  • VMP(Variable Message Protocol) 는 비트 단위의 가변형 메시지 처리 프로토콜로서 근실시간 상황 공유를 가능하게 하는 육군 전술 데이터링크 프로토콜이다. A 시스템은 현재 개발이 진행 중이며 개발이 완료되면 육군의 시스템으로 운용될 예정이다. A 시스템에는 VMP 처리 단말기가 탑재되고 VMP를 활용하여 A 시스템간 전술 정보 교환이 가능하다. A 시스템은 장착된 상황 정보획득 장치를 통해서 상황 정보를 획득할 수 있고 VMP를 활용하면 상황 정보 획득 장치로부터 획득한 정보를 타 A 시스템과 공유할 수 있다. 본 논문에서는 A 시스템에 장착된 상황 정보 획득장치로부터 획득한 정보를 VMP 단말기를 탑재한 A 시스템 간에 공유할 수 있게 하는 방안과 공유 속도의 최적화 방안에 대하여 연구하였다. 최적화 방안으로 일괄 전송 방식 적용, 첩보 보고과정의 생략, 여러 개의 상황 정보를 하나의 패킷으로 묶음 전송하는 방안을 연구하였다. 그리고 실험을 통하여 연구 방안이 적용된 VMP 단말기의 상황 정보 공유 시간이 기존 VMP 단말기에 비해 76.8% 단축되는 것을 확인하였다.

  • Defining value as a measure of how well the project value objectives are met, Value Management Process (VMP) is considered to be any management effort or process that can proactively pursue one or more project objectives (i.e., security/safety, cost effectiveness, schedule optimization, and risk containment). The collection of 44 VMPs has been established based on a rigorous effort conducted by Construction Industry Institute (CII). Because varying circumstances on each project determine the level of suitability, it is crucial to identify which VMP should be implemented on a particular project. The current VMP selection process is primarily based on human intuition. The main objective of this paper is to provide a systematic method to facilitate the usage of VMPs on a particular project. This paper identified and quantified the selection principles (i.e., targeted value objectives, timing of initiation, project characteristics, and relative impact). The data collected from industry practitioners and VMP experts characterized each VMP in terms of the magnitude of benefit. An automated selection tool by Visual Basic Application (VBA) on MS Excel TM, was developed and proved its validity. As a pioneering study, this paper provides a comprehensive and structured knowledge on the subject of VMPs. From the industry's perspective, the automated selection tool, the premier of this study, contributes the facilitation of the VMP implementations in the construction industry thereby maximizing the potential benefits to a particular project.

  • 현재 철제유물 강화처리 시 사용하는 아크릴계 수지인 Parabid NAD10은 용제로 VM&P Naphtha만을 사용하고 있다. 그러나 이를 사용하여 강화처리 할 경우 코팅 후의 광택이 높아 전시 및 관람에 불편함을 준다는 문제가 제기되고 있다. 이러한 단점 보완을 위해 대체 용제로 YK-VMP를 선정하여 각 용제별 코팅 특성을 비교 분석하였다. 표면관찰, 박막 두께, 접착력, 접촉각 및 표면에너지, 광택도, 황변실험, EIS 평가 등의 일련의 분석을 통해 용제별 코팅 특성을 비교한 결과, 기존의 VM&P Naphtha를 대신하여 YK-VMP를 사용하여도 강화처리 효과에는 큰 영향을 주지 않으면서도 광택을 더 낮춰주는 효과가 나타나는 것을 확인하였다.

  • This study is aimed at identifying the value of marginal products(VMP) of agricultural labor, capital and land. The resources are the major portion of input costs of agricultural projects. To appraise economic feasibility of agricultural projects, the real value of the resources would be estimated by VMP of the inputs rather than by distorted actual market prices such as rural wages, rent and interest. To convert the market wage rate into shadow wage rate, covertion factor of 0.90 would be appicable based on the study results. To evaluate the right of way and compensation, VMP of land is recommendable to apply in land pricing rather than actural land rent prevailing in rural area which has been underrated on account of labor shortage and difficulty of farming. Discount rate as a opportunity cost of capital should be applied 7-8% considering the VMP of capital and interest rate of foreign loan from IBRD and ADB. For the successful appraisal of the agricultural projects, the recommendation of this study would be applied in the future.

  • Background: Elderly patients with multiple myeloma (MM) are vulnerable to adverse events (AEs). This study evaluated adherence to chemotherapy and treatment outcomes in elderly patients treated with a frontline bortezomib (BTZ), melphalan, and prednisone (VMP) regimen and regimens without BTZ. Methods: One-hundred and forty elderly patients who were diagnosed with MM from March 2007 to March 2015 were included in this retrospective study. To evaluate regimen adherence, patients who were treated with more than 4 cycles were assigned to the good adherence group. Results: Among the 140 patients, 71 were treated with a frontline VMP and 69 with non-BTZ regimens. The median age was 71 years (range, 65-90 years). The VMP group showed a higher complete response rate than the non-BTZ group: 26.8% vs. 7.2%. More patients in the VMP group achieved ${\geq}$very good partial response (VGPR) and ${\geq}PR$. In the VMP group, 27 patients (38.0%) received less than 4 cycles. The VMP good adherence group showed a higher 3-year overall survival (OS) rate (70.9%) than the poor adherence group (60.2%, p=0.059). In the multivariate analysis, treatment with ${\geq}4$ cycles of VMP was a favorable factor for OS. Conclusion: A good adherence to a frontline VMP regimen resulted in favorable long-term survival. Adequate management of AEs will be needed to achieve favorable outcomes in elderly patients with MM.

  • Cloud providers now face the problem of estimating the amount of computing resources required to satisfy a future workload. In this paper, a virtual machine provisioning (VMP) mechanism is designed to adapt workload fluctuation. The arrival rate of forthcoming jobs is predicted for acquiring the proper service rate by adopting an exponential smoothing (ES) method. The proper service rate is estimated to guarantee the service level agreement (SLA) constraints by using a diffusion approximation statistical model. The VMP problem is formulated as a facility location problem. Furthermore, it is characterized as the maximization of submodular function subject to the matroid constraints. A greedy-based VMP algorithm is designed to obtain the optimal virtual machine provision pattern. Simulation results illustrate that the proposed mechanism could increase the average profit efficiently without incurring significant quality of service (QoS) violations.

  • The printed circuit board (PCB) can be used only 2 layers of front and back. Therefore, the wiring line segments are located in 2 layers without crossing each other. In this case, the line segment can be appear in both layers and this line segment is to resolve the crossing problem go through the via. The via minimization problem (VMP) has minimum number of via in layout design problem. The VMP is classified by NP-complete because of the polynomial time algorithm to solve the optimal solution has been unknown yet. This paper suggests polynomial time algorithm that can be solve the optimal solution of VMP. This algorithm transforms n-line segments into vertices, and p-crossing into edges of a graph. Then this graph is partitioned into 3-coloring sets of each vertex in each set independent each other. For 3-coloring sets $C_i$, (i=1,2,3), the $C_1$ is assigned to front F, $C_2$ is back B, and $C_3$ is B-F and connected with via. For the various experimental data, though this algorithm can be require O(np) polynomial time, we obtain the optimal solution for all of data.

  • 본 논문에서는 클라우드 자원의 무중단 수직 확장 서비스 제공을 위한 VMP(Virtual Machine Placement) 방안을 제시하였다. 수직확장을 위해서는 물리 서버의 여유 공간을 사전에 확보해야 하기 때문에, 이를 위한 FirstFit 배치 전략 기반의 가상 서버 할당율을 가변적으로 조정하는 "일반-혼합-수직의 모드 전환" 알고리즘을 제시하였으며, 수직 확장 비율, 가상화율, 여유자원율 등을 파라미터로 하여 시뮬레이션을 수행하였다. 시뮬레이션 결과, 수직 확장 비율이 50% 일 경우에 여유 공간을 고려하면 전체적으로 150%의 자원의 필요하나, 제안한 알고리즘의 시뮬레이션 결과로는 최대 125%의 여유 공간만을 필요로 하는 것으로 나타났다.

  • Project value can be increased by implementing the most suitable one or more Value Management Processes (VMP). For the past decades, a variety of innovative management processes have been increasingly introduced into the construction industry. Each VMP is considered to be significantly beneficial for capital facility projects to proactively achieve one or more project value objectives. This paper covers the compilation of the 44 VMPs and provides their leveraging project characteristics that require the implementation of one or more VMPs. The results of data collection establish relative importance between the VMPs and the project characteristic factors in collaboration with 51 experts from both industry and academia. In the lack of industry awareness of both VMPs and their causal factors, the results of this study can facilitate the implementation of the VMPs and ultimately enhance the value of a particular capital project.

  • Producing animal products from farm to table emits massive amounts of greenhouse gases (GHGs). Modified meal plans, mainly including vegetables and grains, have been recommended to reduce GHG emissions. However, these meal plans have not been developed with regard to the micronutrient content, but rather with regard to the energy requirements of grains and vegetables, which could result in a nutritional imbalance. For this reason, we investigated a common Korean suggested meal plan (SMP) from the National Institute of Agricultural Sciences, in which nutritional conditions were considered, and evaluated its GHG emissions using the Life Cycle Assessment Inventory Database and nutritional values. The SMP, which included meat, was based on the Korean Nutrition Society for adult men age 19 to 29, and was changed to a vegan meal plan (VMP). Animal-based protein sources were substituted for meat alternatives, such as beans and tofu, for which carbon footprint data was available. To compare the nutritional differences, the 9th Korean Food Composition Tables I and II were consulted. To calculate GHG emissions, the carbon footprint data of the food was converted to a CO2 equivalent (CO2e) using a procedure from the Foundation of Agriculture Technology Commercialization and Transfer. It was found that GHG emissions per calorie were 18% lower for the VMP when compared to the SMP. However, if GHG emissions per total amino acids were evaluated, the VMP GHG emissions per total amino acids were 0.12 g CO2e/mg, while the corresponding value for the SMP was 0.06 g CO2e/mg. The Korean daily meat intake reported by the Korea Agricultural Statistics Service was 37.1% lower than in the SMP, but when converted to a protein intake the figure was 17.0% lower. It was found that each SMP resulted in more GHG emissions than the VMP, but when considered as GHG emissions per total amino acids, the opposite pattern was apparent. There is a need to conduct more detailed studies of the variation in GHG emissions with different meal plans, using the daily meat intake per person.
