      • An Iterative Space Alternative Tiling Parallel Algorithm for 3D Finite Difference Stencil Computations

        Jing Shen,Jilin Zhang,Jian Wan,Li Zhou,Ming Jiang 보안공학연구지원센터 2014 International Journal of Database Theory and Appli Vol.7 No.6

        Stencils are finite-difference algorithms for solving large-scale and high-dimension partial differential equations. Due to the data dependences among the iterative statements in Stencils, traditional Stencil computations are be executed serially, rather than in parallel. It’s challenging to design an effective and scalable Stencil parallelized method. To address the issue of 3D data space computing, we present a serial execution model based on multi-layers symmetric Stencil method and time skewing techniques. Within this model, the iteration space is divided to multiple tiles based on time skewing, where the executive process is ordered by the sequence of tiles, and the nodes in each individual tile can be swept repeatedly to improve the data locality. In addition, we propose a novel 3D iterative space alternate tiling Stencil parallel method, which subdivides the iteration space along high dimension, and changes the execution sequence of tiles to reduce the data dependency and communication cost, where the partial order of tiles is still guaranteed. Experimental results demonstrate our proposed alternative tiling parallel method achieves better parallel efficiency and scalability compared with the domain-decomposition methods.

        중국 아버지의 자기분화, 가족기능, 유아 문제행동의 구조모형분석

        Wan Jing,김현수,이성희 한국가족관계학회 2022 한국가족관계학회지 Vol.27 No.2

        연구목적: 중국 아버지의 자기분화가 유아 문제행동에 미치는 영향을 파악하고, 그 관계에서 가족기능이 매개역할을 하는지를 검증하였다. 이를 통해 유아 문제행동에서 아버지의 지원방안을 제시하였다. 연구방법: 중국 서남지역 3∼6세 유아자녀를 둔 아버지를 대상으로 온라인 설문조사를 실시하여 총 882부를 최종분석하였다. 자료분석은 SPSS 25.0과 AMOS 25.0을 사용하여 확인적 요인분석, 구조방정식모형검증, 부트스트래핑 방법을 수행하였다. 연구결과: 중국 아버지의 자기분화는 유아 문제행동에 직접적으로 영향을 미치고, 가족기능이 아버지의 자기분화와 유아 문제행동의 관계에서 매개효과를 가지는 것으로 나타났다. 즉 아버지의 자기분화수준이 높을수록 유아 문제행동은 감소하며, 가족기능이 매개변인으로 작용하여 유아자녀의 문제행동이 감소되는 것으로 나타났다. 결론: 유아 자녀의 문제행동에는 아버지의 자기분화 수준이 영향을 미치고, 가족기능이 보호요인으로 작용하므로 유아 문제행동에 대한 지원개입을 세울 때 가족체계가 고려될 필요가 있음을 시사한다.

        Analysis of the Genome Sequence of Strain GiC-126 of Gloeostereum incarnatum with Genetic Linkage Map

        ( Wan-zhu Jiang ),( Fang-jie Yao ),( Ming Fang ),( Li-xin Lu ),( You-min Zhang ),( Peng Wang ),( Jing-jing Meng ),( Jia Lu ),( Xiao-xu Ma ),( Qi He ),( Kai-sheng Shao ),( Asif Ali Khan ),( Yun-hui Wei 한국균학회 2021 Mycobiology Vol.49 No.4

        Gloeostereum incarnatum has edible and medicinal value and was first cultivated and domesticated in China. We sequenced the G. incarnatum monokaryotic strain GiC-126 on an Illumina HiSeq X Ten system and obtained a 34.52-Mb genome assembly sequence that encoded 16,895 predicted genes. We combined the GiC-126 genome with the published genome of G. incarnatum strain CCMJ2665 to construct a genetic linkage map (GiC-126 genome) that had 10 linkage groups (LGs), and the 15 assembly sequences of CCMJ2665 were integrated into 8 LGs. We identified 1912 simple sequence repeat (SSR) loci and detected 700 genes containing 768 SSRs in the genome; 65 and 100 of them were annotated with gene ontology (GO) terms and KEGG pathways, respectively. Carbohydrate-active enzymes (CAZymes) were identified in 20 fungal genomes and annotated; among them, 144 CAZymes were annotated in the GiC-126 genome. The A mating-type locus (MAT-A) of G. incarnatum was located on scaffold885 at 38.9 cM of LG1 and was flanked by two homeodomain (HD1) genes, mip and beta-fg. Fourteen segregation distortion markers were detected in the genetic linkage map, all of which were skewed toward the parent GiC-126. They formed three segregation distortion regions (SDR1-SDR3), and 22 predictive genes were found in scaffold1920 where three segregation distortion markers were located in SDR1. In this study, we corrected and updated the genomic information of G. incarnatum. Our results will provide a theoretical basis for fine gene mapping, functional gene cloning, and genetic breeding the follow-up of G. incarnatum.

        Genetic linkage map construction and quantitative trait loci mapping of agronomic traits in Gloeostereum incarnatum

        Jiang Wan-Zhu,Yao Fang-Jie,Lu Li-Xin,Fang Ming,Wang Peng,Zhang You-Min,Meng Jing-Jing,Lu Jia,Ma Xiao-Xu,He Qi,Shao Kai-Sheng 한국미생물학회 2021 The journal of microbiology Vol.59 No.1

        Gloeostereum incarnatum is an edible medicinal mushroom widely grown in China. Using the whole genome of G. incarnatum, simple sequence repeat (SSR) markers were developed and synthetic primers were designed to construct its first genetic linkage map. The 1,048.6 cm map is composed of 10 linkage groups and contains 183 SSR markers. In total, 112 genome assembly sequences were anchored, representing 16.43 Mb and covering 46.41% of the genome. Selfing populations were used for quantitative trait loci (QTL) targeting, and the composite interval mapping method was used to co-localize the mycelium growth rate (potato dextrose agar and sawdust), growth period, yield and fruiting body length, and width and thickness. The 14 QTLs of agronomic traits had LOD values of 3.20–6.51 and contribution rates of 2.22– 13.18%. No linkage relationship was found between the mycelium growth rate and the growth period, but a linkage relationship was observed among the length, width and thickness of the fruiting bodies. Using NCBI’s BLAST alignment, the genomic sequences corresponding to the QTL regions were compared, and a TPR-like protein candidate gene was selected. Using whole-genome data, 138 candidate genes were found in four sequence fragments of two SSR markers located in the same scaffold. The genetic map and QTLs established in this study will aid in developing selective markers for agronomic traits and identifying corresponding genes, thereby providing a scientific basis for the further gene mapping of quantitative traits and the marker-assisted selection of functional genes in G. incarnatum breeding programs.

      • Risk Factors of Hepatocellular Carcinoma - Current Status and Perspectives

        Gao, Jing,Xie, Li,Yang, Wan-Shui,Zhang, Wei,Gao, Shan,Wang, Jing,Xiang, Yong-Bing Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.3

        Hepatocellular carcinoma is a common disorder worldwide which ranks 5th and 7th most common cancer among men and women. In recent years, different incidence trends have been observed in various regions, but the reasons are not completely understood. However, due to the great public efforts in HCC prevention and alternation of lifestyle, the roles of some well documented risk factors played in hepatocarcinogenesis might have changed. This paper summarizes both the environmental and host related risk factors of hepatocellular carcinoma including well established risk factors such as hepatitis virus infection, aflatoxin and alcohol, as well as possible risk factors such as coffee drinking and other dietary agents.

        면세점 선택속성의 중요도-만족도(IPA)가 고객충성도에 미치는 영향 -방한 중국인 관광객을 중심으로-

        유찡찡 ( Jing Jing You ),한기완 ( Ki Wan Han ) 한국관광산업학회 2013 Tourism Research Vol.38 No.2

        Duty-free shopping is not only critical to tourist shopping, but also a sizable part in oversea tourism. From records of the Korea National Tourism Organization, Chinese tourists are increasing, and accordingly it estimates that the trend would accelerate in the future. To unleash the shopping passion of the expected Chinese tourists in Korea duty-free shops, it is necessary to study the duty-free shopping pattern of Chinese tourists to Korea. The following research is conducted for above reasons. Conclusions as below: First, in terms of optional attributes of duty-free shops, customers` importance scores higher than satisfaction, meaning the high expectation on duty-free shops. Thus to attract more Chinese tourists, the managers ought to understand their needs and enhance satisfaction. Second, though little correlation between importance and loyalty of optional attributes from Chinese tourists in Korea, there is strong mutual influence of satisfaction and loyalty of optional attributes. Therefore, improvement of satisfaction would lead improvement of loyalty. Third, from IPA analysis, it is obvious that Chinese tourists have high importance yet low satisfaction, and the other part which deserves centralized management is in-store activities. Managers of duty-free shops would realize that, among in-store activities, price is critical for tourists` selection, so that relevant policies on pricing should be the focus.

      • 中国互联网视听节目内容的监管政策浅析 : 以海外视听节目的监管政策为中心

        강완정(Jiang wan jing) 한국전자출판학회 2018 전자출판연구 Vol.- No.11

        In recent years, China s Internet has developed new patterns, and the new model has been emerging, and the Internet has been growing fast with video, and more and more is being broadcast live, short, video, Internet, and web series, and it s popular with the public. However, because the development time of Internet audio-visual programs is relatively short, the management and regulations of the industry have not yet established a sound system, and the related problems have come upon and affected the continuous healthy development of the whole industry. The surveillance of the Internet is one of the key parts of Internet monitoring, Internet culture management and information security, and it has been the focus of the government. Based on this, this study takes the overseas audio-visual programs broadcast on Internet platforms issued by the government after the reign of Xi jinping as the research object, sorts out the thoughts and specific countermeasures of the government on the online overseas audio-visual program communication supervision in recent years, and analyzes the impact of the government s strengthened control on the Chinese Internet audio-visual program market, especially the change in the number and mode of overseas audio-visual programs broadcast on the entire Internet content industry. 近年来中国的互联网新业态, 新模式层出不穷, 互联网视听节目借助视频网站发展迅猛, 直播、短视频、网综、网剧等网生内容越来越多, 深受广大人民群众的喜爱。但因为互联网视听节目发展时间较短, 行业的管理和规范还未形成一个健全的体制, 相关问题接踵而至, 影响了整个行业的持续健康发展。互联网视听节目的监管作为互联网监管 、互联网文化管理和信息安全的重要组成部分之一, 一直是政府重点关注的领域。2018年9月20日, 中国国家新闻出版广电总局发布了新的《境外人员参加广播电视节目制作管理规定(征求意见稿)》。意见稿中扩大了禁播境外视听节目范围, 并加强了对网络平台的境外视听节目总量加以限制。通过对比2004年发布的《境外电视节目引进、播出管理规定》可知, 意见稿将监管范围扩大为所有境外视听节目, 包括境外电影、动画片、纪录片、教育、科技、文化、综艺、体育等。 习近平主席执政后, 中共中央国务院高度重视三网融合推进工作, 将其纳入国家发展战略, 而网络视听节目传播则是三网融合核心议题的重要组成部分之一, 因此备受关注。政府相关部门数次出台相关政策, 持续加强监管力度。基于此, 本研究以习近平执政后, 政府出台对在互联网平台播出的海外视听节目监管政策为研究对象, 整理近年来政府对线上海外视听说节目传播监管的思路和具体对策, 同时分析随政府管控力度的加强以来, 对中国互联网视听节目市场, 特别是海外视听节目播放数量和方式的改变对整个互联网内容行业及造成的影响。

        Xia Lin,Jing-yan Gu,Wan-jun Guo,Ya-jing Meng,Hui-yao Wang,Xiao-jing Li,Wei Deng,Lian-sheng Zhao,Xiao-hong Ma,Ming-li Li,Ting Chen,S,K,Cheng,Tao Li 대한신경정신의학회 2021 PSYCHIATRY INVESTIGATION Vol.18 No.7

        Objective The current study aims to explore precipitating and social risk factors for internet addiction (IA) in university undergraduate students, and to provide evidence for interventions and the early prevention of IA in different genders. Methods Four thousand eight hundred and fifty-eight college sophomores completed an online survey on their internet use-related behaviours and social risk factors. Results We found that more male (8.3%) than female students (5.4%) had moderate and severe IA. The main online activity in the moderate and severe IA groups was online gaming in males and online streaming in females. Roommates engaging in similar internetbased entertainment was a risk factor of IA only for males, while not being in a romantic relationship was a risk factor of IA for females only. Infatuation with the internet before college and adjustment problems for college life were shared risk factors for both genders in the mild and moderate IA groups. Conclusion IA was a common phenomenon in college students with shared and unique precipitating and social risk factors in males and females. The gender-sensitive risk factors for IA warranted earlier and individualized intervention and prevention strategies for IA in this population.
