김현지,이점식,고상훈,이수용,Kim, Hyeon Ji,Lee, Jeom-Sig,Ko, Sanghoon,Lee, Suyong Korean Society of Food Science and Technology 2015 한국식품과학회지 Vol.47 No.6

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.

김현지,정재묵,박종혁,백근욱,허성회,Kim, Hyeon Ji,Jeong, Jae Mook,Park, Jong Hyeok,Baeck, Gun Wook,Huh, Sung-Hoi 한국수산과학회 2017 한국수산과학회지 Vol.50 No.5

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.

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.

Objectives : To assess the effectiveness of Chuna manual therapy in patients with Tourette's syndrome. Methods : We queried nine electronic databases using the keywords “Tourette's Syndrome” and “tuina OR chuna” to identify RCTs that investigated the effectiveness of Chuna manual therapy in patients with Tourette's syndrome. Results : Thirteen RCTs were selected according to the inclusion criteria. A system- atic review showed that Chuna manual therapy can have a curative effect on patients with Tourette's syndrome. Conclusions : In this study, 13 RCTs reported that Chuna manual therapy was effec- tive for Tourette's syndrome. These findings provide a basis for its clinical use. However, all studies involved populations belonging to the same country. Many stud- ies lacked details of the research methodology. Therefore, further studies are re- quired to produce high-quality evidence.

김현지 ( Hyeon Ji Kim ),정재묵 ( Jae Mook Jeong ),예상진 ( Sang Jin Ye ),백근욱 ( Gun Wook Baeck ),허성회 ( Sung Hoi Huh ) 한국어류학회 2016 韓國魚類學會誌 Vol.28 No.1

2011년 6월에서 8월까지 거제 연안에서 RN80으로 채집된 살망둑 (Gymnogobius heptacanthus) 치어 229개체의 소환관 내용물 조성을 조사하였다. 살망둑 치어의 체장은 14~29 mm의 범위를 보였으며, 요각류 (Copepoda)가 가장 우점한 먹이생물이었다. 요각류 다음으로는 만각류 (Cirripedia)의 Cypris 유생이 우점하였으며, 그 외 지각류 (Cladocera), 십각류 (Decapoda) 등도 섭식하였으나 그 양은 많지 않았다. 살망둑 치어의 섭식 전략과 섭식패턴을 알아보기 위하여 도해적방법을 이용한 결과, 요각류 중 긴노요각목 (Calanoida)이 출현빈도와 특정먹이 생물우점도에서 가장 높게 나타나 살망둑 치어는 긴노요각목을 가장 우점적으로 섭식하는 종임을 알 수 있었다. 살망둑 치어는 모든 체장군에서 요각류를 주로 섭식하였으며, 요각류 중 긴노요각목이 가장 우점하였다. The feeding habits of juvenile (14.0~29.0 mm SL) of Gymnogobius heptacanthus were examined based on 229 individuals, that collected from June to August 2011 in the coastal water of Geoje, Korea. G. heptacanthus fed mainly on copepods which constituted 96.74% in IRI. Barnacle larvae were the second largest dietary component. Its diet also included small quantities of tintinnids, cladocerans and decapods. Graphical analysis of the diet composition showed that G. heptacanthus is a specialized predator characterized by strong individual feeding specialization. Especially copepods were heavily selected by of juvenile G. heptacanthus regardless of prey availability.

김현지(Kim, Hyeon Ji),권기한(Kwon, Ki Han) 한국웰니스학회 2021 한국웰니스학회지 Vol.16 No.4

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.
