Background and Objectives： Total laryngectomy is often required for advanced cases. But this operation induced the many inconvenience of basic daily life. Early diagnosis of laryngeal cancer is very important to prevent from this disastrous condition. In this point of view, mass screening test for early detection of laryngeal cancer is necessary. Screening test using voice has many advantages such as simple, less interventional. Voice collection by Automatic Response System(ARS) is comfortable and easy to got acoustic sample. Thus author tried to got the acoustic parameters which can differentiate normal, benign. and malignant laryngeal diseases and also checked the availability of parameters on neural network system. Materials and Methods: Author has evaluated the voice from 17 laryngeal cancer patients and 45 benign laryngeal disease patients who visited at Department of Otolaryngology, Pusan National University Hospital from May 1998 to April 2001, and 15 normal control. Author chose the sir Parameters (Jitt. vFo, Shim, vAm, NHR, SPI) that was thought to be related with voice collected by ARS among thirty-three parameters analysed by a Multi-Dimensional Voice Program (MDVP). Two-step neural network was used for the availability of six parameters. Results: The detection rate of normal voice by ARS voice analysis is 78.5% and detection rate of abnormal voice was 97.1 o/o. Among abnormal voice, the detection rate of benign laryngeal diseases and laryngeal cancers were 82.4 o/o, 70.6% respectively. Conclusion: Author concluded that six parameters and Matlab based neural network software may be effective in development of acoustic screening system for laryngeal cancer and further study should be necessary for development of new acoustic parameters.

Purpose: This study was to examine the effect of a taping therapy on pain relief and the improvement of daily living for elderly having degenerative knee arthritis. Method: This study was conducted with a non-equivalent control-group pre-test and post-test design. Data were collected conveniently with 63 elderly who had having(a) pain due to degenerative knee arthritis, and (b) inconvenience in daily life(30 for an experimental group and 33 for a control group). The subjects were recruited from the elderly, participating in welfare programs held in a welfare organization and day-care facilities. The experimental group received an intervention of taping therapy offered twice a week, for 4 weeks. The data collection from the experimental group was done from the beginning of the therapy throughout two weeks later after the end of the therapy. Results: For the experimental group, pain scores came to more decreased significantly, as the periods in which taping therapy was conducted were getting longer. Physical function scores became also more decreased at significantly level, as taping therapy was more conducted. However, compared to the control group, the score change for the experimental was not significantly showed in physical function after the therapy ended. That is, there was no longer-lasting effect on physical function improvement. Conclusion: This study found that this therapy could be a useful self-management method that the elderly with degenerative knee arthritis can use easily at home. Because of insignificant result in longer-lasting effect, this taping therapy would be applied properly with the interval of 2~3days.

In order to develop "textile electrode - sensing clothing" which is a sort of smart clothing to measure electric activities of heart, we propose possible ways to develop textile electrode and design of sensing clothing, ultimately aiming to develop "ECG sensing clothing for lifestyle monitoring". Conventional sensors for measuring typical electric activities of heart keep certain distance between measuring electrodes to measure signals for electric activities of heart, but these sensors often cause inappropriate factors (e.g. motional artifacts, inconvenience of use, etc) for monitoring natural cardiac activities in our daily life. In addition, most of textile electrodes have made it difficult to collect data due to high impedance and unstable contact between skin and electrodes. To overcome these questions, we minimized distance between electrodes and skin to maximize convenience of use. And in order to complement contact between skin electrodes, we modified textile electrode's form and developed ways to design clothing. As a result, we could find out clinical significance by investigating possible associations of clinical electrocardiogram (ECG) with variation of distance between electrodes, and could also demonstrate clinically significant associations between textile electrode developed herein and clothing.

As household energy consumption has increased, serious environmental problems, such as resource depletion and global warming, are becoming global issues. It is essential to conduct the energy use of residents living in apartments in order to come up with alternative solutions for energy savings. Therefore, this study examined the energy use awareness of apartment residents and their energy use behavior by various types of awareness. To understand their energy use behavior according to the awareness of the subjects, the energy awareness dimension was created with five factors and they were subject to a cluster analysis; then, the subjects were categorized into three groups. Finally, the difference of energy use behavior was examined by groups of energy awareness. G1 represents the group that is indifferent to energy savings and believes that convenience is an important factor. Also, with respect to energy use behavior, this group tends to pursue convenience. G2 is the group that is conscious of energy use costs thereby enduring some inconvenience, and shows savings behavior in daily life and household affairs. Although, G3 is very aware of the significance for the necessity of energy saving, their energy saving behavior is relatively negative. Regarding these different characteristics of each resident group in their energy saving awareness and behaviors, diverse methods and promotion in energy education are required. Furthermore, an effective energy policy should be established based on the understanding of energy consumption.

This study was conducted to identify the using self-nail products for the purpose of developing indicators to respond to changes in nail industry due to the evolution of consumption patterns caused by the spread of self-nail culture. The final analysis of 293 survey was conducted on female adults living in South Gyeongsang Province from September 1, 2018 to October 30, 2018. The study found that women in their 20s were more interested in nail care than in most cases. The main route of obtaining nail-related product information was the higher the use of SNS as the age was younger(${\chi}^2=185.048$, p<.001). According to a survey of 165 people who have experience with self-nail products, 53.3 percent of 'paste stickers' were the most common, followed by 39.4 percent of 'paste nail tips' and 7.3 percent of 'home care products'. Looking at the disadvantages of self-nail products, between groups under their 50s and over 50s group saw a significant difference(${\chi}^2=27.032$, p=.008). For those in their 50s or younger, 'the inconvenience of daily life' was considered a disadvantage. On the other hand, people in their 50s and older considered 'short duration' as a disadvantage. The lower the age, the higher the willingness to use continuously(${\chi}^2=14.308$, p=.006).We found that there were differences in preference for self-nail products according to age. It was noticed that there were differences in satisfaction and persistence. This suggests the need for more specific follow-up studies on the use of self-nail products by age group. Therefore, this research aims to present basic data for the development of direction and custom program for the professional nail industry to advance, thus providing basic data to help the development of nail industry in South Gyeongsang Province.
