  • This research examined age differences in the way 3-, 4-, 5-year-old children solve scientific problems involving magnetic and nonmagnetic objects. Their scientific process skills and scientific concepts were examined in 1) hypothesis setting, 2) hypothesis verification and 3) hypothesis application. Data was analyzed by one-way and two-way ANOVA and Scheffe. Children's scientific process skill presented differences by age in each phase of problem solving. That is, the scientific concept level demonstrated by 4-year-olds was higher than that of the 3-year-olds. That of the 5-year-olds was higher than the 4-year-olds. In addition, in all age groups, the children showed a higher level of understanding about magnetic and non-magnetic objects in the hypothesis application phase than in the hypothesis setting phase.

  • This article deals with the one-sided hypothesis testing problem in inverse Gaussian distribution. We propose Bayesian hypothesis testing procedures for the one-sided hypotheses of the shape parameter under the noninformative prior. The noninformative prior is usually improper which yields a calibration problem that makes the Bayes factor to be defined up to a multiplicative constant. So we propose the objective Bayesian hypothesis testing procedures based on the fractional Bayes factor, the median intrinsic Bayes factor and the encompassing intrinsic Bayes factor under the reference prior. Simulation study and a real data example are provided.

  • An important role of statistical analysis in science is interpreting observed data as evidence, that is 'what do the data say?'. Although standard statistical methods (hypothesis testing, estimation, confidence intervals) are routinely used for this purpose, the theory behind those methods contains no defined concept of evidence and no answer to the basic question 'when is it correct to say that a given body of data represent evidence supporting one statistical hypothesis against another?' (Royall, 1997). In this article, we use likelihood ratios to measure evidence provided by record values in favor of a hypothesis and against an alternative. This hypothesis is concerned on mean of an exponential model and prediction of future record values.

Review on Problems with Null Hypothesis Significance Testing in Dental Research and Its Alternatives (치의학 연구에서 귀무가설 유의성 검정의 문제점과 대안에 관한 고찰)

  • There are many problems in evaluating study results by p value in null hypothesis testing for dental research. It is a logical fallacy to conclude that the null hypothesis is true when the it is not rejected. There are much serious misunderstanding about p value, and researchers should be cautious about interpreting p value in writing papers. As alternatives to complement or replace the null hypothesis significance testing, effect size, confidence interval, and Bayesian statistics are introduced.

  • This paper investigates children's comprehension and production of demonstrative pronouns (DPs), 'zhege' (this) and 'nage' (that), in Mandarin Chinese. Subjects are children of ages three, four, five and six. Based on the results of the present experiment, children's developmental stages and the corresponding age grading are provided. Also, the present study incorporates a physical clue into the experiment. The result suggests that in the acquisition of deixis children rely highly on physical context to work out the meaning distinction. In addition, Piaget's egocentrism hypothesis and H. Clark's marking hypothesis are examined in the study. The result seems to support the egocentrism hypothesis. Subjects under the age of six do fail to shift the deictic center when they and the experimenter have a different perspective. As for the marking hypothesis, the study seems to challenge the hypothesis. The result shows that children actually performed better on the marked term 'zhege' than the unmarked member 'nage'.

  • This paper proposes an algorithm capable of detecting vehicles in front or in rear using a monocular camera installed in a vehicle. The vehicle detection has been regarded as an important part of intelligent vehicle technologies. The proposed algorithm is mainly composed of two parts: 1)hypothesis generation of vehicles, and 2)hypothesis verification. The hypotheses of vehicles are generated by the analysis of vertical and horizontal edges and the detection of symmetry axis. The hypothesis verification, which determines vehicles among hypotheses, is done by the AdaBoost algorithm. The proposed algorithm is proven to be effective through experiments performed on various images captured on the roads.

  • We study confirmed the relationship between the adversity index, entrepreneurial orientation, and organizational learning competency perceived by organizational members as follows. First, the adversity index showed a positive (+) effect on entrepreneurial orientation (hypothesis 1) and organizational learning competency (hypothesis 2). Second, the entrepreneurial orientation was statistically significant in organizational learning competency (hypothesis 3). Third, the partial mediating role of entrepreneurial orientation (Hypothesis 4) was confirmed in the process of the adversity index affecting organizational learning competency. Meanwhile, the main implications of this study are as follows. First, it is the aspect that provides additional theoretical implications in the reality that studies on the adversity index and entrepreneurial orientation that affect organizational learning competency are lacking. Second, it is the aspect that the importance of adversity index and start-up orientation was confirmed in improving organizational learning competency based on securing differentiated competitiveness for the advancement of the organization's sustainability management system. In addition, it is the aspect of drawing practical implications for strategic human resource management and human resource development to systematically improve it.

  • This study aims to prepare a solution necessary for boosting the consumption of environment-friendly agricultural products, positively reflecting consumers' opinions that expect supplies of safe agricultural products to secure the domestic farms producing environment-friendly agricultural products and at the same time, to meet consumers' needs. As a result of the hypothesis testing, of the subjective knowledge in Hypothesis 1, product knowledge had an impact on attitude, while purchase knowledge and use knowledge after purchase were not significant. Of the subjective knowledge in Hypothesis 2, purchase knowledge and product knowledge had significant impacts on purchase intention. Brand image in Hypothesis 3 had a significant impact on attitude, while brand image in Hypothesis 4 had a significant impact on purchase intention. As a result of the mediated regression analysis of Hypothesis 5, all of the subjective knowledge, purchase knowledge, product knowledge and use knowledge after purchase had an impact on purchase intention, partially mediated by attitude, and brand image, too, had an impact on purchase intention, partially mediated by attitude.
