  • Background: Left ventricular rupture after acute myocardial infarction is a serious complication with high mortality. Emergency operation is usually the only available treatment. A 76-year-old female with persistent chest pain and syncopal attacks was admitted. Transthoracic echocardiography showed the pericardial effusion and generalized hypokinesia of the inferolateral wall of left ventricle. Coronary angiography revealed a total occlusion of the first diagonal branch. After percutaneous transluminal coronary angioplasty with coronary stent and insertion of intraaortic balloon pump, emergency operation was performed. Under cardiopulmonary bypass and cardiac arrest with cold blood cardioplegia, coronary artery bypass graft with saphenous vein, pericardial patch covering on the rupture area with 6-0 polypropylene running sutures, and fibrin glue compression under the patch were performed. We present a case of left ventricular (free wall) rupture after acute myocardial infarction.

  • In order to understand the influence of light artifact discoloration, priority must be given to the reaction characteristics of the light the materials constituting the product. In this study, we focus on two representative medium, animal glue and linseed oil which constitute the colored layer of the painting relics. This study is based on an accelerated degradation test using two types of light emitting diods (LEDs) with different wavelength characteristics. In the experiments, discoloration appeared markedly in the animal glue and linseed oil under accelerated aging test conditions using Blue LED. Among the two types of LEDs, the degree of discoloration of the material was much higher with the Blue LED having the total radiation flux (mW). This indicates that the discoloration of painting artifacts such as animal glue and linseed oil is more significantly influenced by the total radiation flux (mW) of the light source than the total luminous flux (lm).

  • This study investigated the natural adhesives for ceramics conservation that can be used as a substitution for synthetic resins. Samples were prepared by mixing lacquer with animal glue and the structure and adhesion properties of the samples were analyzed. The structure analysis with FT-IR showed that carbonyl (C=O), amine (N-H) and aromatic (C=C) bonds are increased by adding animal glue on lacquer. Comparing to the viscosity and tensile strength of the sample to the Paraloid B-72 and Araldite rapid type, these natural adhesives can be a substitution for the synthetic resins. Through methodical and intensive study, we expect practical uses of this eco-friendly natural adhesives for ceramics conservation.

  • In this paper, strength and leaching characteristics of water sludge-added lightweight soils(WALS) considering reinforcing materials(waste fishing net, glue treated waste fishing net and geogrid) and layer(1 or 2 layer) were investigated using unconfined compression test and leaching test. Several specimens of water sludge-added lightweight soil consisted of water sludge, cement, and bottom ash were prepared according to flowability. Reinforcing material added into these specimens were waste fishing net and geogrid. A glue treated waste fishing net was also added in order to increase interlocking between soil mixture and waste fishing net. Strength increased in the order of WALS reinforced by waste fishing net, glue treated waste fishing net, and geogrid. Strength of specimen with double layer-reinforcing material was greater than that of specimen with single layer reinforcing material. Leaching result of WALS was also satisfied with standard of ministry of environment.

  • Experimental transplantation of Eklonia stoionifera to natural rock was carried out using adhesive Blue. A plant was attached to an architecture tile ($10\times$10 cm) with the glue, and then the tile was attached to natural rock with underwater glue. Within one month, the tile were fixed to natural rock with an attachment rate of $75\%$, and 5. stoionifera grew up with an insertion rate of $66.7\%$ on the tile. After two months, number of E. stolonifera on the tile decreased. However, the attached plants were regenerated by new stolons, maintaining good growing condition. After seven months,5. stoloaifera increased 6 to 71 individuals. These results indicate that regeneration of plants was mainly affected by the recruitment of stolen around the plant.

  • In order to recycle both water sludge and waste fishing net(WFN), it was investigated in this paper the engineering characteristics of mixtures that consisted of different content of water sludge(0%, 10%, 30%, 50%) and reinforced with waste fishing net(unreinforced, untreated WFN, glue treated WFN). WFN or glue treated WFN(1&2 layers) was also added to the mixture to improve the interlocking between the soil particle and WFN. Several series of laboratory tests such as compaction test, triaxial test, oedometer test, permeability test and leaching test were carried out. The experimental test results indicated that, as water sludge content increases, maximum dry unit weight, cohesion, friction angle, and permeability of the mixture decrease, while optimum moisture content, compression index, expansion index and compressibility increase. For the case of reinforced mixture, its cohesion and friction angle are increased due to the inclusion of WFN and glue treated WFN. Leaching result of mixture was satisfied with standard of ministry of environment.

  • In order to improve the usability of glue, a traditional adhesive material, and the gelation process of seaweed extract carrageenan, a liquid adhesive for wood preservation was prepared by mixing the two materials. The prepared wood adhesive was mixed with a 15 wt% aqueous solution of glue, λ-carrageenan, an antibacterial agent, an antifoaming agent, and the maximum adhesive strength of 1.80 Mpa was confirmed. As a result of comparison, the adhesive strength was superior to that of 5 different types of traditional natural adhesive ingredients (aqueous solution) and 1 type of polyvinyl acetate-based adhesive.

  • Objective: To assess the safety and efficacy of lymphopseudoaneurysm (LPA) glue (n-butyl cyanoacrylate [NBCA]) embolization in the management of chylous ascites after retroperitoneal surgery. Materials and Methods: A retrospective analysis from January 2014 to October 2018 was performed in six patients (4 females and 2 males; mean age, 45.3 ± 14.2 years; range, 26-61 years) who underwent LPA embolization for chylous ascites developing after retroperitoneal surgery involving the perirenal space (four donor nephrectomies, one partial nephrectomy, and one retroperitoneal lymphadenectomy). After placing a percutaneous drainage catheter into the LPA or adjacent lymphocele, embolization was performed by filling the LPA itself with a mixture of glue and Lipiodol (Guerbet). Results: Daily drainage from percutaneously placed drains exceeded 300 mL/day despite medical and surgical treatment (volume: mean, 1173 ± 1098 mL; range, 305-2800 mL). Intranodal lymphangiography was performed in four of the six patients and revealed leakage in 2 patients. Percutaneous embolization of the LPA was successful in all patients using an NBCA and Lipiodol mixture in a ratio of 1:1-1:2 (volume: mean, 4.3 ± 1.1 mL; range, 3-6 mL). Chylous ascites was resolved and the drainage catheter was removed in all patients within 4 days after the procedure (mean, 2.0 ± 1.8 days; range, 0-4 days). No procedure-related complications or recurrence of chylous ascites occurred during a mean follow-up period of 37.3 months (range, 21.1-48.4 months). Conclusion: Glue embolization of LPA has the potential to be a feasible and effective treatment method for the management of chylous ascites after retroperitoneal surgery.

  • Adhesion of CVD W to the TiN glue layer in the blanket W process which is a promising candidate for filing contact holes in subhalfmicron ULSIs has been investigated. The adhesion was enhanced with increasing the W film thickness due to the decrease of the TiN film stress. The adhesion strength was increased by the sputter etching of the TiN surface prior to the W deposition owing to the removal of contaminants and the increase of the surface roughness. The adhesion of the W film to the TiN glue layer property was also improved by Ar ion implantation of the TiN surface owing to the activation of the TiN surface.

  • Ingredients and concentrations of organic solvents in 7 kinds of adhesive sold on the domestic market were qualitatively and quantitatively analysed. Vapor concentrations were also analysed to estimate inhalation concentratins when adhesives were abused to get high. Acetone, methyl ethyl ketone, methyl cyclopenatane, cyclohexane and toluene were identified to be used in domstic adhesives as solvents. When organic solvents of adhesives were vaporized in the vial at the room temprature for 30 mins, concentrations of organic solvents in air were in the range of 5,000~140,000ppm. Among these solvents, toluene, known to have strong hallucination effect, showed 5,000~35,000 ppm. The putative concentration of toluene in case of glue sniffing was estimated to be about 5,000ppm in consideration of glue sniffing circumstances. Toluene was found in all adhesives in this study, even adhesives which toluene was not described in label.
