본 연구에서는 삼각함수의 모델링을 통한 그래픽 과정의 효과를 알아보기 위한 실험연구로 실험과정의 분석을 질적연구 방법으로 처리했다. 이를 위해 수학적 모델링의 절차를 세분하여 기존의 모델에 두 단계, 즉, 질문의 생성과 아이디어 교환을 강조하는 놀이실험단계와 컴퓨터 그래픽 과정의 단계를 추가했다. 실험은 고등학교 2학년을 대상으로 실험반(TMG) 26명이 참여했고, 데이터의 질적분석을 위해 활동지, 면담 및 실험과정의 관찰자료를 분석하였다. 국내외 대부분의 연구가 통계적 방법을 이용한 양적 분석 방법이기 때문에 교사들에게는 모델링 수업에 큰 도움을 주지 못한다. 연구결과로 (1) 기존의 수학적 모델링의 절차에 두 개의 단계를 추가하여 보다 세분화한 모델링의 과정은 질문생성, 아이디어교환, 동료들과 소통 등에서 긍정적인 결과를 볼 수 있었다. (2) 실험학교의 수학과 수업에 컴퓨터 그래픽을 포함한 테크놀로지의 도입은 양과 수(Quantity) 교육에 매우 적절함을 보여주었다.

The relevance of the research involves outlining the need for modern professionals to acquire new competencies. In the conditions of rapid civilizational progress, in order to meet the requirements of the labor market in the knowledge society, there is a readiness for continuous training as an indicator of professional success. The purpose of the research is to identify the impact of various forms of application of information technologies for lifelong learning in order to provide the continuous self-development of each person without cultural or age restrictions and on the basis of rapid digital progress. A high level (96%) of need of the adult population in continuing education with the use of digital technologies has been established. The most effective ways to implement the concept of "lifelong learning" have been identified (educational camps, lifelong learning, mass open online courses, Makerspace activities, portfolio use, use of emoji, casual game, scientific research with iVR game, implementation of digital games, work in scientific cafes). 2 basic objectives of continuing professional education for adults have been outlined (continuous improvement of qualifications and obtaining new qualifications). The features of ICT application in adult education have been investigated by using the following methods, namely: flexibility in terms of easy access to ideas, solving various problems, orientation approach, functional learning, group or individual learning, integration of leisure, personal and professional activities, gamification. The advantages of application of information technologies for continuous education (economic, time, and adaptive) have been revealed. The concept of continuous adult learning in the context of digitalization has been concluded. The research provides a description of the structural principles of the concept of additional education; a system of information requests of the applicant, as well as basic technologies for lifelong learning. The research indicates the lack of comprehensive research in the relevant field. The practical significance of the research results lies in the possibility of using the obtained results for a wider acquaintance of the adult population with the importance of the application of lifelong learning for professional activities and the introduction of methods for its implementation in the educational policy of the state.

최근 조사에서 30세 미만 게임 사용자들 간에는 그 수와 플레이 시간 등에서 성차가 거의 없다. 그러나 전투형 게임은 캐릭터의 설정 등에서 성 고정관념이 팽배하며 특히 여성 캐릭터의 성 도구화 문제가 대두되기도 했고 여성 게이머 관련 연구도 거의 없다. 본 논문은 여성 참여도가 높은 팀 기반 전투형 게임인 오버워치와 사이퍼즈의 여성 캐릭터에 대한 여성 게이머들의 선호도와 그 이유를 조사해 보았다. 총 231명이 응답한 오버워치 설문 조사에서는 성적 매력과는 거리가 있는 60대의 아나가 2위로, 걸 크러쉬형 캐릭터를 선호하는 캐릭터 인지 패턴이 나타났다. 반면 전사형 캐릭터가 없는 사이퍼즈의 경우에는 선호한 여성 캐릭터들은 외형적 매력이 영향을 미쳤는데 그 캐릭터들은 실제 플레이에는 제대로 사용되지 않음을 발견하였다. 즉, 외형적 매력은 캐릭터의 선호도는 높지만 수행 능력이 따라오지 않는다면 실제 게임에서 활용하지 않는다는 실리적 선택이 보이는데 이는 남성 게이머들과 차이가 없다.

The development and spread of IT-technologies has raised interest in teaching programming pupils. The article deals with problems related to programming and ways to overcome them. The importance of programming skills is emphasized, as this process promotes the formation of algorithmic thinking of pupils. The authors determined the level of pupils' interest to programing learning depending on the age. The analysis has showed that the natural interest of younger pupils in programming is decreasing over the years and in the most productive period of its study is minimized. It is revealed that senior school pupils are characterized by low level of interest in the study of programming; lack of motivation; the presence of psychological blocks on their own abilities in the context of programming; law level of computer science understanding. To overcome these problems, we conducted the second stage of the experiment, which was based on a change in the approach to programing learning, which involved pupils of non-specialized classes of senior school (experimental group). During the study of programming, special attention was paid to the motivational and psychological component, as well as the use of game technologies and teamwork of pupils. The results of the pedagogical experiment on studying the effectiveness of teaching programming for pupils of nonspecialized classes are presented. Improvement of the results provided the use of social and cognitive motives; application of verbal and non-verbal, external and internal means; communicative attacks; stimulation and psychological setting; game techniques, independent work and reflection, teamwork. The positive effect of the implemented methods is shown by the results verified by the methods of mathematical statistics in the experimental and control groups of pupils.

One of the most important technologies today is augmented reality technology, it allows users to experience the real world using virtual objects that are combined with the real world. This technology is interesting and has become applied in many sectors such as the shopping and medicine, also it has been included in the sector of education. In the field of education, AR technology has become widely used due to its effectiveness. It has many benefits, such as arousing students' interest in learning imaginative concepts that are difficult to understand. On the other hand, studies have proven that collaborative between students increases learning opportunities by exchanging information, and this is known as Collaborative Learning. The use of multimodal creates a distinctive and interesting experience, especially for students, as it increases the interaction of users with the technologies. The research aims at developing collaborative framework for developing achievement of 6th graders through designing a framework that integrated a collaborative framework with a multimodal input "hand-gesture and touch", considering the development of an effective, fun and easy to use framework with a multimodal interaction in AR technology that was applied to reformulate the genetics and traits lesson from the science textbook for the 6th grade, the first semester, the second lesson, in an interactive manner by creating a video based on the science teachers' consultations and a puzzle game in which the game images were inserted. As well, the framework adopted the cooperative between students to solve the questions. The finding showed a significant difference between post-test and pre-test of the experimental group on the mean scores of the science course at the level of remembering, understanding, and applying. Which indicates the success of the framework, in addition to the fact that 43 students preferred to use the framework over traditional education.

The purpose of this study is to unveil the characteristics of residential space organizations in dementia units. Observation, interview, and drawing analysis of the sample units were used to collect the data for new dementia unit plans. The findings revealed the lack of minimum requirement of residential spaces per person in some sample units, the necessity of consideration of group units, and the change of units based plans to each floor based plans. However, insufficient recreation rooms and the lack of caregivers' resting spaces in the sample units were uncovered. Thus, various recreation rooms such as a reading room, flower room, pottery room, bakery room, or game room should be provided in the sample units. The conclusion is that asylum oriented residential types should be changed to each floor based units having privacy and high satisfaction of residential life. The study of floor oriented residential units focusing on minimum spaces of the floor, space numbers, number of elderly persons on each floor should be studied in the near future.

This paper introduces a new motion-synthesis technique for animating multiple characters. At a high level, we introduce a hub-sub-control-point scheme that automatically generates many different spline curves from a user scribble. Then, each spline curve becomes a trajectory along which a 3D character moves. Based on the given curves, our algorithm synthesizes motions using a cyclic motion. In this process, space-time warp curves, which are time-warp curves, are embedded in the 3D environment to control the speed of the motions. Since the space-time warp curve represents a trajectory over the time domain, it enables us to verify whether the trajectory causes any collisions between characters by simply checking whether two space-time warp curves intersect. In addition, it is possible to edit space-time warp curves at run time to change the speed of the characters. We use several experiments to demonstrate that the proposed algorithm can efficiently synthesize a group of character motions. Our method creates collision-avoiding trajectories ten times faster than those created manually.

A reader usually spends a lot of time browsing and searching word meaning in a dictionary, internet or smart applications in order to find the unknown words. In this paper, we propose a method to compensate this drawback. The proposed method introduces a vocabulary upon recognizing a word or group of words that was captured by a smart phone camera. Through this proposed method, organizing and editing words that were captured by smart phone, searching the dictionary data using bisection method, listening pronunciation with the use of speech synthesizer, building and editing of vocabulary stored in database are given as the features. A smart phone application for organizing English words was established. The proposed method significantly reduces the organizing time for unknown English words and increases the English learning efficiency.
