전쟁영화 속에 담긴 어린이 -2019∼2020년 BIKY(부산국제어린이청소년영화제) 상영작을 중심으로-

김상화 ( Kim Sang-hwa ) 방정환연구소 2020 방정환연구 Vol.4 No.-

영화는 전쟁과 냉전을 소재로 앞 다투어 많이 다룬다. 흥미로운 얘깃거리와 박진감 넘치는 화면을 마음 놓고 만들 수 있기 때문이다. 전쟁의 아픔, 그 속에서의 고뇌와 용기, 비인간성과 같은 것을 보여주는 영화는 이미 많다. 그 중에 어린이가 등장하는 장면도 많다. 어린이를 앞세우면 감정을 더 짙게 전할 수 있고 전쟁을 다른 시선으로 만들기가 손쉽기 때문이다. 그렇지만 어린이를 위해 전쟁을 소재로 다루거나 어린이가 중심을 이루는 전쟁영화 는 그리 많은 편이 아니다. 뿐만 아니라 국내 제작 영화는 거의 없다고 봐도 좋다. 있었다면 반공을 부추기는 애니메이션 영화이거나 눈물샘만 자극하는 신파조의 영화를 넘지 못한다. 그럼에도 ‘전쟁 영화 속의 어린이’를 다루어 보자는 것은 70년 동안 계속되고 있는 한국전쟁 속에서, 오늘에 되짚어 볼 의미가 있다고 여겼음직하다. 이 글에서 다루는 영화는 부산국제어린이청소년영화제(BIKY)에서 상영한 장편 영화 2편과 단편 2편이다. <87명의 아이들>은 2019년 ‘너와 더불어’ 섹션에 초청하였고, <나 치의 아이들>은 2020년 ‘다름 안에서’, <땋은 머리>는 ‘아시아 파노라마’, <헬멧>은 ‘경 계를 넘어서’ 섹션에 초청 상영되었다. 영화는 우리의 세상사를 폭넓게 다룬다. 돈벌이가 목적이라 해도 세상사를 다루지 않고는 거친 재미도 줄 수 없다. 그 덕분에 영화는 좋은 생각을 나누기도 하지만 나쁜 생 각을 가려 볼 수 있게도 한다. 나아가 감성을 돋궈내는 역할도 하기에 더없이 좋은 매체 이다. 그러나 비판 없이 파묻히면 매체의 노리개일 뿐이다. 앞서 살핀 전쟁 영화 속의 어린이에서 영화가 어떤 태도를 가지고 어린이를 담는가에 따라 어린이는 달라질 수 있다. 모든 것은 어른의 문제다. 어른이 성찰하고 각성하고 실천을 게을리 말아야 하는 이 유이다. Many movies deal with wars and the Cold War a lot as if they make a head-to-head. It is because the filmmakers can create as many interesting stories as they want and they can make scenes full of excitement to their heart’s content in their work. There are already plenty of movies that show the pain of war, the agony and courage in war and the inhumanity. Among those movies, there are many scenes where children appear since children can convey their emotions more deeply and war could be easily turned into different perspectives. However, there are not many war movies that depict war for the sake of the children or focus on children themselves. As well as, it is fair to say that there are few films produced domestically. Even if there have been, it would not have been more than animated films that encourage anti-Communism or movies by Neo-fascism that only stimulate tear glands. Nonetheless, it would be meaningful to look back on the Korean War which has been going on for over 70 years by even today to deal with ‘Children in War Movies’. The films covered in this article are two feature films and two short films, which were screened at the Busan International Kids and Youth Film Festival (BIKY). “87 Children” was invited to the 2019 ‘Staying Together’ section, “The Nazi Children” to the 2020 ‘Embrace the Difference’ section, “Braids” to the ‘Asian Panorama’ and “The Helmet” was invited to the ‘Beyond the Boundary’ section. Movies cover a wide range of our world history. Even if making money is the main purpose of film industry, no film can entertain the audience only with rough excitement without dealing with world affairs. Thanks to that, movies help to share good thoughts and make it possible for the audience to filter what bad thoughts are. In addition, there is nothing like a movie when it comes to playing a role to stimulate emotions. However, if being buried without criticism, a movie is nothing more than a plaything for media games. Image of the children shown in the previously mentioned ‘Children in War Movies’ can be changed depending on what attitude the films show to describe children. Everything is a matter of adults. This is why grown-ups should reflect, get awaken and put their thoughts in practice with more diligence.

김상화(Sang-Hwa Kim),김병하(Byung-Ha Kim),최우각(Woo-Gak Choi) 한국기계가공학회 2012 한국기계가공학회지 Vol.11 No.4

Very important content in performance evaluation of machine tool is positioning accuracy and repeatability precision measurements of feed mechanism. A study analyses the measurement method and uncertainty factors by ISO-based test method. Reliable results can’t be derived without the notion of measurement uncertainty. The reason is that the measured value includes a lot of uncertain factors. Finding the factor that affects the measurement of parameter is important for estimation of measurement precision. In this paper, the evaluation of uncertainty analysis about positioning accuracy and repeatability precision measurements of high precision feed mechanism is presented to evaluate the important factors of uncertainty.

김상화(Sang-Hwa Kim),김병하(Byung-Ha Kim),진용규(Yong-Gyoo Jin) 한국기계가공학회 2012 한국기계가공학회지 Vol.11 No.3

The spindle unit is a core part in high precision machine tool. Rotation accuracy of spindle unit is needed for high dignity cutting and improving the performance of machine tool. However, there are many factors to effect to rotational error motion(rotation accuracy). This study studied how rotational error motion is variation when unbalance amount is variation. Rotation accuracy of initial spindle unit is decided depending on parts and assembly such as bearing. When it is rotation, vibration and noise is appeared depending on volume of unbalance amount, so it works to decrease unbalance amount. The purpose of the study tests that unbalance amount how much effects to initial rotation condition. The result of the study shows that accuracy of parts and assembly is highly necessary to reach high rotation accuracy and unbalance amount hardly effects to initial rotation accuracy. However, it shorten spindle"s life because vibration and noise is increasing by increasing unbalance amount and we can expect situation that rotation accuracy is falling by long time operation.

김상화(Sang Hwa Kim),방정숙(Jeong Suk Pang) 학습자중심교과교육학회 2011 학습자중심교과교육연구 Vol.11 No.4

본 연구는 현행 수학과 교육과정에서 강조하고 있는 수학적 의사소통 능력 신장을 위한 수업 중 표현중심 수학 수업에 대해 살펴보았다. 초등 교사들은 학생 개개인의 수학적 사고나 특성을 살려 다양한 표현을 할 수 있도록 수업을 하는 것이 중요하다고 인식하지만 실제 수업에서는 잘 이루어지지 않는다. 이에 본 연구에서는 2·4·6학년에서 표현중심의 수학적 의사소통 수업을 구현하고 표현중심 성취요소 도달 정도와 학생들의 표현 산출물을 분석하였다. 분석 결과를 토대로 표현중심 수학수업을 구현할 때의 교사 역할에 대한 시사점을 논의하였다. This paper analyzed three mathematics teaching practices focused on representation as a way to fostering students mathematical communication ability which has been emphasized in recent mathematics curricular revisions. Elementary school teachers tend to recognize easily the importance of multiple representations on the basis of individual students mathematical thinking abilities or characteristics, but often report considerable difficulties in implementing such an idea in their actual classrooms. Given this, this paper first illustrates how three teachers implemented mathematics instruction focused on representation in their second, fourth, and sixth grade classrooms respectively. It then analyzes how learning expectations related to mathematical representation were attained in each classroom. Students various products were additionally analyzed in terms of the diversity of representational forms and thinking processes through mathematical representations. This paper finally discusses the role of a teacher for effective mathematics teaching focused on representation.

The rotation of a spindle unit must be accurate for high-quality machining and toimprove the quality of the machine tools.Therefore, the propermeasurement of the rotation accuracy and ensuring a proper analysis are very important. Separateprocesses are necessary because spindle errorsand roundness errorsassociated with the test balls can both factor into the measured rotation error values. We used three methodsto discern test ball errors and analyzedwhich could be deemed as the most proper technique in a test of the rotation accuracy of the main spindle of a machine tool.
