천음속으로 비행하는 공기흡입유도탄의 경우, 비행거리 및 요구기동을 충족시키기 위해서는 추진제트에 의해 변화하는 기체 기미부의 압력항력을 정확히 예측하고 이 항력을 감소시키기 위한 기미부 형상설계는 매우 중요하며 필수적이다. 제트 Plume에 의한 기체 기미부 및 base의 압력분포에 따른 항력해석을 난류모델링을 고려한 수치해석 결과를 제시한다. Jet plume의 크기 및 배기가스 조건에 따른 항력변화, 및 기미부 형상에 따른 항력변화 그리고 천음속 마하수에 따른 결과 등을 제시한다.

Melasma has several well-recognized etiologic factors, but most researches focus on melanogenesis. The purpose of this study is to show improvement of melasma by reducing vascularity distinguished from melanogenesis. We examined 20 Korean women with both melasma and solar lentigo that were visually assessed by a dermatologist. The volunteers applied functional cosmetics for 8 weeks. We analyzed the results obtained using the chromameter, evaluating the skin color of three areas (melasma lesions, solar lentigo lesions, and non-lesional skin) on the face of volunteer. There was a statistically significant improvement in the brightness and redness of melasma lesions compared to those of non-lesional skin after 8 weeks. Also, we observed that the improvements in the brightness of melasma lesions and solar lentigo lesions were similar. However, the redness of melasma lesions improved more than that of solar lentigo lesions with statistical significance after 8 weeks. In this study, we have shown that brightness and redness in melasma lesions can be improved by functional cosmetics. Thus, we suggest redness to be an additional suitable parameter for the evaluation of melasma lesions.

The purpose of this study is to investigate the changes of ginseng properties through bibliographical records. The cultivation of Korean wild simulated ginseng (mountain cultivated ginseng) started from the Goryeo Dynasty around A.D. 1000. Thereafter, from A.D. 1500 to A.D. 1600, ginseng cultivation technology was established in the Joseon Dynasty. At this time, the ginseng was begun to grow in the field near the house, and it is recorded as Gasam (field cultivated ginseng). The Jung-Jo-Sil-Rok (A.D. 1790) states that Gasam cultivation has expanded to the whole country. The properties of ginseng described in almost all oriental medicine books from A.D. 250 to A.D. 1600 were a slightly cold. However, after A.D. 1600, it is said to be slightly warm or warm. Considering from this record, the slightly cold ginseng before A.D. 1600 can be recognized as the properties of wild ginseng or wild simulated ginseng, and the slightly warm ginseng after A.D. 1600 can be recognized as Gasam properties.

The Benangkimi wetland, which serves as a stopover place for migratory birds in the Dadohae Marine National Park in Wando-gun, Jeollanam-do, is a place where various species and a large number of migratory birds are observed. In order to provide an effective and scientific management plan for the habitat environment of migratory birds, we carried out field survey of Benangkimi wetland. The field survey and survey on habitat use of migratory birds were conducted in parallel to obtain the basic data of hydraulics and hydrology. The hydraulic and hydrological survey of Benangkimi wetland was conducted 1-2 times a year during the period of 2015-2016 (two years). It was classified into 4 sectors according to the topography and geology, rainfall, hydraulic characteristics, and wetland conditions. The 3 sectors same as the migratory birds survey sector and the 1 sector as the inflow of the wetland were analyzed. The survey also focused on small migratory birds arriving at Benangkimi wetland during the spring and autumn season. As a result of investigating the population and species in each section, the habitat environment was different according to the water depth, sediment thickness and salinity. Migratory birds prefer hydraulic and hydrological characteristics. This study will be used for the scientific management of Benangkimi wetland, which serves as a stopping point for migratory birds, and it will contribute to basic data of ecology - hydraulics by examining the relationship between habitat environment and hydrological data.

The purpose of this study is to understand the food and nutritional value of based on the oriental Qi-flvor theory and to convergence understanding of dietary effects. In this study, dietary effect of Yulmubokyeoljuk based on oriental theory and analyzed the contents of general composition and minerals. We recognize the value as a food that can be used for therapy of Yulmubokyeoljuk. Phosphorus content was high and high calory foods. In addition, by discharging stagnant water in the spleen, excessive wetness is removed and the function of transportation of the spleen is strengthened. The results of this study suggest that it provided the basis of the characteristics of food and the necessity of convergence approach to dietary efficacy based on the traditional Qi-flvor theory and nutrional composition.
