  • This paper develops a novel automatic parking algorithm based on a fuzzy logic controller with the vehicle pose for the input and the steering rate for the output. It localizes the vehicle by using only external sensors - a vision sensor and ultrasonic sensors. Then it automatically learns an optimal fuzzy if-then rule set from the training data, using an evolutionary fuzzy system. Furthermore, it also finds the green zone for the ready-to-reverse position in which parking is possible just by reversing. It has been tested on a 4-wheeled Pioneer mobile robot which emulates the real vehicle.

  • For the supported high-technology, it is in need of estimation about power quality and reasonable price through machinism. The power system made much of precision digital industrial damage under sag. This study suggested electric machine under effects of power quality in the theory and test. A electric machine was simulated and experimented about sag. The test system made up IPC as voltage sag device. The test machine was magnetic contactor and PLC. The result, electric machines appeared to influence sag with CBEMA curve. It was make possible analysis of power system about a fault. This study was expected to method that investment and development of equipment on power market in the future.

  • This study showed a way to develop web site of shopping mall through systematic identification of the interface elements affecting user's performance and subjective sensibility for Internet shopping mall. To quantify the effects of factors, simulators were designed and used in experiments. It was shown that location of 'Table of Contents'(left > right = up = down) and 'Menu' type(non_Drop down and page Movement = Drop down and page Movement > Drop down and non_age Movement) were the significant factors. However, whether 'Frame' was used or not, there was no significant difference. Also, in the evaluation of subjective sensibility, 'Background color' was a significant factor. And for 'Header & Scanning Column color', yellow color had a tendency to enhance satisfaction for 'simplicity', while green or blue color strengthened 'balance' feeling. But 'text style' was not significant.

  • Energy saving is as important as developments of green energy and alternative energy. The need for development of high-efficiency lighting apparatus further increased. This paper compared with the size of electrical equipment and analyzed the size of electrical capacity for the railway station building. Also discussed energy saving measures that can be achieved by using high-efficacy lighting fixtures, and the percentage of the lighting load capacity of the entire building.

  • 지구 온난화가 심화되면서 국제적으로 기후변화 협약에서는 한층 강제력 있는 온실기체의 감축목표를 권고하고 있다. 지난 1998년에 교토 기후협약에 가입한 우리나라도 실질적인 감축목표를 결정해야 하고 능동적으로 대처해야 하는바, 이를 소홀히 한다면 무역뿐만 아니라 산업활동에도 차질이 빚어질 것이다. 이를 위해 가장 기본적인 자료라 할 수 있는 온실기체($CO_2$, CH$_4$, $N_2$O, CFCs, PFCs)의 지속적이고도 체계적인 관측과 세계적으로 인정받을 수 있는 정확한 측정값의 제시가 필수적이다. (중략)

  • Through the courses of industrialization, speedy growth and pluralism. The problems about the environment- friendly structures have become very important problem. Especially, it is getting highly appear to the expectation about the environment friendly buildings in Kangwon-do where has greacefully clean environment. The guide line for Kangwon-do can be arranged to the following through the varity analysis, outside enviroment, color, construction materials, outside design etc the guide line for Kangwon-do can be arranged as to the followings. It appears to be suitable to country houses in kangwon-do that is made of timber or red-bricks with green half circled roof and give a sense of warmth and soft. but the coastal area village is appeared wave style roof with orange color and surrounded by natural building stones or a line- plastered wall making complicated.

  • The paper presents two novel concepts of increasing the energy storage capacity at pumped storage power plants, both existing and new projects. The concepts utilize compressed air as a working medium to displace water from a volume originally not available for storage. The concepts are likely to give additional storage volume at a low cost, however, much development and many investigations are needed before the concepts can be shown to be technical and economical feasible solutions for energy storage. The concepts are disclosed so that researchers and utilities can start those investigations, hopefully helping the green transition by providing highly valuable energy storage for a future renewable energy having a much higher share of renewable energies than the current systems.

  • A DNA construct containing rat T $\alpha$ 1 $\alpha$ -tuulin gene 5'-flanking sequence and GFP reporer gene was microinjected into 1-cell loach embryos. Neuron-specific FGP expression was observed in developing loach embryos and early stage fry. The results demonstrated that rat T $\alpha$ 1 $\alpha$ -tubulin gene promoter may be sufficient to specify gene expression to neurons in loach embryos. Thus, the use of GFP reporter controlled by T $\alpha$ 1 $\alpha$ -tubulin gene promoter may facilitate visualization of the dynamic processes of neural tissue development.

  • Generally, The women was used in the cosmetic cushion fact. It has developed with the consideration of manufacturing. In this study, we designed green-friendly and element parts lower and single cushion fact containers using a single material. Injection mold simulation were performed using on 3D design data. The injection mold simulation used the data (Injection time / Cooling time / Temperature / Pressure) in the injection mold parameters. In addition, the sink mark phenomenon in the simulation results is analyzed as a problem due to the thickness and further research is needed in the future.
