Obstetric problems concerning macrosomia were evaluated by retrospective review of 91 pregancies that resulted in the delivery of an infant weighing 4,000gm or more at the Yeungnam University Hospital during 3 1/2 years from Jun. 1983 to Oct. 1986. The results obtained were as follows. 1. Macrosomic infants weighing 4.000gm or more occured in 2.8% of the deliveries. 2. 65.9% of macrosomic infants and 53.5% of total infants were male. The ratio of male was statistically higher in the macrosomic infants than in the total infants(P<0.05). 3. The incidence of macrosomia was higher with increasing qestational age, and deliveries at 42 weeks or more gestation were more common in the macrosomic infants than in the total infants(P<0.01). 4. The incidence of macrosomia was highter with increasing parity, and stastically higher in the multipara than in the primipara(P<0.01). 5. There was no difference in the incidence of macrosomia between the mothers aged 24 or less and that of 30 or more. 6. The cesarean section rate of macrosomia(30.8%) was stastically higher than that of the total infants(15.7%)(P<0.01) 7. With the pregnacy and delivery of macrosomic infants, 22 antepartum anemia(24.2%), 10 postpartum hemorrhage(11.0%), 9 birth canal injury(10.0%), 7 prolonged second stage of labor (7.7%), 4 breech presentation, and 3 pregancy induced hypertension occured in the mothers, and 10 asphyxia(or Apgar score 6 or less), 2 shoulder dystocia, 1 intrauterine fetal death, and 1 sacrococcygeal teratoma occured in the infants.

The Gogunsan Archipelago is composed of two island groups; the first group includes Mal-do, Myeong-do, Gwangdae-do, and Bangchuk-do islands consisting of Neoproterozoic rocks, and the second group includes Yami-do, Sinsi-do, Muneo-do, Jangja-do, and Seonyu-do islands consisting of Cretaceous rocks. The first group mainly consists of the Bangchuk formation which can be divided into two layers; the lower layer was more deformed than the upper layer. The former was intruded by mafic and felsic volcanic rocks formed in the volcanic arc tectonic setting 930-890 Ma and the latter was deposited ca. 825-800 Ma. In these islands, large scale folds with east-west fold axes were beautifully formed; the Maldo island fold was designated as natural monument and large scale beautiful chevron fold was developed on the Gwangdae-do island. In addition, there are unique zebra-shaped outcrop formed by a mixing of basic and acidic magma and Independent Gate shaped outcrop formed by coastal erosion. On the other hand, the Yami-do, Sinsi-do, Muneo-do, Jangja-do and Seonyu-do islands consist of 92-91Ma Cretaceous volcanic rocks and, in Sinsi-do island, the Nanshan formation deposited ca. 92 Ma. These Cretaceous volcanic rocks formed by melting of the continental crust by the heat supplied from the uplifting mantle due to the extension caused by a retreat of subducting ocean slab. Yami-do and Sinsi-do islands are composed of rhyolite. In Yami-do island, bands with vertical joint formed by cooling of the bottom part of the lava, are shown. In Sinsi-do island, large-scale vertical joints formed by cooling of lava flow, were developed. The Jangja-bong of Jangja-do island and Mangju-bong of Seonyu-do island are composed of brecciated rhyolite and formed a ring shaped archipelago contributing to the development of marine culture by providing natural harbor condition. They also provide beautiful views including 'Seonyu 8 views' along with other islands. As mentioned above, the Gogunsan archipelago is rich in geoheritages and associated cultural and historical resources, making it worth as a National Geopark.

A nationwide survey was conducted to investigate the annual occurrence rate of neonatal sepsis, maternal risk factors in neonatal sepsis, localized infection in neonates, causative organisms in nosocomial infection and the most common causative organism for neonatal sepsis in Korea. Clinical and bacteriological data wele collected from 37 neonatal units to perform retrospective review of the medical records of the newborn infants who were confirmed as having neonatal sepsis and whose blood culture was collected to isolate organisms for one year study period from January to December in 1997. 78,463 neonates were born at 37 hospital in 1997, and 20,869 neonates were admitted to the neonatal units, During this period, 772 episodes of neonatal sepsis were recorded in 517 neonates. The occurrence rate of neonatal sepsis was 0.73%(0~2.95%). Male to female ratio was 1.15:1, and 303 cases(42.1%) were born prematurely. The main pathogens of early onset of sepsis were S. aureus(20%), S. epidermidis(14.4%) and coagulase negative staphylococcus(14. 4%). Gram negative bacilli including Enterobacter spp (7.2%), E. coli(5.1%), Klepstella(4.5%), Pseudomonas(3.7%) and Enterobacter faectum(3.6%) accounted for 24.1% of sepsis. Group B beta-hemolytic streptococcus were isolated only in two cases. Common obstetric factors were PROM(21.1%), difficulty delivery(18.7%), fetal tachycardia(5.3%), chorioamnionitis(4.9%), and maternal fever(4.7%). The main pathogens of late-onset sepsis were S. aureus(22.3%), S. epidermidis(20.4%) and CONS(9.9%). There were 6 cases(1.0%) of Candida sepsis, Frequent focal infections accompanying sepsis were pneumonia(26.1%), urinary tract infection(10.5%), meningitis(8.2%), and arthritis(3.6%), S. epidermidis(22.0%) and s. aureus(21.7%) were also the most common pathogens in 373 nosocomial infection.

The 46 patients were investigated with the congenital infant muscular torticollis referred Dept. of physical therapy in Dong San Medical Center from January in 1995 to January in 1996. 1. The ratio between males and females was scaled to 1.5 : 1.23 cases(50.0 %) were involved with left side and 22 cases(47.8 %) involved with right side, and one case was of bilaterality. 2. Sequence of birth, the first bone babys were the most distributed with 34cases(73.9 %), the second bone babys were followed with 11cases(23.9 %). 3. There were normal deliveries 60.8 %, Cearean section deliveries 23.9 %, difficulty deliveries .0 % and breech presentation was 2.2 %. 4. The case of cephalic asymmetry consisted 60.0 % of all congenital torticollis and most frequently found at the age of all $5\sim8$ weeks(45.7 %). In 26.1 % of all congenital torticollis cases, facial asymmetry was found and these cases were most frequently in the age of $5\sim8$ weeks(26.1 %), also in the age group of $9\sim12$ weeks and $17\sim20$ weeks consecutively(each 3 %).(P<0.05) 5. The duration of therapy required differently according to the severity of the torticollis, in mild cases, it took $1\sim2$ weeks cases(30.4 %) revealed high therapeutic effect in 54.3 % of the cases. In moderately involved cases(30.4 %), therapy required $3\sim4$ weeks in 13 % of the cases showed improvements. In the most severely involved cases, (7 %) it took more than $9\sim10$ weeks of therapy and showed improvement in 6.5 % only.(P<0.005) 6. The result of this study showed the best therapeutic effects were noticed in the mild cases of congenital torticollis(24 cases 45.6 %) and excellent improvement in moderately involved cases (28.1 %) and 13.1 % of the most severely involved cases(P<0.05).
