Ultrastructural observations of Beauveria bassiana infection in Xylotrechus rusticus larvae

Jun‐Nan Ding,De-Fu CHI 한국곤충학회 2018 Entomological Research Vol.48 No.3

In the present study we investigated the infection process of Beauveria bassiana on Xylotrechus rusticus larvae using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The SEM results showed that B. bassiana spores germinated on the surface of the larval body and invaded the larva as an appressorium. The hyphae then germinated from the spores and spread throughout the larval body. After the death of the larva, conidiophores formed at one end of the hypha on the surface of the larval body and prepared for a new round of infection. The TEM results showed severe damage to the larval cuticle after hyphae infection. The structure of the cuticle became thinner and eventually flocculent; muscle tissues were dissociated and eventually stuck to the hyphae, and the corpus adiposum was loose and deformed, and eventually degraded.

서한 양웅으로부터 시작하여 사마상여에 대한 평론은 중단된 적이 없었다. 평가의 초점은 “買官”, “竊色”, “劫財” 등 부분에 맞춰있다. 한초 문경시기 “자選”이라는 선관제도를 실행하였는데 사마상여의 “재물로 낭관이 되었다”는 기록은 바로 이러한 나라에서 법률로 정한 방식으로 획득한 것이므로 합법적인 것이지 매관의 문제가 존재하는 것은 아니다. 사마상여와 탁문군이 성도로 도주를 했다는 일도 당시 과부를 취할 때 “협의하여 강제 혼인을 한다”는 방식을 이용했을 뿐이지 역시 겁탈 따위의 문제가 되는 것이 아니다. 사마상여와 탁문군이 탁왕손으로부터 거액의 재산을 얻게 된 일도 대부분 당시 법률상 탁문군이 당연히 획득하게 될 내용이지 재산을 탈취했다는 문제는 존재하지 않는 것이다.

An Efficient Synthesis of Substituted Furans by Cupric Halide-Mediated Intramolecular Halocyclization of 2-(1-Alkynyl)-2-alken-1-ones

Fu, Wei-Jun,Xu, Feng-Juan,Guo, Wen-Bo,Zhu, Mei,Xu, Chen Korean Chemical Society 2013 Bulletin of the Korean Chemical Society Vol.34 No.3

An efficient synthesis of 3-halofurans by the intramolecular cyclization of 2-(1-alkynyl)-2-alken-1-ones with cupric halide has been developed. A broad range of 3-chloro- and 3-bromofuran derivatives could be obtained in the present method in moderate to good yields. The 3-halofuran derivatives are potential synthetic intermediates for amplification of molecular complexity.

An integrated bioinformatics analysis of mouse testis protein profiles with new understanding

( Fu Jun Liu ),( Hai Yan Wang ),( Jian Yuan Li ) 생화학분자생물학회(구 한국생화학분자생물학회) 2011 BMB Reports Vol.44 No.5

The testis is major male gonad responsible for spermatogenesis and steroidogenesis. Much knowledge is still remained to be learned about the control of these events. In this study, we performed a comprehensive bioinformatics analysis on 1,196 mouse testis proteins screened from public protein database. Integrated function and pathway analysis were performed through Database for Annotation, Visualization and Integrated Discovery (DAVID) and ingenuity Pathway Analysis (IPA), and significant features were clustered. Protein membrane organization and gene density on chromosomes were analyzed and discussed. The enriched bioinformatics analysis could provide clues and basis to the development of diagnostic markers and therapeutic targets for infertility and male contraception.

서학동점(西學東漸)과 중국현대 학술의 생성

부영군(Fu yong-jun) 영남대학교 민족문화연구소 2020 민족문화논총 Vol.74 No.-

Since Western studies was introduced to China, the traditional form of Chinese studies has declined. At the moment, Chinese studies also have entered the Post classical learning era(后经学时代) from the classical learning era(经学时代). The disintegration of the traditional China concept led to the transition of Chinese scholars from tradition to modern times. Since the concept of nation state replaced the concept of the Chinese Empire, and also the concept of the “world” replaced the concept of the “Tian-xia(天下)”, different peoples, different political and cultural communities have formed a coexistence relationship in pure spatial meaning. In addition, the political and cultural significance of the single concept of China has been greatly weakened, and the spatial regulation in the geographical sense has lost meaning. Thus, politics and academia were combined, and traditional Chinese studies, which centered on classical learning, lost the social and historical conditions of its existence. The abolition of the tradition of religion and politics caused the loss of the exclusive status of the classical learning in the traditional Chinese academic system. On the surface, the transition from Chinese academic tradition to modernity was the result of the Eastward transmission of Western sciences(西学东渐). However, it was only one occasion, in fact, the factor of this change came from the Chinese traditional academic itself. In short, the distinction between East and West caused the debate between ancient times and the present, and furthermore, It was also derived from it. As a result, The classical learning has collapsed, and The study of One hundred schools has emerged, which is combined with Western studies, Eventually it formed a new knowledge base in China. From this, discussing China s modern studies must involve a Western perspective, whether it is interpreting Western influences or returning to the subjectivity of Chinese academia and distinguishing it from Western studies, a prior understanding structure that can never be ignored. Only under this perspective, we can understand differences in the same, identify differences in the same, and finally, beyond such sameness and differences, we can pursue a quest for the fundamental problems of universal learning, and the Modern Chinese studies can also move away from the level of local knowledge and head to the world. 서학(西學)이 동쪽에 전파된 이래, 중국학술의 전통 형태는 종결되었고, 중국학술은 경학시대로부터 “후경학시대(後經學時代)”에 진입하였다. 전통적 “중국” 개념의 해체는 중국 학술이 전통으로부터 현대에 이르는 전환 과정을 열었다. 민족국가 관념이 중화제국 관념을 대체하고, 세계 개념이 천하 개념을 대체한 이후, 다른 민족, 다른 정치문화 공동체는 순수한 공간적 의미상에서의 병존관계를 구성하였으며, “중국”의 정치 의의와 문화 의의는 대대적으로 감소하였고, 지리적 경계 의미상에서의 공간 규정은 의미를 상실하게 되었다. 이 때문에, 정치, 학술이 결합하였고, 경학을 주체로 삼는 중국 전통학술은 그 존재의 사회적, 역사적 조건을 잃어버렸다. 정교(政教) 전통의 폐지는 곧 직접적으로 경학의 중국전통 학술체계 가운데에서의 독존적 지위의 상실을 야기하였으니, 꽃은 이미 흐드러졌고 영광은 영멸하였다. 표면적으로 보면, 중국 학술의 전통으로부터 현대에 이르는 전환은 서학동점의 결과였다.그러나 변혁의 실질적 추동 요인은 중국 전통 학술 내부로부터 기인한 것이다. 서학동점은 그저 하나의 계기에 불과했는데, “중서지별(中西之別)”이 “고금지변(古今之辨)”을 야기하였으며, 나아가 “고금지변(古今之變)”으로 파생되었다. 그 결과는 “경학(經學)”의 와해, “자학(子學)”의 돌출, 서학과의 상호 결합으로 표현되었으며, 중국의 새로운 지식계보를 구성하였다. 이로부터 볼 수 있듯, 중국의 현대학술을 토론하는 것은 서양의 관점을 벗어날 수 없으며, 서양의 영향을 해석하는 것이든, 아니면 중국 학술의 주체성으로 회귀하여 서학과 소원해지고자 것이든 막론하고, 서학동점은 결코 배척할 수 없는 “전이해(前理解)구조”이다. 오로지 이러한 관점 하에서만 비로소 같음 가운데 다름을 변별하고, 다름 속에서 같음을 볼 수 있을 것이며, 아울러 최종적으로는 그러한 이동(異同)을 초월하여, 보편적 학술의 근본 문제에 대한 탐구로 향하는 도경을 열 수 있을 것이며, 중국 현대학술 또한 비로소 진정으로 지역적 지식으로부터 세계로 나아갈 수 있을 것이다.

Prescribed-time Stabilization for a Class of Nonlinear Systems with Control Singularities

Lulu Fu,Ruicheng Ma,Jun Fu 제어·로봇·시스템학회 2023 International Journal of Control, Automation, and Vol.21 No.2

This paper studies the prescribed-time stabilization of a class of nonlinear systems with control singularities. The settling time is independent of not only the design parameters but also the initial conditions, and can be set according to per our will. By using backstepping, we simultaneously construct a control Lyapunov function (CLF) with singularity and a control law to prescribed-time stabilize the equilibrium point of the studied system in settling time, and avoid all trajectories from crossing the control singularity set. Further, the feasibility region is consistent with the attraction region, and the attraction region is also maximized. That is, the positive invariance condition is achieved. Finally, two examples are presented to illustrate the effectiveness of our proposed method.
