  • 본 연구의 목적은 N사의 파트너스퀘어(광주) 이용한 경험이 있는 청년자영업자를 대상으로 e-커머스 창업생태계인 온라인쇼핑몰에 진입하는 과정과 성과를 근거이론(Grounded Theory) 방법을 활용해 규명해 보는 데 있다. 본 연구는 심층 면접 조사 자료를 활용했는데, 연구 참여자의 선정에 있어 이론적 표본 추출(Theoretical Sampling)방식을 사용했으며, 스트라우스와 코빈(Strauss & Corbin)이 제시한 개방코딩, 축코딩, 선택코딩 순으로 진행한 후 패러다임모형으로 분석했다. 주요연구결과는 다음과 같다. 첫째, 부모가 e-커머스에 대해 잘 알지 못하거나 부정적이라도 자녀의 창업에 대해서 긍정적이면 자녀가 온라인쇼핑몰을 통한 자영업에 진입하는 것으로 나타났다. 그러나 부모가 e-커머스에 부정적이고, 자녀의 창업에도 부정적이면 자녀는 온라인쇼핑몰을 통한 자영업에 진입하지 못하는 것으로 나타났다. 둘째, 청년층의 e-커머스를 통한 자영업 진입과 성과 창출조건으로 e-커머스 활용능력이 중요한 것으로 나타났는데, 특히 N사의 파트너스퀘어(광주)는 e-커머스 활용능력을 증대시켜, 청년층이 온라인쇼핑몰을 통한 자영업 진입에 긍정적 영향을 주는 것으로 나타났다. 셋째, 청년층은 온라인쇼핑몰을 통한 e-커머스 자영업에 진입한 이후 단순한 매출액 증가 이외에 자존감 상승, 기회발견, 창의성 역량이 강화되는 것으로 나타났다.

  • The morphological characteristics of a larval fish (7.8 mm in body length) collected off Chuuk, Micronesia were highly similar to those of larval Omosudis sp., except fin development and body length. It was identified as Omosudis lowii by partial mitochondrial 12S rRNA gene analysis. The morphological traits of the larval fish validated by the molecular genetic marker will be informative for species-level identification of larval Omosudis lowii.

  • The mesocotyl elongation, having much effect on emergence and stand establishment in the direct sowing culture of rice, was investingated and summarized as follows: As to origin of cultivars, the average lengths of mesocotyl were 9.6 mm in the Indica-Japonica hybrid cultivars, 4.4 mm in the native cultivars and 3.2mm in the Japonica type, respectively. The mesocotyl lengths were tjereh, aman, aus, boro and bulu in order, with the mesocotyl lengths of 29.3mm and 5.4 mm in tjereh and bulu, respectively. The mesocotyl lengths were great in Baekkyungjo, Dadajo & Hejo among the native cultivars, in Sangpungbyeo, Paltal & Gokyangdo of the Japonica type and in Weonpungbyeo, Gayabyeo, Milyang 30 & Sujeongbyeo in Indica- Japonica hybrid cultivars, respectively. The mesocotyl length was the greatest at the seeds sampled I week after flowering (39. 3mm in length), and became decreased with the longer grain-filling. The mesocotyl elongated worse with the longer duration of seed storage regardless of seed maturity, and became longer at the 5$^{\circ}C$ storage plot than at the 15 and 25$^{\circ}C$ plots.

  • In this study, the assessment scheme has been developed to evaluate the ecological function of rivers which were changed by the river improvement project. The evaluating factors are composed of physical structure in river channels and ecological connectivity in river areas, and each value of the factors is quantified based on 4 and 2 variables, respectably. This scheme was applied to past (1918, before artificial river improvement) and present Mankyung River area. A GIS model was adopted for calculating, analysing, and presenting river ecological conditions using the 204 grids and 7 reaches in study area. Comparison results show that the evaluation grade was decreased in both factors after river improvement. The main causes of lower grade (from II to IV) for physical structure are the river straightening and crossing structures. The reduction (from II to III) in ecological connectivity grade effected by linear fragmentation due to roads and rails is found to be greater than areal fragmentation due to land-use. In particular, it is also found that a high degree of ecological connectivity in 1918 was distributed along the river, but that one in 2007 showed a tendency to scatter because of the construction of levee and increase of urbanized area.

  • The yeongok stream originates at the natural park, Mt. O-dae and flows to the East Sea of korea, normally maintaining I or II grade of water quality and its average water flux is 352,100 ㎥/d. However, the typhoon 'Rusa', which occured on 31 August 2002, changed its watercourse and configuration, and the ecosystem was deeply damaged. Moreover, the hydrological characteristics were once more transformed, and the ecosystem was secondarily damaged during repair-work of destroyed bridges and elevations. After the flood disaster, the species diversity diminished 17% for attached diatom and 44% for aquatic animals. However, the earth and sand, dug from river bed during intensive repair-work throughout the entire stream, made diversity drop to 32% for the diatom and the aquatic animals were wiped out. Especially, fishes were totally destroyed except for some species such as Moroco oxycephalus in the upper stream. The yeongok stream has little contamination source and short water residence time due to the short length and rapid slope, and consequently a temporary deterioration of water quality caused by repair-work may be rapidly recovered, but it needs a long time to restore the damaged ecosystem.

  • Experiments and research on genes have become very convenient by using DNA chips, which provide large amounts of data from various experiments. The data provided by the DNA chips could be represented as a two dimensional matrix, in which one axis represents genes and the other represents samples. By performing an efficient and good quality clustering on such data, the classification work which follows could be more efficient and accurate. In this paper, we use a bio-inspired algorithm called the Particle Swarm Optimization algorithm to propose an efficient clustering mechanism for large amounts of DNA chip data, and show through experimental results that the clustering technique using the PSO algorithm provides a faster yet good quality result compared with other existing clustering solutions.

  • The regulation of continuous and adjacent development was introduced to prevent unplanned and improper development and to protect environment in green zone and non-urban area that was deficient in infrastructure. Though it has been effective, it was repealed in 2011 by disorderly development problem caused by crafty tricks around restrictions. Alternatively, the Urban Planning Commission is now deliberating on the development permit, but there are still much to be resolved such as improper committee formation and abuse of power, insufficient green corridor preservation, a lack of use of planning information system, discordance between landscape management guidelines in laws, etc. Therefore, we suggest several ideas for improvement of development permit system as follows; intensive deliberation system in the Urban Planning Commission, integrated commission for green corridor prevention, early establishment of urban planning information system, making a development permission guideline to minimize discretional act of the Urban Planning Commission, etc.

  • In knowledge based society, information technology (IT) has been playing a key role in economic growth. In recent years, it is surprisingly notable that the source of value creation moved from hardware to software in IT industry. Especially, among many kinds of software products, the economic potential of open source was realized by many government agencies. Open source means software codes made by voluntary and open participation of worldwide IT developers, and many policies to promote open source activities were implemented for the purpose of fast growth in IT industry. But in many cases, especially in Korea, the policies promoting open source industry and its ecosystem were not considered successful. Therefore, this study provides the practical reasons for the low performance of Korean open source industry and suggests the pragmatic requisites for effective open source policy. For this purpose, this study applies soft system model (SSM) which is frequently used in academy and industry as a methodology for problem-solving and we link the problems with corresponding policy solutions based on SSM. Given concerns which Korean open source faces now, this study suggests needs for the three different kinds of government policies promoting multiple dimensions of industry: research and development (R&D)-side, supply-side, and computing environment-side. The implications suggested by this research will contribute to implement the practical policy solutions to boost open source industry in Korea.
