Shuangling Li,Ke Yun Qin 원광대학교 기초자연과학연구소 2020 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.19 No.2

Attribute reduction plays an important role in formal concept analysis. The existing work on attribute reduction of fuzzy formal context focuses mainly on one-sided fuzzy formal concepts. This paper is devoted to the study of attribute reduction for general L-fuzzy formal context. Some judgement theorems for a set of attributes to be consistent are presented. By using the discernibility function composed of discernibility attributes between related L-fuzzy formal concepts, an approach to compute attribute reductions is proposed. An illustrative example is presented which justify the method presented in this study.

Reduced graphene oxide (rGO) aqueous dispersions were synthesized from GO suspensions with hydrazine as reducing agent via a microwave-hydrothermal process in ammonia solution. The rGO films were fabricated by vacuum filtration of above dispersions. When the weight ratio of hydrazine to GO (R N2H4/GO) increases from 0.125 to 9, the dispersion stability of rGO nanosheets in hydrazine/ammonia solution degrades gradually, the surfaces of resultant films become rough from smooth and large interspaces turn up in the transverse section. With the increasing of R N2H4/GO, the C/O atomic ratio and orientation degree of (002) plane of rGO films increase, and the in-plane thermal conductivity also increases, achieving a maximum value of 1056 W/m K when R N2H4/GO is 3.375, then decreases because large interspaces in the rGO film with higher reduction degree greatly limit the thermal transport due to the severe phonon scatterings at the sheets boundaries.

소셜미디어 이용이 오프라인 정치 참여에 미치는 영향 연구: 촛불집회 SNS 읽기-쓰기의 매개 효과에 주목하며

This study is to aim to find empirical impacts of social media on political participation. Today, communications through social media such as Twitter, Facebook, Instagram and so on, become more and more important, and particularly evident in political areas. In this vein, recent increasing research curiosity and works are understandable. The case, the Kwanghamun candlelight vigil in 2016-2017, is very timely to answer the questions: what are important variables to influence political reading and writings on social media?; what impacts of social media use on various political participations, especially for former president Park's impeachment? 본 연구는 소셜미디어 이용과 실제 정치참여간 관련성을 실증적으로 살펴보기 위해, 박근혜 전 대통령의 탄핵을 요구하는 광화문 촛불집회 참 여자들을 대상으로 현장 설문을 통해 이루어졌다. 당시 박근혜-최순실 게 이트에서 드러난 권력의 사유화 및 최고 권력자들의 부패에 대해서 많은 시민들은 인터넷과 소셜미디어를 중심으로 비판 담론을 형성하였다. 나아 가 집회 현장에 대한 포스팅이나 집회 참여를 독려하는 게시글 등이 소셜 미디어를 통해 널리 공유되었는데, 이는 세계사적으로도 유례가 없는 시민 들의 자발적인 대규모 평화집회로 기록되었다. 이 연구에서는 소셜미디어 이용자들의 대화를 크게 ‘읽기’와 ‘쓰기’로 나누고, 읽기와 쓰기에 영향을 미치는 변수들을 살펴보았다. 또한 읽기와 쓰기가 실제 정치참여를 매개하 고 있는지 여부와 이용자의 인구통계학적 속성, 정치 인식, 주사용 소셜미 디어 서비스가 광화문 집회 참여에 어떤 영향을 미치는지를 분석하였다.

Objective: To compare 5-year disease-free survival (DFS) and overall survival (OS) rates oflaparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) forstage IB1 and tumor size <2 cm with visible or invisible tumors. Methods: We retrospectively compared the oncological outcomes of 1,484 cervical cancerpatients with IB1 and tumor size <2 cm on final pathology, who received ARH (n=899) or LRH(n=585) between January 2004 and December 2016. Patients were divided into visible tumorsubgroup (ARH: n=668, LRH: n=444) and invisible tumor subgroup (ARH: n=231, LRH:n=141) according to tumor type. Results: LRH and ARH showed similar 5-year DFS and OS rates (93.3% vs. 93.1%, p=0.997;96.2% vs. 97.5%, p=0.351) in total study population. LRH was not associated with worse5-year DFS rate (hazard ratio [HR]=0.96; 95% confidence interval [CI]=0.58–1.58; p=0.871)or OS rate (HR=1.37; 95% CI=0.65–2.89; p=0.409) by multivariable analysis. In the visibletumor subgroups, LRH and ARH showed similar 5-year DFS and OS rates (91.9% vs. 91.9%,p=0.933; 95.0% vs. 96.9%, p=0.276), and LRH was not associated with worse 5-year DFS orOS rate (p=0.804, p=0.324). In the invisible tumor subgroups, LRH and ARH also showedsimilar 5-year DFS and OS rates (97.3% vs. 97.1%, p=0.815; 100% vs. 99.5%, p=0.449), andLRH was not associated with worse 5-year DFS rate (p=0.723). Conclusions: Among patients with stage IB1 and tumor size <2 cm, whether the tumor isvisible or not, the oncological outcomes of LRH and ARH among cervical cancer patients arecomparable. This suggests that LRH may be suitable for stage IB1 and tumor size <2 cm withvisible or invisible tumors.Trial Registration: International Clinical Trials Registry Platform Identifier: CHiCTR180017778

Influence of chlorinated disinfection by-products on transmission of antibiotic resistance genes in biofilms and water of a simulated drinking water distribution system

Minglu Zhang,Lingyue Zhang,Kaizong Lin,Yue Wang,Shaofeng Xu,Miao Bai,Hairong Jiang,Shuangling Wang,Yongjing Wang,Can Zhang 대한환경공학회 2023 Environmental Engineering Research Vol.28 No.4

The spread of antibiotic resistance genes (ARGs) caused by biofilm growth in drinking water distribution systems (DWDSs) poses a serious threat to human health. The influence of disinfection by-products (DBPs) on the distribution of ARGs and mobile genetic elements (MGEs) in different phases (biofilms and water) of DWDSs is unclear. In this study, the characteristics of microbial indices, trihalomethanes (THMs), haloacetic acids (HAAs), ARGs and MGEs in biofilms and effluents of simulated DWDS reactors were detected during 150 d of operation. During the mature biofilm periods of 90 d or 120 d, for both biofilms and effluents, seven categories of ARGs (except tetracycline) and MGEs were at their highest and lowest relative abundance in the entire operation cycle, respectively. The influence of DBPs on ARGs and MGEs in the DWDS was different in different phases. In effluents, DBPs showed a stronger relationship with ARGs compared with MGEs. THMs and HAAs had positive correlations with various ARGs, which indicated that DBPs affected the distribution of resistance genes. In biofilms, the influence of MGEs on ARGs was stronger than that of DBPs on ARGs. Thus, DBPs might be an important contributor to the enrichment and spread of ARGs in water.
