According to Li Sizhen, Drinking a little makes heart health, spirit active and let be relieved of fatique. Also it hastens gastroenteric digestion. In result, the appetite is stimulated. So Good-wine is useful for well-being necessary to treat a disease much more. However if drink to excess, it will cause mental disorder, exhansted blood, Impairment of stomach. As a consequence of that. Essence of life is exhausted too. So phlegm forms, Fire is more active easily. [In compendium of Materica Medica], 120 classes of counteracting Alcohol Drugs find room in it. Like this, an abundance of data and investigation about Counteracting Alcohol Drugs provides to us a large of Medical materials, and is a guide in Developing and Using the herbal resources. [Lei Gong's Nature of drugs in Songs] says 'Wine have a effect that get out Extravasated Qi and get rid of Pathogen, Abdominal mass with distension and pain.< As it says, ancient doctors displayed remedical Value that promote Qi and Blood circulation as a power of wine. But others says, 'To drink a wine as a drinking water makes us so intemperate, lets us be so being unreasonable easily as to drink hard and hurt our body. (1)Drink with nutritive appetizer. (2) Drink with sitting down. (3)Drink slowly. (4)Do not drink a differ on wine that is not true who makes. (5)Go easy on the alcohol. If drink with this position. Never drink hard for hurting body. Therefore, Cao Tingdong lived in the qing dynasty says "A preventing as a medicine is not so good as a preventing as a temperate living and meal."

One-dimensional modeling of $CH_4$/air premixed flame was conducted to validate the heat loss model and investigate NOx formation characteristics in the postflame region. The predicted temperature and NO concentration were compared to experimental data and previous heat loss model results using a constant gradient of temperature (100 K/cm). The following conclusions were drawn. In the heat loss model using steady-state heat transfer equation, the numerical results using the effective heat loss coefficient ($h_{eff}$) of $1.0\;W/m^2K$ were in very good agreement with the experiments in terms of temperature and NO concentration. On the other hand, the calculated values using the constant gradient of temperature (100 K/cm) were lower than that in the experiments. Although the effects of heat loss suppress NO production near the flame region, a significant difference in NO concentration was not found compared to that under adiabatic conditions. In the postflame region, however, there were considerable differences in NO emission index as well as the contribution of NO formation mechanisms. In particular, in the range of ${\phi}\;{\geq}\;0.8$, the prompt NO mechanism plays an important role in the NO reduction under the adiabatic condition. On the other hand, the mechanism contributes to the NO production under the heat loss conditions.

This report describes the studies as follows through the research into the data of Fructus Forsythiae main blended prescriptions from Dongeuybogam. Through investigation on prescriptions from Dongeuybogam with Fructus Forsythiae as an ingredient, the following conclusions were reached. 1. All kinds of infection in a boil and the malignant tumor recorded the largest number of clinical frequency of the prescriptions in therapeutic use when Fructus Forsythiae was taken as a principle medicine. 2. The prescriptions are compounded with Fructus Forsythiae as a principle medicine can apply to eye disease, nose and ear disease, throat disease, trauma, the malignant tumor, skin disease, dental disease and heat pathogenic disease. 3. Various pathogenic factors such as wind-heat, heat, fire, wind, qi, poison, cold are put to practical use. 4. The dosage of Fructus Forsythiae is 2bun(about 0.75 gram) to 3jeon(about 11.25 gram), however 1joen(about 3.75 gram) has been taken the most for clinical application. 5. With examination the formulae of presciptions containing Fructus Forsythiae, I found the basic prescriptions as well as the medicines are in conjunction with Fructus Forsythiae and the theoretic grounds of formula in combining Fructus Forsythiae as a group of medicine for prescription through this research.

Even though continuous management and supervision of reinforcement of policies to safeguard accidents at workplace and work sites were implemented. Accident prevention activities such as inspection and diagnosis are urgently required to induce a preliminary investigation to identify the risk factors for each type of work, before the work task to eliminate risks at the worksites. Since safety inspections at work sites were generally conducted through visual inspections, the results of safety inspections may vary depending on the findings and proficiency of the safety officers. The results of those inspections may have loopholes to prevent potential accidents at work. Therefore, the purpose of this study was to develop a risk identification checklist that can effectively perform safety inspections to prevent accidents at work sites. This study initially analyzed the previously developed accident checklist to identify current complications and issues in safety checklists. Based on the findings of major industrial accidents over the past three years, the relationship between accident, workplace, and work type were analyzed refereeing the safety inspection standards. A risk recognition-checklist was developed to provide basic data on identifying risk factors, and inspection guidance at work sites. To prepare for potential accidents by identifying and taking countermeasures to mitigate the high risk and serious accidents at sites by the guidelines of the checklist. The developed inspection checklist has been practically used by experts at work sites to perform safety inspections, and it has been verified its suitability, and feasibility, to prevent or mitigate workplace accidents, including securing the safety and health of field workers. The role of the developed safety checklist has been considered effective at worksites.

The primary objective of this study is to investigate the production and performance characteristics of structural concrete incorporating varying proportions (0%, 25%, and 50% by volume) of pumice stone, as well as aluminum lathe as an additive at 0%, 1%, 2%, and 3%, under fire conditions. The experiment will be conducted over a period of up to 1 hour, at temperatures ranging from 24℃, 200℃, 400℃ and 600℃. For the purpose of this, a total of twelve test samples were manufactured, and then tests of compressive strength (CS), splitting tensile strength (STS), and flexural strength (FS) were performed on these samples.Next, a comparison was made between the obtained values and the influence of temperature. To achieve this objective, the manufactured samples were placed at temperatures of 200℃, 400℃, and 600℃ for a duration of 1 hour, and were subjected to the influence of temperature.These values at 24 ℃ were then contrasted with the CS results obtained from test samples that were subjected to the temperature effect for an hour at 200 ℃, 400 ℃, and 600 ℃. A comprehensive analysis of the test outcomes reveals that the incorporation of aluminum lathe wastes into a mixture results in a significant reduction in the compressive strength of the concrete. As a result of this adjustment, the CS values dropped by 32.93%, 45.70%, and 52.07%, respectively. Furthermore, It was shown that testing the ratios of pumice stone alone resulted in a decrease in CS outcomes. Additionally, it was found that the presence of higher temperatures is clearly the primary factor contributing to the decrease in the strength of concrete. Due to elevated temperatures, the CS values decreased by 19.88%, 28.27%, and 38.61% respectively.After this investigation, an equation that explains the connection between CS and STS was provided through the utilization of the data of the experiments that were carried out.
