This paper proposes a user interface, on see-through system environment which shows the images via two different cameras, that also ordinary user can control the computer systems or other various processes easily. For that, we include an AR technology to synthesize the virtual button to the image which is captured by the camera real-time. And we were looking for the hand position in the image to judge whether the figure selects the button. And the result of judgment visualizes through changing of the button color. The user can easily interact with the system by selecting the virtual button in the screen with watching the screen and moving her fingers at the air.

This study was carried out to evaluate the Life Cycle Cost(LCC) of three types of RTPV(Building Integrated Photovoltaic) systems-Glass plus Granite. Crystalline BIPV and See through Amorphous BIPV-which were vertically installed to generate the same power output(76 kW level). Initial investment costs. cost. savings and maintenance costs had been predicted during the period of analysing the LCC of three types of BIPV(Building Integrated Photovoltaic) systems installed for the purpose of evaluating the LCC. In case of cost savings, it had been analyzed by measuring the amount of electric power generated, reduction in lighting load and heat & cooling loads through simulation. From this analysis, it was predicted that the See-through amorphous BIPV offering cost saving advantages demonstrated the economical efficiency similar to the Class plus Granite when it is backed by more than 20 years of durability.

In the field of augmented reality technologies, commercial optical see-through-type wearable displays have difficulty providing immersive visual experiences, because users perceive different depths between virtual views on display surfaces and see-through views to the real world. Many cases of augmented reality applications have adopted eyeglasses-type displays (EGDs) for visualizing simple 2D information, or video see-through-type displays for minimizing virtual- and real-scene mismatch errors. In this paper, we introduce an innovative optical see-through-type wearable display hardware, called an EGD. In contrast to common head-mounted displays, which are intended for a wide field of view, our EGD provides more comfortable visual feedback at close range. Users of an EGD device can accurately manipulate close-range virtual objects and expand their view to distant real environments. To verify the feasibility of the EGD technology, subject-based experiments and analysis are performed. The analysis results and EGD-related application examples show that EGD is useful for visually expanding immersive 3D augmented environments consisting of multiple displays.

In order to effectively prevent and respond to disasters, several techniques have been developed in which the pilot wearing a see-through Head Mounted Display (HMD) performs disaster-related rescue activities using images transmitted from an Unmanned Aerial Vehicle (UAV). However, these techniques have limitations in quickly determining and executing tasks appropriate to the on-site situation because the pilot cannot recognize the entire field in an integrated manner. In order to overcome these problems, we propose an AR based-interface technique that allows the rescuer wearing a see-through HMD to operate a UAV efficiently. Simulation results show that the proposed interface technique allows the rescuer wearing a see-through HMD to control the gimbal and flight of the UAV at a high speed based on finger gestures in a visibility situation.

Objectives : The purpose of this paper is to study the form, contents and special features found in Qianhuang's life, books, his relationship with his disciples and Shanghansuyuanji's edition and its pass-ons. Methods : The best version among Shanghansuyuanji's copies was selected. Based on this, Qianhuang's life, books and his relationship with his disciples were studied, and Shanghansuyuanji's edition and its pass-ons, form and contents were analyzed. Results & Conclusions: Through study, first I see that Qianhuang was born in the early period of Qing Dynasty and died after the publication of Shanghansuyuanji, Suwen's annotation book probably had not been published yet, his mentor were Fangyouzhi and Yujiayan. Second, I see that he organized Shanghanlun sentences from his own perspective of cause of a disease and cure method. Third, I see that he viewed the diseases of six meridians with the perspective of yinyang and explained the concept of three yins and three yangs in relation to yinyang's ups and downs, and his Yuggyeongjasu theory made possible various interpretations of disease mechanism. Fourth, I see that he held critical views towards the Shanghanlun sentences through the Error Discrimination. Fifth, I see that he viewed disease mechaniam in interdependent relationships or from the point of view of the School of Warming and Tonifying through the Meaning of Herbal Formula. Sixth, I see that he sometimes quoted Neijing in proper ways that fit the disease mechanism in Shanghanlun. On the other hand, he quoted Neijing solely for the reason that identical words are used, but some of these were not proper. Additionally, he criticized the aforementioned annotators for improper quoting Neijing. Consequentially, for reasons mentioned above Qianhuang's Shanghansuyuanji has great importance as a Shanghanlun annotation book.

Labyrinth seals are commonly used in various kinds of turbomachinery to reduce leakage flow. In the present 3D CFD analysis of see-through-type labyrinth air seal, the methodology of determining leakage and rotordynamic coefficients is suggested with the relative coordinate system for steady-state simulation. The leakage flow and rotordynamic forces predicted by using different solvers and turbulent models of FLUENT are compared with the results of the existing bulk-flow analysis code LABYSEAL.FOR and experiment. The present CFD result of direct stiffness(K) shows only improvement in prediction. The results of leakage and rotordynamic coefficients as well as computing time are sensitive against the used solver and turbulent model.

This study is on the sewing construction of the 17th century clothing through the Excavated Costumes in O-chang, ChungBuk in 1998. The followings are the results of this study. There are various sewing constructions in this excavates costume : a running stitch.a back stitch.a half back stitch.a french seam.a gobsol(korean traditional seam sewing). We can see that the sewing construction of the 17th century-clothing depends on construction styles : one layer, two layers, clothing padded with cotton(include quilt). We can see that sewing construction in the one taler clothing consisted of a running stitch, a french seam, a gobsol seam. In the two layer clothing the construction included a running stitch and half back stitch. a running switch and a decorated top stitch(3stitch) were used in the clothing padded with cotton. We can see that the sewing construction enhanced the function of keeping the shape of clothing and the raw edges. We can see that the shape of clothing is important in presentation of aesthetic of the clothing. Such a kind of sewing construction lasted from the early Chosen Dynasty through the 17th century.

This study investigated the luxury supply chain management called 'See now, Buy now'. This has been a new way of controlling the supply and demand for luxury brands in the fashion industry since 2016. In this study, we explored the backgrounds and impacts of 'See now, Buy now' in the digital era. 'See now, Buy now' was launched by the fashion brand, Burberry in February 2016. It was the first luxury brand to showcase its entire collection using 'See now, Buy now' among the brands which showcase in Paris, Milan, New York, and London fashion weeks. That has not only caused many controversies in the fashion world but also generated followers. In this study, we analyzed 'See now, Buy now' in three aspects, economics, efficiency, and management strategy, and this was done through a literature survey on articles pertaining to 'See now, Buy now' and empirical surveys on Burberry's collections. Based on 'See now, Buy now', Burberry tried a new process of supply and sale. In the era of SNS, the spread of information is getting faster. The speed of SNS and changes in the fashion market combining IT and mobile technology are major changes faced by the fashion industry. 'See now, Buy now', a model of the new supply and demand in luxury fashion brands, should be noted as a new directional aspect for the future of the fashion industry. Since it was a relatively recent trend that started from the September show of Burberry in 2016, there was still a lack of academic discussion or prior research on this phenomenon. Therefore this study aimed to predict future directions by recognizing the importance of 'See now, Buy now' in the fashion industry. Also, based on this research, the significance of this study was to present a management strategy that applies 'See now, Buy now' to the future of the fashion industry in the digital era.
