우리 사회에서 개인이 복용하고 있는 약물의 종류와 수가 점점 늘어나고 있다. 약물의 사용이 증가하면서 때로는 치명적일 수 있는 약물 오남용 또한 빈번히 발생하고 있으며 특히 노년층과 같이 약품을 정확하게 구별할 수 없는 사람들은 더욱더 그 위험에 노출되어있다. 본 논문에서는 사용자가 간단한 사진을 찍는 행위를 거치면 약물의 정보를 제공하고, 복용법을 알 수 있는 모바일 애플리케이션에 관하여 기술한다. 이를 구현하기 위하여 세밀한 시각적 분류 (Fine-Grained Visual Categorization, FGVC) 기법과 광학 문자 인식 (Optical Character Recognition, OCR) 기법을 결합한 인공지능 모델을 사용하였으며, React Native 를 사용하여 운영체제에 종속되지 않도록 애플리케이션을 제안한다. 이 애플리케이션은 노년층에 친화된 UI/UX 로 디자인되었으며, 약물의 정보 제공 이외에도 개인 약물 관리, 주변 약국 길 찾기 등의 편의 기능을 통해 노년층에 삶의 질 향상을 기대할 수 있을 것이다.

최근 고령화 사회로 인해 전 세계적으로 노년층 인구수가 증가하고 있다. 하지만, 노인들의 신체 능력은 더욱 약화되고 있으며 병원을 찾아가 진료 및 재활을 받는 것은 신체적으로 부담이 갈 것은 자명한 사실이다. 또한, 재활 치료는 본인이 느끼는 것에 따라 진단 결과가 나오며 의사 또한 정확한 수치를 확인할 수 없어 제대로 된 진단 결과를 받을 수 없다는 문제가 있다. 본 논문은 이러한 문제를 해결하기 위해 병원을 직접 찾아가지 않고, 자택에서 측정 및 재활이 가능한 시스템을 제안한다. 재활 치료를 받는 환자의 신체정보를 근전도 센서, 심박 수 센서 등을 활용하여 상시 체크를 하고 의사가 실시간으로 모니터링을 하며 환자의 상태를 확인 및 상담과 조치를 취할 수 있는 시스템을 만들어 최근 증가하고 있는 노년층들이 신체적, 금전적 제약을 받지 않고 진료 받을 수 있게 할 것이다.

본 논문은 노인의 외로움 해소를 위해 Unity 를 이용한 VR 멀티 시뮬레이션 게임 프로그램의 설계 및 개발 내용을 다루고 있다. 본 시뮬레이션은 주 타겟층인 노년층을 고려하여 최소한의 간단한 조작법을 지향하고 있으며 따라서 3D 1 인칭 어드벤처 시점, 바라보는 방향으로 이동하는 연속 이동방식을 채택하였다. 서버를 이용하여 2 인 이상의 멀티 시뮬레이션 환경을 지원하며 텍스트 채팅이 아닌 음성 채팅을 통하여 시뮬레이션 유저들 간의 소통을 지원해준다. 다른 유저들과 함께 GameObject 의 상호작용을 보며 대화를 이어가거나, 낚시, 채집 활동을 할 수 있다. 이로 하여금 노년층의 외로움 해소를 도울 수 있도록 개발하였다.

This study aimed at reviewing research trends and issues of domestic game studies for the elderly. Total 41 KCI papers were chosen for the final analysis and the author explored the research subjects, research fields, and research methods. Results showed that the majority of research subjects were game development and game effects. It was also found that most of the research has been done in interdisciplinary and engineering fields. In terms of research methods, game development and experiment were most popular and widely used methods. By summarizing the important terms, major research issues of game studies for the elderly were explored in conclusion and discussion.

For the development of a curriculum of the serious game for the elderly in preparation of senior society, we have surveyed students of both college of humanity and college of engineering for their perception of importance and necessity on the subjects prepared by this team. We analyzed their common points and different points, and developed a new interdeciplinary curriculum for students in both college. The curriculum has been opened in the last semester successfully.

To solve the digital divide of the elderly, various institutions are educating how to use various smart devices for the elderly. However, it cannot be expected to have a great effect due to the disadvantages of instructor-to-face education and the learning characteristics of the elderly. Accordingly, educational contents using digital devices using robots for the elderly were developed. In this study, Evaluation Indicators were developed to evaluate the usability of digital education using robots. Also, by using usability evaluation based on the developed Evaluation Indicators, we tried to verify the usability of education using robots and to confirm the possibility of expanding the application area. In order to successfully apply the developing robot technology to various fields, it is essential to verify the usability of contents using robots, and this study on Evaluation Indicators and Evaluation methods is expected to serve as a foundation.

This research examines classifying and characterizing breast form's classification on elderly women, 242 subjects from 55 to 75 years of age participated. 27 direct anthropometric measurement were applied to classify the breast typesl. We analyzed measurement data using factor analysis, cluster analysis, analysis of variance. The results of the study were as follows. 1) 55-64 aged group was taller and higher than 65-79 aged group. Typical breast form in 55-64 aged group was more obese than breast form in 65-79 aged group. 2) We extracted 5 factors(obesity of breast, height of breast, height of breast items, location & size of breast, width of upper chest & shouldet length, height of breast & lower length of nipples) from total items through factor analysis. 3) Through cluster analysis, we categorized 3 clusters. Namely, type 1; characterized the best slender type, type 2; characterized middle sized type, type 3: characterized obesity type. Type 2 is the typical type on elderly women.

There have been active research activities to use neural networks to analyze OCT images and make medical decisions. One requirement for these approaches to be promising solutions is that the trained network must be generalized to new devices without a substantial loss of performance. In this paper, we use a deep convolutional neural network to distinguish AMD from normal patients. The network was trained using a data set generated from an OCT device. We observed a significant performance degradation when it was applied to a new data set obtained from a different OCT device. To overcome this performance degradation, we propose an image normalization method which performs segmentation of OCT images to identify the retina area and aligns images so that the retina region lies horizontally in the image. We experimentally evaluated the performance of the proposed method. The experiment confirmed a significant performance improvement of our approach.

The Korean society has been changed to the aging one. The number of elderly people has been in creasing rapidly. For their social and economic activity, more convenient transport services have to be offered. Specifically, increasing mobility is one of the most urgent policies for them. One action of the policy in Seoul has introduced low floor buses since 2003. This paper shows how low floor buses affect on passengers' boarding and alighting time through the field survey. In the analysis of the survey results it has been found that the low floor buses can reduce average boarding time by 0.8 sec, especially, by 1.1 sec (about 36%) for elderly passengers. These outcomes expect total bus operating hours as well as headways could be reduced, and operating cost and passengers' waiting time could be saved.
