Over the course of time, changes occur in family composition and members, and such changes impact housing life as well. In contrast to shared housing structures such as apartments, detached houses show a greater variety of changes to interior spaces such as family composition, rural area, natural environment, and modernization. The purpose of this study is to examine the change and factors in interior spaces in detached houses of rural area. Out of 40 houses studied in a 1995 survey, 23 showed changes when studied again in 2015, and 13 were selected for final analysis. This study indicated that at the time of the survey in 1995, two aspects of change occurred which showed in interior space only and internalization through interior-specific additions and improvements. An analysis of interior changes demonstrated there was significant change in kitchens, multipurpose rooms, and other spaces focused on housework and homemaking. Internalization through interior-specific is showed in balcony. As family member is increasing, it is intended to be increasing size of interior space; however, it is showed to increase size of interior space in the step that family member is reducing. It is reason that more spaces are needed when their children whose the old are living in detached houses of rural area are visited.

Recently, SystemC is one among the language observed. In Industry, there are many the languages that use Verilog. But, unskillful SystemC users must learn SystemC for conversion that from Verilog to SystemC and need time and effort for this. By these reason, feel necessity of easy and efficient conversion. This paper argues efficient methodology to change Verilog to SystemC. Abstract concepts of Verilog are proposed fittingly each one by one in SystemC.

This is a study on the difference between herbal formulations cited in Dongeuibogam and their original Chinese texts. We focused on the changes of herbal formulations from their original Chinese texts in the course of compilation of Dongeuibogam. We searched for the reason of this change on various aspects. Our findings confirmed the need for further studies in this field Through this study, we concluded that the changes between the original Chinese texts and Dongeuibogam are a consequent phenomena of historical progression. We hope lor this study to act as a foundation for further advanced studies.

Grid system is based on the Grid Security Infrastructure (GSI). GSI uses user's proxy to guarantee availability among multi-trust domains. Since grid system has been developed focusing on availability, GSI provides authentication and authorization performed by systems, but there are lacks of privacy consideration. For this reason, some researchers decide to use their own cluster system and do not want to use public grid systems. In this paper, we introduce a new privacy enhanced security mechanism for grid systems. With this mechanism, user can participate in resource allocation and authorization to user's contents more actively. This mechanism does not need to change previous middleware and minimize the computational overheads.

It is known that fine straightness of micro-wire can be obtained by removing residual stress induced during the manufacturing processes. Generally, residual stress is removed or minimized through several drawing processes with heat treatment. In this study, the residual stress at each straightening process is calculated and monitored by finite element analyses and the main reason of stress change is investigated.

A simple fault correction method for rotor position detection of a brushless DC(BLDC) motor with trapezoidal back EMF(electromotive force) using a Hall effect latch unit is presented. The reason why the Hall effect latch unit does not operate properly during the startup of a BLDC motor is thoroughly explained. To solve this problem, a simple code change method and its hardware implementation issues are proposed and discussed.

Latticed domes take form a curved surface by arranged members with certain patterns. For this reason, it is possible for the characteristics of vibration to complicate by change of various parameters of dome; grid-pattern, boundary condition and ratio of radius-height etc. Therefore, it is important to clarify the effect by these parameters before generalized dynamic response analysis. So this study deals with free vibration analysis of latticed domes and makes clear an effect of shape coefficient, that is, geometrical characteristics of latticed domes, on the vibration characteristics.

Income inequality in Korea has increased after the economic crisis, and the main reason for the widening of income distribution is due to the increase of the unemployed when analyzed using the Urban Household Report(UHR). However, income inequality has not decreased although the rate of unemployment decreased after 2000. Further data bases for income-related statistics are necessary to examine the exact causes of changing income inequality as a whole since the UHR covers only statistics on urban employees' wage and salary in Korea.

High-speed railway bridges subject to effect of statical loads by temperature change as well as dynamic loads by interaction between vehicle load which run specially fast and behavior of bridges, If suitable longitudinal expansion by temperature change of bridge does not happened, it can cause unhealthy condition for the parts of bridges as well as can generate addition stress to bridges, For these reason, Analysis and Estimation of data about behavior of bridges occupies important factor in that estimate the remaining life of bridges and select the maintenance, repair and retrofit. In this paper, Analysis for the long-term behavior of bridges using Longitudinal displacement and Temperature data that is actuality measured data to the bridges of Seoul-Busan high speed railroad test section has been made.

A railway open deck plate girder bridge without ballast should support relatively heavier vehicle loads compared with its self-weight. For such a reason, actual dynamic response of the bridge is considerably differing with normal prediction because additional masses added from vehicle to a bridge have an effect on the dynamic characteristics of the bridge. These differences affect to the estimation of a natural frequency change that adopted for one of the evaluation technique of strength decrease, and these make trouble to the analysis of a natural frequency from the field test data that measured at the bridge subjected to a running vehicle. In this study, classification of mass participation ratio for each component of open deck plate girder bridge without ballast and the comparison according to the change of vibration characteristics for the case of subjected to a running vehicle were accomplished.
