왕긴 ( Wang¸ Qin ),김진성 ( Kim¸ Jin Sung ) 한국기초조형학회 2021 기초조형학연구 Vol.22 No.5

다기능 가구는 형태가 유연하고 공간을 절약할 수 있어 일상생활에서 비중이 꾸준히 늘고 있다. 하지만 미니멀리즘 디자인((minimalist design) 트렌드에 맞추기 위해 다기능 가구의 조형(modeling)에 담겨야 할 다양한 정보가 항상 무시되고 있다. 이 때문에 사용자들이 ‘심플한(simple)’ 조형에 직면할 경우 인식 마찰로 인해 사용상의 문제가 생길 수 있다. 이 연구의 목적은 사용자가 다기능 가구의 유용성(usefulness)과 편리함(usability)을 더 쉽게 감지할 수 있도록 하는 것이다. 저자들은 다기능 가구의 조형에 대해 어포던스(affordance)와 기표(signifier)의 관점에서 연구를 진행했다. 이 연구는 문헌 검토와 사례 분석을 서로 결합하는 방법을 응용하였다. 저자들은 우선 관련 문헌을 통해 기표와 어포던스 관계를 정리했다. 그런 다음, 이들은 다기능 가구의 사례별로 조형의 세 가지 핵심 요소(모양·색·재료)가 기능 전환 과정에서 어포던스를 지정하는 정보를 전달하는 지표의 역할을 분석했다. 마지막으로, 그들은 다기능 가구의 조형이 해당 어포던스를 명확하게 전달하는 풍부한 정보로 기표를 형성할 수 있다는 것을 발견했는데, 이는 사용자가 가구와 자연스러운 상호작용을 형성하도록 안내하는 데 도움이 된다. 또한, 그들은 다기능 가구 조형을 위해 다음과 같은 설계 단계를 제시했다. 1 단계: 다기능 가구의 기능은 대상 이용자(target user)의 요구에 근거하여 명확히 해야 하며, 사용자가 다른 기능 간에 전환하기 위해 수행해야 하는 동작도 결정해야 한다. 이 단계는 유용성을 실현하는 관건이다. 2 단계: 다기능 가구의 조형은 모양과 색상, 소재의 조합을 통해 구성하고 기능성(functionality)과 동작 가능성(action possibilities), 그에 맞는 동작의 조작 위치 등을 충분히 전달해야 한다. 이 단계가 사용 편의성을 실현하는 관건이다. 그러나 이 두 단계는 향후 연구에서 아직 더 심화돼야 한다. As multifunctional furniture has flexible forms and could save space, its proportion in daily life is constantly increasing. However, in order to cater to the minimalist design trend, the rich information that the modeling of multifunctional furniture should contain is always ignored, which causes users to have a series of usage problems because of cognitive friction when facing “simple” styling. In order to allow the usefulness and usability of multifunctional furniture to be easily perceived by users, the authors conducted a relevant study on the modeling of multifunctional furniture from the perspective of signifier and affordance. The research method of this study is a combination of literature review and case analysis. The authors first sorted out the relationship between signifier and affordance in industrial design through related literature. Then, the authors combined different cases of multifunctional furniture, to analyze the role of the three core elements(shape, color and material) of the modeling as signifiers that carry information specifying affordances during the functional transformation. Finally, the authors found that the modeling of multifunctional furniture can form signifiers with rich information that clearly conveys the corresponding affordances, which is helpful to guide users to form natural interactions with multifunctional furniture. And the authors also put forward the following design steps for multifunctional furniture modeling. Step 1: the functions of multifunctional furniture should be clarified based on the needs of target users, and the actions that users need to perform to switch between different functions should also be determined. The first step is the key to realizing usefulness. Step 2: the modeling of multifunctional furniture should be constructed through different combinations of shapes, colors and materials, which should fully convey the information of the functionality, action possibilities and the operating positions of the corresponding actions. The second step is the key to realizing ease of use. However, these two steps still need to be further deepened in future studies.

Zhuoping Qin(Zhuoping Qin),Xu Jin(Xu Jin) The International Academy of Global Business and T 2022 The International Academy of Global Business and T Vol.18 No.5

Purpose - This is a study on the influence mechanism of rural finance and rural industrial revitalization on rural logistics development from rural revitalization strategy. Design/Methodology/Approach - We use panel data of 30 Chinese provinces from 2011 to 2020. A two-way fixed-effects model is constructed and mediated effects analysis and multiple regression analysis are used to analyze the dynamic relationship between rural finance, rural industrial revitalization, and rural logistics development. The dynamic relationship was empirically analyzed using mediated effects analysis and multiple regression analysis. Findings - Rural finance has a significant positive impact on rural logistics, and rural finance effectively promotes rural logistics development; rural finance affects rural logistics development by influencing the revitalization of rural industries, indicating that the revitalization of rural industries plays a mediating effect. The impact of rural finance on rural logistics is heterogeneous in the east, central, and west. Rural industry revitalization does not play a mediating role in the central era, comparing with an obvious mediating role in the east and west. Research Implications - The revitalization of rural industries as a transmission mechanism for rural finance to promote the development of rural logistics, and we verify the rationality of this transmission mechanism through a model to fill the gaps in the existing literature, thus providing a new research perspective for rural finance to promote the development of rural logistics, and providing some theoretical guidance and policy reference.

Bacillus thuringiensis 1-3 (Bt 1-3), belonging to subsp. aizawai (H7), showed different characteristics in plasmid profiles from type strain and had cry2A gene in addition to cry1Aa, cry1Ab, cry1C and cry1D. To clone its plasmids and construct E.coli-Bt shuttle vector, we constructed the plasmid capture system (PCS) by inserting attB sites including lacZ between transposable elements (designated as pPCS-Troy). Through in vitro transposition with total plasmids DNA of Bt 1-3, 53 clones were acquired and their sizes were approximately 10 kb. Based on the sequence analysis, they were classified in four groups showing similarities with four known Bt plasmids, pGI3, pBMB175, pGI1 and pGI2, respectively. One of pGI3-like clones, named as pBt1-3, was fully sequenced and its putative open reading frames (ORFs), Rep-protein, double-strand origin of replication (dso), single-strand origin of replication (sso), have been identified. The structure of pBt1-3 showed high similarity with pGI3 which is one of rolling-circle replication (RCR) group VI family. As a donor for construction of shuttle vector, pDonr-attPEm vector harboring erythromycin resistant gene between attP sites was constructed. Through BP recombination with pPCS-Troy-cloned Bt plasmids and pDonr-attPEm, erythromycin resistant gene was transposed to Bt plasmids. This scheme proposes that in vitro transposition using pPCS-Troy and BP recombination using pDonr-attPEm can easily clone Bt plasmids and construct novel shuttle vectors.

A 3-D Steady-State Analysis of Thermal Behavior in EHV GIS Busbar

Jin Lei,Jian-ying Zhong,Shi-jin Wu,Zhen Wang,Yu-jing Guo,Xin-yan Qin 대한전기학회 2016 Journal of Electrical Engineering & Technology Vol.11 No.3

Busbar has been used as electric conductor within extra high voltage (EHV) gas insulated switchgear (GIS), which makes EHV GIS higher security, smaller size and lower cost. However, the main fault of GIS is overheating of busbar connection parts, circuit breaker and isolating switch contact parts, which has been already restricting development of GIS to a large extent. In this study, a coupled magneto-flow-thermal analysis is used to investigate the thermal properties of GIS busbar in steady-state. A three-dimensional (3-D) finite element model (FEM) is built to calculate multiphysics fields including electromagnetic field, flow field and thermal field in steady-state. The influences of current on the magnetic flux density, flow velocity and heat distribution has been investigated. Temperature differences of inner wall and outer wall are investigated for busbar tank and conducting rod. Considering the end effect in the busbar, temperature rise difference is compared between end sections and the middle section. In order to obtain better heat dissipation effect, diameters of conductor and tank are optimized based on temperature rise simulation results. Temperature rise tests have been done to validate the 3-D simulation model, which is observed a good correlation with the simulation results. This study provides technical support for optimized structure of the EHV GIS busbar.

Construction of novel Escherichia coli-Bacillus thuringiensis shuttle vector using amodified plasmid capture system

Qin Liu,Jong Yul Roh,Yong Wang,Hee Jin Shim,Jae Young Choi,Hong Guang Xu,Byung Rae Jin,Yeon Ho Je 한국응용곤충학회 2008 한국응용곤충학회 학술대회논문집 Vol.2008 No.10

Bacillus thuringiensis 1-3 (Bt 1-3), isolated from Korean soil sample, showed high insecticidal activity against Plutella xylostella. Recently, we improved plasmid capture system donor-s (PCS-S) by inserting attB sites including lacZ between transposable elements (designated as pTroy), to reduce background and construct E. coli-Bt shuttle vector. Through in vitro transposition with total plasmid DNA of Bt 1-3, at least 6 different size plasmids of Bt 1-3 were cloned. Among them, 47 clones which have approximately 10 kb plasmid in size were sequenced and 5 contigs were assembled. These contigs showed partial similarity with two known plasmids, pGI3 or pBMB175, separately. These cloned plasmids will acquire erythromycin resistance by BP recombination reaction with pDonrattPEm vector. After transformation into Bt cells, final erythromycin resistant Bt cell might contain novel E. coli-Bt shuttle vector. This scheme proposes that pTroy and pDonr-attPEm system can easily construct new shuttle vector by in vitro transposition, BP reaction, and erythromycin selection with any Bt plasmids.

Characterization of insecticidal Bacillus thuringiensis 1-3 strain and destruction of its sigG gene by homologous recombination

Qin Liu,Jong Yul Roh,Yong Wang,Hee Jin Shim,Jae Young Choi,Hong Guang Xu,Byung Rae Jin,Yeon Ho Je 한국응용곤충학회 2008 한국응용곤충학회 학술대회논문집 Vol.2008 No.05

A strain of Bacillus thuringiensis, named Bt 1-3, was isolated from Korean soil sample and it showed high insecticidal activity against Plutella xylostella. Bt 1-3 was deterimined to belong to ssp. aizawai (H7) by an H antiserum agglutination test and produced bipyramidal-shaped crystal proteins. PCR analysis with specific cry gene primers showed that Bt 1-3 contained cry1Aa, cry1Ab, cry1C, cry1D and cry2Ab genes. In addition, this isolate showed high uptake rate of foreign plasmid by electroporation. Based on these characteristics of Bt 1-3, we tried to construct a spore-free Bt 1-3 mutant by knock-out sigG gene, which is known as a key transcription factor during sporulation. First, we constructed a basal vector, named pDST, consisting of erythromycin resistant gene (EmR), partial polyhedrin gene and temperature sensitive origin of replication gene (Orits). Subsequently, according to the chromosomal DNA sequence of Bt subsp. konkukian 97-27, we amplifed upstream and downstream regions of Bt 1-3 sigG, and cloned into pDST (pDST-G). So far, several EmR colonies were obtained by electroporating into the wildtype Bt 1-3 and crossover by homologous recombination is going on.

Bacillus thuringiensis 1-3 (Bt 1-3), belonging to subsp. aizawai (H7), showed different characteristics in plasmid profiles and had cry2A gene in addition to cry1Aa, cry1Ab, cry1C and cry1D. This strain exhibited dual insecticidal activity against Aedes aegypti as well as Plutella xylostella. Recently, we improved the donor-s of plasmid capture system (PCS) by inserting attB sites including lacZ between transposable elements (designated as pPCS-Troy), to construct E.coli-Bt shuttle vector.

As a donor for construction of shuttle vector, pDonr-attPEm vector harboring erythromycin resistant gene between attP sites was constructed. Through BP recombination with pPCS-Troy-cloned Bt plasmids and pDonr-attPEm, erythromycin resistant gene was transposed to Bt plasmids. This scheme proposes that in vitro transposition using pPCS-Troy and BP recombination using pDonr-attPEm can easily construct novel shuttle vectors with any Bt plasmids and this combined procedure can introduce foreign gengs into various circular DNA molecular.
