복합명사는 둘 이상의 말이 결합된 명사를 말하며 문장에서 하나의 단어로 간주된다, 그러나 맞춤법 및 띄어쓰기 검사나 정보검색의 색인어 추출, 기계번역의 미등록어 추정 등의 분야에서는 복합명사를 구성하는 개별 단어를 확인할 필요가 있다. 이 과정을 복합명사 분해라고 한다. 복합명사를 분해하는 방법으로 크게 규칙 기반 방법, 통계 기반 방법 등이 있으며 본 논문에서는 규칙을 기반으로 최소한의 통계 정보를 이용하는 방법을 제안한다. 본 논문은 4개의 분해 규칙을 적용하여 분해 후보를 생성하고 분해 후보들 중에 우선순위를 정하여 최적 후보를 선택하는 방법을 제안한다. 기본 단어(명사)로 트라이(trie)를 구축하고 구축된 트라이를 이용하여 양방향 최장일치를 적용하고 음절 쌍의 통계정보를 이용해서 모호성을 제거한다. 성능을 평가하기 위해 70,000여 개의 명사 사전과 음절 쌍 통계정보를 구축하였고, 이를 바탕으로 복합명사를 분해하였으며, 분해 정확도는 단어 구성비를 반영하면 96.63%이다. 제안된 복합명사 분해 방법은 최소한의 데이터를 이용하여 복합명사 분해를 수행하였으며 트라이 자료구조를 사용해서 사전의 크기를 줄이고 사전의 검색 속도를 개선하였다. 그 결과로 임베디드 시스템과 같은 소형 기기의 환경에 적합한 복합명사 분해 시스템을 구현할 수 있었다.

Forty-four females with normal temporomandibular joint were compared with fifty-one females with abnormal temporomandibular joint. An orthodontic study model and lateral cephalometric radiographic were used to investigate the relationship between TMD group and non-TMD group in long face patterns. The result were followed that ; 1. There were no significant in overbite and overjet amount. 2. A mandibular 1'st molar inclination and height to the mandibualr plane were more mesial inclined in TMD groups. 3. The functional factors, which were craniocervical posture , tongue posture and hyoid bone position, were no significant.

In this paper, an improved two-step P2P traffic classification scheme is proposed to overcome the limitations of the existing methods. The first step is a signature-based classifier at the packet-level. The second step consists of pattern heuristic rules and a statistics-based classifier at the flow-level. With pattern heuristic rules, the accuracy can be improved and the amount of traffic to be classified by statistics-based classifier can be reduced. Based on the analysis of different decision tree algorithms, the statistics-based classifier is implemented with REPTree. In addition, the ensemble algorithm is used to improve the performance of statistics-based classifier Through the verification with the real datasets, it is shown that our hybrid scheme provides higher accuracy and lower overhead compared to other existing schemes.

Followed by government authorized data that Ministry of Education submitted, safety accident at school has been increased year by year. Safety accident occurred 33,834 in 2005, 29,955 in 2004, and 22,722 in 2003. It shows that it has been increased about 12.9% from 2004 and 48.9% in 2003. Level of student's development, students are at the point of not having enough judgement and ability to adapt at emergency situation. They are learned about safety by education and management by teachers but teachers will get heavy burden and anxiety if government doesn't provide more improved support and restraint. On this situation, educational authority can be attacked and it legally charged by nation, owned property can be loss or prosecution can be occurred. Also school safety accident which occurs in these days is working as an negative insecurity element that teachers cannot concentrate on the education.

Fire trends in Korea, Japan, and the United States were analyzed in this paper. The number of fires in the U.S. tends to decrease greatly from 3,264,500 cases in 1977 to 1,687,500 in 2002. There have been an estimated 60,000 fires annually more than 20 years in Japan, at the peak of 73,072 cases in 1973. In case of Korea, 5438 fires occurred in 1980. However, fires increased rapidly up to 36,169 cases in 2001 and 31,372 cases in 2003. In addition, fire statistics processing methods and fire statistics reports were analyzed. The result was that Korea was behind most of the three countries. Therefore I confirmed that we need not only to study systematical processing methods of fire statistics in order to get confidence on those like accurate estimating fire data analysis, but also to publish variable and specific reports on fires for the purpose of analyzing fire data.

Much of the process in Social Science Research can be expedited with use of an automation systems that can lead to research efficiency and dramatic improvement of the research process. This study proposes use of a social science research automation system based on the cloud, which generates questionnaires, supports data collection, and intuitively processes statistical analyses of the data collected. The Cloud-based Social Science Research Automation System is developed with GNU/GPL-based open source software. We also integrate R for statistical computing to enable advanced statistical analyses such as PLS structural equation modeling, mediate effect analysis, compare between groups, and complete general statistics. The Cloud-based Social Science Research Automation system developed in this study is expected to play an important role in improving the social science research process and in performing the social science studies efficiently.

This study was conducted on men and women in their teens and 50s living in Seoul, Incheon and Gyeonggi-do to find out the relevance between demographic characteristics of lifestyle clusters and the characteristics of beauty salon use. To analyze the data of a total of 522 people collected, statistical processing was performed with analysis of frequency, analysis of factor, analysis of reliability, analysis of cluster, analysis of variance and analysis of cross. As a result, lifestyle group types were classified as fashion and social focus types, family-oriented types, and family-free types. These types were highly related to age, final education, and marital status among demographic characteristics, and were also found to be highly relevant to the characteristics of beauty salon use, such as beauty salon location and frequently used beauty services. The results of this study are thought to be the basic data that can be used for beauty salon marketing.

This study examined the impact of departmental trust on departmental development and academic performance in the department affiliated with physical eduction. Furthermore, it investigated the differences of departmental development and departmental trust by gender and school year of the students. Data were analyzed from 313 students in the department affiliated with Physical Education from 6 institutions of a 4-year university located in Seoul, Gyeonggi-do, Incheon, and ChungChong-do. For the research questions, simple linear regression model and two-way multivariate analysis of variance were analyzed. Results indicated that departmental trust had a positive effect on departmental development. But, departmental trust statistically had no effect on academic performance. Sophomore and junior in departmental development were higher than senior. Junior in departmental trust was higher than senior. There was no statistically difference in departmental development and departmental trust by gender.
