  • We present a process for printing active matrix displays. In this process, transistors are fabricated using soluble semi-conducting and conducting materials. Accurate definition of the transistor channel and other circuit components is achieved by direct inkjet printing combined with surface energy patterning. We present results on our 4,800 pixel, 50 dpi, active matrix displays.

  • We have developed 3-stage of Magnetic Switch System based on the nonlinearities of ferromagnetic material used in the saturable inductor, and made experiment of parameter optimization and output stabilization of Magnetic Switch System. The cross-section and conductor burns of each satarable inductor were optimized 30 $cm^2$ 19.25 $cm^2$ 5, and 25 $cm^2$ 2, respectively. With this condition, 6.2 us [FWHM], 96 A pulse at first stage was compressed into 0.4 us[FWHM], 1.61 kA pulse at last stage. The current gain and compression ratio were 16.8, 17, respectively. ln addition, System output was stabilized with reset current of 6 A, 200 us.

  • We studied the meaning of the term avant-garde in relation to clothing of the 1980s and 1990s by examining the media's perceptions of Martin Margiela, a Belgian deconstructionist designer who was often labeled as avant-garde by journalists, scholars, and fashion critics in the late 20th century. A five-step content analysis method described by Paoletti (1982) was used to conduct the research. Newspaper and magazine articles in the 1980s and 1990s were analyzed using a set of existing avant-garde characteristics developed by Crane (1987) to determine if those journalists' perceptions matched the characteristics described by Crane. Results indicated that the journalists' critiques and descriptions matched the avant-garde characteristics described by Crane (1987). Including a subjective element to the conceptualization of the term explains how journalists described Margiela's designs despite Japanese designers' use of similar techniques before him. We (re) conceptualize the term's latter 20th century meaning and shifting dialogue to include a subjective element.

  • The use of ionizing radiation and radioactive elements is becoming increasingly popular with the rapid developments in nuclear technology, radiotherapy, and radio diagnostic methods. However, ionizing radiation can directly or indirectly cause life-threatening complications such as cancer, radiation burns, and impaired immunity. Environmental contamination with radioactive elements and the depletion of ozone layer also contribute to the increased levels of radiation exposure. Radioprotective natural products have particularly received attention for their potential usefulness in counteracting radiation-induced damage because of their reduced toxicity compared with most drugs currently in use. Moreover, radioprotective substances are used as ingredients in cosmetic formulations in order to provide protection against ultraviolet radiation. Over the past few decades, the exploration of marine algae has revealed the presence of radioprotective phytochemicals, such as phlorotannins, polysaccharides, carotenoids and other compounds. With their promising radioprotective effects, marine algae could be a future source for discovering potential radioprotective substances for development as useful in therapeutics.

  • An Experimental study on the NOx formation of LNG flame in fuel staged combustor has been studied. The design concept of multi fuel/air staged combustor is creation of two separate flame, a primary flame is act as a pilot flame for the secondary combustion stage combustion zone, where most of fuel burns. Experiments were performed on a semi-industrial scale (thermal input 0.233 MW) in a laboratory furnace and Liquefied Natural Gas(LNG) was used as primary and secondary fuels. The study included parametric study to identify the optimum operating conditions which are primary/secondary fuel ratio, and primary/secondary air ratio for reducing NOx emission with two types of nozzle. The test demonstrated that NOx emission can be reduced by >70% in accordance with operating conditions.

  • Sanguisorbae Radix has hemostatic, analgesic and astrigent properties and it has been used for the treatment of burns, scalds and internal hemorrhage. Ziyuglycoside I was isolated from Sanguisorbae Radix and identified by the spectroscopic methods. In order to evaluate the quality of it, quantitative determination of Ziyuglycoside I in Sanguisorbae Radix using HPLC method has been conducted. Quantitative analysis of Ziyuglycoside I showed average 3.005% in 30 samples collected throughout the regions of Korea.

  • This study is aimed to improve safety of ladle in the metal products manufacturing industry. Burns may occur from spills, spatters or eruptions of hot metal from ladles during pouring or transporting. According to the statistics of occupational accidents about the ladle, many victims were exposed to or contacted with extreme temperatures. The many fatal injuries occurred as a result of unexpected discharging of molten metal due to tipping over ladles. To prevent ladles from turning over, the trunnion axis shall be located below the center of gravity of the ladle at all operating condition. For this purpose, the equation is proposed to calculate the minimum location of a trunnion axis for definite static stability when tilting.

  • 최근 병원 간 경쟁이 격화되고 의료시장의 개방이 임박하면서 많은 병원들이 경쟁력강화를 위한 전략 수립에 많은 노력을 기울이고 있다. 일반적으로 서비스산업의 경영에 있어서 고객의 요구를 파악하고 이를 경영관리에 반영하는 것은 중요한 경쟁력강화 전략의 하나로 인식되고 있다. 특히 의료서비스에 있어서 환자 만족은 소비자 선택에 직접적인 영향을 미치고 있는 것으로 나타나고 있다(Burns, 1994). 최근 강조되고 있는 환자중심의 병원도 병원을 찾는 환자를 의료소비자 개념의 고객으로 보고 그들을 만족시킬 수 있도록 의료 기술적, 인간 관계적, 서비스 편의적 노력을 다해야 한다는 의미를 내포하고 있다. 병원에서의 환자만족 향상 노력은 그 자체가 매우 다차원적인(multidimensional) 개념으로 양질의 의료서비스를 통한 삶의 질 향상과 환자들에게 병원에 대한 좋은 이미지를 심어줌으로써 충성도를 높이고자 하는데 그 목적이 있다.

  • The effects of various drugs on the alleviation of the symptoms of chemical bums were evaluated in mice to formulate topical antiblister preparations. After a chemical bum was induced on the mouse dorsal skin with 2-chloroethylethyl sulfide, the drug was applied on the disease site. The effectiveness of the drug was evaluated by determining blister size, necrosis score of skin and appearance of the chemical burns induced. It showed that steroids and aminoglycoside antibiotics had a tendency to protect skin cell, and antihistamines decreased the size of chemical bums. While oleaginous base resulted in deleterious effect, hydrophilic base didn't show a significant difference on the alleviation of the chemical burn symptoms compared to the control.

  • Burns can be caused by fire, chemicals, heated object and fluids. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. Algin is known as natural polymer marine plants, we prepared the official burn ointment which is made by Algin. This burn ointment was covered on the skin wound of artificial burned and their effect of healing was investigated by the evaluation of histological and hematological change as a function of time. The result of rats test showed that burn ointments made from Algin was effective in formation of the new tissue and reduction of inflammation.
