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.

The behavior of silico-ferrite of calcium and aluminum (SFCA) phases and the influence of sintered ore quality were investigatedusing a confocal laser scanning microscope to understand how the Al2O3content of iron ore affects the sintered orestructure and the crystallization behavior of SFCA in a Fe2O3–CaO–Al2O3–SiO2 pseudo-quaternary system. The experimentalresults were used to inform simulations of the heterogeneous dynamic behavior in response to the rapid temperature changesand various chemical compositions typically encountered in actual sintering processes. Increasing the Al2O3content in theFe2O3–CaO–Al2O3–SiO2 pseudo-quaternary system led to the hematite content decreasing, which affects the reducibilityof the sintered ore. The correlation between the creation of SFCA and the cooling effect associated with varying the Al2O3is discussed in detail.

This is the fifth part of series of reports on the study on a blanced-type oscillating tillage implement using triple blades system. Previous reports were made on the characteristics of power requirement and vibration with which tillage implements were oscillated parappep and perpendicular to the travelling direction. In this paper, the locus and motion analysis of the tillage blade and factor analysis were carried out. Obtained results are as follows : 1. The loci od the blade edge were described as helix curve at vertical oscillation and as lacerated curve at horizontal oscillation to the soil bin movement. 2. The motion equations of blade edge are estimated as follows. Vertical forced vibration ?? ?? Horizontal forced vibration ?? ?? 3. The multiple regression equations for resultant oscillating acceleration draft, specific resistance, and torque were established by using frequency, amplitude, life angle of tillage blade, and velocity of carriage as indepentent vibrations, respectively. 4. By reducing the velocity ratio is increased providing higher effect of the reduced draft. But this effect contradicted to achieve the reduced osillating acceleration. Both effects should be considered simultaneously to find out the optimum operating condition. 5. The reduction effect of the oscillating acceleration was slightly favoured to the horizontal forced vibration type, but traction efficiency could be lowered due to the increased slippage. Therefore, it can be concluded that the vertical forced vibration type is more appropriate considering overall performances. 6. From the experimental results, the optimum operating conditions of the vertical forced vibration type are recommended as follow ; life angle 30 degree, operation velocity 0.15 metre per second, amplitude 4-6 millimetre, and frequency 22.5 hertz.

One of the most constant themes underlying the great historical struggles for social justice has been the demands for equality. The international guarantee of the principles of equality can not be exaggerated in evaluating of its importance. But various kinds of inequalities in the international societies are found such as the Indian Caste System, the South African Apartheid System, and discriminations on politic, economic, social, cultural, religion, race, etc. Nowadays there are discriminations in particular on account of sex in the fields of employment and occupation. This thesis put the stress on the sexual- equality under the international treaties, and emphasize the domestic application of sexual equality provisions under international law. The contents of this thesis may be summarized as followings ; Ⅰ. introduction Ⅱ. notion of the sexual equality and its grounded base. Ⅲ. sexual equality provisions under the international treaties. Ⅳ. fundamental principles of sexual equality in emploment and occupation. Ⅴ. domestic application of sexual equality under international treaties. Ⅵ. conclusion Equal Rights is called "grundnorm" in the constitutional values. The principles of equality is not created by the statute, but only confirmed in the legal rules. Moreover, sexual equality is more important concept in the, human rights, because women's growing economic importance and the demands for equal treatment and better employment opportunities have been influential in the development of public polices intended to improve their position in the labour market. There are some reasons why the provisions on sexual equality under international law could be effective in the domestic rules; Firstly, the principle of equality is "grundnorm" of the fundamental rights and so the sexual equatity could be valid throughout the world, not only in domestic laws but also in the international law. Secondly, our Constitution of the 5th Republic do ordain the domestic effectiveness of international law in Article5, saying "treaties duly concluded and promulgated in accordance with the constitution and the generally recognized rules of international law shall have the same effect as the domestic laws of the republic of Korea." And the Constitution declare the general principles of equality, or equality before the law, in Article 10 ;"......there shall be no discrimination in political, economic, civil or cultural life on account of sex, religion or social status." Lastly, the international guarantee of human rights is the global tendency in the modem democratic society. As the above mentioned, that the provisions on equality of the sexes under the "conventions and declarations" such as "Universal Declaration of Human Rights"(1948), "International Covenant of Human Rights"(1966), "ILO Convention no.l00"(1919), "European Economic Community Legislation"(1957), could be applicable,to the domestic legal rules. In accordance with the growing participation and changing roles of wemen in the labour market, moreover, we emphasize in particular on the problems of achieving equality of pay and employment, the influence of education and training, flexibility of working time and child-care arrangements for working parents, and the evolution of social security legislation to deal in a consistent way with men and women.

염화답실과 치환아닐린과의 친핵성 치환반응을 여러 용매계에서 진행시키고 이때의 반응속도 상수를 결정하였다. Br?nsted β값과 Hammett ρ?값들의 결과로부터 전이상태에서 결합파괴보다 결합형성이 우선함을 알 수 있었다. 분광용매화 상관관계식으로부터 용매의 수소결합주게(HBD) 산도 값(α)의 기여도 보다 용매의 편극-극성값(π?)의 기여도가 더 크게 작용함으로서 전이상태에서 결합 형성에 용매의 작용이 큼을 알았다. 또한 Dansyl과 Bansyl의 산 염화물보다 속도상수값이 크게 관측되어지는데 이것은 친핵체가 반응기질의 평면에 수직되게 공격함으로써 전이상태가 더욱 안정화되기 때문이며 이느 Marcus의 전이상태이론에서 concerted mechanism이 작용함을 의미한다 하겠다.
