함수적 사고는 수학적 문제 해결에 있어 기본적인 사고이다. 함수적 사고에서는 변수 사이의 종속성 파악이 그 핵심이 된다. 이는 DGS 동적 기하의 동적(변화), 종속적(구성)이라는 특성에 잘 부합한다. 이에 우리는 동적 기하 환경에서 타당한 종속성 부여를 통해 primitive한 생성자를 알아보고, 이들의 조작과 역 조작, 합성 조작하는 과정을 통해 함수적 사고에 접근하는 방법을 연구해 보려 한다. 나아가 자취 기능을 이용함으로써 시각화를 통해 종속적 관계를 표현해 보고자 한다. 이것은 MicroWorld 환경에서 학습자가 스스로 대상을 구성하는 경험을 통해 함수적 사고를 자연스럽게 형성하도록 하는 것이 바람직하다는 관점에 바탕을 두고 있다.

정부는 '11. 12월 준해양사고 통보제도를 도입하고 주요 사례를 분석, 교육을 도출하여 업계에 전파하여 해양사고 예방에 기여하고 있다. 그러나 통보제도는 자율로 시행되고 있어, 대상자가 준해양사고를 통보하지 않으면 준해양사고 발생 여부를 확인할 수 없다. 그러므로 제도는 자발적인 참여에 의존할 수 밖에 없다. 본 연구는 능동적인 해양사고 예방을 위하여, 해양사고 중 충돌사고를 대상으로 준해양사고와 해양사고 간 상관관계를 도출하고 이를 실해역에 적용, 검증하고자 한다. 연구 결과는 해양사고 건수 및 발생 장소를 예측하고 업계에 전파 할 수 있는 기초자료로 사용될 수 있다.

Purpose: The purpose of this study was to identify critical thinking disposition, clinical performance, and satisfaction of clinical practice in a college nursing students. Methods: The data were collected from self reported questionnaires about clinical performance, and critical thinking disposition given to 55 nursing students at June, 2017. Results: The mean score of total clinical performance was 3.70 (${\pm}.54$). Total critical thinking disposition was 3.57 (${\pm}.44$) and clinical satisfaction was 3.93 (${\pm}.72$). Regarding clinical performance, psycho-social competence was highest followed by basic care competence, educational care competence, nursing process competence, observing and monitoring competence, and nursing intervention competence. Critical thinking disposition had a significant positive correlation with clinical competence. Conclusion: Results of this study suggest that developing various clinical education and teaching learning methods for clinical competence is necessary to promote critical thinking disposition of nursing students.

This study was conducted to identify the factors affecting the communication competency in nursing students. Method: The subjects of this study were 171 nursing students from two universities located in G and P cities. The collected data were analyzed by t-test, ANOVA, Pearson's Correlation Coefficient, and Multiple Regression Analysis. Results: As a result of multiple regression analysis, the significant predictors of communication competency of nursing students were interpersonal relationships(β=.404, p<.001) and positive thinking(β=.274, p=.014). Communication competency was explained 47.9% of variance in interpersonal relationship and positive thinking. Conclusion: The results of this study showed that interpersonal relationship and positive thinking in nursing students were the influential factor on communication competency. Therefore, the results of this study suggest that it is necessary to find ways to improve interpersonal relationship and positive thinking in order to improve communication competency of nursing students, and it is considered to be useful as basic data for developing intervention programs to improve communication competency.

This study was done to identify the relationship among smartphone addiction, emotional intelligence, critical thinking disposition and communication skill for nursing students. Subjects were 301 associate nursing students in Korea. The data were collected using self -report questionnaire from november 1 to november 30, 2016. Data were analyzed by frequencies, t-test, ANOVA, Pearson's correlation using SPSS Win 18.0. The score for Smartphone addiction was 2.84. Tolerance was the highest and Virtual world orientation was the lowest in the subdimension. 88.7% of the general user group, 9.6% of the potential risk user group and 1.7% of the high risk user group were in the order of the smartphone addiction. Smartphone addiction were significantly negative correlation with emotional intelligence and critical thinking disposition in nursing students. And the higher smartphone addiction was showed the lower emotional intelligence, critical thinking disposition. Smartphone addiction were no significantly correlation with communication skill in nursing students. Emotional intelligence were significantly positive correlation with critical thinking disposition and communication skill in nursing students. Therefore, To increase emotional intelligence and critical thinking disposition of nursing students, it is necessary to develop and test the program for decrease smartphone addiction of nursing students.

This study was intended to validate and develop the driving stress coping behavior scale. In a preliminary investigation, literature studies on the driving stress and open questionnaire were administered and examined in four regions in Korea. As a result, 64 items driving stress questionnaire were developed. In the study, this Driving Stress Coping Behavior Scale(DS-CBS) was examined to 372 drivers located seven regions in Korea. The factors analysis revealed 2 meaningful factors[(Good Coping: GC), (Bad Coping: BC) with 24 items. When internal consistency for each 2 factor was calculated, all sub-scale revealed a satisfactory level of Cronbach's α. Also, correlations with Driver Coping Questionnaire(DCQ) and risk driving behaviors(speed driving, drunken driving, traffic violation, offence accident, defence accident) supported consistently validity of the Driving Stress Coping Behavior Scale(DS-CBS). Also, We investigated the influences of 'Good Coping', 'Bad Coping' consisting of driving stress coping behavior, on traffic accidents risk. As a result, 'Good Coping' and 'Bad Coping' influenced traffic accidents risk. 'Good Coping' had decreased effects, the other side 'Bad Coping' had increased effects on traffic accidents risk(TARI).

This study is a descriptive correlation study investigating the effects of stress disorder symptoms, resilience, and social network on post-traumatic growth in traffic accident patients. The participants were 158 traffic accident cases enrolled from five 100-bed hospitals situated in city C. Data were collected from July 1 to August 31, 2018, and analyzed by t-test, ANOVA, Pearson's correlation coefficients, and multiple regression using SPSS / Win23. The explanatory power of post-traumatic growth was determined to be 36.9%, and the factors affecting post-traumatic growth were social network and post-traumatic stress disorder. In addition, social networks completely established the relationship between resilience and post-traumatic growth. Our results confirmed that a wider social network and increased symptoms of post-traumatic stress disorder of the traffic accident patient are associated with higher post-traumatic growth. Therefore, it is necessary to explore approaches that improve the social networks and resilience to help post-traumatic growth of traffic accident patients. Additional research is required through repetitive and long-term observation of the accident victims.

SRK-BB(Skill-, Rule-, Knowledge-Based Behavior)는 주어진 사건을 처리할 때 인간이 행하는 행동을 체계적으로 식별하기 위한 하나의 이론이다. 이러한 SRK-BB에 대한 결과는 주어진 임무에 대한 '성공'과 '실패'로 나타낼 수 있다. 만약, 어느 사건에 대한 SRK-BB를 식별할 수 있고, 이에 대한 '성공/실패'의 결과를 알 수 있다면, SRK-BB를 이용하여 이들 사이에 연계된 확률적인 관계를 정립할 수 있다. 한편, 해양사고의 결과를 분석한 해양안전심판원의 재결서 또는 재결요약서에는 다양한 사고(즉, 실패한 사건)에 대해서 해기사가 어떠한 행동을 취했는지 상세하게 기록되어 있다. 이러한 해양안전심판원의 자료를 분석하면 실패한 해양사고에 대한 방대한 해기사의 SRK 분포를 확보할 수 있다. 본 연구의 목적은 다양한 해양사고에 나타난 해기사들의 행동을 SRK-BB로 식별한 후 해기사들이 추후 야기할 수 있는 인적오류를 예측하기 위한 모델 구축에 있다. 인적오류 모델을 구축하기 위해서는 우선 해양사고에 포함된 SRK 분포 분석이 필요하고, 시스템적인 입출력 관계를 통해서 SRK에 의한 인적오류의 결과를 예측하기 위한 예측 모델이 필요하다. 본 연구에서는 해기사의 인적오류에 의한 사고를 어떻게 SRK 분포를 이용하여 예측할 수 있는지에 대한 개념을 설명하고, 해양사고 데이터에서 획득한 SRK 분포의 의미와, SRK 분포를 이용하여 어떻게 해기사가 야기할 사고를 예측할 수 있는지에 대한 연구접근 방법을 소개하고자 한다.

Fatalities from traffic accidents constitute one of the major health issues as well as safety ones in Korea. It has been reported that traffic accident is affected by the combined effects of road. vehicle. and human factors. Over the past few decades, a number of studies have been conducted to find the impact of road geometric factors on traffic safety. The purpose of this study is to investigate the effect of road geometric factors on traffic safety on Korean expressways. Detailed geometric design data were available from Korea Highway Corporation. Five-year traffic accident data on Honam expressway were collected and analyzed. It was found that following geometric factors influence traffic safety on expressways : radius of curve, curve length, and length of straight section. Furthermore, the existence of I.C. turned out to have a significant impact on traffic safety level. Based on the data analysis several multiple regression forms that relate traffic accident frequencies and geometric factors on expressways are developed.
