도시와 산업의 발달 및 인구의 도시 집중화로 다양한 종류의 오염물질이 다량으로 대기 중으로 배출되는 등 환경오염이 사회의 중요한 문제로 부각되고 있다. 특히 대기 중 10 $\mu\textrm{m}$ 이하의 미세입자들은 10~60 % 정도가 기도를 지나 폐까지 침투하여 폐포에 침착되기 때문에 인체에 해를 끼칠 수도 있다(Chow et al., 1996). 또한 월드컵 개최 1년여를 앞두고 환경부에서 차량 부제시행, 배출업소 가동율 조정등 대기오염 저감을 위한 대책의 시행효과, 문제점 등을 파악하여 대책을 보완하기 위해 5월 25일부터 6월 25일까지 1개월 동안 예행연습을 실시하였다.

Few patients with traumatic aortic laceration remain undiagnosed and survive long enough to develop a chronic aneurysm. Such aneurysms are frequently asymptomatic: alternatively, they may manifest chest pain, dysphagia, bronchial irritation, or sudden death. A case of aortobronchial fistula secondary to a chronic post-traumatic aneurysm of the aortic isthmus is presented. Hemoptysis was the main sign. The affected segment of the thoracic aorta was repaired with a Hemashield patch and a left upper lobectomy was performed.

In this paper, the overall contents of InJo's disease centering on the records from Chosun Dynasty's Official Records were examined. As a result, it was elucidated that the fundamental cause had lied in internal injuries of the Spleen and Stomach. The reason behind the constant change from fever to chills that agonized InJo the most lied not so much in external hazards as much in the injuries of the Spleen and Stomach. The treatment for InJo focused more on acupuncture methods than herbal medicine, which is thought to be characteristic of mid-Chosun Dynasty starting from the times of prior king SunJo or GwangHaeGun.

DC-Motor is needed more and more sophisticated control to follow the highest precision of industrial automation and used in a number of control equipment or industrial fields. It is also useful to control single crystal($Al_2O_3$) growth. It is possible to procure a quality crystal utilizing a DC-Motor, if you mix Hydrogen and Oxygen gas properly and keep proper temperature in accordance with time process. In this paper, we will study about electrical valve positioning system for the gas mixture to improve the quality of single crystal($Al_2O_3$) growth and we will design about realtime monitoring systems of the automatic gas contol DC- Motor for single crystal($Al_2O_3$) growth

These experiments were carried out to compared with components of AGM and raw beef. The results obtained were summarized as follows: 1) In proximate compositions of raw beef and AGM, water, protein, and fat were 71.21% and 48.47%, 29.35% and 21.85%, 5.36% and 14.95%, respectively. 2) Total amounts of amino acids of AGM were higher than raw beef, and glutamic acid was the highest in both, but methionine was the lowest in AGM, and cystine, in raw beef. 3) In fatty acids composition, unsaturated fatty acids were 90.4%, and linoleic acid (57.63%), among them, was the highest in AGM. But in raw beef, saturated fatty acids were 35.2%, and oleic acid, among them, was the highest content.

실크 피브로인은 천연 고분자 물질 중 하나로 Bombyx mori와 Antheraea perni 등이 있으며 생체적 합성을 가지고 있어 효소고정화를 위한 매트릭스나 세포배양용 지지체와 같은 의료용 분야에서 활발히 연구되고 있다. 또한 키토산은 키틴이 50% 이상 탈아세틸화된 것으로 갑각류, 곤충류, 균류 등에 존재하며 창상피복재, 인조 피부 등의 의료 분야에서 광범위하게 사용되고 있다. 본 실험에서는 실크 피브로인에 단독으로는 전기방사가 되지 않는 키토산을 다양한 비율로 블렌드하여 키토산이 실크 피브로인의 전기방사된 섬유의 형태에 미치는 영향에 대하여 알아보았다.

Surgical treatment is recommended in tricuspid valve endocarditis not responding to antibiotics or presenting severe heart failure. However, risk of early prosthetic valve endocarditis especially in drug addictors is principal concern in the treatment. A 37 year-old man with tricuspid valve endocarditis underwent staged operation of primary tricuspid valvulectomy and secondary bioprosthetic valve implantation successfully. We report it with references of literature.

다양한 오염원에서 배출된 오염물질은 가시광선 산란에 의한 시정악화 (visibility impairment), 산성 침착 (acidic deposition) 등과 같은 지역규모 (regional scale)의 대기오염문제와 오존층 파괴, 온실효과 등과 같은 지구규모 (global scale)의 대기오염문제를 야기 시켰으며, 더 나아가 인간의 건강과 복지에도 심각한 악영향을 미치고 있다. 이와 같은 문제는 환경에 대한 관심을 고조시켰으며 이러한 대기오염문제를 해결하기 위한 기술적, 경제적, 행정적 투자와 많은 연구들을 증대시키는 결과를 초래하였을 뿐만 아니라 대기오염 피해로 인한 건강 및 복지손실을 최소화하고 산업체의 경제적 손실을 최소화하기 위해 합리적인 각종 대기환경 관리기술이 도입되고 개발될 필요성 또한 대두되었다.

Possible methods of protection of non cellulosic fibers, particularly nylon filament yarn, from the damaging effects of light are discussed. Manganese acetate, cupricacetate, G1-06-196 and sodium phosphate are used as a light stabilizer for nylon filament yarn. The light stability of filament containing different weight of TiO$_2$ is increased as the following order: Bright>Semi-Dull>Full-Dull The protection effect against light according to the present of the light stabilizer in filament increased in the following order: Manganese acetate> Cupric acid> G1-06-196> Sodium phosphate Manganese acetate is shown to be the most effecting salt for protecting nylon against light. 15 ppm of the salt is shown to be effective enough for protecting nylon filament yarn against light.

In this paper, a new model error following sliding mode control is considered with a novel sliding surface for the error. This novel sliding surface has nominal dynamics of an original state of the error system and makes it possible that the Sliding Mode Control(SMC) technique for the error of the model following is used with the various types of controllers. Its design is based on the augmented system whose dynamics have a higher order than that of the original error system. The reaching phase is removed by using an initial virtual state which makes the initial error state sliding function equal to zero.
