Since the North port in Busan started to operate in general pier (1, 2, central, 3 and 4), the business area had been expanded to Jasungdae, Shinsundae, Gamman zone and so on. However, these zones adjoin the Busan city and have caused problems to both logistics and city activities. The operation of Off-Dock Container Yard (ODCY) is a good representative example due to the limited sphere of Container Yard in this city. It increases logistics costs and causes serious social problems as a result of increasing traffic in the truck roads such as Uam and Chungjang roads. This paper aims to analyze the effects of the reduction in traffic of trunk roads in Chungjan, Uam roads and so on, when General Pier and Jasungdae Pier are Re-developed. The effects of the reduction in social cost from traffic congestion are also analyzed. Finally, we predict and evaluate the effects according to the re-development of two piers, north pier and Jasungdae pier.

Korean army currently considers the development of the new generation MLRS(Multiple Launcher Rocket System) as a new alternative, which responses on the renovation of the artillery and future battlefield environment. This study suggests that it presents cost-effectiveness of MLRS based on the Analytic Hierarchy Process and Parametric Estimating(PRICE H). According to this study, the cost-effectiveness of new generation MLRS presented that alternative A is 2.30 times and alternative B is 1.70 times, which are better than currently operating M270A1. Therefore, The best acquisition is alternative A that launcher is carried on currently operating 10ton standard truck but final acquisition alternative should be politically decided to consider viability of operator, performance and the latest of equipment.

배출권거래제도의 비용절감효과를 분석함에 있어 요소간 대체가능성 등 외부환경 변화에 대한 기업의 적응도를 반영하지 않은 공학적 추정치는 그 신뢰성에 한계가 있다. 또한 경제학적 분석방식을 시도한 연구의 대부분이 외부거래만을 대상으로 해온 반면에 거래실적의 다수를 차지하고 있는 내부거래에 대한 연구는 미미한 실정이다. 본 연구에서는 Gollop and Roberts (1985)의 경제학적 추정모형을 이용하여 미국 석탄발전소를 대상으로 $SO_2$ 배출권에 대한 내부거래의 비용절감정도를 측정한 후 효과의 크기 변에서 외부거래와의 차이를 규명하고자 한다.

At the 8th Party Congress in 2021, North Korea announced a plan to build 50,000 housing units in Pyongyang, and this paper analyzes the economic effects and related informal costs of of the project. Currently, Pyongyang is experiencing a significant housing shortage. It is estimated that the number of households in Pyongyang increased by 184,000 between 1994 and 2020, while the estimated new housing supply during the period was only 30,000. Pyongyang's 50,000 housing units construction project is characterized by the goal of improving the living conditions of workers, the application of the new city construction method, and the largest state-led housing construction since the Arduous March. The project is expected to generate economic effects such as increasing workers' motivation to work, increasing tourism resources, and generating income from related industries. On the one hand, a significant portion of the construction cost of the 50,000-unit housing project in Pyongyang is passed on to companies and households in the form of informal cost such as quasi-taxes and manpower mobilization. In addition, there may be congestion in the power supply and sewerage facilities that occur when moving in. If these costs are not taken into account, the feasibility of a housing construction project may not be properly assessed, making it difficult to sustain it in the long term.

Investment in health through an array of public health policies will lead to improvement of health at all levels, and the improved health can reduce the socioeconomic costs incurred with diseases. And finally, with reduced healthcare costs associated with diseases and health problems, economy will be able to achieve economic growth and development. Using simultaneous equations model, this study aims to identify this possible channel from public health policies to economic growth. Specifically, the policy effect is investigated on a basis of main disease groups and aging groups. The public health policies are proved to reduce healthcare costs related with disease groups including respiratory, digestive, circulative, and infectious disease, and with all age groups except 20~39 group. And the reduced healthcare costs have shown to increase the real gross domestic products in those group above.

현대 사회에서는 의사 결정을 위해 다양한 도구가 사용되고 있다. 대규모로 진행되는 토의나 토론에서는 데이터를 분석하는데 많은 비용과 시간이 소모되고 있다. 회의록 요약시스템은 기존 문서처리방법을 자동화하여 인건비 절감과 처리시간을 단축하는 긍정적 효과를 기대하고 있다. 본 논문은 기존에 수작업으로 진행되었던 과정을 보다 효과적으로 운영할 수 있도록 회의록 요약시스템을 설계하고 구현한다. 대규모 토론이나 토의에서도 요약시스템 통해 대표의견을 제시받아 정확한 의사결정을 하여 시간절약과 비용절감 효과를 기대한다.

The cost/benefit analysis method is frequently used in the feasibility study of investments on geo-spatial information system. The cost/benefit analysis method has been applied extensively in the feasibility study of conventional information systems and recently efforts has been made to apply this method to geo-spatial information systems as well. This study efforts were made to present a cost/benefit model suitable for Korean GSIS and this model was then applied to Facility Management. In establishment of the cost model, the items of various costs were defined and a survey was made to find the average unit cost of each item. For the benefit model, the benefits of implementing a geo-spatial information system is classified into tangible and intangible benefits and only th tangible benefits were further classified. The established cost/benefit model was then applied to a gas distribution company with more than 100 employees and more than 300,000 customers. A GSIS was designed and the cost its implementation was compared to the present manual method of operation.

The Organizations working with technological projects will be more and more common to connect consultants. Those who shall carry out the pre-analysis of the projects ought to have a professional knowledge to the area about economical methods with information technology and changed technology of surveying and mapping. New surveying and mapping methods, such as TotalStation, GPS, orthophoto, digital map, and satellite remote sensing, have totally changed the old concept of surveying. Also the technology for the new mapping has greatly changed from analog to analytical to digital during the past 50 years. Now, the proper choice of surveying and mapping methods becomes a decision on cost and efficiency rather than the use of a particular technology. As an example, GPS equipment dose cost considerably more than traditional surveying equipment, but the advantages it provides make it very cost-effective. In this study, the cost and benefit factors of the surveying and mapping projects are evaluated independently and benefit/cost ratio(B/C ratio) is used in benefit-cost evaluation of the different surveying methods. The benefit-cost model of surveying and mapping methods will produce economical result in the whole projects.
