The palace byeoljeon(別殿), the King's non-ceremonial space, were created as a space for the king to comfortably use and for the king to do what he wanted to do. The byeoljeon housed various types of spaces and were flexible in that they could be repurposed to meet the demands of the times. Nevertheless, their characteristic as palatial building created for the King's convenience has remained unchanged. In this study, we examine the process by which such royal spaces were created by focusing on the reconstruction of the Changdeokgung Huijeongdang during Japanese occupation period, with a view to continuity and the transformation process. The reconstruction of Huijeongdang at the time may be considered along internal and external characteristics. Internally, Huijeongdang connected the symbolism of the king's space as the palace byeoljeon. Externally, Huijeongdang is characterized by its mixture of traditional and western style, where western style structures were housed within traditional buildings. The plans for the block of Huijeongdang also included the coexistence of traditional building, western style building, and mixture of traditional and western style building. This reflects the characteristic continuity of the byeoljeon as well as the architectural techniques of the time, manifested together within a specific spatial block.

After the Korean war, two major attempts were made to reconstruct Gwanghwamun Gate as an important part of Korea's lost cultural heritage. In December 2006, the Korean government replaced the concrete gate with a wooden one, yet traces of the attempts made in the 1960s to transform Gwanghwamun Gate and the main road remain to this day. At the time, the Third Republic of Korea, sought to legitimize itself in the name of modernity, and went on to modernize the architecture and urban landscape of Seoul. The location and design selected for the rebuilt Gwanghwamun illustrated the symbolic relationship between historic heritage and urban development. The reconstruction of the gate began as part of the Third Republic's project to restore the Central Administration Building and culminated in the transformation of the main road in front of the gate. By reconstructing the traditional gate using concrete, the military government intended to convey the message that we could inherit our proud tradition using modern materials, and that we should actively adopt the new technologies of the modern era. This study begins with the premise that the Gwanghwamun reconstruction project of 1968 represents the application of new technological thinking to Korea's architectural style, and has two objectives. The first is to summarize the reconstruction process and method using the records and drawings from the 1968 project, which was then under the leadership of architect Kang Bong-jin. The second is to analyze the characteristics of the architectural style and structure of the reconstructed Gwanghwamun so as to reinterpret the relationship between Korean tradition and modern technology.

Purpose: Traditional radical surgery for vulvar cancer produces severe skin and soft tissue defects in the vulvar and vaginal area. Vulvoperineal V-Y advancement fasciocutaneous flaps have limitations in advancement and tension at the wound margin and vaginal orifice area, causing wound disruption or vaginal wall exposure. Therefore, we designed the "Butterfly flap" using a vulvoperineal V-Y advancement fasciocutaneous flap and an inguinal rotational skin flap for 3-dimensional reconstruction of vagina and vulvar area. Methods: A 27 year-old female was diagnosed with vulvar intraepithelial neoplasia. Radical vulvectomy and full-thickness-skin-graft was performed. We designed a vulvoperineal V-Y advancement fasciocutaneous flap as the greater wing and inguinal rotational skin as the lesser wing. After flap elevation, the inguinal flap was rotated $180^{\circ}$ to reconstruct the labia major and vaginal orifice. The perineum was reconstructed using V-Y advancement flaps. Results: The flap survived completely, without any complications. After 6 months, the patient was able to perform normal sexual activities and after 18 months, the patient was able to give birth to normal child by caesarean section. Conclusion: The traditional vulvoperineal V-Y advancement fasciocutaneous flap is thin, reliable, easily elevated and matches local skin quality. However, the vaginal wall becomes exposed due to limited advancement and tension of the flap. The "Butterfly flap" using a vulvoperineal V-Y advancement fasciocutaneous flap and an inguinal rotational skin flap is useful for the release of vaginal orifice contracture, reconstruction of the labia major, and 3-dimensional reconstruction of vagina and vulvar area.

With the development of computer-aided design/computer-aided manufacturing (CAD/CAM) technology, it has been possible to reconstruct the cranio-maxillofacial defect with more accurate preoperative planning, precise patient-specific implants (PSIs), and shorter operation times. The manufacturing processes include subtractive manufacturing and additive manufacturing and should be selected in consideration of the material type, available technology, post-processing, accuracy, lead time, properties, and surface quality. Materials such as titanium, polyethylene, polyetheretherketone (PEEK), hydroxyapatite (HA), poly-DL-lactic acid (PDLLA), polylactide-co-glycolide acid (PLGA), and calcium phosphate are used. Design methods for the reconstruction of cranio-maxillofacial defects include the use of a pre-operative model printed with pre-operative data, printing a cutting guide or template after virtual surgery, a model after virtual surgery printed with reconstructed data using a mirror image, and manufacturing PSIs by directly obtaining PSI data after reconstruction using a mirror image. By selecting the appropriate design method, manufacturing process, and implant material according to the case, it is possible to obtain a more accurate surgical procedure, reduced operation time, the prevention of various complications that can occur using the traditional method, and predictive results compared to the traditional method.

The accuracy and integrity of stress data acquired by bridge heath monitoring system is of significant importance for bridge safety assessment. However, the missing and abnormal data are inevitably existed in a realistic monitoring system. This paper presents a data reconstruction approach for bridge heath monitoring based on the wavelet multi-resolution analysis and support vector machine (SVM). The proposed method has been applied for data imputation based on the recorded data by the structural health monitoring (SHM) system instrumented on a prestressed concrete cable-stayed bridge. The effectiveness and accuracy of the proposed wavelet-based SVM prediction method is examined by comparing with the traditional autoregression moving average (ARMA) method and SVM prediction method without wavelet multi-resolution analysis in accordance with the prediction errors. The data reconstruction analysis based on 5-day and 1-day continuous stress history data with obvious preternatural signals is performed to examine the effect of sample size on the accuracy of data reconstruction. The results indicate that the proposed data reconstruction approach based on wavelet multi-resolution analysis and SVM is an effective tool for missing data imputation or preternatural signal replacement, which can serve as a solid foundation for the purpose of accurately evaluating the safety of bridge structures.

Purpose: The most accepted method for the reanimation of a paralyzed face is the two-stage method that combines cross-face nerve grafting with free-muscle transfer. Although the results of reconstruction with this method are satisfactory, there is an excessive delay between the stages, which prolongs the period of rehabilitation. In order to overcome this drawback, a one- stage, neurovascular free-flap reconstruction method using free neurovascular muscle flaps is introduced. Methods: From 1994 to 2004, 35 patients with longstanding facial palsy were treated. Fifteen patients underwent the single-stage reconstruction with the latissimus dorsi muscle, and 20 patients underwent the two-stage reconstruction method with the gracilis muscle. We compared the long-term results of the two methods of reconstruction. The mean follow-up period was 28.7 months for one-stage reconstruction, and 35.2 months for the two-stage, respectively. Results: In the patient group of the single stage reconstruction, both mouth corner excursion and animation grade were markedly improved at the final postoperative visit. Moreover, the first muscle contraction occurred earlier in this group, than in the two-stage reconstruction group. However, four patients in the single stage group never achieved a first muscle contraction or mouth corner excursion. Conclusion: Facial palsy is a very challenging condition for cosmetic surgeons to deal with. Traditional methods for treatment of chronic facial palsy use a two-stage muscle flap which is time-consuming and burdensome to patients, many of whom are averse to waiting 8 to 12 months to complete the two stages. The one-stage reconstruction method described herein uses a latissimus dorsi free-flap and has demonstrated consistent positive outcomes in clinical assessments.

In the early 20th century, Walter Benjamin analyzed the changes in the value of traditional art forms under the industrial era and the changes in the aesthetic attitude of the masses. A century later, in the contemporary multi-art world, the traditional medium of shelf painting is once again experiencing a similar situation as the last century. Emerging technology display modes such as digital virtual reality and digital immersive experience can achieve digital reproduction of paintings on shelves and reach a certain level of performance, which once again shocks the public's aesthetic perception. This paper attempts to illustrate the outstanding characteristics of the new art form after digital reconstruction by exploring the transformation and sublimation of digital technology to shelf painting. We predict that art research on future reality and augmented reality according to the artificial intelligence era will be conducted in depth in the future.

This study aims to find architectural characteristic of Nam-kwan-wang-myo as known as Nam-myo, Especially focusing on difference between before and after it's reconstruction in 1899. Nam-kwan-wang-myo is a shrine for Kwan-woo who was warlord in ancient china. Belief of Kwan-Woo was introduced to Korea in Japanese invasion of 1592 and the shrine was built in 1598. Belief of Kwan-Woo diffused for the late Joseon, during the reign of Gojong, many people have faith in Kwan-Woo including the king. There was four Kwan-wang-myo around the Hanyang at that time. In 1899 a fire of unknown cause broke out at Nam-kwan-wang-myo, so the main buildings burned down. The king instructed reconstruction of the shrine even though there was in financial difficulties, it had done in the midst of a national crisis. The buildings almost restored as before. The buildings in the shrine has strong characteristics of Chinese architecture because it made by people of the Ming dynasty. Two side-by-side roofs, accumulated brick exterior are important architectural feature, but also all the buildings in the mail hall area Surrounded by the closed-connected fence is hard to find examples in Korea traditional architecture. And Nam-kwan-wang-myo just had maintained architectural characteristics including layout of buildings, shape of the each building until it's reconstruction(1899).
