PURPOSE: This is a qualitative study to identify dimensions of long-term care hospital care quality that provide high-level medical services for long-term care patients in Korea. METHODS: Service consumers and providers were interviewed, and collected data were analyzed into thesis, type and dimension. The focus group method was applied to two provider groups and individual interview was applied to two persons who had experienced a long-term care hospital. RESULTS: The results of analyzing the comsumers and providers was integrated into 8 dimensions: physical environment, staff, clinical care and nursing, multiplicity of activity program, atmosphere, interaction with family, nutrition, and quality improvement system. CONCLUSION: The dimensions of long-term care hospital care quality from this study can be used as a basis of quality indicators. Quantitative studies to test these dimensions are required for establishing quality management systems.

The prevalence of obesity has been increasing worldwide, which raises concerns about the disease burden associated with obesity. Socioeconomic status (SES) has been suggested to be associated with obesity and obesity related diseases. This study aimed to evaluate the time trend in socioeconomic inequality in obesity-related mortality over the last decade in Korean population. We evaluated the influence of education level, as an indicator of SES, on obesity-related mortality using death data from the Cause of Death Statistics and the Korean Population and Housing Census databases. The rate ratio of the mortality of people at the lowest education level as compared with those at the highest education level (relative index of inequality [RII]) was estimated using Poisson regression analysis. Between 2001 and 2011, RII (95% confidence interval) for overall obesity-related disease mortality increased from 2.10 (2.02–2.19) to 6.50 (6.19–6.82) in men, and from 1.94 (1.79–2.10) to 3.25 (3.05–3.45) in women, respectively. Cause-specifically, the same trend in RII was found for cardiovascular mortality and mortality from diabetes mellitus, whereas the RII of mortality from obesity-related cancers in men did not show the similar trend. Subgroup analysis stratified by age revealed that the RII of obesity-related mortality was much higher in younger people than in older people. In conclusion, there has been persistent socioeconomic inequality in obesity-related mortality in Korea, which was more evident in younger people than in older people and has been deepened over the last decade especially for cardiovascular disease and diabetes.

PURPOSE: This study compared the efficacy and tolerability of intravenous (i.v.) phenobarbital (PHB) and i.v. levetiracetam (LEV) in children with status epilepticus (SE) or acute repetitive seizure (ARS). METHODS: The medical records of children (age range, 1 month to 15 years) treated with i.v. PHB or LEV for SE or ARS at our single tertiary center were retrospectively reviewed. Seizure termination was defined as seizure cessation within 30 minutes of infusion completion and no recurrence within 24 hours. Information on the demographic variables, electroencephalography and magnetic resonance imaging findings, previous antiepileptic medications, and adverse events after drug infusion was obtained. RESULTS: The records of 88 patients with SE or ARS (median age, 18 months; 50 treated with PHB and 38 with LEV) were reviewed. The median initial dose of i.v. PHB was 20 mg/kg (range, 10-20 mg/kg) and that of i.v. LEV was 30 mg/kg (range, 20-30 mg/kg). Seizure termination occurred in 57.9% of patients treated with i.v. LEV (22 of 38) and 74.0% treated with i.v. PHB (37 of 50) (P=0.111). The factor associated with seizure termination was the type of event (SE vs. ARS) in each group. Adverse effects were reported in 13.2% of patients treated with i.v. LEV (5 of 38; n=4, aggressive behavior and n=1, vomiting), and 28.0% of patients treated with i.v. PHB (14 of 50). CONCLUSION: Intravenous LEV was efficacious and safe in children with ARS or SE. Further evaluation is needed to determine the most effective and best-tolerated loading dose of i.v. LEV.

PURPOSE: The aim of this study was to investigate the incidence and contributing factors of nonoliguric hyperkalemia in extremely low birth weight infants (ELBW) within 96 hours after birth in very low birth weight infants. METHODS: The incidence of non-oliguric hyperkalemia and difference of clinical feature between hyperkalemic (>or=7.0 mEq/L) and normokalemic (<7.0 mEq/L) groups were determined by reviewing medical records of 35 extremely low birth weight infants admitted in Samsung Medical Center between Jan. 2001 to Dec. 2001. We analyzed the serum levels of sodium, potassium, fluid intake, urine output, blood gas analysis values, and other factors that influenced serum electrolytes. RESULTS: Among 35 ELBW infants, 11 (31%) was hyperkalemia developed and 4 infants (36%) was associated with cardiac arrythmia. The incidence and onset time of hyperkalemia showed inverse correlation with birth weight and gestational age. Perinatal complications and serum levels of sodium, fluid intake, hourly urine output, and other blood gas analysis were no different in both groups. Dopamine administrations, UAC insertion rate, ICH incidence and base deficit were significantly increased in hyperkalemic group. CONCLUSION: Non-oliguric hyperkalemia is a frequent complication of ELBW infant. Serum potassium should be monitored closely to avoid life threatening cardiac arrhythmia in these infants.

PURPOSE: This study was to analyse the factors affecting youth smoking, especially self-efficacy and perceived social norm, based on the stage of change. METHODS: A self-reported survey was conducted during the period from the 21st of April to the 17th of May, 2008. Data were collected from 10,707 students of 12 middle schools in Seoul, Gyeonggi-do, and Incheon. The data were analysed with SPSS/WIN 15.0. RESULT: The smoking possibility was 2.18 times higher in the male students than in female students, and 1.76 times higher in 8th-grade students and 2.48 times higher in 9th-grade students than in 7th-grade ones. Smoking possibility increased when students had more experience in alcohol, more friends who smoke, or worse relationship with their parents. Also this study showed that high-level self-efficacy and perceived social norm were acting as inhibiting factors of smoking. CONCLUSION: To reduce the youth's smoking rate, smoking prevention programs should provide educational chances to learn knowledge and skills on how to reject smoking temptation. Also, someone significant like parents should make it clear to the youth that they do not want their children to smoke.

PURPOSE: To analyze the stress distribution of the implant and its supporting structures through 3D finite elements analysis for implants with different hexagon heights and to make the assessment of the mechanical stability and the effect of the elements. MATERIALS AND METHODS: Infinite elements modeling with CAD data was designed. The modeling was done as follows; an external connection type Phi 4.0 mm x11.5 mm Osste(R) USII (Osstem Co., Pusan, Korea) implant system was used, the implant was planted in the mandibular first molar region with appropriate prosthetic restoration, the hexagon (implant fixture's external connection) height of 0.0, 0.7, 1.2, and 1.5 mm were applied. ABAQUS 6.4 (ABAQUS, Inc., Providence, USA) was used to calculate the stress value. The force distribution via color distribution on each experimental group's implant fixture and titanium screw was studied based on the equivalent stress (von Mises stress). The maximum stress level of each element (crown, implant screw, implant fixture, cortical bone and cancellous bone) was compared. RESULTS: The hexagonal height of the implant with external connection had an influence on the stress distribution of the fixture, screw and upper prosthesis and the surrounding supporting bone. As the hexagon height increased, the stress was well distributed and there was a decrease in the maximum stress value. If the height of the hexagon reached over 1.2 mm, there was no significant influence on the stress distribution. CONCLUSION: For implants with external connections, a hexagon is vital for stress distribution. As the height of the hexagon increased, the more effective stress distribution was observed.

Neuroimaging of the brain is useful diagnostic evaluation of patients with hepatic encephalopathy msofar as it is able to exclude other causes of abno rmal mental status. Recently, changes of basal ganglia on MRI characteriwd by increased signal mtensity on Tl-weighted images were reported m patients with liver cirrhosis. Signal abnormality involves mainly the globus pallidus and seems to be specific for patients with chronic liver disease. Its pathogenesis and significance are obscure, and no pathological reports have been made. We experienced 3 cases of Chronic acquired hepatic failure whose MRI showed increased signal in-tensity in the basal ganglia on Tl-weighted imaging. Our findings su-ggest that basal ganglia signal abnormality could arise as a marker of brain impairment related to deposition of an unidentified paramagnetic substance or altered intracellular water relaxation.

BACKGROUND: Several publications have reported the successful, safe use of Laryngeal Mask Airway (LMA)-Classic devices in patients undergoing laparoscopic surgery. However, there have been no studies that have examined the application of volume-controlled ventilation (VCV) or pressure-controlled ventilation (PCV) using a LMA during gynecological laparoscopy. The aim of this study is to compare how the VCV and PCV modes and using a LMA affect the pulmonary mechanics, the gas exchange and the cardiovascular responses in patients who are undergoing gynecological laparoscopy. METHODS: Sixty female patients were randomly allocated to one of two groups, (the VCV or PCV groups). In the VCV group, baseline ventilation of the lung was performed with volume-controlled ventilation and a tidal volume of 10 ml/kg ideal body weight (IBW). In the PCV group, baseline ventilation of the lung using pressure-controlled ventilation was initiated with a peak airway pressure that provided a tidal volume of 10 ml/kg IBW and an upper limit of 35 cmH2O. The end-tidal CO2, the peak airway pressures (Ppeak), the compliance, the airway resistance and the arterial oxygen saturation were recorded at T1: 5 minutes after insertion of the laryngeal airway, and at T2 and T3: 5 and 15 minutes, respectively, after CO2 insufflation. RESULTS: The Ppeak at 5 minutes and 15 minutes after CO2 insufflation were significantly increased compared to the baseline values in both groups. Also, at 5 minutes and 15 minutes after CO2 insufflation, there were significant differences of the Ppeak between the two groups. The compliance decreased in both groups after creating the pneumopertoneim (P < 0.05). CONCLUSIONS: Our results demonstrate that PCV may be an effective method of ventilation during gynecological laparoscopy, and it ensures oxygenation while minimizing the increases of the peak airway pressure after CO2 insufflation.

BACKGROUND: This cross-sectional study aimed to evaluate the prevalence of depressive disorders and factors associated in long-term cancer survivors. METHODS: A total of 702 long-term cancer survivors over 5-years in remission were recruited in a university-affiliated tertiary hospital in Korea. Self-report using the Patient Health Questionnaire-2 and the Fatigue Severity Scale assessed depression and fatigue, respectively. Demographic characteristics, cancer-related clinical characteristics, comorbidity, health behaviors, and physical symptoms were assessed through the review of medical records or a structured self-administered questionnaire. RESULTS: We identified 26.1% of patients who had a depressed mood or displayed a loss of interest. The most prevalent primary site of cancer was the stomach (65.2%), followed by lung, breast, colorectal, and thyroid cancer. We also found that 5.7% of subjects experienced double or triple primary cancers. Larger proportion among depressive group (89.1%) complained at least one physical problem than among non-depressive group (53.2%). Physical symptoms including sleep problems, dry mouth, indigestion, pain, decreased appetite, and febrile sense were more frequent in the depressive group than in the non-depressive group. The Fatigue Severity Scale scores were higher in the depressive group than in the non-depressive group (P<0.001). Multiple logistic regression analysis showed that the highest tertile level of fatigue (odds ratio, 7.31; 95% confidence interval, 3.81-14.02) was associated with the increased risk of depression. CONCLUSION: These findings suggest that careful concern about depression is necessary in long-term cancer survivors. Fatigue may be a surrogate sign for depression, and warrants further evaluation.

PURPOSE: The smoking rates among teenagers in Korea grow gradually since 1980s despite of the numerous programs for youth smoking prevention and cessation have been developed and implemented. The purpose of this study was to explore and describe the processes of habituating to smoking among teenagers using the grounded theory methodology. METHOD: Qualitative data was collected via six focus group interviews. A total of 38 people, twelve teachers and 24 middle school students participated in this study. All focus group interviews were tape-recorded, transcribed, and analyzed according to the grounded theory methodology. RESULTS: The overriding theme of the elicited grounded theory was "stepping into a quagmire by a merest chance". The student participants began smoking by a simple chance. The contingent factors to starting smoking were "discord within the family", "family member's smoking", "schoolwork stresses", or "a rebellious spirit". The conditions of smoking included accessibility, going around in group, and the lack of discipline. "Stigmatizing", "involved in mob violence", and "making a poor academic record" coexisted as the covariance of the smoking habituation. CONCLUSION: The findings of this study illustrated the comprehensive and insightful picture of the phenomena under investigation. Nursing implications and further directions for research were discussed.
