  • In order to accelerate the rate of consolidation settlement and gain a required shear strength for a given soft clay deposit, vertical drain method combined with a preloading technique has been widely applied. In this paper, a theory of axisymmetric nonlinear consolidation fer drainage-installed deposit, which considers secondary compression (or creep) during primary consolidation, as well as the variations of compressibility and permeability during the consolidation process, has been developed. A computer program named AXICON based on Hypothesis B fur the analysis of axisymmetric nonlinear consolidation was developed by adopting finite difference method. The results of AS(ICON were compared with Hansbo's solution based on Hypothesis A, as well as in-situ settlements and pore pressures measured in test embankment of Ska-Edeby. The results indicated that Hypothesis A usually underestimated the in-situ settlement and Hypothesis B was considered to be logically correct. It was also shown that one may able to appropriately predict the real in-situ behaviors using the proposed program.

  • This is an analysis of three hypotheses in the fields of Technology, Innovation, and Management (TIM) analyzing the journal of Jishu Jingji (Technology Economics) which is published by the Chinese Society of Techno-economics. The Jishu Jingji journal is similar to other Chinese journals in TIM as follows: First, it's short in length. Second, there are a few references and foreign references can be counted with fingers of one hand. Third, the journal's scope is similar to others in TIM such as technolog-firm-industry. The differences are as follows: First, they have more general topics on the firm and the economy than other journals in TIM. Second, technologies covered are those of existing industries and infrastructure rather than emerging technologies and industries. Third, editors rarely submit papers to the journal. Finally, the expertise of the editors is diverse which is similar to the scope of the journal. First proposed hypothesis on journals in TIM is that journals represent country specific characteristics over field specificities, and this view is widely accepted in China. Second hypothesis is that editors are representatives of authors, but this hypothesis is rejected, at least in this journal. Third hypothesis is that the composition of editors reflects the scope of journals, and this hypothesis is generally accepted.

  • This study explores the effects of spousal dissimilarity on marital stability among transnational couples in Korea. Utilizing micro-data from the 2009 Korean National Multi-culture Family Survey, this paper examines whether formation of transnational marriage generally involves positive assortative matching on age and education. Indices of age dissimilarity and educational dissimilarity are calculated for each country of origin of the foreign wife, and their relationships to the average duration of marriage are analyzed. This study also conducts a micro-level analysis of whether age and educational dissimilarity between spouses helps explain variations in marital duration and probability of getting divorced. Results show greater incidences of spousal dissimilarity in age and educational attainment among transnational couples, which supports the transnational openness hypothesis proposed in this paper. The extant hypothesis that spousal dissimilarity increases the risk of marital dissolution and shortens the duration of marriage is not found to fit transnational couples in Korea.

  • The object recognition mechanism of human being is not well understood yet. On research of animal experiment using an ape, however, neurons that respond to simple shape (e.g. circle, triangle, square and so on) were found. And Hypothesis has been set up as human being may recognize object as combination of such simple shapes. That mechanism is called Figure Alphabet Hypothesis, and those simple shapes are called Figure Alphabet. As one way to research object recognition algorithm, we focused attention to this Figure Alphabet Hypothesis. Getting idea from it, we proposed the feature extraction algorithm for object recognition. In this paper, we described recognition of binarized images of multifont alphabet characters by the recognition model which combined three-layered neural network in the feature extraction algorithm. First of all, we calculated the difference between the learning image data set and the template by the feature extraction algorithm. The computed finite difference is a feature quantity of the feature extraction algorithm. We had it input the feature quantity to the neural network model and learn by backpropagation (BP method). We had the recognition model recognize the unknown image data set and found the correct answer rate. To estimate the performance of the contriving recognition model, we had the unknown image data set recognized by a conventional neural network. As a result, the contriving recognition model showed a higher correct answer rate than a conventional neural network model. Therefore the validity of the contriving recognition model could be proved. We'll plan the research a recognition of natural image by the contriving recognition model in the future.
