Standards boost technological innovation by promoting information sharing, compatibility, stability and quality. Identifying groups of companies that particularly benefit from these functions of standards in their technological innovation and commercialization helps to customize planning and implementation of standards-related policies for demand groups. For this purpose, this study engages in profiling of SMEs whose R&D objective is to respond to standards as well as those who need to implement standards system for technological commercialization. Then it suggests a prediction model that can distinguish such companies from others. To this end, decision tree analysis is conducted for profiling of characteristics of subject SMEs through data mining. Subject SMEs include (1) those that engage in R&D to respond to standards (Group1) or (2) those in need of product standard or technological certification policies for commercialization purposes (Group 2). Then the study proposes a prediction model that can distinguish Groups 1 and 2 from others based on several variables by adopting discriminant analysis. The practicality of discriminant formula is statistically verified. The study suggests that Group 1 companies are distinguished in variables such as time spent on R&D planning, KoreanStandardIndustryClassification (KSIC) category, number of employees and novelty of technologies. Profiling result of Group 2 companies suggests that they are differentiated in variables such as KSIC category, major clients of the companies, time spent on R&D and ability to test and verify their technologies. The prediction model proposed herein is designed based on the outcomes of profiling and discriminant analysis. Its purpose is to serve in the planning or implementation processes of standards-related policies through providing objective information on companies in need of relevant support and thereby to enhance overall success rate of standards-related projects.

In this study, using structural equation modeling, a policy acceptance evaluation model was developed to evaluate the service items of roadsthat affect the acceptance of the Safety Speed 5030 policy. The relationship of influence on policy acceptance was found to be as follows: In the driver group, satisfaction with mobility (0.411), economy (0.217), safety (0.181), and environment (0.089) are in the order of top priority; and in the non-driver group, satisfaction with safety (0.466), mobility (0.223), environment (0.194), and economy (0.111) are in the order of top priority. From these results, in order to increase acceptance of the Safety Speed 5030 policy, it is necessary to differentiate the provision of services according to the characteristics of each road user type. This infers it is important to improve mobility for roads with a high hierarchy mainly used by driver groups, and to improve safety for roads with low hierarchy mainly used by non-driver groups. Therefore, the evaluation model for acceptance of the Safety Speed 5030 policy suggested in this study can be used as basic data for activating the Safety Speed 5030 policy in the future by reflecting the qualitative evaluation of users.

This study intends to design a model that can effectively service policy data necessary for the implementation of new national agenda in order to provide high-quality policy information services that go beyond those of the existing Policy Information Portal (POINT) of National Sejong Library. To this end, it was determined that providing an integrated search environment, in lieu of data search through individual access, was necessary. Subsequently, four possible models for a national agenda service model were presented. First, designing a computerized system for both interface and electronic information source aspects was proposed for the national agenda service system operation. Second, designing the Linked Open Data system and the time-series service system for national policy information, providing the translation service of overseas original data, and securing the researcher's desired data were presented for the national agenda service information source operation. Third, strengthening public relations for policy users, building and promoting the site brand, operating SNS channels, and reinforcing the activation of auxiliary materials and the accessibility of external services were proposed for public relations of national agenda service. Fourth, expanding the information network with Open API, cloud service, and overseas libraries was proposed for collaborating and cooperating with the agenda service.

The purpose of this paper is to show the clustering trend and the empirical comparison and to choose the clustering ports for 3 Korean ports(Busan, Incheon and Gwangyang Ports) by using the Fuzzy(Average Index Transformation) DEA and Cross-efficiency models for 38 Asian ports during 11 years(2001-2011) with 4 input variables(birth length, depth, total area, and number of crane) and 1 output variable(container TEU). The main empirical results of this paper are as follows. First, clustering results by using Fuzzy(AIT)DEA show that 3 Korean ports[Busan(56.29%), Incheon(57.96%), and Gwangyang(66.80%) each]can increase the efficiency. Second, according to Cross-efficiency model, Busan(Hongkong, Kobe, Manila, Singapore, and Kaosiung etc.), Incheon(Aquaba, Dammam, Karachi, Mohammad Byin Oasim and Davao), and Gwangyang(Damman, Yokohama, Nogoya, Keelong, Kaosiung, and Bangkok) should be clustered with those ports in parentheses. Third, when both Fuzzy(AIT)DEA and Cross-efficiency models are mixed, the empirical result shows that 3 Korean ports[Busan(71.38%), Incheon(103.89%), and Gwangyang(168.55%) each]can increase the efficiency. The efficiency ranking comparison among the three models by using Wilcoxon Signed-rank Test was matched with the average level of 66%-67%. The policy implication of this paper is that Korean port policy planner should introduce the Fuzzy(AIT)DEA, and Cross-efficiency models with the mixed two models when clustering is needed among the Asian ports for enhancing the efficiency of inputs and outputs. Also, the results of SWOT analysis among the clustering ports should be considered.

1959년(年) 11월(月) St. Louis 연방은행 Review지(誌)에 발표된 통칭 St. Louis 방정식으로 불리는 Miehael W. Keran의 모형은 학계에 지대한 반향을 이르켰다. 동모형은 1919년에서 1969의 50년간의 자료를 토대로 재정정책 및 화폐정책을 대표하는 두 설명변수와 경제활동의 전반적지표로서 국민소득을 종속변수로하여 전자의 후자에 미치는 영향을 계량적으로 파악코저하는 회귀분석인데 만일 방정식이라는 접근방식이 구조적 특징이다. 본 연구는 1965년에서 1980년까지의 새로운 자료에 입각하여 동모형의 이론적 타당성을 비판적으로 검토하고, 또한 통계학적 신빙성을 제고(提高)할 수 있는 개선방안(改善方案)을 모색코저 시도(試圖)한 것이다. 우선 단일방정식(單一方程式) 접근(接近)의 문제점(問題點)인 종속변수의 EXOGENEITY를 시험하기 위(爲)한 소위 Reverse-Causation Argument를 재점검(再點檢)하였고, 이이서 동모형의 Specification을 면밀히 살펴왔다. 특히 이자율의 변동을 설명변수로 도입해서 동변수가 경제활동전반에 끼치는 영향을 추정함으로서 설명변수의 추가적 설정(說定)의 타당성여부를 검토하였다. Keran의 결과가 t, D-W 및 $R^2$ 등의 주요 통제치가 매우 미흡한 수준이였으므로 이들 통계치의 제고(提高)를 위해 Almond-lag 방식을 Cuchrane/Oreutt 기법(技法)과 결합해서 적용하여 Almond의 지연구조에 녹유(綠由)하는 자동상관(自動相關) 효과(效果)를 배제(排除)코저 하였다. 끝으로 본연구대상기간인 '65년에서 '80년간의 역사적 발전을 배경으로 동모형의 적용 결과를 재조명(再照明)함으로서 동모형의 타당성을 살펴봤다.

그동안 사회적 여러 갈등의 갈등 조정을 위한 연구나 기술들은 주로 갈등발생원인들 중 법/제도적이나 정책추진 방법론 등 한 두 가지측면을 고려하여 평면적 분석을 시도하는 것이 대부분이고 특정지역 및 사례에 제한적으로 적용되는 것이 일반적이었다. 이와 같은 갈등 조정의 한계를 극복하기 위해 최근에는 이해당사자의 참여를 유도하고 공학적으로 접근하여 여러 대안 및 시나리오에 대해 모색할 수 있는 공영시각모형이 소개되면서 많은 정책결정과 수자원관리, 수질관리 분야 등에 널리 활용되고 있다. 하지만 객체지향을 내세우고 있는 공영시각모형은 신속한 모의 및 쉽게 모형을 다룰 수가 있다는 장점이 있으나, 공간적인 분석 및 표현은 불가능하다는 단점을 가지고 있다. 이에 본 연구에서는 ArcGIS를 기반으로 HEC-RAS와 연계하여 대상지역의 선 면적 개념의 치수적인 문제점을 도출시켜 이해당사자들에게 인식 및 이해시킬 수 있도록 하였으며, 댐 규모나 다른 대안이 수립되는 경우 이에 따른 수위저감효과와 홍수범람모의 및 홍수피해액 등을 제시할 수 있도록 개발하였다. 모형의 정확성, 신속성 및 다른 지역에서의 적용성 등을 확인하기 위하여 한탄강댐 갈등사례가 있었던 임진강 유역에 적용하여 모의운영 하였다. 그 결과 가상의 여러 대안에 의한 각 결과를 잘 제시하고 있었으며, 댐 건설 갈등현안 중 치수부문에 적용되어 갈등 조정에 기여할 수 있을 것이라고 판단된다.

Drawing on a case of the construction of high-tech medical complexes, this study demonstrates the process of policy formuation. Beause the construction of high-tech medical complexes involves various analytic elements, and changes of political, economic and social environment, Kingdon's Policy Stream Framework is employed for analysis. The analysis ranges from the embarkment of the Presidential Committee on Healthcare Industry Innovation (PCHII) in August, 2005, to the enactment of High-tech Medical Complex Special Act in March, 2008. The analysis illuminates that policy formulation from agenda setting to enactment in the area of biomedical industry involves multiple factors and policy streams. An enactment of policy agenda particularly depends on the roles of multiple stakeholders as welll as policy leaders.

This paper presents a formal model of social policy development. The model shows that the development of social policy depends both on the social policy preferences of voters and on the political institution which mediates the preferences of voters. In the direct democracy, median voter's social policy preference is critical because he is Condorcet winner in a pairwise vote. But in the representative democracy, political parties design social policy to win the support of a majority of voters. Hence, the political institution like electoral rule may affect social policy outcome. The model presented in this paper contrasts 3 alternative constitutional features and investigates how they affect social policy outcome. In result, this papers emphasizes that policy preferences of voters and political institution may be key variables to explain social policy development and divergence among welfare regimes.

A transit assignment model can forecast the behaviors of transit users. thereby playing an important role In the evaluation of transit policies. Most existing transit assignment models are based on the models for passenger cars; therefore they cannot reflect the specific characteristics of transit modes. In addition most of the existing models are based on a single transit mode (bus or rail), and they cannot forecast the behaviors of transit users in a changing mass transportation system. The goal of this study is to overcome these problems with the exiting models and to develop a more realistic model. The newly developed model is based on mixed transit modes and is a stochastic model that can reflect the different preferences of each transit user for travel time and transfering. Data gathered from the Seoul metropolitan area's smart card are used to calibrate this model. This study is expected to be used for the evaluation of transportation policies and to attribute the development of transit revitalization strategies.
