Intelligent resilience of cementitious materials for marine infrastructures
N. Han 한양대학교 세라믹연구소 2015 Journal of Ceramic Processing Research Vol.16 No.S1
In this paper, a novel intelligent resilience system of cementitious materials for marine infrastructures developed recently at Shenzhen University is introduced. The aim of this system is to provide intelligent resilience against attacks of the marine environment on infrastructures made of cement-based materials, resulting in infrastructures with durability properties that far exceed those of conventional ones. Starting from the principles of intelligent resilience, the logic line of development of such a system is followed. Fundamental terms related to the resilience concept are discussed. On-going researches on material systems, design procedures and numerical models will be highlighted. The major challenges and further development concerning the intelligent resilience in cementitious materials will be addressed.
변형 · 초월과 대상관계 이론 : 기독상담적 연계와 해석적 접근
조난숙 한성대학교 인문과학연구원 2010 소통과 인문학 Vol.11 No.-
When we consider Christian counseling, the understanding of transcendence is essential. In this paper, we define Christian counseling as a liberating process for the man and God. First, we review the concepts of transcendence related with transformation and claim that these two concepts are quite intrinsically connected. Since God in Christianity is the transcendental object, this thought naturally leads to search some integration with object relation theory. Here, we include Kohut's self psychology in the realm of object relation theory. Some main concepts as transference, true-false self, transitional object and self object are considered with respect to the concept of transformation and transcendence in the view of Christian counseling.

Currently, the Social Sciences and Humanities (SSH) has become the field of global research. In Vietnam, the demand for the development of science and technology to national development and integration has become a pressing demand. Therefore, for a long time, almost all the concerns of the society towards the Science and Technology, meanwhile, sector of SSH were not paid due attention and proper investment. This problem has led to a worrying situation that is the Vietnamese Social sciences and Humanities are “lagging behind” in comparison with the countries in the world. The share of SSH articles published is very limited in international journals. Through understanding the reality of SSH research in Vietnam and the situation of SSH research in the world, the article suggested some solutions to in order to promote social sciences and Humanities research, to the SSH in Vietnam to strong development, towards integration and globalization. The solutions focus on the following issues: Building a Strategic Human Resources, Research Orientation and Planning, Promoting International research cooperation, Developing investment funds for research and Changing the form of grants, evaluate of research results.

In this paper, we investigate an initial boundary value problem for a nonlinear pseudoparabolic equation. At first, by applying the Faedo-Galerkin, we prove local existence and uniqueness results. Next, by constructing Lyapunov functional, we establish a sufficient condition to obtain the global existence and exponential decay of weak solutions.

Skin burn is one of the major causes of morbidity and mortality in burn patients due to its susceptibility to infection. The disruption of the epidermal barrier, combined with the denaturation of proteins and lipids, provides a fertile environment that is rich in bacterial nutrients for microbial growth, making it significantly prone to infection. This study aimed to formulate a thermoresponsive hydrogel containing silver nanoparticles (300 ppm), oligo chitosan 2%, and curcumin (0.1%) in the polymer pluronic F127 matrix with a final concentration of 13% to effectively promote the healing of skin wounds. The prepared thermoresponsive hydrogel was investigated for its physical and chemical stability, gelation temperature, and chemical composition. In addition to in vitro antibacterial activity against Staphylococcus aureus found in burn infections, in vivo burn healing and antibacterial activities were also investigated and compared with those of a commercial product using burn-induced infected wounds in mice. The formulation showed antibacterial activity with effective values for wound healing properties, as shown in vivo and by histopathological studies. This study also demonstrates that the thermoresponsive hydrogel was successful as an antibacterial and burned wound-healing transdermal drug delivery system.
Kernel Fisher Discriminant Analysis for Indoor Localization
Nhan V. T. Ngo,Kyung Yong Park,Jeong G. Kim 한국인터넷방송통신학회 2015 Journal of Advanced Smart Convergence Vol.4 No.2
In this paper we introduce Kernel Fisher Discriminant Analysis (KFDA) to transform our database of received signal strength (RSS) measurements into a smaller dimension space to maximize the difference between reference points (RP) as possible. By KFDA, we can efficiently utilize RSS data than other method so that we can achieve a better performance.
Log-likelihood Ratio Optimal Quantizer for Cooperative Spectrum Sensing in Cognitive Radio
Nhan Nguyen-Thanh,Insoo Koo IEEE 2011 IEEE communications letters Vol.15 No.3
<P>In order to reduce the bandwidth requirement for reporting channel, the quantization of sensing data's log-likelihood ratio (LLR) in cooperative spectrum sensing is considered. A well-preserved quantizer which minimizes mean square error of the sensing data's LLR at quantizer output is achieved by applying the well-known Lloyd-Max quantization algorithm. The probability density function of the LLR of the sensing information is also formulated for designing the quantizer. Simulation results reveal that the proposed quantizer provides the same sensing performance of the original LLR test with only few quantization bits.</P>
