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.

RNA의 히드록실아민에 의한 화학적 변형

안정근,박인원,Ahn, Jeong-Keun,Park, In-won 생화학분자생물학회 1981 한국생화학회지 Vol.14 No.3

효모 RNA를 10 M 히드록실아민, pH 10, $37^{\circ}C$와 5 M 히드록실아민, pH 10, $37^{\circ}C$에서 반응시켜 우리딘을 변형시켰다. 우리딘의 변형 정도는 히드록실아민의 농도에 비례한다. 즉 10 M 히드록실아민의 경우 시간 당 4~5%, 5 M 히드록실아민의 경우 시간 당 약 2% 정도였다. 우리딘의 변형 반응 속도는 시간이 경과함에 따라 감소하는데 그 원인은 RNA의 이차구조가 히드록실아민의 반응을 크게 억제하기 때문이라고 본다. 히드록실아민의 이러한 조건에서의 반응은 우리딘에 매우 선택적이고 시티딘의 변형은 무시할 수 있었다. 위의 실험 결과에서 히드록실아민으로 RNA의 우리딘을 변형시킴으로서, RNA의 우리딘 염기 배열 순서를 결정하는데 이용하기 위한 반응 조건은 10 M 히드록살아민, pH 10, $37^{\circ}C$로 20분 보다 짧아야 함을 알았다. 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 $37^{\circ}C$, 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.

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 purpose of this study is to review the various valuation techniques of intangible assets. The value of intangible asset by the income approach can be measured as the present value of the economic benefit over the intangible asset's remaining useful life. The typical methods used in intangible asset economic income projections include extrapolation method, life cycle analyses, sensitivity analyses, simulation analyses, judgment method, and tabula rasa method. There are several methods available for estimating capitalization rates and discount rates for intangible asset, in which we have discussed market extraction method, capital asset pricing model, built-up method, discounted cash flow model, and weighted average cost of capital method. As the capitalization methods for intangible asset, relief-from-royalty method, excess earnings capitalization method, profit split method, residual from business enterprise method, postulated loss of income method and so on have been reviewed.

Cross-cultural variations of apology realization in Korean

안정근(Jeong Khn Ahn) 한국사회언어학회 2011 사회언어학 Vol.19 No.2

This study investigates apology strategies for Koreans in six offence contexts in an attempt to find out how these contexts are perceived and what apology strategies are used by them and to compare the findings of the study with other studies cross-culturally. The data of apologies in Korean were collected in a questionnaire in which 175 native speakers of Korean who were participated in the study evaluated socio-pragmatic factors and completed dialogs which were related with each offence situation. As general apology strategies, IFIDs (Illocutionary Force Indicating Devices) and responsibility were used mostly, which supports the similar findings in the CCSARP (Cross-Cultural Speech Act Realization Project). As a situation specific apology strategy, however, explanation was used in a surprising degree, which was not shown in the findings in the CCSARP. In addition, modifications of apology strategies such as intensifiers, minimizers, and concern for the hearer in the study were also used much more than other studies in the CCSARP. Correlations between severity and obligation in the study support other studies, however correlations between IFIDs and obligation, inverse correlations between responsibility and explanation in the study are quite unique in apology studies.

The three traditional approaches can be utilized when appraising machinery and equipment. The cost approach and market approach are applied in the valuation of individual items of machinery and equipment. The income approach is conceptually applied in the valuation of group properties including machinery and equipment and other business assets. The machinery and equipment which has any utility value as is can be appraised under the premise of value in exchange as a piecemeal of orderly disposition. The market approach establishes the fair market value of basic units by analysis of recent sales or asking prices of comparable property. In establishing value of individual items of machinery and equipment by the market approach, three techniques can be used: direct match technique, comparable match technique and percent of cost technique. Through a series of calculations, the income approach determines the amount of supportable for the group of machinery and equipment. This amount of supportable is compared to the fair market value-in-place indicated by other approaches. When using the cost approach, the appraiser first determines the proper level of current cost and then measures the value of subject items by deducting the amount of three elements of depreciations from the current cost of subject assets.
