There has been requested to automate the welding process in shipyard due to its dependence on skilled operators and the inferior working environments. According to these demands, multiple robot welding system for sub-assembly welding line has been developed, realized and installed at Keoje Shipyard. In order to realize automatic welding system, robots have to be equipped with the sensing system to recognize the position of the welding panels. In this research, a camera vision system is developed to detect the position of base panels for subassembly line in shipbuilding. Two camera vision systems are used in two different stages (Mounting and Welding) to automate the recognition and positioning of welding lines. For automatic recognition of panel position, various image processing algorithms are proposed in this paper.

In order to realize automatic welding system, robots have to be equipped with a sensing system to recognize the position of the welding panels. In this research, a camera vision system(CVS) is developed to detect the position of base panels for sub-assembly line in shipbuilding. Two camera vision systems are used in two different stages (fitting and welding) to automate the recognition and positioning of welding lines. For automatic recognition of panel position, various image processing algorithms are proposed in this paper.

In this paper the sway-control problem of a container crane is investigated. The control loop is divided into two stages. The first stage is a modified time optimal control for trolley traversing. The velocity command for trolley traversing consists of three components ; a reference velocity and two feedback signals for compensating the deviations of trolley and sway angle from their desired trajectories. For trolley's exact positioning the trolley dynamics is identified via an error equation identifier structure. The second stage is a nonlinear residual sway control that starts at the end of first stage. The control design for the second stage is investigated from the perspective of controling an underactuated system, and the control law combines the feedback linearization and variable structure control.

As optical fiber communication grows, the fiber alignment become the focus of industrial attention. This greatly influence the overall production rates for the opto-electric products. We proposed multi-axis nano positioning stage for optical fiber alignment. This device has 3 DOF translation and sub nanometer resolution. This nano stage consist of 3 PZT-driven flexure stages which are stacked parallel. The displacement of it is measured with capacitance gauge and is controlled by computer-embedded main controller. The design process of flexure stage using FEM is proposed and the performance evaluation of this system is verified with experiments.

An ultra-precision stage is used in many industrial areas such as precision machine tools or semiconductor apparatus. These stages used to be driven by piezoelectric actuators in order to obtain ultra precision positioning resolution. Piezoelectric actuator can be moved fast in nanometer resolution. However, it has relatively large non-linear characteristics like hysteresis and creep curve. Although several kinds of control techniques have been developed, controller design method is still complicated. In this paper fuzzy control rules are developed intuitively. In order to verify the performance a series of experiments were conducted and the results were compared with those of the PID controller case.

Mobile service, which is related to all stages of supply chain, can enhance the efficiency of perception and response of the participants. The advantage of mobile service is ubiquity, speed, traceability, positioning, personalization and safety. The purpose of this paper is to propose an overall framework utilizing mobile service in SCM. In the areas of inventory management, remote diagnostics, communications with field workers, and order fulfillment, customer-centric mobile supply web is proposed and implemented for the wireless warehousing and replenishment system.

A robust minimum-time control (RMTC) strategy is addressed and it is extended to the dual-stage servo design. Rather than conventional switching type sub-optimal controls, it is a reference following control approach where the predetermined minimum-time trajectory (MTT) is tracked by the perturbation compensator based feedback controller. First, the minimum-time trajectory for a mass-damper system is derived. Then, the perturbation compensator to achieve robust tracking performance in spite of model uncertainty and external disturbance is suggested. The RMTC is also applied to the dual-stage positioner which consists of coarse actuator and fine one. To best utilize the actuation redundancy of the dual-stage mechanism, a null-motion controller to actively regulate the relative motion between the two stages is formulated. The performance of RMTC is validated through simulation and experiment.

Recently in the field of precision positioning device, the contact-free stages are gaining focuses with their outstanding performances by eliminating mechanical frictions. This paper presents the driving algorithm for contact-free linear stage based on switched reluctance principle. The proposed driving algorithm has a similar structure of that of switched reluctance motor but this study has its own originality in terms of reducing the normal farces and force ripple at the same time. The simulation and experiment are executed to verify the proposed algorithm.

In this study, the objectives are to provide rural experience tourism village business courses and development direction in between individual farmers and the village in base on rural development business of Hapjeon-village. The developmental process of a farm-stay village can be categorized into the period of six stages: 1) a conception stage 2) an adoption stage 3) a growth stage 4) an expansion stage 5) a stagnation stage 6) a recovery stage. Farm Stay Villages, Individual Farmhouses or Producer Groups can be placed in four different quadrant areas of a graph, depending on the pursuing direction and results of core values by having the X-axis for economic factors (public profits, individual profits) and by having the Y-axis for emotional factors (self-actualization, conflicts). The first quadrant area is designated for ideal individual farmhouses and producer groups for having achieved the status of economic self-reliant and high emotional satisfaction. The second quadrant is for ideal self-actualized communal villages having achieved the independent public interest and public profitable status. The third quadrant is reserved for villages experiencing communal conflicts and no economic self-reliant stagnant status. The fourth guardant area is allocated for individual farmhouses and producer groups having achieved self-reliant economic status, yet having communal conflicts. Using the aforementioned concept, the government shall design village development projects and prepare realistic and achievable goals and place them in as a systematic device in future projects.
