  • Imwongyeongjeji, Administration of Our Daily Life in Woods and Fields, is a sort of encyclopedia compiled by Seo, Yoo Goo in Joseon Dynasty in the 19th century. This voluminous work is made up of 16 chapters with various references including many articles dealing with architecture. The chapter Seomyongji covering the daily necessities contains a number of methods and materials of building construction. The distinctive feature of these articles is that they are mostly from Joseon's books. It is not similar to other chapters which are made of quotations from Chinese books. Especially, he quoted many of articles about architecture from his own work Geumhwagyeongdokgi, Record of Plowing and Reading in Geumhwa. In addition, He selected only empirical knowledge, put it in the book, and commented on it in his judgment. These articles provide valuable information on architectural knowledge in late Joseon period.

  • Fuzzy control has been researched for application of industrial processes which have no accurate mathematical model and could not controlled by conventional methods because of a lack of quantitative input-output data. Intelligent control approach based on fuzzy logic could directly reflex human thinking and natural language to controller comparing with conventional methods. In this paper, fuzzy controller is implemented to acquire operator's knowledge. The tested system is constructed for sending a ball to the goal position using wind from two DC motors in the path. This system contains non-linearity and uncertainty because of the characteristic of aerodynamics inside the path. Ball position is measured by a vision camera. The system used in this experiment could be hardly modeled by mathematic methods and could not be easily controlled by linear control manners. The controller, in this paper is designed based on the input-output data and experimental knowledge obtained by trials.

  • This paper investigates the effects of firms' foreign market focus on the optimistic bias of analysts' earnings forecasts. Based on a sample of 852 U.S. manufacturing firms between 1994 and 2015, our empirical results suggest that higher growth of foreign market focus is associated with greater levels of analysts' forecast optimism. Drawing on the CEO career horizon and the upper echelon theory literature, we find evidence that CEOs' career horizon and functional background as a CFO moderates the relationship between the growth rate of foreign market focus and analysts' forecast optimism. This shows that while financial analysts perceive internationalization strategies as signaling growth potential, such perception can vary depending on CEOs' individual characteristics.

  • This study aims to examine validity and reliability of the convergence talent measurement. Based on the comprehensive literature review on convergence and convergence talent, we draw 4 main competencies (convergence cognitive, accomplishment, problem solving, and attitude) and 10 critical aspects (creative thinking, critical thinking, cooperation, communication, problem-solving, knowledge accessibility, resource utilization, trust, openness, caring) for building an effective convergence-oriented organization. A validity and reliability test survey were conducted for the analysis to investigate the convergence talent scale. With a data of 151 employees in diverse companies, the results show that the factors demonstrated acceptable levels of validity and reliability. The empirical evidences of our study are 10 key aspects comprising four main dimensions which suggest an available scale for measuring the convergent talent for enhancing convergence-oriented organizations. Our research contributes to the expansion of academic and practical implications on convergence, especially in convergence-oriented organizations.

  • Whether This paper argues that teacher efficacy is an affective affiliate of pedagogical content knowledge (PCK) based on empirical data of a study on the nature and construct of PCK. This study was a collective case study utilizing qualitative research methods. The participants of the study were three high school science teachers in the U.S. Data was collected from multiple sources such as classroom observation, interviews, teachers' written reflection, students' work samples, and researchers' field notes. Data was analyzed using the "In-depth Analysis of Explicit PCK" developed by the author. Data analysis indicated that teacher efficacy played a critical role in developing PCK by facilitating the movement from PCK to the enactment of PCK.

  • In mobile device's user interface, menu organization is very important as well as menu structure because small display of mobile device. Menu items should be organized based on user knowledge structure to design user-centered interface. Traditionally, MDS (Multidimensional Scaling) have been most often used to expose users' perceived organization of menu items. But, information that MDS reveals is just relative spatial location of concepts and not relevant to concepts connection. Unlike MDS, Trajectory Mapping explicitly finds users' cognitive links between perceived concepts. This study proposes a Trajectory Mapping technique for eliciting knowledge structure, especially a set of cognitive pathways linking menu items, from end user. With twelve participants, MDS and Trajectory Mapping were conducted using cellular phone's menu items. And user knowledge structure was analyzed through Visual Concept Map that combination of results of MDS and Trajectory Mapping. After then, menu items were organized according to users' perceived organization. Empirical usability test was also conducted. The results of usability test showed that usability, in terms of task performance time, number of errors, and satisfaction, for newly organized interface was significantly improved compare to original interface. The methodology of this study is expected to be applicable to design a user-centered interface. In other words, Trajectory Mapping technique can be used as a design tool of user interface for imposing user knowledge structure on the interface.

  • The purposes of the present study were to investigate the impact of a apparel brand and an ingredient brand on evaluation(perceived quality, favorable attitude, purchase intention) of apparel products, and to examine the differences in evaluations toward apparel products allied with ingredient brands between groups divided by product knowledge and leisure involvement. The subjects were 235 men and women aged 20 to 40. Two-by-two factorial design were employed. A series of ANOVA were used to determine if significant differences existed in evaluations of apparel products. There was a significant interaction effect of an apparel brand and an ingredient brand on evaluations of apparel products. Empirical results showed that ingredient brands would improve the consumers' perceived quality, favorable attitude and purchase intention toward apparel products. In addition, the results indicated that the respondents that had high leisure involvement and high product knowledge were more likely to evaluate apparel products based on the ingredient brand of the products. However, the respondents that had low leisure involvement and product knowledge were more likely to evaluate apparel products based on the host brand of the products.

  • Cognition and control of grinding trouble occurring during the grinding process are classified into a quantitative knowledge which depends on experimental data and qualitative knowledge which relies on skilful engineers. Grinding operations include a large number of functional parameters, since there are several ways of coping with grinding trouble. One is the qualitative method which depends on empirical knowledge utilizing the skilful experts from the workship, the other is the quantitative method which utilizes the experimental data obtained by a sensor. But, they are all difficult to accomplish from the grinding trouble-shooting system. The reason is that grinding troubles are now easily controlled in the quantitative method, and therefore, trouble-shooting has mainly relied on the knowledge of skilful engineers. Thus, there is an important issue of how a grinding trouble-shooting system can be designed and what knowledge is utilized among the large amount of grinding trouble information. In this paper, basic strategy to develop the grinding database of rule-based model, which is strongly depended upon experience and intuition , is described.

  • Digital knowledge and information goods as experience goods have some unique characteristics such as close to zero reproduction and distribution cost, high price volatility, and low price acceptability. For the reasons, the pricing policies of digital knowledge goods are very difficult and complicate. Also, most consumers of digital goods have experienced cognitive dissonance after buying decision. The purpose of this paper is to investigate what factors affect the price acceptability level and cognitive dissonance of digital knowledge goods buyers. This paper suggest a structural model that was established by the cognitive dissonance theory and S-O-R(Stimulus-Organization-Response) model. The model is consisted of four exogenous variables and three endogenous variables. The empirical test and statistical analysis suggest following results and practical implications. The variables such as product involvement and perception of price fairness that have positive roles to price acceptability have strong influence on the all the three endogenous variables. But the variables such as sale proneness and price mavenism that have negative roles to price acceptability have little influence on the all the three endogenous variables. In the model, the payment intention was very important mediating variable between exogenous variables and two dependent variables, ie. price acceptability and cognitive dissonance. These results imply that the digital knowledge portals must have some differentiated pricing policies to the customers who have price consciousness and price mavenism. Also, they need some special promotions to whom have positive attitude to the value of digital goods.
