In this paper, we propose a barrier-free course route navigation service named "Theme Road" aimed at improving the mobility and convenience for elderly electric wheelchair users with walking disabilities. To achieve this goal, we conducted a user survey through shadowing and in-depth interviews to gather insights on the challenges experienced by elderly electric wheelchair users. We identified potential solutions for each inconvenience through co-creation workshops, resulting in a set of design considerations and app functionalities. Using persona development and service scenarios, we designed and implemented the "Theme Road" service as a dedicated navigation application for barrier-free course navigation. Unlike conventional route navigation and mapping services, our study stands out by offering a unique approach that combines recommended destinations and safe routes based on experiential analysis from elderly electric wheelchair users.

Using the bond-based peridynamics and the parallel computation with binary decomposition, an adjoint shape design sensitivity analysis(DSA) method is developed for the dynamic crack propagation problems. The peridynamics includes the successive branching of cracks and employs the explicit scheme of time integration. The adjoint variable method is generally not suitable for path-dependent problems but employed since the path of response analysis is readily available. The accuracy of analytical design sensitivity is verified by comparing it with the finite difference one. The finite difference method is susceptible to the amount of design perturbations and could result in inaccurate design sensitivity for highly nonlinear peridynamics problems with respect to the design. It turns out that $C^1$-continuous volume fraction is necessary for the accurate evaluation of shape design sensitivity in peridynamic discretization.

When an old-fashioned contents are combined with the digital contents, it will be emerged as q results of new genre. And if it is applied for business and industry, to develop it into a digital culture. Animentary combines the attributes of the animation in the documentary. Through this convergence content, old story is convert to new story and is recreated with a new method of storytelling and imagetelling. This research is to discover, convert, and recreate a story buried in the everyday life and also is to propose animentary production process recreated in the digital paradigm.

The purpose of this study is to evaluate the cognitive functional improvement of cognitive occupational therapy using cognitive function, activities of daily living (ADL) executive function and depression tests in community living elders with mild cognitive impairment (MCI) and dementia. Thirty two elders who diagnosed MCI (n=13) and dementia (n=19) were enrolled in this study. They visited to local elder welfare office and nursing care home from Feb. 2012 to Jun. 2012. They received occupational activity program in terms of physical activity, cognitive function and occupational function of Craft as the manner of a session per week for 8 weeks. The cognitive function, executive function, depression score were improved in both group. Furthermore in MCI participants, cognitive function scores for concentration and memory functions were significant improved more than dementia subjects. Further studies dealing with the development of novel occupational program for cognitive function improvement and its preventive effects were needed.

This paper presents a facial animation method that enables the user to select a sequence of facial frames from the facial expression space, whose level of details the user can select hierarchically Our system creates the facial expression space from about 2400 captured facial frames. To represent the state of each expression, we use the distance matrix that represents the distance between pairs of feature points on the face. The shortest trajectories are found by dynamic programming. The space of facial expressions is multidimensional. To navigate this space, we visualize the space of expressions in 2D space by using the multidimensional scaling(MDS). But because there are too many facial expressions to select from, the user faces difficulty in navigating the space. So, we visualize the space hierarchically. To partition the space into a hierarchy of subspaces, we use fuzzy clustering. In the beginning, the system creates about 10 clusters from the space of 2400 facial expressions. Every tine the level increases, the system doubles the number of clusters. The cluster centers are displayed on 2D screen and are used as candidate key frames for key frame animation. The user selects new key frames along the navigation path of the previous level. At the maximum level, the user completes key frame specification. We let animators use the system to create example animations, and evaluate the system based on the results.

XML은 의미적으로는 동일하거나 혹은 유사하지만 서로 다른 구조의 XML 문서들을 허용하므로 XML 문서들을 대상으로 하는 검색, 클러스터링 등의 응용에서는 XML 문서들간의 유사도 계산이 선행되어져야 한다. XML 문서간 유사도를 계산하기 위해서는 문서의 구조 정보인 엘리먼트들과 이들 엘리먼트들의 계층적 구조가 고려되어져야 한다. 본 연구에서는 두 XML 문서가 얼마나 유사한 경로들을 공통으로 가지냐를 두 문서간의 유사도로 보고, 경로 유사도 계산식과, 이를 기반으로 하는 문서 거리 및 문서 유사도 계산식을 정의하여, 유사도 계산 기법을 제안한다. 제안된 기법과 기존 유사도 계산 기법들을 예제 문서들을 통해 계산결과를 비교한다.

당뇨라는 병에 걸린 지도 벌써 12년 째라는 이순애 씨. 원미동사무소 탁구장에서 만난 이씨는 오랫동안 당뇨병을 앓고 있다고 믿어지지 않을 만큼 밝고 건강한 모습이었다. 50대 중반인 이씨가 12년 째 당뇨병을 앓으면서도 같은 연령대의 비당뇨인들보다 더 건강을 유지할 수 있는 비결을 들어봤다.

This study attempts to examine the factors influencing the Caregiving responsibility of sibling without disability on their adult siblings with intellectual disability. For this purpose, a questionnaire survey was conducted on siblings without disability who have adult siblings with intellectual disability aged 18 years old or more and also who use services provided by 8 welfare centers for persons with disabilities in Seoul. With 132 valid responses, multiple regression technique was adopted in exploring a model for characteristics of adult with intellectual disability, a model for characteristics of siblings without disability, a model for relationship factors, and a comprehensive model. The findings of the study showed that the degree of disability in the model for characteristics of adult siblings with intellectual disability and the intimacy of siblings and social support in the model of relationship factors were significant. The result of the comprehensive model revealed that the degree of disability, the gender of the siblings without disability, the intimacy of siblings, and social support were significant. Especially, the relationship factors including the intimacy of siblings and social support were found to be the most significant factors in order to explain the caregiving responsibility. The findings of the study suggest that sibling program needs to be developed and disseminated in order to increase the understanding and the trust between adult with intellectual disability and sibling without disability, that a help is critical for adult with intellectual disability to extend the social network in which sibling without disability receives support from sibling without disability, family, friends, and other acquaintances around, and that different approach is needed in order to reduce caregiveing difficulties depending on the dependence of disability.
