This paper describes the procedure of recognizing the On-line Korean characters which are written on a graphic tablet. The effective recognition of primitives is performed by the use of stroke unit proceeding instead of coordinate unit under the base of definition of characteristic points which are fit to Korean character through the application of the characteristics of korean characters & input data on graphic tablet.

본 연구는 디자인 실무와 교육에서 전개되는 아이디어 스케치 과정을 인지적 그래픽 사고(Graphic Thinking)의 과정으로 보고, 인지적 사고 과정에서 시각적 디자인 사고의 과정의 고찰과 함께 이에 투입되는 언어/시각 정보의 영향을 실험/분석하였다. 실험방법으로 디자인 프로젝트를 설정하여 이의 프로토콜 분석을 시행하였으며, 그 결과를 SAS 통계시스템의 T-Test 분석을 하였다. 연구결과로서, 첫째로, 그래픽 사고는 추상적 /구체적 영역과 개념적/ 지각적 영역 사이에서 언어/ 시각 정보의 인지적 사고과정에 의해 진행되는 것으로 설명될 수 있으며, 둘째로, LCD 태블릿은 펜과 종이를 대체할 수 있는 적절한 장치임을 확인하였다. 셋째로, 컨셉 디자인 단계에서는 언어/ 시각 디자인 정보의 유형에 따른 영향에서 유의적인 차이가 있음을 확인하지 못하였다. 즉, 그래픽 사고과정에서 그래픽 이미지, 지각이미지, 그리고 정신 이미지가 복합적으로 작용되고 있음을 확인해주는 결과로 볼 수 있다. 금후 실험을 다각화하여 연구를 보완할 경우, 디자인 사고의 시각화 과정에 대한 보다 일반화된 이론 체계가 세워질 것이다.

Digital leader caught seat by modern's everyday life tool now by popularization of smart device such as Smart phone and Tablet PC. Therefore, desire of readers about electronic book practical use is increasing based on convenience and economic performance of electronic book. 1971, Michael S. Hart established Project Gutenberg to produced first electronic book because inputs American Independence Declaration Statement by computer and produce more electronic books. After that, an electronic book technology repeats several times development and American electronic book take is increasing rapidly. Sales volume of electronic books is dramatically increasing in Korea since digital device such as Smart phone and Tablet PC became popular. This research attempts to analyze factors influencing on shifting from paper book to electronic book. Results of this research proposed grounds for building business strategy. Finding is the factor of social influence is only significant to acceptability intention. It means user of e-Book enhance their acceptability intention along social phenomena.

Schedule management of construction work is critical to completing construction projects within a given period of time. Many efforts have been made and multiple tools have been developed to support the management of construction projects using smart devices such as smartphones and tablet PCs. This study proposed a method for managing construction schedules via a smart device using Flash. The interactive and graphic properties of Flash enable the development of an app that can allow a field manager to manage schedules easily and efficiently. A prototype was implemented using Adobe Flex Builder, and a sample network was applied in a smartphone. It is convenient for a construction manager to manage construction schedules using the tool because Flash controls graphic components easily. In further studies, network diagrams such as CPM (Critical Path Method) should be developed and applied to the app.

Printing technology is accepted by appropriate technology that smart phones, tablet PC, display(LCD, OLED, etc.) precision recently in the electronics industry, the market grows, this process in the ongoing efforts to improve competitiveness through the development of innovative technologies. So printed electronics appeared by new concept. This technology development is applied on electronic components and circuits for the simplification of the production process and reduce processing costs. Low-temperature process making possible for widening, slimmer, lighter, and more flexible, plastic substrates, such as(flexible) easily by forming a thin film on a substrate has been studied. In the past, the formation of the electrode used a screen printing method. But the screen printing method is formation of fine patterns, high-speed printing, mass production is difficult. The roll-to-roll printing method as an alternative to screen printing to produce electronic devices by printing techniques that were used traditionally in the latest technology and processing techniques applied to precision control are very economical to implement fine-line printing equipment has been evaluated as. In order to function as electronic devices, especially the dozens of existing micro-level of non-dot print fine line printing is required, the line should not break at all, because according to the specifications required to fit the ink transfer conditions should be established. In this study of roll-to-roll printing conductive paste suitable for gravure offset printing by developing Ag paste for forming fine patterns to study the basic physical properties with the aim of this study were to.

Recently, general purpose graphic processing units(GPUs) are being widely used in mobile embedded systems such as smart phone and tablet PCs. Because of architectural limitations of mobile GPGPUs, only a single program is allowed to occupy a GPU at a time in a non-preemptive way. As a result, it is difficult to meet performance requirements of applications such as frame rate or response time if applications running on a GPU are not scheduled properly. To tackle this difficulty, we propose to specify applications using synchronous data flow model of computation such that applications are formed with edges and nodes. Then nodes of applications are scheduled onto a GPU unlike conventional scheduling an application as a whole. This approach allows applications to share a GPU at a finer granularity, node (or task)-level, providing several benefits such as eliminating need for manually partitioning applications and better GPU utilization. Furthermore, any scheduling policy can be applied in response to the characteristics of applications.

최적 운항자세 선정 기술이란 주어진 운항 배수량과 운항 선속에서 최소의 저항을 가지는 즉, 최적의 연료 소비 효율을 가지는 초기 선수흘수와 선미흘수를 제시하는 것이다. 본 논문의 주 목적은 대상선박의 유효동력 데이터를 기반으로 주어진 운항조건에서 최대의 에너지효율을 가지는 최적의 운항자세를 선정하는 프로그램 개발하는 것이다. 본 프로그램은 인공지능 기법에 의한 파이썬 기반 GUI(Graphical User Interface)로 작성되어 선주가 쉽게 사용할 수 있도록 하였다. 그 과정에 있어 대상 선박 소개, 전산유체역학(CFD)을 통한 유효동력 데이터 수집, 심층학습을 사용한 유효동력 모델 학습 방법 그리고 심층신경망(DNN) 모델을 응용한 최적 운항자세 제시 프로그램을 구체적으로 설명하였다. 선박은 운항 별로 화물을 싣고 내리게 되고, 이에 화물 적재량이 변화되고 배수량이 변경된다. 선주는 배수량 별 예상 선속에 따라 최소저항을 가지는 즉, 최대의 에너지효율을 가지는 최적의 운항자세를 알고자 한다. 개발된 GUI는 해당선박의 태블릿 PC와 앱에 설치하여 최적 운항자세 선정에 활용 가능하다.
