To understand the current status of pediatric surgical practice of the members of the Korean Association of Pediatric Surgeons, a survey of the practice of the 31 members in both 1994 and 1995. Twenty five members(80%) representing 20 hospitals responded. An average of four hundred and seventy four cases pediatric surgical operations were performed at individual institution in 1995 with 40 newborn cases. Eighteen members(72%) are currently working at university hospital. Fourteen institutions(70%) are currently classified as tertiary by the health insurance agency. The majority(15 to 60%) of members are working in the metropolitan Seoul area, while five in Taegu area. Sixteen members reported having the title of department head/director. Four members reported occasional non-pediatric surgical practice. Nine members out of 20 reported having independent pediatric surgical out-patient clinic before the establishment of the association(1985). Eight out of 15 members reported being appointed chief of pediatric surgery before 1985. In 20 institutions, 34 full time physicians(27 members, reportedly) are working in pediatric surgery. In regarding to pediatric surgical training, 16 members(64%) received an average of 16 months of training abroad, 5 members trained at home and abroad, and 4 from only at home. There are no differences in length of training periods in these groups. Twenty one members received their basic pediatric surgical training before 1985, the year of inauguration of the association. Twelve members received post-pediatric surgery refresher courses averaging 11 months' duration, after 2-11 years. Thirteen participants of this study belongs to the founding members of the association.

To understand the current status of neonatal surgery in Korea, a survey was made among the 36 members of the Korean Association of Pediatric Surgeons. The response rate was 75 % (26 surgeons in 20 hospitals). Five hundred fifty three neonatal surgical patients treated in 1999 were analyzed. Regional numbers of patients were closely related to the regional population in most areas. Ano-rectal malformations (17 %), pyloric stenosis (16 %), Hirschsprung's disease (13 %), atresia/stenosis of the gut (11 %), esophageal atresia (8 %) were the most common anomalies treated. The majority of operations were done within the first week of life. Seventy one per cent of cases were major life threatening or so-called neonatal index cases. Over-all mortality was 8 per cent. Higher mortality was observed in patients with diaphragmatic hernia (26 %), gastro-intestinal perforation (18 %), NEC (18 %), and esophageal atresia(14 %). Higher mortality was observed in patients with extremely low birth weight (33%) and low birth weight (18 %). Associated anomalies were observed in 20 %. Prenatal ultrasound was performed in 36 per cent with sensitivity of 20 %. Result of this study was compared to the previous report (1994) and that of Japan (1998).

After the Fukushima accident, future nuclear systems are especially focused on a passive safety without additional external electricity. A Very High Temperature gas-cooled Reactor (VHTR) has shown great chance for its inherent safety. Its safety feature is the Reactor Cavity Cooling System (RCCS), which can remove the nuclear residual heat by natural convection and radiation without additional electricity and coolant injection. KAERI is constructing the RCCS thermo-hydraulic experimental facility. In this study, the emissivity with various surface modificiation conditions were measured to simulate the radiation heat transfer between the reactor vessel and RCCS.
