Today, the elderly is increasing gradually in the Republic of Korea society and this problem will be more serious in the near future. Therefore, engineering support for aged people is required. We are establishing a new field of healthcare engineering for elderly people and aiming to support for aged people and disabled people using adaptive control and instrument technology. In this paper, the goal is to implement the shared control of a robot mobility aid for the elderly. As using this type of assistive technology to be useful by its intended user community, it supports elderly people and handicapped people to live independently in their private homes. The interface transforms the force applied by the user into the robot's motion. Devices like buttons, joysticks, and levers already exist for relaying user input; however, they require hand displacement that would loosen or otherwise release the user's hold. Such interfaces make operation very difficult and potentially unsafe. Therefore, we propose a shared control system. It's safe more than joysticks and buttons. The shared control is a means of registering the user's intention through physical interaction. It's an important component in the development of robotic elderly assistant. The concept of shared control describes a system which is two or more independent control systems. We are using that the three component blocks consist of pressure sensor (flexible force sensor), circuit of measurement and transfer function. Experimental trials of this paper have been tested at the indoor environment. The robot is able to know the user intended direction through haptic device were logged along with the robot's force sensor.

최근, 사람과 사람 사이의 상호작용이 증대됨에 따라 개인의 명함이 개인정보교환의 매개체로써 많이 이용되고 있다. 이로 인해 개인이 소유하게 된 명함의 수는 방대해져 중요한 명함이 유실되거나, 원하는 명함의 검색이 매우 어려운 일이 되었다. 그리고 명함은 자신의 개성을 표현할 수 있는 매개체이므로, 사람들은 개성이 담겨 있는 명함을 만들고자 하는 요구가 많다. 따라서 이런 오프라인 상 명함관리의 문제점 해결과 개성표현 모두를 만족시키기 위해 명함제작과 관리를 통합시킨 새로운 시스템을 제안한다. 본 논문에서는 모바일 단말을 통해 시간과 장소에 구애 받지 않고 명함전송, 명함요청과 같은 기본적인 기능뿐만 아니라, 개인이 창작한 사진과 동영상을 담은 명함을 제작할 수 있게 한다. 그리고 개인정보표현 표준 규격인 vCard를 따름으로써 vCard를 지원하는 다른 응용 프로그램에서도 제작된 명함의 이용이 가능하다. 마지막으로 명함에 삽입된 동영상과 사진의 내용기반검색을 통한 새로운 명함검색 기법을 제공한다. 따라서 표준화를 지원하는 명함에서부터 개인의 개성을 표현한 명함의 제작 및 관리까지 만족시키는 하이브리드형 명함시스템을 제안한다.

The people information is distributed in various forms such as database, web page, text, and so on, where the world wide web is one of the main sources of publicly-available people information. It has a characteristic that the information on people is intrinsically temporal. Therefore, the reconstruction of the information is needed for an individual or a company to use it efficiently. In order to maintain or manage the temporal people information, it must distinguish the variable information from invariable information of people. In this paper, we propose a method that constructs an ontology based on events to manage the variable people information efficiently. In addition, we present a system which reconstructs people information that satisfies the users' demand with the ontology.

In a broad sense, the healthcare system refers to the conventional medical service for the field of treatment. From head to toe, our whole body corresponds to the subject of the medical service. In this paper, we discuss the abnormality of flexion and extension in general elbow disease. Flexion and extension refer to flexing and extending of the arm while it is set to be at 90 degrees. In this case, if the angle of the arm is remarkably small or is accompanied with pain, there is an abnormality that occurs in the elbow. We tested the flexion and extension of the elbow for 100 people in their 50s and calculated the number of people for each case. Afterwards, we classified people with abnormalities in flexion and extension and presented the respective treatment methods. In this paper, a system was constructed for the treatment of musculoskeletal disorders.

Candida spp. are yeast form fungi, which cause an opportunistic infections in a immune suppressed patients however it is a normal flora of the respiratory system, the gastrointestinal system, and the urogenital system of healthy person. It is investigated that the distribution of Candida spp. cause an oral disease from oral cavity of healthy people and also identified Candia dubliniensis. Distribution and identification of the yeast form fungi in oral cavities of healthy people was investigated by an automatic identifier, VITEK2 system. We found 21 strains of Candida albicans, 3 strains of Candida famata, one strain of Candida tropicalis, Candida haemulonii, Candida krusei, and Candida dubliniensis. In addition, one strain of Cryptococcus spp., Saccharomyces spp., and two unknown strains were isolated. Candida dubliniensis which forms a mass by more than 2 chlamydospores was isolated from a healthy person for the first time. Candida dubliniensis was not grown at $42^{\circ}C$ whereas Candida albicans was grown well. It is known that Candida dubliniencis was isolated in AIDS while it is found in healthy people from this study, which will be helpful to investigate the distribution of Candida spp.

Recently, the korean statistical information service reported that the elder people aged over 65 years take 11 percentage point of all population, indicating that the hyper-elder era will advent shortly. As a result, there are remarkably increasing demands for providing self-organizable home agent system for elder people. Of the home agent system, the ubiquitous home service is known to be useful to overcome this problem. However, current ubiquitous home services limited to provide functional services, and it can be observed that there is lack of consideration for elder-support products which are closely interacted with elder people in the living situation. In this paper, we analyze senior aids products that can be combined to the ubiquitous home service, and propose design procedure for senior aids products that can be applied to self-organizable ubiquitous services. We studied characteristics of elder people, current state of affairs for senior aids products, and home services that are highly required by elder people. Moreover, we observed that the ubiquitous home services related to health, safety, and amenity are urgently needed, and those services can be categorized according to residential areas. Following those observances, we proposed a design principle based on the universal design paradigm to provide self-organizable ubiquitous home service environment for elder people using senior aids products.

The main purpose of this research is to introduce PsyCap(Positive Psychological Capital) and new leadership helping ordinary people to create positive thinking and leading to social integration in South Korea. Additionally, by looking at conventional leadership theories and by applying the PsyCap to leadership based on causal loop analysis, this study is to seek new approach which political leader is able to communicate with the people and can help the people to build positive mine. Throughout this study, there are several important implications how political leader can lead to social integration and stable political development in South Korea. In particular, when political leader encourage the people to have confidence to take on and put in the necessary effort to succeed at challenging tasks, when political leader make the people a positive attribution (optimism) about succeeding now and in the future, when political leader help the people to persevere toward goals and redirection paths to goals (hope) in order to succeed, and when political leader make the people beset by problems and adversity environment to overcome these concerns, it can be expected political leader to build social integration and the people to create positive thinking which has been emphasized by political leader in South Korea. Finally, 21st century has required new political leadership that the people are able to make positive psychological capital composed by optimism, hope, confidence, and resilience.

The rapid aging of the veterans has reached a level that cannot handle the demand for veterans care through the existing veterans care infrastructure. Therefore, it is urgent to improve the quality of the overall service of veterans due to the deterioration of the quality of nursing services for veterans with various underlying diseases compared to general patients and the long-term waiting for admission to the veterans care center. In this situation, about 640,000 people are admitted to veterans care institutions, but only about 5% of them can enter the veterans care center smoothly. As of June 2020, the number of people waiting to enter the veterans care center exceeds 1,000, including 520 at Suwon Veterans Nursing Home, 1 at Gwangju Veterans Nursing Home, 47 at Gimhae Veterans Nursing Home, 39 at Daegu Veterans Nursing Home, 86 at Namyangju Veterans Nursing Home.. Therefore, in order to predict those who want to enter the Veterans Nursing Home and wait for admission, and to find an important basis for resolving the long-term atmosphere, the ratio of future care providers is predicted in 2022-2050 and 2022-2024 to establish a cooperative system. As a result, 6,988 people in 2022, 6,797 people in 2023, and 6,606 people in 2024 can be admitted when 'preferred linkage', and 12,057 people in 2022 when 'expanded linkage'. It was found that 11,837 people in 2023 and 11,618 people in 2024 could be admitted. This was derived by estimating the percentage of people who wish to enter the Veterans Nursing Home when linking private nursing homes, and eventually "additional acceptance" of 22.5% in 2022, 20.9% in 2023, 19.4% in 2024, and 38.8% in 2023, 36.3% in 2023, and 34.1% in 2024 are most efficiently available.
