The research was conducted on 238 marine sports participants by clarifying the relationship among self-efficacy, sociality, and organization culture, to eliminate the organizational(home, school, club, workplace, etc.) culture maladjustment phenomenon which is caused by personal stress, the lack of physical activity, and the lack of sociality due to the rapid change of modern society and enhance sociality, adjustment to society and the lack of creativity due to the rigid hierarchy and contribute to organization culture through marine sports among sports which we enjoy with nature. Firstly, according to general self-efficacy, and social characteristics of the organizational culture and the gender differences in higher than women in all sub-variables of the sub-factors of self-efficacy and self-regulation, sociability, organizational culture, sub-culture and develop cultural factors agreed man showed that in the sub-factors of organization culture showed that the development of high culture and hierarchical culture in the age of 20s. Secondly, in terms of the effect of self-efficacy of marine sports participants on sociality, it is found that self-regulation and level of difficulty positively influence on the culture of agreement, the culture of development and the culture of hierarchy. Lastly, in terms of the effect of self-efficacy of marine sports participants on organizational culture, it is shown that self-regulation has positive influence on the culture of agreement, the culture of development and the culture of hierarchy.

Objective: The purpose of this was to find out the muscle activity of the quadriceps femoris by gender when sitting on a chair while performing stairs gait (US; Up-stairs, DS; Down-stairs). Method: 13 male subjects (age: 22.00 ± 1.68 yrs, height: 174.85 ± 6.10 cm, weight: 68.15 ± 9.83 kg) and 15 female subjects (age: 21.17 ± 1.58 yrs, height: 168.20 ± 5.55 cm, weight: 55.73 ± 6.94 kg) participated in this study. The study used wireless three channel EMG. Results: In this study, there was no gender difference in quadriceps femoris activity during the US and DS periods, and there was no significant difference between the male group before and after postural maintenance during the US and DS periods. The quadriceps muscle of the female group also did not show a significant difference before and after US sitting. However, the vastus medialis muscle activity during DS in the female group was significantly lower after application than before application of maintaining a sitting posture (p<.05). There was no interaction effect between the 15-minute sitting position application and gender. Conclusion: Our results demonstrate that sitting in a chair affects the transient functioning of the quadriceps muscle in women. Therefore, emphasize the need for active rest when sitting in a chair for long periods of time.

Bromotopsentin (BSM) is a bisindole alkaloid compound, which is recognized as a metabolite of the marine sponge Spongosorites sp. In this study, the antioxidant activity of BSM was investigated. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, the trolox equivalent antioxidant capacity (TEAC) assay, the superoxide radical scavenging (NBT) assay, the lipid peroxidation and hydroxyl radical-induced DNA damage assays were carried out to evaluate the antioxidant activity of BSM. It was found that BSM had stronger scavenging activity on the stable free radical DPPH and superoxide radical than L-ascorbic acid with an $IC_{50}$ value of 62 and 64 ${\mu}M$, respectively. The TEAC value which indicated the total antioxidant capacity of BSM was about 0.8, which was also stronger than L-ascorbic acid. About 1.3 ${\mu}M$ of BSM induced 50% inhibition of lipid peroxidation. 60 nM of BSM exhibited a significant protective activity against DNA strand scission by hydroxyl radical on pBR322 DNA. Taken together, we suggest that BSM possesses strong antioxidant activity, and could be a valuable new addition to the list of anti-aging chemotherapeutic agents.
