  • 단감원에서 미국측 검역기준에 적합한 방제력을 개발하기 위하여 미국에서 이과류에 농약잔류허용 기준 (MRL)이 설정되어 있는 농약 (azoxystrobin, carbaryl, cyhexatin, fenarimol, mancozeb, methoxyfenozide, spinosad, trifluxistrobin)들을 중심으로 미국 수출형 방제력을 적용하여 단감 수확과에 잔류하는 농약 잔류량을 조사하였다. 적용 분석법에 의한 azoxystrobin과 carbaryl, cyhexatin, mancozeb, spinosad, trifluxistrobin은 검출되지 않았다. Fenarimol과 methoxyfenozide의 잔류량은 0.016-0.020 ppm과 0.022-0.029 ppm으로 미국의 이과류에서 잔류허용기준량 (fenarimol 0.1 ppm, methoxyfenozide 7.0 ppm)이하로 검출되었다. 본 연구에서 적용한 미국 수출형의 새로운 방제력으로도 미국측의 검역기준에 적합한 단감 재배가 가능하였지만 노린재류의 피해를 경감시킬 수 있는 방법의 보완이 추후 검토되어야 할 것으로 보인다.

  • This paper presents the design of a multiple beam optical tweezers instrument used for manipulating micro/nano-sized components. The basic equations used in designing the optical tweezers are derived and the stable and time-sharing multiple beam optical tweezers are constructed with scanning mirrors. The laser beam passes through a series of optical components such as lenses, mirrors, and scanning mirrors, and overfills the entrance aperture of microscope objective, which gives a stable trap. By rotating the laser beam with the scanning mirror, the focal positions are translated in the specimen plane and multiple micro/nano-sized objects can be moved. The constructed optical tweezers is used to manipulate cells and liposomes simultaneously and to trap multiple nano-wires. The experiments prove that the developed optical tweezers can be a very versatile manipulation tool for studying gene therapy and nano device fabrication.

  • The objective of this study is to propose an export strategy due to an analysis of USA and Japan consumer's perception and willingness-to-pay for flower tea. For that, we conducted a survey on the consumer's perception on flower tea compared with leaf tea such as green tea. We also analyzed the willingness to purchase and pay for it. The reasons of drinking of flower tea for USA consumer are 'flavor'-followed by 'taste', and for Japanese consumer 'relaxation'-followed by 'flavor' in order. Both of them consider 'quality', 'safety'- and 'origin' in order when they purchase flower tea. USA consumers have a willingness-to-pay of about 8.3% and Japanese consumers have a willingness-to-pay of about 29.1%. Based on those results, it is necessary to differentiate the process and marketing strategies for the export of flower tea.

  • This study concerns the demand for Korean textile products in the USA, Japan, EU from 2000 to 2003. The result from the practice of study is as follows; The grand total export demand of textile product is estimated about U$7.2billion in 2000, U$8.5billion in 2003, and the annual growing rate is estimated 5.17%. The export of textile product to USA, Japan, EU, and other countries will be gradually increased from 2000 to 2003. Comparing to annual average export growing ratio, it is expected the ranks of annual average growing ratio as follows; The highest ratio is 8.35% in EU, the next 7.08% in other countries, 2.67% in Japan, and 2.51% in USA. It shows the change of the new countries to which our nation exports textile-products from the exportmarket structure of the present major export countries such as USA, Japan to EU and other nations. Also shows the same result in the export ratio by countries. The research predicts that the textile export portion will be decreased for our nation to USA and Japan while increased to EU and other countries.

  • This study compared and analyzed with the United States(USA) to evaluated the level of readability of radiotherapy information (English text) provide to foreign patients with cancer by medical institutions in South Korea (KOR). A total of 20 the KOR and USA medical hospitals in 10 each provide information for radiation therapy technology were selected. The readability was comparatively analyzed a total of three aspects (lexical, syntactic, cohesion and readability) by using a Coh-Metrix on-line web program. In readability respect, the mean of the Flesch Reading Ease (FRE) was lower in the KOR (8.3) than in the USA (23.2), Flesch-Kincaid grade level (FKGL) was higher in the KOR than in the USA (14.2) indicating that KOR was less readable than the US (p<.05). In both KOR and USA, the reading level (literacy) of the English text for the radiation therapy was found to be higher than high school (FRE level 50 or lower). Therefore, text information in English for the radiation therapy to foreign patients with cancer should be lowered to elementary school level and read to improve the quality of medical services.

  • Cities cover only 3% of the planet's surface, yet they are responsible for more than 75% of the global emissions. Given the projected urban built area will double by 2060, the carbon emitted from cities will further increase. SOM proposes the Urban Sequoia concept, for buildings that go beyond 'net zero' and absorb carbon from the atmosphere. This concept combines multiple strategies, including the use of an optimised building form with a highly efficient structural system, modularized prefabrication techniques, holistic integration of facade, MEP and interiors' components, bio-based materials, and Direct Air Capture (DAC) technology, to reduce a 40-storey building's whole life cycle carbon emissions by more than 300% over a 100-year lifespan. Calculations of embodied carbon emissions are performed with SOM's in-house Environmental Analysis (EA) Tool to demonstrate the effectiveness of employing Urban Sequoia's design strategies in the design of new buildings using current technologies.

  • This study explored a terminal values of home economics students at Chonnam national university in Korea. And the terminal values of them were compared with those of USA and Japan. Through this, it make to explain the similarities and differences in terminal values among 3 nations. 175 students were adapted as data in Korea. Data of USA and Japan were obtained from Holyoak, Sawai, and Rauniyar(1993). The data were analyzed by frequency, percentage, means, one-way ANOVA, Duncan-test. The results showed significant similarities and differences in terminal values among 3 groups.
