In the cloud service, system resource such as CPU, memory, I/O bandwidth are shared among multiple users. Particularly, in Linux containers environment, I/O bandwidth is distributed in proportion to the weight of each container through the BFQ I/O scheduler. However, since the I/O scheduler can only be applied to conventional block storage devices, it cannot be applied to Zoned Namespace(ZNS) SSD, a new storage interface that has been recently studied. To overcome this limitation, in this paper, we implemented a weighted proportional I/O bandwidth sharing scheme for ZNS SSDs in dm-zoned, which emulates conventional block storage using ZNS SSDs. Each user receives a different amount of budget, which is required to process the user's I/O requests based on the user's weight. If the budget is exhausted I/O requests cannot be processed and requests are queued until the budget replenished. Each budget refill period, the budget is replenished based on the user's weight. In the experiment, as a result, we can confirm that the I/O bandwidth can be distributed on their weight as we expected.

The Development of Cost Management is embossed efficiently to use the budget for the construction industry. The government is exploring every efforts and polices to control increasing the budget for the construction industry. However, despite of the government's efforts, researches are insufficient for a cost management of development. Also, the changed cost of construction by frequent plan change is caused of decline in quality etc during an accomplishing project. Therefore, in this study, analyzed about principal official phase of design phase to solve the problem. In order to define clearly the target cost concepts in the planning phase apply to the DTC(Design To Cost) concept and technique at the development of cost management process which will be able to manage the enterprise expense. It's process is expected with the fact that will be the possibility efficiently of fixing target cost in the planning phase by the construction client and designer.

The economic renovation in Vietnam has shown promising achievements. The process of reforming and equitizing state-owned enterprises, and reducing subsidies from the government have made significant progress since 1986. However, this policy has not received the adequate valuation from leaders. Big companies have not been equitized, and are still managed and subsidized by the government, resulted in budget losses. Corporations have been dominated by political interests. This has led to arguments for better and more feasible measures which could save national budget. Corruption in Vietnam mostly originates from state-owned enterprises, for the monopoly was given by government to those enterprises as foreign partners continue to compete under market-oriented mechanism and transparent supervision. Therefore, renovation of the business mechanism, as well as speeding up equitization and minimizing people's properties, have become crucial in the regional integration trend. This is entirely a vital factor in the renovation process. This study explores plans, as well as the merits of the renovation process in Vietnam, ultimately envisioning to overcome current consequences and motivate Vietnam's economy.

It is very important to assess accurately the terms which are included in the heat budget equation of soil surface because they are used in the UM and miso-scale circulation modeling as well as in the micrometeorological studies. Each terms in the heat budget equation change according to the soil moisture content. So, it is necessary to specify clearly the relations between soil moisture content and these terms. Special experiment with micrometeorological measurements was executed to study these relations at Environmental Research Center of Tsukuba University, Japan. The results are as follow: 1. The soil moisture contents of 1 cm and 4 cm depth are oscillated with one day Period in drying process and the amplitude of variation of 1 cm depth is greater than that of 4 cm. 2. Increase in soil moisture contents due to precipitation result in decrease of albedo with step function. 3. Sensible heat is in reverse proportion to the soil moisture content and latent heat is in direct proportion to it. Latent heat is more sensitive than sensible heat according to the soil moisture variation. Net long wave radiation have high correlation with soil moisture. 4. Comparing with the radiative term with the flux term in wetting process due to precipitation, the energy transfer of the aero and thermodynamic flux is greater than that of the radiative heat flux.

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.

Buildings that are more than 10 years old generally have considerable repair and replacement costs due to the rapid deterioration of their systems. For public buildings in particular, which have national and social significance, considerable effort is required not only to ensure a long life cycle and safety but also to minimize the overall public expense. Along with increasing repair and replacement requirements, however, there have been problems related to the establishment of an accurate facility management budget. To address these concerns, a repair and replacement cost management system was constructed. This system manages both invested maintenance and forecast costs to establish a reasonable repair and replacement planning process and budget. The effectiveness of the system was verified through a pilot test targeting one of public Corporation (K).
