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.

As lipolytic enzymes, GDSL lipases play an important role in plant growth and development. In order to identify their functions and roles, the full-length cDNA of a GDSL lipase gene, designated BnLIP2, was isolated from Brassica napus L. BnLIP2 was 1,300 bp long, with 1,122 bp open reading frame (ORF) encoding 373 amino acid residues. Sequence analysis indicated that BnLIP2 belonged to GDSL family. Southern blot analysis indicated that BnLIP2 belonged to a small gene family in rapeseed genome. RT-PCR analysis revealed that BnLIP2 was a tissue-specific expressing gene during reproductive growth and strongly expressed during seed germination. BnLIP2 expression could not be detected until three days after germination, and it subsequently became stronger. The transcript of this gene was deficient in root of seedlings growing at different stages. When juvenile seedlings were treated by methyl jasmonate (MeJ), salicylic acid (SA) and naphthalene acetic acid (NAA), BnLIP2 expression could not be induced in root. Our study implicates that BnLIP2 probably plays an important role in rapeseed germination, morphogenesis, flowering, but independent of root growth and development.

Energy-efficient Low-delay TDMA Scheduling Algorithm for Industrial Wireless Mesh Networks

( Yun Zuo ),( Zhihao Ling ),( Luming Liu ) 한국인터넷정보학회 2012 KSII Transactions on Internet and Information Syst Vol.6 No.10

Time division multiple access (TDMA) is a widely used media access control (MAC) technique that can provide collision-free and reliable communications, save energy and bound the delay of packets. In TDMA, energy saving is usually achieved by switching the nodes` radio off when such nodes are not engaged. However, the frequent switching of the radio`s state not only wastes energy, but also increases end-to-end delay. To achieve high energy efficiency and low delay, as well as to further minimize the number of time slots, a multi-objective TDMA scheduling problem for industrial wireless mesh networks is presented. A hybrid algorithm that combines genetic algorithm (GA) and simulated annealing (SA) algorithm is then proposed to solve the TDMA scheduling problem effectively. A number of critical techniques are also adopted to reduce energy consumption and to shorten end-to-end delay further. Simulation results with different kinds of networks demonstrate that the proposed algorithm outperforms traditional scheduling algorithms in terms of addressing the problems of energy consumption and end-to-end delay, thus satisfying the demands of industrial wireless mesh networks.

( Yongdi Wang ),( Ling Chen ),( Junke Wang ),( Wang Zuo ) 한국융합과학회 2022 한국융합과학회 국제학술대회자료집 Vol.2022 No.0

What is happiness? It has been a problem that many philosophers have valued since ancient times, and it is also a very important topic for today in the new era. Happiness is an important comprehensive psychological index to measure the quality of personal life. In recent years, more and more college students have nowhere to vent their psychological pressures, such as difficulties, low self-esteem, shyness, academic pressure, and so on, so they choose to participate in sports dance. However, participating in dance sports can help college students adjust their life and learning atmosphere, as well as changes in their own image and inferiority. It has gradually become one of the favorite sports of Chinese college students. Therefore, it is necessary to verify the factors that influence the well-being of dance sports participants. The purpose of this study was to test the fit of the research model and to explore the relationship between enjoyment factors, satisfaction, flow experience and well-being among college dance participants in Hunan Province. To further analyze the relationship between enjoyment factors and well-being of dance participants in Hunan Province, and the mediating role of flow experience and satisfaction in the relationship. Methods This study is to investigate the relationship between Enjoyment-factors, Satisfaction, Flow-Experience, Happiness among Dance Sports Participants of College Student .In this study, 13 prefecture-level cities in Hunan Province were used as the survey area. The cluster random sampling method was used in this study. According to previous research, the General Well-Being Schadule (GWBS) was revised in 1977 by American psychologist Fazio. There are 69 items in the revised scale, 46 items are newly added, and appropriate speech adjustments are made to the remaining 23 items. According to the recommendations of Anderson and Gerbing (1988), data analysis is divided into two stages. In the first stage, confirmatory factor analysis (CFA) is used to test the reliability and validity of the scale. In the second stage, structural equation modeling (SEM) analysis is used to test the proposed hypotheses. Findings and Discussions There was a significant correlation between the enjoyment factors and satisfaction. There is a significant correlation between enjoyment factors and flow experience. The correlation between the enjoyment factors and happiness is not significant. There is a significant correlation between flow experience and satisfaction. The correlation between flow experience and happiness is significant. The correlation between satisfaction and happiness is significant. In addition, the enjoyment factors have an indirect effect on happiness through the intermediate variable of flow experience. In the structural equation model test results, the levels of enjoyment factors of dance sports participants can be used as predictors of satisfaction. The level of enjoyment factors of dance sports participants can be used as predictors of flow experience. The enjoyment factors are not the direct factors affecting happiness. The level of flow experience of dance sports participants can be used as a predictor of satisfaction. It shows that flow experience is an important factor affecting happiness, and it has positive significance for improving the happiness of dance sports participants. Satisfaction is an important factor affecting happiness, and it has positive significance for improving the happiness of dance sports participants. The enjoyment factors have an indirect effect on happiness through the intermediate variable of flow experience. Enjoyment factors need to improve well-being by increasing the mediating role of flow experience.

Low-delay Node-disjoint Multi-path Routing using Complementary Trees for Industrial Wireless Sensor Networks

( Luming Liu ),( Zhihao Ling ),( Yun Zuo ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.11

Complementary trees are two spanning trees rooted at the sink node satisfying that any source node`s two paths to the sink node on the two trees are node-disjoint. Complementary trees routing strategy is a special node-disjoint multi-path routing approach. Several complementary trees routing algorithms have been proposed, in which path discovery methods based on depth first search (DFS) or Dijkstra`s algorithm are used to find a path for augmentation in each round of path augmentation step. In this paper, a novel path discovery method based on multi-tree-growing (MTG) is presented for the first time to our knowledge. Based on this path discovery method, a complementary trees routing algorithm is developed with objectives of low average path length on both spanning trees and low complexity. Measures are employed in our complementary trees routing algorithm to add a path with nodes near to the sink node in each round of path augmentation step. The simulation results demonstrate that our complementary trees routing algorithm can achieve low average path length on both spanning trees with low running time, suitable for wireless sensor networks in industrial scenarios.

Development of a distributed high-speed data acquisition and monitoring system based on a special data packet format for HUST RF negative ion source

Li Dong,Yin Ling,Wang Sai,Zuo Chen,Chen Dezhi 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.10

A distributed high-speed data acquisition and monitoring system for the RF negative ion source at Huazhong University of Science and Technology (HUST) is developed, which consists of data acquisition, data forwarding and data processing. Firstly, the data acquisition modules sample physical signals at high speed and upload the sampling data with corresponding absolute-time labels over UDP, which builds the time correlation among different signals. And a special data packet format is proposed for the data upload, which is convenient for packing or parsing a fixed-length packet, especially when the span of the time labels in a packet crosses an absolute second. The data forwarding modules then receive the UDP messages and distribute their data packets to the real-time display module and the data storage modules by PUB/SUB-pattern message queue of ZeroMQ. As for the data storage, a scheme combining the file server and MySQL database is adopted to increase the storage rate and facilitate the data query. The test results show that the loss rate of the data packets is within the range of 0e5% and the storage rate is higher than 20 Mbps, both acceptable for the HUST RF negative ion source
