본 논문에서는 적응화된 콘텐츠 서비스를 위해 콘텐츠 적응화 시스템에서 효율적으로 사용자 프로파일을 교환하는 방법을 제안한다. 사용자에게 적응화된 콘텐츠를 제공하기 위해 프로파일들은 콘텐츠 적응화 시스템의 디바이스들 간에 지속적으로 교환된다. 또한 프로파일들은 주기적, 비주기적, 이벤트, 요청 및 응답에 따라 교환되어야 한다. 따라서 많은 네트워크 트랙픽이 발생하며 컴퓨팅 파워를 필요로 한다. 이와 같은 문제점들을 해결하기 위한 프로파일 교환 연구가 필요하다. 효율적인 프로파일 교환을 위하여 콘텐츠 적응화 시스템에서 프로파일 생성 정보, 교환 정보, 교환 형태 등을 분석하고 분석된 프로파일 정보들을 이용하여 프로파일 교환 절차를 정의하였다. 또한 프로파일 처리 시간을 줄이는 프로파일 구성 정보 제공 방법과 프로파일 전송횟수를 줄이는 사용자 설정 값 방법을 제안하였다. 성능 평가 결과 프로파일 구성정보 제공 방법은 프로파일 처리 시간을 7%로 단축시켰으며, 사용자 설정 방법은 프로파일 전송횟수를 줄여 프로파일 교환에 효율적이었다. In this paper, we propose the effective exchange-method of a user profile for adapted contents services in the contents adaptation system. The profiles continuously exchange among the devices of contents adaption system for providing the adapted contents to a user. The profile should be also exchanged according to periodic, aperiodic, event, request and response. Consequently, a lot of network traffic occur and computing power require. Solving theses problem, the profile exchange research needs. we analyze creation information, exchange information, and exchange form of the profile information in contents adaptation system for effective profile exchange and define exchange procedure of the profile using the analyzed profile information. we also propose providing method of the profile configured information for decreasing profile processing time and user setting method for decreasing the number of profile transmission. As a result of performance evaluation, providing method of the profile configured information reduce 7% processing time and user setting method decrease the number of profile transmission are effective to exchange the profile.

주요 IT 벤더들은 클라우드 컴퓨팅 기술을 이용하여 설치과정 생략, 운용비용 절감, 서비스품질 등에 중점을 두어 대규모 콘텐츠 서비스를 제공하고 있다. 반면에, 대규모 콘텐츠 데이터의 가공, 분석을 수행하는 데이터 처리 프로세스는 처리 시간의 단축을 위한 방법론이 요구되고 있다. 이에 본 논문에서는 클라우드 환경에서 대규모 콘텐츠를 위한 효율적인 자원처리 기법(Efficient_Cloud_Processing_Scheme : ECPS)을 제안한다. 제안한 기법은 리소스 확장 방안을 CPU 및 스토리지 등의 인프라스트럭처 단계에서 설계한다. 대규모 콘텐츠에 대한 자원 할당 방안을 Hadoop 플랫폼 기반의 MapReduce 프로그래밍 기법과 데이터마이닝 분야에서 숨겨진 패턴을 탐지하는데 사용되는 연관규칙을 이용하여 제시한다. 기존 설정값으로 자원을 할당하여 운용 되는 환경과 비교하여 ECPS기법을 적용한 결과, 제안 기법이 20% 이상의 성능 및 속도가 향상되었음을 확인하였다. Major IT vendors expect that cloud computing technology makes it possible to reduce the contents service cycle, speed up application deployment and skip the installation process, reducing operational costs, proactive management etc. However, cloud computing environment for massive content service solutions requires high-performance data processing to reduce the time of data processing and analysis. In this study, Efficient_Cloud_Processing_Scheme(ECPS) is proposed for allocation of resources for massive content services. For high-performance services, optimized resource allocation plan is presented using MapReduce programming techniques and association rules that is used to detect hidden patterns in data mining, based on levels of Hadoop platform(Infrastructure as a service). The proposed ECPS has brought more than 20% improvement in performance and speed compared to the traditional methods.

Objectives : The mechanical properties of Korean electric cupping systems are studied via experimental measurements. The study aimed at establishing the fundamentals of industrialization and systemization of oriental medicine device industry, as well as improving the quality of life for many Koreans. Methods : We reviewed the studies on traditional cupping as well as modern one to fine necessary factors for electric cupping systems. To characterize the mechanical properties of Korean electric cupping systems, we measured the pressure characteristics of commercially available electric cupping system by using an automatic pressure acquisition system and a standard cup. The pumping capability was checked at 40 seconds, and the stability of the suction cup was checked at 600 seconds. We also acquired the noise level of each system in clinical setting. To check the portability of each system, we also measured its physical dimensions. We scrutinized system manuals provided by the system manufacturers. Results : It took less than 5 second to reach the pressure if the connection between the air hose and the vacuum valve of the cupping system was secure. Pressure diminished to no more than 10% for 600s for all systems. Noise levels were 55~70 dB. Increase in pressure was too fast to control for a designated vacuum level except for one product. Conclusions : The Pumping ability of the systems is impressive and reliable. Pressure retention ability of each cup is quite reliable and reproducible. Therefore, their mechanical performances were worthy of recommendation. Some of them had noise level higher than 60 dB and they were bothersome. It was also suggested that the control for low to middle pressure needed to be accomplished by the cupping system.

Objective: This research aimed to understand patients' perceptions of Korean medicine treatment for osteoporosis in a clinical trial setting. Methods: Ten patients participating in a clinical trial of a herbal medicine drug for osteoporosis were invited to an interview. Data were collected by in-depth interviews and patient observations. This qualitative study adopted the case study research method, and within-case and cross-case analyses were conducted. Results: A model of the patients' osteoporosis management planning was derived from the study. The results showed that the patients' perceptions of osteoporosis were derived from their knowledge and experience during diagnosis and treatment of the condition. Two groups of patients were recognized: those who overlooked the importance of osteoporosis and those who recognized the importance of osteoporosis. Before making treatment decisions about osteoporosis, the patients evaluated the treatment options and weighed the advantages and disadvantages of each option. When evaluating their treatment, the patients combined their knowledge and experience of Korean and western medicine treatments. Their experience of participating in the clinical trial influenced the management planning of osteoporosis. Two major reasons for low compliance with osteoporosis treatment were ignorance of the disease and insufficient information provided by doctors. Conclusion: The results of this qualitative study pointed to four strategies that could be employed to improve accessibility to Korean medicine treatment for osteoporosis: the dissemination of comprehensive information on osteoporosis in the clinic and mass media, promotion of Korean medicine therapies for osteoporosis, management of clinical trial participants, and insurance coverage for Korean medicine.
