최근 소프트웨어의 중요성이 증가함에 따라 국내에서도 초등학교에서 소프트웨어 교육이 의무화되고 있다. 이러한 시점에서 스마트토이를 이용하여 놀이와 교육을 접목한 코딩 교육이 이루어지고 있다. 다양한 스마트토이 중 가장 널리 이용되고 있는 스마트 토이 중 하나는 블록형 스마트 토이이다. 본 연구에서는 블록형 스마트토이를 조작할 수 있는 스마트폰 애플리케이션에 대한 사용자의 사용성을 향상시키기 위한 평가를 실시하였다. 이를 위해 다양한 사용성 평가 기법 중 하나인 전문가를 대상으로 한 휴리스틱 기법을 실시하였다. 분석 결과, 메뉴의 버튼과 스위치 구분이 잘 이루어지지 않았으며, 오류 발생 시 발생 원인이 사용자에게 제공되지 않는 것으로 나타났다. 본 연구 결과는 향후 스마트토이를 위한 애플리케이션의 사용성을 향상시키는데 기반이 될 수 있다.

Recent reports studied that injuries or deaths frequently occurred in consumer product accidents by product defects. Broadly speaking, product liability is liability which is imposed upon a manufacturer or other seller for personal injury, death, property damage and/or commercial loss arising with respect to a product or service provided by it. In this study, we want to search a method of prevention against appling PL laws. The way was researching on the level of appreciation of PL law, warning messages's means and design criteria for seller or consumer of child toys. As a result, most people didn't understand PL laws. Although they read them before purchasing child toy, many consumers didn't differentiate means of "Notice", "Warning", and "Danger" in warning messages. In addition, they considered important factors in warning messages as notice warning, safety mark(UL, etc), age recommendation and color in order. This study will be effective to search a method of prevention against PL laws.

음성인식은 여러 분야에 적용될 수 있지만 지능형 장난감에 적용된 사례를 보면 다른 시스템에서 적용된 경우와 같이 높은 인식률이 요구된다. 하지만 음성인식의 기능만으로 지능형 장난감의 기능이 다양성을 가지지 못한다. 음성인식기능 뿐만 아니라 다른 여러 가지의 기능을 가진 지능형 장난감의 소프트웨어를 개발하는 것이 다른 시스템과의 차별성을 두는 것이 된다. 본 논문에서는 이 Intelligent Toy에 내장될 음성인식 등의 여러 가지의 기능을 가진 Software를 구현하는 방법 및 결과를 제시한다. 대표적 기능인 음성인식은 화자종속이고 그 인식률은 99%의 높은 인식률을 얻었다. 그외에도 음성합성, 음악합성, 음성녹음 및 재생 등의 기능구현을 하였다. 음성인식을 가진 Intelligent Toy 계열의 시스템과 같은 잡음 환경 하에서 인식률을 비교해 볼 때 그 결과가 우수함을 확인하였다.

Wood material is positive with the concept of eco-friendly materials. Wood toy preference of foreign brands is also a real problem. Therefore, in this domestic situation on Toys Brand Development, there are many problems yet to be solved. At First, a wood material for toys requires the development of more sophisticated and precision materials. Second, new content, product development and training program development of the toys are needed. Characters and content development time and effort should be invested. In present, Korean brand development of wood toy with educational effects is very important issues as the use of wood to match the low carbon & green growth.

Objectives: This study was to examine the effectiveness of computerized cognitive ability enhancement program (CCAEP) using Smarttoy. The CCAEP using Smart-toy which can interact with children via bluetooth is a kids-friendly and convenient method for improving children's cognitive abilities by increasing their motivation for performing the program. We developed the CCAEP which designed to train auditory-verbal memory, visual-spatial memory, auditory-verbal working memory, and visual-spatial working memory. Methods: Eighteen children aged 8 to 10 participated in CCAEP individual training composed of 8 sessions of 40 minutes each for 4 weeks. The effect of the training was measured with Smart Toyweb's cognitive assessment tasks (smart device based assessment) as well as traditional neuropsychological tests before and after the training. Results: Children showed significant improvement in auditory-verbal memory, visual-spatial memory, auditory-verbal working memory and visual-spatial working memory abilities after the training. Conclusion: This study demonstrated promising results suggesting the effectiveness of CCAEP using Smart-Toy in clinical settings as well as school and home situations. Further controlled study with larger sample size including various clinical groups is needed to confirm the present results.

오픈소스가 소프트웨어의 영역을 넘어 그 개념이 여러 분야로 확장되어감에 따라 여러 기업들이 오픈소스 개념을 이용한 비즈니스 모델을 등장시키고 있다. 본 연구는 3D프린터를 활용한 웹 기반 오픈소스 플랫폼 제작 방안에 관한 연구로서 키덜트 문화를 접목시킨 사용자의 자발적 참여도가 높은 오픈소스 플랫폼 커뮤니티 제작을 목표로 한다. 연구방법으로는 여러 기업의 오픈소스 활용 사례에 관한 분석 연구와 더불어 키덜트 커뮤니티의 사용자 설문을 통해 플랫폼의 사용성과 토이 디자인 선호도 및 성향 분석을 기반으로 한 기초 자료 수집을 통하여 초기 플랫폼 제작 방향성을 설정하였다. 제작된 플랫폼에서 고유의 플랫폼 토이 소스를 다운로드 후 사용자가 자유롭게 재해석하고 플랫폼에 결과물을 재공유하여 완성된 디자인의 선호도에 따라 판매하여 수익을 분배할 수 있도록 하는 것이 특징이다. 향후 플랫폼 내 커뮤니티를 활성화하여 사용자의 진입동기부여를 높이는 연구가 지속하여야 할 것이다.

Many impact or drop test researches of home appliances are published, but those of toys cannot be found easily. External impacts are the primary causes of fracture of toys. For impact proof design, the finished product should pass an impact test after molding design. There are several international toy safety standards or requirements such as US CPSC(Consumer Product Safety Commission), ASTM F963-96a, EN71 and so on. The puppy robot which patrols around the house, namely, the watchdog was selected to investigate toy safety because it has considerable weight and outer panels are made of plastics. First the model of watchdog robot was obtained by 3 dimensional scan. Surface data can be generated from 3D polygon data of the watchdog. A reliable drop simulation method for the watchdog was established using Pam-crash program according to Korean toy safety standards. When there is a low impact allowance value, the molding design should be reinforced or changed. It was found that the maximum impact stress reaches the ultimate stress of panel material.

The aim of the present study was to investigate the relations between wooden toy and development of infant and young children by taking only the commercialized wooden furniture which would be suitable for the developmental area for infant and young children, among the physical environment influencing the balanced development and development for them. The recommended standard for them was the commercialized good and the only advanced toys for the development of infant and young children was primary selected, in case of different furniture for same purpose with regardless of manufacturer, country of origin and price. The selected wooden toys for development of infant and young children covered the following test conditions. They keep the soft and clean surfaces and the corners are the round-finished so safe. The dyeing and coloring are so clear like the rainbow-colored in compliance with the international safety norm, and the paint material used are harmless to the people, because they have already passed the European Safety Norm EN 71 which is the most authoritative and strict standard in the world and contained accordingly little heavy metals, toxic substances and also allergy pigment under the maximum permissible standard. The size of wooden toys are not small enough for infant and young children to be able to swallow and this is important check point, because infants tend to feel the object in their own touching and therefore to have everything to the lip. The paint used was the toys-oriented goods and proved by the test regarding saliva and sweat.
