The mechanism design of the interactive emotional robot has been carried out. The two-wheeled inverted pendulum type mechanism was adopted to improve the mobility and make the innate clumsy monoaxial bicycle motion. Even though the system is unstable in itself, it is expected for the robot to move freely in a plane, keeping the upright position only with two wheels. Two motors attached on head can make 4 motion sets, and two motors on the wheels can make 8. Therefore, 32 independent motion sets can be achieved from the robot to communicate the emotions with humans. The motion's equation of the robot was derived based on nonholonomic dynamics, and the necessary power to the wheel's rotational axis was found by simulation.

In this paper, I have approached the problem of scheduling that can be reasonably cost down and duration down in the tenement house by using PERT/CPM technics. The tenement house of 'M' construction company consistute 78 element workings in total. I made out the net-work scheduling through 78 element workings, after calculating by computer, G-COS 101, I reduced the duration and cost by MCX, and then enforced from the least cost slope to six times. Resulty, I attained PERT/CPM scheduling for construction scheduling ; a) Make Possible the effectiveness budgeting control b) How the scientific materials c) Make possible the reasonably decision making d) Strengthen the material control by relevance of element workings e) Make possible the duration down through the least cost.

A current environmental issue, 'Enviromentally Sound and Sustainable Development(ESSD)' is very important in that it is for our common future. Environmental education is essential as a long-term strategy to realize sustainable environments and society. So we developed a new program about ESSD. The purposes of development were as follows. First, introduce ESSD to students, second, make them know ESSD appropriate to our nation, third, make change from economy-centered thoughts to environmental economy-centered thoughts, ultimately make form behaviors related to ESSD. To verify the effects of new developed program, the direct learning was carried out by 212 students in total. Post test scores of experimental groups were significantly higher than those of control groups about four goals, respectively. Therefore this program is effective to achieve four goals of environmental education for ESSD.

The purpose of this paper is to make clear the relation of traditional religion with economic ethics and attitude in Japan. I selected Shimhak(心學) of Japanese traditional religions to analyze because it has been said that Shimhak was related to the modern ethics of merchants in Japan. The contents of this paper is composed of two parts. First, the religious character of Shimhak is discussed. I will analyze the relation of Shinto, Buddhism and Confucianism to Shimhak to certify the syncretism of Japanese religion. Second, the economic ethics of Shimhak is discussed. I will make clear the historical significance of Shimhak in modern Japan, and the relation of the economic ethics of Shimhak with the spirit of Japanese capitalism. This paper will be useful to make out the social influence of Japanese traditional religion, to estimate the sustaining mode of traditional value and ethics in Japan in the future.

In this paper, to improve performance of spectrum sensing, we propose the method which can find optimal threshold based on power of PU(Primary User) signal. To find optimal threshold value, we will use mathematical method, and find threshold which can has lowest error probability. Each SU(Secondary User) use this threshold and All Su makes local decision. All Su Send local decision to FC(Fusion Center). In this paper we consider K-out-of-n rule to combining local decision. To make global decision value, FC find optimal n. In the FC. FC received local decision which has lowest error probability and using optimal n and these vaule. FC make global decision value. In this paper, to analysis performance proposed scheme, we simulate proposed scheme using matlab and compare with traditional OR Rule. As a result of simulation, we can know that preposed scheme can get a better performance than traditional OR rule.

The purpose of this research is to analyse the process of development and verification of 'National Competency Standards' of Hanbok production, which was carried out in 2013 for the fashion industry. As the result of this research, the definition of the duty in Hanbok production is 'to conduct a series of step-by-step processes of planning and developing fabric and design, then making pattern, cutting fabric and sewing.' The competency unit for Hanbok production is analyzed in 10 categories: analysis of market trends, design plan, production and manipulation of fabric, production process plan, sample making, pattern making, cutting out, sewing, finishing sewing, inspection of the product quality. Competency unit elements of each competency unit are as follows. 1) analysis of market trends: to research market trend resources, to analyse consumers' buying trend, to analyse industry changes, 2) design plan: to develop design, to plan fabrication, to draw flats, 3) production and manipulation of fabric: to develop fabric planning, to prepare fabric manipulation, to conduct fabric manipulation, 4) production process plan: to grasp design, to plan sewing method, to prepare a specification sheet, 5) sample making: to make a sample pattern, to cut sample fabrics, to sew sample, to finish sample making, 6) pattern making: to measure body, to make production pattern, to adjust production pattern, 7) cutting out: to care fabrics, to lay out patterns, to cut out fabrics, 8) sewing: to sew a garment, to sew a lining, to attach a lining, 9) finishing sewing: to neaten edges, to attach trims, to press to finish, 10) inspection of the product quality: to confirm correspondence with the specification sheet, to inspect appearance.

This paper deals with the experimental study of the turbulent characteristics in the swirling coaxial Jets. In this research, the experimental study has been carried out to investigate the effects of swirl number and equivalence ratio on the flow characteristics in nonreacting flow field of the model combustor which symplifys the continuous type combustor for the practical use. Author particularly Intends to find out the fuel-air mixing In the recirculation zone In order to make sure the effects of swirl number and equivalence ratio on the stabilization of flame.

Diamond grit was coated with Ti by RF Sputtering to investigate the effect of coated diamond particles on performance of diamond impregnated saw. Coated and uncoated powders were separately mixed with 70Co-30W(wt %) powders by conventional milling technique. Hot pressing was carried out to make specimens. The wear test were carried out with these two types of diamond impregnated specimens. It was demonstrated that Ti coating was effective in improving the ability of grit retention and thus enhanced the tribological performance of diamond tool.

Sunlight Collector System is a new way to make sunlight available to living things. It transmits sunlight through fiber optics to wherever is needs. It applies the artificial lighting, underground lighting, intelligent building, museum lighting, restoration-room to health etc. Cutting out most of the ultra-violet and intra-red radiation. In this paper, we measured the spectrum analysis of sunlight and Sunlight collector System's light. Also, we found out the distance to get visible light.
