This study was conducted to discuss concrete ways to contribute to the sustainability of the planet by actively applying and using digital and IT resources in libraries. To this end, a survey was conducted for librarians of public libraries, and the results were as follows. First, librarians' awareness of the seriousness of environmental problems and the degree of eco-friendly activities were very high, but their awareness of library green IT and familiarity with eco-related terms were very low. Nevertheless, there was a high degree of agreement on the importance of applying green IT to libraries. Second, the areas evaluated as having the highest contribution to eco-friendliness and greening of the library were found in the equipment and product operation area, followed by the service area and the network and system area. Third, how do you think library green IT will have a social impact? The highest opinion was given that it could increase the awareness of the library's social responsibility as a social infrastructure. In conclusion, it seems that the library's green IT can contribute to improving library perception by making the public perceived as an institution that has a social responsibility as a social infrastructure.

세계의 모든 나라가 화석연료를 대체하는 태양광, 풍력 등의 그린에너지 기술개발에 주력하고 있으며, 한편으로는 에너지의 효율제고 및 재생을 위하여 폐기물로부터의 자원순환을 이룩하는 폐기에너지 회수에도 많은 노력을 기울이고 있다. 그 하나의 방편이 버려지는 쓰레기에서 에너지를 회수하는 고형재생연료인 RDF(생활폐기물 고형연료 제품, Refuse Derived Fuel) 생산이다. 우리나라에서는 유일하게 강원도 원주시에서 하루 80톤을 생산하고 있으며 아직은 기술도입 초기단계에 있는 가연성폐기물의 연료화 기술이다. RDF의 특성은 불연성 성분이 제거된 일반 가연물을 분쇄하여 압출성형 가공한 펠릿형상의 고체연료로서의 열적 특성이 우수하나 화재안전 측면에서는 제조 및 취급공정에서의 일반적인 가연물 화재위험성을 가지고 있고, 저장과정에서는 축열발열에 의한 자연발화 위험성이 상존하며, 저장형태, 특히 사이로의 경우 구조특성으로 인하여 화재진압도 쉽지않다. 본 논문에서는 일본의 RDF 화재사례를 중심으로 그 화재 위험 특성과 안전대책을 고찰하고자 한다.

풍력산업은 발전사업과 풍력터빈 제조산업으로 나뉜다. 세계의 풍력터빈의 설치량은 1996년을 기준으로 해서 매년 평균 28.6%의 성장률을 보여왔다[1]. 2008년 이후 그 성장세가 다소 꺾이기는 했지만, 그린에너지에 대한 세계적인 관심과 욕구, 화석연료 의존에서의 탈피 등의 이유로 계속적인 성장이 예상되고 있다. 특히 재생에너지 분야에서는 가장 시장 경쟁력을 확보할 수 있기 때문에 예측의 실현 가능성이 높다 하겠다. 풍력터빈과 그 부품 산업 역시 유럽이 주도적으로 끌고 나가고 있으며, 아시아와 북미의 시장이 대두됨에 따라서 지역의 풍력산업이 활발하게 발전하고 있다. 국내는 발전사업보다는 제조산업에 1차적인 관심이 있으며, 이를 바탕으로 국산화 모델의 개발 및 상용화에 정부와 민간이 힘을 쏟고 있다. 제품의 개발과 상용화는 시장을 바탕으로 이루어지는데, 불행하게도 국내의 풍력발전 시장은 매우 좁아서 국내 풍력터빈 제조사의 성장에 어려운 점이 있다. 하지만, 국내의 중공업기반과 산업수준을 적극 활용하여 터빈 완제품 및 부품산업의 발전을 위하여 국가와 민간차원에서의 노력이 가중되고 있다.

This study investigated the purchase intention of green fashion products based on Rogers' Diffusion of Innovation theory and compared the differences between Korean and British consumers. In order to identify the impact of personal characteristics, this study also examined the effects of fashion innovativeness and LOHAS tendency on perceived attributes of innovation and intention to purchase. With a convenience sampling method, a survey questionnaire was distributed at popular fashion streets in each country. A total of 426 data were obtained, 203 from the UK and 223 from Korea. About 52% were females, and 69% were in their twenties. A factor analysis generated two LOHAS factors (health concerns and eco concerns) and four attributes of green fashion products (image improvement, symbolic superiority, observability, and compatibility). Two types of green fashion products (organic cotton t-shirts and organic cotton t-shirts with an environmental message) were provided to measure the purchase intention, respectively. The findings were as follows. British consumers were more likely to show LOHAS tendency and to perceive positive advantages of green products compared to Koreans; in addition, British consumers presented higher mean scores on the purchase intentions of organic cotton products. Fashion innovativeness was significant to predict image improvement and symbolic superiority, while eco concerns were significant in compatibility for both nations. Compatibility was important for both countries in order to explain the intention to adopt two types of organic products. In addition, image improvement was another predictor for purchase intention of organic t-shirts with an environmental message. Managerial implications were provided.

Purpose This study aims to understand the role of digital knowledge in accepting the green technology. This study combined digital option theory with the second version of the Unified Theory of Acceptance and Use of Technology (UTAUT2). Contrary to other studies in which the UTAUT2 is used to explain IT adoption behavior, we look at the relationship between IT and the UTAUT2 from a new angle, incorporating an important aspect of IT, that is, digitized knowledge richness, as a determinant of the UTAUT2. Design/methodology/approach Grounded in the UTAUT2, a content analysis was conducted to investigate novel constructs dedicated to explaining green technology adoption. In this study, an amended version of the UTAUT2 specific to green technology is offered that better explains the green technology adoption behavior of consumers. Using the items identified by content analysis, we developed a questionnaire with 36 survey items. We measured all the items on a seven-point Likert-type scale. We randomly selected 402 survey respondents from a set of panel data. After a pilot study, we analyzed the main survey data by using PLS 2.0M3 and SPSS 20.0, and employed structural equation modeling to test the hypotheses. Findings The results suggest that the UTAUT2 was found to be extendable to technologies other than conventional IT. Social influence is more significant than conventional utilitarian and hedonic-based constructs such as those utilized in the UTAUT and UTAUT2 in explaining adoption behavior in the context of green technologies. The hypothesized connection between digitized knowledge richness and adoption intention was supported by the results of studies on the role of IT in formation of attitudes toward eco-friendly production. The results also indicate that digital knowledge can also encourage people to try green technology when they learn that their peers are already using the technology successfully.

With the development of the bio industry, membrane chromatography with a high adsorption efficiency is emerging to replace the existing column chromatography used in the downstream processes of pharmaceuticals, food, etc. In this study, through the deacetylation reaction of two commercial cellulose acetate (CA) membranes with different pore sizes, the porous regenerated cellulose (RC) supports for membrane chromatography were obtained to attach the anion exchange ligands. The adsorptive membranes for anion exchange were prepared by attaching an anion exchange ligand ([3-(methacryloylamino) propyl] trimethylammonium chloride) containing quaternary ammonium groups on the RC supports by grafting and UV polymerization. The protein adsorption capacities of the prepared membranes were obtained through both the static binding capacity (SBC) and the dynamic adsorption capacity (DBC) measurement. As a result, the membrane chromatography with the smaller the pore size, the larger the surface area showed the highest protein adsorption capacity. Membrane chromatography which was prepared by using deacetylated commercial CA support with MAPTAC ligand (i.e., RC 0.8 + MAPTAC: 43.69 mg/ml, RC 3.0 + MAPTAC: 36.33 mg/ml) showed a higher adsorption capacity compared to commercial membrane chromatography (28.38 mg/ml).

Alkaline water electrolysis system is the oldest technology among various hydrogen production processes to produce green hydrogen with the least amount of greenhouse gas generated. Alkaline water electrolysis (AWE) system is used in alkaline atmosphere condition. In comparison to polymer electrolyte membrane water electrolysis (PEMWE), this system can utilize stable transition metals such as nickel, cobalt, and silver, as electrode catalysts. AWE is relatively inexpensive, and can easily be scaled up to large scale. The system is a mature technology, as it has been in operation since the beginning of the 20th century in MW-scale for hydrogen generation, and there are currently more than 20 commercial manufacturers. In this review, the basic principles of AWE, along with catalysts, electrodes, and diaphragm membranes, are summarized. Particularly, the research and development trends of the diaphragm membrane unit, which is the core component of an AWE, are discussed in detail.

To evaluate the effectiveness of the skin barrier improvement of lactic acid (LA) and gluconolactone (GL), the expression of filaggrin, loricrin, hyaluronic acid (HA), hyaluronan syhthase-2 (HAS2), and aquaporine-3 (AQP3) in keratinocytes, and the moisture content and transepidermal water loss (TEWL) by clinical trials were evaluated. The expression levels of filaggrin and locricrin, which are the main factors affecting the proper functioning of skin barrier function, and HA, HAS2, and AQP3, which are skin moisturizing-related proteins measured by quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting. The results showed that the expression levels of the factors that decreased by H2O2 treatment were significantly increased by LA, GL, and a mixture of LA and GL at the mRNA and protein levels (p<0.05). The nanoemulsion containing a mixture of LA and GL was prepared using the emulsion inversion method, and the average particle size was 299.9 ± 0.287 nm. After measuring the TEWL of nanoemulsion using Vapometer, it was found that TEWL significantly decreased by 15.53% and 26.73% after two weeks and four weeks of product use, respectively, compared to TEWL before product use (p<0.001). Similarly, the skin moisture content of the nanoemulsion significantly increased by 15.40% and 26.59% after two weeks and four weeks of product use, respectively, compared to skin moisture content before product use (p<0.001). Therefore, the skin barrier function and moisturizing effect of a mixture of LA and GL are shown by increasing the moisture content and decreasing the TEWL by increasing the expression of filaggrin, loricrin, HA, HAS2, and AQP3. This suggests the possibility for the development of functional cosmetic ingredients in the future.
