보통의 CPU 처럼 명령어 기반으로 정규표현식 패턴 매칭을 수행하는 정규표현식 프로세서가 최근에 연구되었다. 이들 중 REMPc만이 문자 클래스 처리를 위한 기능을 제공한다. 본 논문에서는 정규표현식에서 사용 빈도가 높은 문자 클래스들에 대해서 명령어의 오퍼랜드 필드에 비트맵 방식으로 나타내고, 하드 배선 방식으로 이 문자 클래스에 대한 매칭을 수행하여 효율적인 문자클래스 매칭을 수행하는 구조를 제안한다. 제안한 방법을 사용하면 Snort 규칙의 문자 클래스에 대해서 대부분의 문자 클래스를 명령어의 한 오퍼런드 또는 한 명령어로 나타낼 수 있다. 이처럼 REMPc에 비해서 적은 수의 명령어를 사용하므로 효율적인 문자 클래스 매칭을 할 수 있다.

This study aimed to investigate whether protestant religious facilities are maintained appropriately for people and regular inspections are conducted. As a study method, survey and site investigation were conducted. The survey questionnaire aimed to know the perception of users or responsible persons about safety management and current status of safety management systems while the site investigation aimed to inspect structural conditions by a visual inspection such as proper installation of fire protection equipment and whether regular inspection were conducted. It was found, through the inspection of the current safety management status, that the safety management related persons did not know which parts and how much they manage incorrectly, and did not know the follow-up actions in case of accidents. Therefore, it is essentially required to assign a proper person to the facilities for safety management and to have safety consciousness education. Furthermore, although more than 80% of the surveyed subjects responded that they were familiar with the way to use safety management related facilities and overall instructions, the respondent were concerned about the correspondent training for emergent circumstances.

This study was undertaken to investigate the causal perceptions and health seeking behaviors of Rheumatoid arthritis patients, define and understand the typology, and find the relationship between causal perceptions and health seeking behavioral types. There were six types(Physical Fatigue, Dispensation of Nature, Causality to Environment, Conscience of Guilty, Rationally perceiving, Psychological Stress) of subjective opinion about Causal Perceptions of Rheumatoid Arthritis Patients. And there were four types(Oriental medical Treatment, Information Seeking, Dietary Control. Western Medical Treatment) of subjective opinion about Health Seeking Behaviors. In the relationship between types of the causal perceptions and health seeking behaviors, oriental medical treatment and information seeking type were common health seeking behaviors of all six causal perception types. Only difference for internal causal perception types was related to hospital instructions and external causal perception types were related to dietary control. The result of this study can help health care providers, especially nurses to understand the types of causal perceptions and health seeking behaviors of Rheumatoid arthritis patients to gain treatment compliance from patients according to their causal perceptions of the illness, and use it to develop educational nursing intervention to aid health care.

The purpose of this study is to investigate the characteristics of scientific argumentation and its development in the process of mutual discussion activities by elementary school students in the 5th grade. The results of this study can be summarized as below: First, students used diversity argumentation components for solving the given argumentation theme, however, most students used the assertion or the basis of a simple expression of their own thoughts as a high ratio, and components of a one directional explanatory argumentation process rather than components of a mutual communicative argumentation process. Second, an asymmetric group showed a high-use ratio of communicative argumentation components and achieved argumentation activities harmoniously between a symmetric group and an asymmetric group in organization of groups for solving argumentation themes. It was found that students in the transitional period showed the highest rate of participation within the discussion process. Moreover, they also showed the highest rate of development of discussion skills whilst in the process of using scientific problems. In conclusion, this phenomenon is caused by highlighting the mutual action between the teacher and the student rather than placing an emphasis on the mutual action among students during field instructions.

본 연구는 초등학교 수학에 적용 가능한 수학사를 추출하고 이를 효과적으로 활용할 수 있는 수업 모형을 개발하여, 수학사를 활용하는 수업 이 학생들의 수학적 의사소통과 수학적 태도에 어떠한 영향을 미치는지 알아보았다. 이를 위해 실험집단에는 수학사를 활용한 수업을, 비교집단에는 교과서를 활용한 교사 중심적인 수업을 실시하였으며, 연구 중에 수집된 자료는 양적 분석과 질적 분석 방법을 병행하여 분석하였다. 그 결과 첫째, 의사소통 중심의 수학사 기반 수학 수업은 학생들의 의사소통 참여도를 향상시키는 데에 도움을 주었으며, 둘째, 학생들이 수학적 논리를 가지고 자신의 의견을 상대방에게 정당화하게 하였다. 그러나, 수학사를 활용한 수학 수업이 학생들의 수학적 태도에 통계적으로 유의미한 차이를 가져왔다고 볼수는 없으나, 긍정 적 변화의 조짐을 질적으로 관찰할 수 있었다.

Government archives are basic source materials in the historical study. Whereas, researches on the archives of Choson-chongdokbu have been very scant. Those archives contain information about both colonism of Japan and independent movement of Korea are comparatively well preserved at Government Archives and Record Services. Therefore, it is necessary to analyze the characteristic of archives and to evaluate the system of archival management of Choson-chongdokbu. Based on the official gazette and archives of Choson-chongdokbu, this study has revealed the division of archival work, the writing and treatment of official document, compilation and preservation, and the procedure of use and destruction. As a result of the research, the followings have been identified; 1. Archival regulations were prepared by the instructions of Choson­chongdokbu at the early days of its establishment. Inspite of several revisions, its basis was maintained until 1945. 2. Each agency had its own archival department instead of central archives. 3. The archival department of Choson-chongdokbu controlled the archival administration of headquarters and attached agencies. But the secret archives were managed by the secretarial department. 4. The writing and treatment of archives were done by the archival regulation made in 1911. 5. Each agency had set more or less different preservation period. 6. There were three ways of using archives, 1) the in-house reading 2) the loan 3) the transcriptions. The archives passed the preservation period were destroyed in accordance with the related departments.

Under the relevant regulations, it is required to develop a system architecture for the research and development of the information and communication infra system ; however, the national defense architecture development guides and MND-AF, which provide the instructions on the development and utilization of a system architecture, are still limited to the ITA level and merely providing the guidelines for developing the information system centric architecture. Thus, it is evident that we need a suitable architecture development methodology that corresponds to the growing needs for the communication infra system architecture, as well as the general weapon system architecture. Improving a meta-model is the core of improving a architecture framework. It determines a contents of a architecture and it influences a efficiency and a effectiveness of a architecture. The meta-model of the architecture framework must reflect concerns of various stakeholders and provide a traceability among them. Also, it should be easy to develop and use the architecture by securing the feasibility of the logical relationships and eliminating the duplication of the data inside the architecture. It is implemented through the development of the data-centric architecture and achieved through the "Fit-for-purpose" concept.

With the recent trends and the adaptation of further advancement in personal healthcare system leads to develop some application which can work independent and user can operate that application without much interference of physician or any specialist user. To meet these needs, this paper proposes and implements a progressive architecture for the personal healthcare information system. This new architecture will not only play the role of middleware but also provide a analysis tool to process that different sensor data which is collected from different sensors implemented on patient body and environment. After collecting that data, with the help of various developed applications this data can be convert into useful information which will be stored in application server for further use and research. These features can be enabled by simple and effortless interactions of normal users and act autonomously to support their activities. This proposed personal healthcare architecture will also provide analysis report to the doctors and patient or various users for further instructions. The analysis report consists of healthcare data analysis results and history of patients. We are considering healthcare data like ECG, which is an important aspect for basic healthcare need.
