본 연구에서는 비슬산 강우레이더 관측반경 내 표준유역별 정규화오차 정확도를 이용하여 강우량, 유역특성 등 강우레이더 관측의 수문학적 평가요소와의 상관 특성을 분석하였다. 이를 분석하면 강우레이더 관측 오차 또는 정확도가 수문학적 특성에 따라 얼마나, 어떻게 발생하는지를 추정할 수 있고, 이를 이용하여 홍수예보에 활용되는 입력 자료의 오차를 유역단위로 명확히 정량화 할 수 있어 보다 정확하고 신뢰도 높은 홍수예보에 도움이 될 것으로 기대된다. 강수량 크기와 강수추정 정확도 간의 상관 특성을 분석하기 위해 표준유역 평균 최대 강수량과 강수추정 정확도 간의 분포특성을 분석하였다. 단기간의 자료를 분석하여 오차특성을 정규화 하기는 매우 어렵기 때문에 본 연구에서는 비슬산 강우레이더로 관측된 2012년에서 2016년(5년)사이의 236개 강우사상에 대하여, 동기간의 기상청 AWS 지점 강우량을 기준으로 비슬산 강우레이더의 정규화오차 정확도(1-NE)를 산정한 후 이를 이용하여 850개 표준유역 별 유역평균 정규화오차 정확도를 재산정 하였다. 분석결과 표준유역 평균 최대강수량과 정규화오차 정확도 간에는 유의한 상관성이 있는 것으로 나타났다. 표준유역 평균 최대강수량의 크기에 따라 정규화오차 정확도가 상대적으로 일정한 경향이 나타났고 후처리 단계에서의 편파변수 최적화 이후에는 레이더 강수추정의 정규화오차 정확도가 표준유역 평균 최대강수량 크기에 상관없이 일정해 지는 것으로 나타났다. 따라서 이러한 일정한 레이더 강수추정의 정규화오차 정확도는, 편파변수 최적화에 의해 관측 가능한 최대 기대 정확도 수준 도달에 도달했다고 볼 수 있으며, 표준유역에서 강우레이더의 강수추정 기대 정확도 수준은 84%(정규화오차 16%에 해당) 정도로 추정되었다.

This study was conducted to investigate the impact of emotional intelligence according to the level of interpersonal relation competence. For the study, data were collected from 126 students in the department of nursing at a university located in B city from November 29 to December 16, 2019, and data were analyzed by Anova and Regression analysis. The interpersonal relation competence of nursing students was classified into less than 60 and 60 or more. In the group with an average of less than 60 in interpersonal relation competence. nursing students' self-emotional expression and control of others were significant positive effecting factors for interpersonal relation competence(explanatory power, 22.5%). In the group with an average of 60 or more in interpersonal relationship competence, self-emotional expression and Motivation were significant effecting factors(explanatory power 33.6%). According to the results of this study, we propose an individual approach according to their level of interpersonal relation competence for nursing education to improve the interpersonal relation competence abilities of nursing students.

Academic engagement has been known as a strong predictor of students' cognitive and affective outcomes in an educational context. Despite increasing interest and theoretical usefulness of this construct, a few researchers seem to be interested in the validation of instruments to measure academic engagement for Korean students. Thus, this study would like to introduce one of academic scales widely used, UWES-S(Utrecht Work Engagement Scale-Student) (Schaufeli et al., 2002a: 2002b) and to validate the UWES-S for Korean college students. To validate the Korean version of the UWES-S, 651 college students (285 for Field Trial, 366 for Main Study) were used. The procedure is as follows. First, we used an integrated adaptation procedure to produce a Korean version of the UWES-S. Second, EFA(exploratory factor analyses) was applied to explore the factor structure of the UWES-S on the field trial data. Third, the psychometric properties of the UWES-S items were examined by graded response model(GRM). Also CFA(confirmatory factor analysis) was used to examine its internal construct validity for the data from the main study. Finally, the external validity of the UWES-S was scrutinized with the related variables such as academic motivation and satisfaction. As a result, the Korean version of the UWES-S with 13 items was accepted that the four items were excluded from its original version. Second, the internal validity was supported that the 3 factor CFA model(vigor, dedication, absorption) fit the data well. Third, we supported the partial mediation model that academic engagement played as a mediating variable between academic motivation(internal/external) and academic satisfaction. Finally, the differences between a validation of UWES-S for Korean college and high school students, the necessity of construct equivalence testing, and direction for future research of scale validating were discussed.

The purpose of this study is to develop a rhythm-based music intervention protocol to enhance timing regulation in children with ADHD and investigate its feasibility. For this purpose, a three-phase study was conducted involving ADHD children and typically developing children. In the first phase, group-specific baseline measurements were taken for auditory attention (KAT), motor timing, and perceptual timing. In the second phase, a rhythm-based music intervention protocol incorporating key factors was developed. In the third phase, the developed protocol was applied to ADHD children to investigate the variables affecting timing regulation and to verify its effectiveness. Results from the first phase revealed significant differences in the timing values of children with ADHD, particularly in tasks requiring discrimination of sound duration and precision in rhythm patterns. Additionally, exploratory factor analysis of KAT results and motor/perceptual timing identified three clusters: attentional responsiveness, attentional synchronization, and attentional sophistication. In the second phase, a protocol consisting of tasks involving synchronization, attentional shifting, and rhythm production at various difficulty levels was developed and validated for expert validity. In the third phase, individual application of the protocol to children with predominantly inattentive and hyperactive-impulsive ADHD subtypes demonstrated changes in timing regulation tasks. This study provided basic data for using rhythm as an effective facilitation tool that leads from voluntary to involuntary attention in children with ADHD.

From the perspectives of grammaticalization and corpus, the purpose of this study is to examine the motivation of the emergence of the split infinitives in American English and to discuss the justification of the split infinitives based on the corpus empirical data such as COHA and COCA. The formerly ungrammatical split infinitives in the form of [to + adverb + verb] are now definitely grammatical forms in Present Day English (PDE). The corpus-based data confirms the legitimacy of the split infinitives with the empirical reasons like clarifying sentences (i.e., disambiguation) or strongly focused readings. In addition, the split infinitives are natural consequences caused by the grammaticalization of an infinitival particle to and most crucially by the loss of verb movement. When verb movement to T position does not occur in infinitival clauses, the word order results in [to + AdvP + V], thus forming the split infinitives. The split infinitives are no longer a matter of discussion and will continue to increase in both formal and informal contexts as being definitely grammatical forms.

This study explores an initial framework for online product categorization by examining the relationships among Internet motivations, buying tendencies, and online purchase intentions for product categories. A total of 217 usable questionnaires were obtained from respondents in a southwestern state in the United States. A path model using a correlation matrix with maximum likelihood was estimated using LISREL 8.53. Findings indicated that Internet motivations consisted of four factors: Diversion, Economic, Information, and Social motivations. In addition, online products were classified into three categories based on purchase intentions: Sensory, Cognitive, and Search products. Estimated path model showed that diversion and economic motivations affected impulse buying tendency, whereas economic, information and social motivations influenced planned buying tendency in the online context. Also, the buying tendencies were significantly related to online purchase intentions for the product categories. Purchase intentions for sensory products were more strongly affected by impulse buying tendency, whereas purchase intentions for cognitive and search products were more strongly affected by planned buying tendency. Theoretical and managerial implications were discussed for devising an appropriate e-market strategy for specific product categories.
