  • In this study, the beeswax extraction methods using organic solvents were examined to develop a optimal dewaxing technology for beeswax-treated Hanji. Thermally-aged beeswax-treated Hanji was dewaxed using four types of extraction methods including dipping, Soxhlet extraction, ultrasonic washing and shaking methods. Then, the aging stability of the dewaxed Hanji was evaluated in terms of variations in paper strength and in the color of the printed area with muk. The experimental results suggested that the dewaxing methods allowing solvent to flow during extraction showed superior extraction efficiency. The dipping method in which the organic solvent does not flow showed the slowest extraction rate of beeswax compared to three other methods. In terms of variations in tensile strength and folding endurance, however, no obvious differences in the aging stability were observed amongst these four extraction methods. Regarding the aging stability in terms of the color of the printed area with muk, Soxhlet extraction method showed the best performance of dewaxing.

  • Fillers have been used to improve the optical and printing properties and to reduce the production cost while increasing the filler content in paper causes adverse effects on paper strength. In the previous study, it was shown that the thick stock addition of filler can increase the filler content without significantly sacrificing paper strength. This study was carried out to elucidate the effect of the location of starch addition (before or after the filler addition) on handsheet properties and a papermaking process as a part of developing the thick stock loading technology. In addition, effects of dual flow addition of cationic starch were evaluated. It was found that paper strength was superior when cationic starch was added after the filler addition. No adverse effects on optical properties, formation and filler retention were observed. Drainage was a bit slower when starch was added after the filler addition, which shall be resolved with regulating other factors. Dual flow addition of cationic starch before and after filler addition did not show any special advantage.

  • Fillers have been used for printing paper to improve printability, sheet formation and optical properties and to reduce production costs by replacing expensive wood pulps. However, an increased filler content will decrease paper strength because filler particles interfere with fiber-fiber bonding. In order to increase filler content without sacrificing too much paper strength in high filler content papers, the surface of precipitated calcium carbonate (PCC) has been modified by adsorbing anionic polyacrylamide and cationic starch in series. The adsorbed polymer layers would enhance interactions between the filler surface and the fiber surface, improving internal bonding. It was found that the modified PCC increased paper strength at a given filler content compared to the coventional method. Negligible differences in optical properties and formation of paper, filler and fines retention and drainage on the wire section were observed between the modified and the conventional PCC. However, the decreased bulk of paper was observed when the modified PCC was used.

  • Factors influencing penetration of PVAm solution into paper during impregnation were investigated with ultrasonic Penetration Evenness Analyzer (PEA). Paper structure was varied by changing basis weight, freeness of pulp, calendering, and filler addition, and hydrophobicity of paper was varied by adding AKD. In addition, the viscosity of PVAm solution was varied by changing the concentration of PVAm solution. Important factors influencing penetration of PVAm solution into paper were found to be the pore structure and the hydrophobicity of paper, and the viscosity of PVAm solution. Pore structure of paper could be controlled by refining degree and filler addition and hydrophobicity of paper could be controlled by internal sizing. Denser structure of paper, higher hydrophobicity and higher liquid viscosity slowed down the penetration of PVAm solution into paper.

  • The optimum dewaxing ratio in dewaxing treatment by the heat and pressure method was investigated by considering aging stability of dewaxed Hanji. Commercial Hanji was coated with beeswax and thermally aged at $150^{\circ}C$ for 24 hours. Then it was dewaxed using the laboratory sheet press equipped with hot plates on both top and bottom sides. Dewaxing ratio was controlled by pressing temperature and time. Four type of dewaxed Hanji samples with different dewaxing ratio were prepared and thermally aged at $150^{\circ}C$. Then the aging stability of dewaxed Hanji samples was evaluated in terms of optical and strength properties. It was found that the aging stability of dewaxed Hanji was superior with higher dewaxing ratio. The result concluded that, in the aspect of aging stability, the coated beeswax in beeswax-treated Hanji shall be completely removed if the coated wax would be dewaxed.

  • Demands of thermal recording paper have been increased significantly by increase in usage of invoice, fax, and label. Thermal recording paper was mainly made based on virgin fiber. It is necessary to find a suitable alternative to virgin fiber in terms of environment protectional resources conservation. In this paper, deinking properties of different recovered papers were analyzed in order to use the recovered paper as raw material of thermal recording paper. Recovered paper were ONP, OMG and white ledger. Flotation reject of OMG was high because inorganic pigments in coating layer could be removed by upstream of froth. Brightness of white ledger and OMG were much higher than that of ONP. Therefore, properties of pulp made from the recovered paper could be enhanced with increase in blending ratio of white ledger and OMG. However, blending ratio of OMG caused the increase of flotation reject. Consequently, the optimum blending ratio of ONP, OMG, and white ledger was 3:3:3 for eco-friendly thermal recording paper. Under the condition, brightness was about 70% and ERIC was below 300 ppm.

  • Recovered paper has been widely used as a main raw material of papermaking in Korea. Recycling of recovered paper helps to reduce production cost and preserve an environment. To recycle recovered paper efficiently, de-inking is a key process in recycling mills. De-inking process would be affected by various influencing factors such as the type of de-inking agent, mixed ratio of recovered paper, season, and process conditions. In this study, fatty acid and nonionic surfactant were used as the de-inking agent in froth-flotation process of mixed recovered paper. De-inking properties of mixed recovered paper were investigated according to the addition level of each chemical. Nonionic surfactant had a small effect on de-inking efficiency of mixed recovered paper due to decreased reject. As the additional level of fatty acid increases, fragmented ink particles increased and then optical properties of recycled paper decreased because fragmented ink particles adsorbed onto the fiber surface.

  • Background and purpose: Gin Ga Chu Yo(該家樞要) was written in the year 1359 by Hwal Su(滑壽) who was a famous oriental doctor between Won(元) and Myeong(明) dynasty. As specialized in sphygmology(脈學), this book was brought together most things about sphygmology(脈學) before Won(元) dynasty by the author. Moreover he added the self-realized things to this book. Methods: In this book, there are all 20 chapters; Chu Yo Hyeon Eon(樞要玄言), Jwa U Su Bae Jang Bu Bu Wi (左右手配臟腑部立), O Jang(五臟), Sa Si peong Maek(四時平脈), Nae Gyeong Sam Bu Maek Beop(內經三部脈法), Ho Heup Chim Bu Jeong O Jang Beop(呼吸沈浮定五臟法), In Ji Ha Gyeong Jung I Jeong O Jang Beop(因指下輕重以定五臟法), Sam Bu So Ju(三部所主), Ji Maek Su Beop(持脈手法), Maek Gwi Yu Sin(脈實有神), Maek Eum Yang Yu Seong(脈陰陽類成 ), Gyeom Hyeon Maek Ryu(兼見脈類), Je Maek Ui Gi Ryu(諸脈宜忌類), Heom Je Sa Jeung Ryu(驗諸死症類) , Sa Jeol Maek Ryu(死絶脈類), O Jang Dong Ji Maek(五藏動止脈), Bu In Maek Beop(婦人脈法), So A Maek Beop(小兒脈法), Maek Sang Tong Hoe(脈象統會), Maek Sang Ga(脈象歌) and an epilogue in the end. This treatise is made up of principal, notes, study and conclusion, we tried to make a translation faithful to the original. Results and Conclusion: Looking into this book, we can know that it is very detail in analyzing item by item, bright and simple in explaining and it is very useful in studying pulse evaluation(脈診). In his preface, Hwal Su(滑壽) expresses his opinion with firm confidence that 'Do(道) of the World scattered in several scholarships and books of method and technique(方術). Nothing of method and technique(方術 ) is more important than medicine. Nothing of medicine goes before pulse evaluation(脈診).' With such good reasons, as a student of sphygmology(脈學), I think this book is very valuable in studying pulse evaluation. So I add Hangul suffixes(吐) to a part of this book and translate it into Korean.
