The feeding habits of post-larval Yatabe blenny Parablennius yatabei (2.0-9.8 mm SL) were examined on the basis of 158 individuals collected from June to October in the coastal waters of eastern Jinhae Bay, South Korea. Based on the index of relative importance (IRI), post-larval P. yatabei fed 94.4% on copepods and 5.6% on tintinnids. The preference of post-larval P. yatabei for copepods to other prey items results from ontogenetic changes. The dietary percentage of copepods increased as fish size increased and tintinnids became less important. The feeding rate of post-larval P. yatabei was consistent at all times of day.

The in-vitro starch digestibility of white and brown rice flours was continuously characterized from a rheological point of view. Specifically, the in-vitro viscosities of the rice digesta samples were monitored under simulated oral, gastric, and intestinal conditions. A trend of decreasing viscosities in all the digesta samples was observed during the in-vitro digestion. After cooking, the brown rice sample exhibited lower viscosity than that of the white rice flour due to the presence of more non-starch components. A similar tendency was observed during the simulated oral and gastric digestions. However, the viscosity crossover between the white and brown rice samples was observed during intestinal digestion. In addition, the amount of glucose released from the brown rice flour was significantly lower than that from the white rice flour. Thus, the slower rate of starch hydrolysis in the brown rice flour could be related to its in-vitro rheological behaviors.

This paper proposes the GPS sensor-based steering angle control algorithm for autonomous driving. The proposed method obtains The desired angle for the steering angle of the servo motor, which is acquired by using the GPS data. This angle is used as the desired goal of the PD controller for minimizing the error between the desired angle and the steering angle. Finally, the PWM signal obtained from the PD controller is directly applied to the servo motor. To demonstrate the validity of the proposed method, this study implements the experimentations for the waypoint based autonomous driving.

본 연구는 코로나바이러스 감염증으로 인해 생긴 30~40대 성인남성의 복부비만을 비침습적 캐비테이션 관리를 통해 개선된 효과를 비교하기 위하여 연구를 시행하였다. 이를 위해 서울 강남구에 소재한 개인 피부관리실에서 체질량지수(Body Mass Index, BMI) 0.90이상 넘는 대상자 20명 중 설문지를 통해 코로나바이러스 감염증 이후 활동량이 감소한 복부비만 중년남성 16명을 선정하였다. 음압을 이용하여 비만세포를 사멸시키는 비침습적 캐비테이션 관리로 복부 비만 관리 효과를 알아보기 위해 4주 동안 주 2회, 10명에 참가자들의 복부에 총 8회 진행하였다. 앞선 선행논문과는 다르게 지방분해에 탁월한 캐비테이션 장비를 상복부, 중복부, 하복부, WHR, 체지방량, 체중, 체지방률에 횟수는 줄이고 시간을 늘려 30분간 진행하였다. 비침습적 캐비테이션이 30-40대 중년남성 복부 비만에 대한 효과는 상복부 둘레 (F=13.075, p<,001) 허리둘레(F=21.298, p<,001) WHR(F=4.132, p<,01) 으로 유의하다. 체지방량(F=3.817, p>.01,) 체지방률(F=3.215, p>.01,)로 유의한 차이가 없다. 무처치군 6명은 오히려 체중, 체지방량, 체지방률이 증가하였고 허리둘레, WHR은 통계적으로 유의한 차이가 없었다. 이는 비침습적 캐비테이션을 통해 코로나바이러스 감염증 시대에 수술 없이 성인남성의 상복부와, 허리둘레, WHR 감소에 더 큰 효과가 있음을 입증한다. 앞으로 비침습적 캐비테이션을 통한 중년남성의 복부비만 관리로 예방에 관한 후속연구가 진행되길 바라며, 본 연구가 상대적으로 여성보다 미흡한 중년남성의 복부비만 관리에 발전이 되는 기초가 될 것으로 사료 된다. This study was conducted to compare the improved effects of abdominal obesity in adult men in their 30s to 40s caused by the COVID-19 pandemic through non-invasive cavitation management. To this end, 16 middle-aged men with abdominal obesity, whose activity decreased after the pandemic, were selected through a questionnaire among 20 subjects with a body mass index (BMI) of 0.90 or higher in a personal skin care room located in Gangnam-gu, Seoul. In order to find out the effect of abdominal obesity management through non-invasive cavitation management that kills obese cells using negative pressure, it was conducted twice a week for 4 weeks and a total of 8 times in the abdomen of 10 participants. Unlike previous papers, cavitation equipment excellent for fat decomposition was conducted for 30 minutes by reducing the number of times and increasing the number of times in the upper abdomen, overlapping, lower abdomen, WHR, body fat mass, weight, and body fat percentage. The effect of non-invasive cavitation on abdominal obesity in middle-aged men in their 30s and 40s is significant as the upper abdomen circumference (F=13.075, p<,001) waist circumference (F=21.298, p<,001) WHR (F=4.132, p<,01). Body fat mass (F=3.817, p>).01) Body fat percentage (F=3.215, p>). There is no significant difference as 01,). The six patients in the untreated group rather increased weight, body fat mass, and body fat percentage, and there was no statistically significant difference in waist circumference and WHR. This proves that non-invasive cavitation has a greater effect on reducing the upper abdomen, waist circumference, and WHR of adult men without surgery in the era of coronavirus infection. We hope that follow-up studies on prevention by managing abdominal obesity in middle-aged men through non-invasive cavitation will be conducted in the future, and this study is expected to serve as the basis for developing abdominal obesity management in middle-aged men, which is relatively insufficient for women.

Despite the prominent advantage of natural dyes, It is difficult to keep or mass produce natural dyes. Natural dyes have limited output compared to chemical dyes. Color cosmetics containing natural dyes is more desirable for consumers preferring naturalistic and environment-friendly products than color cosmetics containing artificial dye. in this study, we assessed anti-oxidation potential, Anti-microbial activity of Curcuma longa L. and made color cosmtics containing Curcuma longa L. Then we evaluated safety and effectiveness to compare with color cosmetics containing artificial dye on the market. The results are as follows. The polyphenol content of 1% Curcuma longa L. were 3.99±1.53mg/g. The flavonoid contentof 1% Curcuma longa L. were 2.12±1.20mg/g. As Anti-microbial activity test results, the clear zone against Staplylococcus aureus was 7mm. The color value of the Curcuma longa L. product are L* 51.44, a* 20.02, b* 55.29 and control product are L* 81.36, a* 19.46, b* 75.21. Seen form H/V/C values, color properties of Curcuma longa L. products were darker and had lower saturation than the control product. Based on these findings, we thought that suggest a possibility in future for development of the color cosmetic containing natural pigment.
