The purpose of this study is to identify the antecedents of fashion consciousness. As antecedents, psychological variables and consumption-related variables were considered. Materialism and change seeking were included as psychological variables, and face conscious consumption, status consumption, and shopping enjoyment were included as consumption-related variables. It was hypothesized that materialism and change seeking not only influence fashion consciousness directly but also indirectly through face conscious consumption, status consumption, and shopping enjoyment. Data were gathered by surveying university students in Seoul, using convenience sampling. Three hundred five questionnaires were used in the statistical analysis. SPSS was used for exploratory factor analysis, and AMOS was used for confirmatory factor analysis and path analysis. The results showed that all the fit statistics for the variable measures were quite acceptable. In addition, the overall fits of the model suggest that the model fits the data well. The hypothesized relationship test proved that materialism directly influence fashion consciousness and that materialism and change seeking influence fashion consciousness indirectly through face conscious consumption and shopping enjoyment. Regarding their relative importance on fashion consciousness, shopping enjoyment was the most influential factor followed by materialism and face conscious consumption, in that order. In developing and implementing marketing strategies for fashion conscious consumers, marketers should focus on satisfying shopping enjoyment, materialism and face conscious consumption.

The RC beams subjected to bending and shear are an important substructure. After flexural cracking, the internal stress state in the beam could not be explained by the classical beam theory. In this study the internal force state factor is introduced to explain the stress state change in the RC beams. The internal force state factor of uniform load was expanded by superposition method using infernal force state factor of point load. As the load types change, the operator that would be calculated the internal force state factor was proposed.

In this paper, I analyze the GHG (greenhouse gas) emission factor of the domestic railway transportation sector using the LMDI (Log Mean Divisia Index) methodology. These GHG factors are the emission factor effect, energy intensity effect, transportation intensity effect, and economic activity effect. The analysis period was from 2011 to 2016, and the analysis objects were an intercity railway, wide area railway, and urban railway. The results show that the GHG emission of railway transportation sector decreased during these 6 years. The factors decreasing the GHG emission are the emission factor effect, energy intensity effect, and transportation intensity effect, while the factor increasing the GHG emission is the economic activity effect.

The effects of design parameters for small scale hydro power(SSHP) plants due to climate change have been studied. The model to predict hydrologic performance for SSHP plants is used in this study. The results from analysis far rainfall conditions based on KIER model show that the capacity and load factor of SSHP site had large difference between the period. Especially, the hydrologic performance of SSHP site due to rainfall condition of recent period varied in design flowrate sensitively. However climate change gave small effect in load factor of existing SSHP plant. And also, the methodology represented in this study can be used to decide the primary design specifications of SSHP sites.

Influence of the metallization during the manufacturing of the ceramic multilayer capacitor on the dielectric properties was studied as a change of the capacity and the dissipation factor. Due to the change of the relative dielectric constant as a function of the measuring temperature the influence of the metallization could be obtained and the change of the dissipation factor as a function of the measuring frequency was anaysed. In order to investigate the boundary effect between the metallization and the dielectric a kind of microstructure model at the internal Grain and Grain Boundary was constructed and tried to analyse the change of the dielectric properties.

This paper proposes central monitoring system(PVCMS) based on a TCP/IP network for effective integrating management about photovoltaic systems. We don't gain confidence the result of production simulation, because the output of PV system have many various environmental change factor. So if we can obtain real operated data about each sites and system types to use PVCMS, we can define the environment change factor to compare with simulation data. And this paper try to access about total management and data analysis methods of renewable energy through results analysis to synthesize of the operation.

DSC-HDTV 시스템은 영상에 존재하는 공간, 시간, 진폭의 중복성을 제거하기위하여 변환 부호화, 움직임 보상 예측 부호화, 적응 양자화를 이용한다. 본 논문에서는 장면 변화와 전송 잡음으로부터 신속히 화질을 복원하는데 이용하는 누설요소의 적용 방법과 인간 시각 시스템을 이용한 인식하중치를 구하여 적응 양자화하는 방법을 제안한다. 인식하중치는 대비 민감도, 시공간 매스킹과 주파수 민감도에 따라 구한다. 적응 양자화는 인식하중치와 버퍼이력상태로부터 얻은 전체 왜곡 레벨을 이용하고 그에 따른 잉여 비트량은 다음 프레임의 화질 개선에 이용된다. 장면이 변할 경우 복원된 영상은 큰 양자화 오차를 포함하기 때문에 움직 보상 예측 부호화에서 구한 변위프레임 차신호가 큰 값이 되어 비트량이 증가하고 버퍼의 상태가 불안정하게 된다. 그러므로 본 논문에서는 누설요소를 장면이 변할 경우 0으로 하고 그이후의 프레임에서의 15/16으로 고정하여 전체왜곡레벨을 표준편차를 이용하여 조절한다. 실험결과 제안된 방법의 영상의 화질은 수 프레임내에 복원되고 버퍼상태도 신속히 안정화된다.

We measured the time-dependent concentration of VOCs emitted from Ondol floor, furniture, and the wall made of various building materials. After obtaining results from the previous measurement, we developed the estimation equations of the concentration decay, and obtained the estimated graphs for the concentration decay under different air change rates and loading factor conditions by using the estimated equations. We conducted our tests by applying our measurements to real residences for 110 days in the case of furniture and for 40 days in the case of the floor. We also conducted experiments in the cases of various wall materials for 7 days which totaled 10 times. We used the GC/FID for experiments for real residences accord-ing to the specified procedures of the NIOSH 1501, and carried out experiments for wall materials according to the specified procedures of the ASTM 5116-97. When conducting experiments for wall materials, we set the temperature and relative humidity at $23^{\circ}C$ and $50\%$, respectively. We also set the air change rate and loading factor at 0.7/h and $1.617 m^2/m^3$, respectively. Our results showed that it is possible to predict proplrly the time-dependent concentration decay of VOCs by using logarithmic functions in both cases of experiments for real residences and for wall materials. Furthermore, we found that the concentration decay rate of VOCs increased rapidly as the air exchange rate increased while the concentration decay rate decreased as the loading factor increased.

The purpose of this study is to investigate empirical evidences of productivity of life insurance institutions in Malaysia. Therefore, this study attempts to explore the productivity of the life insurance institutions in Malaysia. The overall findings show that the total factor productivity (TFP) has progressed by 2.5% per year during the study period from 2012 to 2016 in the Malaysian insurance industry. However, TFP change has declined from 2012 to 2015 and observed a negative growth in 2015-16 (3.3%). The highest productivity progress was documented during 2012-13 at a rate of 11.7% while the minimum productivity progress was during 2014-15 (only 0.2%). The results also indicate that the decomposition of TFP found that overall progress could mainly be attributed to technological change (TC). However, technical efficiency change (TEC) and pure technical efficiency change (PTE) have negative impact on TFP. The findings also show that most of the insurance companies have a steady growth. Therefore, this study will contribute new insights for the policy makers and insurance institutions to take appropriate steps in developing relevant policies for increasing productivity of insurance institutions in Malaysia.
