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.

대다수의 한국 학생들은 사교육 영역에서 선행학습을 하고 있다. 이러한 선행학습은 학교에서의 학습을 질을 떨어뜨리는 요인으로 비판받고 있다. 이러한 비판은 심층적인 경험적 연구에 기초하지 않은 상황에서 제기되고 있다. 이에 이 연구는 질적연구방법을 통해 선행학습이라는 한국의 독특한 교육/학습 현상을 이해하고자 하였다. 연구 결과로서 이 연구는 사교육 기관에 따른 선행학습의 형태와 선행학습의 유형을 분석하였으며, 이러한 선행학습이 가지는 교육과정적 특징을 규명하였다. 나아가 선행학습이 학생들의 학습에 미치는 영향을 논의하였다. 이 연구는 사교육에서 이루어지는 선행학습의 실체를 보다 명료하게 밝힘으로써 한국 학생들의 학습과 그들의 학습문화를 이해하고 나아가 우리나라 교육 발전을 위한 시사점을 제공할 수 있을 것이다. Most Korean students participate in preview learning in shadow education space. Preview learning has been attributed to damaging the quality of students’ learning in school classes. Yet, such criticism is not grounded by in-depth understanding of the phenomenon and students’ experience in it. Thus, this study is to understand preview learning through qualitative research methods. As a result, this study sought to ascertain the forms of preview learning at different shadow education types and discusses the curricular characteristics of the forms of preview learning. Furthermore, this study discusses the effects of preview learning on individual students’ learning. Additionally, this study offers implications for educational development in South Korea and understanding students’ learning culture.

의도주의와 반의도주의의 현재적 논쟁에 대한 철학적 고찰

정상원 ( Jung Sangwon ) 고려대학교 한국어문교육연구소 2022 한국어문교육 Vol.39 No.-

본고는 의도주의와 반의도주의의 현재적 논쟁을 철학적으로 고찰했다. 이는 해석의 처소, 해석의 조건, 해석의 구조, 창작자의 존재에 관한 논의를 통해 이루어졌다. 논의의 결과 온건한 실제 의도주의의 주장과는 달리 인간은 공통성 안에 존재하며, 그런 한에서 해석에 있어서 공적인 요소의 바깥을 상정하는 사유는 수정되어야 한다. 한편 시간성을 가지고 역사적으로 존재하는 인간의 존재론적 구조에 주목한다면, 창작물은 해석이 수행되는 그때마다 새로운 의미를 부여받는다. 따라서 어떤 유일한 의미를 가질 수 없는데, 이것은 의의가 아니라 바로 창작물이 갖는 진정한 의미이다. 창작자의 의도를 파악하는 추상적인 작업은 가능하지 않을 뿐만 아니라, 그것이 일종의 외적 반성에 불과하다는 점에서 바람직한 이해도 아니다. 그런 점에서 창작자를 창작물의 독점적인 주인으로 옹립하고 창작자의 의도가 창작물의 의미를 확정한다는 사유는 수정되어야한다. 본고의 논의가 예술 작품을 향유하는 현상 및 이해와 해석의 본성을 재조명하고 재규명하는 작업에 도움이 되기를 바란다. In this paper, we philosophically studied the recent debates between Intentalism and Anti-Intentalism. We did this through discussions regarding the place of interpretation, the conditions of interpretation, the structure of interpretation, and the creator. As a result, contrary to the argument of ModerateActual Intentivism, humans exist within Gemeinsamkeit, so the idea of outside the public element in interpretation must be modified. On the other hand, if you pay attention to the historical ontologisch structure of humans with Zeitlichkeit, the creation has a new meaning whenever the interpretation proceeds. Therefore it cannot have only one meanining, which is not the signification, but the true meaning of the creation. Abstract work to grasp the creator's intentions is not only impossible, but it is not a desirable understanding in that it is only äuβere Reflexion. Therefore, the reason that the creator is the exclusive owner of the creation and the creator's intention confirms the meaning of the creation should be revised. It is the auther’s hope that this discussion will be of help in re-examining and clarifying the nature of the phenomenon, understanding, and interpretation of art works.

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.

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.
