암질분류는 구조물의 설계 및 시공에 영향을 미치는 기본요소를 선택하여 현장에서 관찰, 계측한 후 일정기준에 따라 암반을 등급별로 구분하는데 목적이 있다. 이와 같은 암질분류는 댐, 도로, 터널 등의 설계 및 시공의 각 단계를 통하여 경제성과 안정성에 밀접한 상관 관계를 가지며 중대한 영향을 끼치게 된다. 따라서 암질분류기준은 객관적이고 간편하며 모든 암반에 적용이 가능하여야 하고 구조물의 설계 및 시공에 필요한 정보를 제공하여야 한다. (중략)

In the present study, flexible display technology, which has attracted significant attention in recent years, is discussed. The technology has been widely applied to various devices, such as foldable smartphones and rollable TVs. Notably, different flexible display types from LCD to OLED and E-paper have been employed to implement such devices in practice. Among them, the OLED technology has thus far led the flexible display market. In the present study, the concept and current application fields of the technology are analyzed, and further its potential applications are discussed.

VoIP(Voice over Internet Protocol)는 인터넷과 같은 IP 망에서 음성과 영상을 전송하기 위한 기술이며, 차세대 망에서의 음성, 테이터 통신을 위한 기술로 부상되고 있다. 따라서 VoIP 응용은 인터넷 망을 이용하는 다양한 단말기들 사이의 음성 및 영상 통신을 위하여 더욱더 많이 사용되어 질 것으로 예상된다. 본 논문에서는 VoIP 기술을 여러 분야에 적용할 수 있는 응용성과 실제 다자간 음성통신의 구현 방법에 대해서 기술하겠다.

Objectives : The purpose of this study is to consider the definition, history, classification and clinical effect of balneotherapy. Methods : We researched oriental documents and recent sources of balneotherapy. Results and Conclusions : 1. Balneotherapy is medical cure method which uses physical chemistry effects of water. 2. Records of balneotherapy are seen in oriental documents such as Hwangjenaegyeong(黃帝內經), Sinnongbonchogyeong(神農本草經), Jaebyoungwonhuron(諸病源候論), Youmoonsachin(儒門事親), Bonchogangmok(本草綱目) and Donguibogam(東醫寶鑑) etc. 3. Spa can classify eleven types according to ingredient. The types were as following. Simple thermal spirng, Common salt spring, Sodium bicarbonated spring, Sulfate spring, Radioactive spring, Acid spring, Sulfur spring, Carbon dioxide spring, Iron spring, Alum spring & Sulfate-iron spring, Bicarbonatealkaline spring. 4. Physical, chemical and environmental effect of spa therapy have effectiveness on the chronic and we akness disease more than acute disease. And balneotherapy have more effectiveness on digestive disease, pulmonary disease, metabolic disease, circulatory disease, muscle skeletal disease and dermatologic disease than any other diseases.

The ethanolic extract of chestnut (Castanea crenata S. et Z., Fagaceae) inner shell (CISE) and one of its components, ellagic acid (EA), were evaluated for their protective effects against 1, 1-diphenyl-2-picryl hydrazine (DPPH) free radical generation and hydrogen peroxide-induced oxidative DNA damage in a mammalian cell line. CISE and EA were shown to possess the free radical scavenging effect against DPPH radical generation, significantly. They were also found to strongly inhibit hydrogen peroxide-induced DNA damage from Chinese hamster lung (CHL) cell, assessed by single cell gel electrophoresis assay and 8-hydroxy -2'-deoxy guanosine (8-OH-2'dG) assay. Furthermore, topical application of CISE [$12.5\%$(w/w) cream] and ellagic acid [$1.0\%$(w/w) cream] for 14 days potently inhibited malondialdehyde (MDA) formation of mouse dorsal skin (a marker of lipid peroxidation) induced by ultraviolet B exposure. Therefore, CISE and its component, ellagic acid, may be the useful natural antioxidants by scavenging free radicals, inhibition of lipid peroxidation and protecting oxidative DNA damage when topically applied.
