The onprovement of civil registration reguires continuous study rather than periodic efforts. More and better statistics, however, are urgently required to formulate development programs and planning, Data obtainable from the civil registration are usually marred by errors of omission which are difficult to correct. This study aimed at finding out the problems occurring when a set of crude birth registration data in a rural area is used. Data Sources of this study are : 1) For birth registration : government birth registration records obtained from myun office and other government offices. 2) for the actual number of births : birth and child records from the Kang Wha Community Health Project. The study area is Sunwon Myun and Naega Myun in Kang Wha Gun, Gyunggido. The reference period for the accumulated data is one full year : Jan. 1st 1975 - Dec. 31st 1975. Major findings are as follows : If the number of registered birth is compared with the actual number of births which occurred in the target area, the former os far greater than the latter. The general assumption usually is , that the actual number of exceeds the registered number of birth in Korea. The observation from this specific study in this specific target area, shows the opposite trend. The number of births which actually occurred during the year of 1975 in the study area namely 256. The difference comes mainly from the fact that many cases of births from other areas were registered in the target area. In other words birth is not registered where it occurred but where the permanent residence address is. Among 550 births registered in the target area 66% did not occur in the target area. Only one third of all registered births were registered within the legal period for birth registration which is 2 weeks. 34% of the registered births actually occurred in 1974, but were registered in 1975. In 55% of the cases a difference was observed between the actual data of birth and the registered data of birth. From the 256 births which occurred in the target area, only 153 births (59%) were registered at the myun office and the remaining 130 births (41%) were not resistered there in the year of study. 6% of the 550 cases listed as registered have no separate registration sheets. Nevertheless, they definitely have been registered in the birth list at the myun office. 3% of the 550 cases are not recorded in this list but have a separate registration sheet at the myun offices. In conclusion, birth registration data have many errors and problems. Their usefulness as a source for vital and other statistics should be reconsidered. A series of sound methological studies will be necessary to establish their actual usefulness. A continuous and permanent compulsory system of birth recording is needed.

Multiple myeloma is considered to be the most common primary malignant bone tumor which has the flat bone as a predilection site in old ages. We experienced a case of an unsual multiple myeloma which formed a huge tumor mass on medial end of left clavicle. The tumor mass together with medial half of the clavicle was excised completely. We have discussed the rationale for the excision of the clavicle.

The distribution of transforming growth factor-α (TGF-α) and epidermal growth factor (EGF) in developing mouse embryos of gestational age 8 to 15 days was immunohistochemically (ABC method) studied to investigate the differential expression of these growth factors. Paraffin embedded sections were immunostained with antibodies for TGF-α and EGF. Staining of TGF-α was observed in several organs derived from endoderm, mesoderm and ectoderm in 9-day-old mouse embryos, such as in the heart, optic pit, head mesenchyme, neural tube and primitive gut, and the staining became more intense in 10 to 15-day-old mouse embryos. The staining of EGF was seen in the heart and primitive gut derived from mesoderm and ectoderm respectively, in 9-day-old mouse embryos, but it was observed in other organs as well in 10 to 15-day-old embryos although the intensity was weaker. In the development of heart, immunoreactivity for TGF-α was more intense than EGF, which suggests more active involvement of TGF-α. In the lung, TGF-α staining was observed both in the bronchus and lung bud, whereas EGF staining was seen only the bronchus. In the nervous system, TGF-α was expressed more extensively and more intensively than EGF. In the developing skeletal system, TGF-α staining was stronger and the expression was observed at earlier stage compared with EGF. These results indicate that the activity of TGF-α is more potent than EGF in the development of mouse embryo in general, especially, in the development of mouse heart, nervous system, mesenchyme and skeletal system.

We report a case of woolly hair. Woolly hair is found frequently in most blacks but is unusual in individuals of non-negroid origin. A 12-year-old female patient visited our clinic complaining of a hair abnormality. It had been tightly curled, fine, light brown, short and easily broken since birth. On scanning electron microscopy, many of the hairs showed damaged cuticles with cuticular splintering, and most hair shafts were round to oval on cross sectional examination.
