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.

A Novel Recursive Algorithm for Efficient ZF-OSIC Detection in a V-BLAST System

( Zuo-liang Yin ),( Xing-peng Mao ),( Qin-yu Zhang ),( Nai-tong Zhang ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.12

To reduce the implementation complexity of the Vertical Bell Labs layered space-time (V-BLAST) systems with respect to the zero-forcing (ZF) criterion, a computationally efficient recursive algorithm is proposed. A fast implementation of the proposed algorithm is developed and its complexity is analyzed in detail. The proposed algorithm matches the ZF-OSIC detection well, and its three significant advantages can be demonstrated by analyses and simulations. Firstly, its speedups over the conventional ZF-OSIC with norm-based ordering, the original fast recursive algorithm (FRA) and the fastest known algorithm (FKA) in the number of flops are 1.58, 2.33 and 1.22, respectively. Secondly, a much simpler implementation than FRA and FKA can be expected. Finally, the storage requirements are lower than those of FRA and FKA. These advantages make the proposed algorithm more efficient and practical.

A data fusion method for bridge displacement reconstruction based on LSTM networks

Zuo-Cai Wang,Da-You Duan,Xiao-Tong Sun,Yu Xin 국제구조공학회 2022 Smart Structures and Systems, An International Jou Vol.29 No.4

Bridge displacement contains vital information for bridge condition and performance. Due to the limits of direct displacement measurement methods, the indirect displacement reconstruction methods based on the strain or acceleration data are also developed in engineering applications. There are still some deficiencies of the displacement reconstruction methods based on strain or acceleration in practice. This paper proposed a novel method based on long short-term memory (LSTM) networks to reconstruct the bridge dynamic displacements with the strain and acceleration data source. The LSTM networks with three hidden layers are utilized to map the relationships between the measured responses and the bridge displacement. To achieve the data fusion, the input strain and acceleration data need to be preprocessed by normalization and then the corresponding dynamic displacement responses can be reconstructed by the LSTM networks. In the numerical simulation, the errors of the displacement reconstruction are below 9% for different load cases, and the proposed method is robust when the input strain and acceleration data contains additive noise. The hyper-parameter effect is analyzed and the displacement reconstruction accuracies of different machine learning methods are compared. For experimental verification, the errors are below 6% for the simply supported beam and continuous beam cases. Both the numerical and experimental results indicate that the proposed data fusion method can accurately reconstruct the displacement.

从三个方面看意义的规约化

Zuo Simin 한중인문학회 2020 한중인문학연구 Vol.68 No.-

From the angles of process and result, the conventionalization of meaning can be summed up as the formation of signification and re-formation of signification of various kinds of meaning expression at different levels. The conventionalization of meaning not only involves the solidification of the relationship between the signifier and the signified of a sign, but also includes at least the following three aspects: 1. The degree of stability of conventionalization, which is actually a matter of the degree and characteristics of solidification of a sign. 2. The expanded range of conventionalization, which is actually a matter of the capability and characteristics of a sign to increase its variety of meanings that can be expressed at the same level. 3. The representative rank of conventionalization, which is actually a matter of the capability and characteristics of a sign combination to reform its signification at the higher level. Through the discrimination and analysis of some examples, the related phenomena are discussed in the paper from above three aspects, and then some viewpoints are put forward on the basis. 과정과 결과라는 두 가지 측면에서 보았을 때, 의미 관습화는 다양한 종류, 다양한 단계상에서의 의미 표현 단위가 부호화 또는 재부호화 되는 것으로 귀결될 수 있다. 의미 관습화는부호에서 기표와 기의 간의 관계가 고착화되었는가 여부와 관련될 뿐만 아니라, 적어도 다음과 같은 세 가지 측면에서의 문제를 포함하고 있다. 1. 의미 관습화의 안정화 정도. 이는 실질적으로는 부호의 고착화 정도와 그 특징에 관한 문제이다. 2. 의미 관습화의 확장 범위. 이는실질적으로는 하나의 부호가 하나의 단계상에서 의미 표현 종류를 증강하는 능력과 그 특징에 관한 문제이다. 3. 의미 관습화의 표현 등급. 이는 실질적으로는 부호의 조합체가 더 높은단계에서 재부호화되는 능력과 그 특징에 관한 문제이다. 본고에서는 예시에 대한 분석을 통해 이 세 가지 측면의 현상을 보이고, 이를 기반으로 논의를 진행하였다.

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.

Transcatheter Arterial Chemoembolization Combined with Interferon-α is Safe and Effective for Patients with Hepatocellular Carcinoma after Curative Resection

Zuo, Chaohui,Xia, Man,Liu, Jingshi,Qiu, Xiaoxin,Lei, Xiong,Xu, Ruocai,Liu, Hanchun,Li, Jianliang,Li, Yongguo,Li, Qinglong,Xiao, Hua,Hong, Yuan,Wang, Xiaohong,Zhu, Haizhen,Wu, Qunfeng,Burns, Michael,Li Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.1

Objectives: Intrahepatic recurrence is the major cause of death among patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after curative surgical resection. Several approaches have been reported to decrease the recurrence rate. The objective of our study was to compare the clinical effects of transcatheter arterial chemoembolization (TACE) combined with interferon-alpha (IFN-${\alpha}$) therapy on recurrence after hepatic resection in patients with HBV-related HCC with that of TACE chemotherapy alone. Methods: We retrospectively analyzed the data from 228 patients who were diagnosed with HBV-related HCC and underwent curative resection between January 2001 to December 2008. The patients were divided into TACE (n = 126) and TACE-IFN-${\alpha}$ (n = 102) groups for postoperative chemotherapy. The TACE regimen consisted of 5-fluorouracil (5-FU), cisplatin (DDP), and the emulsion mixed with mitomycin C (MMC) and lipiodol. The recurrence rates, disease-free survival (DFS), overall survival (OS), and risk of recurrence were evaluated. Results: The clinicopathological parameters and adverse effects were similar between the 2 groups (P > 0.05). The median OS for the TACE-IFN-${\alpha}$ group (36.3 months) was significantly longer than that of the TACE group (24.5 months, P < 0.05). The 3-and 5-year OS for the TACE-IFN-${\alpha}$ group were significantly longer than those of the TACE group (P < 0.05) and the recurrence rate was significantly lower (P < 0.05). The TACE and IFN-${\alpha}$ combination therapy, active hepatitis HBV infection, the number of tumor nodules, microvascular invasion, liver cirrhosis, and the BCLC stage were independent predictors of OS and DFS. Conclusions: The use of the TACE and IFN-${\alpha}$ combination chemotherapy after curative hepatic resection safely and effectively improves OS and decreases recurrence in patients with HBV-related HCC who are at high risk. Our findings can serve as a guide for the selection of postoperative adjuvant chemotherapy for patients with HBV-related HCC who are at high risk of recurrence.
