The objective of the study was to evaluate the bioequivalency between the $Rozid^{TM}$ Tablet (Ilhwa Pharm. Co., Ltd.) as a test formulation and the $Rulid^{TM}$ Tablet (Handok Pharm. Co., Ltd) as a reference formulation. Twenty-four healthy male volunteers were administered the formulations by the randomized Latin square crossover design, and the plasma samples were determined by a high performance liquid chromatography (HPLC) with fluorescence detector. $AUC_t,\;C_{max}\;and\;T_{max}$ were obtained from the time-plasma concentration curves, and log-transformed $AUC_t\;and\;C_{max}$ and log-untransformed $T_{max}$ values for two formulations were compared by statistical tests and analysis of variation. $AUC_t$ was determined to be $63.30{\pm}25.57{\mu}g.hr/ml$ for the test formulation and $64.02{\pm}29.27mg.hr/ml$ for the reference formulation. The mean values of $C_{max}$ for the test and reference formulations were $5.07{\pm}2.14\;and\;5.53{\pm}2.60{\mu}g/ml$, respectively. The $AUC_t,\;and\;C_{max}$ ratios of the test $Rozid^{TM}$ Tablet to the reference $Rulid^{TM}$ Tablet were -1.12% and -8.32%, respectively, showing that the mean differences were satisfied the acceptance criteria within 20%. The results from analysis of variance for log-transformed $AUC_t,\;and\;C_{max}$ indicated that sequence effects between groups were not exerted and 90% confidence limits of the mean differences for $AUC_t,\;and\;C_{max}$ were located in ranges from log 0.80 and log 1.25, satisfying the acceptance criteria of the KFDA bioequivalence. The RozidTM Tablet as the test formulation was considered to be bioequivalent to the RulidTM Tablet used as its reference formulation, based on $AUC_t,\;and\;C_{max}$ values.

The performance of machine tools is qualified by many test procedures given by the national/international standards or respected organisations. Among them, test regarding circular-interpolation accuracy is getting to be one of the important acceptance tests at the production level. Machine tool systems are composed of many mechanical and electronical sub-systems so that it is not easy to improve dynamic performance by examining only one particular part. Instead, overall systematic approach encompassing all the contributing elements is necessary to achieve good results. In this study, measures taken in circular accuracy improvements will be explained case by case.

The potential impact of the methods of sensory science on consumer testing and marketing is reviewed. Areas such as predicting purchase behavior, new approaches to scaling, and cross cultural effects are discussed. An example of the complexity of sensory measurement used to obtain consumer and marketing information is highlighted, using the simple paired preference test as an example.

Design of a degradation test without replacement is considered based on tightened critical value to reduce the evaluation testing time. The sample size, number of inspections, and the critical values are determined to assure the same probability of acceptance when the testing time is reduced to some degree. Photo-diode balance of an optical pickup is analyzed as a case study.

Non-destructive field tests of the concrete has achieved increasing acceptance for the evaluation of existing concrete structures. But the application of this test has not still accomplished to guarantee perfectly the durability of the concrete bridges in Korea. As two major testing methods, this paper recommends the proper empirical relationship between the rebound number together with the ultrasonic pulse velocity and the core strength. Also, this paper recommend the relationships as the aging and as the element.

In this paper, an experimental method of several modal analyses was devised to iify the vibration characteristics of G/T blade in power plants. Also, it is being applied this method to establish the standard category of natural frequency of new developed blades. So acceptance margin to avoid resonance due to nozzle waking force is being established for new blades. It is expected to improve the availability of G/T blades by using the result of this study.

The purpose of this study was to identify the impact of preschoolers' cognitive ability, parenting behavior, and attachment to their mothers and teachers on delay of gratification of preschoolers. The participants of this study were 116 mothers and their 15 teachers of 3-6 year olds from 2 day-care centers in Seoul. T-test, F-test, Correlation analysis, multiple regression analysis were used for data analysis. First, the result of this study showed that preschoolers' delay of gratification by cognitive ability was significant to only motor intelligence. Second, preschoolers' delay of gratification showed positive correlation with warm-acceptance of parenting. Third, preschoolers' delay of gratification by attachment to their mothers was statistically significant, but it was not significant to their teachers. Fourth, the effect of preschoolers' intelligence, parenting behavior, and attachment to their mothers and teachers on delay of gratification was statistically significant to mothers' warm-acceptance($\beta$=.24, p<.05) and was negatively significant to mothers' permissiveness(.$\beta$=-.35, p<.001).

Air injected into the epidural space may spread along the nerves of the paravertebral space. Depending on the location of the air, neurologic complications such as multiradicular syndrome, lumbar root compression, and even paraplegia may occur. However, cases of motor weakness caused by air bubbles after caudal epidural injection are rare. A 44-year-old female patient received a caudal epidural injection after an air-acceptance test. Four hours later, she complained of motor weakness in the right lower extremity and numbness of the S1 dermatome. Magnetic resonance imaging showed no anomalies other than an air bubble measuring 13 mm in length and 0.337 ml in volume positioned near the right S1 root. Her symptoms completely regressed within 48 hours.
