The affective primacy hypothesis of Murphy와 Zajonc(1983) was replicated in this study. The results of experiment 1 and 2 expanded the affective priming effect by facial valence as well as affective events on object rating. Experiment 3 explored the affective priming effect of schizophrenics at the supraliminal level and their results compared with those of normal subjects. For normal subjects the effect of affective priming was found only at the subliminal level but schizophrenics showed the assimilation effects by affective priming even at the supraliminal level. Finally. principles of affective processing were discussed.

The PCK of teachers about informatics subject, which is viewed as one of required subjects in today's information society, is linked to what and how to teach, and that is very significant in terms of academic education. However, there are currently no efforts to develop items geared toward evaluating the PCK of teachers about informatics subject or to make a factor analysis of those items, though the importance of that subject in information society has been discussed. The purpose of this study was to develop and validate an instrument to size up the PCK of preservice elementary teachers about informatics subject. The finalized instrument consisted of 39 items regarding five factors that involved knowledge of curriculum, knowledge of expression, knowledge of content, knowledge of evaluation and knowledge of teaching methods.

Information center represents an important source which seems very well suited for knowledge management investigation. Information center is knowledge intensive and the use of advanced technology may transform the knowledge of business processes for delivering an unique capabilities in an organization. To exam knowledge management, organization culture, importance of knowledge, and support of information technology were identified as potential predictors of knowledge management support in information center. Three hypotheses have been tested with 43 database management specialist surveys. This study presents that the level of information sharing and knowledge exchange is significantly influenced by the extent support of information technology.

Teachers' mathematical knowledge for teaching (MKT) strongly influence student achievement (Hill, Rowan, & Ball, 2005). However, there is generally no record that shows the levels of teachers' MKT in schools and districts. Because of the limited resources, schools and districts need some criteria to decide how to distribute their resources to help teachers improve MKT. This study explores what factors in teachers' backgrounds are related to their levels of MKT. This article examines the relationships between the MKT of 336 elementary teachers and their demographic, educational, and teaching backgrounds. To measure MKT, I used a series of multiple-choice problems. The number of years teaching mathematics is not critical to these measures. Implications are discussed with regard to policy for mathematics teacher education.

While software globalization is becoming more important, little research has been undertaken into what is meant by globalization and the degree of globalization capability in the Korean software industry. A survey study was conducted among software engineering professionals, gathering the data from 31 IT companies across 7 large-scale projects in Korea. The results indicate that the evaluation score for globalization capability is 2.51 out of 5 points, which is the lowest compared to other areas of software engineering such as team capability (2.88), process and tool supports (2.96), project management (2.97) and development (3.64). We also discuss how to introduce software globalization technologies in Korea based on the successful experiences of leading global IT companies.

This study examined the effect of housing cost burden on the intention of moving into public rental housing. For the empirical analysis, I used the 2019 Korea Housing Survey and divided the households based on housing tenure and income level and they are as follows: homeowners, renters and low income, middle income and above. As analysis method, the binomial logit model is used and the empirical analysis shows that the burden of housing costs was increased the intention of moving into public rental housing even in homeowners and households with middle income or higher.

Previous research on learning and memory has focused on how they are constructed through past experiences. Recent studies, however, have shed light on that such cognitive processes are in service of higher goals of maximizing future rewards. This review paper aims to introduce and discuss a related line of research. First, this paper introduces researches that show goal-directed model-based reinforcement learning, in which agents choose a behavior that does not necessarily bring immediate rewards but will allow future rewards, based on generalization and analogical extrapolation. It also reviews studies on neural substrates of goal-directed learning, and discusses that cognitive process implicated in striatal dopaminergic signals can also influence memory. Especially, memory is not a merely passive process of storing and retrieving past experiences homogeneously, but rather results of a decision-making process to serve higher goals. The body of research suggests that information on future rewards can have influence on current cognitive processing in a retrospective manner.

How to obtain the financial resources has not been sufficiently addressed, although the unification of Korea incurs enormous cost. This study explains what tax payers of Korea think with regard to the unification tax which is a contradictory issue as a financial resource. The authors analyzed demographic factors, an initial attitude to unification and tax system, and the degree of knowledge as independent variables affecting the intention to pay the unification tax. Furthermore, through the prospect theory, the authors found out how the attitudes of tax payers change by providing them with different messages according to whether they support or oppose the unification tax. The results showed that a group who are male, a group who are old, and a group with high income tend to support the unification and the unification tax more than others. And the results presents that a group who has more interests in both the unification and the unification tax and a group who has more knowledge about the unification and the tax system have more willingness to pay the unification tax than others. In addition, with regard to the persuasive effect of distinct message types, a message which conceals the cost of attitude change was demonstrated to be more effective than a message which emphasizes the benefit.

In this paper, we analyze and discuss the trend of the probability and statistics problems that have been made in the public secondary school teacher employment exam for mathematics teachers. In order to properly teach the national mathematics curriculum in 2015 in terms of content and function, we investigate the probability and statistics contents that a mathematics teachers should know. We also analyze the contents and trends of the items that have been submitted for 15 years in public secondary school teacher employment exam, and discuss the contents, scope, level and direction of the future contents. In conclusion, considering the significance of the Big Data in the 4th industrial revolution, the problems of statistical thinking of data and probability, exploratory data analysis, sample survey, and statistical inference are needed more.

Even though statistics is considered as one of the areas of mathematical science in the school curriculum, it has been well documented that statistics has distinct features compared to mathematics. However, there is little empirical educational research showing distinct features of statistics, especially research into the understanding of statistical concepts which are different from other areas in school mathematics. In addition, there is little discussion of a relationship between the ability of mathematical thinking and the ability of understanding statistical concepts. This study extracted some important concepts which consist of the fundamental statistical reasoning and investigated how mathematically high achieving students understood these concepts. As a result, there were both kinds of concepts that mathematically high achieving students developed well or not. There is a weak correlation between mathematical ability and the level of understanding statistical concepts.
