  • The Korean government continuously increases the R&D investment in order to pursue an economic growth through technological innovation. Hence, the intensity of governmental R&D has increased rapidly. However, the whole amount of the R&D investment is still small compared to developed countries. And the type of R&D policies is more and more changing from the catch-up model to the technology-driven model. Therefore, there is a growing interest in the efficiency of public R&D investment. Hence, many studies on the efficiency of R&D investment have been researched. This study estimated the efficiency of governmental R&D programs considering the technological outcomes, e.g. theses, patents and so on, using DEA(Data Envelopment Analysis) with data of S&T investment and outcomes from NTIS(National S&D Information Service). In addition, we used the Mann-Whitney Test to investigate the characteristics of governmental R&D investment.

  • Topographic changes in the foredune in Sohwang-ri, Boryeong, Chungnam Province was analyzed over the last two years. Seven cross-sections and one permanent plot ($20m{\times}50m$) were periodically studied based on erosion and deposition measurement, in addition to vegetation monitoring and measurement of wind using an automatic weather station. The sand dunes usually grew from late winter to spring and the growth occurred in a period of strong northwesterly winds. From March to April, heavy sedimentation was observed on the front section of the foredune and sand piled up to ca. 30cm to the ca. 25m landward from the high tide line. It is likely that increased wind force and growth of vegetation played a major role in transportation and sedimentation of sand. Meanwhile, the lower part of the sand dunes was eroded when typhoon and spring tide caused a rise in sea level. The transition zone of beach and dune was usually affected by sea water but some frontal slopes were entirely influenced, resulting in dune scarps. The eroded scarps were naturally restored to their original state as time passed.

  • A computer simulation was carried out to investigate the optimum capacity of liquid manure tank spreader which is used as a tractor attachment. Soil physical properties, such as soil moisture content, bulk density, soil hardness and soil types were measured in the 10 major rice production area for computer simulation. Mathematical model which include soil physical properties and vehicle factor was used for computer simulation. Most of the soil type of the investigated area was sandy clay loam. Soil moisture content ranged between 30 and 40% mostly. Soil bulk density was in the range of 1,500 to 1,700 kg/$m^3$. Soil hardness ranged between 1 to 18 $cm^2$. Soil hardness incorporate the effects of many soil physical properties such as soil moisture content, soil type and soil bulk density, and so the range of soil hardness is greater than any other physical properties. The capacity of liquid manure tank spreader was above 3,000 kg$_{f}$ for the most of the investigated areas, and mostly in the range of 4,000 to 6,000 $kg_f$ depending upon the slip. But for the soft soil area such as Andong and Asan, the tractor itself has mobility problem and shows no pulling force for some places. For this area, the capacity of liquid manure tank spreader ranged between 1,000 and 2,000 $kg_f$ mostly, so the capacity of liquid manure tank spreader should be designed as a small capacity trailer compared to the other area.mpared to the other area.

  • Immersion is the key factor in determining success or failure for fictional narrative animations. It does matter to not only for the socio-economic achievements like box-office success but to the asthetical achievement, immersion is very important prerequisite character that are raised in terms of research needs. Fictional narrative animation shares the audience's immersive method with the narrative content and Virtual Reality, since animation has the character which narrates itself with the visual image format (including sound) and added the fact that 3D format which emphasizes realism compared with the recent 2D animation has been ubiquitous phenomenon. In other words, the artistic for called 'animation' is located between the view point that text has the immersive point intrinsic and oppositely, specific function of the certain media which stays extrinsic of the text enforce the participants into the immersion. In any case, the subject who experience immersion is the audience, so the most useful theory to research the phenomenon 'immersion' is Constructivism cognitive narrotologic approach which lies the peader-spectator as the centric notion and is more useful than text analysis or research on the visual effects. In this study, research and review about the studies on the audience's immersive experience would be preceded particularly aroud the constructivism theories, and examine the uniqueness and naures of the animation which makes the audience immersive.

  • This study was conducted to analyze the genetic characteristics of the Jeju dog for preservation and protection. A total of 139 dogs from 7 dog breeds, including the Jeju dog, were genotyped using 16 microsatellite markers. The results revealed 2-18 alleles per locus, with a total of 131 alleles among the 16 markers. Most alleles were identified for FH3381, which had 18 alleles, whereas FH2834 had the fewest alleles, with just 2. When the total mean value was observed, the expected heterozygosity and observed heterozygosity were higher for than for outgroup dogs, and the PIC values ranged from 0.000 to 0.862, respectively. The phylogenetic tree analysis of the Jeju dog and other dog varieties revealed that the Jeju dog is closest to the Sapsal dog (0.393). The phylogeny between the Jeju and Korean domestic dogs showed that the Jeju dog is most distant from the Dongkyung dog (0.507). Looking at the distribution individually, the Jeju dog is in the same group as the Labrador Retriever and the Sapsal dog. Meanwhile, the Poongsan, Dongkyung, and Jindo dogs and the German Shepherd were in the same group. Genetic information confirmed through the results of this study can be used as basic data to study the genetic characteristics of the Jeju dog.
