The design of injection molded polymeric parts has been done empirically, since it requires profound knowledge about the moldability and causal effects on the properties of the part, which are not available to designers through current CAD systems. An interactive computer-based design system is developed in order to realize the concept of rational design for the productivity and quality of mold making. The knowledge-based CAD system is constructed by adding the knowledge-base module for mold feature synthesis and appropriate CAE programs for mold design analysis in order to provide designers, at the initial design stage, with comprehensive process knowledge for feature synthesis performance analysis and feature-based geometric modeling. A knowledge-based CAD system is a new tool which enables the concurrent design with integrated and balanced design decisions at the initial design stage of injection molding.

The design of delivery system is one of the most important subject in injection molding. Delivery system is a channel to flow the polymer melt from the injection molding machine to the mold cavities and affect quality and productivity of the part. The synthesis of delivery system of injection molding has been done empirically, since it requires profound knowledge about the moldability and causal effects on the properties of the part, which are not available to designers through the current CAD systems. A knowledge-based CAD system is constructed by adding the knowledge module to an existing geometric modeler and contains knowledge to permit non-experts ad well as mold design experts to generate the acceptable geometries of gate and runner for injection molded parts.

The purpose of this study was to investigate the effects of students' prior knowledge on scientific reasoning in solving a pendulum task with a computer simulation. Subjects were 60 Korean students: 27 fifth-grade students from an elementary school and 33 seventh grade students from a middle school located in a city with 300,000 people. This study adapted a pendulum task presented with a computer simulation on which subjects would use a pattern of multivariable causal inferences. The subjects were interviewed individually in a three-phase structured interview by the researcher and three assistants while he/she was investigating the pendulum task. This study showed that most students across grades focused heavily on demonstrating the primacy of their prior knowledge or their current hypothesis. In addition, students' theories that are part of one's prior knowledge have a significant impact on formulating, testing, and revising hypotheses. Therefore, this study supported the notion that students' prior knowledge had a strong effect on students' experimental intent and hypothesis evaluation.

Knowledge is a key resource for organizations to gain and maintain competitive advantage. Therefore, it is important for organizations to motivate employees to share knowledge with each other in order to achieve optimal performance of knowledge resources. Despite the efforts of organizations to share knowledge, knowledge hiding is still prevalent among employees. In this paper, we want to analyze the factors that may cause more general and pervasive knowledge-hiding behavior in organizations through empirical analysis. The results of this study show that, first, the relationship between team cohesion and knowledge hiding has been verified differently depending on the sub-behavior of knowledge hiding : playing dumb, evasive hiding, and rationalized hiding. Team cohesion has been shown to significantly reduce the playing dumb and evasive hiding. On the other hand, it was shown that team cohesion did not have a significant causal relationship with rationalized hiding. Second, the moderating effect of ethical leadership has been statistically significant in terms of team cohesion and relationships with playing dumb and evasive hiding. In other words, the higher the ethical leadership, the stronger the negative relationship between team cohesion and knowledge hiding. Finally, the theoretical and practical implications of this paper and future research directions are discussed.

개념과 범주는 관찰하지 못한 속성을 추론할 수 있는 기반을 제공한다. 무의미 속성을 사용한 범주기반 속성추론 연구들은 범주 및 속성의 유사성이 추론을 설명하는 핵심 요인이라는 것을 제안했다(Rips, 1975; Osherson et al., 1990). 이후 연구들은 사람들의 사전지식이 범주기반 추론에 막대한 영향을 미치며 심지어 유사성 효과가 완전히 사라지는 경우도 있음을 보고했다. 본 연구는 범주 속성들이 사전지식의 한 종류인 인과적 지식에 의해 사슬구조로 연결되었을 때의 범주기반 속성추론을 검증했으며 그 결과를 예측하는 속성추론모형을 제안했다. 참가자들은 네 개의 속성들이 사슬구조를 이루는 인과적 범주를 학습한 뒤 해당 범주의 다양한 범주 예시들의 숨겨진 속성에 대한 추론을 실시했다. 그 결과 인과적으로 직접 연결된 속성뿐만 아니라 다른 속성 노드에 의해 차폐된 속성들도 추론에 영향을 미치는 비독립성이 나타났다(인과적 마코프 조건의 위배). 인과모형이론(Sloman, 2005)에 기반한 속성추론모형을 적용하여 참가자들의 추론을 모델링한 결과 인과적 연결의 직접 효과뿐만 아니라 간접 효과 즉 인과추론의 비독립성도 예측하는 것으로 나타났다. 다만 간접적으로 연결된 속성들은 인과적 거리와 무관하게 참가자들의 추론평정에 동일하게 영향을 미쳤지만 모형은 거리가 멀어짐에 따라 추론에 미치는 영향이 작아짐을 예측했다.

The purpose of this study was to investigate the causal relationship of kindergarteners' alphabet knowledge to their ability to read words, in connection with the features of the Korean alphabet 'Hangul'. A total of 289 children aged four to six from three kindergartens in Busan participated in the study. The main results are as follows. To begin with, the participants showed continuous development in the knowledge of consonant names, vowel sounds, the vowel stroke-adding principle, and the alphabet composition principle. Meanwhile, discontinuous development was found in the knowledge of consonant sounds and the consonant stroke-adding principle, which indicated that kindergartners could show differential speed in various sub-skills of literacy development. The kindergartners' naming of consonants developed before their recall of consonant sounds, and the knowledge of consonant sounds had an effect on the knowledge of vowel sounds. Children had difficulty in treating more complicated letters of the alphabet stroke-adding principle test, and eve syllables of the alphabet composition principle test. Most importantly, the children's alphabet knowledge was strongly related to their ability to read words written in Hangul, as kindergarteners with a greater knowledge of alphabet names, sounds, and principles were shown to read words better.

Objective: The purpose of this study was to analyze the causal relationship between parenting knowledge, parenting stress, and parenting behavior of mothers with infants and to confirm the longitudinal mediating effect of parenting stress in the relationship between parenting knowledge and parenting behavior. Methods: This study used data collected through the Panel Study on Korean Children from 2008 to 2010 and the participants were 1,444 mothers with infants. The data were analyzed through technical statistics, correlations and multivariate potential growth models using SPSS 28.0 and AMOS 26.0. Results: Parenting knowledge and parenting stress of mothers gradually increased, and positive parenting behavior gradually decreased. Having a lot of parenting knowledge reduced mother's parenting stress. Mother's parenting stress reduced positive parenting behavior, and as parenting stress increased, positive parenting behavior decreased significantly. However, the relationship between parenting knowledge and parenting behavior was not significant. In addition, the mediating effect of parenting stress was confirmed in the relationship between parenting knowledge and parenting behavior of mothers. Conclusion/Implications: The results of this study suggest the need to reduce parenting stress and promote positive parenting behavior along with the systematization of parent education programs in order for mothers with infants to acquire parenting knowledge.

An integrated fault diagnosis system for heterogeneous manufacturing environments is developed. This system has a contrast with existing diagnosis systems in the respect that they are mostly for diagnosing faults on individual machines. In addition to the usual (e.g., audio, electrical) diagnostic signals, the characteristics of products from the machines are considered as the unifying diagnostic parameters among heterogeneous machines in the diagnosis. The system is composed of a knowledge representation scheme and a diagnostic query processing mechanism. Its knowledge representation scheme allows the diagnostic knowledges from heterogeneous unit diagnostic systems to be uniformly expressed in terms of the causal relations among relevant data items. It is flexible in the sense that causes for one relation can be effects for another may be reflected on our knowledge representation scheme. The diagnosis mechanism is based on a probabilistic inferencing method. This probablistic diagnosis mechanism provides more general diagnosis than existing ones in that it accommodates multiple causes and takes complication among causes into account. These scheme and mechanism are applied to a typical example to demonstrate how our system works.
