This paper introduces a scheme for optimizing the material properties of mass-spring systems of different resolutions to provide coherent behavior for reduced level-of-detail in MSS(Mass-Spring System) meshes. The global optimal material coefficients are derived to match the behavior of provided reference mesh. The proposed method also gives us insight into levels of reduction that we can achieve in the systematic behavioral coherency among the different resolution of MSS meshes. We obtain visually acceptable coherent behaviors for cloth models based on our proposed error metric and identify that this method can significantly reduce the resolution levels of simulated objects. In addition, we have confirmed coherent behaviors with different resolutions through various experimental validation tests. We analyzed spring force estimations through triangular Barycentric coordinates based from the reference MSS that uses a Gaussian kernel based distribution. Experimental results show that the displacement difference ratio of the node positions is less than 10% even if the number of nodes of $MSS^{sim}$ decreases by more than 50% compared with $MSS^{ref}$. Therefore, we believe that it can be applied to various fields that are requiring the real-time simulation technology such as VR, AR, surgical simulation, mobile game, and numerous other application domains.

According to the Ministry of Health and Welfare, "Status of Registered Persons with Disabilities", the number of people with disabilities is 2,494,460 as of 2015. The lowest rates of children with disabilities were intellectual disabilities (23%) and mental disorders (33.3%). The highest rates of screening were blindness (97%), heart failure (94.4%), and hearing impairment (92.7%). 65.2% of visually impaired people who have already had a disability at the time of marriage, and the remaining 34.8% can be thought to be the cause of high incidence of disability after marriage. 'SID (Seed in the Dark)' project was designed to recapture the visually impaired parent's desire for attachment and the space difficulties of the blind who want to be a normal parent to their children through a visual impairment of a father with 7-year-old daughter. Using Gear VR(Virtual Reality), the general public was able to feel the surroundings as if they had no vision and focused on the hearing. Especially, We expressed the sound wave visually and added the hilarious game element which grasps the terrain of the maze by sound wave like a 'blind person who perceives the surroundings by sound' and catches up with daughter. People with disabilities who are far from mental illness often have a form of family with children. The fact that the rate of childbirth is high means that there is relatively little problem in daily life. It is wondered that the rate of blindness among the visually impaired, which accounts for 10% of the total disabled, is the highest at 97%. This is because, in the case of the visually impaired, the obstacle is often caused by aging, accidents, or diseases due to inherited causes rather than the visual disorder. In particular, However, the fact that there is an obstacle in vision that accounts for 83% of the body's sensory organs causes other difficulties in the nursing process of children who are non-disabled. Parents do not know the face of child when their visual impairment is severe. Parents are extremely anxious about worry that they will be lost or abducted if their children are not by their side. And that the child recognizes the disability of his or her parents other than the other parents easily and takes it as a deficiency. Since visually impaired parents are mentally mature parents with non-disabled people, they may want their children not to feel deprived of their disability. The number of people with visual impairments has been increasing since 2001, and people with impairments often become disabled. In addition, there is much research on the problem of nondisabled parents who have children with disabilities, while there is relatively little interest and research on the problem of nondisabled child rearing of parents with disabilities.

본 연구의 자료처리는 텍스톰(textom)과 소셜미디어의 단어를 중심으로 3가지 영역인 '코로나 19와 프로야구', '코로나 19와 프로야구 무관중', '코로나 19와 프로스포츠'에 대해 웹 환경에서 데이터 수집과 정제작업을 실시한 후 일괄 처리하였으며, 이를 시각화하기 위해 Ucinet6프로그램을 활용하였다. 구체적으로 웹 환경의 수집은 네이버, 다음, 구글의 채널을 활용하였고, 추출된 단어들 중 전문가회의를 통해 30개의 단어로 요약 정리하여 최종 연구에 활용하였다. 30개의 추출된 단어를 매트릭스를 통해 시각화하였으며, 단어의 유사성과 공통성의 군집을 파악하기 위해 CONCOR분석을 실시하였다. 분석결과 코로나 19와 프로야구에 관련된 군집은 1개의 중심클러스터와 5개의 주변클러스터로 구성되었고 코로나 19여파에 따른 프로야구 개막과 관련된 내용을 주로 검색하고 있는 것으로 나타났다. 코로나 19와 프로야구 무관중에 관련된 군집은 1개의 중심 클러스터와 5개의 주변클러스터로 구성되었으며, 코로나 19에 따른 프로야구 경기와 관련된 프로야구 입장의 키워드를 주로 검색하고 있는 것으로 나타났다. 코로나 19와 프로스포츠에 관련된 군집은 1개의 중심클러스터와 5개의 주변클러스터로 구성되었으며, 코로나 19의 여파에 따른 프로스포츠 시작과 관련된 키워드를 주로 검색하고 있는 것으로 나타났다. 이를 종합해보면 포스트 코로나 시대의 프로야구는 많은 변화가 있을 것이라 예상된다. 특히 응원문화는 관중들이 원하는 정도의 만족감은 없겠지만 관중들이 누릴 수 있는 직접관람의 기회를 누리기 위해 야구장에서도 코로나 19를 극복하기 위한 하나의 일상으로의 행동강령이 잘 유지되어야 할 것이다. 관람문화 또한 라이브커머스, AR/VR, O4O(Online for Offline)등의 4차 산업혁명의 기술도입으로 현장감 있는 쌍방향 소통이 가능한 인터렉티브 소통의 디지털이 구현돼야 할 것이다. 포스트 코로나 시대는 프로스포츠에도 새로운 형태의 패러다임이 구축될 것이다. 랜선 응원, SNS를 활용한 응원, 실시간 동시시청, 라이브 채팅응원, 편파중계 등 다양한 형태의 응원문화가 새로운 창작 콘텐츠 형태로 진화할 것이며, 팬들의 욕구를 충족할 수 있는 새로운 형태의 패러다임이 구축돼야 하겠다.
