Inbreeding depression may be an avoidable phenomenon for abalone culture. However, only a few studies were carried out on inbreeding depression. In the present study, to demonstrate inbreeding depression in growth trait of Pacific abalone, H. discus hannai, inbreeding and outbreeding families were produced in 2010. Inbred and outbred families from each experiment were reared in same tank until 10 month for the same breed environment. The individual of inbred and outbred were distinguished by paternity test using microsatellite DNA. The shell length between inbred and outbred families was compared. At the results, significantly higher shell length was observed in the outbred families at 10 mon (P < 0.05). These results indicate that inbreeding depression is obviously observed in growth traits in the first generation of full-sib family of the H. discus hannai.

Purpose: To estimate the prevalence and incidence of patellar tendinitis, to discover the patellar tendinitis in top level male volley ball players. Materials and Methods: Thirteen members of the male adult volleyball players were included in this study. From history and physical examination, 3 of the 13 players had patellar tendon pain associated with activity and were diagnosed as patellar tendinitis at the time of the study. Investigators were blinded about the injury status of the players. For all players, data such as age, volleyball experience, amount of training and competition hours were recorded. Results: Of the thirteen cases, two spikers complained pain on the lower pole of the patella, one setter on the upper pole. Conclusion: This findings suggest that patellar tendinitis in the volleyball players are influenced by the amount of the practice and their position. In most cases, the supervised control of the practice will reduce the overuse injuries in the volleyball players.

This article is for considering and looking through the meaning of Classic of Poetry(Shi jing) Hiku-ka of Kobayashi Issa before reviewing and adapting Classic of Poetry(Shi jing) in Eastern Asia. Issa wrote his works by using Hyanghwa-Gucheop in 1803, and he had adopted it as his creative works of Hikai absorbing Classic of Poetry(Shi jing) for about half a year. There has been no national study about this so far, and this study covered the aspects of Issa's adapting way of Classic of Poetry(Shi jing) in Japan and China. There have been several problems that the contents were limited to Guo-feng and there were no agreement of terminology as well among researchers. To overcome these limitations, therefore, this article aimed at all the works, rejected the view point as just a translation, and denominated this study as Haiku-ka. Above all, this study looked though Issa's Classic of Poetry(Shi jing) by splitting the aspects of Haiku-ka into borrowing topics and materials. In borrowing topics, the works with the topics of homesick and nostalgic parents stood out. Furthermore, annotations and understandings of Issa's original works were deeply involved. In borrowing materials, the original meanings in the works were transformed and changed or even reinterpreted by their own way. Eliminating sublime emotions, furious tone, and condemnation was main characteristic of Haiku-ka in Classic of Poetry(Shi jing). Besides, there were ways of exclusion of reasoning, deviating from the viewpoint of Sigyo(edification by poetry), not including moral senses. In other words, Issa used habits and impressions like the way of Haiku when he was doing Haiku-ka in Classic of Poetry(Shi jing). The meaning that Issa's Hiku-ka of Classic of Poetry(Shi jing) stood out compared to adaptation of Classic of Poetry(Shi jing) in Eastern Asia. Although Classic of Poetry(Shi jing) in Vietnam was transferred in the form of the poem in Vernacular, the meaning and contents were not changed. Moreover, the original works and characters in Joseon were not destroyed because Classic of Poetry(Shi jing) was not liberally translated but literally. However, Issa transferred the Classic of Poetry(Shi jing) in the form of the poem in Vernacular to reveal the value of popular ballads. This was a different adapting way of Classic of Poetry(Shi jing) from that in Eastern Asia.

Rape residue as green manure is an emerging alternative of chemical fertilizer to improve soil quality and crop productivity. Objective of this research was to evaluate the effectiveness of rape residue as green manure on reduction of chemical fertilizer and suppression of weed occurrence in rice-rape double cropping system. Greenhouse experiment was conducted with four treatments: the combination of rape residue and three different N application rates (0, 30 and 70% of recommended application rate (7.8 kg N $10a^{-1}$)) and 100% chemical fertilizer as a control. No difference in rice clum length was observed for all treatments, while panicle length was highest in a treatment of rape residue+70% chemical fertilizer (Rape+70%CF). In addition, rice grain weight at a Rape+70%CF treatment increased by 19% compared to the control. This treatment also reduced weed density and biomass by 58 and 53%, respectively, compared to the control. Our results suggest that use of rape residues as green manure is an environment friendly and effective way to reduce chemical fertilizer and to enhance crop productivity in rice-rape double cropping system in Korea.

The study aims to verify the effects of volleyball programs on the fitness and attention-intensive abilities of students with intellectual disabilities in middle school. Physical strength and attention concentration were analyzed to verify the effectiveness of the volleyball program. The volleyball program was applied to the experimental group three times a week, 90 minutes a week, a total of 36 times for 12 weeks. To verify the effectiveness of physical strength and attention concentration, the PPS-D intellectual disability student test and ATA concentration test were used to verify the effectiveness of attention concentration The six-minute walking figure related to cardiopulmonary functions was improved compared to those with intellectual disabilities who did not participate in the volleyball program, the report showed. We can see improvements in muscular function-related sit-ups and flexibility-related sit-ups compared to those with intellectual disabilities who did not participate, and significant changes have been seen in the distance of the place-wide jump related to net worth. We could also confirm that it had a positive effect on the improvement of selective attention concentration, and that the change in self-control, continuous attention, and selective attention among middle school students had a positive effect on the improvement.
