  • This paper presents a production planning algorithm for minimizing the costs of production and subcontracting in SCM (supply chain management) environment. In our SCM environment, the several local plants that aye dispersed geographically produce parts and products. In this environment, we have to decide the production volumes of both parts and products considering the BOM (bill-of-material) structure to meet the fixed order quantity or forecasted demand quantity. Each plant produces the specified parts of product with finite production capacity. There exist subcontracting decisions relevant to the production capacity of each plant except the core process plant, and when we use the subcontractor's capacities we should be charged for the fixed subcontracting fees. The objective of this study is to solve the production planning problem, which minimizes the total costs of production, inventory, setup, and subcontracting under constraints of production and subcontracting capacity. For this problem, an integrated production planning model based on the multi-level capacitated lot sizing problem was formulated, and efficient decomposition algorithm was proposed. The experimental investigation shows that the proposed heuristic generates quite good solutions at very low computational costs.

  • This paper proposes a quality control method of assembly parts based on parts inspection information. We use the parts inspection information for reduction of defective fraction in assembly and prediction of assembly quality. At first, we build the functional relationship between parts and assembled unit by regression analysis. Secondly, if we use the inspection informations of parts which are estimators of means and variances, we can predict the nonconforming probability of assembled unit and propose the best assembly method. In a case study, we showed the efficency of the proposed method in two part assembly.

  • When the contents of the constituents such as total amino acids, free amino acids, volatile organosulfuric compounds and steroidal saponins among three origins in the aerial-and underground parts of Allium victorialis, it was suggested that the characteristic components regarding to quality evaluation could be differed according to the purpose of utilization. For the utilization of amino acids, underground parts of this plant was shown to be better than aerial part. In addition, Ulung island origin was found to contain the highest amino acids content among the three origins though the difference was small. The amino acids showing remarkably high contents were appeared to be arginine, glutamine and asparagine. In the volatile organosulfuric compounds, the origina of Mt. Odae and Mt. Chiri positioned in inland showed higher contents than Ulung island origin geographically positioned in the ocean. Inland origins were shown to contain higher organosulfurie component contents in aerial parts than in underground parts while those of Ulung island origin were higher in underground parts than aerial parts. Underground parts, regarding to saponin constituents, showed higher contents than aerial parts. Underground parts of Ulung island origin were shown to contain more saponins than those of other two origins and the sequence of the contents was in the order of Ulung island>Mt. Chiri>Mt Odac.

  • Leucaena leucocephala (lam. de Wit) is a multipurpose leguminous tree/shrub, promoted extensively for reforestation and rural development programmes, as well as in ruminant production. After a year of establishment in the plots, the overall leaves and twigs yield was on average 0.92 kg/plant, containing an average 23.34, 10.61, 5.32 and 10.13 percent CP, CF, and ash, respectively. The proximate and mineral compositions are affected by factors such as stage of maturity, type of cultivar, seasons, cutting intervals, different plant parts. Though leucaena contains toxic mimosine and tannins, these are not always deleterious for ruminants and rumen microbes can often degrade toxic factors into a nontoxic utilizable product Mimosine content is generally higher in the seed than other plant parts. Leucaena supplementation in ruminant ration showed higher digestibility co-efficient of proximate component, which may results in higher productivity. Considering its productivity, composition and nutritive value. L. Leucocephala could be more widely used as a protein source for ruminants in tropical and sub-tropical countries.

  • A technique for detection of Xanthomonas axonopodis pv. citri, a causal bacterium of canker on Unshiu orange fruits, was developed using bacteriophage. Procedure for the detection was designed on the basis of the previous reports that one group(CPI) of X. axonopodis pv. citri bacteriophage and corresponding two Iysotypes distributed in Korea. First, fruit surface was washed with sterile distilled water and pellet was obtained from centrifugation. The pellet was resuspended in Wakimoto's potato semi-synthetic broth medium and divided equally into two parts. One part was heated in boiling water to kill bacterial cells. Bacteriophages(CP$_1$) were respectively added into two parts and 0.1 ml from each part was mixed with soft agar medium. After incubation for 18 hrs at 25$^{\circ}C$, the causal bacterium of canker was determined based on plaques formed on the medium. This procedure can be effectively used for detection of living bacterial pathogen on fruit surfaces of Unshiu orange.

  • Antioxidant activity of the extract fractions from leaves, stems, roots and flowers of Cirsium pendulum Fisch. was investigated. The results showed the greatest antioxidant activities in leaves by Rancimat, TBA and DPPH methods. Extracts of common thistle plants dose-dependently increased DPPH free radical scavenging activity, The extract from flowers and its hexane fraction showed the strongest antioxidant activity. HPLC analysis showed that BuOH fraction of the leaves had the highest amount of antioxidant chlorogenic and p-coumaric acids at 5.38 and 9.71 mg $100\;g^{-1}$, respectively. It implies that common thistle plants had potent antioxidant activity, and their activities were differently exhibited depending on plant part and solvent fraction.
