          숙련형성 체제 유형 연구

          이영현 한국직업능력개발원 2001 직업능력개발연구 Vol.4 No.1

          The purpose of this study is to present a framework for the comparative analysis of training and skill formation systems. The recent literature on industrial organization provides a theoretical and methodological foundation for the study. Skills upgrading thesis and deskilling theory which assume that different countries tend to converge as nations industrialize dominated the literature. They have been challenged by various forms of cultural and institutional relativism. The "societal effect approach", which is based on cross-national comparison of organizational units, has identified quite a large cross-national variety of organizational forms and practices. Although it draws comparisons between different countries it is less systematic in the variables used to describe these differences. Based on previous approaches, this study identifies the main underlying relationships which influence national systems of skill formation. Four models of the skill formation process are identified: the market model, the corporatist model, the developmental state model, and the neo-market model. These models show how such a framework enables us to explain why different nations have different approaches to skill formation. On that basis, we can further understand the relationships between vocational education and training, and economic growth.

          Combined analytical and numerical solution for an elastically supported Timoshenko beam to a moving load

          이영현,김성수 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.7

          A combined analytical and numerical method is presented to get a response for an elastically supported Timoshenko beam to a movingload. The analytical steady-state solution as a particular solution is established and summed with the numerically calculated homogeneoussolution. A steady-state solution is sought analytically through the direct application of the Fourier transform to the moving step load. It is shown to be a compact formula composed of exponential and sinusoidal functions depending on the load velocity. The homogeneoussolution is established numerically to cancel out the discontinuities and the inconsistent boundary and initial conditions of the steady-statesolution. The discontinuities produced by the steady-state solution are removed using the physical characteristics related to the bar wave. Some response curves are shown to compare the beam motions at different load velocities.

          캬드뮴 처리가 몇 가지 화단국의 생육과 카드뮴 축적량에 미치는 영향

          이영현,이종화,양의석,이택용 인간식물환경학회 2009 인간식물환경학회지 Vol.12 No.4

          his study was conducted to investigate the evaluation of Dendranthema grandiflora 'Branivory', 'Geumbangul' and 'White miri' which were reported to have good phytoremediability of cadmium contained soil. Growth responses of shoot length were found that the increase of 'White miri' was 216mm in control and 196mm in Cd treatment after 16 weeks and in fresh weight of top part was showed 23.7g in compared with 'Branivory' and 'Geumbangul' with Cd contaminated soil after transplant at 16 weeks. Different tendency was shown the change of soluble protein content when their growth period passed unlike the tendency of chlorophyll. The soluble protein content of 'Branivory' and 'Geumbangul' was much higher in the Cd treatment after 8 weeks. The chlorophyll content of 'Geumbangul' was the highest in 4.81 mg/g in the Cd treatment than other cultivar. The comparison of heavy metal accumulators in top of plants was as follows; 'Geumbangul'>'Branivory'>'White miri' after 8 weeks, and 'Geumbangul'>'Branivory'>'White miri' after 16 weeks. The choice of proper plants for bioremediation in different sources of heavy metal pollution seems important. In this regard, Dendranthema grandiflora 'Geumbangul' which showed higher in Cd accumulation of shoots could be used for phytoremediation and phytostabilization. 본 연구는 화단국을 이용하여 미적 가치를 제공할수 있는 관상식물의 중금속에 대한 생육 양상 및 중금속 축적 능력을 확인함으로써 오염지의 경광조성 및 환경친화적인 중금속 정화방법인 식물복원법 (phytoremediation)의 가능성을 규명을 위해 화단국인 도입품종인 ‘Branivory'과 국내 육성 품종인 ‘금방울’과 ‘화이트 미리’를 공시하여 토양 내에 Cd를 처리하여 생육량과 생리적 특성을 조사하였다.공시 3품종의 신초장은 Cd처리구에 비해 대조구에서 다소 높았고,특히 화이트 미리’는 216mm의 가장 높은 신초장을 보였고,Cd 처리구에서는 대조 품종인 ‘Branivory'에 비해 국내 육성종인 ‘화이트 미리’는 처리구의 16주에서 높은 196mm의 신초장을 보였다.지상부 생체중과 건물에서도 ‘화이트 미리’는 대조구에 비해 낮은 것으로 보였으나,다른 품종에 비해 16주의 Cd 처리구에서는 높은 23.7g의 생육반응을 나타내는 특성을 보였다.또한 식물체 내의 생리물질의 변화에 있어서는 수용성 단백질 함량은 Cd처리구에서는 전체적으로 대조구에서 그 함량이 증가하였으나,수용성 탄수화물에서는 시간별 품종간 차이를 보였는데 ‘Branivory’와 ‘금방울’ 에서는 8주차에서 가장 높은 경향을 보였다.엽록소 함량은‘금방울’ 품종에 있어서는 8주 대조구에서 4.81mg/g으로 가장 현저하였다.한편 Cd 처리구에서 생육량과 생리적 양상에서 다소 저해를 보였지만 축적량이 증가하는 경향을 보였고, '금방울’에서 8주의 2.88ppm, 16주의 7.04ppm 이었고, ‘Branivory'는 1.55ppm(8주),2.56ppm(16주)으로,‘화이트 미리’에서는 0.31ppm(8주),0.88ppm(16주) 순으로 품종간 차이가 현저하였다. 따라서 국내 육성품종과 도입품종의 간의 비교에서 토양오염지에서 국내 육성품종에 있어 생육상에서는 화이트 미리’가 우수한 생육반응을,중금속 축적에서는 '금방울’에서 우수함을 나타냄으로써 경관조성이 가능한 phytoremediator로서의 가능성이 있을 것이라 생각된다.그러나 또한 그 효과를 극대화시키기 위해 보다 많은 품종의 비교실험이 필요할 것으로 생각되며,인산,소석회,토양개량제 등의 첨가를 통한 토양내 bioavailability를 높이고 활착과 보다 많은 건물생산량을 높일 수 있는 연구가 뒤따라야 할 것으로 생각된다.

          輸出對象國 및 競爭國에 대한 花卉輸出動向 分析(第2報)

          李映弦,郭炳華 한국화훼연구회 1994 화훼연구 Vol.3 No.1

          Most of flower production in Korea today is for domestic comsumption. Flower production in Korea has increased almost 10% annually. While 3.5million dollars worth of flowers was exported from Korea, the annual amount of Korea flower imports has run up to approximately five times more than those of the export in the year of 1992. The objective of this report is to ascertain some potentiality of successful flori-cultural export from Korea in the future, through revealing and assessing the available statistics relevant to the world trade of flowers. 1.Due to the favourable environmental conditions for the production of bulbous ornamentals, today Holland has shared 73.3% of the world export. Holland is of a country which has developed high level of technology in the flower production, and also expanded production of flowers through cooperative plantation system in foreign countries such as Kenya and Zimbabwe, etc. These African countries have very suitable climate and low wage conditions for the cut flower production. Israel is also with naturally favourable climate of growing good quality of cut flowers during the cold season of EC countries. It is exporting carnations, chrysanthemums, statices and gypsophilas. It has also location advantage of short distance required only four-hour flying to EC countries. 2.With comparatively short distance of four-hour flying to the USA, Colombia is currently the next outstanding country in flower export. The species of flowers being exported, cut flowers of carnation, chrysanthemum and rose, etc., that are to be produced around the whole year. Approximately 70% of the total cut flowers being imported to the USA comes from Colombia. Colombia has advantage in the production under lower production costs owing to the favourable climatic conditions and low wage rate(i.e., $120 to 150 for a person per month work at farms ). 3.Noteworthy quantity of orchid "Denphalae" from Thailand is exporting to Japan. Orchids are the items of high price and very esthetic with its nature of sustaining good quality during the freight, and with high preference among Japanese people. In fact that cattleya orchid is imported from Singapore and cymbidium orchid from New Zealand into Japan imply that there may be some possibility of developing these items for exporting the commodity from Korea to Japan. In this regard, the production system in large size with locational specialization for joint operation is considered to be necessary in Korea today. 4.Japan can be considered to be new strategic export market for orchid cut flowers, because we have some advantage such as distance in the location and different growing season in contrast to New Zealand and Holland that are currently the largest cymbidium orchid exporting country to Japan.

        • 응급의료체계 활성화 방안 : 병원전단계 인적 자원을 중심으로 Focused on Manpower in Pre-hospital Emergency Care

          이영현 광주보건대학 2001 論文集 Vol.26 No.-

          The purpose of this study was to provide the basic data for improvement of EMS-System. The issue of training especially as it relates to Manpower in EMS-System delivery is more important than emergency medical equipment and facilities for pre-hospital emergency care. EMT-P can take care of the emergency patients following the order from medical Director at the scene of accident in american EMS-System. Hereby this study make the suggestion to develop the EMS-System, it is effective for EMT to applicate the same level as an american EMT-Plegally. The transport of emergency medical patients carried out almost by 119 Emergency Medical Service but out of all the emplyees at 119 EMS only 5.5% have own qualified EMT degree. They should be employed specially at 119 EMS to meet the growing needs for a superior level of emergency medical care for civilian.
