This paper presents a series of path models that were developed to test whether financial risk tolerance mediates the association between the following four variables and investing behavior: (a) male and married, (b) female and married, (c) male and single, or (d) female and single. Data for this study were obtained from a proprietary consumer survey of risk-tolerance attitudes. Four path models were developed to test relationships among the variables in 2008, 2009, 2010, and 2011. These years were chosen to represent the depth and recovery periods in the Great Recession. The total number of respondents was 29,641. Findings showed that financial risk tolerance was positively associated with risky investing behavior (i.e., equity ownership) in each of the four periods. The associations among the gender-marital status variables and investing behavior were mixed; however, findings did indicate that risk tolerance mediates these relationships by sometimes amplifying and occasionally attenuating risky behavior. Based on the findings, implications and limitation are presented.

Single overload fatigue tests with overload sizes ranging from 50% and 100% have been performed to investing ate the fatigue crack growth retardation behavior. A modified and experimental method of Willenborg's model for prediction of crack growth retardation behavior has been developed, based on evaluations of equivalent plastic zone size (EPZS) changing its size along the overload plastic zone boundary. The minimum crack growth rates of each overload size are linearly decreased with overload size increasing, but fatigue lives extended by single overload are increasing much more unlike the crack growth rates. Comparisons of crack growth behavior predicted by EPZS model and Willenborg model have shown that the EPZS model accounts for overload effects better than Willenborg model. These effects include delayed retardation, large retardation region, minimum crack growth rate, and the increase rate of crack growth rate in the region crack growth rate recovered.

본 논문의 플랫폼이라는 자산의 관계특이성으로 인한 한국형 무선인터넷 플랫폼인 WIPI가 도입되기 이전에는 단말기제조사가 아닌 이동통신 3사가 주체가 되어 서로 다른 무선인터넷 플랫폼을 개발${\cdot}$사용하는 것이 균형이었으나, 정부가 주체가 되어 WIPI를 도입한 이후에는 표준화로 인한 이동통신사의 비용감소 및 호환성 효과가 전유성(專有性) 효과를 상쇄할 때에만 WIPI 사용이 바람직한 사회적 균형으로 달성된다는 것을 보여주었다. 즉, 사회적 균형이 정책에 의해 동일한 플랫폼(WIPI)으로 옮겨졌을 때에는 이동통신사의 투자유인이 감소할 수 있으며, 이로 인한 시장실패가 발생할 수 있으므로 이에 대한 정책대안이 요구된다는 것을 알 수 있었다.

We apply Return Dispersion Model by calculating CSAD (Cross-sectional standard deviation of return) and State Space Model to identify herding behavior in the period of pandemic (H1N1 and COVID-19). Employing data from TEJ and Data Stream, this paper examines whether the herding behavior is existing in Vietnam and Taiwan stock market, especially during pandemic influenza. We compare the differences in herding behavior between frontier and emerging markets by examining different industries across Vietnam and Taiwan stock market approaches. The results indicate solid evidence for investor herd configuration in the various industries of Vietnam and Taiwan. The herding impact in the industries will be greater than with the aggregate market. The different industries respond differently to influenza pandemic panics through uptrend and downtrend demonstrations. Up to 12 industries were found to have herding in Vietnam, while Taiwan had only 5 of 17 industries classified. Taiwan market, an emerging and herding-level market, has changed due to the impact of changing conditions such as epidemics, but not as strongly as in Vietnam. From there, we see that the disease is a factor that, not only creates anxiety from a health perspective, but also causes psychological instability for investors when investing in the market.

The purpose of this study is to examine an immoral effectiveness decrease by information access monitoring between ethical dilemma and unethical information-sharing behavior. Firms are raising the demand of confidential information management and are highlighting the ethical awareness of organizational members. The individuals in organization are concerned information sharing for future-oriented social networking. To prevent their immoral behavior, Firms should consider investing the information access monitoring. This system is aiming at log verification of movement, storage and deletion on information and will reduce an ethical conflict and unethical behavior on employees. I used the structural equation methodology for this empirical study. The research model constructs the voluntary and involuntary dilemma of information sharing on the two independent-variables, the unethical information behavior and the improper networking reinforcement on the two dependent-variables and the information access monitoring the one mediating-variables. This model tests the power effect of direct path, indirect path and total path. According to the study, the two ethical dilemma of information sharing provided a high influence to the unethical sharing action and to the inappropriate social networking strengthens. However, the mediating role of information access monitoring shows the effect weakens of independent and dependent variables. Thus, the mediating variables appeared to be important for the controlling role of an unethical behavior and improper social networking. Ultimately, The firms will need to invest the information access monitoring for a compulsory ethics behavior of organizational members. In addition, this can hinder networking enhancements for future opportunistic behaviors.

The study investigates the role of commodity prices and tax purpose recognition on bitcoin prices. Since the introduction of bitcoin in 2008, emphasis has focused on economists, policy-makers and analysts drastically increasing bitcoin's accessibility and commodity values (Dumitrescu & Firică, 2014). This study employs GARCH and EGARCH from ARCH/GARCH family on daily nature data. We measure the volatile behavior of bitcoin by employing auto-regressive conditional heteroscedasticity model with the aim to explore the relationship between major commodities and bitcoin volatility. We focus on major commodities like gold, silver, platinum, and crude oil to be regressed with bitcoin. The daily prices of commodities were retrieved from www.investing.com and bitcoin prices from www.coindesk.com for the period from 29April 2013 to 16 October 2018. Results confirmed the currency's long-term volatile behavior, which is due to its composition and market dynamics, whereas the existence of asymmetric information effect is not confirmed. Tax recognition by other countries may in future help in controlling the volatility as bitcoin is not a country-specific security. But, only silver impacts on volatility in comparison to oil prices and platinum, which is due to its similar features with gold. Eventually, bitcoin can be used for risk diversification and money making.

Idol goods refer to products such as cups and towels, or mementos or souvenirs that are manufactured to gratify the desires of fandom and may include the facial images of a star. The objective of this research was to explore the purchase behaviors of K-pop idol goods. Two hundred and sixty female idol goods purchasers in their twenties participated in an online survey. Cheering tools were the most often purchased idol goods, followed by idol slogans and dolls. To investigate the difference in idol goods' attributes they considered when shopping, respondents were divided into three purchase groups based on their annual total expense for purchasing idol goods. There were significant differences among light, medium and heavy purchasers in terms of goods' price, practical features, and scarcity. The light shopper group was majorly guided by price and practical features as compared to the other two groups, and heavy shopper group was majorly guided by scarcity attribute than in the other two shopper groups. The more they identified their favorite idols, the more they worked hard, the higher their income, the higher the expenses of investing in idol products, the more likely they were to repurchase idol goods. In term of post-purchase behavior of idol goods, most idol goods purchase by fans were stored rather than used, and few indicated that they purchase two identical idol goods for use and storage.
