YKL-40, a secreted glycoprotein, may serve as an autoantigen, which mediates multipleinflammatory diseases and cancers. A high YKL-40 serum level is correlated with metastasisand poor survival in a variety of human cancers. However, the role of YKL-40 in dogs is stillunder evaluation. Herein, we examined the associations between plasma YKL-40 level andYKL-40 autoantibody (YAA) titers with malignancy and prognosis in canine cancer. Plasmalevels of YKL-40 in healthy dogs (n = 20) and in dogs (n = 82) with cancer were evaluatedusing enzyme-linked immunosorbent assay. Our results indicated that plasma YKL-40 levelswere significantly higher (p < 0.01) in dogs with cancer than in healthy dogs. A significantdecrease in the YAA titers was detected in the dogs with cancer when compared with thoseof the healthy dogs (p < 0.05), although the change was not correlated with the YKL-40levels. Among the dogs with cancer, plasma YKL-40 levels in the dogs that later relapsed orhad metastasis were significantly higher than in the dogs with no signs of relapse (p < 0.01)or metastasis (p <0.05). The relapse and metastasis rates were significantly higher in thehigh YKL-40 group (> 180 pg/mL) than in the low YKL-40 group (< 180 pg/mL). The resultsimply that plasma YKL-40 levels might have the potential to be developed as a marker ofmalignancy progression and prognosis in canine cancers.
New functional glasses containing semiconductor quantum dots
Xu, Kai,Heo, Jong Royal Swedish Academy of Sciences 2010 Physica scripta Vol.2010 No.t139
<P>CdSe and PbSe quantum dots (QDs) were precipitated in oxide glass matrices and their optical properties were investigated. The size of QDs could be controlled using careful heat treatment. The quantum confinement effect was clearly observed, as evidenced by a shift in the peak wavelengths of absorption. It was possible to control also the wavelength of the photoluminescence bands of CdSe and PbSe QDs by using thermal treatment.</P>
NONLINEAR MICROWAVE-OPTOELECTRONIC PERFORMANCE OF A GaAs CPW-TO-SLOTLINE RING RESONATOR
Lee,Jong Chul,Taylor,Henry F.,Chang,Kai 대한전자공학회 1995 ICVC : International Conference on VLSI and CAD Vol.4 No.1
A novel unlplanar ring resonator is fabricated on semiinsulating GaAs substrate and a Shottky photodetector is monolithically integrated as a coupling gap into a CPW(Coplanar waveguide)-to-Slotline ring resonator. Honlinear interaction between an optically modulated signal and a microwave local oscillator signal is obtained.

The Chinese e-commerce market is steadily growing. With the popularization of e-commerce platforms such as Alibaba and Jingdong, emerging enterprises have achieved success in a short period of time. Recently, the influence of international e-commerce policy and the development of low-temperature distribution system have led to an increase online food shopping in China. Especially, as the purchasing power of Chinese people becomes stronger, the need for nutritional health and convenient food increases, and the policy of the Chinese government also helps the development of the leisure food industry. First, because of the time and physical constraints, the numbers of survey collected were limited and large-scale sample surveys were not conducted. Second, The ages to be surveyed were in their twenties and thirties, and occupation was concentrated on office workers and students. Third, customer satisfaction of online leisure food shopping has a significant effect on customer loyalty and repurchase intention. Therefore, studying how customer satisfaction of online leisure food shopping affects customer loyalty and repurchase intention will become a valuable research direction in the future. Lastly, in this study, I have adopted the factors of purchasing factors on online leisure food through existing literature studies, but there is a limit to present the factors that influence purchase factors. Therefore, further study is needed to clarify the effects and relationships between various variables that may affect purchase factors.
BIG의 건축에서 나타나는 스토리텔링에 의한 형태생성 프로세스와 표현 특성에 관한 연구
김종성(Kim, Jong-Sung),김개천(Kim, Kai-Chun) 한국실내디자인학회 2015 한국실내디자인학회논문집 Vol.24 No.6
This study started from the concern for Bjrake Ingels, an emerging architect in the architecture circle, who is creative and popular. Recently, the architecture field provides architects with a foundation to express a process on a new form creation through various new expressive languages, design concepts, and methods. The global Danish group BIG(Bjarke Ingels Group) develops a story by their distinctive architectural language. The storytelling is being used in various fields and now the tool called `story` is settling down as an important element in the life that human lives. Bjarke Ingels leading the group BIG aims for the form expression by the scientific analysis and adaptation after being affected by Danish regional background and OMA. It creates a form to share stories with local members by visually simplifying the region, culture, environment, social phenomenon, economy, and politics that are invisible and do not have the form in the modern society. The elements and expressive features of the space storytelling include locality, cultural, natural environment, and connectivity, which are the content structure(story) that enables you to intervene in the story according to the main agent to imagine a new space. The expressive element includes the watching moving line story of the successive, hierarchical, and organic structures which are constructive elements creating various spaces through the mixture, transmutability, and relocation of the program and inducing users to the space. The space storytelling is composed of the symbolism, community, and eco-friendliness to appear diversely through BIG`s case analysis. This study will have significance that it drew a method and feature looked at by many contemporary architects from the storytelling viewpoint in the form-creating process, classified the form-creating process through a new storytelling type, and showed a possibility on the development of various methodologies.

This paper presents an analytical technique for reliability evaluation of electrical distribution network (EDN) containing distributed generation (DG). Based on hierarchical levels of circuit breaker controlling zones and feeder sections, a directed-relation-graph (DRG) for an END is formed to describe the hierarchical structure of the EDN. The reliability indices of EDN and load points can be evaluated directly using the formed DRG, and the reliability evaluation of an EDN containing DGs can also be done without re-forming the DRG. The proposed technique incorporates multi-state models of photovoltaic and diesel generations, as well as weather factors. The IEEE-RBTS Bus 6 EDN is used to validate the proposed technique; and a practical campus EDN containing DG was also analyzed using the proposed technique.
