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.

Objects Internet-based healthcare services provide healthcare and healthcare services, including measurement of user's vital signs, diagnosis and prevention of diseases, through a variety of object internet devices. However, there is a problem that new security vulnerability can occur when inter-working with the security weakness of each element technology because the internet service based on the object Internet provides a service by integrating various element technologies. In this paper, we propose a user privacy protection model that can securely process user's healthcare information from a third party when delivering healthcare information of users using wearable equipment based on IoT in a mobile environment to a server. The proposed model provides attribute values for each healthcare sensor information so that the user can safely handle, store, and store the healthcare information, thereby managing the privacy of the user in a hierarchical manner. As a result of the performance evaluation, the throughput of IoT device is improved by 10.5% on average and the server overhead is 9.9% lower than that of the existing model.

The primary goal of our study was to investigate the vast transformations of the healthcare sector in Korea during the past half century. Official data reported in the Korean statistical yearbooks and secondary data suggested by previous studies were used for institutional analysis of healthcare environment. Information on hospital released by the Korean Hospital Association was also used for ecological analysis. Institutional analysis: We identified three distinctive eras based primarily on changes in institutional logics, institutional actors, and governance structures : 'professional dominance (1952-1976)', 'government involvement (1977-1999)', and 'coexistence of competing institutional logics (2000-present)'. During the first era, physician association supported by Korean government comprised the primary governance regime. During the second era, the government became a major actor as a regulator and purchaser in health care sector, introducing of the 'mandatory national health insurance'. During the third era, making healthcare system sustainable and providing health care efficiently was overarching goals although it was hard to find a single central logic dominating this period. Ecological analysis: Evidence from the analysis of hospital population suggested that the expansion of the bed capacity was made from different processes, shifting from the ecological process in 1980s to the adaptive process in 1990s. And Korean hospitals had changed following both 'directional process' and 'stabilizing process' over time. Based on our results, we concluded that more studies to compare more organizational populations other than hospitals and to empirically test the effects of institutional changes on organizational changes and vice-versa, need to be conducted.

The ubiquitous healthcare environment is one of the systems that benefit from wireless sensor network. But one of the challenges with wireless sensor network is its high loss rates when transmitting data. Data from the biosensors may not reach the base stations which can result in missing values. This paper proposes the Health Monitor Agent (HMA) to gather data from the base stations, predict missing values, classify symptom patterns into medical conditions, and take appropriate action in case of emergency. This agent is applied in the Ubiquitous Healthcare Environment and uses data from the biosensors and from the patient’s medical history as symptom patterns to recognize medical conditions. In the event of missing data, the HMA uses a predictive algorithm to fill missing values in the symptom patterns before classification. Simulation results show that the predictive algorithm using the HMA makes classification of the symptom patterns more accurate than other methods.

The general sensor network uses bundle method to collect fixed information from sensor node. However, this method is difficult to actively cope with major sensing objects in healthcare environment including status and position change of person and change of surrounding environment. In order to support the healthcare environment, certain information should be provided in accordance with the change of status of person and surrounding circumstance and also must cope with the change of network type by movement of person. This paper analyzes LEACH protocol which guarantees effectiveness of network as it constitutes clusters between Agilla model that is a representative multi agent middle ware and surrounding nodes. Based on the result of this analysis, it suggests LEACH_Mobile protocol which guarantees node mobility that is the weakest point of LEACH protocol. Moreover, it designs mobility agent middleware which supports dynamic function change of node and mobility agent module which supports dynamic function change of mobile node as components of LEACH_Mobile routing module. In addition, it is definitely increase performance which in mobile node of transfer data rate through LEACH_Mobile protocol of simulation result.

As industries converge in recent years, the impact of the use of convergence tools among industries on the security of the organization is increasing. However, organizational members lack the ability to adapt to introduction of new system because they are operating business around existing systems, and thus, security considerations are an environment that will inevitably emerge as a follow-up priority. In this study, we studied cost-effective options for factors that should be considered first in order to establish a security system for small and medium-sized healthcare institutions in the healthcare convergence industry. Specifically, the current legal system was considered and the security status was analyzed through prior research, and the necessary security solution/system was derived from small and medium-sized healthcare institutions. In addition, it analyzed relative priorities for cost-efficient deployment of security systems to those involved in small and medium-sized healthcare institutions in actual business environments and presented measures to establish a overall security.

This study investigates the hospital's figure and the patient's space accrding to the comparative environmental behavior analysis both perception of and stay feature of patients in the hospitals of the Korea and Japan. That study examines to the space and environment of the hospital in the aspect of patient abservation on and hospital geography. Here, the environment was holisticaly understood both the physical environment and the perception & behavior of the patients.

This paper try to provide basic and universal concept of the architectural planning for the barrier-free environment. To accomplish this purpose this study has analyzed inductively the architectural requirements for all kinds of people with disabilities. The Analysis showed a safety, an accessibility and a distinguishment as the concept of architectural planning for the people with disabilities. Based on the findings of the study have been researched the general cases done for the barrier-free architectural environment. As the result, it has been proved that the design concept for the disabled person should be regarded as the basic concept of the general architectural planning.

Patients use the senses all the time, mostly simultaneously. Senses are never turned off even patients in serious condition use some of the senses. Space is the inexhaustible source of stimuli. So far we have thought that it is impossible to come up with a set of rules and guidelines that cover all the possible situations involving senses and when there have been usually no conscious coordination between different sensorial stimuli and the comprehensive perception of space always results from the engagement of combination of senses and other inputs based on knowledge and experience. This study concerns about patients' demand analysis through senses. The reflection of patients' demand to the ward planning can develope the healing environment.
