Due to the expensiveness of IKONOS Pro and Precision Products, it is attractive to use the low-cost IKONOS Geo Product with vendor-provided RPCs to produce highly accurate mapping products. The imaging geometry of IKONOS high-resolution imagery is described by RFs instead of rigorous sensor models. This paper presents four different models defined respectively in object space and image space to improve the accuracies of the RF-derived ground coordinates. The four models include the offset model, the scale & offset model, the affine model and the 2nd-order polynomial model. Different configurations of ground control points (GCPs) are carefully examined to evaluate the effect of the GCPs arrangement on the accuracy of ground coordinates. The experiment also evaluates the effect of different cartographic parameters such as the number location, and accuracy of GCPs on the accuracy of geopositioning.

Nucleotide sequence of Brevibacterium flavum ptsG gene capable of complementing Escherichia coli ZSC113 mutations defective to glucose permease activity of phosphotransferase system was completely determined, and the gene product was compared with other glucose-specific enzyme II ($EII^{Glc}$). A ptsG gene of B. flavum consisted of open reading frame of 2,025 nucleotides putatively encoding polypeptide of 675 amino acid residues and TAA stop codon. Deduced amino acid sequence of B. flavum ($EII^{Glc}$) had high homology with ($EIIs^{Glc}$) of Corynebacterium glutamicum, C. efficiens, and B. lactofermentum. Arrangement of structural domains, IIBCA, of B. flanum ($EII^{Glc}$) protein was identical to that of EIIs belonging to glucose-phosphotransferase system.

In retailing, it seems very important to examine how consumers perceive in store design factors such as instore space for walking, product arrangement styles, instore display types, window sizes, and possibly others. Furthermore, consumers perceptions of various designs would be differentiated by consumers shopping patterns such as actual shopping versus window shopping. This article empirically investigates how various desings create different consumer reactions measured by consumer mood and store image depending on the types of consumer shopping. It was found that design factors such as open, focused, and big would create better consumer mood and consumer perceptions of store image than closed, unfocused, and small. Another finding was that consumer perceptions would interact with consumer shopping patterns. Based on the research findings, some implications are discussed in the article.

'Enhanced Cooperation', which was the mandate of Tunis Agenda in 2005, was the product of political compromise after failing to reach a consensus on global internet governance mechanism. In 2012, UN General Assembly decided to establish CSTD 'Working Group on Enhanced Cooperation (WGEC)' to find out what could and should be done to implement the Tunis Agenda. After a first meeting, WGEC sent out a questionnaire to collect extensive opinions from internet communities. Replies to the questionnaire showed a broad spectrum of perspectives on the problem of existing internet governance arrangement and how to improve it. This article analysed different perspectives, based on replies, especially regarding the concept and implementation of the Tunis Agenda, public policy issue and possible mechanisms, and the role of stakeholders including government. The recommendation of WGEC will be submitted to UN GA passing through CSTD and ECOSOC, in 2014, which is expected to have great impact on the future of internet governance.

Al-MCM-48 molecular sieves (Si/Al = 25, 50, 75 and 100) were synthesized hydrothermally using cetyltrimethyl ammonium bromide as the structure directing template. The orderly arrangement of mesopores was evident from the low angle X-ray diffraction patterns and TEM images. The catalytic performance was evaluated in the vapour phase isopropylation of phenol with isopropyl acetate. Phenol conversion decreased with increase in the Si/Al ratio of the catalysts. The major reaction product was 4-isopropyl phenol (selectivity: 78%). Delocalization of phenolic oxygen electron pair over the aromatic ring promoted para-selective alkylation. Such delocalization could be aided by the hydrophilic surface of the molecular sieves. Though ester was used as the alkylating agent, phenyl isopropyl ether was not formed

FRC(Frame Rate Control) has been applied to the monitor and TV product as part of cost-saving in many flat panel display manufacturers. As FRC can represent the same number of gray scale level with bits of a smaller amount than bits of the input image data, it is widely used. However, FRC causes visual artifacts by using repeatedly pre-designed the FRC unit size of block pattern in display devices. Therefore, this paper analyzes the cause of the visual artifacts. And in order to improve them, it proposed the pattern arrangement of FRC unit blocks through frame rolling method as analytic solution for the first time. So, we could embody causes of FRC noise. Using the proposed structure, more robust pattern to FRC noise will be designed.

The psychophysical magnitude estimation thechnique can provide a useful tool for determining the best design features of a product in terms of user preference, especially when it is difficult or almost impossible to obtain objective and quantitative data on the user performance. In this research, several interior design features of a high speed train such as arrangement of passenger seats, and availability of interior facilities were examined quantitatively to provide interior design recommendations for the high speed train. A train simulator was built to provide a realistic interior enviror enviroment of the high speed train, and individual design features were manipulated by using a three-factor within-subject experimental design. At the same time, a psychophysical scale of verbal descriptors ranging from "extremly like" to "extremly dislike" was developed to explain the magnitude estimates of the design features in ordinary language.n ordinary language.

In retailing, it is very important to examine how consumers perceive and react to in-store design factors such as in-store space for walking, product arrangement styles, display types, and window sizes. Furthermore, consumers' perceptions to the various designs would be differentiated by consumers' shopping patterns such as actual shopping versus window shopping. This article investigates how various designs create different consumer reactions measured by consumer mood and store image depending on the types of consumer shopping (i.e. actual shopping vs. window shopping). It was found that design factors such as open, focused, and big created better consumer mood and consumer perception of store image than closed, unfocused, and small. Another finding is that consumer perceptions interact with consumer shopping patterns. Based on the research findings, managerial implications are also discussed

최근 상품의 특성을 고려하지 않은 박스 크기 선택과 박스 공간 내 비효율적인 상품 배치로 인하여 박스의 파손 문제가 지속적으로 제기되고 있다. 이는 적재하고자 하는 상품의 특성을 고려하지 않고 상품을 대략적으로 배치하기 때문이다. 따라서 본 논문에서는 면적과 무게와 같은 상품의 특성을 고려한 상품 배치 최적화 알고리즘을 제안하여 공간 배치의 비효율성 문제를 최소화하고자 한다. 제안한 상품 배치 최적화 알고리즘은 검색 트리 (search tree)와 상품 특성 기반 평가 함수(evaluation function)로 구성되어 있다. 상품 특성 기반 평가 함수는 면적, 무게 및 바닥에 닿는 면적을 고려하여 설계되었다.
