  • 최근 도시유역의 홍수들이 빈번히 발생하고 있다. 2010년 2011년에는 서울 지역에서 연이은 도시 홍수피해가 발생하였고, 2015년 미국 South Carolina, 프랑스, 중국 지역에서 많은 홍수 피해가 발생 했다. 도시유역에서 홍수피해가 증가하고 있는 주요 원인은 기후변화로 인한 극한 홍수의 증가, 도시화로 인한 불투수면적의 증가, 배수관망의 통수능 부족 등이라 할 수 있다. 본 연구는 앞서 제시한 세가지 원인들 중 불투수면적의 증가 및 배수관망의 통수능 부족 부분에 대하여 기존 연구와는 다른 시각으로 접근하여 도시유역의 홍수유출 저감방안에 대한 연구를 수행하였다. 본 연구에서는 서울의 신월 배수분구를 대상으로 첫 번째 불투수지역들 중 강우발생시 홍수유출에 직접적인 영향 미치는DCIA(Directly Connected Impervious Area)지역과 IIA(Isolated Impervious Area)를 분리하여 홍수유출 특성을 분석하였고, 두 번째는 배수 관망의 통수능 부족 문제를 해결하기 위해서 관망의 통수능을 증가시키는 방법이 아닌 홍수 유출을 저감할 수 있는 적정 배수관망 레이아웃을 산정한 후 이를 SWMM 모형에 적용하여 기존 배수관망 시스템과 적정 배수관망 시스템의 홍수저감량을 비교하였다. 마지막으로는 첫번째 방법과 두 번째 방법을 동시에 적용하였을 때의 홍수저감량을 검토하여 최적의 도시유역의 홍수유출 저감방법을 제시하고자 한다.

  • In the midst of recent active excavation, lots of Silla(新羅) roof-end tiles are unearthed in Yeongnam area(嶺南地域). These are confirmed the same tile frame as the Silla tiles excavated in Gyeongju(慶州). It is represented by the Silla tiles excavated in Ingaksa Temple(麟角寺) excavation research. Roof-end tile with arabesque design(唐草文平瓦當) etc. including roof-end tile with lotus design(蓮花文圓瓦當) are judged to be the tile frame produced by the same frame of roof-end tile that was excavated in Gyeongju, Wolseong(月城) and Hwangyongsa Temple(皇龍寺址). There are three kinds of cases concerning the transportation of tile manufacture ; the roof-end tile manufactured in Gyeongju directly moved to each region, only tile frame moved to site to be manufactured there, and tile manufacturer moved to site to manufacture there. This article considers the case of the roof-end tile manufactured in Gyeongju that was directly moved to each region. In case of the Silla tiles excavated in region especially Ingaksa Temple, the aspects of tiles in accordance with different era show the repeated coexistence, expansion and maintenance. This situation is significant as a clue to understand the supply from Gyeongju not as temporary, but as continuous. On the other hand, if the Gyeongju tiles flowed directly into each region, and if the road was built of gravels and the means of transportation was cart, the damage from movement must never be prevented. On the contrary, transportation through waterway might be advantageous due to the reduction of labor and damage rate and the easiness of loading. Accordingly, it tells us why the ruins where roof-end tiles were excavated located near big and small rivers or streams. Of course there are some ruins located in a fixed distance, but the distance may be enough to endure the impact put on tiles from the overland movement. Therefore, in case of direct inflow form long distance, transportation must be finished by overland movement after waterway movement.

Characteristics of Indigenous Rhizobium to Korean Soils -I. Symbiotic Potentials of Bradyrhizobium japonicum Populations and Their Colony Morphological Characteristics in Yeongnam Soils (우리나라 토착근류균(土着根瘤菌)의 제(諸) 특성(特性) 연구(硏究) -I. 영남지역(嶺南地域) 토착(土着) 대두근류균(大豆根瘤菌)의 접종효과(接種效果)와 취락형태적(聚落形態的) 분포특성(分布特性))

  • Soybean [Glycin max (L.)] cv. Jangbaekkong was inoculated with 5 cultivated- and 5 uncultivated upland soils, in Yeongnam area, as soil inoculum and NifTAL peat inoculum as standard for soil inoculum potentials by Bradyrhizobium japonicum. 120 Bradyrhizobium japonicum isolates out of the soil populations were scored of three colony morphologies, designed "Dry", "Wet", and "Dry/Wet", and symbiotic effectiveness between "Dry" and "Wet" was compared. The results obtained were summarized as follows: 1. Indigenous populations of B. japonicum were above $10^4cells/g$. soil at the cultivated upland soils but were a few at the uncultivated upland soils except a colluvivum, orchard previously, in Yeongnam area. 2. Inoculum potentials of the cultivated upland soils were higher than the NifTAL inoculum and generally, nodule mass compensated nodule number for symbiotic effectiveness of soil populations. 3. Colony morphologies of soil populations showed the different proportions of "Dry" and "Wet" so that "Dry" types were dominant at the cultivated upland soils while "Wet" types at the uncultivated upland soils. 4. "Dry" colony morphology significantly exhibited higher symbiotic effectiveness than "Wet" types in nodule fresh weight, shoot dry weight, and shoot dry weight/nodule fresh weight. Therefore, as long as soil inoculum potentials, the growth of soybean at the cultivated upland soils could presumedly be affected by soil populations of Bradyrhizobium japonicum of "Dry" colony morphology.

  • This study examined the relation between MBTI personality types and job satisfaction, job satisfaction's effect on the customer orientation and willingness to change job and MBTI personality types's moderating effect on the relation among job satisfaction customer orientation, willingness to change job. Research results are as following. First, MBTI personality types didn't influence job satisfaction significantly. Second, job satisfaction affected customer orientation positively and willingness to change job negatively. Finally, MBTI personality type's moderating effect was analysed using Psychological Function and Attitude Index. Moderation effect of Psychological Function was significant only on the relation between job satisfaction and customer orientation. Moderation effect of Attitude Index was significant both on the relation between job satisfaction and customer orientation and the relation between job satisfaction and willingness to change job. These results of current study can be useful to recruit, organize, educate life planners based on the personality types of MBTI. And the applicability of MBTI test will increase by using these results.

  • To evaluate bacteriological water quality of groundwater in Yeungnam Province, samples were taken from 123 locations during summer and 117 locations during winter. The medians of heterotrophic plate counts.(HPCs) were 30 CFU/mL for the summer samples and 40 CFU/ml for the winter, and more than 25% showed HPCs higher than 100 CFU/ml. Coliform bacteria were detected from 46% of the summer samples and 30% of the winter. In these coliform-positive samples, the medians of coliform counts were 20 CFU/ml for the summer samples and 4 CFU/ml for the winter. Genera such as Citrobacter, Enterobacter, Escherichia, Klebsielia, Pantoea, Rahnellia, and Serratia were identified from the coliform isolates; among them, 48% were members of the genus Enterobacter. While E. cloacae, E. amnigenus, and K. pneumoniae were the most frequently isolated species, E. coli was isolated only from 1 location. The coliform counts were positively correlated with the HPCs, which also positively correlated with water temperature. The results of present study provide further insight on the extent of groundwater contamination with coliform bacteria.

  • A new peanut variety "Charmpyeong" (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was developed from the cross between the high-yielding cultivar "Shindaekwang" and the very short stem cultivar "ICGV94216". This Virginia plant typed "Charmpyeong" has 33 cm stem height and 18 branch number Each pod with ellipse-shaped large kernel has two grains with brown testa and 100 seed weight was 88 g in the regional yield trials (RYT). This variety also showed more resistant to web blotch compared with check one. Especially it has resistance to lodging until harvesting owing to short stem. In the regional yield trials "Charmpyeong" was outyielded than check variety by 13% with 4.35 MT/ha for grain.
