Drosophila suzukii (Diptera: Drosophilidae) is one of the very few Drosophila species which are able to lay eggs and feed on healthy ripening fruit. Adults and larvae are all able to obtain the nutrition in the decaying food, which will generate many microorganisms. However, the relationship between D. suzukii and microorganism is poorly understood. In this study, 13 species of fungi were identified in an artificial diet fed by D. suzukii. Short-term and continuously life table experiments were conducted to determine the impact of three of these fungus species including Geotrichum candidum, Talaromyces minioluteus and Actinomucor elegans on the growth and development of Drosophila suzukii. Results revealed that, compared to the control, G. candidum, T.minioluteus and A. elegans increased the mortality of D. suzukii adults in the short time, while extended the developmental time of pupal D. suzukii by 18.00%, 16.22% and 26.44%, respectively in the life table experiment. T. minioluteus reduced the total longevity of D. suzukii by 15.52%, while A. elegans enhanced the total longevity by 25.96%. G. candidum and A. elegans increased the fecundity bymore than two folds. T. minioluteus elongated the mean generation time (T) by 31.34%, whereas G. candidum shortened it by 15.26% but increased the net reproductive rate (R0) by 217.76%, intrinsic rate of increase (r) by 88.89% and finite rate of increase (λ) by 9.17%. It was concluded that G. candidumand A. elegans significantly had the beneficial effect on the growth and reproduction of D. suzukii, however, T. minioluteus had the negative effect on D. suzukii. Our results could provide a new integrated pest management strategy for D. suzukii which would be discussed in this study.

( Huan Luo ),( Zhen Zhou Xia ),( Yun Yun Chen ),( Yi Zhou ),( Jian Xin Deng ) 한국균학회 2018 Mycobiology Vol.46 No.3

Chrysanthemum coronarium is an economically important plant in Asia, and used medicinally, ornamentally and as a vegetable. In April 2017, leaf spot disease on C. coronarium was observed in Shiyan, Hubei, China. A single-spore isolate was obtained and identified based on morphology and sequence analysis using four regions (rDNA ITS, GAPDH, EF-1a, and RPB2). The results indicated that the fungus is Alternaria argyranthemi. The pathogenicity tests revealed that the species could cause severe leaf spot and blight disease on the host. This is the first report of leaf spot disease on C. coronarium caused by A. argyranthemi in the world, which is also a new record of Alternaria species in China.

Thyroid-Associated Orbitopathy: Evaluating Microstructural Changes of Extraocular Muscles and Optic Nerves Using Readout-Segmented Echo-Planar Imaging-Based Diffusion Tensor Imaging

Huan-Huan Chen,Hao Hu,Wen Chen,Dai Cui,Xiao-Quan Xu,Fei-Yun Wu,Tao Yang 대한영상의학회 2020 Korean Journal of Radiology Vol.21 No.3

Objective: We aimed to investigate the ability of readout-segmented echo-planar imaging (rs-EPI)-based diffusion tensor imaging (DTI) in assessing the microstructural change of extraocular muscles (EOMs) and optic nerves in patients with thyroidassociated orbitopathy (TAO) as well as in evaluating disease activity. Materials and Methods: We enrolled 35 TAO patients and 22 healthy controls (HCs) who underwent pre-treatment rs-EPIbased DTI. Mean, axial, and radial diffusivity (MD, AD, and RD) and fractional anisotropy (FA) of the medial and lateral EOMs and optic nerve for each orbit were calculated and compared between TAO and HC groups and between active and inactive TAO groups. Factors such as age, sex, disease duration, mediation, and smoking history between groups were also compared. Logistic regression analysis was used to evaluate the predictive value of significant variables for disease activity. Results: Disease duration was significantly shorter in active TAOs than in inactive ones (p < 0.001). TAO patients showed significantly lower FA and higher MD, AD, and RD than HCs for both medial and lateral EOMs (p < 0.001), but not the AD value of lateral EOMs (p = 0.619). Active patients had significantly higher FA, MD, and AD than inactive patients for medial EOMs (p < 0.005), whereas only FA differed significantly in the lateral EOMs (p = 0.018). The MD, AD, and RD of optic nerves were significantly lower in TAO patients than HCs (p < 0.05), except for FA (p = 0.129). Multivariate analysis showed that the MD of medial EOMs and disease duration were significant predictors for disease activity. The combination of these two parameters showed optimal diagnostic efficiency for disease activity (area under the curve, 0.855; sensitivity, 68.4%; specificity, 96.9%). Conclusion: rs-EPI-based DTI is promising in assessing microstructural changes of EOMs and optic nerves and can help to indicate the disease activity of TAO, especially through the MD of medial EOMs.

Huan Yun,Xiao Long Xin,Xiao Fei Yang,Ling Ling Mao 원광대학교 기초자연과학연구소 2024 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.27 No.1

In this paper, we focus on ideals and prime ideals of $CKL$-algebras and applications of prime ideals of $CKL$-algebras. Firstly, we prove that any self-distributive $L$-algebra is a $CKL$-algebra. Conversely, we give an example of $CKL$-algebras that is not a self-distributive $L$-algebra. Furthermore, we give a generation formula of ideals on $CKL$-algebras. Secondly, we give some equivalent descriptions of prime ideals and its properties on $CKL$-algebras. We mainly prove that maximal ideals are prime ideals on $CKL$-algebras. Next, we give a counterexample to show that commutative L-algebras may be not residuated lattices, much less $MV$-algebras. The results show that commutative L-algebras are a true promotion of $MV$-algebras. Therefore, we study some properties of commutative $L$-algebras.

오늘 날 4 차 산업혁명으로 명명되는 기술적 융합과 디지털 신기술의 태동으로 인간의 노동을 대체할 수 있는 인공지능의 등장은 인간의 가치가 창의적인 사고에 있음을 다시금 깨닫게 하고 있다. 이와 같은 환경의 병화에서 많은 조직과 기업들은 창의적인 사고, 지식 공유 등을 통하여 고유한 가치를 개발하고 발전시키기 위해 노력하고 있다. 조직 내 창의성은 단순히 창의적인 개인으로 인하여 만들어 질 수 있는 것이 아니라, 구성원이 창의적일 수 있는 조직문화가 중요하다. 많은 연구에서는 리더의 역할이 조직문화 조성에 중요한 기반으로 보고 있다. 본 연구에서는 변혁적 리더십과 거래적 리더십의 개념 및 구성요소에 대한 명확한 설명을 토대로 팔로어의 창의성과 리더십의 관계를 검증하고자 한다. 기존에 연구된 리더십과 창의성의 관계에 팔로어의 정체성을 매개변수로, 지각된 조직지원인식을 조절변수로 하여 보다 포괄적인 관계를 알 수 있을 것으로 생각한다. 연구를 위해 중국 북경과 상하이의 기업을 대상으로 설문을 실시하여 242 부의 설문지를 통계에 사용하였다. 가설검증 결과 변혁적 리더십과 거래적 리더십은 오두 팔로어의 창의성에 긍정적인 영향이 있는 것으로 나타났다. 또한 팔로어의 정체성이 리더십과 팔로어의 창의성의 관계를 매개하고 있으며, 리더십과 팔로어의 관계적 정체성은 지각된 조직지원인식에 의해 조절되고 있었다. 이와 같은 연구결과를 바탕으로 연구의 시사점, 한계점 및 향후의 연구 방향이 제시되었다. The importance of creativity to an organization and society is undeniable, simultaneously, leadership is a key factor affecting the creativity of followers within an organization. Based on the clarification of the concepts and dimensions of transformational leadership and transactional leadership, this paper examined follower identifications as a mediator and employees’ perceptions of organizational support as a moderator in the relationship between leadership and follower creativity. Using a sample of 242 employees who engaged in manufacturing working in Beijing and Shanghai, China, we found that most of our hypotheses were supported. Specifically, results showed that follower identifications mediate the positive influence relationship between leadership on follower creativity, and follower’s perceived organizational support moderate both transformational leadership and transactional leadership in the relationship with follower relational identification. Implications of the findings, Limitations of the study and directions for future research are discussed.

Liu, Xiao-Yun,Zhu, Li-Jun,Cui, Dai,Wang, Zhi-Xiao,Chen, Huan-Huan,Duan, Yu,Shen, Mei-Ping,Zhang, Zhi-Hong,Wang, Xiao-Dong,Chen, Jia-Wei,Alexander, Erik Karl,Yang, Tao Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.14

A large proportion of patients with thyroid nodules in China undergo thyroidectomy in order to get confirmatory histology diagnosis. The financial impact of this modality remains to be investigated. To evaluate rationality of performing thyroidectomy without a routine FNA preoperatively from the economic perspective, we conducted a retrospective, observational study of all archival thyroidectomies with records of cost per stay (CPS), cost per day (CPD) and length of stay (LOS) from 2008 to 2013 in the First Affiliated Hospital of Nanjing Medical University. We compared all the parameters between cancer and non-cancer thyroidectomies. We recruited 6, 140 thyroidectomies with valid records of CPS, CPD and LOS in this period. The CPS of cancer thyroidectomy was significantly higher than non-cancer thyroidectomy. The percentage of cancer thyroidectomy increased from 26.5% to 41.6%. The percentage of annual cost of cancer thyroidectomies rose from 30.2% to 45.2%. The LOS for cancer and non-cancer thyroidectomy decreased while the CPD increased in the past six years. The estimated national cost in 2012 for all thyroidectomies would be USD 1.86 billion with USD 1.09 billion for non-cancer thyroidectomies. We have witnessed great improvement in the healthcare for patients with thyroid nodules in China. However, given limited healthcare resources, currently thyroid FNA for more precise preoperative diagnosis may help to curb the rapidly increasing demand in healthcare costs in the future for nodular thyroid disease in China.

Huan, Meng,Kang, Yun-Jeong,Lee, Sang-won,Choi, Dong-Oun The Institute of Internet 2021 International journal of advanced smart convergenc Vol.10 No.2

With the rapid development of artificial intelligence and big data, a lot of medical data is effectively used, and the diagnosis and analysis of diseases has entered the era of intelligence. With the increasing public health awareness, ordinary citizens have also put forward new demands for panic disorder health services. Specifically, people hope to predict the risk of panic disorder as soon as possible and grasp their own condition without leaving home. Against this backdrop, the smart health industry comes into being. In the Internet age, a lot of panic disorder health data has been accumulated, such as diagnostic records, medical record information and electronic files. At the same time, various health monitoring devices emerge one after another, enabling the collection and storage of personal daily health information at any time. How to use the above data to provide people with convenient panic disorder self-assessment services and reduce the incidence of panic disorder in China has become an urgent problem to be solved. In order to solve this problem, this research applies the context awareness to the automatic diagnosis of human diseases. While helping patients find diseases early and get treatment timely, it can effectively assist doctors in making correct diagnosis of diseases and reduce the probability of misdiagnosis and missed diagnosis.
