While science and technology information service portals and heterogeneous databases produced in Korea and other countries are integrated, methods of connecting the unique classification systems applied to each database have been studied. Results of technologists' research, such as, journal articles, patent specifications, and research reports, are organically related to each other. In this case, if the most basic and meaningful classification systems are not connected, it is difficult to achieve interoperability of the information and thus not easy to implement meaningful science technology information services through information convergence. This study aims to address the aforementioned issue by analyzing mapping systems between classification systems in order to design a structure to connect a variety of classification systems used in the academic information database of the Korea Institute of Science and Technology Information, which provides science and technology information portal service. This study also aims to design a mapping system for the classification systems to be applied to actual science and technology information services and information management systems.

IBC와 KBC의 지반분류는 ft-kips 단위체계를 기본으로 하고, 지반종류를 단일 지반특성값이 아닌 지반특성값 범위로 규정하여 지반종류에 따른 전단파속도와 지반계수들 간의 불명확한 관계 때문에 지반계수의 선형보간이 쉽지 않다. 또한, KBC의 지반분류에서 각 지반종류에 대한 지반특성값 범위가 너무 넓어서 구조기술자들이 다양한 지반의 실제적인 지반계수를 추정하는데 어려움을 격고 있다. 이 연구에서는 SI 단위체계를 고려한 새로운 지반분류체계를KBC등 차세대 내진설계기준을 위해 제안하였고, 제안된 새로운 지반분류에 따라 지반계수들의 선형보간 가능성을 검토하기 위해 $F_{a},\;F_{v}$, 지반계수들의 비교에 관한 연구를 수행하였다. 연구결과에 의하면, SI 단위체계와 얕게 묻힌기초 밑 30m 지반의 지반특성을 고려한 새로 제안한 지반분류체계를 이용하는 것이 지반계수의 선형보간을 위해서 보다 합리적이고, 설계스펙트럼 가속도계수의 선형보간도 각 지반을 대표하는 전단파속도에 따라 지반계수를 규정함으로써 보다 합리적으로 수행할 수 있다. 연구결과에 따라 KBC 내진설계기준을 위한 새로운 지반분류체계와 선형보간이 가능한 설계스펙트럼 가속도 계수를 제안하였다.

Success in the excavation of foundations is commonly known as being very important in asserting stability. Furthermore, when the subjected formation is rocky and the use of explores is required, the demands of successful blasting are multiplied. The quick and correct estimation of excavation's characteristics may help the design of building structures, increasing their safety. The present paper proposes a new classification system which connects blastability and rock mass quality. This new system primarily concerns poor and friable rock mass, heavily broken with mixture of angular and rounded rock pieces. However, it should concern medium and good quality rock mass. The Blastability Quality System (BQS) can be an easy and widely - used tool as it is a quick calculator for blastability index (BI) and rock mass quality. Taking into account the research calculations and the parameters of BQS, what has been at question in this paper is the effect of BI magnitude on a geological structure.

Objectives : To establish a well organized and systematic oriental medicine classification of headache, the western and oriental medicine diagnosis and treatment systems of headache were reviewed. Methods : The history and development process of western medicine classification of headache were studied. A literature review of oriental medicine classification of headache was done. The characters of each classification systems were assessed. Results : In western medicine, many international societies concerning headache have been established. Through these societies, a classification of headache which can be used by both researchers and practitioners has been suggested. And the suggested classification system is highly recommended to be used in studies in order to increase utilization. As data is accumulated, new versions of the classification system were updated. But in the case of oriental medicine, various classification systems of headache are presented in numerous literatures. But the effort to unify and systemize the oriental medicine headache classification has been in lack. Conclusions : Establishment and utilization of a standardized oriental medicine headache classification system, based on various classifications and detailed descriptions is needed.

This study was attempted to help in explore new direction about Clinical Classification System of the pediatric patients visiting emergency center. Data were collected from 276 patients who visited emergency center of E University Hospital during 3 months period form March 1, to May 31, 1999. The results were as follows: 1. Distribution of pediatric patients according to Clinical Classification System, class I(59.9%) topped followed by class II(23.9%), class III(14.1%), class IV(2.0%). Average score of pediatric patients according to Clinical Classification System showed class I.00, class II .02, class III .05, class IV .07. and total mean score of items lowed averaged .01. 2. With the resepect to the Clinical Classification System according to the pediatric patients visiting emergency center, there were stastically significant difference in visiting time($x^2=27.839$, P=.023), experience of admission($x^2=11.365$, p=.010), disease classification($x^2=89.998$, p=.000), state of airway patency($x^2=18.781$, p=.000), consciousness level($x^2=59.774$, p=.000), period of symptom manifestation($x^2=34.112$, p=.000), pediatric patients protector's thinking about pediatric patients state($x^2=49.998$, p=.000), treatment outcome($x^2=72.278$, p=.000), duration of stay at emergency center($x^2=103.062$, p=.000). 3. There were significant correlation between the state of pediatric patients and Clinical Classification System(r=.530, p=.000).

본 연구는 문헌분류표를 바탕으로 음식문화 분야와 한식을 고찰하여 음식문화의 다양한 주제를 보다 더 효과적으로 분류할 수 있도록 DDC의 개선 방향을 제시하였다. 이를 위해 동서양의 대표적인 분류 체계인 DDC, UDC, LCC, KDC, NDC, 중국도서관도서분류법을 대상으로 식생활 풍습, 식사 예절, 영양과 식이, 식품과 음료, 식단과 상차림, 음료 기술, 식품 공학으로 나누어 음식문화와 관련된 항목들을 비교분석하였다. 분석 결과, 6개 분류표의 한식에 대한 분류 항목은 거의 없었으며 앞으로 한국 고유의 음식과 상차림 등이 분류표에 반영될 필요성을 확인하였다. 분류표에 새로운 분류 항목이나 주기의 추가를 위해서는 문헌적 타당성을 가져야 하므로 다양한 한식에 관한 조리법이나 간행물을 발간하고 이를 전 세계에 알려야 할 것이다.

Recently, there is greater demand for stable supply of electric power as higher level of our living. It becomes the important problem that the cause of fault in power system is found out in early stage, if once it occurs. In this respect, accurate classification of arcing faults in power systems is vitally important. This paper presents a new classification method for arcing faults in power system. To obtain data of various faults including high impedance fault(HIF) and low impedance fault(LIF), HIF model with the ZnO arrester is adopted and implemented within the overall transmission system model based on the electromagnetic transients program(EMTP). Results of phase plane trajectory if Clarke modal transformation using postfault current and voltage are utilized to classify types of arcing faults. The performance of the proposed method is tested on a typical 154 kV korean transmission system under various fault conditions. As can be seen from results, phase plane trajectory of postfault current should be combined with that of o component from Clarke modal transformation to give reliability of clear fault classification. Thus the proposed method can classify arcing faults including LIFs and HIFs accurately in power systems.

Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is a primary liver cancer (PLC) with both hepatocytic and cholangiocytic phenotypes. Recently, the World Health Organization (WHO) updated its histological classification system for cHCC-CCA. Compared to the previous WHO histological classification system, the new version no longer recognizes subtypes of cHCC-CCA with stem cell features. Furthermore, some of these cHCC-CCA subtypes with stem cell features have been recategorized as either hepatocellular carcinomas (HCCs) or intrahepatic cholangiocarcinomas (ICCs). Additionally, distinctive diagnostic terms for intermediate cell carcinomas and cholangiolocarcinomas (previous cholangiolocellular carcinoma subtype) are now recommended. It is important for radiologists to understand these changes because of its potential impact on the imaging-based diagnosis of HCC, particularly because cHCC-CCAs frequently manifest as HCC mimickers, ICC mimickers, or as indeterminate on imaging studies. Therefore, in this review, we introduce the 2019 WHO classification system for cHCC-CCA, illustrate important imaging features characteristic of its subtypes, discuss the impact on imaging-based diagnosis of HCC, and address other important considerations.
