DPPH 라디컬 소거력은 개발한 차 34.2%, 비교용 M사차 5.2%, 지표물질 44.0%였다. ABTS 라디컬 소거력은 개발한 차 93.0%, M사차 61.9%, 지표물질 47.6%였다. SOD 유사활성은 개발한 차 2.7%, M사차 1.6%였다. 플라보노이드 함량은 개발한 차 2.8 fold, M사차 2.0 fold, 지표물질 1.7 fold 였다. 폴리페놀 함량은 개발한 차 38.2 fold, M사차 8.92 fold, 지표물질 14.0 fold였다. ${\alpha}$-Glucosidase 저해율은 개발한 차 9.83%, M사차 8.92%였다. 기호도는 1회 우린 것과 5회 우린 것을 비교하였다. 1회 우린 것을 기준으로 할 때 5회 우린 것의 기호도 중 색은 개발한 차 83.7%, 비교용 차 50.0%, 향기는 개발한 차 78.0%, 비교용 차 42.5%, 맛은 개발한 차 66.7%, 비교용 차 37.5%, 종합적인 기호도는 개발한 차 73.3%, 비교용 차 47.5%로 나타났다. 이같이 비교용 M사차는 우릴수록 추출 성분이 감소하여 5회 후에 종합적인 기호도는 46.3%로 감소한 반면 개발한 차는 감소폭이 적어서 73.3%를 나타냈다. 이같이 개발한 돼지감자차는 비교용 M사차 및 지표물질보다 항산화 작용이 강하고 유효 물질 함량도 더 많고, 기호성도 높으므로 질병 예방 및 개선 효과가 클 것으로 생각한다.

This is a research on general evaluation of the nursing profession which is a professional job, a suitable calling to women and is developing academically day by day. The author gave some questions to the patients, doctors, people, student nurses-themselves and got the following results; (A) General concept about nursing profession A nurse is a member, of a medical team who works for people′s health promotion(50.8%). The reason that the nursing profession is a good one is that it is a rewarding job to care for sick patients(78.9%). The spirit is the most important factor for the nurse(84.8%) and the nursing profession is a suitable calling to women (76%). The description of nurses as "The angels in white dress" is an appropriate one (44.6%) or only a beautiful expression(47.4%) (B) Nurses as actually seen by doctors and patients. They work only obligatorily (47.8%)-Doctors They try to relieve, the patient′s physical discomforts in all sincerity (65.6%), also they to decrease the patient′s mental apprehension (56.7%). (C) Satisfaction in the nursing profession. Nurses satisfaction in the nursing profession is general(68.8%) and student nurses satisfaction in selecting nursing is fulfilled (50.9%). One reason for dissatisfaction among nurses and student nurses is people's failure to understanding the nursing profession(40.1%), One reason for satisfaction is that it is a rewarding job caring for sick patients(35%). (D) Is the nursing professional job? People think the nursing profession is a professional job like doctors or lawyers (60.2%). (E) Are they academic? People think the nurses are academic(37.8%) but nurses read only interesting items in the "Journal of Korean Nurse"(67.7%). (F) Opinions about nurses′going out of the country. Doctors and nurses agree that after 1-2 years′experience in this country(78.5%) and student nurses want to go out where there is on opportunity(73.1%). Student's purpose of going out is to enrich their stock of information(71.3%), doctors think, it is for training in nursing knowledge and skills (47.8%). (G) Opinions about nurse′s social affairs. They want nurses to be controlled(44.4%) and also think that the nurse's demonstration in the National Conte. was reasonable (36.3%). (H) Would you make your daughter a nurse? They favour their daughter′s becoming a nurse(17.4%) because they think it is a rewarding job to care for sick patients(42.5%).

Pulmonary and/or bronchial aneurysm with systemic thrombophlebitis can be seen in the case of both Behcet's disease and Hughes-Stovin syndrome. These two diseases may be indistinguishable since the clinical, radiological, and histopathological findings are similar in both cases. In particular, from the perspective of pulmonary involvement, hemoptysis is the leading cause of death in both conditions and is followed by aneurysmal rupture. Here, we report a case in which surgical resection was performed for a patient presenting recurrent hemoptysis as an atypical presentation of Behcet's disease.

Ti 및 S를 함유하는 강종의 연속주조시 노즐막힘 현상이 자주 발생한다. 이러한 강종의 연주기술과 생산성을 향상 시키기 위해서는 노즐막힘 발생을 방지하기 위한 새로운 기술의 개발이 필요하다. 노즐막힘은 노즐내벽에 개재물의 부착으로 인해 발생되는 것으로 용강의 물성 혹은 내화물 재질의 개선을 통하여 방지하거나 저감할 수 있다. 본 연구에서는 노즐내 용강에 Mg 증기를 취입하였을 때의 내화물과 용강 계면에서의 반응 및 현상에 대하여 조사하고 내화물/용강계면에서의 생성물 분석과 용강중 S와 Ti의 농도에 따른 노즐 내화물과의 접촉각을 측정하였다. Mg증기는 MgO-Al 혼합물을 가열함으로 Al에 의한 Mg 의 환원반응에 의해 발생되며, 온도와 MgO와 Al 분말의 입도에 따른 Mg증기 발생거동에 대하여 고찰한다.

A new course keeping controller for RIB(Rigid Inflatable Boat)-type USV(Unmanned Surface Vehicle) is developed using pilot's steering pattern. A pilot's simple steering pattern is found out from various course change tests. It is used to course keeping algorithm, suitable for large course change more than 60 degrees. To validate the course keeping controller, sea trial tests are conducted. From sea trial test, new course keeping controller shows good performance with less overshoot, maximum roll angle less than $20^{\circ}$, which makes it possible that fast course changes without slip motion of USV.

In this study, R/S analysis which was proposed by Mandelbrot & Wallis (1969) was applied to evaluate the presence of the fractal property in the cone tip resistance of in-situ CPT data. Hurst exponents (H) were evaluated in the range of 0.660$\sim$0.990 and the average was 0.875. It was confirmed that a cone tip resistance data had the characteristic of fractals and it was expected that cone tip resistance data sets are well approximated by a fBm process with an Hurst exponent near 0.875. It was also observed that the boundary between layers were obviously identified as a result of R/S analysis and it will be usage in practices.

A 21-year-old male visited our emergency room. He could not remember the mechanism of injury. He was found beside a motorcycle. Initial vital sign was stable. Observation and conservative treatment were planned at the intensive care unit (ICU). On the third day at ICU, he complained sudden flank pain. It was colicky and hard to control. Without the pain, he had no specific symptom, sign, or laboratory findings. On computed tomography, renal pelvis was filled with hematoma which induced hydronephrosis. Double-J catheter and percutaneous nephrostomy was implemented by an intervention radiologist. Hematome in the renal pelvis was aspirated during the procedure. Symptom of the patient was subsided after the procedure. He was discharged without specific complications.

In the present article, we investigate the possibility of a real-valued map on the space of tuples of commuting trace-class self-adjoint operators, which behaves like the usual trace map on the space of trace-class linear operators. It turns out that such maps are related with continuous group homomorphisms from the Milnor's K-group of the real numbers into the additive group of real numbers. Using this connection, it is shown that any such trace map must be trivial, but it is proposed that the target group of a nontrivial trace should be a linearized version of Milnor's K-theory as with the case of universal determinant for commuting tuples of matrices rather than just the field of constants.

For a bounded linear operator T on a separable complex infinite dimensional Hilbert space $\mathcal{H}$, we say that T is a quasi-class (A, k) operator if $T^{*k}|T^2|T^k\;{\geq}\;T^{*k}|T|^2T^k$. In this paper we prove that if T is a quasi-class (A, k) operator and f is an analytic function on an open neighborhood of the spectrum of T, then f(T) satisfies Weyl's theorem. Also, we consider the tensor product for quasi-class (A, k) operators.
