Scaled-up low-trans shortening (LTS) was produced by lipase-catalyzed interesterification. Blend of rice bran oil (RBO), palm stearin (PS) and high oleic sunflower seed oil (HO) with 1:2:0.9 (w/w/w) ratio was interesterified using immobilized lipase from Thermomyces lanuginosus (TLIM) in the batch type reactor at $65^{\circ}C$ for 24 hr, and physicochemical melting properties of LTS were compared with commercial shortening. Solid fat content (SFC) of commercial shortening (used as control) and LTS was similar at 9.56 and 8.77%, respectively, at $35^{\circ}C$. Major fatty acids in LTS were C16:1 (33.7 wt%), C18:1 (45.7 wt%) and C18:2 (13.4 wt%). Trans fatty acid content in the commercial shortening (4.8 wt%) was higher than that of LTS (0.5 wt%). After reverse-phase HPLC analysis, major triacylglycerol (TAG) species in LTS were POO, POP and PLO. Total tocopherol, ${\gamma}$-oryzanol and phytosterol contents in the LTS were 12.37, 0.43 and 251.38 mg/100 g, respectively. Hardness of LTS was similar to that of commercial shortening. Also, x-ray diffraction analysis showed coexistence of ${\beta}'$ and ${\beta}$ form in the LTS.

Eucalyptus plantations play a major role in the China's ecological, social, economic and other aspects and presently China is the second largest producer of Eucalyptus in the world next to Brazil. It was introduced as an ornamental tree during 1890 but later it became a commercial crop. During 1960s large number of Eucalyptus timber were used for railway sleepers and it was also used as shelter belt for rubber trees. It becomes one of the important national resources of commercial timber once the production reached to 5 million $m^{3}/yr$. Through Eucalyptus oil, it brought about 20% of foreign exchange. In the present study, it was aimed to estimate the Eucalyptus growing area in the southern Guangdong in China in terms of aerial extent and changes between 1991 and 2001 using Landsat TM and ETM+ data. Object based classification technique and subsequent temporal change detection analysis were followed to identify the changes between the periods. In the present study, the total area was divided into three classes viz., plantation area with trees, plantation area without trees and others. Object oriented classification was found to be more accurate in the present study. Overall increase of about 23.62 $km^{2}$ was noted between 1991 and 2001 in the plantation area. With reference to the present study area, the growth of Eucalyptus growing area was 7.4% in the 10 year periods. From this study it is clear that the area under Eucalyptus cultivation is growing considerably year by year in China. However, elaborate study must be conducted considering larger areas to accurately predict the growth of Eucalyptus growing areas.

He purpose of this study was to provide basic data for improvement commercial kimchi quality. To examine the consciousness of commercial kimchi, college students residing in the Jeonnam area were selected and asked to questionnaires. Commercial kimchi samples used included a total of 7 kinds which were fermented for 2 week at $4^{\circ}C$. A sensory characteristics included 10 items with a 5-score scale: color, savory taste, carbonated taste, sour taste, hot taste, salty taste, bitter taste, off-flavor, texture, and overall preference. 76% of the whole student liked kimchi, especially well-fermented kimchi(43.2%) and kimchi with fermented fish(48.6%). Participants liked savory(21.6%), hot(17.1%), and crispy(14.4%) taste. Their most favorite kimchi was the whole cabbage kimchi(26.1%), wild lettuce kimchi(0.9%) and watery kimchi made of sliced radishes(1.8%) were low in preference. 56.8% of participants had no experience in making kimchi. They mainly bought commercial kimchi in grocery stores(37.8%) or shopping malls(29.7%). They pointed out the addition of artificial sweeter(35.1%), insanitation, and discredit of kimchi materials(21.6%) as problems of commercial kimchi. The sensory characteristics of commercial fresh kimchi was significantly different in color($2.6{\sim}4.1$), and hot($2.3{\sim}3.8$), and salty($2.6{\sim}3.5$) with p<0.001. The sensory characteristics of $4^{\circ}C$-fermented commercial kimchi for 2 week was significantly different in color($2.7{\sim}3.9$), and salty($2.1{\sim}4.0$) with p<0.001. It was found that color, and hot, and salty taste had the greatest effect on the overall preference in non-fermented kimchi, and color and salty taste, in 2 week fermented kimchi

In this paper, we discuss about the implementation of CITIS(Contractor Integrated Technical Information Service) which is information infrastructure for CALS. CALS concept is introduced by DoD(Department of Defense, US) to exchange technical data of product's life cycle electronically. This CALS concept is accepted by commercial industrial area and considered as a part of global concept of Electronic Commerce. CITIS- a service defined by MIL-STD-974- is about to be implemented by commercial industrial society, too. But, until now there is a few sites implementing CITIS and especially in Korea. In this paper, we discuss characteristics of some CALS/CITIS implementation and solutions, and introduce ETRI-CITIS.

Recently, demands on civilian UAV (Unmanned Aerial Vehicle) has been increasing and appropriate communication system is required for the UAV. In this paper, the performance of the UAV communication system using commercial wireless mobile network is discussed. The main service area of the wireless mobile network is ground level however the flying range of the UAV is normally in high altitude. Because of this mismatch of service area the performance of the UAV communication system is degraded in high altitude. To compensate performance degradation of the UAV communications system in high altitude, adaptive array antenna is introduced which is able to overcome altitude limitation of the UAV communication system.
