In this paper, we conducted a comparative study on the methodology for impact analysis as the economic grounds for formulating policy and investment plan concerned with utilizing spectrum resource. In order to provide numerical results for objective comparison and selection among policy and investment planning, methods to be analyzed are focused on quantitative methodology based on mathematical models, consequently the utility and limits of econometric model, input-output analysis, computable general equilibrium and system dynamics are compared from various viewpoints including analysis cost. Besides, we compared the methodologies in the standpoint of utilizing spectrum and discussed the recent findings of mixed models combining multiple methodologies to exploit the advantages of each methodology and to offset the limit. Results of the research can be used as reference indicators to select the method that conforms to the purpose and priority of analysis verifying the efficiency of execution of policies and investment plans.

This study surveyed the physical properties of the domestic and foreign worsted fabrics which are used for men's garments. For this purpose, forty specimens which were divided into 1st fourteen specimens and 2nd twenty six ones were prepared and the physical property assessment by Blind field test was carried out by test committee. The subjective test items by Blind field test were chosen as handle(softness, flexibility), color(brightness, deepness), appearance(cleanness, natural lustre) and comparison priority.

The purpose of this study is to suggest improvement plan for a commentary on figure skating in Korea from comparing to NBCSN and MBC's coverage of the 2018 Pyungchang Olympic Games employing both of quantitative and text analysis. Results indicate that NBCSN and MBC's commentary on figure skating have definitely different characteristics in terms of expertise and dramatizing ability. The commentator of MBC frequently used monotonous and repetitive emotional expression and provided incoherent information in very automatic way. Whereas, NBCSN's comments expressed very diverse way on introduction of players, explanation of technique and evaluation, especially on dramatizing ability to contextualize combining players' performance and background information.

In relation to slope stability analysis, geologic characteristics and engineering properties of the discontinuities in three slopes selected are compared and analyzed by both square-inventory method and scanline survey. The aim of the study is in evaluating which method is applied better in slope stability analysis by comparing results of the two methods with those of direct observation on outcrop of slope failures generated. In each slope, results of comparative analysis among geologic and engineering properties are analyzed similarly one another. However, results of orientation analysis in slope 2 are different each other, which indicates orientation of joints in slope 2 depends on persistency and frequency of each joint and also indicates appearance of new joint set with different orientation. Probability density distribution and spacing in slope 3 are high in comparison to those in slope 2 and 3. The reasons are that distribution of psammitic rocks and development of minor folds in slope 3 unlike slope 2 and 3 are closely associated with development of joints. The research data indicate that the square-inventory method predicts more precise failure aspects and is more effective way than scanline survey in analyzing slope stability of the study area.

National research and development(R&D) project plays an important role in the economic growth of a country as well as a company. This article aim to examine the development of the performance evaluation framework for assessing the contribution of national research and development(R&D) program to productivity growth. The main idea of this paper begins with the employment of between-group analysis for evaluating the returns to R&D. The method of this study is based on the comparison of productivity growth between different groups with time series data, not cross-sectional approach with one period. In these regards, backward effect and forward effect are operationally defined as a measurement for contributions of R&D in this study. The results of analysis gives that the outcomes of between-group analysis shows the lower performance of R&D compared to the within-group analysis. while the difference was not especially evident with the case of operating profit variable, but sales variable.

It is important for regional comparative analysis about economically active population ratio by sex and total economically active population ratio to a policy data of central and local government. Through the result of comparative analysis, Central and local government can use policies distinctively according to the region and keep the efficiency of detail policy application. This paper shows regional comparative analysis about economically active population ratio by sex for the Seoul metropolitan region, Gangwon region, Chungcheong region, Youngnam region, Honam region using the economically active population survey data in 16 cities and provinces. We used the survey of economically active population for 13 years from 2000 to 2012, we calculated total economically active population ratio and economically active population ratio by sex about the 5 regions. And we analyzed the relative ratio between economically active population ratio of male and female by each region, we also analyzed the results of regional comparative analysis by sex.

통신과 방송의 융합화 현상에 따라 선진국에서는 CATV 망을 통신망과 경쟁하는 대체 인프라로 활용하고자 하고 있다. 반면에 일부 선진국에서는 여전히 CATV와 통신망간의 경쟁을 엄격히 금지하고 있다. 본 고에서는 이러한 국가별 정책차이를 유럽, 미국, 일본 등 17개국을 대상으로 비교분석하고 각국의 정책 특징을 유형화하여 정리하고자 하였다. 아울러 선진국과의 비교분석 관점에서 우리나라의 CATA망 정책을 살펴보고 검토되어야 할 과제를 도출하였다.
