This paper deal with the shape design of the rotor and stator to maximize the torque density in Interior Permanent Magnet(IPM) Motor. We make various motor models to analyze torque density. Using the two-dimensional finite element method, these motor models are discussed under the same condition. As a result, we have found the better shape of model.

This paper in order to reduce the electric disaster damage which is caused by with electric equipment of traditional market developed the electric safety monitoring system which is suitable in traditional market. With for this did the actual condition investigation about electrical equipment of traditional market and we constructed Test-bed for testing reliability of electric safety monitoring system. Also experiment led in Test-bed and confirmed a stability. This paper following will be used with the data for the reliability security of the electric safe system operation which follows in the traditional market actual proof equipment construction which will be advanced.

In this paper, we discuss how to operate a buffer yard in an automated container terminal, which will be used for resolving the difficulties to which the interaction between external manned trucks and internal unmanned equipment led. The determination of fleet size of material handling equipment is an important issue in designing of buffer yard in automated container terminals. This research also addresses the issue of determining buffer capacities through simulation. By using response surface methodology (RSM) for efficient experimentation, the optimal combination of design parameters under applicable operational strategies is obtained.

IEC 62388은 선박용 레이더 시스템에 관한 국제 규격으로 국제해사기구의 새로운 성능기준인 Resolution MSC.192(79)의 의결에 따라 제정되었으며 2008년 7월 1일이후 선박에 설치되는 레이더 시스템은 해당 성능 표준을 만족하도록 권고하고 있다. 이에 따라 기존의 IEC 60936 시리즈 및 IEC 60872 국제 규격은 폐지되었다. 본 논문에서는 현재 MED 인증시 적용되고 있는 IEC 62388을 개략적으로 소개하여, 현행 규격에 의한 선박용 레이더 시스템 개발시 의무적인 필수 요구사항을 고찰하고자 한다.

Electric Vehicle Supply Equipment(EVSE) is a system or an equipment to supply electric power for charging the traction batteries on the electric vehicle. Control Pilot is an electric signal generated by EVSE and is transmitted to the electric vehicle by a vehicle coupler and a contact. The duty cycle of control pilot determines the maximum current to be drawn by electric vehicle. When the duty cycle is 5%, it is indicated that digital communication is needed. This paper deals with the data format and definition about communication scheduling through the inband signal on the control pilot of EVSE.

We develop some evaluation tool and indicators for the scores for medical equipment replacement in hospital. There has been no research for Korean hospitals although there are many for foreign medical institutions. In this paper, among many variables that were obtained from the previous studies, eleven variables are selected as indicators and tied as three groups. And then we obtain scores of medical equipments based on the weighted values of those indicators. We can make decisions whether we replace medical equipments or not by ranking the medical equipments based on the scores. This paper shows that we can make decisions to replace medical equipments very objectively and effectively using the evaluation tool and indicators we develop.

This study is proposed a new hybrid mount having a moving-magnet type electromagnetic actuator to reduce the vibration transmitted from naval shipboard equipment to the structure of the ship's hull. Optimal design specifications are determined through experimental analysis. The detailed design of the hybrid mount is determined through several design steps with electromagnetic numerical analysis using Maxwell Software(S/W). The hybrid mount that combines a rubber mount and an electromagnetic actuator has a fail-safe function for shock resistance. The mount is fabricated and tested using a universal testing machine to evaluate the design specifications. Finally, numerical simulation of the hybrid mount is performed to confirm control performance and applicability.

Currently, many research projects are focusing on automation of various equipment such as cranes and AGV's for automated container terminals. However, for more productivity of these terminals, integration of the required equipment is most crucial as proved in Computer Integrated Manufacturing (CIM). The integration requires information exchange via a type of network interconnecting various pisces of equipment. In order to better design such networks, this paper presents the requirements, available protocols, and basic network structure for an communication network in an automated crane terminal

Collagen, which accounts for one-third of human protein, is reduced due to human aging, and much attention is focused on making collagen into food to prevent such aging. Gel permeation chromatography with Reflective Index (RI) detection (GPC/RI) was chosen as the most suitable instrument to confirm molecular weight distribution, and we explored the use of this technique for analysis of collagen peptide molecular sizes and distributions. Data reliability was verified by matrix-assisted laser desorption/ionization coupled to time-of-flight (MALDI-TOF) mass spectrometric analysis. The data were considered meaningful for comparative analysis of molecular weight distribution patterns.
