이 연구의 목적은 제7차 교육과정에 의한 화학I 교과의 목표와 성격에 대한 화학 교사들의 인식을 조사하고, 학습 지도 시 화학 교사들의 학습 내용 선택도와 학습 지도 방식에 대해 조사하여, 화학I 교과가 교육 현장에서 어떻게 운영되고 있는지 알아보고자 한 것이다. 연구를 위하여 40개 고등학교 화학 교사 44명을 대상으로 설문조사를 실시하였다. 연구결과, 화학 교사들은 제7차 교육과정의 화학I 교과의 목표가 화학적 소양을 갖춘 민주 시민의 양성이라고 인식하고 있었으며, 화학I 교과의 목표에 적합한 수업 방식은 실험·실습 수업 혹은 조사 및 토의 수업과 같은 탐구 중심의 수업 방식이라고 인식하고 있었다. 그러나 실제 수업에서는 개념 중심의 수업이 이루어지고 있었으며, 화학 교사에 따라 학습 내용 선택도에 차이가 많았다. 그리고 화학 교사들은 화학I 교과가 화학 학습에 흥미와 호기심을 갖게 하는데 적합하다고 생각하지만 화학 개념을 체계적으로 이해시키기엔 부적당하기 때문에, 화학I 교과의 학습 내용을 개선할 필요가 있다고 생각하고 있었다. 제7차 교육과정에 의한 화학I 교과의 목표에서 탐구 학습을 강조하고 있으므로 탐구 중심의 수업이 이루어질 수 있도록 충분한 교사 연수와 교수-학습 자료의 개발이 필요하며, 교육과정 개정 시에 화학 교사들의 경험이 충분히 반영되어야 한다고 생각된다.

Even if only two ships are encountered, a collision may occur due to the mistaken judgment of the positional relationship. In other words, if an officer does not know a target ship's intention, there is always a risk of collision. In this paper, the experiments are conducted to investigate how the intention affects the action of collision avoidance in cooperative and non-cooperative situations. In non-cooperative situation, each ship chooses a course that minimizes costs based on the current situation. That is, it always performs a selfish selection. In a cooperative situation, the information is exchanged with a target ship and a course is selected based on this information. Each ship uses the Distributed Stochastic Search Algorithm so that a next-intended course can be selected by a certain probability and determines the course. In the experimental method, four virtual ships are set up to analyze the action of collision avoidance. Then, using the actual AIS data of eight ships in the strait of Dover, I compared and analyzed the action of collision avoidance in cooperative and non-cooperative situations. As a result of the experiment, the ships showed smooth trajectories in the cooperative situation, but the ship in the non-cooperative situation made frequent big changes to avoid a collision. In the case of the experiment using four ships, there was no collision in the cooperative situation regardless of the size of the safety domain, but a collision occurred between the ships when the size of the safety domain increased in cases of non-cooperation. In the case of experiments using eight ships, it was found that there are optimal parameters for collision avoidance. Also, it was possible to grasp the variation of the sailing distance and the costs according to the combination of the parameters, and it was confirmed that the setting of the parameters can have a great influence on collision avoidance among ships.

Water hammer pumps can effectively use the water hammer phenomenon for water pumping. They are capable of providing an effective fluid transport method in regions without a well-developed social infrastructure. The results of experiments examining the effect of the geometric form of water hammer pumps by considering their major dimensions have been reported. However, these conventional studies have not fully evaluated pump performance in terms of pump head and flow rate, common measures of pump performance. The authors have focused on the effects on the pump performance of various geometric form factors in water hammer pumps. The previous study examined how the hydrodynamic characteristics was affected by the inner diameter ratio of the drive and lift pipes and the angle of the drive pipe, basic form factors of water hammer pumps. The previous papers also showed that the behavior of water hammer pump operation could be divided into four characteristic phases. The behavior of temporal changes in valve chamber and air chamber pressures according to the air volume in the air chamber located downstream of the lift valve was also clarified in connection with changes in water hammer pump performance. In addition, the effects on water hammer pump performance of the length of the spring attached to the drain valve and the drain pipe angle, form factors around the drain valve, were examined experimentally. This study focuses on the form of the lift valve, a major component of water hammer pumps, and examines the effects of the size of the lift valve opening area on water hammer pump performance. It also clarifies the behavior of flow in the valve chamber during water hammer pump operation.

Urban planning and engineering undergraduate students need to understand the earth physical systems and that how human beings interact with the earth systems to planning and engineering urban area. The eco-friendly or geo-friendly design and planning of an urban area is a critical issue not only for economic benefits but more importantly for the sustainable future of urban life. However, little study has been done dealing with the urban engineering students' understanding of the earth as a system and what pedagogical approach is appropriate to improve their understanding of the earth as a system. This study is to investigate the impact of a purposely designed ESS course on urban engineering students' understanding of the earth as a system and their perceptions about the instructional approaches of the course on their learning competency. This study utilized a mixed-methodology with three main data sources: concept maps, student's perception survey about their learning competency, and course contents. Both the survey and concept maps were analyzed quantitatively as well as qualitatively. The result of this study showed that the urban engineering students' experience of team-based research about the topic they chose based on their own interest had a positive impact on their understanding of the earth as a system and their learning competency. The results of this study suggest that structuring and presenting the earth system contents in the context of engineering students' understanding and their future career be effective not only for the improvement of students' content knowledge but also for the enhancement of their learning competency such as creativity and problem-solving skills in everyday life situation.

Purpose: Although the Advanced Trauma Life Support (ATLS) course is now taught internationally, it has not been implemented in Korea. In recent years, interest has increased in simulation as a teaching tool in the ATLS course. We therefore hypothesized that simulation training would be a useful adjunct to the ATLS course. Methods: We designed a 1-day curriculum that included skill development workstations, expert lectures, trauma patient simulations, and group discussion for general surgery residents. We conducted a survey to evaluate participants' level of understanding of the initial evaluation and treatment of trauma patients, their degree of knowledge and technical improvement, their satisfaction with the learning goals, and their overall satisfaction with the curriculum. We then analyzed the effects before and after the training. Results: Nine residents attended this course. None of the residents initially reported that they could perform a primary survey of trauma patients. The analysis revealed significant improvements after training in the questionnaire areas of "assembly of the team and preparation for resuscitation of a trauma patient" (p=0.008), "performance of a primary survey for trauma patients" (p=0.007), "resuscitative procedures for trauma patients" (p=0.008), "importance of re-evaluation" (p=0.007), "identifying the pitfalls associated with the initial assessment and management" (p=0.007), and "importance of teamwork" (p=0.007). Conclusions: After the ATLS simulation training, all participants showed significant improvements in their understanding of how to manage multiple trauma patients. Therefore, ATLS simulation training for residents will help in the management of trauma patients.

Purpose: The purpose of this study was to investigate the current status of the 3+1 curriculum implementation of nursing college in transition from a three-year to a four-year nursing education system. Method: This study employs a triangulation study including a questionnaire survey and a focus group interview. The data collected from 34 nursing colleges were analyzed using SPSS/WIN 21.0 program and the interview data(9 department chairs of nursing colleges) were analyzed using qualitative content analysis. Results: The important results are as follows; Many colleges applied academic performance as student selection standards. Factors in students' satisfaction are acquiring the bachelor's degree and a lot more relaxed college life. Factors in students' dissatisfaction are anxiety about national nursing exam and absence of college's own specialized programs. Main points of 3+1 course policy making are strengthening character education and core-fundamentals education in nursing. After qualitative contents analysis, three management-related subjects and 7 sub-subjects emerged. Three subjects were the effects of the 3+1 course running, the difficulties in management and how to run the 3+1 course effectively. Conclusion: From the results of this study, we concluded with some practical implications for the 3+1 course running for reformed nursing schools.
