This study was examined the characteristics of individual or an organization differences of oriented value and shared value for the employees in the field and management division of clothing enterprises in Korea. The hypothesis of this study are as follows: ＜Hypothesis 1＞ The field employees of clothing enterprise would prefer to have a professional tendency and the management employees would prefer to have the organizational tendency. ＜Hypothesis 2＞ The employees who have organizational tendency would have higher shared standard of organization value than the employees of professional tendency. As a result of the study, the hypothesis 1 has accepted as showing the mean value is high when the field employees have their professional tendencies and the management employees also have their organizational tendencies respectively. The hypothesis 2 has also accepted that the employees who have organizational tendency have higher shared value than the employees of professional tendency.

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.

치의학 연구에서 사용되는 귀무가설 유의성 검정에서 p값을 기준으로 연구의 결과를 평가하는 것은 많은 문제점을 내포하고 있다. 귀무가설이 기각되지 않은 경우에 귀무가설이 옳다는 결론을 내리는 것은 논리적 오류이다. p값에 대한 중대한 오해가 많이 있으며 연구자는 논문을 작성할 때 p값의 해석에 신중해야 한다. 귀무가설검정을 보완하거나 대체할 수 있는 대안으로서, 효과 크기, 신뢰구간, 베이지안 통계 등이 있다.

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.

This study clarified a study of relationship of strategic alliance structure factor, partner selection criteria and performance awareness on the container liners alliance. In order to obtain such objective of study existing literature variables suitable to the container liner were perused and extracted. Research models for research development and three study hypothesis were set out and scope of investigation and samples were chosen. The research hypothesis are followings. H1: The factors of strategic alliance motivation influence the performance awareness. H2: The strategic alliance structure factors influence the performance awareness. H3: The factors of partner selection criteria influence the performance awareness. In the result of the empirical study, the hypothesis 1, hypothesis 2 were supported completely and hypothesis 3 was partially supported.

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.
