Recently, the properties of early-age concrete are increasingly important because these properties directly influence the behavior of early-age concrete structures including stress and cracking behavior. Nevertheless, the studies on early-age concrete are limited to strength and temperature development. The purpose of present study is to propose a simple and rational method which can predict the stress and strain behavior of young age concrete. A series of test have been done to measure the temperature development, strains and stresses in concrete members. The concept of equivalent age was used to define the degree of hydration and this degree of hydration was used to calculate the strength and elastic modulus. The critical degree of hydration and thermal expansion coefficient were calculated using experimental data. It is seen that the critical degree of hydration range from 0.05 to 0.11 based on the measuring method. The thermal expansion coefficient was calculated based on the measured non-mechanical strain and it is found that the coefficient decreases slightly with the increase of age. The consideration of critical degree of hydration in calculating stresses gives more accurate results. The present study provides useful method and data in evaluating early-age behavior of concrete structure.

Purpose - Numerous studies have tried to assess the role of a warranty as an explanatory instrument for product quality. While one study argued that manufacturers signal their superior quality to consumers by extending the duration of a warranty, quality is not necessarily related to warranty and a warranty for a short duration is a sign of high product quality. However, there are limitations to measuring product quality in terms of a single variable such as a warranty. Some other studies have evaluated the influence of brand power or value and price on the supposed quality of a product while the influence of warranty was found to be insignificant. Research design, data, methodology - The study analyzes the influence of brand power and the country of origin effect on consumers' perception of product quality in line with warranty and establishes a priority strategy. Especially, consumer experience has a significant influence on state of the art technology products like applied home electronics as these goods are generally quite expensive and consumers expend significant energy in purchasing them, so the associated warranty and brand can have a critical role in the decision making process. The price of the product was excluded in this discussion as it continually varies with the market share of the product. Results - The results of the analysis are as follows: First, each of the factors such as the standard of the warranty, brand power, and country of origin effect influences the degree of satisfaction of an individual. Second, the factors brand power and quality of the warranty interact both complementarily and synergistically at a time, depending on the brand power. As brand power is more significant, the degree of satisfaction is greater in case of products with low quality warranty compared to those with high quality warranty. Third, the brand power and country of origin effect present a complementary interaction. Fourth, the country of origin effect and quality of a warranty interact synergistically. Conclusions - Thus, the higher the quality of warranty, greater is the increment in the degree of satisfaction. The comprehensive study on the effect of the country of origin on the purchase decision process and the degree of satisfaction compared to the other elements shows that in case of Japanese and Korean markets the brand power of a company is desirable in sustaining the quality of warranty to the industrial average. Also, there is no significant improvement in the perceived quality of the product when the quality of the warranty is lowered. Therefore, the warranty effect diminishes when the value of the brand is known, while it perishes when both the brand power and the country of origin effect are strong enough.

This study examines the relationship between perceived risk and regret, the influence of regret, and the regret-solution effort upon post-purchase behavior. These causal pathways are controlled by moderated different impulse buying types. The results of the study are three-fold. First, consumers with high social and convenience risks resulted in the high levels of regret. Second, the higher the regret then the higher the negative purchase intention and the lower the positive purchase intention. Consumers who emphasize the regret-solution have high positive purchase intentions and the low negative purchase intentions. Lastly, as for the influence of the regret upon the negative purchase intention, the 'recollection impulse buying type' has the greatest influence among all other types. No impulse buying types have a positive influence on purchase intention. As for the influence of the regret-solution efforts on the positive purchase intention, the 'pure impulse buying type' had the greatest influence. Only the 'suggestion impulse buying type' influenced the negative purchase behavior intention. The post-purchase intention depends on the level and the degree of the regret-solution efforts of the consumer. This study contributes to the examination of the different impulse buying types that influence the moderators in the causal pathway of the risk perception to the post-purchase buying behavior.

A user influence discrimination scheme using big data from social networks is needed. In this thesis, we propose a user influence discrimination scheme considering reliability in social networks. The proposed scheme measures reliability scores through social activities and simplifies a social network by collecting only reliable users. It also derives user influence by considering direct and indirect influences that depends on network degree between users. As a result, the proposed scheme improves the expandability of the user influence. In order to show the superiority of the proposed scheme, we compare it with the existing scheme through performance evaluations in terms of reliability and user influence.

This study was attempted to identify the knowledge to breast-feeding and the performance of nursing activities for breast-feeding and to test 'how does the degree of knowledge to breast-feeding influence the nursing activities for breast-feeding?' The subjects were 180 nurses working in delivery rooms, nursery, obstetrics & pediatrics wards or OPD of obstetrics & gynecology of 8 general hospitals in Pusan as of August 3 through 13, 1996. The results are abstracted as follows. 1) Subject nurses' age, 25-29 was 45.6%(the major), education levels graduates from junior college were 95.0%, unmarried status was 62.2%, 76.5% of married nurses had children, 39.7% in-service education for Breast-Feeding, 33.7% did nursing activities for breast-feeding actively, the reason for inadequate activities for breast-feeding was 'too much other tasks.' 2) The degree of knowledge to breast-feeding ; mean score was 13.54, the degree of performance of nursing activities for breast-feeding : 92.38±20.93 points out of possible 145 points (3.19±.74 out of possible 5 points) moaned that it was a low level. 3) The hypothesis 'the nurses who have higher degrees of knowledge to breast-feeding will show higher degrees of performance of nursing activities for breast-feeding than the nurses who have lower degrees of knowledge to breast-feeding' was tested by t-test(t=-.01, P=.9888), but rejected because it turned out statistically not significant at the level of P<.05. Above results suggested the degrees of knowledge to breast-feeding and the degrees of performance of nursing activities for breast-feeding were generally low and the degree of knowledge didn't influence the nursing activities. Researchers believe that the education for breast-feeding by the nurses need to be performed systemically & practically and new method of breast-feeding education program need to include hospital managers as well as nurses related mothers and their family. In audition, researchers propose the introduction of &lactation specialist system&, for the specialist can change the attitude of feeding-mothers positively with their specialty and authority.

The purpose of this study is to investigate recognition degree and acceptability of fashion trends of new consumers who live in digital era, and to determine how these factors have influence on their use of fashion trend information. The study was conducted with 696 people from 15 to 34 years old. A self-administrated questionnaire based on the results of previous researches was developed. The data were analyzed with statistical analyses such as frequency analysis, mean, factor analysis, t-test, ANOVA, correlation and regression analysis. The results are as follows: first, new digital consumer's recognition degree (RD) of fashion trends is 7.85 on the average, given that the top of scale is 20.0, it is quite low. Of fashion trend RD, fashion item RD is the highest. The female subjects recognize fashion trends better than the male subjects. Second, fashion trend acceptance of new digital generation is classified into 5 factors: 'search acceptance', 'lead acceptance', 'follow acceptance', 'non-acceptance', and 'delay acceptance'. The female subjects show higher degree in the factors of 'search acceptance', 'lead acceptance' and 'follow acceptance' of fashion trend than the males; hence it means that the females have more positive attitudes in fashion trend acceptance than the males. Third, there are significant differences between genders in the fashion information utilization. Compared to the males, the females more use fashion information on style, fabrics and color. Concludingly, their fashion trend recognition degree and acceptance made an influence in part on their utilization of fashion information.
