The wedding seating problem(WSP) is to finding a minimum loss of guest relations(sit together preference) with restricted seats of a table for complex guest relation network. The WSP is NP-hard because of the algorithm that can be find the optimal solution within polynomial-time is unknown yet. Therefore we can't solve the WSP not computer-assisted programming but by hand. This paper suggests min-cut rule theory that the two guests with maximum preference can't separate in other two tables because this is not obtains minimum loss of preference. As a result of various experimental, this algorithm obtains proper seating chart meet to the seats of a table constraints.

In this study, thermally induced bifurcation buckling of shallow composite cylindrical panels reinforced with aligned single-walled carbon nanotubes is investigated. Distribution of carbon nanotubes across the thickness of the cylindrical panel as reinforcements may be either uniform or functionally graded. Thermo-mechanical properties of the matrix and reinforcements are considered to be temperature dependent. Properties of the cylindrical panel are obtained using a refined micromechanical approach which introduces the auxiliary parameters into the rule of mixtures. The governing equations are obtained by using the static version of the Hamilton principle based on the first-order shear deformation theory and considering the linear strain-displacement relation. An energy-based Ritz method and an iterative process are used to obtain the critical buckling temperature of composite cylindrical panel with temperature dependent material properties. In addition, the effect of various parameters such as the boundary conditions, different geometrical conditions, distribution pattern of CNTs across the thickness and their volume fraction are studied on the critical buckling temperature and buckled pattern of cylindrical panels. It is shown that FG-X type of CNT dispersion is the most influential type in thermal stability.

The present study aimed to find a way to create forms that can simultaneously meet several architectural requirements by applying generative design methods specifically focused on cellular automata. In other words, it is tried to find various forms of architecture that all have common features. Because of the useful features of cellular automata, we decided to use it to generate various forms, but make a relation between the discrete nature of cellular automata and the continuous nature of architecture, was the major problem of our project. To achieve this goal, three consecutive stages were designed. In the first stage, independent variables including the location of the building, the height of the building, and the building area were considered as the inputs of the model. In the second stage, after locating the building, the building's main shell was designed as a hidden geometry for the cellular automata and then the cellular automata were determined based on this shell. The main result of this research is establishing a logical relationship between the discrete geometry of the cellular automata and the continuous search space such that it creates various optimized forms. Although we specify the site plan of this project at Iran-Tehran, this research can be generalized to various design sites as well as different projects, allowing the architectsto alter the cell dimensions, cell density, etc., based on their opinion and project needs.

In spite of the ethics of sangsaeng is based on Daesoon thoughts, we can regard it as a moral theory independent on religion. Like other reasonable moral theories, It has three levels, moral standard, moral rules and moral acts or judgements. Sangsaeng is moral standard in the ethics of sangsaeng. moral rules are derived from it and could justify many particular moral judgements and acts. The ethics of sangsaeng belongs to metaphysical ethics and holistic ethics because it is derived holistic, sangsaeng's world view of Daesoon thoughts. The ethics of sangsaeng, first of all, extends the realm of moral community to all beings of world. Therefore it might works well on as a solution for environmental problem recently issued. Secondly, because beings are fundamentally all equal in holistic world, the principle of equality is basic principle in the ethics of sangsaeng. Finally, in relation to the principle of equality, the ethics of sangsaeng needs 'Haewon' as the first moral rule because it is a practical method for solution to various social inequality - racism, sexism, regionalism and so on.

For the purpose of building domain ontology, this paper proposes a methodology for building core ontology first, and then enriching the core ontology with the concepts and relations in the domain thesaurus. First, the top-level concept taxonomy of the core ontology is built using domain dictionary and general domain thesaurus. Then, the concepts of the domain thesaurus are classified into top-level concepts in the core ontology, and relations between broader terms (BT) - narrower terms (NT) and related terms (RT) are classified into semantic relations defined for the core ontology. To classify concepts, a two-step approach is adopted, in which a frequency-based approach is complemented with a similarity-based approach. To classify relations, two techniques are applied: (i) for the case of insufficient training data, a rule-based module is for identifying isa relation out of non-isa ones; a pattern-based approach is for classifying non-taxonomic semantic relations from non-isa. (ii) For the case of sufficient training data, a maximum-entropy model is adopted in the feature-based classification, where k-NN approach is for noisy filtering of training data. A series of experiments show that performances of the proposed systems are quite promising and comparable to judgments by human experts.

I have investigated questionaire concerning to the view of worth and construction of consciousness as to boarding system collegian who will employed in fisheries and maritime industries. The results were as follows; It appeared 38.9% that most collegian had a firm subjectivity about enrolled motive, selection of department, they had selected department according to the neighborhood recommendation, own squired score rather than the adaption and prospection, also it was appeared 55% that they had not satisfied with attending to their college, accordingly, the effectiveness of education were demolished in such aspects. It was appeared 74.3% that the education of fisheries and maritime college were divided into theory and practice pertinently also, 77.1% that modulate both technical education and human like education but as a general rule, the education of ocean going liscensed officer was appeared 7.1% only so that, the reformation of the curriculum and contents of education would be needed. As to the relation between professors and collegian, it was appeared 38.4% that well understanding professor, 18.1% that well teaching professor, 13.3% that they having humanlish relation with professor, 30.6% that they will benefit to vocational selection. consequently, the professor have to brings up the harmony on dint of education and industries. The things which collegian think to be worth were 43.6%, intercourse of friend 30.3%, circle activity. 6.6% listening lecture, also, the leisure activity after school were 74.7% with friends. 16.4% alone. consequently, the professor has to guide of leisure activity after lesson. most collegian has a good relationship with their parent(91.6%) but the respond with bad relationship was 8.4%. The most serious agony which collegian think about is vocational problems (48.9%), the other sex problem(22.5%). The objects consult with agony was aquaintance(54.9%). The parent(5.1%), professors(2.3%), the collegian who did not consult with agony was 20.9%. The parents and the professor is not object consult with their agony. so that, the professors has to strengthen the education according to the human nature. As to job after graduation of such college, collegian who wish to be taken job on the fisheries and maritime industry were 50.5%, on the contrary, the collegian who wish to be taken a job no relation with his major subjects was 29.1% especially, the collegian who want to be embarked was 26.3% (fisheries 23.3%, maritime 30.5%). so that, we must adopt the counter plan for the globalization and effective investment on the fisheries and maritime college.

We have investigated the effect on inducing substate(s) of positively charged residues replaced in position 172 of the second transmembrane domain in murine inward rectifier potassium channels, formed by stable or transient transfection of Kir2.1 gene in MEL or CHO cells. Single channel recordings were obtained from either cell-attached patches or inside-out patches excised into solution containing 10 mM EDTA to rule out the effect of $Mg^{2+}$ on the channel gating. The substate(s) could be recorded with all mutants D172H, D172K and D172R. The unitary current-voltage (I-V) relation was not linear with D172H at $pH_i$ 6.3, whereas the unitary I-V relation was linear at $pH_i$ 8.0. The relative occupancy at $S_{LC}$ was increased from 0.018 at $pH_i$ 8.0 to 0.45 at $pH_i$ 5.5. In H-N dimer, that was increased from 0.016 at $pH_i$ 8.0 to 0.23 at $pH_i$ 5.5. The larger the size of the side chain or $pK_a$ with mutants (D172H, D172K and D172R), the more frequent the transitions between the fully open state and substate within an opening. The conductance of the substate also depended upon the pKa or the size of the side chain. The relative occupancy at substate $S_{LC}$ with monomer D172K (0.50) was less than that in K-H dimer (0.83). However, the relative occupancy at substate with D172R (0.79) was similar to that with R-N dimer (0.82). In the contrary to ROMK1, positive charge as well as negative charge in position 172 can induce the substate rather than block the pore in murine Kir2.1. The single channel properties of the mutant, that is, unitary I-V relation, the voltage dependence of the mean open time and relative occupancy of the substates and the increased latency to the first opening, explain the intrinsic gating observed in whole cell recordings.

While recommender systems were used by a few E-commerce sites former days, they are now becoming serious business tools that are re-shaping the world of I-commerce. And collaborative filtering has been a very successful recommendation technique in both research and practice. But there are two problems in personalized recommender systems, it is First-Rating problem and Sparsity problem. In this paper, we solve these problems using the associative relation clustering and “Lift” of association rules. We produce “Lift” between items using user's rating data. And we apply Threshold by -cut to the association between items. To make an efficiency of associative relation cluster higher, we use not only the existing Hypergraph Clique Clustering algorithm but also the suggested Split Cluster method. If the cluster is completed, we calculate a similarity iten in each inner cluster. And the index is saved in the database for the fast access. We apply the creating index to predict the preference for new items. To estimate the Performance, the suggested method is compared with existing collaborative filtering techniques. As a result, the proposed method is efficient for improving the accuracy of prediction through solving problems of existing collaborative filtering techniques.

The king-vassal-subject relation in neo-confucianism can be elucidated in their status context as well as in their communicative context. In their status context, there are two aspects of power such as sovereignty and rule. Chu-zhi thinks that subjects are nobler than king in the aspect of sovereignty, but the relation is reversed in the aspect of ruling power. These two relaitions are not contradictory, but compatible. When ruling power operates, he thinks, king, vassals and word-watching officials(諫官) must check each other. In their communicative context, there are theories of sympathy and public discourse. Sympathy consists of moral sympathy through virtue politics and emotional sympathy through enjoying together. Chu-zhi finds a theoretical basis of public discourse in the place where heavenly principle meets with human mind. Public discourse is to search for common good. Institutional arrangements for public discourse are the official's rights to open and free speech. He thinks that word-watching officials must be speech leaders.

The rule of warranty in English insurance law was established in the second part of the $18^{th}$ century by Lord Mansfield, who laid the foundations of the modern English law of insurance contract and developed very different rule of insurance law, especially in the field of warranty. At the time of Lord Mansfield, warranty, that is, the promise given by the assured, played an important role for the insurer to assess the scope of the risk. Legal environments, however, have changed since the age of Lord Mansfield. English and Scottish Commissions proposed very dramatic reform of law in the field of warranty law to reflect the changes of legal environment through the Insurance Act 2016. This article intends to consider the legal implications through the comparative analysis between the new regime of warranty in the Insurance Act 2015 and MIA 1906. The major changes in the Insurance Act 2015 are summarized as following. First, Basis of the contract clauses in non-consumer insurance contracts should be of no effect and representations should not be capable of being converted into warranties by means of a policy term or statement on the proposal form. This requirement should not be capable of being avoided by the use of a contract term and the arrangement of contracting out by parties should be of no effect. Secondly, The existing remedy for breach of warranty, that is, automatic discharge of the insurer's liability, should be removed. Instead, the insurer's libility should be suspended from the point of breach of warranty and reattach if and when a breach of warranty has been remedies. Thirdly, A breach of warranty should genally be regarded as remedied where the insured ceases to be in breach of it. In the other hand, for time-specific warranties which apply at or by an ascertainable time, a breach should be regarded as remedies, if the risk to which the warranty relates later, becomes essentially the same as that originally contemplated by the parties. Fourthly, where a term of an insurance contract relates to a particular kind of loss, or loss at a particular location/time, the breach of that term should only give the remedy in relation to loss of that particular kind of loss, or at a particular location/time. Finally, whether a term of an insurance contrat relates to loss of a particular kind of at a particular location/time should be determined objectively, based on whether compliance with that ther would tend to reduce the risk of the occurrence of that category of loss.
