Purpose: To provide basic informations for guidelines of Ginseng usage during lactation. Method: Based on a regulation of scope and preparation of herbal prescriptions by Ministry of health and welfare of Korea, we selected the formulae for postpartum care and disease in 7 Korean Medical Classics. And we searched the number of formulae including Ginseng, dosage and indications of Ginseng in formulae in those books. Results: The range of Ginseng dosage during lactation from medical classics is 1.5-18.75g/day for medical purposes. Indications of Ginseng are lethargy, excessive bleeding, asthma, fever, cold, pain, dizziness, mental disorder, spasm, digestive problem, constipation, diarrhea, urinary incontinence, edema, breast engorgement, lack of breastmilk, breast ulcer, etc. But Ginseng had not been used in the case of stroke, epistaxis, beginning of mastitis, tumor of lower abdomen. Conclusions: Ginseng should be recommended less than 1.5g/d as a nutritional supplement. If breastfeeding woman wants to take Ginseng as a medication or as a tonic, she should consult with a official specialist about proper prescription and dosage instead of risky random medication.

Objectives: The impact of climate change on the health has been of increasing concern due to a recent temperature increase and weather abnormality, and the research results of the impact varied depending on regions. We synthesized risk estimates of the overall health effects of low and high temperature taking account of the heterogeneity. Methods: A comprehensive literature search was conducted using PUBMED to identify journal articles of low and/or high temperature effects on mortality. The search was limited to the English language and epidemiological studies using time-series analysis and/or case-crossover design. Random-effect models in meta analysis were used to estimate the percent increase in mortality with $1^{\circ}C$ temperature decrease or increase with 95% confidence intervals (CI) in cold or hot days. Results: Twenty three studies were presented in two tables: 1) low temperature effects; 2) high temperature effects on mortality. The combined effects of low and high temperatures on total mortality were 2% (95% CI, 1-4%) per $1^{\circ}C$ decrease and 4% (95% CI, 2-5%) per $1^{\circ}C$ increase of temperature, respectively. Conclusions: This meta analysis found that both low and high temperatures affected mortality, and the magnitude of high temperature appeared to be stronger than that of low temperature.

The purpose of this study is to classify achromatic color images adopted by contemporary fashion design in order to analyze the links between achromatic color images and fashion images. To this end, the study on the images of achromatic colors of White, grey, and black was conducted by reviewing related documents. In order to analyze the image factors affecting contemporary fashion design, the documents related to fashion history were consulted and in the case of fashion design factors and images, fashion looks using achromatic color as a main theme were referred. The results of this study are as follows : 1. An achromatic color is cold, calm and plain as well as modern. At the same time, it is abstinent and solemn so the color has been mainly used as religious garment. 2. An achromatic color used in apparels has been influenced by the developments of culture, art, society, ideology, politics, economy, science and technology. Black dress was introduced by Art Deco colors, little black dress by feminism, white by the popularity of sports, black becomes more popular by nihilistic beat and punk generations, moon look and cyber punk look were introduced for the advancement of science. Other apparel looks using the color are modern look, feminine look, futuristic look, mannish look, sportive look, and avant-garde look.

Decadence is a phenomenon that people express fear from their inside, so unsound aspects appear in the social culture when the existing society is about to be collapsed. This study covered the cultural and aesthetic meaning and the role of decadence by examining the concept and phenomenon of it and analyzing the real case of expression appeared in the modern fashion. Characteristics of decadent phenomenon were divided into sexual corruption, ideality, cynicism and extreme technique, and decadent expression appeared in the fashion images was examined based on the divided phenomenon. Main results are as fellows. People bring the incidents that animals go through into relief, sticking to animal instinct when the society is on the decline. At that time, sexual decadence becomes remarkable, so voyeurism by exposure in their dress is deepen, revealing abnormal sexual propensity with bisexual tendency and sexual perversion. The real facts and appearance of people are revealed by transforming and distorting bodies for the fear of humans inside suppressed in the fin-de-siecle mood. The sense of alienation and helplessness of people anxious about the future is developed to cynicism expressing the uncertain emotion in their dress, and the formative methods of dismantlement. destruction and abrasion appear to form sickly images in the gloomy and cold mood. The intention of affirmative decadence is realized by mixing heterogeneous styles and producing new things. Extreme decorative technique and gorgeousness are even mysterious and show the highest refinement.

The effect of thermal stratification on the stratified flow past a circular cylinder was examined in a wind tunnel. Turbulent intensities, the rms values of temperature and turbulent convective heat flux as well as the velocity and temperature profiles in the cylinder wake with a strong thermal gradient of $200^{\circ}C/m$ were measured by using a hot-wire and cold-wire combination probe. It is found that the temperature field affects as an active contaminant, so that the vertical growth of vortical structure is suppressed and the strouhal number decreases with increasing the extent of stratification. And also, the wake structure can not sustain their symmetricity about the wake centerline and vertical turbulent motion dissipates faster than that of the neutral case when such a strong thermal gradient is superimposed. It is evident that the turbulent mixing in the upper half section is stronger than that of the lower of the wake in a stably stratified flow because the turbulent intensities and convective heat flux in the upper half section are larger than those of the lower half of the wake.

Computations were performed to investigate the effects of air staging on combustion in three stage heavy-oil fired combustion burner. The burner was designed for 3 MW. Different amounts of air are introduced into each 3 three stages by means of each dampers. The goal of the study is to understand combustion phenomena according to each air stage mass ratios through CFD. Air flow rates at three inlets are adjusted by dampers inside a burner. Here, injection conditions of liquid fuel are kept constant throughout all simulations. This assumption is made in order to limit the complexity of oil combustion though it may cause some disagreement. In case of cold flows, only longitudinal velocities arc considered, On the other hand, flow, temperature and NOx generations are taken into account for reactive flows. Simple parametric study was conducted by setting 1'st air stage mass ratio as a parameter. And an optimal operation condition was found. The computational study is based on k-e model, P-1 radiation model(WSGGM) and PDF, and is implemented on a commercial code, FLUENT.
