This study analyzed the institutional characteristics of large scale national R&D policies in Korea. The analysis examined the continuity and change of the policy institution. It dealt with G7 Project, 21C Frontier Project, and Next Generation Growth Engine Project as the major large scale national R&D policies in Korea. The theoretical approach of this study is to the continuity and change or evolution of policy institution from the perspective of new institutionalism. Based on the theoretical analysis, it emphasized the analysis of the institutions in three different levels: macro, meso, and micro level. In the analysis, the research examined the idea of policy institution or policy goal, participants in the policy institution, and policy instruments in different levels. The outcome of the analysis shows that the policy of large scale national R&D in Korea has the institutional continuity in the macro level. In the meso level, however, the policy institution changes due to the administration change and the influence of political economic environment. In the micro level, the policy institution changes based on the symbolic influence of policy goal and the interest of bureaucrats. The research finds that the micro and meso level institutional changes cause the evolution of policy institutions and the major change of policy institution.

이 연구에서는 1970년부터 2002년까지의 시계열 자료를 이용하여 우리나라의 사회경제상황이 이혼율 증가에 어떤 영향을 미쳤는지를 분석하였다. Land and Felson(1976)의 거시 동태 사회지표 모형을 바탕으로 경제상황과 남녀 성비, 그리고 이혼 관련법의 개정 등을 분석모형에 포함시켰다. 경제상황에는 여성의 경제활동 참여율, 실업률 그리고 1인당 국내총생산으로 측정된 소득수준을 포함시켰다. 분석의 결과는 실업률과 소득수준이 이혼율의 증가 추이에 영향을 미치는 것으로 나타나고 있다. 1인당 국내총생산의 수준이 높을수록 이혼율도 증가하는 분석의 결과는 경제적 호황기에는 이혼율이 증가하고 경제적 쇠퇴기에는 이혼율이 감소한다는 선행연구의 주장을 실증적으로 뒷받침해주고 있다. 그러나 실업률이 증가할수록 이혼율도 높아지는 것으로 분석되고 있는데 이는 혼인의 결정 요인과 관련한 남성 중심의 가설을 뒷받침하고 있다. 이러한 연구의 결과는 경제상황을 구성하는 하위요인(소득수준과 실업률)이 이혼율의 변화에 미치는 영향의 기제가 다름을 보여주고 있다. 사회경제상황 자체보다는 경제상황의 변화가 이혼율의 변화에 어떤 영향을 미치는지를 분석하기 위하여 회귀분석의 모형에 변화율을 변수로 포함시킬 경우에는 1977년의 가족법 개정만이 이혼율의 변화율에 영향을 미치는 것으로 나타났다. 분석에서 이혼율에 영향을 미치는 모든 거시적 요인을 통제하지 못하고 있는데, 이는 이 연구의 내적 타당도를 저해하는 요인이 된다. 우리나라의 경우 이혼율은 경제적 상황보다는 오히려 문화적 또는 사회적 요인에 의해서 결정될 수도 있기 때문에 이혼율을 결정짓는 경제적, 문화적, 그리고 사회적 요인들을 모두 포함하는 분석 모형의 개발과 실증 자료를 이용한 검증은 향후의 연구 과제로 남는다.

고속도로-연결로는 두 개의 교통흐름이 서로 상충되는 지점으로서 복잡한 교통행태를 나타내고 고속도로 구간 중 용량저하 및 교통와해현상, 난류현상이 일어나는 구간으로서 운영상 문제점이 많이 일어나고 있는 상태이다. 이 구간에서의 운영상태가 전체 시설물의 운영상태에 큰 영향을 끼친다는 점을 감안할 때, 이 구간의 국내자료를 토대로 한 교통류 분석은 중요한 의미를 가진다. 따라서, 교통행태에 대한 미시적인 분석이 이루어지지 않은 상태로 기존의 HCM 모형과 같은 거시적인 분석 방법만을 가지고는 분류구간 교통현상을 규명하기 어렵다. 본 연구에서는 기존 연구들 분석방법의 문제점을 해결하기 위해, 고속도로-연결로 구간중 유출부 구간을 대상으로 현장조사를 실시하였고, 지점(구간)과 차로로 세분하여 미시적인 방법으로 교통특성을 규명하였다. 또 한 유출부 구간의 여러 지점에서 지점 및 차로별 교통량을 예측할 수 있는 교통분포 모형식을 개발하였다. 정립된 교통분포 모형식을 적용해 본 결과 유출부 구간의 분석 및 서비스 수준의 평가는 연결로 접속차로(Vl)의 교통량만을 고려하여 분석하는 것은 합리적이지 않고, 연결로나 본선 모두와 진입부를 포함한 연결로 전체를 다 고려해야 한다는 것을 알 수 있었다. 미시적인 분석방법을 통한 차로별 교통분포 모형식은 기존 분석방법과 비교하여 더 정확하게 그리고 폭 넓은 분석 및 적용하기에 손쉬운 모형이라는 점에서 상당히 효과적인 분석방법이라고 할 수 있다. 하지만 본 연구의 결과는 한 조사지점에 대한 적은 자료를 토대로 하였기 때문에 실제적용 가능성에서 향후 보강할 필요가 있으며, 다른 지점의 현장조사와 세밀한 비교연구가 필요하다.

Surveying urban tributary vegetation is based mainly on field sampling at present. The tributary vegetation survey integrating UAV NIR(Unmanned Aerial Vehicle Near Infrared Radiance) imagery and in-situ point photo has received only limited attentions from the field ecologist. The reason for this could be the largely undemonstrated applicability of UAV NIR imagery by the field ecologist as a monitoring tool for urban tributary vegetation. The principal advantage of UAV NIR imagery as a remote sensor is to provide, in a cost-effective manner, information required for a very narrow swath target such as urban tributary (10m width or so), utilizing very low altitude flight, real-time geo-referencing and stereo imaging. An exhaustive and realistic comparison of the two techniques was conducted, based on operational customer requirement of urban tributary vegetation survey: synoptic information, ground detail and quantitative data collection. UAV NIR imagery made it possible to identify area-wide patterns of the major plant communities subject to many different influences (e.g. artificial land use pattern), which cannot be acquired by traditional field sampling. Although field survey has already gained worldwide recognition by plant ecologists as a typical method of urban tributary vegetation monitoring, this approach did not provide a level of information that is either scientifically reliable or economically feasible in terms of urban tributary vegetation (e.g. remedial field works). It is anticipated that this research output could be used as a valuable reference for area-wide information obtained by UAV NIR imagery in urban tributary vegetation survey.

The purpose of this paper is to present a conceptual framework and a stage of development of trust building and to study the factors affecting on the trust building in economics space. Conceptual framework on trust building in economics space is combined of in the three approaches. The macro(structural and institutional) approach includes normative and regulative factors(laws, norms), and positionality in social and economic systems(beliefs, political ideologies, institutions). The meso(intersubjective) approach contains the personal fronts(expressive factors, social cues, significant symbols) and settings(physical space, intermediary such as technologies & knowledges). The micro(subjective) approach comprises the willingness(internalization of value) and calculation(risk and uncertainties analysis) of economic actors. According to sustainable cooperation among economic actors, trust building to the macro(structural and institutional) level, the meso(intersubjective) level, and the micro(subjective) level develop by stages. The factors such as long-term and repeated interaction, information sharing and reciprocity, interdependence and asset specificity, uncertainty, proximity, and culture & norm of corporate and formal institution are determinants on the trust building across economic actors in economic space.

The works of a literary and cultural historian Franco Moretti are conspicuous in many ways. Trained in Marxism and Russian formalism, he participated in the construction of the New Left in England. Also, he interestingly interpreted the socialization of the individual through the genre of bildungsroman. Then, he shifted his research interest to the notion of world literature, and to explore its global scale, he developed his own quantitative approach combined with advanced computer technology in digital humanities. His recent publication reveals that Moretti conducted a social critique of the European bourgeois culture with his new quantitative method. His macroscopic view of literature and use of cutting-edge technology in his research inspire historians of Korean literature located in the so-called periphery of world literature. Therefore, the purpose of this study is to examine the idea of world literature outlined by Franco Moretti by reviewing his method called "distant reading" and examples of such an approach. His distant reading is to construct a macroscopic archive through inclusion of forgotten works from literary history and to analyze morphological patterns that frequently appear in the archive. His book entitled Graphs, Maps, Trees is a collection of examples of which he applied distant reading. By delving into such cases, I will raise questions about Moretti's macroscopic perspective of world literature in conjunction with Korean literature. As located at the periphery of global circulation of literary knowledge, Korea appropriated Western genres, established its literary institutions, and developed book markets through modern newspapers and magazines. This experience of furthering modern literature through periodicals would provide another view to revisit Moretti's world literature.

The main purposes of this study are to describe regional differentials of the rate and to explore factors impacting on the regional differentials among the elderly's suicide rate in the Republic of Korea. Suicide data among 16 provinces from 2000 to 2008 were used for the statistical analyses. Six independent variables, such as crude divorce rate, GRDP per capita, welfare budget proportion, number of leisure facilities, number of medical and housing welfare facilities, and number of sports facilities are introduced for the multiple regression analyses. Elderly suicide rate, female elderly's suicide rate, and male elderly's suicide rate are used for the dependent variables. The findings of this study are as follows: Elderly's suicide rate has been increased constantly since 2000 and regional differentials of the elderly's suicide have been existed over time. According to the multiple regressions analyses, number of sports facilities(${\beta}$=-521), welfare budget proportion, and number of leisure facilities(${\beta}$=-219) have shown statistically significant negative relationships with the elderly's suicide rate. On the other hand, number of medical facilities(${\beta}$=0.550), crude divorce rate(${\beta}$=0336) have shown statistically significant positive relationships with the elderly's suicide rate in the Republic of Korea. Finally, some policy implications for alleviating the elderly's suicide rate are introduced and discussed.

The existing selected station analysis (SSA) method analyzes the link transfer mode data between origin and destination of individuals passing through stations from a microscopic standpoint. As such, existing SSA is insufficient as it uses integrated analysis using macroscopic data such as subway lines. This research builds a line chain OD based on path search of individual passenger's movement through the subway, and explores means to utilize the findings. First, a method is proposed that searches the traversed subway path from the linked passage modes that the passenger uses and applies the results to SSA line analysis. Compared to the existing SSA, this method provides for analysis of commonly conflicting features such as the line on which the station is passed, and the stations included on the line thanks to the presence of complete information of the individual passenger's traversed path. It also allows for integrated observation of the line chain OD that approaches a certain station. For enhanced understanding, Seoul Metro Line 9 is used as a case study to demonstrate the integrated formulation concept of line chain OD centered around a certain station as well as the macroscopic features of the traversed path that approaches stations included on the line.

This research addresses the effect of heavy vehicles (especially trucks) in terms of passenger car Equivalents from a capacity viewpoint. A formulation that estimate PCE in this paper is derived by introducing appropriate headway measurements into Huber's general equation for PCEs. In this equation, PCE value is expressed in terms of headways for four different kinds of pairs; pairs of leading and following vehicles ; P-P, P-T, P-T, T-T. The mean value of headway for each case is estimated through the regression analysis. Finally, the approach used in this research was compared with macroscopic approach which analyzed a speed-density relationship to evaluate PCE.
