To improve the physical properties of protein films, various plasticizers and cross-linking agents were used in the preparation of the films. For zein film, 3% polypropylene glycol with 3% glycerol was the best plasticizer, while 2.5% glycerol was the most suitable for soy protein isolate (SPI) film in terms of tensile strength (TS), % elongation, and water vapor permeability (WVP). Formaldehyde, glutaraldehyde, glyoxal, and cinnamaldehyde as cross-linking agents of protein films were used to further improve the physical properties of the films. All aldehydes used as cross-linking agent in this study improved TS of zein and SPI films. In particular, cinnamaldehyde was the best cross-linking agent due to its safety in foods. These results suggest that appropriate use of plasticizer and cross-linking agent like cinnamaldehyde should improve the physical properties of protein films for use in food packaging.

This study seeks to present an option for including a variety of information resources in a reference linking service system. Discussion on reference linking service in journals began in 1999 and applied to real systems, but linking to research papers and patent registers has more recently emerged. This study further suggests that system construction include various information resources such as books and dissertations. This paper also presents principles and prerequisites that should be considered essential when building such systems, including expansion of resources and media formats, development of identifiers on every sort of information resource, linking methods to existing DB, publication revolution and managing copyright-holders, use and improvement of OPACs, and building perfect authority DB.

KISTI는 CrossRef/DOI 기탁사업을 통해 학술정보생산자인 학회나 기관에게 해외유통망을 지원하는 사업을 해오고 있다. 그리고 DOI 기반의 학술논문간 인용정보 서비스인 Cited-by linking 결과를 과학 기술학회마을을 통해 논문의 인용횟수와 인용논문정보를 제공하고 있다. CrossRef에서 회원에게만 제공하는 Cited-by linking 결과를 분석해보면, KISTI에서 기탁하는 논문수가 증가함에 따라 인용논문수도 지속적으로 증가하고 있는 것을 볼 수 있다[1]. 이에 따라 Cited-by linking 결과를 학회나 기관이 쉽게 접근 할 수 있도록 KISTI 학술정보통합관리시스템에 적용하는 방안을 모색하고자 한다. 학회나 기관이 Cited-by linking결과에 쉽게 접근하여 각 학술지의 인용현황을 관리하고 그 결과 데이터를 활용하여 기존에 서비스되고 있는 정보 외에 필요한 정보를 획득할 수 있도록 지원하는 시스템이다.

Polyalkylsiloxane has been spotlighted in pressure-sensitive adhesive (PSA) application due to excellent physical properties and good biocompatibility. Thermal behaviour of polyalkylsiloxane mixtures, such as thermal stability and heat flow, were studied using TG-DTA during catalytic hydrosilation. To understand reaction kinetics of cross-linking, catalytic hydrosilation of polyalkylsiloxane was monitored using variable temperature nuclear magnetic resonance (VT-NMR) as increased temperature. The formation of cross-linking bond $Si-CH_2-CH_2-Si$ was directly observed using distortionless enhanced by polarization transfer (DEPT) technique. Successfully polyalkylsiloxane PSA samples exhibited excellent adhesion properties by cross-linking reaction.

Citing literature is a very important activity for scholars in writing articles. Many publishers and libraries build citation databases and provide citation reports on scholarly journals. Cited-by linking is a service representing what an article cites and how many times it cites a specific article within a journal database. Recently, information services based on DOIs (Digital Object Identifiers) have been increasing in number. CrossRef, a non-profit organization for the DOI registration agency, maintains the DOI system and provides the cited-by linking service. Recently, the number of Korean journals adopting DOI is also rapidly increasing. The Korea Institute of Science and Technology Information (KISTI) supports Korean learned societies in DOI related activities in collaboration with CrossRef. This study analyzes cited patterns of Korean DOI journal articles using CrossRef's cited-by linking data and a Korean journal citation database. This analysis has been performed in terms of publication country and the language of journals citing Korean journal articles. The results show that DOI, SCI(E) (Science Citation Index (Expanded)), and English journals are more likely to be cited internationally.

In this study, carbonized fibers were prepared by using acidically cross-linked LDPE fibers. The surface morphologies of the carbonized fibers were observed by SEM. The effects of cross-linking process temperatures were studied using thermal analyses such as DSC and TGA. The melting and heating enthalpy of the fibers decreased as the cross-linking temperature increased. The cross-linked fibers had a carbonization yield of over 50%. From SEM results the highest yield of carbonized LDPE-based fibers was obtained by cross-linking at a sulfate temperature ($170^{\circ}C$). As a result, carbonation yield of the carbonized fibers was found to depend on the functions of the cross-linking ratio of the LDPE precursors.

옥수수 전분을 하이드록시프로필화 및 가교화시켜 변성 전분을 제조한 후 DSC, Amylograph 등을 이용하여 호화특성을 연구하고 호화액의 gel 특성을 조사하였다. 하이드록시프로필화에 의하여 옥수수 전분의 호화온도는 크게 떨어졌으며 가교화만을 시킨 전분은 호화온도가 약간 상승하였으며 호화엔탈피는 약간 감소하였다. 하이드록시프로필화와 가교화를 동시에 시켰을 때는 호화온도가 크게 떨어져 하이드록시프로필화만 시킨 것보다는 약간 높았으나 팽윤이 억제되었고 gel 조직강도는 증가하였다.

Blood glue was prepared to reutilize porcine blood. Plasma proteins after lyophilization were treated by addition of wood flour, sodium hydroxide, sodium silicate, and hydrated lime to make blood glue with a suitable adhesivity. Characteristics of the prepared blood glue was monitored by measuring the viscosity with time, and the relationship between degree of hydrolysis of plasma proteins by addition of various amounts of sodium hydroxide and adhesivity was studied. To prevent the emission of formaldehyde during manufacturing of plywood by blood glue, the cross-linking reaction of plasma protein with formaldehyde was also examined. Fourier transform infrared, circular dichroism, and fluorescence spectroscopy study showed that blood plasma proteins react with formaldehyde, resulting in removal of formaldehyde by cross-linking reaction.
