정보산업의 발달로 동영상 콘텐츠들이 폭발적으로 늘고 있다. 동영상 시청과 동시에 학습을 위해 필기를 할 경우에 화면 분할로 인한 시선 분산으로 강의에 집중하기에 한계가 있다. 이러한 한계를 극복하기 위해 투명도 조정, 최상위 고정, 과목과 주차별 분류 등을 활용하여 학습효과를 극대화함으로써 시청중인 동영상 콘텐츠와 같은 속도로 같은 곳을 바라보며 필기가 가능한 투명한 메모 모듈을 구현하였다.

오픈 소스 소프트웨어 콘텐츠 관리 시스템은 드루팔(Drupal)은 백악관을 비롯해 대규모 사이트에 적용되어 사용되고 있으며, 매우 수준 높은 보안성을 유지하고 있다. 그러나 국내에서는 잘 알려지지 않아 적용 사이트가 매우 드문 상황이다. 본 논문에서는 이러한 두루팔의 기여모듈과 코어모듈 등 구조 분석하고, 실제 웹 사이트를 구축해 두루팔의 실효성을 보인다.

This research were aimed at developing starches which have high preservability and high bonding strength from corn starch, modified cationic and oxidized corn starches, as compared to the fermented wheat starch. On the lining that attaching the base paper on the back of the work with paste, the coating weight was determined by the solid contents of the paste rather than the viscosity of paste. Adhesive strength and stiffness were also determined by the solid contents of the paste. Corn starch had lower solid contents, higher viscosity, and higher adhesive strength than other starches. In the iodine stain to the surface of peeled base paper off, paste deeply penetrated into the traditional Hanji than modern Hanji. And oxidized starch paste deeply penetrated into the paper layer than the cationic starch.

Chemical composition, morphological properties and papermaking properties of Sasa quelpaertensis Nakai were investigated in order to use it comprehensively. The lignin contents of stalks and leaves were 18.8% and 15.3% and the holocellulose contents were 63.3% and 48.6% respectively. The contents of ash and the amount of water extract showed the higher value than those of wood or other bamboo species. The average fibers length and width of Sasa quelpaertensis Nakai were 780 ${\mu}m$ and 14.8 ${\mu}m$. The fibers of Sasa quelpaertensis Nakai stalk had thinner width and more slender structure than those of softwood. The handsheet made of Sasa quelpaertensis Nakai alkaline pulp showed higher in tensile strength and bulkier structure than those of handsheet made of soft wood unbleached kraft pulp.

The quantitative analysis of SB latex contents in coating color and coated paper was investigated with FT/Raman spectroscopy. From the measured FT/IR and FT/Ramon spectra, the peaks of coating color were compared with those of each compoents . Calibration curves were obtained by the area of latex peaks and PLS method of QuantIR program. The relation of predicted values in PLS method and actual values in coating mixtures and coating layer was examined. The components of coating layer in coated paper were investigated by EDS , X-mapping and SEM, The contents of latex in z-direction were calculated in the coating layer of unknown coated paper. The latex concentration measurements of Top layer and Pre layer in double coated paper show that each layer has different value. In single coated paper, it is clear that the latex concentration is highest at the surface and decreases with an increase of depth. From those results it is indicated that the latex migrates to the coated surface. The result of this study may be applied to the binder migration study and the quality control in paper mill.

A new technique for fractionating pulp stock into a long fiber portion and fines fraction was developed by KRICT in order to enhance the drainage and strength properties of recycled OCC pulp. In order to investigate the effect of fines contents in stock and stages of flotation on fractionation efficiency, flotations were performed at varied fines contents and flotation stages. Based on the result of multi-stage flotation fractionation it could be said that fines smaller than 15${\mu}{\textrm}{m}$ stabilize flotation froth of OCC. Although the amounts and the fines contents of flotation reject could be increased by multi-stage flotation fractionation of OCC, flotation stages more than 3 times were found to be inefficient in terms of fines concentrating degree. In order to satisfy the both conditions of reducing long fiber loss and of increasing flotation reject, several kinds of fractionating promoters were searched and investigated. And high molecular weight cationic polyacrylamide was chosen as a long fiber flocculating and flotation froth-stabilizing agent.

"Saengsanbibang" is Obsterics technical books published in 1915. After the publishing of first edition, it was published 15 times so I supposed that this book was very popular in that times. And this book is also valuable because Obsterics books written in Korea are uncommon. But there had not been enough detailed study on this book, so I tried to study on the formation of this book. For that, I compared the formation between this book and 4 kinds of typical Obsterics technical books in Qing dynasty, "Taesansimbub", "Taesanbiseo", "Daesaengyoji", and "Dalsaengpyeon". As the result, "Saengsanbibang" refered to "Dalsaengpyeon" for the contents that the reason and prevention of distocia, the basic principle for antenatal care, and the formulae to tonify blood. The contents that the taking methods of Saenhwatang (生化湯) accroding to the diseases, are mainly affected by "Taesanbiseo". Some contents which had been refered in "Taesansimbub", "Daesaengyoji" weren't refered to "Saengsanbibang". So "Saengsanbibang" is valuable because this book easily summarized the medical knowledge for spreading it to ordinary people. I look forward to more specific study for "Saengsanbibang".

This study is not just a meaning of costume but a function of culture and includes addresses the associated emotions. As the interest of youths has increased recently, the importance of traditional costume education has been growing. Therefore, this study aims to analyze the contents of Hanbok in the 2015 revised high school technology and home textbooks using content analysis techniques and text mining techniques. As a result of the study, first, the symbolic meaning and characteristics of Hanbok and the beauty of Hanbok were practiced in daily life, and the value was found through the excellence of Hanbok and the modernization of Hanbok was dealt with Second, most of the illustrations related to traditional costumes were presented in various ways, but there were some regrets due to lack of quantity and quality. Third, the words used to explain traditional costumes were used in the form of culture, excellence, tradition, modernity, harmony, succession, etc. except for the types of clothing. Therefore, the results and discussions derived from this study are expected to help the textbooks to be efficiently selected and used in the field of the front line school along with the correct understanding of traditional culture in the process of selecting traditional culture contents and illustrations.
