Objectives : In this paper, lung atrophy syndrome[肺痿] in 『Huangdineijin(黃帝內經)』 and 『Jinguiyaolue(金匱要略)』 were compared, followed by examining its relation with upper wasting thirst[上消]. Also, ways in which psychological factors that contribute to lung atrophy syndrome could cause upper wasting thirst were studied. Methods : Verses from 『金匱要略·肺痿肺癰咳嗽上氣病脈證治』 and 『素問·痿論』 were analyzed based on various annotators's opinions to determine the cause and mechanism of lung atrophy syndrome and its relationship with upper wasting thirst. Results : In 『Jinguiyaolue(金匱要略)』, lung atrophy syndrome is described as the heat of the upper body entering the lungs to dry it out. The description in 『Suwen(素問)』 differs in that it accompanies atrophy symptoms, but the mechanism is the same. Lung atrophy syndrome in 『Jinguiyaolue』 could come from wasting thirst, while wasting thirst can be accompanied in deficiency caused by chronic lung atrophy syndrome. Heat in the lungs is caused by psychological factors where the person has lost its subject of possession or was unable to attain what was desired. When expanded to include heart atrophy syndrome[心痿] and lung atrophy syndrome[肝痿], the reason for upper wasting thirst could include immense sadness or excessive indulgence in pleasure due to unmet desires. Conclusions : Although diabetes and wasting thirst are not identical, application of wasting thirst pattern differentiation to diabetes treatment and management could lead to tailored treatment of each patient. Moreover, the five zhang pattern differentiation from the 『Suwen(素問)』 could increase treatment efficacy when applied to conditions caused by stress and emotional disorder, which are increasingly playing larger roles in causing wasting thirst, or diabetes.

Objective: The purpose of this study is to examine the characteristics and the improvement in the symptoms of the patients who showed improvement after the administration of Yeoldahanso-tang and Cheongpyesagan-tang. Methods: The patients whose Sasang Constitution were examined by an expert at six Oriental medical hospitals and three regional Oriental-medicine clinics, 89 showed a predetermined symptom improvement when Yeoldahanso-tang and Cheongpysagan-tang were administered to them from November 2007 to July 2008. The traits of the patients and the effects of their treatment were examined. Results and Conclusions: 1. There were about as many male patients as there were female patients, but 21.3% of the patients who were female and who were in their 40's showed the most improvement, which makes them the biggest category in this study. 2. The main syndromes in which the patients showed improvement were hemi-paralysis, vertigo, and headache, and the ordinary symptoms in which the patients showed improvement were diarrhea, fatigue, and dry mouth. 3. The average food intake of the patients was highest and their feces had intermediate hardness (semi-soft). 4. The amount of the patients' sweat was either high(38.2%) or appropriate(38.2%) and they showed a dislike of heat over coldness. 5. Among the diseases that the patients previously had, high blood pressure. The above results show that Yeoldahanso-tang and Cheongpyesagan-tang can be considered beneficial to females in their 40's and to stroke patients whose food intake is normal, whose sweat level is either copious or appropriate, who dislike heat and who are suffering from high blood pressure.

In this study, experiments were conducted to investigate the correspondence between the output voltage of the photoelectric sensor and the frost height under heating and defrosting capacity test condition (dry bulb temperature $2^{\circ}C$, wet bulb temperature $1^{\circ}C$) described at KS C 9306, where a real heat exchanger was used as a test rig instead of a large-scale model. A digital microscope and a photoelectric sensor unit consisting of an emitter and a transistor (receiver) were installed in the front of it. A linear correlation is proposed to predict the frost height based on 150 experimental data, approximately 54% of the measured data are consistent with the predicted frost heights within a relative deviation of ${\pm}10%$, it yields good agreement with 90% of the measured data when the frost height larger than 0.3mm with in a relative deviation of ${\pm}10%$. Compared with Xiao's correlation, the slope namely, the change of frost height in accordance with the change of output voltage is consistent within the error of 2.3%. But vertical intercept shows big difference with Xiao's correlation, because it was developed with a large scale model instead of a real heat exchanger.

The high speed in the wire-drawing process to meet the demands for the increased productivity has a great effect on the heat generated due to plastic deformation and friction between the wire and the drawing dies. During the high carbon steel wire drawing process, the temperature rise gives a great influence to the fracture of wire. In this paper, to control the temperature rise in the wire after the deformation through the drawing die, the calculation method of the wire temperature, which includes the temperature rise in the deformation zone as well as the temperature drop in the block considering the heat transfer among the wire, cooling water and surrounding air, is proposed. These calculated results of the wire temperature at the inlet and exit of the drawing die at each pass are compared with the measured wire temperatures and verified its efficiency. So, using the program to predict the wire temperature, the isothermal pass schedule program was developed. By applying this isothermal pass schedule program to the conventional process condition, a new isothermal pass schedule is redesigned through all passes. As a result, the possibility of wire fracture could be considerably reduced and the productivity of final product could be more increased than before.

BangPungTongSung-San is usually perscribed in Hyungsang medicine for those of Yangmyung type, Pung type, those who have inner fever as well as redness of the tip of the nose, and for those with the external shape who tend to have dandruff. Following conclusions were obtained from the treatment of 8 patients suffering from inflammatory dermatitis. The causes of inflammatory dermatitis are mainly wind-fever, poisonous fever of the Samcho, dry-fever, and congenital conditions. The inflammatory dermatitis usually occurre to people who belong to Yangmyung types having vigorous Yangmyung meridian and body heat. Some patients who did not belong to the Yangmyung type were either those with much body heat or having congenital conditions inherited from their parents. There was no difference in the frequency of disease between men and women. The disease occurred at the times bodily conditions were weak or significant physiological changes took place. The term for the treatment required at least 3 months. Three more months are considered to be needed in treatment even after the completion of the remedy observing the return of the disease. The inflammatory dermatitis is easily occurred and recurred to those who belong to Yangmyung type and therefore the best prevention would be appropriate diet and bodily manner in daily life.

Korean ginseng (Panax ginseng C. A. Meyer) has been used as an important medicinal plant in the Orient for a long time. It has been claimed that ginseng has many beneficial bioactive effects on human health, such as antitumor, antistress, antiaging and enhancing immune functions. Red ginseng possibly have new ingredients converted during steaming and dry process from fresh ginseng. Kujeungkupo method which means 9 repetitive steaming and drying process was used for the processes of green tea, Polygonatum odoratum, and Rehmanniae radix preparata. In this study, ingredient conversion of ginseng by 9 repetitive steaming and drying process were investigated measuring conversion efficiency of brown materials, crude lipids, crude proteins and aromatic compounds. Brown materials, as an antioxidant, in red ginseng were produced through non-enzymatic reaction by heat. Repetitive steaming and drying treatments on ginseng root contiunously increased the content of brown materials and the chromaticity. Crude lipids were degraded by heat and converted into volatile aromatic ingredients. Crude lipids were degraded and decreased by 0.52% after the 5th and 7th. Crude proteins were also decomposed and converted to amino acid. Crude proteins after the 9th treatment were decreased by more than 85% as increased times of treatments. A bicyclogermacrene as aromatic material was decreased as increased treatment times, while but a aromatic caramel was increased.

The conductivity test is a measure of electrolytes leakage from plant tissue. The shorter the maturation period after heading was the greater electrical conductivity (EC) of rice seed. The polymer-coated seed was not different in EC compared with non-coated seed. As soaking time of rice seed increased, EC increased gradually. The EC varied from 9.9 to 20.7$\mu$S $cm^{-1}g^{-l}$ for control plots and from 21.3 to 41.7$\mu$S $cm^{-1}g^{-l}$ for heat-killed seeds which were produced by autoclaving seeds at 121$^{\circ}C$ for 20 minutes. The germination speed (the rate of 5th day) of rice seed was 94% at control plot, 83% at low temperature and 20% at high temperature. Besides, germination percentage was 95% for the control, 92% for the low temperature treatment and 39% for the high temperature treatment. The EC was negatively correlated (r=-0.771$^{**}$) with germination percentage at low temperature. Water uptake in seeds of 30, 40, 50 days after heading (DAH) was greater than that of 20 DAH. Plant height of seedlings was 9.84 cm for the control but 4.32 cm for the high temperature treatment, and the tallest for polymer-coated seed. Dry weight of seedlings was 0.841 g for the control and 0.287 g at high temperature. Besides, the polymer-coated seed was heavier than non-coated seed. The number of roots was largest from 40 to 50 DAH and polymer-coated seed, but was decreased from 20 to 30 DAH. The length of roots was 20.52 cm at control plot and 19.89 cm polymer-coated seed but 8.68 cm for the low temperature treatment and 7.28 cm for the high temperature treatment.

In this work, the combustive properties of the swine manure, poultry manure, and mixtures based on the resource recycling-energy were investigated. After the specimens were dried to a constant weight by dry oven, combustive properties were tested by the cone calorimeter (ISO 5660-1). It was found that the peak effective heat of combustion (PEHC) in the swine manure (78.72 MJ/kg) has risen due to more amount of the hydrocabon compared with poultry manure (69.41 MJ/kg), also the swine manure increased both of the higher $CO_2$ production rate (0.1959 g/s) and total smoke release rate (THRR) ($419m^2/m^2$) than those of the poultry manure. However, both of the CO production release (0.0996 kg/kg) and CO production rate (0034 g/s) in the poultry manure increased due to more amount of the inorganic contents compared with swine manure. Thus, the high combustion energy is expected to generate depend on the hydrocarbon content.

Fingerprints deposited on paper found at a fire scene are important evidence for determining a suspect's identity. On the other hand, because the temperature at the fire scene is very high, there are many difficulties in developing fingerprints. This study compared the effectiveness of ninhydrin, DFO, and silver nitrate to develop fingerprints deposited on paper exposed to high temperatures. Using a dry heat press, heat was applied to the paper at $200^{\circ}C$ for various times. Silver nitrate was found to be superior to the others under all conditions. Ninhydrin developed fingerprints weakly compared to DFO and silver nitrate. In addition, the sensitivity of DFO decreased with increasing exposure time. Therefore, it is recommended silver nitrate be used to develop fingerprints deposited on paper found at a fire scene.
