Scientific Publication Productivity of Korean Plastic Surgeons: An Analysis of 1974-2000 SCI Papers

The aims of this paper are to identify where the quality research activity has been and is carried out in Korea, and to examine weather the Korean plastic surgeons have sufficient capacity to place their official journal "The Journal of Korean Society of Plastic and Reconstructive Surgeons(KPRS)" to international databases. We investigated the publication productivity of all departments of plastic surgery in Korean medical colleges, hospitals, and clinics as measured by the number of papers in journals indexed in SCI(Science citation index). The 27 year period from 1974 to 2000 is covered. A total of 195 papers is published in SCI journals by the plastic surgeons in Korea. The first SCI paper was published in 1985; the number of publication has gradually increased. Since 1998, over 30 papers are annually published in SCI journals by Korean plastic surgeons. The production of SCI papers are concentrated in a few universities. About seventy percent of SCI journal papers is published by top seven medical schools; 25.6% by Yonsei university. In 1985, only one medical school was involved in the production of SCI journal papers. After 1997, however, more than 10 medical school and some surgeons in local clinics published SCI journal papers. The percent of SCI journal papers among all papers written by the Korean plastic surgeons increased recently: About 15% are published in SCI journals in 1999 and 2000 respectively. These data suggest that Korean plastic surgeons have enough capacity to place their official journal KPRS into international data bases.

Changes of Transient and Steady VEP by Checkboard Contrast

We measured the changes of each component of YEP by increase in contrast 8%, 30%, 60%, 90%, 98% in small checkerboard pattern stimuli and large checkerboard pattern stimuli in 10 normal subjects (20 eyes) in order to get basic data for utilizing YEP according to changes of contrast in clinical diseases group, N1 latency and P1 latency were notably shortened from 30% to 60%. N2 latency was extremely shortened from 60% to 90%. N1-P1 amplitude and P1-N2 amplitude were remarkably increased from 30% to 60%. The amplitude of steady YEP generally increased as the contrast was increased. Immatured YEP wave was turned to matured YEP wave between contrast 30% and 60%. Threfore, when we apply YEP with to lower contrast of stimuli clinical cases, the appropriate range of contrast is from 30% to 60%.

Variability and application of VEP components in Transient VEP and Steady VEP

Before VEP use in clinics, we studied in statistical significance between borh eyes, intrasubject varciabilty intersubject variability (between incdividul) and changes of VEP cmponents between ignorance and attention in losujects (20eyes). There was no statistically significant difference between both eyes in each component of VEP and the variability of intersubjects was larger than that of intrasubjects. The smallest variability of intersubject was N1, P1 latency and that of intrasubject was PI latency in each component of VEP. When subjects were ignored, N1-P1, P1-N2 and steady VEP amplitude decreased significantly but N1, P1 and N2 latency were no significant difference.

Changes in ERG b-wave and Oscillatory Potential in Relation to the Dark Adaptation and Light Adaptation Time

Authors studied characteristics of ERG b-wave and oscillatory potential, which can be applied to ERG protocol for clinical purposes. Following conclusions were obtained from the ERG test performed on 20 normal men(40 eyes) during dark adaptation and light adaptation time, under the conditions where other factors were equal. 1. In the scotopic ERG test, 88%(364/414uv) of maximum b-wave amplitude in 30 minutes were obtained in first 1 minute of dark adaptation. By using this shortening scotopic protocol for the acquired retinal disease, sufficient result can be expected without the over 20 minutes dark adaptation. 2. In the photopic ERG test, if over 30 minutes dark adaptation time were given, it would take at least 15 minutes to reach the regular initial photopic value. Therefore, it is recommended that photopic ERG test be done before the scotopic ERG test. 3. In the oscillatory potential test, light adaptation time has little effect on summed photopic oscillatory potential amplitudes and implicit time. Summed scoto pic oscillatory potential amplitude reaches the highest 1 minute after the dark adaptation. Therefore, it is recommended that to obtain higher amplitude and more sensitive test result, oscillatory potential test be done 1 minute after the dark adaptation.

Clinical Study of Scabies and Itch Mite / 대한피부과학회지

The clinical and biological study for Sarcoptes scabiei from 66 scabies patients was performed form Nov. 1974 to April 1975. The diagnosis of these scabies patients were confirmed by method proposed by Muller et al. The results were as follows; 1) Male to female ratio is 5. 6: 1 in total patients and predominant age group is in 16~20 in both sexes(Table 1). 2) 50% of cases had family history of similar troubles and the duration of subjective symptom complaind at their first visit was 1~2 weeks in 20 cases, 3~4 weeks in 25, 2 months in 10, and over 3 months and unknown were 12. 3) Suspected sources of infestation were, 22 cases from one of their family members, 15 at hotel, 7 at boarding house, 2 at camping, 1 at military camp, 19 were unknown. 4) Distribution of burrows was hand(79.4%), wrist(12.4%), foot(3.1%), penis(2.6%) scrotum(2.1%) and axillary area(0.5%). Number of burrows was 1~2 in 61.4%, 3~4 in 19.3%, 5~6 in 5.3%, 7~8 in 1.8%, 9~10 in 5.3% and 10 in 7. 6%. 5) 44 patients (66.7%) were confirmed by finding of female mite and among them 50% had 1 female mite, 36.7% had 2, 6.8% had 3, 2.3% had 4 and 4.5% had 6. 6) 69 among total 79 female mites detected were found at burrow, 6 from papule and 4 from vesicle. Total 7 male mites were found from patients and 4 from papules and 2 from veside and 1 from pustule(Table 5) 7) From total 194 burrows examined 69 female mites (36.1%) were found and non of male mite were found. 8) Mean size of female mite(length*breadth) was 359.3u*266.5u, male mite 21.1u*160.9u, larva 131.8ux94.2u, egg with developing larva 167.3*93.6u, egg with developed larva 159.7u * 92.3u and scybala 18.7u x 12.3u. Sizes of egg with developing larva and egg with developed larva had no significant difference, statistically.
