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.

Based on the theory of interactive experience in children's toy design, this paper analyzes and explores the interactive experience of education children's toys. Based on the basic elements of product design, a case study of the popular children's educational toys in the Korean sales rankings was carried out. In addition, according to the user experience model, a questionnaire survey was conducted on the popular children's educational toys sold in Korea. The results show that the top three children's educational toys by sales are smart toys. Satisfaction is highest for feeling, feeling, thinking, acting, and related experiences. It provides a theoretical basis for the interactive experience design of children's smart toys. Design experiential toys that are more suitable for children's physical and mental health and more suitable for children's psychological development.

This study aimed to investigate the epidemiology of canine ophthalmic diseases in Seoul, Korea using data for new canine patients examined from January 2009 through December 2013 at an ophthalmic referral center (WooSung Animal Medical Center, Seoul). The study included 1253 dogs with an average age of 7.93 years (SD, 4.06). Shih Tzu (29.4%) was the most common breed, followed by Maltese, Yorkshire Terrier, Cocker Spaniel, and toy Poodle (P < 0.01). Lens diseases (28.3%) were the most common, followed by eyelid, corneal, retinal, and glaucomatous diseases (P < 0.01). Lens, eyelid, retinal, nasolacrimal, uveal, vitreous, and neuro-ophthalmic diseases more frequently showed a bilateral occurrence (P < 0.01) than a unilateral occurrence. In the Shih Tzu breed, corneal disease was the most frequent, followed by lens, eyelid, retinal, and glaucomatous diseases. The most frequent diseases in the Maltese breed were lens, eyelid, retinal, and corneal diseases. In the Yorkshire Terrier, Cocker Spaniel, and toy Poodle breeds, lens disease was the most common (P < 0.01). The most frequent ophthalmic patients belonged to small breeds such as Shih Tzu, Maltese, and Yorkshire Terrier. Moreover, the most common ophthalmic diseases were not traumatic diseases, but breed-inherited diseases such as lens diseases.

The recent domestic toy market is filled with the fever of 'Turning Mecard' produced as a character product of units showing in . The toy market of the domestic character licensing industry has shown such rapidly changing trends during the period of broadcasting contents like animation or special films targeting children. Through these contents, the characters are cognized, and also the immersion and loyalty can be increased depending on the progress of the story, on top of marketing effect while the animation is broadcasted. This effect is called gamification meaning that consumers voluntarily participate in the contents after receiving fun. Through the purchase of character products, the immersion and loyalty participate in the animation. Thus, this study analyzed the gamification elements by examining the animation and toy products of currently gaining popularity in the toy market. In the results of the study, the story structure of has the sustainment just like game, which is connected to its character product. Therefore, the users who have watched build up the relationship with each other, and the competition and reward can be done through the game using the character products, which is connected to such high immersion and loyalty.

A heuristic method TABU-CSP using Tabu Search (TS) is described for solving Constraint Satisfaction Problems (CSPs). The method is started with a complete but inconsistent solution of a binary CSP and obtained in prespecified number of iterations either a consistent solution or a near optimal solution with an acceptable number of conflicts. The repair in the solution at each iterative step is done by using two heuristics alternatively. The first heuristic is a min-conflicts heuristic that chooses a variable with the maximum number of conflicts and reassigns it the value which leads to the minimum number of conflicts. If the acceptable solution is not reached after the search continued for a certain number of iterations, the min-conflict heuristic is changed and the variable selected least number of times is chosen for repair. If an acceptable solution is not reached, the method switches back to the min-conflict heuristic and proceeds further. This allowed the method to explore a different region of search space space for the solution as well as to prevent cycling. The demonstration of the method is shown on a toy problem [9]which has no solution. The method is then tested on various randomly generated CSPs with different starting solutions. The performance of the proposed method in terms of the average number of consistency is checked and the average number of conflicts is conflicts is compared with that of the Branch and Bound(BB) method used to obtain the same solution. In almost all cases, the proposed method moves faster to the acceptable solution than BB.

This article deals with the manufacture and test results of asbestos-free friction material for Aluminium at toy disk. In order to obtain optimum formulation, various formulations of fibres, matrix, modifiers, fillers, etc were designed and evaluated. The constant friction and brake dynamometer tests were performed to know weak and strong point for each friction material. The C21 formulation of various tested formulations exhibited superior friction constant(0.38∼38), fade rate (18%) by JASO C406 test mode and maximum wear 1.6 mm. disc wear 0.08 mm by JASO C427 test mode. The surface morphology of AL alloy disk(before and after test) was observed by Scanning Electron Microscope(SEM) and Image Analyzer.
