Design reflects the time and cultural trends and thus can have different symbolic significance and functions depending on the perspective. While this is evident, corporations still insist that designers achieve viewers' complete understanding and satisfaction in their designs. Also, they refuse to accept the designers' interpretation on the grounds that they are subjective and incomplete interpretations even when in fact they are of superior intellectual standard. This problem is also found among the designers dealing with the clients. Thus, as long as all they are willing to accept is the fallibility of each other, the clash between designers and users is inevitable. To solve these problems, we need to have more objective and logical framework for achieving collective understanding on the interpretation of designs and symbols from the very stage of their development. The graphic design is a tangible product that represents the cultural phenomenon and needs to be interpreted as visual symbols. This makes the graphic design a semiological subject. Thus, a semiological approach will enable more analytical interpretations of polysemy of visual symbols. In this light, this study seeks to apply a semiological approach to suggest criteria for interpreting graphic designs as symbols. The criteria will serve as a useful tool for rational evaluation as well as strategic design development.

The emergence of new types of embedded computing devices and developments in wireless networking are broadening the domain of computing from the work place and home office to other facets of everyday life. This trend is expected to lead to a proliferation of Internet of Things (IoT) environments, in which inexpensive and interconnected computing devices are capable of supporting users in a range of tasks. Context-aware computing is a key source to develop such smart services. However, there are many challenges to enable services to be smart; Heterogeneous Computing Environments, Resource Limitations, Large Amount of Data Produced, and Different Requirements for Context Interpretation. Because of these challenges, there are difficulties in providing smart service by utilizing IoT devices. Currently, many researchers are conducting researches on mobile-computing based smart service development and provisioning and network infrastructure for interconnected IoT devices. Still, there are some limitations on developing core technologies for IoT computing based smart service development. In order to remedy this situation, this thesis presents a reusable framework that provides unique and noble features which are required in developing advanced context-aware IoT applications.

This study analyzes the effects of group characteristics of smart work users on intention for smart work activation(i.e., time flexibility, space flexibility, resource flexibility and ICT infrastructure). Also, this study analyzes the effects of different types of smart work depending on occupational groups, firm size and gender in local manufacturing companies. The results show that ICT infrastructure had the most significance in the early stage of smart work. On the contrary to the previous studies which focused more on time flexibility and space flexibility, this study exemplified that the resource flexibility demonstrated relatively higher significance than time flexibility and space flexibility. The results suggest the possibility of successful smart work by recognizing the change in organizational culture, specifically in face to face evaluation and vertical organizational culture to performance-based and horizontal organizational culture.

최근 들어 사회문제 해결형 과학기술혁신 활동이 활성화되고 있다. 과학기술정보통신부에서 추진하는 국민생활연구사업, 그리고 혁신본부에서 기획하고 있는 사회문제 해결을 위한 다부처 공동 기획사업 등이 추진되고 있다. 사회문제 해결형 과학기술혁신은 사회문제 해결을 최우선 목표로 삼고 있기 때문에 수월한 과학기술지식의 창출, 산업경쟁력 강화를 위한 혁신과는 목표와 추진체제가 다르다. 사회문제 해결형 과학기술혁신은 사회혁신과 과학기술을 결합하는 활동이라고 할 수 있다. 이렇게 새로운 유형의 혁신활동이 등장하면서 이를 바라보는 다양한 관점이 존재하고 있다. 본 발표에서는 각 논의들을 정리하고 향후 사회문제 해결형 과학기술혁신의 발전방향을 제시한다. 여기서는 크게 3가지 분류로 사회문제 해결형 혁신을 보는 관점을 정리한다. 첫 번째는 전문가 중심의 관점(Innovation for people)이다. 이는 전문가가 분석과 논의를 통해 사회문제를 정의하고 그 대안을 제시하는 접근이다. 많은 과학기술전문가들이 가지고 있는 틀로서 선형모델에 입각한 논의이다. 때문에 혁신의 선형모델이 가지고 있는 문제점, 피드백의 부족, 현장에 대한 이해 부족 등과 같은 단점이 있다. 두 번째는 시민사회 중심의 관점(Innovation by people)이다. 이는 현장의 문제 상황에 있는 시민들이 문제를 정의하고 혁신활동을 주도해야 한다는 관점이다. 이 관점은 일반 시민을 과학기술혁신의 주체로 호명하고 실질적인 문제 해결에 참여시키면서 주류 과학기술의 미흡한 현장 지역 지향성을 비판하고 있다. 그러나 혁신의 논의가 지역에 한정되면서 규모 확대의 어려움을 겪는 경우가 많다. 장기 지속성을 확보하는 데에도 난점이 있다. 세 번째는 전문가와 시민의 협업 관점(Innovation with people)이다. 이는 시민성과 전문성의 결합을 통해 민주주의를 고양하고, 현장 지식과 전문 지식의 융합을 지향하는 접근이다. 또 리빙랩과 같은 추진 체제를 적극적으로 활용한다. 그러나 전문가와 시민사회의 협업을 지원하는 인프라와 지원체제가 부족하면 여러 문제점이 발생할 수 있다. 본 연구에서는 이런 관점들의 한계를 극복하기 위해서 국지적 문제해결과 국가적 문제 해결의 연계, 실험의 중요성 강조, 전문가와 최종 사용자 및 시민의 실질적 협업을 위한 기반 구축, 시스템 전환 프레임의 도입을 정책 방향으로 제시했다.

The way people read news is changing, from print to screen. In this study, we aimed to understand the impact of the use of infographics in news on readers. According to a study conducted by Reuters Research Institute at the University of Oxford in 2017, the proportion of online consumers of news is steadily increasing, with over 51 per cent of Americans receiving news via social media. Additionally, newspaper subscription rates are rapidly declining. According to previous studies, the understanding of text information is higher in print media than on screen. Therefore, to compensate for the weaknesses in the understanding of online news, online news media are providing infographic news services to deliver good news. Therefore, this study attempted to understand the impact of using infographics in the news. To this end, three experiments were conducted. The findings from the study indicate that the use of infographics in news has a positive effect on users in terms of the variables measured, including cognitive effect and acceptance of news. As compared with print news, on-screen news was not as effective in terms of comprehension. However, we propose interactive infographics to enhance communication effect along with improved design.

How do we create a next generation Records Management System? Under a rapidly changing system development environment, the records management system of public institutions has remained stable for the past 10 years. For this reason, it seems to be the key cause of the structural problem of the Records Management System, which makes it difficult to accommodate user requirements and apply a new recording technology. The purpose of this study is to present a redesigned model for a next-generation records management system by analyzing the status of the electronic records management. This study analyzed "A Study on the Redesign of the Next-Generation Electronic Records Management Process," records management technology of advanced records management system, and a case of an overseas system. Based on the analysis results, the improvement direction of the records management system was analyzed from several aspects: functional, software design, and software distribution. This study thus suggests that the creation of a microservice architecture-based (MSA) and an open source software-oriented (OSS) records management system should be the focus of next-generation record management.

Landsat satellite images were analyzed to study vegetation change patterns of warm-temperate forests from 1991 to 2002 in Wando. For this purpose, Landsat TM satellite image of 1991 and Landsat ETM image of 2002 were used for vegetation classification using ENVI image processing software. Four different forest types were set as a classification criteria; evergreen broadleaf, evergreen conifer, deciduous broadleaf, and others. Unsupervised classification method was applied to classily forest types. Although it was impossible to draw exact forest types in rocky areas because of differences in data detection time and rough resolution of image, 2002 data revealed that total 2,027ha of evergreen broadleaf forests were growing in Wando. Evergreen broadleaves and evergreen conifers increased in total areas compared to 11 years ago, but there was sharp decrease in deciduous broadleaves. GIS-based management system for warm-temperate forest was done using Arc/Info. Geographic and attribute database of Wando such as vegetation, soils, topography, land owners were built with Arc/Info and ArcView. Graphic user interface which manages and queries necessary data was developed using Avenue.

Real-time remote monitoring system has an important value in many surveillance situations. It allows someone to be informed of what is happening in his monitoring locations. Kinect v2 is a new kind of camera which gives computers eyes and can generate different data such as color and depth images, audio input and skeletal data. In this paper, using Kinect v2 sensor with its depth image, we present a monitoring system in a space covered by Kinect. Therefore, based on space covered by Kinect camera, we define a target area to monitor using depth range by setting minimum and maximum distances. With computer vision library (Emgu CV), if there is an object tracked in the target space, kinect camera captures the whole image color and sends it in database and user gets at the same time a notification on his mobile device wherever he is with internet access.
