Padronização e melhoria de processos produtivos em empresas de panificação: estudo de múltiplos casos

An important tool for organizational change is the standardization of procedures for developing standards so that companies have greater control, thus providing a broad view of their processes and needs. This paper presents and analyzes a model of standard processes developed by the bakeries in PROPAN (Support Programme Bakery), detailing each stage of deployment to evaluate both its benefits for companies and employees and its shortcomings, to make proposals for improvements. Five bakeries were selected for this multi-case study, whose methodology consists of qualitative research using semi-structured interviews, on-site observations and document analysis. The main positive points of the model are the possibility of standardized recipes and procedures, a large decrease in wasted raw material and a significant increase in worker productivity. The main challenges are the lack of employee and owner commitment to the project, the lack of materials needed for deployment and the resistance of employees to change.

Critical factors to be considered when planning the implementation of environmental improvements and energy saving

To identify the critical success factors in the adoption of energy efficiency actions in Brazilian hospitals and describe their behaviour are the objectives of this paper. In order to achieve these goals, a literature review was performed on green management and energy efficiency. This was the basis to define the questions of the interview script applied to two hospitals located in the state of Sao Paulo, Brazil. The interview script application was complemented by secondary data and direct observation. The results showed that: a) the studied hospitals are embracing environmental management actions more often and, whenever possible, energy efficiency actions are taken as well; and b) in the cases analysed top management support, commitment with the environment, green process design and employee empowerment were some of the most relevant critical success factors to the accomplishment of energy efficiency actions. These findings may be of interest to emerging countries, including BRICS (Brazil, Russia, India, China and South Africa).

Aggressive osseous commitment result by keratocyst odontogenic tumour: case report, radiographic and clinical standpoints

Keratocystic odontogenic tumour (KCOT) previously known as odontogenic keratocyst was recently classified as a benign lesion characterized by an infiltrating pattern, local aggressiveness with the propensity to recurrence. It is thought to arise from the dental lamina. Pain is usually not associated with KCOT until swelling occurs, and it commonly affects the posterior mandible. Multiple KCOT are associated with nevoid basal cell carcinoma syndrome. This study reports an aggressive case of KCOT with destruction of the osseous tissue of the mandible, accentuated face asymmetry, dysphagia and dysphonia. It was managed with a defined protocol which entailed diagnosis, treatment with enucleation along with peripheral ostectomy and rehabilitation. A long-term follow-up schedule was provided to the patient to observe the recurrence behaviour of this cyst. In postoperative phase, no complication was noticed regarding wound healing and recurrence.
