  • Correct occlusal relationships are part of the successful prosthetic treatment for edentulous patients. Fabrication of complete dentures comprises of clinical and laboratory procedures that should be executed accurately for achieving success with fabricated dentures. Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the final prosthesis. These occlusal errors can be corrected in two ways: i) in patient's mouth ii) by recording new centric relation and remounting dentures on an articulator. The latter method is more feasible because the mobility of denture base on the mucosa in oral cavity does not permit the identification of premature contacts in centric occlusion and tooth guided eccentric excursions. This article describes a modest and effective clinical chair-side remount procedure using customized mounting platforms.

  • The engine excitation forces are considered as major vibration source for the forklift truck, especially in small class. Even though the current engine mounting system designs are acceptable for vibration isolation, the performance of the engine mounting system is still required for the tendency of light weight, higher power and driver's higher vibration requirement. In this paper vibration reduction technique of forklift engine which is supported on rubber mounts is presented. Based on the dynamic model of resilient engine mounting system, design evaluation program is established. The design optimization technique and evaluation method of system properties are discussed. Effects of optimal design are validated through comparison with test results.

  • DIRCM is a device that deception missiles by directing the light source to missile seeker with infra-red laser based turret. The effectiveness of the device is affected by changes of the turret's Field of View (FoV), and also influence of the interference devices determines the effect of the DIRCM's effectiveness. Therefore finding mounting location for DIRCM is critical parameter for the DIRCM's effectiveness. so we applied stiffness review, interference analysis, FoV analysis and simulation analysis method to Multi-purpose helicopter for the find DIRCM location. As a result, in case of 1 DIRCM mounted at helicopters bottom shows 30~40% survivability. case of 2 DIRCM mounted at both side shows 70~80% survivability.

  • To reduce the weight of the car and ensure the safety of the driver while driving, the existing 440 MPa-class mounting bracket was treated at 590MPa to improve collision safety and secure the weight of the vehicle body. The following conclusions were drawn from the tensile test, forming analysis, and springback prediction. In the formability and springback analyses using FLD, it could be confirmed that bending was an essential process because the formability and flatness were much better when bending was added than when bending was not applied. Based on the research results, it was deduced that the mold design was necessary so that the molding was carried out at a strain rate of 20% or less for stable molding.

  • Design sensitivity analysis of a vehicle system is an essential tool for design optimization and trade-off studies. Most optimization algorithms require the derivatives of cost and constraint function with respect to design in order to calculate the next improved design. This paper presents an efficient algorithm application for the design sensitivity analysis, using the direct differentiation method. A mounting area of suspension that welded on chassis frame is analyzed to show the validity and the efficiency of the proposed method.

  • The mounting technology of ceramic candle elements utilizing disk spring was tested in a hot bench unit. Seven SiC candle elements were fixed in three groups by 2, 2, and 3 elements per group. And its performance was investigated in a hot gas stream using oil burned-exhaust gas. The experimental results showed that this mounting method gave a good performance enough to be useful for the particulate removal in the integrated gasification combined cycle (IGCC). Some operational characteristics of the groupfilter were observed.

  • In the development of Chip Mounter(C/M), much interests have risen regarding how to decrease the operation time of mounting the different chips on the printed circuit board(PCB). The existing method to determine the time sequence of teaching C/M was to follow the procedure which was made by the operater. IN this study, a new but effective algorithm has been developed and employed in SCM-130 Chip Mounter and its online programming had reduced the mounting time significantly and provided the basis for the future online CAD/CAM system.

  • 'On the Morbid Pulse of Abdominal Fullness, Cold Mounting, and Abiding Food' in the Chapter 10 of Synopsis of Golden Chamber that enunciates Abdominal Fullness, Cold Mounting, and Abiding Food is related to the stomach and intestines respectively, and is similar to the region and symptom of disease in the light of both abdominal fullness and symptoms of pain. This chapter was united into one because the formula mentioned in this chapter can be applied to three disease patterns. Abdominal fullness shows the symptoms of distention and unease, but judging from the text as well as a specific formula and symptoms, it follows pain. Accordingly Abdominal fullness dealt with in this chapter is the first consideration and it is a kind of a disease pattern attendant on abdominal pain. Cold Mounting does not mean mounting gi disease but means the abdominal pain. The cause of cold mounting is mainly due to insufficiency of yang gi and oversufficiency of cold evil. And the main symptoms of cold mounting follow the severe pain around the naval and sweating, cold of the extremities, pulse deep and tight. Abiding food is of the same meaning such as damage of food today. Abiding food is now referred to as damage of food. Principles which have set forth in this chapter are put to use of the method of ejection in case that abiding food places in the upper part, precipitation in the lower part. The symptoms of abiding food show that the pulse is slight and slippery and the wrist pulse is both superficial and large and rough in applying the pressure, and the cubit pulse is also slight and superficial as well, and that have diarrhea and have little appetite.

  • To attach a fuel tank to an excavator, two sets of mounting plates on which three bosses are attached are welded onto the tank. In this study, the welding process of a fuel tank for an excavator was modeled using a finite element numerical method. The tank was modeled as a simple plate to which the mounting plate or bosses were attached by fillet welding. Thermal and thermo-elasto-plastic analyses of the welding process were carried out to predict the temperature distribution and material distortion during welding, respectively. Three different welding sequences for the tank were also modelled to compare the deformation that occurred due to each welding sequence. The results of the analysis predicted that changing the welding sequence around the mounting plate could not position the boss within the allowable dimensional range. The results also revealed the sequence in which the maximum distortion of the bosses welded onto the tank was 30% less than the maximum distortion due to the other sequences.

  • This study presents the results of conservation treatment and research on a folding screen with embroidered classical Chinese characters "壽" (su) for longevity and "福" (bok) for good fortune in various scripts. The project was conducted as part of the program for supporting overseas Korean galleries in 2016. The present mounting of this ten-panel folding screen was difficult to identify as it had previously been remounted in a modern style. However, clues to the original mounting were discovered during the conservation process. It was revealed that the folding screen was decorated with colors frequently used in Joseon-period, such as teal silk at the top and bottom of each panel and a violet frame. These features provided clues to the original mounting of the folding screen, of which only a few elements have survived. Since this study analyzes only case of one folding screen, further research is required to reveal the method of mounting folding screens applied during this same period.
