교통영향평가 합리화를 위한 교통량 예측기법 연구

안정근,이재춘 대한교통학회 1998 大韓交通學會誌 Vol.16 No.3

교통영향평가는 1985년 서울시에서 실시된 이후 사업 시행자에 의해 개발지 주변 도로 교통상황을 개선하는데 크게 기여하여 왔으며 향후 이러한 교통유발 원인자 부담원칙 에 의한 교통개선체제는 지방 자치화 시대를 맞이하여 계속 유지될 전망이다. 하지만 교통 영향 평가시 도로개선의 판단 기중이 되는 개발에 따른 교통발생 예측량이 평가자에 따라 상이한 결과가 나타나고 이에 따른 상이한 주변 도로 서비스수준(LOS)이 도출되어 합리적 교통처리 방안 제시에 문제가 되고 있다. 이러한 문제는 광역적 교통량 예측 프로그램 이 용, 상이한 통행 발생원단위 사용, 그리고 일률적 교통량 예측범위에 기인한다. 따라서 본 연구는 교통영향 평가시 국내와 미국의 교통량 예측 방법 비교·분석을 통해 합리적 교통량 예측방법을 제시하였다.

공간적·비공간적 도시구조 변화에 따른 창조산업 인구 연구

안정근,황정규,Ahn, Jung Geun,Hwang, Jeong Gyu 대한토목학회 2013 대한토목학회논문집 Vol.33 No.6

국내 많은 도시들은 경제 성장률 하락에 따른 고용창출 하락, 출산률 감소에 따른 인구감소, 노령인구 증가에 따른 도시활력 감소, 도심 공동화에 따른 도시기능 쇠퇴 등 20세기에 겪어보지 못한 새로운 도시양상에 직면하고 있다. 이에 따라 이들 도시들은 도시의 당면한 문제를 해결하고 도시 경쟁력을 향상 시킬 수 있는 다양한 방안 중 하나로 창조도시에 대한 관심이 높아지고 있다. 창조도시는 주민들이 다양한 문화생활과 여가활동이 가능하고 혁신적인 산업을 진흥할 수 있는 장소가 풍부한 도시로서 과학자, 기술자, 건축가, 디자이너, 작가, 예술가, 음악가 등의 창조산업 인구에 의해 선도된다. 따라서 본 연구는 국내 도시를 인구규모별로 구분하여 어떠한 도시구조가 창조산업 인구와 관계가 있는지를 제시하는데 목적이 있다. 연구결과 광역시에서는 문화행사 수가 창조산업 인구와 관계가 있으며 대도시에서도 문화행사 수와 문화공간 수가 창조산업 인구에 영향을 미치는 것으로 나타났다. 한편 중소도시에서는 문화행사 수와 환경오염 관리시설이 창조산업 인구 유인에 영향을 미치는 것으로 나타났다. 따라서 창조산업 인구 유입에 가장 큰 영향을 미치는 요소가 도시문화임에 따라 도시 경쟁력을 강화하기 위해서는 다양한 도시문화 환경을 조성하는 것이 시급하다. A number of cities have been constantly decreasing their residents by the low quality of life and environment. A creative industry is being noticed for not only securing the competitiveness of the city but also increasing the number of population. Thus, the urban structure for inducing creative industry population becomes to major issue to the most of local governments. This study aims to suggest the relationships between urban structure and creative industry population based on different urban sizes. To measure the population of creative industry, this study used the 'National Business Survey' by the National Statistical Office, which classified the statistical data of industrial places on a basis of city, district, and borough. Based on the results of expert questionnaire surveys, it conducted an analysis on the importance of urban structure and drew some critical factors that have an important effect on attracting the population of creative industry. The relationships between creative industry population and urban structure evaluated by multiple regression analysis. This study found out that the cultural factors like cultural space or culture events were drawn as very significant factors that have a positive effect on the population of creative industry population. It is judged that the creation of culture environment, which can enrich the creative industry, is needed to strengthen the competitiveness of the cities.

RNA 의 히드록실아민에 의한 화학적 변형

안정근,박인원 ( Jeong Keun Ahn,In Won Park ) 생화학분자생물학회 1981 BMB Reports Vol.14 No.3

Chemical modification of uridine residues in yeast RNA was carried out at two different concentrations of hydroxylamine, 10 M and 5 M, pH 10 and 37℃, varying the reaction time. The degree of modification depended on the concentration of hydroxylamine : the range was ca. 4∼5% per hour at 10 M hydroxylamine, and 2% per hour at 5 M hydroxylamine. Modification rates decreased with the reaction time, probably due to the limiting effect exerted by the secondary structure of RNA. The modification reaction was highly specific to uridine residues under the above reaction condition, so that the modification reaction on cytidine residues was almost negligible. It is found that less than 1% of uridine residues was modified at pH 10 and 10 M of hydrnxylamine within 20 min. This reaction condition can be utilized for RNA sequencing in-chemical methods.

The Use of Korean Honorifics for the Heritage Koreans in the US

안정근 대한영어영문학회 2010 영어영문학연구 Vol.36 No.3

The purpose of the study was to investigate the use of Korean honorifics for the heritage Koreans in the US. The study found out that the heritage Koreans in the US did not use Korean honorifics much in their writings and talk to the elderly as well. In particular, scarcely did they employ honorific affixes. They also had difficulty in using honorifics consistently in a sentence or utterance. Group and gender differences were also found. There was a significant difference in the use of Korean honorifics between lower grade students and high school students. Girls used honorifics more often than boys throughout all the categories of honorifics. Social distance played a role for their use of honorifics, too. They used more honorifics when they talked to the minister than to the teacher. It is evident that the heritage Koreans did not realize the social, linguistic, and pragmatic importance of the proper use of Korean honorifics until they became grown-ups. (Chonbuk University)

Inhibition of Hepatitis B Virus Replication by in vitro Synthesized RNA

안정근,양연주,Young Sin Hoe,Jeong Ki Kim,Sang Yong Kim 대한화학회 2005 Bulletin of the Korean Chemical Society Vol.26 No.9

Human hepatitis B virus (HBV) is a pathogen related to the development of liver diseases including chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). However, the efficient methods to suppress HBV replication have not been developed yet. Therefore, we have used RNA interference (RNAi) as a potential tool for the suppression of HBV replication. Here, we designed a 21 nt small intefering dsRNA (siRNA) against hepatitis B virus X (HBx) RNA with 3' overhanging ends derived from T7 promoter. It has been reported that HBV X protein plays an important role in HBV gene expression and viral replication. The suppression of HBx gene expression by the 21 nt siRNA was investigated by Northern blot analysis and chloramphenicol acetyl transferase (CAT) assay. The level of HBx mRNA was decreased by siRNA in a dose-dependent manner. We also found that the 21 nt siRNA inhibited the HBV replication in hepatocellular carcinoma cell.

Decrease in spectral entropy by low tidal volume ventilation-associated severe hypercapnia -a case report-

안정근,정성미,박상진 대한마취통증의학회 2017 Korean Journal of Anesthesiology Vol.70 No.2

Severe hypercapnia can be predicted by a decrease in cerebral electrical activity. The authors describe a sudden decrease in spectral entropy due to severe hypercapnia-induced respiratory acidosis in a patient with chronic pulmonary obstructive disease during lung resection. After two and a half hours of low tidal volume ventilation in the lateral position, the state entropy suddenly dropped from 45 to 7, without any changes in the effect-site concentration of propofol, end-tidal carbon dioxide (CO2) tension, oxygen saturation, or arterial pressure. However, arterial blood gas analysis showed severe respiratory acidosis (pH 7.01, PaCO2 115 mmHg and PaO2 246 mmHg with FIO2 of 0.5). Immediate hyperventilation improved the state entropy and acid-base balance. Electroencephalography-based spectral entropy can detect severe hypercapnia in chronic pulmonary obstructive disease patients with a large arterial to end-tidal CO2 difference due to prolonged hypoventilation during thoracic surgery.

Why do Koreans explain a lot when making an apology?

안정근 대한언어학회 2012 언어학 Vol.20 No.3

This study examined why Koreans used explanations a lot when making an apology. In order to find out the major reasons of such a peculiar speech act of Koreans in apology, 175 respondents participated in this study and each was given a questionnaire to fill out their preference of apology options and their reasons for selecting such options. Most of the respondents took apology options with explanations as their preference and the foremost reason they used explanations when making an apology was to make themselves understood to the others in order to avoid misunderstanding. Women were more likely to make themselves understood to the others than men, whereas men thought that giving an explanation when apologizing was more polite and the right thing to do than women. The youngest group of people were most sensitive to have themselves understood to the others when making an apology.
