자바는 객체 지향언어로 네트워크 기반의 환경에서 응용프로그램을 효율적으로 개발을 위해 설계되었으며 특정 하드웨어나 운영체제에 영향을 받지 않고 동작 할 수 있는 높은 이식성을 가지고 있다. 하지만 자바 언어로 응용프로그램을 개발하면 다른 언어로 작성하는 것 보다 일반적으로 실행이 느리다는 단점이 발생하게 된다. 이를 극복하기 위해 자바 언어에 대한 최적화가 필요하다. 일반적으로 많이 쓰는 최적화 방법으로는 JIT와 같이 실행시간에 필요에 따라 컴파일하여 실행하는 방법과 바이트코드를 수행하고자 하는 특정 프로세서에 적합한 네이티브 코드를 생성하는 방법을 사용하고 있다. 하지만 이러한 방법들은 고유의 최적화 기법과 구현된 프로그램을 이용해서만이 최적화가 가능했고 또한 코드의 추출부터 최적화를 위한 모든 부분까지 구현해야하는 문제점이 있다. 또한 자바 바이트코드는 스택기반의 코드로써 명령어가 많고 표현이 명백하지 않다는 문제점을 가지고 있다. 따라서 분석과 변환이 어렵기 때문에 자바 바이트코드를 스택 기반이 아닌 분석과 최적화가 용이한 3-주소 형태로 변환하여 최적화 기법을 적용해야 한다 본 논문에서는 자바 바이트코드와 3-주소 형태의 중간 코드인 CTOC-B에 대해서 설계한다.

From the perspective of science gifted education, the successful intelligence theory is a means to understand how the gifted education curriculum reflects the characteristics of science gifted students. The purpose of this study is to investigate if the successful intelligence is fully reflected in the teaching materials of two gifted education centers (GECDOE: Gifted Education Center affiliated with District Office of Education, GSEIU: Gifted Science Education Institute attached to University). For this study, we selectively used 143 (GECDOE) and 134 questions (GSEIU) from the teaching materials of two gifted education centers. Those questions is analyzed through the semantic network analysis method. The results are as follow. First, the teaching materials of two gifted education centers are not evenly reflected in the successful intelligence, such as analytical ability, creative ability, and practical ability. Second, the teaching materials of two gifted education centers intensively demands analytical ability for students such as 'identify problem', 'represent and organize information', and 'additional prompts for analytical thinking'. Third, the teaching materials of two gifted education centers are presented to students without linking each frame of successful intelligence to one another. As the gifted students are quick to learn and show a preference for more complex thinking, it is necessary to develop teaching materials to experience the various abilities and promote integrated thinking according to the level of the gifted students. In this respect, this study is expected to be used as useful information for developing teaching materials to support customized education for gifted students.

Objectives: The purpose of this study is to explore the research trends of elderly oral health through a language network analysis. Methods: A total of 354 published studies with 668 keywords were collected from the Research Information Sharing Service (RISS) between 2000 and 2022. Language network analysis was performed using Textom 6.0, Ucinet 6.774, and NetDraw 2.183. Results: The most frequent keywords were 'elderly', 'oral health', 'quality of life', and 'OHIP-14'. The result of frequency-inverse document frequent keywords showed similar results to the most frequent keywords. The N-gram of keywords shows that 'elderly', 'oral health' (18 times) and 'elderly', 'depression' (7 times). As a results of the analysis of degree centrality and between centrality, 'elderly', 'oral health', and 'quality of life' were found to be high. The CONCOR analysis identified the main clusters of 'quality of life', 'oral health behavior', 'health', and 'oral function disorder'. Conclusions: The results of the current study could be available to know research trends in elderly oral health and it is necessary to improve more comprehensive study in follow-up study.

기술의 발전과 함께 사용자에게 가까이 자리 잡은 소셜 네트워크 서비스는 이미지, 동영상, 텍스트 등 활용 가능한 데이터의 수를 폭발적으로 증가시켰다. 작성자의 감정을 포함하고 있는 텍스트 데이터는 시장 조사, 주가 예측 등 다양한 분야에서 이용할 수 있으며, 이로 인해 긍부정의 이진 분류가 아닌 다중 감정 분석의 필요성 또한 높아지고 있다. 본 논문에서는 딥러닝 기반 감정 분류에 심리학 이론의 기반 감정 모델을 활용한 결합 모델과 단일 모델을 비교한다. 학습을 위해 AI Hub에서 제공하는 데이터와 노래 가사 데이터를 복합적으로 사용하였으며, 결과에서는 대부분의 경우에 결합 모델이 높은 결과를 보였다.

In this study, quantitative and content analysis was conducted on 37,818 news articles that were reported on the subject of 'library' for 29 years from 1990 to 2018 in order to analyze the tendency of media coverage about 'library'. First, the quantitative change in media coverage was analyzed according to the criteria by time, subject and media type. In addition, keyword frequency analysis and semantic network analysis were conducted to analyze the trends of the contents of the press and the frames inherent in the press. The results showed that the media showed a major interest in the library's informational, educational, and cultural functions, and the trend of the subject's interest was generally consistent with that of the library community, except for the issue of librarianship. Lastly, the main attitudes that the media take toward the reporting of library articles were the reporting and advertising functions.

최근에 사용자 행태 분석 개념이 매우 중요한 이슈가 되고 있다. 하지만 SE(Software Engineering)와 HCI(Human-Computer Interaction) 두 분야의 틈으로 HCI 관점의 시스템 모델링을 위한 적절한 모델링 언어나 도구가 부족하다. 그리고 원시 데이터를 분석하여 사용자 행위를 모델링하는 것은 실제로 어려운 작업이다. 이 논문에서는 목적(Goal)지향의 사용자 행위 분석을 통해 객체를 식별하고, 추출한 공통/비공통 행위를 기반으로 시스템을 모델링 하고자 UBA(User Behavior Analysis)방법론을 제안한다. 그리고 유비쿼터스 환경의 홈 네트워크 인터페이스 모델을 적용 사례로 언급하였다.

이벤트란 객체 상태 변화에 따른 상황 변화를 의미한다. 이벤트를 표현할 때 어떤 요소들을 표현하느냐에 따라 유추할 수 있는 정보 내용이 각각 달라진다. 본 논문은 일반적인 이벤트 표현을 위해 필요한 구성요소들을 제안하고 이 구성요소들을 기반으로 기존에 제안된 이벤트 표현 방법들을 분석 비교한다. 본 논문에서 제안한 이벤트 표현 구성요소들은 표현력 측면에서 이벤트 표현 방법들을 분석하고 비교하는데 타당한 기준이 될 수 있고 향 후 이벤트를 표현하거나 추론하는 방법 혹은 언어를 개발하는데 필수적인 요소가 될 수 있다. 또한 논문에서 제시한 기존 이벤트 표현 방법 분석과 비교는 사용자가 이벤트 표현 방법을 선택하는데 있어 좋은 가이드라인이 될 수 있다.

In this paper, we develop protocol analyzer that can analyze and monitor LAN(Local Area Network)-based TCP/IP protocol using the OOP(object-oriented programming) in Windows98/NT environment. TCP/IP(Transmission Control Protocol/Internet Protocol) protocol analyzer is consist of interface hardware, protocol analysis software and GUI(Graphic User Interface). It is designed for the real-time analysis using the real-time object. In results of Performance test, TCP/IP Protocol analyzer is showed that it can analyze and monitor without frame error in LAN-based. Also, developed protocol analyser operates better than conventional protocol analyzer in performance. It can be used in maintenance fields of communication and network.

The modern society is rapidly changing, and accordingly, the required teacher image is changing as well. Middle school students are immature, when they undergo major changes both physically and mentally, and teachers have a great influence. How students perceive the teacher determines the relationship between teachers and students. Therefore, it is necessary to analyze what kind of teacher image middle school students want. The purpose of this study is to analyze the image of a science teacher who prefers and avoids each class situation perceived by middle school students. To this end, 502 middle school students were divided into five classes: class type, class material presentation method, subject instruction method, subject content explanation method, and class atmosphere, and the image of science teacher who prefers and avoids is described in an open format. Concepts presented by middle school students were analyzed through semantic network analysis (SNA). The conclusions of this study are as follows: first, in order to make middle school students interested in science, an inquiry-centered experiment class should be conducted. Second, the change of class by science teacher can change it into preferred science class. Third, student-centered classes should be conducted according to the level so that students can understand. Finally, science teachers continue to strive through communication between science teachers and students, and students and students, and look forward to changes in science classes through this.

The purpose of this study is to analyze the research trends in domestic related to gifted counseling by utilizing Sementic analysis methods. For papers of gifted education in korea, KCI(Korea Citation Index) rated journals were selected 83 pieces published in journals were collected and the Sementic Network Analysis(SNA) way was utilizing for keyword frequency and Centrality Network Analysis throughout a variety of research articles using krkwic and Ucinet6.0. The results are as follows. first, the analysis appeared that the trends of paper keywords from highest frequency of appearance keyword in papers focused on four keywords: perfectionism, career, counseling, and the science gifted. second, Analysis of annual trends from 2001 to June 2018 showed that the top keywords were as follows: the gifted underachievers, the perfectionism, the gifted students of Science, and the science gifted students. the rising keywords were perfectionism, twice-exceptional students, and gifted parents, and the keywords of gifted students and general students showed a tendency to decrease. Consequently, gifted counseling research should be done from various perspectives.
