This study intends to derive play attribute words to describe the nature of play by analyzing the correlation between play facilities and play attribute words. To investigate play attributes at playing facilities and supplement areas of weakness can provide a balanced play environment. Play attributes words were compiled via a literature review and the importance of each play attributes word was surveyed by experts. The keywords explaining play derived from news articles and references are defined as play attributes words. These words were classified into six broad categories and twenty-six sub-categories. The importance of major play attribute words show: Communication (0.268%) > Imagination (0.201%) > Amusement (0.190%) > Development (0.167%) > Learning (0.108%) > Intelligence (0.067%). Experts have recognized the most important elements are communication and imagination. Each play attribute associated with an amusement facility was separately identified in the amusement facilities installed in 114 children's parks in Seoul. Of the play attribute words, the amusement facilities at Seoul's Children's Park reflected a high frequency in 'development'. Furthermore, the importance of major playing attribute words such as 'Communication' and 'Imagination' were not fully reflected in cognitive play facilities. Therefore, it was judged that there is a need to actively introduce these attributes. This study proposed future improvements by determining weaknesses of amusement facilities in children's parks and analyzing the features and functions of play so as to suggest future improvements.

인터넷이 대중화대면서 온라인 쇼핑이 가능해졌고 구매자들은 인터넷을 통해 구매와 관련 된 경험, 서비스 등을 다른 사람들과 공유할 수 있게 되었다. 인터넷 쇼핑의 특성상 제품을 직접 눈으로 보고 만져 볼 수 없기 때문에 온라인 구전(Online Word of mouth)이 상품 구매 판단의 잣대로 활용되고 있다. 따라서 본 연구에서는 온라인 쇼핑몰에서 구전 정보 특성이 구매자들의 인지된 구전 정보 가치에 영향을 미치는지 실증적으로 분석하였다. 구전정보의 객관성, 관련성, 신빙성, up-to-dateness는 인지된 구전정보가치 즉 구매 불확실성 감소에 긍정적인 영향을 주었다. 구매 불확실성 감소는 온라인 쇼핑몰의 신뢰에 긍정적인 영향을 미쳤다.

최근 무선 네트워크 서비스의 수요가 증가함에 따라 낮은 비용, 간편한 설치 그리고 높은 대역폭 특성을 가지는 무선랜 (WLAN)을 기반으로 한 사내 네트워크 구성이 학교 및 기업을 중심으로 증가하고 있다. 이로 인해 사내 네트워크를 통한 랩탑 (Laptop), 넷북 (Notebook), 스마트 폰 (Smart Phone), 그리고 UMPC (Ultra Mobile Personal Computer)등 휴대용 단말을 이용한 스트리밍 서비스의 수요가 증가하고 있다. 하지만 무선랜 환경은 사용자 이동에 의해 핸드오버가 발생할 경우, 이동할 대상 네트워크의 혼잡 상태를 고려하지 않는다. 따라서 이동할 네트워크에 빠르게 적응하지 못함으로써 패킷 손실에 의한 서비스의 불연속성 문제가 발생할 수 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 핸드오버 이전에 이동 대상 네트워크의 혼잡 상태를 인지하여 전송률을 조절함으로써, 스트리밍 서비스의 불연속성 문제를 해결하는 적응적인 스트리밍 시스템을 설계 및 구현하였다. 제안하는 시스템은 핸드오버 이전에 이동 대상 네트워크의 가용대역폭을 측정하여 혼잡 상태를 인지하고, 측정한 가용대역폭 값을 기반으로 전송하는 프레임의 수를 우선순위에 따라 차등적으로 조절하여 전송률을 조절하였다.

We used holes defined by color similarity (Experiment 1) and binocular disparity (Experiment 2) to study how the inner contour of an object (i.e., boundary of a hole in it) is encoded in visual working memory. Many studies in VWM have shown that an object's boundary properties can be integrated with its surface properties via their shared spatial location, yielding an object-based encoding benefit. However, encoding of the hole contours has rarely been tested. We presented objects (squares or circles) containing a bar under a change detection paradigm, and relevant features to be remembered were the color of objects and the orientation of bars (or holes). If the contour of a hole belongs to the surrounding object rather than to the hole itself, the object-based feature binding hypothesis predicts that the shape of it can be integrated with color of an outer object, via their shared spatial location. Thus, in the hole display, change detection performance was expected to better than in the conjunction display where orientation and color features to be remembered were assigned to different parts of a conjunction object, and comparable to that in a single bar display where both orientation and color were assigned into a single bar. However, the results revealed that performance in the hole display did not differ from that in the conjunction display. This suggests that the shape of holes is not automatically encoded together with the surface properties of the outer object via object-based feature binding, but encoded independently from the surrounding object.

There is a close interaction between the linguistic-syntactic representation system and the affective representation system that appear in the mathematical process. On the other hand, since the mathematical conceptual system is fundamentally metaphoric, the analysis of the mathematical concept structure through linguistic representation can help to identify the source of cognitive and affective obstacles that interfere with mathematics learning. In this study, we analyzed the problem-solving protocols of mathematical gifted children from the perspective of cognitive language and meta-affect to identify the relationship between the functional characteristics of the text and metaphor they use and the functional characteristics of meta-affect. As a result, the behavior of the cognitive and affective characteristics of mathematically gifted children differed according to the success of problem solving. In the case of unsuccessful problem-solving, the use of metaphor as an internal representation system was relatively more frequent than in the successful case. In addition, while the cognitive linguistic aspects of metaphors play an important role in problem-solving, meta-affective attributes are closely related to the external representation of metaphors.

Purpose: This study examined the relationship between job stress, attributes of health functional food (HFF) selection, and consumption values for information technology (IT) workers, and analyzed the factors influencing the selection of HFF to improve health by making the right choice of HFFs. Methods: Three hundred forty IT workers in Gyeonggi area participated in the study. The participants were divided into low or high job stress group. The differences in participants' general characteristics, attributes of HFF selection, and HFF consumption values were investigated, and the mediating effects of HFF consumption values on the relationship between job stress levels and the HFF selection attributes were analyzed. Results: Job stress levels were high in those IT workers with a length of service < 5 years (p = 0.013). The group with lower job stress levels had a higher tendency to consider the ingredients contained in HFF products (p < 0.001), and their efficacy (p = 0.047). They also showed greater emotional value for a sense of security from consuming HFFs to stay healthy (p = 0.047). The group with higher job stress levels had greater epistemic value in that their choice of HFFs differentiated them from the other workers (p = 0.036). Higher job stress was associated with less consideration of the intrinsic attributes such as ingredients and efficacy of the HFF selection attributes (p = -0.113), emotional value of the HFF consumption values (p = -0.136), and the functional value such as practicality, price, and safety (p = -0.134). The job stress level influenced the intrinsic attributes through the functional and emotional values, demonstrating that the functional and emotional values had appropriate mediating effects on the relationship between job stress levels and intrinsic attributes. Conclusion: Education needs to be provided for workers to relieve job stress and improve the functional and emotional values, which contributes to choosing the appropriate HFFs.

As the marketing value of Facebook advertisements increases, companies seek to create successful Facebook advertisements in order to promote their brands or products. This research aims to identify Facebook advertising factors that influence users' eye movements and attention, and thereby to investigate effective visual elements of Facebook advertising contents. Firstly, we identified two contributing factors influencing users' responses to Facebook advertisements: the formats of advertising contents(Text, Text in Image, and Movie) and the product properties(Involvement, Think/Feel). Based on theoretical reviews, eye tracking tests and surveys were conducted in order to examine how these two factors affect users' responses on Facebook, i.e. visual perception and users' purchasing responses. It was found that there were distinctive patterns of users' visual perceptions and purchasing behavioral responses according to the formats of the advertised contents. Meanwhile, the advertised products' properties influenced only the users' purchasing responses. Finally, the key findings of this research offer helpful guidelines for providers and developers to create effective SNS advertisements.

Psychophysiologists are often interested in the EEG signals that accompany certain psychological events. When one is interested in a time series of event-related changes in EEG, one focuses on examining how the waveforms recorded at individual electrode sites vary over time across one or more experimental conditions. This is an analysis of event-related potentials (ERPs). In addition to such a classical EEG analysis in the time domain, the EEG measures can be investigated in the frequency domain. Moreover, it has been demonstrated that spectral analyses can often yield significant insight into the functional cognitive correlations of the signals. Therefore, this review paper tries to summarize essential concepts (e.g. phase-locking) and conventional methods (e.g. wavelet transformation) for understanding spectral analyses of brain oscillatory activity. Phase-coherence is also introduced in relation to functional connectivity of the brain.
