曺煥,李石榮,許萬宇,鄭元圭 嶺南大學校 工業技術硏究所 1983 연구보고 Vol.11 No.1

A study has been undertaken to know the reason why the white specks appear in the polyethylene terephthalate (PET) filament fabrics which were made alkali weight loss treatment in the dyeing and finishing factories of Taegu area. The results are as follows 1. Main component of the white spects in PET filament fabrics is CaCo₃. 2. The CaCO₃was extracted from the washing water and adhered to the PET filament fabrics during the dyeing and finishing process. 3. When PET filament fabrics were treated with hard water, the warp sizing agent did not dissolve to make specks on dyed fabrics. Then the insoluble sizing agent can not be got rid of by alkali treatment. 4. On account of using Na₂CO₃ in washing PET filament fabrics, white spects also can be appeared.

Human sparganosis is a rare infection caused by a tape worm larva, the genus Spirometra. Most infection occurs in the soft tissue, and sparganosis of the brain is very rare. There is no effective chemotherapy, and the best treatment for cerebral sparganosis is surgical removal of the worm, as in the case of the noncerebral form. A 40 year-old Korean man presented a 10 year history of episodic confusion followed by grand malseizure. He also had a history of consuming snake meat. Computed tomography and magnetic resonance imaging of the brain showed a lesion of the right temporoparietal lobe. Micro-ELISA test for sparganum specific antibody revealed high anitbody levels of absorbance 0.39 in serum, and 0.53 in cerebrospinal fluid. He refused operation, and a single maximal 50 Gy dose of irradiation by gamma knife was done. After 6 months, the lesion had no interval change on brain CT.

By suggesting the green city characterization measure for each region and zone that can lead the low carbon green city which is a new national vision in order to actively cope with the climate change, the global environment issue, we aim to seek for the measure to build up low carbon green city suitable for local characteristics. With low carbon green growth and environment protection by using abundant natural resources and various historical/cultural resources in Seo-gu Chungmu-dong and Nambumin-dong, the old downtown of Busan, the city reclamation measure can be prepared based on a new growth driving force and local economic vitalization. It is a general measure related to easing and adapting to climate change like water circulation, including setting up the three main goals like reclamation of residence on slopes, urban ports and business districts in old downtown based on green technology, and the six core strategies like establishing system of carbon reduction through using low carbon energy, improving the transportation structure through introducing green traffic system, having water/resource circulation system through low carbon circulation resource, having green construction system through applying green technology and environmentfriendly materials, building up ecotype greens based on the carbon absorption system through management of greens and urban forest and creating green community through private and public green partnership. It is possible to control microclimate by connecting wind ways, restoring ecology through using green infrastructure and producing its own energy based on environment-friendly technical elements as also suggesting residental models suitable for local characteristics based on the house project to improve obsolete residential facilities with low carbon green city leading project in Seo-gu. For the urban port reclamation, bio-energy is produced by building up biomass system through organic waste generated in the joint fish market. As also forming waterfront and green network connecting with Mt. Cheonma, it can be the representative low carbon green growth city in Busan.

In this study, examined the cutting characteristics of alumuminum alloy AC8A-T6 that is used to present car piston materials. And in been holding materials machining empirically escape as result that experiment comparison changing the cutting speed and feed on various condition to choose efficient machining condition. The following results can be summarized from this research. 1.As the cutting speed decreased, principal cutting force and thrust cutting force is increased, and reason that cutting force interacts greatly in the low cutting speed is thought by result by BUE's stabilization. 2.The feed speed and cutting speed increase, friction factor is decrescent and the cause appeared the thrust cutting force is fallen than cutting force relatively because chip flow according to increase of the feed rate is constraint. 3.Though specific cutting resistance grows cutting area and the feed rate are few, the cause was expose that shear angle decreases by rake face of tool gets into negative angle remarkably as wear of a cutting tool or defect part of workpiece is cut. 4.Cutting speed do greatly depth of cut is slow, surface roughness examined closely through an experiment that becomes bad, and know that it can get good surface that process cutting speed because do feed rate by 0.1㎜/rev low more than 250m/min to get good surface roughness can.

This study is designed to evaluate the clinical implications of Gd-DPTA (Gadolinium-diethyl - enetriamine pentacetic acid) enhanced MRI(Magnetic resonance imaging) in Bell's palsy and find it's usefulness in Oriental Medicine In this study, 25 outpatients with Bell's palsy were studied that MRI was performed. To evaluate degree of facial palsy, H-B(House-Brackmann) Grade was used. In Oriental Medical therapy, Acupuncture and Herbal medicine were treated. Subjective causes was divided into exposure to chill, fatigue, stress, mixed cases. Enhanced site was compared with symptoms which were disorder of eye, hearing, taste, and facial muscle palsy. Also, Relation between time which was performed MRI and enhancement was analyzed. The enhanced lesion in MRI was divided into five segments; Internal auditory canal, Labyrinthine segment, Geniculate ganglion, Tympanic segment, Mastoid segment. In Bell's palsy, 20 of 25 patients(80%) had abnormal contrast enhancement of the facial nerve. The H-B grade and interval performed MRI from onset were directly proportionate to enhancement. That is to say, Severe facial palsy short interval show high possibility of enhancement. There was no relation between subjective causes and enhanced site of facial nerve in MRI. Also Clinical symptoms didn't coincide with MRI findings.
