Background: The initial history, physical examination, and ECG assessment should focus on identification of potentially serious noncardiac or cardiac disorders, including coronary artery disease, congestive heart failure, and electrical instability at the emergency room. additionally, it is essential to define disease severity, stability and need for emergency therapy. echocardiography is a useful tool for this purpose. especially Doppler echocardiography may be more sensitive and time-saving diagnostic tool for the evaluation of patients presenting with cardiogenic symptoms. So we evaluate the feasibility of the echocardiographic measurement by emergency physicain after short-term course. Method and Results: Twenty volunteers(10 male, 38.8±9.3 years) were included in the study for measurement of myocardial performance index and established parameters of ventricular function using conventional echo-Doppler methods. Myocardial performance index: (ICT+IRT)/ET, was obtained by subtracting ejection time(ET) from the interval between cessation and onset of the mitral inflow velocity to give the sum of isovolumic contraction time(ICT) and isovolumic relaxation time(IRT). The most of mean values of echocardiogrphic parameters were not significantly different between those of cardiologist and those of emergency physicians(p<0.01). The duration for measuring myocardial performance index was shortest among echocardiographic parameters. the validity of echocardiographic parameters measured by emergency physicians was proved relatively good. Conclusion: It is proved to be feasible for emergency physician to perform echocardiographic evaluation of ventricular function after short-term course

연구목적 : 이 연구에서는 K-MMSE에서 25점 이하를 받은 50대 이상 노인들을 MCI(Mild Cognitive Impairment) 군으로 보고 이들의 인지 기능 특성을 점화 효과를 중심으로 살펴보고자 하였다. 먼저, 점화 효과가 MCI 노인군에서 있어서도 유지되고 있는지를 알아보고, 인지 기능의 손상 정도에 따라 점화 효과가 유의미하게 변화하는 지를 살펴보고자 하였다. 방 법 : 본 연구에서는 K-NAME 점수 25점 이하의 노인 96명으 대상으로 ADAS-Cog와 일종의 간접 기억 검사 도구인 지각적 파악 과제를 제작하여 점화 효과를 측정하여 인지 기능의 퇴행이 시작된 고연령군이 나타내는 암묵 기억 능력 특성을 알아보았다. 점화효과는 컴퓨터 상에 사전 노출된 자극과 그렇지 않은 자극을 순간 노출시켜 미리 노출된 자극에 대해 반응 시간이 줄어들고 정확 반응이 증가하는 정도로써 측정하였다. 이 때 지능이나 연령, 학력 수준과 같은 변인이 미치는 영향을 통제하기 위해 한국판 웩슬러 지능 검사의 <어휘>, <토막> 소검사를 실시하였고, 인구통계학적 변인에 관한 면접을 실시하였다. 통계적 분석 과정에서는 먼저, 연구에서 측정된 점화효과의 특성을 알아보기 점화 효과 측정치의 기술 통계치를 구하였으며 다른 측정 변인들과의 상관 분석을 실시하였다. 마지막으로 측정된 점화효과가 인지 기능의 퇴행 수준에 비례하는 지의 여부를 파악하기 위해 ADAS-Cog 및 나이, 교육 연한 및 지능 수준을 독립변인으로 회귀분석을 실시하였다. 결 과 : 먼저 기술 통계 분석 결과에 의하면 본 연구에 참여한 피보험자들의 경우 점화효과에 의해 미리 노출된 자극을 평균 3.6개 더 정확히 파악하였으며 평균 59ms 더 빠르게 반응한 것으로 나타나 이들 집단에서도 점화효과가 유지되고 있음을 알 수 있었다. 다음으로 변인들 간의 상관 분석 결과에 따르면, 정확 파악 반응 점수에 따른 점화효과는 전반적인 인지 기능을 평가하는 K-MMSE 및 ADAS-Cog와 정적인 상관이 있는 것으로 나타났으며 반응 속도로 측정한 점화효과의 경우에는 나이와는 정적인 상관이, KWIS의 <어휘> 소검사 점수와는 부적인 상관이 있는 것으로 나타났다. 또한, 본 연구에서 사용된 점화 효과 측정치를 종속 변인으로 ADAS-Cog와 KWIS의 어휘 및 코막 소검사로 측정한 지능 수준, 나이와 교육 연한과 같은 인구 통계학적 변인을 독립 변인으로 회귀 분석을 실시한 결과에 따르면 정화간응 점수로 측정한 점화 효과의 경우 상관 분석 결과에서와 같이 ADAS-Cog 변인만이 유의미한 효과를 갖는 것으로 나타났으며 반응 속도로 측정한 점화 효과의 경우 나이의 효과만 유의미한 것으로 나타났다. 결 론 : 이러한 결과는 경미한 인지 기능의 손상이 진행되고 있는 고연령군의 경우에는 외현 기억 능력은 손상이 시작되지만 점화효과로 측정된 암묵 기억이 전반적으로는 유지되다가 인지 기능의 퇴행이 진행됨에 따라 노출된 자극을 더 정확히 파악하는 능력이 저하되고 점화 효과에 의해 인출 속도가 빨라지는 현상이 연령이 증가함에 따라 함께 증가하는 것으로 나타남을 말해 준다. Objectives : In this study, the cognitive characteristics, especially priming effect, of above 50 years old age group who had less than 25 points in K-MMSE were investigated. Methods : In this study, an implicit memory test measuring priming effect was made and administered ti old age people who had less than 25 points in k-MMSe in screening session. To control the effect of age, educational level and intelligence, demograohic variables were measured, and the subjects of KWIS, vocabulary and block design were administered. Descriptive statistical analysis of the two priming measures and correlational analysis between variables were done. To test the effect of cognitive functioning on priming effect multiple regression analysis was done. Results : Correlational analysis revealed priming score obtained from correct identification response was positively correlated with K-MMSE and ADAS-Cog. And priming score obtained from mean reaction time was positively correlated with age and negatively correlated with vocabulary substest of KWIS. The regression analysis results indicated from correct identification response, whereas age has significant effect on priming score obtained from mean reaction time. Conclusions : The results revealed that as cognitive deterioration progresses priming effect which identify primed stimulus correctly diminish, and as one grow older within age 50 to 70, priming effect which identifies primed stimulus quickly increase.

This study was conducted to develop a processing method for dry-curing beef ham with Korean traditional sauces and to investigate the quality properties of the dry-cured beef hams. Semitendinosus muscle from Hanwoo was spread with sundried salt (C), sun-dried salt mixed with red pepper paste (T1), and sun-dried salt mixed with soybean paste (T2), and inserted into washed Hanwoo large intestine. It was then dried and fermented for 75 d. Moisture contents of the hams were 46-48%, without any significant differences. T1 showed the lowest pH among the three dry-cured hams, while water holding capacity (WHC) of T2 was found the lowest (p<0.05). In mechanical color determination, C showed higher CIE $a^*$ and CIE $b^*$ than T1 and T2 (p<0.05), however CIE $L^*$ did not show any significant difference. In texture, T1 demonstrated significantly lower springiness than C (p<0.05). The sensory properties of all dry-cured hams did not show any significant difference, but T1 indicated a higher taste, saltiness and overall acceptability than others, whereas C gathered the highest score in color and flavor. In conclusion, the dry-curing by combination of sun-dried salt mixed with red pepper sauce (T1) showed higher quality properties of the Hanwoo dry-cured ham. 우리나라 전통장류를 건염햄 제조에 접목한 건염햄의 제품을 개발하기 위해 염지과정에서 첨가한 고추장과 된장이 건염햄 품질에 미치는 영향을 조사하고자 실시하였다. 천일염(C), 천일염+고추장(T1), 천일염+된장(T2)을 한우의 반힘줄모양근(m.emitendinosus)의 표면에 골고루 발라주고 세척한 한우 대장에 충진한 후 75일 동안 건조 및 발효시켰다. 한우 반힘줄모양근 건염햄 품질을 조사한 결과, 건염햄 수분함량은 46.45-48.04% 수준으로 유의적인 차이는 없었다. T1은 모든 처리구 중에서 pH가 가장 낮았고 T2는 WHC가 가장 낮았다(p<0.05). 기계적 육색 측정에서 C가 $a^*$와 $b^*$가 전통장류 처리(T1, T2)보다 높았으나(p<0.05), $L^*$은 유의적인 차이가 없었다. 조직감에서 T1은 C보다 탄력성이 유의적으로 낮았다(p<0.05). 관능평가 결과 모든 처리구에서 유의적인 차이가 없었고 C는 제품색과 향미가 높은 점수를 받은데 반해, T1은 높은 맛, 짠맛, 그리고 전체적 기호도가 다른 처리구에 비해 높았다.

Extract of Centella asiatica(ECA), which is poorly water-soluble extract from the Centella asiatica is known to express excellent wound healing properties. ECA-β-cyclodextrin (asiaticoside-β-cyclodextrin and genin-β-cyclodextrin) solid dispersion system, which was prepared by freeze-drying method, was formulated as gels containing poloxamer 407 and propylene glycol, and evaluated with respect to their viscosity. stability, skin permeation and drug amount in the skin of hairless mouse. The average molar ratio asiaticoside-β-CD and genin-β-CD was 1:1,7 and 1:22, respectively. When the molar ratio of genin and β-CD was 1:5, madecassic acid made 100% solid dispersion system and asiatic and about 65%. In dissolution study, >99% of asiaticoside from asiaticoside-β-CD was dissolved in 5 minutes, and >99% madecassic acid and >64% asiatic acid from genin-β-CD. The apparent viscosity of poloxamer 407 gels with ECA-β-CD solid dispersion system increased in proportion to poloxamer 407 and gels showed that asiaticoside was most stable and madecassic acid stable and asiatic acid similar to stability of gel with free ECA. The permeation amount of asiaticoside in poloxamer gels through-hairless mouse skin decreased as the concentration of poloxamer 407 increased. When propylene glycol was added at the level of 10%, the permeation amount of asiaticoside at poloxamer gels through hairless mouse skin increased but from 15% it decreased. The permeation of asiaticoside into the skin of hairless mouse was estimated to be about 0.10 ㎍/㎠.

It is now feasible to achieve high performance in numerical computations with parallel processing technology. In order to use parallel computers in a specific application, algorithms need to be developed and mapped onto a parallel computer architecture[1,2,5]. In this paper, we introduce the s-step block Lanczos method for finding a few multiple eigenvalues of symmetric large sparse matrices in a similar way to the s-step Lanczos method[4]. One iteration of the s-step block Lanczos algorithm corresponds to s iterations of the standard block Lanczos algorithm. The reduction matrices generated by s-step method are similar to reduction matrices generated by the standard method. The s-step method ahs improved data locality, minimized global communication and ahs superior parallel properties to the standard method.
