Dynamo based vehicle inspection device is end of line device for automobile industry. The device is utilized as implementing vehicle functionality inspection such as brake force, cruise control, kick-down acceleration, CAN inspection. As dynamo based inspection device is broadly adopted in automobile industry, the dynamic study is required to verify the vehicle test equipment reliability. This research recommends appropriate dynamic brake force inspection procedure and theoretical background for developed equipment. Dynamic characteristic of brake force implementation to roller is simplified. With simplified characteristics, the indirect brake force measurement strategy is developed and adopted. Comparison of each brake force result, the appropriate brake force inspection criterion is given.

Even though the logistics infrastructure has been strengthened gradually, most of countries usually have a logistical dead-zone problem which the delivery demand cannot be fully fulfilled on time via conventional transportation vehicles (i.e. trucks) due to the intrinsic geographical conditions. Demand in either small islands or mountainous regions might be hardly fulfilled by logistics providers in comparison with other delivery areas. In this paper, we tried to show the possibility of a drone-assisted logistics services for the logistical dead-zones. Through indepth discussions and simple survey with the related experts, we propose several alternatives for the drone-assisted logistics services and then evaluate those alternatives in terms of feasibility, (operating) convenience, and flexibility (the possibility of future extension). This exploratory study has been conducted using a real world case of South Korea.
운전 조건을 고려한 매입형 영구자석 동기전동기의 영구자석 와류손 해석

차량 구동과 같이 광범위한 속도 영역에서 높은 출력을 요구하는 견인 전동기 분야에 적합한 전동기로 현재는 매입형 영구자석전동기(Interior Permanent Magnet Motor : IPM)가 가장 각광 받고 있다. 그러나 차량용 전동기는 고속에서 고출력을 발생시켜야 하기 때문에 높은 구동 주파수와 큰 전류를 사용한다. 이러한 특성은 철심의 자기포화 특성을 발생시키고, 전동기의 효율을 떨어뜨리는 원인이 된다. 또한 차량의 높은 주변환경 온도 때문에 고속 동작에서 약계자 제어 시 전기자 반작용에 의한 영구자석의 불가역 감자가 발생할 수도 있다. 따라서, 본 논문에서는 차량용 IPMSM의 설계를 수행하였으며, 차량의 운전 조건을 고려하여 전동기의 철손 해석을 수행하였으며, 불가역 감자 현상을 피하기 위한 영구자석의 와류손 해석을 수행하였다.

The purpose of this study is to understand Archigram`s architectural works by analyzing Archigram, which was a little magazine issued from 1961 to 1974. Studies on the Archirgam`s architectural works have been mostly focused on their projects themselves, not within the context of the medium, Archigram (little magazine). However, Archigram as a little magazine worked as a platforms where ideas and projects could be developed and communicated among the members. Therefore, this study focused on the distinct features of Archigram`s architectural works which were influenced by its little magazine, Archigram. The major conclusion of this study is that Archigram`s architectural works worked as media themselves; Archigram`s architectural works are open-end conclusions which can be transformed and developed by other members; Archigram members created new temporality, creating `up-to-the-minute` architecture.
