박재우,신실,손숙자 대한피부과학회 1981 大韓皮膚科學會誌 Vol.19 No.6

The CRST syndrome, first reported by Winterbauer, represents a benign variant of scleroderma and consists of calcinosis(C), Raynauds phenomenon(R), sclerodactyly(S) and telangiectasia(T). The authors report a case of CRST syndrome confirmed by both clinical and histopathological findings. A 62-year-old female developed subcutaneous nodules on both elbow and knee joints, Raynauds phenomenon, sclerodactyly with acrosclerosis and scleroderrnatous changes on both hands and forearms and telangiectasia on the face, neck, and hands of 15 years duration, but she had no difficulty in swallowing. The authors treated a case of CRST syndrome with weekly intra-arterial administration of reserpine and were impressed not only by the marked loosening of the skin but also by the striking effect on the Raynauds phenornena; the latter disappeared within a few weeks of treatment.

It was understood that the peace during the war between Goryeo and Mongolia was promoted by civil ministers. So It wasn't interested in the role of the military subjects. However, in the second half of the Goryeo and Mongolian wars, both civil ministers and military subjects participated in the promotion of the peace. Therefore, it is necessary to have a balanced understanding of the promotion of peace. The military subjects engaged in diplomatic activities promoting peace with civil ministers. The diplomatic ambassadors of civil ministers and military subjects served to stop the Mongol invasion, withdraw the Mongolian army, and end the war. Jaechus led discussion of the peace. The civil ministers and military subjects of the 3-4 ranks did not differ from those of the Jaechus. The Jaechus of civil ministers and military subjects were discussed at the policy meeting for the promotion of peace and the end of the war. Jaechus, who promoted peace, agreed to peace without distinction between civil ministers and military subjects, and were active in promoting peace. Jaechus had many family members and party members of the Choi's regime, and they led the peace discussion. It was because they were supported by the Choi's regime and had greater influence in the bureaucratic society than other bureaucrats. There were reasons for promoting the peace together with civil ministers and military subjects. Mongolia's offensive threatened the national destiny, the political and military centripetal power of the Choi's regime weakened, the bond of the family and the party weakened, and the even if the Choi's regime collapsed, it was able to maintain the position of the ruling class. The promotion of peace in the second half of the war between Goryeo and Mongolia must be seen as pursued by civil ministers and military subjects.

The military generals who seized power as well as control over the government with armed forces did not abandon the civil system of administration entirely, and instead decided to use it to their favor in order to wield more power. This kind of trend was reinforced during the Choi regime. Choi Chung-heon gained control of the government, and was appointed to many illustrious posts, including the prime minister seats, heads of the Ibu and Byeongbu offices, head of the monitors office and also that of the supreme commander. Choi Ih and Choi Hang also walked the same path, while Choi Eui was assassinated before he was able to secure such posts. Leaders of the Choi house intended to exclude the Ibu and Byeongbu offices from the governmental appointment process, and wanted to monopolize the authority to select and appoint governmental officials. They used another location other than the palace for the process, such as private civilian residences or the Jeongbang hall. It should be noted that all the appointments authorized them were not illegally processed ones based upon unjustified and unwarranted use of authority. At the time the people behind such processes, the Choi house leaders, were already assigned to the head posts of Ibu and Byeongbu, and were legally authorized to intervene in the appointment processes. The appointment orders were issued from private places, but they were issued by entities who were entitled to do so. The process too was not to select private servants for the Choi house, so it was recognized and acknowledged as official functions of the government. The Choi regime leaders who had stronger power than the king, used their own authority and power as heads of the Ibu and Byeongbu offices. This shows us that even during the military regime period, Goryeo’s administrative system was still functioning. The Choi regime did not abandon it or replace it with yet other ruling system, but wielded its power by seizing control of the administrative system itself. The installation of the Jeongbang(政房) office was also intended to do just that, monopolizing the official appointment process in order to get control over the entire administrative system.

Recently, as the importance of eco-friendly energy has increased hydrogen gas is in the spotlight as future energy. Due to its special properties, hydrogen gas is more difficult to detect requiring more precise sensing technology. The primary objective of this study is to design a concept of an underground hydrogen pipeline monitoring system. For this, the following research works are conducted sequentially; 1)selection of core technology for conceptual design, 2)state-of-the-art review, 3)design of a concept of the system. As a result, DAS(Distributed Acoustic Sensing), and DTS(Distributed Temperature Sensing) are selected as each core technology. Furthermore, a conceptual design of an underground hydrogen pipeline monitoring system is deducted. It is expected that the impact on the eco-friendly energy industry will be enormous due to the increasing interest in using hydrogen energy.

Recently, research and development to revitalize smart construction are being actively carried out. Accordingly, 3D mapping technology that digitizes construction site is drawing attention. To create a 3D digital map for construction site a point cloud generation method based on LiDAR(Light detection and ranging) using MMS(Mobile mapping system) is mainly used. The purpose of this study is to analyze the accuracy of MMS LiDAR-based point cloud data. As a result, accuracy of MMS point cloud data was analyzed as dx = 0.048m, dy = 0.018m, dz = 0.045m on average. In future studies, accuracy comparison of point cloud data produced via UAV(Unmanned aerial vegicle) photogrammetry and MMS LiDAR should be studied.

This paper presents the results from a hydrodynamic model study to predict the impacts of coastal reclamation in Pusan harbor system using RMA2 which is a tidal flow model of the US Army Corps of Engineers' TABS-2 system. A finite element mesh was constructed and refined to cover the complicated geometry of Pusan harbor system and the proposed reclamation area. The model was calibrated to tidal elevations and currents measured during spring fall syzygys. Under the three different tidal conditions including summer winter syzygys, spring fall quarters, and summer winter quarters, the model predictions were compared with the field measurements both in tidal elevation and current. In all cases, there were excellent agreements between the model predictions and the field measurements. The validated model was then used to predict the changes in tidal current and elevation that might occur due to the coastal reclamation. It was predicted that there would be no change in tidal elevation of this system after the reclamation. In tidal current, however, discernible changes were predicted near the proposed reclamation area both in magnitude and direction.

The perception of earthquake in Korea has changed due to the earthquake that occurred in Gyeongju and Pohang, and the earthquake has become an important factor in infrastructure management. Damage to infrastructures in the event of an earthquake is extensive. In particular, damage to infrastructures that perform public function used to spread to the whole area. From the point of view of earthquake disaster prevention, it is very important for the public to define what infrastructures are important management targets and to prepare a countermeasure. In this study, we propose a method to evaluate the importance of infrastructure to effectively manage infrastructures for earthquakes. For this purpose, important factors for the railway bridges, power generation and electric power facilities, and apartment complexes are suggested. AHP analysis is conducted to suggest priorities. In addition, the evaluation criteria for infrastructure importance are presented.

Researches utilizing the fourth industrial revolution technology are being conducted as a breakthrough for improving the earthworker productivity. In order to make the earthwork site smarter, it is necessary to digitize the construction site topography at first. For this purpose, photogrammetry using drones and LiDAR on MMS have been recently used. The purpose of this study is to analyze the accuracy of LiDAR by installation angles for verifying the application of MMS in the construction site. As a result of comparing the coordinates measured by the total station and the LiDAR, a small error of about 1-2 centimeters was shown. It is confirmed that MMS could be well applied to the earthwork site. In addition, there was no significant difference in the accuracy of the acquired coordinates according to the installation angle of the LiDAR, but the shape of the point clouds was different. The larger the installation angle, the better the shape of the site terrain is measured.
