Service Function Chaining (SFC) supports services through linking an ordered list of functions. There may be multiple instances of the same function, which provides a challenge to select available instances for all the functions in an SFC and generate a specific Service Function Path (SFP). Aiming to solve the problem of SFP selection, we propose an architecture consisting of distributed SFP algorithm and central control mechanism. Nodes generate distributed routings based on the first function and destination node in each service request. Controller supervises all of the distributed routing tables and modifies paths as required. The architecture is scalable, robust and quickly reacts to failures because of distributed routings. Besides, it enables centralized and direct control of the forwarding behavior with the help of central control mechanism. Simulation results show that distributed routing tables can generate efficient SFP and the average cost is acceptable. Compared with other algorithms, our design has a good performance on average cost of paths and load balancing, and the response delay to service requests is much lower.

The metallic contact system of silicon solar cell must have several properties, such as low contact resistance, easy application and good adhesion. Ni is shown to be a suitable barrier to Cu diffusion as well as desirable contact metal to silicon. Nickel monosilicide(NiSi) has been suggested as a suitable silicide due to its lower resistivity, lower sintering temperature and lower layer stress than $TiSi_2$. Copper and Silver can be plated by electro & light-induced plating method. Light-induced plating makes use the photovoltaic effect of solar cell to deposit the metal on the front contact. The cell is immersed into the electrolytic plating bath and irradiated at the front side by light source, which leads to a current density in the front side grid. Electroless plated Ni/ Electro&light-induced plated Cu/ Light-induced plated Ag contact solar cells result in an energy conversion efficiency of 16.446 % on $0.2\sim0.6\;{\Omega}{\cdot}cm$, $20\;\times\;20\;mm^2$, CZ(Czochralski) wafer.

This study investigated the physicochemical and sensory characteristics of fish paste containing red snow crab Chionoecetes japonicus leg-meat powder (RMP) in 0, 3, 6, 9, and 12% concentrations. The moisture contents of fish paste with RMP ranged from 56.7 to 60.2% and the pH ranged from 7.0 to 7.7. The L values decreased as the RMP concentration increased, and a and b increased. The folding test for all of the fish paste samples scored AA, which indicates good flexibility. The hardness, springiness, gumminess, and cohesiveness increased with the RMP concentration. In the sensory evaluation, the fish paste prepared with 6% RMP was the most preferred. These results suggest that RMP can be added to fish paste to achieve high quality.

Methodology and application of Strategic Environmental Assessment (SEA) for policies, plans, and programs are still new approach in Vietnam. With a support from Vietnam-Swedish Project (SEMLA) and Ministry of Natural Resources and Environment (MONRE), SEA for the Tonkin Gulf Coastal Economic Belt Development Plan was conducted in 2008. Lessons obtained from this SEA may contribute to improving methods and practicing SEAs for regional development. The main lessons summarized in this paper are: (i) close cooperation between the planning and environmental teams from the beginning phase of a master plan; (ii) SEA should focus not only on impacts to the natural environment but also on main issues of socio-economic aspects; (iii) approaches and methods used in SEA should be appropriate to properly predict the impacts at regional-levels and cumulative impacts; (iv) a good SEA study may be achieved when detailed data on the environment and socio-economy of the study area are available and have active engagement of stakeholders, including project affected sectors, ecologists, planners, policy makers, etc. This paper is useful for whom, those work in SEA in regional development.

Currently, many organizations introduce ERP system as a key enabler of business strategic accomplishment and it can improve productivity and efficiency of organizations by integration and managing enterprise resources. Already many organizations have introduced ERP systems and the number of introduced ERP system is increasing steadily. Unfortunately, even though organizations have invested much money, previous studies showed the ERP systems had not always turned in good result. It is easy to find many studies that suggest that successful implementing strategies for ERP systems. This study reviewed the previous literature on strategic use of change management in enterprise. In order to establish a successful implementation of ERP, this paper suggests proper solutions to conduct change management according to implementation phase with activity and output, especially analyzing successful organizations in implementing ERP system through consistent change management.

Soft magnetic composite (SMC) material has recently received a significant attention in the area of high-speed machines because of its unique properties such as good design flexibility and low eddy current loss. However, SMC's electromagnetic property is poor compared to silicon steel in terms of saturation, relative permeability, and hysteresis loss. This paper presents a technique for utilization of SMC in two strategic designs of a switched reluctance machine (SRM) depending on a loss pattern. To investigate the effect of SMC's merits and demerits, the stator material is changed from laminated steel to SMC.

경영성과에 영향을 주는 경영환경은 플랜트의 호황에 의한 해외 수주 증가와 국내 주택시장의 침체 등 전략사업부(SBU: strategic business unit)별 명암이 뚜렷하다. 이러한 환경변화는 경영성과 측정 시 전략사업부의 전략적 중요도를 변화시킨다. 그러나 대형건설기업의 경영성과는 전략사업부별 경영성과를 BSC(Balanced Score Card)를 적용하여 일괄 합산하기 때문에 이러한 전략적 중요도의 반영이 어렵다. 이러한 방식은 환경변화를 반영하지 못한 왜곡된 경영성과를 도출할 수 있기 때문에 개선이 필요하다. 그러나 환경변화를 반영한 전략사업부별 비중에 대한 연구가 전무한 실정이다. 따라서 본 연구는 대형건설기업의 전사적 경영성과 측정을 위한 전략사업본부 비중분석을 목적으로 한다. 또한 전략사업본부 비중분석 모델을 제시하여 끊임없는 환경변화에 대응하여 비중을 수정 적용하는 방법을 제시하였다. 비중 분석을 위해 23명의 경영전문가와 실무자에게 설문을 실시하였으며 FD-AHP기법을 적용하여 결과를 정량화하였다. 본 연구의 결과는 전사적 경영성과 측정 시 전략적 왜곡을 최소화하며 환경변화를 반영한 분야별 비중산출을 위한 모델이 될 수 있을 것으로 기대한다.

Oil palm fronds (OPF) are one of the main by-products of the oil palm industry in Malaysia. It contains about 38.5 % crude fibre with ME values of about 5.65 MJ/kg dry matter. OPF has great potential to be utilized as a roughage source or as a component in a complete feed for ruminant animals. This paper briefly reviews the availability of OPF in Malaysia and its importance in the local beef and dairy industry. About 26 million metric tonnes of OPF are produced on dry matter basis annually during pruning and replanting operations in the plantations. The nutritive value of OPF and studies to improve its feeding value is highlighted. The optimum level of inclusion for ruminant feeding is 30 % and improvement to intake and digestibility can be further enhanced with addition of other oil-palm by-products. Performances of beef and dairy cattle fed fresh OPF or as silage, pellets and cubes are shown. Good quality OPF silage can be produced without using any additive and the significant improvement on the rate of growth and milk yield were shown. With good formulations, OPF based diets can allow live weight gains of between 600-850 g/day and for local crossbred dairy animals, milk yield of about 11.1 to 20.3 liter/day can be obtained. Pellet based on ground OPF seemed to be less well utilized for ruminant feeding due to its smaller particle size. OPF based cubes which have longer particle size is more suitable for beef and dairy cattle. Long-term feeding of OPF based feeds have been shown to produce good quality carcasses, and the meat is safe for consumption.
