일반적으로 6 시그마 적용사례는 제조분야 중심으로 연구 발표되는 경우가 많고, 판매나 마케팅 분야의 적용사례는 찾기 힘들실정이다. 본 논문에서는 S전자의 전문상가에서 판매되는 노트북의 판매비중을 높이기 위해 6 시그마를 적용하여 노트북의 판매비중을 높이기 위해 프로젝트를 진행하였다.

The present study investigated the effects of different seeding rates on growth characteristics and seed productivity of the "Kowinearly" cultivar of Italian ryegrass (Lolium multiflorum Lam.) in paddy fields. Sowing Kowinearly in paddy fields under growing rice at the rates of 20, 30, 40, and 50 kg/ha resulted in seed yields of 1.57, 1.92, 2.06, and 2.09 ton/ha, respectively. Seed yield of Kowinearly was the highest at a seeding rate of 50 kg/ha (p<0.05), at which the cultivar was able to survive in winter and the weed ratio was low. Under these conditions, most growth characteristics such as winter survival (85%), weed ratio (10%), stems per square meter (1,006) were superior than those sown at other seeding rates (p<0.05). In addition, it has been reported that the economic efficiency of the 50 kg/ha seeding rate was higher than that of the other seeding rates.

The research related to the mobility support in the Internet can he classified into two fields. One is Macro mobility and the other is Micro mobility In case of \lacro Mobility, the standard, RFC 2002 by IETF is getting focused. But for Micro mobility, a variety of strategies have been discussed. In this paper. we introduce the concept of an LA and propose the strategy that makes it possible for the LA to fully concern frequent local handoff without using the HA. Therefore we can limit the longest handoH delay to a certain degree regardless of the distance between the MN and the HA of the MN. For the registration cost and the packet drop probability due to the registration delay, we prove the performance enhancement of the existing Mobile IP in case that we apply the concept of the LA to existing Mobile IP.

30 kVA rotating-field type Super-Conducting Generator is built and tested with intensive FE(Finite Element) analysis. The generator is driven by VVVF inverter-fed induction motor. Open Circuit Characteristic(OCC) and Short Circuit Characteristic(SCC) are presented in this paper. Also, the test result under the light load(up to 3.6 kW) are given. From the design stage, 2-D FE analysis coupled with the external circuit has been performed. The external circuit includes the end winding resistance and reactance as well as two dampers. When compared with the test data, the FE analysis results show a very good agreement.

In this paper, the conceptual design and FE analysis results of salient pole type alternator under no load condition are described. The designed alternator's rating is 180kW, 3-phase, 4pole, 380/220V, 0.8pf, 60Hz. The conceptual design is described by the process of designing the armature, field, and obtaining some of equivalent circuit parameters. The comparison of FE analysis to the designed results of alternator's output voltage value shows a good agreement.

Support vector quantile regression(SVQR) is capable of providing a good description of the linear and nonlinear relationships among random variables. In this paper we propose a sparse SVQR to overcome a limitation of SVQR, nonsparsity. The asymmetric e-insensitive loss function is used to efficiently provide sparsity. The experimental results are presented to illustrate the performance of the proposed method by comparing it with nonsparse SVQR.

The BESS has a major advantages such as load leveling, quick response emergency power (spinning reserve), frequency and voltage control, improvement of reliability, and deferred generation and transmission capacity construction. However, the economic feasibility of these systems requires justification from the customer side of meter. In this paper, we proposed the economic evaluation model of BESS which is modified and complemented the SYSPLAN model[2]. In addition, we analyzed a economic evaluation from the economic measures such as payback period, overall benefit, ROI, and ROR.
