컴퓨팅 성능향상과 장비의 증가는 전력소비의 증가로 이어져 데이터센터 경영자에게 운영경비의 증가로 피할 수 없는 중요한 문제가 되었다. 그래서 미국의 데이터센터에서는 에너지 효율화 지수인 PUE(Power Usage Effectiveness)를 표준지수로 정하고 에너지소비를 관리하고 있다. 데이터센터에서 소비되는 에너지에서 IT부문과 비IT부문의 에너지 소비비율은 50:50 비율이다. IT장비는 처음 도입 시 에너지 효율적인 장비를 도입하면 컴퓨터 운영상에서 에너지를 절감할 기회는 많지가 않지만, 비IT부문은 설비운영적인 측면으로 안정성을 고려하면서 동시에 효율적인 운영환경을 유지하는 것이 가능하다. 본 문서에서는 비IT부문에서 전산실 장비의 열복도-냉복도 분리 배치가 에너지 절감효과가 어느 정도인지 실험을 하였으며, 그 실험결과를 기술하였다.

최근 정보통신기술의 발전과 세계화의 진전으로 IT제조업의 생산 효율화를 통한 비용절감의 방안으로 각 생산공정의 국제분업이 이루어지게 되었다. 국제분업을 통해 국가는 비교우위의 생산요소에 집적을 통해 효율화를 이루게 된다. 하지만 이러한 국제분업을 통해 기술의 양극화 현상이 나타나게 되고 국제분업구조에서 기술중진국의 비교우위부문의 확보가 새로운 과제로 부상되었다. 따라서 기술중 진국이 장기적으로 국제분업구조에서 기술부문의 비교우위확보를 위해 민간부문과 공공부문에서 동시에 이루어져야한다.

IT분야의 벤처기업 창업 활성화의 일환으로 정보통신부는 '98년도부터 투자 사업을 통해 IT전문투자조합에 출자해 오고 있다. 이글에서는 정보통신부가 출자한 IT전문투자조합의 운영 현황을 구체적으로 살펴보고, 최근까지 IT전문투자 조합을 통해 이루어진 투자 내역을 토대로 지난 4년간 국내 벤처캐피탈의 IT부문 벤처 투자 동향을 분석해 보았다. 이번글은 아직 벤처캐피탈 투자에 대한 정보가 부족한 상황에서 IT부분을 중심으로 과거 국내 밴처 캐피탈의 투자에 대한 분석을 수행했다는 점에서 의의를 지닌다 이글을 통해 향후 IT전문 투자조합 및 국내 벤처캐피탈의 투자조합 운영에 있어 개선점을 제시해 국내 벤처캐피탈의 선진화에 기여하고자 한다.

최근 들어 행정기관의 정보 기술 분야에 막대한 예산이 투입되면서 공공부문의 정보화가 빠른 속도로 전개되고 있다. 이러한 공공부문의 정보화를 위한 노력들이 과연 어떤 효과를 가져오고 있는지에 대한 연구의 필요성이 제기된다. 본 연구에서는 성과측정을 위한 척도로서 행정기관 IT생산성 지수를 산출하기 위한 지표를 선정하고 그에 따라 지수를 산정하여 이를 연도별로 비교해 보고자 한다. 행정의 업무효율성이라는 측면에서 IT생산성은 3년 동안 꾸준히 증가추세를 보인 반면, 대민서비스를 통한 고객만족도를 생산성개념에 추가시켰을 때는 2001년의 생산성지수가 전년도에 비해 약간 저하되었으며, 2002년에는 증가추세를 나타내고 있다.

This study is intended to examine the types of U-public service that can be introduced to the public sector by making an empirical analysis on Chungju City public officials. Specially, to analyze the public officials' recognition of the types of ubiquitous public service that can be introduced to the public sector, this study investigates the utility and necessity of ubiquitous information technology when making use of it in terms of administrative concepts. To achieve study purpose, this study examines what type of U-public service is highly likely to be applied and basically has to be applied when ubiquitous information technology is applied to the current environment of Chungju City in stages.

Climate change has influenced on various sectors including ecosystem, water resource, natural hazards and health and so on. Thus, it is essential to more accurately assess climate change impact and prepare adaptation strategy. However, it is difficult to assess for climate change impact on various sectors with integrated form due to various data format by sectors. In this study, we prepared criteria and indicators for assessing climate change impact and integrated GIS based data which in correspond to indicators based on spatio-temporal information using GIS. Finally we suggest a guideline to assess vulnerability of each sectors to climate change based on integrated spatio-temporal information.

Recently, United Nations found that 38% of global carbon emissions are generated in the building sector, surpassing other industries (32%) and transportation (23%), and ESG is actively used as a way to reduce carbon emissions in the building sector, led by overseas advanced countries. In Korea, as the National Pension Service announced "Consider ESG with more than 50% of investment assets" this year, the move to introduce ESG in the building sector is accelerating, centering on construction companies and asset management companies. However, as the domestic ESG evaluation system is still mainly focused on corporate governance and social responsibility, interest in the environmental sector is lagging behind that of advanced countries. As ESG in the building sector is expected to grow rapidly over the next 10 years, I would like to suggest the following development directions. The first is the expansion of the incentive system. In order for the government to successfully implement policies related to ESG in the building sector, incentive system such as tax reduction and building standards should be expanded further than now in addition to negative systems such as rent restrictions and punishment taxes due to regulatory violations. Second, standardized ESG standards are established. Rather than creating an independent Korean ESG standard that is far from global standards, it is necessary to organize the common parts of global standards and evaluation methods and create and provide guidelines in the form of standard textbooks that can be used equally by all stakeholders. Third, it is an effort to link ESG in the building sector with Digital Transformation(DX). This is because actual energy savings and carbon emission reduction can be realized only when the operation method of the building sector, which is operated mainly by manpower, is digitalized and converted to an intelligent way.

This study aims to suggest methods for improving innovation capability in Daegu-Gyeongbuk's mobile industry. Before offering suggestions, it analyzes the characteristics of technological innovation based on the mobile industry's value chain in Daegu-Gyeongbuk in relation to R&D workforce, R&D expenditures, and R&D networks. Support for R&D workforce in the Daegu-Gyeongbuk's mobile industry is concentrated in the mobile device and contents sectors. In addition, it is difficult for companies to finance R&D expenditures because most are SMEs, except for some large enterprises in the mobile device sector. R&D networks are structured mainly inside of companies, and linkages among universities, research institutes, and supporting institutes are weak in all sectors. To strengthen the innovation capability in Daegu-Gyeongbuk's mobile industry, therefore, human resource projects should be dispersed, and financial support should also be spread across value chain sectors rather than concentrated. Aside from this, a place for industry, academia, institutes, and government to build and enhance innovative networks should be created in all sectors.

This paper was reclassified industries related to the 4th industrial revolution into manufacturing, information and communication services, finance and insurance services, and science and technology services by comparing the industry association table with the Korean standard industry classification. And the economic ripple effect was analyzed by exogenizing the four sectors of the industry using a demand-driven model. The wholesale and retail and product brokerage services were measured to be large in the manufacturing, information communication services, and science technology service sector according as a result of analysis of the production inducement effect, added value inducement effect, and employment inducement effect. And the financial and insurance services were analyzed to be large in the financial and insurance services sector. The import inducement effect was analyzed to be the largest in all sectors of the fourth industry. As a result of the forward and backward linkage effect, it was confirmed that the manufacturing and the information communication services sector were the intermediate primary production type sensitive to economic fluctuations. Also it was confirmed that the financial and insurance services and the science technology services sector were the final primary production type.

This study considered regional differences in the university-industry collaboration of Korean universities and performed cluster analysis to identify the spatial range with high university-industry collaboration connectivity. By university establishment type, it was found that the university-industry collaboration capacity of the major national university was superior overall, especially in the technology transfer & commercialization sector and the infrastructure sector, compared to private universities and general national universities. The spatial pattern of university-industry collaboration capacity showed relatively clear differences by city and province. In terms of university-industry collaboration capacity by sector, it was confirmed that the regional gap was not large in the talent training sector and the infrastructure sector, but the regional gap was relatively large in the technology transfer & commercialization sector and the start-up sector. As a result of the cluster analysis to identify a spatial range with high connectivity in terms of similarity and spatial proximity of university-industry collaboration patterns, it is divided into 15 clusters. It is found that most of major national universities are included in one of 15 clusters where all sectors of university-industry collaboration are strong. Therefore, as a policy measure to achieve regional innovative growth through enhancing the effectiveness of university-industry collaboration, we propose the establishment of a hub & spoke network-type collaboration system in which a major national university acts as a hub and nearby local universities play a spoke role.
