Objectives : This study was performed to review the overseas clinical research trends on the effect of On cheong eum on skin disease. Methods : We searched articles in the Pubmed using keywords "On cheong eum", "On sei in", "Wen qing yin", "Jie du si wu tang" and "Jie du si wu decoction". We also searched in the China National Knowledge Infrastructure(CNKI) using key words "温清饮" and "解毒四物汤", We selected 5 studies after excluding non-clinical or unrelated studies. Results : One pre-post comparison study and four controlled clinical trials were performed. On cheong eum and modified On cheong eum were used for the treatment of skin disease-recurrent aphthous ulcer, psoriasis vulgaris, neurodermatitis, and skin pruritus. All of the studies showed positive results, and they reported that the treatment group had higher effective rate than control group. However, the quality of these clinical studies were not evaluated. Conclusions : According to this study, On cheong eum would be an effective and safe intervention in skin disease. Therefore, based on this study, more clinical research using On cheong eum should be performed in Korean medicine in the near future.

'Cheong Wi Dan (淸胃丹)' is a Chinese patent preparation which has been used for various diseases in Korea. This preparation consists of 19 powder crude drugs. Cheong Wi Dan is used for catarrh of the gastrointestines, indigestion, a pain in the chest and nausea. The microscopic method is ve교 useful to identify individual gradients in powdery mixture because it requires only a small amount of specimens. In this study, it is demonstrated that the microscopic method is very useful for the identification of 19 crude drug ingredients included in Cheong Wi Dan.

Korea Ginseng Corporation is a global ginseng company, owning one of the most leading brands in Korea, CheongKwanJang. Although Korea Ginseng Corporation was an undoubted market leader in the red ginseng market, it faced a new challenge in 2012 due to the changes in market environment. In order to keep its market leadership in a saturated and competitive market, the company decided to extend its product lines alongside the launches of new brands. In this article, the authors demonstrate the development process of the company's brand portfolio strategy to reveal how the company turned CheongKwanJang into a mega-brand. Also, this paper explores the impact of CheongKwanJang's reputation on new brands, thereby illustrating how the company successfully managed to introduce new products outside of the red ginseng category, ranging from organic food to a pet food market.

코로나19 팬데믹 이후 배달 앱 사용량이 증가에 따라 배달 오토바이 수가 급증하면서 이와 관련 사고 또한 급격히 증가하는 추세를 보이고 있다. 특히 청각 장애인들은 도로에서 이러한 종류의 사고 위험에 더욱 노출되어 있으며, 이 문제를 해결하기 위해 구글 앱 인벤터를 사용하여 도로에서 오토바이 소리를 인식하는 인공지능 학습 모델을 개발하였다. 개발된 어플리케이션은 도로에서 오토바이 소리를 감지하고 사용자에게 진동과 사진으로 알림을 보냄으로써 사고를 예방에 기여할 수 있다.

Daegeum is the only Korean musical instrument that uses cheong The characteristics of cheong have to be considered first for the sound synthesis of daegeum. This study analyzes the changes of partials in accordance with the vibration of cheong. It shows that amplitudes differ at the partials after about the seventh partial. The study also found that, unlike the case of partials, the vibration of cheong has nothing to do with noise. We expect that this study results can be applied to the sound synthesis of daegeum.

This study was carried out to analyze the nutritional composition, bioactive compound and antioxidant activity in fresh sprout of 3 new Kalopanax septemlobus cultivars. Cheong-San, Cheong-Song and Cheong Sun 1 had largest carbohydrate (52.90, 53.12, 55.28%), crude protein (34.23, 31.33, 33.58%) in the proximate composition and had largest K (2.29, 2.22, 2.23%) followed by Ca (0.44, 0.34, 0.37%), Mg (0.24, 0.19, 0.19%) in the mineral contents. Three new cultivars contained a total of 26, 25 and 28 different kinds of amino acids, respectively and the number of essential amino acid is 6, 6 and 7 species, respectively. Also, Cheong-San had higher total polyphenol contents and Cheong-Song had higher total flavonoid contents. DPPH free radical scavenging activity of 70% ethanol, water extracts of Cheong-San and Cheong-Song is higher than others at 100 ppm. In the ABTS radical cation decolorization activity, 70% ethanol extract of Cheong Sun 1, water extract of Cheong-San and Cheong-Song are higher activity than others and all samples have more than 85% ABTS racial cation decolorization activity at 500 ppm. Our results suggest that new K. septemlobus cultivars possess good antioxidant capacities with a high nutritional value and might have potential applications in the food and medical industries.

Omija-cheong, concentrated extracts from sugar-treated Omija fruit (Schisandra chinensis Baillon), is produced by traditional manner in Korea. The quality characteristics of Omija-cheong processed at low temperature with a pilot-scale were investigated to optimize the incubation time. With increasing incubation time in processing Omija-cheong, the pH level of Omija-cheong remained constant, while titratable acidity and organic acids increased. Fresh Omija fruits contained citric, malic and succinic acids, most of which were extracted into concentrated extracts after 37 days of incubation and reached to the stable concentration after 47 days of incubation. Titratable acidity in Omija-cheong gradually increased from 1.18% to 2.71%, and also was correlated with total concentration of organic acids. About 80% of supplemented sucrose for manufacturing Omija-cheong was converted into glucose and fructose until 68 days of incubation, and the composition of free sugars was maintained to be stable up to 138 days of incubation. The contents of total flavonoids and phenolic compounds in Omija-cheong were 24.1 mg-GAE/L and 1,635 mg-QE/L at 57 days of incubation, which were more than 9 and 5 times higher than those in Omija fruits, respectively. From the quality characteristics in processing Omija-cheong by low-temperature incubation, more than 60 days of incubation is required for the constant quality and value-added beverage.

Intussusception in adult is a rare disease and laparotomy is usually considered because of the probability of malignancy. Especially with obstruction symptom or sign, it might be needed emergency operation. This case was a simultaneous development of small bowel intussusception and acute hepatitis A. The patient had abdominal pain and vomiting. Intitial laboratory examination with elevated aminotransferase revealed that the diagnosis was acute hepatitis. As managing acute hepatitis, the abdominal pain was not improved and the patient had tenderness on periumbilical area on physical examination. A jejunal intussusception with a lead point was proved on the abdominal computed tomography scan. Fortunately, symptom of intussusception was relieved while nulli per os (NPO) and intravenous hydration. After recovery of acute hepatitis, laparotomy was done. The lead point was $2.5{\times}3.0cm$ sized hamartoma. This was the case that the symptom of intussusception was confused with that of acute hepatitis.
