This study attempted to compare acoustic parameters, physiological observation and perceptual evaluation values obtained from the treatment and control groups in order to find out which of the self voice feedback therapies was better and which methods to train them were more effective. The experimental group carried out various self voice feedback therapies while the control group did only vocal hygiene. The acoustic measurement and voice manipulation for providing the patients visual, auditory feedback were done by a speech analysis software, Praat. The authors designed vocal hygiene, abdominal respiration and Praat self voice feedback therapies and applied them to 15 patients while applying only one vocal hygiene to 15 of the control group. For the purpose of examining the degree of their voice improvement after the treatment, pre- mid- and final evaluations were made for the two groups at the beginning, the 6th week and immediately after the 8th treatment session. Results of this study were as follows: The treatment group showed much improvement after receiving the voice treatment. In particular, acoustical and physiological indices from the optical endoscopy, pitch variation(Jitter), amplitude variation (Shimmer), maximum phonation time(MPT), and psychoacoustic evaluation showed statistically significant improvements over the control groups.

Self organizing map(SOM) is one of the unsupervised methods based on the competitive learning. Many clustering works have been performed using SOM. It has offered the data visualization according to its result. The visualized result has been used for decision process of descriptive data mining as exploratory data analysis. In this paper we propose improvement of SOM using stratified sampling of statistics. The stratification leads to improve the performance of SOM. To verify improvement of our study, we make comparative experiments using the data sets form UCI machine learning repository and simulation data.

The aim of this study was to examine the effects of remedial instruction on self-efficacy improvement in elementary school students with low self-efficacy, which may have been formed through negative experience with learning such as poor performance and poor grades. Nine 6th grade students with low self-efficacy were selected for the present study. A remedial class was set up and instruction was given once a week for 14 weeks. The purpose of the remedial class was to give the students a positive experience with English learning and have students reflect on their achievement. The contents and class activities were adjusted to the subjects' English abilities and also closely related to those of the regular classes so that students could have more confidence during regular English classes. The data were collected from a test of self-efficacy in English learning, achievement tests given before and after the experiment, achievement tests after each lesson, a general self-efficacy test, a basic questionnaire, interviews, journals, and students' self-evaluation. The results showed that the remedial instruction was very successful in providing students with a sense of achievement and improving students' self-efficacy in English learning. However, this study failed to find significant improvement in general self-efficacy tests and achievement tests given before and after the experiments. A longer period of remedial instruction may have been necessary to obtain more concrete results from the variety of data collected.

본 연구는 정서 행동장애(ADHD)아동을 대상으로 심리운동참여가 자아존중감과 우울감 및 과잉행동의 개선에 미치는 영향을 알아보는데 있다. 연구 결과 자아존중감, 우울감에서 집단간 주 효과의 유의한 차이가 나타나지 않았으나 과잉행동에서는 집단간 주 효과에 유의한 차이가 나타났다. 자아존중감, 우울감, 과잉행동에서 측정시점에 대한 주효과와 측정시점과 집단의 상호작용에 유의한 차이가 나타났다. 결론적으로 심리운동참여는 정서 행동장애(ADHD)아동의 자아존중감, 우울감, 과잉행동에 긍정적인 효과가 있는 것으로 나타났다. 심리운동이 아동의 움직임 발달만이 아니라 융합 차원에서 정서발달에 미치는 긍정적인 영향을 고려할 때, 정서 행동장애 아동은 심리운동에 지속적으로 참여할 필요가 있다고 사료된다.

This study measures patients' meal satisfaction according to the type of operation (self-operation and contract operation) and identifies improvement areas. A survey was conducted using 183 contract operation patients and 60 self-operation patients receiving general meals. The mean score for satisfaction for the whole sample was 3.42 (self-operation = 3.51; contract operation = 3.39), and self-operation satisfaction was significantly higher than contract operation satisfaction. Mean scores were 2.98 for food, 3.26 for menu composition, 3.57 for sanitation, 3.78 for distribution meal services, and 3.50 for menu information. Self-operation showed a higher satisfaction level than the contract operation in food and menu composition. The ccontract operation showed a higher level of satisfaction than self-operation in sanitation, distribution meal services, and menu information. In terms of feeling dissatisfaction with meal services, both groups showed the highest dissatisfaction with food and menus, and both groups agreed on food and menus that required the greatest improvement. Based on the results, contract operation managers should develop and apply menus considering their preferences. Dietitians of self-operation strengthen communication between meal service staff and patients by carrying out periodic and systematic service education on self-operation.

In this study, it is explored the effect of fashion therapy on depression, positive emotion, negative emotion, appearance interest, body satisfaction, self-esteem, and self-efficacy of female patients. Eight cancer patients and 12 general patients participated in the 4-week fashion therapy program. When comparing results before and after the fashion therapy, depression and negative emotions were significantly decreased while positive emotions and self-efficacy were significantly increased. There was no significant influence on appearance interest, body satisfaction, self-esteem, and self-efficacy. In group comparison, significant changes were observed in depression, positive emotion and negative emotion regardless of groups. However, cancer patients indicated a significant improvement in self-efficacy compared to general patients who did not whereas patients with a high level of depression showed a significant enhancement on body satisfaction compared to patients with a low level of depression. Also, patients with a low level of pain indicated a significant improvement on self-esteem and self-efficacy compared to patients with a high level of pain. Perceived effect and satisfaction of the fashion therapy were relatively high. Study results may positively contribute to building a knowledge and experimental base of fashion therapy that is widely applicable to diverse parties for the future.
