Sleep apnea refers to a condition in which a person does not breathe during sleep, and is a dangerous symptom that blocks oxygen supply in the body, causing various complications, and the elderly and infants can die if severe. In this paper, we present an algorithm that classifies sleep breathing by analyzing the intensity of breathing with images alone in preparation for the risk of sleep apnea. Only the chest of the person being measured is set to the Region of Interest (ROI) to determine the breathing strength by the differential image within the corresponding ROI area. The adult was selected as the target of the measurement and the breathing strength was measured accurately, and the difference in breathing intensity was also distinguished using depth information. Two videos of sleeping babies also show that even microscopic breathing motions smaller than adults can be detected, which is also expected to help prevent infant death syndrome (SIDS).

An important, albeit rare, cause of fetal bradycardia is long QT syndrome (LQTS). Congenital LQTS is an ion channelopathy caused by mutations in genes encoding cardiac ion channel proteins. Fetal onset of LQTS imposes high risk of life-threatening tachyarrhythmias and sudden cardiac death. Here, we report the case of a female newborn with fetal onset of bradycardia and a 2:1 atrioventricular (AV) block. After birth, a 12-lead electrocardiogram (ECG) revealed bradycardia with QT prolongation of a corrected QT (QTc) interval of 680 ms and pseudo 2:1 AV block. Genetic testing identified a heterozygous Gly402Ser (c.1204G>A) mutation in CACNA1C, confirming the diagnosis of LQTS type 8 (LQT8). The patient received propranolol at a daily dose of 2 mg/kg. Mexiletine was subsequently administered owing to the sustained prolongation of the QT interval and pseudo 2:1 AV block. One week after mexiletine inception, the ECG still showed QT interval prolongation (QTc, 632 ms), but no AV block was observed. There were no life-threatening tachyarrhythmias in a follow-up period of 13 months.

Traumatic uterine rupture is uncommon but can be fatal and life-threatening for both the mother and infant. In addition to complications caused by trauma itself, such as pelvic fracture, gestational complications such as placental abruption, abortion, premature labor, rupture of membranes, maternal death, and stillbirth can occur. In particular, fetuses have been reported to have a high mortality rate in cases of traumatic uterine rupture. A 35-year-old pregnant female patient fell from the fourth floor and was admitted to our trauma center. We observed large hemoperitoneum, pelvic fractures, and spleen laceration, and the fetus was presumed to be located outside the uterus. The pregnant woman was hemodynamically unstable. Although the fetus was stillborn, angioembolization and surgical treatment were properly performed through collaboration with an interventional radiologist, obstetrician, and trauma surgeons. After two orthopedic operations, the patient was discharged after 34 days. This case report suggests the importance of a multidisciplinary approach in the treatment of pregnant trauma patients.

We r viewed a policy of primary surgical closure of large ventricular septal defects in small infants. Sixty-three infants met criteria for inclusion in the study, and were divided into two groups based on age: group 1 infants aged less than 5 months(n = 31), and group 2 infants aged 5 months or more(n = 32). Both groups had similar variation in ventricular septal defect location(paramembranous versus muscular), and showed no significant difference in left to right shunt and in ratio of systemic and pulmonary vascualr resistance. Three early deaths(9.7%) occurred in group 1, but no death(0%) in group 2. The causes of death were preoperative cardiac arrest and cerebral injury followed by postoperative respiratory insufficiency in two patients, and preoperative tracheomalacia followed by laryngeal edema and respiratory arrest in one Two patients in group 1 showed postoperative low cardiac output syndrome(6.5% in group 1 versus 0% in group 2). There was no late death during the follow-up per od in both groups. No surviving patients had postoperative patch leakage, or required a second operation. These results indicate that primary surgical closure of large ventricular septal defects, if logical perioperative care is accompanied, can be saefly performed in small infants aged less than 5 months with low postoperative mortality or morbidity rates.

The family environment children are exposed to growing up greatly influences their future potential and achievements. Previous findings show that changes in family structure during childhood, particularly those resulting from divorce or death, cause lasting negative consequence that affect the child physically, psychologically, economically, and socially. Unfortunately, single-parent households are becoming increasingly common in Korea, nearly doubling to more than a million cases in the last two decades. Existing domestic and international studies of this area tend to focus on the short-term effects of growing up in a single-parent household. In addition, these studies group their samples in ways that result in findings that may be too broad or are not necessarily an accurate representation of the subjects. This study attempts to address some of these shortcomings by focusing on the long-term effects of how changes in family structure early in children's lives affect achievement during their transition to adulthood. In addition, it takes into account the development cycle the child is in at the time of family restructuring, and what kind of long-term effects result from that. In this analysis, we find that there are several cases of statistically significantly differences in domain achievement depending on the developmental stage the child was in when the parental divorce or death occurred. The findings indicate that changes in family structure during the infant/toddler period influence health condition and depression, while changes in family structure during middle-childhood and adolescence do not. Meanwhile, changes in family structure during any point in the developmental stages have negative effects on educational attainment, with the severity of these negative effects depending on when the family changes occur. The negative effect on educational attainment is most prominent when a change in family structure occurs during the infant/toddler period, followed by adolescence, then middle-childhood.

A survey was conducted by the staff of the College of Medicine and School of Public Health, Seoul National University in cooperation with Seoul Special City from 1 December 1967 through 28 February 1968, on such events as delivery, death, abortion and pregnancy. The survey directed to a total population of 47,811 residing in 9,157 households led us to the following findings: 1. Two year averages of crude birth rate, crude death rate and natural increase rate were 30.1, 5.6 and 24.5, respectively. 2. Of all deliveries, home and hospital deliveries constituted 61.1 per cent and 35.5 per cent, respectively. 3. Deliveries other than hospital deliveries were found to be attended more often by mother-in-laws (26.5 per cent) than by doctors or midwives(23.4 per cent). 4. About 51 per cent of all women having experiences in pregnancy during the last two years had an experience of consulting a doctor at least one time throughout whole period of pregnancy. 5. In most cases scissors were used to cut umbilical cords, of which 71.0 per cent were not sterilized and only 20.3 per cent sterilized. 6. In many cases placenta was incinerated(48.2 per cent) and on many other occasions it was thrown away into water(28.3 per cent). 7. Cement bags(37.4 per cent), gauze and absorbent cotton(29.8 per cent) were found to be most frequently used to receive new-born babies. 8. In 1966 8. 8 per cent of the women had at least one abortion induced and in 1967 the percentage was 9.2 per cent. 9. Nearly all(95.8 per cent) of the induced abortions reportedly were done at doctor's clinics. 10. Of all the abortions induced 65.3 per cent were done by specialists in obstetrics, 30.3 per cent by general practitioners and 2.7 per cent by midwives. 11. Those who experienced spontaneous abortions were 1.9 per cent of all women both in 1966 and 1967. 12. About 9.2 per cent of women investigated were found to be currently pregnant. 13. Age specific death rate turned out to be highest among those under 1 year of age. 14. Ten major causes of death in their order of frequency were: 15. Places of death can be classified into homes(75.3 per cent) and hospitals(13.2 per cent). 16. Method of disposing of corpses comprised burials(54.2 per cent) and cremations(44.6 per cent). 17. Infant, neonatal and hebdomadal mortality rates have been computed at 32.2, 18.9 and 13.7, respectively. 18. Infants were found to have died either at homes(81.5 per cent) or at hospitals(18.5 per cent). 19. Birth registrations had been done for about 18.5 per cent of the dead infants.

This thesis presents the research of analytical psycholoy in respect of Jindo Dasiraegi. In a funeral of Jindo, situated in the southern island of Korea, there is a theatrical performance which is called Dasiraegi(rebirth). This research manifested a basic, universal meaning of psychological approach related the implicit of death in performing theatre from a analytic psychological point of view. The characteristics of this theatrical feast are like these ; 1) funeral festival 2) entrance of clown(the existence of antipole and conflict) 3) eroticism 4) active participation of female character 5) difficulty in her delivery 6) the moment of joy thanks to childbirth. The prerequisite of this feast should be a propitious mourning of person dying old and rich. That is, after having a complete life, it could be an entire death. Three main roles in Dasiraegi ; a bat-blind buddhist devotee, a strolling actor teasing men, an apostate monk, theses characters lock horns in a form of triangle conflict relations, then they keep a balance with a fake mourner as a protagonist , modulator and narrator. These characters are indeed clowns who manifested a metaphor as a decent, sacred and reasonable part of shadow regards group consciousness. The alive and the deceased, mourner and fake mourner, piety and confusion, wail and laugh, silence and grumble, death and birth, diverse antipole all coexist then theses are in harmony. The blind devotee and the monk are in antipole, the entertainer(anima) provokes a conflict between them. The infant is a solution as same as a result of conflict. This conflict seems to be eased by birth of a baby which is a symbol of wholeness(ganzheits) but the conflict of antipole is reenacted as insisting his parental right so this solution is leaving the baby to the chief mourner who is fourth character and the first beginning. Unconsciousness, hereby, is negotiating with appeared reality. The Images in unconsciousness are conscious and this new energy in unconsciousness is proceeding towards consciousness, then it became a therapeutic power for the loss of consciousness. Dasiraegi is the play of consolation much more for the alive than the deceased. The death signified not a loss but a resurrection and this intends a transition of new leading independent role for the alive. These make us have more prudent consideration concern the double sense of renewal for the dead and the alive. It is preserved as only a form of drama on stage after disappearance of Dasiraegi in a funeral recently. Dasiraegi was a manifestation of unconsciousness for compensation about the unilateral attitude of group consciousness to the strict death excessively. Therefore, this will enable reflect the relativeness and the attitude which regards the death as the end today.

Over the past four decades reproductive behavior has changed rapidly in much of the developing countries. The average total fertility rate has fallen by half from six or more to near three today. Between 1960 and 2000 the largest fertility decline occurred in Asia and Latin America. The mortality rate has decreased in most developing countries. The purpose of this study is to review the pattern of demographic transition in developing countries. At first, this study focuses on the regional fertility transition. In Africa, the total fertility rate has decreased from 6.59 to 4.85 between 1960 and 2000. However, the rate has rapidly fallen from 5.76 to 2.34 in East Asia. The same pattern is found in Latin America. The mortality rate has also decreased in most of developing countries. It is also interesting to find that there is a clear difference among developing countries. In terms of crude death rate, Latin American countries show the lowest rate, while African countries remain still high rate. The study also shows the relationship between socioeconomic indicators and fertility/mortality in developing countries. The result supports the hypothesized relationship between education and fertility. However, the effects of urbanization and income on fertility do not show consistent result. About mortality rate, however, the study shows the significant relationship between urbanization and infant mortality rate, between income and mortality. The study finally emphasizes that we should include 'AIDS' in the study of mortality in African countries.

Between December 1994 and October 1996, 57 premature infants with evidence of a hemodynamically significant PDA associated with cardiopulmonary compromise underwent indomethcin therapy(Group I, n=48) or surgical ligation(Group II, n=9) because of indomethacin failure. The gestational alee(29.6$\pm$ 3.1weeks vs. 28.1 $\pm$ 1.6weeks) and birth weight(1,413 $\pm$ 580gm, ,098 $\pm$ 235gm) showed no significant differences between the two groups. Medical management included fluid restriction, diuretics, and indomethacin therapy(one or two cycles). Surgical libation was done at the neonatal intensive care unit(NICU) without moving the patient to the operation room. There was no complication associated with the operation. There were 9 deaths in Group I(19%, 9/48) and 2 deaths in Group II(22% , 219). The main causes of deaths were persistent bronchopulmonary dysplasia with sepsis(n=8) and intrapulmonary hemorrhage(n=3). The rate of medical treatment failure including death and complication in premature infants whose body weights were less than 1500gm was higher(41%, 15/38) than in premature infants whose body weights were more than 1500gm(16%, 3/19). Early surgical ligation of PDA may be applicable in the premature infant with a large size, low birth weight(<1500 gm), or associated intracardiac anomalies. Perfoming the operation in the NICU may be safe in s ead of moving the patient to the operating room.

Over the past four decades reproductive behavior has changed rapidly in much of the developing countries. The average total fertility rate has fallen by half from six or more to near three today. Between 1960 and 2000 the largest fertility decline occurred in Asia and Latin America. The mortality rate has also decreased in most developing countries. The purpose of this study is to review the pattern and characteristic of demographic transition in developing countries. At first, this study focuses on the regional fertility and mortality transition. Africa, the total fertility rate is still high, can be match to the second stage of demographic transition. Similar case is found in Southern West Asia areas. However, the fertility rate has therd stage of demographic transition. The same pattern is found in Latin America. The mortality rate has also decreased in most of developing countries. It is interesting to find that there is a clear difference among developing countries. In terms of crude death rate, Latin American countries show the lowest rate. while African countries remain still high rate. About mortality, African countries show a high level in terms of both crude death rate and infant mortality rate. African countries also show the lowest level of life expectancy in the world. One of the reasons for low level of life expectancy in Africa is the widespread of AIDS in this areas. This study suggests that we should include 'AIDS' in the study of mortality in African countries.
