WBAN (Wirless Body Area Network)은 IEEE 802.15.6에서 정의한 통신 표준으로 인체 내/외부 및 표면에 장착되는 무선 센서 장치들을 통해 의료 및 비의료 서비스를 동시에 제공하는 것을 목표로 한다. 이러한 WBAN은 인체 중심 구성과 네트워크 내부의 이동성 및 네트워크 단위의 이동성을 가지는 특성으로 인해 다수의 WBAN들이 좁은 공간에 공존할 수 있으며, 상호 간섭으로 인해 성능 저하와 같은 문제에 노출된다. 이러한 문제를 해결하기 위해 IEEE 802.15.6에서는 공존 상황을 이동성에 따라 3가지로 세분화 하였으며, 세분화된 각 상황에 적합한 공존성 해결 방안의 가이드라인을 제시하고 있다. 하지만 표준에서는 세분화한 공존 상황을 인지하는 알고리즘과 각 공존성 문제 해결방안의 상세 방안이 결여되어있다. 또한, WBAN의 공존성 문제를 해결하기 위해 제안된 기존의 연구들은 표준에서 정의한 공존상황을 고려하지 않고 있어 추후 표준 기반의 WBAN의 구현시 호환성이 결여된다는 문제점을 가지고 있다. 따라서 WBAN의 공존성 문제 해결에 대한 연구방향의 재조명이 필요한 때 이다. 본 논문에서는 IEEE 802.15.6 표준과 기존의 공존성 문제 해결 방안을 소개하며, 기존 연구의 연구 접근 방법을 분석하고 문제점을 제시한다. 또한, WBAN의 공존성 문제에 대한 새로운 접근 방법과 연구 방향을 제시한다.

This paper presents a 'consequence analysis' for vapor cloud explosions caused by heavy gas leakages from commercially used storage tanks at petrochemical plants. Particularly, this paper emphasizes on evaluating the results of various vapor cloud explosion accidents from Butane storage tanks. Also this paper analyses the impact of variables on the accidents in order to acquire the optimum conditions for variables. $SuperChems^{TM}$ Professional Edition was applied to analyse the impact (If atmospheric and other variables in the situation where vapor cloud continuously disperses from the ground level. Under the assumption that practical operating conditions are selected as a standard condition, and Butane leaks from the storage tank for 15 minutes, the results show that the maximum distance of LFL (Lower Flammable Limit) was 52 meters and overpressure by the vapor cloud explosion was 1 psi at 128.2 meters. It is observed that the impact of the variables on accidental Butane storage tank leakage mainly varied upon atmospheric stability, wind velocity, pipe line size, visible length, etc., and changes in the simulation result occurred as the variables varied. The maximum distance of the LFL (Lower Flammable Limit) increased as the visible length became shorter, the size of the leak became larger, the wind velocity was decreased, and the climatic conditions became more stable. Thus, by analysing the variables that influence the simulation results of explosions of Butane storage tanks containing heavy gases, I am presenting the most appropriate method for 'consequence analysis' and the selection of standards for suitable values of variables, to obtain the most optimal conditions for the best results.

Exchanging personal health information(PHI) is an essential process of healthcare services using information and communication technology. But the process have the inherent risk of information disclosure, so the PHI should be protected to ensure the reliability of healthcare services. In this paper, we designed encryption module for wearable personal health devices(PHD). A main goal is to guarantee that the real-time encoded and transmitted PHI cannot be allowed to be read, revised and utilized without user's permission. To achieve this, encryption algorithms as DES and 3DES were implemented in modules operating in Telos Rev B(16bit RISC, 8Mhz). And the experiments were performed in order to evaluate the performance of encryption and decryption using vital-sign measured by PHD. As experimental results, an block encryption was measured the followings: DES required 1.802 ms and 3DES required 6.683 ms. Also, we verified the interoperability among heterogeneous devices by testing that the encrypted data in Telos could be decoded in other machines without errors. In conclusion, the encryption module is the method that a PHD user is given the powerful right to decide for authority of accessing his PHI, so it is expected to contribute the trusted healthcare service distribution.

IT technology of U-healthcare system is being grafted onto medical services and the use of U-healthcare system are extending steadily. However, in case of patients using Implantable Medical Device (IMD) in U-healthcare system, patients' privacy protection and safe access to system recently has emerged as a major issue. This paper proposes a patients' privacy protection protocol to prevent any illegal accesses from third parties as state value and action value are synchronized after patients' information virtualization. The proposed protocol can limit the access range of patients' information according to authentication information of hospitals, doctors, nurses, and pharmacies registered in the U-healthcare server. Additionally, this protocol can increase management efficiency for patients' privacy by synchronizing state values and action values only for approved information and, by instituting this process, third parties cannot easily access patients' information.
