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.

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.

司马相如品行新说

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.

한국어 합성어에서의 경음화 습득 양상 연구 -중국인 학습자를 중심으로-

부가준 ( Fu Jia-jun ),배영환 ( Bae Young-hwan ) 국제어문학회(구 국제어문학연구회) 2020 국제어문 Vol.0 No.84

본 연구는 중국인 학습자를 대상으로 한국어의 합성어에서 나타나는 경음화의 실현 양상을 살펴보고, 이를 바탕으로 효과적인 발음 교육 방안을 논의하는 데 목적이 있다. 합성어에서의 경음화는 일반적인 장애음 뒤 경음화와 공명음 뒤경음화와는 달리 매우 불규칙적이다. 때문에 외국인 학습자들이 합성어에서의 경음화를 학습하는 데에 어려움이 있다. 합성어에서의 경음화 현상은 비음운론적 정보가 필요한데, 먼저 특정 형태소에서 실현되는 경음화와 의미 관계에 따라 실현되는 경음화로 나눌 수 있다. 특정 형태소에서 실현되는 경음화는 사이시옷을 항상 동반하는 ㅅ-전치형 형태소와 ㅅ-후치형 형태소가 있다. 의미 관계에 따른 경음화는 합성어의 앞 요소가 뒤 요소의 ‘시간, 장소, 용도, 기원이나 소유주’ 등으로 구분할 수 있다. 그러므로 합성어에서의 경음화를 외국인 학습자들에게 교수할 때는 비음운론적인 정보를 효과적으로 이용할 필요가 있다. 이를 위해 본고는 중국 현지에서 한국어를 학습하고 있는 학생을 대상으로 합성어에서의 경음화의 실현 양상을 살펴보았다. 먼저, 교재 분석과 선행 연구를 바탕으로 조사 목록 83개를 선정하였다. 추출된 어휘 목록을 대상으로 초·중·고급 중국인 한국어 학습자 34명을 대상으로 발음 조사를 실시하였다. 조사 결과, 합성어에서의 경음화 실현율은 59%에 불과했다. 다만 고급 단계의 학습자는 상대적으로 실현율이 높았다. 아울러, 경음화를 과도하게 적용하는 경우도 높은 비율로 나타났는데, 이는 ‘유추’에 따른 오류로 판단된다. 이에 따라 합성어에서의 경음화에 대해 두 가지로 나누어 학습 방안을 제시하였다. 특정한 형태소에서 나타나는 경음화는 청각 구두 교수법에 따라 수업을 진행하고, 의미 관계에 의한 합성어 경음화는 두 구성 요소의 의미 관계를 중국어와 대조하면서 그 특성과 유사점을 살리며 학습 방법을 제시하였다. This study examines the realization of phonograms in Korean compound words and discusses effective pronunciation education methods for Chinese learners. Unlike the fortis behind obstruent or sonorant, the phonological fluctuation principles and pronunciation rules of compound phonation are complicated and irregular, based on various realization environments, thus making it difficult for foreign learners to learn Korean. Korean phenomena are divided into five types and the characteristics of the phenomena in Korean compound words are examined. The phenomena in compound words require non-phonological information, which can be divided into fortis realized in specific morphemes and fortis realized according to semantic relations. There are two types of fortis that are realized in certain morphemes: the S-prepositional morphology and the S-postpositional morphology, which are always accompanied by saisiot. In phonation based on the semantic relationship, the front element of the compound word can be categorized into time, place, use, origin, or owner of the back element. Therefore, it can be said that non-phonological information is required when teaching phonology in compound words to foreign learners. In addition, this study examined the realization of phonation in compound words for students studying Korean in China. For this purpose, 83 survey lists were selected based on textbook analysis and literature review. A survey regarding pronunciation was conducted on 34 Korean learners in elementary, middle, and high grades. The study results show that the realization rate of the fortis in the compound word was only 59%, and many errors were noted. However, the higher-level learners had a relatively high rate of realization. Furthermore, excessive application of fortis was noted to be a high rate. In these errors, words with high independence showed high errors. Therefore, two types of phonation in compound words are presented in a specific morpheme. Synthetic verbalization by semantic relations led to the suggestion of a learning method by comparing the semantic relations of the two components with the Chinese language and utilizing its characteristics and similarities.

Jian Jun Fu,Hui Zi Jin,Jiang Jiang Qin,Qi Zeng,Ying Huang,Wei Dong Zhang 대한약학회 2011 Archives of Pharmacal Research Vol.34 No.2

Two new monoterpene alkaloid derivatives, incargutosines C (1) and D (2), together with a known compound, argutine A (3) have been isolated from the roots of Incarvillea arguta Royle. The structures of 1 and 2 were established on the basis of 1D and 2D NMR spectroscopic analysis, while the absolute configurations of 1 and 2 were determined by a synthetic method. In addition, the cytotoxicity of 3 was evaluated using four tumor cell lines, A549, LOVO, 6TCEM, and MDA-MB-435 (MDA) by the MTT assay.

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.
