노인 치매예방프로그램에서 유아교육 콘텐츠의 활용가능성 탐구

양수경(Su-Kyung Yang),박정환(Jung-Hwan Park) 한국산학기술학회 2020 한국산학기술학회논문지 Vol.21 No.8

우리나라 노인들 평균수명이 늘어나면서 고령화로 인한 노인의 건강에 대한 문제가 많이 발생하고, 치매 발병률이 증가되고 있음으로 인해 사회적으로 심각한 수준에 이르고 있다. 치매는 발병 후 치료보다는 예방이 중요한 만큼 노인의 치매 예방에 관심이 모아지고 있다. 본 연구를 위해 양수경, 고보숙, 박정환(2019)의 연구에서 2000년~2018년까지 노인을 대상으로 한 치매예방프로그램의 국내 연구동향에서 분석한 통합프로그램 11편을 기반으로 유아교육에서 이루어지고 있는 놀이를 중심으로 한 노인 치매예방프로그램 문헌연구를 살펴보았다. 활동유형별로 음악, 언어, 신체활동이 각각 4개(40.0%)로 나타났고, 게임, 미술, 작업이 각각 3개(30.0%)로 나타났다. 그리고 무용, 문학, 전통놀이, 레크레이션이 2개(20.0%)로 나타났고, 요가와 생활은 각각 1개(10.0%)의 순으로 나타났다. 본 연구에서는 노인 치매예방프로그램에서 유아교육 콘텐츠의 활용 가능성에 대해 탐구하는 것을 목적으로 노인에게 있어 놀이는 유아 뿐만 아니라 노인들에게 신체 운동능력과 긍정적인 정서, 정서적 특성 등 매우 긍정적인 측면이 나타나고 있다. 노인들을 위한 유아교육 콘텐츠를 활용하여 치매예방프로그램을 개발한다면 지속적인 서비스 제공과 함께 집단활동의 경험과 정신건강을 유지하면서 여가시간을 긍정적으로 활용할 수 있을 것이라고 사료된다. As the prevention of dementia is more important than the treatment after the onset, attention has focused on the prevention of dementia in the elderly. For this study based on 11 integrated programs, we analyzed the domestic research trends of dementia prevention programs for the elderly from 2000 to 2018 in the study of Yang Su-gyeong, Ko Bo-sook, and Park Jeong-hwan (2019) We reviewed the literature research on the elderly"s dementia prevention program centered on play. By activity type, music, language, and physical activity were 4 (40.0%), respectively, and games, art, and work were 3 (30.0%), respectively. Dance, literature, traditional play, and recreation were 2 (20.0%), and yoga and life were 1 (10.0%), respectively. In this study, for the purpose of exploring the possibility of using the contents of early childhood education in the elderly dementia prevention program, play shows very positive aspects such as physical exercise ability, positive emotions, and emotional characteristics for the elderly. It is considered that if dementia prevention programs are developed using the contents of early childhood education for the elderly, they will be able to utilize leisure time positively while providing continuous services and maintaining group experiences and mental health.

In this paper, we research about Multi.agent control mobile robots using the GPS and Bluetooth modules. In this system, we used the sign board model whieh transmits the information to unspecified robots. And also for Multi-Agent system, we made three mobile robots and used GPS and Bluetooth modules for robot's coordinate awareness and search direction. All mobile robots are installed with GPS and Bluetooth modules, receive Master-mobile’s robot position coordinates from GPS and then transfer to all mobile robots located within the communication possibility area of the Bluetooth module. Each Slave-mobile robots receive the position coordinate from Master -mobile robot and calculate distance and direction between eaeh robot. We implement the transfer algorithm of Multi-agent robots, manufacture mobile robots for Multi-agent control and propose the method of 1:N real time communication. Finally , we calculate the distance between the positions of each robot using the GPS data.

Background and Objectives: The etiology and pathogenesis of chronic rhinosinusitis (CRS) is multifactorial and the role of infectious agents in CRS is not clear. S. aureus is the most frequent cultured pathogen in CRS and it expresses toxin, SEA, SEB and TSST-l, with superantigen (SAG) activity. Recently an importnat role of these staphylococcal toxins in CRS with nasal polyposis (CRSwNP) has been suggested. CRSwNP is a severe chronic inflammation characterized by massive infiltration of lymphocytes and eosinophils in the sinonasal mucosa and nasal polyp. However, there has been no further studies evaluating the properties of infiltrating T lymphocytes in CRSwNP and the cytokine profiles in activated T-Iymphocyte relating with SAGs. The aims of this study was to know what kind of T lymphocytes infiltrates in nasal mucosa and polyp tissue of CRSwNP, to analyze the cytokine profiles in infiltrating T cells, and to determine whether infiltrating T lymphocytes are specific for SAGs. Patients and Methods: Ethmoid sinus mucosa and polyp tissue samples were collected from 13 patients with CRSwNP and control sinus mucosa were obtained from 10 patient without CRS. Tissue infiltrating cells and T cells were isolated from tissue samples and flow cytometry, enzyme-linked immunosorbent assay, reverse transcriptase-polymerase chain reaction, in vitro T lymphocyte stimulation with S. aureus toxin were performed. Results: The mean total CD3+ T cell count was significantly higher in the mucosa and polyp tissue of patients with CRSwNP compared with control mucosa. Most infiltrating T cells in mucosa and polyp tissue were activated type, expressing CD45RO. CD8+ T cells were significantly increased in mucosa and polyp tissue of patients with CRSwNP compared with CD4+ cells IFN-γ was highly expressed in infiltrating T cells in both mucosa and polyp tissue, whereas IL-10 was expressed a small amount and IL-4 was not expressed. IFN-γ levels were significantly higher than IL-4 and IL-10 when isolated T cells were stimulated with SAGs in vitro. Conclusion: CD8+ T-cytotoxic and IFN-γ producing Th1 cells could paly an important role in the CRSwNP if sinonasal chronic inflammation is induced by SAGs.

시그너처 기반의 비디오 컷 감지 기법

홍수민,정성환 國立 昌原大學校 精報通信硏究所 1998 精報通信論文集 Vol.2 No.-

This paper presents a novel method of signature-based video cut detection in a transform domain. First, we partition a video frame into m x n cells and extract DC information from DCT coefficients. We construct frame signatures using extracted DC information and then compare neighbor frame signatures to detect a cut. The conventional methods have the problems of complex calculation, exhaustive processing time, and strong space. The proposed method is an effective and simple method which may solve the problems of these conventional methods. In the experiment using real AVI video data, our method shows about 88% cut detection rate.

The aim of this study was to evaluate the effect of various polymerization techniques on the microleakage of compomer restorations. Fifty extracted human premolar and molar were used and randomly divided into 5 groups. After cavity preparation, compomer (F2000) was filled according to the manufacturer's directions. All groups, except group 5, were filled using an incremental technique. Group 1was polymerized for 40 seconds at a continuous 485mW/㎠ with a VIP (Bisco, USA) light cure unit. Group 2 was polymerized for 20 seconds at a continuous 345mW/㎠ and then for 20 seconds at 645mW/㎠ with the VIP light cure unit. Group 3 was polymerized at 400mW/㎠, gradually increased to 50mW/㎠ per 10 seconds until 550mW/㎠ was reached; total 40 seconds with a Spectrum 800 (Dentsply Caulk, USA) light cure unit. Group 4 was polymerized for for 3 seconds using an incremental technique with a Flipo (LOKKi, France) light cure unit. Group 5 was polymerized for 3 seconds using a bulk fill technique with the Flipo light cure unit. The specimens were embedded with acrylic resin, and were sectioned with diamond saws in a mesiodistal direction along the longitudinal axis of the tooth so as to pass through the center of the restoration, and three surfaces (occlusal, pulpal, and gingival) were examined with SEM. The results were as follows; 1. Group 5 showed a significantly larger gaps compared to other groups on the gingival, occlusal, and pulpal walls. 2. All groups except group 5 had no statistically significant gap on the gingival, occlusal, and pulpal walls. 3. There was no significant correlation between the amount of enamel on the gingival and occlusal walls and polymerization shrinkage.

김충환,김종훈,김운형,하동명,이수경 한국화재소방학회 2001 한국화재소방학회논문지 Vol.15 No.3

본 연구는 국내와 외국의 건물 내장재 화재성능평가방법을 고찰하고 국내에는 도입되지 않은 실대 화재 실험인 Room Corner Test를 국내 내장재중 석고보드와 합판을 대상으로 그 적용성을 위한 실험을 진행하였다. 현재 국내 내장재의 평가규정은 Bench-Scale Test에 의존하고 있으나, 미국, 일본 유럽등에서는 Room Corner Test를 적용한 실질적인 재료의 화재성능평가를 시행하고 있다. 실험 결과, NFPA 265에 의한 석고보드 및 ISO 9705에 의한 합판의 성능은 양호한 것으로 판단되었다. 현재 국내 내장재에 적용되는 등급분류의 평가방법은 재료의 실제 화재성능 평가에 한계가 있으므로 향후 Room Corner Test의 적용과 더불어 Bench-Scale Test 결과를 토대로 화재성능을 예측하는 화재모델을 이용하는 평가 방법의 도입이 필요하다. The fire performance evaluation methods in Korea and overseas for interior finish materials were analysed and tested with gypsum board and plywood by using room corner test not adopted by domestic code until now. The results of gypsum board (thickness: 8 mm) and plywood (thickness: 4 mm) applying NFPA 265 and ISO 9705 test respectively are satisfied the assessment criteria. To assess a actual fire performance and classify fore hazard levels for interior finish materials, room-corner test and flame spread models should be adopted in building code and fire code to overcome limitations of current bench-scale test method.
