Today, with the proliferation of natural disasters on the one hand, and extended meaning of "commerce" On the other hand, the establishment of communication and crisis management in electronics, Development and crisis management in commerce SYSTEM design must be considered, especially in big cities is urban planning and management. On the other hand, the application of ICT as a tool tor coordinated and continuous service to the public, municipalities suitable for creating electronic has been provided; If the rate of formation of m-commerce services and decision-making to managers and consequently the rate of increase in critical condition. Accordingly, it must be said that the design of software SYSTEMs, including database SYSTEMs and expert SYSTEMs can help managers and decision makers, in a limited time, make more rational decisions. The purpose of this paper is to design a management information SYSTEM that is critical to commerce information SYSTEM designed according to the characteristics common to all crises. This SYSTEM is used for the design of UML. To reach a consensus for the design of practical examples, which are in fact the basis of information SYSTEM, the Business Function / Entity Type Analysis and design of a SYSTEM MATRIX, is used. Output in the form of three topics "recognition site", "transport and rescue victims" and "first aid" and a Once Upon a "start practicing".

The aim of the present study was the histological evaluation of Enamel MATRIX Derivative (EMD) effectiveness for regeneration of periodontal defects. EMD activates cementum synthesis, PDL and bone during the maturation stage of follicole. In this research, EMD was used in surgical defects of premolar teeth in four adult sheep. Muccoperiosteal flap was reflected in buccal site of teeth. The buccal bone plate was removed from mesial to distal in 4 mm depth. After eliminating the cementum by bur and its etching, EMD was applied on exposed dentine and flap was sutured. In opposite sites of those teeth (control sites) the same process was performed without etching. After 100 days, sheep were sacrificed and histological study through light microscopic was performed on black sections of operation sites. The results showed that in test sites, regeneration of cementum and bone was 62/5% and 42/5-50% respectively. But in control sites regeneration of cementum and bone was 37.5% and 32/5-42/5% respectively. Also the migration of junctional epithelium in control sites was 8-10% more than test sites. The important point is that in test sites, cementum was completely attached to undermining dentine. But, in control sites, the gap between cementum and dentine was visible. As a result, this study suggests that EMD promotes periodontal regeneration, and EMD application is a successful achievement in regenerative periodontal therapy.

In this paper, the fuzzy dual MATRIX SYSTEM as e AeX + e B = e C eX + eD in which e A; e B; e C; eD; eX are LR fuzzy matrices is studied. At  rst we solve 1-cut SYSTEM in order to  nd the core of LR fuzzy solution; then to obtain the spreads of the LR fuzzy solution, we discuss in several cases. The spreads are obtained by using multiplication, quasi norm and minimization problem with a special objective function. We prove some theorems and we suggest conditions in which the fuzzy dual MATRIX SYSTEM of e AeX + e B = e C eX + eD and the fuzzy MATRIX SYSTEM of ( e A ⊖ H e C)eX = (eD ⊖ H e B) have the same LR fuzzy solution and we discuss about the conditions where LR fuzzy dual MATRIX SYSTEM has crisp solution. Finally numerical examples are solved to illustrate the ability, accuracy and capability of the proposed method.

This study explores the motivational components within teacher rating SYSTEMs and their impact on professional growth motivation. Employing a SYSTEMatic review approach, it investigates texts pertaining to teacher rating SYSTEMs, motivation, and professional development literature. By examining various texts and research findings on teacher motivation, factors influencing teacher ratings based on general, specialized, and professional competencies, as well as experience, are identified. Drawing parallels with Herzberg's motivational theory, this study provides recommendations to bolster teacher motivation and job satisfaction through improvements in the rating SYSTEM.
