Polymer thick film capacitors were successfully fabricated by using ink-jet printing and screen printing technology. First, a bottom electrode was patterned by ink-jet printing of a nano-sized silver ink. Next, a dielectric layer was formed by the screen printing, then a top electrode was pattern by ink-jet printing of a nano-sized silver ink. The printed area of the dielectric layers were changed into 2×2㎡ and 4×2㎡, and also the area of the electrodes were patterned with 1×3㎟ and 1×3㎟. The thickness of the printed dielectric layer was ranged from 1.1 to 1.4㎛. The analysis of capacitances verified that the capacitances was proportional to the area of the printed electrode. The capacitances of the fabricated capacitors resulted in one third of the calculated capacitances.

This study aims to empirically investigate the association between residual audit fees and firm operational efficiency, using a sample of non-financial firms listed on the KOSPI and KOSDAQ markets with December fiscal year-ends from 2003 to 2022. The findings indicate a significant negative relationship between residual audit fees and operational efficiency. This suggests that higher residual audit fees are associated with lower operational efficiency, reflecting auditors' private evaluations of auditee accounting system quality. Robustness checks and additional analyses, including analyses of firms with high operating uncertainty, consistently support this finding. Furthermore, the results remain consistent even when controlling for traditional accounting quality variables. This study contributes to the literature by validating residual audit fees as a proxy for overall accounting quality within the Korean context and by bridging financial and managerial accounting perspectives.

이 연구는 미국의 플랜 콜롬비아(Plan Colombia) 원조 과정에서 나타나는 일방주의적 반마약정책을 탐구한다. 이 연구는 2000년 6월 21일 있었던 제106대 미국 상원의원들의 플랜 콜롬비아에 대한 투표 및 의제설정을 분석함으로써 일방주의적 반마약정책을 코카 네이티비즘(Coca Nativism) 그리고 페리퍼럴 에어리얼리즘(Peripheral Aerialism) 두 개념으로 분석한다. 첫째, 코카 네이티비즘은 미국이 국내 마약문제를 해결하는 데 있어서 수요 보다는 공급의 해결을 우선시 하는 원칙이다. 즉, 미국 정부는 국내 마약 문제를 논의할 때, 국외 마약 생산 및 밀매 국가들을 단호하게 비판하고 반면에 미국 국민들을 희생자로 인식한다. 둘째, 페리퍼럴 에어리얼리즘은 미국의 반마약정책에서 나타나는 공수 기동성(air mobility) 중심의 간접적 군사원조원칙이다. 예컨대, 헬리콥터 및 장비, 인력, 정보, 훈련 지원 등을 바탕으로 한다. 이 연구는 미국의 콜롬비아 원조정책과 군사행동이 미국의 국내 마약문제 해결을 최우선 고려사항으로 하고 있고 이는 미국 일방주의 외교정책의 핵심 동인임을 주장한다.

The relationship between ethical consumption and conventional civic engagement has been underexamined in terms of individual differences in psychological factors. In fact, existing work in this area has been conducted in Western societies, even though the use of ethical consumption as a civic practice is not a phenomenon limited to certain areas. To set out to address the gap in literature, the current study examined the link between ethical consumption and civic engagement in South Korea. In particular, it focused Person and Thing Orientations, which have been known to stimulate individual differences. For this goal, an extensive online survey (n = 500) was conducted. The findings showed that ethical consumption correlated positively with public and private civic engagement, which echoed the results of several previous studies. Moreover, the relationships between ethical consumption and public and private civic engagement were moderated by Person and Thing Orientations, such that ethical consumers higher in Person and Thing Orientations were likely to be more engaged in public and private civic engagement. However, a simple slope analysis revealed that the positive relationship between ethical consumption and public engagement was not statistically significant among consumers lower in Person Orientations. Implications were discussed.

Based on the perspective of considering consumer boycotts as one type of civic engagement, this study explored the impacts of the critical involvement of political information on consumer boycotts and the mediating effects of political trust and community participation. For this purpose, two surveys were conducted against 463 foreign participants and 164 Korean participants to test the research hypotheses. For the analysis, structural equation modeling was employed. The results indicate that the direct effects of the individuals’ political involvement were not significant, but it is revealed to have indirect effects on consumer boycotts through political trust or community participation. The interesting point is that community participation is revealed to be the key factor of political participation by showing its direct and indirect effects in both samples. These findings not only support the alternative views of boycotts as civic engagement, these also offer a fresh perspective by showing the process and the mechanism of the connection among the critical involvement of political information, political trust, community participation, and consumer boycotts.

Teaching practices are the most significant in school education activities, so it is necessary to find structural relationships between influential factors of teaching practices. Previous studies are not implemented under the assumption that teaching career can make differences in teachers perception. Therefore, this study will examine the structural relationships between influential factors of teaching practices, such as teachers`` perceived principal``s transformational leadership, teacher efficacy, teacher collaboration, and their teaching practices in each teaching career stage. This study found several findings. First, for Kyunggi-do teachers, teachers`` perceived principal``s transformational leadership can affect teaching practices via teacher efficacy and teacher collaboration. Second, teacher efficacy consistently influences almost teaching practices regardless of teaching careers. Third, influential factors of teaching practices were different by their teaching years. For teachers with less than five teaching years and teachers with more than ten teaching years less than 20 teaching years, principal``s perceived transformational leadership, teacher efficacy and teacher collaboration affect their teaching practices. However, when teachers with more than five teaching years less than ten teaching years implement teaching practices, principal``s perceived transformational leadership was not a significant factor. For teachers with more than twenty teaching years, teacher collaboration did not affect their teaching practices.

This study explores the factors influencing the adolescents’ exposure to harmful contents (violent content, sexual content, insulting others, violation on social value) and cyber-delinquency. Especially this study focuses the effectiveness of parental mediation and peer norms and pressure. The major findings of this study are as follows. First, while parental mediation has not effects, peer norms and pressure have significant effects towards adolescents’ exposure to harmful contents on Internet. However, there are interactive effects on the factor of relationships with parents and parental restrict mediation. Also, peer relationships and peer pressure have interactive effects on exposure to harmful contents. Second, increasing peer pressure and exposure to harmful contents augment adolescents’ cyber-delinquency. These results suggest that the parental mediation should apply under varying relationship conditions and the roles of peer norm and pressure are most explaining to adolescents’ online behavior.

Most of prior studies on management overconfidence have reported that overconfident managers have negative impacts on the firm. However, there are some studies claiming that there is no evidence that overconfident managers undermine corporate value, instead, they achieve innovative success by boldly investing in innovation. This paper plans to examine the effect of overconfident management on the firm information environment and try to find out the benefits of overconfident management. Prior studies have reported two opposite directions on the effect of overconfident management on the corporate information environment. Overconfident managers may distort financial reporting and/or conservative accounting tends to weaken if earnings forecast becomes difficult to achieve or investment returns fall short of expectations. But there are studies which claimed that overconfident management can improve the information environment; these managers are more inclined to voluntarily disclose and provide specific earnings forecast. Kramer and Liao (2016), who carried out direct studies on the association between overconfident management and financial analysts’ forecast properties, reported that financial analysts’ earnings forecast accuracy is higher and forecast dispersion is smaller in overconfident management companies. Wei and Zhang (2016) analyzed the information role of overconfident managers in terms of mitigating information asymmetry among investors and found that financial analysts’ earnings forecast dispersion is small, broader investor base is formed and information asymmetry between investors is mitigated. This paper plans to empirically examine the informational role of overconfident managers in terms of stock price informativeness. Stock price informativeness is often measured as a future earnings response coefficient(FERC) or stock price synchronicity. If overconfident magement weakens information disclosure, for example, distorting or obscuring the financial information too much, then investors may not have enough information to predict the firm’s future prospects and place a little weight on the corporate information in forming a future profit expectation. In this case, it is expected that overconfident management have relatively high stock price synchronicity level and low FERC. On the other hand, overconfident management have strong willingness to disclose voluntarily, conduct the accounting with which the investors are able to easily evaluate future prospects and send a signal to the market that they are firmly carrying out long-term investment projects to make the investors collect more firm-specific information. In this case, there exists a possibility that stock price informativeness will be improved. This paper empirically analyzed the effect of management’s overconfidence on FERC and stock price synchronicity of the non-financial companies listed on KOSPI and KOSDAQ market between 2004 and 2015. This paper used the measurement of overconfident management of Schrand and Zechman (2012). FERC was estimated using a standard model used in the field of accounting, and the stock price synchronicity was measured relying on Piotroski and Roulstone(2004). For the robustness of the results, double clustering at the company and year level and control of the company fixing effect were conducted to estimate the standard error of the regression coefficient. As a result of the analysis, it was found that the companies with overconfident management have an incremental increase in FERC and a lower stock price synchronicity. This implies that the more overconfident management is, the more likely to use value-relevant firm-specific information in the market. This study contributes in the following aspects. First, it shows that the effect of overconfident management in the information environment could be a benefit to the company. Second, they have tried to explain the relationship between the stock price and earnings in
