The purpose of this study was to classify the contents of self-image of college men and to investigate how clothing behavior was influenced by self-image, age, major, and the expenses of clothing. Samples were 342 male students of univer-sity in Seoul. Results of this study were following : 1. Four factors of self-image derived by factor analysis : F. 1‘mature-unmatured’;F. 2‘characteristic-ordinary’; F. 3‘conservative-open’; F. 4‘dominant-submissive’.2. 5 variables of clothing behavior were influenced by real self-image. Fashion was influenced by characteristic, open, dominant image, and the expenses of clothing. The ex-planatory power of the 4 variables was 29.3%. Aesthetics was influenced by characteristic, submissive, conservative image, the expenses of clothing, and age(R2=28.7%). Modesty was influenced by conservative and ordinary im-age(R2=6.5%). Coformity was influenced by ordinary image and the expenses of clothing (R2=5.7%). Comfort was influenced by dominant image and age(R2=5.3%). 3. 5 variables of clothing behavior were influenced by ideal self-image. Fashion was influenced by unmatured, characteristic, sub-missive image, and the expenses of clothing (R2=28.9%). Aesthetics was influenced by characteristic image, the expenses of clothing, and age(R2=23.5%). Modesty was influenced by conservative, mature, and ordinary image (R2=8.3%). Coformity was influenced by ordinary image(R2=1.9%). Comfort was influenced by mature image and age(R2=5.6%). The findings indicated that self-image had a significant effect on fashion and aesthetics, and characteristic image and conservative image were important variables that affected clothing behavior of college men.

The purpose of this study was to investigate the effects of children's individual characteristic on peer acceptance. The subjects were 234 6th grade elementary school children in Kwangju, Korea. The Questionnaires were used to collect the data on peer acceptance and social behavioral trait, physical attractiveness, demographic variables and the school achievement grade assessed by their teachers. The results were as follows : 1. Peer acceptance score, school achievement grade, prosocial behavior score, appearance score and physical attractiveness tend to be above the median scores. Aggression behavior score and withdrawal score tend to below the median scores. 2. The effect of individual characteristic variables on the peer acceptance found all significantly. 3. The influence of prosocial behavior, physical attractiveness, withdrawal behavior, aggressive behavior and school achievement grade on peer acceptance were found significantly. Prosocial behavior was the most influential variable on peer acceptance.

The growth behavior of the transverse crack, which was one of the most dangerous damages of rail defects, was investigated under mode I and mixed mode loading in rail steel. In the case of variable amplitude loading, the fatigue crack growth behavior was discussed using characteristic stress intensity factor ranges ${\Delta}_{rms}$. In addition, characteristic comparative stress intensity factor ranges ${\Delta}_{V,rms}$ was proposed to evaluate the quantitative effects of the variable amplitude under mixed mode loading. As a result, crack growth rate under variable amplitude loading was faster than that under constant amplitude loading.

The earthquake resistant design concept allows the nonlinear behavior of structures under the design earthquake. Therefore the response spectrum method provided in most codes introduces the response modification factors to consider the nonlinear behavior in the design process. For bridges, the response modification factors are given according to the ductility as well as the redundancy of piers. In this study, among influence factors on the nonlinear seismic behavior, the randomness of artificial accelerograms simulated with different durations, the pier ductility represented by the inelastic behavior characteristic curve and the regularity represented by pier heights are selected. The influence of such factor on the seismic behavior is investigated by comparing response modification factors calculated with the nonlinear time step analysis.

Despite the growing use of SNS and the increasing number of recruitment related to SNS, little research has been conducted between career preparation activities and relationship with SNS. Therefore, this study investigates the relationships among purpose of using instagram, flow of instagram and career preparation behavior using structural equation model, and by investigating the adjustment effect of the personal characteristic among them. To this end an online survey was conducted for students who want to be cabin crew. The results of this study show that motivation of using instagram had a positive and significant effect on flow of instagram, which in turn positively influenced career preparation behavior. Furthermore, it could be confirmed that there was a adjustment moderating effect on personal characteristic between purpose of using instagram and flow of using instagram. The results of this study suggest that the likelihood of recruitment for being cabin crew can be achieved by identifying mutual relationships among motivation of using instagram, flow of instagram, career preparation behavior, and personal characteristics.

The thermal analysis method containing micro drilling characteristic is proposed for the first time. There are such problems in thermal analysis of micro hole drilling as the thermal modeling complexity of drilling process and the undesirable micro drilling characteristic. Especially, the undesirable micro drilling characteristic prevents our using conventional thermal modeling. To model the thermal behavior of the micro drilling process, the finite different method, where heat source vectors are distributed by the measured rhrust and torque, is proposed. This method agrees with thermal behavior of the real system. And, it enable to predict the temperature field near the drill during. The validity of this method is verified in comparing with experimental results.

The purpose of this paper is that investigates the dynamic behavior characteristic of W.T.S(Wind Turbine System) and carries out the evaluation analysis during operating W.T.S. To investigate the dynamic behavior characteristic of W.T.S. the experiments to measure vibration of the blade from the attached accelerometer on the flap and edge section of the blade that is one of the most important elements of dynamic characteristic of W.T.S are performed. Natural frequency and mode shape are calculated with commercial program (STAR MODAL) using the measured vibration acceleration that receives the signal with F.F.T Analyzer from the accelerometer. For validation of these experiments. the finite element analysis is performed with commercial F.E.M Program (ANSYS) on the basis of the natural frequency and mode shape. The results indicate that experimental values have good agreements with the finite element analysis.

Methods commonly used to evaluate the improvement of lime-treated expansive soil include swelling characteristics and unconfined compressive strength. In the field, lime-treated expansive soils are in compacted unsaturated state. Soil water characteristic curves (SWCCs) represent a key parameter to interpret and describe the behavior of unsaturated expansive soil. This paper investigates the use of SWCC as a technique to evaluate improvements acquired by expansive soil after lime treatment. Three different lime contents were considered 2%, 4% and 6% by dry weight of clay. Series of tests were performed to determine the SWCC for the different lime content under curing periods of 7 and 28 day. Correlations between key features of the soil water characteristic curves of lime treated expansive soils and basic engineering behavior such as swelling characteristics and unconfined compression strength were established. Test results revealed that initial slope ($S_1$), saturated water content ($w_{sat}$), and air entry value (AEV) play an important role in reflecting improvement in engineering behavior achieved by lime treatment.

본 논문은 설계단계에서 지반조사와 수치해석을 통해 예측된 터널의 거동특성과 실제 시공단계에서 어떠한 변형특성을 보이고 있는지 RMR 및 계측데이터의 비교분석을 통해 선정된 터널지보시스템의 선택적 적용을 보여준다. 이는 파쇄대가 과대분포한 암반지역에 터널을 설치할 경우, 터널굴착지반의 거동은 지반의 특성과 보강공법 등의 영향에 따라 상이한 거동특성 때문이다. 그러므로, 본 연구에서는 지반설계자가 단층대 및 파쇄대가 과대 분포한 암반지역의 터널 설계시, RMR-계측 데이터 분석과 지반물성치 저감에 따른 매개변수 분석을 비교하여, 지반 설계자가 향후 유사한 파쇄대가 과대분포한 지역의 터널거동특성을 예측할 수 있도록 하고자 한다.
