The international standards, ISO 15489 and Family Code, recommend using functional classification method both in public and private organizations. In this study made a comparative analysis of the details of classification systems through case studies on records classification systems of a total of seven comprehensive construction companies in Korea including three large corporations and four small and medium-size businesses. Findings of this study suggester the direction of developing construction records classification system and its methodology. By summarizing classification standards derived from these case studies, key construction records classification standards were presented.

This study investigated general problems concerning the social welfare field in the KDC 6th edition based comparative analysis academic characteristics and classification system, and suggested on some ideas for the improvements of them. Results of the study are summarized as follows. First, a main field of the social welfare is generally divided into a general social welfare, social works, and social welfare services to special classes and groups including people with disabilities, young people, aged, women, and families. Second, I analyzed on social welfare from the collection database at the National Library of Korea. Based on analysis of the data. the keyword frequency of social welfare policy and management, pensions, care services, and support works for the underprivileged was relatively high. Third, modified classification of items was basically performed through the academic characteristics of the social welfare and the keyword analysis, and maintaining the existing KDC classification system caused less confusion as much as possible.

The amount of incoming e-mails is increasing rapidly due to the wide usage of Internet. Therefore, it is more required to classify incoming e-mails efficiently and accurately. Currently, the e-mail classification techniques are focused on two way classification to filter spam mails from normal ones based mainly on Bayesian and Rule. The clustering method has been used for the multi-way classification of e-mails. But it has a disadvantage of low accuracy of classification. In this paper, we propose a novel multi-way e-mail classification method that uses PCA for automatic category generation and dynamic category hierarchy for high accuracy of classification. It classifies a huge amount of incoming e-mails automatically, efficiently, and accurately.

The purpose of this study was to find out taxonomic characteristics of objectives infered from questions of summative evaluation by analyzing those objectives with Bloom's revised taxonomy of educational objectives. 1,711 questions of midterm and final examinations collected from 25 middle schools were analyzed to classify objective of each question. The major findings of the study were as follows: first, from the analysis of objectives in the knowledge dimension, the assessment of factual knowledge was most prevailing(67.6%) in the biology summative evaluation. In the cognitive process dimension, memory assessment was most dominant(76.1%). Thus, the main objectives of evaluation leaned toward particular classes in the Bloom's revised taxonomy, which was different from the findings of earlier studies on the weights of evaluation areas. Second, the level of the objectives should be determined in consideration of the grade of middle schoolers, as their cognitive level improves with grade. In fact, however, there was no difference among three grades in characteristics of objective taxonomy.

RRecords management has focused largely on public records in south korea with a relatively low progress in the collection and management of private records with the enactment of Public Records Act in 1999. This study set out to categorize the records of the Coalition for Democratic Reunification and the People's Movement(DRPM) and develop them into a group collection. For this study, literature reviews, analysis and reorganization of records content, development of a classification system, and expert evaluation were carried out. The findings of this study will contribute to greater efficiency in the search of records about the DRPM by developing a classification system to recategorize its records of various sources and enable their easy access and utilization in a digital archive. In addition, the basic structure of producer-oriented classification can be suggested as an example of the organization of a group collection.

The high-tech industry, a leader in the national economy, has a larger investment cost compared to general buildings, a shorter construction period, and requires continuous investment. Therefore, accurate construction cost prediction and quick decision-making are important factors for efficient cost and process management. Overseas, the construction information classification system has been standardized since 1980 and has been continuously developed, improving construction productivity by systematically collecting and utilizing project life cycle information. At domestic construction sites, attempts have been made to standardize the classification system of construction information, but it is difficult to achieve continuous standardization and systematization due to the absence of a standardization body and differences in cost and process management methods for each construction company. Particular, in the case of the high-tech industry, the standardization and systematization level of the construction information classification system for high-tech facility construction is very low due to problems such as large scale, numerous types of work, complex construction and security. Therefore, the purpose of this study is to construct a construction information classification system suitable for high-tech facility construction through collection, classification, and analysis of related project data constructed in Korea. Based on the WBS (Work Breakdown Structure) and CBS (Cost Breakdown Structure) classified and analyzed through this study, a code system through hierarchical classification was proposed, and the cost model of buildings by linking WBS and CBS was three-dimensionalized and the utilized method was presented. Through this, an information classification system based on inter-relationships can be developed beyond the one-way tree structure, which is a general construction information classification system, and effects such as shortening of construction period and cost reduction will be maximized.

형식승인제도는 몇년 전까지만 해도 전기통신 단말장치에 대한 정부의 고유한 통제와 권한의 영역이라고 생각할 만큼 규제 일변도의 정책 차원으로 다루어졌으나, 최근 통신시장 개방화 및 세계화 등과 같은 국제적인 통신환경을 반영한 단말장치의 통신망 접속 자유화가 실현됨에 따라 새로운 대내.외의 경쟁적 환경 위에서 운영하게 되었다. 특히, 최근에 각국은 다른 국가와의 형식승인 상호인정을 고려하면서 전기통신기술의 급격한 발전에 능동적 및 포괄적으로 대처하기 위한 전기통신 단말장치의 형식승인 적용 분류체계를 재조명하는 흐름을 보이고 있다. 이에, 본 고에서는 선진국의 형식승인 적용 대상 단말장치의 범위와 기능 및 용도별의 분류체계를 분석하여 항목별로 선정되고 있는 국내 형식승인 적용 대상 단말 장치의 분류체계를 선진국 수준의 기능 및 용도별로 개선하기 위한 방향을 모색해 보았다.
