가을철은 기온이 선선해지면서 사람들의 활동량이 늘어나는 계절이다. 어린이들도 학교나 가정 등, 실내외 활동이 왕성해지면서 각종 안전사고에 노출되기 쉬워진다. 특히 어린이들은 주변 사물에 대한 호기심이 크고 활동량이 많은 특징을 가지고 있으나 주의력과 판단력 등 인지능력이 아직 성숙하지 못한 까닭에 위험에 대처하는 능력이 미숙하다. 띠라서 상시 안전사고 예방교육을 통해 어린이들에게 위험요소들에 대한 주의와 대처 능력을 키워주어야 한다. 어린이들의 활동량이 늘어나는 계절 10월, 이번호에서는 어린이 안전사고 예방 교육의 중요성과 각종 안전사고 사례, 예방과 응급처치 등에 대한 특집을 마련한다.

For efficient quantization of speech representation, it is common to incorporate Perceptual characteristics of human hearing. However, the focus has been confined only to the magnitude information of speech, and little attention has been paid to phase information. This paper presents a novel approach, termed perceptually irrelevant phase elimination (PIPE), to find out irrelevant phase information of acoustic signals in terms of perception. The proposed method, which is based on the observation that the relative phase relationship within a critical band is perceptually important, is derived not only for stationary Fourier signal but also for harmonic signal. The proposed method is incorporated into the analysis/synthesis system based on harmonic representation of speech, and subjective test results demonstrate the effectiveness of proposed method.

The purpose of this study was to analyze the effects of digital literacy and the frequency of contact with children or grandchildren via ICT on cognitive functions of 8,942 adults over age 65 who responded to the 2017 National Survey of Older Koreans, using multiple regression analysis. We found that digital literacy was the most significant factor on cognitive functions of the elderly. Also, the frequency of contact with grandchildren via ICT was a positive factor for cognitive function and had a positive correlation with digital literacy. Based on this results, the importance of digital literacy education and intergenerational communication via ICT were discussed.

Purpose: This study was carried out to suggest methods for improving school health promotion programs by investigating the daily activities and the performance level of environment management, the awareness of importance, and opinions on the revision of and knowledge about laws and regulations related to school health promotion programs. Method: The subjects of this study were 289 school nurses in Gyeongsangbuk-do. The survey used a questionnaire containing 90 questions developed by the present researcher. Data were collected from July 5 to July 21, 2006 and analyzed using SPSS 12.0 for Windows. Result: 1. Regular check-up and drinking water management got the highest score in performance level. Sexual health and drinking water management got the highest score in the awareness of importance. 2. School nurses were aware of laws and regulations related to their clients (0.93), and the revision opinion was high on the whole (3.58). 3. According to general characteristics, the more educated school nurse were (F=6.80, p=.001) and the fewer students their school had (F=4.66, p=.010), the higher their performance level in daily activities was. The shorter their career in their work was (F=4.86, p=.008), the fewer classes their school had (F=5.04, p=.007) and the fewer students their school had (F=3.83, p=.023), the higher their awareness of importance was. 4. There was not any difference in the performance level of environment management according to general characteristics. The awareness of importance was highest in school nurses with experience less then ten years (F=3.66, p=.027). 5. There was not any difference in knowledge about laws and regulations according to general characteristics. The revision opinion was high in school nurses at schools with less than 18 classrooms (F=6.04, p=.003) and less than 500 students (F=4.24, p=.015). Conclusion: When school nurses perform school health promotion programs actively and vigorously, the students can be healthy and national health promotion can be actualized fundamentally.

As the game industry is steadily becoming the spotlight industry, the importance of user experience design in game industry is increasing. This study tried to approach game from the viewpoint of user experience design and aimed to analyze the onboarding process focusing on user accessibility and retention in an online game. First, through literature review, onboarding process was devided into three stages. Then each stages were analyzed into experience design, game design elements to derive the key UX factors. Second, based on the UX elements, the game experience and cognitive element analysis frame was presented. With this frame, five domestic online games were qualitatively analyzed and cognitive elements of each game's onboarding process were derived. Key cognitive factors in each stages were, selective attention in the discovery stage, working memory and active learning in the learning stage, and participation and motivation in the immersion stage. Finally, improvement direction were presented, focusing on the key cognitive factors. These studies highlight the importance of the user entry process in online games and suggests improvements to lower entry barriers.

In spite of the importance of cognitive conflict in conceptual change, there has been little research on the characteristics of cognitive conflict in students enrolled at vocational high schools. The purpose of this study was to expose these students' cognitive conflict types and investigate characteristics of cognitive conflict according to the type of cognitive conflict. This paper examined how vocational students' motivational beliefs and epistemological beliefs affect the process of cognitive conflict when students are confronted with an anomalous situation related to the action and reaction concept. Results indicated that many vocational students experienced low levels of cognitive conflict and remained passive during the explanation of anomalous phenomenon or easily desisted any attempt to resolve the conflict situation because of their epistemological belief to depend on the external absolute knowledge of teachers, an extrinsic motivation to choose easier tasks, or reliance on the teachers' reputations. Therefore, Instructors need to recognize these characteristics in order to facilitate vocational students' conceptual change when presenting cognitive conflict tasks.

The performance of navigational equipments is advanced, but the importance of the practical capability of bridge device by ship's officer, ie the ability of risk prediction and the obligation of avoidance for reducing sea accident, has been constantly augmenting. This abilities and obligation may be represented in the cognitive competence of navigational officer. Different levels of ship's bridge team was carried out rescue maneuvering by ship handling simulator and then it analyzed the resulting of initial response in cognitive progress by case based on trajectory. Further, the data will be used as training and evaluation model of cognitive situation.

인간의 능력은 유전과 환경에 의해 결정되며, 정보는 인지와 감성의 긴밀한 상호작용을 통하여 처리된다. 이런 관점에서 보면, 정보처리모델에서는 유전과 환경, 인지와 감성 작용이 모두 고려되어야 한다. 본 논문에서는 감성이론과 정보처리모델을 바탕으로 감성필터모델을 제시하였다. 이 모델에서는 감성필터가 입력을 선별적으로 수용하며, 수용된 입력은 자신의 현재 능력과 함께 상호작용을 하며 정보를 처리하게 된다. 정보를 처리하는 과정에서 인간은 지식과 경험을 재구성하거나 잠재력을 계발할 수 있다. 이 모델을 통하여, 새로운 관전에서 유전과 환경의 의미 그리고 감성과 인지의 역할을 살펴보았다. 또한 교육적인 관점에서 감성교육과 감성공학의 의미에 대하여 살펴보았다.

본 연구는 과학영재교육의 중요성이 증대되고 있는 현 시점에서 이의 효과적인 성취를 가져오기 위해선 우선 영재 판별의 시도가 다양해져야 한다는 필요성에서 출발하였다. 그 동안 영재 판별은 주로 인지수행의 결과적인 측면을 다루었다고 본다면, 본 연구는 인지수행의 과정적인 측면을 다루었다고 할 수 있다. 인지수행의 과정적인 측면은 뇌기능의 활동성을 파악하는 것으로 가능하다. 따라서 뇌의 활동성에 대한 뇌파측정 방법을 통해 좌.우뇌 기능상에서의 뇌파특성을 파악해 보므로써 영재성 판별의 한 방법으로서 그 가능성의 단초를 제공하는데 본 연구의 주목적이 있다. 이를 위해 영재성 판별 및 뇌기능 연구방법과 뇌의 정보처리과정에 대한 이론적인 고찰을 바탕으로 초등학교 4-6학년 아동 중 과학영재아 11명, 일반아 10을 연구대상으로 선정하여 PC용 뇌파측정기를 통해 이들의 뇌파특성을 분석한 결과, 다음과 같이 나타났다. 다음 표는 과학영재아 및 일반아의 아무런 과제를 수행하지 않은 상태의 기본뇌파와 과학 창의적 과제를 수행중인 상태에서의 뇌파를 좌뇌와 우뇌의 뇌파 활성도별로 그 차이를 분석한 것이다.

Aesthetics undertakes important roll in design as a competitive factor. The importance of aesthetics can be found in experimental aesthetics, Gestalt psychology and design related literatures. These literatures suggest that, besides the importance of aesthetics, many other aesthetic factors would affect consumer reaction(recognition, emotional reaction, meaning), but the study is still in insufficient condition. Hense, this study tries to give a guideline -'how to design symbols'based on the apprehension of what kind of design is well recognized(correct recognition), gives positive emotional reaction(affect) to customers, and moreover, what sort of aesthetic factors affect these reactions by analyzing existing symbol designs.
