Catastrophic events cause casualties, damage property, and lead to huge social impacts. To build common standards and facilitate international communications regarding disasters, the relevant authorities in social management rank them in subjectively imposed terms such as direct economic losses and loss of life. Terrorist attacks involving uncertain human factors, which are roughly graded based on the rule of property damage, are even more difficult to interpret and assess. In this paper, we collected 114 183 open-source records of terrorist attacks and used a machine learning method to grade them synthetically in an automatic and objective way. No subjective claims or personal preferences were involved in the grading, and each derived common factor contains the comprehensive and rich information of many variables. Our work presents a new automatic ranking approach and is suitable for a broad range of gradation problems. Furthermore, we can use this model to grade all such attacks globally and visualize them to provide new insights.

Of the Asp. spp. isolated by the Institute of Applied Microbiology, Kon-Kuk University, 7 strains were selected for the study of the immunological differencences among them using gel precipitation test. The strains were the following types : 1 type of flavus and 2 types of oryzae were isolated from Meju ; 1 type of flavus from Nuruk ; and each one type of flavus, parasiticus and oryzae from Kokja.Asp.flavus from ATCC, Asp. parasiticus nad Asp. niger NRRL strains were also used in the study as a standard. From this study, several points can be raised ; 1) There was no common antigenic property between Asp. niger and Asp. flavus, because of no formation of reaction line. Therefore, all strains could be easily distinguished. 2) There was common antigenic property, that is, the formation of reaction line between Asp. flavus and Asp. parasticus. Accordingly two strains could not be easily distinguished by the gel precipitation test. 3) Each type of oryzae, parasiticus and flavus of Asp. flavus group had common antigen one another as well as specific antigens only in the difference of the reaction lines, so they could be easily identified in the gel precipitation test. 4) Each isolated strain from Meju and Nuruk appeared to be identical. 5) It was shown that the gel precipitation test of serological methods was very useful for the classification of Asp. spp.

Since a declaration between North and South Korea was adopted, North and South Korea has strengthened the interchange and cooperation between each other in many fields. Especially, the interchange and cooperation in the field of industrial property right, such as patent and trademark, are required to keep up with the age of the knowledge industry. But, until a recent date, there has been little interchange or cooperation in the field of industrial property right, and a few major companies were attempt to apply for the patent in North Korea through the Third country The system of industrial property laws in North and South Korea are very different because of time and political ideology barriers. To unify the system of industrial property laws in North and South Korea, firstly, North and South Korea must try to recognize and understand the dissimilarity between them. In this article, I compared the system of industrial property law of South Korea with that of North Korea to search commonalities and dissimilarities. Furthermore, it is needed to establish systematic devices for understanding of between North and South Korea, for instance, conducting a interdisciplinary seminar or dispatching a judge mutually. Finally, it is necessary to phase in a practical plan for unification. In the short run, mutual application and registration have to be authorized, and in the long view, unifying the practice of industrial property law service is needed. At the conclusion, the industrial property laws in North and South Korea can be unified systematically. In other words , to unify system of industrial property laws in North and South Korea, it is prerequisite that mutual understanding of industrial property laws and performance of the unify plan. The interchange and cooperation in this field will not only promote technical development but also create common interests of North and South Korea by expanding an opportunity for creating and utilizing industrial property.

A brief comparative survey of some generalizations of a metric space with three dimensional metric structures and different forms of the triangle inequality is done along with their topological properties. Then a common fixed point is obtained for reciprocally continuous and compatible self-maps in a G-metric space. Further, a common fixed point theorem is proved for a pair of weakly compatible self-maps on a G-metric space with the common limit range property.

Let X and Y be independent identically distributed nondegenerate random variables with common absolutely continuous probability distribution function F(x) and the corresponding probability density function f(x) and $E(X^2)$<${\infty}$. Put Z = max(X, Y) and W = min(X, Y). In this paper, it is proved that Z - W and Z + W or$(X-Y)^2$ and X + Y are independent if and only if X and Y have normal distribution.

The purpose of this study aims to the improvement prospect of green insurance industry in Korea. Green insurance includes all classes of general insurance business including unoccupied property insurance and empty building insurance, business insurance, personal insurance, etc. Green policies often cover expensive systems that are not covered under most property policies. The same is true for some underground property, which is also exempted from many property policies. At least insurers already offer products designed to fund rebuilding damaged properties to meet certain environmental and building standards. While the products are in their infancy, insurers and brokers say the huge interest in environmental issues will increase demand. Green buildings that improve energy efficiency and air quality and reduce waste are designed to reduce their effects on the environment and the health of building occupants. Buildings account for 39% of U.S. carbon dioxide emissions, according to the Department of Energy. Insurers say that, as sustainable buildings become more common, green insurance will become more popular and some of its features might become a standard part of property policies.

Radioactive wastes arising from a wide range of human activities are in many different physical and chemical forms, contaminated with varying radioactivity. Their common feature is the potential hazard associated with their radioactivity and the need to manage them in such a way as to protect the human environment. The geological disposal is regarded as the most reasonable and effective way to safely disposal high-level radioactive wastes in the world. The conceptual model of geological disposal in China is based on a multi-barrier system that combines an isolating geological environment with an engineered barrier system. The buffer is one of the main engineered barriers for HLW repository. The buffer material is expected to maintain its low water permeability, self-sealing property, radio nuclides adsorption and retardation property, thermal conductivity, chemical buffering property, overpack supporting property, stress buffering property over a long period of time. Benotite is selected as the main content of buffer material that can satisfy above. GMZ deposit is selected as the candidate supplier for Chinese buffer material of High Level Radioactive waste repository. This paper presents geological features of GMZ deposit and basic property of GMZ Na bentonite. GMZ bentonite deposit is a super large scale deposits with high content of Montmorillonite (about $75\%$) and GMZ-l, which is Na-bentonite produced from GMZ deposit is selected as reference material for Chinese buffer material study.

This article chronicles key shifts in intellectual property regimes in the twentieth century as they related to the commercialization of academic research. The institutionalization and growth of scientific research in the research university in the twentieth century and the increasing awareness of its potential to promote technology innovation and economic growth posited an important question of the ownership of knowledge created in the academic setting, where knowledge was traditionally regarded as a common property among academic researchers. This paper shows the ownership of academic knowledge emerged as a key public policy and legal issue in the latter half of the twentieth century for academic researchers and government officials who pursue the commercialization of academic knowledge for private gain and public benefit. The resulting institutionalization of patent management in the research university and shifts in federal patent policy in turn opened a new legal avenue for the establishment of the private ownership of academic knowledge and the expansion of intellectual property rights in academia, especially in the area of biological and biomedical research. Reflecting upon historical shifts in intellectual property regimes in the twentieth century, this paper suggests recent controversies regarding ownership of biological knowledge and profit sharing in developing counties are linked to critical issues pertinent to the welfare of indigenous population, utilization of new natural resources, and sustainable development for humanity.
