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

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.

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.

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.

송어 간세포와 생쥐 간세포에서 TCDD가 CYP1A1 유전자 발현에 미치는 영향 비교 연구

김지선,민경난,신윤용,Kim, Ji-Sun,Min, Kyung-Nan,Sheen, Yhun-Yhong 한국환경성돌연변이발암원학회 2004 한국환경성돌연변이·발암원학회지 Vol.24 No.3

In mammalian, cytochrome P4501A1 (CYP1A1) is very important for metabolism of xenobiotics such as PAHs(Polycyclic aromatic hydrocarbon) and heterocyclic amine, and it is induced by environmental contaminants such as PAHs, TCDD(2,3,7,8-tetrchlorodibenzo-p-dioxin) and 3-MC (3-methylcholanthrene). In fish, like mammalian, when it is exposed to environmental contaminants, they cause specific and sensitive induction of CYP1A. Therefore, induction of CYP1A in fish and mammalian is widely used as a biomarker for exposure of environmental contaminants. In this study, to compare the function of Cyp1a1 in fish with it in mammalian, we have used rainbow trout(Oncorhynchys mykiss) hepatoma cells (RTH-149) and mouse hepatocyte (Hepa-I). in order to examine induction of Cyp1a1 by TCDD, we have used the bioassay system. We examined effects of TCDD on the Cyp1a1-luciferase reporter gene activity, 7-ethoxyresorufin O-deethylase(EROD) activity and Cypa mRNA level.

Interpretation of Teacher Knowledge in Geometry with Shulman - Fischbein Framework: Cases of US Preservice Teachers

김지선,Kim, Ji Sun The Korean School Mathematics Society 2018 韓國學校數學會論文集 Vol.21 No.2

많은 사람들이 교수에서 교사의 지식이 중요다고 동의하고, 이에 대해 많은 연구들이 정량적인 접근 방식을 사용하여 잘 가르치기 위해 교사가 갖추어야 할 지식의 요소와 특징을 규명하려고 시도하였다. 이러한 기존의 연구들과는 달리 본 논문은 기하 영역에서 예비 교사의 지식을 정성적인 방법으로 Shulman-Fischbein 개념틀을 활용하여 해석하는 방법을 제안한다. 7명의 여 예비교사들이 본 연구에 자원하여 참여하였고, 각 예비교사는 지필 형식으로 된 일련의 과제를 수행하였다. 수집된 예비교사의 지식은 수학적 알고리즘적 SMK, 형식적 SMK, 직관적 SMK, 알고리즘적 PCK, 형식적 PCK, 직관적 PCK로 분석되었다. 해결결과 예비 교사들은 강한 SMK를 갖고 있고, 그들의 뿌리깊게 자리잡은 SMK는 변하지 않으며, 그들의 SMK와 PCK는 상당한 관련이 있고, 그들은 학생에 대한 지식과 관련하여 적절한 PCK를 갖고 있지만, 교수학적 전략을 제시함에 있어 직관적 PCK에 상대적으로 덜 고려하는 경향을 보였다. Shulman-Fischbein 개념틀을 활용하여 분석해 드러난 예비교사들의 지식은 향후 교사 양성 프로그램을 계획하는데 도움을 줄 수 있을 것이다. There is no doubt about the importance of teacher knowledge for good teaching. Many researches attempted to conceptualize elements and features of teacher knowledge for teaching in a quantitative way. Unlike existing researches, this article suggests an interpretation of preservice teacher knowledge in the field of geometry using the Shulman - Fischbein framework in a qualitative way. Seven female preservice teachers voluntarily participated in this research and they performed a series of written tasks that asked their subject matter knowledge (SMK) and pedagogical content knowledge (PCK). Their responses were analyzed according to mathematical algorithmic -, formal -, and intuitive - SMK and PCK. The interpretation revealed that preservice teachers had overally strong SMK, their deeply rooted SMK did not change, their SMK affected their PCK, they had appropriate PCK with regard to knowledge of student, and they tended to less focus on mathematical intuitive - PCK when they considered instructional strategies. The understanding of preservice teachers' knowledge throughout the analysis using Shulman-Fischbein framework will be able to help design teacher preparation programs.

전통 단청안료 표면의 물리적 특성 변화 모니터링

김지선,정혜영,변두진,유민재,김명남,이선명,Kim, Ji Sun,Jeong, Hye Young,Byun, Doo-Jin,Yoo, Min Jae,Kim, Myoung Nam,Lee, Sun Myung 한국문화재보존과학회 2020 보존과학회지 Vol.36 No.6

석간주, 진사, 황토, 자황, 웅황, 석록, 뇌록, 석청 및 백토 등 천연 무기안료 9종의 성능과 수명을 평가하고자 실내 촉진내후성과 옥외폭로 시험을 수행하였다. 실내 촉진내후성 시험법은 국내 기후 특성 및 단청의 위치 환경을 반영하여 설계하였고 필드 재현성을 확인하기 위해 서울 숭례문과 대전 연구소 등 2개소에서 옥외폭로 시험을 병행하였다. 또한 누적 자외선량을 기준으로 안료 표면의 물리적 특성 변화를 모니터링하였다. 이 결과, 석간주와 백토는 초기에 미세균열이 발생하지만 안정화된 반면 진사와 석록은 균열이 지속적으로 확대되었다. 황토와 뇌록은 수분 및 송진에 의한 얼룩이 두드러졌고 자황, 웅황 및 석청은 입자의 광택 저하가 나타났다. 각 시험별 안료의 색 변화는 절대적인 수치 차이가 있을 뿐 색도 변화 양상은 유사하였다. 백토와 뇌록의 색차(𝚫E) 값이 5 이하로 가장 작고 진사는 28 이상으로 컸다. 안료 표면의 물리적 변화는 실내 촉진내후성 시험보다는 옥외폭로 시험이, 옥외폭로 시험에서는 대전 연구소보다 서울 숭례문에서 가중되었다. 이는 옥외폭로 시험이 큰 폭의 온·습도 변화, 분진 침적에 따른 오염 등 다양한 환경에 노출되고, 특히 서울 숭례문은 총 누적 자외선량(334 MJ/m²)에 도달하는 데까지 오랜 시간이 소요되어 노출 기간이 장기화되었기 때문이다. This study aimed to assess the performance and life of nine natural mineral dancheong pigments: Seokganju, Jinsa, Hwangto, Jahwang, Wunghwang, Seokrok, Noerok, Seokcheong, and Baekto. The design of the accelerated weathering test considered the domestic climate characteristics and the location of Dancheong. Outdoor weathering tests were conducted at the Research Institute in Daejeon and the Sungnyemun Gate in Seoul to confirm the field reproducibility of the accelerated weathering test. Monitoring of the physical changes in pigments through accelerated and outdoor weathering tests are based on ultraviolet exposure dose. Despite small cracks at the beginning of the tests, the monitoring showed that Seokganju and Baekto had no marked physical changes, but the surface cracks of Jinsa and Seorok continue to expand. Hwangto and Noerok were marked with water or were resin stained, and the particles of Jahwang, Wunghwang, and Seokcheong had lost their luster. Despite the absolute difference in color change in each test, the final chromaticity change patterns of pigments were similar in that the color difference between Baekto and Noerok was below five, and Jina was above 28. The physical and surface color pigment changes were more concentrated in outdoor weathering tests than in accelerated tests, and the Seoul site was more intense than the Daejeon site. This is because outdoor weathering tests are exposed to severe variations of temperature and moisture or deposition of dust particles and, in the case of Seoul, the site is more exposed to the external environment than the Daejeon site.

북극-동아시아 지역의 봄철 온난화가 북극 진동-한국의 황사 사례일의 종관 기상에 미치는 영향 분석

김지선,조재희,김학성,Ji-Sun Kim,Jae-Hee Cho,Hak-Sung Kim 한국지구과학회 2024 한국지구과학회지 Vol.45 No.2

1991-2020년의 30년 동안 봄철(3-5월)에 북극-동아시아 지역의 지표면 부근 대기 온난화가 북극 진동에 따라 한국의 서울에서 발생하는 황사 사례일의 종관 기상 특성에 미치는 영향을 분석하였다. 북극-동아시아 지역의 봄철 온난화 증가는 한국의 서울에서 황사 사례일을 6일을 감소시켰고, 황사 사례일의 PM₁₀ 질량 농도도 -1.6 ㎍ m^-3yr^-1으로 강도를 약화시키는데 기여하고 있었다. 2010년대 한국에서 감소하고 있는 황사 사례일에 대한 동아시아 지역의 종관 기상 특성은 음(-)의 잠재소용돌이도(Potential Vorticity Unit; PVU)로 나타나는 고기압성 활동이 증가하고 있었다. 또한, 한국에서는 음(-)의 북극진동지수(Arctic Oscillation Index; AOI)에서 황사 사례일이 증가하고 양(+)에서는 감소하는 정적 편포를 보였다. AOI가 음(-)인 황사 사례일에서는 중국 대륙에 온난한 고기압이 강화되고 있었다. 더불어 한대 제트의 중심 위치가 북쪽으로 이동하면서 몽골과 중국 북부에서는 한대 기단의 남하에 의한 저기압성 활동이 약해지고 있었다. 황사의 발생이 감소하였을 뿐 아니라 발원지로부터 한국으로 황사를 수송하는 풍속이 감소하고 있었다. 반면, AOI가 양(+)인 황사 사례일에서는 중국 대륙에 광역적으로 온난하고 정체적인 고기압이 위치하고 있었으며, 한대 제트의 북쪽이 더욱 냉각되어 있었다. 몽골-중국 북부-한국에 이르는 지역에서 하층 대류권의 현저한 풍속 감소가 황사 발생을 감소시킬 뿐 아니라 장거리 수송을 약화시키는 원인이 되는 것으로 보인다. This study examined the influence of near-surface atmospheric warming in the Arctic-East Asia region during spring (March-May) from 1991 to 2020 on the synoptic-scale meteorology of dust storm-induced dust days in Seoul, Korea, in response to the Arctic Oscillation. Increased springtime warming in the Arctic-East Asia region correlated with a reduction of six days in the occurrence of dust storm-induced dust days in Seoul, Korea, along with a decline in the intensity of these days by -1.6 ㎍ m^-3yr^-1 in PM₁₀ mass concentration. The declining number of dust storm-induced dust days in Korea during the 2010s was the result of synoptic-scale meteorological analysis, which showed increased high-pressure activity as indicated by the negative potential vorticity unit. Moreover, a distinct pattern emerged in the distribution of dust storm-induced dust days in Korea based on the Arctic Oscillation Index (AOI), showing an increase in negative AOI and a decrease in positive AOI. Although the northward shift of the polar jet weakened the southerly low-pressure system activity over Mongolia and northern China, a reinforced high-pressure system formed over the Chinese continent during dust-storm-induced dust days with a negative AOI. This resulted in both a decrease in the frequency of dust-storm-induced dust days and reduction in wind speeds, facilitating their transport from source regions to Korea. Conversely, on days with positive AOIs, an extensive warm and stagnant high-pressure system dominated mainland China, accompanied by further cooling of the northern segment of the polar jet. A notable decline in wind speed in the lower troposphere across the Mongolia-northern China-Korea region diminished the occurrence of dust storm-induced dust days and also weakened their long-range transport.
