The denuclearization of North Korea was unpredictable and resulted in radical changes. Despite the skepticism and disappointment surrounding denuclearization, it is important for certain verification technologies to establish what is technically possible or practically impossible, and how reliable these technical means are. This article presents the technical hurdles in nuclear verification by systematically categorizing them into issues of correctness and completeness. Moreover, it addresses the safety and security risks during the denuclearization process, including the radiological impact on humans, environmental effects, and the illegal transfer of material, information, and technologies.

This study is an empirical study approach to investigating impact of 3D stereoscopic film's customer satisfaction. Using conventional methods, there were identified 3D stereo films's factors that character, story, dialogue, music, and 3D technical factors. And There were trying to analyze the impactive gaps of 3D stereoscopic film's customer satisfaction between high participation and low participation of customers about 3D film's. The results of this study can be summarized broadly as follows. First, the story and 3D technical factors was high-impact of customer's satisfaction at watching the 3D films. Second, 3D technical factors were highly correlated with customer satisfaction at the low participation group. And 3D technical factors and story were highly correlated with customer satisfaction at the high participation group. The conclusion is expected to provide useful suggestions about the selection of variables at the future 3D film study.

The amount of non-lignin components in unbleached and oxygen-delignified kraft pulps and their impact on lignin determinations was investigated. The lignin analyses investigated were kappa number and Klason lignin in conjunction with acid-soluble lignin. The species investigated were loblolly pine, and aspen. The non-lignin components that impacted on lignin determination were residual extractives and hexenuronic acid in unbleached and oxygen-delignified kraft pulps. In the hardwoods, significant amounts of extractives remained after kraft pulping and oxygen delignification. These residual extractives in the hardwood pulps had an impact on the lignin determination, more so on the acid lignin method than kappa number. Hexenuronic acid only impacts on kappa number determination both softwood and hardwood pulps, not on acid lignin. Hexeneuronic acid contributed as lignin content more in aspen than pine pulps, and more in oxygen-delignified than unbleached kraft pulps. Impact of hexenuronic acid on should be corrected both softwood and hardwood pulps for accurate kappa number.

It is generally known that paper industry is the second largest industry in the use of process water, and also have the highest environmental impact load in the contaminant sources. Paper is produced from the mixtures composed of 1% fibrous raw materials and 99% water. The optimum use of process water effects on the quality properties of paper and the environmental impact load of waste water treatment. In this research, the kinds of fibrous raw material & additives used in the paperboard production line were investigated, and the quantification of environmental loads and the environmental effects of process water on COD potential were evaluated. The NBDCODs were also analyzed from process water by the method of waste water treatment in paper mill and applied for the optimum use of recycling water, and zero effluent process. In the fibrous raw materials, KOCC caused the highest COD potentials, and sack paper & UKP was comparatively low. The NBDCOD of KOCC largely reduced after biological treatment because of easily biodegradable properties, but AOCC contained non-biodegradable materials. In chemical additives, COD was high in turns of rosin>starch>deaeration agent>dye, NBDCOD greatly reduced in starch and deaeration agent. In the case of 2 kinds of paperboard product, the COD potentials was mainly high in starch, AOCC and KOCC.

In this study, three kinds of linepipe steels were processed by changing the amount of Mo and Nb to investigate the effects on microstructures, tensile and Charpy impact properties. All the specimens consisted of acicular ferrite, granular bainite and secondary phases such as martensite and austenite constituents (MA). The increase in Mo raised the volume fractions of the granular bainite and MA, and raised the number of fine precipitates, which increased the yield and tensile strengths and decreased the upper self energy and energy transition temperatures. In the steel having less Mo and more Nb, the volume fractions of the granular bainite and MA decreased, and a finer microstructure was observed. This microstructure suppressed the formation of separation during Charpy impact testing and led to a higher upper shelf energy and lower energy transition temperature, while the yield and tensile strengths were lower than those of the steels with more Mo and less Nb.

With the advent of the WTO system in 1995, non-tariff barriers including technical barriers to trade(TBT) has become one of the important issues in world trade order. The purpose of this study is to analyse an impact of the calibration and measurement capabilities(CMC), the degree of equivalence of national measurement standards which is maintained by NMIs to provide governments with a technical foundation for wider agreements related to international trade. The results of the analysis using the gravity model with the proxy of the CMC shows that the CMC has a positive impact on Korean trade. Particularly, it was estimated that the CMC registered by high-income economies has more impact on Korean trade than those by low income economies. This implies that the countries highly dependent upon foreign trade like Korea need to have much more interest in the investment into measurement standards and science which is generally considered to be a public goods.

The paper proposes an analytical framework for the impact of technical change on business model innovation. Based upon the examination of the relationship between the mission of business and technology, it introduces classification of technology-based business models such as problem-solving model, production model and network model, respectively employing intensive technology, interlinked technology and mediating technology as a key technology. The discussion of various cases of business model innovation shows that the impact of digital technology is first translated into the value generation in terms of efficiency or effectiveness. These new values then enable a new business model which is based on a different key technology through business model shift, expansion, unbundling, or platform. Quite often those business model changes involves system-wide innovation. The framework for the analysis of the impact of technical change on business model innovation is presented with directions for future research.

The Environmental Impact Assessment(EIA) System has grown up as an adult today in Korea(ROK). It seems that we have only focused on the specific and technical aspects of the assessment without looking at the whole concept during the past 20 years. Thus we have accomplished quantitative growth but not qualitative development at all. This is the right time we should reconstruct the concept and move into the step for qualitative development. It is expected that the corpulence of the EIA system would be enlarged due to the introduction of integrated impact assessment system. It is necessary to introduce a newly designed method into the EIA methodology and improve the Environmental Impact Assessment based on in order to accomplish and manage more effective EIA system. To the conclusion, it is highly necessary to formulate a wholly new system which can be useful to improve the existing various systems and to follow the fundamental concept of EIA.
