본 연구의 목적은 신호교차로의 적정황색신호시간 산정을 위한 것으로, 황색신호시간 산정 시 접근속도와 교차로 폭에 따른 연관성을 알아보고 신호 운영에 따라 변화되는 교차로 내 상충과 딜레마구간을 최소화하여 교차로 운영 안전성을 확보하는 데 있다. 이를 위해 5개 교차로의 6824건의 자료를 수집 분석하였다. 주요 연구결과는 첫째, 차로별 개별차량 접근속도를 분석하고 방향별 상충을 고려해 교차로 폭을 정의하였다. 둘째, 기존 산식의 문제점을 보완한 접근속도와 상충 지점 기반 다중회귀모형식을 개발하였다. 셋째, 개발 산정식을 통해 접근속도와 교차로 폭에 따른 적정황색신호시간 적용 기준표를 제시하였으며, 와의 관계를 이용해 황색신호시간과 딜레마구간을 교차 분석할 수 있는 산정표를 제시하여 황색신호시간 변화에 따른 딜레마 길이의 안전성을 판단하는 방안을 제시하였다.

Objective: This study examined the code of ethics, which offers guidelines for early childhood teachers' ethical decisions and practices. Results and Conclusion: In the second section of this paper, the meaning of the code of ethics is reviewed. The issues of the code of ethics are also investigated to resolve moral and ethical dilemmas and to maintain high standards of professional conduct in early childhood care and education. In the third section of this paper, a comparison of the ethical codes in South Korea, Japan, the United Kingdom, and the United States is conducted. Based on the results raised in relation to the code of ethics principles and the results of comparing domestic and international ethics codes, the fourth section of this paper focuses on three topics in the current and future direction of the Korean code of ethics: (a) concreteness and clarity, (b) switching from the viewpoint of least harm to the viewpoint of maximum benefit, and (c) the range of benefits of the code of ethics. Then, including the existence of the last two codes of ethics, we discuss the direction of future difficulties currently associated with the situation in Korea.

The purpose of this study is to trace historical changes and to show broad spectrums in landscape architectural drawing. Drawing has been both a locus of interpreting a site and a vehicle of imagining the new landscape. The designed landscape might be influenced by the way to draw in landscape design. Despite of its importance, landscape architectural drawing has rarely been discussed. Here, the drawing will be understood as theoretical issues and texts for criticism. Recently, the drawing has primarily been recognized in functional and instrumental ways. The stereotypes office drawings such as plan, section, perspective, axonometric are typical examples. Its symbolic and metaphoric dimensions have been seriously diminished. As a result, the poetic power in the designed landscape might be devastated. Composite drawing, notation are the alternative drawings to overcome the above mentioned dilemma along with the adaption of collage and photomontage. Finally, I would argue that landscape architectural drawing can be a creative tool to elicit the idea and to reveal the trace of memory. It could be also a poetic locus to postulating the vision. Designers should utilize both traditional drawing and experimental drawing in order to reconcile the instrumental representation with the symbolic representation.
