In Korea, the independent publication market has grown since it came into existence in the 1990s. In 2008, the country's first independent bookstores selling independent publications opened. As of late 2019, there were a total of 466 independent bookstores in Korea and the number of independent bookstores rapidly increased for the last decade. However, the closing rate of independent bookstores is rapidly increasing. This trend is also shown in independent bookstores in Gwangju. Recently, the closing rate of independent bookstores in Gwangju is more than twice as high as the national average. Against this backdrop, this study intended to identify the current conditions of independent bookstores in the city, analyze the problems facing them, and find solutions. Independent bookstores in Gwangju currently make various efforts such as book curation, management of various supplementary programs, and book markets. However, the bookstores have problems including the curation and programs focused on specific areas, focus on limited generations, dependence on publications from the Seoul metropolitan area. To address these problems, this study proposed solutions such as diversifying publications through planning and developing of local contents, strengthening the taste-based salon nature, organizing networks of independent bookstores, and systematically incubating independent bookstores. At the system level, this study also suggested a need for local bookstore certification system, a complete execution of a fixed book price system, and a fair provision rate.

The purpose of this study is to present the factors needed to introduce knowledge management systems to university libraries in Korea, to suggest various methods needed to offer much more improved services of a library than now by investigating the current situations about introducing such factors in national and pubic university libraries in Korea. Almost all of the 33 university libraries selected the subject of investigation have offered the on-line reference service, e-mail pushing service, and full text constructions out of the 11 knowledge management system elements presented in this study, but the other services else have been offered by less than half the number of the libraries. The findings suggest to greatly improve the current services of libraries such as information education and selective dissemination of information, and immediately to introduce new systems including e-book and wireless service systems in order to the university competitiveness. The study implies that each library has already introduced the knowledge management systems, in proportion to a budget of the library, ifs librarian number, and a degree restructuring organization, and that an introduction of knowledge management systems such as policy and culture of organization, its librarian number, and its related security of budget takes the most important role in improving services of a library.

The purpose of this study is (1) to design and test a database which can be automatically classified, and (2) to generate automatic classification number by processing the keywords in titles using the code combination method of Colon Classification(CC) as well as an automatic recognition of subjects in order to develop an automatic classification system (Auto BC System) based on CC which can be applied to any research library. To conduct this study, 1,510 words in the fields of agricultrue and medicine were selected, analized in terms of [P], [M], [E], [S], [T] employed in CC, and included in a database for classification. For the above-mentioned subject fields, the principle of an automatic classification was specified in order to generate automatic classification codes as well as to perform an automatic subject recognition of the titles included. Whenever necessary, editing, deleting, appending and reindexing of a database can be made in this automatic classification system. Appendix 1 shows the result of the automatic classification of books in the fields of agriculture and medicine. The results of the study are summarized below. 1. The classification number for the title of a book can be automatically generated by using the facet principles of Colon Classification. 2. The automatic subject recognition of a book is achieved by designing a database making use of a globe-principle, and by specifying the subject field for each word. 3. The automatic subject-recognition of input data is achieved by measuring the number of searched words by each subject field. 4. The combination of classification numbers is achieved by flowcharting of classification formular of each subject field. 5. The efficient control of classification numbers is achieved by designing control codes on the database for classification. 6. The automatic classification by means of Auto BC has been proved to be successful in the research library concentrating on a Single field. The general library may have some problem in employing this system. The automatic classification through Auto BC has the following advantages: 1. Speed of the classification process can be improve. 2. The revision or updating of classification schemes can be facilitated. 3. Multiple concepts can be expressed in a single classification code. 4. The consistency of classification can be achieved with the classification formular rather than the classifier's subjective judgement. 5. A user's retrieving process can be made after combining the classification numbers through keywords relating to the material to be searched. 6. The materials can be classified by a librarian without subject backgrounds. 7. The large body of materials can be quickly classified by means of a machine processing. 8. This automatic classification is expected to make a good contribution to design of the total system for library operations. 9. The information flow among libraries can be promoted owing to the use of the same program for the automatic classification.

The damage from voice phishing reaches one trillion won in the past 5 years following report of Business Korea on August 28, 2018. Voice phishing and mobile phone scams are recognized as a top concern not only in Korea but also in over the world in recent years. In this paper, we propose an efficient system to identify the caller and alert or prevent of dangerous to users. Our system includes a mobile application and web server using client and server architecture. The main purpose of this system is to automatically display the information of unidentified callers when a user receives a call or message. A mobile application installs on a mobile phone to automatically get the caller phone number and send it to the server through web services to verify. The web server applies a machine learning to a global phone book with Blacklist and Whitelist to verify the phone number getting from the mobile application and returns the result.

The glucose nonfermenting gram-negative bacilli encountered about 10% of all gram-negative bacilli isolated from clinical material. Therefore, a rapid and correct identification of glucose nonfermenting gram-negative bacilli is impostent for a better management of infectious disease. There are many conventional systems for the Identification of glucose nonfermenting gram-negative bacilli but most of them have problems and difficulties. Commercial Kit Systems exist and they are too expensive for dally use 10 Korea because of high cost. Based on 12 selected tests we propose a new code system, MCRCODE-N for rapid and 10-expensive identification of glucose nonfermenting gram-negative bacilli. The selective 12 tests are oxidase, glucose oxidation motility, urease, DNase arginine dehydrolase, nitrate reduction, gelatin Liquefaction, esculin hydrolysis, mannitol oxidation, maltose oxidation, Lactose oxidation. The 12 tests are divided 4 group and then each group has 3 tests. The result of each group is expressed by the number as below. The positive test is given by specific number (1st test = 1, 2nd test = 2, 3rd test = 4), while any negative result is 0. Each 3 numbers of one group are added and make number of 1 digit. Four digit number is refered to the code book of MCRCODE-N system or MCRCODE system using computer (Apple-II model) created by authors. This MCRCODE-N system is suitable ones for our use 10 Korea. We propose the MCRCODEN-N system for clinical use.

This is a survey of the circulation system for students in college & university libraries in Korea. The survey used a questionnaire with 14 questions on 6 items concerning the various aspects of the circulation system in 82 libraries responded among 85 college & university libraries as of 1981. The survey results discovered many problems needing improvement. The following list describes the measures needed to better the problems found in the survey results of 82 libraries. 1. 67.1% of the libraries shows the restricted volumes loaning less than 2 volumes, and 81.7% of the libraries shows the loan periods less than a week, but it is desirable to extend them, when comparing with the size of holdings and the higher educational system at present. 2. It is desirable that the number of a staff in charge of circulation works places one person per average 75-85 books borrowed a day, when calculating an adequate number of the staff on the basis of the correlation between books borrowed a day and number of the staff. 3. 59.8% of the libraries does not have reserved book system, but it is desirable to take it for increasing reliability about the circulation services. 4. More than half of the libraries takes a method of a public announcement on a notice-board for claims of overdue books, but it is desirable to send a claim notice to the individual in viewpoint of keeping their privacies. 5. More than half of the libraries to take the open access system uses a call slip, but it is desirable not to use it in viewpoint of simplicity and economical efficiency of the charging system, because of demanding the unnecessary records. 6. Most of libraries shows many problems of the charging system, especially in factors of the records and filing system, but it is desirable to improve it on the basis of 4 basic factors of the charging system, that is, simplicity, economical efficiency, promptitude and accuracy.

In this paper, we present a Korean syntactic analysis system which can generate all possible syntactic trees in a given sentence. Therefore, the number of syntactic trees by this syntactic analysis system can be increased exponentially. To solve this problem, we suggest a segmentation method and maximum connected unit in a segmentation. Maximum connected unit is a combined unit which contains all morphemes in a segmentation. According to the input sentence, it is possible one or more maximum connected unit in a segmentation. We extract 516 sentences to experiment randomly from the text book of Korean middle school. We could reduce about 28% of the number of syntactic trees.

The main purpose of this study is to explore the effects of the teaching and learning strategy for systems thinking education in elementary students. For this, we developed the teaching and learning material for the systems thinking education based on the book, namely "The tip of the iceberg," and applied to the control group(N=97) of the all students(N=201). The results were as follows. Firstly, the products of the control groups showed more cycle loops than non-control groups. Secondly, the prominent difference of the number of cycle loops was displayed by the 5th graders between control and non-control groups. Thirdly, in this study, applying the teaching and learning strategy for systems thinking education didn't increase the students' thinking ability in terms of quantity. Consequently, this study showed that improving systems thinking ability of higher elementary students is possible through the teleological education.

The purpose of this study is to longitudinally analyze impact factors on library use. One of library use indicators, the number of circulated books was statistically analyzed with latent growth model and growth mixture model. Library data from 2014 to 2019 were collected from the National Library Statistics System, and 846 public libraries were analyzed. As results, the number of circulated books were decreased, but it was tempered. Next, with controlling the factor affecting the dependent variable, the size of collection and the number of participants in reading programs provided by public libraries were statistically significant. Lastly, 5 classes were identified by applying the growth mixture model, and the number of librarians was significantly associated with trajectory class membership.

In the most of speaker recognition system, speaker's characteristics is extracted from acoustic parameter by speech analysis and we make speaker's reference pattern. Parameters used in speaker recognition system are desirable expressing speaker's characteristics fully and being a few difference whenever it is spoken. Therefore we su99est following to solve this problem. This paper is proposed to use strong spectrum characteristic in non-noise circumstance and prosodic information in noise circumstance. In a stage of making code book, we make the number of data we need to combine spectrum characteristic and Prosodic information. We decide acceptance or rejection comparing test pattern and each model distance. As a result, we obtained more improved recognition rate than we use spectrum and prosodic information especially we obtained stational recognition rate in noise circumstance.
