The purpose of our study was to provide effective speech evaluation items examining the variables of speech that successfully predict the speech intelligibility in CP children. The subjects were 55 children with spastic type cerebral palsy. As for the speech evaluation, we performed a speech subsystem evaluation and a speech intelligibility test. The results of the study are as follows. The evaluation task for the speech subsystems consisted of 48 task items within an observational evaluation stage and three levels of severity. The levels showed correlations with gross motor functions, fine motor functions, and age. Second, the evaluation items for the speech subsystems were rearranged into seven factors. Third, 34 out of 48 task items that positively correlated with the syllable intelligibility rating were as follows. There were four items in the observational evaluation stage. Among the nonverbal articulatory function evaluation items, there were 11 items in level one. There were 12 items in level two. In level three there were eight items. Fourth, there were 23 items among the 48 evaluation tasks that correlated with the sentence intelligibility rating. There was one item in the observational evaluation stage which was in the articulatory structure evaluation task. In level one there were six items. In level two, there were eight items. In level three, there was a total number of eight items. Fifth, there was a total number of 14 items that influenced the syllable intelligibility rating. Sixth, there was a total number of 13 items that influenced the syllable intelligibility rating. According to the results above, the variables that influenced the speech intelligibility of CP children among the articulatory function tasks were in the respiratory function task, phonatory function task, and lip and chin related tasks. We did not find any correlation for the tongue function. The results of our study could be applied to speech evaluation, setting therapy goals, and evaluating the degree of progression in children with CP. We only studied children with the spastic type of cerebral palsy, and there were a small number of severe degree CP children compared to those with a moderate degree of CP. Therefore, when evaluating children with other degrees of severity, we may have to take their characteristics more into account. Further study on speech evaluation variables in relation to the severity of the speech intelligibility and different types of cerebral palsy may be necessary.

Background: Quality ratings could provide vital information to help people in choosing a nursing home. Purpose: This study investigated factors aligned with quality ratings of nursing homes. Methods: We employed a cross-sectional descriptive design to assess publicly available data on 1,354 nursing homes with 30 or more beds in the Republic of Korea. After excluding 289 nursing homes with no reported quality-evaluation ratings, we analyzed the 2015 data of 1,065 nursing homes. To prevent multicollinearity among independent variables, we carefully selected the final set of variables based on clinical and theoretical meaningfulness to direct nursing care. Quality, the ordinal outcome, was scored from 1 to 5 with a higher score indicating higher quality of the organization. We constructed a multivariate ordered logistic regression model. Results: Higher quality ratings of nursing homes was significantly related to the number of unoccupied beds (OR=0.99, p=.024), registered nurses (RNs) (OR=1.30, p=.003), qualified care workers (OR=1.03, p=.011), cognitive-improvement programs (OR=1.05, p=.024), and other programs for residents' activities (OR=1.09, p<.001). Conclusion: The number of RNs had the strongest influence on the publicly reported quality rating, while the rating of qualified care workers demonstrated little effect and that of nursing assistants had no effect. The number of RNs could be used as a crucial indicator for high-quality homes; more resident-engaging programs also demonstrated better quality of nursing home care.

To assess premenstrual changes in adolescents, a self rating retrospective premenstrual assessment from(PAF) and a prospective daily rating form(DRF) were administered to 230 high school students who reported premenstrual changes. The results were as follows 1) According to typological categories of retrospective premenstrual assessment form, the most commonly reported changes in mood and behavior were major depressive syndrome(40.0%), impulsive syndrome(20.9%). Especially among the subtype of depressive syndrome, hostility feature and withdrawal feature were most frequent. The most commonly reported changes in physical condition were general discomfort(73.5%), fatigue(33.9%). 50.9% of all subjects reported impaired social function. 2) 41.2% of the subjects who met the criteria for typological categories of retrospective premenstrual assessment form were confirmed by prospective daily rating form. 3) According to different criteria of percent change method of assessing symptom change, 38.7% of all subjects had at least one mild premenstrual change and 23.5% had at least one moderate premenstrual change. 4) Using prospective daily rating form, overall psychological changes were confirmed more frequently than physical changes. Of the mild premenstrual changes, 'low energy, tired & weak', 'less or impaired work' were most common changes. Of the moderate premenstrual changes, the most common change was 'low energy, tired & weak'. 5) As attitude toward menstruation, 44.9% of the subjects with confirmed premenstrual changes had more negative attitude(disgusted) toward menstruation. 6) The subjects with confirmed mild or moderate premenstrual changes had only dysphoric mood changes or both physical and dysphoric mood changes, but did not have only physical changes. These results suggest that retrospective reports of premenstrual changes were partially confirmed by daily prospective ratings. A substantial number of adolescents appeared to experience premenstrual changes, and the most common confimed premenstrual change of mild or moderate severity was 'low energy, tired and weak'.

The purposes of this study were; 1) to gather data relevant to demographic features. major main management practices, and the level of impairment of the activities of daily living (ADL) of patients with back pain, 2) to test the sensitivity of the Korean Pain Rating Scale and the Graphic Rating Scales, and 3) to identify indirect indicators of back pain by analysing pain related-behaviors. The level of pain was measured by Korean Pain Rating Scale(KPRS) and Graphic Rating Scales(GRS) developed by the reserchers. The GRS consists of two dimensions; the pain intensity (sensory) and unpleasantness (affective) measures. Of the 1,650 diagnosed back pain patients, from January 4 through June 30, 1987 by visiting outpatients' clinics of orthopedic and neurosurgical departments at 11 university hospitals in different districts of Korea, 330 men and women patients were self-selected by responding to the mailed questionnaires. The results were summarised as follows: Male exceeded female patients in number and onset of back pain were more prevalent in the age groups of 20s and the 30s. The average duration of suffering from the pain were 11 months, sixty three (19.1%) of the subjects retired from their jobs, one third(36.7%) have teen hospitalized for the treatment of back pain. In two thirds(64.8%) of the cases pain was characterized as lower back pain. The average sleep hour was 6.8 hours per 24 hours and the average rest hour during the day was 3.3 hours. The mean percentage of pain measured by GRS was higher than that of KPRS. The level of sensory intensity as well as the affective level of pain measured by KPRS and GRS were not highly correlated (sensory intensity r=0.4986, affective r=0.5029) which indicated low discriminative power. On the other hand, intercorrelation between sensory and affective dimension measured by KPRS and GRS showed moderate interrelation(r=0.7247; r=0.7899). One-third(32.5%) of the subjects complied with the hospital prescribed treatment while the other one-third(31.5%) depended on self-remedy and traditional practices, and the last one-third did not imply any pain management practices. The following 6 pain-related behaviors such as length of hospitalization, rest hour during day hours, varieties of pain management practice implied, number of pain sites, need for ADL and discomfort accompanied by ADL revealed to be important indicators of back pain. An investigation of sociodemographic features of patients with back pain in a larger context, i.e. with bigger number of respondents is recommended. Tests for construct validity of KPRS, i.e. factor analysis is further recommended.
