This study was conducted to identify the level of empathy and clinical practice stress and the relationship between empathy and clinical practice stress in nursing students. Data were collected from 252 nursing students between 1st September and 31st December 2013. 249 questionnaires were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlation coefficient. The mean scores of empathy level in the subcategories for perspective taking 3.57, fantasy 3.59, empathic concern 3.72 and personal distress 3.15 were above median and the mean score for clinical practice stress 3.03 was above median. Clinical practice stress positively correlated with personal distress on empathy. These findings indicate that there is a need to manage personal distress on empathy for nursing students with high level of personal distress to lessen stress in clinical practice of nursing students.

This study aims to examine how secondary mathematics teachers perceive and how they use constructed-response assessment in their mathematics classrooms. For this purpose, we conducted a survey in Seoul, Inchun, and Gyeonggi-do; 189 teachers participated in the survey. Results from the data analysis suggest as follows: a) the secondary mathematics teachers participated in the survey seem to consider the primary goals of assessment through constructed-response items as evaluating student achievement and the development of students' thinking and creativity; b) the teachers perceive that constructed-response assessment would promote students' mathematical thinking and problem solving skills; c) in general, constructed-response items were included in both performance assessment(less than 20 percent) and paper-and-pencil test(20 to 40 percent); and d) constructed-response items were primarily used as a part of regular examination, rather than as an independent assessment.

본 연구에서는 여대생의 미용성형 경험 실태와 중독성향에 영향을 미치는 요인을 조사하였다. 무작위 표집한 여대생 223명을 대상으로 2014년에 자료 수집하였다. 수집된 자료는 서술적 통계, t-test, ANOVA, logistic regression으로 분석하였다. 연구결과, 102명(45.7%)은 최소 1회 이상의 미용성형 경험이 있었고, 비외과적인 미용성형 경험이 외과적인 미용성형 경험의 비율보다 높았다. 여대생의 성형중독 성향에 유의한 영향을 미친 변수는 과거의 성형 경험과 성형수술 수용성, 외모에 대한 사회문화적 태도, 외모평가였다. 이 변수들의 설명력은 52% (Nagelkerke R2=.52) 였다. 본 연구를 통하여 여대생의 미용성형 경험 현황과 성형중독에 영향을 미치는 개인적, 사회적 요인을 파악하였다. 이제 여대생들에 있어 성형중독은 무시할 수 없는 심각한 사회문화적 문제 중의 하나이다. 연구결과는 이러한 사회문화적 문제를 파악하고 예방하기 위한 근거자료로 사용될 수 있으리라 사료된다.

The present study examined the differences of system and problems of descriptive assessment at the national, district level, and school's levels between Korea and U.S.A. (focused on NCTM perspective). As results, both Korea and U.S.A. showed that their goals for descriptive assessment at the national level pointed out the importance of assessment of process rather than result. In addition, States of U.S.A. demonstrated concrete rubrics and examples to help many school teachers to use easily, while many Districts of Education in Korea presented implementation rate in school in order to give a official direction to teachers.

The complex number system is supposed to introduce first chapter in the first grade of high school. When number system is expanded to complex numbers, the main aim is to understand preservation of algebraic structure with regard to the flow of curriculum and textbook. This research reviewed overall alternative articulation and treatment of textbooks from a logical viewpoint. Two research questions are developed below. First, in the structure of the current curriculum, when we consider student's 'level', how are the alternative articulation and treatment of textbooks in complex unit on a logical point of view? Second, What are more logical alternative articulation and treatment? What alternative articulation and treatment are suitable for a running goal? and what are the improvement which is definitive?

This study analyzes the content validity of descriptive tests developed for elementary schools, in order to acquire basic data to improve them. Various descriptive tests were collected and tested for differences in proportions between two-dimensional classification of educational objectives and the level of behavioral objectives. Results show that the descriptive tests developed by elementary school teachers mainly focused on "knowledge" and "understanding," and that content validity for behavioral levels to be low. Nine elementary school teachers were interviewed to understand the result. From the interviews, we found both internal and external factors that cause low content validity. The main internal factors were teachers' ability to make two-dimensional classification of educational objectives, the teachers' consideration of students' level, item level of difficulty, the ease of scoring, and path dependence. The main external factors were curriculum, parents, and administration. Based on the results, we suggested the factors related to elementary school teachers' PCK of descriptive tests.

Mathematical symbols concisely represent mathematical contents related to terms by describing their mathematical meanings implicitly. All symbols in elementary school mathematics textbooks are stated as to be read so that elementary school students could understand their mathematical meanings. The same is somewhat true as in middle school mathematics textbooks, however it is often the case that some symbols are difficult to be read and understood because their statements are unclear or different. In this study, we analyze problems and suggest implications on teaching and learning mathematics based on the statements and understanding of reading symbols in middle school mathematics textbooks.

본 논문에서는 서술형 수학 문제 풀이 모델의 숫자 대소관계 파악을 위한 명시적 자질추출방식 Explicit Feature Extraction(EFE) Reasoner 모델을 제안한다. 서술형 수학 문제는 자연현상이나 일상에서 벌어지는 사건을 수학적으로 기술한 문제이다. 서술형 수학 문제 풀이를 위해서는 인공지능 모델이 문장에 함축된 논리를 파악하여 수식 또는 답을 도출해야 한다. 때문에 서술형 수학 문제 데이터셋은 인공지능 모델의 언어 이해 및 추론 능력을 평가하는 지표로 활용되고 있다. 기존 연구에서는 문제를 이해할 때 숫자의 대소관계를 파악하지 않고 문제에 등장하는 변수의 논리적인 관계만을 사용하여 수식을 도출한다는 한계점이 존재했다. 본 논문에서는 자연어 이해계열 모델 중 SVAMP 데이터셋에서 가장 높은 성능을 내고 있는 Deductive-Reasoner 모델에 숫자의 대소관계를 파악할 수 있는 방법론인 EFE 를 적용했을 때 RoBERTa-base 에서 1.1%, RoBERTa-large 에서 2.8%의 성능 향상을 얻었다. 이 결과를 통해 자연어 이해 모델이 숫자의 대소관계를 이해하는 것이 정답률 향상에 기여할 수 있음을 확인한다.

This study aimed to identify factors that influence depression in juvenile offenders. A cross-sectional study design was used. The participants were 275 juvenile offenders from D city. The collected data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regression with the SPSS/WIN 20.0 program. Of the participants, 32.4% and 52.0% were in the clinical group for ADHD and depression, respectively. ADHD symptoms and self-esteem were significantly correlated with depression. The final model showed that depression among juvenile offenders was significantly influenced by perceived health status, ADHD symptoms, and self-esteem. These variables accounted for 37% of the variance of depression.

This study is a descriptive research study to determine the mediating effect of anxiety in the relationship between patient care communication and patient satisfaction among hospitalized patients. Data was collected using self-administered questionnaires from October to December 2021. The collected data were analyzed using descriptive statistics, Pearson's correlation coefficient, and hierarchical multiple regression using the SPSS 24.0 program, and the effectiveness of the mediation effect was tested using the Sobel test. As a result of the study, there was a positive correlation between patient care communication and patient satisfaction, and a negative correlation between patient care communication and anxiety. And there was also a negative correlation between patient satisfaction and anxiety. In the relationship between patient care communication and patient satisfaction, anxiety had a partial mediating effect (z=2.93, p<.001), with an explanatory power of 38.4%. In order to improve patient satisfaction based on the results of this study, it is necessary to develop a program that can improve nurses' patient care communication capabilities and reduce patients' anxiety.
