In this paper, we proposed a method of a hearing aid suitable for the sensorineural hearing impaired. Generally as the sensorineural hearing impaired have narrow audible ranges between threshold and discomfortable level, the speech spectrum may easily go beyond their audible range. Therefore speech spectrum must be optimally amplified and compressed into the impaired's audible range. The level and frequency of input speech signal are varied continuously. So we have to make compensation input signal for frequency-gain loss of the impaired, specially in the frequency band which includes much information. The input sigaal is divided into short time block and spectrum within the block is calculated. The frequency-gain characteristic is determined using the calculated spectrum. The number of frequency band and the target gain which will be added input signal are estimated. The input signal within the block is processed by a single digital filter with the calculated frequency-gain characteristics. From the results of monosyllabic speech tests to evaluate the performance of the proposed algorithm, the scores of test were improved.

The impaired person and the elderly who has hearing loss have been continuously increased and these people's desire for participating society as a producer has been increased also. So they strongly request the aid device which can compensate their handicap. The healing aid telephone is one of the basic aid devices that helps the hearing impaired to communicate with other people and to acquire useful information. We design the new model of the hearing aid telephone and test it's efficiency in three fields - electrical, speech perception, user test. From the result of the test we certify that the new model is better for the hearing impaired to understand the meaning of telephone speech than the old general models. We expect that the advanced healing aid telephone can be developed by the research about speech perception characteristics of the hearing impaired in engineering and clinical side.

This study sought to provide basic for the establishment of desirable sense of ethics values by analyzing the consciousness of biomedical ethics of freshmen nursing students. The subjects of the study were 420 freshmen nursing students. The period of data collection was from April 1 to 6, 2012 and collected data were analyzed on SPSS/PC 19.0 program. The results is followed; First, the mean score of the consciousness of biomedical ethics was $2.39{\pm}0.25$. While the mostly high ranked category of biomedical ethics was the right to life of newborn($2.76{\pm}0.39$), the category with the lowest score was the artificial abortion($2.13{\pm}0.39$). Second, with respect to the characteristics of participants there were statistically significant difference in total score according to age, religion, and participation in religious activity, experience of hearing for biomedical ethics, sources of information for biomedical ethics, ethical values for biomedical ethics, and in intention to attend biomedical ethics in subjects. As a result, an arbitration program that could promote either changeable or controllable ethical values must be considered with attention to the significant variables that can promote the consciousness of biomedical ethics of freshmen nursing students.
