오늘날 비즈니스의 가장 중요한 요소 중의 하나는 타이밍이며, 이의 예측 정확성이나 대응력에 따라 비즈니스의 성패 정도가 달라질 수 있다. 이러한 의사결정력을 강화하기 위해서 많은 기업에서는 글로벌 선도시장의 흐름이나 선진기업의 성공전략에 대한 벤치마킹을 수행한다. 모바일 산업에 관한 한 한국은 글로벌 선도시장으로, 한국의 휴대폰 시장 변천을 분석하고 구매요인 및 요인간 관계를 규명하여 지표화할 수 있으면 여타 국가에서 시장주도 전략에 중요한 역할을 수행할 수 있을 것으로 예상된다. 따라서 테크놀로지 수용에 대한 기존 문헌연구를 바탕으로 끊임없이 변화하는 정보기술 제품이나 서비스의 수용 여부 및 시장 성장 예측에 대한 프레임워크를 개발 제시하는 것이 본 연구의 기본 목적이다. 개인차원의 기술 수용 모형인 Technology Acceptance Model(TAM) 및 여러 수정모형에서 규명된 다양한 변수들은 실증적인 연구의 결과로서 중요성은 갖으나, 여전히 연구 및 실무 관점에서는 특정 상황에 대한 통계 분석 결과의 제시라는 점에서 한계를 갖는다. 비교 대상국으로 선택한 중국은 그 국토만큼, 인구만큼, 문화만큼 다양하고 복합적인 시장이며, 동시에 누구나 공감하는 거대한 잠재시장이므로, 한국시장의 분석을 바탕으로 중국시장에 대한 향후 성장을 지표로 예측할 수 있다면 국내 기술 및 상품 수출의 기회를 보다 더 수익성있게 포착할 수 있을 것이라고 판단했기 때문이다. 그러나 여기서는 연구의 의의, 대표적인 일부 변수의 평가와 연구방법에 대한 제안에 국한하여 설명한다.

This paper presents two advanced hybrid pulse-width modulation (PWM) strategies for multilevel inverters (MLIs) that provide both common-mode voltage (CMV) elimination and current ripple reduction. The first PWM utilizes sequences that apply one switching state at the double ends of a half-carrier cycle. The second PWM combines the advantages of the former and an existing four-state PWM. Analyses of the harmonic characteristics of the two groups of switching sequences based on a general switching voltage model are carried out, and algorithms to optimize the current ripple are proposed. These methods are simple and can be implemented online for general n-level inverters. Using a three-level NPC inverter and a five-level CHB inverter, good performances in terms of the root mean square current ripple are obtained with the proposed PWM schemes as indicated through improved harmonic distortion factors when compared to existing schemes in almost the entire region of the modulation index. This also leads to a significant reduction in the current total harmonic distortion. Simulation and experimental results are provided to verify the effectiveness of the proposed PWM methods.

After the launch of smart phones, various miniaturized smart devices such as wearable and IOT devices have deeply embedded in human life, and have created a technology-oriented society. In this technology-oriented society, technology development itself is important, however it seems more important to utilize existing technology appropriately and deliver effectively to human life. As the computer became personalized after the appearance of PC, human-centered computing such as HCI and UCD had begun to appear. However, most of the researches focused on technology that made human being convenient to interact with computer such as computer systems design and UX development. In the technology-oriented society, it seems more urgent to apply existing technology to human life. In this paper, we propose a methodology, 'Digital Leveraging' which guides how to effectively apply technology to human life. Digital Leveraging is the way of convergence between technology and humanities.
