Sometimes a researcher with a view of conventional significance testing rejects his/her hypothesis, even through it could have not been rejected with a smaller sample. This can be a logical dilemma for a researcher who wants to "prove" a hypothesis rather than to show discrepancy from a null hypothesis. In this study, a new testing paradigm called equivalence testing via confidence interval will be developed so that it is suitable for the purpose of statistical proof.cal proof.

In this paper, Bayesian hypothesis testing procedures are proposed under the non-informative prior distributions, which can be thought as the Bayesian counterparts of the classical ones in the sense of using the concept of significance level. The performances of proposed procedures are compared with those of classical procedures through several examples.

MPEG-4 ER-BSAC decoder employes a full search method for maximum significance search and arithmetic decoding position search in spectral data decoding procedure. Then the search procedure have the most complexity. This paper proposes the new search method, the maximum significance tree structure, for the optimized implementation of BSAC decoder.

To test simultaneous significance of more than two linear regression coefficients, we can consider multivariate-t tests with critical regions in t-space instead of F-tests where t-values are t-statistics of significance tests of one coefficient. In this paper bivariate-t distributions and bivariate-t tests of two coefficients such as maxmod, minmod, one-tailed maxmod and one-tailed minmod tests are studied. Through the calculation of powers of test, it is learned that in some cases bivariate-t test are more powerful than F-tests.

This purpose of this study was to explore the meaning and significance of experiences encountered by preservice teachers' during their observational practicum at day care centers. This study involved one cohort of 32 junior students who were majoring in early childhood education at a 4-year university. Data was analyzed using qualitative research methodology. The findings were as follows: 1) the meaning and significance of students'experiences related to observing children was to develop a trusting relationship with children and a cooperative relationship with teachers in an unfamiliar context. 2) the meaning and significance of students'experiences in observing children was to understand the children and their circumstance. 3) the meaning and significance of students'experience in observing children was to understand the importance of listening in child-teacher spoken interaction.

The purpose of this study was to contribute to the development of clinical instruction by students ratings of teaching effectiveness in clinical education. The instrument used in this study was teaching effectiveness of clinical nursing by Yu and modified evaluation method by Kern and Mickelson. The results were are follows 1. Among the 12 categorial components of clinical teaching effectiveness, the highest satisfaction was 'encouraging to think for themselves' and the lowest was 'attitude of teacher and evaluation' 2. To compare teaching effectiveness between sex, 'resource for student' and 'professional competence' showed statistical significance. 3. To compare teaching effectiveness among clinical practice stage, 'encouraging' 'role model', 'professional competence', 'organization of subject mater' and 'attitude of teacher and evaluation' showed statistical significance. 5. Interrater ICCs for evaluation method did not showed statistical significance and interitem ICCs showed statistical significance. This article presents goal of clinical education, development of clinical instructor's educational program and a standardized method to measure clinical performance.

AMF(amplitude modulated frequency) is defined as currents in the frequency range 1 to 100Hz. The aim of this study was to determine the effects of blood flow and skin temperature according to different stimulating frequency($1{\sim}30Hz,\;30{\sim}50Hz,\;50{\sim}100Hz$) of interferential currents. The results were as follow; 1. There were statistical significance on the blood flow with IFC 1, IFC 2, and IFC 3 group, and inter-groups(p<0.05). 2. There were statistical significance on the skin temperature with IFC 1 and IFC 3 group, and inter-groups(p<0.05). 3. IFC 1 was more statistical significance than IFC 3 group on blood flow(pP<0.05) 4. There was no statistical significance between IFC 1 and IFC 3 group on skin temperature(p>0.05).

Modeling creep of concrete has been one of the most challenging problems in concrete. Over the years, research has proven the significance of creep and its ability to influence structural behavior through loss of prestress, violation of serviceability limit states or stress redistribution. Because of this, interest in modeling and simulation of creep has grown significantly. A research program was planned to investigate the significance of different factors affecting creep of concrete. This research investigation is divided into two folds: first, an in-depth study of the RILEM creep database and development of a homogenous database that can be used for blind computational analysis. Second: developing a probabilistic Bayesian screening method that enables identifying the significance of the different factors affecting creep of concrete. The probabilistic analysis revealed a group of interacting parameters that seem to significantly influence creep of concrete.

Objectives The purpose of this study is to examine of the effect of Sachunghwan on the liver disease. Methods It was induced liver damage rats by thioacetamide and dosed the extract orally and measured the activity rate of GOT, GPT, ALP and LDH. Results 1. GOT activity was more decreased in the experimental goup than in the control goup. Group I showed continuous significance after 72 hour, Group II was significance after 96 hours. 2. GPT activity was more decreased in the experimental group than in the control group. Group I was effective after 72 hours, but group II was effective after 96 hours. 3. The significance of ALP activity in the Group I and group II was revealed after 72 hours. 4. The significance of LDH activity in the Group I and group II was revealed after 96 hours. Conclusions It was showded that Sachunghwan extract was effective on liver disease.

In order to investigate the effect of Dohongsamultang and Dansameum upon restrain of thorombus formation through the experimental study, following conclusion has been obtained; 1. The number of plateletes was increased in the trial group compared with the control group, revealed significance in both of trial groups. 2. Fibrinogen was increased in trial group compared with control group, but the significance was revealed only in Sample I group of Dohongsamultang. 3. Prothrombin time was shortened in both of trial groups, but the significance was revealed in Sample I group of Dohongsa-multang. 4. FDP was decreased in both of trial groups, but the significance was revealed in Sample I group of Dohongsamultang.
