S. A.) design increasing consciousness at the persons in population. Section 1, we discussed the definition of diabetes in children, type of diabetes in children, symptoms, complications of diabetes, methods of treatment in children, the measure glucose decrease in children, reasons for low blood glucose, signs and symptoms of low blood glucose, lower of blood glucose in children during sleep and diabetes prevention. Section 2, we project the result of questionnaire and write the statistical analysis for this subject and summaries on the results and illustration by figure.

Recurrence relations connecting the various probabilities introduced are found. Some measures of effectiveness are deduced and some special cases are also obtained. Keywords: queueing system: M X /H k /1/N, hyperexponential DESCRIPTION OF THE SYSTEM Morse [4] discussed the steady-state queueing system in which the service channel consists of two branches, the units arrive singly and the capacity of the waiting space is infinite. Gupta and Goyal [1] studied a similar system by using the generating functions with k branches in the service channel, the units arrive singly and the capacity of the waiting space is finite. Habib [3] and Gupta and Goyal [2] treated the system M X /Hk/1. White et al. [6] solved the system: M/H2 /2/2 numerically. All the previous studies are without balking and reneging. In the present system, it is assumed that the units arrive at the system in batches of random size X, i. e., at each moment of arrival, there is a probability Cj = Pr (X= j) that j units arrive simultaneously, and the interarrival times of batches follow a negative exponential distribution with time independent parameter . Let Cj t, (j = 1, 2,..., N), be the first order probability that a batches of j units comes in time t. The service channel is busy if a unit is present in any one of the k branches and in this case the arrival units form a queue and the capacity of the system is N. The unit at the head of the queue requires service in the r th branch with probability *. The service time distribution in the r th branch is * The variation of the subscripts i,j,r,s is from 1 to k, unless otherwise explicitly mentioned.

These processes occur often in practical applications. And the difficulty in obtaining friendly results for is a great obstacle to its application in practical cases modelling. It is exemplified the application to the queue particular case. The work presented in (5) is resumed but now the emphasis is put in the determination of a pfaffian solution that must be considered in this example.

The change in grade of RD, or succession, has led to ecological degradation and seriously hindered socioeconomic development. RD succession is influenced by soil and vegetation. Taking central Hunan regions as a study area and using SPSS17.0 statistical software, we investigated the correlation between RD grades, plant diversity index and soil factors. Results showed that RD grades showed a significant positive correlation with soil organic matter (OM) and cation exchange capacity (CEC). The plant diversity index was positively correlated with the soil fertility index and showed a significant positive correlation with OM and available elements. Further analysis on the available elements showed that total plant diversity indices including Shannon-Wiener index H', Pielou index E and Simpson P had significant positive correlations with available magnesium (AMg). Total plant diversity indices E and P had significant positive correlations with available calcium (ACa). These conditions might have closely reflected the particular microhabitat types of RD regions. The correlation between RD grades, vegetation and soil factors suggested that the relationship of the three was co-evolutionary. To enhance RD control and treatment effectiveness, increasing the content of the ACa and AMg may be more impactful than increasing the content of OM in central Hunan.

In particular, the convex sets separation. In this work the Hahn-Banach theorem is presented, with great generality, together with an important separation theorem, its consequence. Then are followed the necessary mathematical steps towards the minimax theorem, an important result in the applications of Game Theory to economics, finance and management.

Their disabilities and their strengths are often overlooked. Teachers may only focus on a student's weakness and fail to see high intelligence, or the giftedness may mask the disability and cause the child to appear average. Even when they are correctly identified, gifted and learning disabled students' social, emotional, and intellectual needs are often overlooked in the effort to remediate their disability. These students must be correctly identified as being gifted and having a learning disability in order for their needs to be adequately met. Effective programming for gifted and learning disabled students also includes social and emotional support, as well as interventions which focus on strengths, rather than weaknesses. These students will meet their potential only when their needs are appropriately met. REVIEW OF LITERATURE This paper reviewed literature which addressed the characteristics and needs of students who are gifted and learning disabled. A discussion of the academic needs as well as the social and emotional needs of these students was included. Gifted and learning disabled students' social, emotional and intellectual needs are often overlooked in the effort to remediate their disability. Identification of these students and the challenges associated with it were examined. Often, a student's giftedness, or their learning disability, or both, remain undiagnosed, and these students do not receive appropriate interventions. Even when they are identified, it is common for the learning disability to be the only need that is acknowledged. These students must be correctly identified, both for their giftedness and for their learning disability, in order for their unique needs to be adequately met. Effective programming for gifted and learning disabled students includes social and emotional support, and interventions which focus on strengths rather than weaknesses. Only when their needs are appropriately met will these students meet their potential.
