지식경영의 기본적인 목적은 조직 구성원간에 효과적으로 지식을 공유 하도록 하는 것이다. 지식 경영에 관련된 많은 연구들은 지식 공유가 필요한 상황 및 지식 공유를 촉진시키는 조직 환경에 집중해왔다. 그러나 조직에 속한 개인들이 누구와 어떻게 지식을 공유하는 것이 가장 효과적인지에 대해서는 충분한 연구가 이루어지지 않았다. 본 연구의 첫 번째 주제는 지식 전달자와 지식 수용자간에 지식을 주고 받을 때 전달되는 지식 속성의 질을 결정하는 요인을 규명하는 것이다. 특히 본 연구는 프로젝트를 수행하는 개인간의 지식 공유에 초점을 맞추고 있다. 본 연구의 두 번째 주제는 지식 속성의 구성과 지식 속성이 지식 효용 및 업무 결과의 물리적 그리고 심리적 측면에 어떠한 영향을 미치는 지를 규명하는 것이다. 본 연구는 기존 연구와 달리 지식 속성의 질을 지식 공유의 성공 여부를 결정짓는 중요 요소로 인지한다.

일반적으로 어떤 제품을 평가할 때 제품이 가지는 기능적 속성 이외에 감성에 의해 제품을 평가하게 된다. 그 제품의 기능과 더불어 제품이 보이는 감각적 속성과 그 제품에 대한 추상적이고 개념적이며 일반적인 인지적 틀을 가지고 그 제품을 지각하게 되는 것이다. 제품을 개발하는 과정에서 민족 또는 국가 간의 다양한 생활문화에 반영된 감성이미지를 구체화할 수 없다면 디자이너가 만들어내는 제품이란 기능적 한계에 제한되기 마련이다 즉, 어떠한 제품의 개발에 앞서 우선적으로 고려되어야 할 문제 중 하나가 바로 사용자들이 요구하는 감성이 무엇인지를 아는 것이다.

데이비슨에서부터 시작됐다고 해도 과언이 아닌 것으로 보이는 정신적 속성들의 인과적 힘과 관련된 논의 - 정신인과의 문제를 해결하기 위해서 설정하는 - 는 그가 주장한 이론이 맞이하게 되는 심각한 문제에 해결책을 제시하고자 하는 많은 책학자들의 관심을 불러일으킨다. 그 중의 하나인 포돌도 결국 데이비슨이 주장한 세 가지의 원리들 중에서 중요한 한가지 원리, 즉 정신적인 것들의 무법칙성의 원리, 를 거절하면서 자신의 정신인과 이론을 발전시키고자 한다. 즉 정신적 속성들과 물리적 속성들을 연결시키는 "참 인과의 법칙으로서 다른 것들이 같다면의 법칙"을 정신인과의 현상을 설명하는 그의 설명적 모델로 제시하면서 데이비슨의 문제를 해결하려고 시도한다. 그러나 그가 스케치하는 그런 그림은 인과적 배제의 원리를 명백하게 위반하는 것이다. 설상가상으로 이러한 문제를 벗어나기 위해서 그가 의지하는 수반의 개념도 그 효력은 충분하게 강하지 못한 것으로 드러난다. 이것이 틀리지 않다면 여기서 어떤 딜레마가 일어난다. 만약 정신적 속성들이 아직까지 인과적으로 효력을 가지고 있다면 명백하게 물리적 세계의 인과적 폐쇄의 원리의 위반이 일어난다. 만약 정신적 속성들이 인과적 효력을 가지고 있지 않다면 우리는 여기서 명백히 부수현상론을 보게 된다.

The purpose of this study is to search effective assessments methods by using the Fusion model of Cognitive diagnosis theory. Attributes are skills or cognitive processes that are required to perform correctly on a particular item. After test items were developed, item's attributes were decided and Q-matrix about item's attributes was made. After testing, the result was analyzed according to gender and achievement level. The results of the analysis showed that students mastered 'Interpreting data' best, and 'synthesizing' worst among the five attributes. Female students showed higher ability than male students in 'recalling.' Students of high achievement level mastered more scientific attributes than students of low achievement level. Conventional assessments only provided a single summary score but Cognitive diagnosis modeling provided useful information by estimating individual knowledge states by assessing whether an examinee has mastered specific attributes measured by the science test. The skill profiles can offer a skill level of strong, weak, or mixed for each student for each skill. Therefore, the skill profiles will provide useful diagnostic information in addition to single overall scores.

This study analyzed Korean students' affective characteristics in mathematical learning according to school and sex by Factor Analysis and Cognitive Diagnosis Theory. In numerical affective achievements by Factor Analysis, there are mean differences between schools, i.e. elementary school and secondary school. And there are sexual differences within schools and boys show more positive achievement than girls. By Cognitive Diagnosis Theory, I investigated 6 affective attributes' proportions that students achieved according to school and sex. Middle school students' proportion is highest in self-control and anxiety and the attribute that students achieved most in all school is cognizing mathematical value. Boys show higher proportion in self directivity, interest and confidence than girls, but girls show higher proportion in anxiety than boys. In personal profiles, the proportion of students who achieved 5 attributes except anxiety is highest.

The cognition of an intrinsic attribute play an important role in the process of theoretical generalization. It is the aim of this paper to study how the theoretical generalization is made. First of all, we suggest the What-if-only-strategy(WIOS) which is the strategy helping the cognition of an intrinsic attribute. And we propose the process of the theoretical generalization that go on the cognitive stage, WIOS stage, conjecture stage, justification stage and insight into an intrinsic attribute in order. We propose the process of generalization adding the concrete process cognizing an intrinsic attribute to the existing process of generalization. And we applied the proposed process of generalization to two mathematical theorem which is being managed in middle school. We got a conclusion that the what-if-only strategy is an useful method of generalization for the proposition. We hope that the what-if-only strategy is helpful for both teaching and learning the mathematical generalization.

In landscape studies, the concept of naturalness was vast in its categories from physical space to cognitive systems, making it difficult to define terms at once. Therefore, this study summarized the concept and evaluation attributes of 'naturalness' used in the literature through systematic review (SR), and identified the scope of individual attributes that constitute the meaning of naturalness. In addition, the individual attributes classified in previous studies were identified as the meaning chain, one of the cognitive linguistic research methods, and applied to papers targeting naturalness among domestic landscape studies to organize a polysemous meaning system. Meaning chain is a suitable method for grasping words whose meaning expands in a chain due to family resemblance around prototypical meaning, and the dimension is classified according to the classification of naturalness evaluation items and a multi-semantic chain system of naturalness concepts discussed in domestic academia. The results of the study are as follows. First, the attributes of naturalness extracted through foreign landscape literature were classified into four areas: nature perceived as wilderness, nature as non-artificiality, nature as visual landscape, and nature as experience, and 13 detailed attributes. Second, these detailed attributes are generally consistent with domestic landscape studies, but their specific cases were different, and a Korean context was presented in perception of time accumulation, also they suggested that there may be a mutual conflict between naturalness attributes.

The study of classifying gamer types or analyzing the characteristics of gamers is a field of interest for data analysis researchers. From the past to the present, much research has been done on gamer categorization and gamer analysis. However, most studies use surveys or bio-signals, which is not practical because it is difficult to obtain large amounts of data. Even if the game log is used, it is difficult to analyze the psychology of the gamer because the gamer is categorized and analyzed by extracting only statistical values. However, if we can extract the cognitive psychology information of the gamer from the basic game log, we can analyze the gamer more intuitively and easily. In this paper, we extracted eight cognitive psychological features representing the behavior and psychological information of the gamer using Crazy Dragon's game log, which is a mobile Role-Playing-Game (RPG). In addition, we classified gamers based upon cognitive psychological features and analyzed them using eight cognitive psychological features. As a result, most gamers were highly correlated with one or two types.

The purpose of this study was to confirm that the property generalization to social categories with low coherence is stronger when stress due to COVID-19 is perceived as high, compared to when stress is perceived as low. To this end, this study selected categories with high coherence(nun, soldier, flight attendant) and categories with low coherence(wedding planner, interpreter, florist), and recruited 336 participants to perform a category-based inductive generalization task(inferring how many properties repeatedly observed by some category members would appear across all category members), and measured their perceived COVID-19 stress. As a result, this study showed that when the cohesion of social categories is high, the effect of property generalization is stronger than when it is low, and the effect of property generalization is stronger in those who perceive stress due to Corona 19 higher than those who perceive it as low. In addition, this study confirmed that people who perceive COVID-19 stress strongly tend to generalize strongly to properties that are repeatedly observed in the low coherence category. This study is important in that it shows that there is a cognitive mechanism that is at the root of the phenomenon that stereotypes and prejudices deepen and discriminatory behaviors increase after the outbreak of COVID-19, such as COVID-19 stress and the resulting increase in attribute generalization tendency.
