatid cyst is bilateral.Before any transplantations eradication of infection is necessary.In a 26-year old man with renal failure referred for kidney transplantation. On initial preoperative evaluation of this patient hydatid cyst lesion was found in two lungs, left side operated,and right side left in place. Under treatment with albendazole kidney transplantation was performed. After two-year of follow-up, patient was in good condition and the size of right cyst did not increased
