Light intensity degradation is one of the most important parameters in the design of organic light-emitting diodes (OLEDs)for image applications, and it is usually obtained through time-consuming stability tests. The lifetimes are estimated based on the well-known empirical reciprocal relationship between the initial brightness and the half-lifetime, which is assumed to be always valid for all devices. In this work, it was used as a chemical kinetics approach for modeling the light output in time under constant current operation. Through this approach, an equation with only two parameters, one for OLED light output in time and another for half-lifetimes, was obtained. This approach was applied to stability tests for three different OLEDs to determine how their features affect the kinetic parameters and to compare such parameters for OLEDs operating at two temperatures, 22◦C and 70◦C, to determine if they have a correlation with thermal stability.

The Objective of an Environmental Regulatory Agency
Kim, Geum Soo,Neilson, William S . 한국경제학회 2001 The Korean Economic Review Vol.17 No.2
The objective of an environmental regulatory agency in charge of enforcing an environmental standard is studied. It is assumed that the standard and the agency's budget are set by an overseeing authority. It is found that depending on the standard and the budget given to the agency, the agency may or may not behave as if it minimizes noncompliance, even though its true objective is to maximize total profit minus damages. It is also shown that when the higher level agency sets the standard and enforcement budget to maximize social welfare, the agency acts as if it minimizes noncompliance.

2007년에 시작된 서브프라임 금융위기이후 경제학자들과 정치가들은 지난 20년 동안 지배적이었던 신자유주의 발전모델 혹은 금융주도축적체제의 한계에 대하여 인식하기 시작하였다. 그 결과 보다 균형 있고 지속적인 성장을 위해서는 금융개혁과 더불어 임금 몫을 개선시키는 친 노동 분배정책이 필요하다는 것을 제안하게 되었다. 본 연구에서는 글로벌 금융위기를 초래한 원인들과 그 해결책을 알아봄으로써 글로벌 케인지안 뉴딜이 제안된 배경과 그 성공을 위한 조건들을 알아보았다. 임금주도성장전략은 금융부분의 규제강화와 더불어 생산성-임금연동을 복원하여 해결할 것을 제안하고 있다. 이에 덧붙여 글로벌 케인지안 뉴딜의 성공을 위해서는 기업지배구조개선과 소셜덤핑을 유발하는 세계화에 대한 통제 그리고 그린 뉴딜을 도입할 필요성을 강조하였다. 그러나 국가 간 이해의 차이를 고려할 때 이러한 위기탈출을 위한 조정과 국제협상이 용이하지 않음을 지적하였다. By considering the factors that brought about the global financial crisis and measures taken to resolve it, this study looks at the background behind proposals for a Global Keynesian New Deal, and the conditions for its success. We propose that a wage-led growth strategy accompanied by stronger regulation of the financial sector will rebuild the wage-productivity growth link and resolve related issues. In addition, we point out the necessity of corporate governance structure improvements, as well as controls over globalization, which is a cause of social dumping. Finally, we emphasize the need to introduce a “green deal” along with the Global Keynesian New Deal. However, the diversity of interests among countries makes quite problematic the neogotiations of common internatioonal rules and coordination of strategies out of the present crisis.
KMTNET SUPERNOVA PROGRAM VARIABLE OBJECTS I. NGC 2784 FIELD

We present analyses of $\sim$1250 variable sources identified in a 20 square degree field toward NGC~2784 by the KMTNet Supernova Program. We categorize the variable sources into three groups based on their B-band variability. The first group consists of 31 high variability sources with their $B$-band RMS variability greater than 0.3 magnitudes. The second group of medium variability contains 265 sources with RMS variability between 0.05 and 0.3 magnitudes. The remaining 951 sources belong to the third group of low variability with an RMS variability smaller than 0.05 magnitudes. Of the entire $\sim$1250 sources, 4 clearly show periods of variability greater than 100 days, while the rest have periods shorter than $\sim$51 days or no reliable periods. The majority of the sources show either rather irregular variability or short periods faster than 2 days.Most of the sources with reliable period determination between 2 and 51 days belong to the low-variability group, although a few belong to the medium-variability group. All the variable sources with periods longer than 35 days appear to be very red with $B-V$ $>$ 1.5 and $V-I$ $>$ 2.1 magnitudes. We classify candidates of 51 Cepheids, 17 semi-regular variables, 3 Mira types, 2 RV(B) Tauri stars, 26 eclipsing binary systems and 1 active galactic nucleus.The majority of long-term variables in our sample belong to either Mira or semi-regular types, indicating that long-term variability may be more prominent in post-main sequence phases of late-type stars. The depth of the eclipsing dips of the 26 candidates for eclipsing binaries is equivalent to $\sim$0.61 as the average relative size of the two stars in the binary system. Our results illustrate the power of the KMTNet Supernova Program for future studies of variable objects.
Acute and Sub-Chronic Toxicity of Aqueous Extracts of Chenopodium ambrosioides Leaves in Rats

The present study aimed to evaluate the toxicity of aqueous extract of Chenopodium ambrosioides leaves. To measure acute toxicity, rats were administered 0, 0.3, 1.0, or 3.0 g/kg of aqueous extract from C. ambrosioides leaves by gavage. To analyze sub-chronic toxicity, rats were treated by oral gavage for 15 consecutive days with 0, 0.3, or 1.0 g/kg of extract of C. ambrosioides leaves. No animals from either trial exhibited any signs of toxicity. In the acute study, the highest dose of the extract led to an increase in the serum activities of alanine transaminase (ALT) and aspartate transaminase (AST) and a decrease in the serum levels of urea. In the sub-chronic test, rats treated with 1.0 g/kg for 15 days exhibited increased serum ALT activity and creatinine levels and mild cytoplasmic vacuolation of hepatocytes. The results indicate that aqueous extract from C. ambrosioides leaves produce slight hepatotoxic lesions in rats.
Results of availability imposed configuration details developed for K-DEMO
Brown, T.,Titus, P.,Brooks, A.,Zhang, H.,Neilson, H.,Im, K.,Kim, K. North-Holland ; Elsevier Science Ltd 2016 Fusion engineering and design Vol.109 No.2
The Korean fusion demonstration reactor (K-DEMO) has completed a two year study looking at key Tokamak components and configuration options in preparation of a conceptual design phase. A key part of a device configuration centers on defining an arrangement that enhances the ability to reach high availability values by defining design solutions that foster simplified maintenance operations. To maximize the size and minimize the number of in-vessel components enlarged TF coils were defined that incorporate a pair of windings within each coil to mitigate pressure drop issues and to reduce the cost of the coils. A semi-permanent shield structure was defined to develop labyrinth interfaces between double-null plasma contoured shield modules, provide an entity to align blanket components and provide support against disruption loads-with a load path that equilibrates blanket, TF and PF loads through a base structure. Blanket piping services and auxiliary systems that interface with in-vessel components have played a major role in defining the overall device arrangement-concept details will be presented along with general arrangement features and preliminary results obtained from disruption analysis.
