Without Rice, Even the Cleverest Housewife Cannot Cook: Sustainable Livelihoods Research in a Poor Chinese Village

Ling Zhong1, Megan Blaxland2 and Ting Zuo1 한국사회복지학회 2015 Asian Social Work and Policy Review Vol.9 No.1

This paper presents findings of a qualitative study investigating the assets, the risks and shocks, and the anti-risk mechanisms of the households of a poor village in rural northern China. The paper explores the vulnerability of the rural households to becoming impoverished and presents some implications for Chinese social policy. The research shows that income sources and assets of the households were considerably varied, and that this, in turn, affected the kinds of strategies they could implement to manage risk. Poorer households had fewer assets, smaller social networks, and less capacity to manage risk than better-off households, despite all living in the same poor village. Moreover, poorer households were much more likely to have family members with chronic ill-health or disability. These findings point to a need to ensure better access for all rural households to social support, health and care services, and opportunities to find new sources of income within their village.

Baihua Village is a typical mountainous village in the southwest part of Lujiang county, Longyang District, Baoshan City, Yunnan Province. Residents there made a living on the land, including growing sugarcane and planting maize, whose annual income was no more than 2000 yuan before 2006. Since then when a research institute has set it as one of the pilot villages for mango growing impetus with sci-tech. For the sake of “One village and One Product”, mango breeding and relevant techniques have been applied to daily work. Within years, the developed model of has been explored: simply “villages are the main carriers facilitated by the specialized cooperative for mango growing, back-up by science and technology. Technical trainings serve as the driving force for the leading growers, meanwhile, sellers work as the bridge link the producing-end and the markets”.

STRUCTURAL AND SPECTRAL PROPERTIES OF k-QUASI-*-PARANORMAL OPERATORS

ZUO, FEI,ZUO, HONGLIANG The Kangwon-Kyungki Mathematical Society 2015 한국수학논문집 Vol.23 No.2

For a positive integer k, an operator T is said to be k-quasi-*-paranormal if ${\parallel}T^{k+2}x{\parallel}{\parallel}T^kx{\parallel}{\geq}{\parallel}T^*T^kx{\parallel}^2$ for all x $\in$ H, which is a generalization of *-paranormal operator. In this paper, we give a necessary and sufficient condition for T to be a k-quasi-*-paranormal operator. We also prove that the spectrum is continuous on the class of all k-quasi-*-paranormal operators.

EXISTENCE AND EXPONENTIAL STABILITY OF ALMOST PERIODIC SOLUTION FOR SHUNTING INHIBITORY CELLULAR NEURAL NETWORKS WITH DISTRIBUTED DELAYS AND LARGE IMPULSES

Zuo, Yi,Wang, Yaonan,Huang, Lihong,Li, Chunsheng Korean Mathematical Society 2009 대한수학회지 Vol.46 No.5

This paper considers the problem of existence and exponential stability of almost periodic solution for shunting inhibitory cellular neural networks with distributed delays and large impulses. Based on the contraction principle and Gronwall-Bellman's inequality, some sufficient conditions are obtained. The results of this paper are new and they complement previously known results.

Moisture Sorption and Thermodynamic Properties of Vacuum-Dried Capsosiphon fulvescens Powder

Zuo, Li,Rhim, Jong-Whan,Lee, Jun Ho The Korean Society of Food Science and Nutrition 2015 Preventive Nutrition and Food Science Vol.20 No.3

The moisture sorption isotherms of vacuum-dried edible green alga (Capsosiphon fulvescens) powders were determined at 25, 35, and $45^{\circ}C$ and water activity ($a_w$) in the range of 0.11~0.94. An inversion effect of temperature was found at high water activity (>0.75). Various mathematical models were fitted to the experimental data, and Brunauer, Emmett, and Teller model was found to be the most suitable model describing the relationship between equilibrium moisture content and water activity (<0.45). Henderson model could also provide excellent agreement between the experimental and predicted values despite of the intersection point. Net isosteric heat of adsorption decreased from 15.77 to 9.08 kJ/mol with an increase in equilibrium moisture content from 0.055 to $0.090kg\;H_2O/kg$ solids. The isokinetic temperature ($T_{\beta}$) was 434.79 K, at which all the adsorption reactions took place at the same rate. The enthalpy-entropy compensation suggested that the mechanism of the adsorption process was shown to be enthalpy-driven.

Intensity modulation-based fibre optic vibration sensor using an aperture within a proof mass

Zuo, Ze-Wei,Hao, Yi,Choi, Sang-Jin,Song, Minho,Kim, Young-Chon,Pan, Jae-Kyung IET 2017 IET science, measurement & technology Vol.11 No.1

<P>The authors propose an intensity modulation-based fibre optic vibration sensor (FOVS) using an aperture within a proof mass. It consists of an optical collimator, a mass-spring structure, a mirror, and a rectangular aperture. They verify its feasibility via experimental demonstration. For the feasibility test, they implement three lab-based prototype FOVSs with different natural frequencies and measure each FOVS's frequency response according to the base vibration and sensitivity. The experimental results for three lab-based prototype FOVSs show the sensitivities of 163, 183, and 206 mV/g, the minimum detectable accelerations of 0.082, 0.086, and 0.082 mg, and the dynamic ranges of 18-45, 26-52, and 20-120 Hz, respectively. They also experimentally demonstrate its remote sensing and multipoint sensing characteristics. The proposed FOVS has the virtues of easy controllable sensitivity and dynamic range, simple structure, and remote sensing and multipoint sensing characteristics.</P>

Numerical study of complex modal characteristics in anguilliform mode of fish swimming

Zuo Cui,Hongzhou Jiang 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.10

In nature, anguilliform fish swim fast and efficiently by undulating their elongate body in a specific way, which is generally described as a travelling wave. In present work, the undulatory motions of anguilliform fish are analyzed by the method of complex orthogonal decomposition (COD), and these particular motions are decomposed into two parts: the travelling component and standing component. The relative ratio between the travelling and standing components is defined as the travelling index, and the biological data show that anguilliform fish prefer to the undulatory motions with high travelling index (0.74-0.90). To study this phenomenon, a two-dimensional numerical model of anguilliform fish is developed by our proposed LSIB numerical method, in which the shape of fish body is described by level-set (LS) function, and the interactive force is demonstrated by the immersed boundary (IB) method. The results show that the net force is decreased slightly with the travelling index, but the efficiency is increased with the travelling index until it reached to 0.8, which is consistent with the biological observations. Besides, the influences of the oscillating amplitude, tail-beat frequency and Strouhal number are also discussed. Overall, the results in present study can be used to explain why anguilliform fish would like to select the swimming gaits with high travelling index.

Zuo-zhou Zhao,An Duan,Ju Che,Jia-ru Qian,Wei-liang Jin 사단법인 한국계산역학회 2014 Computers and Concrete, An International Journal Vol.13 No.1

To evaluate the behavior of the advanced unbonded pre-stressed concrete containment vessel (UPCCV) for one typical China nuclear power plant under Japan’s March 11 earthquake, five nonlinear time history analysis and a nonlinear static analysis of a 1:10 scale UPCCV structure have been carried out with MSC.MARC finite element program. Comparisons between the analytical and experimental results demonstrated that the developed finite element model can predict the earthquake behavior of the UPCCV with fair accuracy. The responses of the 1:10 scale UPCCV subjected to the 11 March 2011 Japan earthquakes recorded at the MYG003 station with the peak ground acceleration (PGA) of 781 gal and at the MYG013 station with the PGA of 982 gal were predicted by the dynamic analysis. Finally, a static analysis was performed to seek the ultimate load carrying capacity for the 1:10 scale UPCCV.

c-Cbl-Mediated Neddylation Antagonizes Ubiquitination and Degradation of the TGF-β Type II Receptor

Zuo, W.,Huang, F.,Chiang, Y.,Li, M.,Du, J.,Ding, Y.,Zhang, T.,Lee, H.,Jeong, L.,Chen, Y.,Deng, H.,Feng, X.H.,Luo, S.,Gao, C.,Chen, Y.G. Cell Press 2013 Molecular cell Vol.49 No.3

Transforming growth factor β (TGF-β) is a potent antiproliferative factor in multiple types of cells. Deregulation of TGF-β signaling is associated with the development of many cancers, including leukemia, though the molecular mechanisms are largely unclear. Here, we show that Casitas B-lineage lymphoma (c-Cbl), a known proto-oncogene encoding an ubiquitin E3 ligase, promotes TGF-β signaling by neddylating and stabilizing the type II receptor (TβRII). Knockout of c-Cbl decreases the TβRII protein level and desensitizes hematopoietic stem or progenitor cells to TGF-β stimulation, while c-Cbl overexpression stabilizes TβRII and sensitizes leukemia cells to TGF-β. c-Cbl conjugates neural precursor cell-expressed, developmentally downregulated 8 (NEDD8), a ubiquitin-like protein, to TβRII at Lys556 and Lys567. Neddylation of TβRII promotes its endocytosis to EEA1-positive early endosomes while preventing its endocytosis to caveolin-positive compartments, therefore inhibiting TβRII ubiquitination and degradation. We have also identified a neddylation-activity-defective c-Cbl mutation from leukemia patients, implying a link between aberrant TβRII neddylation and leukemia development.

副詞“就”、“才”再探討

Zuo Simin 중국어문연구회 2019 中國語文論叢 Vol.0 No.93

In the paper the main characteristics of adverbs ‘Jiu(就)’ and ‘Cai(才)’ are examined, the usages of ‘Jiu(就)’ and ‘Cai(才)’ have been distinguished as follows: the former of which include seven emphatic usages and four non-emphatic usages, and the latter of which include five emphatic usages and four non-emphatic usages. The emphatic usages of the two words have the characteristic which does not change the truth value of a sentence, but conveys some conventional implicatures or plays a role of the trigger for pragmatic inference to induce pragmatic implicatures. The non-emphatic usages of the two words can be divided into two different kinds: (1) If ‘Jiu(就)’ or ‘Cai(才)’ is cancelled from a sentence, it does not affect the grammatical legitimacy of it, but will cause some changes in the meaning of the sentence. (2) If ‘Jiu(就)’ or ‘Cai(才)’ is cancelled from a sentence, the sentence will be not natural, even become ungrammatical. The research in this paper proves that the meanings and the usages of ‘Jiu(就)’ and ‘Cai(才)’ are very different from the explanations of traditional dictionaries. These two words not only convey the conventional implicatures or act as a trigger for pragmatic inference to induce pragmatic implicatures with a high frequency, but also can be used in several different ways when they convey or induce different implicatures. On the one hand, these phenomena indicate that ‘Jiu(就)’ and ‘Cai(才)’ are often used for pragmatic purpose, on the other hand, they indicate that the complexity of meaning structure and the usage of the two words is beyond the previous understanding of academia.
