This paper aims to identify the spatial concentrations and linkage properties of industrial clusters in the Chungbuk Province region in Korea using a three-step approach, which is composed of the cluster index, Getis-Ord's $Gi^*$, and qualitative input-output analysis. The results of the study reveal: a) what industrial sectors are concentrated and where they are; b) where the spatially interdependent industries are; and c) how the industrial sectors of the identified clusters in different locations are vertically interconnected. In addition, the degree of strength of the interindustry linkages between industrial clusters are assessed. Based on the findings, some plausible industrial policies are suggested.

국가 단위에서의 원조효과 평가는 대부분 정성평가에 머물고 있지만, 원조 프로젝트의 동질성이 강하면 정량평가를 시도할 수 있다. 본 논문은 정량평가에 사용할 수 있는 다양한 방법론의 장단점을 비교하였다: 성장이론에 기반한 패널분석, 산업연관분석, 사회계정행렬분석, CGE모형, DSGE모형, 시계열분석. 그리고 산업연관분석을 이용하여 사업의 동질성이 높은 한국 유상원조의 대베트남 지원의 효과를 추정하였다. 합리적 추정을 위해 적절한 투입산출표의 선택, 현재가치화를 통한 시점 일치, 최종수요 발생의 산업별 구성, 구속성 원조 특성 등의 문제를 고려하였다. 분석결과 1995?2016년에 승인된 EDCF의 대베트남 지원은 베트남에서 약 59억 달러의 생산과 약 17억 달러의 부가가치를 창출한 것으로 추정되었다. 그리고 지원에 따른 베트남 1인당 소득 증가는 베트남의 빈곤율을 0.21%p 낮추는 데 기여한 것으로 추정되었다.

Korea's R&D investment has significantly increased in recent years and the quantitative outputs such as number of papers and patents have also increased with the investment. However, the quality of R&D outputs has not been fully addressed. In particular, quality of technical performance, such as the quality of patents, has attracted little attention. In this paper, a Data Envelopment Analysis (DEA) method was used to construct models for efficiency analysis of R&D investment, focused on quality of technical performance. Indices were proposed to analyze the quantitative and qualitative efficiencies of R&D investment. In order to effectively analyze R&D efficiencies, the measurement units of the input and output variables were standardized. Based on cases of livestock quarantine R&D projects of Korea, the quantitative and qualitative efficiencies of national R&D projects were analyzed and factors that would influence R&D efficiencies were identified. This paper suggests that both quantitative and qualitative efficiencies should be considered when measuring R&D efficiency. Also, it is recommended to carefully consider the characteristics of R&D projects during project selection stage.

대학 학부생들의 SW융합 역량을 향상하기 위해서는, 관련 강좌의 개발과 함께 학부생들의 코드 설계 역량을 평가하는 방법이 연구되어야 한다. 기존 연구에서는 코드 결과물에 대해 정성적인 평가방법과 정량적인 상대평가방법이 있었으며, 정량적인 상대평가방법에서는 문제분해깊이 수, 함수재사용 회수와 함수 개수를 측정하여 평가하였다. 본 연구에서는 기존 연구에서 제시되지 않은 평가방법으로서, 코드 설계 시 입력과 출력 정보종류의 수를 제시하는 문제를 이용한 평가방법을 제안하였다. 본 논문에서 제안한 평가 문제들은 입력 정보 종류의 수와 출력 정보 종류의 수를 3개까지 적용하였다. 이를 통해 5가지 코드설계 평가문제를 제시하고 코드설계 점수를 정량적으로 산출하는 방법을 제안하였다. 제안한 평가방법을 적용한 강좌를 통해 100명 학생 응답자들의 코드들을 수집하고 분석하였다. 결과 분석을 통해, 문제분해깊이 수는 입력 정보의 종류 개수에 비례하고, 함수 재사용 회수는 출력 정보의 종류 개수에 비례하며, 함수 개수는 입력과 출력 정보의 종류 총개수에 비례하는 상관성을 나타내었다. 마지막으로 100명 응답자의 평가 점수 분포를 분석하여, 5가지 입출력 정보 조건 평가문제에 따른 코드설계 평가 방법이 유효함을 설명하였다.

본 연구에서는 산업연관분석모형을 이용한 속초시 23개 스포츠이벤트가 지역경제에 미치는 파급효과를 추정하는데 있다. 스포츠이벤트의 승수는 생산물, 부가가치, 개인소득, 간접세, 고용에 대한 거래로부터 도출 되었다. 이 조사는 이벤트에 참여한 선수, 임원, 관중 등 표본으로 하여 총지출을 추정하였다. 분석결과 스포츠이벤트가 지역경제에 미치는 파급효과에서 생활 스포츠가 엘리트 스포츠보다 질적인 전망에서 효율적인 것으로 나타났고, 반면 양적인 전망에서는 엘리트 스포츠가 생활스포츠보다 효율적인 것으로 나타났다. 따라서 본 연구결과가 속초시지역에 대한 스포츠이벤트 개최가 지역경제활성화에 어느 정도 기여하고 있는가를 가늠해 볼 수 있는 척도로서 제시했다.

The objective of this study was to evaluate total current under steady-state conditions for a material undergoing corrosion using the electrochemical frequency modulation (EFM) technique, taking into account the presence of solution resistance and double layer capacitance. The analysis involving linearization of the Tafel curve allowed for the estimation of corrosion parameters. Results showed that the output signal was dependent on fundamental frequencies and their multiples. In addition, the output signal almost manifested itself at frequencies that were sums of fundamental frequencies of the applied sinusoidal signal. The harmonics calculated showed a significant shift from the principal frequency of input signals. The investigation involved the influence of corrosion current and anode-to-cathode Tafel slope ratio on faradaic and non-faradaic currents (including the average and RMS). The model presented showed both qualitative and quantitative improvements over the previously developed EFM technique that ignored the influence of solution resistance and the double layer capacitance while assuming the applied DC potential corresponded to the corrosion potential of the corroding material.

Many different kinds of wargame models have been developed and used in training and analysis purpose. However, there has been few wargame model which analyze corps or division level operational analysis. Recently KIDA develops corps level operational analysis model based on START(simplified tool for analysis of regional treats) model developed by RAND. This model runs in a PC level with 2MB memory and provides one day combat results within 30 seconds. Only one or three person can operate this model and evaluate multiple corps level operational analysis including chemical effects, $C^3I$ capacity, new weapon system effectiveness and other qualitative effects. We tested this model and evaluated input and output data. We showed that this model can be applied in division level operational analysis also. As an example division level application procedure and sensitivity analysis data was provided. We also find some limitation and problems in the model and suggest application areas and improving methods.

Purpose - In this study, we try to measure the efficiency of the traditional market and university cooperation projects and present the direction of policy improvement for the near future by converging the system, which exerts to secure the competitiveness and revitalize its centered-city, and the recent policies that have new business and social Research Design, Data, and Methodology - In order to improve this situation, this study uses Data Envelopment Analysis (DEA) to evaluate the effectiveness of the policy project and propose its evaluation results. Also, we want to derive the weight calculation for utilizing DEA by using AHP method. Results - This study's results were derived from the input and output variables, so instead of qualitative analysis, the conclusion was drawn out from the quantitative analysis. Through this quantitative analysis method, we had an opportunity to identify the characteristics of each site by each year. Conclusions - It is believed that the reliability of the results can be further improved if the qualitative part can be supplemented its unique characteristics of the model which only considers the simple quantitative aspect. Further studies should be undertaken as these sectors are expected to draw out fruitful research conclusion when these aspects were supplemented additionally, so continuous additional study is essential.
