The Korean government implemented 259 road projects from 2004 to 2007, valued at $18.4 billion. Change orders of these road projects occurred 8,973 times and, subsequently, caused significant increases in the cost of the projects, approximately up to $4.2 billion (22.8% of the initial budget). These significant problems of huge change orders require a more workable control system for budget management whereas the effectiveness of the government's control is still not satisfied. However, previous approaches and studies mostly limited their analyses to simply classifying the causes of the change orders. This paper investigates the real frequency and cost impacts incurred by each cause of a change order, primarily based on 218 road projects in Korea. The paper then identifies the attributes of change orders through a survey of 204 project participants in that those sources were inevitable or avoided if properly managed. The causes of the change orders are further analyzed with analysis of variance (ANOVA) in connection with contract volume, bid award rate, the contractor's capacity to perform, and the design company's capacity. This study found that if the contract volume is smaller, then the possibility of change orders is higher. Interestingly, if the bid award rate is less than 67.5%, it signifies the highest rate of change orders. In addition, the contractors whose construction ability is assessed as the top-ranked group showed the lowest change order rates. With these results, this paper provides the preventive guidelines for reducing the likelihood of change orders.

정부기관, 지자체 및 공공기관의 입 낙찰제 운용과정에서 예정가격은 낙찰자를 선정하기 위한 기준금액이 되므로 발주자와 입찰자에게 아주 중요한 요소이다. 예정가격이 높으면 입찰자에게 불리해지고 낮으면 낙찰자에게 불리해지기 때문이다. 그러므로 대부분의 발주기관들이 예정가격을 공정하고 투명하게 결정하기 위해서 복수예비가격을 사용하여 예정가격을 결정하는 방식을 채택하고 있다. 본 연구에서는 예비가격 15개를 추출(복수예비가격 생성)하는 방법과, 15개의 예비가격 중에서 4개를 추출(예비가격 추첨)하는 방법에 따라 예정가격이 어떻게 달라지는지를 다룬다. 이를 위해 여러 가지 복수예비가격 결정방식별로 컴퓨터 시뮬레이션을 통해 예정가격을 분석한다. 분석을 통해 얻은 결과는 다음과 같다: 첫째, 복수예비가격의 생성범위를 15개로 분할하고 각 구간에서 4개의 예비가격을 추첨하는 방식이 전체 범위에서 예비가격을 4개 무작위로 추첨하는 방식보다는 예정가격이 기초금액 근처에서 형성될 가능성이 높다. 둘째, 복수예비가격의 생성범위를 15개로 분할하고 각 구간에서 무작위로 예비가격을 추첨하는 경우, 발주자 입장에서는 100%보다 큰 범위에서 7개, 아래에서 8개의 구간으로 나누는 방식이, 입찰자 입장에서는 100%보다 큰 범위에서 8개, 아래에서 7개의 구간으로 나누는 방식이 다소 유리한 방식이다. 셋째, 기초금액 기준으로 위와 아래에서 구간의 수를 달리 할 경우라도, 100% 위의 구간에서 2개, 아래 구간에서 2개로 나누어 예비가격을 추첨하게 되면, 예정가격의 평균이 기초금액과 같아지며 표준편차도 15개 구간에서 4개의 예비가격을 무작위로 추첨할 경우보다 크게 작아진다.

The ever-increasing government budget constraints have led to a continued decline in the increase rate for defense spending, and the government's 5-year National Fiscal Management Plan has served to reinforce the verification and validation procedures for the Force Improvement Programs (FIP) budget requirements and performance. Additionally, as large programs are controlled in accordance with the Total Program Cost Management Guidelines, timely and credible feasibility study and performance measurement need to be conducted. Due to these internal and external circumstances, needs have surged for feasibility and economic effectiveness study for big ticket projects in the FIP sector, with an increasing number of studies conducted by external research institutes. However, questions have been raised regarding the credibility and thoroughness of the program analyses performed by these research institutes due to various restrictions. This paper analyzes and identifies the structural limitations and problems using a systems thinking approach, and examines the systemic characteristics of the program analysis system. It also presents policy intervention recommendations based on the theory of systems thinking, a method to regularize and reinforce the program analysis system. Policy interventions recommended to ensure alignment of the external studies to the clear analysis objectives and resolve the bottlenecks in the external analysis include training those in charge of external study commissioning for a short term intervention, and increasing the number of research institutes and consulting agencies utilizing analysis and evaluation experts who transition to the private sector from the military for a long term intervention. additionally presented are strategies and policy alternatives to best utilize these policy interventions. They will contribute to the stable funding of Force Improvement Programs and efficient utilization of defense budget.

The enormous budget of government and manpower are invested to the government funded institutes every year. The R&D investment focused on input has to be turned toward the investment based on the effectiveness of R&D activities. Measuring the efficiency of research activities is required in order to evaluate the effectiveness of R&D investment in these institutes. The purpose of this paper is to evaluate the relative efficiency of research activities performed in 19 government funded research institutes. CCR/BCC model and DEA/AR model were applied to get the relative efficiency of 19 institutes. Assurance regions for the weight of output attributes were obtained by using the underlined concept of the analytic hierarchy process (AHP). We used input and output data items describing research activity of 19 government funded research institutes. The results of this study are expected to become a basis of the R&D investment decision of the government.

PURPOSES : This study aimed to evaluate the performance of pavement management works and to develop a function for estimating the level of service (LOS) and cost of service (COS) for the systematic and quantitative management of pavement performance in the public sector. METHODS : The International Roughness Index (IRI) was used as the performance index for pavement management. Long-term pavement performance data for a period of 7 years (2007-2014) collected by the National Highway Pavement Management System and historical maintenance budget data published by the South Korean government were used to develop the LOS-COS function. Based on the function, a model for estimating the appropriate budget as well as the network conditions was suggested. RESULTS : There was high degree of correlation between pavement performance and the investment level (R = - 0.74). The developed LOS-COS function suggested that the unit cost to improve the network IRI to 1 m/km was 32.6 billion KRW. Further, the maintenance costs normalized with respect to the LOS levels were LOS-A = 88.2 billion KRW, LOS-B = 55.6 billion KRW, and LOS-C = 23.0 billion KRW. CONCLUSIONS : This study proposes a simple way of developing a LOS-COS function. It also shows how to develop a network budget demand and condition estimation model using the LOS-COS function. In addition, it is the first attempt to evaluate the road maintenance budget in South Korea. It is expected that these results will help in the negotiations between the road managers and budget makers.

국가 R&D사업은 적절한 예산 규모 산정이 어렵기 때문에 참고 가능한 해당 사업의 성과 및 평가정보가 적시에 지원될 경우 판단의 오류를 최소화 할 수 있을 것으로 기대할 수 있다. 그러나 현실적으로는 국가 R&D사업에 대한 성과평가 결과가 의도한 대로 충분히 활용되지 못하고 있는 실정인데, 그 이유로는 크게 두 가지 문제점을 들 수 있다. 첫째, 국가 R&D사업의 성과 및 평가 정보와 관련 예산정보가 적시에 연계 활용되지 못하고 있다. 둘째, 이를 지원하는 시스템간의 연계가 구현되어 있지 않다. 따라서 본 연구에서는 국가 R&D사업의 현황 분석을 신정부 출범 이전과 이후의 제도적, 시스템적 관점에서 고찰하였고 이를 통하여 국가 R&D성과평가와 예산 정보가 연계 가능하도록 개선 프로세스를 제안하고자 하였다.

The private college education plays a crucial role both in training and supplying manpower needed for national economic growth and in increasing employability and personal labor earnings of individual workers. In oder for private college education to effectively respond to the rapid changes in industrial and occupational structures, it is necessary to secure appropriate level of investment funds and manage them efficiently. For this, it is required to discuss the structure, magnitude and management mechanism of the current private college education finance, changes in future demand for private college education and resultant changes in budget estimates, and new financial resources and allocation schemes. This study attempted to analyze current status and problems of private college education finance in Korea and, based on this analysis, to suggest future policy directions to improve private college education finance system. In order to make the private college education system in Korea competent and competitive enough to survive in international market, it is prerequisite to provide enough budget for the private college education and to manage the private college education finance in more efficient ways. First, for securing the adequacy and stability of investment budget for the private college education, it is recommended to 1) increase the government budget and put emphasis on the private college education; 2) diversify financial resources and induce financial contribution from private sector such as school juridical persons and enterprises. Second, for higher efficiency of financial management, it is recommended 1) make valid allocation standards and mechanism; 2) introduce competition system; 3) develop and utilize evaluation mechanism for the private college education finance to check adequacy, efficiency, accountability, and effectiveness; 4) apply consumer-oriented financial management scheme. In addition to the above policy measures, it is necessary to 1) make scientific forecasts of industrial and occupational structures periodically and apply these analyses to medium & long-term the private college education planning; and 2) redesign budget accounting system and develop the private college education performance indicators for the evaluation of accountability of the private college education institutions and administration institutes.

The expansion of upland crop cultivation in rice paddy fields is recommended by the Korean government to solve the problem of falling rice price and reduction of rice farmer's income due to oversupply of rice. However, water use efficiency is significantly influenced by the land use change from paddy field to upland. Therefore, this study aimed to evaluate the water budget of soybean grown in using APEX (Agricultural Policy and Environmental eXtender) model. The amount of runoff was measured in a test bed located in Iksan, Jeollabu-do and used to calibrate and validate the simulated runoff by APEX model. From 2019 to 2020, the water budget of soybean grown in uplands were estimated and compared with the one grown in paddy fields. The calibration result of AP EX model for runoff showed that R² (Coefficient of determination) and NSE (Nash-Sutcliffe efficiency) were 0.90 and 0.89, respectively. In addition, the validated results of R² and NSE were 0.81 and 0.62, respectively. The comparative study of each component in water budget showed that the amounts of evapotranspiration and percolation estimated by APEX model were 549.1 mm and 375.8mm, respectively. The direct runoff amount from upland was 390.1 mm, which was less than that from paddy fields. The average amount of irrigation water was 28.7 mm, which was very small compared to the one from paddy fields.

소방수요가 증가하고 형태가 다양화되고 있으므로 가장 필요한 것은 소방력을 충분히 보유하기 위하여 소방예산을 확보하는 일이다. 이러한 예산배정은 주민이 원하는 소방서비스를 충분히 제공하게 되어 사회적 후생만족에 기여할 것이다. 만약 소방예산이 소방수요, 소방력에 적합하지 않게 책정된다면, 소방관의 안전은 위협받게 될 것이다. 또한 위급한 재난이 발생하면 지방정부가 재난을 효과적으로 대처할 수 없을 것이다. 실제로 일부 시 군에서는 소방장비의 부족으로 많은 인명과 재산이 피해를 입고 있다. 본 연구의 목적은 소방예산이 소방력에 어떠한 영향을 주는지 알아보는데 있다. 이를 위하여 본 연구에서는 소방력, 소방예산에 대한 조사를 실시하였다. 그 다음, 이론적 배경과 과거연구를 근거로 3가지 가설을 설정하였다. 가설을 검증하기 위한 통계적 방법은 회귀방정식이다. 본 연구 결과, 주민 1인당 소방예산은 소방력에 양(+)의 유의적인 영향을 미쳤으나, 소방예산비율은 소방력에 유의적인 영향을 주지 않았다. 또한 공동시설세는 소방력에 음(-)의 유의적인 영향을 미치는 것으로 나타나, 공동시설세가 목적세로서의 역할을 하지 못하고 있음을 알 수 있었다.
