Abstract:
Maintaining dignity is the most important issue in old age which affects psychological health of the elderly. The present review of the literature aimed to investigate the concept of dignity and factors influencing it, in view of healthy and patient older adults, as well as healthcare givers.In the present study, the following websites were used: SID, Prequest, Cochran, Elsevier, Web of Science, PubMed, Magiran, Google scholar, and Iran medex. Initially, subject search, MESH, and keywords from 2000 to 2013 were used. Eventually, 24 articles with “dignity” as keyword remained and were studied.Concept of dignity varies, depending on understanding of the elderly. In view of a healthy older adult dignity meant inherent dignity, being active and respected, and interaction with others, and in view of older adults, dignity meant attention to pain, concerns about illness, and relationship with staff. Also, a healthy older adult considered dignity in having family relationships, care by the family, living in his own house, and the older adults regarded competence and courtesy of staff and acceptance of their weakness by the caregivers effective in maintaining dignity. However, health caregivers considered appropriate grounding including organizational factors necessary for maintaining human dignity.Given the views of the elderly about maintaining dignity and its dimensions, it is recommended that to maintain dignity of the elderly, nurses, caregivers and families should have necessary education.

Hossein Baghbany, Seyed Mohammad Ali Riyazy and Seyed Mostafa Bijani

Abstract:
In this paper, a multi-mode filter has been proposed and designed using operational trans-conductance amplifier (OTA) and grounded capacitors. Circuit of the proposed filter uses operational trans-conductance amplifier with multiple outputs (MO-OTA), operational trans-conductance amplifier with single output (OTA), two grounded capacitors and six switches. In this circuit, switches have been used for creating different modes including voltage mode, current mode, trans-conductance mode and trans-resistance mode. The proposed multi-mode circuit can simultaneously provide High-pass (HP), Band-pass (BP), Low-pass (LP), Band-rejection (BR) responses in the five output terminals. The parameters of the quality factor (Q) and natural frequency (?-o) of filter, can be adjusted electronically by Truns-conductance gain of OTA and values of separated grounded capacitors. Therefore, the quality factor (Q) without impact on the amount of natural frequency (?-o) can be adjusted. The sensitivity of the active and passive circuit parameters are low. Simulation with the H-Spice software confirmed the theory analysis results.

Mohammadreza Hosseinimasoum, Ghader Esfidani and Neda Hosseinimasoum

Abstract:
The results of researches confirm that the reported "net income" contain information which is related to company’s stock price valuation and economic performance of firms. But since there are income measurement process failure such as conflicts of interest between managers and shareholders it is needed to estimate and predict the future and taking advantages of several methods of accounting and other factors cause to increase the information content of profit and optimal use of this element in decision models will be threatened . One of the ways to deal with failure is disclosure and reporting of information to facilitate assess the “quality of earnings”. In this paper after presenting the components of profit, the impact of stable and predictable profit on the market value of common stock have been investigated using multivariate regression and time series models. With assessment of characteristics of earning quality using both earnings stability criterion and predictable income was clear that there is a direct relationship between earnings quality and stock market value. Whatever the quality of profit is high, stock market value will increase.
Keywords: Stable earnings, predictable earnings, the stock market value.
