Although an adequete intake of calcium (Ca) is recommended for the treatment and prevention of osteoporosis, the intake of Ca should be restricted because of its low rate of intestinal absorption. The purpose of this experiment was to identity the effect of the combined administration of Aquamin F (AQF) (a calcium agent) and lactic acid bacteria (LAB) on osteoporosis. Thirty ovariectomized (OVX) rats and six control rats were assigned to the following six groups, with six animals per group: sham Ca-deficient diet (Ca-D), OVX, LAB, AQF, and LAB-AQF. During the experiment, the body weight was measured; and after the experiment was completed, the serum biochemical analysis, the alkaline phosphatase, calcium, and inorganic phosphorus leves were measured. The tissue of the femur was stained and then scanned via CT. The body weight of the OVX group increased more significantly than that of the control group. The results of the bone mineral content (BMC), Bone mineral density (BMD), serum biochemical analysis and histological test on the femur epiphysis showed no difference between the OVX group and the LAB group, whereas the results of the AQF group were more significant than those of the OVX group. In particular, the LAB+AQF group showed more significant increases in the aforementioned results than the AQF group. This experiment showed that the combined administration of AQF and LAB in ovariectomized rats more significantly increased bone density than did a single administration of either AQF or LAB.

The present study was conducted to investigate the effects of beverages containing fermented Akebia quinata extracts on alcoholic hangover. For this study, 25 healthy young men were recruited. All participants consumed 100 mL of water (placebo), commercial hangover beverage A or B, fermented A. quinata leaf (AQL) or fruit (AQF) extract before alcohol consumption. After 1 h, all participants consumed a bottle of Soju, Korean distilled liquor (360 mL), containing 20% alcohol. Blood was collected at 0 h, 1 h, 3 h, and 5 h after alcohol consumption. The plasma alanine transaminase (ALT) activity was highest in the placebo group. Compared with the control group, the AQL and AQF groups showed decreased ALT activity at 5 h after alcohol consumption. Plasma ethanol concentration was increased after alcohol intake and peaked at 3 h after alcohol consumption. Compared with the control group, the A group showed a higher plasma ethanol concentration at 1 h (P<0.05). At 3 h after alcohol consumption, the AQF group showed the lowest mean plasma ethanol concentration compared to the other groups; however, there were no statistical differences. After 5 h of alcohol consumption, the AQL and AQF groups showed lower plasma ethanol concentrations compared with the B group. The sensory evaluation score for the fermented A. quinata fruit extract was lower than for the commercial hangover beverages. In conclusion, the present intervention study results suggest that fermented A. quinata extracts alleviate alcoholic hangover and reduce plasma ethanol concentrations.

This paper investigates the characteristics and implementation of associate degree and advanced diploma in Australia, which belong to level 6 in AQF, to gain meaningful implications for engineering associate education in Korea. In Australian Qualification Framework and Engineers Australia's national generic competency standards are regarded as common benchmark for both qualifications. Training packages for advanced diploma were changed according to the subject/and national benchmark. and were developed to meet the needs of technical workers and para-professionals in the engineering field. The author recommends three suggestions from the findings - leadership of ABEEK for making benchmark for associate degree program in engineering in Korea, in which competency-based curriculum is currently being adopted by policy. development of outcomes descriptor of qualification and educational responsibilities.

으름열매는 폴리페놀과 사포닌과 같은 페놀성 물질을 많이 함유하고 있다. 본 연구는 세포실험을 통해 으름열매 추출물의 항산화활성을 확인하고, 피부에 적용하였을 때 수분과 유분, 멜라닌과 홍반변화의 효과를 측정하였다. 항산화 효과 측정결과, 농도 의존적으로 폴리페놀, 플라보노이드, DPPH소거능이 상승한 것으로 확인되었고, 으름열매 추출물 크림을 사용하였을 때 수분함량 변화, 유분함량 변화, 멜라닌지수, 홍반지수의 감소가 통계적으로 유의미한 변화를 보여 으름열매 추출물 함유 화장품이 피부개선을 위한 기능성화장품으로서 활용 가능성을 확인할 수 있었다. 따라서 본 연구에서는 으름열매 추출물은 독성을 나타내지 않으면서도 피부보습, 피부개선효과를 가진 천연 및 기능성화장품 소재로서 활용 가능성이 있다고 사료된다.
