Lammas growth, a rare phenomenon for Korean red pine (Pinus densiflora), occurred in 2006. Lammas shoots showed higher frequency and longer length in Seoul's hotter urban center than in urban boundary or suburban forest sites. Frequency and length showed a close correlation with urbanization density and vegetation cover expressed in NDVI. Air temperature in the late summer of 2006 was more than $1^{\circ}C$ higher than an average year. Of the predominant environmental signals that modulate bud flush, only temperature changed significantly during the year. Differences in temperature between the urban centers, urban boundaries and suburban forests correlated with varying land-use density. The rise in temperature likely spurred lammas growth of the Korean red pine. Symptoms of climate change are being detected throughout the world, and its consequences will be clearer in the future. Considerate interest in the responses of ecological systems to the variable changes is required to prepare for unforeseeable crises. Monitoring of diverse ecological phenomena at Long Term Ecological Research sites could offer harbingers of change.

Objectives : Impaired processing of facial information is one of the broad ranges of cognitive deficits seen in patients with Schi-zophrenia. We aimed to elucidate the differences in brain activities involved in the process of facial working memory between schizophrenic patients and healthy comparison subjects. Methods : Twelve patients with schizophrenia were recruited along with twelve demographically matched healthy volunteers as a comparison group. Functional magnetic resonance imaging (fMRI) was used to assess cortical activities during the Perfor-mance of a 2-back working memory paradigm using images of neutral faces as mnemonic content. Rcsults : The patient group performed the tasks with reduced accuracy. Group analysis revealed that the left fusiform gyrus, the right superior frontal gyrus, the bilateral middle frontal gyri/insula, the left middle temporal gyrus, the precuneus, the quadrangular lobules and the vermis of cerebellum showed decreased cortical activities in the patient group. On the other hand, an increased level of activation in the lateral prefrontal cortex and the pahetal lobule was observed from the patient group, all in the right hemisphere. Conulusion : A decreased level of activity in the left fusiform gyrus among the patient group implicates inefficient processing of facial information. An increased level of activation in prefrontal and parietal neural networks from the patient group confirms earlier findings on the impaired working memory of patients with schizophrenia.

White rats were given with combined ginseng extract and 40% alcohol(group A) and 40% alcohol(group B), by catheter through Mouth, periode from 1 to 30 th day. Control A and B groups were pretreated wish ginseng entracts for 15 days. The following results were obtained; 1. In red blood cells group A was increased 1 to 30 th day. Group B was increased 1 to 7th day and then decreased 10 to 30th day 2. In serum triglyceride concentration, group A was increased 25∼30 th day but group B. was increased whole period except 3∼7 th day. 3. Decreases of Serum phospholipid and cholestero1 concentrations resulted from pretreament of ginseng extract for 15 days, but interruption or alcohol administration recovered to normallevel immediately. 4. In Serum GOT concentration group B was increased 10 to 30 th day but group A was normal level. 5. In serum protein fractionation albumin and r-globu1in concentrations were increased in both groups. 6. Serum GPT, Thymol turbidity, creatinine, total lipid and alcohol concentrations and liver alcohol dehyrogenase activity were within normal limits in compared to control group.

Human milk is the best source of nutrients for the human infant, and its nutritional and immunologic benefits are now established, In spite of these advantages, the incidence and duration of breast feeding- is decreasing in many part of the world. The purpose of the study is to collect the data on breast feeding practice in rural and urban area of Chullanamdo, Korea and to follow the trend toward breast feeding in fuutre. Between July 1981 and January 1982, 674 mothers with the children under 2 years of age have been interviewed at Out-Patient Department. The breast feeding situation at the time of interviewed was recorded. The percentage of wholly breast-fed in the age group of 0~1, 1-2, 2~3 ,3~4, 4~5, 5~6, 6-12 and 12~24 months were 61.8%, 50.0%, 51.6%, 65.2%, 50.0%, 45.7%, 23.0% and 17.3% respectively. And the percentage of partially breast-fed in the age group of 0~1, 1~2, 2~3, 3~4, 4~5, 5~6, 6~12, and 12~24 months were 29.4%, 33.3%, 25.8%, 17.4%, 34.2%, 39.1%, 8.6% and 80.0% respectively, In the incidence of wholly breast feeding, there was no correlation between deliveries in hospital and deliveries at home attended by midwives or traditional midwives. The most frequent reasons for partially breast-fed in the age group of 0~1, 1~2, 2~3, and 3~4 months were not enough breast milk.

The separation of isocytochrome C, and un-and methylated cytochrome C have 1arge1y been depended upon ion exchange chromatography. While the isoelectric focusing was, in principle, suggested of good tool for the separation of isocytochrome C, and un-and methylated cytoch-rome C because they have some different charges. This study was applied isoelectric focusing to the separtion of isocytochrome C, and un-and methylated cytochrome C. This attempt is first time as far as I know. The results of isoe-lectric focusing on the yeast isochrome C, and un-and methylated cytochrome C, and cytoch-romes C of 13 species were also presented. The PI values of 10 species were found to around pH 10. O0 using isoeleotric focusing. The separation of isocytochrome C from Saccharomyces cerevisae was also shown satisfactory results.

A clinical and hematological observation was performed on 398 nowborn infants with hyperbilirubinemia who were admitted 10 the Department of Pediatrics, Chosun University Hospital from January, 1980 ro June, 1985. The following results were obtained 1) The incidence of hyperbilirubinemia was more frequent in male(63.8%) than in female(36.2%) 2) In the observation of the gestational period, its incidence was highest in full-term neonate(70%) and the next was pre-term neonate (25%) 3) In the observation of the delivery type, the incidence was highest in neonates with normal delivery(82.0%) and the next was c-section delivery (11.0%) 4) Idiopathic hyperbilirubinemia was the most common cause of pathological hyperbilirubinemia and the next wero breast-fed induced jaundice(10.4%), infection(9.3%), blood incompatibility(8.6%) in frequent of order. 5) The most common blood types of mother-baby in ABO blood incompatibility was 0-A (48.5%) and the next was O-B(42.5%) 6) The exchange transfusion were performed on 34 cases(8.5%). The mean serum bilirubin levels before exchange transfusion were 26.7±4.9㎎% in the cases of idiopathic hyperbilirubinemia(14 cases) and 25.9±6.5㎎% in the cases of blood incompatibility (17 cases). 7) The mean bilirubin levels before and after the exchange transfusion were 26.4㎎% and 11.9㎎% respectively and reducing rate of the bilirubin by exchange transfusion was 55%. Second exchange transfusion was performed in 2 cases(5.8%).
