La evolución poética de Pablo Neruda y el surrealismo

Bahk, Juan-W 서울대학교 스페인중남미연구소 2005 이베로아메리카硏究 Vol.16 No.-

A través del análisis de varios poemas de Residencia en la tierra, La evolución poética de Pablo Neruda y el surrealismo no sólo se ha procurado seguir la gestación de la poesía surrealista del poeta sino que también se ha tratado de verificar la existencia de las características surrealistas en sus obras. Su autor ha querido también mostrar los discursos poéticos provenientes de la nueva poética naciente en España de aquel entonces, ya que por la amistad que tenía con los poetas del grupo poético del 27, Neruda estaba al tanto del cambio de la flamante poesía. Otro aspecto del que no podemos prescindir es que Neruda a los 15 años era conocedor del idioma francés y por ello leía las obras de Apollinaire, Rimbaud y Baudelaire; o sea, Neruda seguía teniendo contacto con los grandes precursores franceses cuyas contribuciones aportaron al nacimiento de la poesía vanguardista del siglo XX. Este estudio es un proceso ininterrumpido de la evolución poética de Pablo Neruda. Todo lo que tenía en su fondo personal, desde su origen humilde como el hijo de un ganadero y ferroviario hasta su carrera política como senador de Chile y cónsul en varios países de cuatro continentes, llega a cuajar muy bien con la constante evolución de su poética. Este trabajo ha trazado el trayecto de Neruda desde su inicio hasta Residencia en la tierra con el objetivo de que entendamos mejor su poesía surrealista.

Depiction of Nidi and Fibrovascular Zones of Osteoid Osteomas Using Gamma-Correction Tc-99m HDP Pinhole Bone Scan and Conventional Radiograph, and Correlation with CT, MRI, and PVC Phantom Imaging

Bahk, Yong-Whee,Kim, Sung-Hoon,Chung, Yong-An,Bahk, Won-Jong,Park, Jung-Mee,Kang, You-Mee,Choi, Woo-Hee,Park, Young-Ha,Sohn, Hyung-Sun,Kim, Byung-Ki,Chung, Soo-Kyo The Korea Society of Nuclear Medicine 2011 핵의학 분자영상 Vol.45 No.1

Purpose For the precise imaging diagnosis of osteoid osteoma (OO), the identification of the nidus and fibrovascular zone (FVZ) is essential. However, the latter sign has received little attention because it is difficult to demonstrate. We applied the recently introduced gamma correction (GC) to depict the FVZ on pinhole bone scan (PBS), conventional radiography (CR), and computed tomography (CT). Nongamma correction MRI was also analyzed for reference. Methods Ten patients with histologically proven diagnoses of OO were enrolled in this retrospective study. PBS, CR, and CTwere processed by GC to demonstrate the nidi and FVZ as distinct yet integrating components of OO. PBS was performed using a 4-mm pinhole collimator 3 h after iv injection of 925 to 1,110MBq (25 to 30mCi) of Tc-99mHDP, and anteroposterior and mediolateral CR and transverse CT were taken according to the standard technique. MRI sequences included T1- and T2-weighted images. For gamma correction, we utilized the Photo Correction Wizard program of ACD Photo Editor v3.1. A team of three qualified nuclear physician-radiologists, two nuclear physicians, and one MRI specialist read bone scans, radiographs, and MRIs of OO according to each specialty, and orthopaedic aspects and histology were reviewed by one qualified orthopedic surgeon and two qualified pathologists, respectively. Each observer first read the images separately with basic information about the aim of the study given and then in concert. Interpretive disagreement was settled by discussion and consensus. Results On pinhole scan, nidi were presented as areas of intense tracer uptake in all cases, and, importantly after GC, a thin ring-like zone with lower tracer uptake became visible in seven out of ten cases. GCCR also revealed a thin lucent zone that circumscribed the nidi in six out of ten cases and GCCT in two of four cases.MRI, without GC, presented nidi with high signal in the center and a thin ring-like zone with low signal in the periphery in five out of six cases. Ring-like zones were 1-2 mm in thickness and circumscribed the nidus as an integrated part and, hence, were morphologically interpreted as FVZ. Histologically, the presence of a variously mineralized FVZ was confirmed in four cases, but individual locusby- locus image-histology correlation could not be accompolished because specimens were fragmentary. In the FVZ, tracer uptake was lower than in nidi, presumably reflecting that bone metabolism in the two parts differs as in their histology. Statistically, no significant correlation existed between the duration of symptoms and imaging demonstrability of the FVZ (Spearman's test r=-0.057, p=0.877), but parallelism existed in the demonstrability of the FVZ among GC PBS, CR, and CT, and non-correction MRI. Conclusions GC was useful to enhance the resolution of PBS, CR, and CT in OO so that both the nidi and FVZ were separately imaged. The use of CG PBS and CR in combination is recommended for the specific diagnosis of OO with information about bone metabolism and anatomical characteristics. PBS and CR are economical and widely available.

Pollicization of the Middle Finger

Bahk, Sujin,Eo, Su Rak,Cho, Sang Hun,Jones, Neil Ford The Korean Society for Microsurgery 2015 Archives of reconstructive microsurgery Vol.24 No.2

Purpose: Pollicization typically involves surgical migration of the index finger to the position of the thumb. This procedure facilitates the conversion of a useless hand into a well-functioning one in patients who are not amenable to the toe-to-hand transfer. However, middle finger pollicization has been rarely reported. Materials and Methods: We reconstructed a thumb by immediate pollicization of the remnants of the middle finger in two patients who sustained a tumor and a trauma, respectively. The former, after cancer ablation was performed, has not been reported literally, and the latter involved free devitalized pollicization of the middle finger using a microsurgical anastomosis. The distal third extensor communis tendon was sutured to the proximal extensor pollicis longus tendon and the distal flexor digitorum superficialis and profundus were sutured to the proximal flexor pollicis longus. The abductor pollicis brevis tendon was sutured to the distal end of the first palmar interosseous muscle. Coaptation of the third digital nerve and the superficial radial nerve branch was performed. Results: Patients showed uneventful postoperative courses without complication such as infection or finger necrosis. Based on the principles of pollicization, a wide range of pinch and grasp movements was successfully restored. They were pleased with the functional and cosmetic results. Conclusion: Although the index finger has been the digit of choice for pollicization, we could also use the middle finger on specific occasions. This procedure provides an excellent option for the reconstruction of a mutilated thumb and could be performed advantageously in a single step.

Plasmon Enhanced Terahertz Emission from Single Layer Graphene

Bahk, Young-Mi,Ramakrishnan, Gopakumar,Choi, Jongho,Song, Hyelynn,Choi, Geunchang,Kim, Yong Hyup,Ahn, Kwang Jun,Kim, Dai-Sik,Planken, Paul C. M. American Chemical Society 2014 ACS NANO Vol.8 No.9

<P>We show that surface plasmons, excited with femtosecond laser pulses on continuous or discontinuous gold substrates, strongly enhance the generation and emission of ultrashort, broadband terahertz pulses from single layer graphene. Without surface plasmon excitation, for graphene on glass, ‘<I>nonresonant laser-pulse-induced photon drag currents</I>’ appear to be responsible for the relatively weak emission of both <I>s</I>- and <I>p</I>-polarized terahertz pulses. For graphene on a discontinuous layer of gold, only the emission of the <I>p</I>-polarized terahertz electric field is enhanced, whereas the <I>s</I>-polarized component remains largely unaffected, suggesting the presence of an additional terahertz generation mechanism. We argue that in the latter case, ‘<I>surface-plasmon-enhanced optical rectification</I>’, made possible by the lack of inversion symmetry at the graphene on gold surface, is responsible for the strongly enhanced emission. The enhancement occurs because the electric field of surface plasmons is localized and enhanced where the graphene is located: at the surface of the metal. We believe that our results point the way to small, thin, and more efficient terahertz photonic devices.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2014/ancac3.2014.8.issue-9/nn5025237/production/images/medium/nn-2014-025237_0007.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn5025237'>ACS Electronic Supporting Info</A></P>

Pinhole Scintigraphic Sign of Chondromalacia in Older Subjects : A Prospective Assessment with Differential Diagnosis

Bahk, Yong Whee,Park, Young Ha,Chung, Soo Kyo,Kim, Sung Hoon,Shinn, Kyung Sub CATHOLIC MEDICAL CENTER 1994 Bulletin of the Clinical Research Institute Vol.22 No.2

A ^99mTc-MDP bone scan is invaluable in the study of bone diaseases especially when it is augmented with pinhole scintigraphy. We wish to describe a previously unknown, specife sign of chondromalacia patellae demonstrated by pinhole scintigraphy in six middle-aged and elderly patients. Noting an increased patellar uptake in a planar spot view, a medial pinhole scintigraphic scan of the patella was taken to detail the uptake pattern using 3-mm or 4-mm aperture pinhole collimator. The uptake pattern was analyzed in terms of location, definition, mode, grade and other associated changes, and correlated with radiographic and computed tomographic scan alterations. The planar views showed patellar uptake to be diffuse and nonlocalizing in five patients and ill-defined and spotty in the remianing patient. In contrast, pinhole scintigraphy revealed a small, spotty uptake well localized in the central retropatellar facet in all but one patient in whom uptake was segmental. a control pinhole scintigraphic study of 16 patients with their patellas involved by osteoarthrits (n= 6), rheumatiod arthritis (n=5) and Reiter's syndrome (n=5) also revealed retropatellar uptake with or without anterior patellar uptake in every patient. The chondromalacia patellae with localized osteolysis or osteopenia accumulated tracer intensely, whereas those without showed mild to moderate uptake. Spotty tracer uptake singly occuring in the central retropatellar facet without other knee joint attention appears pathognomonic of chondromalacia patellae in older patients.

DIFFRACTIVE EXCITATION OF 14.6 A GeV ^28Si NUCLEI IN NUCLEAR EMULSION

Bahk, S.Y.,Park, I.G.,Song, J.S. 慶尙大學校 기초과학연구소 1990 基礎科學硏究所報 Vol.6 No.-

By use of a new angular method (Kim C. O. et al. 1990). forty-nine Diffractive Excitation(DE) events have been identified among 737 inelastic interactions, obtained in tracing 71.69m of tracks of 14.6 A GeV Si nuclei in nuclear emulsion by the along-the-track scanning method. resulting in the 'apparent' MFP of DE interactions of Si at 14.6 A GeV as 1.5±0.2m. Several features of diffractively excited Si nuclei have been compared with those of O and S. DE process may explain occurrence the Centauro event in cosmic rays.

The Papilla of Vater in Normal and Pathological States

Bahk, Yong Whee,Kim, Choon Yul CATHOLIC MEDICAL CENTER 1974 Bulletin of the Clinical Research Institute Vol.2 No.1

The results are shown in Tables and Ⅱ and Ⅲ. The frequency with which the duodenal papilla is visualized in UGIS and HTDG films was 35% and 82.2%, respectively. It is apparent that demonstrability is by far superior in HTDG, although the papilla was quite satisfactorily visualized in approximately one third of the conventional UGIS films. The size of the duodenal papilla in normal UGIS films ranged from 5×4 to 20×14 mm, and from 7×5 to 19×12 mm in HTDG films, with the means being 9×7 and 13×8 mm, respectviely. The duodenal papilla appeared slightly larger in size in HTDG films than in the conventional UGIS films, and this difference in size is apparently due to the higher magnification in HTDG examination. The papilla was located in the middle third of the descending duodenum in 93% and in the lower third in 7%. The papilla was in all but one of the 67 patients with the diseases of the duodeno-pancreatico-biliary complex. The papilla was moderately to markedly enlarged in every case excepting one of the 12 cases of the pancreas head carcinoma. The enlargement was most conspiquous in the patients with pancreatic abscess, and the least change in the patients with CBD stone. It is concluded that HTDG is highly efficient in diagnosing the diseases of the pancreas, CBD, and papilla of Vater per se, although findings are generally not specific of any definitive pathological process.
