새로운 子宮內避姙裝置인 Copper T의 效率에 關한 硏究

申在鉉,李性寬 慶北大學校 醫科大學 1973 慶北醫大誌 Vol.14 No.1

Lippes' loop has widely been used as an effective contraceptice device today, but the untoward side effects which cause a high drop-out rate have been an obstacle in promoting the family planning program in rural Korea. The major side effects which prevent continuous use of the Lippes' loop were recognized as pain and bleed ingdue to endometrial compression and myometria distension. To minimize the side effects, Tatum improved a device having a small surface are and a shape of T to conform with the endometrial cavity shich exert minimal pressure on the myometrium. With the Tatum's plan T, the side effects have been reduced markedly, but the contraceptive effect was not satisfactory. Tatum and Zipper mae further improvement of the loop with metalic copper which exerted a potent antifertility effect. When placed n the endometrial cavity of animals, the result of clinica traial with Copper T was satisfactory in antiferility and other side effects in minmizing. To assess the effect and acceptability of the "Copper T" by the community, frequency of pregnancy, spontaneous expulsion and removal by various side effects were observed. 1. The rate of various side effects with Copper T was 35 percent which is comparable with the Lippes' loop. The major side effects observed were pain and bleeding which developed moslty within eight weeks of insertion. 2. The rates of pregnancy, spontaneous expulsion and removal due to side effects at the end of 12th month were 0.3, 5.9 and 23.0 per cent respectively, giving a total drop-out rate of 29 percent. The total event rate as well as the removal rate by various side effect observed in the study was higher than result in United State however the rate was significantly lower significantly lower that of the Lippes' loop in Korea. 3. The cumulative total continuation rates at the end of 9th and 12th months were 72 and 71 percent respectively which were considerably lower than that of the U.S. study, however were higher than that of the Lippes' loop in Korea.

The purposes of this study were to compare the bleaching efficacy of sodium perborate when mixed either with Superoxol or distilled water and to evaluate the efficacy of different location of intracoronal base on the presence of apical leakage of tested bleaching agents. Forty eight extracted human permanent incisors were stained via whole blood and canal fillings with conventional gutta percha were performed after routine biomechanical preparations. The experimental intracoronal base was placed either at the cementoenamel junction(group 3, 4) or 2㎜ below cementoenamel junction(group 1, 2). Walking bleaching was performed by two different combinations of bleaching agents ; sodium perborate with distilled water in group 1, 3 and sodium perbrate with Superoxol in group 2, 4. The roots of the teeth were evaluated for the presence of color change to assess the leakage of bleaching agents and the cervical one-thirds of the crowns were evaluated for bleaching effect from the Whiteness Index calculated by spectrophotometer. The results were as follows 1. At the end of 12 days, all the sample teeth demonstrated the increase of Whiteness Index at cervical 1/3 of crown although there were some minor differences among groups. 2. Regardless of location of the base, sodium perborate with superoxol(group 2, 4) showed better results in bleaching than the sodium perborate with distilled water(group 1, 3). 3. Bleaching agent leaked into the root area when the base was placed 2㎜ below cementoenamel junction but no leakage was found when the base was placed at the cementoenamel junction.

One of the recent procedures, the slip line field theory is adopted to find out the exact blank profile for deep drawing square and rectangular cups with a uniform height. The uniformity of drawn cup heights with ideal blanks by this theory is compared with that from other blanks. Drawing forces and thickness distributions are also described experimentally. From this approach, the use of ideal blanks could be suggested to obtain the deeper and the better square and rectangular cups with uniform heights which reduce the trimming allowance to a minimum.

서비스디자인과 Innovative 광고의 사례 비교 연구

신재현,박승배 한국정보디자인학회 2013 정보디자인학연구 Vol.16 No.2

최근 디지털 기술의 발전과 소셜 네트워크의 개발로 인해 미디어 환경이 변화하면서 소비자가 정보의 발신자가 아닌 수신자가 주도권을 잡는 시대로 변화하였다. 또한 최근 Cannes Lions 광고제에서 보여주듯이 새로운 형태의 광고들이 계속적으로 등장하고 있다. 하지만 국내 광고대행사들의 광고개발에 대한 환경은 변화되지 않고 있다. 이에 따라 새로운 방법론과 환경에 대한 연구로 새로운 미디어의 광고 제작환경을 만들어 나아갈 시점이다. 본 연구에서는 2013년도 광고의 현황파악과 소비자의 공감과 참여가 중요한 역할을 하는 광고시장 변화에 대응할 수 있는 광고 제작 방법론의 개발을 위한 대안으로 결과물에서 유사성을 보이고 있는 서비스디자인과 Innovative 광고사례를 Ducoffe, R. H.(1996)의 광고 속성요인 이론을 차용하여 분석하였다. 분석된 내용을 바탕으로 앞으로의 Innovative 광고개발을 위한 발전방향에 대해 연구해 보았다.

3,5,5-trimethylhexanoic acid(THA)와 트리메틸올프로판올 에스테르화시켜 중간생성물을 얻은 후, 중간생성물 속의 알키드 폴리올 성분인 THA의 함량을 10, 20, 30wt%로 변화시키면서 1,4-부탄디올, 트리메틸올프로판 및 아디프산과 축중합하여 알키드 변성폴리에스테르를 각각 합성하였다. 위에서 합성된 알키드 변성폴리에스테르에 폴리이소시아네이트쪽 성분인 Desmodur L-75와 블렌드하여 2성분계 폴리우레탄 도료를 제조하였다. 제조된 도료의 도막처리후의 제반 물성시험을 해 본 결과 3,5,5-trimethylhexanoic acid의 함량증가에 따라 8^-점의 높은 연화도, 2-3시간의 짧은 건조시간 및 18∼23시간의 긴 가사시간을 나타내어 알키드기의 장점이 일부 나타남을 확인하였다. Alkyd modified polyester was synthesized by the polycondensation of 1,4-butanediol, trimethylolpropane, adipic acid, and the intermediate obtained by the esterification of 3,5,5-trimethylhexanoic acid(THA) and trimethylolpropane, where the contents of THA as a component of alkyd polyol in the intermediate were changed according to 10, 20, and 30wt%, respectively. Two-component polyurethane coatings were prepared by blending the synthesized alkyd modified polyester with Desmodur L-75 as a component of polyisocyanate. Various tests for coating properties with the prepared coatings show that high fineness of grind of 8^-point, short drying time of 2∼3 hours, and long pot-life of 18-23 hours were observed with the content of 3,5,5-trimethylhexanoic acid.

Validity and Classification Accuracy of CBM Oral Reading and Maze to Identify Students at Risk for Reading Disabilities: A Review of Literature

신재현 이화여자대학교 특수교육연구소 2017 특수교육 Vol.16 No.4

Purpose: The purpose of this study was to systematically synthesize the validity(concurrent and predictive) and classification accuracy(sensitivity and specificity) of CBM oral reading and maze task as screening tools for identifying students at-risk for reading disabilities in Grades 1-6. Specifically, this study focused on the classification accuracy of oral reading and maze to evaluate evidence for the two CBM measures as screening tools. Method: Twenty-three studies conducted in Grades 1-6 were systematically reviewed. Results: For oral reading, correlations appeared to vary in magnitude(r=.43-.75) across grades. Correlations for maze ranged from r=.49-.73 across Grades 3-5. In terms of classification accuracy, oral reading tended to show relatively lower level of sensitivity than specificity in Grades 1-3. However, this difference was not observed in intermediate grades. No classification accuracy results were reported for maze. Conclusion: Based on these findings, the evidence base of CBM oral reading and maze as screening tools was evaluated to identify students at-risk for reading comprehension difficulties. Implications for research and practice are discussed.

쓰기학습장애 위험군 선별을 위한 교육과정중심측정(CBM) 쓰기검사의 타당도: 메타분석을 중심으로

신재현 한국학습장애학회 2019 학습장애연구 Vol.16 No.1

The purpose of this study was to investigate the validity of CBM Writing (CBM-W) for identifying students at risk for or having writing disabilities. This study synthesized 19 studies that presented the relations between CBM-W and standardized writing achievement tests, and conducted a random-effects meta-analysis to analyze true mean effect size and its variance. In addition, several moderator variables were used to account for variance in the effect size. The mean correlation was moderate (r=.46). Moderator analyses revealed that grade range and scoring procedure made statistically significant differences in the mean correlations. Based on these results, the usability of CBM-W in practice and implications for future research were discussed. 본 연구의 목적은 쓰기학습장애 위험군 선별을 위한 교육과정중심측정 쓰기검사(CBM Writing)의 측정학적 적합성 중 준거타당도를 메타분석을 통해 종합적으로 살펴보는 것이었다. 연구방법: 이를 위해 CBM 쓰기검사와 표준화 쓰기성취도검사와의 상관관계를 분석한 총 19편의 국내․외 연구들을 체계적으로 종합하였고, 효과크기의 통계적 분석을 위해 무선효과 메타분석(random-effects meta-analysis)을 사용하였다. 또한, 상관관계에 영향을 미치는 조절변인(moderator)들의 영향을 학년수준, CBM 쓰기검사의 종류, 채점방식을 중심으로 살펴보았다. 분석결과 평균 상관관계는 r= .46으로 보통 수준이었고, 조절변인에 따른 분석결과 학년수준 및 CBM 채점방식에서 상관관계의 유의한 차이가 발견되었다. CBM 검사종류에 따라서는 상관관계의 차이가 나타나지 않았다. 이러한 연구결과를 토대로 CBM 쓰기검사의 쓰기 학습장애 선별을 위한 현장 적용 가능성 및 후속연구를 위한 제언이 논의되었다.
