본 연구는 녹색물류활동의 순물류활동과 역물류활동이 물류비절감과 배송품질에 긍정적 영향을 미치는지 확인하고, 그 관계에서 IT역량과 SCM통합노력이 긍정적 조절 효과를 갖는지 검토하기 위하여, 162개의 국내 제조 기업을 대상으로 설문조사를 실시하고 PLS를 활용하여 실증분석 하였다. 분석 결과, 녹색 순물류활동과 역물류활동은 모두 물류비절감에 유의한 영향을 미치고, 녹색 순물류활동은 배송품질에 유의한 영향을 미치는 것으로 검증되었다. 연구의 두 번째 단계에서, IT역량이 높아질수록 녹색 역물류활동이 물류비절감에 미치는 영향이 커질 것이라는 가설은 채택되었지만, SCM통합노력 정도가 높을수록 녹색 순물류 및 역물류활동이 물류비 절감과 배송품질에 미치는 영향이 클 것이라는 가설은 모두 기각되었다. 이러한 결과에서 장기적으로는 IT역량이 높아짐에 따라 순물류활동에서의 배송품질이 높아지고 이에 따른 고객만족도가 높아지면 수익률도 높아져 궁극적으로 물류비에 긍정적인 영향을 주게 될 수 있게 될 것이라는 시사점을 얻을 수 있었다. SCM통합이 기업의 성과에 영향을 미치는 정도가 대기업과 중소기업에 따라 다르기 때문에 중소기업의 경우 공급사슬 전체의 통합을 위한 노력에 비하여 그 성과가 크지 않다는 점과 공급사슬 전체의 통합보다는 내부통합이나 고객과의 관계 개선을 통하여 효율성을 높이는 것이 주요한 전략일 수 있다는 점을 시사한다. The purpose of this study was to examine if information technology (IT) capability and supply chain integration efforts moderate the effects of green logistics practices on firm``s logistics performance including logistics costs reduction and delivery quality. Based on the past literature, we explored the relationships between the factors representing firm``s forward and reverse green logistics practices, and developed researchable hypotheses. A survey was given to the Korean manufacturing companies and the collected survey data were analyzed using SmartPLS2.0 to test the hypotheses. This study implied the definite needs to enhance IT capability and supply chain integration efforts to improve logistics performance through green logistics practices. The findings from the analyses were as follows: First, the forward green logistics practices positively affect logistics costs reduction and delivery quality. The green reverse logistics practices have a positiveimpact on logistics cost reduction but a negative impact on delivery quality. Second, firm``s IT capability moderated the effect of green forward logistics practices on delivery quality and the effect of green reverse logistics practices on logistics cost reduction. Supply chain integration efforts moderated the effect of green forward logistics practices on delivery quality, did negatively moderate the effect of green reverse logistics practices on logistics cost reduction.

Ying Qin,Gan-Ping Shu,Er-Feng Du,Rui-Hua Lu 국제구조공학회 2018 Steel and Composite Structures, An International J Vol.29 No.3

In this research, the explicit closed-form local buckling solution of steel plates in contact with concrete, with both loaded and unloaded edges elastically restrained against rotation and subjected to eccentric compression is presented. The Rayleigh-Rize approach is applied to establish the eigenvalue problem for the local buckling performance. Buckling shape which combines trigonometric and biquadratic functions is introduced according to that used by Qin <i>et al</i>. (2017) on steel plate buckling under uniform compression. Explicit solutions for predicting the local buckling stress of steel plate are obtained in terms of the rotational stiffness. Based on different boundary conditions, simply yet explicit local buckling solutions are discussed in details. The proposed formulas are validated against previous research and finite element results. The influences of the loading stress gradient parameter, the aspect ratio, and the rotational stiffness on the local buckling stress resultants of steel plates with different boundary conditions were evaluated. This work can be considered as an alternative to apply a different buckling shape function to study the buckling problem of steel plate under eccentric compression comparing to the work by Qin <i>et al</i>. (2018), and the results are found to be in consistent with those in Qin <i>et al</i>. (2018).

세시풍속을 통해서 본 중국 12띠의 양상과 문화화 방식

경서근 ( Rui Qin Geng ) 남도민속학회 2010 남도민속연구 Vol.20 No.-

중국에서 12띠는 유구한 문화적 상징으로 오래전부터 전승되어 왔으며 문화화 방 식도 매우 다양하게 활용되었다. 그래서 12띠에 대한 연구는 문화의 상징체계를 해석 하는 중요한 통로가 될 수 있다 특히 세시풍속이라는 문호}적 행위 속에서 12띠의 문 화화 방식을 연구하는 것은 중국의 생활양식, 민족성, 가치묘털 이해하는 데 의미 있 는작업이다. 세시는 기본적으로 생성과 성장과 결실과 소멸이라고 하는 순환적 시간관에 기초하 고 있다 따라서 이 논문에서 春夏秋추 사계절의 개념을 도입하여 연구의 기본 툴로 삼았다. 그리고 12띠 동물의 고유 의미가 세시라고 하는 시간성 위에 놓일 때 어떻게 그 의미가 재생산되는가를 고찰했다 또한 사계절의 띠에 관련된 여러 가지 세시풍속 을 통해서 12띠 동물의 존재o~o상과 문화적 방식을 정리했다. 문화화 방식은 대체적으 로 의례화 방식, 축제 · 놀이화 방식, 음성유사화 방식, 문양화 전승 네 가지가 있다. 그런데 필자의 역량부족으로 두 가지 아쉬운 점이 있으며, 이는 훗날의 연구 과제로 남기고자 한다. 첫째, 중국 12띠와 한국 12띠를 비교해 볼 수 없었다는 점이다. 12띠 는 동아시아가 공유하는 문화적 상징체계이묘로 두 나라의 세시풍속에 나타나는 12띠 의 양상과 문화화 방식이 비교될 때 12띠의 의미가 더욱 확실히 드러나고 이해가 쉬 울 것은 자명한 일이다. 둘째는 12띠를 중국의 한정된 지역으로 제한하여 연구하는 것이다. 중국은 영토가 넓고 인구가 많기 때문에 지역마다 민족마다 생활방식, 세시풍 속은 서로 다르다. 따라서 세시풍속이 풍부한 소수민족을 대상으로 12띠의 전승과 문목포대학교 국어국문학과 박사과정8 남도민속연구 저120집 화화방식을 갚이 들여다보는 작업이 필요하다고 생각한다 The Chinese Zodiac has been passed down as a symbol of richly historied cultural since a long time ago. Their enculturation ways were used in great variety of ways. So the study of the Chinese Zodiac can become an important way to explain cultural symbol-system. Especially, the study on cultural way of the Chinese Zodiac is a task of great significance to understand lifestyle, nation``s history and values of China in seasonal customs. Seasonal customs are based on circular time called the creation, development and destruction. So introduce the concepts of 4 seasons as a framework of this study. And when unique meaning of the Chinese Zodiac is combined with timeliness called seasonal customs, it is considered that how to reproduce the meaning. And existent expression and culture ways of the Chinese zodiac are sorted out through many seasonal customs involved with the Chinese Zodiac. The culture ways include formality way, festival-amusement way, voice similarity``s way and patterns in principle. However, there are two kinds of frustration because of a lack of capability. And many subjects are left for future studies. First, the Chinese zodiac can``t be compare with the twelve animals of korea. When compared to appearances and culture ways of the Chinese zodiac which appear on seasonal customs of two Mokpo National University countries, it``s certain that the meaning of Chinese Zodiac certainly becomes more easy to understand because chinese zodiac sign is a symbol of culture which belongs to East Asian region. Secondly, this study is limited in China. Because of a great expanse of land a large number of people in China, there is its own lifestyle and seasonal customs in various nationalities. So it``s necessary to look into culture ways of the Chinese Zodiac targeted ethnic minorities rich in seasonal customs.

Genotype Distribution of Human Papillomavirus in Women with Abnormal Cervical Cytology in an Esophageal Carcinoma High Incidence Area of China

Mai, Rui-Qin,Huang, Bo,Shen, Ling,Zhang, Guo-Hong,Hong, Liang-Li,Cai, Ying-Mu Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.12

Infection with human papillomavirus (HPV) could affect genesis of both cervical and esophageal cancers. The type-specific distribution of HPV in cervical cytology abnormalities of women has remained unclear in Shantou, an esophageal cancer high-incidence area of China. Data from 22,617 women who were subjected to cervical HPV DNA testing with simultaneous cervical cytological examination during 2009-2013 were therefore here retrospectively evaluated in a hospital-based study. Overall, 16.2% (3,584/22,114)of women with normal cytology were HR-HPV positive, with HPV-52 (4.07%) as the most common type followed by -16 (3.63%), and -58 (2.46%). Prevalence of HR-HPV was 50.3% (253/503) in women with cervical cytological abnormalities, of which in ASC-H 71.4%, ASC-US 39.1%, HSIL 80.3% and LSIL 73.7%. HPV-58 (14.12%) was the most common type for all cervical cytological abnormalities, followed by HPV-16 (13.72%), and -52 (12.72%), while the more common HPV-16 type in ASC-H (42.9%) and HSIL (36.1%), HPV-52 and -58 were the most common types for ASC-US (10.3%) and LSIL (25%), respectively. Multiple HPV co-infections were identified in 33.2% (84/253) cytology abnormalities with positive HR-HPV, and the highest prevalence of HPV-58/16 combination in HSIL (28.6%, 6/21) was observed. Our data indicated a relative high prevalence of HPV-58 and -52 in women with cervical cytological abnormalities, which should be considered in the development of next-generation vaccines for Shantou.

Schedule Optimization for Ttethernet-based Time-triggered Automotive Systems

Zhao Rui,Qin Guihe,Yan Jie,Qin Jun 한국자동차공학회 2020 International journal of automotive technology Vol.21 No.6

TTEthernet is a new high availability network protocol for the automotive domain, providing support for the transmissions of time-critical periodic frames in a time-triggered (TT) traffic and event-triggered frames in a rate-constrained (RC) or best-effort (BE) traffic. The design of a system scheduling with communication over the TTEthernet is not an easy task because of protocol and timing constraints as well as the demand for high quality-of-service and extensibility. In this paper, we study the co-optimization problem of the tasks and signals scheduling for TTEthernet-based time-triggered automotive systems. We propose a Mixed-Integer Linear Programming (MILP) framework for optimizing the signal packing, signal scheduling and task scheduling, subject to all protocol, processor and timing constraints with respect to latency- or extensibility- related metrics. Extensive experiments are conducted to evaluate the effectiveness and efficiency of the proposed approach in a variety of scenarios.

Ge, Yi-Rui,Tian, Nong,Lu, Yan,Wu, Yong,Hu, Qin-Rui,Huang, Zheng-Ping Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.10

Background: Many observational studies have assessed the possible association between occupational cooking and uveal melanoma risk, but reported results are controversial. Our goal was to evaluate the association between occupational cooking and uveal melanoma risk by conducting a meta-analysis of observational studies. Methods: PubMed, EMBASE, and Web of Science were searched through June 2012 to identify all eligible studies. The pooled odds ratio (OR) with its 95% confidence interval (95%CI) was used to evaluate this association. Either a fixed- or a random-effects model were used to calculate pooled ORs. Results: Five case-control studies involving a total of 1,199 cases and 6,927 controls were included in the meta-analysis. Overall, occupational cooking was associated with an increased risk of uveal melanoma (OR: 1.81, 95%CI 1.33-2.46, P < 0.001). Subgroup analysis by gender suggested occupational cooking was associated with increased risk of uveal melanoma in both men (OR: 2.16, 95%CI 1.06-4.40, P = 0.034) and women (OR: 1.92, 95%CI 1.19-3.10, P = 0.008). Conclusion: This meta-analysis suggests that occupational cooking is associated with an increased risk of uveal melanoma in both men and women.

Study on Enhancing Lightning Protection Scheme of Catenary in Subway Viaduct Section

Rui-Fang Li,Kui Chen,Li-Sheng Chen,Xiao-Bin Cao,Guang-Ning Wu,Xue-Qin Zhang 대한전기학회 2017 Journal of Electrical Engineering & Technology Vol.12 No.2

Viaduct increases the height of subway catenary, namely magnifies lightning attraction scope that lead to higher possibility of suffering lightning stroke. Therefore, it is necessary to analyze performance of lightning striking to catenary of subway in viaduct section and propose an improving lightning protection scheme. In this paper, using ATP-EMTP simulation software to establish an associated model to evaluate lightning withstand level of catenary with existing lightning protection schemes including arrester and grounding point, an improving lightning protection scheme is proposed — every pillar ground earth and arresters are installed with some installing spacing between 200m to 400m based on lightning damage degree and reliability requirements — according to analyzing results: while lightning withstand level is lowest for lightning striking to the neutral pillar, lightning withstand level is greatest for lightning striking to the both-ends pillar that arrester and grounding point are both installed; grounding point could obviously improve lightning withstand level for lightning striking to ground wire while arrester could obviously improve the lightning withstand level for lightning striking to catenary; every pillar ground earth could enhance the lowest lightning withstanding level up to 2.5 times than of that pillar ground earth across every 200m.

Rui Ma,Zeyu Qin,Wencan Yang,Mo Li 대한전기학회 2016 Journal of Electrical Engineering & Technology Vol.11 No.6

A novel method is proposed to construct the voltage stability boundary of power system considering different Reactive Power Control Mode (RPCM) of Doubly-Fed Induction Generator (DFIG) Wind Power Plant (WPP). It can be used for reflecting the static stability status of grid operation with wind power penetration. The analytical derivation work of boundary search method can expound the mechanism and parameters relationship of different WPP RPCMs. In order to improve the load margin and find a practical method to assess the voltage security of power system, the approximate method of constructing voltage stability boundary and the critical points search algorithms under different RPCMs of DFIG WPP are explored, which can provide direct and effective reference data for operators.

Rui Li,Gang Wang,Zheng‑Yong Wen,Yuan‑Chao Zou,Chuan‑Jie Qin,Yu Luo,Jun Wang,Gui‑Hong Chen 한국유전학회 2019 Genes & Genomics Vol.41 No.2

The snakehead fish, Channa siamensis, belongs to the genus of Channa (perciformes: Channidae) and was first reported by Günther in 1861. Despite it has been described approximately for 15 decades, the genetic information is limited and the taxon status of this kind of fish is still unclear. The primary objective of this study is to get more genomic data and calculate the taxon location of this kind of fish. The next generation sequencing method was used to obtain the whole mitochondrial DNA information, and bioinformatic analysis was performed to investigate the evolutionary status and taxon location of C. siamensis. The circular mitochondrial DNA was 16,570 bp in length, and which showed typical piscine structure and arrangement. The overall nucleotide composition was 29.28% A, 24.72% T, 30.71% C, 15.29% G, with 54.1% AT, respectively. Phylogenetic analyses using concatenated amino acid and nucleotide sequences of the 13 protein-coding genes with two different methods (Maximum likelihood and Bayesian analysis) both highly supported C. siamensis belongs to the genus Channa and shows a close relationship with C. micropeltes. These data will provide more useful information for a better understanding of the mitochondrial genomic diversities and evolution in fish as well as novel genetic markers for studying population genetics and species identification.
