중국은 비약적인 경제 발전과 함께 서비스 산업이 전체 산업에서 차지하는 비중이 증가함에 따라 서비스의 질이 점차 중요해지고 있다. 특히 중국의 여러 서비스 산업 가운데 통신회사의 서비스부문이 가장 앞서고 있다. 서비스의 질은 서비스 산업에서 종사하는 직원들에 의해서 결정된다. 그런데 서비스에 종사하는 직원들은 감정노동에 드러나 있다. 그러므로 중국 통신회사 직원들의 감정노동에 대한 연구가 필요하다. 본 연구는 중국 통신회사 직원들의 감정노동이 직무소진에 미치는 영향과 사회적 지지에 따라 감정노동과 직무소진의 조절 작용을 연구했다. SPSS18.0을 활용함으로써 연구결과가 도출되었다. 즉 심층행위와 표면행위가 감정적 고갈에 정(+)의 영향을 미치고 표면행위가 비인격화에 정(+)의 영향을 미치며 심층행위가 자아성취감 저하에 부(-)의 영향을 미친다. 마지막으로 연구결과를 바탕으로 한 시사점을 제시하였다. 즉 회사측면에서 표면행위를 심층행위로 전환시키는 훈련프로그램이 필요하고 비정규직에 대한 고용불안 해소, 임금 및 복리후생을 개선되어야 할 것이며 정신건강 예방관리 프로그램을 운영할 필요가 있다. 또한 회사는 직원들의 의식수준을 높이기 위해서 교육 프로그램을 실행해야 하며 비정규직 직원들의 과소평가를 해소하기 위해서 특별수당을 지급하고 최대한 동등하게 대해야 하는 동시에 상사와 동료의 지지를 얻을 수 있는 조화로운 분위기를 조성해야 한다. With the development of China’s economy, the proportion of the service industry in China is getting bigger and bigger, so the quality of service in the service industry is becoming more important. The service industry is different from the primary industry and the secondary industry. The product of the service industry is service, The service is provided by the staff, so the staff plays an important role in the process of the service industry development. In China, the typical service industry are telecommunication companies. In this case, it is necessary to do research on the work of the staff of telecommunication companies. In this study, the object of research are the temporary employees of the Chinese telecommunication companies. We need find what relationship exists between the emotional labor and the burnout of employees, and the effect of the social support between the emotional labor and the burnout. The results of this study suggest that in the service industry, the staff who does the deep acting has less burnout than the staff who does the surface acting. Moreover social support has a moderating effect between emotional labor and the burnout. Even the Supervisor support is stronger than colleague support.

This study empirically examines the mediating effect of work-life balance and moderated mediating effect of sense of humor between self-esteem, ego-resilience and job satisfaction. in the case of Chinese employees working for multinational enterprises. The data captured from October 2014 to December 2014, and we obtained the 364 usable responses from 387 employees. The authors provide strong empirical supports for a mediating effect of work-life balance between self-esteem, ego-resilience and job satisfaction. In addition, a good sense of humor positively moderated the relationship between self-esteem and work-Life balance. Meanwhile, humor influenced the relationship between self-esteem, ego-resilience and worklife balance. Upon inclusion of sense of humor, we find that sense of humor positively moderated mediate the relationship among self-esteem, ego-resilience and job satisfaction. Thus, we suggest that managers provide training programs focusing on developing or boosting self-esteem and ego-resilience for employees to increase their job satisfaction. Moreover the human resource (HR) department should recruit employees who possess high self-esteem, ego-resilience and sense of humor. We also suggest that in pursuit of research about work-life balance, we should consider psychological capital such as self-esteem, ego-Resilience.

This paper describes the development and result of ground experiment and analyzes the on-orbit operation of Loop heat pipes (LHP) for the Chinese circumlunar return and reentry spacecraft. A novel LHP was developed to satisfy the thermal control requirements of Inertial measurement units (IMU). The LHP consisted of an integrated evaporator subassembly, a cambered condenser, and an electric explosion valve. Ground experiments were conducted to investigate the startup characteristics, and heat transfer and heat insulation performance of the LHPs. During a flight mission, the LHPs work as a thermal switch and perform both heat transfer and insulation functions. Before returning to the earth’s atmosphere, the valves of the reentry capsule are opened to discharge working fluid and prevent heat transfer from the capsule wall to the devices. In the flight mission, the LHPs performed all the required functions, and the IMU temperatures were maintained within an allowable range.

Ting Yuan,Tengfei Huo,Haie Huo,Xianjie Fang,Lilin Li,Miao Chen,Li Yu 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.11

Social stability risk posed by energy infrastructure projects can seriously affect urban sustainable development. There is thus a need to better understand how risk strategies are designed. However, there is few considerations on risk strategy design by breaking causal relationships. This research innovatively explores social stability risk variables by content mining, develops causal relationships of the social stability risk variables via Fault Tree Analysis (FTA) method, explores core risk variables and critical causal relationships by social network analysis (SNA) method, designs and validates risk strategies. The findings show that: 1) From the overall risk network perspective, the risk network contain 8 core risk variables. 2) From individual risk network perspective, there are 75 critical causal relationships. The top 3 critical causal relationships contain: projects that destroy the cultural landscape would be regarded as threating national security, which often inspires demonstrations among the local people and the line betweenness is the largest (35.589). Traffic congestion by the project is the main reason to cause local small-scale public petition, and the line betweenness is 35.075. Projects that threaten the ecological environment often bring psychological rejection of the project by the local public, and the line betweenness is 30.837. 3) Two scenarios are evaluated in terms of basic scenario and the experiment group scenario. Compared with the basic scenario, risk strategies considering causal relationships have significant effectiveness. The overall risk network density has reduced by 35.22%. The clustering coefficients has decreased by 16.20%. Intermediate central potential has reduced by 9.49%. This study offers a good reference for project managers to complete the sustainable risk control.

In order to solve the shortage of natural Tripterygium wilfordii Hook. f. plant resource for the production of the important secondary metabolites triptolide and wilforine, hairy roots were induced from its root calli by Agrobacterium rhizogenes. Induced hairy roots not only could be maintained and grown well in hormone-free half-strength Murashige and Skoog medium but also could produce sufficient amounts of both triptolide and wilforine. Although hairy roots produced approximately 15% less triptolide than adventitious roots and 10% less wilforine than naturally grown roots, they could grow fast and could be a suitable system for producing both secondary metabolites compared with other tissues. Addition of 50 μM methyl jasmonate (MeJA) could slightly affect hairy root growth, but dramatically stimulated the production of both triptolide and wilforine, whereas 50 μM salicylic acid had no apparent effect on hairy root growth with slightly stimulatory effects on the production of both secondary metabolites. Addition of precursor nicotinic acid, isoleucine, or aspartic acid at the concentration of 500 μM had varying effects on hairy root growth, but none of them had stimulatory effects on triptolide production, and only the former two had slightly beneficial effects on wilforine production. The majority of triptolide produced was secreted into the medium, whereas most of the produced wilforine was retained inside of hairy roots. Our studies provide a promising way to produce triptolide and wilforine in T. wilfordii hairy root cultures combined with MeJA treatment.

Investigation on cavitating flow and parameter effects in a control valve with a perforated cage

Wang, Hong,Zhu, Zhimao,Zhang, Miao,Li, Jie,Huo, Weiqi Korean Nuclear Society 2021 Nuclear Engineering and Technology Vol.53 No.8

Valve is widely used in the various industry areas to adjust and control the flow. Cavitation frequently takes place and sometimes is inevitable in various types of valve to cause the erosion damage. Therefore, how to control and minimize the effect of cavitation is still an important topic. This study numerically investigates the cavitating flow in a control valve with a perforated cage. The effects of some parameters on the cavitation are discussed. It also discusses to use the throttling steps to govern the cavitating flow. The results show that the opening degree of valve and the length of downstream divergent connection both influence the cavitation. The increase of the divergent length reinforces the cavitation. And the larger the opening of valve is, the intenser the cavitation is and the more vapor is present. The more throttling steps are helpful to decrease the cavitation.

New Permeable Structure for Controlling Debris Flows in the Wenjiagou Gully

Yu-feng Liang,Chuan Liang,Hongwei Zhou,Feng-rong Yang,Miao Huo,Jia-wen Zhou 대한토목학회 2018 KSCE JOURNAL OF CIVIL ENGINEERING Vol.22 No.11

Aimed to control debris flows more effectively, we attempt to develop a new structure called a “sloping roof grill dam”, which consists of guidance walls, separation grills and lateral deposit areas. A series of flume tests were performed to verify the function of this new structure, focusing on the trapping efficiency (β ), deceleration efficiency (μ) and coarse-fine sediment separation extents (η) under different conditions of structure and debris flows. Experimental results show that both the trapping and deceleration efficiency increase with a decrease in permeability, whereas the separation extent shown the opposite effect. Multiple regression analysis indicates that β and η are linearly dependent on the permeability, deceleration efficiency and magnitudes of debris flow. In addition, an increase in beam gap can lead to an increase in the impact area downstream for the debris flow after the control of the structure. Finally, a two-level installation of the structure is tested to determine whether there is an enhancement of the debris control, which indicated that although the trapping effect of the two-level structure is considerably greater than that of a single-level structure (2.11 times at maximum), the separation extent of the two-level structure is not distinct and may be even lower.

Matrix metalloproteinases (MMPs) degrade various components of the extracellular matrix and functional polymorphisms in encoding genes may contribute to genetic susceptibility to many cancers. Up to now, associations between MMP-7 (-181A>G) and digestive system cancer risk have remained inconclusive. To better understand the role of the MMP-7 (-181A>G) genotype in digestive cancer development, we conducted this comprehensive meta-analysis encompassing 3,518 cases and 4,596 controls. Overall, the MMP-7 (-181A>G) polymorphism was associated with higher digestive system cancer risk on homozygote comparison (GG vs. AA, OR=1.21, 95% CI = 1.12-1.60) and in a dominant model (GG/GA vs. AA, OR=1.16, 95% CI =1.03-1.46). On subgroup analysis, this polymorphism was significantly linked to higher risks for gastric cancer (GG vs. AA, OR=1.22, 95% CI = 1.02-1.46; GA vs. AA, OR=1.82, 95% CI =1.16-2.87; GG/GA vs. AA, OR=1.13, 95% CI =1.01-1.27; GG vs. GA/AA, OR= 1.25, 95% CI = 1.06-2.39. We also observed increased susceptibility to colorectal cancer and esophageal SCC in both homozygote (OR = 1.13, 95% CI = 1.06-1.26) and heterozygote comparisons (OR = 1.45, 95% CI = 1.11-1.91). In the stratified analysis by controls, significant effects were only observed in population-based studies (GA vs. AA, OR=1.16, 95% CI=1.08-1.50; GA/AA vs. GG, OR=1.10, 95% CI=1.01-1.72). According to the source of ethnicity, a significantly increased risk was found among Asian populations in the homozygote model (GG vs. AA, OR=1.40, 95% CI=1.12-1.69), heterozygote model (GA vs. AA, OR=1.26, 95% CI=1.02-1.51), and dominant model (GG/GA vs. AA, OR=1.18, 95% CI=1.08-1.55). Our findings suggest that the MMP-7 (-181A>G) polymorphism may be a risk factor for digestive system cancer, especially among Asian populations.

Zhang, Jun-Feng,Hua, Rong,Sun, Yong-Wei,Liu, Wei,Huo, Yan-Miao,Liu, De-Jun,Li, Jiao Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.9

Background: Perineural invasion (PNI) has been reported as one of the sources of locoregional recurrence in resected pancreatic cancer (PC). However the impact of PNI in resected pancreatic cancer remains controversial. The purpose of this study was to determine the association between PNI status and clinical outcomes. Methods: Publications were identified which assessed prognostic significance of PNI status in resected pancreatic cancer up to February 2013. A meta-analysis was performed to clarify the association between PNI status and clinical outcomes. Results: A total of 21 studies met the inclusion criteria, covering 4,459 cases. Analysis of these data showed that intrapancreatic PNI was correlated with reduced overall survival only in resected pancreatic ductal adenocarcinoma (PDAC) patients (HR=1.982, 95%CI: 1.526-2.574, p=0.000). Extrapancreatic PNI was correlated with reduced overall survival in all resected pancreatic cancer patients (HR=1.748, 95%CI: 1.372-2.228, p=0.000). Moreover, intrapancreatic PNI status may be associated with tumor recurrence in all resected pancreatic cancer patients (HR=2.714, 95%CI: 1.885-3.906, p=0.000). Conclusion: PNI was an independent and poor prognostic factor in resected PDAC patients. Moreover, intrapancreatic PNI status may be associated with tumor recurrence.

Bai, Yun-Lu,Zhou, Bing,Jing, Xiao-Yue,Zhang, Bin,Huo, Xiao-Qing,Ma, Chao,He, Jian-Miao Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.10

Objective: To evaluate the predictive value of GST gene polymorphisms with regard to prognosis of breast cancer patients receiving neoadjuvant chemotherapy. Methods: A total of 159 patients were included in our study between January 2005 and January 2007. All the patients were followed up until January 2012. Genotyping was based upon the duplex polymerase-chain-reaction with the PCR-CTPP method. Results: Patients with null GSTM1 and GSTP1 Val/Val genotypes had significantly had better response rates to chemotherapy when compared with non-null GSTM1 and GSTP1 Ile/Ile genotypes (OR=1.96 and OR=2.14, respectively). Patients with the GSTM1 null genotype had a longer average survival time and significantly lower risk of death than did those with non-null genotypes (HR=0.66). Similarly, those carrying the GSTP1 Val/Val genotype had 0.54-fold the risk of death of those with GSTP1 Ile/Ile (HR=0.54). Conclusion: A significant association was found between GSTM1 and GSTP1 gene polymorphisms and clinical outcomes in breast cancer cases.
