  • GLP regulations were initially “promulgated to address assuring the validity of data in the wake of investigations by EPA and FDA during the mid -1970's which revealed that some studies submitted to the agencies had not been conducted in accordance with acceptable laboratory practices.” [1] In the early 1970s, results of an investigation by the FDA in about 40 laboratories revealed many cases of badly managed studies, poor training of personnel and some cases of deliberate fraud. The general findings were that there were poorly trained study directors and study personnel, poorly designed protocols, protocols not followed, procedures not conducted as described, raw data badly collected, data not correctly identified, data without traceability, data not verified and approved by responsible persons, lack of standardised procedures, poor animal husbandry, inadequate characterisation of test items and test systems, inadequate resources, equipment poorly calibrated or otherwise qualified, reports not sufficiently verified, not an accurate account of the actual study, not a proper reflection of raw data and inadequate archiving of data. These problems are not just past history, since they resurface time and time again, even in quite recent times as the experience of GLP inspectors shows [1]. The GLPs specify minimum practices and procedures in order to ensure the quality and integrity of data submitted in accordance with a regulatory requirement

  • In this paper, a microstrip patch antenna was analyzed by using FDTD method. Firstly, the electric field in the microstrip patch antenna was obtained by approximating a Maxwell's equation to a finite difference equation by means of Yee's algorithm. In this case, Mur's 1st approximation and dispersive boundary condition(BBC) were applied to an absorbing boundary condition. We also analyzed a single microstrip patch antenna by using the FDTD method, then calculating the propagative process in the wave of a return loss. Also, as the result that FDTD was applied to 2-array antenna designed to increase the gain of antenna, the measured results was in relatively good accordance with the values calculated by the FDTD method. The calculated impedance, return loss and VSWR were comparatively good. And these results were In relatively good accordance with the measured values.

  • To investigate dyeing behaviors in accordance with dye structure in cold pad batch dyeing of cotton knit, monochlorotriazine-vinylsulfone bifunctional dyes and monofluorotriazine-vinylsulfone bifunctional dyes were prepared. The spectral property and solubility of the dyes were tested and compared with the imported dyes. In addition, exhaustion behaviors of individual and mixed dye solutions were measured to examine the influence of dye structure on dyeing behavior in cold pad batch dyeing. The substantivity, fixation, migration index and half dyeing time were also calculated for further analysis of dyeing behavior of the prepared dyes. As a result, both dyes exhibited the superior solubilities and satisfactory light absorption properties. Also, monofluorotriazine-vinylsulfone bifunctional dyes showed moderate sensitivity to alkalinity and proper kinetic index values compared with the monochlorotriazine-vinylsulfone bifunctional dyes and the imported dyes. The results indicated monofluorotriazine-vinylsulfone bifunctional structure of the dye is suitable for cold pad batch dyeing.

  • This study examines the effects of restaurant attributes on customers' perceptions of price and brand reputation. Four restaurant attributes were used to represent restaurant quality. Multiple regression was conducted to measure the relationships between the four restaurant attributes and price and brand reputation. Further, an independent T-test was used to compare differences between perceptions of locals and tourists with regard to restaurant quality under two categories (price and brand reputation) after they selected a restaurant. Results of this study revealed that residency did not have a significant impact on customers' perceptions of price or brand reputation, whereas restaurant attributes did have an impact. Taste was a predictor of perceived price, whereas service and atmosphere were predictors of brand reputation. In addition, comparison of restaurant attributes between locals and tourists showed that sanitation and service were significantly different in accordance with price and atmosphere, whereas taste and service were significantly different in accordance with brand reputation. Locals showed higher means for each restaurant attribute compared to tourists.

  • This paper presents the variations obtained in heat flow rate and engine performance of a four-stroke cycle Diesel engine when there were changes in the temperature of cooling water, compression ratio, injection timing of fuel, and other factors. Heat dissipation of engine cylinder was calculated by the heat transfer coefficient of Nusselt's empirical equation and the analysis of distribution of temperature in cylinder barrel was obtained by the finite element method of two-dimensional steady state heat conduction. In this experiment, the out side temperature of cylinder liner was measured by the data logger, and the temperature distribution of liner was computed by the analysis of triangular finite element model under the assumption due to surface heat flux of cylinder inner surface. The results obtained by this study are as follows. Under the given operating condition, the temperature distribution of cylinder liner by using finite element method shows that the mean temperature of barrel is in accordance with the experimental results of Eichelberg and temperature difference is lower than 4.23.deg. C. The heat dissipation of engine decrease in accordance with the decrease of piston mean velocity, compression ratio, and the increase of coolant temperature. Influence on the delay of injection timing of fuel brings about the decrease of heat rejection over the cylinder at constant test conditions.

  • Regarding the ocean carrier's responsibility for damage indemnification, both his or her duty of care and reason of legal exemption have been considered important. The International Convention for the Unification of Certain Rules relating to Bills of Lading also provides that the ocean carrier indemnifies for the loss or damage of freight on the basis of the principle of liability with fault. In other words, the carrier assumes responsibility only for the loss or damage of freight which is under his or her control and whose safety must be carefully maintained by him or her. The carrier's duty of care which is required for freight safety in accordance with the convention is associated with two themes, seaworthiness of vessel and freight itself. To make ocean freight shipping effective necessities the seaworthiness of the ship that will conduct the shipping service under its responsibility. This will ultimately lead to making the service impressive to the shipper as freight owner. Thus the purpose of this study is to contribute to more reasonable shipping by the shipowner or the carrier who needs to ensure seaworthiness of vessel, and prevent unseaworthiness that may be incurred in accordance with freight characteristics. For the purpose, this paper reviewed the meaning of seaworthiness of vessel through a juridical approach to its causal relationship with ocean freight shipping.
