화학용액 담금의 방법에 의하여 다결정 CdS박막을 성장시켰다. 성장과정에서 온도조건, 몰농도 조건에 따라 CdS 다결정의 특성에 영향을 주는 요인들을 전자현미경, 광흡수 및 광전류 특성과 온도 및 빛의 세기에 따른 저항의 변화를 통해 분석하였다. Polycristalline CdS thin films have been grown by the chemical bath pyrolysis(CBP) method. The CdS films characteristics were investigated with scanning electron microscope(SEM), optical absorption measurements, photoconductivity, and resistance dependences on temperature and light intensity.

Type-C retrovirus, human T-cell leukemia virus type-l(HTLV-1), has been shown to be associated etiologically with adult T-cell leukemia, which is an endemic disease in southwestern parts of Japan. We examined the seroepidemiological characteristics of antibody to adult T-cell leukemia virus associated antigen (anti-ATLA-antibody) by the indirect immunofluorescent assay and ELISA from the healthy individuals and various diseased patients in the Republic of Korea, a country adjacent to Japan in which HTLV-1 is endemic. The results were as follows. 24 out of 9,603 individuals(0.25%) were seropiositive. The positve rate was 0.17% in males and 0.36% in females, the sex difference was female predominent relatively. HTLV-1 carriers were found 16 individuals in Seoul, 5 in Kyonggi area, 1 in Chungnam and Jonbuk, respectively, but found only 1 individual in Busan city and Jaejoo area close to southwestern parts of Japan. Positive rate to anti-ATLA-antibody seemed to be high in older age, especially at the 50s(0. 4Yo). In conclusion the prevalence rate of anti-ATLA- antibody seemed to be very low in the Republic of Korea adjacent to Japan in which HTLV-1 is endemic and no patient with adult T-cell leukemia has been found as yet. Also we noted that the Republic of Korea is not an endemic area to HTLV-1.
