한국교통대학교 동아시아연구소에서는 매년 문헌연구를 주제로 하는 국제학술대회를 개최하고 있다. 이번 학술대회는 2019년 9월 28일 한국교통대학교 충주캠퍼스 인문사회관에서 진행되었다. 한중일의 연구자들 참여하여 모두 19편의 논문이 발표 되었으며, 기존 주제의 심화와 새로운 관점의 제시, 학제간 연구의 필요성, 새로이 발견된 자료등 다양한 주제의 발표와 토론이 진행되었다. 특히 이번 학술 대회에는 “국제동아문헌연구학회”의 건립을 위한 한국측 준비위원회(이규갑 · 이강재 · 박영록)의 발의하에 동아문헌연구의 국제적 학회를 건설하기 위한 “준비위원회(籌備委)”를 발족 시켰으며, 준비위원장에는 양주대학 전종무(錢宗武)교수님이 발표회장에 모인 학자들의 만장일치로 추대되었다. 이 기요(紀要 · 綜述)는 양비교수가 2/3 분량에 해당하는 중국 · 일본측 학자의 발표 및 학회의 의의를 기술하고, 박영록교수가 한국어로 진행된 발표의 개요를 첨부하는 형식으로 작성한 것이다. 아울러 본 학술 대회는 “재한중국교사협의회(회장:于鵬성균관대학교 교수)”의 도움을 받았으며, 이 자리를 빌어 감사를 표하는 한편, 앞으로도 두 단체간에 다양한 학술교류가 진행되기를 기대한다.

도로교통 안전성 향상을 위한 사고분석 연구

오주택 韓國交通大學校 2023 한국교통대학교 논문집 Vol.58 No.-

Road traffic safety is the most important area in transportation. Thus, it is necessary to provide continuous interest and researches for the traffic safety area. This study aims to improve traffic safety through the accident modification factors (AMF). The accident modification factors should be based on accident prediction models, which analyze characteristics of road infrastructure and traffics. Rural 4-legged signalized and non-signalized intersections are focused in this study, since they are the most critical area in the road safety. Besides, this study develops the accident modification factors, which can be used to improve the traffic safety for rural 4-legged signalized and non-signalized intersections 도로교통안전은 교통분야의 가장 중요한 분야이며 지속적인 관심과 연구가 필요한 영역이다. 본 연구에서는 도로 의 기능적인 특성 및 교통류의 특성을 고려한 사고예측모형을 개발하고, 이들 사고예측모형들을 기반으로 교통의 안전성 향상에 기여할 수 있는 Accident Modification Factors(AMF) 개발을 연구의 목표로 삼았다. 본 연구에서는 도로의 가장 중요한 부분을 차지하고 있는 기하구조 중 지방부 4지 신호교차로 및 비신호 교차로를 연구의 공간적 범위로 설정하였고, 도로교통의 안전성에 영향을 미칠 수 있는 주요 설명변수들을 찾아내고 이 변수들의 AMF 값 을 제시한다

오주택 韓國交通大學校 2013 한국교통대학교 논문집 Vol.48 No.-

교통의 주요 상충지점인 교차로의 교통사고는 도로구간의 감소추세와 다르게 증가추세를 보이고 있다. 따라서 교차로 교통사고 감소를 위하여 교차로 안전도 분석을 통해 사고의 원인을 파악하고 교통사고를 예측을 통해서 원인과 예방차원에서의 해결방안에 기여하고자 한다. 따라서 본 연구에서는 기존의 교통사고 예측모형에서 주로 사용하는 비선형 회귀방법이 아닌 신경망 모형을 통해 모형을 개발하였다. 수집된 여러 설명변수들 간의 공선성 문제를 분석하였고, 신경망에 많은 설정, 개발 방법 중 어떠한 방법으로 교통사고예측 모형을 개발하는 것이 바람직한지 파악하기 위하여 상관분석을 통하여 총 33개의 변수 중에서 주도로 차로수, 부도로 차로수, 부도로 우회전 차로수, 주도로 횡단보도 유무, 주도로 제한속도, 부도로 제한속도, 부도로 교통섬 유무, 부도로 교통량, 8개의 변수가 사고에 영향을 미치는데 유의미하게 분석되었다. 본 연구에서는 활성화 함수는 가장 많이 사용되는 쌍곡탄젠트와 시그모이드 함수를 사용하였다. 연구 결과, 은닉층이 2개이며 1층은 9개의 노드, 2층은 12개의 노드, 활성화함수는 입력층에는 시그모이드 함수, 출력층에는 쌍곡탄젠트를 사용한 신경망 모형이 가장 높은 설명력(87.7%)을 가진 것으로 분석되었다.

KS Q ISO 3951-1:2013 샘플링 검사에 관한 소고

김광수 韓國交通大學校 2022 한국교통대학교 논문집 Vol.57 No.-

Sampling inspection by variables is being used in inspections that reduce the number of inspections and are expensive, such as destructive inspection. KS Q ISO 3951-1:2013 sampling procedures for inspection by variables for percent nonconforming is an acceptance quality limit (AQL) type sampling scheme. KS Q ISO 3951-1 is supplemented with KS Q ISO 2859-1, and the same terminology and switching rules are used. In this paper, we discuss theoretical considerations for continuous sampling and strictly switching rules. In addition, the methodology is discussed through case analysis so that it can be easily applied in practice.

In holographic dark energy models, the problem of circular logic is examined between the introduction of future event horizon and the accelerating expansion of the present universe. The problem can be divided into two parts, the causality problem of the equation of motion and the circular logic on the use of the future event horizon. The origin of the problem is identified to be a constant bearing future information. We isolate it from causal equation of motion. Then, the constant is shown to be determined from the initial data of the universe.

朝鮮時代 上流住宅의 構成樣式과 體系에 關한 硏究 (忠南, 大田 地域을 中心으로)

박석현 韓國交通大學校 2013 한국교통대학교 논문집 Vol.48 No.-

The results are as follows : 1.Arrangement Element The arrangement element was decided how a main building, the attached building, and yard are located. Spaces for a servants' quarter, a separate house and a shrine were appendixed in a main building. The arrangement style of a building was affected by local faith, social economic, cultural and geographical conditions. The order of arrangement constitution was decided by the function and use of a building, distinction by the sexes, and status system. A class of a building was decided by confucian ideas and status. The order of arrangement constitution consists of a shrine house, a separate house, a main house, a detached house, a servants' quater. 2.Plane Elements Everything such as the scale, the floor, and the style of a house was decided by the use, the function and the grade of a house. The resident order was decided by the relation of young or old. The main house and the detached house was not separated after the middle of Choseon dynasty by a house. Which was a high definition plane constitution. Houses were separated for men houses and woman houses, because it was affected by Confucian ideas after the middle of Choseon dynasty.

In this study, game industry promotion policies related to game age rating included in the government’s 'Comprehensive Game Industry Promotion Plan (CGIPP)' are analyzed and policy implications are derived. The implications of the causal map analysis are as follows. First, it is necessary to alleviate the burden of rating process by conducting game evaluation in a way that responds to the checklist. Second, the adequacy of the rating review should be thoroughly verified after the game rating review. To this end, it is necessary to put in efforts to update the checklist and verify the results of the evaluation. Third, it is necessary to support game companies that do not benefit from the policies presented in CGIPP to improve game content or use multiple platforms. Finally, it is necessary to rearrange functions among agencies in charge of game-related tasks. In other words, the ‘Game Rating and Administration Committee’ and the ‘Game Content Rating Board’ should be mainly responsible for updating checklists for rating, post-verification of ratings, and supporting small game companies. In addition, the primary game rating deliberation should be mainly performed by the self-rating companies.

Most of Companies in modern society are seeking various ways to innovate human resource management to compete with domestic companies and improve competitiveness in the global market. Since the 2000s, with the development of IT technology and full-fledged networks, the environment in the external market of companies has changed rapidly, but the internal human resource management structure of companies has not made any significant changes. The worldwide epidemic of COVID-19 has provided an opportunity for rapid changes in the corporate structure of human resource management in terms of external changes in companies and internal human resource management. COVID-19 was a shock big enough to fundamentally change the internal changes of companies. As a result, corporate smart work has emerged as an important alternative to the paradigm shift of organizational members' work environment and human resource management activities. In the COVID-19 situation, each company introduced a smart work system as a way to solve social distancing measures in the form of face-to-face organizations. Currently, many companies are conducting smart work through telecommuting. Telecommuting is recognized as a new management innovation in business activities in that companies and organizational members can facilitate interactive communication beyond time and space through various IT technologies and network infrastructure. In this regard, this study aims to analyze the various achievements occurring in the field of human resource management as companies' telecommuting is in full swing, and to examine the impact and changes of the telecommuting status on individual characteristics and companies. In terms of corporate human resource management, the non-face-to-face paradigm shift of organizational members and the performance of telecommuting and the current status of companies were analyzed. By comprehensively examining the influencing factors that telecommuting has on the individual characteristics of organizational members, we have looked at the basis on which telecommuting can be activated as a positive role for both companies and organizational members.
