본 연구는 원통형 종이포트 토마토 육묘시 Diniconazole의 처리방법이 도장억제 및 근권발달에 미치는 영향을 검토하기 위하여 수행되었다. 그 결과, 엽면적, LAR, 초장, 충실도, 생체중, RGR 및 R/S 에서 시험구간 유의한 차이를 보였다. 동일한 농도를 처리했을 경우, 근권부와 지상부의 흡수도 차이로 인해 저면관수가 엽면살포에 비해 도장억제에 효과적이었다. 저면관수는 엽면시비의 10분의 1의 농도만으로도, 20~30%정도의 동일한 도장억제 효과를 얻을 수 있었다. 디니코나졸 처리에의한 근권부 반응이 흥미로웠는데, 저면관수시 총근장, 근권부피, 평균 근경 및 근단수가 증가하였다. 특히, 0.3mm 이하의 초미세근이 감소하고 0.3~0.6mm의 세근이 증가하였다. 따라서 원통형 종이포트 육묘시 저면관수를 하는 것이 기존 엽면시비에 비해 사용량이 적으면서도 도장억제 및 근권부 활착률을 높힐 수 있을 것으로 판단된다.

The University is to be established as an independent institution, with an appropriate status under the law of Korea. It will require such arrangements, incentives privileges and immunities as will facilitate the recruitment of international staff and the participation of faculty and students from all over the world. The University must be fully autonomous to ensure its intellectual and academic integrity and freedom from ideological constraints. The relationship with United Nations can be achieved without making the University an actual UN organization, through cooperation with UN agencies and organizations and participation of UN personnel in its faculty and programs. The core program centered at the University itself would be developed initially on the basis of the comparative advantage offered by its location in Jeju and the quality of faculty, full and part time, that could be recruited to the University. To reflect the complexity and range of issues in the field of sustainable development, it is planned that the academic program of the University should be organized from two mutually reinforcing perspectives, core competences underlying the whole program and specific areas of concentration.

Fly ash consists of various metal oxides which can remove SO2 gas by the catalyst effect. When fly ash is added in the preparation process of pitch-based activated carbon, the pitch particles aggregate and fly ash is embedded in the activated carbon. To increase SO2 gas removal performance, activated carbon was prepared by surface-treated fly ash and petroleum-based pitch. Carboxyl groups were introduced into the fly ash by malic acid treatment. The introduced carboxyl groups acted as an activation agent to create micropore around the fly ash, and created micropores were exposed to the fly ash outside of the activated carbon. The exposed fly ash increased removal amount of SO2 gas by a catalytic effect of the metal oxides. The SO2 gas removal performance improved by 34% because of the catalyst effect of the exposed fly ash and improvement in the micropore structure in the activated carbon.

In the automotive industry, the platinum titanium anodes (Pt/Ti anode) play a significant role in electroplating of chromium coating on the vehicle’s shock absorber piston rod. In this paper, the structure of Pt/Ti anode was designed to obtain high quality and save time for the electroplating process. The structure of anode was designed in 2D & 3D modeling and analyzed by CATIA and ABAQUS program, respectively. The structural modeling of the anode was analyzed and carried out using a finite element method (FEM) by applied various loads. The manufacture anodes were installed in an electroplating bath in order to test the efficiency of chromium coating on shock absorber piston rod and safety of anode structure. The results presented indicate that the structural analysis is safe after applied loads due to the allowable stress is higher than the maximum equivalent stress about 4 times, and the chromium coating test obtained high-efficiency results.

Defects in most structures can be generated not only on outside but also on inside or on the back-side during the manufacturing or construction process. Also they cause the growth of defects due to operation of various complex environments and structures will be destroyed eventually. In order to improve the reliability of the structure, the detection and size-estimation of defects should be investigated. In this paper, as an extension of previous studies on surface defects, two-dimensional artificial backside cracks (blind cracks) into paramagnetic material were evaluated by using the same aluminum probe. The potential drop at the defect position is distributed in the n-shape in the case of the back defect, which is different from results of the surface defect (u-shape). The potential drops at the defect position are measured with the largest value. The potential drop ratio (Vcmax/Vs) for the defective position is used as a parameter to predict the thickness (l) of defect position.

The University will contribute, through its high quality of education, training and research, to the containment, reduction and management of the problems confronting humanity in the transition to sustainable way of life utilizing the latest technologies of distance learning. Through international collaboration and leadership, it will generate, mobilize and share knowledge, experience and skills throughout the world so as to promote equitable and sustainable progress and to preserve and enhance the natural world on which humanity depends. As merit of the location of center in Northeastern Asia and North and South countries, Jeju Island has a remarkable natural beauty matching with unique environmental culture tradition, and a wide range of expertise, connections and capabilities in regard to global commerce, finance and transportation, and to the management of watersheds and biodiversity as a newly established international free city, all of which are relevant to world environment of sustainable development.

The name of the University. While there is a close relationship between the environment and peace, this should be reflected in the establishment of an institute or program rather that in the name of the University which should be, as originally conceived, the World Environment University. The credibility of the University will depend on the involvement in it from the beginning of highly influential leaders of the world environment movement. There is no better way of ensuring this than to obtain the formal involvement of IUCN which has in its membership most of the leading nongovernmental and governmental organizations of the environment and conservation movement

The kidney is a highly complex organ, and acute or chronic renal diseases can occur with various complications such as diabetes and hypertension. So far, no target specific treatment is available in acute or chronic renal failure, necessitating the development of alternative therapeutic strategy. Recent experimental findings suggest that the renal function and structure can be restored after being treated with various sources of stem/progenitor cells. In this review, we discuss up-to-date findings of the potential of renal progenitor/stem cells in alleviating renal injuries with a focus on preclinical studies. We also review cellular mechanisms underlying the therapeutic function of these cells.

Most structures require high reliability to ensure safety and soundness. The materials used for these structures are not only defective in the manufacturing process and construction process, but also cause generation and progress of defects due to operation of various complex use environments. In order to improve the reliability of the structure, it is very important to detect and estimate the defect size. The method of evaluating these defects without damaging the structure is a non-destructive method. In this paper, an aluminum probe of AC potential drop(ACPD) method is applied to the evaluation of two-dimensional artificial defects in ferromagnetic materials. Since the potential drop of the defect end is larger than that of the sound area, the defect can be detected and its position can be clearly confirmed, and the potential drops are changed according to the depth of the defect. The potential drop ratio (Vjmax/Vs) of the defective area has a large value for the defect. The relationship between the potential drop ratio (Vjmax/Vs) of 10 kHz and the defect depth can reduce the error in predicting the depth.

We want to have an opportunity to learn in a global context why GAN is so important to Jeju as Korea's largest Island in a multi-cultural society. Politically, Jeju Island succeeds have to survive ordeal from Jeju 4.3 Grand Tragedy. Geologically, as Jeju Island is located at center of East Asia, it has benefits from easy access to main cities to the island such as Beijing, Shanghai, Tokyo, Osaka, Seoul, Busan, Hong Kong, Taipei and so on. Environmentally, as Jeju was designated UNESCO Biosphere, World Natural Heritage and Geo parks, we want to keep it as a longevity island. Culturally, as we recognize it as a specialized in Western countries by human peace, Jeju as a World Peace Island tries to integrate aging human life agenda into part of a human life one. As the result, we suggest “Korea Care into Global Humanity in the Asia Pacific Context” as integrated policy agenda of both Korea and Peace Island villages for the 2021 GAN Biennial Conference from September 26 to 30, 2021 in Jeju Island Korea. As it based on village healing by villagers, Jeju island is small, as there is slrong soldarity between, we believe it can revive Korea communities.
