  • One of the most difficult problems in user requirement engineering is the communication gap that exists between different end-users, stakeholders, and software engineers. Since scenarios allow different stakeholders to describe and review the problem in their own language instead of some abstract model, they are also a solution to the problem. We propose a progressive, iterative and interleaved process of using scenario at different requirement engineering stages including elicitation, analysis and validation. This process model has been applied to our TRES System. In our proposed system, we combine prototype, scenarios and use cases in a single and comprehensive framework to avoid most of the shortcomings in other tools. Our system is an XML-based system for scenario-driven requirement engineering. Within the TRES system, scenarios are stories capture information about users and their tasks, including the context of use. In our TRES system, scenarios are stored in XML-based database and described using XML notation.

  • This paper examines 'Religion Class' in the scheme of the DDC. The major findings of the study are summerized as follows. 1. The first edition of DDC was published in 1876 in order to classify Amherst College Library collections. In spite of the continuous study and revision of the experts, the frameworks of the DDC systems are still kept unchanged. Only their subdivisions, reflecting those developments in the academic world, are developed and detailed more sophisticatedly. 2. The division of 200 does not function as generalities for all class of religion. Therefore, it is necessary to amend the division of 200 to serve generalities for all the religions of the world. 3. Standard subdivision for the christian religion and for the non-christian religion is different. So, the mnemonic nature has become weakened due to the dual standard subdivisions and the classification number becomes much longer and complicated. Therefore, one standard subdivision for all religions of the world is required. 4. Religion science was organized in late 19 C and developed continuously, but the DDC does not accomodate the religion science as a science. Accodingly, the DDC should be revised recognize religion science as a science not the christian science. 5. The deployment of classification scheme in Dewey's 200 is severely biased. That is to say, 9 division were assigned for christian religion, whereas only 1 division was assigned for non-christian religion. Therefore, an adjustment should be made to allocate subdivisions equally to all religions of the world. 6. General classification order of religion is prehistoric, primitive, ancient, modem and world religion in religion science. But, DDC does not accept this general classification order of religion, sticking to the biased expansion towards christianity. Therefore, DDC must adopt the general classification order of religion in the religion science. 7. Lastly, because of the limitation of decimal notation in DC, DDC does not accomodate new subject equally and classification number becomes longer. Therefore, centesimal expansion is proposed in order to make the classification number short, to enlarge its capacity of inclusion of new subject and to maintain consistency in the scheme.

  • This study focuses on a review of Hangeul orthography guidelines in Korean language regulations. It is indispensable to revise the guidelines thoroughly because it has been more than 80 years since a unified plan of Korean orthography was established in 1933, which the current orthography is based on. Also, it has been approximately 30 years since 1989, when the current guidelines were issued and promulgated. The viewpoint towards this review reflects the requirements by education fields of Korean as a foreign language and modern Korean users. Hangeul orthography consists of six clauses, along with an appendix regarding punctuation marks: 1) general rules, 2) consonants and vowels, 3) related to sounds, 4) about forms, 5) spacing between words, and 6) miscellaneous. This paper examined individual clauses and specific usages of the clauses, in terms of Korean as a foreign language. Based on the review, this paper suggests the following tasks in order to establish a draft of Hangeul orthography for foreigners. A. Among the individual clauses, some clauses that embody vocabulary education aspects should be addressed in a Korean dictionary, and deleted in Hangeul orthography guidelines. B. The clauses of Hangeul orthography guidelines should be edited for revision and substitution where necessary. C. The usage of individual clauses should be replaced with more appropriate examples aligned with everyday conversation. D. In order to establish 'Hangeul orthography for foreigners', linguists should continuously review several chapters and the appendix of Hangeul orthography, such as components about forms, spacing between words, miscellaneous, and punctuation marks. The purpose of this review is to pursue the simplicity of Hangeul orthography guidelines and the practicality in terms of reflecting more realistic examples. This review contributes to facilitate Korean language usage not only for non-native learners, but also native users.

  • In Kang(2017), Jinho Kang persuasively criticized the attempt of Peter Hanks using his concept of cancelled predication to solve the Frege-Geach problem. According to Kang, Hanks had successfully shown the incoherence of Scott Soames's concept of neutral predication, but if it is true, then Hanks's concept of cancelled predication also falls into the same incoherence. I agree with Kang that Hanks faces the same incoherence, and I think that Hank's answers are unconvincing. As I see, however, it is possible for Hanks to overcome Kang's criticism. In this paper, I will reply to Kang's criticism by using conceptual resources in Hanks's own theory. In particular, the idea is that the final predication is compositionally explained by the type it belongs to without having truth-values because cancelled predication itself gives rise to target-shifting toward the type. By doing so, Hanks can successfully solve the Frege-Geach problem even though he let some remarks about cancelled predication unclear and confusing. In addition, it will be revealed that his notation is misleading as well.

  • The number of traffic accidents is about 230,000, and due to non-recurring congestion and high driving speed, the number of deaths per traffic accident on freeways is more than twice compared to other roads. Currently, traffic information is provided based on nodes and links using the centerline of the road, but it does not provide detailed speed information. Recently, installing sensors for vehicles to monitor obstacles and measure location is becoming common not only for autonomous vehicles but also for ordinary vehicles as well. The analysis using large-capacity location-based data from such sensors enables real time service according to processing speed. This study presents an mapping method for individual vehicle data analysis based on space. The processing speed of large-capacity data was increased by using method which applied a quaternary notation basis partition method that splits into two directions of longitude and latitude respectively. As the space partition was processed, the average speed was similar, but the speed standard deviation gradually decreased, and decrease range became smaller after 9th partition.

  • In this study, we investigated how multiplication by 2-digit numbers had been taught in elementary mathematics textbooks of Korea, Japan, Singapore, and USA. As a result of analysis, we found as follows. Korean textbooks do not teach the multiplication by 10 and the multiplication by power of 10, but Japanese, Singapore, and US textbooks explicitly teach related content. In the '×tens' teaching, Japanese and American textbooks teach formally the law of association of multiplication applied in the process of calculating the partial product of multiplication. The standard multiplication algorithm generally followed a standard method of recording partial product result according to the law of distribution, but the differences were confirmed in the multiplication model, the teaching method of the law of distribution, and the notation of the last digit '0'. Based upon these results, we suggested some proposals for improving the multiplication teaching.

  • Based on the analysis of the appellation from a historical perspective and the diversity of the notation Dokdo island, this study was conducted to analyze the characteristics of cataloging records related to Dokdo in 54 national libraries of the each country. The results are as follows. To begin with, while most of the Dokdo-related records are concentrated in some specific national libraries such as the United States, Australia, and the United Kingdom, there are five libraries that do not have one. Second, the title keyword of Dokdo-related records was 76.1% for 'Dokdo', 17.6% for 'Takeshima', 0.4% for 'Liancourt Rock', and 5.9% for these terms shown together in the national libraries of each country. Third, the subject heading of Dokdo-related records was 54.9% for 'Tok Island (Korea)' or 'Dokdo', 11.2% for 'Takeshima (Japan)' or 'Takeshima', less than 1% for 'Liancourt Rock' and 'Dokdo/Takeshima' each, and 33% for general subject heading or blank.

  • This study attempted to improve the quality of hairstyling-related studies and provide basic data for future studies on hairstyling terms through analysis of cosmetology-related loan words used in hairstyling theses among recent cosmetology papers. For data collection to derive valid conclusions, the signatures of a total of 1,980 academic papers collected after typing in the keyword 'Hair' at the Research Information Sharing Service (http://www.riss.kr) were analyzed. The results show that researchers in hairstyling seem not to pay close attention to the correct use of foreign loan words. Therefore, the study results would be very helpful to the development of future cosmetology studies. The correct notation and use of foreign loanwords should be further encouraged.

  • The importance of color is increasing in modern life and we call such present age that is 'color age'. These day that all areas of life are being getting fashionize, ordinary people as well as design specialist are required of culture and knowledge about color. Color design education is important curriculum at liberal arts course and in special design trainning course. Color expresses by hue, value and chroma in Munsell color system. But design spot is using mainly hue and tone color system. Therefore it is very important that educate tone concept in color design education. When think influence that increase of color, we must develop hue and tone color system in suitable for color design education. This research designed usable 'Hue and Tone 313 Colot System' for efficeint sensual color education. Also I designed 313 color papers with attached the Munsell notation which could reappear the spare color paper when needed. The 10 hues classification of this system are Red, Yellow Red, Yellow, Green Yellow, Green, Blue Green, Blue, Purple Blue, Purple, Red Purple. The 19 tones classification of this system are vivid, light, standard, deep, pale, soft, dull, dark, very pale, light grayish, medium grayish, dark grayish, very dark, off White, off Pale, off Light Gray, off Medium Gray, off Dark Gray, off Black. The special colors of this system are gold, silver and copper.

  • In this paper, we propose a new access control security architecture for supporting flexibility in Secure Operating Systems. By adding virtual access control system layer to the proposed security architecture, various access control models such as MAC, DAC, and RBAC can be applied to Secure Operating Systems easily. The proposed security architecture is designed to overcome the problem of Linux system's base access control system. A policy manager can compose various security models flexibly and apply them to Operating Systems dynamically. Also, the proposed architecture is composed of 3 modules such as access control enforcement, access control decision, and security control. And access control models are abstracted to hierarchy structure by virtual access control system. And, we present the notation of policy conflict and its resolution method by applying various access control model.
