Objects:The purpose of this study is to investigate the clinical effect of the Dong-Si acupuncture treatment at the acute ankle sprain.Methods:This study was carried out on the 43 patients who had been treated at Conmaul oriental hospital from June 1st, 2001 to July 30th, 2001.We divided these patients into 2 groups. The GroupⅠ was practiced with the Dong-Si acupuncture treatment and GroupⅡ was practiced with the painful point acupuncture treatment.We investigated visual analogue scale(VAS) score after treatment.Results and Conclusions:The VAS score of GroupⅠ was statistically lower than GroupⅡ after 1st.and 2nd treatment.So we may conclude that the Dong-Si acupuncture treatment and rehabilitation is recommendable at early stage of ankle sprain.

본 논문에서는 모바일핸드셋을 이용하여 차량의 상태를 정검/감시할 수 있는 자동차 자가진단 시스템에 대하여 연구경과와 구현결과를 기술한다. 우리나라에서는 2005년도부터 자동차진단 시스템 표준인 OBD(On Board Diagnostics)-Ⅱ 시스템 장착이 의무화 됨에따라, 개인도 OBD 스캐너만 있으면 차량의 상태를 진단할 수 있게 되었다. 그러나 고가의 전문정비용 스캐너 이외에는 아직까지 개인이 간편하게 사용할만한 저가의 스캐너는 전무한 실정이다. 이러한 배경을 바탕으로 OBD-Ⅱ 표준을 기반으로 한 프로토콜 변환기와 개인소지 휴대폰만으로 자동차의 진단이 가능한 자동차 자기진단시스템을 개발하게 되었으며, 여기에 필요한 사용자 인터페이스는 한국의 모바일 표준 플랫폼인 WIPI에서 구현하였다.

Purpose: Nicotinic acetylcholine receptors (nAChRs), which mediate excitatory neurotransmission, are known to participate in various neurophysiological functions. Severe losses of nAChRs have been noted in Alzheimer's and Parkinson's diseases. Therefore, noninvasive and quantitative imaging of nAChRs would offer a better understanding on the function of these receptors. In this study, 2-[^18F]fluoro-A85380 ([^18F]1), an α_4β_2 nAChRs radioligand, was prepared using one HPLC purification and evaluated in mouse brain, and the results were compared with those in the literature. Materials and Methods: [^18F]1 was prepared by [^18F]fluorination of the iodo precursor followed by acidic deprotection and then purified by HPLC. Tissue distribution studies were performed in mouse brain at the indicated time points adn the result was expressed as %ID/g, Inhibition studies were also carried out with pretreatment of various ligands. Results: One HPLC purification method gave the desired product in 15-20% radiochemical yield and with high specific activity (38-55 GBq/μmol). Tissue distribution studies showed that [^18F]1 specifically labeled nAChRs in mouse brain with a high thalamus to cerebellum uptake ratio (13.8 at 90 min). Inhibition studies demonstrated selective binding of [^18F]1 to nAChRs, blocking the uptake of the [^18F]1 in nAChR-rich regions by selective ligands such as cytisine and nicotine which are well-known nAChRs agonists. Conclusion: This study demonstrated that the [^18F]1 produced by the method using one HPLC purification gave the results similar to those reported in the literature. Therefore, this synthetic method can be readily applied to the routine preparation of [^18F]1, a PET radioligand for α_4β_2 nAChRs imaging. (Korean J Nucl Med 2002;36;261-70)

Purpose: This study was supplying basic data for nursing intervention plan to improve health related to task by examining whether nurses' burnout is related with work stress, job satisfaction, and organizational commitment in hospitals. Method: The subjects were 205 nurses, working at the hospitals in the D metropolitan city & K city in Chungnam province from July 9th to July 23rd, 2004 by a structured questionnaire. The data were analyzed using descriptive statistics, Pearson correlation coefficient, and stepwise multiple regression. Result: The correlated factors of burnout of the nurses in the hospitals were work stress(r=.450, p=.000), job satisfaction(r=-.660, p=.000), and organizational commitment(r=-.653, p=.000). The most powerful predictor of burnout of the nurses in hospitals was influenced on job satisfaction(45.3%). A combination of job satisfaction, organizational commitment(6.6%), work stress(6.2%), and age(1.5%) accounted for 59.6% of the variance in burnout of the nurses in hospitals. Conclusion: The results show that nurses' burnout related to job satisfaction, organizational commitment, work stress, and age in hospitals. It suggested that goal of decreasing nurses' burnout in hospitals should be helped them lower work stress, raiser job satisfaction and organizational commitment.
