윤세환(Se-Hwan Yoon),류광수(Kwang-Su Ryu),양시훈(See-Hun Yang) 한국자기학회 2022 韓國磁氣學會誌 Vol.32 No.1

In this study, we experimentally observed the domain wall creep motions under the magnetic field in the ferromagnetic Co/Ni/Co magnetic wires with or without antiferromagnetic IrMn layer, respectively, using a magento-optical Kerr microscope system capable of real-time magnetic domain observation. As a result of the observation, it was found that the strength of the magnetic field required to move the magnetic domain wall was larger in the sample with the IrMn layer than the sample without the IrMn layer, and also, it was increased as the wire width decreased. In addition, we found that the magnetic domain wall speed characteristics according to the strength of the magnetic field in the two samples were well explained by the thermally activated model assuming the domain wall creep motion.

스마트 디바이스를 활용한 박물관 및 미술관 관람 경험 서비스 디자인

엄선영(Um, Seon Young),윤세환(Yoon, Se Hwan),김용세(Kim, Yong Se) 한국디지털디자인협의회 2015 디지털디자인학연구 Vol.15 No.2

본 논문은 타 문화 예술 분야 대비 관람률이 저조한 뮤지엄 서비스의 활성화를 위한 방안으로 기술과 문화 예술을 융합한 뉴미디어 기반의 모바일 서비스를 적용하여 경험재인 뮤지엄 서비스의 정보 탐색재화 가능성을 검토한 후 경험적 소비가 확대 재생산되는 서비스 구조를 디자인하는 것을 목적으로 하였다. 서비스 디자인 방법론을 적용하여 뮤지엄의 As-Is 상황인 문제점과 이해관계자의 요구사항을 분석해 핵심 목표 가치를 도출하고, 이를 개선하기 위한 방안으로 모바일 서비스를 제안하였다. 이어 모바일 서비스의 수용 의도를 분석하기 위해 이론적 학문 분야인 사회심리학의 기술수용모델과 혁신확산이론을 기반으로 연구 모형의 선택 요인과 가설을 설정하고 서비스 수용자 중심 현장설문 조사를 통해 각 영향 요인의 타당성을 분석한 후, 이를 서비스 개선 방향에 반영하고 고객 경험 샘플링 및 분석 방법을 이용해 연구모형의 타당성과 적합성을 검증하는 등 뮤지엄 서비스 전반에 대한 디자인 연구작업을 진행하였다. 최종적으로 제안된 To-Be 뮤지엄 서비스 개선 모델은 관람 본질을 추구하는 ‘행위"를 확대하는 디자인으로, 서비스 수용자인 관람객의 적극적 개입을 유도하는 행위추가를 통해 관람객의 문화 예술에 대한 통찰력(자의적 해석)을 끌어내고 이를 소속된 사회 관계망에 확장시켜 지속 가능하고 확장 가능한 형태의 뮤지엄 서비스를 디자인하는 것으로 하였다. This paper is intended to design a service structure where experience is expanded after reviewing the possibility that museum service, experience goods, becomes search goods by applying mobile service based on new media created through convergence of technology and culture & art as a measure to activate the service of museum which the percentage of visits to is low in comparison with other culture and art fields. With regard to the background of suggesting mobile service, service development model was established on the basis of technology acceptance model and innovation diffusion theory of social psychology, theoretical science field. That was modeled by using the service design methodology, empirical science field. And the validity of each influencing factor was analyzed through service user-centered field review survey, and then the appropriateness of service development model was verified through experience evaluation while prototype was seen. A finally suggested service development model was design that spread activity pursuing the essence of tour, and sustainable, extendible type of service design was suggested by extending visitors’ insight into culture and art to social network which they affiliated themselves with after extracting it through the addition of activity inducing visitors, service users, to actively intervene.

A lot of electrical energy is used in our daily life. While energy saving concerns are overall, consumption practices of people in general are very different. People want to control their energy use and by knowing the amount of energy they use. Smart plug is a new device that measures electricity usage through each plug at an outlet with on/off control. User experience for electrical devices in regards to electricity usage should be newly designed. In this study, based on the survey, personas have been devised and their energy use experience in relation with smart plugs have been designed. Service models have been designed aswell. By designing service with smart plug, user could enhance the experience of energy usage and saving and energy consumption practices could be improved in a sustainable manner.

관광지의 관광동기유형별 관광지 선호 속성의 차이에 관한 연구 -충청남도 관광지를 중심으로-

박진영 ( Jin Young Park ),윤세환 ( Se Hwan Yoon ),홍경옥 ( Kyung Ok Hong ) 대한관광경영학회 2010 觀光硏究 Vol.25 No.4

본 연구에서는 충청남도 주요 관광지를 방문한 관광객들을 대상으로 관광객들을 관광동기 유형별로 나누고 관광동기 유형별 관광동기 및 관광지 선택 속성의 차이에 대해서 실증적으로 검증하는데 목적을 두고 있다. 본 연구의 실증결과를 통해 몇 가지 중요한 사실을 발견할 수 있었다. 첫째, 6개의 모든 관광동기에서 군집별로 통계적으로 유의한 차이가 있는 것으로 나타났다. 추후 검증 결과 휴식동기, 자아실현동기, 자긍심동기, 유희성동기는 적극적 활동형일수록 높은 것으로 나타났고, 동반자동기는 소극적 활동형일수록 높은 것으로 나타났다. 그리고 일상탈출은 중립적 활동형일수록 높은 것으로 나타났다. 둘째, 활동/체험성요인, 친숙성요인, 자연/문화성 요인, 접근/비용성 요인의 4개요인 모두에서 관광지 선호속성에서 군집별로 통계적으로 유의한 차이가 있는 것으로 나타났다. 추후 검증 결과 4개의 관광지 선호 속성 모두에서 적극적 활동형일수록 높은 것으로 나타났고, 소극적 활동형일수록 낮은 것으로 나타났다. The primary aims of this study are two-fold: first, to identify the types of motivations which exist in the tourists visiting the destinations in Choongchung Nam-Do province; and second, to empirically verify the differences of the tourism destinations` preference attributes of the tourists. The findings, based on the quantitative analyses, exhibit that: six types of the motivations reveal significant differences by the clusters; and that all four preference attributes demonstrate the significant differences by the clusters.

Product-Service Systems (PSS) has drawn significant attention since it can effectively address diverse values of consumers by integrating products and services. PSS has been defined as a system of products, services, supporting networks and infrastructure that is designed to satisfy customer needs and to generate values. Manufacturing companies can accomplish business innovation by devising new service elements and providing PSSs starting from their products. Such new efforts are called manufacturing servitization. With analysis of the company’s business contexts, diverse strategies could be set for servitization. Services could be developed so that their product functions can be supported. On the other hand, new services could be devised to drive active emotional values of their customers in a broadly related manner with their products. In this way, different servitization strategies in service space could be employed. In this paper, the product-service integration spaces for comparison of product-service systems in manufacturing servitization is briefly sketched Various issue spaces, termed dimensions, would be used including service space, customer space, value space and business model space. Diverse PSS cases, including well-known PSSs and brand new PSSs, will be classified and compared to demonstrate the product-service integration spaces.
