  • 이 연구는 학생들에게 예상과 불일치한 실험 데이터를 제시한 뒤, 학생들이 이 데이터를 어떻게 해석하는가를 알아보는 것이다. P 대학교 대학생을 대상으로, 진자의 주기에 대해서 과학적 개념을 가지고 있는 학생 중, 깡통진자에 물을 넣어가면서 깡통진자의 주기를 측정할 때, 주기가 일정할 것이라고 예상한 학생 45명을 선발하였다. 학생들에게 깡통진자에 물을 넣어가면서 주기를 측정한 데이터를 제시하고, 표에 기록하게하고 그것을 그래프로 그려 자료변환을 하도록 하였다. 검사문항지를 통해 불일치 인식, 데이터에 대한 선뢰, 인지갈등, 개념 변화 및 실험 결과에 대한 가설 등을 조사하였다. 인지 갈등정도를 측정하기 위해 CCLT(Cognitive Conflict Levels Test) 검사문항지를 사용하였다. 일부 학생들은 선개념에 의존하여, 데이터를 실제 데이터가 아니라고 간주하거나 실험 오류로 간주하였다. 불일치 상황을 인식 한 학생들은 그렇지 않은 학생들에 비해 인지갈등 정도가 높았다. 선개념에 대한 신념이 변한 학생들은 불일치 상황을 인식하였고, 신념이 변하지 않은 학생들에 비해 인지갈등 정도가 높았다. 선개념에 대한 신념이 변하지 않은 학생들은 데이터를 실험 오류로 간주하였다.

  • This paper examines the effects of focus types on case ellipsis in Korean. A number of previous studies have suggested that accusative case markers in Korean and Japanese cannot be dropped when the object they mark is contrastively focused (Masunaga, 1988; Yatabe, 1999; Ko, 2000; Lee, 2002). Using experimental evidence, we argue against the view that case ellipsis in Korean is sensitive to the distinction between contrastive vs. non-contrastive focus. An alternative analysis is proposed which accounts for the phenomenon of variable case marking in terms of the interaction between the contrastive strength and the discourse accessibility of focused object NPs. By viewing patterns of case ellipsis as the result of balancing between these two forces, such an analysis can correctly predict the gradient pattern of case ellipsis shown by the three types of focused objects tested in the experiment (contrastive replacing focus, contrastive selecting focus and non-contrastive, informational focus), while at the same time offering an explanation for why subtypes of focus exert distinct influences on case ellipsis.

  • Purpose: The purpose of this study was to provide basic data for developing strategic programs based on 119 emergency medical technicians leadership perception types. Methods: The subjects were thirty six 119 emergency medical technicians working for out-of hospital in Jeollanam-Do, Korea. Data were collected from July 20, 2017 to October 30, 2017. Q sample of 40 statements and P sample of 36 persons using PC QUANL software. Results: Three types of leadership styles were identified from the explanation (71.5% of the variables). The relationship oriented progressive type (the most common), the performance and value oriented type (the second most common), and the experience oriented filed participation type (the third most common).

  • 이 연구에서는 '계절별 낮과 밤의 길이'에 대한 초등 예비교사들의 인식을 규명하기 위하여 수도권 소재 교육대학교 4학년 재학생 30명이 글과 그림으로 설명한 내용을 분석하였다. 주요 연구 결과는 다음과 같다. 첫째, 예비교사들이 글 설명에서 가장 많이 사용한 용어는 남중고도, 자전축, 공전 순으로 나타났으며, 글 설명보다 그림 설명에서 오개념이 많이 드러났다. 둘째, 글과 그림 설명을 종합하여 예비교사들의 인식을 분석함으로써 공전과 관련하여 자전축이 기울어져서 지구와 태양 사이의 거리가 가까워진다거나, 지구의 공전 궤도 반지름 변화에 의해 계절 변화가 생긴다는 등 과학적 오류를 포함하는 설명 유형을 확인하였다. 또한 지구의 자전과 관련하여 계절별 남중고도는 변화하나 태양이 뜨고 지는 위치는 변화하지 않는다는 등의 설명 유형도 나타났으며, 지구의 공전과 자전 모두와 관련하여 과학적 오류를 포함하는 사례도 일부 나타났다. 분석 결과를 바탕으로 과학 지식을 활용하여 특정 현상의 설명 체계를 구성해 보는 경험의 부족, 자연 현상에 대한 관찰 및 관측 경험의 부족, 인지적 갈등을 유발하는 다른 설명 체계에의 노출 부족 등의 문제를 논의하였다. 이상의 논의를 토대로 초등 교사 양성 프로그램의 과학 영역에서 예비교사들의 이해를 제고할 수 있는데 구체적이고 실질적인 도움이 될 수 있기를 기대한다.

  • The purpose of this study was to provide information about exhibits for nuclear energy in science museums. This analysed form and content of exhibits of science museums. The subjects were exhibits of 3 science museums; Seoul science park, Seoul national science museum, Gwachen national science museum. The research results were as follows: First, 3 science museums had similar methods of exhibits and types of explanations because of speciality of theme. 3 science museums had mostly fixed exhibit. Panel was the most types of explanations in 3 science museums. Second, 3 science museums had similar contents of exhibits. They dealt with nuclear power generation and radiation. However, Some parts such as radioactive waste, nuclear fusion generation had different. This study suggests that exhibits for nuclear energy of science museums use a variety of methods and types of explanation. Also, science museums need to increase exhibits for nuclear energy.

  • The purpose of this study was to confirm correlation between elementary school students' VARK Learning styles test and Scientific Communication Skills through VARK questionnaire (version 7.3) for Youngers and Scientific Communication Skills Test. The subjects were 99 in 6th grade students of an elementary school located in Gyeonggi-do, Korea. The results of this study were as follows: 64% of the students had multiple learning styles, but only 36% of the students preferred a single mode of information presentation. Among students had a single mode preference, the aural ("A") was the highest unimodal preference. Among "V(visual)" mode, "A" mode, "R(read/write)" mode, and "K(kinesthetic)" mode, "A" mode was the commonest learning mode which students had. In Scientific Communication Skills Test, students' overall average was 26.19p [scientific explanation type (11.85p), scientific insistence type (14.34p)]. Girls' scores were higher than boys in scientific explanation type, but not in scientific insistence type. The scores by communication forms were Text (5.67p), Number (6.87p), Table (6.15p), and Picture (7.49p). Girls' scores were higher than boys in Text and Picture forms but not in Number and Table forms. In result of correlation analysis (Spearman's rho) between VARK Learning Styles and the types & forms of Scientific Communication Skills, there were common correlation in "Read/write (R) learning style-Scientific insistence type", "Read/write (R) learning style-Grounds of Scientific insistence", "Read/write (R) learning style-Description of Scientific explanation", and "R learning style-Text form".

  • Purpose: The purpose of this study was to examine the usefulness of the Myers-Briggs Type Indicator (MBTI) through a character analysis of a novel and to improve the understanding of various types of people. This study aimed to increase nurses' understanding and empathy regarding the personality of various patients. Methods: This study categorized the characters in the novel Our Happy Time based on MBTI and analyzed their personality characteristics. Results: It is important for nurses to understand that the following types of patients can be identified using the MBTI: those with a concise explanation (ENTP), a modest attitude (ISFJ), an objective response (ENFJ), and a logical response (ENTJ). Conclusion: It is important for nurses to broaden their understanding of various personality types and backgrounds related to the formation of patients' personalities that they encounter in the clinical field via analyses using the MBTI personality types. Furthermore, understanding communication skills can be an important first step in resolving conflicts that occur during peer interactions.

  • The purpose of this study was to compare the pantyhose labels of domestic products which contain fiber content, size spec., care symbol, performance properties with those of foreign-made ones, in order to propose a desirable model of label description for the domestic products. The results were as follows: 1) There were differences in the fiber content and fiber mixture ratio of pantyhose on the label according to the countries. The pantyhoses made in Korea and Japan were described only fiber name on the label, while the pantyhoses made in U.S.A., Taiwan, and England were described fiber name and percent of fiber mixture ratio in detail on the label. 2) Most of the pantyhose size produced and sold in Korea were same Free size, but the products from other countries (U.S.A., England, Japan, Taiwan) were sold in various sizes. 3) There were differences, according to the countries, in the care symbol and related explanation of pantyhose on the label. The pantyhoses made in Korea and Taiwan were described care symbol only on the label, while the pantyhoses made in other countries were described additional explanation for care as well as care symbol on the label. 4) It was known that, unlike Korea, other countries were developing and marketing various types of functional pantyhose. For example, U.S.A. and England were focusing on appearance and comfort aspects of pantyhose, while Japan and Taiwan were focusing to develop functional pantyhose like anti-bacterial and anti-ultraviolet ray pantyhose.
