디지털 기술의 발달로 한글글꼴을 다루는 사용자가 증가하고 글꼴 선택의 기준 또한 다양해지면서 전통적인 형태를 벗어난 다양한 한글 글꼴들이 많이 개발되어 사용되고 있다. 그러나 현행 글꼴분류체계는 이러한 글꼴들을 비교분석하고 글꼴 사용의 가이드라인을 제시하기에 부족한 실정이다. 본 연구에서는 한글글꼴개발 및 활용을 지원하는 방안으로 글꼴분류체계의 다양화를 제시하고 다음과 같은 다각도의 분류기준을 제시한다. 첫째, 모임글자라는 한글글꼴의 근본적인 특징을 반영하고 한글 기계화에 큰 변수로 작용하는 한글의 구조에 기반한 글꼴구조분류, 둘째, 공감각적이고 멀티미디어적 정보전달이 일반화되어 가는 실정에 맞추어 감성 이미지어와 글꼴의 시각적 이미지를 연관시키는 글꼴이미지분류, 마지막으로 매체별로 가독성과 주시성 등을 고려하여 글꼴의 용도를 제시하는 글꼴용도분류를 제안한다. 멀티미디어 시대에 완성도 높고 다양한 글꼴의 개발과 문자정보의 부가가치를 높이는 적절하고도 효과적인 글꼴의 활용을 지원하기 위해서는 한글 글꼴의 특징과 사용환경에 기반하여 앞에 제시한 바와 같은 다각도의 분류체계를 세우고 이를 활용한 유기적인 글꼴데이터베이스를 구축하는데 적극적인 투자와 기술적인 지원이 필요하다. 이는 결과적으로 양질의 다양한 한글글꼴의 개발과 이의 활용도를 높일 수 있으리라 기대된다.

최근에는 대내외적 환경변화로 인하여 해양산업의 중요성은 높아지고 있다. 자원고갈, 기후변화, 북극해 개방 등으로 해양산업의 발전을 촉발하고 있다. IT와 융복합화가 요구되고 있는 신해양산업의 수요는 점차 높아지고 있다. 해양산업의 중요성에 대한 재인식이 필요한 시점이다. 따라서 국가차원의 해양산업 활동 수준을 평가하기 위해서는 해양산업에 대한 체계적인 분류체계가 구축되어야 한다.

Based on the supply status statistics of new renewable energy according to public obligation system, current status of overall application centered on solar heat, solar ray, and geothermal heat as energy sources that can be applied to buildings may be analyzed as follows. (1) After the public obligation system, the investment costs on the total construction costs by years were between 5.21% and 7.12%: they were 7.12% in 2004, where the system was initially implemented; and they were gradually declined from 2005 to 2011, 5.76% in average. The ratio of equipment investment per energy sources in the total construction costs was 5.9%, which was slightly more than the obliged ratio. The order of investment costs per energy source was solar ray, geothermal heat, and solar heat. (2) Among the 1,433 sites in the plan of new renewable energy installation based on the public obligation system, "for cultural & social use" was most in target institution, and facilities for education & research was most in use classification, followed by public working, culture & rally, and sports. The number of facilities applied according to the case for planning installation per use classification of the target institution was between 1.1 and 1.5, or 1.4 in average of energy source. Conclusively, the authors of this study investigated overall current status of new renewable energy supply from the analysis of statistic data, and it may be needed of further supplementation of various examinations by visiting investigation and interviews with practitioners based on classification of use of target institutions.

이 연구는 농학분야의 정보자료를 효율적으로 관리하기 위한 새로운 문헌분류표의 모형을 제시하기 위하여 시도된 것이다. 이를 위해 먼저 농학분야의 학문적 정의와 범위, 체계에 대하여 고찰하였고, 현재 사용되고 있는 KDC, DDC, UDC, NDC 등의 문헌분류법에서 농학분야 주제를 전개하고 있는 강목표에 대하여 비교 분석하였고 NAL의 AGRICOLA SCC를 살펴보았다. 그리고 이를 토대로 농학분야의 새로운 문헌분류표의 강목을 설정하여 전개하였다. 새로운 강목분류표의 전개는 농업과 관련한 인문사회학, 식물관련 농업, 동물관련 농업, 인간과의 관계성, 농업관련 보조분야 순으로 전개하였고, 강목표는 23개의 항목으로 설정되었다.

Several well-known soil classification charts, like made by Robertson(1986,1990), Olsen(1981), existed already. In Korea, Lee Sun-Jae(1997) made new classification chart based on Unified Soil Classification System with locality In this study, 6 classification charts were applied respective area. Even exact decision is impossible which one is correct, this study can give useful guideline.

Purpose: As the number of total knee arthroplasties (TKAs) increases, the incidence of femoral periprosthetic fractures after TKA is also increasing. This review aimed to suggest a new surgically oriented classification system for femoral periprosthetic fractures. Methods: We investigated the classifications, and current treatment trends for femoral periprosthetic fractures after TKA by means of a thorough review of the relevant literature. Results: Numerous studies reported good results of surgical treatment with modern fixatives including locking compression plates and retrograde intramedullary nails. However, few classifications of femoral periprosthetic fractures reflect the recent developments in surgical treatment. Conclusions: We recommend that surgical management be considered the first-line treatment for femoral periprosthetic fractures after TKA. Our new classification will help in deciding the surgical treatment option for femoral periprosthetic fractures after TKA.

The objective of this study was to investigate drug classification system in Korea and other developed countries. Laws and regulations of Korea regarding the system were retrieved from sources posted in Ministry of Government Legislation. We also reviewed previous research reports performed as part of government's effort to reform the system The system in the foreign countries was retrieved from the official homepage operated by each country's government. There have been two research funded by Korean government, which strongly suggested that the system should be reformed. However, we found that the system was never reformed and still effective. Drug classification system in US and most western countries consists of two categories, i.e., prescription drugs and non-prescription drugs except UK, which classifies into three categories: Prescription Only Medicines, Pharmacy Medicines, and General Sales List Medicines. Interestingly, in Japan, non-prescription drugs are further classified into three groups: Group 1, 2, and 3. Recently, Ministry of Health and Welfare (MOHW) in Korea proposed a plan to reclassify all the approved drugs according to purportedly rational and scientific criteria. However, the plan does not include reform of the existing laws and regulations, which appears that it is just one-time action rather than a sustainable administration backed up by law. Therefore, it is recommended that Korean MOHW take appropriate action on laws and regulations with regard to the system to meet global harmonization standard.

In this paper, we propose a new idea to evaluate the prediction accuracy of user's preference generated by memory-based collaborative filtering algorithm before prediction process in the recommender system. Our analysis results show the possibility of a pre-evaluation before the prediction process of users' preference of item's transaction on the web. Classification functions proposed in this study generate a user's rating pattern under certain conditions. In this research, we test whether classification functions select users who have lower prediction or higher prediction performance under collaborative filtering recommendation approach. The statistical test results will be based on the differences of the prediction accuracy of each user group which are classified by classification functions using the generative probability of specific rating. The characteristics of rating patterns of classified users will also be presented.

Background: The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) was developed to enhance chemical classification and hazard communication systems worldwide. However, some of the elements such as building blocks and data sources have the potential to cause "disharmony" to the GHS, particularly in its classification results. It is known that some countries have developed their own lists of classified chemicals in accordance with the GHS to "standardize" the classification results within their respective countries. However, the lists of classified chemicals may not be consistent among these countries. Method: In this study, the lists of classified chemicals developed by the European Union, Japan, Malaysia, and New Zealand were selected for comparison of classification results for carcinogenicity, germ cell mutagenicity, and reproductive toxicity. Results: The findings show that only 54%, 66%, and 37% of the classification results for each Carcinogen, Mutagen and Reproductive toxicants hazard classes, respectively are the same among the selected countries. This indicates a "moderate" level of consistency among the classified chemicals lists. Conclusion: By using classification results for the carcinogenicity, germ cell mutagenicity, and reproductive toxicity hazard classes, this study demonstrates the "disharmony" in the classification results among the selected countries. We believe that the findings of this study deserve the attention of the relevant international bodies.

토목공학분야의 도서는 최근 건설기술의 발전과 토목공학 적용분야의 확대로 인하여 방대한 양의 도서자료들이 발생하고 있다. 도서정보의 분류체계는 현재 각 도서관과 건설관련기관내의 자료실 등에서 서지, 논문 및 정기간행물 등의 분류체계로서 듀이십진분류법(Dewey Decimal Classification-DDC) 또는 한국십진분류법(Korean Decimal Classification-KDC)등을 사용하고 있다. 그러나 기존 분류체계의 토목공학 분류항들이 학문의 학술적, 기술적 분류와 일치하지 않는 점 등으로 효과적인 도서분류와 정보검색에 어려움이 있으므로, 토목공학분야의 도서분류체계를 보다 학문이론적 분류에 적합하도록 재구성할 필요가 있다. 본 연구에서는 국내외의 도서분류체계중 토목공학분야의 분류항들을 검토한 후, 적용상의 문제점 분석과 함께, 학술정보를 위한 학문적 분류와 실무자료검색을 위한 기술적 분류의 연계성을 갖추어, 요구되는 정보를 보다 편리하게 검색할 수 있는 새로운 토목공학분야 도서분류의 류, 강 분류체계를 제시하고 있다. 제시된 분류체계는 건설 기술정보분류체계의 구성시에 시설물 정보분류항으로 활용될 수 있으며, 한국십진분류법의 개 ㅍ\ulcorner토목공학분야 분류코드로 참조될 수 있을 것이다.
