저서동물은 저서환경특성을 나타내는 중요한 지시자로 알려져 있다. 본 연구에서는 무안만 조 하대의 환경 및 저서동물의 분포특성을 조사하였으며, 수질평가지수(WQI)와 저서생물지수 (AMBI)를 이용하여 저서생태계 건강성을 평가하였다. 현장채집은 2019년 하계 무안만 조하대 의 10개 정점에서 이루어졌다. 무안만 조하대는 상부지역이 하부지역에 비해 세립한 입도특성 을 나타내고 있었으며, 높은 유기물 함량을 보였다. 일부 정점에서 오염지표종인 Musculista senhousia, Theora fragilis and Lumbrineris longifolia과 같은 종들도 우점을 나타내고 있었다. 군집분석결과 무안만 조하대는 상부, 중부, 하부 그룹으로 구분되었으며, 유기물 함량과 저서 건강성 평가지수(WQI 및 AMBI)와의 상관결과와 일치하였다. 본 연구결과, 무안만 조하대의 저서생태계는 양호한 것으로 평가되었다. 하지만 저서동물이 균등하게 분포하지 않고, 기회 종이 출현하고 있어 조하대의 유기물 부하량이 증가하고 있는 것으로 보인다.

The aim of this study is to look at how pepper was used in traditional medicine. In other words, this study aims to take a look at the process by which the medicinal nature & efficacy of pepper in traditional society was perceived and arranged through the aspects of the use of pepper as an exotic crop for treating diseases. This study investigated cases of using pepper for medical treatments by referring to books on traditional medicine in Korea. The old records about pepper are mainly in empirical medical books from the late Chosun dynasty. Nevertheless, the records about pepper tend to decrease in medical text as time goes by. Such a phenomenon can be attributable to the fact that people began to use pepper for daily food life rather than for medicinal purposes. Pepper was used mostly for digestive trouble such as vomiting, diarrhea, and stomachaches, and it was also applied to mental and aching diseases caused by the sound of body fluids remaining in the stomach. In addition, there were many cases where pepper was used externally for surgical disorders. Such symptoms for treatment are linked to, or in a complementary relationship with, research results in modern times. Boiled pepper was generally taken in the traditional herbal decoction method, and in the case of surgical diseases, it was applied externally. The cases of using old pepper, using pepper with seeds or without seeds, and using pepper mixed with sesame oil belong to a sort of herbal medicine processing, which usually aimed at changing the medicinal nature of pepper. In addition, in relation to the eating habits at that time, pepper was used as seasoning and to make red pepper paste with or without vinegar. There are two words used for pepper in the medical textbooks, 苦椒 (gocho) and 烈棗 (yeoljo). These words are translated into Korean as gochu, so we can identify this word as a nickname for pepper.

"Sikui-simgam ("食醫心鑑", Book for Alimentotherapist)" written by Jameun, a doctor of Tang (唐) in the 9th century, propagated alimentotherapy in Korea, China, and Japan for a long time. In this study, Sikui-simgam medical theories were studied and the medicinal ingredients and types of food therapy were analyzed to understand alimentotherapy characteristics. "Sikui-simgam" is the first food therapy formulary diverged from herbal therapy forms. Various ingredients from "Sikui-simgam" show the food culture of the Tang age and report much about cooking and cultural history. Many prescriptions in the books are the origins of present-day food culture; thus, they are important clues to understand the present food culture. This book also describes actual prescriptions in detail. Various types of prescriptions with different ingredients are unique characteristics of food therapy and show the various possibilities for food therapy prescriptions. The food therapy prescriptions of "Sikui-simgam" were designed for medical specialists, as the book contains doses and incompatibilities for food therapy. Such food therapy prescriptions were used to treat diseases, so they were used with strict standards.
