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.
ON THE LARGE DEVIATION FOR THE GCF<sub>𝝐</sub> EXPANSION WHEN THE PARAMETER 𝝐 ∈ [-1, 1]
Zhong, Ting Korean Mathematical Society 2017 대한수학회지 Vol.54 No.3
The $GCF_{\epsilon}$ expansion is a new class of continued fractions induced by the transformation $T_{\epsilon}:(0, 1]{\rightarrow}(0, 1]$: $T_{\epsilon}(x)={\frac{-1+(k+1)x}{1+k-k{\epsilon}x}}$ for $x{\in}(1/(k+1),1/k]$. Under the algorithm $T_{\epsilon}$, every $x{\in}(0,1]$ corresponds to an increasing digits sequences $\{k_n,n{\geq}1\}$. Their basic properties, including the ergodic properties, law of large number and central limit theorem have been discussed in [4], [5] and [7]. In this paper, we study the large deviation for the $GCF_{\epsilon}$ expansion and show that: $\{{\frac{1}{n}}{\log}k_n,n{\geq}1\}$ satisfies the different large deviation principles when the parameter ${\epsilon}$ changes in [-1, 1], which generalizes a result of L. J. Zhu [9] who considered a case when ${\epsilon}(k){\equiv}0$ (i.e., Engel series).

The GCF$_\epsilon$ expansion is a new class of continued fractions induced by the transformation $T_{\epsilon}:(0,1]\to (0,1]$: $$ T_{\epsilon}(x)=\frac{-1+(k+1)x}{1+k-k\epsilon x} \ {\text{for}}\ x\in \big(1/(k+1), 1/k\big]. $$ \noindent Under the algorithm $T_{\epsilon}$, every $x\in (0,1]$ corresponds to an increasing digits sequences $\{k_n,{n\ge1}\}$. Their basic properties, including the ergodic properties, law of large number and central limit theorem have been discussed in \cite{Sc}, \cite{SZ} and \cite{Zh}. In this paper, we study the large deviation for the GCF$_\epsilon$ expansion and show that: $\big\{\frac{1}{n}\log k_n, n\ge1\big\}$ satisfies the different large deviation principles when the parameter $\epsilon$ changes in $[-1,1]$, which generalizes a result of L.~J.~Zhu \cite{Zhu} who considered a case when $\epsilon(k) \equiv 0$ (i.e., Engel series).

For generalized continued fraction (GCF) with parameter ${\epsilon}(k)$, we consider the size of the set whose partial quotients increase rapidly, namely the set $$E_{\epsilon}({\alpha}):=\{x{\in}(0,1]:k_{n+1}(x){\geq}k_n(x)^{\alpha}\;for\;all\;n{\geq}1\}$$, where ${\alpha}$ > 1. We in [6] have obtained the Hausdorff dimension of $E_{\epsilon}({\alpha})$ when ${\epsilon}(k)$ is constant or ${\epsilon}(k){\sim}k^{\beta}$ for any ${\beta}{\geq}1$. As its supplement, now we show that: $$dim_H\;E_{\epsilon}({\alpha})=\{\frac{1}{\alpha},\;when\;-k^{\delta}{\leq}{\epsilon}(k){\leq}k\;with\;0{\leq}{\delta}<1;\\\;\frac{1}{{\alpha}+1},\;when\;-k-{\rho}<{\epsilon}(k){\leq}-k\;with\;0<{\rho}<1;\\\;\frac{1}{{\alpha}+2},\;when\;{\epsilon}(k)=-k-1+\frac{1}{k}$$. So the bigger the parameter function ${\epsilon}(k_n)$ is, the larger the size of $E_{\epsilon}({\alpha})$ becomes.
HOW THE PARAMETER ε INFLUENCE THE GROWTH RATES OF THE PARTIAL QUOTIENTS IN GCFε EXPANSIONS
Ting Zhong,Luming Shen 대한수학회 2015 대한수학회지 Vol.52 No.3
For generalized continued fraction (GCF) with parameter ε(k), we consider the size of the set whose partial quotients increase rapidly, namely the set Eε(α) := {x ∈ 2 (0, 1] : kn+1(x) ≥ kn(x)α for all n ≥ 1}, where α > 1. We in [6] have obtained the Hausdorff dimension of Eε(α) when ε(k) is constant or ε(k) ~ kβ for any β ≥ 1. As its supplement, now we show that: dimH Eε(α) = {[수식] So the bigger the parameter function ε(kn) is, the larger the size of Eε(α) becomes.
A Study on Chinese Special Regulations Concerning the Maritime Claims
Fu, Ting-Zhong,Qiu, Jin Korean Institute of Navigation and Port Research 1997 한국항해학회지 Vol.21 No.3
Under Chinese law system, the maritime law is a special branch of the civil law. For this reason, the maritime litigation shall be governed correspondently by the civil prodecure law. However, since the maritime litigation has its own special prodecure which is different from that of general procedure, there must be some special regulations to be a supplement to the civil procedure law. In this paper, a study is made on such regulations which are "The Regulations Relating to the arrest of Ships Before Litigation" and "The Regulations Concerning the Auction of Ships Which Have Been Arrested by Maritime Court for Clearing off the Debts" The aim of this paper is to describe the basic principles established in the regulations mentioned above in order to make the people who are unfamiliar with Chinese maritime legislation to be understood about Chinese special procedure adopted in maritime litigation.maritime litigation.

Vascular endothelial growth factor (VEGF) is a potent regulator of angiogenesis and thereby involved in the development and progression of solid tumours. Associations between three VEGF gene polymorphisms (-634 G/C, +936 C/T, and +1612 G/A) and breast cancer risk have been extensively studied, but the currently available results are inconclusive. Our aim was to investigate associations between three VEGF gene polymorphisms and breast cancer risk in Chinese Han patients. We performed a hospital-based case-control study including 680 female incident breast cancer patients and 680 female age-matched healthy control subjects. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) analysis was performed to detect the three VEGF gene polymorphisms. We observed that women carriers of +936 TT genotypes [odds ratio (OR) =0.46, 95% confidence interval (CI) = 0.28, 0.76; P=0.002] or 936 T-allele (OR=0.81, 95% CI= 0.68, 0.98; P=0.03) had a protective effect concerning the disease. Our study suggested that the +1612G/A polymorphism was unlikely to be associated with breast cancer risk. The -634CC genotype was significantly associated with high tumor aggressiveness [large tumor size (OR=2.63, 95% CI=1.15, 6.02; P=0.02) and high histologic grade (OR=1.47, 95% CI= 1.06, 2.03; P=0.02)]. The genotypes were not related with other tumor characteristics such as regional or distant metastasis, stage at diagnosis, or estrogen or progesterone receptor status. Our study revealed that the VEGF -634 G/C and +936 C/T gene polymorphisms may be associated with breast cancer in Chinese Han patients.

Tumor formation and growth is dictated by a very small number of tumor cells, called cancer stem cells, which are capable of self-renewal. The genesis of cancer stem cells and their resistance to conventional chemotherapy and radiotherapy via mechanisms such as multidrug resistance, quiescence, enhanced DNA repair abilities and anti-apoptotic mechanisms, make it imperative to develop methods to identify and use these cells as diagnostic or therapeutic targets. Aldehyde dehydrogenase 1 (ALDH1) is used as a cancer stem cell marker. In this study, we evaluated ALDH1 expression in CaSki, HeLa and SiHa cervical cancer cells using the Aldefluor method to isolate ALDH1-positive cells. We showed that higher ALDH1 expression correlated with significantly higher rates of cell proliferation, microsphere formation and migration. We also could demonstrate that SiHa-ALDH1-positive cells were significantly more tumorigenic compared to SiHa-ALDH1-negative cells. Similarly, SiHa cells overexpressing ALDH1 were significantly more tumorigenic and showed higher rates of cell proliferation and migration compared to SiHa cells where ALDH1 expression was knocked down using a lentivirus vector. Our data suggested that ALDH1 is a marker of cervical cancer stem cells and expand our understanding of its functional role.
