  • Technology-intensive industries can be used as a major growth engine for resource poor country in the territories. For example, in the case of Korea, nuclear power and radiation technology industry was highly developed, and it was possible to obtain national interests such as solving energy problems within the country and exporting nuclear power plants. On the other hand, there are cases where national damage is caused by erroneous governmental policy-making on technology-intensive sectors. In this study, we analyzed cases of misguided governmental policy-making for technology-intensive industry and three factors were identified. And we tried to develop a rational policy-making model using three types of allison's model in combination. The results of this study are expected to be useful for rational governmental policy-making processes for technology-intensive industries.

  • As the number of cyberattacks against the National Critical Information Infrastructure (NCII) is steadily increasing, many countries are strengthening the protection of National Critical Information Infrastructure (NCII) through the enactment and revision of related policies and legal systems. Therefore, this paper selects countries such as the United States, the United Kingdom, Japan, Germany, and Australia, which have established National Critical Information Infrastructure (NCII) protection systems, and compares and analyzes the promotion system of each country's National Critical Information Infrastructure (NCII) protection policy. This paper compares the National Critical Information Infrastructure (NCII) protection system of each country with the cybersecurity system and analyzes the promotion structure. Based on the policy model theory, which is a modification of Allison's theory and Nakamura & Smallwood's theory, this paper analyzes the model of each country's promotion system from the perspective of policy-making and policy-execution. The United States, Japan, Germany, and Australia's policy-promotion model is a system-strengthening model in which both policy-making and policy-execution are organized around the protection of the National Critical Information Infrastructure (NCII), while the United Kingdom and South Korea's policy-promotion model is an execution-oriented model that focuses more on policy-execution.

  • A total life model was developed to assess the service life of aging aircraft. The primary focus of this paper is the development of crack growth life projection using the response surface method. Crack growth life projection is a necessary component of the total life model. The study showed that the number of load cycles N needed for a crack to propagate to a specified size can be linearly related to the geometric parameter, material, and stress level of the component considered when all the variables are transformed to logarithmic values. By the Central Limit theorem, the ln N was approximated by Gaussian distribution. This Gaussian model compared well with the histograms of the number of load cycles generated from simulated crack growth curves. The outcome of this study will aid engineers in designing their crack growth experiments to develop the stochastic crack growth models for service life assessments.

  • 본 연구는 대표적인 지식기반산업인 생명의료산업클러스터인 첨단의료복합단지 조성정책의 형성과정을 분석하고자 한다. 첨단의료복합단지는 미래첨단산업육성정책, 국가산업진흥정책 그리고 지역균형발전정책이 첨예하게 대립했던 첨단의료산업 발전정책과 그 산물로서 2005년부터 시작한 첨단의료복합단지의 건립과정에 대한 경과를 분석하여 그 과정, 절차 그리고 결과를 분석해 보고자 한다. 첨단의료복합단지를 둘러싼 정책형성과정에 대한 분석은 단지 하나의 이벤트나 사건으로 머물지 않고 우리나라의 미래첨단산업정책, 국가신성장동력육성정책, 및 지역균형발전정책 등과 밀접히 관련되어 있다는 데 그 의의를 두고자 한다. 분석결과 첨단 의료산업분야의 정책형성 과정은 여러 정책행위자들이 간여하였다. 특히 해당 정책형성과정은 경제발전과정에서 보여준 한국 산업정책 고유특성이 반영된 합리적 행위자로서의 정부역할이 강하게 나타났다. 아울러 분석결과 다양한 정책행위자의 역동적인 역할이 정책형성의 여러 지점에 반영되었다는 점을 조명하였다.

  • The purpose of this study is to classify the lifelong learning policy implementation process of lifelong learning in Korea according to the policy making decision models and to suggest developmental tasks. Korea's lifelong learning policy came to a full-fledged start with the enactment of the Lifelong Education Act in 2000. The Lifelong Education Act proposed the establishment of an open educational system as a strategy to realize the lifelong learning society. According to the Lifelong Education Act, the Korean government has developed several lifelong education policies such as providing learning opportunity for the underprivileged, facilitating lifelong learning city project, building lifelong learning culture, recognizing of experiential learning result, funding lifelong learning hub university, launching lifelong learning supporting administrative etc. The Korean lifelong system is characterized as Allison's (1971) governmental/bureaucratic, Ziegler and Johnson's (1972) legislative, Griffin's(1987) social control and Green's (2000) state-led models which make policy through the coordination between the government and the parliament and control bureaucratic power and educational qualifications. Lifelong learning policies should be managed in terms of supply and demand at the learning market. In addition, the state has to strengthen lifelong learning through supporting NGOs' activities and adult learners' tuition fee for the disadvantaged group of people.

  • BACKGROUND: Cardiac allograft vasculopathy (CAV) is a complication beyond the first-year post-heart transplantation (HTx). We aimed to test the utility of cardiac magnetic resonance (CMR) to detect functional/structural changes in HTx recipients with CAV. METHODS: Seventy-seven prospectively recruited HTx recipients beyond the first-year post-HTx and 18 healthy controls underwent CMR, including cine imaging of ventricular function and T1- and T2-mapping to assess myocardial tissue changes. Data analysis included quantification of global cardiac function and regional T2, T1 and extracellular volume based on the 16-segment model. International Society for Heart and Lung Transplantation criteria was used to adjudicate CAV grade (0-3) based on coronary angiography. RESULTS: The majority of HTx recipients (73%) presented with CAV (1: n = 42, 2/3: n = 14, 0: n = 21). Global and segmental T2 (49.5 ± 3.4 ms vs 50.6 ± 3.4 ms, p < 0.001;16/16 segments) were significantly elevated in CAV-0 compared to controls. When comparing CAV-2/3 to CAV-1, global and segmental T2 were significantly increased (53.6 ± 3.2 ms vs. 50.6 ± 2.9 ms, p < 0.001; 16/16 segments) and left ventricular ejection fraction was significantly decreased (54 ± 9% vs. 59 ± 9%, p < 0.05). No global, structural, or functional differences were seen between CAV-0 and CAV-1. CONCLUSIONS: Transplanted hearts display functional and structural alteration compared to native hearts, even in those without evidence of macrovasculopathy (CAV-0). In addition, CMR tissue parameters were sensitive to changes in CAV-1 vs. 2/3 (mild vs. moderate/severe). Further studies are warranted to evaluate the diagnostic value of CMR for the detection and classification of CAV.
