이 연구는 MRF(Master Reference File)를 바탕으로 2005년에 영국의 BSI(British Standards Institution) 에서 인쇄 형태로 출판한 UDC(Universal Decimal Classification)의 표준판(Standard edition)을 대상으로 그 성립배경과 구조적 특성을 분석하고, 한국어 간략판과 비교하였다. UDC는 다른 십진식분류표에 대비하여 독특한 구조적 특성이 있으며, 한국어 간략판과 비교하여 볼 때 국제적 보편성을 더욱 강화하였고, 보조표를 통한 조합의 방식이 더욱 확대되었다. 이 연구를 바탕으로 앞으로의 KDC(Korean Decimal Classification)의 개정에 있어서 참고가 될 만한 KDC MRF 데이터베이스 개발과 보조표의 개선과 새로운 신설을 제언하였다.

As a means of improving Korean Soil Classification System, we have reviewed Australian Soil Classification System by comparing Soil Taxonomy and FAO/WRB Classification System. Australian Soil Classification System is composed of 14 of Order, 87 of Sub-order, 556 of Great-group, 2,451 of Sub-group, and 7,276 of Family. Interestingly, soil order has the Anthroposols which is not classified with Soil Taxonomy, and the classification for some of soils is based on soil texture abruption horizon and soil structure. Seven of 14 soil orders are classified with an old version based on soil color rather than morphological characteristics. The distribution scale of Australian soil order is the largest in Tenosols, and followed by Kandosols, Rudosols, Sodosols and Vertisols in Australia.

High-resolution satellite images offer abundance information of the earth surface for remote sensing applications. The information includes geometry, texture and attribute characteristic. The pixel-based image classification can't satisfy high-resolution satellite image's classification precision and produce large data redundancy. Object-oriented information extraction not only depends on spectrum character, but also use geometry and structure information. It can provide an accessible and truly revolutionary approach. Using Beijing Spot 5 high-resolution image and object-oriented classification with the eCognition software, we accomplish the cultures' precise classification. The test areas have five culture types including water, vegetation, road, building and bare lands. We use nearest neighbor classification and appraise the overall classification accuracy. The average of five species reaches 0.90. All of maximum is 1. The standard deviation is less than 0.11. The overall accuracy can reach $95.47\%.$ This method offers a new technology for high-resolution satellite images' available applications in remote sensing culture classification.

This paper considers a problem of classification of variable stars based on functional data analysis. For a better understanding of galaxy structure and stellar evolution, various approaches for classification of variable stars have been studied. Several features that explain the characteristics of variable stars (such as color index, amplitude, period, and Fourier coefficients) were usually used to classify variable stars. Excluding other factors but focusing only on the curve shapes of variable stars, Deb and Singh (2009) proposed a classification procedure using multivariate principal component analysis. However, this approach is limited to accommodate some features of the light curve data that are unequally spaced in the phase domain and have some functional properties. In this paper, we propose a light curve estimation method that is suitable for functional data analysis, and provide a classification procedure for variable stars that combined the features of a light curve with existing functional data analysis methods. To evaluate its practical applicability, we apply the proposed classification procedure to the data sets of variable stars from the project STellar Astrophysics and Research on Exoplanets (STARE).

Background: Although the zygomatic arch is an important structure determining facial prominence and width, no consensus exists regarding the classification of isolated zygomatic arch fractures, and the literature on this topic is scarce. To date, five papers have subdivided zygomatic arch fractures; however, only one of those proposed classifications includes the injury vector, although the injury vector is one of the most important factors to consider in fracture cases. Furthermore, the only classification that does include the injury vector is too complicated to be suitable for daily practice. In addition, the existing classifications are clinically limited because they do not consider greenstick fractures, nondisplaced fractures, or coronoid impingement. In the present study, we present a rearrangement of the previously published classifications and propose a modified classification of isolated zygomatic arch fractures that maximizes the advantages and overcomes the disadvantages of previous classification systems. Methods: The classification criteria for isolated zygomatic arch fractures described in five previous studies were analyzed, rearranged, and supplemented to generate a modified classification. The medical records, radiographs, and facial bone computed tomography findings of 134 patients with isolated zygomatic arch fractures who visited our hospital between January 2010 and December 2019 were also retrospectively analyzed. Results: We analyzed major classification criteria (displacement, the force vector of the injury, V-shaped fracture, and coronoid impingement) for isolated zygomatic arch fracture from the five previous studies and developed a modified classification by subdividing zygomatic arch fractures. We applied the modified classification to cases of isolated zygomatic arch fracture at our hospital. The surgery rate and injury severity differed significantly from fracture types I to VI. Conclusion: Using our modified classification, we could determine that both the injury force and the injury vector meaningfully influenced the surgery rate and the severity of the injuries.

본 논문은 디지털 전시를 효과적으로 분석하기 위해서 디지털 전시에 적합한 분류와 분석 기준을 제시하고자 한다. 디지털 전시 분류와 분석에 대한 선행 연구를 통해 새로운 기준의 필요성을 제시하여, 새롭게 등장하는 디지털 전시의 개념과 형식의 변화에 쉽게 적용할 수 있는 분석 기준을 정립한다. 디지털 전시는 상호작용적인 스토리텔링을 활용한 전시 기획과 형식에 의해서 자연 발생하는 관객 참여에 대한 요소를 고려해야 한다. 기존 디지털 전시 공간에 대한 분류와 분석은 키워드 중심의 개념적 분류를 하고 있다. 이는 전시와 작품을 분류하는 과정에서 전통적인 방법론이 적용되었기 때문이다. 하지만 디지털 전시에서 전시공간, 작품, 관람객 간의 상호작용적 관계는 매우 중요하다. 따라서 디지털 전시에서 작품과 관객 간에 이루어지는 수행적인 분류가 필요하다. 그래서 관객이 느낀 것을 토대로 전시 분류에 직간접적으로 참여하는 방식이 고려되어야 한다. 본 논문에서는 전시의 분류와 구성에 대한 해석을 위해서 벤야민의 주장에 따라 관객과의 상호작용성과 밀접한 관객의 감각체험 분류와 현재화를 참조하고, 채트먼의 서사구조에 기반을 둔 미술 전시 내러티브 구조에 따라 디지털 전시에 대한 분석 기준을 제시한다. 이러한 분류 방법론이 전시정보를 관람객에게 쉽게 이해할 수 있는 방식으로 제공하고, 나아가서는 디지털 전시의 확장성과 접근성을 확보하는 선행 연구가 될 것이다.
