As the properties of living space and objects change in the digital era, furniture is also expected to change. This study starts from the question of such inclination that the digital innovation drives territories among products into the ambiguous, then tries to trace the variation of meaning against the furniture. Based on this possibility these functions, this research aims, to find out the digital functions which is preferred to be integrated with the furniture for the users of the residential space and the interface design aspects, which are considered important. preliminary survey using university students was done to extract the possible digital functions for convergence. The respondents were married women in their 20s and 30s who filled out the surveys on the internet. As a result, the specific digital convergence functions for both living and kitchen space were Identified. As major important expects for them were found functionality and controllability. Thus furniture design will expand to a concept which designs a new way of life.

This study aim to clarify the way of spatial composition of Tongdo Temple by diachronic analysis. The way of spatial composition was clarified through the analysis of built in architectural system in three periods. The result are as follows; 1. Spatial composition of Tongdo temple was changed in three period that it were establishment period, 1300s, and 1700s by the transition of meaning structure occurring the transition of spatial composition. 2. It was found out that the wat of spatial composition was three through the diachronic analysis the transition of spatial composition in Tongdo temple. 3. Juxtaposition as a way of spatial composition found out through the diachronic analysis is equivalent articulation of three sections; an upper, a middle, and a lower section and polyaxis or polycore in the each sections. Fusion is heterogenetic minglement mingling different kind of buildings and conjugation conjugating different kind of decorations. And accumulation of layer is mutilayer laying different time of layer and multi aspect aligning different kind of aspects since the temple's establishment.

Micro machining can manufacture complex shapes with high accuracy. Especially, this enables wide application of micro technology in various fields. For example, micro channels allow fluid transfer, which is a widely used technology. Therefore, liquidity research of flow in micro channels and micro channel manufacturing with use of various materials and cutting conditions has very important meaning. In this study, to find out correlation between fluid velocity in micro channels and surface roughness, we manufactured micro channels using micro end-mill and dropped ethanol into micro channels. We compared several surface roughness and fluid velocity in micro channels that were created by various processing conditions. Finally, we found out relationship between fluid velocity and surface roughness in micro channels of different materials.

A linear quantitative structure-property relationship (QSPR) model is presented for the prediction of rejection in permeation through membrane. The model was produced by using the multiple linear regression (MLR) technique on the database consisting of retention data of 25 pesticides in 4 different membrane separation experiments. Among the 3224 different physicochemical, topological and structural descriptors that were considered as inputs to the model only 50 were selected using several criteria of elimination. The physical meaning of chosen descriptor is discussed in detail. The accuracy of the proposed MLR models is illustrated using the following evaluation techniques: leave-one-out cross validation procedure, leave-many-out cross validation procedure and Y-randomization.

A basic assumption in the current design and analysis of reinforced concrete(RC) box structures, which are constructed by the open cut and fill method, is that the displacements and forces are uniform in the longitudinal direction of the structure. The solution may be therefore obtatined from the analysis of a unit wide strip along longitudinal axis. This strip is said to be in a plane strain condition, meaning that the out of plane deformations are vanished. The current design of box structure is carried out by the result of planar frame model for the sake of simplicity. The purpose of this study is to show more rational design method of box culverts considering a rigid zone of corner joints. The current analysis of box structures will be compared with the plane strain analysis as well as 3-d shell model. Reinforcement quantity is also determined to resist the tensile force in corner joints of box structures using strut-tie model which has been developed through the elastic analysis.

The 2015 revised mathematics curriculum had newly introduced the term 'process-focused assessment'. The official document, however, did not offer an explicit definition of the new term, but only by virtue of narrative. This has encouraged practitioners and researchers to figure out themselves what it is and how it differs from those in use, formative assessment and performance assessment in particular, in use. In consequence, many versions of interpretation, all of which are not necessarily consistent, have been developed and implemented in schools, This, in turn, still has created a chaotic situation carrying out the process-focused assessment. This study attempted to make the meaning of the process-focused assessment more explicit by conducting a comprehensive review of the related literature, for implementing it in its intended way.

In this study, it was carried out to characterize the figures of landform of Yong-San, called dragon mountain implied indentity and emblem of local landscape by analyzing palce name extracted from four county in Kyongsang Nam-Do. The figures of landform of Yong-San was characterized and divided into three types, called as Waryong lying dragon), Banryong(dragon lying in a coil), Yongdu(dragon's crown). And the spatial characterstics of three types of landform were analyzed. Furthermore, it was investigated the development of outlines of characteristic landform recognoxed as a Yong-San and figured out the structure of landform which was easily recognized. According to the results, the outlines and the spatial structure of landform recognized as a Yong-San including a symbolic meaning can be used as a standard of judgement if an area should be reserved for the efficient conduct of regional plan.

Purpose: To find out the appropriate probability distribution of credit card usage behavior by considering the relationship among income, expenditure and credit card usage amount. Such relationship is enabled by Korea's especially high penetration of credit card. Method: Goodness-of-fit test and effect size statistic W were used to identify the distribution of income and credit card usage amount. A simulation model is introduced to generate the credit card transactions on individual user level. Result: The three data sets for testing had either passed the chi-square test or showed low W values, meaning they follow the exponential distribution. And the exponential distribution turned out to fit the data sets well. The r values were very high. Conclusion: The credit card usage behavior, denoted as the counts of users by usage amount band, follows the exponential distribution. This distribution is easy to manipulate, has a variety of applications and generates important business implications.
