Many social and environmental changes have emerged due to the increasing size of the aging generation. This study explored the current status of the information leisure activity of the aging generation (computer use activity, internet service participation, social community participation and blogging, UCC, etc.) and the need for serious games among elderly consumers. It analyzed the current status of serious game and information leisure span as determined by experts on elderly care at the aging welfare institute. The research methods involved applying content analysis and focus group interviews. The results were as follows: The elderly are willing to enjoy the internet and economics networks. In particular, economic investment, economic news, health, meetings, and communication are the main internet search categories. The results for serious games are less interesting than those for IT participation. The components of usefulness in terms of serious games, as identified by care experts, are simplicity, a user-friendly interface, efficacy, and certainty in using the game device. Care experts recognize that serious games represent a supplementary device to traditional physical and emotional therapy.

Physical manifestations of aging due to the lack of exercise include the slowing down of motor learning, cardiopulmonary degradation, and the increasing difficulty to adapt to the environment. Aging is manifested with the lack of aerobic exercise work, decrease in muscular endurance, decline in skeletal and muscular strength, flexibility and agility, and the decrease in reaction speed and balance. Added to those are aging-related physiological changes, including the reduction of muscle bulk, increased body fat, decrease in total body water and basic metabolic rate as activities are reduced, and a decrease in cell and Lean Body Mass (LBM). These changes are known to cause problems. Interest and participation in appropriate physical activities among the elderly is needed to help them increase stamina, avoid diseases, maintain a clear intellect, and basically enable the elderly to live their daily lives as easy as possible. Therefore, physical activities are necessary for the elderly to enhance health-related factors. Special exercises should be performed for the enhancement of muscle function, muscle endurance, flexibility, agility, and balance. An accurate measurement of cardio-respiratory endurance and stamina through basic physical and cognitive characteristics of older adults is also required to ensure safety. Also, the development of a more scientific resistance exercise prescription system for the elderly is desperately needed.

LED TV 통합검사유닛은 LED BLU의 구동과 동시에 이상 유무 체크, AGING 작업 등 LED BLU를 테스트하기 위한 검사 장비이다. 기존 검사 유닛은 LCD의 종류와 크기에 따라 생산라인에서 검사 유닛을 교체해야 하는 불편한 점이 있어 본 연구에서는 한 가지 LED TV BLU 모델이 아닌 32 ~ 52인치의 다양한 LED TV BLU 모델을 수용할 수 있는 멀티형(통합형) 검사유닛으로 개발한다. 멀티형으로 개발하기 위해서 멀티 LED TV 통합검사유닛의 출력 전류를 80mA ~ 215mA의 범위로 다양한 출력이 되도록 만들고, LED BLU의 상태를 확인 하는 기능, 디밍(밝기 조절)기능 및 장시간 사용 시 열 발생 완화 기능 등을 구현한다. 또한 펌웨어 프로그램을 개발하고 업그레이드 할 수 있도록 하여 새로운 패널에 대해서도 지원할 수 있도록 개발한다.

소프트웨어 환경에서 업데이트는 버그를 수정하거나 보안패치를 하거나 새로운 기능을 추가시킨다. 그러나 기존의 업데이트는 사용자 인증을 고려하지 않고 단지 cd-key 만으로 사용자 인증을 하거나 웹 사이트에서 자유롭게 업데이트를 할 수 있다. 따라서 본 논문에서는 소프트웨어 환경에서 업데이트시 사용자와 서비스 제공자 사이에 패스워드 기반의 인증 방식을 적용하고, DRM(Digital Rights Management)에서 라이센스 개념을 도입하여 불법 사용자의 접근을 차단할 수 있는 방안을 제시한다.

OCXO (Oven Controlled X-tal Oscillator)의 주파수 모델이 holdover 알고리즘을 DP-PLL (Digital Processing-Phase Locked Loop) 시스템에 적용하기 위해 제안되었다. 이 모델은 온도와 OCXO의 노화에 따라 2차 다항식으로 간단하게 표현된다. 모델 변수들은 LSM (Least Squared Method)을 적용한 실험 데이터로부터 얻어진다. holdover 알고리즘은 다른 실험 데이터를 사용한 동일한 모델로 모의실험 할 수 있다.

Korea is ranked as the world's No. 1 country in its aging rate. While the interest and demand for health is rapidly increasing, the health status of the elderly is in the lowest among OECD members. Increased chronic diseases, the burden of medical costs and digital/untact changes of societies after COVID-19 have caused the direction of healthcare to be changed from treatment oriented to health care and prevention oriented, along with increased income levels and a desire for a healthy life. Amid this paradigm of change, the gap in health standards and health inequality for the elderly according to local structure and social conditions affects not only socio-economic but also the quality of life for individual senior citizen. Utilizing prior data of Aging Research Panel Survey, this study aims to compare and analyze health conditions and regional gaps which are significant influences on the satisfaction of the life of the elderly, and to suggest direction of studies for health care to provide solutions for health inequalities. The findings are intended to be a basic data for researching models of the New Normal Smart Healthcare System that bridge the health gap between the elderly and enhance life satisfaction with health care models suitable for regional characteristics in aging society.

We investigated the thermal characteristics of rotating anode X-ray tube to develop it for digital radiography by using computer simulation. The target which is the area of the anode struck by electrons is the most important component to get a long life of X-ray tube. So we analyze the thermal characteristics of the target and rotor assembly according to their emissivity by using ANSYS transient thermal simulation and then compare with the measured data of the target temperature operating in aging process of X-ray tube. Especially, keeping the lead coated layer as the role of metal lubricant on ball bearing enables to prevent the noise in rotating anode. The simulation result showed that its temperature was under the melting point of the lead in X-ray tube for digital radiography with 1.2 mm large focal spot 0.6 mm small focal spot and 150 kV tube voltage. We also investigated the relationship between the diameter of the anode shaft and the temperature of the anode and rotor assembly. It has been confirmed that the smaller anode shaft could be good for the rotor thermal characteristics.

Among the mainstream of this society has quickly adopted computer technology as part of their daily life, the ever growing group of elderly people, which will increase from 7% of the population in 2000 to being 14% just 18 years later, has been being exposed to computer using environment more than ever before. According to the survey of Korean government in 2005, the number of the elderly using computer has been rising actually, so web-based survey to identify housing needs of the elderly seems to have lots of possibilities as a useful tool for them. This study aims at comparing web-based survey tool with paper-based one, developed to identify the elderly needs on digital home planning. Experimental method and in-depth interview were employed. The participants were divided into 2 groups, web-based and paper-based survey group. Each group was controlled over by age (average 60 years old), gender and computer skill. As a results, web-based survy tool was revealed as effective to clearer understanding and causing more interests and more available, but less easy to handle than paper-based survey one. Through the in-depth interview, web-based survey tool was identified as a more effective method to figure out the needs of the elderly who are familiar with computer.

Maintenance of aging structures has attracted societal attention. Maintenance of the aging structure can be efficiently performed with a digital twin. In order to maintain the structure based on the digital twin, it is required to accurately detect the damage of the structure. Meanwhile, deep learning-based damage detection approaches have shown good performance for detecting damage of structures. However, in order to develop such deep learning-based damage detection approaches, it is necessary to use a large number of data before and after damage, but there is a problem that the amount of data before and after the damage is unbalanced in reality. In order to solve this problem, this study proposed a method based on Generative adversarial network, one of Generative Model, for generating acceleration data usually used for damage detection approaches. As results, it is confirmed that the acceleration data generated by the GAN has a very similar pattern to the acceleration generated by the simulation with structural analysis software. These results show that not only the pattern of the macroscopic data but also the frequency domain of the acceleration data can be reproduced. Therefore, these findings show that the GAN model can analyze complex acceleration data on its own, and it is thought that this data can help training of the deep learning-based damage detection approaches.
