This study investigates the influence of self-efficacy in purchasing clothes in the consumer satisfaction formation process. A survey was conducted on 300 adults living in the Seoul and Gyeonggi area and 231 completed questionnaires were used for analysis. The survey questionnaires measured the respondent's self-efficacy in purchasing clothes, expectation, perceived performance, expectation confirmation, and satisfaction level. The data were analyzed by moderated regression analysis. The results are as follows. First, for apparel products, perceived performance, and expectation confirmation have a direct effect on consumer satisfaction, while expectation has no direct effect on consumer satisfaction. This finding agrees with the results reported in a previous study on consumer goods with low ambiguity in assessing products and services including sneakers, underwear, cereals, and financial services. Second, the lower the self-efficacy in purchasing clothes, then the increased effect of the expectation confirmation that influences consumer satisfaction. However, the self-efficacy in purchasing clothes did not show any moderating effect on the perceived performance affecting the consumer satisfaction. The self-efficacy in purchasing clothes seems to have a moderating effect on the consumer satisfaction formation process by affecting the ambiguity in pre-purchase product assessment and not in post-purchase product evaluation.

We uncover a nexus between actual inflation, inflation perceptions and expectations in Korea through analyzing micro as well as aggregate data from the Consumer Survey. We document two novel findings. First, households' subjective perceptions of inflation exert more impact on expectation formation than actual inflation. Second, inflation perceptions are broadly in line with the trajectory of the inflation trend. This is attributable to the fact that changes in actual inflation have been generated mainly by the consumption items whose price changes are perceived more sensitively as those items are frequently bought or have a larger share in household expenditures. Conducting a cross-country comparison, we find that information rigidity in expectation formation process and the nexus between perceptions and expectations of inflation prove to be stronger in Korea. Additionally, we reconfirm the existing finding that the scope of information utilized for forming inflation expectations is fairly circumscribed.

사진기에서 고품질의 영상을 획득하기 위해서는 적절히 노출 시간을 조절하게 되는데 이로 인해 각각 독립적으로 얻어진 영상들의 노출 시간은 서로 달라진다. 이는 여러 영상의 열을 정렬하는 과정 등에서 부정확한 결과를 초래할 수 있으므로 영상들의 노출 시간을 동일하게 맞추어 줄 필요가 있다. 그런데, 노출 시간을 알지 못하는 경우에는, 하나의 영상을 기준으로 다른 영상들의 상대적 노출 시간을 추정하고 보정하는 알고리즘에 대한 연구가 필요하다. 본 논문에서는, 사진기의 모델 함수를 고려할 필요 없는, 최소 오류 개념에서 최적의 예측기인 conditional expectation을 사용하여 노출 보정을 시도하였다. 나아가서, 불규칙한 노출 또는 히스토그램 특성을 위한 적응 노출 보정 기법을 제안하였다. 이때 blocking artifact 및 overfitting 등의 문제를 완화시키기 위한 인접의 화소를 사용하는 기법을 도입하였다. 디지털 사진기 및 투과전자현미경을 통하여 얻어진 실제 영상을 사용한 모의실험을 통하여 성공적인 노출 보정 수행을 확인할 수 있었다.

Galactic bars are supposed to be a channel of gas inflow to the galactic center and thus possibly help nuclear star-formation and AGN activities. However, previous studies based on small local samples did not agree with this expectation. We find it necessary to examine the expectation using a large sample and so investigate the effects of bar structures on galactic nuclear activities, based on the Sloan Digital Sky Survey (SDSS) DR7. We used 6,348 late-type galaxies brighter than Mr = -19.0 in the redshift range $0.01{\leq}z{\leq}0.05$. Late-type galaxies are visually classified into barred or unbarred galaxies using SDSS color composite images. We compare the fractions of galaxies showing star-formation and AGN activities among barred and unbarred galaxies as a function of optical color, stellar mass, and black-hole mass. We have found that bar enhances nuclear star-formation activity on galaxies having low stellar mass, and low black-hole mass. This effect is stronger in redder galaxies. In the case of AGN, bar effects are higher in intermediate-mass galaxies. Bars also have an effect on the strength(!) of the star-formation and AGN activity in our sample as well. Thus, it seems that nuclear activities are powered by gas inflow from galactic bar structures perhaps not always but under certain conditions.

Due to fierce competition, many domestic fashion businesses are suffering difficulty in securing and maintaining customers. Accordingly, fashion companies are devoting all their energy to secure customers by using high quality and diverse strategies for distribution and promotion, and to secure loyalty by satisfying customers with the offer of excellent service. Thus, it is very important to provide systematic service recovery strategy available for handling service failure effectively. Therefore, the purpose of this study is comprehensively analyzing influences of expectation dis-confirmation and perceived justice for service recovery upon consumers' satisfaction and loyalty. The findings are as follows. First, as for the service failure that customers experienced, the more consumers who expect it to be recovered led to the higher formation of expectation-compensation dis-confirmation. Second, it was indicated that the higher seriousness in service failure that customers experienced led to the lower satisfaction and loyalty to service recovery. Third, as a result of examining influence of expectation-compensation dis-confirmation for service-failure recovery upon consumer satisfaction and loyalty, the customers who showed more positive dis-confirmation to expectation-compensation were indicated to form the more satisfaction and loyalty. Fourth, as a result of examining the influence of the perceived justice in the process of service-failure recovery upon customer satisfaction, all in 3 dimensions of justice had effect on customer satisfaction.

This paper focuses on the policy framework about "Quantitative and Qualitative Easing (QQE)" of Japan, and analyzes reasons why the policy goal was not reached. The QQE was introduced by the Bank of Japan in 2013 with the purpose of meeting the price stability target of 2% and getting out of deflation that prevents sustained price decline. However, despite the implementation of the bold monetary easing policy unprecedented in the world, the policy goal was not achieved as of June 2018. As a result of analyzing the causes, the following three structural factors were confirmed. 1) The rise in prices by QQE was limited because Japan's consumer price is strongly depending on import price. 2) The effect is high degree of uncertainty and limited because theoretical framework of reflationist which adopted QQE depends on "expectation formation" by "self-fulfilling expectation" and "multiple equilibria". 3) It was confirmed that the expansion of the monetary base did not lead to money stock due to the existence of Japanese liquidity trap, long-term low interest rate policy.

This study measured college students' levels of satisfaction with their cyber learning through an online survey of students who had taken one or more cyber learning before. 500 returned and usable questionnaires were analyzed and SPSS WIN 12.0 was used for the descriptive statistics, t-test, factor analysis and analysis of covariance structures. The results are as follows; First, college students were very interested in their cyber learning. Their decision to take the cyber learning was initiated more by emotional motives (m=3.13) than by rational motives (m=3.35). Second, the consumers' expectations for the cyber learning were divided into the 'Expectation for service quality' and the 'Expectation for economy,' and their 'Expectation for economy'(m=4.02) was higher than their 'Expectations for service quality'(m=3.60). Third, the consumers' expectations for the cyber learning and the results of the cyber learning were analyzed, and a discrepancy between these two were also analyzed. The analysis of discrepancy between the two showed that the average of the results was lower than that of the expectations, which means that the cyber learning did not meet the consumers' expectations in every aspect, However, the average satisfaction level was 3.20, which means consumers were satisfied with the cyber learning overall. Fourth, causes of dissatisfaction with the cyber learning were divided into internal factors due to personal matters and external factors due to classes and other factors. It was found that dissatisfaction due to internal factors was greater than that due to external factors. Lastly, the factors affecting satisfaction/dissatisfaction with the cyber learning and willingness to use it again were analyzed. The results showed that the motive for its use affected the formation of expectation but it did not affect the results. Satisfaction with the cyber learning affected the willingness to use it again positively. However, the effect of dissatisfaction on the willingness to use it again was not statistically significant.

Village formation through landscape agreements of all things has sufficient expectation effects in that it outgrows the existing hardware- and development-oriented methods and realizes software- and policy-centered measures developed on the basis of environments and amenity. Village formation through landscape agreements is a work toward future in the long term. Villages are moving in the flow of time. Recognition on life environments and changes in consciousness of residents may be the most direct head start showing the possibility of village formation. However, the signs of such changes are yet uncertain and it is difficult to expect the changes in conscious ness would lead to realization and accomplishment. Therefore, it is needed to construct a society-wide system in which administration, experts, and local residents altogether support resident-led village formation, as well as efforts to enhance and expand the sprouts of hope.

The purpose of this study was to investigate the components in friendship as reported by Korean children of School age Specially, four major aspects of friendship - definition of friendship, friendship formation, friendship expectation, and friendship termination were explored. The subjects of this study consisted of 600 elementary school children in Grades 1 through 6, 50 males and 50 females at each grade level. Based on Bigelow (1977) five open - ended questions were administered. First and second graders were interviewed individually while 3rd-6th graders replied to a questionnaire in class. For content analysis, responses of each child were coded into 22 categories and each category was assigned a score from 1 to 4 according to its frequency. The data were analyzed by factor analysis. The results showed that four major aspects of friendship in Korean children of school age were found to consist of four different factors. DEFINITION OF FRIENDSHIP was found to consist of the factors; 1) reciprocity of liking vs. helping 2) global evaluation vs helping 3) sharing and 4) common activities. FRIENDSHIP FORMATION was found to consist of the factors; 1) situational effects vs complex evaluation 2) structural dimension vs common activities 3) helping and 4) staring. FRIENDSHIP EXPECTATION was found to consist of the factors; 1) mutuality 2) common activities vs. loyalty & commitment 3) exclusive - dyadic activities vs. admiration (character) and 4) interactive a1truism. FRIENDSHIP TERMINATION was found to consist of the factors; 1) physical separation vs disappointment (character) 2) conflict 3) physical separation vs. psychological dimension and 4) general altruism.

Due to the rapid growth of social networking community (SNC), research into SNC user's behavior has recently emerged as an important issue in information systems. An individual makes a decision whether or not to continually use his or her own SNC and to purchase digital items to decorate it. Most previous research has focused on a user's continuance intention and has ignored the importance of purchase intention. This study develops and empirically tests an integrated model designed to predict a user's two types of behavioral intention：continuance intention and purchase intention based on the expectation-confirmation model (ECM) and a dual model of relationship maintenance mechanism.The results indicate that perceived usefulness, satisfaction, personalization, and switching cost have important influences on the formation of SNC continuance intention. The results also show that perceived usefulness and satisfaction does not have any significant impacts on purchase intention, while personalization, learning, attractiveness of alternatives, and continuance intention significantly affect it.
