As the application domains of rule-based systems become larger and more complicated, the integration of rule-based systems within the database systems has become the topic of many research works. This paper suggests a simulation modeling using expert system and database. The integration methods employed in this research are as follows. First, we defined new states and state transition functions to interrelate simulation model and expert system. Second, we designed and implemented FCL(Fact Class Library) as a interface of expert system and database. FCL has facilities of filtering data from database, and assigning a meaning to the filtered data. Also, FCL detects the violation of the integrity rules in database, as the result of inference is reflected. Some implementation problems are pointed out and the methods to solve these problems are discussed in this paper, We developed a simulation model of the grating production line and executed it to validate the functions of the proposed method.

지식분류는 개념을 설정하고 정의를 내린 후 학문명칭을 부여한다. 문헌분류법은 지식기반 원칙이므로 학문명칭을 실용성 우선으로 하여 주류명을 설정하는 단궤로부터 시작된다 어떤 분류법도 지식의 최초의 구분은 주류(main classes)를 창출하는 일이다. 주류는 일반적으로 전통적 학문분류와 등가이다. 그러나 주류의 설정은 지식구분과 동일한 순차는 존재할 수 없다. 그래서 주류를 구성하는 일은 다양할 수밖에 없다. 어느 분류법이든 두 가지 관념이 기본이 되는데 군집화와 순차화이다. 그렇다면 군집화는 주류명을 부여하는 단계라면, 순차화는 주류순을 결정하는 단계라고 할 수 있다. 문헌분류법에서 각각의 주류를 열거하고 있으나, 이에 대한 명확한 기준이나 철학이나 이론적 근거를 규명할 수는 없다. 그렇지만 이러한 주류설정의 원칙이나 이론 등은 전혀 연구된바가 없다. 따라서 본 연구에서는 분류표의 총체적인 구조의 근거가 되는 주류의 설정원칙과 그 논리를 연구하고자 함이 목적이다.

이 논문은 KDC 제5판에서 개정된 철학류의 항목들에 대해 분석한 것이다. 기존의 KDC 제1판부터 제4판까지 철학분류에서는 어떤 내용들이 전개되고 개정되고 변화되어왔는지 항목별로 비교한 결과 일부 용어의 변경이나 분류기호의 이동, 항목의 신설 및 삭제가 있긴 했지만 KDC 제1판의 기본틀에서 크게 벗어나지 못하였음을 알 수 있었다. KDC 제5판에서는 형이상학과 인식론을 수정 전개하여 동위항목으로 배정하였고, 심리학 중에서는 자료가 늘어나는 양성심리, 발달심리, 상법 운명판단, 응용심리학을 확장 전개하였으며, 윤리학 도덕철학부분을 수정 전개하는데 역점을 두어 살펴본 것이다.

The Result of the study can be summarized as follows : (1) Korean culture and public library look extremely wasted equally. Judging from this fact, I believe that it is impossible for public library can contribute to development of Korean culture. (2) But, public library can contribute to development of culture in the cultural environment that mental desire is prior to physical wants. This cultural environment can be built up with reading of good books. Therefore, if class to reading education and diverse reading education programs can be activated in a large portion of the nationwide public libraries and the majority of a local resident are capable of improving their creativity power, thinking power and imaginative faculty, public library can contribute to produce such cultural circumstances. (3) Quality, culture, a human and mind receive mu6 respect in Korean Society as advanced civil, democratic and industrial society in the future. The Society will be influenced by reason and rational culture will be suitable to this society. Creativity power, thinking-power, imaginative faculty, intelligence and power of information management are demanded to the greatest degree for the development of idea and new technology in the society under the control of rational culture. So, lifelong education with library use is the most fruitful and inexpensive way for the improvement of these powers.

The purpose of this study is to analyze the area table of twenty editions of the DDC in order to identify what major changes have been made chronologically. The summaries about which were discussed according to the edition order about the change processes of the most extensive area table of the DDC auxiliary table are as follows. 1. It is from the 17th edition that area table appeared as a special auxiliary table in DDC for the first time and the method of classifying areas like from 930 to 999 which is regional history in history class was taken before the introduction of independent area table. 2. The entry numbers in which the area table was applied increased continuously until the 18th edition but the applied entry number was rather decreased in the 20th edition especially the number was mainly decreased in history class, this is the result of the fact that the entry was classified by area table without enumerating each regional history in history class except for the basic area since the 17th edition but recently at least the area of over national unit according to the necessity of enumerating the entry in regional history within history class. 3. The relocation or revision of area table was made according to the literary warrant of the relevant area by period political and administrative conditions and the request of related organization or classifiers of the area rather than by the topographical features therefore the revision was made chiefly about the highly interested Europe Northern America especially the United States. 4. The entry numbers which were expanded according to area indicate that gradual improvement for the international feature as the revision of edition is repeated is made but because of the expansion of Northern America, especially the United States, regional disproportion is represented by the occupation of 56% in the entire entry numbers of the United States in case of the 20th edition. Lastly, the reasonable reform plans of area table will have to be groped on the basis of the results of analysis above and the consideration about the problems in the development of area table of DDC and the other main classification systems.

HCCL 이란 Heterogeneous Container Class Library의 약자로써, 이종의 데이터 유형을 하나의 레코드로 저장이 가능하도록 하고, 이의 리스트를 만들어 정보의 저장이 가능하도록 하는 라이브러리이다. HCCL을 사용할 경우, 데이터 유형이 다르더라도 암/복호화를 문자열을 기반으로 용이하게 할 수 있다. 최근 스마트폰에 내재되어 있는 다양한 센서들을 활용하여 사용자에게 편리한 서비스를 제공해 주고 있다. 하지만, 센서 정보를 API에 전달해 주는 과정에서 개인 정보의 침해가 발생할 수 있으며, 이에 대해 사용자들의 대비가 필요한 것도 사실이다. 본 연구에서는 센서의 정보를 HCCL을 기반으로 관리하면서 SEED 암호 알고리즘을 활용한 기존의 보안성을 강화하는 데이터 모델을 개발하였다. 안드로이드 환경이 센서에 대한 권한 관리 기능을 제공하지 않는 문제가 있음으로, 본 연구에서는 사용자의 판단을 기반으로 한 선택을 통해 센서 정보의 암호화 여부가 결정되도록 하여 안전한 데이터의 생성 및 저장을 사용자가 판단하도록 하였다. 또한, 개발된 라이브러리의 성능을 평가하여 본 연구의 효과성을 검증하였다.

Dewey Decimal Classification (DDC) was first published in 1876. Since its first edition it has been revised, on an average, 6 years, and now it has become the widely used library classification system of which the scheme was translated in various languages. The purpose of this study is to find out the chief causes for the development of the DDC. The results of the study can be summarized as follows: 1. It allows materials to be shelved in a relative location as the collection expands. before the DDC was introduced, libraries used a fixed location for materials in which each item was assigned to a certain location set aside for a subject. 2. It is a practical system. The fact that it has survived many storms in the past hundred years and is still the most widely used classification scheme in the world today attests to its practical value. 3. The pure notation of arabic numerals is universally recognizable. People from any cultural or language background can adapt to the system easily. 4. The use of the decimal system enable infinite expansion and sub-division. And it has adaptability for use in libraries of various size and kinds because of its hierarchically expressive notation which permits varying degrees of inclusiveness and exclusiveness within its decimal structure. 5. The notation is simple and easily understood. The self-evident numerical sequence facilitates filing and shelving. And the mnemonic nature of the notation helps the readers to memorize and recognize the class numbers. 6. The relative index brings together different aspects of the same subject scattered in different disciplines. 7. We can avail of DDC numbers for specific titles easily because of its use by many central bibliographic services. 8. It is being continuously revised by a permanent office established in the library of congress in 1933. This office has been responsible for editing all editions of the DDC since the 16th (1958). And the periodic revision at regular intervals ensures the currentness of the scheme. 9. It has adaptability both for conventional (manual) shelf or classed catalogue analysis and also, through its meaningful nation, for retrieval through mechanization and computerized systems.

Nakseonjae in Changdeokgung Palace was established at The King Hunjong's 13rd year (1847), the mid-19th century. It was constructed for own rests of King Hunjong and the residence of Kyungbin (king's concubines), and is showing features of upper-class houses from several points such as rustic architectural types by getting out of authoritative aspects as king's shelter space within the palace, block and floor distribution that separated spaces for men and women, simplicity in structures and styles, and non-colorful painting etc. This study aims at tracing on which architectural types did the upper-class houses within Hanyang (modern Seoul) at late Joseon Dynasty have and what was characteristics of Nakseonjae. The resemblance between Nakseonjae and the upper-class houses was very little differences from scale aspects, and floor plan shapes of Anchae (women's quarters) and Sarangchae (men's quarters) were followed basic common styles. Also, resemblance could be confirmed in the structural styles too. Characteristics of Nakseonjae are showing apparent differences from clearance compositions such as hall configuration etc. Nakseonjae was king's dwelling place, and spaces for house's collateral functions such as kitchen, stable, and warehouse etc together with shrine were unnecessary, and such places were substituted into servants' quarters for assisting the Royal family. In detailed structural styles, column's size was larger 3cm or more than the upper-class houses, and its height was higher to the degree of 30~60cm. Besides, formality as king's shelter space was raised more in decorating aspects, and Nakseonjae was implemented by getting architectural influences from Qing Dynasty of China. This study induced features of Hanyang's upper-class houses at the 19th century by supplementing distribution and space configurations at existing cases of Seoul and Gyeonggi area together with house diagrams having been collected by Gaokdohyung (site and floor plan) of Jangseogak Library, and confirmed resemblances and differences with Nakseonjae, that is, features of Nakseonjae. Through the result, this study judges a fact that architecture of Nakseonjae seemed to be affected from conveniences of upper-class houses within Hanseong, and also architectural styles and distribution types of Nakseonje would give influences to the upper-class houses.

The ability of any organization to innovate itself in a rapid change of environment means the existence of the organization. Innovative activity is achieved in different ways according to the objectives of organization. the characteristics of external environmental factors. and various attributes in organization. In the present study. all the existing approaches to the innovative nature of organization were synthetically compared to each other and evaluated: then. for a more rational approach. a research model was built and suggested by establishing the inclusive variables of the innovative nature of library organization and categorizing the types of such nature. Additionally. an empirical. analytical study on such a model was done. That is. paying regard to the fact that innovation has basically a close relation with the circumstantial factors of organization. synthetic, circumstantial relations were clarified. considering the external environmental factors and internal characteristics of organization. In the study. the innovation of library organization was seen in two parts i.e .. the feasible degree of technical innovation and the feasible degree of administrative innovation. Regarding the types of innovative implementation. according to the feasible degree of innovation, four types such as a stationary type. technic-oriented type, organization-oriented type. and technical-socio systematic type were classified. There were nine independent variables-i.e., the scale of organization. available resources of the organization, formalization, differentiation, specialization. decentralization, recognizant degree of the technical attribute. degree of response to the change of technical environment, and professional activities. There were three subordinate variables - i.e., technical innovation, administrative innovation. and the performance of organization. Through establishment of such variables, the factors which might influence the innovation of library organization were understood, and with the types of the innovative implementation of library organization being classified according to the feasible degree of innovation. the characteristics of library organization were reviewed in the light of each type. Also. the performance of library organization according to the types of the innovative implementation of library organization was analyzed. and the relations between the types of innovative implementation according to circumstantial variables and the performance of library organization were clarified. In order to clarify the adequacy of the research model in the methodology of empirical study, data were collected from 72 university libraries and 38 special libraries. and for a hypothetical test of the research model. an analysis of correlations, a stepwise regression analysis. and One Way ANOVA were utilized. The following are the major results or findings from the study 1) It appeared there is a trend that the bigger the scale of organization and available resources are, the more active the professional activity of the managerial class is, and the higher the recognizant degree of technical environment (recognizant degree of technical attributes and the degree of response t9 the change of technical environment) is, the higher the feasible degree of innovation becomes. 2) It appeared that among the variables influencing the feasible degree of technical innovation, the order from the variable influencing most was first, the recognizant degree of technical innovation: second, the available resources of organization: and third, professional activity. Regarding the variables influencing the feasible degree of administrative innovation from the most influential variable, it appeared they were the available resources of organization, the differentiation of organization. and the degree of response to the change of technical environment. 3) It appeared that the higher the educational level of the managerial class is, the more active the professional activity becomes. It seemed there is a trend that the group of library managers whose experience as a librarian was at the middle level(three years to six years of experience) was more active in research activity than the group of library managers whose experience as a librarian was at a higher level(more than ten years). Also, it appeared there is a trend that the lower the age of library managers is, the higher the recognizant degree of technical attributes becomes. and the group of library managers whose experience as a librarian was at the middle level (three years to six years of experience) recognized more affirmatively the technical aspect than the group of library managers whose experience as a librarian was at a higher level(more than 10 years). Also, it appeared that, when the activity of the professional association and research activity are active, the recognizant degree of technology becomes higher, and as a result. it influences the innovative nature of organization(the feasible degree of technical innovation and the feasible degree of administrative innovation). 4) As a result of the comparison and analysis of the characteristics of library organization according to the types of innovative implementation of library organization. it was indicated there is a trend that the larger the available resources of library organization, the higher the organic nature of organization such as differentiation. decentralization, etc., and the higher the level of the operation of system development, the more the type of the innovative implementation of library organization becomes the technical-socio systematic type which is higher both in the practical degrees of technical innovation and administrative innovation. 5) As a result of the comparison and analysis of the relations between the types of innovative implementation and the performance of organization, it appeared that the order from the highest performance of organization is the technical-socio systematic type, then the technic-oriented type, the organization­oriented type, and finally the stationary type which is lowest in such performance. That is, it demonstrated that, since the performance of library organization is highest in the library of the technical-socio systematic type while it is lowest in the library whose practical degrees in both technical innovation and administrative innovation are low, the performance of library organization differs significantly according to the types of innovative implementation of library organization. The present study has extracted the factors influencing innovation, classified systematically the types of innovative implementation, and inferred the synthetical, circumstantial correlations between the types and the performance of organization, and empirically inspected those factors. However, due to the present study's restrictive matters and the limit of the research design, results from the study should be more prudently interpreted. Also, the present study, as an investigative study of the types of innovative implementation, with few preceding studies, requires more complete hypothetical inference based on the results of the present study. In other words, if more systematical studies are given to understanding the relations, it will devote the suggestion and demonstration of a more useful theory.
