  • Gravel Compaction Pile (GCP) method is currently being designed and constructed by empirical method because quantitative design method has not been developed, leading to various types of and frequent destruction such as expansion failure and shear failure and difficulties in establishing clear cause and developing measure to prevent destruction. In addition, despite the difference with domestic construction equipment and material characteristics, the methods applied to the overseas ground is applied to the domestic as it is, leading to remarkable difference between applied values and measured values in variables such as bearing capacity and the settlement amount. The purpose of this study was, therefore, to propose a reasonable and safe design method of GCP method by analyzing the settlement and stress behavior characteristics according to ground strength change under GCP method applied to domestic clay ground. For the purpose, settlement amount of composite ground, stress concentration ratio, and maximum horizontal displacement and expected location of GCP were analyzed using ABAQUS. The results of analysis showed that the settlement and Settlement reduction rate of composite ground decreased by more than 60% under replacement ratio of 30% or more, that the maximum horizontal displacement of GCP occurred at the depth 2.6 times pile diameter, and that the difference in horizontal displacement is slight under replacement ratio of 30%.

  • As political circumstances in oversea countries and Korea varies, the risk of vulnerability from unexpected extreme loading conditions, such as explosions or extreme impacts, also increased. In addition, construction companies in Korea recently have taken chances of overseas expansion to countries where their domestic situations are not in rest. Therefore, the resistance of construction materials for blast or impact loading become taking more consideration from engineering field. This study is a part of the research to develop a high performance fiber reinforced cementitious composite materials with high volume steel fibers and primary purpose of this study is to find an optimum mix proportions of in-fill slurry. In order to accomplish the tasks this study performed experimental investigations on the slurry for consistency, compressive strength, flowability, J-penetration, bleeding and rheology properties as well as mechanical properties, compressive and flexural strength, with respect to different mix proportions.

  • The Assembly plenary session on December 3, 2017 passed a Product Liability Amendment bill that introduced clauses concerning consumer burden of proof and punitive damage reimbursement. More specifically, these newly approved provisions will reduce the burden of proof placed on consumers and levy triple punitive damage on suppliers. Significant increases in the number of product-liability lawsuit and the number of related insurance contracts are expected. Since military aircraft are designed for operational purpose(seeking greater combat effectiveness over greater safety) and used in high-risk environment, it is practically impossible to obtain an affordable product-liability insurance, Without having any backup plan, military aircraft manufacturers directly face all sort of liability risks under Product Liability Act, Warrant Liability Act and Non-Performance of Contract Act. The U.S. experienced similar problems when they first implemented their product-liability law in 1970s. There had been a big dispute among legal practitioner, insurance professionals and scholars concerning military aircraft manufacturer's liability. In order to settle the issue, the U.S. Supreme Court has established a new precedent of Government Contractor Defense(GCD). The U.S. government also included an indemnity clause for military aircraft manufacturers in their FMS Contract with the Korean government. Likewise, Korean military aircraft manufacturers should 1) clearly understand their current position that they cannot afford expensive product-liability insurance and the cost is not accounted in the military procurement calculation, 2) estimate potential liability risks with the ongoing overseas export expansion in mind, 3) set up appropriate risk management measures through regulatory reform and policy development.

  • The purpose of this study is to explore the necessity of technology commercialization aiding service from government-supported R&D institutions and find key success factors for market performance improvement of business ventures and SMEs. For this aim, we researched relevant theories and KICET(Korea Institute of Ceramic Engineering and Technology)'s "Ceramic Hidden Champion Supporting Project. As government-supported R&D institutions, KICET is not only providing its original main service which is technology advising and development, but also providing a full range of technology commercialization aiding service for business ventures including diagnosis, strategy planning, capital procurement, overseas marketing activity. Qualitative analysis based on relevant theories and meta-analysis framework suggest that such expansion of services is desirable for government-supported R&D institutions to increase market performance of business ventures and SMEs. To lead this business to success, we should develop effective management system and incentive system for external supporting companies and client companies. Also, coordination between team member's activities and budget procurement issue should be solved for further performance creation.

  • These days, ISIS terrorists have been expanding not only to european countries, but also to asian countries so South Korea is no longer safe from terrorists' attacks. Especially, 'soft target terrorism' makes many people maximizing fear of terrorism because it is caused by small groups - those who are armed with small arms and light weapons - and they are able to carry out hit and run attacks on civilian targets. It poses even more dangerous to kill massively. That is why November 2015 Paris attacks and January 2016 Jakarta attacks killed and injured many people because of 'soft target terrorism.' Therefore, the South Korea has also recognized the seriousness of terrorism by ISIS. The study has shown the precautionary measures about 'soft target terrorism' and how to defend against 'soft target terrorism' by looking through overseas examples. It is for the possibilities of 'soft terrorism' in South Korea because of the expansion of ISIS. As a result, 'soft target terrorism', caused by ISIS, could happen in South Korea. The counterplan is as in the following. First of all, 'soft target terrorism', which is collaborated with ISIS and domestic terrorists, could be caused by negative awareness of foreign residents and xenophobia so the public should change stereotypes about the foreign residents and there should be legislation about racial discrimination enacted by parliament and the government must practice the law. Second, the Korean anti-terrorism laws should be modified to minimize violations of human rights, related to the Korean citizens' personal information, and to stop the concentration of power into the hands of one law enforcement. Third, the government has to develop and to initiate the refuge&evacuation simulation, which prepares for 'soft target terrorism' and minimizes the damages if terrorists attack hot spots like central commercial areas or event halls.

  • The BIM design is expected to expand to the domestic and overseas construction industries, depending on the effect of construction productivity and quality improvement. However, with the obligation of Public Procurement Service to design the BIM design, it includes a design error and the problem of utilization of 3D design by choosing a simple 2D to 3D remodelling method that can not be modelled in 3D modeling or use of the construction and maintenance phases. The results reviewed by BIM design results were largely underutilized and were not even performed with the verification of the error. In order to resolve this, one must develop the check system that secures the quality of BIM design and ensure that the reliability of BIM results are available. In this study, it is designed to develop a program that can automatically verify the design of the BIM design results such as violation of the rules of the BIM design, design flaws, and improve the usability of the BIM design. In particular, this programs were developed not only to identify programmes that were not commercially available, but also to validate drawings in low-light computer environments. The developed program(LH-BIM) store the information of attribute extracted from the Revit file(ArchiCAD, IFC file included) in the integrated DB. This provides the ability to freely lookup the features and properties of drawings delivered exclusively by the LH-BIM Program without using the Revit tools. By doing so, it was possible to resolve the difficulties of using traditional commercial programs and to ensure that they operate only with traditional PC performance. Further, the results of the various BIM software can be readily validated, which can be solved the conversion process error of IFC in the case of SMC. Additionally, the developed program has the ability to automatically check the error and design criteria of the drawings, as well as the ability to calculate the area estimation. These functions allow businesses to apply simple and easy tasks to operate tasks of BIM modelling. The developed system(LH-BIM) carried out a verification test by reviewing the review of the BIM Design model of the Korea Land & Housing Corporation. It is hoped that the verification system will not only be able to achieve the Quality of BIM design, but also contribute to the expansion of BIM and future construction BIM.

  • The sustainable operation and development of ports is a key industry for Korea's national economy. It is increasingly more important to resolve conflicts with local communities due to port environmental problems such as air pollution, water pollution, noise and ecosystem destruction while securing port competitiveness through infrastructure expansion. In case of the Busan New Port development project in Korea, construction has been temporally suspended due to conflict with local fishermen over marine sand mining for construction. A primary reason for this is the absence and limitation of qualitative port environmental impact assessment methodologies in Korea. This includes the current investigation of fisheries damaged by ports. Therefore, the main purpose of this study is to propose economic valuation methods for assessing environmental impacts that are essential for efficient port environmental management and for sustainable port operation and development in Korea. To do this, this study examines the overall port environmental problems and their effects (damages) through the analysis of environmental policies and case studies of domestic and overseas ports. Then economic valuation methods are suggested for total economic values (TEV) of damaged environmental goods and services. Among the proposed methods, Habitat Equivalency Analysis (HEA), as a more scientific data based method, was applied to estimate marine ecosystem service damages from the designation of Busan New Port Anchorages. Finally, based on the study results, more efficient port environmental management will be achieved through the institutional adoption of the proposed economic impact assessment methods for port environmental damages.

  • Objectives The purpose of this study is to help improve the management of traditional Korean medical(TKM) clinics and the policies for supporting them, by conducting a survey of the practitioners of TKM. Methods Stratified sampling was conducted based on regional location, and 700 samples were selected in a random manner from the membership list. The questionnaire was delivered and returned by mail. The survey was conducted between 20 July and 31 August 2010. A total of 177 questionnaires (recovery rate: 25.28%) were recovered and analyzed for the study. Results 1. The the survey indicate that the overall size of TKM clinics has fallen compared with previous survey, while the average number of beds per clinic has remained unchanged at 7.9. The sale of medicine as a proportion of total monthly sales has increased. 2. There has been no change in the composition of clinical staff as there are three nursing assistants. Although the average daily number of patients to clinics has remained at around 33.90 compared with ten years ago, the number of patients requiring seeking acupuncture treatment has increased while the number of those treated with medication has decreased. 3. Clinicians in TKM have indicated their preference for a binary system that separates TKM from western medicine (57.4%). The respondents do not favor the separation of dispensary from medical practice (81.5%), marks of origin for medicinal herbs (68.9%), disclosure of the prescriptions (67.2%), and the overseas expansion of Korean medical services (70.4%). However, they indicated that they are very much in favor of being granted the authority to employ and give orders to medical technicians (96.0%). 4. The respondents selected Korea as the country that maintains a proper academic system for traditional medicine (45.5%), and are not in favor of opening Korea's traditional medicine market under an Free Trade Agreement(FTA) with China (72.7%). Conclusion The overall status of the management of TKM clinics has declined compared with the preceding decade. There has been only a slight change in clinicians' opinion of the related policies and regulatory issues.

  • This study researches on global technology trend in each of composing technology, such as grouting material, grouting equipment, and construction management technology, which grouting technology has been founded upon to improve relatively inadequate domestic grouting technology and to establish the global standard for overseas expansion in the future. As far as grouting material is concerned, while High-Penetration and High-Strength micro cement ($1.5{\mu}m$) has been developed in 2000's in Japan, JinChun Kim et al. (2014) has been developing hybrid type micro cement grouting material and examining specifications of different kinds of projects and countries to analyze the trend of grouting equipment development. The specification contains detailed requisite specification for materials, mixers, pumps, agitators, and packers and it has to satisfy the standard of different countries to win global contracts. Grouting management technology can be divided into four different generations and Scandinavian countries, such as Sweden, Norway, and Finland, Japan, and South Korea are recently doing vigorous researches on the Fourth generation which merges grouting technology with ICT.

  • Ramyeon is a wheat-food that has been mixed a dietary culture of China, Japan, American and Korea. Simultaneously it was the first convenience food that made of flour in Korea, which had been relatively few recipes until the early 1960's. To examine the changes of Ramyeon which has been consumed in large quantities since the late 1960s, this paper classified 1963~2012 into 6 periods. From political, economic, social, cultural and international perspectives we considered the changes of Ramyeon through the articles analysis of mass media(DongaIlbo, The KyunghyangShinmun, MBC news). The total number of articles was 3,823 with an average of 76.46/y. Each field was summarized as following sub-topics; In political(Election, North Korea), in economic(Price, Economy), in social(Promotion campaign for eating of flour, Incidents, Donation), in cultural(Consumption, Extreme situations, Nutrition) and in international field(Exporting). Each period was named according to the feature; Early stage, Expansion stage, Domestic growth stage, Overseas stage, Advanced stage, Transition stage. Ramyeon has changed in a closely relation with society for past 50 years.
