우리나라 여러 기관에 근무하는 응급구조사들의 응급처치 시행내용과 관련요인을 파악코자 2008년 6월 대한응급구조사협회에서 주최하는 보수교육에 참여한 자중 80명과 특정지역 119 구급대 소속 53명, 총 133명에게 설문조사를 시행하였다. 본 연구 결과 조사대상 응급구조사들의 응급처치 내용별 빈도를 보면 생체징후감시가 가장 많았고 그다음이 산소포화도 측정, 산소투여, 지혈 및 창상처치, 심전도 감시 순으로 많았다. 응급처치 23개 전체항목 시행횟수에 통계적으로 유의한 관련요인은 거주지 구분과 자격종류이었으며 단일 응급처치항목으로서 정맥로 연결시행횟수의 유의한 관련요인은 대상자의 성별, 정맥로 연결에 대한 중요성 인식도이었고 근무 기관의 종류도 경계역에서 유의한 관련요인으로 선정되었다. 심전도 감시 시행횟수의 유의한 관련요인은 대상자의 성별로 남성보다 여성이 시행 횟수가 많았다. 따라서 응급구조사들의 응급처치 시행횟수를 상황에 따라 적절하게 유지케 하기 위해서는 응급구조사들의 응급처치에 대한 중요성 인식도, 응급처치에 대한 자신감 등을 향상 시킬 수 있는 노력이 이루어져야 하며 특히 남성 응급구조사, 2급 응급구조사, 중소도시에 거주하는 응급구조사들에 대한 관리 노력이 이루어져야 할 것으로 사료된다. 또한 응급구조사들의 응급처치 시행에 대한 적절성 평가와 더불어 응급구조사 역할 발전에 대한 지속적인 연구가 이루어져야 한다고 사료된다. Objectives: A study was conducted by analysing the contents and frequency of emergency treatment practiced by emergency medical technicians(EMTs) in emergency situations and contains related factors. Methods: The study subjects included 80 EMTs who participated in ongoing education classes during the period from June 25th to June 26th, 2008. the survey included 53 EMTs employed within 119 first aid teams in fire stations in both a metropolitan city and a medium-sized city. From the survey results relation between frequency of emergency treatment and subjects characteristics explored statistically including t-test, X2 test, Pearson correlation and finally stepwise multiple regression. Results: The most frequent procedure by EMTs checking vital signs. The statistically significant related factors overall of the 23 items of emergency treatment frequency was the working area and the grading of EMT certification. In contrast, significant related factors with frequency of IV linkage were found to be the subjects gender, institution employed and the importance of recognizing the item. The statistically significant related factors of that of ECG monitoring was the gender of respondents. Conclusions: To keep the appropriate frequency of emergency treatment by EMT, active efforts to promote their individual importance and confidence cognition are necessary, especially towards males and persons who have 2<SUP>nd</SUP> class certification. Moreover, EMTs who work in small cities must be supported.

본 연구에서는 3 메가픽셀, 2.5배 줌 카메라폰 모듈용 비구면 유리렌즈 개발을 목적으로 실험계획법(DOE)을 적용하여 성형용 초경 코어의 연삭가공조건을 구하고, 이를 활용하여 비구면 Glass렌즈 성형용 초경합금(WC) 코어를 초정밀 연삭가공을 수행하였다. 또한 가공된 성형용 코어의 가공면 위에 이온증착법으로 다이아몬드상 탄소(Diamond-Like Carbon; DLC) 코팅을 수행하여 DLC 코팅이 성형용 코어의 형상정도(PV)와 표면조도(Ra)에 미치는 영향을 평가하였으며, 비구면 Glass렌즈를 동일한 조건에서 성형하여 성형렌즈의 광학적 특성을 비교하여 성형용 코어면의 DLC 코팅 효과에 대하여 검토하였다. In this research, the optimal grinding condition has been obtained by design of experiment (DOE) fur the development of aspheric lens for the 3 Mega Pixel, 2.5x optical zoom camera-phone module. Also, the tungsten carbide (WC) mold was processed by the method of ultra precision grinding under this optimal grinding condition. The influence of diamond-liked carbon (DLC) coating on form accuracy (PV) and surface roughness (Ra) of the mold was evaluated through measurements after DCL coating using ion plating on the ground mold. Also, aspheric glass lenses were molded, some before DLC coating of the mold and some after the DLC coating. The optical characteristics of each sample, molded by the different molds, were compared with each other.

N/A Objectives : Oriental pear was used as treating disorder of heart and blood circulation in oriental medicine. This study was designed to investigate that pear pectin, pear phenolic compound effects on cardiovascular system as regional cerebral blood flow(rCBF), mean arterial blood pressure(MAP), heart rate, cardiac contractile force. Methods : The experiments were performed on Sprague Dawley rats. 2K1C hypertension model was prepared by constricting the left renal artery with a sliver clip. Apple pectin, pear pectin and pear phenolic compound solutions were administrated via femoral vein for Sweeks, a day`s interval. Animals were divided into four groups, administration of apple pectin(AP1, pear pectin(PP) and pear phenolic compound( PPC ). Results : The results are that KBF was significantly increased at lmglkg in PPC group. The MAP was significantly decreased at l0㎍/kg in apple pectin, at l0㎍/kg, 100㎍/kg in pear pecitn than before adminstration, but increased at 1 m p d k g in pear phenolic compound. There was no significant effects in heart rate. Cardiac contractile force was significantly increased a at l0㎍/kg, l00㎍/kg, lmg/kg in pear phenolic compound. Conclusions : These results suggests that pear phenolic compound and pear pectin may be a significant effect in symptoms of heart and blood circulation..

Objectives: This study was undertaken to compare the effect of Foeniculi Fructus and Lonicerae Flos extract on the cerulein-induced acute pancreatitis in rats. Methods: Acute pancreatitis was induced by intraperitoneal injection of cerulein. Foeniculi Fructus extract (FE; 300㎎/㎏) and Lonicerae Flos extract (LE; 300㎎/㎏) were injected 2hr before induction of acute pancreatitis. Rats were sacrificed 6hr after first injection of cerulein. The severity of pancreatitis was assessed by measuring pancreatic weight/body weight ratio, neutrophil, lymphocyte, serum amylase activity, platelet activating factor (PAF) activity, tumor necrosis factor-a (TNF-a) activity, interleukin 6 (IL-6) activity and by histological assessments of inflammatory cell infiltration. Results: 1. The pancreatic weight/body weight ratios of FE and LE group compared with the control group were decreased significantly. 2. The neutrophil content ratio of FE and LE group compared with the control group were decreased. 3. The lymphocyte content ratio of FE and LE group compared with the control group were increased significantly. 4. The activities of serum amylase of FE and LE group compared with the control group were decreased significantly. 5. The activities of serum PAF of FE and LE group compared with the control group were decreased significantly. 6. The activities of TNF-a of FE and LE group compared with the control group were decreased significantly. 7. The activities of IL-6 of FE and LE group compared with the control group were decreased significantly. 8. The pancreas injected with FE and LE showed reduction of swelling of acinar cells, inflammation and vacuolization than the control group on light microscopic observation. Conclusions: These results suggest that Foeniculi Fructus and Lonicerae Flos extract have an effect to suppress inflammation on cerulein-induced acute pancreatitis in rats. But there are no significant differences between Foeniculi Fructus extract and Lonicerae Flos extract.
