After making tea by steaming the Artichoke(Hellanthus tuberosus) nine times and drying them nine times, the ingredients and functions of the Artichoke tea were compared to those of M. It had 342.27kcal/100g in its own deloped Artichoke tea, 73.87g/100g of carbohydrates, 6.80g/100g of crude ash and 8.21g/100g of crude protein. The total of free sugars were 32.66mg/100, among them, fructose 17.40, sucrose 9.03 and glucose 6.05 mg/100g. The total mineral contents of the developed tea was 2,785.67mg/100g. It was 2,563.93mg/100g of potassium, 97.52mg/100g of calcium and 88.78mg/100g of magnesium. The saturated fat of Artichoke tea was 30.34mg/100g and unsaturated fat was 69.66mg/100g, among which the linoleic acid was 47.0mg/100%, palmitic acid was 25.31mg/100% and linolenic acid was 8.61mg/100g. DPPH radical scavenging was 34.2% of teas that were developed, 5.2% of M's for comparison, and 44.0% of index materials. ABTS radical scavenging was 93.0% of teas developed, 61.9% of M's tea and 47.6% of index materials, and SOD like activity was 2.7% of teas developed and 1.6% of M's tea. The flavonoid content was 2.8 fold of the tea developed, 2.0 fold of M's tea and 1.7 fold of index material. The polyphenol content was 38.2 fold, 8.92 fold of M's tea and 14.0 fold of index material. The inhibition rate for ${\alpha}$-glucosidase was 9.83% teas developed and 8.92% of M's. The sensory evaluation compares to the one time extract and the five time extract. Based on the one-time extract, color of tea developed was 83.7%, the M's tea was 50.0%, the flavor was 78%, M's tea was 42.5%, the delicate taste was 66.7% of teas developed and M's tea was 37.5% and the overall acceptability was 73.3% of teas developed, M's tea was 47.5%. The comparison of M's tea showed that the extract decreased as we made it, and the overall symbol level decreased to 46.3% after five time-extyracts, while that of the developed tea decreased to 73.3%. The Artichoke tea developed this way is believed to have greater antioxidant function, higher effective substance content, and a higher affinity than M's tea an index material for comparison purposes.

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.
