이 연구는 이한주와 이태구(2004)의 후속연구로 제7차 교육과정 체육교과에서 도입된 수행평가의 실제성을 잘 반영한 평가방법인 영상평가를 고전검사이론과 문항반응이론 3모수 로지스틱 모형을 적용하여 검사 양호도를 검증하는 것이 목적이다. 이 목적을 달성하기 위하여 10문항으로 구성된 영상평가를 중학교 2학년 학생 453명을 대상으로 시행하였으며, 피검자의 응답데이터를 이용하여 타당도, 신뢰도, 문항특성, 검사특성을 살펴보았다. 또한, 문항의 편파성을 살펴보기 위해 집단 간 차별적으로 기능하는 문항을 선별하였다. 그 결과, 공인타당도는 .48로 나타났고, 고전검사이론을 적용한 신뢰도 지수(Cronbach`α)는 0.543, 문항반응이론을 적용한 신뢰도 지수(marginal reliability)는 0.558로 나타났다. 고전검사이론을 통한 문항의 분석 결과 1, 3, 7, 8번 문항이 난이도 혹은 변별도 측면에서 양호하지 않은 문항으로 나타났고, 문항반응이론을 통항 문항의 분석 결과 1, 6, 7, 8번 문항이 난이도, 변별도, 혹은 추측도 측면에서 양호하지 않은 문항으로 나타났다. 또한 남녀별 문항특성곡선과 M-H방법을 이용하여 차별기능문항을 선별한 결과 2, 9번 문항이 남, 녀 집단에 따라 차별적으로 기능하는 문항으로 나타났다. 검사정보의 경우 피검자의 능력수준이 0에서-2사이에 가장 높은 값을 산출하는 것을 확인하였다. 이러한 결과를 통해, 이 연구에서는 영상평가의 양호도 정도와 문항의 특성, 영상평가의 양식효과, 검사정보, 차별기능문항에 대한 논의를 제공하고 있다. Lee and Lee (2004) developed a multimedia test program for basketball unit using audio, video, and text to evaluate the 8th graders` knowledge such as rules, regulations, and traditions. The preliminary test contained live video clips of 10 questions. Although Lee and Lee (2004) provided the content validity and test-retest reliability, specific information about the goodness of test has not been reported. Thus, the purpose of this study was to examine goodness of multimedia test program. Participants were eighth graders (N=453) in middle school. Students completed 10 item multimedia test. Using students` test scores, validity, reliability, item and test characteristics were examined. Also, differentially functioning item were explored to examine item bias. Three parameter logistic model in item in item response theory (IRT) as well as classic test theory (CTT) was used. Results showed that concurrent validity was 0.48, reliability coefficient 0.543, and IRT`s marginal reliability was 0.558. Test items were analyzed using the CTT as well as the IRT. The CTT identified as unsual items (i.e., item number 1, 3, 7, and 8) showing lack of discrimination power. The IRT identified item number 1, 6, 7 and 8 were not appropriate in terms of the discrimination power. Test characteristics curve in gender and Mantel-Haenszel method identified differentially functioning item (i.e., item number 2 and 9) indicating two items are in favor of male students. Test information indicated that examinees with ability level between 0 and 2 showed best score. Discussions were provided in terms of the degree of goodness and item characteristics, and discrimination power of multimedia test program.

『조선일보』 연재 <이동백 일대기> 再考

이태화(Tae hwa Lee) 판소리학회 2022 판소리연구 Vol.53 No.-

이 글에서 문제 제기한 쟁점은 크게 세 가지로 정리할 수 있다. 첫째, 이동백의 판소리 스승으로 알려진 김정근과 김세종은 사실 이동백의 음악에 큰 영향을 주지 않았을 가능성이 높으며, 특히 김세종은 직접적인 스승이 아니었을 가능성도 있다. 둘째, 이동백 자신이 구술한 여러 기록에서 비합리적 정황이 자주 등장하는 이유는 자신과 인연이 닿은 당대의 권세가들을 강조하느라고 구체적인 시공간의 정보를 간과했기 때문이라 할 수 있다. 셋째, 통정대부라는 명예직을 제수받은 일은 이동백의 인생에서 중요한 계기가 되었고, 그로 인해 신분제에 대한 모순된 가치관이 드러나기도 했다. 정확한 정보가 아닐 수 있음에도 세상에 나오는 순간 일단 확정되는 설명들. 그리고 머지않아 후속 연구자들이 별 문제의식 없이 수용하게 될지도 모를 연도나 수치들. 게다가 증언이기 때문에 우선 신뢰해야 하는 구술들. 이미 당사자를 다시 만나 바로잡을 수 없게 된 그것들은, 해당 연구 영역에 새로 합류하는 연구자들에 의해 매번 일정한 재검토의 대상이 되어야 한다. 위대하거나 유명한 인물이라는 가치에 눌려 합당하지 않아 보이는 상황들을 간과해서는 안될 것이며, 그것을 적당히 미화하는 일은 더더욱 위험하다. 아직은 단순한 문제 제기에 지나지 않는 쟁점들을 후속 연구로 심화할 계획이나, 이 분야의 신뢰도 높은 자료가 드물다는 것을 알기에 막연한 염려가 앞선다. 음악적 비교 연구를 필자가 감당할 수 없는 점이 무엇보다 아쉽다. 유관 분야의 다른 전공 연구자들도 이 글의 문제 제기를 검토해 주기를 바란다. This article examines certain questions raised by reviewing the biography of Lee Dong-baek, which is often accepted without question because it was written based on his testimony. Lee Dong-baek enjoyed the greatest popularity among the Japanese colonial era's Pansori master singers, and there are very many related extant materials and sound sources. However, there are many differences in the contents of articles written based on interviews with Lee in his old age. Although this is often true of figures from an era when records were not thorough, in the case of Lee Dong-baek, most of the information is from Lee Dong-baek himself, which can indicate a more complex story. It is necessary to understand all the facts and point of interest properly separately, but when integrating them into secondary data, a willingness not to insist upon conclusive finality is needed. This is because the unconfirmed narrative information is confusing not only regarding him but also his colleagues' activities, and further hinders the organization of historical trends in this field. The issues raised in this article can be summarized into three main categories. First, it is highly likely that Kim Jeong-geun and Kim Se-jong, known as Lee Dong-baek’s Pansori teachers, did not have a significant influence on Lee Dong-baek's music, especially because, Kim Se-jong was not a direct teacher. Second, the reason why irrational circumstances often appear in various records dictated by Lee Dong-baek himself is that he overlooked specific times and time information to emphasize the powerful people of the time who had a relationship with him. Third, receiving the honorary position of the Tongjeongdaebu(通政大夫) was an important opportunity in Lee Dong-baek's life, and therefore, he revealed contradictory values about the status system. Explanations are often confirmed as soon as they appear in the world, even though they may not be accurate information, as well as the years and figures that subsequent researchers may soon accept without hesitation. Besides, because it is a testimony, the phrases must be trusted first. We are already unable to correct them because we cannot meet him again. They must be subject to constant review each time new researchers join the research area. We should not overlook situations in which the value of a great or famous person does not seem reasonable, and it is even more dangerous to glorify them properly. It plans to deepen issues that are still nothing more than simply raising problems in follow-up studies, but vague concerns precede knowing that reliable data in this field are scarce. Above all, it is regrettable that I cannot handle the comparative study of music. I hope other researchers in related fields will also consider raising the issues raised in this article.

This paper presents a new forward-viewing mono-camera based obstacle detection algorithm for mobile robots. The proposed method extracts the coarse location of an obstacle in an image using inverse perspective mapping technique from sequential images. In the next step, graph-cut based image labeling is conducted for estimating the exact obstacle boundary. The graph-cut based labeling algorithm labels the image pixels as either obstacle or floor as the final outcome. Experiments are performed to verify the obstacle detection performance of the developed algorithm in several examples, including a book, box, towel, and flower pot. The low illumination condition, low color contrast between floor and obstacle, and floor pattern cases are also tested.

債權者取消權에 관한 小考

李泰喆(Lee Tae-Chiol) 동아대학교 법학연구소 2010 東亞法學 Vol.- No.48

Creditor’s right to cancel (“CRC”) refers to a right through which a creditor may disclaim the effectiveness of his/her debtor’s act and have debtor’s property restored to the original state for the maintenance/preservation of the value of security when the debtor has diminished his/her total properties through legal acts, knowing that such acts cause damage to his/her creditors. Since the original power of CRC is to disclaim the effectiveness of debtor’s disposal of properties, which have already been established, and to have the properties, which have been gained from beneficiary or third party acquirer, restored to the original state, it greatly affects third parties and threatens to harm the safety of transactions. Nonetheless, Korean civil law addresses CRC only in Articles 406 and 407. Consequently, important legal doctrines addressing CRC solely remain in the domain of court cases. Recently, dishonors and bankruptcies have increased due to international economic recession and business recession. Cancelling a deceit that causes harm to creditors and restoring transacted properties to chargeable properties is an important function that not only resolves private disputes, but also establishes legal justice. Furthermore, protecting well-meaning beneficiaries or third party acquirers is also important to protect the safety of transactions. Accordingly, it is appropriate to make a legislative approach to CRC -involving transactions, which are important and diverse. More specifically, it is suggested to create provisions governing the requirements of deceits, and CRS's effects and scope, based on Articles 406 and 407 of the civil law.

본 연구는 아동의 학교적응을 도울 수 있는 방안을 모색하는데 목적을 두고, 부모의 학교참여, 아동의 학교적응과 자아정체감의 관계를 분석하고, 부모의 학교참여와 아동의 학교적응의 관계에서 아동의 자아정체감의 매개효과를 검증하여, 아동의 학교적응을 위해 요구되는 개별 특성을 확인하고자 한다. 이를 위하여 12차년도 한국아동패널 자료를 SPSS 24.0 프로그램을 사용하여, Pearson 적률상관계수, 회귀분석, sobel test를 실시하였다. 이 연구에서 밝혀진 결과는 다음과 같다. 첫째, 부모의 학교참여는 아동의 학교적응과 정적으로 유의미한 영향을 미쳤다. 둘째, 부모의 학교참여는 아동의 자아정체감에 정적으로 유의미한 영향을 미쳤다. 셋째, 아동의 자아정체감은 학교적응에 긍정적 영향을 미쳤다. 넷째, 부모의 학교참여가 아동의 학교적응에 직접적인 영향을 미치기도 하지만, 아동의 자아정체감이 부분매개하는 간접적인 영향력이 있는 것으로 나타났다. 이러한 연구결과를 통해 부모의 학교참여는 자녀의 학교적응을 돕는 중요한 부모역할 중 하나임이 확인되었으며, 부모의 적극적인 학교참여가 가능하도록 사회적 인식, 사회 구조적 변화와 이를 이끌어낼 정책적 지원이 필요함을 시사 받을 수 있었다. The purpose of this study was to examine the relationship among parental school participation, children's school adaptation, and self-identity, and verify the mediating effects of children's self-identity in the relationship between parental school participation and children's school adaptation. The subjects in this study were parents and children who originated from 12th year of the Panel Study of Korean Children(PSKC). The data were analyzed by Pearson's correlation, multiple regression, and the Sobel test using the SPSS 24.0 program. The results of this study were as follows: (1) It was found the there are positive correlations between parental school participation and children's school adaptation. (2) It was found the there are positive correlations between parental school participation and children's self-identity. (3) It was found the there were correlations children's school adaptation and children's self-identity. (4) It was revealed that parental school participation had a direct effect on children's school adaptation, and that children's self-identity partially mediated in relationship between parental school participation and children's school adaptation. These research results confirmed that parental school participation is one of the important parental roles that helps children grow positively.
