이한민 ( Lee Han-min ),조은영 ( Cho Eun-young ) 국어학회 2015 국어학 Vol.74 No.-

This paper tries to figure out the additory usage of final ending ‘-ge’―the semantic function of [supposition] and [assumption inducement]― as an extension to the grammaticalization process of final ending ‘-ge,’ originated from a connective ending ‘-ge’ organized by Cho, Eun-Young & Lee, Han-Min (2011). The sentence structure of [supposition] ‘-ge’ is consisted of the antecedent clause, which is a conditional clause, and the following clause ‘-ge’ clause, and is used as a rhetorical interrogative of an ironic statement denying the antecedent clause. It also shows some correlation with [completion result] ‘-ge’, considering the fact that ‘-ge’ can be combined with the tense prefinal ending ‘-eoss-’, and that following ‘-ge’ clause cannot be used by itself, and that the following clause can emphasize the antecedent clause semantically. The sentence structure of [assumption inducement] ‘-ge’ is often used when inducing a listener to make an assumption of a matter that a speaker already knows. However, it is not used as a question to get a new information from the listener although it may be used in a form of a wh-question or an alternative question. [Assumption inducement] ‘-ge’ clause shows some similar meaning with that of a [completion result] ‘-ge’ clause regarding the fact that it can be combined with the tense prefinal ending ‘-eoss-’ and that this clause is about something that has already happened or determined. However, it shows some differences in that whether this sentence structure can be used alone or its focus point of utterance is on ‘-ge’ clause itself. There exists several similarities between [supposition] and [completion result] in syntactic and semantic context, in addition to a transitional phase in which a sentence is used as a [supposition] clause when sentence structures exhibit identical features to [completion result]. Thus, it can be seen that [supposition] is a connecting stage following the [completion stage]. In case of [assumption inducement], there exists several similarities between [assumption inducement], [completion result] and [supposition] in syntactic and semantic context. However, the authors were not able to draw a definitive conclusion as to whether [assumption inducement] can be dealt with changing meanings of semantic functions of final ending ‘-ge,’ organized in Cho, Eun-Young & Lee, Han-Min (2011). Thus, there is an implied possibility that [Assumption inducement] may not be a grammaticalized final ending ‘-ge’ but that of different origins with dissimilar semantic functions. In the synchronic use, however, it is certain that [assumption result] ‘-ge’ has a definitive correlation with semantic functions of final endings that are grammaticalized in the connective ending ‘-ge.’

N₂O is hazardous atmosphere pollution matter which can damage the ozone layer and cause green house effect. There are many other nitrogen oxide emission control but N₂O has no its particular method. Preventing further environmental pollution and global warming, it is essential to control N₂O emission from industrial machines. In this study, the thermal decomposition experiment of N₂O gas mixture is conducted by using cylindrical reactor to figure out N₂O reduction and NO formation. And CHEMKIN calculation is conducted to figure out reaction rate and mechanism. Residence time of the N₂O gas in the reactor is set as experimental variable to imitate real SNCR system. As a result, most of the nitrogen components are converted into N2. Reaction rate of the N₂O gas decreases with N₂O emitted concentration. At 800℃ and 900℃, N₂O reduction variance and NO concentration are increased with residence time and temperature. However, at 1000℃, N₂O reduction variance and NO concentration are deceased in 40s due to forward reaction rate diminished and reverse reaction rate appeared.

목적: 난치성 녹내장 환자에 시행한 공막경유 다이오드레이저 섬모체광응고술이 시력에 미치는 영향을 알아보고자 하였다. 대상과 방법: 공막경유 다이오드레이저 섬모체광응고술을 시행하고 6개월 이상 추적관찰이 가능했던 148명 148안의 의무기록을 후향 적으로 분석하였으며, 시술 전 시력이 ‘광각 있음’ 이상인 49명(1군)과 ‘광각 없음’이었던 99명(2군)으로 분류하여 섬모체광응고술 후 시력 변화를 포함한 임상결과를 분석하였다. 결과: 평균 추적관찰 기간은 1군은 19.1 ± 13.5개월, 2군은 16.7 ± 12.7개월이었다. 1군과 2군에서 안압( p <0.001), 안압하강제의 수( p <0.001)는 유의하게 감소하였다. 전체 환자에서 시술 전 최대교정시력은 2.4 ± 0.9 logMAR에서 시술 후 2.5 ± 0.8 logMAR로 유의한 변화는 없었지만( p =0.612), 1군에서는 1.4 ± 1.0 logMAR에서 1.9 ± 1.1 logMAR로 통계적으로 유의하게 감소하였다( p <0.001). 1군의 31안(63.3%)에서는 시술 후 0.2 logMAR 이상의 시력저하가 관찰되었고, 이들 중 15안(30.6%)에서는 광각소실이 발생하였다. 전체 환자에서 합병증으로는 각막부종이 5안(3.4%)에서 관찰되었고, 안구로, 만성 저안압이 각각 3안(2.0%), 포도막염이 2안(1.4%)에 서 발생하였다. 결론: 난치성 녹내장 환자에서 공막경유 다이오드레이저 섬모체광응고술은 안압하강 목적으로 유용하게 사용될 수 있지만 시력이 있는 환자에서는 유의한 시력저하를 유발할 수 있다는 점을 염두에 두어야 하겠다. Purpose: To evaluate the effects of trans-scleral diode laser cyclophotocoagulation (TSDLC) on best corrected visual acuity (BCVA) in patients with refractory glaucoma. Methods: The medical records of 148 eyes of 148 patients with refractory glaucoma who were followed-up for over 6 months af-ter TSDLC were analyzed retrospectively. Among them, 49 eyes of 49 subjects who had BCVA greater than no light perception (NLP) before TSDLC were classified as Group 1 and the other 99 eyes of 99 patients who had NLP vision were classified as Group 2. The outcomes of TSDLC including change in BCVA following surgery were analyzed for all patients and 49 subjects. Results: The mean follow-up period in Group 1 was 19.1 ± 13.5 months and 16.7 ± 12.7 months in Group 2. The intraocular pres-sure (IOP) and the number of IOP lowering medications decreased in both groups (both p < 0.001). In all subjects, there was no significant difference between BCVA before surgery and at the last follow-up (2.4 ± 0.9 log MAR and 2.5 ± 0.8 log MAR, re-spectively, p = 0.612). However, in Group 1, BCVA was decreased from 1.4 ± 1.0 to 1.9 ± 1.1 log MAR after the TSDLC (p < 0.001). In those patients, visual loss ≥ 0.2 log MAR was found in 31 eyes (63.3%) and light perception was lost in 15 eyes (30.6%). After treatment, corneal edema developed in 5 eyes (3.4%), phthisis bulbi and chronic hypotony occurred in 3 eyes each (2%) and iri-docydlitis occurred in 2 eyes (1.4%). Conclusions: TSDLC in patients with refractory glaucoma showed an efficient reduction in IOP and the number of IOP-lowering medications. However, there was a significant loss in BCVA in many patients and therefore, careful monitoring regarding poten-tial visual loss is necessary when considering TSDLC in glaucoma patients with useful vision.

This paper presents the RC-Bank installation by its optimal location and design to reduce harmonics on the Korean high-speed railway system. The system model of the Korean high-speed railway system is based on 8-port representation, which is an extension of 2-port network theory. A new proposed model is for harmonic analysis in 2×27.5㎸ traction power supply system including feeders, contact lines, rails and autotransformers. The proposed model is developed by combining fundamental element models of the Korean high-speed railway system, and it is verified by comparing simulation results with measurement data regarding the amplification rate of harmonic currents.

Six thousands of vehicles are operated on Korean urban transit system. 95% of them have regeneration system. Especially, the VVVF-Inverter vehicle has a merit of the highest regeneration rate. Therefore, the energy storage system is needed to be developed to use regeneration energy when the vehicle is braking. Therefore, Measuring regeneration energy in the substation need to know how much regeneration energy occurs, how much capacity of energy storage system is needed. After measuring regeneration energy, we design the capacity of energy storage system.

Purpose: To report a case of full thickness macular hole associated with rupture of retinal arterial macroaneurysm. Case summary: A 84-year-old female presented with 1-week history of decreased vision in the left eye. She had poorly controlled hypertension. On the initial examination, the best corrective visual acuity (BCVA) was 0.8 in the right eye and finger count 30 cm in the left eye. Both eyes had nucleoscleosis and cortical opacity. A fundus examination detected a sub-internal limiting membrane (ILM) premacular hemorrhage and small vitreous hemorrhage with a subretinal hemorrhage. Fluorescein angiography and indocyanine green angiography revealed a hot spot of retinal arterial macroaneurysm at superotemporal branch retinal artery. Hourglass patterned hemorrhage related with retinal arterial macroaneurysm was diagnosed. 23 gauge vitrectomy was performed to remove sub-ILM hemorrhage and if needed and possible, removal of subretinal hemorrhage was planned. After core vitrectomy, sub-ILM hemorrhage was confirmed, and partial ILM peeling was done. After removal of sub-ILM hemorrhage, full thickness macular hole was observed. More ILM was peeled, fluid gas exchange was done. Anatomic closure of the macular hole was achieved after the operation and was confirmed by optical coherence tomography examination. Two months after surgery, her vision had improved to 0.3. Conclusions: Macular hole which found during surgery was associated with rupture of retinal arterial macroaneurysm. A full-thickness macular hole occurred at the same time as retinal arterial macroaneurysm ruptured. Early surgery should be considered for retinal arterial macroaneurysm casuing all layers retinal hemorrhages need early surgery

The brake control system is designed using the adaptive sliding mode control scheme to realize a robust anti-slip brake control. From the result of computer simulations, improvement of braking performance is verified. On the other hand, the pneumatic brake systems for railway rolling stocks contain uncertainties such as compressibility of the air, elastic deformation of the caliper, and variation of friction coefficient between brake disk and pad which is concerned with the rising temperature and protrusion of the disk surface caused by the wear or being invaded foreign substance. In this study, the reference velocity of the rolling stocks during braking time is set by considering design parameters of the rolling stock. The model following control method is proposed for the reference velocity tracking. The feed-forward control input is calculated using the value of being measured deceleration. The sliding mode controller is used as a feed-back controller of model following controller. From the results of computer simulations, it is proven that proposed model following controller can compensate the uncertainties in the pneumatic brake system, especially the variation of friction coefficient between brake disk and pad.
