세계경제와 사회생활중 비영리조직의 중요성은 점점 부각되고 있으며, 전통적으로 제3부분으로 구분되어진다. 정부가 제1부문, 사영기업이 제2부문, 비영리조직이 제3부문으로 구분되어지며, 두 가지 조직으로 진화되기 시작한다. 그 첫 번째 종류는 열리조직 즉 기업이며, 두 번째 종류는 비영리조직이라 통칭하며, 정부 비영리집단과 사영기업 비영리집단이 포함된다. 지식경제와 서비스경제 시대가 도래한 현실에서, 두 종류의 비영리 서비스조직의 구분과 그 경영 및 경영자가 처한 상황은 비교적 심오한 理論 의의와 현실 의의를 구비한 도전에 직면해 있다. 본 연구는 서비스 경영의 각도에서 중국의 각종 사회기구(비영리조직)를 발전시키고 관리하기 위한 전략적 계시를 제공하고, 국내기업(영리집단)이 단기이익관을 초월하여 장기적 영리능력의 구축할 수 있도록 하고, 비영리와 서비스의 관접에서 중국의 정부기구의 정책행위에 전략적 신사고와 의사결정 상의 참고자료를 제공하고자 한다.

서비스기업의 고객관리

張金成,楊坤 啓明大學校 産業經營硏究所 2002 經營經濟 Vol.35 No.2

서비스의 가장 중요한 특징의 하나가 바로 고객 참여이다. 서비스 질 또한 중요하게 고객의 인식된 질로 표현되는 것이지 서비스 시스템의 운영된 질이 아니다. 그러나 서비스의 저장 불가능성과 이질성은 서비스로 하여금 기본적으로 서비스 시스템의 제한된 서비스 능력으로써 고객의 다양화한 서비스 수요, 참여행위와 인식된 결과에 대응하게 한다. 그래서 서비스관리의 boundary는 조직boundary에만 멈출 것이 아니라 앞으로 곧, 혹은 지금 한창, 혹은 이미 조직과 서비스 관계를 수립한 고객에게도 적극적이고 과학적인 관리를 실행해야 한다. 이것이 혹시 서비스 관리가 생산관리와 구별되는 하나의 선명한 특징일지도 모른다. 본문에서는 서비스 기업의 고객관리 문제에 대해 비교적 깊은 탐구적 토론을 진행하고자 한다. An important trait of service is the participation of customers in the service process, and the quality of service is mainly represented by the customer's perception quality, rather than by the service system operation quality. However, the simultaneous production and consumption as well as the heterogeneity of service make the service companies have to face the diversified customer's demands, participation behaviors, and perception results with the limited capacity of the service system. Therefore, the service management should not stop at the boundary of the nature service organization. The active and scientific management should be applied to the customers who are going to have, or are having, of have had service relationships with the service organizations. This may be one of signigicant different characteristics between service management and production management. This article intends to make a deep discussion about the problem of customer management.

Effect of wind time on the dispersal capacity of Trichogramma dendrolimi Matsumura (Hymenoptera Trichogrammatidae)

Jin-cheng Zhou,Qian-jin Dong,Tong-shu Zhang,Li-jia Duan,Su-fang Ning,Quanquan Liu,Yuan-yuan Li,Chun-xue Li,Hui Dong 한국응용곤충학회 2019 Journal of Asia-Pacific Entomology Vol.22 No.3

The efficacy of Trichogramma against pests basically depends on the dispersal capacity of the wasps. A releaserecapture method was used in this study to evaluate the effect of relative wind speed (RWS) during the nighttime and the daytime on the dispersal capacity of postrelease population of Trichogramma dendrolimi Matsumura. Two repeated measurements were carried out, using sentinel cards with the host eggs and yellow sticky card traps on the third and the sixth day after wasp release. The results showed that: (1) both the number of recaptured wasps and parasitized eggs increased with the RWS in the daytime during the first three days. The number of parasitized eggs also increased with the RWS in the daytime over the latter three days. The distances that encompassed 98% recaptured T. dendrolimi adults (X 98 ) at the first three days was quadratically increased by the RWS of the daytime. (2) The number of wasps recaptured decreased with the distance from the releasing point during the first three days, but it was not influenced by the distance from the releasing point during the latter three days. (3) The average dispersal radius of the wasps during the first three days was shorter than during the latter three days. The present results will be helpful to improve release techniques based on the wind effects at different times.

Mechanistic Insight into Nanoarchitected Ag/Pr₆O₁₁ Catalysts for Efficient CO Oxidation

Zhang, Xinxin,Cheng, Shiyang,Zhang, Wei,Zhang, Cai,Drewett, Nicholas E.,Wang, Xiyang,Wang, Dong,Yoo, Seung Jo,Kim, Jin-Gyu,Zheng, Weitao American Chemical Society 2017 INDUSTRIAL & ENGINEERING CHEMISTRY RESEARCH - Vol.56 No.39

<P>Ag/Pr<SUB>6</SUB>O<SUB>11</SUB> catalysts supported by either Pr<SUB>6</SUB>O<SUB>11</SUB> nanorods (Pr<SUB>6</SUB>O<SUB>11</SUB>-NRs) or nanoparticles (Pr<SUB>6</SUB>O<SUB>11</SUB>-NPs) were prepared by conventional incipient wetness impregnation. The nanocomposite of Ag/Pr<SUB>6</SUB>O<SUB>11</SUB>-NRs demonstrated a higher catalytic activity for CO oxidation than Ag/Pr<SUB>6</SUB>O<SUB>11</SUB>-NPs at lower temperatures. This improved performance may be ascribed to the mesoporous features and resultant oxygen vacancies of the Pr<SUB>6</SUB>O<SUB>11</SUB> nanorods support, as well as the large surface area and homogeneous loading of Ag species. As a result, 98.7 and 100% CO conversions were achieved at 210 and 240 °C for Ag/Pr<SUB>6</SUB>O<SUB>11</SUB>-NRs, while Ag/Pr<SUB>6</SUB>O<SUB>11</SUB>-NPs require a temperature of 320 °C to obtain the 100% CO conversion rate. These findings reveal that Pr<SUB>6</SUB>O<SUB>11</SUB>-NRs is the preferable support, comparative to Pr<SUB>6</SUB>O<SUB>11</SUB>-NPs, for Ag/Pr<SUB>6</SUB>O<SUB>11</SUB> catalysts, for CO oxidation.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/iecred/2017/iecred.2017.56.issue-39/acs.iecr.7b02530/production/images/medium/ie-2017-02530c_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ie7b02530'>ACS Electronic Supporting Info</A></P>

Edaphovirga cremea gen. nov., sp. nov., isolated from the rhizospheric soil of Codonopsis clematidea

Jin-Yan Xue,Meng-Yue Zhang,Yu Zhang,Juan Cheng,Li-Cheng Liu,Ying-Ying Wu,Tian-Yuan Zhang,Yi-xuan Zhang 한국미생물학회 2019 The journal of microbiology Vol.57 No.5

A Gram-negative, facultatively anaerobic, non-motile, nonspore- forming, coccoid or rod-shaped and creamy-pigmented bacterium, designated SYP-B2100T, was isolated from the rhizospheric soil of Codonopsis clematidea in the Xinjiang Uygur Autonomous Region, China. The optimal growth occurred at 28°C, pH 5.0, in the absence of NaCl. The cells tested positive in catalase and methyl red tests but negative in oxidase, urease, gelatinase, milk coagulation, and peptonisation, H2S production, nitrate reduction, and Voges-Proskauer tests. The major isoprenoid quinone was ubiquinone-8 (Q-8). The major cellular fatty acids were C16:0 and summed feature 8. The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, and phosphatidylglycerol. The 16S rRNA gene sequence of strain SYP-B2100T was the most similar to that of Rahnella inusitata DSM 30078T (96.9%) within the family Enterobacteriaceae. The genomic DNA G+C content of strain SYP-B2100T was 50.3 mol%. The combined data from the phylogenetic, morphological, physiological, biochemical, and chemotaxonomic analyses presented in this study support the conclusion that strain SYP-B2100T represents a novel species of a new genus, for which the name Edaphovirga cremea gen. nov., sp. nov. is proposed; the type strain is SYPB2100T (= CGMCC 1.5857T = DSM 105170T = KCTC 62024T).

Influence of "Historical Effects" on the Rheological Properties of a Polyacrylonitrile Copolymer Solution

Yumin Cheng,Huibo Zhang,Shuangkun Zhang,Weiwei Liu,Jing Wang,Run Cheng,SeungKon Ryu,Riguang Jin 한국탄소학회 2013 Carbon Letters Vol.14 No.1

Polyacrylonitrile (PAN) copolymers of different molecular weights were synthesized by a suspension polymerization and precipitation polymerization method. The rheology behaviors of the synthesized PAN copolymers were investigated in relation to their molecular weight, solid content and melting temperature. The influence of "historical effects" on the spinning solution of PAN was studied by analyzing the laws of viscosity considering the diversification time and temperature. The viscosity disciplines of each spinning solution conformed well to the rheological universal laws in a comparison of the suspension polymerization product with that of precipitation polymerization. Viscosity changes in the swelling process of dissolution were gentler in the suspension polymerization product; a small amount of water will quickly debase the solution viscosity, and high-speed mixing can greatly shorten the time required by the spinning solution to reach the final viscosity.

Hu, Cheng-Cheng,Gan, Ping,Zhang, Rui-Ying,Xue, Jin-Xia,Ran, Long-Ke Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.21

Purpose: To identify prostate cancer lncRNAs using a pipeline proposed in this study, which is applicable for the identification of lncRNAs that are differentially expressed in prostate cancer tissues but have a negligible potential to encode proteins. Materials and Methods: We used two publicly available RNA-Seq datasets from normal prostate tissue and prostate cancer. Putative lncRNAs were predicted using the biological technology, then specific lncRNAs of prostate cancer were found by differential expression analysis and co-expression network was constructed by the weighted gene co-expression network analysis. Results: A total of 1,080 lncRNA transcripts were obtained in the RNA-Seq datasets. Three genes (PCA3, C20orf166-AS1 and RP11-267A15.1) showed a significant differential expression in the prostate cancer tissues, and were thus identified as prostate cancer specific lncRNAs. Brown and black modules had significant negative and positive correlations with prostate cancer, respectively. Conclusions: The pipeline proposed in this study is useful for the prediction of prostate cancer specific lncRNAs. Three genes (PCA3, C20orf166-AS1, and RP11-267A15.1) were identified to have a significant differential expression in prostate cancer tissues. However, there have been no published studies to demonstrate the specificity of RP11-267A15.1 in prostate cancer tissues. Thus, the results of this study can provide a new theoretic insight into the identification of prostate cancer specific genes.

Jin Cheng,Bin Wang,Yong Zhang,Zhonghua Wang 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.2

A feedback control law for orientation tracking problem of a mobile robot with N on-axle trailers isproposed in this paper. Based on a recursive designing process, the orientation tracking problem is converted intostabilizing the including angles on the designed reference value. The designing process of the control law is simpleand can be easily extended to any given N trailers system. With input-to-state stability on cascade form system, theclosed-loop system is proven to be asymptotically stable. Simulation experiment on a mobile robot with 4 trailersis implemented and the results demonstrate that the proposed control law works successfully.

Fabrication of Hierarchically Porous Carbon Nanofibers from Immiscible PAN/PVDF Polymer Blends as Electrode Materials

Cheng Gui,Yike Zhang,Rui Jin,Yang Song,Rong Li,Yanjun Xing 한국섬유공학회 2021 Fibers and polymers Vol.22 No.4

Most previous work on the preparation of electrode materials has usually used to grind carbon nanofibers and addnon-reactive binders, which lead to limited surface area and lower electrochemical performance in electrode materials. In thisstudy, porous carbon nanofibers were prepared from non-miscible PAN/PVDF polymer blends by electrospinning andcarbonization to obtain electrode materials with high performance and high specific surface area. In the process of preparingelectrode materials, carbon nanofibers can be directly prepared as electrodes with high-performance and flexibility withoutadding any inactive materials, such as polymer binders or electronic conductors. Results showed that PF-C-50 has themaximum specific surface area of 773 m2 g-1 and the specific capacitance as high as 181 F/g at the current density of 0.4 A/gand 134 F/g at the current density of 1 A/g. PF-C-80 exhibits a specific capacitance as high as 156 F/g at the current densityof 0.4 A/g and 117 F/g at the current density of 1 A/g with the smallest IR drop and Rct. The prepared porous carbonnanofiber electrode improves the electrochemical performance and flexibility of the electrode material. These uniquestructures and characteristic materials can be excellent candidates for high-performance flexible electrodes, laying a goodfoundation for wearable devices.

Taurine Induces Anti-Anxiety by Activating Strychnine-Sensitive Glycine Receptor in vivo

Zhang, Cheng Gao,Kim, Sung-Jin S. Karger AG 2007 Annals of nutrition & metabolism Vol.51 No.4

<P>Taurine has a variety of actions in the body such as cardiotonic, host-defensive, radioprotective and glucose-regulatory effects. However, its action in the central nervous system remains to be characterized. In the present study, we tested to see whether taurine exerts anti-anxiety effects and to explore its mechanism of anti-anxiety activity in vivo. The staircase test and elevated plus maze test were performed to test the anti-anxiety action of taurine. Convulsions induced by strychnine, picrotoxin, yohimbine and isoniazid were tested to explore the mechanism of anti-anxiety activity of taurine. The Rotarod test was performed to test muscle relaxant activity and the passive avoidance test was carried out to test memory activity in response to taurine. Taurine (200 mg/kg, p.o.) significantly reduced rearing numbers in the staircase test while it increased the time spent in the open arms as well as the number of entries to the open arms in the elevated plus maze test, suggesting that it has a significant anti-anxiety activity. Taurine’s action could be due to its binding to and activating of strychnine-sensitive glycine receptor in vivo as it inhibited convulsion caused by strychnine; however, it has little effect on picrotoxin-induced convulsion, suggesting its anti-anxiety activity may not be linked to GABA receptor. It did not alter memory function and muscle activity. Taken together, these results suggest that taurine could be beneficial for the control of anxiety in the clinical situations.</P><P>Copyright © 2007 S. Karger AG, Basel</P>
