The filial piety culture represented by Cao-e was regarded as moral rule mechanism in order to maintain patriarchal system and property relations in ancient China as an agricultural society. Exactly, In the process of Cao-e's story spreading, oral inheritance and literature processing have a relation of learning and penetration each other in order to beautify, deify, systematic stories. This is expression of human being's thought method of pursuing perfection. For instance, The traditional piety culture is increasingly weakened, that is why it is important to recognize the fundamental connotation behind the cultural identity in the modern society, to create the social foundation of Cao-e' filial piety cultural contents root, and to explore the core values of piety culture contains. Looking Cao-e' filial piety Culture and culture archetypes as study object, this article analyzes the spreading of Cao-e's story texts for understand the connection between literature processing and image formation from aspect of Cao-e deification.

DC microgrids are considered as prospective systems because of their easy connection of distributed energy resources (DERs) and electric vehicles (EVs), reduction of conversion loss between dc output sources and loads, lack of reactive power issues, etc. These features make them very suitable for future industrial and commercial buildings' power systems. In addition, the bipolar-type dc system structure is more popular, because it provides two voltage levels for different power converters and loads. To keep voltage balanced in such a dc system, a bidirectional dual buck-boost voltage balancer with direct coupling is introduced based on P-cell and N-cell concepts. This results in greatly enhanced system reliability thanks to no shoot-through problems and lower switching losses with the help of power MOSFETs. In order to increase system efficiency and reliability, a novel burst-mode control strategy is proposed for the dual buck-boost voltage balancer. The basic operating principle, the current relations, and a small-signal model of the voltage balancer are analyzed under the burst-mode control scheme in detail. Finally, simulation experiments are performed and a laboratory unit with a 5kW unbalanced ability is constructed to verify the viability of the bidirectional dual buck-boost voltage balancer under the proposed burst-mode control scheme in low-voltage bipolar-type dc microgrids.

$\ulcorner$The South-North Joint Declaration$\lrcorner$ of June 15, 2000 made by President Kim Dae Jung and National Defense Committee Chairman Kim Jong Il will contribute to the activation of economic exchange between south and north Korea. To realize the fundamental spirit of the South-North Joint Declaration, the authorities concerned of south and north Korea have reached an agreement titled $\ulcorner$Agreement on Settlement Procedure of Commercial Disputes$\lrcorner$ last December. In this connection, a speedy and reasonable settlement of commercial disputes arising therefrom is becoming a problem of vital importance between south and north Korea. Also, south and north arbitral institutions have to consider a possible arbitration agreement carefully to solve the disputes systematically under the Agreement, which will serve as an example for similar arrangements and possible harmonization in East-West commercial relations. A variety of dispute settlements including friendly consultations, conciliation and arbitration will be used more frequently within the framework of the bilateral agreements of governmental or non-governmental level which have been concluded in the past between socialist and capitalistic economy countries. There is a growing tendency that East-West trade parties recognize and accept the UNCITRAL Arbitration Rules in their contracts. So it is advisable to use the UNCITRAL Rules in arbitrations of south and north Korea in case that the interested parties fail to agree on applicable rules. Finally it should be noted that pre-arbitral settlement called ‘joint conciliation’ should be reflected in the settlement mechanism of commercial disputes between south and north Korean parties as proved to be successful between the U.S. and China trade in the past.

In this study, the slip behavior of high-tension bolted joints subjected to compression force is investigated through 3D finite element analysis and experiments. The relation with sliding load, bolt deformation, and failure load are studied with the metal thickness affecting the bolted joint. The post-sliding behavior considering bolt stiffness is presented and compared with the results by finite element and experiments. The finite element model is constructed by solid elements in ABAQUS, in consideration of all the friction effects between metal plates and bolts. The stress-strain relations in the literature are used, and the sliding displacements and axial stresses around the bolt connection are investigated. The flexural buckling of species happened when the plate thickness is less than the bolt diameter. However, the shear failures of bolt occurred in the opposite case.

PURPOSE. Implant site preparation may be adjusted to achieve the maximum possible primary stability. The aim of this investigation was to study the relation among bone-to-implant contact at insertion, bone density, and implant primary stability intra-operatively measured by a torque-measuring implant motor, when implant sites were undersized or tapped. MATERIALS AND METHODS. Undersized (n=14), standard (n=13), and tapped (n=13) implant sites were prepared on 9 segments of bovine ribs. After measuring bone density using the implant motor, 40 implants were placed, and their primary stability assessed by measuring the integral of the torque-depth insertion curve. Bovine ribs were then processed histologically, the bone-to-implant contact measured and statistically correlated to bone density and the integral. RESULTS. Bone-to-implant contact and the integral of the torque-depth curve were significantly greater for undersized sites than tapped sites. Moreover, a correlation between bone to implant contact, the integral and bone density was found under all preparation conditions. The slope of the bone-to-implant/density and integral/density lines was significantly greater for undersized sites, while those corresponding to standard prepared and tapped sites did not differ significantly. CONCLUSION. The integral of the torque-depth curve provided reliable information about bone-to-implant contact and primary implant stability even in tapped or undersized sites. The linear relations found among the parameters suggests a connection between extent and modality of undersizing and the corresponding increase of the integral and, consequently, of primary stability. These results might help the physician determine the extent of undersizing needed to achieve the proper implant primary stability, according to the planned loading protocol.

Generally the connection of structural members is assumed as hinge, rigid and semi-rigid connections. The exact tangent stiffness matrix of a semi-rigid frame element is newly derived using the stability functions considering shear deformations. Also, linearized elastic- and geometric-stiffness matrices of shear deformable semi-rigid frame are newly proposed. For the exact stiffness matrix, an accurate displacement field is introduced by equilibrium equation for beam-column under the bending and the axial forces. Also, stability functions considering sway deformation and force-displacement relations with elastic rotational spring on ends are defined. In order to illustrate the accuracy of this study, various numerical examples are presented and compared with other researcher's results. Lastly, shear deformation and semi-rigid effects on buckling behaviors of structure are parametrically investigated.

Elementary schools and middle schools currently manage their student data by using the education administration system. One of its sub-systems called 'the academic affairs support system' is especially dedicated to handle school and academic affairs data. By allowing simple data search and statistical data calculations, it helps teachers easily integrate and manage education information resources. However, it is not easy for teachers to analyze the correlations among student data. In this paper, we showed by examples that a lot of meaningful information can be extracted by analyzing the relations among student data. Based on the results, we designed and implemented SIMS as a tool to provide teachers with such services. SIMS makes use of Association Rules for data correlation analyses. SIMS can be used in connection with the academic affairs support system, and is much easier to use than previously developed commercial products for similar services.

The purpose of this study was to analyse the relations among the residents' characteristics, the policy of the facility, and the physical characteristics of activity areas, and to understand the elements for the lively use of activity areas in the elderly nursing facilities. The results of the study are as follows: First, there was a relationship between the characteristics of semi-public activity areas and the residents' management-control policy. The facilities having semi-public areas of living room type showed more flexibility in time and place and more respects for the residents. Second, the activity areas of connection type were much more used than the compartment type, especially in the facilities having more residents incapable of walking. On the other hand, the facilities having high control for the residents showed high using rate in public activity areas, and all those did not have semi-public areas or showed low using rate in there. Third, in the analysis of the relationship between the physical characteristics and the using rate of activity areas, the public activity areas having compartment type in the spatial composition and hall as a form were likely to have multiple usages. On the whole, the various form of activity areas, the area per residents, openness, accessibility and centrality were having interactions each other for high using rate in activity areas. Especially, many stimulations and the furniture arrangements that were good for the residents' interactions had a function of compensation for the poor physical characteristics of activity areas. This study investigated only the using rates to understand the lively use of the space. For the future study, it is suggested that the detail using behavior of the residents should be examined to understand the influential elements.

The purpose of this study was to identify the relations among questions level, questions process, and hesitation factor of questions. Data were collected from 174 students at a university in D city using structured questionnaire from September 9 to April 10 2015. It was analyzed with frequency analysis, descriptive statistics, t-test, ANOVA, and correlation analysis. As a result, the learners' questions are made from cognitive confusion, these questions led the students to ask a question actually. Also, this study confirmed that the learners' internal hesitation factors had negative correlation when the students asked a question in real situation. In order to improve the asking question we'll need to be generating a lot of questions to the student's inside and outside. We also need to develop appropriate teaching methods so that this can be perceived connection of cognitive confusion-having questions-asking questions.
