  • This paper presents the explorations of hydrothermal vents located in the Marina Arc and Back Arc Basin using the deep-sea ROV Hemire. These explorations were conducted by KRISO and KIOST to demonstrate the capability of Hemire in various applications for deep-sea scientific research. The missions included the following: (1) to search the reported vents, (2) conduct visual inspections, (3) deploy/recover a sediment trap and bait traps, (4) sample sediment/water/rock, (5) measure the magnetic field at the vent site, and (6) acquire a detailed map using multi-beam sonar near the bottom. We installed three HD cameras for precise visual inspection, a high-temperature thermometer, a three-component magnetometer, and a multi-beam sonar to acquire details of the bottom contour or identify vents in the survey area. The explorations were performed in an expedition from March 23 to April 5, 2016, and the missions were successfully completed. This paper discusses the operational process, navigation, and control of Hemire, as well as the exploration results.

  • Textile The purpose of this research is to develop the design for activation of women s hanbok focused on functionality and convenience as well as on keeping the traditional beauty, and then to produce them. As a result of these explorations, I have reached conclusions as follows. first, the transformation of jackets and skirts are mainly limited to partial change in elements of the dress design-width and length of a jacket string and the upper strip on the outside of a jacket, change in width, and granting of symbolic meaning. Second, aesthetic features and formative beauty of traditional hanbok that the harmonization of mainstream colors and highlighting colors and curved silhouettes evoke were mental by products created as our people wished to become friendly to and to harmonize with nature. Third, grounded upon study of lines form and survey on brands, I have developed designs that maintain hanbok’superiority and at the same time incorporate functionality and convenience to fit modern life. I believe that the outcome of these of these explorations will contribute greatly to carrying the traditional beauty of Korean dresses to the maximun, and to developing and popularizing functional and practical living-fitted Korean dresses.

  • Despite its centrality at a pivotal crossroads of both land and sea of East-West trade, communications and travel, the region now known as Southeast Asia provides very few scholarly works situating or featuring it in an international context. Because of this paucity, there is immense scope for exploration. But prior to further explorations, justification is needed to establish that Southeast Asia, as a region, is a subject of interest, relevance, and significance in a global context. Southeast Asia was home to several empires whose reach transcended the region and beyond. Southeast Asia in, and as part of international history as an area of study is therefore justifiable. Moreover, other factors come into play, viz. geography, resources, migration, diffusion of ideas and beliefs from without and accommodation from within, shared experience of imperialism and colonialism, decolonization, and the Cold War, and the collective fate under the Association of Southeast Asian Nations (ASEAN), that further bolster its rationalization as a component of international history. Explorations, on the other hand, examine issues and obstacles that contribute to the paucity of works on Southeast Asia in international history. Furthermore, in contextualizing Southeast Asia in international history, there might appear challenges that need to be identified, confronted, and resolved.

  • Objectives : Perceptual experiences have a causal relationship with reality. If there exists something corresponding to acupoints, there should be perceptual experiences for that something. The purpose of this study is to identify and to analyze the perceptual experiences for acupoints within 『LingShu·BenShu』. Methods : First, we briefly propose a perceptual anatomy in order to describe the perceived human body parts, and their perceived directions and places. Second, we analyze the ways of identifying acupoints in the original text of 『LingShu·BenShu』. Results : From 『LingShu·BenShu』, the procedures of identifying total 64 acupoints were recognized. It was clarified that they are by way of visual and haptic explorations in body regions and partial regions. Conclusions : Perceptual explorations for acupoints follow three major principles: of gradual narrowing down, of determination of direction or place, of relative distance. At the final stages, categories of form and location are encountered by observers. The forms have either concavities or convexities. They are determinate indicators of where acupoints are, while the locations are indetermanate. Haptic forms of acupoints are newly discovered from textual analysis with perceptual anatomy. These properties will shed new light both on study of acupoints and on study of meridians.

  • Human Emotion Recognition is an exciting topic that has been attracting many researchers for a lengthy time. In recent years, there has been an increasing interest in exploiting contextual information on emotion recognition. Some previous explorations in psychology show that emotional perception is impacted by facial expressions, as well as contextual information from the scene, such as human activities, interactions, and body poses. Those explorations initialize a trend in computer vision in exploring the critical role of contexts, by considering them as modalities to infer predicted emotion along with facial expressions. However, the contextual information has not been fully exploited. The scene emotion created by the surrounding environment, can shape how people perceive emotion. Besides, additive fusion in multimodal training fashion is not practical, because the contributions of each modality are not equal to the final prediction. The purpose of this paper was to contribute to this growing area of research, by exploring the effectiveness of the emotional scene gist in the input image, to infer the emotional state of the primary target. The emotional scene gist includes emotion, emotional feelings, and actions or events that directly trigger emotional reactions in the input image. We also present an attention-based fusion network, to combine multimodal features based on their impacts on the target emotional state. We demonstrate the effectiveness of the method, through a significant improvement on the EMOTIC dataset.

  • This paper describes the design and development of a hovering AUV constructed at Cheju National University and analyses the dynamic performance of the vehicle using simulation programs. The main purpose of this AUV is to carry out fundamental tests in its station keeping, attitude control, and desired position tracking. Its configuration is similar to the general ROV appearance for underwater works and its dimensions are 0.75m*0.5m*0.5m. It has 4 thrusters of 450 watts for longitudinal/lateral/vertical propulsion and is equipped with a pressure sensor for measuring water depth and a magnetic compass for measuring heading angle. The navigation of the vehicle is controlled by an on-board Pentium III-class computer, which runs with the help of the Windows XP operating system. These give us an appropriate environment for developing various algorithms needed for developing and advancing Hovering AUV.

  • In trajectory-based navigation systems, a huge amount of trajectory data is needed for efficient route explorations. However, it would be very hard to collect trajectories from all the possible start and destination combinations. To provide a practical solution to this problem, we suggest a method combining collected GPS trajectories data into additional generated trajectories with new start and destination combinations without road information. We present a trajectory combination algorithm and its implementation with Scala programming language on Spark platform for big data processing. The experimental results proved that the proposed method can effectively populate the collected trajectories into valid trajectory paths more than three hundred times.

  • Tangible user interfaces have attracted strong attention in the HCI(Human and Computer Interface) community for their ability to take advantage of skills humans develop in the real world. We are developing "tangible media aided design system" which employs physical objects i.e., brick as interfacing media for 3D graphic modeling. This system is targeting for persons who are afraid of experiencing 3D graphic modeling and virtual space, or have a sense of reluctance in approaching to them. Our approach suggests the easiest way for people to experience computer system and virtual space carefree while developing and improving their space sense. This work is one of initial explorations of media aided design system using tangible user interfaces.
