  • Cooperation between government agencies is important for disaster management, and a thorough and objective cause investigation is important to prevent the recurrence of similar disasters. In South Korea, individual laws are scattered by ministries according to the disaster type, and most are operated as non-permanent organizations that are employed when disasters occur. Although expertise is recognized for each disaster type, each government agency's operation method is different, so when a large-scale disaster involving multiple ministries occurs, there is a limit to the coordination of roles and integrated management between government agencies. In particular, whenever a large-scale complex disaster occurs, problems arise regarding the independence, professionalism, and fairness of the cause investigation. Therefore, to supplement this, reviewing the management methods and systems of disaster cause investigations in advanced countries is necessary. Thus, in this study, the organization status, manpower, organizational structure, and cause investigation work system of NTSB of the United States, JTSB of Japan, and SHK of Sweden are identified to improve the disaster cause investigation system in Korea and are compared and analyzed with Korea's GDCIG. Additionally, issues and problems for the advancement of Korea's disaster cause investigation system are considered and improvements are suggested.

  • The purpose of the study is to find out students' misconceptions and the stability of misconceptions in the domain of mechanics. According to the incorrect choices by grades, three different kinds of conceptual change were identified ; (1) easily overcome misconceptions, (2) stable misconceptions, and (3) reinforced misconceptions. The analyses of the results showed that easily overcome misconceptions occurred in simple or visual concepts, stable misconceptions occurred in the concepts involving EGC(experiential gestalt of causation) or in the concepts overgeneralized in school teaming, and finally, reinforced misconceptions as grade level increases occurred in the concepts EGC with scientific logical procedures. The results on the type of conceptual changes may provide significant cognitive theoretic evidences on the sources of misconceptions.

  • This paper is comparing numerical schemes for a differential equation with convection and fourth-order diffusion. Our model equation is $h_t+(h^2-h^3)_x=-(h^3h_{xxx})_x$, which arises in the context of thin film flow driven the competing effects of an induced surface tension gradient and gravity. These films arise in thin coating flows and are of great technical and scientific interest. Here we focus on the several numerical methods to apply the model equation and the comparison and analysis of the numerical results. The convection terms are treated with well known WENO methods and the diffusion term is treated implicitly. The diffusion and convection schemes are combined using a fractional step-splitting method.

  • In the Joseon dynasty one in seven houses enjoyed their home-brewed alcoholic beverages, which lead to the development of a variety of Korean traditional liquors throughout the country. However, when Korea was under Japanese rule, Korean traditional alcoholic beverages disappeared during this period. Since the 1980s, the Korean government has tried to revitalize the traditional alcoholic drinks unique to Korean culture and taste. Nevertheless, the development of traditional liquors is subjected to many constraints due to current market demand and liquor laws. To address this, we propose some suggestions that should be implemented ahead. First, it is necessary to revise the term traditional liquor including makgeolli as 'Korean sool' to expand the market size. Secondly, the use of koji and excellent yeast isolated from nuruk should be scientifically modernized. Lastly, the government should establish the National Korean Sool Research Institute. These practices will contribute to the succession of Korean liquor and its globalization.

  • The purpose of this study is to explore the philosophical position of various scientific theories based on the scientific worldviews for science education. In addition, it aims to expand science education, which has usually dealt with epistemology and methodology, to ontology, that is, to the problem of metaphysics. It can be said that there exists a physical realism, traditionally defined as a strong determinism of the metaphysical belief. That is fixed and unchanging objective scientific knowledge independent of our minds, which was established by Newton, Einstein and Schridinger. What can be seen in the natural laws of dynamics can be called 'mathematicization'. Einstein also shook the traditional views to some extent through the theory of relativity, but his theory was still close to traditional thinking. On the contrary, to escape from this rigid determinism, we need anthropomorphic concepts such as 'possibility' and 'chance'. It is a characteristic of the modern scientific worldviews that leads the change of scientific theory from a classically strong deterministic thought to a weak deterministic accidental accident, probability theory, and a naturalistic point of view. This can be said to correspond to Darwin's theory of evolution and quantum mechanics. We can have three types of epistemological worlds that justify this ontological worldviews. These are rationalism, empiricism and naturalism. In many cases, science education does not tell us what kind of metaphysical beliefs the scientific theories we deal with in the field of education are based on. Also, science education focuses only on the understanding of scientific knowledge. However, it can be said that true knowledge can bring understanding only when it is connected to the knowledge of learned knowledge and the learner's own metaphysical belief in the world. Therefore, in the future, science education needs to connect various scientific theories based on scientific worldviews and philosophical position and present them to students.

  • As there has been growing interests in PHR-based personalized health management project, various institutions recently explore safe methods of recording personal medical and health information. In particular, innovative medical solution can be realized when medical researchers and medical service institutes can generally get access to patient data. As EMR data is extremely sensitive, there has been no progress in clinical information exchange. Moreover, patients cannot get access to their own health data and exchange it with researchers or service institutions. It can be operated in terms of technology, yet policy environment are affected by state laws as well as Privacy and Security Policy. Blockchain technology-independent, in transaction, and under test-is introduced in the medical industry in order to settle these problems. In other words, medical organizations can grant preliminary approval on patient information exchange by using the safely encrypted and distributed Blockchain ledger and can be managed independently and completely by individuals. More apparently, medical researchers can gain access to information, thereby contributing to the scientific advance in rare diseases or minor groups in the world. In this paper, we focused on how to manage personal medical information and its protective use and proposes medical treatment exchange system for patients based on a permissioned Blockchain network for the safe PHR operation. Trusted Model for Sharing Medical Data (TMSMD), that is proposed model, is based on exchanging information as patients rely on hospitals as well as among hospitals. And introduce medical treatment exchange system for patients based on a permissioned Blockchain network. This system is a model that encrypts and records patients' medical information by using this permissioned Blockchain and further enhances the security due to its restricted counterfeit. This provides service to share medical information uploaded on the permissioned Blockchain to approved users through role-based access control. In addition, this paper presents methods with smart contracts if medical institutions request patient information complying with domestic laws by using the distributed Blockchain ledger and eventually granting preliminary approval for sharing information. This service will provide an independent information transaction and the Blockchain technology under test will be adopted in the medical industry.

  • This study discusses the definition, determination and use of Imminent & Substantial Endangerment (ISE) included in the United States environmental laws. ISE is a contamination situation and statutory authority that state and federal governments issue an administrative order to responsible parties for clean-up. ISE is appeared in all kinds of official government documents such as administrative oders on consent, judicial consent degrees, and unilateral administrative order. In order to invoke ISE authority, the governments should have evidence of each of the following elements; 1) a possible ISE 2) because of actual or threatened release 3) of a hazardous substance 4) from a facility. The determination of ISE relies on detail scientific evidence and documentation in order to demonstrate the existence of conditions that may present an ISE. However, any official protocol or procedure has not been found for determining an ISE, although an ISE order documentation format is suggested by U.S. EPA.
