  • The purpose of this study was to compare professional (Pro) and non-professional (Non-pro) voice users with voice disorders in self-reporting voice evaluation using Korean-Voice Handicap Index (K-VHI) and Korean-Voice Related Quality of Life (K-VRQOL). In addition, those were compared by voice quality and voice disorder type. 94 Pro and 106 Non-pro were asked to fill out the K-VHI and K-VRQOL, perceptually evaluated on GRBAS scales, and divided into three types of voice disorders (functional, organic and neurologic) by an experienced speech-language pathologist and an otolaryngologist. The results showed that the functional (F) and physical (P) scores of K-VHI in Pro group were significantly higher than those in Non-pro group. As the voice quality evaluated by G scale got worse, the scores of all aspects except emotional (E) of K-VHI and social-emotional (SE) of K-VRQOL were higher. All scores of K-VHI and K-VRQOL in neurologic voice disorders were significantly higher than those in functional and organic voice disorders. In conclusion, professional voice users are more sensitive to their functional and physical handicap resulted by their voice problems and that goes double for the patients with severe and neurologic voice disorders.

  • The purpose of this study was to identify functional impairment and psychological status and to analyze their relationships in patients with chronic arthritis. The sample was consisted of 75 arthritic patients who visited H hospital and S welfare center. Functional impairment was measured by ADL, pain, and the number of painful joint. Psychological status was measured by depression, self-efficacy, and quality of life. Data was analyzed by frequency, mean ${\pm} SD$, Pearson's correlation coefficient, and Stepwise multiple regression. The results of this study were as follows : 1. In functional Impairment, ADL was below average which means somewhat difficult, pain was above average, and the number of painful joint was 9.20. 2. In psychological status, scores of quality of life was 97.89, depression was 41.28, self-efficacy was 895.35. 3. Pain was negatively correlated to self-efficacy, ADL and quality of life, and positively correlated to depression. 4. Self efficacy and depression explained 45% of the variance in quality of life. Therefore, it is suggested that nursing intervention improving psychological status would be useful for patients with chronic arthritis. Especially, it is very important to implement nursing intervention focused on increasing self-efficacy and decreasing depression.

  • Purpose: The purpose of this study was to identify effects of a self-management program on symptom and functional status, health perception, and quality of life(QOL) of patients with CHF. Methods: Patients with CHF as defined through clinical judgment using the Framingham criteria and EF<50% were enrolled in the study (experimental: 21, control: 20). The symptom focused self-management program consisted of coping behaviors for symptoms including dyspnea, chest discomfort/pain, dizziness, ankle edema, and basic self-management including medications, diets, activity, lifestyle changes. Experimental group received an educational booklet after survey, and periodic telephone follow-up by a trained nurse. Data were collected the 3rd day after admission and at 1 month, 3 months, and 6 months after discharge using questionnaires. Results: Significant differences were found in the presence of symptoms, health perception, and QOL between groups during follow-up. Although no significant difference was found in functional status, the experimental group reported better functional status than the control group. Conclusion: By facilitating self-management of CHF using tailored interventions including education programs and telephone monitoring, it is expected that patients will be able to monitor their symptoms routinely, adhere to therapeutic regimen, and have a better QOL.

  • Rice ageing describes the changes in physical and chemical properties of rice grains during storage that alter the eating quality of rice. The prevention of deterioration in palatability of rice during storage is important for stable supply. In this study, We conducted to select the variety with superior palatability after storage at room temperature. 'Yeonghojinmi' had much higher head rice ratio of milled rice than that of 'Ilmi', 'Junam'and 'Hwayeong'at similar moisture content of approximately 15%. Grossiness and stickiness were higher in 'Yeonghojinmi' than that of the others. Meanwhile, yellowness(b value) of cooked rice was lower in 'Yeonghojinmi' than that of the others. Of the four varieties, Yeonghojinmi was maintained good eating quality after storage in room temperature, which also contributed to differences in palatability, such as protein content, glossiness, stickiness and color of cooked rice.

  • This study intends to present basic materials for the development and production of functional dumpling skins by making rice flour-added functional dumpling skins and analyzing the nature of its quality. The moisture content of dumpling skins increased with high addition of rice flour. The color value of dumpling skins changed little with high addition of rice flour. The hardness of dumpling skins showed significant difference in all storage periods with the addition of rice flour. For the sensory properties of dumpling skins with the addition of rice flour, where 25% and 50% rice-flour were added, dumpling skins showed a high score in overall quality for O-day and 7-days of storage. In particular, the 50% rice-flour dumpling skin mixture indicated the highest score. For the correlation between textural and sensory properties according to the addition of rice flour, 0 day-stored dumpling skins showed a positive correlation between smoothness and moistness in the mouth feel and the overall quality (p<0.01) in the sensory properties. Wheat odor (r=0.68) and chewiness (r=0.65) also correlated positively with overall quality (p<0.05). Hardness in textural properties correlated positively with moistness (r=0.69) and the mouth feel (r=0.65) of dumpling skins (p<0.05). Hardness in textural properties correlated positively with adhesiveness (r=0.99) and chewiness (r=0.93, p<0.01). Dumpling skins stored for 7 days showed a positive correlation between hardness, chewiness, and moistness in the mouth feel and overall quality (p<0.05) in the sensory properties. Hardness in textural properties correlated positively with gumminess (r=0.65, p<0.05).
