This paper presents the robot program for propeller grinding. A robot manipulator is constructed by combining a parallel and a serial mechanism to increase high sitffness as well as workspace. The robot program involves inverse/direct kinematics, velocity mapping, Jacobian, and etc. They are cerived in efficient formulations and implemented in a real time control. A velocity control is used to measure the hight of a propeller blade with a touch probe and a position control is performed to grind the surface of the blade.

고유진동수와 감쇠비는 지진이나 바람과 같은 동적 횡하중에 대해 구조물의 응답을 결정하는 주요한 특성이다. 본 연구는 지진하중에 대하여 목표응답 수준을 만족하는 구조물의 고유진동수와 감쇠비를 지정하고, 이 값을 실현하는 점탄성 감쇠기 파라미터의 처적분포를 구하는 설계방법을 제안한다. 여기서 지정할 고유진동수와 감쇠비는 목표응답 수준을 만족하는 여러 조합 중 설계조건과 원래 건물의 특성에 따라 결정될 수 있다. 제안한 설계방법은 점탄성 감쇠기의 감성 파라미터를 고유값의 기울기 정보를 바탕으로 분포시키므로 최적 위치와 크기에 대한 정보를 동시에 제공한다. 예제로서 평면 10층 전단 건물을 대상으로 최적설계를 수행하여 지정된 고유값을 실현하는 파라미터의 최적분포를 구하고 이를 통해 제안한 최적 설계의 특성을 확인하였다. 또한 더 나아가 3차원 일방향 비대칭 전단전물에 제안된 최적설계를 수행하여 그에 대한 적용가능성을 확인하였다.

기존 가로등 유지보수시스템을 위한 모니터링 기술은 크게 CDMA양방향통신, Zigbee 혹은 USN을 이용하는 방법, 분전함 단위로 PLC를 이용하는 방법 등이 있다. 그러나 CDMA방식은 높은 회선사용료를 지불해야 하며, Zigbee 혹은 USN을 이용한다. 본 연구를 통해 그룹단위로 감성조명과 고장진단을 위한 LED 가로등 고장진단 시스템을 설계 구축하고, 핵심 컴포넌트인 BSD(Brightness Sensor Device)를 설계 및 구현하였으며, 실험을 통해 효용성을 검증하였다.

Today, the city greatly increase the interest in the night, increasing the importance of building and landscape lighting is a trend. Landscape lighting and a combination of factors, especially the media has been expanding in the domestic media facade. The facade of the building for the implementation of the screen to install the LED, or are projecting the image through the projector. The facade of this study present a paradigm shift in traditional media based on interactive and works by combining the artistry of the item type, art, colors, patterns, and interactions were drawn into 5 main topics. This section of the 83 kinds of domestic. Other media facade sample was classified. Categorized by 5 types of lighting techniques, lighting system, manner of expression, changing the way lighting design elements were based. Thus, the current trend changes, depending on the technical value and artistic value of the applied media facade lighting design should be applied to identify the elements and the combination of media facades and IT skills beyond simply directing programmed to communicate interactively with various designs Must be for you.

Analysis of narrative texts has been regarded as academically and practically important, and has been made from various perspectives and methods. In this paper, the computational narrative analysis methodology from the perspective of information processing was examined. From the point of view of information processing, the creation and acceptance of narrative is a bidirectional coding process mediated by narrative text, and narrative text can be said to be a multi-layered structured code. In this paper, four methodologies that share this point of view - character network analysis, text mining and sentiment analysis, continuity analysis of event composition, and knowledge analysis of narrative agents - were examined together with cases. Through this, the mechanism and possibility of computational methodology in narrative analysis were confirmed. In conclusion, the significance and side effects of computational narrative analysis were examined, and the necessity of designing a human-computer collaboration model based on the consilience of the humanities and science/technology was discussed. Based on this model, it was argued that aesthetically creative, ethically good, politically progressive, and cognitively sophisticated narratives could be made more effectively.

The purpose of this research is showing an appropriate way of maximizing customer service and establishing VOC system by analyzing different voices from complaining customers as well as loyal customers. This research is also aimed at figuring out how companies can implement effective service marketing methods in the field complying with customers' needs and how they can survive in the competition. The range of research is confined to 5 marketing companies and their web-sites on which customers can get logged and directly post their claims. These web-sites showed how those 5 companies cope with customer claims. A questionnaire research was made in A's store to evaluate customer satisfaction. These are conclusions drawn by this research. First, prompt reactions of sincerity to customers' claims contribute to building favorable corporate images. Second, the preference to VOC channels varies with age and sex. Marketers should implement respectively different channels for customers under age 30 and those over age 40. Women have a tendency to prefer instant phone conversations and want to have their claims well listened to. Third, a series of shift in customer trend drives companies into establishing their own interactive VOC systems based on customers' preferences. Customer-oriented management has become a key factor for survival in recent intensely competitive market situation, as the web-based e-commerce market has been rapidly growing accompanied with a dramatic advance of network marketing methods. This research suggests some practical methods to establish a customer-oriented VOC system that can be easily adopted in the field.

By using smartphones more generally, people's lives become more convenient. However, many people complain of stress caused by the use of smartphones, further, the tendencies to reject it are appearing. In this paper, new conceptual word, antismart-resistance consciousness gained by experience before and after introduction of smart devices - is newly proposed as a research variable. In addition, we have studied to identify the relationship affecting continuous use of smartphones with technostress and antismart. To achieve this, a research model and hypotheses were presented and verified by using questionnaires data. The result showed that users who actively embrace innovative technologies were highly tolerant of technostress, whereas knowledge or experience of IT trends did not affect technostress or antismart tendencies.

This study analysed about to feasiblity of metaverse what it can be grantify the need of the current generation even though webtoon have limited environment and fixed story and if it possible, whether to some extent it possible. This study have direction it was set the needs of users centrically and was purposed to found a model for invigoration of webtoon market in metaverse to come. For this study, direction of development of metaverse, precedent study about metaverse and than analyzed it about based on grafted cases of metaverse and webtoon.

This research investigated the cross-modal correspondence between the turbidity and taste of beverages. For an empirical study, we employed two types of achromatic beverages: rice wine and a soft drink. The turbidity of each drink varied between 0.0625~32 g/L, and 0.0078~4 g/L, respectively, and the stimuli were prepared in ten levels according to cognitive turbidity. In the study, participants (N=35) rated each drink stimulus using a 3-point Likert scale with regard to five basic tastes: sweet, salty, bitter, sour, and preferred. In addition, six specific tastes were included that deliberately describe rice wine and the soft drink. Three were yeasty, alcoholic, and astringent for the rice wine, and the other three were creamy, bubbly, and syrupy for the soft drink. Based on participants' assessments, the turbidity of rice wine is highly positively correlated with all five basic tastes. In contrast, the turbidity of the soft drink was positively correlated with sour only. Concerning preference, the most preferred turbidity of rice wine was 4.6~20 g/L, which is close to the turbidity of existing products on the market. Furthermore, except for astringent and syrupy, all tastes were influenced by the turbidity, which implies the potential of turbidity as a new visual parameter to communicate the taste experience of beverages.
