문학적 전범으로서 ‘唐詩’에 대한 지식의 유통과 확산 — 朝鮮의 唐詩選集 간행과 수용의 역사를 중심으로
최석원 중국어문연구회 2019 中國語文論叢 Vol.0 No.93
This paper aimed to identify the process of distribution and acceptance Tang(唐)’s poems made under certain social conditions of Joseon Dynasty(朝鮮). To achieve the purpose of this study, a collection of Tang poetry(唐詩選集) was made as the object of this study. First of all, this paper comprehensively reviewed the situation of collection of Tang poetry(唐詩選集) publishing in Joseon(朝鮮). This led to the discovery that the majority of the Tang poetry collections(唐詩選集) compiled by the Joseon(朝鮮) literati were not handed down, as they stemmed from their practicality and the purpose of individual literary flavor. This paper is meaningful in that it was able to identify a part of the distribution and spread of knowledge through the publication of the Joseon Dynasty’s Tang poetry collections(唐詩選集). However, most of the collections are not handed down, and the remaining collections are not complete, which is why we cannot confirm their details. Due to such limitations, this paper analyzed only the introduction of the selection. A detailed analysis of poets and works in Tang poetry collections(唐詩選集) is intended to be a later study task.

지하도로 연결로 오르막구간의 감속행태에 따른 승용차 환산계수에 관한 연구

This study aims to calculate the passenger car equivalent (PCE) of heavy vehicles on one-lane exit sections of underground roads. Traffic-flow simulations were performed using the VISSIM software program. The scenarios were designed under varying conditions, including design speeds of 40 and 50 km/h, slope gradients ranging from 3% to 9%, and heavy vehicle proportions between 5% and 40%. The mixed-traffic flow capacity was calculated for each scenario at the threshold levels, and the PCE was estimated based on the two capacity conditions. The results revealed that the PCE decreased at lower design speeds. For slopes less than 6% at a design speed of 40 km/h, and for slopes less than 4% at 50 km/h, the PCE remained consistent across all conditions. Single-lane exit sections are often employed on underground roads because of congestion and structural constraints. However, when heavy vehicles are present in these sections, the overall traffic flow is dictated by the speeds of the heavy vehicles. To address this issue, the implementation of variable or temporary two-lane exit sections has been proposed to enhance traffic flow and capacity.

본 연구에서는 천연산호와 모조산호의 광물학적 보석학적 특징을 비교 분석하여 천연산호와 모조산호를 구별할 수 있는 기초자료를 얻는데 그 목적이 있다. 천연산호와 모조산호의 광물학적, 보석학적 특징을 알아보기 위해 색, 광택, 투명도, 조흔색, 굴절률, 경도, 염산반응, 형광반응, 비중, 편광현미경 관찰, 전자현미경 관찰, 화학분석 및 X선회절 분석 등의 실험을 하였다. 그 결과, 천연산호의 주성분은 CaCO3이고, 방해석 결정구조를 가지고 있으며, 모조산호들은 탄산염 또는 기타 물질에 색소를 넣어 제조하였음을 알 수 있다. 그리고 천연 산호와 모조 산호는 X선 회절 분석에 의해서도 구별되지만 조흔색, 비중, 굴절률, 염산반응, 형광반응 등과 같은 몇몇 간단한 일반적인 실험을 통해서도 서로 비교되어 감정이 가능하다. It is significant to get the base data for the purpose of distinguishing natural coral from imitation coral by comparing about gemmological and mineralogical characters in this study. Color, luster, transparency, streak color, refractive index, hardness, chemical reaction, ultraviolet fluorescence, specific gravity, observation of microscope and XRD analysis were conducted for identification of natural and imitation coral. As a result, natural coral has usually CaCO3 composition and calcite structure. But, it is known that imitation coral impregnate calcic material with pigment. And they were distinguished also from not only XRD analysis but also a few simple experiments like streak color, specific gravity, refractive index, chemical reaction and ultraviolet fluorescence.
