Fiduciary Duty of Controlling Shareholders to Creditors : A Dual Perspective of Legislation Theory and Explanation Theory Based on Article 20 of China’s Company Law

Xia Si Yu,Cao Xing Quan 원광대학교 한중관계연구원 2023 韓中關係硏究 Vol.9 No.1

지배주주가 소수 주주에 대한 신의의무와 이사가 채권자에 대한 신의의무는 어느 정도에 지배주주와 채권자 간의 긴장 관계를 완화시켰지만 근본적으로 양자 간의 이익 불균형 상태를 교정할 수 없다. 중국 회사법의 언어 환경에서 신의의무 이론과 성실신 용 원칙은 공동으로 지배주주가 채권자에게 신의의무를 부담해야 하는 데 법리적 기초 를 제공했다. 하지만 특수한 상황에서 적용할 수 있는 법인인격부인제도는 채권자에게 지배주주와 같은 권리남용 행위에 대한 일반적인 구제를 제공하지 못하고 채권자는 회사법상 일반적인 보호의 부족에 직면했다. 본고는 지배주주가 채권자에 대한 신의의 의무가 무엇인지에 대한 질문에 답하는 대신 중국회사법 제20조에 대한 해석론적 시각에 대한 분석을 바탕으로 중국 회사법 입법론상의 보완 방법을 제시한다. 중국회사법 개정은 한편으로 지배주주가 채권자 및 회사, 기타 주주에 대한 신의의 의무를 정면으로 확립하고 회사관리의 양성상호작 용을 형성하여 지배주주의 행위에 적절한 인도를 제공할 수 있다. 다른 한편으로 채권 자에게 지배주주의 특별위신책임 이외의 일반위신행위에 대한 구제경로를 제공하고 지배주주의 채권자에 대한 일반위신책임조항을 증설해야 한다. 마지막으로, “민법전” 과 “중화인민공화국 민법전” 총칙편의 적용에 관한 최고인민법원의 몇 가지 문제에 관한 해석 “규정에 응답하는 기초에서, 또한 주주가 권리를 남용하여 회사, 기타 주주 또는 채권자의 이익에 손해를 끼치는 결의는 무효를 확인하여 신의의 의무의 구제 범 위와 구제 유형을 확대해야 한다는 것을 더 명확히 할 수 있다. Although the fiduciary duty of controlling shareholders to minority shareholders and directors to creditors have eased the tension between controlling shareholders and creditors to a certain extent, they cannot fundamentally correct the imbalance of interests between them. In the context of China’s Company Law, the theory of fiduciary duty and the principle of good faith jointly provide the legal basis for the controlling shareholders to assume fiduciary duty to creditors, However, the system of denial of corporate personality, which can only be applied under special circumstances, cannot provide creditors with conventional remedies against the general abuse of rights by controlling shareholders. Creditors are faced with inadequate general protection by China’s Company Law. This article does not attempt to answer the question of what is the fiduciary duty of the controlling shareholder to the creditor, but based on the analysis of the explanation theory perspective of Article 20 of China’s Company Law, puts forward the improvement path of the legislation theory of China’s Company Law. On the one hand, the revised Company Law of China can positively establish the fiduciary duty of controlling shareholders to creditors, the company and other shareholders, form a benign interaction of corporate governance, and provide appropriate guidance for the behaviors of the controlling shareholders. On the other hand, it is also necessary to provide the creditor with a remedy for general breaches of trust other than special breaches of trust by controlling shareholders, and to add provisions for general breaches of trust by controlling shareholders to creditors. Finally, in response to the provisions of the Civil Code and the Interpretation by the Supreme People’s Court of Several Issues Concerning the Application of Book One General Provisions of the Civil Code of the People’s Republic of China, the revised Company Law of china may also further explicitly stipulate that resolutions of shareholders by abusing their rights and damaging the interests of the company, other shareholders or creditors should be ruled as invalid, so as to expand the scope and types of remedies for fiduciary duty.

Complete ¹H-NMR and <SUP>13</SUP>C-NMR spectral assignment of five malonyl ginsenosides from the fresh flower buds of Panax ginseng

Yu-Shuai Wang,Yin-Ping Jin,Wei Gao,Sheng-Yuan Xiao,Yu-Wei Zhang,Pei-He Zheng,Jia Wang,Jun-Xia Liu,Cheng-He Sun,Ying-Ping Wang 고려인삼학회 2016 Journal of Ginseng Research Vol.40 No.3

Background: Ginsenosides are the major effective ingredients responsible for the pharmacological effects of ginseng. Malonyl ginsenosides are natural ginsenosides that contain a malonyl group attached to a glucose unit of the corresponding neutral ginsenosides. Methods: Medium-pressure liquid chromatography and semipreparative high-performance liquid chromatography were used to isolate purified compounds and their structures determined by extensive one-dimensional- and two-dimensional nuclear magnetic resonance (NMR) experiments. Results: A new saponin, namely malonyl-ginsenoside Re, was isolated from the fresh flower buds of Panax ginseng, along with malonyl-ginsenosides Rb1, Rb2, Rc, Rd. Some assignments for previously published ¹H- and <SUP>13</SUP>C-NMR spectra were found to be inaccurate. Conclusion: This study reports the complete NMR assignment of malonyl-ginsenoside Re, Rb₁, Rb₂, Rc, and Rd for the first time.

THE RECURRENT HYPERCYCLICITY CRITERION FOR TRANSLATION C0-SEMIGROUPS ON COMPLEX SECTORS

Yu-Xia Liang,Zhi-Yuan Xu,Ze-Hua Zhou 대한수학회 2023 대한수학회보 Vol.60 No.2

Let $\{T_t\}_{t\in \Delta}$ be the translation semigroup with a sector $\Delta\subset \mathbb{C}$ as index set. The recurrent hypercyclicity criterion (RHCC) for the $C_0$-semigroup $\{T_t\}_{t\in \Delta}$ is established, and then the equivalent conditions ensuring $\{T_t\}_{t\in \Delta}$ satisfying the RHCC on weighted spaces of $p$-integrable and of continuous functions are presented. Especially, every chaotic semigroup $\{T_t\}_{t\in \Delta}$ satisfies the RHCC.

HEREDITARILY HYPERCYCLICITY AND SUPERCYCLICITY OF WEIGHTED SHIFTS

Yu-Xia Liang,Ze-Hua Zhou 대한수학회 2014 대한수학회지 Vol.51 No.2

In this paper we first characterize the hereditarily hyper- cyclicity of the unilateral (or bilateral) weighted shifts on the spaces L² (N,K) (or L²(Z,K)) with weight sequence {An} of positive invert- ible diagonal operators on a separable complex Hilbert space K. Then we give the necessary and sufficient conditions for the supercyclicity of those weighted shifts, which extends some previous results of H. Salas. At last, we give some conditions for the supercyclicity of three different weighted shifts.

Disjoint supercyclic weighted composition operators

Yu-Xia Liang,Ze-Hua Zhou 대한수학회 2018 대한수학회보 Vol.55 No.4

In this paper, we discovered a sufficient condition ensuring the weighted composition operators $C_{w_1,\varphi_1},\ldots,C_{w_N,\varphi_N}$ were disjoint supercyclic on $H(\Omega)$ endowed with the compact open topology. Besides, we provided a condition on inducing symbols to guarantee the disjoint supercyclicity of non-constant adjoint multipliers $M_{\varphi_1}^*, M_{\varphi_2}^*,\ldots, M_{\varphi_N}^*$ on a Hilbert space $\mathcal{H}$.

Pathological Impact on the Phyllosphere Microbiota of Artemisia argyi by Haze

( Yu-zhu Zhang ),( De-yu Jiang ),( Chi Zhang ),( Kun Yang ),( Huai-fu Wang ),( Xiu-wen Xia ),( Wei-jun Ding ) 한국미생물생명공학회(구 한국산업미생물학회) 2021 Journal of microbiology and biotechnology Vol.31 No.4

The pathological impact of haze upon the phyllosphere microbiota awaits investigation. A moderate degree of haze environment and a clean control were selected in Chengdu, China. Artemisia argyi, a ubiquitously distributed and extensively applied Chinese herb, was also chosen for experiment. Total genome DNA was extracted from leaf samples, and for metagenome sequencing, an Illumina HiSeq 2500 platform was applied. The results showed that the gene numbers of phyllosphere microbiota derived from haze leaves were lower than those of the clean control. The phyllosphere microbiota derived from both haze and clean groups shared the same top ten phyla; the abundances of Proteobacteria, Actinomycetes and Anorthococcuso of the haze group were substantially increased, while Ascomycetes and Basidiomycetes decreased. At the genus level, the abundances of Nocardia, Paracoccus, Marmoricola and Knoelia from haze leaves were markedly increased, while the yeasts were statistically decreased. KEGG retrieval demonstrated that the functional genes were most annotated to metabolism. An interesting find of this work is that the phyllosphere microbiota responsible for the synthesis of primary and secondary metabolites in A. argyi were significantly increased under a haze environment. Relatively enriched genes annotated by eggNOG belong to replication, recombination and repair, and genes classified into the glycoside hydrolase and glycosyltransferase enzymes were significantly increased. In summary, we found that both structure and function of phyllosphere microbiota are globally impacted by haze, while primary and secondary metabolites responsible for haze tolerance were considerably increased. These results suggest an adaptive strategy of plants for tolerating and confronting haze damage.

Exploring the Effect of Overload on the Discontinuous Intention of SNS: The Moderating Effect of Gender

Yu Xiang Xia,Seong Wook Chae 한국데이터전략학회 2021 Journal of information technology applications & m Vol.28 No.5

With the proliferation of smartphones and 5G networks, mobile social network service (SNS) has become an indispensable part of people’s daily lives. However, with the use of SNS, fatigue and withdrawal behavior gradually emerged. Based on The Transactional Theory of Stress and Coping (TTSC), we explored the mechanism of SNS overload on users’ discontinuous intention under the framework of "stressor-strain-outcome". And we also investigated the moderating effects of gender in this process. We hope that through our research, we can help SNS users to reduce unnecessary fatigue, and provide better suggestions for platform designers to adjust product design to improve user experience.

Xia Chen,Tingjie Lu,Longfei Guo,Yu Shen,Chenguang Wang 보안공학연구지원센터 2014 International Journal of Smart Home Vol.8 No.6

Some studies have shown that the attitude and intention of using mobile LBS is strongly influenced by the privacy factor. Since LBS bears prominent privacy attribute, our study selects the aggregation form based on Microblog content in the LBS of SinaMicroblog, namely, LBS Microblog, asthe object of study, acquires an actual Microblog user data sample of over 30,000 items, with over 8.64 million Microblog postings and 20 million Microblog re-postings of these users, conducts a contrastive research on the adoption behavior in LBS of users at Hub nodes and common nodes in social network through relative analysis, and discusses the diffusion rule of LBS through BASS model. The study finds that the structure attribute of users in social network has strong influence on the adoption rule of LBS; the adoption of different types of LBS by users is obviously in consistency; LBS is remarkably influenced by emergencies related to privacy.
