Social interactions often involve encountering inconsistent information about social others. We conducted a functional magnetic resonance imaging (fMRI) study to comprehensively investigate voxel-wise temporal dynamics showing how impressions are anchored and/or adjusted in response to inconsistent social information. The participants performed a social impression task inside an fMRI scanner in which they were shown a male face, together with a series of four adjectives that described the depicted person's personality traits, successively presented beneath the image of the face. Participants were asked to rate their impressions of the person at the end of each trial on a scale of 1 to 8 (where 1 is most negative and 8 is most positive). We established two hypothetical models that represented two temporal patterns of voxel activity: Model 1 featured decreasing patterns of activity towards the end of each trial, anchoring impressions to initially presented information, and Model 2 showed increasing patterns of activity toward the end of each trial, where impressions were being adjusted using new and inconsistent information. Our data-driven model fitting analyses showed that the temporal activity patterns of voxels within the ventral anterior cingulate cortex, medial orbitofrontal cortex, posterior cingulate cortex, amygdala, and fusiform gyrus fit Model 1 (i.e., they were more involved in anchoring first impressions) better than they did Model 2 (i.e., showing impression adjustment). Conversely, voxel-wise neural activity within dorsal ACC and lateral OFC fit Model 2 better than it did Model 1, as it was more likely to be involved in processing new, inconsistent information and adjusting impressions in response. Our novel approach to model fitting analysis replicated previous impression-related neuroscientific findings, furthering the understanding of neural and temporal dynamics of impression processing, particularly with reference to functionally segmenting each region of interest based on relative involvement in impression anchoring as opposed to adjustment.

이미지 생성 모델은 다양한 분야에 적용되어 데이터 부족 문제와 시간 및 비용 문제를 극복하고 있다. 그러나 규칙적 패턴 이미지에서의 이미지 생성과 해당 데이터의 결함 검출에는 한계를 가진다. 본 논문에서는 이미지 생성 모델의 패턴 이미지 생성의 가능성을 확인하고 OLED 패널의 결함 검출을 위한 데이터 증강에 적용하였다. OLED 결함 검출 모델을 학습하기 위해 필요한 데이터는 OLED 패널의 높은 비용 문제로 실제 데이터 세트를 확보하기 어렵다. 그렇기 때문에 해당 데이터 세트를 확보한다 하더라도 여러가지 결함 유형을 정의하고 분류하는 작업이 필요하다. 이를 위한 가상의 기반 데이터 세트를 획득할 OLED 패널 결함 데이터 획득 시스템을 소개하고, 이미지 생성 모델로 해당 데이터를 증강한다. 또, 확산모델에서의 패턴 이미지 생성의 어려움을 확인하여 가능성을 제안하고, 이미지 생성 모델 이용한 데이터 증강 및 결함 검출 데이터 증강의 제한 사항을 개선하였다.

Recently, consumers are tend to purchase the user-centered designed product using interface enginnering and human factors techniques. Therefore, it is important that the designer's requirements should be analyzed focused on the human machine interface. This paper described the interface usability evaluation technique(suvjective evaluation) for the interface between user and product. This methodology is the integrated interface usbility evaluation method AHP and Conjoint Analysis. AHP(Analytic Hierarchy Process) is a multicriteria decision model to give priority after expressing hierarchically for decision making problem. Conjoint Analysis enduavors to unravel the value, or partworths, that consumers place on the product or service's attributes from experimental subjects' evluation of profiles based on hypothetical products or services. A new usability test methodology proposed by this paper includes techniques jointed both consistency test by AHP and experimental subjective evaluation of profiles by Conjoint Analysis for evaluating the user's emotion and impression.

This study used the hypothetical path model to investigate individual traits(attachment, reciprocal relationship, and self-esteem), situational evaluation(justification, and intention) and jealousy level in adolescents. Subjects were 853 7th, 9th, 11th grade students in the city of Daegu. Results showed that scores of girls were higher than boys on self-reported and peer-reported jealousy level, attachment, reciprocal relationship, adaptive expression and non-adaptive expression. Scores of boys were higher than girls for self-esteem, justification. Self-reported jealousy level was affected by situation evaluation(justification and intention) and attachment. Peer-reported jealousy level was affected by reciprocal relationship. Jealousy expression modes were affected by self-reported jealousy level and attachment.

The purpose of this study was to suggest the elderly consumer's consumer informationization education connected with the informationization education for the community by Chung-buk province. Three hundred seventy nine elders were surveyed, with questionnaires from August 12 to September 30, 2002, and a hypothetical model of the consumer informationization education on the basis of the informationization education for the suggestion of the elderly consumer's consumer informationization education was tested. The results were as follows: the perception and the attitude on the informationization education of the elderly were, with a statistical significance, positively related to the perception and the attitude on the consumer informationization education of the elderly. The consumer informationization education (basis, application, attendance, and mission) on the basis of the informationization education (basis and application) in steps was supported as a suggestion for the elderly consumer's consumer informationization education.

In order to study the fatigue crack and retardation mechanism in variable loading, the effects of crack tip branching in crack growth retardation were examined. The characteristics of crack tip branching behavior were considered with respect to microstructure and crack tip branching angle was examined. Crack tip branching was observed along the grain boundary of finite and pearlite structure. It was found that the branching angle ranges from 25 to 53 degrees. Using the finite element method, the variable of crack driving farce to branching angle was examined. The effective crack driving farce (K$\_$eff/) decreased as the branching angle increased. The rate of decrease was 33% for kinked type and 29% for forked one. It was confirmed that the effect of crack tip branching is a very important factor in crack growth retardation. Therefore, crack branching effect should be considered in building the hypothetical model to predict crack growth retardation.

This study used Structural Equation Modeling(SEM) to test causal relationships among perceived social supports, self-control, and subjective well-being in a sample of 325 5th and 6th grade elementary school children. Correlations of observed variables showed statistically significant among perceived social support, self-control, and subjective well-being. The goodness-of-fit of the hypothetical structural model in the study, perceived social support having direct effects on self-control and subjective well-being, and self-control, retaining the influence of perceived social support, having effects on subjective well-being-showed fairly acceptable levels. The results revealed that perceived social supports increase children's subjective well-being, and these supports also increase children's self-control, which indirectly influences children's subjective well-being.

This paper is an attempt to give an account of presupposition inheritance (henceforth PI) in conditionals from a functional-discourse perspective. The focus of study is on how to evaluate the embedded presupposition (EP) nested in the hypothetical world. I propose the view that if the EP satisfies the condition on the presupposition satisfaction, it becomes background information in the relevant world, arguing against the theories which employ simple cancellation or disappearance of those EPs. The discourse processing among discourse participants is to be considered in the light of functional significance for the explication of the contrastive mechanism of presupposition and assertion. I advance a revised model of PI in conditionals and analyze several problematic cases of conditionals, with a particular attention to their DRSs.

A molecular-thermodynamic model to describe the salt-induced protein precipitation is developed based on the perturbation theory. We employed the modified perturbed hard-sphere-chain (PHSC) equation of state for copolymer mixtures to take into account the pre-aggregation effect among protein particles. Hypothetical pressure-composition diagrams are computed with various size differences and salt concentrations. The precipitation behaviors are also studied for various types of pre-aggregation effect for the given systems.
