Tree-ring chronologies can be used to date historical buildings by matching them with the chronologies of living trees or previously dated samples. Tree-ring dating gives a calendar year to each tree ring and produces the felling dates of logs or woods which had been used for buildings. In Korea, several chronologies of Japanese red pine(Pinus densiflora Sieb. et Zucc., 'sonamu' in Korean), a major species for the wooden building materials, have been developed and used for dating historical buildings. In this study, Tongmyungjeon Hall of Changkyung Palace in Seoul was dated by tree rings. The present Tongmyungjeon Hall was known to be reconstructed in A.D. 1834 after burned-out in A.D. 1790. We sampled total of 122 wood samples which were replaced during the repair process in 2002-2003. Felling dates of the samples were determined by the dendrochronological crossdating method. Crossdating method employs graphic comparison of the master patterns (ring-width chronologies of known dates) with those of the sample chronologies of unknown dates. Tree-ring dates confirmed that the reconstruction of 1834 utilized second-handed timbers as well as fresh-cut ones. The felling dates of wooden floor frames were mostly A.D. 1913, indicating the 'Ondol' floors were changed to the wooden floors around 1914 when the Japanese rulers brutally destroyed the royal Korean Palaces and transformed palace buildings to their offices or exhibition halls after occupying Korea in 1910. This study proved that tree-ring dating was a useful and accurate method to identify the critical dates for the history of Korean traditional buildings.

Chinyoung(親迎) is one of the detailed procedures of a wedding ceremony, of which the bridegroom visits the bride's home to receive and bring her to his home. And, Procession Illustration (班次圖) is a type of drawing that shows how people of various social classes are arranged in their predetermined positions in a royal ceremony. Thus, 'Chinyoung Procession Illustration(親迎班次圖)' refers to the drawing of the march in the course of Joseon's royal wedding ceremony, in which the bridegroom receives and brings the bride to his home. This paper aims to reconstruct the Chinyoung Procession Illustration for a princess as an image, which has never been done. There are no drawings or pictures of the princesses' Chinyoung Procession, but only written records. Thus, we completed the Procession Illustration by dressing the participants in accordance with their social classes and arranging them in the march. The arrangements were based on historical records of social classes, positions, number, and costumes. As for the princesses' weddings in the late Joseon period, a total of 18 wedding records remain. We selected Princess Bok-On's (福溫公主: 1818~1832) wedding as the subject of reconstruction as it had the greatest number of participants. In addition, due to the great number of participants, this study limits its focus to the female participants, with the male participants to be examined in future research. The result confirmed that the number of participants in Princess Bok-On's Chinyoung Procession was 184, including the bride and bridegroom, and the number of female participants was 26 in total, including the princess and women placed around her. The women participants wore Rip(笠), Neoul(羅兀), Jeonmo(氈帽), Garima(加里磨), Noeui(露衣), Hwaleui(豁衣), Dangeui(唐衣), Jeogori(赤古里), Chima(赤亇), Malgun(袜裙), Daedae(大帶), Onhye(溫鞋), Dokhye(禿鞋).

" Analyzing on an object in the sphere of domestic law with the method of international law" has been already on the horizon in international law. For the lawyers of international law and space law, it is quite natural that they utilize the method of international law, whatever objects they may choice. The reason is that the characteristic of international law do not depend upon object in itself, but depend upon method in itself. The object of this paper is the idea of Peaceful Use(IPU or PU) in Japanese Space Policy. The method to be applied to this analysis is the international law's interpretation theory on legal principles, i.e., the method of international law. One of the aims of this paper is to explain critically the need of review on IPU in Japanese Space Policy; in particular with respect to the positive reconstruction of IPU through historical analyzing on the transfiguration and the mere shell of the Post-War Japanese Pacifism(PJP) as the starting point of IPU The historical process of the transfiguration and the mere shell is as followed .i.e.," from the ultranationalism in the pre-war Japan to PJP in the post-war Japan, from PJP to IPU, and from IPU to IPU's regression. In particular with respect to the interpretation theory, the meaning of the teleological, aims and objects school's approach on the interpretation of legal principles(P) has been emphasized. The reason is that the promising development of IPU will be realized by cooperating with the interpretation theory on P in international law. At the end of the beginning, I'd like to quote K. Marx's thesis in order to make the positions and missions the lawyers of international law and space clear. It is as follows, i.e.," THE PHILOSOPHERS HAVE ONLY INTERPRETED THE WORLD IN VARIOUS WAYS - THE POINT, HOWEVER IS TO CHANGE IT.

Objective: Postoperative dynamic cryo-compression (DC) therapy has been proposed as a method of reducing pain and the inflammatory response in the early postoperative period after orthopedic joint reconstruction surgery. Our aim was to analyze the analgesic efficacy of DC therapy after adult lumbar spinal surgery. Methods: DC was applied for 30 minutes every 6 hours after surgery. Pain was measured by a visual analogue scale (VAS) in the preoperative period, immediately after surgery, and every 6 hours postoperatively for the first 72 hours of the hospital stay. Patients' pain medication requirements were monitored using the patient-controlled analgesia system and patient charts. Twenty patients who received DC therapy were compared to 20 historical controls who were matched for demographic and surgical variables. Results: In the postanesthesia care unit, the mean VAS back pain score was $5.87{\pm}0.9$ in the DC group and $6.95{\pm}1.0$ (p=0.001) in the control group. The corresponding mean VAS scores for the DC vs. control groups were $3.8{\pm}1.1$ vs. $5.4{\pm}0.7$ (p < 0.001) at 6 hours postoperatively, and $2.7{\pm}0.7$ vs. $6.25{\pm}0.9$ (p<0.001) at discharge, respectively. The cumulative mean analgesic consumption of paracetamol, tenoxicam, and tramadol in the DC group vs. control group was $3,733.3{\pm}562.7mg$ vs. $4,633.3{\pm}693.5mg$ (p<0.005), $53.3{\pm}19.5mg$ vs. $85.3{\pm}33.4mg$ (p<0.005), and $63.3{\pm}83.4mg$ vs. $393.3{\pm}79.9mg$ (p<0.0001), respectively. Conclusion: The results of this study demonstrated a positive association between the use of DC therapy and accelerated improvement in patients during early rehabilitation after adult spine surgery compared to patients who were treated with painkillers only.

To discuss whether we have credible estimations about historical surface temperature evolution since industrial revolution or not, present study investigates consistencies and differences of averaged surface air temperature since 1900 between the multiple data sources: Hadley Center Climate Research Unit (HadCRU4) surface air temperature data, ECMWF 20 Century Reanalysis data (ERA20CR), and NCEP 20 Century Reanalysis data (NCEP20CR). Averaged surface temperatures are obtained for the global, polar (90S~60S, 60N~0N), midlatitude (60S~30S, 30N~60N), tropical (30S~30N) region, separately. From the analysis, we show that: 1) spatio-temporal inhomogenity and scarcity of HadCRU4 data are not major obstacles in the reliable estimation of global surface air temperature. 2) Globally averaged temperature variability is largely contributed by those of tropical and midlatitude, which occupy more than 70% of earth surface in area. 3) Both data show consistent temperature variability in tropical region. 4) ERA20CR does not capture warm period over Arctic region in early 1900s, which is obvious feature in HadCRU4 data. Discrepancies among datasets suggest that high-level caution is needed especially in the interpretation of large Arctic warming in the early 1900s, which is often regarded as a natural variability in the Arctic region.

The current cultural assets are being restored depending on the opinions of experts (craftsmen). We intend to introduce digitalized artificial intelligence techniques, excluding the personal opinions of experts on reconstruction of such cultural properties. The first step toward restoring digitized cultural properties is separation. The restoration of cultural properties should be reorganized based on recorded documents, period historical backgrounds and regional characteristics. The cultural properties in the form of photographs or images should be collected by separating the background. In addition, when restoring cultural properties most of them depend a lot on the tendency of the restoring person workers. As a result, it often occurs when there is a problem in the accuracy and reliability of restoration of cultural properties. In this study, we propose a search method for learning stored digital cultural assets using AI technology. Pagoda was selected for restoration of Cultural Properties. Pagoda data collection was collected through the Internet and various historical records. The pagoda data was classified by period and region, and grouped into similar buildings. The collected data was learned by applying the well-known CNN algorithm for artificial intelligence learning. The pagoda search used Yolo Marker to mark the tower shape. The tower was used a total of about 100-10,000 pagoda data. In conclusion, it was confirmed that the probability of searching for a tower differs according to the number of pagoda pictures and the number of learning iterations. Finally, it was confirmed that the number of 500 towers and the epochs in training of 8000 times were good. If the test result exceeds 8,000 times, it becomes overfitting. All so, I found a phenomenon that the recognition rate drops when the enemy repeatedly learns more than 8,000 times. As a result of this study, it is believed that it will be helpful in data gathering to increase the accuracy of tower restoration.

Currently, most of content restoration using artificial intelligence learning is 2D learning. However, 3D form of artificial intelligence learning is in an incomplete state due to the disadvantage of requiring a lot of computation and learning speed from the existing 2 axes (X, Y) to 3 axes (X, Y, Z). The purpose of this paper is to secure a data-set for artificial intelligence learning by analyzing and 3D modeling the stone pagodas of ourinari by era based on the two-dimensional information (image) of cultural assets. In addition, we analyzed the differences and characteristics of towers in each era in Korea, and proposed a feature modeling method suitable for artificial intelligence learning. Restoration of cultural properties relies on a variety of materials, expert techniques and historical archives. By recording and managing the information necessary for the restoration of cultural properties through this study, it is expected that it will be used as an important documentary heritage for restoring and maintaining Korean traditional pagodas in the future.

This study focuses on the genealogical analysis of the urban public spaces by the local history of Seoul which is significantly different from western cities. The analysis targets the discourse of the urban street which defines urban space-structure among the urban public spaces. Based on the analysis, we define the progress levels of urban public design policy in Seoul. Firstly, in 1960's and 1970's, 'urban reconstruction' was intensively carried out for the country modernization, and 'vehicle preferred street expansion' resulted in damages to historical inheritance, in-humanized street, and cultural uniformity. 1980's and 1990's would be defined as 'politic acceptance of plural values to the urban street.' There were the Olympic Games held in Seoul in 1988, which were the celebrations of the 600th capital establishment and the autonomous local government system. In the meanwhile, diverse values on the urban street were discussed in terms of globalization. There also were the self-reflection for the urban skyscrapers and high-population rate, the cultural uniformity of urban street, and the commercialization in downtown with urban reconstruction plans. Then, the sense of landscape and amenity was focused. Various urban projects and regulations were held according to the changes of value recognition. 2000's can be defined as 'introduction to the organic integration and the urban public design governance.' In the 21st century, types of recognition have changed significantly, which include publicness, humanism, sustainability, symbolism, artistry, placeness, and communication. They cause the establishment of ordinances and the installation of integrated organization via urban design administration. The legislation has been revised in order to support the various methods for the maintenance and operation of urban landscape in terms of local characteristics. New regulations were established for residents to participate in the processes of the urban planning with street design policy.

The Nam-Hae Sin-sa, the South Sea shrine in Yeong-Am, Korea was a national institution for public peace and bliss, was excavated in 2000, and the shrine and the 3-way-gate were reconstructed in 2001. Hae Sin-sa, the Sea shrine is a place for religious service separated into the Nam-Hae Sin-sa, the Dong-Hae Myo, and the Seo-Hae Dan. The Dong-Hae Myo was reconstructed, but restored shrine and 3-way-gate of the Nam-Hae Sin-sa is not perfect in comparison with excavation plan in 2000, therefore new reconstruction was researched through the related literature, the analysis of historical maps and excavation results, the interview with the concerned people and the case study. This research defines the analysis of the Plan of the Nam-Hae Sin-sa Reconstruction as follows. 1. The Nam-Hae Sin-sa was the institution for religious service operated by national direct management, represents the shrine for public peace and bliss on the Mountain, the Sea, and the River. Especially the Nam-Hae Sin-sa had an important position on the pivot of international trade with China and Japan, and had a role of main shrine with another one in the Mt. Ji-ri San. 2. The name of the Sea shrine was called as Nam-Hae Sin-sa(the South Sea shrine), Dong-Hae Myo(the East Sea shrine), Seo-Hae Dan(the West Sea shrine). But the name of the South Sea shrine had changed in the early period of Chosun as Nam-Hae Sin-sa to the later Chosun as Nam-Hae Dang through the research of related literature and historical map. Such as the Seo-Hae Dan, it was constructed for the Dan, the flat raised-floor without buildings, and changed to the type of Sa-Dang with addition of buildings. 3. The historical map of Hae Sin-sa informs the types of the roof, the Mat-bae roof was used in the Dong-Hae Myo, but the Pal-jak roof was showed in the Seo-Hae Dan and the Nam-Hae Sin-sa. 4. According to the analysis of Yong-Ch'uck the unit length, Nam-Hae Sin-sa was reconstructed in the period of Koryo on large scale, but it was restored in the Chosun on middle scale. And the Unit of Yong Ch'uck was changed into Yeong-jo Ch'uck in the period of Chosun. 5. As the results, The Plan of the Nam-Hae Sin-sa Reconstruction designed the new shrine into the 3 Kan front and the 2 Kan side with 3:2 scale. An-ch'o-gong with Yong-du and Yong Mi the ornaments represents head and tail of dragon, the Un-gong and the ornament of Pa-ryun-dae-gong in the building, and the Ch'ung-ryang of the Yong-du show the image of the institution for religious service for the god of the sea who look like dragon. The inner gate building and the main entrance were designed as same plan and scale as Hyang-gyo, the Korean Traditional School and Shrine of Confucianism, on the basis of results of excavation. Raise the 3-tall gate of the main entrance with harmony of the scale and the shape, because the side of gate building has the Mat-bae roof. 6. This research shows that Plan of the Nam-Hae Sin-sa Reconstruction is composed into shrine space and reservation space from the main entrance to inner gate and shrine like Jung-ak Dan in the Mt. Gye-ryong San, and it also informs the well in the west side of Sin-sa is an important factor of the plan of shrine architecture.
