The study aims to examine the knowledge and awareness of care workers on oral health knowledge at the geriatric care facilities in order to improve and develop oral health services. For the research method, the study carried out a questionnaire survey to 163 care workers working at the geriatric care facilities (10) in D Metropolitan City from May 1~31, 2015 and then the collected data were statistically analyzed. As a result, the oral health knowledge of care workers was 20.09 points out of total 26 points (77.2%). The highest knowledge was 'proper toothbrushing method' with 93.0% and the lowest one was 'knowledge on the use of oral supplementary goods' with 58.1%. Those with experience of oral health education had higher demand on oral health education (P<0.001), and those with higher experience of oral health education had significantly higher oral health knowledge (P<0.001), demand (P<0.01) and awareness (P<0.05). As for factors influencing care workers' oral health awareness, if they had higher oral health knowledge points (P<0.01), oral health education demand (P<0.01), they had higher oral health awareness level. Accordingly, it is required to provide efficient, sustainable and practical oral health education of care workers considering oral characteristics of the long-term hospitalized patients at the care hospital. And, the role of dental hygienist as the person in charge of oral health education is necessary. Therefore, institutional support from the government is required to assign professional personnel.

Background: Lung cancer continues to increase and one half of all cases of lung cancer occur in patients age 65 years and older. However, it seems that lung cancer is less treatable in elderly patients because of co-morbid illness or poor tolerance of surgery and chemotherapy. The intention of this study is to seek an adequate treatment approach for lung cancer in the elderly through an understanding of its characteristics. Method: The clinical data of 207 patients who were diagnosed with histologically proven lung cancer at the department of internal medicine in Seoul Municipal Boramae Hospital between September 1994 and August 1998 were retrospectively analyzed according to their age groups; group I$\geq$65 years(n=122) and group II<65 years(n=85). Results: The peak incidence of age was 7th decade(36.2%) and male age 65 years and older were 42% of all patients. Although dyspnea was more common in group I(26%) than in group II(11%)(p=.0l), there were no significant difference in other symptoms, stage, and histologic type between two groups. Group I significantly had more patients with poor performance(ECOG 3&4) than group II(35.2% vs.12.9%, p=.000). The percentage of patients with non-small cell carcinoma received supportive care only was significantly higher in group I than in group I(74% vs. 35%, p=.000). However, survival of patients who had curative intent treatment was similar between two groups(median survival 11.3 mos vs. 23 mos, p>.05). The histologic subtype, stage and performance status were significant prognostic factors affecting survival, but age itself was not. Conclusion : Lung cancer is prevalent in the elderly and aggressive diagnosis and treatment should be considered in elderly patients with good performance status.

Purpose : We studied clinical patterns of the febrile infants and children presenting to the Pediatric Emergency Department(ED) in the general pediatric population. Method : We analyzed 1,764 infants and children who had a history of measured body temperature of $38.3^{\circ}C$ or higher, before or after arrival at Pediatric ED of Ilsan Paik Hospital from September 2004 to August 2005. We analyzed their clinical patterns, such as the frequency of febrile illness, age distribution, monthly distribution, diagnosis. Result : The frequency of the febrile illness at Pediatirc ED was 19.9 percent (1,764/8,881 cases). The percentage of admission into hospital was 26.4 percent. The most common age group presenting to Pediatric ED with febrile illness was the 12-23 months group(22.8 percent) followed by the 4-11 months group and the 2 years group. In May, the most numerous patients presented to the Pediatric ED with febrile illness. The frequency of febrile illness was significant higher in the 'Spring & Summer group' compared to the 'Autumn & Winter group'. The ratio of male to femal was 1.4:1. The most common diagnosis was acute pharyngitis(42.5 percent), followed by acute gastroenteritis (15.3 percent), pneumonia(7.0 percent). Conclusion : The frequency of the febrile illness at Pediatirc ED was 19.9 percent. The most numerous patients visited Pediatric ED in May. And, the most common age group was 12-23 months. The proportion of non-urgent disease, such as acute pharyngitis, acute gastroenteritis, acute nasopharyngitis and acute bronchitis, was high. There is a need to educate parents and improve the medical system in Korea.

Purpose : We evaluated the prevalence and clinical, microbiological features of extrapulmonary tuberculosis (EPT) in pediatric patients. Methods : We retrospectively reviewed medical records of pediatric patients diagnosed with EPT at The Catholic University of Korea, Incheon St. Mary's Hospital between 2000 and 2007. Results : Of 109 patients diagnosed with tuberculosis (TB), 12 patients (11%) were admitted with EPT. At 2006-2007, the proportion of patients with EPT among patients with TB was the highest (20%) comparing with last 6 years. The ratio of male to female patients was 1.4:1 and the mean age was 9.2 years (range, 3 months-15 years). The involved sites were pleura in 5 (41.6%), central nervous system in 3 (25%), miliary TB in 2 (16.7%), gastrointestinal tract in 1 (8.3%) and bone and joint in 1 (8.3%). The most common symptom at admission was fever (91.6%) and mean duration of fever was 15.8 days (range, 0-47 days) in spite of the proper treatment. Confirmed rate for acid fast bacillus stain, culture, and polymerase chain reaction were 33.3%, 41.6% and 41.6%. Of 5 culture proven cases, 4 (80%) were resistant to more than one antituberculosis drugs. Eleven patients recovered without complication and 1 patient died. Conclusion : Total incidence of TB decreased steadily according to the nationwide survey. However, our results suggest that the proportion of diagnosis with EPT among diagnosis with TB in children has increased. Microbiological diagnosis of EPT in children was more difficult than that of pulmonary TB. And drug resistance rate has increased.

Objective : The PDSQ is a brief and psychometrically strong self-report scale designed to screen for common DSM-IV Axis I disorders in clinical settings. In this study, the K-PDSQ was compared with the M.I.N.I.-Plus (Mini-International Neuropsychiatric Interview-Plus) for diagnostic validity and availability of the K-PDSQ as a part of standardization of the K-PDSQ. Methods : The 640 patients were evaluated with the K-PDSQ and the M.I.N.I.-Plus. Diagnosing with the M.I.N.I.-Plus, the diagnostic correspondence, administering time, sensitivity, specificity, ROC curve, and AUC of the K-PDSQ were evaluated. Results : For the diagnostic correspondence of the K-PDSQ, Cohen's kappa coefficient was .66 between the K-PDSQ and the M.I.N.I.-Plus. The administering time of the K-PDSQ was $18.2{\pm}11.80$ minutes. Both sensitivity and specificity of the K-PDSQ were higher: the mean sensitivity across 10 subscales of K-PDSQ was 86%; the mean specificity was 84%. All AUCs of each subscale were above .80, which were statistically significant. Conclusion : The K-PDSQ is valid and available as a diagnostic screening tool. It will be widely used in clinical settings for screening DSM-IV Axis I diagnosis because of its simplicity and high reliability.

In this study, the health insurance application of PET and the change in the pay standard were examined, and the amount of health insurance use over the past 10 years was analyzed. Positron tomography was applied as health insurance in 2006, and after ¹⁸F-FDG was first applied as health insurance, positron tomography tests using various radioactive isotopes have been applied as health insurance. As of 2019, the number of positron emission tomography tests was 198,651 cases, and the treatment amount was about 88.3 billion won, and the number of tests according to general characteristics was higher in men than in women, and by age, the number of tests was the highest in 60s. The number of outpatient examinations was higher than that of inpatient examinations, and the number of examinations in tertiary hospitals(68.2%) was significantly higher than that of general hospitals and hospitals. As for the test site, torso test was the most common at 86.6%, and radioisotope was the most at 93.6% using ¹⁸F-FDG. The change in the use of PET for 10 years increased steadily from 2010 to 2014, but the amount of use decreased sharply afterwards as the recognition of asymptomatic long-term follow-up tests was deleted due to the government's change in health insurance application standards in 2014. As changes in health insurance standards have a great influence on changes in health insurance usage, continuous monitoring will be required in the future.

This study is a descriptive survey research conducted to examine the influence of learning efficacy on nursing students' self-confidence. Research subjects included a total of 231 university students in D city, and the data were analyzed by t-test, ANOVA, Pearson's correlation coefficients, and multiple regression. The study results were as follows: Learning experience was high in the order of vital sign check, intramuscular injection, and subcutaneous injection. Recognition of importance was also high in the order of vein therapy, intramuscular injection, and vital sign check. Self-confidence was high in the order of vital sign check and wearing of protective equipment. As for the learning experience, there were significant differences depending on the students' school year. As for the correlation among all variants, 'learning experience of nursing skills', 'self-confidence', 'learning self-efficacy', and 'self-efficacy' had a positive correlation with each other. Based on these study results, it is necessary to develop an educational strategy that ensures students' education of self-efficacy and improvement of their learning experience to enhance their self-confidence.

Objective: This study aimed to investigate the pattern of psychiatric consultation-liaison in a new general hospital over a 5-year period. Method: Retrospective chart review was conducted for psychiatric consultations performed from May 2004 to December 2008 in a new general hospital in Hwasun, Korea. Results: A total of 1,852 patients who were referred to the Department of Psychiatry for consultation were included in the analysis. The main reasons for psychiatric consultation were changes in mental status(20.5%), depression(16.8%), insomnia(12.8%), and anxiety(7.9%). Psychiatric consultations were conducted with diagnoses of delirium(39.7%), depressive disorder(28.2%), adjustment disorder(7.9%), and anxiety disorder(4.1%). Patients with delirium were significantly older than were those with other psychiatric diagnoses(p<0.001). Delirium was more common in male patients than in female patients(47.1% vs. 29.9%, respectively), and depression was more common in female patients than in male patients(48.3% vs. 33.9%, respectively)(p<0.001). Delirium was more common in patients who underwent surgical operation than those who did not(p=0.010). Conclusion: Delirium was the most common diagnosis for psychiatric consultation followed by depression in a university hospital. Delirium was more prevalent in men than in women, while depression was more common in women.

Objectives : The purpose of this study was to investigate the clinical characteristics of antipsychotic medication prescription for the symptom control in patients with delirium. Methods : One hundred and eighty-five patients referred to consultation-liaison psychiatric services for delirium due to general medical condition were included in this study. All subjects were divided into two groups (antipsychotics users vs. antipsychotics nonusers), and comparison analyses on their clinical characteristics were performed. Results : One hundred and twenty nine patients (66.5%) used antipsychotics for their delirium, and 56 patients (30.3%) did not use antipsychotics. The history of psychotropic medication was more frequently observed in antipsychotic users (5.4% vs. 18.6%, χ²=5.498, p=0.022). Especially, the history of benzodiazepine use was significantly high in antipsychotics users. The total score and sub-items of delirium rating scale-severity items except for the psychomotor retardation item showed higher scores in antipsychotic users than in nonusers (all p<0.05). The total score of the delirium rating scale-diagnosis items was higher in antipsychotic users than in the nonusers (p=0.010). Conclusions : Delirium patients with more severe delirium symptoms and with more history of benzodiazepine use were treated with antipsychotics more frequently than those without. These findings imply that benzodiazepine may not only exacerbate delirium but be associated with aggression or psychomotor agitation that need immediate intervention. Clinicians may need to pay attention not only these external symptoms but also to hypoactive symptoms that may lead to misdiagnosis and undertreatment.
