The purpose of this study was to identify the effect of education service quality (quality of professor service, quality of curriculum service) on career decision-making, self-efficacy, career decision level, and career preparation behavior. Appropriate measures were developed and tested on 426 respondents of Gyeongnam province in South Korea with a cross-sectional questionnaire survey. To ensure the reliability and validity of the questionnaire, frequency analysis, reliability analysis, and validity analysis were conducted. To ensure the reliability and validity of the measurement model, the CFA(confirmatory factor anlaysis) were conducted. The SEM(structural equation modeling) analysis was undertaken to perform the path analysis among the variables and to assess the suitability of the model. MCFA(multi group CFA) and MSEM(multi group SEM) were performed to confirm the moderation effect. Results of the study are summarized as follows: Firstly, education service quality has positive effects on career decision-making self-efficacy. Second, career decision-making self-efficacy has positive effects on career decision level and career reparation behavior. Third, career decision level has positive effects on career reparation behavior. Finally, it was found there exists a moderating effect of freshman/registered student between education service quality, career decision-making self-efficacy, career decision level, career preparation behavior. As a result of this study, it is suggested that investigation of extraneous variables which help to improve career preparation behavior and career decision level as for career of university student will contribute to university education.

In the acceptance of new technology products, not only the characteristics of the product itself, but also the consumer's psychological perception of the product has a great influence. This study analyzed the effects of psychological variables such as perceived risk, technology trust, and optimistic bias on consumers' intention to accept new technology products. This study selected nanotechnology, and we found consumers with high perceived risk showed relatively low intent to accept nanotechnology products compared to consumers with high perceived risk. However, in case of high level of technology trust, consumers with high perceived risk did not show any significant difference in the intention to accept nanotechnology products. We also found that such moderating effect of technology trust is mediated by optimistic bias. We hope that the findings of this study can give meaningful implications to nanotechnology developers, marketers, and policy makers in nanotechnology industry.

On 11 June 2021, the Supreme Court ruled that the judgment of the lower court was justified for the subject case, that the plaintiff could assert the defendant's liability for default due to incomplete performance even though the warranty period for defects which stipulated in the particular condition of the contract has expired. In Korean civil law, the concurrent between the exclusion period for defect warranty and the extinctive prescription for default liability is conceded, since the exclusion period and the extinctive prescription have their respective purposes in law, therefore these two should be judged by harmonizing them based on that they are mutually related. If the subject judgment is generalized, there is no reason to exist for the provisions of defect liability in the construction contract any longer. This study examines the subject judgments through the general theory and precedent case studies on the defect liability and default liability, then derived any problems that may arise if the subject judgment is generalized. In addition, based on a realistic model, it was suggested for a practical improvement method that both the provisions of the warranty period shall be changed realistic and to stipulate the character of its nature as written provisions in the contract.

This study evaluated the dietary habits and dietary quality of the Korean elderly according to muscle strength status. This study was conducted on the elderly aged over 65 years who participated in the 2014-2018 Korea National Health and Nutrition Examination Survey. Subjects were classified into the normal muscle strength group(n=2,000) and the low muscle strength group(n=1,273) according to the handgrip strength. There was a significant difference in general characteristics, diet habits, and health behavior according to the muscle strength status. The normal muscle strength group had a higher total score of KHEI and a subtotal score of 「adequacy」 items. But there was not significant difference in the 「moderation」 items. For the 「balance of energy intake」 items, the normal muscle strength group had a higher subtotal score than the low muscle strength group only in among women. The prevalence of low muscle strength decreased in the highest quartile of the adjusted KHEI total score(p for trend=0.08). As a result of this study, it was found that KHEI was significantly associated with muscle strength. This study result can be used to provide dietary guidelines for the improvement of muscle strength in the elderly based on each item of KHEI and sex.

Recently, Korean society has emphasized the level of digital information usage in each individual's life due to the advent of the intelligent information society and the great digital transformation. The purpose of this study is to examine how the level of digital information usage of people with disabilities affects their satisfaction with life and whether social support moderates the relationship between the level of digital information usage and life satisfaction. This study analyzed the data of 2,200 people with disabilities taken from the 2020 Survey on the Digital Divide conducted by the National Information Society Agency. The results of the analysis suggest that people with disabilities have a higher degree of satisfaction when they are employed and have a higher than average monthly income and higher levels of digital information usage and social support. In addition, the results show that social support played a negative moderator role between the level of digital information usage and life satisfaction. This shows that life satisfaction can increase when the disabled frequently use digital devices and technologies in their daily lives without relying on social support, and suggested the need for intervention in policies and practice sites.

Consumers of web novels read online reviews in order to decrease uncertainty when purchasing a web novel. This study examines the types of messages (factual or evaluative) that consumers find more useful and verifies the moderating effect of individual analytical decision-making style levels on differences in usefulness evaluation. Based on the tendency to acquire objective information, the usefulness of factual online reviews was expected to be higher in the context of buying experience goods, such as a web novel. Levels of analytical decision-making styles, which were classified based on individual perception, are also expected to affect the usefulness evaluation of reviews. Experiments 1 and 2 were repeatedly conducted to examine whether consumers think factual reviews are more useful than evaluative reviews. In particular, Experiment 2 was conducted to simulate the circumstance of selecting a romance web novel and demonstrated that reviews have a significant effect on messages and decision-making styles. The interaction effect between analytical decision-making style levels and review message types was also confirmed in Experiment 2. The results of this study can help researchers and marketers comprehend the behavioral patterns of web novel readers when evaluating reviews and consuming experience goods.

The rapid increase in the use of mobile devices is changing consumers' online shopping behavior. However, the difference in the effect on the conversion rate according to the time when consumers switch from a small screen to a large screen has not been sufficiently studied. In addition, the differences in the effect of device conversion on purchase performance according to the characteristics of each country's infrastructure have not been sufficiently studied. Against this background, this study aims to analyze whether the timing of switching from mobile devices to PC devices and the country's mobile Internet penetration rate are moderating the positive effect of device switching on purchase performance. For empirical analysis, Google Merchandise Store data was collected and 101,466 data from 130 countries were analyzed with a multilevel model. As a result of the analysis, consumers' device switching (i.e., mobile to PC) had a positive effect when it occurred in the middle of the consumer journey. However, it was analyzed that when device switching occurred at the later stage of the consumer journey, it had a negative effect on purchase performance. In addition, it was analyzed that the higher the mobile Internet penetration rate, the weaker the positive effect of consumer device conversion on purchase performance.
