Purpose : The aim of this study was to determine the reliability of parents and therapists-assessed manual ability using the Manual Ability Classification System (MACS) for children with cerebral palsy Methods : Subjects were 136 children with cerebral palsy using rehabilitation programs in 16 welfare centers. Reliability was determined using the intraclass correlation coefficient (ICC). Parents and therapists assessed manual ability of children using MACS. Result : The 136 children (Male 73, Female 63) mean age was 7y 5mo years [range 3y 11mo - 13y 5mo]. The overall agreement between parents-assessed and therapists- assessed MACS was good (ICC = 0.84, 95% confidence interval 0.77-0.88). Conclusion : The MACS offers a reliable method for population-based research and communicating about the manual ability of children with CP.

Distributed Autonomous Robotic System (DARS) is defined as a system that independent autonomous robots in the restricted environments infer their status from pre-assigned conditions and operate their jobs through the cooperation with each other. In the DARS, a robot contains sensor part to percept the situation around themselves, communication part to exchange information, and actuator part to do a work. Especially, in order to cooperate with other robots, communicating with other robots is one of the essential elements. Because Bluetooth has many advantages such as low power consumption, small size module package, and various standard protocols, Bluetooth is rated as one of the efficient communicating technologies which can apply to small-sized robot system. In this paper, we will develop Bluetooth communicating system for autonomous robots such as DARS robots. For this purpose, The Bluetooth communication system must have several features. The first, this system should be separated from other robot parts and operate spontaneously and independently. In other words, this communication system should have the ability to organize and maintain and reorganize a network scheme. The next, this system had better support any kinds of standard interfaces in order to guarantee flexible applicability to other embedded system. We will discuss how to construct and what kind of procedure to develop the network system.

The purpose of this study was to evaluate barriers to pharmacists' routine work in community setting. A survey was given to 281 pharmacists who enrolled in 16-week clinical pharmacy educating program in continuous education center for advanced pharmacy at Seoul National University. Three main questions that pharmacists were asked to answer were: (1) difficulties on dispensing prescription, (2) difficulties on communicating with doctors, (3) most difficult disease on patients counseling. The response rates for the survey were more than 60 % for each three questions (62.63 %, 63.7 %, and 64.41 %, respectively). The top three barriers to dispensing prescription were lack of professional knowledge about medications, prescription error and its solving ability and patient counseling. The top three barriers to communicating with doctors were lacking of opportunity to discuss about patients' medication due to unavailability of doctors, doctors' attitude using authoritative manner, and a pharmacist's lack of knowledge. The top 4 most difficult diseases on patients counseling were cardiovascular disorders, dermatologic disorders, endocrinologic disorders, and psychiatric disorders.

The purpose of this study was to investigate the effect of type of values on coping stress through communication ability. The data for the study were collected from February 1 to 15, 2019, and the participants were collected through online questionnaires in the twenties who voluntarily participated in the study. The final data used in this study were 324. The research method was cross - sectional questionnaire survey. The analysis was done using SPSS 18.0, descriptive statistics, Pearson correlation, multiple regression and median effect analysis. A total of 324 people participated in the study, 38% of men and 62% of women were female. The results of this study showed that the collectivism values were positively correlated with individualism values (r = .224, p<0.01), emotional stress coping style (r = .266, p <), And emotion - centered stress coping was correlated with problem - oriented stress coping (r = .369, p <0.01). Those who had a collectivist value had a significant influence on the type of problem - centered stress coping(${\beta}=.271$, p<0.01), and the communication ability showed a perfect mediating effect($R^2=.310$,${\beta}=.113$, p>0.05). According to the results of this study, stress coping in the twenties suggests a program that fosters individualized communication ability.

The purposes of this study were to examine inter-rater reliability of the Manual Ability Classification System (MACS) by children's age and to identify the correlation between the MACS and the Gross Motor Function Classification System (GMFCS) in children with cerebral palsy (CP). Twenty-six children with CP older than two years participated. Children with CP were classified according to the MACS and the GMFCS by two physical therapists. Inter-rater reliability was analyzed using the Intraclass Correlation Coefficients (ICCs). The results showed that the reliability of the MACS for children aged 2~3 years was .88 and for children aged above 4 years was .98 (p<.05). Children with quadriplegia had a higher level of MACS than children with spastic hemiplegia and diplegia. A moderate relationship between the MACS and the GMFCS was found in all children (rater 1, r=.631; rater 2, r=.438). The MACS will be used for classification of children with CP according to the manual abilities. Thus, it offers a reliable method for communicating between therapists about the manual ability of children with CP who are older than 2 years.

Social media play a significant role in communicating information across the globe, connecting with loved ones, getting the news, communicating ideas, etc. However, a group of people uses social media to spread fake information, which has a bad impact on society. Therefore, minimizing fake news and its detection are the two primary challenges that need to be addressed. This paper presents a multi-modal deep learning technique to address the above challenges. The proposed modal can use and process visual and textual features. Therefore, it has the ability to detect fake information from visual and textual data. We used EfficientNetB0 and a sentence transformer, respectively, for detecting counterfeit images and for textural learning. Feature embedding is performed at individual channels, whilst fusion is done at the last classification layer. The late fusion is applied intentionally to mitigate the noisy data that are generated by multi-modalities. Extensive experiments are conducted, and performance is evaluated against state-of-the-art methods. Three real-world benchmark datasets, such as MediaEval (Twitter), Weibo, and Fakeddit, are used for experimentation. Result reveals that the proposed modal outperformed the state-of-the-art methods and achieved an accuracy of 86.48%, 82.50%, and 88.80%, respectively, for MediaEval (Twitter), Weibo, and Fakeddit datasets.

Our study goal is to find out how the table height influences functional ability of upper extremity to patients with stroke when they are having therapy. In this study, we tested forty patients with stroke at the age of over sixty-five who do not have visual, auditory disability and have no difficulty in communicating and moving things by using upper extremity. And they were able to pinch grip in hospital. We used occupational table for occupational therapy as Lab Materials. We also used cube and pegs board to test upper extremity functional ability. We used occupational table for occupational therapy as Lab Materials and we used cube and pegs board to test upper extremity functional ability. The method is that we measured the recommended table height that takes the subjects' size into consideration and patients' preferred table height and therapists' preferred table height and we applied them and then we have done a comparative analysis and set significance level(p<0.05). As the result, we found the Statistically significant between the recommended height and the other two, which are patients' preferred height and therapists' preferred height. We also discovered that functional ability of upper extremity varies significantly depending on each table height. We came to a conclusion that the table height had effects on the upper extremity functional ability of patients with stroke who are over sixty-five years old. It is therefore considered that the proper table height is important to improve upper extremity functional ability of patients with stroke for their physical therapy.

In industry areas, a lot of factories and process plants need network for processing data acquired from field and for communicating between sensors or actuators or field controllers. Most of the industry networks are based on wired solutions. But, recently, a lot of factories and process plants are moving into wireless solutions since they have some advantages compared with wired one. In this paper we first review the characteristics of wired and wireless network technologies and introduce the new technique called wireless sensor network (WSN). And then we describe the wireless sensor node system designed by us for WSN which has the ability of small size, flexibility and low-power consumption and embedded into the Bar-code scanner to communicate each other. Finally, we conclude this paper by showing that wireless industry network can be constructed with wireless sensor network without large change of traditional wired topologies through experiment using wireless sensor nodes.

Recently, the number of students to choose to study in Australia has been increasing significantly. The purpose of this study is to examine how Korean primary school children perceive their own English language learning and cultural adaptation in Australia. A questionnaire survey was conducted with 34 Korean children aged 8-13 who were attending primary schools in Brisbane, Queensland. The study results show that they made diverse efforts to learn English language and culture in Australia, such as making English-speaking friends, watching TV/video/DVD, reading English books, and studying with a foreign tutor. Their English listening and writing abilities were thought to be improved most, followed by speaking, reading and cultural understanding after studying in Australia. The subjects were mostly satisfied with their study and life in Australia but they had difficulties with communicating in English, homesickness, foods, weather, insects, and discrimination. In particular, they had problems with understanding classes conducted all in English and participating in the classroom activities due to their low level of English ability and understanding of Australian classroom culture. The findings of this study have pedagogical implications for educators both in Australia and Korea.
