The rapid development of information technology makes people"s lifestyles constantly changing, bringing great changes to the library building. As a product of the development of public libraries, community libraries have an important impact on community cohesion and revitalization through providing targeted learning and leisure services to residents. Under the trend of social and community development, the community library"s user-centered space must adapt to the diverse needs of community users and make the self-improvement. First of all, this study summarizes the concept of community and community libraries through literature review, and then make a theoretical investigation on the composition of user-centered space. Finally this study bases on the cases of community library buildings in the United States and Britain, and initially explores the composition of user-centered space in these libraries, and then analyzes and summarizes the architectural characteristics of it. Exploring how community can be activated and cohesive through community libraries user-centered space. Hope that this study can provide some reference to the contemporary community library design.

On Uncertain Probabilistic Data Modeling

Teng Lv,Ping Yan,Weimin He 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.12

Uncertainty in data is caused by various reasons including data itself, data mapping, and data policy. For data itself, data are uncertain because of various reasons. For example, data from a sensor network, Internet of Things or Radio Frequency Identification is often inaccurate and uncertain because of devices or environmental factors. For data mapping, integrated data from various heterogonous data sources is commonly uncertain because of uncertain data mapping, data inconsistency, missing data, and dirty data. For data policy, data is modified or hided for policies of data privacy and data confidentiality in an organization. But traditional deterministic data management mainly deals with deterministic data which is precise and certain, and cannot process uncertain data. Modeling uncertain data is a foundation of other technologies for further processing data, such as indexing, querying, searching, mapping, integrating, and mining data, etc. Probabilistic data models of relational databases, XML data and graph data are widely used in many applications and areas today, such as World Wide Web, semantic web, sensor networks, Internet of Things, mobile ad-hoc networks, social networks, traffic networks, biological networks, genome databases, and medical records, etc. This paper presents a survey study of different probabilistic models of uncertain data in relational databases, XML data, and graph data, respectively. The advantages and disadvantages of each kind of probabilistic modes are analyzed and compared. Further open topics of modeling uncertain probabilistic data such as semantic and computation aspects are discussed in the paper. Criteria for modeling uncertain data, such as expressive power, complexity, efficiency, extension are also proposed in the paper.

High Capacity Information Hiding Method Based on Pixel-value Adjustment with Modulus Operation

( Teng Li Yu Zhang ),( Sha Wang ),( Jun-jie Sun ) 한국인터넷정보학회 2021 KSII Transactions on Internet and Information Syst Vol.15 No.4

Through information hiding technique, secret message can be hidden in pictures. Stego-image quality and hiding capacity are two important metrics for information hiding. To enhance these metrics, many schemes were proposed by scholars in recent years. Some of them are effective and successful, but there is still a room for further improvement. A high capacity information hiding scheme (PAMO, Pixel-value Adjustment with Modulus Operation Algorithm) is introduced in this paper. PAMO scheme uses pixel value adjustment with modulus operation to hide confidential data in cover-image. PAMO scheme and some referenced schemes are implemented in Python and experiments are carried out to evaluate their performance. In the experiments, PAMO scheme shows better performance than other methods do. When secret message length is less than 72000 bits, the highest hiding capacity of PAMO can reach 7 bits per pixel, at the same time the PSNR of stego-images is greater than 30 dB.

Mechanism of nitrogen-fluoride co-doped TiO2/bentonite composites removing tetracycline: A study in the co-doping ratio

Teng WANG,Zhaofu MENG,Xinxin WANG,Amjad ALI,Xuewen CAO,Lin LIU 대한환경공학회 2021 Environmental Engineering Research Vol.26 No.6

N-doped and N-F co-doped TiO2/bentonite composites were synthesized via the gel-sol method. The morphology, structure and surface charge of the composite before and after adsorption were used to determine the effect N/F doping ratio on TC removal. The results showed that, compared with undoped samples, the TC adsorption on N doped composites was reduced by 24.44% on average. N-F co-doping significantly increased the TC adsorption when the Ti-N-F molar ratio was 1:1: 0.01, reaching a maximum TC adsorption of 64.00 mmol·kg−1. The coverage of the N doped TiO2 increases as the N doping ratio increases; the specific surface area increased by 2.03 % on average, but the number of surface negative charges decreased by 36.24 % on average. FT-IR results confirmed that N doping reduced the number of -OH groups on the N-doped composites. Additionally, fluorination of N-F co-doped TiO2 and bentonite surfaces inhibits hydrogen bonding and π-π interactions between the TC and the composites. As the N doping ratio increased, the coverage of N-F co-doped TiO2 on the composite surface increased, resulting in the TC adsorption decrease with the increases N doping ratio.

Tic21 is an essential translocon component for protein translocation across the chloroplast inner envelope membrane.

Teng, Yi-Shan,Su, Yi-shin,Chen, Lih-Jen,Lee, Yong Jik,Hwang, Inhwan,Li, Hsou-min American Society of Plant Physiologists 2006 The Plant cell Vol.18 No.9

<P>An Arabidopsis thaliana mutant defective in chloroplast protein import was isolated and the mutant locus, cia5, identified by map-based cloning. CIA5 is a 21-kD integral membrane protein in the chloroplast inner envelope membrane with four predicted transmembrane domains, similar to another potential chloroplast inner membrane protein-conducting channel, At Tic20, and the mitochondrial inner membrane counterparts Tim17, Tim22, and Tim23. cia5 null mutants were albino and accumulated unprocessed precursor proteins. cia5 mutant chloroplasts were normal in targeting and binding of precursors to the chloroplast surface but were defective in protein translocation across the inner envelope membrane. Expression levels of CIA5 were comparable to those of major translocon components, such as At Tic110 and At Toc75, except during germination, at which stage At Tic20 was expressed at its highest level. A double mutant of cia5 At tic20-I had the same phenotype as the At tic20-I single mutant, suggesting that CIA5 and At Tic20 function similarly in chloroplast biogenesis, with At Tic20 functioning earlier in development. We renamed CIA5 as Arabidopsis Tic21 (At Tic21) and propose that it functions as part of the inner membrane protein-conducting channel and may be more important for later stages of leaf development.</P>

Teng, Shu-Hua,Wang, Peng,Kim, Hyoun-Ee Elsevier 2009 Materials letters Vol.63 No.28

<P><B>Abstract</B></P><P>A novel fibrous system, chitosan/agarose, was successfully developed via the electrospinning of their blend solutions. The trifluoroacetic acid (TFA)/dichloromethane (DCM) mixture was used as a suitable solvent for both chitosan and agarose. It was found that smooth, continuous fibers were generated at an agarose content of less than 50%. Moreover, with the increase of the agarose content from zero to 50%, the average diameter of the fibers was significantly decreased from about 1.76 to 0.14μm. The FT-IR analysis revealed a gradual shift of the absorption band in the blend fibers, suggesting the strong interaction and good compatibility between chitosan and agarose.</P>

Teng, Shu‐,Hua,Lee, Eun‐,Jung,Yoon, Byung‐,Ho,Shin, Du‐,Sik,Kim, Hyoun‐,Ee,Oh, Joong‐,Soo Wiley Subscription Services, Inc., A Wiley Company 2009 Journal of biomedical materials research. Part A Vol.a88 No.3

<P><B>Abstract</B></P><P>Chitosan/hydroxyapatite (HA) composite membranes were prepared by the coprecipitation method and a subsequent dynamic filtration and freeze‐drying process. The influences of the HA content of the membranes on their phase and morphology, mechanical properties, and bioactivity were investigated. FTIR analysis revealed that chitosan and HA had good miscibility over a wide range of compositions. Needle‐like HA nanocrystals with low crystallinity were uniformly embedded in the chitosan matrix. As the HA content was increased, the tensile strength of the membranes exhibited a steady decrease, while the elastic modulus increased by a factor of 2 when 20% HA was added. The results of the <I>in vitro</I> cell culture showed that the highest alkaline phosphatase level was achieved when 30% HA was contained in the composites. © 2008 Wiley Periodicals, Inc.

Teng, Hui,Ghafoor, Kashif,Choi, Yong-Hee The Korean Society for Applied Biological Chemistr 2009 Applied Biological Chemistry (Appl Biol Chem) Vol.52 No.6

Active components in Chinese quince were extracted by using high efficient microwave-assisted extraction. In accordance with central composited design, 20 runs with 3 variables and 5 levels applied for the optimization in response surface methodology system. The extracts were analyzed by spectrophotometeric methods for the total flavonoids content (TFC), total phenolic compound (TPC) and electron donating ability (EDA). The optimum conditions obtained were 44.15% ethanol concentration, 5 min extraction time and 102.1 W microwave power for maximum TFC (477.8 mg RE/100 g), TPC (2249 mg GAE/100 g) and EDA (77.47%) as predicted by overlaid contour plots.

Optimization of Ultrasonic-assisted Extraction of Phenolic Compounds from Chinese Quince (Chaenomeles sinensis) by Response Surface Methodology

Teng, Hui,Jo, In-Hee,Choi, Yong-Hee The Korean Society for Applied Biological Chemistr 2010 Applied Biological Chemistry (Appl Biol Chem) Vol.53 No.5

Functional phenolic compounds were extracted from Chinese quince using highly efficient ultrasonic-assisted extraction (UAE) technology. The experiment was carried out in accordance with a small central composite design (SCCD) five-level and three-variable approach. The optimum combination of solvent concentration, extraction temperature and time with the application of ultrasonic, for the maximum extraction of phenolic compounds from Chinese quince, was obtained by response surface methodology. Responses of phenolic compounds such as total phenolics, total flavonoids, and total flavan-3-ols were determined by the spectrophotometer assay. High significance of each response revealed that this SCCD model well-fitted the experimental parameters as well as the reliability of the predicted value. The optimal UAE conditions obtained by superimposed contour plot were 50% ethanol concentration, $63.9^{\circ}C$ extraction temperature, and extraction time 11.4 min. Under the above-mentioned conditions, the experimental results for three responses were total phenolic content 2367.16 mg gallic acid equivalents /100 g, total flavonoid content 544.12 mg rutin equivalents /100 g, and total flavan-3-ols content 709.07 mg catechin equivalents /100 g, which well-matched with the predicted values. The optimal conditions attained from the present study would provide scientific references to economical production of relative phenolic compounds products.
