( Pei Pei Li ),( Dong Dong Zhang ),( Xiao Juan Wang ),( Xiao Fen Wang ),( Zong Jun Cui1 ) 한국미생물 · 생명공학회 2012 Journal of microbiology and biotechnology Vol.22 No.1

A cellulose-degrading composite microbial system containing a mixture of microbes was previously shown to demonstrate a high straw-degrading capacity. To estimate its potential utilization as an inoculant to accelerate straw biodegradation after returning straw to the field, two cellulose-degrading composite microbial systems named ADS3 and WSD5 were inoculated into wheat straw-amended soil in the laboratory. The microbial survival of the inoculant was confirmed by a denaturing gradient gel electrophoresis (DGGE) analysis, whereas the enhancement of straw degradation in soil was assessed by measuring the mineralization of the soil organic matter and the soil cellulase activity. The results indicated that most of the DGGE bands from ADS3 were detected after inoculation into straw-amended autoclaved soil, yet only certain bands from ADS3 and WSD5 were detected after inoculation into straw-amended non-autoclaved soil during five weeks of incubation; some bands were detected during the first two weeks after inoculation, and then disappeared in later stages. Organic matter mineralization was significantly higher in the soil inoculants ADS3 and WSD5 than in the uninoculated controls during the first week, yet the enhanced degradation did not persist during the subsequent incubation. Similar to the increase in soil organic matter, the cellulase activity also increased during the first week in the ADS3 and WSD5 treatments, yet decreased during the remainder of the incubation period. Thus, it was concluded that, although the survival and performance of the two inoculants did not persist in the soil, a significant enhancement of degradation was present during the early stage of incubation.

CUI JINGHUAN(Jinghuan Cui),김동호(Dongho Kim) 한국열린교육학회 2023 열린교육연구 Vol.31 No.3

비대면 학습의 일상화와 함께 동영상 학습에 관한 관심이 급격하게 높아지고 있다. 이에 본 연구는 하위목표와 자기모니터링 원리를 적용하여 동영상 콘텐츠를 개발하였고 효과를 살펴보았다. 설계된 동영상 콘텐츠의 효과를 살펴보기 위하여 학습자의 동영상 몰입, 수업 흥미도, 수업 두려움, 자기효능감, 학습 이해도의 사전 점수와 사후 점수를 실험 전과 후로 자기보고식 설문조사를 실시하였다. S 대학에 재학 중인 20명의 학습자를 대상으로 수집된 자료를 바탕으로 기술통계 분석과 대응표본 t검증(Paired Samples t-test)을 실시하여 동영상 콘텐츠의 효과를 분석하였다. 이에 따른 연구결과는 첫째, 설계된 동영상 콘텐츠 학습을 통하여 동영상 몰입, 수업 흥미도, 자기효능감 요인에서 사전 검사 점수는 사후 검사 점수보다 향상되었고, 수업 두려움 점수는 줄어들었다. 둘째, 하위목표와 자기모니터링 원리를 활용한 동영상 콘텐츠는 학습자의 학습 이해도 향상에 효과를 미치는 것으로 확인되었다. 이러한 연구결과를 바탕으로 온라인 동영상 기반학습에서 동영상 설계를 위한 시사점을 제언하였다. The popularity of video learning is rising quickly as non-face-to-face learning becomes more commonplace. So, using the concepts of subgoals and self-monitoring, this study created video content and evaluated the success of it. A self-report survey measuring the pre-scores and post-scores of learners' video engagement, class interest, class anxiety, self-efficacy, and academic achievement was carried out before and after the experiment to assess the efficacy of the intended video material. The efficiency of the video content was examined using descriptive statistics and Paired Samples t-test on the information gathered from 20 students enrolled in University S. The findings revealed two main trends. First, the pretest scores for video engagement, class interest, and self-efficacy factors improved in comparison to the posttest scores, and the class anxiety score reduced because of learning the prepared video content. Second, it was discovered that using subgoals and self-monitoring concepts in video content improved learners' understanding of what they were learning. These conclusions lead to suggestions for video design in online video-based learning.

Zhe Cui(Zhe Cui),Yan Zhou(Yan Zhou),Yeong-Gug Kim(Yeong-Gug Kim) The International Academy of Global Business and T 2023 The International Academy of Global Business and T Vol.19 No.2

Purpose - The current study focuses on the effects of different degrees of attention to information provided by VR tourism. The purpose of this study was to explore the impact of VR tourism on potential tourists’ intention to visit, and provided an analysis of how information about a tourist destination moderates VR users’ perceived value and intention to visit. Design/Methodology/Approach - The study uses the SPSS 26.0 and AMOS 26.0 statistical packages to analyze a sample of 328 respondents are analyzed using structural equation modeling. Findings - The results suggest that usefulness, ease of use, enjoyment, interactions among the perceived benefits of VR tourism has a positive effect on perceived value except for Presence. Perceived value is positively correlated with intention to visit intention. Perception of value experience has a significant positive impact on the intention to visit a tourist destination. However, while the overall intention to visit is higher with high involvement, increasing experience with tourism has little influence on the intention to visit. Research Implications - The study found that the perceived value of the VR experience has a direct and significant positive impact on the intention to visit, such that a good perception of value in the experience is a driving factor in users’ visit a tourism destination. The implications of this study for future research are discussed.

Biotoxins for Cancer Therapy

Liu, Cui-Cui,Yang, Hao,Zhang, Ling-Ling,Zhang, Qian,Chen, Bo,Wang, Yi Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.12

In recent times, a number of studies have provided evidence that biotoxins present great potential as antitumor agents, such as snake venom, bee venom, some bacteria toxins and plant toxins, and thus could be used as chemotherapeutic agents against tumors. The biodiversity of venoms and toxins make them a unique source from which novel anticancer agent may be developed. Biotoxins, also known as natural toxins, include toxic substances produced by plants, animals and microorganisms. Here, we systematically list representative biological toxins that have antitumor properties, involving animal toxins, plant toxins, mycotoxins as well as bacterial toxins. In this review, we summarize the current knowledge involving biotoxins and the active compounds that have anti-cancer activity to induce cytotoxic, antitumor, immunomodulatory, and apoptotic effects in different tumor cells in vivo or in vitro. We also show insights into the molecular and functional evolution of biotoxins.

( Ming Cui(cui Ming ),이승신 ( Seung Sin Lee ),류미현 ( Mi Hyun Ryu ) 한국소비자학회 2014 소비자학연구 Vol.25 No.6

본 연구는 소비자의 TV홈쇼핑의 재이용여부를 예측하기 위하여 Davis가 개발한 기술수용모델을 변형 ·확정하여 소비가치가 지각된 이용용이성, 유용성, 만족도와 재구매의도에 미치는 영향을 파악하며, 소비가치와 수용, 만족도와 재구매의도 간의 관계를 탐색해 보았다. 설문조사를 실시하여 최종 501부를 분석에 사용하였으며 구조방정식모형을 통하여 연구가설을 검증하였다. 연구 결과를 요약하면, TV홈쇼핑에 대한 세 가지 소비가치는 지각된 이용용이성과 유용성에 정적인 영향을 미치며, 편의적 가치가 지각된 이용 용이성에 미치는 영향력이 가장 크고, 경제적 가 치는 지각된 유용성에 미치는 영향력이 가장 높았다. 또한 지각된 이용용이성과 지각된 유용성은 만족도에 정적인 영향을 주고, 유용성과 만족도는 재구매의도에 정적인 영향을 주었으므로 TV홈쇼핑의 시스템 개선을 통하여 소비자의 수용, 만족과 재구매의도를 높일 수 있을 것이다. In order to predict the consumers`` repurchasing behavior on TV home shopping, we expanded Davis``s technology acceptance mode (TAM) by using the consumers`` perceived ease of use, perceived usefulness, satisfaction, and repurchase intentions. The present research demonstrated the consumption value is a multidimensional definition construct, and could be divided into three elements, namely economic value, convenience value and hedonic value. Five-hundred and one Korean adult consumers, who purchased products or service on TV home shopping last twelve months, were invited to take part in the online investigation. Data analyses were conducted by descriptive statistical analysis, reliability test, confirmatory factor analysis (CFA) and structural equation modeling (SEM) with SPSS ver. 21.0 and AMOS ver. 21.0. Empirical verification through verifying seven major hypotheses indicate that the data offer substantial supports. First, all the three components of consumption value represent the positive influence on perceived ease of use, and the convenience value has the strongest influence. Only economic value and hedonic value showed significant effect on perceived usefulness, and economic value was much more influential. Second, the perceived ease of use influenced the perceived usefulness positively, and both of which show positive effect on the satisfaction, the perceived usefulness and satisfaction affected the repurchase intentions directly.

Hang-Hang Cui(Hang-Hang Cui),Hyeok-Gi Kwon(Hyeok-Gi Kwon) The International Academy of Global Business and T 2023 The International Academy of Global Business and T Vol.19 No.3

Purpose - In the face of an increasingly competitive business environment and the growing complexity and dynamism of work activities, employee voice and creative behaviors are essential to organizational growth and survival. Consequently, this study examines how to increase voice and creative behaviors in organizational life using transformational leadership and transactional leadership as the entry points, and selecting job crafting as the mediating variable. Design/Methodology/Approach - A hypothesized model was developed to examine the relationship between the constructs. The sample for the study comprised 364 Chinese employees. Data were analyzed using SPSS and structural equation modelling in AMOS. Findings - Transformational leadership and transactional leadership positively impact job crafting, voice behavior, and creative behavior, complementing the existing theory. Furthermore, this study finds that through job crafting, transformational leadership has an enhanced impact on voice and creative behaviors. Research Implications - Transformational leadership and transactional leadership are two separate and complementary types of leadership. Therefore, organizations should develop leaders that can flexibly use both styles to improve leadership effectiveness. Furthermore, the organization should pay more attention to employee job crafting, voice behavior, and creative behavior. Organizations or supervisors should appropriately grant employees work autonomy to respond to the rapidly changing external environment.
