The recent financial crisis is not yet solved. Although economic conditions are improving, the real-economy is still frozen, and considering Korea's reality of relying heavily on external trade, hardships in the global economy fall entirely upon us. In particular, since developed nations like United States and the EU have intensified logistics security since the terror attacks on September 11, 2001 and can use it as a tool for protective trade, Korea with a high dependency rate on foreign trade needs to actively cope with changes to the trade paradigm in logistics security. This paper uses DAGMAR(Defining Goals for Measured Advertising Results), a model developed by the Association of National Advertisers(ANA) to measure the results of a communication campaign as its basic model, after partially modifying it to fit the paper's objective of conducting a more systematic analysis of awareness levels in Korean export enterprise regarding logistics security.

This study was directed to the Peizootics of Newcastle disease in Korea. Since 1960 New-castle disease epizootics have been observed at an interval of one or two years. The frequency of Newcastle disease outbreaks was related to the amount of the vaccine used, being the more sufficient vaccine produced the fewer outbreaks. Regional distribution of Newcastle disease outbreaks was most frequent in the capital area, being the center of poultry raising and Poultry product marketing, and infrequent in areas distant from the capital. Spreading of Newcastle disease appears to be mainly due to the movement of infected chickens. More than 60 percent of the total outbreaks of Newcastle disease diagnosed at the Veterinary Research Institute in Anyang were observed in young chickens aged less than 60 days. Improper vaccination, interference by maternally derived antibody with the immune response following vaccination, ana immaturity of immune systems of young chickens might have contributed to the results. This view was further supported by the findings that 23 percent of the total flocks experienced Newcastle disease were not vaccinated at all and, in vaccinated flocks, virtually all of the flocks were vaccinated by the drinking water method, which has been known less effective compared to individual application or spraying methods.

Voluminous studies have been carried out on the utilization of cellulosic materials as a raw material for the production of sugar or single cell protein. The structural complexity of the substrate generated problems in the research works as well as in the application of the results obtained in the researches. This review outlines the physical ana chemical properties of cellulosic materials obtained from researches in the field other them biology.

The analysis of nail nitrogen content reflected recent nutritional status. Therefore, estimation of nail nitrogen content has been previously reported in a small group of neonates ana school children. Nail samples were obtained from 52 economically middle and 21 low classes. The contents of nitrogen in their fingernails were determinded by micro-Kjeldahl method. Mean nail nitrogen content was $133.1{\pm}8mg/g$ in the middle class which is significantly higher than that of the low class $122.1{\pm}8mg/g$. The nitrogen contents of nails obtained in summer were found by analysis of variance and student's t-test to he lower than those obtained in winter.

This paper describes a Push-Pull type high fre-quency resonant inverter conposed of consolidation of boost converter circuit and resonant circuit. By using a boost converter circuit the proposed inverter can obtain a twice input voltage of reson ant circuit and reduce a secondary turn ratios. By using both boost-converter and switching device can be reduce by half. Also the ana-lysis of the proposed circuit was described by using normalized parameter and operating characteristics have been evaluated as to switching frequency and parameters. In the future this pro-posed inverter shows that it can be practically used as a power source system for the lighting equipment of discharge lamp induction heating applications.

As a pan of voice identification, this study is on the voices from four different groups of sisters. The purpose of this study is to observe and analyze if sister's voices are actually so similar, as many people believe, that it is more difficult to distinguish one from the other than those of unrelated speakers. And it is also aimed to find out what the clues are to decide whether or not the voices are those of the same speaker or of different ones. The result shows that the mean frequencies of $F_3$ and $F_4$ of examined vowels and F0, in some group of sisters, are analyzed similar, In aural test, many listeners took their voices for those of the same speaker.

The use of a marker gene in a transformation process aims to give a selective advantage to the transformed cells, allowing them to grow faster and better, and to kill the non-transformed cells. In general, the selective gene is introduced into plant genome along with the genes of interest. In some cases, the marker gene can be the gene of interest that will confer an agronomic characteristic, such as herbicide resistance. In this review we list and discuss the use of the most common selective marker genes on plant transformation and the effects of their respective selective agents. These genes could be divided in categories according their mode of action: genes that confer resistance to antibiotics and herbicides; and genes for positive selection. The contention of the marker gene flow through chloroplast transformation is further discussed. Moreover, strategies to recover marker-free transgenic plants, involving multi-auto-transformation (MAT), co-transformation, site specific recombination and intragenomic relocation of transgenes through transposable elements, are also reviewed.

Populations of plant-parasitic nematodes were evaluated in soil and root samples from areas planted with passion fruit, or covered with adjacent native cerrado vegetation, in five different cropping regions of the Brazilian Federal District. From July 2007 to January 2008, twenty samples had been collected in five Rural Centers (N$\acute{u}$cleo Rural-NR) planted with passion fruit. In five sites, samples were also collected in native cerrado vegetation. Specimens of nine genera of plant-parasitic nematodes (Meloidogyne, Helicotylenchus, Rotylenchulus, Scutellonema, Pratylenchus, Paratylenchus, Hemicycliophora, Xiphinema and Criconemoides) were found in the present survey. Important nematode pathogens, such as Rotylenchulus reniformis and Meloidogyne spp. were observed in the passion fruit plantations throughout five major producing regions of the Brazilian Federal District.

The purpose of this paper is to reduce the level of idling vibration on a steering wheel. In some cases, vibration on steering wheel is amplified due to the resonance between the first natural frequency of T-beam and engine idling speed. Using SDM(structural dynamic modification) technique, T-beam is redesigned to reduce its vibration. This paper used FRF(frequency response function) synthesis technique which is entirely dependent on experiment. But this method requires lots of test efforts to enhance its reliability of design. While combining this method with an analytic method. the experimental burden, the major drawback of FRP synthesis method, can be considerably relieved. Using ana1ytic sensitivity analysis, some effective modification regions are preliminarily chosen as candidate Positions where SDM can be applied to modify T-beam\`s dynamic characteristics.

The methodology of applying fabric stretch ratio in the grants pattern drafting was evaluated. The experimental fabrics employed in this study were 3 different knit fabrics with various stretch ratio in vertical or horizontal direction. The firm fitting pants pattern was modified by applying the fabric stretch ratio in vertical ana horizontal direction. The computer automatic drafting method was used for pants pattenl alteration. The suitability of the altered pattern was evaluated by the 7 clothing specialists, The results showed that fit of all experimental garments was improved in general. The garment which was constructed with the fabric having large difference between horizontal stretch ratio and vertical stretch ratio showed poor fit at crotch area. This result implies that computer aided pattern alteration is not appropriate when fabric stretch ratio is vary by the fabric directions.
