Han-Shu Zhou,Ying-Jun Zhang 한국초지조사료학회 2009 한국초지조사료학회 학술대회논문집 Vol.2009 No.08

The research was conducted at a degraded steppe in Saibei Adiministrative Region of ZhangJiakou in Hebei province. Four patches dominated by fringed sagebrush (Artemisia frigida), narrowleaf stellera (Stellera chamaejasme), shining speargrass (Achnatherum splendens), white swordflag (Iris lactea), respectively, were sampled. Phosphorus (P) was applied at four levels (0, 5, 10 and 15㎎ ㎏?¹ soil) in each patch. The mycorrhizal infection rate in Stellera chamaejasme species and Achnatherum splendens species was low, differed from other two patches of Artemisia frigid and Iris lactea.

중국 성인소비자의 소비성향과 제품가치평가가 패션 사치품 구매의도에 미치는 영향

Zhou han,홍은실 한국소비문화학회 2022 소비문화연구 Vol.25 No.4

한국의 최대 교역국인 중국은 최근 몇 년간 사치품 구매 빈도와 액수가 급증하여 세계 사치품 시장의 큰 비중을 차지하게 되었다. 이에 사치품을 구매해 본 경험이 있는 중국 성인소비자를 대상으로 하여 사치품 구매의도에 초점을 두어 그들의 사치소비 의도를 진단하고, 사치품 구매의도를 결정하는 영향요인으로 소비성향과 제품가치평가의 영향력을 검증하였다. 선행연구 척도를 사용하여 온라인 설문조사를 실시하여 총 405부를 분석자료로 사용하였다. 자료분석은 SPSS를 사용하여 Cronbach’ α계수, t검증, 일원분산분석과 던컨사후검증, 위계적 회귀분석을 실시하였다. 분석 결과, 사치품 구매 경험이 있는 중국 성인소비자는 사치품 구매에서 ‘자기만족’을 기준으로 삼는 소비성향이 상대적으로 가장 높았으며, 사치품의 가치평가에서 ‘심미성’을 가장 높게 평가하였다. 이들 변인은 다른 변인들을 통제했을 때 사치품의 구매의도에 가장 큰 영향을 미치는 변수로 밝혀졌다. 즉 최종적인 분석에서 사치품 구매의도에 가장 큰 영향을 미치는 변수는 자기만족 소비성향이었으며, 그 다음은 심미성과 고가성의 제품가치평가 변인이었다. 사치품 구매에서 자기만족을 기준으로 삼으며 사치품이 지니는 심미성과 고가성을 높이 평가하는 소비자일수록 추후 사치품 구매의사가 높기 때문에 이를 반영한 사치품 마케팅전략 수립이 요구된다. 또한 사치품 구매의도에서 소비성향과 제품가치평가의 역할과 기능이 확인되었다. 이러한 결과는 개인 소비자의 만족을 극대화하는 사치품 소비생활 지침에 대한 자료로 사용될 수 있으며, 중국과 한국 사치품 소비시장의 경제적 성장 및 확대를 가져오는 사치품 수요 증가 방안 모색에 활용될 수도 있을 것이다.

Han-Lu Gao,Xuan Wang,Hong-Ru Sun,Jun-De Zhou,Shang-Qun Lin,Yu-Hang Xing,Lin Zhu,Hai-Bo Zhou,Ya-Shuang Zhao,Qiang Chi,Yu-Peng Liu 거트앤리버 소화기연관학회협의회 2018 Gut and Liver Vol.12 No.2

Background/Aims: Methylation status plays a causal role in carcinogenesis in targeted tissues. However, the relationship between the DNA methylation status of multiple genes in blood leukocytes and colorectal cancer (CRC) susceptibility as well as interactions between dietary factors and CRC risks are unclear. Methods: We performed a case-control study with 466 CRC patients and 507 cancer-free controls to investigate the association among the methylation status of individual genes, multiple CpG site methylation (MCSM), multiple CpG site heterogeneous methylation and CRC susceptibility. Peripheral blood DNA methylation levels were detected by performing methylation-sensitive high-resolution melting. Results: Total heterogeneous methylation of CA10 and WT1 conferred a significantly higher risk of CRC (adjusted odds ratio [ORadjusted], 5.445; 95% confidence interval [CI], 3.075 to 9.643; ORadjusted, 1.831; 95% CI, 1.100 to 3.047; respectively). Subjects with high-level MCSM (MCSM-H) status demonstrated a higher risk of CRC (ORadjusted, 4.318; 95% CI, 1.529 to 12.197). Additionally, interactions between the high-level intake of fruit and CRH, WT1, and MCSM on CRC were statistically significant. Conclusions: The gene methylation status of blood leukocytes may be associated with CRC risk. MCSM-H of blood leukocytes was associated with CRC, especially in younger people. Some dietary factors may affect hypermethylation status and influence susceptibility to CRC.

Zhou, Hang,Li, Xiong,Zhang, Yuan,Jia, Yao,Hu, Ting,Yang, Ru,Huang, Ke-Cheng,Chen, Zhi-Lan,Wang, Shao-Shuai,Tang, Fang-Xu,Zhou, Jin,Chen, Yi-Le,Wu, Li,Han, Xiao-Bing,Lin, Zhong-Qiu,Lu, Xiao-Mei,Xing, H Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.9

Background: This study aimed to establish a nomogram by combining clinicopathologic factors with overall survival of stage IA-IIB cervical cancer patients after complete resection with pelvic lymphadenectomy. Materials and Methods: This nomogram was based on a retrospective study on 1,563 stage IA-IIB cervical cancer patients who underwent complete resection and lymphadenectomy from 2002 to 2008. The nomogram was constructed based on multivariate analysis using Cox proportional hazard regression. The accuracy and discriminative ability of the nomogram were measured by concordance index (C-index) and calibration curve. Results: Multivariate analysis identified lymph node metastasis (LNM), lymph-vascular space invasion (LVSI), stromal invasion, parametrial invasion, tumor diameter and histology as independent prognostic factors associated with cervical cancer survival. These factors were selected for construction of the nomogram. The C-index of the nomogram was 0.71 (95% CI, 0.65 to 0.77), and calibration of the nomogram showed good agreement between the 5-year predicted survival and the actual observation. Conclusions: We developed a nomogram predicting 5-year overall survival of surgically treated stage IA-IIB cervical cancer patients. More comprehensive information that is provided by this nomogram could provide further insight into personalized therapy selection.

Disc-type Underwater Glider Modeling and Analysis for Omnidirectional and Steering Motion Characteristics

Han Zhou,Tianlin Wang,Li Sun,Xiang Jin 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.1

A disc-type underwater glider (DTUG) has a highly symmetrical full-wing shape that allows it to moveomnidirectionally and have the same hydrodynamic characteristics in all directions in the horizontal plane. Thesecharacteristics make the viscous hydrodynamic coefficients measured by conventional methods unsuitable for simulating the omnidirectional and steering motions of the DTUG. To further reveal the omnidirectional and steeringmotion characteristics of the DTUG, this paper proposes a new theoretical method for calculating the DTUG motion control equations in the velocity frame rather than the body frame. Based on the structural characteristics ofthe DTUG, the motion control equations are derived and then solved using the fourth-order Runge-Kutta method. The omnidirectional and steering motions of the DTUG are simulated in the velocity frame and compared withthe results calculated in the body frame. The results show that the viscous hydrodynamic coefficients obtained byconventional methods are not suitable for analyzing the omnidirectional motion of the DTUG, and the method ofcalculating the motion control equations in the body frame has limitations in studying the steering motion. The newmethod proposed in this paper solves these limitations well and can more accurately reveal the motion characteristics of the DTUG without recalculating the hydrodynamic coefficients. The results also show that the DTUG canchange the heading angle more easily than a torpedo-type underwater glider (TTUG), and the steering radius ismuch smaller, which means that the DTUG has greater flexibility in a small body of water. The DTUG can remainstable when the control variables are within the control range and the new method is adopted.

Trends in Specific Immunotherapy for Allergic Rhinitis: A Survey of Chinese ENT Specialists

Han Zhou,Qi-Lei Tao,Jun-Min Wei,Geng Xu,Lei Cheng 대한천식알레르기학회 2014 Allergy, Asthma & Immunology Research Vol.6 No.4

Purpose: Specific immunotherapy (SIT) is a suitable but uncommon treatment option for allergic rhinitis (AR) in China. The current understandingand attitude of Chinese ENT (ear, nose, and throat) specialists in regards to SIT is unclear. This study investigates current trends in the awarenessand application status of SIT among Chinese ENT specialists. Methods: We performed a nationwide, cross-sectional survey with a specially designedquestionnaire given to 800 ENT specialists in China. A member of the trained research group conducted face-to-face interviews with eachrespondent. Results: Most of the respondents considered AR (96.0%) and allergic asthma (96.0%) the most suitable indications for SIT. Of all respondents,77.0% recommended the application of SIT as early as possible; in addition, SIT was considered ‘relatively controllable and safe’ bymost respondents (80.6%). The highest allergen-positive rate in AR was associated with house dust mite (47.7%) and obvious differences existedamong geographical regions. Conventional subcutaneous immunotherapy was the most highly recommended treatment option (96.2%). ‘The highcost of SIT’ (86.6%) and ‘lack of patient knowledge of SIT’ (85.2%) were probably the main reasons for the lower clinical use of SIT in China. Conclusions:Most cases showed that the opinions of Chinese ENT specialists appeared to be in agreement with recent SIT progress and internationalguidelines; however, many areas still need to enhance the standardization and use of SIT in China. Clinical guidelines for SIT require improvement;in addition, Chinese ENT specialists need continuing medical education on SIT.

Zhou Zi han,정진섭 한국인사관리학회 2018 한국인사관리학회 학술대회 발표논문집 Vol.2018 No.1

최근 각국 정부에서 주력으로 추진하고 있는 바이오산업은 연구개발비의 비중이 크고 원천기술 확보가 중요한 기술집약적 고부가가치 산업으로서, 전 세계 주요 정부들이 전략적으로 육성하고 있는 산업 중 하나이다. 하버드대 Poter(1990) 교수는 자기 저서인 ‘The Competitive Advantage of Nations 에서, 클러스터(Cluster)를 통한 경쟁력 향상을 강조한 바 있다. 최근의 클러스터는 Poter 교수가 초기 주장한 클러스터에서 많이 진화되어 국제화, 산업간 융합, 4차 산업혁명 기술 등이 강조되고 있으나, 여전히 어떤 산업의 경쟁력 강화를 위한 중요한 구조임에는 틀림없다. 본 연구에서는 한국과 중국의 바이오산업 발전을 위해서 바이오클러스터의 현황파악 및 핵심적 영향 요인을 도출하고, 그러한 영향 요인들이 바이오기업 및 클러스터의 성과에 미치는 효과까지 실증하고자 한다. 또한 현재 선진국과 기술 격차가 큰 한국과 중국의 바이오 산업 발전을 위해 해외 자본력, 기술력, 인적자원, 경영노하우를 도입할 수 있는 ‘외국인 투자유치(Inward FDI)’와 ‘4차 산업혁명 기술의 도입’이 바이오클러스터의 발전에 어떠한 영향을 주는지도 고찰하고자한다.

An Ultra-narrow Bandwidth Filter for Daytime Wind Measurement of Direct Detection Rayleigh Lidar

Han, Fei,Liu, Hengjia,Sun, Dongsong,Han, Yuli,Zhou, Anran,Zhang, Nannan,Chu, Jiaqi,Zheng, Jun,Jiang, Shan,Wang, Yuanzu Optical Society of Korea 2020 Current Optics and Photonics Vol.4 No.1

A Rayleigh Lidar used for wind detection works by transmitting laser pulses to the atmosphere and receiving backscattering signals from molecules. Because of the weak backscattering signals, a lidar usually uses a high sensitivity photomultiplier as detector and photon counting technology for signal collection. The capturing of returned extremely weak backscattering signals requires the lidar to work on dark background with a long time accumulation to get high signal-to-noise ratio (SNR). Because of the strong solar background during the day, the SNR of lidar during daytime is much lower than that during nighttime, the altitude and accuracy of detection are also restricted greatly. Therefore this article describes an ultra-narrow bandwidth filter (UNBF) that has been developed on 354.7 nm wavelength of laser. The UNBF is used for suppressing the strong solar background that degrades the performance of Rayleigh wind lidar during daytime. The optical structure of UNBF consists of an interference filter (IF), a low resolution Fabry-Perot interferometer (FPI) and a high resolution FPI. The parameters of each optical component of the UNBF are presented in this article. The transmission curve of the aligned UNBF is measured with a tunable laser. Contrasting the result of with-UNBF and with-IF shows that the solar background received by a Licel transient recorder decreases by 50~100 times and that the SNR with-UNBF was improved by 3 times in the altitude range (35 km to 40 km) compared to with-IF at 10:26 to 10:38 on August 29, 2018. By the SNR comparison at four different times of one day, the ratio-values are larger than 1 over the altitude range (25~50 km) in general, the results illustrate that the SNR with-UNBF is better than that with-IF for Rayleigh Lidar during daytime and they demonstrate the effective improvements of solar background restriction of UNBF.
