This study examined the stakeholder cognition of the safety certification marking system by surveying manufacturers, lessors, and users. In addition, among various issues about safety certification marking systems, the improvement of safety certification marking contents was suggested in order to guarantee quality of temporary equipments. The results by statistical method show that it is necessary to increase of users' understanding about the safety certification marking system. In addition, the quality management system of temporary equipments should be introduced to control the actual condition that temporary equipments of various product companies are mixed in a site during removal and reuse processes. For detailed marking contents, it is recommended that a certification mark, an identification number, and the production year should be displayed and the manufacturer name could be selectively presented. Detail informations such as a safety certification number, a product company, a model type or name, a specification, a weight, a product number, and the location of a certification mark should be identified by the identification number.

Augmented reality based on projection, called "Spatial Augmented Reality (SAR)", is a new technology that can produce immersive contents by overlapping virtuality and real-world environment. It has been paid attention as the next generation digital contents in media art and human-computer interaction (HCI). In this paper, we present a new methodology to evaluate the product appearance design more intuitively by means of SAR technique. The proposed method first projects the high-quality rendered image considering the optical property of materials onto the mock-up of a product. We also conduct a projector-camera calibration to compensate a color distortion according to a projector, a projection surface and environment lighting. The design evaluation methodology we propose offers more flexible and intuitive evaluation environment to a designer and user (evaluator) than previous methods that are performed via a digital display. At the end of this research, we have conducted a case study for designing and evaluating appearance design of an automobile.

This study was carried out to investigate the effect of diet (1:1 ratio) added with meat product (seasoning chicken product, patty) containing natural extracts (green tea, Schizandra chinensis) on body weights, internal organs weights, the contents of total cholesterol, HDL-cholesterol, triglyceride and total lipid in plasma and liver. The experimental diets were prepared with basal diet added with $1\%$ natural extracts. These diets were supplied to SD (Sprague-Dawley) rats for 45 days. The body weight of SD rats supplied seasoning chicken and patty containing green tea and Schizandra chinensis tended to be lower than that of SD rats dieted seasoning chicken product and patty product. The contents of plasma cholesterol, HDL-cholesterol, triglyceride and total lipid were decreased in SD rats dieted seasoning chicken and patty with green tea and Schizandra chinensis. However, the contents of plasma cholesterol, HDL-cholesterol, triglyceride and total lipid tended to be increased in SD rats supplied seasoning chicken product and patty only. Hepatic lipid peroxidation measured by TBARS method was not different, compared to that of control. In conclusion, the diets with meat products containing $1\%$ natural extracts were effective in reducing plasma and hepatic cholesterol levels in rats.

The specifications which are drawn up when developing a software cannot achieve continuous automation because of individual qualities of them, and many inconsistent elements can be discovered even from software audit. In this paper, we establish the standards for the classification of inconsistent items by analysing audit related data in order to maintain the consistency among specifications drawn up in the phases of analysis and design. We propose the specification inconsistent item detection method. This can reduce the error of the specification which is drawn up from analysis and design phase with it will be able to improve the quality of the software which is a last product. It can improve the quality of the software which is a last product, by reducing the error of the specification which is drawn up from analysis and design phase.

The question answering system shows the answers that are input by other users for user's question. In spite of many researches to try to enhance the satisfaction level of answers for user question, there is a essential limitation. So, the question answering system provides users with the method of recommendation of another questions that can satisfy user's intention with high probability as an auxiliary function. The method using the fuzzy relational product operator was proposed for recommending the questions that can includes largely the contents of the user's question. The fuzzy relational product operator is composed of the Kleene-Dienes operator to measure the implication degree by contents between two questions. However, Kleene-Dienes operator is not fit to be the right operator for finding a question answers pair that semantically includes a user question, because it was not designed for the purpose of finding the degree of semantic inclusion between two documents. We present a novel fuzzy implication operator that is designed for the purpose of finding question answer pairs by considering implication relation. The new operator calculates a degree that the question semantically implies the other question. We show the experimental results that the probability that users are satisfied with the searched results is increased when the proposed operator is used for recommending of question answering system.

The objective of this study was to develop the classification method of various organic wastes. Specifically, the effects of proximate composition on the biogas production and degradation rates of agricultural by-production was investigated and a new standards for mixture of various organic wastes based on proximate composition combination was developed. Agricultural by-products (ABPs) with medium total carbohydrate, medium crude protein and low fat contents demonstrated the single step digestion process. ABPs with low total carbohydrate, high crude protein and high fat contents demonstrated the two step digestion process of Diauxic growth. The single ABP (Class No. 15) and the mixed ABPs (Class No. 12+18, 6+12+22, 9+12+18) after 10days showed the similar biogas yield pattern. We can use the classification method for the more ABPs and organic wastes from factory and municipal waste treatment plant for the high efficient biogas production.
