This characterizes the Kim chun-su`s poem Duˇl-rim, Dostoevski(1997) and chair and stairs(1999)-through metonymic reading. The 1990`s is the period that postmodern symptoms conspicurously appear in arts and culture. His poems have both contemporary universality, which is postmodern and the experimetal mind that the very method of composing a poem show a thought. The postmodrn symptoms in his poems is shown off in deconstructing aspect. The deconstruction in a formal aspect-deconstructing a discription system and a completed narration-indicates the recognition that the universe is indeterminable, incidental and relative. If metaphor and metonymy are extended as one of the ways recognizing this universe, his poems show the metonymic recognition. D??l-rim. Dostoevski has intertxstuality with Dostoevski`s novels and poems prior to Kim. Kim`s poems have a unique description system which delays meanings. It removes `Signified` and `Signified` turns another `Signifer`. This description system reflects the aspects that the meanig is open, not finished. In chair and stairs, the historical and ordinary narration has no totality. A metonynic image intrudes, breaking and transferring a poetic meanig and acts as fragmenting the narration. Tihs means a denial of history.

又峰 趙熙龍의 梅花圖

金志善(Kim Jisun) 미술사연구회 2007 미술사연구 Vol.- No.21

In the Late Joseon Dynasty, the cultural environment of the capital, Hanseong, was clearly different from that of other provinces, and connoisseurship became popular among admirers of antique works of Chinese calligraphy or paintings seeking to express their loftiness and refinement. Moreover, the demand for artistic works increased greatly. Most studies have estimated that Jo Huiryong(1789~1866), a painter who was well-known for his plum blossom paintings in the 19th century, was influenced by Kim Jeonghui. Although Kim Jeonghui was an influential leader among painters, the works of middle class artists including Jo seem to have been painted to suit the taste of collectors. Jo's plum blossom paintings show richer and more magnificent pictorial images, unlike the classical literati representatives of Kim's. Because Jo rarely dated his own works, it is difficult to categorize them chronologically. As such, this study classifies almost all of his works by size and categorizes them vertically hanging scrolls of plum blossoms, small size leaf paintings, and panoramic view of plum blossoms in a form of screen panels. In his narrow vertical type of works, Jo attempted to express a sense akin to stone inscription calligraphy, by representing the twisted branches of plum trees with strong, sharp, and straight lines similar to the calligraphic style. He also painted many small leaf paintings using ink in an improvised painting style of the classical literati. Moreover, he started to produce huge panoramic plum screen panels for the first time during the Joseon period. In particular, Jo's panel works are characterized by their grand size and spectacular images. He focused on the expressive potentials of brush and ink, projecting his personal interpretation of the painted subject. Jo adapted the style of the Yangzhou School while developing his own style, and became influential among his contemporaries and to the painters of the next generation. Jo's plum blossom paintings are not only emblems of the literati's classical painting but also ideal ink plum images that represent the artist as a solitary creator.

Due to increase in demand of stable and long pipelines in natural gas industry, wide range of researches are being performed on automation welding to improved welding quality with respect to weld process parameters in real time measurement. In particular, the coupling between the pipe manufacturing process and location of the weld seam, the measured size of the gap that exists in the weld position and the weld angle depending on whether the movement of molten weld. This is due to absence of controlling welding penetration position, depending on the required size of the angle of the setting. In addition, the optimum welding conditions must be considered while selecting, the correlation between these variables and the systematic correlation has not yet been identified. Therefore, in most welded pipe root-pass weld solely depends on the experience of workers in relation to secure a stable weld quality. In this study, automation welding system is implemented to select a suitable root-pass STT (Surface Tension Transfer) welding method using the optimal welding conditions. To successfully accomplish this objective, there were various welding conditions used for welding experiment to confirm that the assessment required for construction through the pipe and automatic welding process is proposed to optimize this plan.

The edentulous posterior maxilla generally provides a limited amount of bone height because of atrophy of the ridge and pneumatization of the maxillary sinus, Maxillary sinus augmentation is one of the surgical techniques for reconstruction of the severely resorbed posterior maxilla. The purpose of this study was to evaluate the survival rate of implants and the long-term changes of graft height after maxillary sinus augmentation by lateral window approach. From September 1996 to July 2004, maxillary sinus augmentation with mixed grafts of autograft, allograft, xenograft and alloplast were performed on 45 patients and 100 implants were placed. We evaluated the survival rate of implants and the changes of BL(bone length)/IL(implant length) according to time using panoramic radiographs. The survival rate of implants was 91.0% for follow-up period. The mean reduction of graft heights was 0.34mm(3.0%) for 6 months and 1.22mm(1O.66%) for 3 years after augmentation. The total mean BL/IL was $1.34{\pm}0.21$ during 5 year observation period after augmentation and decreased slightly over time. The result means that graft materials were stable above the implant apex. BL/ILs of 1stage procedure were significantly decreased at 1-2 year, 3-4 year after augmentation and no statistically significant changes were observed in those of 2 stage procedure. The graft materials of both procedures were stable above the implant apex. No statistically significant changes of BL/IL were observed in the grafts combined with low amount of autogenous bone or without autogenous bone. The graft materials of both groups were stable above the implant apex. The results indicated that the placement of dental implants with maxillary sinus augmentation showed predictable clinical results and the grafts combined with low amount of autogenous bone or without autogenous bone had long-term resistance to resorption in maxillary sinus.

목적:본 연구에서는 long internal connection 형태의 임플란트 지대주를 내부 연결 길이에 변화를 주어 임플란트-지대주 결합부의 안정성을 비교 평가해 보고자 하였다. 재료 및 방법: Long internal connection의 임플란트(Replus system, $4.7{\times}11.5mm$)를 각각 지대주의 길이에 따라 4개의 군(1, 2, 3, 4 mm 군)으로 나누었고 총 20개의 시편을 사용하였다. 시편을 레진에 매몰하여 고정시키고 100 N의 힘으로 임플란트 장축에 대해 30도의 각도에서 $1.0{\times}10^6$ 번의 반복하중을 가한 후 하중 전 후의 풀림회전력의 차이를 계산하여 95% 유의수준에서 Kruskal-Wallis 검정 방법을 통해 통계 분석하였다. 결과:지대주 내부 길이에 따른 풀림 회전력의 통계적 유의성은 나타나지 않았으며 (P > .05) 어떤 시편에서도 완전한 나사 풀림이나 나사 파절은 관찰되지 않았다. 결론: 내측 연결 임플란트에서 지대주 내부길이에 따른 나사 풀림의 정도는 차이가 나지 않았다. Purpose: The purpose of this study was to evaluate whether the internal abutment length affected screw stability in an internal connection implant. Materials and methods: Twenty long internal connection implants (Replus system, $4.7{\times}11.5mm$) were selected for this investigation. Abutments were assigned to four groups depending on the length of the internal connection (abutments with internal lengths of 1, 2, 3, and 4 mm, respectively). Each implant fixture specimen was embedded in resin medium and connected to an abutment with an abutment screw. A load of 100 N, applied at an angle of $30^{\circ}$ to the long axis of the implant, was repeated for $1.0{\times}10^6$ cycles. Reverse torque values (RTV) were recorded before and after loading, and the change in RTV was calculated. Data were analyzed with the Kruskal-Wallis test. Results: The change in RTV was not significantly different among the groups (P>.05). Screw loosening and fractures were not observed in any groups, and joint stability was maintained. Conclusion: The internal length of the abutment may not significantly affect the degree of screw loosening.

To investigate the performance of the composite carbon electrodes which the ion exchange polymers were directly casted onto porous carbon electrode surfaces, the adsorption/desorption experiments were carried out by varying the feed concentration, feed flow rate, and desorption voltages for the NaCl solution. When the feed concentration was 100 mg/L, the increase of the adsorption time led to the increase of the salt removal due to the increase of the residence time inside the cell while the increase of the feed flow rate from 15 mL/min to 23 mL/min gave the decrease of the salt removal efficiency, 12% because of the short residence time. When the feed concentration was 200 mg/L, the salt removal was shown 10~15% low because of the incomplete desorption within the desorption intervals. 다공성 전극표면에 이온교환고분자를 직접 casting하여 만들어진 복합탄소전극의 성능을 알아보기 위해서 NaCl 수용액을 이용하여 흡착시간, 공급액 농도, 유속, 탈착전압에 따라 흡/탈착실험을 진행하였다. 유입수가 100 mg/L일 때 동일 조건에서 흡착시간이 3분에서 5분으로 증가하면서 제거율이 3% 증가하였는데 이는 유입수의 셀 내부 잔류시간의 증가로 인한 것으로 사료되며 또한 유속이 15 mL/min에서 23 mL/min 증가하면서 효율이 12% 정도 낮음을 보인 것은 유속이 상승하면서 유입수의 셀 내부 잔류시간이 짧아지면서 나타나는 영향으로 사료된다. 유입수의 농도를 200 mg/L로 증가하였을 때 효율은 100 mg/L보다 10~15% 정도 낮은 값을 보였는데, 이는 탈착구간에서 완전탈착이 되지 않아 나타나는 것으로 판단된다.

To improve efficiency of solar cells, it is important to make a light trapping structure to reduce surface reflectance for increasing absorption of sun light within the solar cells. One of the promising methods that can reduce surface reflectance is isotropic texturing with acid solution based on hydrofluoric acid(HF), nitric acid($HNO_3$), and organic additives. Anisotropic texturing with alkali solution is not suitable for multicrystalline silicon wafers because of its different grain orientation. Isotropic texturing with acid solution can uniformly etch multicrystalline silicon wafers unrelated with grain orientation, so we can get low surface reflectance. In this paper, the acid texturing solution is made up of only HF and $HNO_3$ for easy controlling the concentration and low cost compared to acid solution with organic additives. $HNO_3$ concentration and dipping time were varied to find the condition of minimum surface reflectance. Textured surfaces were observed Scanning Electron Microscope(SEM) and surface reflectance were measured. The best result of arithmetic mean(wavelength from 400 nm to 1000 nm) reflectance with acid texturing is 4.64 % less than alkali texturing.

This study investigated the changes in representation on analogies that elementary science-gifted students generated by using Algodoo program to explain the electric current. After the students were taught about the 'components in circuit and their function' and 'electric current' with teacher centered analogy and PhET program for 4 class hours, they generated analogies to the electric circuit. Then they compared the similarity between generated analogy and target concept and matched it to the target concept. The result revealed that the battery, light bulb, and electric wire were changed according to the change of representations on free electrons. And they generated more proper analogies reflected the target concept when represented the free electrons by the circular particles than the water. From these results, we can say that generating analogy using Algodoo program is the effective education activity to help students understand abstract concept by visualizing it more easily and simply.
