사설안내표지판은 공공디자인의 영역으로 시민들의 편의를 돕고 도시미관을 고려해야 하지만 제도화된 디자인 규정이 없는 행정적인 문제와 관리 주체들의 인식 부족으로 무질서한 난립을 초래하여 도시 미관을 해치고 정보 혼란을 야기하는 주요 원인이 되고 있다. 이러한 문제로 서울시를 비롯한 각 지방 도시들은 사설안내표지판 디자인 관리지침을 만들어 개선사업을 진행하고 있으나 개선 후 안내표지판의 실질적인 디자인 만족도 검증의 연구가 부족한 실정이었다. 이에 본 연구에서는 사설안내표지판의 디자인 관리지침을 만들어 개선 사업을 실시한 대전시를 중심으로 개선 후 표지판의 시각요소, 정보전달, 도시 가로환경에 대한 디자인 만족도에 대해 조사하고 분석해보았다. 분석 결과 시각요소, 정보전달, 도시 가로환경의 모든 항목에서 개선 후 디자인의 만족도가 높게 나타나 긍정적인 평가를 받는 것으로 판단되며 사설안내표지판 디자인 만족도의 실증적 조사에 의의가 있다고 사료된다.

In this study, anthropometric analysis and usability evaluation for four-wheeled walker were carried out and then ergonomics design guidelines were proposed. In anthropometric analysis, design factors of four-wheeled walker were firstly identified and anthropometric design guidelines were made using Korean human scales. Design suitability for two typical four-wheeled walkers was analyzed in based on anthropometric design guidelines. Usability evaluation for two typical walkers was also performed through observation method and expert evaluation. Several usability problems were identified and design solutions were proposed for the design improvement of four-wheeled walker. Finally a design model of four wheeled walker considering analysis results was proposed.

Now days, the marketing environment is rapidly changed. Therefore, a lot of companies try to reduce production cost. Especially, Design is a important activities in new product development. While the concepts of design for manufacturable and concurrent engineering have made significant advances in integrating the design function with other areas in the firm. There are still major gaps in timely and accurate costing information available to designers. Inappropriate design could result in high redesign cost and delay in product relation. The generation of design and improvement is a time-consuming and mentally exhaustion process. It involves combining design features to generate as many potential design as possible. As not all features combinations are feasible, decision-makers have to narrow down the potential solutions and subsequently select appropriate design for further development. This new study is composed of 3 steps aiming at the Low Cost Design of the product. The three steps are consisted that setting up the target Cost, estimating the current functional cost, the design of a unit's reviewing according to the priority of the difference between the target cost and the functional cost.

Today, the statistical process control (SPC) in manufacture environment is an important role at the process by the productivity improvement of the manufacturing systems. The control chart in this statistical method is widely used as an important statistical tool to find the assignable cause that provoke the change of the process parameters such as the mean of interest or standard deviation. But the traditional SPC don't grasp the change of process according to the points fallen the near control limits because of monitoring the variance of process such as the fixed sampling interval and the sample size and handle the cost of the aspect of these sample point. The control chart can be divided into the statistical and economic design. Generally, the economic design considers the cost that maintains the quality level of process. But it is necessary to consider the cost of the process improvement by the learning effects. This study does the economic design in the VSI $\bar X$ control chart and added the concept of loss function of Taguchi in the cost model. Also, we preyed that the VSI $\bar X$ control chart is better than the FSI $\bar X$ in terms of the economic aspects and proposed the standard of the process improvement using the VSI $\bar X$ control chart.

본 연구는 대학도서관에서 제공하는 서비스 가치를 극대화하기 위하여 서비스디자인 방법론을 대학도서관에 적용하였다. 이를 위하여 서비스디자인 모형인 '더블다이아몬드모델'(Double Diamond Model)을 대학도서관에 적용, 서비스디자인 도구인 퍼소나(Persona), 고객여정지도(Customer Journey Map), 터치포인트(Touch Points)를 활용하였다. 서비스디자인을 대학도서관에 반영하기 위하여 주제와 관련된 문헌 및 선행연구를 고찰하였으며, 설문조사 및 이용자와 사서면담, 현장조사를 통해 상황별 이슈를 발견하고 퍼소나와 상황시나리오를 도출하였다. 나아가 설정된 퍼소나의 상황별 행동과 이용자의 감정변화에 대한 정보를 종합하여 이를 고객여정지도로 시각화하고 3개 분야 11개 항목의 서비스 개선안을 제안하였다. 본 연구는 특정 서비스를 개선하기보다 서비스 개선방안을 도출하기까지의 과정에 주안점을 두었다. 또한, 대학도서관 서비스개선 및 새로운 서비스 방안을 제시하는 것이 본 연구의 목적이었다. 이를 통해 실질적인 서비스 개선 방안을 대학도서관에 적용하였다는 것에 본 연구의 의의가 있다.

Heavy-weight head slides may cause excessive inertia impact ＆ moment on the machine tool structure when they move or stop abruptly during operation. Consequently these inertia impact and unbalanced moment bring transient vibrations and rough sliding motions on the machine structure. Machine tool engineers have tried many kind of feed-slide designs in order to solve this problem; for example, the design optimization of the moving structure for minimum weight and maximum stiffness, box-in-box type slide design, and so on. In this article, force and moment equilibrium equations regarding to the inertia force ＆ moment were derived for each one of a mold M/C's head slides. Furthermore, five different design configurations of head slide assembly were reviewed for its design improvement regarding to force ＆ moment calculations and finite element structural analysis results.

This paper addresses several issues concerning the analysis, design, modeling, simulation and development of single-phase, single-switch, power factor corrected AC-DC high frequency switching converter topologies with transformer isolation. A detailed analysis and design is presented for single-switch topologies, namely forward buck, flyback, Cuk, Sepic and Zeta buck-boost converters, with high frequency isolation for discontinuous conduction modes (DCM) of operation. With an awareness of modem design trends towards improved performance, these switching converters are designed for low power rating and low output voltage, typically 20.25W with 13.5V in DCM operation. Laboratory prototypes of the proposed single-switch converters in DCM operation are developed and test results are presented to validate the proposed design and developed model of the system.
