  • Although the number of smartphone users is continuously increasing due to the advantage of being able to easily use most of the Internet services, the number of counterfeit applications is rapidly increasing and personal information stored in the smartphone is leaked to the outside. Because Android app was developed with Java language, it is relatively easy to create counterfeit apps if attacker performs the de-compilation process to reverse app by abusing the repackaging vulnerability. Although an obfuscation technique can be applied to prevent this, but most mobile apps are not adopted. Therefore, it is fundamentally impossible to block repackaging attacks on Android mobile apps. In addition, personal information stored in the smartphone is leaked outside because it does not provide a forgery self-verification procedure on installing an app in smartphone. In order to solve this problem, blockchain is used to implement a process of certificated application registration and a fake app identification and detection mechanism is proposed on Hyperledger Fabric framework.

  • The first step of this study is to collect appropriate words from the list of words in the relationship. All vocabularies that are unfamiliar-but capable of guessing the meaning and expressing interpersonal relationships-were collected from three Korean dictionaries. Consequently, a compilation of 2,725 words was created; overlapping words were selected; and 910 words were chosen. Only grammatical forms were found; however, words with similar meanings-or identical meanings-were also found, and a reclassification process was required to reflect this. These procedures were repeated seven times, resulting in a total of 249 words being screened. However, due to the characteristics of this study, the number of words needs to be reduced because the meaning of words is more specific and summarized, and the overall interpersonal aspect is well expressed. Therefore, the process of reclassifying 249 words by their familiarity and appropriateness was subsequently undertaken, and the word with the highest level of familiarity and appropriateness was finally selected.

  • In order to create future-oriented special school facilities with a high-quality educational environment in response to various changes and demands of the times, it is necessary to break away from the existing uniform and formal framework to find appropriate special school space. This study was a basic research to construct an active detailed model of new and creative educational space that reflects the changes of future society and educational direction. In this study, we proposed a criteria based on case studies and expert advice, deviating away from the limitations and problems that existing special schools' educational space had. The direction of plan was presented based on the compilation of expert consultation and analysis of best practice facility survey across the nation. Based on the results of this study, it is intended to maximize the effectiveness of educational policies in the long term by preparing a specific facility model for the establishment of special school planning standards.

  • This study investigated the status and analyzed of stray dogs, stray cats admitted to the Jeju Animal Shelter during the year of 2015 to 2019, and the infection rates of specific diseases for abandoned dogs. In addition, in 2017 to 2019, the collected intake and outcome data were reviewed to analyze shelter capacity in terms of housing capacity (monthly daily average intake, required holding capacity, and adoption-driven capacity), staff capacity (staff hours required for daily care). Out of 24,557 dogs admitted to the shelter, owners of 1,808 dogs (7.4%) visited the shelter and found their lost dogs, while 3,612 dogs (14.7%) were adopted to new families. However, the number of puppies that were euthanized was the highest at 12,266 (49.9%), and 6,876 (28%) died either death from disease or natural causes because they were detained in shelters. The monthly daily average (MDA), which is one of the indicators for efficient population management of Jeju Animal Shelter, was found to be 17.4 for abandoned dogs and 1.7 for abandoned cats. Seasonal variations were observed for MDA, RHC, MDA adoptions, ADC, and RSDC, indicating that various strategies are needed for shelter management. This study was performed to analyze and interpret meaningful statistics for improving the efficiency of animal shelters in Jeju. However, inconsistent collection of animal statistics limited data compilation. Creation of a basic animal statistics matrix with reference to well-designed matrices from recognized professional animal shelters is essential.

  • This paper deals with the problem of appropriately allocating multiple processors arriving at the ready queue to the block in the user space of the main memory is divided into blocks of variable size at compilation time. The existing allocation methods, first fit(FF), best fit(BF), worst fit(WF), and next fit(NF) methods, had the disadvantage of waiting for a specific processor because they failed to allocate all processors arriving at the ready queue. The proposed algorithm in this paper is a simple block packing algorithm that allocates as many processors as possible to the largest block by sorting the size of the partitioned blocks(holes) and the size of the processor in the ready queue in descending order. The application of the proposed algorithm to nine benchmarking experimental data showed the performance of allocating all processors while having minimal internal fragment(IF) for all eight data except one data in which the weiting processor occurs due to partition errors.

A Study on the Origin, Spread, and Universalization of the Name 'Chonggak kimchi': In Connection with the Food Culture Content Point of View ('총각김치' 명칭의 시작과 확산, 그리고 보편화 과정 고찰: 음식문화 콘텐츠 관점을 연계하여)

  • Research on the birth (起源) and names (語源) of foods such as kimchi is important to understand traditional food culture. kimchi, an 'add flavored, fermented, pickled, vegetable food' was initially prepared with the simple purpose of increasing storage capabilities, but later, through a complex process of change, morphological diversification occurred. In addition to the basic name of 'kimchi', each variety has its unique name and history. This study was conducted through qualitative research using various research methods, such as oral records and interviews, as well as investigation of data from literature, including ancient literature, modern cookbooks, newspapers, magazines, papers, and videos. The study sought to investigate the context and the meaning of the name Chonggak kimchi. In addition, it is a compilation of how the name spread through the ages and evolved to its current name. The name Chonggak kimchi did not exist during the Joseon Dynasty and Japanese occupation and first appeared in the records in the late 1950s. Nevertheless, the original name of 'Altarimu kimchi' evolved and finally became a part of the standard Korean language (標準語) in 1988. In the process of the name spreading and becoming popular, the movie "Chonggak kimchi (1964)," starring Shin, S.I., and Eom, A.R. played a significant role. It was also confirmed that this was a meaningful and valuable case of contentization of traditional food culture, regardless of the intention behind the same.

  • This corpus-driven research expounded the compilation of the most frequently occurring academic words in the domain of syntax and compared the extracted wordlist with Academic Word List(AWL) of Coxhead(2000) and General Service List(GSL) of West(1953) to examine their distribution and coverage within the syntax corpus. A specialized 546,074 token corpus, composed of widely used must-read syntax textbooks for English education majors, was loaded into and analyzed with AntWordProfiler 1.4.1. Under the parameter of lexical frequency, the analysis identified 288(50.5%) AWL word forms, appeared 16 times or more, as well as 218(38.2%) AWL items, occurred not exceeding 15 times. The analysis also indicated that the coverage of AWL and GSL accounted for 9.19% and 78.92% respectively and the combination of GSL and AWL amounted to 88.11% of all tokens. Given that AWL can be instrumental in serving broad disciplinary needs, this study highlighted the necessity to compile the domain-specific AWL as a lexical repertoire to promote academic literacy and competence.

  • In order to analyze the similarity of the source code object material, the source code on both sides must be able to be compiled and executed. In particular, in the case of hardware-integrated software, it is necessary to check whether the hardware interface matches. However, currently, the source code is provided in an incomplete state which is not original of source code used in developing steps. The complainant confirms that the executing characteristics are similar to their own in the expression and function of the output, and request an evaluation. When a source code compilation error occurs during the evaluation process, the experts draw a flowchart of the source code and applies the method of tracing the code flow for each function as indirect method. However, this method is indirect and the subjective judgment is applied, so there is concern about the contention of objectivity in the similarity evaluation result. In this paper, the problems of unverified source code similarity analysis and improvement directions are dealt with, through the analysis cases of source code disputes applied to embedded systems.

  • Through literary research, this study aims to study chinese characters in the Chosun Dynasty from the perspective of international exchange. While sorting out the historical materials, it investigates the implementation organ, educational content and main characteristics of Chinese education in the Chosun Dynasty, its influence on the Korean peninsula at that time and Its enlightenment to today's Chinese international education. The results show that the Chinese language education institutions in the Chosun Dynasty mainly played the role of Chinese language education in the Si service academy and the Sheng Wen Academy. The contents of Chinese language education mainly include the development of oral Chinese teaching materials, the publication of rhymes and other reference books, the compilation of dictionaries and the training of Chinese translators. Through the in-depth study of Chinese rhymes, the Korean Peninsula created its own Korean national character in 1443, getting rid of the will of Chinese characters. The invention of Korean language has greatly encouraged the political, economic and cultural development of the Korean peninsula. In addition, the Chinese language education in the Chosun Dynasty provides a good experience for today's Chinese international education in China.
