Removal independence is a translation of Arrow's axiom of independence of irrelevant alternatives for social welfare functions to an axiom about consensus functions involving n-trees. It is shown that a consensus function is removal independent if and only if it is expressible as th union of three types of functions.

According to the characteristics of salvo attack for the multiple flight vehicles (MFV), the design of cooperative guidance law can be converted into the consensus problem of multi-vehicle system through the concept of multi-agent cooperative control. The flight vehicles can be divided into leader and followers depending on different functions, and the flight conditions of leader are independent of the ones of followers. The consensus problem of leader-follower multi-vehicle system is researched by graph theory, and the consensus protocol is also presented. Meanwhile, the finite time guidance law is designed for the flight vehicles via the finite time control method, and the system stability is also analyzed. Whereby, the guidance law can guarantee the line of sight (LOS) angular rates converge to zero in finite time, and hence the cooperative attack of the MFV can be realized. The effectiveness of the designed cooperative guidance method is validated through the simulation with a stationary target and a moving target, respectively.

Transcription factors are proteins that bind specific sites or elements in regulatory regions of DNA, known as promoters or enhancers, where they control the transcription or expression of target genes. MEIS1 protein is a DNA-binding domain present in human transcription factors and plays important roles in various biological functions. The hydrogen exchange rate constants of the imino protons were determined for the wild-type containing the consensus DNA-binding site for the MEIS1 and those of the mutant DNA duplexes using NMR spectroscopy. The G2A-, A3G- and C4T-mutant DNA duplexes lead to clear changes in thermal stabilities of these four consensus base pairs. These unique dynamic features of the four base pairs in the consensus 5'-TGAC-3' sequence might play crucial roles in the effective DNA binding of the MEIS1 protein.

The problems to compute the distances or similarities of multiple strings have been vigorously studied in such diverse fields as pattern matching, web searching, bioinformatics, computer security, etc. One well-known method to compare multiple strings in the given set is finding a consensus string which is a representative of the given set. There are two objective functions that are frequently used to find a consensus string, one is the radius and the other is the consensus error. The radius of a string x with respect to a set S of strings is the smallest number r such that the distance between the string x and each string in S is at most r. A consensus string based on radius is a string that minimizes the radius with respect to a given set. The consensus error of a string with respect to a given set S is the sum of the distances between x and all the strings in S. A consensus string of S based on consensus error is a string that minimizes the consensus error with respect to S. In this paper, we show that the problem of finding a consensus string based on radius is NP-complete when the distance function is a metric.

Molecular docking is a critical event which mostly forms Van der waals complex in molecular recognition. Since the majority of developed drugs are small molecules, docking them into proteins has been a prime concern in drug discovery community. Since the binding pose space is too vast to cover completely, many search algorithms such as genetic algorithm, Monte Carlo, simulated annealing, distance geometry have been developed. Proper evaluation of the quality of binding is an essential problem. Scoring functions derived from force fields handle the ligand binding prediction with the use of potential energies and sometimes in combination with solvation and entropy contributions. Knowledge-based scoring functions are based on atom pair potentials derived from structural databases. Forces and potentials are collected from known protein-ligand complexes to get a score for their binding affinities (e.g. PME). Empirical scoring functions are derived from training sets of protein-ligand complexes with determined affinity data. Because non of any single scoring function performs generally better than others, some other approaches have been tried. Although numerous scoring functions have been developed to locate the correct binding poses, it still remains a major hurdle to derive an accurate scoring function for general targets. Recently, consensus scoring functions and target specific scoring functions have been studied to overcome the current limitations.

$\sigma^{B}$ plays an important role in both osmoprotection and proper differentiation in Streptomyces coelicolor A3(2). We searched for candidate members of the $\sigma^{B}$ regulon from the genome database, using the consensus promoter sequence (GNNTN$_{14-16}$GGGTAC/T). The list consists of l15 genes, and includes all the known $\sigma^{B}$ target genes and many other genes whose functions are related to stress protection and dif-ferentiation.

In this investigation we report our search for the presence of Leucine Rich Repeats (LRRs) in various Bacillus thuringiensis (Bt) sub species. Leucine rich repeats are short sequence motifs present in some proteins. The consensus sequence corresponding to the LRR was present in Crystal proteins of Bacillus thuringiensis sub species. This LRR sequence has been predicted to be involved in proteinprotein interactions or receptor binding functions, hence the importance of this study.

Securing food safety, natural and social environmental protection, and activation of rural communities are some of challenging tasks for the 21st century. National consensus on agriculture as a basic and public industry would be needed to solve these challenging tasks. Agricultural policy and extension education should be focused on encouraging farmers to achieve better production and management by developing their motivation and ability. Systematic and organizational efforts to make a better environment for farming and farm management should be the major target of agricultural policy and extension services in the future. To meet changing needs of farmer, agricultural extension services should change programs, functions, information sources, and methods of delivery to adopt experiential learning for farmers. Functions for consultation, suggestion and organization should be extended and advisory services for farmers should be emphasized by providing extension education.

Although many local governments are supporting the environment-friendly regional agriculture(hereafter EFRA), the EFRA is not wildly extended since the marketing and consumption of the environment-friendly agricultural products are still limited. This study aims at finding out the new development source of Korean agriculture and strategies for establishing regional agriculture. For these purposes, Sunchon-si cases of EFAP development are introduced and the functions and roles of bodies in charge of regional agriculture are looked over. In order to establish the EFRA, production, processing and consumption needs to be intimately linked all together. As preconditions for developing the EFRA, four points should be satisfied. Firstly, production organizations need to be built and stabilized for developing the EFRA and consumers' organizations and partnership are to be formed. Secondly, the government should support for building consumers' organization. Thirdly, social consensus for developing the EFRA needs to be formed. And finally with the appropriate local and central governmental support the partnership among producers, consumers, and government should be formed.

As generalization of using PC and the Internet information technology (IT) users in organizations are not passive clients but active producers of information services. One of the reasons for the change of users' role is social interactions with other users and IT department staffs. That is, users can find and develop new functions and usefulness of IT, especially, Web-based ones through communication with other users or IT department staffs. The objective of this study is to investigate the relationship between IT department service quality and social interactions with other users. For this purpose, we suggest a research model based on adaptive structuration theory (AST), which is to explain the changes in social structure (rules and resources) of IT by social interactions, as well as service quality theory. Our model's exogenous variable is service quality which is a second-order factor consisting of reliability, responsiveness, assurance, and empathy. As endogenous variables, we adopt two variables for appropriateness of using IT, faithfulness of appropriation and consensus on appropriation. Finally, dependent variables of ow model are usefulness and ease of use which can be considered as attitude on IT as well as other variables for appropriateness. For empirical test our model is applied to users of groupware and ERP in organizations and analyzed by partial least square. In result, all hypotheses suggested in our model are supported statistically.
