This paper is concerned with the optimization of the drive for linear-guide press which is one of mechanical presses. The design of linear-guide drive for a mechanical press is introduced and the drive for the linear-guide press is optimized for the improvement of load and velocity characteristics. As a result of optimization, the load capacity during stroke increases and the slide velocity decreases in working region, respectively. The new design could be suited to many applications in precision forming such as extrusion and the sheet metal-forming processes.

Background: The present study introduces the design and fabrication of a simple surgical guide with which to perform genioplasty. Methods: A three-dimensional reconstruction of the patient's cranio-maxilla region was built, with a dentofacial skeletal model, then derived from CT DICOM data. A surgical simulation was performed on the maxilla and mandible, using three-dimensional cephalometry. We then simulated a full genioplasty, in silico, using the three-dimensional (3D) model of the mandible, according to the final surgical treatment plan. The simulation allowed us to design a surgical guide for genioplasty, which was then computer-rendered and 3D-printed. The manufactured surgical device was ultimately used in an actual genioplasty to guide the osteotomy and to move the cut bone segment to the intended location. Results: We successfully performed the osteotomy, as planned during a genioplasty, using the computer-aided design and computer-aided manufacturing (CAD/CAM) surgical guide that we initially designed and tested using simulated surgery. Conclusions: The surgical guide that we developed proved to be a simple and practical tool with which to assist the surgeon in accurately cutting and removing bone segments, during a genioplasty surgery, as preoperatively planned during 3D surgical simulations.

서울시 지하철 객실에 설치된 안내전광판은 현재 한국어·영어·중국어·일본어 4개 국어로 역사와 전동차 내 설치된 LCD 모니터를 통해 주요 정보나 운행정보를 알리는 안내방송을 실시하고 있다. 하지만, 지하철 객차 안내 화면이 운행 정보보다 광고를 더 비중 있게 표시하는 탓에 이용자들이 혼란을 겪고 있다. 연구 방법으로는 현재 서울 지하철에 설치된 안내전광판의 현황과 문제점을 파악하고 개선된 새로운 안내전광판 시안을 제시해 서울시 지하철을 주로 이용하는 이용객 10대부터 60대까지 67명을 대상으로 온라인 설문조사를 실시하였다. 연구 결과, 탑승한 노선마다 화면 디자인이 달라 필요한 정보만을 제공하는 안내전광판 통일이 필요하다. 특히 이용객이 각지에서 이동하기 위해 지하철을 여러 번 환승하므로 안내전광판 디자인은 광고전광판이 아닌 긴급 재난안내나 승하차 정보의 기능을 해야 한다.

A reactor protection system (RPS) plays the roles of generating the reactor trip signal and the engineered safety features (ESF) actuation signal when the monitored plant processes reach predefined limits. A Korean project group is developing a new digitalized RPS and the Cabinet Operator Module (COM) of the RPS which is used for the RPS integrity testing and monitoring by an equipment operator. A flat panel display (FPD) with a touch screen capability is provided as a main user interface for the RPS operation. To support the RPS COM user interface design, actually the FPD screen design, we developed a user interface style guide because the system designer could not properly deal with the many general human factors design guidelines. To develop the user interface style guide, various design guideline gatherings, a walk-though with a video recorder, guideline selection with respect to user interface design elements, determination of the properties of the design elements, discussion with the system designers, and a conversion of the properties into a screen design were carried out. This paper describes the process in detail and the findings in the course of the style guide development.

An analytic design guide was formulated for the design of 3-stage CMOS OP amp with the nested Gm-C(NGCC) frequency compensation. The proposed design guide generates straight-forwardly the design parameters such as the W/L ratio and current of each transistor from the given design specifications, such as, gain-bandwidth, phase margin, the ratio of compensation capacitance to load capacitance. The applications of this design guide to the two cases of 10pF and 100pF load capacitances, shows that the designed OP amp work with a reasonable performance in both cases, for the range of compensation capacitance from 10% to 100% of load capacitance.

Objective: This study is to develop a design and evaluation guide to the ergonomic design of the farm working convenient equipments in order for the elderly to use them easily and safely. Background: The aging population has already increased in farm villages. But due to the usage of the farm working equipments that did not reflect the characteristics and functional changes of aging, accidents and patients with disease are increasing. Method: The study investigated the functional changes and physical, cognitive, and sensuous characteristics of the aged. By determining the criteria for classification of the convenient equipments by crop, and by finding out the items necessary for the ergonomic design, a guide to this study is proposed. Results: It is obvious that the physical, cognitive and sensuous functions change as the aging process continues. Therefore, for the design and evaluation of Control Panel, Control Lever, Frame Size, Shape, and Equipment Weight that are the necessary items for the ergonomic approach for the farm working equipments, such characteristics have to be reflected. Conclusion: Through this study, a guide to the design and evaluation of convenient equipments for the farm works that reflected the aging characteristics and functional changes has been proposed. Application: The result of this study is to expect not only designers but also related specialists to make the best use of it.

To meet the demand of higher handling capacity, a mixed-flow submersible deep well pump was designed and tested. The main hydraulic components are made of plastics, which is free of erosion, light-weight, and environment-friendly. To simplify plastic molding process, and to improve productivity, an axial-radial guide vane was proposed. To clarify its effect on the performance, a radial guide vane and a space guide vane are developed as well. By comparison, the efficiency of the pump equipped with the axial-radial guide vane is higher than the radial guide vane and is lower than the space guide vane, and its high efficiency range is wide. The static pressure recovery of the axial guide vane is a bit lower than the space guide vane, but it is much larger than the radial guide vane. Taking the cost and molding complexity into consideration, the axial-radial guide vane is much economic, promoting its popularity for the moderate and high specific speed submersible deep well pumps.

임플란트 식립 시 수술 가이드는 치료계획 수립 및 진단 뿐 아니라 식립 위치 및 각도를 조절하는데 도움을 준다. 수술 가이드는 식립 위치만 보여 주는 디자인(Nonlimiting design), 식립 위치와 각도를 보여주는 디자인(Partially limiting design), 식립 위치와 각도 및 깊이까지 보여주는 디자인(Completely limiting design)으로 나뉜다. 식립 위치와 각도를 보여주는 디자인은 제작이 비교적 간단하고 비용이 적게 드는 반면 식립 위치와 각도 및 깊이까지 보여주는 디자인보다 수술 정확성이 떨어진다는 단점을 가진다. 식립 위치와 각도 및 깊이까지 보여주는 디자인은 해부학적으로 정확하고 보철적, 생역학적 관점에서 최적화 된 치료를 할 수 있으며 심미적, 기능적으로 술 후 불편감을 최소화 해줄 수 있다. 본 논문에서는 다양한 수술 가이드에 대하여 문헌을 통해 고찰해보고 이를 임상에 적용한 증례를 살펴보고자 한다.
