우리나라에서 공과 대학 학생들의 효율적인 교육을 위하여 유사학과의 계열별 통폐합이 추진되고 있는 바, 현 시점에서 미국에서 논란되어지고 있는 전기공학 교육과정의 내표하고 있는 많은 문제점이 미국 뿐만 아니라 한국에서도 공통적인 문제점들임을 감안할 때 미국의 여러 기관, 학교 등에서 연구, 계획, 실행되어가고 있는 교과과정에 대해 그 방향을 정리 검토하여 한국의 전기공학 교육발전에 참고하려 한다. 미국 대학에서 일반적으로 시행되고 있는 교과과정 및 제도는 한국과 거의 유사하다고 볼 수 있다. 그러므로 일상적인 제도에 관한 것을 포함시키지 않고 현재의 공통적인 문제점들을 개선하고자 하는 새롭고 창의 적인 개혁 방안들을 중심으로 정리하였다. 이 글에서는 한국 사회의 현실성이란 변수를 감안하지 않고 미국의 전기공학교육의 방향을 객관적으로 검토하는데 촛점을 두었다.

The electromagnetic properties and microstructures of the basic composition of (Ni$\sub$0.2/Cu$\sub$0.1/Zn$\sub$0.2/)$\sub$0.5/ (Fe$_2$O$_3$)$\sub$0.5/ were invested by changing of SO$_4$, Cl and NO$_3$ series. We were prepared by coprecipitation method and sintered at temperatures 950$^{\circ}C$, 1150$^{\circ}C$, l350$^{\circ}C$, respectively. When sintering at temperature 950$^{\circ}C$, Cl and NO$_3$ series became perfection sintering. On the other hand, SO$_4$ series showed perfection sintering at temperature 1150$^{\circ}C$. According to particle size analysis result, higher magnetic permeability and magnetization value were observed by Cl series than SO$_4$ or NO$_3$ series.

This study aims to explore the present condition of job preparation of students in the department of physical education in depth so that convergence talents with professional physical education abilities can be trained and physical education majors can establish themselves in adverse conditions such as the reduction of the entrance quota and a lack of cases of research on job training in the departments related to physical education by the college evaluation of the Ministry of Education and to present a direction of career training. In order to analyze the relationships among sub-factors according to the level of perception of physical education-related majors, methods such as MANOVA and correspondence analysis were used. The results obtained through the research are as follows: First, it turned out that it is important to carry out career training in advance, considering physical education-related college students' aptitude and talent by grade. Second, it turned out that it is important to alleviate the problem of employment barrier in the preparation for career fast. Third, it turned out that it is important for us all to make efforts to expand the types of physical education-related employment and provide opportunities.

This study researched methods for coping with safety accidents by university students, after considering the situation of safety education by universities in Korea. For this study, a survey of 411 students of universities in the cities of Gwangju and Daejeon was conducted. According to the results, the ratio was high for answers such as willingness to participate in safety education beginning with the departments of engineering, art and physical training, education, art and humanity, social sciences and natural sciences, and medical sciences. It was found that university students most preferred first aid among the contents of safety education. University students of all departments answered that they had experienced safety education, but were afraid to be embarrassed in the case of actual safety accidents, as was found through the results of investigations of their awareness of coping methods with safety accidents. It was verified that many times their suffered skin and other wound in an earlier safety accident that they had experienced. This study suggests that safety education needs to be accomplished in the university curriculum, predicting and practicing for causes and factors of danger in advance, in order to improve the level of safety awareness and safety competence among university students.

This study was undertaken to analyze the relationship between the Big-five personality factors of undergraduate students and Creativity Convergence Competency. Totally, 511 students attending private colleges in G province were surveyed for their competences. Using the SPSS 22.0 program, all collected data were analyzed by one-way ANOVA, Pearson's correlation analysis, and regression analysis. The following results were obtained. First, personality extraversion and Creativity Convergence Competency differed in all the major factors examined. Second, higher the interpersonal abilities, higher was the ability of core convergence. Third, extraversion and sincerity among the Big-five personality factors were significant predictors of Creativity Convergence Competency. In conclusion, we found that the Big-five personality factors are important to be considered for strengthening the competence of students.

본 연구의 목적은 최근 자본비용 추정에 대한 신뢰성 및 정확성에 대한 비판에도 불구하고 주로 미국과 일본 등을 중심으로 기업전체를 대상으로 한 과거의 연구에서 벗어나 한국의 상장기업을 대상으로 좀 더 미시지적이고 정교한 자본비용을 추정하는 데에 있다. 1981년 이후 1994년까지 계속 상장되어온 190여개 상장업체의 재무제표를 사용하여 각 기업별 자본비용을 추정함으로써 산업별(업종별) 그리고 5대(大) 계열기업군, 6대(大)${\sim}$30대(大) 계열기업군, 기타 대기업, 그리고 중소상장기업 등 기업규모별에 따른 자본비용의 정도를 비교 분석하였다. 자본비용의 추정과정에 있어서도 가능한 한 각 개별기업의 재무제표 항목들을 자본비용의 개념에 적합하도록 재구성하고, 법인소득세율을 이익수중에 따라 차등 적용하는 등 기존의 자본비용의 추정에 관한 연구에 비해 좀 더 정교한 자본 비용의 추정을 시도하였다.

Sco OB1의 핵심성단 NGC 6231를 호주 Siding Spring 천문대 1m 망원경을 사용하여 -40'${\times}$40' 영역을 관측하였다. 측광자료를 바탕으로 성단의 반경, 성간소광 법칙, 나이 및 초기질량함수를 결정하였다. 성단의 반지름은 구성원의 질량에 상관없이 거의 10' ($R{\approx}4.6pc$)으로 동일한 값을 보였다. 전체적으로는 정상적인 성간소광 법칙을 따르지만, 성단의 중심으로 갈수로 큰 $R_V$를 보여주며, 이는 과거에 있었을 것으로 추정되는 초신성의 효과로 추정된다. 질량이 큰 별과 X-선으로 선택된 성단의 전주계열성은 비슷한 평균나이를 보이지만 전주계열성은 훨씬 큰 나이분산을 보였다. 성단전체 초기질량함수의 기울기는 Salpeter 초기질량함수의 기울기와 매우 유사한 ${\Gamma}$=-1.1${\pm}$0.1을 보였으며, 성단 중심거리에 따른 초기질량함수의 기울기는 -1.0${\pm}$0.2에서 -1.8${\pm}$0.5까지 체계적으로 변화를 하였다. 질량이 큰 O형 별의 쌍성비율이 중심거리에 따른 변화를 보이지 않음에 비추어 볼 때, NGC 6231의 질량분리 양상은 역학적 진화의 결과가 아니라 원초적 질량분리현상으로 결론을 내릴 수 있다.

The college's beauty department, which has a globalized education system that breaks away from the uniform beauty concept, can dominate in the fierce competition with other schools, and the development and vitalization of the department is guaranteed. In addition, research on the department name is very necessary to establish internal and external PR strategies for affiliated departments and departments and to analyze the direction of realistic beauty education. Accordingly, as a result of analyzing the trends of the department and department name by classifying the universities in Yeonghonam into four regions, the departments belonging to each region of the beauty department showed the most belonging to the natural science and arts and sports departments. In addition, the names of beauty departments by region are Busan and Gyeongnam, Daegu and Gyeongbuk, Gwangju and Jeonnam, and Jeonbuk with 5 beauty departments (29.41%), 3 beauty design schools (13.04%), and 8 beauty and beauty departments. (50.00%), beauty design departments, 2 schools (33.33%). This study makes it possible to cultivate professional beauticians who cultivate an artistic and creative sense that meets the educational goals of beauty education, and it is expected that it will be provided as a very necessary basic data for the division of departments or change of department name according to detailed majors.

SRAM-based FPGAs mainly used to develop and implement high-performance circuits have SRAM-type configuration memory. Soft errors in memory devices are the main threat from a reliability point of view. Soft errors occurring in the configuration memory of FPGAs cause FPGAs to malfunction. SEM(Soft Error Mitigation) Controllers offered by Xilinx can mitigate the influence of soft errors in configuration memory. SEM Controllers use ECC(Error Correction Code) and CRC(Cyclic Redundancy Code) which are placed around the configuration memory to detect and correct the errors. The correction is done through a partial reconfiguration process. This paper presents the availability analysis of SRAM-based FPGAs against soft errors under the protection of SEM Controllers. Availability functions were derived and compared according to the correction capability of SEM Controllers of several different families of FPGAs. The result may help select an SRAM-based FPGA part and estimate the availability of FPGAs running in an environment where soft errors occur.

잠수함이 가장 취약한 시기는 잠수함이 스노클이나 잠망경 운용을 위하여 잠망경 심도로 항해할 경우이며, 이때에는 비음향 탐지센서인 레이더와 광학, 사람에 의한 시각에 탐지될 확률이 매우 높다. 따라서 본 논문에서는 이러한 상황에서 탐지되는 취약성을 극복하고자 잠수함 마스트 및 잠망경 부분에 비음향 스텔스를 적용하고자 한다. 먼저 비음향 탐지센서에 대해서 조사하고, 그에 따른 스텔스 기법을 분야별 분석하여 최적화한 결과 다층형 구조로 선체표면부터 RAM layer, IR layer, Camouflage layer 구조로 각각 RAM layer는 자성재료인 페라이트계열로 3~5mm, IR layer는 Ceramic 또는 Nickel 계열로 1~2mm, Camouflage layer는 군청색 계열 페인팅을 제시하였다.
