This study intends to test the effect of cyber victimization on cyber offending and investigates which variables operate moderating effects. This study uses six moderating variables such as low self-control, attitudes toward cyber delinquency, parental support, peer support, self-esteem, and the perceived opportunity of cyber delinquency. Using data from 353 elementary, middle, and high school student in Kyunggi area, the study tests the interaction effects of cyber victimization and moderating variables on cyber offending. Results show that the interaction effect between cyber victimization and low self-control is not significant. However, the interaction effect between cyber victimization and attitude towards cyber delinquency is positively significant. In addition, the interaction effect between cyber victimization and peer support is negatively significant, while the interaction effect between cyber victimization and parental support is positively significant. It is also found that the interaction effect between cyber victimization and self-esteem is negatively significant. It is revealed that the moderating effect of the perceived opportunity is the most significant. The policy implications are discussed.

The protein back-extraction processes were discussed from the viewpoint of the micelle-micelle interaction. Bovine serum albumin (BSA) suppressing the cluster formation of reverse micelle (positive value of ${\beta}pr)$ has the high back-extra cted fraction (Eb), but cytochrome c enhancing the formation of reverse micelle (negative value of ${\beta}pr)$ has the low back-extracted fraction, relatively. We have also examined quantitatively the effects of alcohol addition and protein solubilization on the percolation process of reverse micelle. The alcohols suppressing the formation of micellar cluster (high values of ${\beta}t)$, remarkably improved the back-extraction rates of BSA and cytochrome c. The values of ${\beta}t$, defined by the variation of percolation process, and the back-extraction behavior of proteins have a good linear correlation. These results indicate that the micelle-micelle interaction or micellar clustering plays an important role in the back-extraction process of proteins.
디지털 저작권침해 행위에서 상황행위이론의 적용을 통한 자기통제와 처벌억제의 조절효과: 다운로드와 업로드 행위의 비교

이 연구는 상황행위이론을 디지털 저작권침해의 다운로드와 업로드 행위에 적용함에 있어 자기통제력과 처벌억제의 통제작용을 살펴보았다. 상황행위이론에 따르면 개인의 도덕성은 높은데 도덕규칙이 약한 환경일 때는 자기통제력이, 도덕규칙 환경은 높은데 개인의 도덕성이 낮을 때는 처벌억제가 범죄에 통제요인으로 조절효과를 갖는다고 보았다. 이에 본 연구는 서울시 재학중인 317명 대학생을 대상으로 다운로드와 업로드 행위로 나누어 각각 상황행위이론의 논의를 상호작용효과 분석을 통해 검증했다. 분석결과 다운로드의 경우는 도덕성이 높지만 도덕규칙이 낮은 경우에서 자기통제력이, 그리고 도덕규칙이 높지만 도덕성이 낮을 때 처벌억제가 유의미하게 작용할 것이라는 상황행위이론을 지지하지 못했고 상호작용효과 결과가 유의미하지 않았다. 그리고 업로드의 경우는 상황행위이론과는 달리 도덕성은 높지만 도덕규칙이 낮은 경우에서 자기통제력이 업로드를 통제하기보다 오히려 유발하는 요인으로 작용하는 것을 제시했고, 또한 상황행위이론과 반대로 도덕성은 높지만 도덕규칙이 낮은 경우에서 처벌억제가 조절효과를 갖는 것을 제시했다. This study test a situational action theory for explaining online download and upload digital piracy and examines the moderating effect of self-control and punishment. Then it tests the moderating effect of self-control in high morality and low moral rule environments and tests the moderating effect of perceived punishment in low morality and high moral rule environments. Using data from 317 college students in Seoul, In case of download, results show that self-control does not control the effects of high morality and low moral rule on it. In addition, it is found that perceived punishment does not control the effects of low morality and high moral rule on it. In case of upload, results show that self-control does not control but increase the effects of high morality and low moral rule on it, while perceived punishment controls the effects of high morality and low moral rule on it.

This experiment was conducted to determine economic application method of Yakto among 6 application method: amount of Yakto application 3 plots(70ℓ, 25.5ℓ, 13.3 ℓ/kan), and added side dressing(3ℓ/kan) each plot. The reduced Yakto application(25.5ℓ/kan) with side dressing(3ℓ/kan) showed similar root diameter, fresh weight of roots and yield of good seedlings to standard Yakto application(70ℓ/kan). And also this application method of Yakto gave similar content of Ca and Mg, but the lower content of N, P, K in roots to standard Yakto application(70ℓ/kan). These suggested that 25.5ℓ Yakto application added side dressing(3ℓ/kan) per kan might be economical application method of Yakto.

This study aims to reveal the effects of major theories upon juvenile text bullying. It focuses on three main factors of individual propensity, social environment, and opportunity, out of which we respectively derived three major variables of low self-control, contact with text-bullying friends as a social learning factor, and finally mobile media opportunity. Furthermore, three factors each need to be functioned integratively for a better explanation of mobile text bullying so that we examined not only the independent effects of each theoretical factor but also the interaction effects among these three factors. We sampled 640 middle school students in Seoul possessing their own mobile media devices and found that those three factors of individual propensity, social learning and mobile media opportunity appeared to be the major reasons why they commit mobile text bullying. In addition, we found that the interaction effect between the low self-control and media opportunity was statistically significant. However, other interaction effects, such as one between low self-control and social learning and the other between social learning and opportunity, did not appeared to be statistically significant. Even if this is the case, we still found that the three-way interaction effects among these three are statistically significant implying that the mobile text bullying can be explained when we consider these three factors simultaneously.
