This study suggests a prediction model of ground motion spectral shape considering characteristics of earthquake records in Korea. Based on the Graizer and Kalkan's prediction procedure, a spectral shape model is defined as a continuous function of period in order to improve the complex problems of the conventional models. The approximate spectral shape function is then developed with parameters such as moment magnitude, fault distance, and average shear velocity of independent variables. This paper finally determines estimator coefficients of subfunctions which explain the corelation among the independent variables using the nonlinear optimization. As a result of generating the prediction model of ground motion spectral shape, the ground motion spectral shape well estimates the response spectrum of earthquake recordings in Korea.

This study was conducted to analyze the characteristics of records related to Korea shown in the cataloging records of major 10 Asia-Pacific university libraries. The results are as follows. To begin with, Korea-related records in most university libraries are very poor except for some libraries and are generally 2 times less than Japan related records. There are even 6 times less in 2 libraries. Second, most libraries organize records in MARC 21 format rather than UNIMARC, and apply subject headings of the national library, or go together with LCSH. Third, Korean materials usually write Korean in Roman characters, but 5 libraries are marked with the original Korean language and available Hangeul search. Forth, on investigation of the subject distribution in sub criteria of Korea-related records, subject related to 'history', 'economy', and 'politics' is largely shown in the highest rate. Fifth, Among the Korea-related subject heading, the terms such as 'Taekwondo', 'Kimchi', 'Dokdo', 'Donghae', 'Duman-gang', 'Baekdu-san' have different meanings in different libraries. However, these terms agree to LCSH in most libraries except for neighboring countries's libraries.

To determine the vertical dimension and centric relation during the construction of implant overdentures, the record base and wax rim may need to be adjusted. The conventional method has several drawbacks, as it requires repeated tightening and loosening of the impression coping. Here, we report a useful and novel method for interocclusal records using the healing abutments in implant overdentures. Our case demonstrates that this method is easier and simpler and prevents gingival collapse.

Objectives : Many curative methods are used utilized in order to rid human body of disease when people become sick. Traditional Korean medicine generally prescribe methods that involve acupunture, moxibustion, or herb formulae. However, different types of foods are sometimes used as well. While wondering the history and efficacy of Qi-elevation foods that were consumed by Koreans in the past, the author discovered that a record from the Joseon Dynasty, called The Daily Record of Royal Secretariat of Joseon Dynasty, henceforth the Records, contained information about different types of porridge. Hence, the author looked through the records of porridge as written in the historical material in an attempt to learn the examples and efficacy of medicine-porridge consumed in Joseon's royal palace. Methods : After searching for the keyword, 'porridge', in the Records as provided by the National Institute of Korean History, the author extracted the porridges recorded during the Yeongjo period that each has its own special name. Results : Different types of porridge were recorded in the Records as following: arrowroot porridge, bean-leaf porridge, mung bean porridge, bean porridge, malt-rice porridge, oriental arborvitae seed porridge, crucian porridge, lotus seed porridge, adlay porridge, red bean porridge, welsh onion porridge, milk porridge, seashell porridge, ginko nut porridge, black sesame porridge, and mandarin porridge. Each porridge was used for the purpose of alleviating any disease that afflicted the king Yeongjo or his royal family members in relation with the ingredient herb's medicinal function. Conclusions : These porridges consumed by the king Yeongjo and his royal family members were used not only with a purpose of aiding their body's recovery from disease, but with the goal to actively curing them of ailments.

The purpose of this study is to design and implement an ontology-based retrieval system for the electronic records of universities and to compare its performance with the existing keyword-based retrieval system. We used OntoStudio 1.4 for implementing an ontology-based retrieval system, and the test collection consisted of the following: (1) 5,099 electronic records of the 'personnel management notification' created by Korea Maritime University, (2) 20 topics (10 short-topics and 10 long-topics), and (3) the relevant assessments were conducted by the group of human experts. 10 university staff participated in the experiment of keyword-based searching and used the same test collection as used in the experiment of ontology-based searching. The ontology-based retrieval system outperformed to the keyword-based retrieval system in terms of Recall and Precision, and the same results showed in the test of the short-topics and long-topics comparison.

Background: Liu-Yuan-Lei(陸淵雷) said that a medical record is both the marks of treatments and arts made by a excellent practitioner and the essence of TCM(Traditional Chinese Medicine). Jiang-Guan(江瓘) also said that reading medical records is one of the best way to develop one’s abilities If curing a disease without perfect clinical practice. Objectives: study on the special treatment about metrostaxis(崩漏) based on the Yi-Da-Gan(易大艮)’s medical records. and study on the differentiation of abnormal symptoms and signs about cold syndrome with pesudo-heat(眞寒假熱) based on the Yu-Chang(喩昌)'s medical records. Methods: First, read and study the medical records on metrostaxis(崩漏) of that made a profound study by Yi-Da-Gan(易大艮) and cold syndrome with pesudo-heat(眞寒假熱) of that made a profound study by Yu-Chang(喩昌). The next, write a paper on results and conclusions. Results and Conclusions: First, Yi-Da-Gan(易大艮) insist that must control the Qi under the blood disease conditions, taking the case of metrostaxis(崩漏). Secondly, we must study more on estimating the changing condition of Qi and the blood as time goes by, also study on the pulse and pulse condition in the four seasons(四時脈). Thirdly, Yu-Chang(喩昌) insist that be more careful in differentiation of symptoms and signs, taking the case of cold syndrome with pesudo-heat(眞寒假熱). Fourthly, Yu-Chang(喩昌) give an example that in condition of cold syndrome with pesudo-heat(眞寒假熱), sometimes, the pulse and pulse condition can be strong.

Available records of recent earthquakes show that near-field earthquakes have different characteristics than far-field earthquakes. In general, most of these unique characteristics of near-fault records can be attributed to their forward directivity. This phenomenon causes the records of ground motion normal to the fault to entail pulses with long periods in the velocity time history. The energy of the earthquake is almost accumulated in these pulses causing large displacements and, accordingly, severe damages in the building. Damage to structures caused by past earthquakes raises the need to assess the chance of future earthquake damage. There are a variety of methods to evaluate building seismic vulnerabilities with different computational cost and accuracy. In the meantime, fragility curves, which defines the possibility of structural damage as a function of ground motion characteristics and design parameters, are more common. These curves express the percentage of probability that the structural response will exceed the allowable performance limit at different seismic intensities. This study aims to obtain the fragility curve for low- and mid-rise structures of reinforced concrete moment frames by incremental dynamic analysis (IDA). These frames were exposed to an ensemble of 18 ground motions (nine records near-faults and nine records far-faults). Finally, after the analysis, their fragility curves are obtained using the limit states provided by HAZUS-MH 2.1. The result shows the near-fault earthquakes can drastically influence the fragility curves of the 6-story building while it has a minimal impact on those of the 3-story building.

Objectives : To analyze and understand the clear meaning of Nochae(勞瘵), which is used in the same meaning as tuberculosis in Korean medicine. Methods : Nochae was mainly investigated using the Korean medicine classic DB(https://mediclassics.kr). Records that clearly revealed the visual observation of Nochaechung(勞瘵蟲), the cause of Nochae, and those that do not were arranged in chronological order. It was also analyzed what modern diseases are similar to Nochae. Results : Records that Nochaechung can be observed visually through feces or vomiting suggested the possibility of ascariasis. Nochaechung, which has a shape similar to silkworms and causes symptoms such as coughing and hemoptysis similar to those of tuberculosis while parasitic on human, suggested the possibility of paragonimus westermani. Based on the record that it showed symptoms of coughing and hemoptysis along with chills, fever, and weight loss, Nochae might have been a disease such as pneumonia and lung cancer as well as tuberculosis. Records of women's bloating, weight loss, anorexia, and jaundice suggested that Nochae might have been a liver cirrhosis. Conclusions : Records that clearly reveal the visual observations of Nochaechung, suggested that Nochae was a parasitic disease such as ascariasis or paragonimiasis. Records that visual observation of Nochaechung was not clearly revealed, suggested that Nochae might have been diseases such as pneumonia, lung cancer, and liver cirrhosis in addition to tuberculosis.
