Objective : The purpose of this study is to arrange the literature about acupuncture therapy on the hemorrhoids and hemorrhoid complicated by anal fistula. Methods : We arrange Huang Di Nei Jing and fifteen kinds of literature about the hemorrhoids and hemorrhoid complicated by anal fistula. Results : 1. The cause of hemorrhoids are overfatigue, overeating, imbalance of stool(const-ipation or diarrhea), uncontrol sexual excess or abstinence, pathgenic factors of wetness, heat, wind, dry, fire, chronical hemorrhoids that has not been treated, and general weakness. 2. Symptom of hemorrhoids is that skin is projected form the nine holes or varicose extension to become hemorrhoid. Hemorrhoids is small nodosity that projected on the anal inter or outer region, and hemorrhoid complicated by anal fistula is pus which comes out form one or some fistula on the anal around inter and outer region. 3. Therapy method of hemorrhoid and hemorrhoid complicated by anal fistula are elimination pathological heat from blood, promote blood flow to remove blood stasis, cold in nature and purge away fire, remove heat form the blood, promote blood flow to remove blood stasis, cold in nature and purge away fire, remove heat from the blood and eliminate dampness, tonify the spleen and replenish Ki, dispel wind and alleviate pain and so forth. Therapy method of hemorrhoid is to give the first consideration to relieve blood: eliminating pathological heat form blood complicated by anal fistula is to tonify the blood first, than after that eliminating pathological heat form blood. About external method are method of fumigation, method of ointment, method of close with medicine, necrotizing method and also operation(injection, bind etc.)was used for treatment. 4. The prescription are Gurgak-hwan, Wypi-hwan, Gunggyi-tang, Jingyochangchul-tang, Jingyobangpung-tang, Mokhyangbinrang-hwan, Ochi-san, Gamihyanso-san, Jojang-hwan, Sinyung-hwan used frequently. 5. food taboo on patient's diet of the hemorrhoid and hemorrhoid complicated by anal fistula are raw grain, cold or dampness food, alcohol, hot food, Singiberis rhizoma recens, Cinnamomi ramulus. 6. Acupuncture therapy on the hemorrhoid and hemorrhoid complicated by anal fistula are, in the first stage eliminating pathological heat form blood and eliminate dampness, and in the long term eliminate dampness, promote and remove meridian energy, remove that form the intestines, dispel channels and collaterals. 7.

1. Objectives: We would know what kind of symptom are different according to Cold and Heat characteristics and health state. We also tried to suggest the development of Sasang Constitution diagnosis model considering of them. 2. Methods: We recruited 1,523 subjects between 10 and 80, excluding individuals who have physically or psychologically serious disease or women in pregnancy in the 21 Oriental Medical Clinics. We seperated group according to Cold and Heat characteristics and health state in CRF(Case Report Form, C-2009-002439) questionnaire and we also developed Sasang constitution diagnosis program to compare agreement according to sex and age group with Cold/Heat and health state one. 3. Results: The number of discordance items are much more than that of accordance items in group seperated according to Cold and Heat, and Health state Sasang constitution agreement rate of Cold/Heat and health state group is higher than that of total group through program. When we diagnosed Sasang constitution with different group characteristics to know the group differences, the disparity rate of the group according to Heat/Cold and Health state is lower than that of the group according to sex and age. 4. Conclusions: As Sasang constitution characteristics are different according to Cold/Heat group and Health state classification, we can upgrade Sasang constitution agreement rate with questionnaire considered of Heat/Cold and health state.

This study was aimed to characterize the laser cutting process for the cold rolled stainless steel sheet. The principal process parameters of the cutting process were applied to both the continuous wave form and the pulsed wave form for the laser output mode. The laser-oxygen cutting process and the laser-nitrogen cutting process were also considered to characterize the quality and efficiency of the cutting process. The laser-oxygen cutting process revealed the better productivity than the laser-nitrogen cutting process, since the laser energy and the exothermic oxidation energy exerted on the laser-oxygen cutting process simultaneously during the entire cutting process. However, the straightness of the cutting section, which was considered as the most important factors, was inferior to that of the laser-nitrogen cutting process due to the formation of chromum oxide on the cutting surface. Frequency and duration of the pulsed wave form act as the main factors for the better quality, When the frequency increased from 100 Hz to 200 Hz and the duty increased from 20% to 40%, the quality factors such as the height of dross and the surface roughness were improved remarkably. The increase in the frequency from 200 Hz to 300 Hz, on the other hand, revealed the less effective in the cutting quality.

This paper presents a analysis of the problem of optimal design of the beams with two I-type cross section shapes. These types of beams are simply supported and subject to pure bending. The strength and stability conditions were formulated and analytically solved in the form of mathematical equations. Both global and selected types of local stability forms were taken into account. The optimization problem was defined as bicriteria. The cross section area of the beam is the first objective function, while the deflection of the beam is the second. The geometric parameters of cross section were selected as the design variables. The set of constraints includes global and local stability conditions, the strength condition, and technological and constructional requirements in the form of geometric relations. The optimization problem was formulated and solved with the help of the Pareto concept of optimality. During the numerical calculations a set of optimal compromise solutions was generated. The numerical procedures include discrete and continuous sets of the design variables. Results of numerical analysis are presented in the form of tables, cross section outlines and diagrams. Results are discussed at the end of the work. These results may be useful for designers in optimal designing of thin-walled beams, increasing information required in the decision-making procedure.

Objectives : The purpose of this study is to understand the meaning and the yin-yang properties of the six qi and the three yin and three yang as well as to understand the relationship between the six qi and the three yin and three yang. Methods : As the concept of six qi is the six climatic influences after all, I tried to grasp the yin and yang properties of the six qi on the basis of the meteorology and Yun Qi theory. Based on this I studied the concept and properties of the three yin and three yang. Results and Conclusions: (1) Among the six qi, cold and heat refer to temperature, dryness and dampness to humidity, and wind and ministerial fire to atmospheric pressure. Wind is an ascending air current while ministerial fire is a descending air current. Therefore, wind, heat, and dampness are the yang, and ministerial fire, dryness, and cold are the yin. (2) Three yin and three yang represent changes of ying and yang of all things following six qi changes. Simple deviation of qi can be described by yin and yang, but consequent changes in form required further developed concepts of three yin and three yang. In other words, the changes of the form caused by wind, heat, and dampness are namely reverting yin, lesser yin, and greater yin respectively, while the changes of the form caused by ministerial fire, dryness, and cold are expressed as lesser yang, yang brightness, and greater yang respectively.

NOx and PM are important air pollutants as vehicle management policy aspect. Medium-duty truck is the main source of the pollutants although the vehicle market share is only 3.5%. National emission portion of NOx and PM form the mobile sourece are 14% and 16% respectively. In this study it was investigated that characteristics of air pollutants emission on medium duty truck equipped with EGR and SCR system. Vehicle's test reflected driving cycle on the chassis dynamometer, and applied test cycle was WHVC(World Harmonized Vehicle Cycle) mode. The test cycle include three segments, represent urban, rural and motorway driving. Based on the test results NOx, PM, HC were less emitted form SCR vehicle than EGR vehicle. And CO was less emitted form EGR vehicle than SCR vehicle due to CO oxidation reaction on DPF surface. And most air pollutants reduced as average vehicle speed increased. Pollutants were less emitted on motorway section than urban and rural sections. But highly NOx emission on motorway section was verified according to increased EGR ratio on fast vehicle speed. HC and CO additional emission was identified as 68%, 58% respectively during SCR vehicle's cold engine start emission test. NOx additional emission was detected by 24% on SCR vehicle's condition of engine cold start while not detected on vehicle equipped with EGR. SCR vehicle's additional NOx emission was derived from low reaction temperature during engine cold start condition. medium-duty truck emission characteristics were investigated in this study and expected to used to improve air pollutants management policy of medium-duty truck equipped with SCR & EGR.

Louis 1. Kahn was a wise architect who learned from history. He developed his own unique architecture by combining his creative sense with design principles and vocabularies that can be found in historical architecture. When restricting a space, he surrounded the space with thick walls as it had been done in historical buildings. The interior space encompassed by this method became a center-oriented and stable space. The objective of this study is to find the characteristics of Kahn's interior spaces by analyzing his projects in terms of space, form, daylight and materials. For this purpose, five works that are considered to have significance from the aspect of interior design were selected and analyzed. The characteristics realized through this study are as follows. A) Spatial features: 1) Generally speaking, each required space has been arranged symmetrically. 2) Being clearly defined as the main space, the subsidiary space, or the service space, each space also was placed very functionally. 3) The space encompassed by thick walls became a center-oriented, stable space. And in most case, it was characterized as a dark space. B) Formative features: 4) The space was defined as a basic solid such as a cylinder, a hexahedron, and an octagonal box, and was developed into a complex shape by the recessed windows. 5) Historical vocabularies such as an arch, a vault, and a dome were reinterpreted in new ways by kahn's own eyes. 6) Haying diverse shapes, the skylights enrich the space in terms of form. C) Daylight feature: 7) The vertical light entering through the skylights creates a solemn and mysterious atmosphere. 8) Given the shadows from the windows that change according to time, the interior space becomes a very vivid space. D) Material feature: 9) Harmonized with cold and smooth materials such as exposed concrete, metal, and glass, the interior space provides a modern atmosphere. 10) Warm appearing wood was used for furniture and part of walls or floors. The effective use of wood takes on a role that is quite complementary to the cold ambience of the smooth and cold materials. 11) With flexibility In building shapes, the concrete becomes the form-endowing materials.
