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.

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.

Identification of crystallin family proteins in vitreous body in rat endotoxin-induced uveitis: Involvement of crystallin truncation in uveitis pathogenesis

Bahk, Song-Chul,Lee, Sook-Hee,Jang, Jung-Un,Choi, Chang-Uk,Lee, Bok-Soo,Chae, Soo-Cheon,Song, Hye-Jin,Park, Zee-Yong,Yang, Yun-Sik,Chung, Hun-Taeg WILEY-VCH Verlag 2006 Proteomics Vol.6 No.11

<P>Endotoxin-induced uveitis (EIU) is an animal model of acute ocular inflammation. To characterize the mechanism of EIU, we analyzed the infiltration of proteins in the vitreous bodies of rats with EIU and normal rats using 2-DE and micro LC/LC-MS/MS. Twenty spots were identified in vitreous bodies of rats. Eighteen of these spots were members of the crystallin family. The truncated form of beta A4- and beta B2-crystallin were predominant in normal vitreous bodies, but there were intact form of crystallins in lipopolysaccharide-injected rats with EIU. These results suggest that crystallin family proteins are the major group of proteins involved in uveitic vitreous and that C-terminal truncation of beta-crystallins may play a role in EIU-related disease progression.</P>

An angular method of identifying diffractive excitation(DE) events for interactions of a hadron beam in nuclear emulsion is applied to identifying DE events in interactions of heavy ions beams. The "apparent" mean free paths (MEP) of DE processes for ^16O(^28Si) beams are 1.00±0.12, 2.4^_1.6_-0.7, and 2.2±0.4(1.5±0.2)m, respectively, at 200, 60 and 14.6 GeV/nucleon, which corresponds to 20-10% fo the MFP for total inelastic interactions. Distinctive features of diffractively excited nuclei are discussed.

Use of Gamma Correction Pinhole Bone Scans in Trauma

Bahk, Yong-Whee,Chung, Yong-An,Park, Jung-Mee The Korea Society of Nuclear Medicine 2012 핵의학 분자영상 Vol.46 No.1

$^{99m}Tc$-hydroxydiphosphonate (HDP) bone scanning is a classic metabolic nuclear imaging method and the most frequently performed examination. Clinically, it has long been cherished as an indispensable diagnostic screening tool and for monitoring of patients with bone, joint, and soft tissue diseases. The HDP bone scan, the pinhole scan in particular, is known for its ability to detect increased, decreased, or defective tracer uptake along with magnified anatomy. Unfortunately, however, the findings of such uptake changes are not specific in many traumatic bone disorders, especially when lesions are minute and complex. This study discusses the recently introduced gamma correction pinhole bone scan (GCPBS), emphasizing its usefulness in the diagnosis of traumatic bone diseases including occult fractures; cervical sprains; whiplash injury; bone marrow edema; trabecular microfractures; evident, gaping, and stress fractures; and fish vertebra. Indeed, GCPBS can remarkably enhance the diagnostic feasibility of HDP pinhole bone scans by refining the topography, pathologic anatomy, and altered chemical profile of the traumatic diseases in question. The fine and precise depiction of anatomic and metabolic changes in these diseases has been shown to be unique to GCPBS, and they are not appreciated on conventional radiographs, multiple detector CT, or ultrasonographs. It is true that MR imaging can portray proton change, but understandably, it is a manifestation that is common to any bone disease.

Development of a Voltage Measuring System for the Pusan-Hamada Submarine Cable

Bahk, Kyung-Soo 한국해안해양공학회 1991 한국해안해양공학회 논문집 Vol.3 No.4

차동증폭과 A/D(analog-to-digital) 변환 회로를 마이크로프로세서(microprocessor)로 작동되는 데이타로거(data logger)에 연결하여 부산-하마다간의 해저케이블 전압변동을 기록하는 장치를 개발하였다. 이 장치는 저가격, 소형, 저전력소모가 특징이며 계기의 전압드리프트(drift)가 정밀수정되고, 무인자동으로 다량의 자료저장과 모뎀(modem)에 의한 자료전달이 가능하다. 케이블 전압 및 전류 이외에 실내온도와 수은전지 전압을 측정하는데, 이는 온도영향에 따른 오차보정과 장기관 계기안정도를 확인하기 위한 것이다. 이 계기에 의한 관측자료에 의하면 부산해저중계국에서의 전압신호는, 약 0.2 볼트의 일정한 폭의 높은 주파수의 잡음대로 이루어져 있는데, 조석과 비슷한 느린 주기로 약 1볼트 범위내에서 변동한다. 또한, 케이블 전원공급장치는 실내온도가 빠르게 변할 때 많은 영향을 받는 것으로 나타났다. A voltage measuring system specified for the voltage fluctuation of the Pusan-Hamada submarine cable is developed by adding circuits of differential amplification and analog-to-digital conversion to a microprocessor-based data logger with a data modem. This system is charaterized by its small size. no power failure. fully unmanned operation. and precise instrumental drift correction. In addition to the cable voltage and current it measures an ambient temperature and a mercury cell voltage in order to calibrate temperature effect and check its long-term stability. The data acquired by this system show that the voltage signal. comprising fast random noises with a constant width of about 0.2V. fluctuates within a range of about 1V and the fluctuation frequency is similar to that of tidal motion. The source voltage of power feeding equipment (PFE) for the cable system seems to be affected when the room temperature changes rapidly.

The specimens were imaged using Tc-99m hydroxymethylene diphosphonate (HDP) pinhole scan and processed by the gamma correction. After cleansing with 10% formalin solution, injured specimen surface was observed using a surgical microscope to record TMF. Morphological findings shown in the photograph, naive pinhole bone scan, GCPBS, and hematoxylin-eosin (H&E) stain of the specimen were reciprocally correlated for histological verification and the usefulness of suppression and enhancement of Tc-99m HDP uptake was biochemically investigated in TMF and edema and hemorrhage using gamma correction.</P><P>On the one hand, GCPBS was able to depict the calcifying calluses in TMF with enhanced Tc-99m HDP uptake. They were pinpointed, speckled, round, ovoid, rod-like, geographic, and crushed in shape. The smallest callus measured was 0.23 mm in this series. On the other hand, GCPBS biochemically was able to discern the calluses with enhanced high Tc-99m HDP uptake from the normal and edema dipped and hemorrhage irritated trabeculae with washed out uptake.</P><P>Morphobiochemically, GCPBS can clearly depict microfractures in the femoral head produced by femoral neck fracture. It discerns the microcalluses with enhanced Tc-99m HDP uptake from the intact and edema dipped and hemorrhage irritated trabeculae with suppressed washed out Tc-99m HDP uptake. Both conventional pinhole bone scan and gamma correction are useful imaging means to specifically diagnose the microcalluses naturally formed in TMF.</P></▼2>
