  • All of the disease which was referred in ${\ulcorner}$Diagnosis and Treatment of the Woonded, Carbuncle, intestinal infection and acute eczema in Synopsis of Golden Chamber${\lrcorner}$ are belong to surgery. Woonded in this chapter, specially, come under in case occur by metal, and spoke that this thing is metal wounded(金瘡). I am considered by something to use Wangbulryuhaengsan(王不留行散) in wound that is not festered, Baenongtang(排膿湯) and Baenongsan(排膿散) in wound that is festered. Carbuncle is one of Venus festering nature file that happen in skin and muscle because blood does not circulate with flag and part's flare, calorification, pain, puffiness are characteristic. Carbuncle is agreed with concept of inflammation of modern medicine. When treat carbuncle, without using surgery medical treatment, used together internal medicine surgery medical treatment. Intestines carbuncle(腸癰) is come in inflammation in abdominal cavity as kind of inflammation, partiality peritoneum festering disease round present cecum as one of inside carbuncle. I think, when treat intestines carbuncle, in case cold and moisture become stasis and heat is less, Uiibujapaedoksan(薏苡附子敗毒散) can be used. Independently of festering, Daehwangmokdantang(大黃收丹湯) can be used in case heat and extravasated blood become stasis. Saliva ulcer on the vulva is comes in impetigo In Case of young child, and is come in Venus eczema in case is general. Prognosis of saliva ulcer on the vulva widespread thing can treat by arm, leg at Lips region, but it does not treat to grow at Lips region from limb, and treatment uses Hwangryunbun(黃連粉)

  • The heat transfer characteristics of a solar high-temperature receiver with heat pipes was investigated by numerical simulation. The concentration ratio of the solar receiver ranges 1000 and the concentrated heat is required to be transported to a certain distance for specific applications. This study deals with internal geometry variation of a solar receiver incorporating high-temperature heat pipe. The isothermal characteristics in the receiver section is of major concern. The diameter of the solar thermal receiver was 120 mm and the length was 400 mm. The angle of receiver end wall was varied between $0^{\circ}$ and $45^{\circ}$. The wall thickness of the heat pipe channel was 4mm and 48 axial channels of the same dimensions were attached to the outer wall of the receiver with even spacing in the circumferential direction. The channels are changed to high-temperature sodium heat pipes. Commercial softwares were employed to deal with the radiative heat transfer inside the receiver cavity and the conduction heat transfer along the channels. The numerical results are compared and analyzed from the view Point of high-temperature solar receiver.

  • Soliton pulse outputs are generated with figure '8' type erbium-doped fiber laser mode-locked by using a fiber loop mirror. The fiber loop mirror consists of an erbium-doped fiber amplifier at the one end of the loop, and 504 m-long dispersion-shifted fiber as a nonlinear medium. By pumping with a $1.48{\mu}m$ wavelength laser diode and adjusting the polarization controllers inside the loop, soliton pulses are generated with 1574 nm center wavelength and 1.2 nm linewidth. The soliton pulses are found randomly spaced within the fundamental period corresponding to cavity round trip time. The autocorrelation trace shows that the pulse width is 2.4 ps, which is in good agreement with the theoretical prediction. The pulsewidth- bandwidth product is found to be 0.348 which means that the pulses are nearly transform-limited.imited.

  • In this paper, the thermoacoustic refrigerating system was implemented and its operation was experimentally verified. The system is composed of several parts ,4 inch midrange speaker, speaker housing, chamber, stack housing, stack of plates, heat exchangers, thin pipe and cavity. The system is filled with He gas at 10 bar and contains T-type thermocouples and condenser microphone for measuring the temperature and pressure inside, respectively. In addition, cooling water is used for protecting speaker from thermal destruction and cooling down the hot heat exchanger. For the experimental verification of the implemented refigerating system, electrical impedance and resonance characteristics were measured. The results showed that it was most efficient to drive the system at 340 Hz. When operated at 340 Hz, $30^\circ{C}$ environments and 50 electical watts, the temperature of the cold region decreased by $16^\circ{C}$. The dissatisfaction mainly comes from the incomplete thermal insulation of the cold region. We also pointed out some guidelines to improve the performance for later study.

  • By comparing ‘Jing Mai(${\ulcorner}$經脈${\lrcorner}$)’ and ‘Jin Fu(${\ulcorner}$禁服${\lrcorner}$)’, we are able to see that ‘Jing Mai’ has adopted many of its aspects from ‘Jin Fu’, which also enables us to conclude that ‘Jing Mai’ was made after 'Jin Fu', with the 'Ren Ying Cun Kou Mai Fa(人迎寸口脈法)‘ being considered important. 'Jing Mai' was made relatively late, during the last days of 'Xi Han(西漢)' or early days of 'Dong Han(東漢)'. Also 'Jing Mai' was written after 'Ying Qi(${\ulcorner}$營氣${\lrcorner}$)’. ‘12 Jing Mai’ in ‘Jing Mai’ is based mainly on 'Yin Yang Shi Yi Mai Jiu Jing(${\ulcorner}$陰陽十一脈灸經${\lrcorner}$)‘ and has also referred to other meridian theories, modifying it again by theories of 'Jin Fu' and 'Ying Qi', forming the 'Jing Mai Lian Huan(經脈連環)' part. The major change in '12 Jing Mai' is that '6 Yang Jing(6陽經)' enters the abdominal and thoracic cavity, directly relating to 'Liu Fu(六腑)'. 'Ben Jing(本經)'s connection to 'Ben Zang' is referred to as 'Shu(屬)' and connection to 'Ben Zang(本臟)' is referred to as 'Lou(絡)', clarifying 'Biao Li Guan Xi(表裏關系)' inside and outslde and 'Zang Fu Xiang He(臟腑相合)' congruency. Looking at the pathological condition view of ‘Jing Mai’, the writer of 'Jing Mai Pian' has renewed it and has erased repeated symptoms of 'Suo Seng Bing(所生病)' that appears in 'Shi Dong Bing(是動病)'. If the wrong adoption of theories of previous generations are corrected and parts which do not comply with the text's original meaning and parts that posterities added are deleted, the ancient acupuncture theory preserved in this book is still a precious treasure.

  • A female Green iguana (Iguana iguana) was brought to the small animal clinic in Hannover Veterinary school because of anorexia and convulsion. Two months ago, the owner bought two iguanas, one female and one male and had to take a female to the one of local small animal clinic because she, born in 19931 didn't eat well and showed the tremor of the legs. The veterinarian suspected it to have a calcium deficiency and gave an injection of calcium and vitamin D3. But still during the last two months, the female iguana did only eat some lettuce while the other male ate lettuce, fruits and commercial cat-food ($Whiskas^{\circledR}$, Effem, Verden). It was not possible to evaluate the rations of these different "food-components". They are kept in the terrarium with water container. By palpation of the abdomen, hard thing like stone was palpated in the mid-region. The blood test wasn't carried out because of the difficulties of getting blood and because of her bad condition. It was firmly diagnosed as cystic calculus through radiography. Since the animal is in shock state already, the prognosis after surgery was bad. It was assumed to be too late to expect its surviving with the surgery carried out or without it. Cystotomy was performed in the cranial ventral paramedian incision in order to preserve the large ventral abdominal vein in the linen alba region. After two stay sutures ("holding suture" ) with 5-0 polyglactin 910 ($Vicryl^{\circledR}, Ethicon$) on the bladder, cystotomy was carried out and the stone inside was removed. Then, the bladder was closed in one-layer sutures. The abdomen was closed in simple interrupted suture with same material after the instillation of 10 ml saline solution into the abdominal cavity. The cystic calculus was in a size of $5.8{\times} 5.O{\times} 3.5 cm$. The analysis of the stone was carried out in two ways which are the infrared spectroscopy of the stone and quick analysis by $Merckognost^{\circledR}$(Diagnostica Merck, Merck). In the result of the infrared spectroscopy, the stone wee composed of 10% ammonium urate and 90% dihydrated uric acid. This iguana wasn't able to survive.n't able to survive.

  • Translucent alumina is a potential candidate for high temperature application as a replacement of the glass or polymer. Recently, due to the increasing demand of high power light emitting diode (LED), there is a growing interest in the translucent alumina. Since the translucent property is very sensitive to the internal defect, such as voids inside or abnormal grain growth of sintered alumina, it is important to fabricate the defect-free product through the fabrication process. Powder injection molding (PIM) has been commonly applied for the fabrication of complex shaped products. Among the many parameters of PIM, the flowability of powder/binder mixture becomes more significant especially for the shape of the cavity with thin thickness. Two different positions of the gate were applied during PIM using the disc type of die. The binder was removed by solvent extraction method and the brown compact was sintered at $1750^{\circ}C$ for 3 hours in a vacuum. The flowability was also simulated using moldflow (MPI 6.0) with two different types of gate. The effect of the flowability of powder/binder mixture on the microstructure of the sintered specimen was studied with the analysis of the simulation result.

  • As the cause and the treatment about gastrointestinal disease has been issued recently, the importance of measuring the pressure in the gastrointestinal tract has been increased. However, the conventional measurement methods of the pressure in the gastrointestinal tract cause the patients' pain and inconvenience as well as an inaccurate pressure measurement. In this paper, the pressure monitoring telemetry system has been designed and implemented for an accurate pressure measurement inside the gastrointestinal tract with minimizing pain and inconvenience. The pressure monitoring telemetry system is composed of a pressure measurement capsule and an external receiver. The capsule has been miniaturized into the same size of a vitamin tablet so that the capsule can be swallowed through the oral cavity. After the capsule acquires and encodes the pressure data in the gastrointestinal tract, the encoded pressure data are modulated by frequency shift keying (FSK) and transmitted with ultrahigh frequency (UHF) band signal to the outside of a body. The performance of the telemetry capsule for monitoring pressure in the gastrointestinal tract is demonstrated by the results of animal in-vivo experiments.

  • Calcium has been associated with improved cold tolerance in many crops. The aim of this study was to investigate the changes in leaf cell $Ca^{2+}$ distribution and cell organelle ultrastructure of loquat (Eriobotrya japonica Lindl.) plants in response to cold stress at $-3^{\circ}C$, using transmission electron microscopy (TEM). Two loquat accessions, Zaozhong 6 (a commercial cultivar) and oakleaf loquat (a wild relative) were used. Cold tolerance, as measured by leaf browning rate, was higher in oakleaf plants, and calcium treatment improved cold tolerance in both species. Cold stress first induced inward transport of $Ca^{2+}$ from the intracellular space. Then, the imported $Ca^{2+}$ was aggregated around the chloroplast membrane, finally entering the chloroplast. This pattern of $Ca^{2+}$ distribution in leaf cells occurred earlier in Zaozhong 6 than in the wild loquat. With increasing time of cold exposure, the chloroplast membranes of Zaozhong 6 leaves were damaged, blurred and even disappeared, while those of wild oakleaf loquat leaves maintained their structure longer. In Zaozhong 6, cold stress induced a clear cavity between poorly structured granal thylakoids and vesicles appearing inside the chloroplast, while in oakleaf leaves cold stress had little effect on the ultrastructure of chloroplasts (although chloroplast membranes looked blurred). Loquat leaves accumulated free calcium ions around chloroplasts in response to cold stress, with earlier calcium accumulation occurring in the cold-sensitive cultivar Zaozhong 6 than in wild oakleaf loquat. These results demonstrate that these two loquat species have differences in both cold tolerance and calcium accumulation dynamics.
