프로그래밍 언어 실습을 위해 일반적으로 실습 소프트웨어를 여러 대의 PC에 개별적으로 설치하거나, 실습 소프트웨어를 특정 서버에 설치한 후 라이센스를 받아 운영하고 있는 경우에는 접속자의 수를 제한 받게 되는데, 이러한 모든 경우들에는 지정된 장소에서만 실습을 해야 하는 문제점과 실습자 수의 제한 문제점이 있다. 본 논문에서는 실습 소프트웨어 1본을 서버에 설치한 후 인터넷이 가능한 어떠한 장소에서 다수의 학습자가 프로그래밍 실습을 할 수 있도록 웹기반 학습시스템을 개발하였다. 이 웹기반 학습시스템에서 학습자가 인터프리팅 또는 컴파일링, 실행 등을 요청할 때에만 실습 소프트웨어를 점유하기 때문에 접속자 수의 제한 문제를 해결하였다. 뿐만 아니라, 이 웹기반 학습시스템은 실습 효과를 증진시키기 위하여, 예제 프로그램과 그에 대한 동영상 설명, 학습자의 학습 이력, 오류가 발생하였을 때 그에 대한 참고자료 등을 이용할 수 있도록 개발되었다.

Atomic behavior during ion beam sputtering was investigated by using classical molecular dynamics simulation. When Ar ion bombards on Au and Pd(001) surface with various incidence energies and angles, some atoms which gained substantial energy by impacting Ar ion were sputtered out and, simultaneously, others were landed on the surface as if surface atoms were redeposited. It was observed that the redeposited atoms are five times for Au and three times for Pd as many as sputtered atoms irrespective of both incidence energy and angle. From sequential ion bombarding calculations, contrary to the conventional concepts which have described the mechanism of surface pattern formation based only on the erosion theory, the redeposition atoms were turned out to play a significant role in forming the surface patterns.

The actual performance of a building during an earthquake depends on many factors. The prediction of the seismic performance of a new or existing structure is complex, due not only to the large number of factors that need to be considered and the complexity of the seismic response, but also due to the large inherent uncertainties and randomness associated with making these predictions. A central issue of this research is the proper treatment and incorporation of these uncertainties and randomness in the evaluation of structural capacity and response has been adopted in the seismic performance evaluation of steel tall buildings to account for the uncertainties and randomness in seismic demand and capacities in a consistent manner. The basic framework for reliability-based seismic performance evaluation and the key factors for statistical studies were summarized. A total of 36 target structures that represent typical tall steel buildings based on national building code (KBC-2005) were designed for the statistical studies of demand factor s and capacity factors. The incremental dynamic analysis (IDA) approach was examined through the simple steel moment frame building in determination of global drift capacity.

In this paper, we simulated disaster broadcast service using terrestrial UHD additional data. We looked at nine functions(warning alarm, location-based information, multilingual, re-viewing the title of breaking news, evacuation knack video, CCTV, clip video, wake up, automatic channel switching) by referring to ATSC 3.0 standards. Analyzing the advantages and problems of the proposed disaster broadcast. Expert interviews were conducted after a demonstration and explanation of terrestrial UHD disaster broadcast. They said that the problems with the technology were difficulty in using, obstruction of viewing, content creation problems, and problems with advertisers. In addition to the lack of simulation-based research, this research has provided an insight into the technology by showing it in a visible way. This helped shape the advantages and problems of technology.

This study verified the relationship between health cognition, subjective quality of life, and intention to continue exercise among participants in an exercise rehabilitation program. The researcher explained the purpose and questionnaire information in detail through the cooperation of the center, and after consenting, 204 copies were selected, excluding 24 copies judged to be unreliable out of a total of 228 copies. For the survey, the researcher explained the purpose and questionnaire in detail through the cooperation of the center, and after consenting, a total of 204 copies of data were collected. The collected data were subjected to frequency analysis, descriptive statistics, factor analysis and reliability analysis, and correlation analysis and regression analysis were applied to identify the relationship between latent variables. As a result of the analysis, it was found that there was a significant effect on the relationship between the degree of health cognition, subjective quality of life, and exercise continuity of exercise rehabilitation program participants. In the future, measures to increase the level of health cognition are needed, and it is considered that follow-up studies are necessary in consideration of the individual's physical and social environment.

This study is aimed to verify the impact of health literacy on communication competence in nursing students. 104 nursing students participated in this descriptive research with an online self-reported questionnaire from May 3 to 21, 2021, at a university located in G city. The data were analyzed by two-sample t-test, ANOVA and hierarchical regression with SPSS program. The score of health literacy was 48.62/66 and the communication competence was 59.60/75. More than half perceived that the average reading level of Korean adults was higher than the actual. subjective health status(β=.309, p<.001), health literacy(β=.284, p=.002) and subjective academic grade(β=.235, p=.009) had significant influence on communication competence in the nursing students(F=10.546, p<.001). The explanatory power increased 7.3% more by adding health literacy(F=10.339, p=.002). To enhance communication competence of nursing students, more systematic curriculums to improve health literacy are needed.

The purpose of this study was to investigate the influences of high school students' sexual media literacy awareness and sexual attitude on their gender sensitivity. The subjects of this study were 120 high school students in the city of D, all of who voluntarily agreed to participate in the study. Data were collected from November 28 to December 15, 2022. and analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and hierarchical regression analysis methods using the SPSS 22.0 program. As a result of the study, the influential factors of gender sensitivity were sexual attitude (β=-.317, p<.001), education level of father (β=.305, p<.001), gender (β=.262, p=.001), source of sexual knowledge (β=-.252, p=.001) and awareness of sexual media literacy (β=-.143, p=.045). This study is significant in that it presents academical, practical, and policy recommendation to increase gender sensitivity, which is considered an essential competency in a future society where diversity is emphasized.

응급환자의 생존 가능성은 응급의료체계가 얼마나 잘 갖추어져 있느냐에 따라 결정된다. 과거의 응급체계가 가장 빠른 시간에 환자의 이송함으로서 치료를 받게 하는데 초점을 두었다면 최근은 RFID등의 기술을 이용하여 환자의 상태를 빨리 파악하여 최적의 치료를 받을 수 있는 병원으로 이송할 수 있는 시스템 도입에 초점을 두고 있다. 따라서 응급 환자의 기본적인 정보를 수집한 후 최적의 병원 전 단계(pre-hospital phase)를 수립하기 위해서는 다양하고 이질적인 정보 자원들을 접근할 수 있어야 한다. 또한 응급환자의 기본적인 사고정보를 가지고 최적의 치료를 받을 수 있는 정책을 수립하기 위해 자율적으로 서로 커뮤니케이션을 할 수 있는 시스템이 필요하다. 본 논문에서는 멀티에이전트 기반의 응급 의료 시스템 모델링을 제시하고, 응급환자에 대한 최적의 병원 전 단계를 수립하기 위한 시퀀스를 설명한다.

본 논문에서는 동영상 내용 기반 검색을 위한 표준 인덱스인 color layout descriptor(CLD)에 기반한 새로운 장면전환검출 방법을 제안한다. 제안한 방법은 입력 영상을 $8{\times}8$ 블록으로 나누고, 그 블록을 대표하는 대표컬러를 선택하여 DCT 변환 후 추출된 DC, AC 계수에 가중치를 부여한 다음 슬라이딩 윈도우를 적용시켜 장면 전환을 검출한다. 이러한 방법은 영상의 전체적인 특성과 국부적인 특성을 동시에 반영하므로, 조명변화나 물체의 움직임에 민감했던 기존 대표적인 방법인 히스토그램 기반 방법과 에지 변화율을 이용한 방법들이 가지는 문제점을 보완할 수 있다. 또한 제안한 방법은 비디오 검색을 위한 MPEG-7 의 검색 서술자 중의 하나인 CLD를 이용하는데 이러한 CLD 는 컬러의 공간적 분포를 잘 설명하므로 MPEG-7 을 위한 검색 서술자에 적합한 장면전환검출 및 검색이 이루어질 수 있다. 제안한 방법을 실험한 결과 기존의 방법보다 장면전환 검출율이 높게 나타났다.

The rapid increase of the number of channels makes it hard to find wanted programs from TV. In recent years, the number of channels come up to hundreds with the digital TV arrival. So, it will drive us to the new way of watching TV. In this paper, we introduce a recommendation system for TV programs to overcome this difficulty. We model user profiles and design each module of the system, considering TV environment. Our system gathers basic information from people manually and then updates user profiles automatically by tracking viewing and usage history. As a result, our system recommends daily TV programs based on the changing interest of users. In this paper, we address the problems and solutions by describing our system and the experiment.
