As the number of clinical trials conducted in Korea increases, the need of the Electronic Data Capture (EDC) system for effective clinical data management is also increased. Recently, the Korea Food and Drug Association published 'Guideline for the Electronic Clinical Trial Data Management and Processing' and it would be the foundation for establishing regulation of electronic clinical data management. In this research, we conducted the survey regarding adoption rate of EDC system in clinical trials in hospitals, Contract Research Organizations (CRO), and pharmaceutical companies. And the perceived importance and the ease of application for the Guideline were investigated. The adoption rates of EDC system was 77.6% but it mostly applied to less than five trials. Also EDC system was mostly used in phase I and phase II trials and the utilization rate of CRO was the highest. The perceived importance for the Guideline was high among all three organizations but, in case of the perceived ease of its application, CRO was the highest. Also, the perceived importance of the clinical data standard was high and the standard for data collection was mostly required. However, the comprehension for the global standard of the electronic data was relatively low, so that education is required. This result would be the foundation to increase the electronic clinical trials and develop proper regulation and principles for clinical data standards in Korea.

Recently, it is certain that the increase of heating and cooling energy consumption by radical change in climate condition has caused serious problems related to environmental and energy concerns associated with increase of fossil fuel usage and carbon dioxide production as well as global warming. So, various actions to reduce greenhouse gas exhaustion and energy consumption have been prepared by world developed countries. Our government has also been trying to seek energy control methods for houses and buildings by proclaiming political polices on low-carbon green growth and construction and performance standards for environment-friendly housing. The energy consumption by buildings approximately reaches 25% of total korea energy consumption, and the increasing rate of energy consumption by buildings is stiffer than the rate by the other industries. The greatest part in the buildings of the energy consumption is building facade. While lots of research projects for reducing energy consumption of the facade have been conducted, but a few research projects on concrete comprising more than 70% of outsider of buildings has been tried. This research presents here a study to improve the insulation property of structural concrete formed by micro form admixture (MFA) with experimentally reviewing the physical, mechanical and thermal characteristics of the concrete. As the results of this experiment, in the case of concrete mixed with MFA, slump loss has been improved. As the mixing ratio of MFA increases, the compressive strength is decreased and thermal conductivity is increased. Also it was found that water-cement ratio increases, the compressive strength is decreased and thermal conductivity is increased. but, there was not big influence by the change of fine aggregate ratio.

The ISO issued the first standard for environmental management standard(EMS) in 1993. This standard provide for elements of an effective environmental management system and can also help companies ingrain effective environmental management practice into their overall business operations. ISO 14001 is predicted to become the leading voluntary environmental management system standard. Companies selling products and services internationally and domestically will also be affected by publication of this standard. Especially, this new environmental management standards are fast becoming a condition for doing global business because it can be acted with trade barriers. Actually, an automobile companies of America including Ford and GM require their subcontracting companies to gain the recognition of ISO 14001. The purpose of this paper is to investigate the ISO 14000 and its application of Korean firms focusing on environmental management system(EMS). This paper proceeds to present the effective alternatives through analysing the existing Korean firms which has established EMS. Korean firms should adopt EMS not for the enhancement of corporate image but for the purpose of strategic competitive advantage.

The Korean economy has sustained high growth rate for almost three decades, that have been associated with the rapid expansion of manufacturing industries. In the beginning stage of development, the high growth of the Korean economy has been based on improvements in productivity obtained by the economies of scale. In that period, the improvements in productivity could be secured by the economies of scale in the export-oriented industries which are the labor- and material-intensive industries. In the latter half of the 1980s, the Korean economy went through rapid transition. Now Korea is at another juncture in its development process, where economic restructuring is critical to sustain high growth. However, economic restructuring in the 1990s call for much more concerted effort than before, since changes in internal and external conditions have profoundly altered the environment for economic development. If Korea is to sustain high growth in the 1990s, it has to promote balanced economic and social development in coordination with the smooth facilitation of industrial restructuring. There are no inherent conflicts among the issues involved, so they can be resolved by restructuring the economy to facilitate, in a global context, the development of knowledge- and technology-intensive activities and to ensure that the benefts of growth are reflected of qualitative improvements in national living standards. In this paper, we examined a scenario of structural changes using a mid- and long-term multisector model, in order to understand the conditions needed for realizing the growth potential. This examination explains the important features of the development course and policy directions that will help sustain high growth in the 1990s.

This article deals with the nature of ISDS along with the admissibility thereof, for the settlement of investment disputes between states and nationals of other states. ICSID as an organization of World Bank Group, has been established in 1966 and as of May in 2011, 157 nations ratified its convention. As for the Republic of Korea(ROK) it has been involved in the problematic situation with regard to ISDS of the KORUS FTA in negotiation with the United States. The ruling Grand National Party is pushing the FTA for ratification including ISDS. However, the opposition party, the Unified Democratic Party rejected the ISDS with a view to a toxin infringing on its judiciary sovereignty. The ROK has invested in the US 3.5 times more than the US did in Korea up to now. As a result, it seems that the ROK is more concerned about ISDS than the US is, considering that exhausting local remedy through the US local courts, applying even a municipal ordinance in their decisions which will be unsatisfactory toward the ROK side. The ROK is now struggling with the ISDS as a political issue between the ruling party and the opposition party mostly based on sovereignty with a reference on AUSFTA which excluded the ISDS. Australian model about ISDS has been impacted by the experience from the NAFTA which allowes direct claims against each other(the US against Canada and Canada against the US). It seems not to be much sympathy for developed countries because it has long been held to standards for pressing on developing countries. Australia is also struggling with ISDS from the political point of view likewise the ROK. And the ISDS is destined to the political situations established within the domestic countries among the political parties in relation with the acceptance or rejection of thereof.

Currently, due to global warming, occurrences of extreme climate phenomena such as heat wave, heavy snow, heavy rain, super typhoon are continuously increasing all over the world. Due to these extreme climate phenomena, concrete structures and infrastructures are exposed to serious deterioration and damage. However, researches on construction technologies and standards to confront the climate change generated problems are needed presently. In order to better handle these problems, the validity of the present concrete mixture proportions are evaluated considering wind speed and sunlight exposure time based on climate change record in Seoul, Korea. The specimens cured at various wind speed and sunlight exposure time conditions were tested to obtain their compressive and split tensile strengths at various curing ages. Moreover, performance based evaluation (PBE) method was used to analyze the target strength satisfaction percentage of the concrete cured for the curing conditions. From the probabilistic method of performance evaluation of concrete performance, feasibility and usability of current concrete mix design practice for climate change conditions can be evaluated.

With the increase in occurrence frequency and severity of natural disasters due to climate changes arising from global warming, damage in the landscaping field is rising. This leads to legal disputes, and is increasing social and economic damage, too. Especially even though landscape trees which are highly affected by external environments, suffer lots of damage from natural disasters, there is no specific scope of disaster criteria and thus it brings plenty of problems of damage restoration and compensation. Therefore, this study aims to suggest that gives ways to improve related criteria for damage of landscape trees from natural disasters. For this objective, this study analyzed damage cases of landscape trees and precedents, and compared Korean and Japanese legal systems and criteria regarding natural disasters with each other. The analysis result showed that opinions of experts have a great deal of influence on judgment results, since there is no definite legal basis on damage from natural disasters in the landscaping field. This implies the need for a professional and objective appraisal process. According to the comparative analysis of Korean and Japanese legal systems and criteria regarding natural disasters, Korea lacked in laws and criteria on natural disasters of landscape plants in Korea, whereas there were concrete disaster assessment standards of landscape trees in Japan. For improving natural disaster-related systems and criteria in the landscaping field, therefore, this study presented 'Revision of related laws', 'Revision of appraisal and loss assessment criteria', 'Revision of standard specification of landscaping project', 'Compulsory insuring against disasters', 'Reasonable fulfillment of contract', and 'Compulsory cost estimation for disaster restoration', as improvement plans.

Recently, the need of alternate energy resources is increasing due to the global warming issue. The natural gas buried in the extremely cold regions of Alaska and Siberia is of much interest these days. However, the construction standards are needed to be used in extremely cold regions. Particularly, more research work need to be carried out on the trench stability so that the safety of the workers is ensured and the damage to the construction machinery can also be reduced resulting in smaller construction period. In this study, the process for lowering of the pipelines of 30 and 40 in. diameters in the ground conditions (silt and peat) of Yakutsk, Russia was analyzed. The slopes of the ground surface were considered as $0^{\circ}$, $10^{\circ}$, and $20^{\circ}$ to be excavated in summer and winter. The analysis results show that the weight of pipelayer affects the trench stability. Numerical analysis was performed by considering the types of pipelayers, distance between the trench and pipelayer, and the distance between the pipelayers placed longitudinally along the trench. The results show that as the distance between the pipelayer and the trench decreases, the factor of safety of the slope decreases with an increase in the slope of the ground surface. When the slope of the ground surface was $20^{\circ}$, the breakout surface was anticipated to continue from the pipelayer to the trench boundary. In winter season, stability problem of the trench was not observed when the slope of the ground surface was less than $20^{\circ}$.

Energy supply is increasingly showing up as a major issue for electricity supply, transportation, settlement, and process heat industrial supply including hydrogen production. Nuclear power is part of the solution. For electricity supply, as exemplified in Finland and France, the EPR brings an immediate answer; HTR could bring another solution in some specific cases. For other supply, mostly heat, the HTR brings a solution inaccessible to conventional nuclear power plants for very high or even high temperature. As fossil fuels costs increase and efforts to avoid generation of Greenhouse gases are implemented, a market for nuclear generated process heat will be developed. Following active developments in the 80's, HTR have been put on the back burner up to 5 years ago. Light water reactors are widely dominating the nuclear production field today. However, interest in the HTR technology was renewed in the past few years. Several commercial projects are actively promoted, most of them aiming at electricity production. ANTARES is today AREVA's response to the cogeneration market. It distinguishes itself from other concepts with its indirect cycle design powering a combined cycle power plant. Several reasons support this design choice, one of the most important of which is the design flexibility to adapt readily to combined heat and power applications. From the start, AREVA made the choice of such flexibility with the belief that the HTR market is not so much in competition with LWR in the sole electricity market but in the specific added value market of cogeneration and process heat. In view of the volatility of the costs of fossil fuels, AREVA's choice brings to the large industrial heat applications the fuel cost predictability of nuclear fuel with the efficiency of a high temperature heat source tree of Greenhouse gases emissions. The ANTARES module produces 600 MWth which can be split into the required process heat, the remaining power drives an adapted prorated electric plant. Depending on the process heat temperature and power needs, up to 80% of the nuclear heat is converted into useful power. An important feature of the design is the standardization of the heat source, as independent as possible of the process heat application. This should expedite licensing. The essential conditions for success include: ${\bullet}$ Timely adapted licensing process and regulations, codes and standards for such application and design ${\bullet}$ An industry oriented R&D program to meet the technological challenges making the best use of the international collaboration. Gen IV could be the vector ${\bullet}$ Identification of an end user(or a consortium of) willing to fund a FOAK
