The purpose of the present study was to explore the radiological and acoustic characteristics of "Arae-a" (/${\cdot}$/) articulation in two male Jeju language speakers, focusing on selected measures in radiological images derived from computed tomography scans, as well as the first and the second formant measures in selected vowels. An elderly male speaker (a 78-year-old) and a young male speaker (a 34-year-old) participated in the study. During the production of four selected vowels, the shape of the vocal tract was identified, and selected measures were obtained from the elderly participant's computed tomography (CT) scans. For acoustic analysis, the participants were given a list of near-minimal pairs consisting of 112 words and asked to read them aloud. The results indicated that the "Arae-a" (/${\cdot}$/) articulation of the elderly speaker showed unique acoustic and radiological characteristics compared to other similar vowels, thus presenting substantial consistency with the descriptions of the "Hunminjeongeum Haeryebon." In contrast, the F1 and F2 measures of the young male's /${\cdot}$/ articulation were not distinguished from those of /ㅗ/. Current results, in part, support the scientific principles underlying the invention of "Arae-a," which reflects the shape of the vocal tract during production, and the necessity for further research.

This study has been performed to review critical issues affecting continuous residence in profit(self-paid) assistant living facilities for the elderly in the United States. There are three factors influencing continuous residence of frail elderly in the facilities as long as they want without involuntary discharge : Financial ability, behavioral aspects, and facility management situation. Regarding financial ability, income, purchase of insurance policy, cashable assets, willingfulness to pay, and health status were found to be crucial determinants of continuous residence. Overall, 40-50% of those aged 65+ are financially able to stay in the assistant facilities as long as they want, without involuntary discharge. As for behavioral aspects, extroversions, congeniality, culture & life style, conscientiousness, preference for person, and physiological habits were found to be crucial determinants of continuous residence. As for the management situation, it is essential that facilities reach nature level of self-governing rights of the older residents and good local images, and conflicts among the residents and managing parties be resolved on the agreeable standards of inspectors. finally in this study, it is proposed that in Korea, national pension authority offer a liability package for assistant residence, for the case of individual bankruptcy.

This study was conducted for the purpose of analyzing volunteer workers' perceptions of and attitudes toward the behavior problems of the elderly residents after caring for the residents voluntarily at low-income nursing homes. Eleven male and female volunteers ranging from age 19 to 52 were asked how they felt about the elderly residents' behavior problems and what kind of behavioral problems they had experienced after doing volunteer works in the three chosen facilities. In particular, they were expected to explain what emotional changes they experienced during their volunteer service. In this study, it was observed that most of the elderly subjects experienced three categories of behavior problems: habitual, repetitious and unreasonable activities caused by the elderly residents' life span backgrounds, unexpected and/or abrupt behaviors resulting from gradual cognitive impairments, and physiological, awkward activities caused from gradual senility. The volunteers tend to believe that the elderly residents are naturally expected to act positively, since they have been provided with well- planned, regular care services such as bathing, counseling, activity programs, and religious guidances. On the other hand, some respondents stated that their experiences at the nursing homes caused them to form negative images of the elderly; they feel that the elderly are not helpful for giving advices on critical decisions, guiding and encouraging their daily lives, and offering any positive influences toward their own lives. Rather, they find themselves getting too much stressed as a result of their intimate contacts with demented or senile residents. Overall, in this study, it is proposed that education for confronting sudden abrupt behavior problems should be intensified more for female volunteers, since they tend to be more susceptible to emotional harassment resulting from the problem behaviors. It is also proposed that young volunteers who have not been systematically trained for confronting aggressive behaviors need to be separately assigned their roles in order to minimize the potential of confronting unseemly situations resulting from male residents whose mental health has deteriorated. Furthermore, it is also suggested that the combination of leisure-related activities for healthy residents and stressful intimate services for the frail residents be systematically planned and implanted for the volunteer program so that the volunteers can lessen the chances of suddenly finding themselves confronted with extremely abrupt agitations.

The purpose of the study was to investigate brand images and fashion leaderships of women's wear manufacturers targeting middle-aged women or older women. Thus, this study was to be an exploratory study to investigate clothing behavior of elderly female consumers and search apprel niche-market for them. The questionnaire consists of questions on brand images, fashion leadership, and merchandise assortment. The subjects were to evaluate their brand images and rated on 5 point Likert-type scales of 29 adjectives. The fashion leadership of these brands was evaluated by the degree of fashion trends adopted on 7 aspects including fashion images, silhouettes, fabrics, colors, design details, accessories, and item-coordinations. For the survey, both interview and the subjects were 66 manufacturers which have national brands or designer brands. Among 44 respondents, 30 respondents were designers and the rest of them were merchandiser or shop managers. The SPSS PC+ package was used to calculate frequency, T-test, and cluster analysis. The results from survey of manufacturers targeting middle-aged women or older women are as follow: 1) The brand imges which they pursue are prestigious, practical, and elegance. 2) There were significant differences in brand images, and national brand manufacturers pursue stronger images in prestigious, chic, intelligent, competency, than designer brand manufacturers. 3) 40 brands were divided into two clusters. 36 brands were included in one cluster, and only 4 brand were belong to the other cluster. In this market, the image of feminity was grouped with the image of prestigious, chic, intelligent, competency. 4) In product planning, the adption level of fashion trends in 7 aspects was generally at medium level, but fashion trends were more adopted in fabric, color, and item-coordination.

Purpose: With neurodegeneration, the signal intensity of the cerebrospinal fluid (CSF) in the brain increases. The objective of this study was to evaluate chemical exchange saturation transfer (CEST) signals with and without the contribution of CSF signals in elderly human brains using two different 3T magnetic resonance imaging (MRI) sequences Methods: Full CEST signals were acquired in ten subjects (Group I) with a three-dimensional (3D)-segmented gradient-echo echo-planar imaging (EPI) sequence and in ten other subjects (Group II) with a 3D gradient and spin-echo (GRASE) sequence using two different 3T MRI systems. The segmented tissue compartments of gray and white matter were used to mask the CSF signals in the full CEST images. Two sets of magnetization transfer ratio asymmetry (MTR_asym) maps were obtained for each offset frequency in each subject with and without masking the CSF signals (masked and unmasked conditions, respectively) and later compared using paired t-tests. Results: The region-of-interest (ROI)-based analyses showed that the MTR_asym values for both the 3D-segmented gradient-echo EPI and 3D GRASE sequences were altered under the masked condition compared with the unmasked condition at several ROIs and offset frequencies. Conclusions: Depending on the imaging sequence, the MTR_asym values can be overestimated for some areas of the elderly human brain when CSF signals are unmasked. Therefore, it is necessary to develop a method to minimize this overestimation in the case of elderly patients.

Purpose: This study is to investigate the muscle activity based on real-time visual feedback training methods by rehabilitative ultrasound image in elderly and correlation between Heckmatt scale grade, muscle tone and thickness. Design: Cross-sectional study: Pilot study Methods: 6 elderly participated in the study with 2 conditions. Under the condition of rehabilitation ultrasound imaging equipment, all subjects performed voluntary maximal muscle contraction of the quadriceps 3 times using visual feedback based on Rehabilitative Ultrasound Imaging 1.0 (RUSI 1.0). Under the condition of only ultrasound images, all subjects performed voluntary maximal muscle contraction of the quadriceps 3 times using ultrasound image-based visual feedback. The muscle thickness and tone of the quadriceps were measured and the grades were classified by Heckmatt scale and all variables were comparative analyzed. Results: Heckmatt scale grade showed a negative correlation with muscle thickness at relaxation (p<0.05), and a negative correlation with the difference value obtained by subtracting muscle thickness at relaxation from muscle thickness at contraction in ultrasound image condition (p<0.05). The muscle tone during relaxation showed a negative correlation with the muscle thickness during relaxation (p<0.05). Conclusion: In the case of voluntary maximum muscle contraction of the quadriceps muscle in the elderly, it can be seen that the muscle thickness is getting larger when the RUSI 1.0-based visual feedback is provided than with only ultrasound image provided. And the lower Heckmatt scale grade is, the thicker the muscle is, and the lower the muscle tone is.
