펄프 개질 및 배합비가 고벌크 종이의 접힘 터짐 저항에 미치는 영향
김동섭,성용주 한국펄프·종이공학회 2023 펄프.종이기술 Vol.55 No.1
The demand of packaging paper has been increasing in order to maintain a sustainable environment through the more reliable recycling of the paper packaging. Since better mechanical properties of packaging paper can expand its range of applications, this study aimed to find a way to improve both fold crushing resistance and bulk properties, which are among the most important properties of packaging paper. The study investigated the effects of raw material conditions, such as the type, mixing ratio, and beating degree of pulp fibers, on the properties of high bulk paper. The results showed that the type of wood chips and pulping methods used had a significant impact on mechanical properties and resistance to cracking. Additionally, adding softwood pulp to appropriately beaten hardwood pulp could form a flexible paper structure while maintaining high bulk, thus improving fold crushing resistance. .

고벌크 지류제품의 접힘터짐 저항성 개선을 위한 지료조성연구
김동섭,성용주 한국펄프·종이공학회 2023 펄프.종이기술 Vol.55 No.1
The demand of high bulk paper products for packaging are increasing due to the delivery service spread and the eco-friend packaging trend. There are some propensities of paper products which should be overcome to increase the reliability of paper packaging. The fold crushing resistance could be one of the major properties of the paper packaging products. In this study, the conditions of the stock such as the mixing ratio of raw materials, the beating degrees of pulp fibers and the application of additives were controlled to evaluate the stock conditions on the fold crushing resistance. By adjusting the ratio of pulp fiber blending and the beating treatment, it was demonstrated in the experiment that both the mechanical properties and folding resistance of packaging paper could be enhanced. The addition of the additives such as PCC and cationic starch led to the increase of the folding resistance. Through both independent and comprehensive impact assessments of the stock conditions, it was determined that the ideal stock conditions for enhancing fold resistance properties could be attained. .

아르누보는 미학적이고 독창적인 양식으로 알려져 있지만, 이와 반대로 지나치게 장식적이며, 합리성이 결여되고, 브르주아만을 위한 양식이라는 비평이 있었다. 이렇게 양분된 평가를 지니고 있는 아르누보에 대하여 이 글을 통하여 산업화 시대의 양식으로서의 개혁적인 가치에 대한 평가와 한계를 살펴보고자 한다. 아르누보는‘과거와는 다른 새로운 양식’을 주창하면서 자연을 모티브로 삼은 새로운 디자인을 출현시켰다. 이 양식은 주관적이며 작가주의적 디자인 방식을 추구하였으며, 생활과 환경의 조화를 추구한 토탈디자인의 개념을 등장시켰다. 하지만 지나치게 수공예에 치중하였으며, 값비싼 재료의 사용과 과도한 제작 비용 때문에 브루주아의 양식으로 치부되었다. 그러나 아르테코와 빈 분리파에 지속적으로 영향력을 미치면서 기하적이고 직선적인 장식의 출현을 도왔으며, 효율적인 제작방식인 프리패브리케이션 건축이 등장하는 데에도 선구적 역할을 담당하였다. Art Nouveau is known as aesthetic and creative movement, but some critics said that it was too much decorative and irrational. Between these two divided critiques, this paper attempts to inspect its reformatory values and limits. Art Nouveau made an appearance of a new design motivated by nature, declaring ‘new style different from the past’. It pursued a subjective and auteuristic way of design and presented the concept of total design seeking the harmony of living and environment. However, Art Nouveau depended too much on handcrafting to increase the quality of manufacturing and it was regarded as a bourgeois style due to the use of high price materials and the excessive cost of manufacturing . But it helped the appearance of geometrical and linear decoration of Art Deco and Vienna Secession, continually influencing on them. It also played a role to make the advent of prefabrication in architecture as an efficient manufacturing.

A variety of flat superhydrophilic surfaces have been fabricated for biological and industrial applications. We report here the preparation of a simple and inexpensive non-polar curved superhydrophilic surface. This surface has dual-scale surface roughness, on both micro- and nanoscales. Curved surfaces with a near-zero water contact angle and ‘complete wetting’ are demonstrated. By using a conventional plasma etching process, which creates microscale irregularity on an aluminum surface, followed by an anodization process which further modifies the plasma etched surface by creating nanoscale structures, we generate a surface having irregularities on two-scales. This surface displays a semi-permanent superhydrophilic property (if the surface has no damage by the exterior failure), having a near-zero contact angle with water drops. We further report a simple and inexpensive curved (i.e., non-planar) superhydrophilic structure with a near-zero contact angle. The dualscale character of the surface increases the capillary force effect and reduces the energy barriers of the nanostructures.

반사방지용 코팅은 태양전지에 있어서 아주 중요한 부분중의 하나이다. 태양전지의 표면에서 반사된 빛은 전지의 효율감소와 직결되기 때문에 반사를 줄이기 위한 많은 노력이 진행되어 왔다. 본 논문은 반사방지막의 원리를 소개하고 태양전지에서 반사방지막으로 많이 사용되는 재료의 광학적 성질과 제조방법에 대해서 알아 보았다. Antireflection (AR) coating has proven effective in providing substantial increase in solar cell efficiency. In this paper, we review the principles of antireflection coating, describe materials and methods of deposition used to provide antireflection coatings on solar cells.
