5-Arylamino-6-chloro-4.7-dioxoindazoles (DZs) were newly synthesized for the evaluation of antifungal activities. The compounds DZs were prepared by regioselective nucleophilic substitution of 5.6-dichloro-4.7-dioxoindazoles with appropriate arylamines in high yield. DZs were tested for their growth inhibitory activities against Candida species and Aspergillus niger. The MIC values were determined by the two-fold dilution method. In general. DZs showed in vitro antifungal activities. Among the tested compounds, DZ1, 3, 6, 7 and 12 showed potent antifungal activities against Candida species and Aspergillus niger. DZ7 was the most effective in preventing the growth of Candida species.

This paper aims to compare the performance of three phase induction motor drives using Five Leg Inverter (FLI) and Three Leg Inverter (TLI) configurations. An Indirect Field Oriented Control (IFOC) method using a TLI is well established and incorporated for high performance speed drives in various industries. The FLI dual motor drive system on the other hand shows good workability in the independent control of two induction motor drives simultaneously. In this experiment, the IFOC method is utilized for both drive systems, and Space Vector Pulse Width Modulation (SVPWM) is used to generate pulses for both inverters. For the FLI, the Double Zero Sequence (DZS) Injection technique is used to generate the modulation signal. The complete experiment setup is done by using a DSpace 1103 controller board. The individual motor performances are analyzed using similar schemes, equipment setups and controller parameter values. The results show similar speed performance response capability between the single motor operation using a TLI system and the two motor operation using a FLI system based on the variable speed range either in forward or reverse operation. They also show similar load rejection abilities. However, the single motor with a TLI has a better power quality aspect such as ripple current and total harmonics distortion (THD).

게임에서 괴물의 독특한 이미지와 사람들이 가지는 미지 사물에 대한 호기심 때문에 게이머들은 평범한 일상생활에서 벗어나 가상의 공간에서 게임의 새로운 세상을 탐구하게 한다. 게이머들은 현실 세계에 없는 괴물 캐릭터와 상대하면서 즐거움과 신선함을 느끼고, 이러한 독특한 캐릭터들은 게이머들에게 인기가 많다. 현재까지 게임 괴물 캐릭터에 대한 연구는 아직 미흡하다고 사료되어진다, 또한 현재 많은 게임캐릭터들 중에 괴물 캐릭터디자인을 단순한 조형적 디자인에 제한하여 단순디자인을 하는, 조형적 단순함을 표현한 괴물 캐릭터 디자인들이 주를 이루고 있다고 사료된다. 괴물캐릭터의 융복합 디자인을 다방면으로 분석하여 괴물캐릭터의 디자인에 조형적 적용사려를 적용하고자 한다. 본 연구는 전통적인 괴물 캐릭터 이미지를 바탕으로 괴물 이미지의 접목 방식을 다방면으로 연구하고자 한다.
