The current study examines PCC (percentage of correct consonant), speech intelligibility, and oral motor function between the group of typically developing children and the group of children with Down's syndrome. To 15 children with Down's syndrome (mean CA: 9;7) and 15 typically developing children on receptive language age, the following tests were administered: K-WPPSI (2001), Picture Vocabulary Test (Kim et al., 1995), Oral and Speech Motor Control Protocol for total oral functional score (Robbins et al., 1987), DDK and Assessment of Phonology and Articulation for Children (APAC, Kim et al., 2007) for PCC and speech intelligibility. Pearson correlation coefficients were computed for the total oral functional score, PCC and DDK of each group. The statistical analysis showed that there is no significant difference in total functional score and DDK when IQ was controlled. There was a significant correlation between total oral functional score and PCC in the Down's syndrome group and a significant correlation between total oral functional score and intelligibility in the Down's syndrome group whether IQ was controlled or not. The findings suggest that both cognitive ability and overall oral motor function need to be considered for the intervention to enhance PCC or speech intelligibility of children with Down's syndrome.

A widely used social networking service like Twitter has the ability to disseminate information to large groups of people even during a pandemic. At the same time, it is a convenient medium to share irrelevant and unverified information online and poses a potential threat to society. In this research, conventional machine learning algorithms are analyzed to classify the data as either non-rumor data or rumor data. Machine learning techniques have limited tuning capability and make decisions based on their learning. To tackle this problem the authors propose a deep learning-based Rumor Detection Neural Network model to predict the rumor tweet in real-world events. This model comprises three layers, AttCNN layer is used to extract local and position invariant features from the data, AttBi-LSTM layer to extract important semantic or contextual information and HPOOL to combine the down sampling patches of the input feature maps from the average and maximum pooling layers. A dataset from Kaggle and ground dataset #gaja are used to train the proposed Rumor Detection Neural Network to determine the veracity of the rumor. The experimental results of the RDNN Classifier demonstrate an accuracy of 93.24% and 95.41% in identifying rumor tweets in real-time events.

Software testing is an important phase as it ensures the software quality. The software testing process comprises of three steps: generation, execution, and evaluation of test cases. Literature claims the usage of single and multiple 'Unified Modeling Language' (UML) diagrams to generate test cases. Using multiple UML diagrams increases test case coverage. However, the existing approaches show limitations in test case generation from UML diagrams. Therefore, in this research study, we propose an approach to generate the test cases using UML State Chart Diagram (SCD), Activity Diagram (AD), and Sequence Diagram (SD). The proposed approach transforms UML diagrams into intermediate forms: SCD Graph, AD Graph, and SD Graph respectively. Furthermore, by integrating these three graphs, a System Testing Graph (STG) is formed. Finally, test cases are identified from STG by using a traversal algorithm such as Depth First Search (DFS) that is an optimization method. The results show that the proposed approach is better compared to existing approaches in terms of coverage and performance. Moreover, the generated test cases have the ability to detect faults at the unit level, integration, and system level testing.

Fast decision support systems and accurate diagnosis have become significant in the rapidly growing healthcare sector. As the number of disparate medical IoT devices connected to the human body rises, fast and interrelated healthcare data retrieval gets harder and harder. One of the most important requirements for the Healthcare Internet of Things (HIoT) is semantic interoperability. The state-of-the-art HIoT systems have problems with bandwidth and latency. An extension of cloud computing called fog computing not only solves the latency problem but also provides other benefits including resource mobility and on-demand scalability. The recommended approach helps to lower latency and network bandwidth consumption in a system that provides semantic interoperability in healthcare organizations. To evaluate the system's language processing performance, we simulated it in three different contexts. 1. Polysemy resolution system 2. System for hyponymy-hypernymy resolution with polysemy 3. System for resolving polysemy, hypernymy, hyponymy, meronymy, and holonymy. In comparison to the other two systems, the third system has lower latency and network usage. The proposed framework can reduce the computation overhead of heterogeneous healthcare data. The simulation results show that fog computing can reduce delay, network usage, and energy consumption.

Purposes of this study were to explore the process of experience that science teachers go through when participating in peer coaching meetings to improve teaching ability and to find out factors that affect each process of experience. The data were collected through recording of peer coaching meetings, videotapes of science class, and interviews. All the data were analyzed after transcription. The results of the study showed that even though Teacher K broke the ice and formed consensus among the peers by developing Content Representation (CoRe) at the beginning of the meetings, he became self-defensive rather than receptive of peers' opinions on the recorded class at the discussion session. But as the peer coaching went on, he realized that peer coaching was not about evaluation but rather on improving his teaching ability. In turn, he was able to look at his teaching in a more objective point of view and accepted suggestions from peer coaching discussion. The self-reflection of Teacher K acted as the key factor in the efforts to improve his teaching ability. He sought the concrete alternatives through the class analysis with fellow teachers and showed major changes in his teaching practice from the language habits, pronunciation, and speed of his speech to the interaction with students and class design. However, there was little change in knowledge of curriculum and assessment due to his strong orientation to improve students' grades as an academic high school teacher. Likewise, it was found that while peer coaching exert a strong influence on instructional methods and strategies of Teacher K, his strong orientation to improve students' grades hinders a balanced development of subcomponents of PCK.

The purpose of this study is to verify empirically whether or not the linguistically creative problem-solving ability progress by developing and applying an enrichment learning program for the verbally gifted elementary school students. The total number of the verbally gifted students who participated in this study were 60 children. Half of them were subjects for evaluating the appropriateness of the enrichment learning program and the verbally creative problem-solving ability test developed by the researcher. The other half were divided into three groups for applying the teaching materials by Korean Educational Development Institute, the enrichment learning program by the present researcher, and the textbook enrichment program. The data were analyzed by the statistical method of repeated measures ANOVA. The results were as follows: First, the enrichment learning program developed by this researcher has greatly contributed to the advancement of verbally creative problem-solving ability. The program was especially effective in reading and writing, but not in speaking. second, the sub-category of reading includes factual, inferential·critical, and imaginary understanding. Among them, factual and imaginary understanding had not significantly advanced, while inferential·critical understanding had significant progression. Third, it was found that both logical and creative expression did not improve significantly by the enrichment learning program developed by the present researcher. Speaking is difficult to instruct. In conclusion, it was found that the systematic enrichment learning program was effective in developing language skills of the verbally gifted elementary school children. It was also proved to be more effective to teach them reading and writing together in everyday life. Also, it was turned out that continuous development of the enrichment learning program for the verbally gifted students is needed.

This study explored the cognitive characteristics and learning needs of economically disadvantaged gifted students. Gifted students(n=99), economically disadvantaged gifted students(n=43), and non-gifted students(n=50) participated in intelligence and creativity tests, and took self assessments of meta-cognition, epistemological beliefs, learning style preferences, and personal time usage. Superior abstract reasoning ability of economically disadvantaged gifted students was found because their scores on Raven's Test had risen rapidly compared to the other groups. Economically disadvantaged gifted students showed similar high scores as the gifted student on the Torrance Tests of Creativity Thinking-Figural, but not on Verbal. They were found to have a perception of the positive relationships among effort, learning abilities, and values of learning integrated knowledge with a general plan. However, they showed lower meta-cognitive control abilities than the gifted students in learning management and strategies, epistemological beliefs in value of rational operations, and time usage for learning. It is necessary to assign economically disadvantaged gifted students a task with various step by step methods of approach because these students prefer a new and creative task to difficult ones. Instruction plans such as developing language and meta-cognitive abilities and practical application of learning content was proposed.

This study was conducted from December 2015 to March 2016 to investigate the knowledge, attitude, and practice of baby foods in rural multi-cultural families. The survey included the general characteristics of households and infants, knowledge, attitude, and practice of baby food. The results indicated that the mean score of baby food knowledge was 3.79, 4.07 for attitudes, and the practice group was 25.0%. In the knowledge of baby food, the groups with a total number of two or more children, high educational background for both the father and mother, Chinese or Japanese nationality, high Korean language ability, and marriage for at least 6 or more years was higher (p<0.05). In the attitude of baby food, the groups with a total number of two or more children, a higher mother's Korean language, and the mother in charge of the baby food were higher (p<0.05). In the case of baby food practice, the groups the baby mother was from Japan and Cambodia, there was no occupation, and the mother was in charge of the baby food were higher (p<0.05). Knowledge and attitude according to the practice of baby food showed a higher knowledge (p <0.001) and attitude in the weaning practiced group than unpracticed. To produce baby food for infants in multi-cultural families, it is important to improve the Korean language ability of infant mothers who are in charge of baby food, and it is necessary to provide correct information related to infant formula utilizing the supporters of the neighboring mothers. In addition, it is necessary to provide customized education and support that is contingent upon the nationality of the native people while remaining mindful of the cultural implications of multi-cultural families.

It is noted that generally speaking, the expressing of actualization or non-actualization of events is not the main role of possibility for the utilization of expressions. In spite of this fact, it is possible to see many examples in which possibility expressions represent actual events, and impossibility expressions represent a type of non-actualization in relation to events. This effect can be described as a semantic extension, by which the participant-internal possibility is extended to actualization due to participant-internal factors, and the participant-external possibility is extended to the actualization due to participant-external factors. When the related possibility expressions are used in this extended sense, they express the dynamic evaluative meaning of 'desirability' of the realized event, while it is determined that when the impossibility expressions are used in this extended sense, they are seen to express the evaluative meaning of 'regretfulness' about the non-actualization of the event. In Modern Japanese, it is noted that there are a few expressions of ability and possibility. They can be largely divided into four types of expressions, according to their origins or uses of expression, which are 'ability verbs', affixes '-れる/られる(-reru/rareru)', '-できる(-dekiru)', and '-得る(-eru)'. They can all express participant-internal possibility and participant-external non-deontic possibility. While 'ability verbs', affixes '-れる/られる' and '-できる' can express participant-external deontic possibility, '-得る' cannot. However, '-得る' is the only possible element to designate the event of a epistemic possibility. Also, the four types of expressions have the usage of conveying 'actualization/non-actualization,' as is the case of the Korean language. However in Japanese, in fact adjectives cannot be associated with 'ability verbs' or 'ability affixes.' Thus the expressions of 'regrets' should in that case depend on the use contexts, unlike the expression 'adj+-지 못하다' as noted in Korean. The ability and possibility in Modern Chinese are mainly expressed by means of the four auxiliary verbs '能($n{\acute{e}}ng$)', '会(huì)', '可以(kěyǐ)' and '可能 ($k{\check{e}}n{\acute{e}}ng$)'. '能' and '会' along with '可以' can all convey participant-internal possibility. In this way '能' and '可以' can express participant-external possibility. Only '会' and '可能' can express epistemic possibility. As for 'actualization,' among the four auxiliary verbs, only '能' can represent actualization. Also, among the negatives of the four auxiliary verbs, only '沒能' can represent non-actualization.
