차량 시뮬레이터를 이용한 연속류 도로의 고령운전자 주행특성 분석
이근희,배기목 한국ITS학회 2021 한국ITS학회논문지 Vol.20 No.1
본 연구는 고령운전자 운전특성 파악을 위한 실증적 분석의 일환으로 차량 시뮬레이터를 이용하여 고령운전자의 주행특성을 파악하고자 하였다. 이를 위해 기존연구 고찰에서 고령운 전자의 주행특성 요소를 파악한 후, 시뮬레이션 환경을 구축하고 일반 운전자와의 주행 비교 를 통해 고령자 운전특성을 명확히 도출하고자 하였다. 실험 결과 고령운전자는 주행속도, 운 전조작(브레이크, 스로틀, 스티어링 작동) 등 차로편측을 제외한 모든 항목에서 일반 운전자와 는 다른 주행특성을 보이는 사실을 확인하였으며, 주요 특성으로 차로변경 시 속도유지 및 적 정 차간간격 확보가 어렵고, 돌발 상황 발생 시 정지거리와 소요시간이 더 많이 필요한 것으로 확인되었다. 결과적으로 고령운전자 주행거동의 일의적 특성을 입증할 수 있었고, 도로설계, 고령자 관련 교통정책 수립 등에 유효한 지침을 제공할 수 있을 것으로 기대된다. vehicle simulator as part of an empirical analysis the driving characteristics of elderly drivers. To this end, the driving characteristics of the elderly driver from previous study review. he driving characteristics of the elderly the driving elderly driver and general driverIn summarizing these experimental results, the -test showed different driving characteristics from general drivers in all items except for one side of the lane, such as driving speed and driving operation (brake, throttle, steering operation) at a significance level of 95%. Second, when changing lanes, it was difficult for elderly driver to maintain speed and secure an appropriate distance between carslderly driver changed lanes even in inappropriate situations (short distances between cars). Third, in unexpected situation, elderly drivers needed more distance and time.

Historically, the appropriate translation of linguistic and cultural differences between texts has demanded great efforts. To improve understanding of different translation practices, in 1813, Friedrich Schleiermacher grouped various translation methods into two categories: domesticating and foreignizing methods. Lawrence Venuti further asserted that domestication produces transparent and fluent language, minimizing foreignness in the source text for the target reader. Based on this assertion, translators have traditionally classified domesticating translations as those that show strangeness in the source text. According to the present study, however, translators may use domestication not only when there are exotic elements but also when foreign elements are absent in the source. Therefore, this study defines domesticating translation as using the distinctive aspects of the target language and culture, regardless of foreignness in the original text.

초임계수 산화조건에서 Dihydrobenzenes의 분해에 미치는 NaOH의 첨가효과
이근희,김종국 한국화학공학회 2002 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.40 No.5
초임계수와 초임계수산화법에서 catechol과 hydroquinone의 분해에 미치는 NaOH 첨가효과에 대하여 검토하였다. 초임계수 및 초임계수산화법에서 NaOH를 첨가한 경우와 첨가하지 않은 경우의 4가지 조건에서 실험을 수행한 결과 NaOH 첨가는 catechol과 hydroquinone의 분해를 촉진시키는 것으로 나타났다. GC/MS 분석결과 catechol과 hydroquinone의 초임계수산화로부터 많은 중간생성물이 확인되었다. 특히 많은 양의 1,4-benzoquinone이 hydroquinone의 초임계수산화로부터 검출되었다. 1,4-Benzoquinone은 hydroquinone의 산화 후 CO_2까지 진행하는 것을 방해하는 억제자로 알려진 물질이다. Catechol과 hydroquinone의 초임계수산화에서 NaOH 첨가는 1,4-benzoquinone를 포함한 다양한 중간생성물의 분해를 촉진시켰으며 NaOH 첨가는 초임계수 및 초임계수산화법에서 CO_2과 CH_4의 생성량을 증가시켰다. 이러한 결과는 catechol과 hydroquinone의 초임계수산화에서 NaOH가 반응에 상당한 영향을 미치는 것으로써 보다 실용적인 초임계수산화공정의 반응기설계나 최적운전조건의 선정을 위해서는 NaOH 첨가효과를 고려하는 것이 필요한 것으로 판단되었다. The aim of this study is to compare the effects of NaOH addition in the decomposition of dihydrobenzenes(catechol and hydroquinone) using supercritical water(SCW) and supercritical water oxidation(SCWO) conditions. Experiments were performed using four sets of conditions, which were in the presence and absence of NaOH in both SCW and SCWO conditions. Under the experimental conditions, the addition of NaOH accelerated the decomposition of catechol and hydroquinone in both the conditions. Several intermediates were identified by performing GC/MS analysis from SCWO of catechol and hydroquinone, and in particular, a large quantity of 1,4-benzoquinone were detected from SCWO of hydroquinone, which is known as an probable inhibitor to hinder the production of CO_2 after hydroquinone oxidation. The addition of NaOH to catechol and hydroquinone oxidation reduced the generation of these intermediates including 1,4-benzoquinone, however the effects of the NaOH addition in SCW were the similar as compare to those of SCWO. Further, the addition of NaOH increased the production of CO_2 and CH_4 in both the conditions. These results revealed that the effects of NaOH on the decomposition of catechol and hydroquinone using SCWO are not negligible. Therefore, its effects on the decomposition of other organic compounds under SCWO conditions should be estimated for determining optimized operating conditions and reactor designs.
