  • Cellulose fibers is one of the most abundant in nature. It has many distinctive features: abundant in nature, biodegradable, non-toxic, eco-friendly, sustainable, easy to fabricate, hydrophilic, and cost-effective. Cellulose fibers, known as pulp, is produced from cellulose-containing materials by the pulping process. As the raw material, wood has been most commonly used while recycled pulp has been also used to some degree. Thus, pulp usually refers to wood pulp. Generally, the pulp and paper industry is regarded as the commodity market where the cost should be much more important than the quality. It also belongs to a mature market where the growth is slow, or even in decline. Accordingly, technological development has been rather stagnant for the industry. Recently, however, the pulp and paper industry has faced very serious challenges. First, due to digital technology, there has been a steady decline in the need for pulp and paper products. The digital industry has continuously replaced printed products such as books, newspapers, and magazines. Second, there has been a trend initiated by developed countries to limit the use of wood as the raw material for the sake of environmental protection. This forces the industry to find a more efficient use of wood pulp as well as finding alternative, non-wood sources. Third, as an individual becomes wealthier and more conscious of health-care, the quality of a product becomes more important than the cost. Thus, a paradigm shift is needed from the cost-conscientious to the quality conscientious. The objective of this article is to review the technologies aimed at engineering cellulose fibers for producing high-value added paper products.

  • 본 연구는 한국산업표준(KS)의 전문성을 강화하기 위한 범부처 참여형 표준운영 정책이 실시됨에 따라 목재 및 펄프 제지 산업표준과 관련하여 산업표준화법에 따른 표준운영 현황을 파악하고, 단계적인 표준 정비방안과 표준 활성화 방안을 제시하는 것을 목적으로 하였다. 산림청은 2015년에 목재 및 펄프 제지산업분야 KS를 산업통상자원부로부터 이관 받아 현재는 426종의 관련 표준을 관리 운영하고 있으며 3개 분야 전문위원회(목재 목조건축분야, 목질재료분야, 펄프 제지분야)와 목재 제지 기술심의회를 신설하여 표준의 제 개정 안건을 심의 하도록 하였다. 목재 및 제지 산업분야의 국가표준이 전문 부처에서 관리되는 만큼 기술 경쟁력 향상과 시장성을 확보하는데 기여할 수 있도록 기존 표준의 재정비와 실용적인 표준 개발이 필요한 시점이다. 이를 위해서 표준 운영에 대한 체계 수립과 전략적인 표준 분석이 필요하다. 더 나아가 KS와 국제 표준과의 부합화를 통해 국제 무역에서 표준의 상이성에 따른 기술 장벽이 되지 않도록 하며, 지속적인 정책적 지원과 표준개발 역량을 강화하기 위한 전문 인력의 육성이 뒷받침 되어야 할 것이다.

  • 이 연구의 목적은 임업과 목재산업이 전체 경제에 미치는 영향 그리고 산업의 연관관계를 분석하는 데 있다. 이를 위해 한국은행의 2015년 산업연관표를 이용하여 임업과 목재산업 중심으로 재분류하고 경제적 파급효과와 다른 산업에 미치는 영향을 분석하였다. 생산유발효과는 종이제품 생산업, 제재업, 영림업에서 상대적으로 높게 나타났고, 다른 목재산업의 생산유발효과는 크지 않았다. 부가가치유발효과는 영림과 원목생산에서 높게 나타났다. 그리고 목재산업에서 후방연쇄효과보다 전방연쇄효과가 높게 나타나 경제 전체를 유지하는 데 중요한 것으로 나타났다. 다른 산업에 미치는 파급효과를 분석한 결과를 보면 목재산업의 생산증가가 임업에 미치는 파급효과가 크지 않은 것으로 나타났다. 목재산업과 임업은 산림생태계관리와 기후변화 대응에서 중요한 역할을 하므로 이들의 연관성을 높이는 것은 산림정책에서 중요한 정책과제이다.

  • The energy efficiency of papermaking process becomes more significant because of various new regulation of the energy consumption and the green house gas emission. In this study, the effects of wood powder addition on the drainage and the drying efficiency of the OCC based paper products, linerboard, were deeply investigated for improving energy efficiency. The fractionation of wood powder depending on the size were conducted. The bigger size of wood powder resulted in the higher bulk and the higher drainage efficiency, but the lower paper strength. The drying efficiency were in detail evaluated depending on the drying process level. In the first section of drying process until the 80% solid level, there were no significant changes in the drying efficiency by the addition of wood powder. However, after the 80 % solid level, the drying efficiency was greatly improved by the addition of wood powder. Those results showed the addition of wood powder could greatly affect not only the drainage in forming and wet pressing but also the drying process.

  • The average injury rate in sawmilling industry for the last 5 years is 4.99%, which means that more than 200 injuries have occurred in that industry every year. Because the first step in risk assessment is the hazard identification, it is very important to know how to define the hazard and nature of harm. We analyzed 643 accident records of three years(2010-2012) and carried out site survey for the same cases. As a result, the most common types of work at the time of injury in sawmilling industry were removing jammed wood 81(12.8%), wood carrying task 52(8.1%), wood cutting 49(7.6%), travelling table log band saw 41(6.4%), maintenance 37(5.8%) etc. In addition, there were statistically significant differences in some analysis factors such as injured body parts, employment size, and handling material among different working places. Therefore, it is concluded that differentiated prevention efforts are necessary in each workplace.
