Economic Lot size decision is studied on this thesis foe the muti-product small batch production system. Even though economic lot size decision has been studied for the MRP system. this could be applied at the industry under the multi-product small batch production system because of very complicate and manager's lack of understand. Therefore, this technique is applied at the industry in order to minimize ordering cosy based on optimal quantity and period, and holding cost according to optimize inventory level under the muti-product small batch production system. After that, lot size decision technique is compared with lot size decision technique which has been used for analyzing and emphasizing productivity

A rotational force generator for molten metal is developed using a linear motor design technology. Also, the developed device is applied to reproduce aluminum scraps and easy to control the rotate, stop, and forward and reverse rotation of molten metal. In addition, the developed device improves the melting speed and reproduction rate about 250 (%) and 96-99 (%), respectively, compared to the conventional handmade methods. Because it generates almost no dusts, it can improve working environments in a factory. Also, it has no losses in energy because it directly melts scraps. The device generates small amounts of the loss in refractory materials and aluminum caused by its oxidation because the molten metal is continuously rotated in which the loss and oxidized aluminum are the problems in the conventional melting and holding furnaces. Thus, it is possible to extend the life of furnaces and to produce high quality aluminum products.

We, in this paper, suggest the Yeosu internationalization strategy for holding the 2012 World EXPO in Yeosu successfully, First of all, we analyze some problems that hinder the internationalization of Yeosu. Our analysis, also, provides several strategic solutions to those problems by foreign direct investment, international trade, hub port development, and international tourism. first strategy is to create a more favorable business environment for foreign investors. Foreign direct investment is the most effective way to internationalize the specific district. Second strategy is to expand the export of small and medium-sized firms in Yeosu. Especially, local firms with agricultural/fishery products have to develop various new products and introduce the effective international marketing strategy. Final strategy is to develop the hub port in Yeosu and the new tourist resources to attract foreign tourists.

Recently, during several years the number of ideal children have not changed at all. Because the most of Korean people considered that son is necessary absolutely for dependence in old age inheritance of family line and holding ritural and so on. Threfore, without revolution of value system for children we could no more expect to reduce fertility rate. The survey is intended to compare the characteristics between those women who want two or less number of ideal children and all married women(regardless the number of ideal children). The results showed as follows: The women who want small size of family were younger and little better educated than those of all married women. The age at marriage of women who want small size of family was older than that of all married women. The conducted rate of induced abortion and acceptance rate of contraception among those women who want small size of family were higher than those of all married women. The rate of those who want less than 2 children socalled ideal No. among all married women was 3.9 percent.

We studied about the difference of division public announcements by corporation size and ownership structure from 1999 to 2005. The results is as follow : First, we found most positive numbers in division corporation's CAR. This supports the existing research that corporation division is evaluated positively in the market. We found CAR as largest shareholders' holding more than 40%, which is greater than 0-20% & 20-40%, that shows relatively more negative CAR. So, the exceeded largest shareholders' holding rate (i.e., over 40%) can be a factor for decreasing corporations' value. Also, most positive CAR shows relatively small variation regarding corporation size knowing that big sized corporations have relatively small variation than small sized corporations. Second, we studied about relationship between corporate ownership structure and division public effects and found relatively a little effect by large shareholders, foreign investors' holding variables on division public.

Goats have long history in Korea. But because of small holding, is there no systematic development for breeding and reproduction. The most of goats in Korea have some typical problems, which gradually appeared through inbreeding. The purpose of this study was to evaluate effects of hormonal treatment on estrus synchronisation in non-breeding seasons and to estimate economical aspects of caprine embryo transfer. Otherwise we would like to develop a suitable practical method of field embryo transfer, in order to obtain the more basical breeding materials for high-performance goat. (omitted)

We introduce a rotating-gantry-based x-ray micro-tomography system to be used for small animal imaging studies. It has the zoom-in imaging capability for high resolution imaging of a local region inside the animal subject without any contrast anomalies arising from truncation of the projection data. With the sliding mechanism mounted on the rotating gantry holding the x-ray source and the x-ray detector, we can control the magnification ratio of the x-ray projection data. By combining the projection data from the large field of view (FOV) scan of the whole animal subject and the projection data from the small FOV scan of the region of interest, we can obtain artifact-free zoomed-in images of the region of interest. For the acquisition of x-ray projection data, we use a $1248{\times}1248$ flat-panel x-ray detector with the pixel pitch of 100 mm. It has been experimentally found that the developed system has the spatial resolution of up to 121p/mm when the highest magnification ratio of 5:1 is applied to the zoom-in imaging. We present some in vivo rat femur images to demonstrate utility of the developed system for small animal imaging.

Dietary powder from Plantaginis ovatae testa was prepared by mechnical milling/grinding of the outer layer of the seed. The crystalline/surface structures of its powder (100 mesh) were examined, and several physical functionalities including, water capacity, oil holding capacity, emulsion/foam properties and physiological functionality such as in-vitro glucose and bile acid retarding effects were also investigated. Water holding capacity(WHC) of psyllium powder was $33.71{\pm}0.10g$ water retained/g solid at room temperature, whileas oil holding capacity(OHC) for soybean or rice bran oil were about 1.80g oil retained/g solid. These values of WHC and OHC were about 5.6 times higher and 2.8 times lower than those of commercial ${\alpha}$-cellulose, respectively. Changes of pH showed a small effect on WHC, but WHC increased with temperature. Emulsion capacity of 2%(w/v) psyllium was about 60% level of 0.5%(w/v) xanthan gum but emulsion stability after incubation of 24 hours showed about 1.4 times improvement of xanthan gum(0.5%,w/v). Also, psylliume(above 2%, w/v) alone had higher foam capacity than that of xanthan(1.1 times) and especially, 1 or 2% addition of psyllium improved the foam stability of protein solution(1% albumin+0.5% $CaCl_2$) by factor of 3.3 and 6.0 times, respectively. The glucose and bile acid retarding effects of psyllium powder were relatively very excellent suggesting the prevention from diabetes and arteriosclerosis. Especially, psyllium showed the 3.7 and 3.3 times higher effect on in-vitro glucose and bile acid retardation than those of commercial ${\alpha}$-cellulose, respectively.

It is said that anchovy of 6 to 7 em in body length is the most suitable for the live bait in skipjack pole and line fishing, and it must be held in a creel for more than 7 days so as to be transported from the holding ground to the fishing ground, kept in the small bait hold in a fishing boat. To hold the live bait anchovy, holding creel should be settled in calm waters, and then it is necessary to investigate the appearance of the available resource in the south-eastern coastal waters of Korea where the creel can be settled. The authors investigated the app~arance of the available resource in the waters, and the following results are found. 1. The available resource appears more and the fishing season is longer than in the offshore, rather than in the inshore. 2. The available resource arc caught in the offshore with the passing of time into winter, and they are caught merely in the offshore side in December. 3. The available resource could be secured from July to December, somewhere in the south-eastern coastal waiers of Korea, if the holding ground were removed appropriately.
