To design parts satisfying physical property in the continuous region, we do it in the discrete rectangular mesh points. Then we obtain points data from parts design and usually construct the surface using least squares method. In such case, that surface has an oscillation in the ineffective region which is inadequate for physical phenomena or NC machining. To solve both problems simultaneously, we extend the surface smoothly to have small curvature in the extended region. Up to now, we use the least squares method for the parts design in Color Picture Tube or Color Display Tube but in this paper, we use functions which is easily controllable. This surface has no error within the effective region compared to the least squares method.

The experiment was carried out to select the rice cultivar adaptable to Top Rice cultivation region from 2006 to 2007 in Useong and Kyeongju, Korea. Four cultivars, recommended for high rice grain quality, were cultivated in the different region in this study. The average yield of head rice was higher in Samguangbyeo than the other three cultivars. The protein content was inversely associated with palatability (Toyo value). The protein content of Samguangbyeo was 6.2%, which was the lowest among the tested cultivars. L values in color of rice and cooked rice were not significantly different. The hardness of Samguangbyeo was lower than that of the other cultivars in texture properties of boiled rice on 4 cultivars. In conclusion,considering the rice yield and grain qualities, Samguangbyeo was selected as promising rice cultivar for Top Rice cultivation region.

The purpose of this study is to analyze the residential space composition and extension of Jeonja-jip and Dureong-jip in Samcheok region. The results of this study are as follows. It appears three residential plan types - Jeonja-jip with Anmaru(a room made of wooden floor), Jeonja-jip without Anmaru and Dureong-jip with Anmaru- in survey region. It was needed the extension of residential space at Jeonja-jip(a house type with two-row rooms which be composed of 田type under one roof) and Dureong-jip(a house type with inner floor which be surrounded by rooms under one roof) because of shortage of sleeping space, working space and keeping space owing to growing large family. The solutions of these shortages will be the extension of space in houses. Jeonja-jip's basic type which is the Kyup-Jip(a house type with two-row rooms under one roof) of 一 type with 6 Kans(Kan, a unit to count room to divided with four posts) is transformed and extended to 田shaped house with 11 Kans toward X-axis orientation. Dureong-Jip's basic type which is ㄱ type with 7 Kans is transformed and extended to the Sekyup-Jip with 9 Kans and the Nekyup-Jip(a house type with four-row rooms under one roof) with 12 Kans toward Y-axis orientation by insertion and addition. Jeonja-jip was developed into Kyup-Jip with front 4 or 5 Kans and side 2 Kans instead of being done into Sekyup-jip or Nekyup-Jip with insufficient day lighting and ventilation problems. Jeonja-jip and Dureong-jip were stronger than any other traditional houses in tendency to reserve Magu(cowshed) and Chikkan(toilet) in a house.

The isometric area of the anterior cruciate ligament was calculated during knee flexion-extension. Flexion-extension motion data of the joint were obtained using Fastrak and a three-dimensional motion measurement system. A total of five subjects were seated on a flat table and the tibia sensor position was measured with the femur fixed on the table. A three-dimensional knee model was constructed using a graphic tool to simulate the knee motion. Twenty seven positions of the tibia region and forty two positions of the femur region were selected and the distances between the determined tibial and femoral points were calculated. Highly isometric areas were found and displayed as three dimensional aspects.

The Bering Strait crossing would link the entirety of Eurasia to the entirety of the Americas, and it can be seen as a natural extension of the historical Silk Road. There are some immense geopolitical benefits to such a project. It would bring about a profound and lasting change to the global economic and political outlook. The most valued function of the Bering Strait crossing and the extension of the associated railroad network would be to release the massive natural resources trapped underneath the tundra and permafrost for the benefit of Russia and the world. Moreover, the railroad project(s) would also build development corridors in those underdeveloped parts of the Russian Federation. The development of the resources and their rapid transportation to the global markets would contribute not only to the overall development of the region but also would be valuable for the resource-poor countries of Northeast Asia such as Japan, Korea, and China (relative to its economic size). This paper will explore the possible impact(s) of the Bering Strait crossing as a formidable infrastructure project for the economic development of the Russian Far East (RFE) from the Russian perspective under the frame of geopolitics. Furthermore, it will equally scrutinize the implications for the adjacent countries in the region.

The purpose of this study was to classify the type of customer which is essential to agricultural extension service, specify their needs and identify the performance level of public agricultural extension organization by the needs of customer. To meet these purpose, we conducted a focus group interview and surveyed the agricultural extension workforce. The results of this study are as follows. First, we classify the customer of agricultural extension service as 9 types. Second, the needs by customer types are specified 12 types. Third, those who attached to Rural agricultural development administration and agricultural research and extension service organization in provinces recognize them selves as more performing organization than agricultural technology center in region, except one area.

Korean agriculture now faces a historic challenge due to globalization and decentralization. Agricultural cooperatives should be reborn to lead regional agriculture by reorganizing the regional agri-business and strengthening the competitive power of regional agriculture. It also needs to establish an integrated agricultural development plan and to expand the vision for future agriculture. To pursue these objectives, Agricultural Cooperatives should work together with the regional government and develop an enterprise with a competitive advantage in the region.
