An invesitigation on power consumption of a mobile multimedia system using OFDM and MDVS technique is reported here. Analysis and simulation are performed to find the significances of proposed Microscopic Dynamic Voltage Scaling(MDVS) tehnique[4] on digital processor in terms of power saving. A study is also made to show power reduction in mobile multimedia system by incorporating OFDM modulation scheme in RF front-end. Finally, overall power consumption by functionally distinguished blocks ie. RF front-end, digital processor and human interface unit is shown here. Total power consumption is 8.2W for 2Mbps SD-quality WCDMA multimedia video service - the power consumption of digital processor is 3.9W(48%), the power consumption of RF front-end is 3.2W (36%), and the power consumption of interface is 1.8W(16%). Power saving of applying purposed MDVS technique is 35% in digital processor, and power saving of OFDM technique is 10-12dB in RF front-end.

The pre-existing medical treatment was done in person between doctors and patients. EMR (Electronic Medical Record) System computerizing medical history of patients has been proceed and has raised concerns in terms of violation of human right for private information. Which integrates "Identification information" containing patients' personal details as well as "Medical records" such as the medical history of patients and computerizes all the records processed in hospital. Therefore, all medical information should be protected from misuse and abuse since it is very important for every patient. Particularly the right to privacy of medical record for each patient should be surely secured. Medical record means what doctors put down during the medical examination of patients. In this paper, we applies fingerprint identification to EMR system login to raise the quality of personal identification when user access to EMR System. The system implemented in this paper consists of embedded module to carry out fingerprint identification, web server and web site. Existing carries out it in client. And the confidence of hospital service is improved because login is forbidden without fingerprint identification success.

The purpose of this study was to investigate the differences of evaluative criteria and brand preferences by clothing purchasing motivations of Chinese female consumers. Data were obtained from 350 Chinese women in the 20's and 30's who were living in Shanghi, China. Data were analyzed by factor analysis, ANOVA, Duncan test, cluster analysis, and descriptive statistics using SPSS WIN 12.0. The results of this study were as follows. The clothing purchasing motivations of consumers were classified into 'hedonic,' 'utilitarian,' and 'economic' motivation. The evaluative criteria of clothing were classified into 'aesthetic/quality,' 'service/care,' and 'social status symbol' evaluative criteria. Chinese female consumers were divided into four groups by cluster analysis of clothing purchasing motivation; economic, practical hedonic, utilitarian, and inactive groups. There were significant differences in evaluative criteria of clothing, brand preference of foreign brand and Korean brand, and purchase intention among four groups. Practical hedonic and economic groups showed the highest means of evaluative criteria of clothing, foreign brand, Korea brand, and purchase intention of Korean apparel brand. This study provides implications into Korean fashion marketers for developing marketing strategies in China.

의료영상의 프랙탈 부호화 방법은 영상을 반복 변환시스템인 IFS(iterated function system)를 구성해야하고, 이를 위해 영상영역을 레인지 영역으로 분할하고 각 레인지블록에 대해 탐색하게 될 도메인 블록에서 가장 닮은 최적의 블록을 찾는다. 이때, 결정되는 변환계수 값과 좌표의 정보를 프랙탈 계수로 전송한다. 본 연구에서는 이러한 프랙탈 계수들을 확률분포를 추출할 수 있는 양자화기를 통해 양자화 하여 비트를 할당하였다. IFS를 구성하는 부호화과정에서 가변크기 블록방법을 사용하여 부호화시간을 단축하고 압축률을 향상시키는 방법을 제시하였다. 추후 프랙탈 부호화과정에서 화질을 최상으로 유지하면서 부호화시간을 단축시키고 압축률을 높이는 연구가 더 진행되어야 할 것 으로 본다.

The Chuna(推拿) in Korea has been developed since 1990's. Korean Chuna which is the only one manual therapy done by medical doctor is riched by absorbing other nation's manual therapy like Chinese Tuina(中國推拿) and Chiropractic therapy of U.S.A. So, We find that Korean Chuna's peculiarity and development by comparing Chinese Tuina, Chiropractic of U.S.A and Japanese manual therapy which influenced establishment of Korean Chuna. We compared each manual therapy's history, development, diagnosis, correction and treatment of human body, frequently contacting disease and medical service of the present state. Korean Chuna has absorbed other nation's manual therapy and advantage of preserving muscle-skeleton and spinal disorder disease. But, for more prosperity, it needs union of various conception and diagnosis and more research and application to more various disease, for example in internal medicine, gynecology or pediatry and founding system as regular academic work inside the college the possibility which objection and it will practice more completeness. And as one of specialty apprentice doctor subject inside the hospital, the possibility of raising a quality improvement of study and research environment.

The questionnaire was distributed online to each hospital, and approximately five or more questionnaires were hardcopies. This research was conducted over less than six months. The data obtained were processed via excel files, then checked for conformity, and analyzed by partial least square (PLS) software with descriptive statistics. This study uses path analysis, which that is structural equation modeling (SEM). The findings show that management style, decentralization, and budgetary participation significantly affect management accounting systems. However, management style and budgetary participation did not influence managerial performance. Finally, the findings indicate that management accounting systems are positively affected by managerial performance.
