This study is an exploratory research on smart healthcare services, specifically focusing on a multi-channel CCR based healthcare service system. The study examines the overview and operational principles of the service system, highlighting the significance of user communication and its role in the system's functionality. Furthermore, the study investigates the impact of service quality on user satisfaction and intention to continue using the service. To achieve this, a structural equation modeling(SEM) analysis was conducted with a sample of 188 users who owned and utilized healthcare devices and apps. The results indicate that service quality dimensions (reliability, responsiveness, empathy, assurance, and tangibility) all had a positive influence on user satisfaction. Additionally, user satisfaction was found to have a significant impact on intention to continue using the service. The findings of this study contribute to exploring the effectiveness and potential value of CCR-based smart healthcare services. It was also provided insights for the future development of smart healthcare systems that offer accurate health information and personalized services for individual health management and prevention.

인터넷쇼핑몰은 전통적 유통경로에 비해 많은 장점을 지니고 있음에도 많은 네티즌 (Netizen)들올 만족시키지 못하고 있는데 그 이유중 하나는 머천다이징 전략의 실패에 기인 한다 인터넷쇼핑올 운영자률은 어떤 종류의 제품 서비스들이 인터넷쇼핑몰 판매에 적합 한가에 대한 많은 관심을 가지고 있지만 여기에 대한 기존의 연구가 부족한 실정이다. 본 연구에서는 인터넷쇼핑몰의 만족 결정요인 가운데 하나인 머천다이징 만족에 영향을 미치는 요인들에 대하여 알아보았다. 실종연구 결과는 다음과 같다. 먼저, 제품믹스의 깊이는 머천다이징에 대한 만족에 영향을 주지만, 폭은 영향이 없는 것으 로 나타났으며, 머천다이징에서 '비트-기초 제품'의 비중이 높을수록 그리고 제품의 탐색성이 높올수록 머천다이징에 대한 만족이 높은 것으로 나타났다. 또한 제품이미지나 명성이 높을수 록 그러고 정보가 풍부한 제품일수록 머천다이징 만족이 높은 것으로 나타났다.

Modern embedded system employs a hybrid architecture which contains a general micro processor and reconfigurable devices such as FPGAS to retain flexibility and to meet timing constraints. It is a hard and important problem for embedded system designers to explore and find a right system configuration, which is known as design space exploration (DSE). With DES, it is possible to predict a final system configuration during the design phase before physical implementation. In this paper, we implement a timing analysis simulator for a DSE on a hybrid embedded system. The simulator, integrating exiting timing analysis tools for hardware and software, is designed by extending Y-chart approach, which allows quantitative performance analysis by varying design parameters. This timing analysis simulator is expected to reduce design time and costs and be used as a core module of a DSE for a hybrid embedded system.

This study was to explore the relationships between convention mobile applications, and convention participants' satisfaction and loyalty. Recently mobile applications by using smart-phone have been utilized to provide relevant information and contents, Similarly, convention industry utilize mobile application to provide convention program, speakers, and other information and contents, However, only few research has been conducted to investigate convention mobile application characteristics and benefits. This study provides the results of convention mobile application characteristics and its impacts on participants' satisfaction and loyalty. Among convention mobile application characteristics, conveniency and information are important factors to enhance convention participants' satisfaction and loyalty. More discussion and implication is provided in the conclusion section.

The purpose of this study was to identify the improvement plan of Korea Network for Occupations and Workers(KNOW) in terms of the information quality and usefulness for undergraduate students.'Homework of occupational information exploration'as research instrument was assigned to the engineering students taking career courses at KoreaTech in Chungnam province, Korea. Data was collected from two-hundred sixty six college students. The main results were as follows: The percentage of awareness of KNOW was very low(7.5%), but the mean of preference(73.5) and usefulness of career readiness(70.6) of KNOW were likely to be high. The information quality of KNOW was analysed in terms of both menu bar and evaluative components. In menu bar, the highest mean of information quality was'wage, job satisfaction, and job outlook'menu bar(71.7). On the other hand'task information on the job'had the lowest mean. In evaluative component, the highest mean of information quality was understandability(73.4), whereas the completeness was at the bottom(63.7). These results implied that the KNOW has the usefulness for engineering students to explore the occupational information and to make ready for career. Nevertheless, it is needed to publicize KNOW and to redeem menu bar and contents for the improvement of this online system.

본 논문에서는 최적화 문제를 해결하는 기법의 하나인 유전자 알고리즘을 이용하여 모든 노드를 탐색하여 최적의 경로를 도출하는 최적화 경로 탐색 알고리즘을 제안한다. 경로를 도출하기 위해 중간 경로 노드로부터 출발지 노드 및 도착지 노드까지의 거리를 측정하여 개체를 생성한다. 출력 노드들을 도출하기 위해 생성된 개체를 적합도 함수에 적용하여 적합도를 계산한다. 계산된 적합도 값에 따라 교배를 할 노드 및 교배 지점(비트단위)을 선택한다. 선택되어진 교배와 교배 지점을 이용하여 개체들을 교배한다. 교배를 통해 새로운 개체를 생성한다. 새로운 개체가 적합도 조건(이전 개체 중 최대값 $^*\;2$)에 만족한다면 출력 노드로 도출하고, 다음 출력 노드를 도출할 때의 출발지 노드로 선택되어진다. 이러한 과정을 반복하여 모든 출력 노드를 도출한다. 제안된 방법을 실험한 결과, 순차 방식과 난수를 이용한 경우보다 제안된 방법이 효율적인 것을 확인하였다.

In this paper, we proposed new algorithm that improves the acquisition performance of the PN code searcher used in DS-CDMA systems. Using the mean deviation computed from the correlator output of the PN code searcher, it is possible to estimate received channel environment. To satisfy the required acquisition performance in estimated channel environment, the PN code searcher changes the correlator tap size adaptively. Proposed algorithm shows improved performance compared with conventional algorithm using the fixed correlator tap size.

멀티미디어 데이터 처리나 암호화 알고리즘과 같은 계산양이 많고 빠른 시간 안에 처리되어야하는 어플리케이션들을 처리하기 위하여 재구성 가능한 논리소자와 내장형 마이크로 프로세서등이 하나의 칩에 통합된 재구성 가능한 SoC가 폭넓게 활용되고 있다. 이러한 컴퓨팅 환경의 시장적응성을 높이기위해서는 프로토타입을 제작하기 전에 설계변수에 따른 성능수치를 이미 예측하여 최소의 비용으로 시스템의 수행 시간 및 자원제약사향을 만족할 수 있는 구조를 찾아내는 것이 필수적이다. 본 논문에서는 Y-chart 설계 방법의 기본 개념을 재구성 가능한 SoC에 적용가능하도록 확장하여, 시스템 수준의 설계공간 탐색 도구를 개발하였다. 구현된 설계 공간 탐색을 통한 시뮬레이션 결과는 시스템 설계자들에게 실제 포로토타입을 구축하지 않고 최적의 설계변수를 결정할 수 있게 하여 설계시간과 설계비용을 현저하게 줄여줄 것으로 기대된다.
