This study carried out to assess the quality of the information presented on the internet about nutrition specifically in the field of health functional food by monitoring with 10 panels from May, 2004 to October. Four hundred seven relevant websites were initially selected from a process using 5 search engines and the keywords ‘food’ and ‘nutrition’, and 404 sites actually met all inclusion criteria. Most of the sites evaluated 219 (54.20%) were commercial sites and then distributed noncommercial organization site 93 (23.0%), individual site 92(22.8%). Assessment quality indicator was carried out using the 17 necessary requisites, which has been developed to enable users and information providers to judge the quality of food and nutrition information. The mean score for quality grade was 11.07, five site out of a maximum score of 17 and two sites with the lowest total scores for the quality of food and nutrition information. Noncommercial organization site assessed achieved the highest score in accurate and useful informations to the public. Low ranked sites had the most inaccurate or misleading information, emphasizing only the positive aspects of the information, with little or no evidence. Many commercial sites used personal testimony as the most popular ‘proof’ for the effectiveness of product. This was anecdotal rather than scientific evidence based on which the objective validation was difficult to be made. Therefore, it can be challenging for both public and health professionals, to sort out useful information from a plethora of advertisements and promotions on the web sites. Our results suggest that nutrition professionals should talk about useful information of health, food and nutrition with public and help them find the best available information when using the internet.

The purpose of this study was to evaluate web-sites related to infant health at day-care centers. A total of 87 web-sites were ultimately selected through Internet search engines, and educare sites. The basis of assessment in which standards and items were amended for the assessment of health information in previously used, and purpose, content, pertinence, accuracy, confidence, utility, authority, interactivity and continuance was assessed. Though the total score were 32 point, mean score was relatively low, 20.39 point. The score of accuracy and authority was relatively low while that of confidence and interactivity was high. As a result, it was revealed that there were no specific infant health related web-site with reliability guaranteed. Therefore, there is a need to develop a web-site providing accurate health information for infant at day-care centers. It is expected that these results can be utilized as a data for developing reliable web-site related infant health.

The geographical distribution of the toxic blue-lined octopus (commonly known as the blue-ringed octopus), Hapalochlaena spp., around the East/Japan Sea was investigated. Observation records of the octopus were gathered using commercial search engines on the Internet. A questionnaire to complement and enhance the base data was conducted that targeted fishermen from areas where the octopus was most likely to occur, i.e., the southeast coast and islands of Korea in the East/Japan Sea. Overall, 32 observational records of the blue-lined octopus were found from Korea and Japan. In Korea, only one record, from 2003, was found on a website; none of the 240 fishermen who participated in the questionnaire reported seeing blue-lined octopus. However, a total of 31 observations of the blue-lined octopus from 2004 to July 2010 were found from 17 different regions in the East/Japan Sea and neighboring waters in Japan. Twenty-two cases were from coastal Honshu Island, and nine were from the west coast of Kyushu Island, Japan. The northern distributional boundary of the blue-lined octopus on the Japanese coast was off Fukui Prefecture around latitude $36^{\circ}$10' N. Our results indicate that the blue-lined octopus is distributed extensively along the Japanese coast, at a low frequency, in the East/Japan Sea.

WWW which is an applicable massive set of document on the Web is a thesaurus of various information for users. However, Search engines spend a lot of time to retrieve necessary information and to filter out unnecessary information for user. In this paper, we propose the EFAM(the Extended Fuzzy AHP Method) model to manage the Web resource efficiently, and to make a decision in the problem of specific domain definitely. The EFAM model is concerned with the emotion analysis based on the domain corpus information, and it composed with systematic common concept grids by the knowledge of multiple experts. Therefore, The proposed the EFAM model can extract the documents by considering on the emotion criteria in the semantic context that is extracted concept from the corpus of specific domain and confirms that our model provides more efficient decision-making through an experiment than the conventional methods such as AHP and Fuzzy AHP which describe as a hierarchical structure elements about decision-making based on the alternatives, evaluation criteria, subjective attribute weight and fuzzy relation between concept and object.

Web robot is an important Internet software technology used in a variety of Internet application software which includes search engines. As Internet continues to grow, implementations of high performance Web robots are urgently demanded. For this, researches specially geared toward performance scalability of Web robots are required. Hoover, because researches are focused mostly on addressing issues related to commercial implementations, scientific researches and studies are not still made on the performance scalability. In this research, Ive choose a Web robot model implemented by fork-join based. multiprocesses. With respect to the model, we evaluate the effect on the collection efficiency that the timeout values set to requests from Web robots to Web servers have. Also, we analysed the behaviors of Web robots by comparing the execution time between the URL extraction and the uniqueness checking for the extracted URLs. as well as by comparing between the computation time and the network time. Based on the analysis result, we suggest the direction for the design of high performance Web robots.

Transpiration cooling is the most effective cooling technique for liquid rocket and air-breathing engines operating in aggressive environments with higher pressures and temperatures. Combustor liners and turbine vanes are cooled by the coolant(air or fuel) passing through their porous walls and also the exit coolant acting as an insulating film. However, its practical implementation has been hampered by the limitations of available porous materials. The search for more practical methods of increasing the internal heat transfer within the walls has led to the development of multi-laminate porous structures, such as Lamilloy$^{(R)}$ and Transply$^{(R)}$. This paper reviews recent research activities of transpiration cooling for the propulsions of liquid rocket, gas turbine, and scramjet.
