Mathematics is one of the core subjects in secondary education different modern concepts and methods are introduced in the syllabus of mathematics at secondary stage. The curriculum revision is being undertaken by the state department of education (SCERT) and the central department of education (NCERT) constantly and all the modern mathematics is incorporated at the secondary stage. The teacher education programs for preparing mathematics teachers are also strength and during the past to ducats whenever the curriculum is changes different researching programs such as refresher courses, seminars, workshops etc., are conducted to make true teaching of mathematics more effective in secondary schools. Hence in this paper it is proposed to undertake teacher wise and student wise analysis for this study keeping in view of certain variables like sex, locality, qualification, experience etc., and develop a tool to measure teaching effectiveness of mathematics teachers and also to understand the type of relationship between the teaching effectiveness and its relation to student achievement. The collected is analyzed by descriptive and inferential statistics.

This paper deals with the 3-co mponent identical system under the influence of hu man errors and Co mmon Cause Shock (CCS) failures. The M L estimates of system availability and frequency of failures were developed in the case of series and parallel systems. Also we developed empirical evidence to establish the valid ity of the proposed estimates by simu lation study. have complementary exponential distributions. Dhillon[5] discussed the role o f CCS failures and hu man errors in estimating reliability of a system. Sagar et al[8] developed the reliability and availability measures in the presence of CCS failures and human errors. He considered three component identical system.This paper presents, Maximu m likelihood estimat ion approach to assess the performance of the redundant systems. In this connection, we considered three co mponent identical system which is affected by human erro rs and Co mmon cause shock failures. The M L estimates are proposed for reliability indices such as availability function, frequency of failure function in the case of series and parallel systems. Also the proposed estimates are assessed based on simulated samples.

In this paper, we present an analytic hierarchy process based goal programming model for media mix planning in health care system. Today health care providers, like most business, are using advertising in order to attract customers (patients) to its products or services. Media selection involves the allocation of advertising budget among a variety of media options in such way as to maximize the number of potential customers reached. In this study we considered exercise products, personal care products, home medical devices and general clinical services of large health care system in Hyderabad. The problem was solved and results are discussed.
