The purpose of this study is to consider how Kim Young-hun approached and treated diseases caused by seven emotions using Cheonggang medical records database. Kim Young-hun often related seven emotions with qi, phlegm, fire and depressions of these three and with the loss of dignity (脫營). Records of seven emotions were especially concentrated in the 1950s, and it seems to have been influenced by the Korean war. The prescriptions which Kim used frequently were introduced as modified 六鬱湯. Analyzing the medicinal herbs Kim used, it was estimated that Kim would have applied "allevating phlegm and regulating qi" as the principle of the treatment of the seven emotions using 二陳湯 and Cyperus(香附子) with some adjustment of 利濕藥, 疏導藥, 淸熱藥, and 四物湯.

Recently, the renewable energy resources play an important role as an energy resources of future due to an environmental pollution and lack of resources and so on. The development and diffusion of information systems related to renewable energy resources have been driven actively abroad. However, at domestic an efficient history management for renewable energy resource data and web retrieve service are not provided. Therefore, in this paper, we propose a history data management system for the renewable energy resources, which stores and manages vast history information of renewable energy resource data systematically. This system collects renewable energy resource data in the outside observation system and stores them in the history database. The stored Information is retrieved through the history query process and can be provided in various forms - table, graph, chart and counter line, etc. - on the internet. Especially, the proposed system manages the history data in real-time so the latest information is always provided to the users through the web interface.

Objectives : In evaluating a child with enuresis, an organized approach to the history leads to a working diagnosis and an appropriate treatment plan. but, there's no study about history taking in enuretic children. This article was undertaken to evaluate the enuretic child exactly and to study nocturnal enuresis systematically. Methods : It was conducted a computerized literature search in following database: Medline (via Pubmed), NDSL, EBSCO. Korean articles via oriental pediatric association homepage, KISS. Key words to search were 'nocturnal enuresis', 'bedwetting', 'enuresis', 'incontinence', 'management', 'evaluation', 'assessment', 'questionnaire', 'guideline', 'voiding dysfunction'. Results : Questions are grouped in eight categories: primary history(sex, age, height, weight), family history, enuresis history(primary/secondary, frequency, time of enuresis, nocturia), voiding history(average number, frequency, pattern, volume, posture, daytime enuresis), medical history, constipation/encopresis, sleep(OSA). Conclusion : A careful, complete history taking will help to plan treatment properly and to study.

Objectives : Treatment method using drugs has already been used in Korean medicine for a long time. Moreover, database has been developed and utilized for more efficient management of the treatments that use drugs. Most of such database related to knowledge on drugs is composed of origin, efficacy, temperament, ingredients and examples of application of the standardized drugs. Communication with knowledge information in other specialized areas is also accomplished by using the efficacies and ingredients with the drugs. In this study, we aimed to make data structure of the terminologies that represent the manufacturing process of herbs. However, in spite of the fact that the manufacturing process of the drugs imparts effect on their efficacies and ingredients, details of the manufacturing processes are quite limited to simple text sentences, thereby resulting in substantially lower level of utilization and difficulties in systematic researches on various factors included in the manufacturing processes in comparison to other knowledge on drugs. Methods : This Study extracted the factors necessary in the development of database by executing morphological analysis of the manufacturing process of herbs. Results : The factors are 'Order', 'Act', 'Raw material', 'Tools', 'Supporting materials', 'Intensity', 'Duration Time', 'Interval', 'Focus', 'Repetition Number', 'Untill'. We were able to tell the difference of the manufacturing process with a simple structured query language and the factors. Conclusions : Morphological analysis of medicinal herbs manufacturing Process contributes to standardization with information of the manufacturing process. And it helps to creates a quality management system through the Database.

The modification of digital maps because of creation, extinction, and change of topology can be expressed by change of information. But according to complication of society, topology of digital maps and relation with another objects is more complicated. We carry out partial update using as-built drawings to reflect in digital maps efficiently with maintaining accuracy and update. This supplement a weak point of partial update without field surveying. But unlike creation and extinction of file with information or of entire database, when each object is changed, added problem will come like change of raw data and of updating date. So it is necessary that history data about creation, change and extinction of spatial data and attribute data have to be chosen and managed. In this study, we analyze operations of updating system of digital map using as-built drawings, and suggest the history database system.

Currently, there are about 20,000 or so known ancient medical texts from the East Asian medical traditions. Although the most famous texts are widely known, many texts still exist only as original manuscripts. We are interested exploring these texts to uncover the potential benefits of their therapeutic knowledge. This study aims to develop a database program that automatically converts the treatment skills described in the text version into a more structured version. In the previous study, our team analyzed patterns in the way that treatment skills are described and then tried to design a database program algorithm that identified every meaningful keyword used to describe treatment skills and put that word in the right cell of a structured table. This study continues the development of this program. East Asian medical herbal treatment information is broken down into 4 elements: the first one is the name or title of treatment skills, and the second is the symptoms to which the treatment is applied, the third is ingredients used, the fourth is how information is processed and the indications taken. This study presents the algorithm's principles on how to analyze and structure the fourth element, the processing of information and taking of indications, which is described in a form of ancient natural language.

Recently the necessity of time history analyses is increasing for the seismic analyses of a structure, and the seismic design provisions of IBC2003, ASCE and KBC2005 require the use of a minimum of seven earthquake records for the time history analyses. Earthquake records for the time history analyses could be selected from the database of the field-measured earthquake records having similar site conditions with the designed site, or from simulated sites satisfying the design spectrum. However, in this study seven earthquake records were generated using 50 earthquake records, classified as records measured at the rock, in the database of the Pacific Earthquake Research Center (PEER). Seven earthquake records were first selected by the least squares fitting method comparing the scaling factored response spectra with the specified design spectrum, and a family of seven artificial time history earthquake records was ultimately generated by multiplying scaling factors, which were calculated by the least squares fitting method and the SRSS averaging method, to the corresponding selected earthquake records.
