Purpose: This study to identify valuated the competency in nursing leadership among new nurses through the perception of nursing managers. Methods: This a total of 136 nursing managers from two general hospitals in the Seoul metropolitan area were included in this study. Nursing leadership competencies in new nurses were measured using the Student Leadership Practices Inventory developed by Kouzes and Posner. We identified priorities in the development of nursing leadership competencies for new nurses. Results: The overall importance and performance of nursing leadership competencies for new nurses were assessed by nursing managers at an average of 3.92±0.37 and, 2.84±0.50, respectively. Of the 30 nursing leadership competencies, 11 would need to be maintained and strengthened, seven would need to focus on improvement efforts, and 11 would have low priority. The last one was overdone. Conclusion Of the 18 items of high importance based on the nursing leadership competencies among new nurses identified, for seven items indicating low performance, the performance of nurses should be improved by introducing nursing leadership development programs after they enter the work environment. Eleven low-priority nursing leadership competencies require a long-term strategic approach and need to spread the understanding of nursing leadership throughout the nursing organization.

PURPOSE: The purpose of this study was to identify hospital nurses' recognition of the team system and the effectiveness of the team system as an organizational structure. METHODS: A self-report questionnaire was used to collect data from 247 general hospital nurses during 4 months in 2013. Analysis was done using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and factor analysis with SPSS 18.0. program. RESULTS: There was no significant difference in nurses' recognition of team structure (t=2.06, p=.153) or effect of team structure (t=0.36, p=.549) according to use of team system. In hospitals with a team system, there were positive correlations between recognition of the effect of the team system and age (r=.25, p=.033), and total clinical career (r=.26, p=.012). In hospitals not using a team system, nurses' recognition of team structure as an organizational system (r=.31, p<.001), nurses' recognition of team structure, total (r=.30 p<.001) correlated significantly with the effects of team system. CONCLUSION: Results of this study provide a retrospection view of the team system in nursing organizational systems. The nursing team system's ultimate goal needs to be confirmed for complementary nursing care. Also, more studies on nurses' perceptions of, and effectiveness of the team system are necessary.

Torsades de pointes, a polymorphic ventricular tachycardia associated with prolonged QT interval, is a well-known life-threatening arrhythmia, which has been found to be induced by various causes such as drugs, electrolyte imbalances, and severe bradycardia. Cisapride is a gastrointestinal prokinetic drug, which is widely used to treat gastroesophageal reflux disease or other functional gastrointestinal disorders. Cisapride can cause torsades de pointes and cases of torsedes de pointes induced by cisapride have been reported in other countries. Cases of torsades de pointes associated with antihistamine drugs have been reported in Korea, however, cisapride-induced torsades de pointes case has not been reported. We report a case of 31 year-old female patient who experienced repeated loss of consciousness due to cisapride-induced torsades de pointes.

PURPOSE:Recent studies proposed that polyunsaturated fatty acids (PUFA) of the omega6 series (linoleic acid, LA) compared to the omega 3 series (linolenic acid, LNA) may be a potent promoters of adipogenesis during the gestation/lactation period. Increased ratio of LA/LNA may stimulate adipose tissue development during gestation/lactation period and may subsequently lead to chilhood obesity. The purpose of this study is to evaluate fatty acids composition of the breast milk in Korean lactating women and to analyze the relationship between LA/LNA and the body weight gain of the infants. METHODS:Fifty eight healthy postpartum lactating women and their healthy 58 breast feeding infants were studied. At 11.3+/-3.9 days of postpartum, breast milk were taken and analyzed by gas-liquid chromatography with one-step methylation method. RESULTS:The total fat contents in breast milk were 3.2+/-1.3%. The total fat contents in breast milk were not related to maternal BMI or Kaup index of infants. The percentage of PUFA was 24.9+/-6.0%. Among these PUFA, the percentage of LA and LNA was 20.3+/-5.8% and 2.2+/-0.8%, respectively. LA/ LNA ratio was 10.2+/-2.5. There were no significant correlations between LA/LNA ratio and infant weight gain during the first 2 months of life. CONCLUSION: Short term weight gain of infant was not related to the LA/LNA ratio in the breast milk. Further studies on the long term effects on fat percent and body weight of infants would be needed.

The current socioeconomic climate has meant more children spend more time alone at home even for dining. This study was performed to characterize modem Korean childrens' food ecology based on mealtime atmosphere. A total of 705 elementary school students, 347 girls and 358 boys took part in the study. They were chosen evenly from the Seoul metropolitan areas, provincial cities, or rural areas, and were asked to fill out a questionnaire. The questionnaire was categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The average height, weight, body mass index, and Rohrer index were 143.2 cm, 37.6 kg, 18.2 and 127.2 respectively. A significant number of children(39.2%) answered their bed time was between 11 and 12 pm. Only 28.3% answered that the whole family has breakfast together, and 47.7% have dinner together. A considerable number of children, 17.8% for breakfast and 6.9% for dinner, answered they eat alone. Most of the children answered they like to have dinner with the whole family. Half of the children answered they do not feel hungry before having breakfast. Proportions of children for their favorite meal time were 66.8%, and 25.4% and 7.8% for dinner, school lunch, and breakfast respectively. The largest proportions of children, 53.3% and 68.7%, have breakfast and dinner at home. Most of the children(75.2%) never purchase their dinner. Forty two% of the children answered they like school lunch, however, 60% of children answered they leave portions of lunch uneaten occasionally or always. Only 38.0% and 46.2% of the children have nutritionally adequate diet for breakfast and dinner. Children having more meals with the whole family possessed a more positive attitude towards breakfast compared to the children who eat with the whole family less frequently. In conclusion, Korea children are exposed to different health threatening food ecology problems related to changing environments, and consistent concern and support from community nutritionists are required.

This study was performed using mealtime atmosphere to characterize the food ecology of Korean children residing in different regions of Korea. A total of 705 elementary school students, 347 girls and 358 boys, were divided into three groups according to the areas where they lived, which included Seoul (n = 230), provincial cities (n = 273) and rural areas (n = 202). The subjects were asked to fill out questionnaires which were categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The results showed that the average height (p < 0.01), weight (p < 0.01) and body mass index (BMIs)(p < 0.01) of the rural group were significantly lower than those of the Seoul and provincial city groups. A significantly higher proportion (10.4%) of the rural group was from disfunctional families, including single parent families, than those of the Seoul (1.7%) or provincial city (4.4%) groups. However, a larger number of children from Seoul ate alone, did not enjoy their meals, and hardly talked to each other during breakfast time, compared to those from the provincial city or rural areas. Also, the proportion (33.0%) of 'good' in balance of meal was the lowest (33.0%) in Seoul of the three areas (p < 0.01). Most of the children answered that they liked having breakfast and dinner with the whole family. In conclusion, the food ecology of elementary children differed according to the regions in which they resided. Although children from Seoul had higher BMIs, their nutritional intake was not satisfactory, and their undesirable food ecology could be a contributing factor.

OBJECTIVE: The aim of this study was to determine the optimal loading conditions for pure intrusion of the six maxillary anterior teeth with miniscrews according to alveolar bone loss. METHODS: A three-dimensional finite element model was created for a segment of the six anterior teeth, and the positions of the miniscrews and hooks were varied after setting the alveolar bone loss to 0, 2, or 4 mm. Under 100 g of intrusive force, initial displacement of the individual teeth in three directions and the degree of labial tilting were measured. RESULTS: The degree of labial tilting increased with reduced alveolar bone height under the same load. When a miniscrew was inserted between the two central incisors, the amounts of medial-lateral and anterior-posterior displacement of the central incisor were significantly greater than in the other conditions. When the miniscrews were inserted distally to the canines and an intrusion force was applied distal to the lateral incisors, the degree of labial tilting and the amounts of displacement of the six anterior teeth were the lowest, and the maximum von Mises stress was distributed evenly across all the teeth, regardless of the bone loss. CONCLUSIONS: Initial tooth displacement similar to pure intrusion of the six maxillary anterior teeth was induced when miniscrews were inserted distal to the maxillary canines and an intrusion force was applied distal to the lateral incisors. In this condition, the maximum von Mises stresses were relatively evenly distributed across all the teeth, regardless of the bone loss.

PURPOSE: The purpose of this study was to compare the retention of the two denture adhesives with a silicone edentulous model and a resin denture base in vitro study. MATERIAL AND METHODS: The experimental groups were used two denture adhesives and classified into 5 subgroups each. Subgroups were divided by the number of times the saliva sprayed. The control group was used synthetic saliva only. Dislodging tensile strengths were applied to the resin denture base using Instron in 3 directions : vertical, lateral, and anterior-posterior. RESULTS: The retention of two denture adhesives was increased significantly than saliva alone (P < .05). In each denture adhesives, the retention of saliva sprayed first was decreased than denture adhesive alone, but it didn't have significant differences. Whenever saliva sprayed repeated, the retention was decreased significantly than saliva sprayed first (P < .05). In each denture adhesives, vertical retentive force was highest than lateral and anterior-posterior retentive forces, and anterior-posterior retentive force was higher than lateral retentive force. This results were significantly different (P < .05). Significant differences of the retentive ability among two denture adhesives were not observed. CONCLUSION: From the results, use of the denture adhesives resulted in improved retentive ability of denture. Especially retentive force was highest in vertical direction.
