The UCP is an authoritative compilation of the customs and practice of letters of credit observed by most of the participants in the transaction. It remains the most successful set of private rules for trade ever developed. First issued in 1933, the UCP has been through five revisions, the latest being the present UCP 500, which came into force in 1994. Since 1994, new developments in transport, insurance, electronic commerce and banking industry have spurred the current revision of the rules. The ICC Banking Commission approved UCP 600 on October 25, 2006 by a unanimous vote of 91 to 0. The revision, which will come into effect on July 1, 2007, incorporates a number of changes from UCP 500 as follows : UCP 600 has a leaner set of rules, with 39 articles rather than 49 articles of UCP 500; New sections on "definitions" and "interpretations" have been added to clarify the meaning of ambiguous terms; The phrase "reasonable time" for acceptance or refusal of documents has been replaced by a firm period of five banking days; UCP 600 allows for the discounting of deferred payment credits. However, UCP 600 has two main problems such as the inconsistency with insurance industry and the banking community-oriented rules. We have some months before the commencement of UCP 600. From today to the commencement of UCP 600, we should study the full contents of UCP 600 and the influences on the trade industry.

Objective : Euimunbogam(醫門寶鑑) is a synthetic medical book based on Dongeuibogam(東醫寶鑑), which was written by Myoung-Shin Zhu(周命新) in middle of Joseon era. And the book was published by Myoung-Seok Lee(李命錫) in 1918. This book has generally known as it's written in 1724 so far. But the life of Myoug-Shin Zhu is not well-known, and the year when Euimunbogam was compiled should be reconsidered. Method : We will find the historical records of Myoug-Shin Zhu through the close study of Joseon literatures. Result : Seungjeongwonilgi(承政院日記), Ilsungrock(日省錄), Taeuiwonseonsaengan(太醫院先生案), Yeolha diary(熱河日記), Yeonamgip(燕巖集), Euimunbogam show that Myoug-Shin Zhu was born in 1729 and he died in 1798. He worked as Ju-Bu(主簿) in HyeMinseo(惠民署) and Euiyakdongcham(醫藥同參) in Naeuiwon(內醫院). Conclusion : Myoug-Shin Zhu wrote Euimunbogam in 1784. And he was one of the famous physicians during the period between the king Young-Jo and Jung-Jo.

Biodiesel is a renewable and environmentally friendly liquid biofuel for transportation. Insect is considered as a new valuable biomass to convert into biodiesel. In particular, BSF(Black Soldier Fly) containing high fat is a renewable source of biodiesel. Biodiesel drived BSF has high concentration of saturated fatty acid methyl ester and low concentration of polyunsaturted fatty acid methyl ester which makes it potentially an ideal substrate for producing excellent quality biodiesel. Most of the fuel properties of BSF biodiesel were met the requirements of standard EN 14214. BSF have a higher lipid yield and biodiesel productivity as compared to microalgae and vegetable oils. This review paper includes the overall summary and compilation of the insect research conducted on biodiesel production and includes the BSF biodiesel properties.

In this paper the authors provide comparative evaluation of current research that used liquefaction and pyrolysis method for bio-oil production from various types of biomass. This paper review the resources of biomass, composition of biomass, properties of bio-oil from various biomass and also the utilizations of bio-oil in industry. The primary objective of this review article is to gather all recent data about production of bio-oil by using liquefaction and pyrolysis method and their yield and properties from different types of biomass from previous research. Shortage of fossil fuels as well as environmental concern has encouraged governments to focus on renewable energy resources. Biomass is regarded as an alternative to replace fossil fuels. There are several thermo-chemical conversion processes used to transform biomass into useful products, however in this review article the focus has been made on liquefaction and pyrolysis method because the liquid obtained which is known as bio-oil is the main interest in this review article. Bio-oil contains hundreds of chemical compound mainly phenol groups which make it suitable to be used as a replacement for fossil fuels.

Change detection using aerial and satellite images is one of the important research topics in photogrammetry and image interpretation. It is of particular importance especially in the fields of military, political and administrative affairs. When there is a need to detect changes in multi-temporal images, the most efficient methods for change detection and thresholds of change/no change area need to be chosen. Also, the images obtained from the various methods need to be analyzed. To do so, we need a system that can support our decision making process. Therefore, in this paper, we propose the Decision Support System for Change Detection. This system is composed of Data Base, Model Base and Graphic User Interface(GUI). Data base is a compilation of previous change detection results, and Model Base comprise of numerous operations. The data can be input and have the results of change detection analyzed by using GUI. In this paper, we will explain the entire operation of the system and demonstrate the level of its effectiveness.

In 2012, the NIBR started publishing the Journal of Species Research (JSR) as an international specialized journal of biological taxonomy focusing on taxonomic research. JSR Volume 5 Number 3, to be published in October 2016, has been planned as a 'Special Edition on New and Unrecorded Species of Invertebrates in Korea', and so it consists of the reports of 149 new and unrecorded invertebrate species (including protozoa) discovered in Korea. In future, the JSR should further accelerate the use of such methods to generate valid data for new species and effectively support the compilation of 'National List of Species of Korea'. In this way, it will contribute significantly to enrich for biodiversity in Korea.

Constructivism is defined in a variety of ways (e.g., constructivist research paradigm, sociological constructivism, and philosophical constructivism) and applied in vastly different contexts. Among the various usages and interpretations of constructivism, one is educational constructivism that embodies an epistemological view of knowledge and learning that is an alternative to naive empiricism or classical behaviorism. To represent the full range of stances taken by educational constructivists, three versions of educational constructivism were considered in this study: individual constructivism originating in the work of Piaget, the radical version of constructivism associated with von Glasersfeld, and the social constructivism of Vygotsky. I investigated preservice teachers' meaning construction about constructivist epistemology as they went through their preservice teacher education program using in-depth interviews. This preservice teacher education program employs constructivist aspects of teacher education and generates applications of constructivism to the practice of teaching. Features of preservice teachers' internalized meanings of educational constructivism include: (1)traditional pedagogy as the default, (2) Literal interpretation of constructivism, (3) Individual constructivism as conceptual change learning, (4) Radical constructivism as a strong individualistic philosophy, (5) Social constructivism as being too ideal to be practical. A compilation of the teachers' own statements about how to implement conceptual change learning and their projected role as constructivist teacher is also provided.

Epitaxial aluminum nitride films on 6H-SiC (0001) were fabricated using reactive RF magnetron sputtering and post-deposition rapid thermal annealing. The electrical properties of AIN films depending on film thickness and measurement temperature have been observed. Full width at half maximum of AIN (0002) was $0.1204^{\circ}$ (about 430 arcsec) X-ray rocking curve results. The equivalent oxide thickness (EOT) of AIN film was estimated as about 10 nm and the leakage current density was within the order of $10^{-8} 4/cm^2$. The dielectric constant of AIN film estimated from the accumulation region of C-V curve measured at $300^{\circ}C$ was 8.3. The dynamic dielectric constant was obtained as 5.1 from J vs. 1/T plots at the temperature ranging from R.T. to $300^{\circ}C$ From above, estimation temperature dependance of the electrical properties of Al/AIN/SiC MIS devices was affirmed and useful data compilation for the reliabilities of SiC MIS is expected.

Knowledge acquisition is the process that extracts the required knowledge from available sources, such as experts, textbooks and databases, for incorporation into a knowledge-based system. Knowledge acquisition is described as the first step in building expert systems and a major bottleneck in the efficient development and application of effective knowledge based expert systems. One cause of the problem is that the process of human reasoning we need to understand for knowledge-based system development is not available for direct observation. Moreover, the expertise of interest is typically not reportable due to the compilation of knowledge which results from extensive practice in a domain of problem solving activity. This is also a problem of modeling knowledge, which has been described as not a problem of accessing and translating what is known, but the familiar scientific and engineering problem of formalizing models for the first time. And this formalization process is especially difficult for knowledge engineers who are often faced with the difficult task of creating a knowledge model of a domain unfamiliar to them. In this paper, we propose an automated knowledge acquisition tool which is based on an implementation of the Inferential Modeling Technique. The Inferential Modeling Technique is derived from the Inferential Model which is a domain-independent categorization of knowledge types and inferences ［Chan 1992］. The model can serve as a template of the types of knowledge in a knowledge model of any domain.
