  • This study was conducted to examine the difference in yield and size of enlarged rhizome according to the kinds of native white lotuses. Four white lotuses (Nelumbo nucifera) were collected from 4 different sites, Jeonbuk Jeonju ('Garam'), Jeonnam Muan ('Hoesan'), Chungnam Buyeo ('Ihnchuisa'), and Chungnam Cheongyang('Cheongyang'). Each enlarged rhizome was planted in an area of 3.3 $m^2$ on 10. April, 2007 and digged out on 19. February, 2008. The yield of enlarged rhizome was in the order of Hoesan (3.0 kg/$m^2$), Cheongyang (2.5 kg/$m^2$), Garam (2.0 kg/$m^2$) and Ihnchuisa (1.0 kg/$m^2$). The number of enlarged rhizomes was in the order of Ihnchuisa (4.9/$m^2$), Garam (4.3/$m^2$), Hoesan (4.2/$m^2$) and Cheongyang (4.1/$m^2$). Total number of nodes in the enlarged rhizomes were much more in the order of Hoesan (17.0/$m^2$), Ihnchuisa (16.0/$m^2$), Cheongyang (15.3/$m^2$) and Garam (14.1/$m^2$). Component ratio of enlarged rhizome length below 50cm for Ihnchuisa, Garam, Hoesan and Cheongyang were 76.3%, 53.0%, 38.2% and 40.3% respectively. Native white lotus had a longer enlarged rhizome in the first node than the other nodes, and their enlarged rhizome length and width became thin. And it became thick and short from the second node of enlarged rhizome. Accordingly the amount of enlarged rhizomes 'Hoesan' was extremely much than others.

  • In many applications like the aircraft or the rockets/missiles, the flow from a nozzle needs to be expanded suddenly in an enlarged duct of larger diameter. The enlarged duct is provided after the nozzle to maximize the thrust created by the flow from the nozzle. When the fluid is suddenly expanded in an enlarged duct, the base pressure is generally lower than the atmospheric pressure, which results in base drag. The objective of this research work is to optimize the length to diameter (L/D) ratio of the enlarged duct using the CFD analysis in the flow field from the supersonic nozzle. The flow from the nozzle drained in an enlarged duct, the thrust, and the base pressure are studied. The Mach numbers for the study were 1.5, 2.0 and 2.5. The nozzle pressure ratios (NPR) of the study were 2, 5 and 8. The L/D ratios of the study were 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10. Based on the results, it is concluded that the L/D ratio should be increased to an optimum value to reattach the flow to an enlarged duct and to increase the thrust. The supersonic suddenly expanded flow field is wave dominant, and the results cannot be generalized. The optimized L/D ratios for various combinations of flow and geometrical parameters are given in the conclusion section.

  • Objectives : This paper analyze several version of Danbangshinpyon(單方新編), a simple medical book that was widely used in the private sector from late Joseon dynasty to Japanese colonial period in Korea. Since it had not only collected the treatments easy to get around but also translated the classical Chinese into Korean, Danbangshinpyon(單方新編) was popular in the environment of poor medical service for the people. Methods : We compared several types of issue having heen popular either in the form of plate printing or as manuscripts until recently. Enlarged edition of Danbangshinpyon(增補單方新編) was edited in 1913, and it had been published a total of 13 times until 1922 with 8th edition. On the other hand, it is regarded that the contents of which are again included into Shinpyonmyobang(新篇妙方) published in 1938. Results : Danbangshinpyon was edited to match the demand for medical care at the time in 1909 on the basis of previously existing Gyungheombang(經驗方) of that time. Taking advantage of the public popularity of Danbangshinpyon, Enlarged edition of Danbangshinpyon was hurriedly constructed with weak consideration of upgrading the content. Shinpyonmyobang(新篇妙方) contains the whole content of Danbangshinpyon(單方新編) in the second half of it. Surveying details in the Shinpyonmyobang, one can find that it had been edited to copytext Enlarged edition of Danbang-shinpyon rather than Danbangshinpyon(單方新編). In other words, it is presumed to have been re-edited after the publication of Enlarged edition of Danbangshinpyon.

  • In this paper, a novel 3-DOF hybrid robot with enlarged workspace is presented for high speed applications. The 3-DOF hybrid robot is made up of one linear actuator and 2-DOF planar parallel robot in series. The actuation consists of one ball-screw to make one linear motion and two rotary ball-screws to transmit rotational motion to 2-DOF parallel robot. The workspace can be enlarged according to ball-screw stroke and the moving inertia can be reduced due to locating all the heavy actuators at the fixed base. The inverse kinematics and workspace analyses are presented. The robot prototype and PC-based control system are developed.

  • Semiconductor industry requires the development of new technology such as 300 mm technology, suitable for manufacturing the next generation dervices. A promising process for realizing 300 mm technology can be achieved by using enlarged microwave plasma chemical vapor deposition (MWCVD) technology. In this work, we used radial line slot antenna for enlarging microwave plasma area, and carried ut the deposition of polysilicon films using enlarged MWCVD for the first time in Korea. The results was as follows. Deposited polysilicon films showed various degrees of crystallinity as well as epitaxy to silicon substrates even at low temperature of $300^{\circ}C$. Deposition rates also controled crystallization behavior and slo deposition rates showed very high crystallinity. It could be said that enlarged MWCVD system and technology was worth to get attraction as one os future technologies for 1 G DRAM era.

  • Facial pores are a visible topographic feature of skin surfaces and are generally the enlarged openings of pilosebaceous follicles. Enlarged facial pores can be a significant cosmetic problem, particularly for women. Recently, gold nanoshell-mediated photothermal therapy (PTT) has been reported to be effective in treating recurrent acne. The treatment of enlarged facial pores with gold nanoshell-mediated PTT produced excellent results with no side effects. The two cases reported here demonstrate the possibility of gold nanoshell-mediated PTT as a safe and effective treatment for enlarged facial pores.

  • Purpose: Median cleft of upper lip is defined as any congenital vertical cleft through the midline of the upper lip. It is uncommon, its embryological pathogenesis remains unexplained to date. The authors hereby report a rare case of median cleft of the upper lip associated with enlarged frenulum and palatal mass. This case offers some understanding of the possible embryologic development of this anomaly. Methods: A 10-month-old boy born by normal vaginal delivery at full-term had a notch in the midline of the upper lip with widened philtrum along with enlarged median frenulum, alveolar cleft, and mass of the hard palate. We performed en bloc resection of the enlarged frenulum and palatal mass and cheiloplasty under general anesthesia. Results: Histological examination revealed that the frenulum and palatal mass was consisted of fibrous tissue with normal mucous membrane. The postoperative course was satisfactory. Conclusion: A rare case of median cleft of the upper lip with associated enlarged frenulum and palatal mass was presented with proper surgical management. The surgical technique includes marginal excision of the clefted epithelium and reconstruction of orbicularis oris muscle, in addition to en bloc resection of the palatal mass and frenulotomy.

  • The purposes of this study were to assess the accuracy of measurements in pre-enlarged canals with small instruments and to compare the accuracies, in enlarged canal, with small size instruments and instruments that match the actual canal diameter using Root ZX, Bingo1020, SmarPex, and e-Magic Finder. Ten extracted teeth were embedded in an alginate model made for testing apex locators. A size 10 file was placed into the root canal until the tip of the file reached the plane of the major diameter of the foramen under a dental operating microscope at the 25 x magnification. The measurement was done with digital caliper and defined as actual length. Electronic length measurement with a size 10 file in pre-enlarged canal was done by reading the index indicating Apex of each device to gain a definite value After completion of canal enlargement to a size 45 file, each difference between actual length and electric measurement value with a size 10 and 40 files in enlarged canal was recorded as L10 and L40. The one-way ANOVA and Scheffe's multiple range tests were computed for analyze the differences among the four apex locators in the same group. The Student's t-test between L10 and L40 of each locator was done. The accuracies of electronic measurements were significantly different among the 4 devices. The file size made no difference on the accuracy of electronic measurement in enlarged canal with same device. The e-Magic Finder was the most accurate device among the 4 apex locators used in this study.
