        朝鮮人視城中的乾隆皇帝 : 以《熱河日記》爲中心

        劉广銘,金英今 中韓人文科學硏究會 2008 한중인문학연구 Vol.24 No.-

        박지원 등이 창조한 건륭황제의 형상은 '객관화'됨으로써 동시대와 후세의 조선인들이 건륭황제를 묘사하는 데 있어서 원초적인 경험을 제공해주는 '기본 텍스트'로 작용하여 왔고 앞으로도 장기간에 걸쳐 건륭황제와 그 가족을 해석하는 기틀로 작용하게 될 것이다. 박지원이 묘사한 건륭황제는 조선조시기라는 역사적인 배경에서 이루어진 것인 동시에 박지원은 또한 조선조시기라는 역사적인 배경을 이루는 한 요소이기도 하다. 다시 말하면 사회집단의 상상력과 텍스트 사이의 관계는 전자가 후자를 제약하는 단선적인 영향관계가 아니라 양자가 서로 영향주는 관계, 일종의 교호적인 대화과정에 처해 있으며 부단한 대화과정에서 끊임없이 새로운 의의가 생성되고 새로운 형상이 탄생하게 되는 것이다. The objective image of Emperor Qianlong created by Pak Chi-Won is regarded as the pre-interpretation of the emperor. Such an image not only made the foundation for those Koreans in the same and following periods but also constrained the followers' interpretation of Qianlong and his family for a long time. Though the interpretation of Qianlong by Pak Chi-Won was constrained in the context of Li Dynasty, his interpretation also contributed to the creation of the context. It means the relation between virtual world of the community and text is not that the former one influences and constrains the later one but they interact with each other. They have an iterative dialogue relation. In such iterative dialogues new meanings and new images are continuously created.

        Influence of an Oxide Interlayer Dielectric (ILD) Capping Layer on the Thermal Stability of Ni Germanide for Nanoscale Ge MOSFETs

        Ying-Ying Zhang,In-Shik Han,Shi-Guang Li,Soon-Yen Jung,박기영,신홍식,Ga-Won Lee,왕진석,이희덕,오정우,Prashant Majhi,Raj Jammy 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.55 No.3

        In this research, the influence of an interlayer dielectric (ILD) capping layer on the thermal stability of Ni germanide was analyzed. The Ni germanide was formed on a Ge-on-Si substrate by using a one-step rapid thermal process (RTP) at 400 ˚C for 30 sec. We found little difference in the X-ray diffraction (XRD) results, but the proposed structure with oxide ILD capping layer showed better thermal immunity than that without one. Adopting an oxide ILD capping layer resulted in a lower sheet resistance, less surface roughness, and less Ni germanide agglomeration and penetration after high temperature post-germanidation annealing at 500 ˚C. Therefore, oxide capping is promising for improving the thermal stability of Ni germanide for nanoscale germanium metal oxide semiconductor field effect transistors (Ge MOSFETs).

        The Correlation between the Injury Patterns of the Medial Patellofemoral Ligament in an Acute First-Time Lateral Patellar Dislocation on MR Imaging and the Incidence of a Second-Time Lateral Patellar Dislocation

        Guang-ying Zhang,Hong-xia Zhu,En-miao Li,Hao Shi,Wei Liu,Lei Zheng,Zheng-wu Bai,Hong-yu Ding 대한영상의학회 2018 Korean Journal of Radiology Vol.19 No.2

        Objective: To evaluate the correlation between the injury patterns of the medial patellofemoral ligament (MPFL) on magnetic resonance imaging in an acute first-time lateral patellar dislocation (LPD) and incidence of a second-time LPD. Materials and Methods: Magnetic resonance images were prospectively analyzed in 147 patients after an acute first-time LPD with identical nonoperative management. The injury patterns of MPFL in acute first-time LPDs were grouped by location and severity for the analysis of the incidence of second-time LPD in a 5-year follow-up. Independent t tests, chi-square tests and Kruskal-Wallis tests were performed as appropriate. Results: Forty-six cases (46/147, 31.3%) of second-time LPD were present at the 5-year follow-up. Fourteen (14/62, 22.6%) and 31 cases (31/80, 38.8%) were present in the partial and complete MPFL tear subgroups, respectively. Twenty-five cases (25/65, 38.5%), 11 cases (11/26, 42.3%), and 8 cases (8/47, 17%) were present in the isolated femoral-side MPFL tear (FEM), combined MPFL tear (COM), and isolated patellar-side MPFL tear (PAT) subgroups, respectively. Compared with the partial MPFL tears, complete tears showed higher incidence of a second-time LPD (p = 0.04). The time interval between the two LPDs was shorter in the complete MPFL tear subgroup (24.2 months) than in the partial tear subgroup (36.9 months, p = 0.001). Compared with the PAT subgroup, the FEM and COM subgroups showed a higher incidence of a second-time LPD (p = 0.025). The time intervals between the two LPDs were shorter in the FEM and COM subgroups (20.8 months and 19.2 months) than in the PAT subgroup (32.5 months, p = 0.049). Conclusion: A complete MPFL tear, isolated femoral-side tear and combined tear in a first-time LPD predispose a second-time LPD.

        Stress Dependence of Thermal Stability of Nickel Silicide forNano MOSFETs

        Ying-Ying Zhang,Won-Jae Lee,Zhun Zhong,Shi-Guang Li,Soon-Yen Jung,이가원,왕진석,이희덕,Sung-Kyu Lim 한국전기전자재료학회 2007 Transactions on Electrical and Electronic Material Vol.8 No.3

        Dependence of the thermal stability of nickel silicide on the film stress of inter layer dielectric (ILD) layer has been investigated in this study and silicon nitride (Si3N4) layer is used as an ILD layer. Nickel silicide was formed with a one-step rapid thermal process at 500 oC for 30 sec. 2000 Å thick Si3N4 layer was deposited using plasma enhanced chemical vapor deposition after the formation of Ni silicide and its stress was split from compressive stress to tensile stress by controlling the power of power sources. Stress level of each stress type was also split for thorough analysis. It is found that the thermal stability of nickel silicide strongly depends on the stress type as well as the stress level induced by the Si3N4 layer. In the case of high compressive stress, silicide agglomeration and its phase transformation from the low-resistivity nickel mono-silicide to the high-resistivity nickel di-silicide are retarded, and hence the thermal stability is obviously improved a lot. However, in the case of high tensile stress, the thermal stability shows the worst case among the stressed cases.

        Improvement of Thermal Stability of Ni Germanide Using a Ni–Pt(1%) Alloy on Ge-on-Si Substrate for Nanoscale Ge MOSFETs

        Ying-Ying Zhang,Jungwoo Oh,Shi-Guang Li,Soon-Yen Jung,Kee-Young Park,Ga-Won Lee,Majhi, P.,Hsing-Huang Tseng,Jammy, R.,Hi-Deok Lee IEEE 2010 IEEE TRANSACTIONS ON NANOTECHNOLOGY Vol.9 No.2

        <P>In this paper, thermally stable Ni germanide using a Ni-Pt(1%) alloy and TiN capping layer is proposed for high-performance Ge MOSFETs. The proposed Ni-Pt(1%) alloy structure exhibits low-temperature germanidation with a wide temperature window for rapid thermal processing. Moreover, sheet resistance is stable and the germanide interface shows less agglomeration despite high-temperature postgermanidation anneal up to 550 <SUP>°</SUP>C for 30 min. In addition, the surface of the Ni-Pt(1%) alloy structure is smoother than that of a pure Ni structure both before and after the postgermanidation anneal. Only the NiGe phase and no other phases such as Pt<SUB>x</SUB>Ge<SUB>y</SUB> and Ni<SUB>x</SUB>Pt<SUB>1-x</SUB>Ge<SUB>y</SUB> can be observed in X-ray diffraction results, but X-ray photoelectron spectroscopy shows that PtGe is formed during the postgermanidation anneal. The larger Pt atomic radius is believed to inhibit the diffusion of Ni into the Si substrate, thereby improving the thermal stability of the NiGe. The higher melting point of PtGe is also believed to improve thermal stability. Therefore, this proposed Ni-Pt(1%) alloy could be promising for high-mobility Ge MOSFET applications.</P>

        Purification and Biochemical Characterization of a Novel Fibrinolytic Enzyme from Streptomyces sp. P3

        ( Guang Yan Cheng ),( Li Ying He ),( Zhi Bin Sun ),( Zhong Li Cui ),( Ying Xiang Du ),( Yi Kong ) 한국미생물 · 생명공학회 2015 Journal of microbiology and biotechnology Vol.25 No.9

        A novel proteolytic enzyme with fibrinolytic activity, FSP3, was purified from the recently isolated Streptomyces sp. P3, which is a novel bacterial strain isolated from soil. FSP3 was purified to electrophoretic homogeneity by ammonium sulfate precipitation, anion exchange, and gel filtration. FSP3 is considered to be a single peptide chain with a molecular mass of 44 kDa. The maximum activity of the enzyme was observed at 50°C and pH 6.5, and the enzyme was stable between pH 6 and 8 and below 40°C. In a fibrin plate assay, FSP3 showed more potent fibrinolytic activity than urokinase, which is a clinical thrombolytic agent acting as a plasminogen activitor. The activity was strongly inhibited by the serine protease inhibitor PMSF, indicating that it is a serine protease. Additionally, metal ions showed different effects on the activity. It was significantly suppressed by Mg2+ and Ca2+ and completely inhibited by Cu2+, but slightly enhanced by Fe2+. According to LC-MS/MS results, its partial amino acid sequences are significantly dissimilar from those of previously reported fibrinolytic enzymes. The sequence of a DNA fragment encoding FSP3 contained an open reading frame of 1287 base pairs encoding 428 amino acids. FSP3 is a bifunctional enzyme in nature. It hydrolyzes the fibrin directly and activates plasminogen, which may reduce the occurrence of side effects. These results suggest that FSP3 is a novel serine protease with potential applications in thrombolytic therapy.

      • Thermal Immune NiGermanide for High Performance Ge MOSFETs on Ge-on- Si Substrate Utilizing <tex> $ \hbox{Ni}_{0.95}\hbox{Pd}_{0.05}$</tex> Alloy

        Ying-Ying Zhang,Jungwoo Oh,In-Shik Han,Zhun Zhong,Shi-Guang Li,Soon-Yen Jung,Kee-Young Park,Hong-Sik Shin,Won-Ho Choi,Hyuk-Min Kwon,Wei-Yip Loh,Majhi, P.,Jammy, R.,Hi-Deok Lee IEEE 2009 IEEE transactions on electron devices Vol.56 No.2

        <P>Highly thermally stable Ni germanide technology for high performance germanium metal-oxide-semiconductor field-effect transistors (Ge MOSFETs) is proposed, utilizing Pd incorporation into Ni germanide. The proposed Ni germanide shows not only the improvement of thermal stability but also the reduction of hole barrier height, which can improve the device on-current by reducing the Ni germanide to p+ source/drain contact resistance. The proposed Ni germanide showed a stable sheet resistance of up to 500 degrees C 30-min postgermanidation annealing due to the suppression of agglomeration and oxidation of Ni germanide and the diffusion of Ni and Ge atoms by the incorporated Pd. Therefore, the proposed Ni0.95Pd0.05, alloy could be promising for the high mobility Ge MOSFET applications.</P>

      • Cyr61/CCN1 Overexpression Induces Epithelial-Mesenchymal Transition Leading to Laryngeal Tumor Invasion and Metastasis and Poor Prognosis

        Liu, Ying,Zhou, Yan-Dong,Xiao, Yu-Li,Li, Ming-Hua,Wang, Yu,Kan, Xuan,Li, Qiu-Ying,Lu, Jian-Guang,Jin, De-Jun Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.7

        Background: To examine the expression of cysteine-rich 61 (Cyr61/CCN1) protein in laryngeal squamouscell carcinoma (LSCC) tissues, and its relationship with the tumor epithelial-mesenchymal transition (EMT), invasion, metastasis, and prognosis. Materials and Methods: Immunohistochemistry was used to detect the expressions of Cyr61, Vimentin (Vim), and E-cadherin (E-cad) in 88 cases of LSCC tissues and 30 cases of tumor-adjacent normal tissues. Vim and E-cad were used as mesenchymal and epithelial markers, respectively, to determine the relationship between Cyr61 expression and the EMT of LSCC cells. In addition, clinical and histopathological data were combined to analyze the relationship between the positive-expression rates of Cyr61, Vim and E-cad and LSCC invasion, metastasis and prognosis. Results: In LSCC tissues, Vim expression rate was significantly higher than that of the tumor-adjacent tissues, whereas E-cad expression rate was significantly lower than that of the tumor-adjacent tissues. The Vim expression rate was significantly higher in stages T3 and T4 than in stages T1 and T2 LSCC tissues, whereas E-cad expression rate was significantly lower in stages T3 and T4 than in stages T1 and T2 LSCC tissues. Compared to the group without lymph node metastasis, the Vim expression rate was significantly higher and the E-cad expression rate was significantly lower in the group with lymph node metastasis. The expression rate of Cyr61 was significantly higher in LSCC tissues than in the tumor-adjacent normal tissues. In addition, the Cyr61 expression rate was higher in stages T3 and T4 than in stages T1 and T2 LSCC, and higher in the group with lymph node metastasis than in the group without lymph node metastasis. The Vim expression rate was significantly higher in the Cyr61 positive group than in the Cyr61 negative group, whereas the E-cad expression rate was significantly higher in the Cyr61 negative group than in the Cyr61 positive group. Survival analysis indicated that survival rates of Cyr61 positive, Vim positive and E-cad negative groups were significantly lower than that of Cyr61 negative, Vim negative and E-cad positive groups, respectively. Conclusions: Cyr61 expression is closely associated with LSCC invasion and lymph node metastasis. Overexpression of Cyr61 may induce EMT and therefore leads to LSCC invasion and metastasis and poor prognosis. Cyr61 may become a new maker for clinical prediction of LSCC invasion and metastasis and a new target for LSCC treatment.
