현재 우리나라에 서식하는 전복은 말전복(Haliotis gigantea), 까막전복(Haliotis discus), 참전복(Haliotis discus hannai), 시볼트전복(Haliotis sieboldii), 오분자기(Haliotis diversicolor superfexta), 둥근전복(Haliotis diversicolor diversicolor) 등 6종이 있고, 이 중 참전복은 가장 맛이 좋아 주로 날 것으로 또는 건제품 및 죽의 형태로 소비되는 고가의 중요한 연안 수산물이다. 특히, 전복은 식품학적 측면으로 볼 때, 오래 전부터 우리나라, 중국 및 일본 등지에서 상당히 귀하게 여기는 기능성 수산물이어서 시장 가치가 매우 높다고 할 수 있다.

In this paper, we describe the dynamic tumble-stability analysis of a seabed-walking robot named Crabster (CR200) in forward-incident currents. CR200 is designed to be operated in tidal-current conditions, and its body shape is also designed to minimize hydrodynamic resistances considering hydrodynamics. To analyze its tumble stability, we adopt the dynamic stability margin of a ground-legged robot and modify the definition of the margin to consider tidal-current effects. To analyze its dynamic tumble stability, we use the estimated hydrodynamic forces that act on the robot in various tidal-current conditions, and analyze the dynamic tumble-stability margin of the robot using the estimated results obtained for the various tidal-current conditions. From the analyses, we confirm the improved tumble stability of the robot according to the movement of the tumble axis caused by the supporting points of the legs.

The physicochemical characteristics of abalone meat aged in Kochujang at $20^{\circ}C$ were studied. Moisture contents of Kochujang, which contained raw, roasted, and steamed abalone, increased to 14.9, 10.7, and 7.8%, respectively, compared to control at day 1. The moisture contents of all products were equilibrated at 53.5% approximately after 2 weeks. Hunter's L, a, and b values increased in all products. Total microbial counts were 5.74, 5.70, and 5.83 log CFU/g in the products and increased to 0.28, 0.30, 0.11 log CFU/g, respectively, after 28 days storage at $20^{\circ}C$. After 8 days, the pH in the steamed abalone meat decreased gradually from 5.48 to 5.16 and the titratable acidity was the highest at day 14. Volatile base nitrogens of raw, roast, and steamed abalone were 1.4, 0.9, and 2.7 mg%, but the values in the Kochujang products were 14.0, 13.8, and 11.6 mg% at day 1, and 15.5, 13.3 and 11.3 mg% at day 8, respectively. Quality of the product prepared with steamed abalone was the most acceptable by sensory evaluation.

사용후 연료 건식 저장 용기가 낙하, 토네이도, 미사일, 홍수 및 지진으로 인한 사고에 대하여 전복이 발생되었을 때 강체 평면과 충돌에 의한 충돌 하중시의 구조 응력 평가하였다. 이를 위해 저장 용기의 무게 중심이 한계를 넘었을 때의 초기 전복 시작각을 무게 중심을 계산을 통해 구하였다. 상용 코드를 사용하여 전복 응력 해석 수행시 저장 용기의 강체 운동에 의하여 계산 시간이 길어지는 데, 이런 계산 시간을 줄이기 위해 일차 충돌 직전까지의 모델의 속도와 각속도 계산식을 이론적인 방법으로 구하여 해석 초기 조건으로 사용하는 방법에 대하여 제안하였다.(중략)

A test of the 1/3 scale model was conducted to verify the tip-over analysis of a dry. concrete storage cask under a hypothetical accident condition. The tip-over analysis was executed using the velocity at each point as the initial conditions of the model just before the impact. The initial velocity was determined from the initial angular velocity, which would make the equivalent kinetic energy to the potential energy. To confirm the structural integrity of the canister, the visual testing and the non-detective testings such as Liquid Penetrant testing and Ultrasonic Testing were conducted. The lid of a storage cask was plastically deformed near the impact point. The structural integrity of storage cask was maintained. To verify the tip-over analysis the strains and the accelerations acquired by the tip-over test were compared with those by the analyses. The results of the analysis were larger than the test results about two times.

A wheeled armored vehicle is a military vehicle that has been developed to enhance combat capabilities and mobility for the army. The wheeled armored vehicle has a high center of gravity, and it operates on unpaved and sloped roads. Therefore, this vehicle has a high risk of rollover crashes. To design the interior of the military vehicle, the crew's safety during rollover crashes is an important factor. However, actual vehicle tests for design are extremely expensive. In this paper, nonlinear dynamic analysis is performed to simulate the rollover crashes and the passenger injury is assessed for a wheeled armored vehicle. The scope of this research is the rollover condition, FE modeling of the wheeled armored vehicle and the dummy, arrangement of dummies, assessment of passenger injuries, and simulation model for rollover crashes.

전복은 부착기 유생을 부착 규조파판에 채묘하여 규조류를 주 먹이로 사육하여 각장 1cm 정도의 것을 바다에 방류하여 상품크기의 것을 다시 수확하는 방식으로 양식되어 왔으나, 최근에는 전복양식에 대한 관심이 높아짐에 따라 전복을 육상수조에서 양성하는 곳이 현저히 증가되고 있다. 하지만, 전복을 양성하는 양어가들은 육성용 먹이로 미역, 파래, 다시마와 같은 천연 먹이를 주로 사용하다가 여름에는 건조미역이나 건조다시마를 공급하고 있는 실정이어서 체계적인 양식 발전에 제한적인 요인이 되고 있다. (중략)

This study evaluated the efficacy and the skin safety and stability of a cosmetic that is an applied water extract and fermented hydrolysate of abalone (Haliotis discus hannai Ino), which was produced at the south coast of Korea. In the patch test, purified water, 1,3-butylene glycol and liquid crystal lotion were used as the reference group, and water extract and fermented hydrolysate of abalone and lotion formulation of water extract and fermented hydrolysate of abalone were used as the sample group. The results of patch test showed no irritation on skin among in any of the test groups. Therefore, the water extract and fermented hydrolysate of abalone (Haliotis discus hannai Ino) are safe for human skin.
