This study attempts feasibility analysis of cataloging outsourcing. The economic analysis model based on information economics categorizes the benefit into direct benefit and value linking. We measure direct benefit by cost savings and cost avoidance, value linking by the degree of improvement in cataloging quality The results show that there is no feasibility overall, because librarians spent more time to control the quality due to vendor's lack of professionalism, resulting little effect on cost savings. When cataloging outsourcing is forcibly used under the economically infeasible condition, it is impossible to achieve the basic purpose of operating cost savings and improvement of service function.

The inter-industrial inducement effects of the korean railway services on the output, value-added, imports of the 403 industrial sectors of the korean economy have been computed by the input-output analysis technique utilizing the 2003 Input-Output Tables, which was published most recently in April 2007 by the Bank of Korea. The korean railway service industry produced \2,766 billion worth of passenger and freight railroad services in the 2003 year, and it has induced \1,701 billion worth of output, \781 billion worth of value-added, and \580 billion worth of imports of the korean industry as a whole. The energy sector industries such as diesel fuel, thermal power generation, nuclear power generation, crude oil, liquid natural gas, bituminous coal, liquid propane gas have been most affected by the korean railway services. Other industries mainly affected by the korean railway services include railroad car manufacturing, cleaning and decontamination, medical and health service, machinery equipment and rental, construction and maintenance, transportation related services, business R&D, property insurance, and telecommunication.

So far, the phenomenon of "electrification" has been deepened in Korean industry and especially direct heating energy which accounted for 44.0%(2010) of total energy consumed in Korean manufacturing has been significantly electrified. This paper decomposed electricity consumption for direct heating in Korean manufacturing from 1992 to 2012 using LMDI(Log Mean Divisia Index). This paper includes 4 different factors such as electricity proportion effect, direct heating proportion effect, energy intensity effect and added value effect. And this paper compared the consumption pattern by business type. As results, electricity proportion effect had contributed the most to the increase of electricity consumption for direct heating in Korean manufacturing. And Petrol-Chemical and Iron & Steel had the most electrification of direct heating.

This study examined economic ripple effect of marine transport and port industry using Input-Output Tables. The results of the study are summarized as follows: first, in 2005 production inducement coefficients of harbour facilities was the highest(1.958), followed by coast and inland water transportation(1.857), load and unload(1.842), other transportation services(1.768), storage and warehouse(1.676), water transportation assistant services(1.422), and outport transportation (1.283). Second, value added inducement coefficient of water transportation assistant services was the highest(0.924), followed by load and unload, storage and warehouse(0.902), other transportation services(0.885), harbor facilities(0.832), coast and inland water transportation (0.752), and outport transportation(0.258). Third, import inducement coefficient of outport transportation was the highest(0.742), followed by coast and inland water transportation, harbor facilities, other transportation services, load and unload, storage and warehouse, and water transportation assistance services. Fourth, indexes of the sensitivity of dispersion of other transportation services and load and unload were 1.125 and 0.882 respectively while those of harbor facilities and outport transportation were 0.514. Indexes of power of dispersion of harbor facilities, coast and inland water transportation, load and unload, and other transportation services were the highest, respectively 1.006, 0.954, 0.946, and 0.908 while that of outport transportation was low, 0.659.

Agar, one of the most abundant marine products has not been utilized extensively because of low level of processing technology in Korea. This research was carried out to improve the utilization of agar and consequent increase in profit. Antibacterial activity of agarooligosaccharides were evaluated against bacteria causing putrefaction and flood poisoning. Addition of 0.4% agarooligosaccharides showed antibacterial activity toward Staphylococcus aureus and Escherichia coli O157:H7; furthermore, autoclave treatment of agarooligosaccharides solution enhanced the antibacterial activity. Agarooligosaccharides showed high stability against the pH change. Addition of amino acid(alanine, lysine, glycine, phenylalanine) in agarooligosaccharides solution enhanced antibacterial activity in E. coli O157:H7, Streptococcus mutans and Staphylococcus aureus.

항공기산업은 고부가가치, 높은 기술파급효과 등의 경제적 요인 이외에도 국방 등의 전략적 요구 및 국가이미지의 대내외적 제고 등 요인을 동시에 갖고 있는 첨단의 전략산업일뿐 아니라 개발성과가 불확실하고, 수요의 독점성과 기술의 복합성, 자본 및 경험 집약성 등의 요인으로 인해 육성하기 어려운 산업이다. 우리나라에서의 항공기산업은 자동차, 철강, 반도체 등 세계적인 선도 산업에 비해 아직은 그 산업의 성과가 충분치 못한 실정이다. 그 이유로는 수요의 영세성과 불연속성, 고립된 산업 구조 및 그로 인한 낮은 산업파급효과와 낮은 부가가치구조, 취약한 부품산업 등의 여러요인이 거론되고 있다. 그러나 이러한 수요와 공급 및 기술과 산업구조 등의 여러측면을 조정하고 통합하는 정부의 역할과 기능이 더욱 중요한 요인이라 하겠다. 공군력 증강과 장기 경제발전을 위해 우리나라 항공기산업의 현재 수준을 한 단계 도약시키기 위해서는 우선 산업의 명확한 비전과 발전전략의 제시와 적절한 사업의 선정의 효과적인 추진이 중요할 것이다. 적절한 사업의 하나로는 국내의 축적된 기술과 생산기반을 활용하여 우리나라가 주도적으로 개발/생산할 수 있는 적절하게 통제된 규모의 중급항공기 개발사업을 들 수 있겠다. 이를 위해서는 체계적이고도 통합된 정부의 역할이 가장 긴요하다. 특히 산업이 가지고 있는 공공성, 전략성 및 복합성 등의 특성을 감안할 때, 우리나라 항공기산업의 성공적인 발전을 통한 장기적인 공군력 증대에의 기여를 위해서는 수요, 기술, 생산 및 관리를 효과적으로 조정하고 통괄하되, 책임소재가 명확하게 식별될 수 있도록 수요부처 중심의 추진주체로서의 정부의 통합된 기능과 역할이 특히 강조된다 하겠다.

There has been a rising interest in cultural content industry as it may be one of the future growth engines to boost the economy of Korea. Cultural content industry has demonstrated high growth rates compared to any other industries. In the case of Busan, a variety of cultural content industry around games are being developed; however objective and quantitative research on the economic impact of this industry is inadequate. This study, therefore, analyses the economic impact of the cultural content industry of Busan in order to create a plan that would enhance the value of existing cultural contents.

This paper develops a framework for analyzing the effectiveness of broadband network from the value chain view. The value chain of broadband network is composed of activities such as broadband network building, application/equipments development, information systems utilization. The effectiveness from the interaction between these activities are defined as the effectiveness of informatization(private and public sector) and the effectiveness of IT Industry(effects on production on inducement of broadband carriers, IT equipments and service market creation, online digital contents market creation). For testing its real-world applicability, a case study is performed on the broadband network of Korea and the effectiveness of the framework for analyzing the effectiveness of broadband network is demonstrated.

In this paper, we investigate the national effects of the ubiquitous industry(UI) for a u-Korea(ubiquitous Korea) project. As the UI has now been playing the more and more important role in Korean economy, it will be very appropriate to provide the policy makers with the accurate and reliable implications regarding the role of UI in the national economy. This paper applies the interindustry analysis to examine the impact of UI under the unique situation of Korea. To do this, we use the Input-Output Table published by the Bank of Korea in 2000. Our results shows that the economic effects of UI on the production-inducing, value added-inducing, export & import-inducing and employment-inducing in Korea will approximately be 240 trillion won from 2005 through 2010.
