This study was attempted to review the information data for minimizing the destruction of environmental naturalness and the visual damage of landscape from road construction by establishing a model of environmental naturalness for national roads in the suburb areas to suggest an answer to a research question, ' hat does decide the environmental naturalness of roadscape?'. We found that 1) The road-side slope showed no statistical significance in the description of environmental naturalness of roadscape, but the fact that the road-side slope from road construction is the destruction of natural topography cannot be overlooked. 2) In terms of the direction of value variations for independent variables, signboard and telegraph post, soundproofing and protection wall, structure, and building acted toward negative (-) direction, while mountains, sky, road trees, fields, and surrounding green including the road-side slope acted toward positive(+) direction. 3) The variable with highest relative contribution to dependent variables among independent variables is building, which has importance as many as 148 times of road-side slope, while the variable road-side slope has the least importance. Building has the importance of 7.22 times, mountains 5.51 times, road trees 2.59 times, surrounding green 2.54 times, structure 2.41 times, signboard and telegraph post 2.37 times, soundproofing and protection wall 2.20 times, and sky 1.32 times of the fields as a standard criterion values 1.

Backgrounds: The accident at Fukushima Daiichi Nuclear Power Plant (NPP), March 2011, caused serious radioactive contamination over wide area in east Japan. Therefore, it is important to know the effect of the accident and the status of NPP. Materials and Methods: This paper provides a review on the status of radiation dose and radioactive contamination caused by the accident on the basis of publicized information. Results and Discussion: Monitoring of radiation dose and exposure dose of residents has been conducted extensively by the governments and various organizations. The effective dose of general residents due to the accident proved to be less than a mSv both for external and internal dose. The equivalent committed dose of thyroid was evaluated to be a few mSv in mean value and less than 50 mSv even for children. Monitoring of radioactivity concentration has been carried out on food ingredients, milk and tap water, and actual meal. These studies indicated the percentage of foods above the regulation standard was over 10% in 2011 but decreasing steadily with time. The internal dose due to foods proved to be tens of ${\mu}Sv$ and much less than that due to natural $^{40}K$ even in the Fukushima area and decreasing steadily, although high level concentration is still observed in wild plants, wild mushrooms, animals and some kind of fishes. Conclusion: According to extensive studies, not only the effect of the accident but also the pathway and countermeasures against radioactive contamination have been revealed, and they are applied very effectively for restoration of environment and reconstruction of the area.

Many new functional materials have been studied for efficient production and storage of energy. Many new materials such as sodium-based and sulfide-based materials have been proposed for energy storage, but research on Li batteries is still dominant. Due to the influence of environmental concerns regarding nuclear energy, interest in and research on fusion power are steadily increasing. For the commercialization of nuclear fusion, a design standard based on a considerable level of physical analysis and modeling is proposed. Nevertheless, limitations of existing materials in nuclear fusion environments limit practical applications. Tritium propagation material for continuous fusion reaction is one of the core materials, and therefore research on this material is being carried out intermittently. The key material for Li-based energy storage and tritium generation is the functional material Li-M-O. In this review, a structural description of functional Li-M-O system materials and technical trends for its applications are introduced.

Licensing of information is the standard of the computer information business today. The huge bulk of vendors license their computer information products. The Uniform Computer Information Transactions Act(UCITA), therefore, does not originate licensing contracts. UCITA was developed to provide basic, recognizable default rules for the existing licensing activity that goes on and expands as commerce in computer information expands. UCITA's rules govern licensing of contracts for computer information from formation through performance, including remedies if there is a breach of contract. Included in UCITA are rules for warranties, both implied and express, and rules pertaining to risk of loss in a computer information transaction. Most of the rules in UCITA are the traditional and familiar rules of contract from the law of sales and from the common law, but adapted to the special nature of computer information licensing contracts. Freedom of contract is a dominating underlying policy for UCITA, exactly as that principle is the foundation for the law of commercial transactions, generally, and exactly as that law has served all commercial transactions in the United States and has contributed to the economic growth and health of the United States.

Objectives The purpose of this study was to survey the status of clinical use of a computerized tongue diagnosis system (CTDS) Methods We searched domestic/international articles using the CTDS from online medical databases including OASIS, NDSL and pubmed. We selected articles on clinical application or reliability of CTDS but excluded articles on mechanical design or software programming for developing a new CTDS. Finally we found 15 articles and classified the articles according to the study purpose. Results Out of the 15 articles, 8 were focused on the clinical application including halitosis, cold/heat syndrome, lung cancer, xerostomia etc. Other 5 articles were aimed at evaluating and improving reliability of CTDS. The other 2 articles were studied for development of differential diagnostic criteria on tongue coating thickness. Conclusion We found out that until now the researches on clinical application of CTDS mainly had been performed for producing a variety of CTDSs. Considering the importance of the tongue color in the traditional Korean medicine, we suggest that at first standard operating procedure for CTDS be developed and researches to develop differential diagnostic criteria on tongue body/coating color be performed and then explore its applications.

Metagenomics has become one of the indispensable tools in microbial ecology for the last few decades, and a new revolution in metagenomic studies is now about to begin, with the help of recent advances of sequencing techniques. The massive data production and substantial cost reduction in next-generation sequencing have led to the rapid growth of metagenomic research both quantitatively and qualitatively. It is evident that metagenomics will be a standard tool for studying the diversity and function of microbes in the near future, as fingerprinting methods did previously. As the speed of data accumulation is accelerating, bioinformatic tools and associated databases for handling those datasets have become more urgent and necessary. To facilitate the bioinformatics analysis of metagenomic data, we review some recent tools and databases that are used widely in this field and give insights into the current challenges and future of metagenomics from a bioinformatics perspective.
