The bonding characteristics of MLCCs (multi layer ceramic capacitor, C1608) lead-free solder (SAC305) joints were evaluated through thermal shock test ($-40^{\circ}C{\sim}125^{\circ}C$, total 1,800 cycle). After the test, IMCs( intermetallic compounds) growth and cracks were verified, also shear strengths were measured for degradation of solder joints. In addition, The thermal stress distributions at solder joints were analyzed to compare the solder joints changes before and after according to thermal shock test by FEA (finite elements analysis). We considered the effects of IMCs growth at solder joints. As results, the bonding characteristics degradation was occurred according to initial crack, crack propagations and thermal stress concentration at solder-IMCs interface, when the IMCs grown to solder inside.

시간-주파수 영역 해석법을 이용한 레이더 영상 품질 개선에 대한 연구

정상원(Sang-Won Jung),김경태(Kyung-Tae Kim) 한국전자파학회 2010 한국전자파학회논문지 Vol.21 No.1

본 논문에서는 흐려진 ISAR(Inverse Synthetic Aperture Radar) 영상의 회전 오차를 보상하기 위해 시간-주파수 영역 해석법을 이용한 회전 이동 보상(rotational motion compensation) 알고리즘을 제시한다. 실제의 비행 환경에서는 표적의 회전이나 가속 등의 움직임으로 인하여 도플러 주파수 천이가 시간에 따라 변하게 되고, 이에 따라 회전 오차(motion error)가 발생한다. 본 알고리즘으로 도플러 주파수 영역 방향으로 흐려진 ISAR 영상을 개선한다. 시뮬레이션 결과, 기동하는 표적에 회전 오차가 있을 경우에 시간-주파수 영역 해석법은 흐려진 레이더 영상의 품질을 개선하는데 효율적임을 알 수 있다. In this paper, an efficient algorithm is developed to perform target rotational motion compensation to achieve the clear inverse synthetic aperture radar(ISAR) image. The algorithm is based on a time-frequency technique. This algorithm provides an efficient method to resolve the blurring image caused by the time-varying behavior of the target scattering centers and leads to a well-focused ISAR image. Results demonstrate that the time-frequency techniques can improve the blurring ISAR image when an aircraft is in complex motion, such as maneuvering, rotation and acceleration.

현행 교과서를 통해 살펴본 <홍길동전> 교육의 현황과 과제 -중학교 국어 교과서를 중심으로-

정상원 ( Jung Sang-won ) 한국고전문학교육학회 2024 고전문학과 교육 Vol.55 No.-

이 논고에서는 현행 중학교 국어 교과서를 대상으로 <홍길동전> 교육의 현황을 점검하고 과제를 제시하고자 했다. 주지하듯 <홍길동전>은 오랫동안 한국 문학사와 교육 현장에서 공히 높은 가치를 인정 받아온 바 있다. 일종의 정전의 지위를 누려오면서 그동안 적지 않은 연구가 수행되었으며, 이는 교육과 관련한 논의에 있어서도 마찬가지이다. 그럼에도 <홍길동전> 교육의 현재적 면모를 다루고 있는 연구는 미진한 상태인데, 대부분 교과서 수록 및 교육 양상을 단편적으로 논의하는 데 머물러 있다. 또한 <홍길동전>을 본제재로 수록한 중학교 국어 교과서를 본격적으로 다룬 선행 연구도 3종의 교과서 가운데 1종의 교과서만을 특정한 문학교육관에 입각하여 분석하고 교수-학습 방안을 논의하고 있을 뿐이다. 이에 지금으로서는 <홍길동전> 교육의 전모를 파악하기 어렵다. 만일 고전의 고전성이 그때마다의 지금-여기의 우리에게 어떤 가르침을 부여함으로써 삶의 방향을 제시한다는 사실로부터 형성되며, 이를 토대로 교육적 가치 및 문학사적 가치가 상보적인 관계를 맺으면서 산출된다는 점에 동의한다면, <홍길동전> 교육의 현재적 모습을 살펴보는 일은 문학 연구뿐만 아니라, 교육의 영역에 있어서도 유효한 일이다. 물론 이는 <홍길동전> 교육의 발전적 방향을 모색하는 작업에 있어서도 타당하다. 한편 <홍길동전>을 본제재로서 수록하고 있는 현행 교과서는 3종인데, 공교롭게도 중학교 1학년부터 3학년에 걸쳐서 한 권씩 고르게 수록되어 있다. 또한 각각의 교과서에 수록된 단원의 성취 기준도 각이하다. 이는 의도적으로 위계화된 것은 아니지만, 다양한 성취 기준을 반영하여 한 작품을 교육하는 양상을 살펴볼 수 있을 뿐만 아니라 넓게는 중학교에서 이루어지고 있는 고전소설 교육의 면모를 조망할 수 있다는 점에서 연구사적 의미를 찾을 수도 있다. 이러한 문제 의식에 따라 본고는 본제재로서 <홍길동전>을 다루고 있는 2015 개정 중학교 국어 교과서 모두를 대상으로 논의를 개진하고자 했다. 구체적으로 이들 교과서를 읽기 전, 중, 후 활동의 세 측면으로 나누어 수록 단원 및 학습 목표, 본문 수록 양상, 날개의 정보와 질문, 학습 활동의 내용, 소·대단원 마무리 활동 등을 살펴보면서 <홍길동전> 교육의 현황과 과제를 논의했다. 논의의 결과, 갈등과 관련한 성취 기준에 따라 구현된 교과서는 학습자가 교과서에 수록된 갈등의 내용 및 성격을 명확히 이해하기 어려운 대목이 있다는 점, 갈등의 해결로 보기 어려운 장면들도 모두 갈등이 해결된 것으로 다룬다는 점, 어떤 갈등을 해결한 것으로 간주하더라도 해결 방식이 교육적이지 못하다는 점과 관련하여 수정 및 보완이 요청된다는 점을 밝혔다. 다음으로 소설에서 ‘보는 이’에 초점을 맞춘 교과서는 <홍길동전>과 직접적으로 연관이 있는 읽기 전 활동을 마련하고, 교과서 본문으로 수록한 장면과 날개의 정보 및 질문을 소단원의 학습 목표와 긴밀히 연계된 방향으로 보완할 필요가 있다. 마지막으로, 사회·문화적 배경과 관련한 성취 기준에 따라 집필된 교과서는 오늘날의 사회·문화적 배경과 작품 속 사회의 모습을 비교 고찰하는 학습 활동을 <홍길동전>의 학습을 통해 형성할 수 있는 지식과의 연계성을 고려하여 보완할 필요가 있다. 또한 시공간적 격절의 문제와 관련한 학습 활동과 관련하여 그때-거기와 지금-여기의 현사실성을 고려하여 더욱 섬세한 작업이 요청된다. 기실 2022 개정 교육과정이 이미 발표된 현재의 시점에서 이러한 논의는 다소 늦은 감이 없지 않다. 그럼에도 본고의 작업을 토대로 현행 교과서가 가지고 있는 교육적 효과를 발굴하거나, 보완 혹은 수정이 필요한 문제들을 자세히 살펴봄으로써 <홍길동전>의 발전적인 교육을 구상하는 데 작은 보탬이 되기를 바란다. 뿐만 아니라 최근 교육과정이 개정될 때마다 국어과에서 설 자리가 급격하게 줄어들고 있는 고전문학의 가치를 다시 보여주고 점검하며 교육적으로 설계하는 작업에도 도움이 되기를 바란다. In this article, we examine the status of Honggildongjeon education and its tasks by targeting current middle school Korean language textbooks. Honggildongjeon has long been recognized for its high value in Korean literary history and education. Numerous studies have been conducted thus far on enjoying the status of a type of power outage, and this is the same for discussions related to education. Nevertheless, research dealing with the current aspects of Honggildongjeon education is incomplete, and most of them only present fragmentary discussions on textbook content and educational aspects. In addition, only one of the three textbooks is analyzed according to a specific literary education perspective, and teaching-learning plans are discussed in advance, including Honggildongjeon as a key sanction. Currently, it is difficult to grasp the complete picture of Honggildongjeon education. If we agree that the classical nature of a classic is formed from the fact that it presents the direction of life by giving us a certain teaching here and now, and that educational and literary values are produced in complementary relationships based on this, examining the present aspect of Honggildongjeon education is effective not only in literary research but also in education. This is also valid for work seeking the developmental direction of Honggildongjeon education. The three current textbooks contain Honggildongjeon as the main sanction; unfortunately, one version is used throughout the first to the third grades of middle school. The grading standards of the units in each textbook also differ. Although this is not intentionally sequenced, it is possible to examine aspects of how a work is taught based on its grading standards, and thereby broadly review how education about classical novels is conducted in middle school. Accordingly, this paper presents discussions of all the 2015 revised middle school Korean language textbooks dealing with Honggildongjeon. The current status and tasks of Honggildongjeon education are discussed by examining the unit and learning goals, pattern of the text, information and questions on the wings, content of learning activities, and completion activities of small and university units. It was found that the textbook implemented according to the achievement standards related to conflict revealed that there are areas in which learners find it difficult to clearly understand the content and nature of the conflict in the textbook, that scenes that are difficult to see as resolving conflicts are treated as resolved, and that the methods of solution are not educational, even if any conflict is considered resolved. Next, the textbook focusing on “the viewer” in the novel needs pre-reading activities directly related to Honggildongjeon, and the information and questions on the scenes and wings contained in the main text must be supplemented in a direction closely linked to the learning goals of the sub-unit. Finally, textbooks written according to achievement standards related to social and cultural backgrounds need to supplement the learning activities that compare and examine the appearance of society in the work with the current social and cultural background in consideration of the connection with knowledge that can be formed through Honggildongjeon. In addition, more detailed work is required considering the situation then-there and now-here in relation to learning activities related to the problem of spatiotemporal segregation. In fact, now that the 2022 revised curriculum has already been announced, this discussion is somewhat late. Nevertheless, I hope that this paper will make a small contribution to the conception of the developmental education of Honggildongjeon by revealing the educational effects of the current textbook or by encouraging a detailed examination of the problems that need to be supplemented or revised. In addition, whenever the curriculum is revised, it is hoped that it will help convey and cultivate the value of classical literature, which is rapidly decreasing in Korean language departments.

정상원(Sang-Won Jung),윤홍주(Hong-Ju Yun) 한국내러티브교육학회 2020 내러티브와 교육연구 Vol.8 No.3

교육 현상을 바라보는 하나의 렌즈로서 교사의 삶은 많은 관심을 받아왔다. 그리고, 이러한 흐름 속에서 다양한 교사들의 삶이 탐구되어왔다. 이러한 관점에서 이 연구는 초임교수의 삶과 그것에 기반한 주관성을 쿠레레 방법을 통해 탐구해보고자 한다. 연구의 결과, 한 초임교수의 주관성은 열등감과 극복으로 구성되어 있었으며, 이러한 주제는 그의 삶의 전반에 걸친 교육적 경험을 통해 형성되어왔다. 이러한 주제들은 열등감 배우기와 외면하기, 열등감 대면하고 극복하기, 경계에서 서서 나의 가치를 증명하기, 열등감을 삶의 원천으로 삼기로 종합해 볼 수 있었다. 극복노력, 이러한 연구의 결과는 학교의 개선과 교육과정 연구의 개선에 의미 있는 시사점을 제공해 줄 수 있을 것이다. The life of a teacher has received a lot of attention as one of the lenses seen as an educational phenomenon. Under this attention, various forms of teachers lives have been studied. This study seeks to explore the life of a professor based on the subjective Currere method. Through examining the educational experiences of the professor s life, the subjectivity of the professor was established and consisted of the professor s inferiority complex and overcoming. These subjectivity could be summarized as learning and disregarding inferiority, confronting and overcoming inferiority, proving self-affirmation on the edge, and living with inferiority as a source of life. The results of this study may have implications for the improvement of schools and the curriculum research society.

정상원(Sang Won Jung),정수진(Su Jin Jung) 한국사회체육학회 2004 한국사회체육학회지 Vol.0 No.22

The purpose of this study is to investigate the effect of interest in, participation in, exhortation to, and attitude toward the sports shown by the friends and teachers and the exhortation from the sports association and mass media focused on the parents, brothers and sisters who are the superintendents of the socialization which has a great effect on the children`s intelligent, affective, and behavioral development. To achieve this purpose, a survey using a questionnaire is carried out to the elementary school students on the fifth and the sixth grades in Kyeongsangnamdo, and the questionnaires collected from them were analyzed using the SPSS 12.0 for Windows. The results of this study by this purpose and method are like followings. At first, as a result of investigating the degree of participation in sports of the superintendents of socialization, it was indicated that the superintendent who has the highest interest in sports was man teacher, then male friend secondly and father in sequence. In the question of the degree of participation in sports, the man teachers was answered that they had the highest degree of participation in sports, then male friend secondly and brother in sequence. In the question of the degree of exhortation to sports, the fathers was answered that they had the highest degree of exhortation to sports, then the mothers secondly and the man teachers in sequence. In the question of attitude toward sports, the fathers were shown as they had the highest degree of attitude toward sports, then the mothers secondly and the man teachers in sequence. In the question of the degree of practice in life, they practiced and did various activities most through an institution both in and out of school. And it was indicated that the boy students practiced more than the girl students in all of the activities except the club activity out of school. Lastly, as a result of investigating the effect of the superintendents of socialization on the elementary school students` lives with practice, as they were man students or had a higher subjective social level, they practiced more in life both in and out of school. And as the father`s attitude toward sports was good, they practiced more in life in school. The mother`s participation in sports did not have any great effect on the elementary school students` lives with practice, but it was indicated that as the mother did not exhort to sports, the students did more club activities in school. In addition, as the brothers exhort to sports much, as the attitude toward sports was good, and as the sister`s attitude toward sports was good, they had a significant effect on the life with practice in school, but they didn`t have a significant effect on the life with practice out of school. Furthermore, it was indicated that as male friends participated in sports more, exhorted them to sports more, and had a good attitude toward sports, the students practiced more in school, and as the male friends exhorted to sports more, they practiced more out of school. It was appeared that as the female friends had a good attitude toward sports, they practiced more both in and out of school. As the man teacher exhorted the students to sports more and had a good attitude toward sports, and the woman teachers exhorted the students to sports more, the students practiced more in school. Both the man teacher and the woman teacher didn`t have any great effect on the life with practice out of school. Finally, it was appeared that as there is more exhortation from the sports associations and mass media, the students practiced more both in and out of school. As shown above in the survey, it can be indicated that the male friends` exhortation to sports, the female friends` attitude toward sports, and the exhortation from the sports associations and mass media have the greatest effect on the life with practice of the elementary school students.
