LILI,이종윤,ShanShan LIU,홍장선 국제문화기술진흥원 2023 International Journal of Advanced Culture Technolo Vol.11 No.2

Modern people live a life connected with the real world and the virtual world by relying on the new media of enterprises and social consumption led by innovative technologies. In this environment, virtual influencers actively communicate with consumers and build relationships through social media, which is a new marketing tool that has attracted widespread attention. From a business perspective, it is necessary to have a solid understanding of this phenomenon, and then explore communication strategies to effectively develop virtual influencers. To investigate followers' preference for virtual influencers, this study employs the Q-method, which studies human subjective attributes, an empirical research effort to uncover complex issues in human subjectivity. To determine the factors that trigger people's voluntary and active practice and the preference degree of virtual influencers, the Q method is implemented to examine human subjectivity, thoughts and attitudes. According to the results of this study, virtual influencers are a new group of idols full of vitality. The interviews found that there are still many virtual influencers who do not know about followers, but each type can be clearly understood through the intuitive understanding of the interviewees. Divided out, type 1 one ego-ideal virtual influencers aim to represent an idealized version of the creator or target audience. Embodies ideal physical characteristics, personality or lifestyle desired by the audience. Type 2 is charismatic and attractive, and has the characteristics of most virtual influencers. It is suggested that it can be developed into a potential type, doing brand cooperation, and content production on social media platforms. Type 3: Game animation, derived from the image of characters in games or comics, with stylized features and energetic personalities, which can be integrated into games or entertainment experiences. Type 4 development potential type is the most successful type among virtual imagers, and it is also the purpose of marketing virtual influencers. It is essential that brand endorsement on social media platforms, integrated marketing, and driving advertising traffic. It is recommended to improve production technology to reduce investment costs.

An Explanation of Waiting for Godot in Quantum Mechanics

LiLi 동국대학교 영어권문화연구소 2020 영어권문화연구 Vol.13 No.2

On Samuel Beckett's Waiting for Godot, everyone explains the existence of Godot differently, which makes the superposition of Godot. And from the point of view of quantum mechanics, microscopic particles may be in a superposition state, which means things are always in an uncertain state of “superposition” or “collapse” according to the human consciousness. After introducing the concept of quantum mechanics, the paper uses the Schrodinger's cat, a famous experiment of quantum mechanics, to conduct in-depth exploration. In the experiment, cats exist in closed boxes, and no one knows whether they have changed or if they have had quantitative changes. No one knows what's going to happen before the box is opened, and it is uncertain whether there will be changes when the box is opened. The uncertainty of quantum mechanics affects people's thinking. Hence the paper attempts to explore Beckett's Waiting for Godot for the uncertainty of the entanglement waiting process by quantum mechanics by analyzing Godot as a stacked-up cat.

20세기 이래 중국 상고음(上古音) 연구의 성과 및 방향

張莉莉 ( Zhang¸ Lili ) 한국중국언어학회 2021 중국언어연구 Vol.- No.95

이 글의 목표는 20세기 초부터 지금까지의 중국 上古音에 대한 연구 성과, 특히 최근에 나온 연구에 주목하여 정리하고, 上古音 연구 동향을 파악하기 위한 것이다. 이를 위해 약 백 년 동안의 연구사를 간략하게 살펴본 후, 上古音 연구에 있어서 논쟁거리인 음절 유형, 운미, 모음체계, 介音의 존재 여부, 기본 자음체계, 복자음체계, 그리고 관련된 형태 연구를 중심으로 살펴보았다. 최근 주류 입장에 따르면 上古漢語의 陰聲 운미에는 유성 폐쇄운미가 없었고 개음절을 지니며, 또한 성조가 없었고, 후치운미가 중고시기에 성조를 이루게 된다. 모음체계의 경우 대략 ‘i, Щ, u, e, a, o’와 같이 6개 모음으로 이루어진 것으로 볼 수 있으며, 上古漢語에는 모음성 介音이 존재하지 않고 介音 /r/가 많은 역할을 했다. 한편, 기본 자음 체계에서 논의된 來母와 喉音 계열 및 무성 비음과 무성 유음에 대한 관점은 최신 이론에서 큰 차이를 보이지 않지만, 精母 파찰화 등에 관하여는 아직 異論이 존재하며, 자음군의 경우는 대개 전치자음과 후치자음을 통하여 복자음 체계를 해석하고 있다. 또한, 上古漢語의 재구에 있어서 형태의 기능과 음운 형식에의 대응 관계가 최근의 연구에서 관심을 받고 있다. 마지막으로 上古音의 연구 방법, 연구 자료, 연구 범위를 살펴봄으로써 앞으로의 연구 방향을 제시하여 보았다. The goal of this article is to focus on the achievements of Old Chinese from the early 20^th century till the present, especially from current studies and controversial views to identify trends in Old Chinese studies. In this paper, it presented a brief look at the research history of Old Chinese about 100 years, and focused on the study of syllable types, codas, vowel systems, an existence of the medial, simple initials, initial clusters, and related morphological forms. According to the recent mainstream opinions, Old Chinese yīnshēng rhyme group did not have voiced stop, neither the intonation in Old Chinese, while postcodas became intonations in Middle Chinese. In the case of vowel systems, it can be considered to be consist of the six vowels, such as ‘i, Щ, u, e, a, o’, and there was no vocal medial but /-r-/, which played a major role as medial in Old Chinese. The perspectives of initial /r/, uvular initials, voiceless resonants do not differ much in recent research, however, views about the reconstruction of (MC.)/ts/ in Old Chinese, and whether it was an affricative initial are quite different. The system of initial clusters were mainly consist of pre-initial and post-initial. Furthermore, the function of morphological forms and its correspondence to phonetic forms have drawn attention in recent research. Finally, it presented future research directions through looking at the research methods, materials, and scope of the study in Old Chinese.

Polymeric nanocarrier systems for photodynamic therapy

Li Li,허강무 한국생체재료학회 2015 생체재료학회지 Vol.19 No.1

Photodynamic therapy (PDT) is an emerging treatment modality that involves the combined action of photosensitizers (PSs) and light for treatment of solid tumor and other diseases. Although this therapeutic method has been considered as an alternative to classical cancer treatments, clinical PDT requires further advances in selectivity and therapeutic efficacy to overcome numerous shortages related to conventional PDT. In this regard, great efforts have been devoted to the development of polymeric nanocarrier-encapsulated PSs for targeted PDT, aiming at improvement of water solubility and tumor-specificity of hydrophobic PSs. Here, we discuss the general concepts and considerations of polymeric nanocarriers for efficient delivery of PSs. In recent, the amphiphilic PS-polymer conjugate-based self-quenchable nanoparticles and PS-polymer-conjugate/quencher nanocomplexes have emerged as an attractive delivery platform for efficient and reliable PDT. They can incorporate and deliver the PS in a photodynamically inactive state but demonstrate cytotoxic effects by tumor environment-sensitive activation mechanisms, so that the photodynamic cancer treatment can achieve maximum target specificity. Here, we report the recent achievements on the development of activatable PS formulations based on PS-polymer conjugates.

Li, Li,Nie, Yu,Zhu, Rong,Shi, Sanjun,Luo, Kui,He, Bin,Yang, Yang,Yang, Junxiao,Gu, Zhongwei 대한약학회 2008 Archives of Pharmacal Research Vol.31 No.7

Cationic lipids 1, 2, and 3, based on hydrophobic cholesterol linked to L-lysine, L-histidine or Larginine, respectively, were designed and tested as gene delivery vectors. Physicochemical and biological properties of all liposomes and lipoplexes were evaluated, including lipid-DNA interactions, size, morphology, zeta potential, acid-base buffering capability, protection of DNA from DNase I digestion, and cytotoxity. The efficiency of luciferase gene transfection of lipoplexes 1-3 was compared with that of commercial dioleoyl-trimethylammonium propane (DOTAP) and polyethyleneimine (PEI) in 293T cells and HepG2 cells with or without poly(ethylene glycol) PEG stabilizer. The complexation and protection of DNA of liposome 3 was the strongest among the three liposomes. The efficiency of gene transfection of liposomes 1-3 was two-to threefold higher than that of PEI and/or DOTAP in 293T cells. Liposomes 1 and 3 in PEG as stabilizer showed sixfold higher transfection efficiency than that of PEI and/or DOTAP, whereas liposome 2 showed very low transfection efficiency. In HepG2 cells, the transfection efficiency of all the cationic liposomes was much lower than that of DOTAP. In conclusion, lipids 1-3 were efficient and non-toxic gene vectors; the headgroup of cationic lipids and the stabilizer of liposome formulation had an important influence on gene transfection.

Growth of Ni/Co-Catalyzed Crystalline CNx Thin Films by Nitrogen-Plasma-Assisted Pulsed Laser Deposition

Li Li,Ning Xu,Aimin Wu,Hao Ling,Jian Sun,Xiaokang Shen 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.1

Nanocrystalline carbon nitride (CNx) thin ¯lms have been synthesized by nitrogen-plasma-assisted pulsed-laser deposition. Before depositing carbon nitride ¯lm, Ni/Co was deposited on the silicon (100) substrate acting as catalyst. The properties of the deposited ¯lms were studied by several diagnostic techniques. X-ray photoelectron spectroscopy was used for detecting the compo-sition ratio N/C in the ¯lm. From studying Raman spectra under dierent conditions we can ¯nd how glow discharge pressure aects the carbon nitride ¯lm properties. Two stages in this process and nanocrystallites of tens of nanometers embedded in the as-synthesized thin ¯lm can be seen by transmission-electron microscopy. The FTIR spectrum suggests an abundance of C-N bonds and paucity of C´N bonds, which is a favorable chance for the formation of carbon nitride crystallites. The crystalline nature of the ¯lm is detected by X-ray diraction.

Cloning and Functional Analysis of the Gβ Gene Mgb1 and the GγGene Mgg1 in Monascus ruber

Li Li,Lu He,Yong Lai,Yanchun Shao,Fusheng Chen 한국미생물학회 2014 The journal of microbiology Vol.52 No.1

The ascomycetous fungus Monascus ruber is one of the most well-known species widely used to produce Monascus-fermentation products for natural food colorants and medicine. Our previous research on the Gα subunit Mga1 and the regulator of G protein signaling MrflbA indicated that heterotrimeric G protein signaling pathways were involved in aspects of growth, sporulation and secondary metabolite production in M. ruber. To better understand the G protein signaling pathways in this fungus, a Gβ subunit gene (Mgb1)and a Gγ subunit gene (Mgg1) were cloned and investigated in the current study. The predicted Mgb1 protein consisted of 353 amino acids and Mgg1 consisted of 94 amino acids,sharing marked similarity with Aspergillus Gβ and Gγ subunits,respectively. Targeted deletion (Δ) of Mgb1 or Mgg1resulted in phenotypic alterations similar to those resulting from ΔMga1, i.e., restricted vegetative growth, lowered asexual sporulation, impaired cleistothecial formation, and enhanced citrinin and pigment production. Moreover, deletion of Mgg1suppressed the defects in asexual development and in biosynthesis of citrinin and pigment caused by the absence of MrflbA function. These results provide evidence that Mgb1and Mgg1 form a functional Gβγ dimer and the dimer interacts with Mga1 to mediate signaling pathways, which are negatively controlled by MrflbA, for growth, reproduction and citrinin and pigment biosynthesis in M. ruber.

The Direct Adaptive Control Based on the Singularly Perturbed Model with the Unknown Consequence Parameters

Li Li,Fuchun Sun 제어·로봇·시스템학회 2010 International Journal of Control, Automation, and Vol.8 No.2

A class of nonlinear singularly perturbed systems can be approximated by the Fuzzy Singularly Perturbed Model (FSPM).This paper proposes a new direct adaptive controller on the basis of the FSPM. The aim is to make the states of the closed-loop system follow those of the reference model. The feedback gains of the controller can be adjusted on line; and we don’t require the parameters known in prior. Lyapunov constitute techniques are used to prove the stability of the closed loop sys-tems. Finally the simulations illustrate the effectiveness of this approach.
