This study was performed to compare the physiological effects of puffed snack on diabetic and geriatric diseases using miscellaneous cereals and grain crops. The puffed snacks were prepared with different amounts of miscellaneous cereals and grain crops (in ratios of 10%, 20%, and 30% of brown rice). Changes in the water soluble index, water absorption index, color, antioxidant activity, total polyphenol content acidity, ${\alpha}$-glucosidase inhibition activity, and sensory evaluation were also determined. As the cereal and crop contents increased, the value of the water soluble index increased while the water absorption index decreased, with the exception of glutinous foxtail and barnyard millets. With respect to color, lightness and yellowness decreased in concert with increases in the cereal and crop contents, whereas redness increased. Furthermore, the antioxidant activity and total polyphenol content as well as ${\alpha}$-glucosidase inhibition activity increased remarkably with increasing concentrations of sorghum. There was no significant difference in the physiological activities depending on the addition of millet, barley and barnyard millets. In sensory evaluation, the puffed snacks containing sorghum, millet, and glutinous foxtail millet received higher values than other samples. Altogether, our results indicate that puffed snacks containing 10~20% sorghum could be suitable as ingredients for improving sensory and physiological activities in diabetic and geriatric diseases.

The rapid progress of the intermodal freight transportation in recent years has induced fierce competition among the adjacent hub ports for container transport. This brings increased attention to the evaluation of the port competitive ability. But it is not easy to evaluate the port competitive ability because this belongs to ill-defined system which is composed of ambiguous interacting attributes. Paying attention to this point, this paper deals the competitive ability of container port in Far-East Asia by fuzzy integral evaluation which is adequate to interacting ambiguous attribute problem. For this, the proposed fuzzy evaluation algorithm is applied to the real problem, based on the factors such as cargo volumes, costs, services, infrastructure and geographical sites These are extracted from the precedent study of port competitive ability, etc. The results show that the port evaluation factors come in following order ; services, costs, infrastructure, geographical sites and cargo volumes. There are some interactions(interaction coefficient, ${\lambda}=-0.664$ between evaluation attributes. The port competitive ability comes in following order : Singapore, Hongkong, Kobe, Kaoshiung and Busan. According to the sensitivity analysis, the rank between Busan and Kaoshiung changes when ${\lambda}=0.7$. From the analysis of the results, we confirmed that the proposed fuzzy evaluation algorithm is very effective in the complex-fuzzy problem which is composed of hierarchical structure with interacting attributes.

It is important issue how to evaluate the economic feasibility of computing factors in the real world when we build ubiquitous spaces. In this paper, we propose a simple model that can evaluate the economic feasibility of mobile RFID-based ubiquitous computing system which enables seamless communication between offline and online via embedded computing factors in the real world. To achieve this, we explore the meaning of mobile RFID system, the difference between our research and extant researches concerning the evaluation of economic feasibility in RFID system, and propose the so-called 'Tag-based Evaluation Model' (TEM) which is an evaluation model to access the economic feasibility of mobile RFID systems. We also analyze the TEM via simulation cases based on proposed model and discuss the future of TEM.

The wide spread of the Internet has become a momentum to promote informatization, and thus individuals, organizations, and government bodies are competitively participating in this kind of new wave. Informatization enables us not only to circulate and utilize information without any limitation but also to maximize users' benefits and convenience. On the other hand, it brings about negative effects-security incidents such as cyber terror, Internet fraud and technology leakage, etc. Evaluation on security level should precede over all the others in order to minimize damage by security incidents since it diagnoses current status on security as it is and can be used as a guideline for appropriate security management. In this study, evaluation domains, items and indicators of information security to evaluate information security are theoretically developed on the basis of critically reviewing the major existing research. And then the coincidence level(content validity, ease and reliability of evaluation) of each evaluation indicators are empirically analyzed through performing the field study of 83 information security experts.

This study aims to propose a framework for evaluating the impact of artificial intelligence (AI) services, based on the concept of AI service impact. It also suggests a model for evaluating this impact and identifies relevant factors and measurement approaches for each item of the model. The study classifies the impact of AI services into five categories: ethics, safety and reliability, compliance, user rights, and environmental friendliness. It discusses these five categories from a broad perspective and provides 21 detailed factors for evaluating each category. In terms of ethics, the study introduces three additional factors-accessibility, openness, and fairness-to the ten items initially developed by KISDI. In the safety and reliability category, the study excludes factors such as dependability, policy, compliance, and awareness improvement as they can be better addressed from a technical perspective. The compliance category includes factors such as human rights protection, privacy protection, non-infringement, publicness, accountability, safety, transparency, policy compliance, and explainability.For the user rights category, the study excludes factors such as publicness, data management, policy compliance, awareness improvement, recoverability, openness, and accuracy. The environmental friendliness category encompasses diversity, publicness, dependability, transparency, awareness improvement, recoverability, and openness.This study lays the foundation for further related research and contributes to the establishment of relevant policies by establishing a model for evaluating the impact of AI services. Future research is required to assess the validity of the developed indicators and provide specific evaluation items for practical use, based on expert evaluations.
