Information gathered through experience transforms into knowledge and such knowledge becomes a foundation for intuitive decisions. Based on such background, the following study investigates intuitive decision making on basic elements needed for design concepts and visual conceptualizations. The study consist two phases. first, 12 structural elements of a digital camera and relation between each elements were arranged intuitively on a board. Next, sketches were generated with relationship of structural elements in mind. As a result of the study, concept with intuitive decisions effect structural thinking, various developments, specific operation methods , and sketch expressions. However, study also revealed that the freedom of human emotions don't accord with the qualification map.

The present paper investigates about the formation of the logical thinking and the intuitive thinking in mathematical concepts with reference to secondary talented students (students aged 16$\sim$17 years). As a main result, we conclude that their preference between the logical and the intuitive thinking does not related to the distinction of the school level and sex, while their consistence between them relates.

Self-induction is an important concept in the field of electromagnetism, which is dealt with in all the high school physics textbooks. According to the results of the survey on self-induction, most of general high school students and even science high school students have overgeneralized concepts that high self-induced emf. are produced whenever the switch is turned off in the circuit containing inductors. The reasons of this overgeneralization on self-induction could be explained through the analysis of current high school physics II textbooks. Main reasons can be attributed to the fact that, by depending on their intuitive ideas, students try to vaguely explain the concept, based on lighting up of Ne tube in the special circuit. This study found out qualitative method to have students effectively understand self-induction based on quantitative interpretation to gain scientific understanding on self-induction.

This study aimed to identify the factors influencing the clinical competence of nurses, using a descriptive correlational study design. Data were collected through questionnaires administered to 170 nurses working in a general hospital in Gwangju city and Jeollanam-do province from March 24 to May 27, 2021. There were significant differences in clinical competence according to age, marital status, and educational level. Clinical competence was significantly correlated with nursing professionalism (r=.600, p<.001), critical-thinking disposition (r=.568, p<.001), communication skills (r=.658, p<.001), and nursing practice environment (r=.353, p<.001). Factors influencing clinical competence were communication skills, nursing professionalism, critical-thinking disposition, and age, which explained 54.0% of the total variance. It is necessary to develop educational programs to improve the communication skills, nursing professionalism, and critical-thinking disposition of nurses. Additionally, Institutional and national measures are needed so that nurses can continue to work in hospitals.

최근 해양사고에 따른 피해가 늘어남에 따라 선박의 안전항해에 대한 관심이 높아지고 있으며, 해양사고에 대한 규제 및 사고방지를 위한 기술의 개발도 활발하게 진행되고 있다. 이러한 요구에 따라 IT 기술들을 적용한 다양한 항해장비들이 개발되어 항해사의 안전운항을 지원하고 있지만, 다양하고 많은 정보를 무분별하게 제공하기 보다는 정보를 표시하고 서비스하는 효율적인 방법에 대한 연구가 더욱 필요한 실정이다. 효율적인 항해 장비는 항해사가 의사 결정을 신속하고 정확하게 내릴 수 있도록 보다 단순하고 직관적인 방법으로 정보를 표시할 수 있어야 하며, 본 논문에서는 선교에서 활용될 수 있는 증강현실 항해지원 시스템의 설계 및 구현에 대해 기술하고자 한다. 본문에서는 시스템을 카메라를 기반으로 하는 하드웨어 모듈과 실시간으로 증강영상을 생성하는 소프트웨어 모듈로 구분하여 설명하며, 선박운항 시뮬레이터를 이용한 시작품의 시험 평가 방법에 대해서도 언급한다. 이러한 증강현실 기반의 항해지원 시스템은 사고방지 및 운항효율 증대에 기여할 것으로 기대한다.

통계는 연역적 사고를 강조하는 수학의 다른 영역과 달리 귀납적 추론과 직관적 사고를 요구한다. 따라서 학교 수업에서 학생들이 실제적인 상황을 모델링 할 수 있도록 하며, 주어진 상황에서 자료를 올바르게 산출하고 분석 할 수 있도록 적절한 지도 방법이 필요하다. 그렇지만 학교 수업은 대다수 알고리즘 연습 위주의 통계 학습-지도로 통계적 사고 교육이 제대로 이루어지지 못하고 있다. 이로 인해 학생들은 형식적인 통계 처리에는 익숙하지만 통계 교육의 궁극적 목적인 변이성과 자료를 현명하게 다루는 능력이 부족하다. 본고에서는 피상적인 기계적 계산위주의 통계교육에서 실제적인 자료를 수집하고, 이를 적절히 가공 처리하여 정보의 가치를 높일 수 있는 통계 지도 방향을 탐색해 보고자 한다.

The purpose of this study is to confirm the effect of simulation practice education applied to nursing students on communication competency, critical thinking tendencies, and professionalism. This study is a one-group pre-post test design-like experimental design study, and 89 fourth graders of the Department of Nursing at one university were targeted. Data collection was from September to December 2019. The collected data were analyzed through frequency and percentage, mean, standard deviation, paired t-test, and Pearson correlation using the SPSS 20.1 program. As a result of the study, the subject's communication competency after simulation practice training (t=3.41, p<.001), critical thinking tendency (t=2.75, p<.007), professionalism was found to have increased statistically significantly (t=2.56, p<.012). After simulation practice, it was found that communication competency, critical thinking tendencies, and professionalism each had a positive correlation.

As intuition is more unreliable than logic or reason, its studies in mathematics and mathematics education have not been done that much. But it has played an important role in the invention and development of mathematics with logic. So, it is necessary to recognize and explore the value of intuition in mathematics education. In this paper, I investigate the function and role of intuition in terms of mathematical learning and problem solving. Especially, I discuss the positive and negative aspects of intuition with its characters. The intuitive acceptance is decided by self-evidence and confidence. In relation to the intuitive acceptance, it is discussed about the pedagogical problems and the role of intuitive thinking in terms of creative problem solving perspectives. Intuition is recognized as an innate ability that all people have. So, we have to concentrate on the mathematics education via intuition and the complementary between intuition and logic. For further research, I suggest the studies for the mathematics education via intuition for students' mathematical development.

Multi-car rear-end collision accidents have three categories: sequential collision from the rear which is commonly referred to as chain reaction collision, sequential collision from the front, and mixed-order collision. This paper suggests several effective methods of reconstruction analysis for multi-car rear-end collision accidents. First, by incorporating the traditional empirical method which uses vehicle damage caused by brake dive and passenger injuries, with results of theoretical analysis made within mechanics of rigid body, it is made possible for the method to be put to immediate practical use. A methodology to precisely analyze multi-car rear-end collision accidents was suggested using a simulation program simultaneously with a video event data recorder which is starting to be widely used in domestic vehicles. To go beyond the simple intuitive analysis of the video event data recorder, the simulation analysis based on the results of video analysis was executed to acquire various information, so that the causes and responsibility could be clearly stated.
