최근 전세계적으로 헬스케어 산업에 대한 관심이 부각되고 있고, 그 중에서도 헬스케어 데이터를 딥러닝 등의 기계학습으로 분석하는 의료 AI 산업이 급속히 주목을 받고 있다. 기계학습 기법의 특성상 의료 AI 개발을 위해서는 헬스케어 빅데이터가 반드시 필요하다. 하지만, 현재 대부분의 헬스케어 데이터들은 비표준화된 형태로 서로 다른 방법으로 생성되고 있어, 이를 통합하고 분석하는 데 많은 어려움을 겪고 있다. 본 고에서는 건강과 관련된 헬스케어 데이터들의 종류와 특징을 간단히 정리하고, 해당 데이터들을 통합하고 분석하기 위해 필요한 국제 표준을 소개하고자 한다.

Molecular computing using programmable nucleic acids has been attracting attention for use in autonomous sensing systems and information processing systems by interacting with a biological environment. Here, we introduce a rule-based in vitro molecular classification system that can classify disease patterns using several microRNA (miRNA) markers via the assembly of programmed DNA strands. The classification rules were derived by analyzing large-scale miRNA expression data obtained from a public database, and the identified rules were converted into DNA sequences. Classification was performed via the detection of miRNA markers in the rules. The classification results were reported as a binary output pattern according to their hybridization to the rule sequences, which can be conveniently visualized using gold nanoparticle aggregation. Our results demonstrate the utility of in vitro molecular classification by illustrating one of the ways in which molecular computing can be used in future biological and medical applications.

The roles of freight forwarders as intermediaries continue to expand and become significant in international logistics. Purchasing negotiation is considered an important business process for freight forwarders and achieving a successful negotiation outcome should help forwarders to manage their business more effectively. This study used the analytical hierarchy process (AHP) approach to identify the critical factors for successful purchasing negotiation for freight forwarders in Korea. A three-level AHP structure was constructed to examine the successful purchasing negotiation. The findings indicate that information (specifically quality of information) is the most critical factor for a successful negotiation outcome for freight forwarders. This result turned out to be the same as the result found from the literature review. Literature review also indicated information as the most important factor.

In this paper, the impact of channel sensing methods to IEEE 802.15.4 under the interference of IEEE 802.11b are analyzed. Two different channel sensing methods, energy detection and carrier sense, are considered. An average transmission delay, a throughput, and a power drain rate are used as performance measures. Those performance measures of IEEE 802.15.4 under the interference of IEEE 802.11b are analyzed mathematically. The simulation results are shown to validate the analytic results.
