The purpose of this study was to examine changes in the rate of occurrence of challenging behaviors in young children according to their increase in age. The study is based on the responses of teachers in child care centers(N=246). They were asked which 38 types of challenging behavior occur most among ages 2, 3, 4, or 5 in young children's classrooms. The major results of this study were as follows. First, the occurrence rates of young children's challenging behaviors were classified into 5 clusters; decreased(Cluster 1, Cluster 2, Cluster 3), maintained(Cluster 4), or increased(Cluster 5) according to increases in their respective ages. Second, the behaviors such as throwing tantrums and biting, evident in Cluster 1, decreased very rapidly from a very high occurrence rate by age 3. The classroom culture maladjustment behaviors such as running aimlessly around the classroom and shouting, apparent in Cluster 2, had decreased rapidly from a high occurrence rate by age 4. The intentional classroom disruptive behaviors such as dropping objects to create noise and the peer culture maladjustment behaviors studied in Cluster 3 decreased gradually from a rate of medium occurrence by age 5. These results revealed the discontinuity which a few young children exhibit. Third, hurting others, observed in Cluster 4 maintained a low occurrence rate from age 2 until age 5. Using inappropriate language and threatening others in Cluster 5 increased gradually from a low occurrence at 2 to a high rate of occurrence at age 5. By carefully examining the change of young children's challenging behaviors on the basis of objective data in terms of the continuity/discontinuity and increased/decreased rate of diverse challenging behaviors, we will be better able help teachers and parents to plan the instruction, prevention and intervention of young children's challenging behaviors.

The purpose of this study was to determine types, causes and instructional methods of challenging behaviors perceived by mothers of young children with and without disabilities. Then it was also to determine influencing factors of mothers' socio-demographic variables and mothers' perceptions of types and causes of young children's challenging behaviors on using instructional methods perceived by the mothers. The subjects were 176 mothers of young children aged from two to six including 100 mothers of young children without disabilities and 76 mothers of young children with disabilities in Seoul and Gyeonggi Province. Results showed that first, there were significant differences in areas on internalized challenging behaviors and avoidance of social activities for the types of challenging behaviors. Second, on the cause of challenging behaviors, areas on children's behaviors and nature had significant differences between the groups. Third, on instructional method of challenging behaviors, there were significant differences on areas of establishing supportive environment and social and emotional strategies. Lastly, for the mothers of young children without disabilities, mothers' educational background and children's nature area as cause of challenging behaviors significantly affected instructional methods. For the mothers of young children with disabilities, family's income and others area as cause of challenging behaviors affected instructional methods. Developing practical application strategies were suggested based on the results. Research limitations and further research suggestions were also discussed.

This study was conducted to understand the current status associated with challenging behaviors of adults with developmental disabilities and review the perception of workers at lifelong education centers for the developmentally disabled. To that end, a survey and a focus group interview were conducted. The findings were as follows. First, 85.4% of people working at lifelong education centers for the developmentally disabled had experienced injury in the past year due to challenging behaviors, and those who experience injuries responded that they suffered burnout, psychological trauma, and considered changing jobs. Second, in terms of preemptive response by the organization to address challenging behaviors, 'securing individual space' and 'preemptive identification of causes of challenging behaviors' ranked the highest, with 87.5% of the respondents giving this answer, respectively. For follow-up measures, 81.3% of organizations answered that they hold meetings on individual cases and provide supervision. Third, in terms of suggestions for ways to address challenging behaviors, establishment of an organization-wide system and cooperation with related organizations were cited as needed.

The purpose of this study was to develop a reliable and valid instrument to assess Korean teachers' strategies for addressing challenging behaviors of preschoolers. The Teacher Strategy Questionnaire(TSQ) consisting of 34 items was developed with three theoretically driven factors(positive proactive, positive reactive, and negative reactive strategies). Participants were 238 preschool and daycare center teachers who responded to the TSQ. Validity and reliability of the TSQ were explored using Cronbach's $\alpha$, item analysis, and factor analyses. The reliability of the TSQ was relatively high, ranging from .74 to .85. No item needed to be eliminated. Among the three pre-structured factors of the TSQ, one positive proactive factor was identified as having two innate factors.

The purpose of this study was to investigate the effects of Adapted Physical Education Majors' perceived teacher competencies on the emotion reaction towards challenging behaviors of students with disabilities. In order to achieve the object of the study, the data collected from 413 sophomores, juniors, and seniors currently studying adapted physical education in schools located in Seoul, Gyeonggi, Gyeongnam, and Gyeongbuk, where they offer department of adapted physical education, was analyzed. As a measuring tool, Kwon (2008) and Han (2011) questionnaire for adapted physical education educators' perceived teacher competency and Oh, Seo & Kozub's (2010) questionnaire on the emotion reaction towards challenging behaviors of students with disabilities were revised, modified, and reconstructed. Data was processed using SPSS 21.0, and the exploratory factor analysis, reliability verification, difference verification, and multiple regression analysis were performed. The results are as follows. First, in terms of the analysis of emotion reaction based on demographic characteristics (sex, grade, disability in the family, friends with disabilities), sex, grade, and friends with disabilities displayed statistically significant difference on emotion reactions. Second, in terms of the effects of adapted physical education educators' perceived teacher competencies on the emotion reactions on towards challenging behaviors of students with disabilities, the parental education and the special activities of adapted physical education among the sub-factors of perceived teacher competencies affected significantly on emotion reactions, whereas the common knowledge on adapted physical education, curriculum lesson, and education knowledge by disability did not affect significantly on emotion reactions.

Identifying the speakers of individual utterances mentioned in textual stories is an important step towards developing applications that involve the use of unique characteristics of speakers in stories, such as robot storytelling and story-to-scene generation. Despite the usefulness, it is a challenging task because not only human entities but also animals and even inanimate objects can become speakers especially in fairytales so that the number of candidates is much more than that in other types of text. In addition, since the action of speaking is not always mentioned explicitly, it is necessary to infer the speaker from the implicitly mentioned speaking behaviors such as appearances or emotional expressions. In this paper, we investigate a method to exploit linguistic clues to identify the speakers of utterances from textual fairytale stories in Korean, especially in order to handle such challenging issues. Compared with the previous work, the present work takes into account additional linguistic features such as vocative roles and pairs of conversation participants, and proposes the use of discourse-level turn-taking behaviors between speakers to further reduce the number of possible candidate speakers. We describe a simple rule-based method to choose a speaker from candidates based on such linguistic features and turn-taking behaviors.

Purpose: This study aims to understand if heterogeneous news is evenly consumed and distributed on portals as it examines people's news use and engagement behaviors and news credibility. Focusing on the four behaviors of news use, i.e., viewing news by keyword search, viewing news from subscribed sources, viewing news from the list of most-viewed news, and reading comments, and the three behaviors of news engagement, i.e., sharing news, 'liking' or 'recommending' news, and posting comments, this study investigates the relation between each of the behaviors and portal news credibility. Research design, data and methodology: From 2022 News Audience Survey in Korea, this study conducts a regression analysis to investigate the relations between each behavior and news credibility. Results: The results show a positive relation for the former two news use behaviors and the latter two news engagement behaviors, and a negative relation for the latter two news use behaviors. Conclusions: The positive relations between active news use and engagement behaviors and portal news credibility indicate that news consumers are more likely to use and engage in attitude-consistent news rather than attitude-challenging news, implying that heterogeneous news is less likely to be consumed and distributed evenly on portals across all news users.
