  • The cholesteatoma is usually associated with chronic purulent otitis media and destroys the surrounding structures and may cause dangerous complications. The cholesteatoma with a positive fistula sign may be observed occasionally, if a softened area is formed in the bony capsule over a semicircular canal which exposed the membranous structure of the canal. Recently, the authors have experienced a case of cholesteatoma combined with labyrin thine fistula in a 22-year old male patient. We present this case with a brief review of the literatures.

  • This paper presents the hydraulic analysis of the air entrainment by the weir types. For the weir types, the stepped weir, the labyrinth weir and the gate underflow weir were selected, and the oxygen transfer efficiency was estimated by the site investigation and the hydraulic model tests. The most effective type for the oxygen transfer was stepped weir The more steps the stepped weir had, the higher efficiency it revealed. Oxygen transfer was proportional to the flow velocity, the Froude number, and the flow discharge in order. Hydraulic model tests showed that a nappe flow occurred at small flow rates. The concurrent condition of a nappe flow and a skimming flow occurred as flow rate increases, nappe flow at the upper part and skimming flow at the lower part. In the region of nappe flow, air inception occurred from the step edges due to flow separation, and air entrainment was made through a free-falling nappe, an air pocket, a nappe impact and a subsequent hydraulic jump. In the region of skimming flow, air entrainment occurred by the variation of water surface over the steps, but it was relatively small compared with nappe flow.

  • Seasonal changes and circadian rhythm of plasma prolactin(PRL) concentration in mammals are mediated by melatonin. Pinealectomy or denervation of the pineal gland produces an increase in plasma PRL level. In the rat placenta several members of the PRL family gene are expressed during the late pregnancy. However, the full spectrum of their expression mechanisms and regulatory factors are not elucidated yet. Present study aimed to investigate the local expression of the melatonin receptor la(Me $l_{la}$ ) gene and the effect of melatonin on expression of prolactin-like protein A(PLP-A), a member of the PRL-family gene in the rat placenta. According to the RT-PCR, northern blot and in situ hybridization experiments, Me $l_{la}$ gene was locally expressed in the rat placenta, Me $l_{la}$ mRNA was localized mainly in the placental junctional and labyrinth zones. Interestingly, junctional zone of the placenta showed strong expression of Me $l_{la}$ at daytime(16:00) than at nighttime(22:00). Melatonin agonist, chlorornelatonin decreased the PLP-A mRNA levels in the rat placenta. These results suggest that melatonin coupled with Me $l_{la}$ , may act as a regulation factor that mediates the expression of the PLP-A gene in the rat placenta.

  • Dizziness is one of the common symptoms in many patients. The disorders of the labyrinth, vestibular nerve, vestibular neclei, or their central connections are responsible for practically all vertigo. Most disorders of the central connections are the vascular diseases and tumors. This study is based on the clinical consideration of one patient who sufferd from the cerebellar infarction and the upper respiratory infection. The patient, 61 - year - old man was diagnosed as the cerebellar infarction has been troubled with dizziness, a headache, a sore throat, a cough etc. The symptoms are classed as the Sanchopungyeul.(上焦風熱) Pungdam(風痰), and we prescribed Qingyanligetang(淸咽利膈湯) for him and his symptoms took a tum for the better.

  • This paper presents the characteristics of internal clearances for the interstage of blades and shaft gland seals on the steam turbine which are installed in tandem compound. Internal clearances was changed when the rotor turned in the cylindrical sleeve bearing due to the generation of oil film wedge. This presented concern is very useful to prevent the rubbing damage of seal edge between the fixed and moving parts in steam turbine due to the misalignment at the rotating and stationary parts. This method is applied for the unbalanced clearances distribution to the left and right sides in the turbine casing. A considerable amount of unbalanced clearances distribution trend is determined according to the rotating speed of rotor, size and type of proceeding bearing, oil viscosity, surface roughness of bearing and shaft, oil temperature, oil pressure and bearing load.

  • This paper was carried out to observe prostaglandin $F_{2{\alpha}}$-induced morphological changes in the placenta. White mice received intramuscular injections of $PGF_{2{\alpha}}$(containing dinoprost tromethamine 0.5mg/ml, Upjohn Co.) in once or twice with doses of 0.1ml on 10th to 18th day of their respective pregnancies, the histological changes of the placentae and ovaries were observed with light microscope. Abortion within 21 to 51 hours following $PGF_{2{\alpha}}$ administration occurred in the pregnant mice. Vacuolization of trophospongial cells, giant cells and myometrium under decidua basalis, spherical acidophilic inclusion bodies of various sixtes in trophospongial cells and giant cells. hydropic degeneration and necrosis of labyrinthine trophoblasts and yolk cells, and infltration of neutrophils in the placenta and the uterus were observed. In addition, there were decrease in glycogen of the placental labyrinth and the visceral yolk sac, but increase in glycogen deposit of mesometrial myometrium. Atrophy and increase in number of large lipid droplets of the luteal cells and proliferation of fibroblasts were also recognized in the corpora lutea.

  • The purpose of this study is to find out the way of embodying architectural concept in Nussbaum Museum for complementing present abstract and generalized research. This study tries to examine the close relationship between a certain concept and Nussbaum museum through analyzing architectural characteristics and searching its principles by concrete application of concept. The Architectural concept "Museum without exit", which Libeskind applied to Nussbaum Museum, is based on the dramatic life of Jewish painter Felix Nussbaum with relation to Holocaust, physical background of site and features of program, Libeskind Applied his architectural concept from the beginning to the most parts of the museum. His new museum subverts notions and logic of general features of existing museums. Libeskind's architectural concepts are especially applied to site plan, massing, circulation and spatial configuration. "Museum without exit" creates labyrinth like circulation based on stories including Nussbaum's life, his painting tendency and circumstances of those days. It also realize sensuous space through spatial shape and light control. Although some critics criticize that this museum is not suitable for paint collection because of overwhelming strength of architectural space. However, considering this museum's function of a kind of Holocaust museum beyond personal art gallery, Libeskind's 'museum without exit' shows effective realization of architectural concept for Jewish painter Felix Nussbaum's museum.

  • This study aims to analyze the design concepts of Libeskind's Jewish museums through their comparisons for figuring out his design intentions and characteristics in the realization process. Libeskind's realized four Jewish museums are chosen for this study. For more concrete study, their extracting and application process are also reviewed. The comparison of his museum designs can be good examples in that they show different design approaches on the same architectural type, Jewish museum, to tell their something in common from differences. He could realize his architectural thoughts and configuration methods made by experimental drawings for the first time as real buildings through a series of Jewish museum projects. The commonness of Libeskind's Jewish museums lie on their sharing design concept of Jewish 'history and memory', especially Holocaust, and realized as in contrast to surroundings and 'labyrinth' of spatial configuration to maximize spectator's experiences. As Libeskind regards museum architecture as a carrier of 'time and place', he tried to reflect surrounding context including places, cities, persons and events about museum programs. As a result, unprecedented museums which are not related to traditional museum systems about circulation and spatial configuration are suggested for users to experience Jewish life and history through architecture.
