The sleep is the most important problem for new parents. However, there were very rare the study about sleep of normal neonates and early infants in Korea. So we attempted pilot survey study of neonates' sleep pattern. The purpose of this study was to investigate the sleep pattern of normal neonates in Seoul and Kyungki area and to provide for basis for nursing intervention for parents of them. The subjects of this study were 37 normal full-term neonates of 2~3weeks of age who were visited by researcher or assistant at postpartum care unit, health care clinic, outpatient clinic located in Seoul and Kyungki area from April 20, 1999 to March 15, 2000. This study was descriptive survey study under the convenient sampling method. The instrument of this study was the NCASA translated by Korean Parent Child Health Academic Association. The collected data were coded as 1/4hour unit, and analyzed by MS Office Excel program. The result of this study were as followed: 1. The mean amount of total sleep was 15.1hours. The mean amount of daytime sleep was 9.5hours. The mean amount of nighttime sleep was 5.7 hours. The mean amount of longest sleep was 2.9hours. The mean amount of shortest sleep was 0.6hour. 2. The mean amount of total activity was 8.9hours. The mean amount of daytime activity was 6.5 hours. The mean amount of nighttime activity was 2.3hours. The frequency of feeding was 10.4 times a day. The frequency of daytime feeding was 7.3 times. The frequency of nighttime feeding was 3.1 times. It is suggested that various subjects and more data according to age, and comparative study among different cultures are needed for further study in the future.

Automated blood pressure monitors have gained acceptance in many clinical settings with the increasing demand, the accurate BP measuring devices reguire the need for validation. We have evaluated the Dinamap 8100, an oscillometric automated blood pressure monitor, using the Mercury sphygmomanometer as a reference. Comparison of sphygmomanometers was conducted 60 patients (30-Normotensive group, 30-Hypertensive group at Seoul National University Hospital. Two trained observers took measure blood pressure(systolic/diastolic) at the same time using the Dinamap 8100 on one arm and the Mercury on the other. For each measurement, the device was randomly selected from a group of devices repetively used for the experiment. Mean readings for systolic pressure with the Dinamap 8100 in normotensive group were lower(mean difference ; 4.26mmHg) than the Mercury type. Mean readings for systolic pressure with the Dinamap 8100 in hypertensive group were lower(mean difference ; 9.05mmHg) than the Mercury type. Mean readings for diastolic pressure with the Dinamap 8100 in normotensive group were lower (mean difference ; 7.46mmHg) than the Mercury type. Mean readings for diastolic pressure with the Dinamap 8100 in hypertensive group were lower(mean difference ; 9.03mmHg) than the Mercury type. We have found that blood pressure readings with the Dinamap 8100 were lower than those with the Mercury type. we are using the Mercury type in clinics, although it has observer bias and terminal digit preference. But the Dinamap 8100 is readily portable, simple to use, and capable of preventing observer bias and terminal digit preference. The Dinamap 8100 is acceptable for blood pressure determination in subjects who are normotensive or hypertensive ones.

The survival of Very Low Birth Weight (VLBW) infants has been improved with the advancement of neonatal intensive care. However, the incidence of accompanying gastrointestinal complications such as necrotizing enterocolitis has also been increasing. In intestinal perforation of the newborn, enterostomy with or without intestinal resection is a common practice, but there is no clear indication when to close the enterostomy. To determine the proper timing of enterostomy closure, the medical records of 12 VLBW infants who underwent enterostomy due to intestinal perforation between Jan. 2004 and Jul. 2007 were reviewed retrospectively. Enterostomy was closed when patients were weaned from ventilator, incubator-out and gaining adequate body weight. Pre-operative distal loop contrast radiographs were obtained to confirm the distal passage and complete removal of the contrast media within 24-hours. Until patients reached oral intake, all patients received central-alimentation. The mean gestational age of patients was $26^{+2}$ wks ($24^{+1}{\sim}33^{+0}$ wks) and the mean birth weight was 827 g (490~1450 g). The mean age and the mean body weight at the time of enterostomy formation were 15days (6~38 days) and 888 g (590~1870 g). The mean body weight gain was 18 g/day (14~25 g/day) with enterostomy. Enterostomy closure was performed on the average of 90days (30~123 days) after enterostomy formation. The mean age and the mean body weight were 105 days (43~136 days) and 2487 g (2290~2970 g) at the time of enterostomy closure. The mean body weight gain was 22 g/day after enterostomy closure. Major complications were not observed. In conclusion, the growth in VLBW infants having enterostomy was possible while supporting nutrition with central-alimentation and the enterostomy can be closed safely when the patient's body weights is more than 2.3 kg.

Purpose: This study was to investigate the relationship between the palpebral fissure and the exophthalmos in an elder women population in Korea subjects with normal eye status. Methods. From November 2014 to July 2015, The author analyzed the morphological values in 81 Korean elder women population. The clinical test was performed using the Hertel exophthalometer and verner califer. Analysis of data were described using the spss 20 and Pearson's test. Results. The mean age of the 81 subjects (162 eyes) was (73.938+/8.585)mm. The mean value of palpebral fissure was (5.673+/-2.065)mm in width and (24.179+/-4.409)mm in height. The mean value of exophthalmos was (5.537+/-2.151)mm. There were a significant relationship(P>0.01) in the mean size between the width and height in palpebral fissure. Also, there were a significant relationship(P>0.01) in the mean size between the palpebral fissure width and exophthalmos. Also, there were a significant relationship(P>0.01) in the mean size between the palpebral height width and exophthalmos. However, there were not significant relationship(P>0.01) in the mean size between the palpebral fissure width and exophthalmos in right eye. On the other hand, The relationship between right eye and left eye of the palpebral fissure and exophthalmos was similar results. Conclusions. In this study, these results suggested that the palpebral fissure and exophthalmos was a significant relationship in the mean value of morphologic characters in Korean elder women population.

Background: Prognostic value of prophylactic level VII nodal dissection in papillary thyroid carcinoma has been highlighted. Materials and Methods: A total of 27 patients with papillary thyroid carcinoma with N0 neck underwent total thyroidectomy with level VI and VII nodal dissection through same collar neck incision. Multicentricity, bilaterality, extrathyroidal extension, level VI and VII lymph nodes were studied as separate and independent prognostic factors for DFS at 24 months. Results: 21 females and 6 males with a mean age of 34.6 years old, tumor size was 5-24 mm. (mean 12.4 mm.), multicentricity in 11 patients 2-4 foci (mean 2.7), bilaterality in 8 patients and extrathyroidal extension in 8 patients. Dissected level VI LNs 2-8 (mean 5 LNs) and level VII LNs 1-4 (mean 1.9). Metastatic level VI LNs 0-3 (mean 1) and level VII LNs 0-2 (mean 0.5). Follow-up from 6-51 months (mean 25.6) with 7 patients showed recurrence (3 local and 4 distant). Cumulative DFS at 24 months was 87.8% and was significantly affected in relation to bilaterality (p-value <0.001), extrathyroidal extension (p-value <0.001), level VI positive ((p-value <0.001) and level VII positive ((p-value <0.001) LNs. No recurrences were detected during the follow-up period in the absence of level VI and level VII nodal involvement. Conclusions: Level VII prophylactic nodal dissection is an important and integral prognostic factor in papillary thyroid carcinoma. A larger multicenter study is crucial to reach a satisfactory conclusion about the necessity and safety of this approach.

Sea Surface Salinity (SSS) observations from the Aquarius satellite in the East Sea show large systematic biases mainly caused by the surrounding lands and Radio Frequency Interferences (RFI) along the descending orbits on which the satellite travels from the Asian continent to the East Sea. To develop a technique for correcting the systematic biases unique to the East Sea, the least square regression between in situ observations of salinity and the reanalyzed salinities by HYCOM is first performed. Then monthly mean reanalyzed salinities fitted to the in situ salinities are compared with monthly mean Aquarius salinities to calculate mean biases in $1^{\circ}{\times}1^{\circ}$ boxes. Mean biases in winter (December-March) are found to be considerably larger than those in other seasons possibly caused by the inadequate correction of surface roughness in the sea surrounded by the land, and thus the mean bias corrections are performed using two bias tables. Large negative biases are found in the area near the coast of Japan and in the areas with islands. In the northern East Sea, data sets using the ascending orbit only (SCIA) are chosen for correction because of large RFI errors on the descending orbit (SCID). Resulting mean biases between the reanalysis salinities fitted to in situ observations and the bias corrected Aquarius salinities are less than 0.2 psu in all areas. The corrected mean salinity distributions in March and September demonstrate marked improvements when compared with mean salinities from the World Ocean Atlas (WOA [2005-2012]). In September, salinity distributions based on the corrected Aquarius and on the WOA (2005-2012) show similar distributions of Changjiang Diluted Water (CDW) in the East Sea.

The present study was undertaken to clarify the changes in blood chemical values of indigenous Korean striped calves according to age. Blood samples were collected from 15 calves (8 females and 7 males) reared at the Gyeongsangbukdo Livestock Research Institute and the levels of various chemicals in serum were analyzed. The mean total protein, albumin and globulin concentration in calves increased from 2 weeks after birth, and the levels in females were higher than those in males at 8 weeks after birth. The mean glucose concentration increased significantly at 2 weeks after birth. The mean blood urea nitrogen concentration increased from 2 weeks after birth, whereas the mean creatinine concentration decreased significantly from 2 weeks after birth. The mean uric acid concentration increased gradually from 2 weeks after birth. The mean glutamic oxaloacetic transaminase and glutamic pyruvic transaminase concentration increased significantly from 2 weeks after birth. The mean total bilirubin concentration tended to decrease from 2 weeks after birth. The mean triglyceride, total cholesterol and high density lipoprotein cholesterol concentration increased significantly from 2 weeks after birth. In conclusion, the data obtained from this study may be valuable as a standard for interpreting results of biochemical analyses in indigenous Korean striped calves.
