소프트웨어 개발 생산성과 질을 개선하기 위한 재사용 접근 방법들과 이들을 지원하는 라이브러리 시스템들이 개발되었다. 이들 시스템들은 재사용 컴포넌트들을 효과적으로 분류, 저장, 검색, 이해하기 위해 다양한 방법을 적용한다. 그러나, 라이브러리 시스템들의 수가 증가할 때, 시스템들을 분류하고 그들의 속성을 비교/분석하는 것은 어렵다. 본 논문에서는 재사용 라이브러리 시스템들을 분류하기 위한 기준을 제시한다. 제시된 기준들은 컴포넌트의 속성을 코드화 하는 패싯(facet)과 속성(attribute) 기반 분류 방법의 결합에 의해 정의된다. 제안된 분류 기준에 대한 유용성을 보이기 위해, 컴포넌트 분류 방법과 응용 도메인에 기초한 대표적인 라이브러리 시스템들이 선택되고, 제안된 기준에 의해 분류된다.

본 연구에서는 조기표를 활용하여 차세대 도서관 목록(NGC)에서 강조하는 검색 결과의 패싯 내비게이션 기능을 개선하고자 하였다. 조기표는 자료의 형식적인 측면이나 내용 측면을 체계적으로 나타내므로, 기존의 NGC에서 제공하고 있는 주요 패싯인 언어나 발행년도, 주제(대구분)와 같이 효과적인 패싯이 될 수 있다. 이에 한국십진분류법(KDC)을 적용한 서지레코드의 분류기호를 분석하여, 본표와 조기표의 합성 현황과 특징을 도출하였다. 그리고 이를 바탕으로 본표에 합성된 조기성 기호가 패싯 내비게이션 기능 강화에 활용될 수 있음을 제안하였다. 이 방안은 분류기호를 부여하기 위해 기존에 이루어져 왔던 주제 분석 과정의 산물을 재사용할 수 있다는 추가적인 이점도 가지고 있다.

우리 고전 문집에 나타난 용어로 작성된 디스크립터들을 분류하기 위해서 분류 체계를 개발하는 것이 이 연구의 목적이다. 고전 용어 시소러스의 분류 구조는 6개의 패싯으로 범주화를 시작하여 고전 분야의 지식을 근거로 연역적으로 분류 체계를 구조화하였다. 그리고 기존의 인문학 분야의 다른 시소러스들의 분류 체계와 비교하였고, 이러한 비교를 통해서 얻은 것은 고전 용어 분류 체계만이 갖는 여러 장점들 즉 패싯 기법을 적용한 장점 등을 확인할 수 있었다. 이러한 장점들로 인해서 범주 설정의 일관성과 분류 구조의 복잡성을 줄일 수 있었다. 또한 시대나 지역을 구분하기 위한 공통 구분을 독립적으로 설정하여 분류표의 크기를 줄일 수 있었다. 이 분류 체계는 디스크립터들을 배정하는 과정을 통해 보다 나은 분류 체계로 발전해 나갈 것이다.

The purpose of this paper is to examine the analytic-assembling(faceted analysis) methods applied in enumerative-hierarchical classification schemes. (mainly in KDC) The methods are summarized as follows : 1. For the enumerative-hierarchical classification schemes, in principle the subjects are divided into subdivisions by only one facet at the same level, and step by step. However some subjects, for example 'library and information science' 'education' and others in KDC, are divided into subdivisions by multiple facets at same level like Colon Classification. 2. Most of enumerative-hierarchical classification schemes have various kinds of auxiliary tables, such as standard subdivisions, areas, periods, and languages. Each of them is considered as foci by a facet applied to subdivide all kinds of subjects or some special subjects into lower level. 3. To classify the compound subjects with phase relation, KDC provides ready-made classification numbers or notes that says 'divide by 001-999'(whole subjects) of 'divide by xxx-xxx'(limited scope of subjects). The ready-made compound subjects, or subdividing by whole or limited scope of subjects are similar to representation of phase relation in Colon Classification. Yet these analytic-assembling methods in KDC are needed to be supplemented and amended. Subdividing methods for faceted analysis have to be unified through the whole schedule. The auxiliary tables should be enlarged and subdivided more specifically. And for representation of phase relation, the linking signs can be useful in KDC as well as UDC and other analytic-assembling classification schemes like Colon Classification.

Purpose: To propose a new comprehensive classification system of intraarticular calcaneal fracture based on CT images. Materials and methods: Fourty intraarticular calcaneal fractures which were treated operatively were evaluated retrospectively. We classified fracture types according to severity of comminution on the posterior facet and calcaneocuboid joint by CT images. And we evaluated postoperative results of each fracture types in terms of the quality of fixation and reduction by the postoperative plain radiograghs. Results: By the classification of the posterior facet, 18 cases were P-I, 15 were P-II, and 7 were P-III. Among the P-I cases, 7 were P-IA, 9 were P-IL, 1 was P-IM and 2 were P-IT. According to the classification of calcaneocuboid joint, II cases were C-I, 18 were C-II and 11 were C-III. Qualities of fixation were excellent in 27 cases (67.5%), fair in 9(22.5%) and poor in 4(10%). Qualities of reduction were excellent 23 cases(57.5%), fair in 11(27.5%) and poor in 6(15%). Conclusion: Our new classification system based on the CT images could provide informations about the fracture configuration and severity of comminution around calcaneocuboid joint as well as the posterior facet. And the high grade fractures such as type P-III are need to be taken care of fixation of articular surfaces.

본 연구는 유엔교육과학문화기구의 소장 자료 중 한국과 관련하여 수집한 기록물 1,136건(1950~1979년)을 대상으로 패싯 분류 체계를 설계한 것이다. 기록물의 제목과 색인어에서 명사 1,601개를 추출한 뒤 임시로 설정한 기본 범주를 기초로 하여 용어들을 분류하고 범주화하였고, 결과로 도출된 패싯 요소들을 10개의 기본 패싯과 38개의 하위 패싯으로 구조화하였다. 이를 바탕으로 각각의 패싯 요소를 정의하고 패싯별 분류기준을 제시하였으며, 패싯의 배열 순서를 지정하고 기호를 부여하였다.

Calcaneus is largest tarsal bone and the fracture of calcaneus is most common tarsal fractures. Calcaneal fractures are divided into extra-articular and intra-articular fractures. Intra-articular calcaneal fractures could be classified as tongue type and joint depression type using simple lateral radiograph (Essex-Lopresti classification), but Sanders suggested new classification according to involving the posterior facet of calcaneus using computed tomography. The involvement of posterior facet was revealed as more complicated than Essex-Lopresti classification. The principle purpose of treatment of calcaneal fractures are restoration of calcaneal height (B$\ddot{o}$hler angle), width, axis, anatomical reduction of joint and restoration of function through the stable fixation. Good visualization of joint and anatomical reduction could be achieved by extended lateral approach. But, skin problem could be occurred after of extended lateral approach.

This study was performed to investigate the factors related to tooth wear. For this study, 78 patients with temporomandibular disorders and 76 dental students without any signs and symptoms of temporomandibular disorders were selected as the patients group and as the normal group, respectively. Preferred chewing side, Angle's classification, lateral guidance pattern, head and shoulder posture were observed clinically. Electromyographic activity of anterior temporalis and masseter muscle were recorded with $BioEMG^{(R)}$ and occlusal status were recorded with $T-Scan^{(R)}$. Wear facet area of each tooth was measured from working model of upper arch corresponding to the occlusal status from T-Scan. Wear facet area were measured with planimeter in $mm^2$. Total area were divided into incisal, canine, posterior tooth area. Anterior wearfacet area was incisor area plus canine area, and unilateral area was anterior area plus posterior area. The data collected were analyzed by SAS statistical program and the results of this study were as follows: 1. There was no significant difference between the two groups in total werafacet area, and male subjects showed tendency to have larger area in the normal group but female subjects showed tendency vice versa. 2. There was no significant difference related to preferred chewing side and Angle's classification, however some difference was observed by lateral guidance pattern. Anterior wear facet area in subjects of canine guidance was the largest in the three subgroups. 3. Subjects with head tilting to right side had larger posterior and total area, and subjects with higher shoulder in right side had larger canine and anterior area than any other subgrous. 4. Electromyographic activity of masseter muscle was more correlated with wear facet area than anterior temporalis muscle, and tooth contact number and force were significantly correlated with wear facet area, but the most important factor affecting tooth attrition was age.

Purpose: The purpose of this study is to find out the correlation factors for prognosis of calcaneal fractures. Materials and Methods: 120 cases (feet) of calcaneal fractures, all of them followed up for more than 1 year after surgical procedures, consisted of 101 men (105 feet) and 13 women (15 feet) were reviewed retrospectively. The collected clinical data were as follows : injury mechanism, surgical procedures, time to procedure, time to work and the radiologic data: Bohler angle, heel width, displacement of posterior facet. AOFAS hindfoot score and VAS score were checked. With ANOVA test and multiple regression analysis, the data processed statistically. Results: According Sanders classification, type II was 37 cases (31%), type III 66 cases (55%), and type IV 17 cases (14%). On plane radiography, the Bohler angle improved to average 28.4 degree from 5.6 degree, and the displacement of posterior facet was corrected to average 1.2 mm. AOFAS hindfoot score was checked average 81.7 points postoperatively, and the meaningful difference existed between types of Sanders classification. The Bohler angle represented the outline of the calcaneus had the better correlation with the clinical outcome of calcaneal fractures rather than the anatomical reduction of the posterior facet did. And the width of calcaneus had good correlation with the clinical score. Conclusion: We should also concern about the outline of calcaneus, the width of calcaneus and the Bohler angle representing anatomical reduction, not only the acute reduction of the posterior facet.
