스마트 토이(Smart Toy)란 인공지능이나 사물인터넷과 같은 차세대 정보통신기술이 접목된 장난감을 의미한다. 장난감의 고유 특성상 사용자의 만족감을 부여하는 목적만을 전부로 하지만, 스마트 토이의 기능들을 활용하여 사용자로부터 흥미도 및 이용 측면 등의 데이터를 수집할 수 있다면, 사용자의 만족감 및 발달 정보 등의 부가 효과들을 기대할 수 있다. 이에 본 연구에서는 스마트 토이를 활용한 사용자의 데이터 수집을 위한 인터페이스를 설계하고, 그 내용을 기술한다.

This paper will describe the design of database for system engineering of High Speed Railway Systems, focusing on tile ability to capture a full thread of traceability, from tile inception of a system requirement, to the test results that validate that the designed system meets criteria defined by the requirement. The database includes data models for requirement, function, component, work, work process, resource, etc.. These data models are utilized for tile efficient management of data related system design, development work, and validation.

This study tried to analyze $CO_2$ emission volume as green-house gases by application of land use patterns and transport policies in District Unit Design. It is postulated a Toy network and various scenarios which are combined land use patterns and transport policies for analyzing $CO_2$ gas reduction. As results, this study shows best District Unit Design technique is the policy that develop mid block and introduction of car free zone to inner 2 way streets. Worst design technique is the policy that make hierarchical network and introduction of access control to outer roads that have been known as a best road policy till nowadays. Therefore, we need more carefully introduce design technique for reduction of $CO_2$ in District Unit.

In order to realize the operation of the creative modular toy, it is required to record the motion and to read and repeat the motion. At this time, a control potentiometer is used to read the absolute angle of rotation of the toy motion output shaft. However, the unstable part of the sensing area of the potentiometer is present in a certain region, which may lead to instability of the motor control. In this paper, we propose an algorithm to find the absolute angle of one rotation by reading two stable potentiometers on one axis and reading each stable region. We also describe the correction algorithm that is needed to perform multiple rotations. The proposed method is applied to Topobo modular toys to record the operation and perform iterative operation. In addition, multi-turn operation is recorded and operated to suggest the usefulness of the proposed method. In the future, we will expand the functions of recording and playback through various actions.

Modern society has a tendency to raise fewer children. As a result, parents became more interested in their children's creative ways of thinking and began to look for new ways of teaching. The child care support center expects a positive effect by lending various toys and books to improve the physical, emotional and social characteristics of children and to help reduce household burden on parents. In this paper, we design and implement a rental return system to effectively utilize a toy library operated by the child care support center. The proposed system makes it easy for any user to search for items in any branch operated by the Child Care Support Center and to manage loan return records. The administrator can manage data such as loans, returns, and past due from the rental return processing system, and effectively operate the child care support center through statistics of data generated. Children are expected to be given a variety of entertainment cultures and cultural benefits to their families to ease the burden of parenting.

The center of rotation of angulation-based leveling osteotomy (CBLO) has been introduced for the stabilization of cranial cruciate ligament rupture (CCLR) in small-breed dogs. This technique can be applied to the tibia without damaging its tuberosity. Although different designs of CBLO plates are available, tibial plateau leveling osteotomy (TPLO) plates have been still used for stabilization during CBLO. To the best of our knowledge, no studies have reported the effects of TPLO plates on the postoperative limb alignment after CBLO. Therefore, the present study (January 2020 to February 2021) aimed to compare the postoperative outcomes (postoperative tibial plateau angle [TPA] and tibial alignment) in patients receiving CBLO and TPLO plates during CBLO. Paired stifle joints (n = 16) were obtained from eight toy-breed cadaver dogs (mean weight, 4.4 kg) that underwent CBLO. The joints were randomly assigned to receive the CBLO (CBLO group) or TPLO plates (TPLO group). Pre-and postoperative radiographs were obtained, and the dissected tibiae were evaluated. The following postoperative parameters were compared to evaluate the surgical outcome: TPA, osteotomy location, mechanical medial proximal tibia angle, inter-segment gap, and tibial plateau translation. No significant differences were found in the postoperative alignment between the two groups. Therefore, TPLO plates may be considered as a viable alternative in toy-breed dogs undergoing CBLO.

Strength test using strain rosette gage have been conducted to investigate safety of an auxiliary tank in a high-pressure air compressor. Thickness of auxiliary tanks in 6063-T5 aluminum at toy are 9mm and 17mm. The result of strength test make a comparison the design in strength of materials by nominal stress and the design in fracture mechanics with consideration of crack size. Summarizing the result: Comparing with the safe working pressure of the strength test and that of the design method in strength of materials by nominal stress with the experimental values, it makes difference 11% and 39% for 9mm and 17mm thickness of auxiliary tanks, respectively, and that of the design method by fracture mechanics, it makes difference 4％ and 5% for them, respectively. It is confirmed that the design by fracture mechanics is more economical and safe design than the design in strength of materials by nominal stress.

This study is about the cases in fashion figure appearing the contemporary fashion and their characteristics. The work aims at providing a further active research opportunity for fashion figure in the modern fashion field and finding several possible utilizations to help the overall fashion industry through examination. Research methodology was followed up with the related literature review and empirical work through the case study of multiple fashion figures denoted in the contemporary fashion. The results showed in the following way for types of fashion figure in the modern fashion. The first type is that its figure was used for stage apparatus in fashion collection, various properties, or garment tool as doll shifted to a certain object. The second type is that art toy or fashion doll was used as specially added product via way of cooperation with fashion brand to be applied as fashion figure alone or other properties for T-shirt or something like that. The third type is the case that multifariously sized figures were applied to show window or shop display. This type of fashion figure is basically an imbedded fashionistic feature, reflecting the rarity, publicity, playfulness, and artistic value.

The human species has been able to fly for about a century - with the help of aircraft of various kinds. Recently. air vehicles which are like an insect or a bird with flapping wings have been appeared, although many of them are experimental flight vehicle. However, the rubber-powered flapping vehicle is put to practical use such as toy, which flies for some seconds. In this paper, we analyze and evaluate above the rubber-powered flight vehicle using axiomatic design and will present new four flapping wing model.
