최근 정부의 글로벌 자유무역협정(FTA) 네트워크의 구축방침에 따라 대부분의 낙농선진국과의 FTA 협상이 동시다발적으로 이루어지고 있다. 그런 가운데 시유무역이 가능하며, 세계 최대시장이라 할 수 있는 중국과의 유제품무역이 지니는 의의는 매우 크다. 이는 한 중 FTA가 타결될 경우 양국 간의 지리적 여건 및 생산비격차를 감안할 때 시유를 포함한 유제품의 쌍방무역의 가능성이 매우 높기 때문이다. 물론 당장은 중국의 공급 부족 및 2008년의 멜라민사건 등으로 인해 국내산 시유를 포함한 국산유제품의 대 중국수출의 가능성이 높다. 그러나 중장기적으로는 멜라민사건 당시 확인된 것과 같이 저가의 중국산 유제품의 수입가능성 또한 배제할 수 없다. 그 경우 국내 소비자의 중국산 유제품의 안전성에 대한 불신에 따른 이른바 '국산프리미엄'이 작용할 수 있다. 그뿐 아니라 멜라민사건을 계기로 중국 정부는 중국산 유제품을 포함한 식품안전성확보를 위한 제도적장치를 강화하고 있다. 이 같은 점을 감안할 때 한 중 FTA에 대비하여 국산유제품의 대 중국 수출과 함께 저가의 중국산 유제품의 수입가능성에 대해서도 대비할 필요가 있다. 본 연구는 상기와 같은 문제의식 하에서 최근 중국의 우유수급, 중국의 낙농정책, FTA 추진상황, 한 중 유제품무역의 실태, 한 중 FTA에 따른 국내 낙농업에의 영향 및 대응방안 등에 대해 검토하는 것을 목적으로 한다.

It was predicted that the most recent technological developments in concrete technology rely on enhanced admixture efficiency rather than on improvement in cement manufacturing. Four major commercially available of organic chemical admixtures are modified lignosulfonates (LS), sulfonated naphthalene-formaldehyde resins (SNF), sulfonated melamine-formaldehyde resins(SMF) and polycarboxylate(PC). In this study, various sulfonated melamine-formaldehyde (SMF) superplasticizers were synthesized via four synthetic steps and reaction conditions such as the mole ratio of melamine to formaldehyde was changed. After application of SMF superplasticizer to cement concrete, the physical properties including workability, slump loss, compressive strength were compared with SNF

2008년은 중국이 최초로 올림픽을 개최하면서 중국의 고도성장을 과시하는 계기가 되었고, 우주 유영을 성공하는 등 중국의 위상을 세계에 알리는 계기가 되었었다. 또한, 멜라민 파동으로 각 국 정부들은 멜라민 함유 식품제거에 혈안이 되었고 분유에 대한 주부들과 식품에 대한 시민들의 불신으로 한동안 큰 이슈로 자리잡았다. 한편 2008년 인도에서는 핵발전을 통해 만성적인 전력 부족에서 탈피하고자 미국과 민간 핵 부문에서 상호 협력을 위한 협정을 조인했다. 그러나 인도에서는 폭력과 방화, 파괴, 폭탄 테러가 난무해 많은 사상자를 내기도 했다. 다음은 포스코경영연구소에서 발표한 '친디아 10대 이슈'를 정리한 것이다.

In order to investigate the effective sericin fixation of raw silk fibers the influence of various additives added to the melamine and formalin mixtures on sericin fixation was studied. When raw silk fibers were treated with wetting agent but without subsequent washing before sericin fixation, the strong sericin fixation was obtained by fixing sericin. Adding hydrogen peroxide to the melamine and formalin mixture made sericin fixation worse, resulting weaken the sericin hardness of fixed raw silk fibers and tight bonding of the fibers. On the other hand, it was confirmed that adding sodium hydrosulfite to the melamine and formalin mixtures gave better sericin hardness of fixed raw silk fibers without the bonding of fibers. Supplying additional melamine with he low concentration of sodium hydroxide to the melamine and formalin mixture(melamine:formalin= 1:6) resulted in very good sericin fixation. But adding hydrochloric acid or methanol to the same mixture had no effect on the sericin fixation, and adding magnesium chloride to it made the hardness of sericin fixation even worse.

To accelerate the curing and to improve the bonding properties of urea-melamine-formaldehyde (UMF) resin adhesives for plywood, the effects of resin compositions and additives on gelation time and bonding strength were discussed. The gelation time of UMF resin prepared by simultaneous reaction with urea(U), melamine(M) and formaldehyde(F) at M/U molar ratio 0.2 was shortened as the molar ratio of formaldehyde to urea was increased. However, at F/U molar ratios higher than 2.5, the amounts of free fomaldehyde of resin could not satisfy with KS standard, Therefore, it was difficult to increase the amount of formaldehyde in resin composition for the purpose of fast gelation time. With increasing the molar ratio of melamine to urea(M/U) from 0.3 to 0.6 at constant F/U molar ratio 3.4, the gelation time of UMF resin was slightly decreased, while gradually increased at M/U molar ratio higher than 0.6. The gelation properties of UMF resin and bonding strength of UMF-bonded plywood could be enhanced by using ammonium chloride and p-toluene sulfonic acid as a curing-agent together with wheat flour and corngluten powder as a extender.

Agricultural straws such as rice and barley were used as partial replacement of raw materials for particleboard (PB) manufacture. A melamine-urea-formaldehyde (MUF) resin, based on 5 percent melamine addition of the resin solids weight, was synthesized in the laboratory for the bonding of PB. PBs were made using two straw particles based on 10, 20, 30, 40% oven dry weight addition with MUF resin. PBs were tested for physical and mechanical properties, and water soak dimensional stability. The results indicated that as rice and barley straws addition level were increased, the properties of IB, MOR and dimensional stabilities such as thickness swell and water absorption were decreased. Overall, the agricultural straws can be used at 15% substitution of raw materials for PB manufacture.

This study was to investigate the adhesion properties of fancy veneer and base panels and formaldehyde emission of wood-based floorings bonded with urea-melamine formaldehyde adhesives. We focused on stoichiometric mole ratio of reactive functional groups. The urea-melamine formaldehyde adhesives were made at twelve different formaldehyde/urea-melamine mole ratios. The interlaminated shear strength and formaldehyde emission of wood-based floorings bonded with selected adhesive among these adhesives were examined. The results showed that the bonding properties were high and the formaldehyde emission was low as the adhesive consisted of stoichiometric mole ratio of formaldehyde/urea-melamine. Interlaminated shear strengths of HDF(High Density Fiberboard) flooring were over 14 kgf/cm² at all mole ratios. At the mole ratio of 1.0, HDF flooring showed low value of formaldehyde emission of 953 mg/L. Interlaminated shear strengths of Plywood flooring were high, 14.02 kgf/cm² at mole ratio of 1.4. At the mole ratio of 1.0, Plywood flooring showed low value of formaldehyde emission of 0.26 mg/L.
