Wire breakage in drawing, which is the most critical process in glass fiber manufacturing, is caused by numerous factors such as height, drawing speed, and air flow. The vibrations of the draw tower, however, is the most dominant factor to create the wire breakage. In this study, the structure of a draw tower has been analyzed through experiments and computer simulations to figure out the main reasons of the vibrations. And the design alterations were applied to the machine to identify the effects of those alterations. The result shows that design alterations of the draw tower structure can suppress the 87% of the vibrations, and further can prevent the wire breakage.

최근, 세계 각국은 전자정부 구현수준 고도화에 따른 공급자 측면의 구현단계를 지나 시민참여를 확대하는 단계로 진입하고 있다. 우리나라는 스마 트폰 3,000만대 시대를 넘어 누구라도 ‘언제’, ‘어 디서나’ 필요한 정보를 습득할 수 있도록 패러다임 이 변화하고 있으며 특히 영리․비영리 측면에서 공공정보 활용을 위해 공공정보 개방을 요구하는 민간의 수요가 급증하고 있는 실정이다. 공공정보 개방은 국가 기관이 보유․관리하고 있는 정보(콘텐츠, 부호, 문자, 음성 및 영상 등 모든 종류의 자료 또는 지식)를 민간이 활용할 수 있도록 공개․제공 하는 것으로 이를 통해 다양 한 서비스 개발 및 신규 비즈니스 기회를 창출함 은 물론 국민의 삶의 질 향상과 더불어 국가 발전 에 지대한 영향을 미칠 수 있다. 이러한 시대적 흐름에 발맞추어 공공기관은 보유 정보의 제공을 위해 역할 및 대응방안을 사전에 적절히 수립하 고 효율적이며 체계적인 제공체계를 마련해야 할 때이다.

이일환,노승훈,남규동,강신원,김영조,김건형 한국반도체디스플레이기술학회 2017 반도체디스플레이기술학회지 Vol.16 No.1

Semiconductor is one of the most internationally competitive areas among domestic industries, the major concern of which is the stability of the wafer manufacturing processes. The first process for the manufacturing of the semiconductor wafers is the ingot growing. The vibrations are supposed to be the most important factors for the ingot quality. In order to maintain the ingot quality, the growers have the automatic shut-down equipments which are activated by vibrations, and are sensitive enough to react to the earthquakes generated in Japan. In this study, the structure of an ingot grower was analyzed through experiments and computer simulations, and further the effects of design alterations to suppress the vibrations have been investigated. The final result shows that the vibrations can be reduced substantially to improve the stability of the structure.

Background : Monoplegia is the paralysis of a limb. It is commonly caused by an injury to the cerebral cortex, and rarely caused by injury to the internal capsule, brain stem, or spinal cord. Most problems with cerebral cortex is derived from the occlusion of a brain cortex blood vessel due to thrombus or embolus. Objectives : This study is to see if there is a significance in thermal differences of acupoints in diagnosis and treatment of monoplegia on an upper extremity to test the validity of acupuncture and herbal treatment for it. Methods : By using Digital Infrared Thermographic Imaging(DITI), thermal differences$({\Delta}T)$ of acupoints on the upper extremity in a patient with monoplegia on the right upper extremity were measured after an attack of the disease. By giving Mangeum-tang(萬金湯) and treating the patient with acupuncture. the temperature changes of the upper extremity were examined through DITI and improvement was observed. Results : Compared with the left arm which suffered no such injury, the right recovered about 80% of sensation, and the grade of monoplegia improved from Grade O to Grade V. Also, the temperatures of right palmar-dorsal hand and the region of Weiguan(外關, Waiguan, TE5) were $1^{\circ}C$ and $1.45^{\circ}C$ higher than the same left region on admission day, but the thermal differences$({\Delta}T)$ narrowed to $0.5^{\circ}C$ by the last day. Conclusions : Results suggest that DITI screening is a reliable method of prognosis and that the time required for treatment can be estimated through this method in cases of monoplegia to an upper extremity. Also, progress in treatment is reflected in thermal differences of acupoints of the monoplegic upper extremity in accordance with the theory of meridian. This supports a role for acupuncture and herbal treatment for monoplegia.

Hyperlipidemia is one of the major factors causing the atherosclerosis of coronary arteries and well-documented modifiable risk factors of stroke, especially of the ischemic type. For Insulin-Dependent Diabetes Mellitus sufferers, if blood sugar is appropriately maintained, lipid and lipoprotein are normal, but if blood sugar is inappropriately maintained or clinical Diabetic nephropathy induces metabolic disorder of lipid, then Total cholesterol, low density lipoprotein cholesterol, triglyceride and very low density lipoprotein cholesterol levels go up and high density lipoprotein levels go down. The purpose of this study is to evaluate the effect of treatment with Ojeok-san and to observe the changes in Fasting Blood Sugar(FBS), 2 Hours Postprandial Blood Sugar(PP2h), Haemoglobin A1c(HbA1c), Total Cholesterol(T-Chol) and Triglyceride(TG). After the treatment, Fasting Blood Sugar decreased from 149mg/dl to 89mg/dl. 2 Hours Postprandial Blood Sugar decreased from l85mg/dl to 110mg/dl. Haemoglobin A1c decreased from 6.3% to 5.7%. Total Cholesterol decreased from 268mg/dl to 217mg/dl. And Triglyceride decreased from 438mg/dl to 265mg/dl. These results support a role for oriental medical therapy in treating Diabetic Hyperlipidemia. Further case studies of herbal treatment of this ailment are needed.
