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.

Using the National Health Information Database of the National Health Insurance Service in Korea for Monitoring Mortality and Life Expectancy at National and Local Levels

Bahk, Jinwook,Kim, Yeon-Yong,Kang, Hee-Yeon,Lee, Jeehye,Kim, Ikhan,Lee, Juyeon,Yun, Sung-Cheol,Park, Jong Heon,Shin, Soon-Ae,Khang, Young-Ho The Korean Academy of Medical Sciences 2017 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.32 No.11

<P>This study explores whether the National Health Information Database (NHID) can be used to monitor health status of entire population in Korea. We calculated the crude mortality rate and life expectancy (LE) at birth across the national, provincial, and municipal levels using the NHID eligibility database from 2004 to 2015, and compared the results with the corresponding values obtained from the Korean Statistical Information Service (KOSIS) of Statistics Korea. The study results showed that the ratio of crude mortality rate between the two data was 0.99. The absolute difference between the LE of the two data was not more than 0.5 years, and did not exceed 0.3 years in gender specific results. The concordance correlation coefficients (CCC) between the crude mortality rates from NHID and the rates from KOSIS ranged 0.997–0.999 among the municipalities. For LE, the CCC between the NHID and KOSIS across the municipalities were 0.990 in 2004–2009 and 0.985 in 2010–2015 among men, and 0.952 in 2004–2009 and 0.914 in 2010–2015 among women, respectively. Overall, the NHID was a good source for monitoring mortality and LE across national, provincial, and municipal levels with the population representativeness of entire Korean population. The results of this study indicate that NHID may well contribute to the national health promotion policy as a part of the health and health equity monitoring system.</P>

Selective enhanced resonances of two asymmetric terahertz nano resonators.

Bahk, Young-Mi,Choi, Jae-Wook,Kyoung, Jisoo,Park, Hyeong-Ryeol,Ahn, Kwang Jun,Kim, Dai-Sik Optical Society of America 2012 Optics express Vol.20 No.23

<P>We studied the electromagnetic interaction between two asymmetric terahertz nano resonators, rectangular holes which have a few hundred micron lengths but nanoscale widths. We report that the dominant resonant transmission of the structures can be modulated by the horizontal distance between two rectangles due to the different oscillation strength of the asymmetric coupling at two different resonance frequencies. Our results are significant for an optimum design of rectangular holes in terahertz frequency regime for applications such as sensitive nanoparticle detection and terahertz filters.</P>

Radiographic Findings in the Pulmonary Diseases of Infants Weighing Under 1500 Grams at Birth

Bahk, Yong Whee,Park, Jeong Mi,Kim, Ok Hwa CATHOLIC MEDICAL CENTER 1991 Bulletin of the Clinical Research Institute Vol.19 No.2

Since the introduction of intensive perinatal care, the survival rate of infants weighing less than 1500 gm at birth has improved substantially. However, the pulmonary diseases remain to be the major causes of the high mortality of these low birth weight infants. In order to systematically assess an epidemiologic distribution of the pulmonary diseases in these very low weight prematures, we have analyzed the chest x-rays of 102 infants weighing less than 1500 gm. These consisted of 30 with extreme low birth weight (ELBW) weighing less than 1000 gm and 72 with very low birth weight (VLBW) weighing 1001~1500 gm. The survival rate of ELBW and VLBW was 10% and 49%, respectively. Seventy of 102 infants had abnormal findings in the chest x-ray. Forty-eight had idiopathic respiratory distress syndrome (IRDS). Seven out of 48 infants with IRDS had persistent ductus arteriosus, and in only 2 (30%) of 7 cases were alive. Endotracheal intubation and assisted ventilation application for the treatment of IRDS resulted in pulmonary interstitial emphysema in 4 infants and pneumothorax and /or pneumomediastinum in 4 infants. Displacement of endotracheal intubation showed lobar and/or unilateral lung atelectasis in 8 infants and a case of accidental dislodgement of intubation tube into the esophagus resulted in air esophagogram and worsened lung aeration. In spite of the development of many sophisticated methods of diagnostic radiology, the chest x-ray was still the most valuable yet simple way of evaluating the pulmonary problems in these extreme and very low birth weight prematures.

We have studied(??) reactions from an emulsion target. The S--2H dibaryon has been searched for by the analysis of the ??? momentum spectrum together with emulsion data. No evidence of H production was observed in the mass range of 1.90-2.16 GeV/c². Upper limits for the production cross section of the H are (0.2-0.6)% of that for the quasifree ??? production at the 90% confidence level.

Pinhole Collimator Scintigraphy in Differential Diagnosis of Metastasis, Fracture and Infection of the Spine

Bahk, Yong Whee,Kim, Ok Hwa,Chung, Soo Kyo CATHOLIC MEDICAL CENTER 1985 Bulletin of the Clinical Research Institute Vol.13 No.1

The purpose of the present communication is to describe findings of diagnostic importance of pinhole-collimator scintigraphy (PCS) in the study of several commonly occurring spinal diseases. Clinical materials consisted of 16 cases of metastatic cancer of the spine, 20 compression fractures, 6 tuberculous spondylitis, and 3 pyogenic spondylitis seen and examined at the Department of Radiology, Catholic Medical College, Seoul, Korea. PCS was performed 4 hours after intravenous injection of 30 mCi MDP-technetium-99m. The gamma camera image was obtained using a pinhole collimator having a 3-mm aperture with the collimator-face-to-target-area distance 5-10 cm. Radioactive counts were accumulated to 500,000 over a period of 25 minutes on average. Our observations show that PCS is very helpful in differentiating cancer metastasis from compression fracture and tuberculous spondylitis from pyogenic spondylitis. The metastatic caner of the spine is characterized by rather diffuse and homogeneous accumulation of radioactivity either throughout the entire vertebral body or in a portion; compression fracture by typical segmental involvement of upper and/or lower and plates; tuberculous spondylitis by homogeneous accumulation; and pyogenic spondylitis by apposing segmental involvement of and plates. This dise space was not narrowed in the former two diseases but it was narrowed in the latter two.

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.

Exposure assessment for Bacillus cereus in ready-to-eat Kimbab selling at stores

Bahk, G.J.,Todd, E.C.D.,Hong, C.H.,Oh, D.H.,Ha, S.D. Butterworths ; Taylor Francis ; Elsevier Science 2007 FOOD CONTROL Vol.18 No.6

Kimbab, which is rolled cooked-rice and other foodstuffs in dried laver, is a representative ready-to-eat (RTE) food in Korea. Bacillus cereus is a significant hazard associated with Kimbab. However, the knowledge of the dose-response relationship for B. cereus is limited, now it is not possible to conduct a full microbial risk assessment. Therefore, our study may be focused on the exposure assessment from retail store to the point of consumption in a Kimbab contaminated with B. cereus. The survey data for preparing and selling of Kimbab, predictive growth model, and consumer eating patterns were combined with probabilistic modeling to simulate the level of B. cereus in store Kimbab at the time of consumption. The estimated contamination levels ranged from as minimum (5% percentile) -3.63logcfu/g, median (50% percentile) 1.39logcfu/g, mean 1.57logcfu/g, and a maximum (95% percentile) 7.31logcfu/g. However, there is always a paucity of data to conduct such full exposure assessments with associated variability and uncertainty, coupled with a validation step. Therefore, we suggest that additional studies to allow for a more realistic and accuracy exposure assessment in the future, based on data gaps we identify.
