Objective: This study aimed to explore the effect of the national preschool curriculum on children's development in Korea, focusing on teachers' daily practice. By comparing the effect of the teachers' curriculum practice to that of quantitatively measured free play, it tried to add practical implications beyond the statistical significance. Methods: Participants were 512 three-year-old children who participated in the Panel Study of Korean Children and their teachers. National curriculum practice and free play time at the age of three was put in the hierarchical linear regression models to discover children's developmental outcomes at the age of four, in domains of language, cognitive development, and social development. Results: Results demonstrated the significant positive influence of national curriculum practice on every domain of developmental outcomes. However, no facilitative influence of free play time was observed. Conclusion/Implications: The importance of teachers' practice of the national curriculum was emphasized. It was implied that the quantity of free play time itself did not assure the sound development of children. Policy implications were discussed regarding teacher practice and education.

In this paper, new spectrum sensing schemes based on analog/RF front-end processing are introduced for IoT wireless sensor networks. While the conventional approaches for wireless channel cognition have been issued in signal processing area, the RF spectrum cognition concept makes it feasible to achieve cognitive wireless sensor networks (C-WSNs). The spectrum cognition at RF processing is categorized as four kinds of sensing mechanisms. Two recent reseaches are described as promising candidates for the C-WSN. One senses spectrum by the frequency discriminating receiver, the other senses and detects from the frequency selective super-regenerative receiver. The introduced systems with simple and low-power RF architectures play dual roles of channel sensing and demodulation. simultaneously. Therefore, introduced spectrum sensing receivers can be one of the best candidates for IoT wireless sensor devices in C-WSN environments.

Serious games are developed under particular purpose. This study provides a theoretical background on serious games for social change as a basis for future experiments and practice. By examining the elements of games and related theories, narrative immersion and critical participation are identified as the two main experiences of games, which are realized through role play. Based on educational theories for behavioral and cognitive change, this study suggests to use role play as a strategy on serious games for social change. Analyzing the cases of serious games in Korea, this study concludes that participants are able to experience the context of the situation through role play.

Objective : This study aimed to investigate the mediating effect of play on the relationship between toddlers' sleep habits and problem-solving. Methods : In total, 1,734 participants were selected from the 3rd wave of the Panel Study on Korean Children. A structural equation modeling approach was utilized to examine the relationship among toddlers' play, sleep habits, and problem-solving, as well as to investigate the mediating effect of play. Results : The monthly age of the study participants ranged from 23 to 32 months, with 885 (51.0%) boys and 849 (49.0%) girls. The indirect effects of play on problem-solving skills (β = 0.137, p = .006) were statistically significant, but the direct effects of sleep habits on problem-solving skills (β = -.015, p = .871) and the total effect (β = 0.122, p = .057) were not significant. Conclusion : This study indicated that sleep habits did not have a direct effect on problem-solving ability, but that the indirect effects were significant and fully mediated by play. Incorrect sleep habits can negatively affect lifelong development. Therefore, parents would need to be aware of whether their child is developing good sleep habits during the toddler age.

Studies on aesthetic experience in games mostly focus on engineering approach centered on structural determination of specific target within the game as well as humanistic·social approach in forms of artistic conversation on game play experience. This paper have established a theoretic guideline regarding the progress of aesthetic experience which allows analysis from the perspective of player experience acquired during game play. Based on such guideline, the study classifies cognitive data (Eye-Tracking, Playing Action, Facial Expression) on aesthetic experience and suggests the methods to measure such data. By deducing errors and points to be considered related to measuring methods through pilot tests, this study will contribute to the execution of empirical study focused on player perspective.

The purpose of this study is to investigate the effect of a community-based cognitive stimulation program on cognitive function and subjective memory in the elderly with mild cognitive impairment. This study was applied by selecting 15 users who understood the purpose of this study and agreed to participate in the shelter program for more than 3 months from April 2019 to August 2019 at the D Dementia Center in G located, Gyeonggi-do. The program consisted of a total of 36 cognitive stimulation programs 3 times a week a total of 3 months. Cognitive stimulation program stimulates cognitive function through various activities such as orientation reinforcement, cognitive training, recall, music, art, and physical play, and is used for the purpose of improving social function. It consists of folk songs, percussion instruments, national gymnastics, dance, games, and traditional games. As a result of the cognitive stimulation program, the average cognitive function increased by 2.13 points from 26.33 points before implementation to 28.46 points after implementation, and a statistically significant result was obtained (p=0.000). Subjective memory decreased by 3.53 points from the average of 7.13 points before the cognitive stimulation program was implemented to 3.60 points after the implementation, and a statistically significant result was obtained (p=0.000). It can be confirmed that this works. Dementia is leading to a cost burden, and congnitive function decreases the aqulity of life. It brings various burdens. It is necessary to study cognitive stimulation programs applied to various environments in the future.

Purpose: In the restaurant sector, it has been known that consumers' positive perception of brands influences their positive WOM intention, and information sources play an important role in increasing credibility by enhancing consumer awareness and developing differentiated brands. This study examines the effects of information sources (e.g., advertisement, WOM, SNS) on trust (cognitive and affective) and, WOM and eWOM intention in the restaurant context. In the model, cognitive and affective trust play mediating roles in the relationships between information sources (e.g., advertisement, WOM, SNS) WOM and eWOM intention. Research design, data, and methodology: Research models and hypotheses were developed according to the research direction. The survey questionnaire items were developed and used appropriately according to the contents of this paper based on prior studies. All constructs were measured with multiple items developed and validated in prior studies. A total of 502 responses were collected from an online survey. The research model was evaluated using SmartPLS 4.0. Frequency analysis was performed to understand the demographic characteristics of the survey respondents. The reliability, convergent validity, and discriminant validity were assessed using measurement model analysis. The proposed model was verified using the structural equation model. Results: Advertisement, WOM, and SNS information sources all had a positive effect on affective trust, whereas only WOM had a significant effect on cognitive trust. In addition, affective trust had a positive effect on cognitive trust and eWOM intention but did not affect WOM intention. Finally, cognitive trust was found to have a positive effect on both WOM intention and eWOM intention. Conclusions: This study redefines the concept of where restaurant service companies should focus when providing consumers with information about their products and services. As a result, the conceptual framework of positive word of mouth intention to increase new customer visits to the restaurant brand has been expanded. In addition, this study not only presents an information source management strategy for restaurant brands, but also presents practical implications for resource allocation guidelines for customer management in the restaurant sector.

This paper analyzes the central tenet of 'embodied cognition' approaches to the mind which emphasize the essential roles that the body and the environment play in cognitive processes. Those approaches can be best understood through the comparison with the neo-Cartesian conception of the mind, which views the mental and cognitive processes as the same with, or as being realized by the brain processes. However, we can also observe potential tensions among the 'embodied cognition' approaches. This paper highlights a tension between Shapiro's view of embodied cognition and Clark's view of extended cognition by reconsidering them against Block's dilemma of functionalism. Shapiro's view may be regarded as a chauvinistic form of functionalism, whereas Clark's view is a very liberal form of functionalism.

The library means to children a place where they find information necessary for them among a variety of knowledge and information to address their intellectual curiosity, which makes their lives wise and mature. There are not enough research materials understanding children's cognitive systems and behaviors in studies of a children's library with this necessity. This study divided and analyzed the behaviors of children, who were users into three types of reading in terms of information processing. First, it observed the types of reading depending on the stage of their cognitive development; Second, it analyzed the patterns of their behaviors through plays; and lastly, it presented the phases of their behaviors depending on the degree of an assistant's intervention. As a result of the study, the sensory system used and the space preferred differed depending on the stage of their cognition; there were differences in the patterns of their behaviors in each age group depending on the type of play; and there were differences in the children's ability of information processing depending on the assistant's ability. It is anticipated that there will be improvements of children's reading ability at the reading room in a better environment if the three types are considered in terms of information processing.

There have reports suggested that cerebral blood flow (CBF) has decreased in patients with both senile dementia of the Alzheimer's type and multi-infarct dementia, which are characterized by marked cognitive impairments. In addition, recent studies have demonstrated that decrease of CBF precedes the onset of multi-infarct dementia. These findings further suggest that chronic reduction of CBF may play an important role in the formation and progression of cerebral vascular dementia. Although transient cerebral ischemia, based upon vascular “reperfusion”, is apparently not paralleling the clinical condition, the transient cerebral ischemia model is one of the major methods investigated and the other is the cerebral embolism operation. Cognitive impairment and neuronal damages have been fully studied using these transient and/or embolic ischemia models. There are, however, few investigations focused the attention on the influence of chronic decrease of CBF on cognitive processes. In the present study, we have chosen a chronic ischemic model which is produced by permanent occlusion of bilateral common carotid arteries (2VO) in rats to investigate the neuronal damage and cognitive deficits through radial maze performance. We investigated furtherly the effects of tetramethylpyrazine (TMP), a constituent isolated from Ligusticum Chuanxiong on such a model.
