To determine optimal plant density of forage rape in southern areas of Korea, Velox, the highest yielding variety among seventeen introduced varieties of forage rape, was grown under five different plant densities. The results obtained are summarized as follows: 1. Yield components such as stem diameter, number of main stem,leaves, number of branches and number of branch leaves and fresh yield were highest at the plots with 50cm row spacing and 30cm plant spacing. 2. Dry matter yield, content of crude protein, IVDMD and digestible dry matter yield were highest at the plots of broadcasting. 3. Since plants under high density were high in plant length and small in stem diameter, contents of crude fiber such as NDF, ADF, cellulose and lignin were lowest at the plots of broadcasting.

This study empirically analyzes the economic validity of rape farmers. The analysis of economic evaluation is based on the benefit-cost analysis. Previous studies have undoubtedly expanded our understanding of the importance of substitution effects on a rapeseed for bio-fuels. However, earlier studies have mostly dealt with the concept of biodiesel's economics analysis, but this paper's attentions have been paid to the economic analysis of farm. The aim of this paper is suggesting the most appropriate policy brings about why farmhouses should cultivate the rape. To answer this question, this paper adopts a scenario analysis and the B/C ratio is used.

Effects of IAA on the elongation and cell wall hlysocidase activities were investigated in excised rape (Brassica napus L. cv. Yongdang) hypocotyl segments. IAA promoted the elongation of rape hypocotyl segments. In rape hypocotyls, the first 10-mm segments from the hook exhibited maximal elongation and the capacity of elongation was gradually decreased with increasing distance of each 10-mm from the hook. A good correlation has been obtained between the magnitude of endogenous growth and the activities of $\alpha$, $\beta$-glucosidase and $\alpha$, $\beta$-galactosidase. However, exogenous application of IAA did not seem to enhance the tissue with IAA resulted in acidification of the incubation medium. From these data, we can conclude that IAA seems to enhance elongation of the tissue segments, at least in part, by releasing hydrogen ion into cell wall, some of which may participate in the cell wall extension process, but does not seem to trigger the activation of $\alpha$, $\beta$-glucosidase and $\alpha$, $\beta$-galactosidase.

The purpose of this study was to investigate the relationship between internet pornography seeking and sexual violence(rape) myth acceptance attitudes in college students. The participants included 381 college students by a convenience sample method and agreed to participate in the study. Data were collected from September, 2 to September 14, 2012 and analysed using SPSS/PC Win 12.0 program. The major finding were as follows; The scoe of internet pornography seeking was 19.57 and the scoe of sexual violence(rape) myth acceptance attitudes was 9.68. There were significant differences in the internet pornography seeking according to sex, major, internet use time, experience, time, frequency, place, companion, reason of internet pornography contact, and the most sexual stimualting material. There were significant differences in the sexual violence(rape) myth acceptance attitudes according to sex, age, major, companion of internet pornography contact, the most frequently contacting internet pornography, and the most sexually exciting internet pornography. There was significant positive relationship between internet pornography seeking and sexual violence(rape) myth acceptance attitude.

Purpose: This study aimed to clarify the relationship between analysis of rape myths acceptance and gender role stereotype among university students. Method: First-year students at two three-year colleges in Jeonnam and two three-year colleges in Jeonbuk (n=406) were selected by convenience sampling. Of these, responses from 386 (95.8%) were analyzed. Result: Rape myths acceptance in male students was significantly higher than female students (t=5.400, p=.00). In terms of gender role stereotype, male students were significantly higher than female students (t=3.869, p<.001). The relationship between rape myths acceptance and gender role stereotype was in the middle range of correlation: male students' correlation coefficient was r=.520 (=p<.001), and female students' was r=.524 (p=<.001). Conclusion: The results indicate that university students' attitudes toward sex have not been properly established yet. Moreover, they highlight that in our society there still exists a male dominated social structure and inequality of sexes. To prevent sexual violation from occurring at the universities, it is necessary that programs to establish proper attitudes of students toward these two factors, should be developed and the results monitored frequently. In addition, cross sectional studies aimed at understanding rape myths acceptance and gender role stereotypes are needed.

This study was conducted to determine the effect of seeding times and mixture rates of oat and forage rape on the growth characteristics and forage yields during rest periods from March to June after the harvest of potatoes in potato cultivation fields located in the areas about 600m above the sea level in Jeju. The experiment was a split plot desist with seeding times(early, middle and late March) sown . at intervals of ten days from early March to late March as the nam plots and mixture rates as subplots, consisted of oat single(150kg/ha), forage rape single(15kg/ha), oat/rape mixtures 75 : 25% (112.5kg/ha of oat and 3.75kg/ha of rape), oat/rape mixtures 50 : 50％(75kg/ha of oat and 7.5kg/ha of rape) and oat/rape mixtures 25 : 75％(37.5kg/ha of oat and 11.3kg/ha of rape). The germination and establishment of eat and rape were not significantly different among seeding times and mixture rates. The plant heights were higher when seeded middle March compared to seeding times of early and late March. The growth stage of the oats seeded early March was dough stage, while that of oats seeded middle or late March was milk stage. The dry matter yields per ha were higher(p<0.05) when seeded middle March than those of seeding time of early and late March. The crude protein contents of rape single, mixtures and oat single treatments were 15.9, 12.4∼14.5 and 8.5％, respectively.

The present studies were carried out for three years from 2007 until 2009 to control nematode and to increase yield of cucumber by crashed-rape seed application at polyethylene film house. Crashed-rape seed has a lot of glucosinolate. Myrosinase decompose gulcosinolate into isothiocyanate and thiocyanate when crashedrape seed go to decay at soil. Those chemical compounds act on poison to nematode at soil. When the crashedrape seed treated at soil, an amount of thiocyanate at soil was risen up. Thiocyanate of plot treated with 200 and 400 kg crashed-rape seed per 10a was 30 and 40 mg/kg, respectively. Nematode(meloidogyne spp) population at soil was 13 to 17 nematodes per dried soil 300g. Yield of cucumber increased 6 to 15 percent to be compared with control. While, Nematode(meloidogyne spp) population of control plot were 463 nematodes per dried soil 300 g. This level was much higher than 150 nematodes which can be brought about injury to plant. Even if the more an amount of crashed-rape seed application, the higher yield of cucumber and control effect of nematode. Consider economical efficiency, 200 kg of crashed-rape seed per 10a was the most effective. Therefore, we suggest applying 200 kg of crashed-rape seed per 10a to control soil nematode when culture cucumber at plastic film house.

This study investigated whether judgments of sexual violence involving juvenile victims vary by history of victim's juvenile prostitution, victim's behavior conforming to stereotypes of an "ideal" victim, and relationships between victim and perpetrator. The study also examined the effects of participants' level of authoritarianism and rape myth acceptance on their judgments of sexual violence. A total of 335 participants(170 females, 165 males) in their 20s to 50s assessed the degree of victim blaming and perpetrator sentencing. This study examined the effects of participants' gender and age on the judgments of victim blaming and perpetrator sentencing, and the mediation effects of authoritarianism and rape myth acceptance. As a result, participants blamed the victim more and imposed a lighter sentence on the perpetrator when the juvenile victim did not conform to the image of an "ideal" victim of sexual violence as opposed to a "typical victim". They also blamed the victim more when the victim and the perpetrator met through a chat application than when the victim and the perpetrator had known each other. Male participants as opposed to female participants blamed the victim more, punished the perpetrator more lightly, and exhibited a higher level of authoritarianism and rape myth acceptance. The older the participants were, the more they blamed the victim and the higher they demonstrated rape myth acceptance. The effect of the participants' gender on the judgment of the perpetrator punishment was mediated by rape myth acceptance, and the effect of the participants' gender and age on the victim blaming was mediated by authoritarianism and rape myth acceptance.
