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.
Pedicled Anterolateral Thigh Flaps for Reconstruction of Recurrent Trochanteric Pressure Ulcer
Bahk, Sujin,Rhee, Seung Chul,Cho, Sang Hun,Eo, Su Rak The Korean Society for Microsurgery 2015 Archives of reconstructive microsurgery Vol.24 No.1
The reconstruction of recurrent pressure sores is challenging due to a limited set of treatment options and a high risk of flap loss. Successful treatment requires scrupulous surgical planning and a multidisciplinary approach. Although the tensor fascia lata flap is regarded as the standard treatment of choice-it provides sufficient tissue bulk for a deep trochanteric sore defect-plastic surgeons must always consider the potential of recurrence and accordingly save the second-best tissues. With the various applications of anterolateral thigh (ALT) flaps in the reconstructive field, we report two cases wherein an alternative technique was applied, whereby pedicled ALT fasciocutaneous island flaps were used to cover recurrent trochanteric pressure sores. The postoperative course was uneventful without any complications. The flap provided a sound aesthetic result without causing a dog-ear formation or damaging the lower-leg contour. This flap was used as an alternative to myocutaneous flaps, as it can cover a large trochanteric defect, recurrence is minimized, and the local musculature and lower-leg contour are preserved.

In order to set up a baseline of the normal internal architecture of the lumbar discs, 127 lumbar discs of 30 normal adult subjects were studied by the measure set technique. The internal architectures of each disc were classified into 3 types; well-defined, intermediate, and diffuse type. With age, the internal architecture of the lumbar disc changed from the well-defined through the intermediate to diffuse type, representing degenerative change. The diffuse type was most frequently seen in the discs of L4-5 and L5-S1, suggesting the maximum intensity of stress and strain due to weight bearing at these levels.
Ultimate terahertz field enhancement of single nanoslits
Bahk, Young-Mi,Han, Sanghoon,Rhie, Jiyeah,Park, Joohyun,Jeon, Hyeongtag,Park, Namkyoo,Kim, Dai-Sik American Physical Society 2017 Physical Review B Vol.95 No.7
<P>A single metallic slit is the simplest plasmonic structure for basic physical understanding of electromagnetic field confinement. By reducing the gap size, the field enhancement is expected to first go up and then go down when the gap width becomes subnanometer because of the quantum tunneling effects. A fundamental question is whether we reach the classical limit of field enhancement before entering the quantum regime, i.e., whether the quantum effects undercut the highest field enhancement classically possible. Here, by performing terahertz time domain spectroscopy on single slits of widths varying from 1.5 nm to 50 mu m, we show that ultimate field enhancement determined by the wavelength of light and film thickness can be reached before we hit the quantum regime. Our paper paves way toward designing a quantum plasmonic system with maximum control yet without sacrificing the classical field enhancements.</P>

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.
