This study aims to compare the acoustic characteristics of vowel phonation in children with spastic and dyskinetic cerebral palsy (CP). Thirty-four children aged 4-12 years with CP participated in the study (spastic 26, dyskinetic 8). Voice samples for the acoustic analysis were extracted from a sustained vowel /a/. All acoustic measures were made using Praat. Group differences were compared by an independent t-test or Welch-Aspin test, if the equivalence assumption was not met. The results of this study are as follow. First, maximum phonation time(MPT) was significantly shorter for the dyskinetic CP than for the spastic CP. Second, shimmer percent was significantly increased in the dyskinetic CP than in the spastic CP. Lastly, there were no significant group differences in both the first formant and the second formant. These findings indicate that the dyskinetic CP has a poorer respiratory capacity and poorer laryngeal function than the spastic CP. On the other hand, both groups have a comparable ability to articulate the vowel /a/. The results of the present study help speech language pathologists identify the speech motor control ability of children with two types of CP (spastic and dyskinetic) and help to make an intervention plan associated with a specific type of CP.

This study examined whether there are differences in the empathic ability and emotional intelligence by college students' counseling course-taking experience and major. The research subjects were 313 college students, and an independent sample t-test, one-way ANOVA, and Duncan post-hoc test were conducted for hypothesis testing. A difference in empathic ability was observed according to the students' sex, major, and counseling course-taking experience. A difference in emotional intelligence according to their sex and counseling course-taking experience was noted. Empathic ability was higher in females than in males, higher in the school of social sciences than in the school of science and technology, and higher in those who had counseling education than in those who did not. Emotional intelligence was higher in women than in men, and higher in students who had counseling education than in those who did not. Consequently, the effectiveness of counseling education was confirmed. On the other hand, a limitation of theoretical education was found in that there was no difference in emotional intelligence according to the major. Although empathic ability can be improved by education, the current curriculum has not improved it. This study has significance that it emphasizes the need for supplementing the curriculum, like practice or utilizing art media.

The purpose of this study is to investigate the relationship between the perception of dying with dignity and the quality of life based on the opinions of the Korean populations. The participants were selected using a stratified proportional allocation method and 1,000 adults aged between 19 and 74 years from 17 municipalities and provinces in Korea. The questionnaire consisted of 2 demographic items; 26 items on the quality of life scale; and 57 items on the perception of dying with dignity. The statistical methods used included frequency analyses, independent sample t-tests, and correlation analyses. The results showed that the quality of life was highest for the social life quality item, and that the participants who had experienced a death in the family were more likely to have statistically lower quality of life in physical, psychological, environmental, and social areas. In terms of the participants' perception on dying with dignity, the score for death preparation was the highest; specifically, the score for psychological/economic burden reduction was the highest. The quality of life of the participants showed a positive correlation in all aspects of the perception of dying with dignity: physical symptoms and control, death preparation, death environment, family and social relations, hospital treatment, psychological dignity, and spirituality. Other studies conducted with middle-aged populations showed that their quality of life was higher when they perceived the acceptance of death is important and were willing to participate in death preparation education. Therefore, in order to improve the quality of life and have a positive influence on the participants, educational programs on death preparation and dying with dignity considering all the areas of the perception of dying with dignity should be provided.

This study was a descriptive exploratory study to provide a foundation for improving the healthy working environment in Korean Red Cross Blood Center workers. A total of 215 surveys were collected from September 8 to October 31, 2020. Chi-squared test or Fisher's extract test, Independent t-tests, and Multiple Logistic Regression were performed with the SPSS 19.0 statistical program. We conducted multiple logistic regression analysis to evaluate the relationship between positive psychology capital and job stress with the perceived health status. The good perceived health status was 35.3%(N=76). When adjusted for related factors, the general characteristics and work characteristics were not related to perceived health status, and the positive psychological capital and job stress were significantly different between healthy and unhealthy groups (p<.001, p<.001). As positive psychology capital increased by one unit, the odds ratio of good health groups for subjective health increased significantly 1.1 times [95% Confidence interval (CI: 1.0-1.1)] and the odds ratio for good health groups for subjective health status decreased by 0.9 times [95% Confidence interval (CI: 0.8-0.9] as job stress increased by one unit.

Purpose: This study was to investigate the dentists' experience and awareness of foreign body ingestion and aspiration during dental prosthetic treatment. Materials and Methods: A survey of 157 dentists working at 108 dental institutions in Daejeon and Chungcheong provinces was carried out and frequency analysis was conducted. Chi-square test was conducted to find out the difference between the sociodemographic data and experience of foreign body ingestion and aspiration of patients and independent sample t-test was conducted to find out the difference in awareness depending on whether receiving related education. Results: The percentage of dentists experiencing dropping foreign body into patients' oral cavity was 99.4% and the percentage of dentists experiencing foreign body ingestion and aspiration of patients was 53.5%. There were more dentists who experienced foreign body ingestion and aspiration of patients in male than female, longer working career, and general practitioners than specialists (P < .05). 50.3% of the respondents received related education. When they receive related education, they had low degree of concern, high confidence in coping with situations, and low willingness to receive education in the future (P < .05). Conclusion: The percentage of foreign body dropping was 16% higher in prosthetic treatment than general treatment. The percentage of dentists with experience of foreign body ingestion and aspiration of patients was 53.5%. Among them, 92.9% experienced foreign body ingestion of patients and 7.1% of them experienced foreign body aspiration of patients.

A fixed-precision-level sampling plan was developed to establish control of the two-spotted spider mite, Tetranychus urticae, in two strawberry greenhouses (conventional plot, natural enemy plot). T. urticae was sampled by taking a three-leaflet leaf (1 stalk) from each plant (3 three-leaflet leaves) from each sampling position. Each leaflet was divided into three different units (1-leaflet, 2-leaflet, and 3-leaflet units) to compare relative net precision (RNP) values for selection of the appropriate sampling unit. The relative net precision values indicated that a 1-leaflet unit was more precise and cost-efficient than other units. The spatial distribution analysis was performed using Taylor's power law (TPL). Homogeneity of the TPL parameters in each greenhouse was evaluated by using the analysis of covariance (ANCOVA). A fixed-precision-level sequential sampling plan was developed using the parameters of TPL generated from the combined data of the conventional plot and natural enemy plot in a 1-leaflet sampling unit. Sequential classification sampling plans were also developed using the action threshold of 3 and 10 mites for pooled data. Using the results obtained in the independent data, simulated validation of the developed sampling plan by Resampling validation for sampling plan (RVSP) indicated a reasonable level of precision.

The purpose of this study was to determine if a geriatric injury would have a statistically significant relationship with the spatial safety within a specific region. To achieve the objectives of this study, an independent sample t-test and One-way ANOVA were performed to verify difference in mean value of regional safety grade, depending on the injury intentionality, injury location, activities at the time of injury, and injury mechanism, in 6,572 geriatric injury patients by combining the National Hospital Discharge Patients Injury Survey data and regional safety index data. The results of statistical validation suggested that there was no difference in the mean value of regional safety grade by sub-group with respect to the injury intentionality. However, a statistically significant difference was observed in terms of the mean value of regional safety grade in each sub-group with regard to the injury location, activities at the time of injury, and injury mechanism in connection with some areas of the regional safety index. Based on the results of such analysis, we derived and presented 3 implications related to policies and practice for the prevention of geriatric injury and a reduction of its occurrence rate in light of spatial safety after a discussion of the results through a comparison with previous studies that examined individual areas.

The purpose of this study is to analyze the effects on particulate concept formation based on abductive reasoning model for elementary science class. For this study, an author selected two groups in the sixth grade. One group is an ordinary textbook-based control group (N=26) and the other group is an abductive reasoning model-based treatment group (N=26). After twelve lessons, the scores of Concepts Test for Gas were analyzed by t-test and two-way ANOVA. The result of t-test showed both the control and treatment groups have higher score than before they take the lesson. But after the lesson, an author found out that the treatment group had higher score than that of the control group. And compared to the number of particles expressed, the number of the treatment group were higher than that of the control class. The two-way ANOVA result revealed that the interaction effect between their cognitive level and treatment was not significant. And regardless of the level of cognition, the scores of treatment group are higher than those of control group. Therefore, abductive reasoning model-based elementary science class were found to be more effective for particulate concept formation. Based on the results, an author concluded that abductive reasoning model is very effective in teaching particulate concepts to elementary students.
