中國「禮樂」文明的內涵凸顯了與天地、制度、身心相合的連續性傾向。 因此, 探討禮樂文明的發展與意義, 對於彰明中國文明的價値, 實爲重要之事。 而新出土文獻<性自命出>的硏究, 在敍明中國禮樂文明的發展意義, 有其重要性。 因爲, <性自命出>中對於「禮樂」的討論, 旣觸及了古代儒學思想發展的軌跡, 也關乎中國禮樂文化的理論架構之意義, 尤其在「內在化」的方向上, <性自命出>對於「性」 「情」的討論, 更是具有階段轉變的意義, 可以釐淸儒學發展史的一些問題。 職是之故, 本文首先將從「禮樂」所涉及的幾個層次切入, 簡要說明禮樂在中國文化發展中的重要性。 其次, 則從<性自命出>的討論著眼, 處理此一文獻所涉及的禮樂問題。 最後, 說明<性自命出>在儒學史上的意義。 Investigations of Chinese ritualistic-musical culture demonstrate an unbroken tradition of harmony among heaven and earth, systems and regulations, and body and mind. It is therefore important to discuss the development and meaning of ritualistic-musical culture, in order to understand the contributions of Chinese culture. Research on the newly excavated document “Nature Derives from Mandates (Xing Zi Ming Chu)” (“Document”) is important for the understanding of development and meaning of ritualistic-musical culture. The Document not only deepens our understanding of the trajectory of the development of classical Confucianism, but also concerns the theoretical framework of the Chinese ritualistic-musical culture. The discussions of “nature” and “emotion” in the Document hold special significance in the transformation from one stage to another in terms of “internalization,” and shed light on some questions regarding the historical development of Confucianism. Therefore, this article first discusses the multiple dimensions of “Rituals and Music” and their importance in Chinese cultural development. Then, the article explores the implication of “Rituals and Music” discussions in the Document. Lastly, this article examines the significance of the Document in the history of Confucianism.

Ping-Hei Chen,Chin-Chi Hsu,Pei-Shan Lee,Chao-Sung Lin 대한기계학회 2011 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.25 No.1
This study successfully develops a versatile method of producing superhydrophobic surfaces with micro/nano-silica hierarchical structures on glass surfaces. Optically transparent super hydrophobic silica thin films were prepared by spin-coating silica particles suspended in a precursor solution of silane, ethanol, and H_2O with molar ratio of 1:4:4. The resulting super hydrophobic films were characterized by scanning electron microscopy (SEM), optical transmission, and contact angle measurements. The glass substrates in this study were modified with different particles: micro-silica particles, nano-silica particles, and hierarchical structures. This study includes SEM micrographs of the modified glass surfaces with hierarchical structures at different magnifications.

In total, forty six compounds, including the novel compound lobechine (1), were characterized from the methanol extracts of Lobelia chinensis. The chemical structures of known metabolites were identified by comparing their spectroscopic and physical data with compounds reported in the literature. The structure of lobechine (1) was comprehensively established with the aid of 1D and 2D NMR spectroscopic analyses. In addition, selected isolates were screened for their inhibition of HSV-1 replication, superoxide anion generation, and elastase release. Among the tested compounds, scoparone (10) exhibited significant inhibition of superoxide anion generation with IC_50 of 6.14 ± 1.97 μM and lobechine (1) exhibited moderate inhibition of elastase release with IC_50 of 25.01 ± 6.95 μM, respectively.

This study develops a statistical framework for characterizing an improved Buckypaper manufacturing process. A screening procedurebased on design of experiment techniques and the Lenth method was used to identify significant process parameters. These parameterssignificantly affect the tensile strength of the Buckypaper produced by the process. The procedure only samples a limited number ofexperimental runs. A linear regression model and a nonlinear model based on the Kriging method were constructed to characterizethe relationship between the parameters and tensile strength. Tradeoff curves were used to determine the best parameter settings whensimultaneously considering the mean and variance of the tensile strength. Validation tests show that both models are better predictorsthan previous models and the nonlinear model outperforms the linear model. The statistical framework provides a systematic andeffective method of characterizing the manufacture of nanotube products.
To Prevent Crack for Thin-wall Workpieces during Milling Process by Torque Feedback
Mu-Ping Tsai,Nan-Chyuan Tsai,Chun-Chi Lin,Hsin-Lin Chiu 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10
Thin-wall tubular-geometry workpieces have been widely applied in aircraft and medical industries. Though numerous research reports are available that the tool path can be planned on the basis of preset surface profile before actual milling operation is performed, it is still difficult to predict the real-time surface profile errors for peripheral milling of thin-wall tubular workpieces. This research is focused on how to real-time formulate the appropriate applied cutting torque via feedback of spindle motor current. A few suitable cutting conditions which are able to prevent potential break/crack of thin-wall workpieces and enhance productivity but almost retain the same cutting quality is proposed. To achieve this goal, estimated surface profile error on machined parts due to deflections caused by both tool and workpiece is studied. The torque estimation approach by spindle motor current feedback and the corresponding fuzzy logic controller are employed. Compared with constant cutting torque during milling operation in tradition manner, it is observed that the time consumption of milling cycle by aid of the aforesaid fuzzy logic controller is greatly shortened while the resulted cutting accuracy upon finish of workpiece can be almost retained.
IPO Underwriting and Subsequent Lending
Hsuan-Chi Chen,Li-Ping Chen,Keng-Yu Ho,Pei-Shih Weng 한국재무학회 2012 한국재무학회 학술대회 Vol.2012 No.09
This study investigates the relation between IPO underwriting and subsequent lending. We find that when a bank underwrites a firm’s IPO, the bank is more likely to provide the issuer with future loans at a lower cost, compared to banks without an IPO underwriting relationship. The evidence also suggests that the underwriting banks share information surplus with the IPO firms in the post-IPO loans, supporting the cost-saving hypothesis. Finally, when borrowing firms are more satisfied with the IPO outcomes, they are more likely to retain their underwriting banks as subsequent lenders. We find no evidence that underwriting banks would exploit such satisfaction by charging higher interest rates in the post-IPO loans.
Influence of the Incorporation of Aluminum on the Optical Properties of MCM-41
Ya-Ping Hsieh,Yang-Fang Chen,Ai-Qin Wang,Chi-Te Liang,Chung-Yuan Mou,Ji-Wei Chen 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.6
Different ratios of aluminum were incorporated into MCM-41. PL measurements revealed a blue shift and an enhancement in intensity by 2 orders of magnitude as the Si : Al ratio was decreased to 14. By comparing the PL and the photoluminescence excitation (PLE) spectra of aluminosilicate MCM-41 to silica MCM-41 and to published reports on similar materials, we are able to identify the origin of the photoluminescence enhancement.

BACKGROUND/OBJECTIVES: The objectives of this study were to investigate the effects of lycopene on the migration, adhesion, tube formation capacity, and p38 mitogen-activated protein kinase (p38 MAPK) activity of endothelial progenitor cells (EPCs) cultivated with high glucose (HG) and as well as explore the mechanism behind the protective effects of lycopene on peripheral blood EPCs. MATERIALS/METHODS: Mononuclear cells were isolated from human peripheral blood by Ficoll density gradient centrifugation. EPCs were identified after induction of cellular differentiation. Third generation EPCs were incubated with HG (33 mmol/L) or 10, 30, and 50 μg/mL of lycopene plus HG. MTT assay and flow cytometry were performed to assess proliferation and apoptosis of EPCs. EPC migration was assessed by MTT assay with a modified boyden chamber. Adhesion assay was performed by replating EPCs on fibronectin-coated dishes, after which adherent cells were counted. In vitro vasculogenesis activity was assayed by Madrigal network formation assay. Western blotting was performed to analyze protein expression of both phosphorylated and non-phosphorylated p38 MAPK. RESULTS: The proliferation, migration, adhesion, and in vitro vasculogenesis capacity of EPCs treated with 10, 30, and 50 μg/mL of lycopene plus HG were all significantly higher comapred to the HG group (P < 0.05). Rates of apoptosis were also significantly lower than that of the HG group. Moreover, lycopene blocked phosphorylation of p38 MAPK in EPCs (P < 0.05). To confirm the causal relationship between MAPK inhibition and the protective effects of lycopene against HG-induced cellular injury, we treated cells with SB203580, a phosphorylation inhibitor. The inhibitor significantly inhibited HG-induced EPC injury. CONCLUSIONS: Lycopene promotes proliferation, migration, adhesion, and in vitro vasculogenesis capacity as well as reduces apoptosis of EPCs. Further, the underlying molecular mechanism of the protective effects of lycopene against HG-induced EPC injury may involve the p38 MAPK signal transduction pathway. Specifically, lycopene was shown to inhibit HG-induced EPC injury by inhibiting p38 MAPKs.
