본 연구는 디지털 정보격차 수준에 따라 소비자집단을 유형화하고 유형별 특성을 파악하는 것을 통해 실효적인 디지털 정보화 정책을 제안하는 것을 목적으로 한다. 이를 위해 인터넷 이용 경험이 있는 소비자를 대상으로 온라인 및 현장 설문조사를 통해 총 402부의 자료를 수집하고 SPSS 26.0 프로그램을 이용하여 자료를 분석하였다. 디지털 기기에의 접근, 역량, 활용수준을 기준으로 K-평균 군집분석을 실시한 결과 '기기애호형','능숙활용형', '일반형', '디지털소외형'의 4개 소비자집단이 유형화되었다. 소비자유형별로 디지털 정보격차의 선행변수인 인구통계적 특성, 사회적 자본, 미래정보사회에 대한 인식, 기술에 대한 혁신성, 불편감, 친밀감의 유의한 차이가 확인되었다. 또한, 소비자유형별로 디지털 정보격차의 결과변수인 디지털 기기활용 만족도와 기기이용의도의 유의한 차이가 나타났다. 본 연구는 디지털 정보격차 수준에 따른 소비자유형을 도출하고 소비자유형별로 맞춤화된 학술적, 실무적 정보격차 해소방안을 제안한다는 점에서 의의를 가진다.

Ultimately, this research will focus on the activity traits of future customers in the convergence age. To accomplish that, firstly, researcher develop measures for assessing the convergence level of digital devices and digital services. Next, this will investigate the behavioral traits of people who use specific devices or services on the internet or mobile networks. This study proposed five convergence measures each for devices and services. For digital devices, measures such as converged functions, accessibility to network, portability, immediate communicability, and expandibility of functions were utilized. For digital measures such as scope of users, newness, social network level, ease-of use on mobile networks, and expandibility of information were used. We believe that the research results can provide insights for those wishing to explore the convergence level of devices and services and those developing high-level converged devices and digital services.

정보통신기술의 융합으로 온 차세대 혁명인 4차산업혁명의 시대 속에 살고 있는 우리들의 일상은 하루에도 몇 번씩 가상과 실제 사이를 오가고 있다. 이러한 일상 속에서 정보의 저장방식은 가상적인 방식으로 대체되어 가고 있다. 이제 한 사람의 디지털 기기는 그 사람의 정체성을 나타내는 수단으로 작용할 수 있으며 이는 마치 서구 근세 시대 '분더캄머'의 공간이 가상적으로 변한 듯하다. 본 논문은 디지털 기기를 '디지털 분더캄머'의 시각으로 바라보고 '디지털 분더캄머'가 오늘날 현대인들의 일상 속 상호작용, 인지와 이해, 사고방식을 어떠한 방식으로 변화시켰는지에 대해 논의한다. 그리고 이를 진화하는 디지털 기술과 소통에 대해 작품활동을 펼쳐온 영국의 시각예술 작가인 마크 레키의 작품 시리즈 'Universal Addressability of Dumb Things'와 'UniAddDumThs'와 연결시켜 분석을 진행하였다. 작품 속에 반영되어 있는 오늘날의 디지털적 환경과 특성, 이의 시각적 표현성에 대해 논의하고 이를 현 시대의 '디지털 분더캄머'의 특성과 연결지어 분석해 보았다. 본 연구를 통해 우리들이 직면하고 있는 새로운 패러다임의 전환에 대해 인지하는 계기가 되기를 바라며 이러한 시대 속에서의 창의적 표현의 가능성 역시 확장되기를 바란다.

In this paper, we propose the miniaturization size of wearable Range of Motion(ROM) and a system that can be connected with smart devices in real-time to measure the joint movement range dynamically. Currently, the ROM of the joint is directly measured by a person using a goniometer. Conventional methods are different depending on the measurement method and location of the measurement person, which makes it difficult to measure consistently and may cause errors. Also, it is impossible to measure the ROM of joints in real-life situations. Therefore, the wearable sensor is attached to the joint to be measured to develop a miniaturize size ROM device that can measure the range of motion of the joint in real-time. The sensor measured the resistance value changed according to the movement of the joint using a load cell. Also, the sensed analog values were converted to digital values using an Analog to Digital Converter(ADC). The converted amount can be transmitted wireless to the smart device through the wearable sensor node. As a result, the developed device can be measured more consistently than the measurement using the goniometer, communication with IoT-based smart devices, and wearable enables dynamic observation. The developed wearable sensor node will be able to monitor the dynamic state of rehabilitation patients in real-time and improve the rapid change of treatment method and customized treatment.

The representative study of Patellofemoral Joint Merchant method can show the view for inspection of the sulcus angle, congruence angle and diagnose whether there are the vertical fractures and recognize the degree of dislocation and patella subluxation. However, anatomical correlation about the degree of knee joint curvature changes during position adjustment and distortion of the image reduces reproducibility. In order to resolve these problems, Merchant method needs to use assisting device which reduces the occurrence of repeat projection and effectively to increase unification of examination and the consistency of the image. However, there are disadvantages for patients who take other examinations. For example, they have to change the position for every examination and it might cause the patient's discomfort and increase of examination time. In this study, we newly devised commercial assisting device which improves the reproducibility of the images and reduces inconvenience of patients movement. Further research should be taken to obtain a image without patient's movement and to reduce the time of the examination than existing method.

Recently, as the heterogeneous network (HetNet) has been deployed widely to support various kinds of Radio Access Networks(RANs) with a combination of Macro, Pico, and/or Femto cells, research and standardization efforts have been very active regarding the concept of Licensed Shared Access (LSA) for supporting spectrum sharing. In order for a mobile device to efficiently support the spectrum sharing, the mobile device shall be reconfigurable, meaning that its radio application code has to be adaptively changed in accordance with the hopping of desired spectral band. Especially, Working Group 2 (WG2) of Technical Committee (TC) Reconfigurable Radio System (RRS) of European Telecommunications Standards Institute (ETSI) has been a main driving force for developing standard architecture for Multi-mode Mobile Device (MD) that can be applied to the LSA system. In this paper, we introduce the Multi-mode MD architecture for supporting LSA-based spectrum sharing. An implementation of a test-bed of Multi-mode MD is presented in order to verify the feasibility of the standard MD architecture for the purpose of LSA-based spectrum sharing through various experimental tests.
