Although a large number of genetic variants have been identified to be associated with common diseases through genome-wide association studies, there still exits limitations in explaining the missing heritability. One approach to solving this missing heritability problem is to investigate gene-gene interactions, rather than a single-locus approach. For gene-gene interaction analysis, the multifactor dimensionality reduction (MDR) method has been widely applied, since the constructive induction algorithm of MDR efficiently reduces high-order dimensions into one dimension by classifying multi-level genotypes into high- and low-risk groups. The MDR method has been extended to various phenotypes and has been improved to provide a significance test for gene-gene interactions. In this paper, we propose a simple method, called accelerated failure time (AFT) UM-MDR, in which the idea of a unified model-based MDR is extended to the survival phenotype by incorporating AFT-MDR into the classification step. The proposed AFT UM-MDR method is compared with AFT-MDR through simulation studies, and a short discussion is given.

This paper presents the development of digital robust fuzzy controller for uncertain nonlinear systems. The proposed approach is based on the intelligent digital redesign(IDR) method with considering the relaxed stability condition of fuzzy control system. The term IDR in the concerned system is to convert an existing analog robust control into an equivalent digital counterpart in the sense of the state-matching. We shows that the IDR problem can be reduced to find the digital fuzzy gains minimizing the norm distance between the closed-loop states of the analog and digital robust control systems. Its constructive conditions are expressed as the linear matrix inequalities(LMIs) and thereby easily tractable by the convex optimization techniques. Based on the nonquadratic Lyapunov function, the robust stabilization conditions are given for the sampled-data fuzzy system, and hence less conservative. A numerical example, chaotic Lorentz system, is demonstrated to visualize the feasibility of the proposed methodology.

교육은 인간 행동의 계획적인 변화이다. 이러한 변화는 인간의 학습 과정을 통해 이루어진다. 학습이 이루어지는 과정과 그 심리적 기제를 설명하는 법칙이나 이론적 체계는 학습이론에 그 바탕을 두고 있다. 학교교육을 지원하는 기본 시설로서의 학교도서관은 교수-학습이론과 어떤 관련이 있고, 어떤 기여를 할 수 있는지, 그 방법은 어떻게 되어야 할 것인지에 대한 객관적 통찰은 학교도서관의 교육적 탐구와 학문적 탐구를 위한 기반이 된다. 본고에서는 학습이론의 큰 흐름인 행동주의 학습이론 인지주의 한습이론, 구성주의 학습이론 등을 중심으로 학교도서관의 교수-학습 이론적 기반을 고찰한다. 이를 바탕으로 학교도서관의 교육적 기초를 도서관기반교육접근법 (LBEA)으로 정립하고 있다.

This paper reviews the relationships between diverse ecological design strategies and competing conceptions of ecological approach in place making. It focuses conceptual trends of what we categorize a building "green" and outlines a social constructive perspective on the development of sustainable architecture. This study classifies seven logics of ecological design-eco-technical, eco-aesthetical, eco-social, eco-medical, eco-renewable, eco-cultural, eco-central - which have their roots in competing philosophies of environmentalism. In my analysis of the logics concerning sustainable architecture, the adapted and incorporated technology from high-tech to low-tech levels is a key issue. These points lead us to propose a way that each logic configures the technological approaches and alternative visions of sustainable places. This paper discusses the implications of the competent nature of plural ecological design perspectives for architectural education, practice, and researches.

This study aimed to develop an optimal model of transportation for people with disabilities. To achieve this goal, powers of research and design should be involved, including CAD software. This paper investigates both: the concept of optimal model of transportation for people with disabilities (functional, ergonomic, constructive, technological and aesthetic solutions included); and its implementation as a fully-fledged 3D-model designed in SolidWorks environment. The optimal model of transportation is complex and consists of two objects. The first object is for indoors that is a wheelchair, the second one is for street driving that is an individual vehicle. The optimal model of transportation is universal and multifunctional, which have become possible with parametric feature-based approach utilized in SolidWorks.
