조선 후기인 18세기 전후에는 각종 민화(Min-Wha)들이 민중들의 생활 속에서 중요한 의미를 지니게 되면서 소재나 기법에서 독특하고 다양한 작품들이 등장하게 된다. 이러한 민화 가운데에서 특이한 표현 양식 중 하나로 혁화(Hyuk-Wha)를 들 수 있다. 혁화는 그 기법으로 볼 때, 서예의 표현 양식의 하나로 분류되는 비백서에서 유래를 찾을 수 있는데, 버드나무 껍질이나 갈대류의 줄기를 바르게 펴서 붓 대용품으로 써서 작업한 비백서의 다소 거친 질감과는 시각적으로 큰 차이를 보이고 있다. 또한, 혁화의 발전 과정은 민화 전체의 발전 과정과 밀접한 관계를 가지고 있다. 그 중에서도 도교적인 길상문자 문자도 및 유교적인 효제문자도와 깊은 연관성을 가지고 있으며, 다른 형식의 창의적이고 차별화 된 문자도 형식으로 발전하기도 한다. 그런 까닭에, 문자가 내포하고 있는 의미와 한자의 뛰어난 조자력을 상징적으로 조형화 한 혁화는 오늘날 그래픽 분야의 워드 마크(Word Mark)나 브랜드 로고타입(Brand Logotype) 등에 응용되는 픽토그래피(pictography)와도 연관이 있다고 할 수 있다. 과거 민중의 집안을 꾸미고 장식하는 용도로 성행했던 혁화는, 오늘날 다양한 장식용품의 등장과 현대화된 주택의 발달로 그 용도는 거의 소멸되었다 해도 과언은 아니다. 그동안 민화의 한 부분으로 자리를 잡고 서예 및 문자도 와 더불어 발전해 온 혁화가 서구에서 활발하게 활용되고 있는 현시점에 비추어 볼 때, 그에 대한 재조명이 필요하다 할 것이다.

A convenient high performance liquid chromatographic method was established for the quantitative determination and content uniformity test of aclatonium napadisilate preparation. This method was more simple to make the sample solution for injection, and easy to determine the content in the preparation. Aclatonium napadisilate was chromatographed using a $Lichrosorb-NH_2$ column $(4mm\;{\times}\;25\;cm$, and acetonitrile-water mixture (83:17) as an eluent at a flow rate of 1.8 ml/min. RI-detector response was linear over a range of $0.5{\sim}2.0%$ aclatonium napadisilate under above conditions. Reproducibility studies gave relative standard deviation of 1.29%.

A great deal of attention has been paid to entrepreneurship and social enterprises that help improve societies' ability to solve social problems and develop new ways of thinking (Drucker 1995). Dong Wha Pharm, founded in 1897, was the first social enterprise in South Korea. The purpose of this study is to provide meaningful insights into the theoretical development of social entrepreneurship and how to achieve social innovation by fostering social entrepreneurship. Drawing on the five critical elements of social entrepreneurship developed by Dees (1998), we explore social entrepreneurship by investigating the first Korean social entrepreneur, Kang Min, the founder of Dong Wha, a 125-year-old company in South Korea. The findings offer meaningful and valuable insights to the literature on social entrepreneurship and to current and potential social entrepreneurs wanting to find new ways to achieve social improvement and move society forward.

Buccal absorption test of omeprazole in human was performed to determine the permeability of the drug molecule through oral mucous membrane. Oral mucosal adhesive tablets of omeprazole were prepared by compressing the omeprazole with a mixture of sodium alginate and hydroxypropylmethyl cellulose (HPMC) as bioadhesive polymers, magnesium oxide (MgO) as a stabilizer and sodium carboxymethyl cellulose (Na CMC) or cros-carmellose sodium (Ac-Di-Sol) as disintegrants. The bioadhesive force, stability in saliva and release characteristics of the tablets were evaluated. Omeprazole was absorbed about 23% in 15 min through human buccal mucous membrane. Furthermore, omeprazole was stable in saliva for more than 8 hrs when MgO was added to the tablet as the amount of 2.5 fold of omeprazole. The release rate of omeprazole was increased with increasing the amount of sodium alginate in the tablet. From these results, it is suggested that tablets composed of [omeprazole/HPMC/sodium alginate/MgO/Ac-Di-Sol and/or Na CMC (20/6/24/50/10) (mg/tablet)] are potential candidate for buccal drug delivery system.

Effects of Ssang Wha Tang (SWT), a blended Chinese traditional medicine, on the pharmacokinetics of sulfobromophthalein (BSP) were studied in the rats. BSP was administered via portal vein to the control and the SWT-treated rats. The in vitro distribution of BSP to blood cells and the hemato-physiological conditions, liver weight, GOT. GPT activity were also examined. The systemic clearance $(CL_s)$ of BSP was increased with the administration of SWT, but no significant differences were observed in the liver weight and in vitro distribution of BSP to blood cells. These results suggest that the intrinsic clearance of free BSP of the liver is increased with the administration of SWT in the rats.

In this paper, the confirmation method of target detection for the vehicle mounted metal detector (MD) has been described. The vehicle mounted MD with the arrayed 6 coils to detect the width of 2.4 m was demonstrated. It is important and necessary to inform the location of the objects detected by the MD. The confirmation method of target detection was verified by using the MD GUI and the analysis of the receive signal processing. The receive signal processing is performed by comparing the threshold and the difference of the signal calibrated at initial location and the signal detected at present location.
