This paper presents a study on the effects of localized steel-concrete bond degradation on the flexural behaviour of RC beams. A finite element analysis is undertaken to complete the experimental analysis. The first part deals with an experimental study on beams where bond was removed by using plastic tube at different locations and for various lengths. The flexural behaviour was studied at global scale (load-deflection) and local scale (moment-curvature). The second part, a numerical study using a simplified special finite element (rust element) modelling the rust layer occurring between reinforcement and concrete with corrosion was conducted in order to find the relation between the degree of corrosion and the degradation of the steel-concrete bond. The computed value of the corrosion degree corresponding to the total degradation of bond has been used in a second time to model the tests, in order to evaluate the influence of the loss of bond, the steel cross section reduction, and the combination of both. The results enable to evaluate the influence of the different corrosion effects on the flexural behaviour, according to the length and the location of the corroded zone.

The purposes of this study were to reveal the relation of consumer value variables and to identify the difference of clothing information exploration behaviors on consumer value variables. The data were collected from 267 college women residing in Gwangju using a Questionnaire to general value, clothing value, consumption value and clothing information exploration behaviors. It were analyzed with factor analysis, cluster analysis, T-test, ANOVA and multiple regression analysis using statistical program SPSS 10.0. The results of this research were as follows: 1. Only one factor of general value had a significant influence on 'practical' of clothing value. All of general value and clothing value had a significant influence on the whole consumption value. 2. Clothing information search behaviors was divided into three factors: 'variety pursuit' 'active information collection' and 'uniqueness pursuit'. General value group had a significant difference in 'variety pursuit' and 'active information collection' behavior. Clothing value and consumption value group had a significant difference in all factors of clothing information search behaviors. By implication, this study could be explain each contributions of consumer values and suggest useful variable of consumer values in future clothing behaviors research.

Purpose - This paper aims to identify factors that influence the users' word-of-mouth intention (WOMI) regarding mobile apps, focussing on the impacts of technology acceptance model (TAM) and social network theory. Research design, data and methodology - Based on TAM, this study integrates social network theory into the research model. The 317 sets of data collected in a survey were tested against the model using SmartPLS. Results - Our findings suggest the following: 1) Personal innovativeness positively influences perceived usefulness (PU), perceived ease of use (PEU) and perceived enjoyment (PE); 2) PEU affects PU and PE; 3) Both PU and Satisfaction are directly correlated with WOMI. Although PEU and PE has no direct impact on WOMI, they may indirectly affect WOMI via Satisfaction, as PU, PEU and PE all positively influence satisfaction; 4) Network density and network centrality both play a mediating role in the relation between PEU and WOMI. Referral Reward Program have a positive moderating effect on the relation between PU and WOMI. Conclusions - The findings of this study illustrate the traits of Apps that can promote users' WOMI, as well as the characteristics of people who are more likely to participate in the word-of-mouth process. The findings provide a theoretical basis for app developers to make word-of-mouth a marketing strategy.

임팩트이온화는 고전계하에서 고에너지를 지닌 캐리어간 산란으로써 전자전송해석에 필수적인 요소이다. 그러나 포물선 또는 비포물선 E-k관계는 고에너지에서 실제 밴드구조와 매우 상이한 결과를 나타내므로 임팩트이온화에 대한 정화한 모델은 풀밴드 E-k관계와 페르미의 황금법칙을 이용하여 제시하고 있다. 본 연구에서는 풀밴드를 이용하여 실리콘 임팩트이온화율에 영향을 미치는 상태밀도와 에너지밴드구조 관계, overlap integral의 에너지에 대한 변화를 조사 분석하였다. 실리콘의 에너지밴드구조를 구하기 위하여 경험적 의사포텐셜방법을 사용하였으며 상태밀도를 구하기 위하여 사면체방법을 사용하였다. 또한 임팩트이온화율을 구하기 위하여 페르미의 황금법칙들 사용하였다. 결과적으로 상태밀도는 에너지증가에 따라 단조 증가하는 임팩트이온화율과 달리 에너지밴드구조에 따라 변화하였다. 그러나 overlap integral은 에너지증가에 따라 큰 값을 갖는 분포가 증가함으로써 임팩트이온화율에 직접 영향을 미치는 것을 알 수 있었다.
