  • In oriental medicine, the skin of the face and the body is the mirror of the viscera and bowels. Skin aging is measured according to the elasticity and glossiness of the skin, which is perceived as a matter of fluid-humor within the realms of oriental medicine. Fluid-humor refers to normal body fluid that makes the skin moist and supple and the hair bright and glossy. If the body is lacking fluid-humor, the hair and skin will be dry and coarse. 'The improvement of fluid-humor (nutrition)' is facilitated based on the oriental physiological change theory for middle-aged women. A new study is therefore necessary to develop oriental herbal cosmetics for young women in their 20s. As yet, there has been no study on the effect of herbal cosmetics formulated for middle-aged women and used by young women in their 20s. This study aims to investigate the effect of 'the improvement of fluid-humor' for the skin of young women in their 20s within the theory of oriental medicine. This kind of study is essential for oriental skin care and the development of diverse oriental herbal cosmetics. To determine the effect of oriental herbal cosmetics on young women in their 20s based on the theory of oriental medicine, which says that a shortage of fluid-humor causes skin aging, this study has examined the skin conditions of young women in their 20s and how satisfied they are with oriental herbal cosmetics through an objective equipment-based measurement and subjective questionnaire survey.

  • EPRI PPM (Performance Prediction Methodology), a method used for the prediction of required thrust of valves, can not be applied to unbalanced-disk globe valves operated in the fluid when the fluid temperature is above $150^{\circ}F$ because the thrust increase caused by the friction between the valve disk and body is not considered in the PPM. In order to apply PPM to the valves, EPRI suggested new friction prediction method to be added in the code. This paper analyzes the applicability of the prediction method comparing the disk-to-body friction load predicted from the method with the measured friction load from the field tests. The maximum values from the prediction method and those obtained from the test were 268lbs and about 1500lbs, respectively. It is included that the prediction method should be improved for the realistic prediction of disk-to-body friction load.

  • Objectives : Electroacupuncture is widely used because of its diverse curative influence. However, its electrical safety is not guaranteed when applied on the human body. Therefore, in this study, we did research on the corrosiveness of electroacupuncture when applied on the body fluid. Methods : We did research using acupuncture needles which were made of STS304 or STS316 and which were coated or not coated in silicone. They were 0.25 mm in diameter and 40 mm in length. We immersed them to the depth of about 1cm in Hank's Solution and gave a stimulus in 120 Hz for 60 minutes. Then, we measured the pH of Hank's solution and mass of needles and observed their shape. Results : Acupuncture needles which were made of STS304 corroded more easily than those which were made of STS316 when they were applied on the human body. Acupuncture needles which were coated in silicone corroded much more easily than those which were not coated in silicone when they were applied on the body fluid. Conclusions : In this study, we did research on the corrosiveness of electroacupuncture when it is applied on the body fluid using several acupuncture needles. We made a conclusion that when acupuncture needles were applied on the body fluid, the coated one made of STS304 corrodes more easily than the uncoated one made of STS316. We hope that additional further researches on the effect of the corrosiveness of an acupuncture needle will be carried out.

  • The maintenance of the osmolality of body fluids within a very narrow physiologic range is possible by water balance mechanisms that control the intake and excretion of water. Main factors of this process are the thirst and antidiuretic hormon arginine vasopressin (AVP), secretion regulated by osmoreceptors in the hypothalamus. Body water is the primary determinant of the osmolality of the extracellular fluid (ECF), disorders of body water homeostasis can be divided into hypo-osmolar disorders, in which there is an excess of body water relative to body solute, and hyperosmolar disorders, in which there is a deficiency of body water relative to body solute. The sodium is the predominant cation in ECF and the volume of ECF is directly proportional to the content of sodium in the body. Disorders of sodium balance, therefore, may be viewed as disorders of ECF volume. This reviews addresses the regulatory mechanisms underlying water and sodium metabolism, the two major determinants of body fluid homeostasis for a good understanding of the pathophysiology and proper management of disorders with disruption of water and sodium balance.

  • This paper presents a numerical evaluation of the launch dynamics and thermo-fluid phenomena for gas generator launch eject system. The existing gas dynamic model for launching eject body used ideal gas and adiabatic assumption with empirical energy loss model. In present study, a turbulent Navier-Stokes solver with CHIMERA mesh is employed to predict the detail unsteady thermo-fluid dynamics for the launched body. The calculation results show that proper grid number is necessary for good agreement with experimental data. The important effects for accurate prediction are a gap distance and thermal boundary condition on the wall. The computational results show good agreement with experiment data.

  • Purpose: The purpose of this study was to compare the fluid intake and output (I&O) measurement methods in order to figure out more effective and easier method for medical patients Methods: 71 hospitalized patients participated in the study. In "liquid only (LO)" method, all amount of water was summed up including any liquid types of food and IV fluids. In "whole food(WF) intake," all liquid and solid food intake and IV fluids were added up. Results: The average amount of fluid intake was 2105.29 ml for LO method and 2523.54 ml for WF method. The average amount of fluid output was 2148.98 ml. The intra-class correlations (ICC) between the intake and output measures by the two different methods was 0.803 and 0.826, respectively. The correlation between the differences of intake/output and body weight change in two different methods was r=.347 (p=.003), and r=.376 (p=.001), respectively. Conclusion: The results of this study indicate that both LO and WF method may be useful in monitoring patients' fluid balance. Given the comparability of using LO over WF, it is suggested that measuring just liquid only intake as the indicator of patient's intake is applicable in clinical setting.

  • Background: Gastroesophageal reflux (GER) has been reported to be a common finding in dogs under general anesthesia. Objectives: The aim of this retrospective study was to assess the esophageal and gastric contents in a population of dogs undergoing computed tomographic myelography (myeloCT) examination and to evaluate the factors influencing the presence of esophageal fluid (gastric content, duration of anesthesia, body position, and intrinsic factors). Methods: Esophageal and gastric contents of 83 non-brachycephalic dogs were retrospectively assessed based on plain and myelo-CT scans. Age, weight, breed, sex, and the time between the 2 computed tomography [CT] scans were included. Results: Esophageal fluid was present in 19% (16/83) of the animals, and 14% (12/83) and 46% (37/83), respectively, had fluid or food material in their stomachs. The frequency of observing esophageal fluid on myelo-CT scans was significantly increased compared with plain CT scans (p = 0.006). The presence of gastric fluid was significantly associated with an increased frequency of observing esophageal fluid compared to other gastric contents (p = 0.049; odds ratio, 3.1). The presence of esophageal fluid was not correlated with alimentary gastric contents (p = 0.17). Increased body weight and duration of anesthesia were significantly associated with an increased frequency of observing esophageal fluid (p = 0.022, p = 0.021). Conclusions: Unlike alimentary gastric contents, fluid gastric contents were correlated with the presence of esophageal fluid upon myelo-CT. The observation of fluid in the esophagus may be consistent with GER. This study provides data additional to pH monitoring studies of GER and may support previous studies recommending shorter pre-anesthetic fasting periods in dogs.

  • In general, metallic bio-materials is more widely used in solid tissue like bone or tooth than flexible tissue such as skin or muscle. Especially, Cobalt Chrome Molybdenum(Co-Cr-Mo), which is used in tooth surgery, has a great corrosion resistance. Because this bio-material is non-toxic in human body, and has a bio-compatibility that the vital reaction is not occurred with tissue in body. However the chemical reaction is occurred by fatal matter that deteriorate the property of material surface in conventional polishing, and it can affect to fatal disease in human body or decrease the material properties such as hardness, yield strength or bio-compatibility. This surface in poor condition can cause development of corrosion or bacteria. In this study, MR fluid polishing is used to minimize the scratch, pit or surface flaws generated in conventional polishing. Surface roughness is measured according to the polishing condition to obtain fine surface condition.

  • Purpose: The purpose of this study was to compare the effects of intravenous fluid warming and skin surface warming on peri-operative body temperature and acid base balance of abdominal surgical patients under general anesthesia. Method: Data collection was performed from January 4th, to May 31, 2004. The intravenous fluid warming(IFW) group(30 elderly patients) was warmed through an IV line by an Animec set to $37^{\circ}C$. The skin surface warming(SSW) group(30 elderly patients) was warmed by a circulating-water blanket set to $38^{\circ}C$ under the back and a 60W heating lamp 40 cm above the chest. The warming continued from induction of general anesthesia to two hours after completion of surgery. Collected data was analyzed using Repeated Measures ANOVA, and Bonferroni methods. Results: SSW was more effective than IFW in preventing hypothermia(p= .043), preventing a decrease of $HCO_3{^-}$(p= .000) and preventing base excess(p= .000) respectively. However, there was no difference in pH between the SSW and IFW(p= .401) groups. Conclusion: We conclude that skin surface warming is more effective in preventing hypothermia, and $HCO_3{^-}$ and base excess during general anesthesia, and returning to normal body temperature after surgery than intravenous fluid warming; however, skin surface warming wasn't able to sustain a normal body temperature in elderly patients undergoing abdominal surgery under general anesthesia.
