Kookmin University is the first national private university located in Seongbuk-gu, Seoul, South Korea after the liberation of the Republic of Korea from Japan. Kookmin University was established in 1946. After South Korea was liberated from Japan, Gu kim, Soang Jo and Ikhee Shin who are the members of the cabinet in a provisional government had agreed to cultivate a great leader among the Republic of Korea in perspective, which soon became the banner of the Kookmin University. Ikhee Shin who is one of the key figures of establishment for the Kookmin University was inaugurated as the first president of the University. Kookmin University is owned by the SsangYong Group, which bought the university in 1959.Kookmin University has an academic family of 22,000 students, about 800 faculty members and 350 administrative staff. Since its establishment in 1946, approximately 60,000 students have graduated.Kookmin University includes the College of Humanities, the College of Engineering and 12 other colleges. The university includes a Graduate school which consists of three Professional Graduate Schools and ten Special Graduate Schools. Kookmin teaches in the fields of Design, Architecture, Automotive Engineering, Techno-Design, Social Science and other academic disciplines.The College of Design held the first rank in three fields and the second rank in two fields among a total of five fields as a result of a nationwide assessment in 2007 in South Korea. The college has been ranked among the top three departments in Korea with Seoul National University and Hongik University.Kookmin University's Graduate School of Techno Design, which was established with the view of nurturing "design human capability of world level", has been selected for the BK 21 project. The Techno Design School's interdisciplinary connection and expertise in educational-industrial cooperation is expected to create synergy with the "UIT design".In the Joongangilbo University Ranking 2011, the School of Economics achieved third in Korea.

In this manuscript, a fast imaging of thin, curve-like electromagnetic inclusions completely hidden in the homogeneous domain with smooth boundaries is considered. By creating an electromagnetic inclusion of a small diameter and applying the asymptotic expansion formula in the existence of such an inclusion, the topological derivative is successfully derived. Based on this derivative, a one-step iteration imaging algorithm is designed by solving an adjoint problem. Various numerical experiments of single and multiple inclusions demonstrate the viability and limitation of the designed algorithm. © 2011 Elsevier Inc. Source

As DDoS attackers pursue monetary profit, critical Internet sites (CISs) become a good target. These attacks will be more difficult to defend because the botnet size continuously increases, and the attackers spare no pains in preparing the attacks. Under this new paradigm, current anti-DDoS systems may be fooled; we need a new survival strategy. We propose a novel DDoS mitigation scheme for CISs. We observe that CISs can continue their main businesses if most important clients can access the services. This motivates us to build a whitelist, called a VIP list in this article, and the source addresses in the list are given higher priority when the CIS is under attack. The VIP list is built from the previous login logs of authentication processes at the application layer. The experimental results show that the proposed scheme effectively mitigates DDoS attacks. © 2006 IEEE. Source

Recently, much progress has been made toward the fabrication of non-volatile memory devices based on metallic nanoparticles. Among the many kinds of nanoparticles, gold nanoparticles are some of the most widely used materials for charge trapping elements in non-volatile memory devices because they are chemically stable, easily synthesized, and have a high work function. Various synthesis methods have been applied to fabricate gold nanoparticle-based nonvolatile memory devices and recent progress indicates that gold is a very promising material for non-volatile memory applications. In this article, the recent advances in fabrication and characterization of gold nanoparticle-based nonvolatile memory devices, with an emphasis on flash memory-type memory devices, are reviewed. Detailed device fabrication, characterization, and future directions are reported based on the recent research activities and literature. Source

Objectives: We test (McIntyre and Kacerosky's [2011]: Am J Hum Biol 23:305-312) prediction that the relationship between age at menarche and height switches from negative to positive, in a unidirectional and smooth manner, as the society industrializes. According to this prediction, a mid-level industrial country should exhibit a weak relationship between the two variables. Methods: The 8,013 observations are extracted from the Indonesian Family Life Survey, a nationally representative survey. Indonesia is an intermediate case that exists between the small-scale agrarian societies and industrialized societies examined by McIntyre and Kacerosky. While age at menarche is a recalled and self-reported variable, height is a measured one. The relationship is informally provided in a figure and formally estimated using ordinary least squares (OLS). Results: The informal finding clearly shows no relationship between age at menarche and height. The OLS results also agree that the relationship is very weak. Specifically, despite the large sample size, the relationship is not statistically significant in a linear manner, regardless of whether the outlier group (age at menarche 10) is included or excluded. Various robustness checks are performed to confirm this finding. Conclusions: Our results lend support to McIntyre and Kacerosky's explanation as to why the relationship between age at menarche and height switches from negative to positive as the society industrializes. Furthermore, our results imply that the model (the Day and Rowe model) and theory (life history theory) on which this explanation is based are plausible. Am. J. Hum.

Obesity is pandemic, but no consensus has yet emerged regarding appropriate tools for measuring it. Medical research based on populations in the developed world has largely dismissed body mass index (BMI) because it is a weak predictor of some health outcomes. In contrast, social science research still relies on it for its simplicity and ready availability in surveys. This paper uses consistent definitions and measures to select sufficiently good predictors of health and economic outcomes from among the anthropometrics that are considered alternatives to BMI. The results from the Indonesian Family Life Survey indicate that BMI and waist circumference are better predictors than waist-to-height ratio and waist-to-hip ratio. This paper argues that given its advantages, BMI is an adequate measure of obesity for Indonesia and possibly for the developing world. Further, if BMI is to be replaced, waist circumference is preferable to other anthropometrics. Copyright © 2014 Cambridge University Press. Source
