  • The purpose of this study was to estimate the microbial quality of some raw vegetables and to suggest a safer method of sanitization and pre-preparation in foodservice operations. The production of Dotori-muk muchim was monitored from ingredient preparation to final product and during holding at different temperatures. Three sanitization methods were performed during the preparation with crown daisy (tap water, chlorine water, electrolyzed water). The largest reduction of microbial counts was for electrolyzed water (after treatment, total plate counts were decreased to $2.76{\sim}3.76$ Log CFU/g, coliform counts were not detected). In the case before immersed in chlorine water, Performed first washing is larger the effective reduction of microbial counts than or not.

  • Plastic pulleys used for the purpose of power transmission have to very high roundness characteristics. The roundness of plastic pulleys is influenced by many factors. In this study, the effect of molding conditions on the roundness of pulleys was analyzed using a numerical analysis program. To improve the roundness, molding conditions that minimize the amount of deformation of the pulley were studied through an experimental design method. Among the experimental design methods, the Taguchi method was used, and the main molding conditions affecting the deformation of the pulley were the resin temperature and the holding pressure. It was found that the amount of deformation is reduced by about 2.86% when molding with the optimum molding conditions compared to when the optimum molding conditions are not applied.

  • Objectives: TMJ is the joint that connects the mandible to the skull, and it balances the body by holding the skull in the right position. The Meridian flows through the whole body. The objective of this study is to examine and clarify the relationship between the Temporomandibular Joint (TMJ) and the Meridian flow, especially around the TMJ. Methods: We reviewed the literature on the 8 Extra Meridians and the 12 Main Meridians around the TMJ. Results & Conclusion: Eight Extra Meridians keep the balance and harmony of the TMJ, and also play an important role in maintaining equilibrium of Yin and Yang of the whole body. The 12 Main Meridians, twelve Meridian Divergence (12經別) and Meridian Sinew also play an important role in the balance and harmony of the whole body based on the function of the Vicera and Bowels (臟腑). So it is conceivable that the role of TMJ is important in terms of health care.

  • Although bulk metallic glasses have many outstanding aspects in their chemical, mechanical or functional properties, some critical problems still hinder their wide application. The most important one is the brittle nature of them, which is the serious problem to structural application. So, to use viscous flow is now the only competent way to form bulk metallic glass. In this study, we investigated the basic nature of viscous flow of Zr-base bulk metallic glass, vitrelloy 1, in terms of process variables. The results were used to design the thermo-mechanical process composed of heating, holding, pressing, and cooling, which have unique influence on the glass transition and crystallization behavior. We adopted small load scale and dies with nano/micro patterns on them. The results were evaluated using several analytical methods.

  • This study suggests the practical method which can reduce the lead time of the field trial and design of the dies. The virtual manufacturing, with which the die design is evaluated by computer analysis, reveals the impropriety of a design before die makings. Three methods for reducing the die making process occupying over 60% of the automotive development are like follows: First, the crack and wrinkle occurrence can be prevented by virtually adjusting the blank holding force and drawbead force with a computer simulation. Second, the parts which can not remove the forming defects in spite of the adjustment of forming parameters need to modify the part geometry or punch temporary shape. Third, the simulation before field trial, and field trial simulation can be effectively used in die design.

  • Purpose: This study aimed to examine the consultation status and request level of paramedic students. The findings were expected to offer basic data for establishing consultation plans that meet the demands of students. Methods: Questionnaires were distributed among 153 students at two universities, and analyses were conducted based on the responses of 140 students. Results: The preferred counselor was the advising professor. The most common response was that holding two consultation sessions per semester was the most ideal. Regarding topic of consultation, career and employment scored the highest preference. Conclusion: Students had high request levels for consultation. Given the diversity in the themes of consultation, schools, should improve the capacities of advising and other professors in the department for professional consultation.

  • Currently most of underground structures in domestic apartment projects are being designed for parking lot and essential parking area is growing due to the increase in car-holding number per household. Moreover, most underground parking lots of today are combined with basement, therefore a pleasant environment in underground space is strongly needed for the dwellers' use. However, there always occur high percentage of humidity and surface condensation in underground parking lot because of the nature of underground structure and they are having a bad influence on the comfort and health of dwellers. Therfore, this study is planned to compare and examine the porformance and properties of currently used construction methods to prevent condensation and finally present the most suitable method.

  • The bearing capacity of the wall against the eccentric load when the washbasin was attached on the ALC block wall was tested. Test methods are BS EN 14688 and BS 5234-2. Tests in accordance with BS EN 14688 showed that the holding capacity of steel was much stronger and more stable when HA-II (chemical anchor) was used than when the washbasin was fixed using HA-I (plastic anchor). As an experimental result according to the Annex K of BS 5234-2, the bearing capacity of ALC block wall corresponded to the "stage in which the force works(performance grade) 1,500N" for all of the cases where a washbasin is fixed using two types of the wall's dedicated anchors(HA-I and HA-II).

  • Methods for measuring the physical workload of construction workers are classified into posture assessment techniques (i.e., OWAS, RULA, etc.) and physiological measurement techniques (i.e., EMG, heart rate, etc.). The one does not quantify the workload on a specific body part of a worker by considering the weight of the hand tools or materials on hand and time for holding a particular posture. This paper presents a procedure for evaluating a physical demand using the electromyography (EMG) sensor. This study compares the EMG measurement and the posture assessment. The case study is carried out on a masonry operation.

  • This paper presents a double excited three degree-of-freedom (3DOF) motor. The proposed 3DOF motor is designed with a laminated structure, making it easy to manufacture. In addition, it has windings on the stator and rotor, and does not require an expensive permanent magnet. We explain the structure, principle of motion, and design of the proposed motor, and perform an analysis of the static characteristics using the two- and three-dimensional finite element methods (3D FEM). The feasibility of 3D FEM analysis is confirmed by comparing the 3D FEM analysis and experimental results for the rolling and pitching motion. We also confirm the occurrence of holding torque in every motion.
