This study investigated the effects of reading syntactically visualized text format on EFL learners’ reading comprehension. Visual-syntactic text formatting (VSTF) technology was used to analyze underlying English syntactic structures and transform linear text format into hierarchically structured format. Korean middle school students (Grade 8, n = 95) participated in this 15-week classroom experiment. A pretest-posttest analysis showed that VSTF groups had significantly higher scores on the reading comprehension test over controls who used linearly formatted conventional text (p < .01). This result was similar across low and high proficiency students. The results from the questionnaire demonstrated that VSTF groups were able to parse sentences into bigger chunks than controls at a statistically significant level at the level of .01. In addition, VSTF groups preferred VSTF reading and the reading instruction with it, believing that VSTF is helpful for improving their English reading skills.

오로사,조영아 이화여자대학교 특수교육연구소 2021 특수교육 Vol.20 No.3

연구목적: 본 연구의 목적은 발달장애인 부모의 삶의 질에 영향을 미치는 다양한 요인을 이해하여 이들의 삶의 질을 높일 수 있는 방안을 마련하는 것이다. 연구방법: 서울, 인천, 경기에 거주하고 있는 발달장애인 부모 180명을 대상으로 삶의 질 간편형 척도, 문제행동질문지, 삶의 지향성 척도, 영성평가척도를 실시하였다. 부모의 삶의 질에 대한 발달장애인 자녀의 문제행동, 사회적 지원, 성격강점의 위계적 영향력 알아보기 위해 위계적 중다회귀분석을 하였다. 연구결과: 첫째, 발달장애자녀의 심각도는 삶의 질에 부적으로 유의미한 영향요인으로 나타났으며, 부모의 자조모임활동 참여, 부모의 성격강점(낙관성, 영성)은 삶의질에 정적으로 유의미한 영향요인으로 나타났다. 둘째, 자녀의 문제행동, 사회적 지원, 부모의 성격 강점은 부모의 삶의 질의 변량의 80%의 설명량을 보였으며, 성격강점(낙관성, 영성)은 부모의 삶의 질에 대한 설명력을 크게 증가시켰다. 결론: 발달장애인 부모의 삶의 질을 높이기 위해서는 발달장애 자녀에 대한 전문적인 치료적 개입과 자조 모임의 활성화, 부모의 낙관성과 영성을 향상시킬 수 있는 교육 및 상담 지원이 필요함을 강조하였다. Purpose: The purpose of this study is to come up with measures to improve the quality of life of parents with developmental disabilities by understanding the various factors that affect the quality of life. Method: The quality of life scale(WHOQOL-BREF), problem behavior questionnaire, life orientation test(LOT-R) and spirituality assessment scale(SAS) were conducted for 180 parents of children with developmental disabilities residing in Seoul, Incheon, and Gyeonggi Province. A hierarchical multiple regression analysis was conducted to investigate the hierarchical influence of problem behaviors, social support, and personality strengths of children with developmental disabilities on their parents' quality of life. Results: First, the severity of children with developmental disabilities was shown as a negatively significant influence on quality of life, and the participation of parents in self-help activities and their personality strengths (optimality and spirituality) were shown as statically significant influences on quality of life. Second, children's problematic behavior, social support, and parental personality strengths accounted for 80% of the parents' quality of life, and personality strengths (optimality and spirituality) greatly increased parents' quality of life. Conclusion: In order to improve the quality of life of parents with developmental disabilities, they emphasized the need for professional therapeutic intervention in children with developmental disabilities, revitalization of self-help groups, education and counseling support to improve parents' optimism and spirituality.

본 연구는 수평적 결합이 개별 SO의 경영성과에 미치는 영향에 대한 기존의 연구들이 서로 엇갈린 결과를 내놓고 있는 것에 주목해 연결망 연구(Network Analysis)라는 새로운 접근 방법을 사용하여 엇갈린 연구 결과들에 대한 정확한 이해를 목적으로 진행되었다. 따라서 본 연구에서는 주식지분관계의 연결망으로부터 관계적 속성(연결망 변인)을 이끌어내어 기존의 성과변인을 특성변인과 행위변인으로 구성하여 상관분석과 다중회귀분석을 통해 수평적 결합이 개별 SO의 경영성과에 미치는 실질적 영향력을 검증하고자 하였다. 연구의 결과는 다음과 같다. 첫째, 케이블 SO들의 지분연결망은 배타적이고 약한 연결망(weak tie)의 특징을 지닌다. 둘째, 지분출자가 영업행위와 관련된 자원과 정보의 효율적인 통제에는 영향을 미치지 못하는 것으로 나타났다. 셋째, 그러나 수평적 결합이 비용(지출)이 포함된 가구당 매출액과 같은 외형적 성과에는 효과가 있다고 볼 수 있다. 넷째, 전체적으로 내향중심성은 행위변인과, 외향중심성은 속성변인과 상관관계가 높고 구속성은 비용과 상관관계가 높은 것으로 나타났다. 수평적 결합이 매출액에는 긍정적 영향을 미치지만, 영업이익과 당기순익을 높이는 데에는 오히려 부정적 영향을 나타냈다는 점에서 현시점에서 수평적 결합은 자원과 정보의 효율적 활용을 통한 경영성과의 증대에 긍정적인 영향을 미치는 것으로 보기 어렵다. This study is for reexamination of economic performance of cable service operators since previous researches has presented inconsistent results. Thus, the study constructed relational traits(network variables) from stock relationship network of cable service operators. Also, traditional performance variables are constructed with trait variables and conduct variable and correlational analysis and multi-regression was conducted to prove actual effect of horizontal association among cable service operators. As a result, first, stock relationship network of cable service operator is exclusive and weak tie. Second, investing in other cable service operators does not guarantee effective control of resources and information related to sales. Third, but, horizontal association is effective on external performance such as the sales per household. Fourth, incloseness centrality and out-closeness centrality has high correlation with conduct variables and trait variables relatively. Also, constraint is correlated with the cost. In summary, even though horizontal association has positive effect on the sales, it has rather negative effects on increasing sales profit and the net income. This result suggests that horizontal association known to be effective for efficient utilization of resources and informations would not be the best choice for cable service operators to increase economic performance.

Molecular Phenotyping Small (Asian) versus Large (Western) Plaque Psoriasis Shows Common Activation of IL-17 Pathway Genes, but Different Regulatory Gene Sets

Kim, Jaehwan,Oh, Chil-Hwan,Jeon, Jiehyun,Baek, Yoosang,Ahn, Jaewoo,Kim, Dong Joo,Lee, Hyun-Soo,da Rosa, Joel Correa,Suá,rez-Fariñ,as, Mayte,Lowes, Michelle A.,Krueger, James G. Nature Publishing Group 2016 The Journal of investigative dermatology Vol.136 No.1

<P>Psoriasis is present in all racial groups, but in varying frequencies and severity. Considering that small plaque psoriasis is specific to the Asian population and severe psoriasis is more predominant in the Western population, we defined Asian <I>small</I> and <I>intermediate</I> plaque psoriasis as psoriasis subtypes, and compared their molecular signatures with classic subtype of Western <I>large</I> plaque psoriasis. Two different characteristics of psoriatic spreading—vertical growth and radial expansion—were contrasted between subtypes, and genomic data were correlated to histologic and clinical measurements. Compared to Western <I>large</I> plaque psoriasis, Asian <I>small</I> plaque psoriasis revealed limited psoriasis spreading, but IL-17A and IL-17-regulated pro-inflammatory cytokines were highly expressed. Paradoxically, IL-17A and IL-17-regulated pro-inflammatory cytokines were lower in Western <I>large</I> plaque psoriasis, while T cells and dendritic cells in total psoriatic skin area were exponentially increased. Negative immune regulators, such as CD69 and FAS, were decreased in both Western <I>large</I> plaque psoriasis and psoriasis with accompanying arthritis or obesity, and their expression was correlated with psoriasis severity index. Based on the disease subtype comparisons, we propose that dysregulation of T cell expansion enabled by downregulation of immune negative regulators is the main mechanism for development of large plaque psoriasis subtypes.</P>

Purpose: We aimed to elucidate the relationship between the knowledge, nursing performance, and stress of delirium in cancer hospital nurses. The results might help provide better and appropriate nursing care to patients with delirium. Methods: As a descriptive study, 143 nurses who had worked for over one year at one cancer hospital in S city were included in this study. The data collection period was from February 1 to 15, 2021. Results: It was found that cancer hospital nurses with delirium-related nursing education had a high knowledge of delirium. Cancer hospital nurses who were married and had an educational background above graduate school showed relatively high nursing performance against delirium. Also, cancer hospital nurses had relatively high stress levels. Conclusion: Therefore, an opportunity to develop and participate in a systematic education program is necessary to raise cancer hospital nurses’ knowledge levels of delirium and improve nursing performance for delirium. Furthermore, it is necessary to have a stress management program for delirium for cancer hospital nurses.

A Bifunctional Molecule as an Artificial Flavin Mononucleotide Cyclase and a Chemosensor for Selective Fluorescent Detection of Flavins

Rhee, Hyun-Woo,Choi, So Jung,Yoo, Sang Ho,Jang, Yong Oh,Park, Hun Hee,Pinto, Rosa Marí,a,Cameselle, José,Carlos,Sandoval, Francisco J.,Roje, Sanja,Han, Kyungja,Chung, Doo Soo,Suh, Junghun American Chemical Society 2009 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.131 No.29

<P>Flavins, comprising flavin mononucleotide (FMN), flavin adenine dinucleotide (FAD), and riboflavin (RF, vitamin B(2)), play important roles in numerous redox reactions such as those taking place in the electron-transfer chains of mitochondria in all eukaryotes and of plastids in plants. A selective chemosensor for flavins would be useful not only in the investigation of metabolic processes but also in the diagnosis of diseases related to flavins; such a sensor is presently unavailable. Herein, we report the first bifunctional chemosensor (PTZ-DPA) for flavins. PTZ-DPA consists of bis(Zn(2+)-dipicolylamine) and phenothiazine. Bis(Zn(2+)-dipicolylamine) (referred to here as XyDPA) was found to be an excellent catalyst in the conversion of FAD into cyclic FMN (riboflavin 4',5'-cyclic phosphate, cFMN) under physiological conditions, even at pH 7.4 and 27 degrees C, with less than 1 mol % of substrate. Utilizing XyDPA's superior function as an artificial FMN cyclase and phenothiazine as an electron donor able to quench the fluorescence of an isoalloxazine ring, PTZ-DPA enabled selective fluorescent discrimination of flavins (FMN, FAD, and RF): FAD shows ON(+), FMN shows OFF(-), and RF shows NO(0) fluorescence changes upon the addition of PTZ-DPA. With this selective sensing property, PTZ-DPA is applicable to real-time fluorescent monitoring of riboflavin kinase (RF to FMN), alkaline phosphatase (FMN to RF), and FAD synthetase (FMN to FAD).</P>

This narrative inquiry explores how good English language learners’ (GELLs) L2 motivation and usage of language learning strategies change over time based on the onset age of active English learning in the Korean English as a foreign language (EFL) context. And also the current study examines how GELLs learn English. The authors investigated a total dataset of 83 GELLs from 25 autobiographical books on “How I succeed in learning English as a foreign language.” Results indicated that as GELLs’ language proficiency increased, their L2 motivation changed in different patterns depending on the onset age of active English learning. Second, GELLs preferred metacognitive, cognitive, memorization, and social strategies both at the beginning and advanced stage of the English learning process regardless of the onset age of active learning. Finally, GELLs acquired English through a well-balanced language course regardless of the onset age of active learning. Pedagogical implications and future research suggestions are also discussed.
