Intertextuality of Modern Korean Traditional Costumes Represented in “The Tiger is Coming”

Intertextuality represents the potential inherent in an object by reproducing and expanding the meaning innated in it. This study adopted a philosophic view to analytically examine modernization of Korea traditional costume. Fashion, as a communication medium, transfers its meaning according to different circumstances. Korean traditional clothing also has changed its appearances and has augmented its meanings by deconstructing and combining with other art forms as time passes. Therefore, the purpose of this study is to investigate the intertextuality reflected in modernization of traditional clothing shown in commercial clips of the Korea Tourism Organization; The tiger is coming. The images were collected through the internet and analyzed based on intertextuality of music and dance. The intertextuality of music and dance was identified by analyzing coordination methods and they were analyzed through intertextuality of Time Place Occasion (TPO) and gender. As a result, it shows intertextuality of TPO with music and dance represented in the images is a harmonization of the past and present, west and east, and the public and private. The intertextuality of gender in music and dance is associated with the androgynous style which extracts a popular expression from public contexts. The mix-and-match methods by which the dance team blends the modern with the traditional of Korean costume were successful and such outcomes are most clearly evidenced in the promotional video of Korea Tourism Organization. This study explores the particular importance of intertextuality within modernization of Korea traditional clothes and attention is drawn to ways in which the insight from future studies can be used for creative formation of traditional clothes.

Ultrasound-guided percutaneous insertion of small vascular surgical clips versus dedicated breast mammoclips as markers for breast cancer prior to neo-adjuvant therapy: a prospective randomized controlled trial

AimTo investigate the feasibility of applying small vascular surgical clips as tissue markers for breast cancer in patients scheduled for neoadjuvant chemotherapy (NAC) in comparison with the dedicated breast clips with assessment of their different complications.Patients and methodsThis prospective randomized controlled trial included 160 female patients with breast cancer whose neoadjuvant chemotherapy was required for their management. Patients were randomly allocated into 2 groups; group I for patients who were subjected to the insertion of the small vascular surgical clips, and Group II for patients who were subjected to the insertion of the dedicated breast clips (UltraClips®). Assessment of the feasibility of the application of the vascular surgical clips and detection of the complications of the vascular surgical clips compared to the UltraClip® commercial clips were the endpoints of this study.ResultsVascular surgical clips application had significantly longer duration than the duration of application of the UltraClips® (9.10 ± 2.67 min, and 5.44 ± 1.09 min respectively, P < 0.001). The application of vascular surgical clips was feasible in all patients. There were more incidences of non-deployment (6 patients) and mal-deployment (4 patients) in group I, compared to one patient and 2 patients in group II, respectively. All patients of non-deployment and mal-deployment in both groups had reapplication of other clips successfully. There were no significant differences between the two groups regarding incidence of complications.ConclusionsThe spinal needle/surgical vascular clip technique seems to be a cheap and effective alternative to the dedicated commercial mammoclips when required, with convenient results and minimal complications.

Assessment of low-cost surgical metallic clip placement for tumor localization in BIRDAS VI breast cancer patients undergoing neoadjuvant chemotherapy

BackgroundNeoadjunvant chemotherapy has become a challenging connotation for both surgeons and radiologists due to the high clinical response up to dramatic pathological complete response (pCR) that may hinder proper localization of any residual tumoral tissue. So the radiopaque markers implantation at the tumor bed became a reliable and recommended method for tumor localization before surgical intervention or NAC. Many types of commercial clips and markers are available; however they are relatively of high cost and represent a considerable burden on the governments and the heath institute that made the researchers study cheaper alternatives as standard titanium based cholecystectomy surgical clips for tumor localization.ResultsThe study was conducted on 45 patients where 57 clips were inserted corresponding to number of lesions found in the total number of the patients. The response to Neoadjunvant chemotherapy was recorded and showed that 6 patients (about 13.3%) had complete radiological response after NAC, while 27 patients (60%) had regressive course after the treatment. The low cost surgical clips were evaluated by using sono-mammography and magnetic resonance imaging, and complications that occurred were recorded. Our study showed that in only 2 patients (3.5%) there was difficulty in clip visualization by Ultrasound during post-treatment follow up. In 45 patients, all the inserted clips (100%) were well visualized as small signal void on MRI at both T1WIs and T2WIs sequences, and the primary malignancy was easily visualized on both MRI and sono-mammography not interfering with the image interpretation and judgment. As regards the reported complications, our results revealed that in only 2 patients (3.5%) there was evidence of positive clip migration, while only 2 patients (3.5%) developed hematoma during the procedure as shown by ultrasound, Also 4 patients (7%) complained of pain only shortly after clip insertion. No other significant complications like infection or heat sensation developed either during the procedure or during MRI. The total price of the surgical clips was calculated with average cost of the needle about 10 US$ equivalent to 170 LE Egyptian pounds and the clip about 1.3 US$ or 20 Egyptian pounds, which is considered of lower cost when compared to the commercial breast markers of different companies with an estimated price range for clip = 75–200 US$ (average 90 US$). So insertion of surgical clips saved about 1135 Egyptian pounds equivalent to 73–75 US$ per clip placement.ConclusionWe concluded from our study that the use of breast markers are mandatory before NAC where Surgical clips can safely substitute the commercial tissue markers as tumor localizers as they are effective, safe, well tolerated, easily visualized on imaging and do not interfere with assessment of the treatment response, with no evidence of complications and are of low cost compared with the commercial breast clips.

A Precise Lesion Localization System Using a Magnetometer With Real-Time Baseline Cancellation for Laparoscopic Surgery

Laparoscopic surgery is a technique in which surgeons insert laparoscopic instruments into the body through a small incision and conduct surgical operations. It offers a shorter recovery period, less blood loss, and less postoperative pain than open surgeries. In order to maximize these benefits of this surgery technique, it is important to localize the lesion accurately without palpation, minimizing the surgical area. It is because surgeons cannot palpate the organ during laparoscopic surgeries. For accurate localization, we propose a lesion localization system (LLS). This adopts an endoscopic clip with a small-size magnet as a marker and an improved magnetometer as a probe for measuring the magnetic field from the magnet. The magnetometer, which consists of two Hall sensors, can cancel out the fluctuating magnetic baseline mainly caused by external environments so that it can detect a smaller change in the target magnetic field. As a result, the LLS improves the detection range up to 40 mm while using a weak magnet with a small volume of 17.1 mm3, which is compatible with the use of commercial clip appliers. An error of less than 0.1% is achieved at a distance of 40 mm, and the maximum error is kept below 6% even when the rotation angle is varied to ±90°. This LLS does not cause discomfort to the surgery operation because it uses a marker small enough and does not require external coils.

Valuing innovative endoscopic techniques: prophylactic clip closure after endoscopic resection of large colon polyps

Clip closure of the mucosal defect after resecting large (≥20mm) nonpedunculated colorectal polyps reduces postprocedure bleeding and is cost saving for payers. Clip costs are not reimbursed by payers, posing a major barrier to adoption of this technique in the community. We aimed to determine appropriate clip costs to support broader use of this procedure in practice. We performed budget impact analysis using our recent decision analytic model, comparing prophylactic clip closure with no clip closure on national cost and outcomes data, to determine the maximum feasible clip price while maintaining cost savings in practice. Sensitivity analyses were performed on important clinical factors. In the original model, the baseline postprocedure bleeding risk was 6.8%, increasing cost of care by $614.11 averaged among all patients undergoing large polyp resection without clip closure. Prophylactic clip closure of only large right-sided polyps reduced postprocedure bleeding risk by 70.7% but resulted in cost saving only if the price of clips was $100 or less. Comparatively, prophylactic clip closure of large left-sided polyps had no clinical benefit and was not cost saving. Clip closure strategies focused only on extra-large polyps (≥40mm), or patients taking antithrombotics regardless of polyp characteristics, were only minimally cost saving. Cost savings and maximum tolerated clip prices depended on medical comorbidity, which directly influences the costs of care to manage postprocedure bleeding. Prophylactic clip closure after endoscopic resection of large colon polyps, particularly those in the right colon segment, is cost saving but requires clip costs less than $100. Translating these findings into practice requires gastroenterology practices to obtain reimbursement from payers for improved clinical outcomes and to align commercial clip prices with this clinical indication.

Novel clip applicator for minimally invasive surgery

BackgroundLigation clips are used ubiquitously throughout minimally invasive surgery for apposition of tissues. Their size limits their application beyond ligation of small tubular structures. A novel clip and clip applicator that allows for broad-area clamping and rotation has been developed by our team. The primary aim of this study is to provide preliminary data assessing tensile strength of the clip across apposed segments of bowel.MethodsA comparative study evaluating the maximum load (N) held across two apposed tissues by (a) our novel broad-area clip and (b) a conventional commercial clip was performed. Two sections of porcine bowel were clamped together and the maximum load (N) was measured using a tensile strength material testing machine. A preliminary experiment comparing staple line leak pressures in a porcine model ± clip enforcement of staple line was also conducted. p < 0.05 determined statistical significance.ResultsTwenty-four samples (intervention = 15; control = 9) of porcine bowel annealed by surgical clips were tested. The mean maximum force withheld by the bowel and staples was greater for our novel clip design (2.043 ± 0.831 N) than the control clip (1.080 ± 0.466 N, p = 0.004). Ten staple line (intervention = 5; control = 5) pressures of porcine bowel were measured. There was no statistically significant difference between the leak pressures with clip reinforcement (84.8 mmHg; range 71.8–109.8 mmHg), or without (54.1 mmHg; range 26.3–98.9 mmHg).ConclusionThese preliminary results suggest that our novel clip is able to withstand higher tensile force across tissues compared to a leading commercial clip. A small preliminary trial of effect on leak pressures demonstrated no statistical significance; however, increasing reliability of staple line deformation may be a clinically important finding. Whilst further iteration of product design and clinical testing is required, this product may occupy an important clinical niche through staple line reinforcement, enterotomy closure and other applications.

Multimedia analysis and design: a conceptual framework

The paper proposes a conceptual model inspired to semiotic theories, to be applied to the analysis and design of multimedia. We introduce a meta-model with four levels of semantic aggregation. There results a framework of concepts, relations and processes accounting for the multiple meanings that arise from a multimedia text. We explore the effectiveness of the model by considering four commercial clips by the brand Lancome. Our analysis confirms that the framework is well suited to the analysis, indexing, design of narrative multimedia.

Post–Vacuum-Assisted Stereotactic Core Biopsy Clip Displacement: A Comparison Between Commercially Available Clips and Surgical Clip

PurposeThe placement of localization clips following percutaneous biopsy is a standard practice for a variety of situations. Subsequent clip displacement creates challenges for imaging surveillance and surgical planning, and may cause confusion amongst radiologists and between surgeons and radiologists. Many causes have been attributed for this phenomenon including the commonly accepted “accordion effect.” Herein, we investigate the performance of a low cost surgical clip system against 4 commercially available clips. MethodsWe retrospectively reviewed 2112 patients who underwent stereotactic vacuum-assisted core biopsy followed by clip placement between January 2013 and June 2016. The primary performance parameter compared was displacement >10 mm following vacuum-assisted stereotactic core biopsy. Within the group of clips that had displaced, the magnitude of displacement was compared. ResultsThere was a significant difference in displacement among the clip types (P < .0001) with significant pairwise comparisons between pediatric surgical clips and SecureMark (38% vs 28%; P = .001) and SenoMark (38% vs 27%; P = .0001) in the proportion displaced. The surgical clips showed a significant magnitude of displacement of approximately 25% greater average distance displaced. ConclusionsAs a whole, the commercial clips performed better than the surgical clip after stereotactic vacuum-assisted core biopsy suggesting the surrounding outer component acts to anchor the central clip and minimizes clip displacement. The same should apply to tomosynthesis-guided biopsy.

Three-Dimensional Printing of Surgical Clips: An In Vitro Pilot Study and Trial of Efficacy.

Three-dimensional (3D) printing applications have increased over the past decade. Our objective was to test rapid prototyping of a 3D printed surgical clip for intraoperative use. Our prototype was modeled after the 10 mm Weck® Hem-o-lok® polymer clip (Teleflex, Inc., Wayne, PA). A 3D computer-aided design model of the Hem-o-lok clip was reverse engineered using commercial microscopy and printing was done using an Objet Connex500 multijetting system (Stratasys, Eden Prairie, MN). The initial polymer was Objet VeroWhitePlus RGD835; the addition of Objet TangoBlackPlus FLX980 during the design process improved hinge flexibility. The 3D printed clips were then pressure tested on rubber Penrose tubing and compared in vitro versus commercial Hem-o-lok clips. Initial 3D printed clips were not functional as they split at the hinge upon closure of the clip jaws. Design changes were made to add Objet TangoBlackPlus FLX980 at the hinge to improve flexibility. Additional modifications were made to allow for clips to be compatible with the Hem-o-lok endoscopic clip applier. A total of 50 clips were tested. Fracture rate for the printed clips using a clip applier was 54% (n = 27), whereas none of the commercial Hem-o-lok clips broke upon closure. Of the 23 printed clips that closed, mean leak was at 20.7 κPa (range 4.8-42.7). In contrast, none of the commercial clips leaked, and fill continued until Penrose rupture at mean 46.2 κPa (44.8-47.6). This pilot study demonstrates feasibility of 3D printing functional surgical clips. However, the performance of our first generation clips is poor compared with commercial grade product. Refinement in printers and materials available may allow for customization of such printed surgical instruments that could be economically competitive to purchasing and stocking product.

A commercial system that performs syntactic and semantic analysis during a TV advertising break could facilitate innovative new applications, such as an intelligent set-top box that enhances the ability of viewers to monitor and manage commercials from TV streams.

Constructing and application of multimedia TV-news archives

This paper addresses an integrated information mining techniques for broadcasting TV-news. This utilizes technique from the fields of acoustic, image, and video analysis, for information on news story title, newsman and scene identification. The goal is to construct a compact yet meaningful abstraction of broadcast TV-news, allowing users to browse through large amounts of data in a non-linear fashion with flexibility and efficiency. By adding acoustic analysis, a news program can be partitioned into news and commercial clips, with 90% accuracy on a data set of 400h TV-news recorded off the air from July 2005 to August 2006. By applying speaker identification and/or image detection techniques, each news stories can be segmented with a better accuracy of 95.92%. On-screen captions or subtitles are recognized by OCR techniques to produce the text title of each news stories. The extracted title words can be used to link or to navigate more related news contents on the WWW. In cooperation with facial and scene analysis and recognition techniques, OCR results can provide users with multimodal query on specific news stories. Some experimental results are presented and discussed for the system reliability, performance evaluation and comparison.

Radio frequency versus susceptibility effects of small conductive implants — a systematic MRI study on aneurysm clips at 1.5 and 3 T

Metallic implants cause enlarged artifacts in magnetic resonance (MR) images at higher magnetic fields, B0, due to their magnetic susceptibility. Interactions of conductive material with radio frequency (RF) pulses also change for higher field strengths, B0, due to the frequency dependence of resonance conditions. Systematic measurements on commercial aneurysm clips and simplified copper models were performed in order to investigate both phenomena at 1.5 and 3 T. Six different commercial aneurysm clips made of titanium, straight copper wires and bent copper models were examined in Gd-DTPA-doped water. RF-related effects were measured by adapted 2D and 3D spin-echo sequences. For reliable differentiation from susceptibility-related effects, variable transmitter voltages were applied. In addition, RF-induced heating was controlled by an infrared (IR) camera. At 3 T, a significant RF-induced electric response could be demonstrated for the copper samples and more moderate for one of the commercial clips, dependent on the geometrical structure determining possible resonant RF coupling. Related RF effects could be distinguished from susceptibility artifacts: a signal enhancement at reduced transmitter voltages indicated locally amplified B1-field amplitudes. No significant heating effect could be measured by IR measurements. MR imaging was used to analyze possible RF-induced effects. At 3 T, resonant RF coupling even of small metallic implants has to be considered carefully. Despite a local enhancement of the RF amplitude, no significant RF-induced heating inside the surrounding fluid was found. A direct thermal endangering of patients seems to be unlikely, but extremely high B1-field amplitudes might occur adjacent to the metallic surface with potential nonthermal affection of tissue.

CTOD 측정용 δ5Clip Gage 설계

The flaw assessment method based on δ5 parameter was recently proposed and put to the practical use. However, since it is almost impossible to measure the δ5 by the existing commercial clip gages, we need to develope the specially designed gages which are suitable for that purpose. In this research. a double cantilever type δ5 clip gage with the traveling distance of 4mm was developed by the finite element analysis and the construction of Wheatstone bridge circuit including strain gages. The linearity of developed δ5 clip gage was evaluated by the MTS extensometer calibrator with the proper adapters which allow the δ5 clip gage to sit on the calibrator. Consequently, the δ5 clip gage revealed the good linearity between the output voltage and the traveling distance of gage.
