Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

이차 우식은 수복 실패의 주된 원인 중 하나로 지목되고 있으며, 이로 인해 빈번히 재수복을 하게 된다. 이차 우식은 항우식 작용이 있는 불소를 함유한 수복물을 사용하여 예방될 수 있다. 구강내에서 불소를 유리하는 것으로 알려진 글라스 아이오노머 수복재는 불소를 장기간 유리할 뿐 아니라 불소의 재충전 및 재유리 능력이 있어 불소의 저장소 역할을 할 수 있다. 따라서 본 연구는 통상의 글라스 아이오노머와 고점도 글라스 아이오노머 및 복합 레진을 대상으로 불소의 유리 양상과 불소도포를 통한 재흡수 후 유리 양상을 알아봄으로써 기존의 수복재와 새로운 수복재간의 임상적 유용성을 평가할 목적으로 시행하였다. 4종의 수복재를 대상으로 불소 유리량 및 2% NaF로 재충전 후 불소 유리량을 각각 측정하여 다음과 같은 결과를 얻었다. 1. 실험 대상의 모든 글라스 아이오노머 수복재는 초기에 다량의 불소를 유리하고 이후 점차 감소하는 경향을 보였다. 2. 2% NaF 용액을 통한 재충전 후의 유리량은 Fuji IX, Ketac Fil, Ketac Molar, Z-100의 순으로 나타났다. 3. Fuji IX을 제외한 모든 실험 대상의 수복재에서 수분의 영향으로 표면 경도는 유의하게 감소하였고 불소 재충전 후 유리량은 수분 흡수와 비례하였다(P<0.05). 4. Fuji IX이 초기 유리량에 비해 재충전 후 더 많은 불소를 유리였다(P<0.05). The replacement of dental restorations due to secondary caries is a continuing problem in restorative dentistry. The secondary caries can be partly prevented by using fluoride containing dental materials such as glass ionomer cement, which releases and be recharged with fluoride ion acting as a fluoride reservoir. For the purpose of investigating the behaviors of fluoride release and recharge of conventional and high viscosity glass ionomer cements, the experiment was performed on the seven specimens each from 4 kinds of materials; 1 kind of conventional glass ionomer cement, 2 kinds of high viscosity glass ionomer cements and 1 kind of composite resin. The amount of fluoride release was measured over 7 days with pH/ion meter and fluoride specific electrode. After measuring daily fluoride release, the specimens were recharged with 2% NaF solutions for 4 minutes and measured for 3 days with recharging repeated two consecutive times. The results were as follows : 1. Significantly more fluoride was released at first day after recharge in all materials except Z-100. 2. High viscosity glass ionomer cements released more or nearly equal amount of fluoride after recharge compared with the initial release(P<0.05). 3. The fluoride release after recharge with 2% NaF solution was in order of Fuji IX, Ketac Fil, Ketac Molar, Z-100.

이 논문은 MOSFET로 구성된 등가 Half-bridge형 고주파공진형 인버어터에 대해 기술하고 있다. 시분할 방식에 의한 게이트회로를 구성하여 구동함으로써 출력단에는 두개의 인버어터에서 동작되는 순시위상이 합성되어 있어 나타나므로 부하단 출력주파수는 소자의 수위칭주파수에 대해 두배가 되고 수위칭 손실이 경감되어 소자의 평균전류가 증가한다. This paper proposes a high frequency resonant inverter consisting of equivalent half bridge model using MOSFET. In this paper time-sharing control method is applied. as a result the output frequency is two times as high as switching frequency of device and average current of device is increased because of decreasing switching loss.

Invasive pulmonary aspergillosis is known to have a poor prognosis and major cause of morbidity and motality in patients with hematologic disease. Without adequate therapy, invasive pulmonary aspergillosis will almost always progress to fatal pneumonia. Early administration of antifungal agents in patient with invasive pulmonary aspergillosis is most important. And surgical resection of aspergillous-infected tissue may be useful in patients with lesions that are contiguous with great vessel and lesions causing hemoptysis. We reported a rare case of surgical resection as curative treatment for invasive pulmonary aspergillosis patient in 58-year-old man who had the history of acute myeloid leukemia.

The purpose of this study was to evaluate body dissatisfaction, eating attitudes, and exercise behavior in female adolescents and to develop strategic countermeasures against those epidemic phenomenon. A total of 269 junior female high school students participated in this study, and were divided into three groups based on the body mass index (BMI); BMI<18.5: underweight (UW), 18.5-24.9: average weight (AW), and 25.0-29.9 overweight (OW), A questionnaire consisted of Body Dissatisfaction Index (BD[), Eating Attitude Test-26 (EAT26), Obesity Related Stress (ORS), and exercise behavior was administered, For the comparisons of means, one-way ANOVA was employed, and relationships between variables were assessed by correlation coefficient, For the analyses of relationship between BDI and EAT26, and physical activities, X² was utilized, The BD[ between UW and OW was significantly different (P<.05) while no differences were found in EAT26 among groups. ANOVA revealed ORS score was statistically different (P<.05), but post-hoc test did riot show any differences among groups, In each group, BMI and EAT26, and BMI and BDI were highly correlated (P<.05). However no relationships were found between BDI and EAT26. When comparing the level of physical activities among groups, no differences were found. The prevalence or inactive (less then average) was 24.7, 28.9, and 45.2% in UW, AW, and OW, respectively. The desire for exercise was 94.6, 94.5, and 100% in UW, AW, arid OW, respectively, and this was statistically different (P<.05), The perception or exercise necessity was highly rated in all groups, particularly in OW female adolescents.

In this paper, the behavior of single and pile groups under lateral load are studied through laboratory experiment. Model piles were made of brass pipe with outer diameters of 28.6mm, which are laid in loose, medium, dense sand of zigzag arrangement. The test results are as follows. As the increasing of relative density, the maximum bending moment is increased. The point of maximum bending moment on single pile measured at 5∼8B(diameter of pile) depth from surface, and group piles measured at 5∼l1B. The bending moment obtained by this experiment similiar with the one obtained by the Chang's theory.

This paper presents a design method of fuzzy logic controller(FLC). In the proposed method, the parameters of FLC are determined by using Genetic Algorithms(GAs), which is an optimizing algorithm. Two types of FLC are considered. One is FLC with control rules whose fuzzy variables are all assigned by linguistic quantity. The other is FLC with control rules which are inferenced with simplified reasoning. For each FLC, the method of applying the GAs to determine the parameters of the FLC is proposed. By the simulation study for four systems with different characteristic, the usefulness of the proposed design scheme is discussed.
