The purpose of this study is to present the directivity of outcome management through the analysis of public library operations in Seoul. For this purpose, author evaluated the public library policies by linking the 「Metropolitan Comprehensive Library Advancement Plan 2018~2022」 and 「The Third Comprehensive Library Advancement Plan: 2020 implementation plan」 and compiled to draw up the issue of policy development on the awareness of public library services by Seoul citizens. Nest, author analyzed and compared the core infrastructure, collection services, programs and activities of 173 public libraries in 25 local governments. Based on these results, author suggested the directivity of outcome management as follow. All public libraries in Seoul must emphasize the development scope and management methods of the performance indicators. For outcome management, this study emphasized building a strategy planning with the development procedures of performance indicators, categorizing outcome management indicators, developing user-centered indicators, and improving qualitative indicators. As there is a possibility that the quality of services expressed in the output may deteriorate due to the failure of the physical input indicators, it is necessary to strengthen the input and encourage the resolution of the service gap by establishing a performance management system to logically explain the relevance or causal relationship between these indicators.

This paper analyse the economic inducement effects of aviation industry using Input-Output Model. For measuring economic inducement effects of aviation industry on korean economy, this paper divides air transport industry as two - manufacturing industry and service industry. we also use Input-Output Table of year 1990 through 2003 from Bank of Korea. Empirical results tells that aviation manufacturing industry have high product inducement effects to national economy although its low value-added coefficient such as 0.486 for aviation manufacturing industry and 0.447 for aviation service industry. public R&D doesn't have much effect to each of aviation industries.

This paper examines the process of embodied technology spillovers in terms of supply and demand of technology For the purpose, this paper develops a consistent framework to estimate intersectoral R&D spillovers, and to pinpoint the sectors that are the most important for innovative activities and the sectors that produce most technologically intensive products. Based on an input-output framework, the technology intensity of fourteen sectors and the interaction between the sectors in terms of technology spillovers are measured. The results indicate that knowledge-based service sectors are highly supply-pulling and value-additive, but low in terms of employments. The study found that computer services, telecommunications, technology services, and art-related services are the most technology intensive sectors.

유지보수 내용에 대한 사용자의 의견 수렴에 대한 요구사항 정의나 각 단계별 산출물 등에 대한 표준지표 등이 존재하지 않아 각각의 사업이나 시스템 별로 유지보수를 수행할 때마다 경험만을 기반으로 한 정성적인 작업이 이루어지게 되어, 유지보수 작업과 비용이 초과로 투입되는 등의 문제점들이 발생하였다. 이런 문제를 해결하고 유지보수성을 향상시키기 위해 유지보수에 대한 서비스 수준의 정확한 문제점 파악과 발생 문제점들에 대한 분석이 필요하게 되었다. 본 논문에서는 기존의 표준 유지보수절차에 대해 연구하고 SLA를 적용한 유지보수 프로세스인 서비스 지향 유지보수 프로세스를 제시하고자 한다.

Existing researches on tax efficiency of environmental taxes mostly focuses on taxes imposed on the consumption process of the final output, or goods that create pollution during the input process of intermediate goods. The assumption here is that there is a significant relation between the consumption of polluting goods and the pollution itself. However, in reality they are not identical. This signifies that the above assumption may distort the actual results. This study classifies environmental tax into two different forms, output tax and emission tax. Theformer is the tax that is imposed on the consumption of polluting goods, while the latter is directly levied onto the emission of pollution. It then compares the efficiency of these taxes through the computational general equilibrium simulations. After analyzing the simulation, it was proven that the direct imposition on pollution, or environmental tax as emission tax, was more effective in terms of tax efficiency. Furthermore, these results were revealed as irrelevant to the assumption of homotheticity in utility function. Thus, if market-distortionary tax already exist, then the effectiveness of revenue neutral environmental tax reform will be sensitive to the assumption of homotheticity for utility function. However, environmental taxes as emission taxes have been shown to be more effective in tax efficiency than output taxes.

In this study, performance and economic analysis of 500 MWe coal-fired power plant with $CO_{2}$ capture process was performed. For this purpose, chemical absorption method which is commercially available and most suitable for thermal power plant was studied and a criteria for technical and economic assessment of power plants suggested by IEA Greenhouse Gas R&D Programme was used. And we performed the sensitivity analysis focused on regeneration energy which exceed half of the total capture energy. Based on MEA(Monoethanoleamine) as a main chemical solvent and 3.31 GJ/ton$CO_{2}$ regeneration energy in the stripper, net power efficiency was reduced from 41.0% (no capture) to 31.6%(with capture) and the cost of $CO_{2}$ avoided was estimated 43.3 $/ton$CO_{2}$. And in case of 2.0 GJ/ton$CO_{2}$ regeneration energy, the cost of $CO_{2}$ avoided was calculated as 36.7 $/ton$CO_{2}$.

Since 2013, Korea has allocated significant budgets and manpower nationwide to prevent the spread of pine wilt disease and to reduce damage. As a result, the number of damaged trees decreased from 2.18 million in 2014 to 310,000 in 2021. However, the damage has increased again since then. Despite the overall decrease in the number of damaged trees, the scope of the damage continues to expand every year. Previous studies have develope In order to judge the control performance, a quantitative control performance analysis method to objectively evaluate control performance. This method takes into consideration two factors-quantity change and the change in the damage area, which is an area factor. This approach provides a more comprehensive assessment than the control guidelines that only suggest changes in damage grade based on the volume of damaged trees. The expansion of the damage range is also an important factor in analyzing control performance, but previous studies have not reflected this. Therefore, this study calculates the change in the distance of the pine wilt disease boundary area for Gyeongsangbuk-do, where changes in the damage range can easily be observed from year to year. The study then creates application criteria and coefficients and uses them to improves control performance index calculation formula. As a result, it was possible to calculate a quantitative analysis of the control performance, taking into account the changes in the damage range. When the improved formula was applied to 26 cities, counties, and districts in Gyeongsangbuk-do, it slightly decreased or increased compared to the existing calculation formula. This confirmed that the control performance index can change from a positive value (+), indicating increased damage, to a negative value (-), indicating reduced damage.

Urban railway started its operation in August 15, 1978 in Korea. Nowadays, it is being operated in Seoul, Busan, Incheon, Deagu, GwangJu, and Daejeon, and it is playing a major role in mass transportation. Urban railways can provide rapid and convenient transportation to citizens in eco-friendly and energy saving way. However, urban railway operating organizations have been in financially difficult conditions due to the enormous debts borrowed for the construction of railways. Urban railway operating organizations are under pressure to improve its difficult financial conditions through the efficient management of the organization. The management and operation efficiency of urban railway organizations have been evaluated since 1993 by Ministry of Public Administration and Safety to make those organizations more competitive, responsible and efficient. However there are some limitations in evaluation since they do not reflect the relative size of organizations, relative newness of facilities, etc so that it's not objective and loses fairness. This study proposes an improved method for the evaluation of safety.
