The present study was aimed to evaluate the incidence, etiological factors, and management of cleft lip and palate. Two hundred and twenty patients with cleft lip and/or cleft palate who were treated at Department of Oral and Maxillofacial Surgery, Chonnam National University Hospital, during the period between January 1994 and December 2003 were reviewed. The ratios of cleft lip : cleft lip with cleft palate : and cleft palate were 0.4:1.1:1. Males were more common than females in cleft lip (1.3:1) and cleft lip and palate (2.5:1), while females were more common than males in cleft palate (1:1.3). In the cleft side, left clefts were more prevalent than right clefts (cleft lip 1.3:1, cleft lip and palate 1.6:1). Unilateral clefts were more common than bilateral clefts in cleft lip (79:21). Cleft lip and cleft palate were more common in those with blood type A (34.5%) than those with other types. There was no significant relationship between birth season and frequency of clefts. The clefts were common in the first-born (48.8%), and in mothers aged between 25 and 29 (51.7%). Medication (24.7%) and stress (16.7%) during the first trimester were noted. Positive familial history was noted in 13 cases (5.9%). Thirty-two cases (15%) were associated with other congenital anomalies, in which tonguetie (40.6%) and congenital heart disease (21.9%) were most common. Among 100 patients with cleft palate, 77 patients had middle ear disease (77%), which occurred predominently in the incomplete cleft palate. Seventy-six among the 77 patients received myringotomy and ventilation tube insertion, and the remaining one received antibiotic medication only. Cleft lips were treated primarily at 3 to 6 months, and cleft palates were at 1 to 2 years. Treatment regimens included modified Millard method mainly in the cleft lip, and Wardill V-Y, Dorrance method, and Furlow method in the cleft palate. The percentage of palatal lengthening as type of cleft palate was greater in the incomplete cleft palate group (11.2%) than in the complete cleft palate group (9.6%). The percentage of palatal lengthening as operating method was no difference between the Furlow method (10.9%) and the push back method (10.7%). As postoperative complications, hypertrophic scar was most frequent in the cleft lip, and oronasal fistula in the cleft palate. In summary, it was shown that medication and stress during the first trimester of pregnancy were frequently associated with cleft lip and cleft palate, adequate timing and selection of method of operation are important factors to obtain morphologically and functionally good results. Furthermore prevention and treatment of middle ear disease are important in cleft palate patients because of its high co-occurrence.

The purpose of this study is to investigate the CPR within ambulance. The Subjects were 890 emergency medical technicians in fire department in Gyeonggido. After continuing education program, the emergency medical technicians completed the questionnaires from January to February, 2012. Questionnaire consisted of demographic characteristics, method of chest compression (one handed or two handed), chest compression - ventilation ratio, and hands only CPR. Data were analyzed by frequency analysis and Chi-square test, t-test. One-way analysis of variance (ANOVA) was followed by Scheffe post-hoc test to analyze changes in all parameters between all groups. One handed chest compression accounted for 14.0% and two handed chest compression accounted for 86.0%. Hands only CPR accounted for 71.7% and standard CPR (30:2) accounted for 28.3%. In order to perform the high quality CPR, as least three persons must be dispatched in the ambulance. The flexible management of manpower may improve the survival from the cardiac arrest. A systemic approach for educating and training EMT's in CPR is needed.

Congenital diaphragmatic hernia (CDR) with severe pulmonary hypoplasia is associated with significant mortality. Recently, several new therapeutic methods have been suggested, such as high-frequency oscillatory ventilation and inhaled nitric oxide. For hypoxemic respiratory failure unresponsive to these advanced medical treatment options, extracorporeal membrane oxygenation (ECMO) serves as the last potentially effective treatment. An understanding of the pathophysiology of pulmonary hypertension associated with CDH led to a strategy involving preoperative stabilization and delayed surgical intervention with ECMO. We describe four cases of ECMO, including the first report of ECMO for neonatal CDH in Korea.

Thermal stress of livestock has been issued due to recent climate change trends and this causes reproductive disorders, decreased feed consumption, immunosuppression, and increased mortality of animals. Concept of THI has been widely used to quantitatively evaluate the degree of thermal stress for animals, however use of this concept is restricted for animals living in the enclosed facilities such as mechanically ventilated broiler houses. In this study, time-based internal energy flow and variation trends of temperature and humidity were analyzed based on BES technique. Local weather data, insulation characteristics of building materials, heat and moisture generation rate from broilers according to age, algorithm of ventilation operation were adopted for boundary condition of the model to accurately compute THI values inside the mechanically ventilated broiler house. From the BES computation, excess frequency of THI threshold in Jeju city was highest on the assumption that air conditioning equipments were not installed. When general raising density ($39kg\;m^{-2}$) was adopted, total 2,191 hours were exceeded. Excess hours of THI threshold were strongly related to the cumulative air temperature ($R^2=0.87$).

Objectives The purpose of this study is to find the relationships between the allergy and weakness in children in Seong-Dong district. Methods 802 day care centers children were participated for survey on allergic disease, risk factors, and weakness. From the result, we analyzed the relationships between the aforementioned factors. Results 1. 802 children were participated for the survey. We eliminated survey answers with unclear answers, and selected 792 survey sheets as our final subject of study. The age of majority of subjects(720 children) were between one to six years old, and the others were under the age of one and over seven. 2. The prevalence rate of asthma in a lifetime was 6.69%, allergic rhinitis was 14.87%, atopic dermatitis was 28.82%, allergic conjunctivitis was 6.29%, food allergies was 9.58%, and drug allergies was 1.4%. In 2009, the prevalence rate of allergies during treatments is 6.69% for asthma, 13.41% for allergic rhinitis, 13.64% for atopic dermatitis, 4.13% for allergic conjunctivitis, 5.23% for food allergies, 0.96% for drug allergies. 3. The significant risk factors were types of dwelling, pet with fur, dirty environments without vacuum cleaners, the numbers of times bed covers were washed, frequency of air ventilation, changes in body after moving, family history. 4. The distribution of the number of children with weakness within the five visceras were respiratory weakness, digestive weakness, psychoneurologic weakness, neuromotor weakness, and urogenital weakness in the order of most to the least. More specifically, children who only has respiratory weakness were the majority, while children who have respiratory and digestive weaknesses, children who have respiratory, digestive, and psychoneurologic weaknesses, children who have respiratory and psychoneurologic were followed. 5. With the exception of children with urogenital weakness, Most of the children with respiratory weakness, digestive weakness, psychoneurologic weakness, and neuromotor weakness had been treated for allergies in 2009, while children who were diagnosed with allergic diseases at least once in their lifetime most likely had weak respiratory, digestive or psychoneurologic systems. Conclusions The results of this study showed that there was a correlation between children with weak viscera and children with allergic diseases. However, further research would be necessary.

The purpose of this study was to examine the demand of parents and teachers for a children's library and analyze the need in consideration of their age and children's library-using frequency. The subjects in this study were 1,500 parents and teachers in the region of Gwangju, on whom a survey was implemented to find out the necessity of a children's library, what should be considered in terms of design and program development and what forms of materials should be provided. As a result of checking their needs for the functions of a library, the parents and teachers investigated attached importance to culture, welfare and hands-on culture/art programs as what a library should focus on. Second, as for design, they gave top priority to comfortableness(sanitary facilities, ventilation, humidity and temperature) and safety(sofas, cushions and carpets for children). Third, as to program preference, both of the parents and teachers considered activity, performance and educational programs necessary among multiple kinds of ongoing programs. Specifically, performance programs ranked first among the parents and third among the teachers. Activity programs ranked first among the teachers and third among the parents. Fourth, concerning the importance of materials possessed by a library, they placed the most emphasis on the kind of materials that could foster creativity and instill the right personality.

There are considerable controversies in the management of congenital diaphragmatic hernia. By 1997, early operation, routine chest tube on the ipsilateral side and maintainingrespiratory alkalosis by hyperventilation were our principles (period I). With a transition period from 1998 to 1999, delayed operation with sufficient resuscitation, without routine chest tube, and permissive hypercapnia were adopted as our practice. High frequency oscillatory ventilation (HFOV) and nitric oxide (NO) were applied, if necessary, since year 2000(period II). Sixty-seven cases of neonatal Bochdalek hernia from 1989 to 2005 were reviewed retrospectively. There were 33 and 34 cases in period I and II, respectively. The neonatal survival rates were 60.6 % and 73.5 %, respectively, but the difference was not significant. In period I, prematurity, low birth weight, prenatal diagnosis, inborn, and associated anomalies were considered as the significant poor prognostic factors, all of which were converted to nonsignificant in period II. In summary, improved survival was not observed in later period. The factors considered to be significant for poor prognosis were converted to be nonsignificant after change of the management principle. Therefore, we recommend delayed operation after sufficient period of stabilization and the avoidance of the routine insertion of chest tube. The validity of NO and HFOV needs further investigation.

Major purposes of this study were to investigate the administration patterns of analgesics and sedatives in SICU and to identify the factors influencing the use of prn analgesics and sedatives by ICU nurses. The sample of this descriptive study was 50 adult patients in SICU and 53 ICU nurses. Patient's medical records were reviewed to investigate names, doses, the routes of administration, the interval of administration, and the type of prescription of sedatives and analgesics administered. Study medications were narcotics, hypnotics, and antipsychotics. To identify the factors influencing the use of prn analgesics and sedatives, 53 ICU nurses checked 9 items, and rank them from first to fifth. The selection of items was based on the previous studies and the experience of the investigator. The results of the study are as follows: 1. The mean age of the subjects was 53 years, 24 patients out of 50 subjects had received mechanical ventilation therapy. Most of the patients received neurosurgeries and abdominal surgeries. 2. For 4 days, 13 total study medications and combination of these were administered to the patients. Commonly prescribed drugs were Ketoprofen and Midazolam. Twenty six to fourty two percent of the patients did not receive any drugs for at least one day during the four days. 3. On the average, the study drugs were administerd 1.4 to 2.6 times per day during 4 days. 4. More than 50 percent of the prescription was as-needed (prn) except those of the POD 3. Fourteen percent of the patients did not have any prescription for sedation and pain control after surgery. 5. Examination of the frequency of sedatives and analgesics bolus administration revealed that a greater number of doses were given during daytime (from 7 am. to 7 pm.) than nighttime (from 7 pm. to 7 am.). The difference was significant at Alpha, .05. 6. First factor that most influenced nurses to administer sedatives and analgesics for intubated patients was the evaluation of patient's vital signs (51%). For non- intubated patients, the factors that nurses considered important were the patients' complaints of pain (64%) and evaluations of patients' vital signs (23%). In conclusion, the results of this study indicate that patients in SICU might not receive enough analgesics and sedatives to feel completely free from pain during the post operational period. Future study should be focused on the evaluation of the adequacy of current practice for pain and anxiety control in terms of the SICU patient's response.

Purpose: The aging of society has rapidly progressed, especially in Korea. Therefore, the necessity of research on end-of-life (EOL) care in elderly patients has increased. However, there are few studies on EOL care intensity for non-cancer patients. This study was designed to compare the EOL care intensity between cancer and non-cancer patients. Methods: We retrospectively analyzed the EOL care intensity based on medical records of decedents of Kyung Hee University Medical Center, a tertiary referral hospital from December 2014 through March 2015. And we compared EOL care intensity between cancer patients and non-cancer patients using statistical analysis of the frequency of invasive procedures and logistic regression analysis for factors that affect the EOL care intensity. Results: Statistical analysis showed invasive procedures, such as intensive care unit admission, endotracheal intubation followed by mechanical ventilation and emergency dialysis, were performed more frequently in non-cancer patients than cancer patients (29.3% vs. 72.4%, P<0.001). And age (P=0.038) and morbidity of cancer (P<0.001) influenced the invasive procedural decision when analyzed by logistic regression analysis. Conclusion: The EOL care was more intensive in non-cancer patients, and age and morbidity of cancer were major factors for the treatment intensity.

This study was attempted to know the awareness of Advance Directives of adults in Gandwon-do province. Data was surveyed from 60 adults in Gangwon-do province by 42 item questionnaire for the awareness of Advance Directives. Subcategories of Advanced Directives questionnaire were knowledge, preference, experience for life-sustaining treatment and Advance Directives. The data was analyzed with the frequency and percentage using SPSS 24.0. 45% of Participants replied they knew the 'life-sustaining treatment' exactly. They preferred CPR 78.3%, mechanical ventilation 63.3% and blood transfusion 51.7% for their future special life-sustaining treatments. They did not preferred hemodialysis 8.3%, artificial respiration 6.7%, intensive care unit 6.7%, 8.3 percent of participants said that they well aware of Advance Directives. 86.6% of them hoped to write their Advance Directives. Despite such low awareness of the Advance Directives, the intention to write Advance Directives was high. Based on these results, it was found that the level of awareness of Advance Directives was very important for the intention to prepare Advance Directives. Therefore, regional programs and education on Advance Directives and periodic survey study for awareness of Advance Directives should be continued.
