식물검역선충 검사는 선충분리[직접검경→침지→체법→변형베르만깔대기법→해부현미경 검경]와 종 동정[해부현미경검경→표본제작→광학현미경검경, 해부현미경검경→분자생물학적 종 동정]으로 이루어진다. 선충분리는 깔대기법으로 식물체를 검사할 경우 시료양의 변화를 수용할 수 없으며, 여름철 고온기 부패로 선충 검출이 되지않는다. 이를 해결하기 위하여 침지법을 도입하여 해결하였으나, 높은 선충 검출율로 높은 검역처분이 가능하였졌으나,체법을 수행하는 과정에서 작업자에 따라 분리효율이 차이나고, 작업과정이 힘들어서 작업과정을 표준화 및 노동력절감이 필요하다. 이러한 문제를 해결하기 위하여 기계화 표준화를 위한 매뉴얼 체법 기계를 개발하였다. 그리고,작업과정에서 선충의 비산을 막으면서 선충을 쉽게 다룰 수 있는 노즐을 개발하였다. 또한 이러한 매뉴얼 체법기계와 노즐을 도입한 식물기생선충 분리 자동화 장비 사양 개발을 추진하였다. 최종적으로 [투입, 부유, 분리,수집, 보관, 세척, 모니터링 및 제어부]로 구성된 무인자동화 선충분리 시스템의 사양을 개발하였다.

This paper suggests a specific model that could efficiently improve the interaction and the interface between MES(Manufacturing Execution System) server and POP(Point of Production) terminal through electronic document server and electronic pen, bluetooth receiver and form paper in disassembly and process inspection works. The proposed model shows that the new method by electronic document automation system can more efficiently perform to reduce processing time for maintenance work, compared with the current approach by handwritten processing system. It is noted in case of the method by electronic document automation system that the effects of proposed model are as follows; (a) While the processing time per equipment for maintenance by the current method was 300 minutes, the processing time by the new method was 50 minutes. (b) While the processing error ratio by the current method was 20%, the error ratio by the new method was 1%.

Seafood is attracting attention as a future food industry. In recent years, the demand for fishery equipment of mechanization, automation, and unmanned was increased due to the environment affected by seafood processing, stricter regulations on safety, decline and aging of fishery worker. Ark shell (Scapharca subcrenata) was being produced in many steps in the production process. The process has been made such as collection–landing–washing–first sort (goods/non-goods)–transports– second sort (size). It was undergone first and second steps by delivering to the consumer. Here, the first step is to sort goods to collection and the second step is to sort by size. The fishery workers need ten people in first step and six people in second step. The workload of one hour per kg is 4,247 kg/h in first step and 2,213 kg/h in second step. In addition, the goods ratio by work process was 79% in first step and 98% in the second step. In this process, a lot of fishery worker and working time is needed. Therefore, this study developed elemental techniques for an automated size sorting system considering the working process problem, time and situation for washing and sorting of ark shell.

We present a legorization framework that produces a LEGO model from a voxel model. Unlike other frameworks, we include bricks whose height is more than one layer. Furthermore, we devise a two-colored graph that represents the adjacency and stability information of a LEGO model. Our legorization is composed of tiling process on each layer, which is implemented using a heuristic search algorithm. We legorize five models including characters and buildings to prove the excellence of out framework

In this study, design and manufacturing automation systems for the rolling stone rolling stone production were as follows. Manufacturing of rolling stone was designed to obtain a desired rolling round for about 5-15° by the tilted the tilted the slope of the road rolling barrel. This stone can be manufactured by the conflicting with each other inside the barrel. Additionally, the stone cutting device was made to cut the stone having the standard sizes of this rolling stone about 100x100x100 mm for height, width, depth, respectively. Rolling stone was transferred to a cutting device using a conveyor belt, while a rubber on the conveyor belt was used to prevent the slip between the stone and this conveyor belt. The production of this rolling stone device was measured by a counter system, which was installed at the end of the conveyor belt bottom of the outlet.

There is a growing concern on the improvement of water distribution pipeline for multi-regional water supply system in Korea along with its aging infrastructure. Rehabilitation of large diameter pipeline is more efficient in cost and time compared to replacement with trenching. The procedure for rehabilitation are diagnosis, cleaning, spraying coating material, and final inspection. The internal state of pipeline was carefully diagnosed and got C grade, which required rehabilitation. We found that 17,274,787,000 Korean won could be saved after pipe surface coating because of increased C coefficient of Hazen-Williams equation. Optimal coating material was D polyurea. We also found optimal distance between spraying nozzle and pipe wall to be 70 - 80 cm, which were critical factors for coating quality. This study also illustrated the time for spray drying to be more than 30 min. These results could be used in the quality control process during rehabilitation of aged pipelines.

선박에 설치되는 개구(Opening)는 사람이 드나드는 문(door)과 화물 출입구(cargo access hatch) 그리고 닫힌 장소에 사람이 드나들기 위한 맨홀(manhole)이 있다. 특히 해치는 수밀이 필요한 경우가 많아 폐쇄장치가 복잡한 기구로 구성되게 된다. 이 연구에서는 생산효율 및 품질향상을 위해 유압으로 작동하는 취부용 지그(JIG)를 개발하였다.

All games support the meaningful play, and each mechanism producing meaning is various. In mobile role-playing game, automation of in-game action standardizes movements of avatars and diversify combat challenges. Thereby players reinforce their avatars and make various repertoires so as to cope with different contents. Players predict the result of their own actions based on short-term, juicy feedbacks. In conclusion, mobile role-playing game has 'strategy' as its action mode while the unit time required for meaningful play is highly reduced. This analysis is significant in the sense that it was the first step toward integrated change of game play experiences.

Companies build the factory automation system to improve management effectiveness and productivity as prime strategies for sustainable growth. But most companies undergo various trials and errors while carrying out the project without elaborate preparation stage for factory automation. In this study, we tried to verify what factors are critical to effectively building distribution automation system, which is a branch of factory automation system. A consulting model for setting up a Material Handling Automation System by utilizing the Stage-Gate Process, which is product development process was studied. 29 material handling automation projects carried out between the year 1990 to 2013 at K-Company were selected. Interviews with the project managers, operators and maintenance personnels, various records and current status of the projects were used as data for structural equations based on the Milan consulting model and existing researches of factory automation, CIM for material handling automation. Creating effective basis of production, material handling system and energy saving system with expert review, when preparing a material handling automation project, help promote the project planning thus contributing to the performance of the resulting system, which appears though rather weakly in our data. Also the effect of material handling automation can be enhanced through sufficient and effective links to the relevant environments such as production logistics management and automated warehouses. More detailed planning characteristics of project promotion or some time-series data of effective Material Handling Automation System could enhace furthur studies. We propose a consulting model for setting up an efficient material handling automation system.

Design in small hydro power systems is the detailed work required a variety of epidemiological considerations. However, turbine designers were often feel the limitations due to repetitive calculations or drawings, rather than focusing on finding the turbine performance and efficiency improvements. Furthermore, miss the point in repeating the procedure design process or cross the interface is not easy to keep track of the changes required parameters should also feel the difficulties in efficient design. Improve this unreasonable points, though he design part is insufficient understanding of the hydro turbine, to automate the design to exclude the repetitive operations is the purpose of this study
