  • Tuned mass dampers (TMD) are devices employed in vibration control since the beginning of the twentieth century. However, their implementation for controlling the seismic response in civil structures is more recent. While the efficiency of TMD on structures under far-field earthquakes has been demonstrated, the convenience of its employment against near-fault earthquakes is still under discussion. In this context, the study of this type of device is raised, not as an alternative to the seismic isolation, which is clearly a better choice for new buildings, but rather as an improvement in the structural safety of existing buildings. Seismic records with an impulsive character have been registered in the vicinity of faults that cause seismic events. In this paper, the ability of TMD to control the response of structures that experience inelastic deformations and eventually reach collapse subject to the action of such earthquakes is studied. The results of a series of nonlinear dynamic analyses are presented. These analyses are performed on a numerical model of a structure under the action of near-fault earthquakes. The structure analyzed in this study is a steel frame which behaves as a single degree of freedom (SDOF) system. TMD with different mass values are added on the numerical model of the structure, and the TMD performance is evaluated by comparing the response of the structure with and without the control device.

  • T. Nakai, who wrote Flora of Koreana vol. II in 1911, cited V. L. Komarov's collections and listed more than 120 specimens with ca. 65 localities. All collection sites cited were described in the Romanized characters based on the Russian pronunciation. Therefore, it is very difficult to pinpoint those sites using the current or old version of Korean map. From this study, many names were reviewed based on other studies (both the Russian version and the Japanese translated version) and records (e.g. specimen label) and presented based on the current provinces with local names, the Chinese character, the GPS data and the first page of citation.

  • Being a medium to help understand the status of the whole body including the Five Vital Organs and the Six Viscera such as the heart, the mac is considered to represent the elasticity of the blood vessel and the condition of the bloodstream in the Oriental medicine. A doctor makes a subjective judgment on a patient's conditions based on the information derived from the diagnosis and the medical examination of the mac wave. Thus he or she needs objective records and make a decision based on them in order to prevent misdiagnosis. This paper set out to suggest the ways to detect the particular parameters of the mac wave with the methods to visualize the mac wave interpretation to detect basic documents(causes) of health status judgment in three-dimension and with the simulation.

  • According to the original texts in "Hwangjenaegyeong(黃帝內經)", it's considered that the Chinese character Tong(洞) in the word of Tongseol(洞泄) should be understood as fast[疾] or rapid[速],and the main symptom of Tongseol should be diarrhea of indigested food soon after a meal. Through comparing Tongseol with Dongpung(迵風) in Historical Records, we can draw the conclusions as following. Firstly, the ancient physicians attached great importance to the role of wind in the pathogenesis of diarrhea. Secondly, perhaps the ancient physicians had these ideas of "wind is rapid" and "strong wind can bring shaken" as well as "wind is related to the liver closely" already in the early Western Han Dynasty. Thirdly, the rich materials about the relationship between wind and diarrhea in "Hwangjenaegyeong(黃帝內經)" should be considered as the successor to the excellent thinking of their predecessors.

  • This study is on Yun Seon Do's site located at Bogildo, Wando-gun, Jeonnam, compares the relics found through excavation to literature records and examines the character of relics and architectural features of the site. The results of this study are summarized as follows. First, bridge and pond including Goksudang and Seojae mentioned in related literatures were found around Goksudang. In the spatial composition, the area was divided into three using the stream from the valley and pond including buildings was built at each area. Each area was connected through Honggyo, Yueuigyo, and Ilsamgyo bridges and intentionally lengthened movement was considered as the space production technique to see the valley, and upper and lower pond. Second, 11 building relics, pond and fence were confirmed around Nakseojae. The transformative process of these relics could be divided into three periods. The 1st of these period was when Yun Seon Do lived there and Mumindang, pond and waterway were arranged as straight axis. Third, Dongcheonseoksil consisted of building relics (1) for preparing for and drinking tea and pavilion (building relics(2)) and pond, and these were static with nature and used as contemplative space for viewing.

  • This study was designed to establish Korean food culture by analyzing 17 sets of Jinyounuigue, Jinchanuigue, and Jinjarkuigue which were the records of royal party procedures in Yi dynasty, Analysis was made on royal parties in terms of table setting, kinds of dishes served, composition of foods, frequency of the food materials used, and food items changed over the period from 1719 to 1902, the latter half period of Yi dynasty. Foods used in those parties were classified into seven groups in this study; rice and noodoes, side dishes, Docks, desserts, fruits and nuts, beverages, and sauces. There were about 10 kinds of steamed rice and noodles including Mandoo and Byungtang, 140 different kinds of side dishes, 53 kinds of Kocks, 142 kinds of various desserts, especially Dasik and Korean cookies, 38 kinds of fruits and nuts, 10 kinds of beverages including Hwachae and Sujeongkwa, and 10 kinds of sauces such as soy sauce, mustard, honey, and etc. There was no tendency in omission or addition of food materials, but the number and heights of dishes were designated by the scale or character of the party. There were unique measuring units that were quite different from metric system. More than 30 different units were appeared in the differences. Most of them were used for typical items such as Sari for noodles only. However some were quite general and used until now. Mal and Dye were the units for volume, Kwan and Kuen for weight, and Chock and Chon for length.

  • The analysis of characteristics of water use evaluation and nighttime domestic flow evaluation was performed by using result from flow monitoring and surveying water supply records and nighttime domestic flow for a year. The analysis of correlations showed that, for both sites, the infiltration ratio and wastewater flow have shown a good relationship with high correlation factor and that the calculation of wastewater flow was highly affected by monthly rainfall depth as well as number of rain days. From this result, it was concluded that the measurement of infiltration should be performed when the rainfall does not significantly affect the sewer flow. Also, it is notable that each value of calculated using method for infiltration evaluation are not comparable to each other, but independent methods. In selecting of evaluation method for infiltration, therefore, a great emphasis should be imposed to the character of area and the seasonal factor in order to select optimal one. It is desirable way for evaluating infiltration and reduction ratio using result from an optimal method.

  • Extended path expressions are used to denote multiple paths concisely by using '$\ast$' character. They are convenient for expressing OQL queries to retrieve XML data stored in OODBs. In this paper, we propose a multi-path index scheme as a new index scheme to efficiently process queries with extended path expressions. Our proposed index scheme allocates a unique path identifier for every possible single path in an extended path expression and provides functionalities of both a single path indexing and multiple path indexing through the composition of index key and path identifier while using only a index structure. The proposed index scheme provides better performance than single-path index schemes, and is practical since it can be implemented by little modification of leaf records of a B+-tree index.

  • Candoninae is the most diverse group of freshwater ostracods with over 300 living species described from all around the world. However, only 11 species have been reported from South Korea. Considering abundant freshwater ecosystems here this number is very low. It is no wonder that newly collected samples of freshwater meiofauna often contain Candoninae ostracods which are new records for South Korea, or new taxa. Earicandona mounchyon gen. nov. sp. nov. and Typhlocypris (Pseudocandona) pratensis (Hartwig, 1901) were collected from two open freshwater bodies in Gangwon-do, and Gyeongsangbuk-do in South Korea. The new genus is most closely related to the breuili-group of Fabaeformiscandona Krstic, 1972. The most important apomorphic character of the new genus is a hemipenis with a poorly sclerified lobe "g", and prehensile palps with more rounded dorsal margins. Beside the new species, Earicandona contains only E. okuboi (Smith & Janz, 2008) comb. nov. from Lake Biwa. This species was originally described in Fabaeformiscandona, fabaeformis-group. They differ mostly in the morphology of the shell, but also some details of soft body, including the more pronounced genital process in the Korean species. Typhlocypris pratensis was so far known from Europe and this finding significantly broadens its area of distribution. Both Typhlocypris and Earicandona belong to the tribe Candonini and the key to the genera of this tribe is also presented here.

  • With the development of media and computer, Motion Capture system, recently used in the entertainment and computer graphics, is emerging as a new recording method. Motion Capture is a system that records time-varying position of sensors which are attached to a objects and translates it to 3-D coordinate on computer. The motion of object displays the time-varying positions of each sensors that are graphed, or the line connected man-shaped model's movements on the computer monitor. And by adding computer graphic character to it, the various angled images, which are difficult to be perceived on the stage, can be easily recorded. Recently in Japan, Motion Capture system is being actively studied in order to use it in recording and preserving the intangible cultural assets of dance and art. Especially, Warabiza in Tazawako art village at Akita plays the leading role in this area through the project to symbolize and establish the archive of cultural dance, further, Ritsumeikan Univ. is develops the system for coupling the motion capture system to Labanotation. This article introduces the motion capture and it's related studies in Japan, which are being actively studied as a new recording method of intangible cultural assets.
