HITSP(Healthcare Information Technology Standards Panel)은 헬스 케어 관련 산업의 상호 운용성을 위해 일반적으로 수용되고 유용한 표준들을 선별하여 표준 세트를 제공하는 것을 목적으로 한다. HITSP에서는 평생전자건강진료정보(EHR, Electronic Health Record)의 활성화를 위해 첫 번째 해결해야 할 영역으로 검사실 결과 정보 교류를 정하였다. 이에 본 논문에서는 검사실 결과 정보 교류를 위한 방법으로 HITSP에서 제시하는 HL7 버전 2.x 메시지와 CDA 방법 중 인증(authentication) 처리가 가능하고 영속성(persistence)이 있는 CDA 방법을 선택하였다. 또한 CDA를 작성하고 처리하는 방법을 제시하고, 더 나아가 평생전자건강진료정보(EHR)를 위해 CDA를 적용하여 검사실 결과 정보를 교류하여 보았다. 이에 병원과 EHR 시스템의 상호 운용성이 높아져 진료 과정의 효율성을 높일 수 있었고 환자와 의료진에게 양질의 검사 결과 정보를 제공할 수 있었다.

We develop an intelligent information system in a multilayer electronic supply chain network. Using the internet for supply chain management (SCM) is a key interest for contemporary managers and researchers. It has been realized that the internet can facilitate SCM by making real time information available and enabling collaboration between trading partners. Here, we propose a multi-agent system to analyze the performance of the elements of a supply network based on the attributes of the information flow. Each layer consists of elements which are differentiated by their performance throughout the supply network. The proposed agents measure and record the performance flow of elements considering their web interactions for a dynamic route selection. A dynamic programming approach is applied to determine the optimal route for a customer in the end-user layer.

사물인터넷은 4차 산업혁명의 중요한 요소 기술로서 역할을 담당하고 있다. 본 연구는 최근 IT 기술을 적용한 지능형 자동차를 개발하고 있으며, 지능형 자동차에 대한 개발이 활발하게 이루어지면서 그에 대한 네트워크 데이터 통신이 가능하게 된 시점에 있다. 하지만 외부에서 네트워크에 침입하여 보안을 위협할 수 있으며 보안이 아직 미약한 단계이기에 그에 따른 보안솔루션이 필요하다. 본 논문에서는 지능형 자동차에 보안 문제가 발생하지 않고 보안성을 높이기 위해서 블록체인의 기술을 적용하고 사용자의 생체정보를 이용하여 생체인증 기법을 제안하고 향후 지속해서 연구하고자 한다.

In this paper, a novel dynamic available transfer capability (DATC) has been computed for real time applications using three different intelligent techniques viz. i) back propagation algorithm (BPA), ii) radial basis function (RBF), and iii) adaptive neuro fuzzy inference system (ANFIS) for the first time. The conventional method of DATC is tedious and time consuming. DATC is concerned with calculating the maximum increase in point to point transfer such that the transient response remains stable and viable. The ATC information is to be continuously updated in real time and made available to market participants through an internet based Open Access Same time Information System (OASIS). The independent system operator (ISO) evaluates the transaction in real time on the basis of DATC information. The dynamic contingency screening method [1] has been utilized and critical contingencies are selected for the computation of DATC using the energy function based potential energy boundary surface (PEBS) method. The PEBS based DATC has been utilized to generate patterns for the intelligent techniques. The three different intelligent methods are tested on New England 68-bus 16 machine and 39-bus 10 machine systems and results are compared with the conventional PEBS method.

Query language has been widely used as a convenient tool to obtain information from a database. However, users demand more intelligent query processing systems that can understand the intent of an imprecise query and provide additional useful information as well as exact answers. This paper introduces a meta-database and presents a query processing mechanism that supports a variety of intelligent queries in a consistent and integrated way. The meta-database extracts data abstraction knowledge from an underlying database on the basis of a multilevel knowledge representation framework KAH. In cooperation with the underlying database, the meta-database supports four types of intelligent queries that provide approximately or conceptually equal answers as well as exact ones.

A modalized Łukasiewicz three-valued propositional logic will be proposed in this paper which there are three modalities [t]; [m]; [f] to represent the three values t; m; f; respectively. And a Gentzen-typed deduction system will be given so that the the system is sound and complete with respect to the Łukasiewicz three-valued semantics Ł$_3$, which are given in soundness theorem and completeness theorem.

Significant progress has been made recently in detection of highly sensitive volatile organic compounds (VOCs) using chemical sensors. Combined with the progress in design of micro sensors array and electronic nose systems, these advances enable new applications for detection of extremely low concentrations of breath-related VOCs. State of the art detection technology in turn enables commercial sensor systems for health care applications, with high detection sensitivity and small size, weight and power consumption characteristics. We have been developing an intelligent electronic nose system for detection of VOCs for healthcare breath analysis applications. This paper reviews our contribution to monitoring of respiratory diseases and to diabetic monitoring using an intelligent electronic nose system for detection of low concentration VOCs using breath analysis techniques.

Recently, the importance of intelligent personalized services is increasing in the era of the 4th Industrial Revolution. In this paper, we proposes design and implementation of the agent recruitment service system for the intelligent headhunting service. The proposed service system has designed and implemented an intelligent service system to efficiently recruit and manage applicants(job seekers). In addition, we develops the modules that can analyze the profile information of the applicant(job seeker), and implement the algorithm to predict the talent verification and analyze the talent type. The proposed service system is expected to contribute to designing the innovative and new service models for the intelligent agent recruitment service system.
