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.

This study was aimed to get the course which is caused by Neuropsychiatric symptoms in Sang-Han. Therefore this study is based on 『Euhak-Ipmun. Sang-Han』(『醫學入門.傷寒』) classfied mainly by symptoms. The results were summerized as follows: 1. Neuropsychiatric symptoms in 『Euhak-Ipmun. Sang-Han』(『醫學入門. 傷寒』) are explained as Pal-Gang(八綱), which shows those are settled down to a systematic oriental medical theory. 2. Pal-Bup (八法) used in the cure of symptomatische psychose in 『Euhak-Ipmun. Sang-Han』(『醫學入門. 傷寒』), which is intended to boost the effect of cure, choosing the respondent cure method about various causes. 3. Pal-Gang(八綱) and Pal-Bup(八法) in『Euhak-Ipmun. Sang-Han』(『醫學入門·傷寒』) are improved by Lee-Chun(李 ) who added Jang-gi(張機)'s Sang Han theory and new medical thought in the ages of Geum. Won. 4. Lee-Chun(李 ) believed that Neuropsychiatric symptoms which appeared in Sang Hang is caused by the "Unbalance(不平)". So he wanted to reach harmony of "Jeong(精), QI(氣), Shin(神), Hyul(血)" after improving the status of "Unbalance(『不平』)" toward the status of "Balance(平)".

『Gunbaba』, written by Kim Hye-sung, a rising writer of North Korea, is a historical long-novel which is remarkably highlighting the characteristic of the independence and nationality of our people by standing a Josun military officer as a hero with a historical background of Josun which was dotted with a long spell of national ordeal such like the residence of the Japanese supervising Agent in 1906, the dismission of the Korean army in 1907, the Special Envoys of Hague, and the deposition of King Gojong. 『Gunbaba』 has a framwork of latitude of longitude of supporting characters such like Jock-song, Kwon Ki-hong, Kim Hui-sook, Yang Seol-hee, and Lee around a hero, Nam Sang-duk, a main character. This work is, so to speak, based on ' the First People of Josun', the ideology of 'nationalism', which was stressed by Kim Jeong-il, the chairman of the defence committee after he came to the force. This ideology was functioned as the driving force that caused the writing tendency such like the realistic works of the historical theme that were in great vogue in the North Korean society. Especially in one point, this work gives fun to the readers that it focuses on the nationalism by describing the various types in the decadent stage to the Japanese colonialism of the various kinds of characters, who had collaborated with the Japanese Imperialists in many ways, such as Kim Tae-jin, Lee Wan-yong, and Park Young-hyo of the day it shows. First of all, Nam Sang-duk, the hero, is actually described as a person with many troubles in the work. Nam Sang-duk, who graduated first from the Senior Military Academy and got appointed to a platoon commander of the Josun army, was continually playing a role as a trouble-maker. Without regard to his soldiership, he is engaged into some trouble between 'Cheongcheon Pub' which is operated by Kwon Soon-sil, his friend Kwon Ki-hong's elder sister and 'Sakura Coffee Shop' which is operated by a Japanese, Yoshiko and he is behind bars and then is released. In fact, it seems that the writer has intention in his mind that Nam Sang-duk, his hero, kept his foot in the trouble to make him <a sensible person>. Besides, the hero, Nam Sang-duk, deeply impressed by the Drive for National Debt Compensation of Yang Ki-tak, organized the Danyeonhoe in his Josun army and raised money to participate in the Drive for National Debt Compensation. Moreover, going on his way, he found a boy dying hit by the new train which first showed in Seoul and hurry to the doctor's office carrying him on his back and gave some portion of the fund for the Drive. After all, these activities of him seem to include the writer's purpose not only to show the patriotism of Nam Sang-duk but also to reveal the falseness and the oppression of the Japanese Militarism through the victim by the train, which is propagandized as the symbol of modernization and the point of the modem civilization which is propagandized by the Japanese Imperialism. Another one, Park Sung-hwan, the battalion commander, heard the news of the painful outcries of Yang Sung-hwan who had known the reality of the dismission of Josun army ordered by the Emperor' false will being forced by Lideungbakmun and his pro-Japanese Lee Wan-young, killed himself by a pistol. Nam Sang-duk, the hero, hearing the gun-sound and witnessing the scene of the suicide, dashed to the common soldiers, stimulated them, and resisted in arms. Nam Sang-duk, determined to die and with a bundle of explosive, rushed to the city gate where the Japanese machine-gun position and the fortress were lined up with and died a heroic death raising the morale of the rebel forces. These gallantry and intrepidity come to the victory in the end and they transfer to the esthetical category of 'heroism' and 'nobility' which the North Korean esthetics categorized. In 『Gunbaba』, there appears a peculiar assistant, Park jwa-su, who is set up a very

Ferromagnetic material like the steel tubes can easily distort eddy current testing signal due to increased magnetic permeability for defects. Because magnetic field of the test probe is affected in an inconsistent way when the material under the testing has permeability. This permeability effect can be reduced by magnetic saturation. In this paper eddy current testing system was developed to detect flaws on the steel tubes. Magnetic saturation probe with helmholtz coil was designed for saturation and inspection of the steel tubes. When using the designed test probe, the relationship between flaw signals and noises was obviously discriminated. Additionally, a high pass filter was included in the eddy current board to minimize noises due to DC magnetic field.

Kinetic studies of nuclsophilic substitution reaction of dabsyl chloride with pyridines have been investigated at 30℃ in a range of methanol-acetonitrile bianary solvent mixtures. The order of magnitude fo reactivity is β-picoline > pyridine > 1.5-N D A > α-picoline to react with dabsyl chloride, especially in case of α-picoline, the reactivity revealed lower than others, it is suggestd that nitrogen atom of pyfidine ring has a steric hinderance by the neightboring methyl group. The value of ρ(-0.96∼4.59) and β(0.36∼0.67) associated with a change of substituent in the nucleophile are large and indicate a realtively advanced bond formation in the transition state. Solvatochraomic correlations were predicted the importance of bond formation transition state, showing a greater contribution of polaritypolarizability (π*) lone paired to hydro-gen bond donar acidity (α). We conclude that the reaction of dabsyl chloride with pyridine proceed via S2 type reaction mechanism, as well as the reaction of dansyl chloride pyridine.

The effect of ozone on the formation and the removal of disinfection byproducts(DBPs) of chlorination process was studied to elucidate the performance of water treatment process. The samples of raw water, prechlorination process, and preozonation process were analyzed quantitatively according to the Standard Methods for the Examination of drinking water. As a result, most of total trihalomethanes(THMs) which were formed in prechlorine treatment process was not removed in the preozonation process. Most of haloacetic acids(HAAs), haloacetonitriles(HANs), and chloral hydrate(CH) was removed in sedimentation and biological activated carbon(BAC) filtration processes. However, DBPs were increased more or less by postchlorine step. In particular, the formation of THMs and HAAs depends on ozone more than chlorine, but, the formation of HANs and CH depends on chlorine more than ozone. The seasonal variation of DBPs concentration for the year needs to be investigated to study the temperature effect because DBPs strongly depend on temperature among various efficient factors.

Affixation of negative prefixes to a root or word derives a negative opposition of the original root or words. In case un-, dis- and de- are affixed to denominal verbs, privative oppositions are derived, and in case the prefixes are affixed to original verbs, reversative oppositions are derived. Generally, in-, non-, and a- are affixed to either nouns or adjectives, un- and dis- are affixed to nouns, adjectives, and verbs; de- is affixed to nouns or denominal verbs ending -ize and -fy. When prefix in- is affixed to a word, /n/ is assimilated to the initial sound of the word. This is from Latin but not English, and was applied to in-words before they were loaned from English. It must be pointed out that a diachronic approach will provide more descriptive power in analyzing English negative prefixes. They also claim that in the same context, in- is applied to level-1, un- is applied to level 2, and dis- is applied to both level 1 and level 2. The affixes which are affixed in level 2 are more productive and more meaningful. Though they didn't point out, the words combining with the level-1 affixes are originated from Latin or French, the words combining with the level-2 affixes are from Old English. However, some affixes are affixed to the bases and words in level 1 as well as in level 2. These affixes are usually Latin-based or French-based ones, They are affixed to OE-based words. The derivatives of Latin-based prefix plus OE-based word are as productive as the ones derived in level 2. Conversely, when some OE-based affixes can be affixed to Latin-based and French-based words, Ordering paradox might occur like in ungrammaticality. This means that a loan word is transferred to other languages in the finalized form, after it undergoes the phonological derivations of its original language. The two kinds of negation--negation by affixation of negative prefix to a word and syntactic negation--have the semantic interface with each other, but are not completely analogous semantically. Moreover, there is a difference among negative prefixes in implying either contrary negation or contradictory negation. When un-, dis- and de- are affixed to verbs, also, the derivatives have privative or reversative meaning.
