This study investigates how characteristics in the value-chain industrial cluster affect the R&D investment and the output of firms in each industries. For this, we try to extract the inter-industrial networking structure from the input-output table in which 17 manufacturing sectors are included. In particular, we will give shape to the "unit structure" which shows the intermediary flows of goods and services between industries in order to get an unit of final demand in a certain industry. Using this "unit structure", we can try the inter-industrial networking analysis and get some indices of centrality and centralization related to the characteristics of each industries in the value-chain industrial cluster. The results show that the centrality in the value-chain industrial cluster does not have any consequence for the R&D investment and the output in each industries. However, there is a correlation between the centralization in the value-chain industrial cluster and the R&D investment and the output of firms in each industries. These results may be very suggestive in bringing up a new frame of industrial cluster policy in a macro level.

This paper quantitatively analyzes the investment performance of the environmental improvement fund focusing on the sales effect and the housing benefit effect. The analysis of this study focused on the effects of sales and housing benefits for completed business sites among the business sites supported by the Environmental Improvement Fund. The analysis results are as follows. First, it appears that the sales effect of the completed workplace is effective compared to the amount of investment, so it seems that the purpose of industrial integration of the environment improvement fund is being achieved. Second, it was found that there are variations by workplace and region in housing benefits. This seems to be due to the fact that profitability can be neglected by reflecting the characteristics of residential facilities built by private businesses. The Environmental Improvement Fund is a policy fund that pursues both profitability and publicity. Therefore, it is necessary to transform the structure of the fund to expand support for industrial infrastructure with high publicity. To this end, it is necessary to establish a long-term management plan that equitably considers the profitability and publicity of the environmental improvement fund.

The primary purpose of this study is to develop an automation tool capable of converting the specification of structured analysis into that of structured design. Structured Analysis and Structured Design Language (SASDL) is a computer-aided description language based on ERA model and particulariged by ISLDM/SEM. The automation tool utilizes the specifications of data flow diagram described in SASDL to produce their corresponding SASDL specification of structure chart. The main idea behind the automatic conversion process is to categorize the bubbles in data flow diagram and to determine the positions of the bubbles in structure chart according to their categories and the relative locations in data flow diagram. To make the problem into manageable size, the whole system is broken down into separate parts called activity units. A great deal of manual jobs, such as checking processes leveling, checking data derivation of processes, deriving structure chart from data flow diagram, checking any inconsistency between data flow diagram and structure chart and so forth, can be automated by using SASDL and conversion tool. The specification of structure chart derived by conversion tool may be used in an initial step of design to be refined by SASDL users.

The results of diagnostics and analysis of an industrial hall located on the premises of a thermal power plant severely damaged by fire are presented in the paper. The comprehensive failure-related diagnostics, non-destructive and destructive tests of steel and concrete materials, geodetic surveying of selected structural members, numerical modelling, static analysis and reliability assessment were focused on two basic goals: The determination of the current technical condition of the load bearing structure and the assessment of its post fire resistance as well as assessing the degree of damage and subsequent design of reconstruction measures and arrangements which would enable the safe and reliable use of the building. The current mechanical properties of the steel material obtained from the tests and measured geometric characteristics of the structural members with imperfections were employed in finite element models to study the post-fire behaviour of the structure. In order to compare the behaviour of the numerically modelled steel roof truss, subjected to the effects of fire, with the real post-fire response of the damaged structure theoretically obtained resistance, critical temperature and the time at which the structure no longer meets the required reliability criteria under its given loading are compared with real values. A very good agreement between the simulated results and real characteristics of the structure after the fire was observed.

본 연구는 거시경제적 변동성(macroeconomic volatility)이 국가마다 다르게 나타나는 현상의 원인을 산업구조적 차원에서 실증분석을 통해 찾아보려는 시도이다. 특히 우리나라 경제에서 서비스산업이 차지하는 역할에 주목하여, 서비스산업이 경기변동성에 미치는 영향을 국내적인 산업구조 측면과 국가 간 비교를 통해 분석하였다. 분석 결과, 우리나라의 경기 변동성은 국가위험도를 중심으로 과거에 비해 크게 개선되었으나 여전히 대내외적 충격의 영향에 노출되어 있으며, 이는 제조업 중심의 산업구조적 특성에 기인한 것으로 판단할 수 있다. 이러한 산업구조하에서는 우리 경제가 대외부문 충격(global sectoral shock)으로 인한 거시경제적 변동에 지속적으로 노출될 수밖에 없다는 것을 의미하며, 구조적으로 나타나는 변동요인을 완화시키기 위해서는 서비스업이 대부분을 차지하고 있는 비교역재 부문이 상대적으로 활성화되어야 함을 시사하고 있다.

This Study intends to analysis what 3 factors, which are indices of Capital, Labor and Distribution, really affect to Value-Added Productivity through Statistical Analysis. For this, We selected 12 indices of Value-Added from the edition of 'Annual report of Korean companies' published in 'Korea Investors Service., Inc', especially in parts of Chemicals and Chemical products of total 85 companies. Using this data, Multivariate Statistical Analysis such as Principal Component Analysis, Factor Analysis, Covariance Structure Analysis is taken for modeling the effect of 3 factor(Labor Productivity, Capital Productivity and the Index of Distribution) on Value-Added Productivity.

This study, in order to complement instability of analysis result stemming from the choice between reference point and comparison point which is pointed out as the defect of shift-share analysis, conducted shift-share analysis using Gross Regional Domestic Product (GRDP) trend of Geumgang area, Chungcheongnam-do for the period from 2000 to 2011. As a result of the analysis, (1) industries that had both the positive Regional Share Effect (RSE) and Industrial Mixed Effect (IME) were service industries such as manufacturing industry, electricity gas, transportation industry, art, etc., which are positively influencing the regional industry. (2) industries that had both the negative RSE and IME were other service industries such as wholesale and retail businesses, lodging industry, food industry, real estate business and leasing service, business service industry, public administration, etc., which provide basic livelihood services for the residents. (3) industries that had the positive RSE and negative IME were agriculture, forestry and fishery industry, mining industry, construction industry, and educational service industry. (4) industries that had the negative RSE and positive IME were info-communications industry, financial and insurance businesses, health industry, etc.

본 연구는 광역적 산업클러스터의 관점에서 영남지역 기계금속산업클러스터의 형성과정과 연계 구조를 설명하고자 하였다. 그간의 국내외 연구들에서 광역적 산업클러스터에 대한 이론적, 경험적 연구가 미흡한 실정이었다면, 이론적인 분석과 함께 영남지역 기계금속산업클러스터를 대상으로 구체적인 사례연구를 시도한 것이다. 이를 위해 먼저 광역적 산업클러스터의 형성과정 및 구조에 관한 모델을 이론적으로 검토하였다. 광역적 산업클러스터의 형성과정은 외연확산형과 연계 심화형 그리고 복합형으로 구분될 수 있는 것으로 사료된다. 그리고 광역적 산업클러스터의 내부 구조는 다양하며, 흔히 광역클러스터와 그 하위에 존재하는 개별 산업클러스터가 중층적 (혹은 다층적) 구조를 형성하고 있는 것으로 분석되었다. 남지역에서 광역적 산업클러스터가 형성된 과정을 살펴보면 거시적 관점에서 개별 산업도시(산업클러스터)들이 점차 연계를 심화한 계심화형으로 분류할 수 있다. 그러나 부산이나 대구 대도시권에서 발생한 제조업 교외화 과정에서 산업클러스터의 외연 확산이 있었으며, 그러한 점에서 보다 엄격히 말한다면 연계심화형에 부분적으로 외연확산형이 혼합된 복합형이라고 할 것이다. 영남지역의 광역적 기계금속산업클러스터는 공간적 차원에서 중층적 구조를 가지고 있는 것으로 확인 되었다. 영남지역 대부분을 포함하는 광역 클러스터가 작동하는 한편으로, 그 하위에는 포항, 울산, 창원, 거제 등 개별 산업클러스터들이 독자적 단위로 존립하고 있는 것이다.

일찍이 복지국가 발달에 산업화가 중요한 영향을 끼친다는 산업화 이론은 복지국가 발달을 설명하는 주요한 이론으로 자리매김해 왔다. 그러나 산업화 이론은 산업화가 발달한 서구 선진국가들이라 하더라도 공공복지의 규모는 상대적으로 약하다는 비판에 직면하였고, 이러한 한계를 보완, 설명하기 위해 이익집단들이 선거 경쟁에서 승리하기 위한 전략으로 공공부문의 복지가 확대될 수 있었다는 민주주의 이론, 복지국가를 요구하는 노조와 좌파정당들의 힘이 강화될 때, 복지국가 또한 발달할 수 있었다는 권력자원 이론 등이 부각되었다. 본 연구는 복지국가 발달을 설명하기 위한 새로운 시도로서 복지국가의 발달에 영향을 주는 기존 이론들에 따른 요인들 외에 산업구조에 따른 요인들을 추가하여 퍼지셋 질적비교 분석을 수행하였다. 분석결과 복지국가발달에 있어 기존이론 외에 제조업의 비중 또한 복지국가 발전의 중요 요소로서 작용할 수 있다는 점을 발견할 수 있었다. 이러한 분석결과는 산업화 이론, 민주주의와 선거경쟁이론, 권력자원 등과 같은 복지국가를 설명하는 기존이론 뿐만 아니라 제조업 비중과 같은 산업구조 또한 복지국가 발달에 영향을 줄 수 있는 요소임을 시사하고 있다.
