Effect of Brewing Conditions on Taste Components of Keemun Black Tea
Eunhye Kim,Haibo Pan,Xiao Mao,Guangwei Wang,Yuanyuan WU,Youying Tu 한국차학회 2015 한국차학회지 Vol.- No.S
Tasting and quality components of tea infusion are the important standard of tea quality. The chemicals of tea infusion influent the sanitarian function and quality, and also are key factors of products for consumers. The effects of brewing time and temperature on extractability of Keemun black tea were studied. The results showed that the contents of tea polyphenols, theaflavins, thearubigins and caffeine were obviously affected by temperature at 80℃, however, no significant effect on the other components. The results also showed that the TP/AA ratio content, suggested that 80℃ boiling water could brew best taste in Keemun black tea.

The Development of Clinical Document Standards for Semantic Interoperability in China
Peng Yang,Feng Pan,Danhong Liu,Yongyong Xu,Yi Wan,Haibo Tu,Xuejun Tang,Jianping Hu 대한의료정보학회 2011 Healthcare Informatics Research Vol.17 No.4
Objectives: This study is aimed at developing a set of data groups (DGs) to be employed as reusable building blocks for the construction of the eight most common clinical documents used in China’s general hospitals in order to achieve their structural and semantic standardization. Methods: The Diagnostics knowledge framework, the related approaches taken from the Health Level Seven (HL7), the Integrating the Healthcare Enterprise (IHE), and the Healthcare Information Technology Standards Panel (HITSP) and 1,487 original clinical records were considered together to form the DG architecture and data sets. The internal structure, content, and semantics of each DG were then defined by mapping each DG data set to a corresponding Clinical Document Architecture data element and matching each DG data set to the metadata in the Chinese National Health Data Dictionary. By using the DGs as reusable building blocks, standardized structures and semantics regarding the clinical documents for semantic interoperability were able to be constructed. Results: Altogether, 5 header DGs, 48 section DGs, and 17 entry DGs were developed. Several issues regarding the DGs, including their internal structure, identifiers,data set names, definitions, length and format, data types, and value sets, were further defined. Standardized structures and semantics regarding the eight clinical documents were structured by the DGs. Conclusions: This approach of constructing clinical document standards using DGs is a feasible standard-driven solution useful in preparing documents possessing semantic interoperability among the disparate information systems in China. These standards need to be validated and refined through further study.

Impact of Grafting Density on the Self-Assembly and Hydrophilicity of Succinylated Collagen
Wenxin Wang,Feiyi Shu,Lingyu Pan,Shanshan Huang,Xiao Tu,Ping Li,Siman Li,Yuanyuan Li,Chengzhi Xu,Yang Sun,Juntao Zhang,Haibo Wang 한국고분자학회 2020 Macromolecular Research Vol.28 No.6
Modification of protein could give their new functionality but would affect their intrinsic property and activity. In this paper, a series of succinylated collagen (SCol(n/1)) (n≥1) were prepared by modification of collagen with succinic anhydride at different molar ratio to amino groups amount of collagen. The impact of grafting density on the intrinsic self-assembly and additional hydrophilicity of succinylated collagen was explored. The results revealed that excessive grafting density of succinylated collagen would improve their hydrophilicity but weaken their self-assembly property, although the triple helix of collagen could be reserved after succinylation. SCol(1/1) (grafting density of 17%) with self-assembly property and good hydrophilicity was chosen to compare with native collagen. Compared to native collagen, thermostability of SCol(1/1) decreased slightly, however, SCol(1/1) could form softer hydrogel, which was more favorable for the proliferation of NIH/3 T3. The present work would help us to further understand the importance of grafting density for the design of modified collagen with intrinsic self-assembly property and additional new functionality.

Computational design towards energy efficient optimization in overconstrained robotic limbs
Gu Yuping,Wang Ziqian,Feng Shihao,Sun Haoran,Lu Haibo,Pan Jia,Wan Fang,Song Chaoyang 한국CDE학회 2023 Journal of computational design and engineering Vol.10 No.5
Legged robots are constantly evolving, and energy efficiency is a major driving factor in their design. However, combining mechanism efficiency and trajectory planning can be challenging. This work proposes a computational optimization framework for optimizing leg design during basic walking while maximizing energy efficiency. We generalize the robotic limb design as a four-bar linkage-based design pool and optimize the leg using an evolutionary algorithm. The leg configuration and design parameters are optimized based on user-defined objective functions. Our framework was validated by comparing it to measured data on our prototype quadruped robot for forward trotting. The Bennett robotic leg was advantageous for omni-directional locomotion with enhanced energy efficiency.
