This study was carried out to have basic and applied informations to find the optimum nitrogen fertilization level for organic cultivation and to investigate early growth characteristics of Schizandra chinensis Baillon. Different application levels of the organic fertilizer were based on the recommended rate of N fertilizer. Five different levels of the organic fertilizer were applied to S. chinensis and early growth responses such as the length of vine, the diameter of vine, the number of leaves, and the number of branches were investigated. Lengths of main and total vines were shown longer at the level of 1.0 time organic fertilizer than those at others. The vine length at early growth was the highest at the level of 1.0 time organic fertilizer among the treatments. Stem diameter was shown thicker level of 1.0 time organic fertilizer than others on August and September, whereas on October it was the thickest in the conventional cultivation. Number of leaf was increased higher at the level of 1.0 and 2.0 times organic fertilizer than that in the compared to conventional. The number of branches was appeared the lowest at the level of 1.0 time organic fertilizer at early growth, however they were increased through progressing their growth stages. They were not significantly difference among the treatments except for the level of 2.0 times organic fertilizer. Based on the research results, the growth of S. chinensis was commonly higher at the level of 1.0 time organic fertilizer compared to other treatments.

Further Results on the Robust Stability for Neutral-type Lur’e System with Mixed Delays and Sector-bounded Nonlinearities

Wen-Yong Duan,Xiao-Rong Fu,Xiao-Dong Yang 제어·로봇·시스템학회 2016 International Journal of Control, Automation, and Vol.14 No.2

This paper is concerned with the robust stability for neutral-type Lur’e system with mixed time-varyingdelays. By combining the delay-fraction theory with the reciprocally convex method andWirtinger-based inequalitytechnology, some new delay-derivative-dependent stability criteria are derived via a modified Lyapunov-Krasovskiifunctional (LKF) approach. The criteria are less conservative than some previous ones.

A Brief Analysis on Five Elementary Components of Rousseau’s Romanticism

Wen Da,Kim Hoy-Yong 부산대학교 교육발전연구소 2016 교육혁신연구 Vol.26 No.1

The romantic ideology of Jean-Jacques Rousseau (1712 ~ 1778) firstly is a summary of his personal life experience, also the quintessence of his time spirit; moreover, it makes an outstanding contribution to the Enlightenment as well as the process of modernization theory. On one hand, it fills the deficiency of mainstream ideology of Enlightenment which is no longer confined to the rational and scientific knowledge; conversely, it strengthens the power of perception especially in art and religion, breaking new ground for widely releasing people’s inner creativity. On the other hand, the basic characteristic of romanticism emphasizes the emotions (or feelings) and becomes another mind-set that is from Rousseau, the father of romanticism, which is completely different from the rationalism of the Enlightenment. Rousseau’s romanticism is not ‘anti-rationality’, but ‘anti-intellectuality’ (i. e. a kind of rationalism in a narrow sense). This paper generalizes the core of Romanticism including the self-worship, appreciation of nature, expectations of dream, pursuit of emotion and obsession of language games. At the same time, it further analyzes what influences Rousseau’s Romanticism has made on literary creation and education in nineteenth and twentieth century. 루소의 낭만주의 사상은 루소 자신의 개인 생활 경험의 결과이며, 동시에 시대 정신의 산물이기도 하다. 루소의 낭만주의 사상은 근대화 이론뿐만 아니라 계몽사상에도 현저하게 기여하였다. 또한 계 몽주의 사상의 부족한 점을 보충하여, 이성과 과학의 지식에 더 이상 국한하지 않으면서, 계몽사상 에 감성적인 힘을 부여하였다. 루소의 낭만주의 사상은 개인에게 내재된 창의력을 발산하기 위해, 특히 예술과 종교에서의 지각의 힘을 강조하였다. 루소 낭만주의 사상의 또 다른 특징은 ‘감성의 강 조’에 있다. 루소의 낭만주의는 ‘이성’을 반대한 것이 아니라 ‘지성’(협의의 이성주의)을 반대하였다. 이 글은 자기-숭배, 자연에 대한 찬미, 꿈의 기대, 감성의 추구, 언어 게임의 집착 등 낭만주의의 핵 심 사상을 다루었다. 동시에 루소의 낭만주의가 19세기와 20세기의 문예 창작과 교육에 미친 영향력 을 분석하였다

New Robust Stability Criteria for Lur’e Systems with Time-varying Delays and Sector-bounded Nonlinearities

Wen-Yong Duan,Yan Li,Jian Chen,Baozhu Du 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.2

This paper deals with a robust stability problem for uncertain Lur’e systems with time-varying delays and sector-bounded nonlinearities. An improved delay-dependent robust stability criterion is proposed via a modified Lyapunov-Krasovskii functional (LKF) approach. Firstly, a modified LKF consisting of delay-dependent matrices and double-integral items under two delay subintervals is constructed, thereby making full use of the delay and its derivative information. Secondly, the stability criteria can be expressed as convex linear matrix inequality (LMI) via the properties of quadratic function application. Thirdly, to further reduce the conservatism of stability criteria, the quadratic generalized free-weighting matrix inequality (QGFMI) is used. Finally, some numerical examples, including the Lur’e system and the general linear time-delayed system, are presented to show the improvement of the proposed approach.

Effect of gelatin nano-coating containing Gardenia pigment on the preservation of pork slices

Yong Liu,Zi-Hao Liu,Chang-Qi Luo,Chun-Tao Xiao,Wen-Yu Zhou,Wen-Jin Xie 한국식품과학회 2022 Food Science and Biotechnology Vol.31 No.4

The nano-coating composed of gelatin and Gardenia pigment (GP) was successfully prepared and showed strong antioxidant activity. The average particle sizes of the nano-coating containing 0.1% and 0.3% GP were 269.58 and 394.13 nm, respectively. The pork slices uncoated and coated with the nano-coating were preserved at 4 C for 15 days. The pork slices’ pH, total volatile basic nitrogen (TVB-N), total viable counts (TVC), water-bind- ing capacity (WHC), and thiobarbituric acid reactive sub- stances (TBARS) were measured to assess the preservation effect of the nano-coating. The results showed that the pork coated with the nano-coating had lower pH, TVC, TVB-N, TBARS, and higher WHC, significantly different (p \ 0.05) than the uncoated pork. It is suggested that the proposed nano-coating can be used to effectively improve the pork’s quality and shelf life during refrigeration storage.

Self‐assembly of covalent porphyrin compound and its enhanced electrochemiluminescence performance

Wen-Kai Zhu,Wen-Rong Cai,Zhen-Zhi Yin,Ming-Jie Cheng,Kong Yong 대한화학회 2022 Bulletin of the Korean Chemical Society Vol.43 No.12

A novel Zn-coordination covalent porphyrin assembly (TCPP-BZA-Zn) is designed. The assembly structure is synthesized through the amidation reac- tion between the porphyrin terminal carboxyl group and the amino group of benzylamine (BZA), and further assembled through π–π stacking. In particular, the inherently ordered structure of TCPP-BZA-Zn with Zn as the catalytic active center endows the porphyrin assembly structure with several obvious advantages, such as high ion transport properties and high electrocatalytic per- formance. In the presence of hydrogen peroxide as a co-reaction reagent, TCPP-BZA-Zn/GCE showed excellent ECL behavior. The amplification phenome- non of ECL was further studied by cyclic voltammetry and the corresponding mechanism was proposed. Based on TCPP-BZA-Zn, an electrochemilumines- cence sensor was constructed for copper ion detection. The ECL intensity of the sensor shows a good linear relationship with the concentration of copper ion in the range of 10 nM–1 mM, and the detection limit is 1.3 nM.

Differential Impacts on Bacterial Composition and Abundance in Rhizosphere Compartments between Al-Tolerant and Al-Sensitive Soybean Genotypes in Acidic Soil

Wen Zhong-Ling,Yang Min-Kai,Fazal Aliya,Liao Yong-Hui,Cheng Lin-Run,Hua Xiao-Mei,Hu Dong-Qing,Shi Ji-Sen,Yang Rong-Wu,Lu Gui-Hua,Qi Jin-Liang,Zhi Hong,Qian Qiu-Ping,Yang Yong-Hua 한국미생물·생명공학회 2020 Journal of microbiology and biotechnology Vol.30 No.8

In this study, two soybean genotypes, i.e., aluminum-tolerant Baxi 10 (BX10) and aluminumsensitive Bendi 2 (BD2), were used as plant materials and acidic red soil was used as growth medium. The soil layers from the inside to the outside of the root are: rhizospheric soil after washing (WRH), rhizospheric soil after brushing (BRH) and rhizospheric soil at two sides (SRH), respectively. The rhizosphere bacterial communities were analyzed by high-throughput sequencing of V4 hypervariable regions of 16S rRNA gene amplicons via Illumina MiSeq. The results of alpha diversity analysis showed that the BRH and SRH of BX10 were significantly lower in community richness than that of BD2, while the WRH exhibited no significant difference between BX10 and BD2. Among the three sampling compartments of the same soybean genotype, WRH had the lowest community richness and diversity while showing the highest coverage. Beta diversity analysis results displayed no significant difference for any compartment between the two genotypes, or among the three different sampling compartments for any same soybean genotype. However, the relative abundance of major bacterial taxa, specifically nitrogen-fixing and/or aluminum-tolerant bacteria, was significantly different in the compartments of the BRH and/or SRH at phylum and genus levels, indicating genotype-dependent variations in rhizosphere bacterial communities. Strikingly, as compared with BRH and SRH, the WRH within the same genotype (BX10 or BD2) always had an enrichment effect on rhizosphere bacteria associated with nitrogen fixation

Improved Sufficient LMI Conditions for the Robust Stability of Timedelayed Neutral-type Lur’e Systems

Wen-Yong Duan,Baozhu Du,Yan Li,Cuifeng Shen,Xuelai Zhu,Xiaofan Li,Jian Chen 제어·로봇·시스템학회 2018 International Journal of Control, Automation, and Vol.16 No.5

In this paper, we focus on the problem of the absolute and robustly absolute stability for the neutraltype Lur’e system with time-varying delay. By combining the piecewise analysis theory with extended doubleintegral and Wirtinger-based inequalities technology, some new delay-dependent stability criteria for the absolute and robustly absolute stability are proposed via Lyapunov-Krasovskii functional (LKF) approach. The stability conditions can be expressed as convex linear matrix inequality (LMI) framework, which can be solved by using standard LMI convex optimization solvers. The criteria proposed in this paper are less conservative than some previous ones. Finally, some numerical examples are presented to show the effectiveness of the proposed approach.

Molecular characterization and expression analysis of putative odorant carrier proteins in Adelphocoris lineolatus

Yong Xiao,Liang Sun,Qi Wang,Qiang Zhang,Shao-Hua Gu,Adel Khashaveh,Ze-Wen Liu,Yong-Jun Zhang 한국응용곤충학회 2018 Journal of Asia-Pacific Entomology Vol.21 No.3

The alfalfa plant bug Adelphocoris lineolatus (Goeze) (Hemiptera: Miridae), a serious pest of several agricultural crops, is extremely attracted by flowering plants to perform season host switching. Generally, chemoreception of A. lineolatus plays a crucial role in detecting food sources, locating mates and oviposition sites. In addition, odorant carrier proteins are believed to participate in the initial chemical communication and perception in insects. In this work, we identified 31 putative odorant carrier protein genes from the antennal transcriptomes of A. lineolatus, including 17 new odorant binding proteins (OBPs), 10 new chemosensory proteins (CSPs) and four Niemann-Pick type C2 proteins (NPC2s). Phylogenetic analysis demonstrated that the OBP and CSP genes from four mirid bug species (A. lineolatus, Adelphocoris suturalis, Apolygus lucorum and Lygus lineolaris) had a relatively close evolutionary relationship. Regular patterns and key conserved motifs of OBPs and CSPs in Hemiptera insects are also identified by using Multiple EM for Motif Elicitation (MEME) tool. Tissue expression profiles analysis showed that nine of the 17 OBPs, 10 CSPs and two of the four NPC2s were primarily or uniquely expressed in the adult antennae suggesting their putative roles in chemoreception. Our study provides the first insight into the roles of odorant carrier proteins in chemoreception of A. lineolatus, which will help to facilitate biological functions of odorant carrier proteins and develop novel insect behavioral regulation strategy
