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.

Surface Tension of Liquid Metals

Bahk, S.M.,Park, M.K. 明知大學校 産業技術硏究所 2004 産業技術硏究所論文集 Vol.23 No.-

Even though liquids are quite mobile and appear to have little strength there are strong cohesive forces of attraction between neighboring atoms. It is these cohesive forces that give rise to surface tension. An interior atom in a liquid is surrounded on all sides and thus subject to attractive forces in all direction. However, an atom on the surface is acted upon by an unbalanced force and is attracted strongly inward.

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.

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.

Morphobiochemical diagnosis of acute trabecular microfractures using gamma correction Tc-99m HDP pinhole bone scan with histopathological verification

An Effect of Island Distance in Developing Insular Coleopteran Communities

Bahk, Junbeom 서울대학교 국토문제연구소 2019 地理學論叢 Vol.65 No.-

In this research, the effect of the relationship between physical environment of islands and species diversity of South Korean insular Coleoptera was calculated, using South Korean natural environment survey data. Island size was directly proportional to species diversity. However, it was also inversely proportional in big inhabited islands. It is because the islands can support larger human population and undergo severe and continuous human disturbance. Island distance was not correlated with species diversity. However, island distance was directly proportional to the number of macropterous species. It suggests that macropterous species have advantage over brachypterous species in terms of reaching far islands and colonizing on their own in case of less outside disturbance. To test the difference of distribution of Coleoptera with different wing length, four islands around Boryeong city in Chungcheongnamdo province were surveyed. 755 samples were collected. Identification result showed the tendency that dominance index was inversely proportional to island distance and the rate of macropterous species. It may be originated from the characteristic of macropterous species such as slow colonization and fewer individuals in restricted area. Therefore, the difference of dispersal ability with wing length may affect species composition of islands. This research can be used as base data when predicting species composition and species diversity of uninvestigated islands.

A New Concept for Efficient Sensitivity Amplification of a QCM Based Immunosensor for TNF-α by Using Modified Magnetic Particles under Applied Magnetic Field

Bahk, Yeon-Kyoung,Kim, Hyung-Hoon,Park, Deog-Su,Chang, Seung-Cheol,Go, Jeung-Sang Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.12

This study introduces a new concept for a simple, efficient and cheap sensitivity amplification of a Quartz Crystal Microbalance (QCM) based immunosensor system for the detection of tumor necrosis factor-alpha (TNF-${\alpha}$, TNF) by using an in-built magnetic system. The frequency shift due to the applied magnetic field was successfully observed on magnetic particles labeled detection antibodies, anti-human TNF-${\alpha}$, which were bound to the immunologically captured TNF-${\alpha}$ on the gold coated quartz crystals. In the present system, the magnitude of frequency shift depends on both the strength of magnetic field and the amount of target antigen applied. Significant signal amplification was observed when the additional built-in residual stress generated by the modified magnetic particles under the magnetic field applied. Used in conjunction with a sandwich type non-competitive immunoassay format, the lower detection limit was calculated to be 25 $ngmL^{-1}$ and showed good linearity up to TNF-${\alpha}$ concentrations as high as 2.0 ${\mu}gmL^{-1}$. The sensitivity, most importantly, was improved up to 4.3 times compared with the same QCM system which was used only an antigen-antibody binding without additional magnetic amplification.
