Wilson’s disease is a rare, autosomal recessive inherited disorder characterized by excessive copper storage, particularly in the brain, liver, kidneys and cornea with resultant organ dysfunction. This was a case of Wilson's disease found in a 19 year old korean boy. 1) The patient showed progressive dementia, tremor, dysarthria and Kayser-Fleischer ring on the corneal margin of both eyes. 2) The laboratory findings showed low level of ceruloplamin(0.08㎎ / dl), serum copper (46ug/dl ) and high level of urinary copper(17l8ug / 24h) and henatic copper( 1184ug/gm dry weight). 3) D-penicillamine and low copper diet were given and we observed progressive clinical improvement.

This study has been carried out to investigate odor characteristics and removal methods on the water quality and sulfuric material of four urban sewage. The results from these experiments are as followings ; 1. For sediment, N contents(%) was shown 0.068mg/l at S-1, 0.109mg/l at S-2, 0.043mg/l at S-3, 1.233mg/l at S-4 and S contents(mg/g) was shown 2.192mg/l at S-1, 2.410mgA at S-2, 1.564mg/l at S-3, 15.146mg/l at S-4. The sample of S-4 was indicated the worst value to 1.233mg/l 2. NH₃, one of the representative odor materials, which was showed the highest value at S-1 in the water, showed the highest value at the S-4 in the air. It means that the cause of odor comes from the disintegration of sediment orgamisms, which has more important effect than the water pollution. 3. To control the odor materials, it is desirable to minimizes the inflow of sewage from pollutant source itself. One of the considering odor method is H₂O₂ or activated carbon input into the sewage, which has several advantages as chemical treatment of odor materials is to be desirable.
Incontinentia Pigmenti Achromians ( Ito ) : Report of two cases
조정구,김성운 대한피부과학회 1976 大韓皮膚科學會誌 Vol.14 No.1
Incontinentia pigmenti acb.romians(Ito) is characterized by progressive bizarre or whorl-like hypopigmentation on trunk and extrementies during childhood. It is similar to a negative picture of incontinentia pigmenti(Blocb-Sulzberger) and not infrequently associated with mental, bony and ocular defects. The incidence of this disease is predominent in femaIe without hereditary background. Case 1. Two years old female was visited to our clinic because of mottled depigmented patches on right thigh for about 8 months. Case 2. 14 months oId female was visited to our clinic because of linear and. mottled depigmented natches on their limbs for about 7 months. Histopathological findings of both cases shows the focal depigmentation on basal layer. They are treated with steroid ointment with moderate to good effects.

When we think of the reality of math education in the Korean high schools, there are many low aptitude students who have problems in teaming math due to the difficulties of the subject. Unfortunately, they are neglected due to their low academic abilities. A reluctance to learn, past experiences in math and a lack of interest due to an inappropriate loaming atmosphere are some of the reasons for this problem. Therefore it is most important to stimulate their interest in learning math to teach good learning habits and develop a good attitude towards math.
