The study aims to design an integrated remote controller, which is an increasingly essential device in the home, for more convenient use. For this purpose, an alternative user interface (UI) design was developed by applying the user interface system of a popular existing product to an integrated remote control highly usable and easy to learn for domestic use, and the usability was evaluated. For the existing popular product, a cellular phone was selected, the operation method of which is similar to the stick-type integrated remote control for which the user interface design was to be developed in this research. Common characteristics of the UI of the selected cellular phone were derived and the characteristics were applied as much as possible to the design of a stick-type integrated remote control. The prototype of the alternative design, which was simulated with Flash, went through two pilot tests for further improvement before making the final experimental prototype. Based on the results, prototype buttons that improved the feeling of use in terms of physical operation and feedback were made, and the usability of the new UI design of a stick-type integrated remote control for domestic use were evaluated with 41 university students in their 20s. According to the results of the experiment, the newly designed stick-type integrated remote control based on the UI of an existing product may improve the usability of remote controls and the outcome of this study is expected to provide a good model for R&D of new UI designs of stick-type integrated remote controls for domestic use.

The purpose of this study was to analyze the questions of earth science knowledge presented in elementary science textbooks. In group activities, The questions were created by preservice elementary teachers assuming that they were teaching the earth science knowledge in science education classes at university of education. Types, frequencies, and sources of the cognitive background knowledge of the questions were analyzed. The results demonstrated the followings. First, types, concentrations, and sources of the cognitive background knowledge of the questions were different depending on the domains of earth science. Specifically, in astronomy domain, the frequencies and concentrations of the questions showed different trends compared with other domains in its individual lessons. It suggests that instructional strategies that reflected the difference found in each lessons be appropriately designed and used. Second, it was found that 'schools' was the most dominant sources of the cognitive background. 'Friends' were also found to be very important sources, thus promoting students' interaction with their peers would become an important strategy in science teaching. It was also found that mass media such as 'internet' and 'TV' were roughly rated the same as 'schools' which illustrated that mass media could be utilized in science instruction. Third, since types, concentrations, and frequencies of the questions were diverse in the lessons of units, it is suggested that diverse instruction strategies also be taken into account as an educational approach in teaching the subjects in teacher education.

As the share of leisure culture increases these days, expectations are rising for the high quality of culture while increasing interest in leisure and tourism. The percentage of the population going on weekend trips to broaden the horizons of elementary, middle and high school students has continued to rise in proportion to the expectations for cultural enjoyment. We expect that visitors' weekend family activities will include relaxing, playing and educational purposes. Recent educational programs have moved from the past where only children were allowed to be onsite, to a shared style in which parents can engage in educational activities, potentially leading to the implicit involvement of family ties and family elasticity. The effects of education are not expressed by the period that ends in a single moment of experience, but by the continuity of training and experience. The same holds true for family affinity, communication and empathy. Providing opportunities for family experience and education is a national responsibility for broken family and restoring solidarity with the growing number of single-person households. Furthermore, it is a duty of museums and galleries today, and it is necessary to come up with methods to enhance family solidarity and family affinity. In particular, it is imperative to develop and provide educational programs for educational purposes at the Education Museum, and to develop " education for family " at the social level. This paper aims to analyze the results of all family participating education programs provided by family education programs at the Education Museum through family surveys and interviews, and to enhance the activation of family types education programs more actively.

Artificial intelligence (AI) is already being utilized in certain personnel selection processes in organizations; AI will eventually make even final decisions for personnel selection. The present study investigated potential job candidates' perceptions of an AI recruiter by comparing the selection procedures carried out by an AI recruiter to those carried out by a human recruiter. For this study college students in South Korea were recruited. They were each shown one of two recruitment scenarios (human recruiter vs. AI recruiter; between-subject design) followed by questionnaires measuring their satisfaction with the selection procedures and procedural justice, their trust in the recruiter, and their belief in a just world. Results show that potential job candidates were more satisfied with the selection procedures used by the AI recruiter than the human recruiter; they perceived the procedures as fairer than those used by the human recruiter. In addition, potential job candidates' trust in the AI recruiter was significantly higher than their trust in the human recruiter. This study also explored whether potential job candidates' perceptions of the AI and human recruiter were contingent upon their beliefs in a just world. The present study suggests a direction for future research.

This study was performed to analyze empowerment process of the disabled. Participants were 11 disabled college students and they were individually face-to-face in-depth interviewed until data were saturated. This study used the grounded theory approach based on Strauss and Corbin(1998). With the qualitative constant comparative analysis, 105 concepts, 22 subcategories, and 12 categories were generated. In the axial coding, a paradigm model was proposed as follows: The central phenomenon of the empowerment process of the disabled adolescents was 'Rising from the Limits'. The causal conditions were 'Just living' and 'realizing disabilities'. The contextual conditions were 'Being excluded', 'But wishing', and 'Breaking down'. The intervening conditions were 'Without giving up' and 'Taking support'. The action/interaction strategies were 'Grasping own lifestyle' and 'Being proactive'. The consequences were 'Acquiring the self-control', 'Getting generosity', and 'Participating in society'. In the selective coding, the core category was 'to live together stately with grasping own lifestyle pro-actively as the disabled'. Based on the core category, three types and 4 stages of the empowerment process of the disabled adolescents were found. The types were 'Social change oriented type', 'Self-development oriented type', and 'Passive effort oriented type' and the stages took 'Isolation stage', 'Rising stage', 'Mastering stage' and 'Stately being together stage'. In particular, this process had the circulation structure of which these 4 stages are not terminated, and developed and repeated. In conclusion, these results convey to us the understanding and knowledge about empowerment process of the disabled as their healthy -whole and unique- development process. And some implications and suggestions for the social work services and theories about the disabled focusing on the pre-adulthood period.

In this paper, we propose a design and implementation method of speed quiz content that can be driven by a social robot capable of interacting with humans, and a method of developing an intelligent module necessary for implementation. In addition, we propose a method of implementing speed quiz content through the process of constructing a map by arranging and connecting intelligent module blocks. Recently, software education has become mandatory and interest in programming is increasing. However, programming is difficult for students without basic knowledge of programming languages to directly access, and interest in block-type programming platforms suitable for beginners is growing. The block-type programming platform used in this paper is a platform that supports immediate and intuitive programming by supporting interactions between humans and robots. In this paper, the intelligent module implemented for the speed quiz content was used by blocking it within a block-type programming platform. In order to implement the scenario of the speed quiz content proposed in this paper, we implement a total of three image-based artificial intelligence modules. In addition to the intelligent module, various functional blocks were placed to implement the speed quiz content. In this paper, we propose a method of designing a speed quiz content scenario and a method of implementing an intelligent module for speed quiz content.

In this study, we analyze the strengths and limitations of student convergence education and teacher-training programs offered by a science education institute in the capital region and provide suggestions for organizing and running similar programs in other science education institutes and schools. Reviews of relevant literature and interviews with internal and external expert groups were conducted, and an analytic framework was developed. Based on the framework, we collected data using focus group interviews and email communications with experts. The data were analyzed using both qualitative and quantitative methods within two areas, namely, convergence education programs for students and teacher-training programs. The data analysis results revealed the status of student convergence education and teacher-training programs in the institute. Furthermore, we also provided suggestions for improving programs in other informal science education institutes and schools through the interaction between the two areas in the framework and educational and social needs.
