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.

김춘수 시의 환유적 읽기

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.

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.

Purpose: The purpose of the present study was to compare the effects of both general hold-relax techniques and hold-relax techniques using pumping on pain due to delayed muscle pain and on the range of motion (ROM) of joints. Methods: Thirty-nine young adult males and females were randomly assigned either to a hold-relax technique application group of 20 subjects or to a group of 19 subjects with hold-relax techniques applied using a pumping application. Tenderness thresholds, the ROM of joints, and pain intensities were measured on the biceps of the nondominant arm of the subjects in both groups before exercises were performed to induce delayed muscle pain. Tenderness thresholds were again measured 24hours, 48hours, and 72 hours after inducing delayed muscle pain. The relevant intervention methods were applied to the two groups after conducting the measurement at 48hours. As a statistical analysis method, repeated measure ANOVAs were conducted to examine the tenderness thresholds, ROMs of elbow joints, and pain intensities in the individual groups at the time points. Results: At 48 hours and 72 hours after application of the interventions, the general hold-relax technique application group showed greater changes in the tenderness thresholds, the ROMs of elbow joints, and the pain intensities than did the group applying hold-relax techniques using a pumping application (p>0.05). Conclusion: Based on the results of the present study, the application of hold-relax techniques is thought to have beneficial effects on pain resulting from delayed muscle pain and on limited ROMs of joints.

교합의 점진적인 마모는 연령이 증가함에 따라 진행되는 정상적인 과정이다. 하지만 교합면의 마모가 과도하게 진행되어 수직 교합 고경이 감소하고 교합 평면이 붕괴된 경우에는 병적인 치수 상태, 교합 부조화, 기능적 장애 및 심미적인 문제가 나타날 수 있다. 치아를 수복할 공간이 부족하거나 교합 관계를 수정하기 위해서는 수직 교합 고경의 변경이 필요하다. 수직 고경을 변화시킬 경우, 수복 치료를 시작하기 전에 신중한 진단이 필수적이며 1 - 3개월 간 임시 수복물을 이용하여 근 신경계의 적응 범위를 벗어나지 않는지 평가를 한 후 최종 수복을 하여야 한다. 본 증례의 환자는 다수 치아들의 심한 마모가 있는 78세 남성 환자로서 수직 교합 고경의 평가 후 상악 전치부의 심미적인 외형 확보 및 교합관계, 교합평면의 개선을 위하여 최소한의 수직교합고경의 거상을 통하여 임시치아를 제작, 약 12주간의 적응기간 후 최종수복물을 제작하였다. 최종 수복물 장착 후 1년여의 경과 관찰 결과 새로 형성한 교합이 안정적으로 유지되었으며 특이할만한 합병증은 없었다. 이러한 일련의 치료과정을 통해 심미적, 기능적으로 만족할 만한 결과를 얻었기에 이를 보고하는 바이다. The progressive attrition of teeth is a normal process by aging. However, excessive tooth wear with decreased vertical dimension of occlusion and collapse of occlusal plane may cause pathologic pulpal condition, occlusal disharmony, functional disorders and esthetic problems. The change of vertical dimension is required in case that there is no sufficient clearance for restoration or in case that the occlusal relationship is modified. For gaining the vertical dimension, a careful diagnosis is essential prior to starting the restoration treatment. After evaluating adaptation of neuromuscular system of patient during provisional phase, the final restorations can be fabricated. In this case, a 78 year old male with severely worn down dentition was treated. To improve the esthetic appearance and to achieve the ideal occlusal relationship, the full mouth rehabilitation with minimal increase of vertical dimension is planned and diagnostic wax-up was performed at the increased vertical dimension. After evaluation of provisional restorations for 12 weeks, final restorations were fabricated and routine clinical assessments were made. After 1 year, the restorations with newly established occlusal scheme are well maintained without significant complications and esthetically and functionally satisfactory results were obtained.

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.
