The object that we have researched the design for a long life of product is to search for the method to cope with the various environment problems where our mankind is confronting in the field of Production Design. The environment problem on earth is affecting seriously the enterprise which produces the product, the user who consumes it and even the field of product design. Now we live our daily life with a lot of artifacts while the citification and modernization have been progressing around us. Especially, 20 century was the times of the highly advanced scientific civilization and industrialization. Therefore it affected decisively our life environment base nowadays. The result was that our human life became rich because of the advanced development of industry, productivity and distribution structure. On the other side, the industrial system in the period of these massive production and massive consuming is bearing various problems proportionally. Those are the depletion of resources and energy, earth environmental pollution and various kinds of waste. In addition, the material which cannot recycle is appearing at the large quantity. This is the actuality of now. Our subject is how product design will cope with it as counter measures and the subject is very important to our mankind and earth environment.

Fuzzy Controller is a system that displays a person's thoughts using membership function and IF-THEN rules. With the help of specialists' knowledge, rule bases can be explained in easy language. Furthermore Fuzzy Controller has strong resistance against turbulence. Its performance is especially prominent when targets cannot be measured in mathematic methods because the fuzzy controller can measure the output using only the relations between the input and output. With the increasing influence of multimedia on our daily lives, vision plays bigger role both in industries and personal lives. Like wise vision is being used in many areas such as detecting and identifying objects. It is difficult to detect and control targets because there is a delay in the calculating when using vision in detecting and controlling objects in large quantity. In this paper we showed how to use fuzzy controller in minimizing the calculation process, controlling target objects and moving view window instead of applying input variation through vision. Ball beam, which has strong nonlinear, was used as the target object and DSP320C6711 IDK by TI(Texas Instruments) company was for the benefit of speedy calculation and vision data operation.

In this study, I investigate the literary features and educational values of spoken travelogues by analyzing a travelogue about the Diamond Mountains by a farmer named Im, Chul-ho, a very interesting travelogue told for 70 minutes. It seems to have educational significance as a wonderful piece of literary work. The literary features of this tale can be summarized as follows. (1) It is truly 'literature of reality' which fully brings out literary appreciation; It evokes interest and emotional tension on the part of audience through vivid verbal embodiment of personal experiences; (2) It is a well constructed big story embedding small stories within it. The stories from many different travel points emerge into a whole unified story making it much richer and more attractive; and (3) It truly reflects the experiences and emotions of ordinary people. As such, it can be regarded as their spiritual property. In addition, spoken travelogues could be valuable as an object in literature education. It needs to be included in the literature curriculum and treated in the same way as written travelogues. With strengths as instructional materials, it could be effectively used to improve students' ability to express their daily experiences with literary sensibility and to make them better understand the lives of ordinary people in the past.

This paper presents a multiple DoFs (degrees-of-freedom) prosthetic forearm and sEMG (surface electromyogram) pattern recognition and motion intent classification of forearm amputee. The developed prosthetic forearm has 9 DoFs hand and single-DoF wrist, and the socket is designed considering wearability. In addition, the pattern recognition based on sEMG is proposed for prosthetic control. Several experiments were conducted to substantiate the performance of the prosthetic forearm. First, the developed prosthetic forearm could perform various motions required for activity of daily living of forearm amputee. It was able to control according to shape and size of the object. Additionally, the amputee was able to perform 'tying up shoe' using the prosthetic forearm. Secondly, pattern recognition and classification experiments using the sEMG signals were performed to find out whether it could classify the motions according to the user's intents. For this purpose, sEMG signals were applied to the multilayer perceptron (MLP) for training and testing. As a result, overall classification accuracy arrived at 99.6% for all participants, and all the postures showed more than 97% accuracy.

The effect of improving awareness by educational programs for improving the quality of daily life of the disabled and safety depends on the type of disability and individual differences, as well as the difficulty in evaluating education achievement and satisfaction. However, more effective programs can be developed and provided if the factors affecting the effectiveness of education can be identified. Training as one of the factors affecting effectiveness involves motivation. This is thought to be an important factor for any object regardless of the type of disability. It is recognized that "By providing programs for the disabled to immerse themselves, they can be motivated to participate in education and expect greater effects on educational effects." Gamification is convincing enough for general learning. Furthermore, a feature of gamification is the use of the game's structure to achieve its goal, which acts on participants' motivation. Some use game packages such as analog games and digital games, but some include gamification of activities themselves. The use of gamification in education has different characteristics from the development of businesses. Therefore, in this paper, we reviewed the current status and challenges with the aim of promoting the use of gamification in life safety education for the disabled.

As the use of robots in service area increases, research has been conducted to replace human tasks in daily life with robots. Among them, this study focuses on the tidy-up task on a desk using a robot arm. The order in which tidy-up motions are carried out has a great impact on the success rate of the task. Therefore, in this study, a neural network-based method for determining the priority of the tidy-up motions from the input image is proposed. Reinforcement learning, which shows good performance in the sequential decision-making process, is used to train such a task planner. The training process is conducted in a virtual tidy-up environment that is configured the same as the actual tidy-up environment. To transfer the learning results in the virtual environment to the actual environment, the input image is preprocessed into a segmented image. In addition, the use of a neural network that excludes unnecessary tidy-up motions from the priority during the tidy-up operation increases the success rate of the task planner. Experiments were conducted in the real world to verify the proposed task planning method.

The object of this study was to develop the control technology of daily integral photosynthetic photon flux (PPF) by the artificial lighting and shading screen in greenhouse. The shading time needed to get the target PPF by using two types of shading screens having shading ratio of 55% and 85% was analyzed. The results showed the shading ratio of screen to be installed in greenhouse should be different depending on the amount of target PPF to be controlled. The PPF control experiment by using the 55% shading screen in July and August showed that the maximum difference between measured and calculated value was about 5 mol$.$ $m^{-2}$ $.$ $d^{-1}$ in no shading condition. This difference is satisfactory result because the daily integral PPF is quite different depending on the weather condition. The simulation result about PPF distribution pattern shortened the time needed to find the proper arrangement of artificial lightings in greenhouse. But the further study was required to find the supplemental lighting arrangement to be able to provide the exactly uniform distribution of target light intensity. The supplemental irradiation time needed to acquire the target daily integral PPF for different supplemental light intensities, weather conditions, and months was analyzed. The result showed that the supplemental light intensity should be decided depending on the amount of target PPF to be controlled. The result of PPF control experiment conducted by using 55% shading screen and 300 $\mu$mol$.$ $m^{-2}$ $.$ $s^{-1}$ supplemental light intensity from the end of May to the beginning of June showed that the maximum difference between target and measured value was about 3 mol$.$ $d^{-1}$ $.$ $m^{-2}$ . If we consider that the difference of the daily integral PPF depending on weather condition was the maximum 30 mol$.$ $m^{-2}$ $.$ $d^{-l}$, the control effect was acceptable. Although the result of this study was the PPF control technology to grow lettuce, the data and control method obtained could be employed for other crop production.n.

The purpose of this study is to propose a health improvement education program for the majority of elderly people who could not work due to health issues. This study focused on the fact that employment has a positive influence on the health outcomes of the elderly. The paper compares the health outcomes of employed elderly versus that of the unemployed, and suggests directions for future lifelong education programs related to health for the unemployed elders. The study results show more positive health outcomes for employed elders in terms of nutrition status and ability to perform daily tasks. Furthermore, their cognitive ability was more active (orientation, peripheral concentration, awareness of daily life) and their overall quality of life. Therefore, the study aims to develop health outcomes in the unemployed elderly population through safety education, improving health habits, performance improvement education via cognitive activation and socializing, and to secure the professionalism of lifelong education programs for the elderly which is currently only seen as a leisure activity. The object of the proposed program in this study is to maintain health by providing opportunities employment - a core component of successful aging - and relevant social interaction. This will greatly improve the quality of life of the elderly and provide a basis for widening the social role of elderly people in the future.
