Liu, Zhen-Jie & Jin, Ming-Hao. (2018). A study of the content validity of reading comprehension tests in NMET II. The Linguistic Association of Korea Journal, 26(4), 103-124. Based on Bachman and Palmer’s (1996) framework of task characteristics, this paper aims to compare the reading comprehension tests of the 2013-2017 National Matriculation English Test II (NMET II) with the requirements of the New Curriculum Standards and Testing Syllabus, in particular, concerning the content validity of the tests in terms of the characteristics of input and expected responses. The implications of this study are discussed for test designers, teachers, and students. The results show that reading comprehension tests from 2013 to 2017 basically meet the requirements of the New Curriculum Standard and Testing Syllabus and have a high content validity. In terms of the characteristics of input, the length, reading speed, and readability of comprehension passages are appropriate for students; however, the distribution of topics and genres in each year is uneven. In terms of the characteristics of expected responses, the wordings of questions and the design of question items are reasonable. However, the response type is mainly restricted to selected response questions (multiple-choice), and the measure of reading skills coverage is unbalanced.

This paper presents a development of Switched Reluctance Motor (SRM) drive system for a hoist application. In the hoist system, smoothing start-up and braking are very important for a protection of goods. In order to improved a start-up and a stop performance of hoist system, the smoothing operation sequence of SRM using direct instantaneous torque control is proposed. The proposed Direct Instantaneous Torque Control (DITC) the instantaneous torque of SRM according to the switching sequence and hysteric band. In order to compare the reference and actual torque of SRM, pre-measured flux and torque look-up table are regulate used. The proposed SRM Drive system is verified by the simulation result.

This paper proposes high speed SRM drive system for blower with a novel 4-level inverter and precise excitation position generator. In order to get a fast build-up and a demagnetization of excitation current, 4-level inverter system is proposed. The proposed 4-level inverter has additional charge capacitor, power switch and diode in the conventional asymmetric converter. The charged high voltage is supplied to the phase winding for fast current build- up, and demagnetization current is charged to additional capacitor of 4-level inverter. In addition, a precise excitation position generator can reduce turn-on and turn-off angle error according to sampling period of digital control system. The proposed high speed SRM drive system is verified by computer simulations and experimental results.

Background: Superior colliculus is a part of midbrain, and participates in the visual reflexes, It receives afferent fibers from optic nerve, visual cortex, and spinotectal tract. After optic deprivation, the microscopic structure of the superior colliculus changed. Calcium-binding proteins (CBPs) Play an important role in the neuronal protection, differentiation and reorganization of the central nervous system, Objectives and Methods: The effects of neonatal retinal deafferentation on a CBPs, calbindm D-28k (CB), Parvalbumin (PB) and calretimn (CR), and the existence of colocalization between the CBPs were examined immunohistochemically in the rat superior colliculus. Results: On the experimental (contralateral to enucleation) side of superior colliculus, the number of CB-immunoreactive (IR) cells was reduced (77.4% compared to control), but not fibers. The number of PB-IR neurons and fibers was also reduced on the experimental side (88.5% compared to control), In the other hand, the CR-IR cells were dramatically increased (642% compared to control), but CR-IR fibers were markedly decreased on the experimental side. The colocalization between CB-CR and PV-CR was rarely observed in the superior colliculus Conclusion: These results suggest that the changes of retinotectal projection may alter the expressional pattern of CBPs in different manners; relatively stable in CB- and PV-IR neurons and plastic in CR-IR neurons.

Jin, Hua,Piao, Shang Guo,Jin, Ji Zhe,Jin, Ying Shun,Cui, Zhen Hua,Jin, Hai Feng,Zheng, Hai Lan,Li, Jin Ji,Jiang, Yu Ji,Yang, Chul Woo,Li, Can S.Karger 2014 The Nephron Journals Vol.126 No.3

<P>Abstract</P><P><B><I>Background:</I></B> Leflunomide (LEF) and benazepril have renoprotective effects on diabetic nephropathy (DN) through their anti-inflammatory and anti-fibrotic activities. This study investigated whether combined treatment using LEF and benazepril affords superior protection compared with the respective monotherapies. <B><I>Methods:</I></B> Diabetes was induced with streptozotocin (STZ, 65 mg/kg) by intraperitoneal injection in male Wistar rats. Two weeks after STZ injection, diabetic rats were treated daily for 12 weeks with LEF (10 mg/kg), benazepril (10 mg/kg), or a combination of both. Basic parameters (body weight, fasting blood glucose level, and 24 h urinary protein excretion), histopathology, inflammatory [inflammatory cell infiltration (ED-1), monocyte chemoattractant protein-1 (MCP-1), and Toll-like receptor-2 (TLR-2)] and glomerulosclerotic factors [transforming growth factor-β<SUB>1</SUB> (TGF-β<SUB>1</SUB>) and connective tissue growth factor (CTGF)], and oxidative stress (8-hydroxy-2'-deoxyguanosine, 8-OHdG) were studied. <B><I>Results:</I></B> Benazepril or LEF treatment significantly prevented body weight loss and 24 h urinary protein excretion induced by diabetes; combined treatment with LEF and benazepril further improved these parameters compared with giving each drug alone (all p < 0.01). Increased expression of inflammatory (MCP-1 and TLR-2) and glomerulosclerotic (TGF-β<SUB>1</SUB> and CTGF) factors in diabetic rat kidney was reduced by treatment with either LEF or benazepril and was further reduced by the combined administration of the two drugs (p < 0.01). These effects were accompanied by suppression of urinary 8-OHdG excretion. There was no significant between-group difference in blood glucose level. <B><I>Conclusions:</I></B> LEF treatment lessens DN, and combined treatment with LEF and benazepril provides synergistic effects in preventing DN.</P><P>© 2014 S.

JIN, Guang-Zhen,YIN, Xi-Jun,YU, Xian-Feng,CHO, Su-Jin,CHOI, Eu-Gene,LEE, Young-S,JEON, Jin-Tae,YEE, Sung-Tae,KONG, Il-Keun Japanese Society of Veterinary Science 2008 The Journal of veterinary medical science Vol.70 No.7

<P>Umbilical cord blood (UCB)-derived mesenchymal stem cells (MSCs) are multipotent adult stem cells, which can differentiation into cells of connective tissue and neural lineages. This study investigated the potential for neuronal differentiation of red fluorescent protein (RFP)-transgenic cat UCB-derived MSCs. The cells were cultured in pre-induction medium for 24 hr and in neuronal-induction medium for 72 hr. Immunofluorescent staining showed that 6.85% of the total cells were β III-tubulin-positive, 3.37% were neurofilament light (NF-L)-positive and 7.04% were neurofilament medium (NF-M)-positive. A β III-tubulin band was detected by western blot analysis. Our results demonstrate that RFP-transgenic UCB-derived MSCs can be differentiated into neuronal cells <I>in vitro</I>. Thus, RFP-transgenic MSCs could provide alternative tracing material for stem cell transplantation.</P>

본 연구는 건강노령화의 정의, 속성, 선행요인, 영향요인, 결과, 의의 및 측정도구에 대해 상세히 분석함으로써 향후 건강노령화의 이론적 연구결과를 간호실천에 응용하는 등 프로그램 개발에 기초자료로 활용될 수 있도록 하기 위함이다. Rodgers의 진화론적 방법을 이용하였고 자료수집은 CNKI, WANFANG DATA, PubMed및Web of Science등 4개 국내외 데이터베이스를 통해 검색되었다. 연구결과는 다음과 같다. 건강노령화는 전 생명주기와 연관이 있으며, 다양한 분야의 협력이 필요하고 개인, 가족, 사회 등 삼요소가 평형을 이루는 상태이다. 건강노령화 개념분석결과는 노령화에 대한 이론연구와 건강노령화 실행에 실질적인 도움을 줄 수 있다고 사료된다. This study undertook a detailed analysis of the definition, attributes, preconditions, influencing factors, results, significance, and measurement tools of healthy aging for their eventual application as basic data for program development, such as applying the theoretical research results of healthy aging to nursing practice. Using Rodgers evolutionary method, data was procured from four domestic and international databases: CNKI, WANFANG DATA, PubMed, and Web of Science. The results show healthy aging is related to the entire life cycle, with various fields being intricately associated. Moreover, the three factors of individual, family, and society are in equilibrium. Results of this study indicate that the conceptual analysis of healthy aging helps in the in-depth study of aging and provides practical help in the implementation of healthy aging, starting with the concept.
