The purpose of this paper is to investigate if any effects of GI cooperative learning method, which is compared to the effects of traditional competitive teaching-learning method on the students' academic attitude in middle school social studies classes. Conclusively, it is asserted to be a much more effective teaching-learning method. Some statistical evidences were gathered by questionnaire method just after the experimental classes being applied for a semester to the 241 first year middle school students in a small city. Using the t-test procedure, it is conformed that GI cooperative learning method can draw much more positive changes in the academic attitude of the students. In short, such positive changes in student's academic learning attitude can be related with the increase of self-trust in learning processes, the change in the conception of the subject, and the spontaneous interaction and verbal communication among the group members.

In aspect of HCI(Human Computer Interaction) gameplay is the procedure to solve the problem that gamers encounter in order to generate or discover a new rule to achieve gamers' goal. The goal of this research is to investigate the structure and understand the gameplay in aspect of affordance from ecological psychology rather than the traditional problem solving theory. This research selects App. game based on smart phone. Expert gamers participated in this experiment. We record all gameplay using audio and video device. We conducted protocol analysis as qualitative method based on the verbal report and action protocol during game playing. As result, gameplay based on affordance includes selection and relation. We found that subjects selected one thing at once with attention. Moreover, we found that there were two behaviors : exploratory action and performatory action. We believe that exploration, action, and transformation for affordance appear. The result of this research imply to suggest design guideline for game design methodology when designers develop game.

Practice parameters for non-pharmacological treatment of children and adolescents with pervasive developmental disorders are based on the scientific literature for evidence-based practices. Appropriate educational and behavioral interventions are important in improving the long-term outcome in pervasive developmental disorders. Early and sustained intervention appears to be particularly important. The goal for interventions is to gain pragmatic skills for verbal communication, playing with peers, daily living routines, self-management, and social adaptation. Appropriate involvement and collaboration with parents and family are essential for well-functioning intervention programs. The life-long nature of autism implies that the clinician should maintain an active role in long-term treatment planning and family support. Vocational training and training for more independent living are important for adolescents with autism. Professionals should be knowledgeable about local and national resources and opportunities for family support as well as support of the individual.

Electrolarynx(EL), battery operated vibrators which are held against the neck by on-off button, has been widely used as a verbal communication method among post-laryngectomized patients. EL speech can produce easily without need of any additional surgery or special training and be used with any other methods. This institute developed a neck-typed EL named "Blueton" in commperation with EL Company Linkus, which consists of 3 parts : Vibrator part, Control part, Battery part. In this study we evaluated the acoustic characteristics of the produced voices by Blueton compared with Servox-inton using MDVP. Three EL users (2 full time users, 1 part time user) were participated. The results revelaed that NHR higher in Servox than Blueton and intensity is higher in Blueton than Servox. The spectra for vowels produced by EL speakers are mixed signals combined with talkers' vocal output and electrolarynx noise. The spectra pattern is similar with two ELs. High, SPI index and vowel spectra from MDVP demonstrated characteristics of both electrolarynxes related to noise signal. This finding suggests that Blueton helps to provide one of useful rehabilitation options in the post laryngectomy patients.

Purpose: This study was conducted in order to provide basic data for development of a nursing intervention program needed in living successfully in elderly women's later years by examining the relationship among depression, death anxiety, and quality of life of elderly women. Methods: Subjects were 115 elderly women over 65 years old who were capable of verbal/nonverbal communication and could understand/answer the questionnaire in H region. Data collection was conducted after receiving written consent using a structured questionnaire. The data analysis was performed using descriptive statistics, t-test, ANOVA, Duncan's multiple range test and Pearson's Correlation Coefficient using the SPSS 12.0/WIN program. Results: Results of this study showed that the degree of depression in elderly women was $4.14{\pm}3.22$ on average and the degrees of death anxiety and quality of life were $2.41{\pm}0.55$ and $3.72{\pm}0.59$ on average, respectively. No significant correlation was observed between depression and death anxiety however, depression showed negative correlation (r=-.448, p<.001) with quality of life and death anxiety also showed negative correlation (r=-.219, p<.05) with quality of life. Conclusion: We can predict that depression and death anxiety negatively affect quality of life of elderly women.

In this paper, we found the usefulness of the deep belief network (DBN) in the fields of brain-computer interface (BCI), especially in relation to imagined speech. In recent years, the growth of interest in the BCI field has led to the development of a number of useful applications, such as robot control, game interfaces, exoskeleton limbs, and so on. However, while imagined speech, which could be used for communication or military purpose devices, is one of the most exciting BCI applications, there are some problems in implementing the system. In the previous paper, we already handled some of the issues of imagined speech when using the International Phonetic Alphabet (IPA), although it required complementation for multi class classification problems. In view of this point, this paper could provide a suitable solution for vowel classification for imagined speech. We used the DBN algorithm, which is known as a deep learning algorithm for multi-class vowel classification, and selected four vowel pronunciations:, /a/, /i/, /o/, /u/ from IPA. For the experiment, we obtained the required 32 channel raw electroencephalogram (EEG) data from three male subjects, and electrodes were placed on the scalp of the frontal lobe and both temporal lobes which are related to thinking and verbal function. Eigenvalues of the covariance matrix of the EEG data were used as the feature vector of each vowel. In the analysis, we provided the classification results of the back propagation artificial neural network (BP-ANN) for making a comparison with DBN. As a result, the classification results from the BP-ANN were 52.04%, and the DBN was 87.96%. This means the DBN showed 35.92% better classification results in multi class imagined speech classification. In addition, the DBN spent much less time in whole computation time. In conclusion, the DBN algorithm is efficient in BCI system implementation.

The purpose of the study was to determine the effects of the 8-week, 15-session group art therapy program on self-esteem and mental health status in chronic schizophrenic inpatients. The sample consisted of two groups of chronic schizophrenic inpatients: 10 patients with an average of total disease duration of 8.90 years who participated in a 8-week group art therapy program, and 8 comparison subjects with an average of total disease duration of 8.25 years who did not participate in the program. A pretest-posttest quasiexperimental design was used to assess self-esteem and mental health status at the beginning and at the end of the 8-week, 15-session group art therapy program. The time points for obtaining data were matched for both groups. The effectiveness of the 8-week group art therapy program was assessed by Rosenberg's Self-esteem Scale(Rosenberg, 1965) and SCL-90- R(Derogatis et al., 1973). SPSSWIN 8.0 was utilized for data entry and analysis employing Mann-Whitney U test. The findings of the study indicated the followings : (a) No significant differences were found between two groups in self-esteem and (b) The experimental group showed significantly lower scores in obsessive-compulsive symptom dimension and interpersonal sensitivity symptom dimension on the SCL-90-R than the comparison group after participating in the group art therapy program. In conclusion, the findings showed the possibility of applying group art therapy as an effective nursing intervention for patients with lack of verbal communication skills and social interaction to improve their interpersonal relationship.

Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by impairments in social interaction and verbal and nonverbal communication. Purpose: Determine the association between use of assisted reproduction technology (ART) and the risk of ASD among children. Methods: This case-control study included 300 participants (100 cases, 200 controls). The control group included women with a child aged 2-10 years without ASD, while the cases were women with a child aged 2-10 years with ASD. We used a researcher-made questionnaire. Data were analyzed using Stata ver. 14 at the 0.05 significance level. Results: In the univariate analysis, there was significant association between child sex, delivery mode, history of preterm delivery, history of using ART, and maternal age at child's birth and the risk of ASD. After the adjustment for other variables, this association was significant for male sex (2.66; 95% confidence interval [CI], 1.11-4.31; P=0.001) and history of using ART (4.03; 95% CI, 1.76-9.21; P=0.001). Therefore, after the adjustment for confounder variables, there was no significant association between ART and the risk of ASD among children (4.98; 95% CI, 0.91-27.30; P=0.065). Conclusion: After the adjustment for other variables, risk factors for ASD were male sex and history preterm delivery. Thus, there was no significant association between ART and the risk of ASD among children.

The patients visiting pediatric dental office have been being younger than the previous, and they were often combined with systemic disease. But, we aren't able to perform the verbal communication, because of their impediment and youthfullness. And, we can't carry out the behavior control via physical restraint, as the developed social structure and the attitude of children and their parents. So, the importance and concerning of conscious sedation using sedative medicine are increased by time and time. Among the various conscious sedation, Chloral Hydrate and Nitrous Oxide inhalation are most popularly used, and barbiturates, benzodiazepine, opioids and hydroxyzine are used often. But, these medications have some side-effects and adverse reactions, may be failed to sedate the children. And limited use of medically compromised patients, especially for ASA class III, IV or more dangerous patients. We, the Department of Pediatric Dentistry, Chosun University have met some dangerous situation due to unfavorable pharmacogenic reactions, but we can control the situation and get well healed results. The below results are common situations and their solutions during conscious sedation. 1. By the intravenous administration, thrombophlebitis is the most common side-effects, but it may be healed with time without any special treatment. 2. Under the definitive guidelines about conscious-sedation, we can perform a safe conscious sedation for ASA class III patients. 3. When adversed reaction of Benzodiazepine is occured, it could be cared effectively with benzodiazepine antagonist, named Flumazenil.
