The emergence of a vast international financial market generates the new benefit through financial transaction in addition to the original target of greenhouse gas reduction. Currently, most of the transactions are being conducted in Europe. However, it appears to be unstable that fluctuation in prices rises dramatically. Price stability of emissions is an important part in that it determines the success or failure of this institute. Emissions trading scheme aims to reduce greenhouse gas emissions reductions of more than quota set, but it is difficult to expect that there is a problem. In addition, technical problems appear to be unstable when operating initially in Europe price. Emissions have a structure that is vulnerable to price fluctuations, especially in situations of sudden changes in demand and supply. Besides, permission of carrying over the emissions to stabilize the comprehensive emissions will cause the moral hazard. 배출권 거래라는 거대한 국제금융시장의 출현은 온실가스 감축이라는 당초 목표 외에 금융거래를 통한 새로운 이익구조를 탄생시킨다. 현재 배출권 거래는 유럽에서 대부분의 거래가 이루어지고 있으나 가격변동이 크게 일어나는 등 불안정한 모습을 보였다. 배출권의 가격안정은 이 제도의 성패를 결정할 만큼 중요한 부분이다. 배출권 거래제도는 온실가스 감축에 목적이 있지만 정해진 할당량 이상의 감축 효과는 기대하기 어렵다는 문제가 있다. 또한 운영기술상의 문제에서 유럽에서의 시행초기 가격변동폭이 커지는 등 운영에 불안정한 모습을 보였다. 특히 배출권은 공급과 수요가 공개된 상황으로 갑작스러운 수급변화에 따른 가격변동에 취약한 구조를 가진다. 또한 이를 안정화하기 위해 배출권의 이월을 포괄적으로 허용하면 도덕적 해이를 야기할 우려도 커진다.

This study deals with the characteristics of the infographic that affect consumer purchasing intent by expressing product information more effectively in e-learning detail pages. The purpose is to determine how usefulness, ease of understanding, and efficiency in the characteristics of infographics affect consumers' intention to purchase content (paid e-learning). To this end, the definition, the components, and the characteristics regarding infographics and purchase intention were confirmed by precedent research. Case analysis followed it regarding three of the paid e-learning detail pages using infographics. After establishing a research model and research hypothesis based on previous studies, a questionnaire survey was conducted on the detailed pages with infographics, comparing with the ones without infographics. The purchase intention consisted of four variables and a demographic survey. The survey period was conducted online for two weeks since May 8, 2020. A total of 357 people participated in the survey. 238 copies of the survey were used as research data. Based on the collected questionnaire data, multiple regression analysis was performed using the SPSS 18 statistical program. As a result, the usefulness, ease of understanding, and efficiency of the infographic have a positive effect on purchase intention. The results of this study provide the following practical implications: for the creation of paid e-learning detail pages in the future that the relationship between layout, graphics, colors, and typography, which are the four elements of the detail page, should be considered so that the target user can quickly grasp the details of the detail page. Detailed pages that can meet users' expectations as much as possible also have the effect of inducing a shift from competing brands. Therefore, if a detailed page of the product well adapts the characteristics of the infographic based on these research results, it could increase the purchase intention of its users.

Human HS1BP3 induces cell apoptosis and activates AP-1

( Tai Ping Shi ),( Jie Shi Xie ),( Ying Xiong ),( Wei Wei Deng ),( Jin Hai Guo ),( Feng Wang ),( Da Long Ma ) 생화학분자생물학회(구 한국생화학분자생물학회) 2011 BMB Reports Vol.44 No.6

In the present study, we characterized the function of HS1-binding protein 3 (HS1BP3), which is mutated in essential tremor and may be involved in lymphocyte activation. We found that HS1BP3 localized to the mitochondria and endoplasmic reticulum partially. Overexpression of HS1BP3 induced apoptosis in HEK293T and HeLa cell lines. When these cell lines were transfected with HS1BP3, they exhibited nuclear DNA condensation, externalization of phosphatidylserine (PS), and cleavage of poly ADP ribose polymerase (PARP). Furthermore, suppression of HS1BP3 or HS1 expression attenuates HS1BP3 induced apoptosis. In addition, HS1BP3 enhanced activator protein 1 (AP-1)-mediated transcription in a dose-dependent manner. Therefore, we conclude that HS1BP3 regulates apoptosis via HS1 and stimulates AP-1-mediated transcription. [BMB reports 2011; 44(6): 381-386]

Simultaneous Multiplexed Detection of Protein and Metal Ions by a Colorimetric Microfluidic Paper-based Analytical Device

Xiaolu Xiong,Junlin Zhang,Zhou Wang,Chenchen Liu,Wende Xiao,Junfeng Han,Qingfan Shi 한국바이오칩학회 2020 BioChip Journal Vol.14 No.4

In order to improve the efficiency of disease diagnosis and environmental monitoring, it is desirable to detect the concentration of proteins and metal ions simultaneously, since the current popular diagnostic platform can only detect proteins or metal ions independently. In this work, we developed a colorimetric microfluidic paper-based analytical device (μPAD) for simultaneous determination of protein (bovine serum albumin, BSA) and metal ions [Fe(III) and Ni(II)]. The μPAD consisted of one central zone, ten reaction zones and ten detection zones in one device, in which reaction solutions were effectively optimized for different types of chromogenic reactions. Fe(III), Ni(II) and BSA can be easily identified by the colored products, and their concentrations are in good accordance with color depth based on the established standard curves. The detection limits are 0.1 mM for Fe(III), 0.5 mM for Ni(II) and 1μM for BSA, respectively. Best of all, we demonstrated the efficiency of the μPAD with accurate detection of Fe(III), Ni (II) and BSA from river water samples within 15 minutes. The μPAD detection is efficient, instrument-free, and easy-to-use, holding great potential for simultaneous detection of cross type analytes in numerous diagnostic fields.

Li, Shi-Lai,Su, Ming,Peng, Tao,Xiao, Kai-Yin,Shang, Li-Ming,Xu, Bang-Hao,Su, Zhi-Xiong,Ye, Xin-Ping,Peng, Ning,Qin, Quan-Lin,Chen, De-Feng,Chen, Jie,Li, Le-Qun Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.1

Background: Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, and the outcomes for patients are still poor. It is important to determine the original type of synchronous multinodular HCC for preoperative assessment and the choice of treatment therapy as well as for the prediction of prognosis after treatment. Aims: To analyze clinicopathologic characteristics and prognoses in patients with multicentric occurrence (MO) and intrahepatic metastasis (IM) of synchronous multinodular hepatocellular carcinoma (HCC). Methods: The study group comprised 42 multinodular HCC patients with a total of 112 nodules. The control group comprised 20 HCC patients with 16 single nodular HCC cases and 4 HCC cases with a portal vein tumor emboli. The mitochondrial DNA (mtDNA) D-loop region was sequenced, and the patients of the study group were categorized as MO or IM based on the sequence variations. Univariate and multivariate analyses were used to determine the important clinicopathologic characteristics in the two groups. Results: In the study group, 20 cases were categorized as MO, and 22 as IM, whereas all 20 cases in the control group were characterized as IM. Several factors significantly differed between the IM and MO patients, including hepatitis B e antigen (HBeAg), cumulative tumor size, tumor nodule location, cirrhosis, portal vein and/or microvascular tumor embolus and the histological grade of the primary nodule. Multivariate analysis further demonstrated that cirrhosis and portal vein and/or microvascular tumor thrombus were independent factors differentiating between IM and MO patients. The tumor-free survival time of the MO subjects was significantly longer than that of the IM subjects ($25.7{\pm}4.8$ months vs. $8.9{\pm}3.1$ months, p=0.017). Similarly, the overall survival time of the MO subjects was longer ($31.6{\pm}5.3$ months vs. $15.4{\pm}3.4$ months, p=0.024). The multivariate analysis further demonstrated that the original type (p=0.035) and Child-Pugh grade (p<0.001) were independent predictors of tumor-free survival time. Cirrhosis (p=0.011), original type (p=0.034) and Child-Pugh grade (p<0.001) were independent predictors of overall survival time. Conclusions: HBeAg, cumulative tumor size, tumor nodule location, cirrhosis, portal vein and/or microvascular tumor embolus and histological grade of the primary nodule are important factors for differentiating IM and MO. MO HCC patients might have a favorable outcome compared with IM patients.
