Soft Systems Methodology (SSM) was devised by Checkland (1981) and elaborated by Checkland & Scholes (1990) to provide a tool for investigating an unstructured problem situation. SSM is not a system design tool, but a tool for system requirements investigation. Unlike systems analysis tools, such as entity-relationship modelling or data-flow diagrams, which allow the designer to model how the s...

Based on a novel bare surface soil moisture (SSM) retrieval model developed from the synergistic use of the diurnal cycles of land surface temperature (LST) and net surface shortwave radiation (NSSR) (Leng et al. 2014. “Bare Surface Soil Moisture Retrieval from the Synergistic Use of Optical and Thermal Infrared Data”. International Journal of Remote Sensing 35: 988–1003.), this paper mainly in...

OBJECTIVE Is skin-sparing mastectomy (SSM) with conservation of the Nipple-Areola Complex (NAC) and immediate autologous reconstruction as safe in oncologic terms as SSM with resection of the NAC as modified radical mastectomy (MRM)? SUMMARY BACKGROUND DATA The originally described technique of SSM included the removal of gland, NAC, and biopsy scar. However, the risk of tumor involvement of ...

Aim: To review the oncological safety and aesthetic advantage of skin-sparing mastectomy (SSM) for invasive breast cancer (IBC) and ductal carcinoma in-situ (DCIS). Controversies including the impact of radiotherapy (RT) on immediate breast reconstruction (IBR), preservation of the nipple-areola complex (NAC) and the role of endoscopic mastectomy are also considered. Methods: Literature review ...

Figure 6: Strongly related (SSM based) functional sets and similarities between them, Case Study I. Nodes represent set of closely related methods; weight of the edge between two nodes represents the average value of SSM among the methods of the corresponding sets. Non trivial sets are represented by smaller circles and are merged with trivial sets (bigger circles) of the same color.. Figure 11...

Problem statement: In this research, it had been presented a novel Skew Scenario Model that has been developed and implemented for mobile ad hoc networks. There exist several mobility patterns that try to capture the behavior of the mobile devices under different circumstances, whereas in our work, the direction movement of the nodes is significantly specified horizontally, vertically and diago...

purpose : to report a patient with sphenoid sinus mucocele (ssm) case report : the patient is a 19-year-old man who was referred to khatam-al-anbia eye center as retrobulbar optic neuritis. brain and orbital ct scan and mri revealed ssm. the patient underwent endoscopic sinus surgery and visual acuity (va) improved from no light perception (nlp) to 2 meter counting fingers. conclusion : ssm may...

The effects of body size and feed intake on N digestibility, pancreas and Liver weight, and digestive enzyme activities in male broiler chicks were compared with those induced by dietary tannins. Four groups (SSM, ad lib., pair-fed and young) of sixteen birds each (2 weeks old) were used as experimental animals. They were fed on experimental diets for 4 weeks, except the young group which were ...
