Even though patterns and correspondence serve a fundamental basis of function for elementary students, there has been lack of research in this field. This study explored prior studies to extract the key instructional elements on how to teach patterns and correspondence. This study then analyzed the unit of 'patterns and correspondence' in the mathematics textbooks in terms of four key instructional elements (i.e., relation to real-life contexts, diversity of pattern tasks, exploration for a correspondence relationship, and teaching variables). The results of this study showed that topics dealing with patterns and correspondence were represented with relation to real-life contexts but diversity of pattern tasks and exploration for a correspondence relationship were needed to be further considered in the textbooks. Another noticeable result was that teaching variables was not explicitly addressed in the textbooks. Based on these results, this study provides textbook writers with implications on what to further consider in dealing with patterns and correspondence.

At the recent 19th General Election, Korean papers waged a surrogate war for the parties they share ideology with. All the conventional practices remained the same - the horse race-like presentations, furthering of confrontations, disregarding policy issues, allocating larger space for commentaries and negative issues, and etc. On top of these, papers began to focus on generational conflicts and individuals at the center of widespread attention and controversies, as a new trend. Photo images are largely used in the commentaries and articles dealing with confrontational or controversial situations. Of course, while the visual images seem to reinforce the emotional appeal of the messages papers try to get across, the potential problems need be noticed that could rise when irrelevant images are used.

The purpose of this study is to analyze the science history materials presented in middle school 'Science' textbook according to the 2015 revised curriculum. The subjects of this study were 14 middle school 'Science' textbooks. The analysis used the three-dimensional framework. The results of analysis show that the number of science history materials presented in textbooks tends to increase as the grade goes up. It was also found that science history materials were presented in a specific unit for each grade. The three-dimensional analysis of science history materials showed that conceptual-fundamental-discovery/device types were most commonly presented in all grades. At the instruction context level, the conceptual context was the most common, and the basic role was the main at the role level. The discovery/device type was the most common type of presentation. The results of the study show that the science history materials presented in science textbooks were concentrated in some areas. Also, the instruction context and role were concentrated in some factors in terms. This suggests that various science history materials need to be developed in the future. It is also necessary to explore concrete methods to ensure that science history materials presented in textbooks can be used in various roles in different contexts.

Recently, the sound design of the electric vehicle has emerged as one of the new research objects. This study was conducted to explore and examine major values of interior driving sound of the electric vehicle from the perspective of user experience. An exploratory study based on the ground theory extracted contextual information and quietness as independent variables, and then we analyzed the main and interaction effects of those two variables on the usefulness, emotion, and satisfaction through a $2{\times}2$ factorial experimental design. The experimental study demonstrated that the effect on the user experience of electric vehicle can be conditioned by the combination of contextual information sound and quietness. Based on the results of this study, we suggested future research agendas for the optimization of user needs which reflect individual preference of interior driving sound values.

The possibility of metaverse system to be a catalyst for hyper-connected society will be dependent on the speed of connected technological development and its social utilization in the same manner as AI technology. Putting these technical realization processes in brackets, this paper focus on some philosophical-political issues in connection with cognitive-ecological changes in the future cinema which will be influenced by the complexive techno-socio couples of accelerated development of metaverse system. Generally speaking, essence of metaverse system seems to be the degree of immersion by technical accuracy, but is not true. In perspective of cognitive-ecology, flow degree of a picture or photograph is relied not on 'accuracy of representation' but on its message's contextual link-up. In this aspect, real potentiality of metaverse system shall be understood in the context of cognitive-ecological changes of human brain's multi-intelligence networking abilities(intersection of augmentation-simulation and outside-inside) which will be activated in the new structure of natural-social-technological coupling of metaverse system. These cognitive-ecological potentialities have been partially actualized in the cinematic process of tripod mimesis for the longest time, [real contradiction/conflicts (Mimesis-1) -->fictional solutions of cinema (Mimesis-2) --> selective interpretation of spectator's wish fulfillment (Mimesis-3) --> real change (Mimesis-1')]. Therefore metaverse's real potentiality must be considered to be dependent on the possibility of deepening and extending of cinematic circulation between real seperation/problems and ideal connection/solutions. In this context, advanced metaverse system can be compared as a modern technical version of ideal circulation of physics and metaphysics

This study aims to identify work conflicts in Korean socio-cultural context by applying grounded theory. Survey has been conducted through in-depth interviews with 11 different employees from various occupational categories. Data collected from the survey were then analyzed based on the grounded theory of Strauss and Corbin (1998), thus resulted in a paradigm model consisting of 31 categories, 63 subcategories, and 100 concepts by open coding. Axial coding was then conducted and the results were as follows. The causal condition was the 'character of an opponent'. Contextual conditions which affect the causal condition were 'situational characteristics', 'character of an opponent', 'character of oneself', and their 'mutuality'. 'Negative feeling' was the central phenomena of work conflict and action/interaction strategies were verified to be 'avoidance', 'expression', 'effort toward solving problems' and 'increasing conflict'. Intervening conditions were 'interrelation', 'intervention', and 'group/task characteristics'. The consequences were organized as 'conflict continuance', 'personnel change' and 'positive effect'. Through selective coding, 'managing with the conflict' was derived as core-category and three different types of management were classified. Ultimately, this study shows how employees work in Korea experience the work conflicts and what kinds of socio-cultural factors have influence on the work conflicts, which can supplement previous inadequate empirical research. Also, this study can provide implications and suggestions as a fundamental integrated model for the future empirical research on work conflicts.

Recently, with the development of computing technology and the improvement of the cloud environment, deep learning technology has developed, and attempts to apply deep learning to various fields are increasing. A typical example is anomaly detection, which is a technique for identifying values or patterns that deviate from normal data. Among the representative types of anomaly detection, it is very difficult to detect a contextual anomaly that requires understanding of the overall situation. In general, detection of anomalies in image data is performed using a pre-trained model trained on large data. However, since this pre-trained model was created by focusing on object classification of images, there is a limit to be applied to anomaly detection that needs to understand complex situations created by various objects. Therefore, in this study, we newly propose a two-step pre-trained model for detecting abnormal situation. Our methodology performs additional learning from image captioning to understand not only mere objects but also the complicated situation created by them. Specifically, the proposed methodology transfers knowledge of the pre-trained model that has learned object classification with ImageNet data to the image captioning model, and uses the caption that describes the situation represented by the image. Afterwards, the weight obtained by learning the situational characteristics through images and captions is extracted and fine-tuning is performed to generate an anomaly detection model. To evaluate the performance of the proposed methodology, an anomaly detection experiment was performed on 400 situational images and the experimental results showed that the proposed methodology was superior in terms of anomaly detection accuracy and F1-score compared to the existing traditional pre-trained model.

The aim of this study is to investigate the method to enhance user cognition for "STM information(Short-term Memorable Information)" that is relatively accessible to information in a short period of time in information design types. What stands out from this study is the design attributes and expression method of information in a broad perspective. By 4 visualization attributes of function variable; 'Operations', 'Events', 'Methods' and 'Use cases', STM information should be satisfied by the attribute of 'Understandable' and 'Accessibility' from the point of view of visual representation and by the attribute of 'Errorless' and 'Timeliness' from the point of view of user operation. As the expression method of each perspectives, I suggested "Attribution theory", "Cognitive model", "Maximization of Proactivity", "Minimization of surplus information" and "Using dual-code" in the point of view of visual representation, and "Context effect", "Using memory code" and "Two methods of information scanning" in the point of view of user operation. I assured that above-mentioned methods are efficient and cognitive pattern of user for STM information is found out by survey and interview.

아동의 언어습득 과정에서의 모방은 흔히 볼 수 있는 현상이지만 한편 인간의 독특하고 신기한 일면이기도 하다. 이 모방에 관하여 그동안 많은 연구들이 되어왔으나 그 중요성이나 역할에 대한 연구들의 결론이 모두 일치하는 것은 아니다. 본 논문에서는 이 모방현상에 대한 그 동안의 연구들을 이론별로 분류해 보고 각 이론들이 모방의 역할을 밝히기 위하여 사용해 온 연구방법, 절차들을 분석해 보았다. 행동주의와 사회학습이론에서는 언어습득에서의 모방의 역할을 특히 강조하고 있으며 이 모방의 효과를 입증하기 위하여 다른 어떤 이론보다도 훨씬 조직적인 실험연구를 해 왔다. 이와는 대조적으로, 언어 심리학적 접근에서는 언어습득에서의 생득성과 창의성을 강조하므로 모방의 역할은 중시하지 않으며, 모방의 정의를 엄격하게 규정하고 자연적인 관찰 중심의 연구를 주로 하여 언어습득에서의 모방의 역할이 미비하다는 결론을 내리고 있다. Piaget 중심의 인지발달적 접근에서는 모방을 인간의 전체 발달의 한 측면으로 보아 모방은 인지발달과 함께 점진적으로 발달되는 것으로 설명하고 있다. 특히 언어발달에서의 지연모방의 중요성을 강조하고 있으며, 대부분의 연구는 자연적인 관찰연구를 통하여 모방의 발달과정을 밝히고 있다. 언어발달에서의 모방의 역할에 대한 지금까지의 일치하지 않는 연구 결과들은 각각의 이론들이 나름대로 달리 모방을 정의하고, 언어의 다른 측면들을 다루어 왔기 때문으로 밝혀 졌다. 앞으로 언어발달이 아동의 발달 전체의 맥락 속에서 연구되어지고, 언어습득과정에서 보이는 아동들의 개인차까지도 고려되어지는 포괄적인 연구가 이루어지면 모방의 역할도 좀더 명백하고 일관성 있게 밝혀지리라 본다.
