옌솨이(YAN SHUAI),호홍옌(HOU HONGYAN) 한국어교육연구학회 2020 한국어교육연구 Vol.- No.12
현재 한국 사회는 다문화사회화가 가속적으로 되고 있는 현실이다. 이 과정에서 한국 사회의 다양한 분야에 걸쳐 한국어 교육의 중요성도 커지고 있다. 그러나 다문화사회의 진전에 따라 확장되는 한국어 교육의 분야는 그동안 한국어 교육계가 경험하지 않은 분야가 대부분으로 한국어 교육계의 보다 큰 관심을 요한다. 한국어와 한국 문화에 대해 이해하고 적절하게 표현할 수 있는 능력을 평가할 수 있도록 개발된 ‘한국 문화 인식 평가(Korean Cultural Awareness Test, KCAT)’의 계획은 한국어 평가 영역에서 새로운 분야를 개척할 수 있으며, 한국어는 물론 한국 문화에 대해서도 세계적으로 널리 알릴 수 있는 기회를 제공할 수 있을 것으로 기대된다. 본 논문은 이러한 인식에서 출발하여 평가 등급화, 채점 기준, ‘한국 문화 인식 평가(KCAT)’의 요소 등급화 등을 설계하여 제시하고자 한다. 이에 따라 외국인 한국어 학습자들이 한국 문화 인식 평가를 준비함으로써 한국인의 사고방식과 행위의 특징을 깊이 이해할 수 있도록 하고, 한국문화를 시험기준에 맞춰서 공부하여 외국인 한국 문화 전문가를 양성하는 데 도움이 되었으면 한다. It is a well-known fact that multi-cultural socialization of Korean society is accelerating. During the process, Korean language education parts are growing importantly in the various fields of Korean society. However, the fields of Korean language education that have been expanded according to the progress of the multi-cultural society is the parts that had not been experienced so far. The plan of the Korean Culture Awareness Test (KCAT) which is designed to assess the ability to understand and express properly Korean culture could be a new area in fields of Korean assessment. It is expected to provide an opportunity to expand the Korean and Korean culture globally. Starting from this recognition, this paper intends to design and present grading of assesment, criteria of grading, and evaluating elements of KCAT . This paper aims to present foreign Korean language learners with understanding of Korean ways of thinking and behaviors by preparing Korean Cultural Awareness Test, and to help foreign Korean culture experts to study Korean culture deeply at the same time.

Decision diagram based methods and reliability analysis for k-out-of-n: G systems
Shumin Li,Shudong Sun,Shubin Si,Shuai Zhang,Hongyan Dui 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.10
Binary k-out-of-n systems are commonly used reliability models in engineering practice. Many authors have extended the concept ofk-out-of-n system to multi-state k-out-of-n systems. This paper proposes a binary decision diagram (BDD) based approach for binary kout-of-n: G system and a multi-state multi-valued decision diagram (MMDD) based approach for multi-state k-out-of-n: G system. BDDand MMDD have been extensively used for representing and manipulating logic functions in many areas, including reliability modelingand analysis. In this paper, patterns of BDD/MMDD for binary/multi-state k-out-of-n: G system are summarized and proved, a two-stepalgorithmic process is proposed for modeling the BDD/MMDD and three case studies are implemented to demonstrate the presentedmethods. Complexity analysis shows that the presented method is more computationally efficient than the traditional algorithms for kout-of- n: G system.

BACKGROUND/OBJECTIVES: Inonotus obliquus has been used as antidiabetic herb around the world, especially in the Russian and Scandinavian countries. Diabetes is widely believed to be a key factor in Alzheimer’s disease (AD), which is widely considered to be type III diabetes. To investigate whether I. obliquus can also ameliorate AD, it would be interesting to identify new clues for AD treatment. We tested the anti-AD effects of raw Inonotus obliquus polysaccharide (IOP) in a mouse model of AD (3×Tg-AD transgenic mice). MATERIALS/METHODS: SPF-grade 3×Tg-AD mice were randomly divided into three groups (Control, Metformin, and raw IOP groups, n = 5 per group). β-Amyloid deposition in the brain was analyzed using immunohistochemistry for AD characterization. Gene and protein expression of pertinent factors of the ubiquitin-proteasome system (UPS) was determined using real-time quantitative polymerase chain reaction and Western blotting. RESULTS: Raw IOP significantly reduced the accumulation of amyloid aggregates and facilitated UPS activity, resulting in a significant reduction in AD-related symptoms in an AD mouse model. The presence of raw IOP significantly enhanced the expression of ubiquitin, E1, and Parkin (E3) at both the mRNA and protein levels in the mouse hippocampus. The mRNA level of ubiquitin carboxyl-terminal hydrolase isozyme L1, a key factor involved in UPS activation, also increased by approximately 50%. CONCLUSIONS: Raw IOP could contribute to AD amelioration via the UPS pathway, which could be considered as a new potential strategy for AD treatment, although we could not exclude other mechanisms involved in counteracting AD processing.
