The frame element is commonly used for construction stage analysis PSC bridges. However, the frame element does not show sufficient information in the curved PSC box bridges. For the case of curved PSC bridges, the deformations in the inner and outer web are different. In this case, the different jacking forces are required in the inner and outer webs. And it is impossible to calculate different jacking forces in the inner and outer webs if we use the frame element for construction stage analysis. In order to overcome this problem, the use of shell element is essential for a three-dimensional construction stage analysis of PSC bridges. In the following, the formulation of an assumed strain shell element and its application of PSC box girder bridge analysis are presented.

As a smallest unit of the game story, quest needs to be analyzed in terms of structure in order to study quest storytelling. This thesis introduces structuralist theory of narrative function of folk-tale by Propp to determine the structure of the quest. Propp proposed immutable elements of the characters as 31 kinds of Folk-tale functions. I analyzed assigning quests in MMORPG. As a result, 13 essential functions of the Quest, and 5 add-ons were drawn and the order among functions was figured out. Most quests in MMORPG followed the order of the essential functions and optional add-ons and showed a repeating pattern. The essential and optional functions and its order can be utilized to arrange appropriate element for quest storytelling and to strengthen and lead the various ways of the quest storytelling.

There are several way to classify the furniture. The furniture can be classified into use, style, and function, but if the furniture is classified into the way of production, it can be the industrial furniture and the studio furniture. Especially, technology and function of the furniture are important elements in industrial furniture. However, it could be considered artists' character and concept as more important elements in the studio furniture. The studio furniture had come out one of the historical movement in American furniture field after the World War II. This case to apply found objects began to increase after the 1970s. Using objects In furniture design field had built up sprightly after end of 1950s. This expression could be the statement of new expression that essential properties of matter in objects is removed. I try to suggest original and interesting furniture design to apply found objects in this thesis. Especially, I use the Korean traditional objects for the furniture and try to make their essential function to be changed. Also, I focus on furniture design to have formative element in their shapes.

In the 21st-century postmodernism era, which represents diversity and relativity, one of the most essential elements in the field of education is to strengthen individual human values. Accordingly, we must focus on developing capacity in order to adapt to change. It is clear that the medical field maximizes the need for new judgments to solve life-related problems constantly, and this problem-solving capacity is an essential skill for a physician. Problem-solving capacity can be achieved simultaneously with creativity to apply them in an appropriate manner based on standardized expertise and well-trained skills. Creativity is also a key element that medical education is currently pursuing. Many studies on creativity have resulted in confusion and misunderstandings on the concept of creativity due to similar terms and varied definitions, such as creation, innovation, etc. In this study, we attempt to identify the importance of creativity in medical education by comparing and organizing concepts related to creative capacity.

Structural strengthening of reinforced concrete (RC) beams is becoming essential to meet the up-gradation of existing structures due to the infrastructure development. Strengthening is also essential for damaged structural element due to the adverse environmental condition and other distressing factors. This article reviews the state of the field on repair, retrofitting and rehabilitation techniques for the strengthening of RC beams. Strengthening of RC beams using various promising techniques such as externally bonded steel plates, concrete jacketing, fibre reinforced laminates or sheets, external prestressing/external bar reinforcement technique and ultra-high performance concrete overlay have been extensively investigated for the past four decades. The primary objective of this article is to discuss investigations on various strengthening techniques over the years. Various parameters that have been discussed include the flexural capacity, shear strength, failure modes of various strengthening techniques and advances in techniques over the years. Firstly, background information on strengthening, including repair, retrofitting, and rehabilitation of RC beams is provided.

Technology for emotion recognition is an essential part of human personality analysis. To define human personality characteristics, the existing method used the survey method. However, there are many cases where communication cannot make without considering emotions. Hence, emotional recognition technology is an essential element for communication but has also been adopted in many other fields. A person's emotions are revealed in various ways, typically including facial, speech, and biometric responses. Therefore, various methods can recognize emotions, e.g., images, voice signals, and physiological signals. Physiological signals are measured with biological sensors and analyzed to identify emotions. This study employed two sensor types. First, the existing method, the binary arousal-valence method, was subdivided into four levels to classify emotions in more detail. Then, based on the current techniques classified as High/Low, the model was further subdivided into multi-levels. Finally, signal characteristics were extracted using a 1-D Convolution Neural Network (CNN) and classified sixteen feelings. Although CNN was used to learn images in 2D, sensor data in 1D was used as the input in this paper. Finally, the proposed emotional recognition system was evaluated by measuring actual sensors.
