이예린의 작품은 군더더기 없이 단순명료한 인터페이스를 가지고 있지만, 내포적 다양성이 풍부하다. 대표적인 사진 작품들은 그림자이긴 하지만, 물에 비친 그림자이기에 거울 같은 반영상이다. 거기에는 재현의 기원이 되는 그림자와 거울의 모델이 동시에 작동한다. 배수가 잘 안되어 하수구로 빠져나가지 못한 물이 고여 생긴 이 순간의 연못은 다른 세상을 담는 틀이 되었다. 현실과의 최소한의 접점을 가지는 상상세계는 회화에서 극대화되고, 드로잉에서는 추상적 요소들로 분해되어 있지만, 사진 작업에서는 절묘한 균형을 이룬다. 현실과 상상은 이원론으로 완전히 분리되어 있기 보다는, 뫼비우스 띠처럼 연결된다. 모태 예술이었던 음악은 무의식과 몸속에 깊숙이 자리하며, 음악뿐 아니라 미술에서도 여러 장르를 두루 섭렵해온 작품은 공共감각적이다. 이예린의 작품 속 허상simulacre은 현실과 닮은 그림자eikônes와 닮지 않은 그림자phantasma가 모두 존재한다. 작가는 미술이라는 우회로를 통해서 순수한 생성의 세계에 가 닿으려고 한다. The works of Ye leen Lee feature simple and clear interfaces, while they imply abundant diversity. Her representative photo works show mirror-like shadows reflected on the surface of the water, embodying the origin of representation with shadows and mirrors. The pond or puddle made of stagnating water that failed to drain becomes a frame for another world. In the works of Lee, the imaginary world having minimal contact points with the reality becomes maximized in paintings, gets disassembled into abstract elements in drawings, and creates a subtle balance in photographs. However, the reality and the imagination are not separated by dualism but connected like a Möbius strip. Since the artist learned music from inside her mother’s womb, music is deeply rooted in her unconsciousness as well as in her body. The works of Lee are synesthetic, for she has experimented with diverse genres of art besides music. The simulacrum in her works contains both eikônes that is close to the reality and phantasm that is far from the reality. Using art as a detour, the artist attempts to reach a pure world of creation.

Nonwovens have been proposed as a sound absorber in applications of home interior textile industry for effective noise control. Honeycomb cell blind textiles have been increasingly used in window covering for noise reduction. In this study, the effect of structural parameters of honeycomb cell-structured spunbond nonwoven on the sound absorption property was investigated. Spunbond nonwovens with various thicknesses, areal densities, and porosities were used, and they were joined in the form of a honeycomb cell structure with various cell widths and cell layering. The sound absorption property of the nonwoven improved with increasing thickness. The porosity of the nonwoven was shown to be proportional to the noise reduction coefficient (NRC). An increased air gap between two layers of the nonwoven shifted the maximum sound absorption coefficient toward a lower frequency range. The honeycomb cell structure was confirmed to contribute to an improvement of the sound absorption property. Layering of the honeycomb cell structure was also shown to be a critical factor in controlling the sound absorption property of the nonwoven.

The purposes of this study were to manufacture sirofil yarn using tencel roving and low melting polyester filaments and to analyze the physical properties of sirofil yarns with yarn count, in order to develop composite yarn for high glossy and luxury textile fabrics. The surface morphology of sirofil yarn was observed with the SEM. Tensile and bending properties of sirofil yarn were examined with the yarn count. The tensile fracture of sirofil yarn was shown with a two-step process. Firstly, tencel yarn having low elongation was broken and then the low melting polyester filaments were fractured with very high elongation. Bending properties of sirofil yarn were measured with the KES-FB. The bending rigidity of sirofil yarn was between that of tencel spun yarn and that of low melting polyester. Also, the surface property of sirofil yarn was evaluated in terms of the hairiness coefficient. It was shown that stress, strain, bending rigidity, bending hysteresis and surface hairiness coefficient of sirofil yarn decreased as yarn count increased.

Objectives: Ethylene oxide (EtO) is classified as a human carcinogen, but EtO is still widely used to sterilize heat-sensitive materials in hospitals. Employees working around sterilizers are exposed to EtO after sterilization. The aim of the present study was to assess the exposure of EtO level, coupled with occupationally induced micronuclei from hospital workers. The influence of genetic polymorphisms of detoxifying genes (GSTT1 and GSTM1) and DNA repair genes (XRCC1 and XRCC3) on the frequencies of micronuclei in relation to exposure of EtO was also investigated. Methods: The study population was composed of 35 occupationally exposed workers to EtO, 18 student controls and 44 unexposed hospital controls in Korea. Exposure to EtO is measured by passive personal samplers. We analyzed the frequencies of micronuclei by performing cytokinesis-block micronucleus assay (CBMN assay) and GSTM1, GSTT1, XRCC1, and XRCC3 were also genotyped by performing polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: The frequencies of micronuclei in EtO exposure group, student controls and hospital controls were $18.00{\pm}7.73$, $10.47{\pm}7.96$ and $13.86{\pm}6.35$ respectively and their differences were statistically significant, but no significant differences according to the level of EtO were observed. There was a dose-response relationship between the frequencies of micronuclei and cumulative dose of EtO, but no significantly differences were observed. We also investigated the influence of genetic polymorphisms (GSTM1, GSTT1, XRCC1, and XRCC3) on the frequencies of micronuclei, but there were no differences in the frequencies of micronuclei by genetic polymorphisms. Conclusions: The frequencies of micronuclei in EtO exposure group was significantly higher than control groups. A dose-response relationship was found between the level of EtO exposure and the frequencies of micronuclei, but no statistically differences were observed. We also found that the frequencies of micronuclei were increased according to cumulative EtO level. There was no association of the genetic GSTM1, GSTT1, XRCC1, and XRCC3 state with the frequency of micronuclei induced by EtO exposure.

Objectives The purpose of this case study was to report improvement of palpitation, epistaxis, nausea, and anorexia after treatment with Dojeokgangki-tang gamibang in a middle-aged woman who has been taking Panax Ginseng continually. Methods Upon beginning her Dojeokgangki-tang gamibang regimen the patient was asked to self-evaluate the degree of discomfort in her symptoms using a using a number scale from 0 (no symptoms) to 10 (most severe). Evaluation of palpitation and chest discomfort was made a high priority. Results The palpitation the patient experienced, and self-evaluated as an "8" on the number scale at the time of her admission to the hospital, had disappeared (become "0") by the fourth day of hospitalization. The numerous symptoms which accompanied her palpitations (chest discomfort, nausea, anorexia, general weakness, weight loss, and depression) also improved accordingly. Conclusions Health functional food can pose serious health risks such as sudden bleeding and palpitations in individuals with pre-existing health problems. One must exercise extreme caution in deciding to take such supplements. As seen in the case of the middle-aged woman, the quality of life of patients who had experienced adverse reactions to such supplements can be treated through the administration of Dojeokgangki-tang gamibang.

Escherichia coli O157:H7 infection has been implicated in a number of outbreaks of illness linked to the consumption of foods. Handling raw meat contaminated with E. coli O157:H7 in the kitchen could easily contaminate the surface of cutting boards. Thus, levels of cross-contamination of E.coli O157:H7 from ground beef to cutting boards made of different materials and effects of cleaning methods on reducing E. coli O157:H7 were evaluated. Four types of cutting boards (wood,polyethylene, polypropylene, and acrylic) were selected and contaminated with ground beef inoculated with E. coli O157:H7. Levels of cross-contaminated E. coli O157:H7 on boards were then evaluated. For evaluation of cleaning methods, wiping with dry paper towel , wet paper towel, alcohol paper towel,chlorine paper towel were used to clean the contaminated cutting boards. Initial population of pathogens was 6.09 log CFU/g in ground beef. After 1 h contamination of the inoculated ground beef on the cutting boards, no significant difference were observed in levels of cross-contaminated E. coli O157:H7 depending on the cleaning materials except for the normal polyethylene surface. Order of efficacy in removing E. coli O157: H7 was as follows: alcohol > chlorine > wet > dry paper towel. Cleaning with alcohol sanitizer appeared as the most effective cleaning method for reducing E. coli O157: H7 population on kitchen cutting boards. These results could be used to develop kitchen safety guidelines for preventing foodborne outbreaks.

Objective: To investigate the diagnostic yield of contrast-enhanced computed tomography (CT) in Crohn’s disease (CD) patients presenting with acute severe lower gastrointestinal bleeding (LGIB), and the role of CT in predicting the risk of rebleeding. Materials and Methods: A consecutive series of 110 CD patients presenting with acute severe LGIB between 2005 and 2016 were analyzed. Among them, 86 patients who had undergone contrast-enhanced CT constituted the study cohort. The diagnostic yield of CT for detecting contrast extravasation was obtained for the entire cohort and compared between different CT techniques. In a subgroup of 62 patients who had undergone CT enterography (CTE) and showed a negative result for extravasation on CTE, the association between various clinical and CTE parameters and the risk of rebleeding during subsequent follow-up was investigated using Cox regression analysis. Results: The diagnostic yield of CT was 10.5% (9 of 86 patients). The yield did not significantly differ between singlephase and multiphase examinations (p > 0.999), or between non-enterographic CT and CTE (p = 0.388). Extensive CD (adjusted hazard ratio [HR], 3.27; 95% confidence interval [CI], 1.09–9.80; p = 0.034) and bowel wall-to-artery enhancement ratio (adjusted HR, 2.81; 95% CI, 1.21–6.54; p = 0.016) were significantly independently associated with increased rebleeding risks, whereas anti-tumor necrosis factor-α therapy after the bleeding independently decreased the risk of rebleeding (adjusted HR, 0.26; 95% CI, 0.07–0.95; p = 0.041). Conclusion: The diagnostic yield of contrast-enhanced CT was not high in CD patients presenting with acute severe LGIB. Nevertheless, even a negative CTE may be beneficial as it can help predict the risk of later rebleeding.

Cotton and polyester fabrics were coated with a hyperbranched polyurethane (HBPU) solution including multi-walled carbon nanotubes (MWNTs) using a spraying method. The MWNT-coated fabrics showed good water repelling properties at $70^{\circ}C$ and room temperature due to presence of well dispersed MWNTs on the fabric surface. The electrical heating effect of the MWNT-coated fabrics was demonstrated when a DC voltage of 10-30 V was applied to the fabrics, which was dependent on the electrical conductivity of the MWNT/HBPU composites. The MWNT coating on the fabric surface by spraying may be a good method for achieving electrical heating and water repellence.
