가변안내표지판 메시지 표출형식 및 지체수준 별 운전자 우회율 분석 연구
유수인,김병종,김원규 한국ITS학회 2013 한국ITS학회논문지 Vol.12 No.6
본 연구는 가변안내표지판(VMS, Variable Message Sign)의 표출방식과 제공되는 정보의 지체수준에 따른 운전자 우회율을 분석하는 것이 주요 목적이다. 이를 위하여 20대 이상의 운전면허소지자를 대상으로 차량시뮬레이터를 이용한 가상주행 실험 후 SP 조사를 실시하였고, 조사결과에 대하여 로짓모형을 구축하였다. 분석결과 문자식과 도형식 간 표출형식에 따른 운전자 우회에는 차이가 없었다. 또한 우회도로가 원활상태 일 경우, 주도로의 지체수준 125% 시점에서 우회하기 시작하였고, 지체수준이 증가함에 따라 우회율은 근소하게 증가하는 것으로 나타났다. 우회도로가 지체상태 일 경우, 주도로의 지체수준 125% 시점에서 우회하기 시작하였고, 지체수준이 증가함에 따라 우회율은 지속적으로 증가하는 것으로 나타났다. 본 연구의 결과는 운전자의 우회시점에 대한 기준점을 제시하고 있으며, 향후 교통성능향상을 위한 교통정보제공 전략 수립 시 이를 반영한 교통정보제공전략이 검토·적용 되어야 할 것이다. The main purpose of this study is to analyze the diversion rate by the levels of delay and the types of display. For this study, we developed the logit model by analyzing the result of SP survey of drivers who have driver’s licence after manipulating a virtual driving simulator. The result of analysis was that the types of display was not statistically significant to the diversion rate. On the other hand, the levels of delay was very meaningful factor with the diversion rate. When the main road was flowing smoothly, drivers started to detour at the levels of delay 125% under the traffic free flow state. Similarly, when the levels of delay got worse, the diversion rate kept the same percentage as it was at the levels of delay 125% state which represented a smooth road condition. Likewise, when the main road’s traffic flow was slow, drivers appeared to make detours at the same state of the levels of delay 125%. It was found that as the levels of delay got worse, the diversion rose higher than the diversion rate at the condition of slow traffic flow situation with the levels of delay 125%. The result of this study suggests the criterion of drivers detour point. For the conclusion, the result of study would be a reasonable reference for establishing transportation strategies by reflecting drivers’ detouring property and would improve the efficiency of traffic flow.

This study was conducted to find out the appropriate level of turmeric powder for pound cake. The moisture content, pH, sugar content, chromaticity, texture profiles, antioxidant activity, and quantitative descriptive analysis were examined using the samples in proportions of 0%, 10%, 20%, 30% and 40% by varying the ratio of turmeric powder. Results are as followed. First, the moisture content and pH of pound cakes were found to increase with an increased in the addition of turmeric powder, but there was no significant difference in sugar content between samples. Second, Hunter L value significantly decreased and Hunter a value and b value were increased according to add the turmeric powder. Third, the hardness, cohesiveness, and springiness increased and there was no significant change in adhesion or cohesiveness according to add the turmeric powder. Fourth, DPPH radical scavenging ability increased significantly according to add turmeric powder in the antioxidant activity. Based on these results, current study found that the level of addition that can minimize the effect of the flavor of turmeric was confirmed through the evaluation of the sensory characteristics. Therefore, this founding will contribute to develop the formulation of pound cake according to add the turmeric powder.

세계화로 여러 국가 간 상호작용이 활발해짐에 따라 세계시민의식 개념에 대한 관심도 높아졌다. 하지만, 세계시민의식 수준을 측정하고 검증할 수 있는 척도는 국내에 존재하지 않는 실정이다. 이에 본 연구는 Reysen과 Katzarska-Miller(2013)의 세계시민 모형(model of global citizenship) 척도를 국내 맥락을 고려하여 한국어로 번안 후 재타당화하였다. 이를 위해 번역과 역번역 과정을 통해 문항을 한국어로 변환하고 성별과 연령대를 층화하여 단순 무작위 추출로 표집된 전국 20세에서 69세 사이의 일반인 1,581명을 대상으로 척도의 내용타당도, 구성타당도 및 신뢰도를 검증하였다. 요인분석 결과, 세계시민의식의 속성은 4개 하위요인으로 구분되었고 이를 각각 ‘다양성 존중’, ‘규범적 환경’, ‘지속가능성’, ‘글로벌 인식’으로 재명명하였다. 이 결과를 바탕으로 세계시민의식 척도의 적용과 의의를 논의하였다.
Quantitative trait loci controlling the amino acid content in rice (Oryza sativa L.)
유수철 한국식물생명공학회 2017 JOURNAL OF PLANT BIOTECHNOLOGY Vol.44 No.4
The amino acid composition of rice is a major concern of rice breeders because amino acids are among the most important nutrient components in rice. In this study, a genetic map was constructed with a population of 134 recombinant inbred lines (RILs) from a cross between Dasanbyeo (Tongil-type indica) and TR22183 (temperate japonica), as a means to detect the main and epistatic effect quantitative trait loci (QTLs) for the amino acid content (AAC). Using a linkage map which covered a total of 1458 cM based on 239 molecular marker loci, a total of six main-effect QTLs (M-QTLs) was identified for the content of six amino acids that were mapped onto chromosome 3. For all the M-QTLs, the TR22183 allele increased the trait values. The QTL cluster (flanked by id3015453 and id3016090) on chromosome 3 was associated with the content of five amino acids. The phenotypic variation, explained by the individual QTLs located in this cluster, ranged from 10.2 to 12.4%. In addition, 26 epistatic QTLs (Ep-QTLs) were detected and the 25 loci involved in this interaction were distributed on all nine chromosomes. Both the M-QTLs and Ep-QTLs detected in this study will be useful in breeding programs which target the development of rice with improved amino acid composition.
Lamotrigine에 의해 유발된 항경련제 과민증후군
유수정(Su Jeong You),고지연(Ji Yeon Koh),강훈철(Hoon-Chul Kang) 대한소아신경학회 2007 대한소아신경학회지 Vol.15 No.1
저자들은 라모트리진으로 인한 발열, 피부발진, 호산구증 그리고 간침범을 동반한 항경련제 과민증후군을 경험하였고, 이를 스테로이드와 정맥 면역글로불린으로 치료하여 완치된 환아 1례를 경험하였기에 보고하는 바이다. Lamotrgine is an antiepileptic drug that is effective for multiple types of seizure and has side-effects such as headache, nausea, dizziness, diplopia, ataxia, cutaneous lesions, and anticonvulsant hypersensitivity syndrome. Anticonvulsant hypersensitivity syndrome consists of the hallmark features of fever, rash, lymphadenopathy and internal organ involvement, induced by aromatic anticonvulsants, for example phenytoin, phenobarbital, carbamazepine, and lamotrigine. We report a case of 13-year-old girl who had a fever, generalized erythematous skin eruption, facial edema, eosinophilia, and elevated liver enzyme induced by lamotrigine and resolved with discontinuation of medication and intravenous steroid and immunoglobulin.
