Objectives : The purpose of this study aimed to investigate that dieckol - isolated from Ecklonia cava - supplementation can improve cognitive ability in mice. Methods : 48-male mice(6 weeks old) were divided into four groups; High-Dieckol group(n=12), Low-Dieckol group(n=12), Placebo group(n=12), Control group(n=12) and they were administered orally 5 days per week for 4 weeks at the same time. We performed Morris water maze test, Passive avoidance test, Blood serotonin analysis. And there was examined on neurogenesis in dentate gyrus of hippocampus using 5-bromo-2'-deoxyuridine (BrdU) to label proliferating cells. Results : The results are as follows; As a Morris water maze results, Trial duration was significantly decreased in high dieckol group comparing to placebo group and control group. Distance to target was significantly decreased in high dieckol group and low dieckol group comparing to placebo group and control group. Mean speed was significantly low in high dieckol group comparing to low dieckol group, placebo group and control group. As a Passive avoidance test results, latency time was significantly long in high dieckol group comparing to low dieckol group, placebo group and control group. BrdU cell count was significantly high in high dieckol group comparing to low dieckol group, placebo group and control group. Conclusions : As a conclusion, it is considered that dieckol supplementation might improve learning and cognitive ability.

As people have gained leisure time and become more interested in sports, various industries catering to these sports, including aquatic and underwater activities are growing. Many people are getting into scuba diving, where people can explore the sea at depths of more than 40-meters. Despite the increasing demand, there are limited studies on the sport. This study aims to provide basic research on materials suitable for developing technical scuba diving suits by analyzing several areas, such as design, material, sewing patterns, etc. The following trends were observed in all wetsuits: closure designs, ergonomic patterns, practical and functional details. Neoprene was the primary material of diving suits, and various functional materials were attached to the outer fabric or lining. The seam technique which minimized water contact and improved durability was sewing. Various techniques were also applied, such as flatlock stitching, GBS, LFS, etc. Subsequent studies shall investigate consumer preference etc. and other aspects, and continue to allow for the research and development of technical diving suits.

복합재료는 현재 항공-우주산업, 스포츠와 레저 산업에서 널리 사용되고 있으나, 흡습에 의해 기계적 성질이 저하하는 문제점을 가지고 있다. 본 연구에서는 이러한 문제점에 대한 규명을 위해 $80^{\circ}C$의 수 환경(담수/해수)에서 $100{\sim}200일$ 동안 침지/침지 - 건조한 시편으로 전단강도를 평가하였다. 그 결과, 전단강도의 하락은 초기에는 수지부의 흡습과 실란부의 흡습에 의한 물성저하 그리고 나중에는 실란부와 섬유와의 기계적 결합의 파괴가 주요원인으로 판단되었다. 결론적으로, 복합재료 내의 수분으로 인해 비가역구간을 넘어서게 되면 수분으로 인한 계면 파괴가 일어나 전단강도 회복이 어려워지는 것으로 판단된다.
