In this paper, PIG(Pipeline Investigation Gauge) system is introduced and off-line navigation method for the system is studied. Off-line navigation is obtained by using a smoothing filter and the position of the point with some problems in gas pipeline can be detected with a good accuracy in real pipeline investigation experiment.

In the existing robot programming methods, off-line method because important role of programming because of improvement of hardware and softeare of PC. The purpose of this study is to develop practical robot programming system for polishing task using PC. In the first place, we have investigated the existing robot programming systems, and derived the requirement of this programming system from the existing systems. And we have decied the structure of this system. After that, we have developed this system. Using Windows software, this programming system has man/machine interface function. Therefore users can use easily and quickly.

스마트 시대라고 불리는 현재, 사람들은 이제 오프라인 만남보다 온라인 만남이 편리하고 익숙하다. 하지만 온라인을 통한 만남은 가볍게 느끼는 경우가 많으며, 구성원들이 서로의 감정을 느끼기 어려워 교감이 잘 되지 않는다는 문제점이 있다. 본 논문에서는 이러한 문제를 해결하기 위해 오프라인 만남을 활성화 할 수 있는 모바일 애플리케이션 위콕을 제안한다. 사용자들의 위치정보와 선호도를 반영하여 약속 장소를 추천하는 애플리케이션인 위콕은 기능중심의 UI와 간단한 조작과정을 제공한다. 위콕은 클라이언트/서버 구조로 구현되었으며, 현재 동시에 3명의 사용자 간의 장소 추천을 지원한다. 위콕은 만남의 공간을 온라인에서 오프라인으로 확대시키는 접점이 되어 온라인, 오프라인 양방향으로의 교류를 가능하게 한다. 이제 사용자는 위콕을 통해 쉽고 편리하게 오프라인 만남장소를 정할 수 있다.

A "Showrooming" phenomenon has emerged due to the rapid growth of the on-line shopping market and is associated with consumer shopping patterns. This phenomenon is resulted in new strategies such as the Omni-Channel strategy that are now being employed by the off-line retail industry to meet the needs of consumers who seek information on-line. In particular, human services provided in department stores (which still occupy an important place in the off-line retail industry) are reaching limitations in the ability to maintain consumers. This study provides basic data for the Omni-Channel strategy of domestic department stores by researching and analyzing Omni-Channel strategy cases in Manhattan. This study dissects and analyzes the "Showrooming" phenomenon and the development of the Omni-Channel strategy through a literature review as well as analyzes the Omni-Channel success case of Macy's department store. The findings indicate that the use of the Omni-Channel strategy by Macy's department store has solved the problem of "Showrooming," by integrating on-line and off-line shopping to provide an efficient and convenient shopping experience for consumers. The Omni-Channel strategy offers a means for off-line stores to connect to the online shopping behavior of consumers. The results suggest the need for an organic combination of on-line and off-line distribution channels to adapt to changes in consumer shopping patterns due to a recession in the domestic market.

This study was implemented to offer materials for the activation of On-line food shopping mall though census about purchasing food. A percentage of people who had accessed to On-line food shopping mall was 53.8%, and who had an experience of purchasing food at the On-line sopping mali was 18.9%. The number of food purchasing in On-line food market is $1{\sim}3$ times(67.7%). It is general that an amount of food purchase is less than 100,000 wons. And the health assistant food is the most interesting item followed by Meet, Special products like a laver and mushroom, and an anchovy. in purchasing food at On-line market, customer thought that the confidence and the freshness of food are important because customer can't choose a product directly. In the future of food purchase using On-line shopping mall, 38.1% of people show their intend of purchasing at the mall. People who had experience of food purchase though the Internet have more positive view about repurchase than ones had not.

We developed a Off-Line Graphic Simulator which can simulate a robot model in 3D graphics space in Windows 95 version. 4 axes SCARA robot was adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed program. The interface between users and the off-line program system in the Windows 95's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D graphics.

The equipment of industrial robot in manufacturing and assembly lines has rapidly increased. In order to achieve high productivity and flexibility, it becomes very important to develop the visual feedback control system with Off-Line Programming System(OLPS). We can save much efforts and time in adjusting robots to newly defined workcells by using OLPS. A proposed visual calibration scheme is based on position-based visual feedback. The calibration program firstly generates predicted images of objects in an assumed end-effector position. The process to generate predicted images consists of projection to screen-coordinates, visible range test and construction of simple silhouette figures. Then camera images acquired are compared with predicted ones for updating position and orientation data. Computation of error is very simple because the scheme is based on perspective projection which can be also expanded to experimental results. Computation time can be extremely reduced because the proposed method does not require the precise calculation of tree-dimensional object data and image Jacobian.
