With the recent increase in the importance of software, software education is required in elementary schools in Korea. At this point, coding education combining play and education using smart toys is widely used. One of the most widely used smart toys is a block type smart toy. In this study, usability evaluation was performed to improve user's usability for block type smart toy with smartphone application. In order to achieve the purpose of this study, a heuristic technique with experts, one of various usability evaluation techniques, was performed. As a result of the analysis, it was found that the buttons and the switch of the menu were not well distinguished, and the cause of the error was not provided to the user. The results of this study can be the basis for improving the usability of applications for smart toy in the future.

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.

As the concept of open source extends beyond the scope of software, many companies are also introducing business models using open source concepts. This study is a study on how to create a web-based open-source platform using a 3D printer and aims to create an open-source platform modeled on the Kidults community where users are highly willing to participate. The research method established the direction of initial platform production by collecting basic data through the usability of the platform and Toy design preferences and propensity analysis through research on open source use cases by various companies and user surveys in the Kidults Community. Features unique platform Toy sources that are freely reinterpreted by the user and re-shared and sold to the platform. Research should continue to boost user motivation by activating communities within the platform.

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.
