두보(杜甫)의 진주시기(秦州時期) 시에 묘사된 실크로드 고찰(考察)

Qinzhou(秦州) is the present-day Tianshui City(天水市) in Gansu(甘肅) Province, and in the Han(漢)-Tang(唐) Dynasty, it was a major transportation hub on the Silk Road from Chang’an(長安) to the West. In other words, on the way from Chang’an to Lanzhou(蘭州), the entrance to The Hexi Corridor(河西走廊), the city you must pass through was Qinzhou. This paper examines Dufu’s perception of the Silk Road, which was recognized as an East-West cultural exchange route in the future, and the situation at the time by targeting works created by Dufu during the Qinzhou period. For this purpose, the works containing the image of Qinzhou as an important city on the Silk Road during this period were divided into poems describing the appearance of Qinzhou in the midst of war, Qinzhou as the gateway city of the Silk Road, and the historical relics remaining in Qinzhou at that time. Through this, we will examine what Qinzhou, known today as a city along the Silk Road, looked like in the past, and try to infer what it looked like at the time, which was very different from what it is today. In particular, considering Dufu's tendency to create poetry as a ‘Poetry History(詩史), the realistic depiction helped us to infer the past of the Silk Road today.

인간의 이동은 차량이나 기타 운송수단을 이용할 뿐 아니라 자신의 몸에 있는 다리를 이용하여 이동하기도 한다. 이때 교통수단으로써 보행(步行)이란 사람의 다리를 이용하여 공간을 이동하는 가장 기본적인 교통수단이다. 인간은 단거리나 보행자 전용공간에 있어 보행을 이용하여 이동하게 된다. 보행자 전용공간, 예를 들어 역사 내부나 환승 통로에서 이동할 때 주요 교통수단은 보행이다. 엘리베이터나 무빙워크 등 보조수단이 있기는 하나 모두 보행을 바탕으로 이루어진다. 서울의 경우 포화상태인 자동차 통행을 줄이려는 정책으로 지하철이 건설되어와 지금의 지하철 네트워크에 자신의 목적지까지 환승을 통하여 이루어진다. 하지만 지하철 건설에만 열을 올렸을 뿐 역사 내에서 환승이 이루어질 때의 이용객의 행태에 관해서는 연구가 거의 없는 실정이다.
안전관리 요인들이 안전성과에 미치는 영향에 있어서 안전 분위기와 안전문화의 매개효과

본 연구는 지난 10년간 정부의 노력에도 불구하고 산업재해 감소세가 정체되어 있는 현 상황에서중대재해처벌법 제정 등으로 그 어느때보다 산업안전보건 환경이 급변하고 있는 시점에 산업재해 해결을 위한 보다 근본적인 대책을 조직의 안전분위기와 안전문화를 창출하기 위한 방안을 탐색하는 것으로부터 출발한다. 선행연구를 검토한 결과 조직구성원 개개인이 가지고 있는 심리적 안전분위기와 변혁적 안전리더십, 고성과 작업체계, 안전관리관행들이 기업의 안전지향성을 높일 수 있다고 확인하였다. 본 연구는 설계된 기본 연구가설을 기반으로 연구 모델을 설계하고 모델애 도입된 구성개념에 따라 설문조사를 준비하였다. 자료수집을 위해 전국 200개 중소기업을 대상으로 설문조사를 진행하였고, amos27을 이용하여 가설검증을 진행하였다.실증분석을 통하여 얻은 결론은 다음과 같다. 첫째, 개인의 심리적 안전분위기는 안전분위기와 안전문화에 유의한 영향을 미치고 있음이 밝혀졌는데, 안전분위기에는 +영향을 미치고, 안전문화에는 –영향을 미치고 있었다, 둘째, 변혁적 안전리더십은 안전분위기에는 유의한 영향력이 있지만, 안전문화에는 그러하지 않았다. 셋째, 기업들의 안전관리관행은 안전분위기와 안전문화에 유의한 영향을 미치지 않고 있음이 밝혀졌다. 넷째, 고성과 작업체계는 안전분위기에는 +영향력을 가지고 있고, 안전문화에는 –영향력을 가지고 있어 기존의 고성과 작업체계는 안전문화에는 경직성의 유발을 가져오는 영향이 있었다. 다섯째, 안전분위기가 안전문화에는 유의한 영향이 없어, 안전분위기와 안전문화는 상이한 맥락에서 작용하고 있음이 밝혀졌다. A political and administrative approach may be one way to solve the problem of disasters occurring at industrial sites and workplaces, but it is fundamentally necessary to prepare a disaster solution plan for the corporate organization. It is necessary to obtain safety behavior and safety performance through a safety atmosphere and safety culture for fundamental disaster prevention of corporate members. In this context, this study starts from the perspective of exploring ways to create an organizational safety atmosphere and safety culture against disasters and accidents. Previous studies on safety management have focused on the safety atmosphere and safety culture (Griffin and Kanbanoff, 2001), it fails to integrate the constructs related to organizational behavior in which safety behavior is implemented (Neal and Griffin, 2002). Most of the preceding studies suggest measures of safety atmosphere and safety culture or only investigate differences between sons (Flin et al., 2000). In contrast, Neal and Griffin(2002) have a viewpoint of examining the antecedent and consequent factors of safety behavior at work, and examining the relationship between safety behavior and other behaviors and efficiency at work When the various aspects of management play a synergistic effect while taking on each other"s roles, proper safety performance and behavior can be brought about. This study starts from the point of view of enhancing the safety orientation of corporate organizations as a way to systematically solve the current situation in which the decrease in industrial accidents and occupational accidents is stagnant. To create a safety climate and safety culture in a corporate organization, when various management systems introduced by corporate organizations have a safety orientation, The purpose of this study is to test whether it is possible to increase safety behavior and to suggest a plan to increase the actual safety level. This study examines the possibility of each member"s psychological safety atmosphere, transformational leadership, high-performance work system, and safety management practices to enhance the safety orientation of a company by examining previous studies. First, a method to improve safety performance by enhancing safety orientation shown in previous studies is set as a research hypothesis, and a research model is designed based on this. The safety-related factors included in the research model are operationally defined according to the situation, and the questionnaire is written and comprehensively reviewed to complete the questionnaire. To empirically test the research hypothesis designed by this study on the collected data, it is analyzed using the structural equation model. For the analysis, SPSS26 is used for basic analysis, and AMOS27 is used for the analysis of the structural equation model. The conclusions obtained from the empirical analysis of this study are as follows. First, it was found that the psychological safety atmosphere of the individual had a significant effect on the safety atmosphere and safety culture. Second, transformational safety leadership had a significant effect on the safety atmosphere, but not on the safety culture. These results are in line with Litwin and Stringer(1968) that leadership influences organizational climate to achieve results. Third, it was found that the safety management practices of companies did not significantly affect the safety atmosphere and safety culture. Fourth, the high-performance work system had a (+) influence on the safety atmosphere and a (-) influence on the safety culture. Fifth, it was found that the safety atmosphere had no significant effect on the safety culture and that the safety atmosphere and the safety culture were operating in different contexts.
