With the trend towards welding automation and robozation, mathematical models for studying the influence of various parameters on the weld bead geometry in Gas Metal Arc(GMA) welding process are required. The results of bead on plate welds deposited using the GMA welding process has enabled mathematical relationships to be developed that model the weld bead geometry. Experimental results were compared to outputs obtained using existing formulae that correlate process input variables to output parameters and subsequent modelling was performed in order to better predict the output of the GMA welding process. The aim of this work was to explain the relationships between GMA welding variables and weld bead geometry and thus, be able to predict input weld bead size. The relationships can be usefully employed for open loop process control and also for adaptive control provided that dynamic sensing of process output is performed.

The high-precision laser scriber carries out scribing alumina ceramic substrates for manufacturing ultra-small chip resistors. The ceramic substrates are loaded, aligned, scribed, transferred, and unloaded. The entire process is fully automated, thereby minimizing the scribing cycle time of the ceramic substrates and improving the throughput. The scriber consists of the laser optical system, pick-up module of ceramic substrates, pre-alignment module, TH axis drive work table, automation module for substrate loading / unloading, and high-speed scribing control S/W. The loader / unloader unit, which has the greatest influence on the scribing cycle time of the substrates, carries the substrates to the work table that carries out the cutting line work by driving the X and Y axes as well as by adsorbing the ceramic substrates. The loader / unloader unit consists of the magazine up / down part, X-axis drive part for conveying the substrates to the left and right direction, and the vision part for detecting the edge of the substrate for the primary pre-alignment of the substrates. In this paper, the laser scribing machining simulation is performed by applying the instrument mechanism of each component module. Through this study, the scribing machining process is first verified by analyzing the process operation and work area of each module in advance. In addition, the scribing machining process is optimized by comparing and analyzing the scribing cycle time of one ceramic substrate according to the alignment stage module speed.

Image morphing deals with the metamorphosis of one image into another. The field morphing depends on the manual work for most of the process, where a user has to designate the control lines. It takes time and requires skills to have fine quality results. It is an object of this paper to propose a method capable of realizing the semi-automation of field morphing using adaptive vertex correspondence based on image segmentation. The adaptive vertex correspondence process efficiently generates a pair of control lines by adaptively selecting reference partial contours based on the number of vertices that are included in the partial contour of the source morphing object and in the partial contour of the destination morphing object, in the pair of the partial contour designated by external control points through user input. The proposed method generates visually fluid morphs and warps with an easy-to-use interface. According to the proposed method, a user can shorten the time to set control lines and even an unskilled user can obtain natural morphing results as he or she designates a small number of external control points.

In this work, we propose a new framework of robot control for a variety of applications to our unstructured everyday environments. Programming robots can be a very time-consuming process and seems almost impossible for ordinary end users. To cope with this, this work is to provide a software framework for building robot application programs automatically, where we have robots learn how to accomplish a commanded task from the object. An integrated sensing and computing tag is embedded into every single object in the environment. In the robot controller, only the basic software libraries for low-level robot motion control are provided from the robot manufacturer. The main contributions of this work is to develop a server platform that we call Omniscient Server that generates the application programs and send them to the robot controller through the network. The object-related information from the object server merges into robot control software to generate a detailed application program based on the task commands from the human. We have built a test bed and demonstrated that a robot can perform a common household task within the proposed framework.

농업용 드론은 경제적 효율성으로 인해 활용도가 점차 증가하고 있으며, 비행을 담당하는 본체와 약제를 방제 대상까지 전달하는 임무를 담당하는 분무 시스템으로 구성되어 있다. 따라서 드론을 활용한 농약 방제 작업 시 농작물에 대한 환경과 특성이 고려되어야 하며, 이에 따른 체계화된 비행 고도, 속도 및 분사 시간 등 조건이 달라져야 한다. 농업용 드론을 이용한 방제 작업은 조종자의 운용에 의존하고 있으며, 운용 숙련도에 따라 살포 효과 및 영향에 차이가 발생한다. 또한 농업용 드론에 관해 운용 기준 및 방제 효율 등의 편차가 발생하여 방제 작업 분야에서 농업용 방제 드론의 보급을 저해하는 요소로 작용하고 있다. 이에 본 연구에서는 농업용 드론의 살포 특성을 파악하여 유효 살포 시간 및 간격을 적용하고, 선행 연구와 비교하여 방제면적 산출이 가능한 체계를 실험적으로 검증하려 한다. 이러한 실험적 검증을 통해 농업용 드론에 운용 방식 및 체계화된 수치를 적용하여, 방제 작업의 저해요인을 최소화하여 최적의 방제 공정을 적용하고자 한다.

Purpose: This research is to find a solution for educational work on high blood pressure control in public health centers by analyzing their current status. Method: It analyzed data from 133 public health centers that had been doing educational work on high blood pressure, through a questionnaire. Also, it developed recommendations by converging opinions from an expert group made of 25 people with nominal group technique. Result: The educational methods of public health centers did not make any approach to get to the goal of the work. The mass media education and campaign activities for the general public had just temporary and passive propensities. In education for patients, it did not use appropriate methods to present management techniques for diagnosis process of patients, medication management, self monitoring BP, and risk factors. Pocket book for monitoring high blood pressure was not focused on self-recording for self-management. The expert group recommended that educational materials for adults should be developed focusing on treatments and observance of risk factors through daily living, and those for children should be focused on basic understanding about diseases, and life style. Conclusion: Presenting direction and strategy of fundamental education work is needed for public health centers by giving them standard educational guidelines of managing high blood pressure nationally, and it is desirable that fundamental frameworks of educational materials should be developed and distributed by professional groups nationally.
