MPEG (Moving Picture Experts Group) - I (Immersive) is the standard for constructing an ecosystem based on immersivemedia. This paper explores the status of patent applications, published patent applications, and granted patents related to MPEG-I'sV-PCC (Video-based Point Cloud Coding), MIV (MPEG Immersive Video), G-PCC (Geometry-based Point Cloud Coding), andOMAF (Omnidirectional Media Application Format) standards, utilizing data from the world's top 5 patent offices known as IP5. This analysis can be used to identify data trends and understand technological maturity. Based on the results of patent analysis,strategies can be developed to enhance technological competitiveness in field of immersive video.

MicroRNA-146a Suppresses Metastatic Activity in Brain Metastasis
황수진,김현호,Ho Jun Seol,박영미,Kang Ho Kim,Myriam Gorospe,남도현 한국분자세포생물학회 2012 Molecules and cells Vol.34 No.3
Primary lung tumors, breast tumors, and melanoma me-tastasize mainly in the brain where therapy is limited to surgery and radiation. To investigate the molecular basis of brain metastases, we isolated brain-trophic metastatic MDA-MB-435-LvBr2 (LvBr2) cells via left ventricle (LV) injection of MDA-MB-435 cells into immunodeficiency (NOD/ SCID) mice. Whereas parent MDA-MB-435 cells displayed an elongated morphology, LvBr2 cells were round and displayed an aggregated distribution. LvBr2 cells expressed lower beta-catenin levels and higher heterogeneous nuclear ribonucleoprotein C1/C2 (hnRNPC) levels than parental cells. Since microRNAs are known to play an important role in cancer progression including metastasis, we screened microRNAs expressed specifically in brain metastases. MicroRNA-146a was almost undetectable in LvBr2 cells and highly expressed in the parental cells. Overexpression of miR-146a increased beta-catenin expression and suppressed the migratory and invasive activity of LvBr2 cells. The miR-146a-elicited decrease in hnRNPC in turn lowered the expression of MMP-1, uPA, and uPAR and inhibited the migratory and invasive activity of LvBr2 cells. Taken together, our findings indicate that miR-146a is virtually absent from brain metastases and can suppress their metastatic potential including their migratory and invasive activities associated with upregulation of beta-catenin and downregulation of hnRNPC.

황수진 물리치료재활과학회 2018 Physical therapy rehabilitation science Vol.7 No.3
Objective: Older persons with diabetes mellitus (DM) are particularly more likely to have fallen in the previous year than those without DM. The purpose of this study was to investigate the relationship between the risk of falls and type 2 DM in older adults who are 65 years of age or above. Design: A systematic review. Methods: PubMed and other two databases were searched up to August 2, 2018. Observational and cohort studies evaluating fall risk in people who are 65 years of age or above with DM were included. This review extracted the following information from each study selected: first author’s surname, year of publication, country, average follow-up period, sex, age at enrollment, study population, measurement variables, relative risk, 95% confidence intervals and controlled variables. Results: This review involved nine cohort studies with 3,765 older adults with DM and 12,989 older adults without DM. Six studies compared with or without DM and two studies compared fallers with non-fallers with DM. Risk factors for falls included impaired cognitive function, diabetes-related complications (peripheral nerve dysfunction, visual impairment), and physical function (balance, gait velocity, muscle strength, and severity of physical activities). Conclusions: People who are 65 years of age or above with DM have increased risk of falling caused by impaired cognitive function, peripheral nerve dysfunction, visual impairment, and physical function in community-dwellers. For adults who are 65 years of age or older with DM, research fields and clinical settings should consider therapeutic approaches to improve these risk factors for falls.

방송과 관련된 디지털 기술과 통신 기술의 급격한 발전은 방송 산업의 다양화와 컨텐트의 수적 증가를 유도한 반면 시청자의 시청 환경을 고려하는 편의성과 최적 정보전달 기술의 발전은 더디게 진행되어왔다. 본 논문에서는 국내에서 최근 상용 서비스가 실시된 양방향 TV 환경에서 시청자의 행위, 선호도, 성향등을 분석하여 시청자에게 최적화된 방송 채널과 프로그램을 추천함으로써 시청의 편의성을 증대시키는 개인화 시스템을 제안하고 제안된 개인화 시스템이 양방향 방송 산업에 미치는 영향성 및 가치사슬 지원 범위를 측정 하도록 한다.

뇌성마비 아동의 재활치료에 있어서 부모 참여에 대한 고찰
황수진,하승희 한국장애인재활협회 2013 재활복지 Vol.17 No.3
발달장애아동의 재활치료에 있어서 치료실과 가정과의 관계는 매우 중요하다. 특히 뇌성마비와 같은 만성적인 장애로 신체적인 운동장애뿐만 아니라 감각장애, 언어장애 등이 복합적으로 나타나는 중복장애의 경우 가정에서의 부모의 역할이 더욱 강조되어야 한다. 따라서 본 연구는 뇌성마비 아동의 재활치료에 있어서 부모 참여에 대한 지원 방안을 살펴보기 위해 뇌성마비 아동 어머니 4명과 재활치료 전문가를 3명을 대상으로 재활치료와 부모교육 프로그램의 경험과 개선사항 등을 주제로 심층면접을 실시하였다. 질적 분석결과 2개의 범주에서 총 8개의 하위범주가 도출되었다: (1)가족치료를 통한 부모 참여: 가정에서의 지속적인 연습, 전문가와 상담, 부모교육 프로그램 참여, 가족치료의 어려움, (2)장애아동 부모단체 활동을 통한 부모 참여: 정서적지지, 정보 공유, 지역사회와의 협력, 장애아동 부모단체 활동의 어려움. 재활치료에 있어서 효과적으로 부모 참여가 이루어지기 위해서는 가족치료를 위한 전문가들의 지지와 장애아동 부모단체를 통한 통합적인 사회적인 지지가 제안되었다. It is important to build a relationship between parents and therapists in rehabilitation treatments. Especially the importance of parents’role at home should be emphasized for effective rehabilitation treatment for children with cerebral palsy as a multiple-handicapped children that had a physical disorders as well as disturbance of sense, and speech-language disorders. The purpose of this study was to develop a support of parents involvement that helps the children with cerebral palsy's rehabilitation treatment. 4 mothers of children with cerebral palsy and 3 rehabilitation therapists participated in the focus group to share their experiences and opinions. Two primary themes and eight sub-themes emerged from qualitative analysis: (1) Parent involvement through family therapy: continuous practice at home, professionals counseling, parent training programs, and the difficulties of family therapy, (2) parents involvement through parents' association with the disabled: emotional support, information sharing, collaboration with local communities, and the difficulties of parents' association with the disabled. We suggest that parents need a professional supports from rehabilitation specialists and social supports by handicapped children’s parents association for effective parents involvement.
