  • This study was conducted to evaluating the antioxidative activities of waffle by natural antioxidants combination (tocopherol, rosemary extract and tea polyphenol) and packaging. Waffle stored at $25^{\circ}C$ and 35$^{\circ}C$ for 70 days were evaluated for acid value, peroxide value and Q$_{10}$ value. Tocopherol, either alone or with rosemary and tea polyphenol, was highly effective in inhibiting lipid oxidation of waffle at $25^{\circ}C$ and 35$^{\circ}C$. Especially among them, rosemary extract exhibited the best synergistic effect, as determined by peroxide value measurement. Waffle was then packaged under the following packing materials (OPP/DL/VMCPP, PET/DL/VMCCP). As the temperature condition, the modified atmosphere decrease in waffle package and increase peroxide value. This result indicated that the PET package was more effective in reducing oxidation than the OPP package.

  • Simple practical design method is proposed for the waffle-iron waveguide filter. The design procedure comprises two steps. The first step is to calculate the K-inverter based on the transformed ABCD parameter from the S parameter for the single window of waffle-iron structure by use of EM S/W tool. The second step is to optimize the size of the windows such that the calculated K inverters may be in accord with the distributed constant prototype filter. In order to validate the design method, a waffle-iron filter for satellite communications over the Ka band is designed and fabricated. The measured results are in good agreement with the calculated ones.

  • The waffle-cone technique is a modified stent application technique, which involves protrusion of the distal portion of a stent into an aneurysm fundus to provide neck support for subsequent coiling. The authors report two cases of wide necked basilar bifurcation aneurysms, which were not amenable to stent assisted coiling, that were treated using the waffle-cone technique with a Solitaire AB stent. A 58-year-old woman presented with severe headache. Brain CT showed subarachnoid hemorrhage and angiography demonstrated a ruptured giant basilar bifurcation aneurysm with broad neck, which was treated with a Solitaire AB stent and coils using the waffle-cone technique. The second case involved an 81-year-old man, who presented with dizziness caused by brain stem infarction. Angiography also demonstrated a large basilar bifurcation unruptured aneurysm with broad neck. Solitaire AB stent deployment using the waffle-cone technique, followed by coiling resulted in near complete obliteration of aneurysm. The waffle-cone technique with a Solitaire AB stent can be a useful alternative to conventional stent application when it is difficult to catheterize bilateral posterior cerebral arteries in patients with a wide-necked basilar bifurcation aneurysm.

  • The effects of added brown rice flour on the quality characteristic of waffle were investigated. Waffle were prepared by the addition of 0%, 25%, 50%, 75% and 100% of brown rice flour on wheat flour. The weight of waffle with brown rice flour ranged from 103.0~107.0 g and that of the control was 100.0 g. The volume of the waffle prepared by adding brown rice flour were 225.0~303.0 mL and that of the control was 307.5 mL. The weight of the waffle increased with increasing brown rice flour concentration, whereas volume and baking loss decreased. The hardness, chewiness (p<0.05) and springiness decreased with the addition of brown rice flour. The Hunter L values of waffle decreased, whereas a and b values increased with the addition of brown rice flour. The result of the sensory evaluation showed that taste and overall acceptability (p<0.05) was the highest for added brown rice flour.

  • The purpose of this presentation is to demonstrate a good results of a second operation, the Waffle procedure, in a patient who did not improve following pericardiectomy. Incomplete parietal pericardiectomy, myocardial fiber atrophy, and unexpected restrictive cardiomyopathy can be considered when the patient\`s symptom does not improve after pericardiectomy is carried out. Constrictive epicarditis is always ruled out. In our case, the patient having constrictive pericarditis combined with pericardial effusion received a pericardiectomy. However, hemodynamics and symptoms of the patient following the operaltion did not improve. However, we experienced a good result following a second operation., the Waffle procedure.

  • This paper presents the results of an experimental study carried out Prestressed Concrete Slab System of WAffle Shape(WAS), was perfomed in order to inverstigate it connection shear behavior according to primary paramaters: connection interval, filling matarial. Specimen is produced in Precast Concrete factories and it comprised one WAS panel and two half WAS panels and then it is filled with packing. Within the ranges of the parameters of the connection details used in this test, connections can develop greater shear strength than the nominal shear strength and the design service load for parking structures.

  • This paper is concerned with the investigation of the structural behavior of waffle structure. Parametric variation on waffle floor thickness, main beam depth and column sizes are imposed to study the effects on mode shapes and natural frequencies of waffle structures. Comparisons between FEM models using shell and 3D-solid elements have also been made. The analysis result has shown that the mode frequencies increase with i) increase in main beam depth at level 2 and ii) decrease in waffle slab thickness at level 3. Both 3D and 2D model shown similar mode shapes. Besides, there is a consistent difference in mode frequencies between 3D and 2D model ranging from 25% to 36%.

  • New layout methods for implementing MOS switches of ultra low channel resistance are presented. These area-effective layout methods include the waffle structure, zipper structure, star zag structure and fingered waffle structure. The design equations for these new layout structures are analyzed. The area-effectiveness of these structures is compared with that of the conventional alternating bar structure. MOS switches of the waffle structure were fabricated using a standard 0.25um CMOS process. The experimental characterization results of the fabricated MOS switches are presented. The analytical comparison and experimental results show that area reductions over 40% are achievable with the new structures.

  • In order to improve the luminous efficiency in ac PDP(Plasma Display Panel), we have suggested the new structures of sustain electrodes with waffle-type barrier ribs and the discharge current for a given pulse voltage has been decreased by eliminating the electrode area which has nothing to do with visible light emission area compared with conventional structure. As a result, the luminous efficiency was improved about 30% compared with the conventional structure.

  • Stent assisted coiling on intracranial broad neck aneurysm has been considered as an effective technique and has made the complex aneurysms amenable to coiling. However, stent navigation and application themselves often have the problems especially when the parent vessel angle (entrance between afferent and efferent vessel) is over 90 degrees. We report here a case of a ruptured broad neck basilar top aneurysm that was successfully coiled using two self-expandable stents (Enterprise and Neuroform) placed in a fashion of modified Y-configured stents with waffle cone technique.
