The crisis of science-engineering field is a significant problem which hinders the improvement of national competitiveness. In this study, we use a structural equation model to propose two kinds of satisfaction indices of engineering education: m index for major and p index for personality. They are used to improve the current situation of engineering education in Korea. Based on the resulting feedback information, we suggest several strategic plans for science-engineering field.

The purpose of the establishment of corporation's Business Continuity Plan(BCP) is to maintain corporations' own business and establish the response plan in order to resume operation in a short time period when crisis situations occur due to natural disaster and human error. This study has presented all types of procedures and criteria which are needed to establish the airport crisis response system in order to maintain the business continuity by utilizing BCP technique. Basically the risk response procedures must be established in the process of (1) preparation stage, (2) plan development stage, (3) documentation stage, (4) test & maintenance stage. The guideline has been suggested that each stage must be carried out in the sequence of Policy & Planning Responsibility, Business Impact Analysis, Recovery Strategy & Plans, Emergency Plan & SOP, Training Awareness and Maintenance & Review

This study examines a cointegrated vector autoregressive (VAR) model where parameters are subject to switch across the regimes in the term structure of interest rates. To employ the regime switching framework, the Markov-switching vector error correction model (MS-VECM) is allowed to the regime shifts in the vector of intercept terms, the variance-covariance terms, the error correction terms, and the autoregressive coefficient parts. The corresponding approaches are illustrated using the term structure of interest rates in the US Treasury bonds over the period of 1958 to 2009. Throughout the modeling procedure, we find that the MS-VECM can form a statistically adequate representation of the term structure of interest rate in the US Treasury bonds. Moreover, the regime switching effects are analyzed in connection with the historical government monetary policy and with the recent global financial crisis. Finally, the results from the comparisons both in information criteria and in forecasting exercises with and without the regime switching lead us to conclude that the models in the presence of regime dependence are superior to the linear VECM model.

The importance of managing blind spots in the welfare crisis is increasing. Accordingly, in order to manage the blind spot of the welfare crisis, it is necessary to manage the social safety net with the contents of supporting income and self-reliance of low-income families, and actively discovering and supporting poor and crisis households. In this paper, we reviewed various problems related to blind spots for the management of welfare blind spots, and proposed the applicability of blockchain-based distributed ID and the possibility of distributed ID technology in stages by considering the range of blind spots.

As clean water continues to be a demand in this global water crisis, development of separation membrane technology for water purification becomes a necessity. The effectiveness of separation membranes is hindered in the water crisis due to fouling of membranes. To address this problem, the application of patterns on flat membranes via various methods have been recently studied and experimented. Patterned membranes have shown to not only reduce the fouling effects of membranes, but also increase the fluxes depending on the method and materials used. Each application has shown benefits that include, but not limited to, enhanced surface area, higher pure-water permeability, and increased number of filtration cycles. In this review, the effects of patterned membranes against antifouling is summarized and discussed.

As disaster potential power of modern society grows larger, to improve and reinforce efficiently a national system which prepares and responds disasters, analyzed the survey for government officials of the department disaster management. Following is the contents of this research. First, cooperative relationship to disaster management organizations. Second, necessity of law establishment related crisis and disaster department. Third, by recognition regarding disaster management situational variable, overall recognition regarding disaster management situation, overall recognition regarding crisis type, recognition regarding occurrence possibility along disaster scale. Fourth, by recognition regarding structural variable of disaster management, the National Emergency Management Agency regarding disaster management, related organization, recognition difference of local government. It is a research about confusion regarding step of prevention - preparation - correspondence - restoration.

Simulators were introduced in education as a tool to make advanced training standardized, less expensive, and without danger to those involved. In 1922 in the Unites States, Edward Link presented his homemade flight simulator, which became common place in both military and civilian aviation, known as the "Link Trainer". The development of mannequin simulators used for medical simulation education, training, and research is reviewed, tracing the motivations, evolution to commercial availability, and efforts toward assessment of efficacy of those for teaching cardiopulmonary resuscitation(CPR) for medical personnel and emergency medical technicians(EMT), cardiology skills, anaesthesia clinical skills, and crisis management. This study will provide a brief overview of simulators and trainers in several domains.

안보, 재난, 국가핵심기반 분야에 위기발생시 즉각적인 조치를 위한 '위기대응 실무매뉴얼'이 정부기관별로 작성되어 있지만 조치사항에 대한 정량적 검증이 부족하다. 오류가 내포된 조치절차는 피해를 확대 시킬 수 있으므로 위기대응절차에 대한 검증이 요구되며 이를 위해 본 논문에서는 Statemate의 구조적, 기능적, 행위적 관점의 언어를 활용해서 정형기법(formal methods)을 수행함으로써 위기 대응 실무매뉴얼의 모델링 방법을 제안하고 매뉴얼에 기술되어 있는 조치절차의 검증결과를 제시하였다.

The history of polyurethane is relatively shorter compared to that of the other polymers, though its importance has grown rapidly. Due to its unique properties, polyurethanes are widely applied in various fields. In particular, the automotive industry is one of the important application fields. To date, polyols and isocyanates used in the polyurethane industry are generally of petrochemical origin. Recently, owing to the oil crisis, legislation, and growing awareness towards environmental preservation, the demand for more sustainable and eco-friendly raw materials has increased. In this paper, the latest research and development trends in polyurethane applications were reviewed, with a focus on the automobile industry in areas such as seat comfort, noise reduction, light weight, biomass-based polyurethane, and recycling.
