        NANOSIZED HYDROXYAPATITE/COLLAGEN COMPOSITE

        Feng, Feng, Q,L,Cui, Cui, F.Z,Wang, Wang, R.Z,Du, Du, C,Li, Li, H.D 한국재료학회 1995 Fabrication and Characterization of Advanced Mater Vol.1 No.2

        This paper reported the synthesis of a nano-Hydroxyapatite(HAp)/collagen biocomposite and its biological performances. A thoroughly mixed slurry of type I collagen in supersaturated HAp solution was obtained. HAp was then controlled to precipitate on collagen by adjusting the solution properly. SEM, XRD and TEM analysis reveals that HAp in the composite was nanometer sized and uniformly dispersed oncollagen matrix. In vitro biocompatibility of this new biomaterial was evaluated in terms of its biodegradation and bioactivity. The mice macrophage and osteoblast were used for the study, and the behavior of the cells in contact with the composite was investigated by means of SEM. The observations showed that the composite can be degraded through extracellular resorption process mediated by macrophage, and they can also be well-contact with osteoblast cells, in vitro.

        An Orbital Design Method for Satellite Formation Flying

        Cui Hai-Ying,Li Jun-Feng,Gao Yun-Feng The Korean Society of Mechanical Engineers 2006 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.20 No.2

        An orbital design method of the formation initialization based on the relative orbital element method is presented. It firstly constructed the relative motion equation of the satellite formation flying in terms of the leader and followers' orbital elements. Then the equation was simplified when the orbit eccentricity of the leader satellite was small. And according to the satellites' mission, a general design method for the relative trajectory was proposed. The advantage of this method is that one can get a very simple analytical formula of each follower satellite's orbital elements when the orbital eccentricity of the leader satellite is zero. The simulation results show that the method is effective.

        Colorimetric Detection of Hg2+ Based on Enhancement of Peroxidase‐like Activity of Chitosan‐Gold Nanoparticles

        Cui-Feng Jiang,Zhuojian Li,Yinxing Wu,Jinshan Wang,Qiong Jiang 대한화학회 2018 Bulletin of the Korean Chemical Society Vol.39 No.5

        Hg2+ is a serious environmental contaminant that can cause severe damage to the immune and nervous systems, and Hg2+ monitoring is critical. Herein, we report a novel, simple, and sensitive Hg2+ sensor based on the enhanced peroxidase?like activity of chitosan?gold nanoparticles (CS?AuNPs). The peroxidase?like activity of the CS?AuNPs can be markedly enhanced by Hg2+ as seen by the deeper color and increased absorbance at 652?nm. This improved catalytic ability was used to develop a sensitive and selective colorimetric sensor for Hg2+ detection. The limit of detection via the absorption spectra is as low as 0.02??M. The mechanism underlying the enhanced catalytic ability is discussed. This approach is label?free, simple, and offers detection with the naked eye. Thus, it has potential applications for the detection of Hg2+ in environmental and food samples.

        论集体肖像的使用问题

        Cui Feng(崔峰) 원광대학교 법학연구소 2015 圓光法學 Vol.31 No.2

        Because of group portrait right's specificity, when one exercising its own personal portrait right, he or she can't neglect the group portrait right. But because of the group portrait right also belongs to the right of portrait, so it also having portrait right's features. Personal portrait whether covered by group portrait, should be based on its identifiable characteristics. Then we could classify the group portrait as following two kinds: having distinct person and don't have distinct person. From the view of portrait right's content and the dispute of group portrait, exercising the group portrait is a right of privacy. But when the right's exercise is aiming at social public benefits, the privacy right should be limited. 集体肖像因形式上的特殊性使得个人肖像的使用不得忽略集体肖像的整体性,但其仍属于肖像的范畴应具备肖像的特点。个人肖像是否被集体肖像涵盖应基于肖像的可辨认性特点判断,基于此可以分为能够辨认突出人物的集体肖像和无法清晰辨认突出人物的集体肖像。 从肖像权的内容与集体肖像使用纠纷的现实纬度看,集体肖像的使用是一种自我决定权的行使,但在以社会公共利益为目的使用时应限制其自我决定权。

        论民法典中违约精神精神损害赔偿制度

        崔峰(CUI FENG) 원광대학교 법학연구소 2021 圓光法學 Vol.37 No.2

        위약책임 중 정신손해배상청구의 가능여부는 여태껏 우리나라의 쟁론대상이였다. <<민법전>> 반포이전 정신손해배상문제는 우리나라 민사제도상 불법행위법의 범주에서 다루어졌다. 계약법상 위약행위로 인한 정신손해배상청구에 대하여서는 명확한 규정을 두지 않고 있었다. 사법실천상 다수의 판례도 정신손해배상을 위약책임의 범주에 귀속시키지 않았다. <<민법전>>은 정신손해배상제도에 대하여 중대한 개변을 하였는 바 제996조에서는 위약정신손해배상제도를 규정하였다. 즉 위약행위가 일방 당사자의 인격권을 침해하여 엄중한 정신손해를 조성할 시 피해자가 위약책임에 대한 청구는 위약일방에 대한 정신손해배상청구를 제한하지 않는다고 규정하였다. 여기서 <<정신손해해상청구를 제한하지 않는다>>를 어떻게 이해하는가는 우리가 위약손해배상책임의 적용전제, 배상범위등 문제에서 해석해볼 필요가 있다. It has always been controversial in our country whether mental damages can be claimed in the liability for the breach of contracts.Before the promulgation of the Civil Code of China, the civil law of our country stipulates that the compensation for mental damage is within the scope of the tort liability law.There are no clear provisions in contract law as to whether mental damages can be claimed for the breach of contracts.Nor is mental damages included in most cases in judicial practice in liability for the breach of contract.The Civil Code has brought great changes to the compensation system for mental damages, which stipulates the compensation system for mental damages by default in Article 996 of the Civil Code.That is, when the breach of contracts damages a party s right to personality, the injured party claims that the breach of contracts does not affect its claim to the breach party for compensation for mental damages.How to understand the “no impact” here is worth examining from the perspective of the applicable conditions and the scope of compensation for mental damages. 违约责任中能否请求精神损害赔偿在我国一直存在争议。我国《民法典》颁布之前对于精神损害赔偿问题,我国的民事法律制度上将其规定为侵权责任法的范畴内。在合同法上对于因违约行为能否请求精神损害赔偿并没有明确规定。司法实践中多数案例也并没有将精神损害赔偿包含在违约责任范畴当中。对于精神损害赔偿制度,《民法典》做出了重大改变,在《民法典》第996条中规定了违约精神损害赔偿制度。即违约行为损害了一方当事人的人格权造成严重精神损害时,受害方主张违约责任不影响其向违约方主张精神损害赔偿。这里的“不影响”应如何理解值得我们从违约精神损害赔偿的适用条件、赔偿范围等角度研究。

        On Reservation Contract

        최봉 ( Cui Feng ) 제주대학교 법과정책연구원 2016 국제법무 Vol.8 No.1

        Contract law stipulates the system of sales contract with 46 articles, but these are difficult to solve the complexity and diversity of business contract relationship and the problems that come from the change of market transactions. The pre-contract originated from the traditional consensual contract, the content of the contract is to avoid the other party withdraw intention at will and damage the interests of the other party`s trust. Based on the freedom of contract, pre-contract can be applied to acceptance contract, so as to make the market transactions more flexible. Pre-contract is a consensus in order to make a contract in the future and play a key role in the fierce market competition to stable trading opportunities. Although article 4 and article 5 of the judicial interpretation of commercial housing sales contracts issued in 2003 involves the pre-contract, the content is about the deposit penalty rules and it is not regarded as a complete contract. Article 2 of the judicial interpretation of the contract of sale issued in 2012 identified subscription book, order book, letters of intent, memorandum, etc as pre-contract. If a person does not fulfill its obligation of entering into a sales contract in the future, he should bear the corresponding liability for breach of contract. Article 2 of the judicial interpretation of the contract of sale has important implications for recognition of pre-contract and its effectiveness. However, there is still a too general question in the specific operation on the cognizance of the border of pre-contract and liability for breach of contract. When decide whether to make a pre-contract as the contract, with the content of the standard cannot accurately define pre-contract scope. The key of pre-contract is to conclude the following contract about the contracting intent in the future. Since the pre-contract is an independent contract, it should be different from real contract and the contract with condition as well as subscription book and letters of intent. The party has the obligation of good faith consultations to enter into a contract. While this kind of good faith consultations does not produce the contracting fault liability, it is the premise of the liability for breach of contract obligation. Comparing with must consultation, should conclude a treaty and content decided to say, as well as referring to the form of responsibility of the liability for breach of contract, in violation of the pre-contract produces independent right of claim the same as violating the real contract, which can request a forced default continues to perform. If the losses due to the loss of trading opportunities, you can request for damages, deposit or liquidated damages to constrain the parties concerned.
