The author analized 17 complete denture patients with lateral cephalometric roentgenograms and following results were obtained: 1. The angle between the Ala tragus line and the occlusal plane was $4.38^{\circ}$. 2. The angle between the Ala tragus line and the Frankfort horizontal plane was $13.68^{\circ}$. 3. The line between the mouth corner and the retromolar pad was more parallel to the occlusal plane than the Ala tragus line.

미국 병원들의 진료영역 확대는 많은 잠재적인 위험을 내포하고 있다. 미국병원협회 (AHA)의 진료의 질과 의료형태에 관한 연구분과에 따르면 가정간호, 정신질환간호, HMO치료 등이 병원에 있어서 앞으로의 위험 책임 영역이 된다. 이러한 3가지 특별분야 외에 2 가지의 일반영역이 있는데 그것은 환자와의 관계, 기술의 문제 등이다. 따라서 Hospitals지 에 나타난 새로운 위험책임분야를 살펴보기로 한다. 이 기사는 병원회보 제46호부터 제 50호까지 실린 것으로서 독자들의 요청에 의해 협회지에 게재키로 했다.

이 연구에서는 복부비만을 가진 고령여성을 대상으로 대사증후군 동반 유무에 따른 대사증후군 위험요인과 hs-CRP와의 관련성에 대해 알아보고자 하였다. 대사증후군 진단은 AHA/NHLBI (American Heart Association/National Heart, Lung and Blood Institute) 2005년 기준에 따라 5가지 기준 중 3개 이상 해당되는 경우 대사증후군 진단군(MetS, N=77), 2개이하의 위험요인에 해당하는 경우 대조군(Absent, N=97)으로 분류하였다. hs-CRP 농도는 대사증후군 위험요인과 밀접한 관련이 있으며, 특히 복부비만(r=0.190, p=0.014), 공복혈당(r=0.240, p=0.002), HDL-콜레스테롤(r=-0.164, p=0.035)과 연관이 있음을 확인할 수 있었다. 또한 대조군보다 대사증후군 진단군에서 hs-CRP가 높게 나타났으며(p=0.007), 복부비만 상태일지라도 높은 혈당(p=0.006)과 낮은 HDL-콜레스테롤혈증(p=0.010)의 위험요인이 있는군에서 hs-CRP가 높았다. 결론적으로 복부비만이 있더라도 대사증후군 위험요인의 동반 유무에 따라 염증관련 위험도가 달라짐을 알 수 있었다.

Objective: Dyslipidemia is recognized as a prominent risk factor for cardiovascular and cerebrovascular diseases but it is manageable through therapeutic and lifestyle intervention. Interpreting the latest guidelines is essential for an application of recommendation from guidelines into clinical practice. Therefore, this study aimed to compare the most recent guidelines on dyslipidemia treatment recommendations in Korea and USA. Methods: This study analyzed and compared 2015 Korean guidelines for the management of dyslipidemia, 2013 American College of Cardiology/American Heart Association (ACC/AHA) guideline and 2016 supportive guidelines from ACC. Results: A comparison was made focused on the following: target patients based on cardiovascular risk assessment, target goal, and treatment strategies including statin and non-statin therapies. Four target patient groups by risk were suggested in 2015 Korean guideline and cardiovascular risk factors were also considered for initiation of lipid lowering therapy. Titrated statin regimen was recommended by Korean guideline to reach LDL cholesterol and non-HDL cholesterol target level. In 2013 ACC/AHA guideline, four statin benefit group was introduced considering ASCVD risk and high intensity statin or intermediate intensity statin use were recommended without dose titration. 2016 update was to support non-statin therapy based on updated evidence and new consideration of ezetimibe, PCSK9-inhibitor and bile acid sequestrant was brought up. Conclusion: Guidelines are continuously updating as new and important clinical data are constantly released along with the advent of newly approved drugs for lipid disorder. This article provides resources that facilitates uptake of these recommendations into clinical practice.

The extraction of three kinds of amido podands, N,N,N'N'-tetrabutyl-3-oxa-pentanedi- amide (TBDGA), N,N,N'N'-tetra-isobutyl-3-oxa-pentanediamide(TiBDGA) and N,N,N'N'-tetra- butyl-3,6-dioxa-oct-anediam- ide(TBDOODA) on U(VI),Pu(IV), Am(III), Eu(III) and other metal ions is studied in nitric acid solutions. 40%octanol-kerosene is chosen as diluents to eliminate third phase and emulsion. TBDGA and TiBDGA show extraction selectivity to An(III) and Ln(III) much higher than to U(VI) and Pu(IV). Fe, Ru and Mo is poorly extracted by the three kinds of amid podands in 2~3mol/L $HNO_3$ solutions. Aiming to eliminate interface crude when using simulated HLLW solution in the system of 0.2mol/L TBDGA/Octanol＋kerosene, acetohydroxyamic acid was adapted. Distribution ratio of zirconium was decreased when adding acetohydroxyamic acid in aqueous solution, and interface crude disappeared as mixing extractant with HLLW. The counter-current extraction test is carried out in a set of miniature mixer-settler, with 0.2mol/L TBDGA/ 40% octanol-kerosene as extractant to separate U(VI), Pu(IV), Am(III) and Eu(III) from simulated high level liquid waste(HLLW) solution. In battery A, lanthanides and actinides are coextracted into organic phase with the recovery of 99.98% for U(Ⅵ), >99.99% for Pu(IV), and >99.99% for Am(III) and Eu(III) respectively. In battery R1, 99.99% U, 86.2% Pu and a part of Am or Eu are stripped into aqueous phase by 0.2mol/L acetohydroxyamic acid (AHA) in 0.01mol/L $HNO_3$ solution. In battery $R_2$, Am, Eu and remained Pu are completely back-extracted by 0.2mol/L AHA. This separation process contains no salt reagent, and it is not necessary to dilute HLLW feed.

The purpose of this study is to investigate the pattern of metabolic syndrome(Mets) in stroke patients who were hospitalized in Daejeon oriental hospital. The present study was done over 445 hospitalized patient with stroke in the Daejeon University Oriental Medical Hospital in the period of November 2006 to December 2008. Stroke patients had been interviewed by residents and specialists who studied standard operation procedures in Fundamental study for Standardization and Objectification of Differentiation and Pattern Identification of Syndrome of Oriental Medicine for Stroke. We analyzed all registered data and evaluated the prevalence of Mets and specific components of Mets. The distribution of Mets in stroke patients according to American Heart Association/National Heart Lung and Blood Institute(AHA/NHLBI) criteria is 65.63%. The distribution of Mets in stroke patients according to International Diabetes Federation(IDF) criteria is 48.05%. The distribution of female patients is higher than that of male patients. The distribution of central obesity, low HDL cholesterol and hypertension is higher in female patients. There is no significant relationship between Mets and stroke type in AHA/NHLBI criteria.. But, there is significant relationship between Mets and stroke type in IDF criteria.

The purpose of this research was to evaluate retention of cognitive knowledge, psychomotor skills and self-confidence on CPR 3 months after CPR training program. The sample consisted of 39 nursing students. We provided one rescuer CPR training program for nursing college students on the basis of AHA. The questionnaires for knowledge of CPR were developed 50 items based on AHA guidelines. Self-confidence were checked by 11 items questionnaires. The accuracy of CPR skills were checked by Skillreporter CPR training manikin and by researcher's evaluation based on CPR skill checklist. The results were as follows ; 1. The majority of participants didn't have any previously experiences of CPR training (76.9%). Only 15.1% previously took the CPR training with CPR practice. 2. In terms of self-confidence of CPR. The score were increased for 2 days (p>.001) but retention of self confidence was significantly statistical decreased in 3 months after training (p<.001). 3. There was a statistically significant decrement in mean of knowledge of CPR between 2 days and 3 months after CPR training (p<.001). 4. There was a statistically significant decrement in cognitive knowledge of CPR based on CPR skills checklist(p<.001). 5. Retention scores of psychomotor skills of CPR 3 months after training were 42.10% in numbers of adequate ventilation, 52.81% in numbers of adequate chest compression (p<.001) respectively. 6. Retention of passing rate on chest compressions of CPR 3 months after training was 27% (p<.001), on ventilation was 2.63% (p>.001). The error items with statistically significant differences 3 months after CPR training were too little ventilation (74.36%) and too little chest compressions (92.31%). The results of the study suggest that we need further evaluation of course components which could improve retention of CPR for all trainees.

본 연구에서는 수계 레독스 흐름전지에서 사용하는 멤브레인 특성분석방법을 개선하여 비수계 레독스 흐름 전지를 위한 멤브레인 특성분석방법을 확립하였다. 비수계 레독스 흐름 전지에 적합한 멤브레인 특성을 확인하기 위해 상용 멤브레인의 이온교환능력, 이동수, 이온 전도도, 활물질 투과도, 전지효율 실험 등 특성분석들을 수행하였다. 상용 음이온 교환 멤브레인의 특성분석 실험을 통해 충 방전 효율 및 에너지효율과 이온 선택성의 상관관계를 조사하였다. Neosepta AHA 음이온 교환 멤브레인은 이동수 측정에서 0.81의 값으로 비수계 전해질에서 비교적 낮은 이온 선택성을 보였지만, 충방전 전지효율 평가에서는 92%의 충 방전효율과 86%의 에너지효율을 각각 나타내었다. 또한 이온의 선택성이 없는 다공성 멤브레인은 높은 전류밀도의 비수계 레독스 흐름 전지에 적절함을 알 수 있었다.

본 논문에서는 회로 설계 소프트웨어에서 사용되는 primal-dual 최적화 문제의 해를 구하기 위해 필요한 삼중 행렬 곱셈 연산 ($P=AHA^{t}$)의 성능 개선에 관하여 연구하였다. 이를 위하여 삼중 행렬 곱셈 연산의 속도를 개선하기 위하여 기존의 2단계 연산 방법을 대신하여 1단계 연산 방법을 제안하고 성능을 분석하였다. 제안된 방법은 희소 행렬 H의 블록 대각 구조의 특성을 이용하여 부동 소숫점 연산량을 감소시킴으로써 성능 개선을 이루었으며 더불어 메모리 사용량도 기존 방법에 비하여 50% 이하로 감소하였다. 그 결과 Intel Itanium II 플랫폼에서 기존 2단계 연산 방법과 비교하여 속도 면에서 주어진 실험 데이터 집합에 대하여 평균 2.04 의 speedup을 얻었다. 또한 본 논문에서는 플랫폼의 메모리 지연량과 예측된 캐쉬 미스율을 이용한 성능 모델링을 통하여 이와 같은 성능 개선 수치의 가능 범위를 보이고 실측된 성능개선을 평가하였다. 이와 같은 연구는 희소 행렬의 성능 개선 연구를 기본 연산이 아닌 복합 연산에 적용하는 연구로써 큰 의미가 있다.
