부상부유법에 의한 탈묵공정에서 계면활성제의 영향에 관한 연구
손종석,임종주,장연수 동국대학교 산업기술연구원 1998 산업기술논문집 Vol.12 No.-
부상부유법에 의한 탈묵 공정 중 계면활성제와 효소가 탈묵 효율에 미치는 영향을 알아보기 위해 본 실험을 수행하였다. 다양한 종류의 EO/PO 고급 알코올계 계면활성제와 NPE type의 계면활성제를 단독 또는 혼합하여 사용하였으며 세 가지 다른 종류의 효소인 cellulase, amylase, protease를 사용하였다. EO/PO 고급 알코올계 계면활성제와 NP type의 계면활성제를 혼합하여 사용할 경우 탈묵 효율은 계면활성제를 단독으로 사용한 경우와 비교하여 증가하였다. 혼합 계면 활성제 시스템에 cellulase를 첨가하였을 때 탈묵 효율은 소폭 증가하였으나, 백색도는 감소하였고, 인장 강도는 거의 변화가 없었다. Flotation deinking experiments were conducted in order to understand the effects of surfactant and enzyme on deinking efficiency. Various kinds of surfactants such as high alcohol EO/PO copolymers, nonyphenol ethoxylates or mixtures of both were used during this study. Also three different types of enzymes such as cellulase, amylase, and protease were added. When both types of surfactants were used during deinking experiments, removal efficiency was found to be increased. When cellulase was added to the surfactant mixture systems, it was observed that deinking efficiency was a little improved but brightness was decreased. The tensile strength was found to remain almost constant even with the addition of cellulase enzyme.

The purpose of this study was to report a case of an insomnia patient treated with a traditional Korean medical treatment. The patient had suffered from insomnia for 4 months and had taken medicines such as Zolpidem. We diagnosed the patient as So-yang-in, according to the Sa-sang constitutional medicine. We prescribed medicine with herbs for So-yang-in and applied acupuncture for 9 days, and then we evaluated sleep time, quality, and awakening, based on the patient’s statement. The symptoms of insomnia were gradually improved during treatment. Therefore, traditional Korean medical treatment can help insomnia patients sleep well without Zolpidem.

본 연구는 외국제품과 동등 또는 이상의 품질을 가진 고효율성 수처리 필터의 제조와 그 공정을 개발하는데 목적이있다. 개발된 필터의 여과효율은 93~99%로 기존의 국내산 82~97.5%, 일본산 92.5~98% 보다 우수하거나 유사하였다. 오염 입자의 양에 따른 압력손실(내구성)은 기존의 국내산보다는 현저하게 작았으며 일본산과 비교해도 약 0.1 kgf /cm2 의 낮은 압력 손실을 나타내었다. 또한 본 연구에서 개발된 카트리지 필터는 일본산 제품에 비하여 약 50%의 가격으로 생산이 가능하므로 기존의 국내산 제품뿐 아니라 일본산 제품에 대한 수입대체 효과도 기대할 수 있다. The purpose of this work is to manufacture of high efficiency water-treatment filter that is equal to imported products or even higher in terms of quality and even develop the manufacturing process. The filtration efficiency of the developed filter was 93~99%, which was better or similar to that of domestic filter (82~97.5%) and Japanese filter (92.5~98%). The pressure loss(durability) along with the amount of contaminant particles was significantly smaller than that of domestic products, and showed 0.1 kgf /cm2 less than that of Japanese products. In addition, at the cost side of production, the developed cartridge filter can be produced with 50% of the current price compared to that of Japanese products. Therefore, it is possible to replace the imported Japanese products as well as domestic products.

This patient was 18 year-old man who had severe nausea, vomiting, stomachache but medical examination revealed no abnormality. The symptom lasted for 2 months and he lost 15kilograms. The patient had no underlying diseases. He was treated by korean medicine, containing acupuncture, cupping therapy and herb medicines during 9 days. The severity of nausea was scored by the Numerous Rating Scale and the frequency of vomitng was evaluated by count. After that period, patient's symptom was improved and his other conditions were also better, compared with his admission. This study suggests that Korean medicine could have a therapeutic effect for nausea, vomiting, stomachache and rapid weight loss that the cause has not been diagnosed by Western medicine. It could help to improve patient's symptoms and make general conditions better.

Objective: To report a case of a patient with a psychosomatic disorder who complained of hyperventilation and was treated with oriental medical treatments and emotional freedom techniques (EFTs). Methods: The patient was diagnosed as having a psychosomatic disorder through an interview and several psychological tests, such as the house-tree-person (HTP) and the person in the rain (PITR) tests. We treated the patient with oriental medical treatments that included herbal medications, western medications, moxibustion, cupping, and EFT. Results: After the treatments, the clinical symptoms of the patient were improved. Conclusions: Oriental medical treatments and EFT may be effective treatments for psychosomatic disorders.
