This study aimed to analyze the causality of hairtail prices among import and domestic distribution channels using a Vector Error Correction Model(VECM). The results are as follows. First, since the ADF unit-root test suggests that each of the price variables, apart from retail price, has a unit root, the price variables should be 1st-differenced to secure the stability of the prices. Next, through the Johansen co-integration test, it was discovered that there are long-term relationships among the price variables. On the basis of the co-integration test, VECM analysis shows that the producer price has a long-run balance with the import and wholesale prices. In particular, when the prices deviate from the balance, the producer price dynamically adjusts to return to the long-term relationship among prices. It also indicates that the producer price has an impact on the import, wholesale, and retail prices in the short-term, and the import price has an influence on the producer and wholesale prices. In addition, the impulse response analysis demonstrates that the impulse of import and producer prices has a lasting impact on each of the prices.

본 연구는 정보기술의 사용(Usage)과 수용(Adoption)을 예상하는 목적보다는 웹 기반 협동합습 시스템사용 의도와 사용행위에 영향을 미치는 변수들을 폭 넓게 이해하고, 실질적으로 활용 할 수 있는 변수를 찾는데 목적이 있기 때문에 분해된 계획 행동 이론(Decomposed TPB)을 기반 하였고, 분해된 변수들 중 일부분(지각된 유용성, 지각된 용이성, 명시적 영향, 암시적 영향)과 웹 환경의 중요 요소인 '흥미성' 을 포함하여 사용의도(Use Intention)에 영향을 미치는 변수들을 2개 대학의 대학생 256명을 대상으로 자료를 수집하여 실증 분석하였다. 연구결과 다차원으로 분해된 일부 변수들 중 태도적 믿음 변수인 '지각된 용이성'을 제외하고 분해된 모든 변수가 사용의도에 긍정적 강한 영향을 미치고 있음을 알 수 있었고, 특히 주관적 규범(명시적 영향, 암시적 영향)변수는 준거집단을 통해서 웹기반 협동학습 시스템에 대한 행동의도나 인지에 영향을 줄 수 있는 중요 변수로 나타났다. 이러한 결과는 준거인이 되는 팀장은 팀원 및 학습자들과의 상호작용(협동학습을 통한 화상토론, 게시판정활동, 오프라인 정기 모임, 동영상 동시 시청)과 팀원 관리 및 운영하는 역할이기 때문에 새로운 정보 기술 및 시스템 사용 권유를 하거나, 직접 기술사용을 하는 주변 분위기는 협동합습에 참여한 학습자들에게 조금이나마 영향을 줄 수 있음을 추측 해 볼 수 있고 영향력 있는 중요변수임을 제시하였다.

This study attempted to examine a theoretical framework which synthesizes risk attitude, type of investment management and investment behavior and to provide the specific investment strategy by analysing several variables which have effect upon the investment behavior. The results of this research were as follow : 1. Risk attitude had significant differences by the variabels such as age, sex, education, income and debt/asset ratio. Also the type of investment management was influenced significantly by the variables such as age, education, occupation, income, total asset, debt/asset ratio, achievement motivation and risk attitude. The ratio of risky asset holdings was affected by the variabels such as age, education, occupation, housing ownership, income, total asset, debt/asset ratio, achievement motivation, risk attitude and type of investment management. 2. Among several variables affecting the ratio of risky asset holding risk attitude, education, type of investment management, debt/asset ratio and achievement motivation had direct effect on it. Besides age had indirect effect through risk attitude and age, achievement motivation and risk attitude had indirect effect through the type of investment management. 3. The results of this study showed that causal relation between input, throughput and output can be applied to household's investment behavior and the concept of risk or risk attitude can be applied to other fields except household's investment. Also it could be attributed to provide the investment strategy for improving level of household's financial well-being.

This study aims to analyze causalities among Hairtail prices by distribution channel using a vector autoregressive model. This study applies unit-root test for stability of data, uses Granger causality test to know interaction among Hairtail Prices by distribution channel, and employes the vector autoregressive model to estimate statistical impacts among t-2 period variables used in model. Analyzing results of this study are as follows. First, ADF, PP, and KPSS tests show that the change rate of Hairtail price by distribution channel differentiated by logarithm is stable. Second, a Granger causality test presents that the producer price of Hairtail leads the wholesale price and then the wholesale price leads the consumer price. Third, the vector autoregressive model suggests that the change rate of Hairtail producer price of t-2 period variables statistically, significantly impacts change rates of own, wholesale, and consumer prices at current period. Fourth, the impulse response analysis indicates that impulse responses of the structural shocks with a respectively distribution channel of the Hairtail prices are relatively more powerful in own distribution channel than in other distribution channels. Fifth, a forecast error variance decomposition of the Hairtail prices points out that the own price has relatively more powerful influence than other prices.

The purpose of this study is to examine the longitudinal causal relationships between maternal parenting stress and parenting attitudes. Relevant data from mothers with infants aged from 2 to 4 years of age was gathered from the Panel Study of Korean Children were analyzed by means of Latent Growth Modeling. The findings are as follows, First, levels of parenting stress increased whereas the extent of positive parenting attitudes decreased as children grow older. Second, the initial value of parenting stress was observed to have a negative effect on the initial value of positive parenting attitudes. Third, those mothers who generally have faster speeds of increasing parenting stress tend to have faster speeds of decreases in positive parenting attitudes. What this study clearly revealed is that the positive parenting attitudes of mothers with infants tend to improve when the mothers try to efficiently deal with their parenting stress by either acquiring appropriate parenting knowledge or receiving support from their families and communities.
