To enhancing the exercise effect, exercise management systems are introduced and generally used. They create the proper exercise program through exercise prescription after determining the personal body status. When the exercise programs are created, they will consider $2weeks{\sim}3months$ period. And, existing exercise programs cannot respect with personal exercise habits or exercise period which are changing variedly. If exercise period is long, it can be caused inappropriate exercise about user current status. To solve these problems in legacy systems, this paper proposes a Context Aware Exercise Model (CAEM) to provide the exercise program considering the user context. Also, we implemented that as Intelligent Fitness Guide (IFG) System. The IFG system is selectively received necessary measurement values as input values according to user's context. If exercise kinds, frequency and strength of user are changing, that system creates the exercise program through exercise optimization algorithm and exercise knowledge base. As IFG is providing the exercise program in a real time, it can be managed the effective exercise according to user context.

건강, 운동에 관한 관심이 고조되고 레저를 즐기는 사용자층이 확대되어 감에 따라 다양한 종류의 레저형 시뮬레이터에 대한 개발이 이루어지고 있다. 그러나 단순 운동을 위한 스포츠 시뮬레이터는 흥미를 반감시켜 지속적인 운동에 대한 저해하는 요소가 된다. 본 논문에서는 이런 시뮬레이터의 한계를 극복하기 위해 다양한 콘텐츠를 접목시킨 스포테인먼트형 자전거를 제안한다. 이를 위해 개인 신체 정보를 입력을 통해 프로그램 추천 및 이력관리가 가능하고 흥미요소인 게임, 음악 등을 동시에 즐기면서 운동을 할 수 있는 자전거 시뮬레이터 UXBike 시스템 개발한다. 이는 보편화된 운동 레저 시뮬레이터와 콘텐츠의 융합을 통해 사용자의 몰입도 향상 및 지속적인 관심을 갖게 하는 계기가 될것이라 판단된다.

우리나라의 손 마비환자의 수는 매년 증가하고 있다. 병원에서 진행하는 일반적인 재활치료는 비용이 많이 들기 때문에 손 마비환자가 가정에서 재활운동을 하는 경우가 많아지고 있다. 본 논문에서는 손 마비환자들이 가정에서 재활운동을 할 시, 개인별 맞춤 케어를 제공해주기 위하여 스마트 글러브를 이용한 개인별 움직임 패턴을 분석하는 방법에 대해 기술한다. 손 마비환자는 움직임 패턴 분석을 통해 자신의 각 손가락 마비 정도를 정확히 인지할 수 있게 될 것으로 기대한다.

Wellness is IT fused with the user manage and maintain the health of a service can help you. If you are using an existing Fitness Center to yourself by choosing appliances that fit with the risk of injury in order to learn how the efficient movement had existed for a long time was needed. To resolve, use the personal training but more expensive cost of people's problems, and shown again in the habit of exercising alone will have difficulty. This paper provides a variety of smart phones based on a hybrid app with compatibility with the platform and personalized training market system. Users of the Fitness Center is built into smart phones in the history of their movement sensors or transmits to the Web by typing directly. This is based on exercise programs tailored to users via the training market. Personal training marketplace has a variety of users, check the history of this movement he can recommend an exercise program for themselves can be applied by selecting the. This provides users with the right exercise program can do long-term exercise habits can be proactive and goal setting.

To overcome the limitations of current evaluation procedures for floor vibration under crowd loading, two kinds of uncertainties associated with individual time lag differences and the complex behavior of crowd should be taken into account. The complex behavior of crowds has yet to be fully described, even though individual differences can be dealt with statistically. This paper proposes time lag considered (TLC) crowd model based on a probabilistic approach. The load reduction factor, which reflects the effect of a general degree of synchronization among crowd, is proposed. Extensive Monte Carlo simulations were carried out to determine various crowd behaviors by using the TLC crowd model proposed. The TLC crowd model can rationally treat the energy loss of various crowd patterns. This indicates that it may be used as a theoretical basis in refining dynamic load factor of crowd loading.

Diabetic patients need exercise, diet and medication to keep normal glucose levels. Therapeutic exercise is good to control the glucose level and emotional stability. There are many studies to identify the relationship between them glucose drop and exercise load. However, there are few studies on exercise system that patients can easily calculate appropriate exercise tolerance at home and coaching exercise by individual. This paper presents simple exercise tolerance test and exercise coaching algorithm with indoor bicycle. We measure the change of glucose level before and after exercise. Then, the coaching program for the exercise is established by the proposed exercise tolerance test. From the simulation results, glucose levels were decreased after exercise for all experimental participants. The diabetics kept the lowered glucose level after 30 minutes of exercise.

Y. W. KIM, Y. J. KIM, Mechanical Properties of Unilateral & Bilateral Movements in Isokinetic Knee Extension and Flexion. Korean Journal of Sport Biomechanics, Vol. 18, No. 3, pp. 83-92, 2008. The purpose of this study was to examine the mechanical properties and patterns of bilateral and unilateral movement under varying velocities and movement patterns. The unilateral and bilateral isokinetic knee extension and flexion were taken for three speeds of 13 healthy male subjects. Although there was bilateral facilitation at the speed of $450^{\circ}$/s for the bilateral movement of knee extension, as a whole there was less resultant torque and power of bilateral movement than summed unilateral under knee flexion and extension of 3 velocity condition. There was significant correlations between bilateral deficits within individuals observed for an the same movement($120^{\circ}-240^{\circ}$ flexion, $120-240^{\circ}$ extension, $240^{\circ}-450^{\circ}$ extension), which means that same agonist was recruited. On the contrary, although there was a tendency of a similar pattern of the individuals bilateral deficit according to the varying velocities, there was not a significant correlations between bilateral deficits of flexion and extension within individual, which means that different agonist was recruited. With the analyses of this results the individuals neuromuscular characteristics and the effecting factors for bilateral movement can be speculated upon.

The people who is returning to the community after hospital treatment are faced with the choosing where to proceed with rehabilitation exercise with an appropriate exercise specialists based on the current health condition of them. It is required to supprot a personalized exercise rehabilitation service (hereinafter referred to as ARES system) in the community based on individual disease information and health conditions based on hospital clinical data. In this study, we designed a resource management system for online-to-offline (O2O) based coach matching to improve accessibility with facilities and coaches for exercise rehabilitation in the community.

With the development of medical IT technology, personalized medical services are increasing in the silver industry era through the development of smart healthcare business. Therefore, in this paper, using various sensors in the Arduino environment, we implemented a finger modeling that can perform joint rehabilitation exercise that can provide personalized smart healthcare services. By measuring the activity of each individual finger joint using an Arduino-based flex sensor, it is intended to be used for personalized rehabilitation exercise in the smart healthcare field in the future.
