The purpose of this research is to analyze priority of the elderly user interface (UI) evaluation criteria based on user's lifestyle. Since the elderly population will occupy over 20% of the all Korean population in the near future, we need to know older users' needs and information because elderly users will be main customers in the super-aged society. This paper investigated the definition of elderly users and characteristics demographically, socio-economically, and physically/cognitively. A total of 238 questionnaires from older users were analyzed based on a segmentation table for the elderly developed by the previous study. According to factor analysis and cluster analysis, 6 types of lifestyle and 4 groups of the elderly users were classified, respectively. The priority of UI evaluation criteria for large electronic home appliances and mobile products was analyzed by analyses of variance (ANOVAs). The results indicated that the priority of (physical, emotional, and cognitive) UI criteria was significantly different among elderly users' lifestyles for both home appliances and mobile products. Consequently, the results of this study may help the company develop some competitive silver products and give higher satisfaction to the elderly users by suggesting different priority of UI evaluation criteria according to the target elderly group. The results may also contribute to revitalize national economy by significantly increasing senior market shares.

All of us have no time to predict and prepare for a rapidly-approaching future change in the 21st century, thereby being reality that we feel uneasy about future society. Accordingly, there is necessity for re-consolidating environment and daily culture in preparation for future society, namely, aging society. Given well preparing for super-aging society that will approach in the future, by which this effort becomes what bad luck often brings good luck, our country's role is thought to get probably bigger even in the globally silver industrial market in near future. We need to synthetically recognize a human being's aging psychological and physical conditions through the aging experience exhibition available for publicizing properly this historical phenomenon, and to pay more attention to importance of interaction between a human being and product environment. The experience exhibition is a concept for the exhibition form and the spatial composition, which emphasized interaction, with having escaped from the simply exhibition space. Given trying to communicate information more scientifically with escaping from the conventional exhibition of seeing and listening, it is also important to research Into the basis for exhibition as the experience space based on interaction. After all, a human being's aging is the unavoidably future phenomenon. And, importance of environment, which influences a human being, is very mutual as well. Our country is desired to develop a research on interaction of the exhibition experience space available for broadening recognition of senior-friendly and for properly experiencing this, thereby being an opportunity that the business entity, which plans silver industry, and the academic circles, which research and develop this, do mutually cooperate and can make silver industry grow further.

Objective: This study developed a new shower carrier prototype to reduce caregivers' muscle burden and to increase use convenience by reflecting the needs of domestic long-term care institutions. Background: In the long-term care institutions, one of the ADL(Activities of Daily Life) factors is bathing/showering. Recently, bath/shower-assisting equipment is actively being introduced in care institutions to reduce the caregivers' care cost, but most of the domestic equipment was designed to imitate foreign products and rarely reflected the needs of care institutions. Method: Based on Korean elderly people's body information, the bed size(length: 1,900mm, width: 650mm) was set-up, and a variable headrest with a newly designed headform was developed to provide the comfort for the elderly and convenience for caregivers. To reduce caregivers' muscle burden on transferring and showering activities, a 3-step column lifting module equipped with dual actuators(lowest/highest levels from the ground: 600/1,100mm, Stroke: 500mm) was developed, and the wheelbase parameter(length: 1,250mm, width: 580mm) was defined securing the turn-over safety of the shower carrier. The drivability tests were performed for the prototype and foreign product, and the male and female subject's muscle activities were measured through the tests. Results: The structural stability of the shower carrier prototype was secured by finite element analysis, and the muscle activities of the subjects through the drivability tests largely decreased in the prototype, compared to the foreign product. Conclusion: In this study, a new shower carrier prototype was developed to possibly reduce caregivers' muscle burden and to increase use convenience based on the needs of long-term care institutions. It was expected that the drivability performance of the prototype could be relatively superior to that of the foreign product. Application: The results obtained from the study can be applied for the optimal development of a shower carrier including other equipment to effectively care for the elderly.

The balance ability significantly decreased in the elderly because of deterioration of the neural musculature regulatory mechanisms. Several studies have investigated methods of improving balance ability using real-time systems, but it is limited by the expensive test equipment and specialized resources. Recently, Kinect system based on depth data has been applied to address these limitations. Little information about accuracy/inaccuracy of Kinect system is, however, available, particular in motion analysis for evaluation of effectiveness in rehabilitation training. Therefore, the aim of the current study was to evaluate accuracy/inaccuracy of Kinect system in specific rotational movement for balance rehabilitation training. Six healthy male adults with no musculoskeletal disorder were selected to participate in the experiment. Movements of the participants were induced by controlling the base plane of the balance training equipment in directions of AP (anterior-posterior), ML (medial-lateral), right and left diagonal direction. The dynamic motions of the subjects were measured using two Kinect depth sensor systems and a three-dimensional motion capture system with eight infrared cameras for comparative evaluation. The results of the error rate for hip and knee joint alteration of Kinect system comparison with infrared camera based motion capture system occurred smaller values in the ML direction (Hip joint: 10.9~57.3%, Knee joint: 26.0~74.8%). Therefore, the accuracy of Kinect system for measuring balance rehabilitation traning could improve by using adapted algorithm which is based on hip joint movement in medial-lateral direction.

Falling is one of the major public problems to the elderly, resulting in limitations of daily living activities. It can be induced by the functional loss of the balance ability and muscle strength in the elderly. It has been, however, not well investigated to suggest an effective methodology improving the balance ability and muscle strength for the prevention of the falling due to lack of information about the characteristics of the balance and muscle activations responded to the dynamic motions. The aim of the current study is, therefore, to identify the characteristics of the balance and muscle activations responded to the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. For that, a motion capture system with eight infrared cameras, surface electromyogram system and Wii Fit system with a customized variable unstable base were used and kinematic and kinetic data obtained from the systems were analyzed for five healthy male($24.8{\pm}3.3years$, $177.4{\pm}2.0cm$, $73.9{\pm}12.9kg$, $23.5{\pm}4.0kg/m$). The results showed that the characteristics of the balance and muscle activations were differently responded to between the dynamic motions in Anterior-Posterior(AP) and Medial Lateral(ML) directions. These findings may indicate that customized dynamic motions should be applied to the training of the balance ability and muscle strength for the effective prevention of the falling. This study may be meaningful to providing basic information to establish a guideline improving effectively the balance ability and muscle strength.

본 연구는 2018년 보건복지부에서 발표한 「독거노인 종합지원대책」을 중심으로 독거노인에 대한 제도적 지원의 문제점 및 해결방안에 관하여 연구하였다. 연구결과는 다음과 같다. 첫째, 맞춤형 독거노인 지원제도를 도입해야 한다. 독거노인의 생활만족도 향상을 위해 가장 기본적인 일상생활 관련 욕구에 맞는 프로그램 개발이 필요하며, 서비스를 연계할 구체적인 방안과 지원체계가 마련되어야 한다. 둘째, 독거노인에 대한 사회적 관심도 증대가 필요하다. 독거노인에 대한 문제해결은 독거노인에 대한 사회적 관심도가 선행되어야 한다. 이를 위해서는 사회적 관계망의 강화가 필요하다. 셋째, 독거노인을 위한 법률 제·개정을 제안한다. 기존 법률의 일부 개정만으로는 한계가 있고, 다양한 노인일자리 유형에 대한 기준과 정의, 노인일자리 사업 전담기관을 포함한 전달체계에 대한 재정비, 근로자성 관련 규정, 노인생산품 우선구매제도 등 개별 법률 제정을 통하여 해결하는 것이 바람직하다. 결론적으로 독거노인에 대한 복지지원은 종합적이고 포괄적이어야 한다. 독거노인의 복지는 우선적으로 맞춤형 돌봄서비스가 시행되어야 하며, 사회적 관심도의 증대를 토대로 해서 독거노인에 대한 사회적 지지를 향시키고, 독거노인을 위해 법제·개정이 능동적이고 선제적으로 이루어져야 한다.
