  • This study analyzed regular transportation costs between port warehouses and processing plants and between processing plants and central distribution centers and further transportation costs relations according to empty transfer rates in each circulation by examining the distribution routes of imported grain including wheat, barley, corn, and soybean, namely port warehouses, processing plants, and central distribution centers. Based on the results, the study compared and reviewed the logistics transportation costs. The analysis results of the alternative model show that logistics operational costs could be considerably cut down by introducing a flexible vehicle transportation operational method, which is to change the vehicle loading parts for proper substitute transportation after unloading and transport them to other locations such as central distribution centers instead of returning empty, as an alternative to high operational costs deriving from empty vehicle operation in each circulation after unloading items in case of transportation of imported grain and processed items. The results allow for a more realistic approach to general problems with large-scale distribution network operation and provide a theoretical foundation to serve as a guide to establish policies for corporate operation of imported grain logistics systems.

  • This study was conducted to evaluate the nutritional value of locally produced organic agricultural by-products to substitute imported organic feeds for organic ruminant farming. Imported organic feeds (corn grain, soybean meal, soybean seed, oat grain, barley grain, wheat grain, buckwheat, sunflower seed meal) and byproducts (rice bran, grape seed meal, rice straw, soybean hull, soybean curd, rice hull, green kernel rice, and crushed rice grain) were analyzed for chemical composition and NDF, ADF, mineral, and amino acid contents and anti-nutritional factors. Dry matter, NDF and ADF contents in organic feeds were higher than those in conventional feeds. Especially, the 9.65% fat content of organic soybean meal was 6 times higher than the 1.95% fat content of conventional soybean meal. Fat contents of rice bran, grape seed meal, green kernel rice, and crushed rice grain were 25.66, 6.09, 3.57 and 1.59%, respectively. Protein contents of soybean hull and soybean curd were 14.68 and 19.87%, respectively, which are highest among organic by-products. Levels of aflatoxin in all feeds were below the safety level. Therefore, organic rice bran, green kernel rice and crushed rice as energy source, and soybean hull and soybean curd as protein source could partial replace imported feeds for organic ruminant farming.

  • This study has been focused on the evaluation of domestic softwood timbers to replace imported timbers for woodcrafts and furniture-making. Figures on radial and tangential sections were observed with naked eyes. As the result of study on the figures appeared on the wood surface of 6 species of trees, flat grain and edge grain were clearly found from Taxus cuspidata. Juniperus chinensis and Ginkgo biloba had wavy grain figure and pigment figure, and blister figure was found in Pinus densiflora, Larix kaempferi showed pitch streak and irregular figures on its tangential section due to growth abnormalities. Wavy grain figure appeared weakly on near knot of Pinus koraiensis. The characteristic figures shown from each species of trees are expected to be used for crafts, sculptures, furniture, and interior decoration. They are also considered to have great potential to substitute imported timber sufficiently, which are currently used a lot for wood crafts and furniture-making.

  • The grain quality of imported steamed-rice was investigated to improve the competitiveness of domestic .ice (Oryza sativa L.) in low price market. Eight samples of imported steamed-rice were collected during 2004 and 2005, and they were examined in appearances, physicochemical, pasting, cooking qualities and palatability. In the appearance of grain, there were many cracks, which were easily classified, on the surface of steamed-rice. And they had high protein contents, low moisture contents and very low glossiness. We could certain that there was often decolorization process after boiling according to the wide range of whiteness in steamed-rice samples. Amylograms and thermo-grams of the steamed-rice represented that they were at-ready gelatinized. Thus, we could concluded that the steamed-rice absorbed water with meager endothermic reaction and eluted more soluble solid with many breaks of the grain than milled rice during cooking process. From the sensory preference evaluation, the steamed-rice had the lowest scores among milled rice, long stored rice, and broken rice samples on all evaluation items.

  • In this study, newly developed welding consumables for EGW were welded in EH 36 TM steel plates and their welded joints were evaluated in point of mechanical properties and microstructures compared with imported consumables. Newly developed welding consumables were evaluated as good arc stability and slag fluidity, substantially the same with imported products. The tensile strength of all welded joints were sufficient to meet the requirements specified in a ship’s classification(490~640MPa) and all areas of fracture were heat affected zone(HAZ). Charpy absorbed energy values of all EG welded metals were sufficient to meet the requirements of classification(min. 34J) and those of newly developed wires were evaluated to be better than those of imported wires. As a result observing microstructures of single and tandem EG welded metals through optical and scanning electron microscope (OM&SEM), no grain boundary ferrite(PF(G)) were created in a prior austenite grain boundary and a volume fraction of a fine acicular ferrite were observed very high.

  • 10 carbamate pesticides were surveyed in domestic and imported green peas, beans, red beans from March 1999 through December 1999. Samples were collected from Gwangju, Mokpo, Suncheon and Yosoo grain markets. This study was performed by post-column ο-phthalaldehyde and 2-mercaptoethanol prior to HPCL fluorophore detection. Pesticides were found in 14 of 80 samples(17.5%). The kinds of pesticide detected in green peas were methomyl, MTMC, carbaryl, those in sesames were oxamyl, carbofuran, carbaryl, 1-naphthol, MIPC, those in beans were oxamyl, MTMC, carbaryl and those in red beans were MTMC, carbaryl. The range of residues detected in green peas, sesames, beans and red beans were 0.002∼0.025ppm, 0.001∼0.469ppm, 0.005∼0.356ppm and 0.017∼0.125ppm, respectively. The most frequently detected pesticides were MTMC(6 times) and carbaryl(5 times), while aldicarb, PHC and BPMC were no detected in all samples. Detection frequencies of carbamate pesticides in imported crops were higher than those in domestic ones except red beans. Only one result of oxamyl residues determined in imported bean was higher than the proposed maximum residue limits of Codex, which was 0.356ppm.

  • Transportation and storage technologies, which are key drivers for trade, has increased global trade of agricultural products about 165% from 1995 to 2015. Korea imports 76.2% of grain from major food exporters such as USA, Australia, Brazil, and China. The expected long shipping distances from these countries can seriously cause environmental impacts on various environmental categories such as climate change, particulate matter, and acidification. The goal of this study is to assess the environmental implications focused on greenhouse gases (GHGs) and particulate matters (PMs) emissions of imported grains (wheat, corn, and bean) using food miles analysis and life cycle assessment (LCA). The environmental impacts of imported crops are estimated by transportation modes using the national LCI database provided by Korea Environmental Industry & Technology Institute (KEITI). The results of this study are as follows; (1) Imported wheat comes from USA (29%), AUS (27%), and URK (20%), corn is imported from USA (34%), BRA (29%), and URK (16%), and bean comes from BRA (57%), USA (40%), and CHN (2%); (2) the food miles of imported crops (wheat, corn, and bean) are 3.62E+10, 1.30E+11, and $2.20E+10ton{\cdot}km$, respectively; (3) the potential GHGs and PMs of wheat, corn, and bean are 5.02E+08, 1.67E+09, and 2.84E+08 kg $CO_2e$ and 5.89E+05, 1.83E+06, 3.07E+05 kg $PM_{10}e$, respectively. The outputs of this study could provide environmental impacts and carrying distances of imported agricultural products for preparing a plan to reduce environmental impacts.

  • This study evaluated the grain quality of local brand rice from 6 major rice exporting countries which are anticipated to export their rice to Korea. Recently, with the end of the postponement of rice import tariffs in 2014, Korea is in a very easy environment to import foreign rice. Therefore, the quality evaluation of local brand rice in those countries is needed to secure the quality competitiveness of Korean rice, also to protect the rice industry in Korea. We provided total 38 local brand rice from USA(7), China(16), Australia(4), Thailand(3), Vietnam(5) and India(3), and 2 imported brand rice through MMA from USA and China to find out the status of the grain quality for each country. For the quality evaluation, we analyzed the physicochemical properties, milling and palatability-related characteristics. The amylose content on country average ranged from 24.4(India)~16.2%(Thailand). The protein content was 6.66% by overall average, and was higher in order of India(7.86), Australia(6.80), Vietnam(6.61), Thailand(6.59), China(6.28), USA(5.82). In Toyo glossiness value, it ranged from 75.7~45.2, and the figures in USA and China were the highest level. The head rice ratio ranged from 95.2~72.4%, and the figures in Thailand, USA and China were distinctly high. When we analyze the palatability of boiled brand rice with Chucheongbyeo as check variety by expert panelists, several rice brands from USA and China showed equal or better scores in shape, smell, taste, stickiness, texture and overall score, although most rice brands showed a tendency to decrease significantly in the taste characteristics compared with Chucheongbyeo. From the above results, it can be seen that the grain quality of USA and China rice is very competitive when imported into Korea. The results will provide basic information for the quality control of foreign rice which will be imported into Korea in the near future, also for the quality information which could be applied on the development of high-quality Korean rice varieties. Continuous monitoring about the foreign brand rice is advisable to improve the quality competitiveness of Korean rice.

  • In this study, the figure of domestic hardwood was observed using the naked eye and the possibility of substituting imported wood with domestic one in the making woodcraft or furniture was investigated. It was known from the investigation on 8 different hardwoods that there were various figures such as cloud-shaped figure, blister figure, crotch figure, bird's eye figure, etc. in Zelkova serrata wood and the beautiful pigment figure in Diospyros Kaki wood. There were the unusual figures such as wavy grain figure, fiddle back figure, etc. in Cedrela sinensis wood and was clear ray-fleck figure in Quercus variabilis wood. There were also various figures such as wavy grain figure, blister figure, pigment figure, etc. in Sophra japonica, Tilia amurensis, Castanea crenata, Kalopanax septemlobus wood, etc. It is thus that distinguished figures appeared in each kind of wood can be used for craft, sculpture, furniture, and interior material. These kinds of figures can also be used for instrument, toy, stationery, life article material and souvenir, etc. And it can be expected that they will replace the imported wood has been mainly used to make the woodcraft or furniture until now.

  • Three Korean leading wheat varieties and three imported ones were tested to compare the domestic wheat varieties with imported ones for their grain and Sour quality. The domestic varieties were generally inferior to the imported ones in milling characteristics. The milling rate of the Korean varieties was $66{\sim}68%$, while the imported one was 70%. But Jogwang, one of the Korean varieties had relatively high milling rate, 68%. Jogwang had a protein conten of 9.5%, sedimentation value of 30 ㏄ and Pelshenke value of 35 minutes. Jogwang seems likely to have a suitable quality as a soft variety and it showed somewhat better flour quality than white soft wheat, the imported soft wheat on farinogram.
