  • Seasonal variation of marine bacterial community was analyzed in the surface sea water collected from one of the stations locating at Tongyeoung coastal area, Korea. The results obtained by the culture method through identification with the VITEK Microbe ID system after pure culture in the selective medium were compared with those obtained by the DGGE based 16S rRNA PCR method. The composition of the marine bacterial community in the sea water samples harvested in September, 2004, November, 2004, January, 2005, May, 2005 and August, 2005 determined by the culture method showed 5, 5, 4, 6, and 10 strains respectively. Pseudomonas fluorescens and Acinetobacter lwoffii were detected in all seasons. The other strains were identified to be Pseudomonas stutzeri, Sphingomonas paucimobilis, Burkholderia mallei and Chryseobacterium indologenes. In contrast, the 16S rRNA PCR-DGGE method detected 10, 11, 6, 9 and 13 populations respectively in the same sea water samples and the strains were identified to be Acinetobacter lwoffii, Burkholderia mallei, Pseudomonas fluoresence, Actinobacillus ureae, Burkholderia sp., Pseudomonas stutzeri, Roseobacter sp., Vibrio parahaemolyticue, Sphingomonas paucimobilis and Rugeria algocolus. This results indicated that the DGGE based 16S rRNA PCR method was more efficient than the culture method for the grasp of the characteristics of the marine bacterial community.

  • This paper presents an emerging concept, professional mobility in S&T innovation system, that focus on the utilization of highly qualified researchers without recruiting. In this paper we divided the utilization of external researcher into four types: (1)visiting/post-Doc/guest researcher, (2)collaborating research student, (3)part-timer or trainee and (4)foreign researcher. From 2002 to 2005 in 19 Korean government-funded research institutes, while total researchers have increased by 13.3%, external researchers have decreased from 39.2% to 35.7%. In 2005, visiting and foreign researchers were only 6.5% of total external researchers. It may indicate that the innovation capability of Korean research institutes is on the quite limited situation compared to foreign research institutes. The financial and institutional support programs for promoting the professional mobility are also insufficient in Korean S&T innovation system.

  • The purpose of this study is twofold. First, it shows how to calculate the size of nonregular workers in Korea using the supplemental surveys to the Economically Active Population Surveys. Second, it decomposes the difference in the share of nonregular workers between 2005 and 2013 by a Oaxaca-type method.. The obtained results indicate that the differences in coefficients rather than the differences in characteristics are mainly responsible for the decline in the share of nonregular workers. This implies that a worker with the same characteristics is more likely to be a regular worker in 2013 than in 2005. This tendency may come from the changes in workers's as well as firms' employment practices. Also, it is suspected that the Nonregular Worker Act enacted in 2007 may have contributed to the decrease in the share of nonregular workers.

  • The purpose of this study is to validate the effect of improvement such measures as fence installation or planting of bush and herbaceous plants taken from Pinus densiflora forest in Solbat Neighborhood Park in Seoul, which was damaged by stamping. The study was conducted in 2005 and 2010 in order to analyze changes in planting types, planting structure of Pinus densiflora forest, soil hardness, cross-sectional structure of soil, and physicochemical characteristics of soil. It was also measured by the growth of the branches and the diameter of Pinus densiflora, comparing before and after the improvement to study the effect of restoring Pinus densiflora forest damaged by stamping. When it comes to a change in planting type, Pinus densiflora forest without underlay was reduced from 48.5% in 2005 to 6.8% in 2010. Pinus densiflora forest with bush and herbaceous plants was increased dramatically from 7.4% to 46.8%. Regarding planting structure, in most area of the subject site, Pinus densiflora forest without under layer was transformed into the one with bush and herbaceous plants including Rhododendron mucronulatum, Rhododendron schippenbachii, Hemerocallis fulva, Aceriphyllum rossii, Hosta plantaginea growing in a wide area. The soil in the Solbat Neighborhood Park was very stiff with soil hardness of $54.8kg/cm^2$ in average. After the improvement efforts made in the Park in 2010, the soil hardness was mostly less than $4kg/cm^2$, being in a good condition with little influence on the growth of plants. When it comes to the cross-sectional structure of soil, litter layer didn't exist in 2005 because of stamping and the organic matter layer was only 1.0cm thick, which provided an unfavorable condition for plant growth. However, after improvement, litter layer was formed up to 3.0cm and thickness of the organic matter layer also went up to 1.5~8.0cm in 2010 because the damage from stamping was reduced. Concerning the physicochemical characteristic of soil, in 2005 soil showed pH 5.76~6.70, organic matter content 7.15~10.55%, and available phosphorus 9.38~26.47mg/kg, having no big problems as a soil environment for growth of Pinus densiflora. 15 trees of Pinus densiflora were selected to see branch growth and it was found that the branches tended to grow better after improvement. 70 trees of Pinus densiflora from various grades of soil hardness also were selected to identify changes of diameter growth. In most cases, it was analyzed that Pinus densiflora grew better after improvement. After conducting this study, it was validated that such measures as fence installation or planting of bush and herbaceous plants to restore Pinus densiflora Forest damaged by stamping were effective in improving growth of Pinus densiflora.

  • This study estimated the forest damage of Kangwon-Do fire disaster occurred April 2005. For the estimation, the delineation of fire damaged area was performed using SPOT-4 satellite image and DSM (Digital surface model)/DTM (Digital Terrain Model) was generated by airborne and ground LiDAR data to calculate forests height. The damaged amount of money was calculated in forest area using stand volume formula, combining the canopy height from forest height model and digital stock map. The total forest damage amounted to 3.9 billion won.

  • Current status on the occurrence and the management of the major disease, insect and mite pests were investigated in the organic or non-chemical pest control orchards from 2005 to 2009. Numbers of certified organic or non-chemical apple orchards were increased from 14 in 2005 to 78 in 2008. Severe damages on leaves and fruits occurred by the several diseases such as marssonina blotch, bitter rot, white rot, sooty blotch and flyspeck, and the several insect pests such as apple leaf-curling aphid, woolly apple aphid, oriental fruit moth and peach fruit moth on the almost certified organic or non-chemical pest control orchards. About 10 and 18 environmental-friendly materials were used to control diseases and insect or mite pests respectively. But, lime sulfur and bordeaux mixture to diseases and machine oil, plant oil mixed with egg yolk, and pheromone mating disruptions to insect pests were effective to control under the adequate conditions. At present, it is extremely difficult to produce organic apples in Korea. Growers must consider about and solve so many conditions on the cultivar, weather, local site, marketing and so on, before when they decide to change from conventional or IPM(Integrated Pest Management) to organic or non-chemical pest control orchards.
